In order to make it possible also to use normal facing stones, to be able to anchor the support element securely in the foundation masonry (14, 15), and to ensure reliable protection against wetness as well as good insulation, the wall mounting elements are constituted by grouting anchors (4) surrounded up to the support (2) by a sleeve (7) and exhibiting respectively a central anchoring bolt (5) with a barbed disk (6) arranged at the insert end (22), and the support (2) is constituted by an L-shaped rail (3), the grouting anchors (4) projecting from the vertical leg (8) of this rail on the side facing away from the horizontal leg (9).

Description

Die Erfindung betrifft ein konsolartiges Tragelement für Vorhangfassaden an Gebäudewänden, das nachträglich an der Gebäudewand zu befestigen ist, wobei das Tragelement aus einem horizontalen Träger mit mindestens zwei zugeordneten, bolzenartigen Wandbefestigungselementen besteht.The invention relates to a bracket-like support element for curtain walls on building walls, which is to be subsequently attached to the building wall, the support element consisting of a horizontal support with at least two associated, bolt-like wall fastening elements.

Es sind Vorhangfassaden bekannt, bei denen Konsolbalken nach Art eines Wandregalbrettes an der Außenseite von Gebäudewänden mit Hilfe von zwei Dübeln befestigt werden. Auf den dortigen Konsolbalken werden dann Flächenelemente für eine Verblendfassade aufgesetzt, wobei je nach Breite des Konsolbalkens zwischen dem Grundmauerwerk und der Verblendschale zusätzlich noch eine Dämmschicht eingelegt werden kann. Bei sehr hohen Gebäuden, bei denen die Belastung der tragenden Dübel zu groß würde, können mehrere Konsolbalken übereinander angebracht werden, die dann einzelne Fassadenteile tragen. Die bekannte Vorhangfassade hat den Vorteil, daß neben plattenförmigen Flächenelementen auch normale Verblendsteine auf den Konsolbalken aufgemauert werden können. Problematisch ist aber, daß bei älteren Gebäuden die Außenfläche des Grundmauerwerks häufig verwittert ist und daher darin eingebrachte Dübel nur begrenzt belastungsfähig sind. Nachteilig ist weiterhin, daß durch die Konsolbalken eine direkte Verbindung von der Vorhangfassade zum Grundmauerwerk geschaffen wird. Infolgedessen wird auf der Innenseite der Vorhangschale herablaufendes Wasser regelrecht zum Grundmauerwerk hingeleitet, wobei gleichzeitig eine evtl. eingelegte Schicht von Dämmaterial durchnäßt wird. Außerdem stellen die Konsolbalken über die gesamte Gebäudebreite reichende Wärmeleitbrücken dar, so daß es in den Gebäudewänden zu Temperaturspannungen, Kondenswasserbildung und dgl. kommen kann.Curtain walls are known in which bracket beams are attached to the outside of building walls in the manner of a wall shelf board with the aid of two dowels. Surface elements for a facing facade are then placed on the bracket beams there, and depending on the width of the bracket beams, an insulation layer can also be inserted between the basic masonry and the facing shell. In very tall buildings, where the load on the load-bearing dowels would be too great, several bracket beams can be attached one above the other, which then support individual facade parts. The known curtain wall has the advantage that, in addition to plate-shaped surface elements, normal facing bricks can also be built on the bracket beams. It is problematic, however, that in older buildings the outer surface of the basic masonry is often weathered and therefore the dowels inserted into it are only able to withstand loads to a limited extent. Another disadvantage is that the bracket beams create a direct connection from the curtain wall to the base masonry. As a result, water running down on the inside of the curtain shell is literally led to the basic masonry, at the same time a possibly inserted layer of insulating material is soaked. In addition, the bracket beams represent thermal conduction bridges spanning the entire width of the building, so that temperature tensions, condensation and the like can occur in the building walls.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Tragelement für Vorhangfassaden an Gebäudewänden zu schaffen, bei welchem auch die Verwendung von normalen Verblendsteinen möglich ist, welches sicher im Grundmauerwerk verankert werden kann und welches einen zuverlässigen Nässeschutz sowie eine gute Isolierung gewährleistet.The invention has for its object to provide a generic support for curtain walls on building walls, in which the use of normal facing bricks is possible, which can be securely anchored in the basic masonry and which ensures reliable protection against moisture and good insulation.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Wandbefestigungselemente Injektionsanker sind, welche bis zum Träger hin von einem Injektionsstrumpf umschlossen sind und jeweils einen zentralen Verankerungsbolzen mit am Einsetzende angeordneter Widerhakenscheibe aufweisen, und daß der Träger eine L-Schiene ist, von deren Vertikalschenkel die Injektionsanker auf der dem Horizontalschenkel abgewandten Seite abragen.This object is achieved in that the wall fastening elements are injection anchors, which are enclosed up to the support by an injection stocking and each have a central anchoring bolt with a barbed disc arranged at the insertion end, and in that the support is an L-rail, from the vertical leg of which the injection anchors protrude on the side facing away from the horizontal leg.

