Abstract
Description
Technical Field
[0001] This application relates to the field of downpipe technology, and more particularly to roof downpipe structures. Background Technology
[0002] A downpipe roof is an organized drainage roof, meaning that roof water is first collected in the eaves gutters and then discharged to the ground through downpipes. Downpipes are a common method for draining rainwater and snowmelt from roofs in general residential buildings. It consists of grate drain outlets, rainwater hoppers, and downpipes, leading the drainage to the ground or connecting to rainwater pipes.
[0003] During long-term use, the roofing material may deform due to thermal expansion and contraction, or the downpipe may vibrate due to external forces, causing gaps to form at the connection between the downpipe and the roofing material. During rainy weather, rainwater can seep into the interior of the roof structure through these gaps, affecting the building's thermal insulation performance and service life.
[0004] Therefore, this application provides a roof downpipe structure. Utility Model Content
[0005] In view of the shortcomings of the prior art, this application provides a roof downpipe structure, which overcomes the shortcomings of the prior art and aims to solve the problem that during long-term use, the roof material may deform due to thermal expansion and contraction, or the downpipe may vibrate due to external forces, resulting in gaps at the connection between the downpipe and the roof material. During rainy weather, rainwater will seep into the interior of the roof structure through these gaps, which will affect the thermal insulation performance and service life of the building.
[0006] To achieve the above objectives, this application provides the following technical solution: a roof downpipe structure, including a roof base layer, a mounting hole provided at the top of the roof base layer, a reinforcing mechanism provided at the bottom of the roof base layer, the reinforcing mechanism including a mounting plate, the mounting plate being installed at the bottom end of the roof base layer, and screws being installed at the connection between the mounting plate and the roof base layer, a sleeve being fixedly installed at the bottom end of the mounting plate, two sets of stabilizing rings being installed inside the sleeve, a pipe body being installed at the mounting hole, two sets of stabilizing rings passing through the bottom of the pipe body, a sealing sleeve being installed at the connection between the pipe body and the roof base layer, the sealing sleeve being interference-fitted with the outer wall of the pipe body and the inner wall of the roof base layer, and a waterproof membrane being heat-fused to the top of the roof base layer.
[0007] By adopting the above technical solution, the pipe body is stably supported by a sealing sleeve, a reinforcement mechanism, and a waterproof membrane, using two sets of stabilizing rings connected to the sleeve, which improves the seismic resistance of the pipe body. When the roof base deforms due to thermal expansion and contraction, the sealing sleeve, due to its elasticity, can adaptively maintain a tight fit with the outer wall of the pipe body and the inner wall of the roof base, reducing the generation of gaps. The waterproof membrane forms a waterproof barrier on the top surface of the roof base, greatly improving the leak-proof performance of the roof base.

[0010] As a preferred technical solution of this application, a thermal insulation layer is fixedly installed between the waterproof membrane and the roof base layer.
[0011] By adopting the above technical solution, the thermal insulation performance of the roof base layer is improved through the thermal insulation layer. At the same time, in combination with the waterproof membrane, a double protection is formed, further enhancing the waterproof and thermal insulation effect of the roof base layer.
[0012] As a preferred technical solution of this application, a bracket is fixedly connected to the outer periphery of the expansion pipe, an insert plate is provided at the bottom of the bracket, a bolt is installed at the connection between the insert plate and the roof base layer, a waterproof coating is applied between the slope layer and the waterproof membrane, and the bolt extends between the waterproof coating and the waterproof membrane.
[0013] By adopting the above technical solution, the expansion pipe is further fixed to the roof base layer with bolts, which enhances the stability of the pipe after installation. The waterproof coating further improves the waterproof performance of the roof base layer. The waterproof coating and the waterproof membrane form a double waterproof defense line, which effectively prevents rainwater leakage. At the same time, the bolts extend between the waterproof coating and the waterproof membrane, reducing leakage from gaps and improving the waterproof effect.
[0014] As a preferred technical solution of this application, the inner wall of the expansion pipe is provided with a number of sets of guide grooves, and the number of sets of guide grooves are evenly arranged along the inner wall of the expansion pipe.
[0015] By adopting the above technical solution, rainwater is guided to flow quickly into the pipe body through the diversion channel, reducing the accumulation of rainwater in the expanded pipe and further improving drainage efficiency.
