Description

철근연결구{reinforcing rod connector}Reinforcing rod connector

본 발명은 철근연결구에 관한 것으로서, 보다 상세하게는 철근의 연결이 쉽고, 철근이 손상되는 것을 방지할 수 있도록 된 철근연결구에 관한 것이다.The present invention relates to a reinforcing bar connector, and more particularly, to a reinforcing bar connector that is easy to connect the reinforcing bars, to prevent damage to the reinforcing bar.

일반적으로, 대형건물이나 토목공사에서 콘크리트구조물의 시공하는 경우에, 철근을 연결하여 사용할 때는, 대직경 철근은 별도의 연결구를 이용하여 연결하여 철근의 강도를 유지할 수 있도록 규정되어 있다.In general, in the case of construction of concrete structures in large buildings or civil works, when connecting the reinforcing bars, large diameter reinforcing bars are provided to maintain the strength of the reinforcing bars by using a separate connector.

종래에 사용되는 이러한 연결구로는 상호 연결되는 철근의 단부에 내주면에 돌기가 형성된 철편을 각각 결합하고, 이 철편을 별도로 제작된 관체의 양단에 나사결합하거나, 관체의 양단에 철근의 단부를 각각 삽입한 후, 상기 관체에 결합된 고정나사를 조여 철근이 빠지는 것을 방지할 수 있도록 하였다.Conventionally, such a connector is used to couple the iron pieces each having a protrusion on the inner circumferential surface at the ends of the reinforcing bars, and screw the iron pieces to both ends of a separately manufactured pipe, or insert the ends of the steel bars at both ends of the pipe, respectively. Afterwards, the fixing screw coupled to the tube was tightened to prevent the rebar from falling out.

그러나, 전술한 철편을 이용한 연결구는 철편의 내측에 형성된 돌기가 철근의 둘레면에 형성된 돌기와 맞물려 철근을 고정하는 것으로, 상호 연결된 철근이 과도하게 당겨질 경우, 돌기가 파손되어 철근을 견고하게 연결하기 어려울 뿐 아니라, 철편이 철근의 단부에 정확히 결합되지 않을 경우, 철편의 둘레면에 형성된 나사가 관체의 내주면에 형성된 나사와 잘 맞지 않아서, 관체에 철편을 결합하기 어려운 문제점이 있었다. 또한, 고정나사를 이용한 연결구의 경우, 나사로 철근의 둘레면을 가압하여 철근을 고정하므로, 나사를 조이는데 많은 힘이 들뿐 아니라, 나사에 의해 가압된 철근의 둘레면에 손상이 발생되어 철근의 강도가 약해질 수 있는 문제점이 있었다.However, the connector using the above-described iron piece is a projection formed on the inside of the iron piece is fixed to the reinforcing the reinforcing the reinforcing bar, when the interconnected reinforcement is pulled excessively, it is difficult to connect the reinforcement firmly to the reinforcement In addition, when the iron piece is not exactly coupled to the end of the rebar, the screw formed on the circumferential surface of the iron piece does not fit well with the screw formed on the inner circumferential surface of the tube, there was a problem that it is difficult to join the iron piece to the tube. In addition, in the case of a connector using a fixing screw, the reinforcing bar is fixed by pressing the circumferential surface of the rebar with a screw. Therefore, not only a lot of force is required to tighten the screw, but also damage occurs on the circumferential surface of the reinforcing bar pressed by the screw. There was a problem that the strength can be weakened.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 연결작업이 손쉬울 뿐 아니라, 철근이 손상되는 것을 방지할 수 있도록 된 새로운 구조의 연결구를 제공하는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a connector having a new structure, which is not only easy to connect, but also to prevent damage to the rebar.

Reinforcing bar connectors are provided.

본 발명의 다른 특징에 따르면, 상기 키(14)의 내측면 모서리부에는 돌출부(16)가 형성되며, 상기 철근(4,6)이 당겨짐에 따라 철근(4,6)에 형성된 돌기(12)에 상기 돌출부(16)가 걸려 키(14)가 회동되면, 상기 돌출부(16)가철근(4,6)의 둘레면을 가압하여 철근(4,6)을 고정할 수 있도록 된 것을 특징으로 하는 철근연결구가 제공된다.According to another feature of the present invention, the protrusion 16 is formed on the inner edge of the key 14, the projections 12 formed on the reinforcing bars (4, 6) as the reinforcing bars (4, 6) is pulled When the protrusions 16 are caught and the key 14 is rotated, the protrusions 16 can press the circumferential surfaces of the reinforcing bars 4 and 6 to fix the reinforcing bars 4 and 6. Rebar connectors are provided.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1 및 도 2는 본 발명에 따른 철근연결구를 도시한 것으로, 관체로 구성된 내관체(2)의 양단에는 상호 연결되는 철근(4,6)의 단부가 각각 삽입결합된다.1 and 2 show the reinforcing bar connector according to the present invention, the ends of the reinforcing bars (4, 6) are connected to both ends of the inner tube (2) consisting of a tubular body, respectively.

