Slotted Sleeve Spread By Tapered Expander Patents (Class 411/57.1)
  • Publication number: 20100003101
    Abstract: A hybrid drop-in anchor includes an expansion sleeve. A split base region of the anchor body has a setting plug to be driven baseward by setting tool for preliminary setting in a borehole. The sleeve resiliently surrounds an external annular body recess of the body above a tapered base region portion, and has a clip arcuate portion extending at least most of the periphery around the external annular recess. Clip segments extend baseward from the arcuate portion. Each segment has proximal portion having a segment intrinsic radial thickness and includes a distal portion having at least one intrinsic projection, namely a boss, standing radially outwardly from the outer surface of the distal portion. The boss is raised from the outer surface of the distal portion without there being a corresponding cavity of said blank on an inner surface of the distal portion, to provide a projection of thickened total depth greater than the segment intrinsic radial thickness.

    Abstract: The invention relates to an expansible anchor (10) for anchoring in a cylindrical drilled hole (40). The invention proposes constructing the expansible anchor (10) with a tubular basic anchor part (12), on which a hollow conical expansion portion (22) is formed by means of a forming procedure, on which expansion portion (22) an expansion sleeve (14) bent out of sheet metal is mounted. As a result of axial displacement of the expansion sleeve (14) on the expansion portion (22), the expansible anchor (10) becomes anchored in the drilled hole (40). The expansible anchor (10) exhibits subsequent expansion behaviour in the event of widening of the drilled hole (40), for example as a consequence of crack formation.

  • Publication number: 20040136802
    Abstract: An expansion bolt includes a sleeve in which a central bore is defined, comprising a rear inner-threaded section and a front tapering section. Radial slits are defined in a front end portion of the sleeve and partially in communication with the tapering bore to form a plurality of deformable pawls. At least one spherical member is received in the tapering bore and has a diameter greater than a smallest diameter of the tapering bore whereby the spherical member is effectively retained in the tapering bore. A driving member having external threading is threadingly received in the threaded bore for axially engaging the spherical member. By screwing the driving member, the spherical member is forced toward the front end of the sleeve and due to the tapering configuration of the tapering bore, the movement of the spherical member toward the front end of the sleeve forces the pawls to deform outward in a radial direction thereby securing the expansion bolt in a hole defined in for example a wall.

On the threaded bolt (8), between the expander (9) and the expansion member (3), there is arranged a spacing element (10). In the event of a tensile load, the expander (9) enters the spacing element (10) and forms a deformation zone that corresponds to the length of the spacing element (10). As a result of the friction and deformation occurring in the deformation zone, overloads are absorbed and, consequently, the fastening element is prevented from coming out or the threaded bolt from breaking off.
