    Board for a composite element
    The invention relates to a board for a composite element formed by a plurality of identical boards, wherein the board along a longitudinal direction has a cross-section, which has at least one recess and a first projection and a second projection.
    Furthermore, the invention relates to a use of a composite element with at least one such board.
    Finally, the invention relates to a method for producing such
    Composite element.
    When manufacturing a building using wood, especially in the manufacture of wooden houses, usually boards and composite elements of the type mentioned are used to achieve a load capacity and tightness of the house. For this purpose, various boards, in particular wooden boards, composite elements comprising composite elements and such boards are known from the prior art. Wooden composite elements used to make a wooden house usually have boards connected by glue. Such a wood glue gives off even after completion of the house chemical ingredients that are partially harmful to health. This is considered a disadvantage in otherwise very ecologically and sustainably produced wooden houses.
    Although board door composite elements have become known from the prior art, which allow a glue-free connection of several identical boards. However, such boards or composite elements have further disadvantages.
    For example, EP 2 821 191 A1 discloses a wooden plate element which consists of at least two layers of parallel boards arranged side by side, wherein boards of two layers are connected to one another by dovetail connections. The dovetail connections are in this case along a longitudinal direction of a board by successive dovetail-shaped
    Recesses and projections formed, wherein recesses and projections are oriented transversely to the longitudinal direction.
    However, such dovetail connections have the disadvantage that one contact surface per dovetail connection is small and boards can be moved transversely to the longitudinal direction, ie along a shorter side, for which reason various embodiments are disclosed in this document in which additional means for fixing, such as pins and other fasteners are provided. In addition, a production of such a board is very expensive, since each board has a large number of milling edges.
    WO 2005/003489 A1 discloses plates which have a push-in plug-in profile, whereby in each case two plates can be connected next to one another. However, these plates do not allow a layered structure of a composite element formed therefrom, since such plates can only be connected side by side and not superimposed.
    There is therefore a need for simply constructed composite elements, in particular panels, which can assume supporting and / or sealing functions, in particular in the manufacture of a building, and can be formed free of adhesives, in particular free of glue.
    The object of the invention is therefore to provide a board of the type mentioned, which is easy to manufacture and at the same time a solid, positive connection of several boards to a multi-layer composite element, such as a panel or beam allows.
    Another object of the invention is to provide a use for a composite element formed from such boards.
    Finally, it is an object of the invention to provide a method of the type mentioned, with which a particularly simple composite element can be produced.
    The first object of the invention is achieved by a board of the type mentioned, which is designed such that the first projection of a first such board and the second projection of lying next to the first board second such board in the recess of a arranged on the adjacent boards third such board can be introduced, so that the first projection of the first board and the second projection of the second board are connected to the recess via at least one inner contact surface and the two adjacent boards via a common lateral contact surface, wherein the boards through the contact surfaces form-fitting manner with each other are connected.
    An advantage achieved with the invention is to be seen in particular in that with a corresponding board a composite element with high strength and tightness can be provided in a simple manner. A board according to the invention can for example be designed so that only one recess is provided on an upper side and / or lower side of the board, which is bounded for example by projections. As a result, a very low production cost is achieved because a single recess per side sufficient to ensure a stable connection. In addition, three or more identical boards can be connected together in two or more layers, since each board has on the one hand a recess into which the projections can engage, and on the other hand each board has projections which can thus engage in the recess of another board, that two such projections find space in a recess. Thus, two projections of two different boards are held together by the recess of a third board or the boards pressed together, resulting in a positive stabilization. Although a single recess per side is basically sufficient, of course, more recesses and projections may be provided.
    It is further advantageous that the board is designed such that a plurality of identical boards are positively connected, so that they are movable relative to each other only in the longitudinal direction. This ensures that the boards can indeed be pushed into each other to form the composite element, but in any other direction, ie up, down or to the side, are fixed, which is why the boards of a composite element thus formed stable together. Usually this is a
    Angle between the lateral contact surface and an inner contact surface less than 180 °, preferably between 20 ° and 90 °, preferably between 40 ° and 85 °, for example between 70 ° and 80 °. For example, the recess may be dovetail-shaped in a section perpendicular to the longitudinal direction or in a cross-section, so that a width of the recess increases with increasing depth, and the projections have corresponding cross-sections.
