Description

Die Erfindung bezieht sich auf eine Gebäudewand mit einer darin ausgebildeten Öffnung für ein Fenster oder eine Tür, mit einem geschichteten Wandaufbau aus einer Außenwandschale, einer im Abstand dazu angeordneten Innenwandschale und einer zwischen den vorgenannten Wandschalen angeordneten, an den Wandschalen vollflächig anliegenden Wärmeisolierplatte.The invention relates to a building wall with an opening formed therein for a window or a door, with a layered wall structure of an outer wall shell, a spaced apart inner wall shell and arranged between the aforementioned wall shells, on the wall shells full-surface adjacent Wärmeisolierplatte.

Gebäudewandkonstruktionen der vorgenannten Art sind allgemein bekannt. Sie finden sich beispielsweise im Holzständerbau oder als Betonfertigteile. Der Anschluss von Fenstern oder Türen in Gebäudewänden stellt insofern ein besonderes Problem dar, als hierdurch Wärmebrücken entstehen. Mit einer Lösung hierfür beschäftigt sich beispielsweise die DE 40 40 943 A1 , die eine Vorrichtung zum Anbringen eines wärmedämmenden Isolierbelags an einer Fenster- oder Türlaibung in einer Betonwand beschreibt, mit einer zur Bildung einer Fenster- oder Türöffnung in eine Wandschalung einsetzbaren Schalung, bei der ein einbaufertiger Schalungsrahmen auf seiner Außenfläche mit einem wärmedämmenden Isolierbelag versehen ist, der vom Rahmen lösbar ist, wenn der Schalungsrahmen aus der Fenster- oder Türöffnung entfernt wird. Diese Vorrichtung nimmt allerdings auf die speziellen Probleme, die sich bei einem mehrschaligen Wandaufbau ergeben, keine Rücksicht. Im Gegenteil, der Blendrahmen selber wird unmittelbar in den Beton eingegossen und stellt daher eine mit diesem direkt verbundene Wärmebrücke dar.Building wall constructions of the aforementioned type are generally known. They can be found, for example, in timber frame construction or as precast concrete elements. The connection of windows or doors in building walls presents a particular problem insofar as this creates thermal bridges. For example, the solution deals with this DE 40 40 943 A1 document describing a device for applying a heat-insulating insulating covering to a window or door reveal in a concrete wall, with a formwork that can be used to form a window or door opening in a wall formwork, in which a ready-to-install formwork frame is provided with a heat insulating insulating covering on its outer surface, which is detachable from the frame when the shuttering frame is removed from the window or door opening. However, this device takes no account of the specific problems associated with multi-shell wall construction. On the contrary, the frame itself is poured directly into the concrete and therefore represents a directly connected to this thermal bridge.

Infolge der durch die staatlichen Verordnungen zur Energieeinsparung ausgelösten Bemühungen, die Wärmedämmung von Gebäuden zu verbessern, sind in den letzten Jahren Konzepte bekannt geworden, die mit in Gebäudewänden integrierten Vakuum-Dämmplatten oder -Paneelen arbeiten. Die von Vakuum-Paneelen geschaffene Isolation ist so gut, dass die Dicken der übrigen Elemente einer mehrschaligen Gebäudewand gegenüber den herkömmlichen Lösungen ganz beachtlich vermindert werden können. Moderne Gebäude mit einem Wärmeschutz gemäß Niedrigenergie- oder Passivhausstandard brauchten bislang eine 15 bis 30 cm dicke Wärmedämmung herkömmlicher Technologie. Das wurde besonders bei kleinen Grundstücken zum Problem. Eine Vakuum-Isolation vergleichbarer Wärmedämmung erfordert hingegen nur eine Dicke von etwa 40 mm. Sie erweitert also den nutzbaren Raum bei gleichem Gebäudegrundriss. Die Schwachstelle in solchen Konstruktionen bleibt aber noch immer der Anschluss von Fenster- oder Türrahmen, insbesondere auch deshalb, weil Vakuum-Paneele auf der Baustelle nicht mehr zurechtgeschnitten werden können, ohne ihre hervorragenden Eigenschaften, deretwegen sie eingesetzt werden, zu zerstören.As a result of the efforts made by state energy saving regulations to improve the thermal insulation of buildings, concepts have become known in recent years that work with vacuum insulation panels or panels integrated in building walls. The insulation created by vacuum panels is so good that the thicknesses of the remaining elements of a multi-skin building wall can be considerably reduced compared to conventional solutions. Up to now, modern buildings with thermal insulation according to low energy or passive house standard required a 15 to 30 cm thick thermal insulation of conventional technology. This became a problem especially for small plots. A vacuum insulation of comparable thermal insulation on the other hand only requires a thickness of about 40 mm. So it extends the usable space with the same building floor plan. However, the weak point in such constructions still remains the connection of window or door frames, in particular because vacuum panels can no longer be cut to size on the construction site without destroying their excellent properties for which they are used.

