Definitions
- the invention relates to a scaffold frame floor with longitudinal spars on the outside, with cross-connection parts lying on the end faces, connecting the longitudinal spars, to which suspension means are assigned, and with a walkable, liquid-permeable surface support structure that forms the tread.
- Scaffolding is used on building walls, in industrial plants with pipes and other system parts, in other steel structures, on ship walls and the like and for many different purposes. Most of the work only produces water or dirt in small quantities. For such work in which water or dirty water is to drain off, customary scaffold floors with openings in the running and working surface are sufficient. For this purpose, the edges of the holes have been partly bent upwards and partly downwards, so that, on the one hand, a non-slip walking surface is formed and, on the other hand, the resulting liquid can flow downwards in some areas. The user then does not walk in the water. Such training is shown in DE-A-29 16 826. Wooden surfaces are desired for other purposes, such as when the user must sit on the floor, such as painting.
- a metal stand scaffold has become known, the scaffold planks of which have a tread plate which is designed only with elongated hole cutouts for weight reduction and upstanding round cams as anti-slip protection. Letting liquids or especially dusts run off is not the basis for the design of this scaffold plank.
- the invention has for its object to design a scaffold frame floor that can be attached to the usual scaffold support structures in such a way that it is easy to manufacture, great stability and safe use, the resulting abrasive agents from blasting treatments can pass through recesses without deposits form and the stability of the stand and use is also not impaired.
- the thickness of the upper opening-limiting webs of the longitudinal spars and a lattice support structure forming the running surface in order to avoid storage areas for granular blasting material each have only one to four material thicknesses of the base support material sheet and the widening of the longitudinal spars required for carrying and stability reasons and possibly further supporting structure parts in the lower areas with inclined surfaces that allow drainage are extended to the widest extent of the supporting structure parts.
- a scaffold frame floor according to the invention can be formed in a particularly advantageous manner by the longitudinal spar profile having an outer wall that forms an external vertical web, in the area of its lower end a rounded, possibly undulating, connected lower wall that forms a horizontal flange and to the inside of the Frame pointing a rounded transition corner and then has an inclined surface, which is equipped with a vertical connecting leg and the upper vertical parts are connected to the lattice-like support structure to form a load-bearing composite, preferably welded.
- Such a profile can be easily and easily formed with high stability from sheet steel with good and inexpensive manufacturing options. With appropriate needs and usage-related conditions, it can usefully also be designed as a light metal extrusion profile.
- a further development of the invention can provide that the upper end of the outer vertical web is equipped with an inner, inner leg serving for stability and connection by folding inwards.
- a further development of the invention can provide that, when formed from a flat sheet, the joint is formed in the region of the inner leg with aligned end cut parts.
- a further development of the invention can provide that the support structure is formed by vertically standing thin sheet metal parts which are brought into engagement by corresponding cutouts and that these are connected, preferably welded, to the outer frame regions.
- a further development of the invention can provide that the surface support structure is formed by a grating.
- a further development of the invention can provide that hanging claws made of sheet metal are fixedly arranged on the cross-connection parts.
- the scaffold 10 has stems 11, for example with perforated disks 12.
- U-shaped, horizontally extending crossbeams 15, which are open at the top, are fastened to them with the aid of slip-on shoes 13 and wedges 14.
- the hooking claws 17 are fastened to cross-connection parts 21, which are provided at the two ends, in a conventional manner.
- These cross-connection parts 21 can be designed in the form of flat irons, relatively thin, flat sheet metal parts at the top or similar to the longitudinal bars.
- the longitudinal bars 25.1 and 25.2 have a cross section as shown in FIG. 4.
- a sheet profile possibly a tube, is deformed in such a way that a vertical outer wall 26, a horizontal lower wall 27 and an oblique drain inner wall 28 result. These are connected to one another via rounded corners 29.1 and 29.2.
- a wave-shaped bend 32 is formed in the area of the upper end 31 of the inclined inner wall 28 of the drain. This merges with a rounded corner 33 into a vertical inner leg 34. This is connected to the upper end 36 of the vertical outer wall 26 via a folding curve 35. Everything is shown here as if it were pressed out of a pipe. It is preferably bent, folded and folded on a roller mill from a flat sheet, for example from sheet steel.
- the legs which are in alignment with one another can be connected by a weld seam.
- the profile can also be made of light metal in a similar cross-sectional shape in a strand deformation process.
- the upper fastening sections 40 are connected on the inside to the outer frame plate 41, for example by means of a continuous weld seam 42 or corresponding weld seam sections.
