Definitions
- the invention relates to a dowel device for fastening insulating material with the features of the preamble of claim 1, a tool contact piece for a driving tool with the features of claim 14 and a driving tool with such a tool contact piece.
- the thermal insulation of buildings can no longer be thought of in new buildings today.
- the actual thermal insulation is performed by the insulation, for the turn regularly insulation boards, such as polystyrene, are used. These are fastened to the wall surface of the respective building. Subsequently, a flush and an outer plaster layer are applied.
- the insulation boards are often fastened with the help of dowels to the wall surface.
- a dowel regularly has a pressure plate and a hollow shaft, wherein the hollow shaft is pierced so in the little solid insulation, that the pressure plate rests on the surface of the insulating material.
- a fastener which may be about a nail or a mounting bracket, introduced into the hollow shaft.
- the hollow shaft leads the fastener through the insulating material, wherein the fastener is longer than the hollow shaft and penetrates into the wall surface. In this case, the entire dowel is retracted so far with the fastener that the pressure plate of the dowel is flush with the insulation surface.
- the fastener is regularly applied by a pneumatic operated driving tool, such as a nail or bolt gun.
- the US 2011/0222987 Al shows such a dowel for fixing insulating material with a pressure plate and a hollow shaft.
- a problem with the known from the prior art plugs for fixing insulation material is that the use of the driving tool requires a certain fine adjustment by the operator, the thereby occurring interruption of otherwise speedy handling represents a significant time factor at work.
- the setting of the fastener and further movement to the next dowel is required as an intermediate step, the fine adjustment of the relatively heavy driving tool to meet with the fastener not only the relatively narrow hollow shaft, but also the fastener straight and not be able to bring angled into the hollow shaft. This step is tiring for the operator as well as error prone and time consuming.
- the problem of the invention is therefore to be able to ensure a rapid and error-free attachment of the anchor with the driving tool.
- a centering effect can be achieved with a corresponding mating contour on a tool contact piece of a driving tool, so that upon pressing the driving tool and especially of the tool contact piece against the pressure plate an automatic fine adjustment the alignment of the driving tool is achieved.
- the tool contact piece from which at last the fastener off and enters the hollow shaft, slips and slides by the gentle pressure all by itself in a position in which the positive connection between the centering and the corresponding mating contour is formed on the tool contact piece and so in that the fastening element can be placed exactly in the hollow shaft in a direction which corresponds exactly to the course of the hollow shaft in the insulating material.
- the preferred embodiment according to claim 4 provides extension-like elevations of the centering surface. In this way, a particularly effective positive locking is ensured, in which a slipping or slipping out after the positive connection has already been established can be effectively avoided.
- the self-centering effect of the centering surface is particularly effectively reinforced.
- the fasteners for the present dowels are regularly made of metal, which they can form thermal bridges between the wall surface and the exterior plaster. It is obvious that thereby the Wännedämm Anlagen the attached by the dowels insulation material is somewhat limited. In order to avoid or prevent this effect, cover plugs can be provided, which fill the channel, through which the fastener was introduced, again heat-insulating between the fastener and the outer plaster after introducing the fastener. It is now interesting, as proposed in claim 8, to use the centering surface on the upper side of the pressure plate also for receiving the Abdeckstopfens. In this way, both a correct and centered alignment of the Abdeckstopfens is achieved as well as prevents the Abdeckstopfen between the attachment to the centering surface and the application of the flush layer of the pressure plate drops.
- claims 9 to 12 in turn further develop the design of the Abdeckstopfens to the effect that the resulting by the introduction of the fastener into the hollow shaft clamping position of the pressure plate, whereby a certain deformation in the sense of contraction arises, does not lead to a detachment of the Abdeckstopfens.
- the Abdeckstopfen should be formed so that in a rest position different spaces between the pressure plate and the Abdeckstopfen are present in which can then contract in the clamping position of the pressure plate, without driving the Abdeckstopfen from the centering.
- the preferred embodiment according to claim 13, in turn, provides locking elements on the Abdeckstopfen, with which a particularly reliable connection between the Abdeckstopfen and the pressure plate can be made.
- the Fig. 1 to 3 each show a proposed dowel device for fixing insulation.
- the dowel devices shown serve in particular to attach the insulating material to a wall surface, such as a building.
- Consistent with those in the Fig. 1 to 3 illustrated dowel devices each have a pressure plate 1 and a hollow shaft 2.
