Definitions

  • the invention relates to an end profile for a flat roof building with a concrete ceiling, which rests on the masonry of a building and is surrounded in the region of the roof edge by the end profile designed as a formwork body.
  • the invention has for its object to provide an end profile with which the assembly work in the manufacture of the concrete ceiling can be reduced. If possible, components should be used which are largely prefabricated and assembled in a simple manner in the factory and which can be easily assembled at the construction site. Such components should also be able to be produced from suitable, inexpensive, easily and quickly processed materials and should be able to be adapted to the thickness of the concrete ceiling in a simple manner if possible.
  • each formwork body is a foamed plastic part, in which a plurality of parallel holding plates are arranged at intervals from one another, each holding plate having a surface area acted upon by the plastic foam and a surface area acted upon by the concrete of the concrete ceiling and in which the Surface area impinged on plastic foam has a plurality of openings for the passage of plastic foam during foaming, and also has a plurality of fastening holes in the surface area impinged on by the concrete for inserting reinforcing bars.
  • Each formwork body is preferably a plastic part foamed from two different plastics, bodies made of polystyrene being arranged in the spacings between the holding plates, which are completely surrounded by layers of polyurethane acting on the holding plates.
  • This choice of plastics makes it possible to use only small amounts of the more expensive polyurethane, while the largest amount of plastic consists of the cheaper polystyrene. This also lowers the weight because a polystyrene foam lighter than the polyurethane foam is used.
  • foaming with the polyurethane surrounding the polystyrene bodies in a mold only takes a short time, since the layers of the polyurethane foam harden quickly in the mold.
  • Each formwork body is preferably designed to be divided in the vertical direction, the holding plates having eyelets in the region of their lower horizontal edges, into which holding plates located below are hooked in, which are located in the region of their upper horizontal edges.
  • This design makes it possible to assemble the formwork bodies as desired from several individual formwork bodies, the hooks of the lower holding plates being hooked into the eyelets of the holding plates above.
  • the entire formwork body can be adapted in this way to the thickness of the concrete slab to be cast.
  • One of the parallel holding plates of a formwork body is preferably arranged on each end face intended for connection to an adjacent formwork body.
  • One of the advantages that can be achieved with the invention is that the formwork body into which the edge of the concrete ceiling projects does not have to be removed again like a conventional formwork after the concrete has set.
  • the formwork body also serves as formwork for the edge area of the concrete ceiling and as its structural conclusion in the finished state. It contains the necessary insulation layers, which ge from the plastics be formed and are already made in the factory by simple foaming. Other required components, such as ledges, can be easily attached to the formwork body after the concrete has set.
  • the formwork body also has sufficient static strength for fastening the ledge cover on the one hand and for the edge-side limitation of the concrete ceiling to be created and the plastic foils with an insulating layer on the top and covering the concrete ceiling.
  • the roof of a flat roof building consists of a concrete ceiling 10, which is supported on the masonry 11 of the building.
  • the concrete ceiling in the embodiment according to FIG. 1 projects over the masonry 11 and carries a formwork body 12a.
  • the flat roof building is equipped with a facing wall 13, which is made of clinker bricks. It forms the outer wall of the building, and the formwork body 12a connects to its upper end.
  • An air space 14 is provided between the facing wall 13 and the masonry 11, to which an insulating layer 15 adjoining the masonry 11 is connected.
  • the formwork body 12a is assembled from a plurality of parallel, vertical holding plates 34 and a holding strip 35, to which the holding plates 34 are screwed at intervals from one another by means of screws 36. Then the holding plates 34 and the holding strip 35 are partially foamed in a mold with plastic 37, as a result of which the casing body 12a is formed as a shaped piece.
  • the holding strip 35 and the holding plates 34 give this molding the required strength and rigidity.
  • Each holding plate 34 has a surface area 38 which is acted upon when foaming plastic 37.
  • the remaining surface area 39 which is not acted upon when foaming, is later acted upon by concrete at the construction site when the concrete ceiling 10 is poured.