- the frame plate 41 of the grating 38 is the same height or slightly higher than the dimension 44 of the fastening section 40 and protrudes slightly upwards over the fastening section 40, so that there is a good weld at 42.
- One of two such longitudinal spars 25.1 u. 25.2 and two cross-connection parts 21 formed all around frame is filled with a conventional grating with inner, vertically arranged, matching punched out crossing support plates 45.
- the frame sheets - as can be seen in FIG. 3 - are made of somewhat stronger steel sheet than the mesh-limiting support sheets 45.
- the support sheets can also have a lower height in one direction or be replaced by suitably machined bars. It is important that large mesh holes are formed, which are supported by narrow-walled ribs that bear the load of the people using them, so that there are no horizontal surfaces on the scaffold floor that lead to deposits of abrasive components in the cleaning work. Also in the edge area, the support structure is so thin-walled and too knife-like at the top that no grain accumulations can remain.
- the thickness of the upper opening-limiting webs which are formed on the one hand in the area of the longitudinal spars with the upper end 36 of the vertical outer wall 26 and the vertical inner leg 34 and the outer frame plate 41 of the grating 38 and on the other hand formed by the support plates 45 in the area of the grating support structure forming the tread are - as can be seen - only one to four material thicknesses of the base material sheet in order to avoid storage areas for granular blasting material.
- the widening of the longitudinal spars required for load-bearing and stability reasons and possibly further supporting structure parts in the lower areas are additionally led to the widest expansion of the supporting structure parts, such as the horizontal lower wall 27, with inclined surfaces that allow drainage, such as the inclined inner wall drain 28.
- the cross-connection parts 21 can be formed as sufficiently load-bearing, thick flat sheets. However, you can also have a profile shape that can be approximated to that of the longitudinal spars, because it is important that no horizontal surfaces are provided for deposits and that inclined surfaces lead to the horizontally wider material collections of the profiles, which allow material to flow off. Longitudinal beads or transverse embossing can also be introduced for reinforcement in relatively thin-walled metal sheets, despite the large scaffold frame floor To ensure the stability and smooth running of components of the work.
- the hanging devices can also be adapted to the respective scaffolding system.
- the scaffold frame floors can also be made wider or combined, depending on which scaffold structures are suitable for use.
- a scaffold frame floor (20) has longitudinal spars (25.1, 25.2) and cross-connection parts.
- a grating (38) is permanently installed between the fastening sections (40). This has outer frame plates (41) and inner, intersecting support plates (45).
- the profile of the longitudinal spars (25.1, 25.2) has a vertical outer wall, a horizontal lower wall and an inclined drain inner wall (28) which merges into the vertical inner leg with a wavy bend. The grate is attached to this.
Abstract
Description
Die Erfindung betrifft einen Gerüstrahmenboden mit außen liegenden Längsholmen, mit an den Stirnseiten liegenden, die Längsholme verbindenden Querverbindungsteilen, denen Einhängemittel zugeordnet sind und mit einer die Lauffläche bildenden, begehbaren, Flüssigkeit durchlassenden Flächen-Tragstruktur.The invention relates to a scaffold frame floor with longitudinal spars on the outside, with cross-connection parts lying on the end faces, connecting the longitudinal spars, to which suspension means are assigned, and with a walkable, liquid-permeable surface support structure that forms the tread.
Gerüste werden an Gebäudewänden, bei Industrieanlagen mit Rohren und sonstigen Anlageteilen, bei sonstigen Stahlkonstruktionen, an Schiffswänden und dgl. und für vielerlei verschiedene Zwecke benutzt. Bei den allermeisten Arbeiten fällt entweder nur Wasser oder Schmutz in geringen Mengen an. Für solche Arbeiten, bei denen Wasser oder verschmutztes Wasser abfließen soll, reichen übliche Gerüstböden mit Durchbrechungen in der Lauf- und Arbeitsfläche aus. Dazu hat man die Ränder der Löcher zum Teil nach oben und zum Teil nach unten abgebogen, so daß einerseits eine rutschsichere Gehfläche gebildet wird und andererseits in Teilbereichen die anfallende Flüssigkeit nach unten abfließen kann. Der Benutzer läuft dann nicht im Wasser. Eine derartige Ausbildung ist in DE-A-29 16 826 dargestellt. Für andere Zwecke wünscht man Oberflächen aus Holz, beispielsweise wenn der Benutzer auf dem Boden sitzen muß, wie bei Anstricharbeiten.Scaffolding is used on building walls, in industrial plants with pipes and other system parts, in other steel structures, on ship walls and the like and for many different purposes. Most of the work only produces water or dirt in small quantities. For such work in which water or dirty water is to drain off, customary scaffold floors with openings in the running and working surface are sufficient. For this purpose, the edges of the holes have been partly bent upwards and partly downwards, so that, on the one hand, a non-slip walking surface is formed and, on the other hand, the resulting liquid can flow downwards in some areas. The user then does not walk in the water. Such training is shown in DE-A-29 16 826. Wooden surfaces are desired for other purposes, such as when the user must sit on the floor, such as painting.
