Description

Die Erfindung betrifft einen Ziegel-Rolladenkasten mit einem U-förmigen, nach unten offenen Querschnitt, bestehend aus mehreren, untereinander und mit in Längsrichtung des Kastens angeordneten Bewehrungsstäben durch Mörtel verbundenen, mit Hohlräumen versehenen Ziegelformsteinen, durch welche zwei zueinander parallele Seitenwände, eine diese oben verbindende Decke und zwei stirnseitige, mit den Seitenwänden und der Decke verbundene Stirnplatten des Kastens gebildet sind, wobei die Ziegelformsteine zur Aufnahme der Bewehrungsstäbe in Längsrichtung des Kastens verlaufende Aussparungen, einschließlich am unteren Rand jeder Seitenwand vorgesehenen, nach unten offenen U-förmigen Aussparungen aufweisen und ihre Hohlräume mit Hartschaumstoff gefüllt sind.The invention relates to a brick roller shutter box with a U-shaped, downwardly open cross section, consisting of several, with each other and arranged in the longitudinal direction of the box reinforcement bars connected by mortar, provided with cavities shaped bricks, through which two mutually parallel side walls, one of them above connecting ceiling and two end face plates of the box connected to the side walls and the ceiling are formed, the brick blocks for receiving the reinforcing bars having recesses running in the longitudinal direction of the box, including U-shaped recesses provided at the lower edge of each side wall and their cavities are filled with rigid foam.

Ein derartiger bekannter Ziegel-Rolladenkasten (siehe DE-B-25 36 086) besteht aus mehreren, stirnseitig aneinandergestoßenen Ziegelformsteinen mit L-förmigem Querschnitt. Die Ziegelformsteine sind spiegelbildlich zu einer vertikalen Längsmittelebene des Rolladenkastens angeordnet, wobei ihre kürzeren L-Schenkel oben liegen und deren freie Enden einander zugekehrt sind. Zwischen den freien Enden der kürzeren L-Schenkel ist eine breitere Fuge vorhanden, die mit Mörtel gefüllt ist. Die beiden kürzeren L-Schenkel bilden jeweils einen Teil der Decke, während die nach unten gerichteten längeren L-Schenkel jedes Ziegelformsteines einen Teil der Seitenwand bilden. An ihren einander zugekehrten Stoßflächen sind die Ziegelformsteine ebenfalls durch Mörtel miteinander verbunden. Die Ziegelformsteine sind nach Art von Langlochziegeln mit Hohlräumen versehen, die mit Hartschaumstoff ausgeschäumt sein sollen. In der Praxis wird jedoch dieses Ausschäumen nicht durchgeführt, da es offensichtlich zu teuer ist. Die Ziegelformsteine sind nämlich verhältnismäßig kurz und weisen außerdem eine Vielzahl von Langlöchern auf. Das Ausschäumen dieser Vielzahl von Langlöchern würde einen erheblichen Arbeitsaufwand bedeuten. Da in der Praxis die Hohlräume also nicht ausgeschäumt sind, weist der bekannte Rolladenkasten eine geringe Wärmedämmung auf. Diese geringe Wärmedämmung ist auch dadurch bedingt, daß an den quer zur Achse des Rolladenkastens verlaufenden Stoßflächen der Ziegel eine verhältnismäßig breite Fuge vorhanden ist, die mit Mörtel gefüllt ist. Der verwendete Zementmörtel bildet,ebenso wie die an den Stirnseiten des Rolladenkastens verwendete Stirnplatte aus Massiv-Ziegel, eine Kältebrücke. Damit die Ziegelformsteine beim Trocknen und anschließenden Brennen einigermaßen ihre Form behalten und damit der Rolladenkasten nach dem Zusammenfügen der einzelnen Ziegelformsteine die erforderliche Festigkeit aufweist, haben die Ziegelformsteine quer zur Längsachse des Rolladenkastens verhältnismäßig große Abmessungen. Bei einer vorgegebenen Aussenbreite und Aussenhöhe sind infolgedessen die lichten Innenabmessungen des Rolladenkastens im sogenannten Rollraum verhältnismäßig klein. Der Rollraum wird auch noch dadurch verkleinert, daß wegen der