Description

Die Erfindung betrifft ein wärmegedämmtes Aussteifungselement für einen Rollladenkasten mit den Merkmalen des Oberbegriffs des Anspruchs 1The invention relates to a thermally insulated stiffening element for a roller shutter box with the features of the preamble of claim 1

Aus der EP 1 705 335 A2 ist ein Rollladenkasten bekannt, der an allen vier Seitenflächen aus Kunststoff-Hohlprofilen gebildet ist. Ein solcher Rollladenkasten ist leicht montierbar. Er ist durch ineinander greifende Profile luftdicht auszubilden und kann mit zusätzlich eingesetzten Wärmedämmelementen gedämmt werden, um Kältebrücken im Bereich des Rollladenkastens zu vermeiden. Weiterhin können durch entsprechende Profilgestaltungen vielfältige Möglichkeiten vorgesehen werden, um Revisionsklappen an der Unterseite oder an der der Gebäudeinnenseite zugewandten Seite auszubilden.From the EP 1 705 335 A2 is a roller shutter box is known, which is formed on all four side surfaces of plastic hollow sections. Such a shutter box is easy to install. It is airtight form by interlocking profiles and can be insulated with additionally used thermal insulation elements to avoid cold spots in the area of the roller shutter box. Furthermore, various options can be provided by appropriate profile designs to form inspection flaps on the underside or on the inside of the building side facing.

Zum Anschluss des Rollladenkastens an die Gebäudedecke sind aus der EP 1 775 415 A2 spezielle Anschlussprofile bekannt, auf die das Deckelprofil des Rollladenkastens aufgerastet werden kann. Das Bodenprofil wird mit dem Blendrahmen des Fensters verbunden, so dass die statische Verbindung zwischen dem oberen Abschnitt des Blendrahmens und der Decke über den Rollladenkasten erfolgt. Bei kurzen Rollladenkästen ist die Steifigkeit der stirnseitig angebrachten Kopfzeile ausreichend, um auf den oberen Bereich des Fensters wirkende Windlasten oder dergleichen vom Blendrahmen in die Decke abzuleiten. Bei größeren Fensterbreiten hingegen müssen zusätzliche Aussteifungselemente, sogenannte Statikkonsolen, montiert werden, um Kräfte vom Blendrahmen in die Decke abzuleiten. Die Besonderheit des Anwendungsfalls besteht darin, dass die Befestigungslinie des Rollladenkastens an der Decke näher an der innenraumseitigen Seitenwand angeordnet ist, und die Befestigungslinie des Bodens am Blendrahmen in einem mittleren Bereich liegt, so dass ein Tiefenversatz entsteht, der überbrückt werden muss. Eine direkte Verbindung der Verbindungsstellen ist zudem nicht möglich, da ja der aufgewickelte Rollladenpanzer umgangen werden muss.To connect the shutter box to the building ceiling are from the EP 1 775 415 A2 special connection profiles known to which the lid profile of the shutter box can be snapped. The floor profile is connected to the frame of the window, so that the static connection between the upper portion of the frame and the ceiling on the roller shutter box takes place. For short roller shutter boxes, the rigidity of the front-mounted head line is sufficient to dissipate acting on the upper region of the window wind loads or the like from the frame in the ceiling. For larger window widths, however, additional stiffening elements, so-called static brackets, must be mounted in order to divert forces from the frame to the ceiling. The special feature of the application is that the attachment line of the roller shutter box the ceiling is arranged closer to the inside side wall, and the attachment line of the bottom of the frame lies in a central region, so that a depth offset is created, which must be bridged. A direct connection of the joints is also not possible, since the wound roller shutter must be bypassed.

Dazu werden bügelförmige Statikkonsolen aus Metall als Aussteifungselemente verwendet, die im Rollladenkasten am unteren Ende mit dem Blendrahmen und am oberen Ende mit dem Deckenelement oder Deckenanschlusselement verschraubt werden.For this purpose, stirrup-shaped structural metal consoles are used as stiffening elements, which are screwed in the shutter box at the bottom with the frame and at the top with the ceiling element or ceiling connection element.

