Hoop locking device

Abstract

A hoop locking device for locking a hoop installed to surround a plurality of main reinforcements to give a transverse constraint force of the hoop is proposed. The hoop locking device includes: first clips configured to fix opposite ends of hoops, which cross each other while passing by one of the plurality of main reinforcements, each of the first clips comprises: an annular ring formed to surround an overlapping portion of the hoops disposed to vertically overlap each other; a leg part extending radially from opposite ends of the annular ring; and anchor parts formed to be bent rearwards from ends of the leg parts, respectively, and the opposite ends of the hoops are bent by 90 degrees while passing by the main reinforcement.

What is claimed is: 
     
         1 . A hoop locking device for locking an external hoop installed to surround a plurality of main reinforcements on the outside thereof, the hoop locking device comprising:
 first clips configured to fix opposite ends of hoops, which cross each other while passing by one of the plurality of main reinforcements,   wherein each of the first clips comprises:   an annular ring formed to surround an overlapping portion of the hoops disposed to vertically overlap each other;   a leg part extending radially from opposite ends of the annular ring; and   anchor parts formed to be bent rearwards from ends of the leg parts, respectively,   wherein the opposite ends of the hoops are bent by 90 degrees while passing by the main reinforcement, and   wherein the leg part is formed to extend radially long from the opposite ends of the annular ring to be disposed in and fixed to a concrete core.   
     
     
         2 . The hoop locking device  claim 1 , further comprising:
 second clips configured to prevent separation of the first clips from the hoops,   wherein each of the second clips comprises:   an arc-shaped hook coupled to one of the two leg parts;   a stopper configured to be stopped the other of the two leg parts to restrain the other leg part from being widened; and   a connector connecting the arc-shaped hook and the stopper, and   wherein an absorber for extending and contracting the connector is formed in the connector.   
     
     
         3 . The hoop locking device  claim 1 , further comprising:
 fastening clips configured to fasten the hoops to the main reinforcement,   wherein each of the fastening clips comprises:   a first fastening hook formed to surround the main reinforcement;   a second fastening hook extending from the first fastening hook and formed to surround the hoop; and   a third fastening hook extending from the second fastening hook, and   wherein an absorber for easy deformation of the first fastening hook is formed in the first fastening hook.   
     
     
         4 . The hoop locking device  claim 3 , wherein each of the hoops comprises linear portions and a corner portion, and
 wherein each of the fastening clip comprises flat shapes installed in the linear portions and a corner shape installed in the corner portion.   
     
     
         5 . The hoop locking device  claim 3 , wherein the third fastening hook stops a tool for pulling the first fastening hook and the second fastening hook, such that the main reinforcement and the hoop are attached to each other by the first fastening hoop and the second fastening hoop. 
     
     
         6 . The hoop locking device  claim 3 , wherein the first fastening hook is formed to be open toward the outside,
 wherein the second fastening hook is formed to be bent downwards from opposite ends of the first fastening hook so as to be opened toward the inner side, and   wherein the third fastening hook is bent downwards from the second fastening hook to be opened toward the outside.
