Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In the entire specification and claims, the term "comprising" is an open term, which should be interpreted as "including but not limited to". "Approximately" means that the skilled in the art can solve the technical problems within a certain error range and basically achieve the technical effects. In addition, in the embodiments of the present application, multiple means two or more. Those skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of different embodiments or examples without contradiction.

[0040] In order to make the building have better lighting conditions, a light skylight is usually opened on the roof. In order to avoid water leakage of the light skylight, a skylight assembly corresponding to the position of the light skylight needs to be installed, so as to facilitate the installation of the glass window and other sealing members.

[0041] The existing skylight assembly is divided into multiple independent metal members during installation, so the installation process of the skylight assembly is complex, and the connection of the skylight assembly and the roof panel is not conducive, and the sealing of the connection is easy to fail, which increases the risk of roof leakage.

[0042] In order to solve the above technical problems, see Figure 1 and Figure 3In one embodiment of the present application, a roof skylight node system is provided, which comprises a roof body 1 and a skylight assembly 2. The roof body 1 comprises a roof panel 11, and the roof body 1 is provided with an opening 100, and the skylight assembly 2 is connected to the roof body 1 corresponding to the opening 100. Generally, the roof body 1 further comprises roof purlins 12 and a thermal insulation layer 13. A plurality of roof purlins 12 are combined into a roof purlin frame, and the thermal insulation layer 13 is bonded to the roof purlin frame, and then the roof panel 11 is laid on the thermal insulation layer 13. The opening 100 on the roof body 1 can be a through hole formed by cutting the thermal insulation layer 13 and the roof panel during on-site construction, or it can be a through hole reserved when laying the thermal insulation layer 13 and the roof panel. The skylight assembly 2 can be connected to the roof purlin 12 corresponding to the opening 100, or it can be connected to the thermal insulation layer 13 corresponding to the opening 100.

[0043] Further, referring to Figure 2 and Figure 3 , the skylight assembly 2 is a square structure, and the skylight assembly 2 comprises a water-facing side 21, a backwater side 22, and two side edges 23. A water guide plate 24 is provided on one side of the water-facing side 21, and a connecting portion 25 is provided on the backwater side 22. The water-facing side 21 of the skylight assembly 2 can be considered as the side that is impacted by the flowing rainwater. The backwater side 22 is arranged opposite to the water-facing side 21.

[0044] Generally, a plurality of roof panels 11 on the roof body 1 are laid in one direction, and different edges of the skylight assembly 2 will be connected to different sides of different roof panels 11. The water guide plate 24 is connected to the first roof panel 101 on one side of the water-facing side 21, the second roof panel 102 on one side of the backwater side 22 is connected to the connecting portion 25, and the third roof panel 103 on one side of the side edge 23 is connected to the side edge 23.

[0045] It should be noted that the first roof panel 101, the second roof panel 102, and the third roof panel 103 can be the same roof panel, or they can be different roof panels. For example, when the opening 100 is formed in the middle of the same roof panel 11, then the roof panels 11 around the skylight assembly 2 are the same roof panel 11. For example, when the opening 100 is reserved after a plurality of different roof panels 11 are spliced, then the roof panels 11 around the skylight assembly 2 are different roof panels 11.

[0046] In the technical scheme provided in the embodiments of the present application, the water-facing side 21 of the skylight assembly 2 is provided with a water guide plate 24, and the water-leaving side 22 is provided with a connecting portion 25, the water guide plate 24 and the connecting portion 25 are in an integrated structure with the skylight assembly 2, and in the installation process of the skylight assembly 2, the installation construction steps are simplified, and the installation efficiency is high. In addition, the first roof panel 101 on one side of the water-facing side 21 can be connected with the water guide plate 24, the second roof panel 102 on one side of the water-leaving side 22 can be connected with the connecting structure, and the third roof panel 103 on one side of the side edge 23 can be connected with the side edge 23, thereby effectively improving the sealing performance of the connection of each roof panel with different sides of the skylight assembly 2, and the water leakage hidden danger of the roof is effectively controlled.

