Description

The present invention relates to a connection system for connecting a wooden structural element to a building element. The invention further relates to a timber construction connection comprising at least one such connection system. Finally, the invention relates to a building comprising at least one such connection system.

State of the art

In concrete construction, various connection systems for connecting a building to a cantilevered component, which avoid local cold bridges, are well known. The thermal decoupling of the outer shell of the building and the cantilevered component means that an insulation layer can be attached or implemented without interruption.

In timber construction, the formation of cantilevered components causes small local cold bridges due to the relatively poor thermal conductivity of wood, which normally lead to only minor weak points in terms of building physics. With a thermal conductivity of approx. 0.12 W / mK, wood is around a factor of 3 worse than conventional thermal insulation materials, which have an average thermal conductivity of 0.04 W / mK. In buildings with increased thermal requirements (such as passive houses, active houses), the state-of-the-art projections with a passage of the wooden element and an interruption of the insulation level also cause problems in timber construction.

In addition to the requirements for heat or cold protection, there is another, sometimes much greater, weak point in timber construction when projections are made in the prior art. This concerns the formation of a continuous airtight layer in order to prevent undesired local convection of warm, moisture-saturated air from the inside to the outside, in order to avoid the resulting increased entry of moisture into the load-bearing construction elements and the damage that is usually associated with it. Since there are system-related joints and joints in constructions made of wood, in particular cross laminated timber (CLT or CLT), the risk of increased air convection in the area of the element joints but also in the area of the lamella joints of the individual elements is particularly high. This can only be reduced by increasing the workload through subsequent sealing and / or gluing.

Another problem in timber construction is the exposure of projecting components to the weather, especially during the construction and assembly phase. Even if the cantilevered components are sealed in accordance with the rules, various factors (e.g. direct ventilation) can damage the wooden component. To make matters worse, in the event of damage, cantilevered components that run through from the inside of the building to the outside can only be replaced with considerable effort or, as a rule, can only be reassembled as independent components, which means that separate load transfer structures are required.

DE 88 03 937 U1 discloses a connection system for connecting a wooden structural element to a reinforced concrete ceiling. U.S. 8,896,441 discloses a connection system for connecting a wooden structural element to a building element with a coupling element for pivoting the wooden structural element relative to the building element.

DE 10 2008 061 009 A1 discloses a connection system according to the preamble of claim 1.

Brief description of the invention

The object of the present invention is to provide a connection system for timber construction which addresses the problems mentioned above. In particular, the problem of increased air convection, the interchangeability of the cantilever components, and the thermal decoupling of the cantilever component should be solved.

This object is achieved by a connection system for connecting a wooden construction element to a building element according to claim 1, characterized by a first holding section for the building element, a second holding section for the wooden construction element, a coupling element which releasably connects the first holding section and the second holding section to one another, wherein the second holding section has (i) a fitting on the wood component side with a first contact surface for attachment to a first surface of the wood component and (ii) a second contact surface for a second surface of the wood component, the first contact surface of the fitting on the wood component side and the second contact surface of the second holding section enclose an angle α different from 180 ° with one another.

The building element is preferably also a wooden construction element, for example a floor ceiling.

Such a connection system is on the one hand attached to the building, such as a floor ceiling, via the first holding section, preferably via a fitting on the building side. On the other hand, the wooden structural element, such as a balcony or balcony support, is fastened via the fitting on the wooden structural element side, so that the building and wooden structural element are connected via the connecting element. The connection is a detachable connection. This means that the connection of the two holding sections can be released without one of the holding sections being destroyed, for example via a screw connection, rivets or the like.

Such a connection system makes it possible for the fitting on the building side to be initially attached to the building with an airtight element. In a further step, the building's own airtight layer is connected to the airtight element, for example by means of gluing.

The airtight layer can have a film and / or thermal and / or acoustic insulation elements that are applied to the building.

