The base (70) of groove lies beneath the level of the supporting surface (41) for the board. The base of the groove can also be wider than the minimum separation between the end face of the board and the groove wall (42). <IMAGE>

Description

Die Erfindung betrifft einen Gerüstboden mit einer aus Profilteilen zusammengesetzten rahmenartigen Stützausbildung, die Längsholme enthält, welche aus Abschnitten von Leichtmetall-Strang-Preß-Profilteilen gebildet sind und wobei das Profil eine vertikale Innenwand, eine vertikale Außenwand, eine horizontale Unterwand, eine Oberwand sowie weitere Auflage-, Stütz- und Verstärkungsmittel aufweist, unter denen eine untere Zentrierrippe und ein oberer Stapelzentrierungsfalz vorgesehen sind und wobei auf der Stützausbildung eine die Lauffläche des Gerüstbodens bildende Platte befestigt ist.The invention relates to a scaffolding floor with a frame-like support structure composed of profile parts, which contains longitudinal spars, which are formed from sections of light metal extruded profile parts and wherein the profile has a vertical inner wall, a vertical outer wall, a horizontal lower wall, an upper wall and others Has support, support and reinforcing means, under which a lower centering rib and an upper stacking centering fold are provided and wherein a plate forming the running surface of the scaffold floor is fastened to the support formation.

Es gibt eine große Zahl von Gerüstböden, darunter solche, die eine Rahmenkonstruktion haben, auf der eine Platte befestigt ist.There are a large number of scaffold floors, including those that have a frame structure on which a plate is attached.

Für solche Platten hat sich aus vielerlei Gründen nach wie vor Holz besonders bewährt. Vor allem auch bei Schichthölzern ist der Rand durch Wasser und sonstige Flüssigkeiten, stauende Nässe und mangelnde Luftzirkulation stark beeinträchtigt. Das gilt selbst für die Gerüstrahmenboden, wie sie beispielsweise in DE-A 40 11 624 gezeigt sind.Wood has proven particularly useful for such panels for a variety of reasons. Especially with laminated timber, the edge is severely affected by water and other liquids, accumulating moisture and a lack of air circulation. This even applies to the scaffold frame floor, as shown for example in DE-A 40 11 624.

Zum Kantenschutz hat man auch übergreifend Profilteile der Leichmetall-Längsholme, wie z.B. bei der Konstruktion nach DE-A 35 39 507, verwendet. Auch damit hat man keine besonderen langfristigen Erfolge erzielen können, weil entweder der Kantenschutz schlecht oder der Kantenschutz gut und die Belüftung schlecht waren.For edge protection, there are also overlapping profile parts of the light metal side rails, e.g. used in the construction according to DE-A 35 39 507. Even with this one could not achieve any particular long-term success because either the edge protection was bad or the edge protection was good and the ventilation was bad.

Der Erfindung liegt die Aufgabe zugrunde, für einen Gerüstboden mit den eingangs genannten Merkmalen eine Lösung vorzuschlagen, bei der durch sinnvolle Gestaltung des Holmprofiles Verbesserungen bezüglich des Kantenschutzes, der Rutschsicherheit für die Benutzer und vor allem der Belüftung und Flüssigkeitsabführung gegeben sind.The invention has for its object to propose a solution for a scaffolding floor with the features mentioned, in which improvements in edge protection, slip resistance for the user and, above all, ventilation and liquid drainage are given by sensible design of the spar profile.

Erfindungsgemäß ist vorgesehen, daß zwischen einer Verschiebe-Begrenzungs-Rippe und deren Falzwand einerseits und dem Rand der Platte andererseits eine Entwässerungs- und Belüftungs-Nut gebildet ist, deren Nutgrund unterhalb der Auflagefläche der Platte liegt.According to the invention, a drainage and ventilation groove is formed between a displacement-limiting rib and its rebate wall on the one hand and the edge of the plate, the groove base of which lies below the contact surface of the plate.

