Definitions

  • the present invention relates to a method of producing facades, roofs and floors by assembling a series of self-supporting panels resistant to fire.
  • the upper surface of the formwork is provided with means forming this connection between the steel and the concrete, in order to reduce the stresses of grazing forces between steel and concrete.
  • the connecting means take the form of small ribs.
  • This type of formwork has many disadvantages in the manufacture of the floor on site, both in terms of installation speed and quality of implementation. In addition, it does not allow for vertical structures such as facades or even inclined structures such as roofs. Finally, its fire resistance and mechanical characteristics are not optimal.
  • the panel consists of a single module and a concrete layer covering the entire surface of said thermal insulation layer and completely surrounding said metal reinforcing element.
  • the panel consists of two modules and a concrete layer covering the entire surface of each of the thermal insulation layers and completely surrounding each of the metal reinforcing elements.
  • the self-supporting panel according to the invention can be used in horizontal position, vertical or oblique, for the realization of structures mentioned above.
  • the set of orientation characteristics described refers to a panel placed horizontally on the ground. If the panel were placed vertically, it would naturally replace the horizontal terms by vertical and vice versa in the description of this panel.
  • a self-supporting panel 1 consisting, on the one hand of a module 2 and on the other hand of a concrete layer 3.
  • the module 2 comprises a U-shaped metal section 4 which here consists of 'galvanized steel.
  • This section 4 consists of a central zone 5 substantially horizontal and extended at both ends by webs 6 and 6 '.
  • These souls 6 and 6 ' are themselves extended by a substantially horizontal sole 7, respectively 7'.
  • the sole 7 is oriented towards the inside of the panel 1, while the sole 7 'is oriented towards the outside of this panel 1.
  • a block of rock wool 8 which is in section in the form of a six-sided polygon and which has in particular a large thickness in its central part, which decreases going towards the edges of the block.
  • This block has a maximum thickness less than the height of the profile 4.
  • FIG 2 it can be seen a second embodiment of a self-supporting panel 10 according to the invention, which consists, on the one hand of two modules 11 and 12, and on the other hand a layer of concrete 13 covering and solidarisant the two modules 11 and 12.
  • the modules 11 and 12 are identical to the module 2 which has just been described for the first embodiment.
  • each panel 20, 21 comprises a metal section 20 ', 21' which comprises interlocking ribs 20 ", 21" which are of different but complementary conformation and make it possible, after they have been brought into contact, to avoid any respective movement of the panels 20 and 21 in a direction perpendicular to that of the plane of the panels 20 and 21.
  • the panel 20 is also provided with two seals 22 and 23 which will ensure a seal between the panels 20 and 21, after assembly.
  • the panel according to the invention has an improved fire resistance, whatever its disposition with respect to the direction of propagation of the fire.
  • the geometric shape of this profile ensures, through the souls, a connection between the metal face of the panel and its concrete face.
  • This link is essential in the behavior of the system during a fire. Indeed, the exposed metal face in this case quickly has more resistance, but can remain stable for several hours and provide a screen role.
  • connection between the concrete face and the metal face is mechanically reinforced by the metal reinforcing element welded or connected by another system to the webs of the profile and embedded in the thickness of the concrete layer.
  • the rock wool contained in the self-supporting panel is a real fire screen and especially the temperature rise of the unexposed face. Not being directly exposed to fire, its mechanical stability is ensured for several hours.
  • the concrete layer not being subjected to the flame and little to the rise in temperature, is not concerned by the fire on the other side.
  • the operation is mechanically identical to the previous case, with the difference that the thickness of the concrete layer is sufficient on its own, to withstand for at least two hours. This configuration is therefore even more favorable to the good behavior of the panel exposed to the fire.
  • the rockwool also provides the same heat shield function and considerably limits the temperature transfer between the exposed face and the non-exposed one.
  • the panel according to the invention differs in particular formwork of the prior art in that it is self-supporting and can be manufactured in the workshop, then easily routed to the site or it can be installed immediately by assembling the prefabricated panels.
  • the panel according to the invention also has the advantage of being used both for facades, for floors or roofs, which allows to have a single panel model in stock for the realization of these structures.
