The present invention relates to an arrangement for, in particular distanced, fastening at least one insulating panel to a building, wherein the arrangement has at least one fastening device and at least one dowel, wherein the fastening device at least one, in the direction of a longitudinal axis extending shaft with one, in the direction of the longitudinal axis extending passage opening for passing a fastening bolt, in particular a screw, and wherein on an outer side of the shaft at least one projecting from the outside of the shaft holding web for engaging the fastening device is arranged in the insulating board.
Generic arrangements are z. B. from EP 0 811 773 B1 and AT 407 539 B known. In the generic arrangements shown there are the fasteners and the dowel two separate from the outset of separate components, which exclusively in the assembly by means of a fastening bolt such. B. a screw are indirectly connected to each other via the fastening bolt. This has the advantage that, after the fastening device is anchored by means of fastening bolts and dowels in the wall, still an adjustment of the fastening device z. B. is possible to adjust the position of the insulation panels on the building. In the generic arrangements disclosed in the abovementioned documents, first the fastening device is screwed into the insulating material plate. Following this, a hole is drilled in the wall through the passage opening in the shank of the fastening device. When the hole is finished, the fixing bolt together with the dowel is passed through the passage opening in the shaft and inserted into the drilled hole in the wall. Then the fastening bolt is tightened and it can still one

Fine adjustment done by turning the fastening device. In order to achieve the intended for a sufficiently strong attachment of the anchor in the wall setting depth, the person performing the fastening operation must use the dowel and fastening device sufficiently deep into the hole drilled in the wall. The setting depth of the anchor is thus dependent on the care of the operating personnel, which may prove to be a disadvantage in sloppy execution.
The object of the invention is to propose an improvement here.
The invention provides for this purpose that the dowel, preferably in an end region or directly at one end of the passage opening, by means of at least one, at least in one direction parallel to the longitudinal axis of the shaft acting longitudinal stop, preferably positively, on the shaft, preferably non-destructive, releasably supported ,
According to the invention, it is thus provided that the plug is supported on the wall-side end of the shank, preferably in the assembly position, by means of a longitudinal stop. As a result, the dowel is automatically inserted from the shank of the fastening device in the already drilled hole in the wall when inserting the fastening device in the insulation board. As a result, the desired setting depth of the anchor in the drilled hole in the wall is automatically achieved. The risk of incorrect operation is minimized or excluded. Furthermore, the invention has the advantage that during assembly a step can be omitted. So it is sufficient for setting the arrangement according to the invention, first to drill a corresponding hole in the wall. For this purpose, standard drill can be used, which is another advantage of the invention. Subsequently, the arrangement, ie fastening means including dowels by means of the retaining webs of the fastening device in the da mm fabric plate is arranged. Thereafter, the fastening bolt, which may also be pre-assembled, be secured in the dowel. The fine adjustment is then possible, as in the prior art. Arrangements according to the invention are preferably used for the distanced fastening of at least one insulating panel to a building or a wall, ceiling or the like, but they can also be used to fasten the insulating panel adjacent the building or a wall, ceiling or the like.
In order to achieve the desired effect, it is already sufficient if the dowel is exclusively supported on the longitudinal stop in a direction parallel to the longitudinal axis of the shaft on this, so it is already sufficient if the dowel supported only in one direction parallel to the longitudinal axis and otherwise not attached to the fastening device.
In this simplest embodiment, it is not supported on the fastening device in other directions or otherwise secured, but rather in at least one direction, preferably non-destructive, detachable. The dowel does not need to be additionally fastened in any other way apart from the support in one direction parallel to the longitudinal axis of the shaft on the shaft or on the fastening device. The longitudinal stop can be located directly at one end of the passage opening or at one end of the shaft. In mounting position, this is the wall facing the end of the fastening device. But it may also be beneficial not to provide the longitudinal stop directly at this end but in an end region. This end region expediently extends between 10 and 40 mm, preferably between 25 and 35 mm, from said end of the passage opening or of the shaft. As a result, an overlap region between dowel and shank can be made available. By such an overlap region is achieved on the one hand, that the dowel is securely guided by the shaft when introduced into the wellbore. On the other hand, a sealing effect can be achieved by the overlap region, which permanently prevents damage or corrosion of the fastening bolt.
