Aus der WO 89/11010 ist eine mit durchsichtigen Bauelementen gebildete Dachkonstruktion bekannt, wobei die Bauelemente auch aus Glas bestehen können. Dabei wird ein typisches Beispiel einer bekannten Glasdachkonstruktion hinsichtlich der Lichttransmission bei Sonneneinstrahlung weitergebildet. Im Ausführungsbeispiel sind lichtdurchlässige, aus zwei transparenten im wesentlichen U-profilförmigen Teilelementen aus Acryl oder Polycarbonat bestehende Bauelemente angegeben, wobei die beiden Teilelemente und benachbarte Bauelemente durch eine- Schnapp- oder Rastverbindung, welche auf die Schenkel der im wesentlichen U-profilförmigen, ineinander gelegten Teilelemente aufgeklipst werden, verbunden sind. From WO 89/11010 is a roof structure formed with transparent components known, the components can also consist of glass. It becomes a typical one Example of a known glass roof construction with regard to light transmission Continued training in solar radiation. In the exemplary embodiment are translucent, from two transparent, essentially U-shaped partial elements made of acrylic or polycarbonate existing components specified, the two sub-elements and neighboring Components by a snap or snap connection, which on the legs of the essential U-profile-shaped, nested partial elements are clipped on, are connected.

Es ist aber bisher noch kein Glasbauelement bekannt, mit dem Decken- oder Dachabschnitte von Gebäuden sicher genug selbsttragend, d. h. ohne zusätzliche Rahmen- oder Stützelemente auskommend, aufgebaut werden könnten. Deswegen werden Dach- oder Deckenabschnitte aus oder mit Glas zur Zeit aus Sicherheitsgründen stets mit Einfassungen, das heißt zum Beispiel mit Rahmenelementen aus Metall oder dezgleichem nicht bruchgefährdeten Material aufgebaut Die Stabilitätsanforderungen an Glasdecken oder -dächer sind nämlich besonders hoch, da Decken und Dächer schon aufgrund ihres Eigengewichts und auch gegebenenfalls aufgrund von Dachlasten wie Schnee oder Eis besonders hohen Biegebelastungen ausgesetzt sind. Außerdem müssen Personen, die sich unter Decken oder Dächern aufhalten, im Fall des Bruches von dabei verwendeten Gläsern wirksam vor Splittern geschützt werden. Würde ein Teil eines Glasdaches brechen, so könnten genügend große herabfallende Splitter zu schweren oder gar tödlichen Verletzungen einer sich darunter befindlichen Person führen.So far, however, no glass component is known, with the ceiling or roof sections of buildings self-supporting safely enough, d. H. without additional frame or support elements getting along, could be built up. That is why roof or ceiling sections are made or with glass at the moment for security reasons always with borders, that is for example with frame elements made of metal or similar material that is not at risk of breakage The stability requirements for glass ceilings or roofs are special high, because ceilings and roofs are due to their own weight and also if necessary exposed to particularly high bending loads due to roof loads such as snow or ice are. In addition, people who are under ceilings or roofs must in the case of Breakage of glasses used in this way can be effectively protected against splinters. Would one Breaking part of a glass roof, large enough falling fragments could become serious or even fatal injuries to a person below.

Aufgabe der Erfindung ist es, ein Glasbauelement zu schaffen, mit dem selbsttragende Dach- oder Deckenabschnitte gebildet werden können, die den Anforderungen bezüglich Belastbarkeit, insbesondere Biegebelastbarkeit, Schutz vor Fremdeinflüssen und Splitterschutz genügen.The object of the invention is to provide a glass component with which self-supporting roof or ceiling sections can be formed that meet the requirements Resilience, especially bending resistance, protection against external influences and splinter protection suffice.

Diese Aufgabe wird erfindungsgemäß durch ein Glasbauelement mit den Merkmalen des beigefügten Anspruchs 1 gelöst.This object is achieved by a glass component with the features of attached claim 1 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß ist somit vorgesehen, daß das Glasbauelement aus wenigstens zwei miteinander großflächig mittels eines Klebemittels fest verklebten Teilelementen besteht, von denen wenigstens ein erstes Teilelement ein Glasprofilelement ist.According to the invention it is thus provided that the glass component consists of at least two firmly together with an adhesive glued sub-elements, of which at least a first sub-element Glass profile element is.

Wie eingangs bereits erwähnt, sind insbesondere L- oder U-förmige Glasprofilelemente bereits in sich selbst so stabil, daß sie zum Bilden selbsttragender Wandabschnitte verwendbar sind. Zur Verstärkung des als ersten Teilelements verwendeten Glasprofilelements ist erfindungsgemäß wenigstens noch ein zweites Teilelement vorgesehen, das breit- oder großflächig mit dem ersten Teilelement verklebt ist. Hierzu werden zwei Flächen der beiden Teilelemente mittels eines Klebemittels als Verbundmittel vorzugsweise ganzflächig fest miteinander verbunden. Dies ergibt eine enorme Verstärkung bei nur geringer Gewichtszunahme. Wird eines der beiden Teilelemente durch Fremdeinflüsse oder Überbelastung zerstört, so bleiben die Splitter aufgrund des Klebemittels dennoch am anderen Teilelement hängen. Durch das erfindungsgemäße Glasbauelement werden daher Personen wirksam vor Splittern geschützt. Dies ist insbesondere bei über Kopf zu verwendenden Glasbauelementen wichtig.As already mentioned at the beginning, in particular L or U-shaped glass profile elements are already so stable in itself that they can be used to form self-supporting wall sections. To reinforce the glass profile element used as the first partial element, the invention at least a second sub-element is provided, the broad or large area with the first sub-element is glued. For this purpose, two surfaces of the two sub-elements are used of an adhesive as a composite, preferably firmly connected to one another over the entire surface. This results in an enormous gain with only a small weight gain. If one of the The two fragments are destroyed by external influences or overloading hang on the other part due to the adhesive. By the Glass component according to the invention are therefore effectively protected against splinters. This is particularly important for glass components to be used overhead.

