Problems solved by technology

[0004] First, the first roof girder and the second roof girder can only be temporarily fixed, and additional investment in cable wind ropes and chains is required
[0005] Second, the first roof beam and the second roof beam fail to form a whole with spatial rigidity and stability, and it is difficult to control the stability at high altitude, which increases its safety risk factor
[0006] Third, the installation of the tie rods and purlins is carried out at high altitude, and the operators are in a dangerous environment. The work efficiency is low, the installation speed is slow, and the construction period is affected.

Abstract

The invention provides a method for installing steel structure roof beams. The method includes the steps of respectively assembling two single-frame roof beams, fixing the two single-frame roof beams on a steel platform, installing tie bars and a purline on the steel platform, selecting steel wire ropes and a crane, connecting the crane with the two single-frame roof beams through the steel wire ropes, carrying out initial hoisting, after the initial hoisting is qualified, hoisting the two single-frame roof beams to the tops of steel columns, fixing the two single-frame roof beams to the tops of the steel columns, and sequentially repeating the hoisting process to complete hoisting of all the roof beams. According to the method for installing the steel structure roof beams, the tie bars and the purlines are installed on the bottom face, and the safety is high; every two single-frame roof beams are hoisted at a time, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to a roof beam installation method, in particular to a steel structure roof beam installation method. Background technique [0002] In the current traditional steel structure roof beam installation method, when installing the first roof beam, the hook cannot be loosened and aligned with the center line of the roof beam support or the positioning axis. The components are pulled firmly on both sides, and the crane can only remove the hook and leave after it is fixed securely. After the second roof girder is hoisted in the same way and put in place, make a preliminary correction before releasing the hook, fix it with the first roof girder with tie rods, then install the support system and some purlins, and finally adjust and fix it, starting from the third roof girder Beams are installed sequentially. [0003] This roof beam installation method has the following limitations: [0004] First, the first roof girder and the second roo...
