The invention relates to a structural element of wood, consisting of at least two layers of wood, where at least one layer is made of at least one workpiece having at least one side and/or on individual sections of the structure in the form of grooves and/or slots. Such structural elements of the wood is so

Structural element from the wood of this type is already known from G 9207654.8. Structural element includes at least five layers, which are located in parallel planes and arranged in the form of a lattice. Using this design achieves good stability and a certain reduction in shrinkage, which allows the use of waste wood from the slabs for the manufacture of such elements. The middle layer consists of spaced from each other at a distance in the transverse direction of the bars, boards or similar Through these periods of voids, which, on the one hand, lead to a weight reduction item, but, on the other hand, represent the zone of penetration of cold or heat. The disadvantage is the low coefficient of sound insulation achieved by using the specified type of structural element of wood. Another disadvantage is that the boards or timbers at the easy drying cracks, resulting in boards or bars they wear out and can no longer be used for the manufacture of structural element.

Other structural elements of wood or finish building blocks of wood known from the G known to the invention is described in DE-C-835646 structural element in the form of boards of several layers of wood, equipped with at least one side defined structure representing the slots passing longitudinally layers of wood, or boards, which consist of layers of wood. However, the manufacture of these structural elements is relatively time consuming and requires a major commitment of time, because it is impossible to produce flow-continuous method. In this case, the continuous production excluded because the use of available boards with defined dimensions results in certain sizes known structural elements of the wood. In other words, depending on the standard size boards always get a structural element having a certain length.

Thus, the objective of the invention is to eliminate the disadvantages of the known prior art and to develop a constructive element of wood with high coefficients of heat and sound insulation, which could simply produce in mass production, in particular, flow-continuous method, while reducing waste.

Underlying the invention the task is solved by the structural element of the bottoms of at least one workpiece, which at least one side and/or on individual sections provided with a structure in the form of grooves and/or slots. According to the invention the structural element is a building block, in which layers of wood are located diagonally to each other and the grooves and/or slots layers patterns are also diagonally evenly from each other.

While the structure of the structural element can be filled at least partially of foam filler.

In a preferred form of implementation of at least one outer ply of wood made in the form of cladding coatings and/or at least one flat blanks.

Preferably also, the layers of wood were placed diagonally to each other at an angle of between 30oup to 75opreferably from 45oup to 65o.

It is advisable in a constructive element according to the invention the grooves of the patterns to be arranged in parallel or perpendicular to the direction of wood fibers, and the grooves of the patterns with respect to the surface layer of wood should be placed at an angle other than directly in order to obtain a picture of the "Christmas tree".

Preferably construce each other.

On the lower and/or upper end edges of the structural element is advisable to make connecting profile for connecting it with the tying floor or ceiling and so that this profile had a ledge on the outer side, which is tying the floor.

Along the perimeter of the structural element it is also advisable to have a tongue and groove oriented in the direction of the wood fibres, and the element can be embedded wiring or there are voids to strip the transaction.

Preferably, when the structural element has four or five layers on the sides and/or top and bottom would be provided with a profile element type groove or ridge.

While layers and/or grooves in the United together structural elements according to the invention are in different, preferably in opposite directions.

Preferably the core elements of the type of groove or ridge in United together structural elements of wood to run on different or opposite sides relative to the direction of the layers or grooves.

Achieved according to the present invention advantage is based on the fact that the constructive element of others who use them diagonally to each other, moreover, the structure of the grooves preferably is virtually parallel to the longitudinal edges of the layers of wood, or boards, of which they are made. However, the structure may also be diagonally towards that direction or deviation from the diagonal, parallel or crosswise. Individual grooves may also be arranged sequentially in a row or offset relative to each other, crosswise, or in a different order. Can also be provided zigzag grooves, the grooves in the form of wavy lines or even individual holes. With this preferred structure, which do not pass completely through the wood, i.e. represent indentations, but not through holes.

