[0048] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0049] like Figure 1 and Figure 2 As shown, the roofing system in the prior art includes, from top to bottom, an outer corrugated sheet 106, a bracket 105, a bracket isolation pad 114, a waterproof roll 201, a thermal insulation layer 104, a purlin 102, a vapor barrier membrane 202, a common support 203, and a corrugated steel sheet 204. It can be seen that the waterproof layer of the roofing system in the prior art is usually a waterproof roll 201 arranged above the thermal insulation layer 104. The waterproof roll 201 is arranged above the thermal insulation layer 104. In summer, the waterproof roll 201 may be plasticized in a high temperature environment, the strength is reduced, and micro cracks are prone to occur; while in winter, in a low temperature environment, the waterproof roll 201 is prone to elastic deformation, which is not conducive to improving the service life of the waterproof roll 201 and ensuring the waterproof performance of the waterproof roll 201.

[0050] In view of this, if Figures 5 to 9As shown, the utility model provides a roofing system, which includes an inner layer profiled board 101a, a profiled board waterproof layer 101b, a lining purlin 102, a thermal insulation layer 104, and an outer layer profiled board 106. The profiled board waterproof layer 101b is arranged on the upper surface of the inner layer profiled board 101a, the lining purlin 102 is arranged above the profiled board waterproof layer 101b through a support 103, the thermal insulation layer 104 is arranged above the lining purlin 102, and the outer layer profiled board 106 is arranged above the thermal insulation layer 104 through a bracket 105. It can be seen that the outer layer profiled board 106, the thermal insulation layer 104, the lining purlin 102, the profiled board waterproof layer 101b, and the inner layer profiled board 101a are arranged in sequence from top to bottom, and the profiled board waterproof layer 101b is located below the thermal insulation layer 104. Since the thermal insulation layer 104 has the effect of thermal insulation, the corrugated board waterproof layer 101b can be placed in a relatively suitable temperature environment regardless of summer or winter, thereby delaying the plasticization or elastic deformation of the corrugated board waterproof layer 101b, which is beneficial to extending the service life of the corrugated board waterproof layer 101b and ensuring the waterproof performance of the corrugated board waterproof layer 101b.

[0051] In some specific embodiments, Figure 3 As shown, in order to reduce the construction structure layers of the roof and speed up the construction speed, the inner layer profiled board 101a and the profiled board waterproof layer 101b can be integrally formed into a composite profiled board 101, and the profiled board waterproof layer 101b is a TPO waterproof layer compositely formed on the inner layer profiled board 101a. Specifically, the composite profiled board 101 can be a plastic steel tile that replaces the original corrugated steel plate bearing layer, and the plastic steel tile is a material composited with a metal plate and a TPO coil.

[0052] In addition, in the prior art, due to construction requirements, the bracket fixing screws inevitably penetrate the waterproofing coil 201, and the site is basically not waterproofed at the point where the screws penetrate the waterproofing coil, and the leakage of the bracket fixing screws will seep downward to the corrugated steel plate 204 and the space below it, resulting in poor waterproof performance of the roof system. In addition, due to the large number of brackets 105, it is difficult to be foolproof when applying sealant to the bracket fixing screws, and the potential risk of roof leakage is high.

[0053] In the roofing system of the present application, the corrugated board waterproof layer 101b is arranged between the lining purlin 102 and the inner corrugated board 101a. Even if the bracket fixing screws leak, due to the waterproof effect of the corrugated board waterproof layer 101b, the leaked water will not seep downward to the inner corrugated board and the space below it.

[0054] Furthermore, if Figure 4As shown, the support member 103 may be a composite plate and include a support member metal substrate 103e and a support member lower waterproof layer 103a, the support member lower waterproof layer 103a is compositely formed on the lower surface of the support member metal substrate 103e, and the corrugated board waterproof layer 101b is compatible with the support member lower waterproof layer 103a. Figure 5 , Figure 7 , Figure 8 as well as Fig.10 As shown, the waterproof layer 101b of the corrugated board is hot-air welded with the lower waterproof layer 103a of the support member, so that the support member 103 can be fixed on the composite corrugated board 101. In addition, when the support member 103 is also fixed on the composite corrugated board 101 through the lower fastener 107, the waterproof layer 101b of the corrugated board is hot-air welded with the lower waterproof layer 103a of the support member, so that a sealed waterproof structure can be formed around the perforated position of the lower fastener 107, so as to prevent water from directly penetrating into the perforated position of the lower fastener 107 from the gap between the connecting wing plate parts 103c on both sides of the support member 103 and the composite corrugated board 101.

