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 a lot of work in a plurality of technical field, such as architecture, construction planning and assembly. For certain types of constructional work, said different types of technical fields are not always correlated in the best possible manner, which may result in non-optimal conditions for other areas. For example, if a fagade is to be refurbished for a building having a plurality of floors, a construction scaffolding may have to be raised at said fagade. Such a scaffolding will usually need to be drilled and secured into the fagade for support and security. Such operations 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 demands other solutions to handle, wherein a plurality of system and devices may be needed to perform 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.

It 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 be used to provide structural arrangements to buildings and facades thereof. There is also a need to 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 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.

An object of the invention is thus to provide an improved constructional system, which may be used to provide structural arrangements to buildings and facades thereof. Another object is respectively to provide such a constructional system, which is possible to use for both temporary and permanent structural arrangements in an efficient manner. An even further object 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 of coupling elements is provided. The framework and coupling elements may be configured to be coupled to each other. The framework may comprise a circumferential front frame, two side frames, arranged at opposite sides of said front frame and extending perpendicularly away therefrom, a top frame and a bottom frame, arranged at a top side and a bottom side of the front frame respectively, and extending perpendicular away therefrom, in the same direction as the side frames. The framework may further comprise at least four coupling beams, extending in parallel with the side frames, the top frame and the bottom frame. Each coupling element may comprise an anchoring portion, configured to be attached to or in a

constructional 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 may be configured to provide a structural

arrangement to a fagade of a building by means of attaching a plurality of coupling elements to said building, wherein the anchoring portions are fixedly attached to the building so that the at least one inner channel is reachable from said fagade. At least one framework may then be coupled to the coupling elements by means of the coupling beams so that the at least one framework extends out from said fagade and constitutes the structural arrangement thereto.

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

According to an aspect, the structural arrangement provided by the constructional system may 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 at the time of raising said building, or at a later point in time for a refurbishing of the fagade of said building or similar, without the need to perform any sort of foundation work at ground level adjacent said building. The construction scaffolding provided may thus be both faster and easier to provide to a building, and at the same time avoid unnecessary destructive work to and in the vicinity of said building. The coupling elements being incorporated in, or arranged to a fagade may further be utilized in additional manners after the scaffolding is removed. By means of having said coupling elements arranged in a facade, providing coupling options to such a fagade, said fagade will not be further damaged by drilling and anchoring of a prior art scaffolding solution. Thereby the structural integrity of such a fagade may be upheld in a both practical and aesthetic pleasing manner, as the pattern of coupling elements provide coupling options over said fagade in a repeated pattern, wherein each coupling element may be provided to a fagade 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 fagade, which position corresponds to the available options determined by the predetermined pattern in 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 the system are in place within the fagade of said building. Furthermore, if the framework has been used as a scaffolding for assembly of, or refurbishing of, such a building, the same framework may thus be left in place in positions where balconies are to be positioned. The same framework may hence be used for both of the mentioned structural arrangements, which saves 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 further comprise an electrical socket and plug respectively, wherein coupling of said socket and plug may 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, which cable is connected to a framework socket, arranged at a predetermined position of the framework.

This has the advantage that electricity may be provided to the structure in an easy and efficient manner. Regardless of the intended usage of the framework, such as a scaffolding and/or a balcony for example, electricity may be a beneficial addition to such a structure. By means of incorporating such a feature within the framework, no external cables need to be added to such structures later on, which provides both an increased safety due to eliminating the risk of tripping on externally provided cables, and also provides a sleek and pleasing esthetical 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 additional usages 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 as attachment 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 inner extending 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 extend at different directions from the coupling element. This feature also makes positioning of two adjacent frameworks more rigid and reliable in accuracy, as the risk of misalignment of two 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 fagade of a building using a constructional system according to the disclosure is provided. The method may comprise the steps of: a) arranging a plurality of coupling elements in a predetermined pattern at a fagade of a building, b) inserting at least one framework into the arranged coupling 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, which method may be used to arrange a building scaffolding to a building, wherein said scaffolding is attached 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 to said fagade of the building, wherein the method further comprises the steps of: d) removing the 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 and efficient manner, wherein lesser step are needed for removal of the scaffolding, and to provide a basic framework of a balcony to such a building. Such a method may thus lower costs 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 scaffolding comprising a plurality of coupling elements arranged in a building, and at least one framework that is configured to be inserted into said coupling elements. Wherein the framework of the constructional system is configured to be left remaining in the fagade of said building 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 to provide a permanent structural framework of a balcony to a building in a manner which saves a lot of time, work and unnecessary wasted material. Instead of having to remove a scaffolding, or parts thereof, arranged to a building, and then start building a balcony, said scaffolding 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 DESCRIPTION

