Description


    <Desc / Clms Page number 1>
 



   The invention relates to a component and a method for producing the same in accordance with the preambles of claims 1, 28 and 29 and the use of the component according to claims 26 and 27.



   A component of the generic type is known from US Pat. No. 5,738,924 A, with two cover layers which are arranged at a distance from one another via a core layer and the core layer is formed by a plurality of spacer elements which are arranged distributed over mutually facing cover surfaces of the cover layers and the spacer elements in their Longitudinal extension are spatially deformed. The spacer elements are formed by veneer strips made of wood. Narrow side surfaces of the spacer elements and the inner cover surfaces of the cover layers form mutually facing, parallel connection surfaces, which are butted against one another.

   A connection layer is applied over the entire surface of each of the inner cover surfaces of the two cover layers and the core layer is pressed into the connection layer until the narrow side surfaces of the spacer elements abut one another on the inner cover surfaces. The increased material requirements caused solely by the geometrical shape of the spacer elements and the conditional load-bearing capacity of the component prove to be disadvantageous.

   It is therefore to be expected that this known component can only be subjected to higher loads to a limited extent, since in such an application high stress peaks occur in the spacer elements and in the connection areas between the spacer elements and cover layers due to the unfavorable, geometric shape of the spacer elements which, in order to prevent material breakage, can only be compensated for by higher thicknesses of the cover layers and spacer elements, which, however, entails an increase in the proportion of material.



   A component is known from AT 196 113 B, with two cover layers, which are arranged at a distance from one another via a core layer and the core layer is formed by a plurality of spacer elements arranged distributed over mutually facing cover surfaces of the cover layers, the spacer elements being undulating are formed and run obliquely against the inner cover surface of the cover layers and the adjacent spacer elements which are connected to one another at the points of contact are each directed crosswise towards one another. Flat spacer elements are arranged between the wavy spacer elements. The material-intensive structure of the core layer is disadvantageous and this component cannot be exposed, or only to a very limited extent, to loads acting in the direction perpendicular or oblique to the component level.



   A generic component is also known from AT 198 000 B, which has two cover layers and honeycomb-like cells which are distributed over their inner cover surfaces and which consist of prefabricated flat material, in particular paper. The cohesive cells are connected to the cover layers by a connection layer made of cement-like material, which is attached to the inner cover surface of the cover layers.

   In addition, a method for producing this component is known, in which the cover layers are coated with flame-resistant, cement-like material, whereupon the connected cells are initially placed on the first cover layer and pressed against it, so that the cement-like elements present on the cells and on the cover layer Combine the masses with one another, whereupon the second cover layer on the inner surface is also covered with flame-resistant cement-like material and pressed against the cells, whereupon the composite panel thus obtained hardens.

   The known component is unsuitable for the transmission of payloads, since even with a slight deflection of one of the cover layers the connection layer breaks and the load-bearing connection between the cells and the cover layers is destroyed and its largely manual production is very cost-intensive.



   AT 202 324 B discloses a core layer which is arranged between two cover layers of a component and which consists of a multiplicity of strips of paper or other flexible material which are connected to one another in a row and are spaced apart and a plurality of which are pulled apart forms contiguous honeycomb-like cells.



  This known honeycomb-like core layer is essentially only suitable for self-supporting components and the transmission of payloads is not possible with this known core layer, since the core layer consisting of paper or other flexible material will collapse under these loads.



   A cell-like core layer made of cardboard, impregnated or non-impregnated paper,

  <Desc / Clms Page number 2>

 Metal, plastic, is also known from AT 208 047 B, in which each individual strip is provided with double-Z folds which are contiguously shaped in a meandering manner and are directed against one another, and several strips are layered only with their mutually facing longitudinal parts of the double -Z folding alternately connected to each other, so that a large number of connected, regular, polygonal cells are formed.



  Furthermore, a method for producing the honeycomb-like core layer is known, in which endless strips are formed into a double Z-fold in an uninterrupted work step and, after application of a connecting means, the connected cells thus formed to the mutually facing longitudinal parts of the double-Z-fold honeycomb-like core layer.



  A disadvantage is the weakening of the cross-section of each individual strip, which may bear loads, in the area of the sharp-edged Z-fold, as a result of which this honeycomb-like core layer is unsuitable for the transmission of payloads, and the production of this core layer is difficult.



   DE 925 858 C2 discloses a carrier-shaped component which is equipped with one or more spacer elements which are offset in a wave-like manner from one another by half a wavelength or in phase and extend in parallel in the longitudinal direction of the component and at a distance from it in a direction transverse thereto Non-form-glued plywood made spacer elements, in particular webs, in which recesses recessed in strip-shaped, in particular board-shaped or beam-shaped cover layers engage or with which the spacer elements are connected in a non-positive and positive manner.

   Such spacer elements made of plywood are spaced apart from one another and are preferably connected to the cover layers in a non-positive and positive manner, as a result of which these wooden components have only a low load-bearing capacity in relation to transverse forces acting in the transverse direction. In addition, owing to the small width of the cover layers formed from a square timber cross-section, which is limited by the growth limits, the area of use of these components as a surface element is severely restricted and such components can only be loaded in the middle in order to prevent the risk of tipping to the side.

   Furthermore, these have the disadvantage that the amplitude and lateral opening width of the spacer elements are dimensioned very small and the high restoring forces inherent in the spacer element in the adhesive joints between the cover layer and the spacer element cause high shear forces transverse to the longitudinal extension of the component, which means that the cost-intensive and Production-technically complex gluing of the cover layer with the spacer is absolutely necessary.



   EP 0 568 270 B1 discloses a component with cover layers that are spaced apart from one another by means of spacer elements, the spacer elements of which form a plurality of separate cell-shaped chambers or cavities in the longitudinal extension of the component. The spacer elements, in particular webs, which touch at least in some areas, are connected to the cover layers in the touching partial areas and on their narrow sides. The cellular chambers formed by the webs are filled with a filler and form a core which is arranged between the first and the second cover layer and is connected to the latter.

   Such components made of wood have the disadvantage that the cover layers are supported only over part of their width by the spacer elements, as a result of which they have a low load-bearing capacity, in particular in the edge zones of the narrow side surfaces, in particular in a plane perpendicular to their longitudinal extension. Furthermore, these components, which transmit essentially only very low loads, cannot be used as highly resilient primary support structures, which in turn leads to a very restricted area of use.



   Furthermore, document DE 195 21 027 A1 discloses a component, in particular a double-T support, consisting of two cover layers spaced apart from one another by means of spacers, in particular webs, with only one web running unevenly or undulating in the longitudinal extent of the component between the cover layers is arranged. By joining several components, in particular corrugated webs, a flat element can also be created. Such designs of components made of wood have the disadvantage that the support elements connected in the longitudinal direction to form a surface element are stressed in the area of the joining surfaces when subjected to high shear stress and a gradation can occur between two interconnected cover layers.

   To a large area

  <Desc / Clms Page number 3>

 To create a component, a large number of joining surfaces are therefore required, which can only be produced with a correspondingly high production outlay. Furthermore, the area of application is severely restricted, since several double-T girders have to be strung together to create a flat component, as a result of which the component has only a low bending stiffness in the transverse direction due to the lack of fiber components in the width direction of the component.



   In a further published publication EP 0 314 625 A1 there is a component with two cover layers spaced apart from one another by a spacer element, which have a further layer on their surfaces facing away from one another, one of which supports a decorative plate and the other supports for a rear protective plate is known. The spacer element, in particular the cells of the honeycomb-shaped core layer, is connected to the cover layers, in particular glued to them with a flame-retardant adhesive.



  The main disadvantage is that these components are not load-bearing, which means that they may not be used as a primary support structure. In addition, with this component having a comparatively identical load-bearing capacity to the component according to the invention, a much higher material volume of the core layer of approximately 50% with respect to the material volume of the component is required for constructional reasons and the spacer elements of the core layer can only be produced with extremely high economic outlay.



   All these systems have the disadvantage of the large material requirement with a relatively low load capacity or load-bearing capacity of the component, and its design as a large-area wall, floor or ceiling element is only limited or is possible only with extremely great effort in terms of production , However, these components are not, as is required in today's world, suitable for rapid construction of buildings, where prefabricated components with a length of up to 20 m and a width of up to 4 m are preferred, for example, only on existing foundation supports fastened or directly connected to each other via fastening elements such as screws, nails, etc. and an inexpensive construction is hardly possible.

   As is known, for example, from DE 925 858 C2, the spacer elements are inserted and glued in recesses arranged recessed in the cover layers to enlarge the connecting surfaces between the spacer elements and the cover layers, for which purpose, in order not to reduce the load-bearing capacity, the thickness of the cover layers at least by the depth the recess has to be made larger and the material requirement for the cover layers has to be increased significantly as a result. These wooden components are therefore not producible for spans of up to 20 m and a width of 4 m and are therefore no longer up to the economic requirements on the market.



   A further considerable disadvantage of these shape-glued wooden components is that the use in earthquake-prone areas is only possible to a limited extent, since they can only be designed as large-area components in such a way that they serve as spaced-apart supports, which are made from a large-area flat plate are spanned, but this also means that no force can be transmitted from dynamic forces acting on the plate in the plate itself. In the other case, that several longitudinal components are connected to each other on their longitudinal side surfaces, the cover layers or the belts will fail in the area of the adhesive joints and the assembled flat component will tip or break.



   The present invention has for its object to provide a dimensionally stable and easy to produce component, the material content required for the production should be kept as low as possible. In particular, a thin-walled structural design of the component, which can also be used in areas prone to earthquakes, is to be created.



   The object of the invention is achieved by the features in the characterizing part of claim 1. The advantage lies in the fact that the use of wood-based material for the spacer elements and cover layers and the formation of the spatially deformed, in particular wave-shaped, spacer elements results in a considerable reduction in the proportion of wood required, in contrast to structural elements made of wood, with the same load-bearing capacity and can have its own weight as well as the entire material requirement, even with large spans, can be kept low.



  In addition, the wave-shaped curved spacer elements can also

  <Desc / Clms Page number 4>

 Bulging of the cover layer can be prevented with low thicknesses and load transfer in both the longitudinal and the width direction of the brewing element is essentially possible to the same extent.



   The embodiment according to claim 2 is also advantageous, since the optimum of the required material requirement or the material volume of the core layer is found from spacer elements of the component and the bulging of the cover layers as a result of impact loads can be prevented by the wavy spacer elements. The large-area cover layers spanning the core layer also allow force to be transmitted in the cover layers and force to be transferred to the core layer.



   According to the designs according to claims 3 and 4, already known and well-proven chipboard or fiberboard or coarse chipboard manufactured in large quantities at low manufacturing costs can be used, which contributes to an inexpensive construction of the component. It is also possible to adapt to different types of loads and adapt to different areas of application. In a preferred embodiment, the cover layer has at least two cover layers or cover layer areas running parallel to one another with respect to the orientation of the wood or wood material elements and at least one intermediate layer or an intermediate layer area running transversely thereto, the wood or wood material elements of the Top layers or

   Cover layer areas run in planes oriented largely parallel to the inner cover surface in the longitudinal extent of the cover layer. Also in a preferred embodiment variant of the spacer element, this has, over its thickness, at least two cover layers or cover layer areas running parallel to one another with respect to the orientation of the wood or wood material elements and at least one intermediate layer or intermediate layer area running transversely to these, the wood or Wood-based material elements of the cover layers run in planes oriented largely perpendicular to the narrow side surface in the longitudinal extension of the spacer element.



