[0030] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0032] The applicant discovered during the process of researching and improving the existing metal roofing system that:

[0033] 1. The existing metal roof system uses mostly glass wool as insulation material. The glass wool is usually veneered on the side facing the room to play a role in vapor isolation. However, since there is no special sealing measure on the edge of the veneer, the roof system has poor vapor isolation performance. Indoor moisture can easily enter the glass wool insulation layer through the veneer gap, reducing its insulation performance and easily causing condensation in winter.

[0034] 2. Metal plates exposed to the outside are prone to rust and corrosion, resulting in a short service life of the metal roof system; metal plates are prone to deformation due to thermal expansion and contraction, and water leaks easily at the seams; metal plates are rigidly connected to other roof components or detailed nodes, which are prone to water leakage.

[0035] In order to solve the problems of the prior art, the embodiments of the present application provide a roof structure plate and a vapor-insulating, heat-insulating and waterproof roof system.

[0036] The following first introduces the roof structure board material provided in the embodiment of the present application. Figure 1 A structural diagram of a roofing structural board provided by an embodiment of the present application is shown.

[0037] like Figure 1 As shown, the roof structure board comprises a roof structure layer 7 , and the roof structure layer 7 comprises more than two roof structure units 70 . Two adjacent roof structure units 70 are flexibly and sealedly connected along a first direction D1 and / or a second direction D2 of the roof structure layer 7 .

[0038] The roof structure board material of the embodiment of the present application prevents water leakage between gaps caused by deformation of the roof structure units due to thermal expansion and contraction by flexibly and sealingly connecting adjacent roof structure units of the roof structure layer along the first direction and / or the second direction of the roof structure layer, thereby improving the waterproof performance of the roof structure board material.

[0039] In some optional embodiments, such as Figure 1 As shown, adjacent roof structure units 70 are flexibly sealed and connected along the second direction D2 of the roof structure layer 7, so as to flexibly seal and connect the roof structure units 70 in the short side direction.

[0040] In some embodiments, reference Figure 1 As shown, adjacent roof structure units 70 are flexibly sealed and connected along a first direction D1 of the roof structure layer 7 so as to flexibly seal and connect the roof structure units 70 in the long side direction.

[0041] In some optional embodiments, such as Figure 1 As shown, adjacent roof structure units 70 are flexibly sealed and connected along the first direction D1 and the second direction D2 of the roof structure layer, so that adjacent roof structure units 70 are arranged in a matrix distribution, flexibly sealed and connected in both the long and short side directions, and assembled to form a roof structure panel with waterproof performance.

[0042] In some embodiments, Figure 1 As shown, the connection between adjacent roof structure units 70 is provided with a roll material connector 8, which is arranged on the upper part of the connection between adjacent roof structure units 70, so that the connection between adjacent roof structure units 70 can be flexibly and sealedly connected by the roll material connector 8 adapting to the shape of the roof structure unit 70.

[0043] In some embodiments, the sides of adjacent roof structure units 70 connected to each other are connected to the coiled material connector 8, which is used to flexibly and sealably connect the adjacent roof structure units 70. It is understandable that the coiled material connector 8 can be arranged to cover the roof structure unit 70, protrude from the roof structure unit 70, and be arranged on the side of the roof structure unit 70 to be connected, and be integrally connected with the roof structure unit 70, so as to achieve a flexible and sealed connection with the coiled material connector 8 of the adjacent roof structure unit 70 by welding or hot melting.

[0044] The coiled material connector 8 can be made of a flexible and tough polymer waterproof coiled material, so as to adapt to the thermal expansion and contraction of the roof structure unit 70, and flexibly seal and connect the gap formed at the connection of adjacent roof structure units 70. For example, the polymer waterproof coiled material can be TPO waterproof coiled material, butyl sealant waterproof coiled material, polyethylene waterproof coiled material. Optionally, the polymer waterproof coiled material can be made of the same material as the roof structure unit 70, so that the coiled material connector 8 can be connected to the roof structure unit 70 by welding.

