Description

Die Erfindung betrifft eine Holzverbindung gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a wood connection according to the preamble of claim 1.

Es sind verschiedene Arten sog. tragender Verbindungen von Holzbautellen bekannt, bei welchen mindestens zwei Holzbauteile, insbesondere Balken oder Träger, mittels einer Verbindungsvorrichtung verbunden sind. Typische Vertreter derartiger Verbindungsvorrichtungen sind Schlitzbleche, Hakenbleche, Balkenschuhe sowie Nut-Feder-artige lösbare Steckverbindung. Dabei handelt es sich jeweils um Metallbauteile.Various types of so-called load-bearing connections of timber construction sites are known, in which at least two timber components, in particular beams or beams, are connected by means of a connecting device. Typical representatives of such connecting devices are slotted plates, hook plates, beam shoes and tongue and groove-like releasable connector. These are each metal components.

An ein Holzbauwerk, insbesondere ein Holzgebäude, werden ebenso wie an andere Bauwerke gewisse Anforderungen hinsichtlich der Brandsicherheit gestellt. Dabei erweisen sich die jeweils verwendeten Holzbauteile als eher unkritisch. Zwar sind die Holzbauteile brennbar, allerdings verringert sich bei einem Brand der tragende Querschnitt der betreffenden Nalzbauteile nur langsam, da das Feuer jeweils die äußere Oberfläche des Holzbauteils abträgt. Zudem ist Holz ein schlechter Wärmeleiter, sodass der innere Querschnitt auch während eines Feuers noch eine gewisse Zeit lang Kräfte aufnehmen kann. Durch diese langsam verringerte Tragfähigkeit, welche durch das verursachende Feuer auch für anwesende Personen nicht unbemerkt erfolgt, kommt es in der Regel bei brennenden Holzbauwerken kaum zu Opfern aufgrund tatsächlich durchgebrannter, und als Folge dessen herunterstürzender Holzbauteile.To a timber structure, especially a wooden building, as well as other structures certain requirements regarding fire safety. In this case, the wooden components used in each case prove to be rather uncritical. Although the wood components are flammable, but in a fire, the load-bearing cross-section of the relevant Nalzbauteile slow only because the fire in each case ablates the outer surface of the timber component. In addition, wood is a poor conductor of heat, so that the inner cross section can take up even during a fire for a certain amount of time forces. Due to this slowly reduced load-bearing capacity, which does not go unnoticed by the causative fire for people present, it usually comes in burning wood structures hardly victims due to actually burned, and as a result of falling wooden components.

Es hat sich jedoch gezeigt, dass die in der Verbindungstechnik zwischenzeitlich üblichen metallischen Verbindungsvorrichtungen einen limitierenden Faktor hinsichtlich der Brandsicherheit von Holzbauwerken darstellen. Die metallischen Verbindungsvorrichtungen sind in der Regel einem Feuer unmittelbar ausgesetzt. Aufgrund der guten Wärmeleitfähigkeit kommt es zu einer schnellen Durchwärmung der metallischen Verbindungsvorrichtungen. Jedoch verringert sich mit zunehmender Temperatur bzw. Wärmeeinwirkung die maximale Belastbarkeit der betreffenden metallischen Verbindungsvorrichtungen zunehmend, und es kommt zu einem plötzlichen Versagen der Verbindungsvorrichtungen. Dabei hat es sich gezeigt, dass in der Regel die metallischen Verbindungsvorrichtungen bereits vor den brennenden Holzbauteilen versagen. Dies erfolgt für die umstehenden und betroffenen Personenkreise in der Regel unerwartet und überraschend, und kann zu Verletzten oder Toten führen. Eine solche Tragfähigkeitsverminderung der Holzverbindung könnte beispielsweise einen herabfallenden Holzbalken, etwa eines Dachstuhles, zur Folge haben.
Die DE 20 2005 016 486 U1 beschreibt eine Fugenabdichltung zwischen Bauelementen mit den Merkmalen des Oberbegriffs des Anspruchs 1, wobei im Bereich einer Fuge zwischen benachbarten Bauteilen ein Material angeordnet ist, welches bei Wärmeeinwirkung aufquillt und die Fuge gegenüber Rauch und Flammen abdichtet.
Aus der US 2006/048466 A1 ist ein Türrahmen bekannt, bei welchem an den Fugen Streifen angebracht sind, welche bei Band bzw. Hitze die Fuge gegen Rauchdurchtritt verschließen sollen.However, it has been shown that the metal connection devices which are meanwhile customary in connection technology represent a limiting factor with regard to the fire safety of timber structures. The metallic connection devices are usually exposed directly to a fire. Due to the good thermal conductivity, there is a rapid heating of the metallic connecting devices. However, with increasing temperature or heat, the maximum load capacity of the respective metallic connection devices decreases increasingly, and there is a sudden failure of the connecting devices. It has been found that, as a rule, the metallic connecting devices already fail before the burning wooden components. This is usually unexpected and surprising for the surrounding and affected groups of people Injured or dead lead. Such a capacity reduction of the wood connection could, for example, a falling wooden beams, such as a roof truss result.
The DE 20 2005 016 486 U1 describes a Fugenabdichltung between components with the features of the preamble of claim 1, wherein in the region of a joint between adjacent components, a material is arranged, which swells when exposed to heat and the joint seals against smoke and flames.
From the US 2006/048466 A1 is a door frame is known in which strips are attached to the joints, which should seal the joint against smoke passage in tape or heat.

