Description

The invention relates to a scantling that has at least two top layers made of solid wood having.

Such a scantling is known and is used in the field of wood components especially for the production of window frames and casements, house doors, Balcony doors, conservatory components and other components used. at the known scantlings provide that the two top layers and two The intermediate layers arranged between the top layers consist of solid wood and are glued together. In the known scantlings is disadvantageous  and given the danger that they - especially in the case of larger buildings elements such as front doors, balcony doors, but also large window elements ten or winter garden components - due to the thermal load and / or warped by weather influences and therefore not the original function more fully.

It is therefore provided in the known scantlings that in the interior between between the intermediate layers, additional aluminum sheets or profiles to increase of stability. Such a procedure has the Disadvantage that the aforementioned reinforcing elements in the further Bear processing of the scantlings lead to considerable problems, since these scantlings are now in disadvantageously no longer with normal woodworking tools can be edited. In addition, such scantlings occur regularly also disadvantages in their production.

It is therefore an object of the present invention, a scantling of the ge mentioned type in such a way that with appropriate stability easy editing is given.

This object is achieved in that between the Deckla gene at least one stabilizing core element made of at least one wood material or from at least one bamboo or bamboo-like material is arranged.

The measures according to the invention advantageously result in egg ne scantling created, which is characterized by a high stability and a ge has better swelling and shrinkage behavior than solid wood. There with the scantling according to the invention generally no stabilizing metal sheets or profiles are used, the scantling according to the invention has the advantage that they are using conventional tools, especially conventional wood editing tools, is editable.  

Another advantage of the measures according to the invention is that the invention modern scantlings are characterized by an improved moisture barrier distinguish action.

An advantageous development of the invention provides that the stabilizing Core of the scantling according to the invention made of a composite panel, in particular one multiply glued plywood veneer board or a multiplex board, trained det. Such a measure has the advantage that it makes a kernel ment for the scantling according to the invention is created, which of these is high Gives stability.

Another advantageous development of the invention provides that the veneer gene of the multi-glued composite board essentially orthogonal to the Cover layers of the scantling according to the invention is arranged. Such a measure acquisition has the advantage that a scarf according to the invention constructed in this way has a particularly high stability.

Another advantageous development of the invention provides that that from the Composite plate constructed stabilizing core element in such a way in the Invention According Kantel is arranged that the layers of the composite panel in the essential Chen are arranged parallel to the top layers. Such a measure sits the advantage that it is possible through the measures according to the invention, also use core elements with thin inner cross sections. Moreover is the production technology manufacturing process of the invention Kantel simplified and a higher shut-off effect achieved.

Another advantageous development of the invention provides that the stabilization rende core of the inventive kantet made of a wood fiber material forms is. Such a measure has the advantage that with such  Wood fiber materials at the same time have a higher thermal insulation value and therefore one higher thermal insulation is achieved.

Another advantageous development of the invention provides that the or at least one of the stabilizing core elements of the invention Is made of a chipboard material. Such a measure has the advantage that such chipboard materials as raw material for the ker element is available on the market in various dimensions, which means that Manufacturing costs for the scantling can be reduced.

Another advantageous development of the invention provides that the or at least one of the core elements of the scantling according to the invention from one Bamboo material or a bamboo-like material is formed. The Use of bamboo has the advantage that this material has similar properties Features such as wood-based materials, and also with woodworking processing tools can be easily edited. Through the stabilizing behavior and the high tensile forces of the invention made of a bamboo material or core element made from a bamboo-like material with also avoided in an advantageous manner that the fiction moderate can easily warp. Another advantage is the simple Producibility, since a bamboo braid is used as the bamboo material can, which can be easily tailored to the dimensions of the cantilever.

Another advantageous development of the invention provides that the inventions inventive scantling at least two spaced apart has stabilizing core elements, and that in the stabilizing of the two core elements delimit an insulating or insulating material brought. A scantling constructed in this way has the advantage that it additionally Lich to a high stability also over good insulating and / or isolating egg properties.  

Further advantageous developments of the invention are the subject of Dependent claims.