[0047] In one of the embodiments provided in the present application, referring to Figure 1 , the roof body 1 is in an inclined state, the water-facing side 21 is located at the upstream of the roof body 1, and the water-leaving side 22 is located at the downstream of the roof body 1; in a rainy day, the rainwater can flow along the inclined direction of the roof body 1 from the upstream to the downstream of the roof body 1. The water guide plate 24 extends from the edge of the water-facing side 21 in the opposite direction of the inclined direction and towards the upstream, and the rainwater flowing along the roof can impact on the water guide plate 24. In the technical scheme provided in the present application, the water guide plate 24 can be considered to be arranged at the upstream of the skylight assembly 2, so that when a large amount of rainwater washes the skylight assembly 2, the water guide plate 24 can provide better waterproof effect due to the better sealing performance of the connection between the water guide plate 24 and the roof body 1.

[0048] Further, referring to Figure 1 , the water guide plate 24 is connected to the lower side of the first roof panel 101 through the first fastening assembly 3. The end of the water guide plate 24 is inserted into the lower side of the first roof panel 101. At the connection joint of the water guide plate 24 and the first roof panel 101, the roof body 1, the water guide plate 24 and the first roof panel 101 are stacked in sequence. The inclination angle of the roof body 1, the inclination angle of the water guide plate 24 and the inclination angle of the first roof panel 101 are the same. The second roof panel 102 is inserted into the connecting portion 25, and the second roof panel 102 is connected to the connecting portion 25 through the second fastening assembly 4. Specifically, the connecting portion 25 is an inner recess structure on the water-leaving side 22, the shape of the inner recess structure matches the shape of the wave crest 111 of the second roof panel 102, when the second roof panel 102 is connected to the water-leaving side 22, the wave crest 111 structure at the end of the second roof panel 102 is inserted into the inner recess structure, and the wave trough 112 structure at the end of the second roof panel 102 is located below the water-leaving side 22 and is pressed on the roof body 1 by the water-leaving side 22.

[0049] In the technical solution of the present application, part of the second roof panel 102 is pressed below the backwater edge 22, another part is connected in the connecting part 25, and the connecting node of the second roof panel 102 and the backwater edge 22 is also inclined with the roof body 1. Rainwater flowing from upstream is difficult to flow upward into the connecting node of the second roof panel 102 and the backwater edge 22, and it can be considered that the second roof panel 102 is located below the skylight assembly 2. Even if rainwater enters the connecting node of the second roof panel 102 and the backwater edge 22, the rainwater in this part will quickly flow away along the inclined second roof panel 102. The entire roof skylight node system has good waterproof effect.

[0050] Referring to Figure 1 and Figure 4 In an embodiment provided by the present application, the first fastening assembly 3 includes a lap strip 31 and a first fastener 32. The lap strip 31 is arranged on the first roof panel 101, and the first fastener 32 is connected to the roof body 1 through the lap strip 31, the first roof panel 101 and the water guide plate 24. The lap strip 31 on the first roof panel 101 can disperse the fastening force of the first fastener 32, so that the first roof panel 101 and the water guide plate 24 are more tightly attached, and rainwater is not easy to enter the roof body 1 through the connecting gap between the first roof panel 101 and the water guide plate 24.

[0051] The first fastener 32 can be a self-tapping screw. A through hole is arranged on the lap strip 31. In the field construction, a hole is first drilled on the first roof panel 101 and the water guide plate 24 by a drilling device, and then the self-tapping screw passes through the through hole on the lap strip 31, the through hole on the first roof panel 101 and the through hole on the water guide plate 24 in sequence, and is connected to the roof body 1 (the thermal insulation cotton layer 13). In order to avoid leakage of the through hole on the first roof panel 101 and the through hole on the water guide plate 24, a waterproof piece 33 is arranged between the first roof panel 101 and the water guide plate 24. The waterproof piece 33 includes but is not limited to a butyl tape, a waterproof rubber and a waterproof coating. The waterproof piece can effectively fill the gap between the self-tapping screw and the first roof panel 101 and the water guide plate 24, and effectively avoid water leakage.

