Abstract
Description
Gegenstand der Erfindung ist ein Außenbauteil zum Anbau an bestehende Gebäude, in Form eines Balkons oder Wintergartens mit einer Bodenplatte und zumindest einem Schutzgeländer, wobei die Bodenplatte über Befestigungsteile mit einer Betondecke des bestehenden Gebäudes verbunden ist.The invention relates to an external component for attachment to existing buildings, in the form of a balcony or conservatory with a floor slab and at least a guardrail, the floor slab using fasteners with a concrete ceiling of the existing building.
Mit zunehmender Erhöhung des Wohnbedarfes und gestiegenen Anforderungen hinsichtlich des Komforts von Wohnungen hat es sich als notwendig erwiesen, den Wohnwert von Gebäuden durch Anbau von Balkonen oder Wintergärten zu erhöhen. Auch die Verbesserung der Qualität von Fenstern in bezug auf Isolierung hat die Tendenz zu großflächigen Fenstern und Balkons erhöht. Bei Neubauten stellt die Fertigung von Balkonen und Wintergärten keine allzu großen Probleme dar, weil diese an Decken des Wohngebäudes angesetzt werden können. In diesem Fall stellt der Balkon nur einen überkragenden Teil der Deckenplatte dar. Die Bewehrung des Balkons wird bei der Fertigung an die Deckenbewehrung angeschlossen und Balkon und Decke werden möglichst in einem Arbeitsgang betoniert. Da die Bodenplatte des Balkons also praktisch einen Teil der Decke darstellt, sind weitere konstruktive Maßnahmen nicht erforderlich. Auf die Bodenplatte, meist rechteckiger Form, sind rechtwinklige Streben aufgesetzt, die zum Anbringen des Schutzgeländers dienen bzw. dieses selbst bilden.With increasing increases in housing needs and increasing demands with regard to the comfort of apartments, it has been shown to be necessary Increase the living quality of buildings by adding balconies or conservatories. There is also a tendency to improve the quality of windows in terms of insulation increased to large windows and balconies. In new buildings, the production of balconies and conservatories are not too big of a problem because they are on ceilings of the residential building can be applied. In this case, the balcony only provides one protruding part of the ceiling slab. The reinforcement of the balcony is in the Manufacturing connected to the ceiling reinforcement and balcony and ceiling are possible concreted in one operation. Because the base plate of the balcony is practical constitutes part of the ceiling, no further structural measures are necessary. Right-angled struts are placed on the base plate, usually rectangular, which serve to attach the guardrail or form it yourself.
Deutlich schwieriger gestaltet sich dagegen der nachträgliche Anbau von Balkonen oder Wintergärten an bereits bestehende Gebäude. Das Eigengewicht des Balkons kann nicht ausschließlich über die Deckenplatte abgetragen, sondern muss über Stützen in den Baugrund abgeleitet werden. Ebenso müssen die in der durch den Balkon dargestellten Ebene verlaufenden Zug- und Querkräfte durch konstruktive Maßnahmen aufgenommen werden. Es sind also zusätzlich Zug- und Druckglieder vorzusehen, über die eine weitergehende Absicherung des Balkons gewährleistet werden kann. Darüber hinaus gilt es beim nachträglichen Anbau von Balkonen, die Fassade bzw. die Isolierungen an möglichst wenigen Stellen zu durchdringen oder gar zu entfernen. Die Gefahr der Entstehung von unerwünschten Kältebrücken ist dann aufgrund der Masse der Bauteile erheblich. Zudem können die den kraftschlüssigen Verbund zwischen Balkon und Gebäude herstellenden Bauteile im Bereich der Isolierung oder Verkleidung des Gebäudes die Kräfte nicht abtragen, wodurch es somit zu einer hohen Momentenbelastung dieser Bauteile kommen kann. Als weiteres Problem hat es sich bei bisher bekannten technischen Systemen zum nachträglichen Anbringen von Balkonen oder Wintergärten herausgestellt, dass die erforderlichen Standsicherheitsnachweise aufwendig zu erbringen sind. Auf das jeweilige Bauwerk zugeschnittene Lösungen bringen außerdem den Nachteil mit sich, dass die erforderliche Stabilität unter erheblichem Aufwand durch Rechnungen belegt werden muss. Ein Außenbauteil der eingangs beschriebenen Art wird in CH-A-686147 dargestellt.In contrast, retrofitting balconies is much more difficult or conservatories on existing buildings. The weight of the balcony can not only be removed via the ceiling slab, but must be above supports be derived into the ground. Likewise, those shown in the balcony Flat tensile and transverse forces through constructive measures be included. So there are additional tension and compression elements to be provided which can be guaranteed further protection of the balcony. About that In addition, when retrofitting balconies, the facade and the insulation also apply to penetrate or even remove in as few places as possible. The danger the formation of undesirable cold bridges is then due to the mass of Components significantly. In addition, the non-positive connection between the balcony and building components in the field of insulation or cladding Building does not dissipate the forces, which leads to a high moment load of these components can come. Another problem has arisen with previously known ones technical systems for retrofitting balconies or conservatories it was found that the required proof of stability required a lot of effort are to provide. Solutions tailored to the respective building also bring the disadvantage that the required stability with considerable effort must be supported by invoices. An external component of the beginning described type is shown in CH-A-686147.
