Field of the inventionThe invention relates to a prefabricated collapsible reinforcing skeletal framework, for the construction of reinforced concrete structures, as disclosed in independent claim 1.Background of the inventionReinforced concrete is widely used in many different types of structures and components of structures such as slabs, walls, floors, foundations, beams and for civil engineering projects such as for bridges, dams and so on. Most reinforced concrete structures comprises a reinforcing skeletal frameworks usually a steel framework.Reinforcing steel bars where traditionally assembled into a framework on the building structure and then concrete is poured around the framework to form a floor or wall, for example. Constructing the reinforcing framework on site is relatively time consuming and generally skilled steel workers are required. Lately it has become more common to prefabricate the reinforcing framework in modules off site in a factory or similar facility, and then transport the reinforcing framework to the building site in modules.In a floor slab, the reinforcing framework typically comprises two layers comprising rebar arranged and fixed in a mesh pattern. The mesh layers are usually arranged with a distance between them of typically 100 – 500 mm depending on the thickness of the floor. A prefabricated reinforcing skeletal framework for such a floor slab will then have quite a large volume which is a drawback when it comes to transportation. A truck or trailer will be filled up without coming close to the weight limitation of the truck or trailer.Transporting such prefabricated reinforcing framework modules is therefore quite costly and the carbon footprint increases drastically as a result of the transport. EP80236 A2 discloses a metal frame for building structures made of reinforced concrete, comprising longitudinal rods and transversal rods reciprocally joined by articulated joints, for the volumetric extension of such frame.FR3012157 A1 relates to a passive reinforcement assembly for a building material, which comprises reinforcement bars and a reinforcement element extending transversely to the bars and comprising a cable which extends in contact with the bars.Object of the inventionAn object of the invention is to provide a prefabricated reinforcing skeletal framework that takes up less room during transport compared to prior art solutions.Another object of the invention is to provide a prefabricated collapsible reinforcing skeletal framework.Yet another object of the invention is to provide a easy to use solution for prefabricating, transporting and using prefabricated skeletal frameworks.Yet another object of the invention is to provide a prefabricated reinforcing skeletal framework where only the rebars necessary for the structural integrity of the reinforced concrete is of structural grad quality, in the rest of the prefabricated skeletal framework it can be used scrap metal, cut off/leftovers of rebars or lower quality metal.Summary of the inventionIn one aspect the invention relates to a prefabricated collapsible reinforcing skeletal framework, for the construction of reinforced concrete structures. The skeletal framework comprises:- at least two mesh layers, namely a first mesh layer and a second mesh layer, and- at least two spaced apart spacers connecting said two layers. Each spacer is pivotally connected to the first mesh layer in a first connection point and each spacer is pivotally connected to the second mesh layer in a second connection point. Each spacer is pivotable around substantially parallel axes passing through the first and the second connection points, wherein each of the mesh layers comprises rebars arranged in a pattern with parallel spaced apart Y-directional rebars and parallel spaced apart X-directional rebars, wherein the Y-directional rebars is arranged substantially transversal to the X-directional rebars, wherein each spacer comprises at least one spacer bar having in each end a section of pipe being perpendicular to the spacer bar, and the two sections of pipe is arranged in parallel to each other, and wherein each of the pipes accommodates an X-directional rebar. The spacer comprises a pivotal joint in between the first and the second connection point, so that the spacer can be manipulated from a folded configuration to an unfolded configuration and wherein the spacer comprises a snap mechanism so that the spacer locks in the unfolded configuration when moved from the folded configuration.The resulting technical effect of the two mesh layers being connected by spacers as disclosed above is that the reinforcing skeletal framework is collapsible. Hence, the skeletal framework can be collapsed so that there is no or a verry little space between the first and the second mesh layer. If the first mesh layer is resting on a horizontal surface the second mesh layer can be moved between a first position wherein the second mesh layer rests on top of the first mesh layer and a second position wherein the second mesh layer is at a distance from the first mesh layer. Said distance equals the length of the spacers. The two mesh layers can of course also be arranged in any position in between the first and the second position.The advantage of having a collapsible prefabricated skeletal framework is that it saves space during transportation. When the skeletal framework is used as reinforcement in a concrete floor slab the two mesh layers will typically be arranged as two parallel layers with a distance between them of between 100 mm and 500mm. Collapsible skeletal framework, will compare to stacking skeletal framework with such thickness on top of each other on a trailer, makes room for many more skeletal frameworks on one trailer load.The skeletal framework can be a skeletal steel framework.The mesh layers