Definitions

  • the invention relates to a stop holder with a stop for a wall formwork for erecting a concrete wall on a concrete base, the stop holder being able to be fixed to an upright reinforcing connecting iron by means of a fixing means.

  • a clamping device for fixing a spacer designed as a crossbar with end stops is known.
  • the spacer When erecting a double-sided wall formwork, the spacer is used to set a defined distance between two formwork walls braced against the end stops.
  • the known clamping device consists of a U-shaped profile piece, on the front side of which two diametrically opposite recesses are provided for inserting the spacer.
  • the profile piece is placed on the connecting iron and the spacer is inserted into the recesses. After aligning the spacer on a guide line, a wedge is driven in to fix it between the spacer and the connecting iron.
  • spacers connect the two formwork walls of a two-sided wall formwork to one another, ie the spacers are continuous from wall to wall.
  • the spacers are continuous from wall to wall.
  • the inventor has set himself the task of creating a stop holder of the type mentioned at the outset which, with simple handling, enables rapid setting with a high level of accuracy.
  • the stop bracket should also be used to create watertight concrete walls.
  • a first solution to the task according to the invention is that the stop holder has a receiving opening for the connecting iron and can be rotated about the axis of the connecting iron before it is fixed, the stop being designed as a curved stop surface with a constantly changing distance from the axis of the connecting iron.
  • the stop is integrated in the stop holder according to the invention, ie the part to be fixed to the connecting iron is provided directly with a stop.
  • a two-part arrangement is obtained which, by simply rotating the stop holder, enables the stop to be precisely aligned with the guide line.
  • the stop holder according to the invention is no longer continuous from wall to wall, but instead forms an individual stop to the adjacent formwork wall. As a result, in contrast to conventional spacers, water penetrating along the stop holder can only penetrate the concrete wall to a minor extent and in particular can no longer penetrate it completely. Accordingly, the stop bracket according to the invention is also suitable for the construction of watertight concrete walls.
  • the stop holder according to the invention can also be used without problems where a circumferential rubber band is used to prevent seepage water from penetrating the floor of the wall to be created.
  • the curvature of the stop surface is circular or elliptical.
  • the ellipse shape results in a greater variation of the setting options for the stop distance.
  • the axis of the connecting iron lies eccentrically to the cylinder axis.
  • it can lie both in an ellipse axis and eccentrically to it.
  • Well-known means can be used as fixing means for fixing the stop holder to a connecting iron, e.g. a set screw that braces the stop bracket against the connecting iron.
  • the receiving opening for the connecting iron is designed as an undercut groove for receiving a wedge element which can be driven in between the connecting iron and the mating surface of the groove.
  • the stop holder can, for example, be made in one piece from metal or from a possibly fiber-reinforced plastic.
  • the stop holder consists of a stop part which has the stop surface and a fastening part which is rigidly connected to it and has the undercut groove.
  • the fastening part is designed as a profile piece with a substantially U-shaped cross-section, the free ends of the U-legs being angled inwards to form the counter surfaces.
  • the U-legs can have one or more kinks.