Weiter ist erfindungsgemäß das erste Teilelement im Querschnitt U-förmig mit zwei Schenkeln und einem Steg dazwischen oder quasi als halbiertes U-Profil L-förmig mit einem Steg und nur einem Schenkel. Damit das Glasbauelement den besonders hohen Belastungen in einer selbsttragenden Decken- oder Dachkonstruktion standhält, ist erfindungsgemäß vorgespanntes oder teilvorgespanntes Glas als Material für das erste Teilelement vorgesehen. Einen besseren Splitterschutz als Drahtglas bietet nämlich ein gehärtetes Glas, das als Einscheibensicherheitsglas bezeichnet wird. Einscheibensicherheitsglas ist vorzugsweise ein Floatglas, das nochmals auf hohe Temperaturen, beispielsweise 600° erhitzt und durch Kaltluft abgeschreckt worden ist und dadurch eine erhöhte Oberflächenspannung, eine gewisse Spannung und Elastizität erhält und Brösel bildet, wenn es mit spitzem Gegenstand geschlagen wird. Neben vorgespanntem Glas ist auch der Einsatz eines teilvorgespannten Glases denkbar, dessen Splitterstücke bei einem Bruch etwas größer sind als die Brösel des vorgespannten Glases und damit besser an dem Verbundmittel haften bleiben, aber dennoch kleiner als die Bruchstücke von Glas mit unbehandelten Oberflächen sind.According to the invention, the first partial element is U-shaped in cross section with two Thighs and a web in between or quasi as a halved U-shaped L-shaped with one Bridge and only one leg. So that the glass component withstands the particularly high loads in a self-supporting ceiling or roof construction is according to the invention toughened or partially toughened glass is provided as the material for the first partial element. A better protection against splinters than wired glass is provided by hardened glass, which as Single-pane safety glass is called. Single-pane safety glass is preferably a Float glass, which heats up again to high temperatures, for example 600 °, and by cold air has been quenched and thereby an increased surface tension, a certain Maintains tension and elasticity and forms crumbs when struck with a pointed object becomes. In addition to tempered glass, the use of partially tempered glass is also conceivable, the fragments of which, when broken, are slightly larger than the crumbs of the prestressed one Glass and thus stick better to the composite, but still smaller than that Fragments of glass with untreated surfaces are.

Als Klebemittel sind erfindungsgemäß Materialien vorgesehen, die auch bei Verbundglasscheiben benutzt werden, nämlich Klebefolien, Gießharze und Expoxydharze. According to the invention, materials are provided as adhesives which also include Laminated glass panes are used, namely adhesive films, casting resins and epoxy resins.

Es sind zwar also bereits Verbundglasscheiben bekannt, d. h. weitgehend plan ausgeführte Scheiben, die aus zwei oder mehreren Glasscheiben zusammengeklebt sind. Solchermaßen verstärkte Glasscheiben bieten auch einen gewissen Schutz vor Fremdeinflüssen. Aus Verbundglasscheiben aufgebaute Wand- aber insbesondere Decken- oder Dachabschnitte kamen aber wegen der fehlenden inhärenten Verstärkung gegen Biegebelastungen aus Sicherheitsgründen bisher niemals ohne zusätzliche Stütz- oder Rahmenelemente aus. Würde man ein selbsttragendes Dachelement aus Verbundglasscheiben herstellen, so könnten diese die strengen Anforderungen bezüglich Biegebelastbarkeit zum Schutz von sich darunter befindlichen Personen nicht erfüllen. Daher sind Techniker seit langem auf der Suche nach Lösungen, wie Glasbauelemente so stabil ausgeführt werden können, daß sie auch unter hohen Biegelasten ohne die optisch störenden Rahmen- oder Stützelemente aus Metall oder dergleichen undurchsichtigem Material auskommen können. Dieses lang bestehende Problem ist nun in überraschend einfacher Weise durch die Erfindung gelöst.Laminated glass panes are therefore already known, i. H. largely executed plan Panes glued together from two or more panes of glass. thus Reinforced glass panes also offer some protection against external influences. Out Laminated glass panes built up wall but especially ceiling or roof sections came out because of the lack of inherent reinforcement against bending loads For safety reasons, never without additional support or frame elements. Would you could make a self-supporting roof element from laminated glass panes, so this could the strict requirements regarding flexural strength to protect themselves from it do not meet people. Therefore, technicians have been looking for a long time Solutions such as glass components can be made so stable that they can be used even under high Bending loads without the optically disruptive frame or support elements made of metal or the same opaque material can get by. This longstanding problem is now solved in a surprisingly simple manner by the invention.

Aus den erfindungsgemäßen Glasbauelementen läßt sich somit erstmals ein selbsttragender Decken- oder Dachabschnitt oder eine selbsttragende Decken- oder Dachkonstruktion bilden, wie er beziehungsweise sie Gegenstand des nebengeordneten Anspruchs ist, der beziehungsweise die nahezu vollständig aus Glas aufgebaut werden kann und dennoch keine Bedenken wegen der Sicherheit von sich darunter befindenden Personen aufkommen läßt. A self-supporting can thus be made for the first time from the glass components according to the invention Form a ceiling or roof section or a self-supporting ceiling or roof structure, how he or she is the subject of the subsidiary claim, the or which can be made almost entirely of glass and yet none Concerns about the safety of people below.

