Description

Die Erfindung betrifft einen U-Profil-Träger einer Überdachung, Halle, Tribüne, Treppe oder eines Gerüsts oder Podiums und dergleichen mit einem nach außen offenen U-Profil, das parallel zueinander und zur Längsmittelebene des U-Profils angeordnete und durch eine Querwand verbundene Stützschenkel aufweist, die vorzugsweise an ihren freien Enden Auflageränder für ein Auflageelement, insbesondere für ein Dach, beispielsweise für ein Kassettendach oder für ein Planendach oder für ein Lauf- und/oder Arbeitsflächenelement, insbesondere für einen Gerüstboden oder für dessen, vorzugsweise als Klauen gestaltete, Einhängehilfsmittel aufweist und mit einem einstückig mit dem U-Profil verbundenen Anschlussteil zur Befestigung und Abstützung des U-Profils an einem langgestreckten Tragelement, insbesondere an einem Obergurt eines Gitterträgers oder an einem Gerüstrohr.The invention relates to a U-profile support a canopy, hall, grandstand, stairs or a scaffold or podium and the like with an outwardly open U-profile, the parallel to each other and to the median longitudinal plane of the U-profile and connected by a transverse wall supporting leg has, preferably at their free ends bearing edges for a support element, in particular for a roof, for example for a cassette roof or for a canopy or for a running and / or working surface element, in particular for a scaffold floor or for its, preferably designed as claws, Einhängehilfsmittel having and with an integrally connected to the U-profile connection part for fastening and supporting the U-profile on an elongate support member, in particular on a top flange of a lattice girder or on a scaffolding tube.

Aus der DE 35 42 610 A1 ist ein Schnell-Montage-Hallendach mit einem Kassettendach bekannt geworden, bei dem die Dachhautelemente auf U-profilförmigen Obergurten von in der Praxis auch mit Kassettenträgern bezeichneten Dachbindern aufgelegt und abgestützt sind. Diese Dachbinder haben außer den Obergurten auch Untergurte, Vertikalstäbe und Diagonalstäbe, die in üblicher Stahlbautechnik dimensioniert und zusammengeschweißt sind. Die Obergurte sind als nach oben offene U-Profilstäbe ausgebildet, deren U-Schenkel Vertikalschenkel ausbilden und deren Basis bzw. Grund mit Horizontalstegen gebildet ist, die mit den Vertikalstäben und den Diagonalstäben der Dachbinder verschweißt sind. In Längsrichtung des jeweiligen Dachbinders sind auf dem Grund dessen Obergurtes in der Mitte des Horizontalstegs in bestimmten Abständen nach oben herausragende Sicherungslaschen festgeschweißt. Diese sind für eine Sicherungsöffnung für einen Keil geeignet länger ausgebildet als die Vertikalschenkel des Obergurtes, mit dessen Hilfe die Dachelemente an dem Obergurt festspannbar sind.From the DE 35 42 610 A1 is a fast-mounting hall roof with a cassette roof has become known in which the roof skin elements on U-shaped top chords of in practice also with cassette carriers designated roof trusses are laid up and supported. These roof trusses have in addition to the upper straps and lower straps, vertical bars and diagonal bars, which are dimensioned and welded together in conventional steel construction technology. The upper straps are designed as upwardly open U-profile bars whose U-legs form vertical legs and whose base or base is formed with horizontal webs, which are welded to the vertical bars and the diagonal bars of the roof trusses. In the longitudinal direction of the respective roof truss are at the bottom of the upper flange in the middle of the horizontal bar at certain intervals upwardly outstanding securing tabs welded. These are suitable for a securing opening for a wedge longer than the vertical leg of the upper flange, with the help of which the roof elements are clamped to the upper flange.