Further details and advantages of the invention are the exemplary embodiments can be seen, which are described below with reference to the figures. It demonstrate:

Fig. 1 is a perspective view of a first embodiment of a Kantel,

Fig. 2 shows a section through the embodiment of FIG. 1 along the line II-II of Fig. 1,

Fig. 3 shows a second embodiment of a Kantel,

Fig. 4 shows a third embodiment of a Kantel,

Fig. 5 shows a fourth embodiment of a Kantel,

Fig. 6 shows a fifth embodiment of a Kantel,

Fig. 7 shows a sixth embodiment of a Kantel,

Fig. 8 shows a seventh embodiment of an Kantel,

Fig. 9 shows an eighth embodiment of a scantling, and

Fig. 10 shows a ninth embodiment of a scantling.

In Figs. 1 and 2, an embodiment is now generally illustrated with a 1 be recorded Kantel which two outer layers 2 a, 2 b sitting be made of solid wood. Between these two cover layers 2 a, 2 b, a stabilizing core element 10 , in particular a core layer or core layer, made of a wood material is arranged. On the two sides 10 a, 10 b of the stabilizing core element 10 of the jacket 1 , edge elements 3 a, 3 b of a middle layer 3 of the jacket 1 made of solid wood are connected. Composite panels, in particular multiply glued plywood veneer panels, in this case in particular multiplex panels, wood fiber materials such as wood fiber panels, in particular hard or extra-hard wood fiber panels or medium-density wood fiber panels, optionally also wood fiber insulation panels, wood chipboard materials such as press panels or chip moldings, or also layered timber such as blockboard can be used as the wood material be used. It is also possible to use as a stabilizing core element 10 a bamboo or bamboo-like material which has similar properties to wood-based materials. It is also possible that the stabilizing core element 10 of the jacket 1 is formed from a combination of the above groups of materials.

The formation of the stabilizing core 10 made of wood-based materials has the advantage that, due to the blocked construction and the multiple lending of these wood-based materials, an improved swelling and shrinking behavior is given compared to solid wood, so that overall a significantly improved stability compared to a conventional scantling, in which not only were the two deck layers 2 a, 2 b, but also the intermediate layers 3 formed from solid wood between the two cover layers 2 a, 2 b are given.

The described scantling 1 is thus essentially made entirely of solid wood (top layers 2 a, 2 b, middle layer 3 ) or of a wood material (stabilizing core 10 ), so that - since the scantling 1 described, preferably no stabilizing metal sheets or profits are used - this can be machined with conventional tools, in particular with conventional woodworking tools.

In the case shown here, the stabilizing core element 10 is formed from a composite plate, in particular from a blocked and multiply glued plywood veneer panel, which has a large number of veneer layers 11 .

The arrangement of veneer sheets 11 of the formed from multiple laminated plywood veneer stabilizing core member 10 is substantially or, orthogonal to the outer layers 2 a, 2 b has the advantage that hereby a particular DERS high stability of the stabilizing core member 10 is provided, since the individual Veneer layers 11 have a particularly high supporting and thus counteracting deformation of the described jacket 1 .

Since - as already described - the stabilizing core element 10 arranged between the cover layers 2 a, 2 b on both sides 10 a, 10 b of an edge element 3 a, 3 b of the middle layer 3 arranged between the cover layers 2 a, 2 b Kantel 1 is enclosed so that the stabilizing core 10 is invisible from the outside, the Kantel 1 therefore does not differ optically from a conventional Kantet and can therefore be used in an advantageous manner as universally as this.

In Fig. 3, a second embodiment of a scantling 1 is now shown, where provided with the same parts with the same reference numerals and will no longer be described in more detail. The difference between these two scantlings is that the stabilizing core element 10 is surrounded by two edge elements 3 a, 3 b and 4 a, 4 b by two layers 3 , 4 arranged between the cover layers 2 a, 2 b.

In FIG. 4 a third embodiment of a Kantel 1, there is shown, again - provided the same components with the same reference numerals and will not be described in more detail - and also in the subsequent embodiments. The difference between the scantlings 1 shown in FIG. 4 and the scantlings of FIGS. 1-3 is that the stabilizing core element 10 is no longer enclosed by two edge elements 3 a, 3 b of the middle layer 3 , but only one edge element 3 b of the middle layer 3 is provided and the stabilizing core element 10 extends from the edge element 3 b to the opposite side 1 a of the jacket 1 . Such measures me has the advantage that hereby a particularly large stabilizing Ker nElement 10 between the two cover layers 2 a, 2 b is introduced, resulting in an advantageous manner to a high stability. Such a scantling is particularly advantageous if not both sides 1 a, 1 b of the scantling are visibly arranged in the assembled state.

