The specific embodiment
Below in conjunction with accompanying drawing the structure of a kind of vibration absorption and isolation support device provided by the invention is done further to specify:
As Fig. 3 and shown in Figure 4 be the structural representation of vibration absorption and isolation support device provided by the invention, its structure comprises: by the top board 2 that is used to carry bridge beam body, intermediate support plate 3, the displacement slide plane 21 that is arranged at the two, and the fixing base-plate 1 of bridge pier and be arranged at intermediate support plate 3 and pot rubber bearing that the pressure-bearing rubber tile 4 of 1 of base-plate constitutes; Be provided with the plastics or the rubber and plastic damping energy dissipation plate 23 that constitute by macromolecular material at base-plate 1 sidepiece that constitutes above-mentioned pot rubber bearing, be fixedly connected on above-mentioned plastics or rubber and plastic damping energy dissipation plate sidepiece and be connected to the damping energy dissipation mechanism that the outer shear plate 24 in the chute 27 of above-mentioned top board 2 bottoms constitutes; Be fixed with the shear pin 25 that prevents relative displacement at above-mentioned top board 2 and 1 of base-plate.
Its operating principle is: when earthquake takes place; Set the earthquake wave line of propagation along among Fig. 4 shown in the arrow; Then shear pin 25 is cut off by seismic forces and top board of being fixed 2 and base-plate 1; The beam body drives top board 2 and slides along antidetonation slide plane 21, and corresponding outer 1 of the base-plate of shearing steel plate 24 and being fixed on the bridge pier produces relative displacement, and drives damping energy dissipation material production shear energy dissipation wherein; As much as possible effectively consume on the top board 2 produce the ruinous earthquake energy between the bridge pier fixed of the bridge beam body of carrying and base-plate 1, reduce earthquake to destruction of bridge.
As shown in Figure 5; The shear pin 25 that constitutes above-mentioned vibration absorption and isolation support device can also be arranged on 3 of top board 2 and intermediate support plates; When the earthquake magnitude of earthquake was higher, shear pin 25 was cut off by seismic forces and top board and the intermediate support plate 3 fixed, and by damping energy dissipation material production shear energy dissipation; Can effectively consume equally on the top board 2 produce the ruinous earthquake energy between the bridge pier fixed of the bridge beam body of carrying and base-plate 1, can effectively reduce earthquake to destruction of bridge.
Constitute in the structure of above-mentioned vibration absorption and isolation support device; In order to improve the isolation property that subtracts of bearing; Improve the anti-seismic performance of bearing; In the actual product design, can be symmetricly set in the both sides (as shown in Figure 4) of top board and base-plate as required with shear pin with by the damping energy dissipation mechanism 28 that damping energy dissipation plate, outer shear plate constitute; Or be separately positioned on four sides (as shown in Figure 8) of top board and base-plate, constitute two-way vibration absorption and isolation support device, the effect of its antidetonation shock attenuation or better.
