Abstract

The invention discloses a low-steel-content ultra-large-span steel structure system based on a high-precision plane truss. A part of the truss is replaced by steel wire ropes through prefabricated assemblies and field hoisting, and the installation efficiency is greatly improved; meanwhile the ultra-large-span requirement can be met; a plurality of span frames are distributed in parallel at equal intervals, longitudinal connecting frames are perpendicular to the span frames, the multiple longitudinal connecting frames are arranged at equal intervals and matched with the span frames to form double-layer square grid structures, and the structure of the longitudinal connecting frames is similar to that of the span frames; upper rods and lower rods of the longitudinal connecting frames are straight rods, the two ends of the upper rods and the two ends of the lower rods are fixedly connected with upper chords and lower chords of the span frames, and zero rods and web rods are further arranged between the upper rods and the lower rods; the upper sides of the square grid structures are connected through crossed diagonal draw bars, and the lower sides of the square grid structures are connected together through crossed flexible steel wire rope structures; and guide rails are parallel to the span frames, the multiple guide rails are longitudinally arranged at the tops of the span frames at equal intervals, and a film is arranged between every two adjacent guide rails.

Description

technical field [0001] The invention relates to a low-steel-content super-large-span steel structure system based on a high-precision plane truss, belonging to the technical field of steel structure plane trusses. Background technique [0002] As the application scenarios of truss structures become wider and wider, the span of trusses becomes larger and larger, making the construction process more and more difficult. It is difficult for traditional construction methods to meet the requirements of super-large spans. Powerless. Contents of the invention [0003] The present invention overcomes the shortcomings of the prior art and provides a low-steel-content super-large-span steel structure system based on high-precision planar trusses. Through prefabricated components, on-site hoisting, and steel wire ropes instead of part of the trusses, the installation efficiency is greatly improved. At the same time, it can meet the requirements of super large span. [0004] In order...
