Wooden building element with wooden layers

The invention relates to a wooden component with wooden layers according to the preamble of claim 1. Such a wooden component can be used for walls, ceilings or roofing and the like of buildings, vehicles etc. This wooden component has at least two layers of wood.

Such a wooden component is already known from G 92 07 654.8. The wooden component has at least five layers and has layers arranged in a rust-like manner, running crosswise and in parallel planes. This training ensures good stability and a certain freedom from shrinkage, which also makes it possible to use excess wood from wood edge products. A middle layer consists of strips, boards or the like which are laterally spaced apart. These distances result in cavities which, on the one hand, lead to a weight saving, but on the other hand, represent cold or heat bridges. Another disadvantage is the poor sound insulation values that are achieved with this wooden construction element. It is also disadvantageous that cracks form very easily when the boards or strips dry, so that the boards or strips become rejects and can no longer be used for the wooden construction element.

From DE-C-835 646 a wooden board is known as a component of layers consisting of layers, which has several wooden layers, which are provided on at least one side with a structure, the structure being a grooving that extends in the longitudinal direction of the wooden layers or Boards that make up the layers of wood are formed. The wooden construction elements described here are, however, only relatively difficult and cumbersome to manufacture, since it is not possible to produce corresponding wooden construction elements endlessly to manufacture. Endless production is forbidden here because the existing and used boards with predetermined dimensions each lead to a certain dimensioning of the known wooden building elements, so that a certain wooden building element with a certain length is always obtained at a distance from certain standard board dimensions.

Other wooden components or prefabricated components made of wood are from G 93 02 447.9 Ul, DE-GM 1 838 415, DE-GM 75 32 453, DE-GB 1 920 170, DE 25 33 149 AI, DE 92 09 042.7 Ul, the DE 38 14 589 AI and US-A-4,086,382 known.

The invention has for its object to remedy disadvantages of the prior art; in particular, a wooden structural element with high thermal and acoustic insulation values should be made available in the simplest possible way while reducing the rejects, which can be mass-produced particularly easily, in particular can be produced endlessly.

The object on which the invention is based is achieved by a wooden construction element having the features listed in protection claim 1.

The advantages to be achieved according to the invention are based on the fact that the wooden structural element according to the invention can be produced endlessly if the at least two or more wooden layers are arranged diagonally to one another, the structure or the grooving preferably being essentially parallel to the longitudinal edges of the wooden layers or the board that forms them. However, the structure can also run diagonally or in a different way diagonally, parallel or crosswise. Individual slots can also be provided in a row or offset from one another, crosswise or in another direction. Zigzag slots, slots that run in serpentine lines or individual holes can also be provided. The structures are preferably not formed through the wood material, ie they represent recesses but not through holes. Due to the diagonal laying of the wooden layers, endless panels can be produced mechanically, the wooden components ultimately produced, for example wooden panels, prefabricated elements for houses or the like, being by far more statically stable due to the diagonal laying. In addition, the present invention offers economic advantages due to the possible endless plate production.

The components according to the invention have at least one blank which is provided with a structure at least on one side and / or in regions, the structure preferably being able to be formed as a grooving. The structuring or grooving on the wooden layers can be either exactly or unguided, or incorporated offset. The structures on one surface of a wooden structural element can be offset from the structures on the other surfaces of the wooden structural element, run at an angle to these or differ in some other way. Measures of this type further improve the stability of the otherwise very light wooden structural element according to the invention, it also being possible to dispense with the at least partial failure or foaming of cavities, in particular due to the structuring. A more differentiated glue application is also made possible.

The various layers of wood or their boards can be arranged diagonally at an angle of approximately 30 to 75 ° to one another, with angles of approximately 45 ° to 65 ° being preferred. The grooves or the structure of the wood layer can run approximately at the same angles or can also be provided with angles that differ from this.

It is also advantageous that, according to the invention or innovation, center plates between the at least two wooden layers can be dispensed with, so that intermediate layers which are expensive in terms of material can optionally be omitted. The wooden structural element designed according to the invention, in particular with diagonally laid wooden layers, enables a much better adaptation of the panel thickness to structural aspects.

