STAND DER TECHNIKSTATE OF THE ART

Aus den Katalogen " PROLYTE TRAVERSEN SYSTEME", 2008 und " PROLYTE GROUP, BLACKBOOK, TECHNICAL MATTERS", 2015 der Firma Prolyte sind Fachwerkträgereinrichtungen der eingangs genannten Art bekannt. Derartige Fachwerkträgereinrichtungen werden hauptsächlich im Bereich der Veranstaltungstechnik eingesetzt, um beispielsweise temporäre Bühnen mit Überdachungen, Messe- und Präsentationsstände aufzubauen. Die Obergurte, Untergurte, Diagonalen und Pfosten zur Bildung der Fachwerktragstruktur bestehen aus Rundrohren und aus dem Material Aluminium. Die Verbindung der einzelnen Bauteile erfolgt über eine Schweißverbindung. Auch für die horizontalen Querpfosten wird Rundaluminiummaterial eingesetzt. Daher können an diese Querpfosten keine Anbauteile wie Adapter oder ähnliches montiert werden oder es ist erheblicher Aufwand erforderlich Anschlussmöglichkeiten zu schaffen. Auch an den Verbindereinheiten der Gurte sind keine Anschlussmöglichkeiten für weitere Bauteile gegeben. Daher ist es praktisch nicht möglich derartige Fachwerkträgervorrichtungen kompatibel mit vorhandenen modularen Gerüstsystemen zu kombinieren und hohe Traglasten zu gewährleisten. Da die bekannten Fachwerkträgervorrichtungen aus Aluminium bestehen ist die Tragfähigkeitsgrenze rasch erreicht.From the catalogs " PROLYTE TRAVERSEN SYSTEME ", 2008 and " PROLYTE GROUP, BLACKBOOK, TECHNICAL MATTERS ", 2015 Prolyte truss support devices of the type mentioned are known. Such lattice girder facilities are mainly used in the field of event technology, for example to build temporary stages with roofs, trade fair and presentation stands. The top chords, bottom chords, diagonals and posts to form the truss structure consist of round tubes and aluminum. The individual components are connected via a welded connection. Round aluminum material is also used for the horizontal cross posts. Therefore, no add-on parts such as adapters or the like can be mounted on these cross posts, or it requires considerable effort to create connection options. There are also no connection options for other components on the connector units of the belts. Therefore, it is practically not possible to combine such truss support devices with existing modular scaffolding systems and to guarantee high payloads. Since the known truss support devices are made of aluminum, the load capacity limit is reached quickly.

Aus der EP 2 253 764 A2 ist eine ebene Fachwerktragstruktur bekannt, die aus Einzelteilen montiert werden muss und zum Aufbau einer Überbrückung und/oder Tragkonstruktion eingesetzt werden kann. Aufgrund der Geometrie dieser Fachwerkträgervorrichtung ist eine Kompatibilität mit bestehenden Modulgerüsten möglich.From the EP 2 253 764 A2 a flat truss structure is known, which must be assembled from individual parts and can be used to build a bridge and / or support structure. Due to the geometry of this truss support device, compatibility with existing module scaffolds is possible.

Als bestehendes Modulgerüst kommt beispielsweise das seit Jahrzehnten bekannte und bewährte "Allround-Gerüstsystem" der Firma Layher in Betracht, das sich als synonym für Modulgerüste am Markt etabliert hat. Dieses Gerüstsystem ist äußerst variabel und vielfältig einsetzbar. Dieses Gerüst kann bei komplizierten Grundrissen und Strukturen aufgrund seiner Variabilität problemlos eingesetzt werden. Die Abfangung sehr großer Lasten oder die Überbrückung großer Spannweiten mit einem derartigen Modulgerüst ist jedoch nur in bestimmten Grenzen verwirklichbar, da Standardsystembauteile eingesetzt werden. In den Bereichen, in den das Modulgerüst aufgrund der hohen Lasten oder hohen Spannweiten an seine Grenzen stößt wird beispielsweise der aus der EP 2 253 764 A2 bekannte Fachwerkträger als Überbrückungs- und/oder Tragkonstruktion eingesetzt, der kompatibel mit den Systemmaßen des Modulgerüsts zum Anschließen von Modulgerüstbauelementen ausgebildet ist.The existing modular scaffolding, for example, is the well-known and proven "all-round scaffolding system" from Layher, which has become synonymous with modular scaffolding on the market. This scaffolding system is extremely variable and versatile. Due to its variability, this scaffold can be used without any problems with complicated floor plans and structures. The interception of very large loads or the bridging of large spans with such a modular scaffold can, however, only be achieved within certain limits, since standard system components are used. In areas where the modular scaffold reaches its limits due to the high loads or wide spans, for example, that from the EP 2 253 764 A2 known truss girder used as a bridging and / or supporting structure, which is designed to be compatible with the system dimensions of the modular scaffolding for connecting modular scaffolding components.

In der US 3 587 125 A und in der US 6 499 266 B1 ist ein Fachwerkträgersystem der eingangs genannten Art beschrieben.In the US 3,587,125 A. and in the US 6 499 266 B1 is described a truss system of the type mentioned.

In der US 3 587 125 A sind zudem Anschlusseinheiten für Geländerpfosten beschrieben, die an die Gurte des Fachwerkträgers angeschlossen sind, wobei dieser Anschluss nicht geeignet ist, hohe Lasten aufzunehmen.In the US 3,587,125 A. connection units for railing posts are also described, which are connected to the straps of the truss, this connection is not suitable for absorbing high loads.

