Description

FIELD OF THE INVENTION

The present invention relates to a wooden construction in log construction, in particular a log house or a raised bed. The present invention further relates to a pre-assembled wooden plank segment.

TECHNICAL BACKGROUND

There are various types of log construction. A log house or log cabin is a wooden building constructed using log construction with walls made of overlapping, raw or processed logs or planks. Log houses of this type are well known, so the construction does not need to be explained in more detail.

When building a log cabin, the individual wooden planks must be connected to one another in order to create a statically stable structure. For this purpose, connecting elements are used, which are designed as milled dovetail tenons, for example.

Furthermore, smaller wooden structures can also be built using log construction, such as raised beds, climbing frames for children or even sandpits.

SUMMARY OF THE INVENTION

The present invention is based on the object of simplifying the production of a wooden construction in block construction and, in particular, making it more flexible.

According to the invention, this object is achieved by a wooden construction having the features of patent claim 1 and by a pre-assembled wooden plank segment having the features of patent claim 2.

Accordingly, it is envisaged:

• - A wooden construction in log construction, in particular a log house or raised bed, with walls that have wooden planks made of solid wood, wherein the respective wooden plank has a connecting area on at least one of the end faces, which is designed to connect the respective wooden plank to at least one other wooden plank or a connecting element, wherein a connecting area is designed as a recess provided in the respective end face with a dovetail geometry, and with a plurality of block connectors, wherein a respective block connector has a double dovetail geometry that is designed and dimensioned in such a way to connect two wooden planks to one another in a form-fitting and force-fitting manner via their connecting areas or to connect a wooden plank to a connecting element in a form-fitting and force-fitting manner via their connecting areas.
• - A pre-assembled wooden plank segment for a wooden construction, in particular for a wooden construction according to the invention, with at least one wooden plank made of solid wood, wherein at least one wooden plank has a connecting region on at least one of its end faces, which is designed to connect the respective wooden plank to at least one other wooden plank or a connecting element, wherein a connecting region is designed as a recess provided in the respective end face with a dovetail geometry, and with at least one block connector, wherein a respective block connector has a double dovetail geometry which is designed and dimensioned in such a way as to connect two wooden planks to one another in a form-fitting and force-fitting manner via their connecting regions or to connect a wooden plank (1) and a connecting element to one another in a form-fitting and force-fitting manner.

The idea underlying the present invention is to create force-fit connections between several wooden planks using additional parts designed as block connectors. The block connectors represent the connecting means for connecting at least two wooden planks to one another.

The idea underlying the present invention further consists in creating force-fitting connections between at least one wooden plank and a connecting element with the aid of additional parts designed as block connectors.

The wooden planks and the at least one connecting element each have at least one connecting area in order to connect the elements to one another via a block connector.

This block connector according to the invention is characterized in that it has the geometry of a double dovetail connection or a double dovetail-like connection. The respective dovetail connection can each have cheeks arranged symmetrically to one another, with two of these dovetail joints can form a double dovetail joint.

Such a double dovetail joint can have a certain X-shape.

The double dovetail connection can, for example, have two symmetrically arranged dovetail connections. The dovetail connections can also be designed differently, in particular asymmetrically.

In another embodiment, another optional part, the so-called fixing or clamping block, can be used to block the springback of the particularly elastic cheeks in order to be able to transmit higher forces.

Preferably, the double dovetail connection has respective V-shaped recesses in each dovetail connection, i.e. in particular in the region of opposite ends, whereby an elastic tolerance compensation of the two cheeks on each side is enabled.

Compared to a well-known block connection, in which, for example, milled dovetail tenons are used on one of the wooden planks to be connected, this complex work step is omitted and can be replaced by a much simpler dovetail recess. This can be milled completely over the entire connection height of the component in a single operation. The block to be connected is processed in the same way. Only a linear milling process is necessary. This also saves material.

In the case of roof trusses, when rafters are fixed to the ridge beam, two elements are connected to one another that are not in one plane, but are arranged at an incline corresponding to the roof pitch and are connected to one another at an angle. Such angled connections can also be implemented with the wooden construction.

It is also possible to create a type of plug-in system. Prefabricated block connectors with two, three or more recesses can be plugged together with prefabricated wooden planks produced in different lengths. This can be used to make small wooden structures such as raised beds, sandpits, small scaffolding or even toys.

Advantageous embodiments and further developments emerge from the further subclaims and from the description with reference to the figures of the drawing.

According to a preferred embodiment, the block connector has a V-shaped recess at its two opposite ends. The V-shaped recess of the cheeks together with the choice of material (i.e. wood) advantageously enables elastic tolerance compensation. Furthermore, the block connector can be clamped in the wooden planks, since the block connector can be mounted with pre-tensioned cheeks in a recess in the respective wooden connector.

