Description

A leak-proof roof structure Technical Field

[0001] This application relates to the field of building roofing panel technology, and in particular to a leak-proof roofing structure. Background Technology

[0002] Roof structures typically include a joist, vapor barrier, insulation layer, load-bearing slab, leveling slab, waterproofing layer, noise reduction layer, and roof panels. In traditional roof structures, the joints between roof panels are high-risk areas for leakage. Current technology usually treats these joints with sealant or simple overlapping. However, the sealant applied at the joints between roof panels is prone to aging and cracking, leading to waterproofing failure. During heavy rainstorms, excessive water accumulation on the roof panels can soak the joints, allowing rainwater to seep into the rock wool structure beneath the roof panels. This increased weight after absorbing water can easily trigger a roof panel collapse.

[0003] Therefore, there is an urgent need for a roof structure that can effectively drain water when there is leakage at the roof panel connection joints and can effectively prevent the structure below the roof panel from getting wet. Summary of the Invention

[0004] Therefore, it is necessary to provide a leak-proof roof structure, the specific technical solution of which is as follows.

[0005] A leak-proof roof structure includes a keel, a load-bearing plate, a leveling plate, a waterproof layer, a noise reduction layer, and a roof panel. The leveling plate has multiple support plates arranged in an array vertically. The roof panel has hook structures on both sides that connect to the support plates. The bottom of the multiple support plates arranged longitudinally has a common water collection groove. The bottom of the water collection groove has a protrusion. The protrusion has a through hole for the support plates to pass through. The support plates and the protrusion are all fitted with a rubber sealing sleeve.

[0006] Furthermore, the rubber sealing sleeve is provided with a stepped hole structure. The upper part of the stepped hole structure is provided with a first positioning hole that is adapted to the surface of the support plate. The upper part is provided with a second positioning hole that is adapted to the surface of the boss. A positioning surface adapted to the top surface of the boss is provided between the bottom end of the first positioning hole and the top end of the second positioning hole. A chamfer structure is provided at the connection between the bottom end of the first positioning hole and the positioning surface. A sealing gasket is provided at the chamfer structure.

[0007] Furthermore, the outer wall of the rubber sealing sleeve is provided with a locking screw that is threadedly connected to the boss.

[0008] Furthermore, the top of the outer wall of the rubber sealing sleeve is narrowed and provided with a guide slope.

[0009] Furthermore, the two side walls of the water receiving trough are provided with inclined baffles corresponding to the protrusions, and the top of the inclined baffles can abut against the bottom surface of the roof panel.

[0010] Furthermore, the bottom end of the inclined baffle is provided with a vertical plate that is connected to the wall of the water receiving trough by a bolt structure.

[0011] Furthermore, the inclined baffle is a rubber plate structure capable of elastic deformation.

[0012] Furthermore, the load-bearing plate, leveling plate, waterproof layer, noise reduction layer and roof panel are arranged sequentially from bottom to top. The waterproof layer and noise reduction layer are provided with perforations for the support plate to pass through, and the noise reduction layer is provided with a clearance groove that adapts to the outer wall of the water receiving trough.

[0013] Compared with existing technologies, this utility model has the following beneficial effects:

[0014] The waterproof roof structure of this utility model has a water collection groove set below the connection node of the roof panel, which can collect water and drain the rainwater that enters under the roof panel, preventing the noise reduction layer and other structures from being soaked by water accumulation; the rubber sealing sleeve achieves double sealing at the connection between the support panel and the boss through the stepped hole structure and the sealing gasket, and the inclined baffle forms a third waterproof barrier, completely blocking the leakage path.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Referring to Figures 1-4, this embodiment provides a leak-proof roof structure, including a keel 1, a vapor barrier 22, an insulation layer 23, a load-bearing plate 2, a leveling plate 3, a waterproof layer 4, a noise reduction layer 5, and a roof panel 6. The leveling plate 3 is vertically provided with multiple arrayed support plates 7. The roof panel 6 has hook structures 8 on both sides that connect to the support plates 7. The bottom of the multiple longitudinally arranged support plates 7 is provided with a water collection groove 9. The water collection groove 9 extends along the length of the roof panel 6. The bottom of the water collection groove 9 is provided with a boss 10. The boss 10 has a through hole 11 for the support plates 7 to pass through. The support plates 7 and the boss 10 are all fitted with a rubber sealing sleeve 12.