    Moreover, it is favorable if the at least one recess and the projections extend over an entire length of the board. As a result, on the one hand, two or more boards can be pushed into each other on the front side and, secondly, the connection over the entire length of the board is stabilized on both sides of the recess by the projections and fixed against movement transversely to the longitudinal direction.
    In order to allow the simplest possible design with few or as small as possible cavities in the resulting composite element, so that a dense, glue-free manufacturable composite element can be produced in a particularly simple manner, it is expedient if the first projection and the second projection arranged in an edge region of the board are, wherein the at least one recess is formed in a region between these projections.
    To ensure a firm and positive connection between a plurality of layers of corresponding boards arranged one above the other with simultaneously low production costs, it is expedient for the board to have at least two, in particular two or four, projections. Here, a board for a two-layer composite element on an upper side have two projections. For an at least three-layer connecting element, it is advantageous if boards have at least four projections, in each case two at the top or bottom, in order to allow a connection upwards and downwards. Due to a symmetry of an untreated board, it does not matter which side of the board is considered as the top or bottom.
    It may also be advantageous if the board is designed such that in an arrangement of several identical boards, wherein a arranged next to a first board second board with the first board is positively connected by a arranged on first board and second board third board, more Contact surfaces between the projections of the first board and / or the second board on the one hand and the recess of the third board on the other hand are provided. In particular, contact surfaces between two projections of different boards and / or further contact surfaces between one, two or more projections and the recess may be provided. For example, three interconnected boards may have, in addition to the inner contact surface and the lateral contact surface, another contact surface between the first protrusion of the first board and the second protrusion of the second board, with a plurality of boards gaining stability as the number of contact surfaces increases.
    To ensure additional stability, a bung may be provided on a first side surface and a groove on a second side surface of the board. It can also be provided several spits and corresponding grooves, which are distributed arbitrarily on the first and second side surface. It is important that there is a corresponding groove on the other side surface for each bung. It should be noted that a bung is not a projection in the sense of the above description. Protrusions are used herein to connect superimposed, partially overlapping boards, while the bung is intended to connect adjacent, flush boards. Alternatively, grooves may be provided on both side surfaces of the board and a spring for connection of two side by side boards.
    In a composite element with several boards, which is constructed in particular layered, it is advantageous if at least three boards are formed according to the invention, wherein a first board and a second board are arranged side by side and positively connected by a third board. Thus, an adhesive-free, in particular glue-free connection is made possible, with which at the same time a high strength and tightness can be achieved.
    It is also advantageous if, in such a composite element, the first projection of the first board and the second projection of the second board arranged next to the first board engage in the recess of the third board. By this intervention, a form fit is ensured in at least one spatial direction.
    Another advantage arises when the boards are fixed by an interaction of recesses and projections perpendicular to the longitudinal direction of the boards. Such a design ensures positive locking in a further spatial direction.
    A composite element with particularly good mechanical properties results when the first projection of the first board and the second projection of the second board substantially completely fill the recess of the third board.
    An easily produced positive connection with which the boards are positively fixed relative to each other in any direction except the longitudinal direction can be achieved, for example, by boards with an approximately dovetailed recess and projections which, when two boards side by side, substantially completely fill the dovetailed recess ,
    In addition, it may be beneficial if adjacent boards are connected via a tongue-and-groove connection. Alternatively, a tongue and groove connection can be provided between adjacent boards. As a result, a particularly dense composite element is achieved, which can also be used as a vapor barrier.
