Description
DESCRIPTIONDESCRIPTION
Ecran antîbruit pour voies de circulationNoise barrier for traffic lanes
La présente invention se rapporte aux écrans antibruit et, plus particulièrement, aux écrans en béton préfabriqués, utilisés pour atténuer les bruits nuisants provenant des voies de circulation. Les écrans antibruit en béton existants sont généralement constitués de dalles horizontales que l’on glisse dans des poteaux préalablement scellés dans le sol.The present invention relates to noise barriers and, more particularly, precast concrete screens, used to attenuate harmful noise coming from traffic lanes. Existing concrete noise barriers generally consist of horizontal slabs that are slid into posts previously sealed in the ground.
L’amortissement des bruits provenant des voies de circulation est souvent très insuffisant.The absorption of noise from traffic lanes is often very insufficient.
Le but de la présente invention est d'améliorer les performances de l'amortissement acoustique des écrans antibruit, ainsi que d'augmenter leur stabilité et de faciliter leur mise en place.The aim of the present invention is to improve the performance of the acoustic damping of noise barriers, as well as to increase their stability and to facilitate their installation.
A cet effet, l'écran antibruit, objet de l'invention, est constitué d'une paroi inclinée, munie d'une coiffe, le côté de la paroi soumis à la source de bruit étant au moins partiellement recouvert par un élément amortisseur acoustique.To this end, the noise barrier, object of the invention, consists of an inclined wall, provided with a cap, the side of the wall subject to the noise source being at least partially covered by an acoustic damping element. .
Un autre objet de l'invention est de réaliser un écran antibruit qui soit totalement autoportant.Another object of the invention is to provide a noise barrier which is completely self-supporting.
Afin de mieux comprendre l'invention, on en décrira ci-après un exemple de réalisation pratique à l’aide des dessins annexés, dans lesquels: • la figure 1 est une coupe verticale d'un écran antibruit selon l'invention; • la figure 2 est une coupe longitudinale partielle selon la ligne A-A de la figure 1; • la figure 3 est une coupe verticale d'un écran antibruit selon une variante d’exécution de l'invention.In order to better understand the invention, a practical embodiment example will be described below with the aid of the appended drawings, in which: • Figure 1 is a vertical section of a noise barrier according to the invention; • Figure 2 is a partial longitudinal section along the line A-A of Figure 1; • Figure 3 is a vertical section of a noise barrier according to an alternative embodiment of the invention.
Suivant la figure 1, l'écran antibruit est constitué d'une paroi 10 destinée à être disposée de façon inclinée par rapport au sol 20. En effet, la paroi 10 est inclinée vers la source de bruit pour rabattre celui-ci vers le sol et pour ne pas le réverbérer au-dessus de la paroi antibruit d’en face, évitant ainsi de gêner les autres riverains.According to FIG. 1, the noise barrier consists of a wall 10 intended to be disposed in an inclined manner with respect to the ground 20. In fact, the wall 10 is inclined towards the noise source in order to fold it down towards the ground and not to reverberate it above the noise barrier opposite, thus avoiding disturbing other residents.
A distance appropriée et du côté formant un angle obtus avec le niveau du sol, la paroi 10 est munie de raidisseurs 12 disposés verticalement, faisant corps avec la paroi 10 et pouvant dépasser vers le bas afin de créer des poteaux d ' encastrement 14.At an appropriate distance and from the side forming an obtuse angle with the level of the ground, the wall 10 is provided with stiffeners 12 arranged vertically, integral with the wall 10 and capable of projecting downward in order to create embedding posts 14.
Du côté opposé, la paroi 10 est munie d'un support 16 et, à son extrémité supérieure, la paroi est munie d'une coiffe 18 dépassant de part et d'autre la paroi 10. La coiffe 18 dépasse davantage du côté de la source du bruit dans le but de rabattre au maximum la réverbération des bruits tangents.On the opposite side, the wall 10 is provided with a support 16 and, at its upper end, the wall is provided with a cap 18 projecting on either side of the wall 10. The cap 18 projects more on the side of the source of noise in order to minimize the reverberation of tangent noise.
