Description

La présente invention concerne des poutrelles destinées à la fabrication d'un plancher isolant et comportant une armature métallique en treillis et un talon dans lequel est noyée la partie inférieure de l'armature.The present invention relates to beams intended for the manufacture of an insulating floor and comprising a metallic lattice reinforcement and a heel in which the lower part of the reinforcement is embedded.

Les impératifs d'économie d'énergie et la réglementation imposent d'isoler thermiquement les planchers. La solution consistant à rapporter un isolant en sous-face du plancher n'est pas facile à réaliser techniquement et de façon économique.Energy saving requirements and regulations require thermally insulating floors. The solution consisting in adding an insulator to the underside of the floor is not easy to carry out technically and economically.

Il a été proposé dans le brevet FR 78 31 719 au nom du demandeur de réaliser des poutrelles du type treillis avec un talon logé dans un élément isolant ayant servi de coffrage pour couler le béton du talon. L'utilisation de ces poutrelles permet, en combinaison avec des entrevous isolants, d'obtenir directement une sous-face isolante pour le plancher.It was proposed in patent FR 78 31 719 in the name of the applicant to produce truss type beams with a heel housed in an insulating element having served as formwork for pouring concrete from the heel. The use of these beams allows, in combination with insulating interjoists, to directly obtain an insulating underside for the floor.

L'invention a pour but de fournir des poutrelles permettant aussi de réaliser directement des planchers avec une sous-face isolante, tout en simplifiant au maximum la fabrication et la manipulation des poutrelles.The object of the invention is to provide beams also making it possible to directly produce floors with an insulating underside, while simplifying the manufacture and handling of the beams as much as possible.

Ce but est atteint par une poutrelle du type défini en tête de la description, dans laquelle, conformément à l'invention, le talon est essentiellement en béton isolant léger, la tenue mécanique de la poutrelle étant assurée par l'armature.This object is achieved by a beam of the type defined at the head of the description, in which, in accordance with the invention, the heel is essentially made of light insulating concrete, the mechanical strength of the beam being ensured by the frame.

L'utilisation du béton isolant léger pour former le talon des poutrelles apporte de très nombreux avantages par rapport aux poutrelles à talon en béton classique logé dans un élément isolant.The use of light insulating concrete to form the heel of the beams brings very many advantages compared to the heel beams of conventional concrete housed in an insulating element.

D'abord, l'isolation thermique est facile à réaliser et à contrôler puisqu'elle dépend essentiellement de l'épaisseur et de la masse volumique du béton isolant léger utilisé. Ensuite, le poids des poutrelles est considérablement réduit -une division du poids par deux, voire par trois, est possible-, ce qui facilite grandement la manipulation sur chantier. De plus, le béton isolant léger apporte une protection de l'armature vis à vis de la corrosion et fait bénéficier la poutrelle de sa bonne tenue au feu. Par ailleurs, l'étayage est possible directement sous la poutrelle, ce qui est plus délicat lorsqu'un isolant est rapporté en sous-face, et la face inférieure du talon peut être plâtrée directement, ce qui n'est pas le cas de la plupart des isolants.First, thermal insulation is easy to perform and control since it depends essentially on the thickness and density of the light insulating concrete used. Then, the weight of the beams is considerably reduced - a division of the weight by two, even by three, is possible -, which greatly facilitates handling on site. In addition, the light insulating concrete provides protection of the reinforcement against the corrosion and makes the beam benefit from its good fire resistance. In addition, shoring is possible directly under the beam, which is more delicate when an insulator is attached on the underside, and the underside of the heel can be plastered directly, which is not the case with the most insulators.

Le béton isolant léger est, comme connu en soi, réalisé avec un mélange comportant un liant hydraulique (ciment), des particules de polymère expansé (par exemple des billes de polystyrène) et de l'eau.Light insulating concrete is, as known per se, produced with a mixture comprising a hydraulic binder (cement), particles of expanded polymer (for example polystyrene beads) and water.

Pour assurer une bonne portée sur les appuis, il est possible de réaliser les extrémités du talon en un matériau plus résistant que le béton isolant léger, par exemple en béton classique. De la sorte, on réalise également une protection du béton isolant léger lors des manutentions et du transport.To ensure a good bearing on the supports, it is possible to make the ends of the heel in a more resistant material than light insulating concrete, for example in conventional concrete. In this way, a light insulating concrete protection is also produced during handling and transport.

Un mode particulier de réalisation de l'invention est décrit ci-après, à titre indicatif mais non limitatif, en référence aux dessins annexés sur lesquels :

  • - la figure 1 est une vue en coupe transversale d'une partie de plancher isolant comprenant des poutrelles conformes à l'invention, et
  • - la figure 2 est une vue en coupe longitudinale d'une poutrelle du plancher de la figure 1.
A particular embodiment of the invention is described below, by way of indication but not limitation, with reference to the appended drawings in which:
  • FIG. 1 is a cross-sectional view of a part of the insulating floor comprising beams according to the invention, and
  • - Figure 2 is a longitudinal sectional view of a beam of the floor of Figure 1.