[0016] As a preferred technical solution of this application, a guide vane is fixedly installed inside the tube body, and the guide vane is arranged in a spiral shape.
[0017] By adopting the above technical solution, the spiral arrangement of the guide vanes can guide rainwater to form a spiral flow inside the pipe, increasing the flow rate of rainwater, improving drainage efficiency, while reducing the impact of rainwater on the inner wall of the pipe, reducing pipe wear, and extending the service life of the downpipe.
[0018] As a preferred technical solution of this application, a limiting ring is fixedly installed on the top of the tube body, a filter plate is snapped onto the top of the limiting ring, and a lifting rod is fixedly installed on the top of the filter plate.
[0019] By adopting the above technical solution, the filter plate can block debris such as leaves, branches, and dust from entering the pipe body, preventing blockage. The filter plate can be removed by lifting the rod, making it easy to clean and maintain.
[0020] As a preferred technical solution of this application, an anti-slip layer is fixedly installed on the outer surface of the expansion tube.
[0021] By adopting the above technical solution, the anti-slip layer can increase the friction between the expansion pipe and the roof base layer, further improving the stability after installation.
[0022] The beneficial effects of this application are:
[0023] 1. By using a sealing sleeve, reinforcement mechanism, and waterproof membrane, two sets of stabilizing rings are connected to the sleeve to provide stable support for the pipe body, which improves the seismic resistance of the pipe body. When the roof base deforms due to thermal expansion and contraction, the sealing sleeve, due to its own elasticity, can adaptively maintain a tight fit with the outer wall of the pipe body and the inner wall of the roof base, reducing the generation of gaps. The waterproof membrane forms a waterproof barrier on the top surface of the roof base, which greatly improves the leak-proof performance of the roof base.

[0031] Reference Figure 1-4 The roof drain pipe structure includes a roof base layer 1, with an installation hole 101 at the top and a reinforcement mechanism 2 at the bottom. The reinforcement mechanism 2 includes an installation plate 201, which is installed at the bottom of the roof base layer 1. Screws 202 are installed at the connection between the installation plate 201 and the roof base layer 1. A sleeve 203 is fixedly installed at the bottom of the installation plate 201. Two sets of retaining rings 204 are installed inside the sleeve 203. A pipe body 3 is installed at the installation hole 101. Two sets of retaining rings 204 pass through the bottom of the pipe body 3. A sealing sleeve 10 is installed at the connection between the pipe body 3 and the roof base layer 1. The sealing sleeve 10 is interference-fitted with the outer wall of the pipe body 3 and the inner wall of the roof base layer 1. A waterproof membrane 6 is heat-fused to the top of the roof base layer 1. An insulation layer 5 is fixedly installed between the waterproof membrane 6 and the roof base layer 1.
[0032] The pipe body 3 is stably supported by the sealing sleeve 10, the reinforcement mechanism 2, and the waterproof membrane 6, which are connected to the sleeve 203 by two sets of stabilizing rings 204, thus improving the seismic resistance of the pipe body 3. When the roof base layer 1 deforms due to thermal expansion and contraction, the sealing sleeve 10, due to its elasticity, can adaptively maintain a tight fit with the outer wall of the pipe body 3 and the inner wall of the roof base layer 1, reducing the generation of gaps. The waterproof membrane 6 forms a waterproof barrier on the top surface of the roof base layer 1, greatly improving the leak-proof performance of the roof base layer 1. The insulation layer 5 improves the insulation performance of the roof base layer 1, and together with the waterproof membrane 6, forms double protection, further enhancing the waterproof and insulation effects of the roof base layer 1.
[0033] Reference Figure 1-3An expansion pipe 4 is fixedly installed at the top of the pipe body 3, and a slope-finding layer 9 is provided at the top of the roof base layer 1; a bracket 7 is fixedly connected to the outer periphery of the expansion pipe 4, and an insert plate 701 is provided at the bottom of the bracket 7. A bolt 702 is installed at the connection between the insert plate 701 and the roof base layer 1. A waterproof coating 8 is applied between the slope-finding layer 9 and the waterproof membrane 6, and the bolt 702 extends to the space between the waterproof coating 8 and the waterproof membrane 6.
