Abstract

The platform for scaffolds, in particular for tubular steel scaffolds, consists of shear-resistant boards which possess, at the end faces, hook-shaped holding fixtures for positive fastening to the crossmembers of the scaffold so as to bear on said members, and are secured against arbitrary lifting off. Additional fastening elements (12, 18), which interconnect in a dimensionally stable and rigid manner two boards (10) laid one behind the other, are provided at the end faces of the boards (10). The platforms according to the invention are suitable for various types of scaffolds, e.g. for frame scaffolds and also modular scaffolds, and act as bracing means for the entire scaffold structure, rendering superfluous in certain cases the use of longitudinal and/or diagonal members. <IMAGE>

Description

Die Erfindung betrifft einen Gerüstbelag für Baugerüste, insbesondere für Stahlrohrgerüste, bestehend aus schub­steifen Dielen, die an den Stirnseiten hakenförmige Halterungen zur formschlüssigen Auflage-Befestigung an den Querriegeln des Baugerüsts aufweisen und gegen willkürliches Abheben von den Querriegeln gesichert sind.The invention relates to a scaffolding covering for scaffolding, in particular for tubular steel scaffolding, consisting of shear-resistant planks, which have hook-shaped brackets on the end faces for form-fitting support attachment to the crossbars of the scaffolding and are secured against arbitrary lifting off the crossbars.

Gerüstbeläge bilden die Laufstege und Arbeits-Stand­flächen für die auf dem Gerüst beschäftigten Personen und gehören aus diesem Grunde zu den wichtigsten Elemen­ten eines Baugerüstes. Daneben haben sie jedoch noch die weitere wichtige Funktion einer Längs- und Querverstei­fung der gesamten Gerüstkonstruktion. Aufgrund dieser besonderen Bedeutung für die Standfestigkeit des Bau­gerüstes und für die Sicherheit der auf dem Gerüst be­schäftigten Personen bestehen in verschiedenen Ländern strenge Bestimmungen für die Eigenschaften der einzelnen Dielen sowie für ihre Verlegung und sichere Befestigung.Scaffolding coverings form the catwalks and work stands for the people working on the scaffolding and are therefore one of the most important elements of scaffolding. In addition, however, they also have the other important function of longitudinal and transverse stiffening of the entire scaffolding structure. Due to this special importance for the stability of the scaffolding and for the safety of the people working on the scaffolding, there are strict regulations in various countries for the properties of the individual planks as well as for their laying and secure fastening.

Bei den sog. Rahmengerüsten, deren Rahmen aus zwei seit­lichen Stahlrohrständern und zwei mit diesen verschweißten Querriegeln bestehen, sind Beläge bekannt, deren Dielen an den Stirnseiten formsteife Haken tragen. Die oberen Querriegel jedes Rahmens sind in Form eines nach oben offenen U-Profils ausgebildet, in dessen vertikale Seitenschenkel die Dielen mit den stirnseitigen Haken eingehängt werden. Um ein unbeabsichtigtes oder will­kürliches Herausheben der Dielen bzw. ihrer Haken aus den U-Profilen der Querriegel zu vermeiden, sind die unteren Querriegel das nächstoberen Gerüstes als Rohre ausgebildet und in einem solchen Abstand angeordnet, daß sie von oben gegen die Haken drücken und/oder eine Aushebebewegung der Haken nach oben verhindern. Diese Gerüstbeläge sind für sog. Modul-Gerüste, die aus einzelnen Rohrständern und an deren Tragkonsolen mon­tierten rohrförmigen Querriegeln vor Ort zusammengebaut werden, nicht einsetzbar. Darüber hinaus verleihen diese bekannten Gerüstbeläge den Baugerüsten eine häufig unzureichende Steifigkeit in Richtung der Querriegel, d.h. senkrecht zu den Fassadenwänden.In the so-called frame frameworks, the frames of which consist of two lateral tubular steel stands and two crossbars welded to them, coverings are known whose planks carry dimensionally stable hooks on the end faces. The top Crossbars of each frame are designed in the form of an upwardly open U-profile, in the vertical side legs of which the planks are hung with the hooks on the front. In order to avoid unintentional or arbitrary lifting of the planks or their hooks from the U-profiles of the crossbars, the lower crossbars of the next upper scaffold are designed as tubes and are arranged at such a distance that they press against the hooks from above and / or prevent lifting of the hooks upwards. These scaffolding coverings cannot be used for so-called modular scaffolds that are assembled on site from individual tube stands and tubular crossbars mounted on their support brackets. In addition, these known scaffolding coverings often give the scaffolding insufficient rigidity in the direction of the crossbars, ie perpendicular to the facade walls.

