Expandable large-span grid structure and construction method thereof
The invention provides a deployable large-span grid structure and a construction method thereof, and relates to the field of building structures.The deployable large-span grid structure comprises an upper chord member used for forming a deployable large-span grid structure and stand columns installed at the two ends of the upper chord member and used for supporting the upper chord member, the stand columns are provided with folding and unfolding inter-column supporting assemblies, and the upper chord member is provided with folding and unfolding roof truss supporting assemblies; cFRP inhaul cable assemblies are arranged on the foldable roof truss supporting assemblies. Structural assembly is completed in advance, folding and unfolding can be conducted in the longitudinal direction and the transverse direction of the structure, high bearing in the working state and small size in the non-working state can be achieved, transportation is convenient, the turnover efficiency is improved, the labor cost is reduced, and high construction site adaptability is achieved. Longitudinal and transverse spans are determined during design of an existing grid structure and cannot be adjusted at any time according to actual conditions. Due to the folding and unfolding functions, the longitudinal length of the structure can be adjusted according to actual conditions, and the field adaptability is improved.
本申请提供了一种可展大跨网架结构及其施工方法，涉及建筑结构领域，包括用于构成可展大跨网架的上弦杆以及安装于上弦杆两端用于支撑上弦杆的立柱，立柱上设有折展柱间支撑组件，上弦杆上设有可折展屋架支撑组件，可折展屋架支撑组件上设有CFRP拉索组件。本申请预先完成结构拼装，并可沿结构纵向和横向进行折展，能够实现工作状态的高承载、非工作状态的小体积，方便运输、提高周转效率、减少用工成本，具有较高的施工现场适应性。现有的网架结构在设计时已经确定了纵横向跨度，不能根据实际情况随时调整。本发明由于具备折叠和展开的功能，因此可以根据实际情况调整结构纵向的长度，提高了现场的适应性。
