[0047] FIG. 10 shows several arrangement positions in a schematic illustration based on a building.

[0048] FIG. 1a and 1b show a timber construction joint according to the prior art in cross-section and in oblique projection. A projecting timber component 3 is connected to a building element 5 by the projecting timber component 3 penetrating into the building element 5. In FIGS. 1a and 1b, air flows are indicated by arrows. An air flow impinging on the joint between the timber component 3 and the building element 5 can enter into the interior of the building due to the lack of an airtight plane.

[0049] FIG. 2 shows a timber construction joint according to the invention. For reasons of clarity, the connection system 1 is shown without timber component 3 and building element 5 (see also FIGS. 5 and 6), and it has a first holding section 13 for the building element 5 and a second holding section 14 for the timber component 3. In the middle, the actual coupling element 15 is shown, which releasably connects the first holding section 13 to the second holding section 14. For this purpose, the second holding section 14 is attached to the first holding section 13 by means of coupling screws 23.

[0050] The second holding section 14 has a timber-component-side fitting 20 with a first contact surface 30 for attachment to a first surface of the timber component 3. For this purpose, the timber component 3 is applied to the contact surface 30 and fixed via fasteners 40. Furthermore, the timber-component-side second holding section 14 has a second contact surface 31 for a second surface of the timber component 3. At this point, the timber component 3 lies against the second contact surface 31 and thus provides for a dissipation of force into the coupling element 15 toward the first holding section 13.

[0051] The first contact surface 30 of the timber-component-side fitting 20 and the second contact surface 31 of the second holding section are located at an angle a relative to each other (shown here with =90), which is adapted to the flux of force and the timber component.

[0052] In the illustrated exemplary embodiment, it is provided that the first holding section 13 has a building-side fitting 19 with a first contact surface 32 for attachment to a first building-side contact surface 32 of the building element 5. An attachment is effected also on this holding section 13 by means of fasteners 40 (e.g., screws), with the building element 5 being attached at this point.

[0053] Furthermore, the first holding section 13 has a second contact surface 33 for a second building-side surface 33 of the building element 5. Thus, the building element 5 also lies against two surfaces 32, 33 on the connecting element 1, wherein the first contact surface 32 of the building-side fitting 19 and the second contact surface 33 of the first holding section 13 enclose an angle 13 which is adapted according to an optimum flux of force and to the timber component (shown here with =90).

[0054] In the connection system 1 of FIG. 2, the first contact surface 32 of the building-side fitting 19 and also the first contact surface 30 of the timber-component-side fitting 20 lie in one plane. In the exemplary embodiment of FIG. 7, those two contact surfaces 30, 32 are arranged in parallel to each other and exhibit an offset Ah.

[0055] Furthermore, the connection system 1 of FIG. 2 has an arrangement of the second contact surface 31 of the second holding section 14 and of the second contact surface 33 of the first holding section 13 which is parallel at a distance D. It would thus be possible to introduce a thermal insulation element 7 between the two holding sections 13, 14 in the area of the coupling element 15.

[0056] The timber component 3 and the building element 5 are connected to the connection system 1 with several fasteners 40. For this purpose, in particular pin-shaped fasteners 40 such as screws (as illustrated), nails, bolts and clamps, but also planar fasteners 40 such as epoxy resin glue or the like come into consideration. If pin-shaped fasteners 40 are used, the respective fitting 19, 20 has fastener guides 41 so that they can be introduced at angles , relative to the respective contact surface 30, 32 and, respectively, 31, 32 of the fitting 19, 20 which have been adapted to the required load-bearing and stiffness behaviour. Herein, the angles , are shown, in each case, with approximately 45.

[0057] In the area of the coupling element 15, an adjusting device 26 is provided. By means of said device, the angle of inclination can be adjusted between the legs 22a, 22b of the coupling element 15. If the angles and (as illustrated in FIG. 2 in contrast to FIG. 3) enclose an angle of 90, the first contact surface 33 of the first holding section 13 is located in the same plane as the first leg 23a, and the contact surface 31 of the second holding section 14 is located in the same plane as the second leg 23b of the coupling element. In most cases, the angle of inclination 0 is 0 for common fields of application (parallel arrangement of the legs 23a, 23b of the coupling element 15), but may also differ therefrom as a result of the load or the structure. With the adjusting device 26, this angle of inclination c can be adjusted to the desired value. For example, an inclination can thus be levelled out so as to rearrange the contact surfaces 31 and 33 in parallel, or a desired inclination could be introduced if the timber component is designed, for example, as a canopy (FIG. 10, bottom right) and an angle of inclination other than 0 is desired.

