Description

Die Erfindung betrifft einen Gerüstbelag, gemäß Anspruch 1, wie dieser bei Gerüsten, insbesondere Baugerüsten, als begehbare Arbeitsplattform eingesetzt wird. Darüber hinaus betrifft die Erfindung ein Verfahren, gemäß Anspruch 9, zur Herstellung eines solchen Gerüstbelags.The invention relates to a scaffolding covering, according to claim 1, as used in scaffolding, in particular building scaffolding, as a walk-on work platform. In addition, the invention relates to a method according to claim 9 for producing such a scaffold covering.

Am Markt verfügbare Gerüstbeläge weisen nach einer Bauart einen Tragrahmen aus Längs- und Querprofilen auf, die miteinander verschweißt oder miteinander vernietet sind. Der Tragrahmen besteht zumeist aus Metall und dient der Lagerung und Abstützung einer begehbaren Belagplatte, die beispielsweise aus Holz, Kunststoff oder einem Verbundwerkstoff gefertigt sein kann. Die Belagplatte kann mit dem Tragrahmen verschraubt oder vernietet sein. Derlei Gerüstbeläge werden im Baubereich auch als sogenannte Rahmentafeln oder Kombibeläge bezeichnet. Die Gerüstbeläge sind in der Herstellung kostenintensiv und im Falle einer Beschädigung der Längs- bzw. Querprofile des Tragrahmens nur aufwändig instand zu setzen, zumal hierfür die Belagplatte vom Tragrahmen gelöst und zusätzlich die Niet- oder Schweißverbindungen der Querprofile zerstört werden müssen, um diese zu lösen.Scaffolding decks available on the market have, according to one design, a support frame made of longitudinal and transverse profiles that are welded or riveted to one another. The support frame is mostly made of metal and is used to store and support a decking plate that can be walked on, which can be made of wood, plastic or a composite material, for example. The covering plate can be screwed or riveted to the support frame. Such scaffolding decks are also referred to as so-called frame panels or combination decks in the construction sector. The scaffolding decks are costly to produce and, in the event of damage to the longitudinal or transverse profiles of the support frame, can only be repaired with great effort, especially since the facing plate has to be detached from the support frame and the riveted or welded connections of the transverse profiles must be destroyed in order to loosen them .

Im Stand der Technik ist anhand der DE 93 05 732 U1 ein Bodenelement für eine Bühnenanlage aufgezeigt, das auf einem Rahmen aus Längs- und Querträgern befestigt wird. Im Detail werden die Querträger an einer offenen Seite von J-Profilen der Längsträger eingehängt und über eine aufgelegte Bodenplatte miteinander gehalten. DE 93 05 732 U1 offenbart einen Gerüstbelag gemäß dem Oberbegriff des Anspruchs 1.In the prior art, based on DE 93 05 732 U1 a floor element for a stage system shown, which is attached to a frame made of longitudinal and transverse beams. In detail, the cross members are hung on one open side of J-profiles of the side members and are held together by a floor plate. DE 93 05 732 U1 discloses a scaffolding covering according to the preamble of claim 1.

Es ist deshalb die Aufgabe der Erfindung, einen langlebigen Gerüstbelag anzugeben, der ein für Bauzwecke ausreichend großes Lastaufnahmevermögen aufweist und der dabei einfacher und kostengünstiger zu fertigen ist. Darüber hinaus ist es die Aufgabe der Erfindung, ein kostengünstiges Verfahren zur Herstellung eines solchen Gerüstbelags anzugeben.It is therefore the object of the invention to provide a long-lasting scaffolding covering which has a load-bearing capacity that is sufficiently large for building purposes and which is simpler and cheaper to manufacture. In addition, it is the object of the invention to provide a cost-effective method for producing such a scaffold covering.

Der erfindungsgemäße Gerüstbelag weist die in Anspruch 1 angegebenen Merkmale auf. Das erfindungsgemäße Verfahren ist in Anspruch 9 angegeben.The scaffolding covering according to the invention has the features specified in claim 1. The method according to the invention is specified in claim 9.

