Bidirectional oblique crossing combined spoke type tension cable truss system and application

Abstract

The invention discloses a bidirectional oblique crossing combined spoke type tension cable truss system and application. The bidirectional oblique crossing combined spoke type tension cable truss system comprises a bidirectional oblique crossing cable truss combination body, a double-layer inner ring inhaul cable combination body, a single-layer outer ring pressing beam and oblique crossing landing supporting columns. The bidirectional oblique crossing cable truss combination body is formed by intersecting and converging oblique crossing cable trusses in the forward direction and the reverse direction in the circumferential direction and sharing a vertical supporting rod, and has great torsional rigidity. The double-layer inner ring inhaul cable combination body comprises an upper inner ring cable, a lower inner ring cable, an inner ring supporting rod and an inner ring stay cable, and the stay cable is used for roof curved surface modeling; the single-layer outer ring pressing beam isin a pressed state and is arranged along the whole circle of the outer ring boundary; and the oblique crossing landing supporting columns provide vertical support for the cable truss system. Based onthe cooperative mode of a spoke type tensioning self-balancing system composed of the bidirectional oblique crossing cable truss, the inner ring inhaul cable and the outer ring pressing beam, the spoke type tensioning self-balancing system is supported on the oblique crossing floor supporting columns, part composition modules are clear, force transmission is clear, and the bidirectional oblique crossing combined spoke type tension cable truss system has the advantages of being high in torsional rigidity and bearing capacity and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a two-way obliquely combined spoke type tension cable truss system. Background technique [0002] The cable-strut-beam-membrane system is a novel rigid-flexible combined space long-span structural system. The prestressed setting of flexible members of cables and membranes and the support of rigid members of rods and beams form a bearing structure with a specific initial geometry and overall load-bearing stiffness. force mode. Due to its light weight, large span, both the rationality of structural force and the artistic expression of architectural modeling, it is widely used in large-span roof structure systems such as stadiums. [0003] Tensile self-balancing system is one of the more important spatial long-span structural forms, and the self-balancing structural type is composed of tension members combined with boundary compression rigid members accor...

Problems solved by technology

This type of combined form has relatively high torsional rigidity, but there are also problems such as many nodes meeting and intersecting components, complex connection structure, complex system stress, and high requirements for construction tension forming. Reasonable and effective form structure and construction tension scheme are also to ensure its bearing capacity an important factor in performance
