## 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.

## Claims

### Claim 1

A wall structure having an above ground wall, said wall structure comprising in combination:
a) a plurality of footings disposed at least partially in the ground;
b) said wall including a box lintel, said box lintel being supported at each end by adjacent ones of said footings and a plurality of courses extending upwardly from said lintel;
c) at least one tensioning rod extending upwardly from said box lintel into said wall;
d) said at least one tensioning rod having a lower end bent at least laterally with regard to the longitudinal axis of said tensioning rod and disposed within said box lintel;
e) at least one length of rebar extending longitudinally within said box lintel in proximity to and above each lower end of said at least one tensioning rod;
f) grout disposed within said box lintel for imbedding said rebar and said lower end of said at least one tensioning rod; and
g) at least one further tensioning rod extending upwardly from within each footing of said plurality of footings and adapted for resisting tilting of said wall, each of said further tensioning rods including a lower end bent laterally from said further tensioning rod.

### Claim 2 (depends on 1)

The wall structure as set forth in claim 1 wherein said at least one further tensioning rod extends upwardly within said wall at one end thereof.

### Claim 3 (depends on 1)

The wall structure as set forth in claim 1 wherein said lower end is bent back upon itself.
