Description

Technical Field

[0001] This application relates to the field of structures for installing solar photovoltaic tiles on the roofs of civil buildings, and in particular to a small tile structure. Background Technology

[0002] On the roofs of traditional buildings, multiple rows of tiles are spliced ​​together to form a wave-like shape to achieve the antique aesthetic style required by traditional buildings. At the same time, based on the requirements of building energy conservation and the need for zero-energy buildings, laying a photovoltaic power generation layer on the tiles can provide clean and green energy for the building through photovoltaic power generation. When designing the tile structure, wind resistance factors need to be considered to ensure the stability of the tiles installed on the roof.

[0003] In related technologies, to improve the wind resistance of roof tiles and ensure their stability, Chinese Patent Publication No. CN209429400U discloses a roof tile installation device, a roof tile assembly, and a power generation system. The roof tile installation device includes: an installation sleeve fitted into the roof tile installation hole, the installation sleeve having an installation through hole and a positioning through hole; and a hook portion that can slide from the positioning through hole to the fixed installation through hole for detachably fixing the roof tile to a roof tile hanger. When using the above-mentioned roof tile installation device, the installation sleeve is placed inside the roof tile installation hole to protect the roof tile, and the hook portion is fixed to the roof tile hanger. Then, the roof tile with the installation sleeve installed can be held and the roof tile is inserted through the positioning through hole into the hook portion. Moving the roof tile causes the hook portion to move from the positioning through hole to the installation through hole, thus locking the roof tile in its installation position.

[0004] Regarding the aforementioned technologies, when installing tiles, each tile needs to be connected to a hook and a tile hanger, requiring personnel to use multiple hooks to secure each tile individually, which is inconvenient for workers. Summary of the Invention

[0005] To facilitate the fixing of adjacent tiles, this application provides a small tile structure.

[0006] The small tile structure provided in this application adopts the following technical solution:

[0007] A small tile structure, comprising:

[0008] The tile body includes a ridge, a first outward flange, and a second outward flange. The ridge is fixedly connected between the first outward flange and the second outward flange. The ridge is protruding, and the protruding direction is consistent with the orientation of the opening of the first or second outward flange.

[0009] And, a first pressure strip, the first pressure strip is fixedly connected to the tile body, and the first pressure strip and the first outer flange are located on the same side of the tile ridge. A first insertion area is formed between the first pressure strip and the first outer flange. The opening of the first insertion area faces the side of the tile ridge away from the second outer flange, and the first insertion area is used for the insertion of the second outer flange on another tile body.

[0010] By adopting the above technical solution, during operation, the first tile is first laid and fixed on the roof. Next, the installation of the next tile is carried out. During installation, the second outward flange of the next tile is first inserted into the first interlocking area, and then the first outward flange of the next tile is lowered onto the roof to achieve splicing of two adjacent tiles. Therefore, when two adjacent tiles are spliced, the first pressure strip on one tile can press down the second outward flange on the other tile, which can reduce the occurrence of tiles completely separating from the roof in windy conditions. In addition, this solution only requires personnel to insert the second outward flange into the first interlocking area, without requiring personnel to install each tile through multiple other structures, which facilitates the installation work.

[0011] Optionally, a second pressure strip and a limiting strip may also be included;

[0012] The second pressure strip is fixedly connected to the tile body. The second pressure strip and the second outer flange are located on the same side of the tile ridge, and a second insertion area is formed between the second pressure strip and the second outer flange. The opening of the second insertion area faces the side of the tile ridge away from the first outer flange.

[0013] The limiting strip includes a main body and a plug-in part. The main body is fixedly connected between the two plug-in parts. The first plug-in area is for one of the plug-in parts to be inserted, and the second plug-in area is for the other plug-in part to be inserted.

[0014] By adopting the above technical solution, in order to further improve the firmness of the connection between two adjacent tiles, a limiting strip is set between the two adjacent tiles; after splicing the two tiles, one of the insertion parts of the limiting strip is inserted into the first insertion area on one tile, and the other insertion part of the limiting strip is inserted into the second insertion area on the other tile. Thus, the limiting strip can limit the two spliced ​​tiles, which can further improve the firmness of the connection between the two tiles.