Da üblicherweise an der zur Gebäudeinnenseite gewandten Seite des Rollladenkastens Dämmstoffprofile eingelegt werden, die an ihrer Innenseite der Rundform des aufgewickelten Rollladenpanzers angepasst sind und das gebäudeinnenseitige Luftvolumen im Rollladenkasten möglichst vollständig ausfüllen, müssen die Dämmstoffprofile dort unterbrochen werden, wo ein Aussteifungselement montiert ist. Dort können Wärmebrücken entstehen. Kalte Luft kann durch die Unterbrechung der Dämmelemente an den Aussteifungselemente an die Rückseite der Dämmelemente ziehen. Sowohl der U-Wert und insbesondere der FRSI-Wert (Oberflächentemperatur) werden hierdurch negativ beeinflusst und erreichen ohne besondere Maßnahmen nicht die erforderlichen Mindestwerte.Since usually applied to the building interior side of the roller shutter box insulation profiles are adapted to the inside of the round shape of the wound roller shutter and fill the building inside air volume in the shutter box as completely as possible, the insulation profiles must be interrupted where a stiffening element is mounted. There can be thermal bridges. Cold air can be drawn to the back of the insulation elements by interrupting the insulation elements on the stiffening elements. Both the U value and in particular the FRSI value (surface temperature) are adversely affected by this and do not reach the required minimum values without special measures.

Nach DE 20 2008 000 251 U1 wird vorgeschlagen, Wärmedämmkörper einzusetzen und den Verbindungsbügel des Aussteifungselements als Anschlagfläche zu nutzen. Allerdings ist die Seitenfläche des Verbindungsbügels durch den Wärmedämmkörper nur partiell überdeckt und die vordere und hintere Kante liegen ganz frei, so dass sich über den Verbindungsbügel eine Wärmebrücke bilden kann.To DE 20 2008 000 251 U1 It is proposed to use heat-insulating body and to use the connection bracket of the stiffening element as a stop surface. However, the side surface of the connecting bracket is only partially covered by the heat insulation body and the front and rear edge are completely free, so that can form a thermal bridge over the connecting bracket.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein wärmegedämmtes Aussteifungselement für Rollladenkästen anzugeben, durch das Wärmebrücken vermieden werden und einen leichten Zugriff auf den Rollladenpanzer im Revisionsfall ermöglicht.The object of the present invention is thus to provide a thermally insulated stiffening element for roller shutter boxes, are avoided by the thermal bridges and allows easy access to the roller shutter in case of revision.

Erfindungsgemäß wird diese Aufgabe durch ein wärmegedämmtes Aussteifungselement mit den Merkmalen des Anspruchs 1 gelöst.According to the invention this object is achieved by a thermally insulated stiffening element with the features of claim 1.

Das insbesondere aus Metallblech gebildete eigentliche Aussteifungselement selbst besitzt drei wesentliche Abschnitte:

  • eine Bodenbefestigungslasche, die wenigstens eine Befestigungsbohrung und/oder ein Langloch aufweist;
  • eine Deckenbefestigungslasche, die wenigstens eine Befestigungsbohrung und/oder ein Langloch aufweist;
  • einen ein- oder mehrteiligen Verbindungsbügel, der sich von der Bodenbefestigungslasche bis zur Deckenbefestigungslasche erstreckt und der rechtwinklig zu den genannten Laschen angeordnet ist und der senkrecht zu einer Rollladenkastenlängsachse auszurichten ist.
The actual stiffening element formed in particular from sheet metal itself has three essential sections:
  • a bottom attachment tab having at least one attachment hole and / or a slot;
  • a ceiling mounting bracket having at least one mounting hole and / or a slot;
  • a one- or multi-part connection bracket which extends from the bottom attachment tab to the ceiling mounting bracket and which is arranged at right angles to said tabs and which is to be aligned perpendicular to a roller shutter box longitudinal axis.

