ABSTRACT:
A building block for dry wall construction has a body with front and rear faces, opposite end faces and top and bottom faces. One end face has a laterally projecting vertically extending rib with an arcuate outer surface, and the other end face has an arcuate recess to receive the rib of a laterally adjacent like vertically extending block in a manner permitting limited relative swivelling movement of two blocks about a vertical axis. One of the top and bottom faces has at least one projection, and the other of the top and bottom faces has a laterally extending groove to receive the at least one projection of a vertically adjacent like block in a manner to permit relative lateral adjustment of vertically adjacent blocks and prevent relative forward or rearward movement thereof.