Dadurch daß neben dem Rand der Platte ein ausreichend großer Belüftungsraum mit einer tiefer liegenden Rinne gebildet ist, kann Wasser stets gut abfließen und selbst unter dem Rand kann Feuchtigkeit aus dem Bereich der Auflageflächen ausgetrieben werden. Kapillarwirkung durch breite Auflageflächen und/oder enge Auflagespalten kann sich nicht einstellen, so daß die übliche Feinde von Holz und Schichtholz keinen Angriff finden.Because a sufficiently large ventilation space is formed next to the edge of the plate with a channel lying deeper, water can always drain off well and even under the edge moisture can be expelled from the area of the contact surfaces. Capillary action due to wide contact surfaces and / or narrow contact gaps cannot occur, so that the usual enemies of wood and plywood are not attacked.

Ferner kann vorgesehen sein, daß der Nutgrund breiter als der kleinste Abstand zwischen Stirnfläche der Platte und Falzwand ist.
Ferner kann vorgesehen sein, daß die Auflagefläche für den Rand der Platte mit Stütz- und Rutschsicherungsrippen und dazwischen gebildeten Belüftungsnuten gestaltet ist.
Ferner kann vorgesehen sein, daß die oberen Trittflächen der Längsholme im Abstand oberhalb der Lauffläche der Platte liegen.
Ferner kann vorgesehen sein, daß die obere Trittfläche der Verschiebebegrenzungs-Rippe mit flachen Rippen und dazwischen liegenden Schmutz- und Wasserrinnen gestaltet ist.
Ferner kann vorgesehen sein, daß das gesamte Profil der Längsholme mit im wesentlichen gleicher Wandstärke mit Ausnahme der Zentrier-Rippe und der Verschiebebegrenzungs-Rippe gebildet ist.
Ferner kann vorgesehen sein, daß das Profil im wesentlichen einen im Querschnitt rechteckigen glattwandigen Hohlraum begrenzt, welcher im Bereich neben der Platte eine im wesentlichen rechteckförmige schmalere Fortsetzung nach oben hat.
Der Rahmen ist stabil ausgeführt, so daß auch nach längerem Gebrauch bei Nachlassen der Tragfähigkeit der Platte Unfallgefahren vorgebeugt ist.
Durch das Tieferlegen des Unterbodens der Rinne und ggf. besonderer Neigung oder Ausgestaltung kann die Flüssigkeit besser abgeführt werden.It can also be provided that the groove base is wider than the smallest distance between the end face of the plate and the rebate wall.
Furthermore, it can be provided that the bearing surface for the edge of the plate is designed with support and anti-slip ribs and ventilation grooves formed between them.
It can also be provided that the upper treads of the longitudinal spars are spaced above the running surface of the plate.
Furthermore, it can be provided that the upper tread of the displacement limiting rib is designed with flat ribs and dirt and water channels lying between them.
It can further be provided that the entire profile of the longitudinal spars is formed with essentially the same wall thickness, with the exception of the centering rib and the displacement-limiting rib.
Furthermore, it can be provided that the profile essentially delimits a smooth-walled cavity with a rectangular cross section, which in the area next to the plate has an essentially rectangular, narrow continuation upwards.
The frame is sturdy, so that even after prolonged use, if the load-bearing capacity of the plate decreases, the risk of accidents is prevented.
By lowering the underbody of the channel and, if necessary, having a special inclination or configuration, the liquid can be better drained off.

Im übrigen ist die bekannte Stapeleigenschaft erhalten und durch sinnvoll stabile Ausbildung im Bereich der Stapelrippe und eines starken laufflächenartigen Randes ist der Gerüstrahmenboden sinnvoll gestaltet.In addition, the known stacking property is retained, and the scaffold frame base is designed in a sensible manner through a sensibly stable design in the area of the stacking rib and a strong tread-like edge.

Weitere Gesichtspunkte, Vorteile und Merkmale der Erfindung ergeben sich auch aus den weiteren Ansprüchen und dem nachfolgenden, anhand der Zeichnungen abgehandelten Beschreibungsteil.Further aspects, advantages and features of the invention also result from the further claims and the following description part, which is dealt with on the basis of the drawings.