schlechten Wärmedämmung der Ziegelformsteine im Rollraum noch eine Schicht aus Hartschaumstoff vorgesehen ist. Wegen des tatsächlich zur Verfügung stehenden kleinen Rollraumes müssen für den Rolladen besonders platzsparende teuere Miniprofile verwendet werden. Hinzu kommt noch, daß man bei der Herstellung des Rolladenkastens jeweils Mörtel auf die aneinanderstoßenden, quer zur Längsachse des Rolladenkastens verlaufenden Stoßflächen der Ziegelformsteine auftragen muß. Da dieses Auftragen und das Zusammensetzen des Rolladenkastens verhältnismäßig lange Zeit in Anspruch nimmt und außerdem auch verhältnismäßig viel Mörtel erfordert, kann man nur langsam abbindenden Zementmörtel verwenden. Wegen der langen Abbindezeit des Betons ergeben sich lange Fertigungszeiten und daher auch ein Bedarf an verhältnismäßig großen Produktionsstätten.Such a known brick roller shutter box (see DE-B-25 36 086) consists of several brick blocks with an L-shaped cross section butted against one another on the end face. The shaped bricks are mirror images of a vertical longitudinal center plane of the roller shutter box, with their shorter L-legs lying on top and the free ends of which face each other. There is a wider joint between the free ends of the shorter L-legs, which is filled with mortar. The two shorter L-legs each form part of the ceiling, while the downward longer L-legs of each brick form part of the side wall. The shaped bricks are also connected to each other by mortar on their facing abutting surfaces. In the manner of elongated perforated bricks, the shaped bricks are provided with cavities that are to be filled with rigid foam. In practice, however, this foaming is not carried out because it is obviously too expensive. The bricks are relatively short and also have a large number of elongated holes. The foaming of this large number of elongated holes would mean a considerable amount of work. Because in practice the cavities are not foamed, the known roller shutter box has a low thermal insulation. This low thermal insulation is also due to the fact that a relatively wide joint is present on the abutting surfaces of the bricks running transversely to the axis of the roller shutter box, which joint is filled with mortar. The cement mortar used, like the end plate made of solid brick on the front of the roller shutter box, forms a cold bridge. So that the shaped bricks keep their shape to a certain extent during drying and subsequent firing and so that the roller shutter box has the required strength after the individual shaped bricks have been assembled, the shaped bricks have relatively large dimensions transverse to the longitudinal axis of the shutter box. For a given outside width and outside height, the clear inside dimensions of the roller shutter box in the so-called rolling room are consequently relatively small. The roll room is also reduced in that a layer of rigid foam is provided in the roll room because of the poor thermal insulation of the brick blocks. Because of the small roll space that is actually available, particularly space-saving, expensive mini profiles must be used for the roller shutters. In addition, in the manufacture of the roller shutter box, mortar must be applied to the abutting abutting surfaces of the brick blocks running transversely to the longitudinal axis of the roller shutter box. Since this application and assembly of the roller shutter box takes a relatively long time and also requires a relatively large amount of mortar, it is only possible to use slowly setting cement mortar. Because of the long setting time of the concrete, there are long production times and therefore a need for relatively large production sites.

