Die vorliegende Erfindung betrifft ein Gerüst, ein Vertikalrahmen für ein Gerüst sowie einen Gerüstboden für ein Gerüst und ein Verfahren zu dessen Herstellung.The present invention relates to a scaffold, a vertical frame for a scaffold and a scaffold floor for a scaffold and a method for its production.
Aus dem Stand der Technik sind verschiedene Arten von Gerüsten bekannt. Insbesondere modulare Gerüste für Fassaden, welche in einer modularen Bauweise aufgestellt werden können. Solche Gerüste bestehen im Wesentlichen aus Vertikalrahmen, die ineinander gesteckt werden und Gerüstböden, die zwischen Vertikalrahmen platziert werden. Zur Stabilisierung solcher Gerüste sind vielerorts auch Querverbindungen zwischen Vertikalrahmen vorgesehen, die als Geländer dienen. Die im Stand der Technik bekannten Einzelteile derartiger Gerüste weisen ein hohes Gewicht auf und sind aufwendig zu fertigen.Various types of scaffolds are known in the art. In particular, modular scaffolding for facades, which can be set up in a modular design. Such scaffolding consists essentially of vertical frames that are inserted into each other and scaffold floors that are placed between vertical frames. In order to stabilize such scaffoldings, cross-connections between vertical frames are also provided in many places, which serve as railings. The known in the prior art items of such scaffolds have a high weight and are expensive to manufacture.
Es ist deshalb eine Aufgabe der Erfindung, die Nachteile des Standes der Technik zu überwinden. Insbesondere soll ein Gerüst und ein Vertikalrahmen für ein Gerüst und ein Gerüstboden für ein Gerüst und ein Verfahren zu dessen Herstellung bereitgestellt werden, welche ein geringes Gewicht aufweisen und einfach zu fertigen sind.It is therefore an object of the invention to overcome the disadvantages of the prior art. In particular, a framework and a vertical frame for a scaffold and a scaffold floor for a scaffold and a method for its production are to be provided, which have a low weight and are easy to manufacture.
Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen definierten Vorrichtungen gelöst. Weitere Ausführungsformen ergeben sich aus den abhängigen Patentansprüchen.This object is achieved by the devices defined in the independent claims. Further embodiments emerge from the dependent claims.
Ein erster Aspekt der Erfindung betrifft einen Vertikalrahmen für ein Gerüst. Ein derartiger Vertikalrahmen umfasst mindestens zwei und bevorzugt genau zwei Vertikalstreben. Er umfasst des Weiteren mindestens eine, bevorzugt zwei und besonders bevorzugt genau eine Horizontalstrebe. Bei erfindungsgemässem Gebrauch des Vertikalrahmens sind die zwei Vertikalstreben in ihrem oberen Bereich durch eine obere Horizontalstrebe verbunden. Zwischen der oberen Horizontalstrebe und der Vertikalstrebe ist wenigstens eine Diagonalstrebe vorgesehen. Die Diagonalstrebe ist jeweils mit einem ihrer Enden an der Horizontalstrebe respektive an der Vertikalstrebe festgelegt. Die Diagonalstrebe ist aus einem Hohlprofil gefertigt, wobei das Hohlprofil einen Querschnitt mit unterschiedlichen axialen Aussenabmessungen aufweist. Der Querschnitt hat zumindest zwei Aussenabmessungen. Die zweite Aussenabmessung des Querschnitts der Diagonalstrebe ist kleiner als eine erste Aussenabmessung der Diagonalstrebe. Die Diagonalstrebe ist derart an der Horizontalstrebe und an der Vertikalstrebe festgelegt, dass die längere erste Aussenabmessung im Wesentlichen rechtwinklig zu einer zwischen der Horizontalstrebe und der Vertikalstrebe aufgespannten Ebene angeordnet ist.A first aspect of the invention relates to a vertical frame for a scaffold. Such a vertical frame comprises at least two and preferably exactly two vertical struts. It further comprises at least one, preferably two and more preferably exactly one horizontal strut. In the inventive use of the vertical frame, the two vertical struts are connected in their upper region by an upper horizontal strut. Between the upper horizontal strut and the vertical strut at least one diagonal strut is provided. The diagonal strut is fixed in each case with one of its ends on the horizontal strut respectively on the vertical strut. The diagonal strut is made of a hollow profile, wherein the hollow profile has a cross section with different axial external dimensions. The cross section has at least two outer dimensions. The second outer dimension of the cross section of the diagonal strut is smaller than a first outer dimension of the diagonal strut. The diagonal strut is fixed to the horizontal strut and the vertical strut such that the longer first outer dimension is substantially perpendicular to a plane defined between the horizontal strut and the vertical strut.
