Description

Technical Field

[0001] This invention relates to the field of solar building materials technology, specifically to a fixing device for tile installation and a detachable fish-scale tile having the same. Background Technology

[0002] With the continuous development of new energy sources and the increasing demand for urban energy conservation, emission reduction, and green environmental protection, solar photovoltaic products are becoming increasingly popular. Solar photovoltaic tiles replace traditional roofing tiles, not only without affecting the aesthetics of the building facade but also integrating well with the building structure, increasing the functionality of the roof tiles by converting absorbed solar energy into electrical energy. This significantly reduces the overall outdoor temperature, decreases roof heat and indoor air conditioning cooling load, thus contributing to building energy conservation. Solar photovoltaic tiles have become the optimal installation method for the widespread application of photovoltaic power generation systems in cities.

[0003] However, most traditional roof tiles on the market are fixed with steel nails, and some photovoltaic products are fixed with structural adhesive. The nails are exposed, which not only affects the overall appearance, but also makes it inconvenient to disassemble and replace the tiles in a timely manner. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art in that the tiles are not easy to disassemble and replace, thereby providing a fixing device for tile installation that facilitates the disassembly and replacement of tiles, and a detachable fish scale tile having the same.

[0005] To address the aforementioned technical problems, the present invention provides a fixing device for tile installation, comprising:

[0006] The fastener has a first end that passes through and is fixed to the tile and a second end that extends radially to protrude from the body portion of the fastener;

[0007] A rotating component having an opening that allows the main body and second end of the fastener to pass through radially;

[0008] The mounting component has a mounting portion fixed to the support frame and a groove that allows the rotating component to pass through axially and the fastener to pass through radially; after the fastener reaches a predetermined position of the rotating component, it rotates together with the rotating component to a radial inlet that deviates from the groove, and then forms a fastening structure with the mounting component.

[0009] Furthermore, the groove includes a first groove adapted to the rotating component and a second groove adapted to the main body and second end of the fastener.

[0010] Furthermore, the opening of the rotating component is consistent with the shape of the second groove.

[0011] Furthermore, the axial cross-section of the opening and the second groove on the rotating component is both convex.

[0012] Furthermore, a spring sheet is provided on the contact surface between the fastener and the rotating component.

[0013] Furthermore, the mounting portion of the mounting component is inverted U-shape, including a first plate, a second plate, and a third plate connected in sequence. The first plate has a through hole for connecting the support frame. The groove is formed on the second plate and at the connection between the second plate and the third plate. The third plate has a bent portion that bends toward the first plate.

[0014] The present invention also provides a detachable fish-scale tile, including the aforementioned fixing device, and further including a support frame for mounting the fixing device, wherein the tile is fixed between a fastener and a rotating component.

[0015] Furthermore, the tiles in adjacent rows are interlocked on the support frame in a stepped arrangement.

[0016] Furthermore, it also includes connectors installed on both sides of the bottom of the tile and fixedly connected to the support frame.

[0017] Furthermore, the connector has a first water guide groove and a second water guide groove, which are arranged to overlap each other.

[0018] The technical solution of this invention has the following advantages:

[0019] 1. The fixing device for tile installation provided by the present invention has a rotating component that enters into the mounting component axially, and a fastener that enters radially into the opening on the rotating component in the mounting component. The rotating component and the fastener are rotated together by a certain angle until the opening on the rotating component is rotated to a position away from the groove on the mounting component, thereby fixing the tile to the mounting component. The rotating component and the fastener are fitted together on the mounting component, and after rotation, the second end of the rotating component, the fastener, and the groove are not on the same axis. The second end of the fastener is axially fixed to the inner surface of the mounting component, preventing the tile from loosening due to the fastener falling off, thus affecting the overall stability of the tile. Moreover, during disassembly and replacement, it is only necessary to rotate the rotating component and the fastener in opposite directions by a corresponding angle to the opening of the groove on the mounting component, and then slide the fastener out of the groove. Disassembly and replacement can be easily completed without the need for other tools, improving work efficiency. In existing technologies, tiles are fixed with steel nails, which require tools to remove, making tile disassembly inconvenient. Some products also use structural fixing adhesive or expose the fixing nails, affecting the overall aesthetics of the tiles. This invention not only facilitates disassembly but also satisfies the overall aesthetic requirements, achieving a perfect integration with the building and reflecting the applicability and artistry of the architecture.

[0020] 2. The fixing device for tile installation provided by the present invention has an axial cross-section of both the opening and the second groove on the rotating component being U-shaped. This facilitates the fastener entering the rotating component through the second groove for rotation. This design effectively limits the axial displacement of the second end of the fastener along the mounting component, preventing the second end of the fastener from moving axially along the mounting component, which could cause the tile to loosen and affect the overall stability of the tile.

[0021] 4. The fixing device for tile installation provided by the present invention further includes a spring plate on the contact surface between the fastener and the rotating component. The purpose of adding the spring plate is to prevent the fastener and the rotating component from loosening after installation, thereby preventing the tile from falling off.

