Abstract
Composite precast concrete panels are described herein having have an anchor that distributes forces imposed on the anchor through concrete wythes of the panels. Specifically, pins can be embedded in at least one concrete wythe, and then the anchor is secured to the wythe as described herein. The anchor extends through another Wythe to selectively connect to a hoist system that moves and places the composite precast concrete panel. The forces imposed on the anchor are distributed through the pins and into multiple concrete wythes to prevent failure of the composite precast concrete panels and improve safety.
Claims16
An apparatus for selectively securing a plate to a pin in a precast concrete panel, comprising:
- a plate having a substantially planar shape with an aperture having an aperture width;
- a slot extending through said plate, said slot having a slot width that is smaller than said aperture width, wherein said slot and said aperture combine to form a continuous opening, and said slot tapers from a top width at a top surface of said plate to said slot width at a bottom surface of said plate;
- a pin having a pin width that is greater than said slot width, wherein a recess in said pin defines a recess width that is smaller than said slot width;
- wherein, in a first position, said pin is adapted to pass through said aperture in said plate in a longitudinal direction;
- and
- wherein, in a second position, said pin is adapted to move into said slot in said plate in a lateral direction such that said recess of said pin is at least partially positioned in said slot of said plate, and a inner surface of said plate that defines said slot and a surface of said pin that defines said recess engage each other to secure said plate to said pin and distribute a force from said plate to said pin.
An apparatus for selectively securing a plate to a pin in a precast concrete panel, comprising:
- a plate having a substantially planar shape with an aperture having an aperture width;
- a slot extending through said plate, said slot having a slot width that is smaller than said aperture width, wherein said slot and said aperture combine to form a continuous opening;
- a pin having a pin width that is greater than said slot width, wherein a recess in said pin defines a recess width that is smaller than said slot width;
- wherein, in a first position, said pin is adapted to pass through said aperture in said plate in a longitudinal direction;
- wherein, in a second position, said pin is adapted to move into said slot in said plate in a lateral direction such that said recess of said pin is at least partially positioned in said slot of said plate to secure said plate to said pin and distribute a force from said plate to said pin;
- and
- a plug adapted for positioning in said aperture to secure said pin in said slot of said plate.

- a pin having a pin width that is greater than said slot width, wherein a recess in said pin defines a recess width that is smaller than said slot width;
- wherein, in a first position, said pin is adapted to pass through said aperture in said plate in a longitudinal direction;
- wherein, in a second position, said pin is adapted to move into said slot in said plate in a lateral direction such that said recess of said pin is at least partially positioned in said slot of said plate to secure said plate to said pin and distribute a force from said plate to said pin;
- and
- a collar positioned about said pin, wherein said collar has an outer dimension greater than said aperture width, and said collar allows said pin to pass through said aperture in said plate to a predetermined distance in said first position.
