Abstract

A construction element 1 consists of multiple individual layers 2, 3, 4 whereas the medium layer 3 is in turn composed of a multitude of additional individual layers 23, 24, 25 . The individual layers 2, 4, 23, 24, 25 are configured in such a way that they interlock and clamp into each other thereby producing or defining surfaces that allow the elements or individual layers 2, 4, 23, 24, 25 that are integrated in the construction of the construction element to evenly absorb the forces that are being applied. At the same time, not only pressure or lateral forces but also tensile and transverse forces can be absorbed so that altogether a construction element 1 with a low weight but high stability has been created. This construction element 1 can be shaped or deformed appropriately and can also be extended three-dimensionally so that an adaptation to the individual conditions in any plane or direction is possible.

Description

The invention relates to a component composed of several individual layers which is a honeycomb construction with protruding beyond the basic construction Have partial hollow bodies, wherein the individual layers can be joined together with the partial hollow bodies are.

Components in the form of material plates are known, both the Honeycomb construction as well as the two cover plates made of paper or cardboard are. The honeycomb construction, similar to that of honeycombs, is supported by its approximately vertical partition walls on the cover plates, so that plates result with increased stability and advantageously low weight. From the corresponding Material panels can be used to manufacture doors, for example. But you will also used in interior construction and trade fair construction (DE-OS 197 48 192.2). adversely is that the overall construction can be affected by moisture. Problematic is also the design of the border area with the corresponding Edge reinforcement, because this is separate from the other parts of the known here Material plate must be connected. DE-OS 19 22 693.8 is a method and a component is known that is also sandwiched. The two Cover plates made of metal and the interposed cell walls or the corresponding Honeycomb structures are connected to the cover plates by welding or soldering, wherein in particular the soldering material is guided so that it can also be found in the Cell corners are fixed and so the cover plate is particularly good with the honeycomb construction combines. Despite the strengthening of the cell corners, it essentially remains that the approximately vertical cell walls are on the two cover plates support and thus have to transfer the forces to be taken over. Accordingly With such lightweight honeycomb structures, the stability is almost entirely from depending on the top layers. The inherent stability of the sandwich core, however, is negligible small. Another disadvantage is the relatively complex production method, as well the use of different materials and the impossibility, for example also use plastic. From GB 956 132 A a component is known that is composed of several egg-box-like individual layers. The individual layers have hollow bodies of different dimensions in order to assemble Marginal zones with an increased number of hollow bodies and slightly flat contact to reach. The middle individual layers have no flat support or connection with each other, just a linear connection. High pressures and torsional Burdens cannot be accepted and transferred.

The invention is therefore based on the object of minimizing a component To create weight and with favorable stability and insulating properties.

The object is achieved according to the invention in that the embossed with the adjacent individual layers in the flat connection, if possible, a wall single layers as a very thin wall Partial honeycomb panel or partial honeycomb film are formed over a basic construction and positive and / or negative hollow bodies or partial hollow bodies protruding above them have a first individual layer, which serves as a coupling element for the individual layers half of the hollow body is provided with a second single layer Equipped holes and thus to claw and connect with the first individual layer is that the missing sides are formed by complementary partial hollow bodies and that a third individual layer has partial hollow bodies, which in that of the first and second Single layer formed part hollow body is insertable, so that the surfaces of all one enter into a flat connection.

