Description

Technical Field

[0001] The utility model relates to the technical field of metal roof systems, in particular to a film-coated metal roof panel system. Background Art

[0002] Metal roofing system has become the preferred solution for industrial and commercial building roofs due to its short construction period and high cost-effectiveness. This system is mainly composed of structural purlins, metal roof panels connected to the purlins, and an optional functional layer located between the purlins and the roof panels. Among them, the metal roof panels are directly exposed to the external environment, such as direct sunlight and rain erosion. Its anti-corrosion performance and the connection method with the structural purlins are the key to determining the life of the entire roof system.

[0003] In early designs, metal roof panels were fixed to the purlins by penetrating screws. However, this fixing method cannot adapt to the thermal expansion and contraction of the roof panels due to temperature changes, causing the screws to loosen or break, thereby shortening the effective life of the system. In addition, penetrating screws will squeeze the functional layer, which does not meet the requirements of modern buildings. For this reason, the design of the metal roof system has been improved to adopt a crimping connection method. In this method, adjacent roof panels are interlocked and locked with brackets fixed to the purlins through male and female buckles. This flexible connection design allows limited movement of the roof panels during thermal expansion and contraction, thereby avoiding connection failure.

[0004] However, despite this, there are still some problems with the metal roofing system with rolled-edge bite connection. For example, it is difficult to achieve long-term sealing at flashing parts such as ridges and skylights, the bite parts are easily affected by capillary water absorption and corrosion deformation, and the exposed metal plate cut edges are easily eroded by rainwater. In order to solve these problems, a feasible solution is to use a flexible waterproof membrane to bond and cover the surface of the metal roof panel after it is installed. However, due to the complex profiled structure of the roof panel, this solution is extremely difficult to construct and has a high overall cost. Utility Model Content

[0005] The utility model aims to provide a membrane-laminated metal roof panel system to solve the problems of great construction difficulty and high comprehensive cost of the existing metal roof system waterproof system.

[0006] The utility model is implemented as follows: a film-coated metal roof panel system, which includes a profiled film-coated metal plate and an inverted V-shaped self-adhesive profile;

[0008] The inverted V-shaped self-adhesive profile is provided with a release film, a pressure-sensitive adhesive layer, a closed-cell foam layer and a flexible waterproof film main body layer from bottom to top, and each layer is bonded to each other to form an inverted V shape;

[0009] The inverted V-shaped self-adhesive profile is pasted on the top of the two ribs after biting, and is welded to the flexible waterproof membrane of the profiled laminated metal plate.

[0012] Preferably, the thickness of the main layer of the flexible waterproof membrane of the inverted V-shaped self-adhesive profile is between 0.6-2.0 mm, and an arc-shaped thickening design is adopted at the corners to compensate for stress concentration.

[0013] Preferably, the main layer of the flexible waterproof membrane in the inverted V-shaped self-adhesive profile is made of the same material as the flexible waterproof membrane on the metal plate body.

[0014] Preferably, the angle between the rib and the metal plate body is 60°; and the top angle of the inverted V-shaped self-adhesive profile is 60°.

[0015] Preferably, the flexible waterproof membrane is made of one of a flexible thermoplastic polyolefin (TPO) membrane and a flexible polyvinyl chloride (PVC) membrane.

[0028] like Figure 1-Figure 6 As shown, a film-faced metal roof panel system includes a profiled film-faced metal panel and an inverted V-shaped self-adhesive profile.

[0029] The corrugated film-laminated metal sheet comprises a metal sheet body 1 and ribs 2 arranged at both ends thereof, which are respectively inclined outward and upward, and a snap buckle 3 is arranged on the top of the rib 2. The corrugated film-laminated metal sheets can be spliced ​​with each other and fixed on the purlins to form a metal roofing system, which has the characteristics of short construction period and low construction difficulty. The metal sheet can be a galvanized steel sheet, a titanium zinc sheet, an aluminum magnesium manganese sheet or an aluminum alloy sheet, with a thickness between 0.6-1.0mm. A corrugation 4 is arranged on the metal sheet body 1, and the number of the corrugation 4 can be one, which is arranged in the middle of the metal sheet body 1; or it can be several, which are evenly spaced and arranged on the metal sheet body 1. The cross-section of the corrugation 4 can be a trapezoid or other shapes, which are used to enhance the strength of the metal sheet body 1 or avoid the protruding structure of the roof. The edge of the corrugation 4 is at least 70mm away from the bottom edge of the ribs 2 on both sides, and other areas are corrugated 4 according to the roof strength design requirements.