- the pressure plate 1 and the hollow shaft 2 can be configured in one piece as well as in several parts.
- an opening 4 for introducing a fastening element 2as is provided in the hollow shaft 2.
- a fastening element 2a can be, for example, a nail, a bolt or a fastening clip.
- the opening 4 is arranged centrally to the pressure plate 1.
- the proposed dowel devices of Fig. 1 to 3 are now characterized in that the pressure plate 1 has a formscblussruinede, uneven centering surface 5 from the top 3.
- a form gleichInstitut füre, uneven centering surface 5 in this sense is a surface with elevations and in any case thereby formed between the elevations depressions.
- the proposed pressure plate 1 also has a top surface 7 on the upper side 3, wherein the centering surface 5 is disposed opposite the top surface 7 at least partially recessed.
- the centering surface 5 is form-locking capability in the sense that it is basically suitable for entering a positive locking with one or more corresponding counter contours.
- a mating contour may be that of a tool contact piece 29, wherein such a tool contact piece 29 can likewise be sunk relative to the top surface 7 due to the positive connection with the centering surface 5.
- the positive-locking centering surface 5 is adapted to enter into positive engagement with respect to a translational movement in the radial direction relative to the pressure plate 1, wherein the radial direction is to be understood relative to a longitudinal axis 6 of the hollow shaft 2.
- the positive locking ensures a predefined position of the corresponding mating contour on the upper side 3 of the pressure plate 1.
- the centering surface 5 preferably prevents a rotational movement about the longitudinal axis 6 as a result of its positive locking. Alternatively, it may also be preferred for the centering surface 5 to allow such a rotational movement during this positive locking. Next is particularly preferred, as in the Fig. 1 to 3 illustrated that the centering surface 5 is circular.
- the centering surface 5 is surrounded by the top surface 7 at the top 3 of the pressure plate 1.
- the top surface 7 does not necessarily completely enclose the centering surface 5. Under the top surface 7 of that part of the top 3 of the pressure plate 1 can be understood, which does not belong to the centering surface 5.
- top surface plate openings 8 and plate nubs 9 has for better connection with the flush layer, which may consist of gypsum about.
- the top surface 7 may preferably be convex.
- the centering surface 5 is arranged around the opening 4, wherein it is further preferred that the centering surface 5 has a rotational symmetry about the opening 4.
- the axis of rotation is again the longitudinal axis 6 of the hollow shaft.
- Fig. 1 to 3 all three embodiments of Fig. 1 to 3 is common that the centering surface 5 has at least one stretch-like elevation 10a-c.
- centering surfaces 5 of the first and the third embodiment each have four or twelve track-like elevations 10a, c, which, starting from the opening 4 in the radial direction - again with respect to the longitudinal axis 6 - extend.
- a positive connection with these centering surfaces 5 prevents rotation about the longitudinal axis 6.
- the number and raster of the distance-like elevations 10a, c are preferably selected such that only a small rotation of a mating contour, in particular a tool contact piece 29, is required to allow positive engagement with the centering surface 5 and thus engagement.
- the centering surface 5 of the second embodiment has a track-like elevation 10b, which extends in a circular manner and in particular concentrically with the opening 4.
- a positive connection with a centering surface 5 with such a distance-like elevation 10b permits rotation about the longitudinal axis 6.
- the oblique flanks 10b extend in a circular manner and concentrically with the opening 4, analogously to the strip-like elevations 10b.
- the height 12 of the track-like elevation 10c is preferably between 2.5 mm and 3 mm.
- the comb 13 of the stretch-like elevation has a preferred width of between 0.25 mm and 0.3 mm.
- the radially inner ends of the strip-like elevations 10c form a circle with a preferred diameter between 10 mm and 11 mm as measured from the center of the opening 4, corresponding to the circle formed by the radially outer ends of the strip-like elevations 10c has a preferred diameter between 24 mm and 25 mm.
- the distance-like elevations 10c widen at its base end preferably in such a way that the foot width 14 at the radially inner end between 2.2 mm and 2.7 mm and at the radially outer end between 6.1 mm and 6.5 mm. Accordingly, the angle spanned by the inclined flanks 11c increases a preferred value between 40 ° and 50 ° at the inner flank angle 15a to a preferred value between 90 ° and 100 ° at the outer flank angle 15b.
- the centering surface has 5 Verrastungspapern 16 and in particular Verrastungsdruchbrüche 16a.
