[0029] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0030] Please refer to Figures 1-6 As shown, the technical solution adopted by the present invention is: a multifunctional aluminum roof tile, comprising an outer roof 1 and an inner roof 2 arranged in sequence from top to bottom; a polyurethane layer 3 is formed between the outer roof 1 and the inner roof 2 by foaming; a plurality of bosses 11 are uniformly provided along the length direction of the outer roof 1; a water guide trough 12 is formed between two adjacent bosses 11;

[0031] One end of the outer roof 1 is bent in sequence to form a first U-shaped groove 13 and a first protrusion 14 based on the height of the water guide groove 12; the other end of the outer roof 1 is bent in sequence to form a second protrusion 15 and a second U-shaped groove 16 based on the height of the water guide groove 12; the first U-shaped groove 13 and the second protrusion 15 are adapted to each other; the first protrusion 14 and the second U-shaped groove 16 are adapted to each other;

[0032] When two roof tiles are connected, the first protrusion 14 of one roof tile fits into the second U-shaped groove 16 of the other roof tile, and the second protrusion 15 fits into the first U-shaped groove 13; the connecting ends of the two roof tiles fit together and form a water guide trough 12.

[0033] As can be seen from the above description, the outer roof 1 and the inner roof 2 are connected by foaming, and a polyurethane roof 3 is formed, which makes the roof tiles have good thermal insulation functions. At the same time, it also simplifies the original method of connecting the outer roof 1 and the inner roof 2 through I-beams, making installation more convenient. In addition, by providing a first U-shaped groove 13, a first protrusion 14, a second protrusion 15, and a second U-shaped groove 16 at both ends of the outer roof 1, a method of matching the protrusions with the U-shaped groove is adopted to achieve a quick connection between the two roof tiles. The connection surface between the two roof tiles is larger, which can increase the connection strength between the two roof tiles, and the quality requirements of the connection part are lower than the original clamping method. At the same time, the connection part between the two roof tiles forms a water guide groove 12. Therefore, after all the roof tiles are installed, they have better integrity and are more beautiful.

[0034] Preferably, the end of the first protrusion 14 is bent upward by 10° to 15°; a notch 4 is formed between the end of the first protrusion 14 and the inner roof 2; a third protrusion 5 is provided on the plane at the lower end of the second U-shaped groove 16; when the two roof tiles are connected, the third protrusion 5 fits into the notch 4.

[0035] As can be seen from the above description, when two roof tiles are connected, since the lower end surface of the second U-shaped groove 16 has a certain elasticity, the third protrusion 5 of one roof tile can be embedded in the groove 4 of the other roof tile, and the third protrusion 5 fits with the groove 4; through the above arrangement, it is not easy for misalignment to occur between two adjacent roof tiles, further ensuring the stability of the connection between the two roof tiles.

[0036] Preferably, an angle is formed between a plane at the upper end and a plane at the lower end of the opening of the first U-shaped groove 13 , and the angle is 15° to 30°.

[0037] From the above description, it can be seen that when two roof tiles are connected, since the opening of the first U-shaped groove 13 is provided with a certain angle, the second protrusion 15 of the other roof tile can be more easily aligned with the first U-shaped groove 13, making it convenient for the operator to quickly complete the connection operation.

[0038] Preferably, the surface of the exterior roof 1 is provided with an anti-rust layer 17 , and the anti-rust layer 17 is a coating of anti-corrosion material sprayed on the surface of the exterior roof 1 .

[0039] From the above description, it can be seen that providing an anti-rust layer 17 on the surface of the outer roof 1 can further enhance the anti-rust effect of the roofing tile 1, so that the roofing tile can be used in an environment with high acidity and alkalinity, and has a wide range of applicable scenarios.

[0040] Preferably, the outer roof 1 is a plate formed by integrally processing a thin aluminum plate, and the thickness of the outer roof 1 is 0.1 to 0.3 mm.

[0041] From the above description, it can be seen that using thin aluminum plate as the base material has a certain anti-rust effect. At the same time, it has the advantages of being lightweight, durable, beautiful and recyclable.

[0042] like Figures 7 and 8 As shown, preferably, when the outer roof 1 is used as an end tile, one end thereof is flat, and the other end is provided with a first U-shaped groove 13 and a first protrusion 14 or a second protrusion 15 and a second U-shaped groove 16 .

[0043] As can be seen from the above description, when the roofing tile is the outermost tile, one end of its outer roof surface 1 is flat, and the other end is selected based on the end surface structure of the adjacent roofing tile. When the end surface of the adjacent roofing tile has a first U-shaped groove 13 and a first protrusion 14, the outermost roofing tile is provided with a corresponding second protrusion 15 and second U-shaped groove 16. Conversely, when the end surface of the adjacent roofing tile has a second protrusion 15 and a second U-shaped groove 16, the outermost roofing tile is provided with a corresponding first U-shaped groove 13 and first protrusion 14.

[0044] The working principle of the utility model is as follows: when installing roof tiles, the outermost roof tile can be fixed first; then according to the end surface structure of the outermost roof tile on the inner side, the corresponding roof tile can be selected for connection;

[0045] Taking the inner end face of the outermost roof tile as the first U-shaped groove 13 and the first protrusion 14 as an example, before connecting another roof tile, align the second protrusion 15 of the roof tile to be connected with the first U-shaped groove 13. Since the opening of the first U-shaped groove 13 has an upward angle, the operator can quickly push the second protrusion 15 into the first U-shaped groove 13. At the same time, the first protrusion 14 also fits into the second U-shaped groove 16; after the two roof tiles are connected, the third protrusion 5 is located in the groove 4, which improves the stability of the connection between the two roof tiles; fix the connected roof tiles, and continue to install the roof tiles to be connected according to the above steps until the coverage area is reached.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
