Support and lift the groove of 12b. Then, the trailer is moved with respect to the lifted assembly structure 10 so that the loading platform of the trailer is positioned below the assembly structure 10 . After that, the assembly structure 10 lifted by the lifting device is lowered and placed on the bed of the trailer. Thereby, the assembly structure 10 can be loaded on a trailer and the assembly structure 10 can be transported. Thus, in the assembly structure 10 of this embodiment, the upper frame 12 and the lower frame 14 are made of channel steel, and the grooves of each channel steel are arranged so as to face the outside of the assembly structure 10. Therefore, it can be easily lifted by a lifting device.

In addition, the assembly structure 10 of this embodiment can be vertically stacked with respect to other assembly structures 10 . For example, as shown in FIG. 8, the channel steel 12a of the upper frame 12 of one assembly structure 10 and the channel steel 14a of the lower frame 14 of the other assembly structure 10 are fastened with bolts 92 and nuts 94. By doing so, the assembly structure 10 on the upper side can be supported with respect to the assembly structure 10 on the lower side. That is, a plurality of assembly structures 10 can be arranged vertically.

Also, the assembly structure 10 of this embodiment can be horizontally connected to another assembly structure 10 . For example, as shown in FIG. 9, the channel steel 14a of the lower frame 14 of one assembly structure 10 and the channel steel 14a of the lower frame 14 of the other assembly structure 10 are connected in a state of being adjacent to each other.

Also, the number of studs 18 may be appropriately set according to the size of the assembly structure 10 (that is, the length of the channel steels 12a, 12b and the channel steels 14a, 14b, etc.).

In the above-described embodiment, the plurality of auxiliary members 30 connecting the upper frame 12 (channel steel 12a) and the lower frame 14 (channel steel 14a) may not be provided, and the assembly structure 10 The number of auxiliary members 30 may be appropriately set according to the size (that is, the length of channel steels 12a, 12b and channel steels 14a, 14b, etc.).

Also, in the embodiments described above, the support members 32, 34 may not be provided.

Further, in the above-described embodiment, the back plate 36 is joined to the stud 18, but instead of the back plate 36, for example, channel steel is used, and the stud 18 and the channel steel are connected by bolts. may be concluded. With such a configuration, the step of joining the studs 18 and the back plate 36 is not required when assembling the assembly structure 10 . That is, since the assembly of the assembly structure 10 does not require any welding technique, the assembly structure 10 can be assembled more easily.
