Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be executed by using an arithmetic processing unit such as a so-called personal computer, and is a stage before designing when designing an object to be designed in the field of architecture and civil engineering. By inputting the basic data that can be known in, the designer executes the embedded processing procedure suitable for obtaining the cost required to construct the design target for the construction of columns, beams, and floors. The present invention relates to a construction cost calculation support method for a new construction / civil engineering design capable of calculating in advance a construction cost which is a reference for designing a design object easily and in a short time.

[0002]

2. Description of the Related Art In designing in the fields of construction and civil engineering, in addition to examination of structural strength, construction cost is also taken into consideration.
We are making design drawings. That is, even if the design specifications are appropriate in terms of structural strength, it is difficult to adopt such a design if the construction costs do not match.

[0003] Conventionally, the construction cost is evaluated by an integrating operation based on completed design drawings. For this totaling work, a totaling program has already been developed, and this totaling program collects these data one by one while picking up the columns, beams, other materials, etc. that are written in the design drawings one by one. By inputting, the integration process is executed.

[0004]

By the way, the conventional way of thinking of the cost and the cost calculation program created based on the concept of the cost calculation are based on the assumption that a completed drawing exists, and input all data to calculate the construction cost. It is a thing. In other words, the construction cost cannot be known until the design drawing is completed. For this reason, if the drawings have been created but the results of integration based on them are not cost-effective, it is necessary to review the overall design itself, including the viewpoint of structural strength, and recreate the design drawings. However, the design work from the creation of such drawings to the total cost was repeatedly performed until the cost was satisfied. Further, such redesigning may impair the productivity in the design work, and eventually the design drawings may not be completed in time.

Further, as described above, in the past, the construction cost is information obtained as a result of the design, and it cannot be evaluated until the detailed design drawing is completed. Therefore, detailed design data is required even if there is a case where it is desired to estimate the construction cost based on a small amount of data that can be known at that stage in the planning stage before starting full-scale design, and to evaluate it. However, the conventional way of thinking of the total and the conventional total calculation program could not meet such a demand at all.

Further, as described above, completed design drawings are indispensable in the conventional multiplication work, and for example, in order to meet the demand for selecting one from a plurality of candidate plans, preparing a plurality of completed drawings. However, it is virtually impossible to create and integrate a plurality of candidate drawings in this way for a single design object to compare and evaluate the construction cost.

The present invention was devised in view of the above-mentioned problems, and its purpose is so-called personal computer.
Execution processing is possible using an arithmetic processing unit such as a computer, and when designing a design target in the field of architecture and civil engineering, the designer must input basic data that can be known in the pre-design stage. In order to design a design object easily and in a short time by executing a reasonable processing procedure suitable for obtaining the cost required to construct the design object for the construction of columns, beams, and floors. It is to provide a construction cost calculation support method in a new construction / civil engineering design capable of calculating the construction cost in advance.

Further, "electric power" is shown in unit price data by dividing it into a basic charge and a usage charge.

On the other hand, the above-mentioned "floor assembly type file" and "partition type file" will be described with reference to FIGS.

In the upper left column of FIG. 11, "floor assembly type" is shown in a tabular form. Here, as a typical example of the floor assembly type, for the three types of "composite slab", "flat slab" and "mountain deck", the erection direction of the girder with respect to the erection direction of the girder is the long side direction and the short side direction. As the formats that can be selected, six types from A to F are listed. And for such 6 types of basic floor assembling, in the lower column shown in the table format, "Number of beam beams" and "Stiffening", and when stiffening is used The floor assembly type file is configured so that any of "beam type", "buckling type" and "brace type" can be selected.

