Definitions

  • the invention relates to a board for a composite element formed by several identical boards, the board having a cross section along a longitudinal direction which has at least one recess and a first projection and a second projection.
  • the invention further relates to the use of a composite element with at least one board of this type.
  • the invention relates to a method for producing such a composite element.
  • Boards for composite elements have also 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.
  • the EP 2 821 191 A1 a panel element made of wood, which consists of at least two layers of parallel boards arranged side by side, boards of two layers being connected to one another by dovetail joints.
  • the dovetail joints are here along a longitudinal direction of a board by successive dovetail-shaped Recesses and projections are formed, with recesses and projections being oriented transversely to the longitudinal direction.
  • dovetail joints designed in this way have the disadvantage that a contact surface per dovetail joint is small and boards can be moved transversely to the longitudinal direction, i.e. along a shorter side, which is why various embodiments are disclosed in this document, in which additional means for fixing, such as pins and other connecting elements are provided.
  • additional means for fixing such as pins and other connecting elements are provided.
  • production of such a board is very expensive since each board has a large number of milled edges.
  • the WO 2005/003489 A1 discloses panels which have a slide-in plug-in profile, whereby two panels can be connected side by side.
  • these panels do not allow a layered structure of a composite element formed from them, since such panels can only be connected next to one another and not one on top of the other.
  • the object of the invention is therefore to provide a board of the type mentioned at the outset that is easy to produce and at the same time enables a firm, form-fitting connection of several boards to form a multi-layer composite element, such as a panel or beam.
  • a further object of the invention is to indicate a use for a composite element formed from such boards.
  • the first object of the invention is achieved by a board of the type mentioned at the beginning, which is designed in such a way that the first projection of a first such board and the second projection of a second such board lying next to the first board fit into the recess of one 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 are connected via a common lateral contact surface, the boards being positively connected to one another through the contact surfaces are connected.
  • a board according to the invention can, for example, be designed in such a way that only one recess is provided on an upper side and/or underside of the board, which recess is delimited, for example, by projections. This results in very low production costs, since a single recess per side is sufficient to ensure a stable connection.
  • three or more identical boards can be connected to one another in two or more layers, since on the one hand each board has a recess into which the projections can engage, and on the other hand each board has projections which can engage in the recess of another board that two such projections can be accommodated in a recess.
  • two projections of two different boards are held together by the recess of a third board or the boards are pressed together, resulting in form-fitting stabilization.
  • a single recess per side is sufficient in principle, further recesses and projections can of course be provided.
  • the board is designed in such a way that several identical boards can be connected in a form-fitting manner, so that they can only be moved relative to one another in the longitudinal direction. This ensures that the boards can be pushed into one another to form the composite element, but are fixed in any other direction, i.e. up, down or to the side, which is why the boards of a composite element formed in this way hold together stably.
  • This is usually one Angle between the lateral contact surface and an inner contact surface is less than 180°, preferably between 20° and 90°, preferably between 40° and 85°, for example between 70° and 80°.
  • the recess can be dovetail-shaped in a section perpendicular to the longitudinal direction or in a cross section, so that the width of the recess increases with increasing depth, and the projections have corresponding cross sections.
  • the at least one recess and the projections extend over the entire length of the board.
  • two or more boards can be pushed into one another at the front and, on the other hand, the connection over the entire length of the board on both sides of the recess is stabilized by the projections and fixed against movement transverse to the longitudinal direction.
  • first projection and the second projection are arranged in an edge region of the board are, wherein the at least one recess is formed in a region between these projections.
  • the board has at least two, in particular two or four, projections.
  • a board for a two-layer composite element can have two projections on an upper side.
  • boards have at least four projections, two each on the top and bottom, in order to enable a connection upwards and downwards. Due to the symmetry of an untreated board, it is irrelevant which side of the board is considered the top or bottom.
  • the board is designed in such a way that when several identical boards are arranged, a second board arranged next to a first board being connected to the first board by a first board and a second board arranged third board is positively connected, further contact surfaces are provided 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.
  • contact surfaces can be provided between two projections of different boards and/or further contact surfaces between one, two or more projections and the recess.
  • Three interconnected boards can, for example, have a further contact surface between the first projection of the first board and the second projection of the second board in addition to the inner contact surface and the lateral contact surface, with a connection of several boards gaining stability with an increasing number of contact surfaces.
  • a bung can be provided on a first side surface and a groove on a second side surface of the board.
