Definitions
- the present invention relates to a noise barrier intended to attenuate the perception of a noise source in a protected area, for example a residential area.
- the sheet piles of the finished work can be painted or decorated in such a way that the wall harmonizes with the environment or there confuses.
- the sound propagation wave is for the essentials reflected on the noise barrier built in concrete or by assembling metal sheet piles and it is returned in the direction of the source which is at its origin, up to sometimes a kilometer beyond this source.
- the structure bearing of such a wall is then ensured either by precast concrete profiles, either by fire-galvanized steel pillars or by hollow posts of which the part planted in the ground is provided with orifices through which flows concrete injected into the ground, throughout the area surrounding the post, from the inside of the post, the concrete having been poured into the post under pressure a nozzle placed at the top of it.
- DE-A-42 12 172 describes this latest technique.
- the present invention proposes to remedy all of the aforementioned drawbacks. It aims to optimize the establishment of a noise barrier designed to reduce the perception of a noise source in a area to be protected, regardless of the location and the type of soil of implantation.
- the invention recommends the use of absorbent panels, of wood or of BBS type, therefore not self-supporting, the structure bearing such panels being obtained by the provision of thin metal posts, therefore robust but at the same time light, which can be installed in the ground anywhere, without the need for equipment heavy and bulky, therefore posts for quick installation - which can meet urgent work - and moreover reliable, robust and inexpensive.
- the present invention first relates to a wall anti-noise composed of sound absorption elements, constituted by panels in an absorbent material, for example wood or BBS type, each of said absorbent panels being associated with a rigid support, and of a supporting structure supporting said elements and consisting of a plurality of posts arranged at substantially regular intervals along a line substantially parallel to the track, rail or road, to be isolated, each of said posts being provided staples which support said absorbent panels and whose position height on the post is adjustable, said wall rising at the edge of the track over a height greater than the distance separating the noise source from the ground in which it is installed, and being characterized in that the associated rigid support each panel is formed by a profile, preferably metallic, comprising a flat core with a loop along each of its two longitudinal edges horizontal, the upper loop of the support of each panel being able to cooperate by engagement, by horizontal longitudinal displacement, with the lower loop of the support of the upper level panel (s).
- an absorbent material for example wood or BBS type
- the supporting structure consists of posts guarantees the speed, simplicity and low cost of implementing a such structure as well as the adaptability of said structure to all types of terrain, consecutive to its lightness, on the one hand, and to its mode of implantation which does no need for special equipment, on the other hand.
- the width of the rigid support associated with each absorbent panel is at least equal to the height said panel.
- the rigid support associated with each absorbent panel is arranged on that of the two large faces of the panel intended to be placed opposite the plane formed by the line of posts.
- the absorbent panels are rectangular and longitudinally assembled to others by interlocking.
- the absorbent panels are placed horizontally lengthwise and they are staggered.
- This horizontal arrangement of rectangular panels helps to eliminate any differences in slope of the terrain on which the noise barrier is built.
- the panels of the same horizontal line are simply abutted, i.e. there is no imperative as to the fixing between them such absorbent panels located on the same level. Because of this last freedom, it is easy to understand that we can ensure continuity the noise barrier according to the invention exactly in parallel with the track to be insulated, both in its strictly rectilinear parts and in the curvilinear parts, namely in the wide bends made by road or rail. Indeed, two adjacent panels of the same horizontal line can be located in vertical planes which, between them, make an angle of a few degrees.
- the arrangement of the staggered panels makes it possible to avoid the defect "of effect hinge "frequently encountered on all wall constructions in which, by construction obligation, all the panels are aligned in columns from the concrete or steel pillars.
- each of said posts consists of an open quadrangular tube longitudinally on that of its faces which faces the noise source, and clips to fix the sound absorption elements on the post are arranged in line with the opening of said post, so that said elements sound absorption are between the noise source and the pole line.
- each of said posts consists of a quadrangular tube open longitudinally on the side which is furthest from the noise source, and the staples allowing the sound absorption elements to be fixed on the post at the opening of said post, so that the line of posts is between the noise source and said sound absorption elements.
- each post is made in two parts, a hollow tubular base, stuck in the ground, and the post proper, including the lower part, intended to be forcibly engaged in the base, is straight and of a congruent and slightly outer section less than the internal section of said base.
- the upper part the post which emerges from the base is advantageously of square or rectangular section, C-shaped, the opening of this C being framed longitudinally by two returns, substantially the same width, themselves formed of two wings, the first wings of these returns defining with the opening one of the four faces of the post and the second wings of said returns, which border the opening, being turned towards the inside of the post.
