Definitions

  • the present invention relates to a wooden component and a tongue and groove connection according to the preambles of claims 1 and 19.
  • Prefabricated houses made of wood are becoming increasingly important.
  • this material is characterized by an excellent ecological balance during construction and good thermal insulation when used later.
  • wooden buildings offer a high quality of living, especially a pleasant indoor climate.
  • this design enables efficient prefabrication of wall and ceiling elements. Accordingly, ecologically advantageous constructions can be created efficiently and cost-effectively in a fast construction process.
  • the DE 20 2010 001 408 U1 describes a wooden building board for ceilings, walls or roofs and with a lower belt plate extending in the longitudinal direction of the wooden building board and one to it parallel upper belt plate.
  • the two belt plates can be joined together spaced apart by a plurality of webs.
  • the WO 2007/068267 A1 describes a wooden building element for building walls.
  • This wooden component has two support plates and a row of several identical supports arranged between them, which keep the plates at a distance from one another.
  • the chambers formed are at least partially filled with insulating materials.
  • the CH 270 480 describes a component composed of at least two panels which are arranged at a distance and are connected to one another by transverse webs.
  • the panels and webs are connected to one another by pins, the pins being worked out on the webs and engaging in corresponding recesses in the panels.
  • the WO 2009/101203 A1 describes a modular construction system for the formation of walls from several individual elements.
  • the individual elements can be joined together horizontally and vertically and they comprise inner and outer wall sections which are arranged parallel to one another. These wall sections are connected to each other by right-angled struts.
  • the wooden component should be able to perform a number of other functions such as heat insulation, heat storage, heat exchange, moisture buffer, fire protection, sound insulation and sound absorption. Constructions created with this should also be simple be mountable. In particular, both an assembly of individual parts on the building and a pre-assembly of larger elements in the factory should be made possible. For the manufacture of the wooden component, solid wood or wooden materials in the types of wood common for construction should be suitable. In addition, either a shell or a noble shell should be possible.
  • Such a wooden component in particular a wooden support, comprises a pair of opposing, in particular elongated, straps and at least one web arranged between the straps that connects the straps to one another.
  • the web has in each case at least one projection in areas lying on the belts, which engages in a recess on the respective belt.
  • a multifunctional wooden component or a wooden support, is created, which is suitable for both wall and ceiling and roof structures.
  • the wooden component can be manufactured easily, in particular without the use of connecting means such as screws or adhesive connections.
  • designs based on this feature are characterized by a high load-bearing capacity, in particular good flexural rigidity.
  • the wooden component can be made from different types of wood, in particular from oak, birch, larch, beech, spruce, fir, pine or ash.
  • the straps preferably consist of a softwood, in particular of pine, spruce or fir.
  • the bridges on the other hand, preferably consist of a hardwood, in particular of birch, beech or ash.
  • other softwood or hardwood species also in the form of plywood or chipboard, are also suitable.
  • the depressions into which the projections of the web or webs engage are designed as boreholes, in particular as blind holes. This enables a particularly efficient production of the belts, for example with so-called CNC machines (Computerized Numerical Control). If the recesses are designed as blind holes, the wooden component also has a smooth, continuous surface on the outside.
  • the belts each have a central profile, which is delimited by edge profiles, the edge profiles being connected to the central profile by means of a bung.
  • This modular structure of the belts allows them to be manufactured in a flexible manner but with high efficiency.
  • edge profiles for example, middle profiles of different widths can be used, which enables the simple production of edge profiles of different widths.
  • middle profiles with different properties for example from different types of wood or with different surface textures, can be realized in a rational manner.
  • the belts can be elongated and the middle profile can be delimited on both sides by two longitudinal profiles running in the longitudinal direction.
  • the depressions into which the projections of the web or webs engage can be provided on the edge profiles.
  • the middle profiles can be adjusted with regard to other aspects such as aesthetics or acoustics.
  • the depressions into which the projections of the web or webs engage can be arranged at regular intervals from one another.