According to a further preferred embodiment, the V-shaped recesses are designed such that the block connector has flexible cheeks in the area of the respective V-shaped recess. Flexible means in particular that the cheeks can move towards one another. In particular, the cheeks can also move away from one another, so that bracing in the respective wooden plank is possible.

According to a preferred embodiment, at least one fixing element is provided which is shaped and designed in such a way that it can be inserted into the V-shaped recess between the block connector and the connection area. This blocks flexible cheeks, which prevents the cheeks from springing back. The fixing element is also designed in particular in a V-shape so that it can be inserted into the V-shaped recess. When inserted, the fixing element is in contact with a cheek in particular on two opposite side surfaces, so that force can be transmitted from the cheeks to the fixing element.

According to a preferred embodiment, the fixing element has a central, continuous fixing hole. The fixing hole is designed in particular as a mounting opening. Furthermore, the fixing hole can enable a targeted deformation of the fixing element, whereby a force transmission from the fixing element to the cheeks, and vice versa, can also be controlled.

According to a preferred embodiment, at least one edge of the block connector is chamfered and/or rounded. The edge is in particular an edge that runs along a cheek. According to the invention, the chamfer and/or rounding facilitates the insertion of the block connector into a recess in the wooden planks and thus This simplifies assembly. In particular, the risk of jamming can be reduced. In one possible embodiment, the cheeks can each have a bevel and/or rounding on one edge of an outer side. This means that those edges in particular are touched or rounded that are first in contact with the recess when the block connector is inserted into the recess.

According to a preferred embodiment, the block connector has rounded corners at its two opposite ends, which enable simplified connection or assembly.

According to a preferred embodiment, the wooden planks are made of glued laminated timber, often also referred to as laminated board timber, glued timber, glued beams or in short BS timber or BSH. Glued laminated timber is understood to be wood made of several layers of boards, preferably glued in the same grain direction. They are mainly used in timber engineering, i.e. for static loads. This means that the wooden planks can have any strength, for example, and warping of the wood is less likely. Furthermore, a recess can be easily implemented. Of course, other types of wood are also conceivable, such as solid wood, board stack timber, cross laminated timber, veneer strip lumber and the like.

According to a preferred embodiment, the dovetail recesses, i.e. the recesses with a dovetail shape, which are provided in the wooden planks, are of the same dimensions and in particular are of identical design. This allows a symmetrically designed block connector to be used.

According to a preferred embodiment, the connecting elements, i.e. the block connectors, are of the same dimensions. This allows flexible use of block connectors that are not individually shaped at certain positions. In particular, this allows manufacturing costs to be reduced.

According to a preferred embodiment, the dovetail recesses, i.e. the recesses with a dovetail shape, are milled or sawn out of the material of the wooden plank or the connecting element.

According to a preferred embodiment, the block connectors and the wooden planks are made of the same wood material, in particular the same type of wood. Furthermore, the at least one connecting element can be made of the same wood material, in particular the same type of wood, as the block connector and the wooden planks. Likewise, different materials can be used, for example to increase the strength of the block connectors compared to the wooden planks and/or the connecting element.

According to a preferred embodiment, the width of a base of a connection area is in the range of 1/5 to 1/3 of the width of the wooden plank. In particular, the connection area is provided centrally in the respective wooden plank, wherein the recesses are arranged centrally in the respective wooden plank.

When installed, the block connectors are therefore not visible within the thickness of the wooden planks. This creates the visual impression of a connection without fasteners.

According to a preferred embodiment, the connecting element can have at least one connecting area, which is designed as a recess provided in an end face with a dovetail geometry. The connecting areas of the connecting element and the wooden planks can be shaped identically. In this way, a particularly flexible plug-in system can be implemented, whereby different elements can be connected to one another as desired.

According to a preferred embodiment, the connecting element can have a triangular, square or rectangular cross-section, with corner areas of the cross-section each having a flattened end face, with a recess with a dovetail geometry being formed on each end face. This allows, for example, circumferential recesses to be formed so that wooden planks can be arranged at any angle to the connecting element.

The above embodiments and developments can be combined with one another as desired, provided that this makes sense. Other possible embodiments, developments and implementations of the invention also include combinations of features of the invention described above or below with regard to the exemplary embodiments that are not explicitly mentioned. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

DESCRIPTION OF EMBODIMENTS

1 shows an embodiment of a block connector 5 in an assembled state on two wooden planks 1a, 1b. The block connector 5 has a double dovetail geometry, with a dovetail geometry engaging in a recess 4 in the respective wooden plank 1a, 1b. The block connector 5 is arranged in a connection area 3 between the two wooden planks 1a, 1b and is inserted into a respective recess 4, which is formed on the respective end face 2 of each wooden plank 1a, 1b.

