Definitions

  • the invention relates to a formwork system with shuttering elements having opposite formwork inner surfaces, which are mutually connected by means of formwork anchors spaced apart, wherein a formwork anchor consists of a bolt element and two locking elements, which in the two opposite end portions of the bolt element coupled thereto and for transmitting tensile forces of the formwork elements are formed on the bolt element.
  • Such formwork systems are known from the prior art in various embodiments. They are used on construction sites of various sizes to define limited volumes in the construction of reinforced concrete frameworks by formwork surfaces or by an inner and an outer formwork, which are then filled with liquid concrete. After solidification of the concrete, the formwork elements are then removed again, whereupon they are usually reusable for the construction of other formwork.
