The interlocked building blocks, which normally require no mortar, have undercut grooves around their face edges, forming dove-tail-sectioned grooves at all the joints between adjacent blocks in a wall, which may be used to receive and hold sealing material for the joints, as well as to provide suitable support means for fixing attachment hooks or clips to the wall.

A wall construction of concrete blocks assembled without a binder therebetween and comprising a plurality of linear wall segments each comprising a double layer of blocks with the blocks in one layer overlapping the blocks in the other layer both horizontally and vertically, said blocks having identical horizontal sections with the inner faces of blocks in one layer having alternate and equal vertically co-extensive dove-tail grooves and ridges slidably interlocked with similar vertical coextensive dove-tail grooves and ridges in the inner faces of the blocks in the other layer, a corner wall segment comprising corner blocks having a plurality of angularly extending block portions joined to the linear wall segments, the corner block portions each having an identical half groove and half ridge interlocked in a running fit with the inner faces of end blocks of the linear wall segments, two spaced linear wall segments having a beam supported between them at points normally provided for a block in each of said wall segments, said beam having end faces formed like the interlocking inner faces of the blocks which they replace at their points of support in the respective wall segments, the dove-tail grooves and ridges on said blocks having planar faces which are positioned in face-to-face relationship when interlocked to define a close yet free fit without any noticeable play between interlocked blocks so that the wall is assembled without a binding agent between blocks, each block and beam end in said wall construction having a peripheral undercut groove extending completely around its face edges, the edge grooves of adjacent blocks forming undercut double groove channels along the joints, holding non-adhesive resilient packing strips for sealing without binding said joints and providing some frictional sliding movement between load-bearing surfaces of the blocks limited by the lateral clearances between their interlocking faces.
