Definitions
- the invention relates to a mobile scaffolding made of prefabricated components, consisting essentially of vertical frame elements composed of stands, horizontal, rectangular, the floor plan of the scaffolding covering platforms, which can be placed on crossbars that can also be used as ladder rungs in the frame elements and with access and limiting Longitudinal and / or transverse rims can be equipped, diagonal longitudinal and / or transverse struts, fixed to the uprights, longitudinal and / or transverse railing and / or intermediate bars and on a horizontal element belonging to a frame element provided at the lower end thereof beam-shaped cross-member attached in pairs castors for moving the scaffolding, which are each attached to the free end of a widening cross member, which is attached to the cross member and can be moved in parallel and the longitudinal axis of which to associated cross-beam is parallel, but preferably aligned with this.
- Scaffolding of this type is often of considerable height and must have sufficient stability when erected have, without the outer, given by the covering platforms dimensions therefore would have to be increased beyond the technologically necessary and permissible for transport. It is therefore common practice and regulated by the relevant regulations that the standing moment of the scaffolding is increased by the paired casters can be pulled apart from their transport position to increase the footprint when setting up the scaffolding.
- the widening trusses serve this purpose.
- the casters cannot be shifted in a direction perpendicular to the one specified by the widening crossbars, without additional extension crossbars having to be inserted and the entire arrangement having to be considerably more complicated. Nevertheless, the expansion of the stand area in this (longitudinal) direction is actually desirable.
- the invention is therefore based on the task of designing a mobile scaffolding of the type specified at the outset with simple means so that the stand area can be expanded during operation in relation to the permissible and permissible floor plan in two mutually perpendicular, horizontal directions, without requiring considerable effort.
- each of the crossbeams has two sections which are provided at an angle to one another and which, on the one hand, are arranged symmetrically and obliquely inwards in relation to one another in the plan of the scaffolding, and on the other hand each have one of the widening crossbars which are inclined outwards in the longitudinal axis of the respective one Part is slidable.
- the angled sections can be formed abutting or connected to one another by at least one further section of the crossbar, preferably parallel to the crossbars, and for example screwed or welded to one another or by means of at least one angled bracket; other configurations are possible. Regardless of the special design, it is only necessary to ensure in any case that the connection points of the sections are securely formed; however, this is a subordinate problem with the machine elements which are customarily available in the industry and the state of the art in welding technology, which can be worked on without difficulty by the expert.
- a particularly advantageous invention is that the sections and widening traverses are designed in cross section as a preferably rectangular hollow profile piece.
- Such profiles are, for example, high-quality and inexpensive to produce in the extrusion process; the non-round cross-section is favorable for connections, bearing points etc. and saves an anti-twist device in the longitudinal axis.
- a vertical piece of pipe is provided at the outer ends of the widening traverses for mounting the associated castor, which can also be designed to be replaceable and adjustable in height by support feet.
- the invention is explained below with reference to the drawing using an exemplary embodiment.
- the single figure shows a scaffolding according to the invention in the overall overview in a spatial representation.
- a mobile scaffolding according to the invention consists first of all of a system of vertical frame elements 1 consisting of parallel stands 11, wherein a plurality of frame elements 1 can be connected one above the other, for example by providing plug pins on the (upper) ends of their stands 11, onto which the (lower) ends of the next higher stand 11 can be placed if they consist of (circular cylindrical) tubes as usual.
- the vertical frame elements 1 are connected to one another by (here) a horizontal covering platform 2 which rests on crossbars 12 and is locked to them in a suitable manner.
- the topping stage 2 can be equipped with a step-through, which can also be closed by a flap if necessary.
- the access allows the cross bars 12 welded in a narrow grid between the uprights 11 to be used as ladder rungs and to dispense with separate stairs.
- the details are known in the art and are only partially shown in the drawing.
- the scaffolding is sufficiently stiffened by means of diagonal longitudinal struts 13; Of course, cross braces can also be provided, but are not needed here because of the tight sequence of the welded cross bars 12.
- the longitudinal struts 13 are attached to the crossbars 12.
- Railing bars can be provided for safety; the covering platform 2 can be limited in the foot area by longitudinal and transverse rims. The details are unrelated to the invention and are omitted from the drawing.
- Casters 3 essentially allow the scaffolding to be moved in its longitudinal direction T and are supported with a bearing in a vertical pipe section 14.
