Bumping post block and anchor holder and hole cap used for the same and bumping post

Abstract

An anchor bolt bolt does not easily jump up even if a tire hits a bumping post. A through hole for inserting the anchor bolt into the bumping post is formed by embedding a cylindrical anchor holder. The anchor holder has a cylinder for receiving the anchor bolt and a head for containing the head of the anchor bolt. A plurality of projecting parts, forming a protruding line, prevent the head of the anchor bolt from jumping up. The projecting parts are positioned at the head of the holder. Since the head of the bolt is pressed down from above by the protruding line, the head of the bolt will not jump up over the projecting parts.

1 . A concrete curb block comprising: 
 a concrete curb block body having a through hole oriented in a vertical direction for receiving an anchor bolt to fix said concrete curb block body to an installation surface;    a concave portion formed in an upper surface of said concrete curb block body;    a hole cap fitted into said concave portion such that said upper surface of said concrete curb block body and an upper surface of said hole cap form a flat surface; and    a reflector disposed at a front portion of said hole cap such that said reflector is exposed to a front side of said concrete curb block body.    
   
   
       2 . The concrete curb block as claimed in  claim 1 , further comprising an anchor holder inserted in said through hole, 
 wherein said hole cap is mounted on an upper part of the through hole, said upper surface of said hole cap has a shape of a plane, and said hole cap includes a cylindrical foot part, and    wherein said anchor holder comprises a generally cylindrical portion for receiving a shank of the anchor bolt, and a head portion positioned at an upper end of the cylindrical portion for containing a head of the anchor bolt, said head portion having a plurality of projecting parts for overlying an upper surface of the head of the anchor bolt when inserted therein.    
   
   
       3 . The concrete curb block as claimed in  claim 1 , further comprising: 
 at least one insert for receiving an auxiliary anchor, said at least one insert being embedded in a base portion of said concrete curb block body.    
   
   
       4 . A hole cap capable of being mounted on an upper part of a vertical through-hole provided in a concrete curb block, said hole cap comprising: 
 a flat upper surface having a shape of a plane;    a front part provided with a reflector; and    a cylindrical foot part.