Durch die Verwendung von Injektionsankern läßt sich auch in älterem, verwittertem Mauerwerk eine sehr solide Befestigung des Tragelementes erreichen, wobei durch die am Einsetzende angeordnete Widerhakenscheibe eine besonders hohe Auszugsfestigkeit der Injektionsanker gegeben ist. Injektionsanker können so weit abkragend eingesetzt werden, daß zwischen der als Träger benutzten L-Schiene und dem Grundmauerwerk eine Schicht von Wärmedämmaterial eingelegt werden kann.Through the use of injection anchors, very solid fastening of the support element can also be achieved in older, weathered masonry, with the barbed washer arranged at the end of the insertion providing a particularly high pull-out strength of the injection anchors. Injection anchors can be used so cantilever that a layer of thermal insulation material can be inserted between the L-rail used as a support and the basic masonry.

Bei dem erfindungsgemäßen Tragelement sind allenfalls die Injektionsanker als Wärmeleitbrücken zu betrachten, die aber aufgrund ihres geringen Querschnitts nur unwesentlich Wärme leiten können.In the case of the supporting element according to the invention, the injection anchors are at most to be regarded as thermal bridges, which, however, can conduct heat only insignificantly due to their small cross section.

Als besonderer Vorteil des erfindungsgemäßen Tragelementes ist es anzusehen, daß es nicht nur an Gebäuden mit einschaligem Grundmauerwerk eingesetzt werden kann, sondern daß auch eine Sanierung eines mehrschaligen, eine Verblendschale bereits aufweisenden Mauerwerks möglich ist, ohne daß die alte Verblendschale abgerissen werden muß. Infolge der durch die L-Schiene verbundenen Injektionsanker ergibt sich vielmehr sogar eine Stabilisierung der mehrschaligen Grundkonstruktion. Insbesondere wenn ältere Luftschichtanker zwischen den verschiedenen Scheiben korrodiert oder abgeschert sind, stellen die Injektionsanker die Verbindung zwischen den verschiedenen Schalen wieder her und erhöhen insbesondere die Biege-und Beulsteifigkeit der alten Verblendfassade. Die verschiedenen Schalen werden zu einer einheitlichen, quasi kastenförmigen Gesamtkonstruktion vereinigt. In Weiterbildung der Erfindung kann vorgesehen werden, daß der Horizontalschenkel des Trägers gleich breit wie die Flächenelemente der Vorhangfassade ist, und daß auf den Injektionsankern kurz hinter dem Vertikalschenkel je eine Tropfscheibe angeordnet ist. Bei dieser Ausführungsform kragen die Injektionsanker so weit ab, daß zwischen dem Vertikalschenkel der L-Schiene und dem Grundmauerwerk bzw. der Wärmedämmschicht ein größerer Luftspalt verbleibt, der auf der Innenseite der Fassadenschale ein unbehindertes Ablaufen von Wasser gestattet. Die auf den Injektionsankern angeordnete Tropfscheibe sorgt dafür, daß auch an den Injektionsankern selbst ein Übertreten von Wasser zum Grundmauerwerk sicher unterbunden ist.A particular advantage of the support element according to the invention is that it can not only be used on buildings with single-layer basic masonry, but also that renovation of a multi-layer masonry that already has a facing shell is possible without the old facing shell having to be torn off. As a result of the injection anchors connected by the L-rail, there is even a stabilization of the multi-shell basic construction. In particular when older air layer anchors between the different panes are corroded or sheared off, the injection anchors restore the connection between the different shells and in particular increase the bending and buckling stiffness of the old facing facade. The various shells are combined into a uniform, quasi-box-shaped overall construction. In a further development of the invention it can be provided that the horizontal leg of the carrier is the same width as the surface elements of the curtain wall, and that a drip disk is arranged on the injection anchors just behind the vertical leg. In this embodiment, the injection anchors protrude so far that a larger air gap remains between the vertical leg of the L-rail and the basic masonry or the thermal insulation layer, which allows an unimpeded drainage of water on the inside of the facade shell. The drip plate arranged on the injection anchors ensures that water does not enter the base masonry.

