The quadrangular prism support 48 has four iron vertical pipes 48a extending in the vertical direction and iron connecting members 48b connecting adjacent vertical pipes 48a to each other, and is formed in a quadrangular prism shape. Further, the quadrangular columnar post 48 has a jack portion 49 at its lower portion in the vertical direction. A plate-like member 42 and a manual hoist 45 (see FIG. 6) can be provided on the upper end portion 48c of the quadrangular columnar column 48. As shown in FIG.

Instead of the vertical truss 40 (see FIGS. 2 and 15) of Embodiments 1 and 3, it is possible to use square columnar struts 48 that do not have such a truss structure. Further, since the quadrangular pillar-shaped support 48 has a jack portion 49 at its lower portion, it is possible to adjust the length of the square pillar-shaped pillar 48 in the longitudinal direction. In addition, the quadrangular columnar support 48 constitutes a columnar member. Other configurations are the same as those of the first or third embodiment.

In this way, since the columnar member is the square columnar support 48, the columnar member extending in the vertical direction can be made lightweight and easily.

Although the quadrangular column support 48 of Embodiment 4 has the iron vertical pipe 48a and the iron connecting member 48b, the material of the vertical pipe 48a and the connecting member 48b is not limited to iron. Other metal materials may be used as long as they have sufficient strength.

Further, in Embodiments 1 to 4, the horizontal curing net and the vertical curing net are used as the curing members, but other appropriate curing members may be used. For example, a known curing sheet may be used as the curing member. Further, in Embodiments 1 to 4, the horizontal protective net and the vertical protective net are formed as separate nets, but the horizontal protective net and the vertical protective net may be integrally formed as a net.
