Abstract

For a scaffolding, in particular for a building scaffolding, having upright members, horizontal bars, cross-members and boards, it is proposed to insert and to fasten U-shaped profiles in the ends of the boards and to form integrally, on the outer side of the U-shaped profiles, connecting profiles so that the latter can engage on cross- members. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Gerüst, insbesondere Baugerüst, mit Ständern, Horizontalriegeln Traversen und einstückigen kastenförmigen Metall-Bohlen, wobei an den En­den der Bohlen U-Profile befestigt sind und wobei auf der Außenseite der U-Profile symmetrisch in bezug auf die hori­zontale Mittelebene Anschlußprofile einstückig angeformt sind, welche an den Traversen angreifen.The invention relates to a scaffolding, in particular scaffolding, with stands, horizontal crossbars and one-piece box-shaped metal planks, U-profiles are attached to the ends of the planks and being symmetrical on the outside of the U-profiles with respect to the horizontal central plane Connection profiles are integrally formed, which attack the crossbars.

Es wurde bereits ein Gerüst dieser vorgenannten Art vorge­schlagen. Die hierbei verwendeten U-Profile bestehen aus profilierten Stahlblechen, die also aus Blechtafeln durch entsprechendes Umbiegen hergestellt werden. Mit diesen pro­filierten Stahlblechen sind die Enden der Bohlen beschla­gen. Da die Bohlen aus Holz sind, sind die Schenkel der profilierten Stahlbleche auf die Bohlen außen aufgenagelt. Von diesen Schenkeln ausgehend ist dann das Stahlblech nach innen umgekantet und weiterhin so gekantet, daß ein Hohl­kopf bzw. eine im Querschnitt gesehen etwa trapezförmige hohle Leiste entsteht. Der Steg des U-Profiles, welches das jeweilige Bohlenende umfaßt, besteht also aus zwei Teilen, die in der Mitte noch einen gewissen Abstand voneinander haben. Diese Stahlblechkontruktion hatte für die Praxis mehrere Nachteile. Einmal kann sich die Vernagelung der Blechschenkel im Laufe der Zeit leicht lösen, so daß sich dann die Schenkel ganz oder teilweise aufstellen und Stol­perkanten auf den Gerüstbohlen bilden können. Des weiteren ist das Profilieren bzw. Umkanten der Stahlbleche recht aufwendig und es können dabei nur verhältnismäßig dünne Bleche Verwendung finden. Dadurch ergeben sich in dem rau­hen Einsatzgebiet des Gerüstbaues, in dem die Bohlen oft­mals geworfen werden oder beim Abbau eines Gerüstes fallen­gelassen werden, erhebliche Beschädigungen. Wenn die Stahl­blechprofilierungen auch nur stellenweise beschädigt oder eingedrückt werden, ist die gesamte Bohle nicht mehr zu ge­brauchen oder muß entsprechend aufwendig repariert werden.A scaffold of this type has already been proposed. The U-profiles used here consist of profiled steel sheets, which are made from sheet metal by bending them accordingly. The ends of the planks are covered with these profiled steel sheets. Since the planks are made of wood, the legs of the profiled steel sheets are nailed to the outside of the planks. Starting from these legs, the steel sheet is then folded inwards and further folded so that a hollow head or, as seen in cross section, an approximately trapezoidal hollow strip is produced. The web of the U-profile, which encompasses the respective screed end, consists of two parts that are still a certain distance apart in the middle. This steel sheet design had several disadvantages in practice. On the one hand, the nailing of the sheet metal legs can easily loosen in the course of time, so that the legs can then stand up in whole or in part and tripping edges can form on the scaffolding planks. Furthermore, the profiling or edging of the steel sheets is quite complex and it can only be relatively thin Find sheet metal. This results in considerable damage in the rough application area of scaffolding, in which the planks are often thrown or dropped when a scaffold is dismantled. If the steel sheet profiles are even damaged or dented in places, the entire screed can no longer be used or must be repaired accordingly.

