Abstract
Description
Die Erfindung betrifft einen bewehrten Dämmkörper für eine gedämmte Fertigteilwand aus Beton und Dämmung, mit mindestens einer Dämmplatte, die einseitig an der Dämmplatte befestigte, voneinander beabstandete, senkrecht zu einer ersten Flachseite der Dämmplatte angeordneten Fixierelemente aufweist, und mit mindestens einer entfernt von der Dämmplatte an den Fixierelementen befestigten Bewehrungsmatte, wobei Abstandshalter an den den Dämmplatten fernen Enden der Fixierelemente und/oder auf der der Dämmplatte abgewandten Seite der Bewehrungsmatte abgeordnet sind.The invention relates to a reinforced insulating body for an insulated prefabricated concrete wall and insulation, with at least one insulating board, which is fixed on one side of the insulating board, spaced apart, perpendicular to a first flat side of the insulating board arranged fixing elements, and with at least one remote from the insulation board The fixing elements attached reinforcing mat, wherein spacers are seconded to the insulation panels distant ends of the fixing and / or on the side facing away from the insulation board of the reinforcing mat.
Wärmegedämmte Fertigteilwände sind allgemein bekannt und zwar als einseitig gedämmte sowie als kerngedämmte Ausführungsformen. Einseitig gedämmte Fertigteilwände gibt es in verschiedenen Varianten, zum Einen als einseitig gedämmte Fertigteilwände (Wärmedämm-Verbundwand), die auf der Baustelle noch ausgegossen werden müssen, oder zum Anderen als bereits fertig im Werk hergestellte, einseitig gedämmte Fertigteilwände, bei denen die Wärmedämmung in Form von Wärmedämmplatten auf dem liegenden Beton aufgedrückt und beim Aushärten mit diesem verbunden werden. Die Herstellung derartiger Fertigteilwände ist aufwändig und ihr Transport zu der Baustelle aufgrund des Transportmaßes und des Transportgewichtes erschwert.Thermally insulated prefabricated walls are well known, namely as a one-sided insulated as well as core-insulated embodiments. Single-sided prefabricated walls are available in different variants, on the one hand as one-sided insulated prefabricated walls (thermal insulation composite wall), which still need to be poured on the site, or on the other hand as already finished in the factory, one-sided insulated prefabricated walls in which the thermal insulation in shape be pressed by thermal insulation boards on the underlying concrete and connected during curing with this. The production of such Prefabricated part walls is complex and difficult to transport to the construction site due to the transport dimension and the transport weight.
Daher ist es oft wünschenswert, Fertigteilwände komplett auf der Baustelle unter Verwendung von vorgefertigten Wärmedämmkörpern zu gießen, die bereits die Bewehrung für die Fertigteilwand aufweisen.Therefore, it is often desirable to cast prefabricated walls completely on site using prefabricated thermal insulation panels that already have the reinforcement for the precast wall.
Ein solcher bewehrter Dämmkörper gemäss dem Oberbegriff von Anspruch 1 ist aus der
Der dort vorgeschlagene Dämmkörper weist mindestens eine Dämmplatte, mindestens einseitig der Dämmplatte an dieser befestigte, voneinander beabstandete und senkrecht zu der Flachseite angeordnete Fixierelemente, mindestens eine an den Fixierelementen entfernt von der Dämmplatte an diesen befestigte Bewehrungsmatte auf, sowie Abstandshalter an den den Dämmplatten fernen Enden der Fixierelemente und/oder auf der der Dämmplatte abgewandten Seite der Bewehrungsmatte.The insulating body proposed there has at least one insulating board, at least one side of the insulating board attached to this, spaced apart and perpendicular to the flat side arranged fixing elements, at least one of the fixing elements away from the insulation board to these fixed reinforcement mat, and spacers on the insulation boards far ends the fixing and / or on the side facing away from the insulation board of the reinforcing mat.
