Description

One-touch rebar coupler {Steel Connecting coupler}

The present invention relates to a one-touch type reinforcing bar coupler, and more particularly, by inserting the ends of both ends of two reinforcing bars to be easily connected, it provides a binding force capable of preventing loosening due to vibration and impact and deformation due to load. Eggplant relates to a one-touch rebar coupler.

In various construction sites, the shape and number of reinforcing bars used to form the frame of a concrete structure are determined according to the shape and length (height) of the concrete structure.

These reinforcing bars are standardized products having a certain length and diameter, and a number of them are supplied as a bundle, and they are cut to the required length or height at the construction site, and a plurality of rebars are tied and fixed using wires.

However, the wire fixing method requires a lot of time because the worker must do it manually, and there is a problem that the reinforcing bar is not placed on the same straight line but is inclined to one side, and the part bound by the wire is weak. There was a problem that it was easily released.

In addition, the more you go up to the higher floors, the more difficult it is to work, the more dangerous situations arise, and it is a reality that requires more personnel.

In order to solve this problem, a “rebar jointing device” has been proposed as a technique previously proposed.

In the prior art, a pair of incision pieces are combined with both reinforcing bars to be jointed and inserted into the inner periphery of the taper hole of the coupling coupler and the coupling coupler, which are screwed together, so that the ends of both rebars are screwed together. It is made to minimize the strain for static and dynamic loads of concrete structures by improving the stiffness against compression and bending of the reinforcing bars by making them in close contact so that the reinforcing bars can be jointed without shaking.

However, in the prior art, it is difficult to connect both reinforcing bars as they are fixed through screwing in a state that is coupled to the ends of both reinforcing bars, and there is a problem that a lot of time is required because pre-work is required.

In addition, since the reinforcing bar is not arranged in the center, there is a problem that it is difficult to easily combine the reinforcing bar due to the load and shaking of the rebar.
