Description

Technical Field

[0001] The present application relates to the technical field of metal roof enclosure systems, and in particular to a metal roof ridge node waterproofing structure and method. Background Art

[0002] In the metal roof enclosure system, the waterproof performance of the ridge node is one of the key factors to ensure the safety and durability of the entire roof structure. Traditional metal roofs often have many deficiencies in the design of the ridge node, resulting in frequent water leakage problems, which seriously affects the use function and life of the building.

[0003] In the traditional ridge node design, the overlap between the ridge cover plates is usually connected only by nails. The spacing between the connection nails is too large, and the nail hole design is unreasonable, which causes the connection nails to fall off due to temperature shrinkage, causing water leakage at the nail holes. The overlap is only sealed with sealant without butyl tape, which directly leads to flash leakage at the overlap between the ridge cover plates. At the same time, effective waterproofing measures such as butyl tape are often not set at the overlap of the ridge cover plates and the metal roof panel plugs (ridge water retaining plates) on both sides of the ridge, so that there are gaps between the overlap and the plugs and the metal roof panels, which become potential risk points for water leakage. In addition, the direct nailing connection between the ridge cover plate and the metal roof panel also exacerbates the problem of nail hole leakage. In addition, the size design of the triangular ridge in the middle of the ridge cover plate is unreasonable, which cannot effectively cope with the deformation of the metal roof panel due to thermal expansion and contraction, causing the connection nails to fall off, further exacerbating the water leakage phenomenon.

[0004] Therefore, a new and efficient metal roof ridge node waterproofing solution is urgently needed to meet the increasingly high requirements for metal roof ridge node waterproofing performance and durability. Summary of the invention

[0036] Figure 1 A structural schematic diagram of a metal roof ridge node waterproof structure of the present application is shown. Figure 4 A schematic diagram of the installation structure of a ridge water retaining plate near the ridge of a metal roof ridge node waterproof structure of the present application is shown. Figure 5 A schematic diagram of the installation structure of a ridge water retaining plate at a far ridge of a metal roof ridge node waterproof structure of the present application is shown. Figure 6 The schematic diagram of the ridge flashing installation structure of a metal roof ridge node waterproof structure of the present application is shown. Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the present application provides a metal roof ridge node waterproof structure, comprising:

[0037] The metal roof panel 1 is provided with a near-ridge water retaining plate 3 and a far-ridge water retaining plate 4; a ridge flashing plate 8 is provided above the near-ridge water retaining plate 3 and the far-ridge water retaining plate 4. Fig.10 The schematic diagram of the far ridge water retaining plate structure of a metal roof ridge node waterproof structure of the present application is shown. Fig.10The top surface 43 of the far ridge water retaining plate 4 is turned outward and fixedly connected to the two side edges of the ridge flashing plate 8; the far ridge water retaining plate 4 is fixedly connected to the metal roof panel 1 through a U-shaped clamp 5; Fig.11 The schematic diagram of the water retaining plate near the ridge of a metal roof ridge node waterproof structure of the present application is shown. Fig.11 The bottom and side 32 of the near-ridge water retaining plate 3 are fixedly connected to the metal roof panel 1 .

[0038] Specifically, the metal roof panel 1 can use the commonly used plate type with good wind-resistant performance in the market to ensure the strength and stability of the metal roof panel 1 itself. The metal roof panel 1 adopts a single-sided double water retaining plate design, and is provided with a near-ridge water retaining plate 3 and a far-ridge water retaining plate 4. The near-ridge water retaining plate 3 and the far-ridge water retaining plate 4 have different top structures to adapt to the height change of the ridge flashing plate; a ridge flashing plate 8 is arranged above the near-ridge water retaining plate 3 and the far-ridge water retaining plate 4. The far-ridge water retaining plate 4 is connected to the metal roof panel 1 without nail holes, and is mainly responsible for the fixed connection with the ridge flashing plate 8. At the same time, it also plays the role of the first snow barrier and preventing rainwater from backflowing. The near-ridge water retaining plate 3 mainly plays the role of the second barrier to prevent rainwater from backflowing into the gap between the ridge and the metal roof panel 1. The bottom and side 32 of the near-ridge water retaining plate 3 are both provided with butyl tapes between the roof panel, and the butyl tapes are both connected by nailing and pressing. Figure 2 A schematic structural diagram of a metal roof panel at the ridge of a metal roof ridge node waterproof structure of the present application is shown.