Der Erfindung liegt die Aufgabe zugrunde, einen Ziegel-Rollladenkasten der eingangs erwähnten Art zu schaffen, der eine gute Wärmedämmung und bei gleichen Aussenabmessungen trotzdem einen verhältnismäßig großen Rollraum aufweist. Darüberhinaus soll die Fertigung des Rolladenkastens vereinfacht und damit die Herstellungskosten gesenkt werden. Außerdem soll auch ein Verfahren aufgezeigt werden, welches eine rationelle Fertigung des Ziegel-Rolladenkastens ermöglicht.The invention has for its object to provide a brick roller shutter box of the type mentioned, which has good thermal insulation and still has a relatively large rolling space with the same external dimensions. Furthermore the manufacture of the roller shutter box is to be simplified and thus the manufacturing costs are reduced. In addition, a method is also to be demonstrated which enables rational manufacture of the brick roller shutter box.

Der Rolladenkasten nach der Erfindung ist dadurch gekennzeichnet, daß die Seitenwände, die Decke und gegebenenfalls die Stirnplatten aus ebenen Ziegelplatten bestehen, die nach Art von Stegplatten, je bestehend aus einer ebenen Außenwand, einer mit Abstand von dieser angeordneten ebenen Innenwand und mehreren dazwischen vorgesehenen, senkrecht zu diesen verlaufenden Stegen ausgebildet sind, und daß am oberen Rand der Seitenwandplatten jeweils im wesentlichen rechtwinklige, nach oben und zu den Deckenplatten hin offene Aussparungen (Falze) vorgesehen sind, in die die Enden der Deckenplatten eingreifen, in die die Bewehrungsstäbe eingelegt sind und die mit Mörtel gefüllt sind, wobei die Hohlräume jeweils durch die Außenwand, die Innenwand und die Stege gebildet sind.The roller shutter box according to the invention is characterized in that the side walls, the ceiling and possibly the end plates consist of flat brick plates which, in the manner of web plates, each consisting of a flat outer wall, a flat inner wall arranged at a distance from this and several provided in between, are formed perpendicular to these extending webs, and that at the upper edge of the side wall panels each substantially rectangular, upwards and towards the ceiling panels open recesses (folds) are provided, in which engage the ends of the ceiling panels, in which the reinforcing bars are inserted and which are filled with mortar, the cavities being formed by the outer wall, the inner wall and the webs.

Die für die Herstellung des Rolladenkastens verwendeten Ziegel-Stegplatten können mit verhältnismäßig geringer Dicke von 27 bis 35 mm und trotzdem verhältnismäßig grosser Breite und Längen von über einem Meter maßhaltig und formgenau hergestellt werden. Wegen der verhältnismäßig geringen Dicke der Ziegel-Stegplatten kann der Rollraum verhältnismäßig große lichte Abmessungen aufweisen,und es können deshalb Rolladen ohne die Verwendung von teueren Miniprofilen in den Rolladenkasten montiert werden. Bei einer Außenbreite von beispielsweise 30 cm beträgt die Rollraumbreite 23 cm. Da diese Rollraumbreite mehr als ausreichend ist, kann man sogar an der Innenseite der einen Seitenwandplatte noch eine Platte aus Hartschaumstoff anordnen und damit die Wärmedämmung noch verbessern. Auch ohne diese zusätzliche Hartschaumplatte hat der neue Ziegel-Rolladenkasten eine ausgezeichnete Wärmedämmung. Die zwischen der Außenwand und der Innenwand sowie den Stegen der Ziegel-Stegplatten gebildeten Hohlräume sind verhältnismäßig groß und können deshalb leicht mit Hartschaumstoff gefüllt werden, wobei auch die gegenüber den herkömmlichen Ziegelformsteinen größeren Längen und Breiten der verwendeten Ziegel-Stegplatten das Füllen der Hohlräume mit Hartschaumstoff begünstigen. Außerdem zeichnet sich der neue Rolladenkasten durch ein verhältnismäßig geringes Gewicht und eine hohe Steifigkeit aus.The brick multi-wall sheets used for the manufacture of the roller shutter box can be manufactured with a relatively small thickness of 27 to 35 mm and nevertheless a relatively large width and length of over one meter, true to size and accurate in shape. Because of the relatively small thickness of the multi-wall sheets, the rolling space can have relatively large clear dimensions, and therefore roller shutters can be installed in the roller shutter box without the use of expensive mini profiles. With an outside width of 30 cm, for example, the roll room width is 23 cm. Since this roll room width is more than sufficient, you can even arrange a plate made of rigid foam on the inside of one side wall panel and thus the thermal insulation improve. Even without this additional hard foam panel, the new brick roller shutter box has excellent thermal insulation. The cavities formed between the outer wall and the inner wall and the webs of the brick wall panels are relatively large and can therefore be easily filled with rigid foam, which also compared to the Conventional shaped bricks of greater lengths and widths of the used multi-wall sheets favor the filling of the cavities with rigid foam. In addition, the new roller shutter box is characterized by its relatively low weight and high rigidity.

Ein vorteilhaftes Verfahren zur Herstellung des erfindungsgemäßen Rolladenkastens besteht darin, daß in die rechtwinkligen Aussparungen der lotrecht angeordneten Seitenwandplatten die Deckenplatten und die Bewehrungsstäbe von oben her eingelegt werden, dann die zwischen den Enden der Deckenplatten und den Aussparungen vorhandenen Fugen mit Mörtel ausgegossen werden, nach dem Abbinden des Mörtels der Rollladenkasten um 180° gedreht, in die nunmehr nach oben gerichteten U-förmigen Aussparungen die Bewehrungsstäbe eingelegt und anschließend die U-förmigen Aussparungen mit Mörtel ausgegossen werden.An advantageous method for producing the roller shutter box according to the invention is that the ceiling panels and the reinforcing bars are inserted from above into the rectangular recesses of the perpendicularly arranged side wall panels, then the joints between the ends of the ceiling panels and the recesses are poured with mortar, after which Setting the mortar of the roller shutter box rotated by 180 °, the reinforcing bars are inserted into the now upward-facing U-shaped recesses and then the U-shaped recesses are poured out with mortar.