Thanks diagonal stacking layers of wood becomes possible machinery manufacturing endless panels, and made thus structural elements of wood, such as wooden panels, ready-made building blocks for houses, etc. due to its diagonal styling are statically more stable. In addition, due to the ability to make endless panels of the present invention allows to achieve certain advantages in economic terms.

As already mentioned, the different layers of wood, or boards, of which they are composed, can be positioned at an angle to each other from approximately 30oup to 75opreferably from 45oup to 65o. The grooves or patterns in the layer of wood can be located approximately at the same angles, and at different angles.

Even agnostini between at least two layers of wood, so if you want you can not apply the intermediate layers, which takes a large amount of material.

Made in accordance with the invention, a structural component of wood allows much better to satisfy the requirements in relation to the strength of the panels from the point of view of building physics.

Particular advantages are achieved if the supply structure at least some parts preferably foam filler, which can improve the sound insulation factor.

In large part, to compensate for the significant disadvantages of wood as a building material, namely swelling and shrinkage. Change of dimensions due to moisture or temperature occurs practically only in the direction of the wood fibers. If different layers of wood have different texture and these layers of wood bonded together, for example by means of glue shrinkage or swelling of the structural element of wood is largely limited. Due to this resolve significant disadvantage of wood as a building material, which leads, in particular, in the si layers, alternating with each other, may vary. As a result, for example, of three layers of wood at least two must be distinguished from one another arrangement of fibers that provides the most simple compensation of the shrinkage characteristics of wood.

The advantage of the invention lies in the fact that, on the one hand, remain well-known advantages of wood, such as, for example, good ability of heat storage and moisture absorption, high strength factor and heat-insulating characteristics, and, on the other hand, are eliminated or reduced negative properties of wood, such as poor sound insulation and a lot of weight.

In addition, thanks to the invention is achieved that recyclable growing in natural conditions, binding of CO2in other words , absolutely non-polluting material, which is wood, you may find wider application in construction and can be used instead of other, less committed against pollution and more difficult construction materials.

Another advantage is that by increasing the number of layers of wood can achieve a higher sustainability. You can handle those sorts of wood, which, as a rule, usually do not find wide application for construction purposes. This means that you can use very weak wood, re-used wood or firewood. In accordance with the invention it is also possible to use the wood of birch, beech or oak, and the wood in the form of slabs or waste when cutting.

Obviously, in accordance with the invention, it is preferable to process the boards of a thickness of approximately 18 to 24 mm, especially from 20 to 22 mm, since such wood material is widely available (for example, is used for europallet and so on).

Under certain conditions, you can also consider filling at least partly common structural element from wood of different materials of biological origin.

For bonding layers of wood you can use, for example, varieties moonvine-formaldehyde resin, grade adhesive-based resorcinol resin, grade melamine-resin glue or polyur the LOI, cut from raw wood or pre-dried raw materials. These are preset in accordance with the invention structure, for example they do a large number of longitudinal or transverse slots or grooves. Under the structure usually see a large number of pits, which are performed on the workpiece, for example, by sawing or milling. The structure should preferably have an elongated and rectilinear form. However, if necessary it can also be curved or branched. The grooves in the cross-section can be, for example, rectangular, trapezoidal, circular or oval.

The structure of the workpiece prevents the deformation of the wood during storage or final drying of the workpiece so that due to this reduced the scrap rate. This is a significant advantage compared with the known structural elements of the wood.

Using structuring, in addition, achieve a significant weight saving compared to the wooden elements of solid section, without affecting significantly the sustainability of wooden planks. The weight savings is, for example, approximately 30%. Due to the weight saving is in the terrible or emptiness. The consequence of this is that greater stability in comparison with elements made by traditional methods, with approximately the same weight saving with respect to elements that have a solid cross-section. Further, due to more snug fit to each other adjacent layers of wood compared with elements manufactured by traditional methods, achieve improved sound insulation.

In addition, the advantage of the structure of wood, for example, in the form of a large number of longitudinal or transverse grooves in comparison with a small amount of a single large gaps is to improve the insulation, since the mobility of a prisoner in an enclosed space gas or air is significantly reduced. In addition, a large number of different cavities, which are formed in the structure effectively prevents the propagation of sound.

