Description

The present invention relates to a modular scaffold tower or a stair scaffold module designed to construct a stair tower in a modular design.

From the DE 201 05 346 U1 is the structure of a z. B. in the field of a construction site usable stair tower with a variety of for providing a floor plan of the stair tower in a rectangular arrangement next to each other or in this arrangement one above the other positioned vertical stems known. In constructing such a stair tower, the vertical stems are connected to each other at different height positions by horizontal bars, for which purpose the horizontal bars are detachably connected to the vertical stems. Stair units are attached to horizontal bars connected at different elevations to the vertical stems, each having its lower staircase end portion and its upper stair unit end portion. In this case, the staircase units can be positioned in opposite directions, so that a zigzag-like arrangement with mutually laterally offset stair units is achieved. In an alternative construction option, the stair units can be positioned one above the other lying without lateral offset concurrently.

In such designed stair tower towers, the structure is successively from bottom to top. Accordingly, the reduction takes place successively from top to bottom. For suspended structures, such a suspended tower can be built from top to bottom and dismantled accordingly from bottom to top.

It is the object of the present invention to provide a modular scaffold tower, in particular for use on construction sites or the like, as well as a stair scaffold module for the construction of such a stair scaffold tower to provide, with which the construction and dismantling of a tower is simplified and faster with greater height.

• in jedem Moduleckbereich einen Vertikalstiel mit einem oberen Stielendbereich und einem unteren Stielendbereich,
• in den oberen Stielendbereichen der Vertikalstiele, eine obere Gruppe von damit lösbar verbundenen Horizontalriegeln,
• in den unteren Stielendbereichen der Vertikalstiele, eine untere Gruppe von damit lösbar verbundenen Horizontalriegeln,
• eine Treppeneinheit mit einem oberen Treppeneinheitendbereich und einem unteren Treppeneinheiteindbereich, wobei der obere Treppeneinheitendbereich mit einem Horizontalriegel der oberen Gruppe von Horizontalriegeln lösbar verbunden ist und der untere Treppeneinheitendbereich mit einem Horizontalriegel der unteren Gruppe von Horizontalriegeln lösbar verbunden ist.

According to a first aspect of the present invention, this object is achieved by a modularly constructed stair tower, comprising a plurality of stacked and detachable stair tower modules, wherein at least two, preferably all of the stacked stair tower modules include:

• in each module corner region, a vertical stem with an upper stem end region and a lower stem end region,
• in the upper stem end regions of the vertical stems, an upper group of horizontal bars releasably connected thereto,
• in the lower stem end regions of the vertical stems, a lower group of horizontal bars releasably connected thereto,
• a stair unit having an upper stair end portion and a lower step unit, the upper stair unit end portion being detachably connected to a horizontal latch of the upper group of horizontal bolts, and the lower stair unit end portion being detachably connected to a horizontal latch of the lower group of horizontal bolts.

In accordance with the principles of the present invention, a stair tower is constructed from a plurality of stackable stair tower modules. Each of these stair tower modules in turn is constructed with rod-like individual parts, ie in particular the vertical stems and the Horizontalriegeln, which form the basic structure in its entirety, where then additional components such. B. each a stair unit, are provided. This construction of a variety of rod-like items allows on the one hand due to the very compact stowage easy transport to the site, so for example a construction site, but on the other hand allows a high variability in the structure of the basic structure itself. Furthermore, there is the possibility of all necessary for building a stair tower tower stair frame modules individually on the ground standing together and then, for example, using a crane, the individually already assembled composite stair scaffold modules to each other and so build a modular stair tower tower. It goes without saying that the dismantling can be done in the reverse manner with the removal of the individual staircase modules from above and then the disassembly of the same on the ground.

In a particularly advantageous embodiment variant, it can be provided that, in the case of at least two immediately adjoining staircase frame modules, the staircase units are arranged offset laterally relative to each other. By the lateral offset of the stair units of two directly adjoining stair frame modules ensures that a walking the stair tower tower aggravating at least for larger persons space limitation on the individual stair units upwards practically does not occur. Only in every second stair scaffold module stair units run directly above each other and in the same direction, while in each case immediately adjacent stair scaffold modules, the stair units are laterally offset and positioned opposite to each other.

