Abstract

The system for absorbing the noise generated by vehicles on rail and motorways consists of applying onto a rigid support cover (4) a cushion of noise absorbent material (3) such as glass wool or rock wool. Spaced inclined strips (1) are placed horizontally to guide the noise towards the absorbent material. The strips also prevent the penetration of rainwater. The noise absorbent material is protected against animal intrusion by a fine non-corroding grill (2) behind the horizontal strips. The removable cover is fixed to the frame (5) by fitting in its upper part (6) and by nuts in its lower part (7). The monobloc element is fixed to the ground by screwing nuts onto threaded rods (8) sealed in a concrete (9).

Description

La presente invention concerne un dis wsitif absorbant les bruits élis par les vehicules en mouvement sur les voies routières et térroviaires
Traditionnellenent la réalisation des murs anti bruit fait appel à des matériaux dont la surface dure et lisse ne fait que refléchir les bruits
Le dispositif selon l'invention permet de remédier à cet inconvénient Il comporte un matériau mou conme la laine de verre ou la laine de roche oui absorbe le bruit .A cause de sa putréscibilité le materiau est protégé des conditions atmosphériques par des lanes disposées horizontalenent espacées et inclinées de tel sorte que les eaux de pluie ne puissent l'atteindre . Pour lutter contre les désordres provoqués par l'intrusion d'animaux .comme les oiseaux .les rongeurs les insectes .un grillage fin inaltérable est posé à l'arrière des lanes horizontales
Le dispositif selon la présente invention est appliqué ici sur un alésent monobloc réalisé en matériau léger conne la matière plastique .l'aluninium .etc
L'element monobloc est rempli du matériau flou absorbant sa forte est galbée sa partie supérieure est légerenent inclinée
Sa hauteur non limitative est en rapport avec la distance le séparant de la source du bruit
La surface concave de l'élément monobloc selon la présente invention reste perméable au bruit .et est exposée vers l'énission du bruit
a surface concave de i'eléient monobloc est ici .selon la presente invention eouipee des lames horizontales dont l'écartement et l'inclinaison guident le bruit vers le matériau absorbant et de protéger celui ci contre les intemperies
lmnediatement à l'arrière des laies horizontales le grillage en metal inaltérable à mailles fines est placé pour lutter contre l'intrusion des animaux rongeurs.oiseaux.insectes.etc ...The present invention relates to a device ws absorbing the noise elected by the moving vehicles on the road and railways.
Traditionnellenent the realization of noise barriers uses materials whose hard and smooth surface does nothing but reflect noise
The device according to the invention overcomes this drawback It comprises a soft material like glass wool or rock wool yes absorbs noise. Because of its putrescibility the material is protected from atmospheric conditions by lanes arranged horizontally spaced and tilted so that rainwater cannot reach it. To fight against disorders caused by the intrusion of animals. Like birds. Rodents insects. A fine, unalterable screen is placed behind the horizontal lanes.
The device according to the present invention is applied here to a monobloc alente made of light material conne plastic .l'aluninium .etc
The monobloc element is filled with fuzzy material absorbing its strong is curved its upper part is slightly inclined
Its non-limiting height is related to the distance separating it from the noise source
The concave surface of the one-piece element according to the present invention remains permeable to noise. And is exposed towards the emission of noise.
a concave surface of the monobloc element is here. according to the present invention fitted with horizontal blades whose spacing and inclination guide the noise towards the absorbent material and protect it against the weather
lmnediately behind the horizontal lanes the unalterable metal mesh with fine mesh is placed to fight against the intrusion of rodent animals.birds.insects.etc ...

La surface convexe de l'élément monobloc ici employé représente le capot .Celui ci amovible permet l'entretien inopiné. The convex surface of the monobloc element used here represents the cover. This removable one allows unannounced maintenance.

La figure 3 représente ici selon l'invention le dispositif applique sur un autre mode de support
En référence a ces dessins le dispositif comporte
-Les laines horizontales inclines et espaces guidant le bruit vers le materiau absorbant et interdissant la pénétration des eaux de pluie et de prolection . (1)
-Le grillage en métal inalterable à mailles fines enpéchant l'intrusion des animaux rongeurs oiseaux ,insectes ,etc... (2)
-Le materiau mou absorbant < 3) laine de verre laine de roche rexpllssant ici la totalité de l'élément monobloc et appliqué d'autre part sur d'autre mode de support. (10)
-Le capot amovible (4) solidarisé a l'ossature (5) par un emmanchement à sa partie supérieure (6) et par des écrous à sa partie inférieure (7) facilitant la manoeuvre pour un entretien inopiné facile .easy of the constituent elements the anti noise device
The noise absorbing device of the present invention has no restrictive application and can be used on other support nodes
The accompanying drawings illustrate the invention
Figure 1 shows a perspective view of the element

anti noise by absorption
Figure 2 shows the section of the one-piece element
demonstrating the arrangement of the components of the anti-noise device
Figure 3 shows here according to the invention the device applied to another mode of support
With reference to these drawings, the device comprises
-The inclined horizontal wools and spaces guiding the noise towards the absorbent material and preventing the penetration of rainwater and prolection. (1)
-The unalterable metal mesh with fine mesh by fishing the intrusion of rodent animals birds, insects, etc ... (2)
-The absorbent soft material <3) glass wool rock wool rexpllssant here the whole of the monobloc element and applied on the other hand on other support mode. (10)
-The removable cover (4) secured to the frame (5) by a fitting at its upper part (6) and by nuts at its lower part (7) facilitating the operation for easy unannounced maintenance.

-La fixation au sol de l'élément monobloc est réalisé avec des écrous vissés sur des tiges filetées (8) scéllées dans une longrine en beton . (9)  -The single piece unit is fixed to the ground with nuts screwed onto threaded rods (8) sealed in a concrete sill. (9)
