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 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 tile having the same.

[0005] To solve the above-mentioned 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] The mounting component has a mounting portion fixed to a support frame and a groove that allows a second end of the fastener to pass through axially, wherein the second end of the fastener forms a fastening structure with the mounting component after passing through the groove and rotating to a position offset from the groove.

[0008] Furthermore, the groove includes a first groove adapted to the main body of the fastener and a second groove adapted to the second end of the fastener.

[0009] Furthermore, both the second end of the fastener and the second groove are fan-shaped.

[0010] Furthermore, the first end and the main body of the fastener are connected by threads.

[0011] Furthermore, a spring sheet is also provided on the contact surface between the first end and the main body.

[0012] Furthermore, the mounting portion of the mounting component is inverted U-shaped and includes a first plate, a second plate, and a third plate connected in sequence. The first plate has a first through hole for connecting the support frame, the groove is formed on the second plate, and the third plate has a bent portion that bends toward the first plate.

[0013] A removable tile is also provided, including the aforementioned fixing device, and further including a support frame for mounting the fixing device, wherein the tile is fixed between the fastener and the mounting member.

[0014] Furthermore, adjacent rows of tiles overlap on the support frame to form a stepped arrangement.

[0015] Furthermore, it also includes a connector disposed between two adjacent rows of the tiles, at least one end of the connector being fixed to the support frame.

[0016] Furthermore, the connector has a water guide groove arranged along the inclined direction of the tile and a flow-limiting protrusion formed at the outlet of the water guide groove.

[0017] The technical solution of this invention has the following advantages:

[0018] 1. The fixing device for tile installation provided by the present invention has a second end of a fastener that enters the mounting component axially. The fastener is rotated at a certain angle until the second end is rotated to a position offset from the groove on the mounting component, thereby fixing the tile to the mounting component. The shape of the second end of the fastener is adapted to the shape of a portion of the groove on the mounting component, facilitating the smooth passage of the second end of the fastener through the groove. Furthermore, the second end of the fastener after rotation is not on the same axis as the groove, and the second end of the fastener is axially fixed to the inner surface of the mounting component, preventing the tile from loosening due to fastener detachment, thus affecting the overall stability of the tile. Moreover, disassembly and replacement only require rotating the second end of the fastener 180° in the opposite direction, eliminating the need for other tools and improving work efficiency. This fixing device can not only fix flat tiles, but also meet the requirements for fixing curved tiles. In the prior art, tiles are fixed with steel nails, which require tools to remove, making it inconvenient to disassemble the tiles. Some products also use structural adhesive or expose the fixing nails, affecting the overall aesthetics of the tiles. This invention not only facilitates disassembly, but also meets the overall aesthetic requirements, achieving a perfect integration with the building and reflecting the applicability and artistry of the architecture.

[0019] 2. The fixing device for tile installation provided by the present invention includes a groove comprising a first groove adapted to the main body of the fastener and a second groove adapted to the second end of the fastener. Due to the irregular arrangement of the second end of the fastener, the groove needs to both match it to ensure smooth installation of the fastener and be fixed to the mounting component after the second end is rotated at a certain angle.

[0020] 3. The fixing device for tile installation provided by the present invention has a fastener whose first end and main body are connected by a thread. The threaded connection has advantages such as simple structure, reliable connection, and convenient disassembly. When installing or removing tiles, the first end of the fastener is removed first, making it easier to observe whether the second end of the fastener corresponds to the groove on the mounting piece. This avoids the first end of the fastener obstructing the view of the second end, reducing the time required for the entire process and improving the efficiency of installation or disassembly.

[0021] 4. The fixing device for tile installation provided by the present invention further includes a spring sheet on the contact surface between the first end and the main body. The function of adding the spring sheet is to provide an elastic buffer distance between the first end of the fastener and the tile, thereby reducing the direct force acting on the tile due to stress concentration caused by excessive force during installation, which could lead to tile deformation or damage.

[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 first through hole formed for connecting the support frame. The groove is formed on the second plate. The third plate has a bent portion bent towards the first plate. The bent portion supports the mounting member, and a space is provided between the mounting member and the support frame for fasteners.

[0023] 6. The detachable tiles provided by this invention have adjacent rows of tiles overlapping on the support frame to form 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 tile more aesthetically pleasing. The stepped arrangement also facilitates rain and snowfall, allowing them to fall naturally along the tiles and preventing damage from excessive snow accumulation. Attached Figure Description

[0035] 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.

[0036] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1-3One 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 14 and a second end 4 that extends radially to a body portion 3 protruding from the fastener; and a mounting member 6 having a mounting portion fixed to a support frame 12 and a groove 5 that allows the second end 4 of the fastener to pass through axially, the second end 4 of the fastener forming a fastening structure with the mounting member 6 after passing through the groove 5 and rotating to a position offset from the groove 5.

[0038] The fastener has a hexagonal screw at its first end 1 and a cylindrical body 3. A second end 4 is formed radially on the body 3. The groove 5 is closed, meaning it does not extend to the edge of the mounting piece 6. During installation, EPDM rubber is first inserted into the fixing hole of the tile to be installed. Then, the second end 4 of the fastener is passed axially through the groove 5, and the fastener is rotated 180°. After rotation, the second end 4 of the fastener is aligned with the opening of the groove 5, thereby fixing the tile 14 to the mounting piece 6. The entire structure is relatively simple in design 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.

