[0002] In the existing roofing system, to simplify the construction process, prefabricated plates formed by laminating a waterproof coiled material, a thermal insulation layer, and a metal plate together are generally used for roofing. In the existing prefabricated plates, most of the thermal insulation layers are composed of deformable materials, and the waterproof coiled material is only bonded to the thermal insulation layer by adhesive, and its anti-peeling ability is low. Under the influence of wind, it is easy to peel off the thermal insulation layer, thus causing roof leakage. Summary of the Utility Model

[0003] In view of the above-mentioned at least one defect or deficiency of the prior art, this application provides a roofing system and a roofing composite panel, which can improve the overall wind resistance of the roofing system and enhance the connection strength between multiple roofing composite panels.

[0004] To achieve the above object, on the one hand, this application provides a roofing system, including a first through-connection component, a second through-connection component, and a plurality of roofing composite panels for splicing and laying on the roof. The roofing composite panel includes a waterproof coiled material, a thermal insulation layer, and a metal plate that are stacked in sequence from top to bottom. The transverse ends of the roofing composite panel are respectively formed into a splicing male edge portion and a splicing female edge portion. The portion of the metal plate located at the splicing female edge portion is formed into a female edge overlapping portion extending out of the edge of the thermal insulation layer. The splicing male edge portion of one of the two mutually spliced roofing composite panels overlaps on the female edge overlapping portion of the other. The first through-connection component is used to penetrate and connect the female edge overlapping portion and the roof purlin, and the second through-connection component is used to sequentially penetrate and connect the splicing male edge portion and the female edge overlapping portion.

[0005] In some embodiments, the female edge overlapping portion is formed into a female edge groove portion, and the splicing male edge portion is formed into a male edge protruding portion embedded in the female edge groove portion; and / or, the portion of the metal plate located at the splicing male edge portion extends out to form an upwardly warped portion, and the upwardly warped portion abuts against the side wall of the thermal insulation layer.

[0006] In some embodiments, the roofing system includes a splicing seam defined by the bottom wall of the male edge protruding portion embedded in the female edge groove portion and the top wall of the female edge groove portion. The first through-connection component includes a first screw. When the first screw penetrates and connects the female edge groove portion and the roof purlin, the screw head of the first screw is located in the splicing seam.

[0007] In some embodiments, the thermal insulation layer includes a first thermal insulation material layer and a second thermal insulation material layer that circumferentially wraps the first thermal insulation material layer. At least the second thermal insulation material layer is provided in the portions of the thermal insulation layer located at the splicing male edge portion and the splicing female edge portion.

[0008] In some embodiments, the second connecting component includes a second screw and a screw gasket. The second screw is used to sequentially connect the screw gasket, the splicing male edge portion, the female edge overlapping portion, and the roof purlin.

[0009] In some embodiments, the portion of the waterproof coiled material located at the splicing female edge portion is formed as a coiled material overlapping portion that extends beyond the edge of the thermal insulation layer. Among the two mutually spliced roof composite panels, the coiled material overlapping portion of one of the roof composite panels covers the top of the second connecting component and is welded to the top surface of the waterproof coiled material of the other roof composite panel.

[0010] The second aspect of the present application provides a roof composite panel, which includes a waterproof coiled material, a thermal insulation layer, and a metal plate that are sequentially stacked up and down. The transverse ends of the roof composite panel are respectively formed as a splicing male edge portion and a splicing female edge portion. The portion of the metal plate located at the splicing female edge portion is formed as a female edge overlapping portion that extends beyond the edge of the thermal insulation layer. The thermal insulation layer includes a first thermal insulation material layer and a second thermal insulation material layer that circumferentially wraps the first thermal insulation material layer. At least the second thermal insulation material layer is provided in the portions of the thermal insulation layer located at the splicing male edge portion and the splicing female edge portion.

[0011] In some embodiments, the female edge overlapping portion is formed as a female edge groove portion, and the splicing male edge portion is formed as a male edge protruding portion; and / or, the portion of the metal plate located at the splicing male edge portion extends out to form an upturned portion, and the upturned portion abuts against the side wall of the second thermal insulation material layer.

