Description

Die Erfindung betrifft einen Belag für Gerüste wie Fassadengerüste oder sonstige an Wänden oder Bauwerken zu errichtende Gerüste, wobei dieser Belag einen tafelförmigen Boden aufweist.The invention relates to a covering for scaffolding such as facade scaffolding or other scaffolding to be erected on walls or buildings, this covering having a tabular bottom.

Gerüst-Beläge sind horizontal anzuordnende Gerüstelemente, welche zwischen die senkrechten Träger eines Fassadengerüstes od. dgl. eingebaut werden und sowohl horizontale Tragelemente sind als auch zum Begehen bzw. als Unterlage zum Aufstellen von Bautmaterialien od. dgl. dienen.Scaffolding coverings are scaffolding elements to be arranged horizontally, which are installed between the vertical beams of a facade scaffolding or the like and which are both horizontal supporting elements and also for walking on or as a base for erecting building materials or the like.

Es ist bekannt, derartige Beläge sowohl in Holz als auch in Stahl und Aluminium auszuzuführen. Solche Beläge bezeichnet man auch, insbesondere wenn sie aus Holz bestehen, als Bohlen.It is known to carry out such coverings both in wood and in steel and aluminum. Such coverings are also called planks, especially if they are made of wood.

Der Werkstoff Holz verliert im Gerüstbau zunehmend an Bedeutung, wofür in erster Linie das Gewicht und die Brandgefahr verantwortlich sind, jedoch spielen auch sicherheitstechnische Überlegungen eine Rolle, denn Holz wird, wenn es naß ist, glitschig, so daß auf derartigen Belägen stehende oder gehende Personen leicht ausrutschen können.The material wood is becoming less and less important in scaffolding, which is primarily due to the weight and the risk of fire, but safety considerations also play a role, because wood becomes slippery when it is wet, so that people standing or walking on such coverings can slip easily.

Wegen des geringeren Gewichtes gewinnt der Werkstoff Aluminium im Gerüstbau immer mehr an Bedeutung. Ungünstig sind dabei aber die hohen Materialkosten von Aluminium. Hinzu kommt, daß in bestimmten Einsatzbereichen auch Brandgefahr besteht. So ist beispielsweise der Einsatz von Gerüstbauteilen aus Aluminium in vielen Kraftwerken nicht gestattet, da Aluminium bei hohen Temperaturen verbrennt.Because of its lower weight, aluminum is becoming increasingly important in scaffolding. However, the high material costs of aluminum are unfavorable. In addition, there is also a fire hazard in certain areas of application. For example, the use of aluminum scaffolding components is not permitted in many power plants because aluminum burns at high temperatures.

Aus diesen Gründen werden immer mehr Gerüstbeläge aus Stahl hergestellt. Aus schweißtechnischen Gründen und weil der Stahl zum Korrosionsschutz verzinkt wird, ist man an relativ großen Dicken der eingesetzten Stahlbleche gebunden, so daß sich relativ hohe Gewichte der einzelnen Beläge ergeben, was gerade im Gerüstbau nachteilig ist, da dort der manuelle Transport der Gerüstbauteile überwiegt.For these reasons, more and more scaffold coverings are made of steel. For welding reasons and because of the steel for corrosion protection is galvanized, one is bound to relatively large thicknesses of the steel sheets used, so that relatively high weights of the individual coverings result, which is disadvantageous especially in scaffolding, since manual transport of the scaffolding components predominates there.

Der Erfindung liegt die Aufgabe zugrunde, das Gewicht von aus Stahl hergestellten Gerüst-Belägen herabsetzen zu können.The invention has for its object to be able to reduce the weight of scaffold coverings made of steel.

