Abstract

PCT No. PCT/EP95/03251 Sec. 371 Date Jul. 28, 1997 Sec. 102(e) Date Jul. 28, 1997 PCT Filed Aug. 16, 1995 PCT Pub. No. WO96/15341 PCT Pub. Date May 23, 1996Working platforms for scaffolding must be light and functional and easily stackable. It must therefore be possible to include all their components with a long useful life in the static calculations as well. The requirements include both great rigidity in the corner joint of a rectangular bearing frame for the working platform and the smallest possible gaps between adjacent platforms. Above all, however, the smallest possible number of components must be used to keep the costs of such a working platform within limits. To this end the invention makes use of a U-shaped folded footplate (2) clamped between the longitudinal bearing members (11) of the bearing frame. If, in addition, at least the longitudinal bearing members (11) are rectangular hollow sections, no dirt or residual building material can enter the working platform.

Description

Die Erfindung betrifft eine Arbeitsbühne für ein Baugerüst oder dergleichen, die an zwei waagerechten Querholmen des Baugerüstes befestigbar ist, bestehend aus mindestens einem rechteckigen, aus Längs- und Querträgern zusammengesetzten Tragrahmen, dessen von den Querträgern gebildete Stirnseiten jeweils einer benachbarten Stirnseite weiterer an dem Baugerüst in der gleichen Höhe montierbarer Tragrahmen parallel sind, und aus einer an dem Tragrahmen gehaltenen, vorzugsweise als Lochblech ausgebildeten Lauffläche, wobei zwischen den Längsträgern ein begehbares, die Lauffläche aufweisendes Laufblech eingespannt ist, das unmittelbar an den Längsträgern befestigt ist, und das Laufblech U-förmig ausgebildet ist und dabei sein obenliegendes waagerechtes Stegblech als Lauffläche dient und beiderseits von dem Stegblech etwa rechtwinklig nach unten abgekantete senkrechte Gurtbleche aufweist. Eine derartige Arbeitsbühne ist aus der FR-A-1 424 365 bekannt.The invention relates to a work platform for scaffolding or the like, which on two horizontal crossbars of the Scaffolding is attachable, consisting of at least one rectangular, composed of longitudinal and cross members Support frame, the end faces formed by the cross members one adjacent end face each on the Scaffolding can be mounted in parallel at the same height are, and from a held on the support frame, preferably designed as a perforated tread, wherein a walkable surface between the side members, the tread having tread is clamped, which immediately the side members is attached, and the tread U-shaped is trained and his horizontal overhead Web plate serves as a tread and on both sides of it Web plate approximately perpendicular downwards bent Has belt plates. Such a work platform is known from FR-A-1 424 365.

Bei derartigen Arbeitsbühnen ist der jeweilige Tragrahmen mit einem plattenförmigen Belag ausgerüstet, der im allgemeinen aus einem verleimtem Sperrholz besteht und mit dem Tragrahmen vernietet ist. Die hohe Lochleibung während der Benutzung der Arbeitsbühne führt mit der Zeit zur Vergrößerung der Niet-Bohrungen im Sperrholz, so daß der Belag keinen Beitrag zur Steifigkeit der Arbeitsbühne zu leisten vermag und bei deren statischer Berechnung unberücksichtigt bleibt. Die wenn auch nur geringe zunehmende Verschiebbarkeit des Belages auf dem Tragrahmen trägt darüber hinaus zur Verminderung der Trittsicherheit während der Benutzung der Arbeitsbühne bei.In such work platforms, the respective support frame equipped with a plate-shaped covering, which in general consists of a glued plywood and with the Support frame is riveted. The high reveal during the Use of the work platform leads to enlargement over time the rivet holes in the plywood so that the covering does not To contribute to the rigidity of the work platform capable and not taken into account in their static calculation remains. The increasing displacement, if only slight of the covering on the support frame also carries to reduce surefootedness during use on the working platform.

