Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction, and more specifically, to a roofing tile. Background Technology
[0002] Resin tiles, also known as synthetic resin tiles, are a new type of roofing tile made from resin substrates such as PVC, PP, FRP, and APVC through co-extrusion technology. Due to their light weight, high strength, good waterproof performance, and corrosion resistance, they are widely used in the construction industry. Common shapes of resin tiles are curved or flat. However, during use, it has been found that when resin tiles are spliced, the seal is poor, allowing rainwater to easily seep down through the gaps between the two tiles, reducing the waterproof effect and significantly impacting usability.
[0003] Therefore, there is an urgent need for a type of roofing tile with good waterproof performance. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a roofing tile with good waterproof effect. The tile increases the waterproof effect and extends the service life by setting a double-layer sealed waterproof structure on both sides of the tile body.
[0005] To solve the above-mentioned technical problems, this utility model provides the following solution:
[0006] A roofing tile includes a tile body, one end of which has a first overlapping portion extending outward, and the other end of which has a second overlapping portion corresponding to the first overlapping portion. The end of the first overlapping portion has a groove, and a limiting strip is provided below the first overlapping portion. The second overlapping portion has a sealing strip that cooperates with the limiting strip, and the end of the second overlapping portion has a strip-shaped sealing block that cooperates with the groove. A first waterproof groove is formed between the tile body and the sealing strip, and a second waterproof groove is formed between the sealing strip and the sealing block.
[0007] A further technical solution involves providing several longitudinally arranged water-guiding grooves on the upper surface of the tile body. During rain, these grooves quickly channel rainwater downwards, achieving a drainage effect.
[0008] In a further technical solution, the tile body is flat.
[0009] A further technical solution involves an inclined sealing strip, tilted towards the direction of engagement with the limiting strip, with an angle of 45-90° to the horizontal plane. During installation, the inclined sealing strip can engage more tightly with the limiting strip, improving sealing performance.
[0010] A further technical solution is that the sealing strip is provided with an elastic element, which is a soft rubber strip. By providing the soft rubber strip, the sealing strip and the limiting strip can be engaged more tightly, thereby improving the sealing performance.
[0011] A further technical solution is that the sealing strip is an elastic sealing strip, which has a certain degree of elasticity and can be more tightly connected with the limiting strip when spliced together, thus improving the sealing performance.
[0012] A further technical solution is that the tile is integrally formed. Beneficial effects
[0013] Compared with the prior art, the present invention has the following significant advantages:
[0014] 1. This utility model improves the sealing of the tiles during splicing by setting double-layer sealed waterproof grooves on both sides of the tiles, effectively preventing rainwater leakage, greatly improving the waterproof effect of the tiles, and extending the service life of the tiles.
[0015] 2. This utility model has a simple structure. When splicing, the first and second overlapping parts of the two tiles can be directly spliced and snapped together, which is convenient for quick assembly and disassembly. Even if any tile is damaged after long-term use, it is easy to remove and replace. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example
[0024] like Figure 1-2As shown, a roofing tile includes a tile body 1. One end of the tile body 1 is provided with a first overlapping portion 2 extending outward, and the other end of the tile body is provided with a second overlapping portion 3 corresponding to the first overlapping portion. The end of the first overlapping portion 2 is provided with a groove 4, and a limiting strip 5 is provided below the first overlapping portion 2. A sealing strip 6 that cooperates with the limiting strip 5 is provided on the second overlapping portion. The end of the second overlapping portion 3 is provided with a strip-shaped sealing block 7 that cooperates with the groove 4. A first waterproof groove 8 is formed between the tile body 1 and the sealing strip 6, and a second waterproof groove 9 is formed between the sealing strip 6 and the sealing block 7.
[0025] The upper surface of the tile body 1 is provided with several longitudinally arranged water-guiding grooves 10. When it rains, the water-guiding grooves can quickly guide rainwater downwards, achieving a rapid drainage effect. The water-guiding grooves can be arranged at equal or unequal intervals, mainly to achieve rapid drainage and prevent water accumulation.
[0026] The tile body 1 is flat.
[0027] The sealing strip 6 is inclined, tilting towards the direction of engagement with the limiting strip. The tilt angle is 45-90° with the horizontal plane; 90° is considered vertical, and less than 90° is considered inclined. Figure 3-4 As shown, during installation, the inclined sealing strip can engage more tightly with the limiting strip, improving the sealing performance.
[0028] The sealing strip 6 is provided with an elastic element, which is a soft rubber strip. By providing the soft rubber strip, the sealing strip and the limiting strip can be engaged more tightly, thereby improving the sealing performance.
[0029] The sealing strip 6 is an elastic sealing strip. The sealing strip itself has a certain degree of elasticity, and when spliced with the limiting strip, it can be more tightly sealed, thus improving the sealing performance.
[0030] The tiles are integrally molded. A polymer resin material can be used as the base material, and the tiles are extruded using co-extrusion technology.
[0031] The method of using this utility model is as follows:
[0032] like Figure 4-5 As shown, when splicing tiles, the first overlap of any tile is placed on the second overlap of the adjacent tile, and the strip-shaped sealing block is engaged with the groove. The first and second waterproof grooves form completely independent spaces due to the engagement of the sealing strip and the limiting strip. Even if rainwater seeps in at the joint between the tile body and the first overlap of the two adjacent tiles, it will flow into the first waterproof groove and be discharged from the first waterproof groove. If the sealing strip and the limiting strip become loose due to long-term use or impact from heavy objects, water will seep from the first waterproof groove into the second waterproof groove and be discharged from the second waterproof groove. The sealing block and the groove still remain tightly engaged, effectively preventing rainwater from leaking into the building interior, resulting in good waterproofing performance.
