이하, 본 발명을 첨부된 도면에 의하여 더욱 상세히 설명하면 다음과 같다.
첨부된 도면들 중에서 동일한 구성 요소들은 가능한 어느 도면에서든지 동일한 부호를 사용하고 있음을 유의해야 하며, 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 또는 공지 구성에 대한 상세한 설명은 생략하였음을 미리 밝혀두는 바이다.

이와 같이 된 본 발명은 철근 연결구의 지지봉(1)양단에 연결관(2, 3)의 암나사부(2a, 3a)가 나사 조립된다.
또한, 연결관(2, 3)의 개방부(2b, 3b)가 내측이 넓고 외측으로 축소되는 경사면을 가지고 다각형 면으로 되어 그 속에 반분체로 되고 내면에 철근수용홈(4a, 4b)이 형성되고 외면이 내측의 직경이 크고 외측의 직경이 적은 경사면으로 된 다각형 안내면(4c)이 구비된 신축형 접속자(4)가 개입된다.
따라서 내부에 설치된 코일스프링(5)에 의하여 연결관(2, 3)의 개방부(2b, 3b) 쪽으로 밀리면서 탄력을 받아 슬라이드 되므로 철근을 연결할 때 일측 연결관(2)의 개방부(2b)로 철근 끝을 투입하면 연결관(2)의 개방부(2b) 끝에 이동되어 있던 신축형 접속자(4)가 철근에 밀려서 내향하므로 신축형접속자 사이가 이완되어 벌어지고 그 사이로 철근이 삽입되어 끝이 지지봉(1) 양측에 형성된 돌출봉(1b)에 닿으면 철근의 세로방향돌조(6a)는 신축형 접속자(4)의 세로방향 철근수용홈(4a)에 결합하고 철근의 가로방향돌조실(6b)은 신축형 접속자(4)의 가로방향 철근수용홈(4b)에 투입되는 결합이 이루어지게 된다.
이러한 상태에서 코일스프링(5)의 탄력에 의하여 연결관(2) 개방부(2b) 쪽으로 탄력을 받아 이동하게 되는데 이때 지지봉(1) 중간에 천공된 구멍(1d)으로 렌치(7)를 투입하여 회전시키면 지지봉(1)의 수나사(1a)가 연결관(2의 암나사를 타고 연결관(2)속으로 내향 이동하면서 신축형 접속자(4)를 연결관(2)의 개방부(2b) 끝쪽으로 강제 이동시켜서 벌어진 신축형 접속자(4)를 근접시키므로 철근과 신축형접속자와 연결관(2)과 지지봉(1)이 다각형 경사 안내면(4c) 내에서 일체로 고정되게 된다.
그리고 타측연결관(3)에 철근을 연결할 때는 철근연결관(3)의 타측 개방부(3b)로 투입하여 신축형 접속자(4)를 이간시켜서 철근수용홈(4a, 4b)에 철근을 결합시킨 다음 철근을 회전시키면 철근과 일체로 된 연결관(3)이 회전하여 지지봉(1)의 수나사(1a)에 결합하므로 신축형 접속자(4)가 연결관(3)의 개방부(3b) 끝으로 이동하여 상호 근접하므로 다각형 경사면 내에서 고정되고 철근을 고정하게 되므로 연결관(3)에 의하여 철근이 고정되고 긴밀하고 요동 없는 철근연결이 이루어지고 연결작업이 신속하게 되는 효과가 있다.

이상에서는 본 발명의 바람직한 실시 예에 대하여 도시하고 설명하였으나, 본 발명은 상술한 특정의 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시나 응용이 가능한 것은 물론이고, 이러한 변형 실시나 응용 예는 본 발명의 기술적 사상이나 전망으로부터 개별적으로 이해돼서는 안 될 것이다.
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.