Bei einer anderen Ausführung der Gerüstbeläge für Rahmengerüste weisen die Dielen an ihren stirnseitigen Enden mehrere Querbohrungen auf. Die zur Abstützung dieser Dielen vorgesehenen Querriegel der einzelnen Rahmen sind als z.B. Vierkantprofil ausgeführt und tragen an ihren beiden Seiten nach oben vorstehende Zapfen, welche so angeordnet und an den Querriegeln fest ange­schweißt sind, daß sie beim Verlegen der Dielen in deren stirnseitige Löcher eingreifen, Dabei ergibt sich zwar ein sicherer Formschluß zwischen den an den Quer­riegeln sitzenden Stiften und den Bohlen, Voraussetzung ist jedoch die Verwendung von Querriegeln mit seitlich überstehenden Zapfen oder Vierkant-Querschnitt, um eine ausreichende Auflagefläche für die Dielen zu gewähr­leisten. Der Nachteil dieser Riegelausführung besteht darin, daß auf diese Riegel wegen der überstehenden Zapfen, insbesondere in den Modul-Gerüsten, keine handelsüblichen Dielen verlegt werden können. Auch die für Rahmenmgerüste geeigneten Dielen können nicht auf die üblichen rohrförmigen Riegel bei Modul- und sonstigen Rohrgerüsten mit gleichen Achsabständen verlegt werden, da sie zu kurz sind und damit auf diesen Riegeln nicht aufgelegt werden können. Aus diesem Grunde ist eine Anwendung dieser Gerüstbeläge bei modernen Modul-Gerüsten nicht möglich.In another version of the scaffolding coverings for frame scaffolds, the planks have a plurality of cross holes at their front ends. The crossbars provided for supporting these planks of the individual frames are designed, for example, as a square profile and have upwardly projecting pegs on both sides, which are arranged and welded to the crossbars so that they engage in the end holes of the planks when laying the planks Although there is a secure positive fit between the pins on the crossbars and the planks, the prerequisite is the use of crossbars with laterally protruding pegs or a square cross-section to ensure a sufficient contact surface for the planks. The disadvantage of this bolt design is that there are none on these bolts because of the protruding pins, particularly in the module frames commercially available planks can be installed. Even the planks suitable for frame scaffolding cannot be installed on the usual tubular transoms with modular and other tubular scaffolding with the same center distances, since they are too short and therefore cannot be placed on these transoms. For this reason, it is not possible to use these scaffolding coverings with modern modular scaffolding.

