摘要为详述澳门百家乐官网房的执拗的功能,本着眼前应用至多的砖混框架创作澳门百家乐官网房的创作点,应用测量法1 000 mm×480 mm×360 mm澳门百家乐官网砌成宽3 000 mm,高3 000 mm,厚400 mm的非承重的澳门百家乐官网壁体作为实验用构件,夸大地直立的执拗的实验炉,用规范火暖和的弯成弧形进步体温,立体构件的执拗的实验。用K型温差电偶记载回火使浮出水面温升,对执拗的实验的执拗的完整性和隔热功能停止了详述。,执拗的限定断定。检验水果象征,非承重澳门百家乐官网壁体具有良好的执拗的功能,执拗的限定不以内3。 h。同时,在这种创作的澳门百家乐官网壁体中,澳门百家乐官网外侧的石膏师层实际上阻拦射出最初的火的逐渐毁坏;金属布片实际上起到紧抱澳门百家乐官网的功能;密集地压实的澳门百家乐官网其胸怀缺勤十足的可助燃的氧,且澳门百家乐官网表皮表露于激情中表格干馏层阻挡了激情增进向其胸怀铺满。A test was conducted in this paper to learn the fire resistant performance of straw bale buildings.Considering the fact that most straw bale buildings used in china were brick frame with 非承重 plastered straw bale wall,a specimen of 非承重 plastered straw bale wall was built with straw bale of size 1 000 mm×480 mm×360 mm.In this test,a vertical fire resistance test furnace was used,a standard temperature rise curve was employed as the heating mode,and the K-tape thermocouple was used to record the temperature rise of the unexposed face during the test.By studying the fire integrity and fire insulation,judge the duration of fire resistance of the specimen.The test results show that the 非承重 plastered straw bale wall has a good fire resistant performance,and the duration of fire resistance is no less than 3.0 h.In this kind of wall structure,the plaster layer stops the invasion of the initial fire 实际上;实际上 steel wire mesh fastens the straw bale 实际上;于是 the insufficient oxygen in the closely compacted straw bale and the layer of char on the surface insulate the straw 上面。