In Fig. 1 ist von einem Gerüst nur ein kleiner Teil dargestellt. Dabei tragen die Stiele 20 in einem dem Rastermaß des Gerüstsystems entsprechenden Abstand voneinander an sich bekannte Lochscheiben 21. Zwischen den Stielen 20 ist an den Lochscheiben 21 mit Hilfe von Anschlußköpfen 30 ein Tragriegel 22 befestigt. Der Tragriegel 22 ist als nach oben offenes U-Profil gestaltet. Die oberen Enden der vertikalen Schenkel 27.1 und 27.2 des Tragriegels 22 sind als Auflageränder 23 für die Auflagehaken 25 des Gerüstbodens 26 gestaltet. Die Anschlußköpfe 30 sind in bekannter Weise mit Schlitzen gestaltet und auf die Lochscheiben 21 gesteckt und daran mit Keilen 34 gesichert. In dieser oder ähnlicher Art sind viele Gerüstetagen in einem Gerüst realisiert. Dieser Ausschnitt ist nur dargestellt, um zu veranschaulichen, wie die erfindungsgemäßen Längsholm-Profile mit ihren Gestaltungen im ganzen Gerüst angeordnet sind.In Fig. 1 only a small part of a scaffold is shown. In this case, the stems 20 carry perforated disks 21, which are known per se, according to the spacing of the scaffolding system. Between the stems 20, a support bolt 22 is fastened to the perforated disks 21 with the aid of connecting heads 30. The support bar 22 is designed as an upwardly open U-profile. The upper ends of the vertical legs 27.1 and 27.2 of the support bar 22 are designed as support edges 23 for the support hooks 25 of the scaffold floor 26. The connection heads 30 are designed in a known manner with slots and plugged onto the perforated disks 21 and secured to them with wedges 34. In this or a similar way, many scaffolding days are realized in one scaffold. This section is only shown to illustrate how the longitudinal beam profiles according to the invention are arranged with their designs in the entire framework.

Wie die Fig.1 und 2 zeigen, hat der hier als Beispiel gewählte Gerüstboden 26 drei Auflagehaken 25 an jeder Stirnseite, die in üblicher Weise an einer Endkappe 29 befestigt sind. Diese ist in üblicher Weise mit Nieten 28, wie in Fig. 5 angedeutet, befestigt.As shown in FIGS. 1 and 2, the scaffold floor 26 selected here as an example has three support hooks 25 on each end face, which are fastened to an end cap 29 in the usual way. This is fastened in the usual way with rivets 28, as indicated in FIG. 5.

Die Längsholme 38.1 und 38.2 sind durch wenigstens eine, beispielsweise zwischen sie geschweißte, Queraussteifung 36 verbunden. Eine Platte 45 aus geeignet hergestelltem Sperrholz oder sonstigem Material hat einen Rand 43. Dieser ist mit Nieten 47 in geeignetem Abstand auf dem jeweiligen Längsholm 38.1 bzw. 38.2 befestigt. In allen Zeichnungen, außer den Fig. 1 und 2 ist der Übersichtlichkeit halber nur der jeweils linke Längsholm 38.1 im einzelnen dargestellt. Der rechte Längsholm 38.2 ist in gleicher Weise ausgebildet, jedoch spiegelbildlich angeordnet und entsprechend befestigt.The longitudinal bars 38.1 and 38.2 are connected by at least one transverse bracing 36, for example welded between them. A plate 45 made of suitably produced plywood or other material has an edge 43. This is fastened with rivets 47 at a suitable distance on the respective longitudinal spar 38.1 or 38.2. In all of the drawings, except for FIGS. 1 and 2, only the left longitudinal spar 38.1 is shown in detail for the sake of clarity. The right longitudinal spar 38.2 is designed in the same way, but is arranged in mirror image and fastened accordingly.

Die Längsholme 38.1 und 38.2 ergeben zusammen mit den Endkappen 29 und den Queraussteifungen 36 einen stabilen Rahmen, der die Stützausbildung 37 des Gerüstbodens 26 bildet.The longitudinal bars 38.1 and 38.2 together with the end caps 29 and the transverse stiffeners 36 form a stable frame which forms the support formation 37 of the scaffold floor 26.

Er hat, wie die Fig. 3 bis 5 zeigen, Auflageflächen 41, die sich etwa über die Hälfte der Außenbreite 145 der Profile 100 der Längsholme 38.1 bis 38.4 erstrecken und jeweils bis etwa zur Mitte reichen.As shown in FIGS. 3 to 5, it has contact surfaces 41 which extend approximately over half the outer width 145 of the profiles 100 of the longitudinal spars 38.1 to 38.4 and each extend to approximately the middle.

