[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] With the progress and development of science and technology, waterproofing membranes are widely used in the construction industry. In the metal roofing industry, since the waterproofness of metal roofing panels cannot reach 100%, when metal roofing panels leak, it is very troublesome to check the leaking points, and it is necessary to set up another layer of waterproofing membrane as a drainage measure after the leak. Since the metal roofing panels need to be fixed on fixed supports, the fixed supports need to be fixed by drilling holes in the waterproofing membrane. For example, in a conventional public building, such nailing positions require tens of thousands or even hundreds of thousands, and the installation cost is high. Traditional color steel roof panels will peel off after a period of time due to the surface spray paint and plastic spraying, which affects the corrosion resistance of the roof panels. Local corrosion will penetrate, affecting indoor production and life and increasing maintenance costs.

[0028] In order to solve the problems of high maintenance cost of roof panel assemblies and water leakage in related technologies, the present invention provides a roof panel assembly. The technical solution of the roof panel assembly is described below in conjunction with the accompanying drawings.

[0029] Figure 1 This is a schematic diagram of the structure of the roof panel system according to an embodiment of the present disclosure. Figure 2 This is an enlarged schematic diagram of the fastening part of two roof panel components in the embodiment of the present disclosure. Figure 3 This is a schematic diagram of the structure of the roof panel assembly according to the embodiment of the present disclosure. Figures 1 to 3 As shown, an embodiment of the present disclosure provides a roof panel assembly 100 , which may include a metal roof panel 10 .

[0030] like Figure 3 As shown, specifically, the metal roof panel 10 includes a first portion 11 and second portions 12 located on both sides of the first portion 11. The first portion 11 is arranged in a flat plate shape, and the second portion 12 includes a connecting portion 121 and an extending portion 122, one end of the connecting portion 121 is connected to one end of the first portion 11, and the other end of the connecting portion 121 is connected to the extending portion 122. The connecting portion 121 is arranged obliquely relative to the first portion 11.

[0031] The metal roof panel 10 further includes a first buckle portion 13 and a second buckle portion 14. The first buckle portion 13 is disposed at one end of an extension portion 122 away from the first portion 11, and the second buckle portion 14 is disposed at one end of another extension portion 122 away from the first portion 11. The first buckle portion 13 and the second buckle portion 14 are adapted to each other so that the two roof panel assemblies 10 are buckled and connected through the first buckle portion 13 and the second buckle portion 14.

[0032] Exemplarily, the first part 11 is arranged in a flat plate shape, and the first part 11 may be square-shaped, and the second part 12 is arranged on one side of two opposite sides of the first part 11. The connecting portion 121 is arranged obliquely relative to the first part 11, and the inclination angle between the connecting portion 121 and the first part 11 is an acute angle. The extension portion 122 is connected to one end of the connecting portion 121, and the extension portion 122 extends in a direction away from the first part 11, so that the second part 12 forms an avoidance space relative to the plane where the first part 11 is located.

[0033] One of the second parts 12 on both sides is provided with a first buckling portion 13, and the other is provided with a second buckling portion 14, so that any two roof panel assemblies 100 can be assembled through the first buckling portion 13 and the second buckling portion 14 as needed, which facilitates the installation of the roof panel assembly 100.

[0034] In the roof panel assembly of the disclosed embodiment, the first buckling portion 13 and the second buckling portion 14 are provided on both sides of the first part 11 of the metal roof panel 10. When the metal roof panel 10 is installed, the first buckling portion 13 and the second buckling portion 14 of the two metal roof panels 10 are buckled and connected, so that the two roof panel assemblies are combined together. No fastener punching connection is required, and the waterproof performance of the roof panel assembly will not be damaged. Moreover, the roof panel assembly has good tightness after being combined, which improves the wind-resistant ability of the roof panel assembly and strengthens the overlap rigidity and waterproof functionality of the roof panel assembly.

[0035] Exemplarily, the first portion 11 , the second portion 12 , and the first buckling portion 13 and the second buckling portion 14 of the metal roof panel 10 are integrally formed, and the second portion 12 , the first buckling portion 13 and the second buckling portion 14 can be formed by bending the metal roof panel 10 .

