Weiterhin ist es aus den Druckschriften DE 10 2005 012 904 A1 und DE 103 05 158 A1 bekannt, dass die Sicherheitsgeländer mit seitlich angebrachten Streben oder Stiften an den Vertikalholmen des Baugerüstes befestigt werden.Furthermore, it is from the pamphlets DE 10 2005 012 904 A1 and DE 103 05 158 A1 It is known that the safety railings are fastened to the vertical bars of the scaffolding with laterally attached struts or pins.

Nachteilhaft an den bekannten Sicherheitsgeländern ist, dass deren Handhabung kompliziert ist und dass die bisher bekannten Sicherheitsgeländer lediglich jeweils mit Baugerüsten einer bestimmten Herstellermarke kompatibel sind.A disadvantage of the known safety railings is that handling them is complicated and that the previously known safety railings are only compatible with scaffolding from a specific manufacturer brand.

Weiterhin erfüllen die bisher bekannten temporären Sicherheitsgeländer die seit Februar 2019 herrschende Sicherheitsnorm TRBS 2121 Teil 1 nicht. Diese Norm besagt unter anderem, dass als Absturzsicherung an dem temporären Sicherheitsgeländer zwei Horizontalholme ausgebildet sein müssen.Furthermore, the previously known temporary safety railings do not meet the TRBS 2121 Part 1 safety standard that has been in force since February 2019. This standard states, among other things, that two horizontal rails must be constructed on the temporary safety railing as fall protection.

Im Übrigen wird noch auf die Druckschriften EP 0 728 884 A1 , WO 2013/030805 A1 und TW M 425 905 U als allgemeiner Stand der Technik verwiesen. FR2748290A1 offenbart ein Sicherheitsgeländer mit einem Montageadapter.Incidentally, the pamphlets will still be referred to EP 0 728 884 A1 , WO 2013/030805 A1 and TW M 425 905 U referred to as general prior art. FR2748290A1 discloses a safety rail with a mounting adapter.

Es ist daher Aufgabe der Erfindung, ein vorauseilendes Sicherheitsgeländer sowie eine alternative Art der Befestigung des Sicherheitsgeländers an einem Baugerüst zu schaffen, welche die voranstehend genannten Probleme lösen. Weiterhin ist es Aufgabe der Erfindung, ein entsprechendes Baugerüst und Verfahren hierfür bereitzustellen.It is therefore the object of the invention to provide a safety railing in advance and an alternative way of fastening the safety railing to a scaffolding which solves the problems mentioned above. Furthermore, it is the object of the invention to provide a corresponding scaffolding and method for this.

Diese Aufgaben werden durch die Merkmale der unabhängigen Patentansprüche gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand untergeordneter Ansprüche.These objects are solved by the features of the independent patent claims. Advantageous developments of the invention are the subject matter of subordinate claims.

Der Erfinder hat erkannt, dass mittels eines Montageadapters, welcher einerseits an dem Baugerüst und an welchem andererseits das Sicherheitsgeländer befestigt werden kann, ein flexibel einsetzbares Sicherheitsgeländer bereitgestellt werden kann. Der Montageadapter kann dabei so ausgestaltet werden, dass das Sicherheitsgeländer mit Baugerüsten diverser Hersteller verwendet werden kann. Weiterhin ist der Auf- und Abbau eines Baugerüstes mit Hilfe von derartigen Montageadaptern, an denen das Sicherheitsgeländer temporär befestigt wird, ohne großen zusätzlichen Aufwand möglich.The inventor has recognized that a safety railing that can be used flexibly can be provided by means of a mounting adapter, which can be attached to the scaffolding on the one hand and to which the safety railing can be attached on the other hand. The mounting adapter can be designed in such a way that the safety railing can be used with scaffolding from various manufacturers. Furthermore, the erection and dismantling of scaffolding is possible with the help of such mounting adapters, to which the safety railing is temporarily attached, without great additional effort.

Zudem können bei dem mit dem Montageadapter verwendbaren Sicherheitsgeländer zwei obere Vertikalholme ausgebildet werden, so dass die voranstehend genannte Sicherheitsnorm erfüllt wird.In addition, two upper vertical rails can be formed in the safety railing that can be used with the assembly adapter, so that the aforementioned safety standard is met.

Demgemäß schlägt der Erfinder einen Montageadapter zur temporären Befestigung eines vorauseilenden Sicherheitsgeländers an einem Baugerüst beim Auf- und/oder Abbau des Baugerüstes vor. Der erfindungsgemäße Montageadapter ist einerseits zum temporären Anschlagen an einem Vertikalholm des Baugerüsts und andererseits zum temporären Befestigen des Sicherheitsgeländers an dem Montageadapter ausgebildet. Weiterhin ist hierfür mindestens eine Aufnahmeeinheit zum Aufnehmen von Befestigungselementen jeweils eines Sicherheitsgeländers und mindestens eine Befestigungseinrichtung zum Anschlagen des Montageadapters an dem Baugerüst ausgebildet.Accordingly, the inventor proposes a mounting adapter for the temporary fastening of a safety railing ahead of it on a scaffolding when erecting and/or dismantling the scaffolding. The assembly adapter according to the invention is designed on the one hand for temporarily attaching to a vertical beam of the scaffolding and on the other hand for temporarily attaching the safety railing to the assembly adapter. Furthermore, at least one receiving unit for receiving fastening elements of a safety railing and at least one fastening device for attaching the assembly adapter to the scaffolding is designed for this purpose.

Die mindestens eine Aufnahmeeinheit sowie vor allem die mindestens eine Befestigungseinrichtung können vorteilhafterweise sehr variabel ausgestaltet werden, sodass der Montageadapter an Baugerüsten diverser Hersteller verwendet werden kann. In einer einfachen, jedoch bevorzugten Ausführungsform ist die Aufnahmeeinheit als Vierkantrohr ausgebildet. Das Vierkantrohr ist vorteilhafterweise aus einem möglichst stabilen Material wie Metall, vorzugsweise Stahl, hergestellt. Weiterhin bevorzugt ist das Vierkantrohr einstückig hergestellt, um mögliche Materialschwächen oder Sollbruchstellen zu verhindern. Im Übrigen weist die als Vierkantrohr ausgebildete Aufnahmeeinheit vorteilhafterweise eine Längserstreckung entlang einer Längsachse auf, die deutlich größer ist als deren Durchmesser.The at least one receiving unit and above all the at least one fastening device can advantageously be configured very variably, so that the mounting adapter can be used on scaffolding from various manufacturers. In a simple but preferred embodiment, the receiving unit is designed as a square tube. The square tube is advantageously made of a material that is as stable as possible, such as metal, preferably steel. Furthermore, the square tube is preferably manufactured in one piece in order to prevent possible material weaknesses or predetermined breaking points. In addition, the receiving unit designed as a square tube advantageously has a longitudinal extension along a longitudinal axis that is significantly larger than its diameter.

Erfindungsgemäß weist die mindestens eine Aufnahmeeinheit mindestens zwei Nuten auf, die im montierten Zustand des Montageadapters betrachtet übereinander beziehungsweise untereinander angeordnet sind. Die Nuten sind vorteilhafterweise gleich ausgebildet, insbesondere gleich lang und gleich breit.According to the invention, the at least one receiving unit has at least two grooves, which are arranged one above the other or one below the other when viewed in the mounted state of the mounting adapter. The grooves are advantageously of the same design, in particular of the same length and width.

