TECHNICAL FIELD

[0001] The present application relates to the technical field of building wall structure, and particularly relates to a waterproof wall structure. BACKGROUND

[0002] Wall structure is an important part of the building field, and its main function is to enclose the internal space of the building and provide necessary physical protection. With the development of building technology, modern walls not only need to have basic load-bearing and partitioning functions, but also must meet various performance requirements such as waterproofing, thermal insulation, fire resistance and the like. These performances are of great significance to improve the overall quality and comfort of the building. Especially in humid and rainy areas, the waterproof performance of the wall is particularly important, and the thermal insulation performance of the wall in cold areas is more emphasized. However, the traditional wall design often cannot meet the needs of both aspects at the same time, resulting in many problems in the use of the building.

[0003] In order to solve the problems of wall waterproofing and thermal insulation, the following methods are usually adopted in the prior art: one is to enhance the waterproof performance of the wall by adding waterproof paint or waterproof membrane; the other is to improve the thermal insulation effect of the wall by adding thermal insulation materials such as rock wool, foamed plastic and the like. In addition, some technical means combine the two methods, for example, waterproof paint is sprayed on the surface of the wall and then thermal insulation materials are laid, or waterproof and thermal insulation layers are arranged inside the wall. These methods are widely used in practical application in order to achieve good waterproofing and thermal insulation effects.

[0004] Although the above methods improve the waterproofing and thermal insulation performance of the wall to some extent, there are still some obvious defects. First, although the use of waterproof paint or waterproof membrane alone can effectively prevent water penetration, its durability and reliability are poor, and it is easy to fail due to aging or improper construction. Secondly, simply relying on thermal insulation materials to improve the thermal insulation performance of the wall often leads to a decrease in thermal insulation effect due to the water absorption of the materials themselves, and even causes moisture problems inside the wall. CONTENT OF THE INVENTION

[0005] In order to improve the waterproofing and thermal insulation effect of the wall, the present application provides a waterproof wall structure.

[0006] The waterproof wall structure provided by the present application adopts the following technical scheme:
