Abstract
The invention discloses a damping seismic isolation and reduction device for building, which is characterized by comprising two seismic isolation units which are vertically overlaid with each other, wherein each isolation unit is combined by an A part and a B part, contact surfaces of the A and the B parts are provided with one or more guide rails and chutes which are relative concavely and convexly, the side surfaces of the chutes vertical to the sliding direction of the guide rails are provided with one or more elongated openings, a metal bar rubber block is inserted in each elongated opening, and the two ends of the metal bar rubber block are provided with steel bars. Acting force of seismic wave horizontal components to the buildings provided with the damping seismic isolation and reduction device can be reduced and isolated under this precondition that the buildings on the upper portions and the foundations can be effectively connected, thereby being capable of more securely achieving no collapsing in large earthquakes and no damage in middle earthquakes. Because the maximum displacement of the damping seismic isolation and reduction device is limited by a steel structure, rubber elastic materials and the like can not be acted by tension and shear, the problem that the buildings and the foundations are cut off caused by rubber fracture does not exist, and the damping seismic isolation and reduction device is safer in itself.
Description
Technical field
The present invention relates to technical field of buildings, specifically a kind of damping that is installed on the building (below be referred to as building) subtracts earthquake isolating equipment.
Background technology
Earthquake has caused huge disaster to the mankind, and it is owing to the irresistible earthquake shock of building that the injures and deaths that most earthquakes cause are destroyed, and supporting member damages due to the building collapsing of back; Because building produces shearing deformation and causes the building structure distortion impaired when receiving seismic wave and impact, more chief reason is that the long horizontal vibration of secondary wave causes the level of building on vertical to be waved; The seismic energy that is transmitted to building top does not have local consumption, can only get back near the basis, if impact just in time stack with seismic wave next time; For frame structure building; Impulse force after the stack has surpassed concrete compressive strength, and the concrete of weak part is broken, has broken the concrete resistance to compression; The rock-steady structure of reinforcing bar tension; Unstability, lose rigid support and cause building collapsing, the infrequent phenomenon of collapsing of steel work then is that above-mentioned seismic forces constantly acts on its weak part, and tension and compression cause the metal fatigue fracture repeatedly; Also possibly be that tension and compression repeatedly cause metal heating, cause physical behavior to change and make whole building collapsing.Certainly, also exist building not according to requirements for fortification against earthquake, steel tensile strength is lower than earthquake shock intensity (house owed by a citizen that has even do not have anti-seismic construction) in building frame or the constructional column, and earthquake resistant structure lost efficacy and causes the house to be toppled over.
Summary of the invention
The objective of the invention is to overcome the deficiency that the long-term pressurized of using always in the existing isolation measure of isolation rubber pad rubber is prone to sheared under aging and the geological process power easy fracture; A kind of vertical maintenance steel work stable support is provided, and the damping displacement that is combined to form by member on the horizontal plane makes earthquake subtracted earthquake isolating equipment to what the impact force of top-out effectively alleviated.
The active force that the present invention is directed to the seismic damage building is respectively in X, Y, three of the Z repercussion that axially comes up; Particularly the active force of Y axle waves through building also has part to be converted into the impact on the plane, and the seismic wave horizontal component is to cause this principle of principal element of building destruction, lets originally subtract the load-bearing of earthquake isolating equipment performance steel work, characteristic that pull resistance is good; When keeping the building vertical stability; Changing of the relative positions mode through device inner part compressing rubber material prolongs geological process power to the time that superstructure is transmitted, and reduces top-out and receives the mode of the acceleration of motion of earthquake shock generation to reduce the impact force of earthquake to the building superstructure; Can movable very stable again " pin " as having loaded onto to building; When obtaining certain horizontal anomalous movement space and keeping certain flexibility, can keep stable rigid support during no external impacts, under the certain intensity assurance of member; The space that is subjected to displacement when guaranteeing building and basic existing external impacts; Can guarantee that again its no external force is a rigidly connected integral body as the time spent, subtract the elastomeric material that plays a major role at a distance from earthquake aspect pressurized not at ordinary times, only when external impacts, just can receive the pressure that does not almost have shearing deformation; There is not the situation of being drawn; Can not increase negative worry for the high level that will consider wind active force factor, super highrise building, member has than longer application life of rubber vibration isolation cushion and more safe and reliable theoretical foundation, and the rubber parts that lost efficacy easy ageing more is as parts that insert separately; Install easily, change, safeguard also convenient.