- the supporting structure of the noise barrier to the aforementioned particularities is for all or part consisting either of posts essentially vertical, or vertical posts with a hanger at their top, either of vertical posts of which all the part which emerges from the base is curved, either of posts inclined for all or part on the vertical.
- each clip is shaped like an S, the free part of this S extending upwards and being at its end folded back on itself, towards the opening of the post to which the clip is subject, to form a pin, said free part of the S fixing by the inside of its pin the end of the loop of the upper support which is attached to it associated and guiding and supporting from the outside of said pin the loop of the support which is also associated with it.
- the wall according to the invention has staples which are inserted in the interlocked loops of the supports of two panels.
- the noise barrier 5 must therefore absorb as much as possible of the transmitted energy.
- index R its transmission weakening index
- I 2 the intensity transmitted by the wall.
- TGV rail lines cause nuisance to local residents over distances of up to one kilometer from tracks 12.
- the noisy part of any TGV train 11 is at the level of all the rolling parts of the cars power cars and wagons, that is to say up to a height 13 of about one meter soil 2.
- Each of the anti-noise walls comprises a supporting structure supporting acoustic absorption elements, said supporting structure consisting of a plurality of posts 16 arranged at substantially regular intervals along a line substantially parallel to the tracks 12.
- the vertices of the two lines of posts 16 define the vertices of the two walls 15.
- Each post 16 therefore rises above the ground 2 over a height H clearly greater than the distance h separating the noise sources 13 from the level of the tracks 12, c ' is to say clearly greater than one meter.
- the top 17 of the latter is located at the bottom of the windows of the cars in the oar 11 so that the passengers 18 of this train looking horizontally along the arrow marked by 19 have not a vision obstructed by the walls 15.
- each post 116, 216, 316, 416, 516 of such a supporting structure belongs to a vertical plane which extends substantially perpendicular to the direction D of the wall, therefore to the direction of the tracks 12.
- said post taken up then under its overall reference 16 is advantageously constructed from two elements: a straight tubular base 20, plugged into the ground 2, and the post 16 proper, of which the lower part 21 cooperates by an adjustment without play with the base 20, and to this end is therefore also straight.
- Each base 20 is for example formed by a tube of square section, tube whose internal dimension on each side is 102 millimeters.
- the lower part 21 of the post 16 is congruent with the base 20, that is to say the same square shape as said base; each side of this part 21 of the post 16 then has an overall dimension of 100 millimeters, so that this part 21 can be forced into base 20.
- the base 20 is bevelled according to 22 at its lower end, so that it can be more easily inserted into the ground 2.
- Said base is preferably also provided, on its parallel face at tracks 12 and the closest to said tracks, a trapezoid-shaped plate 23 isosceles whose large base is flush with the ground 2, the function of such a plate called " retained "being to improve the resistance of the bearing structure to the forces, so much in the wind.
- a second plate 24, likewise isosceles trapezoidal shape, whose short sides converge downwards, is associated at each base 20, near its end bevel 22, on the face opposite to that which is provided with the first retaining plate 23, in order to further improve the stress resistance characteristics of the bearing structure of the wall according to the invention.
- Such bases are in themselves known and they are marketed under the brand "PROPICLO" .
- the post proper both in its part 16 which emerges from the base 20 only in its part 21 which is forcibly engaged in said base, is open longitudinally, for example on that of its faces 25 which is facing the tracks 12.
- the post thus has a section in C, the opening 26 of this C being framed longitudinally by two returns, substantially the same width, themselves formed of two wings, the first wings 27 of these returns defining with the opening 26 said face 25 facing the source 13 and the seconds wings 28 of said returns, which border the opening 26, being turned inwards of the post ( Figure 6).
- the load-bearing structure defined above supports panels in an absorbent material, based in particular on wood, either pure wood, or and preferably of the BBS type.
- Each absorbent panel 29 is preferably of rectangular shape, and very elongated. Each of said panels is associated with a rigid support 30 disposed on that of its two large faces 31 intended to be placed opposite the plane formed by the line of posts 16 (116, 216, 316, 416, 516).
- the assembly consisting of such a panel 29 and such rigid support 30 which is associated with it is identified by 33 on the wall 15.
- the rigid support 30 is constituted by a profile, preferably metallic, whose length is equal to that of the panel 29 and whose width is at least equal to the height L of said panel.
- the section in question comprises a flat core 34 provided with a loop along each of its two horizontal longitudinal edges, the upper loop 35 being able to cooperate by engagement, by horizontal longitudinal displacement, with the lower loop 36 of the support 30 of the or sets 33 of the upper level.