In der GB 2 366 590 A ist ein Fachwerkträger mit Gurten, Pfosten, Querpfosten und Diagonalen beschrieben, die aus Rechteckhohlprofilen bestehen. An den Enden der Gurte sind Verbindereinheiten vorhanden. Alles Profile und die Verbindereinheiten weisen eine schienenförmige Längsnut auf, welche eine Anschlusseinheit für weitere Elemente formt.In the GB 2 366 590 A. is a truss with straps, posts, cross posts and diagonals described, which consist of rectangular hollow profiles. There are connector units at the ends of the straps. All profiles and the connector units have one rail-shaped longitudinal groove, which forms a connection unit for further elements.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Der vorliegenden Erfindung liegt die Aufgabe beziehungsweise das technische Problem zugrunde, ein Fachwerktragsystem zum Aufbau einer Tragkonstruktion, insbesondere in Kombination mit bestehenden Bauelementen eines modularen Gerüßtsystems bereit zu stellen, das erweitere Anwendungs- und Einsatzmöglichkeiten aufweist, hohe Traglasten und die Überbrückung großer Spannweiten gewährleistet, einfache Anschlussmöglichkeiten weiterer Bauteile, insbesondere Bauteile eines Modulgerüstes bietet, wirtschaftlich hergestellt werden kann und eine einfache Montage beziehungsweise Demontage gewährleistet.The present invention is based on the object or the technical problem of providing a truss support system for building a support structure, in particular in combination with existing components of a modular framework system, which has further application and application options, ensures high load capacities and bridging large spans, simple Possibility of connecting other components, in particular components of a modular scaffold, can be manufactured economically and ensures simple assembly and disassembly.

Das erfindungsgemäße Fachwerktragsystem der eingangs genannten Art ist durch die Merkmale des unabhängigen Anspruchs 1 gegeben. Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der von dem unabhängigen Anspruch 1 direkt oder indirekt abhängigen Ansprüche.The truss system according to the invention of the type mentioned is given by the features of independent claim 1. Advantageous refinements and developments are the subject of the claims which are directly or indirectly dependent on independent claim 1.

Das erfindungsgemäße Fachwerktragsystem zeichnet sich demgemäß dadurch aus, dass zumindest eine, insbesondere mehrere, in Querrichtung verlaufende Adaptereinheiten als weitere Systemteile vorhanden sind, wobei die Adaptereinheit eine Grundplatte und zwei rechtwinklig zur Grundplatte verlaufende, parallel beabstandet angeschlossene Stege aufweist, deren lichter Innenabstand im Wesentlichen der Querschnittsbreite des Querpfostens entspricht.The truss support system according to the invention is accordingly characterized in that at least one, in particular several, transverse adapter units are provided as further system parts, the adapter unit having a base plate and two parallel spaced webs running at right angles to the base plate, the internal clearance of which is essentially that Cross-sectional width of the cross post corresponds.

Durch die Ausbildung der Querpfosten zwischen den Obergurten und zwischen den Untergurten mit den Anschlusseinheiten ist es problemlos möglich, auf der ebenen Außenwandung des Querpfostens die Adaptereinheiten anzuschließen, die einen Anschluss weiterer Bauteile ermöglichen. Dasselbe trifft auf die Anschlusseinheiten der Verbindungseinheiten der Gurte zu, sodass auch im Bereich dieser Verbindereinheiten Adaptereinheiten zum Anschluss weiterer Bauteile problemlos angeschlossen werden können. Die horizontal verlaufenden Rechteckrohre als Aussteifungsorgan mit integrierten Ausnehmungen ermöglichen, dass Anbauteile jeglicher Art daran angebracht und befestigt werden können. Die im Stand der Technik bekannten Rundrohre hätten eine zu geringe Auflagefläche als Rechteckrohre, die die Ausgestaltung von Anbauteilen aufwendig gestaltet, wodurch schnell eine wirtschaftlich nicht mehr zu vertretende Grenze überschritten wird. Da an die Verbindungseinheiten für die Ober- und Untergurte ebenso Anschlusseinheiten angeschlossen werden können, sind auch in diesem Bereich Anbauteile jeglicher Art anbringbar, sodass insgesamt als Anbauteile problemlos beispielsweise Systemgerüstbauteile eines modularen Systemgerüsts angeschlossen werden können.Due to the design of the cross posts between the upper chords and between the lower chords with the connection units, it is possible to easily connect the adapter units on the flat outer wall of the cross post, which enable further components to be connected. The same applies to the connection units of the Connection units of the belts, so that adapter units for connecting additional components can also be easily connected in the area of these connector units. The horizontal rectangular tubes as a stiffening element with integrated recesses enable attachments of any kind to be attached and attached. The round tubes known in the prior art would have a too small contact area as rectangular tubes, which makes the design of add-on parts complex, as a result of which an economically unacceptable limit is quickly exceeded. Since connection units can also be connected to the connection units for the upper and lower chords, any type of add-on parts can also be attached in this area, so that, for example, system scaffold components of a modular system scaffold can be easily connected as add-on parts.

Eine konstruktiv besonders einfache Ausgestaltung, die wirtschaftlich hergestellt werden kann, eine einfache und schnelle Montage beziehungsweise Demontage gewährleistet und hohe Anschlusstragfähigkeiten ermöglicht, zeichnet sich dadurch aus, dass die Stege der Adaptereinheit jeweils in ihrem Endbereich eine Steganschlussausnehmung zum Anschluss über eine Bolzen- oder Schraubverbindung an entsprechend fluchtenden Pfostenausnehmungen des Querpfostens aufweisen und die Grundplatte in ihren jeweils in Querrichtung gegenüberliegenden Endbereichen jeweils zwei in Längsrichtung beabstandete Grundplattenausnehmungen aufweist zum Anschluss über eine Bolzen- oder Schraubverbindung an die Verbindereinheitausnehmungen gegenüberliegender Verbindereinheiten der Gurte.A structurally particularly simple design, which can be produced economically, ensures simple and quick assembly and disassembly and enables high connection load capacities, is characterized in that the webs of the adapter unit each have a web connection recess in their end region for connection via a bolt or screw connection have correspondingly aligned post recesses of the cross-post and the base plate in its end regions opposite each other in each case has two longitudinally spaced base plate recesses for connection via a bolt or screw connection to the connector unit recesses of opposite connector units of the belts.

