Large-span steel structure single-layer spherical reticulated shell roof structure and construction method thereof
The invention discloses a large-span steel structure single-layer spherical reticulated shell roof structure and a construction method thereof.The spherical reticulated shell roof structure comprises a steel structure single-layer spherical reticulated shell, a circle of main supports and a circle of auxiliary supports, and the main supports and the auxiliary supports are used for fixing the steel structure single-layer spherical reticulated shell to a concrete structure floor; the steel structure single-layer spherical reticulated shell is divided into an upper part and a lower part through an annular support ring beam, reticulated shell nodes formed by welding the steel structure single-layer spherical reticulated shell and the support ring beam are upper supporting nodes and are formed by welding a plurality of rectangular rod pieces and circular steel pipes in a radial shape, and the rest of the reticulated shell nodes are common nodes. A plurality of rectangular rod pieces are radially welded with the circular pipe sections to form a drum-shaped net-shaped node form. According to the invention, a plurality of rod pieces in the latticed shell node are intersected at one point, additional bending moment is not generated, the stress is reasonable, and the bearing capacity and the stability are improved. Besides, the support ring beam is formed by splicing the circular steel pipes in sections, each section of the support ring beam is supported on the main support, and then final welding is completed, so that the high-altitude operation time is shortened, and the safety is improved.
本发明公开了一种大跨度钢结构单层球面网壳屋面结构及其施工方法，球面网壳屋面结构包括钢结构单层球面网壳和用于将其固定在混凝土结构楼层上的一圈主支座和一圈副支座，所述钢结构单层球面网壳由环形的支座环梁分成上下两个部分，与所述支座环梁焊接形成的网壳节点为上支撑节点，由多根矩形杆件呈放射状与圆形钢管焊接形成，其余网格节点为普通节点，由多根矩形杆件呈放射状与圆管段焊接形成鼓形网状节点形式。本发明，网壳节点中多根杆件汇交于一点，不产生附加弯矩，受力合理，提高承载能力和稳定性。另外，支座环梁采用圆形钢管分段拼接，每段支座环梁均支撑在主支座上，然后完成最终焊接，减少高空作业时间，提高了安全性。