If the construction of a stair tower with each stacked stair units desired or required for structural reasons, it is further proposed that in association with at least one group of upper group of horizontal bars and lower group of horizontal bars provided a horizontal gear unit with a first horizontal gear unit end and a second horizontal gear unit end wherein the first horizontal gear unit end portion is releasably connected to a horizontal latch of the one group of horizontal bolts, and the second horizontal gear unit end portion is detachably connected to another horizontal latch of the one group of horizontal bolts. The horizontal bars of the two groups of horizontal bars, which are also provided for fixed connection of the stair units in the individual stair frame modules, can thus equally also be used to connect the horizontal gear units be used.

Advantageously, it is further provided that in at least two immediately superimposed stair tower modules, the stair units are arranged one above the other and that in association with the lower Treppeneinheitenendbereich the upper of the two stair frame modules and / or in association with the upper Treppeneinheitendbereich the lower of the two stair frame modules a horizontal gear unit is provided. This ensures that the path for walking on the stair tower tower is continued after a respective upper stair unit end area or lower stair unit end area by means of a horizontal gang unit in an immediately adjacent stair tower module.

In order to increase the surefootedness for the stair tower towering persons, it is further proposed that a distance between the upper or lower Treppeneinheitendbereich the stair unit of a stair frame module to a Horizontalgangeinheit or the lower or upper Stasseneinheitendbereich of the one stair frame module immediately adjacent another stair tower module essentially a stair unit Step height corresponds. The provided at a respective stair unit step height thus continues in the transition between a stair unit and a horizontal gear unit. The same applies if the path from one stair frame module to the other stair frame module is formed by adjoining end portions of two stair units.

• in jedem Moduleckbereich einen Vertikalstiel mit einem oberen Stielendbereich und einem unteren Stielendbereich,
• in den oberen Stielendbereichen der Vertikalstiele, eine obere Gruppe von damit lösbar verbundenen Horizontalriegeln,
  in den unteren Stielendbereichen der Vertikalstiele, eine untere Gruppe von damit lösbar verbundenen Horizontalriegeln,
• eine Treppeneinheit mit einem oberen Treppeneinheitendbereich und einem unteren Treppeneinheiteindbereich, wobei der obere Treppeneinheitendbereich mit einem Horizontalriegel der oberen Gruppe von Horizontalriegeln lösbar verbunden ist und der untere Treppeneinheitendbereich mit einem Horizontalriegel der unteren Gruppe von Horizontalriegeln lösbar verbunden ist,

wobei an den oberen Stielendbereichen und den unteren Stielendbereichen der Vertikalstiele Vertikalstielanbindungsorgane vorgesehen sind zur lösbaren Verbindung mit den Horizontalriegeln der oberen Gruppe von Horizontalriegeln und den Horizontalriegeln der unteren Gruppe von Horizontalriegeln.According to a further aspect, the object mentioned at the outset is achieved by a stair frame module, which can preferably be used in the modularly constructed stair tower described above, comprising:

• in each module corner region, a vertical stem with an upper stem end region and a lower stem end region,
• in the upper stem end regions of the vertical stems, an upper group of horizontal bars releasably connected thereto,
  in the lower stem end regions of the vertical stems, a lower group of horizontal bars releasably connected thereto,
• a stair unit having an upper stair end portion and a lower step unit, the upper stair unit end portion being detachably connected to a horizontal latch of the upper group of horizontal bolts, and the lower stair unit end portion being detachably connected to a horizontal latch of the lower group of horizontal bolts;

vertical stems connecting members are provided at the upper Stielendbereichen and the lower Stielendbereichen of the vertical stems for releasably connecting with the horizontal bars of the upper group of horizontal bars and the horizontal bars of the lower group of Horizontalriegeln.

Such a stair scaffold module is in itself a self-contained unit that can be stacked to build a stair tower in any, of course, the requirements of static stability expectant number to be stacked. Since in each such structural unit, the vertical stems and the one hand, the vertical stems connecting and on the other hand also used to connect a respective stair unit horizontal latch are releasably connected to each other, there is a high variability in construction and the possibility of space-saving transport and space-saving storage in the disassembled state.

