  • Publication number: 20060265982
    Abstract: A wall system or structure includes a lintel supported wall and footings for locating the lintel above ground. Tensioning rods extend upwardly from each footing for directly engaging an end of the wall and for securing a post to the footing, which post includes a slot for engaging the vertical edge of the wall. A plate resting on each footing may be used to support an end of the lintel above ground. Tensioning rods extend vertically from within the lintel upwardly into the wall.

  • Patent number: 6632048
    Abstract: A retaining wall, supported by a footer, foundation or conventional retaining wall, includes a plurality of post-tensioning rods anchored in the underlying support and extending through the cells of blocks forming the courses of the retaining wall. An elongated apertured plate or a plurality of individual plates rest upon the next to last course to penetrably receive the threaded ends of each of the rods. Nuts engage the threaded ends of the rods to draw the rods to the plate and place them in tension. The top course rests upon the plate or plates and may be constructed as a bond beam. The rods extending from the support may be located adjacent the said side of the retaining wall and bent away therefrom to penetrate the plate or plates at the lateral midpoint of the plate or plates and thereafter extend essentially vertically upwardly. To add an extended wall supported on the bond beam, couplings may be threadedly engaged with the rod ends. Further rods threadedly engage the couplings and extend upwardly.

  • Patent number: 6431797
    Abstract: A masonry retaining wall is constructed using a footer placed at or beneath a lower grade level with vertically extending post-tensioning rods extending therefrom. The post-tensioning rods are provided with upset ends and flange members close to a right angle bend to provide appropriate anchoring in the footer and to increase the pull out strength of the rod. A plurality of courses of masonry block are positioned on the footer with the vertically extending post-tensioning rods threaded through voids in the block. Flange members are positioned on the ends of the respective post-tensioning rods and nuts are used on the threaded ends thereof to apply a predetermined tensioning force to each of the post-tensioning rods.
