WOODEN BUILDING BLOCK, BUILDING KIT FOR A WOODEN BUILDING BLOCK AND WALL ELEMENT

Description

[0001] The invention relates to a wooden building block, a kit for producing the wooden building block according to the invention and a wall element made of wooden building blocks and is applicable in construction both for the individual and industrial construction of environmentally friendly buildings.

[0002] Buildings made of wood as a primary construction material have been around for a long time. Wooden blocks, which, when assembled, form walls and partitions, are also well known.

[0003] For example, DE 10 2018 204 154 B3 describes a wooden building block with four longitudinal timbers of square cross-section, which are arranged parallel and spaced apart from one another in such a way that they span a square at the end with at least six cross timbers of square cross-section and with at least two dowels of square cross-section, wherein at least four cross timbers are arranged upright and at least two cross timbers are arranged horizontally.

[0004] From DE 201 17 888 U1, a cuboid-shaped wooden building block with form-locking elements for creating a plug-in connection between several building blocks is known, which is characterized in that the form-locking elements, which are formed by recesses and / or teeth, are arranged at least on one side of the building block.

[0005] A wooden building block according to the preamble of claim 1 is shown in AT A1339 2000 A, US 2004 / 163352 A1, and FR 915 097 A. Furthermore, EP 0 606 633 A2 shows various wooden building blocks cut from a single piece of so-called softwood, some of which have tongues and grooves. CA 2 410 045 A1 shows a wooden building block consisting of an interior wall element and two exterior wall elements, the interior wall element being smaller than the exterior wall elements.

[0006] The invention is based on the object of creating a wooden building block which is easy and inexpensive to produce, can be processed effectively and meets high ecological requirements.

[0007] A further object of the invention is to provide a kit for producing the wooden building block according to the invention.

[0008] This object is achieved in a first aspect by a wooden building block according to claim 1. Expedient embodiments of the invention are contained in the subclaims.

[0009] Such wooden building blocks according to the invention are used to construct walls. Such wooden building blocks include wooden construction elements, which can be exterior wall elements, interior wall elements, and other wooden construction elements.

[0010] A particular advantage of the invention lies in the simple structural design of the wooden building block according to the invention, in that two outer wall elements enclose at least one inner wall element, wherein the inner wall element adjacent to the outer wall elements and optionally further inner wall elements are arranged offset relative to the outer wall elements in the vertical and horizontal direction such that opposing grooves and tongues are formed. Within the meaning of the invention, therefore, 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.

[0011] To create walls, several wooden building blocks are coupled together in an upright position. It should be understood that, with respect to this upright position, the respective interior wall element is offset relative to the exterior wall elements in such a way that the offset runs horizontally and vertically. According to the invention, this offset in a wall, realized by upright wooden building blocks, enables each wooden building block to have at least one tongue and groove opposite one another in the vertical and horizontal directions. It should be understood that, for a wooden building block that is, for example, in a transport position, the offset can of course also be in other directions or planes.

[0012] The inventors advantageously recognized that the offset in the horizontal and vertical directions when constructing walls using the inventive wooden building blocks provides mounting interfaces both vertically and horizontally, via which the respective wooden building block can be coupled with adjacent wooden building blocks in the horizontal and vertical directions. This advantageously results in a plug-in system made of such wooden building blocks that can be used to construct walls.

[0013] In the sense of the invention, 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.

[0014] More preferably, at least one first groove and a corresponding first tongue are formed in pairs in the vertical direction, and at least one second groove and a corresponding second tongue are formed in the horizontal direction. Thus, the wooden building blocks are uniformly formed and each have a groove and a corresponding tongue in both the vertical and horizontal directions. The wooden building blocks can thus be easily coupled with identical wooden building blocks in the vertical and horizontal directions to create walls.

[0015] Preferably, the at least one interior wall element is a first interior wall element, wherein the wooden building block has two first interior wall elements and furthermore at least one second interior wall element, and the first interior wall elements are arranged offset with respect to the outer wall elements and the second interior wall element such that, in a wall, the first interior wall elements are arranged offset in the vertical and horizontal directions with respect to the outer wall elements and the second interior wall element, so that two grooves and two tongues are formed opposite one another. The load distribution is thus 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 interior wall elements and the second interior wall element, can thus be increased.A greater wall thickness advantageously enables better insulation and a higher load-bearing capacity of walls.

