Abstract
The invention relates to a damping device, in particular to a damping device made of a polymer damping material. The conventional damping device reduces vibration energy transferred from a foundation of a building through sliding between damping pads made of rubber or metal, so that vibration intensity is reduced to reduce the damage degree of the building; however, the rubber has the defects that the rubber is easy to age and the like, and the common rubber support does not have damping energy dissipation capability, so that a damper is needed to be arranged additionally. The technical scheme is that: the polymer damping device comprises a top plate fixedly connected with the building, a bottom plate fixedly connected with the foundation, and a friction block between the top plate and the bottom plate, wherein the friction block is made of a high damping material, preferably a polymer material; and the bottom plate and the top plate are made of polymer concrete and are fixedly connected through a foundation bolt or a fixing steel bar. The damping device has a scientific, reasonable and simple structure, low manufacturing cost and high practicability, and is safe and reliable.
Description
Technical field
The present invention relates to a kind of damping device, relate in particular to the damping device that a kind of polymer as damping material is made.
Background technology
Tremendous economic loss and casualties that earthquake brings, the importance and the urgency that allow deep the recognizing of people avoid casualties and basic equipments such as minimizing house, traffic to destroy.The scientific research personnel that association areas such as a large amount of Structural Engineerings and earthquake engineering have all been organized in countries in the world sums up all previous earthquake disaster experience, one after another original relevant earthquake resistant design code is reflected on oneself and is revised, and has dropped into great amount of manpower and material resources.Different at present and a kind of new ideas of traditional antidetonation system, the engineering damping hierarchy of control of new mechanism form gradually, and it is divided into Passive Control, ACTIVE CONTROL and mixing control.Seismic isolation technology in the Passive Control is meant in the works bottom and with base surface or bottom interlayer certain earthquake isolating equipment is set, and reduces the transmission of seismic energy toward the top structure, and then alleviates the seismic response of superstructure.Existing earthquake isolating equipment generally adopts the slip between the beam that rubber or metal and spring constitute to subdue the vibration energy that the position, building foundation passes over, and reduces the vibrations earthquake intensity to reach the effect that reduces the building damaged condition thereby reach.But rubber exists shortcomings such as easily aging, and the General Purpose Rubber bearing itself there is no the damping energy dissipation ability, and damper need be set in addition.
Summary of the invention
In order to solve the weak point of existing rubber shock-absorbing device, the present invention proposes a kind of polymer damping device.
A kind of polymer damping device of the present invention is placed in it between building main body and the basis, the floor of this device is fixedly connected on the basis, the top board of this device and building main body or equipment connection.Design one brake pad between top board and base plate.When earthquake taking place or having other sharp poundings part shock energy when the basis is transmitted to be absorbed by base plate and top board and weaken.In addition some energy is absorbed by bed course, and some energy is changed into heat energy by frictional layer and other forms of energy is released, thereby has weakened the destruction to building or main equipment of earthquake or other sharp poundings greatly.
Technical scheme of the present invention is: a kind of polymer damping device, comprise the top board and the base plate that with basic fixed be connected and middle brake pad formation fixedly connected with building, and described brake pad is that high damping material is formed.
Above-mentioned brake pad is that polymeric material is made.
Above-mentioned base plate make with polymer concrete with top board and with stone bolt or fixedly reinforcing bar fixedly connected.
Advantage of the present invention is: can eliminate the heavy damage of violent earthquake to building, because what the brake pad of this device adopted is that the high damping polymeric material is made, thereby avoided the issuable covibration of works, this device can bear normal vertical load at ordinary times.This apparatus structure is scientific and reasonable, simple structure, and low cost, practical, safe and reliable, the scope of application is wide, can be used for building, the antidetonation of dock and large-scale precision equipment and damping.
Description of drawings
-accompanying drawing 1 is a structural representation of the present invention.
Among the figure: lower margin bolt 1, base plate 2, brake pad 3, top board 4.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further analyzed.
As shown in the figure: lower margin bolt 1 is driven underground, and is cast with the base plate 2 of steel concrete thereon, is brake pad 3 between base plate 2 and the same top board 4 by steel concrete cast city.Brake pad three is made for polymer.Building on top board 4.Also can on top board 4, lay giant mechanical and electrical equipment etc., can play the effect of damping antidetonation too.
Claims (3)
1. polymer damping device is characterized in that: comprise with the fixedly connected top board of building and the base plate that is connected with basic fixed and middle brake pad constituting that described brake pad is that high damping material is formed.
2. a kind of polymer damping device according to claim 1 is characterized in that: described brake pad is that polymeric material is made.