Wie man aus Fig. 1 erkennen kann, weist der Ziegel-Rolladenkasten einen im wesentlichen U-förmigen, nach unten offenen Querschnitt auf. Die Seitenwände, die Decke und die Stirnplatten bestehen aus hohlen Ziegelplatten 2, 3, 4, die nach Art von Stegplatten ausgebildet sind. Wie man aus der Zeichnung erkennen kann, besteht jede dieser Ziegelplatten aus einer Aussenwand 2a, 3a, 4a, einer mit Abstand von der Aussenwand angeordneten Innenwand 2b, 3b, 4b und dazwischen angeordneten, senkrecht zu den beiden Wänden 2a, 3a, 4a bzw. 2b, 3b, 4b verlaufenden Stegen 2c, 3c, 4c. Derartige Ziegel-Stegplatten können mit entsprechenden Mundstücken im Strangpressverfahren hergestellt werden. Zwischen der Aussenwand 2a, 3a, 4a, der Innenwand 2b, 3b, 4b und den Stegen 2c, 3c, 4c sind verhältnismäßig große Hohlräume 2d, 3d, 4d von rechteckigem Querschnitt vorhanden. Diese Hohlräume sind mit Hartschaumstoff 5 gefüllt. Das Füllen erfolgt zweckmäßig so, daß aus einer Hartschaumstoffplatte entsprechender Dicke Streifen geschnitten werden, die in die Hohlräume eingesteckt werden. Es ist auch denkbar, die Hohlräume gegebenenfalls mit flüssigem Hartschaumstoff auszuschäumen. Dank des Hartschaumstoffes 5 haben die Ziegel-Stegplatten eine hohe Wärmedämmung. Außerdem verleihen die Ziegel-Stegplatten dem fertigen Rolladenkasten ein geringes Gewicht.As can be seen from Fig. 1, the brick roller shutter box has a substantially U-shaped cross-section open at the bottom. The side walls, the ceiling and the end plates consist of hollow brick plates 2, 3, 4, which are designed in the manner of web plates. As can be seen from the drawing, each of these tiles consists of an outer wall 2a, 3a, 4a, one at a distance from the Outside wall arranged inside wall 2b, 3b, 4b and arranged between them, perpendicular to the two walls 2a, 3a, 4a and 2b, 3b, 4b, webs 2c, 3c, 4c. Brick multi-wall sheets of this type can be produced with corresponding mouthpieces in the extrusion process. Between the outer wall 2a, 3a, 4a, the inner wall 2b, 3b, 4b and the webs 2c, 3c, 4c there are relatively large cavities 2d, 3d, 4d of rectangular cross-section. These cavities are filled with rigid foam 5. The filling is expediently carried out in such a way that strips are cut from a rigid foam sheet of appropriate thickness and inserted into the cavities. It is also conceivable to foam the cavities with liquid rigid foam if necessary. Thanks to the rigid foam 5, the multi-wall sheets have high thermal insulation. In addition, the multi-wall sheets give the finished roller shutter box a low weight.

Am oberen Rand der Seitenwandplatten 2 ist jeweils eine im wesentlichen rechteckige Aussparung 6, die auch als Falz bezeichnet werden kann, vorgesehen. Ebenso ist die Stirnplatte 4 mit einer gleichartigen Aussparung 7 versehen. Die Höhe h der rechteckigen Aussparungen 6, 7 entspricht etwa der Dicke d der Deckenplatten 3. Die Deckenplatten 3 greifen mit ihren Enden 3′ in die Aussparungen 6 der Seitenwandplatten 2 ein. Ebenso greift der Rand 3˝ der an die Stirnplatte 4 angrenzenden Deckenplatte in die Aussparung 7 derselben ein. Zweckmäßig ist dabei an dem der Innenseite der Seitenwandplatten 2 zugekehrten Ende der Ausparungen 6 ein nach oben ragender Absatz 8 vorgesehen, auf welchem das Ende 3′ der Deckenplatte 3 aufliegt. Ein gleichartiger Absatz 9 ist auch bei der Aussparung 7 der Stirnplatte 4 vorgesehen. Dank dieser Absätze 8,9 kann der in die Ausparungen 6, 7 eingefüllte Mörtel auch an einen Teil der Unterseite der Deckenplatten 3 gelangen, so daß die Verbindungsfläche zwischen dem Mörtel und der Deckenplatte vergrößert und die Stabilität des Rolladenkastens verbessert wird.At the upper edge of the side wall panels 2 there is a substantially rectangular recess 6, which can also be referred to as a fold. The end plate 4 is also provided with a similar recess 7. The height h of the rectangular recesses 6, 7 corresponds approximately to the thickness d of the ceiling panels 3. The ceiling panels 3 engage with their ends 3 'in the recesses 6 of the side wall panels 2. Likewise, the edge 3˝ of the ceiling plate adjacent to the end plate 4 engages in the recess 7 of the same. Appropriately, an upwardly projecting shoulder 8 is provided on the inside of the side wall panels 2 facing the end of the recesses 6, on which the end 3 'of the ceiling panel 3 rests. A similar paragraph 9 is also provided in the recess 7 of the end plate 4. Thanks to these paragraphs 8.9, the mortar filled into the recesses 6, 7 can also reach part of the underside of the ceiling panels 3, so that the connection area between the mortar and the ceiling panel is enlarged and the stability of the roller shutter box is improved.

