Definitions

  • the invention relates to a method for producing a wooden beam according to the preamble of claim 1.
  • the individual elements are each produced with a similar cross-section, with a relatively large amount of waste occurring in the round wood sections serving as the starting material. If, in the prior art, the individual elements made from round timber sections have a non-constant cross-section, the cross-section of the finished wooden beam also tapers, so that, in order to obtain parallel shapes, it must subsequently be divided into individual pieces and processed.
  • the invention has for its object to provide a method for producing a wooden beam according to the preamble of claim 1, in which the waste or material loss can be minimized to produce a wooden beam with a constant cross-section.
  • the wooden beam produced with the method according to the invention is distinguished by a number of considerable advantages.
  • the individual element is shaped like a truncated pyramid, it is possible to use the naturally existing conicity of a log section without a reduction to a constant cross-sectional area of the starting material being necessary before its further processing.
  • the amount of residual material obtained during processing can thus be considerably reduced, since the individual elements can be put together to form a wooden beam, the cross section of which, by suitable turning or appropriate assignment to one another Length is constant, and which corresponds approximately to the average diameter of the log section used.
  • the truncated pyramid-like parts represent the areas of the individual elements which are in contact with one another, intimate contact of the individual individual elements is ensured, as a result of which a high degree of strength can be achieved.
  • the side of the individual element facing the cavity is preferably frustoconical, while the edge regions of the individual element which adjoin an adjacent individual element are truncated pyramid-like.
  • the individual elements are each given an inclined angle with respect to the truncated pyramid-like areas.
  • the individual element is provided with at least one slit on the side facing the cavity, this favors the course of tension in the event of fluctuations in wood moisture.
  • the individual pieces can also have outer surfaces of different widths, for example to arrange the central cavity off-center, so that further machining operations, for example notches, recesses or the like, can be provided on one of the sides of the wooden beam.
  • the edge regions of the individual element with which it is in contact with an adjacent individual element are structured.
  • the structuring can be carried out in the form of a tongue and groove configuration, or in a similar manner, in order to ensure a stronger connection between the individual individual elements.
  • add-on parts can be provided on the wooden beam, for example additional boards, facings or the like, and it is also provided that a high support is formed by several wooden beams connected to one another.
  • the method according to the invention is simple in relation to the usual methods for cutting open a log section, few work steps are required and there is particularly little waste or residual material.
  • the log section can be subdivided into individual elements by sawing, knives or milling.
  • a first processing step two individual elements are initially aligned with one another and machined in the form of a truncated pyramid at their edge regions - and that the individual elements are then connected in pairs, and that in a second processing step the two pairs of individual elements on their edges are truncated pyramid-shaped and connected to the wooden beams.
  • This procedure essentially allows to divide round, conical base material into the four individual elements by separating cuts, without having to carry out any work on the circumference of the base material.
  • FIG. 7 shows an end view and a side view of the finished wooden beam 14, from which both the essentially central cavity 5 can be seen and the one that is mutually turned Assignment of the individual elements 1-4.
  • the individual elements 1-4 are each connected to one another in the area of the edge regions 8, for example by gluing, nailing or the like.
  • a measurement of the output beam 15 is advantageous. It is possible, starting from the mean diameter of the starting section 15, to determine the maximum possible cross section of the finished wooden beam 14 and to determine the corresponding bevels of the frustum-like edge region 8.
  • FIGS. 2 and 3 each show end views of an output section 15 already divided into individual elements 1-4, in which one or more core planks or middle pieces 13 have been cut out. These can be used separately.
  • Fig. 4 the assignment of two individual elements 1 and 2 is shown in the front view, which are each provided with longitudinal slots 9, which prevent wood tension, and thus a distortion of the individual elements.
  • Fig. 5 shows cross-sectional views of wooden beams, e.g. similar to log building. It is possible to profile the wooden beam, for example to create corresponding optical effects, or to seal one another.
  • FIG. 6 An embodiment is shown in FIG. 6, in which the front ends of the wooden beams 14 are each closed by means of an aperture 10 in order to seal the cavity 5 both optically and technically.
  • the aperture 10 can be put on or inserted.
  • FIG. 7 shows that the individual elements 1-4 have different side lengths can have, so that the cavity 5 is arranged off-center by a certain amount. In this way, recesses 17 or notches 16 can be worked out.
  • the respective edge areas 8 of the individual elements 1-4 have different widths 18, 19.
  • FIG. 9 shows the possibility of connecting additional attachments, for example boards or beams, to the wooden beam 14 according to the invention in order to increase its strength and / or cross section.
  • Fig. 10 shows a composite of four half-wood-like individual pieces (21) with additional attachments.