Auflageflächen 41 sind zur guten Haftung mit Stütz- und Rutschsicherungsrippen 48 und dazwischen gebildeten Belüftungsnuten 49 (Fig. 4) gestaltet, so daß die Platte 45 auch von unten gut belüftet befestigt werden kann. Die Platte 45 kann aus kochfest verleimtem Sperrholz mit Antirutschschicht oder einem sonstigen bei Gerüsten üblichen Material gebildet sein. Sie hat als Oberfläche eine Lauffläche 46 des Gerüstbodens 26. Mit Hilfe von in geeigneten Abständen angeordneten Nieten 47, beispielsweise Hohlnieten oder Blindnieten, ist der Rand 43 an den Längsholmen 38.1 bis 38.4 fest genietet.Support surfaces 41 are designed for good adhesion with support and anti-slip ribs 48 and ventilation grooves 49 (FIG. 4) formed between them, so that the plate 45 can also be fastened in a well-ventilated manner. The plate 45 can be formed from heat-resistant glued plywood with an anti-slip layer or another material that is common in scaffolding. It has a running surface 46 of the scaffolding floor 26 as the surface. With the aid of rivets 47 arranged at suitable intervals, for example hollow rivets or blind rivets, the edge 43 is riveted to the longitudinal spars 38.1 to 38.4.

Das Profil 100 jedes Längsholmes 38.1 bis 38.4 ist ein Leichtmetall-Strang-Preß-Profil, das an den Enden 39.1 und 39.2 abgeschnitten ist. In die Enden sind in üblicher Weise die abgewinkelten Laschen 32 eingenietet.The profile 100 of each longitudinal bar 38.1 to 38.4 is a light metal extrusion profile which is cut off at the ends 39.1 and 39.2. The angled tabs 32 are riveted into the ends in a conventional manner.

Das Profil 100 hat eine Unterwand 105, eine Oberwand 106, eine Innenwand 107 und eine Außenwand 108. In der unteren äußeren Ecke 109 ist unter der Unterwand 105 nach unten vorstehend eine bekannte, im wesentlichen halbzylinderförmige Zentrier-Rippe 110 ausgebildet. Sie dient der Verstärkung sowie der Abstützung des Gerüstbodens beim Ablegen auf einem Stützgrund und insbesondere der Lagezentrierung beim Stapeln, wie es Fig. 5 darstellt.The profile 100 has a lower wall 105, an upper wall 106, an inner wall 107 and an outer wall 108. In the lower outer corner 109, a known, essentially semi-cylindrical centering rib 110 is formed below the lower wall 105. It serves to reinforce and support the scaffold floor when it is placed on a support base and in particular to center the position when stacking, as shown in FIG. 5.

Ansonsten ist die Unterwand 105 an ihrer Außenfläche 111 glattflächig und horizontal geführt. Sie geht mit einer gerundeten oder abgeschrägten Ecke 112 in die glatte Außenfläche 113 der vertikalen Innenwand 107 über.Otherwise, the bottom wall 105 is guided on its outer surface 111 smoothly and horizontally. It merges with a rounded or beveled corner 112 into the smooth outer surface 113 of the vertical inner wall 107.

Oberhalb der Ecke 109 schließt sich an die Unterwand 105 die hier senkrechte Außenwand 108 an, die sich glattflächig bis nach oben zur oberen Eckrippe erstreckt. Diese steht um den Betrag 128 über die Außenwand 108 über und bildet hier eine besondere Verstärkung, die außerdem die Oberwand 131 als Auflage im Stapelzentrierungsfalz 130 bildet. Der Stapelzentrierungsfalz hat eine Breite 125, die geringfügig größer als die Breite 124 der Zentrier-Rippe 110 ist. Sie ist, wie Fig. 5 zeigt, räumlich so gelegt, daß beim Stapeln von zwei Böden übereinander, eine seitliche Verschiebung vermieden wird.Above the corner 109, the lower wall 105 is adjoined by the outer wall 108 which is vertical here and which extends smoothly up to the upper corner rib. This projects beyond the outer wall 108 by the amount 128 and here forms a special reinforcement which also forms the upper wall 131 as a support in the stacking centering fold 130. The stacking centering fold has a width 125 which is slightly larger than the width 124 of the centering rib 110. As shown in FIG. 5, it is spatially arranged in such a way that lateral displacement is avoided when two floors are stacked one on top of the other.

