Description
Druckstab aus einem Stahlrohrmantel und einem Kern aus Beton Man hat bereits stabförmige Bauteile aus einem mit Beton oder einem ähnlichen Baustoff gefüllten Stahlrohr verwendet. Setzt man diese Stäbe einem Längsdruck aus, so verteilt sich ihre Gesamtbeanspruchung auf den Stahlmantel und den Betonkern im Verhältnis ihrer Ouerschnitte und Elastizitätskoeffizienten. Da der Elastizitätskoeffizient des ummantelten Betons ungefähr % desjenigen des Stahles ist, beträgt, wenn der Stahl bis zu seiner Sicherheitsgrenze beansprucht wird, in der Regel die Beanspruchung des Betons nur einen geringen Bruchteil der für ihn zulässigen Belastung.Compression rod made of a tubular steel jacket and a core made of concrete already rod-shaped components made of one filled with concrete or a similar building material Steel pipe used. If these rods are subjected to longitudinal pressure, they distribute themselves their total stress on the steel jacket and the concrete core in relation to their Cross sections and coefficients of elasticity. As the coefficient of elasticity of the sheathed Concrete is about% that of steel, when the steel is up to its The safety limit is stressed, usually the stress on the concrete only a small fraction of the load that is permissible for him.
Die Erfindung verfolgt den Zweck, die Widerstandsfähigkeit eines solchen Stabes gegen Längsdruck erheblich zu vergrößern. Zu diesem Zwecke wird der Stahlmantel durch einen Längszug einer elastischen Vorspannung im Sinne einer Dehnung unterworfen. Dabei wird der entsprechende Gegendruck mittels an den Enden des Rohres angeordneter Spannvorrichtungen, wie Schraub-Stöpsel, von dem abgebundenen Betonkern aufgenommen und das gegenseitige Anhaften des Mantels und Kernes durch einen auf die Innenfläche des Rohres aufgebrachten nachgiebigen Überzug verhindert.The invention has the purpose of improving the resistance of such To enlarge the rod considerably against longitudinal pressure. For this purpose, the steel jacket subjected to elastic pretensioning in the sense of elongation by a longitudinal pull. In doing so, the corresponding counter pressure is arranged at the ends of the pipe Tensioning devices, such as screw plugs, taken up by the set concrete core and the cladding and core adhering to each other by one on the inner surface The flexible coating applied to the pipe is prevented.
Infolge dieser elastischen Vordehnung des Mantels kann man den Betonkern im Verhältnis zum Mantel höher belasten; nämlich um den Druck, den. er aufnimmt, während der Mantel wieder auf seine normale Länge und die Belastung Null zurückgeht.As a result of this elastic pre-stretching of the jacket, the concrete core can be removed load higher in relation to the coat; namely about the pressure that. he records while the jacket returns to its normal length and zero stress.
Die Zeichnung veranschaulicht die Erfindung an zwei Ausführungsbeispielen.The drawing illustrates the invention using two exemplary embodiments.
Abb. r ist ein Längsschnitt durch ein gefülltes Rohr mit an den Enden eingesetzten Schraubstöpseln.Fig.r is a longitudinal section through a filled tube with at the ends inserted screw plugs.
Abb. 2 zeigt ein aus drei Bogenstücken bestehendes Ringrohr und Abb.3 einen Schnitt durch eine Verbindungsstelle dieses Ringrohres.Fig. 2 shows an annular pipe consisting of three bends and Fig.3 a section through a junction of this ring tube.
Die Innenwand des Stahlrohres i (Abb. i) ist mit einem Schmiermittelüberzug 2 versehen, der das Anhaften des Betonkernes 3 an der Rohrwand verhindert. Das eine Ende des Rohres i ist durch einen vollen Gewindestöpsel 4 verschlossen, das andere Ende durch einen Gewindestöpsel 5 mit Einspritzkanal 6. Innerhalb der Stöpsel sind Scheiben 7 und 8 eingesetzt, von denen letztere mit einem mittleren Loch entsprechend dem Kanal 6 des Stöpsels 5 versehen ist. Die Scheiben 7 und 8 erleichtern das Einschrauben der Stöpsel, da sie das Eintreten von Füllstoff in das Gewinde verhindern. Die Scheiben kommen in Fortfall, wenn das Rohr mit einem pulverförmigen Stoff gefüllt wird.The inner wall of the steel pipe i (Fig. I) is coated with a lubricant 2, which prevents the concrete core 3 from sticking to the pipe wall. The one The end of the tube i is closed by a full threaded plug 4, the other End through a threaded plug 5 with injection channel 6. Inside the plug Discs 7 and 8 are used, the latter with a central hole accordingly the channel 6 of the plug 5 is provided. The washers 7 and 8 make it easier to screw in the plug as they prevent filler from entering the thread. The disks do not apply if the tube is filled with a powdery substance.
Der geschlossene Ring gemäß Abb. 2 ist im wesentlichen als waagerechte Bewehrung für Schachtauskleidungen gedacht. Er besteht aus drei Rohrbögen 9, io und i i, die durch Schraubmuffen i2, 13, 14 mit Rechts- und Linksgewinde vereinigt sind. jede dieser Muffen ist mit einem Einspritzloch 15 (Abb. 3) versehen. Durch Anziehen der Schraubmuffen wird das Stahlrohr unter Zugspannung und der Kern unter Druckspannung gesetzt.The closed ring according to Fig. 2 is essentially horizontal Reinforcement intended for manhole linings. It consists of three pipe bends 9, io and i i, which are united by screw sockets i2, 13, 14 with right-hand and left-hand threads are. each of these sleeves is provided with an injection hole 15 (Fig. 3). By Tightening the screw sockets puts the steel pipe under tension and the core under Compressive stress set.
