Definitions

  • the invention relates to a laminated wooden profile strip for creating blind and / or casement frames in the manufacture of windows, doors or the like surfaces that extend approximately perpendicular to the glued surfaces are reworked to size by milling.
  • the invention also encompasses a method for producing a laminated wooden profile strip, in which a plurality of lamellae are connected to one another by gluing and the final profile cross section is reworked by milling.
  • wooden profile strips are used, from which sections are formed by miter cuts and assembled into frames.
  • a window is a technical component, the requirements for dimensional accuracy, stability and surface appearance have increased significantly. So z. B. the demand for free of knots in the surface of windows made of profiled strips made of solid wood - especially when using softwood - by the use of the best and therefore expensive wood qualities.
  • Laminated wooden profile strips also called scantlings, are therefore known, which are composed of several solid wood slats.
  • the lamellae each have a rectangular cross-section, for example in the form of a narrow board, and are connected to one another by gluing, the glued surfaces being in the main extension planes of the lamellae.
  • Laminated Wooden window profiles "of the Wood Information Service of the Wood Working Group are such wooden profile strips of the type described above with all the advantages and disadvantages, requirements and properties described.
  • the slats sometimes called board paper, consist of solid wood with a cross section suitable for the cross section of the wooden profile strip to be created. As a rule, at least three lamellas are joined to form a wooden profile strip.
  • the slats are either rectangular or in L, T or Z shape placed on top of each other and glued together. A milling process is then carried out on all four sides of the wooden profile strip in order to achieve the required dimensional accuracy of the wooden profile strip. Milling on all four sides of the wooden profile strip results in considerable waste. Milling on the two surfaces of the wooden profile strip, which lie parallel to the main planes of the slats, is necessary because the slats can only be produced with relatively large tolerances by planing. With such wooden profile strips there are specified requirements for the slats on the one hand, the structure of the Cross-section of the wooden profile strips, the surface appearance and the technical properties.
  • the structure of the cross section of the wooden profile strips should be symmetrical and the wood structure of the individual slats should be the same.
  • the outer slats should be of the same thickness and consist of one type of wood. In particular, pine, spruce, larch, Douglas fir, to a small extent also oak and the tropical woods Meranti, mahogany etc. are used.
  • the slats are glued with thermoplastic glues, which should also be weatherproof. However, the glue joint should not be exposed to direct external weathering. As a result, the glue joint must run parallel to the main plane of the window.
  • the outer slats should be at least 15 mm thick.
  • the lamellae must be of such a nature and arrangement to one another that a risk of tearing is avoided.
  • a freedom from warping can only be achieved to a limited extent because the lamellas as solid wood are a natural material, i.e. not a wood material. It must on the different loads of wooden moldings on windows such. B. on the outside relative to the room side. If, for design reasons, it cannot be avoided to reveal the glue joint to the outside weathering, then the gluing must be carried out using resorcinol resin glue. Otherwise, polyvinyl acetates are sufficient as glues, which must correspond to stress group B4 according to DIN.
  • the glue joint can be prepared on the slats as planed smooth surfaces.
  • a tine or wave shape is also permissible, which of course requires additional processing.
  • any annual ring position is possible. However, this should be uniform within a wooden profile strip, i.e. not different. This is necessary to ensure dimensional stability and to avoid stress cracks.
  • chipboard has been known for a long time. These represent the typical wood material, in which wood chips are glued together, so that a largely homogeneous material is created within the layering.
  • phenolic resin-glued chipboards are, for example, hydrophilic and therefore not suitable for outdoor use.
  • wooden profile strips are used in furniture construction.
  • Isocyanate glued chipboard are used indoors, e.g. B. used in the creation of a floor, for cladding purposes in the bathroom or even once as the weathering not directly exposed roof formwork. Chipboards with special quality requirements are still permitted for the outer skin of walls of prefabricated houses if weather protection is applied there. Such weather protection consists of a facing made of plaster, clinker or the like. From this it can be seen that it has not been possible to date to build a window made of a wood-based material that is usually accessible to external weathering. The known inadequate dimensional stability of wood chipboard under the influence of moisture represents an obstacle here.
