Description

Die Erfindung betrifft einen einteiligen, im Querschnitt T-förmigen Holzverbinder aus dünnem Blech (gem. DIN 1052 also maximal 4 mm, je nach Festigkeitsanforderungen vorzugsweise 2 - 3 mm) nach dem Oberbegriff des Anspruches 1.The invention relates to a one-piece, cross-sectionally T-shaped wooden connector thin sheet metal (according to DIN 1052 maximum 4 mm, depending on strength requirements preferably 2 - 3 mm) according to the preamble of claim 1.

Aus der DE 296 10 381.0 U1 sind L-förmige sog. Winkelverbinder zum (zumindest im wesentlichen) verdeckten stimseitigen Anschluß eines ersten Holzbalkens an einen querverlaufenden zweiten Holzbalken od.dgl. bekannt, und haben sich an sich auch bestens bewährt.From DE 296 10 381.0 U1 L-shaped so-called angle connectors for (at least in essential) concealed frontal connection of a first wooden beam to one transverse second wooden beam or the like. known, and have in themselves also well proven.

Es hat sich indes gezeigt, daß solche Holzverbinder noch zu verbessern sind, wenn sie außer mit ihrem ersten Befestigungsflansch mit dem anzuschließenden Balken noch mit einer rechtwinklig zum ersten Befestigungsflansch verlaufenden Zuglasche zu verbinden sind, die integraler Bestandteil des Holzverbinders ist, wenn sie also im Querschnitt statt L-förmig T-förmig ausgebildet sind, wobei dann der Schenkel des T den ersten Befestigungsflansch bildet, die eine Steghälfte des T den zweiten Befestigungsflansch, und die andere Steghälfte die vorstehend erörterte Zuglasche, die anschließend auch als "Anschlußflansch" bezeichnet ist.However, it has been shown that such wooden connectors can still be improved if they are not with its first mounting flange with the beam to be connected with another are to be connected at right angles to the first fastening flange An integral part of the wood connector is, if it is T-shaped in cross-section instead of L-shaped are formed, then the leg of the T the first mounting flange forms one web half of the T the second mounting flange, and the other web half the pull tab discussed above, hereinafter also referred to as the "connecting flange" is.

Die Herstellung T-förmiger Holzverbinder ist zwar grundsätzlich nicht schwierig, wenn man sie bspw. aus Strangprofilen mit entsprechendem Profilquerschnitt schneidet. Wenn man sie dagegen aus dünnem Blech fertigt, so ergeben sich ersichtlich Schwierigkeiten, da man unter Festigkeitsgesichtspunkten den Anschlußflansch (Zuglasche) zwar aus relativ dünnem Blechmaterial fertigen könnte, weil er im Einbauzustand im wesentlichen nur durch in seiner Längsrichtung wirkende Zugkräfte beaufschlagt ist, der zweite Befestigungsflansch aber ersichtlich relativ biegesteif sein muß.The production of T-shaped wooden connectors is basically not difficult if you it cuts, for example, from extruded profiles with a corresponding profile cross section. When you see them on the other hand, made of thin sheet metal, there are obviously difficulties, since one under Strength aspects the connection flange (pull tab) from relatively thin Could manufacture sheet metal material because it is essentially only in its installed state Longitudinal acting tensile forces is applied, but the second mounting flange clearly must be relatively rigid.

Da man unter Kosten- bzw. Wirtschaftlichkeitsgesichtspunkten stets bemüht ist, den erforderlichen Materialeinsatz so klein wie möglich zu halten, wird auch bei gattungsgemäßen Holzverbindern eine möglichst geringe Materialstärke angestrebt, die für die jeweiligen Festigkeitsanforderungen (gerade noch) ausreicht, zumal eine Verformung von Blechzuschnitten durch Abkanten, Biegen etc. mit abnehmender Blechstärke (erheblich) einfacher und damit kostengünstiger wird.Since one always tries from a cost and economic point of view, the necessary Keeping the use of materials as small as possible is also a matter of the generic type Wood connectors strive for the lowest possible material thickness for the respective Strength requirements (just about) are sufficient, especially since a deformation of sheet metal blanks by bending, bending etc. with decreasing sheet thickness (considerably) easier and thus becomes cheaper.

