FLAT ROOF DRAINAGE METHOD
100011 This application claims priority of Chinese Paten on No. 202010878605.6, titled "FLAT ROOF DRAINAGE METHOD", filed with the China National Intellectual Property Administration on August 27, 2020, which is incorporated herein by reference in its entirety.
TECHNICAL FIELD
100021 The present application relates to the technical field of drainage of fiat roofs, and in i 0 particular to a flat roof drainage method.
BACKGROUND
100031 At present, leakage is a serious problem in a building roof, and a key link in roof waterproofing treatment is to ensure smooth drainage_ Referring to Figure 1, a. slope making layer 01 of a flat roof refers to a certain gentle slope built according to a designed drainage direction, which collects water into a roof drainage ditch commonly known as "gutter" or "cave gutter", and the water is finally discharged through the drainage port, to dredge rainwater from the roof to a rainwater drainage system of a building and city 100041 According to requirement of the building code, a slope of the slope making layer 01 of a roof building ranges from 1.5 to 5 degrees, and a thickness of the thinnest part of the slope making layer Dl is 50nun. The slope making layer Cl should be made of lightweight aggregate concrete with a strength grade of not less than ITC15, or tine stone concrete with a strength grade not less than C20, or cement mortar with a strength grade not less than MI5_ The slope making layer 01 generally adopts light construction materials, such as ceramsite and foamed concrete block to perform setting, to reduce a roof load. However, light construction materials all have strong hydrophilicity. Once a roof waterproof layer is damaged, the entire slope making layer 01 may be filled with water, a roof aquifer is formed, which may cause continuous leakage of the roof. In addition, an average thickness of the slope making layer ranges from 60rnm to 120mm, the roof load is relatively large.: and the constniction cost is relatively high, therefore, cancellation of the slope making layer may not only save the construction cost, but also reduce the hidden danger of root leakage. -1 -
[0005] In an existing building roof maintenance project, since water is accumulated in local areas of the roof, the following process is generally adopted, in which the slope making layer is reset, and a leveling layer, a waterproof layer and a protective layer are respectively set, which may not only increase load of a roof mechanism and bring hidden safety danger to the building structure, but also greatly increase the construction cost.
[0006] In an exposed, waterproof and heat insulation integrated light roof system that adopts waterproof coating and heat insulation coating as the main materials, a roof drainage ditch is a first part to be damaged. Due to the dust and dirt deposited in the drainage ditch, which may harden and crack after being dried out, the heat insulation coating may delaminate.
