[0032] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0033] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0034] like Figure 1 and Figure 2 As shown, the first exemplary embodiment of the present application provides a roof structure, which includes a through-connection component 1 and a plurality of composite panels 2 for splicing and laying on the roof, the lateral ends of the composite panel 2 are respectively formed as a first splicing end 201 and a second splicing end 202, the top wall of the first splicing end 201 protrudes upward to form a crest portion 203, and a waterproof roll 204 is laid on the top of the composite panel 2, and the portion of the waterproof roll 204 located at the second splicing end 202 extends outward to form a roll overlap portion 2041.

[0035] In the two composite panels 2 spliced ​​together, the first splicing end 201 of one is spliced ​​to the second splicing end 202 of the other. For example, the first splicing end 201 and the second splicing end 202 are connected to each other by overlapping. The specific connection forms and structures are listed below. The top wall of the crest portion 203 is provided with a through-connection position, and the through-connection position may be provided with a recognizable mark or structure, etc., which is not limited in this application. The through-connection component 1 is arranged to connect the top wall and the bottom wall of the first splicing end 201 from the through-connection position. In other words, the through-connection component 1 is connected from the top wall of the crest portion 203 to the bottom wall of the first splicing end 201. In actual application, the through-connection component 1 can connect the first splicing end 201 and the roof purlin, thereby fixing one of the composite panels 2 on the roof. The coiled material overlapping portion 2041 is overlapped at the first splicing end 201 , and the coiled material overlapping portion 2041 can at least cover the threading position, that is, can cover the threading component 1 located at the threading position.

[0036] In general, in the roof structure of this exemplary embodiment, two adjacent composite panels 2 can be spliced ​​together through their respective first splicing ends 201 and second splicing ends 202. The coiled material overlap portion 2041 extending outward from the second splicing end 202 can overlap the crest portion 203 of the first splicing end 201, so that the coiled material overlap portion 2041 is lifted by the crest portion 203, effectively preventing rainwater from penetrating the overlap seam between the coiled material overlap portion 2041 and the crest portion 203 into the splicing seam between the two composite panels 2, thereby improving the waterproofing effect of the entire roof structure. The key point is that the crest portion 203 increases the thickness of the first splicing end 201, thereby effectively offsetting the cold bridge formed at this location. Since the roof structure is composed of multiple composite panels 2 spliced ​​together, it is possible to eliminate cold bridges between multiple adjacent composite panels 2, effectively reducing the number and area of ​​cold bridges in the entire roof structure, and significantly improving the thermal insulation effect of the roof structure.

[0037] Furthermore, by threading the connecting assembly 1 through the first splicing end 201 and overlapping the coiled material overlap portion 2041 with the first splicing end 201, for example by welding the coiled material overlap portion 2041, the first splicing end 201 can be secondary reinforced, thereby improving the connection stability between the two composite panels 2. Furthermore, the coiled material overlap portion 2041 covers the threading position, effectively sealing the threading joint between the connecting assembly 1 and the first splicing end 201, preventing rainwater from seeping into the roof structure through the threading joint, thereby further improving its waterproofing effect.

[0038] It should be noted that in actual application, Figure 2 As shown, the overlapping portion 2041 of the rolled material can be deformed to form a shape similar to the outer contour of the crest portion 203, so that it can fit the crest portion 203 for overlapping and covering, thereby improving the waterproof and tear-resistant effects of the overlapping portion 2041 of the rolled material.