상기 내관체(2)는 그 둘레면에 다수개의 결합공(8)이 형성되며, 그 상측에는 내관체(2)의 외경보다 지름이 약간 작은 숫나사부(10)가 형성된 것으로, 상기 결합공(8)에는 상기 철근(4,6)의 둘레면에 형성된 돌기(12)에 걸려 철근(4,6)을 고정하는 키(14)가 각각 삽입되며, 키(14)가 결합된 내관체(2)의 외부에는 상기 키(14)가 빠지는 것을 방지하는 외관체(18)가 결합된다.The inner tube body 2 is formed with a plurality of coupling holes (8) on the circumferential surface, the upper side is formed with a male thread portion 10 is slightly smaller than the outer diameter of the inner tube body 2, the coupling hole ( 8, a key 14 is inserted into each of the projections 12 formed on the circumferential surfaces of the reinforcing bars 4 and 6, and the keys 14 for fixing the reinforcing bars 4 and 6 are respectively inserted, and the inner tube 2 to which the keys 14 are coupled. Outside the) is coupled to the outer body 18 to prevent the key 14 from falling out.

상기 키(14)는 그 내측면이 라운드형태로 제작되어 상기 철근(4,6)의 둘레면에 밀착되도록 구성된 것으로, 그 내측면에는 돌출부(16)가 형성된다. 이 돌출부(16)는 대략 사각형의 단면형상으로 제작된 키(14)의 내측면 상,하측 모서리부에 반경이 다른 라운드를 각각 형성하여, 일측 모서리부가 타측 모서리에 비해 돌출되도록 구성된 것으로, 상기 철근(4,6)이 당겨질 경우, 상기 돌출부(16)가 철근(4,6)에 형성된 돌기(12)에 걸려 키(14)가 회동되도록 한다.The key 14 is formed so that its inner surface is rounded and closely adhered to the circumferential surfaces of the reinforcing bars 4 and 6, and the protrusions 16 are formed on the inner surface thereof. The protruding portion 16 is formed by forming rounds having different radii on upper and lower corners of the inner side of the key 14 manufactured in the shape of a substantially rectangular cross-section, so that one corner portion protrudes from the other corner. When (4, 6) is pulled out, the projection (16) is caught by the projection (12) formed in the reinforcing bars (4, 6) to allow the key (14) to rotate.

따라서, 도 2에 도시한 바와 같이, 상기 돌출부(16)가 내관체(2)의 길이방향 중앙부쪽, 즉, 고정되는 철근(4,6)이 당겨지는 방향의 반대쪽을 향하도록 키(14)를상기 결합홈에 삽입결합하면, 상기 철근(4,6)이 당겨질 경우, 상기 돌출부(16)가 철근(4,6)에 형성된 돌기(12)에 걸려 키(14)가 회동되며, 이에따라, 상기 돌출부(16)가 철근(4,6)의 둘레면을 가압하여 철근(4,6)이 움직이지 않도록 고정하게 된다. 이때, 상기 돌출부(16)에 비해 지름이 큰 라운드로 형성된 내측 모서리부는 키(14)가 용이하게 회동될 수 있도록 하는 역할을 한다.Thus, as shown in Fig. 2, the protrusions 14 are directed toward the longitudinal center portion of the inner tube body 2, i.e., opposite to the direction in which the fixed reinforcing bars 4 and 6 are pulled. When the coupling is inserted into the coupling groove, when the reinforcing bars 4 and 6 are pulled, the protrusions 16 are caught by the projections 12 formed on the reinforcing bars 4 and 6, so that the key 14 is rotated. The protrusion 16 presses the circumferential surfaces of the reinforcing bars 4 and 6 to fix the reinforcing bars 4 and 6 so as not to move. At this time, the inner edge portion formed in a round having a larger diameter than the protrusion 16 serves to allow the key 14 to be easily rotated.