[0052] Referring to Figure 2 and Figure 6From the cross section of the roof panel, it can be considered that the roof panel wave crest 111 structure is convex, the roof panel wave trough 112 structure is flat, and the water guide plate 24 is a flat plate. Therefore, when the roof panel is connected with the water guide plate 24, the roof panel wave trough 112 structure can be connected to the water guide plate 24, and the roof panel wave crest 111 structure protrudes above the water guide plate 24. The gap between the end of the wave crest 111 structure and the water guide plate 24 will affect the sealing of the roof skylight node system. Similarly, in addition to the first roof panel 101 connected with the water guide plate 24, the second roof panel 102 connected with the backwater side 22 also has the same problem.

[0053] In order to solve this problem, in an embodiment provided in the present application, the roof skylight node system further comprises a plug 6, the shape of the plug 6 matches the shape of the roof panel wave crest 111 structure, and the plug 6 is arranged at the end of the first roof panel 101 and the second roof panel 102 and is connected in the wave crest 111 of the first roof panel 101 and the second roof panel 102. The plug 6 can fill the gap between the first roof panel 101 and the water guide plate 24, so as to achieve the effect of sealing the end of the first roof panel 101. In addition, the plug 6 in the second roof panel 102 can fill the gap between the second roof panel 102 and the bottom of the backwater side 22, so as to achieve the effect of sealing the end of the second roof panel 102.

[0054] When the rainwater flows from upstream along the roof panel, it will directly impact on the water side 21. If the flow of rainwater is large, the force acting on the water side 21 will also be large. In an embodiment provided in the present application, referring to Figure 1 and Figure 3 , the skylight node system further comprises a shunt component 5, which is arranged between the water side 21 and the water guide plate 24. The shunt component 5 can shunt the rainwater flowing from upstream, effectively avoiding the rainwater directly impacting on the water side 21 of the skylight component 2. The shunt component 5 can be an integral structure with the skylight component 2, that is, when the skylight component 2 is prefabricated in the factory, the shunt component 5 is connected with the skylight component 2 to form an integral structure. The shunt component 5 can also be connected to the skylight component 2 through on-site construction during installation of the skylight component 2, and the connection mode of the shunt component 5 and the skylight component 2 can be welding, bonding, buckle connection or a combination of multiple modes. For example, the shunt component 5 is first connected with the skylight component 2 through spot welding, and then the sealant 34 is filled into the connection gap between the shunt component 5 and the skylight component 2.

[0055] In one embodiment, in order to improve the distribution effect of the distribution assembly 5, the distribution assembly 5 has a ridge structure 53. The distribution assembly 5 includes a first distribution plate 51 and a second distribution plate 52, and the two sides of the first distribution plate 51 and the second distribution plate 52 are connected with the water-facing side 21 and the water guide plate 24 respectively, and the ridge structure 53 is located at the connection of the first distribution plate 51 and the second distribution plate 52. Specifically, the first distribution plate 51 and the second distribution plate 52 can be an integral structure, and a complete metal plate is bent in the middle to form the ridge structure 53. The left side of the ridge structure 53 is the first distribution plate 51, and the right side of the ridge structure 53 is the second distribution plate 52. In addition, the distribution assembly 5 can also be a wedge, for example, a plastic wedge, which can be bonded to the water guide plate 24.

[0056] The materials of the distribution assembly 5 and the skylight assembly 2 include but are not limited to stainless steel, aluminum alloy, aluminum-magnesium alloy, galvanized steel, etc. In one specific construction process, the distribution assembly 5 and the skylight assembly 2 are respectively preformed by stainless steel material. After the skylight assembly 2 is installed on the roof body 1, the first distribution plate 51 and the second distribution plate 52 are respectively connected with the water-facing side 21 and the water guide plate 24 by spot welding, and then the gap between the distribution assembly 5 and the water-facing side 21 and the water guide plate 24 is filled with sealant 34. This construction process is simple and efficient, and the sealing performance also meets the requirements.

