PROBLEM TO BE SOLVED: To provide connection blocks which has light weight, is high in strength, and can substitute for bricks and concrete blocks for kitchen garden, gardening, and the like.SOLUTION: Provided are connection blocks 1 high in strength, made of plastic and formed by injection molding, where fitting of a plurality of connection blocks is repeated in a manner that the fitting convex part of a first connection block 1 and a fitting concave part 1a of the next connection block 1 are engaged with each other. The fitting is repeated so as to form a block stacking body in which fitted blocks are stacked in a plurality of stages. In the fitted concave part, a beam is provided and is configured to, when another connection block 1 is connected to the block 1 with the beam, abut the fitting convex part 1a of the other connection block 1. By fitting and connecting a plurality of the blocks 1, a block stacking body is formed rearrangeably.COPYRIGHT: (C)2015,JPO&INPIT【課題】家庭菜園やガーディニング用の煉瓦やコンクリートブロックに代わる軽量で高強度な連結ブロックを提供する。【解決手段】射出成形によるプラスチック製の高強度の連結ブロックであって、一つ目の連結ブロック1の嵌合凹部と次の連結ブロック1の嵌合凸部1aとを係合するよう複数の連結ブロック1間で嵌合を繰り返し複数段に積み重ねたブロック積層体を形成する連結ブロック1であって、前記嵌合凹部内に梁を設けるとともに当該連結ブロック1に別の連結ブロック1を連結する際に当該梁が他方の連結ブロックの嵌合凸部1aに当接するようにする。複数個、嵌合連結することで積層体を形成して組み換え可能とする。【選択図】図1
