Definitions

  • the invention relates to a component for the production of reinforced concrete ceilings or reinforced concrete walls, having a base plate, a reinforcement assigned to the base plate and a spacer connecting the reinforcement to the base plate and fixed to the base plate.
  • Components of the type in question have been known from practice for some time.
  • EP 0 164 330 B1 already discloses a prefabricated formwork element for the production of reinforced concrete slabs, which essentially consists of a building board with reinforcement.
  • the steel lattice girders of the reinforcement are supported by structurally complex brackets.
  • the holders are mushroom-shaped and non-positively connected to the building board. These holders are gripped by longitudinal or tension rods.
  • two tension rods running essentially parallel to one another are placed on the "mushroom heads" of the holders and snap behind the mushroom head after a pressing force has been applied. This creates an inseparable connection between the reinforcement and the brackets.
  • a disadvantage of this formwork element is the complicated construction of the holder, which is associated with high production costs.
  • the high manufacturing costs also increase the overall costs of the formwork element or the ceiling to be manufactured.
  • the manufacturing outlay of the known formwork element itself is complex. First of all, it is necessary to place the holder on the building board at a correct distance, then screw it to the base plate in order to then mount the reinforcement. As a result, several operations are required to produce a known formwork element. Connected with it also a significant amount of time, which in turn increases costs.
  • the invention is therefore based on the object of specifying a component for the production of reinforced concrete ceilings or, if appropriate, reinforced concrete walls, in which a quick and easy installation of the reinforcement on a base plate is possible using simple technical means.
  • the component according to the invention is characterized by the features of claim 1.
  • the component in question is then designed such that the spacer is an integral part of the reinforcement.
  • the component according to the invention has the enormous advantage that a production line for producing the spacer as an individual part is completely eliminated. In addition, the time-consuming process of positioning any spacers on the base plate is eliminated before the reinforcement can be installed.
  • the reinforcement includes at least one lattice girder.
  • the lattice structure Part of the lattice girder advantageously formed as a spacer.
  • a spatial lattice girder is preferably used, which can be attached to the base plate in a statically stable manner.
  • the lattice girder can now be designed in different ways. For example, two grille strips can be connected in the sense of a V-profile. Other types of profiles such as U or X profiles would be conceivable. With regard to a structurally particularly stable configuration of the lattice girders, it is expedient if the opening areas of the lattice girders point towards the base plate.
  • the spacer is further advantageously formed by extensions of lateral retaining webs of the lattice girder. Due to its extensions, the lattice girder itself serves as a spacer.
  • the spacers or the extensions are angled outwards in relation to the lateral holding webs of the lattice girder.
  • the retaining webs of the lattice girder could be subjected to a bending process.
  • the outer angle between the lateral holding webs and the extensions expediently has an amount that allows the free ends of the extensions to rest on the base plate so that a fastening can be carried out there.
  • the outer angle between the holding web and spacer or extension has an amount between 90 ° and 180 °.
  • An angle of approximately 150 ° is preferred, since a larger angle means that the free end is less accessible of the spacer or the extension leads and a larger bending moment would occur on the extension due to an angle with a smaller amount.
  • the angled extensions should establish a sufficient distance of at least 30 mm between the lateral support bars of the lattice girder and the base plate.
  • the spacers or the extensions and thus at the same time the lattice girder or the reinforcement are fastened to the base plate in one operation.
  • the attachment is preferably non-positive.
  • staples are used as fasteners, which only require fast, simple clamping processes.
  • it could also be screwed or riveted.
  • an inseparable or detachable connection is made between the base plate and the extensions acting as spacers.
  • a particularly preferred embodiment of a lattice girder which also acts as a spacer through the extensions provides for the lattice girder to be equipped with tension rods which represent the main reinforcement of the structural element according to the invention.
  • tension rods now come into effect in the tension zone, they are arranged above the distance specified by the extensions of the lattice girder.
  • lower tie rods could be assigned to the angled area between the lateral holding webs and the extensions.
  • An upper tension rod in a zone of increased tensile force application could advantageously form the apex of the lattice girder.
  • the tension rods and the lattice girder are expediently non-detachable and non-positively connected, preferably by welding.
  • additional reinforcement could be provided.
  • This additional reinforcement could have cross bars to achieve a uniform load-bearing effect.
  • the additional reinforcement could consist of individual structural steel bars or could also be used as a steel mat consisting of transverse and longitudinal bars in the sense of a grid and, for example, attached to the base plate by means of special spacers.