Um einen kompakten, dauerhaft zuverlässigen Anschluss bei gleichzeitig einfacher Montage zu gewährleisten, zeichnet sich eine vorteilhafte Weiterbildung dadurch aus, dass die Länge der Stege im Wesentlichen dem lichten Innenabstand der Obergurte/Untergurte entspricht, wobei sich eine weitere vorteilhafte in Kombination wirkende Ausgestaltung dadurch auszeichnet, dass die Länge der Grundplatte im Wesentlichen dem Abstand der Außenseite der Obergurte/Untergurte entspricht, wodurch die Grundplatte auf beiden gegenüberliegenden Endbereichen einen Überstand über den stirnseitigen Endbereich der Stege aufweist.In order to ensure a compact, permanently reliable connection with simple assembly at the same time, an advantageous further development is characterized in that the length of the webs essentially corresponds to the inside clearance of the upper and lower chords, with another advantageous combination acting embodiment is characterized in that the length of the base plate substantially corresponds to the distance from the outside of the upper chords / lower chords, as a result of which the base plate has a projection on the two opposite end regions over the front end region of the webs.

Um genügend Anschlussfläche für mögliche Anbauteile zur Verfügung zu stellen, zeichnet sich eine vorteilhafte Ausgestaltung dadurch aus, dass die Grundplatte in Längsrichtung beidseitig einen seitlichen Überstand über die Stege aufweist.In order to provide sufficient connection area for possible add-on parts, an advantageous embodiment is characterized in that the base plate has a lateral projection on both sides in the longitudinal direction over the webs.

Eine besonders bevorzugte Weiterbildung, die hohe Tragfestigkeiten gewährleistet zeichnet sich dadurch aus, dass jeweils zwischen benachbarten Pfosten jeweils eine steigende und fallende Diagonale an den Ober- und Untergurt angeschlossen/angeschweißt ist.A particularly preferred further development, which ensures high load-bearing capacities, is characterized in that a rising and falling diagonal is connected / welded to the upper and lower chord between adjacent posts.

Insbesondere bei sehr großen Spannweiten ist es vorteilhaft, unterhalb der Fachwerktrageinrichtung oder unterhalb von mehreren miteinander verbundenen Fachwerktrageinrichtungen eine Unterspannung vorzusehen.In the case of very large spans in particular, it is advantageous to provide an undervoltage below the truss support device or below a plurality of truss support devices connected to one another.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

In Fig. 1 ist in einer Perspektive ein Ausführungsbeispiel einer Fachwerkträgereinrichtung 10 dargestellt, die im Rahmen eines Fachwerksystems eingesetzt werden kann um Tragkonstruktionen mit hoher Tragfähigkeit und/oder großer Spannweite umzusetzen, wobei eine Kompatibilität des Anschlusses von weiteren Bauteilen, insbesondere von Bauteilen aus dem bekannten modularen Layher-Allroundgerüstsystems gewährleistet. Ergänzend ist in Fig. 1 ein kartesisches Koordinatensystem dargestellt mit einer Längsrichtung x, einer Querrichtung y und einer Höhenrichtung z.In Fig. 1 In one perspective, an embodiment of a truss support device 10 is shown, which can be used in the framework of a truss system to implement support structures with a high load-bearing capacity and / or a wide span, with compatibility of the connection of further components, in particular components from the known modular Layher all-round scaffolding system guaranteed. Supplementary is in Fig. 1 a Cartesian coordinate system shown with a longitudinal direction x, a transverse direction y and a height direction z.

Die Fachwerkträgereinrichtung 10 weist zwei in Längsrichtung x durchlaufend vorhandene, in Querrichtung y mit dem Systemmaß S2 parallel beabstandete Obergurte 12 und zwei durchlaufend in Längsrichtung x angeordnete in Querrichtung y mit dem Systemmaß S2 parallel beabstandete und zu den Obergurten mit dem Systemmaß S3 beabstandete Untergurte 14 auf. Zwischen den in einer Ebene x, z liegenden Obergurten 12 und Untergurten 14 ist eine Fachwerkstruktur vorhanden, die aus steigenden und fallenden Diagonalen 16.1, 16.2 und dazwischen angeordneten Pfosten 18 besteht. Im Bereich zwischen den beiden Obergurten 12 beziehungsweise beiden Untergurten 14 ist eine ebene Fachwerkstruktur x, y vorhanden, die Querdiagonalen 20 und alternierend Querpfosten 22, 22.1 aufweist.The truss girder device 10 has two upper chords 12 which are continuous in the longitudinal direction x and are spaced apart in the transverse direction y with the system dimension S2 and two continuously arranged in the longitudinal direction x in the transverse direction y with the system dimension S2 and are spaced from the upper chords with the system dimension S3 . Between the upper chords 12 and lower chords 14 lying in a plane x, z there is a framework structure consisting of rising and falling diagonals 16.1, 16.2 and posts 18 arranged therebetween. In the area between the two upper chords 12 and two lower chords 14, there is a flat truss structure x, y which has transverse diagonals 20 and alternating transverse posts 22, 22.1.

