Claim 1
Independent Claim
274 words
A reinforced brick assembly comprising: a plurality of brick units; said brick units being stacked in a horizontal and a vertical dimension to form a brick panel; mortar between adjacent ones of said brick units in said brick panel; a plurality of holes in said brick units; at least one of said plurality of holes in at least some of said brick units being aligned with a hole in a vertically adjacent brick unit; the aligned holes being aligned through at least said vertical dimension of said brick panel; a vertical steel bar passing in the vertical dimension completely through all of said aligned holes; mortar in said aligned holes surrounding said vertical steel bar; a first support plate at a bottom of said brick panel; a second support plate at a top of said brick panel; a first end of said vertical steel bar passing through said first support plate and a second end of said vertical steel bar passing through said second support plate; means on said first and second ends outside said first and second support plates for prestressing said vertical steel bar in said mortar; at least one horizontal steel bar in said mortar between at least one vertically adjacent pair of horizontal rows of said brick units; a support means in said mortar between first and second vertically adjacent brick units; an upper half leg on said support means passing vertically upward into a hole in said first brick unit; a lower half leg on said support means passing vertically downward into a hole in said second; and mortar in said holes surrounding said upper and lower half legs.