Gemäß der Erfindung können die Verankerungsbolzen an den Vertikalschenkel der L-Schiene angeschweißt sein. Bei diesem Aufbau werden die konsolenartigen Tragelemente als Ganzes an einer Gebäudewand befestigt.According to the invention, the anchoring bolts can be welded to the vertical leg of the L-rail. With this construction, the bracket-like support elements are attached as a whole to a building wall.

Gemäß einer abgewandelten Ausführungsform der Erfindung können die Verankerungsbolzen an den Vertikalschenkel der L-Schiene angeschraubt sein. Bei dieser Ausgestaltung können die einzelnen Tragelemente in zerlegter Form zur Baustelle transportiert werden. Je nach Zweckmäßigkeit können dann zunächst die Injektionsanker für sich allein oder aber die kompletten, nunmehr montierten Tragelemente eingesetzt werden. Durch die Verschraubung besteht die Möglichkeit, nach Art eines Baukastensystems L-Schienen unterschiedlicher Länge und Injektionsanker verschiedener Größe ausgerichtet auf die jeweiligen Erfordernisse miteinander zu verbinden. So ist es beispielsweise möglich, einen der beiden Injektionsanker eines Tragelementes größer zu wählen, wenn an der jeweiligen Stelle das Grundmauerwerk sehr brüchig ist oder wenn dieser Injektionsanker zusätzliche Belastungen aufzunehmen hat.According to a modified embodiment of the invention, the anchoring bolts can be screwed onto the vertical leg of the L-rail. In this embodiment, the individual support elements can be transported to the construction site in disassembled form. Depending on the expediency, the injection anchors can then be used on their own or the complete, now assembled support elements. The screw connection enables L-rails of different lengths and injection anchors of different sizes to be connected to one another in line with the respective requirements in the manner of a modular system. For example, it is possible to choose one of the two injection anchors of a support element larger if the base masonry is very fragile at the respective point or if this injection anchor has to absorb additional loads.

Der Erfindung zufolge können die Vertikalschenkel der L-Schienen horizontal gerichtete Langlöcher für die Anschraubenden der Verankerungsbolzen aufweisen. Durch die Langlöcher können Abstandsungenauigkeiten beim Einsetzen der Injektionsanker ausgeglichen werden. Der wesentliche Zweck der Langlöcher besteht aber darin, daß bei nur begrenzt fester Anschraubung der Verankerungsbolzen eine horizontale Relativbewegung zwischen der L-Schiene und den Injektionsankern zum Ausgleich von Wärmedehnungen eintritt. Dabei ist zu bedenken, daß die Temperatur der Außenfassade zwischen -20°C und +80°C - schwanken kann, während die Temperatur des ein-oder mehrschaligen Grundmauerwerks nur weitaus geringeren Änderungen unterworfen ist. Insbesondere bei einem mehrschaligen Grundmauerwerk ergibt sich damit der Vorteil, daß durch die vorgesetzte Fassadenschale die Schwankungen der Außentemperatur ausgeglichen werden, während die Schalen des Grundmauerwerks durch die Injektionsanker -ohne die Gefahr von Wärmespannungen -starr miteinander verbunden sind und damit das Grundmauerwerk insgesamt stabilisiert wird.According to the invention, the vertical legs of the L-rails can have horizontally oriented elongated holes for the screw-on ends of the anchoring bolts. The elongated holes can compensate for inaccuracies in the spacing when inserting the injection anchors. The main purpose of the elongated holes is, however, that when the anchoring bolts are screwed on only to a limited extent, a horizontal relative movement between the L-rail and the injection anchors occurs to compensate for thermal expansion. It should be borne in mind that the temperature of the outer facade can fluctuate between -20 ° C and + 80 ° C -, while the temperature of the single or multi-layered basic masonry is subject to far less changes. In particular in the case of multi-layered basic masonry, there is the advantage that the fluctuations in the outside temperature are compensated for by the facing facade shell, while the shells of the basic masonry are rigidly connected to one another by the injection anchors - without the risk of thermal stresses - and thus the overall basic masonry is stabilized.