Der Erfindung liegt daher die Aufgabe zugrunde, unter deutlich weniger Aufwand als bisher, stabile und im Nachhinein an vorhandene Gebäude auch mit Vorsatzschale oder Verkleidung anbaubare Außenbauteile mit Befestigungen zu schaffen. Diese sollen bauaufsichtlich zugelassen sein, so dass ein Einzelfallnachweis entfällt. Sie müssen bauphysikalischen Ansprüchen genügen.The invention is therefore based on the object, with significantly less effort than before, stable and in retrospect to existing buildings also with facing or cladding to create attachable external components with fastenings. This should be approved by the building inspectorate so that a case-by-case verification is not necessary. You need to building physics requirements meet.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass das die statische Verbindung zwischen Balkon und Gebäude herstellende Befestigungsteil als Anker ausgebildet ist, der in einer korrespondierenden Ausnehmung, vorzugsweise einem Bohrloch in der Betondecke unter Herstellung eines kraftschlüssigen Verbundes durch Klebewirkung festgelegt und an seinem freien Ende mit einem die Zugkräfte aufnehmenden Fortsatz mit geringerem Durchmesser als der Ankerkörper ausgerüstet ist.The object is achieved in that the static connection Fastening part between the balcony and the building is designed as an anchor is in a corresponding recess, preferably a borehole in the concrete ceiling with the creation of a non-positive connection through adhesive action fixed and at its free end with one absorbing the tensile forces Extension with a smaller diameter than the anchor body is equipped.
Dabei wird zum einen eine Sackbohrung zur späteren Aufnahme des Ankers, zum anderen mit derselben Bohrachse eine dahinter liegende, tiefer in das Gebäude eindringende Sackbohrung geringeren Durchmessers zur Aufnahme des Fortsatzes gefertigt. Um Anker dieser Art in der Betondecke zu fixieren, ist es weit verbreitet, aus zwei Komponenten bestehende Kleber zur Herstellung des Verbundes zwischen Anker und Betondecke zu verwenden. Es ist dabei vorgesehen, dass der Ankerkörper und/oder der Fortsatz über einen Mehrkomponentengemischmantel mit der Ausnehmungsinnenwand versehen ist, der vorzugsweise die gesamte Mantelfläche von Ankerkörper und Fortsatz umhüllt. Beide Komponenten werden dabei unmittelbar vor dem Einsetzen des Ankers in das Loch eingesetzt. Durch das Einführen des rotierenden Ankers werden die beiden Komponenten des Klebstoffes dann so miteinander vermischt, dass sie miteinander reagieren und der gehärtete Klebstoff gebildet wird. Der Fortsatz ist aufgrund seines geringen Durchmessers so in die Betondecke eingefügt und vom Beton umgeben, dass er vor allem die notwendigen Zugkräfte aufnehmen kann. Die übrigen Kräfte werden sicher vom im Durchmesser dickeren Ankerkörper aufgenommen. Eine sichere Fixierung des Balkons an der vorhandenen Decke ist so erreicht. Als Ausführungsformen sind dabei denkbar, dass Ankerkörper und Fortsatz zusammen oder getrennt mit demselben oder verschiedenen Mehrkomponentengemischen beaufschlagt werden. Somit sind auf die jeweiligen Erfordernisse abstimmbare Lösungen möglich. Vorzugsweise werden Anker und Fortsatz getrennt mit zwei Patronen verschiedenen Durchmessers und Klebern unterschiedlicher Konsistenz fixiert. Dem Ankerkörper kommt vor allem die Aufgabe zu, radial wirkende Kräfte aufzunehmen, während der Fortsatz in erster Linie durch axial wirkende Kräfte beansprucht wird, womit die ihn auf Zug belastenden Kräfte abgeleitet werden. Durch die Wahl des geringen Durchmessers ist - wie oben erwähnt - gewährleistet, dass eine ausreichende Betonüberdeckung vorhanden und der Ankerkörper somit sicher eingebunden ist.On the one hand, a blind hole is used to later accommodate the anchor, on the other hand, with the same drilling axis behind it, deeper into the building penetrating blind hole of smaller diameter made to accommodate the extension. In order to fix this type of anchor in the concrete ceiling, it is widely used two-component adhesive to create the bond between anchor and concrete ceiling. It is provided that the anchor body and / or the extension over a multi-component mixture jacket with the recess inner wall is provided, which