Referring to Figures 1 to 6, the embodiment of the present disclosure provides a lighting structure, including a light opening 11, a wall 2, a first fused waterproof board 3, a first waterproof cover sheet 4, and a lighting board 5.

As shown in Figures 1 to 6, a skylight 11 is formed on the roof 1. A fence 2 is provided along the circumference of the skylight 11 and protrudes from the roof 1. The first fused waterproofing sheet 3 includes a first main body 31, a first folded edge 32, and a second folded edge 33. The first main body 31 is provided along the circumferential outer surface of the fence 2. The first folded edge 32 is connected to the lower edge of the first main body 31 and overlaps the roof 1. The second folded edge 33 is connected to the upper edge of the first main body 31 and overlaps the upper end surface of the fence 2. The first waterproof covering sheet 4 is attached to the first folded edge 32 and the roof 1 along the outer edge of the first folded edge 32. The first waterproof covering sheet 4 is sealed to the first folded edge 32 and the roof 1, respectively. The edge of the skylight panel 5 overlaps the upper end surface of the fence 2 and is located above the second folded edge 33. The skylight panel 5 is fixedly connected to the second folded edge 33 and the upper end surface of the fence 2 by a first fastener M1.

In one embodiment, as shown in FIG1 , a skylight 11 is provided on the roof 1. For example, the skylight 11 can be provided at any location on the roof 1, and can be located in the middle of the roof structure. The shape of the skylight 11 can be square, circular, or oval. The location and shape of the skylight 11 can be determined based on the lighting requirements of the building and are not limited herein.

For example, the skylight 11 can be formed on one or more roof panels of the roof 1, or the skylight 11 can be formed by removing one or more roof panels from the roof 1, thereby forming a skylight 11 of a specific shape. For example, the skylight 11 can be formed by removing material from one of the roof panels 12 of the roof 1, or the roof 1 includes roof panels 12 formed by overlapping each other, and the skylight 11 can be formed by removing one or more roof panels 12, and the shape of the skylight 11 is adapted to the shape of the roof panels.

As shown in Figures 2 and 5, in one embodiment, a wall 2 is provided along the circumference of the skylight 11 and protrudes from the roof 1. The wall 2 is provided along the circumference of the skylight 11. For example, if the skylight 11 is square, the wall 2 forms a cube along the four sides of the skylight 11. For example, if the skylight 11 is circular, the wall 2 forms a cylindrical shape along the circumference of the skylight 11. The wall 2 protrudes from the outer surface of the roof 1, and the upper end surface of the wall 2 supports the skylight panel 5.

As shown in Figure 3, in one embodiment, the first fused waterproofing board 3 includes a first main portion 31, a first folded edge portion 32, and a second folded edge portion 33. The first main portion 31 is disposed along the circumferential outer surface of the enclosure wall 2. The first folded edge portion 32 is connected to the lower edge of the first main portion 31 and overlaps the roof 1. The second folded edge portion 33 is connected to the upper edge of the first main portion 31 and overlaps the upper end surface of the enclosure wall 2. The first main portion 31 of the first fused waterproofing board 3 covers the circumferential outer surface of the enclosure wall 2. The first folded edge portion 32 is located at the lower edge of the first main portion 31 and overlaps the outer surface of the roof 1. The second folded edge portion 33 is located at the upper edge of the first main portion 31 and overlaps the upper end surface of the enclosure wall 2. With this structure, the first fused waterproofing board 3 can seal the portion of the roof 1 adjacent to the enclosure wall 2, the enclosure wall 2, and the gap between the enclosure wall 2 and the roof 1, thereby improving the waterproof performance of the enclosure wall of the lighting structure.

It should be noted that the circumferential outer surface of the wall 2 in the embodiment of the present disclosure refers to the side facing away from the skylight 11, and the outer surface of the roof 1 can refer to the side facing outside the building.