Der erfindungsgemäße Gerüstbelag zeichnet sich dadurch aus, dass das bzw. die Querprofile jeweils in die beiden Längsprofile des Tragrahmens eingehakt und alleinig durch die Trag- bzw. Belagplatte in seiner/ihrer in den Längsprofilen eingehakten, d.h. mit den Längsprofilen verhakten, Position gehalten bzw. gesichert ist/sind. Mit anderen Worten wird ein unbeabsichtigtes Lösen der Hakverbindung zwischen dem bzw. den Querprofilen und den Längsprofilen durch die an den beiden Längsprofilen befestigte Belagplatte verhindert bzw. unterbunden. Der erfindungsgemäße Gerüstbelag kann dadurch insgesamt einfacher und kostengünstiger gefertigt werden. Ein Verschweißen oder Vernieten des Querprofils bzw. der einzelnen Querprofile mit den Längsprofilen erübrigt sich vollständig. Insgesamt weist die Belagplatte dadurch eine Doppelfunktion auf. Zum einen verbindet diese die Längsprofile miteinander und ermöglicht dadurch eine ausreichende Biege- und Torsionssteifigkeit des Gerüstbelags. Zum anderen dient sie als Arretier- oder Sicherungsmittel für das mit den Längsprofilen verhakte Querprofil bzw. die mit den Längsprofilen verhakten Querprofile, so dass das Querprofil bzw. die Querprofile gegenüber einem unbeabsichtigten Diskonnektieren von den Längsprofilen gesichert sind. Erfindungsgemäß weist jedes Querprofil zwei Wandschenkel auf, die über einen Rückenabschnitt miteinander verbunden sind. Das bzw. die Querprofile weisen in diesem Fall somit eine im Wesentlichen U-förmige Querschnittsform auf und ist/sind vorzugsweise zur Belagplatte hin offen ausgeführt. Durch eine solche U-förmige Querschnittsform können die Querprofile bei geringer Masse mit einem ausreichend großen Lastaufnahmevermögen realisiert werden. Die beiden Wandschenkel weisen nach der Erfindung, bevorzugt nach außen, abgewinkelte freie Randabschnitte auf, um einen möglichst großen Anlage- bzw. Stützbereich für die Belagplatte zur Verfügung zu stellen.The scaffolding decking according to the invention is characterized in that the transverse profile or profiles are hooked into the two longitudinal profiles of the support frame and are hooked into the longitudinal profiles, ie hooked to the longitudinal profiles, held or held in position solely by the support or covering plate. is / are secured. In other words, unintentional loosening of the hooked connection between the transverse profile or profiles and the longitudinal profiles is prevented or prevented by the facing plate attached to the two longitudinal profiles. The scaffold covering according to the invention can thereby be manufactured more simply and cost-effectively overall. It is completely unnecessary to weld or rivet the transverse profile or the individual transverse profiles to the longitudinal profiles. Overall, the covering plate has a dual function as a result. On the one hand, this connects the longitudinal profiles with one another and thereby enables sufficient flexural and torsional rigidity of the scaffold covering. On the other hand, it serves as a locking or securing means for the transverse profile or the transverse profiles hooked with the longitudinal profiles, so that the transverse profile or the transverse profiles are secured against unintentional disconnection from the longitudinal profiles. According to the invention, each transverse profile has two wall legs which are connected to one another via a back section. In this case, the transverse profile (s) thus have a substantially U-shaped cross-sectional shape and is / are preferably designed to be open towards the facing plate. With such a U-shaped cross-sectional shape, the transverse profiles can be realized with a low mass with a sufficiently large load-bearing capacity. The two According to the invention, wall legs have, preferably outwardly, angled free edge sections in order to provide the largest possible contact or support area for the covering panel.

Nach der Erfindung ist das Lastaufnahmevermögen sowie die Torsionssteifigkeit des Gerüstträgers dadurch nochmals weiter verbessert , dass jedes Querprofil des Tragrahmens beidenends mit jeweils mehreren Haken versehen sind, die in zu den Haken korrespondierende Ausnehmungen der Längsprofile eingreifen.According to the invention, the load-bearing capacity and the torsional rigidity of the scaffold girder are further improved in that each transverse profile of the support frame is provided at both ends with a plurality of hooks which engage in recesses of the longitudinal profiles that correspond to the hooks.