Most preferred is executed in accordance with the invention, a structural component of wood that has at least four, preferably five or more layers. Such a constructive element of wood is provided on the sides and/or top and bottom prof the ins, which may have a size approximately corresponding construction bricks can easily be inserted into each other, connect with each other with mortar, concrete, glue or adhesive for bonding wood, so they are most preferably used for construction purposes.

If such structural elements or blocks of wood are combined in a single structure, i.e., for example, build in the form of a wall, it is particularly preferable when the layers and/or grooves are in different, preferably in opposite directions. This way you can isolate from each other the individual cavities, which are formed in closed grooves, thereby achieving the best possible insulation. On the other hand, such structures are composed of structural elements of wood, at the expense of located in different image layers and/or grooves can be very resistant to static characteristics and not be skewed.

Of course, the resistance of parts of buildings, built of structural elements of wood according to the invention, may be irrelevant to deteriorate due to the fact that the profile of the layers following each other constructive blockage structural unit or element.

To improve the connection between the structural elements of the wood and enhance their sustainability is most preferable to arrange the profiles of the type of pile or ridge of successive structural elements of wood at different or opposite sides relative to the direction of manufacture of the layers or grooves.

The grooves or patterns can also be performed in a direction other than perpendicular to the plane of the layers or boards. Two such adjacent surfaces of two adjacent layers together form the cross-section drawing of type "tree", the advantage of which is that the grooves passing obliquely relative to the surface can be more tightly superimposed on each other. Therefore, the surface of the individual layers of wood can be removed more material. Due to this substantially increases the coefficient of heat insulation and structure of successive layers of wood at their mutual connection is better isolated from each other.

If you mostly use the structural elements of wood or blocks of the above type, the design of the tongue can be made somewhat more recessed, centroproizvod or water or etc.

In addition, it is preferable that the structure of the billet had rough edges and burrs, which can be easily obtained by cutting or milling patterns. These irregularities on the surface in combination with a foam filler, which at least partially fills the structural element or the structure according to the invention significantly increase the contact area between the filler and wood. Since this filler mainly contains a binder, i.e., adhesive components, this leads to a significantly higher stability of the structural element of wood in comparison with those manufactured in the traditional way, as in the latter case, glue only the workpiece with a smooth surface.

In addition, the filler is substantially improves insulating properties and thermal insulation characteristics of the structural element of wood. The feature of large cavities is that they form area of the penetration of cold air. However, structuring allows you to make void the maximum small size and thereby improve their thermal insulation characteristics while maintaining the advantages of voids, namely less weight is politely even more improves the insulating properties of the structural element of the wood and thereby provides good insulation and primarily also improves the sound insulation of this structural element of wood according to the invention.

As the filler, it is preferable to use peaklevel mixture, respectively, under certain circumstances, a mixture of fillers, which, to the extent possible, should contain biological products. For example, you can apply glue containing lignin or consisting of him.

The more layers of wood together in a constructive element according to the invention, the more the better such advantageous features as durability, insulation and soundproofing. Stability is achieved through the use of a large number of workpieces having different fiber directions and closely adjacent to each other laterally and tightly stacked on top of each other. The weight savings and improved sound and thermal insulating properties due to the large number filled with filler mesoeconomics each other cavities or structures. Thus, in accordance with the invention of a product having a natural origin, get easily processed construction and material with almost perfect features.

In accordance with one embodiment of the invention, at least one of the two outer layers on the which may be provided with a structure only on the side surface, facing the inside of a constructive element. The opposite flat side facing layer facing outward, handle on a planer, plane, sand, etc. to get a more smooth surface.

Instead of such a cladding layer can also be applied to unstructured workpiece, for example a thin plate (thickness of, for example, 6 mm). Layers of wood, outside, can also be performed, for example, from only one specific wood species and/or with one specific pattern of the fibers to provide the most aesthetic appearance of the product.

