Definitions
- the invention relates to a heavy-duty bolt, a scaffold, a method for producing a heavy-duty bolt and a method for producing a scaffold according to the preamble of the independent claims.
- a disadvantage of the known scaffold part is that it consists of an extruded profile, which is provided with a profile for reinforcement.
- a scaffold bolt which consists of two sub-profiles, the lower profile having cutouts for the vertical passage of scaffold elements.
- a disadvantage of the known scaffold latch is that the two sub-profiles have to be connected to one another by welding and so the production is labor intensive and correspondingly expensive.
- a scaffold element which consists of two partial profiles.
- one of the partial profiles is designed as a round profile.
- one of the partial profiles is designed as a U-profile.
- a disadvantage of this scaffold element is that two sub-profiles have to be connected to one another during the manufacture of the element.
- the object is achieved by a heavy-duty bolt, a method for producing a heavy-duty bolt and a method for producing a scaffold according to the independent claims.
- a heavy-duty bolt for use on a scaffold comprises an upper profile, a middle profile and a lower profile.

- the heavy-duty bolt is designed according to the invention in such a way that the upper profile, the middle profile and the lower profile are formed in one piece.
- the heavy-duty bar can thus be manufactured in a single piece.
- the design of the upper profile makes it easy to attach the fastening device for connecting the heavy-duty bolt to other scaffolding parts, thus further simplifying the manufacture of the heavy-duty bolt (including the connecting device).
- One-piece means that the three profiles of the heavy-duty bolt are made from a single material in one piece and that several separate pieces are not joined together to form a heavy-duty bolt by means of a connection technology.
- the upper profile, the middle profile and the lower profile differ from one another in shape, orientation and / or thickness of the material, at least insofar as the profiles are directly adjacent to one another.
- the fastening elements are designed as recesses on the upper profile.
- the fastening elements can be designed such that a fastening device, for example a wedge head, can simply be attached in the heavy-duty bolt.
- a fastening device can be inserted into the profile and fixed using the fastening elements.
- the fasteners can therefore include holes.
- the fastening element in the upper profile can be designed such that a fastening device can be clicked into the fastening elements without tools. This eliminates the need to tighten screws or other fasteners. This further simplifies the manufacture of the heavy-duty bar.
- the upper profile of the heavy-duty bolt is designed as a round profile.
- a round profile enables particularly advantageous strength and even force distribution.
- a round profile also enables a fastening device to be inserted easily, the round profile at least partially surrounding the fastening device at the same time and thus protecting it from bad weather conditions.
- a lower profile of the heavy-duty bolt is designed as a U-profile or a round profile.
- a U-profile has high strength and buckling resistance. This enables the heavy-duty bolt to be made with less heavy materials, especially with light metal.

- the same heavy-duty bolt can be used for different scaffolding constructions.
- the cutouts are designed as a substantially rectangular cutout. Recesses in other Embodiments such as oval or polygonal cutouts are also conceivable.
- the heavy-duty bolt has at least one recess of a first type with a first length in the direction of the longitudinal axis.
- the heavy-duty bolt also has a recess of a second type with a second length in the direction of the longitudinal axis. The first and second lengths differ in size.
- the longitudinal axis runs along the length of the heavy-duty transom.
- the heavy-duty bolt comprises a plurality, in particular four or three, of recesses of a first type and a plurality, in particular five or four or three or two, recesses of a second type.
- the first type of recess is longer in the direction of the longitudinal axis than the second Type of cutout.
- Such heavy-duty bars allow a large variety in the construction of scaffolding.
- the center profile has a wall thickness of 1 mm to 6 mm, preferably 2-5 mm, particularly preferably a wall thickness of 3 mm.
- the wall thicknesses of the upper profile and the lower profile prefer in the range of 2-7mm, especially 3-5mm.
- the upper profile comprises a wedge head for fastening the heavy-duty bolt to a perforated disc of a vertical handle.
- a wedge head is a head which is designed to receive a wedge and a perforated disk, the perforated disk being able to be guided into the wedge head and the wedge head being insertable in a form-fitting manner by introducing the wedge into a hole in the perforated disk.
- Such wedge heads are well known from the prior art.
- the heavy-duty latch has holes in the upper profile for fastening the wedge head.
- the wedge head can be easily connected to the upper profile.
- the wedge head and the holes are designed such that the wedge head can be clicked into the holes. This enables a particularly simple connection of the wedge head to the upper profile, without the need for tools.
- the lower profile or the central profile and the lower profile are at least partially trapezoidal in longitudinal section.

