Form block to build a slope has hexagonal middle section, hexagonal joined-on parts which on every second side form a common hexagonal side and whose positioning angle, normally 120degrees, can be varied for uneven ground

摘要

Form block has a basic shape with a hexagonal middle section (1) and three hexagonal joined-on parts (2) which on every second hexagonal side of the middle section form a common hexagonal side (3) when put together. From this hexagonal side extend opposite-lying side flanks (4) of the respective add-on parts, two of which enclose a 120[deg] angle of hexagonal sides(5,6). To lay form blocks on uneven ground, the opposite-facing side flanks of the joined-on parts are placed symmetrically next to one another against a regular hexagon (7) at a pre-determined angle (alpha ) which represents a decrease in the area of the hexagon relative to the middle axis (8) of the middle section.
