Bollard System and Method of Installation

Abstract

An anti-ram bollard assembly ( 1 ) and an installation of the same to arrest impacts are provided. The bollard assembly includes a base assembly ( 20 ), a bollard member ( 10 ) attached to the base assembly and at least one reinforcement member ( 32 ) attached to the base assembly. The base assembly may include an I-beam arrangement to provide increased strength of the base assembly. Several bollard assemblies may be connected to form a cohesive installation to achieve a high impact rating. To this purpose, rebars ( 104 ) may be provided to connect the base assemblies of adjacent bollard assemblies. Further, the bollard member may be provided as a hollow member and may be subsequently filled with a high-strength material to prevent failure of the bollard member when it is being struck.

 a bollard member attached to the base assembly; 
 a first reinforcement member attached to the base assembly to enlarge the base area; and 
   a plurality of rebars connecting the plurality of bollard assemblies.   
   
   
       14 . The installation of  claim 13 , wherein the first reinforcement member includes a free end spaced apart from an adjacent one of the plurality of bollard assemblies. 
   
   
       15 . The installation of  claim 14 , wherein the I-beam arrangement comprises:
 a top plate;   a bottom plate; and   an intermediate plate supporting the top plate and the bottom plate, wherein the top plate, the bottom plate and the intermediate plate are attached to the bollard member.   
   
   
       16 . The installation of  claim 15 , wherein the intermediate plate is perforated to receive the plurality of rebars there through. 
   
   
       17 . The installation of  claim 15 , wherein a first side of the base assembly is to receive an impact and the first reinforcement member is disposed on a second opposed side of the base assembly.
