Abstract

The invention discloses a large-span pipe truss roof truss assembling construction method. The method includes the steps that a first roof truss is assembled on an assembling platform and welded; a temporary supporting plane is placed on the first roof truss, and a second roof truss is assembled on the temporary supporting plane and welded; the second roof truss and the first roof truss are erected in sequence to be assembled and are supported and fixed through connecting rods; a platform stretching across the two roof trusses is arranged on the vertical faces of the first roof truss and the second roof truss, and a safety wind rope is arranged on the platform; and the upper chords and the lower chords of the first roof truss and the second roof truss are fixed. When a steel pipe truss isassembled, a special jig frame is not adopted, and the assembling platform erected on the ground is used, so that a large amount of measure materials are saved; and the two vertical faces are horizontally spliced, so that the consistency of the boundary dimensions and joints of the two vertical faces of the pipe truss roof truss can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a large-span pipe truss roof truss assembly method. Background technique [0002] In recent years, due to the advancement of science and technology and the wide application of new materials and technologies, many large-scale public buildings and industrial plants in my country have adopted steel pipe rods with rich shapes, light structures, simple force transmission, high rigidity, light weight, and single rods. Cross-tube truss structure. In long-span buildings, due to their huge size, it is difficult to assemble trusses. [0003] At present, domestic assembly methods mainly include: high-altitude loose assembly method; ground loose assembly method; high-altitude segmental assembly method; ground segmental assembly method; lifting rack assembly method. However, these assembly methods require the use of large-scale lifting equipment and special moulds, which have h...
