For the inclined roof waterproofing, the self-waterproof capability of the structure itself is the basis of waterproofing. The waterproof treatment at the joints of the leaky detail and the slope control of the water discharged are the key to the construction technology.
Firstly, the reasons for the leakage of the inclined roof are analyzed.
First, the concrete roof panel itself is prone to cracks. The fine stone concrete waterproof layer has small flexibility, and is extremely sensitive to uneven settlement of the foundation, small deformation of the member, vibration and temperature difference of the house, and is likely to cause cracking of the roof and leakage.
Second, the four major influencing factors of waterproof layer design, construction, raw material quality and project management:
1) The inclined roof should pay special attention to the detail node design. If the detailed waterproofing scheme is not properly designed, it will easily cause roof leakage;
2) If the roof waterproof construction is not carefully constructed according to the operation procedures and design requirements, the local local waterproof measures are improper, resulting in poor quality of the leveling layer and the detail node, the thickness of the waterproof layer is not up to the specification, and the construction of the isolation layer and the protective layer is not standardized. Leakage is inevitable;
3) The material material of the raw material is also one of the important factors affecting the waterproof effect. Poor material and mix ratio of cement and aggregate, and poor quality of waterproof materials, are likely to lead to roof leakage;
4) The improper operation procedures of the roof and the management measures such as product protection, maintenance and water storage inspection are not carried out according to the relevant requirements, and the waterproof quality of the roof is not guaranteed.
Through practice summary, the article concludes that for the waterproof roof of the inclined roof, the self-waterproof ability of the structure itself is the basis of waterproofing. The waterproof treatment at the joints of the easy-to-leakage joints and the slope control of the water discharged by the water are the key to the construction technology. We should focus on these two tasks.