    In order to provide a composite element with a substantially smooth or even surface, it is expedient if, in the case of boards which close off the composite element on an upper side and / or lower side, at least one side without recesses and projections is formed. Thus, for example, in the case of a multilayer composite element, boards may be arranged on one outer side with projections and recesses and boards between the externally arranged boards with recesses and projections arranged on both upper and lower sides, wherein projections and recesses of all boards usually have approximately corresponding dimensions exhibit.
    It is also favorable if an overlapping width of the boards corresponds to about half the board width. As a result, for example, a recess arranged centrally in the board and thus the board be formed symmetrically. In addition, it is ensured that adjacent boards have a common contact surface. Alternatively, an asymmetric overlap may be provided. In order to ensure a tightness and a contact surface between adjacent boards, however, it is important that when connecting three boards, in which a first board next to a second board is arranged and first board with a second board by a third board arranged on these boards form-fitting the sum of the overlapping widths of the first board with the third board and the second board with the third board make up the entire board width of the third board. For this purpose, the overlap widths can correspond, for example, 1/3 and 2/3 of the board width.
    In order to ensure a firm and in particular glue-free or adhesive-free connection, it is advantageous if the boards are connected by means of press fit. The interference fit is particularly advantageous, since thus a material connection and accordingly hazardous vapors or other volatile substances which are contained in an adhesive, can be avoided and at the same time a dense composite element with high strength is achieved.
    A further advantage results in a building with at least one composite element, wherein the at least one composite element is provided as a wall panel, load-bearing element and / or vapor barrier. With sufficient thickness or a suitable coating, the composite element can also be used as a vapor barrier.
    The further object is achieved with the use of a composite element as a vapor barrier, wall panel and / or load-bearing element in and / or in a building. An advantage arises in particular from the fact that such a composite element has increased health and environmental compatibility.
    The procedural object is achieved in a method of the type mentioned, in which at least three boards according to the invention are provided, after which a first board and a second board are arranged side by side, after which a first projection of the first board and a second projection of the second board in a Recess of a third board are introduced so that the boards are positively fixed perpendicular to a longitudinal axis of the boards.
    It is also advantageous if the boards are made of dry lumber. In principle, any wood can be used for a composite element according to the invention, although it is favorable if the timber used has a bulk density of at least 500 kg / m 3 and / or a heat-vapor diffusion resistance of at least 10, in particular of at least 30. In addition, as a timber and multi-layer solid wood panels can be used. By using such a wood, the function of the composite element is ensured as a vapor barrier.
    It is also advantageous if the composite element is moistened and / or will. As a result, the wood used in volume gains. As a result of this increase in volume, the boards increase correspondingly, as a result of which a contact pressure of the projections in the recesses increases and thus connection points between the boards are solidified, so that a particularly firm and play-free connection or an interference fit is achieved, which in turn ensures a high degree of tightness of the composite element , The connection by means of a press fit is thus essentially unsolvable manually. On the one hand, moistening can take place actively, for example by steaming with steam, or passively by merely absorbing atmospheric moisture through the composite element.

    FIG. 8 is a composite element according to the invention designed as a beam. FIG.
    1a shows a front view of a board 1 perpendicular to a longitudinal direction of the board 1 with a central recess 2, a first projection 3 and a second projection 4. The recess 2 and the two projections 3,4, 11 are at an upper side of the board 1, so that the board 1 has a substantially C-shaped cross-section. Between the recess 2 and the first projection 3 and second projection 4, an inner contact surface 5 is provided, which in each case encloses an angle 7 with a lateral contact surface 6. In order to fix a connection upwards, it is advantageous if at least one angle 7 lies in a range between 0 ° and 180 °.
    Fig. 1b shows an analogous to the representation in Fig. 1a embodiment of the board 1, wherein two recesses 2 and four projections 3, 4, 11 are provided. Here, the recesses 2 and the first projections 3,4,11 and the second projections 3, 4, 11 respectively provided on the upper side and on an underside, so that the board 1 has a substantially H-shaped cross-section. As the top or bottom are here those pages to understand that correspond to the two longer sides in a cross section perpendicular to the longitudinal direction of the board 1. By virtue of this design, such a board 1 can be connected upwards and downwards, and thus a more than two-layered composite element 8 can be produced.