  • a cuboid wooden body for working out wooden components is known from EP 0 320 803 A2.
  • the cuboid wooden body is produced by gluing several wood fiber boards together over the entire surface. From this stack of panels, individual wooden components can then be worked out, such as are useful, for example, for mold, model and fixture construction. It is also possible to work out and use casements for doors made of this material. Load-bearing components can also be produced in this way, whereby considerable waste must be expected in each case.
  • the invention has for its object to provide wooden profiles for the creation of frames in the manufacture of Windows, doors or the like are suitable to show that can be manufactured more easily than before.
  • slats consist of strips of isocyanate-glued, medium-density fiberboard (MDF).
  • MDF medium-density fiberboard
  • a wood preservative can also be incorporated homogeneously in the manufacture of the MDF boards in a simple manner.
  • the frames on windows, doors or the like created from such wooden profile strips are surprisingly weatherproof. While wood-based materials have been known for decades, no windows have yet been created from them. This technical misconception can be remedied with isocyanate-glued MDF boards.
  • waste wood in particular industrial waste wood
  • waste wood can also be used to produce the lamellae from the medium-density fiberboard, from which a high-quality product is readily produced.
  • the entire problems of knot-free, flawlessness, wood structure etc., as they occur with wooden profile strips made of solid wood lamellas, are eliminated.
  • Slats made from strips of isocyanate-glued MDF boards and the wooden profile strips created from them have a long-term dimensional stability.
  • the wooden profile strips can also be easily produced in large lengths, for example as profile strips in lengths of 5 or 6 m.
  • the arrangement of longitudinal joints is eliminated.
  • the new wooden profile strip is not only suitable for the creation of wooden windows, but also for the creation of wood / aluminum construction elements.
  • the wooden profile strip can at least on its essential surface with a coating, planking o. B. be surrounded by a plastic film.
  • This surface protection is advantageously applied at the factory after the lamellas have been glued and thus mitred before the wooden profile strip is cut. This eliminates the need for surface processing in the companies involved in the production of windows, doors or the like.
  • the process for producing a laminated wooden profile strip is characterized according to the invention in that the lamellae are cut from strips of isocyanate-glued, sanded, medium-density fiberboard (MDF), and in that the milling only on the mutually opposite surfaces extending perpendicular to the sanded surfaces he follows.
  • MDF medium-density fiberboard
  • the slats can advantageously be cut with a lower tolerance than solid wood, which further reduces waste.
  • the wooden profile strip can be provided with a coating, planking or the like before it is cut to frame profile sections. This also simplifies the manufacture of the windows as a whole.
  • the essence of the invention is the use of isocyanate-glued medium-density fiberboard (MDF) as lamellas for wooden profile strips for the production of windows, doors or the like.
  • MDF medium-density fiberboard
  • Medium-density fiberboard 1 for example in the dimensions 5 m x 2.5 m, the two surfaces of which lie in the main extension planes are ground true to size, are cut into strips, so that lamellae 2 result from this.
  • the width of the slats 2 can vary depending on the requirement and cross-sectional structure of the wooden profile strip.
  • Several such lamellae 2 are joined together to form a raw scantling 3, adhesive bonding to glue joints 4 taking place.
  • the raw edge 3 is already dimensionally accurate in the area of its two surfaces, which are parallel to the glue joints 4.
  • the raw shell 3 here has a Z-shaped cross section.
  • the wooden profile strips 5 are formed, the corners being rounded accordingly and grooves 6 and recessed grooves 7, for example for the use of a sealing profile or the like, being milled.
  • the wooden profile strip 5 can with on its entire surface a finish or other surface treatment. It is also possible to apply planking, coating or the like 8, which extends over the essential surface of the wooden profile strip 5. This creates an optically perfect surface, which is also applied by the manufacturer of the wooden profile strips 5.
  • the wooden profile strips 5 are cut into correspondingly long sections 9, the connection in the area of the mitres 10 to one another being carried out in a known manner, so that a wooden frame 11 is produced from the wooden profile strip 5, as is the case for windows, Doors or the like is needed.