Des weiteren ist aus der DE-A-35 39 507 eine Gerüstrahmen­tafel bekannt, die Längsholme und an den Stirnseiten Quer­leisten aufweist, auf welchen eine Platte befestigt ist, die die Gang- und Arbeitsfläche bildet und als Holzbelag bezeichnet, ist, die aber auch aus verschiedenen geeigneten Werkstoffen bestehen kann. An die Querleiste sind drei Ha­ken mit Abstand voneinander eingeschweißt. Die Querleiste hat nach innen umgebogene Schenkel, die in die Längsholme eingreifen. Außerdem sind noch Nietlaschen vorgesehen, so daß eine Befestigung mittels Blindnieten erfolgt. Die Haken sind aus einem Blech geformt, sie sind also innen hohl. Ab­gesehen von dem komplizierten Aufbau dieser Gerüstrahmenta­fel und einem entsprechenden Fertigungsaufwand ist die Kon­struktion wenig robust, d.h. wenn eine solche Tafel vom Ge­rüst fallengelassen wird und sie auf die Haken trifft, wer­den diese sich verformen bzw. beschädigt werden und es kön­nen auch leicht die Nietbefestigungen ausbrechen. Diese Ta­fel hat auch den weiteren Nachteil, daß sie nur einseitig benutzt werden kann.Furthermore, from DE-A-35 39 507 a scaffold panel is known which has longitudinal spars and transverse strips on the end faces, on which a plate is fastened, which forms the aisle and work surface and is referred to as wood covering, but which is also made of different suitable materials can exist. Three hooks are welded to the cross bar at a distance from each other. The cross bar has inwardly bent legs that engage in the longitudinal bars. In addition, rivet tabs are also provided so that they are fastened by means of blind rivets. The hooks are made of sheet metal, so they are hollow on the inside. Apart from the complicated structure of this scaffold panel and a corresponding manufacturing effort, the construction is not very robust, i.e. if such a panel is dropped from the scaffolding and hits the hooks, they will deform or be damaged and the rivet fastenings can easily break out. This board also has the further disadvantage that it can only be used on one side.

Ferner ist aus der DE-A-3020389 eine Abhubsicherung für Baugerüste bekannt, wobei die Laufplanken mittels Haken an Quertraversen angehängt werden, die von einer Schiene über­deckt werden. Die Haken sind mittels Hohlnieten an den Planken befestigt und befinden sich nur an den Enden der Breitseite jeder Planke.Furthermore, from DE-A-3020389 a lift-off protection for scaffolding is known, the running boards being attached to crossbars by means of hooks which are covered by a rail. The hooks are attached to the planks by means of hollow rivets and are only located at the ends of the broad side of each plank.

Ein weiterer Stand der Technik ergibt sich aus der DE-A-­3444666. Diese beschreibt eine aus Holz bestehende Holzka­stentafel, wobei in die obere und untere Platte als Ver­stärkungseinlage je ein Metallblech eingebaut ist. Diese Hohlkastentafel weist an den Stirnenden aus Metal beste­hende Beschläge mit jeweils an den Ecken angeordneten Auf­lagen auf. Diese Metallbeschläge sind zwar U-förmig ausge­bildet, aber die beiden Schenkel liegen wieder außen auf der Hohlkastentafel auf und sind durch Nieten befestigt. Abgesehen davon, daß hierdurch wieder Stolperkanten gebil­det werden, ist auch die Nietbefestigung unsicher. Der kom­pliziert geformte Beschlag mit den beiden Eckauflagern kann auf keinen Fall durch Strangziehen hergestellt werden.Another prior art results from DE-A-3444666. This describes a wooden box panel made of wood, whereby a metal sheet is installed in the upper and lower plate as reinforcement insert. This box girder panel has metal fittings at the ends, each with supports arranged at the corners. These metal fittings are U-shaped, but the two legs rest on the outside of the box girder panel and are fastened by rivets. Apart from the fact that tripping edges are formed again, the rivet attachment is also unsafe. The complicated shaped fitting with the two corner supports can never be produced by pulling.