Diese Aufgabe wird erfindungsgemäß mit einem Belag der eingangs genannten Gattung gelöst, welcher die Merkmale des kennzeichnenden Teiles des Patentanspruches 1 aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a covering of the type mentioned, which has the features of the characterizing part of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Der erfindungsgemäße Belag für Gerüste läßt sich aus verhältnismäßig dünnen verzinkten Stahlblechen und insbesondere sendzimirverzinkten Stahlblechen herstellen, da keine Schweißverbindungen notwendig sind. Ein Teil der Stahlbleche wird zu rechteckigen bis zu quadratischen Hohlprofilen gewalzt, welche in den Eckbereichen des reckteckigen bis quadratischen Querschnittes nach außen offene nutartige Vertiefungen aufweisen, die einen speziell geformten und vorzugsweise hinterschnittenen Querschnitt haben können. Jeweils zwei dieser im Querschnitt rechteckigen gewalzten Hohlprofile werden durch ebenfalls verzinkte und insbesondere sendzimirverzinkte dünnwandige Stahlbleche oder Zwischenbleche so miteinander verbunden, daß sie parallel zueinander gehalten sind. Die einzusetzenden Zwischenbleche weisen an ihren Längskanten rechtwinklig oder auch hakenförmig abgebogene Stege auf, die in einer Presse, d.h. also unter Druck, in die speziell geformten nutförmigen Vertiefungen der Profile gedrückt und dabei entsprechend verformt oder einfach in die hinterschnittenen Vertiefungen eingehängt werden.The covering for scaffolding according to the invention can be produced from relatively thin galvanized steel sheets and in particular Sendzimir galvanized steel sheets, since no welded connections are necessary. Some of the steel sheets are rolled into rectangular to square hollow profiles, which have groove-like recesses open to the outside in the corner regions of the rectangular to square cross section, which can have a specially shaped and preferably undercut cross section. In each case two of these hollow sections, which are rectangular in cross section, are connected to one another by thin-walled steel plates or intermediate plates, which are likewise galvanized and in particular Sendzimir galvanized, in such a way that they are held parallel to one another. The intermediate plates to be used have webs bent at right angles or hook-shaped on their longitudinal edges, which in a press, i.e. So under pressure, pressed into the specially shaped groove-shaped recesses of the profiles and thereby deformed accordingly or simply hooked into the undercut recesses.

Da die abgewinkelten Stege der als Zwischenelemente vorgesehenen Bleche im Vergleich zur Eckkonstruktion der gewalzten Hohlprofile wesentlich weicher sind, wird die Geometrie der Eckkonstruktion beim Eindrücken dieser Stege in die im Querschnitt nicht gradlinigen Nuten der Profile nicht verändert, während sich die Stege dabei verformen, so daß nach dem Einpreßvorgang die parallel zueinander verlaufenden rechteckigen Hohlprofile mit den dazwischen angeordneten Blechen sozusagen formschlüssig und damit dauerhaft und fest verbunden sind und ein ausgesteiftes rechteckiges Hohlprofil gebildet ist.Since the angled webs of the plates provided as intermediate elements are considerably softer than the corner construction of the rolled hollow profiles, the geometry of the corner construction becomes when the webs are pressed into the grooves of the profiles which are not straight in cross section does not change while the webs deform, so that after the pressing-in process, the parallel rectangular hollow profiles with the plates arranged between them are, so to speak, form-fitting and thus permanently and firmly connected, and a stiffened rectangular hollow profile is formed.

Wenn die beiden parallelen Hohlprofile einstückig mit einem sie verbindenden Zwischenblech geformt sind, braucht zum Fertigstellen des Belages bzw. der Bohle nur ein separat hergestelltes Zwischenblech eingebaut zu werden. In diesem Falle braucht das separate Zwischenblech in die Nuten der Hohlprofile nicht eingepreßt und dabei verformt zu werden, um eine formschlüssige Verbindung zu erzielen. Vielmehr kann man in diesem Falle das separate Zwischenblech mit hakenartigen Ansätzen versehen, welche in Nuten der Hohlprofile eingehängt werden können.If the two parallel hollow profiles are formed in one piece with an intermediate plate connecting them, only a separately produced intermediate plate needs to be installed to finish the covering or the screed. In this case, the separate intermediate plate does not need to be pressed into the grooves of the hollow profiles and deformed in the process in order to achieve a positive connection. Rather, in this case, the separate intermediate plate can be provided with hook-like projections, which can be hung in the grooves of the hollow profiles.

