REINFORCING ROD A COUPLING DEVICE

摘要

The present invention relates to a reinforcing bar connection device. More specifically, both side end parts of each reinforcing bar to be connected are easily inserted and fastened when the reinforcing bars used for constructing a reinforced concrete structure are connected to each other. Moreover, the present invention prevents the reinforcing bar from being loosened from a connector although external vibration is occurred wince both side end parts of the connector closely tighten an outer circumferential portion of the reinforcing bar. The reinforcing bar connection device connecting two reinforcing bars wherein a male screw unit is formed on an outer circumferential surface with a connection means. The connection means comprises: a connection pipe body of which both sides are opened and having a spiral hole where the female screw unit is formed on the inner circumferential surface; a mounting groove having a wider inner diameter than the spiral hole toward the inside of both end surfaces of the connection pipe body; and a loosening prevention unit positioned inside the mounting groove to hold the outer circumferential surface of the reinforcing bar to prevent loosening.
