specific Embodiment approach

[0017] Figure 1-Figure 5 It is a specific embodiment of the present invention. The specific implementation is as follows:

[0018] The first step is to process the temporary support tire frame 1, the height of the temporary support tire frame 1 is consistent with the elevation of the bottom of the frame;

[0019] The second step is to install the temporary support frame 1 at the middle position between the first frame column 2 and the second frame column 3;

[0020] The third step is to install the first section frame 4, so that one end of the first section frame 4 is placed on the temporary support tire frame 1;

[0021] The fourth step is to install the second frame 5, so that one end of the second frame 5 rests on the temporary support frame 1, and docks with the ends of the first frame 4;

[0022] The fifth step is to weld and fix the ends of the first section frame 4 and the second section frame 5, and then remove the temporary support tire frame 1, and the long-span ...

Abstract

The invention discloses a method for assembling a large-span steel frame by utilizing a temporary supporting bed jig, and belongs to the technical field of steel structure frame assembly. The temporary bed jig is arranged on the middle position of the large-span steel frame; the height of the temporary bed jig is the same as the bottom elevation of the frame; the frame is manufactured into two sections in a machining factory and the two sections are conveyed to the site for assembly; then the two sections of the frame are assembled by utilizing a crane; then the two sections of the frame are welded and fixed on the temporary supporting bed jig; then the temporary supporting bed jig is disassembled; and the large-span steel frame is assembled. The method has the advantages that the method is simple and easy to operate; midair single part assembly of frame supporting rod components is avoided, so that safety hazard is greatly lowered; meanwhile, assembly time is saved; labor and materials are saved; and construction cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of steel structure frame installation, and in particular provides a method for installing a large-span steel frame by using a temporary support frame. Background technique [0002] When installing the steel structure frame of the factory building, for the installation of the long-span frame, due to the difficulty of overall hoisting, it is generally adopted to install the upper and lower main beams of the frame first, and then install the supporting rods between the main beams. There are many supporting rods, and all need to be in the air The operation increases the difficulty of installation and poses a greater safety hazard. Invention content: [0003] The purpose of the present invention is to provide a method for installing a large-span steel frame by temporarily supporting the tire frame, and using the temporary support tire frame to install the large-span steel frame in two sections, avoiding the sin...