[0030] Furthermore, an adhesive film 5 and a flexible waterproof film 6 are sequentially arranged on the upper surface of the metal plate body 1. The flexible waterproof film 6 is made of a flexible thermoplastic polyolefin (TPO) film or a flexible polyvinyl chloride (PVC) film, has good hot air welding performance, has a thickness of 0.6-2.0 mm, and has color options including white, light gray or brown with high solar reflectance. The adhesive film 5 and the flexible waterproof film 6 make the metal plate body 1 waterproof and extend the service life of the metal plate body 1. Furthermore, the adhesive film 5 and the flexible waterproof film 6 do not cover the ribs 2 at both ends of the metal plate body 1, so that the subsequent installation can normally perform the crimping bite process.

[0031] The lamination process of the metal plate body 1 is completed in advance in the factory, and the pressing 4 can be completed in the factory or on the construction site.

[0032] The inverted V-shaped self-adhesive profile of the utility model is provided with a release film 7, a pressure-sensitive adhesive layer 8, a closed-cell foam layer 9 and a flexible waterproof film main body layer in order from bottom to top. The flexible waterproof film main body layer is made of the same material as the flexible waterproof film 6 covered on the above-mentioned metal plate body. The layers are bonded to each other and form an inverted V shape. The height and angle design should be matched with the ribs 2 and the snap buckles 3 after the bite connection. The inverted V-shaped self-adhesive profile is pasted on the top of the two ribs after the bite. The bottom of the flexible waterproof film main body layer of the uppermost layer of the inverted V-shaped self-adhesive profile extends to both sides, and the closed-cell foam layer 9, the pressure-sensitive adhesive layer 8 and the release film 7 are not provided within the 30-50mm width range near its edge, so as to perform hot air welding with the flexible waterproof film 6 below.

[0033] Furthermore, the thickness of the flexible waterproof membrane is between 0.6-2.0 mm, and the corners are designed with arc-shaped thickening to compensate for stress concentration. The color is selected to be white, light gray or brown with high solar reflectance. The closed-cell foam layer has a density of 300-600 kg / m3 and a thickness range of 0.4-2.0 mm. The thickness of the pressure-sensitive adhesive layer ranges from 0.05-0.3 mm.

[0034] Furthermore, the included angle between the rib plate and the metal plate body is 60°. The included angle of the top of the inverted V-shaped self-adhesive profile is 60°.

[0035] During the installation of the roof panel, the profiled laminated metal sheet is first installed on the fixed bracket through the bite process. Then, the release film of the inverted V-shaped self-adhesive profile is removed and pasted on the metal plate ribs after the bite connection. Finally, the reserved welding areas on both sides of the profile are welded to the main layer of the flexible waterproof membrane on the surface of the profiled laminated metal sheet.

[0036] As shown in the figure, Example 1: 470 type vertical lock seam laminated metal roof panel system; the metal panel body is made of 0.9mm aluminum alloy plate, and a 1.8mm thick white flexible thermoplastic polyolefin (TPO) waterproof membrane is hot-pressed and compounded in the factory through an adhesive film. The rib areas on both sides are not coated. The profiling is based on the 470 panel design, with an effective width of 470mm, a rib height of 76mm, a rib angle of 60°, and a 5mm high boss is used in the center area of ​​the panel to strengthen the profiling.

[0037] The main layer of the inverted V-shaped self-adhesive profile is made of white flexible thermoplastic polyolefin (TPO) raw material by extrusion, with a thickness of 1.8mm, an inverted V-shaped angle of 60°, a height of 77mm, and an arc-shaped thickening treatment at the corners. A 1.0mmTPO closed-cell foam layer is designed inside the profile, and the surface of the closed-cell foam layer is coated with 0.2mm acrylic pressure-sensitive adhesive, and the surface of the pressure-sensitive adhesive is covered with an anti-sticking release film. The inverted V-shaped bottom extends 60mm to both sides, and the outermost 40mm is not provided with a closed-cell foam layer and pressure-sensitive adhesive.

