Definitions

  • the invention relates to a connecting element for sheet piles according to the preamble of claim 1.
  • connecting elements are known from DE 20 18 119 AI. These connecting elements are used for angular connections between sheet piling with so-called Larssen locks and show a slightly asymmetrical S-profile, the two oppositely curved parts of which form locks of different shapes with successively opposite sides of the S-profile open lock grooves.
  • the hook strip on one side forms a narrowed opening with a curved inner border and allows Larssen locks from adjacent sheet piles to be inserted at different angles between about 90 and 135 °.
  • the opposite hook bar only allows a rigid connection with a lock of an adjacent Larssen sheet pile.
  • Hot-rolled profiles are usually profiles that are mainly used in extreme water resources. It is necessary that the smallest possible tolerances are achieved due to the shape of the lock. This is the only way to retain the water present.
  • the invention has for its object to provide a connecting element of the type in question, which can be easily connected to the lock of an already rammed sheet pile by ramming without expensive work.
  • a connecting element according to the invention is an extruded profile which, in order to keep the manufacturing tolerances very low, is subsequently treated in a rolling and straightening process.
  • the inside of the at least one hook bar follows a continuous arc, this arc and the mouth opening of the hook bar are designed so that when the hook bar, e.g. B. a Larsen lock of a sheet pile this continuously around the Tip of the end portion of the hook bar of the connecting element is pivotable in a certain angular range.
  • the limits of this angular range are determined by the fact that on one side the hook strip of the sheet pile strikes a contact surface of the web and on the other side on the arcuate inside of the hook strip of the connecting element.
  • a decisive feature is that, in contrast to the prior art, the larssen locks of the sheet piles to be inserted into the hook strips of the connecting element can be pivoted about the tip of the end section. All that is needed here is the construction of a Larssen castle; a form-fitting system as in the prior art is not necessary.
  • the curved hook strip is essentially constant semicircular or crescent-shaped for all connecting elements.
  • the end section of this hook strip points essentially perpendicularly towards the web of the connecting element which serves as a contact surface; with S-shaped hook strips, they can extend vertically from the web; In this case too, the web at the starting point of the hook strip serves as a contact surface, which, in conjunction with the mouth opening, prevents the profiles from sliding out.
  • the connecting element can be rotated continuously Larssen Castle possible, and in many cases even after ramming.
  • the connecting elements can also be designed very slim, that is to say be built “substantially from webs of the same, and more particularly small thickness. This has the not inconsiderable advantage that the connecting elements with the same strength are much lighter than known connecting elements, so that the material costs in the manufacture are reduced.
  • the connecting elements are e.g. S-shaped, T-shaped or a combination of both profiles.
  • the resulting central web creates a mechanically very stable profile, which also ensures the ramming strength of the profiles.
  • Figure 1 is a schematic plan view of a part of a corner connection of two sheet piling or a part of a Kreisramung means double planks with S-shaped connecting elements according to the invention.
  • FIG. 2 shows a cross section through an essentially T-shaped connecting element according to the invention with a further V-shaped hook strip
  • FIG. 3 shows a cross-section approximately S-shaped connecting element according to the invention with an additional V-shaped hook strip

  • FIG. 6 shows a cross section through a connecting element with a curved hook strip according to the invention and a hook strip in the form of a Larssen lock.
  • FIG. 1 schematically shows a sheet pile wall running in a corner, which is used for piling, from a plurality of double planks 1 with so-called Larssen locks, the sheet piles being connected to one another in the corner region by S-shaped connecting elements 2c according to FIG. 4.
  • FIG. 2 shows a connecting element 2a with an approximately T-shaped cross section.
  • This connecting element has a central web 3 corresponding to the T-smear, which is provided with a V-shaped hook strip 4 at its lower end in the figure.
  • hook strips 5 run on both sides, which after an internal rounding 6 initially extend approximately perpendicular to the web 3 and merge into an end section 7 which is approximately semicircular in cross section, the end of which is rounded and points towards the central web 3 .
  • a jaw opening 8 is delimited by the end section 7 and the web 3, a hook strip 9 of a conventional Larssen sheet pile 10 being able to be introduced through this jaw opening.
  • the jaw opening has a width of 20 millimeters.
  • the web 3 forms a contact surface 11 in the area of this jaw opening, the dimensions of the jaw opening and the end section 7 of the hook strip 5 being dimensioned such that the sheet pile 10 can be pivoted in the hook strip, but cannot be pivoted out or pushed out of it. If the sheet pile 10 is shifted, it bears with its hook strip 9 on the contact surface 11, but remains in the hook strip 5 of the connecting element 2a. If the hook bar is pivoted in the other direction around the tip of the end section, it finally lies in the arch of the hook bar at at least one attachment point 11a as shown in FIG. 3. This position, like the one above, is a stable end position.
  • This connecting element 2a is also provided with a notch 12 in the area between the two hook strips 5, so that the entire connecting element is essentially composed of webs of the same thickness, i.e. that the web 3 and the two hook strips have essentially the same thickness over their entire course.
  • the connecting element 2a is produced by extrusion and subsequent straightening, so that the tolerances are kept very low, particularly in the area of the jaw opening.
  • a profile can be easily rammed into already driven sheet piles by vibration or impact; a firm connection, e.g. B. a welded joint with a sheet pile before ramming as in the prior art is not necessary.

  • the upper hook strip 5 in the figure starts almost perpendicularly from the web 3 and runs essentially crescent-shaped, with the end section 7 of this hook strip practically opposite the starting point on the web 3, so that there is a contact surface 11 for the hook strip 9 of a sheet pile 10 is formed.
  • the hook strip running downward in FIG. 4 is bent approximately semicircularly, so that the end section 7 again points approximately towards the web 3, the contact surface 11 for a Larssen lock inserted into the hook strip 5 being formed in the area opposite the end section 7 .
  • the dimensions of the jaw openings 8 and the end sections of the two hook strips 5 are in turn such that the lock 9 of the sheet pile 10 can be pivoted in the hook strip, as indicated in the figure by approximately 60 °, but not by moving or pivoting the hook bar can be removed.
  • this connecting element In the case of this connecting element, if the tensile load is possibly rotating by the adjacent sheet piles, the force is reversed, as a result of which the connection between sheet piles and connecting element is closed. In the event of a pressure load, the curves of the hook strips are relieved and the entire pressure is transferred to the web.
  • This connecting element 2c is also produced by extrusion with subsequent straightening, the thickness of the profile being virtually constant over its entire length.

Due to the possibility of continuous pivoting, angle and dimension deviations in the sheet pile wall in the area of the connection with the connecting element can be largely compensated for, so that the sheet pile box can be closed. Otherwise, it is generally not necessary to use passport planks that are difficult to interpose.
  • FIG. 5 shows a so-called welding corner 2d, which is formed by opening the connecting element in accordance with FIG. 4.