The construction data relating to such floor assembly is stored in the "floor assembly type file" of the storage means 2. The designer can input the construction data all at once by selecting and inputting the contents of the "floor assembly type file" that the calculation unit 4 has read from the search file of the storage unit 2 and displayed on the display unit 3. Yes, to explain one example, as can be understood from the model displayed in the center of FIG. 11, the one selected by erection of two beam 24 in the short side direction is “Study No. 1” and “Study No.” 2), and one selected by erection of one beam 24 in the long side direction and one sub-beam 26 as stiffening is selected as "Study No. 3" and "Study No." .4 ”, respectively.

Further, in the upper left column of FIG. 16, the joint types are shown in a tabular form. Here, as a representative example of the joint type, "column through" or "column through" for any column of "square steel pipe" and "assembly BOX" is "column through". In this case, regarding the five types of manufacturing methods classified as “factory processing” or “off-the-shelf”, as a format that can be selected with or without “bracket”, 10 to 10
The types are listed.

The construction data relating to such a joint is also stored in the "joint type file" of the storage means 2. Then, similarly to the “floor assembly type file”, the designer selects and inputs the content of the “partition type file” read out from the search file of the storage means 2 by the calculation means 4 and displayed on the display means 3. By doing so, the construction data can be input all at once.

To explain one example thereof, as understood from the model shown in the lower part of FIG. 16, it is a rectangular steel pipe of the type in which the beam 20 is passed through the column 10 and the bracket 22 is provided. Is selected in “Study # 1”, and it is a square steel pipe that is an off-the-shelf product (the column has no cut surface)
The type that 0 penetrates and does not have a bracket is selected in "Examination # 2", and the assembly box that is the type that pillar 10 penetrates and that does not have a bracket is "Examination # 3". In addition, the square steel pipe that is factory-processed (the column has a cut surface), the type that the column 10 penetrates, and the type that does not include the bracket is selected in “Study # 4”.

The above-mentioned material data, construction data, and unit price data thereof are used for calculation for cost calculation described later.

Further, in the present embodiment, "initial value data" is stored in the storage means 2 in advance in order to simplify the input processing. As the “initial value data”, as shown in FIG. 39, “initial value for corner welding”, “initial value for bracket”, “initial value for diaphragm”, “initial value for girder stud”, “initial value for loss rate”. , “Large beam number related initial value”, “High-strength bolt related initial value”, “BH flange material initial value”, “Construction step initial value”, “Welding step initial value”,
"The initial value of the cross beam step, the initial value of the stiffening step", and the "initial value of the erection related steel frame weight" are preset.

More specifically, "part", "item", and
As shown in the "Initial value setting table" divided into "condition", "remarks", and "selection" items, the "box welding related initial value" is a BOX column manufactured by welding plate materials. For the corner welds other than the joint, the full weld (Full Penetrati)
on) and partial welding (Partial Penetration), and the position condition at the time of switching, what is the distance from the panel zone (portion), on the other hand It is possible to set in advance whether the previous shape is a full welding type or a partial welding type. As a result, the BOX pillar-related cost calculation values differ.

As the "bracket initial value", it is possible to preset the length of the bracket of the joint portion to which the girder is joined (extension of the joint). This will result in weight changes and different cost estimates associated with girders.

The "diaphragm-related initial value" includes a setting when the configuration of the connecting portion in which the diaphragm is installed is a beam threading (through diaphragm) and a setting when a column threading (inner diaphragm). In this case, considering the construction error, it is possible to preset a grade for increasing the size of the diaphragm thickness with respect to the maximum flange thickness of the girder. As a result, the calculated cost values around the joint portion are different.

As the "large beam stud-related initial value", its diameter, its length and its pitch can be preset, and the studs are arranged in a row (single).
The width (column branch width) of the girder to be switched can be set in advance so that the column branch of whether to switch to two columns (double) can be automatically switched according to the width of the girder. . As a result, the weight and the number of studs are changed, and the cost calculation value is different.

As the "initial value of loss ratio", the loss ratio can be set in advance, considering that 100% of steel plate and other materials and shaped steel and other materials cannot be used. The amount of steel, etc. will change and the cost estimate will differ.