Durch die Erfindung ergibt sich der Vorteil, daß für die Ausgestaltung und den Zusammenbau der aus Stahlblech bestehenden Teile des Gerüst-Belages keine Schweißarbeiten oder auch keine aufwendigen Nietarbeiten notwendig sind. Daher kann man Stahlbleche mit wesentlich geringerer Dicke als bisher notwendig verarbeiten,so daß sich auch geringere Gesamtgewichte der erfindungsgemäß ausgebildeten Gerüstbeläge ergeben. Weiterhin ergibt sich der Vorteil, daß bei gleichbleibenden gewalzten Hohlprofilen durch Veränderungen der Breite der einfach ausgebildeten separaten Zwischenbleche oder Zwischenprofile eine Anpassung an individuelle Gerüstbreiten möglich ist. Auch können mehr als zwei rechteckige Profile durch Zwischenbleche in einer Einheit verbunden werden, so daß sowohl die Stabilität als auch die Breite erfindungsgemäßer Gerüst-Beläge variabel ist, ohne die Geometrie der eingesetzten gewalzten Rechteckprofile verändern zu müssen.The invention has the advantage that no welding or expensive riveting work is necessary for the design and assembly of the parts of the scaffolding covering made of sheet steel. Therefore, steel sheets can be processed with a much smaller thickness than previously necessary, so that there are also lower overall weights of the scaffold coverings designed according to the invention. Furthermore, there is the advantage that, with the rolled hollow profiles remaining the same, changes to the width of the simple intermediate plates or intermediate profiles can be adapted to individual frame widths. Also, more than two rectangular profiles can be connected in one unit by intermediate plates, so that both the stability and the width of scaffold coverings according to the invention can be varied without having to change the geometry of the rolled rectangular profiles used.

Ein für Gerüste wie Fassadengerüste bestimmter Belag besteht bei der Ausführungsform gemäß Fig. 1 in seiner Grundform aus zwei im Querschnitt rechteckigen Hohlprofilen 1 und 2 und aus zwei diese Hohlprofile untereinander verbindenden zunächst separat hergestellten Zwischenblechen 3 und 4. Sowohl die Hohlprofile 1 und 2 als auch die Zwischenbleche 3 und 4 sind aus dünnen Stahlblech gewalzt, wobei dieses Stahlblech verzinkt und insbesondere sendzimirverzinkt sein kann.A covering for scaffolding such as facade scaffolding consists in the embodiment according to FIG. 1 in its basic form of two hollow profiles 1 and 2 which are rectangular in cross section and of two intermediate plates 3 and 4 which initially connect these hollow profiles and are produced separately. Both the hollow profiles 1 and 2 as well the intermediate plates 3 and 4 are rolled from thin steel sheet, which steel sheet can be galvanized and in particular sendzimir galvanized.

Da die beiden Hohlprofile 1 und 2 ebenso wie die beiden Zwischenbleche 3 und 4 jeweils gleich ausgebildet sind, wird nachstehend nur das eine der beiden Hohlprofile und auch nur das eine der beiden Zwischenbleche im einzelnen beschrieben, um Wiederholungen zu vermeiden.Since the two hollow profiles 1 and 2, like the two intermediate plates 3 and 4, are each of the same design, only one of the two hollow profiles and only one of the two intermediate plates will be described in detail below, in order to avoid repetitions.

