Abstract

The invention discloses a method for erecting a ground assembling jig frame of a spatially crossed large-span cantilever truss, and relates to the technical field of awning steel structures. The spatially crossed large-span cantilever truss ground assembling jig frame structure comprises a fixed base, a telescopic stand column, an operation platform support, a pipe fitting supporting frame, a cantilever beam, a transverse connecting piece and a longitudinal connecting piece, and the fixed base is composed of H-shaped steel, a clamping groove and a bolt. The model specification of the H-shaped steel is HM300*200. According to the method for erecting the ground assembling jig frame of the spatially crossed large-span cantilever truss, standardized assembling parts are prefabricated and installed, the structure is safe, stable and reliable, the assembling and disassembling efficiency is high, and cost reduction and speed increase are achieved.

Description

technical field [0001] The invention relates to the technical field of canopy steel structures, in particular to a method for erecting a space-intersecting large-span cantilever truss ground-assembled tire frame. Background technique [0002] The design dimensions of the steel structure of the canopy of the venue project are getting larger and larger, and the difficulty of assembling the plane and space truss on the ground is increasing. [0003] When erecting the steel structure plane and space truss ground assembly frame of the existing stadium project, the truss assembly frame is assembled by welding H-shaped steel and angle steel according to the external dimensions of the truss. , and then use H-shaped steel and angle steel welding to form a new assembled tire frame according to the external dimensions of another truss. This method of erecting a truss ground assembled tire frame has a large amount of welding, low erection efficiency, and difficult control of the vertica...