Es ist deshalb auch bereits vorgeschlagen worden, daß die Sperrholzplatten von einem umlaufenden, auf den Gurten des Tragrahmens aufliegenden metallischen halterahmen gefaßt sind, besonders wenn dabei der Belag an seinem, Halterahmen mittels Verbindungselementen mit dem Tragrahmen vernietet ist. Der Halterahmen ist weniger als die Sperrholzplatten von bleibender Verformung in den Bohrungen für die Verbindungselemente bedroht, so daß verschleißbedingte Lockerungen im Bereich dieser Verbindungselemente auch bei hoher Belastung der Arbeitsbühne tatsächlich vermieden werden können. Eine derartige Arbeitsbühne ist allerdings aufwendig.It has therefore already been proposed that the Plywood panels from a circumferential, on the straps of the Support frame on metallic support frame are, especially if the covering on his, holding frame riveted to the supporting frame by means of connecting elements is. The holding frame is less than the plywood panels of permanent deformation in the holes for the connecting elements threatened, so that wear-related loosening in the area of these fasteners even at high Load on the working platform can actually be avoided can. However, such a work platform is complex.

Stattdessen ist es seit langem auch bekannt, die Lauffläche mittels einfacher Stahlböden aus Lochblechen auszubilden, die an ihren Längsseiten zu kurzen senkrechten, auf dem Tragrahmen aufliegend befestigten Stegstreifen abgekantet sind. Um ein ausreichendes Widerstandsmoment zu erzielen, sind diese berandenden Stegstreifen mindestens noch einmal und in der Regel mehrmals nach innen umgekantet, so daß die Lauffläche beiderseits von einem U-bis kastenförmigen, mehr oder weniger vollständigen, stets aber offenen Hohlprofil begrenzt ist. Die Anfertigung derartig abgekanteter Laufbleche auf Abkantbänken ist personal- und kostenintensiv, und die Laufbleche sind wegen der nicht geschlossenen und nicht schließbaren Hohlprofile nicht so verwindungssteif, wie das erwünscht ist. Im Betrieb läßt es sich zudem nicht vermeiden, daß Schmutz und Bauschutt durch das Lochblech in die Hohlprofile geraten und nur äußerst mühsam wieder entfernt werden können. Instead, it has long been known the tread to be made from perforated sheets using simple steel floors, that are too short on their long sides, on the Support frame with folded-on web strips are. To achieve a sufficient section modulus, are these bordering web strips at least once more and usually folded inwards several times so that the Tread on both sides from a U to box-shaped, more or less complete, but always open hollow profile is limited. The production of such bent treads on folding tables is labor-intensive and cost-intensive, and the treads are closed due to the and not closable hollow profiles not so rigid, as is desired. In addition, it cannot be operated avoid dirt and building rubble through the perforated plate in the hollow profiles get out and removed with great difficulty can be.

Es ist auch bekannt, daß zumindest die Längsträger aus einem vorzugsweise stranggepreßten, im Querschnitt etwa rechteckigen Hohlprofil bestehen, das aus je zwei jeweils parallelen senkrechten Stegen und waagerechten Gurten zusammengesetzt ist. Eine solche kastenförmige Ausbildung der Längsträger führt zu einer verwindungsfreien Ausbildung des Tragrahmens, insbesondere, wenn an dessen Eckknoten die Stege der Querträger jeweils bis zum äußeren Steg der Längsträger durchgeführt und an den Gurten und/oder Stegen der Längsträger angeschweißt sind. Ein solcher Eckknoten ist auf diese Weise sehr robust ausgebildet und hoch belastbar; außerdem hat eine derartige Konstruktion den Vorteil, daß die Stirnseiten des Tragrahmens wie schon dessen Längsseiten jeweils geschlossene Flächen bilden.It is also known that at least the side members are made of one preferably extruded, about in cross section rectangular hollow profile consist of two each parallel vertical webs and horizontal straps put together is. Such a box-shaped design of the Side member leads to a torsion-free training of Support frame, especially if the at the corner node Bridges of the cross member each to the outer web of the Side members carried and on the belts and / or webs the side members are welded on. Such a corner knot is very robust and highly resilient; in addition, such a construction has the advantage that the end faces of the support frame as before Long sides form closed areas.

