Multi-level anti-collapse self-resetting friction energy consumption limiting sliding support device
The invention discloses a multi-level anti-collapse self-resetting friction energy consumption limiting sliding support device. Comprising a support bottom plate, lower limiting devices welded to the two ends of the support bottom plate, lower semicircular rolling shafts welded to the two ends of the support bottom plate, a plurality of lower friction energy dissipation blocks welded to the middle of the support bottom plate, L-shaped sliding grooves welded to the two ends, parallel to the sliding direction of the support, of the support bottom plate, and upper semicircular rolling shafts welded to the two sides of the inner surfaces of the sliding grooves. The upper limiting devices are welded to the two sides of the lower surface of the support sliding top plate, the support lug plates are welded to the upper surface of the support sliding top plate, and the springs and the connecting screw rods are arranged between the upper limiting devices and the lower limiting devices. And on the basis of changing the supporting condition of the structure, the friction energy dissipation capacity and the self-resetting capacity of the structure are improved, so that the large-span steel structure has the multi-level anti-collapse capacity.
