(54) | Anchoring member |
(57) An anchoring member for hoisting pieces of concrete, cement or the like, of the type
consisting in a lost tube inserted in the concrete piece, shaped from a length of
tubing of a length smaller than the height of the concrete piece in which it will
be inserted, with a rectangle-shaped upper mouth (6). Near the opposite mouth it has
a flattening in its wall that shapes two opposite triangle-shaped angular folds (2)
defining on the inner surface of the tube two straight edges (3) of a length greater
than diameter of said tube, which shape a widening in the flattened area. There are
two slight transversal grooves (5) in a perpendicular direction to said widening in
the upper zone from this flattened area where the flattening starts. The anchoring member is such that the inner surfaces of the triangle-shaped angular folds (2) remain in contact with or near each other along the edges of said folds. It is furthermore such that the rectangle-shaped upper mouth has dimensions such that it allows entry in it of the rectangular foot (10) of a hoisting eyebolt (7) and which remains locked inside of the rectangular mouth (6) of the anchoring member when this rectangular foot (10) is turned in a right angle. |
