PROBLEM TO BE SOLVED: To provide a connected-type block that enables a structure in linear and curved layouts to be easily constructed without use of cement and an adhesive, in a flower bed frame, a partition and the like.SOLUTION: A block, in which connecting holes 20 are made in the centers of bottom and top surfaces of a regular quadrangular prism 30 with a square bottom surface, serves as one unit. In an octagonal prism-shaped block 10, both ends of a long side of a rectangular parallelepiped, in which the plurality of these units are serially arranged in such a manner that the hole-made surfaces are directed in the same direction, assume a shape formed by halving a regular octagon. A construction material for a flower bed frame, a partition and the like in linear and curved layouts is provided by a connected-type block for being connected by an inserting connection rod for being engaged with the connecting hole. |
