Description

Technical Field

[0001] This utility model relates to the field of flue structure technology, and in particular to a multi-layer waterproof enclosure structure at the junction of flue and roof. Background Technology

[0002] In building construction, roof flues serve as crucial channels for exhausting fumes, and the junction between the roof and the flue is a critical point for waterproofing. Because this area is constantly exposed to the natural environment, it must withstand various external factors such as rainwater erosion, temperature changes, and wind loads. Inadequate waterproofing can easily lead to leaks, not only affecting the flue's normal operation but also potentially seeping into the roof structure, causing a series of safety hazards such as damp walls, steel corrosion, and reduced structural strength. In severe cases, it can even affect the building's lifespan.

[0003] The existing waterproofing structures at the junction of roof flues and roofs mostly use a single sealant or a simple water-blocking plate design. While the sealant sealing method is simple to apply, over time, the sealant gradually loses its elasticity due to aging, high temperatures, and other factors, leading to a decline in sealing performance and eventually water leakage. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a multi-layer waterproof enclosure structure at the junction of the flue and the roof.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] The multi-layer waterproof enclosure structure at the junction of the flue and the roof includes a mounting base, a mounting pipe vertically fixed to the mounting base, and a bend fixedly connected to the upper end of the mounting pipe; the air outlet direction of the bend is parallel to the roof.

[0007] Preferably, the mounting base has multiple mounting holes, and multiple mounting bolts pass through the mounting holes to fix the mounting base to the roof.

[0008] Preferably, the bottom of the mounting pipe is coaxially provided with a threaded pipe, which is spirally installed on the roof embedded parts or waterproof base.

[0009] Preferably, a fixed seat is fixedly provided on the outer wall of the bend, a clamping rod is rotatably installed on the fixed seat, and a rotating plate for sealing the air outlet of the bend is fixedly connected to the end of the clamping rod away from the fixed seat.

[0010] Preferably, a torsion spring is installed at the connection between the lever and the fixed base.

[0011] Preferably, a handle is fixedly installed on the outer surface of the rotating plate.

[0012] Preferably, the spring force of the torsion spring drives the rotating plate to maintain a closed state on the air outlet of the bend.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through multiple designs such as tight fixing of the mounting base to the roof and the setting of sealing gaskets, threaded connection of the mounting pipe and sealant assistance, and automatic sealing of the bend pipe air outlet turn plate, a comprehensive waterproof system is formed, which can effectively prevent rainwater from seeping into the junction of the flue and the roof.

[0015] 2. The multi-point fixing method ensures structural stability, the threaded connection facilitates installation and disassembly, the rotating plate handle is convenient for manual operation, and the torsion spring realizes the automatic reset of the rotating plate, which takes into account both the ease of installation and the convenience of later maintenance.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

[0023] Reference Figs. 1-3 The multi-layered waterproof enclosure structure at the junction of the flue and the roof includes a mounting base 1, a mounting pipe 3 vertically fixed to the mounting base 1, and a bend 4 fixedly connected to the upper end of the mounting pipe 3. The outlet direction of the bend 4 is parallel to the roof. This design can effectively prevent rainwater from directly entering the flue and form the first waterproof barrier from the outlet angle.

[0024] As the fundamental load-bearing component of the entire structure, the stability of the mounting base 1 directly affects the waterproofing effect. To ensure a secure installation, multiple mounting holes 2 are provided on the mounting base 1. During installation, multiple mounting bolts pass through the mounting holes 2 to firmly fix the mounting base 1 to the roof. This multi-point fixing method can distribute the structural weight and external loads (such as wind force and snow pressure), preventing the mounting base 1 from loosening or shifting due to uneven stress, thereby avoiding gaps at the joints that could lead to leakage. Simultaneously, a waterproof sealing gasket can be added to the contact area between the mounting base 1 and the roof to further enhance the waterproofing performance of the base layer.

[0025] As the intermediate structure connecting the mounting base 1 and the bend 4, the sealing performance of the mounting pipe 3 is crucial. A threaded pipe 9 is coaxially mounted at the bottom of the mounting pipe 3, and the threaded pipe 9 is spirally installed onto the roof embedded parts or waterproof base. The threaded connection not only facilitates installation and disassembly but also forms a waterproof barrier through the tight interlocking of the threads, effectively preventing rainwater from seeping in through the gap between the mounting pipe 3 and the base. Furthermore, waterproof sealant can be applied to the threaded joints to further enhance the waterproof rating.

[0026] As the terminal connecting the flue to the outside world, the protective design of the outlet of the elbow 4 is particularly crucial. A fixed base 5 is fixedly installed on the outer wall of the elbow 4, and a locking rod 6 is rotatably mounted on the fixed base 5. A rotating plate 7 for sealing the outlet of the elbow 4 is fixedly connected to the end of the locking rod 6 away from the fixed base 5. The rotating plate 7 can seal the outlet when the flue is not in operation, preventing rainwater, debris, etc., from entering the flue. A torsion spring is installed at the connection between the locking rod 6 and the fixed base 5. The spring force drives the rotating plate 7 to maintain the sealed state of the outlet of the elbow 4, ensuring effective protection in the non-operating state. When the flue is in operation, the internal air pressure will push the rotating plate 7 to overcome the spring force of the torsion spring and open, ensuring smooth exhaust of flue gas. After operation stops, the rotating plate 7 automatically resets under the action of the torsion spring, resealing the outlet, achieving intelligent protection.

[0027] To facilitate manual operation of the rotating plate 7, a handle 8 is fixedly installed on the outer surface of the rotating plate 7 when cleaning the flue or inspecting the air outlet. The handle 8 provides a convenient point of force for opening the rotating plate 7, making it easy for operators to control the state of the rotating plate 7 when working on the roof, thus improving the convenience of maintenance.

[0028] In summary, this multi-layered waterproof enclosure structure, through the secure fixing of the mounting base, the threaded sealing of the mounting pipe, the protective plate of the bend in the air outlet, and the automatic reset of the torsion spring, forms a multi-layered, all-round waterproof system. It can effectively deal with the leakage problem at the junction of the roof flue, while taking into account the convenience of installation and maintenance, and is suitable for waterproof protection scenarios of various roof flues.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