Zum technologischen Hintergrund ist gemäß DE-U-91 12 423 ein Metallstandgerüst bekannt geworden, dessen Gerüstbohlen ein Trittblech aufweisen, welches nur mit Langloch-Aussparungen zur Gewichtserleichterung und nach oben stehenden Rundnocken als Gleitschutz gestaltet ist. Das Abfließenlassen von Flüssigkeiten oder vor allem Stäuben ist nicht Gestaltungsbasis dieser Gerüstbohle.For the technological background, according to DE-U-91 12 423, a metal stand scaffold has become known, the scaffold planks of which have a tread plate which is designed only with elongated hole cutouts for weight reduction and upstanding round cams as anti-slip protection. Letting liquids or especially dusts run off is not the basis for the design of this scaffold plank.
Ferner ist zum technologischen Hintergrund gemäß DE-A-15 34 866 eine Plattform bekannt geworden, bei der eine gewöhnliche Gitterstruktur verwendet ist. Für die Verbesserung der Tragverhältnisse in den Randbereichen der Plattform unter Berücksichtigung von Abfließmöglichkeiten sind daraus jedoch keine Gesichtspunkte zu entnehmen.Furthermore, for the technological background according to DE-A-15 34 866, a platform has become known in which an ordinary lattice structure is used. However, no considerations can be derived from this for improving the load-bearing conditions in the edge areas of the platform, taking drainage options into account.
In zunehmendem Maße wird es erforderlich, Fassaden, Anlageteile und dgl. mit Strahlgebläsen zu reinigen bzw. Oberfläche auf ähnliche Weise aufzubereiten. Dann fallen große Mengen von zumeist harten Abriebshilfsmittel-Körnern an. Bei Feuchtigkeit können diese verkleben. Die üblichen Durchbrechungen in den Lauf- und Arbeitsflächen können dann verstopfen. Außerdem lagert sich entsprechendes Material in Teilbereichen, in denen Horizontalflächen gebildet sind, ab. Für solche Zwecke geeignete Laufbodenelemente für Gerüste fehlen.It is becoming increasingly necessary to clean facades, system parts and the like using jet blowers or to prepare the surface in a similar manner. Then large amounts of mostly hard abrasion aid grains are obtained. When damp, they can stick together. The usual openings in the running and work surfaces can then become blocked. Corresponding material is also deposited in partial areas in which horizontal surfaces are formed. Suitable floor elements for scaffolding are missing for such purposes.
Der Erfindung liegt die Aufgabe zugrunde, einen Gerüstrahmenboden, der an den üblichen Gerüst-Tragstrukturen befestigt werden kann, derart auszugestalten, daß er bei leichter Herstellbarkeit, großer Stabilität und sicherer Benutzung die anfallenden abrasiven Mittel von Strahlbehandlungen durch Ausnehmungen treten läßt, ohne daß sich Ablagerungen bilden und wobei außerdem die Stand- und Benutzungssicherheit nicht beeinträchtigt ist.The invention has for its object to design a scaffold frame floor that can be attached to the usual scaffold support structures in such a way that it is easy to manufacture, great stability and safe use, the resulting abrasive agents from blasting treatments can pass through recesses without deposits form and the stability of the stand and use is also not impaired.
Erfindungsgemäß ist vorgesehen, daß die Dicke der oberen Öffnungsbegrenzungsstege der Längsholme und einer die Lauffläche bildenden Gittertragstruktur zwecks Vermeidung von Ablageflächen für körniges Strahlgut nur jeweils ein bis vier Materialstärken des Grundtragmaterial-Bleches aufweist und die aus Trag- und Stabilitätsgründen erforderlichen Verbreiterungen der Längsholme und ggf. weitere Tragstruktur-Teile in unteren Bereichen mit das Abfließen ermöglichenden Schrägflächen zur breitesten Ausdehnung der Tragstruktur-Teile geführt sind.According to the invention, it is provided that the thickness of the upper opening-limiting webs of the longitudinal spars and a lattice support structure forming the running surface in order to avoid storage areas for granular blasting material each have only one to four material thicknesses of the base support material sheet and the widening of the longitudinal spars required for carrying and stability reasons and possibly further supporting structure parts in the lower areas with inclined surfaces that allow drainage are extended to the widest extent of the supporting structure parts.
