PROBLEM TO BE SOLVED: To provide an articulated block which simplifies laying work, which can adapt to laying on a curved surface and a crimped surface, which is excellent in safety and workability by virtue of the absence of lift and burr, and which is inexpensive by virtue of the unnecessity of a high construction cost. SOLUTION: In this block 1, concave and convex hinge locking parts 1c and 1d, which enable horizontal connection and vertical fixation by using a skeleton shape composed of concave and convex parts 1a and 1b of an outline, are provided in an integrally formed manner. In a state wherein the plurality of blocks are laid, the fixability of a horizontal outline concave and convex joint and the vertical hinge locking parts 1c and 1d enables the prevention of the lift and the burr, the simplification of the laying work, and adaptation to the laying on the curved surface and the crimped surface.