Diese Konstruktion hat sich in der Praxis bewährt und ermöglicht eine schnelle Montage bzw. Demontage und ist geeignet, große Spannweiten abzudecken. Allerdings wird für die Montage in jedem Fall ein Kran benötigt. Die vergleichsweise schweren Dachbinder sind mit ihren U-Profilstäben für einen speziellen Einsatz bei Dachkonstruktionen konzipiert. An den Sicherungslaschen können außer den Dachhautelementen auch andere Befestigungselemente, z. B. Geländerhalter gemäß der DE 297 11 346 U1 oder Absturzsicherungs-Hilfsvorrichtungen gemäß der DE 20 2004 001 314 U1 angeschlossen werden. Die hierfür verfügbaren Befestigungspositionen sind jedoch auf die Positionen der fest mit den U-Profilstäben der Obergurte der Dachbinder verschweißten Sicherungslaschen beschränkt.This design has proven itself in practice and allows for rapid assembly and disassembly and is suitable to cover large spans. However, a crane is needed in any case for the assembly. The comparatively heavy roof trusses with their U-profile bars are designed for special use in roof structures. At the securing tabs other fasteners, such. B. railing holder according to the DE 297 11 346 U1 or fall protection auxiliary devices according to the DE 20 2004 001 314 U1 be connected. However, the fastening positions available for this purpose are limited to the positions of the securing straps welded firmly to the U-profile bars of the upper straps of the roof trusses.

Eine alternative Möglichkeit zum Aufbau von Dachkonstruktionen ist beispielsweise aus der DE 100 28 262 A1 bekannt geworden, welche eine Planendachkonstruktion betrifft. Diese Dachkonstruktion ist unter Verwendung von sogenannten Gitterträgern hergestellt, wie sie für Serienteile im Gerüstbau bekannt geworden sind. Diese Dachbinder ausbildenden Gitterträger weisen einen rohrförmigen Obergurt, einen rohrförmigen Untergurt und steigende sowie fallende Rohrdiagonalen wie auch etwa senkrecht zu dem Obergurt und dem Untergurt angeordnete rohrförmige Vertikalstäbe auf. Auf die Obergurte der Gitterträger aufgesetzt ist jeweils eine über die gesamte Länge des jeweiligen Dachbinders verlaufende Anschlussprofileinheit angeschlossen. Diese umfasst ein über die gesamte Länge des Gitterträgers verlaufendes U-Profil, an dem unterseitig und senkrecht dazu rohrförmige Stützstreben angeschweißt sind, an deren von dem U-Profil weg weisenden unteren Enden jeweils eine Gelenk-Rohrkupplung angeschweißt ist. Mithilfe dieser Gelenk-Rohrkupplungen kann die Anschlussprofileinheit auf den Obergurten der Gitterträger wiederlösbar befestigt werden. Bei dieser Konstruktion kann es abhängig von der geometrischen Gestaltung und Anordnung der Rohrdiagonalen und/oder der Vertikalstäbe des Gitterträgers zu Situationen kommen, bei denen die Rohrkupplungen mit einem oder mehreren dieser Rohrdiagonalen und/oder Vertikalstäben kollidieren, so dass dann dort keine Befestigung der Anschlussprofileinheit an dem Gitterträger mittels der Gelenk-Rohrkupplung möglich ist. Dadurch ergibt sich ein erhöhtes Sicherheitsrisiko. Zur Befestigung der Plane des Planendachs an der Anschlussprofileinheit ist in deren U-Profil ein Kantholz eingelassen, dessen Oberseite bündig mit den nach oben weisenden Enden der vertikalen Stege der U-Profileinheit abschließen. Die Plane ist mit Metallklammern an dem Kantholz angetackert und zusätzlich über ein nach unten hutförmig offenes Abdeckprofil gesichert, das wiederum mit einer die Plane durchdringenden und in das Kantholz eingeschraubten Schraube befestigt ist. Diese Art der Befestigung ist vergleichsweise aufwändig.An alternative possibility for the construction of roof structures, for example, from DE 100 28 262 A1 become known, which relates to a roof structure. This roof construction is made using so-called lattice girders, as they have become known for series parts in scaffolding. This roof truss forming lattice girders have a tubular upper flange, a tubular lower flange and rising and falling pipe diagonals as well as approximately vertical to the upper flange and the lower flange tubular vertical rods. Attached to the upper chords of the lattice girders is in each case connected over the entire length of the respective roof truss running connection profile unit. This comprises a extending over the entire length of the lattice girder U-profile, are welded to the underside and perpendicular thereto tubular support struts, at the side facing away from the U-profile lower ends each have a joint pipe coupling is welded. With the aid of these articulated tube couplings, the connection profile unit can be detachably fastened to the upper straps of the lattice girders. In this construction, depending on the geometric design and arrangement of the pipe diagonals and / or the vertical bars of the lattice girder, situations may occur in which the pipe couplings collide with one or more of these pipe diagonals and / or vertical bars, so that then there is no fastening of the connection profile unit the lattice girder by means of the joint pipe coupling is possible. This results in an increased security risk. To fix the tarpaulin of the tarpaulin roof to the terminal profile unit, a square timber is embedded in its U-profile, the upper side flush with the upwardly facing ends of the vertical webs of the U-profile unit. The tarpaulin is with metal brackets angegetackert on the square timber and additionally secured by a down hat-shaped open cover, which in turn is attached to a plank penetrating and screwed into the square timber screw. This type of attachment is relatively expensive.

