The long side parts (13) are releasably fixable in a vertical position with the aid of locking components (17) in the area of the corner posts of the lower part, and with folded-in cross side parts (29) are located one on the top of the other and parallel to the scaffolding platform.

Description

Die vorliegende Erfindung betrifft einen höhenverstellbaren Gerüsttisch mit rechteckigem Grundriß umfassend ein feststehendes Unterteil mit vier vertikalen Pfosten und ein gegenüber dem Unterteil in der Höhe verstellbares Oberteil mit Längsträgern, Querträgern und einer begehbaren horizontalen Plattform.The present invention relates to a height-adjustable scaffolding table with a rectangular outline comprising a fixed lower part with four vertical posts and a height-adjustable upper part with longitudinal members, cross members and a walkable horizontal platform.

Aufgabe der vorliegenden Erfindung ist es, einen Gerüsttisch für Baustellengerüste zu schaffen, der eine Einheit darstellt, die als Ganzes auf der Baustelle per Kran von einem Einsatzort zum anderen Einsatzort transportiert werden kann, die aber andererseits im Falle des Nichtgebrauchs mit wenigen Handgriffen in eine kompakte Lage zusammengeklappt und platzsparend transportiert werden kann.The object of the present invention is to provide a scaffolding table for construction site scaffolding, which is a unit that can be transported as a whole on the construction site by crane from one place of use to another place of use, but which, on the other hand, can be compacted in a few simple steps when not in use Can be folded and transported to save space.

Bei den bisher verwendeten Arbeitsgerüsten für Baustellen war es üblich, daß das Gerüst zunächst mit relativ hohem Aufwand demontiert und in seine Einzelteile zerlegt wurde, um dann an einem anderen Ort gegebenenfalls auf der gleichen Baustelle wieder aufgebaut zu werden. Hier schafft der erfindungsgemäße Gerüsttisch Abhilfe, da es sich um eine Gerüst-Baueinheit mit Querseitenteilen, Längsseitenteilen und einer in der Höhe verstellbaren begehbaren Arbeitsplattform handelt, die in sich stabil ist. Die zur Stabilisierung des Unterteils des Gerüsttischs dienenden leiterartigen Langsseitenteile können, wenn der Gerüsttisch für den Transport verladen werden soll, abgenommen werden. Die Querseitenteile des Unterteils des Gerüsttischs mit den vertikalen Eckpfosten können dann um eine horizontale Achse in eine Lage geschwenkt werden, in der sie parallel zur Plattform des Gerüsttischs liegen. Die leiterartigen Längsseitenteile können dann vorzugsweise übereinanderliegend und parallel zur Gerüstplattform mit Befestigungselementen am Unterteil des Gerüsttischs befestigt werden, so daß der Gerüsttisch dann kompakt und flach ist und platzsparend transportiert werden kann. Für die lösbare Befestigung am Unterteil des Gerüsttischs können die leiterartigen Längsseitenteile zum Beispiel an den Enden ihrer Längsstreben Laschen mit Ösen aufweisen, so daß eine Befestigung mit Hilfe von Steckbolzen oder dergleichen am Unterteil des Gerüsttischs möglich ist.With the work scaffolding used for construction sites so far, it was common for the scaffold to be dismantled and disassembled into its individual parts at first with a relatively high outlay, in order then to be assembled again at a different location on the same construction site, if necessary. The scaffolding table according to the invention provides a remedy here, since it is a scaffolding unit with transverse side parts, longitudinal side parts and a height-adjustable walk-in work platform which is stable in itself. The ladder-like long side parts used to stabilize the lower part of the scaffolding table can be removed if the scaffolding table is to be loaded for transport. The transverse side parts of the lower part of the scaffolding table with the vertical corner posts can then be pivoted about a horizontal axis into a position in which they lie parallel to the platform of the scaffolding table. The ladder-like longitudinal side parts can then preferably be fastened one above the other and parallel to the scaffolding platform with fastening elements on the lower part of the scaffolding table, so that the scaffolding table is then compact and flat and can be transported in a space-saving manner. For releasable attachment to the lower part of the scaffolding table, the ladder-like longitudinal side parts can have tabs with eyelets, for example at the ends of their longitudinal struts, so that attachment using plug bolts or the like is possible on the lower part of the scaffolding table.

Für die Höhenverstellung des Oberteils des Gerüsttischs werden vorzugsweise mittels einer Kurbel antreibbare Zahnräder verwendet, die in Lochreihen an den vertikalen Tragstützen des Oberteils des Gerüsttischs eingreifen, ähnlich wie bei einem Kurbelgerüstbock.For the height adjustment of the upper part of the scaffolding table, gears that can be driven by means of a crank are preferably used, which engage in rows of holes on the vertical support supports of the upper part of the scaffolding table, similar to a crank scaffold stand.

