Embodiment 1

[0064] The main entrance of the administrative building of Kuwait International Airport adopts a curved space truss structure. see now figure 1 , figure 1 It is a schematic diagram of a curved space tube truss structure according to an embodiment of the present invention. As shown in the figure, the curved space tube truss structure includes a rectangular section A roof truss, a fan-shaped B-section roof truss and a fan-shaped front C-section roof truss, and is characterized in that:

[0065] The fan-shaped B-section roof truss is arranged in the middle of the curved space tube truss structure, the fan handle is connected to the rectangular A-section roof truss, and the fan front is connected to the fan-shaped front C-section roof truss.

[0066] Among them: the rectangular section A roof truss is composed of two cross-shaped trusses connected, the rectangular section A roof truss and the fan-shaped section B roof truss are supported by several columns 1, and the columns are...

Embodiment 2

[0068] The main entrance of the administrative building of Kuwait International Airport adopts a curved space truss structure. The roof trusses are composed of steel pipes with diameters of 193mm, 159mm, 121mm, and 60mm. The materials are all S275N. The heaviest weight of a single roof truss is 2.8 tons. The total length of the main entrance truss is 60m, the total width is 57m, and the total weight is about 137 tons.

[0069] The installation method of the curved surface space pipe truss structure of the present invention is to manufacture the truss members domestically, transport them by sea in containers, assemble them at overseas construction sites, and then hoist them. It is characterized in that it includes the following steps:

[0070] a. Preparatory work before construction

[0071] (1) Prepare site operating conditions

[0072] "Three connections and one leveling" at the construction site; the relevant foundation floor and other projects are basically completed, and ...

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...