Schließlich ist aus der FR-B-2092295 ein Gerüst mit Bohlen bekannt, die an ihren Ecken mit vertikalen Löchern versehen sind, in die Gerüstzapfen eingreifen sollen. Dies ist bei der bekannten Konstruktion mit erheblichen Schwierigkeiten verbunden. Beim Aufbau eines Baugerüstes werden nämlich zunächst die Ständer mit den Querriegeln aufgestellt, die dann aber anfangs noch nicht ganz feststehen. Es ist dann mühsam, eine solche bekannte Bohle mit den Löchern genau auf die Zapfen aufzusetzen, die sich an den Querriegeln be­finden. Man muß sich vergegenwärtigen, daß der betreffende Bauarbeiter die einzusetzende Bohle etwa auf 2 bis 2,5 m Höhe halten muß, um mit den Löchern die betreffenden Zapfen zu treffen. Er kann aber dann weder die Löcher noch die Zapfen sehen und muß somit lange suchen, bis er die rich­tige Lage der Bohle gefunden hat.Finally, from FR-B-2092295 a scaffold with planks is known, which are provided at their corners with vertical holes in which scaffold pegs are to engage. This is associated with considerable difficulties in the known construction. When building scaffolding, the stands with the crossbars are initially set up, but are not yet completely fixed at the beginning. It is then tedious to place such a known screed with the holes exactly on the pins that are located on the crossbars. It must be remembered that the construction worker in question must hold the screed to be used at a height of approximately 2 to 2.5 m in order to hit the relevant pegs with the holes. But then he can neither see the holes nor the cones and must therefore search for a long time until he has found the correct position of the screed.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Gerüst zu schaffen, welche eine sichere und dauerhafte Be­festigung der wichtigsten Gerüstteile untereinander gestat­tet, welches ferner eine einfache Handhabung der einzelnen zusammenzusetzenden Teile ermöglicht und welches schließ­ lich eine so stabile Konstruktion mit sich bringt, daß es auch den höchsten Beanspruchungen standhält.In contrast, the invention is based on the object of creating a scaffold which permits secure and permanent fastening of the most important scaffold parts to one another, which furthermore enables simple handling of the individual parts to be assembled and which closes Lich has such a stable construction that it can withstand the highest demands.

Die gestellte Aufgabe wird erfindungsgemäß daduch gelöst, daß jedes U-Profil mit dem jeweiligen Anschlußprofil aus einem stranggezogenen Teil besteht und sich über die Breite der Bohle erstreckt, daß die beiden Schenkel des U-Profiles in das Innere einer einstückigen als kastenförmiges Metall­profil ausgebildeten Bohle eingreifen, und daß jedes U-Pro­fil an dem betreffenden Ende der Bohle derart angeschweißt ist, daß die Schweißnähe zwischen den Stirnenden der oberen und unteren Wand der Bohle einerseits und dem Steg des U-­Profiles andererseits verlaufen.The object is achieved according to the invention in that each U-profile with the respective connection profile consists of an extruded part and extends over the width of the screed, that the two legs of the U-profile engage in the interior of a one-piece screed designed as a box-shaped metal profile , and that each U-profile is welded to the relevant end of the screed in such a way that the weld proximity between the front ends of the upper and lower wall of the screed on the one hand and the web of the U-profile on the other hand.

Figur 1 zeigt ein Ausführungsbeispiel der Erfindung anhand eines Ausschnittes aus einem Gerüst, insbesondere einem Baugerüst, wobei ein Teil des Ständers 1, zum Beispiel ei­nes Ständerrohres in Ansicht und eine hiermit in Verbindung stehende U-förmige, nach oben hin öffnende Traverse 2 im Vertikalschnitt gezeichnet ist. Ferner sind die beidersei­tig anzuschließenden Bohlen 3 und 4 mit ihren Endteilen im Vertikalschnitt dargestellt, wobei diese Bohlen einstückig und als kastenförmiges Metallprofil (Leichtmetall) mit ei­ner oberen Wand und einer unteren Wand, die ebenfalls ge­schnitten gezeichnet sind, ausgeführt sind. Ferner können an geeigneten Stellen Horizontalriegel 5 in an sich bekann­ter Weise angeschlossen sein. Die Anordnung dieser Horizon­talriegel ist in bekannter Weise den Gegebenheiten ange­paßt.Figure 1 shows an embodiment of the invention using a section of a scaffold, in particular a scaffolding, with a part of the stand 1, for example a stand tube in view and a related U-shaped, upward opening cross member 2 drawn in vertical section is. Furthermore, the planks 3 and 4 to be connected on both sides are shown with their end parts in vertical section, these planks being made in one piece and as a box-shaped metal profile (light metal) with an upper wall and a lower wall, which are also shown in section. Furthermore, horizontal bars 5 can be connected at suitable points in a manner known per se. The arrangement of these horizontal bars is adapted to the circumstances in a known manner.