Modul-Gerüste zeichnen sich bekanntlich dadurch aus, daß sie nicht aus einzelnen in sich formsteifen Rahmen sondern aus einer Vielzahl von Einzelteilen bestehen, die vor Ort dann in individueller und vielgestaltiger Weise zusammengebaut werden können. Die verwendeten Rohrständer besitzen in vorgegebenen vertikalen Ab­ständen formsteife ringförmige Tragkonsolen, an denen die Längsstreben und auch die Querriegel mit Hilfe be­sonderer Befestigungselemente angeschlossen werden. Der Vorteil derartiger Modul-Gerüste ist ihre univer­selle Anwendbarkeit und die Vielgestaltigkeit ihrer Anpassung an unterschiedliche Bauwerke. Problematisch kann jedoch unter Umständen die Erzielung der geforder­ten Steifigkeit der Gerüstkonstruktion sein. Zur hori­zontalen Aussteifung sind bei diesem Gerüsttyp rohr­förmige Längs- und Querriegel erforderlich, deren Enden über geeignete Keilverbindungen od. dgl. an den ring­förmigen Tragkonsolen der Stahlrohrständer befestigt werden. Die Rohrprofile der Längs- und Querriegel sind notwendig, um die hohen wirksamen Kräfte ohne Deforma­tionen aufnehmen und übertragen zu können. Zur Befesti­gung des Gleitbelages auf den Querriegeln sind haken­förmige Klauen an den beiden Stirnseiten der Dielen mit gegenseitiger Versetzung angeschweißt, deren innere Auflagefläche entsprechend den Riegeldurchmessern ge­rundet ist und die die Querriegel übergreifen. Eine wirksame Gerüstversteifung, insbesondere gegenüber den quer zur vertikalen Außenfläche des Bauwerks wirkenden Kräften, läßt sich nicht erreichen.As is well known, modular scaffolds are characterized by the fact that they do not consist of individual, inherently rigid frames but of a large number of individual parts which can then be assembled on site in an individual and varied manner. The pipe stands used have dimensionally stable, ring-shaped support brackets at predetermined vertical intervals, to which the longitudinal struts and also the crossbars are connected using special fastening elements. The advantage of such modular scaffolding is its universal applicability and the diversity of its adaptation to different structures. Under certain circumstances, however, achieving the required rigidity of the scaffold structure can be problematic. For horizontal bracing, tubular longitudinal and transverse bars are required for this type of scaffold, the ends of which are fastened to the ring-shaped support brackets of the tubular steel stands by means of suitable wedge connections or the like. The tubular profiles of the longitudinal and crossbeams are necessary to absorb and transmit the high effective forces without deformation. To fix the sliding surface on the crossbars, hook-shaped claws are welded to the two end faces of the planks with mutual displacement, the inner contact surface of which is rounded in accordance with the crossbar diameters and which overlap the crossbars. An effective scaffold stiffening, especially against the Forces acting transversely to the vertical outer surface of the building cannot be achieved.

Aufgabe der Erfindung ist es, einen Gerüstbelag zu schaffen, der für Rahmengerüste ebenso wie für Modul-­Gerüste ohne Umrüstung geeignet ist und der eine wirk­same horizontale Aussteifung der Gerüstkonstruktion be­wirkt.The object of the invention is to provide a scaffolding covering which is suitable for frame scaffolding as well as for modular scaffolding without retrofitting and which brings about an effective horizontal stiffening of the scaffolding construction.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the features of claim 1.

Durch die erfindungsgemäße zusätzliche starre und form­schlüssige gegenseitige Verbindung der Stirnseiten der hintereinander verlegten Dielen durch besondere Verbin­dungsmittel werden die auf bestimmte Dielen bzw. auf entsprechende Gerüstabschnitte einwirkenden horizontalen Schub- und Zugkräfte nicht - wie bisher - nur auf den die jeweiligen Dielen tragenden Querriegel, sondern auch von einer Diele auf die nächstfolgende übertragen. Der allseitig wirkende Formschluß dieser erfindungsge­mäßen Dielenverbindung bewirkt somit eine wesentliche Versteifung der Gerüstkonstruktion, und zwar insbeson­dere gegenüber den in Richtung der Längsachse der Quer­riegel wirkenden Kräften quer zur Außenwand des Bauwerks. Versuche haben ergeben, daß durch die zusätzliche Ver­bindung der Dielen-Stirnseiten untereinander diese Quer­steifigkeit eines Modul-Gerüstes gegenüber herkömmlichen Gerüsten um ein Vielfaches gesteigert wird.Due to the additional rigid and positive mutual connection of the end faces of the boards laid one behind the other by means of special connecting means, the horizontal thrust and tensile forces acting on certain boards or on corresponding scaffold sections are not - as was previously the case - only on the crossbars carrying the respective boards, but also transferred from one hall to the next. The all-round positive locking of this board connection according to the invention thus brings about a substantial stiffening of the scaffold structure, in particular with respect to the forces acting in the direction of the longitudinal axis of the crossbars transversely to the outer wall of the structure. Tests have shown that the transverse stiffness of a modular scaffold is increased by a multiple compared to conventional scaffolds by the additional connection of the end faces of the planks.

