Supporting bolt and supporting system for raised access floor with the same

Abstract

The present invention provides a supporting bolt, and a supporting system for a raised access floor with the same, having advantages of improved fluidity of an adhesive. The supporting bolt for a supporting system for a raised access floor includes a bolt body having a screw thread for combining with a nut on an exterior surface thereof, a central penetration hole in which an adhesive flows along a length direction of the bolt body, and an air hole communicating with the central penetration hole.

1 . A supporting bolt for a supporting system for a raised access floor, wherein the supporting system is installed between a slab and a floor panel so as to support the floor panel by using the supporting bolt and a nut for leveling, the supporting bolt comprising: 
 a bolt body having a screw thread for combining with the nut on an exterior surface thereof;    a central penetration hole in which an adhesive flows along a length direction of the bolt body; and    an air hole communicating with the central penetration hole.    
   
   
       2 . The supporting bolt for a supporting system for a raised access floor of  claim 1 , wherein the air hole is formed at the screw thread of the bolt body, and there is at least one air hole.  
   
   
       3 . The supporting bolt for a supporting system for a raised access floor of  claim 2 , wherein the air hole is formed to communicate perpendicularly with the central penetration hole.  
   
   
       4 . The supporting bolt for a supporting system for a raised access floor of  claim 2 , wherein the air hole forms an acute angle with the central penetration hole with respect to the floor panel.  
   
   
       5 . The supporting bolt for a supporting system for a raised access floor of  claim 1 , wherein an engagement groove for a screwing tool is formed at an end portion of the supporting bolt.  
   
   
       6 . A supporting system for a raised access floor, wherein the supporting system is installed between a slab and a floor panel so as to support the floor panel, comprising: 
 a supporting bolt comprising a bolt body having a screw thread, a central penetration hole formed along a length direction of the bolt body wherein an adhesive flows, and an air hole communicating with the central penetration hole;    a supporting plate for supporting the floor panel;    a nut that is located at the supporting plate and is formed so as to combine with the screw thread of the supporting bolt; and    an anti-vibration unit that is combined with a head portion of the supporting bolt and is located on the slab.    
   
   
       7 . The supporting system for a raised access floor of  claim 6 , wherein the anti-vibration unit comprises: 
 a body having a hemisphere-shaped lower surface that is located over the slab;    a penetration hole that is located in the middle portion of the body of the anti-vibration unit so as to communicate with the central penetration hole of the supporting bolt; and    a skirt unit that protrudes from the hemisphere-shaped lower surface and surrounds the penetration hole, the skirt unit supporting the body of the anti-vibration unit with a predetermined height so as to acquire a space for adhesion between the body and the slab.    
   
   
       8 . The supporting system for a raised access floor of  claim 7 , wherein the diameter of the penetration hole is larger than that of the central penetration hole of the supporting bolt.  
   
   
       9 . The supporting system for a raised access floor of  claim 7 , wherein each of the body of the anti-vibration unit and the skirt unit is made of an anti-vibration rubber or an elastic rubber.  
   
   
       10 . The supporting system for a raised access floor of  claim 7 , wherein the skirt unit comprises an adhesive-exhausting portion.  
   
   
       11 . The supporting system for a raised access floor of  claim 6 , wherein the supporting plate has a receiving portion for receiving an adhesive.
