Passthrough concrete anchor
View Patent ↗A concrete anchor. The concrete anchor can be embedded within a concrete member to enhance lifting of the concrete member. The concrete anchor of the present invention can include a bar having a top, bottom and first and second sides, at least one attachment aperture, at least one reinforcement bar aperture, and at least one passthrough aperture. The concrete anchor can further include a projection positioned adjacent the second side of the bar. The projection can include an upwardly projecting top face, a downwardly projecting bottom face, a forwardly projecting front face and a rearwardly projecting rear face.
1. A concrete anchor comprising:
a bar having a top, a bottom, a front side, a back side, and first and second sides, at least one attachment aperture, at least one reinforcement bar aperture, at least one passthrough aperture, and a wedged shaped foot positioned adjacent the bottom of the bar; and
a projection, the projection being positioned adjacent the second side of the bar and extending away from sideway direction from the second side comprising an upwardly projecting top face, a downwardly projecting bottom face, a forwardly projecting front face that extends away in a frontward direction from the front side of the bar and a rearwardly projecting rear face that extends away in a rearward direction from the back side of the bar.
2. The concrete anchor of claim 1 , wherein the bar and the projection are integrally formed.
3. The concrete anchor of claim 1 , wherein the upwardly projecting top face is one of two upwardly projecting top faces.
4. The concrete anchor of claim 1 , wherein the downwardly projecting bottom face is one of two downwardly projecting bottom faces.
5. The concrete anchor of claim 1 , wherein the top of the bar comprises a first channel, a platform face, and a second channel.
6. The concrete anchor of claim 1 , wherein the second side of the bar further comprises a downwardly projecting side face, and an extending side face.
7. The concrete anchor of claim 1 , further comprising a crescent shaped indentation defined in the first side of the bar.
8. The concrete anchor of claim 1 , further comprising a shear plate aperture defined in the bar and positioned adjacent the second side of the bar.
9. The concrete anchor of claim 1 , wherein the projection includes a first side face and a second side face, the first side face at least partially defining at least one of a shear plate aperture and a passthrough aperture, and the second side face at least partially defining the second side of the bar.
10. The concrete anchor of claim 1 , wherein the at least one passthrough aperture is designed so that the weight of the anchor is reduced by at least 30% from the weight of the anchor without the passthrough aperture.
11. The concrete anchor of claim 1 wherein the first and second sides of the bar each defining a width, and the projection further has extending side faces defining a width, wherein the width of the projection is greater than the width of the first and second sides of the bar.
12. The concrete anchor of claim 1 wherein the bar further has a slanted downwardly projecting side face and the projection further has an extending side face; and
wherein the slanted downwardly projecting side face projects downward at an angle from the top of the bar to the extending side face.
13. The concrete anchor of claim 1 wherein the bar further has a shear plate aperture adjacent to the second side of the bar; and wherein the projection is positioned adjacent to the shear plate aperture of the bar.
14. The concrete anchor of claim 5 , wherein the top of the bar further comprises a first upwardly projecting face and a second upwardly projecting face.
15. A concrete anchor comprising:
a rectangular shaped bar having a top, a bottom, a front side, a back side, a first side, and a second side, at least one attachment aperture, at least one reinforcement bar aperture, at least one passthrough aperture, and a wedged shaped foot positioned adjacent the bottom of the rectangular shaped bar; and
a projection positioned adjacent the second side of the bar and extending away from sideway direction from the second side the projection comprising an upwardly projecting top face, a downwardly projecting bottom face, a forwardly projecting front face that extends away in a frontward direction from the front side of the bar, and a rearwardly projecting rear face that extends away in a rearward direction from the back side of the bar.
16. The concrete anchor of claim 15 , wherein the rectangular shaped bar is integrally formed with the projection.
17. The concrete anchor of claim 15 , wherein the second side of the rectangular shaped bar further comprises a downwardly projecting side face and an extending side face, the extending side face forming at least a portion of the projection.
18. The concrete anchor of claim 15 , further comprising a shear plate aperture defined in the bar and positioned adjacent the second side of the bar.
19. The concrete anchor of claim 17 , further comprising a shear plate aperture defined in the bar and positioned adjacent the extending side face.
20. The concrete anchor of claim 15 , further comprising a crescent shaped indentation defined in the first side of the rectangular shaped bar.
21. The concrete anchor of claim 15 , wherein the top of the rectangular shaped bar includes a first channel, a platform face and a second channel to allow engagement of the rectangular shaped bar with lifting hardware.
22. The concrete anchor of claim 15 , wherein the at least one passthrough aperture is designed so that the weight of the anchor is reduced by at least 30% from the weight of the anchor without the passthrough aperture.
