Set of components for erecting a combi sheet pile wall

The invention relates to a set of components for erecting a so-called combi sheet pile wall made of double-T-beams, connecting elements and conventional sheet piles with a Z-shaped cross-section, which have a claw strip on one longitudinal edge and a button strip on their other longitudinal edge.

In such a combination sheet pile wall, sheet piles can be inserted between two double-T beams using the connecting elements, resulting in a double-walled combination sheet pile wall in which the space between the sheet piles can be filled if necessary.

When constructing the combined sheet pile wall, the double-T beams, so-called Peiner beams, are first fitted with connecting elements at the ends of their beam arms, which are pushed onto the ends of the double-T beam and then welded to them. A pair of Z-sheet piles is inserted into the connecting elements of two adjacent double-T beams driven into the ground and driven into the ground. This process is repeated until the combined sheet pile wall is completed.

The work involved in erecting such a combined sheet pile wall is particularly complex due to the installation and welding of the connecting elements. In addition, these

known connecting elements weigh about 20 kg per linear meter, so that the weight of the sheet pile wall, which directly affects the costs, becomes very high.

The invention is based on the object of specifying construction elements for a combi sheet pile wall, with which the construction of the combi sheet pile wall is facilitated and also the weight of the wall is reduced.

This object is achieved according to the invention by the features of claim 1.

Accordingly, the double-T-beams have button strips on all their longitudinal edges for the direct connection of claw strips of the conventional Z-sheet piles; the connecting elements are designed in such a way that they each accommodate the button strips of two adjacent Z-sheet piles and thus connect the sheet piles to one another.

With such a design of the structural elements, the double-T beams do not need to be prepared separately, as the Z-sheet piles with their claw strips can be connected directly to the button strips of the beams. The pairs of sheet piles located between two adjacent double-T beams are connected to the connecting elements via their button strips and then rammed into the ground together. This means that only one connecting element is required for the sheet piles between two adjacent double-T beams and not two connecting elements as before. This reduces the weight of the entire sheet pile wall, as the connecting elements can also be made relatively light: they weigh around 12 - 13 kg per linear meter. Furthermore, fewer

Welding work is necessary so that the combined sheet pile wall can be constructed cost-effectively and with little expenditure of time.

According to a preferred embodiment of the invention, the button strips of the double-T beams have a substantially nose-shaped cross-section and all point substantially perpendicularly from the beam in one direction. These button strips, which have a nose-shaped cross-section, are then grasped by the claws of the conventional Z-sheet piles.

The connecting element according to the invention preferably has a substantially flat base strip, which has on its longitudinal edges a hook strip with a nose-shaped cross-section and a central web strip pointing in the same direction as the hook strip. At the end of the web strip, two limiting strips are provided pointing in the direction of the two outer hook strips, so that a hollow space is defined by a hook strip and a limiting strip as well as a part of the base strip, into which a button strip of a Z-sheet pile can be inserted.

The invention is explained in more detail in an embodiment with reference to the drawing. In this:

Figure 1 shows a cross-section through a double-T-beam according to the invention with rolled button strips on all longitudinal edges;

Figure 2 shows a cross section through a connecting element according to the invention for connecting two adjacent sheet piles; and

Figure 3 is a plan view of part of a combi sheet pile wall constructed with the components shown in Figures 1 and 2 and with conventional Z-sheet piles.

Figure 1 shows a cross-section of a double-T beam 1 for constructing a combination sheet pile wall. The beam 1 consists of two T-beams 2 and 3, which are connected to one another by a central connecting web 4 that forms the T-section. The free longitudinal edges of the T-beams 2 and 3 are designed as a connecting element 5 in the form of a button strip, which, as shown in the detailed drawing in Figure 1, projects essentially vertically upwards and has an approximately nose-shaped cross-section. All 4 button strips of the double-T beam 1 point in one direction, upwards as seen in the figure.

Figure 2 shows a cross-section of a connecting element 6 for connecting two adjacent sheet piles. The connecting element 6 has a substantially flat base strip 7, in this case slightly bent in the middle, on the outer longitudinal edges of which a short hook strip 8, which is approximately nose-shaped in cross-section, is arranged. For a hook strip 8, a central longitudinal plane 9 is indicated, which is slightly inclined inwards, so that the longitudinal planes 9 of the two hook strips intersect above the base strip 7 as seen in the figure. The angle between the base strip 7 and the longitudinal plane 9 is, for example, approximately 60° as shown.

In the middle of the base strip 7, a web strip 10 is provided which projects upwards as seen in the figure and which is divided into two boundary strips 11 pointing diagonally upwards. The inner walls of the web strip 10 and boundary strip 11 facing the hook strips 8 run upwards in a slight curve and end approximately in the

Extension of the longitudinal plane 9 of the hook strips 8. Together with the hook strips 8, a part of the base strip 7, the web strip 10 and the boundary strip 11 each define a cavity 12, the cross-section of which is slightly reminiscent of a trapezoid. A button strip 13 of a conventional Z-sheet pile 14 can be inserted into this cavity 12, as shown in dashed lines in Figure 2.

Figure 3 shows part of a so-called combi sheet pile wall 15. This sheet pile wall uses the aforementioned conventional Z-sheet piles 14, which have a claw strip 16 on one longitudinal edge and the aforementioned button strip 13 on the other longitudinal edge.

Two adjacent sheet piles 14 are connected to one another using a connecting element 6, whereby the connecting element 6 accommodates the button strips 13 of the sheet piles. The connecting element 6 can still be welded to the sheet piles. The sheet pile pairs 14 prepared in this way are pushed with their claw strips 16 onto the button strips 5 of two adjacent double-T beams 1, so that the claw strips 16 surround the hook strips 5 on both sides. The sheet pile pair is then rammed into the ground. This results in a combination sheet pile wall 15 with two individual sheet pile walls running parallel to one another, each made up of sheet piles 14 arranged in pairs, as shown in Figure 3.

It should be noted that the described and illustrated shapes of the button strips on the double-T beams and the strips of the connecting element are only examples; deviations are possible. It is essential that two conventional adjacent sheet piles can be connected to each other via the connecting element at their button strips and that the claw strips of the
