Embodiment 1

[0060] The second phase of Jindu Han Palace is located at No. 66 Linjiang Avenue, Wuhan, with a 32-story frame shear wall structure. It started construction on December 15, 2006. The total construction area is 62112.14 square meters, the basement construction area is 7871.96 square meters, and the top floor is a large-span exhibition hall. The roof truss structure above the exhibition hall is a large-span and high-section steel pipe truss structure, with a total of 12 brackets, 10 main trusses, 68 secondary trusses, a large number of horizontal supports and purlins, with a total weight of 2700t. Among them, the span of the bracket is 36m, the span of the main truss is 60m, and the span of the secondary truss is 12m, which are evenly arranged along the length direction of the main truss at a distance of 6m. The main truss is undulating, with a height of 4-9m. It is in the shape of a two-way broken line, with a large diameter, complex nodes, and multiple intersecting steel pipes....

Embodiment 2

[0063] Three Gold One Hong Kong Image Project, the project is located in West Gutian Road, Wuhan City, 18-story frame shear wall structure, the third floor is the steel structure truss of the transfer floor, four reinforced concrete cylinders at the four corners are used as giant frame columns, and the steel structure truss The largest size is 16.2mX5.6m (length X height), the heaviest up to 22.3 tons. Also adopt the method described in embodiment 1 to install, ensure the quality and safety of construction, and this construction method saves construction measures cost about 150,000 in total, and the total construction period is advanced 30 days.

Embodiment 3

[0065] The aerospace capital residential building project is located in Dongfang Development Zone, Xiaogan City, Hubei Province. Construction started on November 8, 2008. The total construction area is 19,029 square meters, the basement area is 1,450 square meters, the 18-story frame shear wall structure, and the three-story transfer floor hall is a steel structure truss structure. The high-altitude and large-span steel structure segmented push-slide assembly method adopted in this project ensures the quality and safety of the construction, and this construction method saves a total of about 200,000 construction measures and the total construction period is advanced by 60 days.

Abstract

The invention relates to a segmental slipping and assembling process of an overhead large-span steel structure, which is characterized by comprising the following steps of: firstly building a temporary track beam support, then arranging a slipping track beam and an assembling jig frame on the temporary track beam support, assembling a steel structure truss element on the jig frame according to drawing requirements, dismantling the assembling jig frame after the assembly is finished, pushing and slipping the steel structure truss element forwards along the a slipping track, moving the steel structure truss element to the expected position of the steel structure, then carrying out next span area steel structure truss element assembly on the emptied-out assembling jig frame, carrying out welding connection between the next span steel structure truss element and the previous element, slipping and pushing the steel structure truss elements to the expected position in sequence, analogizing the process in sequence till all steel structure slipping and assembly are finished, and finally unloading, landing and fixing to finish the whole installation work of the steel structure.

Description

technical field [0001] The invention relates to a steel structure assembling process in the field of construction, in particular to a process suitable for basements or other structures in the construction site, which cause lifting machinery to be unable to enter the construction area or use other construction methods that are not economical and affect the construction period. The high-altitude long-span steel structure segmental sliding assembly process of the relatively large long-span steel structure. Background technique [0002] With the rapid development of my country's economy, China's steel output has increased rapidly in recent years, which provides favorable conditions for the development of my country's construction steel structure. In addition, the national policy encourages the use of steel and vigorously develops steel structure buildings. A large number of steel structure high-rise office buildings, long-span venues and public buildings have emerged, such as: B...