In die Aussparungen 6 der Seitenwandplatten 2 sind ferner Bewehrungsstäbe 11 aus sogenanntem Rippenstahl eingelegt, die sich über die gesamte Länge des Rolladenkastens erstrecken. Diese Bewehrungsstäbe 11 sind von dem Mörtel 10 ummantelt. Die Breite b der rechtwinkligen Aussparungen 6 ist etwas größer als die Länge 1 des jeweils in die Aussparungen 6 eingreifenden Endes 3′ der Deckenplatten 3 zuzüglich dem Durchmesser des Bewehrungsstabes 11. Die Länge 1 sollte dabei etwa der halben Dicke d1 der Seitenwandplatten entsprechen.In the recesses 6 of the side wall panels 2 reinforcement bars 11 made of so-called rib steel are also inserted, which extend over the entire length of the roller shutter box. These reinforcing bars 11 are covered by the mortar 10. The width b of the rectangular recesses 6 is slightly larger than the length 1 of the respectively engaging in the recesses 6 end 3 'of the ceiling panels 3 plus the diameter of the reinforcing bar 11. The length 1 should correspond to approximately half the thickness d1 of the side wall panels.

Die Seitenwandplatten 2 sind an ihren unteren Rändern mit im wesentlichen U-förmigen, nach unten hin offenen Aussparungen 12 versehen. In diesen Aussparungen 12 sind Bewehrungsstäbe 13 angeordnet und außerdem können in diese Aussparungen auch die Halteschenkel von Aluminium-Abschlußprofilen 14, 15 eingreifen. Auch die U-förmigen Aussparungen 12 sind mit Mörtel gefüllt, der die Bewehrungstäbe 13 ummantelt.The side wall panels 2 are provided at their lower edges with substantially U-shaped, downwardly open recesses 12. Reinforcing bars 13 are arranged in these recesses 12 and the holding legs of aluminum end profiles 14, 15 can also engage in these recesses. The U-shaped recesses 12 are also filled with mortar, which encases the reinforcing bars 13.

Die Deckenplatten 3 sind gegenüber den Seitenwandplatten 2 zweckmäßig so angeordnet, daß die Stege 3c der Deckenplatten senkrecht zu den Seitenwandplatten 2 verlaufen. Die Stege 3c verleihen nämlich den Ziegel-Stegplatten in der Richtung in der sie verlaufen, eine höhere Festigkeit, als in einer Richtung quer zu den Stegen. Auf diese Weise erhält der Rolladenkasten eine optimale Festigkeit. Die Breite B der Deckenplatten 3 entspricht zweckmäßig dem üblichen Ziegel-Normmaß von 25 cm. Durch Anordnung einer mehr oder weniger großen Anzahl von Deckenplatten nebeneinander, können somit Rolladenkästen in Längenabstufungen von 25 cm hergestellt werden. Um den Rolladenkasten in den gängigsten Mauerwerksdicken herstellen zu können, werden die Deckenplatten 3 und die Stirnplatten 4 von Ziegel-Stegplatten größerer Länge abgeschnitten. Die Aussparungen 6, 7 und 12 können dank der in den Ziegel-Stegplatten vorhandenen Hohlräume durch entsprechende Sägeschnitte in einfacher Weise hergestellt werden.The ceiling panels 3 are advantageously arranged opposite the side wall panels 2 so that the webs 3c of the ceiling panels run perpendicular to the side wall panels 2. The webs 3c give the brick wall panels in the direction in which they run a higher strength than in a direction transverse to the webs. In this way, the roller shutter box is given optimum strength. The width B of the ceiling tiles 3 suitably corresponds to the usual brick standard dimension of 25 cm. By arranging a more or less large number of ceiling panels next to each other, roller shutter boxes can be manufactured in 25 cm increments. In order to be able to manufacture the roller shutter box in the most common masonry thicknesses, the ceiling panels 3 and the end panels 4 are cut off from multi-wall bricks. The recesses 6, 7 and 12 can be made easier by appropriate saw cuts thanks to the cavities present in the brick wall panels Way to be made.

