Abstract:
The invention relates to prefabricated building blocks, preferably of right prism or prism-like shape with tetragonal base and top. The invention is characterised in that each building block has shutter prism (1) of constant height (1 m) and frontal prism (2) of constant height (2 m) exceeding the height of the shutter prism (1), and there is a salient flange (3) formed on the top surface (21) of the frontal prism (2) of width (31) determined by the position, shape and area of the bottom surface (12) of the shutter prism (1) and of size equal to the height (1 m) of the shutter prism (1), established between the boundary of the top surface (21) of the frontal prism (2) and the boundary of bottom surface (12) of the shutter prism (1).