Die EP 51 319 A2 offenbart einen Steher, welcher einen Metallkern und mehrere, diesen vollständig umhüllende, Holzteile aufweist. In den Spalten zwischen den Holzteilen sind herkömmliche Dichtungen angeordnet.
Die WO 2005/078 205 A1 beschreibt eine selbstzentrierende Holzverbindung, wobei in den Fugen herkömmliche Dichtungen angeordnet sind.
Aufgabe der Erfindung ist es daher eine Holzverbindung der eingangs genannten Art anzugeben, mit welcher die genannten Nachteile vermieden werden können, mit welcher die Brandbeständigkeit eines Holzbauwerks, insbesondere einer Holzverbindung, verbessert werden kann.
Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht.The EP 51 319 A2 discloses a post having a metal core and a plurality of wooden parts completely enveloping it. In the gaps between the wood parts conventional seals are arranged.
The WO 2005/078205 A1 describes a self-centering wood connection, wherein conventional seals are arranged in the joints.
The object of the invention is therefore to provide a wood connection of the type mentioned, with which the mentioned disadvantages can be avoided, with which the fire resistance of a timber structure, in particular a wood connection, can be improved.
This is achieved by the features of claim 1 according to the invention.

Dadurch kann die Brandbeständigkeit eines Holzbauwerks, insbesondere einer Holzverbindung, verbessert werden. Dadurch kann das vorzeitige Versagen einer Holzverbindung bei Hitze- bzw- Brandeinwirkung verhindert werden. Dadurch kann gezielt der als im Brandfall schwächste Teil einer Holzverbindung erkannte Teil mit geringem Aufwand geschützt werden. Dadurch kann eine hitzebedingte Tragfähigkeitsverminderung der Holzverbindung hinausgezögert bzw. verhindert werden. Dadurch kann die Zeitdauer, welche ein Holzbauwerk als solches während eines Brandes übersteht, ohne zusammenzubrechen, gesteigert werden.As a result, the fire resistance of a timber structure, in particular a wood connection, can be improved. This can prevent the premature failure of a wood connection in the event of heat or fire. As a result, it is possible to protect the part recognized as the weakest part of a wood connection in the event of fire with little effort. As a result, a heat-related capacity reduction of the wood connection can be delayed or prevented. As a result, the period of time which a timber structure as such survives during a fire without collapsing can be increased.

