Insulating corner wall form
View Patent ↗An insulating corner wall form comprises inner and outer foam panels arranged to provide a fixed space therebetween for receiving the poured concrete, the fixed space comprising a corner of about 90 degrees; a plurality of ties connecting the inner and outer panels. The ties comprise first and second corner ties, each extending from a respective first location at the inner panel to a respective second location at the outer panel. Each second location is a distance from a panel corner of the outer panel of from about 20% to about 80% of the thickness of the fixed space between opposite parallel portions of the inner and outer panels.
1. An insulating corner wall form comprising:
inner and outer foam panels arranged to provide a fixed space therebetween for receiving the poured concrete, the fixed space comprising a corner of about 90 degrees;
a plurality of ties connecting the inner and outer panels, the ties comprising:
first and second corner ties each extending from a respective first location at the inner panel to a respective second location at the outer panel, each second location being a distance from a panel corner of the outer panel of from about 20% to about 80% of the thickness of the fixed space between opposite parallel portions of the inner and outer panels,
wherein the first locations are on opposite sides of a panel corner of a concrete-facing surface of the inner panel, and
wherein at least one of the ties comprises a longitudinal body terminated by a pair of flanged ends, each flanged end being generally parallel with said opposite parallel portions of the inner and outer panels.
2. The insulating form of claim 1 , wherein the second locations are on opposite sides of the panel corner of a concrete-facing surface of the outer panel.
3. The insulating form of claim 1 , wherein each second location generally coincides with a line that generally bisects the fixed space between opposite parallel portions of the inner and outer panels.
4. The insulating form of claim 1 , wherein each second location is a distance from the panel corner of the outer panel of from about 40% to about 60% of the thickness of the fixed space between opposite parallel portions of the inner and outer panels.
5. The insulating form of claim 1 , wherein each second location is a distance from the panel corner of the outer panel of about 50% of the thickness of the fixed space between opposite parallel portions of the inner and outer panels.
6. The insulating form of claim 1 , wherein at least one of the ties is embedded within a respective one of the inner and outer panels during molding of that panel.
7. The insulating form of claim 1 , wherein said at least one tie has a unitary construction.
8. The insulating form of claim 1 , wherein each flanged end is embedded within a respective one of the inner and outer panels.
9. The insulating form of claim 1 , wherein said at least one tie is embedded within the inner panel such that a distal surface of said at least one tie is accessible from the outwardly-facing surface of the inner panel.
10. The insulating form of claim 1 , wherein said at least one tie is embedded within the outer panel such that a distal surface of said at least one tie is accessible from the outwardly-facing surface of the outer panel.
11. The insulating form of claim 1 , wherein the inner and outer panels are fabricated of expanded polystyrene (EPS).
12. The insulating form of claim 1 , wherein at least one of the ties is fabricated of high-impact polystyrene (HIPS).
