Definitions
- the invention relates to a device for closing a lying in a façade level of a building expansion joint between an outer facade layer and a preferably flush with respect to the façade level built door or window element with the features of the preamble of claim 1. Furthermore, the invention relates to a method for closing a lying in a façade level of a building expansion joint using such a device.
- connection is able to absorb movements of the door or window element in relation to the connected facade layer, so that cracking does not occur.
- Such movements of the door or facade element are due in particular to thermally induced changes in length. Therefore, such a connection is regularly formed as an expansion joint.
- joints boundary surfaces which are formed on the one hand by the door or window element and on the other hand by the outer facade layer or this limiting profile, filled with an elastic sealant.
- a disadvantage here proves that the sealing material remains visible and therefore the expansion joint is visually less appealing.
- connection of the outer facade layer takes place laterally on a frame profile of the door or window element.
- the connecting joint thus comes to an exposed point and is thus clearly visible.
- the stress on the joint increases. The stress increases even more when the joint between an outer facade layer and a built-in with respect to the façade level above door or window element is formed, as collects on the projecting frame profiles surface water, which then presses against the joint.
- the object of the present invention is to provide a device for closing a lying in a facade level of a building expansion joint between an outer facade layer and a preferably flush mounted with respect to the façade level door or window element, on the one hand a permanent as possible tight connection and on the other hand an optical appealing solution for this constructive detail allows. Furthermore, the device should be easy to use, in order to increase the reliability of execution.
- a device for closing a lying in a façade level of a building expansion joint with the features of claim 1 is proposed.
- Advantageous developments of this device are specified in the subclaims.
- the device proposed for closing an expansion joint lying in a façade plane of a building comprises a flexurally elastic sealing strip which has a terminal strip for connection to the facade layer on a first side edge and a clamping body for connection to the door or window element on a second side edge.
- the clamping body allows a positive and / or positive connection of the device with the door or window element, for example, by the clamping body is inserted into a laterally formed on a profile of the door or window member groove and clamped with the groove walls. That is to say that the clamping body preferably has a cross-section matched to such a groove, in particular has an at least slight oversize relative to the groove cross-section in order to achieve the desired clamping action achieve.
- An excess of the clamping body relative to the groove cross-section has the consequence that the clamping body bears against at least two, preferably parallel side walls of the groove under prestress.
- Such a clamping connection can be produced in a simple manner by inserting or pressing the clamping body into the groove, so that the connection of the device to the door or window element is significantly simplified. Furthermore, a tight connection to the door or window element is ensured, since the prestressed against the Nutbegrenzungsdorfn clamping body ensures the required tightness.
- an adhesive or a sealant can be introduced into the groove prior to insertion of the clamp body, which or which ensures a watertight connection after insertion of the clamp body.
- the groove for receiving the clamp body usually does not have to be manufactured first, since industrially manufactured door or window elements with plastic or metal profiles are usually already equipped with such grooves in the region of a stop surface. If the prefabricated grooves differ in the door or window elements of different manufacturers, the sprag cross sections can be adapted to this. In this case, devices according to the invention can be provided with different clamping body cross sections, so that the device can be used in many ways.
- the arranged on a side edge of the sealing strip clamping body may be integrally connected to the bending elastic sealing strip or formed by the sealing tape itself by this has a shaped as a clamping body end. Since the clamping body must have a certain elasticity for the preparation of the clamping connection, the execution of the clamping body of the same material as the sealing tape offers.
- the provided on the other side edge of the sealing strip terminal block for connecting the device to the facade layer has over the flexurally elastic sealing band and the clamping body to a certain dimensional stability in order to support the device on an outer facade layer or a facade layer receiving component.
- a substantially dimensionally rigid connection strip can serve to form a boundary wall of the expansion joint. This is especially true when the outer facade layer is a plaster view, which receives a stable, in particular impact-insensitive end edge by a correspondingly formed terminal block.
- connection of the terminal block with the outer facade layer or the facade layer receiving device is preferably carried out by means of gluing and / or by means of mechanical fasteners. That is, the terminal block as well as the terminal body is installed fixed in position, wherein the terminal strip connecting with the clamping body bending elastic sealing tape is able to compensate for any movements of the clamping body relative to the terminal block.
- the movements of the clamping body can be due in particular to thermally induced changes in position of the door or window element.
- the sealing strip is preferably connected to the terminal block and the clamping body in such a way that after installation of the same, the bending elastic sealing strip forms a loop, that is bent substantially U-shaped.
- the loop shape of the sealing strip allows movement of the clamping body on the terminal block to and from the terminal block away.
- a relative displacement of the clamp body relative to the terminal block in a direction perpendicular or obliquely to the facade level is possible. The same applies, moreover, in the event that the terminal block moves relative to the clamping body.
- movements can be compensated for both within the façade plane and transversely thereto via the U-shaped curved sealing strip.
- the loop shape also allows combinations of longitudinal and transverse movements.
- the loop shape can be arranged such that an open expansion joint, i. a shadow joint is formed, so that a visually appealing solution for this constructive detail is offered. If the formation of a closed joint is desired, the cavity of the shadow gap can be subsequently filled with a sealing material or a sealing compound. However, filling the cavity is not absolutely necessary with regard to the tightness of the connection.
- the sealing strip and / or the terminal block made of plastic, wherein preferably the sealing tape is integrally connected by gluing, vulcanization or overmolding with the terminal block.
- Plastic has the advantage that it is insensitive to moisture and therefore particularly suitable for outdoor use. Furthermore, plastic - compared to metal - a comparatively poor heat conductor, so that the terminal block has a high dimensional stability even with significant temperature fluctuations. Finally, the use of plastic as a material allows a simple and inexpensive production of the device.
- the terminal block is formed substantially angularly and has at least one leg for engagement with a component.
- the component preferably serves to receive the facade layer, in particular a single-layer or multi-layer plaster layer, to which it is necessary to connect the device.
- the component may in particular be a thermal insulation board or a plaster base plate. If the facade layer to be connected comprises plate-shaped clothing elements, the component for receiving the connection strip can also be a profile of a substructure for fastening the clothing element. Alternatively, it is also possible to attach the terminal block directly to the clothing element.
- the terminal block comprises two legs aligned at right angles to one another, wherein a first leg receives the sealing band and a second leg receives a reinforcing mesh or lattice.
- the reinforcing fabric or grid connected to the second leg serves to connect the device to a reinforcing layer of a preferably multi-layered plaster layer.
