Description

La présente invention concerne un procédé de réalisation de façades, toitures et planchers par assemblage d'une série de panneaux autoportants résistants au feu.The present invention relates to a method of producing facades, roofs and floors by assembling a series of self-supporting panels resistant to fire.

Il est connu des brevets FR 2 333 107 ou EP 1 215 346 A1 un coffrage métallique pour l'exécution de construction en béton, telle qu'un plafond acoustique. Ce coffrage métallique perforé est mis en place sur le chantier, où l'on pose un treillis métallique sur les extrémités du coffrage, avant de couler du béton sur l'ensemble de la surface à réaliser.It is known patents FR 2 333 107 or EP 1 215 346 A1 a metal formwork for the construction of concrete construction, such as an acoustic ceiling. This perforated metal formwork is set up on site, where a metal mesh is placed on the ends of the formwork, before pouring concrete on the entire surface to be made.

Afin d'assurer une liaison entre le coffrage et la dalle en béton, la surface supérieure du coffrage est munie de moyens formant cette liaison entre l'acier et le béton, afin de réduire les tensions d'efforts rasants entre acier et béton. Dans ce document, les moyens de liaison prennent la forme de petites nervures.In order to ensure a connection between the formwork and the concrete slab, 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. In this document, the connecting means take the form of small ribs.

Ce type de coffrage présente de nombreux inconvénients au niveau de la fabrication du plancher sur chantier, tant en terme de vitesse de pose que de qualité de réalisation. En outre, il ne permet pas de réaliser des structures verticales telles que des façades ou bien encore des structures inclinées telle que des toitures. Enfin, sa résistance au feu et ses caractéristiques mécaniques ne sont pas optimales.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.

Un procédé similaire à celui de la présente invention est décrit dans le brevet FR 2 219 284 A .A method similar to that of the present invention is described in the patent FR 2 219 284 A .

Le but de la présente invention est donc de remédier aux inconvénients des réalisations de l'art antérieur, en mettant à disposition un panneau autoportant polyvalent, présentant une grande résistance au feu ainsi qu'une bonne résistance mécanique et une grande facilité de mise en oeuvre sur chantier pour la réalisation de structures variées.
A cet effet, l'invention a pour premier objet un panneau autoportant résistant au feu, pour le bâtiment, constitué, d'une part, par un ou plusieurs modules comportant :

  • un profilé métallique en forme de U comprenant une plage centrale horizontale s'étendant dans le sens longitudinal du profilé, deux âmes latérales sensiblement verticales comportant des nervures d'emboîtement, et prolongeant chaque côté de la plage centrale et deux semelles sensiblement horizontales venant prolonger chacune des âmes latérales, ledit profilé étant éventuellement muni d'un revêtement de protection contre la corrosion,
  • un élément de renfort métallique sensiblement horizontal s'étendant entre les âmes du profilé, solidarisé avec ledit profilé métallique,
  • une couche d'isolant thermique disposée en appui sur ladite plage centrale, entre lesdites âmes, et sous ledit élément de renfort métallique, ledit isolant thermique étant constitué de laine de roche,
et d'autre part, par une couche de béton recouvrant toute la surface de ladite ou lesdites couches d'isolant thermique et entourant entièrement ledit ou lesdits éléments de renfort métallique.The purpose of the present invention is therefore to overcome the disadvantages of the embodiments of the prior art, by providing a versatile self-supporting panel, having a high fire resistance and good mechanical strength and ease of implementation on site for the realization of various structures.
For this purpose, the invention firstly relates to a self-supporting fireproof panel, for the building, constituted, on the one hand, by one or more modules comprising:
  • a U-shaped metal section comprising a horizontal central zone extending in the longitudinal direction of the profile, two substantially vertical lateral webs having interlocking ribs, and extending each side of the central zone and two substantially horizontal soles extending each lateral webs, said section possibly being provided with a protective coating against corrosion,
  • a substantially horizontal metal reinforcing element extending between the webs of the profile, secured to said metal section,
  • a layer of thermal insulation disposed in abutment on said central zone, between said cores, and under said metal reinforcing element, said thermal insulation being made of rockwool,
and on the other hand, by a concrete layer covering the entire surface of said at least one layer of thermal insulation and completely surrounding said metal reinforcing element or elements.

Dans un mode de réalisation préféré, le panneau est constitué d'un seul module et d'une couche de béton recouvrant toute la surface de ladite couche d'isolant thermique et entourant entièrement ledit élément de renfort métallique.In a preferred embodiment, 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.

Dans un autre mode de réalisation préféré, le panneau est constitué de deux modules et d'une couche de béton recouvrant toute la surface de chacune des couches d'isolant thermique et entourant entièrement chacun des éléments de renfort métallique.In another preferred embodiment, 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.

