Abstract

In order to inspect and rehabilitate bridges (4), a scaffolding (1) is provided that is suspended from the bridge (4) and can be moved in the longitudinal direction of the bridge (4). In order to move the scaffolding (1) around bridge piers (6) or the like in a particularly easy manner, the scaffolding (1) may be lowered at one of its both ends (16, 17) until it hangs freely downwards and can be moved around the bridge pier (6). It may then be swung up once again by pulling up the lowered end (16, 17). The length of the scaffolding (1) to be swung downwards may be reduced by subdividing the middle area of the scaffolding (1) into two parts (2, 3). Each part (2, 3) may be lowered by means of cables (10) that run from its junction to the opposite edge (15) of the bridge (4), until both parts (2, 3) hang freely downwards and may be moved around the bridge piers (6), then be pulled up once again.

Description

Die Erfindung betrifft ein Verfahren zum Umsetzen eines etwa in der Mitte teilbaren Arbeitsgerüstes, das von einer Brücke abgehängt und in Längsrichtung der Brücke verfahrbar ist, um einen Brückenpfeiler, bei dem das Arbeitsgerüst über Seile od. dgl. abschwenkbar ist und eine Vorrichtung zur Verwendung bei der Inspektion und Sanierung von Brücken, mit einem etwa in der Mitte in zwei Teile trennbaren Arbeitsgerüst, das von der Brücke abgehängt und in Längsrichtung der Brücke verfahrbar ist, wobei die Teile über Seile od. dgl. an ihrer Trennstelle absenkbar sind.The invention relates to a method for implementing a in the middle divisible scaffolding, that of a bridge suspended and in the longitudinal direction of the bridge is movable to a bridge pier, in which the work scaffold over ropes or. The like. is pivotable and a device for use in the inspection and renovation of bridges, with an approximately in the center, which can be separated into two parts, that of the Suspended bridge and movable in the longitudinal direction of the bridge is, the parts on ropes or the like. At their separation point are lowerable.

Bei Brücken, die einen oder mehrere Pfeiler aufweisen, stellt sich das Problem, daß diese die Längsbewegung des Arbeitsgerüstes entlang der Brücke behindern, so daß es oft erforderlich ist, das Arbeitsgerüst abzumontieren, um den Pfeiler herum zu tragen und anschließend wieder aufzubauen. Dies ist jedoch äußerst arbeits- und zeitaufwendig. Besonders schwierig gestaltet sich dies bei Brücken, die z.B. über Flüsse führen, da hier die Arbeitsgerüste nicht über Seile auf den Boden hinuntergelassen und dort um die Pfeiler getragen werden können, so daß das Zerlegen und der Wiederaufbau des Gerüstes von oben über die Brücke erfolgen muß.For bridges that have one or more pillars the problem is that this is the longitudinal movement of the scaffolding hinder along the bridge, so it is often required is to dismantle the scaffolding around the pillar wear and then rebuild. However, this is extremely labor and time consuming. Designed particularly difficult this is the case with bridges, e.g. lead over rivers because here the work scaffolds are not lowered onto the floor by ropes and can be carried around the pillars there, so that the disassembly and reconstruction of the scaffolding from above must take place over the bridge.

Ein gattungsgemäßes Arbeitsgerüst, das diese Probleme lösen soll, ist aus der DE-A-30 04 450 bekannt. Das aus der DE-A-30 04 450 bekannte, fahrbare Hängegerüst weist jedoch den Nachteil auf, daß mindestens drei in Brückenlängsrichtung hintereinander angeordnete Arbeitsgerüsteinheiten vorgesehen sein müssen, um z.B. einen Brückenpfeiler umfahren zu können. Weiters ist das Befahren bzw. Bearbeiten von Bögen bei Bogenbrücken nur schwer möglich oder sogar unmöglich und bei breiten Brückenpfeilern müssen oft wesentlich mehr als drei Gerüsteinheiten vorgesehen sein. Diese Arbeitsgerüsteinheiten müssen dann sehr massiv ausgeführt werden, da erhebliche Torsionskräfte auftreten, wenn die äußeren Gerüsteinheiten geöffnet werden. Ein weiterer Nachteil ist das Hochklappen der Gerüstteile über Seile, die wie in der DE-A 30 04 450 beschrieben angeordnet sind. Durch den kurzen Kraftarm wirken nämlich sehr hohe Kräfte auf das Seil und das Gerüst. Dies ganz besonders, wenn der abschwenkbare Gerüstteil lang ist, was bei breiten Brücken der Fall sein muß.A generic work framework that solves these problems is known from DE-A-30 04 450. That from DE-A-30 04 450 known, mobile hanging scaffolding has the disadvantage on that at least three in a row in the longitudinal direction of the bridge arranged work scaffold units can be provided need to e.g. to be able to drive around a bridge pier. Furthermore is the driving or processing of arches in arch bridges hardly possible or even impossible and with wide ones Bridge piers often have to have significantly more than three Scaffolding units can be provided. These scaffolding units must then be carried out very solidly, since considerable torsional forces occur when the outer scaffolding units open will. Another disadvantage is the folding up of the scaffolding parts About ropes as described in DE-A 30 04 450 are arranged. Because of the short power arm very high forces on the rope and the scaffold. This especially if the swing-down scaffold part is long, which at wide bridges must be the case.

