Die bekannte, beschriebene Technik weist jeden¬ falls einige Nachteile auf. Zur Aufnahme der verschiedenen Beanspruchungen, insbesondere jener, die senkrecht (Zug) und jener die parallel (Scherung) zum Knick liegen, dienen verschiedene Arten von Ve r b i n du n g s t e i 1 e , vor allem bei Haus- konstruktionen aus massiven Holz mit der Typologie „crosslam", auch als XLAM oder CLT bezeichnet . The known, described technique has any ¬ if some disadvantages. To accommodate the various stresses, in particular those that are perpendicular (tensile) and parallel (shear) to the kink, various types of inhibition are used, especially in households. Structures made of solid wood with the typology "crosslam", also referred to as XLAM or CLT.

Um die Steifheit des Winkel¬ stücks aufgrund der zum Knick parallelen Beanspruchung zu erhöhen, sieht die bekannter Technik immer die Verwendung von verschiedenen Verstärkung s t yp e n vor, wobei auch die Stärke des Winkelstücks selbst optimiert wird. The connector referred to above, in the stress of holdown when used in a wood-wood joint (for example, wall-ceiling), requires that the walls of solid wood of the upper floor have the same thickness as those of the lower floor. To increase the stiffness of the angle ¬ tee due to the parallel to the buckling stress, the known technology always involves the use of various reinforcement st before yp s, with the strength of the elbow itself is optimized.
Die Verstärkungen sind notwendig um die Festig¬ keit sicherzustellen, bewirken jedoch erhebliche Kosten in der Herstellung und können überdies einen größeren Platzbedarf des Verbindungsstücks betragen . The reinforcements are necessary to ensure the Festig ¬ speed, however, cause considerable costs in the production and can also be a larger footprint of the connector.
Aufgabe der vorliegenden Erfindung ist die Behebung der Nachteile der bekannten Technik. Object of the present invention is to overcome the disadvantages of the prior art.
Insbesondere stellt sich die vorliegende Erfin¬ dung das Ziel, ein Verbindungsstück für Holzkonstruktionen der oben beschriebenen Art zu schaffen, das ermöglicht, eine einzige Vorrichtung für die verschiedenen Beanspruchungen (Zug und Scherung in der Ebene) zu benutzen. Eine weitere Aufgabe der vorliegenden Erfindung liegt darin, die Festigkeit und die Steifigkeit des Verbin¬ dungssystems für sehr hohe Beanspruchungen merklich zu erhöhen, wie zum Beispiel jene die von Erdbeben oder Windstößen herrühren. In particular, there is the object, the present OF INVENTION ¬ dung to provide a connector for wooden structures of the type described above, which allows to use a single device for the various stresses (shear in the train and plane). Another object of the present invention is to to increase the strength and rigidity of the Verbin ¬ training system for very high stresses noticeably, such as those arising, for example, earthquakes or wind gusts.
Um diese Aufgabe zu lösen, schlägt die Erfindun ein neues Verbindungsstück für H o 1 z k o n s t r u k t i o nen in der Form eines Me t a 11 w i n k e 1 s t ü c k s mit be sonderer Gestaltung der Bohrungen für die Befes tigungsteile mit zylinderförmigem Schaft bzw Nägeln und Vo 11 ge w i n de s ch r aub e n in Übereinstim mung mit Anspruch 1 vor. In order to solve this problem, the invention proposes a new connector for lifting constructions in the form of a straight line with special design of the bores for the fastening parts with cylindrical shank or nails and flange in accordance with claim 1.