[0022] 5. The fixing device for tile installation provided by the present invention comprises an inverted U-shaped mounting portion of a mounting member, including a first plate, a second plate, and a third plate connected in sequence. The first plate has a through hole for connecting the support frame. A groove is formed in the second plate and at the connection between the second and third plates. The third plate has a bent portion that bends towards the first plate. The bent portion supports the mounting member and provides installation space for a rotating component and a fastener between the mounting member and the support frame, allowing the first end of the rotating component and the fastener to rotate within the mounting member after installation, thereby achieving a fastening purpose.

[0023] 6. The detachable fish-scale tile provided by the present invention has adjacent rows of tiles overlapping each other on the support frame in a stepped arrangement. The overlapping arrangement covers the fasteners on the mounting parts used to fix the tiles, eliminating exposed fasteners and making the entire fish-scale tile more aesthetically pleasing. The stepped arrangement of the tiles also facilitates rain and snowfall, allowing them to fall naturally along the tiles and preventing excessive accumulation of snow from damaging the fish-scale tiles.

[0041] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1-4One specific embodiment of the fixing device for tile installation shown includes: a fastener having a first end 1 that passes through and is fixed to the tile 11 and a second end 3 that extends radially to a body portion 2 protruding from the fastener; a rotating member 4 having an opening 5 that allows the body portion 2 and the second end 3 to pass radially through; and a mounting member 6 having a mounting portion fixed to a support frame 10 and a groove 7 that allows the rotating member 4 to pass axially and the fastener to pass radially; after the fastener reaches a predetermined position of the rotating member 4, it rotates together with the rotating member 4 to a radial inlet offset from the groove 7, thereby forming a fastening structure with the mounting member 6.

[0043] The fastener has a hexagonal screw at one end 1 and a cuboid body 2. A second end 3 is formed on the bottom of the body 2. The second end 3 is cylindrical with a diameter larger than the width of the cuboid. The opening 5 on the rotating part 4 is compatible with the cuboid body 2 and the cylindrical second end 3. During installation, EPDM rubber is first fitted into the fixing hole of the tile 11 to be installed. Then, the rotating part 4 passes through the groove 7 axially. Next, the second end 3 of the fastener with the tile 11 installed passes through the groove 7 radially. The rotating part 4 and the fastener are rotated together by 180°. After rotation, the opening 5 of the rotating part 4 is aligned with the opening of the groove 7, thereby fixing the tile 11 to the mounting part 6. The entire structure is relatively simple and the fixing is convenient and reliable. EPDM rubber has excellent weather resistance, heat resistance, acid and alkali resistance, and water vapor resistance, which protects the fastener and allows it to be used in harsh environments, extending its service life.

[0044] The groove 7 includes a first groove 71 adapted to the rotating member 4 and a second groove 72 adapted to the main body 2 and the second end 3 of the fastener. The opening 5 of the rotating member 4 has the same shape as the second groove 72. The axial cross-section of the opening 5 and the second groove 72 on the rotating member 4 is convex.

[0045] The first groove 71 is circular, matching the shape of the rotating component 4, facilitating axial insertion of the rotating component 4. The opening 5 and the axial cross-section of the second groove 72 are convex, allowing the fastener to enter the rotating component 4 through the second groove 72 for rotation. This design effectively limits the axial displacement of the second end 3 of the fastener along the mounting component 6, preventing the second end 3 of the fastener from moving along the axial direction of the mounting component 6, thus preventing the tile 11 from loosening and affecting the overall stability of the tile 11. A spring sheet is also provided on the contact surface between the fastener and the rotating component 4. The purpose of adding the spring sheet is to prevent loosening of the fastener and rotating component 4 after installation, which could lead to the tile 11 falling off.

[0046] The mounting part of the mounting component 6 is inverted U-shaped and includes a first plate 61, a second plate 62 and a third plate 63 connected in sequence. The first plate 61 has a through hole 8 for connecting the support frame 10. The groove 7 is formed at the second plate 62 and at the connection between the second plate 62 and the third plate 63. The third plate 63 has a bent part 64 that bends toward the first plate 61. The mounting part 6 has three sides in contact with the support frame 10 and is clamped on both sides of the support frame 10, which increases the contact area between the mounting part 6 and the support frame 10 and makes the fixation more reliable. The screw passes through the through hole 8 to fix the mounting part 6 to the support frame 10. The first groove 71 of the groove body 7 is formed on the second plate 62 of the mounting part, and the second groove 72 is formed at the connection between the second plate 62 and the third plate 63. The bent part 64 of the third plate 63 has a convex opening. The bent part 64 plays the role of supporting the mounting part 6. Between the mounting part 6 and the support frame 10, there is an installation space for the rotating part 4 and the fastener, so that the first end 1 of the rotating part 4 and the fastener can rotate in the mounting part 6 after installation, thereby achieving the purpose of fastening.

