Consult Fig. 1, Fig. 2 earlier, damping vibration abatement 3 of the present invention, be characterized in that this device 3 is made up of cover plate 31, spin 32, annular elastic body 33 and alms bowl body 34, this alms bowl body 34 has at the bottom of the concave arc shape 343 and the cylindrical shell 341 of band round platform 342, annular elastic body 33 is placed in the cylindrical shell 341 of said alms bowl body 34 and on the round platform 342, spin 32 is placed at the bottom of the concave arc shape of alms bowl body 34 on 343, the bottom surface of cover plate 31 is provided with and the corresponding groove 311 of the spherical crown of spin 32, utilizes this groove 311 to cover on spin 32.
343 make for steel plate at the bottom of the concave arc shape of said alms bowl body 34.
Said annular elastic body 33 adopts rubber-plastics material to make.
Said spin 32 both can be stainless steel or other metal high strength spheroids, also can be high-intensity nonmetal spheroid.
Said cover plate 31 is made by hard metal material or high strength hard nonmetals.
But said damping vibration abatement 3 not only single-piece uses, and also can make the shockproof combination order 6 of a kind of damping, as shown in Figure 3, is about to a plurality of damping vibration abatement 3 usefulness concrete 62 and waters and be filled in the steel disk 61 and make.
Utilize described damping vibration abatement to carry out the job practices of damping quake-proof building, it is characterized in that the step of this method is as follows:
1. beat foundation pile 42 for building according to a conventional method;
2. the number of plies, structure, size, the shape according to the building that will build designs, the quantity and the layout of reasonable disposition damping vibration abatement 3, and the alms bowl body 34 with damping vibration abatement 3 is placed in the top layer 41 of pile foundation part 4 in view of the above;
3. carry out the 41 disposable reinforced concrete soil scene pourings of pile foundation part 4 top layers, form one with said foundation pile 42 and alms bowl body 34;
4. damping vibration abatement 3 is installed, particularly, promptly is:
Annular elastic body 33 is placed in the cylindrical shell 341 of alms bowl body 34 and on the round platform 342;
With spherical groove 311 upper shields of cover plate 31 on spin 32;
5. the top layer 41 with pile foundation 4 waters holistic foundation 2 in the scene successfully with cover plate 31 discretely;
6. carry out other building operations then according to a conventional method.
In the above-mentioned job practices, the 2., 3., also can directly shockproof combination order 6 of damping and the 41 disposable reinforced concrete soil scenes pourings of pile foundation part 4 top layers be integral in 4..
The 5. the step is after laying one deck elastic layer 5 on the top layer 41 of pile foundation part 4 in the above-mentioned job practices, as shown in Figure 5, on this elastic layer 5 and cover plate 31, carry out the cast-in-place filling of whole foundation 2 again, and after cover plate 31 fuses with foundation 2,6. carry out routine more set by step and construct.
In above-mentioned job practices, step in 2. be on the top of each foundation stake 42 with concrete casting and fix the shockproof combination order 6 of a damping, as shown in Figure 6,6. construction set by step then.
When earthquake takes place, strong seismic wave makes building be subjected to the power of horizontal direction, because building and foundation 2 are released states with pile foundation part 4, will inevitably produce the horizontal relative displacement of horizontal direction between the two, spin 32 is supporting cover plate 31 and building foundation part 2, when making lateral displacement with pile foundation part 4, inevitable 343 arching trajectory at the bottom of the concave arc shape and moving, make whole building 1 and foundation 2 do to lift motion, till running into annular elastic body 33, the effect of described elastic body 33 is the kinetic energy that can absorb a part of building 1 and foundation 2 transverse movements, simultaneously again standard the horizontal limit displacement of foundation 2.Building 1 and foundation 2 that quality is huge must consume very big energy when doing length travel.Because the suffered destruction of the undulatory motion of the vertical direction that building produces because of the effect of earthquake suffered destruction when making horizontal motion.By the absorption and the conversion of energy, can guarantee the safety of building when earthquake like this, reach the shockproof purpose of damping.
