Abstract

Es handelt sich um ein Profileisen zur Verwendung als Gurt oder Staender in Fachwerktraegern und aehnlichen Baustrukturen. Das Profil sollte so ausgebildet werden, dass es bei geringem Eigengewicht die Anbringung gleicher Anschlussteile fuer die Wandstaebe des Gurts bzw.

Erreicht wurde dies dadurch, dass jeder Flansch (11, 11a) des Winkelprofils (10) zwei jeweils rechtwinkelig aufeinander stehende Verlaengerungsschenkel (12, 13 bzw. 12a, 13a) besitzt, die je eine der halben Breite des Flansches entsprechende Breite besitzen. Dabei weist jeweils ein erster Schenkel (12 bzw. 12a) in die Richtung des anderen Flansches und ein zweiter Schenkel (13 bzw. 13a) in eine sich von diesem entfernende Richtung.It is a profiled iron for use as a belt or stand in trusses and similar structures. The profile should be designed in such a way that it allows the attachment of the same connecting parts for the wall bars of the belt or stand in a way that it does not experience any bending moments due to these wall bars. This was achieved in that each flange (11, 11a) of the angular profile (10) has two extension legs (12, 13 or 12a, 13a), each standing at right angles to one another, each having a width corresponding to half the width of the flange. A first leg (12 or 12a) points in the direction of the other flange and a second leg (13 or 13a) in a direction away from it.

Description

"Profileisen zur Verwendung als Gurt oder Staender in Fachwerktraegern und aehnlichen Baustrukturen""Profile iron for use as a belt or stand in trusses and similar structures"

Die Erfindung betrifft ein Profileisen zur Verwendung als Gurt oder Staender in Fachwerktraegern oder aehnlichen Baustrukturen.The invention relates to a profile iron for use as a belt or stand in trusses or similar structures.

Baustrukturen, wie beispielsweise Fachwerke wurden bisher unter Verwendung von vier Gurten oder Stapndern aus warm- oder kaltgewalzten Profileisen hergestellt, die untereinander durch Wandstaebe verbunden wurden.Building structures such as trusses have been produced using four belts or Sta p change from hot or cold rolled profile bars that are interconnected by Wandstaebe.

Insbesondere wurden hierfuer warmgewalzte 1-Profile mit breiten, normalen oder schmalen Flanschen verwendet.In particular, hot-rolled 1-sections with wide, normal or narrow flanges were used for this.

Die Breitflansch - I-Profile weisen den Nachteil eines uebermaessigen Gewichtes auf, so dass sie sich nicht fuer wirtschaftliche Leichtstrukturen eignen. Nachdem diese Profile zwei verschiedene Symmetrieachsen besitzen, ergibt sich ferner an den beiden Hauptseiten des Fachwerkes eine unterschiedliche Befestigungsart der Wandstaebe.The wide flange I-profiles have the disadvantage of excessive weight, so that they are not suitable for economical light structures. Since these profiles have two different axes of symmetry, there is also a different type of fastening of the wall bars on the two main sides of the framework.

I-Profile mit normalen oder schmalen Flanschen besitzen wohl den ersteren gegenueber ein geringeres Gewicht, doch haben sie betraechtlich unterschiedliche Traegheitshalbmesser und erfordern daher eine starke Ueberdimensionierung an der Seite geringerer Traegheit, waehrend die unterschiedliche Befestigung der Wandstaebe an den beiden Seiten noch staerker ausgepraegt ist.I-profiles with normal or narrow flanges probably have a lower weight compared to the former, but they have different diameters of inertia and therefore require a large oversize on the side of lower inertia, while the different fastening of the wall bars on the two sides is even more pronounced.

Auch fuer U-Profile gelten die gleichen Ueberlegungen wie fuer I-Profile mit normalen oder schmalen Flanschen.The same considerations apply to U-profiles as for I-profiles with normal or narrow flanges.