can comprise rebars and the rebars can be connected in a mesh by tying the rebars together in the intersections using tying wire. Other methods known to the skilled person can also be used and the method of securing the rebars to each other is not essential to the invention.The mesh layers can be layers of y-directional rebars held in place by relatively fewer x-directional rebars (transverse to the Y-directional rebars).The purpose of the spacers is to maintain the position of the mesh layers relative to each other until the concrete has cured. The spacers are not intended to contribute to the structural integrity of the cured concrete. Hence, the spacer does not need to have the same material quality and strength as the rest of the skeletal framework.The two mesh layers can be movable relative to each other between a first collapsed position wherein the first mesh layer is in contact with the second mesh layer and a second erected position where the second mesh layer is at a distance from the first mesh layer.The at least two spacers can be substantially perpendicular to both mesh layers in the second position and wherein the first mesh layer and the second mesh layer can be arranged in substantially parallel planes in the second position.When the prefabricated skeletal framework is used as reinforcement in a concrete floor slab, it is desirable that the two mesh layers are arranged in parallel planes. For the construction of other types of reinforced concrete structures, it might be need for two or more mesh layers arranged in non-parallel planes. If the mesh layers are not to be parallel, then the spacers can have different length to achieve this. Rebar is short for reinforcing bar.A rebar passing through a pipe act as a pivoting joint (a hinge) between a mesh layer and a spacer.The length of the pipe accommodating a X-directional rebar is preferably equal to or less than the space between each of the spaced apart Y-directional rebars. Thus, the spacer being prevented from sliding along the X-directional rebar and at the same time not being jammed between the X-directional rebar and transverse Y-directional rebars of each layer.It should be understood that the terms Y-directional and X-directional is only used for the purpose of distinguishing between / defining two different directions in which rebars are arranged. This is only to make it easier for the reader to understand. The skilled person will understand that it just as well could have been written that the pipes of the spacer could be arranged onto a Y-directional rebar.The transverse bars can be welded to the spacer bars.The eyes can be formed by bending the ends of the spacer bars.The two eyes, in an end of the spacer arranged to connect to the first mesh layer, can be arranged on a opposite side of the spacer bars compare to the two eyes arranged to connect to the second mesh layer, and the x-directional rebars arranged to be accommodated inside the eyes can be on both mesh layers arranged on the inside of the skeletal framework relative to the y-directional rebars.This has the effect that when the skeletal framework in its collapsed position/configuration it can have a thickness equal to the thickness of only three rebars. In the above disclosed embodiment, the spacer has a pivotal joint. This pivotal joint can for instance be at the middle of the spacer half way between the connection point to the first and the second mesh layer. The pivotal joint should be arranged so that it pivots around an axis being parallel with the axis through the connection point to the first and the second mesh layer. When having this additional pivotal joint, the spacer can be folded when the skeletal framework is in its collapsed position and when moved to the erected position the spacer is unfolded and secured in the unfolded position by the snap mechanism. The snap mechanism can be releasable so that the spacer can be folded again.The skeletal framework can further comprise bracing arranged for securing the two mesh layers in the second erected position.The purpose of the bracing is to maintain the position of the mesh layers relative to each other until the concrete has cured. The bracing is not intended to contribute to the structural integrity of the cured concrete. Hence, the bracing (and the spacers) do not need to have the same material quality and strength as the rest of the skeletal framework.The bracing can comprise at least one removable rigid strut arranged between an X-directional rebar in the first mesh layer and an X-directional rebar in the second mesh layer. Said rebar of the first and the second mesh layer can be displaced in relation to each other in the axial direction of the Y-directional rebars when the skeletal framework is in its second erected position.The bracing can comprise at least two rigid struts, namely a first rigid strut and a second rigid strut. Each having an eye in one end. The eye of the first rigid strut can accommodate a x-directional rebar of the first mesh layer, while the eye of the second rigid strut can accommodate a x-directional rebar of the second mesh layer. The two eyes can be displaced in relation to each other in the axial direction of the Y-directional rebars when the skeletal framework is in its second erected position. The two rigid struts can be secured to each other by letting them overlap a distance and fixing them to each other using at least one clamp.The clamp can be a wire clamp or Bulldog/U-Bolt clamp.Description of the figuresFig. 