As the "large beam number relation initial value", the number of large beams in the long side direction and the short side direction can be set in advance. For example, if both are two, if four girders are joined to one pillar, the center of the building will be the cost calculation target, and if both are one, the corner pillar will be the cost calculation target. If there is one and the other is two, the side pillar is the cost calculation target.

As the "high-strength bolt-related initial value", the heliaki and the pitch thereof can be set in advance, which changes the number of high-strength bolts used and the like, resulting in different cost calculation values. Become.

As the "initial value of BH flange material", it is possible to preset whether or not the flange of BH manufactured by the electric furnace material is limited to wide flat steel. Will be different.

By setting in advance the number of pieces such as columns, girders, and girders that are considered to be constructable in one day as the "building step initial value", they can be used to calculate the number of construction work days. However, this will increase or decrease the cost calculation value related to the number of lease days of temporary materials.

As the "welding step initial value", a day-to-day welding equivalent length is set in advance so that it can be used for calculating the number of working days in the same manner as the "building step initial value". By doing so, the cost calculation value related to the number of days of use of electric power is increased or decreased.

The "initial value of crossbeams" is such that the number of crossbeams to be displayed as an initial value can be set in advance when the data is read from the floor assembly type file and displayed on the display means 3.

The "stiffening step initial value" is such that the number of stiffening lines to be displayed as an initial value can be set in advance when the data is read from the floor assembly type file and displayed on the display means 3.

The "building-related steel frame initial value" can be set when calculating the floor assembly cost by setting the ratio of the column weight to the total steel frame weight. Also makes it possible to calculate the cost considering the steel frame construction.

These "initial value data" can be reflected in the process by opening the search file and changing them by the data input means 1 at any point during the execution of the method.

When changing the "initial value data", specifically, by dragging the arrow portion of the window 7b of the "selection" item at the bottom of each column of the "initial value setting table" with the mouse 1, The stored switchable data is displayed in a list, and it is only necessary to select from these or input new data arbitrarily from the keyboard 1 or the like, and then click the “setting end” button 6.

In the method of the present invention, material data stored in advance in the storage means 2 as a search file and necessary for designing a design target object in the field of construction / civil engineering constructed with columns, beams and floors as described above. While using the construction data and these unit price data, the processing is executed in the following procedure using the above apparatus.

By the way, the above data are merely examples, and needless to say, many necessary data are stored in the search file.

In the following description, the “selectable form” is stored in the search file of the storage means 2 in advance in the form of material data, construction data, and unit price data, and the window 7
When the arrow portions a and 7b are dragged with the mouse 1, a list of pre-stored switchable data is displayed, which means that the data can be selected from these.

6 to 9 show the procedure of processing, and FIGS. 10 to 18 show an example of the display form displayed on the display 3 as the display means at the time of execution.

First, as shown in FIGS. 6 and 10, the data input means 1 first executes a basic data input process S10 for inputting at least girder data including the girder size.

When the basic data input process S10 is executed, the display 3 displays a column of "building outline" and a column of "cross section of girder". In addition, a “print” button 40 for printing the data displayed on the display 3 with a printer, and other “data registration”, “central section 1 size DN”, and various “size search” buttons 42 described later. , 44, 46 are displayed.

The "building outline" is a field for arbitrarily inputting the basic design data that can be known before entering the full-scale design stage for the design object according to the specifications of the design object. Shows the items of “long side” direction span and “short side” direction span as the “study span”, which is the length size of the girder data, and the “study related to the length size of the pillar data. “Floor height”, each item of “1st floor floor number” which is the number of building floors covered by pillar 1 section, and also “Steel floor number” corresponding to the height of the design object, “Steel frame total floor area” of the design object Each item is displayed, and data can be freely input to these items using the keyboard 1. In the illustrated example, the “long side” is 8,500 (m
m), “short side” 6,000 (mm), “examination floor height” 3,
900 (mm), "1st floor number" 3, "Steel frame number" 9,
"Total steel floor area" 6,808 (m ² ) is entered.