Bei einer besonders zweckmäßigen Ausgestaltung der Er­findung bestehen die zusätzlichen Befestigungselemente aus U-förmigen Krampen, die von oben in entsprechend positionierte Löcher an den Stirnenden zweier benach­barter Dielen eingreifen. Diese U-förmigen Krampen über­ tragen nicht nur die in Längsrichtung der Dielen wirk­samen Schub- und Zugkräfte von einer Diele zur anderen, sondern können auch die quer zur Wand des Bauwerks nach außen wirkenden "Abzugskräfte" aufnehmen und damit die gesamte Gerüstkonstruktion wirksam aussteifen.In a particularly expedient embodiment of the invention, the additional fastening elements consist of U-shaped staples which engage from above in correspondingly positioned holes at the ends of two adjacent planks. These U-shaped cramps over not only bear the shear and tensile forces effective in the longitudinal direction of the planks from one plank to the other, but can also absorb the "pulling forces" acting outwards transversely to the wall of the building and thus effectively stiffen the entire scaffolding structure.

Zweckmäßig sind mehrere dieser Krampen an der Unter­seite von Querstreben angeschweißt. Diese Ausführung hat die besonderen Vorteile, daß sich nicht nur der Versteifungseffekt vergrößert, sondern gleichzeitig auch die Montage and Verlegung der Gerüstbeläge ver­einfacht. Ferner können die so ausgebildeten Dielen als Gerüstbeläge für Rahmengerüste ebenso wie für Modul-Gerüste verwendet werden, was sich bezüglich der Lagerhaltung und auch der Montage vorteilhaft aus­wirkt. Die hohe Versteifungswirkung dieser Gerüstbeläge hat den weiteren praktischen Vorteil, daß die bisher zur Erzielung der erforderlichen Steifigkeit notwendi­gen Längsriegel häufig entfallen können, was die Kosten des gesamten Gerüstes und dessen Auf- und Abbau erheb­lich vermindert. Für besonders hoch belastete Modul-­Gerüste können natürlich von Fall zu Fall in herkömm­licher Weise zusätzliche Versteifungswirkungen durch Verwendung von Längs- und/oder Diagonalriegeln erzielt werden.Appropriately, several of these staples are welded to the underside of cross struts. This version has the particular advantages that not only the stiffening effect increases, but also the assembly and laying of the scaffolding decking is simplified. Furthermore, the planks designed in this way can be used as scaffolding coverings for frame scaffolding as well as for modular scaffolding, which has an advantageous effect with regard to storage and also assembly. The high stiffening effect of these scaffolding coverings has the further practical advantage that the longitudinal bars previously required to achieve the required rigidity can often be dispensed with, which considerably reduces the costs of the entire scaffolding and its assembly and disassembly. For particularly highly loaded module scaffolds, additional stiffening effects can of course be achieved in the conventional manner by using longitudinal and / or diagonal bars.

Die die nach unten weisenden Krampen tragenden Quer­streben sind zweckmäßig als Flacheisen ausgebildet und greifen in entsprechende Einsenkungen an den Stirn­rändern der beiden hintereinander verlegten Dielen ein, so daß ihre Oberfläche in etwa mit der Oberfläche der Dielen übereinstimmt.The cross struts bearing the downward-facing cramps are expediently designed as flat irons and engage in corresponding depressions on the end edges of the two planks laid one behind the other, so that their surface corresponds approximately to the surface of the planks.

Gemäß einer anderen zweckmäßigen Ausgestaltung der Er­findung kann jede Diele an ihrer einen Stirnseite min­destens zwei Löcher und an der anderen Stirnseite zwei Zapfen für den Eingriff in die Löcher der nächstfolgen­den Diele aufweisen. Zweckmäßig sind die Zapfen an der Unterseite von Laschen befestigt, welche die angrenzen­den Randstreifen der benachbarten Diele übergreifen.According to another expedient embodiment of the invention, each plank can have at least one two holes on one end face and two pins on the other end face for engaging in the holes of the next plank. The pins are expediently fastened to the underside of tabs which overlap the adjacent edge strips of the adjacent plank.

