Abstract

The acoustic construction panel for floor slabs or walls is a sandwich of two rigid layers with a resilient layer (2) between. Both outside layers are made of concrete or other rigid material. The thicker layer (1) is precast with slots (5) on its inside face leading to rounded grooves (4).The thinner layer (3) may be precast or in situ concrete and plain. The rounded grooves comprise a Helmholtz resonator for audible frequencies. The slots are narrow enough not to compromise the resonator function of the grooves and increase the air gap between the rigid layers.

Description

L'invention concerne une paroi présentant d'excellentes propriétés d'isolation acoustique et ses applications comme dalle de plancher ou comme mur. The invention relates to a wall with excellent sound insulation properties and its applications as a floor slab or as a wall.

La paroi de rinvention comporte deux couches rigides séparées par une couche résiliente, l'une au moins des couches rigides comportant des alvéoles filants, aptes à constituer un résonateur d'Helmoltz pour les fréquences audibles, ces alvéoles communiquant avec la couche résiliente par de multiples passages sufflsamment étroits pour ne pas compromettre la fonction résonateur des alvéoles et coopérant avec les alvéoles pour augmenter localement l'intervalle d'air entre les matériaux des deux couches rigides. The inventive wall comprises two rigid layers separated by a resilient layer, at least one of the rigid layers comprising threaded cells, capable of constituting a Helmoltz resonator for the audible frequencies, these cells communicating with the resilient layer by multiple passages which are sufficiently narrow so as not to compromise the resonator function of the cells and which cooperate with the cells to locally increase the air gap between the materials of the two rigid layers.

Par l'expression "couche résiliente", on désigne une couche ayant la même raideur dynamique qu'une nappe fibreuse qui serait soumise à des vibrations ou chocs transversaux. The expression "resilient layer" denotes a layer having the same dynamic stiffness as a fibrous sheet which would be subjected to vibrations or transverse shocks.

Les passages sont de préférence rectilignes. The passages are preferably straight.

Dans une application typique, l'une des couches rigides est constituée par une dalle préfabriquée en matériau homogène, relativement épaisse, et comporte lesdits alvéoles tandis que l'autre couche est une dalle pleine relativement mince coulée in-situ ou préfabriquée. In a typical application, one of the rigid layers is constituted by a prefabricated slab of homogeneous material, relatively thick, and comprises said cells while the other layer is a relatively thin solid slab cast in situ or prefabricated.

La paroi est destinée à être utilisée horizontalement comme une structure de plancher ou verticalement comme une structure de cloison ou de mur. The wall is intended to be used horizontally as a floor structure or vertically as a partition or wall structure.

De façon en soi connue, la dalle épaisse et la chape mince peuvent être réalisées en béton mais le choix de ce matériau n'est pas limitatif. In known manner, the thick slab and the thin screed can be made of concrete but the choice of this material is not limiting.

Dans le cas d'une cloison, par exemple, il est aussi prévu d'utiliser le plate ou la terre cuite comme matériau des couches rigides. In the case of a partition, for example, it is also planned to use the flat or terracotta as material for rigid layers.

La couche intermédiaire est par exemple un matelas de laine minérale, de façon en soi connue. The intermediate layer is for example a mattress of mineral wool, in a manner known per se.

Le matériau des couches rigides est de préférence non poreux mais un matériau poreux peut convenir selon les cas. The material of the rigid layers is preferably non-porous, but a porous material may be suitable depending on the case.

Les flgures du dessin joint illustrent un exemple de structure conforme à l'invention: - la fig. 1 est une perspective partielle de la dalle alvéolée; - la fig. 2 est une coupe longitudinale de la structure selon raxe d'un alvéole; - la fig. 3 est une coupe transversale de la structure; - et la fig. 4 est une coupe montrant une variante d'alvéole. The figures in the accompanying drawing illustrate an example of a structure in accordance with the invention: FIG. 1 is a partial perspective of the honeycomb slab; - fig. 2 is a longitudinal section of the structure along the axis of a cell; - fig. 3 is a cross section of the structure; - and fig. 4 is a section showing a variant of a cell.

La structure représentée est une structure de plancher constituée d'une dalle épaisse 1 en béton, d'un matelas préfabriqué de fibres minérales 2 (laine de verre ou laine de roche) appliqué sur la dalle et d'une chape flottante 3 en béton coulée in-situ sur le matelas. The structure shown is a floor structure consisting of a thick concrete slab 1, a prefabricated mattress of mineral fibers 2 (glass wool or rock wool) applied to the slab and a floating screed 3 in poured concrete in situ on the mattress.

Les dimensions du complexe sont typiquement: - longueur : 2,5 à 15 m, - largeur : inférieure à 2,50 m, - épaisseur : 15 à 60 cm
Les épaisseurs des différentes couches sont: - dalle alvéolée : 8 à 50 cm, - matelas résilient : 2 à 10 cm - chape flottante : 2 à 12 cm
Cette dalle est destinée à reposer sur des appuis (poteaux ou murs) de façon en soi connue.The dimensions of the complex are typically: - length: 2.5 to 15 m, - width: less than 2.50 m, - thickness: 15 to 60 cm
The thicknesses of the different layers are: - honeycomb slab: 8 to 50 cm, - resilient mattress: 2 to 10 cm - floating screed: 2 to 12 cm
This slab is intended to rest on supports (posts or walls) in a manner known per se.

Conformément à rinvention, la dalle épaisse 1 comporte des alvéoles tubulaires 4 filants selon la longueur de la dalle et dont la section représente environ 20 à 60 % de la section totale de la dalle 1, et des fentes 5 de largeur 1 à 4cm, et de 10 à 60 cm de longueur, espacées de 10 à 60 cm, qui font communiquer les alvéoles avec la face de la dalle qui est au contact du matelas de fibres. Les fentes s'étendent parallèlement à la longueur de la dalle. In accordance with the invention, the thick slab 1 comprises tubular cells 4 threading along the length of the slab and whose section represents approximately 20 to 60% of the total section of the slab 1, and slots 5 of width 1 to 4 cm, and 10 to 60 cm in length, spaced 10 to 60 cm apart, which make the cells communicate with the face of the slab which is in contact with the fiber mat. The slots extend parallel to the length of the slab.

Les alvéoles ont toute forme voulue. Par exemple, ils ont une section droite de forme circulaire ou ovale. Les figs. 3 et 4 montrent pour l'exemple deux formes d'alvéoles. The cells have any desired shape. For example, they have a cross section of circular or oval shape. Figs. 3 and 4 show for the example two forms of cells.

Les fentes de deux files voisines sont disposées en vis à vis ou sont décalées. The slots of two neighboring lines are arranged opposite or are offset.

En variante, les fentes sont remplacées par des passages tubulaires de diamètre 2 à 4 cm espacés de 5 à 30 cm. As a variant, the slots are replaced by tubular passages with a diameter of 2 to 4 cm spaced from 5 to 30 cm.

La structure se comporte, du point de vue acoustique, comme un complexe masse-ressort-masse qui constitue un bon isolant acoustique contre la transmission des bruits aériens et la transmission des bruits d'impacts. The structure behaves, from an acoustic point of view, like a mass-spring-mass complex which constitutes a good acoustic insulator against the transmission of airborne noises and the transmission of impact noises.

La paroi de Invention peut comporter, selon les cas, des revêtements solidaires ou simplement attenants, de façon en soi connue.  The wall of the invention may include, depending on the case, solid or simply adjoining coatings, in a manner known per se.
