Definitions

  • the present invention relates to a U-profile for use in a sheet pile wall for supporting soil, concrete and the like. in civil engineering, sewer construction, etc., which has a cross-sectional shape in which two web sections extend obliquely outwards from a central flange section.
  • Sheet piling consists of a large number of U-profiles, hat-profiles or Z-profiles. They are driven into the ground and serve to support construction pits, quay walls, slope fixings etc. with respect to the ground, concrete etc.
  • the individual profiles are connected to one another via so-called profile locks, i.e. a profile has hook-shaped end regions which are inserted into the hook-shaped end regions of the adjacent profiles to form a profile lock, so that there is a wall which cannot be separated from one another in directions perpendicular to the profile axis.
  • a U-profile of the type described at the outset is known, in which the outwardly extending web sections merge into flange sections running parallel to the central flange section.
  • Hook-shaped lock halves are provided at the ends of these flange sections, which can be assembled with the lock halves of adjacent profiles to form a sheet pile wall.
  • the lock half at the end of one flange section is designed as a simple hook
  • the lock half of the other flange section is designed as a hook offset from the plane of the flange section, that is to say the central axis running through the lock half parallel to the flange section is laterally offset from the plane of the associated flange section arranged.
  • the invention is based on the idea of creating a U-profile of the type described at the outset, which is characterized by a particularly high section modulus with comparable use of materials.
  • the U-profile designed according to the invention thus has no further flange sections in the extension of the web sections, but is provided with lock halves directly in the end regions of the web sections.
  • the lock halves at the ends of the two web sections are mirror images of one another, otherwise completely identical.
  • the U-profile can be combined with other, identically designed U-profiles to form a sheet pile, whereby webs result between flange sections, which are composed of the two web sections of adjacent U-profiles arranged in mirror image to one another.
  • the profile locks are formed centrally in these webs and are not in the area of the flange sections, as in the prior art described at the beginning.
  • the web of the sheet pile wall formed from two web sections is braced centrally, by means of which the strength behavior of the sheet pile wall is improved.
  • the sheet pile wall Due to the webs formed from two web sections, the sheet pile wall is approximately twice as high perpendicular to the main plane of the sheet pile as the sheet pile wall of the prior art described at the outset, i.e. the distance between the flange sections is approximately twice as large as that of the prior art described at the beginning .
  • the sheet piling created with the U-profiles designed according to the invention can withstand higher loads with comparable material use than the sheet piling of the prior art.
  • the assembly of the U-profiles designed according to the invention results in sheet piles which have a particularly large overall height, i.e. have a particularly long bridge length.
  • the profile locks are arranged in the middle of these webs, i.e. at the ends of the respective web halves, additional bulge stability is achieved, specifically at the point of the most dangerous bulge cross-section. This increases the security against buckling or bulging in the web area.
  • the lock halves are not designed as simple hooks, but rather as hooks offset with respect to the plane of the web sections.
  • This has the advantage that when two U-profiles are put together, double-sided locking is achieved in the lock area, i.e. with shear stress in the plane of the web sections in the direction of the respective lock halves, the curved hook sections are each supported on an associated section of the other lock half, namely on both sides.
  • Such an effect is not achieved in the prior art described at the outset, in which a simple hook interacts with a laterally offset hook.
  • the solution according to the invention thus ensures particularly good locking in the lock area, so that particularly good thrust protection is achieved.
  • the U-profile is designed in such a way that the parallel and laterally offset sections of the web sections run outwards to the web section main plane and that the central plane of the lock half is laterally offset outwards with respect to the web section main plane.
  • the distance between the parallel and laterally offset sections and the bent-back parallel end sections of the web sections is expediently somewhat larger than the thickness of the end section.
  • This embodiment allows a good insertion of the end portion of the lock half of another U-profile in between the parallel and laterally offset section and the bent back parallel end section available space, however, at the same time ensures a firm locking, since the end section can hardly move back and forth in the existing space. Rather, the end section of the adjacent U-profile essentially fills this space in the lateral direction, so that almost a positive connection is achieved. This increases the stability or strength of the profile lock.
  • bent-back parallel end section of the web section it is furthermore expedient for the bent-back parallel end section of the web section to extend back over the main part of the parallel and laterally offset section thereof.
  • the end portion engages in the cavity of the lock half over a sufficient distance, as a result of which the locking effect is improved.
  • the ends of the end sections are supported in the respective bent-back sections of the lock halves.
  • the parallel and laterally offset sections of the web sections preferably merge into the web sections via inclined sections, rounding off the edges. This avoids sharp edges and zones of voltage peaks.
  • the angle which these inclined sections form with the web section is preferably approximately 110 °.
  • the web sections preferably form an angle of approximately 110 ° with the central flange section. It can be seen that the profile according to the invention is therefore not a pure U-profile, but rather a profile with an approximately trapezoidal cross-sectional shape.
  • the distance between the inner surface of the parallel bent-back end section and the inner surface of the web section is somewhat larger than the thickness of the parallel and laterally offset section of the web section. This ensures that after the interlocking of the lock halves of two web sections of adjacent U-profiles, the outer surface of the parallel and laterally offset section of the web section of one profile is substantially aligned with the inner surface of the web section of the other profile. In other words, the lock formed does not protrude laterally beyond the respective inner surface of the associated web section. This results in a smooth transition between the web section and the lock in the assembled state.