[0029] In the waterproof roof structure of this utility model, the roof panels 6 are connected to each other on the support panel 7 by the hook structure 8, which can prevent rainwater from easily seeping in from the connection node.

[0030] Moreover, a water collection trough 9 is installed below the connection node. Rainwater seeping in from the connection node enters the water collection trough 9 and then flows down along the water collection trough 9 to the bottom and is discharged from the bottom of the water collection trough 9. This prevents the noise reduction layer 5 under the roof panel 6 from being soaked and further prevents leakage in the roof structure.

[0031] A rubber sealing sleeve 12 is fitted around the support plate 7 and the boss 10. The inner wall of the rubber sealing sleeve 12 can be in close contact with the outer wall of the support plate 7 and the boss 10, effectively preventing rainwater from leaking downward from the gap between the support plate 7 and the sleeve hole 11 of the boss 10.

[0032] Specifically, referring to Figure 3, the rubber sealing sleeve 12 has a stepped hole structure. The upper part of the stepped hole structure has a first positioning hole 13 adapted to the surface of the support plate 7, and the upper part has a second positioning hole 14 adapted to the surface of the boss 10. A positioning surface adapted to the top surface of the boss 10 is provided between the bottom end of the first positioning hole 13 and the top end of the second positioning hole 14. A chamfer structure 15 is provided at the connection between the bottom end of the first positioning hole 13 and the positioning surface, and a sealing gasket 16 is provided at the chamfer structure 15. The sealing gasket 16 can make tight contact with the top surfaces of the support plate 7 and the boss 10, effectively preventing leakage.

[0033] In this embodiment, the outer wall of the rubber sealing sleeve 12 is provided with a locking screw that is threadedly connected to the boss 10. The locking screw can securely lock the rubber sealing sleeve 12 and the boss 10 to prevent relative vertical movement and to prevent rainwater from leaking into the noise reduction layer 5 through the gap between the sleeve hole 11 of the boss 10 and the support plate 7 after the rubber sealing sleeve 12 and the boss 10 separate.

[0034] Specifically, referring to Figure 3, the top of the outer wall of the rubber sealing sleeve 12 is narrowed and provided with a guide slope 18, so that rainwater can flow into the water receiving groove 9 under the guidance of the guide slope 18, preventing rainwater from leaking out from the gap between the rubber sealing sleeve 12 and the support plate 7.

[0035] Specifically, referring to Figure 2, the two side walls of the water receiving trough 9 are provided with inclined baffles 19 corresponding to the protrusions 10. The inclined baffles 19 have the function of blocking water, allowing rainwater leaking from the connection node to enter the water receiving trough 9. The top of the inclined baffles 19 can abut against the bottom surface of the roof panel 6. The top of the inclined baffles 19 is provided with a sealing strip that abuts against the bottom surface of the roof panel 6 to further prevent rainwater leakage.

[0036] In this embodiment, the bottom end of the inclined baffle 19 is provided with a vertical plate 20 that is connected to the wall of the water receiving trough 9 by bolts. The inclined baffle 19 is quickly connected to the wall of the water receiving trough 9 through the vertical plate 20, making installation convenient and quick.

[0037] In this embodiment, the inclined baffle 19 is a rubber sheet structure capable of elastic deformation. The rubber sheet structure can adapt to the shape changes of the roof panel 6 and has good adaptability.

[0038] In this embodiment, the load-bearing plate 2, leveling plate 3, waterproof layer 4, noise reduction layer 5 and roof panel 6 are arranged sequentially from bottom to top. The waterproof layer 4 and noise reduction layer 5 are provided with perforations for the support plate 7 to pass through. The noise reduction layer 5 is provided with a relief groove 21 that adapts to the outer wall of the water receiving groove 9. The water receiving groove 9 is positioned and installed in the relief groove 21, and will not easily move laterally.

[0039] 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.

[0040] 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.
