Definitions

  • the invention relates to a formwork element, in particular a formwork panel according to the preamble of patent claim 1 and a method for producing a formwork element according to the preamble of patent claim 12.
  • edge protection made of plastic which essentially serves to damage the edges of the formwork elements by a higher mechanical wear resistance of the edge protection made of plastic
  • edge portions of such formwork elements especially when constructing or dismantling a formwork construction, especially at the edges, exposed to high mechanical loads and thereby occurring damage to the edges adversely affect the quality of the concrete structures produced with the formwork elements, as characterized at joints between two formwork elements
  • edge damage protrusions or protrusions are caused on the finished component surface, which must be laboriously removed after disassembly of the formwork and therefore costly.
  • the freedom from damage to edges is therefore an important criterion for the service life of such formwork elements.
  • the edge protection made of plastic should also prevent moisture from penetrating over the edge surfaces of a formwork element, since the absorption or release of moisture can cause swelling or shrinkage of the body made of wood and / or wood material, since this is also on the surface quality of a so produced concrete component can adversely affect and beyond the mechanical strength of the formwork element due to degradation processes of the natural material wood, especially decay processes can be greatly accelerated, whereby the service life of a formwork element is also disadvantageously reduced.
  • edge cover layers have a central web projecting at right angles and engaging in an edge groove of the shuttering panels, and on the surface on which the edge cover layers bear against the wood core of the shuttering panel, the edge cover layers are glued to the wood core.
  • the wood core is provided to protect against moisture on the plate surface at least on one side with a flat cover layer of plastic and to prevent ingress of moisture into the wood core, the at least one cover layer in the region of their abutting surfaces at their outer edges with the adjoining edge layers glued or welded.
  • DE 26 18 366 A1 a formwork panel with a peripheral edge protection of elastically yielding material, which is firmly connected to the panel giving the button surface.
  • more elastic material can be arranged at the corners, in that the edge protection has a larger cross section in the area of the corners.
  • the edge protection slightly, about to protrude to about 0.5 mm above the actual formwork surface, so surveys are avoided on the finished concrete surface, but the edge protection is preferably formed flush with the formwork surface, since thereby at the joint two formwork panels gives only one sign.
  • DE 2 618 366 A1 shows in particular already the features of the preamble of claim 1.
  • the object of the invention is to provide a formwork element with an edge protection and a method for its production, in which, despite the use of economical manufacturing process high mechanical strength of the edge protection and a good protection against moisture penetration is achieved in the formwork element.

  • the main advantage of the elevations is that the corner regions of the formwork element do not jump back or recessed relative to the plate surface of the body and thus no local elevations arise on the finished concrete surface, even if in use the body increases in its thickness due to the influence of moisture in its thickness by swelling processes or the corner areas as the most heavily loaded zones of the formwork element have a greater wear than the main body or the first guard edge portions.
  • a further advantage of the cantilever sections is that with stacking elements formed in such a way air gaps between facing plate surfaces are formed, which facilitate a venting moisture from the body over the plate surfaces and thereby waterlogging and the corresponding negative and Lebensdauerverkürzenden effects on the wood or the wood materials of the formwork element are reduced.
  • the cantilever portion is in particular raised between 0.5 mm and 2 mm with respect to the plate surface of the formwork element.
  • the protective edge in the corner sections has a greater thickness, which causes better damping and cushioning of shocks and at the corners impinging shocks are distributed over a larger area of the edge surface, whereby a correspondingly lower risk of damage to the Basic body is given.
  • the thickness of the protective edge may be greater than 15 mm in the corner regions measured from the edge surface to the corner.