preferably the entire outer surface of the anchor body and Process encased. Both components are used immediately before the Anchor inserted into the hole. By inserting the rotating anchor, the Both components of the adhesive are then mixed together so that they are together react and the hardened adhesive is formed. The extension is due its small diameter inserted into the concrete ceiling and surrounded by the concrete, that above all it can absorb the necessary tractive forces. The remaining powers will safely absorbed by the thicker anchor body in diameter. A safe one This fixes the balcony to the existing ceiling. As embodiments are conceivable that the anchor body and extension together or separately the same or different multicomponent mixtures. Consequently solutions that can be tailored to the respective requirements are possible. Preferably anchor and extension are separated with two cartridges of different diameters and adhesives of different consistency. The anchor body comes first the task to absorb radial forces, while the extension in the first Line is stressed by axial forces, which pulls him stressful forces are derived. By choosing the small diameter is - As mentioned above - ensures that there is sufficient concrete cover and the anchor body is thus securely integrated.
Um den nötigen kraftschlüssigen Verbund zwischen Anker und Fortsatz zu sichern, wird der Fortsatz in einer bevorzugten Ausführungsform an den Anker angeschweißt oder aufgeschraubt und dann wiederum vorzugsweise über eine Schweißnaht gesichert. Eine besonders kostengünstige Ausführungsform ist dabei die Verwendung von handelsüblichen, die ermittelten Zugkräfte aufnehmenden Dübeln als Fortsatz. Diese Dübel besitzen den Vorteil, dass sie statisch nachgewiesen und zugelassen sind und ein weiterer Zugkraftnachweis in Axialrichtung des Ankers bzw. des Fortsatzes nicht mehr nötig ist, weil der Fortsatz die Zugkräfte allein abtragen kann. Durch die Verwendung eines gebräuchlichen Standardbauteils lassen sich die Kosten gegenüber bisher bekannten Ausführungsformen erfreulicherweise deutlich senken. In order to secure the necessary positive connection between anchor and extension, in a preferred embodiment, the extension is welded to the anchor or screwed on and then again preferably over a weld secured. A particularly economical embodiment is the use of commercially available dowels that absorb the determined tensile forces as an extension. The advantage of these anchors is that they are statically proven and approved and a further proof of tensile force in the axial direction of the armature or the extension is no longer necessary because the extension alone can absorb the tensile forces. Through the Using a common standard component can compare the costs Fortunately, previously known embodiments significantly lower.
Zur Aufnahme der Radialkräfte dient vor allem der Ankerkörper, dessen Mantelfläche zur Erhöhung der kraftschlüssigen Wirkung zwischen Anker und Betondecke unregelmäßig geformt sein soll. In einer bevorzugten Ausführungsform ist die Mantelfläche dabei als Gewinde ausgebildet, wodurch der Widerstand des Ankers auf Zug in bekannter Art und Weise erhöht wird. Ferner handelt es sich auch bei der Ausführungsform der Mantelfläche als Gewinde um eine handelsübliche und somit kostengünstige, wobei die Länge des Gewindes vorzugsweise der des Ankerkörpers entspricht. Damit ist die Möglichkeit gegeben, über die Ankermutter, unabhängig von der Isolierungsdicke, immer einen wirksamen Verbund mit dem Mauerwerk bzw. der Decke herzustellen.The armature body and its lateral surface serve primarily to absorb the radial forces to increase the non-positive effect between anchor and concrete ceiling irregular shape. In a preferred embodiment, the outer surface is formed as a thread, whereby the resistance of the anchor to train in known way is increased. Furthermore, it is also the embodiment the lateral surface as a thread around a commercially available and therefore inexpensive the length of the thread preferably corresponds to that of the anchor body. In order to it is possible to use the anchor nut, regardless of the insulation thickness, always create an effective bond with the masonry or the ceiling.
