Definitions

  • the invention relates to a steel sheet piling profile in double T-shape, and a tool for its production.
  • a gattunssiees sheet pile profile and a generic tool are eg off DE 613 210 C known.
  • Sheet pile wall profiles in double T-shape are known, for example, as Peiner steel sheet piling (see section of product range "Hoesch steel sheet piling” 1/03 or "Peiner steel sheet piling 3/02 of HSP Hoesch sheet piling and Profil GmbH, Dortmund).
  • hot-rolled sheet piling profiles consist of two flange sections, which are connected at the center via a web.
  • the flange sections are followed by club-shaped connection end sections, which serve to receive connecting locks.
  • the flange portions extend substantially horizontally at least on the outside.
  • the flange inside, starting from the middle of the flange, can either taper in a wedge shape towards the end of the flange or, like the flange outside, have a substantially horizontal course.
  • the substantially rectangular cross-section in one of the final dimensions of the double-T profile becomes close via a roughing stand Form brought and then rolled in a finishing stand, consisting of at least one universal and edger stand, to the required final size.
  • a roughing stand Form brought and then rolled in a finishing stand, consisting of at least one universal and edger stand, to the required final size.
  • the rough rolling can be limited to only a few rolling passes, since there is already a close-to-near cast cross-section.
  • the finishing mill each consists of a set of rollers for the external and internal machining of the pre-profile.
  • these sheet pile profiles can be connected to the connection locks either with itself, so that a closed wall is made of individual support elements with high resistance moment, or they can be used for a mixed sheet pile wall, via the connection lock, for example U- or Z.
  • -shaped filling elements are connected to the double T-shaped profile. In the latter case, essentially only the double-T-profiles serve as supporting elements, while the filling elements essentially have a sealing function.
  • club-shaped terminal connecting portions of the flange are usually designed by default in their geometry so that can be connected with each other or in combination with each other with just one connection lock all standard profiles.
  • a new sheet pile wall profile produced by means of hot rolling means the purchase of an expensive set of rolls at least for the finishing stand, increased stocking and high costs of test rolling until a quality-assured, salable product is available.
  • a mean value is given as a measure of the flange thickness, which results from the cross-sectional area of the flange divided by the total width of the profile.
  • the mean wall thickness corresponds to the nominal wall thickness in the flange section.
  • the average flange thickness determining opening dimension of the outer rollers of the finishing stand is increased in the millimeter range, so that over the resulting greater height of the profile a correspondingly increased average wall thickness is achieved in the flange.
  • the tolerances to be met in the connection area are relatively narrow. If the average wall thickness is increased too much, the lobe size becomes so great that the standard connection lock can no longer be pulled over the lobe.
  • the object of the invention is therefore to provide a sheet pile wall, with which the disadvantages described in the prior art can be avoided.
  • a double-T-shaped sheet pile profile is used to solve this task, in which the average wall thickness is increased in the flange at constant held club dimension of Ranendabiteses for a given standard profile, wherein increasing the average wall thickness in the course of one by hot rolling produced sheet pile profiles is produced.
  • the invention is also seen in a steel sheet piling profile produced by hot rolling in double T-shape with two flange sections connected centrally via a web with adjoining lobe-shaped terminal end sections for receiving connecting locks, wherein one or both flange sections are provided between the lobe-shaped connection end sections (e) - seen in cross-section - convexly bulged (are).
  • convex-like means an embodiment over which, for example, the bulge runs arcuately or rises in an arc shape and then drops again and extends linearly in the intermediate region or rises and falls again linearly and likewise extends linearly in the intermediate region.
  • the wall thickening according to the invention during hot rolling is preferably produced in the finishing stand, wherein the finish rolls for the external machining of at least one flange outer surface have a surface contour required for producing the wall thickening.
  • the wall thickening can be generated both on the flange outside and / or on the inside of the flange at one or both flange portions.
  • the wall thickening can be generated both in the available parallel and non-parallel flange sheet pile profiles available on the market.
  • the inventively produced during hot rolling wall thickening only the flange portion is about a further feature with a paragraph-free transition into the club-shaped terminal connection section over.
  • the heel-free transition consists of a conically tapering section and an arcuate section adjoining the connecting end section.
  • the surface contour of the wall thickening can be adapted in any shape to customer requirements. It is conceivable z. B. a substantially rectangular or concave or convex course of the surface contour.
  • the sheet pile wall profile produced according to the invention is only partially shown in cross section in the figure.
  • the sheet pile wall profile 1 consists of two centrally connected via a web 8 flange sections 3. At the flange sections 3, close to a club-shaped Anschlußendabête 4 for receiving connection locks, not shown here.
  • the outer contour of the flange portion of a hot-rolled standard sheet pile wall profile is marked by the dashed profile line 9, which extends substantially horizontally.
  • flange portions 3 The inside of the flange portions 3 is shown in this example as wedge-shaped tapering outward. However, it is also possible to produce parallel flange sections 3, to which the connecting end section 4 adjoins.
  • an increased wall thickness 2 limited to the flange section 3 is achieved by a corresponding calibration of the finish rolls during the hot rolling process.
  • This can be arranged according to the invention on one or both outer sides and / or on one or both inner sides of the flange portions 3.
  • the club-shaped terminal end section 4 has the original geometry of the standard profile, so that the standard connection lock can still be used.
  • the increased wall thickness 2 is only so great that the maximum profile height of the standard profile, characterized by the vertical distance of the club tips of the opposite flange halves, is not exceeded.
  • the increase in the wall thickness 2 can also be chosen larger with corresponding customer requirements.
  • the transition 5 from the increased wall thickness 2 to the club-shaped connection end section 4 is formed free of shoulders.
  • the surface contour of the increased wall thickness 2 is formed substantially horizontally, which merges with a conically extending portion 6 and an adjoining arcuate portion 7 in the terminal end portion 4.
  • the surface contour of the increased wall thickness 2 also have a sinusoidal, concave or convex course.
  • Double T-shaped sheet piling profile 2 increased wall thickness 3 flange 4 terminal end 5 paragraph-free transition 6 conical section 7 arcuate section 8th web 9 Profile line standard profile
