Abstract

PCT No. PCT/EP95/01970 Sec. 371 Date Dec. 30, 1996 Sec. 102(e) Date Dec. 30, 1996 PCT Filed May 24, 1995 PCT Pub. No. WO96/01350 PCT Pub. Date Jan. 18, 1996Platform units for scaffolding must be light and strong in design and be usable without risk of accident. Therefore, all their parts are designed for a long service life, and should also be included in the static analysis. High rigidity of the corner joints of the rectangular support frame for the platform unit is thereby advantageous as well as having the narrowest possible gaps between adjacent platform units. The invention uses for this purpose, a three-dimensional arrangement of the mounting brackets on the support frames, which combine relative structural symmetry with the fact that the mounting brackets are offset, and thus permit a narrow gap formation between the platform units. The corner joints of the support frames are, in spite of their light construction, resistant to distortion and any uncertainty due to the use of wooden planks for the floor surface is avoided by using a friendly holding frame.

Description

Belagbühne Topping platform
Beschreibungdescription
Die Erfindung betrifft eine Belagbühne für ein Baugerüst oder dergleichen, die in zwei waagerechte Querholme des Baugerüstes einhängbar ist, bestehend aus mindestens einem rechteckigen, aus Längs- und Querträgern zusammengesetzten Tragrahmen (dessen von den Querträgern gebildete Stirnsei¬ ten jeweils denjenigen eines weiteren Tragrahmenε parallel benachbart sind) , einem auf dem Tragrahmen vorgesehenen, als Lauffläche dienenden plattenförmigen Belag und min- destens zwei an jeder Stirnseite des Tragrahmens an den Querträgern befestigten, die Querholme des Baugerüsts über¬ fangenden, hakenförmigen Halterungen.The invention relates to a covering platform for scaffolding or the like, which can be suspended in two horizontal crossbars of the scaffolding, consisting of at least one rectangular support frame composed of longitudinal and cross members (the end faces formed by the cross members are each adjacent to that of a further supporting frame in parallel ), a plate-shaped covering provided on the support frame, serving as a tread, and at least two hook-shaped holders fastened to the crossbeams on each end face of the support frame and overlapping the crossbars of the scaffolding.
Eine Belagbühne dieser Art ist beispielsweise aus der Pa¬ tentschrift EP 0 451 616 Bl bereits bekannt. Dabei wird der Querholm durch ein nach oben offenes U-Profil gebildet, in dessen beide senkrechte Stege die Halterungen des an den betreffenden Steg angrenzenden Tragrahmens eingehängt wer¬ den können. Eine solche Anordnung hat den Nachteil, daß zwischen benachbarten Tragrahmen relativ breite Lücken ver- bleiben, die während der Benutzung der Belagbühne eine er¬ hebliche Unfallgefahr (Stolpern) darstellen: der Querholm selbst ist nicht abgedeckt, und zwischen dem Querholm und den Tragrahmen verbleiben freie Abstände durch die Ausge- staltung der Halterungen. Der waagerechte Gurt des als Querholm dienenden U-Profils kann dabei nicht beliebig ge¬ kürzt werden, weil die Haken der Halterungen genügend sta¬ bil sein müssen und entsprechenden Platz zwischen den Ste- gen erfordern.A covering platform of this type is already known, for example, from patent specification EP 0 451 616 B1. The cross member is formed by an upwardly open U-profile, in the two vertical webs of which the holders of the supporting frame adjacent to the web in question can be hung. Such an arrangement has the disadvantage that relatively wide gaps remain between adjacent support frames, which pose a considerable risk of accident (stumbling) during use of the covering platform: the cross member itself is not covered, and free spaces remain between the cross member and the support frame Distances through the design of the brackets. The horizontal belt of the U-profile serving as a cross member cannot be shortened arbitrarily because the hooks of the brackets must be sufficiently stable and require appropriate space between the webs.
