[0002] In coastal areas and highly corrosive environments, metal roof decorative panel systems face severe challenges: Impact of strong typhoons: Traditional metal roofs lack wind resistance, connectors are prone to loosening and falling off, leading to structural failure; Highly corrosive environments: Corrosive media such as sea salt and acid rain accelerate the rust of metal components, shortening their service life and making maintenance difficult; Traditional decorative panel systems are complex to assemble, and local damage requires overall demolition, resulting in high maintenance costs and structural stability; the connection method between the secondary purlins and the main purlins is single, making it difficult to adapt to complex loads.

[0003] In the prior art, some systems use welding or simple bolt connections, but have poor fatigue resistance; some systems use stainless steel materials, but they are expensive and difficult to process.

[0004] Therefore, in view of the above technical problems, it is necessary to propose a metal roof decorative panel system for strong typhoon and strong corrosion areas. Summary of the invention

[0005] The purpose of the present invention is to provide a metal roof decorative panel system for areas with strong typhoons and strong corrosion, so as to solve the problem of wind-resistant roof decorative panels of existing metal roofs in areas with strong typhoons and strong corrosion.

[0006] To achieve the above object, the present invention provides the following technical solutions: A metal roof decorative panel system for strong typhoon and strong corrosion areas comprises a grille decorative strip, a frame, an upper layer purlin 1, an upper layer purlin 2, an upper layer main purlin and a steel round tube support. The upper layer main purlin is connected to the steel round tube support through a main purlin condition, the upper layer purlin 2 is connected to the upper layer main purlin, the upper layer purlin 1 is connected to the upper layer purlin 2, the frame is connected to the upper layer purlin 1, and the grille decorative strip 1 is fixed to the frame by screws.

[0007] Preferably, the grille decorative strip is assembled from a plurality of decorative panels.

[0011] Preferably, the two first purlin connectors are connected to the upper portion of the steel round tube support via screws.

[0012] Preferably, the two second purlin connectors are clamped and connected to the upper main purlin 5 by bolts.

[0013] Preferably, a connecting groove for cooperating and connecting with a flange ring of a steel round tube support is provided at the lower portion of the first purlin connecting member.

[0014] Preferably, the grille decorative strips, the frame, the upper purlin one, the upper purlin two, and the upper main purlin are all made of aluminum alloy components or steel components, and the surfaces are all fluorocarbon sprayed.

[0043] The aluminum alloy grille decorative strip 1 is effectively connected to the aluminum alloy frame 2 by plugging and snapping and assembled into an assembled component, ensuring that each component is firmly connected and the overall structure is stable and reliable, capable of withstanding the load and external force of a strong typhoon, and ensuring the structural safety during use.

[0044] After the surface layer of this system is assembled, a double-channel connection is adopted between the sub-frame and the supporting purlin to resist strong typhoons. First, a pressure block is used to pass the bolts to reliably connect the sub-frame 2 with the upper layer purlin 1 3, and secondly, the sub-frame is hooked with the upper layer purlin 1 3 by using a U-shaped hook design. Even if the bolts are loose, the sub-frame and the purlin cannot be separated. Strict structural mechanics calculations and simulation tests are carried out to ensure that each component is firmly connected and the overall structure is stable and reliable.

[0045] This system takes into account the special-shaped structure between the purlin and the main structure. A disc is set on the top of the steel round tube support 8. The main purlin aluminum alloy connectors 6&7 are connected with bolts and discs in the form of hoops to achieve multi-angle adjustment in the XY axis plane. The adjustment on the construction site is simple and can be directly assembled quickly, which effectively speeds up the overall project progress. While meeting the stress requirements, it also meets the process structure and functional requirements.

[0046] The grille decorative strips, sub-frames and purlins of the supporting system of this system are all made of aluminum alloy components. The surface is fluorocarbon sprayed to resist chemical corrosion, atmospheric corrosion and excellent weather resistance, and can resist UV aging and adapt to temperature changes. In addition, the fluorocarbon spray treatment of aluminum alloy has good adhesion, mechanical properties and self-cleaning properties, which can effectively resist the erosion of chemical substances in highly corrosive areas and prevent the material from being corroded.

[0047] Installation process, the steel round tube support 6 is fixed to the main structure 15; the upper main purlin 5 is connected to the steel round tube support 6 through the main purlin condition 7; the upper layer purlin 2 4 is bolted to the upper layer main purlin 5 through the angle steel; the upper layer purlin 1 3 is vertically connected to the upper layer purlin 2 4; the frame 2 is fixed to the upper layer purlin 1 3 through the pressure block bolts; the grille decorative strip 1 is assembled and fixed to the frame 2 by screws.

[0059] Frame and secondary purlin: Frame 2 is fixed to secondary purlin 3 by means of pressure blocks and M10 stainless steel bolts, with a spacing of 250mm. The depth of the U-shaped hook is increased to 30mm to enhance the pull-out resistance.

[0060] Enhanced corrosion protection: All bolted joints are pre-coated with PTFE tape to prevent galvanic corrosion.

[0061] A stainless steel flange is welded to the bottom of the steel round tube support 6, which is fixed to the concrete foundation by chemical anchor bolts, and the interface is filled with epoxy resin mortar.

[0062] Corrosion verification: Salt spray test (ASTMB117) shows that the system components can withstand salt spray for 1500 hours, and the fluorocarbon coating has no blistering or peeling.

[0063] Comparison of embodiments: According to the analysis of the embodiments, the first embodiment adopts the lightweight design of aluminum alloy and the double-channel connection structure, taking into account both wind resistance and economy, and is suitable for areas with frequent typhoons. The second embodiment adopts all stainless steel materials and multiple anti-corrosion measures to meet the needs of strong corrosive environments, but the cost is relatively high.