The wooden structural element can then be fastened to the building via the wooden structural element-side fitting by connecting the two fittings to one another via the coupling element. The connection between the two fittings is detachable, but also rigid and rigid. In the simplest case, a detachable connection can be a screw connection. Other types of connections are also conceivable, e.g. a hook connection, a form-fitting connection such as a dovetail connection. A rigid connection is one in which the deformations are so small that the force application points experience negligible displacements. At most, such rigid connections comprise damped elastic connections that result from structure-borne sound insulation.

Because two contact surfaces are provided which are arranged at an angle different from 180 ° to one another, the holding section encompasses the wooden component at two contact surfaces, which enables an ideal flow of forces within the connection system.

According to the invention it is provided that the first holding portion (i) a building-side fitting with a first building-side contact surface for attachment to a first surface of the building element and (ii) a second building-side contact surface for a second surface of the building element, the first building-side contact surface of the building-side fitting and the second building-side contact surface of the first holding section enclose an angle β different from 180 ° with one another.

The design variants described so far enable an ideal flow of forces between the elements to be connected. In particular, high bending stresses occur due to the customary slim cross-sectional shapes of the wooden structural element. In that the second holding section has a fitting on the wooden component side with a contact surface for attachment to a first surface of the wooden component and a contact surface for a Having the second surface of the wooden component, these surfaces being arranged at an angle α other than 180 ° to one another, these bending moments can be ideally transferred from the wooden component-side fitting via the coupling element to the building element. This also enables timber construction elements that protrude far.

Even if the first holding section has a building-side fitting with a contact surface for attachment to a first surface of the building element and a contact surface for a second surface of the building element, and if here too the contact surface of the building-side fitting and the other contact surface have an angle β of 180 ° with one another include, these forces can also be ideally transferred.

In one embodiment it can be provided that the angle α and / or the angle β are approximately between 45 ° and 135 °, preferably approximately 90 °. In addition, wooden construction elements are usually manufactured with surfaces arranged at right angles to one another, so that there are also technical production advantages.

It is preferably provided that the first contact surface of the fitting on the building side and the first contact surface of the fitting on the wood component side are arranged essentially parallel to one another or lie essentially in one plane. The variant that the contact surfaces lie approximately in one plane or only have an offset (and thus a parallel arrangement) of less than 100% of the thickness of the wooden construction element has advantages for the transmission of forces.

In one embodiment, the fitting on the building side and the fitting on the wooden component side can be arranged essentially parallel to one another or lie essentially in one plane.

One embodiment variant provides that the second contact surface of the second holding section and the second contact surface of the first holding section are arranged essentially parallel to one another. These two contact surfaces are thus arranged at a distance from one another. This has the advantage that further elements, in particular insulating elements, plaster, fire protection elements or the like, can be introduced into this distance.

It can therefore be provided that, in the installed state, the wooden construction element comes to lie at a distance D from the building element, so that a thermal insulation element and / or another one between the wooden construction element and the building element Facade element - such as a plaster layer or fire protection panels - can be introduced.

Furthermore, it can be provided that the fitting on the building side is designed such that it can be connected to the building element by means of at least one fastening means, and that the fitting on the wooden component side can be connected to the wooden component by means of at least one fastening means. This enables simple assembly of the wooden structural element and the building element. In the simplest case, bores can be provided through which the fastening means can be introduced and introduced into the timber structure or building element. The fastening means can be pin-shaped, e.g. be screws, nails, bolts or the like. However, other types of fastening can also be provided, e.g. Brackets, brackets, glue etc.

It is preferably provided that the respective fitting has guides for - preferably pin-shaped - fastening means, so that the fastening means can be introduced at a defined spatial angle y, δ to the respective contact surface of the fitting. At least some of the guides of the fastener guides can be designed in such a way that, in the installed state, the respective pin-shaped fasteners penetrate the respective component at an angle to the contact surface on the fitting, preferably at a spatial angle y, δ between 30 degrees and 60 degrees ( Fig. 4 ). This is particularly advantageous if wooden construction or building elements are made of cross-laminated timber, as this ensures stable and secure anchoring. Glued laminated timber or unglued timber can also be securely fastened in this way.

