{COUPLER FOR STEEL BAR}

The present invention relates to a one-touch reinforced bar coupler, and more particularly, to a reinforced bar one-touch coupler capable of easily connecting and fixing two reinforcing bars by inserting a reinforcing bar into a coupler and fixing the reinforcing bar to the coupler.

In order to connect reinforcing bars for use in concrete structures in various construction sites, conventionally, reinforcing bars have been double-layered and fixed with wires or the like, but these reinforcing bar fixing methods require the operator to bundle the wires after winding them. The center of gravity is not vertical but is distorted and the strength of the wire is weak so that it is easily broken and the connection state is released.

A one-touch reinforcing bar coupler that links reinforcing bars to each other has been widely used in construction sites. In this prior art, registration number 10-1039120 filed in the Korean Intellectual Property Office, registration number 10-0439305, registration number 10-1036591.

1 is a sectional view showing a conventional reinforcing coupler.

As shown in FIG. 1, a typical coupler includes a coupler body coupled to be opposed to each other, and an internal coupler coupled to the coupler through a wedge surface. In the conventional coupler, the coupling force through wedge action is weakened The elastic spring 40 is used.

However, the conventional one-touch one-touch coupler can provide sufficient strength for tensile force, but fails to provide a sufficient fastening force when a bending load is applied. Further, in the process of inserting the reinforcing coupler, The inner diameter of the member is narrowed, which makes it difficult to insert the reinforcing bar.
