Abstract

The invention relates to a steel structure hoisting slide support seat with large span and a construction process thereof. The steel structure hoisting slide support seat with large span comprises a support boss surface steel plate platform, wherein the support boss surface steel plate platform is welded and fixed with a lower pre-embedded steel column angle groove by a high-strength bolt; a slide steel plate base is arranged on the support boss surface steel plate platform and connected and fixed with the support boss surface steel plate platform through steel columns; a gap between the support boss surface steel plate platform and the slide steel plate base is filled by high-strength grouting materials; an upper slide steel plate is arranged on the slide steel plate base; the top of theupper slide steel plate is provided with a polytetrafluoroethylene plate; the top of the polytetrafluoroethylene plate is provided with a reinforcing steel plate, and one side of the reinforcing steel plate is provided with a slide steel plate. The invention has reasonable design, safety, reliability and high construction speed and successfully solves the problem of hoisting of a steel truss structure with large span under the condition of unstable deviation of a support boss.

Description

technical field [0001] The invention relates to a large-span steel structure hoisting sliding support and its construction technology. Background technique [0002] The safe hoisting of large-span steel structures is based on the stable cap, through the steel column feet embedded in the cap, hoisting and welding the long steel columns section by section, and then hoisting the steel truss beam on the top of the stable steel column. If the corner of the foundation steel column has a certain deviation, the foundation or column foot must be corrected first. After the foundation is stable, the steel column will be hoisted section by section according to the normal installation method. After the hoisting of the steel column is completed, the upper steel truss will be hoisted. Contents of the invention [0003] The purpose of the present invention is to provide a large-span steel structure hoisting sliding support and its construction technology, to solve the problem of steel col...