Die Halterungen sind bei der vorbekannten Ausführung in das Innere der als stranggepreßte, im Querschnitt etwa recht¬ eckige Hohlprofile ausgebildete Längsträger gezogen und dort an einem senkrechten Steg dieses Hohlprofiles vernie- tet; eine an dem betreffenden Querträger mittig vorgesehene Halterung ist - anders gestaltet - stattdessen an dem Quer¬ träger angeschweißt. Die baulich komplizierte Ausbildung ist erforderlich, weil die Querträger an den inneren Stegen der Längsträger angeschweißt sind und diese deshalb stirn- εeitig offen bleiben.In the known design, the holders are drawn into the interior of the longitudinal beams, which are designed as extruded, hollow cross-sections which are approximately rectangular in cross-section, and riveted there to a vertical web of this hollow profile; a holder provided in the center of the cross member in question is - welded differently - instead welded to the cross member. The structurally complicated design is necessary because the cross members are welded to the inner webs of the side members and therefore they remain open at the end.
Bei derartigen Belagbühnen ist der jeweilige Tragrahmen mit einem plattenför igen Belag ausgerüstet, der im allgemeinen - wie auch bei der beschriebenen vorbekannten Ausführung - aus einem verleimtem Sperrholz besteht und mit dem Tragrah- men vernietet ist. Die hohe Lochleibung während der Benut¬ zung der Belagbühne führt mit der Zeit zur Vergrößerung der Niet-Bohrungen im Sperrholz, so daß der Belag keinen Bei¬ trag zur Steifigkeit der Belagbühne zu leisten vermag und bei deren statischer Berechnung unberücksichtigt bleibt. Die wenn auch nur geringe zunehmende Verschiebbarkeit des Belages auf dem Tragrahmen trägt darüberhinauε zur Vermin¬ derung der Trittsicherheit während der Benutzung der Belag¬ bühne bei.In such covering platforms, the respective supporting frame is equipped with a plate-shaped covering which, in general - as in the previously known embodiment described - consists of a glued plywood and is riveted to the supporting frame. The high perforation during the use of the covering platform leads over time to the enlargement of the rivet holes in the plywood, so that the covering cannot make any contribution to the rigidity of the covering platform and is not taken into account in its structural calculation. The increasing, if only slight, displaceability of the covering on the supporting frame furthermore contributes to a reduction in the surefootedness during use of the covering platform.
Die Erfindung hat sich deshalb die Aufgabe gestellt, eine Belagbühne der eingangs näher bezeichneten Art mit einfa¬ chen Mitteln betriebssicherer zu gestalten und darüber hin¬ aus so auszubilden, daß der Belag die Steifigkeit der Be¬ lagbühne auf Dauer verbessert und in die statische Be¬ rechnung einbezogen werden kann. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die einander zugeordneten Halterungen an den gegenüberliegenden Stirnseiten jeweils seitlich versetzt zu einer Ebene paral¬ lel zu den Längsträgern angeordnet sind. Bei einer solchen Anordnung läßt es sich bequem einrichten, daß die Halterun¬ gen benachbarter Tragrahmen nicht aneinanderstoßen können und die Lücke zwischen den Tragrahmen und insbesondere de¬ ren plattenförmigen Belägen nur noch von der längsseitigen Ausdehnung einer Halterung bestimmt ist und damit so klein gehalten werden kann, daß sie bei der Benutzung der Belag¬ bühne praktisch nicht mehr wahrgenommen wird.The object of the invention is therefore to make a covering platform of the type specified in the introduction more reliable with simple means and, moreover, to design it in such a way that the covering permanently improves the rigidity of the covering platform and into the static loading invoice can be included. According to the invention, the object is achieved in that the mutually associated mounts on the opposite end faces are each laterally offset to a plane parallel to the longitudinal beams. With such an arrangement, it can be conveniently set up that the holders of adjacent support frames cannot abut one another and that the gap between the support frames and in particular their plate-shaped coverings is determined only by the longitudinal extension of a holder and can thus be kept so small that it is practically no longer perceived when using the covering platform.
Besonders praktisch ist es, wenn die Halterungen an den Querträgern paarweise und in der Nähe der Längsträger vor¬ gesehen sind, wobei sie an den Querträgern des gleichen Tragrahmens so angeordnet sein können, daß die diagonal an dem Tragrahmen befindlichen Halterungen paarweise den je¬ weils gleichen Abstand von der jeweils benachbarten Längs¬ seite haben. Trotz der an sich unsymmetrischen Ausbildung der Anordnung ist auf diese Weise sichergestellt, daß eh- rere Belagbühnen übereinander gestapelt werden können und dabei die Halterungen jeweils genau übereinander zu liegen kommen, ohne daß auf die Orientierung der Belagbühnen ge¬ achtet werden müßte.It is particularly practical if the brackets on the cross members are provided in pairs and in the vicinity of the longitudinal members, and they can be arranged on the cross members of the same support frame in such a way that the brackets located diagonally on the support frame are identical in pairs Have a distance from the respectively adjacent longitudinal side. In spite of the asymmetrical configuration of the arrangement, it is ensured in this way that your covering platforms can be stacked on top of each other and the brackets come to lie exactly one above the other without having to pay attention to the orientation of the covering platforms.