In one embodiment, the first waterproof covering sheet 4 is attached to the first folded edge 32 and the roof 1 along the outer edge of the first folded edge 32. The first waterproof covering sheet 4 is sealed to the first folded edge 32 and the roof 1, respectively. The first waterproof covering sheet 4 can cover and seal the edge of the first folded edge 32, thereby preventing water seepage and leakage between the edge of the first folded edge 32 and the roof 1, and improving the waterproof performance between the first folded edge 32 and the roof 1.

Illustratively, the first waterproof covering sheet 4 is sealed to the first folded edge 32 and the roof 1, respectively. For example, the first waterproof covering sheet 4 can be sealed to the first folded edge 32 and the roof 1, respectively, using a sealant. In other embodiments, the first waterproof covering sheet 4 can also be sealed to the first folded edge 32 and the roof 1, respectively, by hot air welding. The method of sealing the first waterproof covering sheet 4 to the first folded edge 32 and the roof 1 is not limited herein.

As shown in Figures 3 and 4, in one embodiment, the edge of the skylight 5 overlaps the upper end surface of the enclosure 2 and is located above the second folded edge portion 33. The skylight 5 is fixedly connected to the second folded edge portion 33 and the upper end surface of the enclosure 2 by a first fastener M1. The skylight 5 is made of a transparent material and can be used for light transmission. The skylight 5 also needs to cover the skylight opening 11 to achieve waterproofing of the skylight opening 11. The shape of the skylight 5 is compatible with the skylight opening 11. For example, when the skylight opening 11 is square, the skylight 5 is square; when the skylight opening 11 is circular, the skylight 5 is circular. In addition, the size of the skylight 5 is larger than the size of the skylight opening 11, so that the edge of the skylight 5 can overlap the upper end surface of the enclosure 2.

For example, the skylight 5 can be made of glass. For example, the skylight 5 can be made of hollow glass. This provides high light transmittance, excellent sound insulation, and good thermal insulation. The skylight 5 can also be provided with an optical film, such as a sunshade film, to block sunlight when needed.

For example, the skylight 5 can also be made of acrylic, PC, or PP. Acrylic offers excellent transparency and chemical stability, and is relatively easy to process and shape. PC, also known as polycarbonate, is lightweight and offers excellent sound insulation. It should be noted that the specific material of the skylight 5 is not limited here and can be selected based on actual usage requirements.

For example, the skylight 5 is fixedly connected to the second folded edge portion 33 and the upper end face of the wall 2 by a first fastener M1. The second folded edge portion 33 is located outside the upper end face of the wall 2, and the edge of the skylight 5 overlaps above the second folded edge portion 33, and the second folded edge portion 33 is clamped between the edge of the skylight 5 and the upper end face of the wall 2. The first fastener M1 passes through the skylight 5 and the second folded edge portion 33 and partially penetrates into the upper end face of the wall 2, so that the skylight 5 is fixedly connected to the second folded edge portion 33 and the upper end face of the wall 2. With this arrangement, the second folded edge portion 33 improves the waterproof performance between the edge of the skylight 5 and the overlapping portion of the wall 2, preventing water seepage and leakage at the overlapping portion of the skylight 5 and the wall 2.

For example, the first fastener M1 may include a rivet, a self-tapping screw, a non-self-tapping screw, or other components that can play a role in fixing and connecting. For example, the second fastener may be a self-tapping screw for easy connection.

Exemplarily, the number of first fasteners M1 can be multiple, and multiple first fasteners M1 are evenly spaced along the outer peripheral side of the fence 2 and the light-transmitting board 5 to fix the edge of the light-transmitting board 5. This makes the overall structural strength and stability of the light-transmitting structure greater, improves the wind resistance of the light-transmitting structure, and ensures the reliability and stability of the light-transmitting board 5.