  • the belts can be elongated and the depressions, into which the projections of the web or webs engage, can be arranged in at least one line running in the longitudinal direction. This makes it possible to create a modular system for building wooden components that are adapted to the respective purpose.
  • the wooden component can comprise a plurality of webs arranged between the belts.
  • the webs arranged between the belts can be designed as rungs with end regions abutting the belts, the rungs in the end regions each having a projection, in particular exactly one, which engages in a recess on the respective belt.
  • the at least one web can also be elongated and in particular have a plurality of projections which each engage in a recess on the respective belt.
  • the web itself can also absorb bending forces.
  • At least one elongated web arranged between the belts can be aligned in the longitudinal or transverse direction relative to the belts.
  • a longitudinally aligned web also called a band web, increases the bending strength, bending load-bearing capacity and shear stiffness of the wooden component.
  • One in the transverse direction Aligned bridge makes it possible to connect two adjacent wooden components to one another so that they are resistant to bending.
  • the projection on a web which engages in a recess on a belt, has a round cross section.
  • Round protrusions can be easily achieved by turning, especially with rung-shaped bars.
  • Round projections have the advantage that drilling the corresponding recesses on the straps is comparatively easy.
  • the web or the webs can be essentially cuboid.
  • a wall element which comprises a plurality of wooden components of the type described above, the wooden components on the end face, preferably via a tongue and groove connection, in particular a tongue and groove connection as described below, a bung or a finger joint directly or are indirectly connected.
  • a wall element has a higher stability than the prior art, in particular a better flexural strength.
  • a further aspect of the present invention relates to a ceiling element which comprises a plurality of wooden beams as described above, the wooden beams directly on the end face, preferably via a tongue and groove connection, in particular a tongue and groove connection as described below, a bung or a finger joint or indirectly connected to each other.
  • a ceiling element is characterized by a good flexural strength, whereby a high floor load can be achieved.
  • the element is suitable for individual assembly on the building as well as for factory pre-assembly. It goes without saying that the said ceiling element can also be a roof element.
  • the straps can be elongated and connected to one another in the longitudinal direction via a finger joint.
  • the belts can also be connected directly or indirectly to one another in the transverse direction via a tongue and groove connection, in particular a tongue and groove connection as described below, or a bung.
  • the belts can be connected to one another in the transverse direction, if appropriate additionally by means of webs running in the transverse direction. This increases the bending strength of the element through biaxiality, and thus the floor load-bearing capacity of a ceiling construction based on it.
  • the wooden beams can be indirectly connected to one another and intermediate elements can be arranged between the belts.
  • intermediate elements the weight of the ceiling element can be reduced if wooden beams are not continuously required for the required bending strength.
  • a cavity between the belts and, if appropriate, also between the intermediate elements can be filled with a filler material.
  • the filling material can be thermal insulation, heat storage, a moisture buffer, fire protection, sound absorption or sound absorption. This means that the wall or ceiling elements can perform other functions in addition to the supporting function.
  • a secondary support structure in particular a concrete structure, preferably a steel structure, a glass structure or a plastic structure can be arranged in a cavity between the belts and optionally also on or between the intermediate elements.
  • the use of such a secondary support structure significantly increases the stability of the construction.
  • the use of a fire-resistant secondary support structure in the event of a fire can ensure the structural stability of the structure.
  • a spring is divided into two partial springs.
  • the partial springs have a mutually corresponding profile, in particular a tooth profile, which essentially prevents longitudinal movement of the wooden components, but enables compensation for shrinkage or swelling. This is particularly advantageous in the case of wooden components made of solid wood, since, if no shrinkage or swelling compensation is possible, the structure can be damaged.
  • the partial springs can be held, in particular glued, in the grooves in a force-fitting or material-locking manner.
  • the tongue for such a tongue and groove connection can consist not only of solid wood or plywood, but also, for example, of a plastic or an elastomer.
