Definitions

  • the invention relates to a quick connector for the end fastening of a continuous reinforcement iron on a vertically oriented cast-in dowel radial expansion at the end.
  • Socket anchors are used as interlayer connectors with one, preferably with Reaction resin mortar fastened in a blind hole in the old concrete, fastening part and Embedding part later embeddable in new concrete.
  • the end of the cast-in dowels has radial widenings, for example conical widenings a piece of pipe designed as a pouring dowel.
  • US3163266 is used as a quick connector for one-handed installation of two vertically a resilient wire bracket that is oriented towards each other and consistently of light profiles used, which has a primary turning bend of 150 ° in the middle and its legs each have a secondary turn of 180 ° perpendicular to it.
  • the Secondary turning bends serve as a form-fitting hook for one Light profile, which are angled at 90 ° in the height of the light profile together with a slightly cranked primary turning bend as a clip-on hook trained, which engages behind the width of the light profile.
  • US4388791 is a quick connector for one-handed installation of two vertically a resilient wire bracket that is oriented towards each other and in each case continuous reinforcing iron used, which has a primary turning bend of 180 ° in the middle and its parallel running legs each have a secondary turning bend of 120 ° perpendicular thereto have, which can be clipped over the reinforcing iron and this perpendicular to the other reinforcing bars fixed with a positive fit.
  • An end fixation is only conditionally possible.
  • the task is to implement a detachable quick connector for the end Fastening of a continuous reinforcing iron to a casting anchor.
  • Another Aspect consists of a variant that can be assembled with one hand.
  • the wire bracket designed as a quick connector consists of a bent piece of wire made of at least partially resilient metal between 2 and 8 mm diameter, the wire bracket with respect to one, for one-sided reception of the Molded dowels, half length with a radius greater than or equal to not radially widened diameter of an associated cast-in dowel, Primary turning between 90 ° and 180 ° with mirror symmetry to the bisector Is designed flat legs, each leg one, for one-sided Recording an associated reinforcing iron trained, substantially perpendicular for the primary turning bend, the secondary turning bend is between 90 ° and 360 °, with a radius greater than or equal to the diameter of the reinforcing iron and in each case one end, bent essentially perpendicular to the primary turning bend, in Angle between 30 ° and 90 ° angled, clip-on hook is formed, which in the radially outer end region of the radial expansion at the end of the casting anchor is designed to be non-positive.
  • the pouring dowel is in the non-radially expanded part of the primary turn of the Wire bracket can be gripped radially on one side.
  • the clip-in hooks of the legs spring into the radial expansion at the end detachable. Due to the radial expansion of the casting anchor clip-in hook of each leg and that, the not radially expanded part of the
  • the wire bracket is a three-point primary turning bend securely fixed at the end of the cast-in dowel. Between the radial this is the expanded part of the cast-in dowel and the two secondary turning bends continuous reinforcing bars securely fixed with a positive fit.
  • the secondary turning bend is advantageously between 90 ° and 180 °, as a result of which continuous reinforcing irons can be inserted radially on one side.
  • the tertiary turn parallel to the primary turn is advantageous, further advantageous in Direction to the plane of symmetry, curved, whereby the reinforcing iron per leg additionally abuts the tertiary leg and the wire bracket is compact.
  • the wire bracket 1 designed as a quick connector consists of a bent wire piece of diameter D and length L.
  • Each leg 5, 5 ' is one end, perpendicular to the primary turning bend 3 and perpendicular to Secondary turning bend 6, 6 'bent, at an angle of 90 ° in the direction of Angle bisecting plane 4 angled, clipped hook 8, 8 'formed, which non-positively in a radially outer end region 9 of a conical end radial expansion 10 of the dowel 2 is compressed.
  • Each leg 5, 5 ' is the end, perpendicular to the primary turning bend 3 and parallel to the secondary turning bend 6, 6 'curved, clip-in hook 8, 8' formed at an angle of 60 °, which is non-positive in the radially outer end region 9 of the conical end radial expansion 10 of the dowel 2 is compressed.