[0015] Optionally, when both the insertion part and the second outer flange are inserted into the first insertion area, the first pressure strip is in a deformed state and has a tendency to recover its deformation towards the first outer flange side.

[0016] By adopting the above technical solution, after the second outer flange and the plug-in part are both inserted into the first plug-in area, since the first pressure strip is in a deformed state, the first pressure strip has a tendency to recover its deformation, which allows the first pressure strip to press the second outer flange and the plug-in part towards the first outer flange. This has the following beneficial effects: First, since the plug-in part is pressed by the first pressure strip, the connection between the plug-in part and the two tile bodies is more secure. Second, since the first pressure strip can press the plug-in part, there is at least a line contact between the first pressure strip and the plug-in part, which can play a certain sealing role in the connection between the first pressure strip and the plug-in part, and can reduce the occurrence of water leakage at the connection between the first pressure strip and the second plug-in part.

[0017] Optionally, when the plug is inserted into the second plug area, the second pressure strip is in a deformed state and has a tendency to recover its deformation towards the first outward flange side.

[0018] By adopting the above technical solution, after the plug-in part is inserted into the second plug-in area, since the second pressure strip is in a deformed state, the second pressure strip can press the plug-in part against the second outer flange, so that one side of the limiting strip is pressed by the first pressure strip and the other side is pressed by the second outer flange. Therefore, the limiting strip can connect the two tile bodies more firmly.

[0019] Optionally, the longitudinal section of the main body is convex toward the side away from the first outward flange and / or the second outward flange, and the opening formed therein faces toward the first outward flange and / or the second outward flange.

[0020] Furthermore, the main body can undergo recoverable elastic deformation under external force, causing the main body to tend to expand toward the insertion portions on both sides.

[0021] By adopting the above technical solution, if it is necessary to install the interlocking parts between two tiles, a person presses the main body to deform it, causing the two interlocking parts to move towards each other. After the distance between the two interlocking parts decreases, the person can move the limiting strip so that the limiting strip passes through the gap between the first and second pressure strips. Subsequently, the person releases the force applied to the main body, and as the main body recovers its deformation, it will drive the two interlocking parts to move, allowing the interlocking parts to be inserted into the first and second interlocking areas. This connection method... Compared to related technologies where each tile and its hanging strip are connected indirectly through other structures, this method directly connects two adjacent tiles through a single structure. After the adjacent tiles are connected by limiting strips, the connecting strips are mutually limiting each other between the tiles. Furthermore, the adjacent tiles are also pressed against each other by the first and second outward flanges. Therefore, after multiple limiting strips connect multiple tiles, the tiles and limiting strips press against each other, and the combined force formed can withstand greater wind force, thus making the connection between adjacent tiles more secure.

[0022] Optionally, a photovoltaic power generation layer is laid along the surface of the ridge portion on the side away from the opening of the protrusion.

[0023] By adopting the above technical solution, the ridge of the tile is designed to be raised, and the power generation layer laid on the surface of the ridge is consistent with the raised surface of the ridge. Therefore, within a unit projected area, the raised structure can have a larger unfolded area, thereby enabling the power generation layer to receive more sunlight and increasing the power generation within a unit projected area.

[0024] Optionally, the surface of the main body is provided with a reflective layer, which is located on the raised side surface of the main body.

[0025] By adopting the above technical solution, since the main body is located between two tiles and the tiles are convex, when sunlight shines at an angle, the sunlight shining on the main body can be reflected by the reflective layer to the back surface of the tile ridge, thereby increasing the power generation of the power generation layer to a certain extent.

[0026] Optionally, the end of the first pressure strip away from the ridge of the tile is configured as a curved edge facing away from the first outward flange;

[0027] The end of the second pressure strip away from the ridge of the tile is configured as a curved edge facing away from the second outward flange.

[0028] By adopting the above technical solution, by setting the sides of the first and second outward flanges as curved edges, the size of the opening ends of the first and second insertion areas can be increased. Thus, the larger opening makes it easier for personnel to insert the second outward flange and the insertion part more smoothly, which facilitates the construction work.

[0029] Optionally, a flexible pad is provided between the plug-in portion and the first pressure strip, and the flexible pad is also provided between the plug-in portion and the second pressure strip.