Die Ausnehmungen der Längsträger für den bzw. die Haken des jeweiligen Querprofils sind nach der Erfindung vorzugsweise schlitzförmig ausgeführt. Dadurch kann eine Materialschwächung der Längsträger auf ein Minimum reduziert werden. Auch lassen sich Schlitze ohne großen Aufwand, beispielsweise im Wege eines Laserschneidverfahrens oder mittels einer spanenden Bearbeitung, insbesondere durch Sägen, kostengünstig und mit großer Maßhaltigkeit erzeugen.According to the invention, the recesses of the longitudinal members for the hook or hooks of the respective transverse profile are preferably designed in the shape of a slot. As a result, material weakening of the side members can be reduced to a minimum. Slots can also be produced inexpensively and with great dimensional accuracy without great effort, for example by means of a laser cutting process or by means of machining, in particular by sawing.

Der bzw. die Querträger kann/können mit seinem/ihren Haken vorteilhaft jeweils im Gleitspiel-Formschluss in den Ausnehmungen der Längsträger angeordnet sein. Dadurch kann ein unerwünschtes Verziehen des Tragrahmens bei dessen Herstellung und beim Gebrauch des Gerüstbelags vermieden werden.The cross member (s) can advantageously be arranged with his / her hooks in the recesses of the longitudinal members in a sliding play form fit. As a result, undesired warping of the support frame during its manufacture and when the scaffold covering is used can be avoided.

Die Belagplatte liegt nach der Erfindung vorzugsweise auf einem Profilabsatz der Längsprofile auf. Dadurch können die Längsprofile die Belagplatte im Sinne eines Rahmens im Bereich deren Längskanten seitlich schützend übergreifen. Einer unerwünschten mechanischen Beschädigung der Belagplatte während des Transports oder während des Betriebseinsatzes des Gerüstbelags kann dadurch entgegengewirkt werden.According to the invention, the covering plate preferably rests on a profile shoulder of the longitudinal profiles. As a result, the longitudinal profiles can laterally protectively overlap the facing plate in the area of its longitudinal edges in the sense of a frame. Undesired mechanical damage to the deck slab during transport or when the scaffold deck is in use can thereby be counteracted.

Die Ausnehmungen bzw. die Schlitze der Längsprofile können sich von dem Profilabsatz der Längsprofile bis in einen (innenseitigen) Seitenwandbereich der Längsprofile hinein erstrecken. Dadurch kann das Querprofil bzw. können die Querprofile vereinfacht, ggf. auch zeitgleich, in beide Längsprofile eingehakt werden. Zugleich kann das bzw. können die Querprofile dadurch mit seiner/ihrer Stütz- bzw. Oberfläche zur Abstützung der Belagplatte zu einer, beispielsweise durch den vorstehend genannten Absatz gebildeten, Auflagefläche der Längsprofile fluchtend ausgerichtet werden. Insgesamt kann dadurch eine plane Anlage und Abstützung der Belagplatte an den Längs- sowie auch an dem Querprofil bzw. den Querprofilen erreicht werden.The recesses or the slots of the longitudinal profiles can extend from the profile shoulder of the longitudinal profiles into an (inside) side wall region of the longitudinal profiles. This allows the transverse profile or the Cross profiles are simplified, possibly also at the same time, hooked into both longitudinal profiles. At the same time, the transverse profile (s) can thereby be aligned with its support or surface to support the covering plate with a support surface of the longitudinal profiles, for example formed by the aforementioned paragraph. Overall, a planar contact and support of the facing plate on the longitudinal and also on the transverse profile or the transverse profiles can be achieved.

