Description

L'invention concerne un dispositif de couverture de bâtiment comprenant un support en tôle nervurée, un pare-vapeur comportant une couche imperméable à la vapeur d'eau, un matelas thermiquement isolant et une membrane d'étanchéité, mutuellement superposés dans cet ordre, la membrane d'étanchéité recouvrant les extrémités supérieures d'organes d'assemblage qui traversent les autres constituants précités du dispositif.The invention relates to a building cover device comprising a ribbed sheet metal support, a vapor barrier having a layer impervious to water vapor, a thermally insulating mat and a waterproofing membrane, mutually superimposed in that order, the waterproofing membrane covering the upper ends of organs assembly which pass through the other constituents mentioned above of the device.

De tels dispositifs sont bien connus (voir par exemple FR 2 635 603 A) et sont définis par exemple dans la norme française NF P 84-206. On connaít en particulier des dispositifs dans lesquels la couche imperméable du pare-vapeur est une feuille mince d'aluminium, qui est collée, pour assurer sa tenue mécanique et permettre sa manipulation, sur un voile de verre d'une masse surfacique d'environ 40 g/m2. Le pare-vapeur ne confère au dispositif aucune propriété d'absorption acoustique. On connaít également un dispositif dans lequel le pare-vapeur comporte une couche poreuse épaisse lui conférant des propriétés d'absorption acoustique. Cette couche poreuse épaisse tend à s'écraser lorsqu'une personne marche sur le dispositif, notamment lors de la mise en place de celui-ci, ce qui entraíne l'inconvénient suivant. Les constituants du dispositif sont généralement assemblés entre eux au moyen de vis qui les traversent. Pour assurer la continuité de l'étanchéité, au moins une partie de l'épaisseur de la membrane recouvre la tête de la vis. Si une personne marche au voisinage d'une vis et que la couche poreuse du pare-vapeur s'écrase à cet endroit, il en résulte un affaissement des couches susjacentes et la vis traverse la seconde couche de la membrane d'étanchéité, détruisant l'étanchéité de la toiture.Such devices are well known (see for example FR 2 635 603 A) and are defined for example in the French standard NF P 84-206. In particular, devices are known in which the impervious layer of the vapor barrier is a thin sheet of aluminum, which is glued, to ensure its mechanical strength and allow its handling, on a glass veil with a mass per unit area of 40 g / m 2 . The vapor barrier does not give the device any sound absorption property. There is also known a device in which the vapor barrier comprises a thick porous layer conferring acoustic absorption properties. This thick porous layer tends to crash when a person walks on the device, especially when setting it, which causes the following disadvantage. The constituents of the device are generally assembled together by means of screws passing through them. To ensure the continuity of the seal, at least a portion of the thickness of the membrane covers the head of the screw. If a person walks in the vicinity of a screw and the porous layer of the vapor barrier crushes at this point, the overlying layers collapse and the screw passes through the second layer of the waterproofing membrane, destroying the waterproofing of the roof.

On a découvert qu'il était possible d'éliminer cet inconvénient, tout en conférant au dispositif de couverture des propriétés d'absorption acoustique. It has been discovered that it is possible to eliminate this disadvantage, while giving the cover sound absorption properties.

L'invention vise notamment un dispositif du genre défini en introduction, et prévoit que le pare-vapeur comporte en outre une couche à porosité ouverte d'une masse surfacique d'au moins 240 g/m2, conférant au dispositif des propriétés d'absorption acoustique et ne s'écrasant pratiquement pas lorsqu'une personne marche sur celui-ci.The invention aims in particular at a device of the type defined in the introduction, and provides that the vapor barrier further comprises an open porosity layer with a mass per unit area of at least 240 g / m 2 , giving the device properties of sound absorption and hardly crashing when someone walks on it.

Le terme "pare-vapeur" désigne ici l'ensemble des couches interposées entre le support nervuré et le matelas thermiquement isolant, qui est de préférence un sous-ensemble préconstitué, mais qui peut le cas échéant être composé de couches appliquées indépendamment.The term "vapor barrier" refers here to all the layers interposed between the ribbed support and the heat mattress insulator, which is preferably a preconstituted subset, but which can if necessary be composed of layers applied independently.

Les caractéristiques et avantages de l'invention seront exposés plus en détail dans la description ci-après, en se référant aux dessins annexés, sur lesquels:

  • la figure 1 est une vue partielle en perspective éclatée d'un dispositif de couverture selon l'invention;
  • la figure 2 est une vue partielle en coupe transversale du dispositif; et
  • les figures 3 et 4 sont des graphiques relatifs aux propriétés d'absorption acoustique de deux dispositifs de couverture selon l'invention.
The features and advantages of the invention will be described in more detail in the description below, with reference to the appended drawings, in which:
  • Figure 1 is a partial exploded perspective view of a cover device according to the invention;
  • Figure 2 is a partial cross-sectional view of the device; and
  • Figures 3 and 4 are graphs relating to the sound absorption properties of two cover devices according to the invention.

