Description

철근 이음구 {Connector for reinforceing rod}Reinforcing Bars {Connector for reinforceing rod}

본 발명은 철근이음구에 관한 것으로서, 보다 상세하게는 대형구조물의 지주내에 수직방향으로 세워진 철근을 수직방향으로 연장시키기 위하여 다른 철근과 이어주거나 상기 수직방향의 철근들을 횡방향으로 상호 연결시켜주는 띠철근의 끝단부를 서로 이어주는 데 사용되는 철근이음구에 관한 것이다.The present invention relates to a reinforcing bar, and more particularly, in order to extend the reinforcing bar vertically in a strut of a large structure in a vertical direction, the band reinforcing bars connected with other reinforcing bars or connecting the reinforcing bars in the transverse direction. It relates to reinforcing bar used to connect the ends of each other.

일반적인 철근이음구를 사용하여 띠철근의 끝단부를 이어주는 방법은 도 1, 2에 도시된 바와 같이, 지주(2)(2') 내에 수직방향으로 삽입된 다수의 철근(3)(3')을 횡적으로 이어주기 위하여 띠철근(1)(1')으로 상기 철근(3)(3')을 사각형상 또는 호형상으로 감아 띠철근(1)(1')의 끝단부를 철근이음구(4)(4')로서 이어준다. 도 1의 철근이음구(4)는 띠철근(1)의 끝단부를 직선상으로 이어주기 위하여 직선상의 원통형으로 형성되어 있으며 도 2의 철근이음구(4')는 띠철근(1')를 호형상으로 연결시키기 위하여 약간 휘어진 호형상의 원통형으로 형성되어 있다.A method of connecting the ends of the band reinforcing bars using a general reinforcing bar is shown in FIGS. 1 and 2, and transverses the plurality of reinforcing bars 3, 3 ′ vertically inserted into the posts 2, 2 ′. The reinforcing bar (4) (4) is wound around the reinforcing bar (3) (3 ') in the shape of a square or arc with a band reinforcing bar (1) (1'). '). The reinforcing bar 4 of FIG. 1 is formed in a straight cylindrical shape in order to connect the end of the band reinforcing bar 1 to a straight line, and the reinforcing bar 4 'of FIG. 2 makes the bar reinforcing bar 1' into an arc shape. It is formed in a cylindrical shape slightly curved to connect.

상기 철근이음구를 사용하여 철근을 이어주고자 하는 경우에는 원통형의 이음구 내로 철근의 끝단부를 각각 삽입한 다음, 이를 용접하거나 이음구 외주면을 압착공구로 압착시켜 이음구 내에 철근의 끝단부를 고정시키게 되나, 용접하는 경우에는 철근의 용접부위에 열화현상이 발생하여 다른 철근의 부위에 비해 인장강도 및 항복강도가 저하되는 문제점이 발생되고, 이음구를 압착하는 경우에는 그 압착작업이 어려울 뿐만 아니라 압착력이 크게 작용하는 부위에 큰 피로응력이 존재하게 되어 적은 국부적인 충격에 의하여도 그 이음부위에 균열이 발생하거나 이음상태가 해체되어 버리는 문제점이 있었다.When the reinforcing bars are used to connect the reinforcing bars, each end of the reinforcing bars is inserted into a cylindrical joint, and then welded or the outer peripheral surface of the joint is crimped with a crimping tool to fix the end of the reinforcing bars in the joint. In this case, the deterioration phenomenon occurs in the welded part of the reinforcing bar, which causes a problem in that the tensile strength and the yield strength are lowered compared to other reinforcing bar parts. There is a problem that a large fatigue stress is present, so that the joint is cracked or the joint is dismantled even by a small local impact.

상기한 종래기술의 문제점을 해결하기 위하여 도 3, 4에 도시된 철근이음구가 사용되고 있다.In order to solve the problems of the prior art, the reinforcing bar shown in FIGS. 3 and 4 is used.

상기의 철근이음구는 중공의 원통형커플러(5)내에 암나사부(5a)를 형성하고, 단면이 반호형상을 갖는 반원통형의 중간부재(7)의 외주면에 숫나사부(7a)와 내주면에 골(7b)을 형성하여, 상기 중간부재(7)의 숫나사가 상기 커플러(5)의 암나사에 합치되도록 중간부재를 회전시켜 커플러(5)에 나사 결합시킨 다음, 상기 커플러(5) 내로 철근(6)의 끝단부를 삽입하면 철근(6)에 형성된 보강마디(6b)가 상기 중간부재(7)의 골(7b)에 끼워지는데, 그 상태에서 커플러(5)의 일측에 나사결합된 토크볼트(8)를 회전시키면 토크볼트(8)의 끝단이 커플러(5)의 내측으로 진입되어 철근(6)을 중간부재(7)의 하측부로 압착시키면서 철근(6)의 표면에 파고들고, 토크볼트(8)를 소정의 힘 이상을 가하여 계속회전시키면 토크볼트(8)의 두부가 끊어지면서 철근(6)의 끝단부가 커플러(5) 내에 견실하게 고정된다.The reinforcing bar is formed with a female threaded portion 5a in the hollow cylindrical coupler 5, and on the outer circumferential surface of the semi-cylindrical intermediate member 7 having a semicircular cross section, the male threaded portion 7a and the bone 7b are formed on the inner peripheral surface. ), The intermediate member is rotated so that the male thread of the intermediate member (7) is matched to the female thread of the coupler (5) and screwed to the coupler (5), and then the rebar (6) of the rebar (6) When the end portion is inserted, the reinforcing node 6b formed on the reinforcing bar 6 is fitted to the valley 7b of the intermediate member 7, and in this state, the torque bolt 8 screwed to one side of the coupler 5 is When rotated, the end of the torque bolt 8 enters the inside of the coupler 5 to squeeze the reinforcing bar 6 to the lower side of the intermediate member 7 while digging into the surface of the reinforcing bar 6, and the torque bolt 8 is tightened. If the rotation continues with a predetermined force or more, the head of the torque bolt 8 is broken and the end of the reinforcing bar 6 is in the coupler 5. Silhage is fixed.

