Description

Technical Field

[0001] This application relates to the field of building roof panel technology, and in particular to a cross-roof waterproofing structure. Background Technology

[0002] In building roof design, the intersections of two sloping roof panels (such as ridges and gutters) are prone to leakage due to their complex structure and numerous joints, caused by thermal expansion and contraction, rainwater erosion, or construction errors. Traditional solutions typically involve simple sealant filling: this method is prone to aging and cracking after long-term use, resulting in poor waterproofing.

[0003] Metal flashing: relies on welding or riveting, which is complicated to construct, and the metal and the roof panel have different expansion coefficients, making them prone to deformation and water seepage.

[0004] Ordinary drainage channel design: can only divert surface rainwater, and cannot solve the problem of capillary seepage at the joints.

[0005] Therefore, there is an urgent need for a simple, well-sealed, and durable solution for preventing leakage in cross-roof structures. Utility Model Content

[0006] Therefore, it is necessary to provide a cross-roof waterproofing structure, the specific technical solution of which is as follows.

[0007] A cross-roof waterproofing structure includes a first sloping roof panel and a second sloping roof panel. Below the first and second sloping roof panels are an insulation layer, a leveling plate, a waterproof layer, and a noise reduction layer. The bottoms of the first and second sloping roof panels intersect. A connecting member is provided at the bottom of the first and second sloping roof panels. Slots are provided on both sides of the connecting member, allowing the bottoms of the first and second sloping roof panels to be inserted into the slots. A U-shaped rubber seal is provided within the slots to enclose the bottoms of the first and second sloping roof panels. Locking structures are provided between the connecting member and the first and second sloping roof panels on both sides. A leak-proof drainage groove is provided below the connecting member, with the tops of the groove walls on both sides abutting against the bottom surfaces of the first and second sloping roof panels.

[0008] Furthermore, the locking structure is a rivet structure, which passes through the mating member, the first sloping roof panel, and the second sloping roof panel.

[0009] Furthermore, the top of the docking component is provided with an arc-shaped concave surface, and the bottom of the docking component is provided with an arc-shaped convex surface.

[0010] Furthermore, the leak-proof drainage groove is provided with a positioning groove, and the bottom surface of the docking part is provided with a positioning insert plate, which can be adapted to the positioning groove.

[0011] Furthermore, the outer walls on both sides of the leak-proof drainage channel are provided with water-proof grooves, and the bottom surfaces of the first and second sloping roof panels are provided with sealing gaskets, the two sides of which can abut against the top surface of the water-proof channel.

[0012] Furthermore, the sealing gasket is a T-shaped rubber component, and the protruding part in the middle of the T-shaped rubber component can be inserted into the water-proof groove.

[0013] Furthermore, the water-blocking tank is filled with dried alumina particles.

[0014] Furthermore, the water-blocking trough has drainage holes on its walls.

[0015] Compared with existing technologies, this utility model has the following beneficial effects:

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Reference Figures 1-4 As shown, this embodiment provides a cross-roof waterproofing structure, including a first sloping roof panel 1 and a second sloping roof panel 2. Below the first sloping roof panel 1 and the second sloping roof panel 2 are provided an insulation layer, a leveling plate, a waterproof layer, and a noise reduction layer. The bottoms of the first sloping roof panel 1 and the second sloping roof panel 2 intersect. A connecting piece 3 is provided at the bottom of the first sloping roof panel 1 and the second sloping roof panel 2. Slots 4 are provided on both sides of the connecting piece 3, allowing the bottoms of the first sloping roof panel 1 and the second sloping roof panel 2 to be inserted into the slots 4. A U-shaped rubber seal 5 is provided in the slots 4 to enclose the bottoms of the first sloping roof panel 1 and the second sloping roof panel 2. A locking structure 6 is provided between the two sides of the connecting piece 3 and the first sloping roof panel 1 and the second sloping roof panel 2. A leak-proof drainage groove 7 is provided below the connecting piece 3, and the tops of the groove walls on both sides of the leak-proof drainage groove 7 can abut against the bottom surfaces of the first sloping roof panel 1 and the second sloping roof panel 2.

[0026] In the cross-roof waterproofing structure of this utility model, a connecting piece 3 is provided to connect the bottom of the first sloping roof panel 1 and the second sloping roof panel 2. It is sealed by a U-shaped rubber seal 5, which also has the function of coping with thermal expansion and contraction deformation. It is then locked by a locking structure 6, resulting in good sealing effect, firm connection, and good waterproof performance.

