Double-slope multi-section cable string truss structure system

By introducing a double-slope multi-segment cable-stayed truss system into the large-span cable-stayed truss structure and utilizing staggered side cables and intermediate cable struts, the problem of insufficient headroom caused by single-segment cable tensioning is solved, thereby achieving efficient moment resistance and improved stability of the large-span structure.

AI Technical Summary

Technical Problem

In existing large-span tensioned truss structures, the tensioning of a single cable causes the truss to occupy too much space longitudinally and has insufficient headroom, which cannot meet the spatial height requirements of the large-span support system.

Method used

A double-slope multi-section cable-stayed truss structure system is adopted. By arranging multiple rows of parallel first and second space trusses in the space truss structure, the side cables and the middle cables are staggered and connected through the middle cable struts and the side cable struts to form a double-slope truss structure. The middle cables are interspersed between the side cables, and high-strength cables are used as tension members to transfer the compression and bending forces of the truss beams to the tension cables, thereby enhancing the structural stability.

Benefits of technology

It can significantly reduce the vertical deflection of large-span structures, increase indoor clearance height, enhance the structure's ability to resist bending moments, reduce steel consumption, and is suitable for large-span projects.

Abstract

The utility model relates to a double-slope multi-section cable string truss structure system, belongs to the technical field of building structures, and solves the problem that in the prior art, a large-span truss structure occupies a large space in the longitudinal direction, so that the clearance height is too low. The device comprises a cable string truss structure and a supporting structure, the cable string truss structure comprises multiple rows of space truss structures arranged in parallel, side cables, middle cables and truss connecting pipes connected among the multiple rows of space truss structures. The lower portion of the space truss structure is fixedly connected with side cables and middle cables, and the middle cables and the side cables are arranged in a staggered mode. The side cables and the space truss structure are supported through a plurality of side cable supporting rods. The middle cable and the space truss structure are supported through a middle cable supporting rod. The double-slope multi-section cable string truss structure system has the effect that the indoor clearance height of a supporting system is increased on the premise that large-span supporting is achieved.
