Apparatus, system, and method for assembling, aligning, leveling, and squaring in-ground pool walls

A method of securing a cleat member of a pool wall assembly, alignment, squaring and leveling apparatus to a pool wall panel, comprising:

• providing a fastener having an internally threaded aperture
• securing the fastener to a bottom flange of the pool wall panel at a desired location;
• providing an adjustment member having a head section and a threaded shaft section;
• threadably passing the threaded shaft section into the threaded aperture of the fastener from an inwardly facing surface of the bottom flange of the pool wall panel by rotating the adjustment member in a first direction;
• providing a cleat member including a plate having at least one through-hole in the plate dimensioned to receive a rebar, a cleat formed in a side wall of the plate for engaging a ground surface, a cavity defined within the cleat member, and a collar attached to the plate extending over the cavity, the collar having a plurality of cutouts in a peripheral edge of the collar to serve as welding locations for securing the collar to the plate, and a threaded aperture adapted to receive an outer end of the threaded shaft section of the adjustment member within the cavity, wherein the threads on the threaded shaft section of the adjustment member have a lesser shear stress than the threads on the threaded aperture in the collar;
• and
• passing the outer end of the threaded shaft section of the adjustment member into the threaded aperture in the collar by rotating the adjustment member in the first direction;
• and continuing to rotate the adjustment member in the first direction until the outer end of the shaft section is pressing against an inner wall of the cavity with a sufficient force to cause one or more threads on the threaded shaft section of the adjustment member in contact with the threads in the aperture in the collar to shear as a result of said force, rotatably and pivotably securing the cleat member to the shaft section.