[0027] Furthermore, a leak-proof drainage channel 7 is installed below the connecting piece 3 for drainage. When leakage occurs at the connection between the connecting piece 3 and the first sloping roof panel 1 and the second sloping roof panel 2, rainwater will seep into the leak-proof drainage channel 7 and be discharged through the leak-proof drainage channel 7. It will not seep into the sound insulation and heat insulation layer below the first sloping roof panel 1 and the second sloping roof panel 2, thus avoiding wetting the structure below the first sloping roof panel 1 and the second sloping roof panel 2. This effectively prevents water accumulation in the structure below the first sloping roof panel 1 and the second sloping roof panel 2, ensuring that the roof will not leak.

[0028] Specifically, refer to Figure 1 and Figure 3The locking structure 6 is a rivet structure. The rivet structure passes through the connecting piece 3, the first sloping roof panel 1, and the second sloping roof panel 2. The rivet structure can tightly lock the connecting piece 3, the first sloping roof panel 1, and the second sloping roof panel 2, making them difficult to loosen. A rubber gasket is placed between the rivet structure and the top surface of the first sloping roof panel 1 and the second sloping roof panel 2 for waterproofing and to prevent leakage.

[0029] Specifically, refer to Figure 4 The top of the docking component 3 is provided with an arc-shaped concave surface 8, and the bottom of the docking component 3 is provided with an arc-shaped convex surface 9. The arc-shaped concave surface 8 facilitates the flow of water and prevents water accumulation on the docking component 3.

[0030] Specifically, refer to Figure 3 The anti-leakage drainage channel 7 is provided with a positioning groove 10, and the bottom surface of the docking part 3 is provided with a positioning insert plate 11. The positioning insert plate 11 can be adapted to the positioning groove 10. The setting of the positioning groove 10 facilitates the docking part 3 to be positioned by cooperating with the positioning insert plate 11 and the positioning groove 10, which helps to improve assembly efficiency, reduce assembly difficulty, and make the installation of the roof panel more convenient, faster, and simpler.

[0031] Specifically, refer to Figure 3 The outer walls on both sides of the anti-leakage drainage channel 7 are provided with water-proof channels 12, and the bottom surfaces of the first sloping roof panel 1 and the second sloping roof panel 2 are provided with sealing gaskets 13. The two sides of the sealing gaskets 13 can abut against the top surface of the water-proof channel 12. In this embodiment, the sealing gaskets 13 on the bottom surfaces of the first sloping roof panel 1 and the second sloping roof panel 2 abut against the top surface of the water-proof channel 12, which plays a role in sealing and waterproofing, preventing rainwater from seeping through the gaps into the structure below the roof panel.

[0032] Specifically, refer to Figure 3 The sealing gasket 13 is a T-shaped rubber component. The protruding part in the middle of the T-shaped rubber component can be inserted into the water-proof groove 12. The protruding part of the T-shaped rubber component can be inserted into the water-proof groove 12, forming a meandering water-proof channel, which effectively prevents rainwater from leaking out.

[0033] Specifically, refer to Figure 3The water-proof trough 12 is filled with alumina dry particles. The wall of the water-proof trough 12 is provided with drainage holes that communicate with the leak-proof drainage trough 7. The alumina dry particles play a role in absorbing water. When water vapor leaks into the water-proof trough 12, the alumina dry particles can absorb the water vapor, preventing the water vapor from entering below the first sloping roof panel 1 and the second sloping roof panel 2, and also preventing the sound insulation cotton structure below the first sloping roof panel 1 and the second sloping roof panel 2 from getting damp and moldy. The wall of the water-proof trough 12 is provided with drainage holes or vent holes. When the sun is shining, the water vapor absorbed by the alumina dry particles will flow from the drainage holes or vent holes into the leak-proof drainage trough 7 and be discharged through the leak-proof drainage trough 7.

[0034] Specifically, refer to Figure 3 The bottom of the anti-leakage drainage channel 7 is a V-shaped channel structure. The anti-leakage drainage channel 7 is stamped from a deformable thin steel sheet. That is, the V-shaped channel structure can be appropriately opened outward or narrowed inward. The slope of the channel wall of the V-shaped channel structure can be appropriately changed according to the inclination angle of the first sloping roof panel 1 and the second sloping roof panel 2.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above embodiments only illustrate one or more implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
