摘要:
An expansion dowel assembly is made up of an axially extending dowel body and an expansion member in contacting engagement with the dowel body. The expansion member extends in the axial direction of the dowel body and is formed by a main part and an extension part projecting axially from the main part in the insertion direction of the assembly into a borehole. The cross-sectional area of the extension part transverse to the axial direction is smaller than the adjacent corresponding cross-sectional area of the main part. The extension part is shaped relative to the main part to increase the contact area of the expansion member with the dowel body and to prevent the development of excessively high surface pressures at the front end of the expansion member.

A metal expansion dowel is made up of an axially elongated cylindrically shaped expansion sleeve and an expansion element formed monolithically with the sleeve. The expansion sleeve has a leading end and a trailing end. The sleeve has an opening with the opposite edge surfaces extending in the axial direction converging toward the leading end. The expansion element is located in the opening and is secured to the sleeve by a separable web. The expansion element is wedge-shaped and narrows in the leading end direction. An inwardly projecting stop is formed in the expansion element. When an axial force is directed toward the leading end against the stop, the web is separated from the sleeve and the expansion element is displaced axially toward the leading end of the sleeve moving along the opposite edge surfaces of the opening and widening the sleeve. Due to the converging arrangement of the opposite edge surfaces of the recess, the dowel has a post-expansion characteristic during subsequent axial loading of the expansion sleeve after it is anchored in place.

In a dispensing device for filling boreholes with a single or multi-component adhesive, filler, sealer or primer, the material is conveyed from storage containers holding the individual components through a supply pipe and an outlet nozzle which dispenses the material directly into the borehole. By manually operating a handle lever, material is displaced out of the storage container into the supply pipe. Further, an actuating unit operated by the handle lever is connected to the outlet nozzle for telescoping it relative to the supply pipe whereby material is displaced out of the supply pipe through the outlet nozzle into the borehole.

An axially elongated fastening element is made up of an anchor bolt and a spreader wedge each having a wedge surface. Initially the two parts are inserted in the unspread condition into a borehole. By providing relative movement in the axial direction between the wedge surfaces, the fastening element is anchored in the borehole. The wedge surfaces are divided into at least two portions each disposed at a different angle relative to the axis of the fastening element. The initial spreading action is effected when the portion of the wedge surfaces having smaller angles slide relative to one another.

An attachment system for securing a rod member in a mounting opening of a constructional component (44; 74; 97) includes a receiving sleeve (5; 37; 64; 73; 93) for receiving the rod member (23; 40), and an actuation member (4; 35; 62; 72; 81; 92) connected with the receiving sleeve (5; 37; 64; 73; 93) for substantially radially displacing the engagement elements (24.1; 24.2; 49.1; 49.1; 69.1; 69.2; 98.1; 98.2) of the receiving sleeve, which engage the rod member, from a first position in which the rod member is received in the receiving sleeve (5; 37; 64; 73; 93) to a second position in which the rod member is locked in the receiving sleeve.
摘要:
A fastener having a grip member (1) that is insertable into a mounting space (3) of a hollow structure (2) and serves in the detachable fastening of an object to the hollow structure. The grip member (1) is rotatable inside the hollow structure such that the grip member (1) grips behind holding projections provided inwardly of the hollow body longitudinal walls. The holding projections are for fastening of the object between a stop (7), that outwardly abuts the edges of the hollow structure's longitudinal walls (4) lining the mounting space and can be fixedly clamped to the grip member (1). A spring biased element (13) acting perpendicular to the stop (7) is arranged between the grip member and the stop. The result is that pre-fixation of the fastener to the hollow structure is made possible. By means of a coupling (15) between the stop (7) and the rear grip member (1) its positions are precisely fixed.

A fastening device for securing tubes, pipes and the like is formed of a mounting rail (3) having a C-shaped cross-section and an elongated space (2) and a retaining plate (1). The retaining plate (1) has a tapped through hole running transverse to the elongated space (2), the tapped hole has an internal thread for form-locking reception of a fastening element. Further, the retaining plate (1) has on the side (13) facing inwardly from the elongated space (2), at least one web facilitating rigidity and positioning, in order to provide a manageable and economical fastening device with high load capacities (P).