Hierdurch ist der eingebaute Verbindungsbügel quer zur Längserstreckung des Rollladenkastens sehr schmal. Es ist nämlich insbesondere dessen Ausdehnung in Längsrichtung des Rollladenkastens auf die Materialstärke des Metallblechs reduziert. Da dies auch die Richtung eines potentiellen Wärmedurchgangs ist, wird die Angriffsfläche für eine Wärmeleitung reduziert. Somit ist es möglich, ein Wärmedämmelement aus einem wärmeisolierenden Dämmstoff an einer weitgehend ebenen Seitenfläche des Verbindungsbügels anzusetzen. Eine seitliche Wärmeabstrahlung wird verhindert.As a result, the built-in connection bracket is very narrow transversely to the longitudinal extension of the roller shutter box. In fact, in particular its extent in the longitudinal direction of the roller shutter box is reduced to the material thickness of the metal sheet. Since this is also the direction of a potential heat transfer, the attack surface is reduced for heat conduction. Thus, it is possible to apply a thermal insulation element made of a heat-insulating material to a substantially flat side surface of the connecting bracket. Lateral heat radiation is prevented.

Dabei ist vorgesehen, dass das Wärmedämmelement mit einem vorspringenden Steg vor der zur Rollladenkastenmitte auszurichtenden Kante des Verbindungsbügels und/oder hinter der zur Gebäudeinnenseite auszurichtenden Kante des Verbindungsbügels liegt. Das heißt, der Verbindungsbügel liegt eingebettet in einer Aussparung des Wärmedämmelements, welche zumindest eine Tiefe entsprechend der Materialstärke des Verbindungsbügels besitzt. Selbst die genannten schmalen Kanten liegen dann nicht mehr frei zur Innenseite des Rollladenkastens oder zu einer der Gebäudeinnenseite zugewandten Seitenfläche des Rollladenkastens.It is provided that the thermal insulation element is located with a projecting web in front of the aligned to the shutter box center edge of the connecting bracket and / or behind the be aligned to the building side edge of the connecting bracket. That is, the connection bracket is embedded in a recess of the heat-insulating element, which has at least one depth corresponding to the material thickness of the connecting bracket. Even the mentioned narrow edges are then no longer exposed to the inside of the roller shutter box or to a side facing the inside of the building of the roller shutter box.

Das Wärmedämmelement besitzt vorzugsweise eine solche Länge - also die Ausdehnung in Längserstreckung des Rollladenkastens gesehen -, dass die Seitenkanten der Boden- und Deckenbefestigungslaschen zumindest gerade vollständig von dem Dämmstoff eingehüllt sind. Eine darüber hinaus gehende Länge des Wärmedämmelements ist ohne weiteres möglich.The heat-insulating element preferably has such a length-that is to say the extent seen in the longitudinal extent of the roller shutter box-that the side edges of the floor and ceiling fastening straps are at least just completely enveloped by the insulating material. An additional length of the thermal insulation element is readily possible.

Weiterhin ist vorgesehen, dass das Wärmedämmelement an seinem oberen und an seinem unteren Ende jeweils Aussparungen besitzt, in welche die Bodenbefestigungslasche und die Deckenbefestigungslasche sowie in welche ggf. über die Bodenbefestigungslasche und die Deckenbefestigungslasche hinausragende Überstände von Befestigungselementen einsetzbar sind. Somit sind dann auch die Laschen soweit es nur irgendwie geht eingebettet und umhüllt, und frei liegende Oberflächenbereiche der insbesondere metallischen Laschen werden insbesondere in Kombination mit einer Abdeckkappe vermieden.It is further provided that the heat-insulating element has at its upper and at its lower end in each case recesses into which the Bodenbefestigungslasche and the ceiling mounting tab and in which optionally over the Bodenbefestigungslasche and the Deckenbefestigungslasche protruding projections of fasteners are used. Thus, then the tabs are as far as it is somehow embedded and enveloped, and exposed surface areas of the particular metallic tabs are avoided in particular in combination with a cap.