Durch die Maßnahmen der gegenständlichen Erfindung kann die statische bzw. dynamische Tragfähigkeit einer Holzkonstruktion, welche wie vorstehend dargelegt insbesondere ein Fachwerk sein kann, während eines Brandes lange erhalten werden. Dies unterscheidet die gegenständlichen Maßnahmen von Brandschutz- bzw. Rauchgasdichtungen, welche etwa aus dem Bereich des Trockenbaus bekannt sein, und welche lediglich das Durchbrennen eines Feuers von einem Raum in einen benachbarten anderen Raum durch eine nichttragende Trenn- bzw. Zwischenwand verhindern sollen. Die in derartigen Bereichen eingesetzten Element, etwa Leisten, zur Befestigung einer Platte, beispielsweise einer Gipskartonplatte, an einer Wand werden im Sinn der gegenständlichen Erfindung als nichttragend angesehen, da weder die betreffenden Elemente noch die durch diese mit einer Wand verbundenen Platten einen Beitrag zur Standsicherheit eines Bauwerks bzw. Gebäudes leisten. Das betreffende Gebäude ist selbst nach entfernen der betreffenden Teile Standfest und genügt den statischen Anforderungen.By the measures of the subject invention, the static or dynamic load capacity of a wooden structure, which as set out above, in particular a truss can be obtained during a fire long. This distinguishes the objective measures of fire or flue gas seals, which are known for example in the field of dry construction, and which are only intended to prevent the burning of a fire from one room to another adjacent room by a non-supporting partition or intermediate wall. The element used in such areas, such as strips, for attaching a plate, such as a plasterboard, to a wall are considered in the sense of the present invention as non-supporting, since neither the elements in question, or connected by these with a wall plates contribute to stability of a building or building. The building concerned is stable even after removal of the relevant parts and satisfies the static requirements.

Bevorzugt ist vorgesehen, dass die Dichtung 6 die Fuge 5 bei Umgebungstemperaturen unterhalb der Grenztemperatur lediglich bereichsweise ausfüllt. Daher dass die Dichtung 6 bei Umgebungstemperaturen unterhalb der Grenztemperatur die Fuge 5 derart frei lässt, dass nach wie vor ein einfaches Zusammenfügen der beiden Holzbauteile 2, 3 unter Spiel möglich ist, ohne dabei die Dichtung 6 zu beschädigen bzw. an dieser zu reiben. Dadurch kann die Dichtung 6 ebenfalls bereits vor dem endgültigen Zusammenfügen der beiden Holzbauteile im Bereich der Fuge 5 bzw. der zukünftigen Fuge 5 befestigt werden, wodurch ein nachträgliches Befestigen der Dichtung 6, für welches ein Arbeiter etwa auf einer Leiter balancieren müsste, vermieden werden kann.It is preferably provided that the seal 6 fills the joint 5 only partially at ambient temperatures below the limit temperature. Therefore, that the seal 6 at ambient temperatures below the limit temperature leaves the joint 5 so free that still a simple assembly of the two wooden components 2, 3 under play is possible without damaging the seal 6 or rubbing against this. As a result, the seal 6 can also be fastened before the final assembly of the two wooden components in the region of the joint 5 or the future joint 5, whereby a subsequent attachment of the seal 6, for which a worker would have to balance on a ladder, can be avoided ,

In diesem Zusammenhang ist vorgesehen, dass die Dichtung 6 oberhalb der Grenztemperatur ein größeres Volumen aufweist, als unterhalb der Grenztemperatur. Durch die Volumenzunahme kann die Fuge 5 wenigstens bereichsweise ausgefüllt bzw. verschlossen werden. Eine derartige Dichtung 6 kann auch als Heißgasdichtung bezeichnet werden. Ein derartiges Verhalten der Dichtung 6 kann auch als intumeszierend bezeichnet werden.In this context, it is provided that the seal 6 above the limit temperature has a larger volume than below the limit temperature. Due to the increase in volume, the joint 5 can be filled or closed at least in regions. Such a seal 6 may also be referred to as a hot gas seal. Such behavior of the seal 6 may also be referred to as intumescent.

Dabei ist insbesondere vorgesehen, dass die Dichtung 6 oberhalb der Grenztemperatur aufquillt oder aufschäumt.

As a result, the seal 6 has a good thermal insulation capability above the limit temperature.