- the reinforcement fabric or mesh connected to the connection strip is arranged overlapping with a reinforcement fabric or mesh to be embedded in the plaster layer. This ensures that the terminal block does not break off from the outer facade layer.
- the two legs which are at right angles to one another, form an edge protection for the component to which they are attached.
- the terminal block preferably in extension of a leg on a plastering edge, whose length further preferably corresponds to the layer thickness of the applied facade layer, in particular plaster view.
- the plastering edge of the terminal strip can therefore serve the layer thickness adjustment of the plaster layer by the plaster layer is removed manually with a trowel or trowel over the plastering edge.
- the plastering edge of the terminal block forms a clean finish of the plaster layer, which is also insensitive to mechanical stresses.
- the brushing edge may at least partially have a straight, oblique or curved course and / or be cranked in the direction of the opening of the expansion joint. By means of such a bend, for example, a sealing strip placed on the connection strip can be covered.
- the clamping body for non-positive and / or positive connection with a profile of the door or window element is at least partially elastically deformable.
- the clamping body can also be designed as a hollow body.
- the clamping body may have internal air-filled chambers, which contribute to the deformability of the clamping body. As a result, the insertion of the clamping body is simplified in a groove of a profile of the door or window element.
- the clamping body has a substantially rectangular cross-section, which preferably has a certain excess over a rectangular in cross-section groove of the profile of the door or window element. After insertion of the clamp body in the groove this is then applied via two parallel side edges under bias to the groove walls. In this way, an at least positive connection can be realized. Furthermore, in order to enable positive locking, it can further be provided that in each case at least one elastically deformable clamping nose is formed on two parallel side edges of the substantially rectangular clamping body.
- the clamping lugs can cooperate with undercuts of the groove in such a way that a positive connection is effected.
- the groove may be formed to form an undercut, for example C-shaped. Undercuts can also be formed by longitudinal grooves in the groove side walls. Instead of individual grooves, the groove may also have a corrugation and the clamping body corresponding thereto formed clamping lugs or longitudinal clamping webs.
- the sealing strip in the cross-section is preferably bent in a U-shape, wherein furthermore preferably the opening for forming a shadow gap faces outward.
- the shadow gap or the opening can also be filled with a sealant.
- the Sealing compound should be sufficiently elastically deformable to continue to accommodate movements of the door or window element can.
- the opening is not filled, since the shadow gap is a visually appealing constructive detail.
- At least the flexurally elastic sealing strip is made of a dark, preferably black material, produced or dark, in particular black, dyed.
- a dark, preferably black material produced or dark, in particular black, dyed.
- the device according to the invention can be present in the piece, so that it only has to be cut to length on site at the construction site. If several sections must be placed together, they are preferably glued together in the joint area.
- the bonding of two clamping bodies is preferably carried out via an introduced into the groove adhesive or introduced sealing compound before the clamp body are inserted and pushed.
- the bonding in the joint region of two sealing strips is preferably carried out via a further sealing tape which is glued overlapping on both sealing strips.
- An adhesion in the joint area of two terminal strips for the connection of a facade layer is unnecessary, if it is the facade layer, for example, a plaster layer.
- a challenge is the formation of an expansion joint in the area of an outer corner.
- the device according to the invention can - as described above - be pushed and glued, the further sealing tape for bonding with the sealing strips of the device must be sized large enough to the gap between the Sealing tapes in the area of the outer corner.
- the connection strip must be supplemented.
- the device according to the invention can be formed as an outer corner by clamping body, sealing tape and terminal block form an angle. The connection of the outer corner is then again in the manner described above (bumping and gluing).
- the method further proposed for closing an expansion joint lying in a façade plane of a building provides for the use of a device according to the invention.
- the terminal body is connected to a profile of the door or window element and the terminal block with a component for receiving the facade layer, in particular plaster layer, wherein the bending elastic sealing strip is bent in a U-shape.
- the U-shaped bending of the sealing tape causes the formation of a loop, via which the device according to the invention is able to absorb movements that are carried out both within the facade level and across the façade level through the connected facade layer and / or the connected door or window element become.
- the U-shaped bending of the sealing strip or the loop shape produced in this way is decisive for the visual impression of the constructive details formed in this way, since this leads to the formation of a shadow gap.
- the U-shaped bending of the sealing tape is essential Process step.
- the sealing strip can be pre-bent, moreover, already U-shaped.
- either the clamping body can be inserted into a groove of a profile of a door or window element or the terminal block can be connected to a component for receiving the outer facade layer, in particular plaster layer.
- the order in which the connection of the device according to the invention to the adjacent components takes place is basically irrelevant.
- the door or window element is initially installed and then the clamping body of the device according to the invention is pressed into a groove of a profile of the door or window element.
- the terminal block is then applied to a profile of the door or window element opposite side surface of a building or facade element, so that the preferably rectangular formed terminal strip surrounds the outer edge of the building or facade element.
- the building or façade element of the recording of a plaster layer is used, wherein the terminal block connected to the building or facade element is at least partially plastered. If a reinforcing fabric or mesh is applied to the leg lying parallel to the façade plane, this is also plastered. Furthermore, for setting the layer thickness of the plaster layer, a plastering edge can be formed on the connection strip, in that the plastering edge serves to attach the trowel or trowel when the plaster is pulled off or smoothed.
- FIG. 1 shows the typical scope of a device according to the invention, because the device is used to connect an outer facade layer 2 to a door or window element 3 to form an expansion joint 1.
- the door or window element 3 is substantially flush with the facade plane E, ie laying-free built-in.

- An Indian Armtechniks slaughter embedded reinforcing fabric 9 is thereby introduced overlapping, so that a good bond of the terminal block 5 is given to the facade layer 2 and the multilayer plaster layer.
- the terminal strip 5 furthermore has a plastering edge 10, which in the present case serves to adjust the layer thickness of the reinforcing layer having the reinforcing fabric 9.
- the plastering edge 10 is then covered by an applied on the reinforcing layer finishing layer, so that the plastering edge 10 does not appear visually. If the plastering edge 10 is also to serve the layer thickness adjustment of the topcoat layer, it can be made longer, so that it is flush with the topcoat layer.
- the sealing strip 4 has a clamping body 6.
- the clamping body 6 has a substantially rectangular cross section with two parallel side edges 6.1 and 6.2, on each of which a clamping lug 12 is formed (see FIG. 2 ).

In this way, not only a force, but also a positive connection of the clamping body 6 is effected with the profile 11 of the door or window element.
- the clamping connection also causes a seal of the terminal.