[0055] Compatibility means that two adjacent layers of material can melt and bond when heated above a specific temperature and can return to a solid state and maintain stable bonding when the temperature is below the specific temperature. Melt bonding can be that both layers are in a molten state, or one layer remains solid while the other is in a molten state (in this case, the two layers have different melting points).

[0056] Furthermore, if Figure 4 As shown, the upper surface of the support metal substrate 103e of the support 103 is also compounded with a support upper waterproof layer 103b. Figure 7 and Fig.10 As shown, the support member 103 is connected to the inner laminated plate 101a through the lower fastener 107, the lower fastener 107 is covered with a first waterproof patch 108, the waterproof layer 103b on the support member and the first waterproof patch 108 are compatible, and the first waterproof patch 108 is hot-air welded to the waterproof layer 103b on the support member. In this way, the first waterproof patch 108 can seal and waterproof the perforated position between the support member 103 and the lower fastener 107 to prevent water from leaking downward through the perforated position between the support member 103 and the lower fastener 107.

[0057] In addition, if Figure 3 and Figure 4 As shown, the inner laminated plate 101a may include a convex rib portion 101a1 protruding upward, and the support member 103 may include connecting wing plate portions 103c at both ends and a middle protruding portion 103d connected between the connecting wing plate portions 103c at both ends and protruding upward. Figure 7 and Fig.10As shown, the middle raised portion 103d is spaced apart on the convex rib portion 101a1 and connected to the purlin 102, and the wing plate portion 103c is connected to the corrugated board waterproof layer 101b by hot air welding.

[0058] Optionally, in order to further improve the sealing and waterproofing effect of the roofing system, Fig.10 As shown, the first waterproof patch 108 extends in a direction away from the middle raised portion 103d and is hot-air welded to the corrugated board waterproof layer 101b.

[0059] In the prior art, such as Figure 1 As shown, since the fastener passes through the lining purlin 102, the vapor barrier membrane 202, the ordinary support member 203 and the corrugated steel plate 204 in sequence, there is a greater risk of water leakage at the perforation position of the fastener.

[0060] In order to further improve the waterproof performance of the roofing system of the utility model, in some embodiments, such as Figure 7 and Fig.10 As shown, the middle raised portion 103d can be connected to the purlin 102 through the upper fastener 109, and the upper fastener 109 is arranged above the convex rib portion 101a1 at intervals, that is, the composite corrugated board 101 is not penetrated by the upper fastener 109, which can effectively avoid the hidden danger of water leakage.

[0061] Optionally, the upper waterproof layer 103b of the support member and the lower waterproof layer 103a of the support member are weldable polymer coatings or TPO films.

[0062] In some embodiments, Figure 8 and Fig.11 As shown, the roofing system may further include a purlin 110, which is arranged below the inner layer corrugated board 101a and connected to the composite corrugated board 101 through a purlin fastener 111, and a second waterproof patch 112 is provided on the purlin fastener 111, and the second waterproof patch 112 is compatible with the corrugated board waterproof layer 101b. The second waterproof patch 112 is hot-air welded to the corrugated board waterproof layer 101b, thereby solving the water leakage problem at the purlin fastener 111.

[0063] In addition, if Figure 5 , Figure 6 , Figure 8 as well as Fig. 9 As shown, the roof system may further include a waterproof vapor-permeable membrane 113, which is disposed between the thermal insulation layer 104 and the outer laminated board 106. The waterproof vapor-permeable membrane 113 can prevent rainwater from entering the thermal insulation layer 104, and can also discharge some water vapor generated in the thermal insulation layer 104 to the outside, so that the thermal insulation layer 104 can remain dry for a long time.

[0064] In summary, the roofing system of the utility model is provided with a corrugated board waterproof layer between the lining purlin and the inner corrugated board, and the inner corrugated board and the corrugated board waterproof layer are integrated into a composite corrugated board, which reduces the construction structure layers of the roof and speeds up the construction speed. The corrugated board waterproof layer is located below the thermal insulation layer, which is beneficial to prolonging the service life of the corrugated board waterproof layer and ensuring the waterproof performance of the corrugated board waterproof layer, and can effectively prevent the leakage of the bracket fixing screws from seeping downward to the inner corrugated board and the space below it, eliminating the hidden danger of water leakage in the roofing system, and having good waterproof performance. The double-sided composite TPO of the support member can be hot-air welded with the corrugated board waterproof layer and the waterproof patch to form a waterproof structure, which can prevent water from penetrating into the perforated position of the fastener, effectively solving the water leakage problem of the fastener. In addition, a layer of waterproof and breathable membrane is provided above the thermal insulation layer, which further improves the waterproof performance and breathable performance of the roofing system.