There are particular advantages if the structure is at least partially provided with a preferably foam-like filler, as a result of which the insulation values can generally be improved.

A large material disadvantage of wood, namely swelling and shrinking, is largely compensated for. A change in length due to moisture or temperature changes essentially only takes place in the wood fiber direction. If the grain of different wood layers is different and these wood layers are attached to each other, e.g. by gluing, shrinkage or swelling of the wooden building element is strongly inhibited. A major disadvantage of the material wood, which leads to the formation of gaps between the individual blocks, especially in log houses, is thus eliminated.

The grain of wood in the layers of wood that follow one another can differ. Accordingly, from three layers of wood, for example, at least two different wood fiber profiles should have in order to be able to compensate for the shrinkage characteristics of the wood in an advantageous manner.

Advantages of the invention also lie in the fact that, on the one hand, the known advantages of wood, e.g. good heat and moisture storage capacity, high strength values and high thermal insulation capacity are maintained and, moreover, the negative properties of the wood, such as poor sound insulation capacity and high weight, are avoided or reduced.

According to the invention it is also achieved that the recyclable, naturally renewable, C0 ₂ -binding, in short, extremely environmentally friendly material wood in construction sen can be used more versatile and can be used instead of other, less environmentally friendly and difficult to work with building materials. The wooden construction element according to the invention can also be used in the manufacture of doors, furniture, etc., in particular as a door panel, etc.

Advantageously, greater stability is achieved through an increasing number of layers of wood. This makes it possible to process wood that is normally not suitable for normal use for construction purposes. This means that extremely weak wood, recycled wood or firewood can also be used. According to the invention, birch, beech or oak wood as well as wood which is produced as a marginal product or as an excess in the sawmill during production can also be processed.

However, it is preferred to process approximately 18 to 24 mm, in particular approximately 20 to 22 mm, thick boards according to the invention, since such wooden materials are generally available (e.g. for Euro pallets etc.).

If necessary, it could also be regarded as independently inventive to fill the conventional wooden structural element with the largely biological filler at least partially.

For gluing the wood layers, for example, types of urea resin, types of resorcinol resin, types of melamine resin or polyurethane glue can be used, the latter being preferred.

The individual elements that make up the wood layers are cut from fresh, green wood or from pre-dried raw material. According to the invention, these blanks are provided with structures, such as, for example, a plurality of longitudinal or transverse grooves or cracks. A structure is generally understood to be a plurality of depressions which are introduced into the blanks, for example by means of sawing or milling. The structure is preferably elongated and rectilinear. If necessary, however, it can also be curved or branched his. The grooving can have, for example, rectangular, trapezoidal, round or oval grooves.

The structure of the blanks prevents deformation of the wood during storage or the final drying of the blanks, so that the reject rate is minimized. This is a major advantage over the known wooden building elements.

The structure also results in significant weight savings compared to solid wood, without significantly reducing the stability of the wooden board. The weight saving is, for example, approximately 30%. The weight saving makes it possible to pack the structured blanks more tightly and to dispense with gaps or voids between the blanks. The result of this is that, compared to the prior art, greater stability is achieved with approximately the same weight saving compared to solid wood. Furthermore, better wooden insulation and insulation properties are achieved due to the closely spaced wooden layers.

The structuring of the wood, e.g. in the form of a large number of longitudinal or transverse grooves also has the advantage of better heat or cold insulation compared to only a few large spaces, since the mobility of the enclosed gases or the enclosed air is considerably reduced. In addition, the large number of different chambers that result from the structuring prevents effective sound propagation.

A wooden component designed according to the invention, which has at least four, preferably five or more layers, is particularly advantageous. Such a Holzbauele¬ element has laterally and / or upward and downward tongue and groove designs. Wooden construction elements designed in this way, which can have roughly the dimensions of masonry stones, can be easily inserted into one another, connected to one another, for example, via mortar, concrete, adhesive or wood glue, and can be used extremely advantageously for construction purposes in this way. If such wooden building elements or bricks are arranged in a composite, that is to say built up, for example, in the form of a wall, it is particularly advantageous if the layers and / or their corrugations run differently, preferably in the opposite direction. In this way, individual cavities that result from the enclosed grooving can be closed off from one another, which results in better thermal insulation properties. On the other hand, such structures made of wooden structural elements can be particularly stable and free of distortion with regard to their statics due to the different layers and / or grooves.

