Zusammenfassung:PROBLEM TO BE SOLVED: To provide a block connecting structure and block removal method with which it is possible to operate a connecting part on another side from either a right or left side wall part which comprises a block front side or rear side for the connecting part between precast concrete blocks.SOLUTION: In a connecting structure having a concrete block 1 extended in the longer direction, a connecting plate is arranged such that it straddles a left and right vertical part of a connecting part. The concrete blocks 1 are connected together by the connecting plate, and bolt insertion holes are provided on both ends of the connecting plate arranged such that it straddles between the concrete blocks 1. Fastening bolts are inserted into the insertion holes from the connecting plate positioned on either the right or left side wall part to the other side connecting plate, and a screwing part is integrally formed on the rear surface side of the bolt insertion hole on the other side connecting plate. The tip of the fastening bolt inserted from one side to the other side is fastened by the screwing part. A base end part, which is the fastening bolt insertion side, is fastened with a detachable screwing part.SELECTED DRAWING: Figure 1 【課題】プレキャストコンクリートブロック相互の連結部においてブロックの前面側或いは背面側となる左右側壁部のいずれか一方側から他方側の連結部を操作することのできるブロックの連結構造及ブロックの撤去方法を提供する。【解決手段】コンクリートブロック1を長手方向に延設させる連結構造において、連結部の左右垂直部に跨って連結プレートを配置し、連結プレートによりコンクリートブロック1相互を連結し、コンクリートブロック1間に跨って配置された連結プレートの両端部にボルト挿通孔を設け、左右側壁部のいずれか一方側に位置させた連結プレートから他方側の連結プレートへ向けて貫通孔を貫通させて締め付けボルトを挿通し、他方側の連結プレートはボルト挿通孔の表面側に螺合部を一体形成し、一方側から他方側へ挿入した締め付けボルトの先端部を螺合部で固定し、締め付けボルトの挿入側となる基端部は着脱自在の螺合部により固定する。【選択図】図1
