摘　　要：建筑平屋面面层的常规做法多为细石混凝土刚性保护层,但刚性保护层容易开裂,会严重影响屋面防水及使用寿命。为此,介绍一种屋面刚性保护层小分格施工方法,在稍稍增加前期施工成本的情况下,大大降低了混凝土刚性保护层的开裂概率,减少了后期的使用维护成本,取得建筑全寿命周期考量下的社会效益和经济效益。The conventional practice of building flat roofing is mostly a fine protective layer of fine aggregate concrete. However,the rigid protective layer is easy to crack,which will significantly affect the waterproofing and service life of the roof.To this end,a small-grid construction method for roof rigid protective layer is introduced.Under the condition of slightly increasing the pre-construction cost,the cracking probability of the concrete rigid protective layer is greatly reduced,the subsequent maintenance cost is reduced while the social and economic benefits is obtained under the consideration of overall building life cycle.