  • a plurality of openings 40 and 41 are provided in the surface area 38 in order to allow the plastic to pass through the holding plate 34 during the foaming process.
  • the surface area 39 contains fastening holes 27, through which reinforcing bars 28 of the concrete ceiling 10 are inserted before they are poured. In this way, the formwork bodies 12a are fixed to the edge of the concrete ceiling 10 via their retaining plates 34.
  • Each formwork body 12a has a holding plate 34 on its end face facing the adjacent formwork body 12a, so that screws 43 can be inserted through two corresponding, aligned bores 42 of two adjacent formwork bodies 12a in order to fasten the formwork bodies 12a to one another.
  • a perpendicularly bent horizontal tab 44 is formed on the vertical holding plate 34 and contains a vertical bore 45.
  • the screw 36 is inserted through the bores 45 and screwed into the retaining strip 35.
  • the holding strip 35 is preferably made of wood.
  • An insulating layer 23 is arranged above the concrete ceiling 10 in the central area which is not filled by the formwork body 12a. Art is used to seal the building Fabric films 24 and 25 are provided which surround the insulating layer 23 and the casing body 12a. All insulating layers and plastic films thus ensure good heat and sound insulation and a good seal against moisture in the building, in particular also the connection area between the concrete ceiling 10 and the masonry 11.
  • the particular advantage of the firm, precisely determinable static hold of the formwork body can be achieved.
  • the casing body 54 according to FIG. 5 is composed of two partial bodies which are arranged vertically one above the other. It can be changed in height with the aid of a further partial formwork body 55 and set to a greater thickness of a concrete ceiling 10. that keep a distance from each other.
  • 61 and 62 are at this distance the body 59 from a foamed plastic, for example polystyrene and layers 63, 64, 65 and 66 from another from e g-foamed plastic, for example polyurethane.
  • the bodies 59 to 62 are each completely surrounded by the associated layers 63 to 66, these layers also acting on the holding plates 56 to 58.
  • the holding plates 56 and 58 have eyelets 67 in the region of their lower horizontal edges, while the holding plates 57 and 58 are provided in the region of their upper horizontal edges with hooks 68 which can be hooked into the eyelets of the holding plate located above them.
  • the holding plate 57 and 58 are provided in the region of their upper horizontal edges with hooks 68 which can be hooked into the eyelets of the holding plate located above them.
  • This insertion of an additional partial formwork body 55 into the formwork body 54 then causes the free vertical holding plate surface to be enlarged, the lengthening of this surface leads to the possibility of being able to cast a thicker concrete ceiling 10 corresponding to this height.
  • the formwork bodies 54 are provided with continuous horizontal channels 69 through which moist air can be discharged to the outside from the finished roof edge area of the roof.
  • the holding plates 56 of the formwork body 54 each have horizontally protruding pins 70 on a vertical edge, on which, for example, a ledge covering the roof edge area can be mounted.
  • the holding plates 56 to 58 have surface areas 71, which are applied when foaming plastic of the layers 63 to 66.
  • the remaining surface areas 72 which are not acted upon during foaming, are later acted upon by concrete at the construction site when the concrete ceiling 10 is poured.
  • a plurality of openings 73 are provided in order to allow the plastic to pass through the holding plates 56 during the foaming.
  • the surface area 72 also contains fastening holes 74 through which reinforcing bars of the concrete ceiling 10 are inserted before it is poured. In this way, the formwork bodies 54 are held on the edge of the concrete ceiling 10 via their holding plates 56.
  • the formwork bodies 54 and 55 are produced by casting in molds. First, the holding plates 56 to 58 are fixed in the respective shape, then the bodies 59 to 62 are arranged between the holding plates in the respective shape, and finally the layers 63 to 66 are foamed, which completely surround the bodies 59 to 62 and the holding plates Act on 56 to 58 on both sides. Before that, cores were also placed in the mold, which create the channels 69.
