Detailed Description

The following description of the embodiments of the present invention will explain the embodiments of the present invention in further detail by referring to the accompanying drawings.

As shown in fig. 1 to 12, the assembled lattice column structure convenient to mount and dismount comprises a group of angle irons 2, a group of connecting batten plates 3 and connecting flange plates, wherein the connecting flange plates are arranged at the end parts of the group of angle irons, the connecting batten plates are connected with adjacent angle irons, bolt connecting holes 6 for butting adjacent lattice columns are formed in the connecting flange plates, and the connecting flange plates penetrate through the bolt connecting holes in the two butted connecting flange plates to be connected through connecting bolts 7.

As shown in fig. 1, the two end parts of the angle iron are connected with connecting flange plates, namely, the upper flange plate 1 is welded at the upper end of the corresponding angle iron, and the lower flange plate 5 is welded at the lower end of the corresponding angle iron; as shown in fig. 2, a connecting flange is connected to one end of the angle iron, that is, the flange is welded only to the upper end of the angle iron.

The connecting flange plate is a circular disc, a square hole is formed in the center of the circular disc, and the end of each angle iron is arranged corresponding to the corner of the square hole; one side of connecting the batten plate is welded with the outside of the angle iron corresponding to one side, the other side of connecting the batten plate is welded with the outside of the angle iron corresponding to the other side, a supporting structure is formed by welding a group of angle irons and a group of connecting batten plates, and the supporting structure is a main stress part.
