Description

Spundbohlen-Verbϊndunαseiement Sheet pile Verbϊndunαseiement
Die Erfindung betrifft ein Verbindungselement für Spundbohlen nach dem Oberbegriff des Anspruchs 1.The invention relates to a connecting element for sheet piles according to the preamble of claim 1.
Derartige Verbindungselemente dienen zum Verbinden von Spundbohlen, aus denen eine Spundwand aufgebaut ist. Häufig werden die Verbindungselemente dazu verwendet, die Anschlusselemente der jeweilig letzten Enden der Spundbohlen zweier Spundwände, in einem Winkel zueinander verlaufend miteinander zu verbinden. Beispiele für derartige Verbindungselemente sind der deutschen Patentanmeldung DE-Al-39 07 348 zu entneh- men. Die dort beschriebenen Verbindungselemente dienen zum Anschluss an sogenannte Larssen-Spundbohlen oder Spundbohlen des Knopf-Klauen-Typs.Such connecting elements are used for connecting sheet piles, of which a sheet pile wall is constructed. Frequently, the connecting elements are used to connect the connecting elements of the respective last ends of the sheet piles of two sheet piles, extending at an angle to each other. Examples of such connecting elements can be found in the German patent application DE-Al-39 07 348. The connecting elements described therein serve for connection to so-called larssen sheet piles or sheet piles of the button-claw type.
Beim Niederrammen der Spundbohlen und der Verbindungselemente treten zwischen diesen Bauteilen hohe Zug- und Scherkräfte auf, die gegebenenfalls so groß sein können, dass die Bohlen bzw. Verbindungselemente aus ihrer Verhakung herausspringen. Hierdurch kann die Festigkeit der Spundwand insgesamt geschwächt werden. Ferner ist die Spundwand an diesen Stellen nicht mehr wasserdicht.When Niederrammen the sheet piles and the connecting elements occur between these components high tensile and shear forces, which may be so great that the planks or fasteners jump out of their entanglement. As a result, the strength of the sheet pile wall can be weakened overall. Furthermore, the sheet pile wall is no longer waterproof at these locations.
Der Erfindung liegt die Aufgabe zugrunde, ein Verbindungselement anzugeben, das einfach herzustellen ist und mit dem auch hohe Kräfte beim Niederrammen der Verbindungselemente und der Spundbohlen aufgefangen werden können.The invention has for its object to provide a connecting element that is easy to manufacture and with the high forces during the low ramming of the connecting elements and the sheet piles can be collected.
Diese Aufgabe wird erfindungsgemäß durch ein Verbindungselement mit den Merkmalen nach Anspruch 1 gelöst. Erfindungsgemäß weist das Verbindungselement eine Mittelleiste und zwei von dieser ausgehende Hakenleisten auf, die gemeinsam eine im Querschnitt C-förmige Klauenleiste bilden. Die Enden der Hakenleisten weisen aufeinander zu und begrenzen mit ihren Enden ein offenes Maul. Ferner schneiden sich die verlängerten Mittellinien der Enden der Hakenleisten außerhalb des offenen Maules. Von der Klauenieiste steht zumindest eine Anschlussleiste ab, die eine gerade Halsleiste und eine im Querschnitt ovale Kopfleiste aufweist, wobei die Hauptachse der im Querschnitt ovalen Kopfleiste rechtwinklig zur Längsachse der Halsleiste verläuft.This object is achieved by a connecting element with the features of claim 1. According to the invention, the connecting element has a central strip and two hook strips extending therefrom, which together form a cross-sectionally C-shaped claw strip. The ends of the hook strips face each other and define with their ends an open mouth. Furthermore, the extended centerlines of the ends of the hook strips intersect outside of the open mouth. From the claw rail is at least one terminal block, which has a straight neck bar and a cross-sectionally oval header, wherein the main axis of the cross-sectionally oval header is perpendicular to the longitudinal axis of the neck strip.
Zur Klarstellung wird darauf hingewiesen,, dass die Verläufe der Mittellinien, der Hauptachsen, der verschiedenen Längsachsen sowie der Symmetrieachsen, so wie sie in der Beschreibung und den Ansprüchen Verwendung finden, immer in einer Querschnittsebene quer zur Längsrichtung des Verbindungselementes zu sehen sind.For the sake of clarity, it should be pointed out that the courses of the center lines, the main axes, the different longitudinal axes and the symmetry axes, as used in the description and the claims, are always to be seen in a cross-sectional plane transverse to the longitudinal direction of the connecting element.
