Description

Connecting element for a sheet pile wall

The invention relates to a connecting element for a sheet pile wall with several sheet piles. The invention further relates to a sheet pile arrangement and a sheet pile wall.

Sheet piles and sheet pile walls with sheet piles are basically known from the state of the art, for example from DE 20 2016 101 909 U1.

Driving sheet piles into a subsoil such as soil typically requires large forces. Due to the large forces involved, installing sheet pile walls also usually requires a lot of energy.

Another problem that occurs with conventional sheet piles and sheet pile walls is that the sheet piles and other elements required for a sheet pile wall, such as connecting elements, often have to be transported over long distances to the site of use. Transport usually requires a lot of space, which means that transporting the materials required for the sheet pile wall can be logistically complex and can incur high costs. Another problem with conventional sheet piles and sheet pile walls is that even small deviations in the positioning of the Elements of the sheet pile wall are out of position or there are small deviations in the dimensions of the elements required for the sheet pile wall from the target dimensions, as in such cases a high level of labour is regularly required and additional material is needed.

The invention is therefore based on the object of providing an improved solution which addresses the problems mentioned. In particular, the object of the invention is to provide a solution which enables more flexibility and more variation options when installing sheet pile walls, while also reducing the space required for transporting the elements required for the sheet pile wall.

According to a first aspect, the object is achieved by a connecting element according to claim 1. According to this, a connecting element is provided for a sheet pile wall with a plurality of sheet piles, wherein the connecting element has a longitudinal extension running parallel to a driving direction, wherein the connecting element has a straight section which extends in a direction transverse to the longitudinal extension along a straight line, wherein the straight section has a first inner side and a first outer side, wherein the connecting element has a connecting section for producing a connection between the connecting element and a sheet pile, wherein the connecting section has a second inner side and a second outer side.

According to the invention, an outer circular arc-shaped transition section is arranged between the first outer side and the second outer side, wherein the first outer side and the second outer side are arranged transversely to the longitudinal extension substantially orthogonal to one another, and wherein an inner circular arc-shaped transition section is arranged between the first inner side and the second inner side, wherein the first inner side and the second inner side enclose an angle of less than 90°, wherein the connecting element has a width transversely to the longitudinal extension in the direction parallel to the straight line, and has a depth orthogonal to the straight line, wherein the connecting section has a minimum width extension adjacent to the transition section and a maximum width extension in the direction parallel to the width, wherein the maximum width extension is at most a factor of 3 greater than the minimum width extension.

A driving direction is to be understood in particular as the direction in which a sheet pile wall, and thus also the components extending along a sheet pile wall, are driven into the subsoil, in particular by ramming the sheet pile wall into the ground. In the majority of cases, the ramming direction is perpendicular to the ground surface. The ramming direction is therefore usually vertical when installed. However, there are also ramming directions that run parallel to the horizontal, for example when sheet pile walls or sheet piles for sheet pile walls are driven into mountains or hills, for example to support a tunnel. The ramming direction corresponds in particular to the longitudinal extension direction of the sheet pile wall. If the connecting element is attached to a sheet pile wall, the longitudinal extension of the connecting element preferably runs parallel to the longitudinal extension direction of the sheet pile wall. A longitudinal extension or a longitudinal extension direction or a longitudinal axis of a connecting element or a sheet pile or a reinforcing element is understood in the context of the present disclosure to mean the extension of the respective object in the ramming direction.

It is preferred within the scope of the present disclosure if the cross section of the connecting element and the cross section of the sheet pile are substantially constant along the longitudinal extension or longitudinal extension direction.

It is preferred that the connecting element comprises or consists of steel. It is preferred that the sheet pile comprises or consists of steel.

The connecting element is in particular designed in such a way that it cannot form a positive connection with an identically shaped connecting element.

The connecting section of the connecting element is preferably designed as a male connecting section. The connecting section is designed in particular to form a connection with a lock of an adjacent Larssen sheet pile. A Larssen lock is understood to mean in particular a hook strip into which a hook strip of a sheet pile of the sheet pile wall can engage, the hook strip extending in an arc from a web of the connecting element and being provided with a mouth opening between the web and the end section.

The connecting section preferably has a quasi-triangular cross-section transverse to the longitudinal extension, wherein in particular one corner of the triangle is rounded, one corner of the triangle is bevelled and one corner lies in the transition area.

The outer circular arc-shaped transition section is in particular circular arc-shaped transverse to the longitudinal extension. The inner circular arc-shaped transition section is in particular circular arc-shaped transverse to the longitudinal extension. The first inner side and the second inner side preferably enclose an acute angle transverse to the longitudinal extension, in particular an angle of less than 90°. As a result, the connecting section widens starting from the transition section in the direction of the second end section. The angle is to be understood in particular as the angle between the direction of the extension of the first inner side transverse to the longitudinal extension and the direction of the extension of the second inner side transverse to the longitudinal extension.

