Low-friction stay rope joint for suspension cable single-layer reticulated shell structure
The invention discloses a low-friction stay rope joint for a suspension cable single-layer reticulated shell structure. The low-friction stay rope joint comprises sliding wheels and ear plates; the sliding wheels are rotatably connected to the ear plates arranged at both sides of the sliding wheels by hinge pins; the ear plates are fixedly connected above and below a rigid reticulated shell of the suspension cable single-layer reticulated shell structure; stay ropes of the suspension cable single-layer reticulated shell structure are clung to the lower parts of the sliding wheels. By the low-friction stay rope joint, the rigid single-layer reticulated shell structure is connected with a suspension cable structure together to form suspension cable single-layer reticulated shell structure; by matching of the stay ropes and the sliding wheels, the low-friction stay rope joint for the suspension cable single-layer reticulated shell structure takes a supporting effect on the rigid reticulated shell; moreover, in the tensioning process of the stay ropes, the sliding wheels can freely slide, so that the friction force of the joint is small, and thus, loss of a prestress can be effectively reduced. According to the invention, not only is reliable connection of the stay ropes and the rigid reticulated shell ensured, but also application of the stay rope prestress in the construction tensioning process is ensured.
