Abstract: A sleeve (20) for centering fasteners during the assembly of components such as facade elements on the substructure of a building envelope includes a sleeve body (23) and a connection bracket (25). The sleeve body (23) has a plurality of sleeve elements (21, 22) which are grouped around a central center axis A and are spaced apart from each other by gaps running in the sleeve longitudinal direction. At least a first (21) and a second (22) sleeve piece are connected to each other at an axial longitudinal end of the sleeve body (23) by a separable connection bracket (25), preferably the connection bracket is separable via predetermined breaking points. Such a sleeve is used in the construction of facades, wherein it is inserted into a pilot hole of a facade element, the connection bracket is broken off and a fastener is inserted into the sleeve. Driving the fastener centers the fastener in the sleeve and the sleeve is removed from the pilot hole.

Abstract: A fastening arrangement for anchoring facade panel elements includes a substructure on a building shell and a plurality of facade panel elements. The fastening arrangement has an adhesive component and a mechanical securing component. The fastening arrangement is characterized in that per facade panel element, at least two securing straps are provided as mechanical securing components, each having at least two fastening points. At least one fastening point of the two securing straps has a sliding point which uses an oblong hole. Furthermore, the longitudinal extent of this oblong hole defines an axis which is tilted at an angle ? of between 5° and 20° relative to the vertical axis. The fastening arrangement is constructed by preparing the substructure and at least one facade panel element for fastening, attaching the securing straps to the facade element and applying an adhesive component.

Abstract: A self-tapping screw having a boring part and a threaded shaft for fixing a panel-type object to a preferably metallic substructure is provided. The screw is configured in such a way that it produces a through hole in the panel type object, said hole accommodating the shaft with a degree of play and so that it produces a bore in the substructure into which the thread on the shaft cuts a counter-thread. The boring part includes a boring tip that is located eccentrically in relation to the longitudinal axis of the screw. The tip centers the screw during the positioning operation in such a way that the boring part executes a circular displacement about the boring tip, which expands the through hole to the desired size, whereas the bore in the substructure is produced with the diameter of the boring part.

Abstract: A washer (14) and a threaded assembly (22) between a screw (30) and a workpiece (42) are provided. The washer (14) is offset up to an angle (?) with respect to a flat initial state, such that the washer has an insert thickness (De) that is substantially greater than the initial thickness (Da) thereof. The washer (14) is made of a malleable material. The length (Lg) of an unthreaded shank section (40) of the screw (30) is smaller than the sum of the thickness (Dw) of the workpiece (42) and the insert thickness (De) of the washer (14), and essentially not smaller than the sum of the thickness (Dw) of the workpiece (14) and the insert thickness (Da) of the washer (14). When the last thread of the screw (30) leaves the workpiece (42) on being screwed in, the force previously exerted on the washer (14) by the feed of the screw is zero.

The screws (3) that are used include a screw head (4) and a shank (6) provided, at least over a portion of its length, with a thread (5). The screw (3) is screwed in from the side of the metallic substructure (2) and engages, via the shank (6) provided with the thread (5), inside the boards, panels or slats (1) made of wood or of wood materials. An essentially non-threaded shank section (7) is provided between the screw head (4) and a beginning of the thread (5) on the shank (6).

Abstract: A stamped rivet (10) has a head (12), a shaft (14), a circumferential groove formed therein and a shaft end (18). The head is provided with a ring-shaped planar surface (20). The circumferential groove (16) is directly adjacent to the lower side of the head (12). One section (22) of the shaft is conically tapered in an area located between the circumferential groove (16) and the end (18) of the shaft in the direction of the end of the shaft. The axial length (L) of the circumferential groove (16) is greater than a thickness of the sheet metal or the overall thickness of the metal sheets in which the stamp rivet is to be installed. The circumferential groove (16) extends to a longitudinal center (M) of the stamped rivet (10). The length of the tapered section (22) of the shaft (14) corresponds to the axial length (L) of the circumferential groove (16).

Abstract: A stamped rivet (10) for the connection of metal sheets (12, 14) to each other is provided, and includes a shaft (16) with several circumferential ribs (18) located one above another on the shaft (16), a shaft end (20) for pressing through the sheets (12, 14) for connection to each other, and a head (26). An adjacent region (30) to the shaft end (20) has no circumferential ribs and has a diameter smaller than an outside diameter (D) of the circumferential ribs. The stamped rivet (10) is easy to set as the setting device only has to be able to push the stamped rivet (10) through the sheets (12, 14) for connection. Sheet material is then forced by plastic deformation into the circumferential grooves (38) formed between the circumferential ribs (18).

Abstract: A device for installing a stamped rivet into sheet metal is provided having an upper socket in which a stamp can be displaced, a fixed lower socket which is located at a distance from the upper socket and which receives the shaft of the stamped rivet during the stamping-in process, and which also includes a clamping bushing which is elastically pre-tensioned and surrounds the lower socket and protrudes above the lower socket in a direction of the stamp and acts as a support for the sheet metal which is to be joined by or with the stamped rivet. The stamp, lower socket and clamping bushing are configured so that when the rivet is stamped in, a peripheral groove formed in the rivet shaft directly below the head is filled with metal sheet material which is stamped through by the rivet during the fixing process and is initially formed downwardly and then plastically deformed into the groove.

Abstract: A hole-shaping and thread-forming screw (1) has a non-cutting hole-shaping end section (2) that ends in a point, a haft section (4) provided with a thread (3) and an engagement section (5). The non-cutting hole-shaping end section (2) tapers towards its end. The whole screw is made of a stainless material, in particular its end section (2). When the screw (1) is driven in, a hole is haped without cutting into the workpiece (7) and is then threaded by the screw (1) itself.

Abstract: In a screw for fastening sections to a substructure, a shank (2) is provided with a boring portion (4) and a threaded portion (5) as well as a screw head (3). The portion (6) of the shank (2) adjacent to the screw head (3) flares conically toward the screw head (3). On its underside (7) the screw head (3) is provided with projections and/or depressions. During use for fastening sections to a substructure, the section to be fastened is pressed by the conical portion (6) in screwing direction against the fexed substructure (11).

Abstract: A screwdriver adapter (1) is provided with a receiving part (3) having an interior space (5). At the open end of the pot-shaped receiving part (3) there is inserted a nut-shaped element (2) in torsionally rigid and axially secured relationship. Adjoining the tool driving means (6) there is disposed a channel (8), which passes axially through the nut-shaped element (2) and extends as far as the interior space (5) of the receiving part (3). Drive portions broken off by overtorquing a screw in the tool driving means (6) can travel via the channel (8) into the interior space (5) of the receiving part (3), where they can be collected until an emptying process.
