Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, specifically to a stainless steel roof waterproofing structure at the ridge. Background Technology

[0002] Currently, in the construction of curved metal roofs, the drainage boards of the roofs are mostly made of continuous stainless steel plates welded together, which gives the continuous board surface a good waterproofing and flashing effect.

[0003] However, numerous technical challenges exist at the ridge joint: improper joint treatment leading to inadequate sealing, insufficient drainage slope causing water accumulation, and the lack of a waterproof reinforcement layer all contribute to potential leaks. Current technology typically involves cutting stainless steel plates along the ridge's contours and fixing them with adhesive or rivets, then covering them with a metal cover plate. This approach has significant drawbacks: firstly, it lacks meticulous treatment of the roof drainage board at the ridge joint, making the connection prone to leaks; secondly, material aging and deformation over time exacerbates the risk of leakage; and thirdly, this construction method may create weak points in the roof panels, making them susceptible to structural damage under strong wind loads. Furthermore, existing technology is significantly inadequate in terms of the connection method between the waterproof cover plate and the inner roof panel, sealing treatment, and waterproof reinforcement measures, failing to meet the stringent requirements of modern building roof waterproofing performance.

[0004] Therefore, how to improve the seepage prevention effect between the drainage board at the ridge and the roof, while ensuring structural stability and durability, has become a problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] This utility model provides a stainless steel roof waterproofing structure at the ridge, including secondary purlins arranged on both sides of the ridge line and roof inner panels laid on the corresponding secondary purlins for roof drainage. A waterproof cover plate is provided between the roof inner panels located on both sides of the ridge line, spanning the ridge line and with its two ends connected and fixed to the corresponding roof inner panels.

[0007] Furthermore, the inner roof panel has a corrugated structure on a cross section parallel to the ridge line, and the waterproof cover plate has a flanged portion facing outwards from the top of the inner roof panel when it is located at a high position of the inner roof panel, and is connected and fixed to the inner roof panel through the flanged portion.

[0008] Furthermore, the waterproof cover is sealed by adhesive when it is located at the lower surface of the inner roof panel.

[0009] Furthermore, the inner side of the waterproof cover plate is also provided with a foam strip and waterproof material at the sealant bonding area.

[0010] Furthermore, the inner roof panel is vertically bent upward at the end near the ridge line to form an arc-shaped section for waterproofing.

[0011] Furthermore, the inner roof panel is provided with a first fixing seat for installing the aluminum alloy frame, and the outer roof panel is installed on the aluminum alloy frame by fasteners.

[0012] Furthermore, the gaps between the roof panels on both sides of the ridge line are filled and sealed with foam strips, and sealant is also provided above the foam strips.

Detailed Implementation

[0018] This application proposes a waterproof structure for a stainless steel roof at the ridge, comprising secondary purlins 1 located on both sides of the ridge line and roof inner panels 2 laid on the corresponding secondary purlins 1 for roof drainage. A waterproof cover plate 3 is provided between the roof inner panels 2 located on both sides of the ridge line, spanning the ridge line and with its two ends connected and fixed to the corresponding roof inner panels 2. The secondary purlins 1 can be made of galvanized steel with a C-shaped or Z-shaped cross-section and are connected and fixed to the main purlins by self-tapping screws. The roof inner panel 2 is preferably made of 0.4-1.2mm thick stainless steel plate, laid continuously along the drainage direction. Longitudinal overlaps can be sealed using interlocking connections or welding. The waterproof cover plate 3 can be made of 1.5-3mm thick stainless steel plate, with its width extending 150-300mm beyond each side of the ridge line. Its ends are double-fixed to the roof inner panel 2 using stainless steel blind rivets or structural adhesive. A 10-15mm arc-shaped bulge can be added to the center of the waterproof cover plate 3 to enhance structural rigidity. This structure, through the continuous coverage design of the waterproof cover plate 3 across the ridge line, effectively solves the leakage problem caused by improper treatment of traditional ridge joints. The rigid connection between the waterproof cover plate 3 and the roof inner panels 2 on both sides forms a complete drainage channel, avoiding gaps caused by wind pressure deformation. Compared to the simple metal baffle and covering layer method in existing technologies, this solution, through the direct fixing of the integral waterproof cover plate 3 to the drainage board, significantly improves the sealing reliability and structural stability of the joints.

