Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, specifically to a building roof waterproofing structure. Background Technology

[0002] The roof is the uppermost covering structure of a building, serving as both a load-bearing structure and providing horizontal support for the upper part of the building. Under rainy or snowy conditions, a large amount of water can accumulate on the roof. To ensure that this water does not seep into the building and cause leaks, waterproof membrane is typically laid on the roof to form a waterproof layer, effectively preventing external moisture from entering or internal moisture from leaking in.

[0003] However, there are shortcomings in the installation of waterproof membrane. When laying waterproof membrane at the inside corner of the roof, the membrane needs to be cut and re-spliced, and an extra layer of waterproof membrane or sealant should be laid at the joint to achieve a seal and waterproofing. The joint is more susceptible to the impact of rain and snow, and is prone to water seepage after long-term use.

[0004] Therefore, this utility model provides a waterproof structure for the joint of waterproof membrane for building roofs to enhance the sealing and waterproofing effect of the joint, thereby making the roof waterproofing effect better. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that the joints of waterproof membranes are easily affected by external rain and snow, leading to water seepage after long-term use.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a waterproof structure for building roofs, including sealing elements;

[0009] The sealing element is a cuboid structure. One corner of the sealing element is in contact with the inside corner of the roof, and the opposite vertical corner is a rounded structure. The corner of the sealing element in contact with the roof has a notch with a fan-shaped cross-section and the lower end extends out of the sealing element. The upper end of the sealing element has a through hole communicating with the notch. Sealing adhesive is poured into the through hole to seal the inside corner.

[0010] A sealing frame is fitted on the upper outer side of the sealing element. A T-shaped hole is provided above the end of the sealing frame that is in contact with the edge of the roof. A bolt is inserted into the T-shaped hole to fix the position of the sealing element.

[0011] The upper end of the sealing element is fitted with a rubber cap, the length and width of which are greater than the length and width of the sealing frame, to prevent rain and snow from seeping into the sealing element from above.

[0012] As an improvement, the lower end of the seal is provided with a groove, which extends out from both ends of the seal that are in contact with the inside corner of the roof.

[0013] As an improvement, the upper surface of the sealing frame is inclined from the center to the edge, and the bolt is located in the T-shaped hole.

[0014] As an improvement, the inner wall of the sealing frame is provided with a rubber pad layer.

[0015] As an improvement, the upper side wall of the seal is provided with an annular groove, and the inner wall of the rubber cover is provided with a rubber ring that mates with the annular groove.

[0016] As an improvement, a transparent plastic frame is fitted onto the outer wall of the rubber cover, with the lower end of the plastic frame located below the upper end of the sealing frame.

[0017] III. Beneficial Effects

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] This utility model uses a sealing element that adheres to the roof's internal corner. The corner has a fan-shaped notch and through-hole for easy injection of sealant, achieving seamless filling of the roof's internal corner. This design avoids the weak points of traditional rolled material cutting and splicing, directly injecting adhesive into key gaps to form a continuous waterproof layer, effectively preventing rain and snow penetration. Secondly, the fitting design of the sealing frame and the sealing element, combined with T-shaped holes and bolts, enables the installation and secure fixing of the sealing element. Furthermore, the upper surface of the sealing frame slopes towards the edge, facilitating rapid drainage of rainwater and preventing water accumulation and penetration. The rubber pad layer on its inner wall further maintains the sealing effect. Moreover, the rubber cover and the sealing element use a nested design of annular grooves and rubber rings, forming a double barrier with the sealing frame to prevent rain and snow from seeping in from top to bottom. The transparent plastic frame fitted onto the outer wall provides additional waterproofing and visual monitoring. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] As attached Figures 1-4 As shown, the building roof waterproofing structure includes a sealant 1, which is a cuboid structure. One corner of the sealant 1 is attached to the roof's internal corner, and the opposite vertical corner is rounded. The corner where the sealant 1 is attached to the roof has a notch 2, which has a fan-shaped cross-section and extends out of the sealant 1 at the bottom. The upper end of the sealant 1 has a through hole 3 that communicates with the notch 2, so that the sealant 1 is attached to the roof's internal corner. Sealing adhesive can be injected through the through hole 3 to seal the internal corner, achieving seamless filling of the roof's internal corner. This design avoids the weak links of traditional roll material cutting and splicing, and directly injects adhesive into key gaps to form a continuous waterproof layer, effectively preventing rain and snow penetration.

[0027] Furthermore, the lower end of the sealing element 1 is provided with a groove 8, which extends out of the two ends of the sealing element 1 that are in contact with the roof corner, so that more adhesive is injected into the roof floor and prevents rain and snow from seeping in from the lower end.

[0028] A sealing frame 4 is fitted on the outer side of the upper part of the sealing element 1. A T-shaped hole 5 is provided above the end of the sealing frame 4 that is in contact with the edge of the roof. A bolt 6 is inserted into the T-shaped hole 5 to fix the position of the sealing element 1.

[0029] Furthermore, the upper surface of the sealing frame 4 is inclined from the center to the edge to facilitate the rapid drainage of rainwater and prevent water from accumulating and seeping into the bolt 6 located in the T-shaped hole 5. The inner wall of the sealing frame 4 is provided with a rubber pad layer to further maintain the sealing effect.

[0030] The upper end of the sealing element 1 is fitted with a rubber cap 7. The upper side wall of the sealing element 1 is provided with an annular groove 9. The inner wall of the rubber cap 7 is provided with a rubber ring 10 that matches the annular groove 9, so that the rubber cap 7 is fitted and fixed on the upper part of the sealing element 1. The length and width of the rubber cap 7 are greater than the length and width of the sealing frame 4, forming a double barrier with the sealing frame 4 to prevent rain and snow from seeping into the sealing element 1 from top to bottom.

[0031] Furthermore, the outer wall of the rubber cover 7 is fitted with a transparent plastic frame 11, the lower end of which is located below the upper end of the sealing frame 4, providing additional waterproofing and visual monitoring.