Es ist weiterhin bekannt, Hauswände außen mit Vorsatzschalen zu verkleiden, die hinterlüftet sind. Dazu wird üblicherweise eine Tragkonstruktion für die Vorsatzschalen mit nicht rostenden Ankerelementen an der Hauswand verankert, an denen die Vorsatzschalen mit einem Abstand zur Wand befestigbar sind. Bei einseitig wärmegedämmten Fertigteilwänden ist das Anbringen der Tragkonstruktion aufgrund der geringen Festigkeit der außen angeordneten Dämmplatten und der geringen Aufnahmefähigkeit für Verankerungskräfte erschwert. Bei solchen Wänden sind dann aufwendige Verankerungen mit speziellen Ankerelementen erforderlich, die bis in die innere Betonschale hinreichen, um die Kräfte, die durch die Vorsatzschale entstehen, in die Betonschale abzutragen.It is also known to dress house walls outside with attachment shells, which are ventilated. For this purpose, usually a supporting structure for the attachment shells is anchored with stainless anchor elements on the house wall, where the attachment shells are fastened at a distance from the wall. In one-sided thermally insulated prefabricated walls mounting the support structure is difficult due to the low strength of the outside insulation boards and the low capacity for anchoring forces. In such walls then elaborate anchorages with special anchor elements are required, which extend into the inner concrete shell to remove the forces that arise through the facing shell in the concrete shell.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Möglichkeit vorzuschlagen, bei der die Anbringung einer Vorsatzschale an einer Wärmedämm-Verbundwand vereinfacht ist und die es darüber hinaus erlaubt, gedämmte Fertigteilwände mit einer Tragkonstruktion einfach auf der Baustelle herzustellen.The invention is therefore based on the object to propose a possibility in which the attachment of an attachment shell is simplified to a composite thermal insulation wall and it also allows to produce insulated prefabricated walls with a support structure easy on the site.
Diese Aufgabe wird erfindungsgemäß durch einen bewehrten Dämmkörper mit den Merkmalen des Anspruchs 1 und durch eine Fertigteilwand mit diesem bewehrten Dämmkörper mit den Merkmalen des Anspruchs 7 gelöst, sowie durch ein Verfahren zur Herstellung derselben nach den nebengeordneten Verfahrensanspruch 9. Weitere vorteilhafte Ausgestaltungen sind den jeweiligen rückbezogenen Unteransprüchen zu entnehmen.This object is achieved by a reinforced insulating body with the features of
Gemäß der Erfindung weist die Dämmplatte des bewehrten Dämmkörpers an einer zweiten Flachseite, die einer ersten Flachseite der Dämmplatte mit daran angeordneten Fixierelementen und mindestens einer an diesen befestigten Bewehrungsmatte gegenüberliegt, eine Tragkonstruktion auf, die mit Ankerelementen an der Dämmplatte befestigt ist, wobei die Ankerelemente über die erste Flachseite der Dämmplatte vorstehen. Dies ermöglicht nach der Herstellung der einseitig wärmegedämmten Fertigteilwand jede Art von Vorsatzschale, beispielsweise aus Ziegel, Holz, Klinker, Naturstein oder Plattenwerkstoffen, direkt an der Fertigteilwand anzubringen, ohne dafür zusätzliche bzw. nachträgliche Verankerungen vorzunehmen. Die Kräfte, die durch die Vorsatzschale entstehen und von der Betonschale aufgenommen werden müssen, werden durch spezielle Verankerungselemente, die im bewehrten Dämmkörper bereits integriert sind, abgetragen. Diese Verankerungselemente weisen vorzugsweise geringe Wärmeleitfähigkeiten auf, um die konstruktionsbedingten Wärmebrücken so niedrig wie möglich zu halten.According to the invention, the insulating board of the reinforced insulating body on a second flat side, which faces a first flat side of the insulating board with fixing elements disposed thereon and at least one reinforcing mat attached thereto, a supporting structure which is secured with anchor elements on the insulating board, wherein the anchor elements via protrude the first flat side of the insulation board. This allows after the production of one-sided thermally insulated precast wall any kind of facing shell, for example, brick, wood, clinker, natural stone or board materials to install directly on the precast wall, without making additional or subsequent anchorages. The forces that arise through the facing shell and must be absorbed by the concrete shell are removed by special anchoring elements that are already integrated in the reinforced insulating body. These anchoring elements preferably have low thermal conductivities in order to keep the design-related thermal bridges as low as possible.
Der bewehrte Dämmkörper weist mindestens eine Dämmplatte auf, an deren einer Betonschale zugeordneten ersten Flachseite voneinander beabstandete und senkrecht zu der Flachseite angeordnete Fixierelemente befestigt sind. Die Fixierelemente verlaufen im Wesentlichen über die gesamte Breite der Flachseite und können das übliche Gitterträgerprofil aufweisen. Wichtig ist dabei, dass die Fixierelemente stabil an der Dämmplatte befestigt sind, um die Dämmplatte später beim Betonieren zu fixieren. Des Weiteren weist der bewehrte Dämmkörper mindestens eine an den Fixierelementen entfernt von der Dämmplatte angeordnete Bewehrungsmatte auf. Die Bewehrungsmatte kann an den der Dämmplatte fernen Enden oder in einem mittleren Bereich der Fixierelemente befestigt sein. Außerdem weist der bewehrte Dämmkörper noch Abstandshalter an den den Dämmplatten fernen Enden der Fixierelemente und/oder auf der den Dämmplatten abgewandten Seiten der Bewehrungsmatte auf, um damit einen Abstand zu der äußeren Oberfläche der späteren Betonwand herzustellen.The reinforced insulating body has at least one insulating board, at whose concrete shell associated first flat side spaced apart and perpendicular to the flat side arranged fixing elements are attached. The fixing elements extend substantially over the entire width of the flat side and may have the usual lattice girder profile. It is important that the Fixing elements are stably attached to the insulation board to fix the insulation board later during concreting. Furthermore, the reinforced insulating body has at least one reinforcing mat arranged at a distance from the fixing plate on the fixing elements. The reinforcing mat may be attached to the ends of the insulation board or in a central region of the fixing elements. In addition, the reinforced insulating body still has spacers on the ends of the fixing elements remote from the insulating panels and / or on the sides of the reinforcing mat facing away from the insulating panels so as to make a distance from the outer surface of the later concrete wall.