The respective dovetail geometry has two cheeks 7, each of which is formed by a V-shaped recess 6. A fixing element 8 can be subsequently inserted into the V-shaped recess in order to press the cheeks 7 against the outer walls of the recess 4.

Advantageously, the cheeks 7 of each dovetail geometry are widened with respect to the outer walls of the recess 4, so that when they are introduced into the recess 4 they are pressed in or subjected to a pre-stress. This means that the block connector 5 is held in the recesses 4 in a force-fitting manner. Furthermore, this makes it possible, for example, to compensate for existing tolerances caused by the manufacture of the recess 4.

The V-shaped recess can be clamped after the block connector 5 has been set using a subsequently inserted fixing element 8. The fixing element 8 can be designed as a wedge or clamping block with which the cheeks 7 are locked in the recess 4. This means that considerably higher tensile loads can be achieved without making assembly more difficult. The fixing element 8, like the block connector 5, can be made of different materials and its geometry can be adapted to the requirements of the specific application. In addition, the front edges should also be provided with a chamfer in order to to facilitate assembly. An assembly opening 13 is also used for this purpose, to accommodate a suitable auxiliary tool to facilitate the insertion of the clamping block. If the wooden planks are to be loosened again, this assembly opening 13 also offers the possibility of inserting a tool with a thread or extractor (so-called pigtail) in order to remove the fixing element 8 again.

Furthermore, projections 12 can be provided on the fixing element 8, which are also aligned against an outer wall of the recess 4 or can contact it. This can make it easier to insert the fixing element 8 into the recess 4, while at the same time a contact pressure can be generated against another outer wall of the recess 4. Due to the small contact surface of the projections 12, which can be designed as knobs, for example, a high contact pressure can be generated.

The block connector 5 can be designed symmetrically with respect to a vertical axis in the illustration and/or with respect to a horizontal axis, shown as symmetry axis 11h, 11v.

If, for example, the dovetail tenon 15 on the wooden plank 1 is damaged in a conventional construction method, in the worst case scenario the entire wooden plank 1 may no longer be usable (see 1a) However, if instead of using such an outwardly directed dovetail tenon 15 there is only one recess 4 in the block of the wooden plank 1, this type of transport damage can advantageously be reduced and the associated total loss of the wooden planks 1 can be avoided.

Furthermore, by means of the invention, the length of a wooden plank 1 can advantageously be increased by the length of the dovetail tenon 15 used in conventional connection techniques (see 1a) which corresponds to half the length of the block connector 5 aligned in the horizontal direction. This also results in a significant material saving 16 (see 1b and 1c ), which is proportionally most noticeable for short wooden planks 1.

On the vertical axis of symmetry 11v, the block connector 5 can have a width of 1/5 to 1/2 of the width of the wooden plank 1, in particular a width of 1/3 of the width of the wooden plank 1. By selecting the material, the block connector 5 can have a higher strength than the wooden planks 1a, 1b.

Since the block connector is a separate component, various materials can also be used to advantage, such as glued laminated timber (GLT), spruce, larch, oak, alder, etc. Even non-wood materials such as plastics or metallic materials are conceivable. This makes it possible to meet a wide range of requirements such as higher strength, better modulus of elasticity or tolerance compensation through different designs.

2 shows a schematic representation of a block connector 5 in a non-installed starting position, 2 (a) , and with inserted fixing element 8, 2(b) , as well as a state-of-the-art design, 2 (c) .

2 (a) shows the block connector 5 with four flexible cheeks 7. The cheeks 7 are particularly flexible because they are arranged to the right and left of a V-shaped recess 4. This allows the cheeks 7 to be moved towards each other in pairs. The illustration shows that the block connector 5 is symmetrical with respect to a vertical and a horizontal axis. In an embodiment not shown, the two left cheeks 7 and the left V-shaped recess 6 can have a different geometry to the right-hand version.

2 (b) shows the block connector 5, supplemented with two fixing elements 8 pressed in after assembly of the block connector 5. The fixing elements 8 can block the flexible cheeks 7 and thus in particular prevent the cheeks 7 from springing back. This preferably allows a positive and/or non-positive connection to a wooden plank 1 to be achieved.

