Definitions

  • the invention relates to a lifting scaffold with a plurality of scaffolding masts, which stand on at least one platform and can be extended in sections, between which elevating platforms are arranged at different heights, the scaffolding masts being fastened to the building facade by means of several holding supports.
  • a scaffold for repair work on facades and eaves which has a walkable scaffold bridge between two mobile masts, the scaffold bridge at work height on rails or trusses attached there can be moved towards the facade.
  • DE-OS 31 14 602 describes a device for work scaffolding with a lifting and lowering work platform with associated safety device.
  • the work platform is arranged between four recessed guide rails and connected to the guide rails on both sides by a lifting mechanism and a suspension.
  • a support bar is arranged on both sides of the work platform, with the help of which the work platform is opened is placed on the scaffolding towers.
  • Drop pawls are arranged on the support bar, which prevents the working platform from falling by snapping into the recesses in the guide rails when the chain of the lifting mechanism breaks.
  • the aerial work platform with a height-adjustable work platform connected to a frame has a work platform with at least two cross beams which are arranged at a distance from one another and can be connected to one another by longitudinal beams and which are provided with guide members via which the cross beams are each adjustable in height on or in a stand.
  • the invention has for its object to provide a mast of the type mentioned in such a way that the scaffold itself builds up and dismantles by the scaffold's own facilities, so that comparatively few operators are required to build a relatively large scaffold.
  • a scaffold mast has at least one support profile, on which at least one toothed rack is provided on the outside and one toothed rack is provided on the inside, on the driving platforms, gears and drives for the gears running in the outer toothed racks and on one of the support profiles connectable slide module with gears and drives are provided for the gears running in the inner racks and that current rails are provided on the scaffold mast and pantographs on the connectable driving platforms and the slide module.

  • the driving platform railing facing the facade is to be used to extend the stage floor to the facade.
  • An electric or electrohydraulic drive is expediently provided on the slide for the gearwheels running on the inner toothed racks.
  • the mast can be designed so that the driving platforms have electrical or electro-hydraulic drives for driving the gear wheels.
  • At least one gear wheel may be provided to prevent the carriage and the platform from falling, or to be equipped with a device for this purpose.
  • the first driving platform can be inserted between the scaffolding masts and, to put on the next scaffolding mast shot, move up to the upper end of the scaffolding masts that are already standing.
  • a fitter traveling in the driving platform is able to attach the next raised scaffold mast shot to the already standing scaffold mast and to the facade. After at least two scaffolding mast shots have been raised, the fitter can drive the platform to the end point of the previously scaffolded masts and wait for the next scaffolding mast shot to be raised there for further extension. With an additional fitter to pick up the mast parts on the floor or on the Two fitters are therefore sufficient to quickly cover large facade areas with mobile scaffolding.
  • stage floor is created by folding the railing on the facade side of the driving platform towards the stage floor, which fills the space between the facade and the stage.
  • Any number of lifting platforms can be moved independently of one another along the scaffolding masts between the individual scaffolding masts. Via the pantographs on the scaffolding mast, the driving platforms can be equipped with electricity for the tools of the fitters.
  • the length of the platform between the masts can be freely selected using individually connected platform segments.
  • the slide can be equipped with additional functions by means of several interchangeable modules, for example a crane boom, which can transport large and heavy components to the roof similar to an otherwise usual construction crane when a scaffolding mast extends above the roof, or one Passenger and / or material lift, which can not only move fitters and material between the individual driving platforms onto the roof, but can also be swung into the building or into the building through the openings in the building.
  • a crane boom which can transport large and heavy components to the roof similar to an otherwise usual construction crane when a scaffolding mast extends above the roof
