Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated roof waterproofing structure, specifically a prefabricated roof waterproofing structure with a drainage channel. Background Technology

[0002] As the name suggests, the prefabricated eaves waterproofing structure with drainage channels is a type of waterproofing structure added later and used at the eaves. When rainwater falls on the roof, the waterproof layer first prevents the rainwater from penetrating to the roof panel. Then, under the action of gravity, the rainwater flows to the drainage channels at the eaves. With its unique shape and drainage slope, the drainage channels quickly collect the rainwater and guide it to the drain outlet, and then discharge it to the ground through the drainage pipe, thereby achieving the waterproofing function at the eaves and effectively protecting the eaves and surrounding structure of the building from rainwater erosion.

[0003] Existing prefabricated eaves waterproofing structures, while designed to meet drainage requirements under normal rainfall conditions, may face challenges in extreme weather events such as torrential rains or prolonged periods of continuous rainfall. If the rainfall is excessive and exceeds the drainage limit of the drainage channel, rainwater may overflow the channel, causing leaks at the eaves. Therefore, a prefabricated eaves waterproofing structure with drainage channels is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated roof waterproofing structure with a drainage channel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prefabricated waterproof roof structure with a drainage channel includes a building body and an eaves. The eaves are fixedly connected to the top of the building body, and an installation plate is fixedly connected to the front side of the building body. A drainage channel is fixedly connected to the top of the installation plate. A water-blocking groove is formed at the bottom of the eaves. A water-blocking plate is fixedly connected to the inner side of the drainage channel. Symmetrically arranged fixing blocks are fixedly connected to the inner side of the drainage channel. A sealing plate is fixedly connected to the bottom of the fixing blocks. A drainage hole is formed on the inner side of the drainage channel in front of the water-blocking plate. A water collection trough is fixedly connected to the bottom of the drainage channel below the drainage hole. A drainage plate is fixedly connected to the inner side of the water collection trough. A drainage pipe is symmetrically arranged inside the water collection trough and the drainage plate. A volute plate is fixedly connected inside the drainage pipe. A connecting plate is fixedly connected to the bottom of the installation plate. A drainage pump is symmetrically arranged at the bottom of the connecting plate. A connecting pipe is fixedly connected between the drainage pump and the drainage pipe.

[0007] Preferably, the sealing plate is located at the upper edge of the eaves, and the sealing plate and the eaves are in contact with each other.

[0008] Preferably, there are several drainage holes, which are truncated cone-shaped and evenly distributed inside the guide channel.

[0009] Preferably, the drain pump is located directly behind the drain pipe, and the drain pump is located on the left and right sides of the room.

[0010] Preferably, the guide plate is triangular in shape, with a high center and low sides, and the length and width of the guide plate match the length and width of the inner side of the water collection tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this utility model, the components such as the guide channel, water-blocking channel, water-blocking plate, fixing block, sealing plate, drainage hole, water collection channel, guide plate, drainage pipe, and volute plate effectively improve the sealing effect at the connection between the eaves and the waterproof structure. Multiple truncated cone-shaped drainage holes, utilizing the pipe shape (narrower at the top and wider at the bottom), allow the water flow to accelerate naturally under gravity. As the pipe cross-sectional area gradually increases, the constraint on the water flow during its descent decreases. According to the continuity equation, the water flow velocity increases accordingly, thereby improving the drainage speed. The triangular guide plate further guides the rainwater... The volute structure guides the water flow into the pipe, further improving the drainage efficiency. The volute structure allows the water to flow in a spiral shape, accelerating the water flow and further improving drainage efficiency. This effectively prevents rainwater from overflowing, thus solving the problem that existing prefabricated roof waterproofing structures, while designed to meet drainage needs under normal rainfall conditions, may be tested in extreme rainstorms or prolonged continuous rainfall. If the rainfall is too heavy and exceeds the drainage limit of the guide channel, rainwater may overflow the guide channel, causing leaks at the eaves.