The lighting structure of the disclosed embodiment has a perimeter wall 2 protruding from the roof 1, disposed circumferentially around the skylight opening 11. The first main body 31 of the first fused waterproofing panel 3 is disposed along the circumferential outer surface of the perimeter wall 2. A first folded edge 32 is connected to the lower edge of the first main body 31 and overlaps the roof 1. A second folded edge 33 is connected to the upper edge of the first main body 31 and overlaps the upper end surface of the perimeter wall 2. A first waterproof covering sheet 4 is attached to the first folded edge 32 and the roof 1 along its outer edge, sealingly connecting the first folded edge 32 and the roof 1, respectively. In such a lighting structure, the outer surface and upper end surface of the wall 2 and the junction between the outer surface of the roof 1 and the wall 2 are covered by the first fused waterproof board 3, and the junction between the first folded edge 32 and the roof 1 is covered by the first waterproof covering sheet 4. Therefore, the wall 2 and the roof 1 of the lighting structure form a closed waterproof whole, avoiding water leakage at the wall 2 and the junction between the wall 2 and the roof 1. A second folded edge 33 is arranged between the lighting board 5 and the upper end surface of the wall 2 to avoid water leakage at the overlap position of the lighting board 5 and the wall 2. While realizing the light-transmitting lighting function of the lighting board 5, the airtightness of the connection between the lighting board 5 and the roof 1 is guaranteed, thereby improving the waterproof performance of the lighting structure.

In one embodiment, the first fused waterproof sheet 3 includes a metal sheet layer and a waterproof layer attached to the outer surface of the metal sheet layer 31. The waterproof layer of the first fused waterproof sheet 3 is made of thermoplastic polyolefin, and the first waterproof cover sheet 4 is also made of thermoplastic polyolefin. The outer surface of the roof 1 is made of thermoplastic polyolefin. The first waterproof cover sheet 4 is connected to the outer surface of the first fused waterproof sheet 3 by hot air welding. The first waterproof cover sheet 4 is also connected to the outer surface of the roof 1 by hot air welding.

Figure 7 is a schematic diagram of the structure of a first fused waterproofing panel according to an embodiment of the present disclosure. As shown in Figure 7 , the first fused waterproofing panel 3 comprises a first metal sheet 301 and a first waterproof layer 302 attached to the outer surface of the first metal sheet 301. The first waterproof layer 302 is made of thermoplastic polyolefin (TPO). The first waterproof layer 302 may be a TPO waterproof layer and may be attached to the outer surface of the first metal sheet 301 via an adhesive layer. The outer surface of the roof 1 is made of a waterproof layer, which is made of thermoplastic polyolefin. A predetermined gap is formed between the first waterproof covering sheet 4 and the outer surfaces of the first fused waterproofing panel 3 and the outer surface of the roof 1. The first waterproof covering sheet 4 is connected to the outer surfaces of the first fused waterproofing panel 3 and the outer surface of the roof 1 at the predetermined gap by hot air welding. With this connection method, the connection between the first waterproof covering sheet 4 and the outer surface of the first fused waterproof board 3 and the outer surface of the roof 1 is more secure and will not age due to wind and sun exposure, thereby avoiding water leakage between the first waterproof covering sheet 4 and the roof and the first fused waterproof board 3, and further improving the waterproof performance of the lighting structure.

For example, the width of the hot-air welded connection is greater than 40 mm. The width of the hot-air welded connection represents the effective dimension of the welded connection between the two side edges of the first waterproof cover sheet 4 and the roof and first fused waterproof sheet 3. Setting the width of the hot-air welded connection greater than 40 mm ensures the structural strength and stability of the connection between the first waterproof cover sheet 4, the roof, and the first fused waterproof sheet 3, thereby improving the waterproof performance of the first waterproof cover sheet 4. The specific width of the hot-air welded connection can be set based on actual usage requirements and is not limited here.

As shown in FIG. 2 and FIG. 5 , in one embodiment, the enclosure 2 includes a first enclosure portion 21 located at both ends of the daylight opening 11 in a first direction, and a second enclosure portion 22 located at both ends of the daylight opening 11 in a second direction.

