- Hünnebeck's Bosta 70 vertical frame which has been on the market for a long time, uses an upwardly open U-profile with two peripheral circular holes in the bottom, which are slid onto the upper ends of the vertical posts and welded to the upper horizontal bar.
- the U-profile is laterally over the vertical posts on both sides, so that the upper corner is reinforced. Therefore, it is also possible here to dispense with a strut in the nodal region,
- the current Bosta 70 profile from Hünnebeck as a generic state of the art uses U-profiles that are open towards the side as upper horizontal struts.
- the U-profile is cut out semicircular edge in the bottom area, so that the strut is pushed from the side on the vertical post and welded.
- the fact that the opening in the bottom region of the strut forms only a semicircle, the U-profile does not completely surround the vertical post. It is therefore also a strut in the node area necessary, only with shorter Bosta 70 frame with a length smaller than 150 cm can be dispensed with this strut because of the lower bending and torsional moments.
- Bosta 70 frame has stronger vertical posts 49.4 x 3.25 ST37 / S235JRH.
- the posts of the competitors have the weaker dimension or 48.3 x 2.7 mm.
- the expert therefore assumes that when using a U-profile as the upper horizontal strut special stiffening measures are to be taken in the node area, for example, therefore comes a laterally projecting U-profile with two edge-side circular holes in the ground used or open to the side U Profiles require struts in the node area to keep the frame rectangular.
- the invention is therefore an object of the invention to provide an improved vertical frame of the generic type.
- the upper end of the vertical posts terminates almost flush with the upper edge of the upper horizontal struts, a tripping hazard is avoided during scaffolding setup or in the upper position. A substantially flush closure is when tripping is almost impossible with hinged floor.
- the upper end of the vertical post a maximum of 20 mm, preferably max, protrude 10 mm above the horizontal strut.
- the upper end of the vertical post which is designed as a connecting means, is formed only by the normal, continuous hollow profile of the vertical post, further manufacturing steps are unnecessary. In particular, it is dispensed with a separate stiffening.
- a semicircular recess is introduced into the bottom region of the upwardly open horizontal strut, such that the vertical limbs of the U-shaped profile project beyond the edge region in the axial direction.
- these protruding legs can affect the outer diameter of the vertical post. If this recess in the bottom area substantially forms a semicircle of about 180 degrees, a particularly favorable welding can take place with the vertical post, which runs along the free ends of the vertical legs of the U-profile and the semicircular opening in the bottom area. In essence, therefore, the inner diameter of the upper U-profile is as large as the outer diameter of the vertical post
- Another embodiment provides a Einsteckling at the lower end of the vertical post.
- the Einstecklinge have a smaller diameter than the vertical posts and are intended for insertion into the upper opening of an underlying, similar vertical frame. Since the slightly thinner Einsteckling is provided at the bottom of the frame, there are two advantages: In the construction of a scaffold, the Einsteckling therefore does not go beyond the floor covering so that tripping hazards are prevented. In addition, in the Einsteckling penetrating dirt is harmless to the structure, it would be annoying if the upper pipe opening with stones or dirt is added. However, this will not usually happen, as the frames are usually on a dirty ground on the Einsteckling.
- the insert is usually secured by welding, riveting or crimping inside the lower end portion of the vertical post.
- pipe material is provided as a vertical post, which has at least a diameter of 48.0 mm, preferably 48.3 mm, and / or at least a wall thickness of 2.5 mm, preferably 2.7 mm and a maximum diameter of 50.0 mm , preferably 49.4 mm and / or a maximum wall thickness of 3.50 mm, preferably 3.25 mm.
- the material is at least ST37, preferably with a yield strength REH at least 320 N / mm 2 , and / or maximum ST52, preferably ST52 / S355JRH is.
- a vertical post pipe material 48.3 x 2.7 ST52 - preferably S355JRH- or 49.4 x 3.25 ST37 - preferably S235JRH - provided.
- a vertical post profiles are provided, which are less than or the same as tube material 49.4 x 3.25 ST37 / S235JRH designed.
- the tube material is not aluminum.
- the tube material is made of steel and / or the tube material has a wall thickness of 2.5 - 2.7 mm.
- FIG. 1 shows a frame 1 according to the invention, which consists essentially of two vertical posts 2 and horizontal struts 5, 6 fastened therebetween.