In order to screw the dowels into the borehole in the wall by means of rotation of the shaft of the fastening device, preferred embodiments of the invention provide that the dowel additionally, preferably in the end region or directly at the end of the passage opening, by means of at least one, at least in one tangential direction of rotation about the longitudinal axis of the shaft around acting rotation stop, preferably positively, on the shaft, preferably non-destructive, releasably supported. The rotation stopper causes, when the fastener or its shaft is rotated in a rotational direction about the longitudinal axis of the shaft around, the dowel also performs such a rotation. The rotation stops can be formed for this purpose in various ways. It is conceivable z. B. a pin groove engagement or a toothing or the like. Even with these embodiments, dowels and shank of the fastening device, apart from rotation and longitudinal stop loose, so not be further connected to each other. For completeness, it should be noted that, of course, several longitudinal and / or rotation stops can be provided.
In other embodiments of the invention may also be provided that the dowel, preferably in an end region or directly at one end of the passage opening, is arranged by means of a predetermined breaking point detachable shaft. As a result, the dowel is on the one hand usually no longer destructively solvable but solvable only by loosening the predetermined breaking point, but on the other hand it is achieved that the dowel is captively fixed to the shaft or on the fastening device.
In these variants, it is thus provided that the dowel is preassembled or fastened to the fastening device with a predetermined breaking point, so to speak. This also reduces the number of parts to be brought to the site. Due to the predetermined breaking point between the shank of the fastening device and the dowel, it is then possible to detach the dowel from the shank and thus from the fastening device in order to be able to make the adjustment known per se in the prior art. In this context, a predetermined breaking point is very generally understood to mean a constructive or mechanical or physical measure which ensures that, in the event of a corresponding application of force and / or torque, the plug first releases itself from the shaft in the area of the predetermined breaking point, before it is replaced elsewhere Dowel or comes at the fastening device to a detachment or a break. It is thus a deliberately trained vulnerability, which can be selectively solved under correspondingly pre-given force and / or Drehmomentbeaufschlagungen. The predetermined breaking point can form both the longitudinal stop and the rotational stop or be integrated in this. However, it is also conceivable to additionally provide the predetermined breaking point, preferably at another location.
Arrangements according to the invention can be used for fastening inherently stiff insulating panels z. B. made of polystyrene, but just as well for the attachment of not rigid or softer insulation boards z. B. be used from wood, mineral or glass wool.
In a first type of embodiment, the predetermined breaking point may have at least one, preferably locally limited, material weakening or be designed as such. Such a material weakening may, for. B. as, preferably locally limited, material thinning be formed. In particular, in these embodiments of the predetermined breaking point of the anchor can be integrally formed on the shaft.
On the other hand, other embodiments of a predetermined breaking point can provide for the predetermined breaking point to have at least one material-terminating element which can be broken away when a force limit value is exceeded, or is embodied as such. Instead of the Material-schlusseiementes or in addition, even when exceeding the force limit wegbrechbare or deformable interlocking elements as predetermined breaking point * * ι II ϊ • * * * in the · · «« · ► * * · * j * * · 1 or as part serve it. Furthermore, it is e.g. also conceivable to provide a frictional engagement element as a predetermined breaking point or as part thereof, which is released only when a force limit value is exceeded, so that the dowel is separated from the shaft. Of course, combinations of all the previously mentioned embodiments are conceivable.
In the variants mentioned can be provided that the fastening device and the dowel are initially made as separate components. The breaking point can then z. B. by gluing or welding or positive and / or frictional joining together of dowels and fastening device are formed together.
Furthermore, z. B. be provided that the predetermined breaking point by means of a rotational movement about the longitudinal axis of the shank sheared off and / or by pulling parallel to the longitudinal axis of the shaft is tearable.
Preferably, the fastening device and / or the dowel are made of, preferably the same, plastic Here is z. B. the injection molding or the production of an injection molded part. In the embodiments of the invention, in which the dowel is integrally formed on the shaft, the arrangement of these two parts can be produced in a single injection molding process.
To the fastening device or its retaining webs in the insulation board einbrin gene, preferably, to be able to, is conveniently provided that on or in the shaft, preferably at its end remote from the plug end or end portion, a connecting piece for preferably positive, connecting a rotary tool is arranged for pushing and / or turning the fastening device. These connecting pieces, which are provided at the end or end region of the shaft facing away from the wall in the assembly position, can also be configured in many different ways. You can include a longitudinal and / or rotation stop. Examples are polygonal interventions, groove and web interventions, threads or the like. The end region facing away from the dowel, in which the rotary tool can be arranged, can be several centimeters long.