Aus der US 2 255 321 ist ein aus dünnem Blech bestehender Holzverbinder zum stimseitigen Anschluß eines Balkens an ein Bauteil bekannt, der einen entweder an die Stirnseite des anzuschließenden Balkens oder an dessen eine Außenseite anzulegenden und dort mit Nägeln zu befestigenden zweilagigen Befestigungsflansch aufweist, sowie einen winklig zu diesem verlaufenden, einlagig ausgebildeten weiteren Befestigungsflansch, der unter Anlage an das Bauteil mit diesem durch Nägel zu verbinden ist. Dabei steht die nicht unmittelbar mit dem einlagigen Befestigungsflansch verbundene Lage des zweilagigen Befestigungsflansches unter Bildung eines Anschlußflansches über den Scheitel zwischen den beiden Befestigungsflanschen vor und wird bei der Montage in das Bauteil eingetrieben. From US 2 255 321 a wooden connector consisting of thin sheet metal is used for the face end Connection of a bar to a component known that either one of the front of the to be connected to the beam or to be placed on its outside and there with nails has to be attached two-layer mounting flange, and an angle to this running, one-ply formed additional mounting flange, which is attached to the Part to be connected to this with nails. It is not directly related to the single-layer mounting flange connected position of the two-layer mounting flange forming a connecting flange over the apex between the two Mounting flanges in front and is driven into the component during assembly.

Aus der DE 86 26 872 U ist ein aus einem einteiligen Blechstreifen bestehender Holzverbinder zum Verbinden einer Firstbohle mit zwei Dachsparren bekannt, der ein U-förmiges Mittelteil aufweist, welches die Firstbohle an ihrem Anschlußende von unten her umgreift, wobei sich vom oberen Rand der beiden Schenkel des Mittelteils aus jeweils ein Befestigungsflansch nach unten erstreckt, der mit einem Sparren zu verbinden ist. Dabei können die beiden Schenkel des U-förmigen Mittelteils dadurch verstärkt sein, daß jeder Befestigungsflansch vom oberen Rand eines U-Schenkels aus zunächst parallel zu diesem nach unten abgekantet ist, und erst vom Bodenbereich des Mittelteils aus - dem betreffenden Sparren folgend - schräg nach unten verläuft.DE 86 26 872 U describes an existing one-piece sheet metal strip Known wooden connector for connecting a ridge plank to two rafters, which is a U-shaped Middle part, which the ridge plank at its connection end from below encompasses, one each from the upper edge of the two legs of the central part Mounting flange extends downwards, which is to be connected with a rafter. there can the two legs of the U-shaped central part be reinforced in that each Mounting flange from the upper edge of a U-leg initially parallel to this is folded down, and only from the bottom area of the middle part - the one in question Following rafters - runs diagonally downwards.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, den bekannten Holzverbinder der eingangs beschriebenen Gattung unter den vorgenannten Gesichtspunkten so zu verbessern, daß sein zweiter Befestigungsflansch trotz einer Fertigung des Holzverbinders aus einem möglichst dünnen Blech, dessen Materialstärke für die erforderliche Festigkeit des Anschlußflansches ausreicht, eine hinreichende Biegesteifigkeit aufweist.The present invention has for its object the known wood connector to improve the genus described at the outset from the aforementioned points of view, that his second mounting flange despite the manufacture of the wood connector from one The thinnest possible sheet, the material thickness for the required strength of the Connection flange is sufficient, has sufficient bending rigidity.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1.This object is achieved according to the invention by the characterizing features of claim 1.

