Definitions
- the present invention relates to a structural element for constructing a projectile, with a support made of wood with a top, a bottom, two flanks and two end faces, the wood fibers are oriented at least partially in the carrier longitudinal direction.
- the invention further relates to a skeleton construction for constructing a projectile with the aid of such a component.
- Beams made of wood for example glulam (BSH) are used in professional timber engineering because of their low weight and their high heat and fire resistance for large spans, e.g. used by hall roofs or as an intermediate carrier in multi-storey buildings.
- BSH glulam
- the high pressure loads of the hall roofs or floors can cause settlement processes in the wood, which can lead to subsidence cracks, gaps and leaks in the building.
- the invention has for its object to provide a structural element for the construction of projectiles, which overcomes the disadvantages of the prior art.
- This object is achieved according to the invention with a component of the aforementioned type, in which in at least one end of a wooden bar with a graded or gezinkten to the carrier center profile is recessed positively, which extends from the top to the bottom, whose stages or Tines run from the top to the bottom, and whose wood fibers are oriented substantially in the direction from top to bottom.
- a pressure load reinforcement is created in the end region of the carrier, which has high strength due to the intimate form fit of the stepped or gezinkenten reinforcing rod.
- the carrier may be processed like any other conventional carrier in construction, with the reinforcing rod providing a stable anchoring point for connection of fittings for connection to subsequent or overlying vertical components. Due to the final reinforcement according to the invention and carriers of fast growing woods, which have a lower bulk density and thus lower strength, can be used without affecting the compressive strength and thus settlement stability of the building. Also, the grained wood surface of the carrier is largely sealed by the embedded reinforcing bar, so that the risk of moisture penetration into the wood fibers or the glue of a BSH carrier and thus a tearing of the carrier is eliminated or at least greatly reduced.
- the bar has a finger joint profile with at least two finger joints. This results in a particularly intimate fit of the finger joints of the reinforcing rod with the carrier and thus particularly high strength.
- said reinforcing rod is recessed at a distance from the flanks and / or flush with the end face, which facilitates the processing of the beam in the manner of conventional wooden beams.
- the carrier can basically be made of solid wood.
- the carrier is made of glulam whose layers are parallel or normal to the top and bottom sides and in the longitudinal direction of the carrier.
- flank angles of the finger joints of the finger joint profile are preferably self-locking in order to ensure a good absorption of force. It is also advantageous if the tips of the finger joints lie in one plane, which facilitates the milling of the finger joints in the wearer's end faces.
- the side of the rod exposed on the front side has a recess for at least partially receiving a part of a coupling element. With the help of this recess, a pre-positioning of the coupling element can be achieved during its assembly. If the rod is made of harder wood than the carrier, thereby an improved anchoring of the coupling element is achieved at the end of the carrier.
- the component can be further prefabricated for use on the construction site, by equal to the one part of a on the exposed side of the rod on the front side two-piece coupling element is screwed. The component then needs to be connected to the site only with the second, attached to a vertical component part of the coupling element.
- the invention also provides various skeleton structures for constructing projectiles, each of which comprises at least one component of the type presented here and a vertical component.
- the vertical member may be supported on the rod of the component, or conversely the member's rod may be supported on the vertical member, or the member's rod may lie between two superimposed vertical members to receive and transmit compressive loads.
- a vertical component may be provided at its upper end with a shoulder corresponding to the height of the component, on which shoulder the rod of the component is supported, resulting in an improved positive connection between the vertical component and the component.
- a coupling element one part of which is screwed to the component, in particular the exposed side of the reinforcing rod, and the other part of the vertical component.
- a component 1 which has an elongate support 2 made of wood with upper and lower sides 3, 4, flanks (lateral sides) 5, 6 and end faces 7, 8.
- an elongate support 2 made of wood with upper and lower sides 3, 4, flanks (lateral sides) 5, 6 and end faces 7, 8.

- the rods 9, 10 thereby reinforce in the installed position of the device 1, the carrier 2 in its end portions against compressive loads in the vertical direction V.
- Die Rods 9, 10 can - even if this is not mandatory - be made of a harder wood than the carrier. 2

Description
Die vorliegende Erfindung betrifft ein Bauelement zum Aufbau eines Geschoßes, mit einem Träger aus Holz mit einer Oberseite, einer Unterseite, zwei Flanken und zwei Stirnseiten, dessen Holzfasern zumindest teilweise in Trägerlängsrichtung orientiert sind. Die Erfindung betrifft ferner eine Skelettkonstruktion zum Aufbau eines Geschoßes mit Hilfe eines solchen Bauelements.The present invention relates to a structural element for constructing a projectile, with a support made of wood with a top, a bottom, two flanks and two end faces, the wood fibers are oriented at least partially in the carrier longitudinal direction. The invention further relates to a skeleton construction for constructing a projectile with the aid of such a component.