Der Abstand zwischen Obergurt 12 und Untergurt 14 in einer Ebene ist in Figur 1 mit dem Systemmaß S3 bezeichnet. Der Abstand der Querpfosten in Längsrichtung x im Feldbereich ist mit dem Abstand S1 bezeichnet. Die Systemmaße S1, S2, S3 entsprechen beispielsweise dem Systemmaß eines bestehenden modularen Gerüstsystems.The distance between the upper chord 12 and lower chord 14 in one plane is in Figure 1 designated with the system dimension S3. The distance of the cross posts in the longitudinal direction x in the field area is S1 designated. The system dimensions S1, S2, S3 correspond, for example, to the system dimension of an existing modular scaffolding system.

Im jeweiligen Stirnendbereich der Obergurte 12 und der Untergurte 14 sind Verbindereinheiten 40.1 beziehungsweise 40.2 angeschlossen, die ermöglichen, dass in Längsrichtung x benachbart vorhandene Fachwerkträgereinrichtungen 10 miteinander gekoppelt werden können.In the respective front area of the upper chords 12 and the lower chords 14, connector units 40.1 and 40.2 are connected, which enable that truss support devices 10 which are adjacent in the longitudinal direction x can be coupled to one another.

Der Unterschied zu bekannten Fachwerkträgereinrichtungen 10 besteht darin, dass die Querpfosten 22, 22.1 als Rechteckhohlprofile ausgebildet sind, während hingegen sämtliche übrigen Bauteile wie Obergurt 12, Untergurt 14, Diagonalen 16.1, 16.2, Pfosten 18, Querdiagonalen 20 als Rundrohrprofile ausgebildet sind. Zudem weist jeder Querpfosten 22 in seinem Endbereich in dem vertikal z ausgerichteten Steg eine Anschlussausnehmung 24 auf. Die Anschlussausnehmung 24 ist dabei so ausgebildet, dass in Längsrichtung x ein Anschlussmittel wie beispielsweise eine Schraube oder ein Bolzen hindurchgeführt werden kann. Des Weiteren sind an den Verbindereinheiten 40.1, 40.2 jeweils eine Verbindereinheitausnehmung 42 vorhanden, die in Höhenrichtung z durchgehend verläuft. Diese Ausgestaltung - Querdiagonale 20 als Rechteckhohlprofile mit Anschlussausnehmung 24 und Verbindereinheit 40.1, 40.2 mit Verbindereinheitausnehmungen 42 - ist nicht bekannt.The difference to known truss girder devices 10 is that the cross posts 22, 22.1 are designed as rectangular hollow profiles, while, on the other hand, all other components such as the top chord 12, bottom chord 14, diagonals 16.1, 16.2, post 18, cross diagonals 20 are designed as round tube profiles. In addition, each cross post 22 has a connection recess 24 in its end region in the vertically z-aligned web. The connection recess 24 is designed such that a connection means such as a screw or a bolt can be passed through in the longitudinal direction x. Furthermore, a connector unit recess 42 is provided on the connector units 40.1, 40.2, which runs continuously in the height direction z. This configuration - transverse diagonal 20 as a rectangular hollow profile with connection recess 24 and connector unit 40.1, 40.2 with connector unit recesses 42 - is not known.

Durch diese Ausgestaltung ist es möglich, die erfindungsgemäße Fachwerkträgereinrichtung 10 in Tragkonstruktionen einzubinden, die eine variable Einsatzsituation erlauben und gleichzeitig ermöglichen, hohe Traglasten bei großen Spannweiten umzusetzen. Gleichzeitig können über weiter unten beschriebene anzuschließende Adaptereinheiten 30 weitere Anschlussbauteile, insbesondere beispielsweise Systemgerüstbauteile oder andere Tragprofile 80 problemlos - abgestimmt auf den jeweiligen Einsatzzweck - angeschlossen werden.This configuration makes it possible to incorporate the truss support device 10 according to the invention in supporting structures which permit a variable application situation and at the same time enable high load capacities to be implemented with large spans. At the same time, further connection components, in particular, for example, system scaffold components or other support profiles 80, can be connected without problems — matched to the respective intended use — via adapter units 30 to be connected, which are described below.

Fig. 2 zeigt grundsätzlich die einfachen Anschlussmöglichkeiten von unterschiedlichen Adaptereinheiten 30 an den Querpfosten 22, wobei die Adaptereinheiten 30 durch variable Adapteranschlusseinheiten 44.1, 44.2 den Anschluss weiterer Bauteile wie beispielsweise Trägerprofile 80 oder Gerüststiele 82 ermöglichen. Fig. 2 basically shows the simple connection options of different adapter units 30 to the cross posts 22, the adapter units 30, by means of variable adapter connection units 44.1, 44.2, making it possible to connect further components such as, for example, support profiles 80 or scaffolding posts 82.

Ausführungsbeispiele von möglichen Adaptereinheiten 30 sind in den Figuren 3, 4 und 5 dargestellt.Exemplary embodiments of possible adapter units 30 are shown in FIGS Figures 3 , 4th and 5 shown.

Gemäß Figur 3a bis 3d weist die Adaptereinheit 30 eine Grundplatte 32 auf, an die unterseitig zwei parallel beabstandete Stege 34 angeschlossen beziehungsweise angeschweißt sind deren lichter Innenabstand IA im Wesentlichen geringfügig größer ist als die Breite B des Querpfostens 22. Die Länge L1 der Stege 34 ist im Wesentlichen geringfügig kleiner als der lichte Innenabstand IA der Obergurte 12 beziehungsweise der Untergurte 14 der Fachwerkträgereinrichtung 10. Die Länge L2 der Grundplatte 32 (in Querrichtung y gesehen) entspricht im Wesentlichen dem Abstand der Außenseiten gegenüberliegender Obergurte 12 beziehungsweise Untergurte 14.According to Figure 3a to 3d The adapter unit 30 has a base plate 32, to which two parallel spaced webs 34 are connected or welded on the underside, the clear internal spacing IA of which is essentially slightly larger than the width B of the transverse post 22. The length L1 of the webs 34 is essentially slightly smaller than the clear internal clearance IA of the upper chords 12 or the lower chords 14 of the truss girder device 10. The length L2 of the base plate 32 (viewed in the transverse direction y) corresponds essentially to the distance between the outer sides of the opposing upper chords 12 or lower chords 14.

