Embodiment 1

[0064] The construction process of the tool-type steel lattice column hoisting frame for high-altitude overall hoisting and large-span integrally assembled welded ball net frame includes the following steps:

[0065] (1) Grid construction

[0066] 1 grid welding:

[0067] All welding materials must have factory certificates. Before use, it should be baked in accordance with the provisions of the quality certificate and placed in an incubator. Welders can only work after passing the examination and obtaining a qualification certificate. The butt joint of the upper and lower chords and the welding of grid rods and welding balls are the key points of engineering welding. It must be cleaned up before welding, assembled, corrected and re-inspected, reserved for welding receipts, positioning welding, protection before welding, cleaning before welding, welding Pre-heating, welding, post-welding treatment and non-destructive testing are strictly controlled to ensure that the weldin...

Abstract

The invention discloses a construction process of a tool type steel lattice column lifting frame for high-altitude integral lifting large-span integral assembling welding ball net frame. The construction process comprises the following steps of (1) net frame construction; and (2) integral lifting of a pulling rod of the net frame. The process has the advantages of being convenient to operate, highin construction speed, excellent in quality, capable of saving labor and the like, the requirements for energy conservation and environmental protection are met, and no safety and quality problems occur in the construction process. According to the construction method, a traditional net frame lifting construction method is technically innovated, an advanced construction method is provided for building construction, and good social benefits are achieved.

Description

technical field [0001] The invention relates to a construction technique of a tool-type steel lattice column hoisting frame for high-altitude overall hoisting and large-span integrally assembled and welded ball net trusses, and belongs to the technical field of building construction. Background technique [0002] With the continuous development of the construction market, the quality standards of construction projects are getting higher and higher. Steel structure grid projects include the top layer of the main structure, and projects using steel structure grids are also more and more widely used. Large-span grid structures rely on The advantages of simple stress, high rigidity, light weight, saving steel and good overall stability have been widely used in various fields of the construction industry. The traditional method of assembling the grid at high altitude is to use scaffolding to set up the grid construction platform to the grid elevation, and then install the grid on...