- the heavy-duty bar is formed from aluminum or an aluminum alloy, in particular an aluminum extrusion process.
- the heavy-duty bars can thus be moved without great effort, in particular raised.
- the lightweight construction of the heavy-duty bolts enables the bolt to be handled by just one person. This simplifies the use of the heavy-duty bolt.
- the central profile has only one contact with the upper and / or lower profile in cross section.
- the heavy-duty bolt is particularly simple and stable, that is to say it is reinforced by the central profile and the profile below.
- the length of the lower profile in cross section is 50% to 150% of the length of the lower profile.
- the length of the lower profile is preferably 75% to 125%, particularly preferably 70% to 110% of the length of the central profile.
- the length of the upper profile is 40% to 140% of the length of the lower profile.
- a scaffold also leads to the solution of the task.
- the scaffold comprises at least one heavy-duty bar as described above and below.
- the scaffold further comprises at least a first vertical post and a second vertical post.
- the heavy-duty bar is attached vertically to the two vertical posts.
- scaffolding elements run vertically through the cutouts in the heavy-duty bolt.
- the strength of the scaffold can be reinforced by additional elements that are guided through the recesses in the heavy-duty bar.
- a scaffold with a heavy-duty bolt with recesses allows a variety of different scaffold designs without having to rely on another heavy-duty bolt.
- the object is also achieved by a method for producing a heavy-duty bar.
- the heavy duty bar as described above is made by extrusion.
- Extrusion allows the heavy-duty bar to be made from one piece. The time-consuming manual connection of individual profile parts is eliminated. The manufacture of the heavy-duty bar can be carried out particularly economically.
- the method for producing the heavy-duty bolt comprises a further step in which recesses are excluded.
- recesses are excluded from the central profile.
- the recesses are preferably milled. However, cutting or eroding would also be conceivable.
- the heavy-duty bolt in a first step, can be made in one piece, i.e. in one piece. Then, in a second step, this can be provided with cutouts by mechanical processing, so that despite the one-piece production, it is possible to carry out scaffolding elements through the heavy-duty latch. In this way, simple and economical production can be used without having to forego the flexibility in the scaffolding construction, which is made possible by the cutouts.
- a method for producing a scaffold also leads to the solution of the task.
- a heavy-duty bar is mounted between two vertical posts as described above and below.
- the result is a scaffold, as described above, in which the advantageous heavy-duty bolt is installed and which, because of its particularly high strength, enables a wide range of scaffold construction options with a relatively light construction.
- the method for producing the scaffolding comprises in a further step the insertion of a scaffolding element running perpendicular to the heavy-duty bolt into a recess in the heavy-duty bolt.
- the scaffolding can be reinforced with additional elements.

Description
Die Erfindung betrifft einen Schwerlastriegel, ein Gerüst, ein Verfahren zur Herstellung eines Schwerlastriegels sowie ein Verfahren zur Herstellung eines Gerüsts gemäss dem Oberbegriff der unabhängigen Ansprüche.The invention relates to a heavy-duty bolt, a scaffold, a method for producing a heavy-duty bolt and a method for producing a scaffold according to the preamble of the independent claims.
Es ist bei Schwerlastriegel bekannt, dass diese aufgrund der hohen Festigkeitsanforderungen vorwiegend aus Stahl in Form von mehreren Teilprofilen hergestellt und anschliessend beispielsweise durch Schweissen miteinander verbunden werden. Dieser Aufbau aus mehreren Teilprofilen ist insbesondere in der Herstellung nachteilig, da die einzelnen Teile aufwendig miteinander verbunden werden müssen. Weiter werden solche Schwerlastriegel aufgrund der Festigkeitsanforderungen meistens aus Stahl hergestellt und sind deshalb verhältnismässig schwer.It is known in the case of heavy-duty bolts that, due to the high strength requirements, they are predominantly made of steel in the form of several partial profiles and are then connected to one another, for example by welding. This construction from several partial profiles is disadvantageous in particular in the production, since the individual parts have to be connected to one another in a complex manner. Furthermore, such heavy-duty bars are mostly made of steel due to the strength requirements and are therefore relatively heavy.
Aus der
Nachteilig bei dem bekannten Gerüstteil ist, dass dieses aus einem Stangpressprofil besteht, welches zur Verstärkung mit einem Profil versehen wird.A disadvantage of the known scaffold part is that it consists of an extruded profile, which is provided with a profile for reinforcement.
