Abstract
An assembly of at least two parts of blocks made of lightweight concrete, wood, or rock separated by a channel void or fi lied with an insulating substance. Channels provide a sound barrier and insulation. Attachment of the blocks can be made by means of angular steel pins fixing blocks two by two, by means of adhesive fiber glass wrapping the blocks, by means of adhesive construction glue, or by means of crossed tie resisting to shear forces. Central channels in the blocks are dug to pass a metal rod to strengthen the whole assembly of blocks; a central passage pierced in a top face of a central block wherein a metal rod is inserted and continues through an end groove of an upper and a lower block. Or, channels are dug all along the periphery of the block, and horizontal and a vertical rods are affixed against the channel.
