Polygonal multi-elements concrete paving stone - with three sides of dodecagon on each outer side

摘要

The paving block, which is polygonally defined in plan and has vertical lateral surfaces, interlocking with other blocks is assembled from two or more individually elements, one behind the other of the same shape, with a promontory projects from the polygonal face on top surrounded by the polygonal shape of the lateral surfaces. On each side of the block the outside defining polygon faces consist of three sides of a dodecagon surrounding the protruding facing surface. The interconnecting part providing a link to the adjacent individual element in the block is in the form of faces running parallel to the block's longitudinal axis, and is at least two-thirds as wide as the overall width. The promontory may circularly defined. This is easily manipulated and less fragile and aesthetically pleasing.