Eine ähnliche Tragkonstruktion ist aus der DE 91 10 828 U1 bekannt geworden. Dort ist ein U-Profilsteg starr mit einem Ständer verbunden, der wiederum starr mit einer Kupplungshälfte einer Rohrkupplung verbunden ist. An dieser Kupplungshälfte ist über ein Bolzendrehgelenk unverlierbar fest eine Kupplungshalbschale befestigt. Diese Konstruktion weist dieselben Nachteile auf, wie bereits vorstehend im Zusammenhang mit der DE 100 28 262 A1 beschrieben.A similar support structure is from the DE 91 10 828 U1 known. There, a U-profile web is rigidly connected to a stand, which in turn is rigidly connected to a coupling half of a pipe coupling. At this coupling half captive fixed a coupling half shell is fixed on a bolt pivot. This construction has the same disadvantages as already mentioned above in connection with the DE 100 28 262 A1 described.

Ähnlich gestaltete Anschlussprofileinheiten der Anmelderin sind in der Praxis bekannt geworden und zwar für den Einsatz bei Kassettendächern. Zur Befestigung deren Dachelemente sind an dem Grund des U-Profils der Anschlussprofileinheit nach oben herausragende Sicherungslaschen festgeschweißt, so wie bereits vorstehend im Zusammenhang mit der DE 35 42 610 A1 beschrieben, so dass insoweit auch dieselben Nachteile auftreten.Applicants' similarly designed terminal profile units have become known in practice for use with cassette roofs. To attach their roof elements are welded to the bottom of the U-profile of the connection profile unit upwardly outstanding securing tabs, as already above in connection with the DE 35 42 610 A1 described, so that in this respect the same disadvantages occur.

Aus der DE 31 07 416 A1 ist eine Tragkonstruktion für auf- und abbaubare Überdachungen oder Hallen bekannt geworden, bei der sowohl als vertikale Stützen als auch als Dachträger ein I-Profil-Träger mit doppeltem Quersteg eingesetzt wird. Der I-Profil-Träger besteht aus zwei im Abstand parallel zueinander verlaufenden Stegen, die an ihren Enden jeweils mit einer Querwand unter Ausbildung eines kastenförmigen Hohlprofils verbunden sind. An den beiden Enden der Stege ist jeweils ein I-Flansch vorgesehen, dessen Flanschteile sich von der Längsmittelebene des Trägers aus betrachtet senkrecht zu den Stegen nach außen erstrecken und die längs der Kanten der Stege verlaufen. Eine der Querwände erstreckt sich in einem Abstand zu dem zugehörigen I-Flansch im Inneren des Trägers, so dass ein nach außen offener Hohlraum zum Einsetzen einer Holzbohle ausgebildet ist. Die gegenüberliegende Querwand ist unter Ausbildung einer T-förmigen Nut gestaltet. Diese dient zur Aufnahme eines Hammerkopfes einer Hammerkopfschraube, mittels deren an dem I-Profil-Träger ein mit einem Langloch versehenes Bauelement festgelegt werden kann, indem auf die Hammerkopfschraube eine Mutter aufgeschraubt und festgezogen wird. Um auch nicht mit Langlöchern versehene Bauelemente an dem I-Träger-Profil festlegen zu können, kann auch eine rechteckige Klemmplatte vorgesehen sein, durch deren Rundloch die Hammerkopfschraube durchgesteckt ist. Die Montage dieses vergleichsweise schweren I-TrägerProfils ist nicht ohne einen Kran möglich und die an der separat handzuhabenden und zu transportierenden Holzbohle befestigten Dachelemente lassen sich nur aufwändig demontieren.From the DE 31 07 416 A1 has become known a supporting structure for buildable and degradable roofs or halls, in which both vertical supports and as a roof rack I-profile carrier with double cross bar is used. The I-profile carrier consists of two spaced apart parallel webs, which are connected at their ends in each case with a transverse wall to form a box-shaped hollow profile. At the two ends of the webs, an I-flange is provided in each case, the flange portions of which, viewed from the longitudinal center plane of the carrier, extend outwards perpendicular to the webs and extend along the edges of the webs. One of the transverse walls extends at a distance to the associated I-flange in the interior of the carrier, so that an outwardly open cavity for inserting a wooden plank is formed. The opposite transverse wall is designed to form a T-shaped groove. This is used to hold a hammer head of a hammer head screw, by means of which on the I-profile support a provided with a slot component can be set by a nut is screwed and tightened on the hammer head bolt. In order not to be able to define components provided with slots on the I-beam profile, a rectangular clamping plate can also be provided, through the round hole of which the hammer head screw is pushed through. The installation of this comparatively heavy I-beam profile is not possible without a crane and attached to the separately handled and transported wooden plank roof elements can be removed only consuming.

