Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, and more specifically, to a waterproofing structure for a corner of a basement top plate and an external wall. Background Art

[0002] The corner between the basement roof and the exterior wall is one of the key parts of the building that is vulnerable to moisture damage. In the structure of the basement, the roof is the top structure that isolates the basement from the upper building or the ground, and the exterior wall corner is the corner between the basement wall and the ground or the upper wall. Since the basement is underground, it is easily affected by factors such as changes in groundwater levels and rainwater infiltration. Therefore, waterproofing work on the corner between the basement roof and the exterior wall is particularly important.

[0003] After searching, the Chinese patent with publication number CN218933490U discloses a corner waterproof structure. For the corners of existing houses, due to structural problems, rainwater can easily penetrate into the room through the angle at the junction of two walls, and this angle is not easy to apply waterproof materials. Once the problem of rainwater penetration occurs at the corner, it is very troublesome to deal with it, and it is easy to cause the problem of rainwater penetration again due to the aging of the waterproof material when applying waterproof materials afterwards. Through the combination of baffles, mounting holes, interlocking grooves, interlocking plates, slope plates, filling layers, water guide grooves, slots, plug plates and concrete layers, the waterproof structure is effectively assembled according to the length of the wall, avoiding the waterproof structure being too long or too short and resulting in an incompatible installation on the wall and the corner, and reducing the space occupied by the waterproof structure, thereby improving the convenience of the waterproof structure during transportation.

[0004] However, its corner waterproof structure is single, and when used at the corner of the basement ceiling and the outer wall, it is still easy for moisture to penetrate from the inside of the basement ceiling, causing problems such as moisture and mold growth inside the basement. In severe cases, it may even cause damage to the building structure. Utility Model Content
