Blocks for constructing low-rise ornamental wall and method

A pair of cast cementitious blocks for constructing a low-rise interconnected wall with a plurality of said blocks, said wall having a first course of said pairs of blocks placed side-by-side and a second course of said pairs of blocks stacked in side-by-side relation on said first course and offset relative to said first course,

• each block of said pair of blocks comprising a cast cementitious body having a bottom surface and an opposing top surface, a front face and an opposing back face, and two opposing sides that each define side faces between said front face and said back face;
• in a first block of said pair of blocks, said two opposing sides thereof diverge outwardly from said front face to said back face at an obtuse acute relative to said front face;
• and
• in a second block of said pair of blocks, said opposing sides thereof converge inwardly from said front face to said back face thereof at an acute angle relative to said front face, said angles of divergence and convergence of said side walls being substantially supplementary,
• whereby said pair of blocks, being positioned side-by-side, define a substantially straight line along the face of said pair of blocks;
• said top surface in each said block defines a dished, recessed cavity for filling with an adhesive and having an alignment point;
• each said block further defines a bore extending therethrough and open at said top surface and said bottom surface, said bore defining a longitudinal axis therein, said alignment point of said dished recessed cavity and said longitudinal axis being substantially equally spaced from a front edge of said top surface and substantially equally spaced laterally from a line bisecting said front face,
• whereby said longitudinal axis of said bores of said blocks positioned in said second course substantially align with respective alignment points of said recessed cavities of said blocks in said first course,
• said bore for receiving an adhesive which fills said aligned dished recessed cavity and at least a portion of said bore, said adhesive being curable to define rivets in situ interconnecting said blocks in said second course and said blocks in said first course.

A low-rise decorative wall for landscape ornamentation, comprising:

• a first tier of blocks placed side-by-side whereby at least each side edge of a front face of each block contacts a side edge of said adjacent block;
• a second tier of blocks placed side-by-side on an upper surface of said first tier of blocks, said blocks in said second tier offset relative to said blocks in said first tier whereby said side edges of said blocks in said second tier are aligned medial said side edges of a pair of blocks in said first tier;
• each of said blocks defining a bottom surface and an opposing top surface, a front face and an opposing back face, and two opposing sides that each define side faces between said front face and said back face;
• said top surface defining a dished recessed cavity for receiving an adhesive and having an alignment point;
• said block further defining a bore extending therethrough and open at said top surface and said bottom surface, said bore defining a longitudinal axis therein;
• and
• said alignment point of said recessed cavity and said longitudinal axis being substantially equally spaced from a front edge of said top surface and substantially equally spaced laterally from a substantially perpendicular line bisecting said front face,
• whereby said longitudinal axis of said bores of said blocks positioned in said second course substantially align with respective alignment points of said recessed cavities of said blocks in said first course,
• said bore for receiving an adhesive which fills said aligned recessed cavity and at least a portion of said bore, said adhesive being curable to define rivets in situ interconnecting said blocks in said second course and said blocks in said first course.

A low-rise decorative wall for landscape ornamentation assembled from a plurality of pairs of blocks aligned side-by-side in tiers to a predetermined height for the wall, comprising:

• a first tier of pairs of blocks placed side-by-side whereby at least each side edge of a front face of each block contacts a side edge of said adjacent block;
• a second tier of pairs of blocks placed side-by-side on an upper surface of said first tier of blocks, said blocks in said second tier offset relative to said blocks in said first tier whereby said side edges of said blocks in said second tier are aligned medial said side edges of said blocks in said vertically lower first tier;
• each of said blocks in said pair of blocks defining a body having a bottom surface and an opposing top surface, a front face and an opposing back face, and two opposing sides that each define side faces between said front face and said back face, said top surface defines a dished recessed cavity for receiving an adhesive and having an alignment point, said block further defines a bore extending therethrough and open at said top surface and said bottom surface, said bore defining a longitudinal axis therein, and said alignment point of said recessed cavity and said longitudinal axis being substantially equally spaced from a front edge of said top surface and substantially equally spaced laterally from a line bisecting said front face,
• whereby said longitudinal axis of said bores of said blocks positioned in said second tier substantially align with respective alignment points of said recessed cavities of said blocks in said first tier,
• said bore for receiving the adhesive which fills said aligned recessed cavity and at least a portion of said bore, said adhesive being curable to define rivets in situ interconnecting said blocks in said second tier and said blocks in said first tier;
• one block of said pair of blocks having opposing sides that diverge outwardly from said front face to said back face at an obtuse angle relative to said front face;
• another block of said pair of blocks having opposing sides that converge inwardly from said front face to said back face at an acute angle relative to said front face;
• and
• said angles of divergence and convergence of said side walls being substantially supplementary,
• whereby said pairs of blocks, being positioned side-by-side in said courses of blocks to form a low-rise ornamental wall, define a substantially planar surface for the wall.

A method of assembling a low-rise ornamental wall from a plurality of blocks, comprising the steps of:

• (a) placing a plurality of blocks side-by-side in a course of said blocks to define a first tier of a wall of said blocks, each of said blocks defining a bottom surface and an opposing top surface, a front face and an opposing back face, and two opposing sides that each define side faces between said front face and said back face, said top surface defining a dished recessed cavity for receiving an adhesive and having an alignment point, and each of said blocks further defining a bore extending therethrough and open at said top surface and said bottom surface, said bore defining a longitudinal axis therein, said alignment point of said recessed cavity and said longitudinal axis being substantially equally spaced from a front edge of said top surface and substantially equally spaced laterally from a line bisecting said front face;
• (b) placing a plurality of said blocks side-by-side in a second course of said blocks to define a second tier in said wall of said blocks, said second tier of blocks being off-set substantially one-half width of a block, whereby said longitudinal axis of said bores of said blocks positioned in said second tier substantially align with respective alignment points of said recessed cavities of said blocks in said first tier;
• and
• (c) filling said aligned recessed cavities of said blocks in said first tier and at least a portion of said bores in said blocks in said second tier with adhesive, whereby said blocks in said first and second tiers are joined together, said adhesive being curable to define rivets in situ interconnecting said blocks in said first and second tiers.