Ein Hohlprofil weist hohe Torsions- und Biegesteifigkeit auf. Durch das Festlegen der Diagonalstrebe zwischen Horizontal- und Vertikalstrebe wird die strukturelle Festigkeit des Vertikalrahmens erhöht. Eine Ausrichtung der längeren Aussenabmessung rechtwinklig zur Ebene vergrössert ausserdem die lichte Weite des Vertikalrahmens. Die Herstellung wird ebenfalls erleichtert.A hollow profile has high torsional and bending stiffness. By setting the diagonal brace between the horizontal and vertical braces, the structural strength of the vertical frame is increased. An alignment of the longer outer dimension perpendicular to the plane also increases the clear width of the vertical frame. The production is also facilitated.
Bevorzugt entspricht die erste Aussenabmessung des Querschnitts der Diagonalstrebe im Wesentlichen einer der Aussenabmessungen der Querschnitte der Horizontalstrebe oder der Vertikalstrebe.Preferably, the first outer dimension of the cross section of the diagonal strut corresponds substantially to one of the outer dimensions of the cross sections of the horizontal strut or the vertical strut.
Sind beispielsweise Horizontalstrebe und Vertikalstrebe ungleichen Querschnittes oder haben unterschiedliche Aussenabmessungen, so kann die Aussenabmessung der Diagonalstrebe einer der beiden Aussenabmessungen der Horizontalstrebe oder der Vertikalstrebe entsprechen. Es ist insbesondere auch möglich, dass die Horizontalstrebe als auch Vertikalstrebe Querschnitte aufweisen, welche mit einer Wandstärke ausgestattet sind. Die Aussenabmessung der Diagonalstrebe kann in der Folge der Aussenabmessung beispielsweise der Horizontal- oder Vertikalstrebe minus der jeweiligen Wandstärken entsprechen. Es ist jedoch auch möglich, dass die Aussenabmessung der Diagonalstrebe der Aussenabmessung der Horizontal- oder Vertikalstrebe zuzüglich der Wandstärken der Diagonalstrebe entspricht.For example, if horizontal strut and vertical strut unequal cross section or have different outer dimensions, the outer dimension of the diagonal strut can correspond to one of the two outer dimensions of the horizontal strut or the vertical strut. In particular, it is also possible that the Horizontal strut and vertical strut have cross-sections, which are equipped with a wall thickness. The outer dimension of the diagonal strut may correspond, for example, to the horizontal or vertical strut minus the respective wall thicknesses as a result of the outside dimension. However, it is also possible that the outer dimension of the diagonal strut corresponds to the outer dimension of the horizontal or vertical strut plus the wall thicknesses of the diagonal strut.
Wenn die Aussenabmessungen entsprechend ausgeführt sind, ergeben sich günstige Verhältnisse sowohl für den Verlauf der Kraft als auch für die Fertigung. Unterschiede der Dimensionen in der Höhe von einzelnen Wandstärken können während der Fertigung beispielsweise mit der Schweissnaht überbrückt und aneinander angeglichen werden.If the external dimensions are carried out accordingly, favorable conditions result both for the course of the force and for the production. Differences in the dimensions of the height of individual wall thicknesses can be bridged during manufacture, for example, with the weld and aligned with each other.
Bevorzugt weist die Diagonalstrebe einen rechteckigen Querschnitt auf.Preferably, the diagonal strut has a rectangular cross-section.