The technical solution adopted for the present invention to solve the technical problems is: two shock insulation unit that comprise vertical stack each other constitute; Each shock insulation unit is constituted by A spare and B spare; A, two of B have one or more concavo-convex relative guide rails on contact surface (cross sectional shape of guide rail and chute is consistent with chute; Preferred rectangle); Chute is opened one or more strip openings in the side vertical with the guide rail glide direction, and that inserts in each opening that both sides are equipped with rod iron adds the metal bar block rubber.Two assembly of elements revolve each other and turn 90 degrees; The grooved rail of two unit just constitutes a damping for building of the present invention in the projecting into of ground " ten " stack and subtracts earthquake isolating equipment (also can a plurality of unit accumulative total revolve and turn 90 degrees formation, like each rotation 45 degree relatively of three assembly of elements).
In the present invention; Because metal is born the effect of tension and pressure-bearing in the assembly, the pressure when parts carried out damped motion when elastomeric material was only born the seismic forces horizontal impact on the horizontal direction does not have tension, shears phenomenon; Therefore assembly can not cause building and basis to be broken off because of the rubber fracture; Both allowed assembly certain horizontal changing of the relative positions to be arranged two ends up and down, and guaranteed again only to have the controlled stretching (gap of rod iron and opening in the not compression vertically upward of this assembly; Preferably will process an integral body during manufacturing with block rubber; Keep rod iron that certain thickness rubber is arranged up and down), be regarded as for General Purpose Rubber shock insulation pad using on the building of high level, superelevation layer and tuyere area of forbidden zone can not producing any negative effect, more help applying of seismic isolation technology.Because it is the main cause that causes building to damage that seismic wave horizontal impact component destroys, and uses building of the present invention can obtain good shock insulation, anti seismic efficiency.
The mode that the present invention is based on unit construction subtracts at a distance from earthquake; Two parts in centre of two groups of parts can unite two into one in the practical application; Form three parts in upper, middle and lower, intermediate member combine with the mutual changing of the relative positions of upper and lower parts respectively just can in 360 degree scopes, subtract, separated seismic wave horizontal component is to the impact of building.The building that this device is installed can keep under the effective prerequisite that is connected in top-out and basis; Subtract separated to the seismic wave horizontal component to the active force of building; Because the horizontal component of seismic wave is to cause the principal element of building destruction, more sure the accomplishing of building " no collapsing with strong earthquake, middle shake not bad " of this device is installed.Because the maximum displacement of this shock insulation member is limited by steel work, rubber elastomeric material (hereinafter to be referred as rubber) can not receive the effect of tension, shearing, the problem that does not exist the rubber fracture to cause building and basis to be broken off, and device itself is safer.
The present invention can effectively reduce and subtract the risk that earthquake isolating equipment self goes wrong, and helps the popularization of seismic isolation technology, reduces the risk (even can avoid being destroyed) that high earthquake intensity regional architecture thing collapses when earthquake; The great market space is arranged, will produce good economic benefits, owing to can alleviate the destruction of violent earthquake greatly after promoting people's lives and properties to manufacturing enterprise; Also had good social benefit, simultaneously, because the elastomeric material that member uses pressurized when external impacts only; Do not have tension, therefore the quality requirement to elastomeric material is not special height, can not insert the virgin rubber regeneration by a certain percentage after the aging waste tire of automobile fragmentation of sex change with having; Reduce production costs greatly; The guiding that meets government's green, environmental protection and resource regeneration industry, and, because the weight that rubber or other elastic components do not bear top-out at ordinary times; Help prolonging its life-span, it is also very convenient to safeguard, change rubber components simultaneously.
