In this embodiment, adjacent aluminum alloy frames and aluminum alloy middle frames are corner-jointed and then fixed by self-tapping screws; in a parallelogram frame 5, the aluminum alloy middle frames are fixed to each other and form multiple equilateral triangle frames, the number of triangular metal plates 4 is equal to the number of equilateral triangle frames, and the triangular metal plates 4 are installed and fixed on the equilateral triangle frame formed by the aluminum alloy middle frame.

The triangular metal plate 4 is fixed to an equilateral triangle frame formed by fixing the aluminum alloy middle frame to each other through the connecting angle codes 6. In order to facilitate the adjustment of the position of the triangular metal plate 4, vertical long holes are opened on the connecting angle codes 6. The vertical long holes are used for the triangular metal plate 4 to move up and down, thereby realizing the vertical adjustment of the position of the triangular metal plate 4. When the triangular metal plate 4 is adjusted to the appropriate position, the commonly used angle code gaskets and bolts in the field can be used to lock it, thereby improving the flatness of the triangular metal plate 4.