In a preferred embodiment, the fiber directions of the workpiece, forming a layer of wood, at least on some part thereof are parallel to each other. Due to this, in the manufacture of structural element of wood according to the invention is easier to make the direction of the fibers of adjacent layers of wood were almost perpendicular to each other. This makes it possible to effectively counteract the swelling or shrinkage of the constructive element of wood, at the same time, you can improve its stability.

Proh, the example in the form of grooves, the grooves or recesses of a different kind, also provides the most simple and clear making constructive element of wood. Individual blanks are preferably fitted tightly to each other, to thereby eliminate the existing next to the structure, significant additional intermediate space and to ensure high stability and compactness structural element of wood.

As a rule, preparations are boards, for example, thin boards, which can have a thickness of less than 1 cm, but preferably the thickness ranges from 18 to 24 mm. due to this structural element can have more layers of wood with the same thickness, than one made of thicker workpieces. Thus attain greater stability. In addition, an increasing number of unconnected with each other and therefore performing heat - and sound insulating function of cavities or structures. In addition, there is no need to produce in a constructive element of the wood structure with a very deep profile to achieve sufficient weight saving.

Insulating material before the usually insulating material together with the adhesive forms a foamy, bonding layers of wood or billet filler. The insulation material may also be composed of cellulose.

Preferably the adhesive is a one component adhesive, in particular polyurethane adhesive that does not contain formaldehyde and FCKW (fluorine - and chlorine-containing hydrocarbons). The adhesive may be a glue, natural-based or multi-component adhesive.

It is obvious that the raw materials for the manufacture of various preparations in a separate layer of wood can have either the same or different sizes and quality.

Preferably, the structural elements of the wood had on their upper and/or lower end sides of the butt profile to connect with tying floor or ceiling. Preferably, this profile had a protrusion for coupling with the beam overlap.

To connect structural elements of wood, they should be on the edges of the fitting type of groove and ridge in the direction along the grain or perpendicular to them. Individual structural elements of the wood adjust to each other with glue and/or soeding other. A large number of individual incoming into each other constructive elements of the wood thereby forms a tight and stable connection of these elements in the design.

Thus, the wall of the various structural components of wood can be made resistant to wind load. However, however, it "breathes" due to the special properties of wood and insulating material.

If necessary, in a constructive element of wood you are already at the production stage to make different types of transaction or to provide a cavity for routing transactions. Because of this, when the construction ensures the most efficient and therefore economical cable network. It has a great advantage, because at any time you can replace all the cables, wires and so on, build new or to expand it, no cutting, no drilling or not changing for this purpose, anything in the wall. Of course, the same applies to sanitary-technical equipment, such as gas, water, heating system, ventilation channels, telephone/Fax lines and lines of satellite communications. Preferably, the wiring and piping to perform in accordance with Europe is wood in the form of modules of different sizes. Consequently, this technology can be applied to the modular principle, i.e. by easy installation quickly, efficiently and easily manufacture the walls and ceilings of all sizes. Structural elements made of wood with different dimensions, typically using accumetrics measurement system for a modular grid used in masonry, i.e. Falmer and thereby gain the comfortable weight and size. The scope of structural elements is very wide. So, they can be used as floor panels, ceiling or roof, and walls or bearing walls. In addition to applying for all kinds of buildings, such as residential and administrative buildings, a structural component of wood according to the invention is also suitable for frame structures.

It is obvious that structural component of wood according to the invention can be made in the form of angular or transverse structural element. Due to this also facilitates the final Assembly.

Similarly constructive element of wood can be given a curved shape. To this end, the workpiece, forming a wood layers, connected by a special system,opportunities for design, for example, in the construction of buildings.

Structural elements of wood can be produced in the form of mixed designs using synthetic materials, and other reusable building materials or building materials of natural origin. By combining different building materials with a constructive element of wood in accordance with the invention can be targeted to influence or regulate characteristics such as, for example, soundproofing, heat insulation or characteristics of the heat capacity.

Of course, the walls made of wood structural elements in accordance with the invention, both outside and inside can be finished with any material, such as, for example, gypsum boards, Wallpaper, paint, etc. to change thereby the appearance and characteristics of the construction material of the wall.

