Definitions

  • the invention relates to a wooden lamella for the production of structural timber components, for example of cross-laminated timber, cross-laminated timber panels or beam elements, structural timber components produced with such wooden lamellae, for example, cross-laminated board or beam elements, and a method for the production of wood laths.
  • the product cross laminated timber (also referred to as thick wood, X-Lam, BSP or cross laminated wood) has recently gained great importance in the construction industry.
  • These are large-scale elements for wall, ceiling or roof, which consist of preferably crosswise glued wooden slats (solid wood boards), with floor to ceiling walls are made for example in the format of 3 mx 16 m, which consist of three to seven layers of wood depending on use and Have thicknesses of about 60 mm to 300 mm.
  • Cross laminated timber is usually produced industrially, with mostly boards of dry softwood being used as raw material for the individual layers. These are glued together with adhesives approved for load-bearing timber components.
  • multilayer wood components or building panels made of wood materials between two cover layers of thin chip, solid wood or plywood to use a middle layer of solid wood, in which a cell-like structure is milled or cut, creating internal cavities in the building board.
  • the middle layer is made of sideways (marginal boards from the log, sometimes with tree edge) or main product, all softwood and hardwood species are suitable.
  • the wooden building board serves as a construction element for ceilings, walls or roofs of a room.
  • the wooden building board consists of several interconnected layers, which on one build up a base layer formed by a transverse layer or plate. With the transverse layer a ribbed layer is connected, which consists of individual elements - constructed of parallel glued boards of increasing width - whose cross-section increases outwards to the panel flat side.
  • the thus formed, outwardly open, elongated cavities serve to accommodate installation material and / or sound or heat-insulating material.
  • a lightweight board for example as an acoustic panel or furniture board, known, which consists of solid wood slats, which have lateral recesses for weight saving, which are produced by milling.
  • solid wood slats which have lateral recesses for weight saving, which are produced by milling.
  • the object of the invention is to improve wooden slats for the production of structural timber components, for example of cross-laminated timber, cross-laminated timber, or beam elements, or their production in terms of material savings and weight reduction at approximately constant strength values, with a resource-saving production is to be made possible.
  • the wood slat is designed as a hollow slat and consists of several layers of parallel aligned, glued together individual boards, wherein in at least one layer, the individual boards are at least partially arranged with lateral spacing from one another and form cavities.
  • the cavities may at least partially accommodate installation material, heat-insulating material and / or sound-absorbing material.
  • the cavities can also be arranged in an outer layer or cover layer of individual boards and serve, for example, to accommodate installation conduits.
  • the invention in a first step, hollow slats (composite elements of individual boards) produced and can then be assembled in a second step by laminar, multilayer gluing the hollow slats completely flexible to a large-sized, structural timber component.
  • the structural timber components can - depending on the purpose - Fully made of hollow slats best, or at least partially have solid wood slats in individual layers.
  • the individual boards may have a thickness of 0.5 cm to 5 cm, preferably 10 mm to 20 mm, and be made, for example, at least partially obtained from sawmill waste or sidewalls.
  • Hollow slats can be made from sawn, thick calibrated or planed single boards.
  • Fig. 1 For the production of hollow slats according to the invention are - as in Fig. 1 shown - first several layers a, b, c of parallel aligned individual boards 2 glued to a sheet 4, wherein the individual boards 2 of the middle layer b are at least partially arranged with a lateral distance y to each other.
  • the sheet 4 has three layers a, b, c, of individual boards 2 a thickness of 0.5 cm to 5 cm, preferably from 10 mm to 20 mm, but it would also arrangements of, for example, five layers conceivable , wherein in the second and fourth layers formed by board spacing cavities 3 are formed.
  • the height x of the cavities 3 corresponds to the thickness of the individual boards 2 of the layer b, wherein also different board thicknesses can be installed, so that for example the single boards 2 of the outer layers a, c are made thicker than the single boards 2 of the middle layer b.
  • the flat panel 4 is separated by saw cuts guided parallel to the individual boards 2, the sectional planes ⁇ standing substantially normal to the plane of the flat panel 4.
  • Each hollow lamella 10 10 'thus consists of several layers a, b, c aligned parallel, glued individual boards 2, wherein in at least one layer b, the individual boards 2 are at least partially arranged with a lateral distance y to each other and cavities 3, 3' with the length of the single boards 2 train.
  • the slightly wider hollow slat according to Fig. 4 (For example, with a width of 25 cm and a thickness of 3 cm) consists of three layers a, b, c of single boards 2, which are glued together at all contact surfaces, the middle layer b narrower, for example, about half as wide single boards 2, as the outer layers a and c.
  • the lateral impact areas 5 of the individual boards 2 of the outer layers a and c are supported, so that a very stable hollow lamella 10 with three elongated cavities 3 is formed.
  • the individual boards 2 of the inner layer b need not necessarily be cut at right angles at the edges (seamed), so that the optimal use of material results from the at least partial use of side fabric.
  • Fig. 5 shows a wooden component, for example, a cross-laminated board 1, which consists in the example shown of three layers A, B, C of preferably cross-glued wooden slats 10 or 10 ', in the example shown, all wooden slats by hollow slats 10 according to Fig. 2 are replaced. It is also possible to use only solid wood slats in individual layers, for example in the outer layers A, C for reasons of strength or provide in individual layers, for example in the edge regions solid wood slats same thickness as the hollow slats, if anchoring, mounting or fastening means of the timber component here attack or are trained. Furthermore, soffit profiles can be formed on the edge regions of the timber component.
  • the hollow slats 10, 10 'of adjacent layers A, B, C may include an angle between 45 ° and 90 °, preferably in the range of 90 °.
  • Fig. 6 shows a wooden component, for example, beam element 1 ', in which the hollow plates 10 of the two layers A and B are aligned parallel to each other.
  • beam element 1 ' a wooden component
  • the hollow plates 10 of the two layers A and B are aligned parallel to each other.
  • slim bars and beams can be realized in the framework.
