Super-long attachment construction method of tower crane

Abstract

The invention discloses a super-long attachment construction method of a tower crane, and relates to the technical field of super high-rise construction. According to the super-long attachment construction method of the tower crane, for the tower crane, basic parameters, related parameters and connection location parameters of an attachment bar and the tower crane during attachment positioning areobtained, the parameters of the attachment bar are optimized, an attachment point of a core tube during construction are determined by utilizing a wind load and attachment basic parameters, meanwhile, attachment operation platforms are separately arranged at the tower crane and an attachment surface operation point, assembly and disassembly and a structure of the operation platforms are optimized, construction of a concrete structure on the core tube is carried out, field splicing and connection of the attachment bar are carried out, construction of an outer frame steel structure is carried out, and arrangement and attachment conversion of a position of a core tube attachment point are performed simultaneously.

Description

technical field [0001] The invention discloses a construction method, relates to the technical field of tower crane construction, and in particular relates to a super-long attachment construction method of a tower crane. Background technique [0002] Super high-rise buildings generally refer to buildings with more than 40 floors and a height of more than 100 meters. China's "General Rules for Civil Building Design" GB50352-2005 stipulates that when the building height exceeds 100m, both residential and public buildings are super high-rise buildings. In the case of modern super high-rise structure design, special-shaped venues, sightseeing towers, etc., the distance between the tower crane body and the attachment point exceeds the conventional attachment point. During construction, the frame-core tube structure is often used. Formwork construction makes it difficult for the flat-arm tower crane to attach to the tower structure at a close distance. It is often necessary to se...

Problems solved by technology

In the case of modern super high-rise structure design, special-shaped venues, sightseeing towers, etc., the distance between the tower crane body and the attachment point exceeds the conventional attachment point. During construction, the frame-core tube structure is often used. Formwork construction makes it difficult for the flat-arm tower crane to attach to the tower structure at a close distance. It is often necessary to set the attachment surface on the core tube shear wall, which will easily lead to an excessively long attachment distance, easily cause waste of resources, and cause disadvantages to construction within the frame. impact, which is not conducive to the normal progress of construction
