Definitions
- the invention relates to a wooden component with wooden layers according to the preamble of Protection claim 1.
- a wooden component can be used for walls, ceilings or Roofs and the like of buildings, vehicles, etc. are used.
- 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 building element has at least five layers and has a rusty arrangement, crosswise and in parallel layers. This training will be a good one Stability and a certain freedom from shrinkage achieved, which also allows excess Use wood from wood edge products.
- a middle layer consists of side to side spaced strips, boards or the like. These distances result Cavities that lead to weight savings on the one hand, but on the other hand Represent cold or heat bridges. The poor sound is also disadvantageous insulation values achieved by this wooden building element. Another disadvantage is that cracks form very easily when drying the boards or strips, so that the boards or strips to committee and are no longer used for the wooden building element can be.
- From DE-C-835 646 is a wooden board as a component of layers Known members that has several layers of wood, at least on one side with a Structure are provided, wherein the structure is a grooving in the longitudinal direction of the wooden layers or boards that make up the wooden layers are.
- the wooden construction elements described here are only relatively difficult and cumbersome to manufacture, since it is not possible to make corresponding wooden building elements endless to manufacture. The endless production is prohibited here because of the existing and used boards with predetermined dimensions each to a specific one Dimensioning of the known wooden components lead, so that always at a distance from certain standard board dimensions a certain wooden building element with a certain length arises.
- the invention is based on the object in the simplest possible way with simultaneous Reduction of the reject of a wooden building element with high heat or To provide sound insulation values, which is particularly easy in mass production lets produce, especially lets produce endlessly.
- Wood component according to the invention can be produced endlessly if the at least two or more layers of wood are arranged diagonally to one another, the structure or the grooving preferably substantially parallel to the longitudinal edges of the wooden layers or the board that forms them.
- the structure can also be corresponding run diagonally or in a different way diagonally, parallel or crosswise. It can also individual slots in series or offset from one another, crosswise or in another Alignment should be provided. Also zigzag slits, slits in serpentine lines run or individual holes can be provided.
- the structures are there preferably not formed through the wood material, i.e. they provide Recesses but not through holes.
- endless panels can be produced mechanically, the wooden components ultimately produced, for example wooden panels, Prefabricated elements for houses or the like, due to the diagonal laying are static far more stable.
- the present invention offers due to the possible continuous plate production economic benefits.
- the components according to the invention have at least one cut that is provided at least on one side and / or in some areas with a structure, the Structure is preferably formed as a grooving.
- the structuring or scoring on the wooden layers can face each other either exactly or unguided, as well offset from each other.
- the structures on one surface of a Wooden components can add to the structures on the other surfaces of the wooden component be offset, run at an angle to these or otherwise differ. By such measures will increase the stability of the otherwise very light wooden component further improved according to the invention, which at least partially fails or foaming of cavities, in particular due to the structuring, too can be dispensed with. A more differentiated glue application is also made possible.
- the different layers of wood or their boards can be at an angle of about 30 to 75 ° to each other can be arranged diagonally, with angles of approximately 45 ° to 65 ° preferred become.
- the grooves or the structure of the wood layer can roughly match the run at the same angle or are also provided with different angles his.
- the wooden construction element designed according to the invention allows a much better adaptation of the panel thickness to building physics Points of view.
- the structure is at least partially with a preferably foam-like feeler is provided, whereby the insulation values in general have it improved.
- a major material disadvantage of wood namely swelling and shrinking, largely compensated.
- a change in length due to humidity or temperature changes essentially only takes place in the wood fiber direction. Now run at different layers of wood the grain is different and these layers of wood attached to each other, e.g. by gluing, so a shrinking or swelling of the Wooden building element strongly inhibited.
- a major disadvantage of wood as a material leads to the formation of gaps between the individual blocks, particularly in log houses, is fixed.
- the grain of wood in the layers of wood that follow one another can differ.
- at least two should be different Wood fiber gradients have to reduce the shrinkage characteristics of the wood in to be able to compensate advantageously.