Further features and details of preferred embodiments of the invention will be explained by way of example in the following description of the figures. They show: • · «c

Fig. 1 Fig. 2 Fig. 3 Fig. 4 and 5 Fig. 6 Fig. 7 and 8 Fig. 9 shows a first embodiment according to the invention in a perspective external view, wherein the dowel is still attached by means of the predetermined breaking point on the shaft. shows the same embodiment, wherein, however, the dowel has been solved at the predetermined breaking point of the fastening device; shows a longitudinal section through the Ausführungsbeispiet like, Figures 1 and 2. show detailed views of alternatives of the design of the predetermined breaking point; a further embodiment of the invention in a longitudinal section, in which the dowel is supported exclusively by means of a longitudinal stop on the shaft;
Sketches for variants, as in addition to the longitudinal stop a rotation stop can be provided and the dowel end of another embodiment of an arrangement according to the invention.
In Fig. 1 is a perspective outside view of a first arrangement according to the invention is shown. The fastening device 1 initially has the shaft 4. In this embodiment, two holding webs 8 are mounted in this embodiment, with which the fastening device 1 can engage or cut into the insulation board. In the embodiment shown, the holding webs 8 are each formed as a screw-like circumferential belt. The helical circumferential band can also be referred to as a helix. It serves to screw the fastening device helically in the insulation board can. All this purpose fulfilling forms of helical circumferential bands are conceivable. The helical circumferential band or the helix may be continuous or interrupted. You can rotate around less or more than 360 ° around the shaft. Gradient and radius can be different, z. B. adapted to the respective insulation board, be formed. Examples of possible values of the slope 25 and the maximum radius 24 are given below with reference to another embodiment. However, these preferred values generally apply to all design variants. The holding webs 8 are arranged on the outer side 7 of the shaft 4 and project from the latter to the outside. The number and size or the radius of these retaining webs 8 as well as the pitch of the helical surfaces can, as I said, vary. Due to their design as a screw-like revolving band or coil, the holding webs 8 shown here, as i · ..!
Set out screw-like cut or screwed into the insulation board and be unscrewed from this again. This also makes it possible to adjust the distance between the insulation board and the building wall by turning the shaft 4. Thus, when turning the shaft, the distance between the insulation board and wall or the building and not the distance between the shaft 4 and the wall of the building changes, preferred embodiments of the invention, as illustrated various embodiments shown here, favorably at least one on or arranged in the shaft 4 supporting surface 15 for supporting the fastening device 1 on the building or on a wall of the building. This supporting surface 15 is conveniently located at the end 9 of the shaft 4 facing the dowel 2. As shown in the exemplary embodiments shown here, it is preferably provided that the supporting surface 15 surrounds the passage opening 5 in an annular manner. By means of the arrangement according to the invention insulation boards can be mounted on different inclined walls so also on ceilings and floors of a building.
In order to rotate the already sunk in the insulation plate fastening device for Feinjustie-tion of the insulation board on the building, is conveniently provided that on or in the shaft, preferably at its end remote from the plug, a connecting piece for, preferably positive, connecting a rotary tool for turning the fastening device is arranged. When connecting piece 14 may, as in the embodiment shown here z. B. to act a polygonal socket, in which a corresponding outer polygon of a rotary tool is used. Other variants are conceivable, as already stated above.
Fig. 3 shows a longitudinal section through the embodiment like, Figs. 1 and 2. It can be seen here is particularly well, the passage opening 5 in the shaft 4, 9 is attached to the end 9 of the predetermined breaking point 10 of the dowels. Through this passage opening 5, as is well known, in Fig, 3 also shown fastening bolts 6 such. B, a screw to be passed. A correspondingly widened in the radial direction head of the fastening bolt 6 and the screw can abut against corresponding shoulders 16 in the interior of the shaft 4 at this, which makes it possible to press the support surfaces 15 against the wall of the building, not shown here.
In the first embodiment, the dowel 2 is integrally formed on the device 1. It can be z. B. be a one-piece plastic or injection molded part. The predetermined fracture parts 10 are designed in this embodiment according to FIG. 3 as material weakening or concretely as material thinning.
