Reinforced, dynamic lifting anchor for a structural member

Abstract

A lifting anchor for a structural member, such as a concrete panel, includes a head part able to be coupled with a gripping ring, a foot and a body interposed between the head and the foot, the head and the foot being intended to be embedded in the material of which the structural member is made, the anchor being obtained by folding at least one flat defining different successive portions that form the head, the body and the foot, respectively, of the anchor. The constituent portions of the foot of the anchor include two lower branches that diverge on either side of the body of the anchor. The anchor includes a reinforcing part interposed between the two flats or flat portions, extending from the head of the anchor along at least a part of the body.

1 . A lifting anchor for a structural member, comprising a head part able to be coupled with a gripping ring, a foot and a body interposed between the head and the foot, with the head and the foot being intended to be embedded in the material of which the structural member is made, with the anchor being obtained by folding at least one flat defining different successive portions that form the head, the body and the foot, respectively, of the anchor, with the constituent portions of the foot of the anchor comprising two lower branches that diverge on either side of the body of the anchor, and two branches that converge towards one another and extend from the diverging branches, and a reinforcing part interposed between the two flats or flat portions, extending from the head of the anchor along at least a part of the body. 
     
     
         2 . An anchor according to  claim 1 , wherein the reinforcing part is in the form of a flat. 
     
     
         3 . An anchor according to  claim 2 , wherein the reinforcing flat extends half-way up the body of the anchor. 
     
     
         4 . An anchor according to  claim 1 , wherein the reinforcing flat extends up to the lower ends of the converging branches. 
     
     
         5 . An anchor according to  claim 1 , further comprising a lock operably locking the converging branches against one another. 
     
     
         6 . An anchor according to  claim 5 , wherein the lock operably locks one converging branch to the other comprise at least one protrusion formed on the lower free edge of the converging branch, and a recess for accommodating such protrusion, provided in the thickness of the opposite converging branch from the lower free edge thereof, with the protrusion being engaged into the recess when the portions of the flat heads of the anchor and the reinforcing part interposed between same, are pressed against each other. 
     
     
         7 . An anchor according to  claim 6 , wherein the lock comprises a single protrusion transversally offset relative to the center of the free edge of the converging branch, and a cut forming the accommodating recess, with the two lower free edges of the two converging branches each comprising a single protrusion and one cut. 
     
     
         8 . An anchor according to  claim 6 , wherein the lock comprises several protrusions and several cuts, with the protrusions and the cuts alternating along the lower free edge of the converging branch, with the two lower free edges of the two converging branches each having several protrusions and several cuts forming notches. 
     
     
         9 . An anchor according to  claim 5 , wherein the reinforcement comprises a hole for the passage of the lock provided in the thickness of same. 
     
     
         10 . An anchor according to  claim 1 , wherein the anchor is formed by two identical flats assembled on either side of the reinforcement. 
     
     
         11 . An anchor according to  claim 1 , further comprising at least one outer tilt-up rib on each of the external faces of the two paired flats. 
     
     
         12 . An anchor according to  claim 11 , wherein the outer rib extends along a longitudinal axis of the anchor or along an inclined direction relative to such axis. 
     
     
         13 . An anchor according to  claim 1 , wherein the two paired flats, and/or at least one of the flats and the central reinforcement are secured together by means of a material bridge formed by a portion of a flat folded along a folding line. 
     
     
         14 . An anchor according to  claim 13 , wherein the folding line extends along a side edge of the anchor head, or an upper edge of the anchor head or a lower edge of the anchor foot.
