Definitions

• the present invention refers to a method to build vertical wall portions, in which plate shaped construction elements are used and mounted on both sides of a support erected in advance.
• the support is erected of vertical shores mounted between a bottom and a top profile.
• the shores and the other profiles are preferably made of sheet metal.
• the support is then provided with horizontal elements, for instance in the shape of rods mounted at predetermined levels.
• the bars can be constituted by reinforcing bars.
• construction elements are utilized which are provided with mounting elements that can be hook- shaped and extend outwards from one of the lateral surfaces and be located and designed such that they can be hooked on and fixed to the horizontal elements of the support.
• the invention also refers to a mounting element for use in the method.
• the sheet metal shores contained in the wall structure serves both as reinforcement in itself, as well as a support of the present reinforcement and also as a support of the remaining wall plates - the finished wall surface.
• the bottom and top profiles of the sheet metal shores also serves as a fixation of the standing reinforcement in the wall structure. Even oiling of moulds and removal of them is eliminated with this method where the mould is remaining and forms a finished wall surface.
• the construction elements can already at the assembly consist of or be provided with an external facing layer or a surface material for interior walls.
• the shores are provided with holes to enable supply and faciliate the distribution of the concrete. It is also possible to utilize construction elements containing plate shaped insulation material or extra cavities for insulation when the construction elements according to the invention are used in concrete moulded walls.
• Figure 1 shows a wall portion assembled according to an embodiment of the invention.
• Figure 2 shows an example of the structural design of a construction element with hook shaped mounting elements according to the invention.
• Figure 3 shows an example of a hook shaped mounting element intended to be utilized in connection with the invention.
• FIGS 4 - 7 show a second embodiment of profiles of a wall portion according to the invention, whereby Figure 4A shows a shore from one side, Figure 4B this shore in profile and Figure 4C an enlarged portion C of the shore.
• Figure 5A in a corresponding way shows a portion of a bottom or a top profile from one side, while Figure 5B shows this profile in a profile and Figure 5C shows the bottom or the top profile in perspective.
• Figure 7A shows a corner of a shore support and a bottom profile from the side and Figure 7B shows a view from the above according to section B-B in Figure 7A.
• a plate shaped construction element 10 is provided with mounting elements 20, which are hook shaped and extend outwards from one of the lateral surfaces of the construction element.
• the mounting elements are located and designed such that they can be hooked on and fixed to the horizontal bars 6 of the support.
• Each mounting element consequently has a spacing portion which after anchorage in the plate shaped construction element may extend essentially perpendicular outwards from the lateral surface with a predetermined length, and a retainer portion that extends essentially perpendicular from the spacing portion at its external end so that a hook is formed.
• the plate shaped construction elements 10 may be moulded of concrete and reinforced.
• Figure 2 only diagrammatically shows how they can be built. The thickness may be down at one or some centimeters.
• FIG. 3 A particularly advantageous embodiment of the mounting element according to the invention is evident from Figure 3.
• the spacing portion 23 in this embodiment is provided with a hinge 25, which at mounted mounting element is placed at the plate surface.
• the hinge 25 is designed such that the mounting elements at transport and storage can be folded to the side, while the essentially perpendicular folded out still can support the construction elements at an intended level.
• other variants of mounting elements also can be used. These can for instance be made of flat iron or of sheet metal profiles and also the anchorage in the construction elements may be different.
• FIG. 4 A - C thus shows a shore which similarly to the bottom and the top profile according to Figure 5A - C are constructed as a U-beam with a web 31 and 41 respectively and two shanks 32 and 42 respectively and 33 and 43 respectively. From the end of each shank further a portion extends outwards, 34 and 44 respectively and 35 and 45 respectively, and these are ended by bent backwards flanges 36 and 46 respectively 37 and 47 respectively. All angles are essentially right.
• the shore 30 according to Figure 4 A-C as in the first embodiment is broken through by large holes, through which concrete may flow, and by smaller holes 38 for bars or reinforcing iron with an exactly defined location.
• recesses 39 adapted to let reinforcing iron of different dimensions to be able to be placed and remain in its location against the shank 32 or 33 with a space between the reinforcement and the flange 36 and 37 respectively.
• the bottom and top profiles according to the Figures 5 A - C are designed as the shores according to the Figures 4 A - C but are provided with holes 48, in which vertical reinforcing iron can be mounted, and angled recesses 49 in which vertical shores can be mounted.
• a double stay 52 with conical angled out ends can be provided to fit in into holes 53 and 54 arranged for this to hold the shores at right angle.
