Description
Stützkörper mit Betc,#kern- und Eisenrohnnantel Die Erfindung betrifft in axialer Richtung auf Druck beanspruchte stabförmige Bauteile, bestehend aus einem Betonkern mit Eisen- oder Stahlrohrummantelung. Im be- sonderen bezieht sich die Erfindung auf solche Baukörper, :die, -wie z. B. Grubenstempel, solche Abmessungen haben, daß die Möglichkeitdes Auftretens von Blegungsspannungen und damit die Knickgefahr ausgeschlossen ist.Support body with Betc, # kern- and Eisenrohnnantel The invention relates to rod-shaped components which are subjected to pressure in the axial direction and which consist of a concrete core with an iron or steel tube casing. In particular In the invention relates to such structure: which, for -As. B. pit punches, have such dimensions that the possibility of the occurrence of laying stresses and thus the risk of buckling is excluded.
Die Ausführung der der Erfindung zugrunde liegenden Aufgabe erfolgt in der durch die Zeichnung an einem Ausführungsbeispiel erläuterten Art und Weise. Der Stützkörper ist,dort in Abb. i in Ansicht und te-äweis-ern Längsschnitt, in Abb.? in Oberansieht dargestellt.The object on which the invention is based is carried out in the manner explained by the drawing using an exemplary embodiment. The support body is shown there in Fig Fig. shown in top view.
Der Betonkerna ist in neuartiger Weis-enicht von einem !durchgehenden Eisen- oder Stahlrohr umschlossen, sondern von einzelnen Rohrschüssenb oder zusammengeschweißten Hülsen, die in entsprechenden Abständen c übereinanderliegen.In a new way, the Betonkerna is not of a continuous one Iron or steel pipe enclosed, but by individual pipe sectionsb or welded together Sleeves that are superimposed at corresponding distances c.
Dadurch wird erzielt, daß der Stützdruck zunächst vom Betonkerna allein aufgenommen wird und sich infolge Ader hierbei entstehenden Querdehnung des Kernes erst mittelbar als radial nach außen wirkende Kraft auf die Rohrschüsse oder Hälseub auswirkt.This ensures that the support pressure is initially from the concrete core alone is absorbed and as a result of the vein resulting transverse expansion of the core only indirectly as a force acting radially outwards on the pipe sections or necks affects.
Die ;so auf diese Teile einwirkende Kraft setzt sich in diesen in Ringzugspannungen um#- während bei iden bekannten Stätzkörperxi mit durchgehender RohrummanteluTig letztere in axialer Richtung belastet und beansprucht wird, wobei in der Regel der auf Stauchung beanspruchte Rohrmantel den Hauptteil der Belastung, der Betonkern dagegen nur einen geringen Teil davon zu tragen hat. Um beim Erfindungsgegenstande das den Betonkern umschließende Eisen infolge der auftretenden Ringzugspannungen bis zur Fließgrenze zu beanspruchen, ist aber ein Mehrfaches der Kraft erforderlich, die das gleiche Eisen bei axialer Beanspruchung in FUeßzustand bringt. Mithin ergibt sieh für den Stätzkörper der Erfindung eine bedeutend höhere Belastungsfähigkeit, als sie den bekannten Stützkörpern dieser Art zukommt.The force acting on these parts is in them Ring tensile stresses around # - while with iden known Stätzkörperxi with continuous RohrummanteluTig the latter is loaded and stressed in the axial direction, whereby As a rule, the pipe jacket subjected to compression is the main part of the load, the concrete core, on the other hand, only has to bear a small part of it. To the subject matter of the invention the iron surrounding the concrete core as a result of the ring tensile stresses that occur to stress up to the yield point, but a multiple of the force is required, which brings the same iron to its feet when subjected to axial stress. So it results see a significantly higher load capacity for the support body of the invention, than it belongs to the known support bodies of this type.
