Description

Technical Field

[0001] This application relates to the field of roof drainage technology, and in particular to a drainage system for curved roofs and its maintenance and construction method. Background Technology

[0002] With the upgrading of people's aesthetic standards, many large public buildings have adopted irregularly shaped curved roofs, which are rich in shape and highly aesthetically pleasing. However, they also present problems such as numerous water accumulation surfaces and multiple water flow directions. Due to the numerous overlapping points and complex junctions in the drainage structure of irregularly shaped curved roofs, the waterproof membrane needs to be cut extensively, resulting in poor drainage structure integrity and a tendency for water leakage. To improve roof leakage, various structures such as gutters, collection channels, rainwater hoppers, external decorative components, and irregularly shaped skylights are typically installed on irregularly shaped curved roofs. To protect the aesthetics of the curved roof, the collection channels are usually located at the bottom of the troughs of the curved roof, and their direction follows the extension of the troughs. Maintenance requires the disassembly of the top curved spliced ​​panels, and curved roofs generally have poor load-bearing capacity, making them prone to damage during maintenance. Furthermore, curved roofs are usually formed by splicing large areas of panels; if a panel is damaged, the entire structure needs to be remanufactured. Due to the curvature of the curved surface, the curvature of each spliced ​​panel is inconsistent, making production difficult and maintenance inconvenient. Summary of the Invention

[0003] To address the potential damage to the curved surface of a roof caused by subsequent maintenance, this application provides a drainage system for curved roofs and its construction method.

[0004] In a first aspect, this application provides a drainage system for curved roofs, employing the following technical solution:

[0005] A drainage system for curved roofs includes a main drainage frame, several permeable covers, and several drainage channels. The main drainage frame is provided with drainage channels, and the permeable covers are arranged in a row and cover the top of the drainage channels. The main drainage frame includes two main support bones and a connecting bone connecting the two main support bones. The drainage channels are located between the two main support bones.

[0006] The main support bones have connecting grooves through their opposing surfaces, and connecting blocks are inserted into the connecting grooves. The ends of the connecting blocks protrude from the inner walls of the two main support bones that are close to each other. Several drainage ditches are arranged in a row in the drainage channel, and the ends of adjacent drainage ditches are heat-welded and sealed. Each drainage ditch includes a main ditch and supporting protrusions on both sides of the top opening of the main ditch. Two supporting protrusions are mounted above the connecting blocks.

[0007] By adopting the above technical solution, water tends to collect in the troughs of the curved roof, which can easily lead to leakage. The drainage structure is located below the troughs of the curved roof, and the lowest point of the trough is located on the top of the permeable cover. If water seeps in at the trough, it tends to collect at the trough and then drip onto the permeable cover.

[0008] During maintenance, after removing the connecting block from the connecting groove, the limiting effect of the connecting block on the drainage ditch disappears, making it convenient to maintain or replace the drainage ditch, allowing maintenance to be performed from the bottom of the roof. Firstly, personnel do not need to go to the top of the roof for maintenance, ensuring high safety. Secondly, there is no need to disassemble the curved roof panels, eliminating the risk of damage during disassembly. Thirdly, the load-bearing capacity of roofs is typically lower than that of conventional roofs; maintenance at the top of the roof could lead to localized overload and damage, while maintenance at the bottom avoids this problem.

[0009] Optionally, the bottom of the permeable cover is provided with a guide plate, the top of the guide plate is integrally formed on both sides of the bottom of the permeable cover, the bottom of the guide plate extends towards the center of the bottom of the main channel in a mutually approaching direction, and a plurality of permeable grooves are opened in the middle of the permeable cover, the projection of the plurality of permeable grooves toward the bottom of the permeable cover is located between the connection between the two guide plates and the permeable cover.

[0010] By adopting the above technical solution, the tops of the two guide plates are integrally formed on both sides of the bottom of the permeable cover, allowing water to enter from the permeable channel and fall directly into the drainage ditch through the guide plates, and then be discharged from the eaves through the drainage ditch. The guide plates prevent water from easily reaching the drainage ditch, thereby reducing water seepage at the gap between the drainage ditch and the main support frame. At the same time, the guide plates also reduce noise when water falls into the drainage ditch.

[0011] Optionally, the top surfaces of the main support bones are provided with steps for placing the water-permeable cover at their close ends. The steps are provided with water-blocking protrusions, and the water-permeable cover is provided with a water-blocking groove for accommodating the water-blocking protrusions. The inner wall of the water-blocking groove is attached to the outer wall of the water-blocking protrusions.

