Definitions

  • the present invention relates to a method and a system for calculating and constructing a scaffold and a scaffold model by using computer means.
  • the scaffold model consists of a number of standard modules and data to describe standard scaffold modules. These data can be stored in storage means, which storage means contain data describing standard requirements for scaffolding.
  • the method concerns input data to define at least one surface structure of the object onto which the scaffold is fastened.
  • the method furthermore, concerns input data defining the actual size of at least a part of the structure.
  • the method defines at least a first plane module based on the circumference of the object and at least one facade based on at least length and height measures of the facade.
  • the method defines a number of scaffold levels depending on the height of the facade.
  • JP 11141115 A2 relates to the realizing of a highly reliable estimation process and to objectively verifying of the basis of estimates, estimate history and the results of estimate by estimating material costs and construction costs based on the quantities of materials by computer processing:
  • step 1 Different kinds of temporary scaffoldings hierarchically classifying the construction works in a specifying manner are selectively applied in step 1.
  • specifications or constructing conditions for selected temporary scaffoldings are set and applied in step 2 and arithmetically processed, and the kinds of materials and their quantity 3 are de- termined.
  • the materials and construction costs for the relevant work are estimated in step 6 based on a material unit price data file 4 and a percentage calculation table data file 5.
  • labour cost, material cost, material weight, list by material, heaped capacity, time schedule and temporary facility area are respectively edited, displayed and output in step 7.
  • a part of numerical data is transmitted as an input source for preparing scaffolding drawings by CAD 9. This way, a highly reliable estimation process can be realized.
  • Japanese Patent Application No. 11-346231 describes a method being able to create easily the temporary material plot plan side by side of an elevation surface by assigning scaffold materials to the elevation of a building automatically, even if software is operating as two-dimensional CAD, the temporary material plot plan side listing device and record medium which can create a scaffold drawing efficiently are offered by making top view data and elevation data correspond.
  • Means for Solution is judges whether the top view, where the scaffold arrangement appearance datum line was plotted, is used for scaffold drawing creation.
  • the datum-line point in an elevation is computed.
  • the stanchion location by the side of an elevation surface is computed by making the stanchion location which was able to be found with the top view correspond to an elevation.
  • the invention can be realized according to the method described in the preamble of claim 1 , if the computer means also perform static calculations based on input data and standard requirements for scaffolding.
  • the computer means calculate the scaffold model and illustrate the scaffold model output means, which model is manually adapted before ending the calculation.
  • a scaffold model is calculated, and the computer can show a model of this scaffold e.g. on a computer screen, where the model can be rotated and seen from different angles.
  • an information dialog will appear at this stage, giving the exact name, dimension, weight and article number of every single component mounted on the scaffold.
  • the computer means may manually adjust parameters in the scaffold. Entrances or gates can appear from the model shown on the computer screen, and a re-calculation of static values can be performed after performing corrections.
  • Subsequent to calculating the computer may perform the static calculations and a total calculation of the number of components used in the actual scaffold.
  • the computer means may define a cost of material and perform a price calculation both for renting a scaffold and for erecting and re-erecting a scaffold after use.
  • This way the new method for computer calculation can efficiently generate all necessary data for erecting a scaffold along a building facade, where all statistic calculations are performed before placing the scaffold.
  • the static and dynamic calculation is extremely useful and indispensable.
  • the present in- vention offers an excellent solution to this problem.
  • the invention provides an automatic scaffold planning based on recognition of structures and terrain. Furthermore, the type of automatic scaffold planning can be determined by settings entered by the user or by other means. Manual alterations are possible.
  • input to the computer means can be based on existing CAD data describing the object.
  • the program calculating the scaffold can process existing data concerning the necessary measurement of e.g. a building. No further input data is necessary to perform the calculation of the scaffold when the CAD data is used as input.
  • Alternative input to the computer means can be downloaded images, which images are converted into a predefined format and where an informative part of the image is selected, where an orthogonal function corrects the image so that it becomes identical to the imaginary film plane, where at least one data set is added defining a measured distance at the image.
  • input to the computer system is created by downloading an image of e.g. a building facade. It is preferred to have more input than just an image to obtain the correct size. At least one measured value must be added to the image to actually calculate.
  • the computer means can perform a load calculation, depending on a defined scaffold maximum load.
  • a maximum load factor for the scaffold and in the computer program define the load placement on the scaffold it is possible for the load to be part of the scaffold static calculations.
  • a high scaffold load can be necessary when dealing with concrete or bricks, as these materials are extremely heavy.
  • the scaffold load can be limited.
  • the person operating the computer may define the correct scaffold load.
  • the computer means can perform dynamic load calculation. Herby can movement or change of loads be part of the calculation.
  • the computer means can also calculate wind loads on a scaffold, since wind forces can have a great dynamic impact on a scaffold.
  • the calculation depends on the scaf- fold site of appliance and on which side of a building the scaffold is placed.
  • maximum wind speed the program can calculate the optimum scaffold, which can handle winds at maximum wind speed.
  • the maximum wind speed differs depending on the scaffold placement either near the shore or onshore.
  • scaffolds can be constructed differently depending on where they are to be used. To define the cheapest possible scaffold it is necessary to apply wind data to calculate the scaffold.
  • the computer means can perform a terrain calculation depending on data describing terrain characteristics.
  • the computer means can perform a calculation of a climatic shielding.
  • the computer means may calculate the climatic shield for a scaffold upper part only. As the climatic shield also has an impact on the static calculations, it is necessary to re-calculate after defining a climatic shielding on the entire scaffold or on part of a scaffold.
  • the computer means can perform a calculation of gates. Many scaffolds are to be left open around gates.
  • the computer program allows for placing gates everywhere in the scaffold and to perform special openings e.g. around windows if necessary.
  • special components to carry the weight of the scaffold are necessary, which components are to be placed above the gates so that the structure of the scaffold above the gate can carry the same load as the rest of the scaffold.
  • the computer means can perform anchor calculations.
  • the computer means also perform a calculation of the number of anchors, which are to be placed e.g. on a building facade to support the scaffold. As anchors often have to be placed in holes in the building, it is preferred to limit the number of anchors. Thus, a correct static calcu- lation of the number of necessary anchors can reduce the number of anchors actually used.
  • the computer means can perform a diagonal calculation.
  • diagonals are calculated as part of the static calculations.
  • the program allows for changes in the placement of the diagonals before finishing the design of a scaffold. Diagonals are calculated per default according to the stated rules about diagonal pattern for a specific scaffolding system.
  • the computer means can perform a number of other steps. E.g. it is possible to let the computer systems calculate the number of sections and to calculate the static load where an electric hoist is used. Latter' s can be placed in the computer model of the scaffold so there will be an ideal combination of latter' s on the actual scaffold.
  • the computer system can also calculate fitted bay deck, which overlaps other decks with 20 centimetres.
  • Fig 1 shows a scaffold designed I a few seconds by a system as here after described.
  • the method and the system concern a number of modules where the plan module is one of Projects modules, where the user has an opportunity to make different modifications with facade (scaffold system).
  • the plan module is one of Projects modules, where the user has an opportunity to make different modifications with facade (scaffold system).
  • facade facade
  • On plan drawing user can see only view from above and also by using Change level menu view from above for every separate level of scaffold/scaffold system.
  • this module user can work with facades that are already generated around the building or create separate facade/facade system.
  • New facade To add a facade user should use Tools menu ("New facade"), the window names as New facade, the length measure is the wall length, and the height is the desired standing height for scaffold.
  • the user can choose how many degrees the building is when he adds the facade.
  • buttons '24 m' and '27 m' and 'CANCEL'- for user to select between (24 and 27 m are the closest measurements below or above 25 m, which can be divided with section length 3 m). If press '24 m' or '27 m', then new facade is created with the selected facade length. If press 'CANCEL' button, then do not create fa- cade. (User must reconsider, which section lengths he wants to use)
  • the highest WTF level can be up to 2.50m. Not more. 3.0.10
  • 3.0.11 Can be added if the width of scaffold is not wider then 1.75m (for post system). For frame systems the width of scaffold can not be changed. 3.0.12 There can be several WTF widths. User can choose one of them.
  • Anchors should be fastened to the basis scaffold at walk through frame level.
  • This Walk-through bottom frame component has no AVS in middle. As illustrated on drawing on page 1, component contains a tube in the middle for mounting Standard/frame on.
  • walk through frame and gate it is possible to add walk through frame and gate to the facade.
  • walk through frame is divided in parts so that it is possible to reach gates, if it is needed.
  • Decks should be placed in top of walk through frame to protect walking men from falling parts.
  • brackets are added to the section - do not do anything. If brackets are added to facade then we need to send user request about: move scaffold to outside of WTF, Move facade together with WTF, Leave facade like it is now, even if it intersects the building. If we have facades with bracket and then user adds WTF, the same variants must be available to the user about movement scaffold on the WTF.
  • WTF/Protection fan If User adds to facade walk through frame then add protection fan: it must be at least 1 level between them. So that when user add walk through frame, protection fan must be automatically moved up (not removed).
  • WTF/ cantilever If user adds cantilever to the level and then add WTF, in case when cantilever and WTF components intersect each other system must prompt a dialog about moving cantilever up or remove cantilever. If user chooses cancel then WTF is not added. If other component is placed above the cantilever and it is not possi- bly to move it up, then system must tell user that it is not possible to move cantilever up and give a choice to remove cantilever or not to place WTF. If WTF was added and then user wants to add cantilever in level where components will intersect each other then system must prompt a dialog to user that it is not possible to add cantilever to the level.
  • the WTF 155cm has two functions:
  • Elevation 4.0.4 This icon have following properties: a) Gable height or roof degree (user can set only one parameter in this case, the other must be set as zero) b) Gable centre c) Foot of the roof d) And also left and right length and height setup.
  • gable properties Every time user edit gable properties, parameters must be set as user set them before (default values are set if add/edit gable first time). 4.0.5 There are 4 different types of gable (single, left, right and common) 4.0.6 Minimum gable height starts from 0, maximum - there is no limit. 4.0.7 There is a screen near the gable setup where user can see a gable scheme and see the way it is modified during parameters changing. During modification of gable outline must fit to window size. 4.0.8 Gable properties window appears by right click on gable icon (old version).
  • measure line shows the height of facade with added gable (facade height + gable height (including foot of the roof)). Every time gable height is changed, the height of wall is updated. 4.0.10 Remove gable by right mouse click on facade, item "Remove gable”.
  • facade must be in initial state - it must be in cantilever in top level, (was possible in old version) 4.1.1.
  • cantilever by default is placed only in top level.
  • facade with gable has cantilever only in top level (and it does not depend on the gable type) 2)
  • cantilever by default is added to the all levels.
  • cantilevers are added to the all facade levels (with gable levels if gable is present). Note: In future user must be able to choose where cantilever is placed by default
  • climate shield/shielding If user add climate shield/shielding to the facade, then all levels that include top sections must be covered with climate shield. If we have facade with climate shield/shielding and gable Then all gable sections must be covered with climate shield/shielding.
  • the UTV is the same height as the scaffold by default, and is for all sections vertically.
  • UTV When placing UTV, it can be added to a column only. 5.0.3 There are two types of UTV: UT V Tower and UT V Deck.
  • UTV Tower is a free standing section that can have any width depending on stairway length. 5.0.5 UTV deck cannot be linked to a section which is smaller or wider. It can be linked to a section that has the same width. 5.0.6 UTV can be fastened to cantilever (in top or in all levels) which is added to the section. If user remove cantilever then UTV must be fastened to the ba- sis scaffold.
  • UTV The length of UTV can be changed. It depends on the stairway of the UTV. 5.0.8 Guardrails must be added for stabilization at every 2 m at each side of
  • the height of UTV is defined by the height to UTV top deck. 5.0.10
  • the user can set properties (height, tower/deck) fig. 16
  • UTV for frame systems is a separate section and for post systems it is fastened to the post of facade
  • UTV must be connected to the basis scaffold with couplers. Remove inside base jacks on UTV frames. Connect frames with couplers for each 2m. System must check if you have a component under the reference for AVS and it is also necessary to check if you horizontal and post or top post. If you missing some of this component you need to make it with tube and couples instead.
  • brackets of suitable width In frame system we use brackets of suitable width and then connect them with tubes by couplers (swivel couplers) from the both sides. Tubes are added each 4 m in height (each 2 levels from bottom). And before adding the UTV to the walk through frame we ask user about where he wants the access to UTV: in all levels or only in top? If WTF and cantilever is added to facade and the length of cantilever + scaffold width is less then we need to reach WTF, cantilever of smaller width is replaced with cantilever of the most suitable width. If we have WTF and user chooses to add UTV deck with access only in top level, then system must send request about in this case we can only place UTV tower. Otherwise if user chooses to have access in all levels from UTV deck, it is possible to do.
  • UTV/ Rubbish chute It is not possible to add rubbish chute and UTV to the same section. If one of these items is added then the other must be disabled in menu. But it is possible to add rubbish chute in cantilever section after UTV, if UTV has not the same dimension as section has (For ex. If section is 3.5 and UTV is 2.5m then it is possible to add rubbish chute in cantilever section after UTV).
  • Bracket (not cantilever bracket) of 0.7m is fastened to place deck 0.6m. 5.5.3 AVS is placed to on horizontal, and Im post is placed to fasten guard rail.
  • UTV/safety gate If user adds UTV to the section, then if user chooses to add safety gate to the facade, safety gate must be added to all sections except UTV section. In UTV section safety gate item must be disabled. If user wants to add UTV to the section with safety gate then a dialog must be prompted for user with choice to remove safety gate or not. But in case if UTV section as narrower then section, then it must be possible for user to add shielding to his small part of section even if safety gate is added to the other sections in facade.
  • Fig. 34 Start place tubes from the 2 nd level (right side of UTV) and from the 3d level (left side of UTV). Repeat diagonal placement every 4 levels up. Place them in top of level. Couplers must be placed every 2m in top of frame to connect UTV frames to each other.
  • guard rail between UTV and basis scaffold must be connected to UTV frame with 2 couplers, because there is nothing at inside of frame construction to connect guard rail to it.
  • guard rail must be placed to close access from UTV and prevent scaffolder from falling down. This could happen if we have that cantilever GR is placed not against UTV stairway, but somewhere higher or lower, so that it is not possible for user to reach ladder in cantilever section.
  • protection fan If user adds protection fan then symbol in plan drawing appears, and in elevation side view there is a section with a protection fan. 6.0.3 Protection fan can be removed and added also from elevation side. 6.0.4 Can be used above a gate, door or in the whole facade length.
  • protection fan can be about 1.50 metres out from building (and it's not depends on the width of cantilever (if it is added to facade). 6.0.7 If add terrain that is higher then 2m then protection fan is moved one level up. 6.0.8 If we have a facade height of 4 m, and terrain line goes higher up than 2 m, then it must not be possible to add protection fan.
  • protection fan component 6.0.11 It is not possible to separate parts of protection fan component 6.0.12 If facade has gate then protection fan must go one level up, so that all protection fan sections can be fastened to posts/frames.
  • Cantilever can be added in a level from the Protection fan level i.e. if protection fan is added in Level 2, cantilevers can only be added in level 4 or above.
  • Protection fan adjusts to the gate height (so that it can be fastened from bottom) and is put up in all sections.
  • Protection fan + Net If protection fan is added to the facade then net/plastic must be placed down to protection fan deck.
  • Protection fan + Plastic If protection fan is added to the facade then net/plastic must be placed down to protection fan deck.
  • climate shield There is a symbol of climate shield added in plan drawing. 7.0.2 At the elevation view all sections in top will be covered with climate shield (the sections are marked out with blue colour).
  • climate shield can be added to the facade top level or to the section separately. 7.0.4 It is placed outside the section (guard rails and other parts of section are covered by climate shield.
  • climate shield is added to the top sections then climate shield is just simply fastened to the neighbour posts (climate shield is simply bound to the posts by hand). So iron in top sections must be removed from the side which is connected to the post of facade. We have two irons from the both sides of section for example in top highest section for added gable.
  • climate shield covers all space between building and scaffold and also cantilever and/or bracket.
  • climate shield must cover all sections which were added and become as top now, section under this added, and sections from the left/right side of these top sections, so that all top was covered.

For example if some section or simple gable is added, then all gable sections including the lowest top level are covered with climate shield. All top sections except electric hoist are covered with climate shield. 7.0.16 If scaffold is equal 0.7m or less then don't need to add standard/posts from inside. If scaffold is wider then we need to place these posts (see image below).

  • Use tube for guard rail fastening Use 2 couplers to fasten tube to the posts. Use 2 couplers to fasten guard rail to the tube. Fig. 68
  • Number of movements means, how many times the workers will move electric hoist in a certain scaffolding project. (If we for example have 3 scaffold sides, and it will be necessary for the workers to move it 2 times for hoist of material etc.) Each time an electric hoist is moved, it will cost the customer xx amount of money, and therefore it will affect the calculation.

So it is necessary to check references for double and single guard rail, if there is no component for double guard rail we use two singles guard rails but in post system we also can place two horizontals. 14.12.3Guard rail in 0 level. 14.12.3.1 Post system:
  • bottom guardrails 1. In level 0, the lower point of bottom guardrail must not sit higher than 0,80 m from the ground. 2. The distance between the lowest point of guardrail in level 0, and the lowest point of guardrail in next level (level 1) must not exceed 2,80 m. Fig. 89
  • Text should be: 'Use horizontals in level 0'
  • guard rails in +8 system There are 3 components that can be used as guard rails in +8 system: double, horizontals and tubes.
  • double guard rails we are allowed to use horizontals. If system can't find double guardrails, then system should tell user what other components are avail- able, and give him the opportunity to choose, what he prefers.