Of course, the stability of a building part constructed from wooden building elements according to the invention does not suffer significantly from the fact that successive wooden building blocks or elements have layers whose course to one another is identical to the course of a preceding or subsequent wooden building block or element.

In order to be able to advantageously achieve a better bond of the wooden structural elements with one another and a better stability of the wooden structural elements with one another, it is advantageous if the tongue-like or tongue-like formations in the composite successive wooden structural elements relative to the direction of formation of the layers or scoring on different or opposite Pages are provided.

The grooves or the structures can also be incorporated into the wood layers in a direction deviating from the vertical to the layer or board surface. Two such adjacent surfaces of two successive layers thus result in a cross section of a herringbone pattern, which has the advantage that the grooves, which run obliquely to the surface, allow them to be deeper. As a result, more material can be removed from the individual layers of wood relative to the surface. As a result, the thermal insulation value rises considerably and the structures in successive layers can be better insulated from one another when connecting successive layers of wood. If wooden construction elements or bricks according to the type explained above are advantageously used, groove designs can be partially recessed in order to produce integral cavities in the construction of a part of the building, through which electricity or water pipes or the like can be laid.

The structures of the blanks also advantageously have unevenness and fringes, which are produced when the structures are sawed out or milled out. This surface roughness in conjunction with the foam-like filler, which at least partially fills the wooden structural element or the structures according to the invention, results in a greatly increased contact area between the filler and the wood. Since this filler is advantageously binding, i.e. contains glue-like components, this leads to a considerably improved stability of the wooden component compared to the prior art, since only smooth blanks are glued there.

The filler also significantly increases the sound damping properties and the insulation properties of the wooden component. Large cavities have the property of forming cold bridges. The structuring makes it possible to keep the cavities as small as possible and thus almost nullify their cold bridge property and still maintain the advantages of the cavities, namely a lower weight of the wooden component, material savings and the insulating properties of the air. The filler now again considerably strengthens the insulation properties of the wooden structural element and thus leads to good insulation, but above all also to good sound insulation values of the wooden structural element according to the invention.

A foam-glue mixture or possibly a filling mixture that is as far as possible organic is to be preferred as the filler. For example, a glue containing or consisting of lignin can be used.

The more wood layers are combined to form a wooden construction element according to the invention, the more the advantageous properties, such as stability, insulation, tion properties and sound insulation. The stability is achieved by a large number of closely adjacent and superimposed blanks with different wood fiber directions. The weight saving and the better sound insulation and insulation properties result from the large number of chambers or structures which are filled with a filler and are not connected to one another. In this way, according to the invention, an easy-to-work construction material with almost ideal properties is obtained from a natural product.

According to one embodiment of the invention, at least one of the two outer wooden layers is designed as a so-called cover layer. A top layer consists of at least one blank, which can only be provided with a structure on the flat side pointing into the interior of the wooden structural element. On the opposite, flat, outward-facing side, this top layer is planed, scrubbed, brushed etc. in order to achieve the smoothest possible surface.

Instead of these cover layers, non-structured blanks or thin boards (thickness e.g. 6 mm) can also be used. The outer layers of wood can e.g. also be formed in only one specific type of wood and / or in a specific wood fiber direction in order to achieve the most advantageous optical impression possible.

The wood fiber directions of the blanks forming a wood ply advantageously run parallel to one another at least in regions. This makes it easier to achieve in the manufacture of a wooden component according to the invention that the wood fiber direction of adjacent wooden layers is essentially perpendicular to one another. This effectively counteracts swelling or shrinking of the wooden component, while at the same time increasing the stability of the wooden component.