- Widening traverses 15 are designed in cross-section with a (high) rectangular hollow profile, which can be inserted into a cross-beam 16 that is also (high) rectangular in cross-section
- the crossbar 16 consists of two sections 16a, 16b which are connected to one another at two abutting ends; In the drawing, screw connections S are indicated, which rigidly connect these ends to one another by means of an angled lug inserted into the sections 16a, 16b. At the other end, a lower end of one of the stands 11 is fastened and the associated widening cross member 15 is mounted for longitudinal displacement; this longitudinal mobility can be locked in a suitable manner.
- the drawing clearly shows the arrangement of the sections 16a, 16b; they are - in plan view - arranged obliquely inwards of the scaffolding on the uprights 11, so that the widening cross members 15 are displaced obliquely outwards and thus increase the footprint of the scaffolding in length and width.
Abstract
Description
Die Erfindung betrifft ein fahrbares Baugerüst aus vorgefertigten Bauteilen, im wesentlichen bestehend aus vertikalen, aus Ständern zusammengesetzten Rahmenelementen, horizontalen, rechteckigen, den Grundriß des Baugerüstes bestimmenden Belagbühnen, die auf gegebenenfalls auch als Leitersprossen verwendbaren Querriegeln in den Rahmenelementen auflegbar sind und mit Durchstiegen und begrenzenden Längs- und/oder Querborden ausgestattet sein können, diagonalen Längs- und/oder Querverstrebungen, an den Ständern befestigten, längs und/oder quer verlaufenden Geländer- und/oder Zwischenholmen und an einer zu jeweils einem Rahmenelement gehörigen, an deren unterem Ende vorgesehenen waagerechten balkenförmigen Quertraverse paarweise angebrachten Fahrrollen zum Verfahren des Baugerüstes, die jeweils an dem freien Ende einer Verbreiterungstraverse befestigt sind, welche entlang der Quertraverse an dieser befestigt und parallel verschiebbar ist und deren Längsachse derjenigen der zugehörigen Quertraverse parallel ist, vorzugsweise mit dieser aber fluchtet.The invention relates to a mobile scaffolding made of prefabricated components, consisting essentially of vertical frame elements composed of stands, horizontal, rectangular, the floor plan of the scaffolding covering platforms, which can be placed on crossbars that can also be used as ladder rungs in the frame elements and with access and limiting Longitudinal and / or transverse rims can be equipped, diagonal longitudinal and / or transverse struts, fixed to the uprights, longitudinal and / or transverse railing and / or intermediate bars and on a horizontal element belonging to a frame element provided at the lower end thereof beam-shaped cross-member attached in pairs castors for moving the scaffolding, which are each attached to the free end of a widening cross member, which is attached to the cross member and can be moved in parallel and the longitudinal axis of which to associated cross-beam is parallel, but preferably aligned with this.
Baugerüste dieser Art sind von oft beträchtlicher Höhe und müssen bei ihrer Aufstellung eine genügende Standfestigkeit aufweisen, ohne daß die äußeren, durch die Belagbühnen vorgegebenen Grundriß-Abmessungen deshalb über das technologisch erforderliche und für einen Transport zulässige Maß hinaus vergrößert werden müßten. Es ist deshalb gängige Praxis und durch die einschlägigen Vorschriften geregelt, daß das Standmoment der Baugerüste vergrößert wird, indem die paarweise angeordneten Fahrrollen bei der Aufstellung des Baugerüstes aus ihrer Transportstellung standflächendvergrößernd auseinandergezogen werden können. Dazu dienen die Verbreiterungstraversen. Die Fahrrollen können dabei allerdings nicht auch noch in einer Richtung senkrecht zu der durch die Verbreiterungstraversen vorgegebenen verschoben werden, ohne daß dafür zusätzliche Verlängerungstraversen eingefügt werden müßten und die gesamte Anordnung wesentlich komplizierter ausfallen müßte. Gleichwohl ist aber die Ausdehnung der Standfläche auch in dieser (Längs-) Richtung eigentlich erwünscht.Scaffolding of this type is often of considerable height and must have sufficient stability when erected have, without the outer, given by the covering platforms dimensions therefore would have to be increased beyond the technologically necessary and permissible for transport. It is therefore common practice and regulated by the relevant regulations that the standing moment of the scaffolding is increased by the paired casters can be pulled apart from their transport position to increase the footprint when setting up the scaffolding. The widening trusses serve this purpose. However, the casters cannot be shifted in a direction perpendicular to the one specified by the widening crossbars, without additional extension crossbars having to be inserted and the entire arrangement having to be considerably more complicated. Nevertheless, the expansion of the stand area in this (longitudinal) direction is actually desirable.
