US 5,704,180 A · Insulating concrete form utilizing interlocking foam panels

Abstract

A concrete form system in which a plurality of foam panels are interlocked transversely, horizontally and vertically by a plurality of connectors. The panels have opposed upper and lower ends, with a plurality of coplanar passages extending into the upper ends at regularly spaced intervals. An equal plurality of coplanar passages extend into the panels' lower ends at the same regularly spaced intervals to vertically align each upper end passage with a corresponding lower end passage. Each connector has a first bar which interconnects transversely opposed first and second parallel, vertically extending planar segments; and, a second bar interconnecting identical transversely opposed third and fourth parallel, vertically extending planar segments. A latticework interconnects the two bars in spaced parallel relationship and maintains separate coplanar alignment of (i) the first and third planar segments, (ii) the second and fourth planar segments, and (iii) the two bars. The upper and lower end panel passages are sized and shaped to receive corresponding halves of one of the connector planar segments.

Dependent claims

A foam panel for constructing a concrete form, said panel characterized by:

(a) opposed upper and lower ends;
(b) a plurality of coplanar upper end passages, each of said upper end passages contained within and extending a preselected depth into said upper end, said upper end passages displaced at regularly spaced intervals along said upper end;
(c) a plurality of coplanar lower end passages, each of said lower end passages contained within and extending a preselected depth into said lower end, said lower end passages displaced at regularly spaced intervals along said lower end, each of said upper end passages being aligned vertically and coplanar with a corresponding one of said lower end passages;
and,
(d) for each of said upper and lower end passages, an angular passage perpendicularly intersecting said respective upper or lower end passage along said preselected depth and extending toward but not substantially through one longitudinal face of said panel.
