    The invention relates to a method for the production of several wood layers having plates. Such panels of wood are advantageously for the production of rigid wooden structures, furniture, walls, coated panels, doors, etc. replaceable. Such panels are currently produced by gluing several layers of wood.
    The aim of the invention is to produce such plates cost with little effort and high strength.
    According to the invention, the production of such plates is such that at least one, an odd number of layers owning, at least three-ply, preferably present in the form of a residue or waste piece, wood multilayer board or cross-laminated board in which the individual interconnected layers with adjacent, are formed in the same direction aligned and interconnected strips and the strips of each layer have a longitudinal direction of the respective bar fiber direction and the strips are arranged in superimposed adjacent layers each with mutually perpendicular grain directions, parallel to the fiber direction or at an angle of up to 10 °, preferably up to 5 °, to the fiber direction (F) of the strips located in a predetermined layer, preferably an outer layer, by parallel separating cuts in several layers of wood aufwei sende plates is shared and thus advantageously plates are created, which have the same structure with respect to their wood layers.
    The wood multilayer boards or cross-laminated wood panels used to create the panels are made by extending the layers forming a layer parallel to each other and behind one another with a longitudinally extending fiber direction so that a predetermined area is filled with these strips arranged in parallel and having the same fiber direction. On this layer strips are placed, which are perpendicular to the already laid strips until this is also designed and filled with such strips further layer. It is on another layer with strips created such that the strips in this layer have a fiber direction that is perpendicular to the fiber direction of the strips in the previous layer. Such sandwich-like layering of each having alternately perpendicular to each other having fiber directions bars is known in the production of Kreuzlagenhoiz or cross-laminated board and also in specially constructed wood multilayer boards.
    The strips used may be boards, strips, rods or the like molded profiled woods of any kind of wood. The cross-sectional area of the individual strips of at least one layer is usually chosen to be the same and varies between square and more or less elongated rectangular.
    The strips in the individual layers and the individual layers are connected with each other. If, in the following, a connection is mentioned, this means a gluing or gluing, wherein the gluing or gluing is advantageously carried out under the action of a corresponding pressing pressure, which is maintained for a certain period of time.
    The individual layers formed with the strips are connected to one another, thereby creating a multilayer wood panel in which the fiber directions of the strips in adjacent layers each extend perpendicular to one another.
    According to the invention, such a wood multilayer board is now divided by parallel separating cuts. The division with cuts of rectangular Hoiz multilayer slabs is parallel to a longitudinal or transverse edge or at an angle of up to 10 °, preferably up to 5 ° inclined, the respective edges usually parallel or perpendicular to the fiber direction of the respective layers located strips. The separating cuts can be guided in such a way that strips are cut once or several times in the longitudinal direction. However, it is also possible to perform the division in such a way that in the separating cuts the distance of the guided cuts is greater than the width of a bar.
    According to the invention obtained plates with wood layers, which have an odd number of adjacent and interconnected, elongated layers of wood, - wherein at least one of these layers of wood is formed by at least one wooden strip whose fiber direction in the longitudinal direction of this bar or at an angle of up to 10 °, preferably up to 5 °, extending to the longitudinal direction, - wherein at least one other of these layers of wood is formed by a number of parallel to the alignment of the wooden strip in the plate successively arranged interconnected pieces of wood, wherein the fiber direction of these pieces of wood perpendicular to the fiber direction of at least one strip of wood runs and - wherein juxtaposed wood layers perpendicular to each other, but have non-intersecting oriented fiber directions of the wood strips and pieces of wood.
    The panels made in this way are advantageously used to create wood composite panels with them. The procedure is such that a predetermined number of plates obtained in the cutting of Hoiz multilayer boards or board plywood boards with their surface in the
    Wood multilayer plate or cross-laminated board forming surfaces adjacent to each other is connected to a wood composite panel.
    The wood composite panels constructed with such panels have high rigidity and good strength behavior and can be used for building purposes and for the production of flat objects, for example wall surfaces of wooden houses, for furniture construction, for doors and other wooden constructions. It is particularly advantageous that waste and remaining pieces of cross-laminated board or laminated wood panels can be recycled in this way.
    A homogeneous plate structure is achieved when an equal succession and an equal number of wood sheets facing plates, which were preferably obtained when cutting one and the same wood multilayer board or cross laminated board, are connected side by side to a Hofzverbundplatte or core plate. However, this arrangement is not mandatory. It can also be interconnected plates that come from differently constructed cross-laminated board or multi-layer wood panels and thus have different numbers of wood layers and a different sequence of wood layers.