[0016] According to a preferred embodiment, the two outer elements and the at least one inner wall element, in particular the first inner wall elements and the at least one second inner wall element, are designed as rectangular panels with a transverse side and a longitudinal side, wherein the length of the transverse side and the longitudinal side of the two outer wall elements preferably correspond to the length of the transverse side and the longitudinal side of the inner wall element, in particular of the first inner wall elements and the at least one second inner wall element. By designing the inner wall elements and the outer wall elements as rectangular panels, tongues and grooves can be provided in a simple manner by offsetting the inner wall elements relative to the outer wall elements, and by uniformly designing the longitudinal and transverse sides of said inner wall elements and outer wall elements.In other words, by offsetting panels that are identical in size and comprise one or more first and preferably second interior wall elements and two exterior wall elements, and coupling them together, a wooden building block can be provided with tongues and grooves formed in pairs on its opposite end faces and long sides. This wooden building block can then be coupled to another wooden building block on its long sides and end faces. An exact alignment of the wooden building blocks in the vertical or horizontal direction within the wall is not necessary. The wooden building blocks can thus be arranged in rows in a similar way to other stones, such as bricks, for building a house, with the stones in each row being arranged laterally offset from the stones in neighboring rows.

[0017] The tongues and grooves preferably extend completely along the respective transverse side or longitudinal side of the wooden building block. The length, i.e., the longitudinal extent, of the tongues is defined by the length of the first transverse sides or longitudinal sides of the interior wall element or the first interior wall element. The length, i.e., the longitudinal extent, of the grooves is defined accordingly by the length of the respective opposite second transverse sides or longitudinal sides of the interior wall element or the first interior wall element.

[0018] The at least one interior wall element and / or the two exterior wall elements preferably comprise solid wood and / or a wood-based material. When wood is used as a building material or construction material, a distinction is made between so-called solid wood and wood-based materials. Solid wood, for example, refers to boards or beams that are carved from tree trunks using the cutting process. Wood-based materials, on the other hand, are composite materials in which processed wood products such as wood wool or chips are bonded with or without adhesive or with mineral binders. Wood-based materials are increasingly used as building materials or insulation materials.

[0019] Preferably, the at least one interior wall element and / or the two exterior wall elements are made of solid wood. Further preferably, the grain direction of the wood of at least one interior wall element and / or exterior wall element is oriented in the longitudinal direction. Further preferably, the grain direction of the wood of at least one interior wall element and / or exterior wall element is oriented at an offset angle of maximum 90° to the longitudinal direction and, in particular, is arranged diagonally to the longitudinal direction. Particularly preferably, the wooden building block comprises at least one interior wall element with a first grain direction of the wood and furthermore at least one interior wall element and / or exterior wall element with a second grain direction of the wood that is different from the first grain direction of the wood. Since wood is a material with high anisotropy, i.e.While mechanical properties are direction-dependent, the orientation of the wood fibers in the finished wood products determines their mechanical properties. For example, wood exhibits high tensile strength along the grain, whereas the tensile strength across the grain is only about 10 percent of that. For this reason, wood products are usually manufactured with the grain oriented in the direction of maximum load in the final component. Thus, the anisotropic properties of solid wood are balanced by the varying orientation of the wood fibers, providing a wood building block with improved strength properties in various spatial directions.

[0020] The wood-based material preferably comprises glued laminated timber, glued laminated timber, laminated wood, particle board, OSB, recycled wood, and / or a wood fiber board. This allows the use of cost-effective wood-based materials and the appropriate combination of their thermal and mechanical properties.

[0021] It is also preferred that the two outer wall elements and the inner wall element or a plurality of inner wall elements are formed as substantially rectangular plates, wherein, in particular, recesses are provided on the respective tongues and projections corresponding to the recesses are provided on the grooves, wherein the projections can be brought into engagement with the recesses. The longitudinal sides or transverse sides of the corresponding inner wall elements and outer wall elements are thus shaped like the battlements of a fortification or wall.