The connecting element has a width transverse to the longitudinal extension in the direction parallel to the straight line and a depth orthogonal to the straight line. The connecting section in the direction of the width has a minimum width extension adjacent to the transition section and a maximum width extension. A minimum width extension is to be understood in particular as the extension of the connecting section in the direction of the width at the point on the connecting section where the connecting section transitions into the transition section, this preferably being the point on the connecting section with the smallest width of the connecting section. In particular, the minimum width extension is to be understood as the extension of the width of the connecting section in the region of the transition to the transition section. The maximum width extension is to be understood in particular as the extension of the width of the connecting section where the width is greatest, the maximum width extension is preferably arranged in the outer region of the connecting section.

One advantage of the connecting element described here is that the connecting element can be connected to a sheet pile and then form a positive connection with the sheet pile that has a relatively small amount of gaps. As a result, when the connecting elements are driven in when they are connected to sheet piles, relatively little soil material, such as earth, gets into the gaps in the connection that are located in the area of the connection between the connecting element and the sheet pile. Due to the small amount of gaps, the connecting elements can be used together with Sheet piles can be inserted into the subsoil with relatively little effort and therefore with relatively little energy expenditure.

A further advantage is that such connecting elements can be used flexibly and can be used to compensate for deviations from the target positions and deviations from the target dimensions of the elements of a sheet pile wall to be installed.

A further advantage is that the space required for transporting the connecting elements is relatively small.

A further advantage is the straight, non-hooked cross-sectional shape, which surprisingly enables particularly strong yet flexible connections to be made with known sheet pile connection interfaces.

It is particularly preferred that the maximum width extension is greater than the minimum width extension by a factor of at most 2.5, preferably by a factor of at most 2.2, particularly preferably by a factor of at most 2.1, in particular by a factor of at most 2. It is particularly preferred if the maximum width extension is approximately twice as large as the minimum width extension.

According to a preferred embodiment, the angle is less than 75°, preferably less than 65°, particularly preferably less than 60°, and at least 45°, preferably at least 50°, particularly preferably at least 52°. The angle is to be understood in particular as the angle formed by the extension of the first inner side transversely to the direction of the longitudinal extension and by the extension of the second inner side transversely to the direction of the longitudinal extension. It is particularly preferred if the first inner side and the second inner side are aligned at an angle of 55° to one another.

It is particularly preferred that the first inner side and the first outer side are arranged parallel to one another. Preferably, the straight section has a constant thickness.

Preferably, the straight portion has a first end portion which preferably extends orthogonally to the straight line and parallel to the longitudinal extension. It is particularly preferred that the width is greater than the depth.

Preferably, the width is at least twice as large, particularly preferably at least three times as large, in particular at least four times as large as the depth.

Such a larger width compared to the depth has the advantage that there are no gaps between the connecting element and the area of a reinforcing element to which the connecting element can be connected. Since such gaps typically have a negative effect on the ramming process, in particular because they require more energy for ramming, the effort and energy required for installing sheet pile walls can be reduced by using a connecting element designed in this way.

It is particularly preferred that the connecting element consists of the connecting portion, the straight portion and a transition portion which forms a transition between the connecting portion and the straight portion.

It is particularly preferred that the straight section extends from the transition section in the direction of the end section along the straight line. The straight section preferably has no curvature relative to the straight line. Preferably, with the transition section there is only one section in which the connecting element is curved.

It is particularly preferred that the outer circular arc-shaped transition section describes a circular arc section of a quarter circle transversely to the longitudinal extension. Preferably, the two ends of the outer circular arc-shaped transition section run orthogonally to one another.

It is particularly preferred that the second outer side extends straight from the outer circular arc-shaped transition section to a bevel. The second outer side extends transversely to the direction of the longitudinal extension, preferably without curvature or orthogonal to the straight line. A bevel is to be understood in particular as a bevelled surface that is produced by machining the edge of a workpiece. The bevel serves in particular to ensure that the resulting shape of the connecting section ensures good engagement in a connecting section of a sheet pile. In addition, the bevel avoids a sharp edge, which reduces the risk of injury during handling.

Preferably, the second outer side extends transversely to the longitudinal extension at least along half the length of the depth.

It is particularly preferred that the connecting portion has a second end portion which preferably runs parallel to the straight line, wherein the second end portion preferably extends from the bevel to a further circular arc-shaped portion, wherein the bevel is connected to the second outer side and the further circular arc-shaped portion is connected to the second inner side.

It is particularly preferred that the connecting portion is designed to produce a connection between the connecting element and at least one sheet pile.

It is particularly preferred that the connecting element has several connecting sections.

It is particularly preferred that the connecting element has a second straight section and a second connecting section, wherein the straight section is connected to the second straight section, wherein the straight section preferably extends orthogonally to the second straight section. The straight section extends in particular transversely to the direction of the longitudinal extension orthogonally to the second straight section.

Preferably, the straight section and the second straight section are arranged in an L-shape, so that the straight section and the second straight section have an L-shaped cross section transverse to the direction of the longitudinal extension.

