Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to an exterior wall waistline waterproof structure. Background Art

[0002] Although the waistline of the exterior wall makes the building more beautiful, the wall at the waistline of the exterior wall is prone to water leakage. The Chinese utility model patent with the authorization announcement number CN206233519U discloses a detailed structure of the waistline of the exterior wall. The patent can effectively reduce the water leakage problem at the waistline of the exterior wall of the building through the cooperation of the outward rainwater slope and the drip corner. However, the outward rainwater slope and the drip corner must have a slope design, the shape is limited, the scope of application is small, and it cannot meet the design requirements of different shapes. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an external wall waistline waterproof structure with flexible design, simple requirements and wider application range.

[0004] In order to achieve the above-mentioned purpose, a waterproof structure of the waistline of an exterior wall is designed, comprising an exterior wall body and a waistline arranged on the outside of the exterior wall body, wherein the waistline is a one-step or multi-step downward structure, and a circular arc chamfer is provided at the connection between the first step structure and the exterior wall body, and further comprises a waterproof membrane layer, wherein the waterproof membrane layer covers the exterior wall body located above the waistline of the step structure, the circular arc chamfer, the top surface of the first step structure of the waistline, and the step surfaces of the remaining waistline step structures.

[0005] The utility model also has the following preferred technical solutions:

[0006] 1. The width of the upper step structure on the waistline is greater than the width of the lower step structure.

[0007] 2. A waterproof insulation layer and an exterior wall surface layer are also provided on the outside of the exterior wall body and waistline. The waterproof insulation layer and the exterior wall surface layer are located on the outside of the waterproof membrane layer, and their shapes match the waistline of the step structure. A drip hole is provided at the bottom of the exterior wall surface layer where it matches the last step structure, and the drip hole is set away from the waistline of the step structure.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. The water on the upper part of the waistline can be guided by the arc chamfer and flow away from the outer wall. And because the width of the step structure on the upper part of the waistline is greater than that of the lower part, the water flow will not affect the wall below the waistline.

[0010] 2. Even if the water flows back to the inner side of the wall, it can be guided to drip at the drip hole;

[0011] 3. There is no strict slope restriction on the waistline, and the step structure can be designed to any number. It only needs to ensure that the width of the upper step structure is greater than the width of the lower step structure. Therefore, this waterproof structure design is more flexible, the requirements are simple, and the scope of application is wider. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural diagram of the utility model;

[0013] In the figure: 1. Exterior wall; 2. Waistline; 3. First step structure; 4. Arc chamfer; 5. Waterproof membrane layer; 6. Waterproof insulation layer; 7. Exterior wall surface layer; 8. Drip hole. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings. The structure and principle of the utility model are very clear to people in the field. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] like Figure 1 As shown, in the exterior wall waistline waterproof structure of the present invention, the waistline 2 of the exterior wall 1 is a one-step downward structure, and can also be designed as a multi-step downward structure. It should be noted that the width of the upper step structure of the waistline 2 is greater than the width of the lower step structure.

[0016] Figure 1 In the example shown, the waistline 2 is a two-stage step structure. Figure 1 In the figure, the connection between the first step structure 3 of the waistline 2 and the external wall 1 is provided with an arc chamfer 4. The external wall 1, the arc chamfer 4, the top surface of the first step structure 3 of the waistline and the step surfaces of the remaining waistline step structures are covered with a waterproof roll material layer 5, which plays a role in waterproofing and leakproofing.

[0017] A waterproof insulation layer 6 and an exterior wall surface layer 7 are also provided on the outside of the exterior wall body 1 and the waistline 2. The waterproof insulation layer 6 and the exterior wall surface layer 7 are located on the outside of the waterproof membrane layer, and their shapes match the waistline 2 of the step structure. The exterior wall surface layer 7 is located on the outside of the waterproof insulation layer 6. A drip hole 8 is provided at the bottom of the exterior wall surface layer 7 where it matches the last step structure. The drip hole 8 is set away from the waistline 2 of the step structure.

[0018] The water on the upper part of the waistline 2 can flow away from the outer wall 1 through the guidance of the arc-shaped chamfer 4, and because the width of the step structure on the upper part of the waistline 2 is greater than the width of the step structure on the lower part, the water flow will not affect the wall on the lower part of the waistline 2. Even if the water flows back to the inner side of the wall, it can be guided to drip at the drip hole 8.

[0019] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