Im jeweiligen gegenüberliegenden Endbereich der Stege 34 sind Steganschlussausnehmungen 36 vorhanden. Im jeweilig gegenüberliegenden Endbereich der Grundplatte 32 sind jeweils zwei in Längsrichtung x beabstandete Grundplattenausnehmungen 38 vorhanden.In the respective opposite end area of the webs 34 there are web connection recesses 36. In the respective opposite end region of the base plate 32 there are two base plate recesses 38 spaced apart in the longitudinal direction x.

Durch die beschriebene geometrische Ausgestaltung der Adaptereinheit 30 ist es montagetechnisch problemlos möglich diese von oben her oder von unten her auf den Querpfosten 22 aufzusetzen, wodurch bereits ein gewisser Formschluss erzielt wird und die aufgesetzte Adaptereinheit 30 durch eine Bolzenverbindung (siehe Fig. 6) zu sichern, da die Ausnehmungen 36 der Adaptereinheit 30 im auf den Querpfosten 22 aufgesetzten Zustand mit den Anschlussausnehmungen 24 des Querpfostens 22 fluchten. Dadurch ist ein einfacher, sicherer und tragfähiger Anschluss gegeben.Due to the geometric design of the adapter unit 30 described, it is easy to mount it from above or from below onto the cross post 22 in terms of assembly technology, which already achieves a certain form fit and the attached adapter unit 30 by means of a bolt connection (see Fig. 6 ) to secure, since the recesses 36 of the adapter unit 30 are in alignment with the connection recesses 24 of the cross post 22 when placed on the cross post 22. This provides a simple, safe and stable connection.

Die in Fig. 3 dargestellte Adaptereinheit 30 stellt die Grundlage für die konstruktive Ausgestaltung von Varianten dieser Adaptereinheit 30 zur Verfügung.In the Fig. 3 The adapter unit 30 shown provides the basis for the design of variants of this adapter unit 30.

Eine erste Ausführungsvariante ist in Fig. 4 dargestellt. Diese zeichnet sich dadurch aus, dass im jeweiligen Endbereich (in Querrichtung y) mittig eine erste Adaptereinheit 44.1 vorhanden ist, die als Rohrprofil ausgebildet ist und die Möglichkeit eröffnet, ein Rundrohrprofil, beispielsweise ein Gerüststiel eines Systemgerüsts, aufzustecken. Der Abstand der Anschlusseinheiten 44.1 in Querrichtung y kann als Systemmaß S2 ausgebildet sein, das als Systemmaß eines anschließbaren modularen Gerüstsystems vorgegeben sein kann.A first variant is in Fig. 4 shown. This is characterized in that in the respective end region (in the transverse direction y) there is a first adapter unit 44.1 in the center, which is designed as a tubular profile and opens up the possibility of attaching a round tubular profile, for example a scaffold post of a system scaffold. The distance between the connection units 44.1 in the transverse direction y can be designed as a system dimension S2, which can be specified as a system dimension of a connectable modular scaffolding system.

Fig. 5 zeig eine zweite Ausführungsvariante einer Adaptereinheit 30 die einen Anschluss von Tragprofilen 80 (siehe Fig. 2) ermöglicht. Hierzu sind oberseitig der Grundplatte 32 zwei parallel in Längsrichtung x beabstandete Anschlusseinheiten 44.2 angeschlossen beziehungsweise angeschweißt, die als Laschen ausgebildet sind, in deren oberen Endbereich beispielsweise über eine Bolzen- oder Schraubverbindung 70, 72 oder das Tragprofil 80 gelenkig angeschlossen werden kann. Fig. 5 show a second embodiment of an adapter unit 30 that connects support profiles 80 (see Fig. 2 ) enables. For this purpose, two connection units 44.2, which are spaced apart in parallel in the longitudinal direction x and are designed as tabs, are connected or welded on the upper side of the base plate 32, the upper end region of which can be connected in an articulated manner, for example via a bolt or screw connection 70, 72 or the support profile 80.

Es sind noch weitere Adapteranschlusseinheiten 44 denkbar, die auf die Anschlussgeometrie des jeweils anzuschließenden Bauteils abgestimmt sind. Insoweit sind die Anschlussmöglichkeiten an die Fachwerkträgereinrichtung 10 über die Adaptereinrichtung 30 mit entsprechend ausgebildeten Adapteranschlusseinheiten 44 in vielfältiger Art und Weise möglich und gegeben, sodass ein variabler und kompatibler Einsatz der Fachwerkträgereinrichtung 10 in die ihr umgebende Tragstruktur möglich ist.Further adapter connection units 44 are also conceivable, which are matched to the connection geometry of the component to be connected in each case. In this respect, the connection options to the truss support device 10 via the adapter device 30 with correspondingly designed adapter connection units 44 are possible and given in a variety of ways, so that a variable and compatible use of the truss support device 10 in the surrounding supporting structure is possible.

