Abstract
Description
Die vorliegende Erfindung betrifft eine Überdrucklüftungsanlage für Feuerwehraufzugsvorräume in Hochhäusern zur Verhinderung des Eindringens von Feuer, Rauch oder anderen Gasen in den Fahrschacht und die Vorräume. Musterhochhausrichtlinien und Bauordnungen verlangen bei einem Maß von mehr als 30m zwischen Geländeoberfläche und dem Fußboden eines Aufenthaltsraumes Feuerwehraufzüge. Diese Aufzüge stehen der Feuerwehr im Brandfall für den Löschangriff zur Verfügung.The present invention relates to an overpressure ventilation system for fire brigade lifts in high-rise buildings Prevents fire, smoke or other gases from entering in the elevator shaft and the vestibules. Sample high-rise building guidelines and building regulations require a measure of more than 30m between the surface of the site and the floor fire brigade of a common room. These elevators are standing the fire brigade in the event of a fire the fire attack to disposal.
Feuerwehraufzüge befinden sich in einem Fahrschacht aus nichtbrennbaren Baustoffen mit feuerbeständigen Wänden.Fire service lifts are located in a lift shaft made of non-combustible building materials with fire-resistant walls.
Die Feuerwehraufzüge müssen Vorräume mit Hydrantenanschlüssen haben. Diese Vorräume stehen über feuerhemmende, selbstschließende Türen in Verbindung mit den möglichen Brandabschnitten. Die Vorräume dienen der Feuerwehr zur Vorbereitung auf den Löschangriff und als Rückzugsmöglichkeit im Gefahrenfalle sowie zur Rettung von Personen. Der Aufzugsschacht und die Aufzugsvorräume müssen deshalb frei von Feuer, Rauch und anderen Gasen sein.The fire service lifts must have anterooms with hydrant connections. These vestibules are above fire retardant, self-closing Doors in Connect with the possible Fire zones. The vestibules are used by the fire brigade to prepare for the fire attack and as a retreat in the event of danger and to rescue people. The elevator shaft and the elevator lobbies have to therefore be free of fire, smoke and other gases.
Bisher wurde dies für die Vorräume erreicht, indem diese durch eine Lüftungsanlage mit Zu- und Abluft ver- und entsorgt wurden. Dabei war darauf zu achten, daß die Zuluftmenge etwas höher als die Abluftmenge gehalten wurde, um einen Überdruck im Feuerwehraufzugsvorraum aufrecht zu er halten. Dieser Überdruck soll gegenüber der Atmosphäre einen vorgegebenen Maximaldruck von 50 Pa nicht überschreiten, damit sich zur Brandbekämpfung und zur Personenrettung die Türen noch öffnen lassen; Feuer, Rauch und Gase jedoch nicht eindringen können.So far this has been achieved for the vestibules by this through a ventilation system were supplied and disposed of with supply and exhaust air. It was important to ensure that the Supply air volume somewhat higher when the amount of exhaust air was held to an overpressure in the fire brigade lobby to keep upright. This overpressure should be opposite the atmosphere do not exceed a specified maximum pressure of 50 Pa, so that the Firefighting and the doors to rescue people still open to let; However, fire, smoke and gases cannot penetrate.
Die Zu- und Abluftführung erfolgt über Schächte, die je Geschoß Schachtquerschnitte von bis zu 4m2 beanspruchen. Der Flächenverlust bedeutet einen Nutzungsverlust im Hochhaus.The supply and exhaust air routing takes place via shafts that take up shaft cross sections of up to 4m 2 on each floor. The loss of space means a loss of use in the high-rise.
Darüber hinaus kann mit dieser Konzeption nicht gewährleistet werden, daß kein Rauch in den Aufzugsschacht gelangt, da dieser nicht raumlufttechnisch behandelt wird.In addition, with this Concept not guaranteed be that no Smoke gets into the elevator shaft because it is not ventilation technology is treated.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Überdrucklüftungsanlage zu schaffen, die das Eindringen von Feuer, Rauch und anderen Gasen in den Aufzugsschacht und die Aufzugsvorräume verhindert. Weiterhin soll erreicht werden, daß die Flächen, die für die Lüftungsschächte erforderlich sind, als Nutzflächen zur Verfügung stehen.The present invention lies therefore based on the task of creating a pressurized ventilation system that the penetration of fire, smoke and other gases into the elevator shaft and the elevator lobbies prevented. Furthermore, it should be achieved that the surfaces that are required for the ventilation shafts as acreages to disposal stand.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine Unterdruckkammer und ein Ventilator, eine Überdruck-Sicherheitsklappe und ein Zuluftkanal so angeordnet sind, daß sie mit dem Aufzugsschacht direkt in Verbindung stehen und einen Zuluftstrom in den Aufzugsschacht einblasen.The object is achieved in that a vacuum chamber and a fan, an overpressure safety flap and an air intake duct are arranged so that they are connected to the elevator shaft are directly connected and a supply air flow into the elevator shaft blow.
Darüber hinaus sind zwischen dem Aufzugsschacht und dem Aufzugsvorraum Überströmklappen installiert, die es ermöglichen, daß Zuluft in die Aufzugsvorräume gelangen kann.In addition, between the Elevator shaft and the elevator vestibule installed overflow flaps there enable, that supply air into the elevator lobbies can reach.