- the upper loop 35 will also be called the “female” loop and the loop lower 36 will also be referred to as a "male” loop.
- each post 16 from the wall 15, in its part which emerges from the ground 2, is provided with staples 37 whose position height on the post is adjustable. These staples are shaped like S and they are arranged in line with the opening 26 of the post 16.
- Each clip 37 shaped as S extends to the essential upwards, freeing itself from the post to which it is subject and, at its free part said clip is folded back on itself, at its end, towards of the opening 26 of the post, to form a pin 38.
- Each clip 37 is fixed to the post 16 by the forecast a screw 39 with a particular head, whose dimensions and cut allow its engagement in the opening 26 of the post at C, then its blocking in rotation inside such a pole.
- the head of such a device 39 is formed of a base whose width is slightly less than the width of the opening 26 and whose length is substantially less than the dimension inside the side of the C-profile. The height of this base is less than the dimension interior of such a side reduced by the width of the second wings 28.
- one of the two large faces of such a base is provided with two rectilinear grooves 40, able to cooperate with the free edges 28 ′ of the second wings 28, and of a threaded rod 41 which extends orthogonally, substantially from the center of said face of the base.
- the base can advantageously be slightly lower than in its two 40 'parts which border on the outside said grooves.
- Each clip 37 is pierced with an orifice allowing the passage of this threaded rod 41, and the assembly consisting of a clip and a screw special 39 is supplemented by a washer 42 and a nut 43 whose thread is complementary to that of the rod 41.
- the fastening of the clip 37 on the post is obtained first by the introduction of the head of the screw 39 into the opening 26, by its dimension (width) narrowest, less than the width of said opening, then by the rotation (shown diagrammatically by the arrows 47) at 90 ° of this head so that it occupies its normal operating position shown in Figure 6.
- the base of the clip 37 substantially the same width as that of the side of the C profile, is then applied against the front face 25 of this profile 16, by progressive tightening of the nut 43 on the threaded rod 41.
- the head of the screw 39 advances itself in the direction of this face 25 and the second wings 28 of the profile 16 penetrate the grooves 40, so that the head of the screw is this time locked in rotation.
- the clip 37 is easily adjustable in height position.
- the nut 43 is definitively tightened until the edges 40 'of the front face of the head of the screw 39 come to bear against the first wings 27 of the face before 25 of the C profile. Tightening is then effective.
- each post 16 on the front face 25 thereof, a hook 44 ( Figure 9) whose top comprises two tabs 45 which penetrate the C-shaped profile, behind the face 25, of on either side of the second wings 28, and the base of which forms a return 46 towards the front and upwards, capable of receiving the female loop 35 from a first assembly 33.
- the assembly thus supported is supported by its lower part, say by its male loop 36, against the face 25 of the post 16.
- the internal width of the pin 38 is barely greater than the thickness of the sheet from which said support 30 is profiled.
- loops respectively lower and of any support are complementary in shape, and that two supports can thus snap into each other, by longitudinal displacement horizontal.
- assemblies 33 are integral from each other in the height direction, with however a degree of freedom around a horizontal axis 35-36, but that on the other hand such sets are independent of each other in the longitudinal direction, and that the panels 29 simply come to lean one behind the other by their vertical edges 48.
- hooks 44 constituting the attachment member of the upper assemblies 33 of the noise barrier according to the invention can be of any other nature and they can, for simplification, be replaced by staples 37.
- the hooks can also be the first type mentioned above, and be two in number per post 16, the width of each hook 144 then being slightly less than the width of the wing 27 and the two legs 45 becoming one ( Figure 9).
- the assemblies 33 are either mounted in factory, or installed on site.
- each panel 29 is offset by a third of its length by relative to the panel immediately above it and relative to the panel which is immediately lower.
- Such an arrangement has a pitch P which is equal to the length of a panel 29. Provision is therefore made for burying posts while respecting the same pitch P , it being specified here that in the event that the pitch of the posts is not respected exactly, the offset is easily caught up in that, in their longitudinal position, the panels can be more or less moved relative to the clips 37 which support them.
- the invention is not limited to the mode of application no more than to the embodiments which have been mentioned and can design various variants without departing from its framework. So, the example of application was given along a railway track, but it is obvious that a noise barrier of the same kind can be placed at the edge of a road or motorway. It is also conceivable that, to alleviate the sound absorption structure 29-30, the rigid supports 30 are perforated with level of their souls 34. Such perforations, illustrated in FIG. 10 by the marks 50, reduce the weight of the assemblies 33, without affecting their acoustic quality since the supports 30 do not participate in the absorption of sound. Finally, in substitution of the construction variant illustrated in FIGS.