Aus der FR-A-2 650 815 und der DE-B-1 236 546 sind Vorrichtungen bekannt, bei denen ein einteiliges Arbeitsgerüst quer unter einer Brücke angeordnet und über Seile von dieser abgehängt ist. Das Arbeitsgerüst kann über ein Seil an einem Ende abgeschwenkt werden, bis es am anderen Seil frei nach unten hängt, worauf das Arbeitsgerüst um einen Brückenpfeiler od.dgl. gefahren werden kann.Devices are known from FR-A-2 650 815 and DE-B-1 236 546 known in which a one-piece work scaffold across arranged under a bridge and suspended from it by ropes is. The scaffolding can be attached to a rope at one end be pivoted down until it is free on the other rope depends on what the scaffolding around a bridge pier or the like. can be driven.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung anzugeben, die technisch einfach sind und bei denen das Zerlegen und Zusammenbauen des Arbeitsgerüstes und insbesondere das Umsetzen des Arbeitsgerüstes um Brückenpfeiler einfach und schnell durchgeführt werden kann.The object of the invention is a method and an apparatus to specify, which are technically simple and for which the Disassembling and assembling the scaffolding and in particular the transfer of the scaffolding around bridge piers is easy and can be done quickly.

Gelöst wird diese Aufgabe gemäß der Erfindung durch ein gattungsgemäßes Verfahren, das dadurch gekennzeichnet ist, daß nach dem Trennen des Arbeitsgerüstes in zwei Teile die der Trennstelle benachbarten Enden des Arbeitsgerüstes über zum gegenüberliegenden Längsrand der Brücke verlaufende Seile abgesenkt werden, während sie um die äußeren Enden geschwenkt werden, bis sie nur mehr an den äußeren Enden hängen, daß die Seile vom Arbeitsgerüst gelöst werden, daß anschließend die Teile in Längsrichtung der Brücke am Brückenpfeiler vorbeigefahren werden, und daß die Seile wieder am Arbeitsgerüst befestigt und schließlich die Teile wieder hochgeschwenkt und miteinander verbunden werden.This object is achieved according to the invention by a generic Process characterized in that after separating the scaffolding into two parts the Separation point adjacent ends of the scaffold over to Ropes running opposite the longitudinal edge of the bridge be lowered while being pivoted around the outer ends until they just hang on the outer ends that the Ropes are loosened from the scaffolding that the Parts in the longitudinal direction of the bridge pass the bridge pier and that the ropes are reattached to the scaffolding and finally the parts swiveled up again and be connected to each other.

Durch das erfindungsgemäße Verfahren kann ein Arbeitsgerüst innerhalb kürzester Zeit und mit sehr geringem technischen Aufwand und Arbeitsaufwand um einen Brückenpfeiler gefördert werden.A work scaffold can be created by the method according to the invention within a very short time and with very little technical Funded effort and workload around a bridge pillar will.

Das Verfahren ist besonders auch dann geeignet, wenn die Brücke nicht ausreichend hoch ist, um das Arbeitsgerüst in seiner vollen Länge von einer Brücke nach unten hängen zu lassen, wie dies bei der FR-A-26 50 815 und der DE-B-12 36 546 der Fall ist, da die beiden Teile des Arbeitsgerüstes beispielsweise nur mehr halb so lang sind, wenn das Arbeitsgerüst genau in der Mitte geteilt wird.The method is particularly suitable even if the Bridge is not high enough to support the scaffolding to hang down its full length from a bridge can, as is the case with FR-A-26 50 815 and DE-B-12 36 546 the case is because the two parts of the scaffolding, for example are only half as long when the scaffolding divided exactly in the middle.