    For reasons of strength can be provided that adjacent plates are connected so that the abutting surfaces of the pieces of wood in the layers formed by the individual pieces of wood offset from each other, in particular centrally offset aligned.
    An advantageously high strength owning arrangement or construction with the plates according to the invention is obtained when a predetermined number of panels obtained in the cutting of wood multilayer boards or board plywood panels with their surfaces in the wood multilayer board or cross-laminated board forming surfaces adjacent to each other is connected to a wood composite panel and / or when a predetermined number of wood composite panels are sandwiched together, the wood panels provided in adjacent panels having a fiber direction extending in the longitudinal direction of the wood panels being aligned with the grain direction perpendicular to each other and / or on at least one of the opposite surfaces of the obtained one Wood composite panel or by sandwiched panels cover plates or veneers or cladding panels are connected.
    A multiple wood layers having plate according to the invention characterized with the features of claim 11. A Hoizverbundplatte made of plates is inventively characterized in that the wood composite plate has a number of adjacent, interconnected plates of equal thickness. For the application and further processing of boards according to the invention, it may be advantageous if external wood layers are each formed by at least one strip of wood whose fiber direction is parallel to the side surface of the plate and / or that external wood layers with two identical layers or against internal layers of wood are formed double-ply, wherein such external wood layers are each formed with two juxtaposed, same fiber direction owning wood strips or pieces of wood.
    The width of a wood layer may correspond to the width of a wooden strip or it may form a Holziage several superimposed or juxtaposed with respect to their fiber direction the same oriented wood strips.
    A durable, solid structure results when the wood pieces in a succession arranged Hoizstücke are connected to each other and / or the pieces of wood and / or the wooden slats and / or the wood layers are glued or glued together optionally using pressure.
    To achieve uniform strength, it is expedient if the adjacent plates have the same sequence and / or an equal number of layers of wood and / or the adjacent plates 10, 10 10 " of one and the same multilayer wood board or plywood board 1. 1 ', 1 " come. It is quite possible that not enough strips can be produced from a remainder of a KLH plate to make a template. In this case, it is convenient to find a KLH plate of identical construction to complete the template.
    In a further development of a wood composite panel according to the invention can be provided that the wood composite panel or Kemplatte is connected on its upper and / or lower surface with a cover plate or a cross-laminated board or veneer board or another wood composite panel or core plate, wherein when connected to another wood composite panel with the wood strips extending in their longitudinal direction extending fiber direction in adjacent Hoizverbundplatten extending in mutually perpendicular directions.
    In the following the invention will be explained in more detail with reference to the drawing, for example.
    1 to 3 and 4 to 6 each show in plan view us side views a cross-laminated board or at the same time front views of the panels obtained by separating cuts, Fig. 7 to 14 show wood composite panels in plan view and frontal view, which were each created with the plates according to the invention.
    Figs. 1 and 3 show sections through a multilayer wood board or cross-laminated board 1, 1 Γ, as shown in Fig. 2 in Draufeicht. The
    Wood multilayer panel 1 comprises three superimposed layers 2, 3 constructed from strips 4. The multilayer wood panel 1 * comprises five layers 2, 3 and the wood multilayer panel 1 " comprises seven layers 2, 3. It can be seen that the layers are arranged such that the fiber direction F of the strips 4 forming the layers in the individual layers 2. 3 runs perpendicular to one another. Thus, in the multilayer wood panel 1, the middle layer 3 has a fiber direction which is perpendicular to the drawing surface, while the strips 4 lying in the outer layers 2 have a fiber direction F extending in the image plane. The strips 4 of a layer 2, 3 may have the same or different cross section. It is essential that a continuously filled contiguous layer 2, 3 is formed.
    In Fig. 2 is a plan view of a multilayer wood panel 1, 1 ', 1 " illustrated, wherein the extending in the cover layer 2 bars 4 are shown.
    As can be seen from FIG. 2, separating cuts TS, preferably at equal intervals, are guided parallel to the strips 4 or perpendicular to the strips 4 and with each cut a plate can be created whose structure is defined by the layer sequence of the wood multilayer plate 1, T, 1 " is predetermined and corresponds to the cross section, as shown either in Fig. 1 or in Fig. 3. Depending on the number of layers 2, 3, a plate 10 is obtained which has three, five or seven wood layers 11, 12, as shown in FIGS. 2 and 3. The angle of the separating cuts can deviate up to 10%, preferably up to 5%, from the longitudinal extent of the respective strip 4 or its fiber direction, without substantially influencing the strength properties of the sheets obtained.
