Description

Technical Field

[0001] This utility model belongs to the field of coated metal tile technology, and specifically relates to a coated metal tile. Background Technology

[0002] Film-coated metal roofing sheets are composite roofing materials that integrate a metal substrate with a high-performance polymer coating. Their core strength lies in combining the structural strength of metal with the durable waterproofing performance of flexible materials. They typically use thin metal sheets such as galvanized steel or aluminum-magnesium-manganese steel as the base structural layer, then firmly bond a layer of highly weather-resistant plastic film, such as PVDF (polyvinylidene fluoride) or PET, to its outer surface through a high-temperature hot-pressing composite process. This coating not only gives the roofing sheet rich colors and textures but also plays a crucial protective role, resisting long-term UV radiation, rain erosion, temperature changes, and chemical pollution, thus significantly delaying the corrosion and aging of the metal substrate itself. This design makes film-coated metal roofing sheets a modern roofing solution that combines aesthetic appeal with long-term protective functionality.

[0003] Existing metal roofing tiles, especially after adjacent tiles are spliced ​​together, inevitably create overlapping gaps at the joints, which constitute weak points in the roof waterproofing system. To achieve effective waterproofing and sealing, additional independent waterproofing components must be used for secondary treatment during construction, such as laying specialized waterproofing sealant strips on-site, applying elastic waterproofing coatings, or installing polymer waterproofing covers. This reliance on subsequently added waterproofing components not only increases material costs and complicates construction procedures but also places high demands on the operational standards of construction workers. In actual use, due to factors such as temperature changes, wind loads, and structural deformation, these added waterproofing components are prone to peeling, aging, or displacement from the metal tile body, leading to seal failure and leakage problems. Once leakage occurs, repair work is extremely cumbersome, requiring precise location of the leak point and resealing, resulting in high maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a coated metal tile to solve the technical problems of low sealing reliability, complex construction and high overall cost caused by the reliance on additional waterproof components at the joint of coated metal tiles in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coated metal tile includes: a coated metal tile body, the coated metal tile body including a metal plate, the front and outer walls of the metal plate being covered with a flexible waterproof membrane, ribs being provided on both sides of the coated metal tile body, both ribs being inclined upwards, a first connecting buckle and a second connecting buckle being provided at the ends of the two ribs respectively, the second connecting buckle having a groove adapted to the first connecting buckle, and a sealing mechanism being provided on the second connecting buckle;

[0007] The sealing mechanism includes a baffle fixedly mounted on the outer wall of the second connecting buckle. The baffle is L-shaped and has an insert block at its bottom. The end of the insert block is arc-shaped. A sealing groove adapted to the insert block is opened on the outer wall of the rib plate near the bottom of the insert block. The insert block is inserted into the sealing groove.

[0008] Preferably, a flexible waterproof strip is fixedly provided on the outer wall of the baffle, and the flexible waterproof strip is bonded and fixed between the outer wall of the side of the baffle near the rib and the outer wall of the rib.

[0009] Preferably, a first buffer pad is fixedly provided on the outer wall of the first connecting buckle, the first buffer pad being U-shaped and covering the outer side of the first connecting buckle, the second connecting buckle being U-shaped, and two second buffer pads being fixedly provided on the inner wall of the second connecting buckle.

[0010] Preferably, the two second cushioning pads are respectively fixedly disposed at the inner top and inner bottom of the second connecting buckle.