Vorteilhaft ist, wenn die Aussparungen in dem Wärmedämmelement für die Boden- und Deckenbefestigungslaschen so eng ausgebildet sind, dass darüber eine Klemmwirkung eintritt, wenn das Wärmedämmelement auf das Aussteigungselement seitlich aufgeschoben wird.It is advantageous if the recesses in the heat-insulating element for the floor and ceiling fixing straps are formed so narrow that a clamping effect occurs above this when the thermal insulation element is pushed laterally onto the sloping element.

Die bevorzugte Ausrichtung beider Befestigungslaschen zur selben Seite hin hat zudem den Vorteil, dass die rückwärtige Seitenfläche des Verbindungsbügels komplett eben und frei von Vorsprüngen ist. Es kann dann zwar vorgesehen sein, auch an der rückwärtigen Seite ein relativ schmales, angepasstes Wärmedämmelement anzusetzen. Vorzugsweise wird aber der ohnehin im Rollladenkasten vorgesehene Wärmedämmkörper so abgelängt, dass er zwischen dem Stirnseitenelement und dem Aussteifungselement eingepasst ist und sich direkt an das Aussteifungselement anlegt.The preferred orientation of both fastening tabs on the same side also has the advantage that the rear side surface of the connecting bracket is completely flat and free of projections. Although it may then be provided to attach a relatively narrow, adapted thermal insulation element on the rear side. Preferably, however, the already provided in the roller shutter box heat insulation body is cut so that it is fitted between the end side member and the stiffening element and applies directly to the stiffening element.

Auf der anderen Seite schließt sich der längliche Wärmedämmkörper direkt an das erfindungsgemäß vorgesehene Wärmedämmelement an. Bevorzugt sind die Umrisse gleich, so dass sich ein nahtloser Übergang ergibt. Erfindungsgemäß verschwindet dann das Aussteigungselement fast vollständig zwischen den Wärmedämmelementen und Wärmedämmkörpern.On the other hand, the elongated heat-insulating body connects directly to the thermal insulation element provided according to the invention. Preferably, the outlines are the same, resulting in a seamless transition. According to the invention then the Aussteigungselement disappears almost completely between the heat-insulating elements and heat-insulating bodies.

Vorgesehen sein kann, dass der Verbindungsbügel wenigstens einen Verstärkungssteg aufweist, zum Beispiel an der gebäudeinnenseitigen, rückwärtigen Kante, wo er sich rechtwinklig an den Verbindungsbügel anschließt, und dass das Wärmedämmelement eine Aussparung zur Aufnahme des Verstärkungssteges aufweist. Damit wird die Festigkeit des Aussteifungselements gegen Ausknicken erhöht. Zugleich werden die an dem Verstärkungssteg zusätzlichen vorhandenen Oberflächenbereiche wieder vom Wärmedämmelement überdeckt.It can be provided that the connecting bracket has at least one reinforcing web, for example on the building inside, rear edge, where it connects at right angles to the connecting bracket, and that the heat-insulating element has a recess for receiving the reinforcing web. This increases the strength of the stiffening element against buckling. At the same time, the additional surface areas present on the reinforcing web are again covered by the thermal insulation element.

Weiterhin betrifft die Erfindung einen Rollladenkasten mit den Merkmalen des Anspruchs 9, der mit zumindest einem wärmegedämmtem Aussteifungselement nach der Erfindung versehen ist.Furthermore, the invention relates to a roller shutter box with the features of claim 9, which is provided with at least one thermally insulated stiffening element according to the invention.

Unter Rollladenkästen werden erfindungsgemäß auch diejenigen Kästen verstanden, die zur Aufnahme anderer Fenstervorhänge dienen, wie beispielsweise von sogenannten Raffstores, also aus verstellbaren Lamellen gebildete Außenjalousien, oder von Insektenschutzgittern.Under shutter boxes according to the invention, those boxes understood that serve to accommodate other window curtains, such as so-called external blinds, ie formed of adjustable slats exterior blinds, or insect screens.

