Description

Technical Field

[0001] This application relates to the field of building drainage structure technology, and in particular to a high-efficiency roof drainage structure. Background Technology

[0002] The roof is the main part of the house that blocks rainwater. Most existing building roofs are made of cast concrete. After long-term exposure to wind and heat, the edges of the roof will show obvious erosion. When it rains, it becomes a collection point for rainwater, allowing rainwater to fall along the edges of the roof and form a water curtain. Even after the rain stops, the water curtain may continue for a while, easily wetting people passing by and causing discomfort to their skin. Summary of the Invention

[0003] The purpose of this application is to provide a high-efficiency roof drainage structure that can effectively reduce the occurrence of water curtains.

[0004] To achieve the above objectives, this application provides a highly efficient roof drainage structure: comprising a water-collecting board having a pair of inner inclined plates, the bottom edges of the two inner inclined plates being connected, the top edge of each inner inclined plate being connected to an outer inclined plate, the top edge of the outer inclined plate being connected to the top edge of the inner inclined plate, the bottom edge of each outer inclined plate being connected to a baffle plate, all the inclined edges of the inner and outer inclined plates in the same plane being connected to a shielding edge, each shielding edge having a central drainage hole at the connection of the two inner inclined plates, the outer side of the shielding edge being fixedly connected to a downwardly extending main drainage pipe, the main drainage pipe communicating with the central drainage hole, each shielding edge having an end drainage hole at the connection of the outer inclined plate and the baffle plate, the outer side of the shielding edge being fixedly connected to a branch drainage pipe, the branch drainage pipe communicating with the end drainage hole, thereby efficiently collecting and quickly discharging rainwater.

[0005] As a preferred embodiment, the upper surface width at the connection between the two inner inclined plates is greater than 5cm, and the upper surface width at the connection between the outer inclined plate and the baffle is greater than 5cm, to ensure that the drainage ditch structure formed between the inclined plate and the baffle can drain water smoothly.

[0006] As a preferred embodiment, the upper surface of each of the inner and outer inclined plates has a number of ribs, which are parallel to the shielding edge, thereby improving the structural strength of the inclined plates and preventing obstruction of rainwater flow.

[0007] As a preferred embodiment, several of the ribs in each group are aligned at both ends and arranged at equal intervals to ensure the uniformity of the mass distribution of the water-collecting plate and to ensure that the water-collecting plate has high structural strength throughout.

[0008] As a preferred embodiment, the shielding edge includes an inner water-blocking plate fixedly connected to the inclined side of the inner inclined plate. The inner water-blocking plate is higher than the upper surface of the inner inclined plate, thereby effectively preventing rainwater from overflowing from the inclined side of the inner inclined plate.

[0009] As a preferred embodiment, the shielding edge further includes an outer water-blocking plate fixedly connected to the inclined side of the outer inclined plate. The outer water-blocking plate is higher than the upper surface of the outer inclined plate, thereby effectively preventing rainwater from overflowing from the inclined side of the outer inclined plate.

[0010] As a preferred embodiment, the shielding edge is an integral structure, with the inner and outer water-blocking plates of the shielding edge arranged at intervals and continuously, maintaining the same cross-sectional shape as the water-gathering plate.

[0011] As a preferred embodiment, the lower end of the branch drain pipe is connected to the main drain pipe, and the main drain pipe has a collection hole. The main drain pipe is connected to the inside of the branch drain pipe through the collection hole, which can effectively reduce the length and cost of the pipeline configuration.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a water-collecting plate structure with multiple slopes and designing a structure to block rainwater from passing over the edge of the water-collecting plate, the situation of rainwater falling from the edge of the roof to form a water curtain is effectively reduced, so that people entering and leaving the house are less disturbed by rainwater.