Die Erfindung hat sich deshalb die Aufgabe gestellt, ein fahrbares Baugerüst der eingangs näher bezeichneten Art mit einfachen Mitteln so zu gestalten, daß die Standfläche während des Betriebes gegenüber dem für den Transport maßgeblichen und zulässigen Grundriß in zwei aufeinander senkrechten, waagerechten Richtungen ausgedehnt werden kann, ohne daß es dafür eines erheblichen Aufwandes bedürfte.The invention is therefore based on the task of designing a mobile scaffolding of the type specified at the outset with simple means so that the stand area can be expanded during operation in relation to the permissible and permissible floor plan in two mutually perpendicular, horizontal directions, without requiring considerable effort.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß jede der Quertraversen zwei zueinander abgewinkelt vorgesehene Teilstücke aufweist, die im Grundriß des Baugerüstes einerseits zueinander symmetrisch und schräg nach innen gerichtet angeordnet sind und andererseits jeweils eine der Verbreiterungstraversen aufweisen, die schräg nach außen in der Längsachse des jeweiligen Teilstückes verschiebbar ist.According to the invention, the object is achieved in that each of the crossbeams has two sections which are provided at an angle to one another and which, on the one hand, are arranged symmetrically and obliquely inwards in relation to one another in the plan of the scaffolding, and on the other hand each have one of the widening crossbars which are inclined outwards in the longitudinal axis of the respective one Part is slidable.
Auf diese einfache Weise wird ein gesondertes Verlängerungssystem quer zu einem bereits vorhandenen Verbreiterungssystem mit dem dafür erforderlichen baulichen Aufwand vermieden, trotzdem aber die Aufgabenstellung in für derartige Baugerüste ausreichendem Umfang verwirklicht. Je nachdem, in welchem Maße die Teilstücke abgewinkelt sind, sind nun die Standfläche und auch die Standsicherheit des Baugerüstes in der einen oder anderen Richtung mehr oder weniger umfangreich vergrößerbar. Die Anordnung hängt dabei nicht von der sonstigen Konstruktion der beteiligten Bauelemente ab und ist für ganz verschiedene Systeme gleichermaßen geeignet.In this simple way, a separate extension system is made transversely to an existing widening system with the constructional effort required for this avoided, but nevertheless accomplished the task to a sufficient extent for such scaffolding. Depending on the extent to which the sections are angled, the footprint and the stability of the scaffolding can now be enlarged to a greater or lesser extent in one direction or the other. The arrangement does not depend on the other construction of the components involved and is equally suitable for very different systems.
Die abgewinkelt vorgesehenen Teilstücke können aneinanderstoßend ausgebildet oder durch mindestens ein weiteres, vorzugsweise zu den Querriegeln paralleles Teilstück der Quertraverse miteinander verbunden sein und beispielsweise miteinander oder mittels mindestens einer abgewinkelten Lasche verschraubt oder auch miteinander verschweißt werden; andere Ausgestaltungen sind möglich. Unabhängig von der speziellen Gestaltung ist in jedem Falle lediglich dafür zu sorgen, daß die Verbindungsstellen der Teilstücke sicher ausgebildet werden; dies ist jedoch bei den branchenüblich verfügbaren Maschinenelementen und dem Stand der Schweißtechnik ein untergeordnetes, von dem Fachmann ohne Mühe zu bearbeitendes Problem.The angled sections can be formed abutting or connected to one another by at least one further section of the crossbar, preferably parallel to the crossbars, and for example screwed or welded to one another or by means of at least one angled bracket; other configurations are possible. Regardless of the special design, it is only necessary to ensure in any case that the connection points of the sections are securely formed; however, this is a subordinate problem with the machine elements which are customarily available in the industry and the state of the art in welding technology, which can be worked on without difficulty by the expert.
Eine besonders vorteilhafte Erfindung besteht darin, daß die Teilstücke und Verbreiterungstraversen im Querschnitt als vorzugsweise rechteckiges Hohlprofilstück ausgebildet sind. Derartige Profile sind beispielsweise im Strangpreßverfahren hochwertig und billig herstellbar; der nichtrunde Querschnitt ist für Anschlüsse, Lagerstellen usw. günstig und erspart eine Verdrehsicherung in der Längsachse.A particularly advantageous invention is that the sections and widening traverses are designed in cross section as a preferably rectangular hollow profile piece. Such profiles are, for example, high-quality and inexpensive to produce in the extrusion process; the non-round cross-section is favorable for connections, bearing points etc. and saves an anti-twist device in the longitudinal axis.