Exemplarily, the first direction and the second direction are arranged to intersect. For example, the skylight 11 is square, the first wall portion 21 is located on two opposite sides of the skylight 11, and the second wall portion 22 is located on two other opposite sides of the skylight 11. The length of the first wall portion 21 matches the length of the skylight 11, and the length of the second wall portion 21 matches the length of the skylight 11. The first direction and the second direction are arranged perpendicularly.

Illustratively, the first fused waterproof panel 3 includes a metal sheet layer and a waterproof layer adhered to the outer surface of the metal sheet layer. The metal sheet layer and the waterproof layer are combined to improve the waterproof performance of the first fused waterproof panel 3. The lighting structure also includes a second fused waterproof panel 6, which includes a metal sheet layer and a waterproof layer adhered to the outer surface of the metal sheet layer. The membrane layer materials of the first and second fused waterproof panels 3 and 6 are the same and can be manufactured using the same process.

As shown in Figures 3 and 4, illustratively, the second fused waterproof board 6 includes a second main body portion 61 and a third folding portion 62. The second main body portion 61 is arranged on the outside of the first main body portion 31 along the first wall portion 21, that is, the second main body portion 61 is arranged on the outside of the waterproof layer of the first main body portion 31. The second main body portion 61 is connected to the corresponding first main body portion 31, and the second main body portion 61 is connected to the corresponding first main body portion 31 by screws. The lower end of the second main body portion 61 is bent in a direction away from the first main body portion 31 to form a tail portion, and the tail portion is inclined at an angle relative to the second main body portion 61, and the screw is arranged above the tail portion, so that water can flow away from the tail portion, avoiding moisture accumulation at the screw position and causing corrosion of the screw.

As shown in Figures 3 and 4 , for example, the second main body 61 extends upward and is higher than the skylight 5, and the third folded edge 62 is connected to the upper edge of the second main body 61 and blocks the skylight 5. The third folded edge 62 covers the skylight 5, and the second main body 61 and the third folded edge 62 cooperate to cover the overlap between the skylight 5 and the wall 2. The first fused waterproof board 3 and the second fused waterproof board 6 together form a waterproof system that protects the wall and the edge of the skylight, improving the waterproof performance of the skylight structure.

In one embodiment, the skylight 5 is fixedly connected to the second folded edge portion 33 and the upper end surface of the enclosure 2 by screws. The screws pass through the third folded edge portion 62, the skylight 5, and the second folded edge portion 33 to securely connect to the upper end surface of the enclosure 2. In this way, the second main portion 61 and the third folded edge portion 62 of the second fused waterproofing board 6 are both fixedly connected by screws, thereby improving the stability and reliability of the connection of the second fused waterproofing board 6.

The lighting structure of the disclosed embodiment forms a waterproof system covering the outer side surface of the fence 2 and the upper end surfaces of the lighting board and the fence through the cooperation of the first fused waterproof board 3 and the second fused waterproof board 6, thereby avoiding water leakage at the junction of the fence 2 and the fence 2 and the roof 1, ensuring the airtightness of the connection between the lighting board 5 and the roof 1, and improving the waterproof performance of the lighting structure.

As shown in FIG3 and FIG4, in one embodiment, the first wall portion 21 includes a first support 211 and a first wall portion 212. The first support 211 is located in the light opening 11, and the first support 211 is " " shape, the upper end surface of the first support 211 is flush with the outer surface of the roof 1. The two folded edges on the lower side of the first support 211 are fixedly connected to the purlin by screws. The first wall portion 212 is located on the upper end surface of the first support 211, and the first wall portion 212 is fixedly connected to the upper end surface of the first support 211. With this arrangement, the first wall portion 21 can be fixed to the purlin through the first support 211 and flush with the roof 1, and then the first wall portion 212 can be installed on the first support 211, thereby facilitating the installation and removal of the first wall portion 21.

