Definitions

  • the invention relates to a building board of the type explained in the preamble of claim 1.
  • Such a building board is known from DE-A-2536731, which is produced by first pouring a concrete base plate.
  • the reinforcement cage consisting of the reinforcement mat, the displacement bodies and the rib reinforcement is then placed on this lower plate.
  • This reinforcement is assembled by hand on the construction site. The distances between the recesses must first be determined and the displacement bodies placed at these distances and secured against slipping. Then the reinforcement bars for the rib reinforcement are inserted individually and connected to the reinforcement mat. These rods must be held in position during the connection. Only then can the further concrete be poured in up to the height of the finished concrete slab. This building board is therefore relatively time-consuming and costly to manufacture.
  • the displacement body is a hollow body made of plastic with an open underside.
  • plastic displacement bodies in order to be able to withstand the weight of the poured concrete, such plastic displacement bodies must either be of relatively thick-walled design or be provided with reinforcing ribs. Their manufacture is also tied to specially equipped companies. This type of displacement body therefore makes the building board even more expensive.
  • Reinforcement meshes are known from CH-A-492098 and FR-A-15 20 032, in which elevations are molded. However, these reinforcement mats are only intended for solid concrete building boards, in which neither rib reinforcement nor displacement bodies are necessary.
  • a displacement body is known from DE-U-17 45 422, which was produced using plastic film.
  • This displacement body which is closed on all sides, has wooden disks as supports and reed or wooden slats connecting these supports, which are covered with the plastic film attached to the wooden slats.
  • This displacement body is therefore relatively cumbersome to manufacture and very expensive.
  • the invention has for its object to design a reinforced, ribbed building board so that it is less time and cost consuming to produce.
  • the sub-claim 4 describes a particularly advantageous embodiment of a reinforcement mat, in particular for producing the building board according to the invention, the zigzag or wavy longitudinal bars colliding with the tips representing a particularly advantageous possibility of making the elevations shear-resistant.
  • the reinforcing struts according to subclaim 5 bring about a further improvement in stability.
  • the feet or the foot area of the displacer can be snapped in between the additional longitudinal bar according to subclaim 6 and the adjacent longitudinal bar of a base edge. In this way, further protection against displacement of the displacement body is achieved.
  • the film-free foot area according to subclaim 7 makes it easier to put on or fasten the displacement body.
  • a ribbed concrete slab with a lower plate 1, an upper plate 2 and ribs 3 can be seen, which is cast monolithically from concrete.
  • the ribs 3 form the lateral delimitation of recesses, which are brought about by displacement bodies 4, which are only shown schematically here.
  • the term “recess” is used to define a concrete-free space, which is also complete, for example with Foam plastic or lightweight concrete, can be filled.
  • a hollow-profile displacement body described in more detail under FIG. 5, made of a metal lattice work covered with plastic film is used.
  • the lower plate 1 is provided with a reinforcement mat 5 made of longitudinal bars 5a and crossbars 50.
  • the reinforcement mat 5 has alternating flat areas 6 and elevations 7.
  • the flat areas 6 are expediently dimensioned such that the displacement bodies 4 are accommodated between the elevations 7 with almost no displacement and thus their position in the finished building board is fixed.
  • the elevations 7 are created by triangular unfolding of the reinforcement mat 5.
  • the height of the surveys 7 depends u. a. according to the height of the displacement bodies 4 and according to the static load on the ribs 3.
  • Fig. 2 shows a section through a building board according to the invention, in which the top plate 2 is also provided with a reinforcement mat 8.
  • the upper reinforcement mat 8 is flat and can be connected to the tips of the elevations 7.
  • reinforcing struts 9 run across the lower open side of the elevations 7, parallel to the transverse bars 5b in the plane of the flat areas 6.
  • the reinforcing struts 9 are connected to the flat areas 6 in a suitable manner, for example by welding, and keep the width of the lower open sides of the elevation 7 constant even under load.
  • it is not absolutely necessary that the reinforcing struts are welded on both sides of each unfolding. In principle, two welds are sufficient, which are attached on both sides of all folds.
  • FIG. 3 shows a particularly preferred embodiment of the reinforcement mat 5 consisting of crossed longitudinal and transverse bars 5a and 5b.
  • One of the longitudinal bars 5a is located at the top and at the base edges of the triangular unfolding 7. Between the longitudinal rod at the tip and those on the base edges of the unfolding 7, a zigzag or wavy longitudinal rod 5'a is attached.
  • An additional longitudinal rod 5 "a runs parallel and at a distance from the longitudinal rods of the base edge. The type of attachment and the function of these longitudinal rods 5" a are explained below in connection with the description of FIG. 5.
  • FIG. 4 shows the reinforcement mat 5 before the deformation.
  • the reinforcement mat 5 is produced in such a way that the longitudinal and transverse bars 5a, 5'a, 5 "a and 5b are first connected to one another to form a flat reinforcement mat.
  • the straight longitudinal bars 5a are located next to one another at such a distance that the later flat areas 6 correspond to the dimensions of the displacers 4, and that one of the longitudinal bars 5a continues to lie on each edge of the later triangular fold 7.
  • the longitudinal bars 5'a which are expediently produced by bending or running in a zigzag pattern are on both sides of the longitudinal bar later forming the tip of the fold 7, the corresponding curvatures of the two longitudinal bars 5'a of a fold 7 being able to collide at the tip.
  • the bends of the longitudinal bars 5'a cover the entire area between the longitudinal bar at the tip and the associated basic longitudinal bar If necessary, parallel and at a distance to the longitudinal bars of the Base edges the additional longitudinal rods 5 "a are provided for snapping the displacement body 4. During the subsequent welding of the reinforcement mat, special care must be taken to ensure that each of the curvatures of the longitudinal bars 5'a is connected to the adjacent straight longitudinal bar. Then the elevations 7 are unfolded. If necessary, the width of the lower open side of the unfolding 7 and thus its height is fixed by the reinforcing struts 8 attached to suitable flat areas 6.
  • the displacement body 4 is formed here by a hollow profile made of latticework 10 and a plastic film 11 that is open at the bottom.
  • the latticework 10 consists of a structural steel mat brought into the shape of the displacer 4.
  • the plastic film 11 was attached by shrinking on.
  • the displacement body 4 has a film-free foot region 12.
  • the foot area 12 was inserted between the basic longitudinal bar and the additional longitudinal bar 5 "a through the reinforcement mat 5. If necessary, the displacement body 4 can be fixed in this position either by wire or by welding.
  • the additional longitudinal bars 5" a can be or be attached to one side of each flat area 6, which receives a displacement body 4.
  • the distance to the adjacent basic longitudinal bar depends on the dimensions of the foot area 12 or other walls or feet of the displacement bodies 4 to be snapped in.
  • the additional longitudinal bar 5 "a can also rest on the side of the transverse bars 5b facing the displacement body. In this way also a hollow profile displacement body with an unbroken wall can be held.
  • the invention is not limited to the described embodiments. So z. B. the form of the surveys can be varied, if this appears appropriate. Furthermore, the zigzag longitudinal rod does not necessarily have to be made by bending.
  • the displacer made of latticework and plastic film can also be used without the film-free foot area. In this case, it is placed on the flat area and held, for example, with wire.