Aus der
Nachteilig bei dem bekannten Gerüstriegel ist, dass die beiden Teilprofile durch Schweissen miteinander verbunden werden müssen und so die Herstellung arbeitsintensiv und entsprechend teuer ist.A disadvantage of the known scaffold latch is that the two sub-profiles have to be connected to one another by welding and so the production is labor intensive and correspondingly expensive.
Aus der
Nachteilig bei diesem Gerüstelement ist wiederum, dass bei der Herstellung des Elements zwei Teilprofile miteinander verbunden werden müssen.A disadvantage of this scaffold element is that two sub-profiles have to be connected to one another during the manufacture of the element.
Es ist die Aufgabe der vorliegenden Erfindung einen Schwerlastriegel zu schaffen, welcher die Nachtteile des Standes der Technik vermeidet und insbesondere einen Schwerlastriegel, ein Gerüst, ein Verfahren zur Herstellung eines Schwerlastriegels sowie ein Verfahren zur Herstellung eines Gerüstes zu schaffen, bei welchen der Schwerlastriegel besonders einfach herstellbar, leicht und dennoch fest ausgebildet ist.It is the object of the present invention to provide a heavy-duty bolt which avoids the night parts of the prior art and in particular to provide a heavy-duty bolt, a scaffold, a method for producing a heavy-duty bolt and a method for producing a scaffold in which the heavy-duty bolt is particularly simple producible, light and yet solid.
Die Aufgabe wird durch einen Schwerlastriegel, ein Verfahren zur Herstellung eines Schwerlastriegels sowie ein Verfahren zur Herstellung eines Gerüsts gemäss den unabhängigen Ansprüchen gelöst.The object is achieved by a heavy-duty bolt, a method for producing a heavy-duty bolt and a method for producing a scaffold according to the independent claims.
Erfindungsgemäss umfasst ein Schwerlastriegel zur Verwendung an einem Gerüst ein oberes Profil, ein Mittenprofil und ein unteres Profil. Das obere Profil ist derart ausgebildet, dass Befestigungsmittel zur Befestigung des Schwerlastriegels am oberen Profil befestigbar sind. Der Schwerlastriegel ist erfindungsgemäss so ausgebildet, dass das obere Profil, das Mittenprofil und das untere Profil einstückig ausgebildet sind.According to the invention, a heavy-duty bolt for use on a scaffold comprises an upper profile, a middle profile and a lower profile. The upper profile is designed in such a way that fastening means for fastening the heavy-duty bolt can be fastened to the upper profile. The heavy-duty bolt is designed according to the invention in such a way that the upper profile, the middle profile and the lower profile are formed in one piece.
Vorteilhaft erweist sich, dass so der Herstellung des Schwerlastriegels vereinfacht wird, da das Verbinden von verschiedenen Teilprofilen entfällt. Der Schwerlastriegel kann so in einem einzigen Stück hergestellt werden. Durch die Ausgestaltung des oberen Profils kann ein einfaches Anbringen der Befestigungsvorrichtung zur Verbindung des Schwerlastriegels mit anderen Gerüstteilen sichergestellt werden und so die Herstellung des Schwerlastriegels (inklusive Verbindungsvorrichtung) weiter vereinfacht werden.It proves advantageous that the manufacture of the heavy-duty bolt is simplified in this way, since there is no need to connect different partial profiles. The heavy-duty bar can thus be manufactured in a single piece. The design of the upper profile makes it easy to attach the fastening device for connecting the heavy-duty bolt to other scaffolding parts, thus further simplifying the manufacture of the heavy-duty bolt (including the connecting device).
Mit einstückig ist gemeint, dass die drei Profile des Schwerlastriegels aus einem einzigen Material in einem Stück hergestellt sind und nicht mehrere separate Stücke durch eine Verbindungstechnik zu einem Schwerlastriegel zusammengefügt werden.One-piece means that the three profiles of the heavy-duty bolt are made from a single material in one piece and that several separate pieces are not joined together to form a heavy-duty bolt by means of a connection technology.
Das obere Profil, das Mittenprofil und das untere Profil unterscheiden sich voneinander in Form, Ausrichtung und/oder dicke des Materials, zumindest soweit es sich um direkt aneinander angrenzende Profile handelt.The upper profile, the middle profile and the lower profile differ from one another in shape, orientation and / or thickness of the material, at least insofar as the profiles are directly adjacent to one another.