The 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 comprising 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 a perspective view according to an embodiment. The constructional system 5 may comprise a framework 1 and a plurality of such coupling elements 3, wherein only one coupling element 3 is depicted in fig. 1 for the sake of simplicity. The framework 1 and coupling elements 3 are configured to be coupled to each other so as to provide a structural arrangement. The framework 1 may comprise a plurality of individual frames, coupled to each other in a fixed manner. The plurality of frames may be comprised of a circumferential front frame 7, two side frames 9, arranged at opposite sides of said front frame 7 and extending perpendicular away therefrom, a top frame 11 and a bottom frame 13, arranged at a top side and a lower side of the front frame 7 respectively, and extending perpendicularly away therefrom, in the same direction as the side frames 9. The different individual frames 7, 9, 11, 13 may, as depicted in fig. 1, have specific designs to provide different types of functions and allow of access to different areas of the framework 1. The framework 1 and the frames 7, 9, 11, 13 thereof may be manufactured in various materials, however metal is most likely preferred to allow for large loads and forces to be subjected to the framework 1 when assembled. The

circumferential front frame 7 is herein depicted as solely circumferential around an encircled open area therein, wherein corners of the front frame are rounded in their design. The rounded corners may allow for a better distribution of forces within the construction without unnecessary 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 to provide sharp corners. The front frame 7 may also have additional frame elements added thereto, which additional elements may, for example, extend horizontally over the open area of the frame 7, without deviating from the scope of protection. The side frames 9 may comprise a sideways directed U-shape, further provided with an additional angled structural element 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 increased strength and stability to the completed framework 1. The top frame 11 and the bottom frame 13 may as depicted herein be similar in shape and design, and both may comprise a circumferential portion 21 and an inner structural network portion 23 each. The framework 1 may further comprise at least four coupling beams 25, extending in parallel with the side frames 9, the top frame 11 and the bottom frame 13, herein extending from edges defined by interconnections of said frames 9, 11, 13, said coupling beams 25 may further comprise an outer circumference having a certain shape and design. The relative sizes of the coupling beams 25 and the top and bottom frames 11, 13 are, as depicted in fig. 1, designed to define an open upper area and an open lower area within the framework 1. The functionality of these two open areas will be explained in more detail later in the disclosure. The coupling element 3 may comprise an anchoring portion 27, configured to be attached to or in a constructional 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 29 may comprise an inner circumference that is arranged to be form fitted with the outer circumference of the coupling beams 25 of the framework 1. The coupling elements 3 may be provided with a predetermined set inner length 31, which inner length 31 provides a set distance the coupling beams 25 may be inserted into such a channel 29. The previously mentioned open areas of the top and bottom frames 11, 13 may thus be defined and determined by means of sizes of the top and bottom frames 11, 13, the inner length 31 of the inner channel 29 of the coupling elements 3 and the coupling beams 25, wherein the open areas will correlate to the area there in between. The anchoring portion 27 may be designed differently depending on what type of building or structure they are intended to be positioned within. Known and conventional techniques within the art may be used to arrange and fix said anchoring portions 27 reliably within a fagade of a building. It should be mentioned however that the coupling elements 3 may be incorporated into other structural elements of a building at a prior point in time, if it is known the constructional system according to the disclosure is to be used at said building. There are also certain building systems that may be even more suited for having such coupling elements 3 incorporated therein, wherein the coupling elements 3 according to this disclose may in part be parts of certain structural elements of other constructional modular systems. As an example, certain types of prefabrication building systems may have horizontal elements in which the coupling elements 3 according to this disclosure herein may be coupled to as part of said prefabrication system, wherein the coupling elements 3 will be a part of the 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 fagade of a building by means of attaching a plurality of coupling elements 3 to said building, wherein the anchoring portions 27 are fixedly attached to the building so that the at least one inner channel 29 is reachable from said fagade. Wherein at least one framework 1 is coupled to the coupling elements 3 by means of the coupling beams 25 so that the at least one framework 1 extends out from said fagade and constitutes the structural arrangement thereto.

