As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

Figures 1 to 6 As shown, an embodiment of the present disclosure provides a daylighting structure, including a daylighting opening 11, a wall 2, a first fused waterproof board 3, a first waterproof covering sheet 4 and a daylighting board 5.

[0046] Reference Figures 1 to 6As shown, the daylighting opening 11 is opened on the roof 1. The enclosure 2 is arranged along the circumference of the daylighting opening 11 and protrudes from the roof 1. The first fusion waterproof board 3 includes a first main body 31, a first folding edge 32 and a second folding edge 33. The first main body 31 is arranged along the outer surface of the circumference of the enclosure 2. The first folding edge 32 is connected to the lower edge of the first main body 31 and overlaps the roof 1, and the second folding edge 33 is connected to the upper edge of the first main body 31 and overlaps the upper end surface of the enclosure 2. The first waterproof covering sheet 4 is attached to the first folding edge 32 and the roof 1 along the outer edge of the first folding edge 32, and the first waterproof covering sheet 4 is sealed and connected to the first folding edge 32 and the roof 1 respectively. The edge of the daylighting board 5 overlaps the upper end surface of the enclosure 2 and is located above the second folding edge 33. The daylighting board 5 is fixedly connected to the second folding edge 33 and the upper end surface of the enclosure 2 by the first fastener M1.

[0047] In one embodiment, Figure 1 As shown, the daylighting opening 11 is opened on the roof 1. For example, the daylighting opening 11 can be opened at any position of the roof 1, and the daylighting opening 11 can be set in the middle position of the roof structure. The shape of the daylighting opening 11 can be square, circular or elliptical, and the position and shape of the daylighting opening 11 can be set according to the lighting requirements of the building, which is not limited here.

[0048] Exemplarily, the daylighting opening 11 can be opened on one or more roof panels of the roof 1, or the daylighting opening 11 can also be formed by removing one or more roof panels of the roof 1, so that a daylighting opening 11 of a specific shape can be formed. For example, the daylighting opening 11 can be formed by cutting 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 daylighting opening 11 can also be formed by removing one or more roof panels 12, and the shape of the daylighting opening 11 is adapted to the shape of the roof panel.

[0049] like Figure 2 and Figure 5 As shown, in one embodiment, the wall 2 is arranged along the circumference of the skylight 11 and protrudes from the roof 1. The wall 2 is arranged along the circumference of the skylight 11. For example, when the skylight 11 is square, the wall 2 is enclosed along the four sides of the skylight 11 to form a cube. For example, when the skylight 11 is circular, the wall 2 is enclosed along the circumference of the skylight 11 to form a cylinder. The wall 2 is arranged to protrude from the outer surface of the roof 1, and the upper end surface of the wall 2 is used to support the skylight board 5.

[0050] like Figure 3As shown, in one embodiment, the first fusion waterproof board 3 includes a first main body 31, a first folding edge 32 and a second folding edge 33. The first main body 31 is arranged along the outer surface of the circumference of the enclosure 2. The first folding edge 32 is connected to the lower edge of the first main body 31 and overlaps the roof 1, and the second folding edge 33 is connected to the upper edge of the first main body 31 and overlaps the upper end surface of the enclosure 2. The first main body 31 of the first fusion waterproof board 3 covers the outer surface of the circumference of the enclosure 2, the first folding edge 32 is located at the lower edge of the first main body 31 and overlaps the outer surface of the roof 1, and the second folding edge 33 is located at the upper edge of the first main body 31 and overlaps the upper end surface of the enclosure 2. With such a structure, the first fusion waterproof board 3 can seal the part of the roof 1 close to the enclosure 2, the enclosure 2, and the gap between the enclosure 2 and the roof 1, thereby improving the waterproof performance of the enclosure of the lighting structure.

[0051] 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 may refer to the side surface facing outside the building.

[0052] In one embodiment, the first waterproof covering sheet 4 is attached to the first folded edge portion 32 and the roof 1 along the outer edge of the first folded edge portion 32, and the first waterproof covering sheet 4 is respectively sealed and connected to the first folded edge portion 32 and the roof 1. The first waterproof covering sheet 4 can cover and seal the edge of the first folded edge portion 32, thereby preventing water seepage and leakage between the edge of the first folded edge portion 32 and the roof 1, and improving the waterproof performance between the first folded edge portion 32 and the roof 1.

[0053] Exemplarily, the first waterproof covering sheet 4 is sealed and connected to the first folded edge portion 32 and the roof 1, respectively. For example, the first waterproof covering sheet 4 can be sealed and connected to the first folded edge portion 32 and the roof 1, respectively, by means of sealant. In some other embodiments, the first waterproof covering sheet 4 can also be sealed and connected to the first folded edge portion 32 and the roof 1, respectively, by means of hot air welding. The manner in which the first waterproof covering sheet 4 is sealed and connected to the first folded edge portion 32 and the roof 1 is not limited herein.

[0054] like Figure 3 and Figure 4As shown, in one embodiment, the edge of the skylight board 5 overlaps the upper end surface of the enclosure 2 and is located above the second folded edge portion 33, and the skylight board 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 board 5 is a transparent material that can be used for light transmission, and the skylight board 5 also needs to cover the skylight opening 11 to achieve waterproofing of the skylight opening 11, and the shape of the skylight board 5 is adapted to the skylight opening 11. For example, when the skylight opening 11 is square, the skylight board 5 is square, and when the skylight opening 11 is round, the skylight board 5 is round. And the size of the skylight board 5 is larger than the size of the skylight opening 11, so that the edge of the skylight board 5 can overlap the upper end surface of the enclosure 2.

