Description

Die Erfindung bezieht sich auf ein profilstabförmiges Tragelement für einen Putzträger, mit mindestens einem, mit mehreren, in Längsrichtung versetzten Haltegliedern für den Putzträger versehenen oder verbindbaren Profilschenkel und mit einem gegenüber der Stützfläche dieses oder dieser Profilschenkel zurückgesetzten Profilteil, das mehrere in Längsrichtung versetzte Aufnahmen für je ein Befestigungselement des Tragelements aufweist, wobei sich die freien Enden der Halteglieder sowie der Befestigungselemente nach entgegengesetzten Richtungen erstrecken. Ein derartiges Tragelement ist beispielsweise durch die DE-U-7101595 bekannt geworden. Seine Aufnahmen zur Befestigung an einer Außenwand sind kreisrunde Ausstanzungen zum Durchstecken einer Schraube oder eines Nagels. Demnach wird also der wandnahe Profilschenkel dieses Tragelements unmittelbar an die Wand od. dgl. angenagelt oder angeschraubt. Damit die Fassade ausreichend hinterlüftet werden kann, muß man den sich senkrecht zur Wand erstreckenden Profilschenkel vergleichsweise groß ausbilden, wodurch dieses Tragelement groß dimensioniert und infolgedessen schwer und unhandlich wird. Es kommt noch hinzu, daß aufgrund des hohen Materialverbrauchs auch die Kosten dieses Tragelements groß sind. Ein weiterer Nachteil wird darin gesehen, daß man die Hinterlüftung über Ausstanzungen an dem sich senkrecht zur Wand erstreckenden Profilschenkel vornimmt und diese Ausstanzungen die Herstellung zusätzlich verteuern. Anderseits ist aber die Querlüftung über solche Ausstanzungen nicht besonders wirkungsvoll.The invention relates to a profiled bar-shaped support element for a plaster base, with at least one profile leg provided or connectable with a plurality of longitudinally offset holding members for the plaster base and with a profile part set back relative to the supporting surface of this or this profile leg, which has several receptacles offset in the longitudinal direction each has a fastening element of the support element, the free ends of the holding members and of the fastening elements extending in opposite directions. Such a support element is known for example from DE-U-7101595. His recordings for attachment to an outer wall are circular cutouts for inserting a screw or a nail. Accordingly, the profile leg of this supporting element near the wall is nailed or screwed directly onto the wall or the like. In order for the facade to be adequately ventilated, the profile leg extending perpendicular to the wall has to be made comparatively large, as a result of which this support element is large and consequently becomes heavy and unwieldy. In addition, due to the high material consumption, the costs of this support element are high. Another disadvantage is seen in the fact that the rear ventilation is carried out via punched holes on the profile leg extending perpendicular to the wall and these punched holes make the production more expensive. On the other hand, however, cross ventilation via such punched-outs is not particularly effective.

Durch die US-A-2 194 055 sind kleine Tragelemente für einen Putzträger bekannt geworden. Sie werden an Vertikalträger angenagelt, die ihrerseits an der zu verkleidenden Wand befestigt sind. Imbiegbare Halteglieder dienen zum Aufstecken und Festhalten des Putzträgers. Hinter dem Putzträger werden Wandtafeln an den Vertikalträgern angebracht. Die Hinterlüftung ist um so effektiver, je breiter man die Vertikalträger ausbildet. Anderseits werden aber die Vertikalträger mit zunehmender Breite schwerer, unhandlicher und teurer, weswegen diese Art der Befestigung eines Putzträgers auch nicht sehr vorteilhaft ist. Es kommt noch hinzu, daß jedes der kleinen Tragelemente einzeln angenagelt werden muß, wodurch ein verhältnismäßig hoher Montageaufwand entsteht. Ein Ausgleich von Wandunebenheiten oder eine Korrektur einer nicht ganz vertikal verlaufenden Wandfläche ist weder mit diesen Tragelementen noch mit den vorstehend beschriebenen möglich.Small supporting elements for a plaster base have become known from US-A-2 194 055. They are nailed to vertical beams, which in turn are attached to the wall to be clad. Bendable holding members are used to attach and hold the plaster base. Wall boards are attached to the vertical beams behind the plaster base. The rear ventilation is the more effective the wider the vertical beams are. On the other hand, however, the vertical beams become heavier, more unwieldy and more expensive with increasing width, which is why this type of attachment of a plaster beam is also not very advantageous. In addition, each of the small support elements must be nailed individually, which results in a relatively high assembly effort. A compensation of unevenness in the wall or a correction of a not completely vertical wall surface is neither possible with these support elements nor with those described above.

