Description

The invention relates to a wooden component that is visible Use for wooden structures, especially for windows or Door profiles, wooden beams, furniture, etc. is usable. The The invention further relates to a window or door jacket Window or door profile and a manufacturing process therefor.

Wooden components are known from the known prior art, which have a very thin layer of veneer. such Wooden components have the advantage that the carrier material can be inexpensive and only the veneer is high quality wood. Before the veneer on the Carrier material is applied, the carrier material is too to edit. Machining of the wooden component including veneer is therefore not possible because the veneer will be damaged. Known wooden components have the disadvantage that the Backing material without processing the veneer, and only in a final step when the backing material is its provided geometry, the veneer on the Carrier material is applied.

DE 200 11 080 U1 describes a scantling with at least two Solid wood top layers became known.

EP 0 445 663 A1 describes a glued wood profile Production of, for example, window elements become that of several glued together, in Cross-section rectangular, made of solid wood There are wooden slats.

Window / door frames are known from DE 299 00 623 U1 become from multi-layer profile elements Contain glazing. At least there is a wooden strip on one side of the profile elements intended.

The known wooden components have the disadvantage that the Wood consumption of high quality, visible when installed Wood is very high.

The present invention is therefore based on the object a wooden component, in particular a window or door jacket or window or door profile, and a method for Manufacture of wooden components or window or Door scantlings provide the optimal properties has, which may look optically high quality, but still is inexpensive and its production with little Workload is connected. In particular, it should also machining on site without the wooden component unusable will be possible.

This object is achieved with a wooden component according to claim 1 solved. The wooden component according to the invention has the advantage that it as a wooden component to be processed or installed is available. The side of the wooden component that after whose processing or after its installation is visible, has the visible wood. The visible wood has such a strength that it is cutting depending on the intended use is editable. This has the advantage that on the later, i.e. after processing and assembling the wooden component, visible surface sections of the wooden component only the visible wood is visible. On this Sections thus comes to the core despite machining Editing not revealed; the sight wood is also after its processing as a uniform surface for the Viewer visible. This gives the impression that the wooden component is made of solid wood, as it is the visible wood. Damage to the wooden component, such that it becomes unusable is due to the provided thickness of the visible wood is not possible. In places which are not visible after assembly of the wooden component it is harmless if the wood core due to machining of the wooden component comes to light. These places affect the uniform visual perception of the Not a wooden component.

It is envisaged that the special environmental conditions facing sides of the wooden component the environmental conditions fair wood. For example, is a Exposed side of the wooden component to weather, so it can Sight wood formed on this side of the wooden component be that it does justice to these weather conditions. The core can be made of wood that is not in itself appropriate environmental conditions. By providing the Sight wood on the core shields the sight wood from the core the environmental conditions.

As a very suitable and permanently durable exposed wood Rift wood and / or thermally refined wood has proven itself.

It is particularly advantageous if the exposed timbers are made of Riftsichtholz are and that the opposite long sides of two facing wood from the two other exposed timbers are covered, the strength of these approx. the distance between the annual rings corresponds to the visible timbers, the long sides of which are covered. The interface between the exposed wood is as good as not visible. In addition, for example, none Moisture penetrate the wood and damage it.

The core is preferably a wooden core. The core can but also made of plastic, such as PU, Syrodur or a similar high insulation material.

It is particularly advantageous if the untreated exposed wood a thickness between 1 mm and 50 mm, in particular between 3 mm and 15 mm. Through such strengths ensures that machining of the Wooden component is possible without revealing the core comes. The ratio of core to starch thickness is preferably greater than 2: 1, 5: 1 or 12: 1. By providing Such a relationship ensures that before all the core absorbs forces acting on the wooden component.

In a preferred embodiment of the invention, the Core has a largely rectangular cross-section, the Sighted wood on all long sides of the wooden component is provided. Such wooden components are particularly suitable advantageous for processing or for installation in Wooden structures. The wooden components can for example in Trade as components in standard sizes and how Previous solid wood components, handled from a single piece of wood and processed. Because of the relatively strong Sight wood can warp or tear open Wood component or the core are counteracted. in the Compared to solid wood components are those according to the invention Wooden components are more dimensionally stable.

The core can consist of poor quality and / or be optically unsightly wood, especially made of lumber, Squared timber, glulam or the like .. It is advantageous if the The core is designed so that it fits onto the wooden component acting external forces.

In contrast to the core, the visible wood can be of high quality high quality and / or visually beautiful wood.

Those acting on the wooden component advantageously act external forces not on the visible wood. Depending on Purpose of the wooden component can be various Find sight wood.

Rift wood and / or has proven to be a very durable exposed wood thermally refined wood has proven itself. Rift wood or thermal refined wood is particularly weather-resistant. Riftholz is such wood, whose annual rings are perpendicular to that of the Side exposed to weather. Thermally refined Wood is wood that undergoes thermal treatment exposed above 100 ° C in particular. By such Treatment changes the physical properties of the Wood, for example for setting (dismantling) in the wood existing voltages. Furthermore, the thermal treatment of microbes, bacteria in the wood, Viruses, fungi, etc. are killed, leaving the wood against weather and is more resistant to environmental pollution. The thermal Treatment can range from approximately 100 ° C to 300 ° C without that the wood burns take place. Especially at Temperatures above 150 ° C change the chemical and physical properties of the cell walls of the wood, which makes the wood more resistant.