Dadurch daß man nur dünne, schmale Stege auch im Randbereich hat und dazwischen entsprechend große Öffnungen, kann nichts liegenbleiben. Die in die Breite sich erstreckenden Anteile der erforderlichen Querschnitte in tiefer liegenden Bereichen werden dadurch sinnvoll gestaltet, daß es Schrägflächen gibt, von denen die Staub- und Abriebkörner ggf. zusammen mit Flüssigkeit abfließen können.Because there are only thin, narrow webs in the edge area and large openings between them, nothing can remain. The proportions of the required cross sections in the lower lying areas, which extend in the width, are sensibly designed by the fact that there are inclined surfaces from which the dust and abrasive grains can possibly flow off together with liquid.
Ein erfindungsgemäßer Gerüstrahmenboden kann in besonders vorteilhafter Weise gebildet werden, indem das Längsholm-Profil eine außen liegende, einen vertikalen Steg bildende Außenwand, im Bereich von deren unterem Ende eine gerundet, ggf. wellenförmig angeschlossene, einen Horizontal-Flansch bildende Unterwand und zum Innern des Rahmens weisend eine gerundete Übergangsecke sowie sich daran anschließend eine Schrägfläche aufweist, die mit einem vertikalen Verbindungsschenkel ausgestattet ist und wobei die oberen Vertikalteile mit der gitterartigen Tragstruktur einen mittragenden Verbund bildend verbunden, vorzugsweise verschweißt, sind. Ein solches Profil läßt sich bei guten und preiswerten Herstellungsmöglichkeiten gut und einfach mit hoher Stabilität aus Stahlblech formen. Bei entsprechenden Bedürfnissen und benutzungsmäßigen Gegebenheiten kann es sinnvollerweise auch als Leichtmetall-Strangform-Profil ausgebildet sein.A scaffold frame floor according to the invention can be formed in a particularly advantageous manner by the longitudinal spar profile having an outer wall that forms an external vertical web, in the area of its lower end a rounded, possibly undulating, connected lower wall that forms a horizontal flange and to the inside of the Frame pointing a rounded transition corner and then has an inclined surface, which is equipped with a vertical connecting leg and the upper vertical parts are connected to the lattice-like support structure to form a load-bearing composite, preferably welded. Such a profile can be easily and easily formed with high stability from sheet steel with good and inexpensive manufacturing options. With appropriate needs and usage-related conditions, it can usefully also be designed as a light metal extrusion profile.
Eine Weiterbildung der Erfindung kann vorsehen, daß das obere Ende des äußeren Vertikalsteges durch Faltung nach innen mit einem inneren, der Stabilität und dem Anschluß dienenden vertikalen Innenschenkel ausgestattet ist.A further development of the invention can provide that the upper end of the outer vertical web is equipped with an inner, inner leg serving for stability and connection by folding inwards.
Eine Weiterbildung der Erfindung kann vorsehen, daß bei Formung aus einem Flachblech der Stoß im Bereich des Innenschenkels mit fluchtend übereinander liegenden Endschnitteilen gebildet ist.A further development of the invention can provide that, when formed from a flat sheet, the joint is formed in the region of the inner leg with aligned end cut parts.
Eine Weiterbildung der Erfindung kann vorsehen, daß die Tragstruktur von vertikal stehenden, in den Kreuzungspunkten durch entsprechende Ausschnitte zum Eingriff gebrachten dünnen Blechteilen gebildet ist und diese mit den äußeren Rahmenbereichen verbunden, vorzugsweise verschweißt, sind.A further development of the invention can provide that the support structure is formed by vertically standing thin sheet metal parts which are brought into engagement by corresponding cutouts and that these are connected, preferably welded, to the outer frame regions.
Eine Weiterbildung der Erfindung kann vorsehen, daß die Flächen-Tragstruktur von einen Gitterrost gebildet ist.A further development of the invention can provide that the surface support structure is formed by a grating.