Während bei den Tragelementen der US-A-2194055 die Halteglieder nach dem Aufsetzen des Putzträgers umgebogen werden, schlägt eine Variante der DE-U 309 249 vor, auf nagelförmige Halteglieder jeweils eine Federblech-Klemmutter od. dgl. aufzuschieben. Dies stellt im Prinzip eine wirtschaftliche und bei Verwendung geeigneter Klemmuttern od. dgl. auch montagefreundliche Ausgestaltung dar.While in the support elements of US-A-2194055 the holding members are bent after the plaster support has been put on, a variant of DE-U 309 249 proposes to slide a spring plate clamping nut or the like onto each of the nail-shaped holding members. In principle, this represents an economical and, if suitable clamping nuts or the like are used, also an assembly-friendly design.

Die Aufgabe der Erfindung wird nun darin gesehen, ein profilstabförmiges Tragelement der eingangs genannten Art so weiterzubilden, daß die starre Verbindung des Putzträgers mit der Wand vermieden wird und der Putzträger gegenüber der Wand einfach sowie rasch ausgerichtet werden kann, wobei eine gute Hinterlüftung der vorgehängten Fassade mit dem Putzträger gewährleistet sein soll.The object of the invention is now seen in a profile-shaped support element of the type mentioned so that the rigid connection of the plaster base to the wall is avoided and the plaster base can be easily and quickly aligned with the wall, with good rear ventilation of the curtain wall should be guaranteed with the plaster base.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß das profilstabförmige Tragelement gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Weil nunmehr jedes Befestigungselement in Längsrichtung des Tragelements verschiebbar an letzterem gehalten ist, wird die starre Verbindung zwischen dem Putzträger bzw. der vorgehängten Putzfassade und der Wand vermieden, so daß sich bei unterschiedlicher Wärmeausdehnung Risse oder gar stärkere Beschädigungen der Fassade vermeiden lassen. Des weiteren lassen sich die Tragelemente gegenüber der Wand an jedem einzelnen Befestigungselement exakt ausrichten, so daß man Wandunebenheiten und auch schiefe Wände leicht ausgleichen kann. Im übrigen läßt sich der Wandabstand der Tragelemente durch Verwendung entsprechend langer Befestigungselemente reichlich bemessen, so daß man eine gute Hinterlüftung der vorgehängten Fassade erzielt. Dies ist sowohl in Längs- als auch in Querrichtung gleichermaßen möglich, weil die Befestigungselemente in keiner dieser Richtungen einen nennenswerten Strömungswiderstand darstellen. Zweckmäßigerweise handelt es sich bei den Befestigungselementen um Dübei, insbesondere Spreizdübel. Aufgrund des genügend großen Wandabstands vermeidet man auch eine Verrottung und die Brandgefahr wird zumindest stark reduziert.To achieve this object, it is proposed according to the invention that the profiled rod-shaped support element is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim. Because now each fastener is slidably held in the longitudinal direction of the support element, the rigid connection between the plaster base or the curtain wall and the wall is avoided, so that cracks or even greater damage to the facade can be avoided with different thermal expansion. Furthermore, the support elements can be precisely aligned with the wall on each individual fastening element, so that unevenness in the wall and also inclined walls can be easily compensated for. In addition, the wall distance of the support elements can be generously dimensioned by using appropriately long fasteners, so that good ventilation of the curtain wall is achieved. This is equally possible both in the longitudinal and in the transverse direction, because the fastening elements do not represent any appreciable flow resistance in any of these directions. The fastening elements are expediently dowels, in particular expansion dowels. Due to the sufficiently large distance from the wall, rotting is avoided and the risk of fire is at least greatly reduced.