Nach der Erfindung liegt die Belagplatte auf dem Querprofil bzw. den Querprofilen des Tragrahmens auf. Dadurch kann die Belagplatte im Bereich des Querprofils/der Querprofile (spielfrei) abgestützt werden. Die Belagplatte kann dadurch insgesamt dünner, mithin leichter, bzw. aus einem weniger laststabilen und dadurch kostengünstigeren Material, realisiert werden.According to the invention, the facing plate rests on the transverse profile or the transverse profiles of the support frame. As a result, the covering plate can be supported in the area of the transverse profile (s) (free of play). As a result, the covering plate can be made thinner overall, and consequently lighter, or made from a material that is less load-stable and therefore less expensive.

Die Belagplatte kann nach der Erfindung, vorzugsweise alleinig, mit den Längsprofilen des Tragrahmens vernietet sein. Derlei Nietverbindungen können kostengünstig realisiert werden und bieten nicht zuletzt aufgrund der kostengünstigen Automatisierbarkeit von Nietverfahren - insbesondere bei einer Massenfertigung der Gerüstbeläge - Vorteile.According to the invention, the covering plate can, preferably alone, be riveted to the longitudinal profiles of the support frame. Such rivet connections can be implemented cost-effectively and offer advantages not least because of the cost-effective automation of riveting processes - especially in the case of mass production of the scaffold decks.

Die Längsprofile des Tragrahmens sind nach der Erfindung bevorzugt als Hohlprofile ausgeführt. Dadurch kann ein ausreichendes Lastaufnahmevermögen des Gerüstbelags bei zugleich geringer Masse erreicht werden. Insgesamt ist dies für die Handhabung des Gerüstbelags vorteilhaft.According to the invention, the longitudinal profiles of the support frame are preferably designed as hollow profiles. As a result, the scaffolding covering can be sufficiently loaded with a low mass. Overall, this is advantageous for handling the scaffold deck.

Anspruch 9 offenbart das erfindungsgemäße Verfahren zum Herstellen eines vorstehend erläuterten Gerüstbelags.Claim 9 discloses the method according to the invention for producing a scaffold covering explained above.

Mit dem erfindungsgemäßen Verfahren kann der Gerüstbelag auf einfache und kostengünstige Weise erzeugt werden. Ein Festschweißen bzw. ein zeitraubendes und kostenintensives Befestigen des bzw. er Querprofile an den Längsträgern unter Einsatz von separaten Befestigungsmitteln, wie etwa Schrauben oder Niete, erübrigt sich. Zu beachten ist dabei, dass sich das erfindungsgemäße Verfahren ohne Weiteres automatisieren lässt, sodass die Gerüstbeläge kostengünstig im Wege der Massenfertigung hergestellt werden können. Das Einhaken der Querprofile in die Längsträger kann dabei zeitgleich erfolgen.With the method according to the invention, the scaffolding covering can be produced in a simple and inexpensive manner. There is no need for welding or time-consuming and costly fastening of the transverse profile (s) to the side members using separate fastening means, such as screws or rivets. It should be noted that the method according to the invention can be automated without further ado, so that the scaffolding decks can be manufactured inexpensively by way of mass production. The cross profiles can be hooked into the side members at the same time.