Wie Figur 1 ferner verdeutlicht, sind in den Enden der stirnseitig offenen Bohlen 3 und 4 U-Profile 6 eingesetzt und befestigt. Auf der Außenseite dieser U-Profile 6 ist jeweils ein Anschlußprofil 33 einstückig angeformt, welches wie dargestellt an der Traverse, und zwar an den nach oben ragenden Schenkeln der nach oben geöffneten U-förmigen Tra­verse 2 angreift. Bei diesem Ausführungsbeispiel besteht das U-Profil 6 einerseits aus einem vertikal verlaufenden Steg 7 und zwei horizontal verlaufenden Schenkeln 8, 9 und das Anschlußprofil 33 andererseits aus einem Abstandsstück 10 und einer doppelseitigen Leiste 11. Vorteilhafterweise ist sowohl das U-Profil 6 als auch das Anschlußprofil 33 symmetrisch in bezug auf die horizontale, senkrecht zur Bildebene verlaufende Mittelebene ausgebildet. Diese Aus­bildung hat den Vorteil, daß das Profil durch Strangziehen hergestellt und von dem Strang in gewünschter Länge abge­trennt werden kann und daß das Profil immer richtig, auch nach Umwenden um 180 Grad, an dem Ende der betreffenden Bohle befestigbar ist. Die Schenkel 8 und 9 des U-Profiles 6 greifen in das Innere der Bohle ein, womit bereits ein fester Halt gewährleistet ist. Eine weitere wesentliche Si­cherung und eine einfache Herstellung ergibt sich dadurch, daß die U-Profile 6 an den Enden der Bohlen 3, 4 ange­schweißt sind, wobei die Schweißnähte 12 und 13 zweckmäßi­gerweise zwischen den Stirnenden der Bohlenwandungen einer­seits und dem Steg 7 andererseits vorgesehen sind.As FIG. 1 further clarifies, U-profiles 6 are inserted and fastened in the ends of the planks 3 and 4 which are open at the end. On the outside of these U-profiles 6, a connection profile 33 is formed in one piece, which, as shown, engages the crossmember, namely on the upwardly projecting legs of the upwardly open U-shaped crossmember 2. In this embodiment, the U-profile 6 consists on the one hand of a vertically extending web 7 and two horizontally extending legs 8, 9 and the connecting profile 33, on the other hand, consists of a spacer 10 and a double-sided strip 11. Advantageously, both the U-profile 6 and the connecting profile 33 are formed symmetrically with respect to the horizontal central plane running perpendicular to the image plane. This design has the advantage that the profile can be produced by pulling and separated from the strand in the desired length and that the profile can always be fastened correctly, even after turning 180 degrees, at the end of the screed in question. The legs 8 and 9 of the U-profile 6 engage in the interior of the screed, which already ensures a firm hold. Another essential safeguard and simple manufacture results from the fact that the U-profiles 6 are welded to the ends of the planks 3, 4, the weld seams 12 and 13 advantageously being provided between the front ends of the plank walls on the one hand and the web 7 on the other hand.

Die U-Profile 6 mit ihren Anschlußprofilen 33 bestehen vor­teilhafterweise aus einem einzigen stranggezogenen Teil, welches in der Praxis vom Strang auf eine Länge abgeschnit­ten wird, die etwa der Breite der Bohle entspricht. Dies gilt für alle entsprechenden Profile gemäß der Erfindung, auch nach den Figuren 3 und 4.The U-profiles 6 with their connecting profiles 33 advantageously consist of a single extruded part, which in practice is cut from the strand to a length which corresponds approximately to the width of the screed. This applies to all corresponding profiles according to the invention, also according to FIGS. 3 and 4.

