Beam for a vehicle barrier

Abstract

A beam for connecting between posts in a vehicle barrier includes a steel beam having a web and opposing flanges extending perpendicular to the web, a first plate extending beyond a left end of the beam, a first hole penetrating the first plate beyond the left end, a second plate extending beyond a right end of the beam, and a second hole penetrating the second plate beyond the right end.

         2 . The beam of  claim 1 , wherein the first plate and the second plate are horizontal with the web. 
     
     
         3 . The beam of  claim 1 , wherein the first plate comprises:
 a beam portion overlapping the web; and   an extension portion extending beyond the left end of the beam.   
     
     
         4 . The beam of  claim 1 , wherein the first hole and the second hole are perpendicular to the web. 
     
     
         5 . The beam of  claim 1 , wherein the first plate and the second plate are located on opposite sides of the web. 
     
     
         6 . The beam of  claim 1 , wherein the first plate and the second plate are located on a same side of the web. 
     
     
         7 . The beam of  claim 1 , wherein:
 the first plate and the second plate are horizontal with the web;   the first hole and the second hole are perpendicular to the web; and   the first plate comprises a beam portion overlapping the web and an extension portion extending beyond the left end; and   the second plate comprises a beam portion overlapping the web and an extension portion located beyond the right end.   
     
     
         8 . The beam of  claim 7 , wherein the first plate and the second plate are located on opposite sides of the web. 
     
     
         9 . The beam of  claim 7 , wherein the first plate and the second plate are located on a same side of the web. 
     
     
         10 . A beam for connecting between posts in a vehicle barrier, the beam comprising:
 a steel beam having opposing flanges extending perpendicular to a web;   a first top plate extending beyond a left end of the beam;   a first bottom plate extending beyond the left end parallel to the first top plate;   a first top hole penetrating the first top plate;   a first bottom hole penetrating the first bottom plate coaxial with the first top hole;   a second top plate beyond a right end of the beam; and   a second top hole penetrating the second top plate beyond the right end.   
     
     
         11 . The beam of  claim 10 , wherein the first top hole and the second top hole are perpendicular to the web. 
     
     
         12 . The beam of  claim 10 , wherein the first top plate and the first bottom plate are located on opposite sides of the web. 
     
     
         13 . The beam of  claim 10 , wherein the first top plate, the first bottom plate, and the second top plate are parallel to the web. 
     
     
         14 . The beam of  claim 10 , wherein the first top plate and the first bottom plate each comprise a beam portion overlapping the web and an extension portion extending beyond the left end of the beam. 
     
     
         15 . The beam of  claim 10 , wherein the first top plate and the first bottom plate are located on opposite sides of the web; and
 the first top plate, the first bottom plate, and the second top plate are parallel to the web.   
     
     
         16 . A beam for connecting between posts in a vehicle barrier, the beam comprising:
 a steel beam having opposing flanges extending perpendicular to a web;   a first top plate extending beyond a left end of the beam;   a first bottom plate extending beyond the left end parallel to the first top plate;   a first top hole penetrating the first top plate;   a first bottom hole penetrating the first bottom plate coaxial with the first top hole;   a second top plate extending beyond a right end of the beam;   a second top hole penetrating the second top plate beyond the right end;   a second bottom plate extending beyond the right end of the beam; and   a second bottom hole penetrating the second bottom plate coaxial with the second top hole.   
     
     
         17 . The beam of  claim 16 , wherein the first top hole and the second top hole are perpendicular to the web. 
     
     
         18 . The beam of  claim 16 , wherein:
 the first top plate and the first bottom plate are located on opposite sides of the web; and   the second top plate and the second bottom plate are located on opposite sides of the web.   
     
     
         19 . The beam of  claim 16 , wherein:
 each of the first top plate and the first bottom plate comprise a beam portion overlapping the web and an extension portion extending beyond the left end; and   each of the second top plate and the second bottom plate comprise a beam portion overlapping the web and an extension portion extending beyond the right end.