[0036] In one embodiment, the metal roof panel 10 can be made of galvanized steel sheet, aluminum-plated steel sheet, aluminum-zinc-plated steel sheet, zinc alloy-plated steel sheet, aluminum sheet or stainless steel sheet. The metal roof panel 10 includes a base material layer and a protective layer, for example, the protective layer can be a galvanized layer, an aluminum-plated layer or the protective layer can also be an oxide layer on the surface of an aluminum sheet or a stainless steel sheet. The protective layer can play a good protective role on the base material layer of the metal material, thereby improving the corrosion resistance of the metal roof panel 10.

[0037] In one embodiment, the roof panel assembly 100 further includes a first waterproof roll material layer 20, the metal roof panel 10 includes a first surface (upper surface in the figure) and a second surface (lower surface in the figure) arranged opposite to each other, and the first waterproof roll material layer 20 is located on the first surface. The second surface can be attached to the roof, and the first waterproof roll material 20 can be attached to the first surface by an adhesive layer or welding, and the upper surface of the roof panel assembly 100 has a waterproof function.

[0038] When the roof panel assembly 100 is installed, since the first waterproof coiled material layer 20 is arranged on the first surface of the metal roof panel 10, nailing and fixing will not damage the waterproof coiled material, and the roof panel assembly has no hidden danger of water leakage, thereby ensuring the waterproof requirement.

[0039] Exemplarily, the material of the first waterproof roll material layer 20 includes thermoplastic polyolefin waterproof roll material and polyvinyl chloride waterproof roll material. The first waterproof roll material layer 20 can be formed by polymerizing ethylene propylene rubber and polypropylene to form a thermoplastic polyolefin synthetic resin base material, and adding antioxidants, anti-aging agents, etc. to form a waterproof material. The waterproof roll material can also use polyester fiber mesh cloth as a reinforcing material.

[0040] In the disclosed embodiment, the first waterproofing coiled material layer 20 of the roofing panel assembly adopts thermoplastic polyolefin waterproofing coiled material, which can have a service life of more than 30 years, and the first waterproofing coiled material layer 20 has the characteristics of strong environmental adaptability, high seam peeling strength, good aging resistance, excellent chemical corrosion resistance, good plasticity, energy saving and environmental protection, etc. The first waterproofing coiled material 20 also has excellent puncture resistance. Combining the first waterproofing coiled material 20 with the metal roofing panel 10 to form a fusion tile system can effectively solve the rust and aging of the traditional metal color steel roofing panel, and avoid the loss of waterproof functionality due to rust and aging.

[0041] It should be noted that the first waterproof roll material layer 20 may include but is not limited to a thermoplastic polyolefin waterproof roll material or a polyester fiber reinforced polyvinyl chloride roll material. The present disclosure does not limit the specific material of the first waterproof roll material layer, and it can be set according to actual design and use requirements.

[0042] In one embodiment, the thickness of the first waterproof roll material layer 20 is 0.2mm-1.8mm. Exemplarily, the first waterproof roll material layer 20 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm. In the case where the thickness of the first waterproof roll material layer 20 is less than 0.2mm, the first waterproof roll material layer 20 is easily damaged and broken, resulting in a decrease in waterproof performance. In the case where the thickness of the first waterproof roll material layer 20 is greater than 1.8mm, it may cause a waste of cost. Therefore, the embodiment of the present disclosure sets the thickness of the first waterproof roll material layer 20 to 0.2mm-1.8mm, and the thickness of the first waterproof roll material layer 20 is reasonable, which can ensure the waterproof performance of the first waterproof roll material layer 20, thereby effectively protecting the metal roof panel and ensuring the cost.

[0043] For example, in the embodiment of the present disclosure, the thickness of the first waterproof membrane layer 20 may be 1.5 mm, but is not limited thereto.

[0044] Exemplarily, the thickness of the metal roof panel 10 may be 0.4 mm to 0.8 mm. The metal roof panel 10 is combined with the first waterproof coiled material layer 20 by welding or bonding and then processed by a press forming process. For example, the thickness of the metal roof panel 10 may be 0.4 mm, 0.6 mm, and 0.8 mm, and the thickness of the metal roof panel 10 is not limited thereto.

[0045] In a specific embodiment, the metal roof panel 10 may be a 0.6 mm thick stainless steel metal plate.

[0046] Exemplarily, the width of the metal roof panel 10 is greater than the width of the first waterproof coiled material layer 20. After the first waterproof coiled material layer 20 is attached to the metal roof panel 10, a portion of the outer peripheral side of the metal roof panel 10 is not covered with the first waterproof coiled material layer 20. For example, the width of the metal roof panel 10 may be 600 mm, and the yield strength of the metal roof panel may be greater than or equal to 250 MPa. The width of the metal roof panel 10 is not limited thereto.

