Description
본 고안은 철근 연결구에 관한 것으로 종래 토목 건축물의 구축시에 철근을 연결할 경우 대부분 철근 겹이음(Lapping) 공법을 사용하였다.The present invention relates to a reinforcing bar connector. In the case of connecting a reinforcing bar in the construction of a conventional civil building, a reinforcing bar lapping method was used.
그러나 철근 이음부의 항복강도, 인장강도가 높지 못하여 부실 시공을 초래하게 되고 그로 인하여 구축물의 안정성과 수명에 문제점이 있었다.However, the yield strength and the tensile strength of the reinforcing bar parts are not high, resulting in poor construction, thereby causing problems in stability and lifespan of the structure.
종래 이러한 문제점을 시정하기 위하여, 연결할 철근의 단부를 롤링하여 나사를 삭성(削成)하고 나사공이 양단부에 형성된 카플러에 철근의 단부에 삭성된 나사를 나삽(螺揷)하여 연결하는 것이 알려저 있다.Conventionally, in order to correct this problem, it is known to roll the end of the reinforcing bar to cut the screw and to connect the screw cut to the end of the bar by screwing the coupler formed at both ends. .
종래의 나사 연결공법은 철근의 겹이음 공법에 비하여 철근의 항복강도와 인장강도가 보다 높은 이점은 있으나 각 철근의 단부마다 일일히 나사를 삭성하기 위하여 롤링하는 작업이 번거롭고 인력이 많이 들뿐 아니라 시간이 오래 걸리기 때문에 공기(工期)가 연장되는 문제점이 있었다.Conventional screw connection method has higher yield strength and tensile strength than rebar splicing method, but it is cumbersome, labor-intensive and time-consuming to roll screws for each rebar end. Since this takes a long time, there was a problem in that the air was extended.
본 고안은 종래의 이러한 문제점을 시정하고 보다 간편 신속하게 철근을 연결하기 위하여, 철근을 협지하는 좌우로 분할 형성된 방추상(放錘狀)의 협지구(挾持具)와, 철근을 협지(挾持)한 상기 협지구(挾持具)를 견고하게 체결하는 체결구(締結具)의 결합으로 된 철근의 연결구(Coupler)를 개발하였다.The present invention corrects these problems in the prior art, and in order to connect the reinforcing bars more easily and quickly, the narrowing region of the fusiform formed in the left and right to sandwich the reinforcing bars, and the reinforcing bars Coupler has been developed as a combination of fasteners that firmly fasten the narrow strip.
상기 협지구는 철근을 협지하는 협지홈이 형성된 2개의 협지편이 철근의 횡방향의 양측에서 서로 결합하여 철근을 협지하게 되어 있고 협지구의 외주면은 중간부에서 양단부측으로 테이퍼진 방추상으로 형성되어 있다.In the gripping zone, two gripping pieces formed with gripping grooves for gripping the reinforcing bars are coupled to each other on both sides in the transverse direction of the reinforcing bars to hold the reinforcing bars.
상기 협지구를 고정 체결하는 체결구는 상기 협지구의 테이퍼진 외주면과 상응하게 테이퍼진 체결공이 형성된 2개의 체결관으로 되어 있고 체결관을 철근의 길이 방향에서 대향하여 협지구의 양단부측에서 체결공에 끼워 체결관의 결합단부에 형성된 나사부에 의하여 서로 결합할 때의 테이퍼 진 체결공과 체결구의 압착작용으로 철근을 협지한 협지구의 협지편을 강력하게 체결하게 되어 있으며 각 체결관의 외다부에는 육각의 헤드가 형성되어 공구를 이용하여 강력하게 틀 수 있으며 상기 나사부에는 접착제를 주입하여 나사부를 고착시키는 통공이 형성되어 있다.The fasteners for fastening the narrow strip are composed of two fastening pipes with tapered fastening holes corresponding to the tapered outer circumferential surface of the narrow strip, and are fastened to the fastening holes on both ends of the narrow strip by facing the fastening pipe in the longitudinal direction of the rebar. The threaded portion formed at the joint end of the pipe strongly tightens the clamping piece of the clamping zone which clamped the rebar by the tapered fastening hole and the fastening action of the fastener, and a hexagonal head is formed at the outer end of each fastening pipe. The tool can be strongly turned using a tool, and a hole is formed in the screw portion to fix the screw portion by injecting an adhesive.
