Description

"Elément d'isolation acoustique destiné à etre posé sur une dalle en béton sous un plancher flottant"
La présente invention concerne un élément d'isolation acoustique destiné à être posé sur une dalle en béton sous un plancher flottant."Acoustic insulation element intended to be placed on a concrete slab under a floating floor"
The present invention relates to an acoustic insulation element intended to be placed on a concrete slab under a floating floor.

Les exigences en matière d'isolation acoustique deviennent de plus en plus strictes, aussi estil souhaitable d'isoler des réalisations particulières comme des planchers flottants par rapport à la dalle en béton qui les supporte. The requirements for sound insulation are becoming more and more stringent, so it is desirable to isolate particular constructions such as floating floors from the concrete slab that supports them.

La présente invention se propose de créer un moyen d'isolation acoustique destiné à améliorer l'isolation acoustique entre un plancher flottant et une dalle en béton. The present invention proposes to create a means of sound insulation intended to improve the sound insulation between a floating floor and a concrete slab.

Selon l'invention, ce moyen est un élément d'isolation en forme de bande caractérisé en ce qu'il se compose d'une nappe en fibres non tissées, - d'une feuille d'étanchéité fixée sur l'une des faces de la nappe non tissée par aiguilletage. According to the invention, this means is a strip-shaped insulating element characterized in that it consists of a sheet of nonwoven fibers, - of a sealing sheet fixed to one of the faces of the nonwoven tablecloth by needling.

La mise en place d'un tel élément d'isolation acoustique sur la dalle en béton ne pose aucun problème. Cette nappe permet en outre d'absorber les éventuelles irrégularités de la dalle en béton. Cet élément d'isolation acoustique assure en outre une séparation étanche entre la surface de la dalle en béton et le plancher flottant. Cette isolation évite notamment la remontée de l'humidité lorsque la dalle en béton est la dalle de la cave ; cela évite également la remontée de la poussière jusque sous et à travers le plancher flottant. Cela est d'autant plus intéressant que dans certains-cas le plancher flottant reçoit un revêtement de type moquette car dans ce cas les traces des lames apparaissent à la longue sous la forme de dépôts de poussières. The installation of such an acoustic insulation element on the concrete slab poses no problem. This layer also makes it possible to absorb any irregularities in the concrete slab. This sound insulation element also provides a sealed separation between the surface of the concrete slab and the floating floor. This insulation notably prevents the rise of humidity when the concrete slab is the cellar slab; this also prevents the dust from rising up under and through the floating floor. This is all the more interesting in that in some cases the floating floor receives a carpet-like coating because in this case the traces of the blades appear in the long run in the form of dust deposits.

Selon la séparation à réaliser, la nappe étanche est placée sur la dalle en béton, c'est-à-dire en-dessous de la nappe non tissée. Une mise en place inverse est également envisageable. Depending on the separation to be carried out, the waterproof sheet is placed on the concrete slab, that is to say below the nonwoven sheet. A reverse installation is also possible.

Pour parfaire la séparation réalisée par la feuille d'étanchéité, au niveau de la jonction bord à bord de deux nappes de fibres non tissées, il est intéressant que cette feuille d'étanchéité présente un certain débord, sur l'un de ses côtés pour recouvrir la feuille d'étanchéité et la nappe de fibres non tissées de l'élément adjacent. To perfect the separation produced by the sealing sheet, at the edge-to-edge junction of two sheets of nonwoven fibers, it is advantageous that this sealing sheet has a certain overhang, on one of its sides to cover the sealing sheet and the nonwoven fiber web with the adjacent element.

Il est à remarquer que suivant le mode de pose choisi, c'est-à-dire la feuille d'étanchéité audessus ou en-dessous, on mettra en place d'abord une feuille sans débord ou dont le débord a été coupé puis la seconde feuille ou bande avec son débord venant coiffer la feuille d'étanchéité de la bande déjà mise en place. It should be noted that depending on the installation method chosen, that is to say the waterproofing sheet above or below, we will first put in place a sheet without overhang or whose overhang has been cut and then the second sheet or strip with its overhang covering the sealing sheet of the strip already in place.

Dans l'autre cas, on met en place l'élément d'isolation acoustique avec le débord de la feuille d'étanchéité du côté du bord recevant l'élément d'isolation acoustique suivant et ainsi de suite. In the other case, the sound insulation element is put in place with the overhang of the sealing sheet on the side of the edge receiving the next sound insulation element and so on.

Dans le premier cas, le joint peut également être scellé par un ruban adhésif placé par-dessus le débord. In the first case, the joint can also be sealed by an adhesive tape placed over the overhang.

La présente invention sera décrite ci-après de manière plus détaillée à l'aide des dessins annexés dans lesquels
- la figure 1 est une vue schématique en coupe d'un élément d'isolation acoustique selon l'invent ion.The present invention will be described below in more detail with the aid of the accompanying drawings in which
- Figure 1 is a schematic sectional view of an acoustic insulation element according to the invention.