Fig. 1 zeigt einen Gerüstbelag 10 für ein Bau- oder Arbeitsgerüst (nicht gezeigt) in einer schematisierten Unteransicht. Der Gerüstbelag 10 weist eine begehbare Belagplatte 12 auf, die sich entlang der Längsachse 14 des Gerüstbelags 10 erstreckt. Die Belagplatte 12 besteht bevorzugt aus Holz oder einem Holzwerkstoff, kann aber auch aus Kunststoff, einem Verbundwerkstoff oder aus Metall bestehen. Der Gerüstbelag weist einen Tragrahmen auf, der insgesamt mit 16 bezeichnet ist. Der Tragrahmen 16 dient der Abstützung und Aussteifung der Belagplatte 12 sowie der lösbaren Befestigung des Gerüstbelags 10 an anderen Gerüstteilen des Bau- bzw. Arbeitsgerüsts. Der Tragrahmen 16 weist zwei Längsträger bzw. Längsprofile 18 und einen oder mehrere Querträger bzw. Querprofile 20 auf. Die Längsprofile 18 können an ihren freien Endabschnitten 22 jeweils Verbindungsmittel 24 aufweisen, mittels derer der Gerüstbelag 10 in an sich bekannter Weise an vertikal verlaufend angeordneten Gerüststielen bzw. an horizontal verlaufend angeordneten Gerüstriegeln (jeweils nicht gezeigt) befestigbar, beispielsweise einhakbar, ist. Die Längsprofile 18 sind über die Querprofile 20 jeweils miteinander verbunden. Bei dem gezeigten Ausführungsbeispiel weist der Tragrahmen 16 rein beispielhaft vier Querprofile 20 auf. Es versteht sich jedoch, dass der Tragrahmen 16 auch weniger als vier, beispielsweise 2 oder drei, oder auch mehr als vier Querprofile 20 aufweisen kann. Es versteht sich, dass der Gerüstbelag 10 beidenends stirnseitig jeweils mit einem in Fig. 1 mit gestreichelter Linie dargestellten Profilbeschlag 25, bevorzugt aus Metall, versehen sein kann. Der Profilbeschlag 25 kann dabei beidenends an den Längsprofilen 18 befestigt sein und die Verbindungsmittel 24 aufweisen bzw. tragen. Durch einen solchen Profilbeschlag 25 kann bedarfsweise ein stirnseitiger Kantenschutz für die Belagplatte 12 erreicht werden. Fig. 1 shows a scaffold deck 10 for a construction or work scaffolding (not shown) in a schematic view from below. The scaffolding covering 10 has a decking plate 12 which can be walked on and which extends along the longitudinal axis 14 of the scaffolding covering 10. The facing plate 12 is preferably made of wood or a wood material, but can also consist of plastic, a composite material or metal. The scaffolding covering has a support frame, which is designated as a whole by 16 . The support frame 16 is used to support and stiffen the covering plate 12 and to detachably fasten the scaffolding covering 10 to other scaffolding parts of the construction or working scaffolding. The support frame 16 has two longitudinal beams or longitudinal profiles 18 and one or more cross beams or transverse profiles 20 . The longitudinal profiles 18 can each have connecting means 24 at their free end sections 22 , by means of which the scaffolding decking 10 can be fastened, for example hooked, in a manner known per se to vertically arranged scaffolding posts or to horizontally arranged scaffolding bars (each not shown). The longitudinal profiles 18 are each connected to one another via the transverse profiles 20. In the exemplary embodiment shown, the support frame 16 has four transverse profiles, purely by way of example 20 on. It goes without saying, however, that the support frame 16 can also have fewer than four, for example 2 or three, or even more than four transverse profiles 20. It goes without saying that the scaffold covering 10 is provided with an in Fig. 1 with a dashed line profile fitting 25, preferably made of metal, can be provided. The profile fitting 25 can be attached to the longitudinal profiles 18 at both ends and have or carry the connecting means 24. With such a profile fitting 25, an end-face edge protection for the facing plate 12 can be achieved if necessary.