In weiterer Ausgestaltung der Erfindung kann dem Tragelement ein Fugenschlauch, vorzugsweise von gleicher Länge wie die einer L-Schiene, angeordnet sein, welcher mit einer Einspritzöffnung zum Einpressen von Mörtel versehen ist. Der Fugenschlauch dient dabei zum wasserdichten Abschließen des Spaltes zwischen mehreren übereinandergesetzten Teilen einer Vorhangfassade mit mehreren Tragelementen. Der Abdichtung dieses Spaltes kommt eine besondere Bedeutung zu, weil an dieser Stelle das Wasser von der nächst oberen L-Schiene abfließt.In a further embodiment of the invention, a joint hose, preferably of the same length as that of an L-rail, can be arranged on the support element, which is provided with an injection opening for pressing in mortar. The joint hose is used to seal off the gap between several superimposed parts of a curtain wall with several supporting elements. The sealing of this gap is of particular importance because the water flows off the next upper L-rail at this point.

Gemäß der Erfindung kann die Länge der Verankerungsbolzen mehr als dreißig Zentimeter betragen. Bei dieser Mindestlänge kann das Tragelement sicher an einem zweischaligen Grundmauerwerk befestigt werden.According to the invention, the length of the anchoring bolts can be more than thirty centimeters. With this minimum length, the support element can be securely fastened to a double-shell basic masonry.

In weiterer Ausgestaltung der Erfindung können an den Tragelementen Anschlußelemente für Gerüste oder Seile angebracht sein. Da die Injektionsanker eine sehr hohe Auszugsfestigkeit besitzen, können auf die Tragelemente problemlos auch zusätzliche Belastungen aufgebracht werden. Die Anschlußelemente können mit den L-Schienen oder den Verankerungsbolzen der Tragelemente verschweißt oder verschraubt werden. Die Verankerungsbolzen können auch aus Vierkantrohren bestehen.In a further embodiment of the invention, connection elements for scaffolding or ropes can be attached to the support elements. Since the injection anchors have a very high pull-out strength, additional loads can easily be applied to the support elements. The connection elements can be welded or screwed to the L-rails or the anchoring bolts of the support elements. The anchoring bolts can also consist of square tubes.

The anchoring bolts 5 are welded to a vertical leg 8 of the L-rail 3 in such a way that they protrude vertically from the L-rail 3 on the side facing away from the horizontal leg 9.

Bei dem in Fig. 2 gezeigten Tragelement 10 ist in Besonderheit aber die Verbindung zwischen dem Vertikalschenkel 8 der L-Schiene 3 und dem Verankerungsbolzen 5 durch Schrauben 11 mit Unterlegscheibe 12 hergestellt.In the support element 10 shown in FIG. 2, the connection between the vertical leg 8 of the L-rail 3 and the anchoring bolt 5 is made by screws 11 with a washer 12.

Die Fig. 3 bis 5 veranschaulichen den Aufbau einer Vorhangfassade 13, bei welcher Tragelemente 10 entsprechend Fig. 2 verwendet sind. Die Vorhangfassade 13 ist dabei an einem zweischaligen Grundmauerwerk angebracht, welches aus einer vorderen Verblendschale 14 und einer Hintermauerschale 15 mit dazwischenliegender Luftschicht 16 besteht. Die Verankerungsbolzen 5 der Tragelemente 10 sind etwas mehr als dreißig Zentimeter lang, so daß sie in eine Bohrung 17 eingesetzt werden können, welche durch die Verblendschale 14 hindurch bis in die Hintermauerschale 15 hineinreicht.3 to 5 illustrate the structure of a curtain wall 13, in which support elements 10 are used according to FIG. 2. The curtain wall 13 is attached to a two-shell basic masonry, which consists of a front facing shell 14 and a rear wall shell 15 with an air layer 16 in between. The anchoring bolts 5 of the supporting elements 10 are a little more than thirty centimeters long so that they can be inserted into a bore 17 which extends through the facing shell 14 into the rear wall shell 15.

