砖壳防水屋面施工方便,造价低廉,防水效果好,使用年限长,维修方便并具有一定的保温隔热性能,可广泛用于屋面坡度为3%～5%的平屋面防水层。一、砖壳防水屋面的防水原理砖壳防水屋面的主要材料是粘土砖,其几何尺寸小、孔隙率大、吸水性好、随温度变化其变形很小,可在砖与砖的灰缝内得到调节,不致使防水层产生裂缝而渗水,即使出现少量渗水,因砖本身的吸水率可达25%～30%,高的可达40%,砖体可吸收少量渗水而不致漏入室内,整个
Brick waterproof roof construction is convenient, low cost, waterproof effect, long service life, easy maintenance and a certain degree of thermal insulation properties, can be widely used for roofing slope of 3% to 5% of the flat roof waterproof layer. First, the waterproof principle of waterproof brick roof The main material of brick waterproof roof is a clay brick, its small geometric size, porosity, good water absorption, deformation with temperature is very small, can be in the brick and brick gray seam It can be adjusted so as not to cause cracks in the waterproof layer and water seepage. Even if there is a small amount of water seepage, the water absorption rate of the brick itself can reach 25% to 30%, and the height can reach 40%. The brick body can absorb a small amount of seepage without leaking into the room. entire
