Steel-structure truss high-altitude arc sliding installing method

Abstract

The present invention relates to a high-level arc-line slide-moving installation method of steel structure truss. In the concrete, on the concentric curved steel beams respectivley positioned on two ends of the truss to be installed the sipways are respectively set, each of two ends of the truss is equipped with slipper respectively. A hydraulic traction equipment can be used for pulling the slipper and making it be moved along the slipway from far end place of two slipways. After the first main truss is hoisted to high level and assembled into one whole body, the slipper can be forwards slide-moved by one truss width, then the second main truss can be assembled and connected with member between trusses, and can be slide-moved by one truss width, so that the above-mentioned steps can be circulated until several truss units are assembled into a whole body unit, then the whole body unit can be slide-moved into the designed plane position.

Description

technical field

[0001] The invention belongs to the technical field of steel structure building construction, and in particular relates to a high-altitude arc sliding installation method of a steel structure truss. Background technique

[0002] With the vigorous development of my country's economic construction, large public buildings such as airports, convention centers, gymnasiums, auditoriums, etc. have been widely used. These buildings are generally long-span space steel structures, and the structural forms include grid frames and space trusses. The on-site installation of steel structures can generally be divided into high-altitude bulk method, strip or block installation method, high-altitude sliding method, Overall hoisting method, overall lifting method and overall jacking method. The pros and cons of on-site installation methods have a great impact on the construction period and overall cost. Each installation method has its own advantages and disadvantages. The...