Wooden components according to the invention can also be constructed in this way be that the core is multiple, joined core parts includes. The core parts are joined in particular cohesive, preferably by gluing instead.

The inseparable connection of the wooden component with the visible wood is also advantageously cohesive, especially by gluing.

For high-quality wooden components made from single varieties Obtaining materials is in particular according to the invention provided that the wooden component and the exposed wood each corresponding solid wood.

The above-mentioned task is further through window or Door scantlings for the production of window or door profiles solved, which have a wooden component according to the invention or consist of wooden components according to the invention. such Window or door scantlings have the decisive advantage that they can be used to machine any window or Door profiles can be used. Depending on the type of Profiles, the thickness of the visible wood is to be provided. Window or door scantlings according to the invention are inexpensive manufacture. The expensive, weatherproof wood, Rift wood in particular, can be very economical as sight wood Find use. In contrast, the core can consist of one relatively inexpensive wood. Nevertheless, it is window or door profiles produced in this way Solid wood window profiles.

Such window or door scantlings are advantageously like this trained that at least the weather area facing side of the scantling a thermally refined visible wood and / or has a sifted timber.

It is also advantageous if the one facing the inner region On the side of the scantling a visually beautiful sight wood, for example a knot-free exposed wood.

The above task is also through window or Door profiles solved, the window or according to the invention Door scantlings are made. Such window or Door profiles are solid wood profiles that are much cheaper can be manufactured as window or door profiles that consist entirely of the wood type of the visible wood.

Furthermore, the stated object is achieved by a method for the production of wooden components according to the invention and / or Window or door scantlings according to the invention, wherein in one first working step at least two cores with one Sight wood are glued and in a second step the two cores by cutting through the visible wood be separated from each other so that two wooden components arise. Such a method has the advantage that Wooden components or scantlings according to the invention in a simple manner and ways are available. First three Basic wooden bodies, namely two cores and one sight wood, two part-finished wooden components are manufactured. The fat The visible timber to be provided depends on the one to be provided Thickness of the visible wood of the resulting wooden components. The Visible wood to be used preferably has a thickness, the two strengths to be provided plus the cut allowance equivalent.

The method according to the invention can be developed in this way be that in a third step another Glued wood with still free sides of the two cores glued and that in a fourth step the cores through a cut through the sight wood separated again so that again two part-finished wooden components arise. Consequently, steps 1 and 2 become resulting wooden components by gluing another Visible wood again provided two wooden components. The fat the visible wood to be used depends on the thickness of the visible wood, how it should be processed.

Steps 3 and 4 can advantageously be repeated repeated, if necessary as often, until All sides of the cores have exposed wood.

A particularly advantageous method results when the exposed wood is thermally bonded to the core is refined. Accordingly, there is an advantageous one Procedure when the sight wood is in rift position with the respective Cores is glued.

Further advantageous refinements and details of Invention can be found in the following description in which the invention with reference to that shown in the drawing Exemplary embodiments are described and explained in more detail.

Different steps for the production of a wooden component according to the invention.

1 is processed as a window profile 10 Window scantling 12 shown. The window scantling 12 is out a solid wooden component. One narrow side 14 of the Window scantling 12 adjoins masonry 16. The other Narrow side 18 has a longitudinal groove 20 for receiving of sealant 22 and a glass sheet 24 is provided is.

Those facing the outside 26 and the inside 28 Long sides 30 and 32 are selected so that the annual rings 34 the window frame 12 perpendicular to the long sides 30 and 32 run. The side of the wood that is perpendicular to the Annual rings 34 runs, is the so-called reef side. she has the advantage that it is weatherproof. Moisture is difficult to penetrate into the wood especially if the wood is late wood is.

Such known window scantlings 12 are made externally produces beautiful and healthy trees, with wooden sections being the errors that occur to the outside must be cut out. This leads to a very low yield of the log, because the larger the cross-section of the window frame, the smaller the likelihood is a flawless and therefore to get a suitable piece of wood.

2 is also known, so-called To provide three-layer scantlings 42. The two outer layers 44 and 46 are designed as rift wood. The middle layer 48, which has a thickness corresponding to the longitudinal groove 20, is, for example, partially galvanized wood, which is not must be error-free.

The use of a three-layer crest 42 increases the Yield compared to a window scantling 12 according to FIG. 1.

Overall, the yield is still relatively low because of the middle layer 48 the width of the glass pane 24 or Has longitudinal groove 20. Another disadvantage is that the Glass pane 24 facing narrow sides of the two outer Layers 44 and 46 are weather sensitive.