[0013] 2. In this utility model, the water pump installed can draw water from the drain pipe through the connecting pipe in extreme weather conditions, assisting the drain pipe in draining water and discharging a portion of the water to both sides of the building, thus greatly improving the ability to resist large water flows.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A prefabricated waterproof eaves structure with a drainage channel includes a main body 1 and an eaves 2. The eaves 2 are fixedly connected to the top of the main body 1. An installation plate 3 is fixedly connected to the front side of the main body 1. A drainage channel 4 is fixedly connected to the top of the installation plate 3. A water-blocking groove 5 is formed at the bottom of the eaves 2. A water-blocking plate 6 located inside the water-blocking groove 5 is fixedly connected to the inner side of the drainage channel 4. A symmetrically arranged fixing block 7 is fixedly connected to the inner side of the drainage channel 4. A sealing plate 8 is fixedly connected to the bottom of the fixing block 7. A water-blocking plate 6 located inside the water-blocking plate 6 is formed at the bottom of the water-blocking plate 6. The bottom of the front drain hole 9 and the guide channel 4 are fixedly connected to a water collection tank 10 located below the drain hole 9. The inner side of the water collection tank 10 is fixedly connected to a guide plate 11. The water collection tank 10 and the guide plate 11 are fixedly connected to symmetrically arranged drain pipes 12. The drain pipe 12 is fixedly connected to a volute plate 13. The bottom of the mounting plate 3 is fixedly connected to a connecting plate 14. The bottom of the connecting plate 14 is fixedly connected to a symmetrically arranged drain pump 15. The drain pump 15 and the drain pipe 12 are fixedly connected to a connecting pipe 16.

[0025] The sealing plate 8 is located at the upper edge of the eaves 2. The sealing plate 8 and the eaves 2 are in close contact with each other. The sealing plate 8, which is in close contact with the upper edge of the eaves 2, can effectively improve the sealing effect at the edge. There are several drainage holes 9. The drainage holes 9 are truncated cones in shape and are evenly arranged inside the guide channel 4. The drainage efficiency can be greatly improved by setting multiple truncated cone drainage holes 9. The drainage pump 15 is located directly behind the drainage pipe 12. The drainage pump 15 is located on the left and right sides of the house body 1. It can assist the drainage pipe 12 in draining water in severe weather without affecting the normal drainage of the drainage pipe 12. The guide plate 11 is triangular in shape with a high middle and low sides. The length and width of the guide plate 11 match the length and width of the inner side of the water collection tank 10. It can comprehensively guide the rainwater in the water collection tank 10.

[0026] Workflow: When a prefabricated eaves waterproofing structure with a drainage channel is required, the entire device is powered externally. The water-blocking channel 5, water-blocking plate 6, fixing block 7, and sealing plate 8 effectively improve the sealing effect at the connection between the eaves 2 and the waterproofing structure. Multiple frustum-shaped drainage holes 9, with their narrow top and wide bottom shape, allow the water flow to accelerate naturally under gravity. As the cross-sectional area of ​​the drainage holes 9 gradually increases, the constraint on the water flow during its descent decreases. According to the continuity equation, the water flow velocity increases accordingly, thereby improving the drainage speed. Rainwater passing through the drainage holes 9 enters the water collection trough 10. Inside, the guide plate 11 accelerates the flow of rainwater in the water collection tank 10 to the drain pipe 12. The volute plate 13 further improves the drainage efficiency of the drain pipe 12. The volute structure can make the water flow into the pipe form a spiral flow, and the rotation accelerates the water flow speed, further improving the drainage efficiency and effectively preventing rainwater overflow. When the water volume is too large, the drain pump 15 can also be turned on. The drain pump 15 draws a part of the rainwater in the drain pipe 12 through the connecting pipe 16 and discharges a part of the water flow to both sides of the house body 1, which greatly improves the ability to resist large water flow, shares the drainage pressure in the drain pipe 12, and thus improves the overall drainage effect.
