Description

Die Erfindung betrifft einen Sprinkler für selbsttätige Feuerlöschanlagen nach dem Trockensystem für frostgefährdete Räume oder dergleichen, mit von Gewindestutzen der Löschmittelleitung der Anlage nach unten abzweigenden Rohrstücken, die am oberen Ende eine Dichtung aufweisen und die am unteren Ende den Sprinkler tragen, in deren Bereich sich eine, nur den Sprinkler sichtbar machende, abgehängte Decke befindet.The invention relates to a sprinkler for automatic fire extinguishing systems according to the drying system for rooms at risk of frost or the like, with pieces of pipe branching down from the threaded connection of the extinguishing agent line of the system, which have a seal at the upper end and which carry the sprinkler at the lower end, in the area of which there is one , only the suspended ceiling that makes the sprinkler visible.

Derartige Sprinkler werden im wesentlichen nicht nur in frostgefährdeten Räumen eingesetzt (DE-OS 17 08 090). Sie werden auch unter den abgehängten Decken in Verkaufsräumen in Kaufhäusern oder dergleichen (DE-GM 89 09 716) eingesetzt, wenn der Raum oberhalb der abgehängten Decke frostgefährdet ist. In diesem Fall ist ein oberer Abschluß der Rohrstücke vorzusehen. Bei der Sprinkleranlage nach der DE-OS 17 08 090 ist der obere Abschluß als Membran ausgebildet, deren Haltbarkeit nur sehr begrenzt ist.Such sprinklers are essentially not only used in rooms where there is a risk of frost (DE-OS 17 08 090). They are also used under the suspended ceilings in sales rooms in department stores or the like (DE-GM 89 09 716) if the space above the suspended ceiling is at risk of frost. In this case, an upper end of the pipe sections must be provided. In the sprinkler system according to DE-OS 17 08 090, the upper end is designed as a membrane, the durability of which is very limited.

Der obere Abschluß ist erforderlich, damit nach dem Entleeren der Anlage kein Restwasser in dem Rohrstück verbleibt.The upper end is necessary so that no residual water remains in the pipe section after the system has been emptied.

Beim Gegenstand nach dem DE-GM 89 09 716 sind die Sprinkler über ein flexibles Schlauchstück an die Löschmittelleitung angeschlossen. Eine gesonderte Aufhängungsvorrichtung ist einerseits längenveränderlich mit der Raumdecke und andererseits mit dem Sprinkler verbunden. Die Schlauchstücke müssen laut Vorschrift bis 10 bar druckdicht sein. Diese druckfesten Schläuche sind zwar biegsam, können aber keine Druck- bzw. Zugkräfte aufnehmen. Dies bedeutet, daß bei veränderlichen Abständen der abgehängten Decke von der Raumdecke, die Länge des Schlauches dem Abstand angepaßt werden muß. Dies führt bei der Montage auf der Baustelle zu Schwierigkeiten.In the case of the object according to DE-GM 89 09 716, the sprinklers are connected to the extinguishing agent line via a flexible hose section. A separate suspension device is connected on the one hand variable in length to the ceiling and on the other hand to the sprinkler. The hose pieces must be up to 10 bar according to the regulations be pressure tight. These pressure-resistant hoses are flexible, but cannot absorb pressure or tensile forces. This means that with variable distances between the suspended ceiling and the ceiling, the length of the hose must be adapted to the distance. This leads to difficulties when assembling on the construction site.

Die abgehängten Decken sind zur Raumdecke des Gebäudes aufgrund baulicher Gegebenheiten mit Toleranzen von 2 bis 5 cm angebracht. Fernerhin ist das Rohrnetz für die Löschmittelleitungen mit Gefälle verlegt, damit das Rohrnetz im Bedarfsfalle entwässert werden kann.The suspended ceilings are attached to the room ceiling of the building due to structural conditions with tolerances of 2 to 5 cm. Furthermore, the pipe network for the extinguishing agent lines is laid with a slope so that the pipe network can be drained if necessary.