Die Befestigungselemente sind in einer Ausführungsform als Aussparungen am oberen Profil ausgeführt. Die Befestigungselemente können so ausgeführt sein, dass eine Befestigungsvorrichtung, beispielsweise eine Keilkopf einfach im Schwerlastriegel anbringbar ist. Für den Fall eines hohlen Profils kann eine Befestigungsvorrichtung in das Profil eingeführt und über die Befestigungselemente fixiert werden. Die Befestigungselemente können daher Löcher umfassen. Beispielsweise kann das Befestigungselement im oberen Profil so ausgeführt sein, dass eine Befestigungsvorrichtung ohne Werkzeug in die Befestigungselemente eingeklickt werden kann. So entfällt das Anziehen von Schrauben oder anderen Befestigungsmitteln. Die Herstellung des Schwerlastriegels wird dadurch weiter vereinfacht.In one embodiment, the fastening elements are designed as recesses on the upper profile. The fastening elements can be designed such that a fastening device, for example a wedge head, can simply be attached in the heavy-duty bolt. In the case of a hollow profile, a fastening device can be inserted into the profile and fixed using the fastening elements. The fasteners can therefore include holes. For example, the fastening element in the upper profile can be designed such that a fastening device can be clicked into the fastening elements without tools. This eliminates the need to tighten screws or other fasteners. This further simplifies the manufacture of the heavy-duty bar.
In einer bevorzugten Ausführungsform ist das obere Profil des Schwerlastriegels als Rundprofil ausgebildet.In a preferred embodiment, the upper profile of the heavy-duty bolt is designed as a round profile.
Vorteilhaft erweist sich, dass ein Rundprofil eine besonders vorteilhafte Festigkeit und gleichmässige Kraftverteilung ermöglicht. Ein Rundprofil ermöglicht weiter ein einfaches Einsetzen einer Befestigungsvorrichtung, wobei das Rundprofil die Befestigungsvorrichtung zu gleich wenigstens teilweise umgibt und somit diese von schlechten Witterungsbedingungen schützt.It has been shown to be advantageous that a round profile enables particularly advantageous strength and even force distribution. A round profile also enables a fastening device to be inserted easily, the round profile at least partially surrounding the fastening device at the same time and thus protecting it from bad weather conditions.
In einer bevorzugten Ausführungsform ist ein unteres Profil des Schwerlastriegels als U-Profil oder Rundprofil ausgebildet.In a preferred embodiment, a lower profile of the heavy-duty bolt is designed as a U-profile or a round profile.
Vorteilhaft erweist sich, dass ein U-Profil eine hohe Festigkeit und Knicksteifigkeit aufweist. Dies ermöglicht es den Schwerlastriegel mit weniger schweren Materialien, insbesondere mit Leichtmetall herzustellen.It proves to be advantageous that a U-profile has high strength and buckling resistance. This enables the heavy-duty bolt to be made with less heavy materials, especially with light metal.
In einer bevorzugten Ausführungsform weist das Mittenprofil des Schwerlastriegels wenigstens eine Aussparung zur Durchführung von Gerüstelementen auf.In a preferred embodiment, the center profile of the heavy-duty bolt has at least one recess for the passage of scaffolding elements.
So kann der Schwerlastriegel in einem Gerüst verbaut werden, wobei auch zum Schwerlastriegel senkrecht verlaufende Querelemente im Gerüst verbaut werden können. Ein solcher Schwerlastriegel ist auf Grund der Aussparung besonders universell einsetzbar und zum Aufbau von verschiedenen Gerüsten geeignet. Es kann derselbe Schwerlastriegel für verschiedene Gerüstkonstruktionen verwendet werden.For example, the heavy-duty bolt can be installed in a scaffold, and transverse elements that run perpendicular to the heavy-duty bolt can also be installed in the scaffold. Such a heavy-duty bolt can be used universally due to the recess and is suitable for the construction of various scaffolding. The same heavy-duty bolt can be used for different scaffolding constructions.
Die Aussparungen sind in einer Ausführungsform als im Wesentlichen rechteckige Aussparung ausgeführt. Aussparungen in anderer Ausführungsform wie beispielsweise oval oder N-eckig Aussparungen sind ebenfalls denkbar.In one embodiment, the cutouts are designed as a substantially rectangular cutout. Recesses in other Embodiments such as oval or polygonal cutouts are also conceivable.
In einer bevorzugten Ausführungsform weist der Schwerlastriegel wenigstens eine Aussparung einer ersten Art mit einer in Richtung der Längsachse ersten Länge auf. Der Schwerlastriegel weist ebenfalls eine Aussparung einer zweiten Art mit einer in Richtung der Längsachse zweiten Länge auf. Die erste und die zweite Länge unterscheiden sich in ihrer Grösse.In a preferred embodiment, the heavy-duty bolt has at least one recess of a first type with a first length in the direction of the longitudinal axis. The heavy-duty bolt also has a recess of a second type with a second length in the direction of the longitudinal axis. The first and second lengths differ in size.
