Definitions

  • the invention relates to a wooden beam and method for its manufacture.
  • a disadvantage of corresponding conventional beams is however, in the fact that, due to the complex process compared to solid wood is more expensive. In addition, there is an enormous loss of material from logs to finished beams, whereby the cubic meter price of the bar increases again and finally is several times the solid wood beam.
  • the object of the invention is a to provide higher quality beams, the described, known from the prior art Does not have disadvantages.
  • Figure 1 shows schematically the conventional incision method for the generation of rectangular slats.
  • Figure 2 shows schematically the star incision method to produce the star or triangular lamellae, which are used to manufacture of the bar according to the invention can be used.
  • Figure 3 shows schematically a conventional one Rectangular slats built beams.
  • Figure 4 shows schematically the invention Star or triangular lamellar beams.
  • Figure 5 shows schematically the manufacturing process of the bar according to the invention.
  • the one used to make the triangular slats Incision method differs from that conventional ( Figure 1) in that there are no rectangular Cross sections generated, but after z. B. with help a profile cutter, for example, and preferably one Milled octagon from the round trunk with a so-called Star cut into triangular lamella 1 ( Figure 2). In this way, sixteen triangular blades 1 generated with a rectangular cross section, the long sides 2/3 are radial ( Figures 2 and 4).
  • the second advantage of this procedure is the essential one higher yield of sawn timber. So with the conventional Incision ( Figure 1) the yield of the main product in the range of 45 - 50%, plus 10 - 15% side goods. In contrast, the star incision ( Figure 2) yields up to 73%; in addition, the lumber is here completely Main product available. The average yield is thus around 25% higher in the star incision process than with conventional incisions.
  • Star slats can cost from 600, - to 650, - DM for 400, - to 450, - DM, about 2/3 of the previous one Costs.
