Definitions

  • the invention relates to a wooden building block, a kit for the production of the wooden building block according to the invention and a wall element made of wooden building blocks and can be used in the building industry both in the individual and in the industrial construction of environmentally friendly buildings.
  • Buildings made of wood as the primary building material have been known for a long time. Also known are wooden building blocks which, when put together, form walls and partitions.
  • a cuboid building block made of wood with form-fitting elements for producing a plug-in connection between several building blocks is known, which is characterized in that the form-fitting elements, which are formed by troughs and/or teeth, are arranged at least on one side of the building block.
  • the invention is based on the object of creating a wooden building block which can be produced easily and inexpensively, can be processed effectively and meets high ecological requirements.
  • a further object of the invention is to provide a kit for producing the wooden building block according to the invention.
  • Such wooden building blocks according to the invention are used for the realization of walls.
  • Such wooden building blocks include wooden building elements, which can be outer wall elements and inner wall elements as well as other wooden building elements.
  • a particular advantage of the invention is the simple structural design of the wooden building block according to the invention, in which two outer wall elements enclose at least one inner wall element, with the inner wall element lying against the outer wall elements and, if necessary, further inner wall elements being offset in the vertical and horizontal direction relative to the outer wall elements in such a way that they are opposite one another tongues and grooves result.
  • several inner wall elements can also be present and arranged between the outer wall elements. It should be understood that if only one inner wall element is mentioned below, this is to be understood as at least one inner wall element and thus several inner wall elements can also be present.
  • the enclosing of the inner wall element by the two outer wall elements is to be understood as a planar contact between the side surface of the respective outer wall element facing the inner element and a corresponding side surface of the inner element facing the respective outer wall element.
  • At least one first groove and a corresponding first tongue in the vertical direction and also at least one second groove and a corresponding second tongue in the horizontal direction result in pairs.
  • the wooden building blocks are formed uniformly and each have a groove and a corresponding tongue both in the vertical direction and in the horizontal direction.
  • the wooden blocks can thus be coupled in a simple manner with structurally identical wooden blocks in the vertical direction and in the horizontal direction to create walls.
  • the at least one interior wall element is preferably a first interior wall element, with the wooden building block having two first interior wall elements and also at least one second interior wall element, and the first interior wall elements being offset relative to the exterior wall elements and the second interior wall element, such that in one wall the first interior wall elements are opposite to the Outer wall elements and the second inner wall element are arranged offset in the vertical and horizontal direction, resulting in opposite two grooves and two tongues. Consequently the load distribution is improved by two grooves and two tongues, which can each be brought into engagement with corresponding grooves and tongues of adjacent wooden building blocks. Furthermore, the wall thickness, which is determined by the depth of the two outer wall elements, the two first inner wall elements and the second inner wall element, can thus be increased. A greater wall thickness advantageously enables better insulation and a higher load-bearing capacity of walls.
  • the two outer elements and the at least one inner wall element are designed as rectangular panels with a transverse side and a longitudinal side, with the length of the transverse side and the longitudinal side of the two outer wall elements preferably being equal to the length correspond to the transverse side and the longitudinal side of the inner wall element, in particular the first inner wall elements and the at least one second inner wall element.
  • the inner wall elements and the outer wall elements are designed as rectangular plates, grooves and tongues can be provided in a simple manner by offsetting the inner wall elements relative to the outer wall elements, by the uniform design of the longitudinal and transverse sides of said inner wall elements and outer wall elements.
  • a wooden building block can be provided with tongues and grooves formed in pairs opposite one another on its end faces and longitudinal sides. This wooden building block can then be coupled to another wooden building block on its long sides and front sides. An exact alignment of the wooden blocks in the vertical direction or in the horizontal direction within the wall is not necessary.
  • the wooden building blocks can thus be arranged in rows for building houses, similar to other stones, for example bricks, with the stones in the respective row being arranged laterally offset in relation to the stones in adjacent rows.
  • the tongues and the grooves preferably extend completely along the respective transverse side or longitudinal side of the wooden building block.
  • the length, ie the longitudinal extent, of the springs is determined by the length of the first transverse sides or longitudinal sides of the inner wall element or of the first inner wall element.
  • the length, ie the longitudinal extension, of the grooves is correspondingly defined by the length of the opposite second transverse sides or longitudinal sides of the inner wall element or the first inner wall element.
  • the at least one inner wall element and/or the two outer wall elements preferably comprise solid wood and/or a wood material. If wood is used as a building material or raw material, a distinction is made between so-called solid wood and wood-based materials. Solid wood is, for example, boards or beams that are cut from tree trunks using the manufacturing process cutting. Wood-based materials, on the other hand, are composites in which processed wood products such as e.g. B. wood wool or chips with or without glue or with mineral binders. Wood-based materials are increasingly being used as building materials or insulating materials.
  • the at least one inner wall element and/or the two outer wall elements are preferably made of solid wood. More preferably, the fiber direction of the wood is oriented in the longitudinal direction of at least one inner wall element and/or outer wall element.

  • the orientation of the wood fibers in the finished wood products determines their mechanical properties.
  • wood has a high tensile strength in the direction of the grain, whereas the tensile strength across the grain is only about 10 percent of this.
  • wooden products are usually manufactured in such a way that the grain of the wood is in the direction of the maximum load in the subsequent component.
  • the anisotropic properties of the solid wood by the varying orientation of the Balanced wood fibers and provided a wooden building block with improved strength properties in different spatial directions.
  • the wood-based material preferably comprises glued wood and/or glued laminated wood and/or laminated wood and/or chipboard and/or OSB and/or recycled wood and/or a wood fiber board. Inexpensive wood-based materials can thus be used and their thermal and mechanical properties can be combined in a suitable manner.