Im montierten Zustand betrachtet sind die beiden Nuten vorzugsweise übereinander beziehungsweise untereinander angeordnet. Das heißt, die Längserstreckungen beziehungsweise die Längsachsen der Nuten verlaufen vorzugsweise in einer Linie. Dabei sind die Nuten vorteilhafterweise länglich beziehungsweise schlitzförmig ausgebildet. In die Nuten der mindestens einen Aufnahmeeinheit werden vorteilhafterweise die Befestigungselemente des Sicherheitsgeländers aufgenommen. Die schlitzförmigen Nuten dienen dabei als eine Art Führung für die Befestigungselemente beim Einhängen.Viewed in the mounted state, the two grooves are preferably arranged one above the other or below one another. This means that the longitudinal extensions or the longitudinal axes of the grooves preferably run in one line. The grooves are advantageously elongate or slit-shaped. The fastening elements of the safety railing are advantageously received in the grooves of the at least one receiving unit. The slit-shaped grooves serve as a kind of guide for the fasteners when hanging.

Eine weitere bevorzugte Ausführungsform sieht daher vor, dass die mindestens zwei Nuten im montierten Zustand des Montageadapters betrachtet an ihren oberen Enden jeweils eine Öffnung zum Einführen der Befestigungselemente des Sicherheitsgeländers aufweisen. Beim Befestigen des Sicherheitsgeländers an den Montageadaptern werden die Befestigungselemente vorzugsweise einfach von oben in die Nuten eingeführt. Die unteren, geschlossenen Enden der Nuten bilden dementsprechend einen Anschlag für die Befestigungselemente aus. In einer Variante sind die Öffnungen der Nuten im montierten Zustand des Montageadapters betrachtet gebäudeseitig, also hinten, angeordnet. In einer anderen Variante sind die Öffnungen im montierten Zustand des Montageadapters betrachtet außen, also vorne beziehungsweise vom Gebäude weg orientiert, angeordnet. Noch eine Variante sieht eine seitliche Anordnung der Nuten an der Aufnahmeeinheit vor.A further preferred embodiment therefore provides that the at least two grooves, viewed in the mounted state of the mounting adapter, each have an opening at their upper ends for inserting the fastening elements of the safety railing. When attaching the safety rail to the mounting adapters the fasteners are preferably simply inserted into the grooves from above. Accordingly, the lower, closed ends of the grooves form a stop for the fastening elements. In one variant, the openings of the grooves are arranged on the building side, ie at the rear, when viewed in the assembled state of the assembly adapter. In another variant, the openings are arranged on the outside when the mounting adapter is in the mounted state, that is to say in the front or oriented away from the building. Another variant provides for a lateral arrangement of the grooves on the receiving unit.

Es wird darauf hingewiesen, dass jegliche verwendete relative Ortsbegriffe sich stets auf den montierten Zustand des Montageadapters beziehungsweise weitergehend auf den befestigten Zustand des Sicherheitsgeländers an dem Baugerüst beziehen.It is pointed out that any relative location terms used always refer to the mounted state of the mounting adapter or, more extensively, to the fastened state of the safety railing on the scaffolding.

In einer Ausführungsform des Montageadapters ist genau eine Aufnahmeeinheit zum Aufnehmen von Befestigungselementen eines Sicherheitsgeländers ausgebildet.In one embodiment of the mounting adapter, exactly one receiving unit is designed to receive fastening elements of a safety railing.

In einer anderen Ausführungsform des Montageadapters sind zwei Aufnahmeeinheiten zum Aufnehmen von Befestigungselementen von zwei Sicherheitsgeländern ausgebildet.In another embodiment of the mounting adapter, two receiving units are designed to receive fastening elements from two safety rails.

Zur Gewichtseinsparung können in den Aufnahmeeinheiten beispielsweise Aussparungen ausgebildet sein.Recesses, for example, can be formed in the receiving units to save weight.

Jede Aufnahmeeinheit kann zwei oder mehr Nuten aufweisen. Dabei sind jeweils mindestens zwei Nuten an einer Seite einer Aufnahmeeinheit angeordnet. Gemäß einer bevorzugten Ausführungsform weist jede Aufnahmeeinheit mindestens eine Montageebene auf, in der sich die Nuten erstrecken, wobei die mindestens eine Montageebene seitlich versetzt und parallel zu einer Befestigungsachse des Montageadapters angeordnet ist. Die Befestigungsachse des Montageadapters entspricht in einer bevorzugten Ausführungsform dem Vertikalholm des Baugerüstes, an dem der Montageadapter im montierten Zustand befestigt ist. Entsprechend verläuft die Befestigungsachse vorteilhafterweise außerhalb der Aufnahmeeinheit(en).Each receiving unit can have two or more grooves. At least two grooves are arranged on one side of a receiving unit. According to a preferred embodiment, each receiving unit has at least one mounting plane in which the grooves extend, the at least one mounting plane being offset laterally and arranged parallel to a fastening axis of the mounting adapter. In a preferred embodiment, the fastening axis of the mounting adapter corresponds to the vertical beam of the scaffolding to which the mounting adapter is fastened in the mounted state. Accordingly, the fastening axis advantageously runs outside of the receiving unit(s).

Eine Variante sieht vor, dass eine Aufnahmeeinheit genau eine Montageebene aufweist. Eine andere Variante sieht vor, dass eine Aufnahmeeinheit zwei oder drei Montageebenen aufweist.A variant provides that a recording unit has exactly one mounting level. Another variant provides that a recording unit has two or three mounting levels.

Vorteilhafterweise verläuft/verlaufen die Montageebene(n) jeweils parallel zu einer Außenseite der Aufnahmeeinheit. Gemäß einer besonders vorteilhaften Ausführungsform entspricht die Montageebene einer Außenseite der Aufnahmeeinheit.Advantageously, the assembly plane(s) runs/run parallel to an outside of the receiving unit. According to a particularly advantageous embodiment, the mounting plane corresponds to an outside of the receiving unit.

In einer Ausführungsform weisen zwei benachbarte Aufnahmeeinheiten jeweils eine Montageebene auf, wobei die Montageebenen parallel zueinander ausgerichtet sind. Grundsätzlich entsprechen benachbarte Aufnahmeeinheiten entweder den zwei Aufnahmeeinheiten eines Montageadapters oder den zwei Aufnahmeeinheiten von zwei Montageadaptern, zwischen beziehungsweise an denen ein Sicherheitsgeländer befestigt wird.In one embodiment, two adjacent receiving units each have a mounting plane, with the mounting planes being aligned parallel to one another. In principle, adjacent receiving units correspond either to the two receiving units of a mounting adapter or to the two receiving units of two mounting adapters, between or on which a safety railing is attached.

In einer weiteren Ausführungsform weisen zwei benachbarte Aufnahmeeinheiten jeweils eine Montageebene auf, wobei diese beiden Montagebenen in einem Winkel zueinander stehen. Ein Montageadapter mit zwei im Winkel zueinander stehenden Montagebenen ist vorteilhafterweise dazu geeignet, ein Sicherheitsgeländer an einem Baugerüst an einer Gebäudeecke anzubringen. Bei der Gebäudeecke kann es sich entweder um ein Inneneck oder um ein Außeneck des Gebäudes handeln. Vorzugsweise stehen die Montageebenen in dieser Ausführungsform in einem Winkel von 90° zueinander. Eine Ausbildung mit einem Winkel ungleich 90° liegt jedoch ebenso im Rahmen der Erfindung, um Sicherheitsgeländer an Baugerüste für Gebäude mit nicht-rechtwinkeligen Innen- und/oder Außenecken zu befestigen.In a further embodiment, two adjacent receiving units each have a mounting plane, with these two mounting planes being at an angle to one another. A mounting adapter with two mounting levels at an angle to one another is advantageously suitable for attaching a safety railing to scaffolding at a corner of a building. The corner of the building can be either an inside corner or an outside corner of the building. In this embodiment, the mounting planes are preferably at an angle of 90° to one another. However, a design with an angle other than 90° is also within the scope of the invention in order to attach safety rails to scaffolding for buildings with non-rectangular inside and/or outside corners.