[0022] Preferably, the depth of the second exterior wall elements and the interior wall element, in particular of the one or plurality of first interior wall elements and / or second interior wall elements, is different. Thus, by varying the depths of the respective interior wall elements and exterior wall elements and thus also by the different depths of the grooves and tongues formed therefrom, a repeatable orientation or alignment of the respective wooden building blocks in a wall can be ensured. This can, for example, ensure that one of the exterior wall elements is positioned on the outside of the wall and the other exterior wall element is positioned on the inside of the wall, for all of the wooden building blocks installed in the wall. Thus, for example, specially treated exterior wall elements can be reliably positioned on the outer wall of the respective wall.

[0023] An additional advantage of an embodiment according to the invention is the efficient use of materials for the production of the wooden building block, as the interior wall elements are formed in segments. This makes it possible to process even shorter woods.

[0024] According to the invention, the outer wall elements and / or the inner wall element, in particular the one or the plurality of first inner wall elements and / or second inner wall elements, are formed in segments. Furthermore, the wooden building block extends in a longitudinal direction, with the segments being arranged 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.

[0025] When the wooden block is assembled, the individual segments are preferably arranged vertically in a wall, but can also be arranged inclined or diagonally.

[0026] More preferably, the segments are uniformly formed as rectangular panels or diamond-shaped panels. Thus, the segments are arranged in a wall either vertically, in the case of a rectangular panel design, or inclined relative to the vertical, in the case of a diamond-shaped panel design.

[0027] In particular, the exterior wall elements are connected to the one or more interior wall elements, preferably the first interior wall elements and the one or more second interior wall elements, by screws and / or nails and / or wooden dowels and / or adhesives and / or wooden pins and / or wood welding processes. The screws and / or nails preferably comprise a wood-based material, in particular synthetic resin-based pressed wood. By pressing wood veneers under high pressure and temperature and adding polymer resin, the strength properties of the nails can be improved.

[0028] Particularly preferably, the screws and / or nails are made of wood. Further preferably, the outer wall elements and the inner wall elements are made of a biodegradable material, in particular wood, so that the wooden building block is completely biodegradable. A further advantage of the wooden building block according to the invention is the secure cohesion of the individual components, in that the outer wall elements are connected to the inner wall elements by at least one of these connecting means.

[0029] Preferably, the one or more interior wall elements are arranged offset horizontally and vertically relative to the exterior wall elements in a wall, with the horizontal and vertical offsets being different. Thus, taking into account the loads occurring in the wall, the length of the tongues and grooves can be adjusted as needed by the corresponding horizontal and vertical offset—relative to the vertical arrangement of the respective wooden building block in a wall.

[0030] Another advantage is that the wooden building blocks according to the invention are of high quality, as they are made of solid kiln-dried wood. High weather resistance is achieved by the fact that the exterior wall elements have an outwardly sloping slope. In particular, the exterior wall elements and the one interior wall element, preferably the one or more first interior wall elements and second interior wall elements, are made of solid kiln-dried wood.

[0031] According to the invention, assembly interfaces in the form of tongues and grooves are provided on at least three sides of the wooden building block. The tongues are designed to engage the grooves of adjacent wooden building blocks according to the invention. In a wall, the wooden building blocks can thus be coupled or engaged with one another vertically and horizontally by means of the grooves and tongues in order to create a wall. In this case, the transverse side is understood to be the shorter side of the respective panel-shaped interior wall or exterior wall elements, and the longitudinal side is understood to be the longer side of the respective panel-shaped interior wall or exterior wall elements. The third side is provided by a depth, whereby the depth of the respective interior wall elements and exterior wall elements can be identical or different.

[0032] The tongues and grooves preferably extend completely along the respective transverse side or longitudinal side of the wooden building block. The length, i.e., the longitudinal extent, of the tongues is defined by the length of the first transverse sides or longitudinal sides of the interior wall element or the first interior wall element. The length, i.e., the longitudinal extent, of the grooves is defined accordingly by the length of the respective opposite second transverse sides or longitudinal sides of the interior wall element or the first interior wall element.

[0033] Preferably, the transverse side of the exterior wall elements is designed as a slope that slopes outward relative to the transverse side of the interior wall element. This allows water penetrating between two adjacent wooden blocks, such as rain or condensation, to be drained away via the sloped transverse side of the respective exterior wall elements, as this slope slopes outward, i.e., has an angle of inclination relative to the horizontal of 0° > α > -90°. This increases the weather resistance of the wooden blocks.

