Technical Field

[0001] The invention relates to the technical field of rainwater overflow auxiliary equipment for building facades, and in particular to a rainwater overflow outlet device for building facades. Background Art

[0002] With the progress of society, modern building facades usually use light, transparent and weather-resistant modern materials, such as glass, steel, etc. Modern building facades focus on simplicity, geometry and symmetry. Through technological innovation, irregular-shaped facades are often designed to increase the dynamic and uniqueness of the facade, such as curved curtain walls and vertical curtain walls. The facade is a vertical surface or an upper curved surface.

[0003] In view of this, in order not to affect the building's facade effect, the roof overflow method is to set up a separate overflow pipe in the building, and the overflow pipe is connected to the rainwater pipe network. However, this design is difficult to construct, and has a high construction period and cost.

[0004] The roof rainwater system refers to a series of structures and equipment that drains rainwater from the roof to avoid water accumulation and prevent damage to the building. The installation of roof rainwater overflow facilities is of great significance to the structural safety of the building and the safety and reliability of the rainwater drainage system.

[0005] At present, there are two common overflow methods for roof overflow: 1. Setting overflow ports on the outer wall for scattered drainage; 2. Discharging rainwater in an organized manner inside the building through rainwater gullies and pipes. The first overflow method will affect the appearance of the facade; the second overflow method will increase the number of pipes, occupy the effective use space in the pipe well, increase the difficulty of comprehensive ceiling layout, and increase the cost of construction projects. Summary of the invention

[0006] In order to solve the existing technical problems in the above-mentioned background technology, the present invention provides a rainwater overflow outlet device for a building facade.

A method for overflowing a rainwater overflow outlet device on a building facade, comprising the following steps: Step A: Conduct on-site survey and make appropriate overflow devices according to the building facade curtain wall design; Step B: Connect the rainwater pipe to the groove interface, and connect the rainwater pipe to the overflow device; Step C: When it rains, adaptive discharge is performed based on the amount of rainwater on the roof.

[0014] Preferably, in step C, when the amount of rainwater on the roof is small, the impact force of the rainwater is small, and the rainwater is discharged directly from the reserved gap between the water discharge baffle and the transition receiving member through the overflow device; When the amount of rainwater increases, the drainage capacity of the reserved gap is insufficient, and the rainwater impacts the drainage baffle under the action of gravity, pushing the drainage baffle open, and the rainwater is discharged quickly; At the end of the rainfall, the amount of rainwater gradually decreases.

[0016] 2. The drain baffle can be adaptively adjusted according to different rainwater flows by optimizing the overflow adjustment device. When the rainwater volume is large, the drain baffle can open automatically to ensure that the rainwater is discharged quickly; when the rainwater volume is small, the drain baffle automatically rebounds to its initial position, restoring the facade to a beautiful and flat state.

The design of various overflow adjustment devices (such as the first limit baffle and the first automatic rebound hinge, the second limit baffle, the second automatic rebound hinge and the fixed shaft, the third limit baffle, the third automatic rebound hinge and the fixed plate, etc.) enables the drain baffle to be flexibly adjusted according to actual needs, ensuring the stability and efficiency of the device under different working conditions (vertical facade, upper curved facade).

[0018] 4. By using square and round reducers, square tube combinations or concentric reducers and second support tube combinations as transition fittings, the system can adapt to different pipe size and shape requirements and different working conditions (vertical facades, upper curved facades), increasing the flexibility and applicability of the design, ensuring the stability of rainwater in the pipe, avoiding fluid disturbances or eddies caused by sudden changes in pipe diameter, and improving the stability of the entire system.

[0029] The second limit baffle 32, the second automatic rebound hinge 35, the second water discharge baffle 42, the fixed shaft 37, the concentric reducer 23 and the second support pipe 24 are assembled to form a second rainwater overflow outlet device, which can effectively adapt to vertical facades and upper curved facades.

[0030] Embodiment 3: A rainwater overflow device for a building facade, such as Figure 5 , Figure 6 and Fig.10 As shown, the overflow adjustment device 3 includes a third limit baffle 33, a third automatic rebound hinge 36 and a fixed plate 38. The other end of the second support tube 24 is fixedly installed with a fixed plate 38.

[0032] Embodiment 4: A method for overflowing a rainwater overflow outlet device on a building facade, such as Figure 1-Figure 11 As shown, the following steps are included: Step A: Conduct on-site survey and make appropriate overflow devices according to the building facade curtain wall design; Ensure that the overflow device is matched with the building facade and rainwater discharge requirements, and make an appropriate selection based on whether the building facade is a vertical surface or an upper curved surface. The three automatic rebound hinges need to determine their rebound force according to the drainage baffle 4 respectively, so that the drainage baffle 4 pushed open by the impact of rainwater can be easily pulled.

[0033] Step B: Connect the rainwater pipe to the groove interface 5, and connect the rainwater pipe to the overflow device; The size of the groove interface 5 is determined according to the survey of the building rainwater pipe.

[0034] The water discharge baffle 4 can maintain the consistency of the building facade by painting the external color or sticking curtain wall glass of corresponding shape, and will not protrude from the building facade, thereby ensuring the concealment and aesthetics of the overflow outlet device.

[0035] Step C: When it rains, adaptive discharge is performed according to the amount of rainwater on the roof; In step C, when the amount of rainwater on the roof is small, the impact force of the rainwater is small, and the rainwater is discharged directly from the reserved gap between the water discharge baffle 4 and the transition receiving member 2 through the overflow device. At this time, the rainwater is on the same horizontal line as the transition receiving member 2, which will not affect the aesthetics; When the amount of rainwater increases, the drainage capacity of the reserved gap is insufficient, and the rainwater impacts the water discharge baffle 4 under the action of gravity, pushing the water discharge baffle 4 open, and the rainwater is discharged quickly at this time. The precipitation becomes larger, and after the overflow port is fully opened, a large amount of water is discharged; At the end of the rainfall, the amount of rainwater gradually decreases. At this time, the water discharge baffle 4 rebounds to the limit baffle through the automatic rebound folding, completing the entire overflow drainage process, and recovering and covering the overflow port.

[0036] Through the adaptive discharge mechanism, it is ensured that the system can effectively discharge rainwater under different rainfall conditions to avoid damage caused by water accumulation.
