Cube-shaped concrete building-slab, for gardens - is of trapezoid cross-section, and prismatic, parallel-edged exterior, and has gripping-strips or ridges (OE150976)

摘要

The garden building-slab has one outside surface which is entirely enclosed by grip-strips (5, 6) and two outer surfaces with strips on three sides. Alternatively, two surfaces have grip-ridges on three edges (61, 62, 63) and one surface has grip-edges on two edges. A beaded ridge (7) can frame all sides of the sides (3) and the base (2). Surfaces (4, 4') have no grip-ridges. The slab is easy to handle and eliminates any possible damage to fingers of operator.
