[0002] Steel structure installation is an important part of steel structure engineering construction. With the development of my country's steel structure and the continuous updating of architectural concepts, the structural forms are becoming more and more diverse and complex. The steel structure designer and the steel structure itself contain The combination of technical aesthetics components and mechanical laws realizes the unity of force and shape. The visual space form presented by the steel structure reflects architectural creativity and realizes the unity of shape and meaning. It brings new challenges to the construction unit, especially for large-span and complex structures. The installation of steel structure is difficult during construction, the construction period is long, and the amount of high-altitude operations is large, which poses potential safety hazards

The invention relates to an installation and construction method of a large span steel structure. The installation and construction method comprises the steps that simplified units are mounted throughcombination of integral hoisting and hoisting in bulk, and the simplified units are assembled on the ground first; the simplified units and second main supporting steel beams are correspondingly hoisted, first main supporting steel beams in the simplified units are connected with reinforced concrete brackets first, and then the second main supporting steel beams are connected with four-head joints and the reinforced concrete brackets; any group of first secondary supporting steel beams and second secondary supporting steel beams is hoisted and installed, after completion, next group of firstsecondary supporting steel beams and second secondary supporting steel beams is hoisted and installed until five group of first secondary supporting steel beams and second secondary supporting steel beams are fully hoisted and installed; and a group of angular supporting steel beams, first oblique steel beams and second oblique beams is hoisted and installed, and after completion, next group of angular supporting steel beams, first oblique steel beams and second oblique beams is hoisted and installed until five groups of angular supporting steel beams, first oblique steel beams and second oblique beams are fully hoisted and installed. According to the installation and construction method of the large span steel structure, the construction progress can be speeded up, the operation efficiency is improved, and the hoisting machinery tonnage is reduced.
