Description

CONSTRUCTIONAL SYSTEM FOR PROVIDING STRUCTURAL ARRANGEMENTS TO BUILDINGS TECHNICAL FIELD The present invention relates to a constructional system for creating and providing structural arrangements to buildings, and facades of buildings in particular.

BACKGROUND ART Constructional work related to raising and refurbishing buildings of different types involves alot of work in a plurality of technical field, such as architecture, construction planning andassembly. For certain types of constructional work, said different types of technical fields arenot always correlated in the best possible manner, which may result in non-optimal conditionsfor other areas. For example, if a façade is to be refurbished for a building having a plurality offloors, a construction scaffolding may have to be raised at said façade. Such a scaffolding willusually need to be drilled and secured into the façade for support and security. Suchoperations may be problematic depending on the type of building and may not be desired to do for the visual appeal as well.

Other types of structural arrangements may have other related problems, which demandsother solutions to handle, wherein a plurality of system and devices may be needed toperform a plurality of constructional operation to a building. This often leads to larger than needed material costs, and longer time to complete the work or other. lt is thus desirable to streamline such work by means of an effective and beneficial constructional system that alleviates issues with prior art.

SUMMARY OF THE INVENTION Despite prior art there is a need to develop an improved constructional system, which may beused to provide structural arrangements to buildings and facades thereof. There is also a needto develop such a constructional system, which is possible to use for both temporary and permanent structural arrangements in an efficient manner. There is further a need to develop jjzo 2a method for arranging structural arrangements to a building using such a constructional system, and to use said structural arrangement in a plurality of ways.

An object of the invention is thus to provide an improved constructional system, which may beused to provide structural arrangements to buildings and facades thereof. Another object isrespectively to provide such a constructional system, which is possible to use for bothtemporary and permanent structural arrangements in an efficient manner. An even furtherobject is to provide a method for arranging structural arrangements to a building using such a constructional system, and to use said structural arrangement in a plurality of ways.

According to a first aspect, a constructional system comprising a framework and a plurality ofcoupling elements is provided. The framework and coupling elements configured tobe coupled to each other. The framework Pafayßcompriseg a circumferential front frame, twoside frames, arranged at opposite sides of said front frame and extending perpendicularlyaway therefrom, a top frame and a bottom frame, arranged at a top side and a bottom side ofthe front frame respectively, and extending perpendicular away therefrom, in the samedirection as the side frames. The framework :nav-further comprise§ at least four couplingbeams, extending in parallel with the side frames, the top frame and the bottom frame. Eachcoupling element æræfafycomprises an anchoring portion, configured to be attached to or in aconstructional portion or element of a building, and at least one inner extending channel,which channel is arranged to be form fitted with a coupling beam of the framework.Furthermore, the constructional system Paay-ëeæggconfigured to provide a structuralarrangement to a façade of a building by means of attaching a plurality of coupling elementsto said building, wherein the anchoring portions are fixedly attached to the building so thatthe at least one inner channel is reachable from said façade. At least one framework may thenbe coupled to the coupling elements by means of the coupling beams so that the at least one framework extends out from said façade and constitutes the structural arrangement thereto.

This has the advantage that a versatile constructional system is provided, which system maybe used to provide a plurality of different types of structural arrangements to a building. Bymeans of incorporating and/or attaching the coupling elements in a predetermined pattern ina façade of a building, said coupling elements may distribute the weight ofthe framework over the façade, and its surrounding structural components, of the building in an efficientmanner. A structural arrangement provided to a building by means ofthe disclosed systemmay thus provide a framework that may be complemented in various ways, wherein thebottom frame may constitute a basis for a floor structure, the side frames may constitute abasis for wall structures and the top frame may constitute a basis for a ceiling and/or roofstructures. The framework may thus provide structural support to be used and utilized as awide range of arrangements extending out from a façade of such a building, without any needfor additional structural components such as vertically oriented beams or similar that could provide support from a ground level adjacent such a façade.

According to an aspect, the structural arrangement provided by the constructional systemmay be temporary attached to a building so as to provide a temporary construction scaffolding thereto.