In Fig. 2 ist der Gerüstbelag 10 in einer geschnittenen Detailansicht und in Fig. 3 in einer ausschnittsweisen stirnseitigen Ansicht gezeigt. Die Längsprofile 18 sind jeweils als Hohlprofile ausgeführt und bestehen bevorzugt aus Metall, beispielsweise Aluminium. Die Längsprofile 18 können dabei insbesondere als sogenannte Extrusionsprofile ausgeführt sein. Die Längsprofile 18 weisen jeweils eine Oberseite 26, eine Unterseite 28, eine Außenseite 30 und eine Innenseite 32 auf. Die Oberseite 26 der Längsprofile 18 ist gestuft ausgeführt. Dadurch weisen die Längsprofile 18 jeweils einen Absatz 34 auf. Der Absatz 34 bildet einen Auflagebereich 36 für die Belagplatte 12. Die Belagplatte 12 liegt an dem Auflagebereich 36 unmittelbar an. Die Belagplatte 12 ist hier alleinig an den Längsprofilen 18 befestigt und über mehrere Niete 38 (Fig. 3) mit den Längsprofilen (alleinig) vernietet. Die Niete 38 eines Längsprofils 18 sind in axialer Richtung voneinander beabstandet angeordnet. Dadurch ist die Belagplatte 12 an den Längsprofilen 18 des Tragrahmens 16 dauerhaft lagefixiert gehalten. Der Auflagebereich 36 kann mehrere stegartige Erhebungen bzw. Riffel 39 aufweisen, dies jeweils axial verlaufend angeordnet sind. Die Riffel sind zueinander seitlich versetzt angeordnet und dienen einer rutsch- und wackelfesten Auflage der Belagplatte 12 am Längsprofil 18 und krallen sich dazu vorzugsweise in das Material der Belagplatte 12 ein.In Fig. 2 is the scaffolding deck 10 in a cut detailed view and in Fig. 3 shown in a fragmentary front view. The longitudinal profiles 18 are each designed as hollow profiles and are preferably made of metal, for example aluminum. The longitudinal profiles 18 can in particular be designed as so-called extrusion profiles. The longitudinal profiles 18 each have an upper side 26, a lower side 28, an outer side 30 and an inner side 32 . The top 26 of the longitudinal profiles 18 is designed stepped. As a result, the longitudinal profiles 18 each have a shoulder 34 . The shoulder 34 forms a support area 36 for the covering plate 12. The covering plate 12 rests directly on the supporting area 36. The facing plate 12 is here attached solely to the longitudinal profiles 18 and is secured by several rivets 38 ( Fig. 3 ) riveted to the longitudinal profiles (solely). The rivets 38 of a longitudinal profile 18 are arranged at a distance from one another in the axial direction. As a result, the covering plate 12 is held in a permanently fixed position on the longitudinal profiles 18 of the support frame 16. The support area 36 can have several web-like elevations or corrugations 39 , each of which is arranged to run axially. The corrugations are arranged laterally offset to one another and serve as a non-slip and wobbly support of the facing plate 12 on the longitudinal profile 18 and, for this purpose, preferably claw into the material of the facing plate 12.

Die Querprofile 20 weisen jeweils beidenends mehrere Haken 40 auf, über die die Querprofile 20 mit den beiden Längsprofilen 18 verhakt sind.The transverse profiles 20 each have several hooks 40 at both ends, via which the transverse profiles 20 are hooked to the two longitudinal profiles 18.

Die Haken 40 sind in der in Fig. 4 gezeigten freigestellten Detailansicht eines einzelnen Querprofils 20 des Tragrahmens 16 (Fig. 1) gut zu erkennen. Die Haken 40 sind am Querprofil 20 angeformt und vorzugsweise baugleich ausgeführt. Dadurch, dass die Haken 40 - bezogen auf die Längsachse 14 des Gerüstbelags 10 (Fig. 1) - in axialer Richtung mit einem Abstand A voneinander beabstandet am jeweiligen Querprofil 20 angeordnet sind, kann eine besonders laststabile und verwindungssteife Verbindung zwischen den Querprofilen 20 und den Längsträgern 18 erreicht werden. Die Querprofile 20 weisen jeweils eine U-förmige Querschnittsform auf. Zwei zueinander parallel oder im Wesentlichen parallel verlaufend angeordnete Wandschenkel 42 sind über einen Verbindungs- oder Rückenabschnitt 44 der Querprofile 20 miteinander verbunden. Zu beachten ist, dass die beiden Wandschenkel 42 nach außen abgewinkelte bzw. gebogene freie Randabschnitte 46 aufweisen können. Die Belagplatte (Fign. 1 bis 3) des Gerüstbelags 10 kann dadurch zusätzlich an der der Belagplatte 12 zuweisenden Stütz- bzw. Oberfläche 48 der Randabschnitte 46 der Querprofile 20 großflächig abgestützt werden. Die Oberflächen 48 der Wandschenkel 42 der Querprofile 20 fluchten jeweils mit dem Auflagebereich 36 der Längsprofile 18 (Fig. 3) in einer zur Längsachse 14 des Gerüstbelags 10 (Fig. 1) orthogonal verlaufenden Richtung.The hooks 40 are in the Fig. 4 shown cut-out detailed view of a single transverse profile 20 of the support frame 16 ( Fig. 1 ) clearly visible. The hooks 40 are formed on the transverse profile 20 and are preferably constructed identically. The fact that the hooks 40 - based on the longitudinal axis 14 of the scaffolding deck 10 ( Fig. 1 ) - are arranged at a distance A from one another in the axial direction on the respective transverse profile 20, a particularly load-stable and torsion-resistant connection between the transverse profiles 20 and the longitudinal members 18 can be achieved. The transverse profiles 20 each have a U-shaped cross-sectional shape. Two wall legs 42 which are arranged parallel or essentially parallel to one another are connected to one another via a connecting or back section 44 of the transverse profiles 20. It should be noted that the two wall legs 42 can have free edge sections 46 which are angled or curved outward. The deck plate ( Figs. 1 to 3 ) of the scaffold covering 10 can thereby additionally be supported over a large area on the supporting or surface 48 of the edge sections 46 of the transverse profiles 20 facing the covering plate 12. The surfaces 48 of the wall legs 42 of the transverse profiles 20 are each aligned with the support area 36 of the longitudinal profiles 18 ( Fig. 3 ) in one to the longitudinal axis 14 of the scaffolding deck 10 ( Fig. 1 ) orthogonal direction.

