[0002] During the construction process of a building project, the construction quality of the roof waterproofing project is particularly important, especially the treatment of the roof flashing end.

[0003] The traditional flashing treatment is: after laying the waterproof membrane on the parapet, the flashing end is directly fixed and protected with a metal batten board through cement nails.

[0004] The applicant has found that this type of flashing end treatment is very likely to cause quality problems such as coil shedding and hollowing, and is very likely to cause flashing leakage, increasing the cost of subsequent repair treatment.

[0005] Therefore, there is an urgent need for a roof waterproof structure and a construction method thereof to solve the above-mentioned technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a roof waterproof structure and a construction method thereof, so as to solve the technical problem that after the waterproofing coil is laid on the parapet, the flashing end is directly fixed and protected by a metal pressure strip plate through cement nails, which is very likely to cause quality problems such as coil shedding and hollowing, and is very likely to cause flashing leakage, which increases the cost of later repair treatment. The many technical effects that can be produced by the preferred technical solution among the many technical solutions provided by the present invention are described in detail below.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] Figure 1 Schematic diagram of the structure of this embodiment. Figure 1 As shown, this embodiment provides a roof waterproof structure, including a wedge-shaped groove 10 arranged on a parapet 1, a waterproof membrane 2, a sealing structure 3 and a waterproof layer structure 4.

[0044] Among them, the flashing end 20 of the waterproof membrane 2 is placed in the wedge-shaped groove 10. By reserving the wedge-shaped groove 10 on the parapet 1, the adhesion of the waterproof membrane 2 at the flashing end 20 and the base layer can be guaranteed to the maximum extent, effectively avoiding the quality problems of the waterproof membrane 2 falling off, hollowing, etc. before the next construction process, and greatly avoiding the occurrence of leakage problems.

[0045] The sealing structure 3 is arranged in the wedge-shaped groove 10 to seal the waterproofing membrane 2 and the wedge-shaped groove 10 and make the surface of the wedge-shaped groove 10 flush with the surface of the parapet 1. The waterproof layer structure 4 is arranged on the surface of the parapet 1.

[0046] The sealing structure 3 in this embodiment uses sealing paste. During construction, the wedge-shaped groove 10 is filled with sealing paste to ensure that it is densely and evenly filled. The waterproof layer structure 4 is arranged on the outside of the sealing structure 3, so that the flashing end is truly "hidden", which not only more effectively avoids the occurrence of leakage problems at the coiled material end, but also ensures the overall appearance of the parapet facade.

[0047] As an optional implementation, Figure 2 Schematic diagram of the structure of the wedge-shaped groove in this embodiment. Figure 2 As shown, the wedge-shaped groove 10 is configured to include a first groove surface 101 and a second groove surface 102 arranged in parallel, and an inclined surface 103 is arranged between the first groove surface 101 and the second groove surface 102 .

[0048] The first groove surface 101 is opened on the surface of the parapet 1 ; the second groove surface 102 is arranged inside the parapet 1 ; and the cross-sectional dimension of the first groove surface 101 is greater than the cross-sectional dimension of the second groove surface 102 .

[0049] Such arrangement enables the cross-sectional dimension of the wedge-shaped groove 10 to gradually decrease from the surface to the inner side of the parapet 1, which is beneficial to the construction.

[0050] Optionally, in this embodiment, the cross-sectional dimension L1 of the first groove surface 101 is not less than 80 mm, and the cross-sectional dimension L2 of the second groove surface 102 is not less than 30 mm.

[0051] As an optional implementation, the waterproof layer structure 4 includes a mesh 41 and a waterproof mortar 42 . The mesh 41 is hung on the facade of the parapet 1 , and the waterproof mortar 42 is applied to the mesh 41 .

[0052] During construction, after the wedge-shaped groove is treated with sealing paste, the facade of the entire parapet 1 is treated with mesh hanging and waterproof mortar smearing, which not only more effectively avoids the occurrence of leakage problems at the end of the roll material, but also ensures the overall appearance of the parapet facade.

[0053] As an optional embodiment, the height dimension H between the center of the wedge-shaped groove 10 and the top of the roof structure is 500 mm.

[0054] Figure 3 It is a flow chart of the construction method of roof waterproofing structure, such as Figure 3 As shown, a construction method of the above-mentioned roof waterproof structure includes the following steps:

[0055] S1: Parapet construction, including, when installing the parapet formwork, adding a full-length horizontal wedge-shaped wooden beam on the inner side of the roof side formwork.

[0056] Among them, a wedge-shaped wooden beam is provided to facilitate the formation of the wedge-shaped groove 10. In the specific construction process, a full-length horizontal wedge-shaped wooden beam is installed at a height of 500mm from the top of the roof structure on the inner side of the roof side template to facilitate the construction operation.

[0057] S2: The parapet wall 1 is poured and demoulded. After demoulding is completed, the reserved wedge-shaped groove 10 is formed.

[0058] S3: cleaning the base layer, including cleaning the reserved wedge-shaped groove 10;

[0059] S4: Laying the waterproof membrane 2, including pressing the flashing end 20 of the waterproof membrane 2 into the wedge-shaped groove 10.

[0060] In this embodiment, when the overall waterproof membrane of the roof is constructed, the end of the flashing membrane is firmly pressed into the reserved wedge-shaped groove. Since the groove is a wedge-shaped structure, it can more effectively ensure the adhesion of the waterproof membrane 2 at the flashing end 20 and the base layer, and effectively avoid the waterproof membrane 2 from falling off, hollowing and other quality problems before the next construction process.

[0061] S5: Sealing treatment of the wedge-shaped groove 10.

[0062] In this embodiment, the wedge-shaped groove 10 is densely and evenly filled with sealing paste to ensure that the roof waterproof structure as a whole is waterproof and has a strong aesthetic appearance after the construction is completed, thereby ensuring the overall appearance of the parapet facade.

[0063] S6: Construction of parapet wall waterproofing structure.

[0064] After the wedge-shaped groove 10 is sealed, the entire parapet facade is treated with mesh and waterproof mortar. At this time, the flashing end is truly "hidden", which not only more effectively avoids the occurrence of leakage problems at the end of the roll material, but also ensures the overall appearance of the parapet facade.

[0065] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