Jedes Hohlprofil 1 bzw. 2 ist aus einem dünnen und zuvor verzinkten Stahlblech 5 zu einem rechteckigen Querschnitt gewalzt, wobei in jeder Seite des rechteckigen Querschnittes sich ein aus dem Stahlblech gefalteter, nach innen weisender Steg 6 befindet, der durch eine Faltung des Stahlbleches 5 gebildet ist und zur Stabilisierung des Hohlprofiles dient. In der hier zeichnerisch kürzeren und nach außen weisenden Seitenwand 7 des Hohlprofils sind die Enden des das Hohlprofil 1 bzw. 2 bildenden Stahlbleches 5 formschlüssig miteinander verbunden, und zwar mittels eines nach innen weisenden abgekanteten Steges 8 und eines über diesen Steg 8 zurückgefalzten gegenüberliegenden weiteren Steges 9. Das Stahlblech 5 bildet somit ohne Schweißungen oder Nietverbindungen ein geschlossenes rechteckiges Hohlprofil 1 bzw. 2, das Teil des Gerüst-Belages ist. Die Verbindung der Kanten des Stahlbleches erfolgt mit Hilfe eines im Querschnitt U-förmiges Falzes, der in der Zeichnung erkennbar ist.Each hollow profile 1 or 2 is rolled from a thin and previously galvanized steel sheet 5 into a rectangular cross-section, with in each side of the rectangular cross-section there is a web 6 folded inward from the steel sheet and formed by folding the steel sheet 5 is and serves to stabilize the hollow profile. In the side wall 7 of the hollow profile, which is shorter in this drawing and points outwards, the ends of the steel sheet 5 forming the hollow profile 1 or 2 are positively connected to one another, namely by means of an inwardly pointing bent web 8 and an opposite further web folded back over this web 8 9. The steel sheet 5 thus forms a closed rectangular hollow profile 1 or 2 without welding or rivet connections, which is part of the scaffolding covering. The connection of the edges of the steel sheet takes place with the help of a U-shaped cross-section fold, which can be seen in the drawing.

Im Bereich der vier Ecken 11 des Hohlprofiles 1 bzw. 2 ist das Stahlblech 5 komplex derart verformt, daß ein nach außen offener, nach innen bogenförmig verlaufender Schlitz 12 gebildet ist, dessen Einlaufende 13 in derselben Ebene wie die entsprechende Seitenwand 14 des Hohlprofiles 1 bzw. 2 liegt oder mit dieser Seitenwand fluchtet. Ein nach außen vorstehender Ansatz 15 des profiliert gewalzten Stahlbleches 5 begrenzt den Schlitz 12 nach außen.In the area of the four corners 11 of the hollow profile 1 or 2, the steel sheet 5 is complex deformed such that an outwardly open, inwardly arcuate slot 12 is formed, the inlet end 13 in the same plane as the corresponding side wall 14 of the hollow profile 1 or 2 lies or is flush with this side wall. An outwardly projecting extension 15 of the profiled rolled steel sheet 5 delimits the slot 12 to the outside.

Die Zwischenbleche 3 und 4 sind zum Verbinden zweier benachbarter und sich parallel zueinander erstreckender Hohlprofile 1 und 2 vorgesehen. Jedes Zwischenblech ist ebenso wie jedes Hohlprofil aus dünnem und verzinktem Stahlblech 5 gewalzt und weist etwa in der Mitte einen doppelwandigen gefalteten Steg 6 auf, der, wie die Zeichnung zeigt, nach innen weist und wie die entsprechenden Stege der Hohlprofile 1 und 2 zur Stabilisierung bzw. Verstärkung des Zwischenbleches dient.The intermediate plates 3 and 4 are provided for connecting two adjacent and parallel hollow profiles 1 and 2. Each intermediate plate, like every hollow profile, is rolled from thin and galvanized sheet steel 5 and has a double-walled web 6 approximately in the middle, which, as the drawing shows, points inwards and how the corresponding webs of the hollow profiles 1 and 2 for stabilization or Reinforcement of the intermediate plate serves.

