Steel truss assembly system and construction method

Abstract

The invention relates to a steel truss assembly system which comprises a steel truss, a ground, a structural column, an installation point, an aerial assembly device and a hoisting system. The structural column is arranged on the ground, the installation point is arranged at the top end of the structural column, and the two ends of the steel truss are arranged at the installation point; the hoisting system comprises a hoisting point support frame, a steel rope, a hoisting hook and a crane, wherein the hoisting point support frame is arranged on the steel truss, the hoisting point support frameis connected with the steel rope, the crane is arranged in a ground operation area, and the crane is connected with the steel rope through the hoisting hook; and the aerial assembly device is arranged below a steel truss sectional splicing position. The steel truss assembly system has the beneficial effects that a track type adjustable vertical rod is adopted to support an assembly jig, the widthand the height of the assembly jig can be accurately adjusted, the system is suitable for assembling steel trusses with different forms and sizes, the installation precision of the steel trusses is improved, the engineering quality is improved, the construction progress is accelerated, construction is easy and convenient, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the field of steel trusses, in particular to a steel truss assembly system and a construction method. Background technique [0002] At present, my country's steel truss construction technology is developing rapidly. The components or parts are usually connected by welds, bolts or rivets, and then carried out by segmented and block hoisting, overall lifting, overall jacking, lifting and unfolding and other methods. Due to its light weight and easy construction, steel trusses are widely used in super high-rise buildings and large-span space structures, such as various gymnasiums, exhibition centers and some industrial plants. Modern steel structures are developing toward large-span, but during the hoisting and installation process, it is easy to find that the truss main chord is assembled in sections, welded, and it is difficult to correct the working height. It is difficult to control the camber, side flatness, elevation, and ce...

Problems solved by technology

Modern steel structures are developing toward large-span, but during the hoisting and installation process, it is easy to find that the truss main chord is assembled in sections, welded, and it is difficult to correct the working height. It is difficult to control the camber, side flatness, elevation, and center errors of the truss. It is difficult to control the position errors between the main trusses and between the trusses and other axes
