    摘要： An lifting insert (106), particularly for embedment in the edges of thin concrete elements (11) is disclosed. The insert has a head (120) at one end which has a through aperture for the connection of a co-operating lifting link (1) and another end 121 for embedment within the concrete. The head of the insert has an interior region (150) bounded on each side by an exterior region (160) which extends to the longitudinal edges (124) of the insert. The exterior region is thicker than the interior region and the boundary (155) between the two regions defines an abutment surface (156). The thickness and width of the interior region is dimensioned to allow the lifting link (1) to be connected to the head (120) of the insert and the thickness of the outer region is dimensioned so as to restrict the rotation of the lifting link when a load is applied normal to the axis of the insert, and to effectively transfer the load by a couple developed across the full cross- section of the insert e.g. when tilting the concrete element from a horizontal position to a vertical position.

    摘要： A recess former (30) is disclosed for use with anchors (35) which are to be cast into a concrete slab (61). The recess former (30) preferably includes a removable plug (36) and preferably rectangular lugs (57) which engage with corresponding apertures in the attachment head (34) of the lifting anchor and prevent the ingress of cement during casting of the slab (61). In addition, flaps (51) are preferably provided on the recess former to prevent the sides of the attachment head (34) from being encased in the concrete. Preferably the former is pivoted between open and closed positions and has a slightly V-shaped base which when abutted against a mold or formwork, urges the recess former into the closed position. Furthermore, a recess former (60-60I) is disclosed which stays behind after the casting and remains embedded in the concrete in order to provide a waterproof membrane between the recess (62) and adjacent reinforcing rods (58, 59, 71) thereby preventing corrosion of the reinforcing rods.

    摘要： A void former particularly for use with a lifting anchor cast into a concrete component is of two piece construction comprising a flexible element and a separate body which is substantially rigid. The flexible element is engageable with the head of the lifting anchor and is maintained in position by the rigid body which also acts to maintain the shape of the void during casting. After casting the rigid body is removed from the flexible element to thereby permit the flexible element to be disengaged from the lifting anchor by manipulation. The void former is thereby removable after casting without destruction of the void former and is thereby suitable for repeated use.

    摘要： 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.

    摘要： A lifting insert, particularly for embedment in the edges of thin concrete elements is disclosed. The insert has a head at one end which has a through aperture for the connection of a co-operating lifting link and another end for embedment within the concrete. The head of the insert has an interior region bounded on each side by an exterior region which extends to the longitudinal edges of the insert. The exterior region is thicker than the interior region and the boundary between the two regions defines an abutment surface. The thickness and width of the interior region is dimensioned to allow the lifting link to be connected to the head of the insert and the thickness of the outer region is dimensioned so as to restrict the rotation of the lifting link when a load is applied normal to the axis of the insert, and to effectively transfer the load by a couple developed across the full cross-section of the insert e.g. when tilting the concrete element from a horizontal position to a vertical position.
