WAYS OF CARRYING OUT THE INVENTION

1 to 3 is a first embodiment of a shell stair tower 10.1 shown schematically. The Shell stair tower 10.1 essentially has scaffolding standard components based on the well-known Layher all-round scaffolding system come. The shell stair tower has 10.1 a rectangular plan. In the corner points are stacked vertical stems 12 arranged in Grid sizes from 1 to 4 m (meters) in 50 cm increments (Centimeter increments) are available. In Longitudinal direction of the vertical stems 12 are in a grid dimension R on each vertical stem 12 with surrounding rosettes 14 Recesses exist on which further scaffolding components can be connected. The rosettes 14 are in the Longitudinal grid dimension R available, that in the exemplary embodiment each is 50 cm (centimeters). Transversely, that means perpendicular to the representation in Figure 1, are each two crossbars 16 connected to rosettes 14, which as U-profiles open at the top are formed. On the two Side edges are at the level of the crossbars 16 longitudinal bars 18th connected, which are designed as round tubes. Of Furthermore, diagonals 20 are connected, on the one hand serve for stiffening and on the other hand in the existing Shell stair tower implement a handrail function.

The connection of the cross bar 16, longitudinal bar 18 and Diagonals 20 take place over the known as such Wedge lock technology and is for example in the Publication "Installation instructions for the Layher all-round scaffolding" described in detail. The bars 16, 18 and Diagonals 20 each have a wedge head in their end region Gap that can be pushed onto the rosette 14, the component itself by driving in a wedge is releasably locked to the vertical handle.

The components mentioned form a self-contained system. In addition to the standard scaffolding parts mentioned Stair devices 30 are present, which are shown in FIGS and 18 are described in more detail.

The shell stair tower 10.1 is in a stair hole 46 the dimensions B1 and B2 of a shell building 48 arranged, the Floor slabs 49.1, 49.2. The floor height G is indicated by the reference symbol G.

In practice, the system vertical dimensions of the Vertical sticks 12 in 50 cm increments (centimeter increments) are designed. These are usually with the Storey heights G, for example approx. 270 cm (centimeters) amount, not compatible. Through the special training the staircase devices 30, however, becomes one here Compatibility created. The height difference of each Steps of the staircase devices 30 correspond to that half pitch R.

Such a staircase device is shown in FIGS. 17 and 18 30 shown in more detail. The staircase device 30 is designed as a framework. She owns her Side edge areas two inclined support profiles 56, those in the upper or lower end area horizontally are formed, on these horizontal areas exit level 44 or entry level 42 is arranged. Between entry level 42 and Exit step 44 are on triangular bracket beams 58 Treads 32 stored.

The height distance R / 2 between steps 42, 32, 44 is half of the longitudinal grid dimension R. Im The front end area is in each case transverse to the support profiles 56 Cross section 60 connected. Located on the cross section 60 each in the left or right edge area a claw unit 28, which in the upwardly open U-profile a cross bar 16 can be hung. Overall points the stairway device 30 has a width B which is so is formed that on a crossbar 16 at a opposite stairs two and in the same direction Stairs can be hung up a staircase means here that the system dimensions of the Standard cross bar 16.

The one inclined to the left in FIG. 1 lowest first and third staircase is in the area her entry level 42 into one on a rosette 14 connected crossbar 16 hooked. In the field of Exit stage 44 (area A in FIG. 1) is the Stair device 30 connected to a cross bar, the between two standard rosettes 14 each via a releasably clampable to the vertical handle 12 connectable rosette 15 connected. This as such Known releasably clampable rosette 15 consists essentially made of two half-ring-shaped rosette elements, which with the Vertical handle 12 are jammed. Is in the same area facing outward, a console unit 50 with a triangular bracket 52 and one thereon arranged console covering 54 available, the Inspection area enlarged in this area. The in Figure 2 second and fourth stair device 30 inclined to the right is also suspended in crossbar 16 in area A. and in the area of its exit step 44 to a cross bar 16 connected, which in turn is connected to a standard rosette 14 connected. There is also an after in this area outside console unit 50 arranged. The Entry level 42, exit level 44 and the Console unit 50 are located at a height that the Floor height G of the first floor corresponds to 49.1.

The second floor 49.2 is basically the same connected another two oppositely arranged Stair facilities 30 reached, due to the given system dimensions, the upper exit step 44 and Console unit 50 one step lower than that Floor height G of the second floor 49.2 is arranged.

In addition, in the middle of the construction stair tower is from above running continuously downwards between the opposing ones Stair devices 30 connected to a vertical rod 34, which serves as a hand support and further increases safety on foot elevated. This vertical rod 34 can in the whole Inspection process to be taken, so that an inside Manual guidance as for a spiral staircase.

Seen in a top view, emerges between two oppositely arranged stair devices 30 due to the existing system dimensions a gap, which in particular in Area of exit steps 44 arranged side by side or entry levels 42 perceived as disturbing becomes. A cover profile rod 36 is therefore used in this area connected, the schematic in Figure 15a and b is shown.

This cover profile rod 36 consists of an in the embodiment formed as a rectangular tube, the one Width BS has the width of the between inclusion Exit stage 42, 44 existing gap in the Essentially corresponds. In its outside end area the cover profile rod has a U-profile unit pointing downwards 38, which has such a large internal dimension has that over the U-profile of the transom 16 can be hung. In the other end area of the cover profile rod a pipe half coupling 40 is connected so that the profile rod 36 easily to the vertical rod 34 is attachable.

A second exemplary embodiment is shown in FIGS of a shell stair tower 10.2 described one basically has the same structure as the Shell stair tower 10.1 according to Figures 1 to 3. Same Components have the same reference number and are not explained again. However, it is the case here that the Installation situation not the use of console units allows, because the stair hole 46 a reduced dimension B1 having.
