Long-span steel truss-concrete composition roofing integral lifting method
The invention relates to lifting of building structures, and relates to a long-span steel truss-concrete composition roofing integral lifting method. The long-span steel truss-concrete composition roofing integral lifting method comprises that a long-span steel truss structure is assembled on the ground; after the steel truss is assembled, a concrete composite floor structure is constructed on the top of the steel truss, and steel bars are bound; in dependence on the concrete pouring area, the steel truss steel beam distribution characteristic and the shape and size of the structure, the concrete composition roofing is divided into blocks, the pouring of the concrete composition roofing is carried out symmetrically in the circumferential direction from interior to exterior; a hydraulic lifting system is provided with a pressure sensor and a stroke sensor, the pressure sensor feeds back to the pressure of a lifter, the stroke sensor feeds back to the stroke of a lifter, and a lifting structure is provided with a laser range finder used for displacement feedback; and during the lifting process, comparison is carried out in dependence on three monitoring conditions, if one parameter exceeds a set deviation, rectification is carried out. According to the invention, the integral long-span steel truss-concrete composition roofing are arranged in place, and during the lifting process, the concrete structure does not generate cracks.
