The structural rod 104 includes an upper side plate 105, an outer side plate 106 and a lower side plate 107 which are connected vertically in sequence. The upper side plate 105 is located directly above the lower side plate 107. The two ends of the structural rod 104 include end plates 108, which are respectively vertically connected to the upper side plate 105, the outer side plate 106 and the lower side plate 107. The end plate 108 is also vertically connected to a mounting plate 109, the upper side of the mounting plate 109 is vertically connected to the upper side plate 105, and the lower side of the mounting plate 109 is vertically connected to the lower side plate 107. The two ends of the upper side plate 105, the two ends of the lower side plate 107, the end plate 108 and the mounting plate 109 are respectively provided with a plurality of screw holes 110 for screws to pass through. A reinforcing rod 111 is installed in the structural rod 104, and a reinforcing grid plate 202 is provided on the inner side of the sheet metal unit 201.
