Definitions

  • the invention relates to a tubular steel frame with tube stands on which these flange-like brackets are fastened at a distance from one another, to which the bars of the frame can be connected by means of claws fastened to the bars at the ends and with which the bars can be locked by wedges, the wedges in openings in the shafts of the claws can be driven in from above and in the driven state are supported with their one wedge surface on an inclined surface of the openings.
  • the invention has for its object to improve the wedge connection of the bolts with the brackets of the tubular stand of the tubular steel frame.
  • the object of the invention is that the jacket of each console has a conical surface that extends over the circumference of the jacket and tapers downwards, on which the wedge is supported with its other wedge surface in the driven state. The wedge partially engages under the console.
  • the wedge connection according to the invention is progressive over the known wedge connection in that it not only provides a non-positive, but also a positive connection of a bolt to the brackets of two pipe stands with the advantageous effect that unintentional loosening of the bolt from the brackets is avoided with certainty . This applies even in the event that the wedge is not driven in firmly, but falls into the locking position due to its heavy weight.
  • each bracket has a circular collar which surrounds the tubular stand at a distance and which is trapezoidally tapered at the top in cross section, and that the jaws of the claws are correspondingly trapezoidal on the inside and are designed in accordance with the curvature of the collar .
  • the console according to the invention also offers the advantage that the latch can be connected at any angle.
  • a steel tube frame has become known from German Offenlegungsschrift 26 58 410, in which the bars with their claws can be pushed onto annular, perforated brackets provided on the tube frames of the frame.
  • the jaws of the claws have mutually corresponding openings for receiving a wedge, which penetrates an opening in the console when it is driven into the openings.
  • the claws are clamped with the free ends of their jaws to the casing of the pipe stand in order to produce a positive and non-positive connection of the bolts with the pipe stand.
  • the console 2 has a circular arrangement, as passages for rainwater, dirt or the like. serving breakthroughs 3 and a collar 4 enclosing the tube stand 1 at a distance, which is integral with the bracket 2.
  • the collar 4 is tapered in a trapezoidal cross section at the top.
  • the jacket of the console 2 has a conical surface 5 which extends over the circumference of the jacket. 6 with a horizontal tubular bolt is designated, which carries a claw 7 at its ends. The claw 7 is fastened with a shaft 8 in the bolt 6.
  • the jaws of the claw 7 are designed on the inside in accordance with the curvature and the trapezoidal taper of the collar 4 of the bracket 2.
  • the latch 6 is firmly pushed onto the collar 4 of the bracket 2 by the claw 7.
  • the shaft 8 of the claw 7 has an opening 9 which serves to receive an elongated wedge 10.
  • the wedge 10 is supported in its effective position with its one wedge surface on an inclined surface 11 of the opening 9 and with its other wedge surface on the cone surface 5 of the casing of the bracket 2.
  • the wedge 10 is expediently captively connected to the claw 7.