Fig. 1 only depicts one coupling element 3, wherein it should be obvious that additional coupling elements are to be perceived to be positioned in empty corners of a polygonal unit 33, which is depicted in dashed lines in fig. 1. The shape of a predetermined pattern in which the 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 anchoring portions 27 thereof will, when used in combination, provide a rigid and reliable structural arrangements that may extend out from facades of buildings. Such structural arrangements may be subjected to large loads and forces, which loads and forces are distributed over the building and its fagade in an efficient manner.

The constructional system 5 may be used to provide a structural arrangement, which may be temporary attached to a building, so as to provide a temporary construction scaffolding thereto. Thereby a scaffolding may be attached to a building without the need for support of said scaffolding at ground level adjacent said building. The structural arrangement provided by means 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 and similar, but the basis for providing the mechanical integrity of the 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 a permanent balcony framework thereto. Similarly to when using the system 5 to provide a scaffolding, the structure may need to be complemented with additional elements before a fully functional balcony is achieved, but the structural framework providing the mechanical integrity is provided by means of the attached framework 1 of the constructional system 5.

For 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 attachment between the framework 1 and the coupling elements 3, when the system 5 is used to provide a scaffolding. For a balcony construction, screws or other such fastening elements may also be used, but options such as welding or other types of more rigid attaching method may also be used, 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 a balcony to a building, by means of using the same framework 1 for both said purposes at different points in time. A plurality of frameworks 1 may be temporary attached to a building to provide a scaffolding, either as part of the construction of said building, or at a later point in time for a refurbishing of said building. When the constructional work utilizing such a scaffolding is completed, the frameworks 1 in positions for use of balconies may then be kept in place and those not desired to keep may be removed and used at another subsequent building and/or construction site. The frameworks 1 remaining on the building may be complemented 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 different embodiments. In short fig. 2a shows a single-channel 29 coupling element 3, fig. 2b shows a multiple-channel 29 coupling element 3, and fig. 2c shows a coupling element 3 provided with an internal electrical socket 33. It should also be mentioned that the coupling elements 3 are to be perceived as schematic in their depiction, wherein specifics regarding their design such as 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 a single inner channel 29, arranged to house a single corresponding coupling beam 25 of a framework 1. The inner channel 29 may comprise an inner circumference, designed to fit with an outer circumference of a coupling beam 25 of a framework 1 of the constructional system 5. The inner channel 29 may further comprise a predetermined inner length 31, which length 31 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 always known how far out from the building the framework 1 of the system 5 will extend, as long as an outer edge 35 of the coupling elements 3 is arranged within the fagade of the building in a controlled manner. The coupling element 3 may further comprise an anchoring portion 27, which extends away from the inner channel 29 in a direction opposite of said inner channel 29. The anchoring portion 27 is arranged to be inserted in a wall or other similar rigid part of a building, so as to be firmly and reliably positioned within a fagade of said building. Depending on the type of building, or the type of method a building is raised with, the anchoring portion 27 may be modified to conform in the best possible manner with the structural components of said building. It is also possible to further modify the possible ways to arrange the anchoring portion 27 of a coupling element 3 by means of adding additional adapter elements, arranged to fit with a certain design of the anchoring portion 27, and also fit with a certain type of material, design or element of a specific building and/or building type. The anchoring portion 27 may also be increased in length by a large margin (compared to schematic representation depicted in fig. 2a) if it is more suitable for a specific constructional solution related to a specific building. The anchoring portion 27 is to be the part of the coupling element 3 that provides a reliable attachment to a building, however a circumferential wall 37 enclosing the inner 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 29 coupling element 3 as depicted therein comprises a total of four inner channels 29, arranged in a quadrant each within the space encircled by the circumferential wall 37 of the coupling element 3. Each such inner channel 29 may thus be used to receive and hold one coupling beam 25 of a framework 1 each. This may be utilized to arrange a plurality of frameworks 1 adjacent each other in a reliable and precisely repeatable manner. Other than the difference between the coupling element 3 as depicted in fig. 2a, having one inner channel 29, and the coupling elements 3 as depicted in fig. 2b, having four inner channels 29, the two depicted coupling elements 3 may be perceived as similar to each other, wherein the description of the coupling element according to fig. 2a may be thought of as describing the coupling element 3 according to fig. 2b as well, with regards to other parts of the two respective coupling elements 3. As also previously stated, fig. 2c shows a coupling element 3 provided with an internal electrical socket 33. Also shown in fig. 2c is part of a corresponding coupling beam 25. The constructional system 5 may comprise a plurality of coupling elements 3, wherein at least one coupling element 3 and the framework 1 further comprises an electrical socket 33 and plug 39 respectively. Coupling of said socket 33 and plug 39 may be achieved automatically when the two structural elements 3, 25 are coupled to each other, which is provided by means of the geometries of said components and how they are arranged to fit in only one orientation relative each other. The framework 1 may further comprise an electric cable 41 arranged therein, which cable 41 is connected to a framework socket (not shown in fig. 2c), arranged at a predetermined position of the framework 1. The coupling element 3 as depicted in fig. 2c comprises, 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 four coupling beams 25, each framework 1 may thus be provided with electricity from solely one of said four coupling beams 25. However, it is of course possible to arrange internal electrical sockets 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 system 5.