Andere I-Träger-Profile, welche ein Gerüstelement mit einem auswechselbaren Ergänzungsstück betreffend, sind aus der DE-OS 28 50 098 und der DE-OS 28 50 545 bekannt geworden. Diese I-Träger-Profile weisen an ihren flanschseitigen Enden jeweils eine nach außen offene T-förmige Nut auf, in der ein separat handhabbares U-förmiges Zusatzelement eingesetzt werden kann, das zu diesem Zwecke an seinem die beiden U-Schenkel verbindenden Steg mit einem T-förmigen, nach außen weisenden Ansatz versehen ist. Ein solches Zusatzelement kann dazu herangezogen werden, um die Klauen von als Geh- oder Arbeitsflächen dienenden Bohlen oder Rahmentafeln einzuhängen. Derartige Zusatzelemente müssen separat gehandhabt, gelagert und transportiert werden.Similar I-beam with double cross bar are, for example, from DE 30 45 389 C2 known.

Zwischen dieser und den sich daran anschließenden beiden Längsstegen des oberen I-Flansches ist ein nach außen offener Hohlraum ausgebildet, in dem eine Holzbohle eingesetzt und dort mittels Schraubenbolzen gesichert ist. An dieser Holzbohle wird eine Schalungsplatte für den auf- bzw. einzugießenden Beton angenagelt. Der untere I-Flansch umfasst zwei sich in entgegengesetzten Richtungen nach außen erstreckende Flanschteile, die an ihren freien Enden in Längsrichtung durchlaufende Verdickungen aufweisen. Der I-Profil-Träger ist mit Hilfe von zwei Befestigungsklipsen an einem baugleichen jedoch gegenüber dem vorgenannten I-Profil-Träger um 180 Grad vertikal gedrehten I-Profil-Träger mit Hilfe von Schrauben und Muttern befestigt. Die Befestigungsklipse weisen jeweils an einem ihrer Enden im Querschnitt hakenförmig gestaltete Befestigungsschenkel auf, welche die Verdickungen der Flanschteile des unteren I-Flansches übergreifen. Die Montage dieses I-Profil-Trägers ist aufwändig.From the US 4,133,155 A an I-profile beam for Betonabschalungen has become known. This has at its upper and at its lower end in each case an I-flange, the flange portions extend perpendicular to the longitudinal webs outwardly extending and along the edges of the longitudinal webs. Inside this I-profile beam extends perpendicular to its longitudinal webs a transverse wall. Between this and the adjoining two longitudinal webs of the upper I-flange, an outwardly open cavity is formed, in which a wooden plank is used and secured there by means of bolts. At this wooden screed a shuttering plate for the auf- or pouring concrete is nailed. The lower I-flange comprises two flange portions extending outwardly in opposite directions and having longitudinal thickenings at their free ends. The I-profile beam is fastened by means of two fastening clips on a structurally identical but opposite to the aforementioned I-profile beam 180 degrees vertically rotated I-profile beam by means of screws and nuts. The fastening clips each have at one of their ends in cross-section hook-shaped fastening legs, which engage over the thickenings of the flange parts of the lower I-flange. The assembly of this I-profile beam is complex.