For example, the groove of the first support 211 can be filled with insulation material, such as thermal insulation foam. The first support 211 and the purlin form a sealed space, and the thermal insulation foam is placed in the groove of the first support 211. This can avoid the cold bridge and thermal bridge effects of the first support 211, improve the thermal insulation performance of the lighting structure, and contribute to energy conservation and consumption reduction of the building.

As shown in Figures 3 and 4, in one embodiment, the first wall portion 212 includes a first metal plate 2121, which is a "C"-shaped metal plate. The first wall portion 212 also includes an insulation material 2122 filled in the first metal plate 2121, and the notch of the first metal plate 2121 faces outward.

For example, the first metal sheet 2121 may include a steel sheet or a galvanized steel sheet. The bottom surface of the first metal sheet 2121 is fixedly connected to the upper end surface of the first support 211, and the upper end surface of the first metal sheet 2121 is overlapped with the second folded edge portion 33 of the first fusion waterproof plate 3. The notch of the first metal sheet 2121 is arranged to face outward, that is, the notch of the first metal sheet 2121 is arranged to face the side away from the skylight 11, so that the side wall of the first metal sheet 2121 is arranged close to the side of the skylight 11. Therefore, the side wall of the first metal sheet 2121 can be seen from the perspective of indoor users of the building, thereby improving the indoor appearance of the first wall portion 212 and improving the overall aesthetics of the skylight structure.

For example, the thermal insulation material 2122 is thermal insulation cotton, and the thermal insulation material 2122 is filled in the groove of the first metal plate 2121. This arrangement can avoid the cold bridge and thermal bridge effects of the first metal plate 2121, improve the thermal insulation performance of the lighting structure, and help save energy and reduce consumption of the building.

It should be noted that the structure of the second wall portion 22 is the same as that of the first wall portion 21 , and the sizes of the first wall portion 22 and the second wall portion 21 are the same or different. The specific structure of the second wall portion 22 is not repeated here.

As shown in Figures 3 and 4 , in one embodiment, the second fused waterproof panel 6 further includes a fourth hem 63, which is connected to the edge of the third hem 62 and is arranged obliquely downward relative to the third hem 62. The second main body 61, the third hem 62, and the fourth hem 63 collectively form a cover over the top surface where the skylight panel and the surrounding wall overlap. This arrangement further enhances the waterproof protection provided by the second fused waterproof panel 6 at the overlap of the skylight panel 5, improving the waterproof performance of the skylight structure.

3 and 4 , for example, the fourth hem portion 63 is arranged obliquely downward relative to the third hem portion 62. The fourth hem portion 63 is arranged obliquely downward relative to the third hem portion 62, and the angle formed between the fourth hem portion 63 and the third hem portion 62 is an obtuse angle. The lower end of the fourth hem portion 63 abuts against the outer surface of the skylight 5, and the fourth hem portion 63 can guide water on the third hem portion 62 to flow out of the skylight 5.

FIG8 is a schematic cross-sectional view of a partial structure of a lighting structure according to an embodiment of the present disclosure. Referring to FIG2 and FIG8 , in one embodiment, the lighting structure further includes a support beam 7 positioned below the lighting panel 5. The support beam 7 extends in a first direction, with both ends of the support beam 7 fixedly connected to the inner surface of the first enclosure portion 21, and the lighting panel 5 is fixedly connected to the support beam 7.

Exemplarily, support beam 7 is a purlin, comprising a main beam body and fixed portions at either end of the main beam body. The fixed portions are bent relative to the main beam body, extending in a first direction. The fixed portions are screwed to the inner surface of first enclosure portion 21 at both ends. The skylight panel 5 is fixed to support beam 7 via screws. Multiple screws are spaced apart along the first direction, securing the skylight panel 5 to support beam 7 in the first direction. This arrangement ensures stable and reliable fixing of the skylight panel 5 and improves its wind-resistant performance.