Es ist zweckmäßig, wenn die beiden Abstände der Halterungen ein und desselben Querträgers von der der jeweiligen Halte¬ rung benachbarten Längsseite um mindestens die - in der zu den Stirnseiten parallelen Richtung gemessene - Dicke der Halterung differieren, diesen Betrag dabei aber eben mög¬ lichst wenig überschreitend, so daß die Belastung der Be- läge möglichst unmittelbar in die Längsträger überführt wird, insbesondere beispielsweise auch dadurch, daß zwei diagonal an dem Tragrahmen befindliche Halterungen bündig zu den jeweiligen Längsseiten vorgesehen sind, so daß die komplementären Halterungen nicht zu weit nach innen gezogen werden müssen. In einer besonders bevorzugten Ausführung der Erfindung be¬ stehen die Querträger und/oder die Längstrager aus einem vorzugsweise stranggepreßten, im Querschnitt etwa recht¬ eckigen Hohlprofil, das aus je zwei jeweils parallelen senkrechten Stegen und waagerechten Gurten zusammengesetzt ist. Eine solche kastenförmige Ausbildung der Längs¬ und/oder Querträger führt zu einer verwindungsfreien Aus¬ bildung des Tragrahmens, insbesondere, wenn an dessen Eck¬ knoten der innere Steg des Längsträgers in der Breite des dort anschließenden Querträgers ausgeschnitten und min¬ destens die Stege des Querträgers bis zum äußeren Steg des Längsträgers durchgeführt und an den Gurten und/oder Stegen des Längsträgers angeschweißt sind. Ein solcher Eckknoten ist auf diese Weise sehr robust ausgebildet und hoch be- lastbar; außerdem hat eine derartige Konstruktion den Vor¬ teil, daß die Stirnseiten des Tragrahmens wie schon dessen Längsseiten jeweils geschlossene Flächen bilden. Im einzeln kann man dabei so vorgehen, daß die Höhe der Querträger diejenige der Längsträger um die Dicke von deren Gurten unterschreitet; in diesem Fall ist es auch möglich, daß der gesamte Querträger bis zu dem äußeren Steg des Längsträgers durchgeführt ist, also einschließlich seiner Gurte, die dann für eine Verschraubung oder Vernietung mit dem Längs¬ träger und dem Belag zur Verfügung stehen.It is expedient if the two distances between the holders of one and the same cross member differ from the longitudinal side adjacent to the respective holder by at least the thickness of the holder, measured in the direction parallel to the end faces, but this amount is as little as possible exceeding, so that the loading of the coverings is transferred as directly as possible into the side members, in particular, for example, also in that two brackets located diagonally on the support frame are provided flush with the respective longitudinal sides, so that the complementary holders are not pulled too far inwards Need to become. In a particularly preferred embodiment of the invention, the cross members and / or the longitudinal members consist of a preferably extruded hollow profile which is approximately rectangular in cross section and which is composed of two parallel vertical webs and horizontal belts. Such a box-shaped design of the longitudinal and / or transverse beams leads to a torsion-free formation of the supporting frame, in particular if the inner web of the longitudinal beam is cut out at the corner knot in the width of the subsequent transverse beam and at least the webs of the transverse beam to the outer web of the side member and are welded to the belts and / or webs of the side member. In this way, such a corner knot is designed to be very robust and highly resilient; In addition, such a construction has the advantage that the end faces of the support frame, like the longitudinal sides thereof, each form closed surfaces. In detail, one can proceed in such a way that the height of the crossbeams falls below that of the longitudinal beams by the thickness of their belts; in this case it is also possible for the entire cross member to be carried out as far as the outer web of the side member, that is to say including its belts, which are then available for screwing or riveting to the side member and the covering.