Sie haben Obergurte 20, Untergurte 21, Vertikalstäbe 22 und Diagonalstäbe 23. Wegen der Dachneigung stehen die Vertikalstäbe 22 nicht genau senkrecht. Sie werden dennoch als Vertikalstäbe bezeichnet. Diese Gurte 20, 21 und Streben 22, 23 sind zu einem Gitterträger zusammengeschweißt.The roof trusses 12 are designed as a lattice girder 18, preferably made of aluminum, as they are as serial parts in the Scaffolding can be used. They have upper straps 20, lower straps 21, vertical bars 22 and diagonal bars 23. Because of the roof pitch, the vertical bars 22 are not exactly vertical. They are still referred to as vertical bars. These straps 20, 21 and struts 22, 23 are welded together to form a lattice girder.

Auf dem ein Tragelement 46 bildenden, hier rohrförmigen Obergurt 20 des Gitterträgers 18 ist ein erfindungsgemäßer U-Profil-Träger 30 aufgesattelt und dort mithilfe einer als Rohrkupplung gestalteten Anschlusskupplung 60 wiederlösbar befestigt. Der U-Profil-Träger 30 weist ein nach außen offenes U-Profil 35 auf, das parallel zueinander und zur Längsmittelebene 36 des U-Profils 35 angeordnete und durch eine Querwand 37 verbundene Stützschenkel 38.1, 38.2 aufweist, die an ihren freien Enden Auflageränder 39.1, 39.2 für ein Auflageelement 40 aufweisen. Bei dem Auflageelement 40 handelt es sich bei dem in Figur 3 gezeigten Ausführungsbeispiel der Erfindung um Dachhautelemente 41 eines Kassettendachs. Es versteht sich jedoch, dass als Auflageelement 40 auch ein Planendach oder ein Lauf- und/oder Arbeitsflächenelement, insbesondere ein Gerüstboden oder dessen Einhängehilfsmittel 57, wie Klauen und dergleichen vorgesehen sein können, so wie beispielsweise in Figur 4 gezeigt.On the support element 46 forming, here tubular upper flange 20 of the lattice girder 18, an inventive U-profile support 30 is saddled and secured there releasably using a coupling designed as a coupling coupling 60.

Es versteht sich, dass der U-Profil-Träger 30 auch dafür geeignet und bestimmt ist, an anderen Tragelementen, beispielsweise an einem Gerüstrohr mithilfe der Anschlusskupplung 60 befestigt zu werden.The U-profile 35 of the extruded light metal U-profile carrier is formed integrally with a connection part 45, which serves for fastening and supporting the U-profile 35 on the elongate support member 46, here the upper flange 20 of the lattice girder 18. It is understood that the U-profile beam 30 is also suitable and intended for other support elements, for example, to be attached to a scaffold tube using the connection coupling 60.

Der U-Profil-Träger 30 weist eine durch die Querwand 37 begrenzte und in Richtung der Auflageränder 39.1, 39.2 der Stützschenkel 38.1, 38.2 sowie zu deren Innenseiten 42.1, 42.2 hin offene, sich quer zu den Stützschenkeln 38.1, 38.2 erstreckende Führungs-Nut 50 auf. Diese Führungs-Nut 50 ist unter Ausbildung eines Schlitzes 51 durch im Abstand zueinander und längs der Innenseiten 42.1, 42.2 der beiden Stützschenkel 38.1, 38.2 angeordnete und davon ausgehend sich jeweils nach innen zur Längsmittelebene 36 hin erstreckende Nut-Hintergreif-Stege 52.1, 52.2 begrenzt. Die Nut-Hintergreif-Stege 52.1, 52.2 sind hier etwa senkrecht zu den Stützschenkeln 38.1 und 38.2 ausgebildet und liegen hier in einer gemeinsamen Horizontalebene, die hier senkrecht zu der Längsmittelebene 36 steht.The U-profile carrier 30 has a limited by the transverse wall 37 and in the direction of the support edges 39.1, 39.2 of the support legs 38.1, 38.2 and to the insides 42.1, 42.2 out, transverse to the support legs 38.1, 38.2 extending guide groove 50th on. This guide groove 50 is by forming a slot 51 by at a distance from each other and along the inner sides 42.1, 42.2 of the two support legs 38.1, 38.2 arranged and thereof starting in each case inwardly to the longitudinal median plane 36 extending towards groove-engaging ribs 52.1, 52.2 limited , The groove-engaging ribs 52.1, 52.2 are here approximately perpendicular to the support legs 38.1 and 38.2 formed and lie here in a common horizontal plane, which is perpendicular to the longitudinal center plane 36 here.

