Large-span structure
The invention relates to a large-span structure, and belongs to the technical field of building structures. The large-span structure comprises a plurality of main structure bodies which are sequentially arranged in the length direction of a building plane, wherein each main structure body comprises an arch truss, every two adjacent arch trusses are connected through a net rack, and purlines used for fixing a roof panel are arranged above the net racks. According to the large-span structure, the two structural forms of the arch truss structure and the net rack structure are combined, the arch truss structure is used for achieving large span, the net rack structure is used for connecting the arch trusses, the economic applicable span range of the net rack structure is fully utilized, the axial distance between the arch trusses is increased, the stability performance outside the arch truss plane is enhanced, meanwhile, the purline span is reduced, the thin-wall purline arrangement of a large-axis-row axis net is achieved, and therefore the manufacturing and installing work amount of the arch trusses is small, the roof panel is convenient, fast and efficient to fix and connect, the construction efficiency is high, and the overall performance of the structure is good.
本发明涉及一种大跨度结构，属于建筑结构技术领域，包括沿建筑物平面的长度方向顺次布置的多个主结构体，主结构体包括拱桁架，相邻拱桁架之间通过网架连接，网架上方设有用于固定屋面板的檩条。本发明将拱桁架结构和网架结构两种结构形式进行结合，利用拱桁架结构实现大跨越，利用网架结构连接各榀拱桁架，充分利用了网架结构的经济适用跨度范围，不仅加大了拱桁架之间的轴向间距，还增强了拱桁架平面外的稳定性能，同时减小了檩条跨度，实现了大轴列轴网的薄壁檩条布置，从而使得拱桁架制造安装工程量少，屋面板固定连接便捷高效，施工效率高，结构整体性能好。
