본 발명은 철근 연결구에 관한 것으로, 보다 상세히는 연결하고자 하는 철근을 보다 간편하게 연결함으로서 철근콘크리트 시공 작업에 대한 효율성을 향상시킬 수 있도록 구성된 철근 연결구에 관한 것이다.The present invention relates to a reinforcing bar connector, and more particularly, to a reinforcing bar connector configured to improve the efficiency of the reinforced concrete construction work by connecting the reinforcing bars more easily.

일반적으로 철근콘크리트는 철근과 콘크리트의 결합구조로서, 콘크리트가 압축력을 부담하고 철근이 인장력을 부담하는 구조이다.In general, reinforced concrete is a combined structure of reinforcing steel and concrete, and the concrete bears the compressive force and the steel bears the tensile force.

철근콘크리트 구조는 철근 배근 후 거푸집을 설치하고 이에 콘크리트를 타설하여 일체형으로 시공하게되는데, 시공과정에서 철근은 필요에 따라 일정길이의 규격품을 서로 이어가며 시공하야 하는바, 철근과 철근간에는 당연히 조인트부가 발생하게된다.Reinforced concrete structure is installed as a form after reinforcing the reinforcement and cast concrete and install it in one piece. Will occur.

이러한 철근과 철근 사이에 형성된 조인트부에서는 콘크리트의 양생과정에서 발생하는 소정의 인장력이 작용하게된다.In the joint portion formed between the reinforcing bars and the reinforcing bar is a predetermined tensile force generated during the curing process of the concrete.

이러한 인장력에 충분히 대응하기 위해서는 철근 상호간에 긴밀한 연결 상태가 유지되어야하며, 여기에는 통상 겹침이음 또는 압접등의 방법이 적용되고 있다.In order to cope with such tensile force sufficiently, a close connection between the bars must be maintained, and a method such as a lap joint or a pressure welding is generally applied thereto.

상기 겹침 이음은 철근과 철근을 소요 이음길이 이상으로 겹쳐서 배근하고 결속선으로 묶는 방식이다.The overlapping joint is a method of reinforcing the reinforcing bars and reinforcing the reinforcing bars over the required joint length and tied with a binding line.

이는 배금작업이 용이한 장점은 있으나 철근의 직경이 큰 경우에는 편심에 의해 철근의 응력집중이 일치되지 않아 구조 내력상의 문제가 있고, 콘크리트부재가 얇은 경우에는 겹쳐진 철근 때문에 거푸집의 단면이 좁아져 콘크리트 타설이 용이하지 않으며 철근의 배근 각격과 콘크리트의 최소 피복두께를 유지하기 어렵다는 문제점이 있다.This has the advantage of easy distribution, but when the diameter of the reinforcing bar is large, the stress concentration of the reinforcing bars is not matched by the eccentricity, which causes problems in structural strength, and when the concrete member is thin, the cross section of the formwork is narrowed due to the overlapping reinforcing concrete. It is not easy to pour and there is a problem that it is difficult to maintain the reinforcement angle of the rebar and the minimum coating thickness of the concrete.

또한, 압접에 의한 철근 이음방법은 철근과 철근의 단부를 이어서 맞댄 후 가열하면서 압착하여 단부를 일체로 연결하는 방법이다.In addition, the method of connecting the reinforcing bars by pressure welding is a method of connecting the ends integrally by pressing together with the ends of the reinforcing bars and the reinforcing bars and then pressing while heating.

그런데, 이러한 압접에 의한 철근 이음방법은 작업시간이 길고 철근에 직접 열을 가하게됨으로 철의 성질이 변화되며, 열의 식는 속도에 따라 강도가 저하되는 등의 많은 문제점이 있어 이를 적용하기 쉽지 않다.By the way, the method of connecting the reinforcement by the pressure welding is a long time and the heat is directly applied to the rebar, the properties of the iron is changed, there are many problems such as the strength decreases depending on the cooling rate of the heat is not easy to apply this.

이에, 상기 겹침이음 및 압접에 의한 철근 이음방식에서 발생하게 되는 문점점을 해결하기 위하여 종래에는 철근과 철근을 기계적으로 결합하는 연결하는 철근 연결구가 다양하게 제안되어 사용되고 있다.Accordingly, in order to solve the problems caused in the reinforcement joint method by the overlapping joint and the pressure welding, a conventional reinforcing bar connector connecting mechanically connecting reinforcing bars and rebars has been proposed and used.

첨부도면 도 1a 및 도 1b는 종래에 통상적인 철근 연결구를 나타낸 사시도 및 단면도.1A and 1B are a perspective view and a cross-sectional view showing a conventional reinforcing bar connector.

도시한 바와 같은 종래의 통상적인 철근 연결구(1)는 크게 커플러(10)와 이의 양측에 체결되는 너트(20)로 구성된다.The conventional conventional reinforcing bar connector 1 as shown is largely composed of a coupler 10 and a nut 20 fastened to both sides thereof.

상기 커플러(10)는 전체적으로 원통형구조로 이루어져 있으며, 중앙의 몸통 부(11)와 이의 양단에 위치한 잠금부(12)로 구분된다.The coupler 10 has a cylindrical structure as a whole, and is divided into a central body part 11 and a locking part 12 located at both ends thereof.

