Definitions

  • the invention relates to a window frame formwork having a plurality of formwork elements, wherein the individual formwork elements are joined together to form a border of a window opening.
  • the invention relates to a window construction and a method for creating a building wall with a window opening and / or a window integrated in the window opening.
  • Window frame formworks are conventionally set up directly at the site of the construction site, by means of shuttering elements provided for this purpose, which are usually more or less sorted on construction sites, being manually fastened to a formwork wall. In this case, care must generally be taken that the formwork elements are attached as accurately as possible to the formwork wall.
  • window frame formwork or formwork elements cause time-consuming and costly reworking may be necessary because on the one hand in insufficiently closed window frame formwork introduced between the formwork walls filler, typically concrete, can penetrate into the interior of the window frame formwork and on the other, the entire orientation of the window frame formwork may be inaccurate, which must be applied at a later date balancing material or excess material must be removed in order to align the window to be installed at a later date exactly. It is customary to remove the shuttering elements used in the preparation of the window frame formwork again after curing of the filler, in which case the shuttering elements are often affected and, for example, wood residues can stick within the recess on the filler, which must be subsequently removed.
  • a window frame formwork of the type mentioned by the window frame formwork according to the invention comprises at least one fastening element with which the window frame formwork can be fastened to a shuttering wall.
  • Such a kind of window frame formwork is already delivered pre-assembled to the respective site, the individual formwork elements are already joined together to form the border of a window opening, eliminating the search for suitable formwork elements at the site and also an accurate alignment of the individual formwork elements to each other already in advance - eg in a supplier company - can be done.
  • the window frame formwork according to the invention has at least one fastening element with the aid of which the window frame formwork can be quickly and easily mounted on a shuttering wall.
  • the window frame formwork according to the invention can be dispensed in particular on a subsequent removal of the window frame formwork. Rather, the window frame formwork according to the invention can be used directly for receiving a window. This can be saved a lot of time, as a tedious and costly removal of shuttering elements of the window frame formwork can be completely eliminated. In addition, the time required during the installation of a window can be significantly reduced by the window frame formwork already tuned to the type of window to be installed or already prepared by the supplier.
  • the window frame formwork according to the invention can be mounted at the site of the construction site using the simplest means, for example only a hammer and nails.
  • a plurality of formwork elements means that three or more than three, in particular four formwork elements can be provided, in principle any geometric shapes can be created in. It would also be conceivable for the individual formwork elements to be made in one piece and to form a single formwork component In such a case, the individual would come Pages of such a formwork component the importance of a single formwork element in the context of the present invention.
