Z-bend, nestable ties
A tie for insulated concrete forms that has a Z-bend configuration so that the tie is nestable with similar Z-bend ties in order to optimize the cubic volume and the weight of a container of nested ties for shipment.
1. A tie for an insulated concrete form comprising:
a. a series of crosstie elements intersecting with and connected to a series of reinforcing elements, wherein the crosstie elements each have a first side section, a central section, and a second side section, the second side section including a first portion connected to the central section and a second portion connected to the first portion;
b. a first planar section defined by the intersections of the central sections of the crosstie elements and reinforcing elements, the first planar section having a first side and a second side;
c. a second planar section defined by and including the first side sections of the crosstie elements, wherein the second planar section is connected along a line to the first side of the first planar section at an angle of approximately 90 degrees and wherein the second planar section coincides with a first furring strip that is attached to the first side sections;
d. a third planar section defined by and including the first portions of the crosstie elements, wherein the third planar section is connected along a line to the second side of the first planar section at an angle greater than 90 degrees; and
e. a fourth planar section defined by and including the second portions of the crosstie elements, wherein the fourth planar section is connected along a line to the third planar section at an angle less than 90 degrees and wherein the fourth planar section coincides with a second furring strip that is attached to the second portion of the second side section.
2. The tie of claim 1 , wherein the third planar section is connected to the second side of the first planar section at an angle of about 120 degrees.
3. The tie of claim 1 , wherein the third planar section is connected to the second side of the first planar section at an angle of about 135 degrees.
4. The tie of claim 1 , wherein the at least one crosstie element is configured to receive a like crosstie element of a second tie for nesting the first tie and the second tie with the first planar section of the first tie and the first planar section of the second tie parallel to each other.
