Abstract

A foam panel concrete form is provided for using concrete reinforcement rods which extend on each side of a joint in the foam panel concrete form and into complementary shaped openings in ties which hold two adjacent panels in a spaced and parallel relationship. The concrete reinforcement rod can pass into the openings in adjacent ties with little resistance in a first rotary position of the concrete reinforcement rod. When the concrete reinforcement rod is rotated to a second rotational position within the openings the reinforcement rod is in a tight frictional fit in the openings for helping to hold adjacent ties and the adjacent foam panels in a fixed relationship with respect to each other during a time when concrete is poured between the foam panels, thereby also serving to re-enforce the concrete after the concrete has cured.

Apparatus comprising:

a concrete reinforcement rod having a longitudinal axis and having a cross sectional shape transverse to the longitudinal axis, which cross sectional shape includes at least one diameter thereof which is larger than another diameter thereof;
a first foam panel having at least one side disposed substantially in a first plane;
a second foam panel having at least one side disposed substantially in a second plane which is substantially parallel to the first plane;
a first tie having one portion thereof disposed in the first foam panel and a second portion thereof disposed in the second foam panel;
a first opening disposed in the first tie, said first opening being approximately the same cross sectional shape as the cross sectional shape of the concrete reinforcement rod whereby the rod can pass into the first opening with little resistance in a first rotary position of the concrete reinforcement rod;
a third foam panel having at least one side disposed substantially in the first plane;
a fourth foam panel having at least one side disposed substantially in the second plane;
a second tie having one portion thereof disposed in the third foam panel and a second portion thereof disposed in the fourth foam panel;
a second opening disposed in the second tie, said second opening being approximately the same cross sectional shape as the cross sectional shape of the concrete reinforcement rod whereby the rod can pass into the second opening with little resistance in the first rotary position of the concrete reinforcement rod;
and
the concrete reinforcement rod having a second rotational position within the first and second openings wherein the reinforcement rod is in a tight frictional fit in the first and second openings of the first and second ties for helping to hold the first and second ties and the first, second, third and fourth panels to be held in a fixed relationship with respect to each other during a time when concrete is poured between the first and second and the third and fourth foam panels and thereby serving to re-enforce the concrete after the concrete has cured.