  • inside and outside refer to the cross-sectional shape of the U-profile, where “inside” means towards the center of the profile.
  • the U-profile designed according to the invention is preferably dimensioned such that the length of the central flange section corresponds approximately to twice the length of the web section excluding the lock half.
  • the U-profile designed according to the invention is preferably produced by cold forming. It is expediently additionally work hardened in the area of its lock halves. This results in improved sliding properties when nesting the lock halves of adjacent U-profiles.
  • the U-profile according to the invention expediently has the same material thickness everywhere. It preferably exists made of the following materials: St 37, SpS 45 or St 52.
  • the material thickness of the U-profile is preferably 3 - 10 mm.
  • the known U-profile shown in cross section in FIG. 1 has a flange section 1, from which two web sections 2 extend obliquely outwards. These web sections 2 merge into flange sections 3, which run parallel to the central flange section 1. At the free ends of the flange sections 3, lock halves are arranged, by means of which the U-profile can be assembled with further U-profiles to form a sheet pile wall.
  • the lock half is designed in the form of a simple hook 4, while the lock half on the flange section 3 shown on the left in FIG. 1 is designed as a hook offset to the plane of the flange section 3.
  • This hook is composed of an inclined section 7 formed as an extension of the flange section 3, a section 6 arranged parallel to the flange section 3, but offset to this, and the actual hook section 5.
  • Figure 2 shows three U-profiles of the type shown in Figure 1, which are assembled to form part of a sheet pile wall.
  • the locks 8 formed during assembly from the individual lock halves are arranged in the region of the flange sections 3.
  • FIG 3 shows a U-profile designed according to the invention in cross-sectional view.
  • This profile also has a central flange section 10, from which two web sections 11 run obliquely outwards.
  • the angle between the central flange section 10 and the web sections 11 is 110 ° in this special exemplary embodiment.
  • the ends of the web sections 11 merge via a rounding 13 into an obliquely outwardly extending section 12, which in turn merges via a rounding 14 into a section 15 running parallel to the plane of the web section 11, but offset to this.
  • the section 15 merges into a section 16 bent back by 180 °, which in turn merges into an end section 17 running parallel to the plane of the web section.
  • the section 15 is arranged laterally offset to the plane of the web section 11.
  • the bent back section 16 is bent back from the section 15 inwards.
  • the end section 17 extends parallel to the plane of the web section 11, specifically laterally offset outwards by an amount that is somewhat larger than the thickness of the section 15.
  • a lock half is formed in the form of a hook offset from the central plane of the web section 11.
  • the central plane of the free space 18 formed inside the hook which runs parallel to the plane of the web section 11, is offset laterally outwards to the plane of the web section 11.
  • This free space 18 has a width which is somewhat greater than the thickness of the end section 17.
  • the U-profile described above can be combined with other U-profiles to form a sheet pile, as shown in FIG. 5.
  • a U-profile which is open at the bottom in FIG. 5 is inserted between two U-profiles which are open at the top in FIG.
  • the locks 19 are arranged in the web areas, with their longitudinal axes parallel to the web sections 11.
  • Figure 4 shows the details of a lock 19 in cross section. Since both lock halves have laterally offset hooks, there is a double locking. In other words, in the event of shear stress (forces act parallel to the plane of the web sections 11), the bent sections 16 are supported on the inclined sections 12 while in the event of tensile stress in the plane of the web sections 11, the ends of the end sections 17 abut the insides of the curved sections 16.
  • Figure 6 shows an embodiment of the U-profile designed according to the invention with dimensions.
  • the material thickness of the profile is 8 mm everywhere.
  • the web sections 11 merge into the outwardly offset section 15 at an angle of 110 °.
  • the distance between the inner surface of the end section 17 and the inner surface of the web section 11 is 10.5 mm, i. H. is slightly larger than the thickness of section 15. This means that in the assembled state of two profiles, the inner surface of the web section 11 runs almost flush with the inner surface of section 15 of the other profile.
  • the free space 18 within the lock half is so large that it can accommodate the end section 17 of the adjacent lock half with sufficient play, but on the other hand ensures a good locking.
  • the area of the lock halves is strain hardened in a special way.
  • the offset of the lock halves with respect to the inner surface of the web section 11 is a total of 42.5 mm (measured up to the outer surface of the section 15).
  • the length of the web section (without the lock half) is 179 mm, while the length of the middle flange section is 354 mm (both measured without curves).
  • Figure 7 shows a cross section through a sheet pile wall with dimensions.
  • the overall height, ie the distance between the outer surfaces of adjacent middle flange steps 10, is 456 mm in this case, ie is significantly higher than in the prior art described at the beginning.
  • the lock distance is 580 mm, while the pitch (double lock spacing) is 1160 mm.
  • the light profile described above is produced in particular by cold working. It has a double-sided lock lock with excellent push and dent protection. Both lock halves are of the same design (only mirror images), so that simple manufacture results. Arranging the locks in the middle of the web area of the sheet pile results in improved buckling stability and stability against buckling.