Zur seitlichen Arretierung dieses Belages und als Stapel¬ hilfe können an den Gurten der Längsträger längsseitig des Tragrahmens Führungsrippen derart ausgebildet sein, daß de¬ ren Höhe die Höhe des auf den Gurten aufliegenden Belages unterschreitet, wobei die Höhe der Führungsrippen über dem zugehörigen Gurt vorzugsweise etwa die Hälfte der Höhe des Belages beträgt, so daß die halbe Höhe der Führungsrippen zur Arretierung des Belages und die andere Hälfte als Sta¬ pelhilfe dient, die in die entsprechende Kanten-Lücke eines darüber oder darunter befindlichen weiteren Tragrahmens eingreift. - 5For lateral locking of this covering and as a stacking aid, guide ribs can be formed on the straps of the longitudinal members along the side of the support frame in such a way that their height falls below the height of the covering resting on the straps, the height of the guide ribs above the associated belt preferably being approximately is half the height of the covering, so that half the height of the guide ribs for locking the covering and the other half serves as a stacking aid which engages in the corresponding edge gap of a further support frame located above or below. - 5th
Es ist besonders vorteilhaft, wenn die Halterungen an den Querträgern des Tragrahmens angeschweißt sind, dessen Stirnseiten dafür in ganzer Breite zur Verfügung stehen können. Ein Rückgriff auf die Längsträger ist nicht mehr erforderlich, so daß die Anbringung der Halterungen außer¬ ordentlich einfach ist.It is particularly advantageous if the brackets are welded to the cross members of the support frame, the end faces of which can be available in full width for this. It is no longer necessary to resort to the side members, so that the mounting of the brackets is extremely simple.
Eine dauerhafte Formstabilität des Tragrahmens wird unter¬ stützt, wenn der Belag aus Holzplatten, insbesondere aus Sperrholzplatten, zusammengesetzt ist, die von einem den gesamten Belag umlaufenden, vorzugsweise aber allein die auf den Längsträgern aufliegenden Seiten des Belages erfas¬ senden, auf den Gurten des Tragrahmens aufliegenden metal¬ lischen Halterahmen gefaßt sind, besonders wenn dabei der Belag an seinem Halterahmen mittels Verbindungselementen mit dem Tragrahmen verbunden, vorzugsweise vernietet ist. Der Halterahmen ist weniger als die Holzplatten von blei¬ bender Verformung in den Bohrungen für die Verbindungsele¬ mente bedroht, so daß verschleißbedingte Lockerungen im Be¬ reich dieser Verbindungselemente auch bei hoher Belastung der Belagbühne vermieden werden könne.A permanent form stability of the support frame is supported if the covering is composed of wooden panels, in particular of plywood panels, which transmit from one side of the covering that encircles the entire covering, but preferably only the sides lying on the longitudinal beams, on the belts of the Metallische holding frame lying on the supporting frame are gripped, especially if the covering on its holding frame is connected to the supporting frame by means of connecting elements, preferably riveted. The holding frame is less threatened by permanent deformation in the bores for the connecting elements than the wooden plates, so that loosening due to wear in the area of these connecting elements can be avoided even when the covering platform is subjected to high loads.
Um einen Durchstieg durch die Belagbühne zu ermöglichen, ist es günstig, wenn mindestens ein Teil des Belages als Klappe ausgebildet und um eine zu einem Längsträger paral¬ lele, an diesem ortsfeste Achse schwenkbar ist; die Klappe ist besonders dann hoch belastbar, wenn sie mit einem Teil ihrer Berandung auf einem Querträger aufliegt. Es ist zweckmäßig, wenn die Achse von Scharnierstücken gebildet wird, die an dem Längsträger befestigt sind. Selbstver¬ ständlich erfordert die Klappe in bekannter Weise eine Auf- lageleiste, wenn ein Teil ihrer Berandung anders nicht un¬ terfangen wäre.In order to make it possible to climb through the covering platform, it is advantageous if at least part of the covering is designed as a flap and can be pivoted about an axis parallel to a longitudinal beam and fixed on the latter; the flap is particularly resilient when it rests with part of its edge on a cross member. It is expedient if the axis is formed by hinge pieces which are attached to the side member. Of course, the flap requires, in a known manner, a support ledge if part of its border would not have been otherwise.