The structure running approximately parallel or approximately perpendicular to the grain, which is formed, for example, in the form of grooves or crevices or other types of depressions, also allows a wooden structural element to be constructed as simply and clearly as possible. Advantageously, the individual blanks are close to one another, in order to avoid additional larger gaps in addition to the structures and to ensure a high stability and compactness of the wooden structural element.

As a rule, the blanks are boards, such as thin boards with a thickness that can be less than 1 cm, but are preferably in a thickness range of 18 to 24 mm. As a result, the wood component can have more wood layers with the same thickness than if it were assembled from thicker blanks. A higher stability is thus achieved. In addition, the number of chambers or structures that are not connected to one another and thus isolating or insulating increases. In addition, it is avoided that a particularly deep structuring of the wooden components has to be carried out in order to achieve sufficient weight savings.

The insulating material preferably has good stability and very good heat, cold and noise insulation properties. As a rule, the insulation together with a glue forms a foam-like filler that connects the wood layers or the blanks. The insulation material can also consist of a cellulose mass.

The glue is preferably a one-component adhesive, in particular a formaldehyde-free and CFC-free polyurethane adhesive. The glue can also be a glue on a natural basis or a multi-component adhesive.

Of course, the raw material for producing different cuts in individual layers of wood can be the same or different in cross-section and quality.

The wooden components are advantageously provided on their lower and / or upper end faces with connection profiles for connection to a floor or ceiling threshold. The connection profiles are preferably formed on the outside in order to overlap the threshold. In order to connect the wooden components to one another, they preferably have a tongue and groove in the longitudinal direction of the wood fiber or else transversely. The individual Holzbauele¬ elements are glued together with glue and / or connecting elements so that they are largely close to each other or even interlocking. A large number of individual interlocking wooden components thus results in a tight and stable connection of a composite wooden component.

A wall made of various wooden building elements can thus be made windproof. However, due to the special properties of the wood and the damping material, it is breathable.

If necessary, installation lines or cavities for receiving installation lines can be incorporated into or provided in the wooden structural element during manufacture. This ensures extremely efficient and therefore economical cabling on the building itself. This also has the great advantage that all cables, lines, etc. can be changed, relocated or expanded at any time without having to cut, drill or change anything on the walls. The same applies of course to the sanitary lines, such as gas, water, heating, ventilation, telephone / fax and satellite lines. Lines are preferably provided according to the European standard system (s).

The wooden construction elements are particularly advantageously designed in various prefabricated grid sizes. This makes it possible, in the manner of a modular principle, to create any wall and ceiling size quickly, efficiently and easily through easy installation. The dimensions of the wooden building elements differ, but as a rule they are made to the octametric system of the masonry grid - i.e. an eighth meter - and are dimensioned to be manageable in terms of weight and size. Your area of application is diverse. So they can be used as floor, ceiling or roof panels, as well as a partition or bulkhead. In addition to use for all types of buildings, such as Residential buildings and public buildings, even the wooden building element according to the invention is ideally suited for half-timbered buildings.

Of course, the wooden component according to the invention can also be designed as a corner or transverse component. This also makes final assembly easier.

It is also possible to design the wooden construction element in a curved shape. For this purpose, the blanks forming the wooden layers are assembled according to a special system, which results in a curved or curved shape of the wooden structural element. This creates special design options, e.g. when building a building.

It is also conceivable to construct the wooden construction elements in a mixed construction with plastic, other recyclable or natural construction products. By combining different types of building materials with the wooden building element according to the invention, the properties of the wooden building element, e.g. Sound insulation properties, thermal insulation properties or heat capacity properties can be influenced or controlled in a targeted manner.

Of course, walls made from the wooden construction elements according to the invention can be made from the outside as well as from the inside with any materials, such as Plasterboard, wallpaper, colors, etc., are provided in order to change both the optical properties and the material properties of this wall.