    The plates 10 shown in Fig. 3 above are obtained at separating sections TS transverse to the upper edge of the wood multilayer plate 1 shown in FIG. 2 and show in its two outer layers perpendicular to the grain of the strips 4 cut wood pieces 5. In its middle layer 11, the plate 10 comprises a continuously extending bar 6, the Fasemchtung F perpendicular to the grain direction of the formed with the pieces of wood 5 position.
    Depending on the number of layers 2, 3 of the Brettsperrhotzplatte 1,1 ', 1 " you get plates 10,10 ', 10 " with three, five or seven layers. The plates 10, 10 ', 10 " shown in FIG. reproduce the cross section of the plywood boards 1, T, Γ.
    The plates 10, 10 ', 10 " shown in FIG. obtained with separating cuts, as they are indicated or executed in the lower part of the cross-laminated board shown in Fig. 2. If one separates the cross-laminated board with separating cuts TS, as shown in Fig. 2 at the left upper edge of the cross-laminated board, we obtain plates 10, 10 *, 10 ", in which the continuous strips 6 form the outer layers and with Hotzstücken Alternate 5 composite layers.
    In Fig. 4 a cross-laminated board 1 is shown, in which relative to the cross-laminated board 1 shown in Fig. 2 for the outer layers relatively wide strips 4 are used, which are parallel to the shorter side of the cross-laminated board 1. Even with such trained cross-laminated timber panels 1 separating cuts TS can be made parallel to the short side or to the long side. Depending on the guidance of the separating cuts are obtained plates 10, 10 ', 10 ", which are alternately formed wood layers 11, 12 with continuous or arranged with their longitudinal direction parallel to the fiber direction bars or pieces of wood 5. The structure of the obtained plates 10, 10 ', 10 ", 10 " corresponds to the cross sections shown in Fig. 5 and 6 of the cross-laminated board 1, depending on the location of the cuts TS.
    The plates 10 '" are plates, created with a cross-laminated board, the double-trained and with respect to the separation joints of the strips 4 has not staggered outer layers. A corresponding appearance or a corresponding succession of the layers or wood layers after carrying out the corresponding separating cuts is shown in FIGS. 5 and 6.
    According to the invention it is provided that the resulting plates 10, 10 ', 10 ", which are readily replaceable in their own right for construction and construction purposes, are joined together to form wood composite panels. For this purpose, as shown in Fig. 7, a number of, preferably thick, plates 10 and 10 'and / or 10 " placed next to each other and connected. This results in composite panels 7, 7 ', 7 ", 7"'. If plates 10 'are juxtaposed and connected, as shown in FIG. 6, a hollow composite plate 7', as shown in FIG. 8, is obtained. Fig. 9 shows a wood composite panel 7 " with panels 10 " with five layers of wood 11, 12 was created, with three such plates were juxtaposed and joined.
    In general, the plates are joined to the surfaces which have formed the surface of the wood-clad sheets subjected to the cuts. The number of interconnected plates is freely selectable.
    Fig. 10 shows the connection of panels 10 '"in which - as shown in Fig. 6 - the outer layers were formed double or with two last layers.
    From Fig. 11 it is apparent that wood composite panels or core plates can be formed, which have a proportion of layers formed with pieces of wood 5 12, which is higher than the proportion of layers formed with strips 11 1. It may be advantageous when the individual layers of wood 12 formed with pieces of wood 5 are arranged next to each other by plates 10, 10 ', 10 " with respect to their impact or their separation surfaces 15 are arranged offset from each other. Advantageously, the separating surfaces are each offset centrally. Composite wood panels with staggered plates are also shown in Figs. 12, 13 and 14 for panels having a different number of wood plies 11, 12. As shown in FIG. 14, the inserted plates 10 " ' a double outer surface.
    In principle, it is also possible to use plates 10, 10 ', 10 " with different structure of the wood layers 5, 6 to form a wood composite board. A regular sequence of wood layers is preferred.
    The wood layers of a plate preferably have the same thickness, but may have different dimensions of their heights according to the existing layer thicknesses of the separated cross-laminated board panels.
