The invention concerns an apparatus (1) for building block systems including rectangular building blocks of concrete or similar material which are arranged to be attached to other building blocks using couples in rows to form a wall (7) whereby the couples are formed by extensions and depressions along the sides of the blocks adjacent to each other. One side of each building block has a number of openings that are shaped to accept pairwise coupling columns from building blocks coupled to each other in rows. |