As shown in Figure 8 , in one embodiment, the skylight panel 5 includes a flat portion 51 and a plurality of raised portions 52 projecting upward from the flat portion 51. The flat portion 51 abuts the outer surface of the roof panel 12. The plurality of raised portions 52 are spaced apart along a first direction and extend along a second direction. The raised portions 52 are fixedly connected to the support beam 7 via second fasteners M2.

Exemplarily, the skylight panel 5 is square in shape and covers the skylight opening 11. The first and second directions of the skylight panel 5 can represent the length and width of the skylight opening 11. The second fastener M2 passes through the top of the raised portion 52 and is fixedly connected to the support beam 7. The second fastener M2 can include a rivet, a self-tapping screw, a non-self-tapping screw, or other components that can provide a fixed connection. Exemplarily, the second fastener M2 can be a self-tapping screw for easier connection.

The skylight panel 5 of the disclosed embodiment is provided with a plurality of raised portions 52 spaced apart along a first direction and projecting upward from a flat portion 51. The raised portions 52 extend along a second direction and are fixedly connected to the support beam 7 via second fasteners M2. This arrangement improves the stability and reliability of the connection of the skylight panel 5 and enhances the wind resistance of the skylight structure. Furthermore, the skylight panel 5 is provided with a plurality of raised portions 52 projecting upward from a flat portion 51, allowing water to flow out of the groove formed by the raised portions and the flat portion, thereby preventing water from corroding the second fasteners M2 on the surface of the raised portions 52 and improving the waterproof performance.

It should be noted that the flat portion 51 can be understood as the flat portion of the outer surface of the skylight 5 relative to the roof panel 12, and the raised portion 52 can be understood as the raised portion of the skylight 5 relative to the outer surface of the roof panel 12. The cross-sectional shape of the raised portion 52 can be arc-shaped or trapezoidal. The specific shape of the raised portion 52 is not limited in the present embodiment and can be set according to actual usage requirements.

As shown in Figure 8, in one embodiment, a first raised portion of the raised portion 52 is provided above the first wall portion 21, the third folded portion 62 blocks the top of the first raised portion, and the first raised portion is confined between the fourth folded portion 63 and the second main body portion 61. The fourth folded portion 63 is inclined relative to the third folded portion 62. The first raised portion is provided above the first wall portion 21, that is, the first raised portion overlaps the top surface of the first wall portion 21, and the first raised portion is the edge portion of the skylight. In such a structure, the top of the first raised portion is covered and blocked by the third folded portion, and the two sides of the first raised portion are confined between the fourth folded portion 63 and the second main body portion 61. The second main body portion 61, the third folded portion 62, and the fourth folded portion 63 are integrally covered above the first raised portion, confining the first raised portion in a waterproof sealed space, thereby improving the waterproof performance of the first raised portion at the edge of the skylight.

As shown in Figure 6, in one embodiment, in the second direction, the lighting structure further includes a plug 53. The plug 53 matches the raised portion 51 and is located between the raised portion 51 and the second folded edge portion 33. The raised portion 51 and the plug 53 are fixed to the upper end surface of the second wall portion 22 via a second fastener M2. With this arrangement, the plug 53 can fill both ends of the raised portion 52 of the lighting panel 5 in the second direction, thereby preventing dust or rainwater from entering the room through the raised portion 52, thereby improving the waterproof performance of the lighting structure.

Exemplarily, the plugging piece 53 is located between the raised portion 51 and the second folded edge portion 33, and the plugging piece 53 is fixed to the upper end surface of the second wall portion 22 by a second fastener. The ends of each raised portion 51 are blocked by the plugging piece 53, and the plugging piece 53 can be a foam plug.