Diese Aufgabe wird durch ein Ve r b i n du n g s s y s t em mit einem Verbindungsstück für Holzkonstruktionen gelöst, das aus einer ersten Metallplatte, bevorzugter Weise aus Stahl besteht. Die Stärke der Platte ändert sich bevorzugter Weise zwischen 3 mm und 6 mm, besonders vorteilhaft bei 4mm. Die Platte ist im wesentlichen um 90° gebogen um ein Winkelstück zu bilden. Auf der vertikalen Seite der Platte des Verbindungsstückes ist eine Reihe von Bohrungen mit Durchmesser zwischen 4 mm und 6 mm, bevorzugt von 5 mm vorgesehen, während auf der horizontalen Seite eine erste Reihe von Bohrungen mit Durchmesser d zwischen 4 mm und 6 mm, bevorzugt von 5 mm vorge¬ sehen ist. Auf der horizontalen Seite des Verbindung s t e i 1 s , in der Nähe des Knicks von 90° mit Abstand i zwischen Knick und B o h r u n g s mi t t e ist eine zweite Reihe von Bohrungen mit Durch¬ messer n zwischen 11 mm und 13 mm, bevorzugt 12 mm vorgesehen. Für die ersten Bohrungen mit kleinerem Durchmesser sind glatte oder gerillte Nägel oder Schrauben oder ähnlichem vorgesehen, während für die zweiten Bohrungen mit größerem Durchmesser Vo 11 ge w i n de s ch r a ub e n vorgesehen sind, die einen Winkel zwischen 60° und 85°, bevorzugt 75°gegenüber der horizontalen Ebene bilden . This object is achieved by a binding system with a connector for wooden constructions, which consists of a first metal plate, preferably of steel. The thickness of the plate preferably changes between 3 mm and 6 mm, particularly advantageously 4 mm. The plate is bent substantially 90 ° to form an elbow. On the vertical side of the plate of the connector, a series of holes with a diameter between 4 mm and 6 mm, preferably 5 mm provided, while on the horizontal side a first row of holes with a diameter d between 4 mm and 6 mm, preferably from 5 mm pre ¬ seen. S, a distance is provided on the horizontal side of the connecting stei 1 in the vicinity of the bend of 90 ° i between crease and B ohrungs mi tte is a second series of holes with ¬ knife n is between 11 mm and 13 mm, preferably 12 mm , For the first holes with smaller diameters are provided by smooth or grooved nails or screws or the like, while for the second, larger diameter bores, there are provided worm wheels which angle between 60 ° and 85 °, preferably 75 ° with respect to the horizontal Form level.
Die Positionierung der Vo 11 g e w i n de s ch r aub e n beträgt eine überraschende Wirkung und eine Ver¬ steifung der gesamten Verbindung, wobei eine größere Festigkeit sichergestellt wird. The positioning of the Vo 11 gewin de s ch r AUB s is a surprising effect and a ¬ Ver stiffening of the entire compound, greater strength is ensured.

Gegenüber dem Stand der Technik ist das Verbindungsstück sowohl für senkrechte Beanspruchungen (Zug) als auch für jene parallele (Scherung) zum Knick verwendbar, wobei es insoweit sich insbe¬ sondere gut für eine fortgeschrittene Berechnung von Strukturen verwenden lässt, die diese mehrfachen Beanspruchungen in Betracht zieht. Das Verbindungsstück in der Form eines Metallwinkelstücks erfordert keine weitere Verstärkung zwi¬ schen den beiden Flanschen, da in der Gesamtheit der Verbindung von Holzteilen die Vollgewindeschrauben die Verformung verhindern, die auf die Beanspruchung parallel zum Kn i c k z u r ü c k z u f üh r e n ist. Das Verbindungsstück bietet die Möglichkeit an, eine erhebliche Anzahl von Nägeln einzubringen, um den Erfordernissen von Festigkeit und Steifheit zu genügen, die durch die sehr hohen Beanspruchungen durch Erdbeben oder Wind entstehen. Das Verbindungsstück besitzt eine begrenzte H ö he n au s de hn un g , wobei es den Vorteil hat, nicht aus dem Untergrundpack vorzustehen. Das vorgeschlagene Verbindungsstück ist für die Hauskonstruktionen aus massiven Holz mit der Typologie „crosslam" (XLAM, CLT) optimiert und bietet eine Vereinfachung der Montage der H o 1 z k o n s t r u k t i o n an . Compared to the prior art said connecting piece is both vertical loads (train) as well as those parallel (shear) to the crease usable, wherein it ¬ makes good use for an advanced calculation of structures that regard, in particular sondere that these multiple stresses into consideration draws. The connecting piece in the form of a metal angle piece does not require further reinforcement Zvi ¬ rule the two flanges, as in the entirety of the bonding wood parts, the full-thread screws prevent the deformation, which is parallel to Kn ickzur ü ckzuf Uh ren to the stress. The connector offers the possibility to introduce a significant number of nails to the requirements of strength and Stiffness caused by the very high stresses caused by earthquakes or wind. The connector has a limited height, and has the advantage of not protruding from the base pack. The proposed connector is optimized for solid timber house constructions with the crosslam type (XLAM, CLT) and simplifies the assembly of the hoist construction.