  • guard rails There are 2 types of guard rails: single and tubes.
  • guard rail type we are allowed to use double end guardrail and tubes, even if you have single guardrail in the rest of the scaffold. If for ex. user chooses single guard rail and system can't find end guard rail of appropriate length, system can automatically place two single guard rails from end sides (also including top).
  • Tubes are placed instead of single guard rail. But in top from end sides we still use top frame component and not in top we use end guard rails (double). In bottom tubes instead of single guard rails must be placed.
  • Double guard rails are placed from outside except 0 level. In bottom (0 level) we need to place single guard rail in highest connection point on frame for guard rail. 3) Tubes

Description

Method and system for design of a scaffold
Field of the Invention
The present invention relates to a method and a system for calculating and constructing a scaffold and a scaffold model by using computer means. The scaffold model consists of a number of standard modules and data to describe standard scaffold modules. These data can be stored in storage means, which storage means contain data describing standard requirements for scaffolding. The method concerns input data to define at least one surface structure of the object onto which the scaffold is fastened. The method, furthermore, concerns input data defining the actual size of at least a part of the structure. Moreover, the method defines at least a first plane module based on the circumference of the object and at least one facade based on at least length and height measures of the facade. Finally, the method defines a number of scaffold levels depending on the height of the facade.
Background of the Invention
The Japanese patent application, JP 11141115 A2, relates to the realizing of a highly reliable estimation process and to objectively verifying of the basis of estimates, estimate history and the results of estimate by estimating material costs and construction costs based on the quantities of materials by computer processing:
Different kinds of temporary scaffoldings hierarchically classifying the construction works in a specifying manner are selectively applied in step 1. Next, specifications or constructing conditions for selected temporary scaffoldings are set and applied in step 2 and arithmetically processed, and the kinds of materials and their quantity 3 are de- termined. Next, the materials and construction costs for the relevant work are estimated in step 6 based on a material unit price data file 4 and a percentage calculation table data file 5. In succession, labour cost, material cost, material weight, list by material, heaped capacity, time schedule and temporary facility area are respectively edited, displayed and output in step 7. As required a part of numerical data is transmitted as an input source for preparing scaffolding drawings by CAD 9. This way, a highly reliable estimation process can be realized. There exist several systems that can create drawings of a scaffold and counts all the components automatically for you in a fraction of the time it would take to do manually. These systems apply computer aided design software packages. Moreover, these drawings may contain boards, braces, handrails and by using this information it is possible to calculate component quantity lists as well as labor estimates and truck allocations. These scaffold systems can be designed to work with all modular and frame scaffold systems, including popular scaffolding systems already available on the marked. These scaffold planning tools can be used for many applications. However, they are all short of one important option, which is to calculate the static load of the scaffold.
Japanese Patent Application No. 11-346231 describes a method being able to create easily the temporary material plot plan side by side of an elevation surface by assigning scaffold materials to the elevation of a building automatically, even if software is operating as two-dimensional CAD, the temporary material plot plan side listing device and record medium which can create a scaffold drawing efficiently are offered by making top view data and elevation data correspond. Means for Solution is judges whether the top view, where the scaffold arrangement appearance datum line was plotted, is used for scaffold drawing creation. The datum-line point in an elevation is computed. The stanchion location by the side of an elevation surface is computed by making the stanchion location which was able to be found with the top view correspond to an elevation.
Object of the Invention It is the object of the invention to perform automatic static calculations, related to a scaffold model, based on rules and standards and in combination with input data related to an actual scaffold.
Description of the Invention The invention can be realized according to the method described in the preamble of claim 1 , if the computer means also perform static calculations based on input data and standard requirements for scaffolding. The computer means calculate the scaffold model and illustrate the scaffold model output means, which model is manually adapted before ending the calculation.
Hence, a scaffold model is calculated, and the computer can show a model of this scaffold e.g. on a computer screen, where the model can be rotated and seen from different angles. By hotkey, an information dialog will appear at this stage, giving the exact name, dimension, weight and article number of every single component mounted on the scaffold. Subsequent to computer calculation the computer means may manually adjust parameters in the scaffold. Entrances or gates can appear from the model shown on the computer screen, and a re-calculation of static values can be performed after performing corrections. Subsequent to calculating the computer may perform the static calculations and a total calculation of the number of components used in the actual scaffold. Furthermore, the computer means may define a cost of material and perform a price calculation both for renting a scaffold and for erecting and re-erecting a scaffold after use. This way the new method for computer calculation can efficiently generate all necessary data for erecting a scaffold along a building facade, where all statistic calculations are performed before placing the scaffold. The static and dynamic calculation is extremely useful and indispensable. The present in- vention offers an excellent solution to this problem. The invention provides an automatic scaffold planning based on recognition of structures and terrain. Furthermore, the type of automatic scaffold planning can be determined by settings entered by the user or by other means. Manual alterations are possible.
It is preferred that input to the computer means can be based on existing CAD data describing the object. Hence, the program calculating the scaffold can process existing data concerning the necessary measurement of e.g. a building. No further input data is necessary to perform the calculation of the scaffold when the CAD data is used as input.
Alternative input to the computer means can be downloaded images, which images are converted into a predefined format and where an informative part of the image is selected, where an orthogonal function corrects the image so that it becomes identical to the imaginary film plane, where at least one data set is added defining a measured distance at the image. Hence, it is achieved that when no CAD data exists, input to the computer system is created by downloading an image of e.g. a building facade. It is preferred to have more input than just an image to obtain the correct size. At least one measured value must be added to the image to actually calculate.
The computer means can perform a load calculation, depending on a defined scaffold maximum load. By defining a maximum load factor for the scaffold and in the computer program define the load placement on the scaffold it is possible for the load to be part of the scaffold static calculations. A high scaffold load can be necessary when dealing with concrete or bricks, as these materials are extremely heavy. On the other hand when dealing with light materials the scaffold load can be limited. By means of different load categories the person operating the computer may define the correct scaffold load.
The computer means can perform dynamic load calculation. Herby can movement or change of loads be part of the calculation.
Static and dynamic calculations are performed for all nodes in the scaffold. Herby is the maximal load calculated in every mechanical junction between scaffold components.
The computer means can also calculate wind loads on a scaffold, since wind forces can have a great dynamic impact on a scaffold. The calculation depends on the scaf- fold site of appliance and on which side of a building the scaffold is placed. By defining maximum wind speed the program can calculate the optimum scaffold, which can handle winds at maximum wind speed. The maximum wind speed differs depending on the scaffold placement either near the shore or onshore. Thus, scaffolds can be constructed differently depending on where they are to be used. To define the cheapest possible scaffold it is necessary to apply wind data to calculate the scaffold.
The computer means can perform a terrain calculation depending on data describing terrain characteristics. The computer means can perform a calculation of a climatic shielding. Furthermore, the computer means may calculate the climatic shield for a scaffold upper part only. As the climatic shield also has an impact on the static calculations, it is necessary to re-calculate after defining a climatic shielding on the entire scaffold or on part of a scaffold.
Furthermore, the computer means can perform a calculation of gates. Many scaffolds are to be left open around gates. Thus, the computer program allows for placing gates everywhere in the scaffold and to perform special openings e.g. around windows if necessary. To perform a static calculation special components to carry the weight of the scaffold are necessary, which components are to be placed above the gates so that the structure of the scaffold above the gate can carry the same load as the rest of the scaffold.
Moreover, the computer means can perform anchor calculations. The computer means also perform a calculation of the number of anchors, which are to be placed e.g. on a building facade to support the scaffold. As anchors often have to be placed in holes in the building, it is preferred to limit the number of anchors. Thus, a correct static calcu- lation of the number of necessary anchors can reduce the number of anchors actually used.
Finally, the computer means can perform a diagonal calculation. Thus, diagonals are calculated as part of the static calculations. The program allows for changes in the placement of the diagonals before finishing the design of a scaffold. Diagonals are calculated per default according to the stated rules about diagonal pattern for a specific scaffolding system.
The computer means can perform a number of other steps. E.g. it is possible to let the computer systems calculate the number of sections and to calculate the static load where an electric hoist is used. Latter' s can be placed in the computer model of the scaffold so there will be an ideal combination of latter' s on the actual scaffold. The computer system can also calculate fitted bay deck, which overlaps other decks with 20 centimetres.
Detailed Description of the Invention Fig 1 shows a scaffold designed I a few seconds by a system as here after described.
The method and the system concern a number of modules where the plan module is one of Projects modules, where the user has an opportunity to make different modifications with facade (scaffold system). On plan drawing user can see only view from above and also by using Change level menu view from above for every separate level of scaffold/scaffold system. In this module user can work with facades that are already generated around the building or create separate facade/facade system.
1. Add facade
Fig.2
1. To add a facade user should use Tools menu ("New facade"), the window names as New facade, the length measure is the wall length, and the height is the desired standing height for scaffold.
2. The user can choose how many degrees the building is when he adds the facade.
3. The user adds facade by dragging it from the 'Add Simple facade' drag point located on tab 'New facade'
4. Also it is possible to choose special facade ("Advanced facade" in 'Facade properties' (F4)) in which there are all possible combinations of sections for facade with chosen length.
5. If the wanted facade length cannot be reached by using the sections chosen by user (in F4 properties), then a dialog must be prompted with choice of the nearest length measurements of new facade: 'You cannot reach the wanted length by using the chosen section length! Please select new facade length'. If user choose section length 3m and facade length 25m, in dialog add buttons '24 m' and '27 m' and 'CANCEL'- for user to select between (24 and 27 m are the closest measurements below or above 25 m, which can be divided with section length 3 m). If press '24 m' or '27 m', then new facade is created with the selected facade length. If press 'CANCEL' button, then do not create fa- cade. (User must reconsider, which section lengths he wants to use)
2. Rotate faςade
1. There are the fixed (the most used) angles (0, 45, 90,135,180, 225, 270 and 315 degrees) in right mouse menu. By click on facade and choose defined de- gree facade is rotated at it.
2. In right mode there is also "Optional degrees", in case the user needs to rotate the facade in other angles.
3. If a facade is grouped with another facade, they will stay grouped.
4. During rotating one facade it can't overlap another facade. 5. The intervals of rotating vary at the different scaffolding systems.
6. If user set exact degree by himself in degree window, then there is a limitation to input degree. It is only possible to input degree from 0 - 359°. Otherwise a message for user appears: 'You must set a degree from 1-360°, please re-enter degree'. 7. It must be possible to let user to delete degree in window degree (so that it empty). In that case facade stays in initial position, as user make no changes with it.
8. It is possible for user to enter degree with one decimal (for ex. 22.5°).
9. Every time user chooses some degree for rotating, drawing is updated. 10. Close rotate optional window automatically, when removing the facade.
3. Walk through frame
3.0.1 Can be added on plan and elevation 3.0.2 Is added by right mouse menu (item "Walk through frame")
3.0.3 Remove Walk through frame - option in popup menu. 3.0.4 When WTF is added then facade height can be changed, but 0 level cannot be less then 2m. 3.0.5 If walk through frame is removed then facade height is returned to initial.
3.0.6 Walk through frame is added for the whole facade in 0 levels.
3.0.7 Guard rails in 0 level are visible if track bar points is set at 'All' and '0' level. 3.0.8 The height of level becomes higher for 0.25m (the total height is 2.25m).
3.0.9 The highest WTF level can be up to 2.50m. Not more. 3.0.10 On plan there is an icon connected to facade (old version) 3.0.11 Can be added if the width of scaffold is not wider then 1.75m (for post system). For frame systems the width of scaffold can not be changed. 3.0.12 There can be several WTF widths. User can choose one of them.
3.0.13 There are inside and outside guard rails all over the level (but also it must be put as parameter in setup: Guard rails from the both sides) 3.0.14 No end guard rails.
3.0.15 It is not possible to add bracket/cantilever to the level with walk through frame
3.0.16 Anchors should be fastened to the basis scaffold at walk through frame level.
3.0.17 It's not possible to add decks in 0 levels if walk through frame is added. 3.0.18 If there is a section with dimension that cannot be closed by default deck type lengths/width and there are no other deck types, we need to place fitted bay deck on WTF to close a gap (just put a deck on 2 neighbor decks). This is for all systems. 3.0.19 If user choose only 3m and Im posts, then system must construct WTF level using Im posts connected together. So that we can reach 2m height in WTF level.
3.0.20 If height of facade is 11, 13 etch then it is possible to change height of level up to 1, 2.5, 3m. 3.0.21 It is possible to increase total height of facade for Im or just ask user about height changes and give him the closes available measurements. 3.0.22 In level above the WTF guard rails and toe boards must be present, even if the level height is less then 2m but not less then Im (including Im). 3.1 +8 WALK-THROUGH BOTTOM FRAME 1,40m 3 DESCRIPTION:
In Denmark, +8 has produced a Walk-through frame in width 1, 40 m, in co-operation with the customers. In fact, it has come to our knowledge, that a Walk-through frame 1 ,75 m, is not used in Denmark.
If the scaffold is built from the outside (Standards/frame are mounted in tubes in top of Walk-through frame - in left and middle tube), then it's possible to mount a bracket 0,70 inside.
NOTE: This Walk-through bottom frame component has no AVS in middle. As illustrated on drawing on page 1, component contains a tube in the middle for mounting Standard/frame on.
Decks mounted on top of WTF
Most of the scaffolding companies using +8 system, have decks in width 0,64 m available. So, 2 decks in size 0,64m shall be mounted on top of the upper cross tube for protecting the pedestrians walking through below.
Fig.4
NOTE: It's common to place veneer plates upon the decks on WTF, to make sure that all holes (space between the decks) are covered. And 0 level in this case is 2m in height (not 2.25m as with 1.75 WTF)
Access to basic scaffold
It can be quite problematic to access scaffold, if WTF present. The ladder cannot be placed inside of the WTF because of the pedestrians. And from the outside, it can also be problematic because of the traffic.
Most commonly a loose ladder is placed on the ground at the end of the basic scaffold, to get access. And normal access decks/ladders are placed as usual all the way up on scaffold. In setup user must have the opportunity to choose inside guard rails placed in walk through frame (some kind of parameter must be placed like check box).
If there is a deck level above WTF 3m in height (this is maximum) and user wants to add access deck in column or to this section, and of course in Setup we have ladders only for 2m in height and 2.5m in height then the access column must be stopped before going down through the WTF.
3.2 Combinations
3.2.1 Walk through frame/gate
It is possible to add walk through frame and gate to the facade. In this case walk through frame is divided in parts so that it is possible to reach gates, if it is needed.
3.2.2 Walk through frame/ladder
No ladders in 0 level if walk through frame is added.
3.2.3 Walk through frame/UTV
In post system we connect UTV and basis deck with horizontals of the most suitable length and connect then to the couplers of the UTV posts at access levels, then place decks on horizontals so that we have one more normal section between basic scaffold and UTV (in this case decks will be leying).
3.2.4 In frame system we use brackets of suitable width and then connect them with tubes by couplers (swivel couplers) from the both sides. But before add UTV/ WTF ask user where he wants to have access to the UTV: in top or in all levels?
3.2.5 It is necessary to place cantilevers in all levels (except 0) in section where UTV is placed to connect UTV decks with central decks of facade.
3.2.6 Walk through frame/Terrain When adding WTF to facade, then choice of other width must be placed in menu.
3.2.7 It must be possible to 'Remove' WTF and if adding width 1.40, then width 1,75 should be available in menu also. 3.2.8 Decks above WTF
Decks should be placed in top of walk through frame to protect walking men from falling parts.
3.2.9 Walk through frame/bracket/ move facade If bracket is added to the section - do not do anything. If brackets are added to facade then we need to send user request about: move scaffold to outside of WTF, Move facade together with WTF, Leave facade like it is now, even if it intersects the building. If we have facades with bracket and then user adds WTF, the same variants must be available to the user about movement scaffold on the WTF.
Scaffold with brackets, and scaffold is moved away from the building so brackets don't intersect with the building. Fig. 5
Adding WTF Choose one of the following options for adding WTF on the facade with brackets: ■Basic scaffold on the inside of WFT: Fig. 6
Basic scaffold on the outside of WFT: fig. 7
■ Basic scaffold on the inside of WTF - distance between WTF and the building equals 0.30m even though brackets may intersect with it: Fig. 8
3.2.10 WTF/ section width When WTF is added to facade, it should be impossible to change section width.
If a user wants to do so in this case, he should add cantilevers to widen the scaffold area. Menu 'Section»Section Width' should be disabled.
3.2.11 10. WTF/Protection fan. If User adds to facade walk through frame then add protection fan: it must be at least 1 level between them. So that when user add walk through frame, protection fan must be automatically moved up (not removed).
3.2.12 11. WTF/ cantilever If user adds cantilever to the level and then add WTF, in case when cantilever and WTF components intersect each other system must prompt a dialog about moving cantilever up or remove cantilever. If user chooses cancel then WTF is not added. If other component is placed above the cantilever and it is not possi- bly to move it up, then system must tell user that it is not possible to move cantilever up and give a choice to remove cantilever or not to place WTF. If WTF was added and then user wants to add cantilever in level where components will intersect each other then system must prompt a dialog to user that it is not possible to add cantilever to the level.
3.3 UTV / Walk through frame fig. 9
3.4 WTF width In Setup we must have parameter 'Walk through frame width' where user is able to choose the width of WTF that will be used by default. In F4 properties menu it must be possible to change the Walk through frame width to desirable (on advanced tab). 3.4.1 Grouping facades with WTF fig. 10
If facades are grouped with each other then WTF can not be added in such cases as
3.5 WTF for Bosta70
The WTF 155cm has two functions:
You can place one 74cm frame or 101cm frame, so if you want too move 74cm frame from inside to outside then you need to reverse the position on the frame.
3.5.1 WTF facade for frame systems
Normally we generate facade 30cm lower then wall. If we add WTF after facade is generated, then the height changes and the limit is violated. It is acceptable to give user opportunity to choose between lower and higher facade height. For example in Bosta70 if facade with height 9.30m was generated, then user adds WTF. The height of WTF is 2.18m., the maximum allowable base jack height is 26cm. So we get that bottom level height is 2.18+26=2.44m. The next level is 2m frame + 0.66m frame = 5.10 m height. The next level is 2m, so we get height in 7.10m. The next level is also 2m, so we get 9.10m. This height is minimum acceptable in this case. The same way system counts the other suggested variant that is a little bit higher.
3.6 WTF for AlIr ound system For Allround system there are 2 types of components for WTF: double horizontal and WTF in DB. And by menu we need possibility to choose between Double Horizontal and Walk through frame component. User must be able to choose between these to components when he wants to add WTF to Allround facade. So when user choose WTF item in menu a request must be send for him: "What component you want to use as WTF?" and choice between available in system. If you should build basic scaffold of 0,73 or 1.09 on top of it, then mount Allround AVS component for U profile on top of it, and continue upwards with standards. Fig. 11
If user chooses WTF component, then it is possible to build 0.73m and 1.57m. If user wants to use U-profile in 1.09 (basis scaffold width is 1.088m) then Starter component must be placed in hole of WTF component and post mounted in it as well. Fig. 12
4. Gable 4.0.1 When add gable to facade then icon connected to facade appears (in old version) 4.0.2 Gable is drawn on building, only after this facade can be generated with gable.
4.0.3 Adding of gable is available on Elevation 4.0.4 This icon have following properties: a) Gable height or roof degree (user can set only one parameter in this case, the other must be set as zero) b) Gable centre c) Foot of the roof d) And also left and right length and height setup.
Every time user edit gable properties, parameters must be set as user set them before (default values are set if add/edit gable first time). 4.0.5 There are 4 different types of gable (single, left, right and common) 4.0.6 Minimum gable height starts from 0, maximum - there is no limit. 4.0.7 There is a screen near the gable setup where user can see a gable scheme and see the way it is modified during parameters changing. During modification of gable outline must fit to window size. 4.0.8 Gable properties window appears by right click on gable icon (old version).
4.0.9 On elevation, measure line shows the height of facade with added gable (facade height + gable height (including foot of the roof)). Every time gable height is changed, the height of wall is updated. 4.0.10 Remove gable by right mouse click on facade, item "Remove gable".
4.0.11 Stable limit for removing section is 30sm. I distance up/left/right is more then 30sm, then section must be placed.
4.0.12 If facade with gable is not grouped to the other facade and there are sections in gable area that are not removed (that overlap some part of gable) then inside guard rail must be placed. It is placed by using AVS component from the max distance between gable and guard rail of 30 sm. to protect scaffolder from falling down (for post system). For frame system we use safe clamp or rigid coupler.
4.0.13 If gable is placed then for user it is necessary to set a parameter which is for setting a max length for removing sections.
4.0.14 Gable can be much higher then scaffold height. 4.1. Gable/cantilever in top of facade
If there is a facade with cantilever in top level and user adds gable then all levels in gable area must be covered with cantilever (if it was added at height of 10m then from this height up to top of gable cantilever must be placed).
And if user remove gable in this case then facade must be in initial state - it must be in cantilever in top level, (was possible in old version) 4.1.1. Gable/ cantilever in F4 properties menu
1) According to the settings in F4 properties menu, cantilever by default is placed only in top level.
In this case facade with gable has cantilever only in top level (and it does not depend on the gable type) 2) According to the settings in F4 properties menu, cantilever by default is added to the all levels.
In this case cantilevers are added to the all facade levels (with gable levels if gable is present). Note: In future user must be able to choose where cantilever is placed by default
(in top level only or in all levels)
4.2. Facade with climate shield (shielding)/add gable
If user add climate shield/shielding to the facade, then all levels that include top sections must be covered with climate shield. If we have facade with climate shield/shielding and gable Then all gable sections must be covered with climate shield/shielding.
4.3. Gable/electric hoist
If add gable to facade and after that add electric hoist to the top middle section, then electric hoist is added above top section of facade with gable. So that it is highest top section in facade.
If electric hoist is added to the top section and not in the middle then after adding gable it must be the highest point of the scaffold (old version). It is possible to add electric hoist to any top sections in gable. Of course if other components won't conflict.
Example of building with gable and facade calculation. Fig. 13 and 14
5. UTV (Universal Tower Version)
5. UTV (Universal Tower Version)
5.0.1 The UTV is the same height as the scaffold by default, and is for all sections vertically.
5.0.2 When placing UTV, it can be added to a column only. 5.0.3 There are two types of UTV: UT V Tower and UT V Deck.
5.0.4 UTV Tower is a free standing section that can have any width depending on stairway length. 5.0.5 UTV deck cannot be linked to a section which is smaller or wider. It can be linked to a section that has the same width. 5.0.6 UTV can be fastened to cantilever (in top or in all levels) which is added to the section. If user remove cantilever then UTV must be fastened to the ba- sis scaffold.
5.0.7 The length of UTV can be changed. It depends on the stairway of the UTV. 5.0.8 Guardrails must be added for stabilization at every 2 m at each side of
UTV - and in same level as basic scaffold. Fig. 15 5.0.9 The height of UTV is defined by the height to UTV top deck. 5.0.10 By right clicking on the UTV, the user can set properties (height, tower/deck) fig. 16
5.0.11 We have 3 standard components for +8 available, stairway ladders, and they are: 1) Stairway Ladder - height 0.50 m - weight 7.80 - Component name: ATR50,
300294
2) Stairway Ladder - height 1.00 m - weight 10.50 - Component name: ATRlOO, 300295
3) Stairway Ladder - height 1.50 m - weight 17.50 - Component name: ATR150, 300296
UTV design (see Lene's letter 29.06.2005)
UTV for frame systems is a separate section and for post systems it is fastened to the post of facade
5.0.12 UTV properties are called by right mouse click on it. 5.0.13 UTV on plan
Fields: a) Height in metres (by default the same as facade height) b) UTV Tower (type of UTV) c) UTV Access-deck (type of UTV) d) Guard rail in top or Guard rail in all levels
5.0.14 Every time UTV height is changed on elevation (user adds/removes section) in properties menu height must be updated. 5.0.15 If user changes height in UTV properties, then on elevation tab drawing of
UTV section must be updated.
5.0.16 To protect scaffolder from falling down we need to place AVS on horizontal and connect AVS post with UTV post with guard rail. If section is wider then UTV tower length, we connect end post of UTV with basis section post and if there is no appropriate length of guard rail we connect it by GRFK.
5.0.17 Finally won't make anything in the bottom level (0 level) if there is less than 20 cm between the start of the stair and the ground. Just leave it on the ground and scaffold company find an manual solution about if is necessary.
5.0.18 If scaffold is used as Top lifted, then do not ask about access in all sections. Access must be in top only. If there are several levels in scaffold but they are 5.1. UTV for +8 frame system
UTV must be connected to the basis scaffold with couplers. Remove inside base jacks on UTV frames. Connect frames with couplers for each 2m. System must check if you have a component under the reference for AVS and it is also necessary to check if you horizontal and post or top post. If you missing some of this component you need to make it with tube and couples instead.
5.2. Combinations:
5.2.1. UTV/Cantilever
It is not possible to add cantilever before UTV section because of components inter- section. But it is possible to add cantilever after UTV section, if UTV is smaller then section length. Fig. 18
When cantilever and UTV is added to facade in same section, then we need following functionality: System must prompt dialog for user: 'Do you want to have access all levels of facade?' l: IfNO. Then system must close the inside of UTV with guardrails to prevent the worker of falling out (in all levels up to the top). Add inside guardrails in UTV length in reference to the various scaffold systems.
2: IfYES (POST SYSTEM) Then system must place cantilevers the whole way down.
Now UTV section must behave as usual, regarding guard rails, and placement of AVS on the outside of new section - so access is possible from UTV. NOTE: In general, do not place horizontal + AVS on the inside of UTV in level 0. (Is illustrated on fig. 19 and 20)
3: IfYES (FRAME SYSTEM) then same principle as for post systems for adding section with deck/decks between UTV and basic scaffold but place brackets in each level up to the level below the first added cantilever - in reference to the various FRAME SYSTEMS. Place decks in can- tilever bracket in same width as the cantilever section in top.
If UTV does not fit to size of section then posts from the left side must be connected with couplers each 2m. Other side of UTV must be connected with tubes every 4 m from the bottom.
5.2.2. UTV / Walk through frame In post system we connect UTV and basis deck with horizontals of the most suitable length and connect then to the cups of the UTV posts at access levels, and place decks on horizontals so that we have one more normal section between basic scaffold and UTV.
In frame system we use brackets of suitable width and then connect them with tubes by couplers (swivel couplers) from the both sides. Tubes are added each 4 m in height (each 2 levels from bottom). And before adding the UTV to the walk through frame we ask user about where he wants the access to UTV: in all levels or only in top? If WTF and cantilever is added to facade and the length of cantilever + scaffold width is less then we need to reach WTF, cantilever of smaller width is replaced with cantilever of the most suitable width. If we have WTF and user chooses to add UTV deck with access only in top level, then system must send request about in this case we can only place UTV tower. Otherwise if user chooses to have access in all levels from UTV deck, it is possible to do.
5.2.3. UTVAVTF for +8 frame system The only way to solve this construction, is to use a Horizontal to connect basic scaffold and UTV.
(Note. In the scaffold business, when they have +8 frame system, then they often also have post components, if they need to build special constructions.) In this case, we can only add UTV to frame system with WTF 1,75, if user have a horizontal H125 in his assortment. System must tell user, that he can't connect a UTV, if no H 125 is present. Fig. 21
5.2.4. UTV / Protection fan
IfUTV is added then it is not possible to add protection fan.
5.2.5. UTV / Climate shield
When UTV and Climate Shield is added to facade at the same time, in top section, where UTV is placed, the climate shield must cover the top of UTV section also. Fig. 22 and 23
5.2.6. UTV/shielding
If UTV and shielding is placed to the section, then shielding must cover only space where guard rail are placed to let scaffolder go through the central deck and UTV. 5.2.7. UTV/Electric hoist
It is not possible to add UTV and electric hoist to the same section. So if one item is already added then item menu for the other must be disabled.
5.2.8. UTV/Terrain
Is possible to use, but it is necessary to include post length correction depending of terrain shape. And of course it is important to pay attention to stairway direction so that length must fit to the UTV start height, and UTV building begins from the appropriate direction.
5.2.9. UTV/ Rubbish chute It is not possible to add rubbish chute and UTV to the same section. If one of these items is added then the other must be disabled in menu. But it is possible to add rubbish chute in cantilever section after UTV, if UTV has not the same dimension as section has (For ex. If section is 3.5 and UTV is 2.5m then it is possible to add rubbish chute in cantilever section after UTV).
The solution below is for all post systems. Fig. 24 and 25
5.2.10. UTV/Change section length
A dialog must be prompted: 'You are about to change section length in a section with UTV, do you want to continue and remove UTV?'. If 'Yes', then section length will be changed and UTV will be removed, 'No' than UTV in original section will stay.
5.2.11. UT V/Fitted bay
IfUTV is added to the section then it is not possible to add fitted bay to outside of this section (not possible to add fitted bay to UTV directly). 5.2.12. UTV/access deck
There are conflicts, if UTV and access decks are added in same section. So if user adds UTV and then choose adding of access deck to the same section prompt dialog for user: You are about to add Access decks to a section which has UTV. Do you want to continue? And the other way around: if user has access decks in column and add UTV prompt a dialog 'you are about to add UTV to a section which has Access decks. Do you want to continue?
If user add UTV with access to top level only, and then add access decks, then do not prompt dialog. Add access decks to all levels below the top level per default. 5.3. UTV stairway length 1. +8 - 3m
2. BLITZ - 3m
3. BOSTA70 - 2.50m
4. ENHAK - 3m
5. FACADE - 2.50/3m 6. MODEX - 2.50m
7. MURER - 3m
8. RAM - 2m
9. UNIFORM - 2.5m 10. ALLROUND - 2.57/3.07m
5.4. UTV/top section
If user has facade with UTV of uneven height then it is necessary to:
1. Use GRGR fastening from the both sides. Fig. 26
5.5. UTV/top platform (not used) fig. 27
5.5.1 As shown on picture there is additional deck is placed outside the scaffold.
5.5.2 Bracket (not cantilever bracket) of 0.7m is fastened to place deck 0.6m. 5.5.3 AVS is placed to on horizontal, and Im post is placed to fasten guard rail.
5.5.4 Do not place deck if there is left stairway (on picture one level lower), there is an opportunity to reach level without additional construction.
5.6 UTV/guard rail placement fig. 28
5.7 UTV / Walk through frame fig. 29
5.8 UTV/safety gate If user adds UTV to the section, then if user chooses to add safety gate to the facade, safety gate must be added to all sections except UTV section. In UTV section safety gate item must be disabled. If user wants to add UTV to the section with safety gate then a dialog must be prompted for user with choice to remove safety gate or not. But in case if UTV section as narrower then section, then it must be possible for user to add shielding to his small part of section even if safety gate is added to the other sections in facade.
5.9 UTV deck for Allround system Fig. 30
5.10 UTV/Facade Blitz system fig. 31
5.10.1 UTV stairway for Layer system fig. 32 and 33
5.11 Basis rules for frame systems. Fig. 34 Start place tubes from the 2nd level (right side of UTV) and from the 3d level (left side of UTV). Repeat diagonal placement every 4 levels up. Place them in top of level. Couplers must be placed every 2m in top of frame to connect UTV frames to each other.
If section length is more then UTV length, inside guard rail between UTV and basis scaffold (from the right side of UTV) must be connected to UTV frame with 2 couplers, because there is nothing at inside of frame construction to connect guard rail to it.
When connect UTV to the scaffold, in bottom level inside base jacks of UTV frames must be removed and connected with couplers to each other in bottom of frames. When do this, in all levels up UTV is fastened to basis scaffold with couplers that are placed under each deck level. Also tubes must be placed to connect UTV frame to basis scaffold. If UTV is the same dimension as scaffold section, then tubes must be placed from the both sides of UTV at the same height. Tubes must be placed every 2m starting from bottom and connect to basis scaffold and inside UTV frame with 3 couplers. If UTV length not equal scaffold length, we must place end guard in area between UTV and basis scaffold, and fasten it with coupler to the basis scaffold frame. It is also possible to use one guard rail for closing UTV area and area between UTV Tower and basis scaffold.
In top level we need to place deck and 2 end frames for frame systems, also move guard rail to outside of UTV. (see fig.35 ).
5.12 UTV/ Cantilever / frame system
If there is Cantilever and UTV added to scaffold then
• Instead of cantilever component use Bracket component of the same width.
• If there is no Cantilever diagonal component Place tube outside of the GR in left/right side of cantilever section and fasten it with 2 couplers.
• If there is a cantilever diagonal component then it will not intersect GR of Cantilever section • If WTF is added to scaffold and bracket component has not enough width to complete construction (for ex. In +8 frame system max bracket width is 0.7, but max cantilever width is 1,25m) then it is only possible to add UTV to scaffold if normal brackets from the inside of scaffold are added (as a result basis scaffold jumps to the outside of WTF and UTV is added as to the normal scaffold).Fig. 36
5.13 UTV Deck for Bosta70 fig. 37
5.14.1 UTV Deck for Bosta70/ Cantilever in top
Twin railing post component must be removed
Cantilever component must be removed
Decks are placed on UTV deck frame
Place Bracket post in outside frame horn, so that in cantilever section the end GR is fastened. Fig. 38
5.14 UTV/ Move deck in section fig. 39
This is UTV added to the section, and user moves deck in section (make section less then 2m in height).
5.15 UTV/ level height more then 2m
If user use deck levels that are more then 2m in height then it is not possible to reach some levels because UTV stairway is maximum 2m in height.
The rule is:
If some level (except bottom level) has height more then 2m, for ex. 2.5m, we automatically add UTV together with cantilever column. The cantilever must be in width not less then width of UTV stairway.
Then replace guard rail in cantilever section with 2 horizontals, place End Guard rail at same height as it is in UTV section (also place toe board above the top horizontal in cantilever section). Change outside guard rail in UTV section into Inside guard rail to give access to the section.
On top horizontal in cantilever place one more UTV stairway of appropriate height so that user has access to the cantilever section and to the level. Fig. 40 and 41
If it is not possible to build access between UTV and cantilever (in case when we have level difference between cantilever on basis scaffold and UTV) then guard rail must be placed to close access from UTV and prevent scaffolder from falling down. This could happen if we have that cantilever GR is placed not against UTV stairway, but somewhere higher or lower, so that it is not possible for user to reach ladder in cantilever section.
6. Protection fan
6.0.1 Protection fan provides protection against falling objects.
6.0.2 If user adds protection fan then symbol in plan drawing appears, and in elevation side view there is a section with a protection fan. 6.0.3 Protection fan can be removed and added also from elevation side. 6.0.4 Can be used above a gate, door or in the whole facade length.
6.0.5 We add protection fan in a height higher or equal 3 metres (count height for protection fan deck). No less then 3m!
6.0.6 The width of protection fan can be about 1.50 metres out from building (and it's not depends on the width of cantilever (if it is added to facade). 6.0.7 If add terrain that is higher then 2m then protection fan is moved one level up. 6.0.8 If we have a facade height of 4 m, and terrain line goes higher up than 2 m, then it must not be possible to add protection fan.
6.0.9 To remove protection fan choose in right mouse item "Remove protection fan"
6.0.10 IfUTV is added then adding of protection fan is banned.
6.0.11 It is not possible to separate parts of protection fan component 6.0.12 If facade has gate then protection fan must go one level up, so that all protection fan sections can be fastened to posts/frames.
6.0.13 Cantilever must be placed at list one level up (if protection fan is in 2nd level then cantilever must be in 4th level). 6.0.14 If electric hoist and protection fan are added to facade then remove protection fan in section where electric hoist must be.
6.0.15 For frame system we need to fasten protection fan by couplers.
6.0.16 It is not possible to place protection fan if scaffold has sections of different width. 6.1. Combinations:
6.1.1 Adding Access-decks to basis scaffold does not affect Protection.
6.1.2 Adding Brackets does not affect Protection fan.
6.1.3 Cantilever can be added in a level from the Protection fan level i.e. if protection fan is added in Level 2, cantilevers can only be added in level 4 or above.
6.1.4 Adding Climate shield does not affect Protection fan.
6.1.5 Changing decks' measures or orientation does not affect protection fan.
6.1.6 Moving or removing decks in level does no affect protection fan. It stays in the same position. 6.1.7 Adding Diagonals does not affect Protection fan.
6.1.8 Adding Electric hoist: in this section protection fan must be removed.
6.1.9 When Fitted bay is added place fitted bay decks between protection fans at facades. But it is not possible to add fitted bay to the outside of Protection fan. 6.1.10 Adding Gable does not affect Protection fan.
6.1.11 When Gate is added, Protection fan adjusts to the gate height (so that it can be fastened from bottom) and is put up in all sections.
6.1.12 Guard rails does not affect Protection fan.
6.1.13 Adding H-diagonals does not affect Protection fan. 6.1.14 Adding Ladders does not affect Protection fan.
6.1.15 Protection fan + Net: If protection fan is added to the facade then net/plastic must be placed down to protection fan deck. 6.1.16 Protection fan + Plastic: If protection fan is added to the facade then net/plastic must be placed down to protection fan deck.
6.1.17 When rubbish chute is added then it is going outside the protection fan. Or place access deck instead of simple deck in protection fan so that rub- bish chute is going through protection fan deck.
6.1.18 Adding Shielding does not affect Protection fan.
6.1.19 It is not possible to add UTV and protection fan.
6.1.20 Between Walk through frame and Protection fan must be 1 level for post system and it is possible to place protection fan directly above WTF for frame systems. Fig. 42
6.1.21 When a section is appended, there is Protection fan in it.
6.1.22 Removing a section doesn't affect Protection fan.
6.1.23 Changing a section does not affect Protection fan.
6.1.24 If facade has terrain then must be no less or equal then 3m fro protection fan placement.
6.2. Protection fan for Bosta70
Consists of several parts: single guard rail (38150), bracket post for protection fan
(38224), deck bracket (92080), connection tube with couplers. In calculation report we also need to calculate Plank fastener component but don't show it in 3D drawing. Also calculate frame pin where bracket post and deck bracket are fastened. In bottom the protection fan is fastened with a half-coupler to the vertical frame. In top fasten it with bolt and nut. Single guard rail is fastened to the highest point of Bracket post component. We need to place 2 decks in 70 on deck bracket and one 70 cm and 1 deck in 30 cm on bracket post.
The designs of components see in Bosta70 datasheet, p. 9. Fig 43
6.3 Protection fan for grouped facades
7. Climate shield
7.0.1 There is a symbol of climate shield added in plan drawing. 7.0.2 At the elevation view all sections in top will be covered with climate shield (the sections are marked out with blue colour).
7.0.3 Climate shield can be added to the facade top level or to the section separately. 7.0.4 It is placed outside the section (guard rails and other parts of section are covered by climate shield.
7.0.5 For facade with gable (or just some sections are added in top of facade), if climate shield is added to the top sections then climate shield is just simply fastened to the neighbour posts (climate shield is simply bound to the posts by hand). So iron in top sections must be removed from the side which is connected to the post of facade. We have two irons from the both sides of section for example in top highest section for added gable.
7.0.6
7.0.7 In elevation view every section separately can be cover with climate shield.
7.0.8 It can only be added in top sections.
7.0.9 If user adds cantilever and/or bracket, then climate shield covers all space between building and scaffold and also cantilever and/or bracket.
7.0.10 If some sections are added to the top section then climate shield must cover all sections which were added and become as top now, section under this added, and sections from the left/right side of these top sections, so that all top was covered. Fig 44
7.0.11 To remove climate shield the option in popup menu is chosen. 7.0.12 Climate shield and shielding can be added to the same section or to the whole facade (it is possible to place them both at one time). 7.0.13 Climate shield can not be added to electric hoist section. 7.0.14 Climate shield can cover only cantilevers of the same width. 7.0.15 Climate shield is placed to cover all levels that contain top sections. For example if some section or simple gable is added, then all gable sections including the lowest top level are covered with climate shield. All top sections except electric hoist are covered with climate shield. 7.0.16 If scaffold is equal 0.7m or less then don't need to add standard/posts from inside. If scaffold is wider then we need to place these posts (see image below).
7.0.17 Climate shield can be added to the sections of different width. For this it is necessary to remove band (hook) from post between wider and narrower section and tie the climate shield to the posts. It necessary to bend a little bit climate shield band to equalize the level for climate shield placement. The angle can be changed by force of guard rails connection to the cups. Fig. 46
This standard/post is also called Support tube for climate shield. In database - reference 72.
7.1 Climate shield for +8 frame system
For +8 frame system we replace frames in top and place posts connected to frame horns. Other design is the same as for +8 posts. It is not possible to build Climate shield for +8 frame system if we have no additional posts available.
7.2 Climate shield combinations:
7.2.1 Adding Access-decks does not affect Climate shield.
7.2.2 Brackets in the top level are covered together with basis deck by the cli- mate shield.
7.2.3 Cantilevers in the top level are covered together with basis deck by the climate shield.
7.2.4 Removing, moving or changing decks' measures or orientation affect climate shield. Climate shield must cover the all components in section in- eluding new section dimension.
7.2.5 Diagonals in section are covered by climate shield.
7.2.6 Electric hoist section can not be covered with climate shield.
7.2.7 When Fitted bay is added, it is covered by the climate shield.
7.2.8 If Gable is added, all sections in the gable should be covered by Climate shield.
7.2.9 Adding Gate does not affect Climate shield.
7.2.10 Guard rails in section are covered with Climate shield.
7.2.11 Adding H-diagonals does not affect Climate shield. 7.2.12 Adding Ladders does not affect Climate shield.
7.2.13 Climate shield + Net: Net is started from the level under climate shield
7.2.14 Climate shield + Plastic: in 3D module it must be shown as join plastic from top 7.2.15 Adding Protection fan does not affect Climate shield.
7.2.16 If rubbish chute is in cantilever section then Climate shield cover cantilever section with rubbish chute.
7.2.17 If rubbish chute is not in cantilever section then climate shield cover rubbish chute starter around (just cut the whole in plastic) 7.2.18 Shielding is covered by Climate shield.
7.2.19 Adding Terrain does not affect Climate shield.
7.2.20 UTV and Climate shield - see SR002 (UTV/climate shield).
7.2.21 UTV without additional deck - start climate shield in
7.2.22 Adding Walk through frame does not affect Climate shield. 7.2.23 When a section is appended, there is Climate shield in it.
7.2.24 Removing a section doesn't affect Climate shield. It is removed together with the section.
7.2.25 Changing a section does not affect Climate shield. It changes together with the section. 7.2.26 Climate shield must cover fitted bay section between to facades
7.2.27 If facades are grouped, climate shield must cover corner between facades.
First of all move the guardrail on top to first cup in the left scaffold. Same procedure in the right one, but add one more in top to make structure in climate shield. About connecting those two together use tube and couples outside corners and in the top too. Fig 47
Facades in 90 degrees:
Connect with tubes and couples and remember to support the climate shield with sup- port tube on wide scaffold fig. 48
Facades in 0 degrees fig. 49 7.3 Climate shield component for Layer fig. 50
7.4 Climate shield components for Bosta70 fig. 51
It is possible to mount climate component, when we have bracket or cantilever.
We just extend the climate component by mounting a 48mm tube on it with a coupler in appropriate length, so it can cover the distance after the normal rules you describe below.
If bracket or cantilever is mounted, we must stabilize with a vertical tube on the inside of the frame of basic scaffold - like we do in other systems, when wide scaffold. Fig. 52.