   The designs according to claims 5 and 6 are also advantageous, since the thin-walled load-bearing construction, above all, facilitates the manufacture of the wave-shaped curved spacer elements by means of corresponding manufacturing processes known from the prior art, such as compression molding, preferably under the influence of temperature etc. becomes possible.



   The further advantageous embodiments according to claims 7 to 9 have the advantage that the connecting and / or solidifying agent which can flow in the initial state passes through the open-pore or diffusion-open connecting surfaces of the cover layer and spacer elements and even larger pores and / or cavities through the Connection surfaces diffusing flowable adhesive are filled and this partially adheres to the wood or wood-based material elements or

   is absorbed by these and, after a predeterminable setting time, the hardened connecting and / or strengthening agent is connected to a multiplicity of wood or wood material elements and forms a connecting and / or strengthening zone which extends beyond the connecting surfaces into the material interior of the spacer element - Tes and the cover layer extends and thus an enlargement of the load-bearing connection cross section is created in a simple manner. The hardened connecting and / or strengthening agent forms a solidification zone within the spacer element and the cover layer and a connection zone or a connection element between the spacer element and the cover layer.

   By creating this connection and / or consolidation zone, high mechanical loads, in particular tensile, compressive, shear, and torsional stresses, can be transmitted even with small cross sections of the spacer elements and cover layers. The connection and / or consolidation zone preferably has a higher mechanical strength than regions of the cover layer and / or spacer elements adjacent to the connection and / or consolidation zone. This is possible insofar as the open-pore structure of the spacer elements and the top layer made of wood-based material distributes or absorbs the flowable adhesive over a part of the area by capillary action, and due to the structure a toothing or

   Chopping effect between the cover layer and the spacer element arises and a considerable increase in the breaking values up to 7 N / mm2 is achieved even by the butt gluing.



   The further developments according to claims 10 and 11 have the advantage that for different static or dynamic load cases, in particular for parallel to the component level

  <Desc / Clms Page number 5>

 Forces acting in the direction can be adapted and the component's elastic behavior or vibration behavior, in particular for use in earthquake areas, can be influenced. By appropriate choice of the connection areas, it is possible in a simple manner to make a partial area of the spacer element lying between two successive connection areas elastically flexible and to optimize its vibration behavior due to a dynamic load.



   The configuration according to claim 12 enables the surface of the at least one cover layer to be used for further uses, such as for example the production of electrical power etc. or a room can be designed.



   The developments according to claims 13 to 16 are also advantageous, as a result of which a load-transferring component which can be modified for different purposes, for example fire resistance or moisture resistance or weather resistance etc., is created.



  It is thus possible in a simple manner to provide the component with a target erosion zone or to design at least one of the cover layers as a target erosion zone, so that the component maintains its load-bearing capacity up to a predetermined erosion resistance period.



  If one of two components arranged one above the other and connected to one another is formed with the target erosion zone, one of the two components can also absorb the loads after a predetermined erosion resistance period. On the other hand, the layer fastened or formed on at least one cover surface of the cover layers facing away from the spacer elements can be made of a wear-resistant and highly stressable material, e.g. B. plastic, or a glued-on water-repellent film are formed, whereby the range of uses of the component is expanded. It is also advantageous to design the cover layer as a vapor barrier, as a result of which the passage of steam is prevented and the functionality of the component is improved.

   On the other hand, this layer can advantageously also be formed from a material which releases water at elevated temperatures. A component optimized in terms of thermal insulation, fire protection, sound absorption, weather resistance can thus be provided.



   According to the other embodiment variants according to claims 17 to 19, standardized materials create a load-transferring component which can be modified for different loads or loads and which, in particular, is resistant to external environmental influences. In addition, the large-area cover layers have proven to be advantageous, since it is now possible to simultaneously absorb high loads with a low component weight and large spans, e.g. B. 6m, 12m, to cover and to increase the load-bearing capacity and torsional rigidity of the component by the formation of multilayer cover layers and / or spacer elements. The functionality of the component can be additionally increased by designing at least one layer of the cover layers as a vapor barrier.



   An embodiment according to claim 20 is also advantageous, in which diffusion-open cover layers can be formed by simply providing passage openings.



   However, the designs according to claims 21 and 22 are also advantageous, since this allows any solid to be produced in a simple manner, the areas of use of which are widely used.



   According to claim 23, an optimized shape is formed against the forces or loads acting in the direction of the side walls, with a high degree of security against lateral bulging, since the spacer elements or webs touch tangentially and support each other. An additional advantage to the supporting effect is an increase in the lateral force transmission of the component in the direction of the width, wherein tilting of the webs can be avoided when the components are installed in an oblique position.



   The development according to claim 24 contributes to a further increase in the load-bearing capacity of the component.



   In the embodiment according to claim 25, a property adapted to different requirements, in particular a reduction in the heat transmission range or attenuation of the noise level etc., can be achieved. In this context, however, the multitude of cavities which are sealed off and are airtight and which are distributed over the top surface of the components is advantageous, in which the preferably flame-retardant and / or non-combustible filler is introduced, because

  <Desc / Clms Page number 6>

 due to this segmentation, even when the component is installed at an angle, none of the desired properties, eg. B. heat insulation, deteriorating settlement phenomena of the filler occur.

   A further advantage is that the filler in the hermetically sealed cavities remains unaffected by external environmental influences, which makes the components highly durable or stable, and the burning resistance of the filler is high, since there is a flow between the individual cavities of air and thereby fire propagation is prevented. Of course, fiber-reinforced plastic can also be added to the filler to increase the load-bearing capacity and shear strength of the component.



   The component according to the invention is used above all as a wall and / or ceiling element etc. for a supporting structure of a building in environments prone to vibration and / or on soft foundation soils, since this has a low mass and high rigidity and thus a high natural vibration frequency, in particular in the event of forces acting in a direction parallel to the component plane. Furthermore, the formation of large-format components, based on a predetermined area, e.g. Top surface, wall surface etc., the number of statically problematic connection points between components can be drastically reduced.

   Due to the differently aligned wood or wood-based material elements in the cover layer and / or in the spacer element, the stress peaks occurring during an earthquake are reduced, especially in corner areas, such as door and window cutouts of a building, so that the component can be used optimally in earthquake areas is.



   It is also advantageous to use the component according to claim 27 as formwork panel, since even with large-format formats, such as a length of 10 m and a width of 3 m, it poses a high load, in particular up to 10 tons, without deforming inadmissibly in the process. can record.



   The object of the invention is also achieved by the measures according to claim 28.



  The advantage here is that a largely fully automated production of the component in an endless process is now possible in a simple manner at low manufacturing costs. The vertical alignment of the spacer elements on the inner cover surface and the butt connection of the spacer elements to the cover layer are particularly advantageous for production.



   Furthermore, the object of the invention is also achieved by the measures according to claim 29. The advantage is that it is possible to react to different batches with different formats quickly and without having to carry out major conversion work, and a high degree of flexibility in production is possible.



   The measure according to claim 30 is also advantageous, as a result of which the throughput time for the production of the component can be considerably reduced.



   According to the measures according to claims 31 to 33, different variants of the production of the component are shown, as a result of which a different sequence of the production process can be carried out and the core layer of spacer elements, which in the extended state forms a latticework, is clocked or continuously the lower cover layer can be put on and connected to it. The measure according to claim 32 is particularly advantageous, as a result of which the connecting and / or strengthening agent can be easily applied to narrow side surfaces of the spacer elements.

   The core layer is expediently placed fully automatically in cycles dependent on the speed and / or depending on the length of the core layer on the inner cover surface in the longitudinal or width direction of the lower cover layer, so that the production can be carried out in large numbers at low manufacturing costs. According to claim 33, the advantage is made possible that preformed spacer elements, for example molded or extruded plate strips made of wood-based material, are placed on the cover layer in the tension-free state and connected to it.



  As a result, the core layer forms an essentially force-free system, so that the stress, in particular shear forces within the adhesive joint, caused by the restoring forces of the spacer elements can be avoided.



   The measure according to claim 34 is also advantageous, whereby on the one hand the structure formed by the pores and cavities and wood-based material elements is made accessible or enlarged in the area of the connecting surfaces of the cover layer and spacer elements, whereby the flow or diffusion of the connecting and / or strengthening agent in the interior of the material

  <Desc / Clms Page number 7>

 the cover layer and spacer elements is improved and on the other hand a flat or full-surface support for the spacer elements is created on the inner cover surface of the cover layer.



   Finally, the measure according to claim 35 is also advantageous, since in the course of the manufacture of the component directly in a subsequent work process, the component already becomes an end product, such as a roof element with supporting elements, e.g. B. roof battens, and / or weather protection can be produced.

   In the introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names.



   The location information selected in the description, such as. B. above, below, laterally, etc. refer to the figure described and illustrated immediately and are to be transferred to the new position in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.



   1 to 4 show a flat, self-supporting, dimensionally stable component 1 according to the invention in different views and in a highly simplified, schematic representation. The component 1, which is at least partially load-bearing and / or self-supporting and torsionally rigid and made of wood and / or wood-based material, in particular forms a multilayer composite panel which can be used as a roof element and / or wall element and / or floor element and / or ceiling element etc. Due to the high torsional rigidity of the components 1, break-sensitive materials can now also be arranged thereon.

   In the exemplary embodiment shown, a width 2 distances two longitudinal side surfaces 3 which run parallel to one another and which run at right angles to wide side surfaces 5 which are spaced apart from one another by a length 4.



   A height 6 dimensioned perpendicular to the width 2, as shown in this exemplary embodiment, spaced two single or multi-layer cover layers 7 running parallel to one another, between which a further layer 10 forming a height 9, in particular core layer 11, is arranged. A height 12 of the component 1 is formed by the sum of the height 6 of side walls 13 and thicknesses 14 of the cover layers 7. The appropriately flat, calibrated and / or ground, possibly multi-layered plate-shaped cover layers 7 form with their facing cover surfaces 15a a connecting surface 16a for the core layer 11 arranged between them.

   Broad side surfaces 17 facing one another of the side walls 13 oriented perpendicular to the top surface 15 a limit the width of the core layer 11, the core layer 11, as shown in this exemplary embodiment, bordering at least in regions on the broad side surface 17.



   Single-layer and / or multi-layered, preferably wooden strip-shaped spacing elements 18 distance the outer layers 7 from one another by a height 6 or support them against one another. The spacer elements 18, which are preferably oriented perpendicularly to the cover layers 7, form in the direction of the length 4 one or more wavy or meandering webs 19 spaced apart from one another in the direction of the length 4 and / or width 2, which in the form of a periodically repeating, continuous function or curve whose amplitude measured in the direction of the width 2 in the direction of the length 4 is the same or different values or



  Can have sizes. Of course, the spacer elements 18, which have a greater length than the length 4 of the component 1, can also run approximately parallel to the cover layers 7, so that apices 20 are supported on the mutually facing cover surfaces 15a of the cover layers 7. As shown in a preferred embodiment variant - according to FIG. 1 - there are at least two spacer elements 18, in particular webs 19, which are offset parallel to one another and by half a wavelength, and which are supported against one another in the unloaded state or only when there is a corresponding load, arranged, whereby these tangentially overlap or touch at least point-like, in particular line-shaped, in the region of apices 20. By mutually supporting the webs 19 high lateral forces can be absorbed.

   The webs 19, which are parallel and offset by half a wavelength from one another, delimit an airtight but vapor-permeable cavity 21 or chamber between two successive apices 20, which may be enclosed on all sides. The flat component 1, in particular the composite panel, therefore has a large number of contact areas

  <Desc / Clms Page number 9>

 che 22 separate cavities 21 or chambers. Expediently, partial areas of two mutually facing broad side surfaces 23, 24 of the webs 19 touch tangentially, where appropriate these can be roughened. The cavities 21 or chambers can of course also be diamond-shaped.