This has the advantage that a construction scaffolding may be attached to a building, either atthe time of raising said building, or at a later point in time for a refurbishing ofthe façade ofsaid building or similar, without the need to perform any sort of foundation work at groundlevel adjacent said building. The construction scaffolding provided may thus be both faster andeasier to provide to a building, and at the same time avoid unnecessary destructive work toand in the vicinity of said building. The coupling elements being incorporated in, or arrangedto a façade may further be utilized in additional manners after the scaffolding is removed. Bymeans of having said coupling elements arranged in a facade, providing coupling options tosuch a façade, said façade will not be further damaged by drilling and anchoring of a prior artscaffolding solution. Thereby the structural integrity of such a façade may be upheld in a bothpractical and aesthetic pleasing manner, as the pattern of coupling elements provide couplingoptions over said façade in a repeated pattern, wherein each coupling element may be provided to a façade in a controlled manner.

According to an aspect, the structural arrangement may be fixedly attached to a building so as to provide a permanent balcony framework thereto.

This has the advantage that a balcony framework may be attached to any position of a façade,which position corresponds to the available options determined by the predetermined patternin which the coupling elements are arranged in the facade. This further makes assembly of a balcony easier, faster and more cost effective for a building in which coupling elements of thesystem are in place within the façade of said building. Furthermore, ifthe framework has beenused as a scaffolding for assembly of, or refurbishing of, such a building, the same frameworkmay thus be left in place in positions where balconies are to be positioned. The sameframework may hence be used for both of the mentioned structural arrangements, whichsaves assembly time and lower material costs as the same structure provides a plurality of functions to such a building.

According to an aspect, at least one coupling element and the framework may furthercomprise an electrical socket and plug respectively, wherein coupling of said socket and plugmay be achieved automatically when the two structural elements are coupled to each other,and wherein the framework may further comprise an electric cable arranged therein, whichcable is connected to a framework socket, arranged at a predetermined position ofthe framework.

This has the advantage that electricity may be provided to the structure in an easy andefficient manner. Regardless of the intended usage ofthe framework, such as a scaffoldingand/or a balcony for example, electricity may be a beneficial addition to such a structure. Bymeans of incorporating such a feature within the framework, no external cables need to beadded to such structures later on, which provides both an increased safety due to eliminatingthe risk oftripping on externally provided cables, and also provides a sleek and pleasingesthetical appearance for the structure and the building to which it is arranged. Even further,the socket arranged within the coupling elements may also be utilized for other additionalusages if the framework is not intended to be used as a balcony when assembly is completed.By means of having an available socket therein, the coupling elements may be used asattachment point for lighting fixtures or armatures and similar, or simply be used as an externally positioned socket for coupling to electrical equipment of various kinds.

According to an aspect, each coupling element may further comprise a plurality of innerextending channels, arranged to accommodate for coupling to a plurality of coupling beams of frameworks.

This has the advantage that the number of coupling elements needed may be decreased,wherein material costs are lowered for a building comprising such coupling elements. A single coupling element may instead accommodate a plurality of frameworks, which then may 5extend at different directions from the coupling element. This feature also makes positioningof two adjacent frameworks more rigid and reliable in accuracy, as the risk of misalignment oftwo single-channel coupling elements to accommodate for one framework each is eliminated from a building process.

According to an aspect, a method for arranging a construction scaffolding to a façade of abuilding using a constructional system according to the disclosure is provided. The methodnaayecompriseg the steps of: a) arranging a plurality of coupling elements in a predeterminedpattern at a façade of a building, b) inserting at least one framework into the arrangedcoupling elements, and c) arranging temporary scaffolding components to the at least one framework.

This has the advantage that a very simple and straightforward method is provided, whichmethod may be used to arrange a building scaffolding to a building, wherein said scaffolding isattached and supported solely by horizontal beams and wherein no ground support is needed for said scaffolding.

According to an aspect, the method may further be expanded for construction of a balcony tosaid façade ofthe building, wherein the method further comprises the steps of: d) removingthe temporary scaffolding components from the at least one framework, and e) arranging additional structural elements to the framework so as to provide a balcony.

This has the advantage that the method may provide a balcony to a building in a fast andefficient manner, wherein lesser step are needed for removal of the scaffolding, and toprovide a basic framework of a balcony to such a building. Such a method may thus lowercosts accompanied to completing a building in a plurality of ways, and especially if said building is to be provided with at least one balcony.