Ziegel-Stegplatten können in Längen von über einem Meter hergestellt werden. Aus diesem Grund ist es zweckmäßig, die Seitenwandplatten so anzuordnen, daß ihre Stege 2c in Längsrichtung des Rolladenkastens verlaufen. Jede Seitenwand des Rolladenkastens kann infolgedessen aus verhältnismäßig wenigen Seitenwandplatten 2 bestehen. Es ergeben sich zwischen zwei benachbarten Seitenwandplatten deshalb auch nur verhältnismäßig wenige Stoßstellen. Diese Stoßstellen sollten genauso wie die Stoßstellen zwischen den Rändern 3˝ zweier benachbarter Deckenplatten nicht mit Mörtel gefüllt sein, um Kältebrücken zu vermeiden. Ziegel-Stegplatten können mit so großer Genauigkeit hergestellt bzw. geschnitten werden, daß zwischen benachbarten Deckenplatten 3 bzw. Seitenplatten 2 nur Fugen minimaler Breite vorhanden sind.Tile multi-skin sheets can be produced in lengths of over one meter. For this reason, it is expedient to arrange the side wall panels so that their webs 2c run in the longitudinal direction of the roller shutter box. As a result, each side wall of the roller shutter box can consist of relatively few side wall panels 2. There are therefore only relatively few joints between two adjacent side wall panels. These joints, like the joints between the edges 3˝ of two adjacent ceiling tiles, should not be filled with mortar to avoid cold spots. Tile multi-wall sheets can be produced or cut with such great accuracy that only joints of minimal width are present between adjacent ceiling panels 3 or side panels 2.

Die Stirnplatten 4 weisen an ihren senkrechten Rändern zweckmäßig ebenfalls rechtwinklige Aussparungen 16 auf, in welche die Enden 2′ der Seitenwandplatten 2 eingreifen. Die zwischen den Enden 2′ und den Aussparungen 16 verbleibenden Fugen sind ebenfalls mit Mörtel 10 gefüllt.The end plates 4 expediently also have rectangular recesses 16 in their vertical edges, in which the ends 2 'of the side wall plates 2 engage. The joints remaining between the ends 2 'and the recesses 16 are also filled with mortar 10.

Der Mörtel 10 besteht zweckmäßig aus einem Zwei-Komponenten-Kunstharz und Quarzsand. Dieser Mörtel kann nach dem Zusammensetzen des Rolladenkastens nachträglich in die Aussparungen 6, 7, 12 und 16 eingespritzt werden. Er bindet innerhalb einer verhältnismäßig kurzen Zeit von ca. einer halben Stunde ab, wodurch die Herstellung sehr beschleunigt wird und der Bedarf an Produktionsflächen verringert wird. Außerdem verleiht der aus Zwei-Komponenten-Kunstharz und Quarzsand bestehende Mörtel dem Rolladenkasten eine hohe Festigkeit und Biegesteifigkeit.The mortar 10 suitably consists of a two-component synthetic resin and quartz sand. This mortar can be injected into the recesses 6, 7, 12 and 16 after assembling the roller shutter box. It sets within a relatively short time of around half an hour, which speeds up production and reduces the need for production space. In addition, the mortar, which consists of two-component synthetic resin and quartz sand, gives the roller shutter box a high level of strength and flexural strength.

Gegebenenfalls wäre es auch denkbar, anstelle des beschriebenen Mörtels auch einen sogenannten Kunstharz-Mörtel zu verwenden, der aus Zement, Ein-Komponenten-Kunstharz, wie z. B. Polyvinylacetat, Wasser und Quarzsand besteht. Der eingangs beschriebene Mörtel mit Zwei-Komponenten-Kunstharz ist jedoch wegen der rascheren Abbindezeit und seinem höheren Haftvermögen an den verhältnismäßig glatten Schnittstellen und Oberflächen der Ziegel-Stegplatten vorzuziehen.If necessary, it would also be conceivable to use a so-called synthetic resin mortar instead of the described mortar, which consists of cement, one-component synthetic resin, such as e.g. B. polyvinyl acetate, water and quartz sand. The mortar with two-component synthetic resin described at the outset is, however, preferable because of the faster setting time and its higher adhesion to the relatively smooth interfaces and surfaces of the multi-wall sheets.

