DETAILED DESCRIPTION

[0030] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0031] With the advancement and development of science and technology, metal has become a widely used material in the construction industry, especially in the metal roofing industry. Metal steel roofs have become the preferred choice of many users. The waterproofness of metal roofs has a profound impact on metal roofs. Currently, the most common waterproofing measures are to use sealants or welding to waterproof the roof through the flashing board. However, due to the expansion and contraction of metal roofs in the natural environment, gaps may form between the roof and the flashing board, causing roof leaks and affecting indoor production and life.

[0032] The roof skylight node structure according to the first embodiment of the present application is described below with reference to Figures 1 to 5.

[0033] Figure 1 shows a schematic cross-sectional view of a roof skylight structure 10 according to an embodiment of the present application; Figure 2 shows an enlarged view of the circled portion A in Figure 1. As shown in Figures 1 and 2, the roof skylight node structure includes a waterproof membrane 100, a folded plate 200, and a first waterproof cover sheet 300.

[0034] A portion of the waterproofing coiled material 100 is used to connect the roof panel 800, and another portion of the waterproofing coiled material 100 is used to connect the skylight 900. Exemplarily, the roof panel 800 can be a thermoplastic polyolefin metal plate (fusion tile). The waterproofing coiled material 100 and the roof panel 800, as well as the waterproofing coiled material 100 and the skylight keel, can be connected by hot air welding. After welding, the waterproofing coiled material 100 can form a complete waterproof surface, thereby preventing the roof from leaking. Hot air welding is a method of heating plastic weldment and welding rod with preheated compressed air or inert gas to make them reach a viscous state and weld under a small pressure.

[0035] Optionally, the waterproof membrane 100 can be a thermoplastic polyolefin waterproof membrane, which is a new type of waterproof membrane made of a thermoplastic polyolefin (TPO) synthetic resin that uses advanced polymerization technology to combine ethylene propylene rubber and polypropylene as the base material, and adds antioxidants, anti-aging agents, and softeners. It can also be made of polyester fiber mesh cloth as the internal reinforcement material to make an enhanced waterproof membrane, which is a synthetic polymer waterproof membrane type waterproof product.

[0036] A portion of the folding plate 200 is connected to the above-mentioned portion of the waterproof membrane 100 via a first fastener 210. The first fastener 210 is disposed near the skylight 900, and another portion of the folding plate 200 is disposed between the waterproof membrane 100 and the skylight 900. For example, the folding plate 200 can be bent by a bending machine. The waterproof membrane 100 is attached to the outer surface of the folding plate 200. The folding plate 200 can be made of a galvanized steel plate to ensure that the waterproof membrane 100 can be better attached to the folding plate 200. By providing the folding plate 200, an effective supporting effect can be provided for the waterproof membrane 100, thereby improving the structural strength of the roof skylight node structure. The first fastener 210 can be located at a concave corner position, and the method of fixing with the first fastener 210 makes the roof skylight node structure simple and convenient to process. The first fastener 210 can be a U-shaped fixing member.

[0037] The first waterproof covering sheet 300 is fixed to the side of the waterproof membrane 100 facing away from the folding plate 200, and covers the first fastener 210. The first waterproof covering sheet 300 covers the waterproof membrane 100 and is sealed therewith. For example, the first waterproof covering sheet 300 can be fixed to the waterproof membrane 100 using hot-air welding. This effectively prevents the first fastener 210 from being exposed and exposed to the natural environment, thereby preventing the first fastener 210 from rusting or falling off, thereby preventing roof leaks. Furthermore, the hot-air welding connection is less susceptible to aging due to the natural environment, ensuring the reliability and stability of the connection and extending the life of the roof structure.

[0038] According to the roof skylight node structure of the embodiment of the present application, the waterproof membrane 100 can form a sealed waterproof whole between the roof panel 800 and the skylight 900, thereby preventing water leakage. In addition, the folding plate 200 can provide effective support, thereby improving the structural strength and stability of the roof skylight 900 node. It also allows the waterproof membrane 100 to be attached to the folding plate 200, preventing water accumulation caused by the waterproof membrane 100 sinking. At the same time, the first waterproof cover sheet 300 prevents the first fastener 210 from being exposed, thereby preventing the first fastener 210 from rusting or falling off, further improving the waterproof performance of the roof skylight node structure.

[0039] Figure 3 shows an enlarged view of the circled portion B in Figure 1. In one embodiment, as shown in Figures 1 and 3, another portion of the waterproof membrane 100 is connected to the skylight 900 via a second fastener 110, which is fixed to the side of the skylight 900 facing away from the roof panel 800. Therefore, since the side of the skylight 900 facing the roof panel 800 is the water-facing side, by fixing the second fastener 110 to the side of the skylight 900 facing away from the roof panel 800, the waterproof membrane 100 can effectively cover the water-facing side of the skylight 900, so that the roof panel 800 and the skylight 900 form a closed whole, preventing water from invading between the waterproof membrane 100 and the folding plate 200 or between the folding plate 200 and the skylight 900, ensuring that the roof skylight node structure has good waterproof performance. At the same time, the second fastener 110 does not need to be in contact with the external natural environment, thereby preventing the second fastener 110 from rusting or falling off due to the influence of rain and wind, thereby improving the long-term reliability of the roof skylight node structure.

[0040] In one embodiment, as shown in Figures 1 and 3, the roof skylight node structure further includes a closing bead 400. The closing bead 400 is disposed on the side of the waterproof membrane 100 facing away from the skylight 900. A second fastener 110 passes through the closing bead 400 and the waterproof membrane 100 to securely connect to the skylight 900. Thus, by providing the closing bead 400, it can compress the edge of the waterproof membrane 100, preventing damage to the edge of the waterproof membrane 100, thereby extending the service life of the waterproof membrane 100 and improving waterproof reliability. Furthermore, the second fastener 110 securely secures the closing bead 400 to the skylight 900, further ensuring the waterproof performance of the roof skylight node structure.