[0034] Further preferably, the interior wall element is a first interior wall element, and the wooden building block further comprises at least one second interior wall element, wherein the second interior wall element comprises an insulating material and is in particular made entirely of an insulating material. Such an insulating material can be, for example, a wood fiberboard.

[0035] Preferably, a plasterboard or an insulation board or a wood paneling and / or a wall cladding is also attached to at least one external wall element.

[0036] The wooden building block preferably has a plurality of first inner wall elements, each forming one or more tongues and one or more grooves. Preferably, at least one of the tongues is a longitudinal tongue, with one of the grooves being opposite the longitudinal tongue. Furthermore, at least one of the tongues is preferably a transverse tongue, with one of the grooves being opposite the transverse tongue.

[0037] More preferably, the longitudinal tongues have a first depth, defined by a first, in particular horizontal, offset, and the transverse tongues have a second depth, defined by a second, in particular horizontal, offset. The second depth is preferably greater than the first depth. This allows for reliable force transmission in accordance with the load, and increases the stability of the wall. Grooves or tongues with different depths ensure the relative arrangement of several wooden building blocks, since not all grooves and tongues can be combined.

[0038] Preferably, a longitudinal side or a transverse side of the interior wall element has a functional element, in particular a window frame section, a door frame section, or a seal. Such a functional element allows, for example, doors or windows to be easily integrated into a wall constructed using the wooden building blocks according to the invention. The functional element is preferably designed to accommodate such doors, windows, or even roof structures.

[0039] According to a further preferred embodiment, the wooden building block further comprises a front-side corner connection, which is formed by a number of second transverse sides of the interior wall element, in particular of the one or more first interior wall elements and second interior wall elements, as well as of the two exterior wall elements. The second transverse sides of the first exterior wall element are offset in a step-like manner relative to the second exterior wall element. The step-like offset of the transverse sides provides a corner connection which can be brought into engagement with a corresponding corner connection of a second wooden building block. Due to the step-like offset, the exterior wall element on the outside in a wall has a greater length or longitudinal side than the exterior wall element arranged on the inside. Thus, structures consisting of several walls, which in particular also extend over corners, can be realized.

[0040] The wooden building block according to the invention can be manufactured industrially as a prefabricated component and delivered in a similar way to conventional building blocks. However, it is also possible to provide a kit for producing a wooden building block.

[0041] The invention solves the problem mentioned at the outset in one aspect by a construction kit according to claim 11 for a wooden building block according to the invention.

[0042] In this respect, reference is made to the advantages described, which such a kit for a wooden building block also has.

[0043] The wooden building block is thus individually manufactured by assembling two exterior wall elements with at least one interior wall element or even several interior wall elements. The exterior wall elements and the interior wall elements have pre-drilled holes for connecting elements, and the holes are arranged such that pre-drilled interior wall elements are offset vertically and horizontally relative to the exterior wall elements by inserting the connecting elements, creating opposing tongues and grooves. The connecting elements are preferably screws, nails, or wooden dowels.

[0044] By providing a kit for the production of wooden blocks, even large wooden blocks can be transported to an assembly site and transported more easily. The weight of the individual wall elements used to produce the wooden block represents only a fraction of the total weight of the wooden block, making transport easier overall and eliminating the need for cranes or similar equipment. The provision of drill holes also ensures repeatable assembly of the wooden blocks.

[0045] The invention solves the problem mentioned at the outset in a further aspect by a wall element according to claim 13

[0046] Another advantage is that, when constructing walls or buildings, strips of hemp, wood fiber, or an elastic material such as cork can be placed between the individual wooden blocks. This counteracts the negative effects of the natural properties of wood, which tend to expand or contract under certain conditions. It also prevents moisture penetration.

[0047] When erecting walls or buildings, adjacent wooden blocks are preferably additionally connected to one another using screws and / or bolts, in particular metal screws.

[0048] The invention achieves the object mentioned at the outset in a further aspect by the use of a wooden building block according to one of claims 1 to 10 for erecting walls according to claim 12. The method preferably further comprises the arrangement of strips made of, for example, hemp, wood fiber or an elastic material such as cork between the interconnected wooden building blocks, wherein the arrangement preferably takes place before step b). This counteracts the negative effects of the natural properties of the material wood, which tend to expand or contract under certain conditions. In addition, this prevents the penetration of moisture.