Die Langsachse läuft entlang der Länge des Schwerlastriegels.The longitudinal axis runs along the length of the heavy-duty transom.
Dies erlaubt eine noch flexiblere Ausgestaltung eines Gerüstes mit diesem erfindungsgemässen Schwerlastriegel. Insbesondere können so Querelemente von verschiedenen Grössen verwendet werden.This allows an even more flexible design of a scaffold with this heavy-duty bolt according to the invention. In particular, cross elements of different sizes can be used in this way.
In einer Ausführungsform umfasst der Schwerlastriegel eine Vielzahl, insbesondere vier oder drei, Aussparungen einer ersten Art und eine Vielzahl, insbesondere fünf oder vier oder drei oder zwei, Aussparungen einer zweiten Art. Die erste Art Aussparung ist in Richtung der Längsachse länger ausgebildet als die zweite Art der Aussparung.In one embodiment, the heavy-duty bolt comprises a plurality, in particular four or three, of recesses of a first type and a plurality, in particular five or four or three or two, recesses of a second type. The first type of recess is longer in the direction of the longitudinal axis than the second Type of cutout.
Solche Schwerlastriegel erlauben eine grosse Vielfallt im Aufbau von Gerüsten.Such heavy-duty bars allow a large variety in the construction of scaffolding.
In einer Ausführungsform weist das Mittenprofil eine Wandstärke von 1 mm bis 6 mm, bevorzugt von 2-5 mm besonders bevorzugt eine Wandstärke von 3 mm auf. Die Wanddicken des oberen Profils und des unteren Profils lieben bevorzugt im Bereich von 2-7mm, insbesondere 3-5mm.In one embodiment, the center profile has a wall thickness of 1 mm to 6 mm, preferably 2-5 mm, particularly preferably a wall thickness of 3 mm. The wall thicknesses of the upper profile and the lower profile prefer in the range of 2-7mm, especially 3-5mm.
Solche Wandstärken erlauben es Schwerlastriegel herzustellen, die eine ausreichende Festigkeit aufweisen.Such wall thicknesses allow heavy-duty bars to be produced that have sufficient strength.
In einer bevorzugten Ausführungsform umfasst das obere Profil einen Keilkopf zur Befestigung des Schwerlastriegels an einer Lochscheibe eines Vertikalstiels.In a preferred embodiment, the upper profile comprises a wedge head for fastening the heavy-duty bolt to a perforated disc of a vertical handle.
Ein Keilkopf ist ein Kopf, welcher zur Aufnahme eines Keils und einer Lochscheibe ausgestaltet ist, wobei die Lochscheibe in den Keilkopf führbar ist und der Keilkopf durch Einbringen des Keils in ein Loch der Lochscheibe formschlüssig einführbar ist. Solche Keilköpfe sind aus dem Stand der Technik bestens bekannt.A wedge head is a head which is designed to receive a wedge and a perforated disk, the perforated disk being able to be guided into the wedge head and the wedge head being insertable in a form-fitting manner by introducing the wedge into a hole in the perforated disk. Such wedge heads are well known from the prior art.
In einer Ausführungsform umfasst der Schwerlastriegel im oberen Profil Löcher zur Befestigung des Keilkopfs.In one embodiment, the heavy-duty latch has holes in the upper profile for fastening the wedge head.
Vorteilhaft erweist sich, dass so der Keilkopf einfach mit dem oberen Profil verbunden werden kann. In einer Ausführungsform sind der Keilkopf und die Löcher so ausgeführt, dass der Keilkopf in die Löcher eingeklickt werden kann. Dies ermöglicht eine besonders einfache Verbindung des Keilkopfs mit dem oberen Profil, ohne dass dazu Werkzeuge benötig werden.It proves advantageous that the wedge head can be easily connected to the upper profile. In one embodiment, the wedge head and the holes are designed such that the wedge head can be clicked into the holes. This enables a particularly simple connection of the wedge head to the upper profile, without the need for tools.
In einer bevorzugten Ausführungsform sind das untere Profil oder das Mittenprofil und das untere Profil im Längsschnitt wenigstens teilweise trapezförmig ausgebildet.In a preferred embodiment, the lower profile or the central profile and the lower profile are at least partially trapezoidal in longitudinal section.
