In general, concrete is a composite composition in which cement, sand, gravel, water, etc. are mixed at a suitable ratio, and the compressive strength is relatively high, but the tensile strength is very low compared to the compressive strength, and has a property of easily cracking. In order to increase the tensile strength of the concrete, it is installed by binding the reinforcing bars in the formwork where concrete is poured, and then placing concrete to reinforce the strength of the concrete. This conventional reinforced concrete structure is excellent in compression and tensile strength, and can be used to construct various types of structures, as well as its physical properties are widely used in various construction and civil works. Deformed reinforcing bar refers to a node formed on the surface of the reinforcing bar, and generally, an axial node is referred to as a 'rib' and a circumferential node is referred to as a 'node'.

In order to install the formwork in which concrete is cast in the prior art, the reinforcement work is arranged to arrange the deformed reinforcing bars in a predetermined form. Necessary, such a conventional method of connecting the reinforcing bar has been proposed, such as lap joint method, welding joint method, screw joint method, connecting device joint method.

The lap joint method is a method of winding wires at the ends of overlapping rebars, which has the advantage that the reinforcement work is relatively easy. Due to its weakness, safety problems have been pointed out. On the other hand, the welding joint method is a method of welding the ends of the deformed rebars to each other, the strength of the connection portion is good, there is no problem, but the work is very cumbersome and takes a lot of time, the construction is delayed. Screw joint method is a method of connecting the interconnection by processing the screw at the connecting end of the deformed reinforcing bar requires a facility for processing the connecting end, there is a problem that the construction is not possible in a narrow space, and the connecting device joint method is a connecting device As a method of interconnecting both ends of the deformed reinforcement using the prior art, the conventional prior art had a problem that the deformed reinforcement of the interior of the connecting device is shaken to reduce the tensile force of the reinforced concrete, constituting the connecting device Due to the large number of parts and the complicated structure, the cost was high due to the production of the product, and there was a problem in that the construction was delayed as well as the labor cost was increased due to the time required for the work.

The present invention has been made to solve the above problems, the number of parts constituting the connection device is simple and the structure can be significantly reduced the cost according to the product production, rebar connection can be carried out quickly and simply, It is to provide a one-touch rebar connecting device that can reduce the construction cost with high construction.
