摘要

The wall has a set of rectangular or square shaped juxtaposed identical units including a groove on its longitudinal and transversal sides. The groove defines a lower horizontal groove (6) and an upper horizontal groove (7) which form a longitudinal housing for receiving a blocking slat (8) and form another housing on their lateral sides for receiving a vertical wedged keying part.