Oft ist es auch erwünscht, daß das Glasbauelement nicht klarsichtig ist, sondern bestimmte Schmuckdekore aufweist. In solchen Fällen kann das erste Teilelement auch aus einer Mischform der erfindungsgemäß vorgesehenen Glasmaterialien, also zum Beispiel mit Ornamenten versehenes vorgespanntes Glas, bestehen. It is often desirable that the glass component is not clear-sighted, but certain Has decorative decors. In such cases, the first sub-element can also consist of a Mixed form of the glass materials provided according to the invention, for example with Tempered glass with ornaments.

Das erfindungsgemäße Glasbauelement dient insbesondere zum Aufbau von Dach- oder Deckenabschnitten, dh. von breitflächigen Gebäudeabschnitten. Wegen der gerade bei Dach- oder Deckenabschnitten notwendigen großflächigen Belastbarkeit gegenüber Biegebelastungen sind Ausführungen des Glasbauelements vorteilhaft, bei denen ein die Breitfläche tragender Bereich des ersten Teilelements, also beispielsweise der Steg eines L- oder U-förmigen Glasprofilelements, verstärkt ist. Dies wird bei einer vorteilhaften Ausgestaltung der Erfindung dadurch erreicht, daß das zweite Teilelement eine vorzugsweise ebene Oberfläche hat, die plan- oder flächenparallel (auch gebogene Flächen sind im Prinzip denkbar) zu der Breitfläche des ersten Teilelements und vorzugsweise eng benachbart zu dieser angeordnet ist, wobei das Klebe- oder Verbundmittel die vorzugsweise ebene Oberfläche ganzflächig mit der Breitfläche fest verbindet. Auf diese Weise wird der die Breitfläche tragende Bereich des ersten Teilelements erstens durch das Klebe- oder Verbundmittel und zweitens durch das damit angeklebte zweite Teilelement verstärkt.The glass component according to the invention is used in particular to build roof or Ceiling sections, ie. of broad sections of the building. Because of the or ceiling sections necessary to withstand large loads against bending loads Versions of the glass component are advantageous in which a wide area load-bearing area of the first sub-element, for example the web of an L-shaped or U-shaped one Glass profile element, is reinforced. In an advantageous embodiment of the Invention achieved in that the second sub-element has a preferably flat surface has the plane or surface parallel (curved surfaces are also conceivable in principle) to the Broad area of the first sub-element and preferably arranged closely adjacent to it, wherein the adhesive or composite means the preferably flat surface with the entire surface Broad area firmly connects. In this way, the area of the first sub-element firstly by the adhesive or composite agent and secondly by the second sub-element glued with it reinforced.

Besonders stabil wird das Glasbauelement, wenn zwei Glasprofilelemente aneinander verklebt werden, wenn also auch das zweite Teilelement ein Glasprofilelement ist. The glass component becomes particularly stable when two glass profile elements are glued together be, so if the second sub-element is a glass profile element.

Oft ist eine unsichtbare Verstärkung des Glasbauelements erwünscht. Eine solche ist einfach dadurch realisierbar, daß das zweite Teilelement an die Rückseite des ersten Teilelements und insbesondere in die Profilform des ersten Teilelements an- bzw. eingepaßt an- bzw. eingeklebt wird. Hierzu ist als bevorzugte Ausführung vorgesehen, daß das das zweite Teilelement bildende Glasprofilelement gegenüber dem das erste Teilelement bildenden Glasprofilelement verkleinert ausgeführt ist. Wie das erste Teilelement kann auch das zweite Teilelement im Querschnitt U-förmig mit zwei Schenkeln und einem Steg dazwischen oder L-förmig mit einem Steg und nur einem Schenkel sein. Dabei können die beiden das erste und das zweite Teilelement bildenden Glasprofilelemente verschieden zueinander angeordnet sein. Bei einer Ausführung liegen nur ihre Stege aneinander und sind mittels des Klebe- oder Verbundmittels miteinander breitflächig fest verbunden. Bei einer weiteren sind die beiden Teilelemente sowohl mit ihren Stegen als auch mit einem oder mehreren Schenkeln aneinanderliegend verbunden. Dabei sind Ausführungen denkbar, bei denen die Schenkel der die Teilelemente bildenden Glasprofilelemente gleichgerichtet zueinander sind oder in entgegengesetzte Richtungen weisen. Die Profilierungen von die Teilelemente bildenden Glasprofilelementen können auch um eine senkrecht zu den Stegen oder der Breitfläche verlaufende Achse um beliebige Winkel verdreht zueinander sein. Invisible reinforcement of the glass component is often desirable. Such is easy realizable in that the second sub-element on the back of the first sub-element and in particular in the profile shape of the first sub-element becomes. For this purpose, it is provided as a preferred embodiment that the second partial element forming glass profile element compared to the glass profile element forming the first partial element is made smaller. Like the first sub-element, the second sub-element can also be in the Cross section U-shaped with two legs and a bridge in between or L-shaped with a bridge and only one leg. The two can do the first and the second Glass element elements forming part element can be arranged differently from one another. At a Execution only their webs lie against each other and are by means of the adhesive or compound firmly connected to one another over a wide area. In another, the two sub-elements are both with their webs as well as with one or more legs adjacent to each other connected. Designs are conceivable in which the legs of the partial elements forming glass profile elements are aligned with each other or in opposite Show directions. The profiling of glass profile elements forming the sub-elements can also around an axis perpendicular to the webs or the wide area any angle can be twisted to each other.