[0039] Furthermore, the top surface 43 of the far ridge water retaining plate 4 is turned outward to facilitate connection with the two side edges of the ridge flashing plate 8 by sewing self-tapping nails 7, ensuring that the nail holes are located outside the water retaining plate to avoid water leakage through the nail holes.

[0040] Further, Fig.12 The schematic diagram of the structure of a U-shaped clamp of a metal roof ridge node waterproof structure of the present application is shown. Fig.12 The far ridge water retaining plate 4 is connected to the metal roof panel 1 without nail holes and is fixed by the screw 51 of the U-shaped clamp 5 to avoid damaging the bottom waterproof layer of the metal roof panel 1.

[0041] Fig. 9 The schematic diagram of the structure of the ridge flashing plate of the metal roof ridge node waterproof structure of the present application is shown. Fig. 9 The top of the ridge flashing plate 8 is provided with a triangular ridge 83, the size of which is calculated based on the deformation, thermal expansion coefficient, maximum length of one side and maximum temperature difference of the metal roof panel 1, to ensure that there is enough adjustment space when the metal roof panel 1 expands and contracts. This prevents the triangular ridge 83 on the top of the ridge flashing plate 8 from being too small and damaged due to uncalculated triangular ridge 83.

[0042] In some embodiments of the present application, a folded flange is provided at the ridge of the metal roof panel 1 .

[0043] In some embodiments of the present application, the far ridge water retaining plate 4 is connected to the metal roof panel 1 without nail holes; it is mainly responsible for the fixed connection with the ridge flashing plate 8, and also serves as the first line of snow protection and rainwater backflow prevention. The bottom and sides of the near ridge water retaining plate 3 are connected to the metal roof panel 1 by nailing and tightening butyl tape.

[0044] In some embodiments of the present application, the top surface 43 of the far ridge water retaining plate 4 is fixedly connected to the two side edges of the ridge flashing plate 8 by sewing self-tapping screws 7, and the holes of the sewing self-tapping screws 7 are arranged on the outer side of the far ridge water retaining plate 4.

[0045] In some embodiments of the present application, the bottom and side 32 of the near-ridge water retaining plate 3 are fixedly connected to the metal roof panel 1 by connecting nails. Specifically, the bottom and side 32 of the near-ridge water retaining plate 3 are fixedly connected to the bottom of the metal roof panel 1 using rivets 6, and the side using sewing self-tapping nails 7. Figure 7 A schematic diagram of the connection structure of the ridge flashing plates overlapped and sewn with self-tapping screws or rivets in a metal roof ridge node waterproof structure of the present application is shown.

[0046] In some embodiments of the present application, the near ridge water retaining plate 3, the far ridge water retaining plate 4, the metal roof panel 1 and the ridge flashing plate 8 are sealed by butyl tape to ensure seamless connection. The butyl tape is set to be a butyl tape with micro beads with a thickness of 4 mm and a width of not less than 30 mm. The butyl tape with micro beads replaces traditional sealants to improve sealing and durability.

[0047] In some embodiments of the present application, the far ridge water retaining plate is designed to have a nail-free connection, that is, a U-shaped clamp 5 connection, and bolt holes are provided on both sides or one side of the U-shaped clamp 5. The bolt holes have internal threads, which are used for screwing the screws into the grooves at the top of the metal roof panel ribs to tighten and fix the ridge water retaining plate to the roof panel.

[0048] In some embodiments of the present application, the overlap of the ridge flashing plate 8 is provided with prefabricated nail holes, including pre-punched circular holes 81 and pre-punched oblong holes 82. The spacing of the prefabricated nail holes is reasonably controlled, and the hole spacing is not greater than 50 mm. In particular, the spacing of the nail holes is reduced at the bend to compact the butyl tape. This prevents the spacing between the connecting nails from being too large, the butyl tape from being compacted, and the ridge flashing plate from being detached and leaking.

