Energy-dissipation vibration-reduction self-resetting inhaul cable device of large-span prestressed steel structure
The invention discloses an energy-dissipation vibration-reduction self-resetting inhaul cable device of a large-span prestressed steel structure. Comprising baffles arranged on the left side and the right side, an inhaul cable penetrating through the baffles, a cushion block, an anchorage device, a steel pull rod sequentially penetrating through the left baffle and the right baffle, base plates welded to the two ends of the steel pull rod, a steel strand penetrating through the centroid of the steel pull rod, and a second anchorage device used for anchoring the steel strand. The spiral spring is nested on the outer side of the steel pull rod, the two ends of the spiral spring are welded to the inner sides of the left baffle and the right baffle respectively, the upper staggered moving plate is welded to the inner side of the left baffle, the lower staggered moving plate is welded to the inner side of the right baffle, and the energy consumption device sequentially penetrates through upper strip-shaped bolt holes and lower strip-shaped bolt holes and comprises a screw rod, an upper nut, a lower nut, an upper friction gasket and a lower friction gasket. The device further comprises a friction energy consumption block arranged between the upper dislocation plate and the lower dislocation plate and a check block for preventing the friction energy consumption block from falling off, energy consumption and vibration reduction can be achieved through tension and compression deformation of the spiral spring and relative sliding of the upper dislocation plate and the lower dislocation plate, and the self-resetting function can be achieved through the steel strand in the steel pull rod and the spiral spring.
本发明公开了一种大跨预应力钢结构的耗能减振自复位拉索装置，包括设于左右两侧的挡板、穿过挡板的拉索、锚固拉索的垫块和锚具、依次穿过左右挡板的钢拉杆、焊接在钢拉杆两端的垫板、穿过钢拉杆形心的钢绞线、用于锚固钢绞线的第二锚具、嵌套在钢拉杆外侧且两端分别焊接在左右挡板内侧的螺旋弹簧、焊接在左侧挡板内侧的上错动板、焊接在右侧挡板内侧的下错动板、依次穿过上下条形螺栓孔的耗能装置，耗能装置包括螺杆、上下螺帽和上下摩擦垫片，还包括内置在上下错动板之间的摩擦耗能块、防止摩擦耗能块脱落的挡块，该装置可通过螺旋弹簧的拉压变形以及上下错动板的相对滑动实现耗能减振，可通过钢拉杆内部钢绞线以及螺旋弹簧实现自复位功能。