Eine Weiterbildung der Erfindung kann vorsehen, daß an den Querverbindungsteilen aus Blech geformte Einhängeklauen fest angeordnet sind.A further development of the invention can provide that hanging claws made of sheet metal are fixedly arranged on the cross-connection parts.
Weitere Einzelheiten, Vorteile, Merkmale und Gesichtspunkte der Erfindung ergeben sich auch aus dem anhand der Zeichnungen abgehandelten nachfolgenden Beschreibungsteil.Further details, advantages, features and aspects of the invention also emerge from the following description part dealt with on the basis of the drawings.

Das Gerüst 10 hat Stiele 11, beispielsweise mit Lochscheiben 12. An diesen sind mit Hilfe von Aufsteckschuhen 13 und Keilen 14 nach oben offene U-förmige, horizontal verlaufende Quer-Tragriegel 15 befestigt. In diese sind mit Hilfe der Einhängeklauen 17 erfindungsgemäße Gerüstrahmenböden 20 eingehängt. Die Einhängeklauen 17 sind an Querverbindungsteilen 21, die an den beiden Enden vorgesehen sind, in üblicher Weise befestigt. Diese Querverbindungsteile 21 können in Form von Flacheisen, oben relativ dünnen, flachen Blechteilen oder ähnlich wie die Längsholme gestaltet sein.The
Die Längsholme 25.1 und 25.2 haben einen Querschnitt wie er in Fig. 4 dargestellt ist. Dabei ist ein Blechprofil, ggf. ein Rohr, derart verformt, daß sich eine vertikale Außenwand 26, eine horizontale Unterwand 27 und eine schräge Ablauf-Innenwand 28 ergeben. Diese sind über gerundete Ecken 29.1 und 29.2 miteinander verbunden. Im Bereich des oberen Endes 31 der schrägen Ablauf-Innenwand 28 ist eine wellenförmige Abbiegung 32 gebildet. Diese geht mit einer gerundeten Ecke 33 in einen vertikalen Innenschenkel 34 über. Dieser ist über eine Faltungsrundung 35 mit dem oberen Ende 36 der vertikalen Außenwand 26 verbunden. Hier ist alles so dargestellt, als wenn es aus einem Rohr gedrückt ist. Es wird vorzugsweise auf einer Rollenstraße aus einem Flachblech, beispielsweise aus Stahlblech abgebogen, gefalzt und gekantet. An einer passenden Stelle, vorzugsweise in der Vertikalmitte des vertikalen Innenschenkels 34, können die sich fluchtend stoßenden Schenkel durch eine Schweißnaht verbunden sein. Das Profil kann auch aus Leichtmetall in ähnlicher Querschnittsform in einem Strang-Verformungsverfahren hergestellt sein.The longitudinal bars 25.1 and 25.2 have a cross section as shown in FIG. 4. A sheet profile, possibly a tube, is deformed in such a way that a vertical
Wie Fig. 3 und 4 veranschaulichen, sind die oberen Befestigungs-Abschnitte 40 innen mit dem äußeren Rahmenblech 41, beispielsweise durch eine durchlaufende Schweißnaht 42 oder entsprechende Schweißnahtabschnitte, verbunden. Das Rahmenblech 41 des Gitterrostes 38 ist gleich hoch oder etwas höher als das Maß 44 des Befestigungs-Abschnittes 40 und steht etwas nach oben über den Befestigungs-Abschnitt 40 über, so daß sich eine gute Verschweißung bei 42 ergibt.3 and 4 illustrate, the
Ein aus zwei solcher Längsholme 25.1 u. 25.2 und zwei Querverbindungsteilen 21 gebildeter ringsum angeordneter Rahmen ist mit einem üblichen Gitterrost mit inneren, vertikal angeordneten, sich passend ausgestanzt kreuzenden Tragblechen 45 ausgefüllt.One of two such longitudinal spars 25.1 u. 25.2 and two
Dabei sind die Rahmenbleche - wie aus Fig. 3 ersichtlich - aus etwas stärkerem Stahlblech gefertigt als die maschenbegrenzenden Tragbleche 45. Auch können die Tragbleche in einer Richtung eine geringere Höhe haben oder von passend bearbeiteten Stäben ersetzt werden. Wichtig ist, daß große Maschenlöcher gebildet sind, die von schmalwandigen, die Last der benutzenden Personen tragenden Rippen gestützt werden, so daß sich auf dem Gerüstrahmenboden keine Horizontalflächen ergeben, die zu Ablagerungen von abrasiven Bestandteilen der Reinigungsarbeiten führen. Auch im Randbereich ist die Stützkonstruktion so dünnwandig und nach oben zu messerartig gestaltet, daß keine Kornansammlungen liegen bleiben können.The frame sheets - as can be seen in FIG. 3 - are made of somewhat stronger steel sheet than the mesh-limiting
