Abstract
A masonry block system is disclosed incorporating a plurality of courses of masonry block, each block of which is formed with minimum webbing to minimize heat flow therethrough. The wall system is formed into a unitary structure through the utilization of post-tensioning rods tied to reinforcing rods in the wall footer and extending through the voids in the respective blocks to a top plate positioned on top of the wall. The rods are threaded and are post-tensioned; the voids contain a polyurethane foam.
Claims2
A wall structure comprising:
- (a) a concrete footer having an anchoring means therein;
- (b) a plurality of post-tensioning rods connected to said anchoring means and extending vertically from said footer;
- (c) a plurality of stacked masonry building blocks arranged in courses with mortar therebetween and having voids therein;
- (d) a plate positioned on the top course of said blocks;
- (e) said rods extending through said voids in non-contacting relationship to said blocks, grouting or other masonry products and through said plate;
- (f) tensioning means mounted on said plate and secured to said post-tensioning rods for maintaining a predetermined tension in said rods;
- (g) said masonry building blocks each having opposing parallel faces interconnected by a single web member;
- (h) means defining thermal insulation material in said voids to increase the thermal resistance of said wall structure to provide a wall structure having an R value greater than 10;
- and
- (i) a steel lintel member extending over an opening provided in said wall structure, said lintel including a plurality of vertically extending rods connected thereto, each of said rods extending through voids in said blocks positioned above said lintel.
