To provide a novel unit member constituted such that an operation to reinforce the unit member in a longitudinal direction is performed extremely easily and stably and extremely rational reinforcement is achieved.
There is provided a unit member constituted such that inner hollow bodies formed in a truncated conic shape are provided successively in an outer hollow body. A necessary number of first projections for stable support are projected on inner wall of upper end parts of the outer hollow part and a necessary number of second projections for stable support are projected on inner walls of lower end parts of the inner hollow body 2. Both of or one of a reinforcing cylinder body between opposed upper and lower first projections for stable support and a reinforcing rod-shaped body between opposed second projections for stable support is erected and supported.
