Single-circle supporting rod spoke type truss string structure system
The invention discloses a single-circle supporting rod spoke type truss string structure system which comprises a truss system, a single-layer cable system and supporting rods. The truss system is composed of radial trusses and annular connecting components. The single-layer cable system is composed of annular cables and radial cables. The ring cable is positioned below the truss system; the radial cables are located under the radial trusses, one ends of the radial cables are connected with the outer boundary of the roof structure, and the other ends of the radial cables are connected with the ring cables. The supporting rods are located between the truss system and the single-layer cable system and play a role in connecting the truss system and the single-layer cable system to form an integral roof structure. The truss system and the single-layer cable system are combined, prestress is applied to the single-layer cable system, supporting points can be provided for the truss system through the supporting rods, and the span of the whole truss system is reduced; on the other hand, by means of the characteristic that the truss is large in spanning capacity, only a set of supporting rods can be arranged at the endless cable of the single-layer cable system, no supporting rod is arranged between the endless cable and the outer boundary, and therefore the number of the supporting rods of the whole structure is greatly reduced compared with a traditional spoke type string structure.
本发明公开了一种单圈撑杆轮辐式张弦桁架结构体系，其包括：桁架系、单层索系和撑杆；桁架系由径向桁架和环向联系构件组成；单层索系由环索和径向索组成；环索位于桁架系的下方；径向索位于各榀径向桁架的正下方，一端与屋盖结构的外边界相连，另一端与环索相连；撑杆位于所述桁架系和所述单层索系之间，起到联系二者、形成屋盖整体结构的作用。本发明将桁架系与单层索系结合，通过对单层索系施加预应力，可以使其经由撑杆为桁架系提供支点，减小整个桁架系的跨度；另一方面，利用桁架跨越能力大的特点，可以仅在单层索系的环索处设置一组撑杆，而在环索和外边界之间不设置撑杆，从而使整个结构的撑杆数量相对传统轮辐式张弦结构大幅减少。
