Description

철근 이음구{A reinforced rod connector}Reinforcing bar connector {A reinforced rod connector}

본 발명은 철근 이음구에 관한 것으로, 특히 철근과 철근 끝단부를 연결하는 철근 이음구의 부품수를 줄여 생산원가는 절감하고 조립은 간편하게 이루어지게 함은 물론 이음관의 형상에 따라 철근의 직선 이음 및 곡선 이음에 모두 적용될 수 있도록 한 철근 이음구에 관한 것이다.The present invention relates to a reinforcing bar, in particular, to reduce the number of parts of the reinforcing bar connecting the reinforcing bar and the reinforcing bar production costs and to simplify the assembly, as well as straight joints and curved joints of the rebar according to the shape of the pipe It is about a reinforcing bar that can be applied to both.

일반적으로 사용하는 철근 이음구는 대형 구조물의 기둥이나 벽체등의 수직방향으로 세워진 철근을 수직방향으로 연장시키기 위하여 다른 철근과 이어주거나 또는 원형교각에 수직으로 세워진 다수의 철근을 원형으로 감는 띠철근을 하나로 연결시키기 위한 목적으로 사용된다.Commonly used reinforcing bar is connected with other reinforcing bars in order to extend vertically reinforcing bars such as pillars or walls of large structures in a vertical direction. Used for the purpose of connection.

상기한 목적으로 사용되는 철근 이음구중 띠철근의 끝단부를 이어주는 방법은 원형 교각내에 일정한 간격을 두고 다수의 철근이 세워지면 띠철근으로 상기 철근을 원형으로 감고 끝단부를 철근 이음구로 이어준다. 이때 철근 이음구는 띠철근의 끝단부를 원형으로 연결시키기 위해 약간 휘어진 호형상의 원통형으로 구성되어 있다.The method of connecting the end of the band reinforcing bar of the reinforcing bar joint used for the above purpose is to wound the reinforcing circle with the band reinforcing bars and the end is connected to the reinforcing bars when a plurality of reinforcing bars are erected at regular intervals in the circular piers. At this time, the reinforcing bar is composed of a cylindrical shape slightly curved to connect the end of the strip reinforcing in a circle.

상기 철근 이음구를 이용하여 띠철근을 이어주고자 할때에는 원통형의 이음구 내로 띠철근의 끝단부를 각각 삽입한 다음 이를 용접하거나 이음구 외주면을 압착공구로 압착시켜 이음구 내의 철근 끝단부를 고정 시키기게 되나, 용접하는 경우에는 철근의 용접부위가 가열되어 철근 취성의 증가나 연성의 저하로 인하여 다른 철근의 부위에 비해 강도가 저하되는 단점이 있었고, 압착하는 경우에는 그 압착 작업이 매우 어려울뿐 아니라, 압착한다 하더라도 압착력이 크게 작용하는 부위에 큰 잔류 응력이 존재하기 때문에 적은 국부적인 충격에 의해서도 그 이음부위에 균열이 발생하거나 이음상태가 해체되어 버리는 제반 단점이 있었다.When connecting the reinforcing bars using the reinforcing bars, each end of the reinforcing bars is inserted into the cylindrical fitting hole, and then welded or crimped to the outer peripheral surface of the joint using a crimping tool to fix the reinforcing bar ends in the fitting. In this case, the welding part of the reinforcing bar is heated and the strength of the reinforcing bar is reduced due to the increase in brittleness or ductility.Therefore, the crimping work is very difficult in the case of pressing, and the pressing force is reduced even when pressing. Since there is a large residual stress in this largely acting site, there are disadvantages in that cracks are generated or the joints are dismantled even by a small local impact.

따라서 종래에는 상기의 단점을 해결하기 위하여 여러 가지의 철근 이음구가 안출된바 있으나. 종래 철근 이음구는 조립 하는데 필요한 핵심 부품이 적게는 5개소에서 많게는 9개소로 구성되어 있어 현장에서 조립 하는데 불편하였으며 많은 부품 제작으로 인해 제조원가가 상승하는 단점이 있었다.Therefore, in the related art, in order to solve the above disadvantages, various rebar joints have been devised. Conventional reinforcing bar is composed of as few as 5 core parts necessary to assemble, so it is inconvenient to assemble in the field, and manufacturing cost increases due to the production of many parts.

한편, 철근 이음구를 이용하여 직선형 철근을 이음하고자 할때에는 중공의 원통형 커플러내에 암나사부를 형성하고, 반원통형의 중간부재 외주면에는 숫나사부를 내주면에는 골을 각각 형성한 후, 상기 중간부재의 숫나사가 커플러의 암나사에 합치되도록 중간부재를 회전 시킴으로서 커플러에 나사 결합시키는 방법이기 때문에 원형 띠철근을 따라 호형태로의 조립이 불가능한 단점이 있을뿐 아니라 철근의 직선이음 방식이나 곡선이음 방식에 따라 각기 다른 별도의 구조를 갖는 철근 이음구를 구비해야 하는 제반 문제점이 있었다.On the other hand, when using a reinforcing bar to connect a straight reinforcing bar to form a female thread in the hollow cylindrical coupler, the outer peripheral surface of the semi-cylindrical male member formed a bone on the inner peripheral surface, respectively, the male screw of the intermediate member The method of screwing the coupler to the coupler by rotating the intermediate member to match the female thread has the disadvantage that it is impossible to assemble the arc along the circular band reinforcement, and also has a separate structure depending on the straight or curved joint method of the rebar. There were various problems to be provided with a reinforcing bar having a.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로, 철근과 철근 끝단부를 연결하는 철근 이음구의 부품수를 줄여 생산원가는 절감하고 조립은 간편하게 이루어지게 함은 물론 이음관의 형상에 따라 철근의 직선 이음 및 곡선 이음에 모두 적용될 수 있도록 한 철근 이음구를 제공하는데 있다.Therefore, the object of the present invention is to devise in view of the above-mentioned conventional problems, to reduce the number of parts of the reinforcing bar connecting the reinforcing bar and the reinforcing bar to reduce the production cost and simplify the assembly, as well as the shape of the pipe According to the present invention to provide a reinforcing bar joint so that it can be applied to both straight joints and curved joints of the rebar.
