摘要:
The aim of the invention is to configure a fixing device (11) with at least one component (17) on a mounting plate (12) in such a way that no permanent damage occurs during a predetermined tightening of the fixing device (11) on the mounting plate (12). To achieve this a retaining part (13) of the fixing device (11) has a shoulder (18) at a point of connection with the mounting plate (12) and a spacer body (14) of said fixing device (11) has a double bush (20) comprising an exterior sleeve (21) and an interior sleeve (22). The position allocation of the two sleeves (21, 22) is carried out in such a way that during the tightening of the fixing device (11), the interior bush (22) comes to rest on the shoulder (18) and the feeding of the mounting plate (12) into the spacer body (14) is limited. The fixing device (11) is preferably designed for use in the automotive industry.

A construction anchor (50) for mounting an object onto a structure of masonry, concrete, metal or the like includes a metal anchoring portion (10) and a plastic cap (30). The anchor (50) is adapted to be inserted, anchoring portion (10) first, into a pre-drilled adhesive (54) filled hole (52). The cap (30) has a flange (32) that is larger than the hole (52) diameter, so that the anchor (50) may be inserted and seated in the hole at a consistent depth. When the adhesive has set, a screw or bolt (58) is inserted through the plastic cap (30) to engage the threads (22) in an internal bore in the anchoring portion (10). The plastic cap (30) serves not only to determine the depth of the anchor (50) in the hole (52), but also to prevent adhesive (54) and other material from entering the threaded interior of the anchor (50) prior to use.

Eine im wesentlichen zylinderförmige Unterlegscheibe weist an einer, einem Bohrloch zugewandten Seite zwei bogenförmige Kanäle 7 auf, welche eine Öffnung 2 mit einer Durchgangsbohrung 3 verbinden. Die Öffnung 2 ist zur Durchführung einer Ankerstange und die Durchgangsbohrung 3 zum Einfüllen einer Mörtelmasse ins Bohrloch ausgebildet. Die Kanäle 7 sind gegenüber dem Bohrloch offen ausgebildet und weisen einen, im wesentlichen halbkreisförmigen, Querschnitt auf, um eine hohe Bruchfestigkeit der Unterlegscheibe sicherzustellen.

Ein Eingussdübel mit einem, über ein temporär fliessfähiges, aushärtbares Befestigungsmittel (2) in einem Sackloch (3) im ersten Festkörper (4) befestigbaren, Befestigungsteil (5) und mit einem radial auskragenden, in einem zeitlich später aushärtenden zweiten Festkörper (6) fliessfähig einbettbaren, Einbettungsteil (7), wobei innerhalb des Einbettungsteils (7) eine konusartig ausgeformte Konushülse (8) vorhanden ist.
摘要:
An adhesively bonded construction anchor (10) for mounting in masonry, concrete, or the like includes an anchoring portion and a cap (40). The anchor is adapted to be inserted, anchoring portion first into a pre-drilled adhesive-filled hole (62). The anchoring portion has a threaded bore (26), which includes an unthreaded close-fit-counterbore portion (28) outward of a threaded portion (26). The cap (40) prevents dust, dirt and adhesive from entering the threaded bore (26), and has an upper surface with a removable central area (54) . When the adhesive has set, holding the construction anchor (10) within the hole (62), the central area (54) is removed, and a screw or bolt (70) is inserted through the hole left by the removal and engaged with the threaded portion (26) of the threaded bore. The unthreaded close-fit-counterbore portion (28) of the threaded bore provides a stretch zone for the screw or bolt (70).
摘要:
The inventive anchor bar (10) consist of two end segments (11, 12). One segment (11) is introduced into a support block (1), the second block (12) being fixed to another element. The segment (11) which can be introduced into the support block is a drilling segment (11) which makes it possible to produce a drill hole (20) in the block (1) without chips. Said drilling segment (11) is arranged in the drill bore (20) without any axial play and preferably embodied in the form of a one-spiral auger.
摘要:
A composition for use as a self-locking agent which comprises an aqueous dispersion comprising a a polyamide powder being insoluble or slightly soluble in water, b an isocyanate compound, c a surfactant and d a water-soluble polyamide which are dissolved or dispersed therein. The composition allows the formation of a polyamide resin layer exhibiting improved smoothness of its surface, the improvement of production efficiency through shortening of the time for heating and melting, and the improvement of the precision in resin coating processing through the prevention of slippage and sagging.