Besonders bevorzugt ist dabei vorgesehen, dass die Bodenbefestigungslasche und die Deckenbefestigungslasche des Aussteifungselements parallel zueinander angeordnet sind, und dass die Bodenbefestigungslasche und die Deckenbefestigungslaschen sich jeweils an der gleichen Seite des Verbindungsbügels anschließen. Deren Seitenkante sollte sich zudem jeweils zur selben Seite hin öffnen, um wenigstens eine Aufnahmenut für eine Befestigungsschraube zu bilden.Particularly preferably, it is provided that the Bodenbefestigungslasche and the ceiling mounting strap of the stiffening element are arranged parallel to each other, and that the Bodenbefestigungslasche and the Deckenbefestigungslaschen each connect to the same side of the connecting bracket. Their side edge should also open in each case to the same side to form at least one receiving groove for a fastening screw.

Damit ist eine besonders einfache Montage möglich, indem zunächst nur die vorgesehenen Befestigungsschrauben am Boden- bzw. Deckenprofil eingesetzt werden: Hierzu werden zunächst die Wärmedämmkörper aus dem Rollladenkasten entnommen und es wird dann das Wärmedämmelement seitlich vom Aussteifungselement abgezogen, so dass die vorgesehenen Befestigungsstellen leicht zugänglich sind. Die Befestigungsstellen können dabei im Abrollprofil, das auf dem Blendrahmen aufgesetzt ist, vorgefertigt werden, beispielsweise durch in einem bestimmten Abstand eingesetzte Gewindehülsen. Damit ist es nicht mehr notwendig, mit Bohrmaschinen oder dergleichen innerhalb des Rollladenkastens zu arbeiten, um die Befestigungspunkte vorzubereiten. Danach wird das fertig vorbereitete Aussteifungselement mit seinen Befestigungslaschen von der Seite her unter die Schraubenköpfe geschoben. Es müssen dann nur noch die Schrauben angezogen werden, um das Aussteifungselement fest zu montieren. Abschließend werden die Wärmedämmkörper wieder eingesetzt und der Rollladenkasten wird verschlossen.For a particularly simple installation is possible by initially only the proposed mounting screws are used on the floor or ceiling profile: For this purpose, the heat insulation body from the roller shutter box are first removed and it is then deducted from the heat insulation laterally from the stiffening element, so that the intended attachment points easily accessible are. The attachment points can be prefabricated in Abrollprofil, which is placed on the frame, for example, by threaded at a certain distance threaded sleeves. Thus, it is no longer necessary to work with drills or the like within the roller shutter box to prepare the attachment points. Thereafter, the ready-prepared stiffening element is pushed with its attachment tabs from the side under the screw heads. Then only the screws have to be tightened in order to firmly mount the stiffening element. Finally, the heat-insulating body are used again and the shutter box is closed.

Im Revisionsfall erfolgt die Demontage in umgekehrter Reihenfolge. Auch hierbei ist vorteilhaft, dass die rollladenkastenseitigen Befestigungsschrauben nur gelockert, aber nicht vollständig entfernt werden müssen, so dass die erneute Montage später einfacher durchführbar ist.In case of revision, dismantling takes place in reverse order. Here, too, it is advantageous that the roller shutter box-side fixing screws only loosened, but not completely removed, so that the re-assembly is easier to carry out later.

Vorgesehen sein kann auch, dass anstelle von Schrauben im Abrollprofil des Rollladenkastens Gewindebolzen eingesetzt sind, auf denen eine Gewindemutter montiert wird.It can also be provided that instead of screws in the rolling profile of the roller shutter box threaded bolts are used, on which a threaded nut is mounted.

FIG. 1 showed a thermally insulated stiffening element 10, which consists essentially of the connection bracket 12 with ground connection tab 11 and ceiling connection tab 13 and a thermal insulation element 80.

