Definitions

  • the invention relates to a semi-solid wood panel, consisting of at least two layers of glued together wooden profiles, which have two mutually parallel outer surfaces, which are each aligned parallel to the two large surfaces of the plate and each have the same material thickness in each layer.
  • Such solid wood panels are e.g. in a single-layer design for the production of furniture and for the equipment of interiors usual. These plates are usually made with a maximum thickness of 16 to 20 mm. At higher loads or when used in timber structures with higher load capacity requirements, solid wood panels with larger thicknesses and with multiple layers are used.
  • a disadvantage of these plates is their relative to other wood panels and wood materials relatively very high weight, which is particularly disadvantageous for moving components.
  • CONFIRMATION COPY DE 661 763 describes a plate, which consists of juxtaposed hollow profiles, which are each constructed of four wooden strips which enclose a rectangular cavity.
  • the disadvantage of this wood panel is the relatively high cost and the required in the production, relatively high accuracy: For the connection of the four
  • Wood strips a tongue and groove joint is proposed, however, which requires a complex milling of the grooves and the springs while cutting a portion of the wood, which should have been saved by the cavity actually.
  • the wooden strips have only a rectangular profile and only glued to the other wooden strips, the strips are no longer performed during assembly by the groove, but require a clamping device, which increases the cost.
  • the invention has set itself the task of creating a cost-effective solid wood panel, which can be easily manufactured, has a relatively low weight and still provides almost the same stability as the known solid wood panels, but compared to less raw wood and less Glue needed.
  • the invention teaches that the wood profiles have an approximately trapezoidal cross section and together with at least two adjacent, further wood profiles each form a cavity extending in the longitudinal direction of the wood profiles and which is closed in cross section.
  • the wood profiles have a trapezoidal cross section, so have four edges. In addition to the two end faces, the wood profile thus has four elongated surfaces. Around To designate areas with different terms, Trapezen uses the usual name for the edges.
  • a trapezoid is a flat square with at least two parallel sides of different lengths.
  • the longer side is called the “base” of the trapezoid, the shorter side than the “base side”.
  • the two sides which are not parallel to each other and which connect the base side and the base of the trapezoid are called "legs".
  • the wood profiles of the first layer are glued or otherwise connected to the base surfaces of the wood profiles of the second layer adjoining the first layer, in each case with their second, narrower outer surface - the base surface.
  • the wooden profiles of the two adjacent layers are thus each rotated by 180 ° about its longitudinal axis against each other or in other words: the wood profiles of the upper layer are compared to those from the lower layer "upside down.
  • the longitudinal directions of the wood profiles of the two layers are not parallel. In practice, they will usually cross at right angles, but it is also conceivable every other angle.
  • each cavity has a triangular profile. On all edges of a sol- Therefore, a series of triangular openings can be seen in two-layer semi-solid wood panels.
  • the invention preferably variants of the wood profiles, which have only flat surfaces. Since the wood profiles according to the invention do not have surfaces whose continuations protrude into other surfaces, these surfaces can be manufactured with tools which project beyond the edge of the surfaces, e.g. rotating saw blades. Thanks to their narrow sawing seam, they produce a significantly lower loss of wood compared to milling tools.
  • these four surfaces can be made in a single pass with a machine having four saw blades aligned with the surfaces.
  • the invention proposes, as an embodiment, that in the trapezoidal cross-section, the edge between the first, wider outer surface - the Base surface - and the adjacent first leg surface is flattened to a chamfer which is parallel to the opposite, second leg surface.
  • this fifth longitudinal surface requires a further machining operation or an additional tool in a continuous machine. This, however, ensures that the edge of the trapezoid substantially larger surface of the chamfer can be glued to the adjacent leg surface.
  • wood glues on the current state of the art, it is possible that the bonding of the chamfer with the adjacent leg surface is at least as or more resilient than the connection between two adjacent wood fibers within a wooden profile.
  • the narrow chamfer and the opposite second leg surface of each wood profile are aligned perpendicular to the outer surfaces. This results in interesting combination options.
  • Glued or otherwise connected wood profiles As a result, relatively numerous and very small, triangular cavities are created in one layer between the adjoining wooden profiles. The area of each individual cavity can be doubled in the case of a two-layer semi-solid wood panel by gluing a second such layer mirror-symmetrically to the first one. Then the cavities are also triangular, but twice as large. At two opposite end edges of such a plate is then in each case a series of small, triangular openings to see.