For mounting the arrangement according to the invention shown in Fig. 3, the entire arrangement shown in Fig. 3 is first screwed so far by means of the holding webs 8 in the insulation board, that the anchor 2 exits on the other side of the insulation board again. There it is automatically introduced during insertion of the fastening device 1 in a predrilled hole in the building or its wall until the support surfaces 15 comes to the building wall, not shown here in the area around the pre-drilled hole around the plant. As a result, the intended setting depth of the anchor 2 in the predrilled hole is automatically achieved. Subsequently, the per se known fastening bolt 6 or the screw can be inserted through the through hole 5, so that by corresponding rotational movements of the fastening bolt 6 of these begins to be screwed into the dowel 2. Of course, the fastening bolt 6 can also be arranged in the passage opening from the beginning. The release of the anchor 2 of the inventive device 1 of the first embodiment is done for. B. by applying the fastening bolt 6 in the direction of the longitudinal axis 3 in the direction of the dowel. However, the dowel 2 is particularly preferably sheared off at the predetermined breaking point 10 by a shearing motion from the shank 4 or the fastening device 1. For this purpose, z. B. applied by means of a corresponding, introduced into the fitting 14 a torque tool in the tangential direction of rotation 20 about the longitudinal axis 3 around, which leads to the release of the anchor 2 of the fastening device 1 and its shaft 4. In the event of a corresponding application of force or torque, in any case, the predetermined breaking point 10 breaks, so that the dowel 2 is no longer fastened to the shaft 4 of the fastening device 1. Subsequently, a fine adjustment of the insulation panels, as known per se in the prior art, can now be carried out. For this purpose, the corresponding rotary tool, not shown here again inserted into the connector 14 and the shaft 4 are rotated, which means the holding webs 8, the desired adjustment or adjustment of the distance between the insulation board and the building or its wall.
For the sake of completeness it should be pointed out that the connecting piece 14 can be arranged directly on the end facing away from the plug 13 but also in an end region 22 preferably comprising several centimeters on the shaft 4. The embodiment of the connecting piece 14 can be very different, for. B. in the variants already mentioned, be realized. I:: 9
In the illustrated embodiment like. Fig. 1 to 3 forms the predetermined breaking point 10, at least before breaking up, both a longitudinal stop 19, which supports the dowel in a direction parallel to the longitudinal axis 3, as well as a rotation stop 21, which ensures that upon rotation of the fastening device 1 in tangential direction of rotation 20 around the longitudinal axis 3 around the dowel 2 is rotated. By breaking the predetermined breaking point 10 then the rotational and / or longitudinal stop can also be solved.
As can be seen in Fig. 3, the dowel 2 also extends beyond the predetermined breaking point 10 a little way into the through hole 5 of the shaft 4 inside. This is an example of the fact that it is expediently provided that the dowel 2 and the shaft 4 are preferably designed to overlap in an overlapping region 23. The overlap region 23 provides a seal which prevents liquid or moisture from penetrating into the through-opening 5 so deeply that corrosion of the fastening bolt 6 occurs. The overlapping region 23 arranged in the end region 18 favorably has a length of at least 5 mm, preferably 30 mm or more.
In the embodiment like. 1 to 3 are formed on the shaft 4 two, not immediately adjoining spirals as holding webs 8. Of course, it may also be a continuous or more than two helically circulating belts. The angular range over which the circulating belt rotates is of subordinate importance as long as the helical effect results.
For the sake of completeness, it is pointed out that with the outer side 7 of the shank 4, the outer wall of the shank 4 that is respectively opposite the through-hole 5 is meant.