- the seal is also made on the expansion joint 1 away by the flexurally elastic sealing band 4. In the area of the connection of the device to the outer facade layer 2, the seal is ensured by the fact that the terminal block 5 is plastered.
- the sealing function of the device is maintained even if the terminal block 5 and / or the clamping body 6 within the Facade level E and / or moved transversely thereto. Because the movements only cause a change in shape of the U-shaped curved sealing strip 4, which makes such a change in shape without further notice.
- the FIG. 2 alone is a device according to the invention with a U-shaped curved sealing strip 4 according to the installation situation in the FIG. 1 refer to.
- the terminal strip 5 has a first leg 7.1 and a second leg 7.2, wherein the first leg 7.1 connected to the sealing strip 4 and the second leg 7.2 with a reinforcing fabric 9 is.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge zwischen einer außenliegenden Fassadenschicht und einem vorzugsweise bündig in Bezug auf die Fassadenebene eingebauten Tür- oder Fensterelement mit den Merkmalen des Oberbegriffs des Anspruchs 1. Ferner betrifft die Erfindung ein Verfahren zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge unter Verwendung einer solchen Vorrichtung.The invention relates to a device for closing a lying in a façade level of a building expansion joint between an outer facade layer and a preferably flush with respect to the façade level built door or window element with the features of the preamble of claim 1. Furthermore, the invention relates to a method for closing a lying in a façade level of a building expansion joint using such a device.
Der gestalterisch oftmals erwünschte flächenbündige Einbau von Fenster- und Türelementen in Gebäudefassaden stellt Planer und Bauausführende regelmäßig vor eine Herausforderung. Denn die den Fassadenabschluss bildende außenliegende Schicht, beispielsweise eine Putzschicht, muss an das Tür- oder Fensterelement dauerhaft dicht angeschlossen werden. Zugleich soll der Anschluss ästhetischen Ansprüchen genügen.The flush design of window and door elements in building facades, which is often desirable from the design point of view, regularly presents planners and building contractors with a challenge. For the outer layer forming the façade finish, for example a plaster layer, must be permanently sealed to the door or window element. At the same time, the connection should meet aesthetic demands.
Die Ausbildung eines dauerhaft dichten Anschlusses setzt voraus, dass der Anschluss in der Lage ist, Bewegungen des Tür- oder Fensterelementes gegenüber der angeschlossenen Fassadenschicht aufzunehmen, damit es nicht zur Rissbildung kommt. Derartige Bewegungen des Tür- oder Fassadenelementes sind insbesondere auf thermisch bedingte Längenänderungen zurückzuführen. Daher wird ein solcher Anschluss regelmäßig als Dehnungsfuge ausgebildet. Hierzu werden zwischen den Fugen Begrenzungsflächen, welche einerseits durch das Tür- oder Fensterelement und andererseits durch die außenliegende Fassadenschicht oder ein dieses begrenzendes Profil gebildet werden, mit einer elastischen Dichtmasse verfüllt. Als ein Nachteil erweist sich hierbei, dass das Dichtmaterial sichtbar bleibt und demzufolge die Dehnungsfuge optisch wenig ansprechend ist.The formation of a permanently sealed connection presupposes that the connection is able to absorb movements of the door or window element in relation to the connected facade layer, so that cracking does not occur. Such movements of the door or facade element are due in particular to thermally induced changes in length. Therefore, such a connection is regularly formed as an expansion joint. For this purpose, between the joints boundary surfaces, which are formed on the one hand by the door or window element and on the other hand by the outer facade layer or this limiting profile, filled with an elastic sealant. A disadvantage here proves that the sealing material remains visible and therefore the expansion joint is visually less appealing.
Darüber hinaus ist eine Vielzahl konstruktiv aufwendiger Einzellösungen zur Ausbildung einer Dehnungsfuge zwischen einem flächenbündig eingebauten Tür- oder Fensterelement und einer außenliegenden Fassadenschicht bekannt, welche zwar ästhetischen Ansprüchen genügen, jedoch eine sorgfältige Ausführung erfordern, damit ferner gewährleistet ist, dass der Anschluss dauerhaft dicht ist. In den meisten Fällen ist eine optisch ansprechende Dehnungsfuge als Schattenfuge ausgebildet. D.h., dass das fugenschließende Material zurückliegend angeordnet ist, wobei ein Hohlraum - die sogenannte Schattenfuge - verbleibt. Ferner sind Lösungen bekannt, bei welchen die Schattenfuge in der Tiefe und in der Breite über ein Winkelprofil begrenzt wird, wobei das Winkelprofil hinter das anzuschließende Fassadenelement geführt und der verbleibende Zwischenraum mit einem Dichtelement bzw. einer Dichtmasse geschlossen wird.In addition, a variety of structurally complex individual solutions for forming an expansion joint between a flush mounted door or window element and an outer facade layer is known, which indeed satisfy aesthetic requirements, but require careful execution, so that it is also ensured that the connection is permanently sealed. In most cases, a visually appealing expansion joint is designed as a shadow gap. That is, the joint-closing material is disposed backward, leaving a cavity, the so-called shadow gap. Furthermore, solutions are known in which the shadow gap is limited in depth and in width via an angle profile, wherein the angle profile is guided behind the facade element to be connected and the remaining space is closed with a sealing element or a sealing compound.
Die Problematik bei allen Lösungen besteht in der Regel jedoch darin, dass - eine sorgfältige Ausführung vorausgesetzt - die Dichtigkeit auf Dauer dennoch nicht gewährleistet werden kann. Dehnungsfugen sind zu warten und bei Mängeln zu erneuern. Denn Mängel, wie beispielsweise Risse im Bereich der Dehnungsfuge, können zum Eindringen von Feuchtigkeit und damit zu Schäden an dem Gebäude führen.However, the problem with all solutions is usually that - assuming a careful execution - the tightness can not be guaranteed in the long term. Expansion joints are to be maintained and renewed in case of defects. Because defects, such as cracks in the area of the expansion joint, can lead to the ingress of moisture and thus damage to the building.