Figur 2 veranschaulicht, daß die erfindungsgemäße Ausge­staltung der Profile germäß Figur 1 auch bei anders gestal­teten Traversen 14 und 15 und bei anderer Ausgestaltung der Horizontalriegel, nämlich bei Rechteckrohren 16 oder Oval­rohren 17 anwendbar sind. Für die gleichen oder gleichwir­kenden Teile sind in Figur 2 die gleichen Bezugszeichen wie in Figur 1 verwendet worden.FIG. 2 illustrates that the design of the profiles according to the invention according to FIG. 1 can also be used with differently designed cross members 14 and 15 and with a different design of the horizontal bars, namely with rectangular tubes 16 or oval tubes 17. The same reference numerals as in FIG. 1 have been used in FIG. 2 for the same or equivalent parts.

Figur 3 zeigt im Vertikalschnitt eine andere Ausgestaltung eines Profiles, wobei der linke Teil, der mit dem Ende der betreffenden Bohle befestigt ist, wieder als U-Profil 6 mit Steg 7 und zwei Schenkeln 8, 9 ausgebildet ist, während das rechte Teil, nämlich das Anschlußprofil als Kastenprofil 19 ausgebildet ist. Dieses Kastenprofil besitzt an der Ober­seite und Unterseite bzw. an den beiden waagerechten Wänden Durchbrechungen 20 und 21, in welche die in Figur 4 darge­stellten Stützen 29 und 30 eingreifen können, die ihrer­seits im Querschnitt dreieckige Kopfteile 31 und 32 besit­zen, wodurch das Aufschieben der betreffenden Kastenprofile 19 erleichtert wird. Diese Stützen 29 und 30 sind zweck­mäßigerweise an einer Traverse 18 angebracht, die im Aus­führungsbeispiel nach Figur 4 als rechteckiges oder quadra­tisches Hohlprofil ausgebildet ist.Figure 3 shows in vertical section another embodiment of a profile, the left part, which is attached to the end of the screed concerned, again with a U-profile 6 Web 7 and two legs 8, 9 is formed, while the right part, namely the connection profile is designed as a box profile 19. This box profile has openings 20 and 21 on the top and bottom or on the two horizontal walls, in which the supports 29 and 30 shown in FIG. 4 can engage, which in turn have triangular head parts 31 and 32 in cross section, as a result of which the relevant ones are pushed open Box profiles 19 is facilitated. These supports 29 and 30 are expediently attached to a crossmember 18, which in the exemplary embodiment according to FIG. 4 is designed as a rectangular or square hollow profile.

Wie insbesondere Figur 3 verdeutlicht, ist das Anschlußpro­fil 19 zu beiden Seiten der Durchbrechungen 20 und 21 mit äußeren Wulsten 22, 23, 24 und 25 verstärkt. Diese Wulste können im Bereich ihrer Enden mit Bohrungen 34 zum Einset­zen von Haltestiften oder mit Gewindebohrungen zum Ein­schrauben von Halteschrauben versehen sein.As particularly shown in Figure 3, the connection profile 19 is reinforced on both sides of the openings 20 and 21 with outer beads 22, 23, 24 and 25. These beads can be provided in the region of their ends with holes 34 for inserting retaining pins or with threaded holes for screwing in retaining screws.

