Titel: Stahlgurknoten für geschweißte Knoten-St ab-Verbindungen bei Raumfachwerken aus Rechteckrohren Anwendungsgebiet: Die Erfindung betrifft einen Stahlgußknoten für geschweilote Knoten-Stab-Verbindungen bei Raumfachwerken mit Rechteckrohren.Title: Stahlgurknoten for welded knot-stab connections at Space framework made of rectangular tubes Field of application: The invention relates to a Cast steel knots for welded knot-rod connections in space frameworks with Rectangular tubes.
Zweck: Bei derartigen Raumfachwerken ist es erforderlich, daR die auftretenden Stabkräfte (Zug- und Druckkrafte) auf direktem Wege vom Stab (Rechteckrohr) über die Schweiftnaht zentrisch in den Knoten eingeleitet werden.Purpose: With such space frameworks it is necessary that the occurring bar forces (tensile and compressive forces) directly from the bar (rectangular tube) be introduced centrally into the knot via the tail seam.
Stand der Technik: Stahlgußknoten für geschweiP..te Enoten-Stab-Verbindungen bei Raumfachwerken aus Rechteckrohren sind nicht bekannt.State of the art: Cast steel knots for welded joint-rod connections with space frameworks made of rectangular tubes are not known.
Aufgabe: Der Erfindung liegt die Aufgabe zugrunde mit einem Stahlgu9;knoten die Raumfachwerkstabe aus Rechteckrohren übergangslos durch Schweißen zu verbinden.Task: The invention is based on the task with a steel gu9; knot to connect the space frame bars made of rectangular tubes seamlessly by welding.
Lösung: Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß der Stahlgu@-knoten spiePantgestellte Untergurtstab-, Obergurtstab- und Diagonalstabanschlustutzen hat (Bl. 1, Fig. 1; Bl. 2, Fig. 2; Bl. 3, Fig. 3), die an den Enden pyramidenstumpfförmig ausgenommen sind (Bl. 4, Fig. 4, Ziff. 2), so da die Wanddicken der Rechteckrohre mit geringer Dickendifferenz in den Knotenquerschnitt übergehen (Bl. 4, Fig. 4, Ziff. 1 + 4).Solution: This object is achieved according to the invention in that the Steel gu @ -knot spoked lower chord bar, upper chord bar and diagonal bar connection nozzles (Bl. 1, Fig. 1; Bl. 2, Fig. 2; Bl. 3, Fig. 3), which are truncated pyramidal at the ends are excluded (Bl. 4, Fig. 4, No. 2), so that the wall thicknesses of the rectangular tubes merge into the node cross-section with a slight difference in thickness (sheet 4, fig. 4, Clauses 1 + 4).
Aufgrund der Anpassung der Knotenstutzen an den Querschnitt der Rechteckrohre können Wärmespannungen beim Aufbringen der Schweißnaht (Bl. 4, Fig. 4, Ziff. 3) zwis-hen Stab und Knoten in dem massiven Knotenmaterial vermieden werden. Due to the adaptation of the nodal connection to the cross-section of the rectangular tubes thermal stresses can occur when the weld seam is applied (Bl. 4, Fig. 4, No. 3) between rod and knot in the massive knot material can be avoided.
Weitere Ausgestaltung der Erfindung: 1. Um mit solchen Stahlgu£knoten grobe Raumfachwerkteile in der Werkstatt vorfertigen zu können, sind nach einer weiteren Ausbildung der Erfindung die Obergurtknoten halbiert (Bl. 5, Fig. 5, Bl. 6, Fig. 6, Bl. 7, Fig. 7) und an zwei Obergurtstutzen mit mindestens je einer Bohrung (Bl. 5, Fig. 5, Ziff. 5) versehen, so da? je zwei halbe Knoten mit KV-Schrauben verbunden werden können; an je einem halben Knoten eines vorgefertigten Raumfachwerkteiles werden 3 Gurtstäbe und 2 Diagonalstäbe, an dem anderen zugehörigen halben Knoten eines vorgefertigten Raumfachwerkteiles werden je 1 Gurtstab und 2 Diagonalstäbe angeschweißt. Außer den Baustellenstoßen in Längsrichtung sind an der Baustelle dan in der Obergurtebene in einer Richtung nur noch die halben Drlotenstö^e zu verschweiDen sowie in der Untergurtebene in einer Richtung die Untergurtstnbe einzufügen. Die halben Knoten werden im Bereich gedrückter Gurtstäbe verwandt.Further embodiment of the invention: 1. To knot with such steel cast To be able to prefabricate rough space truss parts in the workshop are after a further embodiment of the invention, the upper chord knot halved (Bl. 5, Fig. 5, Bl. 6, Fig. 6, Bl. 7, Fig. 7) and on two upper flange nozzles with at least one hole each (Bl. 5, Fig. 5, No. 5) provided, so there? two half knots each with KV screws can be connected; at half a knot each of a prefabricated space framework part 3 chord bars and 2 diagonal bars are attached to the other associated half knot of a prefabricated space framework part are each 1 belt bar and 2 diagonal bars welded on. Except for the construction site joints in the longitudinal direction are at the construction site Then in the upper chord level only half the drlotenstocks have to be welded in one direction as well as to insert the lower chord bars in one direction in the lower chord level. the half knots are used in the area of pressed chord bars.
2. Um das Gewicht der Knoten bei groben Abmessungen zu reduzieren, ist nach einer weiteren Ausbildung der Erfindung der Knoten als Hohlkörper ausgebildet. Die verbleibenden Wanddicken um den zentralen Hohlbereich sowie die Stutzen zum Anschluß der Stäube sind im allgemeinen geringeren Beanspruchungen unterworfen als die Stab. 2. In order to reduce the weight of the knots with large dimensions, is formed according to a further embodiment of the invention, the node as a hollow body. The remaining wall thicknesses around the central hollow area as well as the nozzles for Connection of the dusts are generally less exposed to stress than the rod.
Erzielbare Vorteile: Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, 1. da3 durch diese StahlguRknoten Schweivanschlüsse ermöglicht werden zur Übertragung großer Stabkräfte; 2. daR Rastergrößen nur begrenzt sind durch die Kraftübertragungsmöglichkeit des Stabes bzw. der SchweiE.naht; 3. daS die Optimierung des Fachwerkgewichtes für den Einzelfall möglich ist, da hier auch der Parameter Fachwerkraster eingehen kann; 4. daß grobe Raumfachwerkteile in der Werkstatt oder auch in der Feldfabrik vorgefertigt werden können; 5. daß die Verwendung dieses Stahlzu'knotens eine wirtschaftliche Lösung zur Erfüllung der gestellten Aufgabe darstellt.Achievable Advantages: The advantages achieved with the invention exist in particular, 1. that welded connections are made possible by these steel cast-iron knots are used to transfer large bar forces; 2. That grid sizes are only limited due to the power transmission possibility of the rod or the welding seam; 3. the the optimization of the truss weight for the individual case is possible, as here too the parameter truss grid can be included; 4. that coarse framework parts in the Can be prefabricated in the workshop or in the field factory; 5. that the use this Stahlzu'knotens an economical solution to meet the requirements Task represents.
