Definitions

  • the invention relates to a component for the production of building walls made of concrete, which allows the building of building walls, be it in in-situ concrete or in prefabricated construction also without formwork. It is a particular object of the invention to incorporate the required insulation as an integral part of the building wall during manufacture.
  • the object of the invention is achieved by a component which is characterized by a frame made of a sheet metal profile that runs around the edge, at least one strut made of a sheet metal profile connecting two frame sides, a metal grid attached to at least one outer plane defined by the frame, and flatly covering the frame, and at least one rod-shaped assembly iron, each running a short distance from the metal grid within the frame and two opposite one another Frame sides and the strut connects and connecting elements that connect the metal grille and the assembly iron.
  • a wall element can be assembled in a simple manner from prefabricated individual parts on a building yard or, for larger construction projects, also on the building site. By using sheet metal profiles, the fully assembled component can be easily handled with the lifting devices that are customary at the construction site.
  • the height of a component corresponds to the desired floor height, while the length when concreting on site can correspond to the entire length of the building.
  • the number of struts used depends on the length of the component. These can be provided, for example, so that they laterally limit the desired door and / or window openings at the same time.
  • a metal grid is attached to at least one outer plane defined by the frame, which in a preferred embodiment of the invention is formed by sheets of expanded metal.
  • the expanded metal sheets expediently have openings of approximately 5 mm in width and approximately 10 to 20 mm in length.
  • the expanded metal sheets are fastened to the frame in a perpendicular manner with respect to the orientation of the building wall.
  • the metal grill can be attached to the frame by spot welding or with the help of self-tapping screws.
  • this is fixed at appropriate intervals on the mounting irons running transversely to the orientation of the expanded metal tracks with the aid of connecting elements, for example wire hooks or the like.
  • the shotcrete layer lying on the outside of the wall on the metal grid is thinner than the shotcrete layer lying on the inside, which is so thick that it also completely embeds the assembly iron.
  • the insulating material is now applied to the concrete layer from the inside, for example in the form of a foamed plastic, in particular polyurethane.
  • the frame area in the corresponding areas is now covered with a metal grid on the still open frame level, which now forms the inside wall of the building, this being connected to the frame, the struts and the assembly iron.
  • Sprayed concrete is then applied to the outside of this metal grid in the desired thickness, this sprayed concrete layer building up directly on the insulating material layer and being chosen so thick that the outside of the metal grid is again completely covered with concrete.
  • At least the horizontally extending sheet metal profiles of the frame have a U-shaped cross section. This has the advantage that the sheet profile is enclosed without the formation of voids when the shotcrete is introduced.
  • the sheet metal profile forming the struts and expediently also the vertically running profile parts of the frame have a C-shaped cross section. This results in additional stiffening of both the component and the building wall erected with the aid of this component, since the stiffness of a C-shaped sheet metal profile is considerably higher.
  • the sheet metal profiles are expediently produced by folding or rolling from a galvanized steel sheet with a thickness of approximately 1.25 mm. When using expanded metal, a sheet thickness of 0.8 mm is considered appropriate here on the one hand for reasons of strength and with regard to the weight of the component. A round iron with an 8 mm diameter is sufficient for the assembly irons.
  • the webs have openings at least in the vertically running sheet metal profiles of the frame and the struts.
  • the component according to the invention can be used not only for the erection of building walls but also of floor ceilings.
  • those are related to the frame Struts formed by sheet metal profiles with an I cross section.
  • the metal grid is applied only on the underside and is embedded in a shotcrete layer of appropriate thickness in the manner described above.
  • the other side of the shotcrete layer is covered as described above with an insulating material layer, for example made of foamed plastic.
  • the frame is covered on one side only with a metal grid and that on the other side of the surface on the flanges of the I-shaped struts open U-profiles are made of sheet metal for supporting beams.
  • the support beams can be made of reinforced concrete or wood, but are firmly connected to the U-profile of the struts in the ceiling.
  • This arrangement has the advantage that the load on the surface load acting on the ceiling is largely carried out via the supporting beams, while the actual floor ceiling is designed in the manner of a suspended ceiling and, accordingly, considerable weight reductions are achieved.
  • a building wall produced with a component according to the invention is characterized in that at least one of the metal grids covering the frame is embedded in a load-bearing layer made of shotcrete and that the space between the two concrete layers is filled with insulating material.
  • the insulating material consists of a foamed plastic, preferably polyurethane, in a manner known per se. This has the advantage that the insulating material layer can also be introduced in corner areas which are difficult to access. All exposed metal surfaces are thereby completely and tightly covered, so that extensive corrosion protection is achieved.
  • a component is shown in a schematic view.
  • the component has a circumferential frame 1, which is dimensioned so that its height h corresponds to the floor height, while its length 1 corresponds, for example, to the desired length of the building or a "room length".
  • the frame 1 is divided in the longitudinal direction by a plurality of struts 2, the struts 2 'each running diagonally in the end region and providing a corresponding corner stiffener.
  • the struts 2 are arranged at a distance from one another in such a way that they simultaneously delimit a door opening 3 and window openings 4 laterally.
  • the upper and / or lower limit of the door or window opening is limited by horizontally extending interchangeable struts 3 'and 4', 4 ", each with the opening-defining struts 2 are firmly connected.
  • a metal grid for example made of expanded metal sheets.
  • these grid areas are not shown here.
