Description

The present invention relates to a modular timber component suitable for forming wall elements for buildings, a wall element with at least one such modular timber component and a building comprising such wall elements.

Wooden houses can be built in solid wood construction, in wood panel construction or in timber frame construction.

In the case of solid wood construction, the walls or the wall elements and often also the ceilings are made of solid wood (three, five or more crosswise glued panels). Due to the disk effect, larger glazing spans can be bridged with these glued panels, without having to additionally install supports or columns. The thermal insulation is mounted on the outer facade in this construction (sometimes also from the inside if the solid wood panel should have no visual quality). Steam brakes are no longer necessary due to the glued plates. Furthermore, these wall elements also do not require stabilizing elements such as, e.g. Wooden stand.

Such plates are, for example, as CLT plates of different manufacturers, for example in the production widths (height in the vertical direction in the erect state) 245 cm, 275 cm and 295 cm and in production lengths (width in the vertical direction in the erect state) of 8.00 m ( Minimum length) to max. 16.00 m available.

In solid wood construction, the cost of construction is higher due to the construction compared to the other two construction methods. Furthermore, a crane is always necessary to set up the building, as the individual solid wood components usually weigh several hundred kilos. Cutting windows and doors creates waste which can not be reused in its entirety, since this design is designed for large elements. Therefore, there are virtually no opportunities to build small parts. Current wood losses when cutting are currently about 10-15%.

The Holztafelbau, also referred to as Holztafelbauweise, is a common timber construction of prefabricated houses. The panels are called the flat, self-supporting wooden structures (comparable to the large panels in concrete construction). They represent the walls of the entire structure including all essential installations, are prefabricated in a factory and then assembled at the construction site.

The wooden panel construction corresponds to the construction principle of timber frame construction, but differs in the degree of prefabrication. The transition from wooden panel construction to timber frame construction is fluid. The wooden panels consist of largely prefabricated, prefabricated elements that are planked on both sides. Depending on the choice of insulating materials, these may already be installed in the compartment or be introduced after installation of the elements on the site.

In the wooden panel construction method, the wood panels are first prefabricated and assembled after delivery to the construction site on the construction site. From the DE 198 34 616 A1 a wooden panel construction is known in which also fasteners in the form of press-cut elements are incorporated into the wooden panels.

The wooden panels are composite structures made of ribs that are covered with nails, staples, screws or glue with different building materials, such as solid wood or wood-based panels.

According to their arrangement in the building as wall, ceiling or roof panels, the individual components and their building materials are meaningfully combined and dimensioned so that they can take supporting, stiffening, raumabschließende and / or building physical functions (eg thermal insulation).

In the wooden panel construction, the spatial structure is modularly composed of individual flat wooden panels.

At the factory, large panels are assembled in building dimensions from individual panels whose sizes are determined by the standard formats of the paneling materials. The large panels are transported to the construction site and can be assembled within a short time to the building.

Timber frame construction (also timber frame construction or timber frame construction) is one of the essential modern timber construction systems. A special form of timber frame construction is the wood panel construction, in which the wall and ceiling elements are already prefabricated in the factory as far as possible.

The wooden frame construction is characterized by the fact that a wooden framework with vertical and horizontal bars takes over the vertical support function and the horizontal stiffening by plate-shaped wall materials, diagonally applied boards or recessed struts takes place (these take over the diagonal forces).

In the timber frame construction, the walls consist of uprights and thresholds and a double-sided planking with various wood materials. For example, the planking can be executed on the inside with an OSB board and on the outside with a DWD board (diffusion-open wall and roof panel). On the DWD plate can then still a plaster base plate (impermeable) or a ventilated wooden formwork are mounted. The thermal insulation takes place in the spaces between the uprights and thresholds and can be performed for example with rock wool or cellulose.

From the FR 2 925 082 A1 Further, a wall assembly of plywood modules of wall height is known, which are bolted together at overlapping vertical edges to build massive walls in the width direction, which absorb all forces acting.

