An angle-shaped support member consists of a unitary element formed into a pair of legs extending normally to one another and interconnected at their adjacent ends by an outwardly extending rectangularly shaped box section. The opposite ends of the legs from the box section each have an outwardly directed flange. The flanges and walls of the box section have axially aligned openings through which bars can be fitted. The openings in the flanges and walls are offset laterally relative to one another to avoid any interference between the bars which extend through them.

A sound dampening fastening element includes a sound dampening body, an anchoring member and a support member. The dampening body is prism-shaped and formed of a resilient material. The anchoring member has a head and a shank with the head and a portion of the shank embedded within the dampening body and the remaining portion of the shank extending outwardly from the dampening body. The support member is partly embedded within the dampening body and the remaining part extends outwardly from the opposite side of the dampening body from which the shank extends. The support member has a shaped configuration with wall sections within the dampening body combining to form an opening through which the shank extends. The diameter of the opening is greater than the diameter of the shank but smaller than the diameter of the head of the anchoring member. The part of the support member extending outwardly from the dampening body includes openings for receiving a belt-like support element and also a threaded opening.

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.

A manually operable device is provided for dispensing measured amounts of a mastic-like or paste-like multi-component material. The components are supplied in separate containers and each container has an axially displaceable ejection piston. The pistons are displaced by piston rods and each piston rod can be gripped by a clamping jaw and the jaw is displaced via a manually operated lever and a stirrup. A support bearing member affords lateral support for the piston rods and the clamping jaws are pivotally mounted on the bearing member. The drive for the piston rods acts through the clamping jaw and the support bearing member so that each rod is displaced axially and does not need to be connected to the other. Due to a symmetrical arrangement of the forces acting on the support bearing member, the forces cancel one another out.

In a device for the melting and measured discharge of a thermoplastic adhesive, the adhesive material is melted within a melting chamber and then flows out through a discharge nozzle. The discharge nozzle contains a spring biased valve body for blocking flow out of the melting chamber until the biasing force is overcome. If the spring fails and cannot return the valve body into position to seal the melting chamber, the discharge nozzle is arranged to prevent the valve body from blocking the flow of the melted adhesive material through and out of the discharge nozzle.

An expansion anchor assembly for use in a borehole formed in a receiving material has a leading end and a trailing end relative to the insertion direction of the assembly into the borehole. The expansion anchor assembly includes a tie rod with an expansion cone at its leading end, an expansion sleeve through which the tie rod extends and a cone sleeve positioned around the expansion cone and between the expansion cone and the leading end of the expansion sleeve. The radially outer surfaces of the expansion cone and the cone sleeve each have a different cone angle. Due to the different once angle, when the tie rod is drawn into the expansion sleeve toward the trailing end of the assembly, the part with the smaller cone angle moves in the same direction into the expansion sleeve until it contacts a stop. Subsequently on continued inward movement of the tie rod, both the expansion cone and the cone sleeve are drawn into the leading end of the expansion sleeve and effect an increased expanding action.

A mounting construction (1) for suspended loads (L) having a support carrier part (3, 3′) with a fastener having a pivot element socket (4) and having an associated pivot nut (5), pivotably fixable therein in at least one pivot plane (1a, 1b), having an inside thread (6). The pivot element socket (4) has a guide slot (8) along a first pivot plane (1b) having a width (B) corresponding to a cross-section of a threaded rod (7) capable of passing therethrough. The pivot nut (5) and a marginal zone (9) arranged on both sides of the guide slot (8) each form guide surfaces (10a, 10b) that are saddle shaped.

A quick mounting nut (2) movable, at least partially, without being rotated, axially to a threaded bolt (1), with a springing wire clip (4) being located in a nut housing (5) with a continuous coaxial opening (6), with the wire clip (4) at least partially engaging in a bolt thread (3) and having two legs (8, 8′) which spring relative to one another, with the opening (6) having an inner cone (7) which narrows radially from an axial neutral position of the wire clip (4) and with the wire clip (4) being movable axially to a limited extent and contacting at least partially inside the inner cone (7) in its locking position.

An attachment assembly formed of an anchor bolt (1) and an expansion wedge (2) with the anchor bolt having an outside surface (4) at its leading end in the setting direction and widening in a wedge-like manner. The expansion wedge (2) can be displaced axially along the wedge-like outside surface (4) for effecting expansion of the attachment assembly. At its trailing end (6), the anchor bolt (1) has a flange-like engagement part (5) for applying a load to a receiving material into which the attachment assembly is expanded. The engagement part (5) has a throughbore (3) through which the expansion wedge (2) extends and is secured in a preassembled state. The expansion wedge (2) has a trailing end section (14) extending rearwardly from the engagement part (5) in the preassembled state so that in the expanded state the expansion wedge is held in a press fit in the throughbore (3).
摘要:
An anchor member assembly is made up of an anchor bolt and an expansion wedge. The assembly can be anchored in a borehole in a receiving material by inserting the assembly and then displacing the expansion wedge relative to a wedge surface on the anchor bolt. At its trailing end, the anchor bolt has an axially extending outwardly flaring head section forming at least a part of a conical surface. The head section can be driven by hammer blows into a wooden member. Initially, the anchor bolt and expansion wedge are in detachable engagement until the head section is driven into the wooden member. Subsequently, as the expansion wedge is axially displaced relative to the anchor bolt, the engagement between them is released and the anchor member assembly is secured in the receiving material.