All of the different embodiments of the coupling elements as depicted in figs. 2a-c are to be perceived as manufactured in a robust and strong material, which may be a metallic material such as a hardened steel, a stainless steel or a strong metallic alloy, a ceramic material, a composite 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 3 arranged in a fagade 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 is clearly seen that the top frame 11 of the framework 1 is situated at a distance 45 from the fagade of the building 43. The open area there between provides the option of arranging flights 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 a variety of structural arrangements to the building 43. If used as a temporary construction scaffolding, stairs between different floors are of course needed to be able to provide movability between different floor levels within said scaffolding. If the framework 1 instead is to be used as a permanent structural arrangement, such as a balcony, additional floor elements and/or roof elements may easily be arranged to cover the open area. The framework 1 may also be part of other types of permanent attached structures, such as an exteriorly positioned corridor or similar, which may be function as a substitute for internally positioned stairwells, fire exit stairs or similar in a building with a plurality of floors. For such cases the open 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 frameworks 1.

In a similar manner the side view of the framework 1, as depicted in fig. 3b, clearly shows that the side frame 9 provides an open space therein as well. When the framework 1 is arranged to the building 43 to be part of a temporary scaffolding, said open space provides an easy access to horizontal movability between correspondingly horizontally adjacently arranged

frameworks 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 arranged thereto by means of using the constructional system 5 according to an embodiment. The building 43 as depicted is not fully completed, but is to be perceived as a building 43 under construction, wherein a total of nine room units are arranged in three floors of said building 43. As is seen in the depiction, the frameworks 1 have been provided with temporary scaffolding 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 elements 49 are provided to each structural arrangement at the fagade to provide an easier to use and stable walking area for construction workers working on the building 43. Stair units 51 have been provided to two structural arrangements so as to provide vertical movability within the scaffolding 47. One of the inner channels (inner channels and features comprised therein are not seen in fig. 4 however) of a coupling element 3, and its corresponding framework 1 coupled 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 comprises an electric cable 41 arranged therein, which cable 41 is connected to a framework socket 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 1 of the depicted system 5, or to a selected plurality of frameworks 1 as well. Furthermore, the framework socket 53 may also be moved to other parts of the framework 1 if deemed more suitable for specific application of the constructional system 5.