[0030] By adopting the above technical solution, since the first and second pressure strips are both in a deformed state when the plug is inserted into the first and second plug areas, the first and second pressure strips have a pressing effect on the flexible pad. Therefore, the pressed flexible pad is in surface contact with the first and second pressure strips and the plug. Thus, the sealing between the plug and the first and second pressure strips can be further improved by the flexible pad, thereby reducing the occurrence of water seepage from the connection between the plug and the first and second pressure strips.

[0031] Optionally, a limiting member is also included. The limiting member is fixedly connected to the main body. When the two insertion parts are respectively inserted into the first insertion area and the second insertion area, the limiting member is inserted into the second outer flange.

[0032] By adopting the above technical solution, during the insertion of the limiting strip, the personnel squeeze the main body and then remove the external force applied to the main body after inserting the connector into the second outer flange. The connector can then be inserted into the first and second insertion areas more accurately according to the preset position. By setting the connector, it is convenient for personnel to install the limiting strip quickly and accurately.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. This application, by setting a first outward flange, a second outward flange, and a first pressure strip, enables two adjacent tiles to be connected through the first outward flange, the second outward flange, and the first pressure strip. When the wind blows, the presence of the first pressure strip can prevent the two tiles from separating. Furthermore, in the process of connecting two adjacent tiles, it is only necessary to insert the second outward flange on one tile into the first insertion area on the other tile, which not only provides wind resistance but also facilitates installation work.

[0035] 2. By setting a second pressure strip and a limiting strip, the limiting strip can further fix two adjacent tiles. At the same time, since the limiting strip not only exists as a structure to fix the tiles, it can also seal the connection between two adjacent tiles.

[0036] 3. By setting a reflective layer on the main body, the contact between the power generation layer on the ridge of the tile and the light can be improved to be more sufficient;

[0037] 4. The plug-in connectors make it easy for personnel to quickly and accurately install the limit strip. Attached Figure Description

[0052] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0053] This application discloses a small tile structure. (Refer to...) Figure 1 The small tile structure includes a tile body 1, which includes a ridge 11, a first outward flange 12, and a second outward flange 13. When the tile body 1 is laid on the roof, it is a horizontally placed strip, and the ridge 11 has a downward opening, i.e., the ridge 11 is convex. The ridge 11 is connected to the first outward flange 12 on one side of its long side and to the second outward flange 13 on the other side. Both the first outward flange 12 and the second outward flange 13 are turned upward to form an upward-facing receiving area. It should be noted that the first outward flange 12 and the second outward flange 13 can be integrally connected to the ridge 11 or welded together. In this embodiment, integral connection is preferred.

[0054] Reference Figure 2 In order to realize photovoltaic power generation, the ridge portion 11 itself can be a power generation layer, or a photovoltaic power generation layer 14 can be connected to the upper surface of the ridge portion 11, so that the ridge portion 11 serves as a carrier supporting the photovoltaic power generation layer 14. In this embodiment, the ridge portion 11 is preferably used as a carrier of the photovoltaic power generation layer 14.

[0055] Reference Figure 1 and Figure 2 Each tile body 1 includes at least one ridge 11. When there is one ridge 11, the single ridge 11 is connected between the first outer flange 12 and the second outer flange 13. When there are multiple ridges 11, the multiple ridges 11 are arranged sequentially in the horizontal direction along the direction perpendicular to the long side of the ridge 11. Adjacent ridges 11 are integrally connected or spliced ​​together, and the adjacent ridges 11 are smoothly connected. The longitudinal section at the connection of adjacent ridges 11 is an arc shape with an upward opening. The first outer flange 12 and the second outer flange 13 are connected to the side of the two ridges 11 located at the edge that are far away from each other.