[0047] As an alternative implementation, the second end 3 of the fastener can also be a boss or other polygonal structure, and the opening 5 on the rotating part 4 can be adapted to the structure of the second end 3 of the fastener, as long as it can be ensured that the rotating part 4 and the fastener will not detach from the groove 7 of the mounting part 6 along the axial direction after rotation.

[0048] like Figure 5-9 One specific embodiment of the detachable fish-scale tile shown includes the aforementioned fixing device and a support frame 10 for mounting the fixing device. The tile 11 is fixed between the fastener and the rotating component 4. Adjacent rows of the tile 11 are cross-overlaid on the support frame 10 in a stepped arrangement.

[0049] The support frame 10 is formed by several mutually perpendicular keels fixed together and divided into multiple rectangular installation spaces. Adjacent rows of tiles 11 overlap on the support frame 10, forming a stepped arrangement. At the starting end of the support frame 10, there is a starting tile 12, which is made of polymer material and has a size of 200×800mm. That is, one end of the first row of tiles 11 is fixed to the support frame 10 by the mounting piece 6, and the other end of the tile 11 overlaps on the starting tile 12. The second row of tiles 11 overlaps with the first row of tiles 11 and covers the fasteners on the first row of tiles 11, making the overall appearance of the installed tiles 11 more aesthetically pleasing. The overlapping of the tiles 11 in a stepped form allows rain and snow to fall naturally along the tiles, preventing the fish-scale tiles from being damaged by excessive accumulation of snow.

[0050] like Figure 6As shown, the tiles are cut according to the commonly used dimensions of traditional tiles on the market: the size of a traditional tile is 270×410mm, and the length-to-width ratio is calculated to be 1:1.52. Solar module chips are used, and the size of the solar module chips is 1190×790mm. Based on the length-to-width ratio and the size of the solar module chips, 12 tiles can be cut, and the size of each tile is 290×250mm, minimizing the waste during cutting.

[0051] like Figure 7 As shown, the fish-scale tile, from top to bottom, comprises a front panel glass 111, an adhesive film 112, a photovoltaic chip 113, butyl rubber 114, an adhesive film 112, and a back panel glass 115. The back panel glass 115 has dimensions of 490×400mm. The photovoltaic chip 113 is located in the middle of the back panel glass 115, with a distance of 50mm between the left end and the back panel glass 115 and 60mm between the right end. The photovoltaic chip 113 is located near the arc of the tile 11. The fastener is located at the end of the tile 11 away from the arc, 50mm from the edge. This arrangement avoids the possibility of gaps appearing between the fastener and the edge of the tile 11 due to the fastener being too close to the edge, thus achieving a better fastening purpose.

[0052] The wires and junction box are connected to the bottom of tile 11. The detachable design facilitates inspection and replacement in case of problems.

[0053] like Figure 8-9 As shown, it also includes connectors 9 installed on both sides of the bottom of the tile 11 and fixedly connected to the support frame 10. The connectors 9 have a first water guiding channel 91 and a second water guiding channel 92, which are arranged to overlap each other. A first water guiding channel 91 is provided at one end of the bottom of the tile 11 along the length direction, and a second water guiding channel 92 is provided at the other end. The first water guiding channel 91 and the second water guiding channel 92 at the bottom of two adjacent tiles 11 overlap to form a general U-shape, which facilitates the storage of rainwater.

[0054] The specific installation method of fish scale tiles: First, install the starting tile 12 on the support frame 10, then install the mounting piece 6 on the support frame 10. Adjacent tiles 11 should overlap left and right. Considering the current installation error, leave a 5mm width for on-site adjustment tolerance. Install the connecting piece 9 at the bottom of the tile 11. Each tile 11 has two fasteners. Then, the rotating piece 4 passes axially through the groove 7. Next, the second end 3 of the fastener with the tile 11 installed passes radially through the groove 7. Rotate the rotating piece 4 and the fastener together 180°. After rotation, the opening 5 of the rotating piece 4 and the groove 7... With the openings facing each other, the tile 11 is fixed to the mounting piece 6, and the other end overlaps the starting tile 12. The joints of the first row of tiles 11 and the starting tile 12 should be staggered by 200mm. Install them in sequence until the installation of the first row of tiles 11 is completed. When installing the second row of tiles 11, install the second row of tiles 11 alternately on the first row of tiles 11, and then fix the tile 11 to the mounting piece 6 with fasteners. The other end overlaps the first row of tiles 11 with an overlap length of 165mm, thereby covering the fasteners on the first row of tiles 11. Continue in this way until the installation of the entire fish scale tile is completed.

[0055] The specific disassembly method of fish scale tile: First, lift the first tile 11 located on the upper layer by 10mm. Use a wrench to rotate the fastener of the second tile 14 located on the lower layer counterclockwise by 180°. Then lift the second tile 14 by 5mm and separate the fastener from the mounting part 6. Mark the installation position of the second tile 11 along the support frame 10 to complete the disassembly.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