[0014] Through the above technical solution, for two mutually spliced roof composite panels, by overlapping the splicing male edge part of one of them on the female edge overlapping part of the other, and using the first through-connection component to connect the female edge overlapping part and the roof purlin, and using the second through-connection component to sequentially connect the splicing male edge part and the female edge overlapping part, the two mutually spliced roof composite panels can be firmly locked together. For the roof system spliced by multiple roof composite panels, the overall structural strength and structural stability are greatly improved. In addition, when the second through-connection component connects the splicing male edge part, the waterproof coiled material located at the top layer of the splicing male edge part can be closely attached to the thermal insulation layer, thereby effectively improving the anti-peeling ability of the waterproof coiled material, enhancing the wind resistance of the roof composite panel and even the entire roof system, and preventing the roof from being damaged by wind.

[0030] The following will describe in detail the detailed implementation manners of the present application with reference to the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustration and explanation of the present application, and are not used to limit the present application.

[0031] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0032] As Figures 1 to 3 shown, the first exemplary embodiment of the present application provides a roofing system, which includes a first through-connection assembly 1, a second through-connection assembly 2, and a plurality of roofing composite panels 3 for splicing and laying on the roof. Among them, the roofing composite panel 3 includes a waterproof coil 301, a thermal insulation layer 302, and a metal plate 303 that are stacked in sequence from top to bottom. The transverse ends of the roofing composite panel 3 are respectively formed into a male splicing edge part 304 and a female splicing edge part 305. The part of the metal plate 303 located in the female splicing edge part 305 is formed into a female edge overlapping part 3031 that extends out of the edge of the thermal insulation layer 302. The male splicing edge part 304 of one of the two mutually spliced roofing composite panels 3 overlaps on the female edge overlapping part 3031 of the other. The first through-connection assembly 1 is used to pass through and connect the female edge overlapping part 3031 and the roof purlin 5, so as to lock the female splicing edge part 305 of the roofing composite panel 3 on the roof purlin 5. The second through-connection assembly 2 is used to sequentially pass through and connect the male splicing edge part 304 and the female edge overlapping part 3031, so as to lock the two roofing composite panels 3 to each other on the roof purlin 5. When the second through-connection assembly 2 passes through and connects the male splicing edge part 304, it can sequentially pass through the waterproof coil 301, the thermal insulation layer 302, and the metal plate 303 located in the male splicing edge part 304, so as to lock the waterproof coil 301 on the thermal insulation layer 302.

[0033] It can be seen that in the roof system of the present exemplary embodiment, for two mutually spliced roof composite panels 3, by overlapping the splicing male edge portion 304 of one of them on the female edge overlapping portion 305 of the other, and using the first through-connecting component 1 to pass through and connect the female edge overlapping portion 3031 and the roof purlin 5, and using the second through-connecting component 2 to sequentially pass through and connect the splicing male edge portion 304 and the female edge overlapping portion 305, the two mutually spliced roof composite panels 3 can be firmly locked together. In this way, for the roof system spliced by multiple roof composite panels 3, the overall structural strength and structural stability of the roof system can be greatly improved. In addition, in the state where the second through-connecting component 2 passes through and connects the splicing male edge portion 304, the waterproof coiled material 301 located at the top layer of the splicing male edge portion 304 can be pressed against the thermal insulation layer 302, thereby effectively improving the anti-peeling ability of the waterproof coiled material 301, and enhancing the wind resistance of the roof composite panel 3 and even the entire roof system, effectively avoiding damage to the roof due to the influence of wind force.

[0034] In an alternative or preferred embodiment, as Figure 2 and Figure 3 shown, the female edge overlapping portion 3031 is formed as a female edge groove portion, and the splicing male edge portion 304 is formed as a male edge protruding portion. In two mutually spliced roof composite panels 3, the male edge protruding portion is embedded in the female edge groove portion, so that the two roof composite panels 3 can be mutually limited, effectively avoiding the offset of the unfixed roof composite panel 3 in the case where the second through-connecting component 2 is not passed through and connected.