Les figures 1 et 2 montrent la structure connue d'un dispositif de couverture de bâtiment. Ce dispositif comprend un support 1 en tôle d'acier nervurée perforée, formant des gouttières 2 de profil trapézoïdal, ouvertes vers le haut, s'étendant parallèlement les unes aux autres. Les bords de deux gouttières voisines sont reliés entre eux par une bande de matière 3, les différentes bandes 3 s'étendant dans un même plan. Le support 1 est percé d'une multitude de trous 4 d'un rayon de 5 mm disposés avec un entraxe mutuel de 12,5 mm. Le taux de perforation du support est de 22 %.Figures 1 and 2 show the known structure of a device of building cover. This device includes a support 1 perforated ribbed steel sheet, forming gutters 2 trapezoidal profile, open up, extending parallel to each other. The edges of two adjacent gutters are connected to each other by a band of material 3, the different strips 3 extending in a same plan. The support 1 is pierced with a multitude of holes 4 with a radius of 5 mm arranged with a mutual spacing of 12.5 mm. The perforation rate of the support is 22%.

Chaque gouttière 2 est remplie d'un bloc profilé 5 ayant une section transversale trapézoïdale correspondante, par exemple formé de laine minérale et entouré d'une feuille imperméable. Cette dernière peut être en polyéthylène de haute densité et sert à éviter l'émission de poussière. Les blocs 5 jouent le rôle d'absorbant thermique et/ou acoustique. Each gutter 2 is filled with a profiled block 5 having a corresponding trapezoidal cross-section, for example formed of mineral wool and surrounded by an impermeable sheet. The latter can be made of high density polyethylene and serves to prevent the emission of dust. Blocks 5 play the role of heat absorbent and / or acoustic.

La surface plane sensiblement continue définie par les bandes 3 et la face supérieure des blocs 5 est recouverte d'un pare-vapeur 6 qui sera décrit plus loin, sur lequel repose un matelas d'isolation thermique 7 par exemple à base de laine minérale.The substantially continuous flat surface defined by the strips 3 and the upper face of the blocks 5 is covered a vapor barrier 6 which will be described later, on which rests a thermal insulation mat 7 for example based of mineral wool.

La figure 1 montre également deux couches 8 et 9 d'une membrane d'étanchéité, collées l'une sur l'autre, ainsi que la tête plate 10 d'une vis servant à l'assemblage mutuel des constituants du dispositif. La couche inférieure 8 peut être traversée par la tige de la vis, la tête 10 de celle-ci l'appliquant sur la face supérieure du matelas isolant 7. La continuité de l'étanchéité de la membrane est alors assurée par la couche 9. En variante, La couche 8 peut recouvrir la tête de la vis et être collée sur le matelas 7.Figure 1 also shows two layers 8 and 9 of a membrane, glued together, as well as the flat head 10 of a screw serving for the mutual assembly of constituents of the device. The lower layer 8 can be crossed by the rod of the screw, the head 10 thereof applying it on the upper face of the insulation blanket 7. The continuity of the waterproofness of the membrane is then ensured by way of the layer 9. In a variant, the layer 8 may cover the head of the screw and be glued on the mattress 7.

De manière connue également, le pare-vapeur 6 comprend une couche supérieure imperméable 6a (figure 2) constituée par une feuille d'aluminium.In a manner also known, the vapor barrier 6 comprises a waterproof upper layer 6a (FIG. an aluminum foil.

Selon l'invention, la feuille 6a est collée sur une couche poreuse 6b constituée par un voile de fibres de verre d'une masse surfacique d'au moins 240 g/m2. Le cas échéant, la couche 6b peut être obtenue en superposant plusieurs nappes totalisant une masse surfacique d'au moins 240 g/m2.According to the invention, the sheet 6a is bonded to a porous layer 6b constituted by a fiberglass web having a basis weight of at least 240 g / m 2 . If necessary, the layer 6b can be obtained by superimposing several layers totaling a mass per unit area of at least 240 g / m 2 .

La figure 3 montre la variation du coefficient d'absorption acoustique αS, mesuré selon la norme française NF EN 20354, en fonction de la fréquence médiane f en hertz. Les mesures ont été effectuées sur un dispositif selon les figures 1 et 2, le matelas isolant étant réalisé en laine de roche et présentant une épaisseur de 60 mm et une masse volumique de 160 kg/m3, et la membrane d'étanchéité étant composée de deux couches de bitume ayant chacune une épaisseur de 3,5 mm et une masse surfacique de 8,8 kg/m2.FIG. 3 shows the variation of the acoustic absorption coefficient α S , measured according to the French standard NF EN 20354, as a function of the median frequency f in hertz. The measurements were carried out on a device according to FIGS. 1 and 2, the insulation blanket being made of rock wool and having a thickness of 60 mm and a density of 160 kg / m 3 , and the sealing membrane being composed of two layers of bitumen each having a thickness of 3.5 mm and a basis weight of 8.8 kg / m 2 .

La figure 4 est analogue à la figure 3, et relative à un dispositif de couverture dans lequel les blocs 5 ont été omis. FIG. 4 is similar to FIG. 3, and relating to a cover device in which the blocks 5 have been omitted.

Le coefficient αW a également été déterminé selon le projet de norme internationale ISO/DIS 11654. Ce coefficient est égal à 0,85 avec les blocs 5 et 0,70 en l'absence de ceux-ci.The coefficient α W has also been determined according to draft international standard ISO / DIS 11654. This coefficient is equal to 0.85 with blocks 5 and 0.70 in the absence of these.

On constate que l'invention fournit de bonnes caractéristiques d'absorption acoustique, surtout lorsque les blocs 5 sont présents, mais également lorsqu'ils sont omis.It is found that the invention provides good characteristics sound absorption, especially when the blocks 5 are present, but also when they are omitted.