Die bisher übliche untere Querverbindung der Rahmen, die vorwiegend aus Rund-, Quadrat- und Recheckrohren besteht und damit eine Stolpergefahr vorgibt, wird durch die Flacheisen oder z.B. Halbrundprofile ersetzt, an deren Unterseite die Verbindungszapfen befestigt sind. Die Stolpergefahr ist durch die damit geänderte untere Querverbindung behoben.The previously common lower cross connection of the frames, which mainly consists of round, square and rectangular tubes and thus pretends to trip, is replaced by the flat bars or e.g. Half-round profiles replaced, on the underside of which the connecting pins are attached. The risk of tripping is eliminated by the modified lower cross connection.

Die einzelnen Dielen des erfindungsgemäßen Gerüstbelages bestehen vorteilhaft aus einem gelochten Stahlblech und haben im Querschnitt die Form eines Kastenprofils mit nach innen eingebogenen unteren Randkanten. Die Löcher für den Eingriff der Krampen bzw. der Stifte sind vor­zugsweise in horizontalen Laschen von vehrfach abge­winkelten Profilteilen mit seitlichen Zungen ausgeführt. Diese Profilteile werden von der Stirnseiten her in das Kastenprofil der Dielen auf Maß eingeschoben und fest verschweißt.The individual planks of the scaffolding covering according to the invention advantageously consist of a perforated steel sheet and have the shape of a box profile in cross-section with inwardly bent lower edge edges. The holes for the engagement of the staples or the pins are preferably carried out in horizontal tabs of multi-angled profile parts with lateral tongues. These profile parts are pushed into the box profile of the planks from the front and welded to size.

The tubular steel stands 3, 4 of the upper frame 2 are attached with their downwardly open ends to vertical longitudinal pins 7, 8, which are attached to the upper end of the two tubular steel stands 3ʹ, 4ʹ of the lower frame above. The upper crossbars 6 of each frame serve as supporting elements for floorboards 10, which in the exemplary embodiment according to FIG. 1 are each laid twice next to one another and form the scaffolding covering. A profile element made of, for example, bent steel sheet is welded to the two end faces of each plank 10 and has a tab 11 projecting in the longitudinal direction over the end edge of the actual plank, in which two through transverse holes 12 are formed. The positioning is carried out so that the holes of two planks laid one behind the other are exactly opposite. Hook-shaped claws 14 are also welded to the underside of the tabs 11, as are shown, for example, in FIG. 4 and are also used in conventional modular scaffolding. These claws overlap in the Darge in Fig. 4 set the respective cross bar, the claws 14 on one end of the plank 10 with respect to the claws 14 on the other end side are laterally offset from each other by predetermined amounts in order to enable a common overlap of the tubular cross bar 6.

Bei der dargestellten Ausführung bestehen die einzelnen Dielen aus Stahlblech, das zu einem Kastenprofil mit einer ggf. aufgerauhten Tragfläche und nach unten ab­gebogenen Seitenwänden 15 sowie nach innen eingebogenen Randkanten 16 besteht. Die aus mehrfach abgewinkelten Stahlblechzuschnitten gebildeten Profilteile 13, die an ihrer Stirnseite die Laschen 12 tragen, sind in die offenen Stirnenden der Kastenprofile eingeschoben und verschweißt. Zur Tragfläche der kastenförmigen Stahlblech-Dielen 10 bilden die vorstehenden Laschen 11 einen Absatz, dessen Höhe in etwa der Wandstärke des Dielen-Stahlblechs entspricht. Bei Verwendung von anders geformten Dielen aus Stahlblech oder anderen geeigneten Materialien kann die durch die Laschen gegen­über der Tragfläche der Diele gebildete Einsenkung auch auf andere Weise hergestellt werden.In the embodiment shown, the individual planks are made of sheet steel, which consists of a box profile with a possibly roughened wing and side walls 15 bent downwards and edge edges 16 bent inwards. The formed from multi-angled sheet steel sections 13, which carry the tabs 12 on their end face, are inserted and welded into the open ends of the box sections. The protruding tabs 11 form a shoulder to the wing of the box-shaped steel sheet floorboards 10, the height of which corresponds approximately to the wall thickness of the floorboard steel sheet. When using differently shaped planks made of sheet steel or other suitable materials, the depression formed by the tabs in relation to the supporting surface of the plank can also be produced in another way.