Vo r t e i 1 h a f t e rwe i s e ist das durch eine Verbindung ausgeführte Ve rb i n du n g s y s t em durch ein erfindungsgemäßes Verbindungsstück gebildet, das ein erstes Holzbauteil 6 mit einem zweiten Holzbau¬ teil verbindet. Die beiden Holzbauteile bilden einen im wesentlichen rechten Winkel. Das Verbindungsstück wird durch eine erste Reihe von Vo 11 ge w i n de s ch r aub e n befestigt, die in den Bohrungen 7 mit einem Winkel a zwischen 60°-85° v o r t e i 1 h a f t e rwe i s e mit etwa 75° eingebracht sind, der durch die Schraube und die Platte ge¬ bildet wird, in der die Bohrungen angeordnet sind. Diese Bohrungen sind im wesentlichen am Knick anliegend mit einem Abstand 25 mm, bevor¬ zugter Weise mit 5 mm angeordnet. Die Verbindung wird mit einer zweiten Reihe von Nägeln und/oder Schrauben in den Bohrungen 8 festgelegt. Diese zweiten S ch r aub e n / ä ge 1 weisen einen Durchmesser auf, der gegenüber der ersten Reihe von Vollgewindeschrauben kleiner ist und im wesentlichen senkrecht in den Bohrungen gegenüber der ersten Platte und in den beiden H o 1 z k o n s t r u k t i o n s t e i 1 e n eingebracht sind. Vo r t e i 1 h a f t e r we i s e bedürfen die Vo 11 ge w i nde s c h r aub e n keine zwischen Platte und ihrem Kopf zwischengelegte Unterleg¬ scheibe/Ring . In the first embodiment, the connection executed by a connection is in the form of a connecting piece according to the invention, which connects a first wooden component 6 to a second wooden component . The two wooden components form a substantially right angle. The connecting piece is fastened by a first series of pivoting sleeves, which are inserted in the bores 7 at an angle a between 60 ° -85 ° C, at about 75 °, at about 75 ° Screw and the plate ge ¬ forms, in which the holes are arranged. These bores are substantially adjacent to the bend with a distance of 25 mm, before ¬ zugter way arranged with 5 mm. The connection is made with a second series of nails and / or screws in the holes 8. These second collars have a diameter smaller than that of the first series of full-threaded screws and inserted substantially perpendicularly in the bores opposite the first plate and in the two structural members. In the first place, the front-end hinges do not require a plate between them and her head down between flat washer ¬ disc / ring.
Es ist schließlich klar, dass am bisher beschriebenen System und Verbinder Zusätze, Abänderungen oder für den Fachmann nahe liegende Varianten vorgenommen werden können, ohne deshalb den durch die beigefügten Patentansprüche gelie¬ ferten Schutzbereich zu verlassen. z u g s ziffernlegende Finally, it is clear that the system described so far and connectors additions, modifications or obvious to those skilled variants can be made without thereby departing from the GELIE ¬ ferten by the appended claims scope. train legend