Deviating from the prior art, all elements here take the same thing Part of the force absorption and force distribution, so that the peculiarity or Stability of the top layers is no longer important. Rather, the entire component carries consistently uniform, so that it is possible to have both vertical and horizontal as well as producing and closing inclined walls and components realize. Take regardless of the respective arrangement of the component all individual layers or better said individual layer parts on the force absorption and force transmission and ensure that a total of one component is available, that with extremely low weight, high stability values and more provides optimal sound and temperature insulation. The latter mainly because that the individual individual layers have either hollow bodies or partial hollow bodies or form such together, the air contained in the hollow bodies being the most optimal Insulator acts against both temperature and sound. Another advantage is that such a component can not only take on vertical loads, but also shear forces or other loads deviating from the rule without it this requires an increase in wall thickness or other measures. The corresponding Hollow bodies or partial hollow bodies can also be used to Absorb liquid or inert material and, for example, fire resistance to provide, which makes the use possible even in extreme situations. The individual component is made from individual nested individual layers, whereby this gives the possibility of specifying a construction that once due to the extensive training and on the other hand due to the corresponding Shaping to create wall thicknesses of practically any thickness or with corresponding ones mutually touching hollow bodies, the ones described above Bring advantages. The low weight of such is particularly impressive Components and the high stability that u. a. also through the flat connection achieved and support and formation of stable walls is achieved. The first, the second and third individual layers are created by clawing and joining together to a honeycomb construction with a surprising multiple effect.

A corresponding construction of such a component is in particular due to this achieved that the hollow body or partial hollow body assigned to the individual layers with the hollow bodies or partial hollow bodies of others which represent the middle individual layer Individual layers and these again having corresponding surfaces are trained. The corresponding partial hollow bodies or hollow bodies become corresponding Hollow bodies or even closed hollow bodies if the corresponding Individual layers, as mentioned above, are nested or nested become. The separately produced individual layers, on their separate structure will be discussed later, are coordinated so that they in each case specify the partial hollow bodies or hollow bodies described and assign them to one another also form accordingly. The individual layers or the partial hollow bodies and hollow bodies have a very small wall thickness, with further details above It has been pointed out that they are designed, for example, as a partial honeycomb film can. These individual thin-walled honeycomb panels are complemented by combined with each other when nesting or nesting and also added so that the surfaces of the individual partial hollow bodies lie against each other or hollow body results in the favorable transmission of the forces and on the other hand also an additional stabilization of the entire component structure.

It has turned out to be particularly useful that the individual layers assigned hollow body or partial hollow body with those of other individual layers when Interleaved to result in a pyramid or mirror image double pyramid are. This pyramid shape has the advantage that four or more surfaces are used Are available to the neighboring pyramid or the hollow body or partial hollow body can be created and adjusted in order to ensure the flat transmission of the Ensure forces. The pyramid can be standing, lying or otherwise formed be or only arise when the individual layers are joined together without thereby fear of a reduction in the stability of the entire component would.

Expediently, the individual layers are made of partial hollow bodies or Hollow bodies formed pyramids arranged and formed so that adjacent, pyramids or mirror image double pyramids also formed when nesting lie flat against it, with a flat connection of the individual layers static cross wall is created, which absorbs the forces from all sides is. Here it is additionally pointed out that the pyramid shape is particularly well suited to a flat "connection" of the individual pyramid parts to ensure each other. The areas of the individual pyramids are all used for Creation of adjacent pyramids of the same or different individual layers, so that it follows from the description that this results in an optimized construction is created that the characteristics of the low weight and high stability. The result is an advantageous one Cross wall that can absorb forces from all sides.

In the normal case, it is advantageous if five individual layers form a combination element resultant are put together, with a middle and a positive and negative Partial hollow body has the first individual layer, which has an intermediate single-cell layer on both sides and then assigned a single layer provided with partial hollow bodies on one side is. The individual layers are taken as described in the description can, put together or nested, so that an overall stabilized Component results in that the pyramid surfaces are particularly advantageous Forwarding or derivation of the occurring forces ensures. Different from the Sandwich components that have been common up to now are here, in some respects, as cover plates significant outer individual layers also integrated into the stability structure by they also on their underside with corresponding hollow bodies or partial hollow bodies are equipped with the one between the individual layer and the middle class Design that guarantees the desired stability properties. by virtue of the hollow bodies or partial hollow bodies assigned to the “cover layers” can also Shear forces or other unusual forces are easily absorbed because these forces from the "cover layers" into the intermediate layer or intermediate individual layer initiated that a safe removal or forwarding is possible. Since the "cover layers" do not have a stability task or at least no separate task or the sole task of stability, it is possible that the entire combination element also curved or otherwise curved, because these individual layers on the edge are made of the same thin-walled material as the interposed ones Individual layers.

