Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building drainage design, in particular to a building drainage outlet pipe structure which can effectively offset the settlement of the building. Background Art
[0002] Building settlement is usually inevitable. Foundation settlement calculations should be carried out in accordance with the relevant provisions of the national standard "Code for Design of Building Foundations". Any building that meets the standard is a qualified building.
[0003] The indoor domestic drainage pipes of the building are firmly fixed on the main structure. After passing through the wall of the building, the drainage pipes are buried and connected to the outdoor sewage well. If the main body of the building sinks, the indoor drainage pipes and the outdoor buried drainage pipes will inevitably sink unevenly with the wall as the boundary. In case of slight sinking, the drainage pipes can be adapted by passing through the gaps in the wall or slight deformation of the drainage pipes themselves, which will not affect the functional application of the drainage pipes. However, in case of large sinking, the drainage pipes may be flattened or damaged, which will cause sewage to flow out, or poor drainage for low-rise residents or even indoor water backflow. Summary of the invention
[0004] The utility model aims to provide a building drainage pipe structure to solve the defects of the prior art.
[0005] In order to achieve the above purpose, the utility model can adopt the following technical solutions:
[0006] The utility model discloses a building drainage outlet pipe structure, comprising an outlet drainage pipe passing through a building wall to the outdoors, the outlet end of the outlet drainage pipe is connected to a vertical water outlet pipe through a 90° elbow, the lower end of the vertical water outlet pipe is connected to a buried pipe, the water inlet end of the buried pipe is provided with a vertical flared joint sleeved with the gap of the vertical water outlet pipe, an elastic sealing ring of an annular structure is provided in the gap between the vertical flared joint and the vertical water outlet pipe, a corrugated pipe is sleeved on the outer sides of the vertical flared joint and the vertical water outlet pipe, the upper end of the corrugated pipe is sleeved with an upper pipe clamp fixed on the outer wall of the vertical water outlet pipe, and the lower end of the corrugated pipe is sleeved with a lower pipe clamp fixed on the outer wall of the vertical flared joint.
[0007] Furthermore, a flexible waterproof sleeve is provided in the opening of the building wall and is sleeved on the outgoing drainage pipe.
[0008] The utility model has the advantages that the gap sleeve connection between the vertical water outlet pipe and the vertical flared joint is utilized to realize the vertical connection of the household drainage pipe and the buried pipe, and at the same time, the elastic sealing ring arranged between the vertical flared joint and the vertical water outlet pipe and the corrugated pipe sleeved on the vertical flared joint and the outer side of the vertical water outlet pipe are utilized to realize the flexible connection, so that when the household drainage pipe sinks downward together with the building, the vertical water outlet pipe can move downward in the vertical flared joint to ensure the sealing of the connection between the household drainage pipe and the buried pipe, effectively overcome the damage to the household drainage pipe caused by the settlement of the building, avoid the phenomenon of flattening or damage and rupture of the household drainage pipe, always keep the household drainage pipe and the buried pipe connected, and prevent the outflow of sewage or the backflow of water in the indoor room of the low-rise residents. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] Figure 2 yes Figure 1 Enlarged view of part A in the middle. DETAILED DESCRIPTION
[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0012] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0013] like Figure 1 , 2 As shown, the building drainage outlet pipe structure described in the utility model includes an outlet drainage pipe 2 that passes horizontally from the building wall 1 to the outdoors. The outlet drainage pipe 2 can be made of materials such as PVC-U, PP, PE or gray cast iron, and its outlet end is connected to a vertical outlet pipe 4 vertically downward through a 90° elbow 3.
[0014] The lower end of the vertical water outlet pipe 4 is connected to the buried pipe 5 located outside the building wall 1. Specifically, a vertical flared joint 6 is arranged at the water inlet end of the buried pipe 5. The inner diameter of the vertical flared joint 6 should be slightly larger than the outer diameter of the vertical water outlet pipe 4, so that the vertical flared joint 6 can be sleeved with the vertical water outlet pipe 4 in the gap, thereby realizing the vertical connection between the vertical flared joint 6 and the vertical water outlet pipe 4. At this time, an elastic sealing ring 7 of an annular structure is arranged in the gap between the vertical flared joint 6 and the vertical water outlet pipe 4, and a corrugated pipe 8 is sleeved on the outer side of the vertical flared joint 6 and the vertical water outlet pipe 4. The upper end of the corrugated pipe 8 is sleeved with an upper pipe clamp 9 fixed on the outer wall of the vertical water outlet pipe 4, and the lower end of the corrugated pipe 8 is sleeved with a lower pipe clamp 10 fixed on the outer wall of the vertical flared joint 6, thereby realizing a flexible connection between the vertical flared joint 6 and the vertical water outlet pipe 4 under the premise of ensuring the sealing of the vertical flared joint 6 and the vertical water outlet pipe 4.
[0015] In addition, in order to further improve the anti-subsidence performance of the household drainage pipe 2 where it passes horizontally through the building wall 1, a flexible waterproof casing 11 can be arranged in the hole of the building wall 1, so that the household drainage pipe 2 passes through the flexible waterproof casing 11, thereby utilizing the compressive deformation of the flexible waterproof casing 11 to offset the building settlement pressure on the household drainage pipe 2.
[0016] The entire building drainage outlet pipe structure utilizes the gap sleeve connection between the vertical water outlet pipe 4 and the vertical flared joint 6 to realize the vertical connection between the household drainage pipe 2 and the buried pipe 5. At the same time, the elastic sealing ring 7 arranged between the vertical flared joint 6 and the vertical water outlet pipe 4 and the corrugated pipe 8 sleeved on the vertical flared joint 6 and the outside of the vertical water outlet pipe 4 are utilized to realize flexible connection. Therefore, when the household drainage pipe 2 sinks downward with the building, the vertical water outlet pipe 4 can move downward in the vertical flared joint 6 to ensure the sealing of the connection between the household drainage pipe 2 and the buried pipe 5, effectively overcome the damage to the household drainage pipe 2 caused by the settlement of the building, avoid the phenomenon of flattening or damage and fracture of the household drainage pipe 2, always keep the household drainage pipe 2 connected with the buried pipe 5, and prevent sewage from flowing out or backflow in the indoor room of low-rise residents.