As shown in FIG6 , in one embodiment, a third fused waterproofing board 8 is further included. The third fused waterproofing board 8 includes a metal plate layer and a waterproof layer attached to the outer surface of the metal plate layer. The third fused waterproofing board 8 includes a third main portion 81 and a fifth folded edge portion 82. The third main portion 81 is disposed outside the first main portion 31 along the second wall portion 22 located on the upper side of the drainage direction. The third main portion 81 is connected to the first main portion 31 and extends upward and above the skylight 5. The fifth folded edge portion 82 is connected to the upper edge of the third main portion 81 and blocks the skylight 5. With this arrangement, the third main portion 81 is connected to the first main portion 31 and disposed outside the second wall portion 22, and the fifth folded edge portion 82 is connected to the upper edge of the third main portion 81 and blocks the skylight 5. Thus, the third fused waterproofing board 8 provides waterproof protection for the overlapping edge between the skylight 5 and the second wall portion 22.

As shown in FIG6 , the third fused waterproofing board 8 further includes, by way of example, a sixth folded edge 83 connected to the edge of the fifth folded edge 82. The sixth folded edge 83 is arranged obliquely downward relative to the fifth folded edge 82 and includes an opening slot for circumventing the protrusion 51. Thus, the sixth folded edge 83, the fifth folded edge 82, and the third main body 81 overlap the overlapping edge of the second wall portion 22 and the skylight panel, improving the waterproofing performance of the overlapping portion between the skylight panel and the second wall portion 22.

For example, the sixth folded edge 83 is tilted downward relative to the fifth folded edge 82. This tilt facilitates water on the fifth folded edge 82 to flow along the sixth folded edge 83 into the groove of the skylight. Furthermore, the sixth folded edge 83 is provided with a notch that avoids the raised portion 51. This further facilitates the installation of the third fused waterproof board 8 and the skylight board 5, and enhances the aesthetic appearance of the assembled third fused waterproof board and the skylight board 5.

As shown in Figure 1, in one embodiment, a roof 1 includes a plurality of roof panels 12 joined together along a first direction and a second direction. A skylight 11 is formed by removing one or more adjacent roof panels 12 in the first direction. This arrangement allows the skylight 11 to be formed by removing one or more adjacent roof panels 12 in the first direction. This eliminates the need for machining the skylight 11 on the roof panels 12, reducing the cost and difficulty of machining the roof panels. Furthermore, the size of the skylight 11 can be adjusted based on the number of roof panels 12 removed as needed, facilitating adjustments to the size of the skylight 11.

Figure 9 is a schematic cross-sectional view of a roof panel according to an embodiment of the present disclosure. Referring to Figure 9 , in one embodiment, in a first direction, the roof panel 12 includes a first end surface 121 and a second end surface 122 disposed opposite each other. The first end surface 121 includes a first region 1211 and a second region 1212, with the second region 1212 protruding relative to the first region 1211. The second end surface 122 includes a third region 1221 and a fourth region 1222, with the third region 1221 protruding relative to the fourth region 1222. The third region 1221 mates with the first region 1211, and the second region 1212 mates with the fourth region 1222, so that the first end surfaces 121 and second end surfaces 122 of two adjacent roof panels 12 can mate and overlap.

As shown in FIG9 , for example, the second region 1212 protrudes relative to the first region 1211, forming a stepped surface between the second region 1212 and the first region 1211. The third region 1221 protrudes relative to the fourth region 1222, forming a stepped surface between the third region 1221 and the fourth region 1222. After the first end surface 121 and the second end surface 122 are butted together, the second region 1212 and the third region 1221 are arranged in an overlapping manner.

It should be noted that the third region 1221 mates with the first region 1211, and the second region 1212 mates with the fourth region 1222. It can be understood that the third region 1221 can be aligned with the side of the first region 1211, with a sealant sealant provided between the third region 1221 and the first region 1211. The second region 1212 can be aligned with the side of the fourth region 1222, with a sealant sealant provided between the second region 1212 and the fourth region 1222.

2 to 4 , the lower folded edge of the first support 211 is located between the adjacent roof panel 12 and the purlin 9, the first fastening screw L1 passes through the second area 1212 of the roof panel 12 and the lower folded edge of the first support 211 and is fixed to the purlin 9, and the second fastening screw L2 passes through the third area 1221 of the roof panel 12 and the lower folded edge of the first support 211 and is fixed to the purlin 9.

