Annular cable suspended dome structure and tension construction method
The invention discloses an endless cable suspended dome structure and a tension construction method. The endless cable suspended dome structure comprises a ring truss, a single-layer reticulated shell, hub nodes and inhaul cables, and the inhaul cables are connected between the single-layer reticulated shell and the ring truss; a fixing node is arranged between the single-layer latticed shell and the ring truss, a first cable lug plate is fixed to the fixing node, a steel casting is arranged in the middle of the single-layer latticed shell, a second cable lug plate is arranged at the bottom of the steel casting, and the inhaul cable is fixed between the first cable lug plate and the second cable lug plate. The bottom of the hub joint is fixedly connected with a supporting structure, a first connecting lug plate is fixed to the bottom of the supporting structure, and the first connecting lug plate acts on the inhaul cable, so that the inhaul cable forms a folding point. Loss of tensioning prestress of the inhaul cable in the joint and at the end of the joint is avoided, effective transmission of the tensioning prestress is achieved, and the rigidity and the bearing capacity of the whole structure reach design values.
本发明公开了无环索弦支穹顶结构及张拉施工方法，该无环索弦支穹顶结构包括环桁架、单层网壳、毂节点和拉索，拉索连接于单层网壳和环桁架之间；单层网壳和环桁架之间设有固定节点，固定节点固定有索耳板一，单层网壳的中间位置设有铸钢件，铸钢件的底部设有索耳板二，拉索固定在索耳板一和索耳板二之间。毂节点的底部固定连接有支撑结构，支撑结构的底部固定有连接耳板一，连接耳板一作用在拉索上，使得拉索形成折点。避免在节点内部及节点端部造成拉索张拉预应力的损失，实现张拉预应力的有效传递，使整体结构的刚度和承载力到达设计值。
