Problems solved by technology

[0003] However, it is difficult to control the hoisting quality of the roof beams of long-span light-weight steel factory buildings. The roof beams are easily deformed during the turning process, and the high-altitude stability is difficult to control during the hoisting process, and it is easy to cause waste of human and material resources.
[0004] Therefore there is above-mentioned inconvenience and problem in known large-span light steel structure roof girder hoisting method

Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0026] Embodiment of the present invention: the hoisting method of the large-span light-duty steel structure roof beam of the present invention is applied to the hoisting of the 55-meter long-span light-duty steel structure roof beam. Since the length of the 55-meter-span roof beam is super long, it can be processed in the factory, but Its transportation is difficult and uneconomical, so the 55-meter-span roof beams are manufactured and processed in sections, and then spliced ​​and hoisted after transported to the construction site. When the large-span light-weight steel structure roof trusses are transported into the site, they should be properly placed to avoid deformation, and the splicing site should be leveled with sleepers, and the relative elevation of the sleepers should be measured with a level. deformed, figure 1 It is a schematic diagram of assemb...

Abstract

The invention relates to a large-span light steel structure roof girder hoisting method which is characterized by comprising the following steps of: splicing and assembling to form an integral hoisting roof girder on ground in a hoisting site, selecting a hoisting steel wire rope, selecting a hoisting truck and a hoisting sling, executing initial hoisting and executing final hoisting. After the technical scheme is adopted, the invention has the advantage of high quality and is safe and quick to carry out hoisting construction.

Description

technical field [0001] The invention relates to a method for hoisting a steel structure roof beam, in particular to a method for hoisting a large-span light steel structure roof beam. Background technique [0002] The large-span light-weight steel structure factory building is assembled with light-weight high-efficiency steel and light-weight, high-efficiency heat-insulating enclosure materials, which can provide a large-span and large-space production area. It has light weight, short construction period, convenient installation, good seismic performance, and a Beautiful, clean, fast-paced, large internal space, and easier to separate spaces than ordinary structures, so it is widely used in general industrial and agricultural buildings, commercial, service buildings, standard office buildings, schools, hospital buildings, villas, tourist buildings , All kinds of warehouse buildings, entertainment, stadiums, buildings in earthquake zones, buildings with tight construction sch...