Durch die beschriebene geometrische Ausgestaltung der Grundplatte 32 und der Stege 34 weist die Grundplatte 32 gegenüber den Stegen 34 in ihrem jeweiligen Stirnendbereich in Querrichtung y einen Überstand ÜY und Längsrichtung x einen Überstand ÜX auf, der erlaubt, dass unterschiedlichste Anschlussadaptereinheiten 44 auf der Grundplatte 32 zum Anschluss weiterer Bauteile vorhanden sein können.Due to the described geometrical configuration of the base plate 32 and the webs 34, the base plate 32 has a projection UY and a projection ÜX in the respective front end region in the respective front end area in the transverse direction y and longitudinal projection x which allows that A wide variety of connection adapter units 44 can be present on the base plate 32 for connecting further components.

In Fig. 6 ist weiterhin dargestellt, dass auch im Bereich der Verbindereinheiten 40.1, 40.2 der Obergurte 12 eine der oben beschriebenen Adaptereinheiten 30 angeschlossen werden kann. Dies ist dadurch möglich, da die Verbindereinheiten 40.1, 40.2 eine Verbindereinheitausnehmung 42 aufweisen, die in Höhenrichtung z verläuft. Der Anschluss der entsprechenden Verbindereinheit 40.1, 40.2 der Gurte 12 oder 14 ist in Fig. 7 näher dargestellt. Die Verbindereinheiten 40.1, 40.2 weisen einen ersten Bereich auf, der in den Hohlprofilraum des jeweiligen Obergurtes 12 eingeschoben ist. Die Obergurte 12 weisen in diesem eingeschobenen Bereich Langlöcher 46 auf die ermöglichen, dass der eingeschobene Bereich der Verbindereinheiten 40.1 beziehungsweise 40.2 mittels einer Schweißverbindung an den Gurt 12 angeschlossen werden können. Im über dem Stirnbereich auskragenden Bereich sind im dargestellten Ausführungsbeispiel parallel beabstandete Verbindungslaschen 48.1 beziehungsweise 48.2 vorhanden, die jeweils eine im Verbindungszustand fluchtende Verbindungslaschenausnehmungen 47 aufweisen, durch die hindurch eine Bolzenverbindung 49 geführt wird, zum gelenkigen Anschluss benachbarter Fachwerkträgereinrichtungen 10. Gleichzeitig weist jede Verbindereinheit 40.1, 40. 2 eine Verbindereinheitausnehmung 42, verlaufend in Höhenrichtung z auf, die so in Längsrichtung x beabstandet sind, dass bei aufgesetzter Adaptereinheit 30 die Grundplattenausnehmungen 38 mit den Verbindereinheitausnehmungen 42 fluchten und über eine Schraubverbindung 72 (siehe Fig. 6) eine gegen abheben gesicherte Verbindung zwischen den Fachwerkträgereinrichtungen 10 und der Adaptereinheit 30 hergestellt werden kann.In Fig. 6 it is also shown that one of the adapter units 30 described above can also be connected in the area of the connector units 40.1, 40.2 of the upper chords 12. This is possible because the connector units 40.1, 40.2 have a connector unit recess 42 which runs in the height direction z. The connection of the corresponding connector unit 40.1, 40.2 of the belts 12 or 14 is in Fig. 7 shown in more detail. The connector units 40.1, 40.2 have a first area which is pushed into the hollow profile space of the respective upper chord 12. The upper straps 12 have elongated holes 46 in this inserted area, which enable the inserted area of the connector units 40.1 or 40.2 to be connected to the strap 12 by means of a welded connection. In the illustrated embodiment, in the embodiment projecting over the end region, there are parallel spaced connecting lugs 48.1 or 48.2, each of which has a connecting lug recess 47 which is aligned in the connected state and through which a bolt connection 49 is guided, for the articulated connection of adjacent truss support devices 10. At the same time, each connector unit 40.1, 40. 2 a connector unit recess 42, running in the height direction z, which are spaced apart in the longitudinal direction x in such a way that when the adapter unit 30 is attached, the base plate recesses 38 are aligned with the connector unit recesses 42 and via a screw connection 72 (see Fig. 6 ) a connection secured against lifting off can be established between the truss support devices 10 and the adapter unit 30.

Dabei ist hinsichtlich der Geometrie der Anordnung der Adaptereinheit 30 im Bereich der Verbindereinrichtungen 40.1, 40.2 ein Systemmaß S2 zum nächsten Querpfosten 22 der links und rechts anschließenden Fachwerkträgereinrichtung 10 gegeben, die wiederum dem Systemmaß eines modularen Gerüsts entspricht. Die durch den Endbereich der Fachwerkträgereinrichtung 10 angeordneten Querpfosten 22.1 weisen diesbezüglich eine geringere Breite B (in Längsrichtung x) auf, um das Aufsetzen der Adaptereinheit 30 in dem Bereich zwischen den beiden Querpfosten 22.1 benachbarter Fachwerkträgereinrichtungen 10 zu ermöglichen.With regard to the geometry of the arrangement of the adapter unit 30 in the area of the connector devices 40.1, 40.2, there is a system dimension S2 to the next transverse post 22 of the truss support device 10 adjoining on the left and right, which in turn corresponds to the system size of a modular scaffold. In this regard, the cross posts 22.1 arranged through the end region of the truss support device 10 have a smaller width B (in the longitudinal direction x) in order to enable the adapter unit 30 to be placed in the area between the two cross posts 22.1 of adjacent truss support devices 10.