A honeycomb structure that can be expanded into the room, or rather a hollow body structure can be realized in that one or both intermediate single layers have one Single adapter layer or the subsequent first single layer on both sides adapter single layers Building of any height and / or width resulting from the spatial construction assigned. The individual adapter layers make it possible, so to speak, on the middle layer building up again to build a corresponding construction so that in the room the component has to be cleverly and specifically expanded. Here too is one homogeneous power transmission secured so that no matter where a force acts, this force is evenly distributed to all elements, with this combination the possibility is created to build up any total wall thickness.

This further expands the component into the room possible that the adapter single layer alternately positive partial hollow body or hollow body and has recesses. For example, a middle class can work together with adapater single cell layers arranged on both sides on one side "Single layer" acting like an edge-side single layer or correspondingly be constructed, whereby the corresponding complementary structure into the room is achieved.

The strength of the component structure can according to the invention by the The choice of material can be varied, the invention providing that the individual layers made of paper soaked in liquid plastic, aluminum, steel or consist of plastic films. The corresponding individual layers show thereby, as already mentioned above, a wall thickness in the µ range, whereby this in the invention is clarified further above by the term "film". Depending on the application components can do exactly the right purpose be created, both in terms of price and stability values Possibility to provide optimal components. It is it is also conceivable that the individual layers are made from woven, preferably from plastic threads or fiber composite materials woven foils, so the strength properties and thus the stability values even further targeted to the respective operating conditions to be able to adapt.

The corresponding hollow body or partial hollow body should according to the Support the invention optimally flat against each other, the intermediate areas between contribute to the pyramids, as explained later. This stable However, individual layers can nevertheless be bent into the respective shape according to the invention or be edged, since according to the invention those leading up to the top of the pyramid Edges are perforated and / or slotted. With a corresponding load this perforation or the slitting is not problematic, because nevertheless the areas are contiguous and the corresponding forwarding or recording of Secure forces. Perforating or slitting also allows bending in the area of the individual pyramid without causing a deformation of the pyramid or of the corresponding hollow body must come.

Another expedient design provides that the honeycomb structure resulting hollow body with inclined surfaces, preferably on a Edge are arranged at an angle. This sloping arrangement of the surfaces is optimal because the entire hollow body is then included in the line of force can, without there being differently loaded or unloaded sections of the hollow body gives. The oblique surfaces of the hollow bodies lie against one another and pass on the impact force or ensure an optimal distribution and thus Utilization of the entire honeycomb structure and ultimately also the corresponding one Component.

The edge-side individual layers act or serve in the component according to the invention no more than top layer. Rather, they are in the entire component integrated by their hollow body or partial hollow body. Still, an exterior is smooth Formation possible in that the edge-side individual layers on the inside hollow body or partial hollow body and have a flat cover on the outside. The flat cover enables the corresponding components to be stacked, but then there is no interlocking of the components. Are advantageous such trained components in particular, for example, in the manufacture of Partitions or the like.

The individual layers on the edge also consist of the same material with the same wall thickness as the other individual layers, so that the edge-side individual layers fully participate in the movements or better in the shapes of the other individual layers. This can be supported by the fact that the upper and the lower Single layer are made of flexible material or material to be made flexible. For example, it is conceivable here that a softer one for the individual layers on the edge Plastic is used as for the other individual layers.

If the respective component is brought into the intended shape, it can be useful be to connect the individual layers with each other, this in particular is achieved in that the hollow body or the partial hollow body, the honeycomb structure resulting permanent with each other taking into account the material property or also releasably connected, preferably welded, glued, screwed together or are connected by friction. As can be seen from this wording is, the respective shape can also be produced by this connection and thereby then be made the same.

