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 a person of ordinary skill in the art without creative work fall within the protection scope of the present application. The "comprising" mentioned in the whole specification and claims is an open term, and should be interpreted as "comprising but not limited to". "Approximately" means that a person of ordinary skill in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0042] The roof system includes roof purlin and roof panel, etc. The roof panel is connected to the roof purlin by the connecting assembly to form the entire roof system. Usually, the roof panel is a color steel plate with a wave crest structure and a wave trough structure. When it rains, rainwater is collected in the wave trough structure, and then flows into the gutter of the roof system along the inclined direction of the roof panel, and finally is discharged through the pipeline.

[0043] With more and more functions of steel structure buildings, some other structural members are usually arranged on the roof system. In order to ensure that these structural members can be stably connected to the roof system, these structural members are usually stably connected to the roof purlin. Therefore, these structural members must penetrate the roof panel and extend above the roof panel. Obviously, when the structural member penetrates the roof panel, the integrity of the roof panel is damaged, which brings a severe challenge to the waterproof construction of the roof panel. Usually, flexible waterproof materials and sealant are used to close the penetration node where the structural member penetrates the roof panel. However, because the service life of these sealing materials is short, after the material fails, rainwater can easily penetrate into the building through the gap at the penetration node, thereby causing roof leakage.

[0044] In order to solve the above technical problems, see Figures 1 to 3In an embodiment of the present application, a roof waterproofing node system is provided, which comprises a roof body 1, a roof panel 2, a roof structural member 3, a water guide plate 4 and a first flashing 5. The roof panel 2 is connected to the roof body 1 in an inclined manner, and the roof body 1 comprises roof purlins 13, and the roof panel 2 is connected to the roof purlins 13. In addition, the roof body 1 can further comprise a thermal insulation cotton layer, which is arranged between the roof panel 2 and the roof purlins 13. The roof structural member 3 is connected to the roof body 1 at one end and extends to above the roof panel 2 through the roof panel 2 at the other end. In general, in order to facilitate the installation of the roof structural member 3 to the roof body 1, a mounting hole is formed in the roof panel 2, and the roof structural member 3 above the roof panel 2 is connected to the roof purlin 13 through the mounting hole.

[0045] Referring to Figure 1 and Figure 2 , along the inclined direction of the roof panel 2, one side of the through node 14 of the roof structural member 3 is an upstream area 21 of the roof panel 2, and the other side is a downstream area 22 of the roof panel 2; taking the through node 14 of the roof structural member 3 as a midpoint, the left side of the through node 14 is the upstream area 21 of the roof panel 2, and the right side of the through node 14 encloses the downstream area 22 of the roof panel 2. Rainwater flows from the upstream area 21 to the downstream area 22 along the inclined direction of the roof panel 2, and finally flows into the gutter assembly 12 at the end of the downstream area 22.

[0046] The water guide plate 4 is arranged on the roof panel 2 corresponding to the upstream area 21, and the first flashing 5 is arranged on the roof panel 2 corresponding to the downstream area 22; wherein one end of the water guide plate 4 has an upward structure 41 connected to the upstream side of the roof structural member 3; the first flashing 5 has a folded edge 51 connected to the downstream side of the roof structural member 3. Since the water guide plate 4 and the first flashing 5 are arranged above the roof panel 2 respectively, and part of the water guide plate 4 and the first flashing 5 is further connected to the roof structural member 3, the water guide plate 4 and the first flashing 5 can effectively shield rainwater at the through node 14 of the roof structural member 3, so as to avoid rainwater falling on the roof panel 2 around the through node 14, and further effectively avoid rainwater from leaking into the roof body 1 through the gap around the through node 14.

[0047] Referring to Figure 1 and Figure 2 In the technical solution provided in the present application, the water guide plate 4 and the first flashing 5 are arranged on the roof panel 2 at the through node 14 of the roof structural member 3, so as to shield the through node 14 and achieve good waterproofing effect. In addition, since the service life of the water guide plate 4 and the first flashing 5 is long, there is no aging phenomenon after long-term use like the waterproof structure and the sealant, so the arrangement of the water guide plate 4 and the first flashing 5 can effectively improve the quality and aesthetics of the roof system.