본 고안은 철근 콘크리트 구축물의 철근을 연결하고자 할 때 연결할 철근의횡방향의 양측방에서 협지구의 각 협지편에 형성된 협지홈에 연결할 철근의 일직선으로 연결되게 협지시키고 철근의 길이방향에서 대향하여 상기 협지구의 양단부를 체결관의 체결공에 각각 끼워 양 체결관의 결합단부에 형성된 나사부를 서로 나삽하고 체결관의 외단부에 형성된 육각헤드를 공구로 틀어서 견고하게 나합(螺合)한다. 이렇게 체결관끼리의 결합시의 테이퍼진 체결공과 협지편의 테이퍼진 외주면과의 압착력에 의하여 서로 대향된 2개의 협지편은 더욱 견고하게 압착되면서 연결할 철근을 협지한다. 강력하게 조인 체결구의 나사부에 형성된 통공에 접착제를 주입하여 나사부가 풀리지 않게 고착함으로서 철근의 연결공정이 종료된다.The present invention is to sandwich the reinforcing bars of the reinforcement concrete structure to be connected in a straight line of the reinforcing bars to be connected to the sandwich grooves formed in each of the sandwich pins in the lateral direction of the reinforcing bars in the cross direction of the reinforcing bars to be connected, Both ends of the earth are inserted into the fastening holes of the fastening pipe, respectively, and the screw parts formed at the joint ends of the fastening pipe are screwed together, and the hexagonal heads formed at the outer ends of the fastening pipe are twisted with a tool to be firmly screwed together. Thus, the two clamping pieces which face each other by the pressing force of the tapered fastening hole and the tapered outer peripheral surface of the clamping piece at the time of joining of the fastening tubes clamp more firmly, and clamp the reinforcing bars to be connected. The connection process of the reinforcing bar is completed by injecting an adhesive into the through hole formed in the threaded portion of the fastening fastener securely so that the threaded portion does not loosen.
본 고안의 연결구에 의하여 연결된 철근의 연결부는 철근 모재보다 강력하여 항복 및 인장강도 높고 반복하중이나 진동에도 내구성이 양호하여 종래의 겹이음 공법에 비하여 철근의 구축강도가 향상되며 또한 연결작업이 간편하여 보다 능률적으로 다량의 철근의 연결작업이 가능하게 안출한 것이다.The connecting part of the reinforcing bar connected by the connector of the present invention is stronger than the reinforcing bar base material, which has higher yield and tensile strength, and good durability against repeated loads or vibrations, so that the construction strength of the reinforcing bar is improved compared to the conventional lap method and the connection work is simple. It is possible to connect a large amount of rebars more efficiently.

After tightly tightening the fastening tube, the adhesive is injected into the through hole (2h) formed in the screw portion (2n) of the fastener (2) to fix the screw portion to connect the two reinforcement in a straight line.
이렇게 연결된 철근은 항복과 인장강도가 높으며 어떠한 반복 하중에나 진동에도 절단되거나 분리되는 일이 없이 모재 철근이상의 강도를 유지하게 된다.The connected reinforcing bar has high yield and tensile strength and maintains the strength of the base reinforcing bar without being cut or separated by vibration under any repeated load.
본 고안은 방추상으로 된 2개의 협지편으로 된 협지구에 의하여 연결할 철근을 협지하고 2개의 체결관으로 된 체결구의 나사결합에 의하여 협지구의 협지편을 강력하게 체결할 수 있게 구성하였기 때문에 연결구의 구조가 간단하고 운반 취급이 용이하며 사용이 간편하다.The present invention is designed to secure the reinforcing bars to be connected by the narrow strip of two narrow pieces of fusiform and to fasten the narrow pieces of the narrow strip by screwing the fasteners of the two fastening pipes. Simple structure, easy handling and easy to use.
체결관에 형성된 육각 헤드를 이용하여 체결관의 나사부를 틀 수 있게 되어 있기 때문에 작업성이 양호하고 견고하게 철근을 연결할 수 있어, 연결된 철근의 연결부는 모재 철근이상으로 항복, 인장강도가 높게 되고 반복하중이나 진동에도 절단 분리되는 일이 없어 철근 콘크리트 구축물의 안전성이 매우 높게 된다.The hexagonal head formed in the fastening pipe enables the screw thread of the fastening pipe to be twisted, so that the workability is good and the steel can be firmly connected.The connection of the connected steel reinforcement yields higher tensile strength and repetition than the base steel. It is not cut and separated even under load or vibration, so the safety of reinforced concrete construction is very high.
또 철근 연결의 작업성이 양호하여 종래의 것에 비하여 보다 간편 신속하게 능률적으로 철근 콘크리트 구축물의 철근을 연결할 수 있는 등의 여러가지 효과가 있다.In addition, since the workability of the reinforcing bar is good, there are various effects, such as being able to connect the reinforcing bar of reinforced concrete construction more easily and quickly and efficiently than the conventional one.