[0058] In the illustrated exemplary embodiment, the adjusting device 26 comprises an adjusting element 27 by means which a distance d between the first holding section 13 and the second holding section 14 is variable. As a result, the angle between the legs 23a, 23b of the coupling element 15 can be adjusted. Thereby, the inclination of the legs 22a, 22b arranged relative to each other in U-shape is changed.

[0059] In the installed state, the timber component 3 is spaced apart from the building element 5 by a distance D so that a thermal insulation element 7 and/or a different front element 8such as, for example, a plaster layer or fire protection boardscan be introduced between the timber component 3 and the building element 5.

[0060] Furthermore, the stiffening element 29 can be seen, which serves for a better flux of force between the two holding sections 13, 14.

[0061] FIG. 3 shows fluxes of force within the connection system 1 which arise due to the strains on the timber element 3 and, respectively, the building element 5 in order to be able to transfer the bending moment and shear force stresses to the respective holding section 13, 14. Due to the arrangements of the contact surfaces between the fittings 19, 20 and the elements 3, 5 to be connected, which arrangements are adapted to the static stress, the bending moment is divided into several tensile and compressive components F.sub.1, F.sub.2, F.sub.3, whereby several load reserves of the base material are activated. Subsequently, an exclusive bending stress of the holding sections 13, 14 is thereby prevented. The transmission of force between the timber element 3 and the building element 5 is effected by the coupling element 15. Thereby, the bending moment and shear force stresses mainly cause tensile and compressive forces F.sub.1 within the coupling element 15. The tensile force is transferred from the holding section 13 to the holding section 14 by the adjusting element 26, and the compressive force is transferred from the timber component 3 to the building element 5 via the contact surfaces 32 and 33. Depending on the stiffness ratio of the fasteners 40 to the fitting 13, 14, a secondary bending moment is broken down into a force component F.sub.2, F.sub.3, wherein the tensile component is transferred through the fastener(s) 40 and the compressive component is transferred through the contact surfaces 30, 31, 32, 33 into the element to be connected (timber component 3, building element 5).

[0062] FIG. 4 shows an alternative embodiment of the connection system 1. Like components are provided with like reference numerals in all figures so that the figure description of the other figures can be referred to and only differences are described. The illustrated exemplary embodiment has, on the timber-component-side fitting 20, a third contact surface 34 against which the timber component 3 may lie. In addition, the connection system 1 has a wider design so that the stiffening elements 29 are no longer formed only in one plane, but in the shape of pins in two planes. Herein, the releasable attachment is composed of a plug connection (positive engagement) which provides a support 44 so that the timber component 3 can be mounted with the pre-assembled timber-construction-side fitting 20 on the first holding section 13 to the building-side fitting 19 of the building element 5.

[0063] FIG. 5 shows the connection system 1 of FIG. 2 with a timber component 3 and a building element 5 with the intermediate continuous airtight plane formed from an airtightness element 16 in the area of the coupling element 15 and the airtightness layer 17 inherent to the building, as well as the insulation element 7 arranged therebetween, and the attachment of a possible front element 8. In addition, the arrangement of a fire protection element 6 is shown on the bottom side of the coupling element 15.

[0064] FIG. 6 shows an embodiment variant of the connection system 1 as in FIG. 2 or 4 with the difference that, in the connection system 1 of FIG. 2, the first contact surface 32 and the second contact surface 33 of the building-side fitting 19 lie in one plane (=180.

[0065] FIG. 7 shows a very similar connection system 1 as in FIG. 2 or 4 with the difference that, in the connection system 1 of FIG. 2, the first contact surface 32 of the building-side fitting 19 and the first contact surface 30 of the timber-component-side fitting 20 lie in one plane, while, in the exemplary embodiment of FIG. 7, those two contact surfaces 30, 32 are arranged in parallel to each other and exhibit an offset h.

[0066] FIG. 8 shows a connection system 1 according to the invention, wherein, in addition to the thermo-technical and air-convective decoupling, the possibility is shown how 9 appropriate improvements of sound insulation can be achieved by means of inserts of impact sound insulation elements 9.

[0067] FIG. 9 shows an articulated adjusting element in three different positions. The adjusting element has a spherical cap 28 and allows the adjustment of the angle of inclination between the building-element-side fitting 19 and the timber-component-side fitting 20 about an axis of rotation A formed by a spherical cap 27.

[0068] FIG. 10 describes a building with connection systems 1 according to the invention, wherein different possible applications are shown. Possibilities of application are, for example, balcony fixtures, false ceiling fixtures, canopy fixtures or roof fixtures.