Bei der Montage der neuen Vorhangfassade 13 werden zunächst die Injektionsanker 4 in die Bohrlöcher 17 eingeführt. Durch Injektionsbohrungen 18 am Anschraubende 19 der Injektionsanker 4 wird dann der hohle Verankerungsbolzen 5 mit Injektionsmasse 20 gefüllt, die durch eine oder mehrere Austrittsbohrungen 21 in der Nähe des Einsetzendes 22 nach außen dringt. Auf diese Weise wird der Injektionsstrumpf 7 zunehmend mit Injektionsmasse 20 gefüllt und legt sich dicht an den Wänden der Bohrung 17 an. Für den Fall, daß die Wände der Bohrung 17 an einzelnen Stellen 23, 24 ausgebrochen sind, legt sich der Strumpf 7 in diese Vertiefungen hinein, verhindert aber gleichzeitig ein zu starkes Abfließen der Injektionsmasse 20 in Risse 25 oder dgl. Nach dem Aushärten der Injektionsmasse 20 ergibt sich eine sehr solide Verbindung zwischen dem Injektionsanker 4 und dem zweischaligen Mauerwerk 14, 15, wobei die nunmehr durch die Injektionsmasse 20 festgehaltene Widerhakenscheibe 6 für eine hohe Auszugsfestigkeit des Verankerungsbolzens 5 sorgt. Die Widerhakenscheibe 6 verhindert außerdem bei der Injektion ein Übertreten von Injektionsmasse 20 in die Spitze des Bohrloches 17, wodurch der Verankerungsbolzens 5 aus dem Bohrloch 17 herausgedrückt werden könnte.When installing the new curtain wall 13, the injection anchors 4 are first inserted into the boreholes 17. The hollow anchoring bolt 5 is then filled with injection compound 20 through injection bores 18 on the screw-on end 19 of the injection anchor 4, which penetrates through one or more outlet bores 21 in the vicinity of the insertion end 22. In this way, the injection stocking 7 is increasingly filled with injection compound 20 and lies tightly against the walls of the bore 17. In the event that the walls of the bore 17 have broken out at individual points 23, 24, the stocking 7 lies in these depressions, but at the same time prevents the injection compound 20 from flowing too strongly into cracks 25 or the like. After the injection compound has hardened 20 results in a very solid connection between the injection anchor 4 and the double-shell masonry 14, 15, the barbed disc 6 now held in place by the injection compound 20 ensuring a high pull-out strength of the anchoring bolt 5. The barbed disk 6 also prevents injection compound 20 from passing into the tip of the borehole 17 during the injection, as a result of which the anchoring bolt 5 could be pressed out of the borehole 17.

In der Luftschicht 16 zwischen der Verblendschale 14 und der Hintermauerschale 15 weitet sich der Injektionsstrumpf 7 wulstförmig auf, so daß nach dem Aushärten der Injektionsmasse 20 die beiden Schalen 14, 15 gegeneinander abgestützt sind. Für den Fall, daß schon vorher zwischen den beiden Schalen 14, 15 vorhandene Drahtanker 26 korrodiert oder abgeschert sind, wird deren Stützfunktion hinsichtlich einer Biege-oder Beulbelastung der Verblendschale 14 nunmehr durch den Injektionsanker 4 übernommen.In the air layer 16 between the facing shell 14 and the rear wall shell 15, the injection stocking 7 widens in a bead-like manner, so that after the injection compound 20 has hardened, the two shells 14, 15 are supported against one another. In the event that existing wire anchors 26 are corroded or sheared between the two shells 14, 15, their support function with regard to bending or buckling loading of the facing shell 14 is now taken over by the injection anchor 4.

Die Injektionsanker 4 ragen ein Stück weit aus der alten Verblendschale 14 heraus, so daß die L-Schiene 3 mit Abstand zur Verblendschale 14 an den Injektionsankern 4 angeschraubt werden kann. Der Injektionsstrumpf 7, der bis an den Vertikalschenkel 8 der L-Schiene 3 heranreicht und dessen vordere Öffnung dort von einem Gummiring 27 zusammengehalten ist, bildet zwischen der L-Schiene 3 und der Verblendschale 14 einen weiteren verbreiterten Wulst, welcher ebenfalls eine abstützende Funktion hat. In den freien Raum zwischen der alten Verblendschale 14 und der L-Schiene 3 ist eine Wärmedämmschicht 28 eingelegt.The injection anchors 4 protrude a little from the old facing shell 14, so that the L-rail 3 can be screwed onto the injection anchors 4 at a distance from the facing shell 14. The injection stocking 7, which reaches up to the vertical leg 8 of the L-rail 3 and the front opening of which is held together by a rubber ring 27, forms a further widened bead between the L-rail 3 and the facing shell 14, which also has a supporting function . A heat insulation layer 28 is inserted into the free space between the old facing shell 14 and the L-rail 3.