   If necessary, the spacer elements 18 can be arranged at a distance from one another in such a way that they only support one another in the loaded state, or they are prestressed to one another in the longitudinal direction and / or transverse direction of the component 1.



   An opening width 25, which is measured in the direction of the width 2 between two mutually facing webs 19 and which is between 200 mm and 700 mm, preferably between 300 mm and 500 mm, is smaller than one in the longitudinal direction between two successive contact areas 22 longitudinal opening width 26, which is between 800 mm and 3000 mm, preferably between 1000 mm and 1400 mm. A thickness 27 of the webs 19 is between 4 and 20 mm, preferably between 8 and 12 mm, and is preferably dimensioned equal to or greater than the thickness 14 of the cover layer 7, which is dimensioned between 2 and 20 mm, preferably between 5 and 10 mm ,

   Opposing narrow side surfaces 28 of the webs 19, which face the cover surfaces 15a of the cover layers 7 and preferably have the same or greater width than the thickness 27 of the spacer elements 18, are shaped with the cover surface 15a or connection surface 16a of the cover layers 7, at least in some areas - and / or non-positively connected, in particular form-glued or butt-glued together, etc. A thickness 29 of the straight webs 30 or side walls 13, which is between 5 and 40 mm, preferably between 20 and 35 mm, is less than or equal or larger, preferably larger than the thickness 27 of the webs 19.



   The self-supporting component 1 with two or more spatially deformed and / or multilayer cover layers 7 is connected to one another in a non-positive and / or positive manner at least in regions via a plurality of spacer elements 18 distributed over the cover surfaces 15a of the cover layers 7. The fastening points between the spatially deformed spacer elements 18 and the cover layers 7 are arranged in the longitudinal direction of the spacer elements 18 at points spaced apart from one another and in the direction transverse to the longitudinal direction at a distance from one another, the distance being greater than the thickness 27 of the spacer elements 18 and Spacer elements 18 are supported at least in partial areas for load transfer to adjacent spacer elements 18 in a load-transmitting manner or are connected to these in a displaceable manner.



   If necessary, the spacer elements 18 can also support each other and transmit the load only under load, so that they are slightly spaced apart from one another in the unloaded state.



   In order to enlarge the connecting surface 16b of the spacer elements 18, they can be adjusted in the direction of their height 9 at their two opposite edge regions with at least one ledge which is arranged at least over part of the length of the spacer elements 18 and which is connected to the broad side surface 23; 24 of the spacer elements 18 is connected.



   The ratio of the opening widths 25 transversely to the longitudinal direction to the opening widths 26 in the longitudinal direction is between 1: 2 and 1: 4, preferably between 1: 3.33 and 1: 3.5.



   The main advantage of the self-supporting and load-bearing and low-weight component 1 lies primarily in the fact that the wood portion of the cover layers 7 required for the cover layers 7 and spacer elements 18, which are preferably made of wood and / or wood-based materials, with a minimum span or length 4 of 6 m is smaller than 0.04 m3 / m2 cover area 15a; 15b, preferably between 0.01 and 0.035 m3 / m2 cover area 15a; 15b, and the wood portion of the strip-shaped spacer elements 18, in particular the webs 19; and / or the side walls 13, between 0.0015 and 0.01 m3 / m2 of the entire component 1.



    As an example, it should be mentioned that the thickness 27; the spacer elements 18, in particular the spatially deformed or corrugated or uneven webs 19 of 12 mm and the rectilinear webs 30 or the side walls 13 of 30 mm and at height 6; of the side walls 13 or



  Webs 19 of 140 mm a material content of about 0.00826 m3 / m2 is required. The uneven webs 19 with the opening width 25 of 400 mm and the height 9 of 140 mm require a material fraction of approximately 0.005 m3 / m2 and the straight webs 30 require a material fraction of approximately 0.0033 m3 / m2. Of course, the thickness of the side wall 13 can be different from the thickness 27 of the webs 19; be measured.

  <Desc / Clms Page number 10>

 



   The total material requirement for wood and / or wood-based materials with a thickness 14 of the cover layers 7 of 6 mm is then about 0.0203 m3 / m2. Two straight side walls 13 or webs 30 and seven spatially deformed or uneven or corrugated webs 19 are used as the basis for this, component 1, which is mounted in the longitudinal direction in the two opposite end regions and in the middle, and thereby several subregions between the support points, which have a length of 4 by 12 m and a width of 2 by 2500 mm.



   The following functional relationships are the basis for the calculation: m2uneven web / m2 building element = (height of spacer elements * 1 meter length * number of uneven webs * 1.06): (width of building element * 1 meter length) m2 more straight Web m2 component = (height of spacer elements * 1 meter length * number of straight webs): (width of component * 1 meter length) m3 uneven web m2 component = (height of spacer elements * 1 meter length * number of the uneven webs * thickness of the webs * 1.06): / M2 (width of the component * 1 meter length) m3 rectilinear web m2 component = (height of the spacer elements * 1 meter length * number of rectilinear webs * thickness of the webs) : (Width of the component * 1 meter length)
In this example, the straight webs 30 apply as side walls 13.



   The material share of wood and / or wood-based materials for this example breaks down as follows:
The total volume or room volume for a partial length of a partial area of 6 m is approximately 0.152 m3 / m2.



   The uneven webs 19 require 3.2%, the straight webs 30 about 2.1%, the cover layers 7 about 7.8% of the total volume or volume, so that the volume of the core layer 11 is about 92%.



   Of course, any structural design depending on the structural requirements is possible.



   The self-supporting, dimensionally stable component 1 with two or more cover layers 7, which has a plurality of spacer elements 18 which are arranged and spatially deformed over the cover surfaces 15a of the cover layers 7, are connected to the cover layers 7 in a force-fitting and / or form-fitting manner at least in regions and form them Core layer 11, which is formed by strip-shaped and uneven spacer elements 18, the core layer 11 forming between 50% and 98% of the volume of the component 1. The spacer elements 18 distributed over the top surface 15a of the top layer 7 require between 10% and 50% of the material volume of the component 1, the narrow side surfaces 28 of the spacer elements 18 facing the top surfaces 15a being oriented essentially parallel to the top surface 15a of the top layers 7 ,



   It should be pointed out that the component 1, in particular the cover layers 7 and / or the webs 19; can also be formed by a metallic or non-metallic material and / or a glass fiber reinforced plastic.



   Of course, there is also the possibility that the webs 19, which are offset by half the wavelength or run in phase and parallel to one another, preferably curved, are spaced apart from one another in the direction of the width 2 and therefore have a plurality of adjacent ones running in the longitudinal direction of the component 1 , Cavities 21 or chambers defined by wavy webs 19 and / or rectilinear webs 30 or side walls 13 are formed.



    Furthermore, the webs 19; and / or the webs 19 and the side walls 13 in the area of the apex 20 or the contact areas 22 are optionally connected to one another in a non-positive and / or positive manner.



   FIG. 2 shows a top view of several components 1 in a highly simplified and schematic illustration. The webs 19, which are spaced apart from one another and are formed with the thickness 29 and are offset from one another by half a wavelength, adjoin the broad side surface 17 of the side walls 13 in a line at least in regions

  <Desc / Clms Page number 11>

 and / or broad side surface 23; 24 of the straight web 30, which is formed with a thickness 29 corresponding to the distance.



   If a distance is kept free between two adjacent spacer elements 18, a media circulation, as is required for the rear and / or ventilation tasks, is possible via this cavity or channel formed by the spacing.



   The web 30 or the side wall 13 and the wavy curved web 19 delimit the cavity 21 or the chamber. Of course, it is also possible for the adjoining, wavy-curved webs 19 to run parallel to one another and to be in phase or out of phase and to be spaced apart from one another. One or more webs 30 can be arranged between the webs 19. Of course, the webs 19 can be connected to one another at one or more areas 22 which overlap or overlap the cover layers 7 and / or the web 30. Of course, several uneven webs 19 can also be arranged between the straight web 30 and / or the side walls 13.



   A plurality of components 1, which are butted against one another in a connection region 32 and endlessly connected or engaged with one another in a positive and / or non-positive manner, can be connected via one or more connecting elements 31 to form a large-area component 1. The components 1 to be connected, in particular the cover layers 7, preferably have a support which extends at least obliquely across the thickness 14 on at least one of the end faces 33 which face one another and which are arranged on the front end regions 33 and / or on narrow side surfaces of the cover layers 7 - And / or connecting surface 34. The support and / or connecting surface 34 preferably extends over the entire width 2 and / or length 4 or only over part of the width 2 and / or length 4 of the cover layers 7.

   One of the cover layers 7 expediently has at least one groove-like recess 35 with at least two support and / or connecting surfaces 34 which taper towards one another, into which an extension formed by the further component 1, which corresponds to it, projects or engages. A filler and / or adhesive layer is expediently arranged between the mutually facing support and / or connecting surfaces 34 of the two mutually facing components 1. Such a combination of the connecting elements 31 can above all create a large-area load-bearing one-piece component 1 that can be subjected to high tensile and / or bending loads.

   Of course, the side walls 13 can also be equipped with a connecting element 31 so that the side walls 13 which overlap in regions can be connected to one another.



   The webs 19 and / or 30 of the components 1 to be connected to one another can butt against one another in the connection region 32 or overlap or overlap in regions, where these can optionally also be connected in a non-positive and / or positive manner.



   As can be seen better from FIG. 3, the component 1 is equipped at the end region 33 to be connected to a further component 1 with the recess 35, into which the extension of the further component 1 projects. The spacer elements 18 and / or cover layers 7 of the components 1 which abut one another and / or overlap or overlap in the connection region 32 form a flat transition between the components 1 to be connected to one another and enable the non-positive and / or positive connection the formation of a force-transmitting and / or torque-transmitting connecting element 31. Of course, the facing spacer elements 18 and / or cover layers 7 can be traded in the connecting area 32.

   The webs 19 and / or the webs 30 distance the preferably multilayer cover layers 7 from each other by the height 9, minus one of the webs 19; receiving depth of grooves, as will be described in more detail. Furthermore, it would also be possible for a plurality of components 1 to be connected to one another in a form-fitting and / or non-positive manner via at least one connecting element on the facing surfaces 15b of the covering layers 7.



   As can also be seen in FIG. 3, the cover layer 7 can be formed in multiple layers.



  The cover layer 7 is formed, for example, by cover layers 37 spaced apart from one another by intermediate layers 36, which are connected to one another with a filler and / or adhesive layer or glue layer or synthetic resin. The intermediate layer 36 can be made by means of strips 38 made of wood and / or wood-based materials which are glued and pressed together or by a sandwich component, for example consisting of different types of plastic foam or one

  <Desc / Clms Page number 12>

 corresponding aluminum construction and wood or wood-based materials or the like.



   Of course, there is also the possibility that the intermediate layer 36 by means of a prepreg known from the prior art, in particular fiber prepreg, or by veneer layers which overlap or intersect in the longitudinal direction and / or in a direction crossing thereto and which are glued together are arranged optimized for the flow of force.



   For this purpose, at least one veneer layer of the cover layers 7 and / or the webs 19 expediently has; 30 and / or the side walls 13 in a plane perpendicular to their longitudinal extension and / or in a transverse to the longitudinal extension of the veneer layer at least one shaft S which corresponds to a further shaft S to be connected thereto. This creates an overlap or connection area between the individual veneer layers. The shafts preferably extend at a distance in the longitudinal direction of the opposite cover layers 7, and are therefore offset from one another. For a better overview, this was entered schematically in FIG. 2.