[0055] Exemplarily, the lighting board 5 can be glass. For example, the lighting board 5 is hollow glass, so that the lighting board 5 has high light transmittance, high sound insulation effect, and good thermal insulation performance. An optical film such as a sunshade film can also be provided on the lighting board 5, so that sunlight can be blocked when needed.

[0056] Exemplarily, the lighting board 5 can also be an acrylic board, a PC board or a PP board. Acrylic boards have good transparency and chemical stability, and are relatively easy to process. PC boards are also called polycarbonate boards, which are light in weight and have good sound insulation performance. It should be noted that the specific material of the lighting board 5 is not limited here, and can be set according to actual use requirements.

[0057] Exemplarily, the lighting board 5 is fixedly connected to the second folded edge portion 33 and the upper end surface of the fence 2 by the first fastener M1. The second folded edge portion 33 is located outside the upper end surface of the fence 2, and the edge of the lighting board 5 overlaps above the second folded edge portion 33, and the second folded edge portion 33 is clamped between the edge of the lighting board 5 and the upper end surface of the fence 2. The first fastener M1 penetrates the lighting board 5, the second folded edge portion 33, and partially penetrates into the upper end surface of the fence 2, so that the lighting board 5 is fixedly connected to the second folded edge portion 33 and the upper end surface of the fence 2. With such a configuration, the second folded edge portion 33 improves the waterproof performance between the edge of the lighting board 5 and the overlapping portion of the fence 2, preventing water seepage and leakage at the overlapping position of the lighting board 5 and the fence 2.

[0058] 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.

[0059] Exemplarily, the number of first fasteners M1 can be multiple, and multiple first fasteners M1 are evenly spaced along the outer peripheral sides of the fence 2 and the skylight board 5 to fix the edge of the skylight board 5. This makes the overall structural strength and stability of the skylight structure greater, improves the wind resistance of the skylight structure, and ensures the reliability and stability of the skylight board 5.

[0060] In the lighting structure of the disclosed embodiment, a wall 2 protruding from the roof 1 is arranged in the circumferential direction of the lighting opening 11, and the first main body 31 of the first fusion waterproof plate 3 is arranged along the circumferential outer surface of the wall 2. The first folded edge portion 32 is connected to the lower edge of the first main body portion 31 and overlaps the roof 1, and the second folded edge portion 33 is connected to the upper edge of the first main body portion 31 and overlaps the upper end surface of the wall 2. The first waterproof covering sheet 4 is attached to the first folded edge portion 32 and the roof 1 along the outer edge of the first folded edge portion 32, and the first waterproof covering sheet 4 is sealed and connected to the first folded edge portion 32 and the roof 1 respectively. In such a lighting structure, the outer surface and the 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, so that 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, and 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.

[0061] In one embodiment, the first fused waterproof board 3 includes a metal plate layer and a waterproof layer attached to the outer surface of the metal plate layer 31, the material of the waterproof layer of the first fused waterproof board 3 includes thermoplastic polyolefin, and the material of the first waterproof covering sheet 4 includes thermoplastic polyolefin.

The material of the outer surface of the roof 1 includes a waterproof layer, and the material of the waterproof layer of the roof 1 includes thermoplastic polyolefin. A preset gap is formed 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, and 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 are connected by hot air welding at the preset gap. In 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 firm, and will not age with wind and sun, 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.

[0063] Exemplarily, the width of the hot air welding connection is greater than 40 mm. The width of the hot air welding connection can represent the effective size of the welding connection between the two side edges of the first waterproof covering sheet 4 and the roof and the first fused waterproof board 3. The width of the hot air welding connection is set to be greater than 40 mm, which can ensure the structural strength and stability of the connection between the first waterproof covering sheet 4 and the roof and the first fused waterproof board 3, and improve the waterproof performance of the first waterproof covering sheet 4. The specific size of the width of the hot air welding connection can be set according to actual use requirements and is not limited here.

For example, the daylighting opening 11 is square, the first wall portion 21 is located at two opposite sides of the daylighting opening 11, the second wall portion 22 is located at two other opposite sides of the daylighting opening 11, the length of the first wall portion 21 matches the daylighting opening 11, the length of the second wall portion 21 matches the daylighting opening 11, and the first direction and the second direction are arranged vertically.

[0066] Exemplarily, the first fused waterproof board 3 includes a metal plate layer and a waterproof layer attached to the outer surface of the metal plate layer.

The lighting structure also includes a second fused waterproof board 6, and the second fused waterproof board 6 includes a metal plate layer and a waterproof layer attached to the outer surface of the metal plate layer. The membrane material of the first fused waterproof board 3 and the second fused waterproof board 6 is the same, and the first fused waterproof board 3 and the second fused waterproof board 6 can be prepared and formed by the same process.

[0069] In one embodiment, the lighting board 5 is fixedly connected to the second folded edge portion 33 and the upper end surface of the wall 2 by screws. The screws pass through the third folded edge portion 62, the lighting board 5 and the second folded edge portion 33 and are fixedly connected to the upper end surface of the wall 2, so that the second main body portion 61 and the third folded edge portion 62 of the second fusion waterproof board 6 are fixedly connected by screws, thereby improving the stability and reliability of the connection of the second fusion waterproof board 6.

[0070] 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.
