[0002] A flat roof refers to a roof with a slope of less than 10%. It is usually used in modern buildings, especially commercial buildings, industrial plants and multi-story residential buildings. The design and construction of a flat roof need to consider multiple aspects such as waterproofing, insulation, and drainage to ensure the long-term performance and safety of the roof. It has the advantages of good practicality and easy maintenance, and is widely used in the field of housing construction.

[0003] The existing patent number is 201720798464.0, which is a flat roof waterproof construction structure. This patent can form a good warming and cooling effect by setting the insulation layer between the top structural layer and the slope layer of the building. The insulation layer is set under the slope layer and the leveling layer to prevent moisture from directly entering the insulation layer and reducing the insulation effect when the waterproof layer leaks.

[0004] Based on the above, the inventor found that although the patent can achieve the waterproof and thermal insulation effect of the flat roof by stacking various waterproof and thermal insulation structures layer by layer, it is not convenient for later maintenance and drainage is relatively inconvenient. Therefore, in view of this, the existing structure is studied and improved to provide a flat roof waterproof and thermal insulation construction structure and construction method, in order to achieve a more practical purpose.
