The invention relates to the technical field of floor
system and roof
system construction of large-span
architectural engineering, in particular to a large-span
pipe truss hoisting method. The large-span
pipe truss hoisting method comprises the following steps that step one, measurement and re-examination are carried out; step two, arc-shaped steel column segment and circumferential truss hoistingis carried out; step three,
temporary operation platform installation is carried out; step four, main truss
bed-jig
assembly is carried out; step five, main truss hoisting is carried out, and specifically, a
quincunx integral hoisting method is adopted in super-long plane main truss horizontal segment steel beam hoisting; and step six, end portion arc-shaped segment secondary truss and truss hoisting is carried out. A loading feature of higher rigidity of element itself in a plane is fully used, installation errors and accumulative errors generated during truss segment installation of the large-span prestress tool
orthogonal plane pipe truss
system can be effectively solved, construction technology of a
quincunx integral hoisting super-long tool
orthogonal plane pipe truss is adopted, andthe problems that the rigidity is higher but out-of-plane rigidity is relatively weak, and element overall deformation is nonuniform in the hoisting
processing of a plane truss are solved.