The appropriate pyramid shape for the individual hollow bodies or partial hollow bodies has already been received. In addition, the invention provides that the Partial hollow body or hollow body of the individual layer pyramid-shaped and the honeycomb construction forming hollow pyramid-shaped or a mirror image double pyramid are trained accordingly. These double pyramids or rather Mirror image double pyramids support each other over the lower edges and thus form a stable spatial structure that fulfills the described and required tasks optimally sufficient. Here is also a gluing, screwing, etc. possible to to effectively connect the pyramids or double pyramids with each other and with each other to couple.

The high stability of such components is due to the flat support of the elements involved in the honeycomb construction, with the Edges or clashing components of the basic construction are included can be by the pyramidal partial hollow body or the hollow body the base construction are spaced apart to form a spacer while the segments the double pyramid-shaped hollow body parallel to the central axis running edge strips are interconnected. So that is also in this Areas ensured a flat support instead of the previously usual linear Support.

The stability of the entire component is thus specifically increased. The joining together of the individual segments of the double pyramid-shaped hollow body or the partial honeycomb panels and the secure flat support is favored in that the tips of the segments of the double pyramid-shaped hollow body or the partial hollow body are flattened. This is a threading of the honeycomb panels favors and facilitates merging.

A precise support of the pyramid tips in addition to the one on top of the other Areas of the cooperating pyramids or mirror image double pyramids can be achieved according to the invention in that the flattening at the top the pyramid or the mirror image double pyramid with the spacer strip and / or Edge strips corresponding and designed to ensure a flat support is. The tip is also integrated into the flat support structure by the Flattening - as described - is done specifically, so that the Pyramids or mirror image double pyramids exactly in or on the spacer strips or have the edge strips fitted.

An advantageous balance of forces or a flexible component arises if the hollow body or the surfaces of the individual layers together by means of an elastic mass are connected to form a wall. Depending on the thickness and type of elastic The individual layers or the hollow bodies can "move" without loss of stability. This training is particularly advantageous when there are only a few individual layers formed hollow body contour honeycomb. Blows can also be recorded, yourself the impact of a stone is springed up.

For insulation, fire retardancy and other reasons, it can be useful be the hollow body after connecting with a gaseous or liquid medium to fill completely or partially, with an exchange between the individual hollow bodies is achieved via recesses left in the walls. The kind of "Filling" depends on the application.

Further training is advantageous, in which the so-called neutral Fibers with the flat connections connected to the next neutral fiber and the intermediate layers represent the intermediate spaces, the surfaces of which also get a connection.

The invention is characterized in particular by the fact that all of the structure such a honeycomb structure elements involved in the inclusion on the Involve component forces. That means the forces from the outside Level and added to the subsequent elements, d. H. the individual layers and their individual parts are forwarded. So the individual elements are one such component jointly responsible for the stability of the entire component. The top layers or individual layers on the edge no longer need anything special to be constructed in terms of stability, but have the same wall thickness as that remaining individual layers and usually consist of the same material. Not only are they simpler in terms of their structure, they also hinder them the shape of the entire component is no longer, since it with the intermediate individual layers bent together or otherwise deformed to the component to give the desired shape. They are also from the "internal structure" Individual layers are predefined in such a way that the overall component is shaped accordingly is possible. The individual hollow bodies or partial hollow bodies are on the edges, that lead to the top of the pyramid, cut open or otherwise weakened, so that they are the do not conflict with the corresponding shape. It is particularly advantageous that with With the help of the corresponding individual layers of components of practically any wall thickness can be manufactured, but with an extremely low overall weight. In addition, it is possible not only the entire wall thickness of such components adapt to the respective conditions, but also their extension in the plane, because the individual layers are interlocked, arranged and assembled in this way can that it is practically possible without transitions, correspondingly large components to realize. This creates and is possible for a room construction that with no other component is even conceivable. Finally, is from further The advantage that it is possible with such components, even a wide variety of materials to adapt to different tasks enable.