[0056] Reference Figure 2 and Figure 3The downward opening formed by the ridge portion 11 is primarily intended to increase the light-receiving area on the upper surface of the ridge portion 11 per unit projected area. Therefore, the shape of the longitudinal section of the ridge portion 11 includes, but is not limited to, the following ridge shape schemes:

[0057] Roof ridge shape scheme 1: Refer to Figure 1 and Figure 2 The top of the ridge 11 is flat. The two sides of the ridge 11 are bent downwards and integrally connected with the first outer flange 12 or the second outer flange 13. Here, in order to increase the area of ​​the overall upper surface of the ridge 11 under the projected area, one side of the ridge 11 is inclined downwards towards the first outer flange 12, and the other side is inclined downwards towards the second outer flange 13, rather than making the side of the ridge 11 vertical. In order to facilitate the later installation of the photovoltaic power generation layer 14, the bend of the ridge 11 needs to be in an arc-shaped smooth transition to prevent the photovoltaic power generation layer 14 from being unable to be installed or from breaking due to excessive bending when it is attached to the surface of the ridge 11. It should be noted that if the photovoltaic power generation layer 14 is an ultra-thin flexible crystalline silicon cell as the basic material, it can be directly molded into an arc-shaped smooth transition by molding.

[0058] Meanwhile, the new ultra-thin flexible crystalline silicon battery is only 90-110 micrometers thick, which can be applied to the molding surface under certain curved conditions. The cost of flexible thin film batteries is rapidly decreasing, providing cost and technical advantages for the production and manufacturing of curved power generation tiles. A small tile structure conforms to the aesthetic habits of traditional Chinese and even Asian architecture, allowing traditional building roof tiles to generate electricity without changing the architectural style, and improving the quality of the building.

[0059] Roof ridge shape scheme 2: Refer to Figure 3 The ridge portion 11 is an arc shape with an opening facing downwards. It should be clarified that the arc shape limited by this shape scheme 2 does not only include circular arcs, but other arc shapes are also included in the scope of this application.

[0060] Reference Figure 4 When two tile bodies 1 are overlapped, the second outer flange 13 of one tile body 1 is overlapped on the first outer flange 12 of the other tile body 1, thus achieving the overlap between the two tile bodies 1. Here, in order to ensure that the bottom of the first outer flange 12 is in line contact with the bottom end of the upper surface of the first outer flange 12 when the two adjacent tile bodies 1 are overlapped, so as to prevent water from flowing from the overlap of the second outer flange 13 and the first outer flange 12 to the roof, and in order to ensure that the highest point of the ridge 11 of the multiple tile bodies 1 is on the same surface when the two adjacent tile bodies 1 are overlapped, the designer makes the bottom of the second outer flange 13 more raised than the bottom of the first outer flange 12, which is also within the scope of protection of this application.

[0061] Reference Figure 5 and Figure 6 To reduce the separation of the second outer flange 13 from the first outer flange 12 during the overlapping state, a first pressure strip 2 is provided on the tile body 1. The first pressure strip 2 and the first outer flange 12 are located on the same side of the tile ridge 11. The long side of the first pressure strip 2 is parallel to the long side of the tile ridge 11. A first insertion area 21 is formed between the first pressure strip 2 and the first outer flange 12. The first insertion area 21 is used for the insertion of the second outer flange 13 on other tile bodies 1. In order to maximize the light-receiving area on the upper surface of the tile ridge 11, the connection position of the first pressure strip 2 and the tile ridge 11 is lower than the highest position of the tile ridge 11.

[0062] Reference Figure 5 and Figure 6 In order to facilitate the insertion of the second outer flange 13 on other tile bodies 1 into the first insertion area 21, the first pressure strip 2 is bent upward on the side away from the tile ridge 11 connected to it to form a curved edge, so as to increase the size of the opening end of the first insertion area 21, thereby making it easier for personnel to insert the second outer flange 13 into the first insertion area 21 more smoothly.

[0063] Reference Figure 5 and Figure 6 Personnel insert the second outer flange 13 into the first insertion area 21. When the wind blows, the first pressure strip 2 blocks the second outer flange 13, thus preventing the wind from blowing the second outer flange 13 off the first outer flange 12.

[0064] Reference Figure 7 , Figure 8 and Figure 9 To further secure the two overlapping tiles, a second pressure strip 3 is connected to the ridge 11. The second pressure strip 3 and the second outward flange 13 are located on the same side of the ridge 11. The long side of the second pressure strip 3 is parallel to the long side of the ridge 11. A second insertion area 31 is formed between the second pressure strip 3 and the second outward flange 13. The opening of the second insertion area 31 faces away from the ridge 11. In order to maximize the light-receiving area on the upper surface of the ridge 11, the connection position of the second pressure strip 3 to the ridge 11 is lower than the highest position of the ridge 11.

