Definitions

  • the invention relates to an anchor system of a concrete wall formwork with at least one locking device for an anchor rod of the anchor system, wherein the locking device has a nut element for screwing through the anchor rod by a nut thread of the nut member.
  • Such anchor systems are used in formwork technology in concreting reinforced concrete structures.
  • Concrete wall formworks are made of a formwork skin and its supporting elements, e.g. Side member and cross bar, constructed.
  • the two sides of a wall are each made up of a concrete formwork element, i. a formwork half, formed, which are held together by anchor rods.
  • the anchor rods are inserted through holes in the formwork skin and attached at their ends to the formwork supporting the elements so that the force acting on the anchor rods during concreting tensile force is absorbed.
  • the two ends of the anchor rods have threads on which nuts are screwed as Ankerfix isten. As a result, the effective length of the anchor rod and thus the strength (thickness) of the wall to be concreted is determined.
  • the pressure exerted on the formwork by the liquid concrete during concreting is dissipated via the nuts on the tie rods.
  • the tie rods are loaded on train. Spacers are inserted between the shell skins in the volume of the wall to be concreted, which can accommodate the pressure forces generated during the concreting process, thereby ensuring that these compressive forces do not affect the wall thickness undesirable, i. Reduce.
  • DE 197 54 366 C2 discloses an anchor system of a concrete wall formwork in which a locking device is provided on one side of a Beto ⁇ wandschalung.
  • the locking device consists of a positional fixation of a nut of the anchor system.
  • the nut is fixed in position by transverse to its axis, fixed in a cross bar locking screws, whereby the position-fixed nut is no longer rotatable.
  • the screw is also locked relative to a formwork half due to the fastening of the locking screws on the crossbar.
  • DE 103 36 414 B4 discloses an anchor system, wherein in each case a very flexible locking device is provided on the backs of two forming a concrete wall formwork formwork elements through which an anchor rod of the anchor system, by means of which both train and compressive forces are absorbed on the formwork elements can ensure that the concrete wall thickness to be formed can be formed very accurately.
  • DE 94 12 556 discloses a locking device for an anchor rod of an anchor system of a concrete wall formwork, with a nut member for screwing through the anchor rod, wherein a dome plate is provided, which has a spherically shaped plate portion with an opening.
  • the nut member is formed to be spherical so as to be movably supported within the edges of the opening similarly to a ball joint, whereby radial rotation of the nut member in the opening is prevented by axial groove-like guides.

  • the dome plate has a spherically shaped plate portion with an opening in which the nut member is arranged with radial play.
  • the nut member has a groove-like radial circumferential receptacle in which the edges of the opening are received in the spherical plate area.
  • the radial clearance is circumferentially present, so that within the radial play a full deflection of the nut member on the dome plate is made possible. This results in a fulcrum of the preferably a dome nut comprehensive nut element in the region of the armature feedthrough bore in the formwork skin.
  • the radius of the spherical plate area is chosen according to the distance between the formwork skin and the opening in the spherical plate area. The nut element can thus be deflected similar to a joystick on the dome plate.
  • end of the screw nut element is provided with the nut thread of the screw nut element aligned, tubular guide means.
  • the tubular guide means may be advantageously formed funnel-shaped.
  • at least the cross section of the screw nut element facing away from the opening of the guide device exceeds that of the nut thread of the nut member.
  • the guide device ends in the region of the scarf skin level, so that the tip of an anchor rod compellingly enters the opening of the guide device when setting an anchor rod.