Figure 1 shows a component 1 in the finished state. The upper edge single layer 2 is partially open to reveal the honeycomb structure 3 that once on the upper edge-side individual layer 2 and on the other at the lower edge layer 4 supports. The honeycomb structure 3 is shown here in simplified form. As explained further below, the individual layers 2, 4 are integrally formed.

The side edge 5 of the component 1 is a smooth plane here shown, as well as the edge-side individual layer 2, which is achieved there is that a cover on the single layer 2 shown further back 29 is applied.

The honeycomb structure 3 consists of a large number of individual layers 23, 24, 25 with hollow bodies 7, 8, 9 or partial hollow bodies 26, 27; the corresponding reference numerals can be found in the following figures.

Both the edge-side individual layer 2 and the edge-side individual layer 4 and the intervening honeycomb structure 3 with the corresponding individual layers 23, 24, 25 consists of honeycomb panels 17 of small wall thickness. This honeycomb panel 17 is usually even designed as a partial honeycomb film, ie it has a wall thickness in the μ range on.

The honeycomb structure 3 or the individual layers 2, 4, 23, 24, 25 are with hollow bodies 7, 8, 9 according to FIGS. 2 and 3 or partial hollow bodies 26, 27 according to FIG 6 trained. For the sake of simplicity, it is not clear between the following Hollow bodies 7, 8, 9 and partial hollow bodies 26, 27 differentiated because when joining the individual layers 2, 4, 23, 24, 25 are in turn hollow bodies 7, 8, 9 like also form part hollow bodies 26, 27, the total of the honeycomb structure 3 and Guide component 1.

The individual hollow bodies 7, 8, 9 according to FIG. 2 and FIG. 3 generally form Pyramids 14, 14 'or mirror image double pyramids 19, with the individual segments 20, 21 serve to support the individual elements as a whole the honeycomb structure to reach each other and ensure. Like the figures 2 and 3 and the other figures, the pyramids are suitable 14 or mirror image double pyramids 19 are particularly favorable for such a flat area Support of the individual elements, because surfaces 10, 11 are offset accordingly are available that are also large enough to correspond to the component 1 acting forces can be safely absorbed and forwarded.

The mirror image double pyramid 19 consists of the two pyramids 14, 14 ' are connected to one another via a coupling web 22. The central axis 30 separates the two Elements or along this central axis are connected to one another.

Flattenings 13 are provided at the tips 12 of the individual pyramids 14, 14 ', an additional favorable support for the individual parts or individual elements towards the edge strip 31 or the spacer strip 18 or the base construction 16 enable.

While the "dividing line" in Figure 2, the two pyramids 14, 14 'into one Double pyramids 19 assembles, according to Figure 3 is the center axis 30 at the same time the dividing line that leads through the flattened tips 12. Not visible is that the edges 15, 15 'are perforated or cut open can so as to bend or bend the corresponding individual layer and also to enable the entire component 1 without excessive forces being used Need to become.

FIG. 4 shows an individual layer 2 or 4 on the edge, which is on the inside 28 Has hollow bodies 7, 8 or pyramids 14. These individual pyramids 14 are all same mast and connected to each other via the basic construction 16. This basic construction 16 simultaneously forms the spacer strips 18, which ensure that once the individual pyramids 14 are arranged at the same distance from each other are and at the same time ensure that when pushing the individual Individual layers 2, 4, 23, 24, 25 resulting partial hollow bodies 26, 27 and 7, 8, 9 also can support with their tips 12 on this spacer strip 18. The stability the corresponding overall construction of the component is thereby optimized.

By using the same reference numeral 18 for everyone between the Pyramid 14 basic structures 16 make it clear that they are all should have the same dimensions. They are provided with 18 'and 18 ".

