Definitions

  • the inventions relate to processes for the production of hollow wooden beams, as well as hollow wooden beam shapes.
  • Round timber outer parts / rinds made of medium-strong and strong round timber diameters, as well as segments / half-timber from the field of small timber serve as starting products.
  • the semi-wood-like raw materials / primary materials are preferably conically profiled on three sides in the wet state and slotted against stress / drying cracks. After drying, the multi-sided finished profiling takes place, and the separation into individual elements, the inversions of which lead to a wooden beam with an external solid wood character and an inner hole (wooden hollow beam), or the separation takes place during or after layer formation.
  • GM 89095758 describes rind uses in which the joining surface profiling processes are to be carried out as soon as the rind is cut off - ie directly when cutting round logs; a method that cannot be exploited (and poor in terms of rejects).
  • Hollow wooden beams - in principle with the character of a Solid wood - with an inner hole arising from the tree curves / tree edge areas, have become known through a study by the CTB, Paris from 1976.
  • the method described only provides for the use of shorter log sections of poorer quality (with parallel joining surface profiling), the 4 individual elements a round is formed into a square bar, the length of which should also be achieved in conjunction with boards.
  • the inventions are based on the tasks of creating processes for the production of hollow wooden beams, and hollow wooden beams of advantageous shapes, in which the best yield - with the least rejection - is achieved, in which the QUALITIES and definable / catalogable shapes (cm3 / cm4 / red. B / cleaned and processed tree edge parts) are in the foreground, in which all standard dimensions (without dependencies on the different types of raw wood) are FLEXIBLE to manufacture; and where - due to the tree ring structures and core-free beam corners - the products offer high load capacities and remain "crack-free" despite considerable fluctuations in wood moisture; So they are also ideal and preferably suitable for external installation (weathering).
  • the object is achieved in that in the so-called sawmill area (FIG. I), the core areas (4) are first removed by parallel cuts (p) on the logs (1) and models (2) coming to the incision, but in this context in principle, no decisions for later uses - that is, no specific requirements for the primary material forms (outer segments) (5) - have to be included, that the usage pattern (31) will only be determined later by the actual primary material forms, and also - depending on the required Quality or tree ring structure - in the case of primary materials, a middle section (26) is rejected by a double cut (26).
  • This sequence makes it possible to create the tree ring structures necessary for corner stability and freedom from cracks in the finished wooden hollow beams (50) (no leakage of both tree rings on only one surface).
  • the sawn-out middle pieces (4) are used in conventional ways (not for hollow wooden beams).
  • the first prerequisite for gauge block profiling (19/10/11 - Fig. VII) is a workpiece that is guided exactly without amplitude. According to the invention, this object is achieved in that - after dressing the lower segment surface (15/19 - Fig. VII) which is distorted during drying - a slitting (20) takes place by means of a circular saw blade, which lies in the plane of the subsequent separation (18), and whereby the workpiece is firmly and tightly guided past the processing stations (FIGS. XIII + XIV) in connection with an attached guide ruler.
  • the glue or joint surfaces in the horizontal position not only have to be available, but also as wide as possible - and the hole as small as possible.
  • the task of optimal structural design or optimized formation type is achieved in that preferably the vertical glue surfaces are reduced by minimal and the surface moments (cm3 / cm4) negligible joint surface gradations (30 - Fig. XI), whereby the enlargement of the hole edge surfaces the processes from swelling / Control shrinkage / diffusion / tension.
  • the advantages of fiber-parallel sawing are inevitably associated with wedge-like middle pieces (Fig. I and III), whose core-free separations lead to half-wood-like, but still wedge-like pieces (5a).
  • the task of using these wedge-like, core-free pieces (5a) for hollow wooden beam production is achieved in that the core-free pieces or parts - with optional plane placements (Fig. XV + XVI) - are separated diagonally into triangular-like elements (39), of which the right-angled legs form the corners of the hollow wooden beam, or the triangles obtained can be separated again into two triangles (K 39) with a right angle each, and the triangles are profiled using the usual methods (41).
