The box panel unit 1 has evenly distributed openings 6 to facilitate the insertion of steel pipes 15. At the same time, some openings 6 are provided with flat ribs 10 with open centers to enhance the support force of adjacent box panel units 1 when splicing them up and down, and to ensure the stability of the support.

[0058] The panel units 1 can be assembled vertically via the mating interface 5 and the mating joint 4, which engage with the panel groove 9 and the elastic protrusion 7. The square upper forehead 2 and the square lower forehead 3 are the same size, ensuring a tight fit and preventing rotation after assembly. The small shaft 8 and shaft hole 14 on the upper and lower foreheads facilitate snap-fit ​​during assembly, preventing separation.