Aus der DE 100 00 643 C1 und der DE 200 00 211 U1 sind Gebäudewände bekannt, die einen dreiteiligen Zargenaufbau mit einem mittleren Isolierkörper und einem Wandaufbau mit zwei Wandschalen aus Beton und einem darwischen ligenden Dämmkern besitzen. Derartige Anordnungen können die können die immer mehr steigenden Anforderungen hinsichtlich Wärmedämmung allerdings auch nur bedingt erfüllen.From the DE 100 00 643 C1 and the DE 200 00 211 U1 Building walls are known, which have a three-part frame construction with a middle insulating body and a wall structure with two wall shells made of concrete and a Darwischen ligierenden insulating core. However, such arrangements can meet the ever increasing demands for thermal insulation but only partially.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Gebäudewand der eingangs genannten Art mit wenigstens einer Öffnung anzugeben, in die auf einfache Weise der Blendrahmen eines Fensters oder einer Tür eingesetzt werden kann, und bei der Wärmebrücken im Bereich der Fenster- oder Türöffnung noch besser vermieden sind.The present invention has for its object to provide a building wall of the type mentioned above with at least one opening into which the frame of a window or door can be used in a simple manner, and even better avoided in the thermal bridges in the window or door opening are.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by the features specified in claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Von der Erfindung wird eine Gebäudewandkonstruktion angegeben, bei der jener Bereich der Zarge für die Aufnahme eines Fensters oder einer Tür, der in dem Bereich liegt, in dem in der Wand die Wärmeisolierplatte angeordnet ist, von einem wärmeisolierenden Brückenkörper gebildet ist, an dem nach Fertigstellung der Gebäudewand der Blendrahmen eines Fensters oder einer Tür angeschlossen werden kann. Der Blendrahmen greift somit nicht in die innere Wandkonstruktion ein, wie es noch bei der Vorrichtung nach der DE 40 40 943 A1 der Fall ist. Der innere Aufbau der Gebäudewand kann unabhängig von dem in der Wandöffnung anzubringenden Fenster oder Tür fertiggestellt werden. Dabei kann man den Besonderheiten, die eine hochqualitative Wärmeisolierung erfordert, uneingeschränkt Rechnung tragen, ohne auf die spezielle Fenster- oder Türkonstruktion Rücksicht nehmen zu müssen.The present invention provides a building wall structure in which that portion of the frame for receiving a window or a door located in the area where the heat insulating plate is disposed in the wall is formed by a heat insulating bridge body after completion the building wall can be connected to the frame of a window or a door. The frame thus does not interfere with the inner wall construction, as it still in the device according to the DE 40 40 943 A1 the case is. The internal structure of the building wall can be completed independently of the window or door to be mounted in the wall opening. In doing so, it is possible to fully take into account the particularities which require a high-quality thermal insulation, without having to take account of the special window or door construction.

