Installation method of overlength mast with large inclination angle of space structure

Abstract

The invention relates to an installation method of an overlength mast with a large inclination angle of a space structure, which belongs to the technical field of architectural engineering construction. The installation method comprises the following steps: mast shaping and manufacturing in subsections, field splicing, anchor point and base arranging, integral hoisting, cable rope arranging, mast inclination implementing, process monitoring, cable rope checking, fastening, and installing the overlength mast with the large inclination angle with the length being more than 40m and the inclination angle being 65 degrees on the space structure. According to the method, floor subsection splicing and integral hoisting in situ are adopted, and a cable rope is released slowly through a chain block to control the angle of the mast, so that the mast in the space structure is inclined slowly so as to be positioned accurately; the requirement of the installation accuracy of a space structure system is met; the problems of how to control the dimensional accuracy of the mast, and large deviation of the spatial position, angle and relative position of mast installation in the space structure are solved; and meanwhile, the stability and the safety of a structure stress system are ensured, the installation quality of the mast is improved, and the risk of installation construction of the overlength mast with the large inclination angle is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a method for installing a space-structured mast with a super-long inclination angle. Background technique [0002] In the construction of space structure, in order to make the whole building stronger and more stable, technicians will set up masts around the building. The ground bearing platform is used to fix the mast. Generally, the mast is inclined to form a certain angle with the building to enhance its pulling effect; Certain difficulty. At present, the overall installation and construction of a mast with a super long inclination angle is a project with great construction safety risks. The special form of the structure determines that the structure does not have self-stability during construction and installation, that is, it is a "component" with a high risk of overall collapse. "The traditional installation method of joint lifting and sp...

[0002] In the construction of space structure, in order to make the whole building stronger and more stable, technicians will set up masts around the building. The ground bearing platform is used to fix the mast. Generally, the mast is inclined to form a certain angle with the building to enhance its pulling effect; Certain difficulty. At present, the overall installation and construction of a mast with a super long inclination angle is a project with great construction safety risks. The special form of the structure determines that the structure does not have self-stability during construction and installation, that is, it is a "component" with a high risk of overall collapse. "The traditional installation method of multiple cranes combined lifting and splicing has high risks. It is a difficult task to ensure the stability of the force system during installation, the safety of construction and the construction quality of the structure.