[0045] In some embodiments, Figure 1 As shown, the roof structure unit 70 includes a plurality of profiled portions 700 extending along the first direction D1 and spaced apart by connecting portions 701 in the second direction D2, and the profiled portions 700 are formed by protruding from the first surface toward the second surface of the roof structure layer 7. In the embodiment of the present application, the first surface refers to the side of the roof structure unit 70 connected to the thermal insulation layer 6, and the second surface is the side of the roof structure unit 70 away from the thermal insulation layer 6.

[0046] In some embodiments, Figure 1 As shown in FIG. 3 , the roof structure unit 70 is a plastic steel tile, which can adapt to the temperature of the external environment and is not easily deformed under the action of thermal expansion and contraction. The rigid connection of the detail nodes is changed into a flexible connection, which solves the problem of water leakage in the gaps caused by thermal expansion and contraction of the steel plate. And the flexible sealing connection of the coiled material connector 8 can effectively prevent the water vapor in the external environment from entering the steam-insulating and waterproof roofing system through the roof structure unit 70, thereby improving the waterproof ability of the steam-insulating and waterproof roofing system and extending the service life of the steam-insulating and waterproof roofing system.

[0047] In a second aspect, an embodiment of the present application provides a vapor-insulating, heat-insulating and waterproof roofing system. Figure 3 As shown, the vapor-proof, heat-insulating and waterproof roofing system includes: the above-mentioned roofing structure board; and a heat-insulating layer 6 located on the first surface of the roofing structure layer 7.

[0048] In the embodiment of the present application, the first surface of the roof structure layer 7, that is, the side where the roof structure layer 7 is connected to the thermal insulation layer 6. Figure 1 In the embodiment, the first surface, i.e., the lower surface of the roof structure layer 7, is used for sealing connection with the thermal insulation layer 6.

[0049] According to the vapor-insulating and waterproof roofing system of the embodiment of the present application, the adjacent roofing structural units of the roofing structural layer are flexibly sealed and connected along the first direction and / or the second direction of the roofing structural layer to prevent water leakage between gaps caused by deformation of the roofing structural units due to thermal expansion and contraction, thereby improving the waterproof performance of the vapor-insulating and waterproof roofing system. The thermal insulation layer also improves the thermal insulation performance of the vapor-insulating and waterproof roofing system.

[0050] In some embodiments, Figure 3 As shown, the vapor-proof, thermal-insulating and waterproof roofing system further comprises a vapor-proof layer 5, which is arranged on the side of the thermal-insulating layer 6 facing away from the roofing structure layer 7; wherein the vapor-proof layer 5 is sealed and connected to the overlapping part of the thermal-insulating layer 6.

[0051] The vapor-isolating, thermal-insulating and waterproof roofing system of the embodiment of the present application can prevent water vapor from entering the thermal-insulating layer 6 by arranging a vapor-isolating layer 5 on one side of the thermal-insulating layer 6 and sealing the overlapped portion of the thermal-insulating layer 6 and the vapor-isolating layer 5, thereby improving the vapor-isolating and thermal-insulating properties of the vapor-isolating, thermal-insulating and waterproof roofing system.

[0052] Exemplarily, the overlapped portion of the thermal insulation layer 6 and the vapor barrier layer 5 is located at the peripheral side where the vapor barrier layer 5 contacts the thermal insulation layer 6, or at all overlapped positions of the thermal insulation layer 6 and the vapor barrier layer 5. A sealing connection material can be used to seal the overlapped portion.