Wesentliche Elemente der erfindungsgemäßen Konstruktion sind ein äußerer und ein innerer Wärmeisolierkörper, die mit den äußeren und inneren Wandschalen vollflächig verbunden sind, wodurch Luftzirkulationen zwischen den Wandschalen und den Isolierkörpern unterbunden sind und ein mechanisch sicherer Anschluss der Zarge an dem Wandaufbau sichergestellt ist. Weiterhin ist ein wesentliches Element der Erfindung ein Brückenkörper, der die äußeren und inneren Wärmeisolierkörper in jenem Bereich miteinander verbindet, in dem zwischen den beiden genannten Wandschalen die Wärmeisolierplatte angeordnet ist. Die äußeren und inneren Isolierkörper können zusammen mit dem Brückenkörper zu einer integralen Einheit vereinigt sein, doch kann zu einem zusammengesetzten Aufbau gegriffen werden, dessen Einzelteile fest miteinander verbunden sind, wenn man aus Kostengründen die äußeren und inneren Wärmeisolierkörper aus einem weniger gut wärmeisolierenden und daher billigeren Material erstellen möchte als den Brückenkörper, bei dem es auf eine besonders hochwertige Isolierung ankommt zur weiteren Verbesserung der Wärmeisolierung ist zwischen der Stirnseite der Wärmeisolierplatte und dem Brückenkörper ein Dichtungsschaumstoffband eingefügt oder ein PU-Schaum eingespritzt , so dass sich zwischen der Wärmeisolierplatte und dem Brückenkörper keine Luftzirkulation einstellen kann.Essential elements of the construction according to the invention are an outer and an inner Wärmeisolierkörper, which are connected to the outer and inner wall shells over the entire surface, whereby air circulation between the wall shells and the insulating bodies are prevented and a mechanically secure connection of the frame is ensured on the wall structure. Furthermore, an essential element of the invention is a bridge body comprising the outer and inner heat insulating bodies connects in that area with each other, in which between the two said wall shells, the heat insulating is arranged. The outer and inner insulating body can be combined with the bridge body to form an integral unit, but can be used to a composite structure, the items are firmly connected together, if you for cost reasons, the outer and inner Wärmeisolierkörper from a less well heat-insulating and therefore cheaper Create material as the bridge body, where it depends on a particularly high quality insulation to further improve the thermal insulation is inserted between the front of the heat insulating and the bridge body a sealing foam tape or injected a PU foam, so that between the heat insulating and the bridge body no Air circulation can adjust.

In Weiterbildung der Erfindung hat der äußere Wärmeisolierkörper einen Falz, in den der Brückenkörper eingesetzt ist und der in Richtung auf die Wärmeisolierplatte über den Brückenkörper hinaus verlängert und gegenüber der Innenfläche der Außenwandschale zurückgesetzt ist. Der äußere Wärmeisolierkörper übergreift dadurch den Brückenkörper im gewissen Umfang, und er bildet in dem Abschnitt, der sich zwischen dem Brückenkörper und der Innenfläche der Außenwandschale erstreckt, einen weiteren Falz aus, in den ein Dichtungsschaumstoffband eingelegt ist, das an den diesen Falz begrenzenden Flächen, einschließlich der Wärmeisolierplatte, elastisch anliegt.In a further development of the invention, the outer heat insulating body has a fold in which the bridge body is inserted and which extends in the direction of the heat insulating over the bridge body out and back against the inner surface of the outer wall shell. The outer Wärmeisolierkörper thereby engages over the bridge body to some extent, and it forms in the section which extends between the bridge body and the inner surface of the outer wall shell, another fold, in which a sealing foam tape is inserted, which at the fold bordering surfaces, including the heat insulating plate, elastically applied.

