Rebar connector having a pair of locking pieces and connection method for prefabricated rebar net using same

Abstract

Disclosed is a rebar connector having a pair of locking pieces, comprising: a first rebar and a second rebar that are to be connected such that end portions thereof face each other; a first connecting member having an empty space formed therein, wherein the first rebar is coupled to the empty space through one side thereof, a first coupling hole is formed at an opposite side thereof, and an external fastening thread is formed on a predetermined section of the outer surface thereof; a second connecting member having an empty space formed therein, wherein the second rebar is coupled to the empty space thereof through one side thereof, and a second coupling hole is formed at an opposite side thereof; a first locking piece that is separately provided and is coupled to the first coupling hole; a second locking piece that is separately provided and is coupled to the second coupling hole; and a locking socket that is coupled to surround the outer surface of the second connecting member after being stopped by a predetermined location of the second connecting member and has an internal fastening thread that is formed on a predetermined section of the inner surface thereof and is fastened to the external fastening thread of the first connecting member, wherein the pair of first and second locking pieces are integrated by fastening the locking socket to form a connection part while making contact with each other.

Description

technical field [0001] The invention relates to a steel bar joint equipped with a pair of locking blocks, especially a joint that can be applied to the joint of single steel bars and the combination of steel tendons of prefabricated steel mesh, and can eliminate the initial sliding phenomenon of the joint joint from the source. It is a steel bar joint that can connect and join while correcting the inclination of the prefabricated steel mesh on one side without filling grout material. Background technique [0002] Existing Japanese Patent Laid-Open No. 6-157873 discloses a bar steel threaded joint, specifically a kind of threaded joint that can be formed by providing a male thread at the connecting end of a pair of bar steel that needs to be connected and utilizing the inner peripheral surface to form a threaded joint. The threaded joint of the bar steel that connects the above-mentioned pair of bar steel with the female thread coupler that realizes the thread combination wit...

AI Technical Summary

Problems solved by technology

At this time, if a bend is formed at the end of each steel bar or a burr or a sharp point is formed during the cutting process, it will cause the above-mentioned problem that the thread of the coupler is stuck, and the phase difference of the thread is also difficult to absorb

At the same time, even the prefabricated steel mesh assembled with precise jigs will deform due to its own weight during the transfer process, resulting in dimensional errors at the end. Therefore, the end of the steel bar inserted into the above-mentioned coupling is checked The process of axis alignment will be very difficult

[0014] And even after the hard shaft alignment, existing couplings cannot be secured by rotational lift or rotational descent of this loose coupling because the clearance length in the axial direction of the existing coupling is greater than one-half the thread pitch. The verticality of the prefabricated steel mesh with unreliable connections, and there is no other effective verticality guarantee operation method

[0015] Therefore, in the case where the verticality of the prefabricated steel mesh composed of column steel bars cannot be guaranteed, the beam bars fixed to the above column bar bars and the wall bars fixed to the beam bars cannot be accurately fixed.