In a staircase frame constructed according to the invention, it can be provided that the vertical stalk connecting elements provided at the upper end end regions of the vertical stems have a first distance to a respective upper vertical stalk end and the vertical stalk connecting elements provided at the lower end end regions of the vertical stems have a second distance to a respective lower vertical stalk end, wherein preferably the first distance substantially corresponds to the second distance. By providing a respective total distance the Vertikalstielanbindungsorgane to the vertical stem ends is taken to ensure that when positioning stair scaffold modules one above the other resulting from the sum of these two distances between a respective upper or lower Treppeneinheitendbereich a stair tower module to a respective assigned Treppeneinheitendbereich each immediately following stair frame module or possibly a Horizontalgangeinheit arises. It can thus be continued in the stair unit stepwise increase the way through a stair tower tower. Furthermore, a larger passage height can be achieved directly above one another, in particular when positioning concurrent staircase units.

To ensure a stepped scaffolding module or a step scaffolding tower constructed therefrom, it is further proposed that at least one distance of the horizontal bar of the upper group of horizontal bars to upper vertical bar ends and / or a distance of the upper bar detachably connected to an upper step unit end area and / or a horizontal table unit corresponding to a lower step unit end region and / or a Horizontalgangeinheit releasably connected horizontal bar of the lower group of horizontal bars to lower vertical stem ends substantially half of a stair unit step height.

Further, it is proposed for a stable and symmetrical design of a staircase scaffold module according to the invention that all horizontal bars of the upper group of horizontal bars are detachably connected to the vertical stakes in the same height position and / or that all horizontal bars of the lower group of horizontal bars with the vertical stakes in the same height position are detachably connected.

The Vertikalstielanbindungsorgane may for example comprise perforated discs or be constructed as such. Such perforated discs allow high variability in the connection of the vertical stems with horizontal bars. At the same time, this connection of the various rod-like components is easy and stable to manufacture and just as easy to pick up.

A particularly stable design with a comparatively small required area for constructing a stair tower with a plurality of stair scaffold modules can be ensured that the stair frame module is formed with quadrangular circumferential contour with a vertical stem in each of the four corner regions, wherein the upper group of horizontal bars on one side of the square peripheral contour comprises a horizontal bar for detachable connection with the upper stair unit end portion and the lower group of horizontal bars on one side of the square peripheral contour opposite other side of the quadrangular peripheral contour comprises a horizontal latch for releasable connection with the lower step unit end.

The stability of the individual stair tower modules can be further increased in that at least one, preferably both groups of upper group of Horizontalriegeln and lower group of horizontal bars in association with at least two opposite sides, preferably all sides of the quadrangular circumferential contour each with a two vertical stalks releasably connected horizontal latch include and / or that in association with at least two immediately adjacent vertical stems a with this and / or with a horizontal bar at least one group of upper group of horizontal bars and lower group of horizontal bars releasably connected diagonal bar is provided.

According to a further aspect, the present invention relates to a vertical handle, which can be used in a previously described Treppengerüstturm or stair scaffold module comprising a tubular stem body having a first Stielkörperendbereich and a second Stielkörperendbereich, wherein on the stem body a plurality of Vertikalstielanbindungsorganen, preferably perforated discs provided is, being one in the first Stielkörperendbereich provided Vertikalstielanbindungsorgan to a first stem end a first distance in the range of 5 to 20 cm, preferably about 10 cm, and provided in the second Stielkörperendbereich Vertikalstielanbindungsorgan to a second stem end a second distance in the range of 5 to 20 cm, preferably approximately 10 cm, has.

Such a vertical handle can therefore be used particularly advantageously, since the provided at the Stielkörperendbereichen Vertikalstielanbindungsorgane to the associated stem body ends such a distance that when positioning of different stair frame modules associated vertical stems one above the other provided in so formed adjoining areas between two stair frame modules Vertikalstielanbindungsorgane a total distance from one another have, which allows a particular continuation of a path through a so constructed stair tower with respect to a particular step height.