Die Verschiebebegrenzungs-Rippe 136 hat hier etwa die gleiche Breite wie der Stapelzentrierungsfalz 130 und bildet eine obere Trittfläche 87, die flache Rippen 52 und dazwischen Schmutz- und Wasserrinnen 51 aufweist.The displacement limiting rib 136 here has approximately the same width as the stack centering fold 130 and forms an upper tread surface 87 which has flat ribs 52 and dirt and water channels 51 therebetween.

Sie geht in eine Falzwand 42 über, die entweder etwa senkrecht angeordnet ist oder, wie bei diesem Ausführungsbeispiel, unten nach außen zur Verbreiterung der Nut verläuft. Sie reicht bis zum Nutgrund 70 der Entwässerungs- und Belüftungs-Nut 80, die zwischen der Vertikalfläche 81 am Rand 43 der Platte 45 und der Falzwand 42 gebildet ist und eine Mindestbreite 83 gegenüber der äußersten Auflagerippe 84 der Auflagefläche 41 aufweist. Diese ist so groß, daß bequem mit einer Kelle oder Spachtel in die Entwässerungs- und Belüftungs-Nut 80 zwecks Reinigung hineingefahren werden kann. Die Trittfläche 87 liegt neben der Entwässerungs- und Belüftungs-Nut 80 in beträchtlichem Abstand oberhalb der Auflagefläche 41. Der Abstand 85 oberhalb der Lauffläche 46 der Platte 45 ist so groß, daß der Plattenrand automatisch geschützt ist, andererseits jedoch keine so großen Hohlräume gebildet sind, daß man mit Schuh oder Absatz steckenbleiben könnte, vor allem aber ausreichend Raum ist, damit Flüssigkeit abfließen und die Stirnseiten der Platten 45 allseits belüftet werden können, so daß das vorhandene Holz auch bei sehr langjährigem Gebrauch nicht durch stehendes Wasser und fehlende Belüftung zur Verrottung neigt. So kann unter Umständen auf übermäßigen Gebrauch von Schimmelschutzmitteln und dgl. verzichtet werden.It merges into a rabbet wall 42, which is either arranged approximately vertically or, as in this exemplary embodiment, runs downwards to widen the groove. It extends to the groove bottom 70 of the drainage and ventilation groove 80, which is between the Vertical surface 81 is formed on the edge 43 of the plate 45 and the fold wall 42 and has a minimum width 83 with respect to the outermost support rib 84 of the support surface 41. This is so large that it can be conveniently moved into the drainage and ventilation groove 80 with a trowel or spatula for cleaning. The tread 87 lies next to the drainage and ventilation groove 80 at a considerable distance above the bearing surface 41. The distance 85 above the running surface 46 of the plate 45 is so great that the edge of the plate is automatically protected, but on the other hand no such large cavities are formed that you could get stuck with shoes or heels, but above all there is enough space so that liquid can drain off and the end faces of the plates 45 can be ventilated on all sides, so that the existing wood cannot rot, even after many years of use, from standing water and lack of ventilation tends. Under certain circumstances, excessive use of mold protection agents and the like can be dispensed with.

Nachfolgend wird ein wichtiger Teil der Beschreibung wiedergegeben:
Der Gerüstrahmenboden hat Längsholme (38.2) mit Kastenprofil. Diese haben an der unteren äußeren Ecke eine Zentrierrippe (110) und in der oberen äußeren Ecke einen Stapelzentrierungsfalz (130) neben einer Verschiebegrenzungs-Rippe (136). Diese liegt im Abstand vom Rand (43) der Platte (45) und bildet dadurch eine Entwässerungs- und Belüftungs-Nut (80).An important part of the description is given below:
The scaffold frame floor has longitudinal bars (38.2) with a box profile. These have a centering rib (110) on the lower outer corner and a stacking centering fold (130) in the upper outer corner next to a displacement limiting rib (136). This is at a distance from the edge (43) of the plate (45) and thereby forms a drainage and ventilation groove (80).
