Definitions

  • the invention relates to a method for producing support bars, profiles, beams or the like. From pressed small vegetable parts according to the features listed in the preamble of the main claim.
  • DE-OS 32 27 074 proposes a method for producing support bars, profiles, beams and the like, according to which the small parts mixed with binder, in particular wood chips, are filled into a cavity formed by four press rams. These rams are pressed against each other in a certain order to compress the batch, the frequency of the pressing processes being at the discretion of the person skilled in the art, depending on which product is to be produced. Post-compaction in the vertical direction appears decisive, while maintaining the pressing pressure acting on the side surfaces, only then to carry out the curing of the compact while maintaining the pressing pressure.
  • profiles for example in I-cross section, can be made from small wooden parts, the bending strength of which is at least equal to that of profiles of the same size from grown wood.
  • the object of the invention is to develop measures) which are intended to further increase the bending strength or load-bearing capacity of such profiles, irrespective of the cross section.
  • the object of the invention is achieved with the characterizing features of the main claim.
  • the basic idea of the invention is that the pressing pressure of those pressing dies which act in the main loading direction of the object to be produced is not allowed to act directly on the body to be pressed, but via board-shaped strips which, after suitable pretreatment with adhesive or similarly acting materials, are used Have the property to transmit the baling pressure on the one hand and on the other hand to be firmly connected to the mixture of small parts of vegetable type to be pressed.
  • the invention does not exclude that the board-shaped strips used according to the main claim can also be connected to the outer surfaces of the profile web according to the feature of FIG the bending stiffness.
  • the invention also goes so far as to provide the other or vice versa or both together instead of one planking.
  • the invention provides, in accordance with the feature of claim 4, to use two-layer or multilayer board-shaped strips for planking. These can be lamellae or strips that differ in terms of their wall thickness, which can also consist of different materials.
  • the invention also relates to the product that can be produced by the method, which differs from the direct product to be expected from the method in that the connecting surface between the pressed profile body consisting of small parts and the board-shaped strips is uneven, this unevenness towards Profile body can be arched protruding.
  • This uneven connecting surface has the advantage that the board-shaped strips form a positive connection with the pressed profile body made of wooden parts, not only via the introduced binder, but also via the convex connecting surface, in relation to the pressed profile body.
  • the board-shaped strips thus not only increase the load-bearing or bending strength of the manufactured profile, but also the torsional rigidity.
  • the deformation tool is formed by the press rams 10, 11, 12, 13, which are movable along the guides 14 and enclose the cavity 9 between them.
  • Fig. 2 shows that the filling material 21 is poured into the cavity 9, which preferably consists of small wooden parts mixed with binders.
  • the cavity 9 which preferably consists of small wooden parts mixed with binders.
  • other small plant parts e.g. crocheted straw and the like to use. This dosage and the gluing of these small parts is to be considered as state of the art and therefore requires no explanation.
  • the individual board-shaped strips 19, 20 can consist of two or more layers 25, 26 which have previously been glued together. With such layers 25, 26 there will of course be a slight curvature of the connecting surface 23.
  • FIG. 9 it is shown that, in addition to the press-shaped strips 19, 20, board-shaped strips 22 covering the side surface of the web 3 can also be used, which consequently are firmly connected by the side press punches 12, 13 during the pressing process according to FIG the small parts forming the web 3 are brought.
  • the Randbe rich the lateral press rams 12, 13 also so that the board-shaped strips 22 are, so to speak, embedded in the web 3 and from there the transition to the belt 2 takes place continuously.