According to an aspect, a construction scaffolding is provided. The construction scaffoldingcomprising a plurality of coupling elements arranged in a building, and at least one frameworkthat is configured to be inserted into said coupling elements. Wherein the framework oftheconstructional system is configured to be left remaining on said façade so as to constitute a permanent structural framework of a balcony to said building.This has the advantage that the framework of a construction scaffolding may be used toprovide a permanent structural framework of a balcony to a building in a manner which savesa lot of time, work and unnecessary wasted material. |nstead of having to remove ascaffolding, or parts thereof, arranged to a building, and then start building a balcony, saidscaffolding or parts thereof may instead be left remaining on the building wherein a lot of the initial work of arranging a balcony thereto is already achieved.

DETAILED DESCRIPTIONThe description of the various features, and modifications thereof, according to the disclosure will herein be described in more detail. It is thus to be understood that embodiments 7comprising any of the described feature or a combination of features may be assembled in accordance with the description herein.

Fig. 1 shows a framework 1 and a coupling element 3 of a constructional system 5 in aperspective view according to an embodiment. The constructional system 5 ﬁæïfcomprise aframework 1 and a plurality of such coupling elements 3, wherein only one coupling element 3is depicted in fig. 1 for the sake of simplicity. The framework 1 and coupling elements 3 areconfigured to be coupled to each other so as to provide a structural arrangement. Theframework 1 rn-.wcompriseg a plurality of individual frames, coupled to each other in a fixedmanner. The plurality of frames maybefargncomprised of a circumferential front frame 7, twoside frames 9, arranged at opposite sides of said front frame 7 and extending perpendicularaway therefrom, a top frame 11 and a bottom frame 13, arranged at a top side and a lowerside of the front frame 7 respectively, and extending perpendicularly away therefrom, in thesame direction as the side frames 9. The different individual frames 7, 9, 11, 13 may, asdepicted in fig. 1, have specific designs to provide different types of functions and allow ofaccess to different areas of the framework 1. The framework 1 and the frames 7, 9, 11, 13thereof may be manufactured in various materials, however metal if most likely preferred toallow for large loads and forces to be subjected to the framework 1 when assembled. Thecircumferential front frame 7 is herein depicted as solely circumferential around an encircledopen area therein, wherein corners ofthe front frame are rounded in their design. Therounded corners may allow for a better distribution of forces within the construction withoutunnecessary sharp turns that may have a higher concentration of deformation due to forming,and to lower the amount of welding or similar manufacturing methods that may be needed toprovide sharp corners. The front frame 7 may also have additional frame elements addedthereto, which additional elements may, for example, extend horizontally over the open areaof the frame 7, without deviating from the scope of protection. The side frames 9 Pefavfcomprise a sideways directed U-shape, further provided with an additional angled structuralelement 15, which is arranged between an upper portion 17 and a side portion 19 of said U-shaped side frame 9. The angled element 15 is arranged thereto to provide an increasedstrength and stability to the completed framework 1. The top frame 11 and the bottom frame13 mayßas depicted herein beßﬁsimilar in shape and design, and both mawcomprise a circumferential portion 21 and an inner structural network portion 23 each. The frameworkmay further comprise at least four coupling beams 25, extending in parallel with the sideframes 9, the top frame 11 and the bottom frame 13, herein extending from edges defined byinterconnections of said frames 9, 11, 13, said coupling beams 25 may further comprise anouter circumference having a certain shape and design. The relative sizes of the couplingbeams 25 and the top and bottom frames 11, 13 are, as depicted in fig. 1, designed to definean open upper area and an open lower area within the framework 1. The functionality ofthese two open areas will be explained in more detail later in the disclosure. The couplingelement 3 nﬁay-comprises an anchoring portion 27, configured to be attached to or in aconstructional portion or element of a building, and at least one inner extending channel 29,arranged opposite in a lengthwise direction to the anchoring portion 27. The inner channel 29may comprise an inner circumference that is arranged to be form fitted with the outercircumference ofthe coupling beams 25 of the framework 1. The coupling elements 3 may beprovided with a predetermined set inner length 31, which inner length 31 provides a setdistance the coupling beams 25 may be inserted into such a channel 29. The previouslymentioned open areas of the top and bottom frames 11, 13 may thus be defined anddetermined by means of sizes ofthe top and bottom frames 11, 13, the inner length 31 of theinner channel 29 of the coupling elements 3 and the coupling beams 25, wherein the openareas will correlate to the area there in between. The anchoring portion 27 may be designeddifferently depending on what type of building or structure they are intended to be positionedwithin. Known and conventional techniques within the art may be used to arrange and fix saidanchoring portions 27 reliably within a façade of a building. lt should be mentioned howeverthat the coupling elements 3 may be incorporated into other structural elements of a buildingat a prior point in time, if it is known the constructional system according to the disclosure isto be used at said building. There are also certain building systems that may be even moresuited for having such coupling elements 3 incorporated therein, wherein the couplingelements 3 according to this disclose may in part be parts of certain structural elements ofother constructional modular systems. As an example, certain types of prefabrication buildingsystems may have horizontal elements in which the coupling elements 3 according to thisdisclosure herein may be coupled to as part of said prefabrication system, wherein thecoupling elements 3 will be a part ofthe building raised with such a prefabrication system,when said building is fully assembled. Furthermore, the constructional system 5 may be configured to provide a structural arrangement to a façade of a building by means of attaching 9a plurality of coupling elements 3 to said building, wherein the anchoring portions 27 arefixedly attached to the building so that the at least one inner channel 29 is reachable from saidfaçade. Wherein at least one framework 1 is coupled to the coupling elements 3 by means ofthe coupling beams 25 so that the at least one framework 1 extends out from said façade and constitutes the structural arrangement thereto.