So entsteht ein Schwerlastriegel, der auf Grund des Mittenprofils und des unteren Profils stabil ist und dennoch einfach zwischen Vertikalstielen angebracht werden kann, da die Trapezform ein einfaches Einführen des Schwerlastriegels zwischen die Vertikalstiele ermöglicht.This creates a heavy-duty latch, which is stable due to the central profile and the lower profile, but can still be easily attached between vertical handles, since the trapezoidal shape enables the heavy-duty latch to be easily inserted between the vertical handles.
Bevorzugt sind das obere und das untere Profil Rund - oder U-Profile. Das Mittenprofil ist bevorzugt ein Steg. Diese Angaben gelten für den Querschnitt.The upper and lower profiles are preferably round or U profiles. The central profile is preferably a web. This information applies to the cross-section.
In einer bevorzugten Ausführungsform ist der Schwerlastriegel aus Leichtmetall gebildet. In einer besonders bevorzugten Ausführungsform ist der Schwerlastriegel aus Aluminium oder einer Aluminiumlegierung, insbesondere einer Aluminium-Strangpressverfahren gebildet.In a preferred embodiment, the heavy-duty bolt is made of light metal. In a particularly preferred embodiment, the heavy-duty bar is formed from aluminum or an aluminum alloy, in particular an aluminum extrusion process.
So entstehen Schwerlastriegel, welche besonders leicht und deshalb besonders einfach handhabbar sind. Die Schwerlastriegel können so ohne grosse Anstrengung bewegt, insbesondere in die Höhe gehoben werden. Der Leichtbau der Schwerlastriegel ermöglicht die Handhabung des Riegels durch nur eine Person. So wird die Verwendung des Schwerlastriegels vereinfacht.This creates heavy-duty bars that are particularly light and therefore particularly easy to handle. The heavy-duty bars can thus be moved without great effort, in particular raised. The lightweight construction of the heavy-duty bolts enables the bolt to be handled by just one person. This simplifies the use of the heavy-duty bolt.
In einer bevorzugten Ausführungsform weisst das Mittenprofil im Querschnitt nur einen Kontakt zum oberen und/oder unteren Profil auf.In a preferred embodiment, the central profile has only one contact with the upper and / or lower profile in cross section.
Vorteilhaft erweist sich, dass so der Schwerlastriegel besonders einfach und stabil, das heisst durch das Mittenprofil und das unter Profil verstärkt ausgebildet ist.It proves to be advantageous that the heavy-duty bolt is particularly simple and stable, that is to say it is reinforced by the central profile and the profile below.
In einer Ausführungsform ist im Querschnitt die Länge des unteren Profils 50 % bis 150 % der Länge des unteren Profils. Bevorzugt ist im Querschnitt die Länge des unteren Profils 75 % bis 125 %, besonders bevorzugt 70 % bis 110 % der Länge des Mittenprofils.In one embodiment, the length of the lower profile in cross section is 50% to 150% of the length of the lower profile. In cross section, the length of the lower profile is preferably 75% to 125%, particularly preferably 70% to 110% of the length of the central profile.
In einer Ausführungsform ist im Querschnitt die Länge des oberen Profils 40 % bis 140 % der Länge des unteren Profils. Bevorzugt ist im Querschnitt die Länge des oberen Profils 60 % bis 120 %, besonders bevorzugt 70 % bis 110 % der Länge des unteren Profils.In one embodiment, in cross-section, the length of the upper profile is 40% to 140% of the length of the lower profile. Prefers in cross section the length of the upper profile is 60% to 120%, particularly preferably 70% to 110% of the length of the lower profile.
Somit erhält man ein optimales Verhältnis von Kraftverteilung und Gewicht.This gives you an optimal ratio of force distribution to weight.
Zur Lösung der Aufgabe führt ebenfalls ein Gerüst. Das Gerüst umfasst wenigstens einen Schwerlastriegel wie vorangehende und im Folgenden beschrieben. Das Gerüst umfasst weiter zumindest einen ersten Vertikalstiel und einen zweiten Vertikalstiel. Der Schwerlastriegel ist senkrecht an den beiden Vertikalstielen befestigt.A scaffold also leads to the solution of the task. The scaffold comprises at least one heavy-duty bar as described above and below. The scaffold further comprises at least a first vertical post and a second vertical post. The heavy-duty bar is attached vertically to the two vertical posts.
Vorteilhaft erweist sich, dass ein solches Gerüst durch die hohe Festigkeit des Schwerlastriegels stabil und dennoch leicht ist, da der Schwerlastriegel aufgrund der formbedingten hohen Fettigkeit aus einem entsprechend leichten Material ausgebildet werden kann.It proves to be advantageous that such a scaffold is stable due to the high strength of the heavy-duty bolt, yet is light, since the heavy-duty bolt can be formed from a correspondingly light material due to the high fatness due to the shape.