[0011] Preferably, the first and second cushioning pads are made of closed-cell polyethylene foam or EPDM rubber foam, and pressure-sensitive adhesive is provided on both the first and second cushioning pads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By using the first and second connecting buckles, two coated metal tile bodies are connected. The first and second buffer pads work together to form a sealing structure at the joint of the metal tiles, achieving a tight fit and multiple seals when adjacent metal tiles are connected. This effectively eliminates the gaps produced by traditional connection methods. The insertion of the plug and the sealing groove form the first physical barrier. Combined with the secondary protection formed by the baffle and the flexible waterproof strip, a reliable waterproof system is constructed. At the same time, the buffer pads not only ensure the airtightness and watertightness of the connection, but also provide good heat insulation and structural cushioning. The overall structure has a high degree of integration, which greatly simplifies the on-site construction process, reduces the reliance on additional waterproof components, and significantly improves the waterproof reliability, construction efficiency, and long-term stability of the roofing system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1 - Figure 6 As shown, a coated metal tile includes: a coated metal tile body 1, the coated metal tile body 1 includes a metal plate 2, the front and outer wall of the metal plate 2 are covered with a flexible waterproof membrane 3, ribs 4 are provided on both sides of the coated metal tile body 1, the two ribs 4 are inclined upwards, the ends of the two ribs 4 are respectively provided with a first connecting buckle 5 and a second connecting buckle 6, the second connecting buckle 6 is provided with a groove adapted to the first connecting buckle 5, and a sealing mechanism is provided on the second connecting buckle 6;

[0024] The sealing mechanism includes a baffle 9 fixedly installed on the outer wall of the second connecting buckle 6. The baffle 9 is L-shaped and has an insert 10 at the bottom. The end of the insert 10 is arc-shaped. A sealing groove 11 adapted to the insert 10 is opened on the outer wall of the rib plate 4 near the bottom of the insert 10. The insert 10 is inserted into the sealing groove 11.

[0025] A flexible waterproof strip 12 is fixedly installed on the outer wall of the baffle 9. The flexible waterproof strip 12 is bonded and fixed between the outer wall of the side of the rib 4 and the outer wall of the rib 4.

[0026] As can be seen from the above, this embodiment achieves multiple waterproof seals through the sealing mechanism set on the second connecting buckle 6. When two adjacent coated metal tiles are connected, the insert 10 on the second connecting buckle 6 is precisely inserted into the sealing groove 11 on the corresponding rib plate 4 of the other tile, forming the first mechanical sealing barrier. The arc-shaped design of the end of the insert 10 ensures the smoothness of the insertion process and the tightness of the sealing contact. At the same time, the L-shaped baffle 9 fixed to the outer wall of the second connecting buckle 6 can effectively block lateral rainwater in its vertical part, while the horizontal part provides a stable mounting base for the flexible waterproof strip 12. The flexible waterproof strip 12 is bonded and fixed to the outer wall of the rib plate 4 on its side near the rib plate 4, forming a second flexible waterproof layer covering the mechanical connection part. This sealing method combining insertion and bonding significantly improves the overall waterproof reliability and durability of the connection.

[0027] Example 2:

[0028] A first buffer pad 7 is fixedly provided on the outer side wall of the first connecting buckle 5. The first buffer pad 7 is U-shaped and covers the outer side of the first connecting buckle 5. The second connecting buckle 6 is U-shaped and two second buffer pads 8 are fixedly provided on the inner side wall of the second connecting buckle 6.

[0029] Two second cushioning pads 8 are respectively fixedly installed at the inner top and inner bottom of the second connecting buckle 6;

[0030] The first cushioning pad 7 and the second cushioning pad 8 can be made of closed-cell polyethylene foam or EPDM rubber foam, and pressure-sensitive adhesive is provided on both the first cushioning pad 7 and the second cushioning pad 8.

[0031] As can be seen from the above, the buffer pads added to the first connecting buckle 5 and the second connecting buckle 6 in this embodiment further optimize the connection performance. The first buffer pad 7, which is U-shaped and covers the outside of the first connecting buckle 5, cooperates with the two second buffer pads 8 set at the top and bottom of the second connecting buckle 6. When the first connecting buckle 5 is inserted into the groove of the second connecting buckle 6 to achieve a meshing connection, these buffer pads are compressed between the contact surfaces, effectively filling the assembly gaps between the metal components, eliminating gaps that may be caused by processing tolerances or deformation, thereby ensuring the airtightness and watertightness of the connection. The selected closed-cell polyethylene foam or EPDM rubber foam material not only gives it excellent elastic recovery ability to cope with long-term compression, but its inherent closed-cell structure also provides additional heat insulation effect. In addition, the pressure-sensitive adhesive layer pre-set on the first buffer pad 7 and the second buffer pad 8 allows for quick positioning and temporary fixation during installation, greatly simplifying the construction process and improving installation efficiency and quality.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
