Abstract
Apparatus, method and product of in situ attachment of insulation panels to poured concrete walls as the walls are formed. Polymeric F-shaped strips are attached to novel tie bars by spring clip retainers, and receive the edges of insulation panels to hold them against the forms so that uncured concrete is poured between the forms and against the panels. After the concrete is cured, the forms are removed, leaving the spring clips and tie bars in the concrete, and resulting in a concrete wall having insulation panels and secured strips, the strips also serving to receive dry wall fasteners.
Claims4
An insulated poured concrete wall structure comprising:
- a concrete wall having opposite wall surfaces;
- a plurality of vertically spaced tie bars extending through said concrete wall;
- vertically elongated polymeric retaining strips on at least one of said wall surfaces, extending astraddle said plurality of vertically spaced tie bars, and having a leg embedded in said concrete wall;
- insulation panels on at least one of said wall surfaces and having edges retained by said retaining strips;
- said retaining strips being F-shaped so as to have U-shaped channels and an extending leg, said extending leg being said embedded leg, and said U-shaped channels receiving and retaining said insulation panel edges;
- and
- retainers between said vertically elongated strips and said plurality of tie bars and embedded in said concrete wall.