[0065] Reference Figure 9 In order to facilitate the insertion of other structures into the second insertion area 31, the side of the second pressure strip 3 away from the ridge portion 11 connected to it is also bent upward to form a raised edge, so as to increase the size of the opening end of the second insertion area 31, so that personnel can insert other structures into the second insertion area 31.

[0066] Reference Figure 9 and Figure 10The small tile structure also includes a limiting strip 4, which includes a main body 41 and a plug-in part 42. The main body 41 is integrally fixedly connected or welded between the two plug-in parts 42. The long sides of the main body 41 and the plug-in part 42 are parallel to the long side of the tile ridge 11, and the highest point of the main body 41 is higher than the highest point of the plug-in part 42, that is, the main body 41 is convex upward relative to the plug-in parts 42 on both sides. The main body 41 can generate recoverable elastic deformation under the action of external force so that the main body 41 has a tendency to expand towards the plug-in parts 42 on both sides. Materials that can undergo elastic deformation are within the protection scope of this application.

[0067] Reference Figure 9 When the two tile bodies 11 overlap, one of the insertion parts 42 of the limiting strip 4 is inserted into the first insertion area 21, and the other insertion part 42 is inserted into the second insertion area 31.

[0068] The longitudinal cross-sectional shape of the main body 41 includes, but is not limited to, the following main body shape schemes:

[0069] Main shape scheme 1: Reference Figure 9 The cross-section of the main body 41 is an arc shape with an opening facing downwards;

[0070] Main shape scheme 2: Reference Figure 10 The cross-section of the main body 41 is an inverted V-shape with the opening facing downwards;

[0071] It should be clarified that the arc shape in the main shape scheme 1 does not only refer to circular arcs; other shapes with curvature are also within the scope of protection of this application.

[0072] Reference Figure 9 When installing the limiting strip 4, the operator squeezes the main body 41, causing it to deform so that the two plug-in parts 42 move toward the side that is closer to each other, thereby shortening the distance between the two plug-in parts 42 on the side that is farther apart. Then, the limiting strip 4 is moved downward so that the two plug-in parts 42 pass through the position between the first pressure strip 2 and the second pressure strip 3. After that, the operator releases the main body 41, and the two plug-in parts 42 move toward the first plug-in area 21 and the second plug-in area 31 as the main body 41 recovers its deformation. Thus, the limiting strip 4 can be installed in the first plug-in area 21 and the second plug-in area 31.

[0073] Reference Figure 9To ensure the sealing between the two overlapping tile bodies 1 when the plug part 42 is inserted into the first plug area 21 and the second plug area 31; when the second outer flange 13 is inserted into the first plug area 21, a gap is formed between the second outer flange 13 and the first pressure strip 2 for the plug part 42 to be inserted. When both the plug part 42 and the second outer flange 13 are inserted into the first plug area 21, the first pressure strip 2 is in a deformed state, and the first pressure strip 2 has a tendency to move towards the first outer flange 12 to recover its deformed state.

[0074] Reference Figure 9 When the insertion part 42 is inserted into the second insertion area 31, the second pressure strip 3 is in a deformed state, and the second pressure strip 3 has a tendency to recover its deformed state towards the second outward flange 13. Therefore, when the insertion part 42 is inserted into the first insertion area 21 and the second insertion area 31, both the first pressure strip 2 and the second pressure strip 3 exert a squeezing effect on the insertion part 42, thereby ensuring that there is at least line contact between the first pressure strip 2 and the insertion part 42, and between the second pressure strip 3 and the insertion part 42. This prevents water from flowing into the roof from the contact points between the first pressure strip 2 and the insertion part 42, and between the second pressure strip 3 and the insertion part 42. In order to enable the first pressure strip 2 and the second pressure strip 3 to recover their original position after deformation, both the first pressure strip 2 and the second pressure strip 3 are made of materials with elastic deformation. Materials with elastic deformation are all within the protection scope of this application.

