Preformed concrete brick for garden walls has in elevation laying surfaces and support surfaces for modular height and modular length respectively, with elevation reduced by at least two right-angled triangles

摘要

The preformed concrete brick (1) for garden walls is in rectangular ashlar form with modular height, width and length, and in elevation has laying surfaces (4) and support surfaces (5) for the modular height (2) and modular length (3) respectively. The elevation is reduced by at least two right-angled triangles (6), the sides of which lie on two adjacent elevation sides (7) in a way which the right-angled triangles do not reduce the laying surfaces or support surfaces.
