屋面渗漏水是目前普遍存在的问题。实践经验告诉我们,要想搞好屋面防水工作,必须抓好四个环节,即设计——材料——施工——管理。既要有设计合理的防水方案,又要正确地选择好防水材料,既要按施工操作规程精心施工,又要有一套完整的管理措施。 一、刚性屋面渗漏水的原因 1.内因。混凝土是一种人造石材,抗压强度极高,而其抗拉强度很低,受拉时板面容易出现裂缝。同时混凝土板受到高温或低温时也容易产生裂缝。屋面变形引起的裂缝有以下几种情况:(1)由于温差引起的变形裂缝。屋面板在使用过程中,由
Roof leakage is a common problem. The practical experience tells us that if we want to do a good job in waterproofing the roof, we must do a good job in four areas, namely, design-material-construction-management. It is necessary to have a well-designed waterproof solution, but also to properly select the waterproof material. It is necessary to carefully construct according to the construction operation rules and to have a complete set of management measures. First, the reasons for the leakage of rigid roof water 1. Internal causes. Concrete is a kind of man-made stone, its compressive strength is very high, and its tensile strength is very low. When it is pulled, the board surface is prone to cracks. At the same time cracks are easily generated when the concrete slab is exposed to high temperatures or low temperatures. Cracks caused by roof deformation have the following conditions: (1) Deformation cracks due to temperature differences. The roof panel is in use