Das erfindungsgemäße Verbindungselement dient insbesondere zum .Miteinanderverbin- den von Spundbohlen mit Ball-Socket-Anschlüssen. Hierbei dient die Klauenleiste zur Aufnahme des Ball-Anschlusses der Spundbohle, während der Socket-Anschluss der Spundbohle mit der Anschlussleiste des erfindungsgemäßen Verbindungselementes in Eingriff gebracht wird.The connecting element according to the invention is used in particular for . Jointing of sheet piles with ball-socket connections.

Durch die erfindungsgemäße Gestaltung der Klauen leiste "ist einerseits das Einführen der Spundbohle mit ihrem Ball-Anschluss in die Klauenleiste erleichtert, da das Maul der Klauenleiste durch den erfindungsgemäßen Verlauf der beiden Hakenleisten zueinander, gemäß dem die beiden Mittellinien sich außerhalb des Mauls der Klauenleiste schneiden, erweitert ist. Andererseits wird ein Herausspringen des Ball-Anschlusses aus der Klauenleiste durch die erfindungsgemäße Ausgestaltung der beiden Hakenleisten beim Niederrammen verhindert, da die Hakenleisten den in die Klauenleiste eingeführten Ball- Anschluss der Spundbohle weit umfassen, jedoch eventuelle Ausweichbewegungen des Ball-Anschlusses und der Klauenleiste zueinander nicht behindern. Gleichzeitig können die Hakenleϊsten die beim Niederrammen entstehenden hohen Kräfte aufnehmen und an die Mitteleiste ableiten. The inventive design of the claws bar " on the one hand facilitates the insertion of the sheet pile with its ball connection in the claw strip, since the mouth of the claw strip to each other by the inventive course of the two hook strips according to which the two center lines intersect outside the mouth of the claw strip On the other hand, a jumping out of the ball connection from the claw bar is prevented by the inventive design of the two hook strips during low rams, since the hook strips include the inserted into the claw bar ball connection of the sheet pile far, however, any evasive movements of the ball connection and At the same time, the hook springs can absorb the high forces arising during low ramming and divert them to the center bar.

In Fig. 4 ist die Vorderansicht eines zweiten Ausführungsbeispieles eines modifizierten Verbindungselementes 80 gezeigt, dass wie das erste Ausführungsbeispiel gemäß der Fig. 1 eine C-förmige Klauenleiste 82 sowie eine erste Anschlussleiste 84 aufweist. Die Abmessungen dieser Komponenten entsprechen denen der Komponenten des in Fig. 1 gezeigten Verbindungselements 10.FIG. 4 shows the front view of a second exemplary embodiment of a modified connecting element 80, which, like the first exemplary embodiment according to FIG. 1, has a C-shaped claw strip 82 and a first terminal strip 84. The dimensions of these components correspond to those of the components of the connecting element 10 shown in FIG. 1.
Zusätzlich ist bei diesem Verbindungselement 80 eine zweite Anschlussleiste 86 vorgesehen, die wie die erste Ansehlussleiste 84 gestaltet ist und eine Halsleiste 88 und eine Kopfleiste 90 aufweist. Die zweite Anschlussleiste 86 entspricht hierbei in ihren Abmes- sungen denen der korrespondierenden ersten Anschlussleiste 84. Die zweite Anschlussleiste 86 ist auf. der dem offenen Maul 92 gegenüberliegenden Seite der Klauenleiste 82 angeordnet und zur ersten Anschlussleiste 84 rechtwinklig ausgerichtet.In addition, a second terminal block 86 is provided in this connection element 80, which is designed like the first Ansehlussleiste 84 and a neck strip 88 and a header 90 has. The second terminal block 86 corresponds to this in its dimensions those of the corresponding first terminal block 84. The second terminal block 86 is on. arranged opposite the open mouth 92 side of the claw strip 82 and aligned at right angles to the first terminal block 84.
Fig. 5 zeigt in Vorderansicht die Stirnseite eines dritten Ausführungsbeispieles eines erfindungsgemäßen Verbindungselementes 100. Das Verbϊndungselement 100 hat, wie das in Rg: 1 gezeigte Verbindungselement 10, eine C-förmige Klauenleiste 102 sowie eine Anschlussleiste 104. Die Mittelleiste 106 der Klauenleiste 102 bildet jedoch gleichzeitig eine der Hakenleisten 108 und 110 einer zweiten C-förmigen Klauenleiste 112.FIG. 5 shows in front view the end face of a third embodiment of a connecting element 100 according to the invention. The connecting element 100, like the connecting element 10 shown in FIG. 1, has a C-shaped claw strip 102 and a terminal strip 104. However, the middle strip 106 of the claw strip 102 forms at the same time one of the hook strips 108 and 110 of a second C-shaped claw bar 112th
Die zweite Klauenleiste 112 ist hierbei identisch gestaltet und bemessen wie die erste C-förmige Klauenleiste 92, verläuft jedoch mit ihrer Symmetrieachse 114 rechtwinklig zur Symmetrieachse 116 der ersten Klauenleiste 102.. The second claw strip 112 is in this case designed identically and dimensioned as the first C-shaped claw strip 92, but extends with its axis of symmetry 114 at right angles to the axis of symmetry 116 of the first claw strip 102 .