Wie in Fig. 1 dargestellt, ist die untere Querstrebe 5 des oberen Rahmens 2 aus einem Flacheisen ausgeführt und trägt an ihrer Unterseite insgesamt vier U-förmige Krampen 18, die in Längsrichtung des Gerüstbelages aus­gerichtet und an der Querstrebe 5 in vorbestimmten Ab­ständen angeschweißt sind. Die Position und die Größe dieser U-Krampen 18 ist so gewählt, daß sie bei einer Absenkbewegung des oberen Rahmens in die Lochpaare 12 jeweils zweier benachbarter Laschen 11 an den beiden zueinander weisenden Stirnseiten von im Abstand zu­einander verlegten Dielen 10 eingreifen und auf diese Weise die Dielen zusätzlich zu ihrer Halterung auf den Querstreben 6 mittels der hakenförmigen Klauen 14 formsteif miteinander verbinden.As shown in Fig. 1, the lower cross strut 5 of the upper frame 2 is made of a flat iron and carries on its underside a total of four U-shaped cramps 18, which are aligned in the longitudinal direction of the scaffold covering and are welded to the cross strut 5 at predetermined intervals. The position and size of these U-clamps 18 is selected so that they engage in a lowering movement of the upper frame in the pairs of holes 12 of two adjacent tabs 11 on the two mutually facing end faces of boards 10 laid at a distance from one another and in this way the In addition to holding them on the cross struts 6, connect the floorboards to one another in a dimensionally stable manner by means of the hook-shaped claws 14.

Die in Fig. 2 dargestellte Ausführung entspricht in ihrem wesentlichen Aufbau der Ausführung nach Fig. 2, wobei gleiche Bezugszeichen für gleiche Bauteile ver­wendet sind. Statt einer Doppellage wie bei der Aus­führung nach Fig. 1 besteht der Gerüstbelag aus jeweils drei nebeneinander verlegten Dielen 10, welche mit den Dielen 10 der Ausführung nach Fig. 1 identisch sind. Diese Dielen 10 werden als Gerüstbelag bei einem sog. Modul-Gerüst verwendet, an dessen vertikalen Stahlrohr­ständern 23, 24 in vorgegebenen Abständen ringförmige Tragkonsolen 25 angeschweißt sind. Diese Tragkonsolen dienen in üblicher Weise zum festen Anschluß von Quer- und/oder Längsriegeln mit Hilfe von besonderen Befesti­gungselementen, welche die Kragen der Ringkonsolen um­greifen und ggf. durch Keile oder Schwenkhebel gesichert werden. Die verwendeten Querriegel 26 haben Rohrprofil und dienen als Auflageelemente für die Dielen 10, welche in der in Fig. 4 unten dargestellten Weise von den an den stirnseitigen Laschen 11 der Dielen angeschweißten hakenförmigen Klauen übergriffen werden. Als weiterer Unterschied gegenüber der Ausführung nach Fig. 1 sind die Krampen 18 an der Unterseite einer Querstrebe 27 angeschweißt, die als gesamtes Bauteil in Flachprofil, z.B. als Flacheisen, ausgebildet ist. Nachdem die ver­schiedenen Dielen 10 in der in Fig. 2 dargestellten Weise auf der Querstrebe positioniert worden sind, wird das Flacheisen 27 so über die Dielenlaschen 11 gelegt, daß die Zapfen der Krampen 18 in die jeweiligen Lochpaare 12 eingreifen. Aufgrund der Einsenkung schließt die Oberfläche der flachen Profilstrebe 17 mit den Oberflächen der Dielen zumindest in etwa ab, so daß der gesamte Gleitbelag eine weitgehend ebene Gehfläche erhält und Stolpergefahren vermieden werden.The embodiment shown in FIG. 2 corresponds in its essential structure to the embodiment according to FIG. 2, the same reference numerals being used for the same components. Instead of a double layer as in the embodiment according to FIG. 1, the scaffolding covering consists of three planks 10 laid next to one another, which are identical to the planks 10 of the embodiment according to FIG. 1. These planks 10 are used as scaffolding covering in a so-called modular scaffolding, on the vertical tubular steel stands 23, 24 of which annular support brackets 25 are welded at predetermined intervals. These support brackets are used in the usual way for the fixed connection of cross and / or longitudinal bolts with the help of special fastening elements which encompass the collar of the ring brackets and, if necessary, are secured by wedges or pivot levers. The crossbars 26 used have a tubular profile and serve as support elements for the floorboards 10, which in the manner shown in FIG. 4 below are overlapped by the hook-shaped claws welded to the end plates 11 of the floorboards. As a further difference compared to the embodiment according to FIG. 1, the staples 18 are welded to the underside of a cross strut 27, which is designed as an entire component in a flat profile, for example as a flat iron. After the various planks 10 have been positioned on the cross strut in the manner shown in FIG. 2, the flat iron 27 is placed over the plank flaps 11 in such a way that the pins of the staples 18 engage in the respective pairs of holes 12. Due to the depression, the surface of the flat profile strut 17 at least approximately closes with the surfaces of the planks, so that the entire sliding surface is given a largely flat walking surface and tripping hazards are avoided.

