Unit for block walls and walls incorporating the unit

Abstract

A unit for block walls and block walls assembled from said units. The units have top and bottom surfaces joined by spaced-apart planar abutment surfaces that form equal dihedral angles such that when two units are abutted at their base surfaces, they form in side view a hexagonal array that is self aligning and mutually supporting. Fractional units can be provided at ends of the wall which carry only a single abutment surface.

1 . A unit for assembly to form a mortarless block wall, said unit comprises a solid body having for its outer surfaces a base surface, two side surfaces, a top surface and two abutment surfaces, said base surface and top surface being parallel to one another said side surfaces being parallel to one another, the abutment surfaces forming equal dihedral angles with the base surface and with the top surface, whereby when stacked to form a column, with base surfaces in contiguity with one another, the view of the pair from the side is hexagonal. 
   
   
       2 . A unit according to  claim 1  in which said dihedral angles between the base surface and the abutment surface is 60 degrees. 
   
   
       3 . A unit according to  claim 1  in which said side view is a regular hexagon. 
   
   
       4 . A fractional unit for completion of a wall comprising a plurality of columns according to  claim 1 , in which said fractional unit has only one abutment surface, the other end of said fractional unit being planar and normal to the base surface, the top surface, and the side surface. 
   
   
       5 . A unit according to  claim 1  in which a passage extends between the top surface and base surface to pass a reinforcement and also contain cement to reinforce a column of said units with the passages aligned. 
   
   
       6 . A mortarless wall comprising a plurality of vertical columns of units according to  claim 1 , with adjacent units alternately disposed, with pairs of abutting top surfaces and pairs of abutting base surfaces, and with abutment surfaces of each column abutting abutment surfaces of its neighboring columns, 
   
   
       7 . A mortarless wall according to  claim 6  in which a stack of fractional units abut an end one of said stacks of units to finish the end of the wall. 
   
   
       8 . In combination a mortarless wall according to  claim 6  and a base support, said base support having upright studs to align passages of respective in each vertical columns.