Es ist jedoch auch vorstellbar, dass die Diagonalstrebe einen Querschnitt aufweist, der einen polygonalen Umriss hat. So sind beispielsweise fünf oder sechs Ecken vorstellbar. Eine ovale Konfiguration ist ebenfalls vorstellbar.However, it is also conceivable that the diagonal strut has a cross section which has a polygonal outline. For example, five or six corners are conceivable. An oval configuration is also conceivable.
Derartige Querschnitte ermöglichen den Einsatz handelsüblicher Rohre oder handelsüblichem Halbzeug.Such cross sections allow the use of commercially available tubes or commercially available semi-finished products.
Bevorzugt ist die Vertikalstrebe und/oder die Horizontalstrebe ebenfalls aus einem Hohlprofil gefertigt. Bevorzugt kann das Hohlprofil ein Rundrohr sein. Vierkantrohre und Querschnitte wie oben beschrieben sind ebenfalls möglich.Preferably, the vertical strut and / or the horizontal strut is also made of a hollow profile. Preferably, the hollow profile may be a round tube. Square tubes and cross sections as described above are also possible.
Hohlprofile begünstigen die Gewichtsoptimierung solcher Vertikalrahmen. Ausserdem können sie als Stangenware gekauft werden, wobei die Anmessungen innerhalb einer engen Fertigungstoleranz liegen. Diese erlaubt eine hohe Reproduzierbarkeit sowie genaue Aussagen über die Festigkeit derartiger Vertikalrahmen. Durch Hohlprofile lässt sich ein Vertikalrahmen auch insbesondere derart gestalten, dass einzelne Vertikalrahmen unter geringem Aufwand steckbar ausgestaltet werden können.Hollow profiles favor the weight optimization of such vertical frame. In addition, they can be purchased as rod products, the measurements are within a tight manufacturing tolerance. This allows a high reproducibility and accurate statements about the strength of such vertical frame. By hollow profiles, a vertical frame can also be designed in particular such that individual vertical frame can be designed pluggable with little effort.
Ein weiterer Aspekt der Erfindung betrifft einen Vertikalrahmen, insbesondere ein Vertikalrahmen wie vorliegend beschrieben. Bevorzugt ist der Vertikalrahmen derart gestaltet, dass die Horizontalstrebe eine geringere Wandstärke aufweist als die Vertikalstrebe.Another aspect of the invention relates to a vertical frame, in particular a vertical frame as described herein. Preferably, the vertical frame is designed such that the horizontal strut has a smaller wall thickness than the vertical strut.
Eine geringere Wandstärke der Horizontalstrebe begünstigt die Gewichtsbilanz positiv. Der Vertikalrahmen kann bezüglich der Parameter Gewicht und Festigkeit in einem gewünschten Bereich optimiert werden.A smaller wall thickness of the horizontal strut favored the weight balance positive. The vertical frame can be optimized in terms of weight and strength in a desired range.
Bevorzugt ist die Vertikalstrebe und/oder die Horizontalstrebe aus einem Hohlprofil und besonders bevorzugt aus einem Rundrohr gefertigt. Andere Querschnitte, wie vorliegend beschrieben, sind ebenfalls vorstellbar, wobei die Vorteile wie vorliegend beschrieben bereits erwähnt sind.Preferably, the vertical strut and / or the horizontal strut is made of a hollow profile and particularly preferably made of a round tube. Other cross-sections, as described herein, are also conceivable, the advantages as already described hereinbefore being mentioned.
Die Vertikalstrebe ist bevorzugt aus einem Material mit einer Streckgrenze Re, besonders bevorzugt mit einer oberen Streckgrenze ReH von mindestens 320 MPa gefertigt.The vertical strut is preferably made of a material having a yield strength Re, more preferably having an upper yield strength ReH of at least 320 MPa.
