Definitions

  • the invention relates to a composite element formed by at least three identical boards, the boards 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 a method for producing such a composite element.
  • EP 2 821 191 A1 a panel element made of wood, which consists of at least two layers of parallel boards arranged next to one another, with boards of two layers being connected to one another by dovetail connections.
  • the dovetail connections are hereby dovetail-shaped along a longitudinal direction of a board Recesses and projections are formed, with recesses and projections being oriented transversely to the longitudinal direction.
  • dovetail connections designed in this way have the disadvantage that a contact surface per dovetail connection 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 fixation, such as pins and other connecting elements are provided.
  • additional means for fixation such as pins and other connecting elements are provided.
  • producing such a board is very complex because each board has a large number of milled edges.
  • the object of the invention is therefore to provide a board of the type mentioned, which is easy to produce and at the same time enables a firm, positive connection of several boards to form a multi-layer composite element, such as a panel or beam.
  • a further aim of the invention is to provide a use for a composite element formed from such boards.
  • the invention is a composite element according to claim 1.
  • a board according to the invention can, for example, be designed in such a way that only one recess is provided on the top and/or bottom of the board, which is delimited, for example, by projections. This results in very low production costs, as 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 thus engage into the recess of another board, that two such projections find space in a recess.
  • 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 usually amounts to one 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°.
  • the recess can 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.
  • 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 one top 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 a plurality of identical boards are arranged, a second board arranged next to a first board is 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 boards connected to one another can have, in addition to the inner contact surface and the side contact surface, a further contact surface between the first projection of the first board and the second projection of the second board, with a connection of several boards gaining in stability as the number of contact surfaces increases.
  • 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 connection in at least one 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.
  • boards located next to each other are connected via a groove and bung connection.
  • 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 that terminate the composite element on a top and/or bottom is designed without recesses and projections.
  • boards can be arranged on one outside only with projections and recesses on one side and boards with recesses and projections arranged on both the top and bottom can be arranged between the boards arranged on the outside, with projections and recesses of all boards usually having approximately corresponding dimensions exhibit.
  • the overlap width of the boards corresponds to approximately half the width of the board. 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 guaranteed that boards located next to each other have a common contact surface. Alternatively, an asymmetrical overlap can be provided. In order to ensure tightness and a contact surface between adjacent boards, it is important, however, that when three boards are connected, in which a first board is arranged next to a second board and the first board is positively connected to the second board by a third board arranged on these boards are connected, the sum of the overlap widths of the first board with the third board and the second board with the third board results in the total board width of the third board.
  • the overlap widths can be, for example, 1 ⁇ 3 and 2 3 correspond to the board width.
  • the press fit is particularly advantageous because it means that 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 advantageously be arranged in cavities between the boards. Additionally or alternatively, an insulating layer can be provided. This is usually arranged next to a composite element, preferably between two composite elements.
  • the insulation or the insulation layer can comprise one or more different insulation materials. Such insulation 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 into the composite element perpendicular to the longitudinal direction, in particular hammered in, so that several boards lying one above the other are connected by them.
  • the wooden nails are preferably in several layers inside having composite element arranged so that the wooden nails do not pierce outermost layers and the wooden nails are therefore not visible from both the top and bottom of the composite element.
  • the further goal 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 particular advantage arises from the fact that such a composite element has increased health and environmental compatibility.
  • the boards are made from dry lumber.
  • any wood can be used for a composite element according to the invention, but it is advantageous 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 at least 30.
  • multi-layer solid wood panels can also be used as lumber. The use of such wood ensures that the composite element functions as a vapor barrier.
  • the composite element is and/or is moistened.
  • the connection by means of a press fit therefore essentially becomes inseparable manually. Humidification can be done actively, for example by steaming with water vapor, or passively by simply absorbing air moisture through the composite element.
  • 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 arranged on an upper side of the board 1, so that the board 1 is essentially C-shaped Has cross section.
  • an inner contact surface 5 is provided, which encloses an angle 7 with a side contact surface 6.
  • at least one angle 7 lies in a range between 0° and 180°.
  • Fig. 1b shows one for display in Fig. 1a Analogous design of the board 1, with two recesses 2 and four projections 3, 4, 11 being provided.
  • the recesses 2 as well as the first projections 3, 4, 11 and the second projections 3, 4, 11 are each provided on the top and on a bottom, so that the board 1 has a substantially H-shaped cross section.
  • the top and bottom sides are those sides which correspond to the two longer sides in a cross section perpendicular to the longitudinal direction of the board 1.
  • 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, i.e. only on the top, or on both sides, i.e. both on the top and on the bottom .

  • Fig. 2a shows a board 1 according to the invention with a single recess 2, which is delimited by the first projection 3 and the second projection 4.
  • this board 1 has a bung 9 on the side contact surfaces 6 on the one hand and a groove 10 on the other.
  • a bung 9 or the groove 10 enlarges a lateral contact surface 6 and enables a tighter and more stable connection of several identical boards 1.
  • Fig. 2b shows a two-layer composite element 8, with several identical, one-sided profiled boards 1, each of which has a bung 9 and a groove 10, being connected.
  • a first board 1 is 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 positively fixed in every direction with the exception of the longitudinal direction of the boards 1.
  • Figs. 2c and 2d each show multi-layer composite elements 8, with middle layers being formed by boards 1 with a profile on both sides.
  • a first board 1 profiled on one side is thus positively connected in a lowermost position to an identical second board 1 arranged next to it by a third board 1 arranged on it, the third board 1 being designed with a profile on both sides.