Fig. 1 only depicts one coupling element 3, wherein it should be obvious that additionalcoupling elements are to be perceived to be positioned in empty corners of a polygonal unit33, which is depicted in dashed lines in fig. 1. The shape of a predetermined pattern in whichthe coupling elements 3 are arranged to a building, coupled with the designs of the frames 7,9, 11, 13 constituting the framework 1, and the coupling elements 3 and the anchoringportions 27 thereof will, when used in combination, provide a rigid and reliable structuralarrangements that may extend out from facades of buildings. Such structural arrangementsmay be subjected to large loads and forces, which loads and forces are distributed over the building and its façade in an efficient manner.

The constructional system 5 may be used to provide a structural arrangement, which may betemporary attached to a building, so as to provide a temporary construction scaffoldingthereto. Thereby a scaffolding may be attached to a building without the need for support ofsaid scaffolding at ground level adjacent said building. The structural arrangement provided bymeans of the constructional system 5 may need to be complemented with additional details,such as ladders, connecting bridges, fall protection, flooring, bridges, ceilings and walls andsimilar, but the basis for providing the mechanical integrity ofthe arrangement is provided solely from the framework 1 when securely attached to a building.

The constructional system 5 may be used to provide a structural arrangement to a building,wherein the structural arrangement is fixedly attached to the building so as to provide apermanent balcony framework thereto. Similarly to when using the system 5 to provide ascaffolding, the structure may need to be complemented with additional elements before afully functional balcony is achieved, but the structural framework providing the mechanical integrity is provided by means of the attached framework 1 of the constructional systemFor both of the usages described above, additional fasteners and/or fastening method may need to be used to achieve a desired stability and functionality to said structures. Screws or other similar fasteners may be used to provide a temporary and reversible attachmentbetween the framework 1 and the coupling elements 3, when the system 5 is used to providea scaffolding. For a balcony construction, screws or other such fastening elements may also beused, but options such as welding or other types of more rigid attaching method may also beused, either on their own or as a complement to reversible attaching methods and/or elements.

As should be obvious, the system 5 may thus be used to provide both a scaffolding and abalcony to a building, by means of using the same framework 1 for both said purposes atdifferent points in time. A plurality of frameworks 1 may be temporary attached to a buildingto provide a scaffolding, either as part ofthe construction of said building, or at a later point intime for a refurbishing of said building. When the constructional work utilizing such ascaffolding is completed, the frameworks 1 in positions for use of balconies may then be keptin place and those not desired to keep may be removed and used at another subsequentbuilding and/or construction site. The frameworks 1 remaining on the building may becomplemented with regards to their attachment to the coupling elements 3 and the building, and the balconies may be completed to achieve their intended design.

Fig. 2a-c show different coupling elements 3 in perspective views according to differentembodiments. ln short fig. 2a shows a single-channel 29 coupling element 3, fig. 2b shows amultiple-channel 29 coupling element 3, and fig. 2c shows a coupling element 3 provided withan internal electrical socket 33. lt should also be mentioned that the coupling elements 3 areto be perceived as schematic in their depiction, wherein specifics regarding their design suchas size, shape and proportions may be modified without deviating from the scope of protection defined throughout the disclosure.