    An alternating sequence of a projection 3, 4, 11 and a recess 2 represents a profile which can be arranged on one side of a board 1, that is, only on the top, or on both sides, ie both on the top and on the bottom , A board 1 with such a one-sided profile on an upper side is shown in Fig. 1a and a board 1 with a two-sided profile both at the top and at the bottom is shown inter alia in Fig. 1b.
    Fig. 1c shows a two-layer composite element 8 comprising a plurality of identical boards 1 with a one-sided profile, in which in each case a first board 1 and a second board 1 are connected by a third board 1. Here, the first projection 3 of the first board 1 and the second projection 4 of the second board 1 fills the recess 2 of the third board 1 completely.
    Fig. 1d shows a four-layer composite element 8, wherein middle layers are formed by boards 1 with double-sided profile. The lowermost or uppermost layer is formed in each case by boards 1 with a one-sided profile in order to ensure a substantially flat closure upwards or downwards.
    Fig. 1e shows an exploded view of a three-layer embodiment of the composite element 8, the boards 1 are spaced in the vertical direction, that is perpendicular to the tops and bottoms of the boards 1 of the middle layer, in which tops and bottoms recesses 2 and projections 3,4, 11 are arranged.
    Fig. 2a shows a second embodiment of the board 1 with a single
    Recess 2, which is bounded by the first projection 3 and the second projection 4. In addition, this board 1 on the side contact surfaces 6 on the one hand a bung 9 and on the other hand a groove 10. By such a bung 9 and the groove 10, a lateral contact surface 6 is increased and a denser and more sustainable connection of several identical boards 1 allows.
    Fig. 2b shows a two-layer composite element 8, wherein a plurality of identical, one-sided profiled boards 1, which each have bung 9 and groove 10, are connected. Again, a first board 1 is in each case positively connected to a second board 1 arranged next to it by a third board 1 arranged on these boards 1, so that the boards 1 are fixed in a form-fitting manner in each direction, with the exception of the longitudinal direction of the boards 1.
    2c and 2d respectively show multilayer composite elements 8, wherein middle layers are formed by boards 1 with double-sided profile. It is thus a first one-sided profiled board 1 in a lowermost position with a next to this, identical second board 1 positively connected by a third board arranged on these 1, wherein the third board 1 is formed with two-sided profile.
    FIGS. 2e and 2f show a three-dimensional representation of a two-layer or three-layer composite element 8.
    Fig. 3a shows a board 1 with double-sided profile, wherein on the lateral contact surfaces 6 a bung 9 and a groove 10 are formed.
    Fig. 3b shows a multilayer structure of the composite element 8, wherein the middle layers are formed by boards 1 with double-sided profile and the outer layers, which bound the composite element 8 in Fig. 3b above and below, by boards 1 with a one-sided profile. In addition, each adjacent boards 1 are connected by a bung-groove connection.
    3c shows a three-dimensional representation of such a composite element 8.
    Fig. 4a shows another embodiment of a board 1, wherein two recesses 2, the first and the second projection 4 and a further projection 11 are provided. The recesses 2 and projections 3,4,11 are arranged on the upper side of the board 1. In such an embodiment, the recesses 2 are limited by the first projection 3 and the further projection 11 or by the further projection 11 and the second projection 4. The first projection 3 and the second projection 4 are, as in all other embodiments, arranged in an edge region of the board 1.
    Such a board 1 has four recesses 2 and six projections 3,4,11, wherein two recesses 2 and three projections 3,4,11 at a top or bottom are positioned.
    4c to 4e each show a two-, three- and four-layered construction of such a composite element 8.
    Fig. 5a shows a further embodiment of the board 1 with a single
    Recess 2. Here, the first projection 3 and the second projection 4 are arranged at a distance from the lateral contact surfaces 6 of the board 1.