Zusätzlich oder alternativ kann die Horizontalstrebe eine Streckgrenze Re von mindestens 460 MPa und/oder die Diagonalstrebe eine Streckgrenze Re von mindestens 320 MPa aufweisen. Vertikalrahmen, die aus Materialen mit höherer Streckgrenze gefertigt sind, können aus leichteren Elementen gefertigt werden. Dünnere Wandstärken sind vorstellbar.Additionally or alternatively, the horizontal strut may have a yield strength Re of at least 460 MPa and / or the diagonal strut may have a yield strength Re of at least 320 MPa. Vertical frames made from materials with higher yield strength can be made from lighter weight elements. Thinner wall thicknesses are conceivable.
In einer bevorzugten Ausführungsform ist die Horizontalstrebe aus S460MC gefertigt.In a preferred embodiment, the horizontal strut is made of S460MC.
S460MC weist gemäss Norm eine Streckgrenze Re von mindestens 460 MPa auf. Dies ist von besonderem Vorteil, da Profile und insbesondere Hohlprofile und Rundrohre bereits als Halbzeug aus diesem Material erhältlich sind.S460MC has a yield strength Re of at least 460 MPa according to the standard. This is of particular advantage, since profiles and in particular hollow profiles and round tubes are already available as a semi-finished product from this material.
Horizontalstreben aus diesem Material ermöglichen es, dünnere Profile als im Stand der Technik zu verwenden.Horizontal struts made of this material make it possible to use thinner profiles than in the prior art.
Bevorzugt weist die Horizontalstrebe eine Wandstärke kleiner oder gleich 2,7mm auf. In einer besonders bevorzugten Ausführungsform ist die Wandstärke kleiner oder gleich 2mm.The horizontal strut preferably has a wall thickness of less than or equal to 2.7 mm. In a particularly preferred embodiment, the wall thickness is less than or equal to 2mm.
Höherfeste Stähle mit geringeren Wandstärken begünstigen das Gewichtsbudget, wobei die Festigkeit immer noch gegeben ist.Higher strength steels with lower wall thicknesses favor the weight budget while still providing strength.
Zur Fertigung des Vertikalrahmens sind insbesondere alle Verbindungen der einzelnen Streben als Schweissverbindungen ausgeführt.For the manufacture of the vertical frame in particular all connections of the individual struts are designed as welded joints.
Somit lassen sich Vertikalrahmen in einem einzelnen Prozessschritt vollständig fertigen, was einen positiven Einfluss auf die Prozesssicherheit hat. Schweissverbindungen sind besonders haltbar und ermöglichen einen Vollanschluss der einzelnen Elemente untereinander.Thus, vertical frames can be completely finished in a single process step, which has a positive influence on the process reliability. Weld connections are particularly durable and allow a full connection of the individual elements with each other.
Ein weiterer Aspekt betrifft einen Gerüstboden für ein Gerüst. Ein derartiger Gerüstboden umfasst mindestens einen Längsträger und eine Bodenplatte. Verbindungselemente zum verbinden mit einem Vertikalrahmen sind ebenso vorgesehen. Die Bodenplatte ist aus einem Leichtmetall und der Längsträger aus einem dazu unterschiedlichem Metall, insbesondere aus Stahl, gefertigt.Another aspect relates to a scaffold floor for a scaffold. Such a scaffold floor comprises at least one longitudinal member and a bottom plate. Connecting elements for connection to a vertical frame are also provided. The bottom plate is made of a light metal and the side member made of a different metal, especially steel.
Eine Kombination unterschiedlicher Metalle ermöglicht eine Optimierung im Sinne von Gewicht und Festigkeit. Für strukturell stark beanspruchte Bauteile, wie die Längsträger, wird bevorzugt Stahl verwendet, da dieser eine höhere Festigkeit als beispielsweise ein Leichtmetall aufweist. Bevorzugt ist das Leichtmetall, aus dem die Bodenplatte gefertigt ist, Aluminium. Es sind jedoch auch Aluminiumlegierungen oder weitere Leichtmetalle vorstellbar.A combination of different metals allows optimization in terms of weight and strength. For structurally highly stressed components, such as the side members, steel is preferably used, since this has a higher strength than, for example, a light metal. Preferably, the light metal from which the bottom plate is made, aluminum. However, aluminum alloys or other light metals are also conceivable.
