Abstract
The disclosure is for a method and apparatus for constructing a concrete wall with a single pouring of concrete. The mold for the pouring of the wall is formed essentially of plastic foam insulation which remains attached to the finished wall to serve as thermal insulation. The wall structure is therefore self jigging and requires no elaborate mold structure or any time or labor to remove the finished wall from the mold.
Claims19
A prefabricated concrete wall panel comprising:
- a concrete sheet forming a first wall surface;
- concrete studs formed with and protruding from a second surface of the concrete sheet so that each stud has two side surfaces and an end surface extending beyond the concrete sheet;
- insulation sheets covering the second surface of the concrete sheet between the concrete studs;
- individual insulation slabs covering each of the two side surfaces of each of the concrete studs and interlocking with the insulation sheets covering the second surface of the concrete sheet;
- and
- channels holding the insulation slabs covering the side surfaces of the studs in place.

A method of constructing a wall panel comprising:
- placing channels with vertical legs at the location of each concrete stud to be produced, with the open side of the channel facing upward;
- placing insulation within each channel to form stud cavities, with vertical insulation placed adjacent to the vertical legs of the channels and bottom insulation placed at the bottom of the channels between the vertical legs of the channels;
- placing top insulation sheets on top of the vertical insulation in the channels to form a solid boundary between the stud cavities for holding unset concrete;
- pounding concrete onto the insulation sheets and into the stud cavities;
- and
- permitting the concrete to harden to form a wall panel with a sheet of concrete formed with concrete studs and with insulation covering the studs and the surfaces between the studs.
