Abstract

1. Method for producing a lattice girder with at least one zig-zag strut arranged between two beams and connected thereto and which is formed from a continuous metal band, at least one beam having a U-shaped cross-section and the metal band firstly being fixed to the back of one chord as a strut and is then connected to another chord, characterized in that prior to fixing the upper chord to the strut, a sheet metal covering, ceiling or roof layer is placed thereon and whose profile shape corresponds to that of the strut, the latter optionally comprising a lamellar portion separated from the covering layer.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines Fachwerkträgers mit mindestens einer zwischen zwei Holmen angeordneten und mit diesen verbundenen zickzackförmig verlaufenden Verstrebung, die aus einem durchlaufenden Metallband gebildet ist, wobei mindestens ein Holm einen u-förmigen Querschnitt aufweist und das Metallband erst auf der Rückseite des einen Gurts als Verstrebung befestigt und dann mit dem anderen Gurt verbunden wird und einen nach diesem Verfahren hergestellten Fachwerkträger.The invention relates to a method for producing a truss with at least one strut arranged between two spars and connected to them, which is formed from a continuous metal band, at least one spar has a U-shaped cross section and the metal band only on the back of the a belt is attached as a strut and then connected to the other belt and a truss made by this method.

Ein gattungsgemäßer Fachwerkträger ist bereits durch die AT-B-175 370 bekannt geworden. Bei diesem Fachwerkträger ist für die Verstrebung eine Längsversteifung vorgesehen, um die Knicklänge zu kürzen. Das Einbringen der Längsversteifung erhöht die Herstellungskosten dieses Fachwerkträgers. Darüberhinaus besteht bei diesem Fachwerkträger der Nachteil, daß Decken oder Deckenträger nur auf den eigentlichen Fachwerkträgern gelagert werden können. Hierdurch wird die Bauhöhe zu erstellender Gebäude um die aus statischen Gründen erforderliche Höhe der Fachwerkträger vergrößert. Nach der AT-B-279 127 ist ein weiterer Fachwerkträger mit einer zwischen zwei Holmen befindlichen zickzackförmig verlaufenden Verstrebung bekannt. Bei diesem Fachwerkträger besteht die. Verstrebung aus einem Flachband, das aus in seiner Längsrichtung aufeinander folgenden der Länge der Streben entsprechenden Abschnitten mit gegengleichen Längsprofilen besteht. Das Flachband kann einen winkel-, wellen- oder rinnenförmigen Querschnitt aufweisen. Bedingt durch das zur Verstrebung zu verformende Flachband erfordert dieser Fachwerkträger einen relativ hohen Fertigungsaufwand.A generic truss is already known from AT-B-175 370. In this truss, a longitudinal reinforcement is provided for the bracing in order to shorten the buckling length. The introduction of the longitudinal reinforcement increases the manufacturing costs of this truss. In addition, this truss has the disadvantage that ceilings or ceiling trusses can only be stored on the actual trusses. This increases the height of the buildings to be constructed by the height of the truss girders required for structural reasons. According to AT-B-279 127, another truss with a zigzag strut located between two spars is known. With this truss, there is. Bracing from a flat band, which consists of successive in its longitudinal direction sections corresponding to the length of the struts with opposite longitudinal profiles. The flat strip can have an angular, undulating or channel-shaped cross section. Due to the flat band to be deformed for bracing, this truss girder requires a relatively high manufacturing effort.

Bezüglich der Bauhöhe weist er die gleichen Nachteile auf wie der Fachwerkträger nach der AT-B-175370. In der DE-A-1 961 696 ist ein Bauträger und dessen Herstellung beschrieben, der aus einer Grundschiene besteht, auf der ein zickzackförmig ausgebildeter Steg befestigt ist. Mit den mit Abflachungen versehenen Spitzen des Steges kann ein Fußbodenbelag verbunden werden. Der Fußbodenbelag soll hierbei die statische Funktion eines Obergurtes übernehmen. Hierzu ist es erforderlich, daß der Fußbodenbelag mit jeder Spitze des Steges verbunden wird, was die Gesamtkonzeption relativ kompliziert gestaltet und einen verhältnismäßig großen Montageaufwand erfordert. Auch bei diesem Bauträger ergibt das Einbringen einer Decke eine relativ große Bauhöhe.In terms of height, it has the same disadvantages as the truss girder according to AT-B-175370. DE-A-1 961 696 describes a developer and its manufacture, which consists of a base rail on which a zigzag-shaped web is fastened. A floor covering can be connected with the flat ends of the web. The floor covering should take over the static function of an upper chord. For this purpose, it is necessary that the floor covering is connected to each tip of the web, which makes the overall concept relatively complicated and requires a relatively large amount of installation work. With this developer, too, the installation of a ceiling results in a relatively large overall height.

