Problems solved by technology

However, this traditional method consumes a long time and requires a lot of labor. The cross-sectional geometry, verticality, bending height, camber, and welding quality of the joints of the components are more difficult to control than those assembled on the ground.

Abstract

The invention discloses a large-span steel truss structure and an installation method thereof. The large-span steel truss structure comprises one group of steel frames and secondary trusses which are located between the adjacent steel frames and are vertically connected with the steel frames; each steel frame adopts a double-truss combined truss and comprises two supporting columns and a main truss located at the tops of the supporting columns; column pins are arranged at the lower parts of the supporting columns; each supporting column comprises one group of steel columns and reinforcing ribs which are alternatively distributed between the steel columns; each main truss comprises one group of upper chord plates, one group of lower chord plates and webs located between the upper chord plates and the lower chord plates. According to the installation method provided by the invention, a long slippage rail is paved at the lower part and a lot of labor force is alleviated; the whole structure can be divided into different construction regions according to different structures so that the construction is more convenient and rapid.

Description

technical field [0001] The invention relates to the field of steel structure buildings, in particular to a large-span steel truss structure and an installation method thereof. Background technique [0002] Large-span steel trusses have become a fast-growing structure type because of their reasonable force, full use of material strength, less consumables, light weight, low cost, and various structural forms. They are mostly used in large-span workshops in industrial buildings, Long-span corridors, aircraft assembly workshops and large warehouses have high manufacturing and installation requirements, especially the difficulty of installation. Therefore, the construction of long-span space structures is one of the important symbols of a country's architectural technology level. From One aspect reflects the level of construction technology of a country. [0003] Super-long-span steel trusses are often used in heavy industrial plants, stadiums, industrial pipeline corridors, cen...