Insgesamt ist eine erfindungsgemäße Belagbühne mit einer hohen Arbeitssicherheit und langer Lebensdauer verbunden, kann dabei aber sehr leicht ausgebildet werden, weil auch der Belag in die statische Berechnung einbezogen werden kann.Overall, a covering platform according to the invention is associated with a high level of occupational safety and a long service life, but it can be designed very easily because also the covering can be included in the static calculation.

Fig. 13 einen Stapel mehrerer erfindungsgemäßer Belagbüh- nen, sämtlich in schematisch vereinfachter Dar¬ stellung. In der Fig. 1 ist eine erfindungsgemäße rechteckige Belag¬ bühne in der Übersicht dargestellt, in der bereits deren Zusammensetzung aus einem Tragrahmen 1 und einem platten- förmigen Belag 2 zu erkennen ist. Auch vier Halterungen 3 sind zu erkennen, die in der Nähe der vier Eckknoten E des Tragrahmens 1 an dessen Stirnseiten S angebracht sind. In der Fig. 2 ist zu erkennen, daß die Halterungen 3 hakenför¬ mig ausgebildet und unmittelbar an den Stirnseiten S befe¬ stigt sind, die sich bis zu den beiden Längsseiten L er- strecken. Die Stirn- und Längsseiten S,L des Tragrahmens 1 werden von Querträgern 11 und Längsträgern 12 gebildet, wie sie zunächst aus Fig. 3 und 4 ersichtlich sind.13 shows a stack of a plurality of covering platforms according to the invention, all in a schematically simplified illustration. 1 shows an overview of a rectangular covering platform according to the invention, in which the composition of which already consists of a support frame 1 and a plate-shaped covering 2 can be seen. Four brackets 3 can also be seen, which are attached in the vicinity of the four corner nodes E of the support frame 1 on its end faces S. It can be seen in FIG. 2 that the brackets 3 are hook-shaped and are attached directly to the end faces S which extend up to the two long sides L. The front and longitudinal sides S, L of the support frame 1 are formed by cross members 11 and longitudinal members 12, as can first be seen in FIGS. 3 and 4.
In der Fig. 4 ist zu erkennen, daß die Halterungen 3 in Ab¬ ständen a,b von den Längsseiten vorgesehen sind, die an je- weils diagonal gegenüberliegenden Eckknoten E gleich, an ein und demselben Querträger 11 aber verschieden sind: die im Abstand a von der Längsseite L befestigten Halterungen 3 sind etwa bündig mit dieser Längsseite L, die in dem größe¬ ren Abstand b befindlichen hingegen soweit von der Längs- seite L abgerückt, daß die Halterungen 3 bei in Reihe fluchtenden Belagbühnen an dem gleichen Querholm eines Bau¬ gerüstes von beiden Seiten aus einhängbar sind und neben¬ einander zu liegen kommen, so daß die verbleibende Lücke zwischen den benachbarten Belagbühnen nicht wesentlich größer gehalten werden muß als es der Länge 1 der Halterun¬ gen 3 (Fig. 4) entspricht. Die Differenz der Abstände a,b ist etwas größer als die Dicke d der Halterungen 3 (Fig. 2), um ein Verklemmen zweier auf dem gleichen Querholm be¬ nachbarter Halterungen 3 mit Sicherheit zu vermeiden.4 that the brackets 3 are provided at distances a, b from the long sides, which are the same at diagonally opposite corner nodes E, but different on one and the same cross member 11: those at a distance a from the long side L fastened brackets 3 are approximately flush with this long side L, the ones located at the greater distance b, on the other hand, moved so far from the long side L that the brackets 3 are aligned with the deck platforms in series on the same cross member of a building ¬ scaffolding can be hung from both sides and come to lie next to each other, so that the remaining gap between the adjacent covering platforms does not have to be kept much larger than corresponds to the length 1 of the brackets 3 (FIG. 4). The difference between the distances a, b is somewhat larger than the thickness d of the brackets 3 (FIG. 2) in order to reliably avoid jamming of two brackets 3 neighboring on the same cross member.
