Description

Die Erfindung betrifft ein Feuerschutzrolltor mit einem Rolladen mit zwei äußeren, im Abstand zueinander angeordneten Schichten aus Stahlblechlamellen, zwischen denen mindestens eine Schicht aus Isoliermatten angeordnet ist, und bei dem die Gelenke zwischen den Stahlblechlamellen an deren Längsrändern in Form von ineinandergreifenden gekrümmten Streifen angeformt sind.The invention relates to a fire protection roller shutter with a roller shutter with two outer, spaced layers of sheet steel plates, between which at least one layer of insulating mats is arranged, and in which the joints between the sheet steel plates are formed on their longitudinal edges in the form of interlocking curved strips.

Bekannt sind als Zweiwellenanlagen ausgebildete Doppelpanzer-Rolltore (DE-B-16 59 775) mit zwei hintereinander angeordneten Rolltoren mit eigenen Antriebsrollen (DE-B-23 49 026). Im letzteren Fall bestehen die Rolltore aus Stahlblechlamellen, zwischen denen mindestens eine Schicht aus Isoliermatten angeordnet ist, und bei denen die Gelenke zwischen den Stahlblechlamellen an deren Längsrändern in Form von ineinandergreifenden gekrümmten Streifen angeformt sind.Double-armored roller doors (DE-B-16 59 775) designed as two-shaft systems with two roller doors arranged one behind the other with their own drive rollers are known (DE-B-23 49 026). In the latter case, the roller shutters consist of sheet steel slats, between which at least one layer of insulating mats is arranged, and in which the joints between the sheet steel slats are formed on their longitudinal edges in the form of interlocking curved strips.

Der Erfindung liegt die Aufgabe zugrunde, mit einer Einwellenanlage praktisch die Wirkung einer feuerbeständigen Doppelpanzeranlage zu erzielen, die für alle Zulassungsklassen geeignet ist.The invention has for its object to achieve practically the effect of a fire-resistant double armor system with a single-shaft system, which is suitable for all classes of approval.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die beiden äußeren Schichten aus Stahlblechlamellen äußere Abschnitte eines Rolladens sind, der aus einem durchgehenden Stück besteht und mit Hilfe eines mittleren, ebenfalls aus den Stahlblechlamellen gebildeten Abschnitts einen unten geschlossenen Doppelpanzer bildet, der zusammen mit den an seinen Abschnitten innen anliegenden Isoliermatten mit einem Ende in bekannter Weise an der Rohrwelle, mit dem anderen Ende an der Decke befestigt ist, in Ruhestellung auf der Welle aufgewickelt ist und in Betriebsstellung mit dem mittleren Abschnitt auf dem Boden aufliegt. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved in that the two outer layers of sheet steel slats are outer sections of a roller shutter, which consists of a continuous piece and with the help of a central section also formed from the sheet steel slats forms a closed double armor, which together with the at its Sections of inner insulating mats with one end in a known manner on the tubular shaft, with the other end attached to the ceiling, is wound on the shaft in the rest position and rests in the operating position with the middle section on the floor. Developments of the invention are specified in the subclaims.

Einzelheiten, und Vorteile der Erfindung sind nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels des Gegenstandes der Erfindung näher erläutert.Details and advantages of the invention are explained below with reference to an embodiment of the subject matter of the invention shown in the drawing.

Show it:
  • 1 shows a longitudinal section through a closed fire protection roller door according to the invention,
  • 2 is a sectional view taken along the line BC in Fig. 1,
  • 3 shows a detail from FIG. 1,
  • 4 shows a section through a half-open roller door,
  • 5 is a sectional view taken along the line BC in Fig. 4,
  • Fig. 6, the attachment of the slats and the mats on the tubular shaft, and
  • Fig. 7 the attachment of the slats and the mats on the ceiling.

Bei dem dargestellten Feuerschutzrolltor handelt es sich um eine Einwellenanlage mit einem an einer Rohrwelle 7 und an der Decke 8 befestigten durchgehenden Panzer aus verzinkten, etwa 1 mm starken Stahlblechlamellen 1, an deren Längsrändern in an sich bekannter Weise die Gelenke in Form von ineinandergreifenden gekrümmten Streifen angeformt sind, mit innen eingelegten, nur an beiden Enden befestigten Matten 2 z.B. der Brandklasse A 1 in 40 mm Stärke.The fire protection roller shutter shown is a single-shaft system with a continuous armor attached to a tubular shaft 7 and to the ceiling 8, made of galvanized, approximately 1 mm thick steel sheet lamellae 1, on the longitudinal edges of which the joints in the form of interlocking curved strips in a manner known per se are integrally formed with mats 2 inserted on the inside and fastened only at both ends fire class A1 in 40 mm thickness.