If facade has gable or single sections added in top and user wants to add climate shield to the separate section, then see image below. Use tube for guard rail fastening. Use 2 couplers to fasten tube to the posts. Use 2 couplers to fasten guard rail to the tube. Fig. 53
7.6 Climate shield/wider level.
In this case cantilever of 1.09 for ex width is added. Fig.54
If climate shield added to the whole level fig. 55
If climate shield is added to the facade with brackets then we need prolongation of posts that are placed on brackets to hold the climate shield component. Fig. 56
7.6. Climate shield / cantilever for Enhak and Murer
This is for separate cantilever in top level. For cantilever one above another we use long post (we don't use cantilever component with bracket post). Fig. 57 7.7. Climate shield for grouped facades When 2 facades are grouped together additional plastic must be added to cover intersection between them. And also need to make a hole in plastic. Fig. 58
8. Cantilever
7. Climate shield
7.6.1 There is a symbol of climate shield added in plan drawing.
7.6.2 At the elevation view all sections in top will be covered with climate shield (the sections are marked out with blue colour). 7.6.3 Climate shield can be added to the facade top level or to the section separately.
7.6.4 It is placed outside the section (guard rails and other parts of section are covered by climate shield.
7.6.5 For facade with gable (or just some sections are added in top of facade), if climate shield is added to the top sections then climate shield is just simply fastened to the neighbour posts (climate shield is simply bound to the posts by hand). So iron in top sections must be removed from the side which is connected to the post of facade. We have two irons from the both sides of section for example in top highest section for added gable. 7.6.6
7.6.7 In elevation view every section separately can be cover with climate shield.
7.6.8 It can only be added in top sections.
7.6.9 If user adds cantilever and/or bracket, then climate shield covers all space between building and scaffold and also cantilever and/or bracket.
7.6.10 If some sections are added to the top section then climate shield must cover all sections which were added and become as top now, section under this added, and sections from the left/right side of these top sections, so that all top was covered. Fig. 59 7.6.11 To remove climate shield the option in popup menu is chosen.
7.6.12 Climate shield and shielding can be added to the same section or to the whole facade (it is possible to place them both at one time).
7.6.13 Climate shield can not be added to electric hoist section. 7.6.14 Climate shield can cover only cantilevers of the same width.
7.6.15 Climate shield is placed to cover all levels that contain top sections. For example if some section or simple gable is added, then all gable sections including the lowest top level are covered with climate shield. All top sec- tions except electric hoist are covered with climate shield.
7.6.16 If scaffold is equal 0.7m or less then don't need to add standard/posts from inside. If scaffold is wider then we need to place these posts (see image below).
7.6.17 Climate shield can be added to the sections of different width. For this it is necessary to remove band (hook) from post between wider and narrower section and tie the climate shield to the posts. It necessary to bend a little bit climate shield band to equalize the level for climate shield placement. The angle can be changed by force of guard rails connection to the cups. Fig. 61
This standard/post is also called Support tube for climate shield. In database - reference 72.
7.7 Climate shield for +8 frame system For +8 frame system we replace frames in top and place posts connected to frame horns. Other design is the same as for +8 post. It is not possible to build Climate shield for +8 frame system if we have no additional posts available.
7.8 Climate shield combinations:
7.8.1 Adding Access-decks does not affect Climate shield. 7.8.2 Brackets in the top level are covered together with basis deck by the climate shield.
7.8.3 Cantilevers in the top level are covered together with basis deck by the climate shield.
7.8.4 Removing, moving or changing decks' measures or orientation affect cli- mate shield. Climate shield must cover the all components in section including new section dimension.
7.8.5 Diagonals in section are covered by climate shield.
7.8.6 Electric hoist section can not be covered with climate shield. 7.8.7 When Fitted bay is added, it is covered by the climate shield.
7.8.8 If Gable is added, all sections in the gable should be covered by Climate shield.
7.8.9 Adding Gate does not affect Climate shield. 7.8.10 Guard rails in section are covered with Climate shield.
7.8.11 Adding H-diagonals does not affect Climate shield.
7.8.12 Adding Ladders does not affect Climate shield.
7.8.13 Climate shield + Net: Net is started from the level under climate shield
7.8.14 Climate shield + Plastic: in 3D module it must be shown as join plastic from top
7.8.15 Adding Protection fan does not affect Climate shield.
7.8.16 If rubbish chute is in cantilever section then Climate shield cover cantilever section with rubbish chute.
7.8.17 If rubbish chute is not in cantilever section then climate shield cover rub- bish chute starter around (just cut the whole in plastic)
7.8.18 Shielding is covered by Climate shield.
7.8.19 Adding Terrain does not affect Climate shield.
7.8.20 UTV and Climate shield - see SR002 (UTV/climate shield).
7.8.21 UTV without additional deck - start climate shield in 7.8.22 Adding Walk through frame does not affect Climate shield.
7.8.23 When a section is appended, there is Climate shield in it.
7.8.24 Removing a section doesn't affect Climate shield. It is removed together with the section.
7.8.25 Changing a section does not affect Climate shield. It changes together with the section.
7.8.26 Climate shield must cover fitted bay section between to facades
7.8.27 If facades are grouped, climate shield must cover corner between facades.
First of all move the guardrail on top to first cup in the left scaffold. Same procedure in the right one, but add one more in top to make structure in climate shield.
About connecting those two together use tube and couples outside corners and in the top too. Fig 62 Facades in 90 degrees:
Connect with tubes and couples and remember to support the climate shield with support tube on wide scaffold fig. 63
Facades in 0 degrees
Fig. 64
7.9 Climate shield component for Layer fig. 65
7.10 Climate shield components for Bosta70 fig. 66
It is possible to mount climate component, when we have bracket or cantilever. We just extend the climate component by mounting a 48mm tube on it with a coupler in appropriate length, so it can cover the distance after the normal rules you describe below.
If bracket or cantilever is mounted, we must stabilize with a vertical tube on the inside of the frame of basic scaffold - like we do in other systems, when wide scaffold.

7.11 Climate shield/ gable
If facade has gable or single sections added in top and user wants to add climate shield to the separate section, then see image below. Use tube for guard rail fastening. Use 2 couplers to fasten tube to the posts. Use 2 couplers to fasten guard rail to the tube. Fig. 68
7.12Climate shield/wider level. In this case cantilever of 1.09 for ex width is added. Fig 69
If climate shield added to the whole level Fig. 70 If climate shield is added to the facade with brackets then we need prolongation of posts that are placed on brackets to hold the climate shield component. Fig. 71
7.6. Climate shield / cantilever for Enhak and Murer This is for separate cantilever in top level (wrong drawing). For cantilever one above another we use long post (we don't use cantilever component with bracket post).Fig. 72
7.7. Climate shield for grouped facades When 2 facades are grouped together additional plastic must be added to cover intersection between them. And also need to make a hole in plastic. Fig. 73
9. Electric hoist
9.0.1 If user wants to add an electric hoist then he chooses the section electric hoist to be added.
9.0.2 Electric hoist is added to scaffold according to the settings in Setup module. 9.0.3 By using properties menu it is possible to change default settings of adding electric hoist. 9.0.4 When electric hoist is added then cantilever section is removed.
9.0.5 If there is no corresponding length of diagonal, then use tubes and fasten it with couplers to the posts/frames. 9.0.6 For frame system place 2m frames from the both sides and close them with end guard rails, place only outside diagonal. 9.0.7 If electric hoist does not use section, then only outside diagonal is placed for this section. If electric hoist is placed in end section then end diagonal is added also.
9.0.8 IfEH is in edge section then it has crosswise diagonals from outside. 9.0.9 We need to place diagonal in section to prolong the pattern of the diagonal in electric hoist section. In Edge sections we always have crosswise diagonals and that's why it is possible to prolongate the pattern. If there is no section in level under electric hoist and it is not possible to stabilize the section we just place crosswise diagonals in EH section 9.0.10 Electric hoist in section has inside, outside and end guardian rails.
9.0.11 It is added at top level of scaffold.
9.0.12 When electric hoist is placed in top level (not use separate section) a diagonals are added from outside and left sides (if it is end section). If not then only outside diagonal is placed.
9.0.13 If electric hoist is added then one post height (where component is placed) become equal 2m so that diagonals can be placed (see on picture).
9.0.14 The removal of diagonal is not possible but it is possible to change the type of diagonal (by default we add left type, so it can be changed to right or crosswise).
9.0.15 If the user chooses this option (electric hoist), then a symbol on a section that indicates an electric hoist is shown.
9.0.16 In right mouse menu Edit function is added.
9.0.17 It is also possible to edit electric hoist by right mouse click on icon. 9.0.18 This function and electric hoist symbol has following properties:
1) Setup together with the scaffolding (it use it in script to calculation price on electric hoist).
2) Use section (Electric hoist will be in top level in a separate section).
3) Number of movements (no limitation about this parameter). Number of movements can only be integer! Example 2 - 3 - 5. Number of movements of electric hoist means, how many times the workers will move electric hoist in a certain scaffolding project. (If we for example have 3 scaffold sides, and it will be necessary for the workers to move it 2 times for hoist of material etc.) Each time an electric hoist is moved, it will cost the customer xx amount of money, and therefore it will affect the calculation.
If electric hoist does not use section then outside posts of electric hoist section still are 2m in height.
9.0.19 In setup we need parameter that gives user the choice of placing electric hoist in left or right side of a section. We could call it 'Electric hoist location' - 'Left' / 'Right'.
9.0.20 It is not possible to add electric hoist to adjacent sections. If user wants to add electric hoist to the sections it is only possibly to do this in a section (in the next one). So that if user wants to add electric hoist after the section with already added one, system prompt a message: 'Impossibly to add Electric hoist in two adjacent sections'
9.1 Combinations:
9.1.1 If electric hoist is added and user change section length then electric hoist must stay in section and not depend of its length
9.1.2 It is not possible to add section above electric hoist.
9.1.3 It is not possible to add rubbish chute and electric hoist in one section. 9.1.4 Bracket can be added to electric hoist.
9.1.5 Not possible to add cantilever to electric hoist section.
9.1.6 Shielding can be added to electric hoist
9.1.7 If gable is added then electric hoist is placed in top of the gable automatically. 9.1.8 Climate shield can not be added to electric hoist.
9.1.9 If electric hoist use section and bracket is added to electric hoist then 4 posts are staying the same length (Im).
9.1.10 If electric hoist is added then section in protection fan is removed.
9.1.11 It is not possible to add cantilever to the electric hoist section down to ground. And if it is then cantilever can be added only to the other sections.
9.1.12 It is not possible to add UTV and electric hoist to the same section. So if one item is already added then item menu for the other must be disabled
9.1.13 It is possible to add access deck to electric hoist section. 9.2 Functional combinations: 9.2.2 It is possible to add access deck to Electric hoist section and in all levels down.
9.2.3 Bracket can be added to Electric hoist section.
9.2.4 Cantilever can not be added to Electric hoist.
9.2.5 Climate shield can not be added to electric hoist. 9.2.6 It is not possible to remove diagonal from electric hoist, is possible only to change type of it.
9.2.7 If facade has Gable then electric hoist can be added in any top section of gable 9.2.8 Electric hoist cannot be added in Gate area.
9.2.9 H-diagonals can be added to Electric hoist.
9.2.10 Ladder can be added to Electric hoist.
9.2.11 Not possible to add Net. 9.2.12 Not possible to add plastic.
9.2.13 Remove section of Protection fan where electric hoist is added.
9.2.14 rubbish chute cannot be added to the section with Electric hoist.
9.2.15 Shielding can be added to electric hoist.
9.2.16 Adding Terrain doesn't affect Electric hoist. 9.2.17 UTV and electric hoist can not be in the same section.
9.2.18 Walk through frame can not be added to facade with Electric hoist, prompt a dialog.
9.2.19 When a section is appended, it is added as usual with facade height.
9.2.20 Removing a section adjacent to the one with Electric hoist doesn't affect the Electric hoist.
9.2.21 Changing a section happens as usual.
10. Rubbish chute
10.0.1 The user when use this option should choose a section to which rubbish chute adds.
10.0.2 There is a symbol on a section that indicates a rubbish chute. 10.0.3 rubbish chute symbol setups together with scaffolding. 10.0.4 rubbish chute can be placed in cantilever section and outside of cantilever section. If no cantilever is placed on a facade, it is possible to add one with rubbish chute.
10.0.5 If user adds rubbish chute and then remove rubbish chute, shielding must be also removed in case if it was no shielding added to facade before rubbish chute is added.
10.0.6 Even if user has access deck to place rubbish chute in cantilever section then it must be a choice for him to add rubbish chute outside of cantilever section.
10.0.7 When cantilever in a section or on whole facade, and adding rubbish chute - then cantilever must stay. 10.0.8 If rubbish chute in cantilever section, then access deck must be placed to the outside of the section.
10.0.9 If there is a cantilever added to the section and user wants to add rubbish chute and no access section of suitable length is available, then it is possi- ble to add rubbish chute to the section, but it must hang outside of cantilever guard rail (the same as we do when add rubbish chute without cantilever section). lO.O.lOSolution for (cantilever + rubbish chute in cantilever section) is to use cantilever bracket 1,25m (UKK125/2), in which deck 0,60 + access deck 0,60 for rubbish chute can be placed. lO.O.HAccess deck with rubbish chute for +8 is 0,60m. (Because of Access Platform with ladder references). For other systems access deck width references for rubbish chute in section are used.
10.0.12It is not possible to change section length to less then access deck length if rubbish chute is in cantilever section. The length of access deck is available in Setup data.
10.0.13For different scaffold systems access deck in rubbish chute section can be of different width, so this parameter is set in Setup module (3rd part component list), where user is able to these deck types, used for rubbish chute cantilever section, because these components are in some cases special made components, which are not available in component manuals for the various systems. Keep deck drawing, as system draws it now on Plan and 3D.
10.0.14In rubbish chute properties must be parameters: - Setup together with scaffold
- Number of movements
- Use cantilever section checkbox
- Use Liner checkbox
All properties must be connected to scripter environment 10.0.14he diameter is 51,5 cm in the top and 41,5 cm in the bottom.
10.1 Combinations
10.1.1 It is not possible for user to add rubbish chute and electric hoist to the same section. 10.1.2 If rubbish chute is added to the section then shielding is placed in it automatically and it does not depend on if rubbish chute in cantilever or not in cantilever section.
10.1.3 If rubbish chute in cantilever section then climate shield covers both cantilever and central deck.
10.1.4 To section with rubbish chute can be placed fitted bay. If rubbish chute in cantilever section is placed both sides of fitted bay then fitted bay covers both central and cantilever section. And also shielding should be placed in fitted bay section. 10.1.5 It is not possible to place access deck and rubbish chute in the same section. If access deck is placed in this section menu add rubbish chute is disabled. And if rubbish chute is added then can't place access deck. 10.1.6 It is not possible to add rubbish chute and UTV to the same section. If one of this items is added then the other must be disabled in menu 10.1.7 If cantilever of 1.25m width is placed in top section then we need to place one more deck in rubbish chute section near access deck to reach 1.25, but access deck must be placed to out side of deck so that it is easier for scaffolder to throw out trash. 10.1.8 If rubbish chute is placed not in cantilever section then shielding can be added around tube starter. By default no shielding in this section. Fig
74