Träger aus Holz, beispielsweise Brettschichtholz (BSH), werden im professionellen Ingenieurholzbau aufgrund ihres geringen Gewichts und ihrer hohen Hitze- und Feuerresistenz für große Spannweiten z.B. von Hallendächern oder als Zwischenträger in mehrgeschoßigen Gebäuden eingesetzt. Die hohen Drucklasten der Hallendächer bzw. Geschoße können dabei Setzungsvorgänge im Holz verursachen, welche zu Setzungsrissen, Spalten und Undichtigkeiten des Gebäudes führen können.Beams made of wood, for example glulam (BSH), are used in professional timber engineering because of their low weight and their high heat and fire resistance for large spans, e.g. used by hall roofs or as an intermediate carrier in multi-storey buildings. The high pressure loads of the hall roofs or floors can cause settlement processes in the wood, which can lead to subsidence cracks, gaps and leaks in the building.
Die Erfindung setzt sich zum Ziel, ein Bauelement für den Aufbau von Geschoßen zu schaffen, welches die genannten Nachteile des Standes der Technik überwindet.The invention has for its object to provide a structural element for the construction of projectiles, which overcomes the disadvantages of the prior art.
Dieses Ziel wird gemäß der Erfindung mit einem Bauelement der einleitend genannten Art erreicht, bei welchem in zumindest eine Stirnseite zumindest ein Stab aus Holz mit einem zur Trägermitte hin abgestuften oder gezinkten Profil formschlüssig eingelassen ist, der von der Oberseite zur Unterseite reicht, dessen Stufen bzw. Zinken von der Oberseite zur Unterseite verlaufen, und dessen Holzfasern im Wesentlichen in Richtung von der Oberseite zur Unterseite orientiert sind.This object is achieved according to the invention with a component of the aforementioned type, in which in at least one end of a wooden bar with a graded or gezinkten to the carrier center profile is recessed positively, which extends from the top to the bottom, whose stages or Tines run from the top to the bottom, and whose wood fibers are oriented substantially in the direction from top to bottom.
Dadurch wird eine Drucklastverstärkung im Endbereich des Trägers geschaffen, welche durch den innigen Formschluss des abgestuften oder gezinkten Verstärkungsstabes hohe Festigkeit hat. Der Träger kann wie jeder andere herkömmliche Träger am Bau verarbeitet werden, wobei der Verstärkungsstab einen stabilen Verankerungspunkt für den Anschluss von Beschlägen zur Verbindung mit anschließenden oder darauf aufsetzenden Vertikalbauteilen bietet. Aufgrund der erfindungsgemäßen Endverstärkung können auch Träger aus schnellwachsenden Hölzern, die eine geringere Rohdichte und damit geringere Festigkeit haben, verwendet werden, ohne die Druckfestigkeit und damit Setzungsstabilität des Bauwerks zu beeinträchtigen. Auch wird durch den eingelassenen Verstärkungsstab die Hirnholzfläche des Trägers weitgehend abgedichtet, sodass die Gefahr eines Eindringens von Feuchtigkeit in die Holzfasern oder den Leim eines BSH-Trägers und damit eines Aufreißens des Trägers beseitigt oder zumindest stark reduziert wird.As a result, a pressure load reinforcement is created in the end region of the carrier, which has high strength due to the intimate form fit of the stepped or gezinkenten reinforcing rod. The carrier may be processed like any other conventional carrier in construction, with the reinforcing rod providing a stable anchoring point for connection of fittings for connection to subsequent or overlying vertical components. Due to the final reinforcement according to the invention and carriers of fast growing woods, which have a lower bulk density and thus lower strength, can be used without affecting the compressive strength and thus settlement stability of the building. Also, the grained wood surface of the carrier is largely sealed by the embedded reinforcing bar, so that the risk of moisture penetration into the wood fibers or the glue of a BSH carrier and thus a tearing of the carrier is eliminated or at least greatly reduced.
Besonders günstig ist es, wenn der Stab ein Keilzinkenprofil mit zumindest zwei Keilzinken hat. Dies ergibt einen besonders innigen Formschluss der Keilzinken des Verstärkungsstabes mit dem Träger und dadurch besonders hohe Festigkeit.It is particularly favorable if the bar has a finger joint profile with at least two finger joints. This results in a particularly intimate fit of the finger joints of the reinforcing rod with the carrier and thus particularly high strength.
Bevorzugt ist der genannte Verstärkungsstab mit Abstand zu den Flanken und/oder bündig in die Stirnseite eingelassen, was die Verarbeitung des Trägers in der Art von herkömmlichen Holzträgern erleichtert.Preferably, said reinforcing rod is recessed at a distance from the flanks and / or flush with the end face, which facilitates the processing of the beam in the manner of conventional wooden beams.