Leichtmetalle sind Metalle, welche im Wesentlichen eine Dichte geringer als 5g/cm^3 aufweisen, bevorzugte Werkstoffe sind beispielsweise Aluminium, Magnesium, Titan sowie deren Legierungen, wobei die Legierungsbestandteile nicht auf Leichtmetalle begrenzt sind.Light metals are metals which have a density substantially less than 5 g / cm 3, preferred materials are, for example, aluminum, magnesium, titanium and their alloys, the alloy constituents being not limited to light metals.
Bevorzugt sind der Längsträger und die Bodenplatte durch Durchsetzfügen aneinander festgelegt.Preferably, the side member and the bottom plate are fixed to each other by clinching.
Durchsetzfügen, auch Clinchen genannt, ermöglicht das Verbinden von Materialen unterschiedlicher Art. Je nach den zu fügenden Bauteilen, respektive den Materialeigenschaften der zu fügenden Bauteile, kann für das Durchsetzfügen ein Stempel oder eine Matrize mit darauf abgestimmten Querschnitten aufweisen. So sind beispielsweise runde oder auch eckige Querschnitte für den Stempel und die Matrize vorstellbar. Ein weiterer Vorteil des Durchsetzfügens ist ausserdem, dass Strukturen entstehen, welche die Rutschsicherheit erhöhen können.Punching, also referred to as clinching, makes it possible to join materials of different types. Depending on the components to be joined or the material properties of the components to be joined, a punch or a die with matched cross-sections can be used for the clinching. For example, round or square cross sections for the punch and the die are conceivable. Another advantage of push-through joining is also that create structures that can increase the slip resistance.
Es ist jedoch auch vorstellbar, die Längsträger mit der Bodenplatte zu verschweissen, zu verkleben oder mit Nieten zu verbinden. Das Durchsetzfügen wie auch das Fügen mit Nieten weist eine verbesserte Dauerfestigkeit auf, da derartige Fügungen weniger anfällig auf Kerbwirkung sind. Sind die einzelnen Teile mit einer Schweissung miteinander verbunden, so können weitere Schritte, beziehungsweise ein Wechsel der Fügetechnik entfallen. Sind die unterschiedlichen Teile miteinander verklebt, so wird die Belastung auf die Einzelteile im Fertigungsprozess zusätzlich vermindert, da weder eine Materialumwandlung noch eine Bearbeitung oder ein Entfernen von Material nötig ist.However, it is also conceivable to weld the side members to the bottom plate, to glue or to connect with rivets. The clinching as well as the rivet joining has an improved fatigue strength because such joints are less prone to notching. If the individual parts are connected to one another by welding, further steps or a change in the joining technique can be dispensed with. If the different parts are glued together, the burden on the individual parts in the manufacturing process is further reduced, since neither a material conversion nor a processing or removal of material is necessary.
Es ist ausserdem vorstellbar, vorgenannte Fügeverfahren zu kombinieren. Insbesondere die Kombination aus Durchsetzfügeverbindung mit einer Klebeverbindung oder eine Nietverbindung mit einer Klebeverbindung ist vorteilhaft.It is also conceivable to combine the aforementioned joining methods. In particular, the combination of clinching with an adhesive bond or a riveted joint with an adhesive bond is advantageous.
In einer bevorzugten Ausführungsform weist der Gerüstboden einen zweiten Längsträger auf, wobei die Längsträger beidseitig der Bodenplatte festgelegt sind.In a preferred embodiment, the scaffold floor on a second side member, wherein the side members are fixed on both sides of the bottom plate.