Vorzugsweise weist der bewehrte Dämmkörper Fixierelemente mit einer Tragplatte auf, die an der Dämmplatte anliegen, wobei an der Tragplatte in Richtung Dämmplatte weisende Eingriffskanten für den Eingriff in entsprechende Nuten in der Dämmplatte ausgebildet sind. Damit sind die Fixierelemente sicher und kräfteübertragend an der Dämmplatte fixierbar, so dass die Dämmplatte nach dem Betonieren der Fertigteilwand fest mit deren Betonschale verbunden ist.Preferably, the reinforced Dämmkörper has fixing elements with a support plate, which rest against the insulation board, being formed on the support plate in the direction of insulation board facing engagement edges for engagement in corresponding grooves in the insulation board. Thus, the fixing elements are securely and force-transferable to the insulation board fixable, so that the insulation board is firmly connected after concreting the precast concrete wall with their concrete shell.
Gemäß einer bevorzugten Ausbildung des erfindungsgemäßen bewehrten Dämmkörpers sind die Fixierelemente mit der Dämmplatte verklebt. Dies ermöglicht eine einfache schnelle und sichere Verbindung der Fixierkörper mit der Dämmplatte bei der Herstellung des Dämmkörpers.According to a preferred embodiment of the reinforced insulating body according to the invention, the fixing elements are glued to the insulation board. This allows a simple fast and secure connection of the fixing with the insulation board in the manufacture of the insulating body.
Vorteilhafterweise weist die Tragkonstruktion des Dämmkörpers voneinander beabstandete Träger auf. Die Träger liegen an der Dämmplatte in Anlage und werden von den Ankerelementen gehalten. Bei den Ankerelementen handelt es sich um bekannte, aus Metall oder Kunststoff oder Kohlefasern bestehende im Wesentlichen zylindrische Traganker. Auf die mittels der Ankerelemente befestigten Träger können weitere, quer dazu verlaufende Querträger vorgesehen sein, die in einem bestimmten Abstand zueinander angeordnet sind. Der Abstand der Querträger wird im Wesentlichen durch die Maße der an der Fertigteilwand anzubringenden Vorsatzschalenelemente bestimmt.Advantageously, the support structure of the insulating body on spaced apart carrier. The carriers are in contact with the insulation board and are held by the anchor elements. The anchor elements are known, consisting of metal or plastic or carbon fibers substantially cylindrical support anchor. On the carrier fixed by means of the anchor elements further, transverse thereto extending cross member may be provided, which are arranged at a certain distance from each other. The distance between the cross members is determined essentially by the dimensions of the attachment shell elements to be attached to the precast wall.
Gemäß einer anderen bevorzugten Ausbildung der Erfindung liegen die Träger der Tragkonstruktion in Nuten der Dämmplatte mit einem Überstand ein. Durch das Versenken der Träger in der Dämmplatte kann die Vorsatzschale in einem geringen Abstand zu der Dämmplatte an der Fertigteilwand befestigt wären. Der Überstand der Träger gegenüber der Dämmplatten ist dabei so gewählt, dass eine ausreichende Hinterlüftung der Vorsatzschale sichergestellt ist.According to another preferred embodiment of the invention, the support of the support structure lie in grooves of the insulation board with a supernatant. By sinking the support in the insulation board, the facing shell would be attached at a small distance from the insulation board to the precast wall. The supernatant of the carrier with respect to the insulation boards is chosen so that a sufficient ventilation of the facing shell is ensured.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist der bewehrte Dämmkörper als Gesamtheit beweg- und transportierbar, so dass er auch auf der Baustelle zwischen vertikal angeordneten Schalungstafeln einsetzbar ist. Der bewehrte Dämmkörper kann auch im Werk oder auf der Baustelle hergestellt und/oder weiter verarbeitet werden. Er kann entweder in eine vorhandene Batterieschalung oder in eine aus einzelnen Schalungsteilen zusammengestellte Schalungswand mit vertikal angeordneten Schalungszwischenräumen stehend eingesetzt werden. Natürlich kann der bewehrte Dämmkörper auch liegend in eine horizontal ausgerichtete, nach oben offene Schalungsform für eine Wärmeverbundwand eingebracht werden.According to a particularly advantageous embodiment of the invention, the reinforced insulating body as a whole is movable and transportable, so that it can also be used on the construction site between vertically arranged formwork panels. The reinforced insulating body can also be manufactured and / or further processed in the factory or on the construction site. It can be used standing either in an existing battery formwork or in a formwork wall composed of individual formwork parts with vertically arranged formwork intermediate spaces. Of course, the reinforced insulating body can also be placed horizontally in a horizontally oriented, upwardly open mold for a thermal composite wall.
