Description

관재(管材)의 접합수단 및 접합방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도와 제2도는, 본 발명의 특징에 따라 접합부의 구조를 설명하는 일부절결 정면도, 제3도는, 접합후의 관재와 관 연결부를 요(凹)부의 중심을 통하는 평면(A-A단면)에서 절단한 단면도, 제4도는 본 발명의 다른 형태를 나타내는 일부 절결 정면도이다.

Claims (5)

  1. 접합하고자하는 관재(1)와 대략 동일자 지름을 갖는 주부재(3)의 적어도 한쪽단부에 환상돌출부(5)와 제1확경부(4)를 갖는 것과 동시, 환상돌출부(5)보다 내측에 접합하고져하는 관재(1)의 외주와의 사이에 간격부식을 방지하기에 충분한 간격(9)을 형성하고 제2확경부(6)를 갖고 있는 것을 특징으로하는 관 연결구(2).
  2. 제1확경부(4)선단에 테이퍼상부(7)를 형성하여서 되는 것을 특징으로 하는 청구의 범위 제1항 기재의 관연결구(2).
  3. 제1확경부(4)가, 환상돌출부(5)를 기점으로하여, 환상돌출부(5)부터 제2확경부(6)의 끝까지의 거리(L1)와 같은 거리(L2)의 위치에 요(凹)부(13)를 형성시킬 수가 있는 길이를 갖는 것을 특징으로하는 청구의 범위 제1항 또는 제2항에 기재한 관 연결구(2).
  4. 청구의 범위 제1항 내지 제3항의 어느 한항 기재의 관 연결구(2)의 환상돌출부(5)내에 기밀재(8)를 감삽한 후 접합하고져하는 관재(1)를 제2확경부(6)까지 삽입하고, 이어서 관 연결부 (2)의 외주를 환산돌출부(5)의 적어도 최대의경부와 제1확경부(4)의 일부를 가압하나, 제2확경부(6)는 가압하지 않는 압축공구(10)에 의하여 가압하고, 기밀재(8)를 압박하여 관 연결구 (2)와 접합하고자하는 관재(1)와의 사이에 기밀을 유지함과 동시, 접합하고자하는 관재(1)에 물고드는 복수개의 요(凹)부(13)를 제1확경부(4)의 주연으로 형성하는 것을 특징으로 하는 관재의 접합방법.
  5. 관 연결구 (2)의 환상돌출부(5)를 기점으로하여, 제2확경부(6)의 끝까지의 거리(L1)와 제1확경부(4)에 형성되는 요(凹)부(13)의 앞단까지의 거리(L2)를 동일하게 한 것을 특징으로 하는 청구의 범위 제4항 기재의 관재의 접합방법.
