Definitions

  • the present invention relates to a device for anchoring a covering on a diaphragm wall such as, for example, a wall or a ceiling, a floor.
  • a formwork formed from horizontal hips supported from place to place by support structures such as straight feet is produced.
  • the upper face of this formwork is covered by insulating panels, the upper face of which is previously provided with projecting anchoring means.
  • the reinforcement of the floor is then placed on these panels, then the slab is poured with a molding material such as, for example, concrete.
  • the various solutions which have been proposed so far for producing the anchoring devices can be classified into two categories, namely: the anchoring means which are incorporated into the insulation panels during their manufacture and the means of anchorage intended to be mounted on site at the time of their use.
  • the first solution makes it possible to offer a ready-to-use product at a more attractive price since it is manufactured in the factory using manufacturing means allowing high production rates to be ensured.
  • it avoids having to organize for these fixing means a distribution circuit, separate from. that of the panels.
  • it suffers from an important drawback due to the fact that the panels fitted with projecting anchoring means become difficult to store and handle. This is the reason why articulated anchoring devices have been proposed, which can be folded back against the panels, during storage and transport, and which can take a deployed position when the panels are used. It is a more expensive and less effective solution because the stress due to articulation and tilting does not allow the use of the most suitable forms to obtain a good anchorage.
  • anchoring devices which are in the form of helical springs which are partially screwed into the insulation panels, the part which emerges from the formwork being used for anchoring.
  • the object of the invention is to provide a solution which combines the advantages of the two solutions mentioned above without understanding the disadvantages.
  • an anchoring device in the form of a helical spring comprising a first part which fits into a substantially cylindrical shape and which is intended to be screwed into the insulation panel, and a second part which is inscribed in a substantially conical shape and which extends the first part by flaring, this second part being intended to s' anchor in the wall at the time of molding.
  • the conical shape of the projecting part of the panel has only a very small thickness (that of the wire used for the production of the spring).
  • the panels can be stacked without losing space.
  • the stiffness of the spring is a function of the diameter of the turns, the effort to compress the conical part of the spring will be relatively low. It is the same with regard to the punching action of the spring on the panel which compresses it during superposition.
  • the risk of damage to this panel is minimal.
  • the presence of the conical part of the spring facilitates the screwing of the device in the panels, whether it is a screwing on the site or a screwing in the factory:
  • This conical part allows a better grip to the hand and better grip when using a screwing tool.
  • the turn of the conical part may have a larger diameter than that of the turns of the cylindrical part, so that one obtains at this junction l 'equivalent of a shoulder.
  • this shoulder will come into abutment on the outside face of the panel while stopping screwing. The operator will no longer have to worry about the screwing depth.
  • Figure 1 is an elevational view of an anchoring device according to the invention.
  • Figure 2 is a schematic vertical section illustrating the principle of fixing ceiling insulation panels using anchoring devices such as that illustrated in Figure 1;
  • Figure 3 is a schematic sectional view of a stack of insulation panels fitted with anchoring devices
  • Figure 4 is an axial section of a screw cap used for fixing the anchoring devices.
  • the anchoring device 1 consists of a helical spring comprising two parts, namely:
  • first part 2 the shape of which is inscribed in a cylinder, this first part being intended to be screwed into an insulation panel, and - A second part 3 which extends the first part 2 by flaring, this second part 3 being part of a cone.
  • the first turn of the second part 3 has a significantly larger diameter than that of the first part 2.
  • the junction between the two parts is achieved by a section of wire 4 which extends radially (at the image of a shoulder).
  • This spring 1 could advantageously be made of galvanized or stainless steel wire or of polymer.
  • the panels fitted with their fixing devices are installed at the bottom of the formwork, before the reinforcement and the pouring of the floor.
  • the panels PP 2 are laid flat on a horizontal formwork table TC mounted on a support structure constituted here by straight feet PS (partially shown).
  • the springs 1 which constitute the fastening devices are screwed onto the upper wall of the panels (here the panel P so that only the second part 3 (conical) protrudes relative to said wall.
  • the operator installs the metal reinforcements AM (reinforcement) and then proceeds to pour the PL floor, for example with concrete, until the desired level is achieved.
  • AM reinforcements
  • the operator can remove the TC formwork table and its PS support structure.
  • the anchoring devices 1 can be screwed in at the factory or even on site just before installing the P 15 P 2 panels.
  • the panels P 15 P 2 , P 3 fitted with anchoring devices, can be easily stacked for storage and transport ( Figure 3).
  • Figure 4 shows a screw cap 6 which can be mounted in the mandrel of a conventional screwdriver.
  • This screwing bell 6 comprises a tubular body 7 open in its lower part and finished in its upper part by a bottom 8 extended by a coaxial rod 9 capable of coming to engage in the mandrel of the screwdriver.
  • the underside of the disc comprises an annular coaxial cavity (groove 11) of diameter substantially equal to that of said coil.
  • This cavity 11 comprises a protuberance intended to come into abutment on the end of the spring so as to be able to drive it in rotation.
  • This core 13 is biased by a spring 14 so as to naturally assume a deployed position in which it emerges outside the body 7 over a length substantially equal to that of the cylindrical part 2 of the spring, position in which it is retained. thanks to a limit stop (here a needle screw 15 which engages in an axial groove 16 of the core 13).
  • a limit stop here a needle screw 15 which engages in an axial groove 16 of the core 13.
  • the distance between the bottom of the annular cavity 11 and the lower end of the body 7 is substantially equal to the height of the conical part 3 of the spring.
  • a radial notch 17 formed on the lower end of the body 7 allows the passage of the radial section 4 of the spring wire as well as its drive in rotation.
  • the spring is guided (in particular by the core 13) and driven in rotation by the screwing bell.
  • the lower end of the body 7 and the horizontal section of the spring abut against the panel Pi and cause the end of the screwing.
  • the lower end of the core 13 may have a conical shape.