Wie aus den Rg. 1 bis 5 ersichtlich, wird für alle Verbindungselemente 10, 40, 60, 80 und 100 die Kontur des Querschnittes im Bereich der Klauenleisten 12, 68, 82, 102 und 112 sowie der Anschlussleisten 30, 42, 62, 84, 86 und 104 durch eine Aneinanderreihung einzelner Kreisabschnitte mit unterschiedlichen Radien erzielt. Die Innenkontur der Klauenleisten 12, 68, 82, 102 und 112 wird in dem der Mittelleiste 14, 50, 66 und 106 zugewandten Bereich durch einen Kreisabschnitt mit einem relativ großen Radius von beispielsweise 20 mm gebildet, an den sich jeweils ein Kreisabschnitt mit einem kleineren Radius von beispielsweise 8 mm anschließt, der die Hakenleisten 16, 18, 108 und 110 begrenzt. Die Außenkonturen der Hakenleisten 16, 18, 108 und 110 verlaufen im wesentlichen parallel dazu, wobei die Leisten eine Dicke von etwa 10 mm haben.As can be seen from FIGS. 1 to 5, the contour of the cross section in the area of the claw strips 12, 68, 82, 102 and 112 as well as the terminal strips 30, 42, 62, 84 for all connecting elements 10, 40, 60, 80 and 100 , 86 and 104 achieved by a juxtaposition of individual circular sections with different radii. The inner contour of the claw strips 12, 68, 82, 102 and 112 is formed in the central strip 14, 50, 66 and 106 facing region by a circular section with a relatively large radius of, for example, 20 mm, to each of which a circular section with a smaller Radius of for example 8 mm connects, which limits the hook strips 16, 18, 108 and 110. The outer contours of the hook strips 16, 18, 108 and 110 extend substantially parallel thereto, wherein the strips have a thickness of about 10 mm.
Bei den in den Rg. 1 und 4 gezeigten Verbindungselementen 10 und 80 schließt sich an die Außenkontur der Hakenleiste 16 wiederum ein Kreisabschnitt mit' einem relativ kleinen Radius von beispielsweise 8 mm an, der in die Halsleiste 32 bzw. 88 übergeht. Der Kreisabschnitt, der den oberen Teil der Kopfleiste 34 bzw. 90 begrenzt, hat wiederum einen vergleichsweise großen Radius von beispielsweise 16 mm. Die übrigen Kreisabschnitte werden so gewählt, dass sich sanfte Übergänge ergeben. Die Verbindungselement 10, 40, 60, 80 und 100 sind in den Fig. 1 bis 6 etwa im Maßstab 1,5:1 dargestellt, so dass die Höhe des Verbindungselementes 10, 40, 60, 80 bzw. 100 etwa 75 mm beträgt. Die größte Ausdehnung der Innenkontur der Klauenleisten 12, 68, 82 bzw. 102 und 112 beträgt etwa 28 bis 30mm, wobei die Maulöffnung etwa 15mm beträgt. Die größte Ausdehnung der Kopfleisten 34 und 90 in Richtung der Hauptachse 38 beträgt etwa 24 mm.In the examples shown in the Rg. 1 and 4, connecting members 10 and 80 of the hook strip 16 is a circular segment joins to the outer contour again with 'a relatively small radius of, for example 8 mm at which merges into the neck strip 32 and 88, respectively. The circle section which delimits the upper part of the head strip 34 or 90, in turn, has a comparatively large radius of, for example, 16 mm. The remaining sections of the circle are chosen so that gentle transitions result. The connecting elements 10, 40, 60, 80 and 100 are shown in FIGS. 1 to 6 approximately on a scale of 1.5: 1, so that the height of the connecting element 10, 40, 60, 80 and 100 is approximately 75 mm. The largest extent of the inner contour of the claw strips 12, 68, 82 and 102 and 112 is about 28 to 30mm, wherein the mouth opening is about 15mm. The largest extent of the head strips 34 and 90 in the direction of the main axis 38 is about 24 mm.
Abweichungen von diesen Maßen sind natürlich möglich. So kann zum Beispiel der Querschnitt der Innenkontur der Klauenleisten 12, 68, 82, 102 und 112 gestreckter ausfallen.Deviations from these dimensions are of course possible. Thus, for example, the cross section of the inner contour of the claw strips 12, 68, 82, 102 and 112 may be more elongated.