- the vertical posts are in the embodiment, the above-mentioned pipe material, which has an upper pipe opening 8 in the upper end portion 4, the tube is not specially processed.
- Einstecklinge 7 are introduced into the opening of the tube material 2 and thus connected by welding / riveting or crimping.
- the lower horizontal strut 6 is a round profile and welded between the vertical posts.
- the innovation according to the invention in the region of the upper horizontal strut 5 in contrast to the lower horizontal strut, the upper horizontal strut 5 is not formed as a closed profile, but as a weaker upwardly open profile, namely U-profile.
- the upwardly directed opening 51 extends almost over the entire width of the frame, namely between the two inner sides of the vertical posts 2.
- a semicircular recess is excluded at the edge, so that the lateral cheeks 52 of the U-profile the vertical posts. 2 can wrap around half. All seams 53 between U-profile 5 and outer wall of the vertical posts 2 are welded.
- the U-profile is particularly smooth on the vertical post and is welded there with this, are also no parts over, at appropriate points, the U-profile is connected by leadership, distance and stabilizing webs 11, the one allow defined hanging the floors, not shown.

Der seit längerer Zeit auf dem Markt befindliche Bosta 70-Vertikalrahmen von Hünnebeck verwendet als obere Horizontalstrebe ein nach oben offenes U-Profil mit zwei randseitigen Kreislöchern im Boden, welche auf die oberen Enden der Vertikalpfosten aufgeschoben und verschweißt werden. Dabei steht das U-Profil beidseitig seitlich über die Vertikalpfosten über, so dass die obere Ecke verstärkt ist. Daher kann auch hier auf eine Strebe im Knotenbereich verzichtet werden,Hünnebeck's Bosta 70 vertical frame, which has been on the market for a long time, uses an upwardly open U-profile with two peripheral circular holes in the bottom, which are slid onto the upper ends of the vertical posts and welded to the upper horizontal bar. The U-profile is laterally over the vertical posts on both sides, so that the upper corner is reinforced. Therefore, it is also possible here to dispense with a strut in the nodal region,
Das aktuelle Bosta 70-Profil von Hünnebeck als gattungsbildender Stand der Technik verwendet dagegen zur Seite hin offene U-Profile als obere Horizontalstrebe. Das U-Profil ist dabei randseitig im Bodenbereich halbkreisförmig ausgeschnitten, so dass die Strebe von der Seite her auf den Vertikalpfosten aufgeschoben und verschweißt wird. Dadurch, dass die Öffnung im Bodenbereich der Strebe nur einen Halbkreis bildet, umschließt das U-Profil den Vertikalpfosten nicht vollständig. Es ist daher ebenfalls eine Strebe im Knotenbereich nötig, Lediglich bei kürzeren Bosta 70-Rahmen mit einer Länge kleiner als 150 cm kann wegen der geringeren Biege- und Torsionsmomente auf diese Strebe verzichtet werden.By contrast, the current Bosta 70 profile from Hünnebeck as a generic state of the art uses U-profiles that are open towards the side as upper horizontal struts. The U-profile is cut out semicircular edge in the bottom area, so that the strut is pushed from the side on the vertical post and welded. The fact that the opening in the bottom region of the strut forms only a semicircle, the U-profile does not completely surround the vertical post. It is therefore also a strut in the node area necessary, only with shorter Bosta 70 frame with a length smaller than 150 cm can be dispensed with this strut because of the lower bending and torsional moments.
Der oben genannte Bosta 70 Rahmen weist stärkere Vertikalpfosten 49,4 x 3,25 ST37/S235JRH auf. Die Pfosten der Wettbewerber haben das schwächere Maß oder 48,3 x 2,7 mm. Der Fachmann geht daher davon aus, dass beim Einsatz eines U-Profils als oberer Horizontalstrebe besondere aussteifende Maßnahmen im Knotenbereich zu treffen sind, beispielsweise kommt daher ein seitlich überstehendes U-Profil mit zwei randseitigen Kreislöchern im Boden zum Einsatz oder bei zur Seite hin geöffneten U-Profilen sind Streben im Knotenbereich erforderlich, damit der Rahmen rechteckig bleibt.The above-mentioned Bosta 70 frame has stronger vertical posts 49.4 x 3.25 ST37 / S235JRH. The posts of the competitors have the weaker dimension or 48.3 x 2.7 mm. The expert therefore assumes that when using a U-profile as the upper horizontal strut special stiffening measures are to be taken in the node area, for example, therefore comes a laterally projecting U-profile with two edge-side circular holes in the ground used or open to the side U Profiles require struts in the node area to keep the frame rectangular.
Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Vertikalrahmen der gattungsgemäßen Art zu schaffen.The invention is therefore an object of the invention to provide an improved vertical frame of the generic type.
Diese Aufgabe wird durch einen Vertikalrahmen mit den Merkmalen des Hauptanspruchs gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a vertical frame having the features of the main claim. Advantageous embodiments of the invention are Subject of the dependent claims.
Erfindungsgemäß sind die gattungsbildenden Vertikalrahmen dadurch gekennzeichnet, dass im Knotenbereich keinerlei Aussteifungen zwischen Horizontalstreben und Vertikalpfosten vorgesehen sind, Beim Stand der Technik war bei vergleichbaren Vertikalrahmen immer eine besondere Aussteifung des Knotenbereichs notwendig, beispielsweise durch eine Verstrebung, umschließende Bauweise der oberen Horizontalstrebe zur Erhöhung des Kontaktes oder das obere Rohrende des Vertikalpfostens aussteifende Einstecklinge. Alternativ nahm man an, dass die Wahl von geschlossenen Horizontalprofilen nötig sei, wenn auf andere Aussteifungen verzichtet wird.According to the generic frame vertical frame are characterized in that no stiffening between horizontal struts and vertical posts are provided in the node area, In the prior art was always comparable stiffening of the node area necessary for comparable vertical frame, for example, by a strut enclosing construction of the upper horizontal strut to increase the contact or the upper tube end of the vertical post stiffening Einstecklinge. Alternatively, it was assumed that the choice of closed horizontal profiles would be necessary if other stiffeners were omitted.
Wenn dabei das obere Ende der Vertikalpfosten nahezu bündig mit der Oberkante der oberen Horizontalstreben abschließt, wird beim Gerüstaufbau oder in der oberen Lage eine Stolperfalle vermieden. Ein im Wesentlichen bündiges Abschließen liegt dann vor, wenn ein Stolpern bei eingehängtem Boden nahezu ausgeschlossen ist. Dazu kann das obere Ende des Vertikalpfostens maximal 20 mm, vorzugsweise max, 10 mm über die Horizontalstrebe ragen.If the upper end of the vertical posts terminates almost flush with the upper edge of the upper horizontal struts, a tripping hazard is avoided during scaffolding setup or in the upper position. A substantially flush closure is when tripping is almost impossible with hinged floor. For this purpose, the upper end of the vertical post a maximum of 20 mm, preferably max, protrude 10 mm above the horizontal strut.
Die Ausführung der oberen Horizontalstrebe als nach oben offenes Profil, beispielsweise V- oder U-Profil hat den Vorteil, dass Laufböden, insbesondere sich zu zwei Richtungen erstreckende Laufböden, besonders leicht und sicher eingehängt werden können. Allerdings war die Fachwelt immer davon ausgegangen, dass die oben beschriebene Konstruktion des Knotenbereichs einen nicht hinreichend torsions- und biegesteifen Rahmen ergibt, wenn auf Aussteifungselemente verzichtet wird. Überraschenderweise wurde dies in Versuchen festgestellt.The execution of the upper horizontal strut as an open-topped profile, such as V or U-profile has the advantage that running floors, especially running to two directions running floors, can be hung particularly easily and safely. However, experts have always assumed that the above-described construction of the nodal region does not provide a sufficiently torsional and rigid frame when bracing elements are dispensed with. Surprisingly, this was found in experiments.
Wenn die randseitigen Enden der Horizontalstrebe im Knotenbereich die Vertikalpfosten nicht seitlich überragen, ergeben sich zahlreiche Vorteile. Durch die glatte, kantenlose Bauweise reduziert sich das Verletzungsrisiko. Es wird eine größere Durchgangsbreite und eine bessere Kopffreiheit erreicht. Es wird weniger Material verbaut und die Herstellung des Rahmens erfordert weniger Bearbeitungsaufwand und Fertigungsschritte.If the marginal ends of the horizontal strut in the node area do not project laterally beyond the vertical posts, there are numerous advantages. The smooth, edgeless design reduces the risk of injury. It is achieved a larger passage width and better headroom. It is installed less material and the Manufacturing the frame requires less processing and manufacturing steps.
