Abstract

In this fire-proof shaft door, improved heat insulation towards the shaft side is achieved in the event of a fire on the floor side, as a result of which the elevator shaft in case of fire is retained as an escape route for the fire brigade. A door box (24) is arranged on the floor side on a frame (23) carried by a door suspension (14), made of profiled sheet and guided by a guide tongue (22). The door box (24) is filled with heat-insulating zones and heat-insulating mats. Horizontal ribs (28) provided with ventilation holes are arranged on the shaft side on the frame (23). On the shaft side, the ribs (28) carry heat-insulating boards (29) covering the front of the door. The first hollow space (30) formed by the heat-insulating boards (29) at a distance from the frame (23) acts as a natural chimney in which fresh air designated by A circulates. <IMAGE>

Description

Die Erfindung betrifft eine brandsichere Schachttür für Aufzugsanlagen, die mittels einer in einer Rollenführung geführten Rolle verschiebbar ist, an der eine einen Rahmen mit Wärmedämmstoffen tragende Aufhängung angreift und die im Fussbereich in einer in einer Schwelle eingelassenen Gleitführung geführt wird.The invention relates to a fire-proof shaft door for elevator systems, which is displaceable by means of a roller guided in a roller guide, on which a suspension bearing a frame engages with thermal insulation materials and which is guided in the foot area in a sliding guide embedded in a threshold.

Die Offenlegungsschrift DE-A1 25 12 536 offenbart eine kastenartige Fahrschachttür, bei der im unteren Bereich des schachtseitigen Türdeckbleches Kühlluftzufuhröffnungen und im oberen Bereich desselben Kühlluftabfuhröffnungen vorgesehen sind. Damit wird das flurseitige Türdeckblech gleichmässig gekühlt und das schachtseitige Türdeckblech vor zu starker Erwärmung geschützt.The published patent application DE-A1 25 12 536 discloses a box-like landing door in which cooling air supply openings are provided in the lower region of the shaft-side door cover plate and cooling air discharge openings are provided in the upper region of the same. This cools the corridor-side door cover plate evenly and protects the shaft-side door cover plate against excessive heating.

Die Offenlegungsschrift FR-A1 2 610 311 offenbart eine einen Rahmen aufweisende Fahrschachttür, der als Träger für je ein flur- und schachtseitig angeordnetes Isolierpanel dient. Der Rahmen selbst ist mit einer Isoliermatte gefüllt. Mit diesem Türaufbau wird eine Brandresistenz von zwei Stunden erreicht.The laid-open document FR-A1 2 610 311 discloses a landing shaft door which has a frame and serves as a support for an insulating panel arranged on the corridor and shaft side. The frame itself is filled with an insulating mat. With this door structure, a fire resistance of two hours is achieved.

Ein Nachteil der bekannten Einrichtungen liegt darin, dass sie den verschärften Vorschriften bestimmter Länder hinsichtlich Temperaturgefälle zwischen Brandseite und Kaltseite nicht genügen.A disadvantage of the known devices is that they do not meet the stricter regulations of certain countries with regard to temperature differences between the fire side and the cold side.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, die Nachteile der bekannten Einrichtungen zu vermeiden und eine brandsichere Schachttür zu schaffen, die den Anforderungen an Stabilität, Brandresistenz und Wärmedämmung gerecht wird.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of avoiding the disadvantages of the known devices and of creating a fire-proof shaft door that meets the requirements for stability, fire resistance and thermal insulation.

Der durch die Erfindung erreichte Vorteil ist im wesentlichen darin zu sehen, dass bei flurseitigem Feuer dank der verbesserten Wärmedämmung zur Schachtseite hin der Aufzugsschacht der Feuerwehr als Fluchtweg erhalten bleibt. Ein weiterer Vorteil ist darin zu sehen, dass trotz verbesserten Brandschutzeigenschaften das Gesamtgewicht der Schachttür klein gehalten werden kann. Ein weiterer Vorteil ist darin zu sehen, dass Wärmebrücken zwischen den Wärmedämmschichten weitgehend vermieden werden können. Ein weiterer Vorteil besteht darin, dass die üblicherweise notwendigen Brandschutzschleusen vor den Aufzugstüren auf jedem Stockwerk unnötig werden.The advantage achieved by the invention can essentially be seen in the fact that, in the case of fire on the corridor, the lift shaft of the fire service is retained as an escape route thanks to the improved thermal insulation on the shaft side. Another advantage is that despite the improved fire protection properties, the overall weight of the landing door can be kept small. Another advantage is that thermal bridges between the thermal insulation layers can be largely avoided. Another advantage is that the fire barriers that are usually required in front of the elevator doors on each floor are unnecessary.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigen:

Eine erfindungsgemässe Schachttür in einer vertikalen Querschnittsansicht und
Fig. 2
ein Stockwerk im Schachttürbereich in einer horizontalen Querschnittsansicht.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. Show it:
Fig. 1
A shaft door according to the invention in a vertical cross-sectional view and
Fig. 2
a floor in the shaft door area in a horizontal cross-sectional view.

