Description

Technical Field

[0001] The utility model relates to the technical field of building exterior walls, in particular to a waterproof structure for building exterior walls. Background Art

[0002] With the development of economy, various energy-saving and heat-insulating lightweight wall materials are widely used in the filling wall of frame structure. However, due to the influence of many factors such as materials, processes, technology and management, the problem of water leakage in the exterior wall is becoming more and more prominent. Especially in the southern and coastal areas with more rain, the long-term rain in the rainy season leads to the problem of water leakage in the exterior wall, which affects the strength of the main body of the building and shortens the life of the building.

[0003] At present, the commonly used waterproofing method for building exterior walls is to use waterproof boards, and the construction method is to splice the waterproof boards on the outside of the building exterior walls in an array to achieve waterproofing. However, when the existing waterproof boards are spliced, the joints are sealed by applying waterproof glue. After a period of use, the waterproof glue will age and weather, resulting in poor adhesion deformation and reduced sealing, which will cause water seepage at the joints of the waterproof boards, affecting the waterproofing effect.