In contrast to the constructions known from the prior art, this connection coupling 60 can be releasably fastened to the mounting legs 59.1 and 59.2 at several arbitrary positions along the U-profile support 30 in the case of the U-shaped support 30 designed according to the invention. The U-profile support 30 can be fixed by means of the connection coupling 60 on the elongated, here formed as upper flange 20 of a lattice girder 80 support member 46 and is there according to the in the Figures 3 and 4 fastened mounting positions shown. For this purpose, the two mounting legs 59.1 and 59.2 here each as a in the longitudinal direction 62 of the U-profile support 30 extending and over the entire length of the U-profile support continuous mounting rail 63.1, 63.2 designed, to which the fasteners 71.1 and 71.2 of the connection coupling 60 at several arbitrary positions along the U-profile support 30 can be fastened. In this way, the connection coupling 60 can be arranged and fixed at arbitrary positions along the U-profile support 30 for fastening the same to the support element 46 without colliding with adjacent components such as braces. This ensures optimum safety. The coupling half-shell 61 is designed as a light metal extruded profile, in contrast to the known from the prior art coupling half shells.

Die Befestigungsschenkel 59.1 und 59.2 umfassen jeweils Hintergreifflächen 69.1, 69.2 aufweisende Stützelemente 68.1, 68.2, die sich von dem Tragelement 46, hier dem Obergurt 20 weg und zu der das U-Profil 35 aufweisenden Seite des U-Profil-Trägers 30 hin erstrecken und mit deren Hilfe eine seitliche Abstützung von Befestigungsteilen 71.1, 71.2 der Anschlusskupplung 60 erreicht wird, wenn diese unter Befestigung des U-Profil-Trägers 30 an dem Tragelement 46 an dem U-Profil-Träger 30 befestigt ist. Im befestigten Zustand sind also die Befestigungsteile 71.1 und 71.2 der Anschlusskupplung 60 formschlüssig mit den Stützelementen 68.1, 68.2 bzw. mit den Befestigungsschenkeln 59.1, 59.2 verbunden.The fastening legs 59.1 and 59.2 each comprise undercut surfaces 69.1, 69.2 having supporting elements 68.1, 68.2, which extend away from the support element 46, here the upper flange 20 and to the U-profile 35 having side of the U-profile support 30 and with their help a lateral support of fasteners 71.1, 71.2 of the connection coupling 60 is achieved when it is secured by fixing the U-profile support 30 to the support member 46 on the U-profile support 30. In the attached state, therefore, the fastening parts 71.1 and 71.2 of the connection coupling 60 are positively connected to the support elements 68.1, 68.2 or to the fastening legs 59.1, 59.2.

In den in den Figuren 3 und 4 gezeigten Ausführungsbeispielen weist der erfindungsgemäße U-Profil-Träger 30 an seinem Anschlussteil 45 eine zwischen den Befestigungsschenkeln 59.1 und 59.2 ausgebildete Aufnahme-Nut 65 auf, die zu dem Tragelement 46 hin nach außen offen ist und die sich in Längsrichtung 62 des U-Profil-Trägers 30 ebenfalls über die gesamte Länge des U-Profil-Trägers durchgehend erstreckt. Diese Aufnahme-Nut 65 kann zur Aufnahme eines Befestigungsmittel-Teils eines mit dem Tragelement 46 verbundenen Befestigungsmittels dienen, das hier mit einer Schraube 67 mit Schraubenkopf 66 gestaltet ist. Demgemäß kann der über die Außenoberfläche des hier rohrförmigen Tragelements 46 vorstehende Schraubenkopf 66 in der Aufnahme-Nut 65 aufgenommen werden, so dass der U-Profil-Träger 30 auch oberhalb von derart über das Tragelement 46 vorstehenden Teilen bestimmungsgemäß aufgesattelt und sicher befestigt werden kann.In the in the Figures 3 and 4 In the exemplary embodiments shown, the U-profile carrier 30 according to the invention has, at its connecting part 45, a receiving groove 65 formed between the fastening legs 59.1 and 59.2, which is open towards the carrying element 46 and which extends in the longitudinal direction 62 of the U-profile. Carrier 30 also extends continuously over the entire length of the U-profile beam. This receiving groove 65 can serve to receive a fastener part of a fastener connected to the support member 46, which is designed here with a screw 67 with screw head 66. Accordingly, the over the outer surface of the here tubular support member 46th protruding screw head 66 are received in the receiving groove 65, so that the U-profile support 30 can also be saddled and secured above above the support member 46 above projecting parts.

