REINFORCING BAR COUPLER AND A PRECAST CONCRETE ASSEMBLY UNIT USING THE SAME, CAPABLE OF REDUCING CONSTRUCTION ERRORS IN AN INSTALLING PROCESS

摘要

PURPOSE: A reinforcing bar coupler and a precast concrete assembly unit using the same are provided to allow a user to easily perform a connection work and to be connected when connecting reinforcing bars are not on the same axle and is crossed within a predetermined range.;CONSTITUTION: A reinforcing bar coupler(100) comprises a male coupler(110), a coupler guide unit(120), and a female coupler(130). The male coupler is formed at an end of a first connecting reinforcing bar(11), the coupler guide unit is formed at the end of a second connection reinforcing bar(12). The female coupler is movably installed at the coupler guide unit, and a stopper(160) prevents separation. A hole and a movement guide hole are formed inside the female coupler, and the female coupler is formed inside the hollow. Construction errors are reduced by diameter differences of the movement guide hole and the coupler guide unit.;COPYRIGHT KIPO 2013
