Background technique

Buildings are places for living and working, practicality and aesthetics are the most basic requirements, but the problem of roof drainage has not been effectively solved for many years, building roof leakage has become one of the most common quality problems that affect the improvement of people's living standards .

Factors in roof drainage design include: regional design rainstorm intensity and roof slope. Roof drainage usually adopts unorganized drainage or organized drainage. According to the specifications, large and medium-sized roofs and those with special requirements for roof drainage usually adopt organized drainage. For small and medium-sized roofs and those without special requirements for roof drainage, unorganized drainage is usually used. Way. Unorganized drainage, also known as free fall, refers to a drainage method in which roof rainwater falls directly from the cornice to the outdoor ground. It has the advantages of simple structure and low cost. In order to meet the drainage requirements in the design of small and medium-sized roofs, it is necessary to set a drainage cornice and drip line with a certain width on the wall along the direction of the drainage slope, but the rainwater falling freely will splash the wall, and the foot of the outer wall is often eroded by splashing rainwater , affecting the firmness and durability of the exterior wall. Sometimes in order to meet the perfect transition effect between the facade and the roof, and ensure that the wall and facade are waterproof, the roof drainage problem is not considered too much, so that the rainwater flows freely down the wall. At this time, not only the wall is corroded The situation may also affect the traffic on the sidewalk.
