Problems solved by technology

[0006] The present invention aims to solve the deficiencies in the prior art, so a rapid installation method for high-rise steel structure truss roofs is proposed to solve the problem that large-scale hoisting machinery or multiple hoisting machinery cannot be used due to safety, economy, site or other construction reasons. The overall installation and construction of roof steel trusses effectively solves the difficult problems of high-rise roof steel truss hoisting and long overall construction period

Abstract

The invention discloses a rapid installation method of a high-rise steel structure truss roof, and belongs to the technical field of high-altitude steel structure installation. A tubular steel truss structure of the high-rise steel structure truss roof is completely formed by splicing and welding steel rod pieces and joints on a ground temporary supporting frame, a steel rail is installed on a constructed concrete roof truss beam, through a double-machine-platform crane, field hoisting requirement is met, then a steel truss is hoisted to a preset elevation position, alignment is carried out, then the steel truss slides to a designed position in parallel through a traction device, and finally is assembled, welded and filled in the air at high altitude through a tower crane, and the overallinstallation of the roof steel truss is completed. According to the rapid installation method of the high-rise steel structure truss roof, installation is adapted to local conditions, overall layout can be carried out by combining on-site temporary building facilities, a large steel truss assembling and hardening site is not needed, the assembling and welding time of the whole truss is saved, manpower resources are reasonably organized, beat line production construction is adopted, the construction difficulty and safety risks generated by overall hoisting of the roof steel truss are greatly reduced, the construction period is shortened, and the construction safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of steel structure construction, and in particular relates to a quick installation method for a high-rise steel structure truss roof. Background technique [0002] In the current steel structure design and construction, various complex aerial steel structures are being used more and more. The unique and novel shapes give people a refreshing visual impact and leave a deep impression on us. The focus of the steel structure is the support system. Of course, there are many types of steel structure support systems, such as: net frame, steel frame, steel truss and so on. Let's take a look at the steel structure support system-truss. The so-called truss refers to a lattice structure composed of straight rods connected to each other at the ends of the rods, mainly for bending resistance, while most of the rods required for roof steel trusses are processed and manufactured in factories, and finally shipped to the co...