By using OSB boards (or chipboard) as outer layers, there is a risk that formaldehyde, which is often contained in wood glue in a large amount leak out and pollute the environment. In addition, only a small sound insulation is given due to the relatively thin outer walls. Due to construction errors, moisture can penetrate the elements more easily than solid construction, which can cause mold to form in the wall.

For all construction principles, the facade design can be freely chosen. Plasters on external thermal insulation systems, masonry trays, exterior cladding made of wood, plastic or mineral plates are just a few examples.

Nevertheless, timber structures are disadvantageous in that they require a large logistical effort, since the individual elements are relatively bulky and heavy. Accordingly, cranes are required for building construction. This increases the assembly costs and burden the ecological balance of the timber construction method.

The object of the present invention is therefore to provide a timber component suitable for forming wall elements for buildings, a wall element comprising at least one such timber component and a building comprising such wall elements which are easy to handle, have a high load-bearing capacity and with which a building of high quality construction can be realized.

This object is solved by the features of the independent claims. Advantageous developments are specified in the subclaims.

According to the invention, a modular timber component is provided, which is suitable for forming wall elements for buildings and comprises at least two layers. A first layer, which is referred to below as the inner layer, is formed at least from two plate-like elements, and a second layer, which is referred to below as the outer layer, is also formed at least from two plate-like elements. The plate-like elements of the layers are arranged crosswise to each other and connected to each other, wherein the timber component is approximately rectangular and accordingly comprises at least two horizontal and two vertical edges, wherein at least one of the vertical edges, a first connecting means for connecting to a wooden stand is formed and on at least one of the horizontal edges, a second connecting means is designed for connection to a further wooden component.
In the context of the present invention, the term crosswise is understood to mean an approximately orthogonal arrangement of the plate-like elements.

Under a timber stand in the context of the present invention, in particular a solid structural timber (KVH) understood. This is a name for refined building timbers. The combination of letters KVH is a protected product designation for special construction timber with defined quality properties exceeding the requirements of DIN 4074, in accordance with an agreement between the Bund Deutscher Zimmermeister (BDZ) and the monitoring association Konstruktionsvollholz e.V.

A wood component according to the invention can, without taking into account the edge processing, a width in the vertical arrangement of approximately 400 mm to 1400 mm, in particular 600 mm to 1200 mm, particularly preferably 600 mm or 1200 mm, and a height in the vertical Arrangement of about 200 mm to 750 mm, in particular 300 mm, 400 mm, 500 mm or 600 mm.

The weight of a timber component may be at most 60 kg, in particular at most 50 kg.

The inventive Modular timber component differs from known wall elements in that several modular timber components are arranged one above the other and coupled or connected to each other and laterally connected or fastened with a vertical edge on a vertical beam or wooden stand, to form a wall element. Therefore, a timber component on at least one vertical edge on the first connecting means for connection to a wood stand and has at least one horizontal edge of the second connecting means for connecting to another timber component. The advantage is therefore also in the shape, size and weight of a timber component that is much more compact than known wall elements. All occurring forces are reliably absorbed by a carcass constructed from wooden uprights (frame), the load on the individual timber component is comparatively low. As a result, the wood components can also be constructed comparatively easily.

The plate-like elements may preferably be formed of solid wood.

The timber component according to the invention is characterized in that it combines the advantages of the bolt construction and solid wood construction with each other, since the elements are relatively lightweight and compact yet solid. The structure and fixation of the timber components according to the invention is carried out in contrast to solid wood construction with the known from the wooden stand construction wooden stands.

Compared to the bolt construction, the present invention has a much lower adhesive or glue content, which is used to connect the individual layers.

Furthermore, the timber components according to the invention by hand or by one or two people can be set up. Therefore, cranes or the like are not necessarily required on the construction site.

In addition, the timber component according to the invention has a very high load-bearing capacity, as a result of which the components, in particular in comparison with the latch construction, can be made relatively narrow or with a relatively thin wall thickness.

Another advantage of the timber component according to the invention is that the timber component due to the orthogonal composite of the inner layer and the outer layer remains dimensionally stable in terms of wood expansion and dehydration and has no problems with respect to penetrating moisture. This is also due to the massive wall structure and the relatively large proportion of wood.