Comme le montrent les figures 1 et 2, les poutrelles 10 conformes à l'invention sont du type treillis avec une armature métallique 11, par exemple triangulée, dont la partie inférieure est noyée dans un talon 12 en béton isolant léger. Les poutrelles sont préfabriquées en usine de la même façon que les poutrelles de type treillis usuelles munies d'un talon en béton classique, le béton classique étant remplacé par un béton isolant léger dont l'épaisseur e peut être plus importante. Pour la détermination de la résistance mécanique de la poutrelle, seule la section d'acier tendue de l'armature intervient dans le calcul, le béton isolant léger n'étant pas pris en compte.As shown in Figures 1 and 2, the beams 10 according to the invention are of the lattice type with a metal frame 11, for example triangulated, the lower part of which is embedded in a heel 12 of light insulating concrete. The beams are prefabricated in the factory in the same way as the usual truss type beams provided with a conventional concrete heel, the conventional concrete being replaced by a light insulating concrete whose thickness e may be greater. For the determination of the mechanical resistance of the beam, only the tensed steel section of the reinforcement is involved in the calculation, the light insulating concrete not being taken into account.

Les extrémités 13, 14 de la poutrelle destinées à venir en portée sur les appuis sont réalisés par exemple en béton classique, la liaison entre celui-ci et le béton isolant léger ne posant aucun problème (figure 2).The ends 13, 14 of the beam intended to come carried on the supports are made for example of concrete classic, the connection between it and the light insulating concrete poses no problem (Figure 2).

Pour la réalisation d'un plancher isolant, les intervalles entre poutrelles sont comblés par des entrevous isolants 15, par exemple réalisés eux aussi en béton isolant léger (figure 1). Ensuite, de façon classique, une dalle, dite de compression est coulée sur les poutrelles 10 et entrevous 15, pour reprendre les efforts de compression, alors que les efforts de traction sont repris par les armatures des poutrelles. On obtient ainsi directement un plancher isolé en sous-face.For the production of an insulating floor, the intervals between beams are filled with insulating interjoists 15, for example also made of light insulating concrete (Figure 1). Then, conventionally, a so-called compression slab is poured onto the beams 10 and interjoists 15, to take up the compression forces, while the tensile forces are taken up by the reinforcements of the beams. This gives an insulated floor directly on the underside.

De préférence, le béton isolant léger du talon 12 est à base de billes de polystyrène expansé mélangé à un liant hydraulique et de l'eau. Il est ainsi possible de réaliser un béton isolant léger dont la masse volumique peut descendre jusqu'à 2 kg/m3.Preferably, the light insulating concrete of the heel 12 is based on expanded polystyrene balls mixed with a hydraulic binder and water. It is thus possible to produce a light insulating concrete whose density can drop to 2 kg / m3.

A titre indicatif, une poutrelle conforme à l'invention a été réalisée de la façon suivante.As an indication, a beam according to the invention was produced in the following manner.

Deux pièces d'extrémité 13, 14, par exemple des tronçons de talon en béton de granulats courant, sont positionnées entre deux profilés métalliques formant les joues latérales du coffrage dans lequel le béton isolant léger doit être coulé. Les pièces 13, 14 forment les parois d'extrémité du coffrage. Le béton isolant léger utilisé est de consistance liquide à base de billes de polystyrène expansé de masse volumique 3 kg/m3. Une armature classique de type treillis est positionnée après coulage du béton isolant léger. Les pièces d'extrémité 13, 14 présentent des rainures formées dans leur face supérieure pour recevoir les profilés inférieurs de l'armature métallique. Ainsi, ces pièces d'extrémité ont trois fonctions : coffrage perdu permettant le dimensionnement en longueur de la poutrelle, cales d'armature et transmission des efforts de compression lors de l'utilisation de la poutrelle.Two end pieces 13, 14, for example heel sections made of common aggregate concrete, are positioned between two metal sections forming the lateral cheeks of the formwork in which the light insulating concrete is to be poured. The parts 13, 14 form the end walls of the formwork. The light insulating concrete used is of liquid consistency based on expanded polystyrene beads with a density of 3 kg / m3. A conventional truss type reinforcement is positioned after pouring the light insulating concrete. The end pieces 13, 14 have grooves formed in their upper face to receive the lower sections of the metal frame. Thus, these end pieces have three functions: lost formwork allowing the dimensioning in length of the beam, reinforcing shims and transmission of the compression forces during the use of the beam.

Les essais réalisés sur une poutrelle seule ou sur plancher démontrent un mode de comportement identique aux poutrelles classiques avec une flexibilité légèrement supérieure pour une section d'acier équivalente.Tests carried out on a single beam or on a floor demonstrate a mode of behavior identical to conventional beams with slightly greater flexibility for an equivalent steel section.