Beim laibungsfreien, d.h. flächenbündigen oder vorstehenden Einbau eines Tür- oder Fassadenelementes erfolgt der Anschluss der außenliegenden Fassadenschicht seitlich an einem Rahmenprofil des Tür- oder Fensterelementes. Das heißt, dass die Fuge innerhalb der Fassadenebene ausgebildet wird. Die Anschlussfuge kommt somit an exponierter Stelle zu liegen und ist somit deutlich sichtbar. Ferner steigt aufgrund direkter Bewitterung die Beanspruchung der Fuge. Die Beanspruchung nimmt sogar noch zu, wenn die Fuge zwischen einer außenliegenden Fassadenschicht und einem in Bezug auf die Fassadenebene vorstehend eingebauten Tür- oder Fensterelement ausgebildet wird, da sich auf den vorstehenden Rahmenprofilen Oberflächenwasser sammelt, das dann gegen die Fuge drückt.When laying-off, ie flush or protruding installation of a door or facade element, the connection of the outer facade layer takes place laterally on a frame profile of the door or window element. This means that the joint is formed within the façade level. The connecting joint thus comes to an exposed point and is thus clearly visible. Furthermore, due to direct weathering, the stress on the joint increases. The stress increases even more when the joint between an outer facade layer and a built-in with respect to the façade level above door or window element is formed, as collects on the projecting frame profiles surface water, which then presses against the joint.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge zwischen einer außenliegenden Fassadenschicht und einem vorzugsweise bündig in Bezug auf die Fassadenebene eingebauten Tür- oder Fensterelement anzugeben, welche einerseits einen möglichst dauerhaft dichten Anschluss und andererseits ein optisch ansprechende Lösung für dieses konstruktive Detail ermöglicht. Ferner soll die Vorrichtung einfach einzusetzen sein, um auf diese Weise die Ausführungssicherheit zu erhöhen.The object of the present invention is to provide a device for closing a lying in a facade level of a building expansion joint between an outer facade layer and a preferably flush mounted with respect to the façade level door or window element, on the one hand a permanent as possible tight connection and on the other hand an optical appealing solution for this constructive detail allows. Furthermore, the device should be easy to use, in order to increase the reliability of execution.
Zur Lösung der Aufgabe wird eine Vorrichtung zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge mit den Merkmalen des Anspruchs 1 vorgeschlagen. Vorteilhafte Weiterbildungen dieser Vorrichtung sind in den Unteransprüchen angegeben. Ferner wird ein Verfahren zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge unter Verwendung einer erfindungsgemäßen Vorrichtung beansprucht.To achieve the object, a device for closing a lying in a façade level of a building expansion joint with the features of claim 1 is proposed. Advantageous developments of this device are specified in the subclaims. Furthermore, a method for closing a lying in a façade level of a building expansion joint using a device according to the invention claimed.
Die zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge vorgeschlagene Vorrichtung umfasst ein biegeelastisches Dichtband, dass an einer ersten Seitenkante eine Anschlussleiste für den Anschluss an die Fassadenschicht und an einer zweiten Seitenkante einen Klemmkörper für den Anschluss an das Tür- oder Fensterelement aufweist. Der Klemmkörper ermöglicht eine kraft- und/oder formschlüssige Verbindung der Vorrichtung mit dem Tür- oder Fensterelement, indem beispielsweise der Klemmkörper in eine seitlich an einem Profil des Tür- oder Fensterelement ausgebildeten Nut eingesetzt und mit den Nutwänden verklemmt wird. D.h., dass der Klemmkörper vorzugsweise einen auf eine solche Nut abgestimmten Querschnitt besitzt, insbesondere ein zumindest geringfügiges Übermaß gegenüber dem Nutquerschnitt besitzt, um die erwünschte Klemmwirkung zu erzielen. Ein Übermaß des Klemmkörpers gegenüber dem Nutquerschnitt hat zur Folge, dass der Klemmkörper an wenigstens zwei, vorzugsweise parallelen Seitenwänden der Nut unter Vorspannung anliegt. Eine solche Klemmverbindung ist in einfacher Weise durch Einsetzen bzw. Eindrücken des Klemmkörpers in die Nut herstellbar, so dass der Anschluss der Vorrichtung an das Tür- oder Fensterelement deutlich vereinfacht wird. Ferner ist ein dichter Anschluss an das Tür- oder Fensterelement sichergestellt, da der unter Vorspannung an den Nutbegrenzungswänden anliegende Klemmkörper die erforderliche Dichtigkeit gewährleistet. Ergänzend kann in die Nut vor dem Einsetzen des Klemmkörpers ein Kleber oder eine Dichtmasse eingebracht werden, welcher bzw. welche nach dem Einsetzen des Klemmkörpers einen wasserdichten Anschluss gewährleistet.The device proposed for closing an expansion joint lying in a façade plane of a building comprises a flexurally elastic sealing strip which has a terminal strip for connection to the facade layer on a first side edge and a clamping body for connection to the door or window element on a second side edge. The clamping body allows a positive and / or positive connection of the device with the door or window element, for example, by the clamping body is inserted into a laterally formed on a profile of the door or window member groove and clamped with the groove walls. That is to say that the clamping body preferably has a cross-section matched to such a groove, in particular has an at least slight oversize relative to the groove cross-section in order to achieve the desired clamping action achieve. An excess of the clamping body relative to the groove cross-section has the consequence that the clamping body bears against at least two, preferably parallel side walls of the groove under prestress. Such a clamping connection can be produced in a simple manner by inserting or pressing the clamping body into the groove, so that the connection of the device to the door or window element is significantly simplified. Furthermore, a tight connection to the door or window element is ensured, since the prestressed against the Nutbegrenzungswänden clamping body ensures the required tightness. In addition, an adhesive or a sealant can be introduced into the groove prior to insertion of the clamp body, which or which ensures a watertight connection after insertion of the clamp body.
Die Nut zur Aufnahme des Klemmkörpers muss in der Regel nicht erst hergestellt werden, da industriell gefertigte Tür- oder Fensterelemente mit Kunststoff- oder Metallprofilen in der Regel bereits mit derartigen Nuten im Bereich einer Anschlagfläche ausgestattet sind. Sofern sich die vorgefertigten Nuten bei den Tür- oder Fensterelementen verschiedener Hersteller unterscheiden, können die Klemmkörperquerschnitte hierauf abgestimmt werden. In diesem Fall können erfindungsgemäße Vorrichtungen mit unterschiedlichen Klemmkörperquerschnitten vorgehalten werden, so dass die Vorrichtung vielseitig einsetzbar ist.The groove for receiving the clamp body usually does not have to be manufactured first, since industrially manufactured door or window elements with plastic or metal profiles are usually already equipped with such grooves in the region of a stop surface. If the prefabricated grooves differ in the door or window elements of different manufacturers, the sprag cross sections can be adapted to this. In this case, devices according to the invention can be provided with different clamping body cross sections, so that the device can be used in many ways.
