Description

Technical Field

[0001] The invention relates to the technical field of building installation, and more specifically, to a metal roof panel installed with a photovoltaic panel. Background Art

[0002] The metal roof photovoltaic panel system has been used in my country for a long time. Because of its green and pollution-free characteristics, it has been widely used in many areas, especially in areas with sufficient sunlight, where photovoltaic panels can play a big role.

[0003] Since it is installed on the roof, the wind resistance of the entire system is the most critical. There are two traditional processes for installing photovoltaic panels on metal roofs. The first BAPV (Building Attached Photovoltaics) is to use a special aluminum alloy bracket to fix the keel on the vertical locking edge of the roof panel on the completed metal structure roof panel, and then install the sub-frame on the keel or directly use an aluminum alloy special clamp to fix the welded combination bracket, then install the aluminum profile keel frame, and finally install the solar panel assembly. This construction process has general wind resistance and requires the installation of secondary keels. The construction steps are numerous and the efficiency is low. The second BIPV (Building Integrated PV) is to directly install a fixed support on the completed metal structure, then install a locking clip on the fixed support, and finally fix the photovoltaic panel with the locking clip. The photovoltaic panel installed in this way will directly serve as a component of the building, playing the role of light transmission, wind and rain protection, and heat insulation. Although this method does not require the installation of secondary keels, the structure is too simple, the wind resistance is general, and because the support is fixed, the thermal expansion and contraction have a greater impact on it.

[0045] The vertical plate 121, the V-shaped plate 122, and the middle plate 123 are connected in sequence from bottom to top. The two wing plates of the V-shaped plate 122 are symmetrical about the center plane formed by the middle plate 123 and the vertical plate 121. The two sides of this center plane can respectively support a locking plate 22 adapted thereto.

[0046] In a specific embodiment of the present invention, in order to adapt to the connecting bracket 1, the locking plate 22 includes an arc plate 221, a connecting plate 222 and a metal bent plate 223 connected in sequence from top to bottom, and an inclined plate 224 is connected to the lower edge of the metal bent plate 223, and the lower edge of the inclined plate 224 is connected to the panel 21.

The arc plate 221 can bypass the support block 124. The arc surface on the upper part of the support block 124 can stably support the inner side of the arc plate 221. The inclined plate 224 is connected to the panel 21 by the lower end of the metal bent plate 223. The inclination of the inclined plate 224 can be convenient for connecting to the panel 21.

Multiple connecting brackets 1 can be evenly arranged to jointly support and compress the locking plate 22 for fixed stability.

[0052] In this embodiment, the three-pronged connecting bracket 1 enables the metal roof panel to have a wind-resistant self-locking function. The stronger the wind, the tighter the locking plate 22 is locked, which greatly improves the wind resistance of the metal roof panel equipped with photovoltaic panels.

[0053] In a specific embodiment of the present invention, a limiting block 133 is provided on the inner side of each of the first straight plates 1311. When the two first straight plates 1311 face each other, the limiting block 133 is pressed between the two first straight plates 1311. The limiting block 133 can be provided along the upper part of the first straight plates 1311. When the two first straight plates 1311 face each other, the limiting block 133 is pressed against the inner side of the opposite first straight plates 1311. The limiting block 133 can limit the complete fit of the two first straight plates 1311, thereby ensuring that the two arc-shaped plates 1312 face each other.

[0054] In a specific embodiment of the present invention, in order to facilitate the connection of the upper pressure plate 132, a groove box 134 is arranged along the upper portion of the first straight plate 1311 of one of the lower pressure plates 131, a cover plate 135 having a width greater than the width of the groove box 134 is arranged on the upper portion of the groove box 134, and a groove 136 is opened in the middle portion of the cover plate 135.

The opposite sides of the photovoltaic panel 3 are clamped and fixed firmly by the horizontal plates 1322 and the lower pressing plate 131. The longer notch 136 can adapt to the displacement of the panel 21 and the locking plate 22 when they expand and contract due to heat.

[0058] In a specific embodiment of the present invention, the length of the trapezoidal pressure plate 1321 is the same as the length of the trough box 134 , so that the length of the cross plate 1322 is the same as the length of the support plate 1315 , thereby stably clamping the photovoltaic panel 3 .
