Problems solved by technology

[0002] The high-altitude and long-span multi-layer steel structure in the prior art is generally assembled on site and then directly hoisted by a crane. This method has the following disadvantages. The site needs a relatively large installation site to complete the installation
On the other hand, the crane used also needs to occupy a huge space
So this construction method is not suitable for use around some public facilities in use

Embodiment 1

[0013] As shown in the figure, the construction method of the long-span steel structure corridor described in this embodiment, such as figure 1 As shown, the supporting steel columns 1 on both sides of the span are installed first, and the auxiliary truss 2 is installed between the two supporting steel columns 1 . Then if figure 2 As shown, the horizontal horizontal steel beam 3 is hoisted with the auxiliary truss 2 as the lifting point 7, and then the supporting steel beam 8 and the diagonal steel beam 4 between the upper and lower horizontal horizontal steel beams 3 are installed. Then as image 3 As shown, the auxiliary truss 2 is removed, and then the vertical horizontal steel beam between the two horizontal steel beams 3 and the horizontal tie rods are installed, and finally the horizontal steel beam 6 required for construction is installed.

[0014] On the other hand, the elastic deformation of the high-altitude steel beam due to its own weight is obtained through cal...

Abstract

The invention provides a long-span steel structure corridor construction method. Support steel columns on two sides of a span are firstly installed, then transverse horizontal steel beams are hoisted, support steel beams and oblique support steel beams among the transverse horizontal steel beams are installed, a vertical horizontal steel beam and a striding horizontal draw rod are further installed between two transverse horizontal steel beams, and finally transverse steel beams required by construction are installed. The long-span steel structure corridor construction method is characterized in that auxiliary trusses are installed between the support steel beams after the support steel beams are installed, and the auxiliary trusses serve as hanging points to hoist the transverse horizontal steel beams and then dismantled after the support steel beams and the oblique support steel beams are further installed between the transverse horizontal steel beams. The long-span steel structure corridor construction method has the advantages of utilizing the auxiliary trusses to install the transverse horizontal steel beams with largest volume, adopting a spare part hoisting mode for an overall steel structure and reducing the field requirement of surrounding construction and the requirement for a crane.

Description

technical field [0001] The invention relates to a steel structure construction method, in particular to a long-span steel structure corridor construction method. Background technique [0002] The high-altitude and large-span multi-layer steel structure in the prior art is generally assembled on site and then directly hoisted by a crane. This method has the following disadvantages. The site needs a relatively large installation site to complete the installation. On the other hand, the crane used also needs to take up a huge space. Therefore, this construction method is not suitable for use around some public facilities in use. Contents of the invention [0003] The object of the present invention is to provide a construction method for a long-span steel structure corridor that is convenient for construction, occupies less construction site, uses a small crane, and has a firm structure after installation. [0004] In order to achieve the above purpose, the construction met...
