  • DETAILED DESCRIPTION
  • FIG. 1 depicts an exemplary sound barrier 10 according to the present invention and utilized along a roadway 12 to eliminate or reduce noise transmitted from the roadway 12 to the adjacent area on the opposite side of the sound barrier 10. The sound barrier 10 comprises a series of elongate wall sections 14 disposed between generally vertically extending posts 16. In this embodiment, the wall sections 14 comprise a plurality of sound arresting members 18 arranged end-to-end and stacked in a vertical direction, one atop another, to create a wall or partition between the noise generating area and the area to be protected. The sound arresting members 18 are supported at their respective ends by the spaced apart posts 16, which have been arranged along the boundary between the noise source and the protected area. In FIG. 1, the sound barrier 10 is constructed along the side of the roadway 12 and is positioned atop a parapet or retaining wall 20. It will be recognized however that the sound barrier 10 may alternatively be erected directly upon the ground surface, or in various other configurations, as may be desired.
  • A sound barrier 10 in accordance with the principles of the present invention is suitable not only for new installations, but may also be used to retrofit existing sound walls, for example, when it is desired to repair or replace portions of an existing sound wall or an entire sound wall all together. In the exemplary embodiments shown in FIGS. 4-6, the sound barrier 10 comprises at least one generally vertically extending post 16 spaced apart along the boundary of an area where it is desired to locate the sound barrier 10. Each post 16 has a generally I-shaped cross-section defined by a central structural web 30 and having spaced apart pairs of flanges 32 a, 32 b, 32 c, 32 d extending generally perpendicular to the central web 30 to define first and second oppositely disposed channels 34 a, 34 b along the vertical length of the post 16.
  • A sound barrier 10 may also include a post cap 17 and/or a post cover 19, as described in U.S. Pat. No. 8,561,360, the disclosure of which is incorporated by reference in its entirety.
  • Referring now to FIGS. 2 and 3, and with continued reference to FIG. 1, a spacer bracket 22 for use in sound barrier 10 may include a base portion 24, a first arm 26, and a second arm 28. The first and second arms 26, 28 may be substantially perpendicular to the base portion 24 such that the spacer bracket 22 may have a generally U-shaped cross section. Moreover, the first arm 26 may comprise a length that is substantially greater than the length of the second arm 28 to provide clearance for attaching mounting hardware, such as a rivet 29, through the first arm 26 into a wall section 14, as depicted in FIG. 4. In one embodiment, the longitudinal length L of the bracket 22 may be substantially equal to the height H of a corresponding wall section 14. In one embodiment, the U-shaped bracket 22 may comprise a glass-reinforced polymeric material, such as fiberglass reinforced plastic (FRP). It will be appreciated, however, that spacer bracket 22 may alternatively be made from various other materials suitable for supporting a wall section 14 as described below.
  • Referring now to FIG. 4, a sound barrier 10 may comprise wall sections 14 a, 14 b received in channels 34 a, 34 b along post 16. The sound barrier 10 may further include brackets 42 disposed within the channels 34 a, 34 b. In the embodiment shown, the brackets 42 have generally L-shaped cross-sections. First legs 44 of the L-shaped brackets 42 may be secured to the posts 16 along the central web 30, while second legs 46 of the L-shaped brackets 42 may extend perpendicular to the central web 30. The brackets 42 may cooperate with flanges 32 c, 32 d to define spaces within channels 34 b, 34 a sized to receive wall sections therebetween. For example, the right side of FIG. 4 depicts a wall section 14 b having a thickness T that is substantially equal to the distance between a bracket 42 and a flange 32 d and that is received in channel 34 b in the space between the bracket 42 and flange 32 d. In one embodiment, the wall section 14 b may comprise concrete. The left side of FIG. 4 depicts a wall section 14 a having a thickness t that is substantially less than the distance between a bracket 42 and a flange 32 c and that has been installed in channel 34 a in the space between the bracket 42 and the flange 32 c to replace a thicker wall section that was originally disposed in channel 34 a. The wall section 14 a may be thinner and lighter than the wall section 14 b. In one embodiment, the wall section 14 a may comprise a glass-reinforced polymeric material (e.g. fiberglass). Sound barrier 10 may further include a U-shaped spacer bracket 22 positioned within the channel 34 a between the wall section 14 a and the L-shaped bracket 42. In this manner, the L-shaped bracket 42 may provide a stop surface to the second arm 28 of the U-shaped bracket 22 such that the wall section 14 a may engage a flange 32 c of the post. The first arm 26 of the U-shaped bracket 22 may be coupled with the wall section 14 a for support, such as by rivets 29 or other fasteners. Alternatively, it will be appreciated that the first arm 26 may be coupled with the wall section 14 a by any other suitable method of attachment, such as by adhesion or welding. In addition, one or more shims 47 may be positioned between the second arm 28 of the U-shaped bracket 22 and the second leg 46 of the L-shaped bracket 42 to provide a tight fit.
  • In many instances, it may be desirable to replace a thick wall section 14 b with a thinner wall section 14 a. For example, a thick wall section 14 b made of concrete may be heavy and difficult to maintain, repair, or replace after being exposed to damage or weathering. Conversely, a thinner wall section 14 a made of fiberglass may be lightweight and easily replaceable. Referring now to FIG. 5, and with continued reference to FIG. 4, the wall section 14 b may be replaced with a second wall section 14 a having a thickness t that is substantially less than the distance between a bracket 42 and flange 32 d. Sound barrier 10 may further include U-shaped brackets 22 positioned within the channels 34 a, 34 b between the wall sections 14 a and the L-shaped brackets 42. In this manner, the L-shaped brackets 42 may provide stop surfaces to the second arms 28 of the U-shaped brackets 22 such that the wall sections 14 a may engage the flanges 32 c, 32 d of the post 16.
  • Referring now to FIG. 6, wherein similar features are similarly numbered, sound barrier 110 may comprise at least one generally vertically extending post 116 spaced apart along the boundary of an area where it is desired to locate the sound barrier 110. Each post has a generally I-shaped cross-section defined by a central structural web 130 and having spaced apart pairs of flanges 132 a, 132 b, 132 c, 132 d extending generally perpendicular to the central web 130 to define first and second oppositely disposed channels 134 a, 134 b along the vertical length of the post 116. Sound barrier 110 may further comprise wall sections 14 a received in channels 134 a, 134 b along post 116. The wall sections 14 a may have thicknesses t substantially less than the widths of channels 134 a, 134 b. Sound barrier 110 may further include U-shaped brackets 22 positioned within the channels 134 a, 134 b between the wall sections 14 a and the flanges 132 b, 132 a. In this manner, the flanges 132 b, 132 a may provide stop surfaces to the second arms 28 of the U-shaped brackets 22 such that the wall sections 14 a may engage the flanges 132 c, 132 d of the post 116. The first arms 26 of the U-shaped brackets 22 may be coupled with the wall sections 14 b for support, as previously described. In addition, one or more shims 47 may be positioned between the second arms 28 of the U-shaped brackets 22 and the flanges 132 a, 132 b to provide a tight fit. In one embodiment, the wall sections 14 a may comprise a glass-reinforced polymeric material (e.g. fiberglass).
  • While the present invention has been illustrated by the description of one or more exemplary embodiments, and while the embodiments have been described in considerable detail, they are not intended to restrict or in any way limit the scope of the appended claims to such detail. The various features discussed herein may be used alone or in any combination. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and method and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the scope or spirit of the general inventive concept.