[0038] As shown in the figure, Example 2: 820 type upright lock seam laminated metal roof panel system; the metal panel body is made of 0.8mm galvanized steel plate, and a 1.2mm thick brown flexible polyvinyl chloride (PVC) waterproof membrane is hot-pressed and compounded in the factory through an adhesive film. The rib areas on both sides are not laminated, and the profiling is based on the Jiaochi III type design, with an effective width of 820mm, a rib height of 51mm, and a rib angle of 60°. A snap-fit ​​rib is set in the center area of ​​the panel. The snap-fit ​​rib details are complicated to profile, so they are not laminated either.

[0039] The main layer of the inverted V-shaped self-adhesive profile is made by extrusion of brown flexible polyvinyl chloride (PVC) raw material, with a thickness of 1.2mm, an inverted V-shaped angle of 60°, a height of 52mm, and an arc-shaped thickening treatment at the corners. A 0.6mm PVC foam layer is designed inside the profile, and the surface of the foam layer is coated with 0.1mm acrylic pressure-sensitive adhesive, and the surface of the pressure-sensitive adhesive is covered with an anti-sticking release film. The inverted V-shaped bottom extends 60mm to both sides, and the outermost 40mm is not provided with a foam layer and pressure-sensitive adhesive.

[0040] As shown in the third embodiment of the figure: 980 type vertical lock seam film-coated metal roof panel system; the metal plate body is made of 0.7mm galvanized steel plate, and a 1.2mm thick light gray flexible thermoplastic polyolefin (TPO) waterproof membrane is hot-pressed and compounded in the factory through an adhesive film. The rib areas on both sides are not coated. After pressing, the effective width is 980mm, the rib height is 30mm, and the rib angle is 60°.

[0041] The main layer of the inverted V-shaped self-adhesive profile is made of light gray flexible thermoplastic polyolefin (TPO) raw material by extrusion, with a thickness of 1.2mm, an inverted V-shaped angle of 60°, a height of 31mm, and an arc-shaped thickening treatment at the corners. A 0.4mm TPO foam layer is designed inside the profile, and the surface of the foam layer is coated with 0.05mm acrylic pressure-sensitive adhesive, and the surface of the pressure-sensitive adhesive is covered with an anti-sticking release film. The inverted V-shaped bottom extends 60mm to both sides, and the outermost 40mm is not provided with a foam layer and pressure-sensitive adhesive.

[0042] This type of board has a larger span and is suitable for building roofs with lower wind-resistant design requirements.

[0043] In the utility model, the waterproof coating layer is arranged above the metal plate body, so that the metal roof panel is included in the waterproof protection category as a whole, effectively extending the overall service life of the metal roof system. In addition, by adopting the metal plate pre-coating and profile pre-forming process, compared with the traditional metal roof panel post-coating solution, the process flow and construction difficulty are greatly simplified, thereby reducing the overall cost of the entire metal roof system.

[0044] Using an inverted V-shaped self-adhesive profile with a foam layer and a self-adhesive layer, this design can perfectly fit the bite ribs of the metal roof panel, effectively prevent the erosion of rain on the bite part, and reduce the impact of temperature changes on the bite part, thereby improving the long-term reliability of the bite part.

[0045] In addition, the main layer of the inverted V-shaped self-adhesive profile of the present application and the film of the film-coated metal sheet are made of the same material, and the upper surface of the metal roof panel is completely covered by welding. This design reduces the requirements for the flashing height of the bite ribs, allowing the height of the bite ribs to be reduced to improve the utilization rate of the metal sheet and reduce the cost of the entire metal roof system. At the same time, the flashing parts such as the ridge and skylight can be welded and covered with a flexible waterproof membrane of the same material, effectively overcoming the treatment difficulties of the flashing parts of the metal roof and the rainwater corrosion problem of the cut edges of the exposed metal plates.

[0046] Finally, the high solar reflectance characteristics of the profiles and coatings in this application help reduce the exposure temperature of the building surface, thereby reducing energy consumption indoors.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
