Description

Technical Field

[0001] This utility model belongs to the field of building waterproofing, specifically, it relates to a waterproof structure and a roof waterproofing system. Background Technology

[0002] In the field of building roof waterproofing, traditional waterproofing systems typically achieve waterproofing by laying waterproof membranes or coatings on the roof substrate. During construction, the waterproof layer extends up the parapet wall into a pre-designed groove and is mechanically anchored using metal strips and fixing nails. However, this process has significant technical flaws: during strip installation, the nail holes created by the fixing nails penetrating the waterproof layer can damage its integrity, creating through-holes for leakage. Furthermore, under temperature stress and structural deformation, stress concentration can occur around the nail holes, leading to tearing and expansion of the waterproof layer, exacerbating the risk of leakage. These defects result in existing sealing methods having high leakage risks and poor durability, increasing maintenance costs and potentially causing secondary problems such as structural corrosion due to water seepage. Utility Model Content

[0003] In view of the above-mentioned shortcomings or defects in the prior art, this utility model provides a waterproof structure and roof waterproofing system that can ensure the integrity of the waterproof layer, reduce the risk of leakage, improve the overall waterproofing effect of the waterproof layer, and at the same time reduce the later maintenance cost.

[0004] To achieve the above objectives, this utility model provides a waterproof structure, comprising:

[0005] A waterproof layer is laid on the roof and extends to the groove provided on the parapet wall facade;

[0006] The protective component includes a first plate and a second plate. The first plate is adhered to and covers the waterproof layer and is located on the lower side wall of the groove. The outer end of the first plate extends away from the bottom wall of the groove to the opening of the groove. The second plate extends downward at an angle from the outer end of the first plate away from the parapet wall.

[0007] A filler is used to fill the space between the first plate and the upper sidewall of the groove.

[0008] Optionally, the first plate and the second plate are integrally formed.

[0009] Optionally, both the first plate and the second plate are metal plates.

[0010] Optionally, an adhesive layer is provided on the inner side of the first plate, and the first plate is adhered to the waterproof layer through the adhesive layer.

[0011] Optionally, the end of the waterproof layer extends to the bottom wall of the groove, and the inner end of the first plate near the bottom wall of the groove extends to the end of the waterproof layer.

[0012] Optionally, the first plate and the second plate are connected by a circular arc transition.

[0013] Optionally, the waterproof structure further includes a sealing element that seals the outer surface of the filler facing the groove opening.

[0014] Optionally, the sealing element is a concrete layer, and the outer surface of the concrete layer is flush with the facade of the parapet wall, away from the outer surface of the filling element.

[0015] Optionally, the filler is a foam rod.

[0016] This utility model also provides a roof waterproofing system, including the above-mentioned waterproofing structure.

[0017] Through the above technical solution, in the waterproof structure of this utility model, the protective component and the filler can fix the waterproof layer, preventing the waterproof layer from aging and falling off after long-term use. At the same time, the end of the waterproof layer is completely hidden in the groove, ensuring that the end of the waterproof layer is protected from rainwater erosion. In addition, the second plate of the protective component, which extends downward at an angle away from the parapet wall, protects and drains water at the bend of the waterproof layer, preventing leakage points from forming. In this way, the integrity of the waterproof layer can be ensured, the risk of leakage can be reduced, the overall waterproof effect of the waterproof layer can be significantly improved, and the later maintenance cost can be reduced.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] A first exemplary embodiment of this utility model provides a waterproof structure, as shown in the attached figure. Figure 1 To be continued Figure 3 As shown, the waterproof structure includes:

[0036] Waterproof layer 1 is laid on the roof 6 and extends to the groove provided on the parapet wall 7 at its end;

[0037] The protective component includes a first plate 2 and a second plate 3. The first plate 2 is pasted and covers the waterproof layer 1 and is located on the lower side wall of the groove. The outer end of the first plate 2 away from the bottom wall of the groove extends to the groove opening. The second plate 3 extends downward from the outer end of the first plate 2 in a direction away from the parapet wall 7.

