Description
본 고안은 철근의 연결구조에 관한 것으로, 더욱 상세하게는 양측으로 대칭을 이루게 암나사를 형성한 연결소켓에 나사 결합되는 철근의 연결구조에 있어서 상기 연결소켓과 철근의 나사부를 인장나사부와 조임나사부로 구성하여 그 결속이견고하고 안전하게 이루어지도록 함을 목적으로 한 것이다.The present invention relates to a connecting structure of reinforcing bars, and more particularly, in the connecting structure of reinforcing bars screwed to connecting sockets formed with female threads to be symmetrical on both sides, the connecting sockets and reinforcing thread parts as tension screw parts and tightening screw parts. The purpose is to make the bond solid and safe.
일반적으로, 고층 건축물이나 대형 건축물 등과 같은 콘크리트 구조물에는 인장강도와 진동 및 충격 등에 대한 저항을 증대시키기 위하여 내부에 철근을 넣어 시공하고 있다.In general, concrete structures such as high-rise buildings and large buildings are constructed by putting reinforcing bars in order to increase resistance to tensile strength, vibration, and impact.
상기한 바와 같이 콘크리트 구조물에 사용되는 철근은 운반 및 사용의 편리성을 위하여 일정한 크기로 재단되어 있어 사용시는 일정 길이로 재단된 철근을 맞대어 와이어로 결박하거나 용접 등에 의하여 융착시켜 사용하였다.As described above, the rebar used in the concrete structure is cut to a certain size for convenience of transportation and use, and when used, it is used by gluing the bar by using a wire or by welding the steel bars cut to a certain length.
그러나, 상기한 바와 같이 와이어로 결박하여 철근을 결속하는 방법은 와이어가 외력에 의하여 쉽게 절단되거나, 시멘트 몰탈에 함유된 수분에 의하여 부식되어 철근의 결속상태가 해제되는 등의 문제점이 있고, 용접과 같은 융착에 의한 방법은 용접부위가 가공 경화되어 외력에 의하여 쉽게 파손되며, 충분한 작업공간이 확보되지 않으면 작업이 용이하지 못한 문제점이 있어다.However, as described above, the method of binding the reinforcing bar by binding with the wire has a problem such that the wire is easily cut by external force or corroded by moisture contained in cement mortar to release the binding state of the rebar. In the same fusion method, the welded part is easily hardened by external force due to work hardening, and there is a problem in that work is not easy unless sufficient working space is secured.
이에, 국내 특허 출원된 98-50486호에 소개된 바와 같이 양단에 테이퍼지게 암나사부(51)를 형성한 연결소켓(50)을 구비하고, 연결하고자 하는 철근(60)의 단부에 각각 테이퍼지게 수나사부(61)를 형성한 후 상기 연결소켓(50)을 이용하여 철근(60)을 나사 결속에 의하여 견고하고 용이하게 연결할 수 있도록 한 기술이 개발되어 사용되고 있다.Thus, as described in the Korean Patent Application No. 98-50486, it has a connecting socket 50 having a female threaded portion 51 tapered at both ends, and can be tapered at each end of the rebar 60 to be connected. After the formation of the screw portion 61, the technology has been developed and used so that the reinforcement 60 can be firmly and easily connected by screw binding using the connecting socket 50.
그러나, 상기한 바와 같이 양단에 테이퍼지게 암나사부(51)를 형성한 연결소켓(50)을 구비하고, 연결하고자 하는 철근(60)의 단부에 테이퍼지게 수나사부(61)를 형성하여 나사 결속한 종래 철근의 연결구조는 작업과정에 연결소켓(50)의 암나사부(51)에 철근(60)의 수나사부(61)가 견고하게 물리지 않고 조금이라도 이격되게되면 테이퍼 나사의 특성상 나사부(51,61)의 산끝과 끝 만이 맛물려 작은 인장력에도 그 결합상태가 해제되는 등의 문제점이 있었다.However, as described above, the connection socket 50 having the female threaded portion 51 tapered at both ends is provided, and the male threaded portion 61 is tapered at the end of the reinforcing bar 60 to be connected, and the screw is engaged. Conventional reinforcing bar connection structure is the threaded portion (51, 61) due to the nature of the tapered screw when the male threaded portion 61 of the reinforcement 60 is not firmly bitten by the female threaded portion 51 of the connecting socket 50 in the process of working Only the tip and the tip of the mountain) was tasted, there was a problem such that even the small tensile force is released.
이에, 본 고안은 상술한 문제점을 해결하기 위하여 안출한 것으로, 연결소켓의 암나사부와 철근의 수나사부를 인장나사부와 조임나사부로 형성하여 그 결속이 견고하면서도 안전하게 결속되도록 한 것이다.In this regard, the present invention has been made to solve the above-mentioned problems, the female threaded portion of the connecting socket and the male threaded portion of the reinforcing bar is formed by the tension screw portion and the tightening screw portion to ensure that the binding is solid and secure.

The rebar 20 has an end portion of the male screw portion 21 which is horizontal to form a tensile male screw portion 21b which is screwed with the tensile female screw portion 11b of the connecting socket 10, and the tensile male screw portion 21b of A taper is formed on the inner side to continuously form a tightening screw portion 21a which is screwed to the tightening female screw portion 11a of the connecting socket 10.
