Definitions
- the invention relates to wooden components made of glued together Thin-layer layers, for example made of veneer sheets.
- wood construction technology laminated bodies are made of glued together Wooden moldings or wooden panels are widely used and are often used instead of Solid wood parts used. Such wooden components can be found, for example, in door, window, Wall and half-timber construction use, whereby they as slab, frame or block-shaped wooden elements are used.
- Wooden components sometimes have high requirements for the so-called Stamina ", which means, among other things, low crack formation, freedom from distortion and dimensional stability, especially in changing climatic conditions.
- Stamina wooden components
- wooden components - both made of solid and laminated wood - are usually made either by finger jointing (mortise and tenon) or by means of Dowels in the corners of the frame are connected to each other
- finger jointing memory and tenon
- Dowels in the corners of the frame are connected to each other
- the production of such a connection is complex and only lasts to a limited extent after the wood has completely dried out, after painting it often leads to the formation of cracks at the joints.
- EP 320 803 for example, is now a cost-effective, cuboidal wooden body known for working out wooden components from a large number of stacked and glued wood fiber boards exists, and its resilience is equal to that of hardwoods.
- cut plywood strips are known, apart from the wood properties, they have the same disadvantages as solid wood hides.
- cutting out the component in one piece from one Plywood board, especially with frame-shaped components, because of it amount of waste generated is uneconomical.
- Veneer strips can also be used to reinforce the edges.
- plywood panels or whole Blocks of veneer layers glued together from which perpendicular (or - to Achievement of wider grain - diagonally) to the layers, of which however parallel to the wood grain, thin layers of veneer are peeled off, which are then e.g. how Spruce or fir veneer look, but can be made of cheap poplar wood.
- the invention has now set itself the task of using new wooden components to provide great stamina, with different Starting materials can be produced, can be processed in many ways and can also be easily used if required additional materials can be combined.
- Wooden components with surprisingly high strength are now provided for the first time by the present invention in that a multiplicity of thin-layer layers are glued in stacks one above the other, at least every second layer being formed as a frame made of strip-shaped layer sheets, and the joint between adjacent strip-shaped layer sheets of one layer each by one Layer sheet of the subsequent layer is overlapped.
- a multiplicity of thin-layer layers are glued in stacks one above the other, at least every second layer being formed as a frame made of strip-shaped layer sheets, and the joint between adjacent strip-shaped layer sheets of one layer each by one Layer sheet of the subsequent layer is overlapped.
- under stack under stack "understood a package of several (ie 5 or more) layers.
- the layers are layered one above the other in such a way that the outer edge surrounding each layer is aligned with the outer edges of at least one, preferably both, adjacent layer (s).
- Such wooden components have a particular strength and rigidity, especially at their corners, which in addition to the number of layers through the overlapping gluing is involved, thereby the desired maximum possible Strength is achieved.
- the wooden components thus have an excellent Stamina ", which increases with the number of layers and completely avoids cracking. Because of the multiple gluing according to the invention, a considerably higher strength can be achieved than that which is inherent in even high-quality woods, such as solid or tropical woods, or is known from glued wooden strips.
- components according to the invention are also as a frame, for example for doors and windows, executable, which then consist exclusively of frame-shaped layers that cross one another are glued.
- Another advantage of the invention is, among other things, that from cheap, inferior, unsuitable starting materials for timber construction, high quality and compared to solid wood, more stable components can be produced that also with the desired visual appearance and the Physical properties can. In particular, they cannot in the normal furniture industry usable and therefore cheap, narrow (sometimes waste) veneer strips for the Production of both frame-shaped and full-surface layers find, with the usual processing methods for solid wood such as Impregnation, dyeing or pickling can be carried out.
- the layered structure of the wooden component and the free Spaces inside the frame-shaped layers integrate the most diverse Materials such as other types of wood, plastics, metals, cork, etc., in the Wooden component too.
- thin layers are also other materials such as pressed or plywood, cardboard, cardboard, paper, Cork, metals or plastics, especially hard plastic films, for use suitable in wooden components according to the invention.
- materials can be combined within a wooden component.
- inside and different thin-film materials are used outside. So put one prefers the weather or aggressive environmental conditions exposed layers of the wooden component accordingly, if necessary also chemically, resistant or additionally treated, for example impregnated Layer materials.
- For the layers on the room side if necessary optically appealing, possibly differently grained layer materials resp. Veneers, also placed inlaid together, used.
- the core of the Layers of wooden components can be made from cheaper or inferior ones Materials are made.
- the layer sheets can be within a layer and / or differ in different layers with regard to the strip width, the Layer sheet thickness and the structure, for example grain.
- frame-shaped layers of frames with layers of material embedded in them be filled differently from the material of the frame.
- filling are suitable depending on the purpose of the wooden component, in particular: heat-insulating, sound absorbing, bulletproof as well as fire and water resistant materials known type.
- certain woods, such as oak provide sufficient Fire retardant effect for common requirements.
