Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a roof ventilation system. Background Technology

[0002] To ensure the waterproof performance of the roof, a waterproof layer needs to be laid on the roof surface to isolate it from external rainwater. Because the substrate beneath the waterproof layer has a high moisture content, and the waterproof layer has good sealing properties, moisture inside the roof substrate cannot escape. This causes water vapor to form beneath the waterproof layer, ultimately leading to bulging or cracking of the waterproof layer, thus affecting the overall waterproof performance and structural strength of the roof.

[0003] Traditional roof venting systems typically involve leaving venting channels with a longitudinal and transverse spacing of no more than 6cm within the slope layer and insulation layer. These channels are interconnected, with vertical vent holes at their intersections. These vent holes are permanent. Because many venting pipes extend beyond the roof, the overall appearance of the roof is unsightly, and the venting pipes are easily damaged or aged over time, leading to roof leaks. If the waterproof membrane is not properly treated at the vent holes, it can easily increase the number of leak points on the roof, while also increasing the cost of removing the vent holes and repairing the roof waterproofing, and prolonging the construction period.

[0004] Based on the above problems, this invention proposes a roof ventilation system. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a roof ventilation system. This utility model hides the ventilation pipe in the flue, improves the overall aesthetics of the roof, and reduces the risk of roof leakage.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A roof venting system includes a steam collection network and a venting pipe. The steam collection network is located between the base layer and the waterproof layer of the roof. The venting pipe includes a vertical section and a horizontal section. The vertical section is located inside the flue of the roof. The horizontal section is embedded between the base layer and the waterproof layer. One end of the horizontal section is connected to the steam collection network, and the other end extends into the flue and is connected to the vertical section through an elbow connector.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] This invention embeds the steam collection network beneath the waterproof layer, avoiding exposed steam venting pipes on the roof surface and reducing roof leakage points. Furthermore, the steam venting pipes in this invention are concealed inside the flue, preventing them from being exposed on the outside of the roof and effectively preventing them from aging due to sun exposure or damage from impacts, thus improving the aesthetics and service life of the roof. The vertical and horizontal sections of the steam venting pipes are connected by elbow connectors, which can prevent water from the base layer from flowing into the flue when the roof waterproof layer leaks.

[0010] As a preferred embodiment, a further technical solution of this utility model is:

[0011] Preferably, a connecting plate is pre-embedded on the inner wall of the flue, and the connecting plate is connected to the vertical section of the exhaust pipe through a pipe clamp installed on it.

[0012] Preferably, a conical top cover is provided at the top of the vertical section of the exhaust pipe, and the outer diameter of the bottom edge of the conical top cover is larger than the pipe diameter of the vertical section of the exhaust pipe.

[0013] Preferably, a fixing ring is provided at the top of the vertical section of the exhaust pipe, and at least two support rods are provided circumferentially around the center of the fixing ring. The fixing ring is connected to the conical top cover through the support rods.

[0014] Preferably, a protective net is provided between the outer wall of the fixing ring and the conical top cover.

[0015] Preferably, the steam collection network includes a horizontal steam collection pipe and a vertical steam collection pipe, which are vertically connected to form a network structure. Several steam collection holes are opened on the pipe walls of the horizontal steam collection pipe and the vertical steam collection pipe, and a steam permeable barrier is provided for the corresponding steam collection holes.

[0021] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0022] like Figures 1 to 4 As shown, a roof venting system is provided. The venting system mainly consists of a venting network 1 and a venting pipe 2. The venting network 1 is placed between the base layer 3 and the waterproof layer 4 of the roof. The venting network 1 consists of a horizontal venting pipe 101 and a vertical venting pipe 102. The horizontal venting pipe 101 and the vertical venting pipe 102 are vertically connected by a cross connector 103 to form a mesh structure. Several venting holes 104 are opened on the pipe walls of the horizontal venting pipe 101 and the vertical venting pipe 102 respectively. In order to prevent the venting holes 104 from being blocked during subsequent construction, a permeable barrier layer 105 is provided for each venting hole 104.

[0023] In this embodiment, the steam permeable layer 105 can be a dense mesh fabric, specifically, the dense mesh fabric is wrapped around the outside of the steam collecting pipe at the positions of the steam collecting holes 104 on the transverse steam collecting pipe 101 and the longitudinal steam collecting pipe 102.

[0024] The steam collection network 1 is connected to the exhaust pipe at the connection node between the roof and the flue 5. The exhaust pipe 2 is mainly composed of a vertical section 201 and a horizontal section 202. The vertical section 201 is placed inside the flue 5, and the horizontal section 202 is embedded between the base layer 3 and the waterproof layer 4. One end of the horizontal section 202 is connected to the steam collection network 1, and the other end extends into the flue 5 and is connected to the vertical section 201 through the elbow connector 203.

[0025] In this embodiment, a connecting plate 6 is pre-embedded on the inner wall of the flue 5, and a pipe clamp 7 is fixedly connected to the connecting plate 6. The exhaust pipe 2 is fixed to the inner wall of the flue 5 through the pipe clamp 7.

[0026] A fixing ring 8 is installed at the top of the vertical section 201 of the exhaust pipe 2; several support rods 10 are fixedly connected to the outer side of the fixing ring 8 around its center, with at least two support rods 10. A conical top cover 9 is fixedly connected to the top of the support rods 10, and the diameter of the outer edge of the bottom of the conical top cover 9 is larger than the pipe diameter of the vertical section 201 of the exhaust pipe. The conical top cover 9 prevents rainwater from entering the exhaust pipe 2.

[0027] A metal protective net 11 is provided between the outer wall of the fixing ring 8 and the inner wall of the conical top cover 9. The support rod 10 is placed inside the protective net 11 and serves as the support skeleton of the protective net 11. The protective net 11 has a cylindrical structure and is used to prevent flying insects and other foreign objects from entering the interior of the exhaust pipe.

[0028] When this exhaust system is in use, the water vapor below the waterproof layer 4 enters the steam collection network 1 through the steam collection hole 104, and then enters the exhaust pipe from the steam collection network 1. The water vapor in the exhaust pipe is discharged upward through the flue, thereby realizing the discharge of water vapor inside the steam collection network 1.

[0029] This invention lays a steam collection network between the roof base layer and the waterproof layer, and conceals the exhaust pipe in the flue. It utilizes the chimney effect to discharge the water vapor between the roof base layer and the waterproof layer through the flue. This not only hides the exhaust pipe, but also utilizes the chimney effect to better exhaust the steam.

[0030] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