Winkelprofile mit gleichbreiten Flanschen sind dank der Einfachheit der Anbringung der Anschlussteile fuer die Wandstaebe vorteilhaft, da die beiden Flansche gemaess der Profilkante angeordnet sind, doch ist ihr geringster Traegheitshalbmesser sehr klein, was erhebliche Ueberdimensionierungen erforderlich macht. Nachdem ferner der Schwerpunkt dieser Winkelprofile ausserhalb der Ebenen der beiden Flanschen liegt, ergeben sich stets Nebenwirkungen, wie Biegemomente, die Ueberdimensionierungen erforderlich machen und daher beachtliche Eigengewichte zur Folge haben.Angle profiles with flanges of the same width are advantageous thanks to the simplicity of attaching the connecting parts for the wall bars, since the two flanges are arranged according to the profile edge, but their smallest inertia radius is very small, which necessitates considerable oversizing. Since the center of gravity of these angle profiles lies outside the planes of the two flanges, there are always side effects, such as bending moments, which make oversizing necessary and therefore result in considerable dead weights.

Es werden auch Rohrprofile mit kreisfoermigFm oder quadratischem Querschnitt angewandt, wobei insbesondere die letzteren eine gewisse Einfachheit der Zeichnung und der Montage mit sich bringen, da sie an zwei zueinander rechtwinkelig stehenden Seiten gleiche Symmetrieachsen besitzen. Sie haben auch grosse Traegheitshalbmesser und koennen daher mit geringem Gewicht ohne Ueberdimensionierung hergestellt werden, doch sind ihre Herstellungskosten zufolge der Notwendigkeit, die Elemente untereinander dicht zu verschweissen (im Einklang mit den Bestimmungen zur Rostverhuetung) uebermaessig gross. Es ergibt sich daher die Notwendigkeit, bei runden Rohren den Schnitt zu fassonieren und bei quadratischen und runden Rohren das Teil zur Schweissung am Umfang zu bewegen.Pipe profiles with a circular shape or a square cross-section are also used, the latter in particular having a certain simplicity of drawing and assembly, since they have the same axes of symmetry on two sides which are perpendicular to one another. They also have large inertial dimensions and can therefore be manufactured with little weight without oversizing, but their manufacturing costs are excessive due to the need to weld the elements tightly together (in accordance with the regulations for rust prevention). There is therefore a need to shape the cut for round pipes and to move the part for welding on the circumference for square and round pipes.

Aufgabe der Erfindung ist es, ein Profileisen zur Verwendung als Gurt oder Staender in Baustrukturen im allgemeinen und insbesonder in rachwerktraegern zu schaffen, welches die Nachteile der bisher verwendeten Profileisen beseitigt und eine einfache Befestigung der Wandstaebe gestattet, ohne dass dieselben Biegemomente hervorrufen.The object of the invention is to provide a profiled iron for use as a belt or stand in building structures in general and in particular in rachwerktraegern, which eliminates the disadvantages of the previously used profiled iron and allows easy attachment of the wall bars without causing the same bending moments.

Es wurde daher ein besonders geformtes und bemessenes Profileisen geschaffen, bei dem die ueber die Anschlussteile der Wandstaebe wirkenden Kraefte durch die Schwerachse des Profils verlaufen.A specially shaped and dimensioned profile iron was therefore created, in which the forces acting on the connecting parts of the wall bars run through the center of gravity of the profile.

Die Loesung der gestellten Aufgabe wurde mit einem Winkeleisen mit gleichbreiten Flanschen gefunden, das dadurch gekennzei chnet ist, dass jeder Flansch an seinem freien Ende durch einen ersten Schenkel, dessen Breite gleich der halben Flanschbreite ist und der im rechten Winkel zu diesem in der gleichen Richtung wie der andere Flansch angeordnet ist, sowie durch einen zweiten Schenkel verlaengert ist, der ebenfalls eine der halben Flanschbreite entsprechende Breite besitzt und der im rechten Winkel zum ersten Schenkel in einer sich vom anderen Flansch des Winkeleisens entfernenden Richtung angeordnet ist.The solution to the problem was found with an angle iron with flanges of equal width, which is characterized in that each flange at its free end by a first leg, the width of which is equal to half the flange width and at right angles to this in the same direction how the other flange is arranged, and is extended by a second leg, which also has a width corresponding to half the flange width and which is arranged at right angles to the first leg in a direction away from the other flange of the angle iron.

