Definitions
- the invention relates to a method for converting an Ar beitsgerüstes, which is suspended from a bridge and the bridge in the longitudinal direction movable to a bridge pillar, in which the work scaffolding on ropes od. Dg 'l. is pivotable, and a device for use in the inspection and renovation of bridges, with a work scaffold that is suspended from the bridge and movable in the longitudinal direction of the bridge, the work scaffold suspended from the bridge and at least at one end via a rope or the like.
- a generic work scaffold that is intended to solve these problems is known from DE-C 30 04 450.
- the mobile hanging scaffold known from DE-C 30 04 450 has the disadvantage that at least three working scaffold units arranged one behind the other in the longitudinal direction of the bridge must be provided in order, for example, to be able to drive around a bridge pier.
- These work scaffold units must then be made very solid, since considerable torsional forces occur when the outer scaffold units are opened.
- Another disadvantage is that the scaffolding parts are folded up over ropes, as described in DE-C 30 04 450 ben are arranged. Due to the short force arm, very high forces act on the rope and the scaffolding. This is especially true if the swing-down frame part is long, which must be the case with wide bridges.
- the object of the invention is to provide a method and a device which are technically simple and in which the disassembly and assembly of the work scaffold and in particular the relocation of the work scaffold by bridge piers can be carried out simply and quickly.
- a generic method which is characterized in that the work scaffold at least at one end via a rope or the like, which runs to the longitudinal edge of the bridge, the end of the work scaffold to the this is pivoted, lies opposite, is lowered, while it is pivoted about the other end, until it only hangs at the other end, that the rope is detached from the work scaffold, that the work scaffold in the longitudinal direction of the bridge on Bridge pier is driven past, and that the rope is attached to the scaffolding again and finally the scaffolding is swung up again.
- a work scaffold can be conveyed around a bridge pier within a very short time and with very little technical effort and effort.
- the work scaffold is separated into two parts and the ends of the work scaffold adjacent to the separation point are lowered by means of ropes running to the opposite longitudinal edge of the bridge.
- This embodiment of the method is particularly suitable when the bridge is not high enough to allow the entire length of the work scaffold to hang down in front of a bridge, since the two parts of the work scaffold are only half as long, for example are when the work frame is divided exactly in the middle.
- the device according to the invention for use in the inspection and renovation of bridges is characterized in that the other end of the work scaffold or the like, which runs to the longitudinal edge of the bridge, the end of the work scaffold about which it is pivoted is, opposite, is lowerable.
- the device according to the invention has the considerable advantage over the prior art known from DE-C 30 04 450 that the forces acting on the rope or the like, via which the pivoting and lifting of the work scaffold is accomplished, are not significantly greater are in the working position when the work scaffold is in operation, since the rope or the like is guided to the opposite longitudinal edge of the bridge. Furthermore, it is not necessary to provide more than one work scaffold in order to be able to drive around bridge pillars or the like. Both advantages have the effect that the device according to the invention is technically much simpler in construction than that of the prior art and is consequently also considerably lighter.
- the work scaffold is suspended from the bridge at both ends by ropes with cable winches, it is possible to lower the work scaffold at each of the two ends, which is particularly advantageous then is when an end cannot be lowered for any reason.
- the work scaffold in one embodiment of the invention, which is characterized in that the work scaffold can be separated into two parts and that each part can be lowered at its separation point, which is connected by a rope or the like, to the opposite longitudinal edge of the bridge runs, the work scaffold is separated at any point, but preferably in the middle, and the parts are lowered at their separation point in any way.
- this embodiment is mentioned, particularly advantageous if, for example, the bridge is not high enough to allow the entire work scaffold to hang freely down at one end.
- Another advantage in connection with this embodiment is that the entire weight of the work scaffold does not hang at one end, as a result of which a very strong one-sided load on the device can be avoided.
- the ropes stretched from the central area of one part to the opposite longitudinal edge of the bridge allow the two parts of the scaffolding to be pivoted around their outer ends and left in the middle until they hang freely down at their ends.
- the ropes can then be released from the separation points and the pillar can be easily bypassed.
- the ropes are fastened again at the separation points and the two parts of the scaffolding are pulled up again, whereupon the scaffolding in the middle area can be connected again and work on the scaffolding can be continued.
- the device according to the invention can be adapted particularly easily to the particular circumstances on the bridge.
- a further preferred embodiment of the invention is characterized in that the carriages are supported by at least one vertical bearing and one horizontal bearing in the region of the longitudinal edge of the bridge, and that the carriage on the scaffolding part projecting downward into the area of the working scaffold is essentially horizontal aligned cantilever is provided, which projects under the longitudinal edge of the bridge and at the free end of which the cables are arranged, it being further possible to provide for the cantilever to be horizontally displaceable and / or for the free end to be positioned under the vertical bearing of the carriage .
- the material conveyor track can be designed in many different ways. According to one embodiment of the invention e.g. it should be provided that the material conveyor track has a channel in which the removal material and the like can be washed away, and that the material conveyor track is inclined with respect to the horizontal. In this case, the waste water obtained during removal can be used immediately as alluvial water. As stated, it is advantageous if the material conveyor path is inclined with respect to the horizontal, which facilitates washing away.
- the material conveyor track can have a conveyor belt which is known per se and is driven, for example, by an electric motor.
- the material conveyor track has a trough with a scraper conveyor or the like, with which a particularly problem-free conveyance is possible.
- a grating is arranged above the trough, preferably adjustable in height. Since the device according to the invention is expandable and expandable to suit the particular circumstances, i.e. to be able to adapt the shape of the bridge underside, it is advantageous if the grating is height-adjustable so that the bridge underside can be reached by the staff at any height of the work scaffold.
- the scaffold projecting downward into the area of the work scaffold has at least one container for receiving the removal material and the like.
- the wagon which can be moved in the area of the edge beam of a bridge or breakdown lane and consequently does not necessarily have to block the road, takes over the material to be removed in its container. Like., whereupon this can be conveyed along the bridge to a point where disposal is possible. Disposal is possible, for example, directly above the scaffolding of the car using suitable devices.
- the container is passed through a grating into an area for receiving the solid removal material and an area for receiving the Remediation of water or the like is separated.
- rails are provided in the region of the top of the work scaffold, on which at least one nozzle for pressurized water can be moved.
- the course of the rails is adapted to the shape of the bridge bottom view. This offers the advantage that essentially the entire area of the underside of the bridge and, if appropriate, the pillar can be reached by the nozzle and the removal of material by hand is consequently no longer necessary.
