摘要:
The anchoring rod for anchoring an article to a base using a compounded mass including a synthetic resin, has a threaded portion at its rear end for fixing the article; a threaded nut engagable on the threaded portion for applying a mounting torque; a head having a shoulder facing toward the rear end, an outer surface tapering towards the front end of the anchoring rod and having a wedge-like tip at the front end; a conical portion connecting the head and the threaded portion and tapering toward the head; and a resilient annular washer bearing on the shoulder of the head.

The invention relates to a damping apparatus having a through-hole for an anchor (2) and having a damping element (11). In order to provide an improved damping apparatus (1) which can damp a wide spectrum of dynamic loads but which undergoes only insignificant deformation under working load, it is proposed that the damping apparatus (1) have a dissipation element (6) which, until a maximum relative force between the anchor (2) and a fastened article (12) fastened by the anchor (2) is exceeded, is elastically deformable and, after the maximum relative force has been exceeded, is elastically-plastically or plastically deformable.

The impact-type anchor (1) consists of a metal sleeve (2) provided with a throughgoing passage (3) tapering towards a leading end of the sleeve, into which bore an expander body (5) can be driven to expand the impact-type anchor. The throughgoing passage (3) has a rear cylindrical portion provided with an internal thread (4) as well as a tapering portion. So that the metal sleeve can be inexpensively manufactured while providing pull-out values that are the same as those of a metal sleeve made of solid material, the metal sleeve is stamped out of a sheet metal blank and then rolled up to form a sleeve which is joined at its seam. Furthermore, in order to form the tapering internal bore the expandable legs (7) have a first section (7a) that is bent inwards and a second section (7b) that is bent onto the outer face of the first section. The two sections (7a, 7b) resting one against the other are connected non-displaceably to one another, for example, by means of a punched point (9).

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.
摘要:
A fixing arrangement in the edge region of a building element of, for example, concrete, has a close-to-edge anchoring in the building element, and a fiber reinforcement is attached to the building element by a bonded connection, for example by adhesive bonding, in the region of the anchoring. Preferably, the reinforcement extends over an edge onto an edge face of the building element.
