Modular exterior casing for crash barriers made of glass fiber reinforced concrete

Abstract

A modular exterior casing for crash barriers made of glass fiber reinforced concrete that is pre-engineered and pre-finished, preferably lightweight and can be placed manually to cover existing concrete barriers. The exterior casing consist of lateral and longitudinal wall segments wherein said wall segments include a plurality of three-dimensional shapes comprising of lumps and recessed walls that are slightly sloped preferably oblique to the base. The wall segments are pre-engineered composite cement mix and graded stone with long strands of glass fibers randomly dispersed and laid in all directions within the interior matrix surrounding the lateral and longitudinal walls.

I claim:  
     
         1 . A modular exterior casing for crash barriers comprising of: 
 2. pre-engineered and pre-finished enclosure shells    3. made of composite cement and graded stone embedded with strands of glass fibers.    
     
     
         4 . The enclosure shells of claim  2  wherein said shells consist of lateral and longitudinal casing components divided into lateral and longitudinal wall segments.  
     
     
         5 . the lateral and longitudinal wall segments of  claim 4  wherein said wall segments are pre-finished to include a three-dimensional shape consisting of a top lip radius, upper recessed wall, upper-mid lump, lower-mid lump, base lump, lower recessed wall and base recessed wall.  
     
     
         6 . the wall segments of  claim 4  wherein said lateral and longitudinal wall segments are slightly sloped tapering preferably 75 to 85 degrees oblique to the base recessed wall.  
     
     
         7 . the wall segments of  claim 4  wherein said lateral and longitudinal wall segments are attached to an existing concrete barrier by means of metal loop anchors and grade steel wires. While the wall base footing is attached to the earth by means of metal pin dowels.  
     
     
         8 . the wall segments of  claim 4  wherein the said lateral and longitudinal wall segments creates an opening between the wall segments and the existing concrete barrier intended for back fill of graded soil or planting medium thereby creating a planting compartment.  
     
     
         9 . The modular exterior casing in  claim 1  and  3  wherein said exterior casing is pre-engineered to contain long strands of glass fibers randomly dispersed and laid in all directions within the interior matrix surrounding the lateral and longitudinal walls.