Durch die genannte Orientierung der Holzfasern des Verstärkungsstabes in Vertikalrichtung und normal zu den Holzfasern des Trägers wird bereits eine wesentliche Verstärkung des Trägerendbereichs erreicht. Die Verstärkungswirkung kann noch weiter erhöht werden, wenn der Stab aus einem härteren Holz gefertigt ist als der Träger.By said orientation of the wood fibers of the reinforcing rod in the vertical direction and normal to the wood fibers of the carrier, a substantial reinforcement of the Trägerendbereichs is already achieved. The reinforcing effect can be further increased if the rod is made of a harder wood than the carrier.
Der Träger kann grundsätzlich aus Massivholz gefertigt sein. Bevorzugt ist der Träger jedoch aus Brettschichtholz gefertigt, dessen Schichten parallel oder normal zu den Ober- und Unterseiten und in Längsrichtung des Trägers verlaufen.The carrier can basically be made of solid wood. Preferably, however, the carrier is made of glulam whose layers are parallel or normal to the top and bottom sides and in the longitudinal direction of the carrier.
Bevorzugt werden - wie auf dem Gebiet von Keilzinkenverbindungen an sich bekannt - die Flankenwinkel der Keilzinken des Keilzinkenprofils selbsthemmend ausgeführt, um eine gute Kraftaufnahme zu gewährleisten. Auch ist es günstig, wenn die Spitzen der Keilzinken in einer Ebene liegen, was das Einfräsen der Keilzinken in die Trägerstirnseiten erleichtert.As is well known in the field of finger jointing, the flank angles of the finger joints of the finger joint profile are preferably self-locking in order to ensure a good absorption of force. It is also advantageous if the tips of the finger joints lie in one plane, which facilitates the milling of the finger joints in the wearer's end faces.
Besonders günstig ist es, wenn die auf der Stirnseite freiliegende Seite des Stabes eine Ausnehmung zur zumindest teilweisen Aufnahme eines Teiles eines Kupplungselements hat. Mit Hilfe diese Ausnehmung kann eine Vorpositionierung des Kupplungselements bei seiner Montage erreicht werden. Wenn der Stab aus härterem Holz gefertigt ist als der Träger, wird dadurch auch eine verbesserte Verankerung des Kupplungselements am Trägerende erreicht.It is particularly favorable if the side of the rod exposed on the front side has a recess for at least partially receiving a part of a coupling element. With the help of this recess, a pre-positioning of the coupling element can be achieved during its assembly. If the rod is made of harder wood than the carrier, thereby an improved anchoring of the coupling element is achieved at the end of the carrier.
Das Bauelement kann für die Verwendung auf der Baustelle weiter vorkonfektioniert werden, indem an der auf der Stirnseite freiliegenden Seite des Stabes gleich der eine Teil eines zweiteiligen Kupplungselements angeschraubt ist. Das Bauelement braucht dann auf der Baustelle nur mehr mit dem zweiten, an einem Vertikalbauteil befestigten Teil des Kupplungselements verbunden werden.The component can be further prefabricated for use on the construction site, by equal to the one part of a on the exposed side of the rod on the front side two-piece coupling element is screwed. The component then needs to be connected to the site only with the second, attached to a vertical component part of the coupling element.
In einem weiteren Aspekt schafft die Erfindung auch verschiedene Skelettkonstruktionen zum Aufbau von Geschoßen, welche jeweils zumindest ein Bauelement der hier vorgestellten Art und einen Vertikalbauteil umfassen. Der Vertikalbauteil kann auf dem Stab des Bauelements abgestützt sein, oder umgekehrt kann der Stab des Bauelements auf dem Vertikalbauteil abgestützt sein, oder der Stab des Bauelements kann zwischen zwei übereinanderliegenden Vertikalbauteilen liegen, um Drucklasten aufzunehmen und zu übertragen. Auch kann ein Vertikalbauteil an seinem oberen Ende mit einem Absatz entsprechend der Höhe des Bauelements versehen sein, auf welchem Absatz der Stab des Bauelements abgestützt ist, was einen verbesserten Formschluss zwischen Vertikalbauteil und Bauelement ergibt. In jeder dieser Varianten kann zwischen dem Bauelement und dem Vertikalbauteil optional ein Kupplungselement vorgesehen sein, dessen einer Teil am Bauelement, insbesondere der freiliegenden Seite des Verstärkungsstabes, und dessen anderer Teil am Vertikalbauteil angeschraubt ist.In a further aspect, the invention also provides various skeleton structures for constructing projectiles, each of which comprises at least one component of the type presented here and a vertical component. The vertical member may be supported on the rod of the component, or conversely the member's rod may be supported on the vertical member, or the member's rod may lie between two superimposed vertical members to receive and transmit compressive loads. Also, a vertical component may be provided at its upper end with a shoulder corresponding to the height of the component, on which shoulder the rod of the component is supported, resulting in an improved positive connection between the vertical component and the component. In each of these variants may optionally be provided between the component and the vertical component, a coupling element, one part of which is screwed to the component, in particular the exposed side of the reinforcing rod, and the other part of the vertical component.