From the foregoing it is obvious that the preferred embodiments of the invention largely contributes to effectively solve the underlying problem, since the unexpected fact is that you can improve the odds t the mechanical stability of the structural element in accordance with the invention.

A special advantage is that for the manufacture of preparations in accordance with the invention can be used swiezegowno raw materials or wood, or if necessary, pre-dried raw materials that can virtually eliminate shrinkage or deformation both in length and in width. In accordance with this raw material, or wood, attached structure, such as a different type. Thereafter wood can be preferably biological drying process. This allows extremely ecological and economical drying in the open air, in the final processing then require only a small investment of time and funds for final drying. A significant advantage of this is that such drying is already structured procurement prevents deformation or shrinkage of the wood if properly stored. Due to this significantly reduced the percentage of culling. Wood is not required to stack and dry the traditional labor-intensive methods, and in contrast, the result of structuring it has such a number of slots that it may itself very well to dry in attestment cut exactly to size in particular handle on the perimeter of the cutter, the milling is carried out in such a way as to remove the area of the groove and ridge are possible existing adhesive residue. Also chamfer on the outer edges to the adjacent elements can be easily and quickly customized to each other. As a result of such high-precision preparation of wood elements are practically eliminated the roughness of the walls and do not want to put wood on the supporting structure, such as a crate or with internal or external parties.

Other advantages of the invention will be better understood from the following description of its preferred embodiments with reference to the accompanying drawings, where

in Fig. 14 is a bitmap image of the structural element of wood diagonally opposite to each other workpieces or layers of wood.

In that case, if the description of the various examples of implementation are the same legend, they represent olny structural element of wood in accordance with the invention. It is located diagonally relative to each other woody layers 10', 10", 10"'. In the finished structural element they are bonded together, for example, by gluing under pressure. The grooves 12a, 12b, 12c wood layers 10', 10", 10"' can also be diagonal; the arrangement of grooves may coincide with the location of the layers 10', 10", 10"' and/or grooves 12c can pass in the other direction, i.e. in the direction of the layer 10"' or in the direction of the wood fibers 10"'. However, from the point of view of manufacturing technology, it is preferable to perform the structuring or grooves almost parallel to the longitudinal edge of the wood layers or pieces.

The grooves can also be intermittent, so that they may be placed in a separate line or separate slots, which, however, do not pass completely through the Board material. The advantage of the individual splines is that they form in a constructive element of wood closed air chamber. The slots can also be arranged crosswise or offset relative to each other. As well as patterns can be provided by the slots in combination with holes or one hole.

Due to the diagonal of the races is Ecodom, on the other hand, to have a significant positive effect on the drying characteristics and stability. With slots 12a-c, the same way running diagonally with respect to the layers of wood, you can also get this kind of ventilation, so that the walls made of such wood structural elements, is well ventilated, but not to the same extent that it may be the heat transfer.

Filling the grooves 12a-c foam filler is not necessary, but can be considered as an option.

In Fig. 2 additionally shows that the parallel layers of wood grooves 12a-c are stacked on each other woody layers 10', 10", 10"' may overlap and/or may overlap only partly, or may be placed one above the other.

In Fig. 3 and 4 show the layers of wood 10IVand 10Vthat form a pattern of type "tree". While the grooves 12d, 12e are tilted with respect to the flat surface of the wood structural element 10IVand 10V. Due to this, the grooves having the same depth can log in to the wood less deeply so that for the manufacture of a layer of wood you can use thinner boards. In e the spine parallel to each other, while it is preferable that the grooves, as shown in Fig. 4, was held almost parallel to the longitudinal edges of the layers of wood, or boards, of which they are made.

When diagonal arrangement can be any of the angles, in particular lying in the range of 35oup to 85o, preferably in the range of 50oup to 70o.