Jedes Zwischenblech 3 bzw. 4 weist an seinen beiden Längskanten einen zunächst rechtwinklig abgebogenen Rand 16 auf. Beim Zusammenfügen der Hohlprofile 1 und 2 mit den Zwischenblechen 3 und 4 werden die rechtwinklig abgebogenen Ränder 16 der Zwischenbleche 3 und 4 in das Einlaufende 13 der betreffenden Schlitze 12 der Hohlprofile 1 und 2 eingesteckt. Mittels einer hier nicht dargestellten Presse werden die Zwischenbleche 3 und 4 gegen die entsprechenden Hohlprofile 1 und 2 gedrückt, wobei die Ränder 16 der Zwischenbleche 3 und 4 der Krümmung der innerhalb der Hohlprofile 1 und 2 nach innen verlaufenden Schlitze 12 folgen und dabei dauerhaft verbogen werden, so daß schließlich eine formschlüssige Verbindung zwischen den Zwischenblechen 3 und 4 und den benachbarten Hohlprofilen 1 und 2 herbeigeführt ist und die Zwischenbleche mit der Oberseite bzw. der Unterseite der Hohlprofile 1 und 2 in einer Ebene liegen. Auch für diese Verbindung ist kein Schweißen oder Nieten erforderlich.Each intermediate plate 3 or 4 has an edge 16 which is initially bent at right angles on its two longitudinal edges. When joining the hollow profiles 1 and 2 with the intermediate plates 3 and 4, the right-angled edges 16 of the intermediate plates 3 and 4 are inserted into the inlet end 13 of the relevant slots 12 of the hollow profiles 1 and 2. The intermediate plates 3 and 4 are pressed against the corresponding hollow profiles 1 and 2 by means of a press (not shown here), the edges 16 of the intermediate plates 3 and 4 following the curvature of the slots 12 running inward within the hollow profiles 1 and 2 and thereby being permanently bent , so that finally a positive connection between the intermediate plates 3 and 4 and the adjacent hollow profiles 1 and 2 is brought about and the intermediate plates with the top and bottom of the hollow profiles 1 and 2 lie in one plane. No welding or riveting is required for this connection either.

Der so gebildete Belag hat insgesamt einen rechteckigen Qerschnitt, der aus zwei äußeren Hohlprofilen und dazwischen angeordneten Zwischenblechen besteht. Durch Anbauen weiterer Hohlprofile mit Hilfe von dazwischen angeordneten weiteren Zwischenblechen läßt sich der Belag in der Breite beliebig erweitern.The covering thus formed has an overall rectangular cross section, which consists of two outer hollow profiles and intermediate plates arranged between them. By adding further hollow profiles with the help of further intermediate plates arranged in between, the width of the covering can be expanded as desired.

Pfeile 17 deuten an, wie bzw. in welcher Richtung die Zwischenbleche 3 und 4 und deren Ränder 16 gegenüber den Hohlprofilen 1 und 2 bewegt werden, um die Zwischenbleche mit den Hohlprofilen dauerhaft zu verbinden.Arrows 17 indicate how or in which direction the intermediate plates 3 and 4 and their edges 16 are moved relative to the hollow profiles 1 and 2 in order to permanently connect the intermediate plates to the hollow profiles.

Der in Fig. 2 dargestellte Belag bildet ähnlich wie die Ausführungsform gemäß Fig. 1 in der Endausbaustufe eine im Querschnitt rechteckige Bohle, die als Gerüst-Belag geeignet ist. Gegenüber der Ausführungsform aus Fig. 1 ist jedoch die in Fig. 2 dargestellte Ausführungsform einfacher ausgebildet und daher preiswerter herzustellen.Similar to the embodiment according to FIG. 1, the covering shown in FIG. 2 in the final stage of construction forms a screed which is rectangular in cross section and is suitable as a scaffold covering. Compared to the embodiment from FIG. 1, however, the embodiment shown in FIG. 2 is simpler and therefore cheaper to manufacture.