Die Horizontalschenkel 9 der L-Schienen 3 tragen jeweils übereinander und nebeneinander angeordnete Flächenelemente 29, welche zusammen die Fassadenschale 13 bilden. In der Luftschicht zwischen Vorhangfassade 13 und Verblendschale 14 anfallende Kondensatfeuchte und ggfs. durch die Vorhangfassade 13 durchgeschlagene Niederschlagsfeuchte wird an der Rückseite 33 der Flächenelemente 29 nach unten abgeleitet und fließt jeweils über die Enden des Horizontalschenkels 9 der L-Schienen 3 nach unten ab. An dem unteren Rand der Fassadenschale 13 kann das Wasser frei in den Untergrund 35 abfließen; vgl. Fig. 4.The horizontal legs 9 of the L-rails 3 each have surface elements 29 arranged one above the other and next to one another, which together form the facade shell 13. In the air layer between the curtain wall 13 and the facing shell 14, any condensate moisture and, if necessary, precipitation moisture penetrated through the curtain wall 13 is drained down at the rear 33 of the surface elements 29 and flows downward over the ends of the horizontal leg 9 of the L-rails 3. At the lower edge of the facade shell 13, the water can flow freely into the underground 35; see. Fig. 4.

Die Anschlußfuge zwischen der Oberseite eines Flächenelementes 29 und der darüberliegenden L-Schiene 3 wird durch einen Fugenschlauch 38 geschlossen, welcher mit einer Einspritzöffnung 39 zum Einpressen von Mörtel versehen ist. Um eine vollständige Füllung des Fugenschlauches 38 erreichen zu können, weist dieser außerdem eine Luftaustrittsöffnung 40 auf; vgl. Fig. 6.The connection joint between the top of a surface element 29 and the L-rail 3 lying above it is closed by a joint hose 38 which is provided with an injection opening 39 for injecting mortar. In order to be able to achieve a complete filling of the joint hose 38, this also has an air outlet opening 40; see. Fig. 6.

Der Verikalschenkel 8 der L-Schienen 3 ist mit horizontal gerichteten Langlöchern 41 für die Anschraubenden 19 der Verankerungsbolzen 5 versehen. Wenn die Schrauben 11 nur mäßig angezogen werden und die Unterlegscheiben 12 eine glatte, reibungsarme Oberfläche besitzen, ist aufgrund der Langlöcher 41 ein Temperaturausgleich zwischen dem Grundmauerwerk 14, 15 und der Fassadenschale 13 möglich. In dem gezeigten Ausführungsbeispiel sind die Schrauben 11 unmittelbar in die Injektionsbohrungen 18 eingeschraubt, so daß sich beim Aushärten der Injektionsmasse 20 eine Verklebung der Schrauben 11 ergibt. Sie können sich daher auch bei sehr starken Wärmedehnungen nicht selbsttätig lösen. Grundsätzlich ist es natürlich auch möglich, die Injektionsbohrungen und die Einschraubbohrungen voneinander getrennt auszuführen und andere Sicherungsmaßnahmen für die Schrauben 11 vorzusehen.The vertical leg 8 of the L-rails 3 is provided with horizontally directed elongated holes 41 for the screw-on ends 19 of the anchoring bolts 5. If the screws 11 are only moderately tightened and the washers 12 have a smooth, low-friction surface, temperature compensation between the basic masonry 14, 15 and the facade shell 13 is possible due to the elongated holes 41. In the exemplary embodiment shown, the screws 11 are screwed directly into the injection bores 18, so that the screws 11 are bonded when the injection compound 20 hardens. Therefore, they cannot come loose automatically even with very strong thermal expansions. In principle, it is of course also possible to carry out the injection bores and the screw-in bores separately from one another and to provide other securing measures for the screws 11.

