Definitions

  • the invention relates to a board stack element, in particular to solid wood construction according to the preamble of claim 1.
  • the individual Slats with the help of nails or with the help of Connected wooden dowels In the case of nailing, the Disadvantage that the board stack element thus formed is not without more on conventional woodworking machines can be edited because the editing tools on the can hit hammered nails.
  • the invention has over the known Board stack elements the task of a board stack element propose this through the use of wooden dowels is easy to machine on woodworking machines and has improved stability.
  • This task is based on a board stacking element type mentioned in the introduction by the characteristic features of claim 1 solved.
  • one according to the invention is distinguished Holzstapelelement characterized in that between the for one Dowels provided holes in two successive Board slats an offset is formed. Through this Offset the holes in two to be joined Board slats intended for the same wooden dowel the dowel is jammed between the boards, causing there is increased strength. Between the wall one of these bores and the dowel results Pressing pressure that sufficient dowel adhesion in Interior of the holes is guaranteed. Such a The created board stack element does not require any more Aid for connecting the board slats to each other.
  • the Offset two holes of the same board lamella that are used for Different dowels are provided in opposite directions Direction. This ensures that when Insert the dowels or when attaching a board the corresponding dowels the respective board the baling pressure cannot give in due to a possible shift.
  • the Boards do not need to be used otherwise, for example Bracing against such at the end faces Compensatory movement are secured.
  • the arrangement of the Dowel holes in connection with the inserted dowels ensures a firm and stable tension.
  • a groove is in turn and a spring between individual boards provided to the to achieve the advantages mentioned in the introduction.
  • the manufacturing process can be accelerated by several, preferably all, holes at the same time in one appropriate board are drilled. It is also through accordingly rigid connections between the in this case individual drilling tools to be provided is also a good one Dimensional accuracy of the individual holes in their relative position to each other.
  • the pre-drilled Board with the help of a swiveling movement of the board holder to Attach in front of the in a fixed dowel holder positioned dowels.
  • a swiveling movement of the board holder to Attach in front of the in a fixed dowel holder positioned dowels hereby, with the help of an axis of rotation, precise guidance of the Board holder and thus the board to be clipped on during of the attachment process.
  • the Board stack built on a different level than that Drilling tools are used to drill the holes.
  • Fig. 1 shows a board stacking element 1, which consists of several stacked board lamellae 2 is formed, the are connected to each other via wooden dowels 3.
  • FIG. 2 shows the arrangement of two adjacent wooden dowels 4, 5 for Connection of an exemplary number of eight each successive board slats 6, 7.
  • Each board slat 6, 7 has two bores 8, 9 and 10, 11 for receiving the Provide wooden dowels 4, 5.
  • the bores 8, 10 each associated with a dowel 4, 5 or 9, 11 successive board lamellae 6, 7 have an offset 12 on. This results in each hole 8, 9, 10, 11 in each board 6, 7 an area 13, 14 in the a pressing or friction achieved by this offset between the hole reveal of the corresponding hole 8, 9, 10, 11 and the dowel 4, 5 arises. This pressing is in the area 13 indicated by small arrows.
  • the principle shown spreads over the total number of board slats 6, 7, away.
  • the offset is arranged so that the holes 10, 11 a board lamella 7 with respect to the corresponding Bores 8, 9 of the previous board lamella 6 in are offset in the opposite direction. This is no front-end clamping elements or the like necessary to shift the individual board slats to prevent each other and the pressing upright receive.
  • the offset 12 is alternating around the Axis of the respective wooden dowel 4, 5 with successive Sequence of board lamellae 6, 7 created.
  • the respective Dowels 4, 5 remain essentially in this right-angled orientation with respect to board lamellas 6, 7.
  • the diameter of the holes 8, 9, 10, 11 before plugging on the dowels 4, 5 can correspond to the dowel diameter, depending on the choice of material, also slightly enlarged or reduced bore diameter can be provided can.
  • the wood of the board lamellas 6, 7 be softer than that of the dowels 4, 5, which are usually made of Hardwood, for example made of beech wood.
  • the reveal of the holes 8, 9, 10, 11 when inserting the dowels 4, 5 in the area 13, 14 of the pressing to the extent that it can be attached to the dowel can.
  • Board slats 2 are fed to a dowel machine 15 (cf. FIG. 3). They are then passed through a plurality of drills 16 provided with the bores described above (see. Fig. 4).
  • a board holder 17 is schematically for Fixing a board lamella 18 before attaching the Holes shown.
  • the board holder 17 is one Rotation axis 19 pivotable, so that the board lamella 18 from its horizontal position by turning the board holder 17 in the end position 17 'arranged in the vertical position 18' becomes.
  • FIG. 6 shows a plan view of a Table 20, above which the various surfaces Dowels 4, 5 in a manner not shown on a Clamping side 21 are clamped.
  • the board lamella 18 (cf. Fig. 5) is in the vertical position 18 'in front of the Mating side 22 of the table 20 (see also Fig. 7). So is the board lamellae 18 'prepared for plugging onto the Dowel 23.
  • the dowel machine 15 is included all the components described above again drawn.
  • the Drill 16 on a vertically displaceable drilling unit 25 are attached, as indicated by the double arrow 26.
  • the drills 16 are also horizontally adjustable to the set the desired offset.
  • the slide 24 extends into the Extend the area of the table 20 and in corresponding Recesses 27 are penetrated by the dowels 23. They are thus able to cover a large area of a board lamella 18 attack and apply even pressure to the dowels 23 to be postponed.
  • the slider 24 are separate or coupled to one another, for example, via a rod To drive hydraulic cylinders.
  • the one after the other arranged slide form in the example above hence a so-called hydraulic cascade slide.