  • the fields of the frame 1 to be covered by the metal grid are additionally divided by horizontally running mounting irons 5, for example made of 8 mm round steel, to which the metal grid is still connected by connecting elements in the form of wire hooks or the like. This will be explained in more detail below.
  • the construction elements according to FIG. 1 which are covered on a surface with metal grids, are set up and aligned on a prepared foundation 6.
  • the frame parts delimiting the component at the top and bottom are formed from a U-shaped sheet metal profile 7.
  • the mounting iron 5 are inserted through corresponding holes in the struts 2.
  • One of the struts is indicated here.
  • a metal grid 8 is fastened to the outside of the frame 1, for example by spot welding or with the aid of self-tapping sheet metal screws.
  • the metal grid which consists, for example, of expanded metal sheets with a wall thickness of 0.8 mm and openings of approximately 5 mm in width and 10 mm in length, is additionally fixed to the assembly iron 5 via connecting elements 9 in the form of wire hooks. At this point in time, the other outer surface of the component has not yet been covered by a metal grid.
  • a layer 10 of shotcrete in a corresponding thickness is applied to the metal grid from both sides, the assembly irons 5 being completely embedded in the shotcrete layer 10.
  • the openings of the metal grille must be dimensioned such that they also allow shotcrete to be applied to the vertically oriented metal grille surface.
  • Layer 10 is dimensioned as a load-bearing part of the building wall.
  • an additional insulating material layer 11 is applied, for example by a foamed plastic such as polyurethane or the like.
  • the still open outer surface of the frame is also covered with a metal grid 8, which in turn is connected to the Assembly iron 5 is set.
  • a shotcrete layer 12 is again applied in the desired thickness, whereby the second shotcrete layer, as the exemplary embodiment shows, can be thinner than the first shotcrete layer.
  • the two concrete outer surfaces can now be provided with a layer of fine plaster in a conventional manner.
  • the struts 2 are provided in the web area with recesses 13, which serve to reduce weight on the one hand and on the other hand free passage of the insulating material when foaming allow.
  • the horizontal section in Fig. 3 shows that the struts 2, but also the vertically extending parts 1 'of the frame 1 consist of a C-shaped sheet metal profile.
  • the horizontal section in FIG. 3 shows a corner connection from which it can be seen that after the components have been erected using self-tapping screws 14, the elements are firmly connected to one another.
  • a connection by welding, clamps or the like can of course also be used.
  • the horizontal section also reveals the course of the mounting iron 5 and the arrangement of the connecting elements 9 between the mounting iron 5 and the metal grid 8. Furthermore, it can be seen from the horizontal section that both the struts 2 and the vertically extending frame parts 1 'are each provided with recesses 13 through which the introduced insulating material or shotcrete can pass, as is the case for the outer frame part 1' of the wall part A. is shown.
  • the I-shaped struts 15 are again spanned with a metal grid 8, which is fixed to assembly iron 5 with the aid of wire-shaped connecting elements 9.
  • the mounting iron 5 are inserted through corresponding holes in the webs of the struts 15.
  • U-shaped sheet metal profiles 16 are fastened, which are dimensioned such that they can accommodate supporting beams 17.
  • the entire ceiling structure is fastened to the support beam 17 via the U-shaped profiles 16.
  • the struts 15 again have openings 13, so that the insulating material layer 11 applied to the inner surface of the shotcrete layer 10 extends over the entire area of the ceiling.
  • a board layer 18 serving as floor or roof is attached to the top of the supporting beams 17.
  • a floor covering or a roof skin 19 can be fastened on this board layer 18 in accordance with the intended use.
  • the space between shotcrete layer 10 and the board layer 18 can either be filled only partially, as shown here, or completely with the insulating material 11.
  • the I-shaped struts 15 can also be included in the construction as a load-bearing part of the ceiling, since despite the design as a rolled sheet metal profile, a considerable moment of inertia is available for the load bearing.
  • This has the advantage that the supporting beams 17 connected to the I-profile 15 can be dimensioned correspondingly smaller, so that overall a considerable weight saving and thus more favorable static values result for the ceiling construction.
  • FIG. 5 shows a modified embodiment of the component for the production of vertical building walls in a vertical section.
  • the structure essentially corresponds to the structure described with reference to FIG. 2.
  • the main difference from the embodiment according to FIG. 2 is that after the shotcrete layer 10 has been applied, the other outer plane of the frame is covered with a breathable film, in particular a breathable plastic film 20, and is then fixed to the frame together with the metal grid 8.
  • the space between the shotcrete layer 10 and the film 20 is now foamed from bottom to top with a foamable plastic, for example polyurethane.
  • a foamable plastic for example polyurethane.
  • the introduction of the insulating material through the usually at least semi-transparent plastic film can be observed from the outside.
  • the sprayed concrete layer 12 is applied to the metal grid from the outside with a suitably liquid sprayed concrete, the sprayed concrete passing through the openings in the metal grid and also filling the existing spaces between the metal grid 8 and the film 20.
  • This construction offers considerable advantages when introducing the insulating material compared to the surface application, as described with reference to FIG. 2.
  • a particular advantage of the construction described with reference to the exemplary embodiments lies in the fact that after the application of the usually load-bearing shotcrete layer 10 in the area of a frame level, the plastered installations, such as empty pipes for the electrical installation, water pipes, drain pipes or the like, in those to be foamed with insulating material Space can be fixed before the insulation material is foamed.
