Definitions

  • the present invention relates to a connection for steel profiles with any cross section, consisting of two opposite end faces, which are inextricably linked.
  • this object is achieved in that the mutually opposite ends of the steel profiles are jointly encased on the outside or inside by a sleeve, in that the opposite surfaces of the steel profiles and the sleeve, which form an intermediate space, are roughened and in that the intermediate space is filled with grout , which may be injected at high pressure.
  • the object can also be achieved in that one of the opposite ends of the steel profiles is surrounded on the outside or inside by one end of a sleeve, and in that the sleeve is firmly connected at its other end to the end face of one steel profile in that the mutually opposite ones in the overlap area and between the surfaces of the steel profile and the sleeve that form an intermediate space are roughened, and that the intermediate space is filled with grout, which may be injected at high pressure.
  • the roughened surfaces of the steel profiles and sleeve prefferably be designed in such a way that the surfaces have ribs, beads or grooves with a rectangular or trapezoidal cross section.
  • the ribs or beads can simply be welded on or the grooves turned (for round profiles) or milled. They significantly increase the strength of the connection. It is also advantageous to apply seals in the region of the ends of the sleeve, since this prevents the grout from escaping.
  • profile and sleeve are biased in the joint area in particular in the case of pipes by the high-pressure injection in such a way that the profile in the direction of the start Pressure and the cuff train receives, and that the injection mortar is under all-round pressure. This means that, for example, the outer profiles or the outer sleeve cannot come off in the event of sudden warming.

  • the connection of the steel pipes 1 'and 2' with the help of the outer sleeve 3 and possibly the mounting sleeve 10 is made by high-strength grout 11.
  • the grout 11 is through a grout 12 in the outer sleeve 3 in the space 13, which is between the steel pipes 1 'and 2' and the outer sleeve 3 is pressed in until it completely fills it and further penetrates into the gap 8 between the end faces 6 and 7 of the steel tube 1 'and 2'.
  • the grout 11 is at the outflow from the space 13 at the two ends 14, 15 of the sleeve 3 through seals 16 and 17 arranged there between the steel pipes 1 'and 2' and the outer sleeve 3 and through the seal 17 between the mounting sleeve 10 and the steel pipe 2 hindered.
  • the inside 18 of the outer sleeve 3 and the outside 19 and 20 of the steel tubes 1 'and 2' can be profiled in the overlap area 21 of the sleeve 3, as shown in FIG. 1 by the detail X shown enlarged.

  • Figure 2 shows a variant in which the end faces 6 and 7 of the steel pipes 1 'and 2' lie directly on top of each other and no grout 11 gets into the interior 9. Due to the direct contact of the end faces 6 and 7 of the steel pipes 1 'and 2', this variant has a higher load-bearing capacity for longitudinal pressures. It is also suitable for full profiles.