In an embodiment variant, an adjusting device is provided with which the angle of inclination ε between the second contact surface of the second holding section and the second building-side contact surface of the first holding section can be adjusted. In this way, load-related or production-related inclinations between the wooden construction element and the building element can be compensated.

Furthermore, it can be provided that the adjusting device has an adjusting element with which a distance d between the first holding section and the second holding section can be changed. In the simplest case, the contact surfaces of the two holding sections arranged parallel to each other form a profile with two legs via the coupling element, e.g. a U or V profile (the orientation of the profile is irrelevant), the leg ends being variable in distance via the adjusting element.

The adjusting device can be fastened at a first connection point on the building-side fitting and at a distance at a second connection point on the wooden component-side fitting, the adjusting device having an adjusting element with which the distance d between the two connection points can be changed.

The adjusting device can also have a joint section with which the angle of inclination ε can be adjusted.

For example, an articulated adjusting element could be provided which has a spherical cap, by means of which at least the angle of inclination between the fitting on the building side and the fitting on the wooden component side can be adjusted about an axis of rotation A formed by means of a spherical cap. Alternatively, the adjusting element can have an adjusting device which has a tension screw, a pressure screw, an eccentric or a combination thereof, which is received by the adjusting element by means of a spherical cap, cylinder segment or the like.

Furthermore, it can be provided that an airtight element is attached to the first holding section, to which the building-side airtight layer is attached, for example by means of gluing.

The connection system can be designed such that the coupling element can be detachably and essentially rigidly connected to the fitting on the building side, the fitting on the wood component side, or both. In this case, the coupling element can be separated from the two fittings. In a preferred embodiment variant, the coupling element is inextricably connected to the fitting on the building side and is releasably and essentially rigidly connected to the fitting on the wooden component side. This variant has the advantage that the fitting on the building side can be fastened to the building on the one hand and the fitting on the wooden component side can be fastened on the other hand to the wooden component, whereupon the two fittings are connected to one another so that the wooden component can be assembled quickly.

The detachable connection of the fitting on the building side and the fitting on the wooden component side can, for example, also take place in such a way that the wooden component is also fastened at the same time. For example, a screw can be provided with which the two fittings are connected to one another, in that the screw is guided through receptacles in the two fittings (for example holes) and is screwed into the wooden component.

In one embodiment, it can be provided that the coupling element and the fitting on the wooden component side have sections that interlock in a form-fitting manner such that at least part of the load transfer from the fitting on the timber component side to the coupling element takes place via this form-fitting.

The coupling element preferably has recesses and a plurality of legs which enable an ideal flow of force. A stiffening element is therefore provided in order to increase the stability of the coupling element. The coupling element has parallel legs, the stiffening element connecting the two legs to one another.

It can be provided that the wooden component-side fitting in the assembled state can be connected to the wooden component in a hanging manner from the wooden component-side fitting.

In one aspect of the invention, a wood construction connection is provided which has a connection system of the aforementioned type, the wood component-side fitting and the building-element-side fitting being connected to the coupling element, a wood construction element which is connected to the wood component-side fitting by means of at least one fastening means, and a building element , which is connected to the building element-side fitting by means of a fastening means.

Figures 1a and 1b show a wood construction connection according to the prior art in cross section and in an oblique view. A cantilevered wooden construction element 3 is connected to a building element 5 in that the cantilevered wooden construction element 3 penetrates the building element 5. In the Figures 1a and 1b air flows are indicated by arrows. An air flow that hits the joint between the wooden structural element 3 and the building element 5 can enter the interior of the building due to the lack of airtight layer.

