Description
Die Erfindung bezieht sich auf einen geschweißten Mehrlagenbehälter, bei dem die Schweißnähte jeweils benachbarte Bleche derselben Lage miteinander und mit der von dieser umschlossenen Lage verbinden. The invention relates to a welded multi-layer container, in which the weld seams in each case adjacent sheets of the same position with each other and connect with the position enclosed by this.
Derartige Behälter sind besonders als sehr hohen Drücken ausgesetzte Großbehälter bekannt. Dabei werden die einzelnen Blechlagen so angeordnet, daß die Stoßfugen in benachbarten Lagen gegeneinander versetzt sind, so daß die Schweißnähte an den Stoßstellen jeweils drei Bleche miteinander verbinden. Such containers are particularly exposed to very high pressures Large container known. The individual sheet metal layers are arranged so that the Butt joints in adjacent layers are offset from one another, so that the welds Connect three sheets to each other at the joints.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Mehrlagenbehälter der eingangs genannten Bauart die Gefahr zu beseitigen, daß solche sogenannten Dreiblech-Schweißnähte durch zu hohe Schubbeanspruchungen zerstört werden. Derartige Schubbeanspruchungen können dann auftreten, wenn infolge eines Blechrisses od. dgl. in einem Lagenblech die von diesem normalerweise aufzunehmende Zugbeanspruchung durch die ! Schweißnähte in die benachbarten Lagen übertragen wird. The invention is based on the object of a multi-layer container the type mentioned to eliminate the risk that such so-called three-sheet welds can be destroyed by excessive shear loads. Such shear stresses can occur if as a result of a sheet metal crack or the like in a sheet metal the tensile stress normally to be absorbed by the! Welds is transferred to the neighboring layers.
Die genannte Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Breite der Schweißnaht an ihrer Verbindungsstelle mit der umschlossenen Lage mindestens das 1,75fach der Dicke der einzelnen Lagen beträgt. The stated object is achieved according to the invention in that the Width of the weld seam at its connection point with the enclosed layer at least 1.75 times the thickness of the individual layers.
Da nach den Regeln der Festigkeitslehre für elastische Werkstoffe die größte zulässige Zugspannung das 3 = 1,73fache der größten zulässigen Schubspannung beträgt, ergibt sich daraus für die erfindungsgemäße Schweißnaht, daß dort die zulässigen Spannungswerte bei normaler Zugbeanspruchung durch den im Behälter herrschenden Innendruck und bei eventuell auftretender Schubbeanspruchung im 'giCenVerhältnis liegen, d-.--h.; diè Schweißnaht hält mit der Zugbeanspruchung auch die eventuelle Schubbeanspruchung aus. Because according to the rules of strength theory for elastic materials the greatest permissible tensile stress is 3 = 1.73 times the greatest permissible shear stress is, it follows for the weld seam according to the invention that there the permissible Stress values for normal tensile stress due to the prevailing in the container Internal pressure and any shear stress in the 'giCen ratio lie, d -.-- h .; The weld seam holds with the tensile stress also the eventual one Shear stress.
Zweckmäßig wird bei der Herstellung der breiten Schweißnähte des Mehrlagenbehälters so verfahren, daß zunächst der gewünschte Mindestabstand der benachbarten Bleche in den einzelnen Lagen durch Einbringen von Abstandsstücken erzeugt wird und sodann zwischen diesen die Herstellung der Schweißnähte begonnen und nach Entfernen der Abstandsstücke vervollständigt wird. It is useful when producing the wide weld seams Proceed with the multi-layer container so that that first the desired minimum distance of the neighboring Sheet metal in the individual layers is produced by introducing spacers and then the production of the weld seams started between these and after removal the spacers is completed.
Die Zeichnung zeigt als Ausführungsbeispiel der Erfindung einen Teilschnitt durch zwei benachbarte Lagen eines Mehrlagenbehälters mit einer »Dreiblech-Schweißnaht«. Über dem Blech 1 der inneren Lage sind die beiden benachbarten Bleche 2 und 3 der diese umschließende Lage angeordnet, die durch die Schweißnaht 4 miteinander und mit dem Blech 1 der inneren Lage verbunden sind. Dabei ist gemäß der Erfindung die Breite b der Schweißnaht an ihrer Wurzel, d. h. der Verbindungsstelle mit dem Blech 1, so groß gewählt worden, daß sie das 1,75fache der Dicke d des Bleches 1 beträgt. As an embodiment of the invention, the drawing shows a partial section through two adjacent layers of a multi-layer container with a »three-sheet weld seam«. Above the sheet 1 of the inner layer, the two adjacent sheets 2 and 3 are the arranged this enclosing layer, which by the weld 4 to each other and are connected to the sheet 1 of the inner layer. It is according to the invention Width b of the weld seam at its root, d. H. the connection point with the sheet metal 1, has been chosen so large that it is 1.75 times the thickness d of the sheet 1.