Wenn das obere Ende der Vertikalpfosten, welches als Verbindungsmittel ausgebildet ist, lediglich durch das normale, durchgehende Hohlprofil des Vertikalpfostens gebildet wird, erübrigen sich weitere Fertigungsschritte. Insbesondere wird dabei auf eine separate Aussteifung verzichtet.If the upper end of the vertical post, which is designed as a connecting means, is formed only by the normal, continuous hollow profile of the vertical post, further manufacturing steps are unnecessary. In particular, it is dispensed with a separate stiffening.
Randseitig wird in den Bodenbereich der nach oben offenen Horizontalstrebe eine halbkreisförmige Ausnehmung eingebracht, derart, dass die senkrechten Schenkel des U-förmigen Profils den Bodenbereich randseitig in axialer Richtung überragen. Somit können diese überstehenden Schenkel den Außendurchmesser des Vertikalpfostens tangieren. Wenn dabei diese Ausnehmung im Bodenbereich im Wesentlichen einen Halbkreis von ca. 180 Grad bildet, kann eine besonders günstige Verschweißung mit dem Vertikalpfosten stattfinden, die entlang der freien Enden der senkrechten Schenkel des U-Profils und der halbkreisförmigen Öffnung im Bodenbereich verläuft. Im Wesentlichen ist also der Innendurchmesser des oberen U-Profils so groß wie der Außendurchmesser des VertikalpfostensOn the edge side, a semicircular recess is introduced into the bottom region of the upwardly open horizontal strut, such that the vertical limbs of the U-shaped profile project beyond the edge region in the axial direction. Thus, these protruding legs can affect the outer diameter of the vertical post. If this recess in the bottom area substantially forms a semicircle of about 180 degrees, a particularly favorable welding can take place with the vertical post, which runs along the free ends of the vertical legs of the U-profile and the semicircular opening in the bottom area. In essence, therefore, the inner diameter of the upper U-profile is as large as the outer diameter of the vertical post
Eine weitere Ausgestaltung sieht einen Einsteckling am unteren Ende der Vertikalpfosten vor. Die Einstecklinge haben einen geringeren Durchmesser als die Vertikalpfosten und sind zum Einstecken in die obere Öffnung eines darunter liegenden, gleichartigen Vertikalrahmens bestimmt. Da der etwas dünnere Einsteckling am Unterteil des Rahmens vorgesehen ist, ergeben sich zwei Vorteile: Bei dem Aufbau eines Gerüstes überragt der Einsteckling daher nicht nach oben gehend den Bodenbelag, so dass Stolperfallen verhindert werden. Außerdem ist in den Einsteckling eindringender Schmutz unschädlich für den Aufbau, Störender wäre es, wenn die obere Rohröffnung mit Steinen oder Schmutz zugesetzt wird. Dies wird aber üblicherweise nicht geschehen, da die Rahmen auf schmutzigem Untergrund in der Regel auf dem Einsteckling stehen. Wenn der Übergang zwischen Einsteckling und Vertikalpfosten einen Anschlag, also eine Stufe bildet, können übereinander liegende Vertikalrahmen definiert positioniert werden. Die unten angeordneten Einstecklinge haben den Vorteil, dass keine Einstecklinge in der obersten Lage überstehen und Stolperfalle vermieden werden.Another embodiment provides a Einsteckling at the lower end of the vertical post. The Einstecklinge have a smaller diameter than the vertical posts and are intended for insertion into the upper opening of an underlying, similar vertical frame. Since the slightly thinner Einsteckling is provided at the bottom of the frame, there are two advantages: In the construction of a scaffold, the Einsteckling therefore does not go beyond the floor covering so that tripping hazards are prevented. In addition, in the Einsteckling penetrating dirt is harmless to the structure, it would be annoying if the upper pipe opening with stones or dirt is added. However, this will not usually happen, as the frames are usually on a dirty ground on the Einsteckling. If the transition between Einsteckling and vertical post forms a stop, so a step, superimposed vertical frame can be positioned defined. The cuttings arranged below have the advantage that no Einstecklinge survive in the uppermost layer and tripping hazard can be avoided.
