Large-span cable net structure supported by self-balancing arch truss
The invention relates to the technical field of large-span structures, in particular to a large-span cable net structure supported by a self-balancing arch truss. According to the structure, a framework is formed by utilizing a small number of transversely-arranged self-balancing arch trusses and longitudinally-arranged longitudinal connecting trusses, cable net systems among the self-balancing arch trusses and the longitudinal connecting trusses are supported, an efficient large-span structure is formed, the number of steel components is greatly reduced, and installation and construction worksuch as on-site welding, hoisting and sliding is greatly reduced. The structure is supported on concrete columns or steel columns and can provide enough space for equipment operation, arch truss supports slide in the transverse direction, transverse deformation of the arch trusses is restrained through transverse steel cables at the supports, the arch trusses have the stress characteristic of thearch trusses under the action of a downward load, and the arch trusses do not generate transverse horizontal thrust on lower columns.
本发明涉及大跨度结构技术领域，尤其是涉及一种自平衡拱形桁架支承的大跨度索网结构。该结构利用较少数量横向布置的自平衡拱形桁架和纵向布置的纵向联系桁架形成骨架，支承其间的索网系统，形成高效的大跨度结构，大幅度减少了钢构件数量和现场焊接、吊装和滑移等安装施工工作。该结构支承于混凝土柱或者钢柱上，能够为设备运行提供足够的空间。拱形桁架支座沿横向滑动，通过支座处的横向钢索约束拱桁架的横向变形，在向下荷载作用下拱形桁架具有拱的受力特性，并且拱形桁架不对下部柱子产生横向水平推力。
