Description

철근 연결구{Reinforcing bar coupler}{Reinforcing bar coupler}

본 발명은 건설 현장에 매설되는 철근들 사이를 견고하게 이어주는 것으로, 보다 상세하게는 원통부에 형성된 요홈에 철근의 돌출부위가 어느 방향에서도 쉽게 결합되도록 할 뿐 아니라 간단한 조작에 의해 견고하게 철근이 연결되도록 구성을 단순화시켜 제작 비용이 저렴하고, 제품의 신뢰성도 향상되도록 하는 철근 연결구에 관한 것이다.The present invention relates to a structure for reinforcing reinforcing bars embedded in a construction site. More particularly, the present invention relates not only to a protruding portion of a reinforcing bar in a groove formed in a cylindrical portion, So as to simplify the construction so that the manufacturing cost is low and the reliability of the product is improved.

각종 건설현장에서 콘크리트 구조물에 사용하기 위한 철근을 연결하기 위해서 종래에는 철근을 이중으로 겹친 상태에서 철사 등으로 묶어서 고정하였으나, 이러한 철근 고정방식은 작업자가 철사를 다수 회 철근 외주로 권취한 다음 묶어야 하므로 작업이 번거롭고 철근의 중심이 수직이 되지 않고 삐뚤어질 뿐 아니라 철사의 강도가 약하기 때문에 쉽게 끊어지면서 연결상태가 해제되는 문제점이 있었다.Conventionally, in order to connect reinforcing bars for use in concrete structures in various construction sites, reinforcing bars are conventionally bundled and fixed in a double layer structure. However, in this reinforcing bar fixing method, an operator has to wire the reinforcing bars around the reinforcing bars a plurality of times The work is troublesome and the center of the reinforcing bar is not vertical and is not straight, but the strength of the wire is weak, so that it is easily broken and the connection state is released.

이러한 문제점을 해결하기 위하여 철근을 철사가 아닌 다른 수단으로 쉽고 단단하게 연결하기 위한 철근 연결구들이 개발되어 사용되고 있다.In order to solve these problems, reinforcing bar joints have been developed and used for easily and rigidly connecting reinforcing bars by means other than wires.

이러한 종래 연결구조체는 조립 시간이 적도록 한 구성은 비교적 가격이 너무 비싸고, 저렴하게 구성한 것은 조립하는 것이 조잡하여 시간이 너무 많이 걸리고 결합상태 또한 신뢰성이 낮은 문제점이 있었다.Such a conventional connection structure has a problem that the assembly time is short and the assembly is relatively expensive and the assembly is inexpensive.

이러한 본 발명은 고정볼트(30)를 고정판(20)의 구멍을 통해 삽입시켜 고정너트(31)와 체결하면 상측 고정판(20)과 하측 고정판(20)이 밀착되고, 원통부(10)에 삽입된 철근(1)이 견고하게 고정된다.In the present invention, when the fixing bolt 30 is inserted through the hole of the fixing plate 20 and is fastened to the fixing nut 31, the upper fixing plate 20 and the lower fixing plate 20 come into close contact with each other, The reinforced bar 1 is firmly fixed.

고정볼트(30)는 회전방지턱(21)에 육각 머리 일부가 밀착되어 공회전이 방지되게 된다.A part of the hexagon head of the fixing bolt 30 is closely attached to the rotation stopping jaw 21 to prevent idling.

한편, 도 8은 본 발명의 다른 실시예를 나타내는 것으로, 원통부(10)의 내주면에 소정 간격을 두고 축 방향 요홈부(a')가 복 수개 형성되고, 요홈부(a')에 상대적으로 돌출되게 돌출부에 나선형의 돌기(b')와 횡 요홈(c')이 연속 형성된다.8 shows another embodiment of the present invention. A plurality of axial grooved portions a 'are formed at predetermined intervals on the inner circumferential surface of the cylindrical portion 10, and a plurality of axial grooved portions a' The projections b 'and the transverse grooves c' are continuously formed on the protrusions so as to protrude.

이러한 본 발명의 다른 실시예는 외주면에 나선형 돌출부가 형성되는 철근을 연결하기 위한 것으로, 철근 외주면의 나선형 돌출부가 원통부(10) 내주면의 나선형 돌기(b')들 사이에 끼워지고, 철근 외주면에 축 방향으로 나선형 돌출부가 원통부(10) 내주면의 축 방향 요홈부(a')들에 선택적으로 끼워져 결합이 용이하고, 결합 후 결합상태가 견고하도록 한다.Another embodiment of the present invention is for connecting a reinforcing bar having a spiral protrusion formed on the outer circumferential surface thereof. The helical protrusion of the reinforcing bar outer circumferential surface is sandwiched between the helical protrusions b 'of the inner circumferential surface of the cylindrical portion 10, The spiral projection in the axial direction is selectively inserted into the axial direction recessed portions a 'of the inner circumferential surface of the cylindrical portion 10 so that the engagement is easy, and the engagement state after the engagement is made firm.