- Verrastungs Tebrüchen continuous openings from the top 3 of the pressure plate 1 to the bottom 17 of the pressure plate. 1
- a preferred embodiment is characterized in that the hollow shaft 2 a tip 18 or a bevel 19 - shown in an alternative detailed view of Fig. 4 - having.
- the hollow shaft 2 can be particularly simple and also bring by hand in the insulation material.
- the tip 18 can also - as in the Fig. 4 shown - closed and be adapted to be broken when introducing the fastener 2aes.
- the anchor device has a cover stopper 20.
- this se separate Abdeckstopfen 20 can be integrally but clipped attached to the pressure plate 1, which is particularly suitable for a production of the Abdeckstopfens 20 as a single injection molded part together with the pressure plate 1 and the hollow shaft 2.
- This Abdeckstopfen 20 is adapted to be received by the centering surface 5, so that a plug plate 21 of the Abdeckstopfens 20 is flush with the top surface 7.
- the Abdeckstopfen 20 thus closes the gap formed by the recessed centering surface 5 by the plug plate 21 continues the top surface 7 in its even or convex shape evenly.
- the Abdeckstopfen 20 forms a positive connection with the centering surface 5 and in particular by a plug contour 22 on a - based on the recorded by the centering surface 5 - bottom 23 of the plug plate 21st
- a fastener 2as leads according to its purpose to the fact that the pressure plate 1 is pressed against the insulating material. However, this also causes a deformation of the pressure plate 1, and in particular so that the pressure plate 1 is contracted in the direction of the opening 4 and tends to fold up in the direction away from the insulating material direction.
- Various constructional measures are now preferred in order to prevent a detachment of the covering plug 20 caused thereby from the centering surface 5.
- the plug plate 21 has a smaller diameter than the centering surface 5. This is to be understood not only in the sense that the plug plate 21 - and thus the Abdeckstopfen 20 - can be absorbed by the centering surface 5, which has already been determined. Rather, the diameter of the plug plate 21 is smaller by such a degree that even after a reduction in the diameter of the centering 5 after insertion of the fastener 2as in the hollow shaft 2 still a gap between the plug plate 20 and the outer edge of the centering surface 5 remains.
- the plug plate 21 has on its underside 23 along its outer edge 24 a circumferential bevel 25. This is especially in the detail of the Fig. 4 to recognize.
- the circumferential bevel 25 leaves room for an increase or a folding up of the centering surface 5 in the region of the outer edge of the centering surface 5, without the cover plug 20 being pressed out of the centering surface 5.
- the plug plate 21 has on its underside 23 a protruding rim 26 with a tapered jacket.
- This collar 26 has a tapered jacket in the sense that the profile of the collar 26 tapers in a section along the longitudinal axis 6 of the hollow pin 2 as it extends from the bottom 23. The imaginary envelope of the ring 26 thus tapers conically in the direction of the insulating material.
- the introduction of the fastening element 2as causes a deformation of the pressure plate 1.
- the pressure plate 1 can be brought by introducing the fastener 2as in the opening 4 from a rest position into a clamping position.
- the clamping position thus corresponds to the deformed state.
- the centering surface 5 has a circumferential funnel cone wall 27, so that when receiving the Abdeckstopfens 20 by the centering surface 5 in the rest position, a clearance between the funnel cone wall 27 and the rim 26 is present.
- the funnel cone wall 27 can also change their shape, in particular can contract without the rim 26 and thus the Abdeckstopfen 20 to press out of the centering 5, just because of in the rest position existing space in the clamping position through the funnel cone wall 27 can be exploited.
- the ring 26 has locking elements 28 which project radially outward from the jacket.
- the locking elements 28 form in a section along the longitudinal axis 6 is not just a tapered profile, but on the contrary have radially outward. It is preferred that the locking elements 28 are adapted for engagement in the Verrastungsingn 16 and in particular in the Verrastungs trimbrüche 16a. This is the detail of the Fig. 4 displayed.
- the Fig. 5 shows a proposed tool contact piece 29 for a driving tool 30, here for example a nail device 30a, wherein the tool contact piece 29 has a front-side mating contour 31 for positive engagement in the centering surface 5 of a proposed dowel device.
- the Fig. 5 also shows the Eintreibtechnikmaschine 30 itself, here the nail device 30a, with several proposed tool contact pieces 29.
- the tool contact pieces 29 may be provided for a replaceable attachment to the driving tool 30, which is particularly preferred if for different embodiments proposed dowel devices different centering 5 and thus also contours 31 are provided.