Die gestellte Aufgabe wird weiters erfindungsgemäß bei einer gattungsgemäßen Vorrichtung dadurch gelöst, daß jeder Teil an seiner Trennstelle mit einem Seil od. dgl. verbunden ist, das zum gegenüberliegenden Längsrand der Brücke verläuft. Mit Hilfe der erfindungsgemäßen Vorrichtung kann das erfindungsgemäße Verfahren besonders einfach durchgeführt werden, wobei sich ebenfalls die weiter oben gegenüber dem Stand der Technik angeführten Vorteile ergeben.The task is also inventively at a Generic device solved in that each part its separation point is connected with a rope or the like runs to the opposite longitudinal edge of the bridge. With The device according to the invention can be used with the device according to the invention Process can be carried out particularly easily, wherein also the above compared to the prior art advantages listed.

Insbesondere weist die erfindungsgemäße Vorrichtung gegenüber dem aus der DE-A 30 04 450 bekannten Stand der Technik den erheblichen Vorteil auf, daß die auf die Seile od. dgl., über welche das Verschwenken und Hochziehen des Arbeitsgerüstes bewerkstelligt wird, wirkenden Kräfte nicht wesentlich größer sind als beim Betrieb des Arbeitsgerüstes in der Arbeitsstellung, da das Seil od. dgl. zum gegenüberliegenden Längsrand der Brücke geführt wird. Überdies ist es nicht erforderlich, mehr als ein Arbeitsgerüst vorzusehen, um Brückenpfeiler od. dgl. umfahren zu können. Beide Vorteile wirken sich dahingehend aus, daß die erfindungsgemäße Vorrichtung technisch viel einfacher aufgebaut ist als die des Standes der Technik und in der Folge auch wesentlich leichter ist.In particular, the device according to the invention faces the prior art known from DE-A 30 04 450 considerable advantage that that on the ropes or the like. About which is the pivoting and lifting of the scaffolding is accomplished, acting forces are not significantly greater are in the working position when operating the scaffolding, since the rope or the like to the opposite longitudinal edge the bridge is led. Furthermore, it is not necessary to provide more than one scaffolding to bridge pillars or To be able to drive around. Both advantages have an effect from that the device according to the invention technically much is constructed more simply than that of the prior art and in which is also much easier.

Die Erfindung ist, wie bereits erwähnt, besonders dann vorteilhaft, wenn z.B. die Brücke nicht hoch genug ist, um das gesamte Arbeitsgerüst an einem Ende frei nach unten hängen zu lassen. Ein weiterer Vorteil der Erfindung ist, daß nicht das gesamte Gewicht des Arbeitsgerüstes an einem Ende hängt, wodurch eine sehr starke einseitige Belastung der Vorrichtung vermieden werden kann.As already mentioned, the invention is particularly advantageous if e.g. the bridge is not high enough to do that entire scaffolding hanging freely down at one end to let. Another advantage of the invention is that not total weight of the scaffolding hangs on one end, causing a very strong one-sided load on the device can be avoided.

Durch die Seile, die vom Mittelbereich eines Teiles zum gegenüberliegenden Längsrand der Brücke gespannt sind, können die beiden Teile des Arbeitsgerüstes um ihre äußeren Enden verschwenkt und in der Mitte nach unten gelassen werden, bis sie an ihren Enden frei nach unten hängen. Die Seile können anschließend von den Trennstellen gelöst und der Pfeiler auf einfache Weise umfahren werden. Nach dem Pfeiler werden die Seile wieder an den Trennstellen befestigt und die beiden Teile des Arbeitsgerüstes wieder nach oben gezogen, worauf das Arbeitsgerüst im Mittelbereich wieder verbunden und die Arbeit am Gerüst fortgesetzt werden kann.Through the ropes that run from the central area of one part to the opposite Longitudinal edge of the bridge can be stretched the two parts of the scaffolding around their outer ends pivoted and let down in the middle until hang them freely down at their ends. The ropes can then released from the separation points and the pillar open be easily circumvented.