Zwischen dem Haken 40 und dem jeweilig zugeordneten Wandschenkel 42 ist eine Nut 50 mit einer Breite B ausgebildet.A groove 50 with a width B is formed between the hook 40 and the respectively assigned wall leg 42.

In Fig. 5 ist eines der Längsprofile 18 des Tragrahmens 16 des Gerüstbelags 10 gemäß Fig. 1 in einem freigestellten perspektivischen Detailausschnitt gezeigt. Das Längsprofil 18 weist mehrere schlitzförmige Ausnehmungen 52 auf, um so einen Eingriff der Haken 40 der Querprofile 20 zu ermöglichen. Die Ausnehmungen 52 sind am jeweiligen Längsprofil 18 paarweise gruppiert angeordnet und weisen einen zum Abstand A der Haken 40 (Fig. 4) entsprechenden Abstand A auf. Die Ausnehmungen 52 durchgreifen dabei jeweils die Wandung 54 der Längsprofile 18. Die Ausnehmungen 52 erstrecken sich hier jeweils vom oberseitigen Auflagebereich 36 der Längsprofile 18 quer zur Längsachse 14 in die Innenseite 32 des Längsprofils 18 hinein. Dadurch können die Querprofile 20 bei der Montage des Gerüstbelags 10 (Fig. 1) vereinfacht mit den Haken 40 in die Ausnehmungen mit den Längsprofilen 18 eingehakt werden. Die Wandung 54 der Längsprofile 18 greift dabei jeweils in eine der in Fig. 4 gezeigten Nuten 50 des jeweiligen Querprofile 20 ein. Die Breite B der Nut ist dabei vorzugsweise auf die Materialstärke (in der Zeichnung nicht bezeichnet) der Wandung 54 abgestimmt, um in axialer Richtung bezogen auf die Längsachse 14 (Fig. 1) eine spielarme bzw. formschlüssige Halterung der Querprofile 20 an den beiden Längsprofilen 18 zu ermöglichen. Die Ausnehmungen 52 können im Wege eines Laserschneidverfahrens oder auch rein spanend, etwa durch Sägen, erzeugt sein.In Fig. 5 is one of the longitudinal profiles 18 of the support frame 16 of the scaffold deck 10 according to Fig. 1 shown in a cut-out perspective detail. The longitudinal profile 18 has a plurality of slot-shaped recesses 52 in order to enable the hooks 40 of the transverse profiles 20 to engage. The recesses 52 are arranged in pairs on the respective longitudinal profile 18 and have a spacing A of the hooks 40 ( Fig. 4 ) corresponding distance A. The recesses 52 each extend through the wall 54 of the longitudinal profiles 18. The recesses 52 here each extend from the upper-side support area 36 of the longitudinal profiles 18 transversely to the Longitudinal axis 14 into the inside 32 of the longitudinal profile 18. As a result, the transverse profiles 20 can be used when assembling the scaffolding deck 10 ( Fig. 1 ) are hooked into the recesses with the longitudinal profiles 18 using the hooks 40. The wall 54 of the longitudinal profiles 18 engages in each of the in Fig. 4 shown grooves 50 of the respective transverse profile 20. The width B of the groove is preferably matched to the material thickness (not shown in the drawing) of the wall 54 in order to be able to move in the axial direction with respect to the longitudinal axis Fig. 1 ) to enable a low-play or form-fitting mounting of the transverse profiles 20 on the two longitudinal profiles 18. The recesses 52 can be produced by means of a laser cutting process or also purely by cutting, for example by sawing.