   Another embodiment, not shown further, is that in the longitudinal direction of the component 1, a plurality of spacer elements 18, in particular webs 19; 30 butt against each other or that they are arranged in an overlapping or overlapping position, at least in some areas, or if necessary connected. The connection regions formed are expediently arranged offset from one another in the longitudinal direction of the component 1, so that essentially no predetermined breaking point, which would result from the connection regions lying on the same plane, is formed. Of course, the cover layers 7 can also be formed in the same way.



   Of course, vapor barriers or fiber reinforcements or flame retardants etc. can also be arranged between the individual veneer layers. The strips 38, which are rectangular in cross-section and whose larger cross-sectional dimension is preferably oriented in the direction of the thickness 14 of the cover layer 7, extend between the cover layers 37, which expediently have the width 2 and / or the length 4. The strips 38 running in the longitudinal direction and / or transverse direction of the cover layer 7 are connected, in particular glued, to the cover layers 37.

   The cover layers 37 which cover or overlap the narrow sides of the strips 38 give the cover layer 7 a high bending and tensile strength, which, if appropriate, by arranging one or more strips 38 made of metal and / or plastic to further increase the bending strength in longitudinal and / or contribute transverse direction.



   As shown schematically, the spacer elements 18, in particular the webs 19 and / or 30, can have several layers, one or more intermediate layers 40 being arranged between cover layers 39, which are made, for example, of wood and / or wood-based materials or synthetic resins and / or fillers. or adhesive layers or glue layers or plastic foams or aluminum structures or the like. Of course, there is also the possibility that the cover layers 7 and / or the webs 19 and / or 30 are formed from board lamellae or from molded glued plywood or from molded chipboard with or without reinforcement or from metal etc.



   The receiving groove 41, which is recessed in at least one of the facing broad side surfaces 17 of the cover layers 7, positions or holds the webs 19 and / or webs 30 which extend in the longitudinal direction and / or in a direction transverse thereto and protrude into the receiving grooves 41. The cross-sectional profile corresponds here the webs 19 and / or webs 30 with the cross-sectional profile of the receiving grooves 41, with a width of the receiving grooves 41 being expediently dimensioned to be slightly larger than a thickness 27 or 29 of the webs 19 or 30, in which the difference in the dimensions of the width and thickness 27; formed fillet a sealing compound etc. or a plastic potting for the positioned support of the webs 19; 30 is brought in. Of course, the receiving groove 41 can also be formed by a fitting groove.



   4 shows a further embodiment variant of the component 1 in plan view and in a highly simplified, schematic representation. A plurality of webs 19 and webs 30 extend in the longitudinal direction between the two opposite side walls 13, a straight web 30 being arranged between at least two webs 19 offset by half the wavelength. The subsequent or adjacent undulating web 19 directly adjoins the preceding undulating web 19, so that optionally undulating webs 19 or undulating and linear webs 30 adjoin one another. Zumin-

  <Desc / Clms Page number 13>

 at least one of the cover layers 7 has a further one, via a filling or

   Adhesive layer 42 with the top surface 15b of the top layer 7 facing away from the core layer 11, which in particular forms a protective plate 44 which is formed from a non-combustible or flame-retardant material, in particular mineral material. Of course, the protective plate 44 can be provided with a fire protection coating. The non-combustible or flame-retardant protective plate 44 with the possibly non-combustible fire protection coating is connected to the cover layer 7 with a flame-retardant adhesive. A further possibility consists in that the layer 43 is made, for example, of a mineral wool for the purpose of thermal insulation or from a plastic, such as foamed polystyrene foam, or veneer layers or metallic materials or radiation-repellent materials, such as e.g.

   Lead, is formed.



   The protective plate 44 can also be made from a non-combustible, but foaming and insulating material in the event of a fire, for example potassium silicate or sodium silicate.



  Of course, the layer 43 can be formed, for example, by facade cladding, such as a decorative panel etc., or by a film formed from plastic or a film composite made from plastic or aluminum or sheet metal or veneer layer or water-repellent material, in particular impregnated materials.



   Another possibility is the integration of elements for the use of solar energy, in particular collectors or photovoltaics.



   Figures 2 and 4 show only exemplary designs with respect to the arrangement of the webs 19; 30 between the two opposite, preferably parallel, side walls 13. Of course, the webs 19, as shown, can also run parallel and in phase with one another and / or therefore that several webs 19 are offset by half the wavelength and further webs 19 run in phase with one another, are combined, between which linear webs 30 can be arranged at least in regions. The webs 19; and / or the side walls 13 and / or the cover layers 7 can be connected to one another in a force-fitting and / or form-fitting manner, in particular glued, glued, clamped etc.



   In the jointly described FIGS. 5 and 6, further design variants are shown in different views and in a highly simplified, schematic representation. The component 1 shown in FIG. 5 is essentially formed by the cover layers 7 having the width 2 and the length 4, the side walls 13 delimiting the width 2 and the spacer elements 18 having a height 9, in particular the webs 19 and / or 30, formed. The webs 19; which extend between the cover layers 7; 30 run in the direction of the length 4 and / or the width 2 of the component 1, as can also be applied to all other designs, it being possible for these to be formed by one or more layers.

   One of the two one or more layers and spatially deformed cover layers 7 has a curved, in particular one of the further plate-shaped cover layers 7 facing concave cover layers 7. Of course, the cover layer 7 opposite the flat cover layer 7 can form a convexly curved cover layer 7 in a direction facing away from it, or both opposite cover layers 7, which run parallel to one another, have the same convex or concave curvature, so that they essentially have a circular shape. Form arc segment. As a result, the most varied configurations of solid bodies or components 1 can be formed. The spacer elements 18 are preferably form-glued to the cover layers 7, as a result of which an increase in the load-bearing capacity can be achieved.

   The individual component parts required are expediently manufactured by CNC-controlled machines at economical production costs.



   If one of the two longitudinally opposite heights 9 of the core layer 11 or the height 12 of the component 1, formed by the height 9 and the thicknesses 14 of the cover layers 7, is made substantially higher than a height 9 opposite this, such a component 1 can be formed the attachment of a wear-resistant plastic covering to the top surface 15b of the top layer 7 facing away from the core layer 11, for example a skateboard track, which, in particular, after filling the cavities 21 or chambers with material, in particular recycling material, plastic material or the like, on the one hand damping effect and, on the other hand, minimizing noise by damping the sound waves.

  <Desc / Clms Page number 14>

 



   Another embodiment variant shown in FIG. 6 shows that at least one of the
Cover layers 7 or side walls 13 extend in the longitudinal direction and / or in a direction of the component 1 which crosses thereto, inclined to the opposite cover layer 7 or side wall 13 and, for example, forms a carrier element for a supporting structure.



   In this case, at least one cover layer 7 extending between the side walls 13 runs inclined to the cover layer 7 opposite this. Of course, both cover layers 7 can also run inclined towards one another or run parallel to one another. The webs 19 extending parallel to the side walls 13 extend between the cover layers 7; 30, whose height 9 decreases continuously depending on the angular course in the direction of the smaller dimension 6 of the side wall 13.



   Of course, all geometrical or constructive designs are possible in the arrangement of the cover layers 7 and / or the side walls 13 and webs 19 and / or 30. For example, the component 1 can have an approximately trapezoidal or square or rectangular, etc. cross-section in a plane perpendicular to its longitudinal extent, the cross-sectional dimensions of which can increase or decrease in the longitudinal extent.



   7 shows a further embodiment in plan view and in a highly simplified, schematic representation. The spacer elements 18 are formed by a multiplicity of cells 45, the walls 46 of which can consist of wood and / or wood-based materials or metal etc., preferably of aluminum, which are at right angles to the top surface 15a of the top layer 7 in the direction of a top layer 7 opposite this extend. The cells 45 have a quadrangular and / or hexagonal honeycomb structure, the walls 46 of which partially have single and double-walled partition walls 47 which are connected to one another, in particular glued or welded, etc. The side walls 13 and / or partitions 47 delimit hollow spaces or

   Chambers 21, which can optionally be filled with non-flammable or flame-retardant and / or heat-insulating materials.



   8 to 13, a component 48 according to the invention is shown in different views. The component 48 is formed by one or more components 1 that overlap at least in some areas. The component 1 is essentially formed by the cover layers 7 having the width 2 and the length 4, the side walls 13 delimiting the width 2 and the spacer elements 18 having a height 9, in particular the webs 19 and / or 30 and / or the cells 45 formed. As can be seen from the explanations, each of the designs can be equipped with or without noise-insulating, heat-insulating, non-flammable or flame-retardant materials, as has been shown schematically in part, in the cavities 21 or chambers.

   The broad side surfaces 5 limit the height 12, the height 12 in the longitudinal extension of the components 1 being dimensioned differently.



   As not shown further, one or more components 1 can also be connected, for example, with a glue binder or a supporting structure etc. in the form of a primary support structure.



   As can be better seen in FIG. 8, the multilayer component 48 is formed by at least two components 1 which are arranged one above the other and offset in the direction of the width 2 and / or length 4 and are connected to one another in a positive and / or non-positive manner. The multilayer components 48 arranged one behind the other and / or next to one another overlap in a connection region 49, where the components 48 on their mutually facing longitudinal side surfaces 3 and / or broad side surfaces 4 and / or on the outer mutually facing, overlapping cover surfaces 15b Cover layers 7 are positively and / or non-positively connected to each other. Of course, the connection area 32 can be formed in the region of the longitudinal side surface 3 for the connection of a plurality of components 48.

   The components 1 of the components 48, for example facing one of the contact surface 50 and lying on both sides, are preferably butted against one another. Between the mutually facing longitudinal side surfaces 3 and / or broad side surfaces 4 and / or on the mutually facing top surfaces 15b of the top layers 7, a filler or adhesive layer is arranged, which connects the two components 48 to one another in a force-locking manner.

   The components 1 of the components 48 which are opposite the contact surface 50 and face one another are preferably arranged at a slight distance from one another, so that after they have been placed against one another and connected

  <Desc / Clms Page number 15>

 A distance or an elastic expansion joint is formed between the two components 48, so that any manufacturing tolerances that occur, such as, for example, angular errors, etc., have no effect on, for example, a liquid-tight connection on the contact surface 50 of the components 48 to be connected to one another. If necessary, the components 1 in the connection region 49 can also be located on the mutually facing, overlapping broad side surfaces 5 or



  Cover surfaces 15b are interconnected. Furthermore, any stresses that may arise due to temperature differences can be compensated for by the distance. By stringing together several components 48, a large-area multi-layer surface element, in particular a floor element or wall element or roof element etc., can be formed.



   Of course, there is also the possibility that the components 1 are also offset from one another in the direction of their length 4 and / or width 2. A further possibility is that the component 1, for example facing the contact surface 50, projects beyond the component 1 opposite the contact surface 50 on the two opposite longitudinal side surfaces 3 and / or the front end region 33.



   As is also shown schematically, it is also possible, for example I-shaped spacer elements 18, which are formed from wood or preferably extruded profiles, etc., which are essentially formed by symmetrically facing U-shaped web sections, which have a common one have towering web and cross-webs. Between the towering web and the crossing webs there extends a circular-arc-shaped transition area which is large compared to the height 9 of the spacer elements 18. A chamber arranged between the opposing transverse webs serves to hold adhesive, in particular water-resistant glue, thereby increasing the connecting area 16b.