Die Dicke der oberen Öffnungsbegrenzungsstege, die einerseits im Bereich der Längsholme mit dem oberen Ende 36 der vertikalen Außenwand 26 und dem vertikalen Innenschenkel 34 und dem äußeren Rahmenblech 41 des Gitterrostes 38 gebildet sind und andererseits im Bereich der die Lauffläche bildenden Gittertragstruktur von den Tragblechen 45 gebildet sind, beträgt - wie ersichtlich - zwecks Vermeidung von Ablageflächen für körniges Strahlgut nur jeweils ein bis vier Materialstärken des Grundtragmaterial-Bleches. Die aus Trag- und Stabilitätsgründen erforderlichen Verbreiterungen der Längsholme und ggf. weitere Tragstrukturteile in unteren Bereichen sind zusätzlich mit das Abfließen ermöglichenden Schrägflächen, wie der schrägen Ablauf-Innenwand 28, zur breitesten Ausdehnung der Tragstruktur-Teile, wie der horizontalen Unterwand 27, geführt.The thickness of the upper opening-limiting webs, which are formed on the one hand in the area of the longitudinal spars with the
Die Querverbindungsteile 21 können als ausreichend tragfähige, dicke Flachbleche gebildet sein. Sie können jedoch auch eine Profilgestalt haben, die der der Längsholme angenähert werden kann, denn es kommt darauf an, daß keine Horizontalflächen für Ablagerungen vorgesehen sind und daß zu den in der Horizontalen breiteren Materialansammlungen der Profile Schrägflächen führen, die heruntergelangendes Material abfließen lassen. Auch kann man zur Verstärkung in relativ dünnwandigen Blechen Längssicken oder Querprägungen einbringen, um den Gerüstrahmenboden im ganzen trotz großer Stabilität und gutem Ablauf von anfallenden Bestandteilen der Arbeit stabil zu gestalten. Auch die Einhängeeinrichtungen können dem jeweiligen Gerüstsystem angepaßt sein. Man kann die Gerüstrahmenböden auch breiter oder untereinander vereinigt ausführen, je nachdem welche Gerüstkonstruktionen für die Verwendung in Betracht kommen.The

characterised in that, for the purpose of preventing deposition surfaces for granular abrasion-blasting material, the thickness of the upper, opening-delimiting ribs of the longitudinal rails (25.1, 25.2), and of a supporting grid structure (38) which forms the bearing surface is only one to four times the thickness of the material of the sheet metal of the basic supporting material, and the lower regions of the widened sections (27) of the longitudinal rails (25.1, 25.2) which are necessary for reasons of support and stability, and optionally of other parts of the supporting structure, are led towards the widest extent of the parts of the supporting structure by sloping faces (28) which permit run-off. - A scaffolding frame floor according to claim 1,
characterised in that the longitudinal rail section comprises an externally situated outer wall (26) forming a vertical rib, a radiused bottom wall (27) in the region of the lower end of the outer wall, which bottom wall forms a horizontal flange and is optionally attached via a corrugation, and a radiused transition corner which points towards the inside of the frame, and comprises a sloping face (28) which is attached to the transition corner and which is provided with a vertical joining limb (34), and wherein the upper vertical parts are joined, preferably by welding, to the grid-like supporting structure (38) forming a jointly supporting composite. - A scaffolding frame floor according to claim 1 or 2,
characterised in that the upper end of the outer vertical rib is provided, by folding it inwards, with an inside, vertical inner limb (34) which serves for stability and attachment. - A scaffolding frame floor according to one or more of the preceding claims,
characterised in that when it is formed from a flat metal sheet the folded joint in the region of the inner limb (34) is formed with its end section parts aligned one on top of the other. - A scaffolding frame floor according to one or more of the preceding claims,
characterised in that the supporting structure is formed from thin, vertical sheet metal parts (45) which are brought into engagement at their points of intersection by corresponding cut-outs and which are joined, preferably by welding, to the outer frame regions. - A scaffolding frame floor according to one or more of the preceding claims,
characterised in that the planar supporting structure is formed from a grating (38). - A scaffolding frame floor according to one or more of the preceding claims,
characterised in that suspension claws (17) formed from sheet metal are fixedly disposed on the transverse connecting parts (21).
