Definitions

  • the invention relates to a formwork anchor receptacle for a concrete formwork anchor in a concrete formwork element, a concrete formwork element and a method for producing a concrete formwork according to the preamble of the independent claims.
  • Formwork anchors for concrete formwork are already known in the art, which serve to hold the position of the wall formworks when filling the gap between the formwork with concrete.
  • anchor nuts are arranged on a formwork anchor on both sides. This anchor rod is removed after curing of the concrete in the space between the two wall formwork again.
  • these formwork anchors are fixedly provided in the formwork elements, so that special formwork elements are necessary, if access to the anchorage from only one side, is possible.
  • a first formwork wall is first positioned, the setting formwork.
  • the second formwork wall is referred to as Schlischschalung.
  • Usually access from both sides of the formwork is possible, so that the anchoring nuts can be easily fastened from both sides.
  • a disadvantage of this design is the very complicated and complex construction and the need to use special formwork elements to a special formwork anchors to fix in the concrete formwork at all. This leads to very high construction costs.
  • a formwork anchor receptacle for a concrete formwork anchor which comprises an anchor thread for receiving a formwork anchor with an anchor thread longitudinal axis. Furthermore, the formwork anchor receptacle comprises a fastening element for releasably securing the formwork anchor receptacle to a formwork element, so that an axial displacement along the armature thread longitudinal axis can be prevented by positive locking.
  • the formwork anchor receptacle further comprises an anti-rotation device for preventing rotation of the formwork anchor receptacle when attaching the formwork anchor, wherein the fastening element is designed such that it can be brought into engagement with transverse and / or longitudinal struts and / or openings in a transverse strut or longitudinal strut of the formwork element.
  • Such a formwork anchor receptacle can be easily attached to an existing concrete formwork element and thus enables unilateral anchoring with standard concrete formwork elements.
  • a positive fit is understood to mean that only a form fit is present.
  • a thread in Ankergewindelijnsachseoplasty is not understood under positive locking.
  • the rotation and the fastener may be separate elements.
  • the anti-rotation device can comprise an anti-rotation opening, in particular a slot, into which the fastening element can be introduced.
  • the fastening element can in particular be introduced into the opening in such a way that an insertion direction of the fastening element differs from the direction of the armature thread longitudinal axis.

  • the access of the setting formwork, arranged on the formwork anchor receiving element is no longer possible, a secure attachment of the fastener is useful.
  • the fastening element is preferably designed such that it can be easily inserted through the anti-rotation opening and in a locking position slip out or make it impossible.
  • a bolt element is provided with a slot which is coaxial with the fastener inserted and thereafter at a different angle, in particular substantially vertically fixed.
  • the rotation in particular a contact surface of the rotation, which can be applied to a formwork element, in particular to a cross member of a formwork element, can be formed substantially parallel to the armature thread longitudinal axis.
  • the contact surface may be formed substantially at the same height with the armature thread longitudinal axis or it may be formed a distance B between the anchor thread longitudinal axis and contact surface.
  • the distance B is the minimum perpendicular distance between a projection of the anchor thread longitudinal axis and the contact surface.
  • the fastener may be captively attached to the formwork anchor receptacle.
  • the minimum distance from the armature thread longitudinal axis perpendicular to the anchor thread longitudinal axis and the opening may be 70mm to 160mm, preferably 75mm to 100mm, more preferably 80-85mm.
  • the fastening element may comprise a bolt which can be introduced into an opening of a formwork element.
  • a bolt is easy to produce and fits optimally in the opening of a formwork element.
  • the fastener can be easily and inexpensively.
  • the fastening element can be designed in such a way that it can be brought into engagement with the anti-twist device and a concrete formwork element at the same time.
  • the formwork anchor receptacle may have a thread for receiving the anchor rod, wherein the thread has a stop for the anchor rod.
  • the stop may be, for example, a separate stop behind the thread, so that additionally by visual inspection, the position of the anchor rod can be controlled.
  • the stopper may be formed by a soldering point or the like on the thread.
  • a formwork element having at least one formwork anchor opening, in particular a formwork anchor opening in a longitudinal strut, and preferably an opening in a longitudinal or transverse strut, wherein the opening in the longitudinal or transverse strut is arranged substantially perpendicular to the formwork anchor opening.
  • a formwork anchor receptacle as previously described can be brought into engagement with the formwork element.
  • the arrangement of the openings is such that in each case the longitudinal axis of the opening in the longitudinal or transverse strut and the longitudinal axis of the shuttering anchor opening, ie in the case of round openings, the central axis of the round opening are arranged substantially perpendicular to each other.
  • a concrete formwork element can be produced from a standard formwork element with the aid of the formwork anchor receptacle for anchoring that can be operated on one side. If the same concrete formwork element Afterwards it should be used again as an accessible closing formwork, the formwork anchor receptacle can be easily dismantled again.
  • the fastener can fix the anti-rotation in its engaged position, in particular, the fastener through an opening in the rotation and through an opening in a strut of the formwork element, preferably an opening in a cross member of the Concrete formwork element, be attached.

  • the distance C is 125.5mm or 140mm, depending on whether it is a large formwork element or a normal formwork element.
  • the formwork anchor receptacle can be easily attached to a standard concrete formwork element, if a one-sided operation anchoring is desired. If two-sided anchoring should be possible, the formwork anchor receptacle can be easily removed again from the concrete formwork element, and thus the concrete formwork element can be used as before.
  • the concrete formwork element can be positioned after fixing the formwork anchor receptacle as an adjustment formwork.
  • the formwork anchor receptacle is attached to the concrete formwork element prior to positioning the concrete formwork element to allow unilateral operable anchoring, since access after positioning as an adjustment formwork can be difficult.