[0049] The invention will be explained in more detail below using preferred embodiments with reference to the accompanying figures. They show: Fig.1a an overview of a wooden building block with two outer wall elements and one inner wall element in a plan view, Fig.1b the wooden building block according to Figure 1a in a side view, Fig.1c the wooden block according to Figure 1a in a front view, Fig.2a an overview of a wooden building block with two outer wall elements and three inner wall elements in a plan view, Fig.2b the wooden building block according to Figure 2a in a side view, Fig.2c the wooden block according to Figure 2a in a front view, Fig.3a an overview of a wooden building block with two outer wall elements and five inner wall elements in a plan view, Fig.3b the wooden building block according to Figure 3a in a side view, Fig.3c the wooden block according to Figure 3ain a front view, Fig.4a an overview of a wooden building block with two outer wall elements and three inner wall elements as well as a sloping slope on the outer wall elements in a plan view, Fig.4b the wooden building block according to Figure 4a in a side view, Fig.4c the wooden block according to Figure 4a in a front view, Fig.5a an overview of two wooden blocks connected with a corner connection in a plan view, Fig.5b the first of the two wooden blocks according to Figure 5a in a side view, Fig.5c a second of the two wooden blocks according to Figure 5a in a side view, and Fig.5d the wooden block according to Figure 5a in a perspective view.

[0050] As in the three views according to Fig. 1a, 1b and 1c As shown, the wooden building block 100 according to the invention has two outer wall elements 1a and 1b, which enclose an inner wall element 2 or accommodate it between them.

[0051] The two exterior wall elements 1a and 1b each have two parallel transverse sides 7a, 7b and two parallel longitudinal sides 7c, 7d. The longitudinal sides extend in a longitudinal direction L. The transverse sides 7a, 7b and the longitudinal sides 7c, 7d preferably run perpendicular to each other, so that the exterior wall elements 1a and 1b are each designed as rectangular panels, each with an inner side surface 10a and an outer side surface 10b with a rectangular cross-section Q 10 .

[0052] The inner wall element 2 has two transverse sides 8a, 8b running parallel to one another and two longitudinal sides 8c, 8d running parallel to one another. The longitudinal sides extend in the longitudinal direction L. The transverse sides 8a, 8b and the longitudinal sides 8c, 8d preferably run perpendicular to one another, so that the inner wall element 2 is designed as a rectangular panel with two side surfaces 11a, 11b facing the outer wall elements 1a, 1b and having a rectangular cross-section Q 11 .

[0053] In the embodiment shown, the length of the transverse sides 7a, 7b of the outer wall elements corresponds to the length of the transverse sides 8a, 8b of the inner wall element 2 and the length of the longitudinal sides 7c, 7d of the outer wall elements corresponds to the length of the longitudinal sides 8c, 8d of the inner wall element 2, so that the cross sections Q 10 and Q 11 correspond.

[0054] With regard to the arrangement in a wall to be realized, the inner wall element 2 is arranged offset in the vertical and horizontal direction relative to the outer wall elements 1a and 1b in such a way that, due to the matching cross sections Q 10 and Q 11, a groove 5 and a tongue 4 are formed opposite one another.

[0055] The arrangement of the inner wall element 2, offset upwards by a vertical offset V v and to the right by a horizontal offset V h in the view shown, results in the inner wall element 2 projecting above the outer wall elements 1a and 1b, forming the longitudinal tongue 4', and projecting to the right, forming the transverse tongue 4. The grooves 5, 5' are formed opposite the tongues 4, 4'.

[0056] The tongues 4, 4' and the grooves 5, 5' preferably extend completely along the respective transverse side or longitudinal side of the wooden building block 100. The length, i.e. the longitudinal extent, of the tongues 4, 4' is defined by the length of the first transverse sides 8a or longitudinal sides 8c of the interior wall element 2. The length, i.e. the longitudinal extent, of the grooves 5, 5' is correspondingly defined by the length of the respective opposite second transverse sides 8b or longitudinal sides 8d of the interior wall element 2.

