Definitions

  • the present invention relates to improvements made to arrangements for absorbing or reflecting airborne noise from the road or rail traffic.
  • the present invention relates more particularly to walls forming acoustic protection screens and metal posts for the realization of these walls.
  • Acoustic screens are generally made up of panels superimposed fixed on regularly spaced posts.
  • the invention presented aims to modify the posts of these screens to improve their cost, their ease of installation and their aesthetics.
  • this type of post is essentially consisting of a straight section of metal beam (or profile), the cross section profile is H or I shaped; this is the case posts for noise barriers described in patents FR 2 737 514 and EP39984; such posts allow engagement in each of the two vertical grooves which they delimit, from the lateral edge of a re-entrant panel in the constitution of the wall; however the use of fasteners and / or of immobilization of the panels in the grooves of the post, such as the U-shaped connection means described in patent n ° EP39984, has drawbacks: these screw and jumper clamping systems expandable are expensive and time-consuming to install, especially since the wall height is high.
  • the strong projection posts and numerous blocking devices the length of which generally greater than 50 mm and may exceed 200 mm is unsightly on the back side.
  • the difficulties are increased when the panels are heavy, especially when using panels containing sand and / or aggregates - such as concrete-based panels; the mass of such panels can indeed exceed one ton.
  • Document No. FR 2 737 514 describes a screen wall made up of panels with a central concrete layer engaged by its edges lateral in U-shaped housings formed by poles with shaped cross-section of H; the thickness of this layer being greater than the width of the housing, it has recesses resulting in a thickness reduced allowing to embed the branches of H in the central layer; an outer layer fixed on each face of the central layer, covers the post to form a continuous sound barrier.
  • An object of the invention is to remedy, at least in part, the disadvantages of known anti-noise walls and poles entering their constitution.
  • the post further comprises a fourth blade, also called rear sole, which extends longitudinally (along the H-beam), substantially perpendicular to the central core, which is inclined with respect to said first and second blades, preferably at an angle of inclination whose value is in a range from 0.5 to 10 degrees - in particular of the order of 1 to 5 degrees -, which extends from the base of the post up to a height at least equal to the half height of the post;
  • the pole preferably further comprises at least a fifth blade longitudinal extending between the intermediate wing and the rear sole and connecting these; said fourth and fifth blades are preferably planar, and said fifth blade is preferably substantially parallel to the central core (third blade), in particular in the extension of this one.
  • This reduction in the width of the U-shaped groove eliminates (or decreases) in addition the risk of dislocation of the panel out of the groove in the absence of a wedging member, which in particular improves the conditions of safety during the nesting (by sliding) of the panels introduced by the upper end of the grooves; this operation is in very delicate effect: the heavy panel being suspended from a lifting device, its pivoting is free and can cause the fall of the human being - usually raised in a basket to a height often exceeding 4 or 5 meters - which guides the edge of the panel to insert it into the groove.
  • the length of the fourth blade is in the range of 50 to 90% - especially 60 to 80% - of the height of the post; thereby the upper end of the post which is not reinforced lends itself, due to the reduced inertia of the portion to H section (or double U), to a deformation (in bending) of several millimeters, under a modest effort applied manually by the operator guide to facilitate the insertion of the panel into the groove; this is also facilitated by the inclination of the fourth blade: indeed this is close - for example flush - to the U-shaped grooves at its end upper where it adds little inertia and therefore little resistance to bending ; because of this inclination it regularly deviates from the grooves, in direction of the base of the post, which gives the post an inertia - and by therefore resistance to bending - increasing from top to bottom; so the gradual distance of the fourth blade from the first blade as you get closer to the base of the post allows a increase of the inertia of
  • the fourth blade can be curved and can in this case extend for example the ends of said second blade, it is preferably flat.
  • the cross section of the fourth blade is generally at less equal to that of the first blade, in particular of the order of 150% at 500% of it; this increases the resistance of the post; according to a first preferred embodiment, the width of the fourth blade is for this purpose greater than the width of the first blade; according to another mode of realization the thickness of the fourth blade is greater than the thickness of the front sole (first blade), over at least part of its section; in the two embodiments which can be combined, the surface of the cross section of the fourth blade is greater than that of the first blade, on the lower part of the post where the fourth extends blade; to increase this progression in post resistance by lower part, the width of the rear sole (fourth blade) can be increasing from top to bottom; this improves the resistance of the post to spill.
  • the post is produced by welding of an H profile (delimiting the grooves) and of a part with an H profile T constituting said fourth and fifth blades; the "leg" of the T extends in the extension of the central core (the H bar) and is linearly increasing height; the T-shaped part can in particular be obtained by (symmetrical) cutting of an I-profile along an inclined line relative to the longitudinal axis of the profile.
  • the post is produced by welding along an H-profile, of a part with a section profile transverse is U-shaped, the free ends of the wings of the U being welded, over the entire length of the part, onto said second blade (wing intermediate); the assembly then forms a hollow beam whose section has a closed outline; this allows to use for the realization (by folding) of the U-shaped part, a thin sheet (thickness of the order of 4 to 10 mm) while ensuring significant inertia along the two axes transverse.
  • the different metal blades constituting the post are made of steel, the breaking strength of which is at least equal to 235 Mpa.
  • Figures 1 to 3 and 6 illustrate the known construction technique walls with H-posts;
  • Figures 1 and 3 illustrate a view in schematic section through a horizontal transverse plane, a post receiving the side ends of two adjacent panels partially represented;
  • Figure 2 similarly illustrates the lateral end cracked panel;
  • Figure 6 illustrates a perspective view of a post in the grooves of which the ends of two panels are housed adjacent.