  • the triangles made of wedge-like middle pieces are preferably dried out before gluing (low wood moisture Hu), and the wooden hollow beams made from them are preferred only installed indoors.
  • the method is solved in that the workpieces - (as already mentioned in a previous section) - are slotted (20) and guided through a ruler in front of the processing stations (Fig. XIII) and that the adjustment times and adjustment paths of the processing units (35 ) are derived from the feed element (37) pushing the workpiece (36) at the end.
  • the 90 ° ratios of the individual element joining surfaces (10/21) must be created with absolute accuracy, otherwise the individual elements (21) do not require exact dimensional accuracy, since the finished wooden hollow beam is planed again on all sides - including the bevel.
  • raw materials (5) segments (15) of the same shape or the same size are used holistically - to glue 2 segments in series (Fig. XIX) in order to then separate the double halves and to carry out the joint surface processing. and press again in rows.
  • the inventions are based on stabilizing the wooden hollow beam cross sections by introducing suitable materials, preferably at the beam ends in h0.5 (shear stress zones), and in the area of longitudinal beam connections, but also elements for achieving prestressing.
  • the wooden hollow beam (Fig. XXIV) - however formed in cross-section - brings excellent values with regard to deflections (f) because of the almost “standing tree rings” and the fiber-parallel joint surface profiles; through the hole (insignificant for cm3 and cm4) there is a weakening of the cross-section strip in h0.5 - the "b-width" can only be rated with "b-remainder” in the G-module.
  • nailed / screwed / combed / glued / pressed / dowelled / - etc. materials are used to prevent shearing at high shear stresses.
  • Such composite components are introduced in the longitudinal area - also in connection with longitudinal connections.
  • the introduction of the composite materials is preferably preceded by processing of the primary materials (5/15) or individual elements (21), and the composite materials are added during the formation / gluing.
  • the addition of composite materials for longitudinal connections is integrated in the process of cross-sectional surface processing (Fig. XXIV), and the introduction of prestressing elements takes place on or in the finished delivery lengths.
  • Fig. I shows the incision of log sections (1) and models (pre-cut logs 2), or the production of the preliminary material (5) for the hollow wooden beams (50).
  • the left top view with the end views sketched above illustrates the core-parallel removal (p) of the round timber parts required for the hollow wooden beams
  • the second top view from the left with the front view above demonstrates the fiber-parallel (k) separation, the same is illustrated in the middle image, Dar fiber parallel (k)
  • the outer materials can also be cut in connection with the core-parallel (p) incision.
  • the top view with front view shows a preliminary material production that is common in small wood, namely core-parallel (p) separation of the round wood parts when a core board is set; or again (right sketch) fiber-parallel separation (k).
  • Fig. II demonstrates the most varied shapes resulting from the roundwood or model cut of the roundwood parts serving as the preliminary material (5) for the production of hollow wooden beams.
  • Fig. III illustrates in the two left sketches how the wedge-like central pieces (3) resulting from the fiber-parallel (k) round wood incision (Fig. I) can be separated further, and how by cutting out a core board (4) primary materials (5a) are created again with one or three conical surfaces (e, 2 front view sketches on the right).
  • Fig. IV shows cylindrical (1a + 2a) or conical (1b + 2b) profiled log sections, and shows by the dashed lines in the front views that cylindrical and conical logs can be used analogously to the logs Fig. I.
  • Fig. V illustrates the most varied of pre-material shapes that can arise from the cuts.
  • the top right front view shows how wet pre-material (before drying) can be separated in the middle or off-center (16), and how a triangular-like (17) single part results from it; and the sketch below shows how the joining surfaces (10) are conical or parallel (p + k) on the single piece (17) - and the tree edge areas (13 + 14) are processed in between.
  • the middle, right-hand cross-sectional sketch shows how a pre-material (5) separated in the incision area (Fig. I) in the wet state is pre-processed to a segment (15) with a three-surface conical shape (k), while maintaining a certain joining surface width (11) (10) - And is provided with relaxation slots (12).
  • the vertical dashing indicates that the annual ring ends (9) always run out on 2 surfaces during a later cut.
