Multi-directional deformation resistant prestressed attached cable large-span space structure
The invention discloses an anti-multidirectional-deformation prestressed attached cable large-span space structure which is dragged and stretched through a steel cable, so that external force can be overcome, and the self weight and the cost are greatly reduced; according to the technical scheme, the anti-multidirectional deformation prestress attached cable large-span space structure comprises a plurality of large-span truss structures which are sequentially and longitudinally arranged, every two adjacent large-span trusses are fixed through a connecting rod to form the large-span space structure, each large-span truss structure comprises an arc-shaped chord member, and the arc-shaped chord members are connected through a connecting rod. A plurality of chord members are sequentially connected to form an arch structure, two steel cables with prestress are arranged between the two ends of each chord member, namely a first steel cable and a second steel cable, the first steel cables serve as chords of the chord members, a plurality of supporting rods are arranged on the inner sides of the chord members in the direction facing the arc center, and through holes are formed in the supporting rods in the trend of the chord members. And the second steel rope is connected to the other end of the chord member after sequentially penetrating through the through holes of the supporting rods from one end of the chord member along the inner side of the chord member.
本发明公开一种抗多向变形预应力附索大跨度空间结构，通过钢索牵引拉伸，不仅能克服外力，而且大大降低了自重及成本；采用的技术方案为：抗多向变形预应力附索大跨度空间结构，包括多榀大跨度桁架结构，且多榀大跨度桁架结构依次纵向设置，相邻的大跨度桁架之间通过连杆固定，形成大跨度空间结构，每榀大跨度桁架结构均包括弧形的弦杆，多根弦杆依次连接形成拱形结构，每根弦杆的两端之间均设置有带预应力的两根钢索，即第一钢索和第二钢索，第一钢索作为弦杆的弦，弦杆的内侧朝向弧心的方向设置有多跟支撑杆，支撑杆上沿弦杆的走向设置有贯通孔，第二钢索从弦杆的一端出发沿弦杆内侧从支撑杆的贯通孔依次穿过后连接到弦杆的另一端。
