Patent US 4,959,937

Architectural glass block walls or panels are constructed by assembling a plurality of blocks using connectors which provide securement and uniform spacing of the blocks in a width and height direction. Each connector comprises a pair of rigid, elongated members each having a pair of spaced, planar opposite surfaces, and a laterally centered longitudinal groove in each surface. Each member is joined to the other member and each connector is disposed at an intersection of the corners of and in abutment with a plurality of blocks with each longitudinal groove engaging a ridge which extends around the circumference of each block. The connectors can be secured to the blocks with an adhesive compound, e.g., a curable silicone caulking composition, and the spaces between the blocks can be filled with mortar, grout or caulking material to seal the wall or panel and embed and conceal the connectors in the mortar. The glass blocks can be laid up in either the "regular stack-up" configuration in which glass blocks are usually laid up in straight, horizontal courses and vertical tiers; or in an "overlapping" configuration in which glass blocks are laid overlapping as in the case of bricks.