In the disclosed embodiment of the skylight structure, the first fastening screw passes through the second region 1212 of the roof panel 12 and the lower hem of the first bracket 211 to secure it to the purlin 9. The second fastening screw L2 passes through the third region 1221 of the roof panel 12 and the lower hem of the first bracket 211 to secure it to the purlin 9. This simplifies installation of the roof panel, effectively reducing installation difficulty and improving construction efficiency. Furthermore, both the first fastening screw L1 and the second fastening screw L2 can simultaneously penetrate the metal sheeting on both sides of the roof panel, increasing connection strength, improving the roof panel's wind-up resistance, and ensuring the stability of the roof structure.

As shown in Figures 2 to 4 , in one embodiment, the first fastening screw L1 and the second fastening screw L2 are both covered by the first folded edge portion 32 of the corresponding first fusion waterproofing board 3. This arrangement forms a sealed space with the first folded edge portion 32 and the first support, within which the first fastening screw L1 and the second fastening screw L2 are located. This prevents liquid from flowing toward the first fastening screw L1 and the second fastening screw L2, further preventing water seepage at the location of the first fastening screw L1 and the second fastening screw L2, and further improving the waterproof performance of the roof structure.

Figure 10 is a schematic cross-sectional view of a roof panel overlap according to an embodiment of the present disclosure; Figure 11 is an enlarged schematic view of a roof panel overlap according to an embodiment of the present disclosure. Referring to Figures 10 and 11, in one embodiment, the second region 1212 and the third region 1221 are located outboard of the first region 1211 and the fourth region 1222. The outer surfaces of the third region 1221 and the second region 1212 form a recessed area relative to the outer surface of the roof panel 12. The fastening screws used to secure the roof panel 12 are all located in the recessed area, and the height of the upper end of the fastening screw is less than the depth of the recessed area, so that the upper end surface of the fastening screw does not exceed the outer surface of the roof panel 12. This arrangement allows the fastening screws to be formed within the recessed area, eliminating the need for the upper end of the fastening screw to be directly exposed to the outdoors, reducing the cold and thermal bridge effects of the fastening screws and preventing the formation of condensation at the upper end of the fastening screws.

As shown in Figure 1, in one embodiment, a roof 1 includes a plurality of roof panels 12 joined together along a first direction and a second direction. A skylight 11 is formed by removing one or more adjacent roof panels 12 in the second direction. This arrangement allows the skylight 11 to be formed by removing one or more adjacent roof panels 12 in the second direction. This eliminates the need for machining the skylight 11 on the roof panels 12, reducing the cost and difficulty of forming the roof panels. Furthermore, the size of the skylight 11 can be adjusted based on the number of roof panels 12 removed, facilitating adjustments to the size of the skylight 11.

As shown in Figure 6, in one embodiment, the end of the roof panel 12 adjacent to the skylight 11, near the skylight 11, is fixed to the purlin 9 via a third fastening screw L3. The third fastening screw L3 is covered by the first folded edge 32 of the corresponding first fusion waterproofing board 3. With this arrangement, the roof panel 12 is fixed to the purlin 9 via the third fastening screw L3, further improving the stability and reliability of the roof panel 12 connection and enhancing the wind resistance of the roof panel. Moreover, the first folded edge 32 of the first fusion waterproofing board 3 covers the third fastening screw L3, thereby preventing liquid from flowing toward the third fastening screw L3, further preventing water seepage at the location of the third fastening screw L3, and further improving the waterproof performance of the roof structure.

The present disclosure also provides a roof structure comprising any of the lighting structures of the present disclosure. The roof structure of the present disclosure can prevent water leakage at the joint between the lighting panel 5 and the wall 2, while ensuring the airtight connection between the lighting panel 5 and the roof 1 while achieving the light transmission and lighting function of the lighting panel 5, thereby improving the waterproof performance of the roof structure.