[0057] Referring to Figure 5 In one embodiment provided in the present application, the roof skylight node system further includes a first flashing member 7, which is arranged at the connecting node of the second roof panel 102 and the connecting portion 25; the first flashing member 7 includes a first folded edge 71 and a second folded edge 72, the first folded edge 71 is located below the second roof panel 102, and the second folded edge 72 is connected to the inner side of the water-away side 22. The second fastening assembly 4 includes a second fastener 41 and a waterproof pad 42, and the second fastener 41 can be a self-tapping screw. When the second roof panel 102 is inserted into the connecting portion 25, the second fastener 41 is connected to the roof body 1 through the second roof panel 102, and the waterproof pad 42 is arranged between the second roof panel 102 and the roof body 1, which can effectively prevent rainwater from penetrating into the roof body 1 through the pores after the self-tapping screw penetrates through the second roof panel 102. The waterproof pad 42 includes but is not limited to butyl tape, waterproof rubber, waterproof paint, etc.

[0058] In order to facilitate the installation of the skylight assembly 2, the roof body 1 further includes a sliding rail assembly 8, which is arranged on the roof body 1 corresponding to the opening 100. The bottom ends of the water-facing side 21, the water-away side 22 and the side edge 23 are respectively connected with the sliding rail assembly 8. When the skylight assembly 2 is installed, the skylight assembly 2 can slide on the sliding rail assembly 8 to align with the opening 100 on the roof body 1, which can effectively improve the installation accuracy of the skylight assembly 2.

[0059] As mentioned above, the second fastener 41 passes through the second roof panel 102 and connects to the roof body 1. Since the backwater edge 22 is located above the sliding track assembly 8, the second fastener 41 will directly connect to the sliding track assembly 8 after passing through the second roof panel 102. See also... Figure 1 In addition, the roof skylight node system also includes a third fastener 43, which passes through the bottom edge of the water-facing edge 21 and is connected to the sliding track assembly 8 on the lower side of the water-facing edge 21.

[0060] See Figure 6 The roof panel 1 consists of multiple roof panels spliced ​​together in the same direction. The ends of the roof panels, which have crest 111 and trough 112 structures, connect to the water-facing side 21 and the back side 22. The straight edge of the roof panel connects to the side 23 of the skylight assembly 2. To improve the stability of the connection between the third roof panel 103 and the side 23 of the skylight assembly 2, in one embodiment provided in this application, the edge of the third roof panel 103 has an upward-turning structure 9. The third roof panel 103 extends from the outer side of the side 23 to the inner side of the side 23, and the upward-turning structure 9 is located on the inner side of the side 23. The upward-turning structure 9 not only prevents the third roof panel 103 from detaching from the side 23 of the skylight assembly 2, but also serves a waterproofing function. In a specific embodiment, the upward-turning height of the upward-turning structure 9 is 15 mm, and the upward-turning structure 9 is fitted to the inner side of the side 23 of the skylight assembly 2. Side 23 is connected to the roof body 1 by self-tapping screws. A sliding track assembly 8 is also provided below side 23. A waterproof pad 42 is provided between side 23 and sliding track assembly 8. The self-tapping screw passes through the waterproof pad 42 and connects to the sliding track assembly 8. Sealant 34 is also applied to the outside of the connection between the third roof panel 103 and side 23, thereby effectively improving the waterproof performance of side 23.

[0061] Furthermore, to improve the wind resistance of the skylight assembly 2, the roof skylight node system also includes a side clip 10. One end of the side clip 10 is connected to the inner side of the side 23, and the other end of the side clip 10 is connected to the roof body 1. Specifically, the hook structure at one end of the side clip 10 hooks onto the inner side of the side 23, and the other end of the side clip 10 is fastened to the roof body 1 by a self-tapping screw.

[0062] In summary, the water guide plate and connecting parts are integrated with the skylight assembly, simplifying the installation process and increasing efficiency. Furthermore, the first roof panel can be connected to the water guide plate, the second roof panel to the connecting parts, and the third roof panel to the side panels, effectively improving the sealing of the connections between the roof panels and the skylight assembly on different sides, thus effectively controlling the potential for roof leaks.