Der an einer Seitenkante des Dichtbandes angeordnete Klemmkörper kann mit dem biegeelastischen Dichtband einstückig verbunden sein oder durch das Dichtband selbst ausgebildet werden, indem dieses ein als Klemmkörper ausgeformtes Ende besitzt. Da auch der Klemmkörper eine gewisse Elastizität zur Herstellung der Klemmverbindung aufweisen muss, bietet sich die Ausführung des Klemmkörpers aus demselben Werkstoff wie das Dichtband an.The arranged on a side edge of the sealing strip clamping body may be integrally connected to the bending elastic sealing strip or formed by the sealing tape itself by this has a shaped as a clamping body end. Since the clamping body must have a certain elasticity for the preparation of the clamping connection, the execution of the clamping body of the same material as the sealing tape offers.
Die an der weiteren Seitenkante des Dichtbandes vorgesehene Anschlussleiste für den Anschluss der Vorrichtung an die Fassadenschicht weist gegenüber dem biegeelastischen Dichtband und dem Klemmkörper eine gewisse Formsteifigkeit auf, um die Vorrichtung an einer außenliegenden Fassadenschicht bzw. einem die Fassadenschicht aufnehmenden Bauelement abzustützen. Zugleich kann eine im Wesentlichen formsteife Anschlussleiste der Ausbildung einer Begrenzungswand der Dehnungsfuge dienen. Dies gilt insbesondere, wenn die außenliegende Fassadenschicht eine Putzsicht ist, welche durch eine entsprechend ausgebildete Anschlussleiste eine stabile, insbesondere stoßunempfindliche Abschlusskante erhält.The provided on the other side edge of the sealing strip terminal block for connecting the device to the facade layer has over the flexurally elastic sealing band and the clamping body to a certain dimensional stability in order to support the device on an outer facade layer or a facade layer receiving component. At the same time, a substantially dimensionally rigid connection strip can serve to form a boundary wall of the expansion joint. This is especially true when the outer facade layer is a plaster view, which receives a stable, in particular impact-insensitive end edge by a correspondingly formed terminal block.
Die Verbindung der Anschlussleiste mit der außenliegenden Fassadenschicht bzw. dem die Fassadenschicht aufnehmenden Bauelement erfolgt vorzugsweise mittels Kleben und/oder mittels mechanischer Befestigungselemente. D.h., dass die Anschlussleiste ebenso wie der Klemmkörper lagefest eingebaut wird, wobei das die Anschlussleiste mit dem Klemmkörper verbindende biegeelastische Dichtband etwaige Bewegungen des Klemmkörpers gegenüber der Anschlussleiste auszugleichen vermag. Die Bewegungen des Klemmkörpers können dabei insbesondere auf thermisch bedingte Lagenänderungen des Tür- oder Fensterelementes zurückzuführen sein.The connection of the terminal block with the outer facade layer or the facade layer receiving device is preferably carried out by means of gluing and / or by means of mechanical fasteners. That is, the terminal block as well as the terminal body is installed fixed in position, wherein the terminal strip connecting with the clamping body bending elastic sealing tape is able to compensate for any movements of the clamping body relative to the terminal block. The movements of the clamping body can be due in particular to thermally induced changes in position of the door or window element.
Das Dichtband ist vorzugsweise derart mit der Anschlussleiste und dem Klemmkörper verbunden, dass nach Einbau derselben das biegeelastische Dichtband eine Schlaufe bildet, d.h. im Wesentlichen U-förmig gebogen ist. Die Schlaufenform des Dichtbandes ermöglicht eine Bewegung des Klemmkörpers auf die Anschlussleiste zu sowie von der Anschlussleiste weg. Darüber hinaus ist eine Relativverschiebung des Klemmkörpers gegenüber der Anschlussleiste in einer Richtung senkrecht oder schräg zur Fassadenebene möglich. Gleiches gilt im Übrigen für den Fall, dass die Anschlussleiste sich relativ zum Klemmkörper bewegt.The sealing strip is preferably connected to the terminal block and the clamping body in such a way that after installation of the same, the bending elastic sealing strip forms a loop, that is bent substantially U-shaped. The loop shape of the sealing strip allows movement of the clamping body on the terminal block to and from the terminal block away. In addition, a relative displacement of the clamp body relative to the terminal block in a direction perpendicular or obliquely to the facade level is possible. The same applies, moreover, in the event that the terminal block moves relative to the clamping body.
Über das U-förmig gebogene Dichtband können demnach Bewegungen sowohl innerhalb der Fassadenebene als auch quer hierzu kompensiert werden. Entweder vergrößert bzw. verkleinert sich dabei der Abstand der beiden Schenkel des U-förmig gebogenen Dichtbandes zueinander oder es verkürzt bzw. verlängert sich ein Schenkel. Die Schlaufenform lässt zudem Kombinationen aus Längs- und Querbewegungen zu.Accordingly, movements can be compensated for both within the façade plane and transversely thereto via the U-shaped curved sealing strip. Either the distance between the two legs of the U-shaped curved sealing strip increases or decreases, or a limb shortens or lengthens. The loop shape also allows combinations of longitudinal and transverse movements.
Ferner kann die Schlaufenform derart angeordnet werden, dass eine offene Dehnungsfuge, d.h. eine Schattenfuge ausgebildet wird, so dass eine optisch ansprechende Lösung für dieses konstruktive Detail angeboten wird. Sofern die Ausbildung einer geschlossenen Fuge erwünscht ist, kann der Hohlraum der Schattenfuge nachträglich mit einem Dichtmaterial bzw. einer Dichtmasse verfüllt werden. Ein Verfüllen des Hohlraums ist im Hinblick auf die Dichtheit des Anschlusses jedoch nicht zwingend erforderlich.Furthermore, the loop shape can be arranged such that an open expansion joint, i. a shadow joint is formed, so that a visually appealing solution for this constructive detail is offered. If the formation of a closed joint is desired, the cavity of the shadow gap can be subsequently filled with a sealing material or a sealing compound. However, filling the cavity is not absolutely necessary with regard to the tightness of the connection.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist bzw. sind das Dichtband und/oder die Anschlussleiste aus Kunststoff, wobei vorzugsweise das Dichtband stoffschlüssig mittels Kleben, Aufvulkanisieren oder Umspritzen mit der Anschlussleiste verbunden ist. Kunststoff weist den Vorteil auf, dass dieser feuchtigkeitsunempfindlich und demnach für die Anwendung im Außenbereich besonders geeignet ist. Ferner ist Kunststoff - gegenüber Metall - ein vergleichsweise schlechter Wärmeleiter, so dass die Anschlussleiste eine hohe Formstabilität selbst bei deutlichen Temperaturschwankungen besitzt. Schließlich ermöglicht der Einsatz von Kunststoff als Werkstoff eine einfache und kostengünstige Herstellung der Vorrichtung.According to a preferred embodiment of the invention is or are the sealing strip and / or the terminal block made of plastic, wherein preferably the sealing tape is integrally connected by gluing, vulcanization or overmolding with the terminal block. Plastic has the advantage that it is insensitive to moisture and therefore particularly suitable for outdoor use. Furthermore, plastic - compared to metal - a comparatively poor heat conductor, so that the terminal block has a high dimensional stability even with significant temperature fluctuations. Finally, the use of plastic as a material allows a simple and inexpensive production of the device.