Eine besondere Ausführungsform sieht vor, dass eine Aufnahmeeinheit zwei Montageebenen aufweist, die in einem Winkel, vorzugsweise im 90°-Winkel, zueinander stehen.A special embodiment provides that a receiving unit has two assembly planes which are at an angle, preferably at a 90° angle, to one another.

Jede Aufnahmeeinheit weist erfindungsgemäß mindestens zwei Nuten auf, wobei die Nuten in einer Montageebene angeordnet sind.According to the invention, each receiving unit has at least two grooves, the grooves being arranged in a mounting plane.

Gemäß einer Ausführungsform weist die mindestens eine Aufnahmeeinheit in einer Montageebene zwei Nuten auf.According to one embodiment, the at least one receiving unit has two grooves in a mounting plane.

Gemäß einer weiteren Ausführungsform weist die mindestens eine Aufnahmeeinheit in einer Montageebene mindestens eine zusätzliche Nut auf. Beispielsweise sind also in einer Montageebene drei oder vier etc. Nuten, vorzugsweise jedoch drei Nuten, ausgebildet. Entsprechend ist auch eine Ausführungsform möglich, bei der eine Aufnahmeeinheit zwei Montageebenen mit unterschiedlichen vielen Nuten aufweist, beispielsweise zwei Nuten in der einen Montageebene und drei Nuten in der anderen Montageebene.According to a further embodiment, the at least one receiving unit has at least one additional groove in a mounting level. For example, three or four etc. grooves, but preferably three grooves, are formed in one assembly level. Correspondingly, an embodiment is also possible in which a receiving unit has two mounting planes with a different number of grooves, for example two grooves in one mounting plane and three grooves in the other mounting plane.

Eine weitere Vorschrift für Sicherheitsgeländer besagt, dass die Befestigung von Sicherheitsgeländer einen Mindesthub aufweisen muss, mit dem sich das Sicherheitsgeländer nach oben bewegen können muss, ohne dass sich die Befestigung des Sicherheitsgeländers löst. Entsprechend sieht eine Ausführungsform vor, dass die Nuten derart ausgebildet sind, dass zum Aushängen der Befestigungselemente des Sicherheitsgeländers aus den Nuten eine Hubhöhe des Sicherheitsgeländers von mindestens 15 cm notwendig ist. Mit anderen Worten weisen die Nuten - im montierten Zustand, also mit der Öffnung nach oben - bevorzugt eine Tiefe beziehungsweise Länge von mindestens 15 cm auf. Dieser Wert der Mindesttiefe der Nuten entspricht der Summe aus der maximalen Hubhöhe eines Befestigungselementes in der Nut und dem Durchmesser des Befestigungselementes.Another regulation for safety rails states that the safety rail attachment must have a minimum stroke that the safety rail must be able to move upwards without the safety rail attachment loosening. Accordingly, one embodiment provides that the grooves are designed in such a way that a lifting height of the safety railing of at least 15 cm is necessary to detach the fastening elements of the safety railing from the grooves. In other words, the grooves—in the installed state, that is to say with the opening at the top—preferably have a depth or length of at least 15 cm. This value of the minimum depth of the grooves corresponds to the sum of the maximum lifting height of a fastener in the groove and the diameter of the fastener.

Sowohl das Anschlagen der Montageadapter an dem Baugerüst als auch das Befestigen des Sicherheitsgeländers an den Montageadaptern erfolgt manuell. Um das Einhängen des Sicherheitsgeländers in die Montageadapter, also das Einführen der Befestigungselemente in die Nuten zu erleichtern, ist vorteilhafterweise an einem unteren Bereich der Öffnung der Nuten jeweils eine Einführschiene ausgebildet. Die Einführschiene ist in einer einfachen Ausführungsform als eine Art Lippe ausgebildet. Die Lippe kann beispielsweise an eine Aufnahmeeinheit aus Metall einfach an die Öffnung der Nut angeschweißt werden.Both the mounting adapters are attached to the scaffolding and the safety railings are attached to the mounting adapters manually. In order to facilitate the hanging of the safety railing into the mounting adapter, ie the insertion of the fastening elements into the grooves, an insertion rail is advantageously formed in each case on a lower region of the opening of the grooves. In a simple embodiment, the insertion rail is designed as a type of lip. The lip can, for example, be welded to a metal receiving unit simply at the opening of the groove.

Der erfindungsgemäße Montageadapter weist mindestens eine Befestigungseinrichtung zum Anschlagen des Montageadapters an das Baugerüst, vorzugsweise an einen Vertikalholm des Baugerüsts, auf. Um eine sichere Befestigung zu gewährleisten, weist der Montageadapter mehr als eine Befestigungseinrichtung, vorteilhafterweise zwei Befestigungseinrichtungen, auf.The mounting adapter according to the invention has at least one fastening device for attaching the mounting adapter to the scaffolding, preferably to a vertical beam of the scaffolding. In order to ensure secure attachment, the mounting adapter has more than one attachment device, advantageously two attachment devices.

Eine Ausführungsform sieht vor, dass eine erste Befestigungseinrichtung als manuell lösbare Schraub-Klemm-Verbindung ausgebildet ist. Eine derartige Verbindung ist vorteilhafterweise werkzeuglos und einhändig bedienbar.One embodiment provides that a first fastening device is designed as a manually detachable screw clamp connection. Such a connection can advantageously be operated without tools and with one hand.

Eine weitere Ausführungsform sieht eine weitere Befestigungseinrichtung vor, die als Sicherungseinheit ausgebildet ist, welche am Baugerüst einen Anschlag gegen ein Herunterfallen ausbildet. Die Sicherungseinheit ist vorteilhafterweise als eine Art Haken ausgebildet. Dieser Haken kann beispielsweise in ein Knotenblech unter einem Gerüstboden oder in einen Horizontalholm des Baugerüsts eingehängt werden. Weiterhin vorteilhaft ermöglicht die Sicherungseinheit das Anschlagen des Montageadapters in einer definierten Höhe an dem Vertikalholm. Ebenso kann der Montageadapter mittels der Sicherungseinheit zunächst einfach an das Baugerüst gehängt werden, um ein Herunterfallen zu verhindern, und anschließend mittels der ersten Befestigungseinrichtung an dem Vertikalholm fixiert werden.A further embodiment provides a further fastening device which is designed as a safety unit which forms a stop on the scaffolding to prevent it from falling down. The safety unit is advantageously designed as a type of hook. This hook can be hung, for example, in a gusset plate under a scaffolding floor or in a horizontal beam of the scaffolding. The securing unit also advantageously allows the mounting adapter to be attached to the vertical beam at a defined height. Likewise, the mounting adapter using the Safety unit are initially simply hung on the scaffolding to prevent falling, and then be fixed by means of the first fastening device on the vertical beam.

