PIPE ROOF STRUCTURES

摘要

A steel pipe roof structure is provided to make construction possible without any additional horizontal support beam by connecting steel pipes horizontally and securing the horizontal stiffness. The invention relates to a steel pipe roof structure for enhancing horizontal stiffness by connecting many steel pipes(200) horizontally, wherein the steel pipe includes many supports installed on the inside of the steel pipe at regular intervals, horizontal grooves formed by cutting open one side of the steel pipe horizontally to support the load by earth pressure, and a pair of angles fixed to one side of the steel pipe correspondingly to the horizontal grooves.
