- 地面を掘削することによって形成した貯水槽内に縦横に並設すると共に上下方向に直角に交差させながら積層することによって雨水貯留積層構造体を構築するための構造部材であって、平面四角形状の底板に下端がこの底板を貫通して下方に向かって全面的に開口している一定高さの四角錐台を前後左右に並設してなり、これらの四角錐台は、長方形状の天板部と、この天板部の四方縁辺から下方に末広がり状に延び、且つ、下端が上記底板に一体に連結している四方傾斜壁板部と、上記天板部における中央部に天板部の長さ方向に一定の間隔を存して突設している一対の中空突起部と、この中空突起部の対向面間の天板部の中央から下方に向かってV字状に窪ませて形成されている中央溝部とを有し、構造部材を直角に交差させながら上下方向に積層した際に、上側の構造部材の四角錐台における上記中央溝部の底部を下側の構造部材の四角錐台における天板部に突設した中空突起部に支持させると共に、上側の構造部材の四角錐台における両側の傾斜壁板部の下端を天板部の長さ方向の両端部上面に支持させるように構成していることを特徴とする雨水貯留積層構造体に用いる構造部材。
- 四角錐台における天板部の長辺側から下方に延びている両側傾斜壁板部の下端中央部と、この両側傾斜壁板部の下端に一体に連結している底板部に、下側に配する構造部材の四角錐台の天板部における両端部に被せて該両端部に係合させる係合凹部と、この係合凹部と同一断面形状でもって上方に向かって膨出した凹み底板部をそれぞれ形成していることを特徴とする請求項1に記載の雨水貯留積層構造体に用いる構造部材。
- 四角錐台の天板部における長辺側から下方に延びる両側傾斜壁板部に、数条の補強溝を四角錐台の全高に亘って形成していることを特徴とする請求項1に記載の雨水貯留積層構造体に用いる構造部材。
- 四角錐台の天板部に突設している一対の中空突起部における対向面と反対側の面の天板部と連なる下端に、天板部の幅方向に長い補強リブを下方に向かって突設していることを特徴とする請求項1又は請求項3に記載の雨水貯留積層構造体に用いる構造部材。
- 四角錐台における天板部と中央溝部の溝底部、及び隣接する四角錐台の下端縁間を連結している底板部とに上下面間に亘って貫通した通水孔を形成していることを特徴とする請求項1又は請求項2に記載の雨水貯留積層構造体に用いる構造部材。
- 底板の四方縁辺に一定高さを有する周枠を一体に設けていることを特徴とする請求項1に記載の雨水貯留積層構造体に用いる構造部材。