Die Erfindung hat sich die Aufgabe gestellt, eine Arbeitsbühne der eingangs näher bezeichneten Art mit einfachen Mitteln betriebssicher zu gestalten und darüber hinaus so auszubilden, daß die Lauffläche die Steifigkeit der Arbeitsbühne auf Dauer verbessert und in die statische Berechnung einbezogen werden kann; darüber hinaus soll sie einfach herstellbar und mit dem Tragrahmen leicht verbindbar sein. Gleichzeitig soll dafür gesorgt werden, daß eine Ansammlung von Schmutz und Bauschutt in der arbeitsbühne sicher verhindert wird. Ferner soll die Anordnung so getroffen sein, daß mehrere Arbeitsbühnen gegenseitig ausreichend arretiert sind, wenn sie übereinander gestapelt gelagert werden.The invention has set itself the task of a work platform of the type specified at the beginning with simple Make funds operationally reliable and beyond so that the tread the rigidity of the Working platform improved in the long run and in the static calculation can be included; moreover it should easy to manufacture and easy to connect to the support frame be. At the same time, it should be ensured that a Accumulation of dirt and rubble in the work platform is safely prevented. The arrangement is also intended to be made in this way be that several working platforms are mutually sufficient are locked when stored stacked one above the other will.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß zumindest die Längsträger jeweils aus einem im Querschnitt etwa rechteckigen, geschlossenen Hohlprofil bestehen, das aus je zwei parallelen senkrechten Stegen und waagerechten Gurten zusammengesetzt ist, und daß die Gurtbleche an den inneren Stegen der Längsträger so befestigt sind, daß das Stegblech flächenparallel versetzt über den oberen Gurten der Längsträger angeordnet ist, daß die Querträger die gleiche tragrahmen-einheitliche Höhe wie die Längsträger aufweisen und daß an jeder Stirnseite des Tragrahmens mindestens zwei an den Querträgern befestigte, zum Überfangen der Querholme des Baugerüsts dienende, hakenförmige Halterungen vorgesehen sind.According to the invention the object is achieved in that at least the longitudinal beams each have a cross section rectangular, closed hollow profile consist of each two parallel vertical bars and horizontal straps is composed, and that the belt plates on the inner Webs of the side members are attached so that the web plate offset parallel to the surface over the upper belts of the Side member is arranged that the cross member is the same have the same frame height as the side members and that on each end face of the support frame at least two attached to the cross beams, to overlap the cross bars of the scaffolding serving hook-shaped brackets are.

Die Verknüpfung eines zumindest partiell aus geschlossenen Hohlprofilen gebildeten Tragrahmens mit einem beiderseits jeweils nur einfach um einen rechten Winkel abgekanteten Laufblech, das keinerlei weiteren Belag erfordert, führt zu einer außerordentlich verwindungssteifen Konstruktion, die dabei aber, mit geringem Aufwand, trotzdem sehr leichtgebaut ausgeführt werden kann.Linking an at least partially closed Hollow profiles formed support frame with one on both sides just beveled at a right angle Tread plate that does not require any other covering leads to an extremely rigid construction, the but, with little effort, still very lightweight can be executed.

Es ist vorteilhaft, wenn das Laufblech zumindest teilweise als Lochblech ausgebildet ist. Obwohl es sich am Bau nicht vermeiden läßt, daß Schmutz- und Baustoff-Partikel durch das Lochblech fallen, können sich diese in dem Laufblech nicht ansammeln, sondern fallen weiter. Die Arbeitsbühne bleibt entsprechend sauber.It is advantageous if the tread plate is at least partially is designed as a perforated plate. Although it is not in the construction can avoid that dirt and building material particles through the perforated plate fall, they can be in the tread plate do not accumulate, but continue to fall. The working platform stays clean.

Die Arbeitsbühne ist für eine gute Stapelbarkeit vorbereitet, wenn die Gurtbleche an den Längsträgern so befestigt sind, daß das Stegblech flächenparallel versetzt über den oberen Gurten der Längsträger angeordnet ist; besonders vorteilhaft ist es, wenn das Stegblech etwa um die halbe Breite der Gurtbleche die oberen Gurte des Tragrahmens überragt.The work platform is prepared for good stackability, if the belt plates are attached to the side members like this are that the web plate offset parallel to the surface the longitudinal beams are arranged above the upper belts; especially It is advantageous if the web plate about half the width of the belt plates the upper belts of the support frame towered over.

Die Arbeitsbühne ist außerordentlich verwindungssteif ausgebildet, wenn die Gurtbleche an den inneren Stegen der Längsträger angeschweißt sind, beispielsweise durch eine Folge von Widerstands-Punktschweißungen. Dabei können die an dem Tragrahmen stirnseitigen, mit den Längsträgern verschweißten Querträger als stehend-U-förmige Abkantprofile ausgebildet sein, wobei der senkrechte Profilsteg des jeweiligen Querträgers den Tragrahmen stirnseitig berandet und die Profilgurte so ausgeklinkt sein können, daß der Profilsteg gleichzeitig das Hohlprofil des jeweiligen Längsträgers verschließend abdeckt. Auf diese Weise steht die gesamte Fläche der Stirnseite des Tragrahmens - beispielsweise zur Befestigung von Verbindungselementen - zur Verfügung, und das Hohlprofil der Längsträger ist auch stirnseitig verschließbar.The work platform is extremely torsion-resistant, if the belt plates on the inner webs of the Side members are welded, for example by a Sequence of resistance spot welds. The on the end of the support frame, welded to the side members Crossbeams as upright U-shaped folding profiles be formed, the vertical profile web of the respective Cross-member edged the end of the support frame and the profile straps can be released so that the Profile web simultaneously the hollow profile of the respective Covering the longitudinal member. That way it stands the entire area of the end face of the support frame - for example for fastening fasteners - for Available, and the hollow profile of the side members is also lockable on the front.

