摘要:
An anchoring cartridge for hardenable, multiple component materials consists of an inner cartridge (14) that contains the first component and of an outer cartridge (13) that contains the second component. In order to achieve a better mixture of the components, a mixing element (1) is mounted on the rear end (18) of the outer cartridge (13). The mixing element (1) has several mixing blades linked to a ring-shaped collar (3).

Es wird ein Bohrwerkzeug insbesondere zur Holzbearbeitung vorgeschlagen, welche aus einer hohlzylindrischen Bohrkrone mit stirnseitig angeordneten Schneidelementen besteht. Um den inneren Kernbereich der Bohrkrone wenigstens über eine bestimmte axiale Länge entfernen zu können, befindet sich innerhalb der Bohrkrone ein spezielles Fräsbohrwerkzeug. Hierdurch ist die Herstellung einer ringkanalartigen Bohrung mit endseitigem Bohrloch zur Aufnahme eines Befestigungselements möglich.

Es wird ein Halteelement für die Befestigung von Dämmstoffplatten vorgeschlagen, das aus einem Halteteller (1) mit einem daran angeformten hohlen Schaft (2) und einem mit einem Verankerungsbereich (5) versehenen Nagel (4) besteht. Um eine einfache Schlagmontage und einen Korrosionsschutz für den Nagel (4) zu ermöglichen, ist der Nagel (4) wenigstens mit seinem hinteren Ende in dem hohlen Schaft (2) axial fixiert und im Halteteller (1) eingebettet. Ferner weist der hohle Schaft (2) an seinem vorderen Ende einen Abschnitt (3) mit reduzierter Wandstärke auf, der beim Einschlagen des Halteelementes durch Anlage an der Bohrlochmündung eine Abdichtung bildet.
摘要:
The invention concerns a reagent kit designed to produce elements of synthetic resin for anchoring fixation elements in place by bonding them in multi-cavity plugs. The reagent kit comprises (a) a reagent mixture containing 2,2-bis-[4-(methacryloxyethoxy)phenyl]propane and an optionally unsaturated polyester resin, vinyl resin or acrylic resin or a mixture of these, (b) an accelerator component comprising an organic peroxide and (c) a filler component, the accelerator component (b) being kept separate from the reagent mixture (a) before use.
摘要:
A fixing rod has a shaft (2) with several conical sections (7) mortared into a drill hole (11) in a fastening substrate (10) with a synthetic resin mortar (12). If the diameter of the drill hole (11) is enlarged as a result of crack formation, a tensile force on the fixing rod (1) causes the mortar sheets to expand due to slipping of the fixing rod (1) with respect to the synthetic resin mortar (12). For this purpose, the mortar sheath of the conical sections (7) is of low-friction design, being provided for example with a coating (9), a film or a casing.
摘要:
An expanding fastener has a shaft (4) which at its front end passes into an axially slotted expanding region (6) with a plurality of expanding ridges. The expanding ridges (7) can be expanded over an expanding element (11, 12) which can be driven into the expanding region (6). The expanding element (11) has a cylindrical pin (4) at the rear end of which is an outwardly distortable collar (20). When the expanding fastener is driven in, the collar (20) comes into contact with a rear wall (26) of a rivet chamber and is thereby distorted into an annular ring so that the expanding element (11) is riveted into the rivet chamber and prevented from falling out of the expanding region (6).

An undercutting drill for obtaining a drill hole (5) with conical undercut (4) has a drill shaft (6) connected in an articulated manner through a housing (8) containing a universal joint to a clamping shank (14), the face of the housing (8) facing the drill shaft (6) being provided with a plate (39) having a stopping face (40), the vertical centre-line of which is tilted in relation to the longitudinal axis of the drill shaft (6).
摘要:
A reactive composition for preparing synthetic resin bodies used in destructible multiple-chamber cartridges and a process for anchoring a fastening element to the fastening base by introducing the destructible multiple-chamber cartridges containing the components of a curable adhesive in a drilling in the fastening base. When the fastening element is driven into the hole, the cartridge is destroyed, the synthetic resin components are mixed and harden forming a synthetic resin body. The reactive compound contains between 18 and 25 parts by weight of a pre-activated resin component composed of (A) between 3 and 60 parts by weight of a vinylester epoxy resin, (B) between 28 and 45 parts by weight of one or several ethylenically unsaturated monomeric compounds and (C) between 63 and 3 parts by weight of an unsaturated polyester and if necessary (D) between 10 and 0.1 part by weight of epoxy resin, between 0.4 and 1.2 parts by weight of hardeners and between 40 and 55 parts by weight of fillers.
