Abstract
A concrete insert having a U-shaped part with two legs and a bridge between them, the bridge having a hole in which an internally threaded coupling is engaged with a friction fit, a bolt threaded in the coupling to extend above the bridge so that the position of the coupling with respect to the U-shaped element can be set by tapping the bolt and held by friction against the side of the hole in the bridge.
Claims6
A concrete insert comprising a U-shaped support having two legs connected with a bridge, said legs terminating in lateral flanges which lie substantially in a plane.
- an opening in said bridge,
- a coupling having connecting means, said coupling positioned between said legs, said coupling comprised of an external surface dimensioned to be in frictional engagement with said opening,
- an elongated connectable element engaged with said coupling, and
- a position-adjusting means on said connectable element, said position-adjusting means being movable axially on said connectable element and spanning the diameter of said opening.
