Abstract
A dovetailed building block includes a block body having a regular polygonal shape having side surfaces in which dovetailed recesses and dovetailed projections are alternately formed. To join two building blocks in a transverse direction, one dovetailed projection of one building block is received in and retained by one dovetailed recess of the other building block. The building block has a simple structure and allows for assembly in a curved form to present unique three-dimensional configurations with versatile variability. Each or one of the dovetailed projections of the building block has upper and lower ends that respectively form upper and lower inclination facets so that when two building blocks are joined in a longitudinal direction, the upper and lower inclination facets of the two blocks are positioned against each other. A positioning point is formed in the dovetailed recess by the upper inclination facet to ensure firm and stable connection.
