[0002] In modern construction, especially in the construction of high-rise buildings and large public facilities, circular inclined columns are often involved in hoisting and installation. Temporary reinforcement is required during the construction of circular inclined columns of steel structures. The stability and safety of the inclined column docking are very important. It is required to use a temporary connection and stable and reliable temporary reinforcement method before tightening the high-strength bolts after the inclined columns are docked. The traditional method is usually to weld two channel steels on the back of the inclined column as fixed points before the steel structure of the inclined column is hoisted to provide support during docking. There is a certain deviation in the angle of the welding point, and the early welding and later cutting have great damage to the original material. In addition, its fixing method is time-consuming and not conducive to rapid installation and dismantling. Utility Model Content