In a particularly advantageous development, it may be provided that the first distance and the second distance are substantially equal to one another, which means that the vertical stems are symmetrical to each other at least in their two Stielkörperendbereichen, preferably also to a longitudinal center of the respective stem body.

According to a further particularly advantageous aspect, provided on a respective stem body Vertikalstielanbindungsorgane on a substantially equal distance to each other, which on the one hand supports the symmetrical structure of the stem body with the Vertikalstielanbindungsorganen provided thereon, on the other hand also a uniform spacing of such connected to such Vertikalstielanbindungsorgane other components or Assemblies, such. B. Horizontal latch allows.

According to a further particularly advantageous aspect, the stem body may have a length in the range of 210 cm to 240 cm, preferably about 220 cm. This allows the construction of stair tower modules or stair tower towers or general scaffolding, in which superimposed modules or scaffolding sections have such a pitch or spacing that a comfortable walkability or even the requirements of the work to be done justice expects working height.

On a respective stem body can be provided four to six, preferably five, vertical stem connecting organs.

In order to be able to provide a stable connection of vertical stems to be positioned one above the other vertical stems, it is further proposed that on a Stielkörperendbereich of the first Stielkörperendbereich and second Stielkörperendbereich a projecting beyond the stem end of a Stielkörperendbereichs out coupling rod for insertion into the other Stielkörperendbereich the stalk body of another vertical stem is provided. In this case, the one end body end region can correspond, for example, to an upper end end region of a respective vertical stem, so that the coupling rods provided on such vertical stems project upwards and the positioning of further vertical stems can be effected from above by being pushed onto a respective coupling rod.

The present invention will be explained below in detail with reference to the accompanying drawings. It shows:

In Fig. 1 is a modular staircase tower, as it can be found, for example, in the field of construction sites for the construction of houses or the like, generally designated 10. In the example shown, the stair tower 10 comprises three stair frame modules M ₁ , M ₂ , M ₃ positioned one above the other. The three stair frame modules M ₁ , M ₂ , M ₃ are basically identical to each other and can be constructed for the construction of the stair tower 10 alone on the ground and are positioned on each other after completion. In this case, the lowermost stair scaffold module M _{1 is placed} on the scaffold feet 12 which can be supported on the ground and can be adjusted to compensate for unevennesses in the ground, for example by means of a screw-spindle connection. Above the uppermost stair frame module M ₃ , a railing unit 14 which is adapted in its circumferential contour to the rectangular peripheral contour and in the example shown is completely positioned, which secures people in the upper area of the stair tower 10 from falling.

In each of the stair frame modules M ₁ , M ₂ , M ₃ described in more detail below, a stair unit 16 is provided. The stair units 16 of the three stair frame modules M ₁ , M ₂ , M ₃ are positioned so that the stair units 16 are offset laterally with respect to each other in the staircase longitudinally positioned modules M ₁ , M ₂ , M ₃ , so that in each second superimposed positioned stair frame modules M ₁ , M ₂ , M _3, the stair units 16 are superimposed and run in the same direction, while in immediately adjacent stair tower modules M ₁ , M ₂ , M _3, the stair units 16 offset from each other and run against each other. This leads to a comparatively large vertical distance between directly superimposed stair units 16, so that such a stair tower 10 is comfortable to commit even for tall people.

Despite the necessary mutual displacement of staircase units 16 directly above one another positioned staircase scaffolding modules M _1, M _2, M ₃ and the opposing orientation of the staircase units 16 it is possible in such a structure of the stair scaffolding tower 16, identical to each other formed staircase scaffolding modules M _1, M _2, M ₃ to use, which are directly superimposed this stair frame modules M ₁ , M ₂ , M ₃ are rotated about a vertical axis by 180 ° with respect to each other.

An alternatively constructed stair tower 10 is in Fig. 2 shown. Here are components that have the same function or the same structure as in the stair tower 10 of Fig. 1 illustrated components, designated by the same reference numerals.