Bevorzugt ist vorgesehen, dass die Grenztemperatur größer 100° ist, und bevorzugt etwa 130°C bis 200°C beträgt. Dadurch kann erreicht werden, dass die Dichtung 6 bereits die Fuge verschlossen hat, bevor das umgebende Holz selbst Feuer fängt, und bereits bevor wärmebedingte Tragfähigkeitsverminderung an der Verbindungsvorrichtung 4 auftreten. Die Grenztemperatur kann dabei als Starttemperatur angesehen werden, daher als Temperatur bei deren Überschreiten eine Volumenerweiterung der Dichtung 6 beginnt.It is preferably provided that the limit temperature is greater than 100 °, and preferably about 130 ° C to 200 ° C. As a result, it can be achieved that the seal 6 has already closed the joint before the surrounding wood itself catches fire, and even before heat-related load-bearing reduction occurs at the connection device 4. The limit temperature can be regarded as a starting temperature, therefore, as a temperature at which exceeds a volume expansion of the seal 6 begins.

Derartige Dichtungen 6 weisen einen unter Wärmeeinwirkung expandierenden Werkstoff, etwa Blähgraphit, einen Flammhemmer, etwa Alkyldiaminphosphat oder roten Phosphor, und in der Regel noch weitere Komponenten wie etwa Bindemittel und/oder Mineralfasern und/oder weitere Bläh- bzw. Schäummittel auf.Such gaskets 6 have a material which expands under the action of heat, such as expandable graphite, a flame retardant, such as alkyldiamine phosphate or red phosphorus, and generally further components such as binders and / or mineral fibers and / or further expanding or foaming agents.

Es kann auch vorgesehen sein, dass die Dichtung 6 an der wenigstens einen Verbindungsvorrichtung 4 angeordnet ist. Fig. 2 zeigt eine zweite bevorzugte Ausführungsform der gegenständlichen Erfindung, wobei die Verbindungsvorrichtung 4 als Nut-Feder-artigen lösbaren Steckverbindung 8 ausgebildet ist, und wobei die Dichtung 6 seitlich an einem Teil der Verbindungsvorrichtung befestigt ist. dabei kann es vorgesehen sein, den betreffenden Teil der Verbindungsvorrichtung 4 im Wesentlichen vollständig zum ummanteln.It can also be provided that the seal 6 is arranged on the at least one connecting device 4. Fig. 2 shows a second preferred embodiment of the subject invention, wherein the connecting device 4 is formed as a tongue and groove-like releasable connector 8, and wherein the seal 6 is laterally attached to a part of the connecting device. In this case, it may be provided that the relevant part of the connecting device 4 is substantially completely sheathed.

Es kann dabei auch vorgesehen sein, mehrere Dichtungen 6 im Bereich der Fuge 5 anzuordnen. Weiters kann vorgesehen sein, zusätzlich weitere Bereiche bzw. Teile der Holzverbindung 1 mit einer entsprechenden Dichtung 6 zu versehen. Bevorzugt ist etwa bei Ausbildung der Verbindungsvorrichtung 4 als Schlitzblech 7 vorgesehen, die aus dem zweiten Holzbauteil 3 vorragenden Teile der verwendeten Metalldübel mit einer entsprechenden Dichtung zu verkleiden bzw. zu umhüllen, ebenso wie die von außen zugänglichen Teile des Schlitzbleches 7 im zweiten Holzbauteil 3.It can also be provided to arrange a plurality of seals 6 in the region of the joint 5. Furthermore, it can be provided to additionally provide additional areas or parts of the wood connection 1 with a corresponding seal 6. Preferably, when training the connecting device 4 as a slotted plate 7 is preferably provided to disguise or wrap the projecting from the second wooden member 3 parts of the metal dowels used with a corresponding seal, as well as the externally accessible parts of the slotted plate 7 in the second wooden component. 3

Bevorzugt ist vorgesehen, dass die Dichtung 6 als, vorzugsweise selbstklebendes, Dichtungsband ausgebildet ist, wodurch eine einfache Befestigung desselben im Bereich der Fuge 5 unterstützt wird. Es kann aber auch vorgesehen sein, die Dichtung 6 mittels mechanischer Befestigungsmittel an dem ersten oder zweiten Holzbauteil zu befestigen.It is preferably provided that the seal 6 is formed as, preferably self-adhesive, sealing tape, whereby a simple attachment of the same in the region of the joint 5 is supported.
