Sound wall barrier system and method of constructing same

Abstract

A sound wall barrier system. The sound wall barrier system includes a first barrier having a first barrier end including a first recessed cavity, the first recessed cavity defined by an angled side and a recessed back surface; a first elongate post at the first barrier end positioned proximal to the first recessed cavity, the first elongate post including a central web and a post flange coupled to the central web; and a first angled flange coupled to the first barrier within the first recess cavity, wherein the first angled flange and the recessed back surface circumscribe at least a portion of the post flange.

What is claimed is: 
     
         1 . A sound wall barrier system comprising:
 a first barrier having a first barrier end including a first recessed cavity, the first recessed cavity defined by an angled side and a recessed back surface;   a first elongate post at the first barrier end positioned proximal to the first recessed cavity, the first elongate post including a central web and a post flange coupled to the central web; and   a first angled flange coupled to the first barrier within the first recess cavity, wherein the first angled flange and the recessed back surface circumscribe at least a portion of the post flange.   
     
     
         2 . The sound wall barrier system of  claim 1 , wherein the first barrier includes an opposing barrier end opposite the first barrier end, the opposing barrier end having an opposing recessed cavity, wherein the opposing recessed cavity is defined by an angled side and a recessed back surface. 
     
     
         3 . The sound wall barrier system of  claim 2 , comprising:
 a second elongate post at the opposing barrier end positioned proximal to the opposing recessed cavity, the second elongate post positioned substantially parallel to the first elongate post; and   a railing coupled to at least one of the first elongate post and the second elongate post, the railing extending in a direction from the first elongate post to the second elongate post.   
     
     
         4 . The sound wall barrier system of  claim 3 , comprising:
 a set of nested hollow steel sections including an inner hollow steel section and an outer hollow steel section, wherein one of the inner hollow steel section and the outer hollow steel section is coupled to the railing and the other of the inner hollow steel section and the outer hollow steel section is coupled to the first elongate post.   
     
     
         5 . The sound wall barrier system of  claim 4 , wherein the inner hollow steel section and the outer hollow steel section are respectively welded to one of the railing and the first elongate post. 
     
     
         6 . The sound wall barrier system of  claim 3 , wherein the railing is at least one of a hollow steel section or a C-channel beam. 
     
     
         7 . The sound wall barrier system of  claim 3 , comprising:
 a plurality of sound wall panels received between the first elongate post and the second elongate post, wherein the railing is referenced based on a railing plane that is offset to a plane of the plurality of sound wall panels.   
     
     
         8 . The sound wall barrier system of  claim 1 , comprising a footing positioned in a grade, the footing configured to encase the first elongate post. 
     
     
         9 . The sound wall barrier system of  claim 1 , wherein the first angled flange is coupled to the angled side of the first recessed cavity. 
     
     
         10 . The sound wall barrier system of  claim 9 , wherein the first angled flange is coupled to the angled side based on a screw fastener. 
     
     
         11 . The sound wall barrier system of  claim 1 , wherein the portion of the post flange circumscribed by the first angled flange and the recessed back surface is unfixed to the first angled flange and the recessed back surface. 
     
     
         12 . The sound wall barrier system of  claim 1 , comprising:
 a second barrier having a second barrier end positioned adjacent the first barrier, the second barrier having a second recessed cavity, the second recessed cavity defined by an angled side and a recessed back surface, wherein the second barrier end is positioned adjacent the first barrier end to provide a collective recessed cavity,   and wherein the post flange is positioned within the collective recessed cavity.   
     
     
         13 . The sound wall barrier system of  claim 12 , wherein the first barrier includes a first loop protruding from the first barrier end, and wherein the second barrier includes a second loop complementary to the first loop, the second loop protruding from the second barrier end. 
     
     
         14 . The sound wall barrier system of  claim 13 , comprising a fastener configured to be inserted through a combination of aligned first loop and second loop for coupling the first barrier and the second barrier. 
     
     
         15 . The sound wall barrier system of  claim 12 , comprising a second angled flange coupled to the second barrier within the second recessed cavity. 
     
     
         16 . The sound wall barrier system of  claim 1 , wherein the first barrier is a modular concrete barrier. 
     
     
         17 . The sound wall barrier system of  claim 1 , wherein the first angled flange includes a first portion of the first angled flange is configured at approximately 45-degree angle relative to a second portion of the first angled flange.
