Abstract

A connector member and system is provided for selectively connecting to an anchor of a precast concrete structure. The connector member comprises arcuate members for rotating the anchor into a position of secure interconnection and serves as a force-transmitting device for contacting the anchor and associated features and structures.

Claims

1. A connector member for selective interconnection to an anchor member provided in a precast concrete structure, the connector member comprising:

a first planar portion comprising a threaded aperture;

a fastener provided in and selectively removable from the threaded aperture, wherein the fastener extends substantially perpendicularly from the first planar portion;

an adjustment member provided on the fastener, the adjustment member comprising a nut adapted to secure at least one additional feature to the connector member;

a second planar portion and a third planar portion extending substantially perpendicular from said first planar portion, said second and third planar portions being substantially parallel to each other;

a first arcuate member and a second arcuate member extending from said second and third planar portions, respectively, said first and second arcuate members being substantially parallel to one another and arcuate about substantially the same axis;

a stop provided between the first arcuate member and the second arcuate member, the top adapted to limit rotation of the connector member about the anchor member; and

a partially enclosed void formed between said first planar portion, said second planar portion, said third planar portion, and said first and second arcuate members.

2. The connector member of claim 1, wherein said first and second arcuate members comprise inclined ramps for communicating with a flange of said anchor member.

3. The connector member of claim 1, wherein said fastener comprises a threaded bolt.

4. The connector member of claim 1, wherein said fastener comprises a threaded fastener extending from said aperture, said threaded fastener comprising the adjustment member for securing the additional feature to said threaded fastener.

5. The connector member of claim 4, wherein at least one of a wall brace and strut is secured to said threaded fastener by said adjustment member.

6. The connector member of claim 1, further comprising a rearward portion extending between said first and second arcuate members, said rearward portion adapted to limit rotation of said connector member about a flange of said anchor member.

7. The connector member of claim 1, wherein said first planar portion is adapted for substantially planar placement with a surface of said precast concrete structure.

8. The connector member of claim 1, further comprising a precast concrete panel comprising a void, wherein an anchor member is disposed in said void.

9. A connector member for selective interconnection to an anchor member provided in a precast concrete structure, said connector member comprising:

a first planar portion adapted for substantially parallel placement with a surface of said precast concrete structure, said first planar portion comprising a threaded aperture;

a fastener provided in and selectively removable from the threaded aperture, wherein the fastener extends substantially perpendicularly from the first planar portion;

a second planar portion and a third planar portion extending substantially perpendicular from said first planar portion, said second and third planar portions being substantially parallel to each other;

a first arcuate member and a second arcuate member extending from said second and third planar portions, respectively, said first and second arcuate members being substantially parallel to one another and arcuate about substantially the same axis, wherein said first and second arcuate members comprise inclined ramps for communicating with a flange of said anchor member;

a rearward portion extending between said first and second arcuate members, said rearward portion adapted to limit rotation of said connector member about a flange of said anchor member; and

a partially enclosed void formed between said first planar portion, said second planar portion, said third planar portion, said rearward portion, and said first and second arcuate members.

10. The connector member of claim 9, wherein said fastener comprises a threaded bolt.

11. The connector member of claim 9, wherein said first and second arcuate members comprise a bottom surface with a radius of curvature, said radius of curvature is between approximately 0.5 inches to approximately 4.0 inches.

12. The connector member of claim 9, wherein said first and second arcuate members comprise a bottom surface with a radius of curvature, said radius of curvature is between approximately 1.50 inches to approximately 1.75 inches.

13. The connector member of claim 9, wherein said first and second arcuate members comprise a bottom surface with a radius of curvature, said radius of curvature is approximately 1.688 inches.

14. A system for selective interconnection to a preexisting anchor member provided in a precast concrete wall panel, the system comprising:

a connector member for interfacing with a preexisting anchor member, the connector member comprising;

(i) a first planar portion comprising a threaded aperture;

(ii) a second planar portion and a third planar portion extending substantially perpendicular from said first planar portion, said second and third planar portions being substantially parallel to each other;

(iii) a first arcuate member and a second arcuate member extending from said second and third planar portions, respectively, said first and second arcuate members being substantially parallel to one another and arcuate about substantially the same axis;

(iv) a partially enclosed void formed between said first planar portion, said second planar portion, said third planar portion, and said first and second arcuate members;

a threaded fastener selectively connected with said threaded aperture, said threaded fastener comprising a length, said threaded fastener partially disposed in and extending from said aperture; and

a support member comprising at least one of a wall brace and a strut, said support member selectively interconnected to said threaded fastener.

15. The connector member of claim 14, wherein said threaded fastener extends substantially perpendicular to said first planar portion.

16. The connector member of claim 14, further comprising an adjustable member wherein said adjustable member is provided on said threaded fastener, and wherein said adjustable member is translatable along said length of said threaded fastener.

17. The connector member of claim 16, wherein said adjustable member is selectively translated to secure said support member to said threaded fastener.
