Large-span steel structure roof sliding method for electronic factory building

Abstract

A large-span steel structure roof sliding method for an electronic factory building is characterized by including the following steps: a. arranging a steel pipe column 351*10mm in diameter beside theinner side of a two-layer concrete column at each roof steel structure truss base on each side of the plant span; b, connecting the bottom of each steel pipe column with a two-layer lattice beam through a hoop; c, arranging a sliding track beam at the tops of the steel pipe columns; d, placing a 43kg track in the middle of the top of the track beam; e, placing a sliding shoe at a position corresponding to a steel beam of a bottom cord of a roof steel structure truss and above the 43kg track; f, providing a crawler, and pushing the sliding shoe by the crawler; g, completing the entire roof sliding mounting by a roof steel structure truss sliding process. The large-span steel structure roof sliding method has the advantages that a sliding process device is simple in structure, the sliding construction quality is safe and reliable, the problem that two-layer boards of plants cannot be mounted by crawler cranes and roof steel structure sliding cannot be carried out by original design structures are solved, the construction time is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a large-span steel structure roof of a factory building, in particular to a sliding method for the large-span steel structure roof of an electronic factory building. Background technique [0002] As a key facility for the production of chips, panels, etc., the electronic factory building is an indispensable production factory building for high-tech electronic product equipment. Due to the rapid replacement of electronic products and the high requirements for the production environment, the production plant has extremely high requirements for production speed and cleanliness, which makes construction difficult. [0003] At present, the second-floor plane structure of the main workshop of the electronic factory is generally in the form of waffle boards or lattice beams, the columns on the second floor have steel columns or concrete columns, and the roof is in the form of steel structure trusses. The installation of steel structur...

AI Technical Summary

Problems solved by technology

[0004] Considering the investment and progress of the owner and the general contractor, the structural design is very optimized. The original structure cannot meet the crane on the second floor platform or use the original structure to slide, and the temporary measures cannot damage the concrete structure.

[0005] Therefore, there are above-mentioned inconveniences and problems in the known steel structure roof using the original structure to slip.