[0049] In some embodiments of the present application, Fig. 9The ridge flashing plate 8 is provided with a pre-punched circular hole 81 at one end and a pre-punched oblong hole 82 at the other end. When the ridge flashing plates 8 are overlapped, the circular hole 81 end of the ridge flashing plate is at the bottom and the oblong hole 82 end is at the top, ensuring that the ridge flashing plate 8 can freely expand and contract with temperature changes when overlapped.

[0050] Furthermore, the length of each ridge flashing board 8 matches the pre-punched oblong hole 82 and needs to be determined according to the thermal expansion and contraction deformation of the ridge flashing board 8. It is generally recommended that each ridge flashing board 8 should not exceed 3m in length.

[0051] In some embodiments of the present application, butyl tape is provided at the overlap of the ridge flashing board 8 and is fixed with sewing self-tapping screws 7 or rivets 6 to enhance the connection strength and waterproof effect.

[0052] When implementing one of the embodiments of the present application, first, the near-ridge water retaining plate 3, the far-ridge water retaining plate 4 and the ridge flashing plate 8 are customized according to the size and shape of the metal roof panel 1, the U-shaped clamp 5 with an inner thread is machined, and the required number of rivets 6 and sewing self-tapping screws 7, butyl tape and other materials are prepared.

[0053] Then clean the metal roof panel 1 near the ridge water retaining plate 3 and the far ridge water retaining plate 4, and lay the first butyl tape 2 on the trough 11 and the side 12 of the wave crest of the metal roof panel. Figure 8 A schematic diagram of the structure of a metal roof ridge node waterproof structure of the present application is shown, in which a far ridge water retaining plate 4 is fixed to the crest position of a metal roof panel 1 by a U-shaped clamp 5. Then, the near ridge water retaining plate 3 is installed, and the bottom and sides are fixed respectively by rivets 6 and sewing self-tapping screws 7, and the first butyl tape 2 is compacted and evenly extruded. The far ridge water retaining plate 4 is installed, and it is only fixed to the crest rib groove of the roof panel by the U-shaped clamp 5. The far ridge water retaining plate 4 is connected to the metal roof panel 1 without nail holes. Compact the first butyl tape 2 between the bottom and both sides and the metal roof panel. The top surface 33 of the near ridge water retaining plate 3 is provided with a second butyl tape 21, and the top surface 43 of the far ridge water retaining plate 4 is provided with a third butyl tape 22. Figure 3 A structural schematic diagram showing a metal roof ridge node waterproof structure of the present application in which butyl tape is laid at the ridge water retaining plate position.

[0054] Secondly, the ridge flashing board 8 is processed according to the calculated size of the triangular ridge 83, and overlapped and installed according to the prefabricated nail hole positions. Ensure that the fourth butyl tape 23 is set along the entire length of the overlap between each board, and fixed with sewing self-tapping screws 7 or rivets 6. The ridge flashing board 8 is connected to the top surface 43 of the far ridge water retaining board 4 with sewing self-tapping screws 7, with a spacing of no more than 100mm, and the third butyl tape 22 at the bottom is compacted and evenly extruded. The ridge flashing board 8 is connected to the top surface 33 of the near ridge water retaining board 3 without nailing, and the second butyl tape 21 at the bottom is compacted.

[0055] Finally, after the installation is completed, a comprehensive inspection is carried out to ensure that all joints are tight and seamless, and all butyl tapes are evenly extruded, and then the waterproof performance is tested and accepted.

[0056] The metal roof ridge node waterproof structure provided by the present application has the following positive effects compared with the prior art:

[0057] 1. This application can significantly improve the waterproof performance: by optimizing the ridge node structure design and using high-performance waterproof materials (such as butyl tape), the leakage problem of the ridge node of the traditional metal roof is fundamentally solved.

[0059] 3. This application can simplify the installation process: the prefabricated design reduces on-site processing links and improves installation efficiency and construction quality.
