［摘要］在GB/T 9978-1—2008标准升温条件下，进行了隔震层防火墙防火构造耐火试验及与直径1 200mm橡胶隔震支座的防火构造耐火试验，考察耐火时间对隔震层防火墙防火构造及隔震支座表面温度的影响。试验结果表明：隔震层防火墙防火构造耐火4h，完整性和隔热性完好；隔震支座防火构造耐火3h，隔震支座表面温度最高为103-6℃，隔震支座外观完好。通过拟静力试验，考察了隔震层防火墙防火构造在地震力作用下的可恢复性，证明了建筑隔震防火构造是可靠的。

Abstract:Under GB/T 9978-1—2008 standard heating condition,  fire resistance test on the isolation layer firewall fire protection construction was conducted as well as fire resistance test on fire protection construction with rubber isolation bearing of 1 200mm diameter,  to inspect the influence of the fire resistance time on isolation layer firewall fire protection construction and surface temperature of isolation bearing. The test results show that: the fire resistance time of isolation layer fire protection construction is 4h,  and integrity and thermal insulation is intact. Fire resistance time of fire protection construction of isolation bearing is 3h. The isolation bearing′s surface temperature is up to 103-6℃ and isolation bearing appearance is intact. Based on the quasi static test,  the recovery of the isolation layer firewall fire protection construction was investigated under the earthquake,  which proves that the building isolation fire protection construction is reliable.

Keywords:isolation fire protection construction； fire resistance test； fire resistance time