[0057] In the present exemplary embodiment, the inner wall element 2 is segmented and comprises the segments 6a, 6b, 6c, and 6d. The individual segments 6a, 6b, 6c, and 6d are preferably arranged vertically, but can also be arranged inclined or positioned diagonally. It should be understood that with a vertical arrangement of the segments 6a, 6b, 6c, and 6d, the transverse sides of the segments 6a, 6b, 6c, and 6d run perpendicular to the longitudinal direction L. In the case of an inclined arrangement of the segments 6a, 6b, 6c, and 6d, it should be understood that the transverse sides of the segments 6a, 6b, 6c, and 6d are inclined relative to the vertical arrangement described above.

[0058] Of course, the inner wall element 2 can also be formed in one piece, whereby in this embodiment all three wall elements 1a, 1b and 2 have the same dimensions.

[0059] In the present embodiment, the outer wall elements 1a and 1b are connected to the inner wall element 2 by screws not shown in the figure. The screw connection can also be supplemented with adhesive.

[0060] When erecting walls or structures by joining the individual wooden building blocks 100, strips of hemp or cork or another elastic material (not shown) can be arranged between the wooden building blocks 100 to compensate for possible changes in the dimensions of the exterior wall elements 1a and 1b and / or the interior wall element 2 and to prevent moisture penetration. Such changes can occur even though the exterior wall elements 1a and 1b and the interior wall element 2a already meet high quality standards by being made of solid kiln-dried wood.

[0061] The three views according to Fig. 2a, 2b and 2cshow overview representations of a wooden building block 100 with two outer wall elements 1a and 1b and two first inner wall elements 2a, 2b and a second inner wall element 3. This embodiment thus has a total of five wall elements, of which the first inner wall elements 2a and 2b are offset upwards and to the right in a wall. This arrangement of the first inner wall elements 2a and 2b results in the first inner wall elements 2a and 2b protruding above the outer wall elements 1a and 1b and the second inner wall element 3 and forming the two longitudinal tongues 4a', 4b', as well as protruding to the right and forming the two transverse tongues 4a, 4b. In this embodiment, the grooves 5a, 5b, 5a', 5b' are also formed opposite the tongues 4a, 4b, 4a', 4b'.

[0062] The two exterior wall elements 1a and 1b each have two parallel transverse sides 7a, 7b and two parallel longitudinal sides 7c, 7d. The longitudinal sides extend in a longitudinal direction L. The transverse sides 7a, 7b and the longitudinal sides 7c, 7d preferably run perpendicular to each other, so that the exterior wall elements 1a and 1b are each designed as rectangular panels, each with an inner side surface 10a and an outer side surface 10b with a rectangular cross-section Q 10 .

[0063] The first inner wall elements 2a and 2b each have two parallel transverse sides 8a, 8b and two parallel longitudinal sides 8c, 8d. The longitudinal sides 8c, 8d extend in the longitudinal direction L. The transverse sides 8a, 8b and the longitudinal sides 8c, 8d preferably run perpendicular to each other, so that the first inner wall elements 2a and 2b are designed as a rectangular plate with two side surfaces 11a, 11b facing the outer wall elements 1a, 1b and having a rectangular cross-section Q 11 .

[0064] In the embodiment shown, the length of the transverse sides 7a, 7b of the outer wall elements corresponds to the length of the transverse sides 8a, 8b of the inner wall element 2 and the length of the longitudinal sides 7c, 7d of the outer wall elements corresponds to the length of the longitudinal sides 8c, 8d of the inner wall element 2, so that the cross sections Q 10 and Q 11 correspond.

[0065] The second inner wall element 3 has two parallel transverse sides 9a, 9b and two parallel longitudinal sides 9c, 9d. The longitudinal sides extend in the longitudinal direction L. The transverse sides 8a, 8b and the longitudinal sides 8c, 8d preferably run perpendicular to each other, so that the inner wall element 2 is designed as a rectangular panel.

[0066] 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.

[0067] The three views according to Fig. 3a, 3b and 3c Now show further overviews of a wooden building block 100. For the same and similar parts of the wooden building block, the same reference numerals were used, as in the previously shown embodiments according to the Figures 1a to 1cand 2a to 2c. Reference is also made to their description.