Aus einem verhältnismäßig breiten verzinkten Stahlblech 18 sind zwei parallel zueinander verlaufende und im Querschnitt rechteckige Hohlprofile 19 und 20 geformt, die von einem aus dem Stahlblech 18 bestehenden Zwischenelement oder Zwischenblech 21 einstückig miteinander verbunden sind. Im jeweils oberen Abschnitt 22 bzw. 23 der beiden Hohlprofile 19 und 20 ist jeweils ein nach innen vorstehender Steg 24 vorgesehen, der als Verstärkung dient und aus dem Stahlblech 18 gefaltet ist.A relatively wide galvanized steel sheet 18 is formed into two hollow profiles 19 and 20 which run parallel to one another and are rectangular in cross section and which are integrally connected to one another by an intermediate element or intermediate sheet 21 consisting of the steel sheet 18. In each of the upper sections 22 and 23 of the two hollow profiles 19 and 20, an inwardly projecting web 24 is provided, which serves as a reinforcement and is folded out of the steel sheet 18.

Am - in Fig. 2 gesehen - unteren Ende der inneren Wand 25 jedes der Hohlprofile 19 und 20 ist jeweils ein nach außen vorstehender Flansch 26 abgewinkelt, der auf der Innenseite des Zwischenbleches 21 aufliegt und durch Druckfügen fest mit dem Zwischenblech 21 verbunden ist. Durch das Druckfügen ist wenigstens eine nach innen weisende Ausbeulung 27 entstanden.At the - seen in Fig. 2 - the lower end of the inner wall 25 of each of the hollow profiles 19 and 20, an outwardly projecting flange 26 is angled, which rests on the inside of the intermediate plate 21 and is firmly connected to the intermediate plate 21 by pressure joining. At least one bulge 27 pointing inwards has been created by the pressure joining.

Die beiden einstückig durch das Zwischenblech 21 miteinander verbundenen Hohlprofile 19 und 20 sind ein in sich bereits verhältnismäßig stabiles Gebilde, das seine endgültige Stabilität durch ein dem Zwischenblech 21 gegenüberliegend einzufügendes separates weiteres Zwischenblech 28 erhält.The two hollow profiles 19 and 20, which are integrally connected to one another by the intermediate plate 21, are an inherently relatively stable structure, which is given its final stability by an intermediate plate 21 receives another separate intermediate plate 28 to be inserted opposite.

Das zunächst separate Zwischenblech 28 besteht ebenfalls aus verzinktem Stahlblech und weist im mittleren Bereich einen als Verstärkung dienenden, nach innen weisenden Steg 29 auf, der durch eine Faltung des Stahlbleches entstanden ist. An den Längskanten des Zwischenbleches 28 befinden sich hakenartig ausgebildete, schräg nach einwärts weisende Ansätze 30, die mit einem nach auswärts weisenden abgewinkelten Flansch 31 enden.The intermediate plate 28, which is initially separate, likewise consists of galvanized steel plate and has in the central region a web 29 serving as reinforcement and pointing inwards, which is created by folding the steel plate. On the longitudinal edges of the intermediate plate 28 there are hook-like projections 30 which point obliquely inwards and which end with an angled flange 31 pointing outwards.

Die Ansätze 30 können, wenn das Zwischenblech 28 in Richtung von Pfeilen 32 gegen die Hohlprofile 19 und 20 bewegt wird, in an den inneren oberen Ecken der Hohlprofile befindliche hinterschnittene Nuten 33 eingehängt werden, wodurch der Gerüst-Belag gemäß Fig. 2 fertiggestellt wird.The lugs 30 can, when the intermediate plate 28 is moved in the direction of arrows 32 against the hollow profiles 19 and 20, be hooked into undercut grooves 33 located on the inner upper corners of the hollow profiles, as a result of which the scaffolding covering according to FIG. 2 is completed.