Das Oberteil kann auch über Gewindespindeln, die mittels einer Kurbel antreibbar sind, höhenverstellbar sein, oder aber es können Lochraster vorgesehen sein und das Oberteil von Hand verstellbar und in verschiedenen Höhenpositionen über Bolzen fixierbar sein. Dabei bedient man sich eines Krans, um das Oberteil anzuheben, während das Unterteil auf dem Boden bleibt.The upper part can also be height-adjustable by means of threaded spindles which can be driven by means of a crank, or hole grids can be provided and the upper part can be adjusted by hand and fixed in different height positions by means of bolts. A crane is used to lift the upper part while the lower part remains on the floor.

Die einschwenkbaren Eckpfosten mit den Querseitenteilen des Unterteils des Gerüsttischs sind vorzugsweise an Gelenklaschen schwenkbar angelenkt, die sich an der Unterseite von Querträgern des Gerüsttischs befinden.The pivotable corner posts with the transverse side parts of the lower part of the scaffolding table are preferably pivotably articulated on articulated brackets which are located on the underside of cross members of the scaffolding table.

Zunächst wird auf die Figuren 1 und 2 Bezug genommen. Der erfindungsgemäße Gerüsttisch 10 hat einen im Prinzip rechteckigen Grundriß und besteht aus einem auf dem Untergrund stehenden Unterteil 11 mit vier vertikalen Pfosten 12 in den Eckbereichen. An den Pfosten 12 eingehängt sind an beiden Längsseiten des Gerüsttischs 10 jeweils ein etwa leiterartiges Längsseitenteil 13, das wie man aus Figur 2 sieht nach Lösen einer Verriegelung vom Unterteil 11 des Gerüsttischs abnehmbar ist. Die Längsseitenteile 13 weisen dazu jeweils an den beiden Enden ihrer oberen Streben 14 und ihrer unteren Streben 15 Laschen 16 auf. In diesen Laschen befinden sich Ösen 17, die in Bolzen, Haken 18 oder dergleichen im Bereich der Eckpfosten 12 einhängbar sind. Die leiterartigen Längsseitenteile 13 haben zwischen den oberen Streben 14 und den unteren Streben 15 verlaufende Querstreben 19 und diagonale Streben 20 zur Aussteifung.First, reference is made to FIGS. 1 and 2. The scaffolding table 10 according to the invention has a basically rectangular outline and consists of a lower part 11 standing on the ground with four vertical posts 12 in the corner areas. Suspended from the posts 12 on both longitudinal sides of the scaffolding table 10 are each approximately ladder-like longitudinal side parts 13 which, as can be seen in FIG. 2, can be removed from the lower part 11 of the scaffolding table after a lock has been released. For this purpose, the longitudinal side parts 13 each have tabs 16 at the two ends of their upper struts 14 and their lower struts 15. In these tabs there are eyelets 17 which can be hung in bolts, hooks 18 or the like in the area of the corner posts 12. The ladder-like longitudinal side parts 13 have transverse struts 19 and diagonal struts 20 for stiffening extending between the upper struts 14 and the lower struts 15.

Anstelle von leiterartigen Längsseitenteilen können auch solche verwendet werden, die zum Beispiel einfach aus einem Kreuz aus zwei verbundenen diagonal verlaufenden Streben bestehen.Instead of ladder-like longitudinal side parts, it is also possible to use those which, for example, simply consist of a cross made of two connected diagonal struts.