[0068] In the overview illustrations shown, the wooden building block 100 has two exterior wall elements 1a and 1b and five interior wall elements 2a, 2b, 2c, 3a, and 3b. This design variant thus has a total of seven wall elements, of which the first interior wall elements 2a, 2b, and 2c are offset upwards and to the right within a wall. This arrangement of the first interior wall elements 2a, 2b, and 2c results in the first interior wall elements 2a, 2b, and 2c projecting above the exterior wall elements 1a and 1b and the second interior wall elements 3a and 3b, forming the three longitudinal tongues 4a', 4b', 4c', and protruding to the right and forming the three transverse tongues 4a, 4b, 4c. In this embodiment, the grooves 5a, 5b, 5c, 5a', 5b', 5c' are also formed opposite the springs 4a, 4b, 4c, 4a', 4b', 4c'.

[0069] The second inner wall elements 3a and 3b, i.e. their transverse sides 9a, 9b and longitudinal sides 9c, 9d, are arranged parallel to the outer wall elements 1a and 1b, i.e. their transverse sides 7a, 7b and longitudinal sides 7c, 7d.

[0070] The three views according to Fig. 4a, 4b and 4c Now show further overviews of a wooden building block 100. For the same and similar parts of the wooden building block, the same reference numerals were used, as in the previously shown embodiments according to the Figures 1a to 1c as well as 2a to 2c and 3a to 3c. Reference is also made to their description.

[0071] The three views according to Fig. 4a, 4b and 4c The overviews shown essentially correspond to the representations of the Fig. 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 longitudinal side 7c designed as an outwardly sloping slope 12.

[0072] The slope 12 allows moisture to drain away and prevent it from penetrating the interior of the wooden block 100. This ensures high weather resistance.

[0073] The kit for producing a wooden building block 100 is not explicitly shown in the figures, but is readily apparent to the expert, among other things, from the Fig. 1a to 4c and the description is obvious and understandable.

[0074] The individual production of a wooden building block from such a kit is carried out by assembling two exterior wall elements 1a, 1b with at least one interior wall element 2a, 2b, 2c, 3a, 3b, wherein the exterior wall elements 1a, 1b and the interior wall elements 2a, 2b, 2c, 3a, 3b preferably have prefabricated holes for connecting elements. The holes are arranged such that selected first interior wall elements 2a, 2b, 2c are positioned offset in the vertical and horizontal directions relative to the exterior wall elements 1a, 1b in the installed state in a wall by inserting the connecting elements such that opposite each other, pairs of transverse grooves 5a, 5b, 5c and tongues 4a, 4b, 4c and longitudinal grooves 5a', 5b', 5c' and tongues 4a', 4b', 4c' are formed.

[0075] In this example, the connecting elements are screws and / or wooden dowels.

[0076] The four views according to Fig. 5a, 5b , 5c and 5d Now show further overviews of a wooden building block 100. For the same and similar parts of the wooden building block, the same reference numerals were used, as in the previously shown embodiments according to the Figures 1a to 1c , 2a to 2c as well as 3a to 3c and 4a to 4c used. Reference is also made to their description.

[0077] The four views according to Fig. 5a, 5b , 5c and 5d now show two wooden blocks 100, 100' each having a front corner connection 13.

[0078] Each of the two corner connections 13 is formed in the present case by a number of second transverse sides 7b, 8b, 9b of the two first interior wall elements 2a, 2b, the second interior wall element 3, and the two exterior wall elements 1a, 1b. At least a portion of the second transverse sides 7b, 8b, 9b is arranged offset from one another in a stepped manner, starting from the first exterior wall element 1a and moving toward the second exterior wall element 1b. The corner connections 13 of the two wooden building blocks 100, 100' are configured 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'.

[0079] In this case, 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 two first interior wall elements 2a, 2b are set back from the first transverse sides 7a, 9a of the second interior wall element 3 and the two exterior wall elements 1a, 1b.

[0080] The first interior wall elements 2a, 2b are arranged in a known manner with a horizontal offset V h and a vertical offset V v - with respect to the arrangement of the wooden block in a wall - offset from the exterior wall elements 1a, 1b and the second interior wall element 3.

[0081] The longitudinal sides 8c of the two first inner wall elements 2a, 2b protrude relative to the longitudinal sides 7c of the two outer wall elements and the second inner wall element 3, are thus arranged offset relative to them, and thus form two longitudinal springs 4a', 4b'.

[0082] The invention is not limited to the means, features, and method steps described in the present embodiment. Rather, it is possible to realize further embodiments by combining and varying the means, features, and method steps mentioned, without departing from the scope of the invention defined by the patent claims.
