Connecting Beam for Solar Photoelectric Supporting Frame

A connecting beam for a solar photoelectric supporting frame, characterized in that the connecting beam is an elongated object made of rigid material and comprises:

• a bottom plate portion including a lower surface and an upper surface;
• a first side plate portion disposed on a side of the bottom plate portion, with the first side plate portion being obliquely disposed relative to the bottom plate portion and including a first inner surface at a side thereof adjacent to the upper surface of the bottom plate portion, with an angle between the first inner surface and the upper surface of the bottom plate portion being greater than 90 degrees;
• and with a reflective face capable of reflecting light being disposed on the first inner surface;
• a second side plate portion disposed on another side of the bottom plate portion and opposite to the first side plate portion, with the second side plate portion having a height smaller than the first side plate portion, being obliquely disposed relative to the bottom plate portion, and including a second inner surface at a side thereof adjacent to the upper surface of the bottom plate portion, with an angle between the second inner surface and the upper surface of the bottom plate portion being greater than 90 degrees, with a groove formed between the first side plate portion, the second side plate portion, and the bottom plate portion, and with a spacing between upper ends of the first side plate portion and the second side plate portion being greater than a spacing between lower ends of the first side plate portion and the second side plate portion;
• a first upper plate portion including opposite first and second sides, with the first side connected to a top end of the first side plate portion, with a height of the second side being lower than the first side;
• and a second upper plate portion including opposite third and fourth sides, with the third side connected to a top end of the second side plate portion, with a height of the fourth side being higher than the third side.