  • a solid wood panel which has a series of triangular openings on all four edges.
  • the bevel of each wood profile is glued or otherwise connected in another arrangement with the chamfer of an adjacent wood profile and the vertical leg surface of each wood profile with the vertical leg surface of the adjacent Wooden profiles connected.
  • each layer of wood profiles so two chamfers and then two vertical leg surfaces and then two vertical chamfers are connected to each other. If such a layer is adhered to a second layer in reverse, that is to say in mirror symmetry, diamond-shaped cavities are formed.
  • the width of the wood profiles is probably mostly in the range of a few centimeters, pivoting angles of the layers against each other of less than 10 0 make less sense.
  • the layers of the wood profiles are combined so that at least one of the two large areas of the solid wood panel is not a plane, but is crossed by mutually parallel, V-shaped grooves. This changes the sound reflection and creates an additional parameter for the optical design. It is also possible that grooved strips alternate with smooth, flat strips or areas. However, in practice, flat surfaces are likely to be preferred.
  • the solid wood panels according to the invention are suitable for the production of furniture, table tops, cladding and wall and roof structures. Through the cavity, the heat transfer resistance increases compared to a conventional solid wood panel by 25 to 30%. This is particularly important in the construction of wooden houses or wall elements for exterior walls.
  • insulating materials e.g. foamed plastic or even vacuum insulation elements are inserted or incorporated.
  • the currently known woodworking machines and the usual presses can be used.
  • the variant with a chamfer and a second leg surface, which are aligned perpendicular to the base surface and the base are particularly interesting when cuboid squared timber is to be used. Since in this variant, only the first leg surface is not perpendicular to the other surfaces, it is proposed to divide a cuboid wooden strip into two identical wooden profiles by means of a single cut, which is oriented "obliquely" to the remaining edges of the cross section
  • the advantage is that, apart from the sawing seam itself, no further waste is produced.
  • a - albeit very small - amount of wood waste is produced in the following work, in which some material is removed from the edge of the "beveled" cut surface of the previous operation to form the chamfer, which runs parallel to the already existing second leg surface
  • a subsequent advantage of the invention is that the wood profiles can be inserted into the press "on strike” and no further auxiliary devices are required ,

  • each individual wooden profile 3 is connected to each other, each having two mutually parallel outer surfaces, which are each aligned parallel to the two large surfaces of the plate.
  • the material thickness of each individual wooden profile 3 is the same, so that the outer surfaces of these wooden profiles 3 are supplemented in each case to a large area of the solid wood panel according to the known state of the art.
  • FIG. 2 shows a semi-solid wood panel according to the invention.
  • the wood profiles 3 used here have only half the material thickness of the wood profiles 3 according to the technique in FIG.
  • Embodiment variant in Figure 2 two layers S1.S2 with each other connected.
  • Each layer S consists of juxtaposed wood profiles 3, which in this embodiment have an approximately trapezoidal cross-section, which can be seen on the right as a single part wood section 3 that the profile is not exactly exactly trapezoidal, but at its left lower end by the bevel 35 is reduced in size, so that it is strictly speaking not a quadrangle but a pentagon.
  • the first leg surfaces 33 which run "obliquely" to the remaining surfaces of the wood profile 3, form the inner wall of the here diamond-shaped cavity 4 after the gluing of the wood profiles 3.
  • each wood profile 3 is connected via a respective first joint 1 with a chamfer 35 of an adjacent timber section 3.
  • first joint 1 is so narrow, as is common for solid wood panels on the current state of the art. Therefore, only a relatively small amount of adhesive in the joint 1 is required to connect two adjacent chamfers 35 of adjacent wood profiles 3 together.
  • the respective second leg surfaces 34 of each wooden profile 3 are glued via a second joint 2 with an adjoining second leg surface 34 of the adjacent wooden profile 3.
  • the second joint 2 is just as narrow as the first joint 1.
  • FIG. 2 clearly shows that two wood profiles 3, which are connected to one another at their second leg surfaces 34, together again form a symmetrical wood profile which, apart from the two bevels 35, is approximately trapezoidal. From Figure 2 is thus another, possible embodiment for the wood profiles
  • FIG. 3 shows a six-layer semi-solid wood panel according to the invention. It is composed of three of the double layers shown in FIG. In this case, the middle two layers have been pivoted by 90 ° with respect to the other two layers.