Obwohl es zweckmäßig ist, das Zwischenblech 28 in Richtung der Pfeile 32 auf die Hohlprofile aufzustecken und dabei sozusagen senkrecht zu der Oberfläche der Hohlprofile zu bewegen, kann man das Zwischenblech 28 auch von einer Stirnseite des Belages aufschieben.Although it is expedient to plug the intermediate plate 28 onto the hollow profiles in the direction of the arrows 32 and to move it so to speak perpendicularly to the surface of the hollow profiles, the intermediate plate 28 can also be pushed on from one end face of the covering.

In jedem Falle ist es zweckmäßig, beim Aufsetzen oder Aufschieben des Zwischenbleches 28 die Hohlprofile 19 und 20 etwas nach oben und damit gegeneinander zu drücken, damit sich die Nuten 33 in einem Ausmaß einander nähern, das ein leichtes Aufstecken oder Aufschieben des Zwischenbleches erlaubt. Befindet sich das Zwischenblech 28 in seiner gewünschten Endposition, können die Hohlprofile 19 und 20 losgelassen werden, so daß sie in ihrer Ausgangsposition zurückkehren und nunmehr eine feste, formschlüssige Verbindung zwischen dem Zwischenblech 28 und den Hohlprofilen 19 und 20 hergestellt ist.In any case, it is expedient to press the hollow profiles 19 and 20 somewhat upwards and thus against one another when the intermediate plate 28 is being put on or pushed on, so that the grooves 33 approach each other to an extent which allows the intermediate plate to be plugged on or pushed on easily. If the intermediate plate 28 is in its desired end position, the hollow profiles 19 and 20 can be released so that they return to their starting position and a firm, positive connection between the intermediate plate 28 and the hollow profiles 19 and 20 is now established.

Beim Bewegen der Hohlprofile 19 und 20 gegeneinander wird das diese verbindende Zwischenblech 21 gebogen. Da dieses Zwischenblech aus Stahlblech besteht, ist diese Biegung ohne dauerhafte Verformung möglich, so daß das Zwischenblech 21 die Hohlprofile 19 und 20 nach dem Aufsetzen des Zwischenbleches 28 in ihrer Ausgangslage zurückfedern läßt. Durch eine beim Verformen des Stahlbleches 18, das durch Walzen erfolgen kann, vorzusehende entgegengesetzte Wölbung des Zwischenbleches 21 kann dieser Rückfedereffekt noch verstärkt werden.When moving the hollow profiles 19 and 20 against each other, the intermediate plate 21 connecting them is bent. Since this intermediate plate is made of sheet steel, this bend is without permanent deformation possible so that the intermediate plate 21 allows the hollow profiles 19 and 20 to spring back in their initial position after the intermediate plate 28 has been put on. This resilience effect can be further intensified by an opposite curvature of the intermediate plate 21 that is to be provided when the steel plate 18 is deformed, which can be done by rolling.

Der in Fig. 3 und 4 dargestellte Belag ist in seiner Grundform ähnlich wie der Belag gemäß Fig. 2 ausgebildet, jedoch noch preiswerter herzustellen.The covering shown in FIGS. 3 and 4 is designed in its basic form similarly to the covering according to FIG. 2, but is even cheaper to produce.