Due to the massive design of the timber construction elements, a completely or partially constructed building offers a relatively large potential for appreciation, similar to a building constructed using solid wood construction.

A significant advantage of the timber component according to the invention is also that in particular the waste from CLT production, such as sections of windows and doors, can be further utilized. For example, it is possible to form a new timber component from a plurality of such cutouts by joining. In this way, costs and raw materials are conserved and the CO ₂ balance improved.

In particular, the timber component according to the invention may be formed from cross-laminated single-layer plates. In addition, it is envisaged that the adhesive content remains below 1%, which makes the finished construction much more environmentally friendly.

Furthermore, as a rule, three, five or more layers can be provided in order to form the timber component. The layers are arranged alternately orthogonal to each other and connected to each other, wherein the outer of the layers have a directional fiber orientation and form each of the inner layer and the outer layer. The directional fiber orientation is important for an internal balance of forces as the degree of humidity in the plate or element changes.

Furthermore, it can be provided that one or more middle layers are formed as glued double layer with the same direction of fiber. The layers or layers arranged further out are constructed orthogonally as described. In this case, the number of layers of 3, 5, etc. on 4, 6, etc. increase.

The layers may each comprise three or more plate-like elements.

The second connection means may have shape features that are complementarily positively formed along opposite horizontal edges of the timber component, in particular as a kind of tongue and groove connection. A positive connection, in particular by tongue and groove, in particular relates to an inhibition of mutual displacement in the surface normal direction and allows the connection of superimposed wooden components without fasteners, in particular solely by complementary formation of the profiles on the horizontal edges. In the context of this application, a surface normal direction of the timber component is a direction normal to a plane that is stretched or bounded by the horizontal and vertical edges and may correspond, for example, to an outer surface or inner surface of the timber component or may be a midplane located therebetween. As tongue and groove connection is understood in the context of this application, a kind of connection, in which of two abutting edges, the one edge has a longitudinal groove and the other edge in the longitudinal direction - complementary to the longitudinal groove - integrally formed spring. Such a molded spring is also referred to as a bounce to distinguish from a loose spring, which is insertable into two abutting grooves. Other suitable connecting means are described in the following embodiment.

In this way, individual timber components can be connected easily, quickly and inexpensively.

The at least one vertical edge of the timber component may comprise a recess extending over the entire length of an edge, which has an approximately rectangular cross-section and extends from the inner layer to the corresponding edge, so that an approximately L-shaped connecting web as the first connecting means is formed to connect the corresponding edge with a wooden stud bar. Other suitable connecting means are U-shaped recesses or tab-like connecting means, which are preferably integrally formed on the timber component or molded or formed in one piece.

Alternatively, it can also be provided that the recess extends from an outer layer to the corresponding edge, so that an approximately L-shaped connecting web is likewise formed.

The first connection means may be formed on each of opposite vertical edges, and may in particular comprise non-complementary shape features. In the case of the L-shaped connecting web, these shape features are - generally speaking - asymmetrical with respect to a plane-parallel center plane (offset outwards or inwards) and symmetrical with respect to a surface-normal, vertical center plane.

The plate-like elements of a layer can with plate connecting means such. As glue or wood glue, tongue and groove joints or be connected to each other with a finger-jointed connection.

Furthermore, according to the invention a wall element is provided, which is formed from one or more timber components explained above. It is provided that at least the vertical edges of the timber component are connected by means of the L-shaped connecting webs, each with a wooden stud beams.

A wall element may preferably be formed from two, three, four, five or six modular wood components. A corresponding wall usually comprises a plurality of such wall elements.

For connecting the L-shaped connecting webs of the two vertical edges, each with a wooden stud bar, the connecting elements which can be used in the construction of wood, such as nails, screws, clamps, etc., can be provided.

Such wall elements can also extremely simple, efficient and quickly set up by one or two people without special expertise by hand. Therefore wall elements according to the invention are extremely inexpensive formable and usable.

The supporting function of a wall element is taken over, in contrast to solid wood wall elements, both from the timber components and from the corresponding vertical wooden beams (wooden stud beams).

Furthermore, a trained from such wall elements building is provided.