[0034] The slope layer 9 guides rainwater to the expansion pipe 4, allowing rainwater to flow quickly and smoothly into the pipe body 3, reducing the time rainwater stays on the roof and further reducing the risk of leakage. The expansion pipe 4 is further fixed to the roof base layer 1 by bolts 702, enhancing the stability of the pipe body 3 after installation. The waterproof coating 8 further improves the waterproof performance of the roof base layer 1. The waterproof coating 8 and the waterproof membrane 6 form a double waterproof defense line, effectively preventing rainwater leakage. At the same time, the bolts 702 extend between the waterproof coating 8 and the waterproof membrane 6, reducing leakage from gaps and improving the waterproof effect.
[0035] Reference Figure 1-3 The inner wall of the expansion pipe 4 is provided with several sets of guide channels 11, which are evenly arranged along the inner wall of the expansion pipe 4. A limit ring 13 is fixedly installed on the top of the pipe body 3, and a filter plate 14 is snapped onto the top of the limit ring 13. A lifting rod 15 is fixedly installed on the top of the filter plate 14. The guide channels 11 guide rainwater to flow quickly into the pipe body 3, reducing the accumulation of rainwater in the expansion pipe 4 and further improving drainage efficiency. The filter plate 14 can block leaves, branches, dust and other debris from entering the pipe body 3, preventing the pipe body 3 from becoming blocked. The filter plate 14 can be removed by the lifting rod 15 for easy cleaning and maintenance.
[0036] Reference Figure 2-4 Inside the pipe body 3, a guide vane 12 is fixedly installed, and the guide vane 12 is arranged in a spiral shape. An anti-slip layer 16 is fixedly installed on the outer surface of the expansion pipe 4. The spiral arrangement of the guide vane 12 can guide rainwater to form a spiral water flow inside the pipe body 3, increase the flow rate of rainwater, improve drainage efficiency, reduce the impact of rainwater on the inner wall of the pipe body 3, reduce the wear of the pipe body 3, and extend the service life of the downpipe. The anti-slip layer 16 can increase the friction between the expansion pipe 4 and the roof base layer 1, further improving the stability after installation.
[0037] Working principle: Through the sealing sleeve 10, the reinforcement mechanism 2, and the waterproof membrane 6, the pipe body 3 is stably supported by two sets of stabilizing rings 204 connected to the sleeve 203, which improves the seismic resistance of the pipe body 3. When the roof base layer 1 deforms due to thermal expansion and contraction, the sealing sleeve 10, due to its elasticity, can adaptively maintain a tight fit with the outer wall of the pipe body 3 and the inner wall of the roof base layer 1, reducing the generation of gaps. The waterproof membrane 6 forms a waterproof barrier on the top surface of the roof base layer 1, which greatly improves the leak-proof performance of the roof base layer 1. The slope layer 9 guides rainwater to the expansion pipe 4, and the expansion pipe 4 allows rainwater to flow into the pipe body 3 quickly and smoothly, reducing the time that rainwater stays on the roof and further reducing the risk of leakage.
[0038] Among them, the thermal insulation layer 5 improves the thermal insulation performance of the roof base layer 1, and together with the waterproof membrane 6, it forms a double protection, further enhancing the waterproof and thermal insulation effect of the roof base layer 1. The expansion pipe 4 is further fixed to the roof base layer 1 by the bolt 702, which enhances the stability of the pipe body 3 after installation. The waterproof coating 8 further improves the waterproof performance of the roof base layer 1. The waterproof coating 8 and the waterproof membrane 6 form a double waterproof defense line, effectively preventing rainwater leakage. At the same time, the bolt 702 extends between the waterproof coating 8 and the waterproof membrane 6, reducing the leakage of gaps and improving the waterproof effect.
[0039] Meanwhile, the guide channel 11 guides rainwater to flow quickly into the pipe body 3, reducing the accumulation of rainwater in the expansion pipe 4 and further improving drainage efficiency; the spiral arrangement of the guide plate 12 can guide rainwater to form a spiral water flow in the pipe body 3, increasing the flow rate of rainwater and improving drainage efficiency, while reducing the impact of rainwater on the inner wall of the pipe body 3, reducing the wear of the pipe body 3, and extending the service life of the downpipe.
[0040] In addition, the filter plate 14 can block debris such as leaves, branches, and dust from entering the pipe body 3, preventing blockage. The filter plate 14 can be removed by the lifting rod 15 for easy cleaning and maintenance. The anti-slip layer 16 can increase the friction between the expansion pipe 4 and the roof base layer 1, further improving the stability after installation.