Ein sehr stabiles Glasbauelement ist erzielbar, wenn beide Teilelemente mit ihren von den Schenkel wegweisenden Breitflächen mittels des Klebe- oder Verbundmittels fest aneinander verklebt sind. Vorzugsweise, weil kostengünstig herstellbar, sind dabei die beiden Teilelemente identisch ausgebildete Glasprofilelemente. Die stabilste Form ergibt sich in einem solchen Falle dann, wenn beide Teilelemente U-förmige Glasprofilelemente sind. Ein so ausgeführtes Glasbauelement besitzt im Querschnitt beispielsweise eine Doppel-T-Profilform; selbstverständlich können die beiden Glasprofilelemente auch um eine senkrecht zu den Stegen verlaufende Achse um 90° verdreht zueinander sein, so daß die Schenkel des ersten Teilelements für eine Verstärkung gegen Biegebelastungen in der einen und die Schenkel des zweiten Teilelements für eine Verstärkung gegen Biegebelastungen in der Richtung sorgen. Wenn das zweite Teilelement als Glasprofilelement ausgebildet ist, so sind neben Floatglas oder Klarglas, Drahtglas und Walzglas als Glasmaterialen selbstverständlich auch alle Materialen denkbar, die auch für das als Glasprofilelement ausgebildete erste Teilelement denkbar sind, wobei die Glasmaterialien für Stege und Schenkel auch unterschiedlich gewählt sein können. Außerdem sind auch Ausgestaltungen der Erfindung denkbar, bei denen die beiden Teilelemente aus unterschiedlichen Glasmaterialien gebildet sind, wobei beispielsweise das sichtbare Teilelement Ornamentglas und das weniger gut sichtbare Teileelement vorgespanntes Glas aufweist. A very stable glass component can be achieved if both sub-elements with their own Legs of broad areas pointing firmly to one another by means of the adhesive or compound are glued. The two are preferred because they are inexpensive to produce Sub-elements of identical glass profile elements. The most stable form results in such a case when both sub-elements are U-shaped glass profile elements. Such a executed glass component has, for example, a double T-profile shape in cross section; of course, the two glass profile elements can also be perpendicular to the Web axis extending 90 ° to each other so that the legs of the first Partial element for reinforcement against bending loads in one and the legs of the second sub-element to provide reinforcement against bending loads in the direction. If the second sub-element is designed as a glass profile element, so are next to float glass or of course clear glass, wire glass and rolled glass as glass materials Materials conceivable that also for the first partial element designed as a glass profile element are conceivable, the glass materials for webs and legs also being chosen differently could be. In addition, embodiments of the invention are also conceivable in which the two sub-elements are formed from different glass materials, for example the visible part element ornamental glass and the less visible part element has tempered glass.

Das zweite Teilelement muß aber nicht unbedingt als Glasprofilelement ausgebildet sein, da es für bestimmte Anwendungen ausreicht, wenn nur das erste Teilelement eine Profilform aufweist. Das zweite Teilelement ist dann vorzugsweise eine vorzugsweise ebene Platte oder Scheibe. Wegen der Homogenität bei Ausdehnungen aufgrund von Temperaturschwankungen und der meist erwünschten Materialhomogenität aufgrund der optischen Erscheinung ist bevorzugt, wenn das zweite Teilelement eine Glasscheibe ist. Die Glasscheibe kann dabei beispielsweise aus den Materialien bestehen, die oben als bevorzugte Materialien für Glasprofilelemente erwähnt worden sind. Ein zusätzlich bei Glasscheiben als zweiten Teilelement mögliches Material ist Verbundscheibensicherheitsglas, wobei wiederum als Materialien für einzelne Scheibenelemente des Verbundscheibensicherheitsglases auch die oben als bevorzugte Materialien für Glasprofilelemente genannten verwendbar sind. Das als Glasscheibe vorzugsweise eben (auch gekrümmte Formen sind denkbar) ausgeführte zweite Teilelement kann dabei mittels des Klebe- oder Verbundmittels auf die Innenfläche oder auf die Außenfläche des Steges des L- oder U-förmig ausgeführten ersten Teilelements geklebt sein.The second sub-element does not necessarily have to be Glass profile element to be designed as it is for certain Applications is sufficient if only the first sub-element has a profile shape. The second sub-element is then preferably a preferably flat plate or disc. Because of the homogeneity of expansion due to temperature fluctuations and the most desired material homogeneity due to the visual appearance it is preferred if the second sub-element is a glass pane. The glass pane can be made of materials, for example consist of the above as preferred materials for Glass profile elements have been mentioned. An additional possible material for glass panes as a second sub-element is laminated safety glass, whereby again as materials for individual pane elements of laminated safety glass also the one preferred above Materials used for glass profile elements can be used are. That as a glass pane preferably flat (also curved shapes are conceivable) executed second sub-element can by means of the adhesive or composite on the inner surface or on the outer surface of the web of the L-shaped or U-shaped first partial element be glued.

