Jacking supporting system and method for large-span steel structure

Abstract

The invention relates to a jacking supporting system and method for a large-span steel structure. The jacking supporting system comprises fixing seats, stand columns, telescopic devices, jacking beams and splicing structures, wherein the fixing seats are mounted on the construction ground and arranged at intervals; the stand columns are vertically arranged on the fixing seats; the telescopic devices are rotatably arranged on the fixing seats, and the heights of the telescopic devices are adjustable; the jacking beams are fixedly arranged on the telescopic devices; and the splicing structures are arranged on the stand columns and connected with the large-span steel structure in a supporting mode. The telescopic devices are rotated to drive the jacking beams to rotate, so that the jacking beams are located below the splicing structures; and the heights of the telescopic devices are adjusted to enable the jacking beams to jack the splicing structures upwards, and splicing units are additionally mounted between the splicing structures and the stand columns, so that the splicing structures are heightened, the splicing structures are heightened continuously until the large-span steel structure is jacked to the mounting position to complete mounting of the large-span steel structure, the potential safety hazards of manual aloft work for building the splicing structures are avoided, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a jacking support system and method for a large-span steel structure. Background technique [0002] With the development of the economy, the traditional structural forms are increasingly unable to meet the needs of novelty and creative expression. Long-span structures are favored by more architects and adopted by owners. [0003] In order to meet the installation requirements of space structures and long-span structures, different steel structure installation processes have been developed. At present, the installation process of space structures and large-span structures usually uses lifting equipment to hoist several unit steel structures to several assembled truss structures, support the unit steel structures through several unit truss structures, and then carry out the unit steel structure The assembly and installation are fixed, but the high-altitude assembly and installa...