10.4.24 Changing a section next to the rubbish chute section does not affect rubbish chute.
10.4.25 If rubbish chute in cantilever section, then it is not possible to add can- tilevers all section down. If there are cantilevers in whole section down it is not possible to add rubbish chute to this section.
10.5 Rubbish chute outside of cantilever section combinations with other elements: 10.5.1 Even if user has access deck to place rubbish chute in cantilever section then it must be a choice for him to add rubbish chute outside of cantilever section.
10.5.2 Adding Access-decks in the section with Rubbish chute outside of cantilever section is impossible, it is possible only in case if scaffold con- sists from one section.
10.5.3 Adding Brackets does not affect Rubbish chute outside of cantilever section.
10.5.4 Climate shield cover cantilever section and rubbish chute outside of cantilever section (same way as climate shield cover rubbish chute not in cantilever section).
10.5.5 Changing decks' measures or orientation does not affect Rubbish chute outside of cantilever section. 10.5.6 If deck is removed then it is not possible to add rubbish chute outside of cantilever section because it is not possible to add cantilever to it.
10.5.7 Adding Diagonals does not affect Rubbish chute outside of cantilever section (It is not possible to add diagonals in top level anyway). 10.5.8 Adding Electric hoist is not possible in the section with Rubbish chute outside of cantilever section.
10.5.9 Adding Fitted bay does not affect Rubbish chute outside of cantilever section (but it is not possible to add rubbish chute to fitted bay section).
10.5.10 When Gable is added, Rubbish chute starts at top section in gable, no problem with outside placement.
10.5.11 Not possible to add Rubbish chute outside of cantilever section in gate area.

10.5.16 Rubbish chute + Plastic: cover rubbish chute only in case when parameter 'including top' is marked. Otherwise plastic will go under rubbish chute.
10.5.17 Protection fan has access deck so rubbish chute goes through it or rub- bish chute can bend round it.
10.5.18 When Rubbish chute is in cantilever section, it is already covered by Shielding. When it's outside of cantilever section, then Shielding goes around starter point.
10.5.19 Adding Terrain does not affect Rubbish chute outside of cantilever sec- tion.
10.5.20 Adding UTV is impossible to the section with Rubbish chute.
10.5.21 Adding Walk through frame does not affect Rubbish chute outside of cantilever section (it can go outside of walk through frame). 10.5.22 When a section is appended next to the section with Rubbish chute outside of cantilever section, it must be simple section.

