Lateral reinforcing structure in whole lifting of plane steel truss and whole lifting method

Abstract

The invention relates to a lateral reinforcing structure in whole lifting of a plane steel truss and a whole lifting method. The lateral reinforcing structure comprises an upper chord member reinforcing device and a lower chord member reinforcing device, wherein the upper chord member reinforcing device and the lower chord member reinforcing device are connected to form a whole body through an inclined steel pipe; the upper chord member reinforcing device comprises two inner through beams, two outer through beams, two lower through beams, an upper large cross beam, a lower cross beam, an upper small cross beam and a stand column; and the lower chord member reinforcing device is formed by an upper limiting beam, a lower limiting beam and a lateral limiting stand pipe. The lateral reinforcing structure adopts a specific structure form, a lower anchor point is arranged on an upper chord member of the steel truss of a plane structure, and an auxiliary lifting bracket tool is arranged at the position of an upper anchor point, so that a construction method of the whole lifting of the existing steel truss is optimized, and the construction quality and the safety of the whole installation of a large-span steel truss are effectively guaranteed. The lateral reinforcing structure in the whole lifting of the plane steel truss and the whole lifting method can be widely applied to the lifting construction of various large-span steel structures.

Description

technical field [0001] The invention relates to a hoisting method of a large-span steel truss and a temporary reinforcement structure adopted during the hoisting process, in particular to a hoisting method which is assembled on the ground and hoisted as a whole to the installation position and the temporary reinforcement adopted during the hoisting process structure. Background technique [0002] Chinese traditional ancient architecture has a pivotal position in the history of world architecture with its simple and solemn appearance and smooth and changeable curves. In the field of traditional ancient buildings in our country, most of them are wood structures, brick-wood structures or masonry structures. In the emerging field of antique architecture, due to the shortage of timber resources and the limitations of traditional craftsmanship, traditional ancient architectural structures can no longer meet the special requirements of large spans and large cantilevers in modern ...