In den Fig. 1 und 2 ist mit F ein Feuer und mit 1 ein Fußboden eines Flurs 2, bezeichnet, der oben im Schachttürbereich durch einen Türsturz 3 und seitlich durch Türpfosten 4 abgeschlossen ist. Türsturz 3 und Türpfosten 4 bilden eine Schachtöffnung eines Aufzugschachtes 5, die von einer hintergreifenden Türzarge 6 umfasst wird. Die mit Wärmedämmstoffen 7 gefüllte Türzarge 6 steht oben mittels einem horizontalen Abschluss 8 mit dem Türsturz 3 und je Seite mittels einem vertikalen Abschluss 9 mit dem Türpfosten 4 in Verbindung. Zum Ausgleich von baulichen und mechanischen Abweichungen ist zwischen Türzarge 6 und Türsturz 3 beziehungsweise zwischen Türzarge 6 und Türpfosten 4 ein wärmedämmender Dichtungswulst 10 vorgesehen. Der obere horizontale Türrahmenteil steht in Verbindung mit einer Befestigungsschiene 11 und endet schachtseitig mit einem eine Rollenführung 12 tragenden Querträger 13, an dem eine die Rollenführung 12 und Türaufhängung 14 mit Rolle 15 überspannende Abdeckung 16 mit Wärmedämmschicht angeordnet ist. Der untere horizontale Türrahmenteil endet schachtseitig mit einem einen Schwellenträger 17 abdeckenden Deckblech 18. In den Schwellenträger 17 ist eine Schwelle 19 mit einer Gleitführung 20 eingelassen, in der ein an einem Führungsträger 21 angeordnetes Führungsschwert 22 gleitet.1 and 2, F denotes a fire and 1 a floor of a hallway 2, which is closed at the top in the shaft door area by a lintel 3 and laterally by door jambs 4. Lintel 3 and door jamb 4 form a shaft opening of an elevator shaft 5, which is encompassed by an engaging door frame 6. The door frame 6 filled with thermal insulation materials 7 is connected at the top by means of a horizontal closure 8 to the lintel 3 and on each side by means of a vertical closure 9 to the door jamb 4. To compensate for structural and mechanical deviations between door frame 6 and lintel 3 or between door frame 6 and Door jamb 4 provided a heat-insulating sealing bead 10. The upper horizontal door frame part is connected to a fastening rail 11 and ends on the shaft side with a cross member 13 carrying a roller guide 12, on which a cover 16 with a thermal insulation layer spanning the roller guide 12 and door suspension 14 with roller 15 is arranged. The lower horizontal door frame part ends on the shaft side with a cover plate 18 covering a sleeper support 17. A sleeper 19 with a slide guide 20 is embedded in the sleeper support 17, in which a guide sword 22 arranged on a guide bracket 21 slides.

An einem von der Türaufhängung 14 getragenen, aus Profilblech bestehenden und vom Führungsschwert 22 geführten Rahmen 23 ist flur- oder feuerseitig ein Türkasten 24 angeordnet, der wie in Fig. 2 dargestellt mit Wärmedämmfeldern 25 und Wärmedämmmatten 26 in der flurseitig beginnenden Schichtungsreihenfolge Wärmedämmfeld 25, Wärmedämmmatte 26, Wärmedämmfeld 25, Wärmedämmmatte 26 gefüllt ist. Schachtseitig sind am Rahmen 23 horizontale mit Lüftungslöchern 27 versehene Spanten 28 angeordnet, die schachtseitig die Türfront überdeckende Wärmedämmplatten 29 tragen. In einer weiteren Ausführungsvariante sind die Spanten 28 vertikal angeordnet. Der durch die vom Rahmen 23 beabstandeten Wärmedämmplatten 29 gebildete erste Hohlraum 30 wirkt als natürlicher Kamin, in dem mit A bezeichnete Frischluft zirkuliert. Der Türkasten 24 weist an der Schliesskante einen Rücksprung 31 auf, so dass bei geschlossenen Türen ein zweiter Hohlraum 32 mit Kaminwirkung entsteht, der der Wärmedämmung im Schliessbereich dient.On a frame 23 carried by the door suspension 14, consisting of profiled sheet metal and guided by the guiding sword 22, a door box 24 is arranged on the hall or fire side, which, as shown in FIG 26, thermal insulation field 25, thermal insulation mat 26 is filled. On the shaft side, horizontal frames 28 provided with ventilation holes 27 are arranged on the frame, which support thermal insulation panels 29 covering the door front on the shaft side. In a further embodiment variant, the frames 28 are arranged vertically. The first cavity 30 formed by the thermal insulation panels 29 spaced apart from the frame 23 acts as a natural chimney in which fresh air labeled A circulates. The door box 24 has a recess 31 on the closing edge, so that when the doors are closed, a second cavity 32 with a chimney effect is created, which is used for thermal insulation in the closing area.
