Description
技术领域technical field
本发明涉及一种受力复杂的大跨度空间结构，更具体的说，是涉及一种高强螺栓空心毂节点的单层网壳结构。The invention relates to a large-span space structure with complex stress, more specifically, a single-layer reticulated shell structure with high-strength bolt hollow hub nodes.
背景技术Background technique
现行《空间网格结构技术规程》(JGJ7-2010)规定，单层网壳应采用刚接节点，如焊接球节点，杆件多采用圆钢管、矩形钢管和H型钢等，目前应用于单层网壳的节点有焊接空心球节点、隔板焊接节点、厚壁钢管节点、相贯节点及铸钢节点等，但是这些节点形式都存在不足。焊接空心球节点、隔板焊接节点和厚壁钢管节点等焊接连接节点需要现场拼装焊接，施工繁琐，不利于建筑工业化的发展，且过多的焊缝会影响节点受力性能；相贯节点对主管和支管的尺寸有一定要求，一定程度上制约了其应用；铸钢节点性能优良但是成本过高，不适于大范围推广应用。因此，需开发一种施工方便快捷，受力性能优良的单层网壳用节点形式。The current "Technical Regulations for Spatial Grid Structures" (JGJ7-2010) stipulates that single-layer reticulated shells should adopt rigid joints, such as welded ball joints, and rods are mostly made of round steel pipes, rectangular steel pipes and H-shaped steel, etc., which are currently used in single-layer grid structures. The joints of reticulated shells include welded hollow ball joints, diaphragm welded joints, thick-walled steel pipe joints, intersecting joints and cast steel joints, etc., but these joint forms have shortcomings. Welded joints such as welded hollow ball joints, bulkhead welded joints and thick-walled steel pipe joints require on-site assembly and welding, which is cumbersome to construct and is not conducive to the development of building industrialization, and too many welds will affect the mechanical performance of the joints; The size of the main pipe and the branch pipe has certain requirements, which restricts its application to a certain extent; the cast steel joint has excellent performance but the cost is too high, which is not suitable for large-scale application. Therefore, it is necessary to develop a joint form for single-layer reticulated shells that is convenient and fast in construction and has excellent mechanical performance.