Die Aufgabe der Erfindung besteht darin, ein Verfahren zur einfachen Herstellung eines Fachwerkträgers aufzuzeigen, durch den eine Integration der Decke eines Gebäudes in die Fachwerkträger innerhalb von deren Bauhöhe ermöglicht wird.The object of the invention is to demonstrate a method for the simple manufacture of a truss, by means of which the ceiling of a building can be integrated into the truss within its overall height.

Erfindungsgemäß erfolgt die Lösung der Aufgabe dadurch, daß vor der Befestigung des Obergurtes an der Verstrebung auf diese eine Deckenlage aus Blech gelegt wird, deren Profilform der der Verstrebung entspricht, wobei die Verstrebung gegebenenfalls aus einem von der Deckenlage abgetrennten streifenförmigen Abschnitt besteht.According to the invention, the object is achieved in that, before the upper flange is attached to the strut, a sheet metal ceiling layer is placed on the strut, the profile shape of which corresponds to that of the strut, the strut optionally consisting of a strip-shaped section separated from the ceiling layer.

Weitere Merkmale der Erfindung werden in den Unteransprüchen beschrieben und nachstehend am Beispiel der in den Zeichnungen dargestellten Fachwerkträger näher erläutert. Es zeigt

  • Figuren 1a und 1b je einen erfindungsgemäßen Fachwerkträger mit voneinander unterschiedlichen Obergurten, jeweils in einer Seitenansicht im teilweisen Schnitt,
  • Figur 2 einen Fachwerkträger nach Figur 1a in einer schaubildlichen Ansich in einer Explosionsdarstellung.
Further features of the invention are described in the subclaims and explained in more detail below using the example of the trusses shown in the drawings. It shows
  • 1a and 1b each a truss according to the invention with different top chords, each in a side view in partial section,
  • Figure 2 shows a truss according to Figure 1a in a diagrammatic view in an exploded view.

Wie in Figur 1a dargestellt, besteht der Fachwerkträger 1 aus einem Untergurt 2 und einem Obergurt 7 sowie einer Verstrebung 6. Der Untergurt 2 weist einen u-förmigen Querschnitt auf und ist so angeordnet, daß die Seitenstege 3, 4 nach unten gerichtet sind. Die Verstrebung 6 ist auf der den Seitenstegen 3, 4 abgewandten Fläche des Mittelstegs 5 des Untergurts 2 befestigt. Auf den dem Untergurt 2 abgewandten zu diesen parallelen Flächenabschnitten 9 der Verstrebung 6 ist der Obergurt 7 befestigt. Der Obergurt 7 weist einen allgemein rechteckigen Querschnitt auf und kann beispielsweise als Blechstreifen od. dgl. ausgebildet sein.As shown in Figure 1a, the truss 1 consists of a lower flange 2 and an upper flange 7 and a strut 6. The lower flange 2 has a U-shaped cross section and is arranged so that the side webs 3, 4 are directed downward. The strut 6 is fastened on the surface of the central web 5 of the lower flange 2 facing away from the side webs 3, 4. The upper chord 7 is fastened on the surface sections 9 of the strut 6 facing away from the lower chord 2 and parallel to them. The upper chord 7 has a generally rectangular cross section and can be designed, for example, as a sheet metal strip or the like.

Die Verstrebung 6 besteht vorzugsweise aus einem ebene Flächenabschnitte aufweisenden Blechstreifen 12, der zickzackförmig ist. Die Verbindung von Untergurt 2 und Obergurt 7 mit der Verstrebung 6 kann mittels Niet- oder Schraubverbindungen erfolgen. Es ist auch möglich, Schweiß- oder Klebverbindungen vorzusehen.The strut 6 preferably consists of a sheet metal strip 12 having flat surface sections, which is zigzag-shaped. The lower flange 2 and upper flange 7 can be connected to the strut 6 by means of riveted or screwed connections. It is also possible to provide welded or adhesive connections.

