Abstract: Set of angular building elements for building visual protection, acoustic protection or detonation protection walls which can contain plants, for plant tubs, slope supporting elements, supporting pillars as well as surrounds for plots, paths and flower-beds. Molded bricks and elements, having a mainly equal-sided angular cross-section with any internal angle, mainly of 90 and 60 degrees, and equal-sided side ends, are assembled by masonry techniques with offset cross-joints into free-standing or escarped supports and walls with plants. Various walls and supports which can be statically load-bearing can thus be constructed without liquid by means of a single angular element and the hollow chambers can be reinforced and grouted with mortar. Several solutions are available for dowelling the horizontal joints, such as edge molding and connecting pins.
