Abstract

PURPOSE: A rebar connector is provided to remove risk of separation and movement of rebars and enable rapid work since it is convenient to connect rebars. CONSTITUTION: A rebar connector comprises a support rod(1), connecting pipes(2,3), an extendable conning unit(4) and a coil spring(5). A male screw(1a) is formed on the outer surface of the support rod. The connecting pipes are screwed to both ends of the support rod. The connecting pipe comprises female screws(2a,3a), which are on a cylinder form of a coupling unit. Openings(2b,3b) are formed on the other side of the connecting pipe. The opening is tapered. The inner surface of the connecting pipe is formed in a polygonal slope(4c). The extendable connecting unit is held in the connecting pipe.

Description

Reinforcing rod jointer

The present invention relates to a reinforcing bar connector, and more specifically, a connector used to connect reinforcing bars and reinforcing bars in the longitudinal direction. One rebar connector.

Conventionally, reinforcing connectors of various configurations have been developed, including one-touch reinforcing connector, but the configuration is often complicated and inconvenient to use.

The present invention has been developed in order to solve the above conventional drawbacks, and the object of the present invention is that the reinforcing bar connector can be tightly fixed so that the rebar connection work is convenient and there is no risk of detachment and fluidity after the connection, and easy dismantling when necessary. To provide.

In order to achieve the above object, the present invention provides a support rod (1) formed with an external thread (1a) on the outer surface;
Screws are assembled at both ends of the support rod (1) and are provided with female threads (2a) and (3a) at the engaging portions of the cylindrical body, and openings (2b, 3b) having a wide inner side and a narrow outer side are formed on the opposite side to form a polygonal inclined guide surface ( Connecting pipes 2 and 3 formed of 4c);
Polygonal guide surface 4c, which is accommodated in the inner surface of the connecting pipes 2 and 3, is made of semi-solid, and has reinforcing bar receiving grooves 4a and 4b formed therein, and the outer surface thereof is the same as the polygonal inclined guide surface 4c of the connecting pipes 2 and 3; A telescopic splicer (4);
Reinforcing bars composed of coil springs 5 interposed between the telescopic connectors 4 and the support rods 1 to close the telescopic connectors 4 toward the openings 2b and 3b of the connecting pipes 2 and 3. In the connector,
The supporting rod 1 is formed of a metal round rod, and protruding rods 1b and 1c are formed on both sides of the central portion, and a perforated hole 1d is formed on the outer circumferential surface thereof.

The present invention is not only possible to perform a quick operation of the reinforcing bar connection work, but also can be tightly fixed so that there is no risk of separation and fluidity after connecting the reinforcing bar, and easy to dismantle when necessary has the effect of improving the work efficiency.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
It is to be noted that like elements in the accompanying drawings use the same reference numerals in any of the drawings, and detailed descriptions of well-known functions or known configurations that may unnecessarily obscure the gist of the present invention are omitted. Come on.

According to the present invention as described above, female screw portions 2a and 3a of the connecting pipes 2 and 3 are screw-assembled at both ends of the support rod 1 of the reinforcing bar connector.
In addition, the openings 2b and 3b of the connecting pipes 2 and 3 have an inclined surface having a wide inner side and a reduced outer side to have a polygonal surface, which is half-divided therein, and reinforcing grooves 4a and 4b are formed on the inner surface. And an elastic connector 4 provided with a polygonal guide surface 4c whose outer surface is an inclined surface having a large inner diameter and a small outer diameter.
Therefore, it is pushed toward the openings 2b and 3b of the connection pipes 2 and 3 by the coil spring 5 installed therein, and thus slides under elasticity. When the rebar end is inserted into the retractable connector 4, which has been moved at the end of the opening part 2b of the connector 2, it is pushed inward by the rebar, so that the retractable connector is relaxed and opened, and the rebar is inserted therebetween. When contacting the protruding bar (1b) formed on both sides of the support bar (1), the longitudinal projection (6a) of the reinforcing bar is coupled to the longitudinal reinforcing groove (4a) of the telescopic connector (4) and the transverse projection chamber (6b) of the rebar ) Is made to be coupled to the horizontal rebar receiving groove (4b) of the stretchable connector (4).
In this state, the coil spring 5 moves toward the opening 2b by the elasticity of the coil spring 5, and at this time, the wrench 7 is inserted into the hole 1d in the middle of the supporting rod 1 When rotated, the male screw 1a of the support rod 1 moves inwardly into the connector 2 through the female screw of the connector 2 and moves the telescopic connector 4 toward the end of the opening 2b of the connector 2. Since the elastic connector 4 which is opened by forcible movement is brought close to each other, the reinforcing bars, the elastic connector, the connecting pipe 2, and the support bar 1 are integrally fixed in the polygonal inclined guide surface 4c.
When the reinforcing bar is connected to the other connecting pipe 3, the rebar connecting pipe 3 is inserted into the other open part 3b and the elastic connector 4 is separated to couple the reinforcing bar to the reinforcing receiving grooves 4a and 4b. Next, when the reinforcing bar is rotated, the connecting pipe 3 integrated with the reinforcing bar is rotated to be coupled to the male screw 1a of the supporting rod 1 so that the flexible connector 4 is connected to the end of the opening 3b of the connecting pipe 3. Since the movement is close to each other and fixed in the polygonal slope and the reinforcing bars are fixed, the reinforcing bar is fixed by the connecting pipe (3) and the connection is made tight and fluctuation-free reinforcement, and the connection work is quick.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