Wiederum sind aus einem verhältnismäßig breiten verzinkten Stahlblech 18 zwei parallel zueinander verlaufende und im Querschnitt rechteckige Hohlprofile 34 und 35 geformt, die von einem aus dem Stahlblech 18 bestehenden Zwischenelement oder Zwischenblech 21 einstückig miteinander verbunden sind. Wie insbesondere Fig. 23 zeigt, sind die Hohlprofile 34 und 35 im Querschnitt als einfache Rechtecke geformt und somit noch einfacher ausgebildet als die Hohlprofile 19 und 20 der Ausführungsform gemäß Fig. 2. Auch bei der Ausführungsform gemäß Fig. 3 und 4 ist das untere Ende der inneren Wand 25 jedes der Hohlprofile 34 und 35 jeweils als nach außen vorstehender Flansch 26 abgewinkelt, der auf der Innenseite des Zwischenbleches 21 aufliegt und durch Druckfügen fest mit dem Zwischenblech verbunden ist. Die durch das Druckfügen entstandenen, nach innen weisende Ausbeulungen 27 sind insbesondere in Fig. 4 zu erkennen.Again, from a relatively wide galvanized steel sheet 18 two parallel and rectangular in cross-section hollow sections 34 and 35 are formed, which are integrally connected to each other by an intermediate element or intermediate sheet 21 made of steel sheet 18. As shown in FIG. 23 in particular, the hollow profiles 34 and 35 are shaped as simple rectangles in cross-section and are thus even simpler than the hollow profiles 19 and 20 of the embodiment according to FIG. 2. Also in the embodiment according to FIGS. 3 and 4 the lower one End of the inner wall 25 of each of the hollow profiles 34 and 35 each angled as an outwardly projecting flange 26 which rests on the inside of the intermediate plate 21 and is firmly connected to the intermediate plate by pressure joining. The inward bulges 27 resulting from the pressure joining can be seen in particular in FIG. 4.

Bei der Ausführungsform gemäß Fig. 3 und 4 sind die Hohlprofile 34 und 35 außerdem mittels bandförmigen Laschen 36, die dem Zwischenblech 21 gegenüberliegend angeordnet sind, untereinander verbunden. Die laschen 36 sind schmale Blechstreifen, die in einem gegeneitigen Abstand von beispielsweise etwa einem Meter vorgesehen sind. Bei der Ausführungsform gemäß Fig. 3 und 4 liegen diese Laschen 36 mit ihren beiden Enden 37 und 38 auf der Außenseite 40 bzw. der Hohlprofile 34 und 35 auf und sind mittels Nieten 41 an diesen Hohlprofilen befestigt.In the embodiment according to FIGS. 3 and 4, the hollow profiles 34 and 35 are also connected to one another by means of band-shaped tabs 36 which are arranged opposite the intermediate plate 21. The tabs 36 are narrow metal strips that are provided at a mutual distance of, for example, about one meter. 3 and 4, these tabs 36 lie with their two ends 37 and 38 on the outside 40 or the hollow profiles 34 and 35 and are fastened to these hollow profiles by means of rivets 41.

Das Annieten der Laschen 36 ist eine besonders vorteilhafte Verbindungsart. Da zum Verbinden der dem Zwischenblech 21 gegenüberliegenden Seiten der Hohlprofile 34 und 35 kein durchgehendes Blech benötigt wird, sondern in größerem Abstand voneinander, beispielsweise im Abstand von etwa einem Meter, angeordnete schmale streifenförmige Laschen 36, kann das Gesamtgewicht des Belages weiter verringert werden.The riveting of the tabs 36 is a particularly advantageous type of connection. Since no continuous sheet is required to connect the sides of the hollow profiles 34 and 35 opposite the intermediate sheet 21, but rather narrow strip-shaped tabs 36 arranged at a greater distance from one another, for example at a distance of about one meter, the total weight of the covering can be reduced further.

Bei der Ausführungsform gemäß Fig. 3 und 4 wird der Belag zweckmäßig so im Gerüst angeordnet, daß die Laschen 36 nach unten weisen.In the embodiment according to FIGS. 3 and 4, the covering is expediently arranged in the frame so that the tabs 36 point downward.

In Fig. 4 ist durch strichpunktierte Linien 42 angedeutet, daß die in dieser Zeichnungsfigur gezeigte Draufsicht nur einen Teilausschnitt eines Gerüst-Belages im Bereich einer als Verbindungselement verwendeten Lasche 36 zeigt. Der Belag ist tatsächlich wesentlich länger und kann den Abstand zwischen zwei benachbarten senkrechten Säulen eines Traggerüstes überbrücken.4, dash-dotted lines 42 indicate that the plan view shown in this drawing figure shows only a partial section of a scaffold covering in the area of a tab 36 used as a connecting element. The covering is actually much longer and can bridge the distance between two adjacent vertical columns of a supporting structure.
