Definitions

  • German published patent application DE-A-2 116 479 describes spherical core bodies for concrete slabs, each of which is provided with two through holes intersecting at right angles in the center of the body.

  • EP-A-0 552 201 describes a hollow floor slab with reinforced concrete in a two-dimensional structure, in which each closed plastic hollow sphere is individually in a reinforcement lattice network of steel rods are captured equally spaced in both vertical directions.
  • the reinforcement grid network consists of an upper, essentially planar network which is connected by wires or the like to a lower, essentially likewise planar network. It is essential for the implementation of the invention known from EP-A-0 552 201, according to the information given there, that the displacement bodies protrude into the upper and the lower reinforcing grid network. This not only appears to be unnecessary, but also disadvantageous, since it prevents an odularity of the design principle and this must be produced exclusively by means of specially produced grids with correspondingly dimensioned grid openings for the displacement bodies.
  • Adapted lattice girders are also required, which must be inserted exactly between the lower and the upper reinforcement. Since the hollow bodies form a unit with the load-bearing reinforcement and the lattice girders, only project-related manufacture is possible. This means that a separately dimensioned and calculated latticework must be made for each type of flat ceiling to be produced.
  • Light body can be installed as this area for Strength of the blanket is not able to make any significant contribution and therefore a weight saving is possible and sensible.
  • the invention is based on the object of simplifying the flat ceiling module mentioned at the outset.

  • tools are to be proposed which enable a simplified and, in particular, modular production method for concrete parts.
  • Corresponding concrete parts should also be proposed. It is desirable for the invention that flexible recesses in the cross-section of the ceiling for the installation of pretension, ventilation ducts, heating lines, cooling lines, electrical lines, sanitary lines etc. are modularly possible and can be provided.
  • the invention solves the problem by a method according to The first step of the measures of the invention is that the proposed method enables semi-finished concrete products to be produced in series or virtually in series. Furthermore, the modules with the displacement bodies can be mass-produced largely independently of the masses of the later semi-finished products and the finished ceilings.
  • a hollow body strip from the latticework with a linear row of the displacement bodies is independent of the static and dynamic properties of the flat ceiling and - in relation to the hollow body strip - is self-supporting.
  • the invention preferably decouples the function of the concrete displacement by the displacement body from the load-bearing function of the reinforcement. The invention thus becomes independent of the properties of the respective project and enables rational production of standard modules which only need to be cut to the desired length on the construction site or in the precast plant.
  • a project-related arrangement of the hollow body strips makes it possible for flexible recesses in the cross-section of the ceiling for the installation of prestressing, ventilation ducts, heating lines, cooling lines, electrical lines, sanitary lines, etc. to be modular and possible.
  • the dimensioning of the bars forming the lattice is only determined by the fact that the module with the relatively light displacement bodies remains self-supporting.
  • the module is therefore relatively light in weight and can be manipulated with light dishes.
  • the module according to the invention is simply placed on the fully calculated flat slab board and, if necessary, connected to the reinforcement only to the extent that this is necessary to fix the module in position. However, the module is preferably pressed or shaken into the concrete that can still be processed. Welding work is not necessary to carry out the invention either in the precast plant or at the construction site. If a flat ceiling board requires the placement of several parallel modules, these do not have to be connected to each other.
  • the rods can be made of structural steel or plastic or other materials. Then the module or the modules and the flat ceiling board are poured together with concrete.
  • the displacers can either consist of hollow bodies such as hollow spheres, hollow half-shells open or closed at the bottom, hollow ellipsoids or hollow cuboids or hollow cubes or similar shapes made of plastic or similar, or of a solid material of the mentioned or other geometric figures, which is much lighter than concrete.
  • the module according to the invention can be designed in such a way that it has a plurality of parallel strips which are connected to one another in order to fix the relative position to one another.
  • the cross-sectional shape of the latticework can expediently be adapted to the position of the respective reinforcement for the flat slab in order to be able to conveniently fix the module or modules to the reinforcement.

Abstract

La présente invention a pour objet de faciliter et de simplifier la production de revêtements en béton au moyen de corps de déplacement. A cet effet, les corps de déplacement se présentent par ex. sous la forme de balles en plastique (240) ou de demi-coques en plastique, et sont enfermés dans des réseaux de grille (230) ouverts sur un côté, de préférence sur le dessous, et ces modules sont alors comprimés dans une première ou une seconde couche de béton qui contient déjà une première plaque d'armature, puis le produit semi-fini ainsi obtenu est recouvert d'une masse de béton au cours d'une étape de finition ultérieure.