Das Wärmedämmelement 80 besitzt Aussparungen 80.1, 80.3, um die Bodenanschlusslasche 11 und die Deckenanschlusslasche 13 so weit wie möglich einzuhüllen. Das schließt auch Befestigungsmittel mit ein, über welche das Aussteifungselement 10 am Rollladenkasten, am Blendrahmen oder an einer Gebäudedecke befestigt wird.The heat-insulating element 80 has recesses 80.1, 80.3 in order to envelop the ground connection tab 11 and the ceiling connection tab 13 as far as possible. This also includes fastening means with which the stiffening element 10 is fastened to the roller shutter box, to the window frame or to a building ceiling.

Bevor auf die Ausbildung des Aussteifungselements 10 im Einzelnen eingegangen wird, sei zunächst die Lage des Aussteifungselements 10 innerhalb eines Rollladenkastens 100 erläutert, welche in Figur 2 dargestellt ist:

  • Der Rollladenkasten 100 besitzt eine zur Gebäudeaußenseite hingewandte Seitenwand 21 sowie eine zur Gebäudeinnenseite gewandte Seitenwand 23. Nach oben hin ist der Rollladenkasten 100 durch ein Deckenelement 22 abgeschlossen, das über ein ggf. eingefügtes, nicht dargestelltes Verbindungsprofil mit einer Gebäudedecke zu verbinden ist. Unten ist ein Bodenelement 24 vorgesehen, das alternativ oder zusätzlich zur Seitenwand 23 als Revisionsöffnung benutzt werden kann.
Before discussing the formation of the stiffening element 10 in detail, the position of the stiffening element 10 within a roller shutter box 100 is first explained, which in FIG. 2 is shown:
  • The roller shutter box 100 has a side wall facing the building exterior side wall 21 and a side wall facing the building 23. Upwards, the shutter box 100 is closed by a ceiling element 22 which is to be connected via a possibly inserted, not shown connection profile with a building ceiling. Below a bottom element 24 is provided, which can be used as an alternative or in addition to the side wall 23 as a revision opening.

Auf einem Blendrahmen eines Fensters oder einer Tür ist ein zweiteiliges Abrollprofil 60 montiert. Das untere Abrollprofilteil besitzt eine Rundung und stellt Rastaufnahmen für ein oberes Abrollprofilteil bereit. Der zwischen dem unteren und dem oberen Abrollprofilteil gebildete Hohlraum kann zur Aufnahme einer Befestigungsplatte eines Befestigungselements 62 benutzt werden, welches beispielsweise einen Gewindebolzen 64 enthält.On a frame of a window or a door a two-part roll-off profile 60 is mounted. The lower Abrollprofilteil has a rounding and provides locking receptacles for an upper Abrollprofilteil ready. The cavity formed between the lower and upper Abrollprofilteil can be used to receive a mounting plate of a fastener 62, which includes, for example, a threaded bolt 64.

Wie wiederum Figur 1 zeigt, kann die Bodenanschlusslasche 11 des Aussteifungselements 10 über seine L-förmige Nut zunächst am Befestigungselement 62 eingehakt werden und dann mittels der Mutter 63 fest daran angebracht werden. Anschließend wird das Wärmedämmelement 80 von der Seite aufgeschoben. Ein Zusatzwärmedämmelement 81 in Form einer Kappe überdeckt das Ende des Gewindebolzens und die Mutter 63.Like again FIG. 1 shows, the bottom terminal tab 11 of the stiffening member 10 can be hooked via its L-shaped groove first on the fastener 62 and then attached by means of the nut 63 fixed thereto. Subsequently, the thermal insulation element 80 is pushed from the side. An additional heat-insulating member 81 in the form of a cap covers the end of the threaded bolt and the nut 63.

Den vollständigen Montagevorgang in mehreren Schritten zeigen die Figuren 3 bis 7. Zur besseren Darstellung sind von dem Rollladenkasten 100 jeweils nur die bodenseitigen Elemente, nämlich das Bodenelement 24 im Hintergrund und das Abrollprofil 60 im Vordergrund gezeigt.The complete assembly process in several steps show the FIGS. 3 to 7 , For better illustration, only the bottom-side elements, namely the bottom element 24 in the background and the rolling profile 60 in the foreground, are shown in each case by the roller shutter box 100.