In the column of "cross section of girder", size data regarding the cross section size of the H-beam for girder and the manufacturing method and type of the material are input. In this column, there is an item of “small beam direction”, and data is provided for each of two types, that is, whether the beam to be attached to the floor is installed in the “short side” direction or the “long side” direction of the large beam. In addition to being able to input, there is an item of "Large girder direction" so that size data etc. of "long side" direction and "short side" direction of girder can be input individually for each erection direction of beam. Has become
In addition, there is an item of "Part", and the cross-sectional size of the span end and the cross-sectional size of the span center of the girder can be changed as necessary, and a total of 8 types can be input. You can enter the crossbeam data of.

[0107] Further, there are items "manufacturing method" and "H shape" as items for selecting the manufacturing method and type of the material for H-beam for girder, and these are the "JIS" size and the "external H" size mentioned above. Material data and construction data of "steel plate" size and "BH flange material" size related to BH are used. "Production method" and "H
There is a selectable form for the "Shape" item,
Dragging the arrow part of the window 7a at the top with the mouse 1 displays a list of pre-stored switchable data. If you select using this, you can select the desired data for all eight types at once. While the windows 7b ... Can be input, data can be individually selected and input. In the example shown in the figure, "Blast furnace material" and "External method H" are applied to all 8 types of girder data.
And are selected and entered.

The item "section" is a portion for arbitrarily inputting the size data of the H-section steel which is selected by the designer and seems to be appropriate. The web height "H", the flange width "B", the plate thickness of the web. “T1” and the thickness “t2” of the flange are input by the keyboard 1 or the like. Specifically, the input person is
The above H, B, t1, and t2 are input at a predetermined pitch p in the following numerical range.

700 ≦ H ≦ 900 mm p = 50 mm 300 ≦ B ≦ 400 mm p = 50 mm 12 ≦ t1 ≦ 19 mm p = 0.5 mm 25 ≦ t2 ≦ 40 mm p = 1 mm At this time, if the designer, the cross section of the H-shaped steel Although the size is well known, the subsequent processing can be continued with the manually input data as it is. However, in consideration of the case where the size is ambiguous, the calculation means 4 stores the "steel material size file" in the search file. It is also possible to retrieve the size data of the H-section steel close to the input data existing in the file by referring to. In this case, the "size search" button 46 is clicked after the entry in the "section" is completed.
When is clicked with the mouse 1, the calculation means 4 executes a size search process for extracting size data matching the input size data from the “steel material size file”.

While the inputted size data is arbitrary, the size of the manufactured H-section steel is standardized. "Compatible" basically means that the H-shaped steel that matches the input size data is a "steel material size file".
When it is obtained from the above, it means that the size data of the H-section steel is extracted, and when the dimensional data of the H-section steel which is not manufactured is input, the respective input data H, B, t1. , T2, which is larger and closer than t2, is extracted by referring to the "steel material equal size file".

Specifically, first, the H,
Of B, t1, and t2, t2 is first increased while increasing the pitch by 1 mm, and the search is performed to extract the closest one having a large size. Next, regarding the plate thickness t1 of the web, the one having the same size is searched on condition that the extracted t2 is satisfied, and if it does not exist, the search is performed while increasing the pitch by 0.5 mm, and the one having the largest size and closest To extract. Next, regarding the flange width B, the extracted t1,
Under the condition that t2 is satisfied, the same process is performed at a pitch of 50 mm to obtain the corresponding B. Finally, the web height H
As for the above, the same processing as above is performed at a pitch of 50 mm to obtain the corresponding H.