The shown in Fig. 3, to an inventive Window profile 50 processed window scantling according to the invention 52 has on its narrow sides 14 and 18 and on their Long sides 30 and 32 lamellar exposed timbers 54, 56, 58 and 60 on. The visible timbers 54, 56, 58, 60 are around a core, 62, which is designed as a wooden core, glued. The wood core 62 can be made from cheap partially zinc-coated pieces of wood Construction timber, squared timber, glulam, rough sawn timber, Solid construction wood or similar wood. The location of the Annual rings of the wood core 62 are irrelevant.

The visible woods 54, 56, 58 and 60, on the other hand, are qualitative higher quality, especially weather-resistant woods. It is preferably rifle woods, in which the Annual rings 64 perpendicular to the respective outer surface of the Sight wood 54, 56, 58, 60 run. This results in a weather resistance. The exposed timbers 54, 56, 58, 60 can also be made of protective, especially refined wood. One is particularly advantageous thermal finishing. The visible timbers can also vary Desire also have different colors.

Because of the complete covering of the wooden core 62 results according to the invention a window scantling 52, the surface of which made of weather-resistant exposed wood on the one hand and on the other made of selected, visually beautiful looking wood.

The thickness of the exposed timber 54 to 60 should be selected that machining the window scantling 52 to create a suitable window profile 50 is possible. For example the thickness of the visible wood 58 is designed so that the Groove bottom of groove 20 in visible wood 58, and not in wood core 62 lies. However, this does not necessarily have to be the case because the section having the groove 20 is not after assembly is visible. Partial machining of the wood core is in harmless in this area. By providing suitable Sealant between glass pane 24 and sight wood 58 can also no moisture can penetrate into the wooden core 62.

3 has compared to the known Window scantlings 12, 42 have the advantage that overall only very much little high quality wood for the visible wood 54 to 60 is to be used. The main component of the window frame 52 is the wood core 62, which consist of inferior wood can.

By gluing the visible wood 54 to 60 onto the wooden core 62 the delay of the window frame 52 is blocked. Add to that also the strength of the exposed timbers 54 to 60, which normally between 1 mm and 50 mm, especially between 3 mm and 15 mm.

3 is particularly advantageous in the embodiment according to FIG. that the visible timbers 54, 56, 58, 60 are made of rift softwood and that the opposite long sides of the two opposite wooden timbers 58, 60 from the other two Sight wood 54, 56 are covered, the strength of this two timbers 54, 56 approximately the distance of the Corresponding annual rings 64 of the visible woods 58, 60 corresponds. The seams between the exposed wood are so good as not visible. In addition, for example, none Moisture penetrate the wood and damage it.

4, a wooden component 70 according to the invention is in shape a beam for a ceiling construction shown. The Wooden component 70 is in sections in a ceiling 72 edged. All long sides of the wooden component 70 are from lamellar exposed wood 74 surround. The on that Loads acting on the wooden component are carried by the wooden core 76 added. The wood core 76 advantageously consists of an unsightly, inferior wood. The visible wood 74 however, are of higher quality, in particular nice looking wood. A processing of the wooden component 70 when installed with the ceiling 72 is due to the Layered ceilings of the exposed timber 74 possible without the Holzkern 76 comes to light when installed. To the Wooden component 70 can, for example, as dashed in Fig. 4 indicated, a further component 78, for example a Wall segment or the like can be arranged. This can also be done here Wood component 70 can be machined.

Fig. 5 shows a wooden component 80 according to the invention as it is can be commercially available, for example. The external dimensions of the wooden component 80 correspond to known, available dimensions. The visible wood 74 are depending on the requirements of the Wooden component 80 provided with different properties. For example, they can be thermally refined, one Have rift surface, be color-treated and / or made optically beautiful wood. The strength of the visible wood 74 is chosen here so that machining is possible. In particular, the thickness is between 1 mm and 5 mm. The ratio of wood core strength to visible wood strength is advantageously greater than 5: 1 and in particular greater than 12: 1st In this case, the facing timber 74 advantageously each have the same strength.

6.1 to 6.5 show different process steps for the production of a wooden component according to the invention.

6.1 are wooden cores 10 and visible woods 92 ' provide. The visible woods 92 'have a thickness which is twice the size of the one to be manufactured Wooden component plus cutting allowance. The wood cores 90 are with the exposed wood 92 ', which is the same width as that Have wooden cores 90, glued flush. This is shown in Fig. 6.2. In a next step, the visible wood 92 ' in the middle along the dash-dotted lines 82 severed. The separated wooden components are shown in Fig. 6.3 shown.

In a next step, the wooden components are over Rotated 90 ° and are attached to the still free sides of the wooden core 90 glued. The exposed timbers 96 'also extend over the free narrow sides the visible wood 92. Then the Visible wood 96 along the saw lines 98.

Ultimately one gets, as in Fig. 6.5 in cross section shown, wooden components 100 according to the invention Visible woods 92 'and 96' are advantageously like this. chosen that they are rift woods.

The cores described in the figures must be according to the invention are not wooden cores. It can too Plastic cores, such as PU, Syrodur or similar substances are used.

All in the description, the following claims and the Features shown can be drawn individually as well also in any combination with each other be essential to the invention.