As stated, fig. 2a shows a single-channel 29 coupling element 3, which thus may comprise asingle inner channel 29, arranged to house a single corresponding coupling beam 25 of aframework 1. The inner channel 29 may comprise an inner circumference, designed to fit withan outer circumference of a coupling beam 25 of a framework 1 of the constructional system5. The inner channel 29 may further comprise a predetermined inner length 31, which length31 defines how far into the inner channel 29 a coupling beam 25 may be inserted. When using the constructional system 5 to provide a structural arrangement to a building, it is thus alwaysknown how far out from the building the framework 1 of the system 5 will extend, as long asan outer edge 35 of the coupling elements 3 is arranged within the façade of the building in acontrolled manner. The coupling element 3 mafæfurther comprises an anchoring portion 27,which extends away from the inner channel 29 in a direction opposite of said inner channel29. The anchoring portion 27 is arranged to be inserted in a wall or other similar rigid part of abuilding, so as to be firmly and reliably positioned within a façade of said building. Dependingon the type of building, or the type of method a building is raised with, the anchoring portion27 may be modified to conform in the best possible manner with the structural components ofsaid building. lt is also possible to further modify the possible ways to arrange the anchoringportion 27 of a coupling element 3 by means of adding additional adapter elements, arrangedto fit with a certain design ofthe anchoring portion 27, and also fit with a certain type ofmaterial, design or element of a specific building and/or building type. The anchoring portion27 may also be increased in length by a large margin (compared to schematic representationdepicted in fig. 2a) if it is more suitable for a specific constructional solution related to aspecific building. The anchoring portion 27 is to be the part of the coupling element 3 thatprovides a reliable attachment to a building, however a circumferential wall 37 enclosing theinner channel may of course also be attached to the building and its structural elements if desired.

As stated, fig. 2b shows a multiple-channel 29 coupling element 3. The multiple-channel 29coupling element 3 as depicted therein comprises a total of four inner channels 29, arrangedin a quadrant each within the space encircled by the circumferential wall 37 of the couplingelement 3. Each such inner channel 29 may thus be used to receive and hold one couplingbeam 25 of a framework 1 each. This may be utilized to arrange a plurality of frameworks 1adjacent each other in a reliable and precisely repeatable manner. Other than the differencebetween the coupling element 3 as depicted in fig. 2a, having one inner channel 29, and thecoupling elements 3 as depicted in fig. 2b, having four inner channels 29, the two depictedcoupling elements 3 may be perceived as similar to each other, wherein the description ofthecoupling element according to fig. 2a may be thought of as describing the coupling element 3according to fig. 2b as well, with regards to other parts ofthe two respective coupling elementsAs also previously stated, fig. 2c shows a coupling element 3 provided with an internalelectrical socket 33. Also shown in fig. 2c is part of a corresponding coupling beam 25. Theconstructional system 5 may comprise a plurality of coupling elements 3, wherein at least onecoupling element 3 and the framework 1 further comprises an electrical socket 33 and plug 39respectively. Coupling of said socket 33 and plug 39 may be achieved automatically when thetwo structural elements 3, 25 are coupled to each other, which is provided by means of thegeometries of said components and how they are arranged to fit in only one orientationrelative each other. The framework 1 may further comprise an electric cable 41 arrangedtherein, which cable 41 is connected to a framework socket (not shown in fig. 2c), arranged ata predetermined position ofthe framework 1. The coupling element 3 as depicted in fig. 2ccomprises, similar to the coupling element 3 depicted in fig. 2b, four inner channels 29,wherein the internal electrical socket 33 only is arranged in one of said four inner channels 29.As one framework 1 corresponding to this design is to be perceived as comprising fourcoupling beams 25, each framework 1 may thus be provided with electricity from solely one ofsaid four coupling beams 25. However, it is of course possible to arrange internal electricalsockets 33 in any and/or all of the inner channels 29 of a coupling element 3 if it is deemed to be needed for a specific design and/or utilization of the constructional systemAll ofthe different embodiments of the coupling elements as depicted in figs. 2a-c are to beperceived as manufactured in a robust and strong material, which may be a metallic materialsuch as a hardened steel, a stainless steel or a strong metallic alloy, a ceramic material, acomposite material or other. The coupling elements 3 may also be provided with pre-drilled holes so as to receive fastening elements or similar in a more convenient manner.

