Abstract

본 발명은 결합부분의 수구가 확관을 이루는 조립식 강관전주와 그 제조방법에 관한 것으로서, 기준강도 이상의 휨응력을 가지고 경제성 및 작업성을 확보할 수 있도록 수구가 확관형태를 취하고 다단식으로 조립될 수 있는 강관전주와 그 제조방법을 제공하기 위하여, 소경의 전주단체 일단이 대경의 전주단체 삽입구에 결합 가능하게 확관을 이루는 수구로 구성하고, 상기 전주단체는 강관의 확관부를 200。C로 가열하고 1차로 비교적 소경의 다이스에 50。C기준 동점도 90이상의 인발유를 도포하여 상기 확대부내로 전진시킨 후 어프로치 외곽의 상기 강관표면에 300~450。C로 가열하여 상기 소경의 다이스를 후퇴시키고, 2차로 비교적 대경의 다이스를 이용해 상기와 동일과정을 거쳐 상온에서 냉각시키도록 한 것이다.The present invention relates to a prefabricated steel pipe pole and a method of manufacturing the same, the water pipe of the coupling portion is expanded, the water pipe can be assembled in a multi-stage and take the expansion pipe shape so as to secure economic efficiency and workability with a bending stress of more than the reference strength. In order to provide Jeonju and its manufacturing method, one small Jeonju organization consists of a water duct that can be expanded to the Daejeon Jeonju insertion slot, and the Jeonju organization heats the expansion pipe of the steel pipe to 200 ° C Apply a drawing oil having a kinematic viscosity of 90 ° or higher at a relatively small diameter die and advance it into the enlarged part, and then heat the steel pipe surface at a temperature of 300 to 450 ° C outside the approach to retreat the small diameter die. Cooling at room temperature through the same process as above using a large diameter die.

Claims (4)

소경의 전주단체 일단이 대경의 전주단체 삽입구에 결합가능하게 확관을 이루는 수구로 구성되는 조립식 강관전주.Pre-assembled steel pipe Jeonju is a prefabricated steel pipe Jeonju consisting of a water pit that can be expanded to the entrance of Daekyung Jeonju organization. 제1항에 있어서, 대경의 전주단체 삽입구에 길이방향으로 안내돌기를 형성시키고 소경의 전주단체 수구에 상기 안내돌기와 결합가능한 결합돌기를 형성시킨 조립식 강관전주.The prefabricated steel pipe pole according to claim 1, wherein a guide protrusion is formed in a longitudinal direction at a large diameter electric pole insertion hole, and a coupling protrusion capable of engaging with the guide protrusion is formed at a small diameter electric pole body port. 강관의 확관부를 200˚C로 가열하고 1차로 비교적 소경의 다이스에 50˚기준 동점도 90이상의 인발유를 도포하여 상기 확관부내로 전진시킨 후 어프로치 외곽의 상기 강관표면에 300~450˚C로 가열하여 상기 소경의 다이스를 후퇴시키고, 2차로 비교적 대경의 다이스를 이용해 상기와 동일과정을 거쳐 상온에서 냉각시키도록 한 조립식 강관전주의 제조방법.Heat the expansion pipe part of steel pipe to 200˚C and apply drawing oil with a kinematic viscosity of 90 ° or more at 50˚ standard to relatively small diameter die first and advance it into the expansion pipe section, and then heat it to 300 ~ 450˚C on the surface of the steel pipe outside the approach. To retreat the die of the small diameter, and to cool at room temperature through the same process as above using a relatively large diameter die. 제3항에 있어서, 소경과 대경의 다이스의 어프로치는 확관부의 전진방향에 반대되는 지점에 확관부의 최대내경을 이루는 극점이 형성되게 한 조립식 강관전주의 제조방법.The method of manufacturing a prefabricated steel pipe pole according to claim 3, wherein the approach of the die of the small diameter and the large diameter is such that an pole forming the maximum inner diameter of the expansion pipe is formed at a point opposite to the advancing direction of the expansion pipe. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