In Fig. 5 shows the side view of the workpiece 24 wood structural element according to the invention, particularly showing the structure of its surface. On this workpiece structure made with one hand. This structure represents an arranged perpendicularly to the flat surface 26 parallel trapezoidal grooves 12, which in principle can have any geometry. On the walls of the grooves can be made burrs, which may contribute to a more durable connection of the structured preform 24 is not shown in this drawing, the filler 22. If this procurement is used as a cladding layer, preferably the surface 26 of the handle on a planer, plane or sanding to provide a smoother outer surface. Between the slots 12 left sections 14 in the disappearance of fibers, thus, the grooves can be oriented in the same direction or in different directions.

The structure or the grooves do not necessarily fill insulating material or foam filler, because the air in the grooves 12, 12' is also provided an isolated and due to the small size of these grooves can circulate only to a limited extent or not circulate at all.

In Fig. 6 shows the side view of a structured on both sides of the workpiece 24. In this case, on both sides perpendicular to both broad sides of the workpiece 24 is made trapeliopsis or funnel-shaped grooves. The grooves are of such depth that the whole remains only a smaller part of the core 16 of the workpiece, the size of which is preferably less than one-third of the thickness of the workpiece. In this case, it is also possible to envisage obtained by milling burrs that contribute to the lasting connection filling peaklevel mixture with wood structural element.

You can, for example, as shown in Fig. 7, to connect with each other three are located next to each other structured preform 24a-24c. Since in each case the woody layer 10 can be formed by only one workpiece 24, these three workpiece 24a is PA "tree", accordingly, the slots 12' trapezoidal shape. Define pattern "herringbone" patterns blanks 24a and 24b can be in opposite from each other directions, whereas the structure of the surfaces of the workpieces 24b and 24c may be parallel to each other.

In Fig. 8 shows five stacked on top of each workpiece 24a-24e. The structuring can be seen on plate 24d and 24b. In this case, the wide sides of the blanks 24b and 24d perpendicular to a direction made trapezoidal recesses 12. Workpiece 24a, 24c and 24e may be provided with a structure. However, you can also apply and unstructured procurement. On the edges can be provided by one or more grooves 13, which are used to connect with other workpieces structural element. Individual workpiece 24a-24e in this case can also be a wood layers 10.

In Fig. 9 shows the wood structural element 28, in which each layer 10 consists of only one workpiece 24a-24e. Structural element at least partially filled with a filler, preferably peaklevel mixture 22. It fills a large part of the cavities formed by the recesses 12.

In Fig. 10 shows axonometrics is executed in the form of cladding layers. Therefore, they have a structure with only one hand. Intermediate layers 10b-10d provided with a structure with two sides. Voids in a constructive element is filled by a filler 22.

In Fig. 11 shows two wood structural element 28a and 28b having the core element 13 of the type of sheet and profile element 13' type ridge. In Fig. 12 shows the side view of the structural element 28 with built-in tube 30 for the transaction. This tube is placed in the filler 22 between two flat facing surfaces 18. The tube 30 is located in the woody layer 10 formed pieces 24a and 24b.

In Fig. 13 shows a side view wood structural element 28 made in the form of mixed designs using synthetic material. Both woody layer 10a and 10b, located in the middle consist of two work pieces 24a and 24a or 24b and 24b'. Between pieces of wood layer is a synthetic material 32. Both cladding layer made of flat boards 18.

The shape of the workpieces can also be customized according to the shape of the corner element. For example, the three together work pieces can form a curved or curved wood layer. In places cochlin the s can dimple, perpendicular to the planes defined by the shape of curvature.

In Fig. 14 shows a preferred embodiment of the invention, in which the wood layers 10VI, 10VII, 10VIIIlaid diagonally to each other so that they together form the wood structural element. The grooves 12a, 12b, 12c are almost parallel to the longitudinal edges of the layers 10VI, 10VII, 10VIIIor longitudinal edges of the wooden planks that make up these wood layers. In Fig. 2 shows the cross-section shown in Fig. 14 variant embodiment of the invention. In the embodiment of Fig. 14 can also be provided, as shown in Fig. 4 slots with a picture on the riser. Wood layers 10VI, 10VII, 10VIIIconnected to each other, for example, by gluing under pressure. This option is more suited for a thread-safe continuous processing or manufacturing.