Fig. 3a-b show a framework 1 of the constructional system, inserted into coupling elements 3arranged in a façade of a building 43, in a top down view and a side view respectively according to an embodiment.

Turning the attention to fig. 3a, which depicts said framework 1 in a top down view, it isclearly seen that the top frame 11 of the framework 1 is situated at a distance 45 from thefaçade ofthe building 43. The open area there between provides the option of arrangingflights of stairs or similar within this open area. That possibility thus makes it possible to connect a plurality of vertically adjacent frameworks 1 with each other so as to provide avariety of structural arrangements to the building 43. lf used as a temporary constructionscaffolding, stairs between different floors are of course needed to be able to providemovability between different floor levels within said scaffolding. lf the framework 1 instead isto be used as a permanent structural arrangement, such as a balcony, additional floorelements and/or roof elements may easily be arranged to cover the open area. The framework1 may also be part of other types of permanent attached structures, such as an exteriorlypositioned corridor or similar, which may be function as a substitute for internally positionedstairwells, fire exit stairs or similar in a building with a plurality of floors. For such cases theopen area may thus be highly beneficial as the framework provides the option to do so without the need to remove pieces and/or parts of the frameworksln a similar manner the side view ofthe framework 1, as depicted in fig. 3b, clearly shows thatthe side frame 9 provides an open space therein as well. When the framework 1 is arranged tothe building 43 to be part of a temporary scaffolding, said open space provides an easy accessto horizontal movability between correspondingly horizontally adjacently arrangedframeworks 1. The same holds true if the framework 1 is to be parts of an arrangement such as an exteriorly positioned corridor or similar, which was described with reference to fig. 3a.

Fig. 4 shows a building 43 provided with a plurality of structural arrangements arrangedthereto by means of using the constructional system 5 according to an embodiment. Thebuilding 43 as depicted is not fully completed, but is to be perceived as a building 43 underconstruction, wherein a total of nine room units are arranged in three floors of said building43. As is seen in the depiction, the frameworks 1 have been provided with temporaryscaffolding components so as to provide more utility and functionality to the arrangements,which in this state depicted is to be perceived as a construction scaffolding 47. Floor elements49 are provided to each structural arrangement at the façade to provide an easier to use andstable walking area for construction workers working on the building 43. Stair units 51 havebeen provided to two structural arrangements so as to provide vertical movability within thescaffolding 47. One of the inner channels (inner channels and features comprised therein arenot seen in fig. 4 however) of a coupling element 3, and its corresponding framework 1coupled thereto is herein further provided with electrical socket 33 and plug 39 respectively,which are coupled to each other automatically when the framework 1 was inserted into the inner channel 29 as previously described with reference to fig. 2c. The framework 1 further 14comprises an electric cable 41 arranged therein, which cable 41 is connected to a frameworksocket 53, arranged at a predetermined position of the framework 1. As should be obvious,the electrical components described herein may be provided to each and every framework 1of the depicted system 5, or to a selected plurality of frameworks 1 as well. Furthermore, theframework socket 53 may also be moved to other parts of the framework 1 if deemed more suitable for specific application of the constructional systemThe coupling elements 3 according to fig. 4 is to be perceived as being similar to theembodiments ofthe coupling elements 3 as depicted in figs. 2b and 2c, all comprising fourinner channels 29 therein. lt may also be seen in fig. 4 how the coupling elements 3 arearranged relative the building 43 and its façade. The façade of this building 43 is provided witha plurality of façade elements 55, which are arranged to the room units ofthe building 43. Thecoupling elements 3 may then be arranged so as to sit flush with an outer surface of saidfaçade elements 55 so as to provide a correct alignment between the building 43 when thefaçade is completed, the coupling elements 3 and the frameworks 1 of the constructionalsystem 5. Additional fasteners and/or fastening methods may also be used to securely attachthe coupling elements 3 to the building 43 before the façade elements 55 are put in place.Thereby such fasteners and fastening methods may be hidden from view when the buildingis fully assembled.