[0047] In one embodiment, the first waterproof roll material layer 20 is bonded to the first surface through a first bonding structure layer (not shown in the figure), the first bonding structure layer includes a metal layer and a first bonding layer and a second bonding layer located on opposite sides of the metal layer, the first bonding layer is bonded to the first waterproof roll material layer 20, and the second bonding layer is bonded to the metal roofing panel 10. Since the material of the metal roofing panel 10 is different from that of the first waterproof roll material layer 20, and the materials and bonding properties of the first bonding layer and the second bonding layer are different, when the two are bonded, by using the first bonding structure layer of this embodiment, the firmness of the bonding of the first waterproof roll material layer 20 can be ensured, and the installation of the first waterproof roll material layer 20 is also facilitated.

[0048] In one embodiment, the first waterproof roll material layer 20 includes a first waterproof portion 21, a second waterproof portion 22 and a third waterproof portion 23. The first waterproof portion 21 covers the surface of the first portion 11, the second waterproof portion 22 covers the surface of the connecting portion 121, and the third waterproof portion 23 is located on the surface of the extension portion 122 and is arranged at a certain distance from the first buckle portion 13 or the second buckle portion 14. That is, the surfaces of the first portion 11 and the connecting portion 121 are all covered with waterproof roll materials, and a part of the extension portion 122 is covered with waterproof roll materials, so that the use of waterproof roll materials can be reduced and the cost can be reduced while ensuring the waterproof performance requirements.

[0049] In this embodiment, by making the first waterproof part 21 cover the surface of the first part 11, the second waterproof part 22 cover the surface of the connecting part 121, and the third waterproof part 23 cover part of the surface of the extending part 122, the waterproof performance of the first waterproof membrane layer can be guaranteed, the metal roof panel can be effectively protected, and the cost can be reduced.

[0050] In one embodiment, the connecting portion 121 includes a first inclined portion 1211 and a second inclined portion 1212. One end of the first inclined portion 1211 is connected to one end of the first portion 11, and the other end of the first inclined portion 1211 is connected to the second inclined portion 1212. The other end of the second inclined portion 1212 is connected to the extension portion 122, and the inclination angle of the first inclined portion 1211 relative to the first portion 11 is smaller than the inclination angle of the second inclined portion 1212 relative to the first portion 11.

[0051] In this embodiment, the connecting portion 121 is set as a first inclined portion 1211 and a second inclined portion 1212, and the inclination angle of the first inclined portion 1211 relative to the first portion 11 is smaller than the inclination angle of the second inclined portion 1212 relative to the first portion 11. In this way, after the two roof panel assemblies are combined, the connecting portions 121 and the extending portions 122 of the two roof panel assemblies form a conical space with a small opening at the upper end and a large opening at the lower end, which is beneficial to improving the firmness of the roof panel assemblies after installation.

[0052] In one embodiment, the first buckling portion 13 includes a first vertical edge 131, a second vertical edge 132, and a third vertical edge 133. One end of the first vertical edge 131 is connected to the end of the extension portion 122, the second vertical edge 132 is bent 180° relative to the first vertical edge 131, and the third vertical edge 133 is bent 180° relative to the second vertical edge 132, and a circular slot is formed between the first vertical edge 131, the second vertical edge 132, and the third vertical edge 133.

[0053] The first vertical side 131 is vertically arranged relative to the extension portion 122, the second vertical side 132 is bent 180 degrees relative to the first vertical side 131, and the first vertical side 131 and the second vertical side 132 are connected through an arc-shaped end portion, the third vertical side 133 is located between the first vertical side 131 and the second vertical side 132, one end of the third vertical side 133 is connected to the second vertical side 132, and the end of the other end of the third vertical side 133 is spaced from the arc-shaped end portion. The first vertical side 131 and the third vertical side 133, the second vertical side 132 and the third vertical side 133 are combined to form a circular card slot.