[0048] Referring to Figure 1 and Figure 2 In an embodiment, the water guide plate 4 is arranged on the upper side of the roof panel 2, and the other end of the water guide plate 4 extends to the end of the upstream area 21 of the roof panel 2. The inclination angle of the water guide plate 4 is the same as that of the roof panel 2. It is possible that the water guide plate 4 covers the roof panel 2 from above and covers the entire upstream area 21 of the roof panel 2. When it rains, the rainwater will directly fall on the water guide plate 4 and flow downward along the water guide plate 4, which can effectively prevent the rainwater from flowing into the upstream area 21 of the covered roof panel 2, and thus can prevent the rainwater from flowing along the upstream area 21 of the roof panel 2 to the through joint 14.

[0049] Referring to Figure 1 In an embodiment, the roof waterproof joint system further comprises a wall 15, and the end of the upstream area 21 of the roof panel 2 extends to the corner of the wall 15. The wall 15 includes but is not limited to a building facade wall, a parapet wall, etc. Hereinafter, the wall 15 is taken as a parapet wall for detailed description. The parapet wall is erected on the roof main body 1, and the end of the upstream area 21 of the roof panel is located at the corner of the parapet wall.

[0050] In order to prevent the rainwater on the parapet wall from flowing into the upstream area 21 of the roof panel 2 or flowing to the building main body below the roof panel 2, in an embodiment, the roof waterproof joint system further comprises a second flashing 7, one end of the second flashing 7 is connected to the wall 15, and the other end of the second flashing 7 is connected to the water guide plate 4 on the roof panel 2. Specifically, the first end of the second flashing 7 is connected to the wall surface, and the second end of the second flashing 7 is connected to the water guide plate 4 above the roof panel 2 after being bent. The second flashing 7 can effectively block the gap between the end of the roof panel 2 and the corner of the wall.

[0051] In an embodiment, the wall 15 is provided with an inner wall panel, the folded edge 51 of the second flashing 7 is connected to the inner side of the inner wall panel, and the other end of the second flashing 7 abuts above the water guide plate 4. Specifically, the first end of the second flashing 7 is connected to the inner side of the inner wall panel of the wall 15, and the second end of the second flashing 7 is connected to the water guide plate 4 above the roof panel 2 after being bent. The rainwater on the wall surface of the parapet wall can flow downward to the second flashing 7 and then flow to the water guide plate 4 through the second flashing 7. Therefore, when it rains, neither the falling rainwater nor the rainwater flowing down the wall surface will overflow to the roof panel 2 covered by the water guide plate 4 and the building main body below the roof panel 2, thereby effectively preventing the rainwater from leaking from the through joint 14.

[0052] The roof panel 2 is in an inclined state as mentioned above. The inclined state can be achieved by arranging the roof panel 2 on the inclined roof body 1 or by supporting and connecting the roof panel 2 on the horizontal roof body 1 through support frames of different heights.

[0053] Referring to Figure 1 In an embodiment provided by the present application, the waterproof joint system of the roof further comprises a first support 61 and a second support 62. One end of the first support 61 is connected to the upstream region 21 of the roof panel 2, and the other end of the first support 61 is connected to the roof body 1. One end of the second support 62 is connected to the downstream region 22 of the roof panel 2, and the other end of the second support 62 is connected to the roof body 1. The supporting height of the first support 61 is greater than that of the second support 62. Specifically, one end of the roof panel 2 is connected to the building body through the first support 61 with a relatively high height, and the other end of the roof panel 2 is connected to the roof body 1 through the second support 62 with a relatively low height, so that the roof panel 2 is arranged in an inclined state.

[0054] Referring to Figures 1 to 3 In an embodiment provided by the present application, the waterproof joint system of the roof further comprises a first plug 8 and a first fastener 81. The roof panel 2 has a wave crest structure 23 and a wave trough structure 24, and the first plug 8 is arranged in the wave trough structure 24 of the upstream region 21 of the roof panel 2. The first plug 8 is close to the end of the upstream region 21 of the roof panel 2, and the top end of the first plug 8 is flush with the top of the wave crest structure 23. The first fastener 81 penetrates the roof panel 2 and connects the first plug 8 to the first support 61 below the roof panel 2. In addition, a waterproof pad 16 is arranged between the bottom of the first plug 8 and the roof panel 2, and the first fastener 81 penetrates the bottom of the first plug 8, the roof panel 2 and the waterproof pad 16 and is connected to the roof body 1.

[0055] The waterproof pad 16 includes but is not limited to a butyl tape, a rubber pad, a waterproof coating and the like.