Der innere Wärmeisolierkörper, der Brückenkörper und die Wärmeisolierplatte, gleichgültig, ob der innere Wärmeisolierkörper und der Brückenkörper als einteiliges Bauelement oder aus zwei gesondert hergestellten Bauelementen zusammengefügt ist, sollten an der der Wand zugewandten Seite vorzugsweise mittels eines Butyldichtungsbandes miteinander verbunden sein, an dessen den vorgenannten Bauelementen abgewandten Seite die Innenwandschale anliegt.The inner Wärmeisolierkörper, the bridge body and the Wärmeisolierplatte, regardless of whether the inner Wärmeisolierkörper and the bridge body is assembled as a one-piece component or two separately manufactured components should preferably be connected to each other on the wall side by means of a Butyldichtungsbandes, at which the aforementioned Components facing away from the inner wall shell.

Für einen mechanischen Schutz des äußeren Wärmeisolierkörpers kann dieser auf seiner Laibungsfläche mit einer Faserzementschicht bedeckt sein. Aus demselben Grunde kann der innere Wärmeisolierkörper auf seiner Laibungsfläche von einer Kunststoffschale oder einer Faserzementschicht bedeckt sein.For mechanical protection of the outer Wärmeisolierkörpers this can be covered on its soffit surface with a fiber cement layer. For the same reason, the inner Wärmeisolierkörper may be covered on its reveal surface of a plastic shell or a fiber cement layer.

Als Material für die äußeren und inneren Wärmeisolierkörper einer aus mehreren Teilen zusammengesetzten Zarge haben sich ein solches als vorteilhaft erwiesen, das aus Restwertstoffen von CO2- oder Pentan- getriebenen, FCKW-freien Hartschäumen der Dämmstoffindustrie hergestellt ist. Materialien dieser Art werden beispielsweise unter der Marke "Phonotherm" auf dem Markt angeboten. Für den Brückenkörper sollte ein hoch wärmeisolierender Hartschaum gewählt werden, den man freilich auch für die inneren und äußeren Wärmeisolierkörper verwenden kann, wenn keine Preiszwänge dagegen stehen. Die Wärmeisolierplatte ist vorzugsweise eine Vakuum-Dämmplatte.As a material for the outer and inner heat insulating a composite of several parts frame have proven to be advantageous, which is made of residual value of CO 2 - or pentane-driven, CFC-free rigid foams of the insulation industry. Materials of this kind are offered for example under the brand "Phonotherm" in the market. For the bridge body, a high heat insulating hard foam should be selected, which of course you can also use for the inner and outer Wärmeisolierkörper if there are no price constraints against it. The heat insulating plate is preferably a vacuum insulation board.

Die Erfindung wird nachfolgend unter Bezugnahme auf ein in der Zeichnung dargestelltes Ausführungsbeispiel näher erläutert.The invention will be explained in more detail with reference to an exemplary embodiment shown in the drawing.

Die Zeichnung zeigt im Querschnitt den Laibungsbereich der Öffnung in einer Gebäudewand. Man erkennt von der Gebäudewand eine äußere Wandschale 1, die im vorliegenden Falle aus Beton gegossen ist, eine innere Wandschale 2, die ebenfalls aus Beton gegossen ist, eine Wärmeisolierplatte 3 die an der Außenwandschale 1 anliegt, und eine Betonfüllung 4, die den Zwischenraum zwischen der Wärmeisolierplatte 3 und der Innenwandschale 2 ausfüllt und im Fertigzustand teil der Innenwandschale 2 bildet. Auf die Herstellungs- und Verarbeitungsverfahren wird später noch einzugehen sein.The drawing shows in cross section the soffit area of the opening in a building wall. It can be seen from the building wall an outer wall shell 1, which is cast in the present case of concrete, an inner wall shell 2, which is also cast from concrete, a heat insulating 3 which rests against the outer wall shell 1, and a concrete filling 4, the space between the heat insulating plate 3 and the inner wall shell 2 fills and in the finished state part of the inner wall shell 2 forms. The manufacturing and processing methods will be discussed later.

