Installation method of special-shaped and curved-surface suspension type steel structure system

Abstract

The invention belongs to the technical field of steel structure construction, and particularly relates to an installation method of a special-shaped and curved-surface suspension type steel structuresystem. The problems are solved that the construction precision of a traditional installation method is difficult to guarantee, the construction period is long, a large amount of cost needs to be invested in scaffold and inclined suspender layer-by-layer hoisting, and many high-altitude hidden dangers exist. The special-shaped and curved-surface suspension type steel structure system comprises a core cylinder, a giant truss, a temporary support, an inclined suspender and beams of all floors. The installation method comprises the following steps that S1, the core cylinder is constructed; S2, the temporary support is installed; S3, the giant truss is assembled on the ground; S4, the giant truss is hoisted; S5, the inclined suspender is installed; S6, the temporary support is unloaded; S7, the beams of all the floors are hoisted; and S8, the displacement of the giant truss is monitored in the steps of S4-S7. According to the installation method, the construction precision is guaranteed, the installation efficiency is high, the installation construction period is shortened, and the operation safety risk is reduced. The erection and hoisting cost of a scaffold is saved, the high-altitude butting joints are reduced, the near-edge protection cost is reduced, and therefore the construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of steel structure construction, and in particular relates to an installation method of a special-shaped and curved surface suspended steel structure system. Background technique [0002] With the continuous development of science and technology and architectural design, people have higher and higher requirements for architectural shapes and functions. In order to meet these requirements, some new suspension steel structure systems with special shapes and curved surfaces have gradually entered people's field of vision. [0003] The traditional construction scheme is: [0004] Plan 1: The structure is formally installed, the suspenders and floor beams are hoisted in layers and sections from bottom to top, and finally the giant trusses on the top are assembled in the air; the giant trusses are assembled in the air, and a large number of aerial butt welding will easily cause more welding defects. Construction ...