Somit steht insgesamt eine Konstruktion zur Verfügung, bei der oberseitig und/oder unterseitig an den Querpfosten 22 zwischen den Obergurten 12 oder Untergurten 14 jeweils Adaptereinheiten 30 in Längsrichtung beabstandet in einem Systemmaß S1 angeschlossen werden kann, wobei das Systemmaß S1 kompatibel mit einem bestehenden modularen Gerüstsystem ist, sodass die Fachwerkträgereinrichtung 10 oder eine Mehrzahl gekoppelter Fachwerkträgereinrichtungen 10 problemlos in eine umgebende Konstruktion mit einem modularen Gerüstsystem eingebunden werden können. Gleichzeitig können jedoch auch andere Systembauteile wie Tragprofile 80, Lagerprofile oder dergleichen problemlos durch entsprechende Ausgestaltung der Adapteranschlusseinheiten 44 der Adaptereinheit 30 angeschlossen werden. Dies gewährleistet eine hohe Variabilität und Kompatibilität zum Einbau der erfindungsgemäßen Fachwerkträgereinrichtung 10 in zu erstellende Tragkonstruktionen.Thus, there is a total of a construction available in which adapter units 30 can be connected in the system dimension S1 at the top and / or bottom on the cross posts 22 between the top chords 12 or bottom chords 14, the system dimension S1 being compatible with an existing modular scaffolding system is, so that the truss support device 10 or a plurality of coupled truss support devices 10 can be easily integrated into a surrounding structure with a modular scaffolding system. At the same time, however, other system components such as support profiles 80, bearing profiles or the like can also be connected to the adapter unit 30 without problems by appropriately designing the adapter connection units 44. This ensures a high degree of variability and compatibility for the installation of the truss support device 10 according to the invention in supporting structures to be created.

Sämtliche Anschlüsse der Bauelemente der Fachwerkträgereinrichtung 10 sind im Ausführungsbeispiel geschweißt ausgebildet. Als Material kommt bevorzugt Stahl zum Einsatz.All connections of the components of the framework support device 10 are welded in the embodiment. Steel is the preferred material.

Die Figuren 8a und 8b zeigen einen ersten Einsatzfall einer erfindungsgemäßen Fachwerkträgereinrichtung 10 in Kompatibilität mit bestehenden Gerüstbauteilen. Über die Verbindereinheit 40.1 beziehungsweise 40.2 ist die Fachwerkträgereinrichtung 10 auf einer Lagerkonstruktion 74 gelagert, die an Gerüststielen 28 des modularen Gerüstsystems angeschlossen ist. Gleichzeitig sind über an den Querpfosten 22 angeschlossenen Adaptereinheiten 30 und über den Bereich der Verbindereinheiten 40.1, 40.2 angeschlossenen Adaptereinheiten 30 weitere Gerüststiele 83 angeschlossen, sodass die Fachwerkträgereinrichtung 10 als Abfangkonstruktion für ein oberseitig angeordnetes in Fig. 8 nicht näher dargestelltes modulares Gerüstsystem angesetzt ist.The Figures 8a and 8b show a first application of a truss support device 10 according to the invention in compatibility with existing scaffolding components. The truss support device 10 is mounted on a bearing structure 74, which is connected to scaffolding posts 28 of the modular scaffolding system, via the connector unit 40.1 or 40.2. At the same time are connected via adapter units 30 connected to the cross posts 22 and over the area of the connector units 40.1, 40.2 Adapter units 30 further scaffold posts 83 are connected, so that the truss support device 10 as a support structure for a top arranged in Fig. 8 modular scaffolding system, not shown, is attached.

Fig. 9 zeigt in einer Perspektive den Einsatzfall einer mehrerer miteinander über die Verbindereinheiten 40.1, 40.2 in Längsrichtung x gekoppelte Fachwerkträgereinrichtungen 10 (vier Stück), die im jeweils gegenüberliegenden Endbereich auf einer Lagerkonstruktion 74 gelagert sind. Das aus den mehreren in Längsrichtung x gekoppelten Fachwerkträgereinrichtungen 10 bestehende erfindungsgemäße Fachwerksystem erlaubt es problemlos beispielsweise oberseitig ein Fassadengerüst 52 anzuschließen und unterseitig ein Hängegerüst 50 anzuschließen, wobei durch die gekoppelten Fachwerkträgereinrichtungen 10 sehr große Spannweiten überbrückt werden können, die mittels des dargestellten modularen Gerüstsystems nicht freitragend überbrückt werden können. Fig. 9 shows in a perspective the application of one of a plurality of truss support devices 10 (four pieces) which are coupled to one another in the longitudinal direction x via the connector units 40.1, 40.2 and which are mounted on a bearing structure 74 in the respectively opposite end region. The truss system according to the invention, consisting of the several truss girder devices 10 coupled in the longitudinal direction x, allows, for example, a facade scaffold 52 to be connected on the top side and a hanging scaffold 50 to be connected on the underside, the coupled truss girder devices 10 being able to bridge very large spans which are not self-supporting by means of the modular scaffolding system shown can be bridged.

Fig. 10 zeigt in einer Perspektive ein völlig anderes Einsatzgebiet der erfindungsgemäßen Fachwerkträgereinrichtungen 10, nämlich im Rahmen einer Dachkonstruktion, wobei als statisch tragende Randträger der Dachkonstruktion eine Vielzahl von miteinander in Längsrichtung x über die Verbindereinheiten 40.1, 40.2 gekoppelten Fachwerkträgereinrichtungen 10 eingesetzt werden, die im Endbereich auf Lagerkonstruktionen 74 gelagert sind, wobei auf den zwischen den Obergurten 12 verlaufenden Querpfosten 22 Adaptereinheiten 30 angeschlossen sind, die oberseitig Adapteranschlusseinheiten 44.2 aufweisen, zum gelenkigen Anschluss von Dachbindern 54. Dieses Ausführungsbeispiel zeigt, dass unter Einsatz der erfindungsgemäßen Fachwerkträgereinrichtungen 10 in Verbindung mit den Adaptereinheiten 30 und entsprechenden Adapteranschlusseinheiten 44.2 Dachkonstruktionen mit großer Spannweite in Längsrichtung x und durch entsprechende Ausbildung der Dachbinder 54 auch in Querrichtung y problemlos umgesetzt werden können. Fig. 10 shows in a perspective a completely different field of application of the truss support devices 10 according to the invention, namely in the context of a roof structure, wherein a plurality of truss support devices 10 which are coupled to one another in the longitudinal direction x via the connector units 40.1, 40.2 and which are used in the end region on bearing constructions are used as statically supporting edge supports of the roof construction 74 are mounted, 22 adapter units 30 are connected to the cross posts running between the upper chords 12 and have adapter connection units 44.2 on the upper side for the articulated connection of roof trusses 54. This exemplary embodiment shows that using the truss support devices 10 according to the invention in connection with the adapter units 30 and corresponding adapter connection units 44.2 roof structures with a large span in the longitudinal direction x and by appropriate design of the roof truss 54 also in the transverse direction y can be replaced.

