PROBLEM TO BE SOLVED: To provide a block connecter capable of reliably connecting large-sized concrete blocks when they are laid for bank protection. SOLUTION: This is a block connector 26 which is inserted through overlapped ends 7a protruding from the side walls of adjacent blocks 2 to be connected together when they are laid. The block connecter 26 is nearly T-shaped, consisting of a head 26a and a stem 26b to be inserted through the overlapped ends. Engaging protrusions 26c are formed on the stem 26b in order to engage with one of the overlapped connecting ends of blocks. COPYRIGHT: (C)2005,JPO&NCIPI