Obwohl sich bei entsprechenden Versuchen gezeigt hat, daß die erfindungsgemäß vorgesehene mehrlagige Ausbildung von Abschnitten des Holzverbinders, die im Einbauzustand größeren Beanspruchungen (insb. auf Biegung) unterworfen sind, i.a. bereits ausreicht, um das Widerstandmoment und damit die Festigkeit ausreichend zu erhöhen, kann es vorteilhaft sein, wenn in einem mehrlagigen Bereich zumindest ein freier Rand mit dem darunter oder/und darüber liegenden Abschnitt des Holzverbinders verbunden ist, was zweckmäßigerweise durch Verschweißen erfolgen kann, und zwar in besonders einfacher Weise durch Punktschweißung. Although tests have shown that the invention envisaged multilayer training of sections of the wood connector, which in Are subject to greater stresses (especially on bending), i.a. already sufficient to increase the section modulus and thus the strength sufficiently it may be advantageous if in a multilayer area at least one free edge with the underneath and / or overlying section of the wood connector is connected what can expediently be carried out by welding, in a particularly simple manner Way by spot welding.

Eine auf das gleiche Ziel abstellende andere Ausgestaltung besteht darin, daß aneinanderliegende, parallele Abschnitte des Holzverbinders - an wenigstens einer Stelle - miteinander verbunden sind, was ebenfalls durch Verschweißung oder aber auch durch Verklebung erfolgen kann.Another embodiment that aims at the same goal is that adjacent, parallel sections of the wooden connector - at least at one point - are connected to each other, also by welding or by Can be glued.

Obwohl der Anschlußflansch ggf. in einen entsprechenden Schlitz des anzuschließenden Balkens greifen könnte, ist zweckmäßigerweise vorgesehen, daß er im montierten Zustand als Auflagerflansch fungiert, nämlich auf der Oberseite des anzuschließenden Balkens aufliegt und dort mit Nägeln od.dgl. befestigt wird. Da dieser Auflagerflansch i.w. lediglich die Funktion einer Zuglasche hat, also im montierten Zustand unter Belastung i.w. lediglich durch in seiner Längsrichtung verlaufende Zugkräfte beansprucht wird, kann er ohne weiteres (erheblich) dünner als der zweite Befestigungsflansch sein, und ist daher lediglich einlagig ausgebildet.Although the connection flange may be in a corresponding slot in the to be connected Could grab bar is conveniently provided that it in the assembled state as Support flange acts, namely rests on the top of the beam to be connected and there with nails or the like. is attached. Since this support flange i.w. only that Has the function of a pull tab, i.e. in the assembled state under load i.w. just by tensile forces extending in its longitudinal direction are easily used (considerably) thinner than the second mounting flange, and is therefore only one layer educated.

Um den Auflagerflansch bei der Montage nicht durch Hammerschläge od.dgl. erst so verformen zu müssen, daß seine dem ersten Befestigungsflansch zugekehrte Unterseite auf dem anzuschließenden Balken bündig aufliegt, kann der Auflagerflansch benachbart zum ersten Befestigungsflansch so in Richtung zum ersten Befestigungsflansch versetzt ausgebildet sein, daß seine Unterseite zur Unterseite des zweiten Befestigungsflansches i.w. fluchtet.To the support flange during assembly not by hammer blows or the like. just like that to deform that its underside facing the first mounting flange the beam to be connected rests flush, the support flange can be adjacent to offset the first mounting flange in the direction of the first mounting flange be designed so that its underside to the underside of the second mounting flange i.w. flees.

Bevorzugt sind die Durchgangsöffnungen wenigstens eines Flansches wenigstens teilweise so ausgebildet, daß sie in an sich bekannter Weise eine schräge Zwangsführung für das jeweils durch sie einzutreibende Verbindungsmittel bilden, deren Mittelachse daher im montierten Zustand nicht rechtwinklig zu dem betreffenden Flansch bzw. dessen Auflagefläche verläuft, wie dieses weiter unten unter Bezugnahme auf die Zeichnung noch weiter verdeutlicht ist. The through openings of at least one flange are preferably at least partially so trained that they in a manner known per se oblique positive control for each by connecting means to be driven, the central axis of which is therefore in the assembled Condition is not perpendicular to the flange or its contact surface, as this is further clarified below with reference to the drawing.