Des Weiteren wird vorgeschlagen, dass die Anschlussleiste im Wesentlichen winkelförmig ausgebildet ist und zumindest einen Schenkel zur Anlage an einem Bauelement besitzt. Das Bauelement dient dabei vorzugsweise der Aufnahme der Fassadenschicht, insbesondere einer ein- oder mehrlagigen Putzschicht, an welche es die Vorrichtung anzuschließen gilt. Das Bauelement kann insbesondere eine Wärmedämmplatte oder eine Putzträgerplatte sein. Sofern die anzuschließende Fassadenschicht plattenförmige Bekleidungselemente umfasst, kann das Bauelement zur Aufnahme der Anschlussleiste auch ein Profil einer Unterkonstruktion zur Befestigung des Bekleidungselementes sein. Alternativ ist es auch möglich, die Anschlussleiste direkt an dem Bekleidungselement zu befestigen.Furthermore, it is proposed that the terminal block is formed substantially angularly and has at least one leg for engagement with a component. The component preferably serves to receive the facade layer, in particular a single-layer or multi-layer plaster layer, to which it is necessary to connect the device. The component may in particular be a thermal insulation board or a plaster base plate. If the facade layer to be connected comprises plate-shaped clothing elements, the component for receiving the connection strip can also be a profile of a substructure for fastening the clothing element. Alternatively, it is also possible to attach the terminal block directly to the clothing element.
Gemäß einer Weiterbildung der Erfindung umfasst die Anschlussleiste zwei rechtwinklig zueinander ausgerichtete Schenkel, wobei eine erster Schenkel das Dichtband und ein zweiter Schenkel ein Armierungsgewebe oder - gitter aufnimmt. Das mit dem zweiten Schenkel verbundene Armierungsgewebe oder -gitter dient dem Anschluss der Vorrichtung an eine Armierungsschicht einer vorzugsweise mehrlagig ausgebildeten Putzschicht. Das mit der Anschlussleiste verbundene Armierungsgewebe oder -gitter wird hierzu überlappend mit einem in der Putzschicht einzubettenden Armierungsgewebe oder -gitter angeordnet. Dadurch ist sichergestellt, dass die Anschlussleiste von der außenliegenden Fassadenschicht nicht abreißt. Zugleich bilden die beiden in einem rechten Winkel zueinander stehenden Schenkel einen Kantenschutz für das Bauelement aus, an welchem sie befestigt sind.According to one embodiment of the invention, the terminal block comprises two legs aligned at right angles to one another, wherein a first leg receives the sealing band and a second leg receives a reinforcing mesh or lattice. The reinforcing fabric or grid connected to the second leg serves to connect the device to a reinforcing layer of a preferably multi-layered plaster layer. For this purpose, the reinforcement fabric or mesh connected to the connection strip is arranged overlapping with a reinforcement fabric or mesh to be embedded in the plaster layer. This ensures that the terminal block does not break off from the outer facade layer. At the same time, the two legs, which are at right angles to one another, form an edge protection for the component to which they are attached.
Gemäß einer Weiterbildung der Erfindung weist die Anschlussleiste vorzugsweise in Verlängerung eines Schenkels eine Anputzkante auf, deren Länge weiterhin vorzugsweise der Schichtstärke der aufzutragenden Fassadenschicht, insbesondere Putzsicht entspricht. Die Anputzkante der Anschlussleiste kann demnach der Schichtstärkeneinstellung der Putzschicht dienen, indem die Putzschicht manuell mit einer Traufel oder Kelle über der Anputzkante abgezogen wird. Darüber hinaus bildet die Anputzkante der Anschlussleiste einen sauberen Abschluss der Putzschicht aus, welche zudem unempfindlich gegenüber mechanischen Beanspruchungen ist. Die Anputzkante kann zumindest teilweise einen geraden, schrägen oder bogenförmigen Verlauf aufweisen und/oder in Richtung der Öffnung der Dehnungsfuge gekröpft sein. Mittels einer solchen Kröpfung kann beispielswiese ein auf die Anschlussleiste aufgesetztes Dichtband abgedeckt werden.According to one embodiment of the invention, the terminal block preferably in extension of a leg on a plastering edge, whose length further preferably corresponds to the layer thickness of the applied facade layer, in particular plaster view. The plastering edge of the terminal strip can therefore serve the layer thickness adjustment of the plaster layer by the plaster layer is removed manually with a trowel or trowel over the plastering edge. In addition, the plastering edge of the terminal block forms a clean finish of the plaster layer, which is also insensitive to mechanical stresses. The brushing edge may at least partially have a straight, oblique or curved course and / or be cranked in the direction of the opening of the expansion joint. By means of such a bend, for example, a sealing strip placed on the connection strip can be covered.
Wie bereits vorstehend erwähnt, ist der Klemmkörper zur kraft- und/oder formschlüssigen Verbindung mit einem Profil des Tür- oder Fensterelementes zumindest teilweise elastisch verformbar ausgebildet. Alternativ oder ergänzend kann der Klemmkörper auch als Hohlkörper ausgebildet sein. Beispielsweise kann der Klemmkörper innenliegende luftgefüllte Kammern aufweisen, welche einen Beitrag zur Verformbarkeit des Klemmkörpers leisten. Dadurch wird das Einsetzen des Klemmkörpers in eine Nut eines Profils des Tür- oder Fensterelementes vereinfacht.As already mentioned above, the clamping body for non-positive and / or positive connection with a profile of the door or window element is at least partially elastically deformable. Alternatively or additionally, the clamping body can also be designed as a hollow body. For example, the clamping body may have internal air-filled chambers, which contribute to the deformability of the clamping body. As a result, the insertion of the clamping body is simplified in a groove of a profile of the door or window element.