1 shows a section of a prefabricated collapsible reinforcing skeletal framework in a perspective view. The skeletal framework is erected and bracing is in place to secure the skeletal framework in its erected position/configuration.Fig. 2 shows the same skeletal framework as in Fig.1 but from a different angle and from further away.Fig. 3 shows a part of a skeletal framework where a spacer is arranged for holding a distance between two mesh layers in the skeletal framework.Fig. 4. Shows the same part of a skeletal framework as in Fig.3, but from a different angle.Fig. 5 shows an embodiment of a spacer alone in a close up view.Fig. 6 shows another embodiment of a spacer alone in a close up view.Fig. 7 shows a part of a prefabricated collapsible reinforcing skeletal framework in a perspective view. In Fig.7 the skeletal framework is in its collapsed configuration/position and one can see a spacer centrally in the figure. The spacer seen in Fig.7 is a different embodiment of the spacer compared to in the previous figures.Fig. 8 shows a section of the same skeletal framework as seen in Fig.7. In Fig. 8 the skeletal framework is in its erected configuration/position.Fig. 9 shows a spacer in a close up view. This spacer is the same embodiment as the one seen in Fig.7 and Fig.8. Fig. 10 shows an embodiment of the bracing for fixing the skeletal framework in its erected configuration/position. Most of the mesh layer is removed from the figure, but that is only to get a better view of the bracing and its connection to the transversal rebars (x-directional rebars). In Fig.10 the bracing is not yet secured with clamps as the one seen in Fig.11.Fig. 11 shows an embodiment of a clamp that can be used for securing the bracing. This embodiment is a clamp similar to a standard wire clamp.Fig. 12 shows a prefabricated collapsible reinforcing skeletal framework in it collapsed configuration/position.Fig. 13 shows the prefabricated collapsible reinforcing skeletal framework of Fig.12 in a configuration/position in between collapsed and fully erected.Fig. 14 Shows the prefabricated collapsible reinforcing skeletal framework of Fig.12 and Fig.13 now in its fully erected configuration/position.Description of preferred embodiments of the inventionIn the following embodiments of the prefabricated collapsible reinforcing skeletal framework 10 will be described with reference to the figures.As seen in Fig.1 and Fig.2 the skeletal framework 10 comprises a first 11 and a second mesh layer 12 that is connected by spacers 13. The spacers 13 are pivotally connected to both mesh layers 11,12 in the connection points 21, 22 so that all the spacers 13 can pivot in the same direction, i.e. they can all pivot around parallel axes. The effect of this is that that the two mesh layers 11, 12 can move relative to each other between a collapsed position/configuration and a erected position.The number of spacers 13 needed is dependent on the size and the stiffness of the mesh layers 11, 12.The mesh layers 11, 12 comprises rebars 15 arranged in a mesh pattern. To be able to distinguish between the two direction which the rebars 15 is arranged in we refer to them as X-directional rebars 15X and Y-directional rebars 15Y. In the embodiments in the figure there are relatively fewer rebars 15 in what we have defined as the X-direction.In Fig.1 and Fig.2 the skeletal framework 10 is in its erected position which is the position/configuration it is intended to be arranged in when cast inside a concrete floor, for instance. The skeletal framework 10 is secured in its erected position by bracing 14.Fig. 3 and Fig.4 is centred on an embodiment of a spacer 13 arranged in the skeletal framework 10. The spacer 13 comprises in this embodiment (also see Fig. 5) two parallel spacer bars 13.1 and two pipes 13.2 one in each end of the spacer bars 13.1. The pipes 13.2 is arranged in parallel perpendicular to the spacer bar 13.1. Each pipe 13.2 accommodates an X-directional rebar 15X, and this makes up the pivotal connection or hinge connection between the spacer 13 and the mesh layers 11, 12.Fig. 5 shows a spacer 13 alone. The spacer 13 being the same embodiment as the one seen in Fig.3 and Fig 4. Fig. 6 shows an embodiment of the spacer 13 which has only one spacer bar 13.1, but apart from that, the spacer 13 of Fig.6 is similar to the spacer from fig.5.Fig. 7 and Fig.8 shows another embodiment of the spacer 13 arranged in a skeletal framework 10. In Fig.7 the skeletal framework 10 is in its collapsed position and in Fig. 8 the skeletal framework 10 is in its erected position. This embodiment of the spacer can be made exclusively from scrape metal/rebar leftovers and comprises two spacer bars 13.1 each being bent in both ends to form an eye 13.4 in each end and two transvers bars 13.3 to connect the spacer bars 13.1 to each other. The eyes 13.4 is accommodating a X-directional rebar 15X and this makes up the pivotal connection /hinge connection between the mesh layers 11, 12 and the spacers 13.Fig. 9 shows the same embodiment of the spacer 13 as the one seen in Fig. 7 and Fig. 8.Fig. 10 shows and embodiment of the bracing 14. The Y-directional rebars 15Y is removed to be able to show the bracing 14 more clearly, in reality there would be Y-directional rebars 15Y in place. The bracing 14 comprises four rigid struts 14.1 each having an eye in one end and the eye is accommodating a X-directional rebar 15X. When the skeletal framework 10 is in the collapsed position the rigid struts 14.1 can be arranged laying parallel to the mesh layers 11, 12 and when the skeletal framework 10 is erected and is to be secured in the erected position the struts 14.1 is arranged diagonally between the mesh layers as bracing 14. The struts 14.1 is long enough to overlap a meeting strut 14.1 diagonally and two and two overlapping struts 14.1 can be secured to each other using clamps 14.2 as the one seen in Fig 11.Fig. 12 shows a skeletal framework 10 in its collapsed position. In Fig.13 the same skeletal framework 10 is moved to a position in between collapsed and fully erected and in Fig.14 the skeletal framework 10 is fully erected and bracing 14 is in place.
