Structural member used in rainwater storage laminated structure
Provided is a structural member for constructing a rainwater storage laminated structure by vertically stacking the structural members in a water storage tank provided beneath the ground while crossing the structural members at right angles, the structural member capable of exhibiting strong compressive strength without being deformed by loads from above and below. A structural member (1) is formed by longitudinally and laterally arranging, on a bottom plate (2), hollow truncated quadrangular pyramids (3) formed by providing front, back, right and left inclined wall plate parts (3b-3d) downward from four edges of a rectangular top plate (3a) with the lower ends thereof open downward from the lower surface of the bottom plate (2), and configured such that a V-shaped middle groove part (5) is formed so as to divide the top plate part (3a) in two in the middle of each of the hollow truncated quadrangular pyramids (3), the groove bottom lower surface of the middle groove part (5) is supported on a pair of hollow protruding parts (4, 4) provided to protrude on the top plate part (3a) of the lower-side structural member (1), and engagement recessed parts (7, 7) formed in lower end middle sections of both side inclined wall plate parts (3c, 3c) are put on both ends of the top plate part (3a) of the lower-side structural member (1).
