Description

Technical Field

[0001] This invention relates to an integrated support connector for metal roofing tiles, belonging to the field of metal roofing tile technology. Background Technology

[0002] Metal roofing sheets are a common roofing material, typically made of metal materials such as galvanized steel sheets, aluminum alloy sheets, and copper sheets. They are lightweight, high-strength, corrosion-resistant, and easy to install, and are widely used in roofing systems of various buildings. During actual installation, metal roofing sheets usually need to be fixed to the roof structure using support connectors to ensure their stability, waterproofing, and wind uplift resistance.

[0003] Existing metal roof tile connectors commonly have simple structures in practical applications and often lack effective waterproofing designs, making them prone to water seepage in windy and rainy weather, which affects the sealing performance and service life of the roof.

[0004] In addition, existing connectors mostly adopt a multi-part assembly method, which requires the alignment and fixing of multiple parts during installation. This not only results in low construction efficiency, but also makes it easy for assembly errors to lead to weak connections, thereby affecting the stability and safety of the overall structure.

[0005] Chinese patent document CN202223286024.7 discloses a sturdy metal tile connector, including a fixing block, a groove at the bottom of the fixing block, a slider slidably connected to the inner wall of the groove, a connecting block fixedly connected to the bottom of the slider, a rotating block rotatably connected inside the connecting block, a support block fixedly connected to the bottom of the rotating block, a fixing plate fixedly connected to one side of the support block, a sliding rod slidably connected to the inner wall of the fixing plate, a pressing plate fixedly connected to the top of the sliding rod, and a tension spring sleeved on the outer wall of the sliding rod, the tension spring being located between the pressing plate and the fixing plate on their respective sides. Summary of the Invention

[0006] The technical problem to be solved by this invention is that metal tile roofing is cumbersome to install, has insufficient connection strength, is prone to leakage, and has limited adaptability to different tile types.

[0007] The present invention proposes a technical solution to solve the above-mentioned technical problems as follows: an integrated support connector for metal tiles, comprising an integrally bent connecting piece, two inner folded pieces and two outer folded pieces, wherein the inner folded pieces are formed by folding the left and right sides of the connecting piece from bottom to top and inward, and the outer folded pieces are formed by folding the left and right sides of the inner folded pieces from bottom to top and outward. The connecting piece has two upward-protruding inner ribs in the middle, which are arranged in the front-back direction; The inner fold is divided into a front section, a middle section, and a rear section. The front section is attached to the top of the connecting piece, the middle section is set obliquely inward, and the rear section is parallel to the connecting piece and forms a cavity to accommodate the metal tile. There is a gap between the top of the inner convex rib and the rear section of the inner fold. The outer fold is divided into a front section, a middle section, and a rear section. The front section of the outer fold is attached to the top of the rear section of the inner fold. The middle section of the outer fold is set diagonally outward and attached to the top of the middle section of the inner fold. The inner side of the rear section of the outer fold is attached to the top of the front section of the inner fold. The outer side of the rear section of the outer fold has a waterproof flange that folds inward from bottom to top. Near the waterproof flange, the rear section of the outer fold has an outwardly protruding rib that is set in the front-back direction and protrudes upward. The back sides of the connecting piece, inner fold piece, and outer fold piece are all folded upwards to form an upper folded edge, while the front sides of the connecting piece, inner fold piece, and outer fold piece are all folded downwards to form a lower folded edge.

[0008] To further explain, the connection between the front and middle sections of the inner fold is an obtuse angle, the connection between the middle and rear sections of the inner fold is an obtuse angle, the connection between the front and middle sections of the outer fold is an obtuse angle, and the connection between the middle and rear sections of the outer fold is an obtuse angle, with the obtuse angle being - degrees.

[0009] To further explain, the connection between the rear section of the outer fold and the waterproof flange forms an acute angle.

[0010] To further explain, the bottom of the inner and outer flaps extends and fits against the lower flange, and the two inner flaps and two outer flaps located on the lower flange have grooves in the middle.

[0011] To further explain, the tops of the inner and outer flaps extend and fit against the upper flange, and the waterproof flange also extends to the upper flange.

[0012] To further explain, the inner curvature of the inner convex rib is consistent with that of the outer convex rib.

[0013] To further explain, the middle sections of both the inner and outer folds are located on one side of the inner convex rib.

[0014] To further explain, a right angle is formed between the upper flange and the outer fold; an included angle is formed between the connecting piece and the lower flange.

[0015] This invention has positive effects: (1) By setting upward-protruding inner and outer ribs, and in conjunction with the cavity structure formed between the inner fold and the connecting piece, the present invention significantly enhances the longitudinal bending resistance and load-bearing strength of the connector as a whole. Each bending part has a specific angle, which further optimizes the mechanical properties and can effectively resist external forces such as wind load and snow load, ensuring that the metal tile is firm and stable after installation and is not easily deformed or loosened; (2) The uniquely designed waterproof flange of this invention, and the acute angle formed between the outer fold and the waterproof flange, can effectively guide rainwater outward and prevent rainwater from flowing back along the connector or seeping into the roof system. Combined with the integrated structural design, it reduces seams and leakage points, and improves the overall waterproof sealing and durability of the roof; (3) The overall shape and multi-layer bending design of the connecting piece of the present invention enable it to better adapt to metal tile types of different specifications and different crest heights, ensuring that the connecting parts fit tightly. The integrated design also facilitates continuous laying or customized production according to actual roof requirements, improving the product's applicability and engineering practicality.