- the frame-filling materials can be fixed with the frame-shaped layers and / or their adjacent layers connected, in particular glued, or only loosely inserted into the frame. A loose connection is advantageous if a - in certain areas - free Stretching and swinging the embedded material within the wooden component is desired.
- one of the final layers in the Distinguish material from the layers in the core of the wooden component is one of the final layers in the Distinguish material from the layers in the core of the wooden component.
- the outermost layer of plastic, aluminum or plywood and the layers in the core of the wooden component be made of plywood.
- the individual layer sheets or strip-shaped sheets are at least within a layer of uniform thickness.
- the individual layers can for example, in dimensions known per se, in particular of about 1, 1.4, 2, 2.5, 3 mm up to 6 mm thick layers can be applied, depending on the desired optical and the desired strength effect.
- a Wooden component with a thickness of 60 mm consist of more than 50 layers.
- Veneers with a thickness of 8 mm or more are not preferred. The thinner the Layers, the more stable and crack-resistant the bond.
- the grain of the layer sheets can be in the glued block run uniformly or alternate between layers; either from location to location Layer, or between parcels of several parallel layers.
- the wooden components according to the invention can be produced in a conventional manner Automated way without great hassle on wood processing plants.
- connection Strength Since you can high through the described new form of connection Strength is achieved, it is also for the production of plywood panels, or beams and strips, for example in timber frame construction, can be used. For example, individual layers of strip-shaped layers arranged in parallel can be used Glue the layer sheets crosswise together to form a block, whereby the butt joint of two layer strips in a position of at least one Layer strips of the next layer is covered.
- frame-shaped layers alternating with the cross-section of the wooden component covering layers, in particular made of wood veneer follow.
- On Change of position can be done for example after each position, so that each Location is the same as the location after the next, or after a series of frame-shaped layers can be interposed between a full-surface layer his.
- the specific weight is of the wooden component individually adjustable without loss of strength.
- the embodiments of wooden components according to the invention include for example doors. These can be made of plastic, aluminum or wood veneer Plywood top layers, and a core of wood veneer layers. In certain embodiments change a frame-shaped core Veneer layer with a full-surface veneer layer. The additional embedding of the cork layers filling the frame in one or more frame-shaped layers, equips such doors with additional insulation and soundproofing properties, which is why the cores of such wooden components naturally also as Wall components are suitable. Of course, instead of cork other known sound absorbing materials, for example so-called Heavy foils, can be used. Doors or wall elements made according to the invention Wooden components can also be reinforced by simple measures to be bulletproof become.
- Doors made from wooden components according to the invention can be used in one usual door stand of approx. 60 mm from, for example, 10 to 30 layer layers be put together.
- the wooden component according to the invention is by no means rectangular mutually extending side surfaces for square or rectangular wooden elements limited.
- the corner connections of the frame-shaped layers are in fact suitable to form any acute or obtuse angle between the oblique glued frame strips running towards each other. Accordingly, according to this Invention wooden components can be made with any number of corners.
- Components according to the invention can also be completely replaced by the absence of full-surface layers can be shaped as a frame and, for example, as a door or Find window frames.
- the strip-shaped layer sheets are then preferably the frame-shaped layers already in the frame width of the frame to be manufactured provided.
- step-shaped frame elements producible.
- it can differ broad layer sheets glued together according to the invention and with a - if necessary, divided - stamps are pressed step-by-step.
- you can mill the steps from the glued block or with a cutting tool peeling.
- FIG. 1 of a frame Wooden component consists of 30 layers of strip-shaped layer sheets, which are together are glued crosswise. In every position, the adjacent layered sheets lie across to each other, whereby - described here with the top 2 layers 1 and 2 - in Layer 1 a layer sheet 1a with its front edge on the inside edge 1b ' of the adjacent layer sheet 1b rests in such a way that its end edge 1b ′′ with the Outer edge 1a 'of the layer sheet 1a is aligned.
- Figure 2 shows a side view of a corner connection of a frame-shaped wooden component over the entire frame thickness layers of layer sheets glued together. Again escapes - described for example using layers 3 and 4 - in layer 3 the front edge 3a '' with the outer edge 3b 'of the adjacent layer sheet. Through the crosswise gluing in the next layer 4 the joints 5 and 5 ' between the sheets of the subsequent layers covered by the layer sheet 4a.
- FIG. 3 shows a cross section through a step-shaped frame 6 trained wooden component, which consists of, stacked, differently wide layer strips was pressed with a split punch 7, 7 ', 7' '. Cracks are through the Layer gluing completely prevented.
- Figure 4 shows in cross section two arbitrarily selected layers of a full area Execution of the wooden component according to the invention, in each case between two frame-shaped veneer layers a full-surface veneer layer is provided.
- the frame of the layer 8 is made of strip-shaped layer sheets 8a, 8b, 8c composed, as described with reference to Figure 1, butt to each other come that the outer edges of the layer sheets in a common, align the outer frame edge.