In the embodiment of the invention shown in FIGS. 1 to 3, the predetermined breaking point is designed as a material weakening or material thinning. 4 shows in an alternative to this, by way of example, how a predetermined breaking point 10 can also be formed. There are no longer the entire fastening device 1 and the entire dowel 2 shown. These can be carried out as in the first embodiment, apart from the changes shown. In the embodiment like. Fig. 4, the predetermined breaking point 10 ineinandergrelfende positive locking elements 12, which allow the dowel 9 to be arranged on the shaft 4 and to secure. The interlocking elements 12 and the predetermined breaking point 10 also form in this embodiment, at least before
Breaking the predetermined breaking point 10, both a longitudinal stop 19 and a rotation stop 21. Again, an overlap region 23 is provided which, as in the other already described embodiment, both achieves a sealing effect and ensures good guidance of the anchor 2 in the shaft 4 , In order to better explain this embodiment, the dowel 2 and the shaft 4 are already separated from each other in the selected representation. On the outer surface of the dowel 2, the interlocking elements 12 arranged there are visible. It may be both depressions and, as shown here, corresponding increases relative to the other outer surface of the anchor 2 in this area. Inside the shaft 4 are like in this embodiment. Fig. 4 on the passage opening 5 surrounding wall, the corresponding recesses or elevations in the wall of the shaft 4 is provided. To visualize this, the shaft 4 is shown in Fig. 4 partially broken. In the illustrated form, the dowel 2 can be inserted into the open end 9, then it comes to locking or engagement of the interlocking elements 12 in the shaft 4 with those in the dowel 2, the dowel 2 is attached to the shaft 4 and arranged and It has formed by the engagement of the corresponding form-locking elements 12 into each other the desired breaking point 10, which, as described above, applied force and / or torque action allows a Wiederloslösung the anchor 2 from the shaft 4 at the desired time. When releasing can be provided both that the form-locking elements 12, preferably elastically deformed. It may just as well be possible for the form-locking elements 12 to break away when the predetermined breaking point 10 is released. Of course, the embodiment shown in Fig. 4 is only an example. Naturally, breakable or deformable positive locking elements 12 for forming a predetermined breaking point 10 may of course also be embodied in many other embodiments.
FIG. 5 shows by way of example an alternative embodiment in which the predetermined breaking point 10 is formed by material-closing elements 11. Again, as shown in Fig. 4, only a section of a corresponding embodiment is shown. The details, not shown, in turn, can be designed as in the variants according to the invention shown first. In Fig. 5 it can be seen how on the dowel 2, an extension 17 is formed, which has a part of the material closure element 11 at its shaft-side end. Also in Fig. 5, the dowel 2 is already solved by the shaft 4 for illustration. In the original position, in which the dowel 2 is arranged by means of the predetermined breaking point 10 on the shaft 4, marked with 11 ends of the extension 17 are fastened to the material marked 11 at the points of the inner wall of the shaft 4. Such a material
End 11 can z. B. by soldering, welding, joint injection molding or gluing can be achieved. In order to see the location of the material closure 11 within the shaft 4, this is also shown partially broken.
Also, the embodiment shown in Fig. 5 a predetermined breaking point 10 in the form of a material closure element 11 is of course only an example. There are also many other variants of this type of embodiment of the invention conceivable. As an alternative to the form-closure elements 12 or material closure elements 11, the Dübe! 2 also be frictionally secured to the shaft 4 to form a predetermined breaking point 10. This can be z. B. can be achieved if the introduced into the end 9 of the through hole 5 end of the dowel 2 has a slightly larger diameter than the through hole, so that the dowel 2 is biased accordingly sitting in the shaft 4, which also has a corresponding predetermined breaking point 10 is formed. For the sake of completeness, reference is also made to the overlapping region 23 with respect to the exemplary embodiment according to FIG. Furthermore, here formed by means of material closing element 11 predetermined breaking point 10, as long as it is not broken, both a longitudinal stopper 19 and a rotation stop 21 between dowels 2 and 4 shaft.
6 shows a further exemplary embodiment of an arrangement according to the invention in a longitudinal section through fastening device 1 and dowel 2, by means of which further preferred embodiments are explained by way of example. In the following, particular attention will be paid to these further features, which have not yet been discussed. Everything else can, as already stated, be executed.
First of all, it is pointed out with reference to this exemplary embodiment that the shoulders 1ό provided in the shaft 4 for supporting a head of the fastening bolt or the screw 6 can also be recessed relatively far in the shaft 4. The distance between these shoulders 16 and the end facing away from the plug 2 end 13 of the shaft 4 or, the fastening device 1 may well be several centimeters. The advantage of such variants is that relatively short, and thus cheap screws or fastening bolts 6 can be used. A correspondingly deep recessed arrangement of the shoulders 16 in the shaft 4 can of course also be realized in the other embodiments, which are shown here.
The maximum radius 24 of the retaining web 8 may, based on the longitudinal axis 3, depending on the used Dämmstoffmaterial very different. Conveniently, the maximum radius 24 is between 5 mm and 150 mm, preferably between 30 mm and 80 mm. Even with the slope 25, so the distance between two adjacent threads can vary greatly depending on the insulating material to be fastened. The slope 25 may, for. B. between 5 mm and 100 mm, preferably between 8 mm and 40 mm. Basically, it is pointed out again that a continuous coil, but also spaced coil sections can be provided as holding webs 8. These can rotate around the shaft 4 as screw-surface-like bands by more or less than 360 °.