Fig. 2 shows a timber construction connection according to the invention. For the sake of clarity, the connection system 1 is shown without a wooden structural element 3 and a building element 5 (see also Figures 5 and 6 ) and it has a first holding section 13 for the building element 5 and a second holding section 14 for the wooden construction element 3. In the middle, the actual coupling element 15 is shown, which releasably connects the first holding section 13 and the second holding section 14 to one another. For this purpose, the second holding section 14 is fastened to the first holding section 13 with coupling screws 23.

The second holding section 14 has a fitting 20 on the wood component side with a first contact surface 30 for fastening to a first surface of the wood component 3. For this purpose, the wooden structural element 3 is placed on the contact surface 30 and fixed by means of fastening means 40. Furthermore, the second holding section 14 on the wooden component side has a second contact surface 31 for a second surface of the wooden component 3. The wooden structural element 3 rests against the second contact surface 31 at this point and thus ensures a force dissipation into the coupling element 15 towards the first holding section 13.

The first contact surface 30 of the fitting 20 on the wooden component side and the second contact surface 31 of the second holding section are at an angle α to one another that is adapted to the force flow and the wooden component (shown here as α = 90 °).

In the exemplary embodiment shown, it is provided that the first holding section 13 has a fitting 19 on the building side with a first contact surface 32 for fastening to a first contact surface 32 of the building element 5 on the building side. This holding section 13 is also fastened by means of fastening means 40 (e.g. screws), the building element 5 being fastened at this point.

The first holding section 13 also has a second contact surface 33 for a second building-side surface 33 of the building element 5. The building element 5 thus also rests on two surfaces 32, 33 on the connecting element 1, the first contact surface 32 of the fitting 19 on the building side and the second contact surface 33 of the first Retaining section 13 enclose an angle β which is adapted according to an optimal flow of force and the wooden component (shown here with β = 90 °).

In the connection system 1 of the Fig. 2 The first contact surface 32 of the fitting 19 on the building side and the first contact surface 30 of the fitting 20 on the wood component side lie in one plane. In the embodiment of Fig. 7 these two contact surfaces 30, 32 are arranged parallel to one another and have an offset Δh.

The connection system 1 of Fig. 2 furthermore has an arrangement of the second contact surface 31 of the second holding section 14 and the second contact surface 33 of the first holding section 13 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.

Timber structure 3 and building element 5 are connected to the connection system 1 by several fastening means 40. For this purpose, in particular, pin-shaped fastening means 40 such as screws (shown), nails, bolts, and clips, but also flat fastening means 40 such as epoxy resin adhesive or the like. When using pin-shaped fastening means 40, the respective fitting 19, 20 has fastening means guides 41 so that they can be introduced at angles y, δ to the respective contact surface 30, 32 or 31, 32 of the fitting 19, 20, which are adapted to the required load-bearing and rigidity behavior are. The angles y, δ are shown here at approximately 45 °.

An adjusting device 26 is provided in the area of the coupling element 15. With this, the angle of inclination ε between the legs 22a, 22b of the coupling element 15 can be adjusted. If the angles α and β (as in Fig. 2 in contrast to Fig. 3 ) shown enclose an angle of 90 °, the first contact surface 33 of the first holding portion 13 are in the same plane as the first leg 23a and the contact surface 31 of the second holding portion 14 in the same plane as the second leg 23b of the coupling element. The angle of inclination ε for common areas of application is usually 0 ° (parallel arrangement of the legs 23a, 23b of the coupling element 15), but can also deviate therefrom due to the load or construction. With the adjusting device 26, this angle of inclination ε can be set to the desired value. For example, an inclination can be compensated in order to arrange the contact surfaces 31 and 33 parallel again, or a desired inclination could be introduced if the wooden construction element, for example, as a canopy ( Fig. 10 , bottom right) and an inclination angle ε other than 0 ° is desired.

In the exemplary embodiment shown, the adjusting device 26 has an adjusting element 27 with which a distance d between the first holding section 13 and the second holding section 14 can be changed. As a result, the angle between the legs 23a, 23b of the coupling element 15 can be adjusted. The inclination of the legs 22a, 22b, which are arranged in a U-shape relative to one another, is changed.