Noch stärker wird das erfindungsgemäße Glasbauelement dann, wenn drei oder mehr Teilelemente aneinander verklebt sind. Demgemäß ist nach einer besonders vorteilhaften Ausgestaltung der Erfindung ein drittes Teilelement vorgesehen, das mittels des Klebe- oder Verbundmittels breitflächig mit dem ersten oder dem zweiten Teilelement verklebt ist. Eine Ausführung zum Schaffen einer durchgehenden Flächenform ohne Unterbrechungen, die aber dennoch äußerst stabil ist, wird dann geschaffen, wenn das zweite Teilelement eine großflächige Glasscheibe ist, an deren eine - eben ausgeführte - Oberfläche das erste, das dritte und vorzugsweise auch weitere Teilelemente nebeneinanderliegend mittels des Klebe- oder Verbundmittels angeklebt sind. Bevorzugt sind dabei das dritte und ggf. die weiteren Teilelemente identisch wie das erste Teilelement ausgeführt. Am stabilsten wird ein solches Gebilde dann, wenn als Querschnittsform für die aufgeklebten Teilelemente eine U-Form gewählt wird. Ganz großflächige stabile Glasflächen sind dann bildbar, wenn mehrere Reihen Teilelemente auf die großflächige Glasscheibe geklebt werden. Um eine durchgehende gerade Bruchlinie zu vermeiden, sollten aber die Teilelemente in mehreren Reihen jeweils versetzt zueinander aufgeklebt werden.The glass component according to the invention becomes even stronger then when three or more sub-elements are glued together are. Accordingly, it is particularly advantageous Embodiment of the invention, a third sub-element provided that by means of the adhesive or composite broadly with the first or the second partial element is glued. A version for creating a continuous Surface shape without interruptions, but still is extremely stable, is created when the second Partial element is a large glass pane, on the one - just executed - surface the first one third and preferably also further sub-elements lying side by side by means of the adhesive or compound are glued on. The third and possibly the other sub-elements are identical to the first sub-element executed. Such a structure is the most stable then when as a cross-sectional shape for the glued Sub-elements a U-shape is selected. Very large area stable glass surfaces can be formed if several Rows of partial elements glued to the large glass pane become. To a continuous straight fault line but should avoid the sub-elements in several rows be stuck on offset to each other.

Selbstverständlich sind aber auch Ausführungen denkbar, bei denen das zweite Teilelement - in Ausführung als Glasprofilelement oder als ebene Platte - an eine Seite des ersten Teilelements angeklebt ist und das dritte Teilelement - wählbar als Platte oder als Glasprofilelement ausgeführt - an eine der ersten Seite entgegengesetzt angeordnete zweite Seite des ersten Teilelements geklebt ist. Auf diese Weise ist ein Glasbauelement mit einem Glasprofil in der Mitte geschaffen, an dessen beiden Seiten zur Verstärkung weitere Teilelemente angeklebt sind. Of course, versions are also conceivable, where the second sub-element - in execution as Glass profile element or as a flat plate - on one side of the first sub-element is glued and the third Partial element - selectable as a plate or as a glass profile element executed - opposite to the first page arranged second side of the first sub-element is glued. In this way, a glass component is included a glass profile in the middle, on the two Additional partial elements glued on for reinforcement are.

Verbundglasscheiben sollen meist klarsichtig sein, was bei dem erfindungsgemäßen Glasbauelement nicht unbedingt immer der Fall sein muß. Demgemäß sind die erfindungsgemäB als Klebe- und Verbundmittel eingesetzten doppelseitigen Klebefolien, Gießharze oder Epoxydharze auch als verstärkte und sogar dekorierte Klebematerialien denkbar. In die Gießharze können Gewebe oder Geflechte aus Fasern, insbesondere Glasfasern oder auch Draht eingebettet sein. Auch die Klebefolien können faserverstärkt sein. Es ist auch denkbar, Dekorfolien, d.h. zum Beispiel eingefärbte oder mit Mustern versehene Klebefolien zu verwenden.Laminated glass panes should mostly be clear-sighted, which is the case with the invention Glass component does not always have to be the case. Accordingly, they are double-sided adhesive films used according to the invention as adhesive and composite means, Casting resins or epoxy resins also as reinforced and even decorated adhesive materials conceivable. Fabrics or meshes of fibers, in particular glass fibers, can be placed in the casting resins or embedded wire. The adhesive films can also be fiber-reinforced. It is also conceivable, decorative foils, i.e. for example colored or patterned adhesive films to use.

Da die erfindungsgemäßen Glasbauelemente besonders hohen Biegebelastungen standhalten können, können sie auch ohne Rahmen- oder Stützelemente oder sonstige Einfassungen aus Metall oder dergleichen verwendet werden. Die erfindungsgemäßen Glasbauelemente können sogar selbst als Rahmenelemente beispielsweise für weitere erfindungsgemäß ausgeführte großflächige Glasbauelemente ausgebildet sein. Da die erfindungsgemäßen Glasbauelemente besonders stabil und bruchsicher sind, ist es erstmals auch denkbar, daß sie für Befestigungszwecke mit "Bohrungen" versehen sind, d. h. Öffnungen, welche vorzugsweise kreisförmigen Querschnitt aufweisen, die zur Aufnahme von Befestigungsmitteln, insbesondere Befestigungsbolzen oder Befestigungsschrauben geeignet sind. Ein mit erfindungsgemäBen Glasbauelementen gebildeter Gebäudeabschnitt - sei es ein Wand-, ein Decken- oder ein Dachabschnitt - kann über solche durch die Öffnungen geführte Befestigungsbolzen mit übrigen Gebäudeteilen verbunden werden. Mit den erfindungsgmäßen Glasbauelementen wäre es im Prinzip sogar denkbar, beispielsweise ein Gewächshaus zu bauen, das - mit Ausnahme von Befestigungsschrauben und Dichtelementen - vollständig aus Glas besteht Würde man ein solches Glashaus oder Gewächshaus aus den bisher bekannten Glasbauelementen aufbauen, so könnte man sich darunter befindende Personen nicht in allen Situationen vor der Gefahr durch herabfallende Splitter oder größere Bruchstücke schützen. Dies ist jedoch mit erfindungsgemäßen Glasbauelementen ohne weiteres möglich.Since the glass components according to the invention withstand particularly high bending loads can, they can also be made without frame or support elements or other borders Metal or the like can be used. The glass components according to the invention can even as frame elements, for example, for other designs according to the invention large glass components can be formed. Since the invention Glass components are particularly stable and shatterproof, it is the first time also conceivable that they are provided with "holes" for fastening purposes, d. H. Openings which preferably have a circular cross section, those for receiving fasteners, in particular fastening bolts or Fastening screws are suitable. One with glass components according to the invention formed section of the building - be it a wall, a ceiling or a roof section - can via such fastening bolts led through the openings with other parts of the building get connected. In principle, it would even be with the glass components according to the invention conceivable, for example, to build a greenhouse that - with the exception of Fastening screws and sealing elements - made entirely of glass build such a glass house or greenhouse from the previously known glass components, so you might not find people underneath in all situations from the danger Protect falling fragments or larger fragments. However, this is with the invention Glass components possible without further ado.