Noch eine weitere Ausführungsform sieht mindestens eine weitere Befestigungseinrichtung vor, welche am Baugerüst einen Anschlag gegen ein seitliches Verrutschen ausbildet. Bevorzugt wird der Anschlag zumindest an einem Vertikalholm, an dem der Montageadapter befestigt wird, ausgebildet. Dadurch kann vorteilhafterweise bei der Montage des Montageadapters ein seitliches Verrutschen verhindert werden. In einer Variante ist im oberen Bereich des Montageadapters eine V-förmige, nach oben offene Nut ausgebildet, in welche bei der Montage vorteilhafterweise ein Teil des Baugerüstes, insbesondere ein Horizontalholm oder ein Knotenblech, positioniert werden kann.Yet another embodiment provides at least one additional fastening device, which forms a stop on the scaffolding to prevent lateral slipping. The stop is preferably formed at least on a vertical bar to which the mounting adapter is attached. As a result, lateral slippage can advantageously be prevented during assembly of the assembly adapter. In one variant, a V-shaped, upwardly open groove is formed in the upper area of the assembly adapter, in which advantageously part of the scaffolding, in particular a horizontal beam or a gusset plate, can be positioned during assembly.

Die Nut kann beispielsweise an eine Art Griff beziehungsweise bogenförmigem Anschlag ausgebildet sein, welcher um den Vertikalholm, an dem der Montageadapter befestigt wird, herumgreift. In einer anderen, zusätzlichen oder alternativen Variante ist in einem unteren Bereich des Montageadapters eine Art Doppelwange mit mittiger Vertiefung ausgebildet, wobei der Vertikalholm, an dem der Montageadapter befestigt wird, vorteilhafterweise in der Vertiefung positioniert wird. Vorzugsweise ermöglichen beide Varianten in Kombination, also der Griff mit der Nut und die Doppelwange eine optimale Positionierung und Sicherung des Montageadapters.The groove can be formed, for example, on a type of handle or curved stop, which grips around the vertical bar to which the mounting adapter is attached. In another, additional or alternative variant, a type of double cheek with a central depression is formed in a lower region of the mounting adapter, with the vertical bar, to which the mounting adapter is fastened, advantageously being positioned in the depression. Both variants in combination, ie the handle with the groove and the double cheek, preferably enable optimal positioning and securing of the mounting adapter.

Weiterhin betrifft die Erfindung ein Sicherheitsgeländer zur temporären Befestigung an einem Baugerüst beim Auf- und/oder Abbau des Baugerüstes, wobei das Sicherheitsgeländer beim Aufbau jeweils eine nächste Gerüstetage bis zu deren Fertigstellung oder jeweils eine oberste Gerüstetage bis zu deren vollständigen Abbau sichert, wobei das Sicherheitsgeländer derart ausgebildet ist, dass es mittels mindestens eines erfindungsgemäßen, voranstehend beschriebenen Montageadapters temporär an dem Baugerüst befestigbar ist.The invention also relates to a safety railing for temporary attachment to scaffolding when erecting and/or dismantling the scaffolding, with the safety railing securing the next scaffolding floor until its completion or the top scaffolding floor until it is completely dismantled, the safety railing is designed in such a way that it can be temporarily fastened to the scaffolding by means of at least one assembly adapter according to the invention and described above.

Das erfindungsgemäße Sicherheitsgeländer weist mindestens einen Horizontalholm sowie zwei seitlich angeordnete Vertikalholme, zwischen denen sich der mindestens eine Horizontalholm erstreckt, auf, wobei an den Vertikalholmen seitlich angeordnete Befestigungselemente ausgebildet sind, die beim Auf- und Abbau des Baugerüstes temporär in den Aufnahmeeinheiten der Montageadapter einsetzbar sind. Vorteilhafterweise wird das Sicherheitsgeländer an beiden Seiten an jeweils einem Montageadapter befestigt. Die Befestigungselemente des Sicherheitsgeländers werden hierfür in die Aufnahmeeinheiten, genauer gesagt in die Nuten der Aufnahmeeinheiten, eingesetzt.The safety railing according to the invention has at least one horizontal rail and two laterally arranged vertical rails, between which the at least one horizontal rail extends, with fastening elements arranged laterally being formed on the vertical rails, which can be used temporarily in the receiving units of the assembly adapters when erecting and dismantling the scaffolding . Advantageously, the safety railing is attached to a mounting adapter on both sides. The safety rail fasteners are used for this purpose in the receiving units, more precisely in the grooves of the receiving units.

Daher sieht eine bevorzugte Ausführungsform vor, dass die Befestigungselemente im Wesentlichen komplementär zu den Aufnahmeeinheiten, insbesondere zu den Nuten an den Aufnahmeeinheiten, ausgebildet sind.A preferred embodiment therefore provides that the fastening elements are designed to be essentially complementary to the receiving units, in particular to the grooves on the receiving units.

Erfindungsgemäß sind die Befestigungselemente zapfenförmig mit einer endständigen Verdickung ausgebildet, wobei der Zapfen zum Einführen in die Nut ausgebildet ist. Der Durchmesser der Zapfen ist vorteilhafterweise kleiner als die Breite der Nut, um ein möglichst reibungsloses Gleiten der Zapfen in der Nut zu ermöglichen. Bevorzugt ist der Durchmesser der Zapfen jedoch lediglich wenige Millimeter kleiner als die Breite der Nut, um unnötigen Spielraum zu vermeiden, welcher zu einer Instabilität des Sicherheitsgeländers führen würde, jedoch um ein ungehindertes Gleiten in der Nut zu ermöglichen. Endständig, also an den Enden, weist der Zapfen vorteilhafterweise eine Verdickung auf, um ein unbeabsichtigtes Herausziehen oder seitliches Lösen der Zapfen aus der Nut zu verhindern. Wird der Zapfen in die Nut eingeführt, befindet sich die Verdickung vorteilhafterweise im Inneren der Aufnahmeeinheit. Beispielsweise sind die zapfenförmigen Befestigungselemente mit endständiger Verdickung als Pilzkopfschrauben ausgebildet.According to the invention, the fastening elements are designed in the form of pegs with a thickening at the end, the peg being designed for insertion into the groove. The diameter of the pegs is advantageously smaller than the width of the groove in order to allow the pegs to slide as smoothly as possible in the groove. Preferably, however, the diameter of the pegs is only a few millimeters smaller than the width of the groove in order to avoid unnecessary play, which would lead to instability of the safety rail, but to allow unhindered sliding in the groove. At the end, that is to say at the ends, the peg advantageously has a thickened portion in order to prevent the peg from being unintentionally pulled out or laterally released from the groove. If the pin is inserted into the groove, the thickening is advantageously inside the receiving unit. For example, the pin-shaped fastening elements with a terminal thickening are designed as mushroom head screws.

Bevorzugterweise entspricht die Anzahl der Befestigungselemente je Vertikalholm der Anzahl der Nuten je Aufnahmeeinheit. Somit kann jedes Befestigungselement zum Befestigen des Sicherheitsgeländers an den Montageadaptern in eine Nut eingeführt werden, um eine sichere, insbesondere kippsichere, Befestigung zu gewährleisten.The number of fastening elements per vertical bar preferably corresponds to the number of grooves per receiving unit. In this way, each fastening element for fastening the safety railing to the mounting adapters can be inserted into a groove in order to ensure secure fastening, in particular non-tilting fastening.

Wie voranstehend bereits ausgeführt, besagt eine Sicherheitsvorschrift für Sicherheitsgeländer, dass die Befestigung einem Hub von mindestens 15 cm standhalten muss, bevor sich das Sicherheitsgeländer aus der Befestigung löst.As noted above, a safety requirement for safety rails is that the fixture must withstand a stroke of at least 15 cm before the safety rail will disengage from the fixture.