[0054] The second buckling portion 14 includes a fourth vertical edge 141 and a fifth vertical edge 142. One end of the fourth vertical edge 141 is connected to the extension portion 122. The fifth vertical edge 142 is bent 180° relative to the fourth vertical edge 141. The fourth vertical edge 141 and the fifth vertical edge 142 are fixed in cooperation with the circular card slot. The fourth vertical edge 141 is in contact with the first vertical edge 131, and part of the fourth vertical edge 141 is located in the card slot between the second vertical edge 132 and the first vertical edge 131. The fifth vertical edge 142 is located in the card slot between the second vertical edge 132 and the third vertical edge 133, thereby achieving a 360° buckling between the first buckling portion 13 and the second buckling portion 14. The buckling strength of the first buckling portion 13 and the second buckling portion 14 is high, and the wind resistance is greatly improved.

[0055] The fourth vertical edge 141 and the fifth vertical edge 142 of the second buckling portion 14 can slide along the circular card slot to adjust the two roof panel components to be installed in place.

[0056] Reference Figures 1 to 3 As shown, the embodiment of the present disclosure further provides a roof panel system, which includes at least two roof panel assemblies 100 according to any embodiment of the present disclosure. Adjacent roof panel assemblies 100 are connected by a first buckle portion 13 and a second buckle portion 14.

[0057] The roof panel components 100 of the roof panel system of the embodiment of the present disclosure can be directly fixed by the first snap-fitting portion 13 and the second snap-fitting portion 14, without the need for fasteners to punch holes for connection, and will not damage the waterproof performance of the roof panel components. Moreover, the roof panel components have good tightness after being combined, thereby improving the wind-resistant ability of the roof panel system and strengthening the lap joint rigidity and waterproof functionality of the roof panel system.

[0058] Reference Figure 4 In one embodiment, the roof panel system further includes a buckle cover structure 200, which includes a buckle cover body 201. The buckle cover body 201 is wrapped and fitted on the buckle fitting part of the adjacent roof panel assembly 100, and the buckle cover body 201 is at least partially fitted with the connecting portion 121.

[0059] Exemplarily, the buckle cover body 201 includes a top plate, side plates located on both sides of the top plate, and a raised portion protruding from the middle of the top plate. The top plate and the two side plates form a first cover body, one end of the raised portion passes through the top plate, and the raised portion forms a second cover body. After the buckle cover body 201 is installed in place, the top plate fits with the third waterproof portion, the side plate fits with part of the second waterproof portion, and the first cover body is buckled on the extension portion and the connecting portion. The raised portion is buckled outside the first buckling portion 13. Therefore, by setting the buckle cover body 201, the buckling parts of the two roof panel assemblies 100 can be protected.

[0060] Exemplarily, the buckle cover body 201 can be formed by processing a metal sheet, and the material of the buckle cover body 201 is the same as that of the metal roof panel 10. The thickness of the buckle cover body 201 is different from that of the metal roof panel. For example, both the metal roof panel 10 and the buckle cover body 201 can be made of galvanized steel sheet, the buckle cover body 201 can be made of a galvanized steel sheet with a thickness of 0.8 mm, and the metal roof panel 10 can be made of a galvanized steel sheet with a thickness of 0.6 mm.

[0061] The roof panel system of the disclosed embodiment protects the outer side of the roof panel assembly by the first waterproof membrane layer, thereby improving the anti-aging ability of the roof panel assembly, and fastens two adjacent roof panel assemblies by the first fastening portion and the second fastening portion, which will not damage the waterproof performance of the roof panel system. A buckle cover structure is provided at the bite position of the two roof panel assemblies to increase the service life of the roof panel system.

[0062] In one embodiment, the buckle cover structure 200 also includes a second waterproof membrane layer 202, the buckle cover body 201 includes a first side and a second side arranged opposite to each other, the first side is bonded to the metal roof panel, and the second waterproof membrane layer 202 is bonded to the second side through a second adhesive structure layer.

[0063] Exemplarily, the material of the second waterproof roll material layer 202 is the same as that of the first waterproof roll material layer, and the thickness of the second waterproof roll material layer 202 is different from that of the first waterproof roll material layer. For example, the first waterproof roll material layer may be a thermoplastic polyolefin waterproof roll material with a thickness of 0.2 mm, and the second waterproof roll material layer may be a thermoplastic polyolefin waterproof roll material with a thickness of 1.8 mm.

[0064] For example, the material of the second waterproof roll layer 202 may include, but is not limited to, a thermoplastic polyolefin waterproof roll and a polyester fiber reinforced polyvinyl chloride roll. The present disclosure does not limit the specific material of the first waterproof roll layer, and it can be set according to actual design and use requirements.
