Abstract: The disclosure relates to a lifting anchor for lifting a building element, such as a concrete panel, including a head part that can be attached to a lifting ring, a foot and a body interposed between the head and the foot. The body and the foot are intended to be immersed in the material of which the building element is made. The anchor extends in a main plane along a longitudinal axis. The anchor also includes at least two sub-parts, each one defining various successive portions respectively forming the head, the body and the foot of the anchor. The anchor includes at least one reinforcing piece interposed between the two flats or flat parts, extending from the head of the anchor over at least part of the foot.

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.

Abstract: A handling anchor for lifting, raising, turning over, transporting, and laying building elements, such as precast blocks or panels, essentially made of concrete and to be connected to a building element. The anchor includes a connecting head for connecting the building element to a handling machine, and a body portion including active parts that, when the anchor is connected to the construction element, ensure the adhesion of the anchor to the material of the building element. The body includes at least one land including at least one face.

Abstract: An anchor for construction elements, such as concrete panels, and including at least one flat part, an upper part for hanging on a handling engine and extending along a principal plane and a lower part for anchoring in the construction element. The lower part has two arms diverging in the direction of the lower end of the anchor, extending outside the principal plane, and forming, between them, an angle.

Abstract: The anchor rod (2) has a lateral bulge or projection (5) running along its length and constituting an anchoring element for providing anchoring in a direction perpendicular to the longitudinal direction of the rod (2). Such an anchor is applicable to lifting and handling panels, in particular panels made of reinforced concrete.

Abstract: A lifting ring having a lifting shackle and a yoke for coupling to the head of an anchoring device, the yoke being pivotally mounted to the bottom portion of the lifting shackle which is formed with two toroidal surfaces. The lifting shackle is formed with an eye which opens out onto the toroidal surfaces, the eye having two coupling faces and two inclined faces forming abutments that limit the relative motion possible between the yoke and the shackle.

Abstract: An anchoring piece for hardenable material such as concrete or plaster, comprising a grasping shank and a base of larger cross-section than that of the shank. The base (3) includes at least one support strip (5) whose top is hollowed out and intended to hold a reinforcing iron or bar (4) so as to fix together the assembly constituted by the anchoring piece and the reinforcing bar.

Abstract: A high-speed nut having two jaws capable of taking up two positions, one in which the central tapping is not engaged with a threaded rod, and a second in which the tapping is engaged therewith. According to the invention, the nut comprises two pieces (10, 11) which are hinged to each other about an axis (13), with pivoting of the pieces being caused by the front portion (15) of the pieces coming into contact with the object to be clamped.

Abstract: A coupler for hanging a prefabricated concrete body on a hoist. The connecting hook member has an arcuate slot and is provided on one end with an entrance opening for the slot, in which the connecting bolt head of an anchor bolt can be inserted. The connecting hook member is constucted as a hemispherically shaped component, on whose top side a hook pivot eye is attached, which is engaged pivotally with the suspension shackle in the shackle pivot eye. On the one side of the hook pivot eye the entrance opening formed as a mouth of the slot is positioned on the top side of the hemispherically shaped component. On the other side of the hook pivot eye the operating lever is positioned extending substantially radially. The hook pivot eye may be positioned in the plane of the slot. In this case the operating lever reaches a limit of its motion by contact with the bridging member of the suspension shackle. The hook pivot eye may however also be oriented perpendicularly to the slot.