    Fig. 5b shows the variant with double-sided profile of the board shown in Fig. 5a 1. Here, the recess 2 and the first and the second projection 4 in turn twice, at each of the top and bottom, provided.
    FIGS. 5c to 5e each show a two-, three- or four-layered embodiment of the composite element 8. By spacing the projections 3, 4, 11 from the lateral contact surfaces 6, cavities 12 are created in the composite element 8, which serve to reduce the weight of the composite element 8 can. Alternatively, the cavities 12 may be filled with a filling material, for example for thermal insulation. As can be seen, it is thus not absolutely necessary to achieve a firm and tight connection of several identical, inventively designed composite elements 8, that the projections 3, 4, 11 completely fill the recess 2, although this is preferred.
    In contrast to other embodiments, the inner contact surfaces 5 are parallel to each other, but, as in other embodiments, aligned against the lateral contact surfaces 6 inclined. In order to ensure a sufficient fixation, it is usually provided that an angle 7 between at least one of the two inner contact surfaces 5 and the lateral contact surface 6 is less than 180 °. In this definition, the angle 7, starting from the inner contact surface 5 following a circular line, is to be measured by the board 1, as indicated in FIGS. 1 a and 6 a. In the board 1 shown in Fig. 6a thus the angle 7 between the inner contact surface 5 on the first projection 3 and the lateral contact surface 6 is more than 180 °, but the angle 7 between the inner contact surface 5 on the second projection 4 and the lateral contact surface 6 less than 180 °, so that even with parallel inner contact surfaces 5 a stable and tight connection can be achieved.
    6c and 6d each show a two-layer or three-layer structure of a composite element 8 from such boards 1.
    Fig. 7a shows the nesting of several boards 1. Here, the first and the second board 1 are placed next to each other, after which the first projection 3 of the first
    Board 1 and the second projection 4 of the second board 1 are inserted into the recess 2 of the third board 1. As a result, the third board 1 relative to the first board 1 and the second board 1 in the arrow direction moves translationally, for example, moved or pulled until end-side board ends of the first board 1, the second board 1 and the third board 1 complete each other.
    Fig. 7b shows an alternative method in which the first and second boards 1 are moved relative to the third board 1.
    The boards 1 for such composite elements 8 may also be formed with any number of projections 3, 4, 11 and recesses 2, wherein features of all embodiments shown can be combined with each other as desired.
    Such formed composite elements 8 may be formed arbitrarily large area, since a width of such a composite element 8 is determined only by the number of adjacent boards 1 and their width. Furthermore, such a composite element 8 can be formed almost arbitrarily thick, since a thickness of such a composite element 8 is determined only by the number of layers and their thickness. For an application of a composite element 8 in the manufacture of a building, a length of the composite elements 8, for example, about 2 m and a width of the composite elements 8, for example, about 60 cm. A board 1 used for such a composite element 8 can then have a width of about 12 cm and a height of about 3 cm. Such composite elements 8 may be formed as a beam, panel or the like, depending on their field of use.
    Fig. 8 shows an example of such, designed as a supporting beam composite element. As shown, the composite element, in addition to boards according to the invention, of course, also have other elements, such as end edge boards here, in order to achieve a smooth termination of the support on lateral surfaces.
    Such composite elements 8 are particularly preferably used in house construction as a wall panel, paneling, beams or vapor barrier. However, the field of application is not limited to these examples.
    With a board 1 designed according to the invention and a composite element 8 or panels formed from several such boards 1, a building such as a wooden house can be produced in a simple manner without the use of glue or the like. The composite elements 8 designed according to the invention can be used as load-bearing elements or as a vapor barrier. Thus, a sustainable and at the same time cost-effective production of a wooden house is made possible. Since no glue or the like must be used, the composite elements 8 can be disposed of after use in a simple manner, for example by burning, without thereby polluting substances are released. It is thus when using a board according to the invention 1 and an inventive
    Composite element 8 achieved a completely ecological and cost-effective design.