Der Einsteckling ist in der Regel durch Verschweißen, Vernieten oder Verquetschen im Inneren des unteren Endbereichs des Vertikalpfostens befestigt.The insert is usually secured by welding, riveting or crimping inside the lower end portion of the vertical post.
Im Gerüstbau wurden bislang Vertikalrohre 49,4 x 3,25 ST37/S235JRH bzw, 48,3 x 3,2 eingesetzt, Überraschenderweise wurde nun herausgefunden, dass sogar bei der Verwendung von insgesamt schwächer ausgelegtem Rohrmaterial 48,3 x 2,7 ST52/S355JRH auf die aussteifenden Streben verzichtet werden kann. Der Fachmann ist in der Vergangenheit irrtümlich davon ausgegangen, dass selbst bei Verwendung des stabileren Materials 49,4 x 3,25 Verstrebungen im Knotenbereich nötig sind, sogar bei dem Einsatz von Einstecklingen, um einen hinreichend steifen Rechteckrahmen mit einer Höhe von über 1,00 m mit einem seitlich offenen U-Profil zu bauen. Der Fachmann vermutet nämlich, dass das oben genannte dünnere Material mit der dünneren Wandstärke trotz der höheren Streckgrenze weniger stabil ist und würde daher keinerlei Veranlassung haben, die sogar beim dickeren Material offensichtlich notwendige Verstrebung wegzulassen.In scaffolding, vertical tubes 49.4 x 3.25 ST37 / S235JRH or 48.3 x 3.2 have been used so far. Surprisingly, it has now been found that even with the use of generally poorer designed tubing, 48.3 x 2.7 ST52 / S355JRH can be dispensed with the stiffening struts. One skilled in the art has erroneously assumed in the past that even with the use of the more stable material, 49.4 x 3.25 struts are needed in the knot area, even with the use of pegs, about a sufficiently rigid rectangular frame with a height of over 1.00 m to build with a laterally open U-profile. The person skilled in the art assumes, in fact, that the above-mentioned thinner material with the thinner wall thickness is less stable despite the higher yield strength and therefore would have no reason to omit the bracing that is obviously necessary for the thicker material.
Vorzugsweise ist als Vertikalpfosten Rohrmaterial vorgesehen, welches mindestens einen Durchmesser von 48,0 mm, vorzugsweise 48,3 mm, und/oder mindestens eine Wandstärke von 2,5 mm, vorzugsweise 2,7 mm aufweist und maximal einen Durchmesser von 50,0 mm, vorzugsweise 49,4 mm und/oder maximal eine Wandstärke von 3,50 mm, vorzugsweise 3,25 mm aufweist.Preferably, pipe material is provided as a vertical post, which has at least a diameter of 48.0 mm, preferably 48.3 mm, and / or at least a wall thickness of 2.5 mm, preferably 2.7 mm and a maximum diameter of 50.0 mm , preferably 49.4 mm and / or a maximum wall thickness of 3.50 mm, preferably 3.25 mm.

The mentioned exemplary embodiments are not exhaustive and have exemplary character.
Im Folgenden wird die erfindungsgemäße Neuerung im Bereich der oberen Horizontalstrebe 5 beschrieben; Im Gegensatz zur unteren Horizontalstrebe ist die obere Horizontalstrebe 5 nicht als geschlossenes Profil, sondern als schwächeres nach oben offenes Profil, nämlich U-Profil ausgebildet. Die nach oben gerichtete Öffnung 51 erstreckt sich nahezu über die gesamte Breite des Rahmens, nämlich zwischen den beiden Innenseiten der Vertikalpfosten 2. Im U-Profil 5 ist randseitig eine halbkreisförmige Ausnehmung ausgenommen, so dass die seitlichen Wangen 52 des U-Profils den Vertikalpfosten 2 zur Hälfte umschließen können. Sämtliche Nahtstellen 53 zwischen U-Profil 5 und Außenwandung der Vertikalpfosten 2 sind verschweißt. Durch die halbkreisförmige randseitige Ausnehmung liegt das U-Profil besonders glatt am Vertikalpfosten an und ist auch dort mit diesem verschweißt, Auch stehen keine Teile über, An geeigneten Stellen ist das U-Profil durch Führungs-, Abstands- und Stabilisierungsstege 11 verbunden, die ein definiertes Einhängen der nicht dargestellten Böden ermöglichen.In the following, the innovation according to the invention in the region of the upper