An inventive timber component 1 is provided for forming walls, in particular of building walls ( FIGS. 1 to 5 ).

The timber component 1 according to the present embodiment comprises five layers 2, which are referred to below as the inner layer 3, first intermediate layer 4, second intermediate layer 5, third intermediate layer 6 and outer layer 7.

Each of the layers 2 to 7 is formed of a plurality of plate-like members 8. The plate-like elements are made of solid wood, usually made of softwood species.

In the present embodiment, the outer layer of four horizontally disposed plate-like elements 8 is formed. These are in the region of their abutting edges by means of an adhesive such. B. a wood glue, connected together. Alternatively, the use of an adhesive can also be dispensed with.

The outer layer 7 is also connected to the third intermediate layer 6 by means of a suitable adhesive, such. B. a PU, MF, EPI or wood glue, connected.

The third intermediate layer 6 is formed in the present embodiment of twelve plate-like elements 8.

The plate-like elements 8 of the third intermediate layer 6 are arranged orthogonal or at right angles to the plate-like elements 8 of the outer layer 7.

The abutting edges 9 of the plate-like elements 8 of the third intermediate layer can, as explained above, be connected to one another.

The third intermediate layer 6 is likewise connected to the second intermediate layer 5 by means of a suitable adhesive.

The plate-like elements 8 of the second intermediate layer 5 are arranged orthogonal or at right angles to the plate-like elements 8 of the third intermediate layer 6.

The second intermediate layer 5 is formed analogously to the outer layer 7 of horizontally arranged plate-like elements.

The abutting edges of the second intermediate layer 5 can also be connected to each other by means of an adhesive.

The second intermediate layer 5 is connected to the first intermediate layer 4 again by means of an adhesive.

The plate-like elements 8 of the first intermediate layer 4 are arranged orthogonal or at right angles to the plate-like elements 8 of the second intermediate layer 5.

The first intermediate layer 4 is formed analogously to the third intermediate layer.

The first intermediate layer 4 is connected to the inner layer 3, as the other layers and the entire surface by means of adhesive. The inner layer 3 is formed analogously to the second intermediate layer 5 and the outer layer 7 of four horizontally arranged plate-like elements 8.

The plate-like elements 8 of the inner layer 3 are arranged orthogonal or at right angles to the plate-like elements 8 of the first intermediate layer 4.

Thus, the plate-shaped elements 8 of the layers 2 of the timber component 1 according to the invention are arranged crosswise (locked) to each other and connected to each other.

The timber component 1 according to the invention according to this embodiment is approximately rectangular in shape and accordingly has two vertical edges 10 (side edges) and two horizontal edges 11 (top and bottom edges).

The timber component 1 has a width of about 1.2 m, a depth of about 12 cm and a height of about 40 cm.

Furthermore, according to this embodiment it is provided that the vertical edges 10 have a recess 13 extending in the vertical direction 12 for connection to wooden stud beams 14.

These recesses 13 are formed in a plan view in approximately rectangular, so that at the vertical edges 10 of the timber component 1, an approximately L-shaped connecting web remains 15th

The recess 13 extends from the inner layer 3 via the first intermediate layer 4, the second intermediate layer 5 to approximately one third of the thickness of the third intermediate layer 6.

The recesses 13 or connecting webs 15 generally form a first connecting means for connecting the timber component 1 according to the invention to a vertical upright beam 14 (FIG. Fig. 6 ). In this case, the stand bar 14 is received in the width direction approximately halfway in the recess 13 of the timber component 1, while the Connecting web 15 outside (or possibly inside) rests against the uprights beam 14 and possibly with conventional fasteners (screws, nails, etc.) to the uprights beam 14 can be fastened. Accordingly, generally speaking, the first connection means is asymmetrical (ie offset to the outer surface) with respect to a plane-parallel center plane, and the first connection means formed on opposite vertical edges 10 are symmetrical with respect to a surface-normal vertical center plane, ie, in particular uncomplementary. A surface-parallel plane is defined by the vertical direction 12 and the horizontal direction 18, a surface-normal direction to both directions 12, 18 orthogonal ( FIG. 2 ).