  • the steel mat or the lattice with the special spacers only have to be placed on the base plate, forms through its grid-like division, so to speak, a template for supporting the lattice girder and is also, in an inventive manner, by fastening the lattice girder attached with the extensions. Consequently, the component according to the invention not only allows simple attachment of the spacer and the reinforcement in one operation, but also the assembly or attachment of the spacer and thus also the reinforcement and the additional reinforcement in a single operation.
  • both ceilings and walls can be produced from several components according to the invention. With regard to minimizing the construction time, it is particularly advantageous to prefabricate the components so that they can be installed directly on the construction site.
  • the base plate With regard to a reduction in interior construction work, it is particularly favorable if the base plate remains in the building in the sense of lost formwork. In this way, the walls or the ceilings can be designed directly without the need for interior plastering. In this context, it is particularly advantageous to manufacture the base plate from wood-based material. E.g. come polyurea-bound wood-based panels into consideration, which are biologically harmless and also recyclable. Furthermore, the use of wood wool cement boards or plastic boards would be conceivable.
  • two components according to the invention with their reinforced surfaces could also be arranged at a distance from one another.
  • the lattice girders could be designed as connecting pieces. In the case of lattice girders that meet precisely, latching devices could be provided, for example.
  • the lattice girders of the opposite base plates could, however, also be assigned offset in such a way that the protruding end of a lattice girder in each case strikes the opposite base plate and can be fixed from the side of the base plate facing away from the lattice girder, quasi from the outside.
  • the respective protruding end of the lattice girder could now be provided with a flat element in which screws or other fastening means can engage.
  • the flat elements or the contact surfaces of the lattice girders acting as connecting pieces could be predrilled.
  • Self-tapping screws that can be easily rotated through the chipboard could be used for screwing.
  • the component 1 and 2 show an embodiment of a component 1 according to the invention, which can be used both for the production of reinforced concrete ceilings and for the production of reinforced concrete walls.
  • the component 1 has a base plate 2, which is assigned a reinforcement 3 on one side, which over a spacer 4 is fixed on the base plate 2.
  • the reinforcement 3 comprises a lattice girder 5.
  • the spacer 4 is realized at a defined distance from the base plate 2 by an extension belonging to the lattice girder 5. The extension therefore functions as a spacer 4 and is an integral part of the lattice girder 5.
  • the lattice girder 5 is designed as a spatial lattice girder in this exemplary embodiment.
  • two flat lattice strips are connected to one another in such a way that an essentially V-shaped lattice girder profile is created.
  • the lattice girder 4 has lateral holding webs 6, to which the spacers 4 or the extensions are connected, in that they are angled outwards.
  • the outer angle ⁇ formed by the holding webs 6 and the spacers 4 or the extensions in the outwardly facing region of the lattice girder 5 is dimensioned such that the free ends of the spacers 4 or the extensions rest on the base plate 2.
  • staples 7 are used as fastening means. Due to the angled course of the spacer 4 or the extension, its or its free end is easily accessible. In addition, the actuation of a shooting device for cramps requires little time.
  • the essentially U-shaped Staples 7 penetrate with their sharpened legs into the base plate 2 made of wood-based material and, as shown in dashed lines in FIG. 1, are advantageously spread apart during the shooting-in or during the progressive penetration into the base plate 2, so that a safe, essentially unsolvable , ie connection that can only be released with very great effort.
  • tensile or longitudinal rods 8, 9 and 10 are provided, which are arranged in a special way on the lattice girder 5. From Fig. 1 it can be seen that the tie rods 9 and 10 are arranged in the angled, outer region between the holding webs 6 and the spacers 4 and the extensions and that the tie rod 8 is connected to the end of the lattice girder 5 protruding from the base plate 2 is.
  • the tension rods 8, 9, 10 are arranged above the extensions acting as spacers 4.
  • the additional reinforcement 12 comprises a grid formed from cross bars 11 and longitudinal bars 13, which lies on the base plate 2 via special spacers 14.
  • the spacers 4 or the extensions of the lattice girder 5 overlap a longitudinal bar 13 and pass through the open spaces formed by the cross bars 11 and the longitudinal bars 13, so that the reinforcement 3 and, at the same time, the additional reinforcement 12 can be fastened via the spacers fastened by means of the clamps 7 4 or the extensions are made.
  • the special spacers 14 serve only for the spaced support of the grid and are not separately attached to the base plate 2.
  • the base plate 2 remains as lost formwork in the building.
  • the size and geometry of the components according to the invention is primarily determined with a view to easy handling.
  • teaching according to the invention is not limited to the exemplary embodiment discussed above. Rather, the teaching according to the invention can also be implemented in the case of components or prefabricated components with a different type of reinforcement.