It can be seen from the preceding sections that the advantageous design features in combination with one another or with the features according to the invention make a considerable contribution to solving the problem on which the invention is based, in a surprisingly advantageous manner, since the thermal and acoustic insulation values are improved in an unexpected manner , The freedom from deformation and the mechanical stability of the components according to the invention additionally catch the eye. It is particularly advantageous that green, fresh raw material or wood or, if appropriate, predried raw material can be used according to the invention for the production of the blanks, so that shrinkage or deformation both in length and in width can be virtually ruled out. Then the raw material or wood is provided with structures, for example in different variations. The wood can then be subjected to a preferably biological drying process. This results in the possibility of an extremely ecological and economical outdoor drying and then requires only a small amount of time and money for the final drying during the final processing. A major advantage is that this type of drying of the already structured blanks prevents the wood from being deformed or twisted when stored appropriately. This significantly minimizes the reject rate. The wood does not have to be stacked and dried by conventional, complex processes, but has so many channels through the grooving that the wood can dry itself very well in the natural process (air drying).

After the individual layers of wood have been glued, the wooden construction element is cut exactly to size and in particular milled all around, the milling being carried out in such a way that any residual glue in the tongue and groove area is removed. The outer edges are also chamfered so that the neighboring elements can be joined quickly and easily. This precise prefabrication of the wooden elements virtually eliminates wall unevenness and a substructure, such as a slatted frame, etc., for planking to be applied is therefore not necessary for both the inside and the outside.

Insofar as the same reference symbols are used in the various exemplary embodiments which follow, these designate identical or functionally identical components.

1 shows a particularly advantageous wooden component according to the invention. This has diagonal wooden layers 10 ', 10 ", 10"'. These are connected to one another in the finished wooden construction element, for example by press gluing. The grooves 12a, 12b, 12c of the wooden layers 10 ', 10 ", 10"' can also run diagonally, the course of the grooves being able to go hand in hand with the course of the wooden layers 10 ', 10 ", 10"' and / or the grooving 12e can run in a different direction, such as the wood layer 10 "'itself or the wood fibers of the wood layer 10"'. However, for reasons of production technology, it is preferred if the structuring or scoring runs at least substantially parallel to the longitudinal edges of the wooden layers or their cuts.

The grooves can also be interrupted so that they are in the form of individual slits arranged in a row or separate, but which do not pass through the board material. The individual slots have the advantage that the slots in the wooden component form individual closed air chambers. The slots can also be arranged crosswise or offset. Slots in connection with holes or holes alone can also be provided as a structure.

Due to the diagonal course it is possible on the one hand to manufacture these wooden building elements infinitely and on the other hand the shrinkage behavior and the stability is influenced very positively. It can also be diagonally aligned with the wood layers Groovings 12a-c take place to the extent that air exchange takes place in such a way that walls made of these wooden building elements are well ventilated, but not to the extent that heat transfer could take place.

Filling the grooves 12a-c with a foaming filler is not necessary, but can be an option.

2 additionally shows that the grooves 12a-c of wooden layers 10 ', 10 ", 10"' lying parallel to the wood layers can overlap one another and / or can partially overlap or come to lie one on top of the other.

3 and 4 show wooden layers 10 and 10 ^v with a "herringbone pattern". The grooves 12d, 12e have an angle of inclination to the flat surface of the wooden components 10 ™, 10 ^v . As a result, the grooves can go less deep into the wood material at the same depth, so that thinner boards can be used for the wood layers. Here, too, the wooden layers 10 ™ and 10 ^{v can be laid} diagonally or vertically, if necessary in parallel, the grooves advantageously, as can be seen from FIG. 4, run essentially parallel to the longitudinal edges of the wooden layers or their boards.

All angles are suitable for diagonal laying, in particular between 35 and 85 °, preferably between approximately 50 and 70 °.

5 shows a side view of a blank 24 of a wooden component according to the invention, as can be arranged in particular on its surface. This blank is provided with a structure on one side. This structure is designed in the form of trapezoidal grooves 12 which run perpendicular to the smooth surface 26 and are parallel to one another and which in principle can have any desired geometry. Wooden prongs can be produced on the walls of the grooves, which can bring about a stronger connection between the structured blank 24 and a filler 22 not shown in this figure. If this blank is used as a top layer, it is advantageous to use it To process surface 26 by planing, scrubbing or brushing etc. in order to achieve the smoothest possible outer surface. Web-like sections 14 have remained between the grooves 12.