  • a tongue and groove connection can perform a sealing function in addition to the functions described above.
  • FIG. 1 shows the modular structure of wooden components 1 according to the invention.
  • the straps 2 are constructed from identical edge profiles 8, 8 ', into which different center profiles 7 can be inserted.
  • the depressions 6, into which the projections 5 of the webs 3, 3 ', 3 "engage, are designed as circular bores on the edge profiles 8 and 8'.
  • the bores 6 are each in a regular manner on a line L running in the longitudinal direction of the belts 2 Distance d is arranged.
  • the webs 3, 3 ', 3 can be designed as band webs 3, rungs 3' or double webs 3". In all shown embodiments of the webs 3, 3 ', 3 "there are 4 projections in areas lying on the belts 5 available in the form of circular cones.
  • the pins 5 of the webs 3, 3 ', 3 engage in the recesses 6 of the belts 2.
  • the edge profiles 8, 8' are each connected to the central profiles 7 via a bung 18.
  • Figure 2 shows a fully assembled wooden component 1 according to the present invention.
  • the wooden component 1 shown is intended to be used in the longitudinal direction via finger joints 14 and in the transverse direction Tongue and groove connections 13 with other elements of the Construction to be connected, as can be seen for example from Figure 3.
  • different wooden components 1 are connected to one another via intermediate elements 10 and 10 'of different widths via tongue and groove connections 13.
  • Figure 4 shows a fully assembled ceiling element 9 according to the present invention, with part of the upper straps 2 'being omitted from the illustration for better clarity. It can be seen that in addition to the webs 3 running in the longitudinal direction there are also webs 3 '''running in the transverse direction.
  • the wooden beams 1 are directly connected to one another, ie without intermediate elements 10 via tongue and groove connections 13.
  • the webs 3 running in the longitudinal direction and the belts 2, 2 'form cavities 11 which can be filled, for example, with an insulating material.
  • the ceiling element 9 can also perform other functions in addition to its supporting function.
  • Figure 5 illustrates in more detail the end connection of two wooden components or wooden beams 1 via finger joint connections 14.
  • FIG. 6 shows the assembly of a ceiling construction with ceiling elements 9, 9 'according to the invention. It can be seen that ceiling elements 9, 9 'preassembled at the factory can be delivered to a construction site and can be joined together on the long side via a tongue and groove connection 13.
  • Figure 7 shows a further embodiment of a ceiling element 9 according to the invention, which is provided for use with a secondary support structure 12 made of concrete.
  • intermediate elements 10, 10' are arranged in pairs, which are both with the straps 2 and with one another are connected via tongue and groove connections 13.
  • the straps 2, 2 'of the carrier 1 are held together by rungs 3'.
  • the intermediate elements 10, 10 ' are also equipped with rungs 3'.
  • the lower belts 2 and the intermediate elements 10 are equipped with a casing 19, which is composed of boards 20 running in the longitudinal direction.
  • the boards 20 are attached to the ceiling element 9 such that they overlap the tongue and groove connections 13 between the lower belts 2 and the intermediate elements 10, 10 ', or between the intermediate elements 10, 10'.
  • the ceiling element 9 can be delivered to a construction site pre-assembled in a factory and used in a ceiling or roof construction.
  • Figure 8 shows a ceiling element according to Figure 7 , which was provided with a secondary support structure 12 made of concrete.
  • the pouring of the ceiling element 9 with concrete advantageously takes place only after it has been inserted into a ceiling structure in order to avoid transporting the heavy composite structure.
  • this procedure allows the ceiling element 9 to be provided with technical installations such as electricity, water or communication lines before pouring concrete.
  • the secondary support structure 12 is shown without reinforcing bars. It goes without saying, however, that such are usually present.
  • An advantage of the ceiling construction shown is that it maintains its structural integrity compared to a classic wood structure, especially in the event of a fire.

Furthermore, such a construction shows better thermal insulation properties and moisture exchange compared to a classic concrete construction.