[0075] Reference Figure 9 As a preferred embodiment, a flexible pad 5 may also be provided between the first pressure strip 2 and / or the second pressure strip 3 and the insertion part 42. The material selection of the flexible pad 5 includes, but is not limited to, elastic rubber, elastic silicone, etc.; the connection method of the flexible pad 5 includes, but is not limited to, the following connection schemes:

[0076] Connection scheme 1: The first pressure strip 2 and the flexible pad 5 are fixedly connected, and the second pressure strip 3 and the flexible pad 5 are fixedly connected;

[0077] Connection scheme 2: The flexible pad 5 and the plug part 42 are fixedly connected;

[0078] Connection scheme 3: The flexible pad 5 is sandwiched between the first pressure strip 2 and the insertion part 42, and the flexible pad 5 is sandwiched between the second pressure strip 3 and the insertion part 42;

[0079] If connection scheme 1 or connection scheme 2 is used to fix the flexible pad 5 to the carrier, the fixing method includes, but is not limited to, using glue or screws.

[0080] In this embodiment, the connection method of the flexible pad 5 is preferably connection scheme 1, and the flexible pad 5 is fixed to the carrier by adhesive.

[0081] Reference Figure 9The shape of the longitudinal section of the insertion part 42 includes, but is not limited to, the following insertion shape schemes:

[0082] Plug-in shape scheme 1: Refer to Figure 11 The longitudinal cross-sectional shape of the plug part 42 is a horizontally arranged straight line;

[0083] Plug-in shape scheme 2: Refer to Figure 12 The longitudinal cross-sectional shape of the insertion part 42 is an outwardly turned flange that curves upward toward the side away from the main body part 41;

[0084] Insertion shape scheme 3: The longitudinal section of the insertion part 42 is an annular shape with an unclosed port, that is, the insertion part 42 is rolled up into a cylindrical shape;

[0085] Plug-in shape scheme 4: Refer to Figure 9 The longitudinal section of the plug part 42 is an elliptical ring with an unclosed port, that is, the plug part 42 is rolled up into an elliptical cylindrical shape.

[0086] In this embodiment, the shape of the longitudinal section of the insertion part 42 is preferably insertion shape scheme 4, and preferably, the outer diameter of the insertion part 42 in the horizontal direction is larger than the outer diameter in the vertical direction. The elliptical cylindrical shape has shape advantages including, but not limited to, the following:

[0087] Advantage 1 of the shape: Compared with the single-piece structure, the elliptical cylindrical shape allows the upper end to contact the first pressure strip 2 or the second pressure strip 3 to form a line contact, and the lower end to contact the second outer flange 13 or the first outer flange 12 to form a line contact. At the connection of the two tiles 1, both the first pressure strip 2 and the second pressure strip 3 can exert a squeezing effect on the insertion part 42. Therefore, a double waterproof seal is formed at the two sets of line contact points, which can effectively prevent water from flowing into the roof through the overlap of the two tile bodies 1.

[0088] Advantage 2 of shape: Compared with the single-piece structure, the elliptical cylindrical shape requires a higher opening height of the first insertion area 21 and the second insertion area 31. Therefore, when designing the height of the first pressure strip 2 and the second pressure strip 3, the height of the first insertion area 21 and the second insertion area 31 needs to be considered. Thus, when personnel insert the second outer flange 13 and the insertion part 42 into the first insertion area 21 and the insertion part 42 into the second insertion area 31, it can provide a higher space for the first outer flange 12 and the second outer flange 13 to be inserted, which can facilitate the overlapping operation of two tile bodies 1.

[0089] Furthermore, due to the large volume of the tile body 1, when a person holds the first outer flange 12 on one side of the tile body 1 and inserts the second outer flange 13 into the first insertion area 21, the force that the person's hand needs to bear is relatively large under the action of the weight of the tile body 1 and the lever principle. Therefore, when working alone, if the person's hand shakes, a larger amount of shaking will occur on the second outer flange 13 side. At this time, the higher insertion port can facilitate the insertion operation. On the other hand, if the insertion port is small, in order to avoid excessive shaking, multiple people may need to hold the tile. Therefore, the preferred solution of this application can minimize the number of people required for the operation.

