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。
In the GB / T 9978.1-2008 standard temperature conditions, the fireproof structure of the fireproof insulation test of fireproof firewall and the fireproof structure fireproof test with the diameter of 1 200mm rubber isolated bearings were carried out. Impact of bearing surface temperature. The test results show that the fireproof structure of the isolation fireproof wall is 4h fireproof and the integrity and heat insulation are intact. The fireproof structure of the shockproof bearing fireproof structure is 3h, the surface temperature of the shockproof bearing is up to 103.6 ℃, and the appearance of the shock absorbing bearing is intact. Through the quasi-static test, the recoverability of the fireproof structure of the seismic isolation firewall under the earthquake force was investigated, and it was proved that the seismic isolation and fireproof construction of the building is reliable.