Es ist zweckmäßig, wenn an den äußeren Enden der Verbreiterungstraversen jeweils ein senkrechtes Rohrstück zur Lagerung der zugehörigen Fahrrolle vorgesehen ist, die im übrigen auch durch Stützfüße ersetzbar und höhenverstellbar ausgebildet sein können.It is expedient if a vertical piece of pipe is provided at the outer ends of the widening traverses for mounting the associated castor, which can also be designed to be replaceable and adjustable in height by support feet.
Die Erfindung wird nachstehend an Hand der Zeichnung an einem Ausführungsbeispiel näher erläutert. Die einzige Figur zeigt ein erfindungsgemäßes Baugerüst in der Gesamt-Übersicht in räumlicher Darstellung.The invention is explained below with reference to the drawing using an exemplary embodiment. The single figure shows a scaffolding according to the invention in the overall overview in a spatial representation.
Ein fahrbares Baugerüst nach der Erfindung besteht zunächst aus einem System vertikaler Rahmenelemente 1 aus parallelen Ständern 11, wobei mehrere Rahmenelemente 1 übereinander anschließbar sind, beispielsweise indem an den (oberen) Enden ihrer Ständer 11 Steckbolzen vorgesehen sind, auf welche die (unteren) Enden der nächsthöheren Ständer 11 aufsetzbar sind, wenn sie wie üblich aus (kreiszylindrischen) Rohren bestehen. Die vertikalen Rahmenelemente 1 sind durch (hier) eine waagerechte Belagbühne 2 miteinander verbunden, die auf Querriegeln 12 aufliegt und an diesen in geeigneter Weise verriegelt ist. Die Belagbühne 2 kann mit einem Durchstieg ausgerüstet sein, der gegebenenfalls auch mittels einer Klappe verschließbar ausführbar ist. Der Durchstieg gestattet es, die in engem Rastermaß zwischen den Ständern 11 angeschweißten Querriegel 12 als Leitersprossen zu verwenden und auf gesonderte Treppen zu verzichten. Die Einzelheiten sind fachbekannt und in der Zeichnung nur teilweise ausgeführt.A mobile scaffolding according to the invention consists first of all of a system of
Das Baugerüst wird mittels diagonaler Längsverstrebungen 13 genügend versteift; selbstverständlich können darüberhinaus auch Querverstrebungen vorgesehen sein, die aber hier wegen der dichten Folge der verschweißten Querriegel 12 nicht benötigt werden. Die Längsverstrebungen 13 sind an den Querriegeln 12 befestigt.The scaffolding is sufficiently stiffened by means of diagonal
Zur Sicherheit können Geländerholme vorgesehen sein; die Belagbühne 2 kann im Fußbereich von Längs- und Querborden begrenzt sein. Die Einzelheiten stehen mit der Erfindung in keinem Zusammenhang und sind in der Zeichnung weggelassen.Railing bars can be provided for safety; the covering platform 2 can be limited in the foot area by longitudinal and transverse rims. The details are unrelated to the invention and are omitted from the drawing.
Fahrrollen 3 gestatten im wesentlichen die Verfahrbarkeit des Baugerüstes in dessen Längsrichtung T und sind mit einer Lagerung in einem senkrechten Rohrstück 14 gelagert.
Verbreiterungstraversen 15 sind im Querschnitt mit einem (hoch-) rechteckigen Hohlprofil ausgeführt, das jeweils in eine im Querschnitt ebenfalls (hoch-)rechteckige Quertraverse 16 einschiebbar ist
Die Quertraverse 16 besteht aus zwei Teilstücken 16a,16b, die an zwei aneinander stoßenden Enden miteinander verbunden sind; in der Zeichnung sind Schraubverbindungen S angedeutet, welche diese Enden durch eine in die Teilstücke 16a,16b eingeschobene, abgewinkelte Lasche starr miteinander verbinden. Am anderen Ende ist jeweils ein unteres Ende eines der Ständer 11 befestigt und die zugehörige Verbreiterungstraverse 15 längsverschiebbar gelagert; diese Längsbeweglichkeit kann in geeigneter Weise arretiert werden.The
Die Zeichnung läßt ohne weiteres die Anordnung der Teilstücke 16a,16b erkennen; sie sind - in der Draufsicht - schräg nach innen des Baugerüstes gerichtet an den Ständern 11 angeordnet, so daß die Verbreiterungstraversen 15 schräg nach außen verschoben werden sind und so die Standfläche des Baugerüstes in Länge und Breite vergrößern.The drawing clearly shows the arrangement of the
