Description

Technical Field

[0001] This application relates to the field of building drainage, and in particular to a building roof drainage structure and its construction method. Background Technology

[0002] A pitched roof is a type of roof characterized by a large slope (usually exceeding 10%), which has excellent drainage performance and can reduce the cost of waterproofing construction through self-drainage.

[0003] The sloping roof design allows rainwater and snow to slide off quickly, and combined with gutters and a waterproof layer, it results in a low annual leakage rate and high tolerance to extreme weather. However, in actual use, the sloping roof structure causes a large amount of liquid to accumulate and drip, affecting pedestrian passage under the eaves and causing inconvenience, which needs to be improved. Summary of the Invention

[0004] To reduce the accumulation and dripping of liquid along a sloping roof, this application provides a roof drainage structure and its construction method.

[0005] This application provides a roof drainage structure for a building, which adopts the following technical solution:

[0006] A roof drainage structure for a building includes a roof body with a sloping roof section and a water collection section on the side wall of the roof body. The sloping roof section extends downward along the center line of the roof body towards the water collection section. The water collection section has a water collection trough located on the side of the water collection section away from the ground. The water collection trough allows rainwater from the sloping roof section to flow into it. The water collection section has a drain pipe connected to the water collection trough.

[0007] By adopting the above technical solution and setting up a water collection section, the liquid flowing down from the sloping roof can be collected, which facilitates stable drainage and can also be used to collect liquid, reducing its impact on people entering and exiting under the eaves. In the face of extreme weather, it reduces the possibility of roof tiles falling off, thus improving overall safety.

[0008] Optionally, the water collection section is equipped with a drain box located at one end of the water collection section near the sloping roof. The drain box has a drain hole on its side wall, which is used to connect to a drain pipe. The drain box has a mounting groove located at the top of the drain box. The mounting groove has a return spring. The end of the return spring away from the bottom of the mounting groove has a drain section. The drain section has a receiving groove for liquid to flow into. The receiving groove has a connecting hole in its wall, which is used to drain liquid from the receiving groove. The drain section is connected to a sliding plate with a sliding hole. The drain box has an auxiliary hole that connects to the sliding hole. When the drain section moves towards the bottom of the mounting groove, the auxiliary hole connects to the sliding hole.

[0009] By adopting the above technical solution and setting up a drainage section, when the drainage rate of the sloping roof is too fast, some liquid flows into the drainage section. When the liquid inflow rate of the receiving tank is greater than the liquid outflow rate, the drainage section moves towards the bottom of the installation tank and the return spring is in a compressed state. At this time, the auxiliary hole gradually connects to the sliding hole, thereby improving the overall drainage effect and reducing the situation of excessive water accumulation in the water collection section and poor drainage.

[0010] Optionally, the auxiliary hole includes a first drainage hole and a second drainage hole. The drainage box is provided with a cut-off groove. The sliding plate slides in the cut-off groove. The cut-off groove is located between the first drainage hole and the second drainage hole. The axial direction of the first drainage hole is consistent with the axial direction of the second drainage hole. The sliding hole is used to connect the first drainage hole and the second drainage hole.

[0011] By adopting the above technical solution, drainage hole one and drainage hole two are set up. The sliding hole connects drainage hole one and drainage hole two to assist drainage during heavy rain, thereby improving the overall drainage effect. Since the sliding hole connects drainage hole one and drainage hole two, the drainage hole has been draining for a certain period of time. Therefore, gravel and impurities are discharged through the drainage hole, thereby reducing the possibility of them entering drainage hole one, the cut-off groove and drainage hole two, thus facilitating the sliding of the sliding plate.

[0012] Optionally, the mounting groove wall is provided with a guide protrusion, the guide protrusion extends in a vertical direction, and the drainage part is provided with a guide groove for the guide protrusion to be embedded in.

[0013] By adopting the above technical solution, a guide ridge and a guide groove are set. The guide ridge guides the movement of the drainage part, reducing the shaking of the drainage part during movement caused by the return spring support.

[0014] Secondly, this application provides a construction method for a building roof drainage structure, which adopts the following technical solution: including the above-mentioned building roof drainage structure, and further including the following steps:

[0015] S1: Roof sidewall treatment: The roof sidewall is reserved with a groove for embedding the water collection part;

[0016] S2: Structure construction: Embed the water collection part into the reserved groove and temporarily fix it;

[0017] S3: Casting: The water collection part is fixed by the template. The water collection part is provided with a casting groove in the horizontal direction. The casting groove runs through the water collection part. The template closes the groove opening on one side of the casting groove, and the groove opening on the other side is used for casting.

[0018] S4: Casting is carried out through a casting trough, and temporary fixation and formwork are removed after casting is completed;

[0019] S5: Strength test: A load-bearing test is conducted on the side of the water collection section away from the roof sidewall to test the structural strength;

[0020] S6: Leave a cut-off groove in the water collection section and install the drainage box.

