Definitions

  • the present invention relates to the field of public works and civil engineering, in particular the production of steel frame concrete slabs, for example for bridges and buildings, and relates to a method of securing a mass of material to a functional support.
  • the invention also relates to devices obtained by implementing this method.
  • Steel-framed concrete slabs called mixed frameworks are generally made up of steel beams and reinforcement and concrete, the whole being cased and poured on site.
  • the drawback of such a process lies in the fact that it requires a relatively long production time, the construction not being industrialized and being subjected to climatic vagaries and to the concrete hardening period which is 28 days.
  • the material used for the support profiles is generally not used to the maximum of its possibilities, after installation, the upper part of these profiles, linked to the concrete, being little stressed mechanically, while the lower part of the profile is tense.
  • the upper part of the profile is only necessary during the short period when the profile must carry the soft concrete, and constitutes a stiffening intended to prevent its spillage or buckling and serves to retain the lost formwork.
  • connection between the support profile and the reinforcement of the concrete slab is often ensured by an attached connector, fixed by welding to the support profile.
  • an attached connector fixed by welding to the support profile.
  • Such an embodiment is relatively expensive, because it requires careful welding of said connectors.
  • the present invention aims to overcome these drawbacks.
  • the invention also relates to devices obtained by application of this method, characterized in that they essentially consist of a concrete slab, 1 frame of which is connected to support profiles by means of connectors forming an integral part of said profiles and embedded in the concrete and in that they are preferably molded in the inverted position.
  • the method of securing a mass of material to a functional support is characterized in that it consists essentially to make a reusable formwork 9 of the upper part of the slab and to assemble, turned upside down, all of the reinforcing elements 1 connected together and to the support profiles 2, the reinforcing elements 1 being mounted transversely to the profiles 2, in said formwork, the support profiles 2 being held so as to present essentially their connection part 3 to the reinforcements 1 in the volume of the formwork 9 to be filled with concrete 4.
  • connection between the reinforcement 1 and the sections 2 is made in the submerged part of said sections 2, which are functionally linked to the mass of the concrete 4 via the reinforcements 1.
  • the invention also relates to devices obtained by application of this method, characterized in that they essentially consist of a concrete slab 4, the reinforcement 1 of which is connected to support profiles 2 by means of connectors 3 forming an integral part of said sections 2 and embedded in the concrete 4, these devices being preferably molded in the inverted position.
  • Such an embodiment of the device makes it possible to obtain a perfectly flat upper face and an arrangement of the frame 1 in the formwork without requiring spacers, said frame 1 being suspended from the profiles 2 by means of the connectors 3 which are embedded in the concrete 4, so that the positioning of said reinforcement can be carried out much more precisely and without the insertion of foreign bodies.
  • Profiles 2, which are generally metal profiles, are intended to be placed on linear or point supports constituting bridges, floors or other walls, and are most often in the form of elements of a few meters or a few tens of meters long associated, individually or in number, with a concrete slab 4 a few meters wide.
  • Each support profile 2 comprises a connection part 3 in one piece with the profile 2 and provided, at regular intervals, with cutouts 5 intended to cooperate with the reinforcing elements 1 with a view to housing and / or fixing of these, while ensuring the triangulation of the profile 2 between the sole of said profile 2 and the concrete slab 4.
  • cutouts 5 thus achieve the positioning and spacing of the reinforcing elements 1 in two or three dimensions.
  • the embodiment of the profiled support 2 and of its connection part 3 in a single piece makes it possible to eliminate the subsequent welding operations from part 3 to part 2.
  • connection part 3 makes it possible to reduce the various mechanical bending and shearing stresses of the reinforcing elements 1, which oppose the displacement of the mass of material formed by concrete 4, via said connection part 3, on the support profiles 2.
  • all of the internal and / or external multi-dimensional forces exerted on a slab and due, in particular , slipping, lifting and tearing can be resumed.
  • connection part 3 embedded in the concrete slab 4 participates, in fact, usefully in the resistance to bending of the support profile 2, which can, therefore, be undersized with respect to its dimensioning. origin.
  • connection part 3 has a constant section and extends in a rectilinear manner on the support profile 2 and its cutouts 5 are in the form of opposite hooks cooperating by their bottom with the reinforcing elements 1 freely placed in said hooks.
  • the reinforcing elements 1 can easily be put in place in the cut-outs 5 of the connection parts 3 of the profiles 2 after the latter have been disposed in an inverted position above the formwork, by simple engagement in the hooks opposite forming said cutouts 5, said hooks holding the reinforcing elements 1 against falling into said formwork.
