Abstract

The invention discloses a platform layer for a transportation junction and a method for hoisting steel beams below the platform layer. The method comprises the following steps that S1, hoisting points are arranged on all the steel beams; s2, all the steel beams are transported to the site for orderly arrangement of all the construction positions; s3, a steel wire rope of hoisting equipment is connected with the hoisting point for hoisting; s4, measuring and correcting the steel beam; s5, the corrected steel beams are fixedly connected with the steel columns through high-strength bolts; s6, the steel beams are welded and fixed; s7, performing post-welding flaw detection on the steel beam; and S8, anti-corrosion coating construction is conducted on the steel beam. The device has the advantages of being high in safety, energy-saving, environment-friendly and capable of improving the hoisting quality and the hoisting efficiency.

Description

technical field [0001] The invention mainly relates to the construction technology of the Universiade urban comprehensive transportation hub, and in particular to a method for hoisting steel girders at the platform level and below of the transportation hub. Background technique [0002] Universiade Urban Comprehensive Transportation Hub is located at the intersection of Henggang Sub-district Office and Longcheng Sub-district Office, on the south side of the intersection of Longgang Avenue and Longfei Avenue, about 5 kilometers from Longgang Central City and 25 kilometers from Futian Central District. The current situation is the Universiade Station of the existing Line 3, and it is planned to transfer to Line 14 (Phase 4), Line 16 (Phase 4) and Line 33 (Zhongshenhui) at this station, forming 4 rail line transfers hub station. The Universiade Hub is modeled on the theme of "Dancing in the Bay Area", and the overall shape is elegant and light. The canopy adopts a space truss ...
