Description

Procédé pour réaliser un tapis antivibratoire Method for making an anti-vibration mat

La présente invention concerne les procédés pour réaliser des tapis antivibratoires qui trouvent une application particulièrement avantageuse dans le domaine de l'isolation, par exemple des dalles flottantes, fondations ou analogues des bâtiments industriels, d'habitation ou analogues, contre les vibrations qui se produisent notamment au niveau des voies ferrées, des machines outils, etc. II est déjà connu des tapis antivibratoires mais la structure de ces tapis ne permet pas de réaliser de très grandes surfaces d'isolation, par exemple pour l'isolation des voies ferrées, des bâtiments industriels, etc.The present invention relates to methods for producing anti-vibration mats which find a particularly advantageous application in the field of insulation, for example floating slabs, foundations or the like of industrial, residential or similar buildings, against the vibrations which occur. especially on railways, machine tools, etc. Anti-vibration mats are already known, but the structure of these mats does not allow very large insulation surfaces to be produced, for example for the insulation of railway tracks, industrial buildings, etc.

Aussi, la présente invention a-t-elle pour but de mettre en oeuvre un procédé pour réaliser un tapis antivibratoire qui pallie les inconvénients mentionnés ci-dessus, en permettant de réaliser, à un prix de revient très faible, de grandes surfaces d'isolation contre tout type de vibrations et en contribuant en plus à la sauvegarde de l'environnement. Plus précisément, la présente invention a pour objet un procédé pour réaliser un tapis antivibratoire, caractérisé par le fait qu'il consiste à réaliser une première couche d'un premier matériau visco-élastique, à réaliser un premier ensemble de rainures sur une face de cette première couche, à réaliser une seconde couche d'un second matériau visco- élastique, à réaliser un second ensemble de rainures sur une face de cette seconde couche, à superposer les deux dites première et seconde couches l'une sur l'autre de façon que le premier ensemble de rainures soit au contact de la face de la seconde couche ne comportant pas de rainures, et à relier les deux dites première et seconde couches de façon qu'elles présentent entre elles la possibilité d'au moins un léger glissement l'une sur l'autre.The object of the present invention is therefore to implement a method for producing an anti-vibration mat which overcomes the drawbacks mentioned above, by making it possible to produce large surfaces at a very low cost price. insulation against any type of vibration and also contributing to the protection of the environment. More specifically, the subject of the present invention is a method for producing an anti-vibration mat, characterized in that it consists in producing a first layer of a first visco-elastic material, in producing a first set of grooves on one face of this first layer, to make a second layer of a second viscoelastic material, to make a second set of grooves on one face of this second layer, to superimpose the two said first and second layers one on the other of so that the first set of grooves is in contact with the face of the second layer having no grooves, and to connect the two said first and second layers so that they present the possibility of at least a slight sliding one over the other.

D'autres caractéristiques et avantages de la présente invention apparaîtront au cours de la description suivante, donnée à titre illustratif mais nullement limitatif, d'un mode de mise en œuvre préférentiel du procédé selon l'invention par référence aux dessins annexés à titre illustratif dans lesquels:Other characteristics and advantages of the present invention will appear during the following description, given in By way of illustration but in no way limiting, of a preferential mode of implementation of the method according to the invention by reference to the drawings annexed for illustrative purposes in which:

Les figures 1 et 2 représentent, sous forme schématique, respectivement une vue de dessus et une vue en coupe d'un mode de réalisation d'un tapis antivibratoire obtenu par la mise en œuvre du procédé selon l'invention, la coupe représentée sur la figure 2 étant référencée II-II sur la figure 1.Figures 1 and 2 show, in schematic form, respectively a top view and a sectional view of an embodiment of an anti-vibration mat obtained by the implementation of the method according to the invention, the section shown in the Figure 2 being referenced II-II in Figure 1.

Le procédé selon l'invention pour réaliser un tapis antivibratoire consiste à réaliser une première couche 1 d'un premier matériau visco-élastique, à réaliser un premier ensemble de rainures 2 sur une face 3 de cette première couche 1, à réaliser une seconde couche 4 d'un second matériau visco-élastique, à réaliser un second ensemble de rainures 5 sur une face 6 de cette seconde couche 4, à superposer ces première et seconde couches l'une sur l'autre de façon que le premier ensemble de rainures 2 soit au contact de la face 7 de la seconde couche ne comportant pas de rainures, et à relier les deux couches 1 et 4 superposées, de façon qu'elles présentent entre elles la possibilité d'au moins un léger glissement l'une sur l'autre. De façon avantageuse, au moins l'une des deux première et seconde couches comportant des rainures sur l'une de ses faces est réalisée de la façon suivante au moyen de pneumatiques pour roues de véhicules automobiles: élimination des deux flancs latéraux des pneumatiques pour ne laisser que la bande de roulement, découpe de la bande de roulement suivant au moins un plan axial de cette bande, et aplatissement de la bande de roulement découpée.The method according to the invention for producing an anti-vibration mat consists in producing a first layer 1 of a first visco-elastic material, in producing a first set of grooves 2 on a face 3 of this first layer 1, in producing a second layer 4 of a second visco-elastic material, to produce a second set of grooves 5 on a face 6 of this second layer 4, to superimpose these first and second layers one on the other so that the first set of grooves 2 or in contact with the face 7 of the second layer having no grooves, and connecting the two superposed layers 1 and 4, so that they present the possibility of at least a slight sliding one on the other. Advantageously, at least one of the first and second layers having grooves on one of its faces is produced in the following manner by means of tires for motor vehicle wheels: elimination of the two lateral sides of the tires so as not to leave only the tread, cutting the tread along at least one axial plane of this tread, and flattening the cut tread.

