Reinforced concrete building blocks - contain channels on one side at predetermined distance from each end

摘要

Reinforced concrete building blocks for erecting retaining walls, noise insulating panels etc. contain two channels in one side of a depth equal to half the thickness of the block. These locate over e.g. metallic rods when placed on top of or next to one another. The channels are situated at a distance situated from each end of the block where L is the length of the block and K is a constant value for all the blocks in a particular construction or a multiple of the square root of 2.