Es ist zweckmäßig, wenn die oberen Profilgurte das Laufblech unterfangen, so daß dieses auch an den Stirnseiten des Tragrahmens so gelagert ist, daß Durchbiegung vermieden wird.It is useful if the upper profile straps the tread undertaking, so that this also on the end faces the support frame is mounted so that deflection is avoided becomes.

Wenn erfindungsgemäß ferner die unteren Profilgurte oberhalb der unteren Gurte der Längsträger enden, sind, beim Stapeln mehrerer Arbeitsbühnen, die Laufbleche und damit die gesamte Arbeitsbühne in der jeweils nächsthöheren Arbeitsbühne sicher orientiert, jedenfalls zumindest in der für eine sichere Stapelung wichtigen Richtung quer zu der Längserstreckung der Arbeitsbühnen. Ganz zwanglos ergibt sich eine solche Anordnung, wenn die Querträger die gleiche tragrahmen-einheitliche Höhe wie die Längsträger aufweisen: oben ist der Überstand über den Längsträgern dann genauso groß wie unten die Einrückung über die Längsträger-Unterkante.If, according to the invention, the lower profile belts are also above the lower straps of the side members end, when Stacking several work platforms, the running plates and so the entire work platform in the next higher work platform certainly oriented, at least in the for safe stacking important direction across the Longitudinal extension of the work platforms. Quite casually such an arrangement if the cross member is the same Uniform frame height as the side members have: the protrusion above the side members is the same at the top as large as below the indentation over the lower edge of the side member.

Die Arbeitsbühne läßt sich auf einfache Weise an dem Baugerüst befestigen, wenn an jeder Stirnseite des Tragrahmens mindestens zwei an den Querträgern befestigte, die Querholme des Baugerüsts überfangende, hakenförmige Halterungen vorgesehen sind. Dabei können benachbarte Arbeitsbühnen mit ihren Stirnseiten eng aneinanderliegend auf dem gleichen Querholm gelagert werden, wenn die Halterungen an den Querträgern des Tragrahmens in der zu den Stirnseiten parallelen Richtung so angeordnet und von den von den Längsträgern gebildeten Längsseiten des Tragrahmens so beabstandet sind, daß sie gegen die Halterungen an dem benachbarten Querträger eines weiteren gleichen Tragrahmens versetzt sind in der Weise, daß bei fluchtenden Tragrahmen die Halterungen an dem gleichen Querholm angeordnet sein können. Es ist dabei zweckmäßig, wenn die Halterungen an den Querträgern paarweise und in der Nähe der Längsträger vorgesehen sind, so daß die Belastung der Arbeitsbühne möglichst gleichmäßig verteilt in das Baugerüst eingeleitet wird. In einfacher und effektiver Weise können die Halterungen an den Querträgern des Tragrahmens angeschweißt sein.The work platform can be easily attached to the scaffolding attach if on each face of the support frame at least two cross bars attached to the cross members of the scaffolding, hook-shaped brackets are provided. Adjacent work platforms can be used their faces close together on the same Crossbars are stored when the brackets on the crossbars of the support frame in the parallel to the end faces Direction so arranged and from that of the side members formed longitudinal sides of the support frame so spaced are against the brackets on the adjacent one Cross member of another same support frame offset are in such a way that the brackets with aligned support frame can be arranged on the same cross member. It is useful if the brackets on the cross members provided in pairs and near the side members are so that the load on the working platform is as possible is evenly distributed into the scaffolding. In the brackets can be attached in a simple and effective manner be welded to the cross members of the support frame.

