Description

Technical Field

[0001] The present application relates to the technical field of roof waterproofing, and in particular to a roof waterproofing structure for a building on the roof of an old residential area. Background Art

[0002] Waterproofing is a systematic project, which involves waterproofing materials, waterproofing engineering design, construction technology, building management, etc. Its purpose is to protect buildings from water erosion, protect the internal space from harm, improve the use function of buildings and the quality of production and life, and improve the living environment.

[0003] Roof waterproofing is a common type of waterproofing project. As the name suggests, it is a waterproofing project for the roof, which can greatly reduce the probability of rainwater on the roof penetrating into the house. At present, roof waterproofing is usually achieved by applying waterproof coatings on the roof, pasting waterproof membranes, etc., and the waterproof materials are used to separate moisture from the roof, thereby reducing the probability of rainwater penetrating the roof.

[0004] However, if rainwater stays on the waterproof material for a long time, it will corrode the waterproof material, causing the waterproof material to lose its waterproof effect. Furthermore, the rainwater will also corrode the roof body, and eventually the rainwater will penetrate into the roof body, causing the roof to leak. Utility Model Content

[0005] In order to improve the problem that rainwater accumulates on the roof and contacts the roof for a long time, which easily leads to the failure of the roof waterproofing material, the present application provides a roof waterproofing structure for the roof of an old residential area.
