Upper chord bracing for high-altitude assembly of pipe truss and construction method of upper chord bracing

Abstract

The invention discloses an upper chord bracing for high-altitude assembly of a pipe truss and a construction method of the upper chord bracing. The upper chord bracing comprises a stand column bracing body, the stand column bracing body is formed by assembling a lower stand column bracing part and an upper stand column bracing part, and the assembling face is an inclined face; the upper stand column bracing part comprises an upper stand column and an upper stand column upper supporting plate arranged on the top face of the upper stand column, the upper stand column upper supporting plate is provided with a U-shaped clamping groove part used for fixing the pipe truss, the U-shaped clamping groove part is composed of a first T-shaped structural plate and a second T-shaped structural plate, the first T-shaped structural plate and the second T-shaped structural plate each comprise a vertical plate and a vertical plate supporting plate, and the pipe truss is fixed between the vertical plates of the two T-shaped structural plates; and the vertical plate supporting plates are connected with the upper stand column upper supporting plate through bolts, strip-shaped holes are formed in the upper stand column upper supporting plate, the bolts can pass through the strip-shaped holes, the vertical plate distance between the two T-shaped structural plates can be adjusted according to the diameter of the pipe truss, and the forming direction of the strip-shaped holes is the moving direction of the two T-shaped structural plates. The upper chord bracing simplifies the operation process and can guarantee the assembly precision.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a high-altitude assembled upper chord support of a pipe truss and a construction method thereof. Background technique [0002] The large-span three-dimensional steel pipe truss structure of the roof of various venues usually adopts the construction method of high-altitude loose assembly due to the characteristics of high building density, small spacing between building units, and no large assembly site around the venue. During the sliding process of the steel pipe truss that adopts the high-altitude loose construction method, there is a conflict between the chord and the upper chord support vertical rod route, and the upper chord support requires frequent overall installation and disassembly, and the process is complicated. During the removal process of the upper chord support, the steel pipe truss needs to be lifted and unloaded as a whole, which is likely to cau...