Die in den Fig. 3 und 4 dargestellte Ausführung des erfindungsgemäßen Gerüstbelages besteht ebenfalls aus mehreren hintereinander und ggf. auch nebeneinander verlegten Dielen 30, die aus geformtem Stahlblech, aus Holzbohlen und/oder auch aus anderen geeigneten Materialien bestehen können. Die Dielen 30 weisen an ihren beiden Stirnflächen vorstehende flache Laschen 31, 32 auf, an deren Unterseite die hakenförmigen Klauen 14, 15 angeschweißt sind. Wie aus Fig. 3 er­sichtlich, befinden sich an den seitlichen Verlänge­rungen 33 der Laschen 31 Bolzen 34, 35, die neben den hakenförmigen Klauen 14, 15 an der Unterseite ange­schweißt sind. Beim Zusammenbau zweier Dielen 30 greift jeweils einer dieser beiden Bolzen 34, 35 in die Quer­bohrung 36, 37 ein, die in der Lasche 32 ausgebildet ist, wodurch eine direkte Verbindung der Stirnseiten der beiden Dielen 30 zusätzlich zu ihrer Halterung durch die hakenförmigen Klauen 14, 15 auf dem Quer­riegel zustandekommt.The embodiment of the scaffolding covering according to the invention shown in FIGS. 3 and 4 likewise consists of a plurality of planks 30 laid one behind the other and possibly also next to one another, which can consist of shaped steel sheet, wooden planks and / or also of other suitable materials. The planks 30 have flat tabs 31, 32 protruding on their two end faces, on the underside of which the hook-shaped claws 14, 15 are welded. As can be seen from FIG. 3, there are bolts 34, 35 on the side extensions 33 of the tabs 31, which are welded on the underside in addition to the hook-shaped claws 14, 15. When assembling two planks 30, one of these two bolts 34, 35 engages in the transverse bore 36, 37, which is formed in the tab 32, whereby a direct connection of the end faces of the two planks 30 in addition to their mounting by the hook-shaped claws 14, 15 comes about on the crossbar.

Die Erfindung ist nicht auf die dargestellten Ausfüh­rungsbeispiele beschränkt. So können insbesondere auch andere Mittel zur direkten beidendigen Verbindung zweier auf einem Gerüst verlegter Dielen Verwendung finden, die einen Formschluß in Dielenlängsrichtung ebenso wie in Dielenquerrichtung gewährleisten. Ob­gleich die Verwendung von Kastenprofilen aus geformtem Stahlblech zur Herstellung der Dielen besonders zweck­mäßig ist, können auch andere Dielen, z.B. aus Holz­brettern zusammengebaute Dielen, Roste od. dgl. Ver­wendung finden.The invention is not restricted to the exemplary embodiments shown. In particular, other means for the direct connection at both ends of two planks laid on a scaffold can also be used, which ensure a positive connection in the longitudinal direction of the plank as well as in the transverse direction of the plank. Although the use of box sections made of molded sheet steel is particularly useful for the manufacture of the planks, other planks, e.g. Planks, gratings or the like assembled from wooden boards are used.