[0090] Shape advantage 3: When used in conjunction with the flexible pad 5, the presence of the flexible pad 5 allows the elliptical cylindrical insertion part 42 to be in surface contact with the flexible pad 5. Combined with the squeezing action of the first pressure strip 2 and the second pressure strip 3, it can further ensure the sealing between the two overlapping tile bodies 1.

[0091] Shape advantage 4: Since the outer diameter of the plug part 42 in the horizontal direction is larger than that in the vertical direction, when it is inserted into the first plug area 21 or the second plug area 31, the height of the first plug area 21 and the second plug area 31 at the opening end can be relatively reduced. Therefore, compared to the outer diameter of the plug part 42 in the horizontal direction being smaller than that in the vertical direction, the first pressure strip 2 and the second pressure strip 3 can be installed at a lower position to increase the area of ​​the ridge 11 that can be exposed to sunlight within a unit vertical projection area. In addition, the lower height of the plug part 42 end also makes it easier for personnel to perform plug-in operations on the plug part 42.

[0092] Reference Figure 13 The limiting strip 4 has a reflective layer 6 on the upper surface of the main body 41. The reflective layer 6 can be coated on the upper surface of the main body 41 or laid on the main body 41. The reflective layer 6 is preferably made of a material capable of diffuse reflection. Its main purpose is to enable the reflective layer 6 on the main body 41 to diffusely reflect light under sunlight, thereby increasing photovoltaic power generation efficiency and avoiding light pollution. Therefore, materials that can achieve diffuse reflection are within the scope of protection of this application. The highest point of the main body 41 is lower than the highest point of the ridge 11. When sunlight shines obliquely on the ridge 11, the ridge 11 has a backlight surface compared to direct sunlight. The irradiated surface on the main body 41 will reflect sunlight to the backlight surface of the ridge 11, thereby increasing the amount of sunlight received by the main body 41. Therefore, the main body 41 is in the shape of an arc and V with the opening facing downwards, not only to facilitate the compression and deformation of the main body 41 by personnel, but also to increase the area of ​​the ridge 11 that receives light through reflection.

[0093] During the process of inserting the plug part 42 into the first plug area 21 and the second plug area 31, in order to ensure that the positions of the two plug parts 42 inserted into the first plug area 21 and the second plug area 31 are consistent with the preset positions, a limiting member 7 is fixedly connected to the side of the main body 41 near the second outer flange 13. A limiting hole 131 is opened on the side of the second outer flange 13 near the main body 41. The limiting hole 131 is used for the insertion of the limiting member 7. The end of the limiting member 7 inserted into the limiting hole 131 can be rod-shaped or plate-shaped. The shape of the limiting hole 131 matches the end of the limiting member 7 inserted into the hole.

[0094] As a preferred embodiment, if the limiting member 7 is rod-shaped, a first through hole for the wire harness to pass through is formed between adjacent limiting members 7. If the limiting member 7 is plate-shaped, a first through hole for the wire harness to pass through is provided on the limiting member 7. While allowing the wire harness to pass through for partitioning and sorting, it can also reduce the weight of the limiting member 7. In this embodiment, the limiting member 7 is preferably rod-shaped, and multiple limiting members 7 are distributed sequentially at intervals along the long side of the main body 41.

[0095] The implementation principle of a small tile structure in this application embodiment is as follows: when laying the tile body 1 on the roof, the first tile body 1 is first placed on the roof and fixed to the roof structure by screws or glue.

[0096] Subsequently, the second outward flange 13 on the next tile body 1 is inserted into the first insertion area 21 of the previous tile body 1. Then, the main body 41 is squeezed and placed between the first pressure strip 2 and the second pressure strip 3. When the limiting member 7 is inserted into the limiting hole 131, the personnel release the main body 41, and the two insertion parts 42 will be inserted into the first insertion area 21 and the second insertion area 31 respectively. Next, the personnel can connect the other tiles body 1 to the previous tile body 1 in sequence according to the above scheme.

[0097] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be included within the scope of protection of this application. In addition, the terms "up", "down", "high" and "low" described in this application are based on the orientation of the tile when it is placed horizontally.