Das erfindungsgemäße Befestigungssystem wirkt somit mechanisch gesehen als Einspannung, wobei der Ankerkörper eine die Einfassung einer Gebäudeisolierung oder Verkleidung sicherstellende Länge aufweist. Die Dicke einer Isolierung oder Verkleidung kann also variabel sein. Der Zwischenraum kann somit überbrückt werden, ohne dass er als Abstützung oder Auflagerfläche für den Ankerkörper herangezogen werden kann. Dennoch ist die sichere Verbindung von Balkon und Betondecke gegeben.The fastening system according to the invention thus acts mechanically as Clamping, the anchor body encasing a building insulation or Fairing ensures length. The thickness of an insulation or cladding can be variable. The gap can thus be bridged without that it can be used as a support or support surface for the anchor body can. Nevertheless, there is a secure connection between the balcony and the concrete ceiling.
Als Befestigung des Außenbauteils dient eine Lasche, die dem gebäudeaußenseitigen Ende des Ankers zugeordnet ist. Nachdem der Ankerkörper in das Bohrloch eingebracht ist und die Wirkung des Klebers eingesetzt hat, wird er zunächst bei einer Ausführung der Mantelfläche als Gewinde über eine erste Mutter fixiert. Anschließend wird auf das Gewinde eine Lasche, vorzugsweise ein Winkeleisen aufgesetzt, das als Befestigung des Außenbauteils dient. Der senkrechte Schenkel des Winkeleisens wird über eine zweite Ankermutter an der Gebäudeaußenwand verspannt, somit bildet sein waagerechter Schenkel das Auflager für die Balkonplatte. Auf diese Weise ist bei Einsatz von mindestens zwei Ankerkörpern ein denkbar flexibel einsetzbares Auflager für den Balkon geschaffen, zumal Stahl- oder Betonträger, Holzbalken oder sonstige Tragsysteme angeschlossen werden können. Der folglich zwischen Balkon und Hauswand entstehende Abstand ist bauphysikalisch wünschenswert, weil Wasser hier abgeleitet werden kann, ohne dass es zu Pfützenbildung und somit Durchfeuchtung der Wand kommt. Im waagerechten Schenkel des Winkeleisens ist eine mit einem in der Betonplatte fixierten Hülsendübel korrespondierende senkrechte Bohrung vorgesehen. Diesem Hülsendübel kommt die Aufgabe zu, Winkeleisen und Betonplatte zu verbinden und gleichzeitig die Betonplatte in ihrer Ebene zu fixieren. Zur einfacheren Montage ist es zweckmäßig, die Bohrung als Langloch auszubilden.A lug, which is attached to the outside of the building, is used to fasten the external component End of the anchor is assigned. After the anchor body is inserted into the borehole is and the effect of the adhesive has started, it is first at a Execution of the lateral surface as a thread fixed by a first nut. Subsequently a tab, preferably an angle iron is placed on the thread, which as Attachment of the outer component is used. The vertical leg of the angle iron is braced on the outer wall of the building via a second anchor nut, thus forming horizontal leg the support for the balcony slab. This way is in use of at least two anchor bodies a conceivably flexible support for created the balcony, especially steel or concrete beams, wooden beams or other support systems can be connected. The one between the balcony and the house wall The resulting distance is desirable in terms of building physics because water is drained off here can become, without causing puddles and thus moisture in the wall comes. In the horizontal leg of the angle iron is one with one in the concrete slab fixed sleeve dowel corresponding vertical hole provided. this The task of sleeve dowels is to connect angle iron and concrete slab and at the same time to fix the concrete slab in its plane. It is for easier assembly expedient to design the hole as an elongated hole.
Der Fortsatz weist zur Erhöhung seines Zugwiderstandes in einer bevorzugten Ausführungsform an sich bekannte konische oder flanschförmige Abschnitte auf. Weiterhin ist der Fortsatz dabei von einer Metallarmierung umgeben und mit ihr verbunden, die aufgrund ihrer gitterartigen Struktur eine verbesserte Benetzung des Dübels mit Klebstoff und somit eine Erhöhung der Klebewirkung gewährleisten soll. Ferner kann die Mantelfläche des Fortsatzes ebenso als Gewinde ausgebildet sein.The extension points in a preferred manner to increase its tensile resistance Embodiment known conical or flange-shaped sections. Farther the extension is surrounded and connected to a metal reinforcement, due to their grid-like structure, improved wetting of the dowel with adhesive and thus to increase the adhesive effect. Further the lateral surface of the extension can also be designed as a thread.
Das Durchmesserverhältnis von Fortsatz zu Anker hat sich als besonders günstig erwiesen, wenn es zwischen 1:2 und 1:4 gewählt wird, vorzugsweise im Verhältnis 1:3.The diameter ratio of the extension to the anchor has proven to be particularly favorable proven if it is chosen between 1: 2 and 1: 4, preferably in the ratio 1: 3.
