高所作業員を使用するべきである。However, in this rainwater storage tank, since the pedestal 52 at the upper end of the support plate portion 53 has an extremely narrow width, a normal worker cannot use it as a scaffold when assembling and constructing each component. Have difficulty. When the cradle 52 is forcibly used as a scaffold, there is a high risk of slipping and dropping, and since the height of the support plate portion 53 is 3 to 4 m, the impact at the time of falling is large. Therefore, from the viewpoint of preventing work-related accidents, a dedicated scaffold should be installed separately or a skilled aerial worker should be used.

重量も増加する。In addition, the main body block having the inverted T-shaped vertical section and the peripheral block having the L-shaped vertical section are shown in FIG.
When it is placed sideways as shown in FIG. 1, the support plate portion 53 is not horizontal and the whole is tilted, so that regular stacking cannot be performed, and convenience during transportation and storage is poor. Further, since such a cross-sectional shape is structurally weak, it is necessary to increase the number of reinforcing bars or increase the plate thickness to compensate for it, which increases the manufacturing cost and the product weight.

However, with respect to the horizontal force in the left-right direction, the pedestal 52 itself has an extremely narrow width in the left-right direction, and when the horizontal force in the left-right direction is applied, it does not exhibit high rigidity and proof stress. There is no room to consider the part of the table 52 as a horizontal beam. In addition, since the main body block 50, 50 is arranged separately in the left-right direction, the pedestal 52 is isolated in the same direction,
Sufficient rigidity cannot be obtained for horizontal force in the left-right direction.
Further, although the rigidity is increased to some extent by disposing the intermediate upper surface plate 58 between the receiving bases 52, 52, since the width of the receiving base 52 is narrow, it is difficult to join the intermediate upper surface plate 58 rigidly, which is also sufficient. Rigidity and horizontal yield strength cannot be expected.