Gerüstböden weisen typischerweise eine längliche Erstreckung auf. Wenn Längsträger beidseitig an einem Gerüstbrett festgelegt sind, so sind sie im Wesentlichen beidseitig an einer Längsachse angeordnet, wobei die Längsträger sowohl stirnseitig an der Bodenplatte befestigt sein können, sich aber auch zumindest teilweise quer zur Längsachse unter oder über die Bodenplatte im erfindungsgemässen Gebrauch erstrecken können.Scaffolding floors typically have an elongated extent. If longitudinal members are fixed on both sides to a scaffold board, they are arranged substantially on both sides on a longitudinal axis, wherein the longitudinal beams may be both frontally attached to the bottom plate, but also at least partially transverse to the longitudinal axis under or over the bottom plate in the inventive use ,
Der Gerüstboden kann somit symmetrisch zur Längsachse aufgebaut sein.The scaffold floor can thus be constructed symmetrically to the longitudinal axis.
Zwischen beidseitig der Bodenplatte festgelegten Längsträgern können weitere Längsträger vorgesehen sein um je nach Länge der Bodenplatte respektive des Gerüstbodens zur zusätzlichen Festigkeit des Gerüstbodens beizutragen. Die Längsträger verleihen dem Gerüstboden insbesondere auch eine räumliche Struktur, wobei räumliche Strukturen insbesondere höhere Biegemomente aufnehmen können und in der Folge bezüglich der Festigkeit vorteilhaft sind.Between both sides of the bottom plate fixed side members further longitudinal members may be provided to contribute depending on the length of the bottom plate and the scaffold floor for additional strength of the scaffolding floor. In particular, the longitudinal members also impart a spatial structure to the scaffold floor, wherein spatial structures can accommodate in particular higher bending moments and are consequently advantageous in terms of strength.
Bevorzugt sind die beidseitig der Bodenplatte vorgesehenen Längsträger aus Stahl gefertigt. Es ist aber auch vorstellbar, dass sämtliche Längsträger aus Stahl gefertigt sind. Weiter bevorzugt sind sämtliche Längsträger durch Durchsetzfügen an der Bodenplatte festgelegt.Preferably, the longitudinal members provided on both sides of the bottom plate are made of steel. But it is also conceivable that all side members are made of steel. More preferably, all the longitudinal members are fixed by clinching on the bottom plate.
Der Gerüstboden kann ein Stirnprofil aufweisen. Stirnprofile ermöglichen die Aufnahme der Verbindungselemente. Insbesondere kann ein Formschluss zwischen den Verbindungselementen und dem Stirnprofil vorgesehen sein. Formschlüssige Verbindungen begünstigen den Kraftverlauf.The scaffold floor may have a frontal profile. Face profiles allow the inclusion of the fasteners. In particular, a positive connection between the connecting elements and the end profile can be provided. Positive connections favor the force curve.
Ein weiterer Aspekt betrifft einen Gerüstboden, der zumindest einen Längsträger, eine Bodenplatte, ein Stirnprofil sowie Verbindungselemente zum Verbinden mit einem bevorzugt wie vorliegend beschriebenen Vertikalrahmen umfasst. Das Stirnprofil ist aus einem Leichtmetall gefertigt. Der Längsträger oder die Bodenblatte ist aus einem dazu unterschiedlichen Material und bevorzugt aus Stahl gefertigt. Es ist auch vorstellbar, dass sowohl die Bodenplatte als auch der Längsträger aus demselben, zum Material des Stirnprofils unterschiedlichem Material gefertigt sind.Another aspect relates to a scaffold floor comprising at least one longitudinal beam, a bottom plate, a frontal profile and connecting elements for connection to a preferably described as vertical frame. The front profile is made of a light metal. The longitudinal beam or the bottom blade is made of a different material and preferably made of steel. It is also conceivable that both the bottom plate and the longitudinal beam from the same, for Material of the front profile of different material are made.
Das Stirnprofil ist bevorzugt aus Aluminium oder einer seiner Legierungen gefertigt. Die Vorteile solcher Leichtmetalle sind vorliegend erwähnt.The end profile is preferably made of aluminum or one of its alloys. The advantages of such light metals are mentioned here.
