Locking device of a latticed reinforced member and method for reinforcing a concrete construction using it

Abstract

A locking device of a latticed reinforce member used to the concrete structure includes a spacer and a rivet-type anchor pin, with a groove for inserting reinforcing composite is lengthily formed at the thickness portion of the spacer and a hole for inserting reinforcing composite formed at the center of the spacer, while the anchor pin has a ground plate head formed at its upper portion and the hitting (tension) rod projected at its center and its expansion part at its bottom portion.

What is claimed is:  
     
         1 . Locking device of a latticed reinforce member used to the concrete structure, the said locking device comprising: 
 a spacer  11  has a groove for inserting reinforcing composite  13  lengthily formed along with the thickness portion and a hole for inserting reinforcing composite  15  at center, and;    a rivet-type anchor pin  12  has a ground plate head  16  formed at its upper portion and a hitting (tension) rod  19  projected at its center.    
     
     
         2 . Locking device of a latticed reinforce member as claimed in  claim 1 , wherein the spacer  11  is made of cement mortar, stainless steel, plated metal, plastic, FRP, etc., and the anchor pin is made of stainless steel or plated metal.  
     
     
         3 . Method for reinforcing a concrete structure using the locking device of a latticed reinforce member described in  claim 1 , the method comprising steps of: 
 eliminating laitance and dust on the concrete as well as for water cleaning,    installing the latticed reinforce member on the concrete surface;    drilling the concrete surface with a drill through the hole for inserting anchor pin on a spacer after attaching the spacer at the corner of the reinforce member;    inserting the anchor pin through the above hole for inserting anchor pin on the spacer and hitting (tensioning) the center hitting (tension) rod so as the lower portion of the anchor pin may expand and the hitting (tension) rod may be locked on the concrete surface along with the spacer;    applying the bonding aid on to the concrete surface so as to increase the adhesiveness between the concrete surface and the joint material; and,    filling the joint material up to the upper portion of the locking device.