De façon préférentielle, pour obtenir des tapis antivibratoires de grandes dimensions, au moins l'une des deux couches, et avantageusement les deux, est réalisée par la juxtaposition, sensiblement dans un même plan, de plusieurs bandes de roulement découpées et aplaties comme décrit ci-avant.Preferably, to obtain large anti-vibration mats, at least one of the two layers, and advantageously both, is produced by the juxtaposition, substantially in the same plane, of several cut and flattened treads as described below. -before.

Les deux couches avec les rainures, ainsi réalisées, sont superposées comme décrit ci- avant et de façon que les bandes 11, 12, ... constituant l'une 4 des deux couches sont sensiblement perpendiculaires aux bandes 13, 14, ... constituant l'autre couche 1.The two layers with the grooves, thus produced, are superimposed as described above and in such a way that the strips 11, 12, ... constituting one of the two layers are substantially perpendicular to the strips 13, 14, ... constituting the other layer 1.

Dans le but d'obtenir un amortissement important des vibrations et de réduire la transmission de ces vibrations d'une couche à l'autre, les deux couches ne sont reliées l'une à l'autre qu'en des points 15 séparés les uns des autres. Ces points de liaison 15 sont obtenus par au moins l'une des techniques suivantes: agrafage, collage, rivetage, etc. Dans la mise en œuvre du procédé qui a conduit à la réalisation du tapis schématiquement illustré sur les figures 1 et 2, les deux couches 1 et 4 sont reliées point par point au moyen d'agrafes 16.In order to obtain significant damping of vibrations and reduce the transmission of these vibrations by layer to another, the two layers are connected to each other only at points 15 separated from each other. These connection points 15 are obtained by at least one of the following techniques: stapling, gluing, riveting, etc. In the implementation of the process which has led to the production of the carpet schematically illustrated in FIGS. 1 and 2, the two layers 1 and 4 are connected point by point by means of staples 16.

Il est précisé que, bien que le procédé selon l'invention ait été décrit ci-dessus dans le cas de la réalisation d'un tapis antivibratoire comportant deux couches de matériau visco-élastique, il pourra, sans sortir du cadre de l'invention, être utilisé pour la réalisation d'un tapis antivibratoire comportant plus de deux de ces couches. Comme mentionné ci-avant, de tels tapis antivibratoires peuvent être disposés en tous lieux et sont notamment destinés à être enterrés. Pour éviter que des graviers, sables, etc, ne s'introduisent dans les rainures et ne diminuent le pouvoir d'amortissement des tapis antivibratoires obtenus par la mise en œuvre du procédé selon l'invention, il est avantageux d'envelopper dans une toile protectrice 18 l'ensemble des deux couches superposées et reliées entre elles comme décrit ci-dessus. Cette toile protectrice 18 est constituée par exemple d'un tissu géo textile.It is specified that, although the method according to the invention has been described above in the case of the production of an anti-vibration mat comprising two layers of visco-elastic material, it may, without departing from the scope of the invention , be used for the realization of an anti-vibration mat comprising more than two of these layers. As mentioned above, such anti-vibration mats can be placed anywhere and are in particular intended to be buried. To avoid that gravel, sand, etc., get into the grooves and reduce the damping power of the anti-vibration mats obtained by implementing the method according to the invention, it is advantageous to wrap in a canvas protective 18 all of the two superimposed layers and connected together as described above. This protective fabric 18 consists for example of a geo-textile fabric.

Le procédé selon l'invention est particulièrement avantageux car il peut être mis en œuvre en utilisant des pneumatiques usagés.The method according to the invention is particularly advantageous because it can be implemented using used tires.

En conséquence, outre le fait que la structure des tapis ainsi obtenus leur confère une excellente qualité antivibratoire, ce procédé permet d'employer utilement des produits qui deviennent actuellement des déchets dont le stockage pose des problèmes importants.Consequently, in addition to the fact that the structure of the carpets thus obtained gives them an excellent anti-vibration quality, this process makes it possible to use products which are currently becoming waste, the storage of which poses significant problems.

Il est donc évident que, en plus de présenter des avantages fonctionnels, le procédé selon l'invention contribue à la sauvegarde de l'environnement. It is therefore obvious that, in addition to having functional advantages, the method according to the invention contributes to protecting the environment.