Um die Biegefestigkeit des Holzverbinders bzw. eines Abschnittes des Holzverbinders weiter zu erhöhen, kann wenigstens ein Flanschabschnitt durch wenigstens eine eingeformte Sicke verstärkt sein. So hat es sich als höchst vorteilhaft herausgestellt, wenn der zweite Befestigungsflansch und/oder der Auflagerflansch mit wenigstens einer dem ersten Befestigungsflansch abgekehrten, durchgehenden Sicke versehen ist.The bending strength of the wooden connector or a section of the wooden connector can increase, at least one flange section through at least one molded bead be reinforced. So it turned out to be extremely advantageous if the second Mounting flange and / or the support flange with at least one of the first Fastening flange facing away, continuous bead is provided.

Die Fig. 1 - 3 zeigen einen im ganzen mit 1 bezeichneten Holzverbinder aus dünnem Blech mit einer Wandstärke s von 2 mm zum stimseitigen Anschluß eines ersten Holzbalkens 2 an einen quer zu diesem verlaufenden zweiten Holzbalken 3. Der Holzverbinder 1 besitzt einen an die Stirnseite 2' des anzuschließenden ersten Balkens 2 anzulegenden zweilagigen ersten Befestigungsflansch 4, und einen sich von diesem weg erstreckenden, an eine Seitenfläche 3' des zweiten Balkens 3 anzulegenden dreilagigen zweiten Befestigungsflansch 6.1 - 3 show a wooden connector made of thin sheet metal, designated overall by 1 with a wall thickness s of 2 mm for the frontal connection of a first wooden beam 2 a transverse to this second wooden beam 3. The wooden connector 1 has one to the end face 2 'of the first beam 2 to be connected two-layer first Mounting flange 4, and a extending from this, on a side surface 3 ' of the second beam 3 three-layer second mounting flange 6.

Die beiden Befestigungsflansche 4, 6 sind jeweils mit Durchgangsöffnungen 7, 8 und 9 bzw. 10 versehen, durch welche längliche Verbindungsmittel wie Nägel 11 (s. Fig. 4) in die miteinander zu verbindenden Balken 2, 3 einzutreiben sind, wobei die Durchgangsöffnungen 7 des ersten Befestigungsflansches 4 als schräg zu dessen Anlagefläche 4' verlaufende Durchgangsbohrungen ausgebildet sind, die eine schräge Zwangsführung für den jeweils einzutreibenden Nagel 11 aufweisen, dessen Mittelachse 11' (s. Fig. 4) mithin im montierten Zustand nicht rechtwinklig zu dem ersten Befestigungsflansch 4 bzw. dessen Anlagefläche 4' verläuft, um auch bei dem erfindungsgemäßen Holzverbinder die vorteilhaften Wirkungen zu erzielen, die in der DE 296 10 381.0 U1 erstrebt und erzielt werden.The two mounting flanges 4, 6 are each with through openings 7, 8 and 9 and 10 provided by which elongated connecting means such as nails 11 (see. Fig. 4) in the beams 2, 3 to be connected with one another are to be driven, the through openings 7 of the first mounting flange 4 as extending obliquely to its contact surface 4 ' Through holes are formed, which are an oblique positive guide for each have to be driven in nail 11, the central axis 11 '(see FIG. 4) thus in the assembled Condition not perpendicular to the first mounting flange 4 or its contact surface 4 ' runs in order to also have the advantageous effects in the wood connector according to the invention achieve, which is striven for and achieved in DE 296 10 381.0 U1.

Wie aus Fig. 1 ersichtlich ist, ist die Dicke des zweiten Befestigungsflansches 6 durch einmaliges Umkanten des entsprechenden Blechzuschnittes an dem dem ersten Holzbalken 2 abgekehrten Rand des zweiten Befestigungsflansches 6 gegenüber der Blechdicke s verdoppelt, wobei sich eine dritte Lage zwischen die beiden durch Umkanten entstandenen Lagen erstreckt, so daß die Gesamtdicke d des zweiten Befestigungsflansches 6 mithin gleich der dreifachen Blechdicke s ist, da alle Lagen flächig aneinander liegen.As can be seen from Fig. 1, the thickness of the second mounting flange 6 is through one-time edging of the corresponding sheet metal blank on the first wooden beam 2 opposite edge of the second mounting flange 6 relative to the sheet thickness s doubled, with a third layer between the two created by edging Layers extends, so that the total thickness d of the second mounting flange 6 is the same is three times the sheet thickness s because all the layers lie flat against each other.