Eine weitere Sicherheitsvorschrift besagt, dass sich der oberste Punkt des Sicherheitsgeländers bei einer Querbelastung von 30 kg nur maximal 3,5 cm nach außen, also vom Gebäude weg, bewegen darf. Um diese Sicherheitsvorschrift einzuhalten, sieht daher eine bevorzugte Ausführungsform vor, dass der Wert A = (D-d) * H/h maximal 3,5 cm beträgt, wobei gilt:

  • D: Breite der Nut,
  • d: Durchmesser des Zapfens in der Nut,
  • h: Abstand vom oberen zum unteren Zapfen,
  • H: Abstand vom oberen Zapfen zum oberen Vertikalholm, und
  • A: Auslenkung des Geländers am höchsten Punkt bei einer Belastung mit einem Gewicht von 30 kg.
Another safety regulation states that the uppermost point of the safety railing may only move a maximum of 3.5 cm outwards, i.e. away from the building, with a lateral load of 30 kg. In order to comply with this safety regulation, a preferred embodiment therefore provides that the value A=(Dd)*H/h is a maximum of 3.5 cm, where:
  • D: width of the groove,
  • d: diameter of the pin in the groove,
  • h: distance from the top to the bottom pin,
  • H: Distance from the top pivot to the top vertical rail, and
  • A: Deflection of the railing at the highest point with a load of 30 kg.

In einer bevorzugten Ausführungsform sind die Befestigungselemente im unteren Bereich der Vertikalholme des Sicherheitsgeländers angeordnet. Das Sicherheitsgeländer wird also im unteren Bereich an den Montageadaptern befestigt und erstreckt sich dann vorteilhafterweise im Wesentlichen nach oben in Richtung der jeweils abzusichernden obersten Gerüstetage.In a preferred embodiment, the fastening elements are arranged in the lower area of the vertical rails of the safety railing. The safety railing is thus fastened to the mounting adapters in the lower area and then advantageously extends essentially upwards in the direction of the top scaffolding floor to be secured.

Noch eine Sicherheitsvorschrift besagt, dass ein Sicherheitsgeländer mindestens zwei Horizontalholme im oberen Bereich, also als temporäres Geländer als Absturzsicherung für einen Gerüstbauer, aufweisen muss. Entsprechend sieht eine bevorzugte Ausführungsform vor, dass zwei obere Horizontalholme und ein unterer Horizontalholm ausgebildet sind. Die beiden oberen Horizontalholme dienen als Absturzsicherung und bilden das eigentliche Geländer aus und der untere Horizontalholm dient im Wesentlichen zur Stabilisierung des Sicherheitsgeländers. Zur weiteren Stabilisierung des Sicherheitsgeländers sowie zur weiteren Absturzsicherung können vorteilhafterweise zumindest zwischen den beiden oberen Horizontalholmen Querverstrebungen ausgebildet sein.Another safety regulation states that a safety railing must have at least two horizontal rails in the upper area, i.e. as a temporary railing as fall protection for a scaffolder. Accordingly, a preferred embodiment provides that two upper horizontal bars and one lower horizontal bar are formed. The two upper horizontal rails serve as fall protection and form the actual railing, and the lower horizontal rail essentially serves to stabilize the safety railing. For further stabilization of the safety railing and for further fall protection, cross braces can advantageously be formed at least between the two upper horizontal rails.

Um eine einfache Handhabung des Sicherheitsgeländers zu ermöglichen, ist in einer vorteilhaften Ausführungsform am unteren Horizontalholm mindestens ein Handgriff zum Einsetzen des Sicherheitsgeländers in die Montageadapter ausgebildet. Der Handgriff ist beispielsweise als U-förmiger Holm ausgebildet, welcher leicht zu greifen ist.In order to enable easy handling of the safety railing, at least one handle for inserting the safety railing into the mounting adapter is formed on the lower horizontal bar in an advantageous embodiment. The handle is designed, for example, as a U-shaped bar, which is easy to grip.

Eine weitere Ausführungsform des Sicherheitsgeländers sieht vor, dass der mindestens eine Horizontalholm teleskopierbar ausgeführt ist. Somit kann die Breite des Sicherheitsgeländers vorteilhafterweise variabel eingestellt werden. Optional können an den teleskopierbaren Horizontalholmen Justierelemente ausgebildet sein, welche die Holme jeweils auf eine bestimmte Länge beziehungsweise Breite fixieren. Weiterführend ist der mindestens eine teleskopierbare Horizontalholm vorteilhafterweise über Gelenke mit den Vertikalholmen verbunden. Dies ermöglicht eine größere Variabilität des Sicherheitsgeländers in der Anwendung.A further embodiment of the safety railing provides that the at least one horizontal bar is designed to be telescopic. The width of the safety railing can thus advantageously be variably adjusted. Optionally, adjusting elements can be formed on the telescoping horizontal bars, which fix the bars to a specific length or width. Furthermore, the at least one telescoping horizontal beam is advantageously connected to the vertical beams via joints. This enables greater variability of the safety railing in use.

Zudem betrifft die Erfindung einen Bausatz zum Errichten eines Baugerüstes, zumindest aufweisend: mehrere Gerüstböden und mehrere Vertikal- und Horizontalholme einschließlich deren Verbindungselemente zur Errichtung mehrerer, übereinander liegender Gerüstetagen, mindestens ein voranstehend beschriebenes, erfindungsgemäßes Sicherheitsgeländer, und mindestens zwei voranstehend beschriebene, erfindungsgemäße Montageadapter zum temporären Befestigen des Sicherheitsgeländers an dem Baugerüst beim Auf- und/oder Abbau. Die Horizontalholme des Bausatzes bilden vorteilhafterweise das eigentliche Gerüstgeländer aus, welches dauerhaft an der jeweiligen Gerüstetage verbleibt.In addition, the invention relates to a kit for erecting scaffolding, at least comprising: several scaffolding decks and several vertical and horizontal beams including their connecting elements for erecting several one above the other lying scaffolding floors, at least one safety railing according to the invention as described above, and at least two assembly adapters according to the invention described above for temporarily fastening the safety railing to the scaffolding during erection and/or dismantling. The horizontal rails of the kit advantageously form the actual scaffolding railings, which remain permanently on the respective scaffolding floor.

Die Erfindung betrifft auch ein Baugerüst, errichtet aus einem voranstehend beschriebenen, erfindungsgemäßen Bausatz. Je Gerüstetage ist mindestens ein Gerüstetagensegment vorgesehen. Mit anderen Worten wird eine komplette Gerüstetage aus mindestens einem, vorteilhafterweise mehreren Gerüstetagensegmenten gebildet. Die jeweils oberste Gerüstetage beziehungsweise ein jeweils oberstes Gerüstetagensegment wird bis zur Fertigstellung, insbesondere bis zur Absicherung mit dem eigentlichen Gerüstgeländer, temporär durch das erfindungsgemäße Sicherheitsgeländer gesichert.The invention also relates to scaffolding erected from a kit according to the invention described above. At least one scaffolding level segment is provided for each scaffolding level. In other words, a complete scaffolding level is formed from at least one, advantageously a plurality of scaffolding level segments. The respective uppermost scaffolding floor or a respective uppermost scaffolding floor segment is temporarily secured by the safety railing according to the invention until completion, in particular until it is secured with the actual scaffolding railing.

