Referring to fig. 3, the wire hanging plate 130 is provided with a mounting hole 131 and a wire hanging hole 132. The attachment plate 130 is fixedly connected to the first flange 1111 and the second flange 1211 through the mounting holes 131, and when assembled, the first sub-beam 110, the attachment plate 130 and the second sub-beam 120 are fixedly connected to each other through the first through hole 11111 of the first flange 1111, the mounting holes 131 of the attachment plate 130 and the second through holes 12111 of the second flange 1211 in sequence by using bolts or the like. The hanging wire hole 132 is used for hanging a wire, and particularly, the hanging wire hole 132 is directly connected with a hanging wire fitting for hanging the wire. In other embodiments, the two opposite surfaces of the wire hanging plate 130 may be welded to the disk surface of the first flange 1111 and the disk surface of the second flange 1211.