In dem Ausführungsbeispiel nach Fig. 7 ist eine Vorhangfassade 42 gezeigt, welche an einem einschaligen Grundmauerwerk 43 befestigt ist. Zur Verankerung sind dabei Tragelemente 1 gemäß Fig. 1 verwendet, bei welchen die Injektionsanker 4 an den L-Schienen 3 angeschweißt sind. Die Vertikalschenkel 8 der L-Schienen 3 weisen daher eine Injektionsöffnung 44 für die Injektionsmasse 20 auf. Auf dem Horizontalschenkel 9 der L-Schienen 3 sind normale Verblendsteine 45 aufgemauert, welche die einzelnen Flächenelemente 46 der Fassadenschale 47 bilden. Die Verblendsteine 45 liegen unmittelbar am Vertikalschenkel 8 der L-Schienen 3 an. Die Injektionsanker 4 sind aber in dem Grundmauerwerk 43 so weit abkragend eingesetzt, daß auch bei Einlegen einer Wärmedämmschicht 28 noch ein Luftspalt 48 verbleibt, der ein einwandfreies Abfließen von Wasser an der Rückseite 49 der Fassadenschale 47 erlaubt. Um im Bereich der Injektionsanker 4 ein Übertreten des Wassers zur Wärmedämmschicht 28 und zum Grundmauerwerk 43 zu verhindern, tragen die Injektionsanker 4 kurz hinter den Vertikafschenkein 8 der L-Schienen 3 Tropfscheiben 50.In the exemplary embodiment according to FIG. 7, a curtain wall 42 is shown, which is fastened to a single-layer basic masonry 43. Carrying elements 1 according to FIG. 1 are used for anchoring, in which the injection anchors 4 are welded to the L-rails 3. The vertical legs 8 of the L-rails 3 therefore have an injection opening 44 for the injection compound 20. On the horizontal leg 9 of the L-rails 3, normal facing bricks 45 are bricked up, which form the individual surface elements 46 of the facade shell 47. The facing stones 45 lie directly on the vertical leg 8 of the L-rails 3. The injection anchors 4 are, however, inserted so cantilevered in the basic masonry 43 that an air gap 48 remains even when a thermal insulation layer 28 is inserted, which allows water to flow away from the rear 49 of the facade shell 47. In order to prevent the water from passing over to the thermal insulation layer 28 and to the basic masonry 43 in the area of the injection anchors 4, the injection anchors 4 carry drip disks 50 shortly behind the vertical legs 8 of the L-rails 3.

In Fig. 7 ist außerdem ein Anschlußelement 51 für eine Seilverankerungsöse 52 gezeigt, welches an der L-Schiene 3 angeschweißt ist. Das Anschlußelement 51 ist in dem gezeigten Beispiel eine Innengewindebuchse, an welcher im Bedarfsfall auch Gerüste oder dgl. befestigt werden können. Der im Bereich des Anschlußelementes 51 auf der L-Schiene 3 aufgesetzte Verblendstein ist mit einer entsprechenden Aussparung 53 versehen. Selbstverständlich können derartige Anschlußelemente 51 auch bei einer Ausführungsform nach den Fig. 3 bis 5 vorgesehen sein.FIG. 7 also shows a connection element 51 for a cable anchoring eyelet 52, which is welded to the L-rail 3. In the example shown, the connecting element 51 is an internally threaded bushing, to which scaffolding or the like can also be attached if necessary. The facing stone placed on the L-rail 3 in the area of the connecting element 51 is provided with a corresponding recess 53. Of course, such connection elements 51 can also be provided in an embodiment according to FIGS. 3 to 5.

Fig. 8 zeigt eine Verbindungslasche 54 zum seitlichen Anschluß zweier benachbarter Tragelemente 1. Die Lasche 54 ist mit in ihrer Längsrichtung verlaufenden Langlöchem 55 zum Ausgleich von Temperaturschwankungen versehen und wird an die Vertikalschenkel der L-Schienen 3 angeschraubt. Fig. 9 zeigt eine Winkelverbindungslasche 56 für Innen-und Außenecken, die ebenfalls mit Langlöchem 55 versehen ist.8 shows a connecting bracket 54 for the lateral connection of two adjacent support elements 1. The bracket 54 is provided with elongated holes 55 in its longitudinal direction to compensate for temperature fluctuations and is screwed onto the vertical legs of the L-rails 3. FIG. 9 shows an angle connection bracket 56 for inside and outside corners, which is also provided with elongated holes 55.
