Abstract:
A concrete block stacking system for dry stacking of concrete reinforced walls comprising:a stretcher block having a pair of opposed front and rear panels, a top and bottom surface, and opposed first and second end wall surfaces;said bottom surface having a pair of co-planar, parallelly disposed laterally extending rectangular edge portions delineating a recess therebetween, said recess being formed and defined by upwardly converging surface portions of triangular cross-sectional configuration extending from said front and rear panels respectively and intersecting at a common central apex;said top surface having a generally flat central portion lying along and above a plane parallel to the plane of the top edges of said front and rear surfaces, said flat central portion being disposed intermediate a pair of laterally disposed parallelly extending rectangular edge portions the top surfaces of which intersect said front and rear panels and said flat central panel to form upwardly converging surfaces of truncated triangular cross-sectional configuration, an inside portion of said top surfaces being matingly abuttable to said upwardly converging bottom surface portions of a neighboring stretcher block in an adjacent upper stacked row;said first end wall surface having a first end wall recess with a planar portion disposed intermediate a pair of inwardly converging inwardly extending end wall surface segments, said planar portion having its outer surface disposed along a plane perpendicular to the plane of said top surface flat portion, said first end wall recess further being disposed intermediate a pair of co-planar, parallelly disposed laterally extending generally parallelepiped outer end wall surface segments each of which are disposed along a plane perpendicular to said top surface flat portion; andsaid second end wall surface having a central protrusion formed thereon, said protrusion being of a configuration matingly abuttable to and adapted to be accommodated within said first end wall recess.