In einer bevorzugten Ausführungsform verlaufen vertikal durch die Aussparungen des Schwerlastriegels Gerüstelemente.In a preferred embodiment, scaffolding elements run vertically through the cutouts in the heavy-duty bolt.
Die Festigkeit des Gerüstes kann durch weitere Elemente, welche durch die Aussparungen der Schwerlastriegels geführt werden verstärkt werden. Ein Gerüst mit einem Schwerlastriegel mit Aussparungen erlaubt so eine Vielzahl verschiedener Gerüstkonstruktion, ohne dabei auf einen anderen Schwerlastriegel angewiesen zu sein.The strength of the scaffold can be reinforced by additional elements that are guided through the recesses in the heavy-duty bar. A scaffold with a heavy-duty bolt with recesses allows a variety of different scaffold designs without having to rely on another heavy-duty bolt.
Die Aufgabe wird ebenfalls durch ein Verfahren zur Herstellung eines Schwerlastriegels gelöst. Der Schwerlastriegel wie vorangehend beschrieben wird durch Strangpressen hergestellt.The object is also achieved by a method for producing a heavy-duty bar. The heavy duty bar as described above is made by extrusion.
Strangpressen erlaubt die Herstellung des Schwerlastriegels aus einem Stück. Das aufwändige manuelle Verbinden von einzelnen Profilteilen entfällt. Die Herstellung des Schwerlastriegels kann so besonders ökonomisch ausgeführt werden.Extrusion allows the heavy-duty bar to be made from one piece. The time-consuming manual connection of individual profile parts is eliminated. The manufacture of the heavy-duty bar can be carried out particularly economically.
In einer bevorzugten Ausführungsform umfasst das Verfahren zur Herstellung des Schwerlastriegels einen weiteren Schritt, in welchem Aussparungen ausgenommen werden. Bei einer besonders bevorzugten Ausführungsform werden Aussparungen aus dem Mittenprofil ausgenommen. Die Aussparungen werden bevorzugt gefräst. Denkbar wäre jedoch auch schneiden oder erodieren.In a preferred embodiment, the method for producing the heavy-duty bolt comprises a further step in which recesses are excluded. In a particularly preferred embodiment, cutouts are excluded from the central profile. The recesses are preferably milled. However, cutting or eroding would also be conceivable.
Der Schwerlastriegel kann so in einem ersten Schritt aus einem Stück, das heisst einstückig hergestellt werden. Anschliessend, in einem zweiten Schritt kann dieser durch mechanische Bearbeitung mit Aussparungen versehen werden, sodass trotz der einstückigen Herstellung die Durchführung von Gerüstelementen durch den Schwerlastriegel ermöglicht wird. So kann die einfache und ökonomische Herstellung eingesetzt werden, ohne dabei auf die Flexibilität in der Gerüstkonstruktion, welche durch die Aussparungen ermöglicht werden, verzichten zu müssen.In a first step, the heavy-duty bolt can be made in one piece, i.e. in one piece. Then, in a second step, this can be provided with cutouts by mechanical processing, so that despite the one-piece production, it is possible to carry out scaffolding elements through the heavy-duty latch. In this way, simple and economical production can be used without having to forego the flexibility in the scaffolding construction, which is made possible by the cutouts.
Zur Lösung der Aufgabe führt ebenfalls ein Verfahren zur Herstellung eines Gerüsts. Beim Verfahren wird ein Schwerlastriegel wie vorangehend und im Folgenden beschrieben zwischen zwei Vertikalstielen montiert.A method for producing a scaffold also leads to the solution of the task. In the process, a heavy-duty bar is mounted between two vertical posts as described above and below.
So entsteht ein Gerüst, wie vorangehend beschrieben, in welchem der vorteilhafte Schwerlastriegel verbaut ist und welches sich daher durch eine besonders hohe Festigkeit, vielfältige Gerüstkonstruktionsmöglichkeiten bei verhältnismässig leichter Bauweise ermöglicht.The result is a scaffold, as described above, in which the advantageous heavy-duty bolt is installed and which, because of its particularly high strength, enables a wide range of scaffold construction options with a relatively light construction.
In einer bevorzugten Ausführungsform umfasst das Verfahren zur Herstellung des Gerüstes in einem weiteren Schritt das Einführen eines senkrecht zum Schwerlastriegel verlaufen Gerüstelements in eine Aussparung des Schwerlastriegels.In a preferred embodiment, the method for producing the scaffolding comprises in a further step the insertion of a scaffolding element running perpendicular to the heavy-duty bolt into a recess in the heavy-duty bolt.
