Durch wechselständige Aneinanderreihung metallener Spundwandtafeln aus trogförmigen Walzprofilen mit an den Profilschenkeln angenieteten Verbindungsleisten hat man versucht, Spundwände von besonders großem Widerstandsmoment herzustellen.By alternately lining up metal sheet piling panels made of trough-shaped Rolled profiles with connecting strips riveted to the profile legs have been tried to Manufacture sheet piling with a particularly high section modulus.

Im Gegensatz hierzu werden nach der vorliegenden Erfindung die Leisten der trogförmigen Spundwandtafeln so geformt, daß die Tafeln beim Aneinanderreihen alle mit ihrer Trogöffnung nach der gleichen Seite weisen, so daß die Verbindungstellen auf der einen Seite der die Spundwand mitten durchlaufenden neutralen Achse und im größten Abstand von dieser Achse liegen.In contrast, according to the present invention, the strips of the trough-shaped Sheet pile panels are shaped in such a way that the panels all face the same side with their trough opening when they are lined up, so that the connection points on one side of the sheet pile wall running through the middle neutral axis and at the greatest distance from this axis.

Als Ausführungsbeispiele der Erfindung sind auf der Zeichnung Spundwandtafeln im Querschnitt dargestellt. Dabei sind die angrenzenden Teile der anschließenden Tafeln sowie die ursprüngliche Form der Leiste d strichpunktiert angedeutet.As exemplary embodiments of the invention, sheet piling panels are shown in cross section in the drawing. The adjoining parts of the subsequent panels and the original shape of the bar d are indicated by dash-dotted lines.

Die in Fig. 1 im wagerechten Schnitt veranschaulichte Spundwandtafel α besitzt den Querschnitt eines Troges und ist mit Flansehen b, c versehen, von deren einem der Flügel d, wie gestrichelt angedeutet, zunächst unter etwa einem rechten Winkel absteht. Dieser Flügel d wird nach dem Walzen der Tafel so umgebogen, daß er mit dem Flansch b einen etwa D-förmigen Hohlraum e einschließt, dessen Wände b und d sich jedoch an einer 35 The sheet pile panel α illustrated in horizontal section in FIG. 1 has the cross section of a trough and is provided with flanges b, c , from one of which the wing d, as indicated by dashed lines, initially protrudes at approximately a right angle. After the sheet has been rolled, this wing d is bent over so that with the flange b it encloses an approximately D-shaped cavity e , the walls b and d of which, however, are at a 35

Ecke nicht vollständig berühren, so daß an dieser Stelle ein Längsschlitz f verbleibt.Do not touch the corner completely, so that a longitudinal slot f remains at this point.

Der andere Flansch c hat beim Walzen einen Längswulst g erhalten, dessen Profil etwa gleich dem Querschnitt des Hohlraumes e ist, so daß er sich in den Hohlraum einschieben läßt.The other flange c has received a longitudinal bead g during rolling, the profile of which is approximately equal to the cross section of the cavity e , so that it can be pushed into the cavity.

Bei der Ausführung nach Fig. 2 ist der Flansch b mit einer im Querschnitt halbkreisförmigen Ausnehmung k versehen und, der Flügel d ist ursprünglich in der gestrichelten Lage und Form hergestellt. Nach dem Walzen ist der Flügel d zu der ausgezogen gezeichneten Lage gebogen worden. Auch in diesem Falle ist der andere Flansch jeder Tafel, wie strichpunktiert angedeutet, so gestaltet, daß er in die Ausnehmung h paßt.In the embodiment according to FIG. 2, the flange b is provided with a recess k which is semicircular in cross section and the wing d is originally produced in the position and shape shown in dashed lines. After rolling, the wing d has been bent to the position shown in solid lines. In this case, too, the other flange of each panel, as indicated by dash-dotted lines, is designed so that it fits into the recess h.

Zwecks Herstellung einer Spundwand werden die Tafeln so aneinandergereiht, daß alle Trogöffnungen nach der gleichen Seite weisen. Die Verbindungstellen liegen dabei alle auf dieser selben Seite der Spundwand in der größtmöglichen Entfernung von der neutralen Achse der Tafeln. Dabei liegen die neutralen Achsen der einzelnen Tafeln alle in einer Geraden, die somit eine durchgehende neutrale Achse der ganzen Spundwand darstellt. Dadurch ist die Spundwandbreite auf das Vollständigste zur Erzielung eines großen Wider-Standsmomentes ausgenutzt.For the purpose of making a sheet pile wall, the panels are strung together so that all Point the trough openings on the same side. The connection points are all on this same side of the sheet pile wall as far away as possible from the neutral one Axis of the panels. The neutral axes of the individual tables are all in a straight line, which thus represents a continuous neutral axis of the entire sheet pile wall. Through this the sheet pile wall width is as complete as possible to achieve a large resistance torque exploited.

Claims

the pulling out of the panels is undesirable, but in known constructions a precondition for achieving the desired resistance torque-forming fixed rust in the connecting joints, is absolutely unnecessary in the embodiment according to the present invention. But if you wanted to achieve the required rigidity of the connections in those ίο constructions of the individual panels simply by appropriately designing the connecting strips, they were given such a cumbersome shape that it would be very difficult or impossible to use them with to roll the board in one piece. According to the present invention, the strips can be made so simple that they can be rolled with their board in one piece, which, in addition to the simplicity of manufacture, has the known advantage that the connection points remain unsweatened by the omission of the rivets that often loosen. The rolling of the connecting strips surrounding the adjacent strips of one edge of the board is possible because they still correspond to their purpose even if, prior to the final shaping, they simply consist of a strip located in the longitudinal direction of the board and a vertical strip, with no overlapping strips Parts of them are present. Godfather τ-An Proverbs:

1. Trough-shaped bung wall panel made of metal with connecting strips at the leg ends, characterized in that the strips are shaped so that the panels when lined up, all point with their trough opening on the same side, like this that the connection points on one side of the sheet pile wall running through the middle neutral axis and at the greatest distance from this axis.

2. sheet piling according to claim i, characterized in that the Connecting strips are bent in such a way that they lie flat in the back of the sheet pile wall even in the coupled state (Fig. 1).