Weiterhin ist es zweckmäßig, in der Nähe der beiden Stirnplatten 4 des Rolladenkastens 1 je ein, die zugehörige Deckenplatte 3 überspannendes Trageband 17 vorzusehen. Die Enden 17′ dieses Tragebandes sind in die rechtwinkligen Aussparungen 6 der Seitenwandplatten 2 eingesteckt und um die Bewehrungsstäbe 11 geschlungen. Hierdurch wird beim anschließenden Ausgießen der Aussparungen 6 mit dem Mörtel 10 auch eine feste Verbindung der Enden 17′ des Tragebandes 17 mit dem Rolladenkasten 1 erreicht.Furthermore, it is expedient to provide a carrying strap 17 spanning the associated ceiling panel 3 in the vicinity of the two end panels 4 of the roller shutter box 1. The ends 17 'of this lanyard are inserted into the rectangular recesses 6 of the side wall panels 2 and looped around the reinforcing bars 11. As a result, when the recesses 6 are subsequently poured out with the mortar 10, a firm connection of the ends 17 'of the carrying band 17 to the roller shutter box 1 is also achieved.

In den Stirnplatten 4 sind zweckmäßig Bohrungen 18 für Schrauben 19 vorgesehen, deren Schraubenköpfe 19a in den Hohlräumen 4d der Stirnplatten 4 angeordnet sind. Der die Schraubenköpfe 19a umgebende Teil der Hohlräume 4d ist mit Mörtel 10 ausgefüllt, so daß die Schrauben 19 in den Bohrungen 18 gehalten und gegen Drehung gesichert sind. Die an der Innenseite der Stirnplatten 4 vorstehenden Schrauben, dienen, ähnlich wie Stehbolzen, zur Befestigung einer nicht dargestellten Konsole, welche zur Lagerung der Achse des Rolladens dient.Bores 18 for screws 19 are expediently provided in the end plates 4, the screw heads 19 a of which are arranged in the cavities 4 d of the end plates 4. The part of the cavities 4d surrounding the screw heads 19a is filled with mortar 10 so that the screws 19 are held in the bores 18 and secured against rotation. The screws protruding on the inside of the end plates 4 serve, similar to stud bolts, for fastening a bracket (not shown) which serves to support the axis of the roller shutter.

Die Herstellung des Rolladenkastens erfolgt zweckmäßig wie folgt:
An den Ziegel-Stegplatten werden zunächst die Aussparungen 6, 7 und 12 gesägt, dann werden die Stegplatten durch Sägen auf die passenden Längen geschnitten. An den Stirnplatten 4 werden außerdem die Aussparungen 16 gesägt. Die Seitenwandplatten 2 werden dann in lotrechter Stellung, die sie auch beim fertigen Rolladen einnehmen, beispielsweise in einer Schablone aufgestellt. Ebenso können die Stirnplatten 4 lotrecht aufgestellt werden. In die nach oben offenen Aussparungen 6 der Seitenwandplatten 2 werden dann die Deckenplatten 3 eingelegt, wobei sie sich auf den Absätzen 8 bzw. 9 abstützen. In die Aussparungen 6 werden dann außerdem die Bewehrungstäbe 11 eingelegt. Anschließend werden die Aussparungen 6, 7 und 16 mit Mörtel ausgespritzt. Nach dem Abbinden des kunstharzgebundenen Mörtels kann man nach ca. einer halben Stunde den Rolladenkasten um seine Längsachse um 180° drehen, so daß nunmehr die beim fertigen Rolladenkasten unten liegenden U-förmigen Aussparungen nach oben gerichtet und nach oben offen sind. In diese U-förmigen Aussparungen 12 wird der Mörtel 10 eingespritzt und dann werden die Bewehrungsstäbe 13 eingedrückt. Die Abschlußleisten (Putzschienen) 14 und 15 werden anschließend mit ihren Halteschenkeln in den noch plastischen Mörtel 10 eingedrückt.The roller shutter box is conveniently manufactured as follows:
The cutouts 6, 7 and 12 are first sawn on the brick multi-wall sheets, then the multi-wall sheets are cut to the appropriate lengths by sawing. The cutouts 16 are also sawn on the end plates 4. The side wall panels 2 are then set up in a vertical position, which they also assume in the finished roller shutter, for example in a template. The end plates can also be used 4 be set up vertically. The ceiling panels 3 are then inserted into the upwardly open recesses 6 of the side wall panels 2, whereby they are supported on the shoulders 8 and 9, respectively. The reinforcement bars 11 are then also inserted into the recesses 6. Then the recesses 6, 7 and 16 are sprayed with mortar. After the resin-bound mortar has set, you can turn the roller shutter box about its longitudinal axis by 180 ° after about half an hour, so that the U-shaped recesses lying underneath in the finished roller shutter box are now directed upwards and open at the top. The mortar 10 is injected into these U-shaped recesses 12 and then the reinforcing bars 13 are pressed in. The end strips (plaster rails) 14 and 15 are then pressed with their holding legs into the still plastic mortar 10.