The vertical edge 12 above horizontal edge 11 of the timber component 1 forms a extending in the vertical direction 12, spring-like projection 16 from. This spring-like projection 16 has a height of approximately 2 cm in the vertical direction and a width of approximately 4 cm in a horizontal direction 17.

The timber component 1 has a thickness or a depth in the horizontal direction 18 of 12 cm.

At a lower horizontal edge 11 in the vertical direction 12, a groove-like recess 17 is provided. This groove-like recess 17 has a depth of about 2 cm and a thickness in the horizontal direction 18 of 4 cm.

Two or more such groove-like recesses can also be provided on the horizontal edge, which can be connected to corresponding spring-like projections of a further wooden component.

Generally speaking, the groove-like recesses 17 and spring-like projections 16 form a second connection means on the horizontal edges 11 for connecting a timber component 1 according to the invention with a further timber component 1 according to the invention. The groove-like recesses 17 and spring-like projections 16 are also generally form-fitting features that complement one another in a complementary manner are. In other words, they are asymmetrical to a horizontal surface-normal center plane of the timber component 1 and, in this special case, symmetrical to a surface-parallel (vertical) center plane of the timber component 1. In alternative embodiments, they can also be asymmetrical to the plane-parallel (vertical) center plane of the timber component 1, ie offset complementary to the outside or inside.

Basically, all known connecting means are suitable for the horizontal and vertical edges known for joining two wooden elements, e.g. finger-jointed joints, mortise-tenon and land-wedge joints, zincing and burring, butt joints, tenon joints, sheet joints, comb joints, neck joints, offset joints, jaw joints, wood nail, metal nail, stud or bolt, dowel and spring.

This timber component 1 has a height in the vertical direction of about 38 cm, so that it can be carried by two people.

In the following, a wall element 19 according to the invention will be described. Such a wall element 19 may, for. B. comprise five vertically arranged one above the other timber elements 1.

It is provided that the spring-like projections 16 of a timber component 1 engage in the corresponding groove-like recesses 17 of a timber component 1 arranged above it ( FIG. 10 ). It is also possible that these are connected by means of a suitable adhesive or by means of appropriate nail or screw with this. (Mostly no glue or other fastener is used at this point.)

The wooden construction elements are only screwed to the side of KVH or wooden stand beams.

The recesses 13 of the vertical side edges are provided for receiving timber stud beams 14 ( FIG. 6 ). The corresponding L-shaped connecting webs 17 are connected to the wood stud beams 14 by means of screws or similar fastening means 22 ( FIG. 7 ). Alternatively, for example, wood or metal nails, dowels, glue, etc. can be used as fastening means.

The respective lowest of the timber components 1 sit on a wooden threshold beam 21 ( FIG. 6 ). The wooden threshold bar 21 may have a profiling which is complementary to the spring-like projections 16 (not shown in detail). Alternatively, a rail 23 with a corresponding profiling on the wooden threshold beam 21 may be attached (Figure 9).

The recesses 13 or connecting webs 15 can each be dimensioned so that a wooden stand 14 substantially completely in width, at best with a manufacturing tolerances corresponding (or for aesthetic reasons intentionally wider) gap, is covered by two of each side mounted connecting webs 17. At laterally outer wooden stands 14, which are occupied only by one side with wooden construction elements 1, a corresponding gap can be filled by a side facing 25 ( FIG. 11 ). On a wooden stand 14, which connects two wall elements 19 abutting one another at an angle of 90 °, instead of two lateral blinds, a corner facing 27 can be attached, which extends around the corner ( FIGS. 14, 15 ). Above the wall elements 19 or walls can be completed by upper limit bar 26 ( FIGS. 13, 15, 16 ). For window openings, a window bar 24 may be provided ( FIG. 9 ).

In the manner described above, a building 20 can be constructed from the wall elements 1 according to the invention ( FIGS. 6 . 7-16 ).

It is envisaged that connected to the L-shaped connecting webs 15 wood stud beams 14, e.g. are arranged on horizontally arranged wooden stud beams.