[0014] (2) By centrally designing the drainage structure and connecting the drainage pipes, not only is the drainage efficiency improved, but the density of external pipes on the roof is also reduced, thus reducing the cost of pipe usage. Attached Figure Description

[0022] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0025] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0026] like Figure 1-6The efficient roof drainage structure shown includes a water-collecting board 4. The longitudinal section of the water-collecting board 4 in the front-to-back direction is M-shaped. The water-collecting board 4 has a pair of inner inclined plates 401. The bottom edges of the two inner inclined plates 401 are connected. The upper surface of the connection between the two inner inclined plates 401 is usually flat, forming an inverted trapezoidal drainage ditch. The bottom width generally needs to be greater than 5cm to ensure smooth drainage of rainwater. The top edge of each inner inclined plate 401 is also connected to an outer inclined plate 402. The top edge of the outer inclined plate 402 is only connected to the top edge of the inner inclined plate 401. The bottom edge of each outer inclined plate 402 is also connected to a baffle plate 403. The side of the baffle plate 403 connected to the outer inclined plate 402 is the lowest, and the side of the baffle plate 403 away from the outer inclined plate 402 is significantly higher, also forming an inverted trapezoidal drainage ditch. The upper surface width of the connection between the outer inclined plate 402 and the baffle plate 403 is greater than 5cm to ensure efficient drainage of rainwater.

[0027] Each inner inclined plate 401 and outer inclined plate 402 has several ribs 5 on its upper surface, which can effectively improve the deformation resistance of the large inner inclined plate 401 and outer inclined plate 402. The ribs 5 are parallel to the shielding edge 3, ensuring that rainwater flows down the outer surface of the inner inclined plate 401 and outer inclined plate 402 without being blocked. The ribs 5 in each group are aligned at both ends and equidistantly arranged to ensure that the mass distribution of the water collection plate 4 is relatively uniform.

[0028] All inner inclined plates 401 and outer inclined plates 402 are connected to shielding flanges 3 on their inclined sides in the same plane. There are two shielding flanges 3, which are symmetrical about the water-collecting plate 4. The shielding flange 3 includes an inner water-blocking plate 301 fixedly connected to the inclined side of the inner inclined plate 401. The inner water-blocking plate 301 is higher than the upper surface of the inner inclined plate 401 and is used to prevent water from overflowing from the inclined side of the upper surface of the inner inclined plate 401. Normally, the bottom edge of the inner water-blocking plate 301 is also lower than the lower surface of the inner inclined plate 401, thereby further improving the deformation resistance of the inclined side of the inner inclined plate 401. The shielding edge 3 also includes an outer water-blocking plate 302 fixedly connected to the inclined side of the outer inclined plate 402. The outer water-blocking plate 302 is higher than the upper surface of the outer inclined plate 402 and is used to prevent water from overflowing from the inclined side of the upper surface of the outer inclined plate 402. Normally, the bottom edge of the outer water-blocking plate 302 is also lower than the lower surface of the outer inclined plate 402, which further improves the deformation resistance of the inclined side of the outer inclined plate 402. The shielding edge 3 is an integral structure. The inner water-blocking plate 301 and the outer water-blocking plate 302 of the shielding edge 3 are arranged at intervals and continuously to form an M-shape with the same cross-section as the water-collecting plate 4.

[0029] Each shielding edge 3 has a central drainage hole 303 at the connection of the two inner inclined plates 401. A main drainage pipe 1 extending downward is fixedly connected to the outer side of the shielding edge 3. The main drainage pipe 1 is connected to the central drainage hole 303. Each shielding edge 3 has an end drainage hole 304 at the connection of the outer inclined plate 402 and the baffle plate 403. A branch drainage pipe 2 is also fixedly connected to the outer side of the shielding edge 3. The branch drainage pipe 2 is connected to the end drainage hole 304, and the lower end of the branch drainage pipe 2 is connected to the main drainage pipe 1. The main drainage pipe 1 has a collection hole 101. The main drainage pipe 1 is connected to the branch drainage pipe 2 through the collection hole 101. This can effectively reduce the density of pipes on the outer side of the building and reduce the cost of pipe configuration.

[0030] Working principle: This roof drainage structure needs to be installed on the top of the building. When rainwater falls, it will first fall on the water collection plate 4. The edge of the water collection plate 4 has a thin shielding edge 3 and a baffle plate 403. It is difficult for rainwater to drip over the shielding edge 3 and the baffle plate 403 from the edge of the water collection plate 4. Almost all the rainwater in contact with this drainage structure will either fall on the inner inclined plate 401 and be collected in the drainage ditch formed between the lower edges of the inner inclined plate 401, and then enter the main drainage pipe 1 from the central drainage hole 303 and be discharged downward; or fall on the outer inclined plate 402 and be collected in the drainage ditch formed between the lower edges of the outer inclined plate 402 and the baffle plate 403, and then enter the branch drainage pipe 2 from the end drainage hole 304, and finally flow back into the main drainage pipe 1 to form a backflow and be discharged downward.