Die Öffnung in der Gebäudewand wird von einer Zarge Z begrenzt, die aus einem äußeren Isolierkörper 5, einem inneren Isolierkörper 6 und einem diese Isolierkörper 5 und 6 verbindenden wärmeisolierenden Brückenkörper 7 besteht. Der äußere Isolierkörper 5 und der innere Isolierkörper 6 sind mit dem Brückenkörper 7, der vorzugsweise aus einem Wärme hoch isolierenden Material besteht, fest verbunden, beispielsweise durch Verklebung, was jeweils durch drei horizontale Linien symbolisiert ist. An seiner Laibungsseite ist der äußere Isolierkörper 5 von einer Faserzementauflage 8 bedeckt, während der innere Isolierkörper 5 auf seiner Laibungsseite von einer Kunststoffschale 9 bedeckt ist, die an der Wandinnenseite um die Kante herumgezogen ist, um einen mechanischen Kantenschutz zu bilden.The opening in the building wall is bounded by a frame Z, which consists of an outer insulating body 5, an inner insulating body 6 and a heat insulating bridge body 7 connecting this insulating body 5 and 6. The outer insulating body 5 and the inner insulating body 6 are connected to the bridge body 7, which preferably consists of a high-insulating material heat, firmly connected, for example by gluing, which is symbolized by three horizontal lines. At its reveal side, the outer insulating body 5 is covered by a fiber cement pad 8, while the inner insulating body 5 is covered on its reveal side by a plastic shell 9, which is drawn around the edge on the inside of the wall to form a mechanical edge protection.

Wie die Zeichnung zeigt, ist an dem äußeren Isolierkörper 5 ein Falz 10 ausgebildet, in den der Brückenkörper 7 eingesetzt ist und von dem äußeren Isolierkörper 5 teilweise überdeckt wird. Der äußere Isolierkörper 5 ist auf seiner der Laibung abgewandten Seite, d.h. in Richtung auf die Wärmeisolierplatte 3, über den Brückenkörper 7 hinaus verlängert und in diesem Bereich durch Verlängerung der Grundfläche des Falzes 10 gegenüber der Grenzfläche zwischen der Außenwandschale 1 und der Wärmeisolierplatte 3 zurückgesetzt, so dass sich zwischen dem Brückenkörper 7, dem äußeren Isolierkörper 5 und der Außenwandschale 1 ein Falz 11 ausbildet, in den ein elastischer Dichtungsschaumstoffstreifen 12 eingelegt ist, der an den ihn umgebenden Flächen elastisch anliegt.As the drawing shows, a fold 10 is formed on the outer insulating body 5, in which the bridge body 7 is inserted and is partially covered by the outer insulating body 5. The outer insulating body 5 is on its side facing away from the soffit, i. in the direction of the heat insulating 3, extended beyond the bridge body 7 out and reset in this area by extending the base of the fold 10 with respect to the interface between the outer wall shell 1 and the heat insulating 3, so that between the bridge body 7, the outer insulator 5 and the outer wall shell 1 forms a fold 11 into which an elastic sealing foam strip 12 is inserted, which bears elastically against the surfaces surrounding it.

Zwischen die Stirnseite der Wärmeisolierplatte 3 und dem Brückenkörper 7 ist ein Dichtungsschaumstoffband 13 eingefügt, das einen Luftspalt ausfüllt, der aus Gründen der Sicherheit gegen Beschädigung der Wärmeisolierplatte 3 bei der Montage vorgesehen ist. Dieser Schaumstoffstreifen 13 verhindert somit Luftzirkulationen, die die Wärmedämmung beeinträchtigen könnten.Between the front side of the heat insulating 3 and the bridge body 7, a sealing foam tape 13 is inserted, which fills an air gap, which is provided for reasons of safety against damage to the heat insulating 3 during assembly. This foam strip 13 thus prevents air circulation, which could affect the thermal insulation.