Handelt es sich bei der erfindungsgemäß ausgebildeten Arbeitsbühne um ein sich besonders lang erstreckendes Bauteil, dann kann es von Vorteil für die Steifigkeit der Arbeitsbühne sein, wenn an dem Tragrahmen parallel zu den Querträgern mindestens eine Versteifungsstrebe zwischen den Längsträgern eingespannt ist, zweckmäßigerweise etwa in der Mitte zwischen den beiderseitigen Querträgern.Is the working platform designed according to the invention a particularly long component, then it can be beneficial for the rigidity of the work platform be if parallel to the on the support frame Cross members at least one stiffening strut between the Sides is clamped, expediently in the Middle between the crossbeams on both sides.

Die Erfindung reduziert die für eine Arbeitsbühne erforderlichen Bauteile auf wenige, einfach gestaltete und deshalb auch billig herstellbare Bauelemente, die aber insgesamt bei durchgängiger Leichtbauweise die Bereitstellung einer sehr formstabilen und hochbelastbaren Arbeitsbühne erlauben.The invention reduces those required for a working platform Components on a few, simply designed and therefore also inexpensive to manufacture components, but overall the provision with consistent lightweight construction a very stable and heavy-duty work platform allow.

Eine Arbeitsbühne nach der Erfindung besteht entsprechend Fig. 1 bis 3 im wesentlichen aus einem Tragrahmen 1, einem Laufblech 2 und hakenförmigen Halterungen 3.A work platform according to the invention exists accordingly 1 to 3 essentially from a support frame 1, a Running plate 2 and hook-shaped brackets 3.

Der Tragrahmen 1 ist aus zwei Längsträgern 11 und zwei Querträgern 12 zusammengesetzt, die miteinander in den Ecken 13 des Tragrahmens 1 verschweißt sind. Etwa in der Mitte zwischen den Querträgern 12 ist eine Versteifungsstrebe 14 zwischen den Längsträger 11 eingespannt und mit diesen ebenfalls durch Schweißnähte stoffschlüssig verbunden. Die Querträger 12 bilden an den Tragrahmen 1 stirnseitig geschlossene Flächen aus, an denen die Halterungen 3 so angeschweißt sind, daß der an diesen vorgesehene Haken 31 in der Gebrauchslage nach unten weist, so daß die Hakenösen 32 jeweils einer Stirnseite la des Tragrahmens 1 einen Querholm des Baugerüstes überfangen können.The support frame 1 is composed of two longitudinal beams 11 and two Cross members 12 assembled together in the Corners 13 of the support frame 1 are welded. About in the In the middle between the cross members 12 is a stiffening strut 14 clamped between the side members 11 and with these also cohesively connected by welds. The cross beams 12 form on the end of the support frame 1 closed surfaces on which the brackets 3 are welded so that the hook provided on them 31 points downwards in the position of use, so that the hook eyelets 32 each have an end face la of the support frame 1 can cross a crossbar of the scaffolding.

Das Laufblech 2 ist entsprechend Fig. 1 als Lochblech ausgebildet und genauso zwischen den Längsträgern 11 eingespannt wie die Versteifungsstrebe 14. In der Fig. 3 sind Widerstands-Punktschweißungen 4 zwischen dem Tragrahmen 1 und dem Laufblech 2 angedeutet, mit denen dessen in Gebrauchslage senkrechte Gurtbleche 21 stoffschlüssig mit den Längsträgern 11 verbunden sind. Diese Längsträger 11 sind als jeweils aufrecht stehend rechteckiges, stranggepreßtes Hohlprofil 110 ausgeführt, das entsprechend Fig. 6 aus je einem waagerechten oberen und unteren Gurt lla,llb und je einem diese verbindenden inneren und äußeren Steg llc,lld zusammengesetzt ist.1 is designed as a perforated plate and also clamped between the side members 11 as the stiffening strut 14. In Fig. 3 are Resistance spot welds 4 between the supporting frame 1 and indicated the tread 2, with which its in the use position vertical belt plates 21 integrally with the Side members 11 are connected. These longitudinal beams 11 are as an upright rectangular extrusion Hollow profile 110 executed, according to FIG. 6 from each a horizontal upper and lower belt lla, llb and each an inner and outer web 11c, lld connecting these is composed.