   As can be seen in particular in FIGS. 9 and 10, the cavities 21 or chambers are at least partially filled with heat-insulating and / or noise-insulating and / or flame-retardant and / or non-combustible fillers 51, which have a wide variety of properties and / or characteristics can, filled. The cavities 21 or chambers between the spacer elements 18 are sealed airtight on all sides by gluing to the cover layers 7, but are, if necessary, permeable to vapor. By forming a large number of cavities 21 or chambers, on the one hand a flat load distribution and a high shear strength of the component 1 and on the other hand a segmentation of the filler 51 is achieved.

   The filler 51 can be formed, for example, by bulk material, organic or inorganic substances, in particular chips, cellulose etc., or non-combustible rock wool or plastics or recycling material etc. The segmentation, above all, prevents signs of settlement, such as can occur, for example, when components 1 or 48 are installed in an inclined or vertical position. By arranging a large number of layers of fillers 51 having a different coefficient of thermal conductivity, a thermally optimized heat transfer can be achieved. Of course, the filler 51 can also be fiber-reinforced, for example.



   As can be seen from FIG. 10, the cavity 21 or chamber can also be filled only partially with fillers 51, a standing air layer being present in the space formed between the surface of the filler 51 and the top surface 15a. As a result, the filler 51 is not directly exposed to the constantly changing environmental conditions, as a result of which the effectiveness or the properties of the filler 51 are not impaired.



   As can be seen better in FIG. 11, it is of course also possible to arrange a plurality of components 1 one above the other, for example at least one further component 1 being arranged between two outer components 1 and having at least one long side surface 3 and / or wide side surface 4 of at least one of the outer components 1 protrudes. This enables a plug connection to be created between a plurality of components 1 lined up.



  Of course, in this embodiment, too, the cavities 21 or chambers of at least one component 1 can be completely or at least partially filled with the filler 51.



   FIGS. 12 and 13 now show two further designs in which the cavities 21 or chambers are completely or partially filled with fillers 51.



    As can be seen in FIG. 12, webs 19; the media circulation is taken over by at least one component 1, so that no additional

  <Desc / Clms Page number 16>

 Liche vapor barrier on the filled component 1 is required. In addition, the load capacity is increased by the further superordinate component 1. Through the arrangement of a diffusion-open cover layer 7, as can be achieved, for example, through passage openings protruding through the cover layer 7 or materials that are open to diffusion, media circulation is possible via one of the two components 1. As a result, additional production effort can be avoided by the additional arrangement or attachment, for example, of a laminated or glued-on vapor barrier on the component 1.

   In addition, there is also the possibility that a media circulation between several filled or unfilled components 1 can take place through the through openings or materials that are open to diffusion.



   As can also be seen from this figure, the spacer elements 18 can have at least one cover layer 39 and at least one intermediate layer 40. The intermediate layer 40 is formed by a plurality of longitudinal strips which extend in the longitudinal direction between the opposite and spaced-apart cover layers 39 of the spacer elements 18. These are expediently connected to the cover layers 39 at a distance from one another in the direction of the height 9, a longitudinal strip being arranged in the end regions facing the cover layers 7. It is advantageous here that on the one hand a larger connecting surface 16b is formed and on the other hand a thermal improvement can be achieved.



   FIG. 13 shows a further embodiment in which at least one component 1, in particular the cover layers 7, forms a defined target burn-up zone 52, the material composition of which is designed on the basis of the required fire resistance duration. This flame-retardant target burn-off zone 52 can consist, for example, of a metallic or organic or inorganic material. All materials known from the prior art can be used for this. Of course, this also includes materials that release water at elevated temperatures, such as aluminum hydroxides, alkali metal salts of silicates, hydrated phosphates, hydrated borosilicates etc. The core layer 11, which increases the strength, is also expediently made of flame-retardant or non-combustible materials or

   Fillers 51, which consist of one or more different components or



  Fabrics are composed, formed. It is particularly advantageous in this embodiment that after the component 1 equipped with the target erosion zone 52 has burned down, the tensile and / or compressive forces can be transmitted from the further component 1 having a sufficient residual load-bearing capacity. As can be seen from the individual figures, the spacer elements 18 of the components 1 arranged one above the other in the same cross-sectional plane can be arranged so as to overlap or offset with respect to one another in the direction of the width 2, which above all leads to a thermal improvement.



   Of course, the component 1 can at the same time, by at least partially filling the cavities 21 or chambers with fillers 51, form a noise-insulating and / or heat-insulating core layer 11, from which rear and / or ventilation tasks are performed, and / or form the target burn-off zone 52.



   For the webs 19 and / or 30 forming the spacer elements 18, veneer layers or board lamellae, etc., which overlap in the longitudinal direction and / or in a direction crossing thereto, are preferably formed. Of course, vapor barriers made of aluminum or plastic films or fiber reinforcements or flame retardants or heat-insulating materials and / or metallic materials etc. can also be arranged between the individual veneer layers. The spacer elements 18 are butt-glued to the cover layers 7, in particular at their connecting surface 16a, and / or form-glued to the receiving groove 41.

   The cover layers 7 can, of course, be formed by all of the boards known from the prior art, such as, for example, fiber boards, in particular medium-density fiber boards MDF, or OSB or laminate boards or compact boards or coated chipboard or sandwich boards etc. Of course, the spacer elements 18 of a plurality of components 1 to be connected to one another can be equipped with a shank and / or a finger joint on their front, mutually facing narrow side surface, so that an endless component can be produced.



   Finally, it should also be mentioned that the airtight, but expediently vapor-permeable cavities 21 or chambers are provided with a passage opening equipped with an air-impermeable membrane or steam valve, one in the cavities 21 in particular

  <Desc / Clms Page number 17>

 pressure built up in the chambers when exposed to sunlight or high temperature differences can be adjusted to atmospheric pressure.

   The opposite end regions 33 of a component 1 or, in the case of several interconnected components 1, the end region 33 of the first component 1 and the end region 33 of the last component 1 are expediently provided with at least one end strip, in which at least one air-impermeable strip Membrane or a steam valve is arranged, whereby the steam pressure can escape through the membrane or steam valves in the longitudinal direction of the component 1. The vapor permeability is made possible by spacer elements 18 spaced apart from one another and / or by vapor permeable spacer elements 18 or cover layers 7.



   In the jointly described FIGS. 14 and 15, a partial area of the component 1 is shown in a side view, cut and shown in a highly simplified, schematic representation. The multiple layers 53; having cover layers 7 are mutually by the height 9 of the spacer elements 18, in particular the webs 19; spaced apart and form the height 12 of the component 1. The layers 53; formed from wood and / or from materials different from wood and / or wood-based materials; 54 have two or more layers 55; at least one of the layers 55; a plurality of veneer sections 57; respectively.

   Has veneer layers within a cover layer 7 and / or a spacer element 18 of the component 1, whereby a veneer section 57; or veneer layers formed connection area 59 of a layer 55; 56 is completely overlapped by a further layer 55 of the same layer 53 or the layer 56 of the other layer 54 which runs plane-parallel to this. As a result, the connection areas 59 or joints of the individual layers 55; in the cover layer 7 and / or at least one butt of the spacer elements 18, offset in the longitudinal direction to each other.

   The individual layers 55; of the cover layers 7 are symmetrical or asymmetrical with respect to a central plane of the component 1 and are connected to one another.



   As can be seen from the figures, between the mutually facing side surfaces, in particular end face surfaces, of the veneer sections 57 of the layer 55 and between the mutually facing side surfaces, in particular end face surfaces, of the veneer sections 58 of the layer 56, an abutment 60, which is approximately vertical in the longitudinal extension of the veneer section 57; 58 runs, trained. Due to the multilayer structure of the cover layers 7, each joint 60 of a layer 55; 56, from a further layer 55; 56 completely overlaps, so that the individual layers 55; 56 is required, but is also possible.



   The layers 53 facing the spacer elements 18, in particular their veneer sections 57 of the individual layers 55 arranged one above the other and one behind the other, are aligned with the fiber direction 61 running transversely in the longitudinal direction of the cover layer 7, the veneer sections 58 also including the further layer 54, which preferably overlaps the layer 53 are aligned in the longitudinal extent of the cover layer 7 approximately parallel fiber direction 62. The longitudinally oriented fibers of the outer layer 54 can in particular absorb or dissipate tensile forces and compressive forces can be absorbed by the inner layer 53 with fibers running transversely to the longitudinal direction. Therefore, the fibers of the individual layers 53; 54th

   The outer layer 54 is preferably provided with between two and seven, preferably between three and five layers 56 of veneer sections 58 which are arranged one above the other and which are connected, in particular glued, to one another via facing broad side surfaces 63 of the veneer sections 57 or 58. The inner layer 53 is preferably provided with between 1 and 3, preferably 2 layers 55 of veneer sections 57 arranged one above the other. Due to the large-area gluing on the broad side surfaces 63, it is no longer necessary to arrange the veneer sections 57; to connect 60 at their joint. Of course, an inverted arrangement of the layers 53; 54 possible.

   Of course, any arrangement of the individual layers 53; of the two opposite cover layers 7 possible. The layer 53 and / or layer 54 can also be formed by strips made of wood, which are aligned in the longitudinal direction and / or in a direction crossing thereto and which are connected to one another in the connecting region 59 or are connected to one another in an overlapping or overlapping or finger-jointed manner.



   As can be seen in FIG. 15, there is also the possibility that at least one of the layers 53; 54, in particular the outer layer 54, through a material different from wood,

  <Desc / Clms Page number 18>

 is formed in particular by a thin-walled sheet 64 or a plastic whose thickness 65 is between 0.2 and 1.0 mm, in particular between 0.2 and 0.5 mm. Here, the sheet 64 can also take over the function of the vapor barrier or a roof skin. Of course, there is also the possibility of arranging the sheet metal 64 between the layer 53 and the spacer elements 18 and / or between the two layers 53 and 54 and of connecting them, in particular gluing them together.

   The layers 55; are bonded together using a waterproof and fully reacted and irreversible component adhesive, especially glue.



   Such a construction of the cover layers 7 can of course also be used for the spacer elements 18 and side walls 13, so that, for example, the outer cover layers 39 run through veneer sections having fibers running transversely to the longitudinal direction of the spacer elements 18, and the intermediate layer 40 run through several parallel to the longitudinal direction of the spacer elements 18 - De fibers having veneer sections is formed. A butt 66 is formed between the veneer sections of the layers.



   Another embodiment, not shown, is that the component 1 has a plurality, in particular more than two cover layers 7, between which the spacer elements 18 connected to the cover layers 7 are arranged, the two outer cover layers 7 expediently having a plurality of layers 53; and the intermediate covering layer 7 has at least one of the layers 53 or 54. The spacer elements 18 between the two cover layers 7 can be arranged in the longitudinal direction and / or in a direction of the component 1 that crosses or crosses. If the spacer elements 18 are arranged in the longitudinal direction between the two cover layers 7, they can be offset with respect to one another in the width direction and / or longitudinal direction.



   The self-supporting and load-bearing component 1 according to the invention can also be used as a roof element extending between opposite gable walls, which is placed or supported on the gable walls and / or on one or more partition walls. The top surface 15b of the component 1 opposite the interior of the house can be equipped with crossbars for receiving or holding the roof tiles even before it is installed.



   Another embodiment, not shown further, for the component 1 consists in that at least one of the cover layers 7 has at least one diffusion-tight layer 53; in particular layer 55; or at least one further layer 43 arranged on the cover layer 7 and the further cover layer 7 at least one hygroscopic and / or liquid-storable layer 53; 54, in particular layer 55; has, which receives the condensate accumulating in the core layer 11 of the component 1, stores it and / or releases it to the building room air. The diffusion-tight layer 53; or layer 43 can be formed by a film made of plastic, aluminum etc. or by metallic materials.