Die Wärmeisolierplatte 3, der Brückenkörper 7 und der innere Isolierkörper 6 sind auf der dem Beton zugewandten Seite mittels eines Butylbandes 14 miteinander verbunden, das eine Feuchtigkeitsdichtung darstellt.The heat insulating plate 3, the bridge body 7 and the inner insulating body 6 are connected to each other on the concrete side by means of a Butylbandes 14, which constitutes a moisture seal.

Wie man erkennt, sind die beiden Wärmeisolierkörper 5 und 6 mit den Wandschalen 1 und 2, 4 fest und formschlüssig vergossen.As can be seen, the two heat insulating 5 and 6 with the wall shells 1 and 2, 4 shed firmly and positively.

Ein Wandelement der hier beschriebenen Art wird auf folgende Weise hergestellt:A wall element of the type described here is produced in the following way:

Auf einer glatten Unterlageplatte, die einen hochstehenden, dem Umriss des zu erstellenden Wandelements bestimmenden Rand aufweist, wird die komplette, die Wandöffnung bestimmende Zarge Z an vorgegebener Stelle angeordnet. Dabei kann die Zarge Z von einem hier nicht dargestellten Blindkörper (Dummy) ausgefüllt sein; der die Holme der Zarge gegen ein Durchbiegen infolge des auf sie einwirkenden Drucks des zu gießenden Betons schützt. Das Schaumstoffdichtungsband 12 ist an der Zarge vorzugsweise bereits angebracht oder wird anschließend angebracht. Sodann wird die äußere Wandschale 1 durch Eingießen von Beton in die so vorbereitete Form hergestellt. Vorzugsweise zuvor ist auch das Dichtungsschaumband 13 bereits an dem Brückenkörper 7 angebracht worden, und die Wärmeisolierplatte 3 wird anschließend in den Frischbeton eingelegt oder nach dem Aushärten des Betons an der Innenseite der Wandschale 1 angeklebt. Die Wärmeisolierplatte 3 ist von Abstandshaltern durchdrungen (nicht dargestellt), die an der Außenwandschale 1 befestigt sind, beispielsweise an vorgegebenen Stellen in sie eingebettet sind, und eine Länge haben, die bis in die Ebene reicht, in der der freie Rand der den inneren Isolierkörper 6 überdeckenden Kunststoffschale 9 liegt. Diese Abstandshalter dienen der Abstützung der äußeren Wandschale 1 im gestürzten Zustand derselben. Sie sollten vorzugsweise aus einem wärmeisolierenden Material bestehen, da sie später unvermeidliche Brücken zwischen den äußeren und inneren Wandschalen bilden. In der Praxis haben sich hierfür Glasfiberstäbe bewährt, da sie bei vergleichsweise geringer Dicke eine hohe Druck- und Biegefestigkeit haben.On a smooth base plate, which has an upstanding, the outline of the wall element to be created determining edge, the complete, the wall opening determining frame Z is arranged at a predetermined location. In this case, the frame Z can be filled by a dummy body (dummy), not shown here; protects the spars of the frame against bending as a result of the pressure acting on them to be cast concrete. The foam sealing tape 12 is preferably already attached to the frame or is subsequently attached. Then, the outer wall shell 1 by pouring concrete in the thus prepared Mold made. Preferably, the sealing foam tape 13 has already been attached to the bridge body 7, and the heat insulating plate 3 is then inserted into the fresh concrete or adhered to the inside of the wall shell 1 after curing of the concrete. The heat insulating plate 3 is penetrated by spacers (not shown) which are fixed to the outer wall shell 1, for example, embedded in predetermined locations in it, and have a length which extends into the plane in which the free edge of the inner insulating body 6 covering plastic shell 9 is located. These spacers serve to support the outer wall shell 1 in the fallen state of the same. They should preferably be made of a thermally insulating material, since they later form inevitable bridges between the outer and inner wall shells. In practice, this glass fiber rods have proven to be because they have a high compressive and flexural strength at a comparatively small thickness.