상기 몸통부(11)의 내주면에는 철근(2)이 체결되는 암나사(11a)가 형성되어 있어 이 암나사(11a)에 철근(2)의 단부에 형성된 나사부(2a)를 나사 결합시킴으로써 두 개의 철근(2)을 서로 이을 수 있게된다.The inner circumferential surface of the body portion 11 is formed with a female screw 11a to which the reinforcing bar 2 is fastened, thereby screwing the two threaded bars 2a formed at the end of the reinforcing bar 2 to the female screw 11a. 2) can be connected to each other.

상기 잠금부(12)의 내경은 몸통부(11)의 내경 보다 크게 형성되어 있고, 끝단 방향으로 갈수록 점차적으로 가늘어지게 경사진 구조로 이루어지며, 그 외주면에는 상기 너트(20)가 나사 결합되는 수나사(12a)가 형성되어 있다.The inner diameter of the locking portion 12 is formed larger than the inner diameter of the body portion 11, it is made of a structure that is inclined gradually tapered toward the end direction, the outer peripheral surface of the male screw is screwed 12a is formed.

또한, 상기 잠금부(12)의 둘레면에는 너트(20)의 체결 시 내경 방향으로 조여지도록 그 길이방향을 따라 다수의 절개홈(12b)이 형성되어 있다.In addition, a plurality of cutout grooves 12b are formed in the circumferential surface of the lock part 12 along its longitudinal direction so as to be tightened in the inner diameter direction when the nut 20 is fastened.

이러한 종래의 철근 연결구(1)를 이용한 철근(2)의 이음과정을 살펴보면, 먼저 연결할 각각의 철근(2) 단부를 깍아 소정 지름의 나사부(2a)를 형성하는 단계로부터 시작된다.Looking at the joint process of the reinforcing bar (2) using the conventional reinforcing bar connector (1), first begins by cutting the end of each reinforcing bar (2) to be connected to form a screw portion (2a) of a predetermined diameter.

상기 각각의 철근(2) 단부에 나사부(2a)가 형성되면, 이를 나사부(2a)가 서로 마주보도록 두 철근(2)을 일렬로 정렬한 다음, 이를 커플러(10)의 양방에서 내측으로 철근(2)을 돌려 끼우면서 상기 각 나사부(2a)를 커플러(10) 내부의 암나사(11a)에 체결하게 된다.When the threaded portion 2a is formed at each end of the reinforcing bar 2, the two reinforcing bars 2 are aligned in a line so that the threaded parts 2a face each other, and then the reinforcing bars (in both sides of the coupler 10) are inward. 2) by screwing each screw portion (2a) to the internal thread (11a) of the coupler (10).

이어서, 상기 잠금부(12) 표면의 수나사(12a)에 너트(20)를 체결하여 조여주면, 상기 잠금부(12)의 내경이 수축하면서 철근(2)의 마디와 마디 및 리브를 압착하게되어 두 개의 철근(2)이 서로 연결되는 것이다.Subsequently, when the nut 20 is fastened and tightened to the external thread 12a on the surface of the locking part 12, the inner diameter of the locking part 12 is contracted, and the nodes, nodes and ribs of the reinforcing bar 2 are compressed. Two reinforcing bars (2) are connected to each other.

그러나, 이와 같은 종래의 철근 연결구(1)는 연결되는 철근(2)의 단부를 깍 아서 나사부(2a)를 형성해야 함으로 철근을 이음하기 위한 공정수가 늘어나 작업능률이 저하됨은 물론 그 구조가 복잡함으로 제작이 용이하지 못하다는 문제점이 있었다.However, such a conventional reinforcing bar connector (1) by cutting the end of the reinforcing bar (2) to form a screw portion (2a) to increase the number of processes for joining the rebar increases work efficiency is lowered as well as its structure is complicated There was a problem that the production is not easy.

또한, 종래의 철근 연결구(1)는 연결하고자 하는 철근(2)의 단부에 나사부(2a)를 형성하는 관계로 철근(2)의 단부 면적이 축소되기 때문에 그로 인해 철근(2) 이음부위에서의 인장강도가 저하되어 콘크리트의 양생과정에서 발생되는 인장력에 의해 철근(2)의 이음 단부가 끊어지는 등의 문제점이 있었다.In addition, the conventional reinforcing bar connector (1) is formed in the end of the reinforcing bar (2) because the end area of the reinforcing bar 2 is reduced due to the formation of the threaded portion (2a) at the end of the reinforcing bar (2) to be connected There was a problem that the joint end of the reinforcing bar (2) is broken by the tensile force generated in the curing process of the concrete is lowered tensile strength.

본 발명은 상기한 바와 같은 문제점에 착안하여 제안된 것으로, 그 목적은 연결하고자 하는 철근을 커플러의 단부에 진입시키기만 하면 철근의 연결작업이 신속하게 완료되도록 함으로써 철근콘크리트 시공 작업에 대한 효율성을 향상시킬 수 있도록 구성된 철근 연결구를 제공 하고자 하는 것이다.The present invention has been proposed in view of the problems described above, the object of which is to improve the efficiency of the reinforced concrete construction work by allowing the connection of the reinforcing bar is completed quickly just to enter the end of the coupler to be connected to the rebar It is intended to provide a reinforcing bar connector that can be configured.