Der Auf- und Abbau des erfindungsgemäßen Baugerüstes mit den erfindungsgemäßen Sicherheitsgeländern ist entweder etagenweise oder segmentweise möglich. Die einzelnen Verfahrensschritte der erfindungsgemäßen Verfahren zum Auf- und Abbau werden jeweils für ein Gerüstetagensegment beschrieben und können in beliebiger Reihenfolge und Anzahl wiederholt werden, um das Baugerüst vollständig und mit allen Gerüstetagensegmenten aufzubauen und zu sichern.The erection and dismantling of the scaffolding according to the invention with the safety railings according to the invention is possible either in tiers or in segments. The individual process steps of the method according to the invention for erection and dismantling are each described for a scaffolding floor segment and can be repeated in any order and number in order to build up and secure the scaffolding completely and with all scaffolding floor segments.

Schließlich betrifft die Erfindung noch ein Verfahren zum Aufbau eines voranstehend beschriebenen, erfindungsgemäßen Baugerüstes aus einem voranstehend beschriebenen, erfindungsgemäßen Bausatz, zumindest aufweisend die folgenden Verfahrensschritte:

  • Anbringen eines Gerüstbodens eines nächsten oberen Gerüstetagensegments auf bereits errichteten Vertikalholmen eines letzten gesicherten Gerüstetagensegments,
  • Anschlagen jeweils eines Montageadapters an zwei benachbarten bereits errichteten Vertikalholmen,
  • Einsetzen eines Sicherheitsgeländers in die beiden Montageadapter zum Schutz des nächsten oberen Gerüstetagensegments von dem letzten gesicherten Gerüstetagensegments aus,
  • Fertigstellen des oberen Gerüstetagensegments einschließlich Einrichten eines Gerüstgeländers zwischen den Vertikalholmen, und

Die Figur 1 zeigt eine schematische Perspektivansicht eines Montageadapters 1. Der Montageadapter 1 umfasst zwei gegenüberliegend und parallel zueinander angeordnete Aufnahmeeinheiten 10. An den Aufnahmeeinheiten 10 sind jeweils zwei untereinander angeordnete Nuten 11 ausgebildet. Die Nuten 11 erstrecken sich jeweils in einer seitlichen Montageebene M1 der Aufnahmeeinheiten 10. An ihren oberen Enden weisen die Nuten 11 eine Öffnung 12 auf, durch die die Befestigungselemente eines Sicherheitsgeländers in die Nuten 11 eingeführt werden können.the figure 1 shows a schematic perspective view of a mounting adapter 1. The mounting adapter 1 comprises two receiving units 10 arranged opposite one another and parallel to one another. Two grooves 11 arranged one below the other are formed on the receiving units 10 in each case. The grooves 11 each extend in a lateral mounting plane M1 of the receiving units 10. At their upper ends, the grooves 11 have an opening 12 through which the fastening elements of a safety railing can be inserted into the grooves 11.

Weiterhin weist der Montageadapter 1 eine Befestigungseinrichtung zum Anschlagen des Montageadapters 1 an einem Baugerüst auf. Die Befestigungseinrichtung weist in dieser Ausführungsform des Montageadapters 1 drei Befestigungseinheiten auf.Furthermore, the mounting adapter 1 has a fastening device for attaching the mounting adapter 1 to scaffolding. In this embodiment of the mounting adapter 1, the fastening device has three fastening units.

Eine obere Befestigungseinheit ist als eine Art Arm oder Bogen ausgeführt, welcher um einen Vertikalholm des Baugerüstes herumgreift und so einen oberen Anschlag 21 ausbildet, um den Montageadapter 1 beim Befestigen zunächst zu stabilisieren. An dem bogenförmigen Anschlag 21 sind zudem zwei Nasen ausgebildet, welche eine nach unten offene V-förmige Nut 22 bilden. Die Nasen beziehungsweise die Nut 22 dienen als Haken zum Einhängen des Montageadapters 1 an dem Baugerüst, beispielsweise in ein Knotenblech des Baugerüstes, um so den Montageadapter 1 vor dessen endgültiger Befestigung zu sichern.An upper attachment unit is designed as a kind of arm or bow, which grips around a vertical beam of the scaffolding and thus forms an upper stop 21 in order to initially stabilize the mounting adapter 1 during attachment. In addition, two lugs are formed on the arcuate stop 21, which form a V-shaped groove 22 which is open towards the bottom. The lugs or the groove 22 serve as hooks for hanging the mounting adapter 1 on the scaffolding, for example in a gusset plate of the scaffolding, in order to secure the mounting adapter 1 before its final attachment.

Eine mittlere Befestigungseinheit ist als Schraub-Klemm-Kupplung 25 ausgebildet. Hiermit wird der Montageadapter 1 an einem Vertikalholm des Baugerüstes angeschlagen. Die Schraub-Klemm-Kupplung 25 ist an einer Rechteckscheibe 24 zwischen den beiden Aufnahmeeinheiten 10 angeschraubt.A central fastening unit is designed as a screw clamp coupling 25 . The mounting adapter 1 is hereby attached to a vertical beam of the scaffolding. The screw clamp coupling 25 is screwed to a rectangular disk 24 between the two receiving units 10 .

Eine untere Befestigungseinheit ist als Doppelwange 23 ausgebildet, in deren Mitte der Vertikalholm angeordnet wird, um den Montageadapter 1 zu stabilisieren.A lower fastening unit is designed as a double cheek 23, in the middle of which the vertical bar is arranged in order to stabilize the mounting adapter 1.

Die Aufnahmeeinheiten 10 und die drei Befestigungseinheiten sind in dieser Ausführungsform miteinander verschweißt.In this embodiment, the receiving units 10 and the three fastening units are welded to one another.

Die Figur 2 zeigt eine schematische Vorderansicht des Montageadapters 1 gemäß der Figur 1. Die Vorderseite des Montageadapters 1 ist in dessen montierten Zustand vom Baugerüst weg orientiert, also außen. Zu sehen sind in dieser Ansicht vor allem die Öffnungen 12 der Nuten 11, welche auf der Vorder- beziehungsweise Außenseite der Aufnahmeeinheiten 10 angeordnet sind. Die Montageebene M1 ist jeweils seitlich an den Aufnahmeeinheiten 10 angeordnet.the figure 2 shows a schematic front view of the mounting adapter 1 according to FIG figure 1 . The front of the mounting adapter 1 is oriented away from the scaffolding in its mounted state, ie on the outside. The openings 12 of the grooves 11 , which are arranged on the front or outside of the receiving units 10 , can be seen in this view. The mounting level M1 is arranged laterally on the receiving units 10 in each case.

Die Figur 3 zeigt eine schematische Perspektivansicht eines Montageadapters 1 in einer anderen Ausführungsform. Im Folgenden wird lediglich auf die Unterschiede dieser Ausführungsform zu dem Montageadapter 1 gemäß der Figur 1 eingegangen. In der Ausführungsform gemäß der Figur 3 sind die beiden Nasen beziehungsweise die V-förmige Nut 22 an dem bogenförmigen Anschlag 21 der oberen Befestigungseinheit nach oben hin ausgerichtet. Zur Stabilisierung kann die Nut 22 von unten zum Beispiel um ein Knotenblech des Baugerüstes geschoben werden. Zur besseren Übersicht ist auf die Darstellung der Schraub-Klemm-Kupplung verzichtet. Zwischen den Aufnahmeeinheiten 10 ist lediglich die Rechteckscheibe 24 dargestellt, an der die Schraub-Klemm-Kupplung befestigt wird.the figure 3 shows a schematic perspective view of a mounting adapter 1 in another embodiment. In the following, only the differences between this embodiment and the mounting adapter 1 according to FIG figure 1 received. In the embodiment according to FIG figure 3 the two lugs or the V-shaped groove 22 on the arcuate stop 21 of the upper fastening unit are aligned upwards. For stabilization, the groove 22 can be pushed from below, for example around a gusset plate of the scaffolding. For a better overview, the screw clamp coupling is not shown. Only the rectangular disc 24 is shown between the receiving units 10, to which the screw-clamp coupling is fastened.

