CONCRETE BLOCK AND THE CONNECTING CONSTRUCTION BETWEEN CONCRETE BLOCKS

摘要

PROBLEM TO BE SOLVED: To provide a concrete block which does not require any working space for connecting to another adjacent concrete block between the concrete block and an excavated gutter in which another neighboring concrete block is to be laid. SOLUTION: A concrete block 1 is arranged laterally; a connecting source 3 faces the connecting surface 3 of other neighboring concrete block 2 and is connected to the concrete block 2 through a connecting body 4. Also, the concrete block 1 is opened upward and equipped with a recessed portion 6 communicating with the connecting surface 3; the recessed portion 6 is opened upward of the other concrete block 2 and is set to communicate with the recessed portion 6 passing to the connecting surface and forms a communicating recessed portion 8. The connecting body 4 is inserted from the above to the communicating recessed portion 8 and is housed in the communicating recessed portion 8.
