Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • each part its separation point is connected with a rope or the like runs to the opposite longitudinal edge of the bridge.
  • Process can be carried out particularly easily, wherein also the above compared to the prior art advantages listed.

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.
  • 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.