Furthermore, it may herein also be seen that the coupling elements 3 may be attached tostructural elements 57 of the building system used to raise the building 43 in question. Thebuilding 43 herein is to be perceived as being assembled by means of a specific prefabricationbuilding system, which system comprises a specially designed structural element 57 that isarranged between the room units of said system. By means of incorporating the couplingelements 3 into such structural elements 57 prior to assembly ofthe building 43 is initiated,the two systems, namely the prefabrication building system and the constructional system 5according to the disclosure herein, may be integrated into each other so as to provide an even more efficient and faster constructional method for raising a buildingThe construction scaffolding depicted in fig. 4 may thus be described as comprising a pluralityof coupling elements 3 arranged in a building 43, and a plurality of frameworks 1 that are configured to be inserted into said coupling elements 3, wherein the coupling elements 3 and the frameworks 1 being provided by means of the constructional system 5 according to thedisclosure. The frameworks 1 of the scaffolding 47 and thus also the constructional system 5 bywhich they are provided, may further be configured to be left remaining on said façade so as toconstitute a permanent structural framework of a balcony to said building 43. Thus, any one ofthe frameworks 1 as depicted in fig. 4 may be opted to be left attached to the building 43 asshown. Correspondingly, any framework 1 not to be used as part of another type of structuralarrangement may also be removed from the building 43, as commonly performed for a prior artscaffolding solution. The frameworks 1 decided upon to be kept however may simply to becomplemented with predetermined additional balcony components so as to complete a balconyassembly for each and every one of the position where such is desired, and to achieve a specificbalcony design thereto. The floor elements 49 may be part of the balcony assembly as they are,or they may be removed and replaced with other types of floor elements to complete theassembly. The stairs 51 may or may not be removed, depending on the type of balcony and/orthe type of building that is to be assembled. lf the different floors of the building 43 are toconstitute separated floors with individual balconies thereto, the stairs 51 would be mostsuitable to remove. But if the balconies as to constitute parts of exteriorly positioned corridorsor similar, the stairs 51 may be kept in placed so as to provide the basic components of an exteriorly positioned stairwell arrangement joining the different floors together. façade elements Fig. 5 shows a flowchart of a method for arranging a constructionalscaffolding to a façade of a building according to an embodiment. The method shown bymeans of the flowchart is to be perceived as using a constructional system according todisclosure, wherein the method rnayßcompriseg the steps of: a) arranging a plurality ofcoupling elements in a predetermined pattern at a façade of a building, b) inserting at leastone framework into the arranged coupling elements, and c) arranging temporary scaffoldingcomponents to the at least one framework. Step a) may be performed in advance and/or incombination with parts of assembly of said building. Thus, step a) is to be perceived as beingperformed in a plurality of ways, such as arranging all coupling elements to an already existingfaçade, or arranging the coupling elements bit by bit as the construction/assembly of thefaçade is being performed to name a few examples. The coupling elements may also bearranged in or at specific constructional elements that are to line up with the façade in a proper manner, wherein assembly of the building and/or façade thereof positions the couplingelements into their correct locations as a natural step of the assembly of building.Furthermore, the steps of the method may also be performed as sub-steps of assembly for aspecific floor of a building, wherein the steps a), b) and c) are performed in that order for onecurrent floor being assembled/built, wherein the steps then are repeated for the next floor ofthe building, and so on until all floors of the building are assembled. The temporary scaffoldingcomponents as mentioned with reference to step c) may be components such as floorelements, wall elements, roof elements, stairs and steps, additional safety rails, or othersimilar constructional auxiliary components needed to achieve a safe and reliable construction scaffolding.

Fig. 6 shows a flowchart of a method for further construction of a balcony to said façade of abuilding provided with a construction scaffolding according to an embodiment. Thus, themethod shown in the flowchart of fig. 6 is to be perceived to be used on a building alreadyprovided with a construction scaffolding by means of the constructional system according tothe disclosure. The starting point for the method shown in fig. 6 is thus the end result ofthemethod as shown in fig. 5, wherein further construction of a balcony to said façade of thebuilding is to be performed. The method may comprises the steps of: d) removing thetemporary scaffolding components from the at least one framework, and e) arrangingadditional structural elements to the framework so as to provide a balcony. Step d) may ofcourse not necessary mean the removal of all components, if some specificcomponent/components are usable for the construction of the balcony, they may of course beleft remaining on the structural arrangement. Furthermore, the term balcony is herein to beinterpreted in a broad sense, and may be mean a single balcony, a larger set of severalbalconies, or a similar structure arranged at a façade of a building, such as an exteriorly positioned corridor and/or stairwell or similar.