  • Figures 4, 5 and 7 to 9 illustrate a first embodiment of the invention in which the post consists of an H profile reinforced by a T-profile over part of its height;
  • Figure 7 illustrates this mode of realization in the same way as Figure 6;
  • Figures 8 and 9 illustrate schematically in perspective, respectively a rear view and a view from the front, a portion of a wall with four posts and six panels stacked two by two;
  • Figure 5 illustrates in cross section the post in its reinforced part;
  • figure 4 illustrates in the same way that in Figures 1 and 3 the post in the grooves of which are engaged two adjacent panels.
  • Figures 10 and 12 illustrate a second embodiment of the invention
  • Figures 11 and 13 illustrate a third embodiment of the invention
  • Figures 10 and 11 are perspective views schematic and Figures 12 and 13 are respectively a sectional view along C-C in Figure 10 and a sectional view along A-A in Figure 11.
  • Figure 14 illustrates in side view a post such as those of the figures 10 and 11;
  • Figure 15 illustrates the cross section of a post entirely made of folded sheet metal and fitted with a curved rear sole;
  • the figure 16 illustrates the cross section of a corner post for the support of two adjacent non-aligned panels.
  • Stacked panels are held in position by bolts 3 screwed into waiting sockets 4 and supported on the rear face of the post or Rear sole 9 ( Figure 1).
  • the post On each side face of the post a groove marked 15 in the figure 5 is provided, allowing the panel to slide without being necessary to place shim bolts; the post has on each side lateral and preferably over its entire height said groove (or groove) extending vertically, of width adapted to the concrete wood panel or similar, preferably larger by 5 mm to 15 mm than the thickness of said panels, so that the vertical lateral edge of a panel can be inserted into said groove, if necessary after countersinking (or notch) along said edge of the panel.
  • Timing bolts are however preferably provided for allow perfect alignment on the front and rear sides, even if narrow gorges; these bolts are shorter and not very visible; when the panels are inserted in the H the bolts are screwed to the maximum, only their heads sticking out so that they cannot twist.
  • the invention offers advantages: the notches with realize in the panel to conceal the front sole are less deep, the panel ends are less fragile, which reduces the risk of crack identified 6 in Figure 2; we can avoid the installation of said cover, which is long to realize and requires the use of nacelles for the working at height, hence a significant saving.
  • Buttresses marked 16 in FIG. 7 placed in a plane perpendicular to the post axis increase resistance to spill; reducing the weight of the posts results in savings sensitive.
  • the metal pole specially designed to serve as a support for 2 panels entering the construction of an acoustically insulating wall is provided, in the lower part less, an increasing inertia (and / or cross section and / or width) of front to back, which gives it an improved aesthetic form, a mechanical resistance adapted to the load to be supported, mass and cost diminished.
  • the core comprises a front part 13a, forming said third blade, which delimits the two grooves 15 with the blades 11, 12, the assembly forming an H; the part 13b forming the fifth blade, extends in the extension of the part 13a, and forms with the rear sole 14 a T; the "foot" 13b 1 of the "leg” 13b of the T is welded, over the entire length of the T-reinforcement, on the median line of the external face of the blade 12; the T-profile whose leg 13b is of variable (linearly) length is obtained by cutting a standard I-profile.
  • the structure of reinforcement of the H-profile receiving the panels forms with it a hollow beam with closed profile; according to Figures 10 to 14, this structure - which extends about two-thirds of the height of the H profile - has a profile transverse in the shape of a flared U (figure 13) or on the contrary "pinched" (figure 12): this structure comprises the rear sole 14 (fourth blade) and two fifth blades 30 and 31 which each connect one end of the blade 14 to one end of the blade 12; the blade 14 is reinforced by a bar 32 extending along it, inside (figure 13) or outside (figure 12) of this reinforcing structure.
  • This U-shaped structure can be obtained by folded and welded on a standard H profile (figure 12) or reconstituted (Figure 13 where the blade 12 is wider than the blade 11).
  • the blades 11 to 14 are obtained by folding and the blade 14 is domed; in FIG. 16, the structure for holding the panels in the grooves 15 is made up of two U-shaped section profiles comprising each said blades 11, 12 and 13a; these profiles are joined by a blade additional 13c, and are in contact along a generator along which they are connected to the T profile 13b, 14.
  • the invention also provides a wall bordering a road or a railway track for the acoustic protection of the neighborhood, which comprises ( Figures 8, 9) a plurality of vertical panels 2 stacked, which are held by a plurality of posts 1 according to the invention, extending vertically and between two adjacent stacks of panels; each post has a groove on each side face in which is engaged the edge 21 (and / or edge) lateral and vertical of the panels.
  • Said panels are preferably made of concrete 2a (figure 2), and / or terracotta, and / or metal, and / or aluminum, and / or plastic and / or recycled rubber, and / or tires and / or topsoil comprising at least on a face 2b an acoustic absorbent material 2c in masonry and / or rock wool, and / or wood, and / or wood chips amalgamated with concrete (concrete-wood type or similar), and / or lava concrete, and / or glass, and / or polycarbonate, and / or shavings of recovered electrical wires.
  • Said panels are preferably of the following dimensions: Length 3 m to 6 m Height 1 m to 2 m Weight 100 to 800 kg / m 2 in particular 400 kg / m 2 .
  • the process makes it possible to avoid making men work at height, avoid the use of carrycots and thus contribute to savings substantial equipment and manpower.
