Definitions

  • the invention relates to a component, in particular for windows or conservatories.
  • the component has an elongated shape and is intended to assume a supporting function when installed.
  • the component comprises a wood core and a cover layer for protection against wood-damaging influences, wherein the cover layer covers at least a part of the surface of the wood core.
  • Wood is widely used as a building material for windows and conservatories, because it offers good stability and is easy to work with. Basically, wood also has a good durability, but this can be significantly reduced if the wood is exposed to wood-damaging influences.
  • wood-damaging influences can, for example, weather influences, under which the wood becomes moist and thereby rots. The climate can be similarly damaging in swimming pools, where the wood is exposed to a damp heat. Damage to the wood can also be caused by chemical influences and air pollutants.
  • a common solution is to cover the portions of the surface of the wood core exposed to wood-damaging effects with an aluminum sheet.
  • the aluminum sheet keeps the wood-damaging influences from the wood.
  • it is felt in this solution as disadvantageous that the aluminum sheet determines the visual appearance of the device. Instead of the impression of a wooden part, the impression of a metal-made component is conveyed.
  • the wood core is usually covered with a thin aluminum sheet as possible.
  • the thin aluminum sheets protect from the wood-damaging influences, but have the disadvantage that they are sensitive to mechanical stress. Local application of pressure or light impact may cause dents in the surface which are not easy to remove.
  • the invention is based on the object to present a component according to the preamble of claim 1, which is protected against wood-damaging influences and avoids the disadvantages mentioned.
  • the object is solved by the features of claim 1.
  • Advantageous embodiments can be found in the subclaims.
  • the cover layer consists of a wood that is resistant due to thermal or chemical treatment.
  • thermal and / or chemical treatment is meant no surface-limited treatment.
  • the treatment rather covers the entire structure of the wood.
  • the top layer thus consists of a wood that is resistant to wood damage after treatment. As a result of the treatment, the wood of the top layer may have lost some of its load-bearing capacity, so that it is unsuitable for independent use in a load-bearing function.
  • the component according to the invention has the advantage that it combines a good resistance to wood-damaging influences with the visual impression of a wooden component.
  • the component also has a surface that withstands mechanical effects well.
  • the components are usually assembled at right angles.
  • the components fit particularly well in such an environment if the wood core has a rectangular cross-section. Since the Wood core takes over the supporting function of the component, it is crucial that this can border at right angles to the surrounding components of the building.
  • the cover layer can supplement the cross section of the wood core in the form that the component as a whole also has a rectangular cross section.
  • the cover layer can also have a different cross-section.
  • the component may for example be part of a wall in which it adjoins with its lateral surfaces and the end faces of other components of the wall.
  • the inside points to a room interior, only the outside is exposed to the weather. In such a case, it may be sufficient to cover only a first of the longitudinally extending surfaces of the device with a cover layer.
  • the components are installed in such a way that the surface facing the outside projecting from the surrounding components of the structure, for example when the component is part of a window frame.
  • the lateral surfaces as far as they project from the surrounding components, must be protected against wood-damaging influences.
  • An aluminum sheet could be folded in this case at the boundaries of the outer surface, so that it also covers the side surface. This possibility does not exist with a cover layer of wood.
  • a cover layer of wood that corresponds to the folded aluminum sheet would have to be made of several parts. However, this is expensive.
  • the cover layer is so thick that the projecting Part of the device is completely formed by the cover layer. Both the outwardly facing surface and the faces facing the sides, insofar as they are exposed to wood-damaging influences, are then parts of the cover layer attached to a surface of the wood core. Despite its projection against surrounding components of the structure, the device is protected in this way with only one cover layer.
  • the ratio of the thickness of the cover layer to the thickness of the wood core is preferably greater than 0.3, more preferably greater than 0.5, more preferably greater than 0.7.
  • the strength of the wood core is the thickness in the direction in which the cover layer is applied to the wood core.
  • the component may be exposed to wood-damaging influences in more than one direction.
  • all surfaces of the wood core where this proves necessary, be covered with the cover layer.
  • the cover layer can cover the wood core completely to all sides.
  • the device is installed so that it is exposed to wood damage in two directions.
  • a second of the surfaces extending in the longitudinal direction of the component may be covered with a cover layer.
  • the two surfaces which require a cover layer face each other. This case may, for example, occur in the wall of a swimming pool, where the component is exposed to the outside of the weather and to the inside of the warm and humid air of the swimming pool.
  • the component If used as a corner element, it can be exposed to wood damage with two adjacent surfaces.
  • the two surfaces covered with a cover layer can lie side by side under these conditions.
  • the wood core preferably has a material thickness of at least 4 cm and is more preferably constructed of several layers.
  • wood species for the wood core are especially larch, Meranti or Hemlock into consideration.
  • the cover layer is preferably between 2 cm and 4 cm, more preferably between 2.5 cm and 3 cm thick.
  • the wood of the topcoat may have been rendered resistant by any thermal and / or chemical treatments.
  • the treatment comprises the step of exposing the wood to a water bath under elevated pressure at a temperature between 150 ° C and 180 ° C.
  • Another advantageous method step is to heat the wood of the cover layer in a dry environment to a temperature between 150 ° C and 180 ° C.
  • the wood supplied by Plato International BV (Arnhem, The Netherlands) has proven to be suitable for the top layer.
  • a wall 3 in Fig. 1 separates a protected interior from an outdoor space exposed to the weather.
  • a component which comprises a wood core 1 and a cover layer 2.
  • the wood core 1 which can be composed of several layers of wood, is the supporting element of the component, which ensures the stability.
  • Over two surfaces 6 of the wood core 1 is a firm connection between the wood core 1 and the wall.
  • the cover layer 2 is glued to the wood core 1 and covers a surface 4 of the wood core 1 pointing in the direction of the outside space.
  • the cover layer 2 is made of a wood which is treated thermally and / or chemically in such a way that it is resistant to the wood-damaging influences of the wood Weather is.
  • the cover layer 2 is flush with the wall 3 from.
  • the joints between the cover layer 2 and the wall 3 are sealed, so that the wood core 1 is completely protected from the weather.
  • With its further surface 5, the wood core 1 directly adjoins the interior. In the interior there is a dry room climate, so that the surface 5 of the wood core 1 is not exposed to wood-damaging influences.
  • the component consisting of the wood core 1 and the cover layer 2 projects relative to the wall 3.
  • the cover layer 2 is so thick that it forms the entire part of the component projecting over the wall 3.
  • the joints between the cover layer 2 and the wall 3 are sealed, so that the wood core 1 is protected.
  • the wood core 1 borders on an interior which is free of wood-damaging influences.
  • the component is installed as a corner element.
  • the two outwardly facing surfaces 4, 7 of the wood core 1 are covered with a cover layer 2 composed of two parts.
  • Fig. 4 the device is exposed on both sides of the wall 3 wood-damaging influences.
  • the weather affects the component, on the inside, the moist-warm air of a swimming pool.
  • Both surfaces 4, 5 of the wood core 1 are covered with a cover layer 2, which provides protection against the wood-damaging influences.
  • the remote from the wood core 1 edges of the cover layer 2 are rounded.
  • the combination of wood core 1 and cover layer 2, the device of the invention combines various advantages.
  • the normal wood used for the core 1 is inexpensive and provides sufficient stability even for load-bearing parts.
  • the cover layer 2 of a wood material resistant to treatment, the wood core 1 is protected against wood-damaging influences.
  • the cover layer 2 offers by its wooden surface an attractive appearance and a good resistance to mechanical effects.