  • the two lower sketches basically show the same (15), they only refer to the tree edge area machining (13 + 14) and a different type of relaxation slits, and the sketches indicate that the pre-processing does not have three faces in every skin. is conical, but only twice or once (p).
  • VI shows the variety of primary material forms in the two rows on the left.
  • cross sections 21 show how the throughput accuracy in the final dimension profiling (19) is fixed by a slot milling cutter (20), the slot width of which is covered by the subsequent separation (18).
  • Fig. VII shows how the pre-processed segments (15) "warp” due to the tree ring structure in the drying process.
  • the middle cross-sectional sketch - and the two outer cross-sectional sketches (quarter pieces) show the gauge block profiling (19) including the tree edge area machining (13/14), the joint surface widths (11), the slot cutter / ruler guide (20), and the separation (18), as well the tree ring exits (9) on 2 surfaces.
  • Fig. VIII demonstrates again the single element production (21) with the processing stages 19/11/20/13/14 with 3-surface conical (k), but with the difference compared to the types described above, that the joining surfaces are not perpendicular to the cross-sectional shape, but oblique (22/23).
  • Fig. IX shows in the left row end views of individual elements (21a) resulting in different sizes due to different Ronholz diameters (24).
  • the bars (50) with a hole (51) sketched to the right always show the same cross-sectional size (24a) by combining individual elements (21a) of different sizes.
  • Fig. X illustrates that - depending on the shapes and combinations of 21a and their joining surfaces (10/11), the weld areas (13) cover the center of the cross-section of the beam, and therefore have to be processed at an angle (14).
  • Fig. XII demonstrates in the forehead and top view the geometric distortions in bent woods, and in what way the axis curvatures (32) via the taper (K) leads to the grid (31).
  • the path-time ratio for the precise, conical adjustments (k) of the stations in the machining center (35) is derived from the feed element (37) inserting the workpiece (36) at the end of the passage (33).
  • XIV demonstrates, analogously to FIG. XIII, the processing in the pass (34) not on workpieces similar to semi-wood, but on quarter pieces (17).
  • XV shows at the top in two end views the wedge-like (3) pre-materials (5a) that result from the parallel splitting of the wood sections, which (left sketch) can be conical on three sides or only conical on one side.
  • the 4 front views below show how the geometries of the primary materials (5a) shift to the diagonal cut separation process (38), and how right angles (40) are formed again on individual elements (39), or how smaller individual elements result from further separations Have (K 39) made with a right angle (40).
  • XVI indicates how the joining surfaces of the individual elements (39 / K 39) are conically profiled (k) and how a bar (65) is to be formed from the triangles (41).
  • Fig. XVII Fig. XVIII illustrates in the front view (42) how 4 individual elements (E 1 7) can be glued by pressing (F1 ...); and the upper sketch (Fig. XVII) indicates that multi-layer pressing of differently sized individual elements with thickness tolerances (x) is not possible.
  • Fig. XIX shows a procedure in which the beam halves (43) are pressed in series in order to then separate the glued 2 Balkan halves (44) (H1 / H2), and after aligning the joining surfaces again by row pressing the beam height (50 / H 1 / 2 ) to form.
  • Fig. XX illustrates a pressing "in the carpet” (46), wherein the 2-layer formation (45) gives the bar width (B). The beam heights (50 / H) are separated from this "carpet" (46).
  • Fig. XXI shows a perspective view of the beams (66) formed from only 2 individual parts (21) with conical (k) or parallel (p) joining surfaces with an open cavity (52), as well as two cross-sectional sketches with the information, as on this beam Corners (E) and interior areas (I) are to be machined.
  • Fig. XXII shows the wooden hollow beam (50) in the top right in 2 perspective views, with references to the hole (51), the hole sizes (53), their edges (57), and the tree rings (55) in the corner area (54 ), as well as tree ring end exits (9) on two surfaces, as well as a cross-sectional diagram to the left of the perspective sketch to clarify the tree ring structures after core area removal (4) and smooth double cut (26) to reach the individual elements (21), and how they are place the tree rings (9).