Die erfindungsgemäße Fertigteilwand, mit oder ohne Vorsatzschale, ist unter der Verwendung eines Dämmkörpers mit den vorgehend beschriebenen Merkmalen hergestellt. In einen sich im Wesentlichen vertikal erstreckenden Schalungsraum kann das Einbringen der Dämmkörpers stehend von oben her erfolgen oder bei seitlich noch nicht geschlossen Schalungsraum von der Seite her, bevor der Schalungsraum seitlich verschlossen wird. Der Dämmkörper wird vor dem Betonieren der Fertigteilwand in dem Schalungsraum derart fixiert, dass er sich mit den Trägern oder Querträgern der Tragkonstruktion an den Schalungstafeln abstützen kann. So ist es möglich, eine einseitig gedämmte Fertigteilwand mit Tragkonstruktion in einer senkrechten Stellung herzustellen, wobei der freie Schalungsraum zwischen dem eingesetzten Dämmkörper und den Schalungstafeln, in dem sich die Fixierelemente, die Bewehrungsmatte und die Ankerelemente erstrecken, von oben her mit Ortbeton verfüllbar ist.The prefabricated part wall according to the invention, with or without facing shell, is produced by using an insulating body with the features described above. In a substantially vertically extending formwork space, the introduction of the insulating body can be done standing from above or laterally not closed formwork space from the side before the shuttering space is closed laterally. The insulating body is fixed in such a way before concreting the precast wall in the formwork space that it can be supported on the formwork panels with the carriers or cross members of the support structure. Thus, it is possible to produce a one-sided insulated prefabricated wall with supporting structure in a vertical position, wherein the free formwork space between the insulating body used and the formwork panels in which extend the fixing, the reinforcement mat and the anchor elements, can be filled from above with in-situ concrete.
In einem sich horizontal erstreckende, nach oben offene Schalungsform für eine Wärmeverbundwand kann der Dämmkörper auch liegend verwendet werden. Dabei kann der Dämmkörper, mit nach oben weisender Tragkonstruktion von oben in die Schalungsform eingesetzt werden, wenn diese noch nicht, teilweise oder vollständig mit Ortbeton gefüllt ist. Der Dämmkörper kann auch zuerst mit nach unten weisender Tragkonstruktion in die Schalungsform eingesetzt werden und der Schalungsraum anschließend mit Ortbeton verfüllt werden. Zur fehlerfreien Herstellung der Wärmeverbundwand ist es hilfreich, den Ortbeton bzw. den Dämmkörper oder die Schalungsform zu rütteln und Dämmkörper an der Schalungsform zu fixieren.In a horizontally extending, upwardly open form of form for a thermal composite wall, the insulating body can also be used lying. In this case, the insulating body can be used with upwardly facing support structure from above into the formwork form, if this is not yet, partially or completely filled with in-situ concrete. The insulating body can also be used first with downwardly facing support structure in the formwork and the shuttering space then be filled with in-situ concrete. For faultless production of the thermal composite wall, it is helpful to shake the in-situ concrete or the insulating body or the formwork and to fix insulating body to the formwork.

- 3. introducing the insulating body in the Vergussraum and fixing in the Vergussraum;
- 4. filling the cavity formed between the insulating body and the shuttering with in-situ concrete from above; and
- 5. Compacting the in-situ concrete.
Es hat sich als zweckmäßig erwiesen, den Vergussraum für das Einbringen des Dämmkörpers einseitig an einer Flach- oder Stirnseite offen zu lassen und erst dann zu verschließen, wenn der Dämmkörper in den Vergussraum eingebracht, ausgerichtet und fixiert ist. Dies erleichtert die dabei notwendigen Arbeiten.It has proved to be expedient to leave the casting space for the introduction of the insulating body unilaterally on a flat or front side open and only to close when the insulating body is introduced into the Vergussraum, aligned and fixed. This facilitates the necessary work.

Das senkrechte Herstellen der Wände direkt an der Baustelle reduziert den Arbeitsaufwand und darüber hinaus auch die Transportkosten.With the inventively designed reinforced insulating body insulated prefabricated walls can be made with formwork smooth inner walls and with a support structure for facing shells on the outer walls for direct further processing.