In the installed state, the wooden structural element 3 is spaced apart from the building element 5 by a distance D so that a thermal insulation element 7 and / or another facade element 8 - such as a layer of plaster or fire protection panels - can be inserted between the wooden structural element 3 and the building element 5.

The stiffening element 29 for a better flow of force between the two holding sections 13, 14 can also be seen.

Fig. 3 shows power flows within the connection system 1, which arise due to the loads on the wooden element 3 or the building element 5, bending moment and transverse forces on the respective holding section 13, 14 to be able to transmit. Due to the arrangement of the contact surfaces between the fittings 19, 20 and the elements 3, 5 to be connected, the bending moment is divided into several tensile and compression components F ₁ , F ₂ , F ₃ , which activates several load-bearing reserves of the base material . As a result, an exclusive bending stress on the holding sections 13, 14 is prevented. The power transmission between the wooden element 3 and the building element 5 takes place through the coupling element 15. The bending moment and transverse force loads mainly cause tensile and compressive forces F ₁ in 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 transmitted from the wooden construction element 3 to the building element 5 via the contact surfaces 32 and 33. Depending on the stiffness ratio of the fastening means 40 to the fitting 13, 14, a secondary bending moment is broken down into a force component F ₂ , F ₃ , the tensile component through the fastening means 40 and the pressure component through the contact surfaces 30, 31, 32, 33 in the element to be connected (wooden construction element 3, building element 5) are transferred.

Fig. 4 shows an alternative embodiment of the connection system 1. The same components are provided with the same reference symbols in all figures, so that the Figure description of the other figures may be referenced and only the differences are described. The exemplary embodiment shown also has a third contact surface 34 on the fitting 20 on the wood component side, against which the wood component 3 can rest. In addition, the connection system 1 is designed to be wider, so that the stiffening elements 29 are no longer designed in just one plane but in the form of pins in two planes. The detachable fastening consists of a plug connection (form fit) which provides a support 44 so that the wooden structural element 3 with the pre-assembled wooden structural fitting 20 on the first holding section 13 can be mounted on the building's fitting 19 of the building element 5.

Fig. 5 FIG. 1 shows the connection system 1 of FIG Fig. 2 with a wooden construction element 3 and a building element 5 with the continuous airtight level in between, formed from an airtightness element 16 in the area of the coupling element 15 and the building's own airtightness layer 17, as well as the insulating element 7 arranged in between, and the attachment of any facade element 8 the arrangement of a fire protection element 6 is shown on the underside of the coupling element 15.

Fig. 6 shows an embodiment variant of the connection system 1 not according to the invention as in FIG Fig. 2 or 4th with the difference that in connection system 1 the Fig. 2 the first contact surface 32 and the second contact surface 33 of the fitting 19 on the building side lie in one plane (β = 180 °).

Fig. 7 shows a very similar connection system 1 as in FIG Fig. 2 or 4th with the difference that in connection system 1 the Fig. 2 the first contact surface 32 of the fitting 19 on the building side and the first contact surface 30 of the fitting 20 on the wood component side lie in one plane, while in the embodiment of FIG Fig. 7 these two contact surfaces 30, 32 are arranged parallel to one another and have an offset Δh.

Fig. 8 shows a connection system 1 according to the invention, in which, in addition to the thermal and air convective decoupling, the possibility is shown how corresponding improvements in sound insulation can be achieved by means of inserts of structure-borne sound insulation elements 9.

Fig. 9 shows an articulated actuator in three different positions. The adjusting element has a spherical cap 28 and enables the angle of inclination to be adjusted between the fitting 19 on the building element side and the fitting 20 on the wood construction element side about an axis of rotation A formed by means of a spherical cap 27.

Fig. 10 describes a building with connection systems 1 according to the invention, with different possible uses being shown. Possibilities for the application are, for example, balcony fastenings, false ceiling fastenings, canopy fastenings or roof fastenings.