Die Tragelemente kann man, was ihren Querschnitt angeht, verhältnismäßig klein dimensionieren, weil der Wandabstand durch die Länge der Befestigungselemente bestimmt wird. Infolgedessen sind sie relativ leicht, handlich und wegen des geringen Materialverbrauchs auch billig. Als Werkstoff für diese Tragelemente kommen sowohl Aluminium und Stahl als auch andere bekannte, zumindest feuerhemmende und gegen schädliche Umwelteinflüsse geschützte oder schutzfähige Materialien infrage. Man kann sie durch Strangpressen, Extrudieren, Biegen und dgl. herstellen. Wenn man auf bekannte Herstellungsverfahren zurückgreift, so ist die Fertigung problemlos bei guter Festigkeit und Formtreue.The support elements can be dimensioned relatively small in terms of their cross section, because the wall distance is determined by the length of the fastening elements. As a result, they are relatively light, handy and also cheap because of the low material consumption. Both aluminum and steel as well as other known, at least fire-retardant and protected or protectable materials against harmful environmental influences come into consideration as material for these supporting elements. They can be manufactured by extrusion, extrusion, bending and the like. If one uses known manufacturing processes, the manufacturing is easy with good strength and shape retention.

Vorteilhafterweise verwendet man angeformte, beispielsweise ausgestanzte und herausgebogene Halteglieder. Separat gefertigte Halteglieder kann man entweder in entsprechende Ausnehmungen des Tragelements einhängen oder an einen nach oben weisenden Rand anhängen. Zweckmäßigerweise befinden sich an beiden nach außen umgebogenen Schenkelenden eine genügend große Anzahl von Haltegliedern. Der Putzträger läßt sich demnach schnell und sicher befestigen. Umgekehrt kann man auch eine leichte Anpassung an verschiedene Putzträger einfach vornehmen, insbesondere, wenn man abnehmbare Halteglieder vorsieht.It is advantageous to use molded, for example punched out and bent out ne holding links. Separately manufactured holding members can either be hooked into corresponding recesses in the support element or attached to an upward-facing edge. Expediently, a sufficiently large number of holding members are located on both leg ends bent outwards. The plaster base can therefore be attached quickly and safely. Conversely, you can also easily make a slight adjustment to different plaster bases, especially if you provide removable holding members.

Der U-förmige Querschnitt des Tragelements ermöglicht das versenkte Anbringen zumindest der von der Wand abgewandten Anschlagglieder ohne Behinderung des Putzträgers. Im übrigen ergibt sich aus dem Vorstehenden, daß man diese Tragelemente sowohl in vertikaler als auch horizontaler Richtung montieren kann. Eine Montage im Sinne einer Längs- und Querauflattung ist nicht erforderlich. Mit Hilfe der Anschlagglieder und dem Gewinde des Befestigungselements lassen sich, wie gesagt, die Tragelemente in Längsrichtung der Befestigungselemente ausrichten und nach dem Ausrichten festhalten. Dies beeinträchtigt jedoch nicht die Verschiebbarkeit des Tragelements quer zur Längsachse der Befestigungselemente.The U-shaped cross section of the support element enables the recessed attachment of at least the stop members facing away from the wall without obstructing the plaster support. In addition, it follows from the above that these support elements can be mounted both in the vertical and in the horizontal direction. Installation in the sense of longitudinal and transverse lathing is not necessary. With the help of the stop members and the thread of the fastening element, the support elements can, as stated, be aligned in the longitudinal direction of the fastening elements and held in place after the alignment. However, this does not affect the displaceability of the support element transversely to the longitudinal axis of the fastening elements.