Als zweites Teilelement ist eine Glasscheibe 15, die eine ebene Oberfläche 16 und eine zweite, mit Ornamentierungen versehene Oberfläche 17 aufweist, vorgesehen. Die ebene Oberfläche 16 ist mittels einer Klebefolie 18 an die den Schenkeln 12, 13 abgewandte äußere Oberfläche 19 des Steges 14 geklebt. Ein zweites Glasbauelement 2 ist in Fig. 2 gezeigt. Bei dem zweiten Glasbauelement 2 ist zwischen einem ersten und einem zweiten Schenkel 22, 23 eines U-förmigen Glasprofilelements 21 als erstem Teilelement ein zweites Teilelement, das ebenfalls in Form einer Glasscheibe 25 ausgebildet ist, geklebt. Die Glasscheibe 25 ist mit ihrer ebenen Oberfläche 26 mittels Gießharz 28 auf eine zwischen den Schenkeln 22, 23 angeordnete innere Oberfläche 29 des Steges 24 des U-förmigen Glasprofilelements 21 geklebt. Somit weist die zweite Oberfläche 27 der Glasscheibe 25 in Richtung der Schenkel 22, 23.In the first glass component 1 according to FIG. 1, the first partial element is a U-shaped one Glass profile element 11 with a first leg 12, a second leg 13 and one Web 14 provided in between. A glass pane is the second sub-element 15, which has a flat surface 16 and a second surface provided with ornaments 17 has been provided. The flat surface 16 is attached to the legs 12 by means of an adhesive film 18, 13 facing away from the outer surface 19 of the web 14 glued. A second glass component 2 is shown in FIG. 2. at the second glass component 2 is between a first and a second leg 22, 23 of a U-shaped Glass profile element 21 as the first partial element, a second Partial element, which is also in the form of a glass pane 25 is formed, glued. The glass pane 25 is with their flat surface 26 by means of casting resin 28 on a inner surface arranged between the legs 22, 23 29 of the web 24 of the U-shaped glass profile element 21 glued. The second surface 27 thus faces the glass pane 25 in the direction of the legs 22, 23.

Auch bei dem in Fig. 3 gezeigten dritten Glasbauelement ist als erstes Teilelement ein U-förmiges Glasprofilelement 31 mit zwei Schenkeln 32 und 33 und einem Steg 34 dazwischen vorgesehen. Als zweites Teilelement ist jedoch nicht eine Glasscheibe sondern ein ebenfalls U-förmiges Glasprofilelement 35 mit zwei Schenkeln 36 und einem Steg 37 dazwischen vorgesehen. Das Glasprofilelement 35 ist kleiner ausgeführt als das Glasprofilelement 34 und so ausgebildet, daß es in letzteres hineinpaßt. Demgemäß liegen die Schenkel 36 des das zweite Teilelement bildenden Glasprofilelements 35 an den Innenseiten der Schenkel 32 und 33 des das erste Teilelement bildenden Glasprofilelements 31 an. Der Steg 37 kommt auf der Innenseite des Steges 34 zu liegen. Auf diese Weise ist das Glasprofilelement 35 in das Glasprofilelement 31 eingepaßt. Als Klebe- oder Verbundmittel zwischen den Glasprofilelementen 35, 31 dient ein Epoxydharz 38. Also in the third glass component shown in FIG. 3 is the first sub-element a U-shaped glass profile element 31 with two legs 32 and 33 and a web 34 provided in between.