[0012] By adopting the above technical solution, the water-blocking protrusions prevent water from easily seeping directly into the gap between the main support frame and the water-permeable cover.

[0013] Optionally, the connecting bone is located below the permeable cover and above the supporting protrusion, with the top surface of the supporting protrusion abutting against the bottom of the connecting bone.

[0014] By adopting the above technical solution, the supporting convex plate is pressed against the connecting bone by the connecting block, so that the installation is stable and it is not easy to vibrate and make noise when the wind blows.

[0015] Optionally, the connecting block end on different main support bones protrudes from the sidewalls of the two main support bones that are far apart from each other.

[0016] By adopting the above technical solution, the end of the connecting block protrudes from the sidewalls of the two main supporting bones that are far apart from each other, making the connecting block easy to disassemble.

[0017] Optionally, it also includes several anti-detachment covers, which are arranged in a row and spliced ​​below the main support frame. The ends of adjacent anti-detachment covers are heat-welded and sealed. Guide slopes are provided on the end faces of the connecting blocks on different main support frames that are far apart from each other. The guide slopes on the connecting blocks on different main support frames are inclined downwards and close to each other.

[0018] The anti-detachment cover includes a connecting plate and anti-detachment clamps disposed at both ends of the top surface of the connecting plate. Anti-detachment strips are fixed to the top of the anti-detachment clamps on one side close to each other. When the anti-detachment cover moves upward to cover the drainage channel, the anti-detachment clamps are located on both sides of the two main support bones, and the two anti-detachment strips slide down by abutting against the two guide slopes to separate their side walls. After the anti-detachment strips move to the top of the connecting block, the anti-detachment strips are close to each other and locked above the connecting block. The ends of the connecting blocks on different main support bones that are far apart from each other abut against the side walls of the connecting plate that are close to each other.

[0019] By adopting the above technical solution, the anti-detachment cover can divert leaking water, improving the roof's leak-proof performance, while also serving a decorative purpose to enhance the roof's interior appearance. Furthermore, it secures the connecting blocks on different main support frames together, preventing them from detaching and causing injury. The guide ramp facilitates the anti-detachment cover's snap-in installation.

[0020] Secondly, this application provides a maintenance and construction method for a drainage system for curved roofs, which adopts the following technical solution:

[0021] A maintenance and construction method for the above-mentioned drainage system for curved roofs includes the following steps:

[0022] S1, Locate the leak: Observe the situation at the leaking section to determine the location and cause of the leak;

[0023] S2, Construction based on the cause of the leak:

[0024] S21. If the leakage problem is caused by a large area of ​​cracked drainage ditch, the drainage ditch needs to be replaced. First, remove the connecting blocks on both sides of the cracked drainage ditch and take the connecting blocks out of the connecting groove. Cut off the leaking section of the drainage ditch and then cut a section of the same length from the intact drainage ditch in the repair building material according to the length of the cut drainage ditch. Then, put the repaired section of the drainage ditch into the empty space and install the connecting blocks back into the connecting groove to support the repaired section of the drainage ditch. Then, heat weld the two ends of the repaired section of the drainage ditch from the bottom of the drainage ditch to make the two ends sealed.

[0025] S22. If the leakage problem is due to incomplete welding at the weld between adjacent drainage ditches or small cracks in the drainage ditch, then the weld or small crack in the adjacent drainage ditch should be cleaned and repaired by welding.

[0026] By adopting the above technical solution, roof maintenance can be carried out at the bottom of the roof, making the operation convenient, the construction safety of workers is high, and the roof is not easily damaged, making maintenance convenient.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The proposed solution facilitates maintenance inside the roof, making the curved roof less susceptible to damage during maintenance, thus ensuring the integrity of the roof and making maintenance convenient.

[0029] 2. The deflector plate directs the water flow, improving the roof's waterproofing while reducing water flow noise;

[0030] 3. The anti-detachment cover further improves the roof's leak-proof performance and also makes the connecting blocks less likely to fall off. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a drainage system for curved roofs. (Refer to...) Figure 1 and Figure 2 The drainage system for curved roofs includes a main drainage frame 1, several permeable covers 2, and several drainage channels 3. The main drainage frame 1 is equipped with a drainage channel 4. The main drainage frame 1 includes two parallel main support bones 11 and a connecting bone 12 connecting the two main support bones 11. The drainage channel 4 is located between the two main support bones 11.