[0021] By adopting the above technical solution, the water collection part is a prefabricated component, which is connected and fixed to the roof by pouring water into the casting tank, thereby facilitating the installation of the components.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. A water collection section is installed to collect liquid flowing down from the sloping roof, which facilitates stable drainage and can also be used to collect liquid, reducing its impact on people entering and exiting under the eaves. In the face of extreme weather, it reduces the possibility of roof tiles falling off, thus improving overall safety.

[0024] 2. A drainage section is installed. When the drainage rate of the sloping roof is too fast, some liquid flows into the drainage section. When the liquid inflow rate of the receiving tank is greater than the liquid outflow rate, the drainage section moves towards the bottom of the installation tank and compresses the return spring. At this time, the auxiliary hole gradually connects to the sliding hole, thereby improving the overall drainage effect and reducing the situation of excessive water accumulation in the water collection section and poor drainage.

[0025] 3. A guide ridge and guide groove are provided. The guide ridge guides the movement of the drainage section, reducing the shaking of the drainage section during movement caused by the return spring support. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses a roof drainage structure for buildings. (Refer to...) Figure 1 It includes a roof body 1 and a water collection part 2. The side wall of the roof body 1 is provided with a reserved groove 3. The water collection part 2 is embedded in the reserved groove 3. The roof body 1 is provided with a sloping roof part 4. The sloping roof part 4 extends downward along the center line of the roof body 1 toward the water collection part 2.

[0034] The water collection section 2 is provided with a casting groove 5, which is located on the side of the water collection section 2 near the bottom of the reserved groove 3. The casting groove 5 penetrates the water collection section 2, and the penetration direction of the casting groove 5 is horizontal. When the water collection section 2 is embedded in the reserved groove 3, the opening of the casting groove 5 faces the bottom of the reserved groove 3, and there is a gap between the opening of the casting groove 5 and the bottom of the reserved groove 3.

[0035] The water collection section 2 is provided with a water collection trough 6, which is located on the side of the water collection section 2 away from the ground. The water collection trough 6 is used to allow rainwater from the sloping roof section 4 to flow in. The water collection section 2 is provided with a drain pipe 7, which is connected to the water collection trough 6. The drain pipe 7 is used to collect and discharge the liquid from the water collection trough 6.

[0036] The water collection section 2 is equipped with a drain box 8, located at one end of the water collection section 2 near the sloping roof section 4. The drain box 8 has a drain hole 20 and an auxiliary hole 9 on its side wall, both of which are connected to a drain pipe 7. The drain box 8 has a mounting groove 10 located at its top. A return spring 11 is located at the bottom of the mounting groove 10, and a drain section 12 is located at the end of the return spring 11 furthest from the bottom of the mounting groove 10. The mounting groove 10 has a guide protrusion 13 on its wall, extending vertically. The drain section 12 has a guide groove 14 into which the guide protrusion 13 is inserted. The drain section 12 slides along the guide protrusion 13 via the guide groove 14, with the sliding direction of the drain section 12 being the extension direction of the guide protrusion 13.

[0037] The drainage section 12 is connected to a sliding plate 15, which has a sliding hole 16 located on its side wall. The auxiliary hole 9 includes a first drainage hole 91 and a second drainage hole 92, with the axial direction of the first drainage hole 91 aligned with that of the second drainage hole 92. The drainage box 8 has a cut-off groove 17 located between the first drainage hole 91 and the second drainage hole 92. The sliding plate 15 slides along the wall of the cut-off groove 17, and the sliding hole 16 connects the first drainage hole 91 and the second drainage hole 92. In this application, the cut-off groove 17 extends to the water collection section 2. When the drainage section 12 is in its initial position, the sliding plate 15 is embedded in the cut-off groove 17 on one side of the water collection section 2.

[0038] When the drainage section 12 moves toward the bottom of the mounting groove 10, the sliding hole 16 connects the first drainage hole 91 and the second drainage hole 92. In this application, the dimensions of the first drainage hole 91 and the second drainage hole 92 are smaller than the dimensions of the drainage hole 20.

[0039] The drainage section 12 is provided with a receiving groove 18, which is located on the side of the drainage section 12 away from the return spring 11. The receiving groove 18 is for liquid to flow in, and the groove wall of the receiving groove 18 is provided with a connecting hole 19 for discharging liquid from the receiving groove.

[0040] The implementation principle of a roof drainage structure in this application embodiment is as follows: In actual use, liquid moves along the sloping roof 4 to the water collection tank 6 and the receiving tank 18. Liquid in the water collection tank 6 enters the drain pipe 7 through the drain hole 20, and liquid in the receiving tank 18 is discharged through the connecting hole 19 and enters the drain pipe 7 through the drain hole 20. When the rainfall increases, the liquid discharge rate of the receiving tank 18 is less than the liquid entry rate. At this time, the drainage section 12 moves downward and drives the sliding plate 15 to move. When the sliding plate 15 moves to connect with the auxiliary hole 9, the liquid enters the drain pipe 7 through the auxiliary hole 9, thereby improving the drainage efficiency.
