This study is based on the design and overall structure of the building, taking the actual production situation as the starting point, and combining with the crane's operating scope and the principle of minimum cost, the graphic design scheme is determined. The design values of column spacing and span are 6m and 6m respectively. The floor plan of the workshop is about 7 × 6 meters. Wind columns are located at both ends of the workshop, and are scientifically set according to 9m column spacing standard.
