Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a lightning protection structure for an exhaust vent. Background Technology

[0002] In building roofing projects, vents are key structures for removing moisture from the insulation layer, but their metal pipes usually protrude from the roof surface, making them easy targets for lightning strikes.

[0003] Traditional lightning protection measures often involve directly welding or binding the down conductor to the exhaust pipe. This prolonged contact between the down conductor and the exhaust pipe in a humid environment accelerates metal corrosion, leading to system failure. Replacing or dismantling exposed lightning conductors requires damaging the roof structure, resulting in high maintenance costs and affecting waterproofing integrity. Furthermore, existing lightning conductor fixing structures are ill-suited to the installation requirements of exhaust pipes of different sizes. Therefore, while existing technologies may already offer solutions to these problems, this invention aims to provide an alternative or replacement solution. Utility Model Content

[0012] Beneficial effects

[0013] This utility model provides a lightning protection structure for an exhaust vent, which has the following advantages: the pre-embedded lightning protection lead is deeply buried in the slope-finding layer to avoid exposure and corrosion, and the bottom end of the exposed lightning protection lead is connected to the pre-embedded lightning protection lead through a connector, which facilitates the subsequent replacement of the exposed lightning protection lead.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figure 1-3 A lightning protection structure for an exhaust vent includes a structural base layer 1, a vapor barrier layer 2 above the structural base layer 1, a thermal insulation layer 3 above the vapor barrier layer 2, an exhaust pipe assembly 4 above the thermal insulation layer 3, a slope-finding layer 5 above the exhaust pipe assembly 4, an exhaust pipe 6 connected above the exhaust pipe assembly 4, and a lightning protection guiding structure embedded in the slope-finding layer 5, with one side of the lightning protection guiding structure connected to the exhaust pipe 6.

[0020] The lightning protection guiding structure includes: a pre-embedded lightning protection lead wire 7, an exposed lightning protection lead wire 8, a fixing block 9, a flipping block 10, a connecting plate 11, a threaded sleeve 12, a closing plate 13, a connecting screw 14, and an extension fixing assembly.

[0021] The pre-embedded lightning protection lead 7 is laid inside the slope-finding layer 5. The exposed lightning protection lead 8 passes through the slope-finding layer 5 and is connected to one end of the pre-embedded lightning protection lead 7. The fixing block 9 is located on one side of the exposed lightning protection lead 8. One end of the flipping block 10 is connected to one side of the fixing block 9 through a hinge. The connecting plate 11 is fixedly installed on the other side wall of the fixing block 9. The threaded sleeve 12 is fixedly installed on one side of the connecting plate 11. The closing plate 13 is fixedly installed on the other side of the flipping block 10. The connecting screw 14 is movably passed through the closing plate 13 and movably embedded in the threaded sleeve 12. One end of the extension fixing component is movably connected to the connecting plate 11.

[0022] During construction, the vapor barrier 2, insulation layer 3, exhaust pipe assembly 4, and slope-forming layer 5 are first laid sequentially on top of the structural base layer 1. The pre-embedded lightning protection conductor 7 is then laid within the slope-forming layer 5. Finally, the sealing coating 20 is laid on top of the slope-forming layer 5. Following this, according to the specifications of the exhaust pipe 6 above the exhaust pipe assembly 4, the extension fixing component is operated and connected to the exhaust pipe 6. Then, the exposed lightning protection conductor 8 is connected to the pre-embedded lightning protection conductor 7 via a double-threaded connector. The fixing block 9 is placed on one side of the exposed lightning protection conductor 8. Finally, under the connection of the hinge, the flipping block 10 is fastened. On the other side of the exposed lightning protection lead 8, it cooperates with the fixing block 9 to wrap the exposed lightning protection lead 8. Then, one end of the connecting screw 14 passes through the closing plate 13 and is embedded in the threaded sleeve 12 on one side of the connecting plate 11 to flip and limit the flipping block 10, ensuring the fixing effect of the exposed lightning protection lead 8. When the exposed lightning protection lead 8 is disassembled later, it is only necessary to take out the connecting screw 14 and twist the top of the exposed lightning protection lead 8 to separate the exposed lightning protection lead 8 from the double threaded connector, so as to realize the disassembly operation of the exposed lightning protection lead 8 without damaging the slope layer 5 and the sealing coating 20.

[0023] In the specific implementation process, the extension fixing component includes: mounting sleeve 15, extension rod 16, binding plate 17 and two binding frames 18;

[0024] The mounting sleeve 15 is fixedly installed on the side wall of the connecting plate 11. One end of the extension rod 16 is movably inserted through the mounting sleeve 15. The binding plate 17 is fixedly installed on the other end of the extension rod 16. Two binding frames 18 are respectively installed on both sides of the binding plate 17.

[0025] When connecting the exposed lightning protection lead 8 to the exhaust pipe 6, the staff adjusts the position of the extension rod 16 inside the mounting sleeve 15 according to the distance between the exposed lightning protection lead 8 and the exhaust pipe 6, so that the binding plate 17 fits against the side wall of the exhaust pipe 6. Then, the extension rod 16 is fixed in the position inside the mounting sleeve 15 by the mounting bolts 19. Then, the two ends of the metal strap are connected to the two binding frames 18 and put on the outside of the exhaust pipe 6, thus achieving the connection of the binding plate 17 and the purpose of fixing the exposed lightning protection lead 8 to the exhaust pipe 6.

[0026] In the specific implementation process, the mounting bolt 19 is movably embedded in the side wall of the mounting sleeve 15 to lock the position of the extension rod 16.

[0027] In the specific implementation process, a sealing coating 20 is laid on top of the slope layer 5 to ensure the overall waterproofness of the roof.

[0028] In the specific implementation process, the two binding frames 18 are connected to the exhaust pipe 6 by metal straps to achieve non-welding fixation and avoid damage to the pipe.