Il va bien entendu de soit que l'on pourra ajuster le nombre et la taille des modules en fonction des dimensions et des spécificités techniques de la structure à réaliser.It goes of course of course that we will be able to adjust the number and the size of the modules according to the dimensions and the technical specificities of the structure to be realized.

Le panneau autoportant selon l'invention peut également comprendre les caractéristiques suivantes, prises seules ou en combinaison :

  • l'élément de renfort métallique est un treillis métallique soudé sur les semelles horizontales du profilé métallique en forme de U,
  • le profilé métallique en forme de U est réalisé en acier, éventuellement galvanisé ou émaillé,
  • l'isolant thermique présente, au moins à ses deux extrémités, une épaisseur inférieure à la hauteur du profilé métallique, et la couche de béton est en contact avec les âmes du profilé métallique-.,
The self-supporting panel according to the invention may also comprise the following features, taken alone or in combination:
  • the metal reinforcing element is a wire mesh welded to the horizontal flanges of the U-shaped metal section,
  • the U-shaped metal profile is made of steel, possibly galvanized or enamelled,
  • the thermal insulation has, at least at both ends, a thickness less than the height of the metal section, and the concrete layer is in contact with the webs of the metal profile.

Il est clair que le panneau autoportant selon l'invention pourra être utilisé en position horizontale, verticale ou oblique, pour la réalisation des structures mentionnées ci-dessus.It is clear that the self-supporting panel according to the invention can be used in horizontal position, vertical or oblique, for the realization of structures mentioned above.

Dans le cadre de la présente demande, l'ensemble des caractéristiques d'orientation décrites se réfère à un panneau posé horizontalement sur le sol. Si le panneau était posé verticalement, il faudrait naturellement remplacer les termes horizontaux par verticaux et vice versa dans la description de ce panneau.In the context of the present application, 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.

L'invention va maintenant être décrite de façon plus précise mais non limitative, en regard des figures annexées dans lesquelles :

  • la figure 1 est une vue schématique en coupe d'un premier mode de réalisation d'un panneau autoportant constitué d'un seul module,
  • la figure 2 est une vue schématique en coupe d'un second mode de réalisation d'un panneau autoportant constitué de deux modules,
  • la figure 3 est une représentation partielle de l'assemblage de deux panneaux selon l'invention pour la réalisation d'une structure telle qu'un plancher.
The invention will now be described in a more precise but nonlimiting manner, with reference to the appended figures in which:
  • the figure 1 is a schematic sectional view of a first embodiment of a self-supporting panel consisting of a single module,
  • the figure 2 is a schematic sectional view of a second embodiment of a self-supporting panel consisting of two modules,
  • the figure 3 is a partial representation of the assembly of two panels according to the invention for the realization of a structure such as a floor.

Si l'on se réfère tout d'abord à la figure 1, on peut y voir un panneau autoportant 1 constitué, d'une part d'un module 2 et d'autre part d'une couche de béton 3. Le module 2 comprend un profilé métallique 4 en forme de U qui est ici constitué d'acier galvanisé. Ce profilé 4 est constitué d'une plage centrale 5 sensiblement horizontale et prolongée à ses deux extrémités par des âmes 6 et 6'. Ces âmes 6 et 6' sont elles mêmes prolongées par une semelle sensiblement horizontale 7, respectivement 7'. On voit que la semelle 7 est orientée vers l'intérieur du panneau 1, tandis que la semelle 7' est orientée vers l'extérieur de ce panneau 1.If we first refer to the figure 1 it can be seen 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'. We see that 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 l'intérieur du profilé 4, a été disposé un bloc de laine de roche 8 qui se présente en coupe sous la forme d'un polygone à six côtés et qui a notamment une épaisseur importante dans sa partie centrale, qui diminue en allant vers les bords du bloc. Ce bloc a une épaisseur maximale inférieure à la hauteur du profilé 4.Inside the section 4, was disposed 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.

Au-dessus de ce bloc 8, un treillis métallique 9 a été soudé sur les semelles 7 et 7' du profilé 4. Enfin, une couche de béton 3 a été coulée sur ce module, de telle sorte que le béton vienne en contact avec l'ensemble de la surface de la laine de roche 8, mais aussi avec les âmes 6 et 6', ainsi qu'avec le treillis métallique 9 qui est entièrement immergé dans le béton.Above this block 8, a wire mesh 9 has been welded to the flanges 7 and 7 'of the section 4. Finally, a concrete layer 3 has been poured on this module, so that the concrete comes into contact with the entire surface of the rock wool 8, but also with the souls 6 and 6 ', and with the wire mesh 9 which is fully immersed in the concrete.