- la figure 2 montre la jonction de deux éléments d'isolation acoustique selon l'invention, correspondant à un premier mode de pose. - Figure 2 shows the junction of two acoustic insulation elements according to the invention, corresponding to a first method of installation.

- la figure 3 est une vue analogue à celle de la figure 2 correspondant à un second mode de pose. - Figure 3 is a view similar to that of Figure 2 corresponding to a second installation method.

Selon la figure 1, l'élément d'isolation acoustique qui se présente de préférence sous la forme d'une bande fournie en rouleau, et qui est destiné à êtreposé sur une dalle en béton, par exemple sous un plancher flottant, se compose d'une nappe 1 en fibres non tissées (feutre) et d'une feuille d'étanchéité 2. According to Figure 1, the sound insulation element which is preferably in the form of a strip supplied in a roll, and which is intended to be placed on a concrete slab, for example under a floating floor, consists of: '' a sheet 1 of non-woven fibers (felt) and a sealing sheet 2.

Cette feuille est fixée à la fibre 1 par aiguilletage.This sheet is attached to fiber 1 by needling.

Cela est schématisé par les fils 3 qui sont entraînées de la nappe en fibres non tissées 1 à travers la feuille d'étanchéité lors du retour des aiguilles assurant l'aiguilletage.This is shown schematically by the threads 3 which are entrained from the nonwoven fiber web 1 through the sealing sheet when the needles ensuring needling return.

Si la figure 1 est une coupe transversale de l'élément dtisolation acoustique selon l'invention, l'un des côtés 4 est droit, c'est-à-dire que la nappe non tissée 1 et la feuille d'étanchéité 2 s'arrêtent à la même hauteur. Par contre, l'autre côté 5 présente un débord 6, c'est-à-dire que le bord 7 de la nappe de fibres non tissées est en retrait du bord de la feuille d'étanchéité d'une distance d correspondant au chevauchement souhaité au moment de la pose. If FIG. 1 is a cross section of the sound insulation element according to the invention, one of the sides 4 is straight, that is to say that the nonwoven ply 1 and the sealing sheet 2 s' stop at the same height. On the other hand, the other side 5 has an overhang 6, that is to say that the edge 7 of the sheet of nonwoven fibers is set back from the edge of the sealing sheet by a distance d corresponding to the overlap. desired at the time of installation.

Les figures 2 et 3 montrent deux modes de pose possibles d'élément d'isolation acoustique selon l'invention. Dans le premier cas représenté à la figure 2, sur une dalle 10 on place un premier élément d'étanchéité 11 tel que celui de la figure 1, avec sa feuille d'étanchéité 2 située en bas, contre la surface 12 de la dalle. Figures 2 and 3 show two possible installation methods of acoustic insulation element according to the invention. In the first case shown in FIG. 2, a first sealing element 11 such as that of FIG. 1 is placed on a slab 10, with its sealing sheet 2 located at the bottom, against the surface 12 of the slab.

Le second élément d'isolation acoustique 13 est placé par-dessus le débord 6 de manière à assurer l'isolation. Les deux feuilles d'étanchéité 2 des éléments 11 et 13 peuvent par exemple être collées au niveau de leur réunion. The second acoustic insulation element 13 is placed over the overhang 6 so as to provide insulation. The two sealing sheets 2 of the elements 11 and 13 can for example be glued at their meeting.

Ce mode de pose est intéressant pour arrêter par exemple l'humidité que pourrait laisser passer ou dégager la dalle 10. This installation method is useful for stopping, for example, the humidity that slab 10 could allow or pass through.

Le seconde mode de pose représenté à la figure 3 procède de manière inverse. On place d'abord l'élément 14 avec son côté 4 ne comportant pas de débord. Puis on place un second élément d'isolation acoustique 15 de façon que le débord 6 de sa feuille d'étanchéité 2 coiffe le côté du bord 4 de l'élément d'isolation acoustique 14 déjà mis en place. The second installation method shown in Figure 3 proceeds in reverse. First place the element 14 with its side 4 having no projection. Then a second acoustic insulation element 15 is placed so that the overhang 6 of its sealing sheet 2 covers the side of the edge 4 of the acoustic insulation element 14 already in place.

Ce mode de pose est intéressant par exemple en cas de risque d'arrivée d'humidité, on place la feuille d'étanchéité directement en contact avec la dalle pour avoir une certaine protection de la nappe de fibres. This installation method is advantageous, for example, when there is a risk of moisture entering, the sealing sheet is placed directly in contact with the slab to have a certain protection of the sheet of fibers.

Les éléments d'isolation acoustique selon l'invention peuvent être fabriqués en bande continu et être livrés pour la pose en rouleaux. I1 peut également s'agir de plaques de grandes dimensions qui sont posées à la manière de dalles de moquette. Quelle que soit la présentation du produit, les deux modes de pose représentés aux figures 2 et 3 sont envisageables.  The acoustic insulation elements according to the invention can be manufactured in a continuous strip and delivered for installation in rolls. They can also be large sheets which are laid in the manner of carpet tiles. Whatever the presentation of the product, the two installation methods shown in Figures 2 and 3 are possible.