Der Untergurt 2 ist so ausgebildet, daß er unmittelbar auf Stützsäulen von Skelettkonstruktionen gesteckt werden kann. Vorzugsweise wird der Untergurt 2 so ausgebildet, daß die Seitenstege 3, 4 an den Stützsäulen anliegen. Die Verbindung mit den Stützsäulen kann in an sich bekannter Weise mittels Schraubenbolzen oder aber Nietverbindungen erfolgen. Sofern oberhalb des Fachwerkträgers ein weiteres Geschoß ausgebildet und hierzu auf dem Fachwerkträger weitere Stützsäulen angeordnet werden sollen, kann als Obergurt ein solcher mit einem u-förmigen Querschnitt verwendet werden. Dieser in Figur r 1 b dargestellte Fachwerkträger 1 ist bis auf den Obergurt 8 wie der Fachwerkträger 1 ausgebildet. Der Obergurt 8 ist aber im Querschnitt u-förmig und so angeordnet, daß die Seitenstege 16, 17, nach oben gerichtet sind. Zwischen die Seitenstege 16, 17 können dann Stützsäulen, Ausfachungselemente od. dgl. gesteckt werden. Die Verstrebung 6 ist über die Flächenabschnitte 9 mit dem Mittelsteg 15 des Obergurtes 8 verbunden.The lower flange 2 is designed so that it can be plugged directly onto support columns of skeletal structures. The lower flange 2 is preferably designed such that the side webs 3, 4 abut the support columns. The connection to the support columns can be made in a manner known per se by means of screw bolts or rivet connections. If a further floor is to be formed above the truss and further supporting columns are to be arranged on the truss, one with a U-shaped cross section can be used as the upper chord. This truss 1 shown in FIG. 1b is designed like the truss 1 except for the upper chord 8. The upper flange 8 is, however, U-shaped in cross section and arranged in such a way that the side webs 16, 17 are directed upwards. Support columns, infill elements or the like can then be inserted between the side webs 16, 17. The strut 6 is connected to the central web 15 of the upper flange 8 via the surface sections 9.

In Figur 2 ist ein Fachwerkträger 1 in einer schaubildlichen Ansicht in einer Explosionsdarstellung abgebildet. Der Untergurt 2 kann auf verschieden ausgebildete Stützsäulen 11 einer Skelettkonstruktion 10 aufgesteckt werden. Hiernach wird die als Blechstreifen 12 ausgebildete Verstrebung 6 auf dem Untergurt 2 befestigt. Der Blechstreifen 12 kann als besonderes gefaltetes Blechprofil ausgebildet werden oder aber ein Zuschnitt 14 aus einer Deckenlage 13 sein, die wie die Verstrebung 6 profiliert ist und auf dem Fachwerkträger 1 gelagert werden soll. Wenn eine derartige Deckenlage 13 auf dem Fachwerkträger 1 abgestützt werden soll, wird sie vor Befestigung des Obergurtes 7 mit der Verstrebung 6 auf letztere gelegt. Danach wird der Obergurt 7 fluchtend zum Untergurt 2 auf die Deckenlage 13 gelegt und diese verspannend mit der Verstrebung 6 verbunden. Statt eines Obergurtes 7 kann auch der Schematisch dargestellte Obergurt 8 verwendet werden, so daß die Deckenlage 13 auch in einen Fachwerkträger 1a eingesetzt werden kann.In Figure 2 is a truss 1 in one pictorial view shown in an exploded view. The lower flange 2 can be attached to differently designed support columns 11 of a skeleton construction 10. Thereafter, the strut 6 designed as a sheet metal strip 12 is fastened to the lower flange 2. The sheet metal strip 12 can be formed as a special folded sheet metal profile or can be a blank 14 from a ceiling layer 13, which is profiled like the strut 6 and is to be mounted on the truss 1. If such a ceiling layer 13 is to be supported on the truss 1, it is placed on the latter before the upper chord 7 is fastened with the strut 6. Then the upper chord 7 is placed in alignment with the lower chord 2 on the ceiling layer 13 and this is connected to the strut 6 in a tensioning manner. Instead of a top chord 7, the top chord 8 shown schematically can also be used, so that the top layer 13 can also be inserted into a truss 1 a.

Durch die Integration der Deckenlage 13 in den Fachwerkträger 1, 1a, wird die Bauhöhe eines jeden Geschosses um die Höhe einer sonst erforderlichen Trägerlage verringert.By integrating the ceiling layer 13 in the truss 1, 1a, the overall height of each floor is reduced by the height of an otherwise required support layer.

Die Tritt- und Sichtflächen an den Deckenlagen 13 werden in üblicher Weise durch besonders anzubringende Beplankungen od. dgl. erstellt. Die durch die Profilierung der Deckenlage 13 gebildeten Kanäle können als Versorgungskanäle für Versorgungsleitungen ud. dgl. verwendet werden.The tread and visible surfaces on the ceiling layers 13 are created in the usual way by planks or the like to be attached in particular. The channels formed by the profiling of the ceiling layer 13 can ud as supply channels for supply lines. Like. Be used.