   The airtight and force-transmitting cover layer 7 facing the interior of the room expediently has closable openings, pores, etc.



   In the jointly described FIGS. 16 to 18, the self-supporting and load-transferring component 1 is shown in different views and in a highly simplified, schematic representation. The component 1, which is formed at least in part from wood-based material, is designed as a multilayer composite panel and can be used as a large-area component 1, for example for wall, ceiling or floor elements. In accordance with this exemplary embodiment, the width 2 distances two longitudinal side surfaces 3 which run parallel to one another and which run at right angles to broad side surfaces 5 which are spaced apart by the length. The height 6, measured perpendicular to the width 2, distances two parallel or single-layer cover layers 7 running parallel to one another, between which the core layer 11 forming the height 9 is arranged.

   The height 12 of the component 1 is formed by the sum of the height 6 of the side walls 13 and the thicknesses 14 of the cover layers 7.



   In the simplest case, as is not shown further, the component 1 consists of a cover layer 7 and the core layer 11 delimited by the side walls 13. The core layer 11 is formed by strip-like spacer elements distributed over the inner cover surface 15a of the cover layer 7 18 formed. The core layer 11, in particular the spacer elements 18, is or are via at least one connecting and / or strengthening means 70 with their top surface 15a, which preferably extends over the entire length of the spacer element 18

  <Desc / Clms Page number 19>

 facing connection surfaces 16b at least with a part of the cover surface 15a of the cover layer 7 non-positively and / or positively.

   At least one connecting region 71 extending over the length 4 of the spacer element 18 is formed between the spacer element 18 and the cover layer 7. For the purpose of adapting to different uses of the load-bearing component 1, a plurality of connection regions 71, as shown in FIG. 16, can be arranged between the spacer element 18 and the cover layer 7 in the longitudinal direction of the spacer element 18 at locations 72 spaced apart from one another, in which the connecting and / or strengthening means 70 are arranged.



   According to this exemplary embodiment, the cover layer 7, which is limited in thickness 14 by the inner cover surface 15a and parallel to this outer cover surface 15b, is formed by a wood or wood-based material elements 73, in particular wood chips and / or wood-like fibrous materials, which are in spatial confusion, at least in regions between the cavities 75 lying on the wooden or wooden material elements 73 and / or on the pores 74 formed on the surfaces of the wooden or wooden material elements 73 are formed plate 76. The plate 76 designed in this way can be formed, for example, by a particle board (FPY) or medium-density fiber board (MDF) or laminated beach lumber board (LSL) or oriented beach board board (OSB). An OSB coarse particle board 76 is expediently used for the cover layer 7.

   The OSB panels 76, which are largely known from the prior art, are mostly constructed in several layers and in one piece, of which the two outer cover layers 37 or cover layer areas are longitudinally oriented and the intermediate layer 36 or the intermediate area are transverse-oriented large-area wood or wood-based material elements 73, in particular Chips. The two outer cover layers 37 of the OSB panel can of course vary in thickness depending on the load to be absorbed.



   The cover layers 37 or cover layer areas delimiting the intermediate layer 36 or the intermediate area form at least part of the thickness 14 of the cover layer 7. Of course, several layers 36 and / or 37 can also be provided. The thickness of the two outer cover layers 37 or cover layer areas is between 0.3 mm and 8 mm, in particular between 0.5 mm and 2 mm, for example 0.8 mm. As a result, the load-bearing capacity in the longitudinal direction or the length 4 of the component 1 can be significantly increased or increased. The wood or wood material elements 73 or chips, in particular the cover layers 36 or the cover layer area of the cover layers 7, have a cross section of approximately 75 mm in length and 0.7 mm in thickness.



  Another embodiment of the multi-layer OSB board 76 is that the wood or wood-based material elements 73 or chips of the top and middle layer 36, 37 or of the top layer area or intermediate layer area are approximately 120 mm to 350 mm, for example 150 mm long, possibly waterproof, glued veneer strips are formed. This embodiment is distinguished above all with regard to the reduction of undesirable, for example moisture-related changes in shape of the cover layer 7. Cover layers 7 of this type, in particular made of OSB panels, usually have a high proportion of wood, in particular over 96%, for example made of thinning wood, and, due to the crosswise gluing of the two outer cover layers 37 to the intermediate layer 36, can bear high loads in the longitudinal and width directions take up.

   Furthermore, these panels 76 are characterized by their high weather resistance. The thickness 14 of the cover layer 7 is between 8 mm and 14 mm, for example 10 mm.



   As can be seen from FIG. 16, the spacer elements 18 extend in the direction of the length 4 of the component 1 and are oriented perpendicular to the inner cover surface 15a and the connecting surfaces 16b of narrow side surfaces 28 of the spacer elements 18 run parallel to that of the connecting surfaces 16a receiving inner, planar top surface 15a of the top layer 7 and form the connecting region 71 between them. As a result, the inner cover surface 15a receiving the connection surface 16a and the narrow side surface 28 receiving the connection surface 16b run in the same plane and the spacer element 18 and the cover layer 7 are arranged perpendicularly to one another and butt-connected to one another.

   As a result, no groove-like recesses receiving and supporting the spacer elements 18 are required to fix the spacer elements 18 with respect to the cover layer 7.



   The spatially deformed, in particular wave-shaped in its longitudinal extension spacer 18 is by a wood or woodwork in spatial confusion

  <Desc / Clms Page number 20>

 material elements 73, in particular wood chips and / or wood-like fibrous materials, with cavities 75 lying at least in regions between the wood or wood material elements 73 and / or pores 74 formed on a surface of the wood or wood material elements 73, plate strips 77, in particular chipboard ( FPY), medium density fiberboard (MDF) or oriented beach board (OSB) or laminated beach lumber (LSL). The spacer element 18 is expediently formed by a plate strip 77 made of a flexible chipboard (FPY). Such single-layer, three-layer or multi-layer flat pressed plates or

   Flexible particle boards are already known from the prior art.



   As can be seen from this preferred embodiment variant, a plurality of spacer elements 18, which are offset parallel to one another and by half a wavelength in each case, are arranged over the inner cover surface 15a, with turning areas 78 of two spacer elements 18 running parallel to one another abutting or supporting one another.

   The opening width 26, which is dimensioned in the direction of the longitudinal extent of the component 1 between two successive turning areas 78, is between 800 and 3000 mm, in particular between 2000 and 2800 mm, for example 2500 mm, and is preferably larger than the opening 25 dimensioned transversely to the longitudinal extent of the component 1 between two turning areas 78 of two spacer elements 18 running next to each other and is between 200 and 700 mm, in particular between 300 and 500 mm, for example 400 mm. This results in a ratio of the lateral opening width 26 to the transverse opening width 25 between 1: 4 and 1: 4.3.



   The spacer elements 18 are expediently connected to one another in a force-fitting and / or form-fitting manner in their mutually facing broad side surfaces 23, 24 in the turning region 78 or in the contact regions 22 formed by them, and form an integrally formed core layer 11. The cavity 21 or the chamber is delimited by partial sections of two adjacent spacer elements 18 and / or a partial region of the spacer element 18 and the side wall 13 between two successive turning regions 78 and the preferably two cover layers 7. The thickness 27 of the spacer element 18 is between 4 mm and 8 mm, for example 6 mm. As already explained above for the cover layer 7, the spacer element 18 can - as is not shown further - be constructed in multiple layers and the two outer cover layers 39 or

   Cover layer areas and the intermediate layer 40 or intermediate layer areas.



   The cover layers 39 or cover layer areas and the intermediate layer 40 or intermediate layer areas of the cover layer 7 and / or the spacer elements 18 can, for example, have a different density and / or a crossed orientation of the wood or wood-based material elements 73 or from wood or Wood material elements 73 of different materials, such as plastic and / or metal etc., are formed. The spacer element 18 can therefore be formed by the previously described three-layer or multilayer chipboard strip or by an OSB chipboard strip. Of course, the cover layer 7 and / or the spacer elements 18 can also have at least one reinforcement layer, which can be covered by a fiber prepreg and / or resin-impregnated fiber mats e.g.

   B. is formed with coal and / or glass and / or nets and / or knitted fabrics of the same or different types of threads or fibers for fabric reinforcement.



   As can be seen more clearly from FIG. 17, the component 1 is shown in a highly simplified manner with two cover layers 7 and between these spacer elements 18, at least one connection area 71 between the first lower and further upper cover layer 7 and the spacer elements 18 is formed. As already mentioned above, the cover layers 7 are formed from the OSB plate 76 and the spacer elements 18 from the FPY plate strip 77, the strip-like or thread-like wood or wood material elements 73 of the cover layer 37 of the cover layers 7 facing the spacer element 18 are essentially aligned in the longitudinal direction of the component 1 and the intermediate layer 36 of the cover layers 7 is transverse to the longitudinal direction of the component 1.

   Due to the manufacturing process of the cover layers 7, the cavities 75 are enclosed between the wood or wood material elements 73 and pores 74 are irregularly formed over a surface of the wood or wood material elements 73. The cavities 75 in the area of the outer cover layer 37 or cover layer regions facing the spacer element 18 run essentially parallel and / or at least inclined to the inner cover surface 15a and / or crossed to one another.

   Essentially crossed and / or inclined to the wood or wood material elements 73 of the outer cover layer 37

  <Desc / Clms Page number 21>

 Wood or wood-based material elements 73 of the intermediate layer 36 of the cover layers 7 enclose the cavities 75 formed between the wood or wood-based material elements 73 and essentially transverse to the longitudinal extension of the wood or wood-based material elements 73 and / or crossed with one another.



   The spacer elements 18 essentially formed by the plate strips 77 made of wood material preferably have wood or wood material elements 73 which are arranged crosswise over their thickness 27 and which likewise have pores 74 arranged irregularly distributed over their surface. The wood or wood material elements 73 of the spacer elements 18 run essentially in several spatial directions inclined to the connecting surface 16b or the inner cover surface 15a of the cover layer 7. As is known from the prior art, the wood or wood material elements 73 have those made of FPY formed plate strips 77 or spacer elements 18 a main dimension 79, in particular length or width of about 1 mm to 10 mm, for example 6 mm.



   At this point it should be noted that any combination of the cover layers 7 and spacer elements 18 formed from wood-based material, such as FPY and FPY or OSB and FPY or FPY and OSB or OSB and OSB, is possible.



   At least the longitudinally oriented wood or wood material element 73 of the cover layer 7 formed from OSB, which is arranged essentially parallel to the inner cover surface 15a and in a surface region adjacent to the cover surface 15a, in particular the cover layer 37, is in the connection region 71 for the spacer element 18 in its main dimension 79 is at least larger than the thickness 14 of the spacer element 18 or is a multiple of the thickness 14 of the spacer element 18.

   To connect the spacer element 18 in a connecting region 71 running over the entire length of the connecting surface 16b or in a plurality of spaced apart locations 72 on the connecting surface 16b, the connecting and / or strengthening means 70 is formed by these spaced apart connecting regions 71 arranged in the connection area (s) or connection areas 71 spaced apart from one another between the spacer element 18 and the cover layer 7.

   The curable, flowable connection and / or solidifying agent 70 is by an adhesive, preferably up to 2 mm pore or cavity filling adhesive, in particular urea-formaldehyde condensation resins or melamine-formaldehyde condensation resins or melamine-urea condensation resins or Phenol-formaldehyde condensation resins are formed. Of course, the cold or hot curing connection and / or strengthening agent 70 can also be made using a resortin adhesive or a preferably thermosetting plastic adhesive, e.g. B. PVAC or PUR, are formed.