Gemäß einer bevorzugten Ausführungsform der Erfindung besitzt der Klemmkörper im Wesentlichen einen rechteckigen Querschnitt, welche vorzugsweise ein gewisses Übermaß gegenüber einer im Querschnitt rechteckigen Nut des Profils des Tür- oder Fensterelementes hat. Nach Einsetzen des Klemmkörpers in die Nut liegt dieser dann über zwei parallele Seitenkanten unter Vorspannung an den Nutwänden an. Auf diese Weise kann eine zumindest kraftschlüssige Verbindung realisiert werden. Um darüber hinaus einen Formschluss zu ermöglichen, kann ferner vorgesehen sein, dass an zwei parallelen Seitenkanten des im Wesentlichen rechteckigen Klemmkörpers jeweils wenigstens eine elastisch verformbare Klemmnase ausgebildet ist. Die Klemmnasen können mit Hinterschneidungen der Nut in der Weise zusammenwirken, dass ein Formschluss bewirkt wird. Die Nut kann zur Ausbildung einer Hinterschneidung beispielsweise C-förmig ausgebildet sein. Hinterschneidungen können ferner durch längslaufende Rillen in den Nutseitenwänden ausgebildet werden. Anstelle einzelner Rillen kann die Nut auch eine Riffelung aufweisen und der Klemmkörper korrespondierend hierzu ausgebildete Klemmnasen bzw. längslaufende Klemmstege aufweisen.According to a preferred embodiment of the invention, the clamping body has a substantially rectangular cross-section, which preferably has a certain excess over a rectangular in cross-section groove of the profile of the door or window element. After insertion of the clamp body in the groove this is then applied via two parallel side edges under bias to the groove walls. In this way, an at least positive connection can be realized. Furthermore, in order to enable positive locking, it can further be provided that in each case at least one elastically deformable clamping nose is formed on two parallel side edges of the substantially rectangular clamping body. The clamping lugs can cooperate with undercuts of the groove in such a way that a positive connection is effected. The groove may be formed to form an undercut, for example C-shaped. Undercuts can also be formed by longitudinal grooves in the groove side walls. Instead of individual grooves, the groove may also have a corrugation and the clamping body corresponding thereto formed clamping lugs or longitudinal clamping webs.
Wie vorstehend bereits erwähnt, ist im eingebauten Zustand der erfindungsgemäßen Vorrichtung das Dichtband im Querschnitt vorzugsweise U-förmig gebogen, wobei weiterhin vorzugsweise die Öffnung zur Ausbildung einer Schattenfuge nach außen zeigt. Bei Bedarf kann die Schattenfuge bzw. die Öffnung auch mit einer Dichtmasse verfüllt werden. Die Dichtmasse sollte dabei ausreichend elastisch verformbar sein, um weiterhin Bewegungen des Tür- oder Fensterelementes aufnehmen zu können. Bevorzugt wird die Öffnung jedoch nicht verfüllt, da die Schattenfuge ein optisch ansprechendes konstruktives Detail darstellt.As already mentioned above, in the installed state of the device according to the invention, the sealing strip in the cross-section is preferably bent in a U-shape, wherein furthermore preferably the opening for forming a shadow gap faces outward. If necessary, the shadow gap or the opening can also be filled with a sealant. The Sealing compound should be sufficiently elastically deformable to continue to accommodate movements of the door or window element can. Preferably, however, the opening is not filled, since the shadow gap is a visually appealing constructive detail.
Um den Effekt einer Schattenfuge zu verstärken, kann ferner vorgesehen sein, dass zumindest das biegeelastische Dichtband aus einem dunklen, vorzugsweise schwarzen Werkstoff, hergestellt oder dunkel, insbesondere schwarz, eingefärbt ist. Bei entsprechender Farbgebung des Dichtbandes ist die Tiefe der Fuge nur schwer abschätzbar, so dass der optische Eindruck der Fuge - unabhängig von etwaigen Bewegungen und/oder Formveränderungen des Dichtbandes - gleich bleibend ist.In order to enhance the effect of a shadow gap, it can further be provided that at least the flexurally elastic sealing strip is made of a dark, preferably black material, produced or dark, in particular black, dyed. With appropriate color of the sealing tape, the depth of the joint is difficult to estimate, so that the visual impression of the joint - regardless of any movements and / or changes in shape of the sealing tape - is consistent.
Die erfindungsgemäße Vorrichtung kann als Meterware vorliegen, so dass sie vor Ort auf der Baustelle nur noch auf Länge geschnitten werden muss. Sofern mehrere Teilstücke aneinander gesetzt werden müssen, werden diese im Stoßbereich vorzugsweise miteinander verklebt. Die Verklebung zweier Klemmkörper erfolgt vorzugsweise über einen in die Nut eingebrachten Kleber oder eingebrachte Dichtmasse bevor die Klemmkörper eingesetzt und gestoßen werden. Die Verklebung im Stoßbereich zweier Dichtbänder erfolgt vorzugsweise über ein weiteres Dichtband, das überlappend auf beide Dichtbänder aufgeklebt wird. Eine Verklebung im Stoßbereich zweier Anschlussleisten für den Anschluss einer Fassadenschicht ist entbehrlich, wenn es sich bei der Fassadenschicht beispielsweise um eine Putzschicht handelt.The device according to the invention can be present in the piece, so that it only has to be cut to length on site at the construction site. If several sections must be placed together, they are preferably glued together in the joint area. The bonding of two clamping bodies is preferably carried out via an introduced into the groove adhesive or introduced sealing compound before the clamp body are inserted and pushed. The bonding in the joint region of two sealing strips is preferably carried out via a further sealing tape which is glued overlapping on both sealing strips. An adhesion in the joint area of two terminal strips for the connection of a facade layer is unnecessary, if it is the facade layer, for example, a plaster layer.
Eine Herausforderung stellt die Ausbildung einer Dehnungsfuge im Bereich einer Außenecke dar. Die erfindungsgemäße Vorrichtung kann hierzu - wie zuvor beschrieben - gestoßen und verklebt werden, wobei das weitere Dichtband zur Verklebung mit den Dichtbändern der Vorrichtung ausreichend groß bemessen sein muss, um die Lücke zwischen den Dichtbändern im Bereich der Außenecke zu überbrücken. Ferner muss die Anschlussleiste ergänzt werden. Darüber hinaus kann die erfindungsgemäße Vorrichtung als Außenecke ausgebildet werden, indem Klemmkörper, Dichtband und Anschlussleiste einen Winkel formen. Der Anschluss der Außenecke erfolgt dann wiederum in der zuvor beschriebenen Weise (Stoßen und Verkleben).A challenge is the formation of an expansion joint in the area of an outer corner. The device according to the invention can - as described above - be pushed and glued, the further sealing tape for bonding with the sealing strips of the device must be sized large enough to the gap between the Sealing tapes in the area of the outer corner. Furthermore, the connection strip must be supplemented. In addition, the device according to the invention can be formed as an outer corner by clamping body, sealing tape and terminal block form an angle. The connection of the outer corner is then again in the manner described above (bumping and gluing).
