Description

Technical Field

[0001] This utility model relates to the field of construction drainage technology, and more specifically, to a drain outlet structure with overflow function. Background Technology

[0002] Currently, the structural layers of roofs, slabs, or terraces, whether conventional or inverted, all contain leveling, slope-forming, waterproofing, and insulation layers between the structural layer and the rigid surface layer. As the rigid surface layer ages and fails, rainwater gradually seeps into the structural layers between them, causing water accumulation. If this water cannot be effectively drained, the rigid surface layer may arch, deform, or even crack due to thermal expansion caused by rising external temperatures, or it may freeze and thaw due to water freezing below freezing. Furthermore, as the water accumulates, the increased internal water pressure can lead to severe leakage in the interior space. Most existing drainage systems are designed to drain water from the rigid surface layer but cannot drain water between the rigid surface layer and the structural layer.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing drainage systems cannot drain water accumulated between the rigid surface layer and the structural layer.

[0005] This utility model is achieved through the following technical solution:

[0006] A drain outlet structure with overflow function is provided, comprising: an overflow pipe and a guide pipe, wherein one end of the overflow pipe is connected to one end of the guide pipe via an elbow; the overflow pipe is arranged horizontally and is located between the rigid surface layer and the structural layer, and is close to the structural layer; the guide pipe is arranged vertically and is located inside the drain pipe, and is in close contact with the inner wall of the drain pipe.

[0007] Furthermore, the bending angle of the elbow is ≥90°.

[0008] Furthermore, rubber sealing rings are provided at the connection points between the elbow and the overflow pipe, as well as at the connection points between the elbow and the guide pipe.

[0009] Furthermore, a rubber sealing ring is provided at the connection between the overflow pipe and the drain pipe.

[0010] Furthermore, a filter screen is provided at the end of the overflow pipe away from the elbow.

[0011] Furthermore, the end of the overflow pipe furthest from the elbow is an upward-facing oblique opening.

[0012] Furthermore, the length of the guide pipe is >20cm, the length of the overflow pipe is >20cm, and the diameter of the guide pipe and the overflow pipe is 16cm~25cm.

[0013] Furthermore, the overflow pipe, the guide pipe, and the elbow can all be made of metal or non-metal materials.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. The system employs a two-section structure consisting of an overflow pipe and a guide pipe, with the overflow pipe and guide pipe connected to form a bent structure. The overflow pipe is located between the rigid surface layer and the structural layer, allowing water to be drained away; the guide pipe is located inside the downpipe, allowing water to be discharged into the downpipe, thus solving the problem of existing drainage systems being unable to drain water between the rigid surface layer and the structural layer.

[0016] 2. Select elbows with a bending angle of 90° or greater, and ensure that the guide pipe is close to the wall of the drain pipe, so that the end of the overflow pipe is tilted upward, which is conducive to draining accumulated water.

[0017] 3. Rubber sealing rings are installed at the connection between the elbow and the overflow pipe, the connection between the elbow and the guide pipe, and the connection between the overflow pipe and the downpipe to prevent water leakage.

[0018] 4. A filter screen is installed at the port of the overflow pipe to prevent debris from entering the pipe and causing blockage.

[0019] 5. The overflow pipe has an upward-facing angled opening at the end, which facilitates the flow of accumulated water into the overflow pipe. Attached Figure Description

[0028] like Figure 1As shown, this utility model embodiment provides a drain outlet structure with overflow function, consisting of an overflow pipe, a guide pipe, and an elbow. One end of the overflow pipe 1 is connected to one end of the guide pipe 2 via an elbow 3. During installation, using the structural floor slab as the reference elevation, holes are drilled in the pipe wall of the drain pipe 4 in a direction perpendicular to the length of the drain pipe 4. Multiple holes can be drilled, evenly distributed in a plane. The overflow pipe 1 is horizontally positioned between the rigid surface layer and the structural layer, close to the structural layer, passing through the holes. The guide pipe 2 is vertically positioned inside the drain pipe 4, close to the inner wall of the drain pipe 4. When water accumulates between the rigid surface layer and the structural layer, under the action of pressure and gravity, the water is guided through the overflow pipe 1 into the guide pipe, then through the guide pipe 2 into the drain pipe 4, and finally drained away. When the drain pipe 4 is in drainage mode, the guide pipe 2 generates negative pressure due to siphon effect. At this time, the overflow pipe 1 accelerates drainage. This method minimizes water accumulation, ensures timely and effective drainage, and extends the building's lifespan.

[0029] It should be further noted that in this embodiment, the bending angle of the elbow 3 is ≥90°, and the guide pipe 2 is tightly attached to the wall of the downpipe 4. Therefore, the overflow pipe 1 is at a horizontal or upward angle near the structural layer, and the port of the overflow pipe 1 is an upward-opening angled opening, which facilitates the flow of accumulated water into the overflow pipe 1 and its discharge. Furthermore, rubber sealing rings are provided at the connection points of the elbow 3 and the overflow pipe 1, the elbow 3 and the guide pipe 2, and the overflow pipe 1 and the downpipe 4 to prevent water leakage. In addition, a filter screen 5 is provided at the port of the overflow pipe 1 to prevent debris from entering the pipe and causing blockage.

[0030] In terms of dimensions, the length of the guide tube 2 is >20cm, the length of the overflow tube 1 is >20cm, and the diameter of the guide tube 2 and the overflow tube 1 is 16cm~25cm.

[0031] In terms of material selection, overflow pipe 1, guide pipe 2 and elbow 3 can all be made of metal or non-metal materials.

[0032] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