Die Figur 4 zeigt eine schematische Rückansicht des Montageadapters 1 gemäß der Figur 3, die Figur 5 eine schematische Seitenansicht und die Figur 6 eine schematische Draufsicht.the figure 4 shows a schematic rear view of the mounting adapter 1 according to FIG figure 3 , the figure 5 a schematic side view and the figure 6 a schematic plan view.

Die Figur 7 zeigt eine schematische Perspektivansicht einer Aufnahmeeinheit 10 des Montageadapters gemäß der Figur 1. Die Aufnahmeeinheit 10 ist aus einem Vierkantrohr hergestellt und einstückig ausgeführt. Das Vierkantrohr besteht aus einem stabilen Material wie Metall. In der einen Montageebene M1 der Aufnahmeeinheit 10 sind die zwei Nuten 11 ausgebildet, die sich über- beziehungsweise untereinander entlang der Längsachse des Vierkantrohres erstrecken. Im montierten Zustand verläuft die Längsachse des Vierkantrohres parallel seitlich versetzt zur Befestigungsachse des Montageadapters 1.the figure 7 shows a schematic perspective view of a receiving unit 10 of the mounting adapter according to FIG figure 1 . The receiving unit 10 is made from a square tube and is designed in one piece. The square tube is made of a stable material such as metal. The two grooves 11 are formed in one mounting plane M1 of the receiving unit 10 and extend above or below each other along the longitudinal axis of the square tube. When assembled, the longitudinal axis of the square tube runs parallel to the attachment axis of the assembly adapter 1 and is offset laterally.

Beide Nuten 11 weisen an ihren oberen Enden eine Öffnung 12 auf. Die Öffnungen 12 zeigen im montierten Zustand nach vorne beziehungsweise außen.Both grooves 11 have an opening 12 at their upper ends. In the installed state, the openings 12 point to the front or to the outside.

Die Figur 8 zeigt eine schematische Vorderansicht der Aufnahmeeinheit 10 gemäß der Figur 7 und die Figur 9 eine schematische Seitenansicht.the figure 8 shows a schematic front view of the recording unit 10 according to FIG figure 7 and the figure 9 a schematic side view.

Die Figur 10 zeigt eine schematische Perspektivansicht einer Aufnahmeeinheit 10 in einer weiteren Ausführungsform. Die Aufnahmeeinheit 10 weist zwei Montageebenen M1 und M2 auf, in denen sich jeweils zwei Nuten 11 erstrecken. Die Montageebenen M1, M2 beziehungsweise die Nuten 11 sind an zwei gegenüberliegenden Seiten der Aufnahmeeinheit 10 ausgebildet. Jeweils zwei gegenüberliegend angeordnete Nuten 11 weisen an ihren oberen Enden eine gemeinsame Öffnung 12 auf.the figure 10 shows a schematic perspective view of a recording unit 10 in a further embodiment. The receiving unit 10 has two mounting planes M1 and M2, in each of which two grooves 11 extend. The mounting planes M1, M2 or the grooves 11 are formed on two opposite sides of the receiving unit 10. Two oppositely arranged grooves 11 each have a common opening 12 at their upper ends.

Die Figur 11 zeigt eine schematische Vorderansicht der Aufnahmeeinheit 10 gemäß der Figur 10 und die Figur 12 eine schematische Seitenansicht.the figure 11 shows a schematic front view of the recording unit 10 according to FIG figure 10 and the figure 12 a schematic side view.

Die Figur 13 zeigt eine schematische Perspektivansicht des Montageadapters 1 in einer weiteren Ausführungsform. Gleiche Bauteile sind mit gleichen Bezugszeichen gekennzeichnet, von daher wird lediglich auf die Unterschiede zu den anderen Ausführungsformen eingegangen. In dieser Ausführungsform sind die Nuten 11 und deren Öffnungen 12 unterschiedlich ausgebildet. Die untere Nut 11 ist etwas kürzer ausgebildet als die obere Nut 11. Die Öffnung 12 der unteren Nut 11 ist nach zwei Seiten der Aufnahmeeinheit 10 ausgebildet. Die obere Nut 11 ragt bis zum Ende der Aufnahmeeinheit 10 beziehungsweise ist nach oben offen. Entsprechend entspricht die Öffnung 12 der oberen Nut 11 der oberen Öffnung des Vierkantrohres beziehungsweise der Aufnahmeeinheit 10. Weiterhin ist auf einer Vorder- beziehungsweise Außenseite der Aufnahmeeinheiten 10 an den oberen Enden der unteren und oberen Nuten 11 eine Einführschiene nach Art einer hervorragenden Lippe 26 ausgebildet. Die untere Lippe 26 ist als separates Teil ausgebildet und beispielsweise mit den Vierkantrohren verschweißt. Die obere Lippe 26 ist an die obere Befestigungseinheit, also den bogenförmigen Anschlag 21, integriert beziehungsweise einteilig mit diesem ausgebildet. Die Lippen 26 sind leicht nach hinten unten, also in Richtung der Öffnung geneigt.the figure 13 shows a schematic perspective view of the mounting adapter 1 in a further embodiment. Identical components are identified by the same reference symbols, so only the differences from the other embodiments will be discussed. In this embodiment, the grooves 11 and their openings 12 are designed differently. The lower groove 11 is somewhat shorter than the upper groove 11. The opening 12 of the lower groove 11 is formed on two sides of the receiving unit 10. The upper groove 11 projects to the end of the receiving unit 10 or is open at the top. Accordingly, the opening 12 of the upper groove 11 corresponds to the upper opening of the square tube or the receiving unit 10. Furthermore, on a front or outside of the receiving units 10 at the upper ends of the lower and upper grooves 11, an insertion rail is formed in the manner of a protruding lip 26. The lower lip 26 is designed as a separate part and welded to the square tubes, for example. The upper lip 26 is integrated into the upper fastening unit, that is to say the arc-shaped stop 21, or is formed in one piece with it. The lips 26 are slightly backwards and downwards, ie inclined in the direction of the opening.

Die Figur 14 zeigt eine weitere schematische Perspektivansicht des Montageadapters 1 gemäß der Figur 13 mit jeweils zwei Befestigungselementen 46 auf beiden Seiten. Die Befestigungselemente 46 sind als Pilzkopfschrauben ausgebildet mit einer endständigen Verdickung 46b und einem dünneren Zapfen 46a. Wie in der nachfolgenden Figur 15 zu sehen ist, werden die Befestigungselemente 46 durch Bohrungen in denthe figure 14 shows a further schematic perspective view of the mounting adapter 1 according to FIG figure 13 with two fasteners 46 on each side. The fasteners 46 are designed as mushroom head screws with a terminal thickening 46b and a thinner pin 46a. As in the following figure 15 can be seen, the fasteners 46 through holes in the

Vertikalholmen 41 hindurch gesteckt und an ihren inneren Enden mit Muttern 46c gesichert.Vertical bars 41 inserted through and secured at their inner ends with nuts 46c.