In den Fig. 5 und 6 ist zu erkennen, daß die Längsträger 12 aus einem im Strangpreßverfahren herstellbaren, im Quer¬ schnitt im wesentlichen rechteckigen Hohlprofil bestehen, das sich aus je zwei parallelen senkrechten Stegen 12a und 12b und zwei waagrechten, jedoch nicht durchgehenden, eben- falls parallelen Gurten 12c zusammensetzt, so daß die Längsträger 12 balkenartig ausgebildet sind. Auf den Gurten 12c bzw. anstelle eines Teils der Gurte 12c befinden sich bündig mit den Längsseiten L und in deren ganzer Länge Füh¬ rungsrippen 12d zur primären Lagesicherung des Belages 2 in der Richtung R parallel zu den Querträgern 11. Die von den Führungsrippen 12d auf den Gurten 12c freibleibende Fläche dient als Auflager für den Belag 2; dabei reicht die Höhe h der ihrerseits im Querschnitt rechteckig ausgebildeten Füh¬ rungsrippen 12d etwa bis zu der halben Höhe H des Belages 2, so daß die Führungsrippen 12d auf diese Weise auch als Stapelhilfe verwendbar sind; in der Fig. 13 ist gezeigt, daß sie aufeinanderliegend und die Beläge 2 einschließend eine Verschiebung der aufeinanderliegenden Belagbühnen in der Richtung R (Fig. 6) sicher verhindern.5 and 6 it can be seen that the longitudinal beams 12 consist of a hollow profile which is essentially rectangular in cross-section and which can be produced by extrusion and which consists of two parallel vertical webs 12a and 12b and two horizontal, but not continuous, also assembles parallel belts 12c so that the The longitudinal beams 12 are designed like bars. On the belts 12c or instead of part of the belts 12c there are guide ribs 12d flush with the longitudinal sides L and along their entire length for the primary securing of the position of the covering 2 in the direction R parallel to the cross members 11. Those of the guide ribs 12d the straps 12c free surface serves as a support for the covering 2; the height h of the guide ribs 12d, which in turn have a rectangular cross section, extends approximately to half the height H of the covering 2, so that the guide ribs 12d can also be used in this way as a stacking aid; in FIG. 13 it is shown that they lie on top of one another and the coverings 2 including reliably prevent displacement of the coverings platforms lying on top of one another in the direction R (FIG. 6).
In den Fig. 5 und 6 ist ferner zu sehen, daß die Querträger 11 in den Eckknoten E in die Längsträger 12 eingreifen; die dazu näheren Einzelheiten sind in der Fig. 7 ausführlich dargestellt. Dort ist deutlich gemacht, daß der innere Steg 12b des Längsträgerε 12 an seinem Ende in einer Breite B ausgeklinkt und das Ende des Querträgers 11 in den Längε- träger 12 εoweit eingeführt iεt, daß eε an deεεen äußerem Steg 12a anεchlägt. Der Querträger 11 ist ebenfalls ein im Strangpreßverfahren hergestelltes, im Querschnitt recht¬ eckiges Hohlprofil, wie das aus der Fig. 11 abgelesen wer- den kann. Seine Höhe HQ ist gegenüber der Höhe HL des Längsträgers 12 um etwa die doppelte Dicke DL eines Gurteε 12c des Längsträgers 12 vermindert, so daß er mit seinen Gurten 11c an den Gurten 12c mit Spiel anliegt. Es ist deε- halb ohne Schwierigkeit möglich, die Gurte llc und 12c mit- einander in dem εich überschneidenden Bereich zu ver¬ schweißen, ebenso wie einen inneren Steg 11b des Querträ¬ gers 11 mit dem inneren Steg 12b des Längsträgers 12; auch der Stoß der beiden äußeren Stege lla und 12a kann leicht so ausgebildet werden, daß dort eine Schweißnaht vorgesehen werden kann. Auf diese Weise lassen sich die Eckknoten E außerordentlich formstabil ausführen, obwohl jeweils eine volle Stirnfläche S gewährleiεtet ist. An dieser Stirnflä¬ che S sind die hakenförmigen Halterungen 2 befestigt; sie sind ebenfalls angeschweißt.5 and 6 it can also be seen that the cross members 11 engage in the corner knot E in the longitudinal members 12; the details of this are shown in detail in FIG. 7. It is made clear there that the inner web 12b of the longitudinal member 12 is notched at a width B at its end and the end of the cross member 11 is inserted into the longitudinal member 12 to such an extent that it strikes its outer web 12a. The cross member 11 is also an extruded hollow profile with a rectangular cross-section, as can be seen in FIG. 11. Its height HQ is reduced compared to the height HL of the side member 12 by approximately twice the thickness DL of a belt 12c of the side member 12, so that its straps 11c rest against the straps 12c with play. It is therefore possible without difficulty to weld the belts 11c and 12c to one another in the overlapping area, as well as an inner web 11b of the cross member 11 with the inner web 12b of the side member 12; the joint of the two outer webs 11a and 12a can easily be designed so that a weld seam can be provided there. In this way, the corner knot E Execute extremely dimensionally stable, although a full face S is guaranteed. The hook-shaped holders 2 are fastened to this end face S; they are also welded on.