Da Stirnprofile hohe Kräfte und Momente aufnehmen müssen, werden bevorzugt Profile mit grossen Materialstärken und/oder Querschnitten verwendet. Durch den Einsatz eines Leichtmetalles kann Gewicht eingespart werden.Since face profiles must absorb high forces and moments, profiles with large material thicknesses and / or cross-sections are preferably used. By using a light metal weight can be saved.
Das Stirnprofil kann zumindest mit den beidseitig der Bodenplatte festgelegten Längsträgern verbunden und bevorzugt verschweisst sein. Bevorzugt ist es mit sämtlichen Längsträgern verbunden und insbesondere verschweisst.The end profile can be at least connected to the side members of the bottom plate fixed side members and preferably welded. It is preferably connected to all longitudinal members and in particular welded.
Derartige Schweissungen können mit speziellen Verfahren hergestellt werden, die dem Fachmann bekannt sind.Such welds can be made by special methods known to those skilled in the art.
Bevorzugt sind die Verbindungselemente mit dem Stirnprofil verbunden. Es kann ein Formschluss vorgesehen sein. In einer bevorzugten Ausführungsform sind die Verbindungselemente mit dem Stirnprofil verschweisst. Es ist jedoch auch vorstellbar, die Stirnprofile einstückig auszuführen, wobei die Verbindungselemente bereits in den Stirnprofilen integriert sind.Preferably, the connecting elements are connected to the end profile. It may be provided a positive connection. In a preferred embodiment, the connecting elements are welded to the end profile. However, it is also conceivable to carry out the end profiles in one piece, wherein the connecting elements are already integrated in the end profiles.
Mit dem Stirnprofil verschweisste Verbindungselemente ermöglichen die freie Platzierung der Verbindungselemente während der Fertigung.Fasteners welded to the face profile allow for free placement of fasteners during manufacturing.
Die Verbindungselemente können aus einem Leichtmetall und insbesondere aus Aluminium oder einer seiner Legierungen gefertigt sein.The connecting elements may be made of a light metal and in particular of aluminum or one of its alloys.
In einer bevorzugten Ausführungsform kann die Bodenplatte eine Struktur zur Erhöhung der Stabilität aufweisen. Durch Sicken oder Abkantungen wird das Trägheitsmoment der Bodenplatte und/oder des ganzen Gerüstbodens erhöht. Ausserdem haben Sicken oder Abkantungen einen positiven Einfluss auf die Erhöhung der Steifigkeit. Insbesondere erhabene Sicken können auch zur Erhöhung der Rutschsicherheit beitragen.In a preferred embodiment, the bottom plate may have a structure for increasing the stability. By beading or bending the moment of inertia of the bottom plate and / or the whole scaffolding floor is increased. In addition, beads or bends have a positive influence on increasing the rigidity. In particular, raised beads can also contribute to increasing the slip resistance.
Zur Erhöhung der Rutschsicherheit kann auch vorgesehen sein, die Bodenplatte mit einem zusätzlichen Belag beispielsweise aus Gummi oder Quarzsand zu versehen.To increase the slip resistance may also be provided to provide the bottom plate with an additional covering, for example, rubber or quartz sand.
Die Längsprofile können ebenfalls eine Struktur zur Erhöhung der Stabilität und insbesondere Sicken oder Abkantungen aufweisen. Wie vorliegend beschrieben kann durch derartige Strukturen das Trägheitsmoment und die Steifigkeit positiv beeinflusst werden.The longitudinal profiles may also have a structure for increasing the stability and in particular beads or bends. As described herein, inertial momentum and stiffness can be positively influenced by such structures.
Bevorzugt weisen die Längsprofile, insbesondere die beidseitig der Bodenplatte festgelegten Längsprofile, eine Formgebung zur Schaffung eines ergonomischen Profils auf, welche das Tragen des Gerüstbodens erleichtert. Bevorzugt weisen die Längsprofile in ihrem Querschnitt eine Verjüngung auf.The longitudinal profiles, in particular the longitudinal profiles defined on both sides of the floor panel, preferably have a shape for creating an ergonomic profile, which facilitates the carrying of the framework floor. The longitudinal profiles preferably have a taper in their cross section.