Beim Einführen der Befestigungselemente 46 in diese Montageadapter 1 dieser Ausführungsform werden zuerst die oberen Befestigungselemente 46 von oben in die Öffnungen 12 der Nuten 11 eingeführt. Dabei wird das Sicherheitsgeländer 40 oben nach hinten, also in Richtung Gebäude, gekippt. Anschließend wird das Sicherheitsgeländer 40 mit den oberen Befestigungselementen 46 in den oberen Nuten 11 etwas abgesenkt und in die Gegenrichtung gekippt, sodass die unteren Befestigungselemente 46 in die unteren Nuten 11 eingeführt werden können. Das Sicherheitsgeländer 40 kann anschließend vollständig zum Anschlag der Befestigungselemente 46 an den unteren Enden der Nuten 11 abgesenkt werden.When inserting the fastening elements 46 into this mounting adapter 1 of this embodiment, the upper fastening elements 46 are first inserted into the openings 12 of the grooves 11 from above. The safety railing 40 is tilted backwards at the top, ie in the direction of the building. Then the safety railing 40 with the upper fastening elements 46 in the upper grooves 11 is lowered somewhat and tilted in the opposite direction so that the lower fastening elements 46 can be inserted into the lower grooves 11 . The safety rail 40 can then be lowered fully to abut the fasteners 46 at the lower ends of the grooves 11.

Die Figur 15 zeigt eine schematische Seitenansicht eines Sicherheitsgeländers 40. Das Sicherheitsgeländer 40 umfasst zwei seitlich angeordnete Vertikalholme 41 und drei Horizontalholme, die sich zwischen den Vertikalholmen 41 erstrecken. Die zwei oberen Horizontalholme bilden die Geländerholme 42 aus und der untere Horizontalholm 43 dient vor allem zur Versteifung des Sicherheitsgeländers 40. Weiterhin sind zwischen den Geländerholmen 42 zwei Querverstrebungen 44 zur Stabilisierung und zum zusätzlichen Absturzschutz ausgebildet. An dem unteren Horizontalholm 43 ist ein U-förmiger Handgriff 45 angeordnet.the figure 15 shows a schematic side view of a safety railing 40. The safety railing 40 comprises two laterally arranged vertical rails 41 and three horizontal rails which extend between the vertical rails 41. The two upper horizontal rails form the railing rails 42 and the lower horizontal rail 43 serves primarily to reinforce the safety railing 40. Furthermore, two cross braces 44 are formed between the railing rails 42 for stabilization and additional fall protection. A U-shaped handle 45 is arranged on the lower horizontal beam 43 .

Erfindungsgemäß sind an den Vertikalholmen 41 im unteren Bereich jeweils zwei seitlich angeordnete Befestigungselemente 46 ausgebildet, die beim Auf- und Abbau des Baugerüstes temporär in die Nuten der Aufnahmeeinheiten der Montageadapter eingesetzt werden. Die Befestigungselemente 46 sind in dieser Ausführungsform als Pilzkopfschrauben ausgebildet, welche einen Zapfen 46a und eine endständige Verdickung 46b aufweisen.According to the invention, two laterally arranged fastening elements 46 are formed on the vertical bars 41 in the lower area, which are temporarily inserted into the grooves of the receiving units of the assembly adapter during erection and dismantling of the scaffolding. In this embodiment, the fastening elements 46 are designed as mushroom head screws, which have a pin 46a and a thickening 46b at the end.

Die Figur 16 zeigt einen Ausschnitt des Sicherheitsgeländers 40 gemäß der Figur 15 im Bereich der Befestigungselemente 46 an einem Vertikalholm 41 sowie einen Montageadapter 1. Die Befestigungselemente 46 sind komplementär zu den Nuten 11 ausgebildet. Zum Befestigen des Sicherheitsgeländers 40 werden die Befestigungselemente 46 durch die Öffnungen 12 von vorne in die Nuten 11 eingeführt. Die Verdickungen 46b gleiten in den Nuten 11 nach unten und die unteren, geschlossenen Enden der Nuten 11 bilden einen Anschlag aus und halten das Sicherheitsgeländer 40.the figure 16 shows a section of the safety railing 40 according to FIG figure 15 in the area of the fastening elements 46 on a vertical beam 41 and a mounting adapter 1. The fastening elements 46 are designed to complement the grooves 11. To fasten the safety railing 40, the fastening elements 46 are inserted through the openings 12 into the grooves 11 from the front. The thickenings 46b slide down in the grooves 11 and the lower, closed ends of the grooves 11 form a stop and hold the safety railing 40.

Die Figur 17 zeigt nochmals das Sicherheitsgeländer 40 der Figur 15 mit zwei Montageadaptern 1. Die Befestigungselemente befinden sich in dieser Darstellung erst auf der Höhe der Öffnungen, sind also noch nicht bis zum Anschlag in die Nuten herunter geführt worden.the figure 17 shows again the safety railing 40 of figure 15 with two mounting adapters 1. In this illustration, the fastening elements are only at the height of the openings, so they have not yet been guided down into the grooves as far as they will go.

Die Figuren 18A-D zeigen verschiedene schematische Ansichten der Schritte zum Aufbau eines Baugerüstes 50 mit Sicherheitsgeländern 40. Die Figur 18A zeigt einen Ausschnitt eines stark vereinfacht dargestellten Baugerüstes 50 mit drei Gerüstetagensegmenten I bis III je Gerüstetage. Jedes Segment I bis III weist Vertikalholme 51 auf, sowie einen Gerüstboden 52. Diese Gerüstboden 52 bilden eine erste und oberste Gerüstetage E1, die noch nicht gesichert ist. Das Anbringen der Gerüstboden 52 erfolgte hier vom Boden aus, also sozusagen von einer letzten gesicherten Etage E0 aus. An die Vertikalholme 41 des linken Segmentes I sind bereits zwei Montageadapter 1 befestigt.the Figures 18A-D Fig. 12 show various schematic views of the steps involved in erecting scaffolding 50 with safety rails 40. Figs Figure 18A shows a detail of a highly simplified scaffolding 50 with three scaffolding level segments I to III per scaffolding level. Each segment I to III has vertical bars 51 and a scaffolding floor 52. This scaffolding floor 52 forms a first and uppermost scaffolding floor E1, which has not yet been secured. The scaffolding deck 52 was attached here from the ground, that is to say from a last secured floor E0, so to speak. Two mounting adapters 1 are already attached to the vertical bars 41 of the left segment I.

In einem nächsten Schritt, siehe Figur 18B , wird jeweils ein Sicherheitsgeländer 40 in zwei benachbarte Montageadapter 1, das heißt in zwei Montageadapter 1, die an benachbarten Vertikalholmen 51 befestigt sind, eingehängt. Dies geschieht von unten aus der letzten gesicherten Etage E0, also dem Boden. Hierzu dient der Handgriff 45, welcher an dem unteren Horizontalholm 43 des Sicherheitsgeländers 40 angebracht ist.In a next step, see Figure 18B , In each case a safety railing 40 is hung in two adjacent mounting adapters 1, that is to say in two mounting adapters 1 which are fastened to adjacent vertical bars 51. This is done from below from the last secured floor E0, i.e. the floor. The handle 45 which is attached to the lower horizontal rail 43 of the safety railing 40 serves for this purpose.

Nach dem Anbringen des/der Sicherheitsgeländer(s) 40 ist das jeweilige Segment I bis III beziehungsweise die Etage E1 gesichert und der Gerüstbauer kann nun im Schutz des Sicherheitsgeländers 40 die oberste Etage E1 fertigstellen. Insbesondere kann nun das eigentliche, dauerhafte Gerüstgeländer 53 angebracht werden, siehe Figur 18C . Weiterhin wird der Gerüstboden 52 für die nächste Gerüstetage E2 von unten an weiteren Vertikalholmen 51 angebracht.After attaching the safety rail(s) 40, the respective segment I to III or the floor E1 is secured and the scaffolder can now complete the top floor E1 protected by the safety rail 40.