[0035] Furthermore, referring to Figure 4 , the part of the metal plate 303 located at the splicing male edge portion 304 can extend out to form an upturned portion 3032, and the upturned portion 3032 abuts against the side wall of the thermal insulation layer 302, so that a rigid edge wrapping formed by the metal plate 303 is formed at the bottom of the splicing male edge portion 304. Under the partial wrapping of the metal plate 303, the thermal insulation layer 302 can be effectively protected to a certain extent, and the structural strength of the roof composite panel 3 is effectively enhanced.

[0036] In an alternative or preferred embodiment, as Figure 2 shown, the roof system includes a splicing seam 4, and the splicing seam 4 is defined by the bottom wall of the male edge protruding portion embedded in the female edge groove portion and the top wall of the female edge groove portion. The first through-connecting component 1 includes a first screw. In the case where the first screw passes through and connects the female edge groove portion and the roof purlin 5, the screw head of the first screw is located in the splicing seam 4. In Figure 2 the shown embodiment, the cross-sections of the male edge protruding portion and the female edge groove portion are both conical. Among them, the outward expansion angle of the male edge protruding portion is greater than the outward expansion angle of the female edge groove portion, so that when the male edge protruding portion is embedded in the female edge groove portion, the bottom wall of the male edge protruding portion is spaced from the top wall of the female edge groove portion, avoiding damage caused by the bottom wall of the male edge protruding portion pressing on the screw head of the first screw.

[0037] In an alternative or preferred embodiment, as Figure 4 shown, the thermal insulation layer 302 includes a first thermal insulation material layer 3021 and a second thermal insulation material layer 3022 that circumferentially wraps the first thermal insulation material layer 3021. At least the second thermal insulation material layer 3022 is provided in the portions of the thermal insulation layer 302 located at the splicing male edge portion 304 and the splicing female edge portion 305. In this way, by using the second thermal insulation material layer 3022 to seal the edge of the first thermal insulation material layer 3021, on the one hand, the overall structural strength of the entire roof composite panel 3 can be enhanced. For example, using a relatively rigid material as the second thermal insulation material layer 3022 is beneficial to reducing the risk of damage during transportation and construction. On the other hand, the second thermal insulation material layer 3022 can prevent rainwater or water vapor in the air from entering the first thermal insulation material layer 3021, so as not to reduce the thermal insulation effect.

[0038] It should be noted that in this embodiment, fiber materials such as rock wool and glass wool can be used as the first thermal insulation material layer 3021, which has an ideal thermal insulation effect and low cost. At the same time, foaming materials such as polyurethane can be used as the second thermal insulation material layer 3022, which has low preparation difficulty and good sealing effect, and is suitable for the integrated production of the thermal insulation layer 302.

[0039] In an alternative or preferred embodiment, referring to Figure 3 , the second connecting component 2 includes a second screw and a screw gasket. The second screw is used to sequentially connect the screw gasket, the splicing male edge portion 304, and the female edge overlapping portion 3031. In this embodiment, a C-shaped gasket can be used as the screw gasket. By using the second screw in cooperation with the C-shaped gasket, the portion of the waterproof coiled material 301 located at the splicing male edge portion 304 can be effectively pressed against the thermal insulation layer 302, so that it firmly adheres to the thermal insulation layer 302. In this way, the peeling of the waterproof coiled material 301 caused by the influence of wind can be avoided, and the wind resistance of the roof composite panel 3 is greatly enhanced. It should be noted that the connecting positions of the second connecting component 2 and the first connecting component 1 are staggered from each other to avoid damaging each other's connecting holes.

[0040] In other embodiments, after using the second connecting component 2 to connect the splicing male edge portion 304 and the female edge overlapping portion 3031, the roof purlin 5 can be continuously connected, so that the second connecting component 2 simultaneously connects and fixes two roof composite panels 3 and the roof purlin 5, thereby further enhancing the stability of the two mutually spliced roof composite panels 3.

[0041] Further, referring to Figures 1 to 3, the part of the waterproof coiled material 301 located at the splicing mother edge part 305 is formed into a coiled material lapping part 3011 extending out of the edge of the thermal insulation layer 302. Among the two roof composite panels 3 spliced with each other, the coiled material lapping part 3011 of one roof composite panel 3 covers the top of the second through-connecting component 2 and is welded to the top surface of the waterproof coiled material 301 of the other roof composite panel 3, so that the coiled material lapping part 3011 can seal the joint seam of the two roof composite panels 3. In particular, it can completely seal the wound formed after the second through-connecting component 2 passes through and splices the splicing male edge part 304. In this way, the overall sealing performance of the roof system can be guaranteed, making it achieve excellent waterproof and heat insulation effects.

