Curved surface space pipe truss structure and mounting method thereof

Abstract

The invention relates to a curved surface space pipe truss structure. The curved surface space pipe truss structure comprises a rectangular A section roofing truss frame, a sector shape B section roofing truss frame and a sector shape front C section roofing truss frame and is characterized in that the sector shape B section roofing truss frame is arranged at the middle of the curved surface space pipe truss structure, and a sector handle part of the sector shape B section roofing truss frame is connected with the rectangular A section roofing truss frame; a sector front part of the sector shape B section roofing truss frame is connected with the sector shape front C section roofing truss frame, wherein the rectangular A section roofing truss frame is formed by connecting two crossed truss frames, and the rectangular A section roofing truss frame and the sector shape B section roofing truss frame are supported by a plurality of standing columns (1) which are perpendicular to the ground, and the level elevation of the top of the A section roofing truss frame and the top of the B section roofing truss frame is greater than or equal to 15m; the sector front part is connected with the sector shape front C section roofing truss frame and is supported by the jointed supporting of the standing columns (1) and oblique columns (7). According to the curved surface space pipe truss structure and the mounting method thereof, methods of assembling roof truss frames on the ground and whole-section hoisting are adopted, and the curved surface space pipe truss structure has the advantages of being succinct and convenient to construct, and short in construction period, the construction quality is easy to guarantee, the amount of large-scale mechanical equipment is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a truss structure, in particular to a curved space tube truss structure and an installation method thereof. Background technique [0002] In recent years, the space truss system structure has developed rapidly due to its light weight, large span, short construction period, complex shape changes and beautiful revetments, and has been widely used in large-space public buildings such as gymnasiums, exhibition tubes, and airports. [0003] The main entrance of the administrative building of Kuwait International Airport, an overseas project, adopts a curved space truss structure. The fan-shaped truss structure is composed of outer inclined columns, columns and roof trusses. The heaviest single roof truss is 2.8 tons, and the total length of the main entrance truss is 60m. The total width is 57m and the total weight is about 137 tons. The truss steel structure of the main entrance is manufactured in China. After the pre-assembled in...

AI Technical Summary

Problems solved by technology

[0004] Since Kuwait is located in the Middle East, the roof truss adopts the known installation method of fixed supports at both ends, which will cause stress due to the large temperature difference between day and night in the Middle East, resulting in deformation and failure of the truss structure. Before installation, the stability of the inclined column is also a construction difficulty

[0005] Therefore exist above-mentioned inconvenience and problem in known roof truss installation
