Large-span steel-concrete lagging jack structure for civil building and construction method of large-span steel-concrete lagging jack structure
The invention discloses a large-span steel-concrete lagging jack structure for civil buildings and a construction method of the large-span steel-concrete lagging jack structure. According to the large-span steel-concrete lagging jack structure, at least two arch foot nodes are arranged on a support cylinder, and at least two floors of floors, arch ribs and arch bottom pull rods corresponding to arch foot node pairs, under-arch hanging rods and on-arch supporting rods are adopted to form a suspended connecting body, two support cylinders are used as a vertical bearing system and a horizontal lateral force resisting system, the stress principle of an arch is utilized, all floor systems are vertically supported by arch ribs and provide lateral stable constraint for the arch ribs in turn, steel trusses of all floor systems can effectively transmit horizontal force to the support cylinders at the two ends of the steel trusses, so that the horizontal force of the steel trusses is effectively transmitted to the support cylinders at the two ends of the steel trusses, the horizontal force of each floor system is transmitted to the support cylinder body by the floor system without the help of the arch rib, so that the arch rib is basically only responsible for vertical support, then the on-arch supporting rod plays a role in supporting each floor system, therefore, the large-span requirement of the suspended connecting body can be met, and the suspended connecting body has the advantages of high structural stability and low cost.
本发明公开了一种用于民用建筑的大跨度钢‑混凝土拱架结构及其施工方法，在支座筒体设置至少两个拱脚节点，并采用至少两层楼盖，对应于拱脚节点对的拱肋和拱底拉杆，拱下吊杆和拱上撑杆，组成悬空连接体，以用两个支座筒体作为竖向承重体系以及水平抗侧力体系，并利用拱的受力原理，使各层楼盖既受到拱肋的竖向支承又反过来为拱肋提供侧向稳定的约束，且各层楼盖的钢桁架可以将其水平力有效传递至两端的支座筒体，使各层楼盖的水平力均由本层楼盖自身传递给支座筒体而无需拱肋帮忙，使得拱肋基本只需负责竖向支承，由此再由拱上撑杆和起到支承各层楼盖的作用，因此，能够满足悬空连接体的大跨度需求，具有结构稳定性高、成本低的优点。
