Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see Figure 1 to Figure 5 As shown, it includes a cover plate 1, a sliding plate 2, a side baffle 3 and a block 4; the two cover plates 1 are placed opposite to each other on the sliding plate 2; the side baffle 3 is between the two cover plates 1 and is close to the Both sides of the sliding plate 2; wherein, two stoppers 4 are welded along the length direction on the cover plate 1; two grooves 6 are arranged in the center of the sliding plate 2; the cover plate 1, the sliding plate 2, and the side stop are fixed by bolts The plate 3 and the block 4 form two "cavities"; there is a lead block 8 formed after the molten lead is poured into the cavity from the lead filling hole 7 to be solidified in the cavity; when the sliding plate 2 reciprocates, the concave Shearing the lead weight 8 in the groove 6 consumes energy.

Abstract

The invention relates to a long-stroke plate-type lead shearing damper, belonging to the technical field of engineering vibration reduction. The long-stroke plate-type lead shearing damper comprises cover plates, a sliding plate, a side baffle plate and baffle plates, wherein the two cover plates are arranged in opposite up and down on the sliding plate; the side baffle plate is arranged between the two cover plates and abuts against the two sides of the sliding plate; the two baffle plates are welded on the cover plates along a length direction; two grooves are arranged in the center of the sliding plate; the cover plates, the sliding plate, the side baffle plate and the baffle plates are fixed by bolts to form two cavities; a regulus lead formed by injecting lead of a molten state into the cavities from a lead-pouring hole and solidifying the lead is arranged in the cavities; and when reciprocating, the sliding plate consumes energy by using shearing regulus lead in the grooves. The invention is suitable for thin layers of industrial and civil buildings, pier top sliding supports of bridge structures and the like. The invention has the advantages of long stroke, stable output power, huge energy consumption, simple structure and convenience of installation and regulation.

Description

technical field [0001] The invention relates to a large-stroke lead shear damper, which belongs to the technical field of engineering shock absorption. Background technique [0002] Structural energy dissipation and shock absorption technology is a new anti-seismic and disaster prevention technology. In the structure using energy dissipation and shock absorption technology, some non-load-bearing members of the structure are designed as special elements with large energy dissipation capacity-dampers. In frequent earthquakes, the structure itself has sufficient lateral stiffness to meet the requirements of use, and the structure is in an elastic state; in rare earthquakes, as the lateral deformation of the structure increases, the damper first enters an inelastic state, resulting in greater damping , concentratedly dissipate the seismic energy of the structure, quickly attenuate the vibration response of the structure, thereby avoiding or reducing the damage of the main struc...