Rubbish chute outside of cantilever section.
10.5.25 If rubbish chute outside of cantilever section, then it is possible to add cantilevers all sections down. If there are cantilevers in whole section down it is possible to add rubbish chute outside of cantilever section. 10.5.26 If in top level rubbish chute is added outside of the cantilever section and cantilever is 0.70m in width, then it is possible to add cantilever for ex. in the 1st level with width 1.25m because rubbish chute can bend round the rubbish chute.
11 Deck
11.0.1 Using this option, the user has the opportunity to change deck's orientation (in two directions: lengthwise and crosswise).
11.0.2 In bottom level the deck is placed if the height between ground (base jack) and deck level is more or equal Im. 11.0.3 In frame system we place single guard rail on lowest guard rail point in
0 level. 11.0.4 Requirement 'Facade Properties' - Listbox 'Deck'
We need to change 'Deck' listbox in Properties, where we have deck variants. All width variants of the different deck types, must be listed with checkbox for user to make his choice, which variants he prefers. "Change deck" function should also be present in PLAN. Both for 'Facade' and 'Section'. It should be possible to change deck: (when setting the level indicator) Whole facade
In a single section
In a whole section column
In a whole level in facade length System must read all existing width variants for each scaffolding system.
Example of listbox, Allround system: Fig 77
11.0.5 In lengthwise options user can change width of deck by decks of the same type.
11.0.6 The intervals of the decks depend on the scaffolding system.
11.0.7 To the deck 4 hooks are fastened. The width of hook is 2.5sm and 8.5 length for +8 scaffold system. And for fastening from the left right side
1A of hook is used, so that we have only 4.25sm for hooks length outside the deck.
11.0.8 By default if decks are placed in lengthwise direction system must place wider deck to inside of scaffold and narrow deck to outside of scaffold. The same if we have cantilever added to the section. If decks are placed in crosswise direction, then we start place wider decks begging from the left side of section if facade is placed in 0 degree.
11.0.9 It's only possible to change the deck widths into the same types of deck, the specific scaffold type has. 11.0.10 Each section can have different deck widths (only vertical post system).
11.0.11 All facades which are grouped with point grouping are checked for new positions.
11.0.12 In crosswise option the deck's length consists of number of decks with other type.
11.0.13 By content menu it must be possible to change the deck width lengthwise or crosswise in a single section, or in the whole facade.
11.0.14 All of the length and width that can be used are placed in setup settings and right mouse menu. This is an option to orientate the deck. 11.0.15 Deck direction can be chosen for the whole facade or section.
11.0.16 It is possible for user to change deck for initial width by popup menu
11.0.17 To remove deck there is an item in popup menu. 11.0.18 If deck is removed then it is not possible to add cantilever/bracket to this section or to the whole facade.
11.0.19 If bracket/cantilever is added to the facade/section then it's not possible to remove deck where bracket/cantilever is placed. If there is no deck, then it is not possible to add bracket/cantilever to the section.
11.0.20 If there is a combination of decks in facade then there is necessary to place widest deck to outside of facade. 11.0.21 To add deck there is an item in popup menu.
11.0.22 In Facade and Section content menu we need to add item 'deck combi- nations' - then user could change for ex. width 0.9m from 2x0,45 deck to 1x0,60 + 1x0,30 in that section, if he finds out he needs access decks. 11.0.23 In F4 properties menu user must be able to choose the direction of decks in scaffold (lengthwise / crosswise). 11.0.24 For post systems we are allowed to have space between decks max.
5 cm. For frame systems (for example Layer it is acceptable to have
7cm space).
11.1 Change deck width/move deck fig. 78
11.1.1 If section width is changed then post must be placed where sections form corner.
11.1.2 Basis deck is placed at level as other unmoved decks (see attached image)
11.1.3 To the deck which was moved horizontal beam is placed. 11.1.4 For accessing the wider section in other level Ladder with Ih is placed.
This ladder is also used when we have Im section in bottom level (from ground to first level).
11.1.5 Horizontal is placed to mount the ladder and AVS
11.1.6 To protect scaffolder from falling of Im height AVS is placed and AVS is added.
11.1.7 Guard rail is added at height of Im.
11.2 Change deck width / diagonal placement If in facade (for ex. +8, 10m in length) there is a middle section of 3.5m then posts are erected in both side of this section through up the scaffold, so that diagonals that are placed at left/right section can be fastened to the cups of post. And guard rail in 0 level are also fastened to the posts ( not connection to AVS). 11.3 Change deck width/ arc wall fig. 79
When arc construction, and we want to change one section width, then we must be able to change 'Section width' by menu with same measurements, as if we had straight facade. Section width measures 1,46 - 1,82 - 2,13 - 2,30 - 2,80 - 3,30 etc... (then we can mount components in sides of wider section which fits exact in measure). 11.4 Change deck width / access deck placement
If scaffold width is more then 0.7m, then several decks of different width are placed in section. We always place access deck at outside of scaffold so that scaffolder can easily reach the wall. But if there is a combination of decks of different width, then we need to place access deck only instead of deck with appropriate width. 11.5 Change deck width.
If in scaffold there is a section of wider width, then we place 3d post from the both sides of section even if they are end sections. So that, in menu there is a scaffold of basis width (for ex. 0.7m) plus different possible lengths (this is sum of basis scaffold width + horizontals length). And then we can implement in menu width for 3 posts combinations: 0,7 + 0,7 = 1,4m; 0,7 + 0,9 = 1,6m; 0,7 + 1,25 = 1,95...
11.6 F4 menu
In F4 properties menu Deck direction item must be added so that user can choose deck direction before scaffold building.
Deck design
Universal planks with flap (no ladder) +8 fig. 80
Universal plank with flap and ladder seen from underneath +8 fig. 81
Normal Universal hook planks. (Note the AIu frame around in the edge of the plank) +8 fig. 82 Measurement of flaps are:
Deck width 0,64: Flap size: L=77cm W=58,5cm
Deck width 0,60 Flap size: L=77cm W=53,5cm Fig. 83
Layher access decks with/without ladder; for now we should design them as +8 universal planks with flap, (they have the same brown texture)
For Bosta70 access deck design is like for +8 (brown surface), flap size is 60x60cm.
11.7 Deck combination
If we have component for ex. Bracket 0.50m in width and there is a possibility to place 2 decks in 19cm and 1x19cm + Ix32cm, the system must place 1x19 and
Ix32cm. We always place as few decks as possible to feel the width. If we have 2 combination that consists of two deck, system must choose those which has widest deck to close holes between decks.
12. Access deck 1. If user wants to place access deck, it is only possible to add access deck in sections defined by the scaffolding system.
2. Every time access deck placed, the normal deck is removed.
3. There can only be height of 2 metres between two access decks.
4. By adding an access deck, it is for all sections vertically, and if the trackbar is set, it is only for one section.
5. If access deck should be added to fitted bay section then system ask confirmation for user about placing such decks to fitted bay section.
6. Access deck and h-diagonal can not be placed in the same section.
7. If there is scaffold width that is more then 0.7m, system needs to use some combination of decks. And for example we use 0.9m width: system place decks of width 0.6 and 0.3m.
8. If there is a combination of decks in facade then there is necessary to place widest deck to outside of facade, so that scaffolder can easily reach wall. i. But if user chooses combination of decks 0.45mx2 or
0.45+0.3Om and wants to place access deck, then system must put available access deck and place a b 10 or 20 cm (what is suits the most) to place other deck to close the hole in facade. A dialog is prompted for user about. ii. If access deck is removed then the ladder that is related/connect to this access deck is removed too. iii. If access deck with lower classification must be placed in section, then system must prompt a dialog, asking if it is allowable to place it. Otherwise user must choose to place UTV. iv. User can place access column even if there is no decks v. For +8 system (according to new rules of scaffold construction) we do not remove outside guard rail in bottom level if access deck is placed in column. Keep outside guard rail. vi. Length measures for Allround and Facade ladders are: vii. Variant 2,15 - actual size = 2,20 viii. Variant 3,00 - actual size = 2,97 ix. And width of ladders is 35sm. x. If we choose the component for Bosta 70 'AIu ladder passage frame with ladder' then they cannot be separated. This is one join component. xi. Length measures for +8 ladder xii. For 2m section - 2,13m xiii. For 2.5m section - 3m xiv. Bosta70
If height not equal 2m, then for Bosta 70 there are ladders available to get access to 1st level - no matter which frame height is chosen in bottom or at other levels, there are ladders in length to reach the level above.
When a 2m ladder is placed in a 2m section height, it is placed in a certain angle, as your picture below.
If we have section height 1,50 (1st level for example), then the ladder is placed in same angle as if 2m section, and it should be possible to calculate the length this way. So we have frame heights 2m - 1,50m - 1,00m - 0,66m, and a ladder will always fit these section heights for Bosta 70. (the ladder is fastened to the frame tube, and does not go up through the hole in deck)
When placing ladder in 0 level a LADDER LOCK is placed for stabilization (to place the ladder on). See fig. 84.
xv. In manual access deck has width 0,70.. but exact measurement must be: Frame width is 0,74 from centre of tube to centre of the other tube. Diameter of tube is 4,8 cm.
0,74 - 4,8 = 69,2cm, which should be the exact width of deck. The exact length of Ladder 2m is 2,03m The exact width of ladder is 31 cm. b. Ladder in bottom level. First we need to check reference list. TL doc. i. If bottom section height is equal then 3m but more then 2m we put deck and ladder, but deck is placed only in this section (so that deck is placed only for ladder) and there is no outside guard rail for bottom section with ladder. ii. If height is more 0.5 m but less then 1.5m we place bracket component (0.6 or 0.7 width). This component is fastened to the highest guard rail fastening point. In the section to which bracket for such ladder is fastened, we need to place horizontal and guard rail post on AVS, use guard rail 1.75 for access sec- tion length (the access to the section must be not less then
50cm). For frame systems we use guard rail or bracket post and safe clamp that is fastened to the deck. For +8 frame system we place tube instead of horizontal (if parameter in Setup is not checked for horizontals in frame system). iii. If we can't place bracket with ladder (upper point of guard rail) then ladder must go through access deck in basis scaffold. This must be done if bottom level height is more then 1.5m. In this case we don't need to open the section and place horizontal and AVS component. iv. If ladder is placed in bottom level then outside GR must be removed (or if there is also diagonal in section it must be also re- moved). This is because deck in bottom section keeps the strength of structure. c. Check Access deck/ladder reference Fig. 85
For Heavy steel scaffold we use special Access deck component: Reference 71 - Ac- cess Transom. d. Replacement of access decks.
We now have functionality, that we by F4 properties have choice of 'Access decks with ladder' / 'Access decks without ladder'
But if user have almost finished his project, and finds out that he made wrong choice and want to replace his access decks, then he must start from scratch! Therefore we need functionality Access deck 'Properties' by right click menu:
Menu should now be like: 'Access decks' > 'Add' / 'Remove' / 'Properties'
By 'Properties' a small dialog window opens, and user can choose the other variant of access deck, than first chosen from F4 properties. It's not quite logical to have dialog box, when only one choice, but we might need this properties dialog in the future for other functionality. e. Diagonal pattern/access deck
If we have facade system that use diagonal pattern, then in bottom section where ladder is placed diagonal must be removed to give user access to ladder. This is for all systems. Fig. 86
14 Guard rail
14.0.1 There has to be outside guardian rails on every deck plus end guardian rails at the beginning and at the end of the scaffold. 14.0.2 When chooses this option, the user should define the section in which guardian rails will be removed or added.
14.0.3 If outside guard rail is removed in some section then we need to put end guard rails in this section to prevent scaffolder from falling down. 14.0.4 As default no guardrails inside, if bracket is added in one or more sections.
14.0.5 If the user adds cantilever there are also outside guardian rails.
14.0.6 If user adds guard rail then in menu there is a marked item "Manual". So this guard rail will not be removed automatically. 14.0.7 There is an option in popup menu "Check guard rails automatically". This item is used if user adds guard rails manually but then he wants to go back to the initial guard rails rules which are specified in system.
14.0.8 It is possible to remove guard rails which are added to facade by default.
14.0.9 It is possible to add guard rails everywhere user wants to do that. 14.0.10 It is possible to add guard rail where no guard rails are placed (inside/outside/left/right)
14.0.11 If guard rail is already placed it is not possible to add it one more time (so item Add in right mouse menu is disable).
14.0.12 If guard rail is removed (so there is nothing to remove) item Remove in menu must be disabled.
14.0.13 In bottom level normally we don't place guard rails, because above the base jacks we place horizontals.
14.0.14 For frame systems (Bosta70) we place single outside guard rail in bottom level in closest to base jack connection point. 14.0.15 Limit for adding guardrail in bottom level is 1 m. And then it's placed just below deck so if first level is in 0,50 m height, then do not add guardrail.
14.0.16 If the length of guard rail is more then fitting length between posts in section, then the couple is placed at post and to the guard rail so that it will be fastened from the outside of section at a little angle to post. 14.0.17 Inside guard rail is never used on fitted bay.
14.0.18 If we place and guard rail somewhere for ex. In UTV section (if UTV section is 3.07 and UTV is 2.57m) then we got that guard rail does not fit to the hole between them. So we need 1 coupler to connect guard rail to the facade (farm or post). This is for Facade, Allround, Bosta70. If we have +8 system then we need 2 couplers to connect guard rail.
14.0.19 If the distance for guard rail placement is equal or less then 15cm, it is acceptable not to place the guard rail. 14.0.20 If distance between scaffold (or part of the scaffold) and wall is more then
30cm then inside guard rail must be placed automatically.
Postpone the task about placement of guard rails if it is not possible to place bracket post in bracket component.
14.2 Guard rail shortening device (GRFK). Fig. 87 14.12.1Wide section in scaffold Basic scaffold width 0.70 m, wider section width
If no guardrail is available to close the ends normalize, then use GR in the length closest to, and just above the actual width measurement, as shown at fig. 88.
14.12.2Guard rail list in F4 properties menu
In F4 properties menu there is a list of available guard rails for every scaffold system (except +8 system because there is the only type of guard rail is used). There are sev- eral types of guard rails: single, double and horizontals. Horizontals are used only in post systems. By default we use double guard rail. So it is necessary to check references for double and single guard rail, if there is no component for double guard rail we use two singles guard rails but in post system we also can place two horizontals. 14.12.3Guard rail in 0 level. 14.12.3.1 Post system:
The corrections are following for +8 Post system:
1. In bottom level, we should only mount Guardrail (GR) on the outside of scaffold. And only in every 2ndsection, as illustrated.
2. In bottom level, mount horizontal INSIDE / LEFT SIDE / RIGHT SIDE of every 2nd section. DO NOT MOUNT END GUARDRAIL IN BOTTOM
LEVEL IN END SECTIONS.
3. Rule is, that end sections should always be stabilized this way. With outside GR, and horizontals left, right and inside.
When we have uneven numbers of sections, then rule is obvious. But if scaf- fold contains 4 sections, then section 1, 3 and 4 should be stabilized with GR and H components.
4. Per default use always double guardrails outside of scaffold in bottom. (Example: Create wall 10m high, and generate scaffold; only horizontals in bottom) Note: if Section width is different from basis scaffold widths (for ex. User change one section width to 2.5m) then we need to pace outside GRs (for stabilization) and it does not depend on the main rule.
14.12.3.2 Important rule for bottom guardrails: 1. In level 0, the lower point of bottom guardrail must not sit higher than 0,80 m from the ground. 2. The distance between the lowest point of guardrail in level 0, and the lowest point of guardrail in next level (level 1) must not exceed 2,80 m. Fig. 89
Place horizontal (reference 29) in first connection point above the base jack (to the first closest cup). In 0 level we place horizontals in inside, outside, ends and between sections.
14.12.3.3 Frame system:
We cannot know if customer who has +8 frame system, if he has horizontals available, so therefore we need to do following:
1. Rule is to place outside GR in every 2nd section, and always in the end sections. (As for post system). One guard rail must be placed to the lowest connection point to base jack. In bottom for now must be one guard rail (not 2 like in +8 post system) and it does not depend on the section height. 2. We need parameter, which gives user the choice of check/ uncheck, if he wants to use horizontals for stabilizing.
3. Caption for parameter should be: 'Level 0 structure':
4. Text should be: 'Use horizontals in level 0'
If user checks, then horizontals are added the same way as for +8 post system. Parameter must be in Setup and in F4 properties menu. Place this on Advanced tab (so it will be near the button where user can choose +8 frame system).
14.12.4Guard rail/access deck
Guard rail on AVS must be placed if the 1st level starts from the height of Im. Fig 90
14.12.5 Guard rail placement rule:
If we have distance between connection points for guard rail placement less then 30 cm, we don't place guard rail there! Fig. 91 14.12.6Guard rail for Facade (Layer system) Fig. 92
For Facade system in bottom level single guard rail is fastened to the top chord con- nection point (top point for guard rail fastening on frame)
14.12.7Guard rail types
For +8 and Allround it's very important, user must not have the possibility to build scaffold of tubes only. This construction is not strong enough. 14.12.4.1 +8
Post system
There are 3 components that can be used as guard rails in +8 system: double, horizontals and tubes.
1) Double guard rails Inside: double guard rails
End sides: double guard rails Bottom level: horizontals
If we choose double guard rails, we are allowed to use horizontals. If system can't find double guardrails, then system should tell user what other components are avail- able, and give him the opportunity to choose, what he prefers.
2) Horizontals
Outside, end sides and bottom level has horizontals in guard rails cups. Outside and end sides have 2 horizontals instead of one guard rail. Horizontals are fastened in post cups. 3) Tubes
Tubes are placed instead of guard rails and horizontals everywhere and use the same rule for placement as horizontals. For each tube we use 2 couplers for connection.
But remember that this rule is only for guard rail. That means that in bottom we still place horizontals for stabilization. Frame system
Use only double guard rails and tubes 1) Double guard rails
Outside: double guard rails End sides: double guard rails
In bottom level we place components according to the Bottom level construction rule. Please see requirement
Please note, do not place guardrails in 0,50 m and 1,00 m frames. 14.12.4.2 Guard rail for Bosta70
There are 2 types of guard rails: single and tubes.
1) Single guard rail
From outside we place 2 single guard rails in every section. From end sides in top we place twin railing post. From end sides not in top we place end guard rails (double guard rails). In bottom level we place one single guard rail in closest to base jack connection point.
We don't need to take into account end sides when we choose guard rail type because we are allowed to use double end guardrail and tubes, even if you have single guardrail in the rest of the scaffold. If for ex. user chooses single guard rail and system can't find end guard rail of appropriate length, system can automatically place two single guard rails from end sides (also including top).
2) Tubes
Tubes are placed instead of single guard rail. But in top from end sides we still use top frame component and not in top we use end guard rails (double). In bottom tubes instead of single guard rails must be placed.
If the system can't find end components of length we need it must place it must place other components with the priority: 1. Double guardrails, 2. Single guardrails, 3. Tubes. And they can be combined. 14.12.4.3 AlIr ound
Allround has the same guard rail types as +8 post system: double, horizontals and tubes.
See description +8 post system. 14.12.4.4 Facade (Blitz) There are single, double guard rails and tubes. 1) Single From outside two single guard rails are placed instead of one double. From the end sides in top there is a special top frame component. From the end sides not in top there are end guard rails.
I we can't find end or top end component then use Frame component 2,00m and close with double end guardrail. In other sections in top of scaffold, if we do not have top frame component usually used, then also here we use top frame 2,00m.
2) 2) Double
Double guard rails are placed from outside except 0 level. In bottom (0 level) we need to place single guard rail in highest connection point on frame for guard rail. 3) Tubes
Everything is with tubes.
14.12.5 Loose guard rail
Tubes cannot be loose. Loose guard rail is a guard rail that does not fit between frame/2 posts. So guard rail in fitted bay section is always loose. Two horizontals or single guard rails that are fastened with couplers because don't fit to the section size. Fig. 93.
Rule is: Guardrails are always considered as loose guardrails, when they do not fit exactly between 2 frames, posts or tubes.
14.12.6 Guard rail placement for BOSTA70 Fig. 94 15 Propping up for the scaffold
15.0.1 It must be possible to add extra vertical posts, for propping up the scaffold
(England). 15.0.2 The user must be able to drag a vertical post to a section. Then on the plan drawing, the user can place the vertical post out from the section. But only in the distance of the Horizontal / Guardian rail.
DRAW COMPONENT GRFK IN 3D
See fig. 95
2. Brackets in one section Scaffold width 0.70m, bracket width 0.40m a) Bracket width is 0.40 and no available guardrail in that length. b) Use Guardrail GR 0.70, and fasten it to the INSIDE OF THE INNER POST with component GRFK. c) Use End toe board length 0.70 and place it on the inside of the inner post. It is tied to the inner post with some kind of wire see fig. 96.
3. Wide section in scaffold Basic scaffold width 0.70 m, wider section width 1. If no guardrail is available to close the ends normalize, then use GR in the length closest to, and just above the actual width measurement, as shown on fig. 97.
15. Propping up for the scaffold
1. It must be possible to add extra vertical posts, for propping up the scaffold (England).
2. The user must be able to drag a vertical post to a section. Then on the plan drawing, the user can place the vertical post out from the section. But only in the distance of the Horizontal / Guardian rail.
16 Fitted bay
16.0.1 Fitted bay is basically used for reaching the wanted length of a facade, and is made by erecting a loose deck and guardrail, which overlaps existing decks on scaffold.
16.0.2 Fitted bay is placed between two scaffolds and fitted bay deck is placed on the decks from the both sides (it also overlap 20sm of scaffolds decks from the both sides).
16.0.3 Normally it's placed in one end up against another scaffold - or as last section against a corner scaffold (grouped).
16.0.4 If user set a direction of fitted bay , then system place fitted bay automati- cally (even if angle of the user's direction is a little bit differ from the system's one. That is because system try to find the optimal for fitted bay placement direction and at the same time user is not always can choose the right one and it can happen that it is not possible to place fitted bay) 16.0.5 When facades are grouped and degree between them is not equal to 90 then fitted bay is placed always.
16.0.6 It is possible to have level differences between two scaffolds. The differences between two deck levels can be up to 1 metre, where the scaffold ter- rain is climbing or descending.
16.0.7 The maximum angle for fitted bay placement is 20 degrees.
16.0.8 A fitted bay can never be larger than the length of a deck - minus 2x20 cm
(overlap in both sides).
16.0.9 The smallest size of a fitted bay can be the smallest deck length - minus 2x20 cm.
16.0.10 When brackets and cantilevers are added, the tubes in both sides are added and also fitted bay is added to bracket or cantilever. 16.0.11 If fitted bay is placed then two facades are considered as one facade, so that there is a single content menu for that system now and icon of added to the system parts appear only on one of the facade.
16.0.12 On elevation user can see facade with fitted bay in the middle section (it is added for better stabilisation) and only one chosen facade with fitted bay section connected to the other facade.
16.0.13 If facades have cantilevers or brackets with different width then fitted bay is added with minimum width.
16.0.14 If fitted bay is added then decks of sections between it is placed could not be as access decks. 16.0.15 If decks in section to which fitted bay is connected are removed then fitted bay can not be placed. 16.0.16 To remove fitted bay user should remove one of facades or press Alt and drag one of the facades. 16.0.17 If there is two facades at 0 degree connected by fitted bay and another one at 90 degree is connected to the fitted bay section, then if move this section to the place of other section in 0 degree facade and length of new section (which is placed now instead of old) is not long enough (so that fitted bay cross the post of section) a dialog for user is prompted about loosing of connection. If section length is enough then fitted bay keeps staying. 16.0.18 Inside guard rail is never used on fitted bay, because scaffolder can't work with building in this case.
16.0.19 For extra safety, the guardrail (which does not fit to the size of fitted bay section) must sit on the INSIDE of standard (scaffold guard rail is fastened to).
As a general rule, place the left side of guardrail in cups as illustrated below, and if guardrail is not available in correct length, the other end is placed on the inside of existing guardrail - and fastened with component GRFK. For other systems, which do not have GRFK component, swivel couplers are used to fasten the guardrail. Fig. 98