The wood plies can be laid diagonally, in particular in the direction of the fibers, whereby the grooves can be aligned equally or differently.

The structure or grooves do not necessarily have to be filled with insulating material or a foam-like filler, since the air in the grooves 12, 12 'is also insulated and, due to the small dimensions, can hardly or not at all circulate.

6 shows a side view of a blank 24 structured on both sides. In this case, trapezoidal or funnel-shaped grooves are introduced on both sides perpendicular to the two broad sides of the blank 24. The grooves go so deep that only a narrow core 16 of the blank remains, which is preferably smaller than a third of the blank. Here, too, frayed wooden prongs can be provided, which favor a firm connection with the foam-glue mixture filling the wooden structural element.

For example, as shown in FIG. 7, three structured blanks 24a to 24c arranged next to one another can be connected to one another. Because only one at a time. Blank 24 can form a wood layer 10, these three blanks 24a to 24c can also be understood as wood layers 10a to 10c. The blanks can also be incised in the shape of a herringbone or provided with grooves 12 'with a trapezoidal shape. The directions of the blanks 24a and 24b roughly predetermined by the herringbone shape could run in opposite directions, whereas the directions of extension of the blanks 24b and 24d could run parallel to one another.

8 shows five blanks 24a to 24e superimposed on one another. The structure can be seen in the blanks 24d and 24b. Again, trapezoidal depressions 12 were introduced perpendicular to the broad side of the blanks 24b and 23d. The cuts 24a, 24c and 24e can be provided with a structure. However, it can also be unstructured blanks. One or more grooves 13 can be provided on the edges, which are used for connection to other blanks or wooden structural elements. The individual blanks 24a to 24e can in turn represent wooden layers 10.

FIG. 9 shows a wooden component 28 in which each of the wooden layers 10 consists of only one blank 24a to 24e. The wooden component is at least partially filled with a filler, preferably a foam-glue mixture 22. This largely fills the cavities resulting from the depressions 12.

FIG. 10 shows a perspective view of a foamed wooden structural element 28. It can be seen here that the wooden layers 10a and 10e are designed as cover layers. They are therefore only structured on one side. The intermediate wooden layers 10b to 10d are provided with a structure on two sides. The cavities of the wooden component are filled with the filler 22.

11 shows two wooden components 28a and 28b, which have a groove device 13 and a spring device 13 '.

12 shows a side view of a wooden component 28 with an installed installation pipe 30. This installation pipe is embedded in the filler 22 between two non-structured cover layers 18. The installation pipe 30 lies / in a wood layer 10 formed by the cuts 24a and 24b.

FIG. 13 shows a side view of a wooden structural element 28 constructed in a mixed construction with plastic. The two wooden layers 10a and 10b lying in the middle each consist of two blanks 24a and 24a 'or 24b and 24b'. The plastic 32 is located between the blanks of a wooden layer. The two cover layers are formed from unstructured boards 18. It would also be possible to join blanks into corner elements. For example, three composite blanks could form a curved or curved layer of wood. At the connection points, they could be connected by suitable connection devices. Rectangular channels or grooves could form depressions that run perpendicular to the plane predetermined by the curvature.

FIG. 14 again shows a very particularly advantageous embodiment according to the invention, in which the wooden ^layers 10 ^VI , 10 ^vπ , 10 ^v are laid diagonally to one another in order to form a corresponding wooden ^{structural element} together. The grooves 12a, 12b, 12c run essentially parallel to the longitudinal edges of the wooden ^layers 10 ^VI , 10 ^vπ , 10 ^Vffl or to the longitudinal edges of the wooden boards from which these wooden layers are constructed. A sectional illustration of the embodiment according to FIG. 14 could be seen in FIG. 2. The embodiment according to FIG. 14 could also be provided with the "herringbone" grooves shown in FIG. 4. The wood ^layers 10 ^VI , 10 ^, 10 ^vπι are connected to each other, for example by a press gluing. This embodiment is particularly suitable for continuous processing or manufacture.