[0053] In some embodiments, the overlapping portion of the vapor barrier layer 5 and the thermal insulation layer 6 is sealed and connected using butyl sealing tape, wherein the butyl sealing tape is a double-sided self-adhesive sealing tape, which prevents water vapor from entering the thermal insulation layer 6, thereby improving the vapor insulation and thermal insulation performance of the vapor insulation and waterproof roofing system. It is understandable that in other embodiments of the present application, other materials that can seal the overlapping portion of the vapor barrier layer 5 and the thermal insulation layer 6 can also be used, such as double-sided self-adhesive epoxy sealing tape, acrylic sealing tape, polyurethane sealing tape, and polysulfide sealing tape. The sealing material can be obtained through commercial channels.

[0054] In some embodiments, the roof structure board is independently provided from the thermal insulation layer 6 and the vapor barrier layer 5 below it. Figure 3 As shown, the first direction D1 is used as the length direction of the roof structure board, and the second direction D2 is used as the width direction of the roof structure board. In other embodiments, the roof structure layer 7 can also use D2 as the length direction and D1 as the width direction.

[0055] In some embodiments, Figure 3As shown, the vapor-insulating and waterproof roofing system further includes a structural reinforcement 11 disposed on the side of the vapor-insulating layer 5 away from the thermal insulation layer 6. The structural reinforcement 11 enables the vapor-insulating layer 5 and the thermal insulation layer 6 to be firmly and stably disposed on the supporting structure, and improves the structural strength of the vapor-insulating and waterproof roofing system.

[0056] In some embodiments, the structural reinforcement 11 is selected from a steel mesh and a truss. The steel mesh can be a steel mesh with steel wires of different diameters or a steel mesh with different mesh sizes as required. The truss can be a truss including a plurality of trusses arranged at a certain interval to connect the vapor barrier layer, the thermal insulation layer, and the roof structure layer above it to enhance its structural strength.

[0057] In some embodiments, Figure 3 As shown, the vapor-insulating, heat-insulating and waterproof roofing system further includes a supporting structure member 12 arranged on a side of the structural reinforcement member 11 away from the vapor-insulating layer 5 .

[0058] In some embodiments, the supporting structure 12 is a purlin or a steel pipe beam to support the above-mentioned structural layer disposed thereon.

[0059] In some embodiments, Figure 2 and Figure 3 As shown, the vapor-insulating and heat-preserving and waterproof roofing system further includes a roll covering member 9 arranged on the roofing structure layer 7. The thermal insulation layer 6, the vapor-insulating layer 5, and the structural reinforcement member 11 are fixed to the supporting structure member 12 through the fixing member 10, and the roll covering member 9 is used to cover the fixing member 10 to prevent the fixing member 10 from being exposed to the external environment and damaged, thereby extending the service life of the vapor-insulating and heat-preserving and waterproof roofing system.

[0060] In one embodiment, the fixing member 10 is a steel screw, and the coiled material covering member 9 can completely cover the steel screw to prevent the steel screw from being exposed to the external environment and rusting or corroding, thereby extending the service life of the vapor insulation and waterproof roofing system. The coiled material covering member 9 can be made of the same material as the coiled material connecting member, so that the coiled material covering member 9 can be connected to the roof structure unit 70 of the same material by welding or hot melting, and connected to the roof structure layer 7 as a whole.

[0061] In some other optional embodiments of the present application, the vapor-insulating and waterproof roofing system further includes a fireproof layer, which is arranged between the roof structure layer and the thermal insulation layer, or between the vapor-insulating layer and the thermal insulation layer, or between the structural reinforcement and the vapor-insulating layer, or under the structural reinforcement. Under the premise of ensuring the vapor-insulating function, the fireproof function of the vapor-insulating and waterproof roofing system is increased, and the fireproof level of the vapor-insulating and waterproof roofing system is improved.

[0062] In some embodiments, the detailed nodes of the roof structure layer of the vapor-insulating, thermal-insulating and waterproof roof system, such as gaps and poorly sealed locations, can be flexibly processed through the roll material connector 8, which can solve the problem of water leakage in the detailed structure and make the vapor-insulating, thermal-insulating and waterproof roof system more waterproof.
