Claims

[Scope of Claim for Utility Model Registration] (1) A cross-shaped concrete block when viewed from the front, with a concrete frame integrally provided behind the peripheral edge of the back of the block-shaped concrete block body, and the outside of the frame. A cross-shaped concrete block for a retaining wall, characterized in that its peripheral surfaces are formed into a fitting structure that allows them to be joined to each other in the vertical direction. (2) The fitting structure of the frame consists of a plurality of plate-like fitting frames having the same external shape as the concrete block main body, which are shifted in an appropriate diagonal direction and overlapped. Cross-shaped concrete blocks for retaining walls as described in item ).
