- the fastening sleeve has at least one, preferably a plurality, adhesive outlet openings, through the adhesive, which in the
- the Mounting sleeve is inserted, exits.
- the escaping adhesive glues the Mounting sleeve with the core and / or one or both cover plates of the lightweight board.
- the adhesive outlet openings can be arranged at different locations of the fastening sleeve in order to effect a targeted adhesive outlet as enumerated, for example, in the core and / or on one or both cover plates of the lightweight building panel.
- the adhesive is usually introduced through the screw-in opening of the fastening sleeve.
- connection insert mounting sleeve Such, designated as a connection insert mounting sleeve is known from international patent application WO 2006/106 131 A1.
- the known fastening sleeve is double-walled by an attached outer tube, which is not important for the present invention, but also not excluded.
- a screw can be screwed with preferably self-tapping thread in the adhesive in the mounting sleeve.
- the glued with the lightweight board mounting sleeve is the screwed
- Screw stable hold The glued into the lightweight panel mounting sleeve forms a mounting or screw point.
- attachment or screw point is not to be understood in the sense of a mathematical point, but as a place to a stable mounting option on the lightweight board.
- the object of the invention is to propose a possibility that facilitates the insertion of a screw in a mounting sleeve, which is glued into a lightweight panel.
- the glued with the lightweight board mounting sleeve of the inventive arrangement has an adhesive-free hole for screwing the screw.
- the glue-free hole opens into the screw-in opening of the fastening sleeve, by which is meant that an opening of the adhesive-free hole is accessible from an outside of the lightweight board, so that the screw can be screwed.
- the glue-free hole is not made by drilling the cured adhesive, but is held free of adhesive when the adhesive is placed in the mounting sleeve.
- a core may be arranged in the fastening sleeve or the adhesive is introduced with an injection nozzle, which is inserted so far into the mounting sleeve, that the desired hole is formed in the adhesive.
- the inventive method according to claim 6 provides, as already described, that in the mounting sleeve, a hole for screwing the screw is kept free of adhesive.
- screw is here to be understood as a synonym for a component which has an external thread.
- Adhesive is to be understood as meaning a flowable, in particular pasty and hardening, one- or multi-component mass which is the substance of the invention
- An embodiment of the invention provides that the adhesive-free hole in the radial direction extends to a wall of the fastening sleeve. This means that there is no adhesive in the area of the hole, the screw is directly in the wall of the
- Screwed fastening sleeve Screwed fastening sleeve.
- the glue-free hole can also be over part of his
- the screw engages directly into the wall of the fastening sleeve and it allows a large screw diameter in relation to a diameter of the fastening sleeve.
- Another embodiment of the invention provides that is located in the region of the hole adhesive on an inner side of a wall of the fastening sleeve.
- the glue-free hole in the mounting sleeve forms a kind of "core hole" for the
- Thread of the screw also extend into the mounting sleeve, so cut into the wall of the mounting sleeve.
- an embodiment of the method according to the invention provides that the adhesive is introduced with an injection nozzle through the screw-in opening into the fastening sleeve.
- the injection nozzle is inserted a little way into the mounting sleeve and thereby keeps a hole in the as desired
- the injection nozzle has a tube which may be cylindrical or tapering toward an exit opening.
- the injection nozzle can also be formed, for example, by a so-called static mixer.
- the illustrated in Figure 1, generally designated 1 inventive arrangement has a lightweight panel 2, in which a mounting sleeve 3 is inserted from plastic.
- the lightweight board 2 has two cover plates 4, 5, between which a
- Core 6 is arranged, which connects the two cover plates 4, 5 to the lightweight panel 2.
- the core 6 has honeycomb, the lightweight panel 2 can therefore as well
- the cover plates 4, 5 may for example consist of wood or plastic, the core 6 may comprise honeycombs of cardboard, for example.
- a hole 7 is drilled through one of the two cover plates 4 into the core 6 of the lightweight board 2.
- the mounting sleeve 3 is inserted. In the exemplary embodiment, it is flush with the pierced cover plate 4, but this is not mandatory for the invention.
- Mounting sleeve 3 can also be recessed in the cover plate 4 or protrude from the cover plate 4, in particular there have a flange with which the mounting sleeve 3 rests on an outer side of the cover plate 4 (not shown).
- a located in the pierced cover plate 4 of the lightweight board 2 front end of the mounting sleeve 3 is open, the open end forms a screw 8, through which a screw, not shown (or other fastener) with self-tapping thread in the mounting sleeve 3 can be screwed.
- the fastening sleeve 3 In its peripheral wall, the fastening sleeve 3 has adhesive outlet openings 9, 10, which are arranged in the region of the perforated cover plate 4 and the core 6 of the lightweight building board 2. Also the screw-in opening 8 distant front end of
- Mounting sleeve 3 is open and provided with slots as adhesive outlet openings 1 1. Through the screw 8, adhesive 12 is introduced into the mounting sleeve 3, after the mounting sleeve 3 has been inserted into the hole 7 in the lightweight panel 2. The adhesive 12 passes through the adhesive outlet openings 9, 10,
- the mounting sleeve 3 is shown in Figure 2.
- the adhesive can generally flowable, preferably pasty and curing compounds are used, which connect the mounting sleeve 3 cohesively to the core 6 and the cover plates 4, 5, the lightweight board 2. After curing, the adhesive 12 joins the
- Mounting sleeve 3 stable with the lightweight panel 1, so that a not shown, screwed into the mounting sleeve 3 screw is held stably in the lightweight panel 2.
- the fastening sleeve 3 has an adhesive-free hole 13 (FIG. 2) which opens into the screw-in opening 8 of the fastening sleeve 3, ie the adhesive-free hole 13 is open at the screw-in opening 8 of the fastening sleeve 3.
- the adhesive-free hole 13 is kept free of adhesive during the introduction of the adhesive 12. This is done, for example, as shown in Figure 1 by introducing the adhesive 12 through an injection nozzle 14 which is sealingly placed on the front end of the mounting sleeve 3, which has the screw 8.
- the injection nozzle 14 is sealingly placed on the pierced cover plate 4 of the lightweight panel 2.
- the injection nozzle 14 projects, as seen in Figure 1, into the mounting sleeve 3 and thereby forms the adhesive-free hole 13 shown in Figure 2 in the adhesive 12 in the mounting sleeve 3.
- the adhesive-free hole 13 allows screwing a screw, not shown after curing of the Adhesive 12 without pre-drilling.
- the adhesive-free hole 13 may be encased by adhesive. This is the case when a diameter of the part of the injection nozzle 14, which projects into the fastening sleeve 3, has a smaller diameter than corresponds to an inner diameter of the fastening sleeve 3.
- the injection nozzle 14 may also be formed by a so-called. Static mixer.
- the injection nozzle 14 is not necessarily for the production, ie shaping of the adhesive-free hole 13 in the adhesive 12, the formation of the adhesive-free hole 13 is also possible in other ways, for example by means of a core (not shown).