Figure 5 corresponds in principle to the representation of Figure 4 only that here Perspective is reproduced, which at the same time makes it clear that the corresponding Surfaces 10, 10 ', 11, 11' all on the mutual support and thus on the forwarding of the occurring or impacting forces are involved. The corresponding here also pyramids 14 formed on the inside 28 have the same shape on and thus also the same surfaces 10, 11. Between the individual pyramids 14 the base construction 16 or the spacer strips 18 run.

FIG. 6 shows a component 1, which here consists of a total of five individual layers 2, 4, 23, 24, 25 is composed. The marginal individual layers are designated with 2 and 4, while the middle layer 25 or the middle individual layer 25 with their protruding on both sides Partial bodies 26 and 27 simultaneously as a coupling element for the individual layers 23, 24 and then the edge-side individual layers 2, 4 is used. It can be seen that the so-called Middle class, d. H. thus the middle individual layer 25 protruding on both sides Has pyramids 14 or 14 'available for clawing or connection with to enable and favor the appropriately trained individual layers 23 and 24, complementary hollow bodies 7, 8, 9 or partial hollow bodies 26, 27 arise.

The component 1 shown in FIG. 6 is in FIG. 7 shortly before the assembly reproduced, which is also intended to indicate optically that the edge-side individual layers 2, 4 and the individual layers 23, 24, 25 are so nested and can be nested in one another so that it forms a flat component high stability and low weight, with another advantage being the isolating effect of such a component results.

Figure 8 finally shows the component of Figure 6 and Figure 7 in perspective Representation also shortly before the assembly, whereby it becomes clear here that the edge-side individual layers 2, 4 have no cover here.

FIG. 9 finally shows a component 1 that consists of a total of eleven individual layers 2, 4, 23, 24, 25, 25 'and 33, the individual layers 23 and 24 and 25' and 33 are duplicated. The individual layers 2, 4 and also the individual layers 23, 24, 25 are known from the preceding figures, with two individual adapter layers here 33 come from the middle single layer 25 with hollow bodies on both sides 7, 8, 9 make a single layer 2 or 4 on the edge, because they alternate with Pyramids 14 and recesses 34 are provided and thereby on both sides of the middle individual layer 25 result in a coupling surface that those of the inside 28 of the edge-side individual layer 2 or 4 correspond. This is an extension of a corresponding one Component according to Figure 6, 7, 8 possible in the room, so that Components 1 of virtually any wall thickness can be generated.

The individual figures also show that the special training the individual layers 2, 4, 23, 24, 25 and also 33 give the opportunity by accordingly staggered arrangement of the individual layers 2, 4, 23, 24, 25, 33 a To bring about expansion in the plane that the expansion of the component 1 to a very large component.

17. Construction element according to any of the preceding claims, characterised in that the apexes (12) of the segments (20, 21) of the double pyramidal hollow bodies (7, 8, 9) and of the partial hollow bodies (26, 27) are flattened.
18. Construction element according to any of the preceding claims, characterised in that the flattening (13) at the apex (12) of the pyramid (14) or of the mirror-inverted double pyramid (19) is constructed so as to correspond with the spacing strip (18) and/or the edge strip (31) and so as to guarantee a plane support.
19. Construction element according to any of the preceding claims, characterised in that the hollow bodies (7, 8, 9) and the faces of the individual layers (2, 4, 23, 24, 25, 33) are connected by means of an elastic mass so as to jointly form a wall.
20. Construction element according to any of the preceding claims, characterised in that the hollow bodies (7, 8, 9) are completely or partially filled after joining with a gaseous or liquid medium.
21. Construction element according to any of the preceding claims, characterised in that the individual layers (2, 4, 23, 24, 25, 33) have recesses in the walls and/or the spacing strips (18) which after nesting and connection are used for through-flowing or circulating guiding of gas or liquid.
22. Construction element according to any of the preceding claims, characterised in that the so-called neutral fibres are connected with the plane connections to the next neutral fibre and the intermediate layers provide the intermediate spaces, the faces thereof also having a connection.