In den Fig. 2, 6 und 7 ist auch die detaillierte Ausbildung des plattenförmigen Belages 2 ohne weiteres ersichtlich. Er besteht demnach vor allem aus Holzplatten 21 als Trittele¬ menten, am besten in Form verleimter Sperrholzplatten. Die Holzplatten 21 sind entlang der Längsträger 12 von einem Halterahmen 22 eingefaßt, hier in Form eines einfachen U- Profileε, in das die Holzplatten 21 eingeschoben sind und die mittels in der Zeichnung weggelassener Verbindungsele¬ mente mit dem Tragrahmen 1 fest verbunden, beispielsweise vernietet sind, eine sekundäre Lagesicherung bildend, nun auch in Längsrichtung der Belagbühne.2, 6 and 7, the detailed design of the plate-shaped covering 2 is also readily apparent. It therefore mainly consists of wooden panels 21 as step elements, preferably in the form of glued plywood panels. The wooden panels 21 are bordered along the longitudinal beams 12 by a holding frame 22, here in the form of a simple U-profile, into which the wooden panels 21 are inserted and which are firmly connected to the supporting frame 1, for example riveted, by means of connecting elements omitted in the drawing , forming a secondary position lock, now also in the longitudinal direction of the platform.
In den Fig. 8 bis 10 und 11 ist die erfindungsgemäße Belag¬ bühne in einer Ausführung mit einer Klappe 23 in ihrer Funktionεfähigkeit noch erweitert; anεonsten entspricht sie der oben ausführlich erörterten Belagbühne, εo daß eε ge- nügt, die erforderlichen Veränderungen anzugeben. Die Klappe 23 (Fig. 12) iεt um eine Achεe AC schwenkbar, die von zwei Scharnierstücken 23a gebildet wird. Die Achse AC ist dem Längsträger 12 parallel gelegt. Im Bereich der Klappe 23 ist der Halterahmen 22 durch einen gegebenenfalls geringfügig anders profilierten Halterahmen 22' ersetzt, an dem die Scharnierstücke 23a - am besten beidseitig der Schenkel des Halterahmens 22' - befestigbar sind; anderer¬ seits ist es zweckmäßig, die Scharnierstücke 23a sowohl an dem oberen Gurt 12c des Längsträgerε 12 als auch an dessen innerem Steg 12b zu befestigen, beispielsweise mittels Nie¬ ten oder anderer geeigneter Verbindungselemente 23b. Die Klappe 23 ist so angeordnet, daß sie einerseits auf den oberen Gurt 11c eines Querträgers 11 und andererseits auf eine Auflageleiste 23c auflegbar ist, die zwischen den Längsträgern 12 eingespannt ist. Aufstellung der Bezugszeichen8 to 10 and 11, the covering platform according to the invention in an embodiment with a flap 23 is further expanded in its functionality; otherwise it corresponds to the covering platform discussed in detail above, so that it is sufficient to state the necessary changes. The flap 23 (FIG. 12) can be pivoted about an axis AC, which is formed by two hinge pieces 23a. The axis AC is placed parallel to the side member 12. In the area of the flap 23, the holding frame 22 is replaced by a holding frame 22 ', which may have a slightly different profile, to which the hinge pieces 23a - ideally on both sides of the legs of the holding frame 22' - can be attached; on the other hand, it is expedient to fasten the hinge pieces 23a both to the upper belt 12c of the longitudinal member 12 and to its inner web 12b, for example by means of rivets or other suitable connecting elements 23b. The flap 23 is arranged so that it can be placed on the one hand on the upper belt 11c of a cross member 11 and on the other hand on a support bar 23c, which is clamped between the side members 12.