Im übrigen kann man den Spaltraum zwischen den Tragelementen und der Wand mit Dämmstoffen und/oder feuerhemmenden Stoffen so ausfüllen, daß eine gute Dämmung bzw. ein guter Feuerschutz gewährleistet, die Hinterlüftung aber nicht ausgeschaltet ist.In addition, the gap between the support elements and the wall can be filled with insulation and / or fire-retardant materials in such a way that good insulation or good fire protection is guaranteed, but the rear ventilation is not switched off.

Die Mutter weist bei einer bevorzugten Ausführungsform der Erfindung einen Bund und einen sich daran anschließenden, die Aufnahme durchsetzenden, hülsenförmigen Ansatz auf. Am Bund legt sich der U-Mittelsteg an, während der hülsenförmige Ansatz die gleitende Abstützung des Tragelements an dieser Stelle übernimmt. Aus diesem Grunde ist es zweckmäßig, hier für geeignete Materialpaarungen zu sorgen. Im Hinblick auf das gute Gleiten einerseits und auch eine gute Korrosionsbeständigkeit andererseits empfiehlt sich die Verwendung einer Mutter aus Kunststoff oder rostfreien bzw. rostgeschützten Mutter. Das andere Anschlagglied besteht in diesem Falle vorteilhafterweise aus einem insbesondere ringförmigen Stützglied, das an einem Außenbund des Befestigungselements oder einer Spannmutter anliegt bzw. beim Aufschrauben der Mutter anlegbar ist.In a preferred embodiment of the invention, the nut has a collar and an adjoining sleeve-shaped extension which penetrates the receptacle. The U-center bar is placed on the collar, while the sleeve-shaped attachment takes over the sliding support of the support element at this point. For this reason, it is advisable to provide suitable material combinations here. In view of the good gliding on the one hand and good corrosion resistance on the other hand, the use of a nut made of plastic or a rustproof or rustproof nut is recommended. In this case, the other stop member advantageously consists of an in particular ring-shaped support member which rests on an outer collar of the fastening element or a tension nut or can be put on when the nut is screwed on.

Eine andere Variante der Erfindung sieht vor, daß die Mutter einen Bund und das Stützglied einen in die Aufnahme hineinragenden, hülsenförmigen Ansatz aufweisen. In diesem Falle erfolgt also die Abstützung des Gewichts nicht über die Mutter, sondern über den Stützring. Hier empfiehlt es sich, beispielsweise eine Kunststoffmutter zu nehmen und den Stützring aus Aluminium oder rostgeschütztem Stahl herzustellen.Another variant of the invention provides that the nut has a collar and the support member has a sleeve-shaped projection protruding into the receptacle. In this case, the weight is not supported by the nut but by the support ring. Here it is advisable to take a plastic nut, for example, and to make the support ring from aluminum or rustproof steel.

Im übrigen sieht eine bevorzugte Ausbildung der Erfindung vor, daß das Tragelement, die Halteglieder und die Befestigungselemente allesamt aus nichtrostendem Material wie Aluminium, Kunststoff od. dgl. hergestellt und/oder mit einem gegen Korrosion schützenden Überzug versehen sind, damit sie eine lange Lebensdauer auch bei Feuchtigkeit gewährleisten und vom möglicherweise aggressiven Putz oder zumindest aggressiven Bestandteil des Putzes nicht angegriffen oder gar zerstört werden.In addition, a preferred embodiment of the invention provides that the support element, the holding members and the fastening elements are all made of rustproof material such as aluminum, plastic or the like and / or are provided with a protective coating against corrosion, so that they also have a long service life guarantee in damp conditions and are not attacked or even destroyed by the possibly aggressive plaster or at least aggressive part of the plaster.