Explaining with the illustrated example, assuming that the input flange plate thickness is t2 = 27, for example, the data of manufactured products is searched for from the "steel material equal size file" with t2 = 28, Under the condition of t2 = 28, when the inputted web plate thickness is t1 = 12, the data existing from the “same file” is t1 =
No. 14 was searched and the entered flange width B = 30
For 0, such t1 and t2 are searched, and finally, when the inputted web height is H = 700, H = 700, provided that B, t1 and t2 are the above values. It can be understood that 800 H-section steels were searched.

Such processing is executed as processing for adapting the dimensions, and the size data of the H-section steel that is larger than the manually input size data and is the latest is extracted from the "steel material size file". Become. The reason why we chose a larger one is to consider safety in terms of structural strength.

As described above, in the size search process, the "steel material size file" is used to extract the H-section steels that fit, that is, match or are close in size.

Further, in relation to the item of "site" described above, the cross-sectional size of the girder can be input by changing the data at the span end and the span center. In consideration of the fact that the load acting on the beam end and the beam center part are generally different, and therefore the required strength is different, the cross-sectional size of the span center part is reduced compared to the span end part in the usual design. In view of the fact that the cost has been reduced, we are making it possible to reflect this in cost calculations.

Even in this case, since the designer is familiar with the cross-sectional size of the H-section steel, looking at the "cross-section" data for the "end" of the "site", the "center" It is only necessary to directly input the size-reduced data for the "cross-section" data of "." It is also possible to automatically retrieve the size data of shaped steel.

In this case, when the "center section 1 size DN (down)" button 44 is clicked with the mouse 1 after the entry in the section "section" is completed, the calculation means 4 causes the section 4 relating to "edge" to be "section". The size data of the H-section steel, which is one size smaller than the data, is extracted from the “steel material equal size file” to be the “center” “cross section” data.

In this processing, a plurality of data H, B, t1, t2 relating to the "cross section" of the "end portion" is used as a reference, and basically, the value of the flange plate thickness t2 is decreased to reduce the size by one size. It is designed to extract shaped steel. Specifically, t
The search is performed while decreasing 2 at a pitch of 1 mm, and the closest one having a small size is extracted. Next, regarding the plate thickness t1 of the web, the same size is searched for, provided that the extracted t2 is satisfied.
The search is performed while reducing the pitch at a 5 mm pitch, and the closest one having a small size is extracted. Next, regarding the flange width B, similar processing is performed at a pitch of 50 mm under the condition that the extracted t1 and t2 are satisfied, and the corresponding B is obtained. Finally, with respect to the web height H, the same processing as above is performed at a pitch of 50 mm to obtain the corresponding H.

In the illustrated example, the plate thickness t of the "end" flange
For 2 = 28, the size is sequentially reduced at a pitch of 1 mm, and t2 = 25 which is the one size down closest to t2 = 28
Are extracted, and t is assumed to satisfy this t2.
The result of extracting the H-section steel of 2 = 14, B = 300, and H = 800 is shown. In this way, the size data of the "cross section" of the girder, which also considers the "site" of the girder, is input.

By the above basic data input processing S10, the column of "cross section of girder" is filled with data according to the designer's intention. When the basic data input process S10 is completed in this way, the "data registration" button 4
Click 2 with mouse 1. By this operation, the processing shifts to floor assembly cost calculation processing S20, and the display 3
The display changes as shown in FIG.

In addition to displaying, data input including data selection is performed by the data input means 1.

Candidates are listed at the left end, and the items "beam" and "stud bolt" are displayed. In the item of "beam", "H", "B", "t1", "t2" are displayed to input the sizes of "small beam", "son beam" and other stiffening materials. In addition, the "joint type" is shown in selectable forms. In the item "stud bolt", "diameter" and "type" are displayed in a selectable form. On the other hand,
For each item of "Height" and "Pitch", the initial value of "Large beam stud-related initial value" is read from the above-mentioned "Initial value data" and displayed, and in addition to this, the designer arbitrarily sets it. You can also enter numbers.
Here, the “type” relates to whether the stud bolts are arranged in one row (single) or two rows (double) (see the explanation of the initial value data).