Die Querprofile 20 des Tragrahmens sind gegenüber einem Diskonnektieren von den Längsträgern 18 alleinig durch die mit den Längsträgern 18 unmittelbar festgenietete Belagplatte 12 gesichert. Dadurch erübrigt sich ein zeit- und kostenintensives Vernieten oder Verschweißen jedes einzelnen Querprofils 20 mit den Längsprofilen 18.The transverse profiles 20 of the support frame are secured against disconnection from the longitudinal beams 18 solely by the facing plate 12 riveted directly to the longitudinal beams 18. This eliminates the need for time-consuming and costly riveting or welding of each individual transverse profile 20 to the longitudinal profiles 18.

Im Falle einer Beschädigung eines oder mehrerer Querprofile 20 bzw. Längsprofile 18 des Tragrahmens 16 (Fig. 1) müssen somit nur die Nietverbindungen zwischen der Belagplatte und den Längsträgern (zerstörend) gelöst und die Belagplatte 12 vom Tragrahmen 16 abgehoben werden, um die betroffenen Profile des Tragrahmens 16 austauschen zu können. Der in der vorstehend beschriebenen Weise aufgebaute Gerüstbelag 10 ist dadurch besonders einfach und kostengünstig herzustellen und zu reparieren.In the event of damage to one or more transverse profiles 20 or longitudinal profiles 18 of the support frame 16 ( Fig. 1 ) thus only the riveted connections between the facing plate and the side members have to be loosened (destructively) and the facing plate 12 lifted off the support frame 16 in order to be able to exchange the affected profiles of the support frame 16. The scaffolding deck 10 constructed in the manner described above is particularly simple and inexpensive to manufacture and repair.

Nachfolgend wird das erfindungsgemäße Verfahren zur Herstellung des vorstehend erläuterten Gerüstbelags 10 unter zusätzlicher Bezugnahme auf Fig. 6 erläutert.The method according to the invention for producing the scaffold covering 10 explained above is described below with additional reference to FIG Fig. 6 explained.

In einem ersten Schritt 102 werden die Längs- und Querprofile 18, 20 (Fig. 1) sowie die Belagplatte 12 bereitgestellt. In Schritt 104 werden die Querprofile 20 in die Längsprofile 18 unter Bildung des Tragrahmens 16 (Fig. 1) eingehakt. In Schritt 106 wird die Belagplatte 12 auf die Längsprofile 18 des Tragrahmens 16 aufgelegt und in Schritt 108 die Querprofile in ihrer in die Längsprofile eingehakten Position gesichert, indem die Belagplatte an den Längsprofilen 18 befestigt, insbesondere mit diesen vernietet, wird.In a first step 102 , the longitudinal and transverse profiles 18, 20 ( Fig. 1 ) and the facing plate 12 provided. In step 104 , the transverse profiles 20 are inserted into the longitudinal profiles 18 to form the support frame 16 ( Fig. 1 ) hooked. In In step 106 the covering plate 12 is placed on the longitudinal profiles 18 of the support frame 16 and in step 108 the transverse profiles are secured in their position hooked into the longitudinal profiles by attaching the covering plate to the longitudinal profiles 18, in particular riveting them.