Mit einem Profileisen dieser Art erreicht man, dass sich die Wirkungslinien der ueber die Anschlussteile der Wandstaebe auf den Gurt bzw. den Staender einwirkenden Kraefte auf der Schwerachse des Profileisens schneiden, so dass die auf Biegemomente zurueckzufuehrenden Nebenwirkungen praktisch null sind. Nachdem das Profileisen ferner ebene, aufeinander im rechten Winkel stehende Endschenkel besitzt, lassen sich die Anschlussteile fuer die Wandstaebe einfach und voellig symmetrisch auf beiden Seiten befestigen. Das erfindungsgemaesse Profileisen hat auch einen grossen Traegheitshalbmesser, so dass uebermaessige Ueberdimensionierungen vermieden werden koennen und das Profileisen folglich ein beschraenktes Eigengewicht besitzt, welches es gestattet, unter sonst gleichen Bedingungen groessere Lichtweitdn mit geringerem Stich zu ueberbruecken.With a profile iron of this type, the effect lines of the forces acting via the connecting parts of the wall bars on the belt or the stand intersect on the axis of gravity of the profile iron, so that the side effects attributable to bending moments are practically zero. After the profile iron also has flat end legs that are at right angles to one another, the connecting parts for fasten the wall bars easily and completely symmetrically on both sides. The profile iron according to the invention also has a large inertia radius, so that excessive oversizing can be avoided and the profile iron consequently has a limited dead weight, which makes it possible to bridge larger light widths with a smaller stitch under otherwise identical conditions.

Ein weiterer Vorteil des erfindungsgemaessen Profileisens ist der, dass zur Ausfuehrung der Konstruktionszeichnungen fuer den Fachwerktraeger geringere Zeiten erforderlich sind, da man lediglich die Lage der Anschlussteile fuer die Wandstaebe festlegen braucht, wobei die Anschlussteile in Form von Platten, Winkeln oder dergleichen ausgebildet sein koennen, die an den betreffenden Stellen angeschraubt oder auch angeschweisst werden koennen. Es ergibt sich somit eine besonders einfache Konstruktion und Montage unter Heranziehung billiger Standardteile.Another advantage of the profiled iron according to the invention is that shorter times are required to carry out the construction drawings for the truss, since only the position of the connecting parts for the wall bars need be determined, the connecting parts being able to be in the form of plates, angles or the like, which can be screwed or welded to the relevant points. This results in a particularly simple construction and assembly using cheap standard parts.

Das erfindungsgemaesse Profileisen zur Verwendung als Gurt oder Staender ist in der einzigen Zeichnungsfigur im Querschnitt dargestellt.The profile iron according to the invention for use as a belt or stand is shown in cross section in the single drawing figure.

Das allgemein mit 10 bezeichnete Profil besteht aus einem Winkeleisen mit zwei gleich breiten Flanschen 11, 11a, von deren freien Enden aus sich abgebogene Verlaengerungsschenkel 12, 13 bzw. 12a, 13a erstrecken. Insbesondere ist ein erster Schenkel 12 bzw. 12a vorhanden, dessen Breite gleich der halben Breite eines Flansches 11 bzw. 11a des Winkeleisens ist und der im-rechten Winkel zu dem zugehoerigen Flansch 11 bzw. 11a in der gleichen Richtung wie der andere Flansch des Winkeleisens steht. Ferner ist ein zweiter Schenkel 13 bzw. 13a vorhanden, dessen Breite ebenfalls gleich der halben Breite eines Flansches 11 bzw. 11a des Winkeleisens ist und der bezueglich des ersten Schenkels 12 bzw. 12a im rechten Winkel steht und sich in einer Richtung derart erstreckt, dass er sich vom anderen Flansch 11a bzw. 11 des Winkeleisens entfernt.The profile, generally designated 10, consists of an angle iron with two flanges 11, 11a of the same width, from the free ends of which bent extension legs 12, 13 and 12a, 13a extend. In particular, there is a first leg 12 or 12a, the width of which is equal to half the width of a flange 11 or 11a of the angle iron and which is at right angles to the associated flange 11 or 11a in the same direction as the other flange of the angle iron sens stands. Furthermore, there is a second leg 13 or 13a, the width of which is also equal to half the width of a flange 11 or 11a of the angle iron and which is at right angles with respect to the first leg 12 or 12a and extends in one direction such that it moves away from the other flange 11a or 11 of the angle iron.

