Abstract
Anchors and precast concrete structures including anchors are provided. An anchor includes a disk having a first dimension D1, a second dimension D2 and a first aspect ratio [D1/D2], wherein D1 and D2 are oriented perpendicular with respect one another, and wherein the first aspect ratio [D1/D2] is in a range between and including 0.75 and 1.25; and a head extending from a generally central portion of the disk in a direction generally perpendicular to D1 and D2, the head having a third dimension D3, a fourth dimension D4 and a second aspect ratio [D3/D4], wherein D3 and D4 are oriented perpendicular with respect to one another, wherein D3 is parallel with respect to D2 and D4 is parallel with respect to D1, and wherein the second aspect ratio [D3/D4] is less than 0.5.
Claims17
An anchor for lifting precast concrete, the anchor comprising:
- a disk having a first dimension D1, a second dimension D2 and a first aspect ratio [D1/D2], wherein D1 and D2 are oriented perpendicular with respect to one another, and wherein the first aspect ratio [D1/D2] is in a range between and including 0.75 and 1.25;
- and
- a head extending from a generally central portion of the disk in a direction generally perpendicular to D1 and D2, the head having a third dimension D3, a fourth dimension D4 and a second aspect ratio [D3/D4], wherein D3 and D4 are oriented perpendicular with respect to one another, wherein D3 is parallel with respect to D2 and D4 is parallel with respect to D1, wherein the second aspect ratio [D3/D4] is less than 0.5, wherein the head defines a height H, wherein H/D1 or H/D2 is less than 1.75,
- wherein the anchor defines a maximum load capacity C, as measured in a precast concrete structure, and wherein C/H is at least 6750 lbs/inch with the anchor spaced apart from any reinforcing material in the precast concrete structure.
A precast concrete structure comprising:
- a concrete body;
- and
- an anchor comprising:
- a disk having a first dimension D1, a second dimension D2 and a first aspect ratio [D1/D2], wherein D1 and D2 are oriented perpendicular with respect to one another, and wherein the first aspect ratio [D1/D2] is in a range between and including 0.75 and 1.25;
- and
- a head extending from a generally central portion of the disk in a direction generally perpendicular to D1 and D2, the head having a third dimension D3, a fourth dimension D4 and a second aspect ratio [D3/D4], wherein D3 and D4 are oriented perpendicular with respect to one another, wherein D3 is parallel with respect to D2 and D4 is parallel with respect to D1, and wherein the second aspect ratio [D3/D4] is less than 0.5,
- wherein the disk is disposed within the concrete body,
- wherein a first portion of the head is disposed within the concrete body,
- wherein a second portion of the head is exposed from the concrete body, and
- wherein the anchor defines a maximum load capacity C, as measured in a precast concrete structure, wherein the anchor defines a height H, and wherein C/H is at least 6750 lbs/inch with the anchor spaced apart from any reinforcing material in the precast concrete structure.