상기 돌출부(16)는 전술한 바와 같이, 키(14)의 내측면 모서리부에 라운드를 형성하는 것 이외에, 대략 사각단면형상으로 구성된 키(14)의 일측 모서리부에 별도의 돌기나 돌출단을 형성하여, 키(14)의 회동시 이 돌기 또는 돌출단이 철근(4,6)의 둘레면을 가압하도록 구성하는 것도 가능하다.As described above, the protrusion 16 may form a separate protrusion or protrusion at a corner of one side of the key 14 having a substantially rectangular cross-sectional shape, in addition to forming a round at an inner edge of the key 14. It is also possible to form such a protrusion or protrusion that presses the circumferential surfaces of the reinforcing bars 4 and 6 when the key 14 is rotated.

그리고, 상기 외관체(18)는 그 내주면 상측에 상기 내관체(2)의 상단에 걸리는 걸림턱(20)이 형성된 것으로, 이 외관체(18)를 상기 내관체(2)의 외부에 결합한 후, 내관체(2)의 상측으로 연장형성된 나사부(10)에 너트(20)를 결합하여 외관체(18)를 고정할 수 있다. 본 실시예의 경우, 상기 외관체(18)와 너트(20)를 각각 별도로 구성하였으나, 제작자의 의도에 따라, 상기 외관체(18)와 너트(20)를 일체로 제작하는 것도 가능하다.In addition, the outer body 18 is formed on the inner circumferential surface above the engaging jaw 20 to be caught on the upper end of the inner tube body 2, after combining the outer body 18 to the outside of the inner tube body 2 The outer shell 18 may be fixed by coupling the nut 20 to the screw portion 10 extending upwardly of the inner tube body 2. In the present exemplary embodiment, the exterior body 18 and the nut 20 are separately configured, but according to the intention of the manufacturer, the exterior body 18 and the nut 20 may be integrally manufactured.

이와같이 구성된 철근연결구는 상기 내관체(2)의 양단에 철근(4,6)의 단부를 각각 삽입하고, 내관체(2)의 결합공(8)에 키(14)를 삽입결합한 후 내관체(2)의 외측에 외관체(18)를 결합하면, 상기 키(14)의 내측면이 철근(4,6)에 형성된 돌기(12)에 걸려 철근(4,6)이 빠지는 것을 방지할 수 있으므로, 연결작업이 간단한 장점이 있다.The reinforcing connector configured as described above inserts end portions of the reinforcing bars 4 and 6 at both ends of the inner tube body 2, and inserts the key 14 into the coupling hole 8 of the inner tube body 2, and then the inner tube body ( When the exterior body 18 is coupled to the outside of 2), the inner surface of the key 14 can be caught by the projection 12 formed on the reinforcing bars 4 and 6, thereby preventing the reinforcing bars 4 and 6 from falling out. This has the advantage of simple connection.

또한, 상기 철근(4,6)이 당겨질 경우, 키(14)가 회동되어 철근(4,6)의 둘레면을 가압하여 고정하므로, 철근(4,6)의 돌기(12)나 철근(4,6)의 둘레면이 손상되는 것을 방지할 수 있으며, 철근(4,6)을 견고하게 연결할 수 있는 장점이 있다.In addition, when the reinforcing bars 4 and 6 are pulled, the key 14 is rotated to press and fix the circumferential surfaces of the reinforcing bars 4 and 6, so that the protrusions 12 and the reinforcing bars 4 of the reinforcing bars 4 and 6 are fixed. 6 can be prevented from damaging the circumferential surface, there is an advantage that can be firmly connected to the reinforcing bars (4,6).

이상에서와 같이 본 발명에 의하면, 양단에 상호 연결되는 철근(4,6)의 단부가 삽입결합되는 내관체(2)의 둘레면에 키(14)가 삽입되는 결합홈을 형성하고, 이 내관체(2)의 외부에 외관체(18)를 결합하므로써, 연결작업이 손쉬울 뿐 아니라, 철근(4,6)이 손상되는 것을 방지할 수 있도록 된 새로운 구조의 철근연결구를 제공할 수 있다.As described above, according to the present invention, the coupling groove into which the key 14 is inserted is formed in the circumferential surface of the inner tube body 2 into which the ends of the reinforcing bars 4 and 6 connected to both ends are inserted. By coupling the exterior body 18 to the outside of the tubular body 2, not only the connection work is easy, but also the reinforcing bar connector of a new structure which can prevent the reinforcing bars 4 and 6 from being damaged.
