The present invention relates to a reinforcing bar connection device. More specifically, a tapered hole of a coupler that directly presses the reinforcing bar by shaking or external impact when joining a reinforcing bar of a certain length that provides a tensile force to a concrete structure. The present invention relates to a reinforcing bar joint device which can be secured to secure the joint coupling so as not to deviate from.

In general, reinforced concrete is composed by combining the strengths and weaknesses of reinforcing bars and concretes to complement each other, and the resistance to tensile stress, that is, the tensile strength is weak compared to the compressive and compressive strengths of concrete, so that it is cracked even with slight tensile stress. This occurs and is destroyed.

In order to reinforce the shortcomings of concrete, the reinforced concrete structure is arranged with reinforcing bars in the part where the tensile stress of the concrete acts.In case of external force, the compressive stress is applied to the concrete and the tensile stress is applied to the reinforcing bars. It is a structure constructed to resist.

In the production method of such reinforced concrete, the reinforcement process, which is the most basic process of construction, is an important process for determining the life and stability of the reinforced concrete.

In this case, the length of the reinforcing bars in the concrete is also extended due to the increase in size and height of the reinforced concrete structure.In the case of reinforcing bars, the joint is connected to each other because the length of the reinforcing bars is limited to the standard products. It is becoming.

Reinforcing bar method as described above is mainly folds. Gas welding joints and mechanical joints are used. In particular, the mechanical joint method of connecting reinforcing bars without mechanical or physical changes to the shape of the reinforcing bars absorbs static and dynamic loads sufficiently to ensure durability of the reinforcing concrete structures. It is a connecting device to ensure stable construction.

As shown in FIG. 1 or 2, the conventional reinforcing bar connection device as described above is provided with a pair to form a plurality of nodular grooves 12b on the inner circumference and a male thread 12a on both sides of the outer circumference. It consists of a sphere 12 and a sleeve coupling 11 formed with a female screw 11a on the inner circumference and a through hole 11b in the center portion so as to be screwed to the outer circumference of both sides of the binding sphere 12. .

The joint structure of the reinforcing bar connection device 10 is connected to both the reinforcing bars (1) formed a plurality of projections (1a) on the outer periphery and then the joint portion is located in the inner peripheral center portion of the binding hole 12 Thus, the pair of fasteners 12 are temporarily coupled to the reinforcing bar 1 so that the nodal protrusion 1a of the reinforcing bar 1 can be fitted into the nodular groove 12b.

Thereafter, the through-hole 11b of the sleeve coupling 11 passes through the reinforcing bar 1, and the sleeve coupling 11 is coupled to the male screw 12a formed on both sides of the binding hole 12 by screwing. Reinforcing the reinforcing bars (1) by coupling a pair of fasteners (12) integrally coupled to the reinforcing bars (1).

However, the reinforcing bar connection device 10 according to the prior art does not cut both ends of the reinforcing bar 1 when the two ends of the reinforcing bar (1) to be jointly coupled to the exact dimensions do not come in close contact with the reinforcing bar ( Due to the problem that 1) is shaken and the rebar 1 is finely moved inside the connecting device 10, there is a problem that the compression and bending intervals of the reinforcing bar are weak.

As a result, as the stiffness of the reinforcing bar 1 is deteriorated, there is a problem in that the seismic resistance of the reinforced concrete structure is weakened by reducing the stiffness and deformation of the reinforced concrete structure.

Therefore, the main object of the present invention is to enable the combination of a plurality of incisions strongly pressing the outer periphery of the reinforcement in the joint device for connecting the reinforcing bars to maintain the fixed state of the reinforcement and the incision by the elastic force This is to make it possible to connect the joint state of the reinforcing bar more closely.

In addition, another object of the present invention is to ensure that the cut piece that directly presses the rebar by shaking or external impact when joining the reinforcing bar of a certain length of the standard product providing a tensile force to the concrete structure is not separated from the taper hole of the coupler It is to ensure the robustness of the joint connection.

In order to achieve the above object, the reinforcing bar joint device of the present invention is formed in a plurality of arc shapes to form a plurality of nodular grooves on the inner circumference, the outer circumference is formed to be tapered, and the coupling groove is formed to the rear to integrally combine the reinforcing bars An incision piece coupled to the outer circumference of the pair, and a pair of joints each having a tapered hole formed therein so as to couple the combined incision therein and a female screw hole and a male screw hole respectively formed to communicate with the rear part; Coupling couplers formed with male and female threads on both sides of the outer periphery of the outer periphery so as to be coupled to the female and male threads of the joint, and a communication hole penetrates the inner center thereof, and the coupling grooves for integrating the plurality of cut pieces. The jaw is formed to bend the contact surface to be in close contact with the rear end surface of the incision while forming a locking step on one side to be inserted Characterized in that the member, such that the intergranular squeezed between the two side ends of the coupling coupler and the rear portion of the combination member composed of a spring that allows the pressure on the combination member may be cut in a tapered side pressure inside the ball.
