WAYS FOR CARRYING OUT THE INVENTION

In the FIGS. 1 to 3 is a first embodiment of a shell construction tower 10.1 shown schematically. The shell construction tower 10.1 essentially comprises stand standard components which originate from the known Layher Allround scaffolding system. The Rohbautreppenturm 10.1 has a rectangular plan. In the corner points stacked vertical stems 12 are arranged, which are available in grid dimensions of 1 to 4 m (meters) in 50 cm increments (centimeter increments). In the longitudinal direction of the vertical stems 12 circumferential rosettes 14 are provided with recesses in a grid R on each vertical stem 12, where more scaffolding components can be connected. The rosettes 14 are present in the Längsrastermaß R, which is in the embodiment, each 50 cm (centimeters). In the transverse direction, that is perpendicular to the representation in FIG. 1 , are each two cross bar 16 connected to rosettes 14, which are formed as upwardly open U-profiles. At the two side edges 16 longitudinal latch 18 are connected at the height of the crossbar, which are formed as round tubes. Furthermore, diagonal 20 are connected, on the one hand serve to stiffen and on the other hand implement a handrail function in existing Rohbautreppenturm.

The connection of the cross bar 16, longitudinal bar 18 and diagonal 20 via the known as such Keilschlosstechnik and is described in detail, for example, in the publication "Installation Note for the Layher Allround Scaffold". In this case, the bars 16, 18 and diagonals 20 in their end region in each case a wedge head with gap, which can be pushed onto the rosette 14, wherein the component itself is releasably locked by striking a wedge on the vertical stem.

The components mentioned form a self-supporting system. In addition to the standard framework parts mentioned, staircase devices 30 are present, which are described in more detail with reference to FIGS. 17 and 18.

The shell construction tower 10.1 is arranged in a stairway hole 46 with the dimensions B1 and B2 of a shell building 48, which has projectile ceilings 49.1, 49.2. The floor height G is indicated by the reference symbol G.

In practice, the system vertical dimensions of the vertical stems 12 are designed in increments of 50 cm (centimeter increments). These are usually not compatible with the storey heights G, which are for example about 270 cm (centimeters). Due to the special design of the stair means 30 but here is a Compatibility generated. The height difference of the individual treads of the stair means 30 correspond to half the grid R.

In Figures 17 and 18, such a stairway device 30 is shown in more detail. The staircase device 30 is designed as a frame structure. It has at its side edge regions two inclined support profiles 56 which are formed horizontally in the upper and lower end region, wherein on these horizontal areas the outlet stage 44 and inlet step 42 is arranged. Between entry step 42 and exit step 44, step treads 32 are supported on triangular brackets 58.

The height-wise distance R / 2 between the steps 42, 32, 44 is in each case half of the longitudinal raster dimension R. In the front end region, a transverse profile 60 is connected in each case transversely to the support profiles 56. On the transverse profile 60 is located in each case in the left or right edge region a claw unit 28 which can be suspended in the upwardly open U-profile of a cross bar 16. Overall, the stairway device 30 has a width B which is formed so that a staircase can be hung on a cross bar 16 in a counter-rotating staircase two and a co-flight staircase, that is, here is a vote on the system dimensions of the standard cross bar 16th

Like from the FIGS. 1 to 3 it can be seen, there the stair means 30 are arranged in opposite directions. To bridge the floor height G two stairway devices 30 are available. In the FIG. 1 The lower left first and third staircase is in the area her entrance step 42 mounted in a connected to a rosette 14 crossbar 16. In the area of the outflow stage 44 (area A in FIG FIG. 1 ), the stairway device 30 is connected to a crossbar, which is connected between two standard existing rosettes 14 each via a releasably clamped to the vertical stem 12 connectable rosette 15. This known as such releasably clampable rosette 15 consists essentially of two semi-annular rosette elements that are jammed with the vertical stem 12. In the same area, a console unit 50 with a triangular console support 52 and a console covering 54 arranged thereon is present outwardly, which enlarges the access area in this area. In the FIG. 2 second and fourth staircase inclined to the right 30 device is also suspended in the area A in the cross bar 16 and connected in the region of its exit stage 44 to a cross bar 16, which in turn is connected to a standard rosette 14. Also in this area an outwardly projecting console unit 50 is arranged. The entry step 42, the exit step 44 and the console unit 50 are located at a height corresponding to the storey height G of the first projectile 49.1.

The second projectile 49.2 is reached by another equal two connected counter-stair equipment 30 in principle, due to the predetermined system dimensions, the upper exit stage 44 and console unit 50 is disposed lower by a tread height than the floor height G of the second projectile 49.2.

In addition, in the middle of the construction stair tower from top to bottom running continuously between the opposing Stairways 30 a vertical rod 34 connected, which serves as a hand support and further increases the occupancy. This vertical rod 34 can be taken in the entire Begehungsvorgang so that adjusts an inside hand guide as in a spiral staircase.

Seen in a plan view, a gap arises between two counter-running stair devices 30 due to the existing system dimensions, which is felt to be disturbing, in particular in the region of side-by-side exit steps 44 or entry steps 42. Therefore, a cover profile bar 36 is connected in this area, the in FIGS. 15a and b is shown schematically.