[0038] Filler 4 fills the space between the first plate 2 and the upper sidewall of the groove.

[0039] In the waterproof structure of this exemplary embodiment, the protective member and the filler 4 can fix the waterproof layer 1, preventing it from aging and falling off after long-term use. At the same time, the end of the waterproof layer 1 is completely hidden in the groove, ensuring that the end of the waterproof layer 1 is protected from rainwater erosion. In addition, the second plate 3, which extends downward at an angle away from the parapet wall, protects and drains water at the bend of the waterproof layer 1, preventing leakage at that point. In this way, the integrity of the waterproof layer 1 can be ensured, the risk of leakage can be reduced, the overall waterproof effect of the waterproof layer 1 can be significantly improved, and the later maintenance cost can be reduced.

[0040] Understandably, the protective component, the filler 4, and the waterproof layer 1 are fixed to each other, thereby ensuring that the end of the waterproof layer 1 can be firmly fixed in the groove.

[0041] Specifically, both the first plate 2 and the second plate 3 extend along the length of the groove to completely cover the portion of the waterproof layer 1 that bends at the lower corner of the groove, ensuring protection and fixation. Furthermore, the waterproof layer 1 is formed by laying a waterproof membrane.

[0042] In practical applications, the length of the downward-sloping extension of the second plate 3 is designed according to actual needs and application scenarios.

[0043] In an alternative embodiment, refer to the appendix Figure 3 As shown, the first plate 2 and the second plate 3 are integrally formed. This design ensures the structural stability and strength of the protective component. In practical applications, the first plate 2 and the second plate 3 can be formed by bending a single plate.

[0044] Of course, in other embodiments, the first plate 2 and the second plate 3 can be connected in other ways. For example, the first plate 2 and the second plate 3 can be fixedly connected to each other by welding.

[0045] In one optional embodiment, both the first plate 2 and the second plate 3 are metal plates. This gives the protective component good structural strength, makes it less prone to damage, has a long service life, and provides high reliability in protecting and securing the waterproof layer 1. Of course, in other embodiments, the first plate 2 and the second plate 3 can also be plates made of other materials such as plastic plates.

[0046] In an alternative embodiment, refer to the appendix Figure 3 As shown, the inner surface of the first plate 2 is provided with an adhesive layer, and the first plate 2 and the second plate 3 are adhered to the waterproof layer 1 through the adhesive layer. This arrangement effectively improves the convenience of installing the protective components.

[0047] In an alternative embodiment, refer to the appendix Figure 1 and attached Figure 2 As shown, the end of the waterproof layer 1 extends to the bottom wall of the groove, and the inner end of the first plate 2 near the bottom wall of the groove extends to the end of the waterproof layer 1. This arrangement can further improve the firmness of the waterproof layer 1.

[0048] In an alternative embodiment, refer to the appendix Figure 2 As shown, the first plate 2 and the second plate 3 are connected by a circular arc transition. This design can reduce stress concentration in the protective components, improve structural strength, and enhance assembly and usage safety.

[0049] In an alternative embodiment, refer to the appendix Figure 1 and attached Figure 2 As shown, the waterproof structure also includes a sealing element 5, which seals the outer surface of the filler 4 facing the groove opening. This arrangement ensures that the inside of the groove is filled and sealed, that is, the end of the waterproof layer 1 is buried inside the groove, thereby significantly improving the waterproof and sealing effect of the end of the waterproof layer 1.

[0050] Specifically, the sealing element 5 is a concrete layer, which is flush with the facade of the parapet wall 7, away from the outer surface of the filling element 4.

[0051] Specifically, filler 4 is a foam rod.

[0052] In practical applications, the filler 4 is first placed into the space between the first plate 2 and the upper side wall of the groove for foaming and filling, and then concrete is applied to the outer surface of the solidified filler 4 to form a concrete layer.