[0039] In one embodiment, referring to Figure 2 The inner sidewall of the crest portion 203 forms a limiting groove 2031, and the coiled material overlap portion 2041 also covers the inner sidewall of the crest portion 203. The coiled material overlap portion 2041 also has a coiled material protrusion 2042 that nests within the limiting groove 2031. The arrangement of the coiled material overlap portion 2041 covering the inner sidewall of the crest portion 203 ensures both waterproofing of the entire crest portion 203 and the stability of the connection itself. Furthermore, by nesting the coiled material protrusion 2042 within the limiting groove 2031, the stability of the coiled material overlap portion 2041 is enhanced. The key is that in the process of splicing two composite panels 2, the roll material overlapping portion 2041 of the composite panel 2 to be spliced ​​later can be overlapped on the crest portion 203 of the composite panel 2 installed earlier, and the roll material protrusion 2042 can be nested in the limiting groove 2031 to play a temporary positioning role, and then the second splicing end 202 of the composite panel 2 installed later can be accurately docked with the composite panel 2 installed earlier, thereby reducing the difficulty of splicing between the two composite panels 2, and can fully spread out the roll material protrusion 2042 to prevent it from moving and forming a water seepage point.

[0040] In an optional or preferred embodiment, a tongue-and-groove portion 205 is formed at the bottom of one of the first splicing end 201 and the second splicing end 202 of the composite panel 2, and a tenon portion 206 matching the tongue-and-groove portion 205 is formed at the bottom of the other. In the two spliced ​​composite panels 2, the tenon portion 206 of one is inserted into the tongue-and-groove portion 205 of the other, thereby improving the connection stability between the two spliced ​​composite panels 2 and enhancing both wind and pressure resistance. It is understood that when the tongue-and-groove portion 205 is formed at the first splicing end 201, the tenon portion 206 is correspondingly formed at the second splicing end 202, and vice versa, and this application is not limited thereto.

[0041] In addition, the present application does not limit the specific shape of the mortise portion 205 and the tenon portion 206, which can be various regular or irregular shapes such as rectangle, triangle, wedge, etc., as long as the two can form a plug-in fit. Figure 1 and Figure 2 As shown, the top surfaces of the tenon portion 206 and the tenon groove portion 205 are both formed as inclined top surfaces, and the bottom surfaces are both formed as flat bottom surfaces. In this way, the outer end of the tenon portion 206 forms an outward-retracted tip, and the outer opening of the tenon groove portion 205 forms an outward-expanding opening, so that the tenon portion 206 can be easily aligned with the tenon groove portion 205 for insertion.

[0042] In particular, when splicing two composite panels 2, after the coiled material overlap portion 2041 of the composite panel 2 installed later overlaps the composite panel 2 installed earlier, the first splicing end 201 of the composite panel 2 installed later can be raised to a certain angle, and then the coiled material protrusion 2042 of the coiled material overlap portion 2041 is nested in the limiting groove 2031. The raised composite panel 2 is then laid flat, so that the tenon portion 206 slowly fits into the tenon groove portion 205, thereby completing the splicing of the two composite panels 2. During the process of laying the composite panel 2 installed later flat, since the top surface of the tenon portion 206 is an inclined top surface, the tenon portion 206 can undergo a certain deformation, allowing it to smoothly fit into the tenon groove portion 205, and the coiled material overlap portion 2041 can gradually wrap around the entire crest portion 203, achieving a fully fitted state.

[0043] In an optional or preferred embodiment, Figure 2As shown, the through-connection assembly 1 includes a screw 101 and a screw washer 102. The top wall of the wave peak portion 203 located at the through-connection position is concave to form a receiving groove 2032 for accommodating the nut of the screw 101 and the screw washer 102. The screw washer 102 is arranged between the nut and the bottom wall of the receiving groove 2032. As a result, the nut of the screw 101 and the screw washer 102 do not protrude from the top wall of the wave peak portion 203, so that the coiled material overlapping portion 2041 can be arranged to smoothly cover the top wall of the wave peak portion 203, thereby preventing the top of the through-connection assembly 1 from causing damage to the coiled material overlapping portion 2041. At the same time, the notch of the receiving groove can also be used to facilitate the removal of the through-connection assembly 1, so as to facilitate the replacement or maintenance of the composite board 2.

[0044] In some other embodiments, the connecting component 1 can also be completely inserted into the first splicing end 201, which is not limited in this application.

