The present invention relates to a reinforcing bar when constructing a reinforced concrete structure by using a one-touch reinforcing bar connection device formed of a coupler and a fixed washer more easily and simply, thereby improving the workability by reducing the number of work steps, It relates to a one-touch rebar joint device to strengthen the tensile strength is an improvement of the patent application 10-2003-0078940 'rebar joint device' that the present inventor has filed.

Reinforced concrete is a combination of reinforcing steel and concrete, and the concrete bears the compressive force and the steel bears the tensile force. Reinforced concrete structure is installed as a form after reinforcing the reinforcement, and concrete is installed in this way.In the process of construction, the reinforcing bar must be connected to each other with a certain length as needed. Will occur. In the joint portion formed between the reinforcing bars and the reinforcing bar is a predetermined tensile force generated during the curing process of concrete. In order to sufficiently cope with such a tensile force, a close connection state between the bars must be maintained, and a method such as overlapping joint or pressure welding is generally applied thereto.

Overlap joint is a method of reinforcing reinforcing bars and reinforcing bars over the length of the required joint and placing them in a binding line. This has the advantage of easy reinforcement work, but when the diameter of the reinforcing bar is large, the stress concentration of the reinforcing bar is not matched by the eccentricity, and there is a problem in the structural strength, and when the concrete member is thin, the cross section of the formwork is narrowed due to the overlapping reinforcing concrete. It is not easy to pour and there is a problem that it is difficult to maintain the reinforcement spacing of the rebar and the minimum coating thickness of the concrete.

In addition, the method of connecting the reinforcing bars by pressure welding is a method in which the ends of the reinforcing bars and the reinforcing bars are successively joined together, and then heated and pressed to integrally form the ends. The pressure welding is a long working time and the heat is directly applied to the rebar, the properties of the iron is changed, the strength of the heat is reduced or strengthened according to the speed of the bending and eccentricity has a lot of problems, it is not easy to apply it.

In order to solve the problems caused in the reinforcing bar joint method by the overlap joint and the pressure welding, a conventional reinforcing bar connection method for mechanically connecting the reinforcing bar and the rebar has been used.

Figure 1a is an exploded perspective view showing an embodiment of a conventional reinforcing bar fittings, Figure 1b is a cross-sectional view of the coupling of the conventional reinforcing bar fitting according to Figure 1a.

As shown in Figures 1a and 1b, the conventional reinforcing bar coupling device is composed of a coupler (10) and a nut (6) fastened to both sides thereof. Coupler 10 has a cylindrical structure as a whole, it is divided into a central body portion 1 and the locking portion (2) located at both ends thereof.

The inner circumferential surface of the body portion 1 is formed with a female screw 3 to which the reinforcing bars 11 are fastened, thereby screwing the threaded portion 7 formed at the end of the reinforcing bar 11 to the female screw 3 so as to provide two reinforcing bars 11. ) Can be connected to each other.

The inner diameter d1 of the locking part 2 is larger than the inner diameter d2 of the body part 1, and becomes thinner and taper toward the end, and the nut 10 is formed on the outer circumferential surface thereof. The male screw 4 in which the screw is screwed is formed. In addition, a plurality of cutout grooves 5 are formed in the circumferential surface of the locking part 2 along the longitudinal direction thereof so as to be tightened in the inner diameter direction when the nut 10 is fastened.

Looking at the reinforcing bar connection process using the conventional reinforcing bar connection device, first begins by cutting the end of each of the reinforcing bar 11 to be connected to form a screw portion 7 of a predetermined diameter. When the threaded portion 7 is formed on each of the reinforcing bars 11, the two reinforcing bars 11 are aligned in a line such that the threaded portions 7 face each other, and then the reinforcing bars are inwardly turned on both sides of the coupler 10. While fitting, each screw 7 is fastened to the female screw 3 inside the coupler 10. Subsequently, when the nut 10 is fastened and tightened to the male screw 4 on the surface of the locking portion 2, the inner diameter of the locking portion 2 contracts and the node 8 and the node and rib 9 on the surface of the reinforcing bar 11 are tightened. Pressed so that the two reinforcing bars 11 are connected to each other.

However, such a conventional reinforcing bar coupling device has to form a screw portion by cutting the end of the rebar, the number of processes for the reinforcing bars increases not only to reduce the work efficiency, but also has a problem that the structure is complicated and not easy to manufacture.
