Rapid construction method of arched pipe truss

Abstract

The invention discloses a rapid construction method of an arched pipe truss. The rapid construction method comprises the following steps that (1) a BIM structural model of the arched pipe truss is established; (2) horizontal integrated pre-assembly and segment welding are performed in a factory for the pipe truss to form truss bodies to be transport to a site; (3) the truss bodies are assembled to form two main trusses; (4) in-span brackets are installed; (5) the two main trusses are lifted and welded to connect the two main trusses into the pipe truss; (6) the assembled pipe truss is lifted in place to complete installation of the pipe truss; (7) the steps 2-6 are repeated to form two pipe trusses, a secondary truss and a roof support are installed, so that the installed part forms a whole force system; and (8) the steps 2-7 are repeated until all pipe trusses are installed. According to the rapid construction method of the arched pipe truss, in-span vertical one-time splicing rapid construction of the arched pipe truss can be completed in the case of poor on-site site conditions, the risks of working at height are reduced, the construction period is ensured, the construction cost is saved, and multiple purposes are achieved at one stroke.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a rapid construction method of an arched pipe truss. Background technique [0002] The space pipe truss structure is developed on the basis of reticulated shell and grid structure, usually with regular triangular, inverted triangular and quadrilateral cross-sections, among which inverted triangular cross-sections are mostly used, and its lateral stability and torsion resistance are relatively low compared to plane The pipe truss has been significantly improved, with better stability, larger internal space, novel and beautiful shape, less steel consumption, and more environmentally friendly. Therefore, the proportion of buildings is increasing, and it is widely used in large-span factory buildings in industrial buildings, as well as large public buildings such as theaters, gymnasiums, and exhibition halls in civil buildings. At present, there are many advanced techn...

Problems solved by technology

[0005] Aiming at the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problems in the prior art that the number of pipe trusses is large, the span of a single span is long, the weight of a single truss, the height of the arching is high, and the installation of the roof of the pipe truss structure on site is solved. There are problems such as long construction time, low construction efficiency, high requirements for equipment, and large safety hazards. A rapid construction method for arched pipe trusses is provided, which can complete the spanning of arched pipe trusses under the condition of poor site conditions. The rapid construction of one-time pairing not only reduces the risk of high-altitude operations, ensures construction safety and construction period, but also saves construction costs.