[0045] In an optional or preferred embodiment, Figure 1 As shown, the composite panel 2 includes a waterproof coil 204, a metal top plate 207, an insulation layer 208, and a metal bottom plate 209, which are stacked in sequence. The insulation layer 208 includes a first insulation material layer 2081 and a second insulation material layer 2082 that circumferentially surrounds the first insulation material layer 2081. The second insulation material layer 2082 is filled in at least the first splicing end 201 and the second splicing end 202. The metal top plate 207 and the metal bottom plate 209 are both capable of wrapping around the first splicing end 201 and the second splicing end 202, thereby enhancing the strength of the composite panel 2, especially preventing damage to the two lateral ends, thereby improving the splicing quality and the waterproof and thermal insulation effects.

[0046] In this embodiment, the first thermal insulation material layer 2081 can be an inorganic fiber insulation layer such as a rock wool insulation layer and a glass wool insulation layer, and the second thermal insulation material layer 2082 can be a polyurethane insulation layer. Since the polyurethane insulation layer has a certain hardness, the second thermal insulation material layer 2082 can form a protective effect on the first thermal insulation material layer 2081, which not only enhances the strength of the entire composite panel 2 and reduces the risk of damage during transportation and splicing, but also can isolate water vapor and water in the air from entering the first thermal insulation material layer 2081, effectively avoiding its thermal insulation failure.

[0047] The second exemplary embodiment of the present application provides a composite plate, such as Figure 1 As shown, the lateral ends of the composite panel 2 are respectively formed as a first splicing end 201 and a second splicing end 202, the top wall of the first splicing end 201 protrudes upward to form a crest portion 203, and a waterproof roll 204 is laid on the top of the composite panel 2. The waterproof roll 204 includes a roll overlap portion 2041 extending outward from the second splicing end 202, and the top wall of the crest portion 203 is provided with a connection position for the connection component 1 to be passed through.

[0048] Thus, two composite panels 2 can be spliced ​​together via the first splicing end 201 and the second splicing end 202. The first splicing end 201 can be threaded through the crest portion 203 via the through-connection assembly 1 and fixed to the roof purlin. The coiled material overlap portion 2041 of one composite panel 2 can overlap the crest portion 203 of the other composite panel 2, thereby raising the overlap seam. Overall, the composite panels 2 of this exemplary embodiment are easy to install, effectively eliminate cold bridges at the ends, and provide better thermal insulation performance.

[0049] In an optional or preferred embodiment, a limiting groove 2031 is formed on the inner side wall of the crest portion 203 , and a coil protrusion 2042 for being nested in the limiting groove 2031 of another composite panel 2 is formed on the coil overlapping portion 2041 .

[0050] In an optional or preferred embodiment, a tongue and groove portion 205 is formed at the bottom of one of the first splicing end 201 and the second splicing end 202 , and a tenon portion 206 matching the tongue and groove portion 205 is formed at the bottom of the other splicing end.

[0051] In an optional or preferred embodiment, the top wall of the crest portion 203 at the threading position is concave to form a receiving groove 2032 for accommodating part of the threading component 1.

[0052] In an optional or preferred embodiment, the composite panel 2 includes a waterproof roll 204, a metal top plate 207, an insulation layer 208 and a metal bottom plate 209 stacked in sequence, the insulation layer 208 includes a first insulation material layer 2081 and a second insulation material layer 2082 circumferentially covering the first insulation material layer 2081, and the second insulation material layer 2082 is filled in at least the first splicing end 201 and the second splicing end 202.

[0053] In this embodiment, the waterproof roll 204 can be a polymer-fiber composite roll with high tensile strength, tear resistance and strong adhesive strength. The first insulation material layer 2081 can adopt an inorganic fiber insulation layer such as rock wool insulation layer, glass wool insulation layer, etc., and the second insulation material layer 2082 can adopt a polyurethane insulation layer.