Figur 4 zeigt noch eine weitere vorteilhafte Ausgestaltung der Erfindung, wonach die Anschlußprofile 19 (Figur 4) bzw. 33 (Figur 1 und 2) mindestens teilweise von einem Profil 26 für eine Belagsicherung überdeckt sind. Dieses Profil 26 kann also sowohl bei der Ausführung nach Figur 4 als auch bei den Ausführungen nach den Figuren 1 und 2 eingesetzt werden. Neben der Belagsicherung hat dieses Profil noch den weiteren wesentlichen Vorteil, daß die Anschlußstellen bzw. die Rohrstöße überdeckt sind, so daß sich bei dem Übergang von einem Bohlenende zum anderen Bohlenende keine Stolper­kanten ergeben und auch das Überfahren beispielsweise mit einer Schubkarre erleichtert wird. Vorteilhafterweise be­sitzt das Profil 26 eine nach oben gewölbte Leiste und auf deren Unterseite einen Steg 28, der als Stütze dient und die Last auf beliebige darunter befindliche Gerüstteile überträgt.FIG. 4 shows yet another advantageous embodiment of the invention, according to which the connecting profiles 19 (FIG. 4) or 33 (FIGS. 1 and 2) are at least partially covered by a profile 26 for securing the covering. This profile 26 can therefore be used both in the embodiment according to FIG. 4 and in the embodiments according to FIGS. 1 and 2. In addition to securing the covering, this profile has the further significant advantage that the connection points or the pipe joints are covered, so that there are no tripping edges during the transition from one end of the plank to the other, and that driving over, for example with a wheelbarrow, is made easier. Advantageously, the profile 26 has an upwardly curved ledge and on the underside thereof a web 28 which serves as a support and transfers the load to any scaffolding parts located underneath.

Figur 5 zeigt einen Gerüstrahmen, welcher vertikal aufge­stellt ist und welcher quer zu dem zusammensetzbaren Ge­samtgerüst verläuft. Der Gerüstrahmen besteht im wesentli­chen aus zwei Ständern 101 und 102, die aus zylindrischen Leichtmetallrohren gebildet sind. Auch alle übrigen nach­folgend erläuterten Teile bestehen zweckmäßigerweise aus Leichtmetall, insbesondere einer Aluminiumlegierung. An ih­ren oberen Enden sind die beiden Ständer 101, 102 durch eine Traverse 103 und an ihren unteren Enden durch eine nach oben hin gewölbte Schiene 104 miteinander fest zu dem Rahmen verbunden. Ferner sind die Ständer 101, 102 an ihren oberen Enden mit Zapfen 108, 109 versehen, die stirnseitig konische Abschrägungen 110, 111 besitzen und die in die Ständer eines benachbarten nicht gezeichneten darüber be­findlichen Rahmens einsteckbar sind. Die Außendurchmesser der Zapfen 108, 109 und die Innendurchmesser der Ständer 101, 102 sind entsprechend aufeinander abgepaßt. Zwischen der Traverse 103 und den Ständern 101, 102 sind zur Ver­stärkung schräg verlaufende Stützen 105 und 106 ange­schweißt.FIG. 5 shows a scaffold frame which is set up vertically and which runs transversely to the overall scaffold which can be assembled. The scaffold frame essentially consists of two stands 101 and 102, which are formed from cylindrical light metal tubes. All the other parts explained below also suitably consist of light metal, in particular an aluminum alloy. At their upper ends, the two stands 101, 102 are firmly connected to one another by a cross member 103 and at their lower ends by an upwardly curved rail 104 to form the frame. Furthermore, the stands 101, 102 are provided at their upper ends with pins 108, 109 which have conical bevels 110, 111 on the end face and which can be inserted into the stands of an adjacent frame, not shown, located above them. The outer diameters of the pins 108, 109 and the inner diameters of the stands 101, 102 are matched to one another accordingly. For reinforcement, obliquely extending supports 105 and 106 are welded between the cross member 103 and the stands 101, 102.

Die Traverse 103 trägt mehrere Bohlenhalterungen 107, auf die je nach Breite des Gerüstes und Ausführung der Bohlen eine, zwei oder, wie im vorliegenden Falle, drei Bohlen aufgesteckt werden können. Wie Figur 8 verdeutlicht, be­steht die Traverse aus einem Rechteckhohlprofil. Jede Boh­lenhalterung umgreift die Traverse teilweise mit je zwei seitlichen Klauen 135 und 136 und einem Steg 137, der die beiden Klauen 135 und 136 miteinander verbindet. Ferner be­sitzt jede Bohlenhalterung zwei nach oben ragende Haltezap­fen 138 und 139, die entsprechend angeformt sind und die am oberen Ende konische Verjüngungen 140 und 141 aufweisen. Die Verbindung zwischen den Bohlenhalterungen 107 und der Traverse 103 erfolgt durch Schweißnähte 142.The crossbeam 103 carries a plurality of screed brackets 107, onto which one, two or, as in the present case, three screeds can be attached, depending on the width of the scaffolding and the design of the screeds. As shown in FIG. 8, the traverse consists of a rectangular hollow profile. Each screed bracket partially surrounds the cross member with two lateral claws 135 and 136 and a web 137 which connects the two claws 135 and 136 to one another. Furthermore, each screed holder has two upwardly projecting holding pins 138 and 139, which are molded on accordingly and which have conical tapered portions 140 and 141 at the upper end. The connection between the screed brackets 107 and the cross member 103 is made by welds 142.