   For joining the core layer 11 with at least one cover layer 7, it is of course possible to use all adhesives known from the prior art which have a viscosity such that it can diffuse into the connecting surfaces 16a, 16b of the cover surface 15a and the spacer element 18. Viscosity viscous adhesives can be changed in their viscosity at least during the application to the connecting surfaces 16a, 16b by microwave energy or temperature influence etc. in such a way that a safe diffusion within the connecting surfaces 16a, 16b is possible. Of course, the connecting and / or strengthening agent 70 can also be formed by a one- or two-component or multi-component adhesive, in particular glue, with or without an extender and filler and / or hardener.

   The curable, flowable adhesive applied to the narrow side surface 28 and / or in the connection area 71 for the spacer element 18 on the outer layer 7 diffuses into the interior of the spacer elements through the open-pored inner cover surface 15a and narrow side surface 28 or their open-pored wood or wood material elements 73 18 and cover layer 7. The flowable adhesive in the initial state is by the orientation of the wood or wood material elements 73 in the cover layer 7 substantially in the longitudinal direction and / or partially in the width direction and over part of the thickness 14 of the same and by the orientation of the wood or Wood material elements 73 in the spacer element 18 are essentially absorbed in the direction of the height 9 thereof.



   As a result, a connection with the wood or wood material elements 73 and / or pores 74 and / or cavities 75 between the cover layer 7 and the spacer element 18 is made in a simple manner in the connection region 71 between the cover layer 7 and the spacer element 18 hardened connection and / or hardening means 70 formed connection and / or hardening zone 80. This connection and / or consolidation zone 80 has

  <Desc / Clms Page number 22>

 a higher mechanical strength, in particular pressure, tensile, bending, shear and torsional strength, compared to regions of the cover layer 7 and the spacer element 18 adjacent to these.

   The connection and / or consolidation zone 80, which extends between the cover layer 7 and the spacer element 18 over part of the thickness 7 and height 9, has an approximately T-shaped joint cross section in each of these connection regions 71, a maximum joint cross section 81 in the direction of the Spacer element 18 projecting first area of the connection and / or strengthening zone 80 is limited by a minimum thickness 27 of the spacer element 18 and a minimum joining cross-section 82 of a further area of the connection and / or strengthening zone 80 projecting in the direction of the cover layer 7 is larger, than the maximum thickness 27 of the spacer element 18. As a result, when two cover layers 7 are arranged, an approximately I-shaped joining cross section (not shown) is formed between the cover layers 7 and a spacer element 18.

   The thickness of the connecting and / or hardening zone 80 projecting into the cover layer 7 and the spacer element 18 is several times greater than a maximum surface roughness of the cover layer 7 and the spacer element 18 and formed in the connection area 71 of the abutting cover layer 7 and the spacer element 18 and is approximately between 0.02 mm and 8 mm, in particular 4 mm, for example 4 mm. The connection and / or consolidation zone 80 is flame-retardant and / or fire-retardant.



   It should be pointed out that the connection and / or consolidation zone 80 formed by the hardened connection and / or strengthening means 70 in the connection areas 71 was only shown schematically in FIG. 17 and tests have shown that these approx is formed in the shape of a hedgehog and the individual spike-like arms of the connection and / or consolidation zone 80 hook into the claw-like manner with the wood or wood-based material elements. Furthermore, the component 1 can absorb higher tensile and compressive loads due to the connection and / or consolidation zones 80 formed in the connection areas 71.



   As further entered in FIG. 17, there is of course also the possibility that at least one of the cover layers 7 on the outer cover surface 15b facing away from the core layer 11 and / or in the area of the core layer 11 between the spacer elements 18 with at least one ner further layer 43, as shown in dash-dotted lines, is provided, which is preferably formed from a fiber mat made of renewable raw materials with a porous surface and with an inorganic insulating material, in particular silicate rock powder.



  This fiber mat is expediently non-detachably connected to the top surface 15a, 15b via the filler or adhesive layer 42. Of course, there is also the possibility that the layer 43 arranged on the inner and / or outer cover surface 15b is formed by a plastic or film or paint or lacquer coating or melamine resin coating. Furthermore, this layer 43 can be formed by an optionally colored or at least partially pressed-in adhesive layer, such as melamine resin-formaldehyde resin or phenol-formaldehyde resin, or at least partially pressed into the outer cover layer 37 of the cover layer 7, or from a plastic film. In addition, it is also possible to design the outer cover surface 15b to be smooth or structured, at least in partial areas.



   For a better understanding and to clarify the low material content or volume, a two-field system with an overall length of component 1 of 12 m and length 4, measured between two support points spaced apart in the longitudinal direction of component 1, of 6 m and the width, is taken as an example 2 of 2 m, a transverse opening width 25 of 400 mm and a lateral opening width 26 of 2500 mm:
With the thickness 27 of the spacer elements 18, in particular the spatially deformed or corrugated or uneven webs 19 of 6 mm and the height 9 of the webs 19 of 140 mm, a material proportion of approximately 0.0043 m3 of uneven web / m2 results component.



    With the thickness 27; the spacer elements 18, in particular the straight webs 30 or the side walls 13 of 12 mm and at the height 6; the side walls 13 or webs 19 of 140 mm results in a material proportion of approximately 0.00168 m3 of uneven web / m2 of component.



   The total material requirement of the flat and uneven spacer elements 18 is then approximately 0.00598 m3 / m2 component and the cover layers 7 approximately 0.024 m3 / m2 component. As a basis for this, two rectilinear side walls 13 or webs 30 and ten spatially deformed or uneven or corrugated webs 19 are used. As a correction factor for the uneven webs

  <Desc / Clms Page number 23>

 19, a value of 3% was determined and was accordingly taken into account in calculations for the material fraction m3 of uneven web / m2 of component.



   The core layer 11 forms approximately between 50% and 98% of the volume of the component 1, the flat and / or uneven spacer elements 18 distributed over the inner cover surface 15a of the cover layer 7 between 10% and 50%, in particular between 18% and 25%, form for example 20% of the material volume of the component 1. It should be noted that, of course, the height 9 of the core layer 11 can vary and the volume of the component 1 and the material volume of the component 1 and the material proportion of the spacer elements 18 result from this variation. Thus the height 9 can be between 80 mm and 350 mm, in particular between 120 mm and 300 mm, for example 140 mm.



   It is particularly advantageous here that the structural design of the core layer 11 and the flat cover layers 7 spanning it over a span or length 4 of 6 m means that the height 9 of approximately 140 mm and the thickness 27 of approximately 6 mm of the spacer elements 18 and the thickness 14 of approximately 12 mm of the cover layers 7 is sufficient to accommodate a payload of approximately 1 kN / m2.



   FIG. 19 shows a partial area of the cover layer 7 and a partial area of the spacer element 18 detached from the cover layer 7 in a highly simplified schematic illustration. It can be seen that after the spacing element 18 and / or the cover layer 7 has been subjected to an inadmissible test force which is essentially perpendicular to the cover layer 7, the protruding into the cover layer 7, consisting of the wood or wood-based material elements 73 and the connecting and / or hardening agent 70 existing area of the connection and / or hardening zone 80 is torn out.

   Due to the enlargement of the lateral joining cross section 81 in the area of the cover layer 7 compared to the maximum joining cross section 82 in the spacer element 18, there is a high resistance to tearing of the spacer element 18 from the cover layer 7 and thus a lifting of the cover layer 7 from the spacer element 18.



   Tests have shown that the shear strength can be achieved up to 7 N / mm2 even if the spacer 18 and the cover layer 7 are butt bonded.



   20 shows an exemplary application of a large-area component 1 as wall element 83 and / or ceiling element 84 for a building in a side view and in a greatly simplified schematic illustration. The component 1 has at least one cover layer 7 and spacer elements 18 distributed over the inner cover surface 15a, which are connected to the cover layer 7 in a positive and / or non-positive manner. As already described in detail above, the cover layer 7 and spacer elements 18 are formed from wood-based materials. In the exemplary embodiment of the wall element 83 shown, the width 2 distances two longitudinal side faces 3 which run parallel to one another and which run at right angles to wide side faces 5 which are spaced apart by the length 4.

   In contrast to the previously described embodiment variants, the spacer elements 18 formed from wood-based material are transverse to the longitudinal extension or



  Length 4 arranged and running parallel and offset by half a wavelength to each other. The wall element 83 and the ceiling element 84 are fastened by means of connection connecting parts 85 with support elements 86 oriented perpendicularly to a horizontal foundation plate 85. The horizontal flat foundation plate 86 is supported on a foundation floor 88 and is formed from concrete with or without probation. The support elements 87, which are spaced apart from one another by the length 4 of the wall element 83, are inserted into the foundation plate 86 and connected to the latter in a fixed manner. The components 1 are connected to them in a non-moving or floating manner via connection connecting parts 85 arranged between the support elements 87 and the components 1.

   The connection connecting parts 85 can be formed, for example, by profile-like angle irons, which extend on the wall element 83 at least over part of the width 2 or height on the opposite broad side surfaces 5 and / or longitudinal side surfaces 3.



   By providing a slight gap between the lower longitudinal side surface 3 and the foundation plate 86, the wall element 84 is held or supported essentially exclusively by the support elements 87. The structural design of the wall elements 84 corresponds to that already described in FIGS. 1 to 19 and can equally be applied to this embodiment in FIG. 20.



   The component 1 according to the invention is ideally suited for use in earthquake areas.

  <Desc / Clms Page number 24>

 provided structures, in particular buildings, where soft foundation floors 88, in particular sandy soil, are present, since in the event of an earthquake the dynamic forces transmitted to the support elements 87 and acting essentially parallel to the component plane of the wall element 84 are absorbed by the component 1 through its predeterminable vibration behavior can be. This is possible in that the component 1 is formed over a large area and with a low mass and therefore a high oscillation amplitude. For this purpose, the component 1 has the corrugated spacer elements 18, which are connected to the inner cover surface 15a.

   Of course, the vibration behavior of the component 1 can also be significantly influenced by the elasticity of the hardened connecting and / or strengthening means 70, in particular adhesive, and the arrangement of the connecting areas 71 and the thickness 14, 27 of the cover layer 7 and spacer elements 18. Due to the forces acting on the component 1 during the earthquake, the latter is essentially elastically deformed in the longitudinal direction thereof. This effect is known to the person skilled in the art under the action of a pane.



   The type of connection and the different structural configurations of the component 1 are known from the previously described FIGS. 1 to 19.



   As can further be seen from this figure, one of the cover layers 7 is formed by a plastic plate, in particular a transparent and possibly colored plastic plate, for example a plexiglass.



   FIG. 21 shows a schematic representation of the manufacturing method of the self-supporting, load-bearing component 1 in a view and in a highly simplified, schematic representation. It should be noted that in this figure the component 1 has the lower and upper cover layers 7, between which the core layer 11 consisting of a plurality of spacer elements 18 is arranged. Of course, this component 1 can also have only the lower cover layer 7 and the core layer 11, after which the method must be modified accordingly.



