ABSTRACT:
The instant invention constitutes a method of forming a concrete column and panel wall system, comprising the steps of: auguring a vertical pile hole; excavating about the pile hole a ground level recess for a pile cap; placing vertical rebars into the auger hole and cap recess; pouring concrete in situ into the pile hole and pile cap recess; positioning a pile cap plate on the poured concrete prior to the curing thereof; positioning opposing vertical ends of pre-cast concrete panels upon opposite ends of the pile cap plate and using forms to substantially define an H-shaped above-ground geometry each having vertical rebars therein, the panel ends also having horizontal re-bars extending into the geometry, thus horizontally and vertically positioning re-bars characterize substantially an entirely above-ground length of each column resultant of the H-shaped geometry; and casting in situ within volumes defined by the forms defining the above-ground geometry. Each combination of cast columns, as such, includes a first column corresponding to the pile hole and pile cap recess, and a second above-ground cast column.