Auch die Verbindungen der weiteren oben erläuterten Teile erfolgt entsprechend den Darstellungen der Zeichnungen durch Schweißnähte, die mit den Bezugszeichen 112 bis 119 versehen sind.The connections of the other parts explained above also take place in accordance with the illustrations in the drawings by means of weld seams which are provided with the reference numerals 112 to 119.

Die nach oben hin gewölbte Schiene 104, die besonders deut­lich in Figur 9 zu sehen ist, weist auf der Unterseite ein trapezförmiges mittleres Schienenteil auf. Im übrigen ist die Schiene 104 so angeordnet, daß sie den Spalt zwischen je zwei dicht darunter befindlichen Bohlen abdeckt. Dies wird deutlich, wenn man sich ein weiteres Rahmenteil gemäß Figur 5 oben auf das in Figur 5 dargestellte Rahmenteil aufgesetzt denkt. Es können weitere Sicherungs- und Sonder­ausrüstungen vorgesehen werden, wie beispielsweise der Zap­fen 120.The rail 104, which is curved upwards and can be seen particularly clearly in FIG. 9, has a trapezoidal central rail part on the underside. In addition, the rail 104 is arranged so that it covers the gap between two planks located closely below each. This becomes clear when you think of a further frame part according to FIG. 5 placed on top of the frame part shown in FIG. Additional safety and special equipment can be provided, such as the pin 120.

Eine besonders wichtige Konstruktion zeigen die Figuren 6 und 7, und zwar die Riegelhalterungen 121, die an den Stän­dern 101, 102 auf den Außen- und/oder Innenseiten mit Ab­stand voneinander bzw. übereinander vorgesehen sind, wie in Figur 5 dargestellt ist. Diese Riegelhalterungen weisen ra­dial zu den Ständern 101, 102 verlaufende zylindrische Zap­fen 122 auf, welche einerseits über Zylinderteile 126 mit dem betreffenden Ständer 101, 102 verbunden und anderer­seits mit unsymmetrisch gelagerten Schwenklaschen 125 bzw. Kippstiften versehen sind. Vorteilhafterweise umgreifen die Zylinderteile 126 die Ständer 101, 102 über einen Winkel 127 von etwa 90 Grad. An ihren inneren Zylinderwandenden sind Stützvorsprünge 130 und 131 angeformt, in deren Be­reich die Zylinderteile 125 durch Schweißnähte 128 und 129 mit den Ständern 101, 102 verbunden sind. Zwischen den Stützenvorsprüngen 130, 131 einerseits und jedem Zylinder­teil 126 und dem betreffenden Ständer 101, 102 andererseits ist ein Spalt 132 vorgesehen. Auf diese Weise ergibt sich eine dichte Anlage der Stützenvorsprünge 130, 131 an der Außenoberfläche des betreffenden Ständers 101, 102, so daß besonders dichte und sichere Schweißnähte 128, 129 ausge­führt und die Riegelhalterung 121 insgesamt sehr genau aus­gerichtet und leicht angebracht werden können. Ferner erge­ben sich zu der an den Zapfen angreifenden Last Hebelarme, wodurch die Schweißnähte nur verhältnismäßig gering bela­stet werden. Die Schwenklaschen 125, die aufgrund ihrer un­symmetrischen Ausbildung immer das Bestreben haben, in die vertikale Lage gemäß Figar 6 zu schwenken, sind in vertika­len Schlitzen 123 der zylindrischen Zapfen 122 mittels Spannhülsen 124 gelagert.A particularly important construction is shown in FIGS. 6 and 7, namely the latch holders 121, which are provided on the stands 101, 102 on the outer and / or inner sides at a distance from one another or one above the other, as shown in FIG. These latch holders have cylindrical pins 122 which run radially to the stands 101, 102 and which are connected on the one hand to the relevant stand 101, 102 via cylinder parts 126 and on the other hand are provided with asymmetrically mounted swivel tabs 125 or tilting pins. The cylinder parts 126 advantageously encompass the stands 101, 102 over an angle 127 of approximately 90 degrees. Support projections 130 and 131 are formed on their inner cylinder wall ends, in the area of which the cylinder parts 125 are connected to the stands 101, 102 by welds 128 and 129. A gap 132 is provided between the support projections 130, 131 on the one hand and each cylinder part 126 and the relevant stand 101, 102 on the other hand. In this way, there is a tight contact of the support projections 130, 131 on the outer surface of the stand 101, 102 in question, so that particularly tight and secure welds 128, 129 performed and the latch bracket 121 can be aligned very precisely and easily attached. Furthermore, lever arms result from the load acting on the pin, whereby the weld seams are loaded only comparatively little. The swivel tabs 125, which due to their asymmetrical design always endeavor to pivot into the vertical position according to FIG. 6, are mounted in vertical slots 123 of the cylindrical pins 122 by means of clamping sleeves 124.