In den in den Figuren 3 und 4 gezeigten Ausführungsbeispielen sind die Befestigungsschenkel 59.1 und 59.2 des Auflageelements 40 des U-Profil-Trägers 30 zu den hier mit einem Kreisaußendurchmesser gebildeten rohrförmigen Tragelements 46 hin mit einer entsprechend kreiszylindrischen Anlagefläche gestaltet, deren Radius 64.1, 64.2 dem Außenradius des rohrförmigen Tragelements 46 entspricht. Auf diese Weise erhält man eine spannungsoptimierte formschlüssige Anlage des Auflageelements 40 des U-Profil-Trägers 30 an dem Tragelement 46. Es versteht sich jedoch, dass abhängig von der Außengeometrie des jeweiligen Tragelements, die diesem zugeordneten Auflageflächen des Auflageelements auch an die jeweilige Außenkontur dieser Tragelemente angepasst gestaltet sein kann, also beispielsweise mit einer ebenen, im Querschnitt geraden Fläche abgeschrägt ausgebildet sein kann. Demgemäß kann der erfindungsgemäße U-Profil-Träger 30 auf jede Art von Tragelementen, insbesondere auf jede Art von Gerüstrohren oder Gitterträgern, insbesondere mit Kreisquerschnitt, montiert werden, so dass sich ein besonders breites Einsatzspektrum dieses U-Profil-Trägers 30 ergibt.In the in the Figures 3 and 4 In the embodiments shown, the fastening legs 59.1 and 59.2 of the support element 40 of the U-profile support 30 are designed to form the tubular support element 46 formed here with a circular outer diameter with a correspondingly circular contact surface whose radius 64.1, 64.2 corresponds to the outer radius of the tubular support element 46. It is understood, however, that depending on the outer geometry of the respective support element, the associated bearing surfaces of the support element also to the respective outer contour of this support Supporting elements can be designed adapted, so for example, can be formed bevelled with a flat, straight in cross-section surface. Accordingly, the U-profile support 30 according to the invention can be mounted on any type of support elements, in particular on any type of scaffold tubes or lattice girders, in particular with a circular cross section, so that a particularly wide range of uses of this U-profile support 30 results.

Das Einsatzspektrum des U-Profil-Trägers 30 ist weiter dadurch erweitert, dass in dessen U-Profil 35 bzw. auf den Auflagerändern 39.1, 39.2 der Stützschenkel 38.1, 38.2 auch Lauf- und/oder Arbeitsflächenelemente, insbesondere Gerüstböden und vorzugsweise Einhängehilfsmittel 57 wie Einhängehaken oder Klauen derartiger Lauf- und/oder Arbeitsflächenelemente 58 eingehängt werden können, die dann mithilfe des Schnell-Spann-Elements 75 an dem U-Profil-Träger 30 festgelegt werden können oder unter Festlegung einer Abhebesicherung 56 an dem U-Profil-Träger 30 gesichert werden können. Demgemäß kann der U-Profil-Träger 30 beispielsweise auch zur Montage von Flächengerüsten aus systemfreien Gitterträgern und/oder Gerüstteilen eingesetzt werden.The range of use of the U-profile support 30 is further extended by the fact that in the U-profile 35 and on the Auflagerändern 39.1, 39.2 of the support legs 38.1, 38.2 also running and / or worktop elements, especially scaffold floors and preferably Eingehiegilfsmittel 57 as hooks or claws of such running and / or working surface elements 58 can be hung, which can then be fixed by means of the quick-tensioning element 75 on the U-profile support 30 or secured by fixing a lift-off 56 on the U-profile support 30 can be. Accordingly, the U-profile support 30 can be used, for example, for the assembly of surface structures of system-free lattice girders and / or scaffolding parts.