Si on se réfère à présent à la figure 2, on peut y voir un second mode de réalisation d'un panneau autoportant 10 selon l'invention, qui est constitué, d'une part de deux modules 11 et 12, et d'autre part d'une couche de béton 13 recouvrant et solidarisant les deux modules 11 et 12.If we now refer to the figure 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.

Les modules 11 et 12 sont identiques au module 2 qui vient d'être décrit pour le premier mode de réalisation.The modules 11 and 12 are identical to the module 2 which has just been described for the first embodiment.

La figure 3 explicite l'assemblage de deux panneaux autoportants 20 et 21 selon l'invention. Chaque panneau 20, 21, comprend un profilé métallique 20', 21' qui comprend des nervures d'emboîtement 20", 21" qui sont de conformation différentes mais complémentaires et permettent, après qu'elles aient été mises en contact, d'éviter tout mouvement respectif des panneaux 20 et 21 dans une direction perpendiculaire à celle du plan des panneaux 20 et 21.The figure 3 explicit assembly of two self-supporting panels 20 and 21 according to the invention. 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.

On munit également le panneau 20 de deux joints 22 et 23 qui permettront d'assurer une étanchéité entre les panneaux 20 et 21, après assemblage.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.

Le panneau selon l'invention présente une résistance améliorée au feu, quelle que soit sa disposition vis-à-vis de la direction de propagation de l'incendie.The panel according to the invention has an improved fire resistance, whatever its disposition with respect to the direction of propagation of the fire.

Ainsi si les flammes se trouvent du côté du profilé métallique, la forme géométrique de ce profilé assure, par l'intermédiaire des âmes, un lien entre la face métallique du panneau et sa face en béton. Ce lien est primordial dans le comportement du système lors d'un incendie. En effet, la face métallique exposée dans ce cas a rapidement plus de résistance, mais peut rester stable pendant plusieurs heures et assurer un rôle d'écran.Thus if the flames are on the side of the metal profile, 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.

Ce lien entre la face en béton et la face métallique est mécaniquement renforcé par l'élément de renfort métallique soudé ou connecté par un autre système aux âmes du profilé et noyé dans l'épaisseur de la couche de béton.This 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.

La laine de roche contenue dans le panneau autoportant est un véritable écran au feu et notamment à l'élévation de température de la face non exposée. N'étant pas directement exposée au feu, sa stabilité mécanique est assurée pendant plusieurs heures.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.

La couche de béton n'étant pas sollicitée à la flamme et peu à l'élévation de température, n'est en rien inquiétée par l'incendie sur l'autre face.The concrete layer not being subjected to the flame and little to the rise in temperature, is not worried by the fire on the other side.

Si la flamme se présente du côté du béton, le fonctionnement est mécaniquement identique au cas précédent, à la différence que l'épaisseur de la couche de béton est suffisante à elle seule, pour résister pendant au moins deux heures. Cette configuration est par conséquent encore plus favorable au bon comportement du panneau exposé à l'incendie.If the flame is on the concrete 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.

La laine de roche assure dans ce cas également la même fonction d'écran thermique et limite considérablement le transfert de température entre la face exposée et celle qui ne l'est pas.In this case, the rockwool also provides the same heat shield function and considerably limits the temperature transfer between the exposed face and the non-exposed one.

Il est important de noter que le panneau selon l'invention se distingue notamment des coffrages de l'art antérieur en ce qu'il est autoportant et peut donc être fabriqué en atelier, puis acheminé facilement sur le chantier ou il pourra être posé immédiatement par assemblage des panneaux préfabriqués.It is important to note that 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.

Outre une grande rapidité de pose, cela permet de garantir des dimensions géométriques constantes pour chaque panneau, d'où la suppression de tout ajustement sur le chantier.In addition to high speed of installation, it ensures constant geometric dimensions for each panel, eliminating any adjustment on the site.

Le panneau selon l'invention présente également l'avantage de pouvoir être utilisé aussi bien pour des façades, que pour des planchers ou des toitures, ce qui permet d'avoir un seul modèle de panneau en stock pour la réalisation de ces structures.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.

Enfin, il est réversible et peut donc être utilisé en fonction des besoins en orientant sa face métallique vers l'intérieur ou l'extérieur du bâtiment, ce qui représente une facilité de mise en oeuvre supplémentaire, tout en accroissant encore sa polyvalence.Finally, it is reversible and can therefore be used as needed by orienting its metal face to the inside or outside of the building, which represents an additional ease of implementation, while further increasing its versatility.
