Abstract

1,232,530. Building blocks. GROUTLOCK CORP. 18 Sept., 1969 [27 Sept., 1968], No. 46112/69. Heading E1B. A ribbed and grooved concrete block 10 has a central aperture 22 with sideways extensions 23 connecting the upper and lower grooves 15 and 16 which also intersect end grooves 21 so that a continuous skeleton of mortar can be introduced after the blocks have been built up into a wall. Further through air apertures 24 are formed but are not connected with the motor complex. Blocks of half thickness e.g. 4" having only one rib are also disclosed and are used with the full blocks to form 12" walls. Modified blocks for corners, wall junctions and door and window openings are also included. The half thickness blocks have diamond section apertures. Angle section wire ties may be used to reinforce the corners of walls.
