Anti-Breach Bollard

Abstract

An anti-breach bollard includes a steel hollow structural section (HSS) member having an interior and a longitudinal axis, and an elongated tubular-shaped structure disposed in the interior and extending generally parallel with the longitudinal axis, the elongated tubular-shaped structure having axially spaced openings.

What is claimed is: 
     
         1 . An anti-breach bollard, comprising:
 a steel hollow structural section (HSS) member having an interior and a longitudinal axis; and   an elongated tubular-shaped structure disposed in the interior and extending generally parallel with the longitudinal axis, the elongated tubular-shaped structure having axially spaced openings.   
     
     
         2 . The anti-breach bollard of  claim 1 , wherein the elongated tubular-shaped structure is constructed of a coiled metal bar. 
     
     
         3 . The anti-breach bollard of  claim 1 , wherein the elongated tubular-shaped structure is constructed of a coiled reinforcement bar. 
     
     
         4 . The anti-breach bollard of  claim 1 , wherein the HSS member has a length between about fifteen feet and twenty feet. 
     
     
         5 . The anti-breach bollard of  claim 1 , wherein the HSS member has a wall thickness of about 0.375 inch. 
     
     
         6 . The anti-breach bollard of  claim 1 , further comprising a grout disposed in the interior, the grout encapsulating at least a portion of the elongated tubular-shaped structure. 
     
     
         7 . The anti-breach bollard of  claim 6 , wherein the grout is a 3,000 psi grout. 
     
     
         8 . The anti-breach bollard of  claim 6 , wherein the grout is a fiber reinforced grout. 
     
     
         9 . The anti-breach bollard of  claim 1 , wherein the HSS member has a length of about fifteen feet to twenty feet and a 6-inch by 6-inch or 8-inch by 8-inch square cross-section; and
 the elongated tubular-shaped structure is a coiled metal bar.   
     
     
         10 . The anti-breach bollard of  claim 9 , further comprising a grout disposed in the interior, the grout encapsulating at least a portion of the elongated tubular-shaped structure. 
     
     
         11 . The anti-breach bollard of  claim 10 , wherein the grout is a fiber reinforced grout. 
     
     
         12 . The anti-breach bollard of  claim 1 , further comprising a grout disposed in the interior, the grout encapsulating at least a portion of the elongated tubular-shaped structure;
 the HSS member having a wall thickness of about 0.375 inch; and   the elongated tubular-shaped structure is a coiled metal bar.   
     
     
         13 . The anti-breach bollard of  claim 12 , wherein the grout is a fiber reinforced grout. 
     
     
         14 . An anti-breach bollard, comprising:
 a steel hollow structural section (HSS) member having an interior; and   an elongated tubular-shaped wire screen disposed in the interior.   
     
     
         15 . The anti-breach bollard of  claim 14 , wherein the elongated tubular-shaped wire screen comprises approximately 2-inch by 2-inch squares. 
     
     
         16 . The anti-breach bollard of  claim 14 , wherein the elongated tubular-shaped wire screen has a wire gauge selected from about 18 gauge to 6/0 gauge. 
     
     
         17 . The anti-breach bollard of  claim 14 , wherein the elongated tubular-shaped wire screen comprises at or about 4-gauge wire and 2-inch by 2-inch squares. 
     
     
         18 . The anti-breach bollard of  claim 14 , further comprising a grout disposed in the interior, the grout encapsulating at least a portion of the elongated tubular-shaped wire screen. 
     
     
         19 . The anti-breach bollard of  claim 18 , wherein the grout is a fiber reinforced grout. 
     
     
         20 . The anti-breach bollard of  claim 14 , further comprising a grout disposed in the interior, the grout encapsulating at least a portion of the elongated tubular-shaped wire screen; and
 the HSS member having a wall thickness of about 0.375 inch.   
     
     
         21 . The anti-breach bollard of  claim 20 , wherein the HSS member has a length of about fifteen feet to twenty feet and a 6-inch by 6-inch or 8-inch by 8-inch square cross-section.