The coupling elements 3 according to fig. 4 is to be perceived as being similar to the embodiments of the coupling elements 3 as depicted in figs. 2b and 2c, all comprising four inner channels 29 therein. It may also be seen in fig. 4 how the coupling elements 3 are arranged relative the building 43 and its fagade. The fagade of this building 43 is provided with a plurality of fagade elements 55, which are arranged to the room units of the building 43. The coupling elements 3 may then be arranged so as to sit flush with an outer surface of said fagade elements 55 so as to provide a correct alignment between the building 43 when the fagade is completed, the coupling elements 3 and the frameworks 1 of the constructional system 5. Additional fasteners and/or fastening methods may also be used to securely attach the coupling elements 3 to the building 43 before the fagade elements 55 are put in place. Thereby such fasteners and fastening methods may be hidden from view when the building 43 is fully assembled.

Furthermore, it may herein also be seen that the coupling elements 3 may be attached to structural elements 57 of the building system used to raise the building 43 in question. The building 43 herein is to be perceived as being assembled by means of a specific prefabrication building system, which system comprises a specially designed structural element 57 that is arranged between the room units of said system. By means of incorporating the coupling elements 3 into such structural elements 57 prior to assembly of the building 43 is initiated, the two systems, namely the prefabrication building system and the constructional system 5 according 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 building 43.

The construction scaffolding depicted in fig. 4 may thus be described as comprising a plurality of 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 the disclosure. The frameworks 1 of the scaffolding 47 and thus also the constructional system 5 by which they are provided, may further be configured to be left remaining on said fagade so as to constitute a permanent structural framework of a balcony to said building 43. Thus, any one of the frameworks 1 as depicted in fig. 4 may be opted to be left attached to the building 43 as shown. Correspondingly, any framework 1 not to be used as part of another type of structural arrangement may also be removed from the building 43, as commonly performed for a prior art scaffolding solution. The frameworks 1 decided upon to be kept however may simply to be complemented with predetermined additional balcony components so as to complete a balcony assembly for each and every one of the position where such is desired, and to achieve a specific balcony 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 the assembly. The stairs 51 may or may not be removed, depending on the type of balcony and/or the type of building that is to be assembled. If the different floors of the building 43 are to constitute separated floors with individual balconies thereto, the stairs 51 would be most suitable to remove. But if the balconies as to constitute parts of exteriorly positioned corridors or 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.

Fig. 5 shows a flowchart of a method for arranging a constructional scaffolding to a fagade of a building according to an embodiment. The method shown by means of the flowchart is to be perceived as using a constructional system according to disclosure, wherein the method may comprise the steps of: a) arranging a plurality of coupling elements in a predetermined pattern at a fagade of a building, b) inserting at least one framework into the arranged coupling elements, and c) arranging temporary scaffolding components to the at least one framework. Step a) may be performed in advance and/or in combination with parts of assembly of said building. Thus, step a) is to be perceived as being performed in a plurality of ways, such as arranging all coupling elements to an already existing fagade, or arranging the coupling elements bit by bit as the construction/assembly of the fagade is being performed to name a few examples. The coupling elements may also be arranged in or at specific constructional elements that are to line up with the fagade in a proper manner, wherein assembly of the building and/or fagade thereof positions the coupling elements 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 a specific floor of a building, wherein the steps a), b) and c) are performed in that order for one current floor being assembled/built, wherein the steps then are repeated for the next floor of the building, and so on until all floors of the building are assembled. The temporary scaffolding components as mentioned with reference to step c) may be components such as floor elements, wall elements, roof elements, stairs and steps, additional safety rails, or other similar 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 fagade of a building provided with a construction scaffolding according to an embodiment. Thus, the method shown in the flowchart of fig. 6 is to be perceived to be used on a building already provided with a construction scaffolding by means of the constructional system according to the disclosure. The starting point for the method shown in fig. 6 is thus the end result of the method as shown in fig. 5, wherein further construction of a balcony to said fagade of the building is to be performed. The method may comprises the steps of: d) removing the temporary scaffolding components from the at least one framework, and e) arranging additional structural elements to the framework so as to provide a balcony. Step d) may of course not necessary mean the removal of all components, if some specific

component/components are usable for the construction of the balcony, they may of course be left remaining on the structural arrangement. Furthermore, the term balcony is herein to be interpreted in a broad sense, and may be mean a single balcony, a larger set of several balconies, or a similar structure arranged at a fagade of a building, such as an exteriorly positioned corridor and/or stairwell or similar.
