The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment:
Referring to Fig. 1, a kind of pot rubber bearing with damping comprises upper base plate 1 and following seat board 9.Following seat board 9 is the hollow short quadrangular shape of open top bottom lock, and hollow position is the cylinder blind hole; Pressure-bearing rubber tile 8, brass sealing ring 7 and middle vibration damper plate 6 are housed in the following seat board 9 from the bottom to top successively.The first half of upper base plate 1 is square top board, and the Lower Half of upper base plate 1 is cylinder.Be provided with corrosion resistant plate 5 between the middle vibration damper plate 6 in the bottom of upper base plate 1 and the following seat board 9.
Referring to Fig. 2, Fig. 3 and Fig. 4, four limits of the top board of upper base plate 1 are equipped with downward flange, and two elastomer block 3 are installed between the outer wall of the inboard of every side flanging and following seat board 9.The bottom of upper base plate 1 is provided with the wearing plate 4 of embedding, directly forms slide surface between wearing plate 4 and the corrosion resistant plate 5, and its friction factor is greater than the friction factor of common sliding support slide surface.Be provided with high-damping rubber circle 2 between the external cylindrical surface of the cylinder of described upper base plate 1 Lower Half and the cylinder blind hole of following seat board 9 upper end, the cross section of high-damping rubber circle 2 is the angle steel shape, and material is the energy-absorbing damping rubber.
Operating principle of the present utility model is as follows:
A kind of pot rubber bearing with damping, when operate as normal, between the wearing plate 4 that the bottom of upper base plate 1 embeds and the corrosion resistant plate 5 slippage can not take place, compressive strain can not take place in the high-damping rubber circle 2 with energy-absorbing function, and the elastomer block 3 of upper base plate 1 flange inside compressive strain can not take place.
When earthquake took place, slippages can take place with corrosion resistant plate 5 in wearing plate 4, because the friction factor of the slide surface between them is greater than the friction factor of common sliding support slide surface, and therefore can earthquake energy; When slippage took place for wearing plate 4 and corrosion resistant plate 5, high-damping rubber circle 2 can be out of shape in compressed generation, thereby absorbs a part of earthquake energy; After the compression of high-damping rubber circle 2 acquired a certain degree, the elastomer block of upper base plate 1 flange inside 3 can contact with the outer wall of following seat board 9, and compressive strain absorbs the energy of earthquake again.