[0056] In addition, in order to further improve the waterproof performance of the connection of the first fastener 81, an upward waterproof member 82 is arranged between the first plug 8 and the roof panel 2. The upward waterproof member 82 is arranged at the bottom of the first plug 8, and the first fastener 81 penetrates the upward waterproof member 82 when penetrating the roof panel 2, so that the upward waterproof member 82 is tightly connected between the roof panel 2 and the first plug 8.

[0057] Further, the first plug member 8 has a first connecting portion 83 on one side, and a connecting member penetrates the water guide plate 4 and is connected to the first connecting portion 83. Specifically, the connecting member not only penetrates the water guide plate 4 and is connected to the first connecting portion 83, but also penetrates the second flashing member 7 and the roof panel 2 at the same time. The connecting member can connect the second flashing member 7, the water guide plate 4, the roof panel 2 and the first plug member 8 to each other, so that the roof waterproof node system is more firm. In order to avoid the risk of water leakage when the connecting member penetrates the first flashing member 5 and the roof panel 2, a waterproof pad 16 is arranged between the second flashing member 7 and the water guide plate 4 and between the water guide plate 4 and the roof panel 2, respectively. Therefore, when the connecting member penetrates the second flashing member 7, the water guide plate 4 and the roof panel 2, the waterproof pad 16 can effectively fill the gap and avoid water leakage. The connecting member includes but is not limited to self-tapping nails, fastening bolts and the like.

[0058] Referring to Figures 1 to 3 In an embodiment provided by the present application, the roof waterproof node system further comprises a second plug member 9 and a second fastener 91. The second plug member 9 is arranged in the valley structure 24 of the downstream area 22 of the roof panel 2, and the second fastener 91 penetrates the roof panel 2 to connect the second plug member 9 to the roof panel 2. Similarly, in order to avoid water leakage of the roof panel 2 when the second fastener 91 penetrates the roof panel 2, a waterproof pad 16 is arranged between the bottom of the second plug member 9 and the roof panel 2.

[0059] In addition, the first plug member 8 and the second plug member 9 have similar structures. The second plug member 9 has a second connecting portion 92 on one side, and a fastener penetrates the first flashing member 5 and the roof panel 2 and is connected to the second connecting portion 92. A waterproof pad 16 is also arranged between the first flashing member 5 and the roof panel 2.

[0060] In order to improve the sealing performance of the roof panel 2, referring to Figure 1 In an embodiment provided by the present application, the roof waterproof node system further comprises a third plug member 10 and a third fastener 11. The third plug member 10 is arranged in the peak structure 23 of the downstream area 22 of the roof panel 2, and the third fastener 11 penetrates the roof panel 2 to connect the third plug member 10 to the second support member 62 below the roof panel 2. Specifically, the third plug member 10 has a structure shape matched with the peak structure 23 of the roof panel 2, and the third plug member 10 is located below the peak structure 23 and can be connected to the roof panel 2 by sealing glue.

[0061] Referring to Figure 1 In an embodiment provided by the present application, the roof waterproof node system further comprises a gutter assembly 12 arranged on one side of the end of the downstream area 22 of the roof panel 2, and the gutter assembly 12 is connected to the roof body 1. In the inclined direction of the roof panel 2, the rainwater on the roof panel 2 can flow into the gutter assembly 12, and a drain pipe is connected to the gutter assembly 12. The rainwater in the gutter assembly 12 is discharged through the drain pipe.

[0062] See Figure 1 and Figure 3 In one embodiment provided in this application, the water guide plate 4 is further provided with downward-folding structures 42 on both sides, which extend into the trough structure 24 of the roof panel 2. This allows rainwater on the water guide plate 4 to flow into the trough structure 24 of the upstream region 21 of the roof panel 2, while the through node 14 of the roof structural member 3 is located in the trough structure 24 of the upstream region 21 covered by the water guide plate 4. Rainwater from the water guide plate 4 can flow to the downstream region 22 of the roof panel 2 through other trough structures 24 on both sides of the trough structure 24, and ultimately flow into the gutter assembly 12.

[0063] In summary, the technical solution provided in this application achieves excellent waterproofing by installing a water guide plate and a first flashing on the roof panel at the through-node of the roof structural components, thereby shielding the through-node. Furthermore, because the water guide plate and the first flashing have a long service life and do not exhibit the aging phenomenon seen in waterproof structures and sealants after prolonged use, their installation effectively improves the quality and aesthetics of the roof system.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