  • Several bungs and corresponding grooves can also be provided, which are distributed as desired on the first and second side surfaces. It is important here that there is a corresponding groove on the other side surface for each bung.
  • a bung does not represent a projection in the sense of the above description. Projections are used herein to connect superimposed, partially overlapping boards, while the bung is intended to connect adjacent, aligned boards.
  • grooves can be provided on both side surfaces of the board and a tongue can be provided for connecting two adjacent boards.
  • 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. This intervention ensures a positive fit in at least one spatial direction.
  • a further advantage arises when the boards are fixed perpendicularly to the longitudinal direction of the boards by an interaction of recesses and projections. Such a design ensures a form fit 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 essentially completely fill the recess of the third board.
  • a form-fitting connection that is easy to produce, with which the boards are fixed in a form-fitting manner relative to one another in every direction with the exception of the longitudinal direction, can be achieved, for example, by means of boards with an approximately dovetail-shaped recess and projections, which essentially completely fill the dovetail-shaped recess when two boards are arranged side by side .
  • a tongue and groove connection can be provided between adjacent boards. This results in a particularly dense composite element, which can also be used as a vapor barrier.
  • boards which close off the composite element on an upper side and/or underside at least one side is designed without recesses and projections.
  • boards can be arranged on an outer side with projections and recesses only on one side and between the boards arranged on the outside boards with recesses and projections arranged both on the top and on the underside, with projections and recesses of all boards usually having approximately corresponding dimensions exhibit.
  • an overlapping width of the boards corresponds to about half a board width. This allows, for example, a recess in the middle of the board arranged and thus the board can be designed symmetrically. In addition, it is ensured that adjacent boards have a common contact surface. Alternatively, an asymmetrical overlap can be provided. However, in order to ensure tightness and a contact surface between adjacent boards, it is important that when three boards are connected, in which a first board is arranged next to a second board and the first board with the second board is positively connected by a third board arranged on these boards are connected, the sum of the overlapping widths of the first board with the third board and of the second board with the third board result in the total board width of the third board. For this purpose, the overlap widths, for example, 1 ⁇ 3 and 2 3 correspond to the width of the board.
  • the boards are connected by means of a press fit.
  • the press fit is particularly advantageous since a material connection and correspondingly harmful vapors or other volatile substances contained in an adhesive can be avoided and at the same time a tight composite element with high strength is achieved.
  • Insulation is particularly preferably provided. This can be arranged with advantage in cavities between the boards.
  • an insulating layer can be provided. This is usually arranged subsequent to a composite element, preferably between two composite elements.
  • the insulation or the insulation layer can comprise one or more different insulation materials.
  • Such insulating materials can be, for example, jasmine insulation, wood shavings and/or clay. It can be provided that a single insulating material or a combination of several insulating materials is used.
  • the wooden nails are provided for stabilization.
  • the wooden nails are advantageously inserted perpendicularly to the longitudinal direction in the composite element, in particular driven in, so that several boards lying one above the other are connected by them.
  • the wooden nails are in an interior of multiple layers having composite element arranged so that the wooden nails do not pierce the outermost layers and the wooden nails are therefore not visible from both an upper side and an underside of the composite element.
  • a further advantage results from a building with at least one composite element, the at least one composite element being 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 aim 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.
  • a composite element as a vapor barrier, wall panel and/or load-bearing element in and/or in a building.
  • the procedural goal is achieved with a method of the type mentioned at the outset, in which at least three boards according to the invention are provided, after which a first board and a second board are arranged next to one another, after which a first projection of the first board and a second projection of the second board are combined into one Recess of a third board are introduced, so that the boards are fixed positively perpendicular to a longitudinal axis of the boards.
  • the boards are formed from dry lumber.
  • any wood can be used for a composite element according to the invention, but it is favorable if the timber used has a bulk density of at least 500 kg/m 3 and/or a thermal vapor diffusion resistance of at least 10, in particular at least 30.
  • multi-layer solid wood panels can also be used as construction timber. By using such a wood, the function of the composite element as a vapor barrier is guaranteed.
  • the composite element is and/or will be moistened.
  • This increases the volume of the wood used.
  • the boards increase in size accordingly, as a result of which a contact pressure of the projections in the recesses increases and thus connection points between the boards are strengthened be so that a particularly strong and backlash-free connection or a press fit is achieved, which in turn ensures a high level of tightness of the composite element.
  • the connection by means of a press fit is thus essentially impossible to detach manually. Moistening can take place on the one hand actively, for example by steaming with steam, or passively by the mere absorption of atmospheric moisture by the composite element.