When the input of the required data to the blank is completed as described above, the process of inputting the data regarding the floor beam is completed. When the floor beam data input process S22 is completed, the "input complete" button 48 is operated. By this operation, the processing shifts to the floor assembly data input processing S23, and the display on the display 3 is switched as shown in FIG.

In the floor assembly data input processing S23, as in the floor beam data input processing S22, various data relating to the floor assembly construction are read out from the search file by the calculating means 4 for four types of candidates and displayed. A process of inputting data input including selection of displayed data by the data input means 1 is executed.

Candidates are listed at the left end, and on the other hand, the item of "reinforcing bar", the item of "wire mesh", and the item of "concrete" are displayed. In the "reinforcing bar" item, it is divided into the "short side" direction and the "long side" direction, and the "diameter" and "pitch" are individually input for each of the "upper end bar" and the "lower end bar". Has become. In the "wire mesh" item, the size is to be entered. In the item "concrete", "type" and "reference strength" are to be input. And here, except for the "pitch" of "reinforcing bar" that is manually input, all other items are displayed in a selectable form, and it is possible to input either manually or manually. ing.

When the input of the required data to the blank is completed as described above, the process of inputting the data regarding the floor assembly is completed. When the floor group data input process S23 is completed, the "input completion calculation start" button 52 is operated. By this operation, the process is the floor assembly cost calculation process S
Move to 24.

In the floor set cost calculation process S24, unit price data corresponding to the above-mentioned various material data and construction data regarding the floor set input so far are extracted from the search file of the storage means 2 and various calculation processes are performed. I am supposed to do it. The contents of this arithmetic processing will be described with reference to FIG. 14 showing the result.

It is calculated by that. The item "cost comparison (%)" is a relative value of the "total floor assembly cost" of each candidate.

On the other hand, in the lower column, various individual costs are calculated for the four types of candidates, "Study No.", and the individual costs are bar-graphed for comparison. Regarding the calculation of individual costs, each unit price data corresponding to material data and construction data is divided into the following costs and calculated. In other words, the total of these individual costs is the above "total beam construction cost".

[Calculation formula of individual cost] -Beam production cost = Steel material cost + Sub-material cost + Factory processing cost + Factory welding cost + Rust prevention cost + Transportation cost + ...- Deck construction cost = Material cost + Transportation cost + Installation cost + …… ・ Reinforcement construction cost = Material cost + Transportation cost + Installation cost + …… ・ Concrete construction cost = Material cost + Placing and leveling labor cost +…
… ・ Fireproof coating cost = material cost + spraying construction cost + …… ・ Beam site construction cost = stud dowel striking cost + bolt main tightening cost + …… ・ Temporary construction cost = lease cost + maintenance cost + labor relocation cost + …… In this embodiment, in the floor assembly cost calculation process S20,
The computing means 4 accepts four types of different input data, and executes the above-mentioned respective processes by using the corresponding material data, construction data and unit price data for each of the plurality of input data, and the plurality of input data. The display means 3 is configured to display a list of a plurality of results in the form of a table and a graph, and even for one design object, the material of the pillar or the beam, the structure of the floor, or the pillar and the beam can be changed. If the joining method or floor construction method is changed, the material and construction technology used will change, the material data etc. to be read from the search file and unit price data will change, and the construction cost will also increase or decrease. Since it is possible to calculate the construction cost of multiple candidates, it is possible to easily create useful materials for comparative evaluation.

Since the results corresponding to each of the obtained plurality of input data are displayed on the display means 3 as a list in the table format and the graph format as described above, the obtained results are made easy to see and compared. Can be facilitated.

In this way, the floor assembly cost calculation processing S20

A plurality of different construction costs of the design object are calculated by combining and calculating. The result of the calculation process will be described according to the display on the display 3 of FIG. 18 in which the construction cost calculation result display process S42 is executed.
