Problems solved by technology

[0004] The disadvantage of the existing installation process is that the installation of the main truss and the secondary truss takes a long time for the lifting equipment, thereby reducing the use efficiency of the equipment and making the installation efficiency of the steel truss low
In addition, during the installation of the existing secondary truss, manual support is used to adjust the verticality and then spot welding is used, which has the problem of inaccurate control. At the same time, there are temporary welding marks on the main truss during the installation of the secondary truss, and secondary grinding is required and painting, this construction method also has an impact on the physical properties of the main truss profile, reducing its local bearing capacity

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] The sheet truss composite structure is composed of parallel main trusses and secondary trusses welded between the main beams. The installation method of the sheet truss composite structure in this embodiment, the installation method uses a method such as figure 2 , image 3 , Figure 4 Temporary supports for the main truss shown and as Figure 5 , Image 6 The secondary truss temporary support device shown is realized.

[0039] Such as figure 1 Shown is a schematic diagram of the hoisting of the sheet truss composite structure. It can be seen from the figure that the main truss 1 has been fixed above the steel pipe column 10 through the main truss temporary support device, and the secondary truss 1' is being hoisted.

[0040] The installation method of the sheet truss composite structure in this embodiment includes the following ...

Abstract

The invention relates to a mounting method for a flake-like truss composite structure and belongs to the technical field of aloft steel structure mounting. The mounting method is achieved by means of a primary truss temporary supporting device and a secondary truss temporary supporting device. By adoption of the mounting method, in-place stability and speed adjustment of the in-place position of one single steel truss can be effectively achieved, in-place stability of the steel truss not connected with a transverse rod is improved, the occupied time of a hoisting machine is shortened, mounting work efficiency of the steel truss is improved, the mounting period of the steel truss is shortened, and the in-place precision of the steel truss is improved.

Description

technical field [0001] The invention relates to an installation method of a sheet-like truss composite structure, belonging to the technical field of high-altitude steel structure installation. Background technique [0002] In the architectural design of modern large-scale venues, various complex aerial steel structures are used more and more. While the shape is novel, the difficulty of installation is also increasing. [0003] The sheet truss composite structure is a mesh-shaped aerial steel structure composed of main trusses and secondary trusses welded. At present, the main truss adopts the traditional hoisting process. The sling of the hoisting equipment fixes the main truss on the truss support. By adjusting the position of the bottom of the truss, the positioning axis of the main truss coincides with the control line of the support. Spot weld the bottom of the truss to the support, then adjust the verticality of the truss, weld and fix the upper end of the truss to th...
