Abstract

본 발명은 철근 콘크리트조 또는 철골 철조 콘크리트조등을 이용하는 구조물시공에 있어서 단부 이형철근의 단부 부풀림 나사 내기식 철근 이음공법에 관한 것으로서, 충전식 이음법은 충전재 경화시까지 철근 이음부가 보호 양생되어야 하고 충전용 슬리브의 직경이 과도하게 되며, 압착식 이음의 경우 작업이 복잡하고 품질검사가 난해하며, 나사식 이음의 경우 이음부의 강도저하, 슬립, 시공시간이 길어지는 등의 종래 기계적 철근 이음법의 문제점을 해결하기 위하여, 철근의 단부를 필요한 직경의 금형내에서 열간단조 가공하여 부풀린 후 이를 로링 가공에 의해 숫나사를 만들고 여기에 체결될 암나사를 내면에 가진 이음용 케플러에 의한 접속후 케플러의 일단에 배치한 와셔와 로크너트에 토오크를 주어 체결하여서 된 것이다.The present invention relates to an end swelling screw end reinforcing bar joint method of the end deformed reinforcing bar in the construction of a structure using a reinforced concrete tank or a steel steel concrete concrete, the filling joint method is to be cured reinforcement of the reinforcement joint until the filler hardening The diameter of the sleeve is excessive, and the crimped joint is complicated in work and difficult to inspect, and in the case of threaded joints, problems of the conventional mechanical reinforcing bars such as reduced strength of the joint, longer slip, and longer construction time are required. In order to solve the problem, the end of the rebar is inflated by hot forging in a mold of the required diameter, and then made into a male thread by a roring process, and a female screw to be connected thereto is connected to the end of the Kepler by a joint Kepler having an internal thread. This was done by giving a torque to a washer and a lock nut.

Description

이형철근의 단부 부풀림 나사 내기식 철근이음 공법End swelling screw of internal rebar

Claims (2)

접속할 2개의 이형철근(1)의 단부를 소정의 굵기로 열간 부풀림 단조 가공한 뒤에 로링으로 숫나사를 만들고, 여기에 체결된 암나사를 내면에 가진 이음용 케플러(10)에 의한 접속후, 케플러(10)의 일단에 배치한 와셔(12)와 로크 너트(11)에 토오크를 주어 체결하는 것을 특징으로 하는 이형철근의 단부 부풀림 나사 내기식 철근 이음공법.After the ends of the two deformed steel bars 1 to be connected are hot swelled and forged to a predetermined thickness, a male screw is made by a ring ring, and the connection is made by a joint Kepler 10 having a female screw fastened thereto, and then a Kepler 10 Torque is tightened by giving a torque to the washer 12 and the lock nut 11 arranged at one end of the). 제 1 항에 있어서, 이형철근(1)에 열간 부풀림 단조가공 및 로링에 의한 숫나사 가공이후의 나사의 골지름에 의한 단면적이 가공전 이형철근의 단면적보다 크게하여 이음부의 강도가 철근 모재의 강도보다 크게＋하는 것을 특징으로 하는 이형철근의 단부 부풀림 나사 내기식 철근 이음공법.The cross section of the thread diameter of the screw after the male thread processing by hot swelling forging and rolling in the deformed bar 1 is larger than that of the deformed bar before processing, so that the strength of the joint is greater than that of the reinforcing base material. End swelling screw internal reinforcing bar joint method of the deformed steel bar characterized by greatly +. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