Preferably, the second connecting section is connected to the second straight section via a second transition section, wherein preferably the connecting section and the second connecting section are of uniform design, wherein particularly preferably the connecting section and the second connecting section are aligned with each other rotated by 90° about an axis parallel to the longitudinal extension. Preferably, the connecting section and the second connecting section have a uniform cross-sectional shape transverse to the direction of the longitudinal extension. It is particularly preferred that the second straight section is shorter than the straight section.

It is particularly preferred that the connecting element has a third straight section and a third connecting section, wherein the straight section is connected to the second straight section and the third straight section, wherein preferably the straight section extends orthogonally to the second straight section and orthogonally to the third straight section, wherein particularly preferably the straight section, the second straight section and the third straight section together form a T-shaped cross section transverse to the longitudinal extension.

Preferably, the connecting section, the second connecting section and the third connecting section are of uniform design. The connecting section, the second connecting section and the third connecting section preferably have a uniform cross section transverse to the direction of the longitudinal extension.

It is particularly preferred that the connecting element comprises three straight sections, with a connecting section being arranged on at least two of the three straight sections. A connecting element can also be arranged on all three of the three straight sections.

It is particularly preferred that the connecting element has a first weld line running parallel to the longitudinal extension and that a plurality of weld seams spaced apart from one another are arranged along the first weld line, wherein the connecting element preferably has a second weld line running parallel to the longitudinal extension and spaced apart from the first weld line, wherein a plurality of weld seams spaced apart from one another are arranged along the second weld line. Preferably, the weld seams arranged along the first weld line and the weld seams arranged along the second weld line are arranged alternately in the direction of the longitudinal extension.

A weld line is to be understood in particular as a straight line which is arranged parallel to the longitudinal extension, along which several weld seams can be arranged, which serve in particular to connect the connecting element to another component or to connect parts of the connecting element to one another. Such an alternating arrangement of the welds can lead to improved mechanical properties, for example because crack growth due to the interrupted welds can be reduced along the weld lines. In addition, less material is required for the welds.

According to a further aspect, the object mentioned at the outset is achieved by a sheet pile arrangement for a sheet pile wall, comprising a sheet pile which extends parallel to the longitudinal extension, wherein the sheet pile has a connecting region, a reinforcing element which extends parallel to the longitudinal extension, a connecting element as described here, wherein the straight section of the connecting element is connected to the reinforcing element, in particular in a materially bonded manner, and wherein the connecting section of the connecting element forms a positive connection with the connecting region of the sheet pile.

The sheet pile can be designed, for example, as an S-shaped or Z-shaped sheet pile. The sheet pile preferably has a connecting area that can accommodate and enclose the connecting section of the connecting element, so that a positive connection is formed between the sheet pile and the connecting element.

A reinforcing element is understood in particular to mean a profile steel, i.e. a semi-finished metal product made of steel with a defined shape, for example rolled, drawn or pressed, whereby the cross-section is the same over the entire length.

It is particularly preferred that the connecting element is welded to the reinforcing element, and preferably the connecting element is welded to the sheet pile.

It is particularly preferred that the reinforcing element is designed as a T-beam, wherein the T-beam has a web and a flange, wherein the connecting element is preferably welded to the flange on the side of the flange facing the web. A flange is understood to mean in particular the outer leg and a web is understood to mean in particular the connecting middle part of the profile.

Preferably, the reinforcing element is designed as a double-T-beam, wherein the double-T-beam has a web and two flanges, wherein preferably on a side of one of the flanges facing the web, a connecting element is connected to this Flange is welded, wherein particularly preferably connecting elements are welded to the flanges on both sides of the flanges facing the web. Preferably, the double-T beam has two flanges as outer parts and a web connecting the two flanges as a connecting middle part.

Preferably, the reinforcing element is essentially round-tube-shaped, with a connecting element preferably being welded to the reinforcing element in the region of the first end section. Round-tube-shaped is to be understood in particular as a cross-sectional design transverse to the direction of the longitudinal extension in the form of a round tube.

According to a further aspect, the object mentioned at the outset is achieved by a sheet pile wall comprising a sheet pile arrangement as described here, wherein the sheet pile wall has a plurality of reinforcing elements, to each of which at least one connecting element as described here is welded on both sides in the region of the straight section and/or in the region of the first end section, wherein the connecting sections of the connecting elements are each positively connected to sheet piles.

It is particularly preferred that an intermediate element is arranged between two sheet piles, which is connected to these sheet piles in a form-fitting manner. The intermediate element can, for example, have a so-called omega cross-section.

It is particularly preferred that the connecting elements arranged along the sheet pile wall are arranged rotated by 180° relative to one another in relation to the direction of the longitudinal extension. It is particularly preferred if the connecting elements along the sheet pile wall are arranged rotated by 180° relative to the adjacent connecting elements in relation to the direction of the longitudinal extension. The connecting sections of the connecting elements preferably point in different directions, in particular rotated by 180° relative to one another, in particular alternately along the sheet pile wall.

The connecting element 10 has a parallel to a driving direction

Longitudinal extension L, which in the view shown here in Fig. 1 a is orthogonal to the Drawing plane or in the direction of view. The connecting element has a width B transverse to the longitudinal extension L and a depth A orthogonal to the width B. The width B is greater than the depth A.