A plate-shaped wooden construction element may, for example, have a width of 1200 mm x 600 mm height x 100 mm thickness and weigh about 34 kg. If the wall thickness is increased from 100 mm to 240 mm, the height can be reduced from 600 mm to 300 mm, so that the modular timber component has approximately a weight of approximately 41 kg per module.

The outer plate-like elements may be arranged horizontally as well as vertically.

In one embodiment, the recess 13 and thus the connecting web 15 may be formed only on one of the vertical edges 10. Such a wooden construction element 1 can be used, for example, for inner walls of the building 20 when it encounters the surface of another wall. There, a smooth vertical edge 10 of the timber component 1 can be used for example in an incorporated in the surface of the other wall groove whose groove width corresponds to the thickness of the timber component 1.

The connecting means (recess 13, connecting web 15, groove-like recess 17, spring-like elevation 16) are advantageously produced by machine and therefore dimensioned reliable and reproducible. A specification by forming the layering of the individual layers 2 can be exploited and reworked, but in principle must not be considered. The profiling can also be trapezoidal, for example, in embodiments, so that an even better tightness between successive timber components 1 can be achieved.

• Leichte Bauweise, bestehend aus Holzbalken 14, 21, 26 und kleinformatigen, standardisierten Holzbauelementen 1, hergestellten aus kreuzverleimten Massivholzplatten 8. Für diese molularen Holzbauelemente 1 wird kein Hebezeug (wie Kran) mehr benötigt. Die einzelnen Elementen haben ein Gewicht, das 50 kg nicht übersteigt.
• Die Verwendungsmöglichkeit ist nicht nur für Neubau, sondern auch für die Renovierungsarbeiten an den schon längst bestehenden Objekten gegeben.
• Die Holzbauelemente 1 können neu hergestellt werden, oder als weitere Verwertung von Verschnitt in der CLT-Produktion auftreten, der nach dem Formatierungsprozess von großformatigen Plattenelementen zurück bleibt.

The innovative idea is that the combination of two well-known building systems, such as deadbolt construction and solid wood construction, creates a new type of construction system that offers a number of advantages thanks to its novel structure:

• Lightweight construction, consisting of wooden beams 14, 21, 26 and small-sized, standardized timber elements 1, made of cross-glued solid wood panels 8. For this type of wooden structural elements 1 no hoist (like crane) is no longer needed. The individual elements have a weight that does not exceed 50 kg.
• The possibility of use is given not only for new construction, but also for the renovation work on the already existing objects.
• The timber components 1 can be newly manufactured, or occur as further recovery of waste in the CLT production, which remains after the formatting process of large-sized plate elements.

The new building system consists of grid-vertically mounted KVH beams with arranged and as solid wood filling successively mounted timber components 1, each of which is laterally attached to KVH beams 14 (eg., Screwed). For this purpose, the blocks have vertically attached cutouts 13, which form mirror-symmetrical L-shaped connecting webs 15 through the center of the component.

The connection between successive patch timber components 1 consists only by attached, matching (eg, groove, - and spring) profiles.

The differences from the known construction methods also consist in the fact that typical for the bar or carcass construction typical, horizontally arranged KVH profiles, cover plates and insulation layers placed inside are eliminated, all this is replaced only by between wooden elements 1 attached.

The difference from known solid wood construction is also that all vertical connections between timber elements 1 consist only of KVH profiles, which are vertically arranged between timber elements 1 in the grid.

Both types of construction (transom construction and solid wood construction) are known to determine the considerably better load-bearing properties of solid wood construction.

However, by vertically mounted KVH profiles of the total cross-section of vertically arranged slats in the overall construction (KVH plus vertical slats in timber components 1) can be increased, and thus can the already well-known good load transfer surface (from solid wood panel construction) of vertical forces that affect the finished construction.

This improvement (for taking over vertical forces) can be associated with a loss of diagonal and lateral forces (in horizontal direction we will accordingly have less of bearing surface). However, the fact that these forces occur in much smaller quantities, the remaining load-bearing reserve is still large, so that no significant losses for the carrying capacity of the structure with respect to diagonal and lateral forces will occur.

From this new design creates a new product, namely, for example, made of CLT plate wood components 1, which can also be understood as "solid wood block" (wood tile) and used.