[0042] The second exemplary embodiment of the present application provides a roof composite panel that can be used to splice the above-mentioned roof system. Therefore, the technical effects brought by the corresponding embodiments of the above-mentioned roof system can obviously also be obtained for the various embodiments of the roof composite panel described below. Therefore, for the various embodiments described below, only the additional technical effects brought by their structural features are described to avoid repeating the previous content.

[0043] Specifically, as Figure 4 shown, the roof composite panel 3 includes a waterproof coiled material 301, a thermal insulation layer 302, and a metal plate 303 that are sequentially stacked up and down. The transverse two ends of the roof composite panel 3 are respectively formed into a splicing male edge part 304 and a splicing mother edge part 305. The part of the metal plate 303 located at the splicing mother edge part 305 is formed into a mother edge lapping part 3031 extending out of the edge of the thermal insulation layer 302. The thermal insulation layer 302 includes a first thermal insulation material layer 3021 and a second thermal insulation material layer 3022 that wraps the first thermal insulation material layer 3021 along the circumference. The parts of the thermal insulation layer 302 located at the splicing male edge part 304 and the splicing mother edge part 305 are at least provided with the second thermal insulation material layer 3022. In other words, the second thermal insulation material layer 3022 is used to seal the edge of the first thermal insulation material layer 3021. During the construction of the roof system, when the second through-connecting component 2 passes through and connects the splicing male edge part 304 and the mother edge lapping part 3031 in sequence, the second through-connecting component 2 can pass through the second thermal insulation material layer 3022 in the splicing male edge part 304. Since a relatively hard material such as polyurethane can be used as the second thermal insulation material layer 3022, the second thermal insulation material layer 3022 can provide sufficient fixing support force and enhance the connection strength.

[0044] In Figure 4 the shown embodiment, the mother edge lapping part 3031 is formed into a mother edge groove part, and the splicing male edge part 304 is formed into a male edge protruding part. When it is necessary to lap one roof composite panel 3 on another roof composite panel 3, the protruding part of the male edge protruding part of one roof composite panel 3 can be inserted into the mother edge groove part.

[0045] Furthermore, a part of the metal plate 303 located at the splicing common edge portion 304 extends out to form an upturned portion 3032, and the upturned portion 3032 abuts against the side wall of the second heat insulation material layer 3022, thereby locally wrapping the bottom of the second heat insulation material layer 3022 to enhance the structural strength.

[0046] In an alternative or preferred embodiment, the first heat insulation material layer 3021 is made of a fiber material, such as rock wool material or fiberglass wool material, and the second heat insulation material layer 3022 is made of a polyurethane material.

[0047] In an alternative or preferred embodiment, the waterproof coiled material 301 includes a first waterproof material layer, a fiber reinforcement layer, a second waterproof material layer, and a non-woven fiber layer that are stacked in sequence from top to bottom. Among them, TPO material or PVC material can be selected as the first waterproof material layer and the second waterproof material layer. At the same time, one or more of polyester fiber, nylon fiber, and carbon fiber can be selected as the fiber reinforcement layer, so as to improve the tensile and tear resistance of the waterproof coiled material 301. In addition, polyester non-woven fabric or the like can be selected as the non-woven fiber layer, so as to enhance the bonding strength between the waterproof coiled material 301 and the heat insulation layer 302.

[0048] In the integrated manufacturing process of the roof composite panel 3, the waterproof coiled material 301 can be bonded to the heat insulation layer 302 through an adhesive. Similarly, the heat insulation layer 302 can also be bonded to the metal plate 303 through an adhesive. The waterproof coiled material 301 in this embodiment is a special composite waterproof coiled material, which has high tensile and tear strength, and the non-woven fiber layer as the backing layer can have a better bonding effect with the heat insulation layer 302, thereby enhancing the anti-peeling ability of the waterproof coiled material 301 and making the product itself have better fitting strength and wind resistance.