Wie dies in Figur 1 gezeigt ist, kann man das als Gerüst dienende Oberteil 21 gegenüber dem feststehenden Unterteil 11 des Gerüsttischs 10 in der Höhe verstellen. Die unterste Position des Oberteils 21 des Gerüsttisches ist in Figur 1 in ausgezogenen Linien dargestellt, eine nach oben gefahrene Position des Oberteils 21 ist in gestrichelten Linien dargestellt. Die Höhenverstellung des Oberteils 21 erfolgt über eine am Unterteil 11 des Gerüsttischs an einer Welle angebrachte Kurbel 22, mittels derer ein auf der Welle 23 angebrachtes sternförmiges Zahnrad 24 angetrieben wird, dessen Zähne in beabstandete Löcher einer Lochreihe an den vertikalen Tragstützen 25 des Oberteils 21 eingreifen. Das Oberteil 21 des Gerüsttisches besteht aus mit den vertikalen Tragstützen 25 verbundenen Längsträgern 26 sowie mehreren zu diesen quer verlaufenden Querträgern 27, die eine Ebene aufspannen, auf die eine Gerüstbelagtafel 28 auflegbar ist. Dies ist aus Figur 2 erkennbar, die das Oberteil 21 des Gerüsttischs ebenfalls in mehreren Höhenpositionen (gestrichelt) zeigt. Figur 2 zeigt ebenfalls, daß die Längsseitenteile 13 vom Unterteil 11 des Gerüsttischs seitlich abnehmbar sind. Dieses Abnehmen erfolgt bei der Demontage des Gerüsttischs für den Transport.As shown in FIG. 1, the height of the upper part 21 serving as a scaffold can be adjusted relative to the fixed lower part 11 of the scaffolding table 10. The lowermost position of the upper part 21 of the scaffolding table is shown in solid lines in FIG. 1, an upwardly moved position of the upper part 21 is shown in dashed lines. The height adjustment of the upper part 21 takes place via a crank 22 attached to a shaft on the lower part 11 of the scaffolding table, by means of which a star-shaped gearwheel 24 attached to the shaft 23 is driven whose teeth engage in spaced holes in a row of holes on the vertical support supports 25 of the upper part 21. The upper part 21 of the scaffolding table consists of longitudinal beams 26 connected to the vertical support supports 25 as well as a plurality of transverse beams 27 extending transversely to these, which span a plane on which a scaffolding covering board 28 can be placed. This can be seen from Figure 2, which also shows the upper part 21 of the scaffolding table in several height positions (dashed lines). Figure 2 also shows that the longitudinal side parts 13 are laterally removable from the lower part 11 of the scaffolding table. This removal takes place when the scaffolding table is removed for transport.

Nach dem Abnehmen der Längsseitenteile 13 können die Querseitenteile 29 durch einwärts schwenken um eine horizontale Gelenkachse 30 in Pfeilrichtung gemäß Figur 1 eingeklappt werden in eine Position, in der sie parallel zu den Längsträgern 26 des Gerüstoberteils liegen. Der Gerüsttisch 10 nimmt dann die raumsparende Lage ein, die in den Figuren 3 und 4 dargestellt ist.After removal of the longitudinal side parts 13, the transverse side parts 29 can be folded in by pivoting inward about a horizontal hinge axis 30 in the direction of the arrow according to FIG. 1 into a position in which they lie parallel to the longitudinal beams 26 of the upper frame part. The scaffolding table 10 then takes up the space-saving position which is shown in FIGS. 3 and 4.

Wie man aus Figur 4 erkennt, liegen die Querseitenteile 29 mit den Eckpfosten 12 parallel zum Oberteil 21 des Gerüsttischs. Die beiden vorher abgenommenen Längsseitenteile 13 des Unterteils 11 des Gerüsttischs werden nun übereinander parallel zu den eingeschwenkten Querseitenteilen 29 gelegt und durch Bolzen 31 oder andere geeignete derartige Befestigungselemente in dieser Lage mit dem Unterteil 11 des Gerüsttischs verbunden. Im zusammengeklappten Zustand gemäß den Figuren 3 und 4 ist somit der Gerüsttisch sehr platzsparend und kompakt, was für den Transport günstig ist. Der Gerüsttisch ist dabei aber so konzipiert, daß er auf der Baustelle ohne demontiert zu werden im zusammengebauten Zustand gemäß den Figuren 1 und 2 mittels eines Krans vom einen Einsatzort zum anderen transportiert werden kann. Zum Beispiel an den Querträgern 27 können Kranösen 32 angebracht sein, so daß man den Gerüsttisch als Ganzes mit einem Kran anheben und transportieren kann.As can be seen from FIG. 4, the transverse side parts 29 with the corner posts 12 lie parallel to the upper part 21 of the scaffolding table. The two previously removed longitudinal side parts 13 of the lower part 11 of the scaffolding table are now placed one above the other parallel to the swung-in transverse side parts 29 and connected in this position to the lower part 11 of the scaffolding table by bolts 31 or other suitable fastening elements of this type. In the folded state according to FIGS. 3 and 4, the scaffolding table is therefore very space-saving and compact, which is favorable for transport. The scaffolding table is designed so that it can be transported from one place of use to another on the construction site without being dismantled in the assembled state according to FIGS. 1 and 2 by means of a crane. For example, crane eyelets 32 can be attached to the cross members 27 so that the scaffolding table can be lifted and transported as a whole with a crane.
