Structural member used for rainwater storage laminated structure
The present invention is a structural member for constructing a rainwater storage laminated structure by vertically stacking the structural members while crossing the structural members at right angles in a water storage tank provided under the ground, the structural member enabling accurate and stable stacking to thereby obtain a water storage laminated structure with a small number of tiers but a large rainwater storage capacity. A structural member (1) has a structure in which hollow truncated quadrangular pyramids (2) each formed by providing an inclined surrounding wall plate (2b) along four edges of a rectangular top wall plate (2a) are arranged side by side longitudinally and laterally with the lower ends thereof coupled to each other via a bottom plate portion (3a) having a constant width, protruding portions (4, 4) are provided to protrude on both ends of the top wall plate (2a) to support the lower ends of both-side inclined wall plate portions of the truncated quadrangular pyramid (2) of the upper-side structural member (1) on the top wall plate (2a) of the lower-side structural member (1), the lower ends are locked to the opposite inner surfaces of the lower ends of the protruding portions (4, 4) to catch a load from above, and further an engagement recessed portion (5) that is put on the protruding portions (4, 4) of the structural member (1) disposed on the lower side to thereby prevent the structural member (1) from randomly moving longitudinally and laterally is provided in the bottom plate portion (3a).