Als Materialien für die Glasprofilelemente 11, 21, 31, 36, 61, 65, 66, 71, 75, 81, 85, 91 und 95 kommt Einscheibensicherheitsglas oder sonstwie gehärtetem Glas oder auch Mischformen der genannten Glasmaterialien mit einfachem Fensterglas, Klarglas oder Floatglas oder mit Dekoren oder Ornamenten versehenem Glas, d. h. Ornamentglas oder mit Drahtglas in Betracht. Die Glasprofilelemente 11,21,31, 36, 61, 65, 66, 71, 75, 81, 85, 91 und 95 bestehen dabei bevorzugt einstückig aus demselben Glasmaterial. Andererseits können die bei den zweiten und dritten Teilelementen 35, 65, 66 vorgesehenen Schenkel aus unterschiedlichem Glasmaterial, insbesondere stärker ausgeführtem Glasmaterial, als die bei den zweiten und dritten Teilelementen 35, 65 und 66 vorgesehenen Stege bestehen. Als Klebe- und Verbundmittel oder -materialien kommen neben Klebefolien 18, 68, 98 und Gießharzen 28 auch Epoxidharze 38 und faser- oder drahtverstärkte Klebefolien 78 in Betracht. Dabei sind im Prinzip die in Zusammenhang mit den Glasbauelementen 1 bis 7 gezeigten oder erläuterten Klebe- und Verbundmittel 18, 28, 38, 68, 78, 88, 98 untereinander austauschbar. Als Material für die Glasscheiben 15, 25, und 86 kommt neben den eben für die Glasprofile oder Glasprofilelemente 11, 21, 31, 36, 61, 65, 66, 71, 75, 81, 85, 91, 95 aufgezählten Glasmaterialien auch Verbundscheibensicherheitsglas in Betracht. Erfindungsgemäß wird wenigstens für das erste, vorzugsweise für sämtliche der Teilelemente gehärtetes Glas verwendet, insbesondere Einscheibensicherheitsglas, das aus Float- oder Klarglas durch Erhitzen auf ca. 600°C und Abschrecken mittels Kaltluft erzeugbar ist. Ein solches Einscheibensicherheitsglas weist eine erhöhte Oberflächenspannung und hierdurch eine gewisse Spannung und Elastizität auf. Außerdem kann ein solches gehärtetes Glas größeren Temperaturschwankungen ausgesetzt werden, welche sich ohne weiteres im Bereich von 80°K oder sogar darüber bewegen können. Neben Verwendung von (voll oder vollständig vorgespanntem Glas ist auch die Verwendung von teilweise vorgespannten oder auch von teilvorgespanntem Glas möglich. Die Vorspannung kann auf einzelne Teilbereiche, z. B. eine der Oberflächen, begrenzt sein; möglich ist auch eine Teilvorspannung durch Durchführen eines milderen Erhitzungs- und Abschreckungsverfahrens. Mittels der hier beschriebenen Glasbauelemente 1-3 und 6 - 9 lassen sich die Vorteile von Einscheibensicherheitsglas, von Profilbauglas und Verbundscheibensicherheitsglas miteinander verbinden, wodurch erstmalig Dach- und Deckenkonstruktionen, -abschnitte oder -elemente aus Glas erzielbar sind, die ohne spezielle Stütz-, Rahmen- oder Tragelemente auch besonders hohen Sicherheitstandards genügen.As materials for the glass profile elements 11, 21, 31, 36, 61, 65, 66, 71, 75, 81, 85, 91 and 95 comes toughened safety glass or otherwise tempered glass or mixed forms of the above Glass materials with simple window glass, clear glass or float glass or with decors or ornaments provided glass, d. H. Ornamental glass or with wire glass. The glass profile elements 11, 21, 31, 36, 61, 65, 66, 71, 75, 81, 85, 91 and 95 preferably consist of the same in one piece Glass material. On the other hand, the second and third sub-elements 35, 65, 66 provided legs made of different glass material, in particular stronger Glass material than that of the second and third sub-elements 35, 65 and 66 provided webs exist. As an adhesive and composite means or materials come alongside Adhesive films 18, 68, 98 and casting resins 28 also epoxy resins 38 and fiber or wire reinforced Adhesive films 78 into consideration. In principle, these are in connection with the Glass components 1 to 7 shown or explained adhesive and composite 18, 28, 38, 68, 78, 88, 98 interchangeable. As material for the glass panes 15, 25 and 86 comes next to the just for the glass profiles or glass profile elements 11, 21, 31, 36, 61, 65, 66, 71, 75, 81, 85, 91, 95 enumerated glass materials also laminated safety glass in Consideration. According to the invention, at least for the first, preferably for all of the Partial tempered glass is used, especially toughened safety glass that is made of Float or clear glass can be produced by heating to approx. 600 ° C and quenching with cold air is. Such a toughened safety glass has an increased surface tension and this creates a certain tension and elasticity. In addition, such a tempered glass exposed to major temperature fluctuations, which are easily in the range of Can move 80 ° K or even above. In addition to using (fully or fully biased Glass is also the use of partially toughened or even partially tempered glass possible. The bias can be applied to individual areas, e.g. Legs of surfaces, be limited; partial pre-tensioning is also possible a milder heating and deterrent process. By means of the described here Glass components 1-3 and 6 - 9 demonstrate the advantages of single-pane safety glass Connect profiled glass and laminated safety glass with each other, which is the first time Roof and ceiling constructions, sections or elements made of glass can be achieved without special support, frame or support elements also meet particularly high safety standards suffice.

Wie in Fig. 8 gezeigt, ist aber selbstverständlich auch ein ein oder mehrere der Glasbauelemente 1 - 3 und 6 - 9 aufweisender Dach- oder Deckenabschnitt 100 durch eine an Trägem 102, 103 oder dergleichen Stützelementen befestigte Einfassung 101 haltbar. Der Dach- oder Deckenabschnitt 100 setzt Fremdeinflüssen wie zum Beispiel eines Einbruchs einen hohen Widerstand entgegen. Darüber hinaus ist er auch auf Biegebelastung beanspruchbar. Insofern müßte der Träger 103 nicht besonders stabil gelagert sein, der Kraftfluß könnte auch über den Dach- oder Deckenabschnitt 100 geleitet werden.As shown in FIG. 8, however, one or more of the glass components is of course also one 1 - 3 and 6 - 9 having roof or ceiling section 100 by a bracket 102, 103 or the like support members attached bezel 101 durable. The roof or Ceiling section 100 sets a high level of external influences such as a break-in Resistance to. In addition, it can also be subjected to bending loads. insofar the carrier 103 would not have to be particularly stable, the power flow could also via the Roof or ceiling section 100 are passed.