In contrast to the embodiments shown and discussed so far no predetermined breaking point but only a longitudinal stop 19 is provided here for connecting plug 2 and shaft 4. This supports the dowel 2 in a direction parallel to the longitudinal axis 3 on the fastening device 1 or on the shaft 4. Otherwise, the dowel 2 is not festgeiegt on the shaft 4 or fastening device 1. However, he is happy in the embodiment shown. Fig. 6 in turn a piece inserted into the dowel-side end portion 18 of the shaft 4 to form the overlap region 23, which in turn has the two aforementioned effects. This means that the longitudinal stops 19 need not necessarily be arranged directly on the dowel or wall-side end 9 of the shaft 4. In the illustrated embodiment like. Fig. 6 can also be rotated in the position shown the dowels 2 and the fastening device 1 in tangential directions of rotation 20 against each other.
The support surfaces 15 for supporting the fastening device 1 on a building wall are also annular in this embodiment and provided on the wall-side end of the fastening device 1 and its shaft 4. It should also be pointed out that in this exemplary embodiment, as is also possible in other variants, in the end region 18, immediately adjacent to the end 9, there is a, preferably funnel-shaped, widened insertion region 26. This allows a simple insertion of the anchor 2 in the shaft 4 until it abuts the longitudinal stop 19. Furthermore, the widened insertion region 26 also causes an enlargement of the supporting surface 15, so that the fastening device 1 fastened to a building wall can transmit greater transverse forces to the wall by means of the supporting surfaces 15.
A first variant is shown very schematically in FIG. 7, in which, in addition to the longitudinal stop 19, a rotational stop 21 can be realized so that the dowel 2 rotates in a tangential direction of rotation 20 with the shaft 4 or the fastening device 1 *. 9 4 Λ * * t · · ·
···· · · * * J ** 13 ........... is rotated. To realize this, a nose 27 is schematically arranged in Fig. 7 on the side walls of the dowel 2, which engages in a corresponding groove 28 in the wall of the shaft 4. Fig. 8 shows an alternative to this. Here longitudinal stop 19 and rotation stop 21 are formed together in the form of a toothing. 7 and 8 it is also pointed out that these are only shown in a highly schematized manner and only show the respective characteristics characteristic of the embodiment, shaft 4 and dowels 2 being shown only in sections and virtually transparent.
Fig. 9 shows an example of a dowel end of a shaft 4 with a dowel 2 arranged thereon, Here is not the dowel 2 in the through hole 5 of the shaft 4 but vice versa, the shaft 4 inserted into a corresponding tubular portion 29 of the dowel 2 to the Form overlap area 23. Again, a dowel 2 on the shaft 4 in a direction parallel to the longitudinal axis 3 abstützender longitudinal stop 19 between the shaft 4 and dowel 2 is formed. The form-locking elements 12 shown here are purely optional. Through them, an additional rotation stop 21 and a type of predetermined breaking point 10 can be achieved. They can basically, as shown in Fig. 4, be formed. But they can also be omitted, so that a pure support by means of longitudinal stop 19 in the direction parallel to the longitudinal axis 3 is realized. For the sake of completeness it should be pointed out that, of course, a preferably funnel-shaped expanding insertion region can also be arranged on the tubular section 29, so that the insertion of the shaft 4 into the tubular section 29 is facilitated. Attention should be drawn here to the fact realized in this embodiment that the support surface 15 provided for supporting on the wall can not necessarily be formed on the shaft 4 but also on the dowel 2, as is the case here. The longitudinal stop 19 may additionally have the effect of a sealing surface. Of course, this also applies to the embodiment like. Fig. 6 and all other variants, such as the z. B. in Figs. 7 and 8 shown.
Basically, it should be noted that the invention can be performed with a variety of plugs. In principle, all known in the prior art anchor shapes are conceivable. It may be plastic or metal dowels, cavity dowels, chemical dowels, etc. Furthermore, it is explicitly pointed out that the individual embodiments and features shown on the basis of the various exemplary embodiments can also be combined in another way in order to produce other forms of arrangements according to the invention. In general, these are only exemplary embodiments, which also already indicate that the invention can of course also be implemented in numerous different variants, which are not explicitly shown here.
