Vorliegende Erfindung bezweckt, jjiserne ■ Constructionstheile, namentlich solche aus Gul'seisen hergestellte, als Säulen, Träger u. s. w., dadurch gegen das Feuer widerstandsfähig zu machen, dafs in das Innere dieser Theile eine die Kühlung derselben bewirkende Flüssigkeit eingelassen wird, welche, unten eintretend, aufwärts steigt und nahezu am höchsten Punkte der Säule u. s. w. abfiiefst. .The present invention aims to jjiserne Construction parts, especially those made of gulden iron manufactured as pillars, girders, etc., thereby becoming resistant to fire make that in the interior of these parts there is a liquid which cools them which, entering below, rises upwards and almost at the highest point the column and so on. . In beiliegender Zeichnung ist die Erfindung an einer Säule dargestellt, von welcher Fig. 1 den unteren Theil und Fig. 2 den· oberen zeigt. Fig. 3 ist Gesammtdarstellung in kleinerem Mafsstabe als Fig. rund 2. Fig. 4 ist Querschnitt durch einen seitlichen Träger.In the accompanying drawing, the invention is shown on a column, of which FIG. 1 the lower part and FIG. 2 the upper part. Fig. 3 is an overall representation on a smaller scale Scale as Fig. Around 2. Fig. 4 is a cross section through a side support. In den unteren Theil der Säule α mündet ein Druckwasser oder eine sonstige unter Druck stehende Kühlflüssigkeit . zuführendes Rohr b, während ein bis zum höchsten Theile der Säule hinaufgeführtes, oben offenes Rohr c im Innern derselben zur Ableitung der Flüssigkeit dient. Die Säule ist über das Dach hinausgeführt und oben offen, um den sich ent-, wickelnden Dämpfen Abzug zu verschaffen. Die Leitungen b und c können nach Erfordernifs für mehrere Säulen unter einander verbunden sein. -■·..'·.Pressurized water or some other pressurized cooling liquid flows into the lower part of the column α. feeding tube b, while a tube c , open at the top, which extends up to the highest part of the column, serves to drain off the liquid inside the column. The column is led out over the roof and open at the top to allow the evolving vapors to be extracted. The lines b and c can be connected to each other as required for several columns. - ■ · .. '·. Aus Fig. 2 ist ersichtlich, in welcher Weise der Anschluss der Kastenträger an die Säule ausgeführt werden. könnte, um auch in diese Kühlflüssigkeit einzulassen. Um der Temperaturausdehnung Rechnung zu tragen, ist hier der eine Träger e1 (in der Zeichnung links) nicht direct· mit dem Hohlraum der Säule α verbunden, sondern empfängt die Flüssigkeit durch ein Rohr f aus dem Träger e. From Fig. 2 it can be seen in which way the connection of the box girders to the column is carried out. could to let in this coolant too. In order to take into account the temperature expansion, the one support e 1 (left in the drawing) is not directly connected to the cavity of the column α , but receives the liquid through a tube f from the support e. Bei ausbrechender Feuersbrunst werden die mit Hydranten oder Spritzen in Verbindung stehenden Zuleitungsrohre b geöffnet, die Kühlflüssigkeit steigt im Innern der Säule in die Höhe und fliefst durch die Rohre c wieder ab.When a fire breaks out, the supply pipes b connected to hydrants or syringes are opened, the cooling liquid rises inside the column and flows off again through pipes c . Aus dem Innern der Säule gelangt die Flüssigkeit auch in die Abzweigungen der Träger u. s. w. und schützt auch diese gegen Erhitzung. Die sich ■ entwickelnden Dämpfe entweichen durch die obere Oeffnung der Säule. Die Anordnung des Zuführungsrohres am unteren Ende der Säule ermöglicht, dieselbe leicht zu entleeren, um das Rosten von innen aus zu' verhüten. . ■From inside the column, the liquid also reaches the branches of the supports and so on and also protects them against overheating. The ■ developing vapors escape through the upper opening of the column. The arrangement of the supply pipe at the bottom End of the column allows it to be easily emptied to prevent rusting from inside prevent. . ■ Patent-Anspruch:Patent claim: Eine Einrichtung zum Schütze eiserner hohler Säulen, Stützen und dergleichen im Falle eines Brandes, dadurch gekennzeichnet, dafs eine unter Druck stehende Kühlflüssigkeit am Fufse der zu schützenden Säule u. s. w. durch ein Rohr (b) eingeführt wird, den Hohlraum derselben, sowie den der etwa angeschlossenen Constructionstheile durchströmt, um dann durch ein im Innern der Säule hochgeführtes und im oberen Theile derselben mündendes Rohr (c) wieder abzufliefsen. .,.-:■A device for protecting iron hollow columns, supports and the like in the event of a fire, characterized in that a pressurized cooling liquid is introduced at the foot of the column to be protected, etc. through a pipe (b) , the cavity of the same and that of the possibly connected It flows through parts of the construction, and then drains off again through a pipe (c) raised inside the column and opening into the upper part of the same. ., .-: ■ Hierzu ι Blatt Zeichnungen.For this purpose ι sheet of drawings.
