Furthermore, since the barrel structure in this case can also be completed by the assembly of the upper barrel and the lower barrel, or the assembly of the top plate and a plurality of barrel wall panels, the difficulty of making the barrel structure can be greatly reduced. It also facilitates the transportation and handling of related components. In particular, since the related components can be replaced and transformed for assembly, it is possible to replace the components of different sizes to assemble the required barrel structure according to the needs of the project, thereby providing the builder with more choices.

Through the detailed description of the preferred embodiments above, it is hoped that the features and spirit of the present invention can be described more clearly, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, the intention is to cover various modifications and equivalent arrangements within the scope of the claimed scope of the present invention.