Wie weiterhin insb. aus den Fig. 1 und 5 der Zeichnung erkennbar ist, ist die obere Lage 6' des zweitens Befestigungsflansches 6 in Richtung zum anzuschließenden ersten Balken 2 über den ersten Befestigungsflansch 4 hinaus zu einem Auflagerflansch 12 verlängert. Um dabei zu ermöglichen, daß die als Anlagefläche dienende Unterseite 12' des Auflagerflansches 12 zu der Unterseite der unteren Lage des zweiten Befestigungsflansches 6 horizontal fluchtet, und nicht erst bei der Montage durch Hammerschläge verformt zu werden braucht, kann der Auflagerflansch 12 benachbart zum ersten Befestigungsflansch 4 so in Richtung zum ersten Befestigungsflansch 4 durch Abkantung versetzt sein, daß seine Unterseite 12' zur Unterseite des zweiten Befestigungsflansches 6 fluchtet.As can also be seen in particular from FIGS. 1 and 5 of the drawing, the upper layer 6 ' the second fastening flange 6 in the direction of the first beam 2 to be connected extended beyond the first mounting flange 4 to a support flange 12. Around to enable the underside 12 'of the bearing flange, which serves as a contact surface 12 to the underside of the lower layer of the second mounting flange 6 horizontally aligned, and does not need to be deformed by hammer blows during assembly, can the bearing flange 12 adjacent to the first mounting flange 4 in the direction be offset to the first mounting flange 4 by bending that its underside 12 'to Bottom of the second mounting flange 6 is aligned.

An dieser Stelle sei darauf verwiesen, daß die parallel zueinander verlaufenden, aneinanderliegenden Lagen des zweiten Befestigungsflansches 6 durch Punktschweißung oder Klebung fest miteinander verbunden sein können.At this point it should be pointed out that the mutually parallel, adjacent Layers of the second mounting flange 6 by spot welding or gluing can be firmly connected.

Bei dem Holzverbinder 1 gem. den Fig. 1 - 4 ist der zweite Befestigungsflansch 6 dadurch dreilagig ausgebildet, daß sich eine mit der einen Lage des zweilagigen ersten Befestigungsflansches 4 unmittelbar verbundene dritte Lage zwischen die durch Umkanten des Blechzuschnittes entstandenen beiden Lagen erstreckt, so daß der dem Auflagerflansch 12 abgekehrte Rand des zweiten Befestigungsflansches 6 abgerundet ist.With the wooden connector 1 acc. 1-4, the second mounting flange 6 is thereby three layers that one with the one layer of the two-layer first Fastening flange 4 directly connected third layer between the edges of the sheet metal blank produced two layers extends so that the bearing flange 12th opposite edge of the second mounting flange 6 is rounded.

Von dieser Ausgestaltung unterscheidet sich die Variante gem. den Fig. 5 - 8 lediglich dadurch, daß eine mit der anderen Lage des zweilagigen ersten Befestigungsflansches 4 unmittelbar verbundene drittel Lage des zweiten Befestigungsflansches 6 sich unterhalb der durch Umkanten des Befestigungsflansches entstandenen beiden Lagen erstreckt und an dem dem Auflagerflansch 12 abgekehrten Rand des zweiten Befestigungsflansches 6 stumpf endet, so daß die beiden oberen Lagen des zweiten Befestigungsflansches durch entsprechende Umkantung abgerundet sind.The variant differs from this embodiment according to. 5-8 only in that one with the other layer of the two-layer first mounting flange 4th directly connected third position of the second mounting flange 6 is below the extends by folding the mounting flange two layers and on the the edge of the second fastening flange 6 facing away from the support flange 12 ends bluntly, so that the two upper layers of the second mounting flange by appropriate Edging are rounded.