A mounting opening 13 is provided in each of the fixing elements 8. This can be designed as a hole and serve as an assembly aid. Furthermore or alternatively, the mounting opening 13 can enable a targeted deformation of the fixing element 8, and thus in particular also of the cheeks 7. Furthermore, projections 12 are provided on the fixing elements 8 in order to continue to hold the fixing elements 8 in a recess 4 in the respective wooden plank 1.

The block connector 5 can be designed with rounded corners 10, in particular to facilitate assembly.

2 (c) shows a design from the prior art, wherein the block connector 5' is designed as a solid structural element. Such a block connector could, for example, be provided as a replacement for a milled dovetail tenon that is firmly connected to the wooden planks. Bracing the dovetail shape with However, it is not possible to connect the surrounding wooden planks as it is a solid block.

In 3 is a section of a wooden building in log construction, in particular a section of a log house. The walls are made of solid wood planks 1. The wooden planks 1 are connected at the end faces with block connectors 5. For this purpose, recesses 4 are provided on the end faces, into which the block connectors 5 can be inserted. Two adjacent wooden planks 1 can thus be connected to one another in a form-fitting and force-fitting manner.

The block connectors 5 make it possible for even thinner wooden planks, in particular with a thickness of 10 mm or more, preferably 20 mm to 100 mm, to be connected in a form-fitting manner to much more solid planks.

In solid wood construction, the planks are sometimes offset by half a height, so that the block connector 5 only needs to cover half the plank height of a wooden plank 1 when inserted in the first work step. This requires two block connectors 5 per connection, which can also be slightly shorter in order to compensate for height tolerances.

4 shows block connectors 5 arranged one above the other in this way. It can be seen that a bevel is formed on the edges 9 of the block connector 5. This enables easier insertion into the recesses 4, which simplifies assembly.

The block connector 5 can be manufactured in different lengths and sizes. Preferably, the block connector 5 is manufactured at half the height of the wooden plank 1 in order to avoid higher assembly forces. Using such a block connector 5 with a length of half the height of the wooden plank 1 enables it to be used at different height positions with respect to the wooden planks 1.

In general, the block connector 5 is a geometrically simple component that is ideally suited for mass production; this also applies to the fixing element 8, such as a clamping block in particular. The extremely complex machining of a dovetail connection to a log is thus eliminated and is replaced by a "simple" slot.

In addition to the above-described assembly of the wooden planks 1 using the block connectors 5, other types of assembly would also be conceivable and advantageous. For example, it would be conceivable if one or more wooden planks 1 were pre-assembled using the block connectors 5 to form so-called wooden plank segments 14. This is shown in 5 shown one of the 3 comparable arrangement with a pre-assembled wooden plank segment 14. These pre-assembled wooden plank segments 14 can be designed so that they can be transported efficiently, for example. The pre-assembly of the wooden plank segments 14 is advantageous in that the pre-assembly can be carried out efficiently and easily in the manufacturer's assembly hall, so that only a few assembly steps are required for the final assembly. The final assembly can then usually be carried out with fewer personnel than would be possible without pre-assembly. In addition, fewer special tools may be required.

6 shows another pre-assembled wooden plank segment 14. A block connector 5 is pre-assembled on a wooden plank 1. In such an embodiment, the fixing element 8 can already be inserted into the block connector 5, so that a temporarily non-detachable connection can be created between the block connector 5 and the wooden plank 1.

The block connector 5 can be adapted to the height of the wooden plank 1. Furthermore, the height of the block connector 5 can be shorter than the height of the block connector 1, so that two block connectors 5 can be inserted one above the other in a wooden plank 1, as in 6 shown. This is particularly advantageous when the block connectors 5 are arranged offset in height to the wooden planks 1 in order to further improve the stability of the construction. In particular, this means that two wooden planks 1 arranged one above the other can be connected to one another with just one block connector 5. The block connector 5 is preferably designed with half the height of the wooden planks 1, whereby the assembly forces can be further reduced.

The block connectors 5 can be made in different lengths and sizes adapted to the wooden planks 1 and the connecting elements 17, for example shown in the 9-12 , are manufactured.

7 shows an embodiment of a pre-assembled wooden plank segment 14 on a rafter. The rafter, characterized by the wooden plank 1a, is angled, whereby the angle can be designed according to a roof pitch. Two block connectors 5 are arranged one above the other on an end face of the rafter 1a in order to connect the rafter 1a to the purlin, characterized by the wooden plank 1b. The purlin 1b has a recess 4 on one side surface into which the block connectors 5 can be inserted.