Die Riegelhalterungen 121 dienen der Halterung bzw. Befe­stigung der senkrecht zu der Bildebene der Figuren 5 und 6 verlaufenden Riegel, vor allen Dingen der Horizontalriegel 133, die als durchgehende Rohre ausgebildet sein können und mit Abständen voneinander je zwei sich gegenüberliegende Bohrungen aufweisen, und zwar entsprechend den Abständen, mit denen die Gerüstrahmen innerhalb des Gerüstes aufge­stellt werden. Nach Hochklappen der Schwenklasche 125 bzw. eines Kippstiftes in Richtung des Pfeils 143 (Figur 6) um 90 Grad kann man den Horizontalriegel auf den zylindrischen Zapfen 122 aufschieben, so daß der Horizontalriegel 133 nach Zurückklappen der Schwenklasche 125 in die vertikale Lage einfach und sicher gehalten ist. Auf gleiche einfache Weise kann der Horizontalriegel zum Auseinanderbau des Ge­rüstes wieder abgenommen werden. Wenn die Horizontalriegel aus verhältnismäßig kurzen Rohrstücken, z.B. entsprechend dem einfachen, zweifachen oder dreifachen Abstand der Ge­rüstrahmen voneinander, bestehen, kann man auch die Enden der jeweiligen Horizontalriegel auf die Riegelhalterung aufbringen, wobei es unter anderem möglich ist, die Riege­lenden abzuflachen oder mit gelochten Laschen 134 (Figur 5) zu versehen. Wesentliche Vorteile der erfindungsgemäßen Konstruktionen bestehen darin, daß besonders diejenigen Teile, die stark belastet werden, sehr stabil und unbrech­ bar ausgeführt sind und eine sichere Halterung gewährlei­sten.The latch brackets 121 serve to hold or fasten the latches running perpendicular to the image plane of FIGS. 5 and 6, above all the horizontal latches 133, which can be designed as continuous tubes and have two mutually opposite bores at a distance from one another, respectively the distances with which the scaffold frames are set up within the scaffolding. After swiveling up the swivel bracket 125 or a tilting pin in the direction of arrow 143 (FIG. 6) by 90 degrees, the horizontal bar can be pushed onto the cylindrical pin 122, so that the horizontal latch 133 is held simply and securely after the swivel bracket 125 has been folded back into the vertical position is. In the same simple way, the horizontal bar can be removed again to disassemble the scaffolding. If the horizontal bolts consist of relatively short pipe sections, e.g. corresponding to the simple, double or triple spacing of the scaffolding frames from one another, the ends of the respective horizontal bolts can also be attached to the bolt holder, whereby it is possible, among other things, to flatten the bolt ends or with perforated tabs 134 (Figure 5). Significant advantages of the constructions according to the invention are that especially those parts that are heavily loaded are very stable and unbreakable bar and ensure a secure mounting.