  • specially treated outer wall elements can be reliably positioned on the outer wall of the respective wall.

  • the outer wall elements and/or the inner wall element are preferably formed in segments. More preferably, the wooden building block extends in a longitudinal direction, with the segments being arranged adjacent to one another, in particular adjacent to one another, in the longitudinal direction. Thus, in particular, shorter segments can also be used, which in their entirety form the longitudinal extension of the wooden building block.

  • the segments are uniformly formed as rectangular plates or as diamond-shaped plates.
  • the segments in a wall are either arranged upright, in the rectangular plate configuration, or inclined from the vertical, in the diamond-shaped plate configuration.
  • the outer wall elements are connected to the one or more inner wall elements, preferably the first inner wall elements and the one or more second inner wall elements by screws and/or nails and/or wooden dowels and/or adhesives and/or wooden pins and/or wood welding processes.

  • the second inner wall element 3 is formed parallel to the outer wall elements 1a and 1b, i.e. the transverse sides 9a, 9b and longitudinal sides 9c, 9d of the second inner wall element 3 are arranged parallel to the transverse sides 7a, 7b and longitudinal sides 7c, 7d.
  • the wooden building block 100 has two outer wall elements 1a and 1b and five inner wall elements 2a, 2b, 2c, 3a and 3b.
  • This embodiment variant thus has a total of seven wall elements, of which the first inner wall elements 2a, 2b and 2c in a wall are offset upwards and to the right.
  • This arrangement of the first inner wall elements 2a, 2b and 2c results in the first inner wall elements 2a, 2b and 2c protruding above the outer wall elements 1a and 1b and the second inner wall elements 3a and 3b and the three longitudinal tongues 4a', 4b', 4c' form and protrude on the right side, and form the three transverse springs 4a, 4b, 4c.
  • the grooves 5a, 5b, 5c, 5a', 5b', 5c' are formed opposite the tongues 4a, 4b, 4c, 4a', 4b', 4c'.
  • the second inner wall elements 3a and 3b ie their transverse sides 9a, 9b and longitudinal sides 9c, 9d, are arranged parallel to the outer wall elements 1a and 1b, ie their transverse sides 7a, 7b and longitudinal sides 7c, 7d.
  • FIG. 4a, 4b and 4c The overview representations shown essentially correspond to the representations of Figures 2a, 2b and 2c , wherein in this overview representation of the wooden building block 100 with two outer wall elements 1a and 1b and three inner wall elements 2a, 2b and 3, the outer wall elements 1a, 1b each additionally have a long side 7c designed as an outwardly sloping bevel 12.
  • the slope 12 means that moisture can run off and does not penetrate into the interior of the wooden building block 100 . This achieves a high level of weather resistance.
  • kit for producing a wooden building block 100 is not explicitly shown in the figures, but for the person skilled in the art, among other things, based on Figures 1a to 4c and the description obvious and understandable.
  • the individual production of a wooden building block from such a kit takes place by assembling two outer wall elements 1a, 1b with at least one inner wall element 2a, 2b, 2c, 3a, 3b, the outer wall elements 1a, 1b and the inner wall elements 2a, 2b, 2c, 3a, 3b preferably have pre-drilled holes for connecting elements.
  • the bores are arranged in such a way that selected first inner wall elements 2a, 2b, 2c are positioned offset relative to the outer wall elements 1a, 1b in the installed state in a wall in the vertical and horizontal direction by inserting the connecting elements in such a way that pairs of transverse grooves 5a , 5b, 5c and tongues 4a, 4b, 4c and longitudinal grooves 5a', 5b', 5c' and tongues 4a', 4b', 4c'.
  • the connecting elements are screws and/or wooden dowels.
  • Each of the two corner connections 13 is presently formed by a number of second transverse sides 7b, 8b, 9b of the two first inner wall elements 2a, 2b, the second inner wall element 3 and the two outer wall elements 1a, 1b. At least a portion of the second transverse sides 7b, 8b, 9b is offset from the first outer wall element 1a towards the second outer wall element 1b in steps.
  • the corner connections 13 of the two wooden building blocks 100, 100' are designed to correspond to one another, so that the stepped second transverse sides 7b, 8b, 9b of the first wooden building block 100 can be brought into contact with the stepped second transverse sides 7b, 8b, 9b of the second wooden building block 100' are.
  • the first wooden building block 100 has two grooves 5a, 5b opposite the corner connection 13, which are formed by the first transverse sides 7a, 8a, 9a.
  • the first transverse sides of the first two inner wall elements 2a, 2b are set back compared to the first transverse sides 7a, 9a of the second inner wall element 3 and the two outer wall elements 1a, 1b.
  • the first inner wall elements 2a, 2b are offset to the outer wall elements 1a, 1b and the second inner wall element 3 in a known manner in a horizontal offset V h and a vertical offset V v - in relation to the arrangement of the wooden block in a wall.
  • the longitudinal sides 8c of the two first inner wall elements 2a, 2b protrude from the longitudinal sides 7c of the two outer wall elements and the second inner wall element 3, are therefore arranged offset to them, and thus form two longitudinal tongues 4a', 4b'.
