Single-layer latticed shell steel structure roof and installation method thereof

Abstract

The invention discloses a single-layer latticed shell steel structure roof and an installation method thereof. The single-layer latticed shell steel structure roof comprises a roof grid, V-shaped supporting columns, tree-shaped supporting columns and side elevation horizontal supporting rods; the roof grid is formed by welding box type section structural steel rods; the V-shaped supporting columns, the tree-shaped supporting columns and the side elevation horizontal supporting rods are supporting structures of the roof grid and are connected to the curved surface grid in a hinged mode or a rigid connection mode; the lower parts of the V-shaped supporting columns are connected to bottom structures through H-shaped structural steel columns; the lower parts of the tree-shaped supporting columns are connected to the bottom structures through cross-shaped structural steel columns or sliding supports; the side elevation horizontal supporting rods comprise cantilever beams and two-force bars. According to the installation method, the sectional symmetric and synchronous construction method is adopted, and unloading is carried out according to the general principle of sectioning and synchronizing. The structure is reasonable, the method is orderly, and the overall installation accuracy and the stability are guaranteed.

Description

technical field [0001] The invention relates to the field of steel structure buildings, in particular to a single-layer reticulated shell steel structure roof and an installation method thereof. Background technique [0002] With the progress of society and the development of economy and science and technology, people's life pursuit and aesthetic concept are getting higher and higher, and some new-style building structures have emerged. In recent years, a large bird-shaped curved reticulated shell structure The long-span single-layer reticulated shell steel structure has gradually become a representative of many novel architectural shapes. [0003] The overall spatial shape of the big bird-shaped roof structure is complex, and the spatial position relationship is irregular. In addition, the roof grid is a single-layer grid structure, the cross-section of the rods is relatively small, the structural rigidity is also weak, and the structural span is large. The largest regiona...

Problems solved by technology

In addition, the roof grid is a single-layer grid structure, the cross-section of the rods is relatively small, the structural rigidity is also weak, and the structural span is large. The maximum regional structural span is more than 40 meters. During the construction and installation phase, it is difficult to control the installation deformation of the entire roof structure How to install the roof grid structure is a major difficulty in the project; compared with general building structures, this type of building has the characteristics of high height, large span, and high sensitivity to structural defects; To achieve positioning and installation, a large number of tire frames and large-tonnage lifting equipment are required. For this type of building, due to the large span of the roof, the spatial structure layout is relatively complicated. How to complete the installation of the large-span roof structure and ensure the overall Installation accuracy, and at the same time, the various structures do not interfere with each other during the construction process, and they are in order, which is bound to become a problem.