한편, 본 고안의 실시예 있어서 초기 결합시 나사 결합되는 철근(20)의 인장 수나사부(21b)와 연결소켓(10)의 인장암나사부(11b)가 용이하게 나사 결합되도록상기 철근(20)의 인장수나사부(21b) 단부에 테이퍼지게 형성한 결합유도부(21c)를 형성하여 실시할 수 있는 것이다.On the other hand, in the embodiment of the present invention so that the tension male screw portion 21b of the reinforcing bar 20 is screwed during the initial coupling and the tension female screw portion 11b of the connecting socket 10 is easily screwed to the The coupling guide portion 21c tapered at the end portion of the tension male screw portion 21b can be formed.
이하, 본 고안의 사용과정에 대하여 설명하면 다음과 같다.Hereinafter, the use process of the present invention will be described.
상기한 바와 같이 연결소켓(10)과 철근(20)의 나사부(11,21)를 인장나사부(11b,21b)와 조임나사부(11a,21a)로 형성한 본 고안은 시공현장에서 철근(20)의 단부에 다이스기계를 이용하여 수평을 이루는 인장수나사부(21b)를 가공 형성하고, 그 내측으로 축소확대되게 테이퍼를 이루는 조임수나사부(21a)를 가공 형성한다.As described above, the present invention in which the threaded portions 11 and 21 of the connecting socket 10 and the reinforcing bar 20 are formed as the tension screw portions 11b and 21b and the tightening screw portions 11a and 21a is constructed as a reinforcing bar 20 at a construction site. The tension male screw portion 21b is formed at the end of the die by using a die machine, and the threaded screw portion 21 a is tapered to be tapered inwardly.
이상과 같이 철근(20)에 수나사부(21)의 형성이 완료되면 철근(20)을 이용하여 콘크리트구조물의 골격을 형성한다. 이때, 골격을 이룬 철근(20)에 새로운 철근(20)을 연결하여 사용하고자 할 경우에는 연결하고자 하는 철근(20)에 연결소켓(10)을 끼워 결합한다.When the male thread portion 21 is formed on the rebar 20 as described above, the skeleton of the concrete structure is formed by using the rebar 20. At this time, when the new reinforcing bar 20 is to be used to connect to the reinforcing bar 20 made of a skeleton, the connecting socket 10 is fitted to the reinforcing bar 20 to be connected.
상기한 바와 같이 철근(20)에 연결소켓(10)을 끼워 결합하면 철근(20)의 인장수나사부(21b)가 연결소켓(10)의 조인암나사부(11)보다 직경이 작으므로 쉽게 가 결합이 이루어진다.As described above, when the connecting socket 10 is fitted to the reinforcing bar 20, the tension male screw part 21b of the reinforcing bar 20 is smaller in diameter than the joining female screw part 11 of the connecting socket 10. This is done.
이상과 같이 철근(20)에 연결소켓(10)이 가 결합된 상태에서 상기 연결소켓(10)을 돌려주면 우선 인장수나사부(21b)가 인장암나사부(11b)에 나사 결합되게되고, 상기 인장수나사부(21b)의 나사 결합이 완료되는 시점에서 테이퍼지게 형성된 조임수나사부(21a)가 조임암나사부(11a)에 나사 결합되게 되는데 이때, 테이퍼 나사의 특성상 조임나사부(11a,21a)가 견고하게 조임결합되게 되는 것이다.When the connecting socket 10 is rotated in the state in which the connecting socket 10 is coupled to the rebar 20 as described above, the tension male screw portion 21b is first screwed into the tension female screw portion 11b, and the tension When the screwing of the male screw portion 21b is completed, the tightening screw portion 21a formed to be tapered is screwed to the tightening female screw portion 11a. At this time, the tightening screw portions 11a and 21a are firmly fixed due to the characteristics of the tapered screw. It will be tightened.
한편, 상기한 바와 같은 연결소켓(10)의 나사 결합과정에 있어 그 결합이 완벽하게 이루어지지 않아 조임나사부(11a,21a)의 결속이 헐겁게 되어도 인장나사부(11b,21b)가 그 결합상태를 유지하므로 철근(20)의 결속상태가 견고하게 유지되는 것이다.On the other hand, in the screw coupling process of the connection socket 10 as described above, even if the tightening of the tightening screw parts (11a, 21a) is loosened, the tension screw parts (11b, 21b) maintains the coupling state Therefore, the binding state of the reinforcing bar 20 will be maintained firmly.
상기한 바와 같이 골격을 이루고 있는 철근(20)의 단부에 연결소켓(10)을 결합한 상태에서 상기 연결소켓(10)에 연결하고자 하는 철근(20)을 나사 결합하므로써 상술한 바와 같은 과정을 통하여 그 결합이 견고하게 이루어지는 것이다.Through the process as described above by screwing the reinforcing bar 20 to be connected to the connecting socket 10 in a state in which the connecting socket 10 is coupled to the end of the reinforcing bar 20 forming the skeleton as described above The bond is solid.
따라서, 본 고안은 연결소켓과 철근의 나사부를 인장나사부와 조임나사부로 형성하므로서 연결소켓과 철근의 나사 결합이 완벽하게 결속되지 않은 상태에서도 인장나사부가 그 결속상태를 유지하므로 그 결속상태의 안정성이 확보되는 것이다.Therefore, the present invention forms the threaded portion of the connecting socket and the reinforcing bar with the tension screw portion and the tightening screw portion, so that the tensioned screw part maintains the binding state even when the screw connection of the connecting socket and the reinforcing bar is not completely engaged, so that the stability of the tied state is maintained. It is secured.
또한, 결합과정에 있어 인장수나사부가 조임암나사부보다 직경이 작으므로 초기 조립과정에 있어 그 결속이 용이하게 이루어지는 매우 유용한 것이다.In addition, since the tension male screw portion is smaller in diameter than the tightening female screw portion in the joining process, it is very useful that the binding is easily performed in the initial assembly process.