16.0.20 If rubber tube section, cantilever section or wider section is placed next to fitted bay, then place the guardrail in cups > in the point where the wider section begins, and let it go inside the standard in the other end. Image ex- ample below: (Fitted bay on the left side of wider section) Fig. 99
To avoid the guardrail to go inside the wider section, it is placed from the right to the left.
(Fitted bay on the right side of wider section). If fitted bay on the other side of the wider section, then guardrail must be placed in cups from the left and be erected on the inside of the standard to the right. 16.0.21 If fitted bay is placed at facades which are at 90 degree, then each of 4 points of fitted bay must overlap 20sm of the deck, on which it is placed. 16.0.22 If fitted bay is placed and both of the facades are covered with climate shield /shielding then fitted bay is automatically covered with climate shield too. And there is no icon of climate shield/shielding on fitted bay section and on the other facade, because we consider now two facades like one.
16.0.23 If there is an angle between facades then fitted bay deck can't be the same width as basis section. We are allowed to use all decks except 0.3m. But minimum fitted bay width must be not less then 45cm. If scaffold width is more then 0.7, then it is allowed to use 0.3m deck in combinations with other decks, but not as single fitted bay section. 16.0.24 If facades have 90 degrees angle or in same line and the distance between them is 7.5cm or less, we don't need to place fitted bay.
16.0.25 If there are 2 facades in line with safety gate, then shielding must be automatically in fitted bay section.
16.0.26 Fitted bay deck is placed where we have no other deck types for a system.
16.0.27 When we need to place fitted bay between 2 facades, and we have deck of the same width as facade width (for ex. 64) but this deck is longer then we need, and as other choice we have 2 narrow decks (for ex. 32cm) but the length fit to the measurement, we will always place 2 narrow decks with length that fit. Always use component with suitable length, not width. (26.04.2006)
Figure imgf000064_0001
Figure imgf000065_0001
Add/remove secIf the "Add section" function is used, and sections are present on tion both sides, the system must automatically add fitted bay section.
16.1 Fitted bay/scaffold division.
If user have several grouped scaffolds (for example scaffolds around the building) and there is no enough length of facade to be grouped with the other facade then it is possible to divide this facade in two parts and place fitted bay between them. This is expensive decision and can be used if it is not possible to reach section length 0.7, 1.0m or others, because if it is possible to get this length then it is possible to place simple section instead of fitted bay section. The division of facade must be done if distance for grouping is more then 10 sm.
16.2 Fitted bay between facades in 0 degree. If fitted bay is added to facades in 0 degree in front of each other then fitted bay must be added to keep the width between sections. So if sections length is 3.5m then fitted bay must be in width of 3.5 m.
17. H-diagonals 1. H-diagonals are generally used in sections, if no decks are mounted. But when erecting heavy steel scaffolds, H-diagonals sometimes can be erected under the deck for extra stabilization. 2. It's only possible to erect H-diagonals in scaffold systems, which has H- diagonals as reference. 3. H-diagonals are shown only in plan drawing and can be erected crosswise also
(Like normal diagonals).
4. H-diagonals are mounted under deck in section.
5. H-diagonals can be placed by multiselection of sections also.
6. By default left to right diagonals are added in multiselected sections. 7. H-diagonal is placed in 0 level also.
8. H-diagonals are shown if change level to level zero. It is not necessary to show them elsewhere.
9. H-diagonals add only for post and Allround systems.
10. In 0 level diagonals are added but decks in these levels are unneeded. 11. It is not possible to place h-diagonals if access decks are placed (item h- diagonal is disabled in menu). 12. It is only possible to add one type of diagonals to one section (left to right or right to left, or crosswise). So every time user adds new type of diagonal to the section, the previous type is removed.
17.0 Functionality in plan:
- 'Add left to right' fig. 100
- 'Add right to left' fig. 101
- 'Remove'
Functionality should be possible for a single section, multiselected sections, whole facade or a whole level, from bottom to top. Also in level 0.
NOTE: THIS FUCTIONALITY IS FOR +8, AND ALL OTHER SYSTEMS
TOO. H-diagonals are generally used, when decks are removed. Then we need to stabilize the scaffold. They are also used, if user uses decks without hooks, or decks that do not fit into the system.
(It could be special designed decks, if a certain scaffold construction is made > 3rd part component, which user should add to system himself in Setup) We cannot know, in which situations user chooses to use other decks, and therefore it must be possible to add H-diagonals manually in ConstructIT. For +8 H-diagonals are not used very often, and most commonly for scaffolds on wheels, which we do not have in ConstructIT at present.
17.1 H-Diagonal components
It is only possible to place an H-diagonal in a section, if the H-diagonal component fits exactly! !
Example 1: Fig. 102 Example 2: Fig. 103
If we have a diagonal which fits a square shaped field (125/125), then it is NOT possible to use it in a rectangular field (125/70). This is because there cannot be less than 45 degrees between the locking positions of the diagonals in cups. (Illustrated at fig. 104
3. Complete component list for +8 H-diagonals:
18. Move section
1. If user wants to move a section to a new location in facade, he should press the Shift key and left mouse key on section and drag it to a new location.
2. When dropping the section the guardian rail, cantilever, bracket and deck moves together with it.
19. Multiselect
1. On a facade it is possibly to select more than one section. By multi selecting, the user can add different elements. After adding an element multi select is removed.
2. To make a multi select, the user should press the Ctrl key, together with left mouse click and chooses the sections he needs to be selected.
3. To make a deselect, press Ctrl key together with left mouse click on facade and click on selected sections. 4. By multiselect it is possible to remove selected sections on plan.
5. If some sections are selected, then item Append section is disabled
18 Gr oup/Un group
20.0.1 If grouping two facades without any angle between them, the user must choose which vertical posts shall be assembled. One section has 4 vertical posts.
20.0.2 There can be more than one facade grouped to one section. By ungrouping a facade, all other grouped facades which are connected with that particular one, must be ungrouped but if they are grouped between each other they must stay grouped.
20.0.3 Two grouped facades have one join post in case if the angle between the facades is not less then 45 degrees. If the angle is less then 45 degrees then it is not possible to group facades with one join post, it will be two separate facades but close to each other and connected with couplers.
20.0.4 For grouping user should press Alt and by Left mouse key drag chosen facade to the point of other until the small red square appears (connection point).
20.0.5 The grouping points stay after moving section. And facade also stay grouped, until user decides otherwise.
20.0.6 User can group 3 facades by press Alt and drag facade to the other facade connection point. 20.0.7 If facades are grouped then icon of grouping appears.
20.0.8 If facades are grouped side to side then guard rails at this side must be removed or changed in size (according to the way of grouping). Fig. 105
20.0.9 If some parts are added to the facade (bracket/cantilever etch) then guard rails is also modified according to the scheme. 20.0. lOIcon shows the way scaffolder can go through facades (icon with arrow).
20.0.11It is not possible to group facades so that they can intersect each other or intersect added to them parts.
20.1 Group / Ungroup without grouping point
1. It is possible to make facades grouped if just move them close to each only in 90 degrees. If other degree, then fitted bay is used.
2. To consider facades grouped without grouping point the distance must be from 0 to max 10 cm close to each other.
3. This kind of grouping has the same rules as normal groping regarding to guard rails. 4. To make facades group/ungroup user need to press Alt button and drag facade close to the other facade and there are no red circles that point grouping place in case of grouping point. 5. Grouping symbol appears to show that facades are grouped together.
20.2 Grouping facades /remove section inside 1. If grouping some facades one to other front-to-front, then it is possible to remove section inside of this construction, so that we can have some kind of hole inside square inside grouped facades system. And this is need for special works in England, for building scaffold constructions around the building. 20.3 Group when difference between levels.
If we have level difference of max 0,50 cm, then the workers simply walk a step up/down from one scaffold to another, (so level difference from 0-50 cm, then nothing is added) If level difference of more than 50 cm, then a guardrail is added in the level 'hole' space. For closing. And a deck is placed in angle, to get access from one scaffold to the other. The hooks of the deck is fastened to the upper part of the guardrail.
20.4 Grouping facades for Bosta 70 Fig. 106
Remove base jack in longer facade (so that corner frame has now only 3 base jacks). Use 2 couplers to connect frames together form outside in top of frame (where a small corner can be used) and in bottom (near diagonal fastening point). Remove outside guard rail in shorter facade to let scaffolder goes through scaffold.
Decision about frame saving when group frames in 90 degrees (bracket component placement instead of frame in grouped facade).Fig. 107
20.5 Grouping facades in 90 degrees from inside of building Fig. 108
21. Drag drop
1. With drag of a facade, it must be placed in the angle the user has chosen from the "Facade properties" box.
2. In this list there are Length and Height of facade the user draw, and also the angle of facade can be chosen.
3. If the facade is dragged over the starting section of an existing facade, it will automatically be grouped together in 90 degree angle. 4. When dragging the facade, it should never cross the other facade. By dragging from Advanced facade icon, all section combinations are displayed, and the user can by double click choose from this list to the plan drawing. If there is one (or some facades) already placed on plan, then by dragging the other facade user can intersect existed one. In this case system notify user (TMS message in right bottom corner) about facade intersection. Dragged facade is placed where user put it on plan but in right mouse menu there is only item for this facade 'Remove facade' (so that if the user ignore message with offered action, the only way is to remove facade and drag the other one again). 22. Change section length
1. To change section length there is an item in popup menu with specified section lengths.
2. There is a request for user about changing section length. 3. If some parts are added to the section then system check for automatic resizing and all added parts should stay added to the section.
4. IfUTV is added the system check for size and if the length of deck is not enough then request about removing UTV appears.
23. Append section
1. To append section there is an item in popup menu with appropriate lengths.
2. Section is added from the right side of selected section.
3. If section is added after the first section then other sections in facade are moved to the right so that they are placed after added section. 4. If section is added then terrain line reach new section
5. If gable is added then gable outline should reach new section margin.
6. If user uses Append section, then always simple section is added. And it not depends on what part are added to the section (bracket, cantilever, rubber tube etch.)
24. Remove section
1. To remove section there is an item in popup menu.
2. The request about changing facade height appears
3. If remove section then system recalculate position of other sections. 4. All added parts are removed with section which is removed
5. All added parts to the other sections change their position.
26. Remove facade
1. By removing a facade, the facade must be marked for recovery, by quitting the program all unrecovered facades will be removed.
2. There has to be an option: The user must be able to choose between animated/not animated removal of the facade - and there must be an undo function. 3. When removing the facade, it goes to the recycle bin - it shall be possibly to go 5 steps/deleted facades back for restore.
4. If user removes selected facade then request appears so that user can always agreed or cancel removing.
27 Shielding
27.0.1 By adding the first shielding, a symbol is placed on the plan drawing. 27.0.2 On elevation shielding is shown by dark colour. 27.0.3 The shielding is visible on elevation front and side.
27.0.4 The shielding can be added to the whole facade and to the section separately.
27.0.5 If some sections are added to the top section then shielding must cover all sections which were added and become as top now and sections from the left/right side of these top sections, so that all top was covered.
27.0.6 To remove shielding there is an item in popup menu. 27.0.7 If shielding is placed from the both sides of fitted bay then on fitted bay section shielding is placed automatically.
27.0.8 Shielding can be added to fitted bay as to simple scaffold section. 27.0.9 If cantilever is placed then shielding cover cantilever from end sides and outside. 27.0.10 If bracket is placed in edge sections then shielding covers both bracket and central section
27.0.11 If rubber tube in cantilever section then shielding is placed automatically 27.0.12 If length of section is changed then shielding must stay and be modified with section length.
27.0.13 It is possible to add shielding and electric hoist together 27.0.14 Shielding must be added to all the top sections (sections above which no sections are placed, except electric hoist) and cover the whole levels that include top sections (beginning with the lowest top level if gable (or some sections in top) is added).
29. Description 1. By this item menu it is possible to add description of facade.
2. User insert text in Road description window then can accept or cancel these changes.
3. By default in road description there is a numeric number of dragged facade. 4. If default description is changed then new description appears near the facade so that user can always see name of facade.
5. If description is add to facade and some other parts are added, then it must not be possible to let icons of these added parts overlap description. So description must be moved so that user can read it easily. 6. The default number of facades stays always, and it does not depend on the adding or deleting of description."
30. Measure distance
1. By item in popup menu it is possible to measure some distance on plan draw- ing.
2. There is an initial and end point.
3. In bottom of plan window there are X and Y coordinates. Also there is a modification distance by these coordinates. And also distance between initial and end points. 4. It is possible to measure distance of facades that are placed at different (optional) degree.
31 Change level
31.0.1 This is separate menu. By using this menu it is possible to see what com- ponents are added to the whole facade or to the separate level and also possible to add/remove components from the chosen level. 31.0.2 User can see view from top if slider is set at All levels. If slider set to 'All' then add/remove components work as
31.0.3 If slider is set to the separate (exact) level then it must be only possible to see what components are added to this level (it does not depend on the whole facade construction).
31.0.4 If for ex. Protection fan is added to the level 4m, then if slider is set to this level - we can see protection fan. It is also possible see protection fan if level indicator is set to All. But we can't see protection fan on plan if level indicator is set to for ex. 8m level.
32. Navigator 1. There are different Navigator factors: 1:15 - 1:500.
2. Every time a cursor is moved the plan drawing is updated.
3. Grouped facades stay grouped.
4. Each time the user chooses Navigator window, the drawings stay in centre.
5. Is chosen by mark at Tools options F3. 6. There are Zoom in, zoom out and optimal fit options
7. By dragging indicator user can choose appropriate zooming.
8. It is possible to see Elevation and Side view by right click in window.
9. By Ctrl click it is possible to create navigation are in window.
10. There is a "zoom scale" in top of window and "zoom in/out scale" in bottom of this window.
11. All the changes made with facade are reflected in Navigator.
12. If user rotates facade and some of its parts are not visible on plan, then scroll bars appears so user can use them to se part that are not fit to size of plan drawing. And in Navigator window working area also changes its size and user can move it instead of using scroll bars.
33. Horizontal
1. Horizontal is used in post systems for placing decks.
2. Horizontals are not used for frame systems. 3. They are placed between posts to hold decks.
4. They aren't placed in 0 level, only if some special setting used for scaffold.
5. If ladder is placed in 0 level then also horizontals are placed from the both sides.
6. The horizontal is decide how wide the scaffold can be 7. If we have scaffold of width 0.7 then horizontal length is 0.7m
8. Reading the reference of horizontal to make the scaffold width in menus
9. For crosswise deck placing we calc only horizontals on which deck hooks are placed (see figure 28) 10. If 2 crosswise decks one by one then we need to calculate horizontal between them because of extra stabilization of scaffold (see fig. 29).
11. For lengthwise decks we calculate horizontals from left/right sides of deck (see fig. 30)
12 In 0 level we does not calculate left (for left section)/right (for right section) horizontals. For one lengthwise section wider than the other sections, we keep posts of basic scaffold from end side and from left or right sides too.
12. For ALLROUND system we calculate horizontals from all sides of section (so if we drag out the Allround facade then we have horizontals from inside/outside of the
13. Scaffold and also where hook decks are placed). And we also calculate them in 0 level because this is special scaffolds system. 14. If there is a crosswise section in the middle of scaffold then we need to calculate horizontals from the all 4 sides of section
34. Autocentering
1. If user drags a facade, then it is placed in the centre of the working screen. 2. If there is another facade placed in working area then the system must automatically place it, where space enough.
3. It is not possible to place one facade above the other. System will send a request for user about facades crosses each other.
35. Algorithm of section calculation
1. If user set some length in New facade menu, then choose Advanced facade dialog, there are different sections combination for the length is set.
2. System calculates appropriate number of sections in facade to arrange as small sections as possible. After system check where the smallest fault of length is. 3. Algorithm is calculated below:
Let Factor = measure/100 Then Margin = const ± (Factor*2) where const is equal 15sm or 7% of the length but not large then 30sm. So that if 7% of length is smaller then 15sm we use const = 15, otherwise we use percentage.
36 Net/plastic
Requirements description
• Plastic / Net is used in general for protection against weather conditions, or to prevent material from falling off the scaffold.
• Plastic / Net are 3rd part components, and the scaffolding companies buy it from their manufacturer - it is delivered on large rolls, normally in 3 widths; 2,20m, 3,3m and 4,0m.
• In general, if net/plastic is added, and there various components are added (like cantilever, rubber tube, WTF..), then system should prompt dialog for user, if he wants to cover component/components with plastic/net. • In general, if we add components (like cantilever, rubber tube, WTF..) to facade AFTER adding net/plastic, then dialog should be prompted, if the net/plastic should cover those components. Example of plastic: Fig. 109
Function uses following component references:
• 17 - Net
• 18 - Plastic
• If there is no reference attached to the 3rd part components then Net/Plastic should be disabled User actions:
• No special user action, all functions are controlled from menu system. Restriction regarding actions:
• One facade can only have one of the components present at the same time.
• It is possible to have both shielding and Net/Plastic added to scaffold. • If there is one single facade side, plastic/net must cover the outside and the sides of scaffolds as well. (It covers the sides and is fastened to building with some kind of hooks). In this case width is equal scaffold width + distance to wall + overlap (if it is vertical Net/Plastic) • If we have more then 1 facade sides then plastic/net covers scaffold around the corner, but not at the side of facade, which is grouped. Illustrated at fig. 110:
• When WTF is added, its ends are not covered with net/plastic (but scaffold ends are covered).
• If we have horizontal net/plastic, check when the roll width ends and start placing next net/plastic roll at angle from this point. If roll width is wide enough to cover facade shape as precise as possible, then net/plastic must repeat exactly scaffold shape (without any angles in NetPlastic placement)
(see schematic image at fig. I l l)
• If roll width ends somewhere near tubes of WTF component and next roll is for ex. 4m in width, we calculate 4 m roll in bottom, but draw it only un- til height, that is set as parameter in Setup.
• At least one anchor in each joint of scaffold is placed in all levels (for all systems).
• If in Setup parameter 'Top level covering' is set to 2m then sections of 2m height must be built. In top of them (for post systems) horizontals must be mounted (if system cannot find horizontals that tubes with 2 couplers must be used), so that it possible to fasten net/plastic to them. Horizontals are also mounted in end sides of scaffold. For frame system we use tubes, 2 couplers for each tube.
• In this version we do not have functionality that we can add to a single section or column, we can only add to the whole facade. Use multi select functionality for free choice of sections/columns to be covered with Net/Plastic.
• Shielding can be used with net/ plastic.
• If Climate shield is added to the top of scaffold, Net must be added starting from the level under Climate shield.
• When Plastic is mounted under Climate shield, then summarize all used plastic, which covers the climate shield components and the rest of facade, and the total amount of plastic is shown in calculation. (02.08 Lene) • Don't restore automatically net/plastic up to parameter 'Top covering' if Climate shield was added and then removed.
• If protection fan is added to the facade then net/plastic must be placed down till protection fan deck also cover the section below PF • When cover scaffold with net/plastic there is no difference between simple facade and facade with gable
• If gate is added to facade then net/ plastic cover left and right sides of scaffold in gate area (left/right gate sides).
• If rubber tube is placed then net/plastic covers the whole facade together with/without rubber tube (according to user's answer on request).
• If UTV is placed then net/plastic covers the whole facade including the UTV section.
• If Cantilever is placed then net/plastic covers the whole facade including the cantilever section/sections. • If Cantilever is placed then system mount 2 posts/tubes to bracket posts with couplers, so that section is 2m in height and cover it with net/plastic.
• If ladder is placed from the outside in bottom level remove the plastic in this section, so there will be a door hole between AVS and post/frame.
• If there is EH is placed on facade then don't cover EH section and section under EH (doesn't matter if EH use section or not)
Parameter in setup:
• Overlaps of plastic/net widths per default 10 cm. ( List measure intervals with 5 cm between - starting from 0 cm - 50 cm.) • Amount of straps per m2 Per default 1 per m2 (List choices - from 1-5 straps per m2)
• Mounting of Net (direction) Per default Vertical (List choices 'Horizontal' and 'Vertical')
• Preferred Net width Should be chosen from the 3rd part com- ponent list via the reference.
• Mounting of Plastic Per default Vertical (List choices 'Horizontal' and 'Vertical') • Preferred Plastic width Should be chosen from the 3rd part component list via the reference.
Top level covering (O, Im 2m) If user chooses Im then plastic/net starts in top from Im above top deck level.
Cut pieces Checkbox, where user define is it acceptable to cut pieces from the roll or not (for running meter calculation). Menu layout in Designer / Plan: • Facade / Net - add remove properties
• Facade / Plastic - add remove properties
• If choose properties menu following parameters are present:
- 'Width' (list choices read from setup references)
- 'Mount vertically'
- 'Mount horizontally' - 'Include top level'
- 'Distance from bottom edge to ground' by default is 50sm (the same with WTF)
- 'Reuse' (This is for DK only) Menu layout in Designer / 3D: • When we add plastic, it should visually cover the scaffold outside all the way to the ground.
• Show overlapping of plastic widths like illustrated below. Then it is clear if plastic is mounted vertically or horizontally.
• Don't show straps Plastic mounted vertically Plastic mounted horizontally fig. 112
Example of Net fig. 113 Calculation issues:
• Straps are calculated based on the parameter Number per m2 multiplied by net/plastic m2.
• At least one anchor in each joint of scaffold is placed in all levels (for all systems).
• If roll width ends somewhere near tubes of WTF and the next roll if for ex. 4m we calculate one more time 4 m in bottom, but draw it only to bottom until height, that is shown as parameter
• Algorithm of plastic running metres calculation. Lets scaffold is 10 m in height, 10m in length, 0.7 in width, distance between scaffold and wall is 30cm, plastic overlapping with wall is 10 cm, roll width is 4.40m.
First the length which needs to be covered must be calculated.
L = 2 distances between wall and scaffold + 2 scaffold widths + scaffold length.
So L = 12m Plastic must overlap wall from each side at 10cm, when join 2 plastic rolls there is overlapping between them is 10 cm too. Plastic will curve around the posts/frames.
The diameter of cup is 10cm, so we need to cover quarter of 2π(172), so we get 8cm.
We can round this up to 10cm.
Including the overlapping of each roll with the next one, for middle rolls we are al- lowed to use 4.30m of plastic. And for first or last roll additional overlapping in
10cm with the wall must be counted.
So if use rolls one by one the first roll cover 3.20m of the length, next will cover
7.50, next - 11.80. So we have 0.4m to cover with plastic.
If we are not allowed to cut pieces from the roll then we need to use one whole roll. The 4th roll will cover the length 16m.
The length we need to cover is 0.2 + 0.2 = 0.4m * 10m in height is 4m.
So we need 3 rolls + 4m = 3 * 10m in height + 4m= 34m instead of 40m as if we use
4 rolls.
If user is allowed to use different roll lengths then system must start from the widest roll, the last length must be covered with other roll's widths. • In Calculation Part list show how many running meters of the plastic of each roll we need. Fig. 114
37. Shut down If Construct IT is running and user shut down system, then a dialog must be prompted for user about saving. And if nothing is done by user, then a project is automatically saved as draft and after that Construct IT is closed.
1. Initial right mouse click context menu consists of fa- cade, section, measure distance and description items.
2. Facade menu consists of:

