Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a parapet wall flashing structure. Background Art

[0002] The parapet is a low wall around the roof for safety protection. The intersection of the parapet and the roof needs to be waterproofed. Figure 1 As shown, in the prior art, one end of the metal strip 4 is pressed onto the parapet wall by a cement nail 9, and then the metal strip 4 is pressed onto the parapet wall as a whole by a dividing strip 5. In this arrangement, there is a gap between the upper end of the metal strip 4 and the dividing strip 5, and rainwater easily leaks in from there, causing water seepage. 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 a parapet wall flashing structure.

[0004] In order to achieve the above-mentioned purpose, a parapet flooding structure is designed, comprising a first waterproof roll material layer arranged at the corner of the parapet, a second waterproof roll material layer covering the outside of the first waterproof roll material layer, a metal bead arranged on the side of the second waterproof roll material layer close to the parapet wall body for pressing the second waterproof roll material layer, a dividing strip is also provided on the inside of the parapet wall body, the lower part of the dividing strip is located on the inner side of the second waterproof roll material layer, the metal bead is Z-shaped, the bottom of the metal bead is connected to the parapet wall body, the middle part of the metal bead passes through the dividing strip so that the top of the metal bead presses the dividing strip and the second waterproof roll material layer, the connection between the metal bead and the second waterproof roll material layer below is filled with a sealing gel layer, one end of a mesh cloth is connected to the top of the metal bead, and the other end of the mesh cloth is connected to the parapet wall body.

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

[0006] A shedding plate is also provided inside the dividing strip. After the metal pressure strip passes through the dividing strip and the shedding plate, it presses the shedding plate, the dividing strip and the second waterproof membrane layer.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] The possibility of rainwater infiltration caused by the gap between the upper end of the metal layer and the dividing strip in the prior art is eliminated, the waterproof performance of the parapet is enhanced, and the service life of the parapet is extended. In addition, the structure and principle of the utility model are simple and easy to implement. On the premise of providing better results, it does not increase the labor burden and reduces the cost of production operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural diagram of the prior art;

[0010] Figure 2 It is a structural diagram of the utility model;

[0011] In the figure: 1. First waterproof membrane layer; 2. Second waterproof membrane layer; 3. Parapet wall; 4. Metal pressure strip; 5. Dividing strip; 6. Sealing gel layer; 7. Mesh cloth; 8. Drape board; 9. Concrete nails. DETAILED DESCRIPTION

[0012] 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.

[0013] In order to achieve the above-mentioned purpose, a parapet flooding structure is designed, comprising a first waterproof membrane layer arranged at the corner of the parapet, a second waterproof membrane layer covering the outside of the first waterproof membrane layer, a metal bead arranged on the side of the second waterproof membrane layer close to the parapet wall for pressing the second waterproof membrane layer, a dividing strip is also provided on the inside of the parapet wall, the lower part of the dividing strip is located on the inner side of the second waterproof membrane layer, the metal bead is Z-shaped, the bottom of the metal bead is connected to the parapet wall, the middle part of the metal bead passes through the dividing strip so that the top of the metal bead presses the dividing strip and the second waterproof membrane layer, the connection between the bottom of the metal bead and the second waterproof membrane layer is filled with a sealing gel layer, one end of a mesh cloth is connected to the top of the metal bead, and the other end of the mesh cloth is connected to the parapet wall.

[0014] A shedding board is also provided on the inner side of the dividing strip. After the metal pressure strip passes through the dividing strip and the shedding board, it presses the shedding board, the dividing strip and the second waterproof membrane layer.

[0015] 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.