Conformément à l'invention, on dispose entre le support 16 et la coiffe 18 un ou plusieurs éléments 30 capables d'amortir et d'absorber le bruit.According to the invention, there is between the support 16 and the cap 18 one or more elements 30 capable of damping and absorbing noise.
Ainsi que cela ressort de la figure 2, les éléments 30 sont avantageusement structurés par des rainures 32, afin de créer une surface d'amortissement amélioré contre les bruits.As can be seen in FIG. 2, the elements 30 are advantageously structured by grooves 32, in order to create an improved damping surface against noise.
Les raidisseurs 12 peuvent être de forme et dimensions variables selon les nécessités de rigidité ou d'esthétique.The stiffeners 12 can be of variable shape and dimensions according to the requirements of rigidity or aesthetics.
Un grand avantage de l'écran antibruit selon l'invention consiste dans le fait qu'il est tout à fait autoportant.A great advantage of the noise barrier according to the invention consists in the fact that it is completely self-supporting.
La paroi 10 peut éventuellement être munie d'une semelle 46 en béton qui la rend stable sans autre fondation, ainsi que montré à la figure 3.The wall 10 can optionally be provided with a concrete sole 46 which makes it stable without any other foundation, as shown in FIG. 3.
Cette figure 3 montre une variante de réalisation d'un écran antibruit selon l'invention. En effet, la paroi 40, ainsi que les raidisseurs 42, sont réalisés sous forme courbée vers la source de bruit, également pour rabattre les bruits vers le sol.This Figure 3 shows an alternative embodiment of a noise barrier according to the invention. Indeed, the wall 40, as well as the stiffeners 42, are produced in a curved form towards the noise source, also for reducing the noises towards the ground.
De préférence, la courbure est elliptique et est étudiée en fonction de deux sources de bruits provenant des deux sens de circulation.Preferably, the curvature is elliptical and is studied as a function of two sources of noise originating from the two directions of circulation.
Le support 16 est légèrement plus développé de façon à créer un vide ou espace creux 44 derrière les éléments amortisseurs acoustiques 30 pour en augmenter davantage les performances. Comme déjà mentionné, la paroi 40 est pourvue vers le bas d'une semelle 46.The support 16 is slightly more developed so as to create a void or hollow space 44 behind the acoustic damping elements 30 to further increase its performance. As already mentioned, the wall 40 is provided downwards with a sole 46.
Les éléments amortisseurs acoustiques 30 peuvent être réalisés en tous matériaux appropriés pour absorber les bruits tels que du béton-bois (mélange ciment et granulés de bois), de l'argex, de la laine de verre, etc... La forme et la composition de ces éléments sont adaptées au spectre des fréquences spécifiques de la voie de circulation.The acoustic damping elements 30 can be made of any suitable material to absorb noise such as concrete-wood (mixture of cement and wood pellets), argex, glass wool, etc. The shape and composition of these elements are adapted to the spectrum of specific frequencies of the traffic lane.
La paroi porteuse peut être réalisée en béton armé ou en béton précontraint pour présenter une meilleure résistance au déplacement d’air brusque provoqué, par exemple, par des gros camions ou par des trains à grande vitesse.The load-bearing wall can be made of reinforced concrete or prestressed concrete to have better resistance to sudden air movement caused, for example, by large trucks or by high-speed trains.
Les dimensions et formes de la paroi peuvent être étudiées en fonction des réalisations des architectes-urbanistes, puisque le béton est un matériau pouvant être coulé selon toute forme voulue pour ainsi l'adapter au cas étudié.The dimensions and shapes of the wall can be studied according to the achievements of architect-urban planners, since concrete is a material that can be poured in any desired shape so as to adapt it to the case studied.
