The steel platform usually includes a walkway plate for construction personnel to move and place automated equipment and a connecting rod assembly that supports the walkway plate, wherein the connecting rod assembly includes multiple rods and connecting plates between the rods. The connection strength is improved by welding the connecting plates between the two rods. However, since there is no pre-positioning structure in the rod, and the number of connecting plates is large and the volume is small, it is not easy to weld during welding, and it is easy to offset, thereby affecting the welding accuracy. In addition, the walkway plate is often fixed to the steel platform by simple bolts, buckles or welding. There is no pre-positioning structure for pre-positioning during installation. However, due to the large number of walkway plates, small offsets or errors will accumulate after full laying, resulting in larger offsets, making it impossible for some walkway plates to be installed in the preset hole positions.