Zur Folge dieser beiden letztgenannten Maßnahmen müssen die die Sprinkler tragenden Rohrstücke an den Einbaustellen mit unterschiedlichen Längenmaßen eingebaut werden, was bedeutet, daß die nach unten führenden Rohrstücke mit unterschiedlichen Längen auf der Baustelle hergestellt werden müssen, damit sie den baulichen Gegebenheiten angepaßt sind. Oder aber, die Rohrstücke müssen in der Werkstatt des Herstellers nach Angaben des Monteurs hergestellt werden.As a consequence of these two latter measures, the pipe sections carrying the sprinklers must be installed at the installation sites with different lengths, which means that the pipe sections leading downward must be manufactured with different lengths on the construction site so that they are adapted to the structural conditions. Or else, the pipe sections must be manufactured in the manufacturer's workshop according to the installer's instructions.

Sowohl der Baustellen- als auch die Werkstätten-Anpassung der Rohrstücke sind zeit- und kostenaufwendig.Both the construction site and the workshop adaptation of the pipe sections are time-consuming and costly.

Der Erfindung liegt die Aufgabe zugrunde einen an Rohrstücken hängenden Sprinkler für abgehängte Decken in frostgefährdeten Räumen zu schaffen, der mit die durch bauliche Maßnahmen gegebenen Toleranzen und die aufgrund des Gefälles der Löschmittelleitung gegebenen Differenzen zur abgehängten Decke ohne Baustellen- oder Werkstätten-Anpassung ausgleicht, und somit eine Vorratsfertigung derartiger Sprinkler mit Rohrstücken ermöglicht.The invention has for its object a piece of pipe to create hanging sprinklers for suspended ceilings in rooms at risk of frost, which compensates with the tolerances given by structural measures and the differences due to the gradient of the extinguishing agent line to the suspended ceiling without having to adapt to construction sites or workshops, thus enabling the production of such sprinklers with pipe sections.

Diese Aufgabe wird dadurch gelöst, daß die Rohrstücke aus einem mittels Gewinde verschraubten zweiteiligen oberen und unteren Rohr bestehen, daß der Sprinkler mit dem Sprinklerkörper in das unteren Ende des unteren Rohres eingeschraubt ist, und daß der das Auslöseglied arretierende Sprinklerstutzen mit einem Rohr oder einer Stange verbunden ist, die mit einem weiteren Rohr oder Stange verschraubt ist, die am oberen Ende mit einem Stütz-körper versehen ist, der gegen einen mit dem Rohr verbundenen, einen Ventilsitz bildenen Stutzen andrückbar ist, daß die die beiden Rohre und die beiden Stangen verbindenen Gewinde mit gleichen Gewindesteigungen ausgebildet sind.This object is achieved in that the pipe sections consist of a threaded two-part upper and lower pipe, that the sprinkler with the sprinkler body is screwed into the lower end of the lower pipe, and that the sprinkler connector arresting the release member with a pipe or a rod is connected, which is screwed to a further tube or rod, which is provided at the upper end with a support body which can be pressed against a connecting piece connected to the tube, forming a valve seat, that the connecting the two tubes and the two rods Threads with the same thread pitches are formed.

Mit dieser Maßnahme lassen sich die baulichen Toleranzen und die Höhenunterschiede während der Montage ohne Schwierigkeiten ausgleichen. Ein besonderer Vorteil ist darin zu sehen, daß der werkstattmäßig hergestellte Sprinkler mit den geteilten Rohrstücken in den Gewindestutzen der Löschmittel-Leitung eingesetzt und sodann aufgrund der gleichen Gewindesteigungen in beiden Teilen gleichzeitig soweit verstellt werden kann, bis die gewünschte Höhe erreicht ist. Hierzu müssen die äußeren Rohre und die inneren Stangen jeweils drehfest miteinander verbunden sein. Zur Abdichtung der Löschmittelleitung gegenüber dem abzweigenden Rohrstück ist zwischen dem, den Ventilsitz bildenden oberen Stutzen und dem Stützkörper eine Dichtung vorgesehen.With this measure, the structural tolerances and the height differences during assembly can be compensated for without difficulty. A particular advantage can be seen in the fact that the sprinkler manufactured in the workshop with the divided pipe pieces is inserted into the threaded connector of the extinguishing agent line and then because of the same thread pitches in both parts can be adjusted at the same time until the desired height is reached. For this purpose, the outer tubes and the inner rods must be connected to one another in a rotationally fixed manner. To seal the extinguishing agent line from the branching pipe section, a seal is provided between the upper socket forming the valve seat and the support body.

Weitere Einzelheiten der Erfindung sind in einer Zeichnung dargestellt und werden nachfolgend näher beschrieben.Further details of the invention are shown in a drawing and are described in more detail below.