그러나, 상기의 철근 연결구는 중간부재(7)를 필요로 하기 때문에 제조단가가 상승됨과 아울러 중간부재(7)를 커플러(5) 내로 진입시켜 상호 나사결합시키는데 많은 노력이 소요되며, 커플러(5)의 암나사부(5a)나 중간부재(7)의 숫나사부(7a)가 손상된 경우에는 중간부재(7)와 커플러(5)를 나사 결합시킬 수 없는 문제점이 발생된다.However, since the reinforcing bar connector requires the intermediate member 7, the manufacturing cost is increased and a lot of effort is required to enter the intermediate member 7 into the coupler 5 and to screw each other, and the coupler 5 If the female screw portion 5a or the male screw portion 7a of the intermediate member 7 is damaged, the intermediate member 7 and the coupler 5 cannot be screwed together.

또한, 띠철근을 호형상으로 연결시키기 위하여 철근이음구가 호형상으로 구부러진 경우에는 중간부재를 호형상의 커플러에 나사 결합시킬 수 없기 때문에 호형 띠철근의 연결이 불가능한 문제점이 있었다.In addition, when the reinforcing bar is bent into an arc shape in order to connect the band reinforcing in the arc shape, there is a problem that the arc-shaped band reinforcing bar cannot be connected because the intermediate member cannot be screwed to the arc-shaped coupler.

본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 토크볼트를 이용한 철근이음구의 제조단가를 저감시킴과 아울러 철근의 이음작업을 간편하게 할 수 있고, 띠철근을 호형으로 이어줄 수 있는 철근이음구를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and can reduce the manufacturing cost of the reinforcing bar using the torque bolt, and can simplify the joint operation of the reinforcing bar, it can lead the band reinforcement arc The purpose is to provide a reinforcing bar.

It fits into the bone 11 and the projection 32 of the reinforcing bar 10 fits into the lateral valleys 12 of the coupler 10. Then, when the torque bolt 20 is rotated, the end of the torque bolt 20 squeezes the reinforcing bar 30 in the downward direction while digging the surface of the reinforcing bar 30 so that the reinforcing bar 30 is firmly fixed to the coupler 10. do. At this time, when the torque bolt 20 is rotated by a predetermined force or more, the head of the torque bolt 20 is broken and separated from the bolt part.

미설명 부호 20a 는 두부가 분리된 토크볼트를 나타낸다.Reference numeral 20a denotes a torque bolt with the head separated.

본 발명의 다른 실시예가 도시된 도 8에 따르면, 본 발명의 철근이음용 커플러(10')는 호형상으로 약간 휘어져 띠철근(30')을 호형상으로 이어주도록 형성되어 있다.According to FIG. 8, which shows another embodiment of the present invention, the coupler 10 ′ of the present invention is slightly curved in an arc shape and is formed to connect the band reinforcing bar 30 ′ to the arc shape.

본 발명의 또다른 실시예가 도 9에 도시되어 있다.Another embodiment of the invention is shown in FIG.

도 9에 도시된 본 발명은, 커플러(40)의 내부구조는 상기한 실시예와 동일하고 토크볼트(50)가 커플러(40)에 2열로 복수개 배열되어 있어, 토크볼트가 일열로 배열된 다른 실시예에 비하여 커플러(40)의 길이를 짧게 형성할 수 있다.In the present invention shown in Figure 9, the internal structure of the coupler 40 is the same as the above embodiment and the torque bolt 50 is arranged in a plurality of two rows in the coupler 40, other torque bolts are arranged in one row Compared to the embodiment, the coupler 40 may have a shorter length.

이와 같이, 본 발명은 중공의 커플러와 상기 커플러에 나사 결합된 토크볼트로 구성된 철근이음구에 있어서, 상기 커플러 내면에 철근의 보강마디와 돌조가 각각 끼워질 수 있는 횡방향 골과 종방향 골의 직접 형성되어 있기 때문에 철근이음구의 제조단가를 절감함과 아울러 토크볼트를 이용하여 철근을 간편하게 커플러에 고정시켜 철근을 서로 이어줄 수 있고, 직선상의 원통형 커플러를 호형으로 휘어지게 함으로써 띠철근을 호형상으로 이어줄 수 있는 효과가 있다.As described above, the present invention is a reinforcing bar consisting of a hollow coupler and a torque bolt screwed to the coupler, the reinforcement node of the reinforcing bar and the projection of the longitudinal bone can be fitted directly into the coupler inner surface respectively Since it is formed, it is possible to reduce the manufacturing cost of the reinforcing bar and to fix the rebar to the coupler easily by using the torque bolt to connect the reinforcing bars to each other, and to make the band reinforcing into the arc shape by bending the straight cylindrical coupler into the arc shape.