39. Properties in right mouse menu
1. If user wants to change properties of facade, then there is an option in right mouse menu. If choose this option then a window with properties fields appears. Fig. 117
There is a possibility for user to change height, width and length of facade. It is possible to choose different types of scaffold. And also if user make some changes and save them as tasks, then he can choose some task and apply it to current facade. If some fields in bottom are marked, then these parts will be automatically added to the facade after edition. This menu option is relative to the F4 properties menu.
40. Add/Exclude components It is possible for user to choose (use or exclude) some components for facades creating, that are not used in real life or are not used by different scaffold companies. So that user can choose if he able/want to build scaffold with default deck length (for example), or he may set some another length that is not provided by scaffold compa- nies. In that case if such dimensions of components are not legal for using them, facades will be built from components that are marked with red colour.
41. Tank section calculation 1. Type in the wanted width of scaffold
2. Type in the tank radius
3. Type in the smallest distance from Scaffold deck to tank (minimum 5 cm )
4. Type in the length of the fixed section
5. Check the distance 'Y' - if more than 0,30 m, then choose a less length of the fixed section
6. Read 'M' - amount of fixed sections - choose the nearest integer, which is smaller, and write it in MChoice
7. Read LB. This number is the average length of the fitted bays. Type in respectively the nearest larger and smaller standard measurement 8. Read det necessary amount of fitted bays of each size. This number is found, when the sum of fitted bay just goes from being 'too short' to 'too long