Die Ausbildung einer Innenecke stellt kein Problem dar, da hierzu die Vorrichtung lediglich eingeschnitten und überlappend verlegt werden muss. Das Einschneiden erfolgt von der Seite der Anschlussleiste aus. Die Anschlussleiste wird in diesem Bereich ausgespart.The formation of an inner corner is not a problem, since this requires the device merely cut and overlapping laid. The cutting is done from the side of the terminal block. The terminal block is omitted in this area.
Neben Außenecken können weitere Sonderprofile der Vorrichtung vorgehalten werden, welche beispielsweise die Ausbildung einer Dehnungsfuge im Bereich eines bogenförmig verlaufenden Tür- oder Fensterprofils ermöglichen. Das Dichtband und die Anschlussleiste weisen in diesem Fall einen bogenförmigen Verlauf auf.In addition to outside corners further special profiles of the device can be kept, which allow, for example, the formation of an expansion joint in the region of an arcuate door or window profile. The sealing tape and the terminal block in this case have a curved course.
Das ferner zum Schließen einer in einer Fassadenebene eines Gebäudes liegenden Dehnungsfuge vorgeschlagene Verfahren sieht die Verwendung einer erfindungsgemäßen Vorrichtung vor. Der Klemmkörper wird dabei mit einem Profil des Tür- oder Fensterelementes und die Anschlussleiste mit einem Bauelement zur Aufnahme der Fassadenschicht, insbesondere Putzschicht, verbunden, wobei das biegeelastische Dichtband U-förmig gebogen wird. Das U-förmige Biegen des Dichtbandes bewirkt die Ausbildung einer Schlaufe, über welche die erfindungsgemäße Vorrichtung in der Lage ist, Bewegungen aufzunehmen, die sowohl innerhalb der Fassadenebene als auch quer zur Fassadenebene durch die angeschlossene Fassadenschicht und/oder das angeschlossene Tür- oder Fensterelement ausgeführt werden. Das U-förmige Biegen des Dichtbandes bzw. die auf diese Weise hergestellte Schlaufenform ist bestimmend für den optischen Eindruck des auf diese Weise ausgebildeten konstruktiven Details, da es hierbei zur Ausbildung einer Schattenfuge kommt. Insofern stellt das U-förmige Biegen des Dichtbandes einen Wesentlichen Verfahrensschritt dar. Das Dichtband kann im Übrigen auch bereits U-förmig vorgebogen sein.The method further proposed for closing an expansion joint lying in a façade plane of a building provides for the use of a device according to the invention. The terminal body is connected to a profile of the door or window element and the terminal block with a component for receiving the facade layer, in particular plaster layer, wherein the bending elastic sealing strip is bent in a U-shape. The U-shaped bending of the sealing tape causes the formation of a loop, via which the device according to the invention is able to absorb movements that are carried out both within the facade level and across the façade level through the connected facade layer and / or the connected door or window element become. The U-shaped bending of the sealing strip or the loop shape produced in this way is decisive for the visual impression of the constructive details formed in this way, since this leads to the formation of a shadow gap. In this respect, the U-shaped bending of the sealing tape is essential Process step. The sealing strip can be pre-bent, moreover, already U-shaped.
Zunächst kann entweder der Klemmkörper in eine Nut eines Profils eines Tür- oder Fensterelementes eingesetzt oder die Anschlussleiste mit einem Bauelement zur Aufnahme der außenliegenden Fassadenschicht, insbesondere Putzschicht, verbunden werden. In welcher Reihenfolge der Anschluss der erfindungsgemäßen Vorrichtung an die angrenzenden Bauelemente erfolgt, ist grundsätzlich unerheblich. Gemäß einer bevorzugten Ausführungsform des vorgeschlagenen Verfahrens, wird zunächst das Tür- oder Fensterelement verbaut und danach der Klemmkörper der erfindungsgemäßen Vorrichtung in eine Nut eines Profils des Tür- oder Fensterelementes eingepresst. Die Anschlussleiste wird dann an eine dem Profil des Tür- oder Fensterelementes gegenüberliegende Seitenfläche eines Bau- bzw. Fassadenelementes angelegt, so dass die vorzugsweise rechtwinklig ausgebildete Anschlussleiste die außenliegende Kante des Bau- bzw. Fassadenelementes umgreift. Sofern das Bau- oder Fassadenelement der Aufnahme einer Putzschicht dient, kann nunmehr diese aufgebracht werden, wobei die mit dem Bau- oder Fassadenelement verbundene Anschlussleiste zumindest teilweise eingeputzt wird. Sofern auf dem parallel zur Fassadenebene liegenden Schenkel ein Armierungsgewebe oder -gitter aufgebracht ist, wird dieses ebenfalls eingeputzt. Des Weiteren kann zur Einstellung der Schichtstärke der Putzschicht eine Anputzkante an der Anschlussleiste ausgebildet sein, indem die Anputzkante beim Abziehen oder Glätten des Putzes dem Ansetzen der Traufel oder Kelle dient.First, either the clamping body can be inserted into a groove of a profile of a door or window element or the terminal block can be connected to a component for receiving the outer facade layer, in particular plaster layer. The order in which the connection of the device according to the invention to the adjacent components takes place is basically irrelevant. According to a preferred embodiment of the proposed method, the door or window element is initially installed and then the clamping body of the device according to the invention is pressed into a groove of a profile of the door or window element. The terminal block is then applied to a profile of the door or window element opposite side surface of a building or facade element, so that the preferably rectangular formed terminal strip surrounds the outer edge of the building or facade element. If the building or façade element of the recording of a plaster layer is used, it can now be applied, wherein the terminal block connected to the building or facade element is at least partially plastered. If a reinforcing fabric or mesh is applied to the leg lying parallel to the façade plane, this is also plastered. Furthermore, for setting the layer thickness of the plaster layer, a plastering edge can be formed on the connection strip, in that the plastering edge serves to attach the trowel or trowel when the plaster is pulled off or smoothed.