[0036] One main support bone 11 is fixed to each end of the connecting bone 12. Multiple connecting bones 12 are provided and arranged at intervals. A leveling plate 13 is welded to the top of each main support bone 11. The bottom of two leveling plates 13 on one side are sealed and welded to the top surface of the main support bone 11. The top of the leveling plate 13 is welded to the bottom of the curved sheet material, ensuring that the sidewalls of the two main support bones 11 are vertically aligned. A weight-reducing cavity is provided inside the main support bone 11 to reduce weight and lower the load-bearing burden on the curved roof.

[0037] Several permeable covers 2 are arranged in a row and cover the top of the drainage channel 4, with the connecting rib 12 located below the permeable covers 2. Steps 14 for placing the permeable covers 2 are provided at the ends of the main support ribs 11 that are close to each other. Water-blocking protrusions 15 are welded onto the steps 14. Water-blocking grooves 21 are provided on the permeable covers 2 to accommodate the water-blocking protrusions 15, with the inner wall of the groove 21 fitting against the outer wall of the water-blocking protrusions 15. The permeable covers 2 are 1-2m long and made of polypropylene. The ends of adjacent permeable covers 2 are heat-welded and sealed.

[0038] Several connecting grooves 5 are provided through the faces of the main support bones 11. The connecting grooves 5 are arranged at intervals along the length of the main support bones 11, and the gap between the connecting grooves 5 is 40-80cm. Connecting blocks 51 are inserted into the connecting grooves 5 one by one. The ends of the connecting blocks 51 protrude from the inner walls of the two main support bones 11 that are close to each other.

[0039] Drainage channels 3 are arranged in a row within the drainage channel 4. The drainage channels 3 are made of thermoplastic polypropylene, and the ends of adjacent drainage channels 3 are heat-welded and sealed. Each drainage channel 3 includes a main channel 31 and two integrally formed support protrusions 32 on both sides of the top opening of the main channel 31. The two support protrusions 32 extend in a direction away from each other and are mounted above the connecting block 51. The connecting rib 12 is located above the support protrusions 32, and the connecting block 51 presses the drainage channels 3 against the bottom surface of the connecting rib 12, ensuring stable installation of the drainage channels 3.

[0040] The top edges of the two rows of connecting blocks 51 that are close to each other are provided with a first chamfer, and the bottom edges of the two supporting protrusions 32 that are far from each other are provided with a second chamfer. The first chamfer facilitates the insertion of the connecting blocks 51 into the connecting groove 5. After the first and second chamfers are matched, it is convenient to press the supporting protrusions 32 upwards, thereby facilitating the pressing of the supporting protrusions 32 against the connecting bone 12. A guide plate 22 is provided at the bottom of the permeable cover 2. The top of the guide plate 22 is integrally formed on both sides of the bottom of the permeable cover 2, and the bottom of the guide plate 22 extends towards the center of the bottom of the main groove 31 in the direction of mutual approach. The distance between the bottom of the guide plate 22 and the main groove 31 plate is 1-2cm.

[0041] The permeable cover 2 has several permeable channels 23 in the middle. The projection of the permeable channels 23 toward the bottom of the permeable cover 2 is located between the connection between the two guide plates 22 and the permeable cover 2, so that water enters from the permeable channels 23 and is directly guided into the drainage ditch 3 through the guide plates 22. The width of the permeable channels 23 is 0.5-1cm, making it difficult for larger debris to enter.

[0042] The ends of the two rows of connecting blocks 51 on different main support bones 11 protrude from the sidewalls of the two main support bones 11 that are far apart from each other. Guide slopes 511 are provided on the end faces of the connecting blocks 51 on different main support bones 11 that are far apart from each other. The guide slopes 511 on the connecting blocks 51 on different main support bones 11 are inclined downwards and close to each other.

[0043] The drainage system for curved roofs also includes several anti-detachment covers 6, which are arranged in a row below the main support frame 11. The anti-detachment covers 6 are made of thermoplastic plastic, specifically polypropylene, and the ends of adjacent anti-detachment covers 6 are heat-welded to seal them. The length of each anti-detachment cover 6 is 1m.

[0044] The anti-detachment cover 6 includes a connecting plate 61 and anti-detachment clamps 62 integrally formed on both ends of the top surface of the connecting plate 61. The two anti-detachment clamps 62 are arranged in parallel. The top surface of the connecting plate 61 is a concave arc surface, which facilitates water collection and also serves as a device.