Die Figur 4 zeigt ein derartiges Ausführungsbeispiel des erfindungsgemäßen U-Profil-Trägers 30 eines Tragwerkes, insbesondere eines Gerüsts oder Podiums oder einer Tribüne oder Treppe, der an einem rohrförmigen Tragelement 46 mittels einer Anschlusskupplung 60 befestigt ist und an dessen U-Stütz-Schenkel 38.1, 38.2 Einhängehilfsmittel 57 bildende Einhängehaken 84 von Lauf- und/oder Arbeitsflächenelemente 58 bildenden Gerüstböden 83 mit Hilfe einem als Abhebesicherung 56 gestalteten Haltelement 77 gesichert sind, die mit Hilfe eines Schnell-Spann-Elements 75 mit Keil 80 festgelegt ist. Gleiche Elemente sind mit gleichen Bezugszeichen wie in Figur 3 versehen.The FIG. 4 shows such an embodiment of the inventive U-profile support 30 of a supporting structure, in particular a scaffold or podium or a grandstand or stairs, which is attached to a tubular support member 46 by means of a connection coupling 60 and to the U-support leg 38.1, 38.2 Einhängehilfsmittel 57 forming hooks 84 of running and / or working surface elements 58 forming scaffolding floors 83 are secured by means of a designed as a lift-off 56 support member 77 which is fixed by means of a quick-tensioning element 75 with wedge 80. The same elements are denoted by the same reference numerals as in FIG FIG. 3 Mistake.

Im Unterschied zu dem in Figur 3 gezeigten Ausführungsbeispiel ist bei dem in Figur 4 gezeigten Ausführungsbeispiel eine Sicherungsöffnung 79.2 vorgesehen, die gegenüber der Sicherungsöffnung 79.1 um etwa 90 Grad gedreht in der Sicherungslasche 76.2 angeordnet ist. Dadurch bedingt ist auch der Keil 80 um etwa 90 Grad versetzt angeordnet, so dass sich dieser nunmehr etwa parallel zu Längsrichtung 62 des U-Profil-Trägers 30 erstreckt. Dadurch können die im Gerüstbau üblichen Keile 80 platzsparend und unter Sicherheitsaspekten gut sichtbar angeordnet werden. Abgesehen von den vorstehend bezeichneten Unterschieden ist das in Figur 4 gezeigte Befestigungsmittel gleich gestaltet wie das Befestigungsmittel 55 gemäß Figur 3. Ebenfalls jeweils gleich gestaltet sind in den Figuren 3 und 4 der U-Profil-Träger 30 und die Anschlusskupplung 60. Es versteht sich jedoch, dass diese Elemente im Rahmen der Erfindung auch unterschiedlich gestaltet sein können.Unlike the in FIG. 3 embodiment shown is in the in FIG. 4 shown embodiment, a securing opening 79.2 is provided, which is arranged opposite the securing opening 79.1 rotated by about 90 degrees in the securing tab 76.2. As a result, the wedge 80 is arranged offset by about 90 degrees, so that this now extends approximately parallel to the longitudinal direction 62 of the U-profile support 30. As a result, the wedges 80 customary in scaffolding can be arranged in a space-saving and easily visible manner for safety reasons. Apart from the differences indicated above are those in FIG. 4 shown fasteners same design as the fastener 55 according to FIG. 3 , Also each designed the same in the Figures 3 and 4 the U-profile support 30 and the connection coupling 60. It is understood, however, that these elements can also be designed differently in the context of the invention.

Es versteht sich außerdem, dass der Leichtmetall-Strangpress-U-Profil-Träger 30 ohne Weiteres auf ein vor Ort gewünschtes Maß gekürzt werden kann und dann ohne irgendwelche Einschränkungen weiterverwendet werden kann.It will also be understood that the light metal extruded U-profile beam 30 can be easily shortened to a degree desired on-site and then reused without any restrictions.