Das stabförmige Tragelement kann im Grunde genommen in jeder beliebigen Lage eingebaut werden, jedoch sind seine bevorzugten Einbaulagen eine horizontale oder, wie in der Zeichnung dargestellt, eine vertikale Anordnung. Es besitzt mehrere, in Längsrichtung versetzt angeordnete Befestigungselemente 2, deren Länge sich nach den Gegebenheiten und der gewünschten Anbringungsart richtet. So ist es ohne weiteres möglich, die Befestigungselemente so lang zu wählen und in einer nicht dargestellten Wand od. dgl. zu verankern, daß das Tragelement von dieser Wand einen Abstand von einigen Zentimetern hat. Damit kann man zwischen dieser Wand und der « Rückseite des Tragelements beispielsweise Dämmplatten u. dgl. anbringen, während sich an der « Vorderseite ein sogenannter Putzträger 3 befindet. Er besteht vorzugsweise aus einer rückwärtigen Folie, beispielsweise Ölpapier, und kreuzweise angeordneten Längsstäben 4 und Querstäben 5, wie dies beispielsweise Fig. 1 zeigt. Halteglieder 6 des Tragelements 1 können so angeordnet und ausgebildet sein, daß man darauf beispielsweise die Querstäbe des Putzträgers 3 auflegen kann.The rod-shaped support element can basically be installed in any position, but its preferred installation positions are horizontal or, as shown in the drawing, a vertical arrangement. It has a plurality of fastening elements 2 arranged offset in the longitudinal direction, the length of which depends on the circumstances and the desired type of attachment. Thus, it is easily possible to choose the fastening elements so long and to anchor them in a wall (not shown) or the like, that the support element is at a distance of a few centimeters from this wall. So you can between this wall and the «back of the support element for example insulation boards u. Attach the like, while there is a so-called plaster base 3 on the front. It preferably consists of a rear film, for example oil paper, and crosswise arranged longitudinal bars 4 and cross bars 5, as shown for example in FIG. 1. Holding members 6 of the support element 1 can be arranged and designed such that the cross bars of the plaster base 3 can be placed thereon, for example.

Das Tragelement 1 ist vorzugsweise aus einem ebenen Blech hergestellt und durch mehrmaliges Abkanten zu einem Profilstab geformt. In bevorzugter Weise sind die Halteglieder einstückig mit dem Tragelement hergestellt, beispielsweise durch Ausstanzen und Umbiegen. Wenn man ihnen, wie beim Ausführungsbeispiel, eine pfeilartige Gestalt verleiht, so kann man damit die Folie des Putzträgers leicht durchstoßen und andererseits eine Anschlagfläche 7 für den Putzträger, insbesondere dessen Querstab 5, schaffen. Gemäß einer besonderen Ausgestaltung der Erfindung läßt man jedoch den Querstab nicht unmittelbar an dieser Anschlagfläche anliegen, vielmehr schaltet man eine abnehmbare, in der Art einer Tellerfeder ausgebildete Druckplatte 8 dazwischen, so daß man die Halteglieder6 vergleichsweise klein ausbilden und zusätzlich zu dem Querstab evtl. auch noch einen dort vorbeigeführten Längsstab festhalten bzw. an das Tragelement andrücken kann. Die Montage erfolgt durch einfaches Aufschieben senkrecht zur Längsrichtung des Halteglieds, und die Druckplatte besitzt zu diesem Zweck einen randoffenen Befestigungsschlitz 9.The support element 1 is preferably made of a flat sheet metal and formed into a profile bar by repeated folding. The holding members are preferably produced in one piece with the supporting element, for example by punching out and bending over. If, as in the exemplary embodiment, they are given an arrow-like shape, the film of the plaster base can be pierced easily and, on the other hand, a stop surface 7 for the plaster base, in particular its crossbar 5. According to a special embodiment of the invention, however, the crossbar is not allowed to rest directly on this stop surface, but rather a removable pressure plate 8 designed in the manner of a plate spring is interposed, so that the Form holding members 6 comparatively small and, in addition to the cross bar, possibly also hold a longitudinal bar that is guided past it or can press it onto the supporting element. The assembly is carried out by simply sliding it perpendicular to the longitudinal direction of the holding member, and for this purpose the pressure plate has an attachment slot 9 which is open at the edge.