This Abdeckprofilstab 36 consists of a trained in the embodiment as a rectangular tube profile bar having a width BS, which corresponds to the width of the Einbeziehungsweise exit step 42, 44 existing gap substantially. In its outside end region, the cover profile bar has a downwardly pointing U-profile unit 38, which has such a large, light internal dimension that it can be hooked over the U-profile of the transverse bar 16. In the other end of the Abdeckprofilstabs a pipe half-coupling 40 is connected, so that the profile bar 36 is easily attachable to the vertical rod 34.

In the FIGS. 4 to 6 a second embodiment of a shell construction tower 10.2 is described, which has a basically the same structure as the shell construction tower 10.1 according to the FIGS. 1 to 3 , The same components bear the same reference numerals and will not be explained again. However, it is here that the Installation situation does not allow the use of console units, since the stairwell 46 has a reduced dimension B1.

The first, lowermost stair device 30 is connected to a cross bar, which in turn is connected via an offset by the grid R / 2 to the standard rosette 14 clamped rosette. In the area of the entrance step 42, this stairway device 30 is connected to a transverse bar 16, which is connected to a grid standard existing rosette 14. Offset in the transverse direction, the next stairway device 30 is connected in the region of its entry step 42 to the same transverse bar 16. The exit step 44 of this staircase 30 is in turn connected to a crossbar 16, which in turn is connected to a detachably connected between two standard rosettes 14 rosette. Thus, the exit step 44 of the second stairway device 30 is at the height of the first projectile 49.1. The connected at this level third stair device 30 is in turn connected in the region of its exit stage 44 to a crossbar 16, which in turn is connected to standard rosettes 14. The fourth stairway device 30 is offset in its entry area to the grid R / 2 offset to a crossbar 16, which in turn is connected between the grid dimensions in the middle between the grid of the standard rosettes 14 arranged detachable rosette. Thus, the area of the exit step 44 of the fourth stairway device 30 is at the level of the second floor 49.2 and can thus be shot against a cross bar 16, which in turn is itself connected via standard rosettes 14.

In the FIGS. 7 to 9 is a third embodiment of a shell construction tower 10.3 shown, which is designed as a concurrent stairs. The components already described are used. The same components bear the same reference numerals and will not be explained again. In contrast to the counter-rotating stair devices 30 described above, the shell construction tower 10.3 is composed of two series-connected "framework fields", with a total of six scaffolding posts 12 being used. The stairway devices 30 themselves are arranged one behind the other, so that one floor height G is bridged with two stairway devices 30.

The first lower staircase device is connected to a crossbar 16, which in turn is offset by the grid R / 2 to standard rosette 14 is present. In the area of the exit step 44, the lower staircase device 30 is connected to a transverse bar 16, which is connected by default to a standard rosette 14 of the grid R type. At the same cross bar 16, the area of the entrance step 42 of the second concurrent stair devices 30 is connected, the exit step area is in turn connected to a cross bar 16 which is offset in the grid by R / 2 against a standard rosette 14 to the vertical stem 12 via the detachable rosette 15 is connected , Thus, the exit step 44 of the second staircase device is at the level of the first projectile 49.1.

The third stairway device 30 is in turn connected to a transverse bar 16, which is connected to a standard rosette 14 in the region of its inlet step 42, in which case there is already a grid-like offset in the size of R / 2 to the storey height G of the first projectile 49.1.

The exit region of the third stairway device 30 is in turn connected to a transverse bar 16, which is connected to the grid R / 2 offset to a detachably connected to the vertical stem 12 rosette 15 is connected. At the same cross member 16, finally, the fourth concurrent stair device 30 is connected in the region of its inlet step 42, which in turn is connected in the region of its exit stage 44 on the upper side to a transverse bar 16 which is connected to a standard rosette 14, in which case the exit step 44 on the floor level G of the second floor 49.2 is located.

In the FIGS. 10 to 12 is a fourth embodiment of a shell construction tower 10.4 shown, which is similar to the shell construction tower 10.2 of its basic structure, but in which the use of detachably connected between the standard rosettes 14 rosettes is omitted and for a specially trained crossbar 24 is used in FIG. 16 is shown. The crossbar 24 according to FIG. 16 However, on the underside two suspension sections 64, a beam 26 is connected, which is formed as an upwardly open U-profile corresponding to the cross section of the cross bar 16 on the lower side is. In this case, the beam 26 is offset by the grid R / 2 down to the upper cross bar profile available. The width BU of the beam 26 is dimensioned slightly larger than the width B of a stairway device 30, so that it can be hooked easily on their Einhängekrallen 28 in the beam 26. Again, a vertical rod 34 is connected centrally on the outside, which increases especially when entering and exiting through the additional holding possibility Begehicherheit.

With this cross bar 24 is now the fourth embodiment of the shell construction tower 10.4 according to the FIGS. 10 to 12 educated. The lowermost stair device 30 is connected in the region of its entry step 42 to a standard cross bar 16. The region of its exit step 44 is suspended in the lower beam 26 of the cross bar 24. The adjoining second stairway device 30 is in turn hooked in the upper profile of the cross bar 24 in its region of the entry step 42. The region of the exit step 44 of the second stairway device 30 is in turn suspended in the lower run 26 of a transverse bar 24. Accordingly, the arrangement of the third and fourth stair means 30.

With the Rohbautreppenturm invention using a variety of standard scaffolding components is possible to economically use only using less additional components self-supporting Rohbautreppentürme that easily compensate for the different grid dimensions of the scaffolding and the storey heights, and are adaptable to the existing staircase hole dimensions of the shell.