Da die zur Herstellung des Ziegel-Rolladenkastens 1 verwendeten Ziegel-Stegplatten eine verhältnismäßig geringe Wanddicke d von 27 mm bzw. d1 von 35 mm aufweisen, ergibt sich im Innern des Rolladenkastens 1 ein verhältnismäßig großer Rollraum, der zur Aufnahme von Rolläden mit üblichen Lamellenprofilen geeignet ist. Dar Rollraum ist sogar so groß, daß zusätzlich noch eine Platte 20 aus Hartschaumstoff an der Innenseite der einen Seitenwandplatte 2 angeordnet sein kann. Hierdurch kann der an sich schon niedrige k-Wert des Rolladenkastens noch weiter gesenkt werden.Since the multi-wall sheets used to manufacture the brick roller shutter box 1 have a relatively small wall thickness d of 27 mm or d1 of 35 mm, a relatively large rolling space results in the interior of the roller shutter box 1, which is suitable for receiving roller shutters with conventional slat profiles is. The rolling space is even so large that a plate 20 made of rigid foam can additionally be arranged on the inside of one side wall plate 2. As a result, the already low k-value of the roller shutter box can be reduced even further.

Gegebenenfalls könnten die Stirnplatten auch aus Ziegel-Formteilen bestehen. In diesem Fall würden die rechtwinkligen Aussparungen 7, 16 beim Pressen des Tones unmittelbar geformt werden. Anstelle von Hohlräumen würde die Stirnplatte nach innen vorstehende Rippen aufweisen, zwischen die zur Verbesserung der Wärmedämmung Hartschaumstoffstreifen eingelegt werden könnten.If necessary, the end plates could also consist of molded brick parts. In this case, the rectangular recesses 7, 16 would be formed immediately when the clay was pressed. Instead of cavities, the end plate would have ribs projecting inwards, between which rigid foam strips could be inserted to improve the thermal insulation.

Weiterhin ist es auch möglich, die Deckenplatten so anzuordnen, daß ihre Stege in Längsrichtung des Rolladenkastens verlaufen. Dies ist besonders bei Rolladenkästen größerer Länge von Vorteil.Furthermore, it is also possible to arrange the ceiling panels so that their webs in the longitudinal direction of the roller shutter box run. This is particularly advantageous for roller shutter boxes of greater length.

Man könnte auch zunächst einen Kasten herstellen, der nur aus den Seitenwandplatten und Deckenplatten besteht und eine Länge von beispielsweise 6m aufweist. Von diesem Kasten können dann Abschnitte in der Länge des jeweils bestellten Rolladenkastens abgesägt werden. Diese Abschnitte werden nach dem Absägen mit Stirnplatten versehen. Die 6 m langen Kästen könnten auch an Rolladenhersteller geliefert werden, die dann selbst Abschnitte in der jeweils gewünschten Länge abschneiden und mit Stirnplatten versehen. Auf diese Weise braucht ein Rolladenhersteller nicht verschiedene Längen von Rolladenkästen auf Lager zu halten.One could also first produce a box that only consists of the side wall panels and ceiling panels and has a length of, for example, 6 m. Sections of the length of the roller shutter box ordered in each case can then be sawn off from this box. These sections are provided with end plates after sawing off. The 6 m long boxes could also be supplied to roller shutter manufacturers, who then cut off sections of the desired length and provided them with end plates. In this way, a shutter manufacturer does not have to keep different lengths of shutter boxes in stock.