[0019] In this embodiment, the inner roof panel 2 has a corrugated structure on a cross-section parallel to the ridge line. The waterproof cover plate 3, when positioned high above the inner roof panel 2, has a flange 4 extending outwards from the top surface of the inner roof panel 2, and is connected and fixed to the inner roof panel 2 via the flange 4. The inner roof panel 2 is a corrugated plate with a corrugated structure, specifically an aluminum-magnesium-manganese alloy plate. The corrugated structure can be formed through a continuous bending process. The flange 4 can be implemented in the following ways: firstly, by stamping to form an L-shaped flange matching the top shape of the inner roof panel 2; secondly, by segmented welding to connect the prefabricated flange edge to the waterproof cover plate 3 body. The connection and fixing methods include: using stainless steel blind rivets for intermittent fixing, or using laser welding to form a continuous sealed weld. This solution mainly uses self-tapping screws for installation and fixing. This technical solution forms multiple drainage channels through the corrugated structure, effectively dispersing the water collection in the ridge line area. The connection between the flanged part 4 and the top of the board forms a double waterproof barrier. The flanged part 4 can prevent rainwater from seeping in laterally and also enhance the connection strength between the inner roof board 2 and the waterproof cover plate 3.

[0020] In this embodiment, the waterproof cover plate 3 is bonded and sealed with sealant 13 when it is located at the lower surface of the inner roof panel 2. The sealant 13 can be made of materials with good weather resistance and adhesion, such as polyurethane sealant, silicone sealant, or polysulfide sealant, to ensure sufficient sealing effect and durability. Before applying the sealant 13, the contact surfaces between the inner roof panel 2 and the waterproof cover plate 3 need to be cleaned to remove oil and dust to improve bonding strength. The sealant can be applied by dot application or continuous application, with continuous application providing a better sealing effect. This technical solution effectively solves the leakage problem at the ridge caused by improper joint treatment by using sealant 13 to bond and seal the lower surface of the inner roof panel 2. Compared with existing technologies, the application of sealant 13 not only fills the joint gaps but also has good elastic deformation capacity, which can adapt to the expansion and contraction deformation of the roof due to temperature changes, thus maintaining a long-term sealing effect.

[0021] In this embodiment, a foaming strip 5 and a waterproof material 6 are further provided on the inner side of the waterproof cover plate 3 at the bonding point of the sealant 13. The waterproof material 6 can be made of waterproof roll material, waterproof coating, or waterproof membrane, etc. In this solution, the waterproof material 6 is EVA waterproof cotton. By adding the waterproof material 6 at the bonding point of the sealant 13, a double waterproof barrier can be formed. When the sealant 13 ages or cracks due to long-term use, the waterproof material 6 can still effectively prevent moisture penetration.

[0022] In this embodiment, the inner roof panel 2 is vertically bent upward at the end near the ridge line to form an arc-shaped segment 7 for waterproofing; the technical solution effectively solves the leakage problem at the ridge joint by bending the end of the inner roof panel 2 to form the arc-shaped segment 7; the arc-shaped structure can guide water flow along a predetermined path to avoid water accumulation; the upward bending design increases the length of the waterproof path, and even if the sealant 13 ages and fails, it can still prevent water penetration through a physical barrier.

[0023] In this embodiment, a first fixing seat 10 for installing an aluminum alloy frame 8 is provided on the inner roof panel 2. The outer roof panel 9 is installed on the aluminum alloy frame 8 via fasteners 11. The outer roof panel 9 is a 3mm thick fluorocarbon-coated hyperbolic aluminum plate. This design achieves a stable connection between the aluminum alloy frame 8 and the inner roof panel 2 through the fixing seat, thereby enabling the aluminum alloy frame 8 to form a connection with the secondary purlins 1. The aluminum alloy frame 8 is then fixed to the secondary purlins 1, and the outer roof panel 9 is installed on the aluminum alloy frame 8 mainly via fasteners 11, making the outer roof panel 9 more securely installed. The rigid support of the aluminum alloy frame 8 can distribute wind loads, preventing the outer roof panel 9 from deforming and cracking due to wind force. The cavity structure formed by the outer roof panel 9 and the inner panel is conducive to drainage and ventilation, reducing condensation accumulation.

[0024] In this embodiment, the gaps between the roof panels 9 on both sides of the ridge line are filled and sealed with foam strips 5, and sealant 13 is also provided on top of the foam strips 5. The foam strips 5 are polyurethane materials with expansion properties, which can form a closed-cell structure after curing, and have excellent sealing and waterproof performance. During implementation, the foam can be injected into the gaps between the roof panels 9 through a caulking gun. After it expands and cures, it can tightly fill the gaps and form a waterproof barrier. The application of the foam can be carried out after the roof panels 9 are installed, which is simple to operate and does not affect the overall construction progress. The sealant 13 is also provided on top of the foam strips 5, which further improves the waterproof effect at the ridge. This technical solution, by filling the gaps between the roof panels 9 with foam strips 5 and sealing them with sealant 13, can effectively prevent rainwater penetration and enhance the overall sealing of the roof. The elasticity of the foam strips 5 allows them to adapt to the thermal expansion and contraction of the roof panels, avoiding cracking caused by temperature changes. In addition, the lightweight nature of foam strip 5 will not increase the roof load, and its weather resistance and anti-aging properties can ensure long-term waterproofing.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