   The production system 89 for the production of the component 1 consists of at least one preferably endlessly rotating conveyor device 90 for the lower cover layer 7, which is endlessly supported on a first roll about an axis of rotation 91, and at least one first layer arranged adjacent to the inner cover surface 15a of the lower cover layer 7 Applicator roller 92 for the connecting and / or strengthening means 70, which rotates about an axis 94 running transversely to the transport direction - according to arrow 93 - and a container 95 downstream of the first applicator roller 92 for the - in accordance with arrow 93 metered supply of the filler 51 and at least one further application roller 92 arranged downstream of it in the transport direction - according to arrow 93 - which rotates about the axis 94 which runs transverse to the transport direction - according to arrow 93 -

   and at least one vibrating device 96 arranged adjacent to the outer cover surface 15b facing away from the core layer 11. The drivable conveyor device 90, in particular a belt conveyor, has a length that is preferably several times greater than the maximum format length and at least slightly wider than a maximum format width of the component to be produced 1. The lower cover layer 7, which can be rolled off endlessly from the first roll, is continuously moved at a predeterminable speed in the transport direction - according to arrow 93 - via the rotating conveyor 90.

   The application roller 92 assigned to the lower cover layer 7 or the inner cover surface 15a is designed to be relatively adjustable relative to the inner cover surface 15a by means of adjusting elements (not shown in particular), in particular pneumatic cylinders, hydraulic cylinders etc., as a result of which the application of connection and / or solidifying means 70 can take place on the inner cover surface 15a.



   After the at least area-wise, preferably full-area application of connecting and / or strengthening means 70 to the inner cover surface 15a, the core layers 11 formed with a length 97 are placed on the inner cover surface 15a in a row in immediate succession. The core layers 11 arranged one behind the other or their spacer elements 18 can be butted against one another in their connecting regions 32 or brought into a partially overlapping position or shifted, as has already been described in FIG. 3.



  As a result, an essentially endless web-like flat core layer 11 is formed, as can be seen from FIG. 21. In the connection area 32, the core layers 11 arranged directly one behind the other can be connected to one another in a positive and / or non-positive manner.

  <Desc / Clms Page number 25>

 



   Subsequently, the cavities 21 or chambers, as shown in FIGS. 9, 10, 12, 13, are filled with filler 51 at least in regions, or a layer or



  Fiber mat 43 inserted. For better distribution of the filler 51 in the cavities 21 or



  Chambers is at least briefly subjected to vibrations on the lower cover layer 7 and the core layer 11 via the vibrating device 96. After the cavities 21 or chambers have optionally been filled, if an upper cover layer 7 is provided, the connecting and / or strengthening agent 70 is again applied to the upper narrow side surfaces 28 of the spacer elements 18 via the further applicator roller 92.



  In this case, the application of the connecting and / or strengthening agent 70 over the entire length 97 of the core layer 11 to the narrow side surfaces 28 or exclusively to the longitudinally spaced, provided connecting areas 71 or points 72, as this is schematically shown by crosses on the narrow side surfaces 28 Spacer elements 18 are indicated in FIG. 16. For this purpose, the further applicator roller 92 is designed to be relatively adjustable relative to the narrow side surfaces 28. Subsequently, the upper cover layer 7, which can be rolled off endlessly from a further roll, is butted against the narrow side surfaces 28 of the spacer elements 18 by the inner cover surface 15a and connected to one another non-positively, in particular glued.

   The rolling movement of the upper cover layer 7 takes place by a drivable pressure roller or the adhesive connection between the upper cover layer 7 and the core layer 11, the controllable speed of the upper cover layer 7 to be unwound being slightly lower than the adjustable speed of the lower cover layer 7, so that a tensioning force during the Rolling of the upper cover layer 7 is effected by the further roll.



   After the application of the upper cover layer 7, the endless component 1 is fed to a pressing device, which is not shown any further and is arranged downstream in the transport direction - according to arrow 93 - and / or possibly a curing device for faster setting of the connecting and / or strengthening agent 70. The curing device can be formed, for example, by a high-frequency radiation generator, a temperature control chamber, etc., so that a faster curing process or the setting process of the connecting and / or strengthening means 70 can be carried out or shortened. Such pressing and curing devices are already general state of the art.

   After the component 1 has been pressed and / or the hardening and / or connecting means 70 may have hardened, the entire length of the endless component 1 is cut to a predeterminable format length. The core layer 11 has a length 97 that is shorter than the total length of the cover layer 7 that is wound up. Of course, the connecting and / or strengthening means 70 can also be applied to the connecting surfaces 16a; via an application nozzle under a pressure different from atmospheric pressure, in particular overpressure or underpressure. 16b are pressed or sucked in.



   As can also be seen, the spacer elements 18 are placed in the longitudinal direction of the unwound lower cover layer 7. Of course, as required in the application as a wall element, these can also extend transversely to the longitudinal extent of the unwound lower cover layer 7 or



  Direction of transport - aligned according to arrow 93 - be placed on the inner cover surface 15a.



   22 shows a schematic illustration for another manufacturing method of the self-supporting, load-bearing component 1 in a view and in a highly simplified schematic illustration. It should be pointed out that in this figure the component 1 has the lower and upper cover layers 7, between which the core layer 11 is composed of a plurality of spacer elements 18. Of course, this component 1 can also have only the lower cover layer 7 and the core layer 11, after which the method must be modified accordingly.

   The conveyor device 89 is formed by a plurality of sections 98 to 103 which are arranged directly one behind the other and which are each drivable, each of which is equipped with rollers 104 which rotate and drive axes which rotate and drive transversely to the transport direction - according to arrow 93 - and form a conveyor track Lower cover layers 7 cut to a predeterminable length 4 and width are moved in a clocked manner and each of the individual lower cover layers 7 is passed through partial sections 98 to 103 which are located one behind the other in the transport direction - according to arrow 93 - and are driven separately. A plurality of rollers 104 of a section 98 to 103 are preferably via a drive element, for. B.

   Chain, belt, drive-connected to each other and one of the rollers 104 is connected to a motor flanged to it

  <Desc / Clms Page number 26>

 driven, different work steps take place in the individual sections 98 to 103.



  In partial section 98, already formatted lower cover layers 7 are deposited on the rollers 104 forming the conveyor track by means of a corresponding handling system 105 and conveyed in the next partial section 99, clocked in the transport direction - according to arrow 93. In this section 99, the connecting and / or strengthening agent 70 is applied in a metered manner to the lower narrow side surface 28 of the spacer elements 18 and / or inner cover surface 15a of the lower cover layer 7 and further in the direction of transport - according to arrow 93 - via an application nozzle 106 - Subsequent section 100, the core layer 11 consisting of spacer elements 18 positioned over a handling system 107 and / or subsequently in a further section 101, if necessary, a filling of the cavities or

   Chambers are carried out with filler, whereupon in a further section 102 the connection and / or strengthening agent 70 is applied via the application nozzle 106 to the upper narrow side surface 28 of the spacer elements 18 and / or to the inner cover surface 15a of the upper cover layer 7 and then the upper cover layer 7 is fed to the next section 103, where the upper cover layer 7 is positioned on the core layer 11 via a handling system 108. The application nozzle 106 is designed to be adjustable in a sensor-guided manner at least in the direction parallel to the component plane, therefore in the longitudinal and width extension of the component 1, preferably along the longitudinal extension of the spacer elements 18. Before the core layer 11 is placed on the lower cover layer 7, these are precisely aligned beforehand.

   Likewise, the upper cover layer 7 is also aligned with the core layer 11 and the lower cover layer 7 before being placed on the core layer 11. At the end of the manufacturing process in a last section 109, the finished component 1 is fed to a further pressing process or postprocessing process via a handling system 110.



   As is no longer shown, the production system 89 according to FIGS. 21 or 22 can be immediately followed by a further system for carrying out further work processes, where, for example, post-processing, in particular surface treatment, for example on the outer cover surface 15b. B. grinding, painting, coating, surface hardening takes place. Of course, support elements, e.g. B. for roof tiles, and / or a protective film, for. B.



  Plastic film, bitumen film, attached to the component 1 or the component 1 can undergo chemical treatment, e.g. Insect repellent spray.



   As is no longer shown, there are of course 11 different variants of the production for the production of the core layer. For example, it is possible for a plurality of flat plate strips 77 forming the spacer elements 18 to be aligned directly next to one another in the form of a row and, before or after the core layer 11 has been placed on the inner cover surface 15a of the lower cover layer 7, initially adjacent flat surface layers intended for the spacer elements 18 Plate strips 77 in predeterminable connection areas 71 on adjacent broad side surfaces 23, 24 via the connection and / or strengthening means 70 at points or

   are connected linearly to one another, the connecting areas 71 between two plate strips 77 being arranged offset in the longitudinal direction thereof to the connecting areas 71 of the further plate strips 77 to be connected to one another and, before or after being placed between the connecting areas 71, plate strip parts located between the connecting areas 71 under the action of force to a lattice structure forming the core layer 11 pulled apart or expanded.



  Otherwise, it is also possible for a plurality of flat plate strips 77 to be arranged directly next to one another, in the form of a row and, under the action of force, to be pulled apart or widened to form a lattice path forming the core layer 11 and via the connecting and / or strengthening means 70 in Predeterminable connection areas 71 on broad side surfaces 23, 24 are connected to one another in a point-like or line-shaped manner, after which the core layer 11 with the spacer elements 18 via the connection and / or strengthening means 70 in predetermined connection areas 71 in a point-like or line-shaped manner with the inner one Cover surface 15a is initially connected to the lower and subsequently the upper cover layer 7.



   Of course, it is also possible that the spacer elements 18 already after their manufacture via appropriate devices, for. B. compression molding, get its final wave shape and the wavy preformed spacer elements 18 are placed on the inner cover surface 15a in the connection area 71 for the spacer elements 18, whereupon in predeterminable connection

  <Desc / Clms Page number 27>

 areas 71 on adjoining broad side surfaces 23, 24 of the spacer elements 18, these are connected to one another in a punctiform or linear manner. Before the spacer elements 18 are placed in the connection areas 71 for the spacer elements 18, the connection and / or strengthening agent 70 is applied between the latter and the inner cover surface 15a of the lower cover layer 7.

   A length of the connecting regions 71 between the spacer elements 18 and the cover layers 7 corresponds to the longitudinal extent of the spacer elements 18. Of course, the connecting and / or strengthening means 70 can also be applied directly to the inner cover surface 15a of the upper cover layer 7.



   Of course, it is also possible to place the spacer elements 18 and / or cover layer 7 made of wood material in predetermined connection areas 71 before applying the connection and / or strengthening agent 70 on the inner cover surfaces 15a and / or on the narrow side surfaces 28 facing away from one another and / or broad side surfaces 23, 24 on the one hand to enlarge the pores 74 and / or cavities 75 and on the other hand to at least slightly grind the flat support.



   It should also be pointed out that the spacer elements 18 and cover layers 7 are connected to one another in the connection areas 71 via the connection and / or strengthening means 70 and / or that the spacer elements 18 are connected at predetermined points 72 via connection elements, such as self-tapping screws or Brackets or nails etc. are optionally additionally connected to the cover layers 7. Furthermore, it is also possible for the spacer elements 18 to be positively and non-positively in their abutting turning areas 78, e.g. B. in the form of a in the vertical direction of the spacer 18 glued finger or tongue and groove connection.



   Finally, it should be pointed out once again that all features or combinations of features, such as those disclosed in FIGS. 1 to 15, can be transferred as disclosure points for the explanations explained in FIGS. 16 to 22.



   For the sake of order, it should finally be pointed out that, for better understanding of the component 1, this or its components have been partially shown to scale and / or enlarged and / or reduced.



   The task on which the independent inventive solutions are based can be found in the description.



   Above all, the individual in FIGS. 1, 2, 3, 4; 5, 6; 7.8, 9, 10, 11, 12; 13,14; 15, 16, 17; 18; 19; 20; 21 shown designs and measures form the subject of independent, inventive solutions.
