Description
Technical field
It the utility model is related to architectural vibration-insulation fireproofing technique field, more particularly to a kind of movable fire prevention of vibration isolator rubber bearing
Protective device.
Background technology
Architectural vibration-insulation rubber supporting seat be by multilayer rubber and multilayer steel plates or other materials be alternately superimposed on being combined into every
Device is shaken, is a kind of current earthquake isolating equipment most widely used in the world, technology is most ripe.Shock isolating pedestal is as supporting member
A part, is arranged in the Seismic Isolation of Isolation Layer or Interlayer seismic isolation layer between basis and superstructure, is isolated with this or dissipation seismic energy,
Ensure structure safety.
According to《Code for fire protection design of buildings》(GB50016-2014) for the regulation of civil buildings, fire resistance rating one in
When the column component of level, fire endurance are small not less than 3, a part of the vibration isolator rubber bearing as column component, its fire endurance also should
Reach fire endurance not less than 3 requirements when small.Since vibration isolator rubber bearing is rubber, when fire occurs, with temperature
Degree rise, rubber is gradually degraded, while coheres gradual failure between rubber and steel plate, and last air is between steel plate and rubber
Gap penetrate into and cause vigorous combustion, bearing in a compressed state, rubber steel plate can staggered floor slide, cause bearing constantly to deteriorate
And finally lose bearing capacity, research show its fire endurance only 82 minutes, do not reach far 3 it is small when fire endurance requirement.
Promoted and applied rapidly since last century the eighties as building subtracts seismic isolation technology, China's architectural vibration-insulation engineering quantity
It is more and more, but all kinds of bearings of architectural vibration-insulation in China do not have measurements for fire-protection at present.Shock insulation is built in practical engineering application
Build the Important building that the mostly large public building such as school, hospital and transport hub is crowded place, its Seismic Isolation of Isolation Layer one
Fire occurs for denier, and portion of standoff loses bearing capacity, and superstructure differential settlement may be triggered the serious consequence such as even to collapse,
There are great security risk.
Vibration isolator rubber bearing flameproof protection is first it is ensured that it can ensure normal load-bearing capacity in a fire, and then really
Structure-preserving security, grace time is won for evacuating personnel.Meanwhile fireproof construction should meet that shock isolating pedestal is daily or medium and small shake work
Bearing mobility under condition, and construct without damage.Further the basic mechanical performance decline control of shock isolating pedestal exists after fire
In a certain range.
In recent years, the flameproof protection of architectural vibration-insulation rubber supporting seat has attracted people's attention, such as:One kind fire prevention isolation rubber
Bearing (the patent No.:CN105155671A), a kind of shock insulation fireproof construction and its construction method (patent No.:
201510978269.1), a kind of vibration isolator rubber bearing Novel fireproof and wind resistance combination unit the (patent No.：
201410608417.6), a kind of vibration isolator rubber bearing flameproof protection device (patent No.：201620552240.7), but these are anti-
Fiery guard method there is a problem in that:1) shock isolating pedestal usually fine motion or occur earthquake after, since bearing is subjected to displacement, prevent
Fire construction can destroy, and cause the reduction or forfeiture of anti-flaming thermal-insulation effect.2) due to the limitation of make, in isolation rubber
When big displacement occurs for bearing, fireproof construction is fallen off causes security risk to personnel below bearing.