[0041] In one embodiment, as shown in Figures 1 and 2, the roof skylight node structure further includes a support member 500, which is disposed below the end of the roof panel 800 near the skylight 900. The support member 500 is located on the side of the folded plate 200 that faces away from the waterproof membrane 100. As shown in Figure 2, in the vertical direction, the folded plate 200 is located between the roof panel 800 and the support member 500, and the roof panel 800 and the folded plate 200 are connected to the support member 500 via a third fastener 510. For example, the support member 500 may be a support angle steel, and the third fastener 510 may be a self-tapping screw, etc.

[0042] In this embodiment, by providing the above-mentioned support member 500, the support member 500 can be supported on the end of the roof panel 800. At the same time, the third fastener 510 can prevent the end of the roof panel 800 from warping, thereby improving the supporting strength of the roof panel 800.

[0043] In one embodiment, as shown in Figures 1 and 2, the roof skylight node structure may further include a second waterproof covering sheet 600. One end of the second waterproof covering sheet 600 (e.g., the left end in Figure 2) is connected to the roof panel 800, and the other end of the second waterproof covering sheet 600 (e.g., the right end in Figure 2) is connected to the waterproof membrane 100. The second waterproof covering sheet 600 covers the third fastener 510. The waterproof membrane 100 and the second waterproof covering sheet 600 may be the same membrane. For example, the second waterproof covering sheet 600 and the waterproof membrane 100 may be fixed using hot air welding. Thus, the second waterproof covering sheet 600 can effectively prevent the head of the third fastener 510 from being exposed, protecting the third fastener 510 from contact with the natural environment. This can prevent the third fastener 510 from rusting or falling off due to rain and wind, further preventing roof leaks. At the same time, the gap between the roof panel 800 and the folding plate 200 is also protected from erosion.

[0044] FIG4 shows a schematic cross-sectional view of a roof skylight node structure according to an embodiment of the present application from another angle; FIG5 shows an enlarged view of the circled portion C in FIG4 . The roof panel 800 of the embodiment of the present application adopts a fused tile. The roof panel 800 has a wavy structure and upwardly protruding wave crests. As shown in FIG4 and FIG5 , the roof skylight node structure further includes a third waterproof covering sheet 700. One end of the third waterproof covering sheet 700 (e.g., the left end in FIG5 ) is connected to the wave crest of the roof panel 800, and the other end of the third waterproof covering sheet 700 (e.g., the right end in FIG5 ) is connected to the waterproof membrane 100. For example, the third waterproof covering sheet 700 and the waterproof membrane 100 can be fixed by hot air welding.

[0045] In this embodiment, by using the third waterproof covering sheet 700 to connect with the waterproof membrane 100 at the crest position of the roof panel 800, the construction method of the crest position of the roof panel 800 is simplified, the construction efficiency is improved, and the difficulty of subsequent repairs is reduced.

[0046] In an optional embodiment, the thickness of the folding plate 200 can be 0.8 mm to 1.2 mm (inclusive). For example, the thickness of the folding plate 200 can be 1 mm. Specifically, for example, if the thickness of the folding plate 200 is less than 0.8 mm, the thickness of the folding plate 200 is too small and may not effectively support the waterproof membrane 100. If the thickness of the folding plate 200 is greater than 1.2 mm, the thickness of the folding plate 200 is too large, resulting in a heavy weight and high cost.

[0047] In this embodiment, by making the thickness of the folding plate 200 0.8mm to 1.2mm, it can effectively support the waterproof membrane 100 and prevent water accumulation in the groove of the waterproof membrane 100, while reducing the weight of the folding plate 200, thereby reducing the cost of the roof skylight node structure.

[0048] A roof skylight structure 10 according to an embodiment of the second aspect of the present application includes a roof panel 800, a skylight 900, and a roof skylight node structure according to any of the aforementioned embodiments. The skylight 900 is spaced apart from the roof panel 800. A first fastener 210 of the roof skylight node structure is disposed between the roof panel 800 and the skylight 900.

[0049] According to the roof skylight structure 10 of the embodiment of the present application, by adopting the above-mentioned roof skylight node structure, the waterproof membrane 100 can form a sealed waterproof whole between the roof panel 800 and the skylight 900, thereby preventing water leakage. In addition, the waterproof membrane 100 can be fixed to the folding plate 200 at the internal corner position via the first fastener 210, thereby improving the structural strength and stability of the roof skylight 900 node. The waterproof membrane 100 can also be attached to the folding plate 200, preventing water accumulation caused by the waterproof membrane 100 sinking. At the same time, the first waterproof cover sheet 300 can prevent the first fastener 210 from being exposed, thereby preventing the first fastener 210 from rusting or falling off, further improving the waterproof performance of the roof skylight node structure.

[0050] In an optional embodiment, the distance between the roof panel 800 and the skylight 900 can be 100 mm to 200 mm (inclusive). For example, FIG1 is a cross-sectional schematic diagram of the roof skylight structure 10. During rainfall, rainwater flows in a direction perpendicular to the paper. At this angle, the distance a between the roof panel 800 and the skylight 900 can be 100 mm. FIG4 is a longitudinal cross-sectional schematic diagram of the roof skylight structure 10. During rainfall, rainwater flows downward along the roof slope. At this angle, the distance b between the roof panel 800 and the skylight 900 can be 200 mm.