In der Fig. 4 ist das Profil eines der Querträgers 12 und dessen relative Lage an den Längsträgern 11 gut zu erkennen; er ist U-förmig aus einem Profilsteg 12a und je einem oberen und unteren, von dem Profilsteg 12a abgekanteten Profilgurt 12b,12c zusammengesetzt. Der Querträger 12 ist zwischen den Längsträgern 11 so eingespannt, daß sein oberer Profilgurt 12b über deren oberen Gurte 11a um eine Höhe h1 übersteht (Fig. 6). Die so gebildeten überstehenden Zwickel 12d in der Breite der Längsträger 11 sind (Fig. 6, 7) an den Querträgern 12 ausgeklinkt.4, the profile of one of the cross members 12 and its relative position on the longitudinal members 11 can be clearly seen; it is composed of a U-shaped profile web 12a and an upper and a lower profile belt 12b, 12c, which is bent over by the profile web 12a. The cross member 12 is clamped between the side members 11 so that its upper profile belt 12b protrudes over their upper belts 11a by a height h 1 (FIG. 6). The protruding gussets 12d formed in this way in the width of the longitudinal members 11 are notched on the cross members 12 (FIGS. 6, 7).

Andererseits sind die unteren Profilgurte 12c entsprechend Fig. 4 um eine Höhe h2 über die unteren Gurte 11b der Längsträger 11 in den Tragrahmen 1 eingerückt. Die Höhe h1 ist höchstens so groß wie die Höhe h2, so daß (Fig. 8) übereinander gelegte Arbeitsbühnen leicht und sicher gestapelt werden können. Sind die Höhen h1 und h2 gleich, dann haben auch die Querträger 12 die tragrahmen-einheitliche Höhe H wie die Längsträger 11.On the other hand, the lower profile belts 12c according to FIG. 4 are indented into the supporting frame 1 by a height h 2 over the lower belts 11b of the side members 11. The height h 1 is at most as high as the height h 2 , so that (FIG. 8) stacked work platforms can be stacked easily and safely. If the heights h 1 and h 2 are the same, then the cross members 12 also have the height H which is the same as that of the side members 11.

Die Halterungen 3 sind, bezüglich der Querträger 12, nicht spiegelbildlich an dem Tragrahmen 1 vorgesehen, sondern vielmehr an dessen beiden Stirnseiten 1a paarweise versetzt, so daß benachbarte Tragrahmen 1 auf den gleichen Querholm eines Baugerüstes aufgelegt werden können, ihre Längsseiten 1b aber trotzdem bündig sind. In der Fig. 7 ist die Situation leicht zu erkennen, weil die nicht sichtbaren Halterungen 3 an der in Bezug auf die Zeichnungsebene hinten liegende Stirnseite 1a ebenfalls angedeutet sind. Die Halterungen 3 sind durchweg an den Profilstegen 12a angeschweißt und (Fig. 5) einstückig entsprechend mit einem Konsolblech 33 versehen.The brackets 3 are, with respect to the cross member 12, not provided in mirror image on the support frame 1, but rather, offset in pairs on its two end faces, so that adjacent support frame 1 on the same Querholm a scaffolding can be placed on their Long sides 1b are still flush. 7 is easy to see the situation because the invisible ones Brackets 3 on the rear in relation to the drawing plane lying end face 1a are also indicated. The Brackets 3 are welded to the profile webs 12a throughout and (Fig. 5) in one piece with a corresponding Provide bracket plate 33.

Das Laufblech 2 ist ebenfalls (Fig. 6) U-förmig ausgebildet. Zwischen den Gurtblechen 21 ist dabei ein Stegblech 22 vorgesehen, dessen in Gebrauchslage waagerechte obere Seite 22a die Lauffläche 20 bildet (Fig. 1). Seine untere Seite 22b liegt auf den oberen Profilgurten 12b der Querträger 12 auf, während der in den Tragrahmen 1 hineinreichende Teil der Gurtbleche 21 an den inneren Stegen 11c der Längsträger 11 mit diesen flächig anliegend verbunden ist, am einfachsten wie oben bereits erwähnt mittels Widerstand-Punktschweißungen 4.The running plate 2 is also (Fig. 6) U-shaped. There is a web plate between the belt plates 21 22 provided, the horizontal upper in the use position Page 22a forms the tread 20 (Fig. 1). His lower Page 22b lies on the upper profile belts 12b of the crossbeam 12, while reaching into the support frame 1 Part of the belt plates 21 on the inner webs 11c The longitudinal beam 11 is connected to the latter in a flat manner, easiest as already mentioned above using resistance spot welding 4th

Eine allenfalls vorgesehene Versteifungsstrebe 14 ist stattdessen am besten mittels einer Kehlnaht an den Längsträgern 11 angeschweißt. An optional stiffening strut 14 is instead, it is best to use a fillet weld on the side members 11 welded.
