Abstract

본 발명은 철근 커플러가 서로 연결하는 두개의 슬리브가 나사산이 형성된 나사결합 방식으로 상호 간편하게 연결할 수 있도록 직접 결합된다. 두 슬리브의 연결을 위한 다른 추가적인 구성이 구비될 필요가 없고, 슬리브 내에 탄성복원 가능하도록 구비되는 하나의 탄성체가 턴버클이 형성된 코일스프링 양단에 슬리브의 걸림홈부에 각각 끼워져 결합된다. 조립시 탄성부재를 고정하기 위한 별도의 부품을 사용하지 않고 직접 스프링을 안착시켜 철근이 내부에 인입시 두개의 철근이 동일한 선상에서 안정적으로 인입이 보장된다. 인입된 철근이 이탈 방지 하는 내부커버를 포함하되, 하나의 몸체 형상을 갖도록 하여 철근이 서로 연결될수 있도록하는 것이 특징이다. 이로 인해 전체적으로 내구성이 향상되며 부품수의 감소로 인한 무게와 부피를 현저히 줄일수 있을뿐 아니라 커플러의 설계구조또한 크게 단순화 되므로 쉽고 간편하게 연결할 수 있는 콘넥트 철근커플러. In the present invention, the two sleeves to which the reinforced couplers are connected to each other are directly coupled so that they can be easily connected to each other by a threaded screw connection method . There is no need to provide another additional configuration for connecting the two sleeves, and one elastic body provided to enable elastic restoration in the sleeve is fitted and coupled to each of the locking grooves of the sleeve at both ends of the coil spring on which the turnbuckle is formed. When assembling, the spring is directly seated without using a separate part to fix the elastic member, so that when the reinforcing bar is inserted into the inside, the two reinforcing bars are secured on the same line. It includes an inner cover that prevents the reinforcement from being pulled in, but has a single body shape so that the reinforcing bars can be connected to each other . This improves the overall durability and significantly reduces the weight and volume due to the reduction in the number of parts, as well as greatly simplifies the design structure of the coupler, making it easy and convenient to connect .

Description

콘넥트 철근 커플러 {Coupler For Rebar Connect}Connect Rebar Coupler {Coupler For Rebar Connect}

본 발명은 철근을 서로 연결하기위한 것으로. 철근을 강한 힘으로 고정할수 있도록 함께 연결할 수 있는 콘넥트 철근 커플러에 관한 것이다. The present invention is intended to connect reinforcing bars to each other. It relates to a connect reinforcing bar coupler that can be connected together to fix the reinforcing bars with strong force.

건설현장에서 콘크리트 구조물에 사용하기 위한 철근을 연결하기 위 해서 철근을 이중으로 겹친 상태에서 철사 등으로 묶어서 고정하였으 나, 작업이 번거롭고 철근의 중심이 수직이 되지 않고 삐뚫어질 뿐 아니라 철사의 강도가 약하기 때문에 쉽게 끊어지면서 연결상태가 해제되는 문제점이 있었다. In order to connect the reinforcing bars for use in concrete structures at the construction site, the reinforcing bars were doubled and fixed with wires, etc., but the work is cumbersome and the center of the rebars is not vertical, and the strength of the wires is not Since it is weak, there is a problem in that it is easily disconnected and the connection state is released.

종래에 개발된 철근 커플러들의 대부분은 구조적으로 생산이 복잡하 며 철근의 연결작업이 어려워 작업에 많은 시간과 비용이 소요되는 문제가 있다. Most of the conventionally developed rebar couplers are structurally complicated to produce, and it is difficult to connect the rebars, so that a lot of time and cost are required.

이러한 문제를 해결하기 위한 것으로, 전체적인 무게와 부피를 현 저히 줄일수 있을뿐 아니라 커플러의 설계구조가 종래에 비해 크게 단순화 되므로 쉽고 간편하게 연결할수있는 철근 커플러가 안출 되고 있다.In order to solve this problem, not only can the overall weight and volume be significantly reduced, but the design structure of the coupler is greatly simplified compared to the prior art, so that a rebar coupler that can be easily and conveniently connected has been devised.

이러한 선행기술에는 대한민국 등록특허공보 제 101643846호 등록특허공보 제 101683143호와 같은 기술들이 개시되어 있다.In such prior art, technologies such as Korean Patent Publication No. 101643846 No. 101683143 are disclosed.

대한민국 등록특허공보 제10-1643846호(2016.08.10.)Republic of Korea Patent Publication No. 10-1643846 (2016.08.10.) 대한민국 등록특허공보 제10-1683143호(2016.12.06.)Republic of Korea Patent Publication No. 10-1683143 (2016.12.06.)

본 발명은 철근과 철근을 연결하되 철근과 커플러와의 결속력을 강 화시켜 철근이 커플러로 부터 분리되는 것을 방지한다. 간단하게 철근을 커플러에 연결하도록 하여 작업효율성을 크게 향상시키고 작업시간을 단축할수 있으며, 타설된 콘크리트에 의한 지지성을 가질수 있도록한 개량 철근 커플러를 제공함에 그 목적이 있다.The present invention connects the reinforcing bar and the reinforcing bar, but strengthens the binding force between the reinforcing bar and the coupler to prevent the reinforcing bar from being separated from the coupler . Its purpose is to provide an improved reinforced coupler capable of greatly improving work efficiency and shortening working time by simply connecting the reinforcing bar to the coupler, and having supportability by poured concrete.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 콘넥트 철근 커 플러는, 상단부와 하단부 각각에 철근이 삽입되는 입구가 형성되어 있고, 입구에서 반대편으로 갈수록 점진적 으로 내경이 커지는 테이 퍼부가 형성되어 있고 내측면에 철근의 마디가 걸리면서 지지되는 복수개의 편체(20)들이 오므려지면서 편체의 록킹돌기(22)들이 철근의 외면에 압착되는 것을 특징으로 한다. In the connect reinforcing bar coupler according to the present invention for achieving the above object, an inlet into which a reinforcing bar is inserted is formed in each of the upper and lower portions, and a tapered portion is formed that gradually increases the inner diameter from the inlet to the opposite side. It is characterized in that the locking protrusions 22 of the knitting body are compressed to the outer surface of the reinforcing bar while the plurality of pieces of the piece 20 supported while the nodes of the reinforcing bar are caught on the inner surface are closed.

각각의 편체(20) 밑단부에 수용홈(21)이 형성되어 탄성체 코일스프링(30)을 편체 결합홈(21)에 안착시켜 커플러 내부에서 탈선을 방지하고 복수의 편체들이 간격을 유지할 수 있다. 이후에 철근이 삽입되면서 탄성력으로 오므려질 때 각각의 편체들(20)이 거의 동시에 철근을 균일한 힘으로 고정할 수 있게 된다.The receiving groove 21 is formed at the bottom end of each of the knitted bodies 20 so that the elastic coil spring 30 is seated in the knitted body coupling groove 21 to prevent derailment inside the coupler, and the plurality of knitted bodies can maintain a gap . Subsequently, when the reinforcing bar is inserted and closed by an elastic force, each of the pieces 20 can fix the reinforcing bar with a uniform force almost at the same time.

상기 내부커버편체(20)를 고정하기 위한 별도의 부품을 사용하지않고 직접 탄성체 코일스프링(30)을 안착시켜 부품수의 감소로 인한 제작원가의 절감과 함께 조립공정이 줄어들어 생산성이 향상된다. By directly mounting the elastic coil spring 30 without using a separate part for fixing the inner cover piece 20, the manufacturing cost is reduced due to the reduction in the number of parts and the assembly process is reduced, thereby improving productivity.