Die Figuren 12 und 13 zeigen den Einsatz erfindungsgemäßer Fachwerkträgereinrichtungen 10 in Verbindung mit Adaptereinheiten 30 und Adapteranschlusseinheiten 44.2 im Rahmen einer Dachkonstruktion, bei der an die Anschlusseinheiten 44.2 als Laschenkonstruktion Tragprofile 80 gelenkig angeschlossen sind, die als Kederdachprofile ausgebildet sind, das heißt Profile die eine Ausgestaltung mit Nuten haben, in denen Kederdachplanen angeschlossen werden können.The Figures 12 and 13 show the use of truss support devices 10 according to the invention in connection with adapter units 30 and adapter connection units 44.2 in the context of a roof construction, in which support profiles 80 are articulated to the connection units 44.2 as a lug construction, which are designed as keder roof profiles, that is to say profiles which have a design with grooves, in to which keder roof tarpaulins can be connected.

Fig. 11 zeigt eine weitere räumliche Tragstruktur bei der erfindungsgemäße Fachwerkträgereinrichtungen 10 eingesetzt sind. Zur Ausbildung der räumlichen Struktur werden in Eckbereichen Winkelkopplungseinheiten 58 eingesetzt, die im Ausführungsbeispiel die Fachwerkträgereinrichtungen 10 in einem rechten Winkel miteinander kombinieren. Fig. 11 shows a further spatial support structure in the truss support devices 10 according to the invention are used. To form the spatial structure, corner coupling units 58 are used in corner areas, which in the exemplary embodiment combine the truss support devices 10 at a right angle.

Dabei ist es problemlos möglich, zwischen den Fachwerkträgereinrichtungen 10 je nach Bedarf und Erfordernissen zwischen den Fachwerkträgereinrichtungen 10 ebene Gitterfachwerkträger 56 anzuschließen, die Bestandteil der räumlichen Fachwerkstruktur sind. Diese Gitterfachwerkträger 56 werden in dem Ausführungsbeispiel gemäß Fig. 11 an die Pfosten 18 der Fachwerkträgereinrichtungen 10 entsprechend angeschlossen, beispielsweise über klemmbare Lochscheiben und an Gitterfachwerkträgern 56 als Systembauteile eines modularen Systemgerüsts vorhandenen Keilkopfanschlusseinheiten.It is easily possible to connect flat lattice truss girders 56 between the truss girder devices 10, which are part of the spatial truss structure, depending on the needs and requirements of the truss girder devices 10. These lattice truss girders 56 are in accordance with the exemplary embodiment Fig. 11 appropriately connected to the posts 18 of the truss girder devices 10, for example via clampable perforated disks and wedge-head connection units present on system truss girders 56 as system components of a modular system framework.

Fig. 11 zeigt einmal mehr, wie durch den Einsatz der erfindungsgemäßen Fachwerkträgereinrichtungen 10 eine räumlich komplexe Tragstruktur in einfacher Art und Weise umgesetzt werden kann, wobei bekannte modulare Tragbauteile, wie die dargestellten Gitterfachwerkträger 56 problemlos und in dem vorhandenen Gerüstmaß an die Fachwerkträgereinrichtungen 10 angeschlossen werden können.

Fig. 14 zeigt wie die Tragfähigkeit einer Tragkonstruktion unter Einsatz über Verbindungseinheiten 40.1, 40.2 gekoppelter Fachwerkträgereinrichtungen 10 weiter gesteigert werden kann. Es ist beispielsweise möglich, das eine Unterspannung 60 unterseitig an die durch die Fachwerkträgereinrichtungen 10 gebildete Tragkonstruktion angeschlossen wird. Im dargestellten Ausführungsbeispiel besteht die Unterspannung 60 aus einem mittig unterseitig angeordneten Druckpfosten 62 und einem Zugglied 64, das im unteren stirnseitigen Endbereich der Tragstruktur unterseitig an die Fachwerkträgereinrichtung 10 angeschlossen ist und über den Druckpfosten 62 verlaufend vorhanden ist. Durch das Vorsehen einer zusätzlichen Unterspannung 60 lassen sich sehr große Tragspannweiten in einfacher Art und Weise umsetzen. Fig. 14 shows how the load-bearing capacity of a supporting structure can be further increased by using truss support devices 10 coupled via connecting units 40.1, 40.2. It is possible, for example, that an undervoltage 60 is connected on the underside to the supporting structure formed by the framework support devices 10. In the exemplary embodiment shown, the undervoltage 60 consists of a pressure post 62 arranged centrally on the underside and a tension member 64 which is connected on the underside to the truss support device 10 in the lower end region of the support structure and is present running over the pressure post 62. By providing an additional undervoltage 60, very large load spans can be implemented in a simple manner.