Das Tragelement 1 besitzt, wie Fig. 1 der Zeichnung deutlich zeigt, einen etwa U-förmigen Querschnitt mit nach außen umgebogenen Schenkelenden. Letztere liegen in einer gemeinsamen Ebene, und sie bilden zwei im Abstand angeordnete Profilschenke110 und 11. Ihre in gleicher Richtung wie die freien Enden der Halteglieder weisenden Flächen stellen Stützflächen 12 bzw. 13 für den Putzträger 3 dar. Der mittige Profilteil 14 besitzt mehrere in Längsrichtung versetzt angeordnete, schlitzförmige Aufnahmen 15 für je ein Befestigungselement 2. Bei letzteren kann es sich im übrigen um Gewindebolzen, Ankerschrauben mit Gewinde, Dübel mit Gewinde u. dgl. handeln. Da die Befestigungselemente 2 fest mit einer Wand od. dgl. verbunden sind und daher nach der Montage keine Bewegungen mehr ausführen können, andererseits aber die Längsdehnung des Tragelements anders, insbesondere größer ist als die Längsdehnung der Wand od. dgl., erfolgt die Verbindung zwischen dem Tragelement und den einzelnen Befestigungselementen derart, daß eine Verschiebung in Richtung des Doppelpfeils 16 möglich ist. In Längsrichtung des Befestigungselement ist, wenn man von den Toleranzen absieht, die Verbindung als starr zu bezeichnen.The support element 1 has, as FIG. 1 of the drawing clearly shows, an approximately U-shaped cross section with leg ends bent outwards. The latter lie in a common plane and they form two spaced-apart profile legs 110 and 11. Their surfaces, which point in the same direction as the free ends of the holding members, represent support surfaces 12 and 13 for the plaster base 3. The central profile part 14 has several in the longitudinal direction staggered, slot-shaped receptacles 15 for one fastening element 2. In the latter case, it can also be threaded bolts, anchor bolts with thread, dowels with thread and the like. act. Since the fastening elements 2 are firmly connected to a wall or the like and can therefore no longer perform any movements after assembly, but on the other hand the longitudinal expansion of the support element is different, in particular greater than the longitudinal expansion of the wall or the like the support element and the individual fasteners such that a displacement in the direction of the double arrow 16 is possible. In the longitudinal direction of the fastener, apart from the tolerances, the connection can be described as rigid.

