［摘要］在GB/T 9978-1—2008標(biāo)準(zhǔn)升溫條件下，進(jìn)行了隔震層防火墻防火構(gòu)造耐火試驗(yàn)及與直徑1 200mm橡膠隔震支座的防火構(gòu)造耐火試驗(yàn)，考察耐火時(shí)間對隔震層防火墻防火構(gòu)造及隔震支座表面溫度的影響。試驗(yàn)結(jié)果表明：隔震層防火墻防火構(gòu)造耐火4h，完整性和隔熱性完好；隔震支座防火構(gòu)造耐火3h，隔震支座表面溫度最高為103-6℃，隔震支座外觀完好。通過擬靜力試驗(yàn)，考察了隔震層防火墻防火構(gòu)造在地震力作用下的可恢復(fù)性，證明了建筑隔震防火構(gòu)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
