<P>PROBLEM TO BE SOLVED: To construct such a wall as to transfer an averaged load to a water storage space forming block. <P>SOLUTION: A wall unit for water storage tank comprises an outer frame 11 constituted of a horizontal member 12 along both upper and lower end faces in a unit outer form in a rectangular parallelepiped shape and a vertical member 13 along both end faces in a width direction, the unit outer form having a unit width (x) corresponding to one side of a horizontal structure part of a water storage space forming block used for an underground water storage tank, a unit height (z) corresponding to a double height dimension of the water storage space forming block and predetermined unit thickness (y). An outer flange part 14 and an inner flange part 15 along one and another faces of the unit outer form in a direction of the unit thickness (y) are disposed alternately in a direction of the unit width (z) and connected via connecting plate ribs 16 in the direction of the unit thickness (y), and the connected flange parts are then connected inside of the outer frame 11. Vertical plate ribs 17 and horizontal plate ribs 18 are provided on an outer surface of the inner flange part 15, through-holes 32 are provided in the flange parts 14, 15, thereby forming a wall unit 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
