Saddle-shaped cable carrier single-layer latticed shell structure
The invention discloses a saddle-shaped cable carrier single-layer latticed shell structure. The saddle-shaped cable carrier single-layer latticed shell structure comprises a saddle-shaped rigid latticed shell, an inhaul cable component and a boundary ring beam. The saddle-shaped rigid latticed shell is of a bidirectionally-arranged lattice structure, wherein rods in one direction are arranged along a raised surface of a saddle surface, and rods in the other direction are arranged along a recessed surface of the saddle surface. The edge of the saddle-shaped rigid latticed shell is fixedly connected with the boundary ring beam. The inhaul cable component is composed of a plurality of inhaul cables and clings to the lower side or the upper side of the saddle-shaped rigid latticed shell. Each inhaul cable is arranged along the recessed surface of the saddle surface, and is connected with the saddle-shaped rigid latticed shell through a low-friction inhaul cable joint. Two ends of each inhaul cable are in hinge joint with the boundary ring beam. The saddle-shaped cable carrier single-layer latticed shell structure has the advantages that the saddle-shaped cable carrier single-layer latticed shell structure is formed by combination of a single-layer latticed shell structure and a suspended cable structure, the rigid latticed shell is stressed to apply thrust to the boundary ring beam by applying prestressing force to the inhaul cables, the thrust can be offset by tension of the boundary ring beam mostly, and accordingly, stress of the boundary ring beam is reduced greatly.
