Definitions

  • the invention relates to a method for producing a wooden beam, as well as a wooden beam in composite construction.
  • the wooden beam consists of several interconnected individual elements that extend in the longitudinal direction of the wooden beam and enclose a cavity, the wooden beam having essentially mutually parallel, opposite side surfaces.
  • Wooden beams are also known, in which individual elements with a rectangular cross section are used.
  • the individual elements are each produced with a similar cross section, with a relatively large amount of waste the logs serving as the starting material occurs. If, in the prior art, the individual elements made from round wood 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 wooden beam and a method for its production, in which the waste or material loss can be minimized to produce a wooden beam with a constant cross-section.
  • the invention is achieved in that the individual element is at least partially frustoconical on a side facing the cavity.
  • the wooden beam according to the invention is characterized by a number of considerable advantages. Since 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 prior to its further processing. The amount of residual material arising during processing can thus be considerably reduced, since the individual elements can be put together to form a wooden beam by suitable turning or corresponding assignment, the cross-section of which is constant over its length and which corresponds approximately to the average diameter of the round timber section used . Because the truncated pyramid Like parts that represent the area of the individual elements, which are in contact with each other, an intimate contact of the individual individual elements is guaranteed, whereby 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 stress curve 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 processing, 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 firmer 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 intended to form a high beam by several interconnected wooden beams.
  • the invention is achieved in that a conical round timber section is quartered substantially in the longitudinal direction to produce the individual elements, the individual elements each having two surfaces that are perpendicular to one another, that the individual elements are shaped like a truncated pyramid on the edge regions of the original outside - and that the individual elements alternately turned - and connected to a wooden beam with the same cross-section over the length.
  • the method according to the invention is simple in relation to the customary 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 in a second processing step the two pairs of individual elements on their edge rich truncated pyramid shaped and connected to the wooden beam.
  • This procedure allows essentially round, conical starting material to be divided into the four individual elements by separating cuts, without having to carry out any work on the circumference of the starting material.
  • starting materials are used that have a relatively large diameter, which is larger than the desired cross section of the finished wooden beam, or if the corners of the finished wooden beam should not consist of the core area of the round timber section, then at least one core plank or a middle piece is cut out and used separately.
  • FIG. I shows in the upper area an end view and a side view of a conical log section which has different diameters on the stick area and on the braid area.
  • the lower part of FIG. I shows a side view and an end view of the starting material after the edge regions 8 of the individual elements 1-4 formed by longitudinal cuts made at right angles to one another have been processed.
  • FIG. II shows an end view and a side view of the fully divided wooden beam 14 according to the invention, from which both the essentially central cavity 5 can be seen and the mutually reversed assignment of the individual elements 1-4.
  • the individual elements 1-4 are each connected to one another in the region of the edge regions 8, for example by gluing, nailing or the like.
  • IV and V each show end views of an output section 15 which has already been divided into individual elements 1-4 and in which one or more core planks or middle pieces 13 have been cut out. These can be used separately.
  • Fig. VI 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.
  • VII shows cross-sectional views of wooden beams, e.g. similar to log building. It is possible to profile the wooden beam, for example in order to produce corresponding optical effects, or to seal one another.
  • Fig. VIII an embodiment is shown, in which the front ends of the wooden beams 14 are each closed by means of a panel 10 in order to seal the cavity 5 both optically and from a technical point of view.
  • the aperture 10 can be put on or inserted.
  • Fig. IX of the wooden beam according to the invention shows that the individual elements 1-4 may have different side lengths, 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 regions 8 of the individual elements 1-4 have different widths 18, 19.
  • X shows the possible variations of the method according to the invention.
  • Fig. XI different possibilities are shown to profile the individual elements 1-4 at their edge areas 8, for example by gradations, tongue and groove configurations, by inserting a separate groove or the like, in order to create a connection between the individual elements 1-4 to improve.
  • XIa 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. XIb shows a composite of four half-wood-like individual pieces (21) with additional attachments.
  • the invention is not limited to the exemplary embodiments shown; rather, there are various modification and modification possibilities for the person skilled in the art based on the basic principle, the outer areas of the log section forming the coreless interior area of the composite beam according to the invention, while the yield of the conical log path is used.