In Fig. 5, a fourth embodiment of a scantling 1 is now shown, which speaks ent essentially the third embodiment shown in Fig. 4 ent. The difference between the exemplary embodiments of FIGS. 4 and 5 can now be seen in the fact that in FIG. 4 the veneer layers 11 of the wood material forming the stabilizing core element 10 are arranged essentially orthogonally to the cover layers 2 a, 2 b, while in fourth execution example of Fig. 5 now these veneer sheets 11 is substantially parallel to the cover layers 2 a, 2 b are arranged.

In FIG. 6, a fifth embodiment of a Kantel 1, there is shown, wel ches differs from the previously described scantlings 1 that the stabilizing core element 10 extends from one side 1a to gegenüberlie constricting side 1b of the Kantel 1, so that the The central position of the jacket 1 is essentially formed by the stabilizing core element 10 . In this case, it is preferred that the individual veneer layers 11 of the wood material forming the stabilizing core element 10 run essentially parallel to the cover layers 2 a, 2 b, although it is also entirely possible that the wood material can also be arranged in this way that his veneer 11 was substantially orthogonal to the top layers 2 a, 2 b.

In Fig. 7, a sixth embodiment of a jacket 1 is shown, which differs from the previous embodiments in that here two stabilizing core elements 10 are arranged between the cover layers 2 a, 2 b, one of the edge elements 3 a, 3 b Middle layer 3 are closed. Between the two stabilizing core elements 10 a, 10 b, a cavity 12 is formed, which serves to receive an insulating and / or insulating material. Such a construction is not only characterized by good stabilizing properties. Rather, one of the like scantlings 1 also has at least improved insulating and / or insulating properties. It is also possible, in the cavity 12, a central member 3 c of the center position employ 3, which can then ge from a lower-timber are made as the two visible and environmental influences unterworfe NEN edge elements 3 a, 3 b of the middle layer. 3

In Fig. 8, a seventh embodiment of a jacket 1 is shown, which differs from the previously shown embodiments in that the middle layer 3 has four edge elements 3 a, 3 b and 3 c, 3 d. Such a construction is characterized by a high stability in the edge region of the jacket 1 . Here, it is preferred that the veneer layers 11 of the stabilizing core 10 forming the wood material to the cover layers 2 a parallel, 2 b angeord net are, but wherein again an orthogonal arrangement of the Fur nierlagen 11 to the outer layers 2 a, 2 b is possible ,

In Fig. 9, an eighth embodiment of a jacket 1 is shown, which differs from the above-described embodiments in that the stabilizing core element 10 is not arranged directly between the cover layers 2 a, 2 b, but that between the stabilizing core element 10 and the top layers 2 a, 2 b further middle layers 5 , 6 is arranged. In FIG. 9, the stabilizing core element 10 is delimited on its side 10 b by an edge element 3 b of a middle layer 3 and extends on its opposite side to the edge 1 a of the jacket 1 . But it is also possible that a further edge element 3 a is provided here, or that the edge element 3 b is omitted, so that the stabilizing core element 10 extends from one side 1 a to the other side 1 b of the jacket 1 .

In the above description, it was assumed that the stabilizing core element or elements 10 is ausgebil det from a plywood veneer panel. However, it is also possible - as already mentioned at the beginning - to form other wood-based materials such as wood-chipboard materials or a bamboo or bamboo-like material which has wood-material-like properties instead of or in addition or in combination.

The Fig. 10 now shows a ninth embodiment of a Kantel 1, the two outer layers 2 a, 2 b, and a middle layer 2 c comprises solid wood. Between the upper face sheet 2a and the middle layer 2 c and the middle layer 2 c and the un direct topsheet 2, a core element is b disposed respectively 10, which is made of a bamboo braid, thus from a bamboo material. The stabilizing behavior and the high tensile forces of bamboo also hereby achieve that the core 1 is stabilized by the core elements 10 in such a way that warping of the edge 1 is prevented. The use of a bamboo wicker also has the advantage that it can be cut to the edge dimensions in a particularly simple manner.

It is also not necessary that the stabilizing core element 10 or - if there is more than one stabilizing core element 10 per scantling 1 - all stabilizing core elements 10 are made of the same material. It is also possible NaEM Lich, a stabilizing core member 10 fen of several Werkstof or more existing in a Kantel 1 Kernele stabilizing elements 10, the individual core stabilizing elements 10 each composed of materials difference handy form.

In summary, it should be noted that the measures described create a scantling 1 which is characterized by high stability and simple processing.