Durch die auf diese Weise im geschlossenen Zustand (Betriebsstellung) erzielte Schlaufenbildung bilden sich zwei hereabhängende Panzerabschnitte 11 und 12, welche durch einen unteren Abschnitt 13 miteinander verbunden sind. Dieses untere Stück 13 wird durch z.B. eingenietete Bandstahlfedern 3 aus beispielsweise Federstahl 50/0,8 gerade gedrückt und preßt dadurch den lose gegen Anschläge 6 hängenden Panzerteil 12 an. Dieser Teil 12 ist ca. 30 mm überhängend bei 5 an der Decke 8 befestigt und wird dadurch auch im oberen Bereich angedrückt. Der an der Welle 7 hängende Teil 11 wird 70 mm breiter ausgeführt (je Seite 35 mm) und läuft beim Schließen automatisch in vorgesehene Führungsnuten 4, wobei er durch die Federn 3 ebenfalls nach außen gegen die Führungen 4 gedrückt wird.As a result of the loop formation thus achieved in the closed state (operating position), two hanging armor sections 11 and 12 are formed, which are connected to one another by a lower section 13. This lower piece 13 is e.g. riveted steel strip springs 3 made of spring steel 50 / 0.8, for example, are pressed straight and thereby presses the armored part 12 hanging loosely against stops 6. This part 12 is approximately 30 mm overhanging at 5 on the ceiling 8 and is thereby pressed in the upper area. The part 11 hanging on the shaft 7 is made 70 mm wider (35 mm on each side) and runs automatically in the provided guide grooves 4 when it is closed, whereby it is also pressed outwards against the guides 4 by the springs 3.

Die Stahlblechlamellen 1 der drei Panzerabschnitte 11, 12, 13 können in der gleichen Richtung gekrümmt von der Welle 7 bis zur Decke 8 verlaufen. Wie jedoch in Fig. 1 und 3 gezeigt, verlaufen die dargestellten Lamellen in den seitlichen Abschnitten 11 und 12 gegenläufig gekrümmt von der Welle 7 bzw. Decke 8 weg und treffen sich im mittleren Abschnitt 13, wo sie durch einen C-förmigen Verbinder 10 gelenkig miteinander verbunden sind.The steel sheet lamellae 1 of the three armor sections 11, 12, 13 can run curved in the same direction from the shaft 7 to the ceiling 8. However, as shown in FIGS. 1 and 3, the lamellae shown in the lateral sections 11 and 12 run in opposite directions from the shaft 7 or ceiling 8 and meet in the central section 13, where they are articulated by a C-shaped connector 10 are interconnected.

Die übliche Sturzschräge 16,17 kann aus Beton mit einer Gleitblechabdeckung oder direkt aus Blech angefertigt werden. Die seitlichen Führungen 4 bestehen aus abgekantetem 3 mm starken Stahlblech, können durch eine sickenförmige Abkantung ineinandergesteckt werden und werden nur durch eine vordere Andrückverschraubung gehalten.The usual camber 16, 17 can be made of concrete with a sliding plate cover or directly from sheet metal. The side guides 4 consist of folded 3 mm thick steel sheet, can be inserted into each other by a bead-shaped bend and are only held by a front pressure screw connection.

Die Fig. 6 und 7 lassen erkennen, wie die Lamellen der Abschnitte 11 bzw. 12 mit den Matten 2 and der Welle 7 bzw. Decke 8 befestigt sind. Während die Befestigung and der Decke 8 mittels Winkeleisen und Schrauben erfolgt, sind an der Welle 7 besondere Hänger 15 vorgesehen (vgl. auch Fig. 2).6 and 7 show how the slats of the sections 11 and 12 are attached to the mats 2 on the shaft 7 and ceiling 8. While the attachment to the ceiling 8 takes place by means of angle iron and screws, special hangers 15 are provided on the shaft 7 (cf. also FIG. 2).

Der Antrieb erfolgt gewöhnlich über Elektromotor.It is usually driven by an electric motor.

Ein Brandversuch mit einfacher Mattenfüllung für T 30 erbrachte 70 min Standfestigkeit (30 min gefordert) und mit an den seitlichen Panzerabschnitten 11 und 12 aufgedoppelter Matte für T 90 110 min Standfestigkeit (90 min gefordert). Selbstverständlich ist dieses neue Feuerschutzrolltor auch für T 120 und darüber geeignet. Dafür kommt es lediglich auf geeignete Wahl des Isolierabstandes 9 zwischen den herunterhängenden Abschnitten 11 und 12 sowie auf Dimensionierung und Materialauswahl für die Mattenfüllungen 2 an.A fire test with a simple mat filling for T 30 resulted in 70 min stability (30 min required) and with a mat doubled on the side armor sections 11 and 12 for T 90 110 min stability (90 min required). Of course this new fire protection roller door is also suitable for T 120 and above. All that is required is a suitable choice of the insulation spacing 9 between the hanging sections 11 and 12, as well as dimensioning and material selection for the mat fillings 2.