Es erscheint klar, dass es sich um ein voellig symmetrisches Profil handelt, dessen mit G bezeichnete Schwerachse durch die Schnittlinie der beiden, durch die Mitten der Verlaengerungsschenkel 13 und 13a verlaufenden Ebenen gebildet ist.It appears clear that this is a completely symmetrical profile, the center of gravity designated by G is formed by the intersection of the two planes running through the centers of the extension legs 13 and 13a.

Wenn an diesen Schenkeln 13, 13a des Profils 10 Anschlussteile in Form von Platten, Winkelplatten oder aehnlichen Elementen angeschraubt (wie auf der Zeichnung angedeutet) oder auch angeschweisst werden, an denen wieder die Wandstaebe des Fachwerktraegers befestigt werden, dann koennen an beiden Seiten des Gurts oder Staenders nicht nur dieselben Anschlussteile verwendet werden, sondern es ist auch ersichtlich, dass sich die Wirkungslinien der ueber die Anschlussteile auf das Profil einwirkenden Kraefte auf der Schwerachse des Profils schneiden, so dass keinerlei Biegemomente entstehen, die zu schaedlichen Nebenwirkungen fuehren koennten.If 10 connecting parts in the form of plates, angle plates or similar elements are screwed or welded onto these legs 13, 13a of the profile (as indicated in the drawing), to which the wall bars of the truss girder are fastened again, then the belt can be attached to both sides not only the same connecting parts are used, but it can also be seen that the lines of action of the forces acting on the profile via the connecting parts intersect on the center of gravity of the profile, so that no bending moments arise that could lead to harmful side effects.

Bei der dargestellten Ausfudrungsform bestehen die Anschlussteile fuer die Wandstaebe 14, 15 aus einer mittels einer Rippe 17 verstaerkten Winkelplatte 16, die an zwei Seiten an den Schenkeln 13, 13a des Profils 10 befestigt ist. Auf diese Weise wird auch jegliche Gefahr eines Verbiegens der Schenkel 12, 12a in bezug auf die betreffenden Flansche 11, 11a des Profils beseitigt.In the embodiment shown, the connecting parts for the wall bars 14, 15 consist of an angled plate 16 reinforced by means of a rib 17, which is attached to the legs 13, 13a of the profile 10 on two sides. In this way, any risk of bending the legs 12, 12a in relation to the relevant flanges 11, 11a of the profile is eliminated.

Es ist auch ersichtlich, dass das erfindungsgemaesse Profil einen grossen Traegheitshalbmesser besitzt, so dass es mit geringem Eigengewicht ausgefuehrt und fuer Leichtstrukturen verwendet werden kann, die auch grosse Lichtweiten mit kleinem Stich ueberbruecken koennen.It can also be seen that the profile according to the invention has a large inertia radius, so that it can be carried out with a low dead weight and can be used for light structures which can also bridge large light widths with a small stitch.

Das Profil nach der Erfindung kann im Kaltbiegeverfahren hergestellt werden, obwohl es auch ohneweiters moeglich ist, es im Warmwalzverfahren herzustellen.The profile according to the invention can be produced in the cold bending process, although it is also possible to produce it in the hot rolling process.