Wie in Fig. 9 zu sehen ist es auch ohne die Einfassungen 101 aus Metall oder dergleichen Rahmenmaterial möglich, einen vollständig aus Glas gebildeten Dach- oder Deckenabschnitt 105 aus den Glasbauelementen 1 - 3 und 6 - 9 zu bilden. In dem in Fig. 9 gezeigten Ausführungsbeispiel besteht der Dach- oder Deckenabschnitt 105 aus dem ersten, zweiten und dritten Glasbauelement 1, 2 und 3. Die Stege des ersten und zweiten Glasbauelements 1 und 2 weisen dabei gleiche Abmessungen auf. Die Schenkel 12, 13 und 22, 23 sind zueinander gerichtet. Als Randeinfassungen sind zwei dritte Glasbauelemente 3 vorgesehen, die mit ihren Stegen an den Schenkeln 12, 23 bzw. 13, 22 anliegen und mit ihren Schenkeln die aus dem ersten und dem zweiten Glasbauelement 1, 2 gebildete Einheit umgreifen. Wie aus Fig. 10 zu sehen, die das in Fig. 9 eingesetzte dritte Glasbauelement 3 in perspektivischer Ansicht zeigt, sind die Stege der dritten Glasbauelemente 3 mit Öffnungen 106 zum Durchgreifen von Befestigungsmitteln, wie beispielsweise Befestigungsschrauben oder Befestigungshaken versehen. In einer weiteren nicht explizit dargestellten Ausführungsform setzen sich diese Öffnungen 106 durch die Schenkel 12, 23 bzw. 22, 13 des ersten bzw. zweiten Glasbauelements hindurch fort Auf diese Weise ist der Dach- oder Deckenabschnitt 105 mittels der nicht näher dargestellten Befestigungsschrauben oder -haken an einem benachbarten Gebäudeabschnitt befestigbar. Der Dach- oder Deckenabschnitt 105 besteht somit bis auf die Befestigungsschrauben oder -haken vollständig aus Glasmaterialien, sofern man die Klebe- und Verbundmittel oder eventuell vorhandene Drahtverstärkungen in den Glasmaterialien außer Betracht läßt. In Fig. 13 ist ein Dachabschnitt 107 gezeigt, der aus mehreren ineinandergeschachtelten Glaselementen 6 in der vierten Ausfuhrungsform gemäß Fig. 4 gebildet und mittels der dritten Glasbauelemente 3 mit der in Fig. 10 gezeigten Bauart als Rahmenelemente befestigt sind. Es ist daraus ersichtlich, daß ohne weiteres auch großflächige Dach- oder Deckenabschnitte realisierbar sind. Vorzugsweise sind die aus den Glasbauelementen 1 - 3 und 6 - 9 gebildeten Dach- oder Deckenabschnitte doppelwandig ausgeführt. Die Schenkel weisen dabei nach innen, so daß nur die Außenflächen der Stege sichtbar sind und somit einheitliche Flächen gebildet sind. Ein optisch besonders vorteilhaftes Dach- oder Deckenelement ist geschaffen, wenn zwei der sechsten Glasbauelemente 8 mit ihren Schenkeln 82, 83 zueinanderweisend ineinander verschachtelt sind. An den Außenflächen ist dabei jeweils nur die Glasscheibe 86 zu sehen, die zudem vorzugsweise mit Ornamentierungen versehen ist.As seen in FIG. 9, it is also made of metal or the like without the bezels 101 Frame material possible, a roof or ceiling section 105 formed entirely of glass to form the glass components 1 - 3 and 6 - 9. In the embodiment shown in FIG. 9 the roof or ceiling section 105 consists of the first, second and third Glass component 1, 2 and 3. The webs of the first and second glass component 1 and 2 point same dimensions. The legs 12, 13 and 22, 23 are directed towards each other. As Edge trims are provided two third glass components 3, with their webs on the Legs 12, 23 and 13, 22 abut and with their legs from the first and the grasp the second glass component 1, 2 unit formed. As seen from Fig. 10, which in Fig. 9 inserted third glass component 3 shows a perspective view, the webs are third glass components 3 with openings 106 for reaching through fasteners, such as for example, fastening screws or fastening hooks. In another Not explicitly shown embodiment, these openings 106 through the Legs 12, 23 and 22, 13 of the first and second glass component through on this The way the roof or ceiling section 105 is by means of the one not shown Fastening screws or hooks can be attached to an adjacent section of the building. The Roof or ceiling section 105 thus consists of the fastening screws or hooks completely made of glass materials, provided that the adhesive and composite material or possibly does not take into account existing wire reinforcements in the glass materials. 13 is a Shown roof section 107, which consists of several nested glass elements 6 in the fourth embodiment according to FIG. 4 and by means of the third Glass components 3 with the type shown in Fig. 10 attached as frame elements are. It can be seen from this that large roof or Ceiling sections are realizable. These are preferably made of glass components 1-3 and 6 - 9 roof or ceiling sections formed double-walled. The thigh point inwards so that only the outer surfaces of the webs are visible and thus uniform Surfaces are formed. A visually particularly advantageous roof or ceiling element is created when two of the sixth glass components 8 with their legs 82, 83 are nested in each other. There is only one on each of the outer surfaces to see the glass pane 86, which is also preferably provided with ornaments.