Nach dem Aushärten des Betons der Außenwandschale 1 wird die so vorbereitete Anordnung gestürzt und auf eine glatte Unterlageplatte aufgesetzt, die einen hochgezogenen Rand hat, der wieder den Umriss des herzustellenden Wandelements bestimmt. Sodann wird auf dieser Unterlageplatte die Innenwandschale 2 bis zu einer Höhe gegossen, die durch die in der Zeichnung dargestellte Trennlinie T definiert und für die Gewährleistung einer für den Transport notwendigen Festigkeit der Innenwandschale 2 ausreichend ist. Es verbleibt dadurch ein freier Hohlraum zwischen der Innenwandschale 2 und der Wärmeisolierplatte 3. Dieser Hohlraum vermindert das Gewicht des fertigen Wandelements in einem Ausmaß, dass es für den Transport von der Fabrik zur und die Handhabung auf der Baustelle geeignet ist.After curing of the concrete of the outer wall shell 1, the arrangement thus prepared is overthrown and placed on a smooth base plate, which has a raised edge, which again determines the outline of the wall element to be produced. Then, the inner wall shell 2 is poured on this base plate to a height which is defined by the dividing line T shown in the drawing and sufficient to ensure a necessary for the transport strength of the inner wall shell 2. This leaves a free cavity between the inner wall shell 2 and the heat insulating plate 3. This cavity reduces the weight of the finished wall element to such an extent that it is suitable for transportation from the factory to and on-site handling.

Auf der Baustelle wird der Hohlraum des so angelieferten Wandelements nach seinem Einbau am vorgegebenen Platz mit Beton ausgegossen, um die Betonfüllung 4 zwischen der Innenwandschale 2 und der Wärmeisolierplatte 3 zu bilden, die dadurch Teil der Innenwandschale wird.At the construction site, the cavity of the wall element thus supplied is poured out after its installation at the predetermined place with concrete to form the concrete filling 4 between the inner wall shell 2 and the heat insulating 3, which thereby becomes part of the inner wall shell.

Man erkennt, dass durch geeignete Oberflächenstrukturierung der inneren und äußeren Isolierkörper 5 und 6 ein inniger mechanischer Formverbund zwischen den Isolierkörpern 5 und 6 und dem Beton hergestellt werden kann. Während des gesamten Betongießvorgangs stabilisiert der Blindkörper die Zarge gegen den Druck des Betons. Der Blindkörper kann ferner bei der Überprüfung der Wärmedurchgangszahl verwendet werden.It can be seen that, by suitable surface structuring of the inner and outer insulating bodies 5 and 6, an intimate mechanical molding bond can be produced between the insulating bodies 5 and 6 and the concrete. Throughout the concrete casting process, the dummy body stabilizes the frame against the pressure of the concrete. The dummy body can also be used in the heat transfer coefficient check.

Es versteht sich, dass die. Erfindung auch an Wandelementen einsetzbar ist, die nicht aus Beton bestehen, sondern beispielsweise gemauert oder in Holzbauweise erstellt sind.It is understood that the. Invention can also be used on wall elements that are not made of concrete, but for example, masonry or created in wood construction.

Der Blendrahmen des in der Wandöffnung anzubringenden Fensters oder der Tür kann nach Entfernung des Blindkörpers an dem Brückenkörper angebracht werden, wobei insbesondere bei der Verwendung von Schrauben darauf geachtet werden muss, dass diese ausreichend kurz sind, um auszuschließen, dass sie in die Wärmeisolierplatte eindringen können.The frame of the window or door to be mounted in the wall opening may be attached to the bridge body after removal of the blind body, and care must be taken, especially when using screws, that they are sufficiently short to preclude their being able to penetrate the thermal insulation panel ,
