Roof waterproof protection layer anti-cracking bin-dividing pouring method
The invention belongs to the technical field of roof waterproof construction, and particularly relates to an anti-cracking separated bin pouring method for a roof waterproof protection layer. Comprising the following steps that S100, after waterproof construction of the roof coiled material is completed, the waterproof surface of the coiled material is coated with a waterproof layer; s200, dividing the positions of dividing joints on the waterproof layer according to the positions of roof rainwater pipes and the drainage gradient and the distance not larger than 6 m, and popping up a control line; s300, waterproof strips are pasted to the positions of the separation seams, and the two sides of the separation seams are fixed by using cement mortar to form slopes; s400, after the waterproof strips are installed, mortar cakes are pasted in the divided lattices according to the thickness of a concrete protection layer and the drainage gradient, concrete pouring is carried out according to lattices, intervals and bins during concrete pouring, and concrete pouring is carried out twice; and S500, during concrete pouring, the anti-crack steel wire mesh is pressed internally, and after concrete pouring is completed, secondary surface finishing is conducted before initial setting, and surface cracks are eliminated. According to the method, cracks of the thin and fine aggregate concrete protective layer of the roof are effectively avoided.
本发明属于屋面防水施工技术领域，具体涉及一种屋面防水保护层防开裂分仓浇筑方法。包括以下步骤，S100：屋面卷材防水施工完成后，在卷材防水表面涂刷一层防水层；S200：在防水层上按屋面雨水管位置及排水坡度按不大于6m的间距划分分格缝位置并弹出控制线；S300：在分隔缝位置粘贴防水条，分隔缝两侧使用水泥砂浆抹成斜坡固定；S400：防水条安装完成后在划分的格内按照混凝土保护层厚度及排水坡度贴灰饼，混凝土浇筑时按照分格间隔分仓进行混凝土浇筑，混凝土浇筑分两次进行；S500：混凝土浇筑时内压抗裂钢丝网，混凝土浇筑完成后在初凝前进行二次收面消除表面裂纹。本发明有效的避免了屋面薄细石混凝土保护层裂缝、裂纹的产生。
