[0036] 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.

[0037] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0038] like Figure 1 and Figure 2 As shown, the first exemplary embodiment of the present application provides a roofing system, which includes a penetration assembly 2 and a plurality of roofing sandwich panels 1 for splicing and laying on the purlin A of the roof, wherein the roofing sandwich panel 1 includes an upper steel plate 101 and a lower steel plate 102 sealed and spliced ​​from top to bottom, and the spliced ​​upper steel plate 101 and the lower steel plate 102 can be combined into a steel plate shell of the roofing sandwich panel 1. The roofing sandwich panel 1 also includes an insulation layer 103 arranged in a cavity defined by the upper steel plate 101 and the lower steel plate 102.

[0039] The roof sandwich panel 1 has a tenon portion 104 and a step portion 105 formed at both transverse ends, wherein the tenon portion 104 of one of the two mutually spliced ​​roof sandwich panels 1 overlaps the step portion 105 of the other to form a tongue and groove together, and the connecting component 2 connects the top wall and the bottom wall of the tenon portion 104 and the top wall and the bottom wall of the step portion 105. Since the top wall and the bottom wall of the tenon portion 104 and the top wall and the bottom wall of the step portion 105 are all steel plate structures, the connecting component 2 connects at least four layers of steel plates to achieve a stable connection between the two roof sandwich panels 1.

[0040] It can be seen that the roofing system of this exemplary embodiment can form a steel plate shell that is sealed from top to bottom by setting an upper steel plate 101 and a lower steel plate 102. The hemming of the steel plate shell at both ends of the transverse direction is complete, and the structural strength and fireproof level are high. The key is that the lateral ends of the roofing sandwich panel 1 form a convex tenon portion 104 and a step portion 105, respectively, so that the two roofing sandwich panels 1 can be connected to each other in the form of a tongue and groove, effectively eliminating the gap between the two roofing sandwich panels 1, and ensuring that the roofing system has high waterproofness and airtightness. In addition, by using the connection component 2 to simultaneously connect the convex tenon portion 104 and the step portion 105 that overlap each other, the connection strength of the two roofing sandwich panels 1 can be improved, and the load resistance of the roofing system can be improved.

[0041] It should be noted that the thickness of the insulation layer 103 of this exemplary embodiment can be 30mm-300mm, and the insulation material can be selected from rock wool, polyurethane, glass wool, polystyrene foam, etc. to improve the fire protection level. The thickness of the upper steel plate 101 and the lower steel plate 102 can be 0.3mm-1.8mm, and the surface of the steel plate can be electroplated, such as galvanizing, aluminum-zinc plating, galvanized aluminum-magnesium plating, aluminum-magnesium-manganese plating, etc., or an aluminum plate shell can be used, which is not limited in this embodiment.

[0042] Reference Figure 2 A splicing seam 3 located above the tongue and groove is formed between the lateral ends of the two roof sandwich panels 1 spliced ​​to each other, and the splicing seam 3 can be used for the connecting component 2 to connect the tongue and groove position and hide the top of the connecting component 2. In order to ensure that the air tightness of the connecting position and the splicing position is high, the roofing system also includes a seam insulation layer 4 filling the splicing seam 3, wherein the seam insulation layer 4 can cover the connection position between the convex tenon portion 104 and the step portion 105, especially the connecting position of the connecting component 2, that is, the screw hole formed after the connecting component 2 connects the convex tenon portion 104 and the step portion 105, thereby preventing condensation from occurring. In this embodiment, the seam insulation layer 4 can be prepared by foaming materials, rubber, resin and the like, and this embodiment does not limit this.

[0043] Furthermore, at least one waterproof layer can be optionally provided above the seam insulation layer 4. To this end, the roofing system also includes a seam waterproof layer 5, which can cover the seam insulation layer 4 and seal the connection position between the seam insulation layer 4 and the lateral end of the roof sandwich panel 1, thereby ensuring that the spliced ​​seam 3 has a better waterproof effect.

[0044] In an optional or preferred embodiment, referring to Figure 2The through-connection assembly 2 includes a screw 201, a screw washer 202 and a protective cover 203, wherein the screw washer 202 is disposed between the nut of the screw 201 and the top wall of the tenon portion 104, which can further play a role in waterproofing and heat preservation, and the protective cover 203 covers the nut and is located below the sandwich insulation layer 4, which can effectively prevent the screw 201 from being corroded and prolong the service life. Of course, the two roof sandwich panels spliced ​​together also include but are not limited to riveting, welding, bonding, bolting, etc.

[0045] Reference Figure 2 The cavity defined by the upper steel plate 101 and the lower steel plate 102 includes a first end insulation cavity and a second end insulation cavity respectively located at the two lateral ends, and a main insulation cavity located between the first end insulation cavity and the second end insulation cavity, wherein the main insulation cavity accommodates an insulation layer 103, the first end insulation cavity includes an inner cavity of the tenon portion 104 and is filled with a first insulation material 106, and the second end insulation cavity includes an inner cavity of the step portion 105 and is filled with a second insulation material 107.

[0046] In the illustrated embodiment, the first thermal insulation material 106 and the second thermal insulation material 107 are composed of the same material, and the thermal insulation layer 103 is composed of other different materials, but the present application is not limited to this. The thermal insulation layer 103, the first thermal insulation material 106 and the second thermal insulation material 107 can also be composed of the same material, or at least two of the three can be composed of different materials. Among them, the first thermal insulation material 106 and the second thermal insulation material 107 can select the above-mentioned materials used to constitute the thermal insulation layer 103, so they are not repeated here.

[0047] In an alternative or preferred embodiment, referring to Figure 2 The roof sandwich panel 1 also includes a waterproof roll 108 laid on the top surface of the upper steel plate 101. Generally, a polymer roll such as a TPO roll, a PVC roll, etc. can be selected as the waterproof roll 108. In addition, one of the two lateral ends of the waterproof roll 108 is formed as an extension end 1081 that is arranged beyond the lateral end of the roof sandwich panel 1. Therefore, in the two mutually spliced ​​roof sandwich panels 1, the extension end 1081 of the waterproof roll 108 of one can be overlapped on the waterproof roll 108 of the other to form two layers of waterproof roll 108, and the two layers of waterproof roll 108 are welded together by hot air welding, so that the extension end 1081 can seal the splicing gap 3, thereby ensuring that the roof system has extremely high sealing performance, and at the same time, the upper surface of the roof system can be flat and flawless.

[0048] Correspondingly, such as Figure 3As shown, the second exemplary embodiment of the present application also provides a roofing sandwich panel 1, which includes an upper steel plate 101 and a lower steel plate 102 sealed and spliced ​​together, and an insulation layer 103 arranged in a cavity defined by the upper steel plate 101 and the lower steel plate 102, and a tenon portion 104 and a step portion 105 are respectively formed at the two lateral ends of the roofing sandwich panel 1.

[0049] In an optional or preferred embodiment, the cavity defined by the upper steel plate 101 and the lower steel plate 102 includes a first end insulation cavity and a second end insulation cavity respectively located at the two lateral ends, and a main insulation cavity located between the first end insulation cavity and the second end insulation cavity, wherein the main insulation cavity accommodates an insulation layer 103, the first end insulation cavity includes an inner cavity of the tenon portion 104 and is filled with a first insulation material 106, and the second end insulation cavity includes an inner cavity of the step portion 105 and is filled with a second insulation material 107.
