Construction method of super high-rise building reinforced layer steel structure outrigger truss

Abstract

The invention provides a construction method of a super high-rise building reinforced layer steel structure outrigger truss, belonging to the technical field of construction engineering. The method comprises the steps of construction preparation, outrigger truss processing and pre-assembly, outrigger truss lower chord member installation, floor concrete pouring, outrigger truss upper chord installation, web member installation, wall column steel bar binding, wall column formwork erection, beam plate formwork erection and steel bar binding, beam plate column concrete pouring, stress monitoring and analysis, web member post-welding, finishing coat and fire-proof paint brushing. According to the construction method of the super high-rise building reinforced layer steel structure outrigger truss, the whole truss is decomposed into parts and components which can be hoisted by field lifting equipment by utilizing the connection relationship of all rod pieces of the outrigger truss, so that integral hoisting is changed into high altitude bulk, the difficulty that the outrigger truss needs to be lifted by a large crane is overcome, and the construction is better in flexibility and operability.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a steel structure outrigger truss of a reinforced layer of a super high-rise building. Background technique [0002] In recent years, in the design of super high-rise buildings, rigid jibs have been widely used to improve the thrust resistance of the frame core tube system, but generally the rigid jib structures are heavy and complex in technology, making construction difficult. Contents of the invention [0003] The technical task of the present invention is to solve the deficiencies of the prior art, and provide a construction method for the steel structure outrigger truss of the reinforcement layer of super high-rise buildings. [0004] Use software-assisted drawing technology to stake out the nodes of the outrigger truss, and divide the entire steel truss into units that can be directly hoisted by on-site hoisting machinery such as...