[0045] Anti-detachment strips 63 are integrally formed on the top sides of the anti-detachment clamps 62, close to each other. When the anti-detachment cover 6 moves upward to cover the drainage channel 4, the two anti-detachment clamps 62 are located on both sides of the two main support bones 11. When the two anti-detachment strips 63 slide upward against the two guide slopes 511, the two anti-detachment strips 63 move away from each other to separate. When the anti-detachment strips 63 move to the top of the connecting block 51, the anti-detachment strips 63 rebound and move closer to each other to lock onto the top of the connecting block 51. The ends of the connecting blocks 51 on different main support bones 11 that are far apart from each other abut against the sides of the connecting plates 61 that are close to each other.

[0046] The implementation principle of a drainage system for curved roofs according to an embodiment of this application is as follows: the trough of the curved roof gradually slopes downwards towards the eaves, the drainage structure is located below the trough, and the top of the permeable cover 2 in the trough of the curved roof is where rainwater collects and flows. If seepage occurs in the trough, water droplets fall onto the permeable cover 2. The length of the drainage structure extends along the direction of the trough of the curved roof and gradually slopes downwards towards the eaves. Water entering the drainage ditch 3 is guided through the drainage ditch 3 to the edge of the eaves for discharge.

[0047] This application also discloses a maintenance and construction method for a drainage system for curved roofs, including the following steps:

[0048] S1, Locate the leak: Observe the situation at the leaking section to determine the location and cause of the leak;

[0049] S2, Construction based on the cause of the leak:

[0050] S21. If the cause of the leak is a large-area crack or damage to the anti-detachment cover 6, the anti-detachment cover 6 needs to be replaced. After cutting the anti-detachment cover 6 of the leaking section, use a tool to pry up the anti-detachment strip 63 so that the anti-detachment strip 63 is released from the state of being stuck on the connecting block 51 and removed. Then, according to the length of the cut-off anti-detachment cover 6, cut a section of the same length from the intact anti-detachment cover 6 in the repair building material. Re-clamp the anti-detachment cover 6 of the repair section onto the connecting block 51. Then, heat-weld the two ends of the anti-detachment cover 6 of the repair section to the ends of the adjacent anti-detachment cover 6 to seal them.

[0051] If the anti-detachment cover 6 is intact, cut the anti-detachment cover 6 as long as possible, making sure the cut position does not coincide with the original hot weld. Then, use a tool to pry up the anti-detachment strip 63, so that the anti-detachment strip 63 is released from the state of being stuck on the connecting block 51 and remove it. Inspect the remaining positions. After the inspection is completed, re-clamp the cut-off anti-detachment cover 6 onto the connecting block 51, and then heat-weld the two ends of the cut-off anti-detachment cover 6 to the ends of the adjacent anti-detachment cover 6 to seal them.

[0052] S22. If the leakage problem is caused by a large area of ​​cracking or damage to the drainage ditch 3, the drainage ditch 3 needs to be replaced. First, remove the connecting blocks 51 on both sides of the cracked drainage ditch 3, take the connecting blocks 51 out of the connecting groove 5, cut off the leaking section of the drainage ditch 3, and then cut a section of the same length from the intact drainage ditch 3 in the repair building material according to the length of the cut drainage ditch 3. Then, put the repaired section of the drainage ditch 3 into the empty space, and then install the connecting blocks 51 back into the connecting groove 5 to support the repaired section of the drainage ditch 3. Then, heat weld the two ends of the repaired section of the drainage ditch 3 from the bottom of the drainage ditch 3 to make the two ends sealed.

[0053] S23, if the leakage problem is due to incomplete welding at the weld between adjacent drainage ditch 3 or adjacent anti-detachment cover 6, then clean the weld of the adjacent drainage ditch 3 or the weld between adjacent anti-detachment cover 6 and repair the welding.

[0054] S24. If the water leakage problem is caused by small cracks in the drainage ditch 3 or the anti-detachment cover 6, then the small cracks should be repaired by welding.

[0055] The implementation principle of the maintenance and construction method of the drainage system for curved roof in this application embodiment is as follows: by performing maintenance and other operations on the curved roof at the bottom of the roof, personnel do not need to go to the top of the roof for maintenance, which is highly safe; during maintenance, it is usually not necessary to disassemble the curved roof sheet, so there is no problem of damage to the curved sheet during disassembly; at the same time, it is not easy to damage the roof, reducing roof damage.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