It is therefore also conceivable to create angled structures, for example a roof truss. For example, in gable roofs, pent roofs or hip roofs, the rafters are angled according to the roof pitch. According to the invention, a recess 4 can be made in the rafters parallel to the plane of the purlin. This means that, for example, all block connectors 5 can advantageously be pre-assembled on the purlin 1b before the rafters 1a are inserted. The rafters can then be subsequently aligned before they are finally locked in the final position with the respective fixing element 8. In this way, tolerance errors and assembly errors in particular can be compensated for.

8 shows an embodiment of a pre-assembled block connector 5 on a purlin. In contrast to the illustration in 7 the block connector 5 is pre-mounted on the purlin and not on the rafter.

9 to 11 show embodiments of different connecting elements 17. The connecting element 17 can, for example, have a rectangular or angled cross-section, as in 9 shown, a triangular cross-section, as in 10 or a square cross-section, as in 11 shown. At the respective corner areas, end faces 2 are designed as a flat surface so that recesses 4 can be arranged in the end faces 2.

Such different connecting elements 17 offer the possibility of forming a type of modular system. A large number of standardized components, such as connecting elements 17 as corner connectors or as wall connectors, can therefore be provided in order to form differently shaped wooden structures. The connecting elements 17 can have different lengths. In this way, wooden structures of different heights can also be formed. For example, a log cabin, a bench, a table, a raised bed, a play structure or even smaller huts, such as a dog house or a tool shed, can be built using such a modular system. The wooden planks 1 can be of different thicknesses and heights. This means that walls of different thicknesses and heights can be connected to different geometric connecting elements 17 to form any wooden structure.

12 shows an embodiment of a connecting element 17 with block connector 5 and wooden plank 1, wherein the block connector is, for example, as in 11 In addition, the connecting element 17 can have a hole in the middle so that a fixation for connecting several connecting elements 17 can be introduced one above the other. For example, a pin element 18 with a fixing element 19 can be provided, wherein the pin element 18 can be designed as a threaded rod, bolt or screw, and the fixing element 19 can be designed as a screw nut, spacer, nut or washer, for example.

A shorter design of the connecting elements 17, whereby in a wooden construction several connecting elements 17 are arranged one above the other, makes it possible to simplify the transport of the connecting elements 17 and handling due to a lower weight. For example, the height of the connecting element 17 can be adapted to the height of a wooden plank 1. The block connector 5 can, for example, correspond to half the height of the wooden planks 1 or the connecting element 17. The block connectors 5 can be arranged offset to the wooden planks 1 or the connecting elements 17 in such a way that wooden planks 1 arranged one above the other and connecting elements 17 arranged one above the other are connected with a block connector 5. In this case, an offset arrangement can be implemented similar to masonry, whereby the stability of the wooden construction can be improved by the block connectors 5 alone.

13 shows an arrangement of two connecting elements 17 according to 12 It can be seen that the pin element 18 is longer than the height of the connecting element 17. This allows connecting elements 17 arranged one above the other to be connected to one another via a pin element 18. Fixing elements 19 can be provided for fixing, which are designed as a nut, for example, and in combination with a threaded rod can ensure that the connecting elements 17a, 17b are fixed one above the other.

14 and 15 show a further embodiment of a connecting element 17. In the middle of the connecting element 17 a bore 20 can be seen, into which the elements 18 and 19 as in 12 and 13 shown. The hole can also form a positioning aid in order to arrange connecting elements 17 centrally one above the other. The connecting element 17 is octagonal, with 8 end faces 2 being formed, with a recess 4 being provided on each end face. This means that wooden planks 1 angled to one another at any angle can be attached to the connecting element 17. 14 shows an example, where wooden planks 1Aa, 1b arranged at right angles to each other are connected via block connections the 5 are connected to the connecting element 17. It would also be conceivable to arrange the wooden planks 1a, 1b in 45° angle steps to each other.

As in 14 As shown, the lower connecting element 17a is only half the height of the wooden plank 1b. This allows two connecting elements 17a, 17b to be connected to one another via the wooden plank 1b.

It would also be conceivable to form hexagonal or 10-cornered connecting elements 17, which are comparable to the design in 15 are formed. In particular, a connecting element 17 can have any cross-section, such as a partial circle cross-section or a diamond-shaped cross-section, in order to arrange recesses 4 on end faces 2 that are aligned differently to one another in order to implement a wooden construction with wooden planks 1 that are angled differently to one another.

If sustainable solid wood construction is to be used more frequently for environmental reasons, simplified manufacturing methods must be used more frequently. This would significantly reduce the time required and also enable less qualified workers to work in wood construction. In addition, only uncontaminated, adhesive-free building materials, such as natural wood, can later be used to generate energy without environmentally harmful emissions.

Although the present invention has been fully described above using preferred embodiments, it is not limited thereto but can be modified in many ways.
