Large-span space suspended spoke type truss structure system and construction method
The invention discloses a large-span space suspended spoke type truss structure system and a construction method, and relates to the technical field of civil engineering. The large-span space suspended spoke type truss structure system comprises a dome part, wherein the dome part comprises an upper structure and a lower structure; the lower structure is arranged below the upper structure; the upper structure comprises a central ring truss, a middle ring truss, an outer ring truss, an inverted triangular truss and a secondary truss; and the lower structure comprises an annular cable, a radial cable, a stabilizing cable and a supporting rod. The stability and the bearing capacity of the structure are enhanced, so that the span of the structure is increased, and the advantages of convenient construction, high structural bearing capacity, good stability and the like can be realized. A hydraulic synchronous sliding technology is adopted in construction, a counter-force frame can be abandoned, the reinforcing problem of a counter-force point is solved, time and labor are saved, rigid connection and synchronous control with a moved component are easy to achieve, and the in-place precisionis high. A lower part is composed of the annular cable and the radial cable, a prestressed cable is tensioned by adopting a two-stage cyclic tensioning method, the annular cable is a passive tensioning cable, and the radial cable is an active tensioning cable.
本发明公开一种大跨空间弦支轮辐式桁架结构体系及施工方法，涉及土木工程技术领域，包括穹顶部分，穹顶部分包括上部结构和下部结构；下部结构设置于上部结构的下方；上部结构包括中央环桁架、中部环桁架、外部环桁架、倒三角桁架和次桁架；下部结构包括环向索、径向索、稳定索和撑杆。增强了结构的稳定性与承载能力，使结构在跨度增大的同时可实现施工方便、结构承载力高与稳定性好等优点。在施工中采用液压同步滑移技术，该技术可抛弃反力架，省去了反力点的加固问题，省时省力，与被移构件刚性连接，同步控制较易实现，就位精度高。下部构成为环向索及径向索，采用两阶段循环张拉法张拉预应力索，其中环索为被动张拉索，径向索为主动张拉索。