- Advantages of the invention lie in the fact that, on the one hand, the known advantages of wood, such as. good heat and moisture storage capacity, high strength values and high Thermal insulation ability and the negative properties are maintained of wood, such as poor sound insulation ability and high weight, avoided or reduced become.
- the recyclable, naturally renewable, CO 2 -binding, in short, extremely environmentally friendly material wood can be used in a variety of ways in construction and can be used instead of other, less environmentally friendly and more difficult to process 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.
- an increasing number of layers of wood makes a higher one Stability achieved. This makes it possible to process wood that is normal Use for construction purposes are usually not useful. That means it can too extremely weak wood, recycled wood or firewood can be used. Can too According to the invention birch, beech or oak wood and wood that is a marginal product or as excess in the sawmill during production.
- the conventional one could also be regarded as independently inventive Wooden component with the largely biological filler at least partially to fill in.
- types of urea resin for gluing the wood layers, for example, types of urea resin, types of resorcinol resin, Melamine resin types of glue or polyurethane glue are used, whereby the latter are preferred.
- the individual elements that make up the layers of wood are made from fresh, green wood or cut from pre-dried raw material.
- These blanks are according to the invention with structures such as a variety of longitudinal or transverse grooves or crevices.
- Structure is generally understood to mean a plurality of indentations that are in the blanks e.g. by sawing or milling.
- the structure is preferably elongated and straightforward. If necessary, however, it can also be curved or branched his.
- the grooving can e.g. have rectangular, trapezoidal, round or oval grooves.
- the structure of the cuts combine deformations 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 saves a lot of weight compared to solid wood achieved without significantly reducing the stability of the wooden board.
- the weight saving is, for example, about 30%.
- By saving weight it is possible to structured blanks to pack more densely and on spaces or cavities between the blanks.
- a higher stability compared to approximately the same weight savings Solid wood is achieved.
- the structuring of the wood e.g. in the form of a variety of longitudinal or transverse grooves also the advantage of a compared to just a few large spaces better heat and cold insulation, because the mobility of the enclosed gases or the trapped air is significantly reduced.
- the variety the different chambers that result from the structuring an effective Sound propagation prevented.
- a wooden component designed according to the invention is particularly advantageous has at least four, preferably five layers or more.
- Such a wooden building element has tongue and groove-like configurations laterally and / or upwards and downwards.

- the groove-like or tongue-like formations are consecutive in the network Wooden components relative to the direction of formation of the layers or scoring are provided on different or opposite sides.
- the grooves or the structures can also in one of the vertical to the Layer or board surface deviating direction in the wooden layers. Two such, adjacent surfaces of two successive layers thus result in a herringbone pattern in cross section, which has the advantage that by the The grooves are oriented at an angle to the surface and these are laid deeper can. As a result, more material can be obtained from the individual layers of wood relative to the surface be removed. This increases the thermal insulation value considerably and the structures in successive layers can be more successive when connecting Insulate wood layers better from each other.
- groove designs can be partially recessed to be integral To create voids in the construction of a part of a 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 in a casual manner when sawing out or milling out the structures.
- This Surface roughness results in connection with the foam-like filler that Wood component or the structures according to the invention at least partially fills one greatly increased contact area between the filler and the wood. Because this filler advantageously connecting, i.e. contains glue-like components, this leads to a significant improved stability of the wooden component compared to the prior art, because there only smooth blanks are glued.
- the filler also significantly increases the sound absorption properties and the insulation properties of the wooden component.
- Large cavities have the property of cold bridges to build.
- the structuring makes it possible to keep the cavities as small as possible to keep and thus cancel their nearing cold bridge property and still the Advantages of the cavities, namely a lower weight of the wooden component, material savings and maintain the insulation properties of the air.
- a foam-glue mixture or possibly a filling mixture is preferred as the filler is as biological as possible.
- a glue containing or made of lignin exists.
- the more layers of wood are combined to form a wooden component according to the invention the more advantageous properties such as stability and insulation properties are reinforced and soundproofing.
- the stability is ensured by a variety closely adjacent and superimposed blanks with different wood fiber direction achieved.