[0039] Based on the commonly used dimensions of traditional roof tiles on the market: the traditional tile size is 270×410mm, and the calculated length-to-width ratio is 1:1.52. Using solar module chips, 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, it is calculated that 9 tiles can be cut, each tile 14 with a size of 260×395mm, minimizing the loss during cutting. Two circular holes with a diameter of 12mm are made on each tile 14 to facilitate the passage of the second end 4 of the fastener and to fix the tile to the mounting piece 6.

[0040] The groove 5 includes a first groove 51 adapted to the main body 3 of the fastener and a second groove 52 adapted to the second end 4 of the fastener. Both the second end 4 and the second groove 52 are fan-shaped. The first groove 51 is a circular groove formed to fit the main body 3, and the second groove 52 is a groove formed to fit the second end 4. Designing the second end 4 as a fan shape increases the contact area between the second end 4 and the mounting part 6, making the fixation more stable and reliable.

[0041] In one specific embodiment, the first end 1 and the main body 3 of the fastener are connected by a thread. The threaded connection is a detachable connection, although other connection methods are also possible. Threaded connections have advantages such as simple structure, reliable connection, and convenient disassembly. When installing or removing the tiles, the first end 1 of the fastener is removed first, making it easier to observe whether the second end 4 of the fastener corresponds to the groove 5 on the mounting piece. This avoids the first end 1 of the fastener obstructing the installation view of the second end 4, reducing the time required for the entire process and improving the efficiency of installation or disassembly.

[0042] The mounting portion of the mounting component 6 is an inverted U-shape, comprising a first plate 61, a second plate 62, and a third plate 63 connected in sequence. The first plate 61 has a first through hole 7 for connecting the support frame 12. The groove 5 is formed on the second plate 62. The third plate 63 has a bent portion 64 that bends towards the first plate 61. Three sides of the mounting component 6 contact the support frame 12, clamping it on both sides of the support frame 12, increasing the contact surface between the mounting component 6 and the support frame 12, making the fixation more secure. Screws pass through the first through hole 7 to fix the mounting component 6 to the support frame 12. The bent portion 64 serves to support the mounting component 6. Between the mounting component 6 and the support frame 12, there is an installation space for the fastener, allowing the first end 1 of the fastener to rotate within the mounting component 6 after installation, thereby achieving the purpose of fastening.

[0043] As an alternative implementation, the second end 4 of the fastener can also be a boss or other polygonal structure, and the second groove 52 can be adapted to the structure of the second end 4 of the fastener and the main body 3, as long as it can be ensured that the fastener will not detach from the groove 5 of the mounting part 6 along the axial direction after rotation.

[0044] like Figure 4-5 One specific embodiment of the detachable roof tile shown includes the aforementioned fixing device and a support frame 12 for mounting the fixing device. The tile 14 is fixed between the fastener and the mounting member 6. The support frame 12 is formed by several mutually perpendicularly arranged joists and is divided into multiple rectangular installation spaces. Adjacent rows of tiles 14 overlap on the support frame 12, forming a stepped arrangement. Specifically, the first tile 14 is fixed to the support frame 12 by the mounting member 6, and the second tile 14 has one end fixed to the support frame 12 and the other end overlapping the first tile 14, thus covering the fastener. This makes the installed tiles 14 more aesthetically pleasing, and the stepped arrangement of the tiles allows rain and snow to fall naturally along the tiles, preventing damage from excessive snow accumulation.

[0045] The wires and junction box are connected to the bottom of tile 14. The detachable design facilitates inspection and replacement in case of problems.

[0046] like Figure 6 As shown, it also includes a connector 8 disposed between two adjacent rows of tiles 14, at least one end of the connector 8 being fixed to the support frame 12. The connector 8 has a water guide groove 10 disposed along the inclined direction of the tile 14 and a flow-limiting protrusion 11 formed at the outlet of the water guide groove 10. A baffle 13 is provided at one end of the water guide groove 10 to prevent water from flowing out, and a flow-limiting protrusion 11 is provided at the other end. The two connectors 8 are connected end to end, that is, the baffle 13 and the flow-limiting protrusion 11 are adjacent to each other and used in conjunction to prevent a large amount of rainwater from flowing into the next connector 8. A connecting part for connecting to the support frame 12 is provided below the connector 8 near the baffle 13. A second through hole 9 is provided on the connecting part. The connector 8 is installed on the support frame 12 by screws, and the other end overlaps the support frame 12, thus supporting the tile 14 to complete the laying.

[0047] The specific installation method of the tiles is as follows: First, install the mounting piece 6 on the support frame 12. Then, install the connector 8 according to the size of the tile 14, with adjacent tiles 14 overlapping each other. Considering the installation error of the current operation, leave a 5mm width for adjustment tolerance. Then, fix the tile 14 to the mounting piece 6 and connector 8 with fasteners. Each tile 14 has two fasteners, with the other end overlapping the support frame 12, until the installation of the first row of tiles 14 is completed. Then, install the second row of tiles 14. Install the mounting piece 6 on the support frame 12. Align the flow-limiting protrusion 11 of the second row of connector 8 with the baffle on the first row of connector 8. Then, fix the tile 14 to the mounting piece 6 and connector 8 with fasteners, with the other end overlapping the first row of tiles 14 with an overlap length of 50mm, thus covering the fasteners of the first row of tiles 14. Continue in this way until the installation of the entire tile is completed.

[0048] The specific disassembly method of the tile is as follows: First, lift the first tile 14 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 piece 6. The second tile 14 is then marked with the mounting position along the direction of the connector 8, thus completing the disassembly.

[0049] 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.