Die Verjüngung kann als Eindellung ausgebildet sein, welche bevorzugt quer zur Längsrichtung oder zur Längsachse ausgebildet ist. Im erfindungsgemässen Gebrauch des Gerüstbodens weist die Eindellung eine aus Sicht der Längsachse konvexe Form auf.The taper may be formed as a dent, which is preferably formed transversely to the longitudinal direction or the longitudinal axis. In the inventive use of the scaffold floor, the indentation has a convex shape from the perspective of the longitudinal axis.
Der Arbeiter oder Monteur kann zum Tragen des Gerüstes nun in eine Art Hinterschnitt eingreifen. Ein derartiger Hinterschnitt macht das Tragen eines Gerüstbodens komfortabler und sicherer.The worker or fitter can now intervene in a kind of undercut to support the framework. Such an undercut makes carrying a scaffolding floor more comfortable and safer.
Bevorzugt ist der Hinterschnitt derart gestaltet, dass keine eckigen Kanten entstehen, sondern der Teil des Querschnittes der Längsträger, welche zum Tragen oder zum Greifen des Gerüstbodens vorgesehen sind, mit Radien versehen sind. Bevorzugt weist der Längsträger einen abgerundeten Hinterschnitt auf, der sich gegenüber einem virtuellen rechteckigen Querschnitt des Längsträgers mit einem Winkel zwischen 10° und 60°, bevorzugt zwischen 20° und 45° und besonders bevorzugt zwischen 25° und 35° erstreckt.Preferably, the undercut is designed such that no angular edges arise, but the part of the cross section of the longitudinal members, which are provided for carrying or for gripping the scaffold floor, are provided with radii. Preferably, the longitudinal member has a rounded undercut, which extends with respect to a virtual rectangular cross section of the longitudinal member at an angle between 10 ° and 60 °, preferably between 20 ° and 45 ° and particularly preferably between 25 ° and 35 °.
Ein weiterer Aspekt der vorliegenden Erfindung betrifft ein Gerüst, insbesondere ein Fassadengerüst. Das Gerüst umfasst mindestens einen wie vorliegend beschriebenen Vertikalrahmen. Das Gerüst wird somit insgesamt leichter. Dies bedeutet eine Entlastung für die Arbeiter / Gerüstbauer. Ebenfalls ist es möglich, Transportfahrzeuge mit mehr Elementen zu beladen, da das Gesamtgewicht des Transporters erst mit einer höheren Stückzahl von einzelnen Elementen erreicht wird.Another aspect of the present invention relates to a scaffold, in particular a facade scaffold. The framework comprises at least one vertical frame as described herein. The framework thus becomes lighter overall. This means a relief for the workers / scaffolders. It is also possible to load transport vehicles with more elements, since the total weight of the van is achieved only with a higher number of individual elements.
Ein weiterer Aspekt betrifft ein Verfahren zum Herstellen eines Gerüstbodens, insbesondere eines Gerüstbodens, der zumindest einen Längsträger und eine Bodenplatte umfasst. Die Bodenplatte wird mit dem Längsträger durch Durchsetzfügen miteinander verbunden.A further aspect relates to a method for producing a scaffold floor, in particular a scaffold floor, which comprises at least one longitudinal member and a base plate. The bottom plate is connected to the side member by clinching.
Eine Herstellung von Gerüstböden, welche unterschiedliche Materialen umfassen, wird dadurch ermöglicht oder erleichtert. Bevorzugt wird mit einem weiteren Schritt zusätzlich ein Stirnprofil mit den Längsträgern verschweisst. Dies ermöglicht eine höhere Festigkeit in hoch beanspruchten Teilen. Ausserdem ist ein Vollanschluss der Längsträger an die Stirnprofile möglich.A production of scaffold floors comprising different materials is thereby made possible or facilitated. Preferably, with a further step, an end profile is additionally welded to the longitudinal members. This allows higher strength in highly stressed parts. In addition, a full connection of the side members to the front profiles is possible.