So kann das Gerüst durch weitere Elemente verstärkt werden.In this way, the scaffolding can be reinforced with additional elements.

Das vierte Ausführungsbeispiel des Schwerlastriegels 1 (der vierte Schwerlastriegel 1 von oben) ist wiederum länger als der Schwerlastriegel 1 des dritten Ausführungsbeispiels. Die ungefähre Länge des Schwerlastriegels 1 ergibt sich aus der Summe der Distanzen 12 (1500 mm), 16 (500 mm), 17 (500 mm) und 18 (500 mm). Dieser Schwerlastriegel 1 umfasst dieselbe Anzahl an Aussparung 6 wie das dritte Ausführungsbeispiel, wobei die mittlere Aussparung weiter von den anderen Aussparungen beabstandet ist.The fourth exemplary embodiment of the heavy-duty bolt 1 (the fourth heavy-
Der Schwerlastriegel 1 des fünften Ausführungsbeispiels ist wiederum länger ausgebildet als der Schwerlastriegel 1 des vierten Ausführungsbeispiels. Die ungefähre Länge des Schwerlastriegels 1 ergibt sich aus der Summe der Distanzen 12 (1500 mm), 16 (500 mm), 17 (500 mm), 18 (500 mm) und 19 (500 mm). Im Vergleich zum vierten Ausführungsbeispiel weist das fünfte Ausführungsbeispiel eine weitere mittige Aussparung der zweiten Art auf. Dieses Ausführungsbeispiel weist mittig also zwei Aussparungen 6 der zweiten Art auf. Es ergibt sich so von links gesehen eine erste Aussparung 6 der zweiten Art gefolgt von einer ersten Aussparung 6 der ersten Art, einer zweiten Aussparung 6 der ersten Art einer zweiten Aussparung 6 der zweiten Art, einer dritten Aussparung 6 der zweiten Art, einer dritten Aussparung 6 der ersten Art, einer vierten Aussparung 6 der ersten Art, gefolgt von einer vierten Aussparung der zweiten Art.The heavy-
Das sechste Ausführungsbeispiel ist wiederum länger ausgebildet als das fünfte Ausführungsbeispiel, wobei sich die ungefähre Gesamtlänge des sechsten Ausführungsbeispiels aus der Summe der Distanzen 12 (1500 mm), 16 (500 mm), 17 (500 mm), 18 (500 mm), 19 (500 mm) und 20 (500 mm) ergibt. Dieses Ausführungsbeispiel weist eine weitere, dritte Aussparung der zweiten Art in der Mitte des Schwerlastriegels auf. Von der virtuellen Nulllinie zur Mitte der von links ausgesehen ersten Aussparung 6 (Aussparung der zweiten Art) ergibt sich eine Distanz 22 (500 mm). Die Distanz 23 (200 mm) ergibt sich von der Mitte von dieser von links ausgesehen ersten Aussparung 6 zu der von links ausgesehen zweiten Aussparung 6 (Aussparung der ersten Art). Zur Mitte der nächsten Aussparung (zweiten Aussparung der ersten Art von links ausgesehen) ergibt sich eine Distanz 24 (300 mm). Zur Mitte der nächsten Aussparung (zweite Aussparung der zweiten Art) ergibt sich eine Distanz 25 (500 mm). Zur Mitte der nächsten Aussparung 6 (dritte Aussparung der zweiten Art) ergibt sich eine Distanz 26 (500 mm). Zur Mitte der nächsten Aussparung 6 (vierte Aussparung der zweiten Art) ergibt sich eine Distanz 27 (500 mm). Zur Mitte der nächsten Aussparung 6 (dritte Aussparung der ersten Art) ergibt sich eine Distanz 28 (500 mm). Zur Mitte der nächsten Aussparung (vierte Aussparung der ersten Art) ergibt sich eine Distanzen 29 (300 mm). Zur Mitte der letzten Aussparung (fünfte Aussparung der zweiten Art) ergibt sich eine Distanz 30 (200 mm).The sixth embodiment is again longer than the fifth embodiment, the approximate total length of the sixth embodiment being the sum of the distances 12 (1500 mm), 16 (500 mm), 17 (500 mm), 18 (500 mm), 19 (500 mm) and 20 (500 mm) results. This exemplary embodiment has a further, third recess of the second type in the middle of the heavy-duty bolt. A distance 22 (500 mm) results from the virtual zero line to the center of the first recess 6 (recess of the second type) as seen from the left.
