PROBLEM TO BE SOLVED: To provide a stacking block capable of attaining reduction in the cost required for constructing a retaining wall and the like and shortening its construction period and the like.SOLUTION: An inventive stacking block includes: a rectangular first wall part (1); a rectangular second wall part (2) formed to be opposed to the first wall part; fitting protrusions (41, 42) extendingly protruding outward from the inside of one side of the wall parts; and a connection part (3) connecting the first and second wall parts together while at least forming a fitting space in which the fitting protrusions can be externally inserted into the inside of any other side except the inside of one side. Preferably, the fitting protrusions consist of the first fitting protrusion (41) extending from the inner surface side of the first wall part, the second fitting protrusion (42) extending from the inner surface side of the second wall part, and an open groove part (43) extending in the direction of one side and formed between the fitting protrusions. The inventive stacking block has a large degree of freedom in stacking, enables a large number of stacking blocks to be stably stacked, and is excellent in workability. |