Die Aufnahme 15 kann als einfacher Längsschlitz ausgebildet sein oder aber als Längsschlitz mit einer Erweiterung 17 an seinem einen Ende. Sie ermöglicht das Einsetzen eines Gleitstücks 18 bzw. 19. Ersteres hat einen H-förmigen Querschnitt mit unterschiedlichen langen H-Schenkeln. In Längsrichtung ist die Länge des kürzeren H-Schenkels 20 etwa so groß wie die größte Breite der Aufnahme 15 im Bereich ihrer Erweiterung 17. Durch die zentrische Bohrung 21 ragt das freie Ende des Befestigungselements 2 hindurch, wobei insoweit auf Fig. 2 verwiesen wird, die allerdings kein derartiges Gleitstück zeigt. Beidseits des Gleitstücks befindet sich eine Mutter. Mit Hilfe dieser beiden Muttern kann man das Gleitstück nicht nur verschiebefest am Befestigungselement montieren, sondern auch seine genaue Lage am Befestigungselement und damit den Abstand des Tragelements von der Mauer od. dgl. bestimmen. Das Gleitstück kann, wie die Fig. 5 und 6 zeigen, auch einen kreiszylindrischen Außendurchmesser haben, wobei man die beiden Flanschen gleich groß wählen kann. In diesem Falle ist die Erweiterung 17 jedoch nicht rechteckig, sondern kreisrund, so daß insgesamt die Form eines Schlüssellochs entsteht.The receptacle 15 can be designed as a simple longitudinal slot or as a longitudinal slot with an extension 17 at one end. It enables the insertion of a slider 18 or 19. The former has an H-shaped cross section with different long H-legs. In the longitudinal direction, the length of the shorter H-leg 20 is approximately as large as the greatest width of the receptacle 15 in the area of its extension 17. The free end of the fastening element 2 projects through the central bore 21, reference being made to FIG. which, however, shows no such slider. There is a nut on both sides of the slider. With the help of these two nuts, you can not only mount the slider on the fastening element so that it cannot move, but also determine its exact position on the fastening element and thus the distance of the support element from the wall or the like. 5 and 6, the slider can also have a circular cylindrical outer diameter, and the two flanges can be chosen to be the same size. In this case, the extension 17 is not rectangular, but circular, so that the overall shape of a keyhole is created.

Eine andere Art der Verbindung zwischen Tragelement und Befestigungselement zeigt Fig.2. Auf das Gewinde bzw. den Gewindeteil des Befestigungselements 2 ist eine Mutter 22 mit Außenbund 23 aufgeschraubt. Außerdem besitzt diese Mutter noch einen, die Aufnahme 15 durchsetzenden, hülsenförmigen Ansatz 24. Sein Außendurchmesser entspricht etwa der Schlitzbreite der Aufnahme 15, die in diesem Falle keine Erweiterung 17 hat. Diese Mutter bildet das eine Anschlagglied für das Tragelement 1, während das andere Anschlagglied 25 aus einem insbesondere ringförmigen Stützglied besteht, das mit einer Unterlegscheibe vergleichbar ist. An letzteres schließt sich nach außen hin noch eine Spannmutter 26 an.Another type of connection between the support element and the fastening element is shown in FIG. 2. A nut 22 with an outer collar 23 is screwed onto the thread or the threaded part of the fastening element 2. In addition, this nut also has a sleeve-shaped extension 24 which penetrates the receptacle 15. Its outer diameter corresponds approximately to the slot width of the receptacle 15, which in this case has no extension 17. This nut forms the one stop member for the support element 1, while the other stop member 25 consists of a particularly annular support member which is comparable to a washer. The latter is followed by a clamping nut 26 on the outside.

Wenn man Fig. 2 der Zeichnung betrachtet, so ist leicht einzusehen, daß man den hülsenförmigen Ansatz 24 auch am anderen Anschlagglied 25 bzw. Stützglied anbringen kann und statt dessen die Mutter 22 nur mit einem Außenbund 23 ausstattet. Zusammengehalten wird diese Verbindung ebenfalls mit einer Spannmutter 26.If one looks at Fig. 2 of the drawing, it is easy to see that the sleeve-shaped extension 24 can also be attached to the other stop member 25 or support member and instead the nut 22 is only equipped with an outer collar 23. This connection is also held together with a clamping nut 26.

Alle erwähnten Teile dieses Tragelements sind entweder aus Kunststoff, Aluminium oder einem anderen, mit einem Schutzüberzug versehenen Metall, so daß sie weder durch Nässe und Feuchtigkeit, noch durch aggressive Bestandteile des Putzes angegriffen und beschädigt werden können.All mentioned parts of this support element are either made of plastic, aluminum or another metal provided with a protective coating, so that they can be attacked and damaged neither by moisture and moisture, nor by aggressive components of the plaster.