In Figur 3 sind bereits zwei Wärmedämmkörper 82, 83 eingesetzt, die sich gegenseitig ergänzen, um die hinten liegende, nicht dargestellte Seitenwand 23 vollständig zu überdecken. In das Abrollprofil ist eine Ausnehmung 61 eingebracht.In FIG. 3 already two heat-insulating bodies 82, 83 are used, which complement each other to completely cover the rear, not shown side wall 23. In the roll-off profile a recess 61 is introduced.

Bei dem nächsten Schritt entsprechend Figur 4 ist ein Befestigungselement 62 in das Abrollprofil eingesetzt bzw. dieses wurde am Blendrahmen eingesetzt, und es wurde dann das Abrollprofil 60 darauf aufgerastet, so dass nur der Gewindebolzen 64 herausschaut. An dem Gewindebolzen 64 ist das Aussteifungselement 10 mit seiner Bodenanschlusslasche 11 eingehakt. Mit der hinteren Seitenfläche liegt das Aussteifungselement 10 an den Wärmedämmkörpern 82, 83 an.In the next step accordingly FIG. 4 a fastener 62 is inserted into the roll-off or this was used on the frame, and it was then the Abrollprofil 60 snapped onto it, so that only the threaded bolt 64 looks out. On the threaded bolt 64, the stiffening element 10 is hooked with its bottom connection tab 11. With the rear side surface, the stiffening element 10 abuts against the heat-insulating bodies 82, 83.

Im nächsten Schritt nach Figur 5 wird die Gewindemutter 63 aufgeschraubt und das Wärmedämmelement 10 wird aufgesetzt.In the next step after FIG. 5 the threaded nut 63 is screwed on and the thermal insulation element 10 is placed.

Somit wird - siehe Figur 6 - das Aussteifungselement 10 schon fast vollständig überdeckt. Lediglich die Oberseite an der Deckenanschlusslasche 13 ragt notwendigerweise heraus. Von der Bodenschlusslasche 11 steht noch ein Teil nach vorn hervor, der mit dem Zusatzwärmedämmelement 81 abgedeckt wird.Thus becomes - see FIG. 6 - The stiffening element 10 already almost completely covered. Only the top on the ceiling connection tab 13 necessarily protrudes. From the bottom end tab 11 is still a part of the front, which is covered with the additional heat insulation element 81.

Das Zusatzwärmedämmelement 81 bewirkt eine Abdichtung im Rollladenkasten. Es bewirkt auch die notwendige Fortführung der Wärmedämmung bzw. hilft, Wärmebrücken zu vermeiden. Damit können die nach den Normen und sonstigen anerkannten Regeln der Technik bestehenden Mindestanforderungen an den U-Wert und den FRSI-Wert eingehalten werden.The additional thermal insulation element 81 effects a seal in the roller shutter box. It also causes the necessary continuation of the thermal insulation or helps to avoid thermal bridges. This allows compliance with the minimum U-value and FRSI requirements set by standards and other recognized technical rules.

Figur 7 zeigt dann alles fertig montiert in perspektivischer Ansicht und Figur 8 den gleichen Zustand in Ansicht von vorn. Das Aussteifungselement 10 ist zwischen den Wärmedämmkörpern 82, 83 und den Wärmedämmelementen 80, 81 unsichtbar. Von dem Innenraum des Rollladenkastens 100 her, entsprechend der Blickrichtung in Figur 8, sind keine Teile des Aussteifungselements 10 mehr sichtbar. Entsprechend wird eine Wärmeleitung über das Aussteifungselements 10 zur rückwärtigen Seite unterbrochen oder zumindest stark reduziert. FIG. 7 then shows everything ready assembled in perspective view and FIG. 8 the same state in front view. The stiffening element 10 is invisible between the heat-insulating bodies 82, 83 and the heat-insulating elements 80, 81. From the interior of the shutter box 100 ago, according to the viewing direction in FIG. 8 , no parts of the stiffening element 10 are more visible. Accordingly, a heat conduction is interrupted via the stiffening element 10 to the rear side or at least greatly reduced.
