Title:
APPARATUS FOR COUPLING REINFORCING BAR USING HYDRAULIC PRESSURE
Document Type and Number:
WIPO Patent Application WO/2015/030342
Kind Code:
A1
Abstract:
Disclosed is a coupling apparatus which presses a conical member having a curved side surface in a direction perpendicular to a reinforcing bar using hydraulic pressure, thereby considerably reducing working time for a reinforcing bar coupling, completely securing a reinforcing bar, and increasing compressive and bending strength. It is possible to stably carry force from the conical member through an external force dispersion medium member to a reinforcing bar securing member. Accordingly, there is a structural advantage of effectively preventing displacement of a reinforcing bar and loosening of a reinforcing bar coupling.
