A fixing device, such as an anchor or cavity wall tie, employs a deformable (radially expandible) sleeve element (6) to lock an end of a rod (1) in a bore (12) of a wall or like structure (11). Radial expansion may be achieved by axially compressing the sleeve element between a stop member (2) and an internally threaded member 9 arranged on a threaded portion (5) of the rod (1). The sleeve includes a rib (10), projecting from its radially outermost circumferential surface, which provides an interference fit for the sleeve in the bore prior to axial compression and thus substantially prevents rotation of the sleeve during compression.
An anchor for use in slab facings comprises an anchor bolt (2), which has an inner end that is adapted to be inserted into and to be embedded in mortar in a hole (6) formed in a wall (7) to be faced and an outer end provided with a transverse rod (1) for insertion into at least one bore formed in at least one edge face of at least one facing slab (9). To ensure that the anchor can be economically fixed and that the facing slabs can be mounted quickly, the anchor bolt (2) is provided at its inner end with a cylindrical enlarged portion (4), which has an embossed or channeled peripheral surface, and the anchor bolt is provided between the transverse rod (1) and the enlarged portion (4) with a driving sleeve (3), which is slidably mounted on the bolt and has a serrated or finned surface, which is larger in outside diameter than the enlarged portion (4).
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.
An axially extending sleeve (1), for use as an anchor secured by grout or a hardenable mass in a blind bore (2a) in a structural component (2), has an outside surface with a radially outwardly projection extending in the axial direction of the sleeve. The sleeve has a closed first end leading in the insertion direction and a trailing second end. The projection extends from the second end in the axial direction toward the first end. An elastic layer (3) is placed over the surface of the structural component containing the bore and a hole (3a) in the elastic layer is aligned with the bore in the component. When the sleeve (1) is inserted into the bore (2a), the projection (1d) forms a passageway through the elastic layer, so that air and excess grout can escape from the bore through the elastic layer.
A fixing device for a tensioning member of a prestressed concrete may unimly act holding force for the tensioning member on the overall peripheral surface of the tensioning member mating with the wedge. The device includes a stationary grip through which the tensioning member extends, a wedge press fitted to the grip with holding the tensioning member for fixing the tensioning member relative to the grip under a given tension, and a buffer member disposed between the tensioning member and the wedge, the buffer member having both elasticity and plasticity.
A facade anchor for incorporation into mutually aligned bore holes of a main wall and a bracket-mounted facade, consisting of an anchoring element (22) which extends from the bore hole base to the front of the facade, a pipe which extends from the bore hole inlet to the footing wall for injecting mortar, with the pipe having outlet openings (28) for mortar which are arranged inside the facade bore hole, and also of lamellar seals surrounding the pipe (22) on the inlets and outlets of the bore holes of the footing wall and facade, and of a nonuniform surface of the anchoring element for improving the bond of the injected mortar.
