Waterproof construction method for flat roof
The invention provides a waterproof construction method for a flat roof, which comprises the following steps: building a roof panel frame through steel bar construction and template construction; waterproof concrete is poured in the roof panel frame to form a roof panel; a waterproof agent is sprayed on the surface of the roof panel, and a waterproof layer with the thickness not smaller than 1.5 mm is formed; the waterproof agent is prepared as follows: after the waterproof agent is solidified and dried, fine stone waterproof concrete is poured to form a waterproof concrete layer; the thickness of the fine stone waterproof concrete is 40-60 mm; before the waterproof concrete layer is solidified, a heat preservation layer is arranged; and a decorative surface layer is arranged on the top of the heat preservation layer, and waterproof construction of the flat roof is completed. The rigid waterproof layer and the concrete structure self-waterproof layer are adopted as two waterproof fortification of a water-based mud material, the compatibility of the rigid waterproof layer and the concrete structure self-waterproof layer is good, the quality defects of water channeling, cracks, honeycomb dog holes and the like are fundamentally overcome, concrete cracking is reduced, the concrete strength and the impermeability and waterproof performance are improved, and therefore the waterproof leakage problem of a building roof is radically solved.
本发明提供了一种平屋面的防水施工方法，包括：通过钢筋施工和模板施工，搭建屋面板框架；在屋面板框架内浇筑防水混凝土形成屋面板；在屋面板的表面喷涂防水剂，形成厚度不小于1.5mm的防水层；防水剂包括：待防水剂凝固干燥后，浇筑细石防水混凝土形成防水混凝土层；细石防水混凝土的厚度为40‑60mm；待防水混凝土层凝固前，设置保温层；在保温层的顶部设置装饰面层，完成平屋面的防水施工。本发明采用刚性防水层与混凝土结构自防水同为水基泥材质的两道防水设防，二者相容性好，从根源上解决了“窜水”、“裂缝”、“蜂窝狗洞”等质量缺陷，降低混凝土开裂，提高混凝土强度和抗渗防水性能，从而根治建筑屋面防水渗漏问题。
