[0036] The paving grid is arranged in a horizontal and vertical staggered manner, the unit cell is a rectangle, and the stand column 1 is arranged in a horizontal and vertical staggered dot matrix. The load-bearing frame 2 needs to select a rectangular profile structure according to the shape of the unit cell. Similarly, the paving grid can also select other arrangement forms, and the shape of the load-bearing frame 2 is adjusted according to the unit cell.
