Definitions
- the invention relates to a hanging scaffolding to be attached to a roof, in particular in front of it, which has trusses provided with walkable coverings such as planks, gratings or the like, for example 3-point trusses, preferably 4-point trusses.
- Hanging scaffolding can be found where conventional scaffolding cannot be erected, for example on bridges, towers, such as the ones on the Cologne Cathedral at the time, or the like.
- Grid-like 3-point trusses or preferably 4-point trusses are used, which are characterized by their low weight and high stability.
- the scaffolding of a building for work in the area of the roof ridge of a gable roof and in particular of towers such as church towers for work in the area of the spire is expensive, time-consuming and material-intensive. This is where the invention comes in, in that it makes available a suspended scaffold that can be used very quickly with a comparatively small amount of material.
- the suspended scaffolding according to the invention can be largely completed on a floor to then be brought into a working position by a crane, for example.
- the suspended scaffold is brought into the working position, in possibly pre-assembled individual parts, by means of a cable-stayed cableway, which is fixed to the building and anchored to the ground.
- a cable-stayed cableway which is fixed to the building and anchored to the ground.
- the supports are anchored to the building.
- the supports can also be anchored in the masonry of a building, but attachment to the beams of the roof truss, in particular to rafters, is preferred.
- the advantage is that such a rafter can be interspersed with carriage bolts, which allow it to be fixed securely.
- the roof pitch and the supports then form an upwardly open V when viewed from the side.
- the hanging scaffolding is further secured by the measure that trusses are anchored to the building with scaffolding anchors on the roof side, again preferably to the beams of the roof truss.
- the traverses form a ring shape, for example an ellipse or a circle, or a polygon, enclosing the roof or a spire.
- a tower such as a cross, a rooster or a weathervane of a church tower, which is enclosed by the hanging scaffold, can be serviced in a simple and cost-effective manner.
- booms are connected to trusses at right angles facing away from the roof, the free ends of which are gripped from underneath by the supports.
- the outriggers are expediently designed like the trusses, preferably as 4-point trusses. A stable connection of the cantilevers to the trusses can then be carried out in a simple manner since, for example, clamps from a modular system can be used as a rule.
- This measure also has the advantage that the angle between the roof pitch and the supports is increased. This measure increases the stability of the working platform as a whole.
- the load-bearing capacity and the stability of the work platform can be further increased by the measure if the connections of outriggers to trusses of second supports are reached under.
- the fixing of the first and the second support in the building is preferably carried out directly next to or one above the other. If the second support runs parallel to the roof pitch, the two supports form a V that opens upwards.
- supports have a mounting plate connected via a joint for the stops fixed to the building. An adjustment to different roof pitches is thus possible in a simple manner.
- the mounting plate will also be provided with holes for screwing.
- a rafter of the roof truss is provided with corresponding bores and screwing takes place, enclosing the mounting plate and the rafter.
- supports for the connection to the boom are designed as 3-point traverses, which have an attached round tube shaft with attached mounting plate at the other end.
- a simple and stable connection of the supports to the boom with the appropriate width dimensions is thus made possible.
- the connection of the mounting plate to the round tube shaft via a joint is just as easy as fixing it within the 3-point traverse.
- a turret can weigh a considerable amount, quite a few 100 kg.
- the scaffolding has a lifting device, for example a tripod, which is provided with a winch or preferably with a rigging plate and deflection rollers at its tip.
- lattice trusses are connected to the outer ends of the outriggers, in which the legs, for example tubes forming a tripod, are caught.
- This transition from one leg to a lattice truss also allows a comparatively simple but safe transition of the load from the tripod to the outriggers.
- a ring-shaped guide for a crane boom is provided on the traverses.
- a simple material transport is ensured by such a crane boom. Due to the ring-shaped guide, its orientation can be adapted to the respective building.

- the suspended scaffolding 1 shown in FIGS. 1 and 2 is used for work on a spire 2, for example replacing a turret ornament 3, here in the form of a cross.
- the suspended scaffolding 1 forms a working platform 4 that runs annularly around the top of the tower 3 .
- the work platform 4 is formed by 4-point trusses 5, which are provided with a walkable covering 6, for example made of wood.
- the covering 6 can protrude laterally from the traverses 5, so that the working width of the working platform 4 is increased, since the width of the traverses is typically between 40 cm and 60 cm.
- the working platform 4 is octagonal.
- Other geometries are of course possible.
- the octagonal shape has the advantage that straight trusses 10, 11 can be connected by commercially available 135° corner connectors 12, indicated in FIG.
- the straight trusses 10,13,14 are facing away from boom 15-17, connected at a right angle and the roof 18 of the spire 2.
- the free ends of the cantilevers 15-17 are under attack by the first supports 19-21.
- the first supports 19-21 are anchored to the building via indicated mounting plates 22, here on the roof truss of the top of the tower 2.
- connections of the boom 15-17 to the trusses 10,13,14 are of the second supports 23,24 under attack, the are set immediately adjacent to the first supports 19-21 on the roof truss of the spire 2.
- the support 25 has a 3-point traverse 26 with corresponding dimensions for the connection to the cantilevers 15-17 formed by 4-point traverses. At the other end, this merges into a central round tubular shaft 27, for example by welding. A mounting plate 29 with openings for screwing to the building is connected to this round tube shaft 27 via a joint 28 . In this respect, the support 25 can also be fastened with different roof pitches.
- conventional scaffolding anchors 35-37 are used to fix the suspended scaffolding 1.
- they extend opposite the outriggers 15-17 between the trusses 11,13,14 and the entablature of the top of the tower 2.
- the hanging scaffolding 1 has, for example, a lifting device 40 in the form of a tripod, shown only in FIG.
- the legs 42-44 of the lifting device 40 are supported on the outer ends of the outriggers 15-17.
- point lattice trusses are provided which pick up the dimensions of the outriggers 15-17 and in which the legs 42-44 of the hoist are caught, for example welded or fixed by clamps pipes.
- a rope of a cable-stayed cable car anchored to the floor is connected to the rigging plate 41, not shown in the drawing.
- a crane boom 45 is also provided for material transport, which can be displaced on an annular guide 46, see Fig. 2.
- the guide 46 is designed like a railing by a round tube 50 elevated above the covering 6 of the platform 4, see figure 4.
- Roller bearings 51 each with two rollers 52, 53, are movably mounted on the round tube 50.
- roller bearings 55,56; 59,60 are provided, the distance between which is defined by a profile 61 covering the guide, see Fig. 4.
- guy ropes 62,63 preferably adjustable in length, in order to be able to change the angle of the crane boom 45 relative to the horizontal.