See fig. 31
39 Scaffold width fig. 118
But for example if user has scaffold width 1.75m and place bracket lOsm for +8 system (post), then in this case it must be placed 3 decks in 0.60m because the total scaffold width is 1.85m now and hooks on deck are placed including the variant when main post must be between two deck hooks.
Calculation of fitted bay length The calculation is based on the average fitted bay length. At calculation 2 end guardrail sizes are chosen, one at each side of the average fitted bay length. Where the total distance is closest (just above I), this is the optimal mixture of fitted bay. See fig. 32- 35
REOUIRENMENTS FOR STATICS CONSTRUCTION CALCULATION
General
Considerations about Security Systems in connection with statics calculation
1. PARTIAL COEFFICIENT- method
This methold is used in all engineering related calculations
The effect on the construction from load x factor (partial coefficient > 1) is estimated in proportion to carrying capacity / factor (partial coefficient > 1)
i.e. that the load is multiplied and valued against the strength divided with the partial coefficient.
Hereby a guarantee is obtained, that the constructions can be proof against the influences from the loads.
SECURITY can be expressed as the difference between the effect from the loads and the ability of the construktion to handle it.
Example:
If SECURITY = 2, then the construction can handle double load.
NOTE! The SECURITY is the guarantee, that eventual inaccuracies and insecurities not taken into account, can cause break down. So - security MUST be present. Never use up the securities. As all scaffolding manufacturers, so to speak, give the values for what a scaffold or its single parts can stand up to as ALLOWABLE values, then in the following the TOTAL SECURITY-method is applied.
2. TOTAL SECURITY-method
This method places the whole security on the given ALLOWABLE values and then uses the actual values for the load measure.
This corresponds to what to be said in real life: Example: The scaffold must be able to carry 2 ton. This means, that the load actually is 2 ton.
UNITS
Normally we state weight measures in kg or ton, but gradually it has become more common to state weight in kN (kilo newton).
Approximately the rule is: 1 kN is equivalent to 100 kg or 10 kN is equivalent to
1 ton.
LOADS
The influences from the loads can behave as follows:
• Single forces - kN Concentrated influence on one point
• Lined load - kN/mLoad applied along a line is stated per length unit.
• Surface load kN/m 2 The load applied to a surface is stated by area unit.
LOAD TYPES Natural forces - Wind is the only present, because snow load always will be less than the present class load of scaffold in question. That is, because in this case roof covering is not taken into consideration.
Wind can behave both as pressure forces and soak up forces, and works in all directions in compass angle.
NOTE: More detailed description in the WIND LOAD part.
Tare - The weight of single components included in scaffold construction. The load takes effect in the centre of gravity of the component.
Surface load or payload - The loads in the form of people or materials stored on scaffold. The surface load is defined according to the described classes in HD 1000.
The Single forces shown in the table are mainly used to dimension the single components during the statement. Therefore it's only the surface loads, which has relevance here when calculating base jack pressure.
Class 1 0,75 kN/m 2
Class 2 1,50 kN/m "
Class 3 2,00 kN/m 2
Class 4 3,00 kN/m 2
Class 5 4,50 kN/m 2
Class 6 6,00 kN/m 2
According to HD 1000, you must take into accont, that one deck level can have a load of 100 % of the class load - and that another deck at the same time can have a load of 50% of the class load. Load from equipment erected on scaffold - is specified as the weight of the equipment in kN, placed in the centre of gravity of the load.

WIND LOAD
STATIC LOAD - for anchors fig. 123
Figure imgf000094_0001
Figure imgf000095_0001
The following indicated values for the wind load relate to the standard of the Danish engineering association for load on constructions DS 410 (4.1), and are therefore applied to danish conditions.
Kvasistatisk charactaristic wind load F w = q max x c x A
DS 410 states 4 different terrain categories
- Plain terrain / sea areas Agricultural areas Suburbs- or industrial areas Urban area
Dependent on, where the scaffold is placed in the country.
The wind load will vary for the 4 categories, with the smallest in urban areas.
In accordance to DS 410, the wind load calculation is based on a set of formulas, which take many factors into account, and mathematically are quite complicated. The advantages by an accurate determination of the wind load calculated by these formulas are limited. Therefore a simplyfied method is used, on which a great deal of attention are paid to the factors in question.
The conditions for simplyfied calculation:
A basic wind speed is used = 27 m/s (corresponding to the highest of the ones prescribed)
The season factor is set = 1,0
The direction factor is set = 1,0 The reference height is set = 30 meter, which corresponds to the normal maximum height, for which the scaffold systems are approved for. Reduction factor for non permanent construction = 0,84 (less than 1 year of use) The topography factor is set = 1,0
The peak factor, the term for the influence of the wind turbulence is set = 3,5 The wind pressure are calculated for the 4 terrain categories in the height = 30 m The form factors, according to the shown figures.
Covering of scaffolds. (Reference to scaffolding standard documentation)
Degrees of tightness for covering D
Bare scaffold 20%
Net 50%
Plastic or tarpaulin 100 %
I.e. the percent indicates the volume of the scaffold against wind. Charactaristic maximum speed pressure for the 4 terrain categories become:
Category
I l,l kN/m 2
II l,0 kN/m 2
III 0,8 kN/m 2
IV 0,7 kN/m 2
Form factors C
Fig. 124 If L = 20m, H= 15m then e = 30m
As it appears, the form factor varies, dependent on the location of the building, on which the wind pressure is calculated.
General considerations:
Facade pressure c = 0,7 Suck on facade c = 0,3
Suck on gable or facade, if the wind blows into gable c = 0,9 which causes that the scaffold is affected by suck on c = 0,9 in fields calculated from corners over the length e metres - where e is defined as the smallest of the sizes, width of building b and 2 x height of the building.
The calculation method is as follows:
1. Choose terrain category I - IV and then q max as stated 2. Choose covering and hereby tightness factor
3. Choose placement on building and hereby form factor c
4. Calculate the wind force of the formular
q max - maximum strainforce on link In calculation we use 1A of distance between two anchor points. And does not meter how long distance between anchors is. F w = q max x c x D x A, where A is the area, the anchoring covers.
The area per ancoring is determined from the rules of the manufacturer for covering pattern (rules)
Example: Prescribed anchoring for 3 metre fields - per every 4 metres in the height.
A = 4 x 3 = 12 m
NOTE! Notice, that it's customary rule to anchor in all nodes, if the scaffold is covered with plastic (Reference to scaffold standard documentation)
Likewise it is prescribed by the majority to anchor along the scaffold edge.

BRIDGING BEAM FIXATION
STATIC LOAD - for bridging beam fig. 126
Figure imgf000098_0001
Calculation method
Step 1
Calculate the pressure on deck, or rather on the standard placed upon the ALU bridging beam. ( See earlier method)
Step 2
Examine, if R deck < allowable single force placed in center of ALU bridging beam according to information from the manufacturer.
IF YES - the construction can absorb the loads
IF NO - add suspension with TUBE + COUPLERS (see image above) Step 3
Calculate the force, which has to be absorbed by TUBES + COUPLERS D P
D P = R deck - P allowable ALU bridging beam
Step 4
Calculate the forces in the TUBES according to the formular (parametres - see image)
P tube + coupier = ( V4 x D P ) / cos D = ( V4 x D P x Λ/ ( H 2 + L 2 ) / H
Step 5
Examine P allowable coupler / P tube > 1
IF YES - the construction can absorb the loads
IF NO - then following amount of further suspensions or skidcoplers must be added
N = (P tube / P allowable coupler ) - 1 NOTE! Nearest integer, which is larger
At the red marked up area at the end of the bridging beam (red circle on picture in top) is calculated: 1A X the tare of ALU bridging beam.
The diagonal with couplers will drag the reaction from the bridging beam up against the post which afterwards will influence on the base jack.

Calculation tab has main windows:
1. Select facade
In this window all of the facades which are used on plan are in list. By mark every facade (or choose some of them / all of them) user can calculate naumber of parameters and calculate teh price of them.
2. Print Plan
By press this button user can see print preview and then print plan drawing with indication of scaffold type. All of facades on plan drawing are visible in this window. In this report user can see in left top of screen there is a name of module (for example 'Plan drawing'). Then in left bottom side there is an information about scaffold (scaffold type, measurements, customer name, address of project). In the right bottom side there is an information about scaffold (type and measurement). In the centre of the screen there is a picture of plan drawing with scaffolds and nothern side arrow. By default picture is fit to screen of report, so that user can see exactly facades. And also report should be as landscape. Margins must be as in word document, so that plan drawing image is fit to size of space without text information about a porject.
3. Print Elevation
By press this button user can get print preview and then print Elevation and elevation side and plan view with indication of facade type. It possible to see only selected facade. This report looks just the same as report for plan (general information, drawing placement etch.)
4. Print Erection Just the same as plan printing but also there is a list of extra parts which were added to facade. Example of report looks like fig. 138 Project name +8 Erection guideline:
Al Access platform with ladder 0,60
A2 Access platform with ladder 0,60
A3 Access platform with ladder 0,60
B4 Shielding
C4 Cantilever bracket 1.00 m
5. Edit Erection In this window user can edit Erection information
6. CaIc separately / All facades
If this field is not marked then all parts of facades that are placed on plan will be caunted in report together. If 'CaIc separately is enabled, then in part list area, we need to Instead of enabling each facade in left upper corner, each time we want to calculate a facade - then we have to add main tabs in bottom: 'Facade 1 ' , 'Facade 2' etc. So taht system will consider them in report as one join facade. If this field is marked then user can see result of calculation of parts separately for every facade. If we have more facades, then on 'Calculation' tab, we need by default to calculate all facades at once, if 'CaIc separately' is disabled. All components from reference added to facades must appear in part list. In left column (where we now have partlist for ex. 'Facade 1 '), this text must be replaced with 'All Facades')
7. CaIc price Price type

8. Calculation
In the bottom o fwindow the buton with calculation of static load should be added. The result of static load calculation should be outputed as Excel table (for baseajcks, for anchors and bridging beam) as diagramme with drowig. If there is much heavy scaffold then for it is not needed to output data as table but system show an overload of part. And elso in result it is necessary to see exact product name. In this window user can see part list report. It is possible to modify report view by using menu items in editor. By clicking each facade tab (for every facade there is a separate tab), then the sub tabs appears; 'Part list', 'Base jacks', 'Anchor points', 'Beams' where static loads is calculated for different parts.
By press this button user can print part list of selected facade/facades. All parts that are used in this facade are shoun in this report. Main fields of report are: Facade num- ber, Part name, ArtNo, Quantity, Length, Width, Height, Weight. It is necessary fo user to edit view of rport. That means user is able to remove fields he doesn't want to see or change the order of fields to see inforamrion in appropriate consecution.For this it is necessary to make a Sort list dialog so that user can form a quantity of fields and its consectuion. In print part list editor there is an opportunity for user to use hot keys for text formatting such as "Ctrl+B", "Ctrl+I", "Ctrl+U".
8. 1 CALCULATION PROGRESS
When system is in calculation mode, then a dialog with progress bar must appear. (Like OUTLINE progress dialog). Partlist has to appear, first when calculation proc- ess has finished.
9. Erection guidline
1. Erection guideline is a guideline for user, to see which components must be added to the scaffold 2. Description of where in scaffold they are placed is added in bottom.
3. The plan of sections below front view must be named A, B, C. etc. and the sections on front view named 1,2,3... etc. This is for easy visualizing for the user, where in sections parts have been added.
4. Show the project name on erection guideline. 5. Show only front view of scaffold on Erection Guideline.
6. Show front view of scaffold with transparent background (for printout if user wants that), and the drawing must keep the proportions when the guideline is opened. 7. Update erection guideline with the correct components, if user chooses to change his scaffold construction.
All components shall be listed in print part list in erection except the following: 1. Posts / Frames 2. Deck
3. Toe board
4. Guardrail
5. End guardrails
6. Base jacks 7. Horisontals
If one of those components listed above is replace with other component for example guardrail in UTV section we need to tell the user what component the system chosen automatically instead.
10. Function SetComponent
Function is used for settign component for function CountElements.
1. Function must work for all of the elements in system
2. As a parameter function must use Reference-Id
11. Horisontal
1. Horisontal is a part on which decks are palced.
2. They are used only for post systems.
3. They are placed between posts to hold decks.
4. They don't placed in 0 level, only if some spesial setting used for scaffold. 5. If ladder is placed in 0 level then also horizontals are placed from the both sides.
6. The horizontal is decide how wide the scaffold can be
7. If we have scaffold of width 0.7 then horizontal length is 0.7m
8. Reading the reference of horizontal to make the scaffold width in menus
9. For crosswise deck placing we calc only horizontals on which deck hooks are placed (see fig. 139)
10. If 2 crosswise decks one by one then we need to calculate horizontal between them because of extra stabilization of scaffold (see fig. 140). 11. For lengthwise decks we calculate horizontals from left/right sides of deck (see fig. 141)
12. In 0 level we does not calculate left (for left section)/right (for rigth section) horizontals.
13. For ALLROUND system we calculate horizontals from all sides of section (so if we drag out the Allround facade then we have horizontals from inside/outside of the scaffold and also where hook decks are placed). And we also calculate them in 0 level because this is special scaffols system.
14. If there is a crosswise section in the middle of scaffold then we need to calculate horizontals from the all 4 sides of section
12. Anchors length calculation algorythm General algorithm for definition of anchor length.
1. It is calculated like this:
Anchor length = Distance between scaffold and building + bracket width (if brackets) + 10 cm (10 cm because then the anchor can be fastened to the inside post, closest to the building. This is for all systems post/frames.
Distance between building and scaffold is set by default 0.3m (but it also can be changed if user change distance between building and wall by himself)
2. Do not define scaffold width, we don't need it in calculation. 3. Choose the anchor length according to the rules above: Anchor length = Distance between scaffold and building + bracket width (if brackets) + 10 cm (10 cm because then the anchor can be fastened to the inside post, closest to the building. Make sure the anchor can reach the building to be fastened, and it is allowable, if the anchor is too long. So that, if we have 1, 2 and 3m length anchors in list and we need 1.5m an- chor then we choose 2m length from list (and it doesn't depend that it is longer then we need) 4. For now we build facade and this facade doesn't know anything about building. So if add bracket to the scaffold to middle section, then the length of anchors in all sections increases, according to the distance increasing. That's because if we add bracket to the scaffold then bracket does not go inside of wall. That is why we need to sum distance between scaffold and also bracket length to calculate anchors length.
13. AVS for walk through frame
1. AVS is a component sitting on the walk throung frame
2. Component is calculated for each section where it is present (for picture below there is 4 sections facade and there are 5 AVS for walk through frame)
3. If walk through frame is present then extra standards are placed (walk through frame bottom frame used with S2 as support)
14. Climate shield (Functionality for +8) 1. STANDARD 0.5m BENT (300168)
We need to calculate number of meters extra posts, and how many Standard 0.5m bents, and then put in 1 m post and connect guardrail between the two posts, see fig. 37-39.
2. Guardrails are placed in top for stabilization of the climate shield construction.
3. Place the guardrails in the 1st cup of Standard component (S) in all sections in whole scaffold length.
4. Rule for inside post: (purple indication on image)
If Standard component in top is more than 1 m, then place the inside post for stabiliza- tion. If less then do NOT place it.
15. Couples (for bridging beam)
1. If gate is added, then bridging beams are fastened with couplers to the posts (at each side of scaffold). So this is 4 couplers per bridging beam. 2. Use swivel couplers for frame.
3. We don't use couplers for post systems 4. When wide gate is built on facade then more bridging beams are present above the gate, then bridging beams are fastened together, and I do not know where exactly (TL will be torbiten) se fig 40.
16. Bridging beam
1. Bridging beam is placed form the both sides of the scaffold.
2. If gates are added then bridging beam is placed of length which is closes or more then gate width.
3. For wide gates there are several bridging beams placed and they are fastened with couplers. Now we have only one Reference called Bridging beam and on this reference there are 2 components: Still bridging beam and Aluminium bridging beam. So if it is necessary to check which component is used in reference, check the method Material .
17. Missing component part list.
This is a kind of report where user can see components that system is not able to place (and also calculate) by itself and user has the opportunity to choose what component must be placed. For example, if user adds access decks in all levels but bottom level is 1.5m in height and system has only ladders for 2m sections, then on Calculation tab at Missed component list from Art.N° we have a combobox. User chooses from this combo any component he wants to use instead of ladder that system is not able to place. So this component will be calculated, but it is not shown in system. On this tab while component from list is not chosen it is marked as red crossed circle. If user choose component from a list then it is marked as green color V.

Make Orthophoto
For the computation of distances it is important that the plane which is to be rectified is as parallel to the film plane as possible. In other words: the camera axis should be as perpendicular to the rectification plane as possible. This means the camera station has to be exactly in front of the plane, whenever possible. However it's rarely possible in real life and photo has distortions.
Orthophoto function allows correct sides of photo.
User clicks Orthophoto action to start sub-flow.
Orthophoto window
The systems show Orthophoto window.