The at the stair tower 10 of the Fig. 2 used stair tower modules M ₁ , M ₂ , M ₃ correspond in their basic structure in Fig. 1 also shown stair frame modules M ₁ , M ₂ , M ₃ . The positioning of the staircase frame modules M ₁ , M ₂ , M ₃ in Fig. 2 However, it is such that the stair units 16 of all these stair frame modules M ₁ , M ₂ , M ₃ are superimposed without misalignment and arranged concurrently. This means that compared to Fig. 1 the middle of the three stair frame modules, so the stair tower module M ₂ , is rotated by 180 °.

In order to obtain in such a stair tower tower 10 from bottom to top continuous path, is provided at each of the stair tower modules M ₁ , M ₂ , M ₃ a generally designated 18 Horizontalgangeinheit. These Horizontalgangeinheiten 18 each connect an upper Stasseneinheitendbereich 20 a stair frame module with a lower stair unit end portion 22 of the immediately above the stair tower module. In the uppermost stair frame module M ₃ or the railing unit 14, the horizontal gearing unit 18 forms, for example, a working platform.

The construction of such a stair tower module is based on the in Fig. 3 Staircase module shown M ₁ described in detail below. It goes without saying that this structure can be implemented in a corresponding manner even in the case of the staircase frame modules M ₂ , M ₃ positioned above it, and both in the case of the stair tower tower 10 Fig. 2 , as well as the stair tower tower 10 of the Fig. 1 Application can be found.

This in Fig. 3 shown Staircase scaffolding module M ₁ has according to its rectangular peripheral contour in each of the four module corners 24, 26, 28, 30 in a constructed stair tower module M ₁ or in the stair tower tower 10 substantially vertically oriented extending vertical stem 32, 34, 36, 38. The vertical stems 32, 34, 36, 38 may, for example, each have an overall length of 210 cm to 240 cm, preferably about 220 cm. In example, regular distance from 40 cm to 60 cm, preferably about 50 cm, are on the vertical stems 32, 34, 36, 38 z. B. five Vertikalstielanbindungsorgane 40 z. B. provided in the form of so-called perforated discs 42. These are fixed to the generally tubular, so designed as a hollow rods vertical stems 32, 34, 36, 38, for example by welding. The vertical stems 32, 34, 36, 38 used in the four module corner areas 24, 26, 28, 30 are advantageously constructed identically to one another, such that vertical stems 32 constructed identically to one another in an entire stair tower tower are also provided in the respective module corner areas 24, 26, 28, 30 , 34, 36, 38 can be used.

The mutual connection of two z. B. in the module corner region 30 superposed vertical stems 38 is in Fig. 4 shown. For example, an upper stem end region 44 of the vertical stem 38 provided in the lowermost stair frame module M ₁ and, subsequently, a lower stem end region 46 of the vertical stem arm M ₁ on the stair frame module M _{1 can be seen here} positioned stair tower module M ₂ . The vertical stems 38 are each constructed with a tubular stem body 39. In this case, a first stem body end region 45 can respectively correspond to the upper stem end region 44 of a vertical stem 38, and a second stem body end region 47 can correspond to a respective lower stem end region 46 of a vertical stem 38. The in Fig. 4 vertically positioned upper stem 38 is with its lower vertical stem end 48, which may correspond to a stem end 49 at the second Stielkörperendbereich 47, on the upper vertical stem end 50, which may correspond to a stem end 51 at the first Stielkörperendbereich 45, the Staircase module M ₁ associated vertical stem 38. To avoid mutual slippage, the vertical stems 32, 34, 36, 38 may be constructed, for example, such that coupling rods projecting beyond the respective upper vertical stem ends 50 and first stem body ends 51 are provided in their upper stem end regions 44 and a respective first stem body end region 45 which can be inserted into the lower end of the stem 46 and second Stielkörperendbereich 47 of immediately above positioned vertical stems 38 and, for example, can be locked by locking pins therein.

One recognizes in the Fig. 3 and 4 in that the perforated disks 42 provided in the respective upper end end region 44 or first end body region 45 are arranged at a distance A _{1 from} the upper vertical stem end 50 and the first stem body end region 51, respectively. Likewise, the perforated disks 42 provided in the lower end end regions 46 and second end body end regions 37 are arranged at a distance A _{2 from} the respective lower vertical stem end 48 and second stem body end 49, respectively. It should be noted here that, of course, these distances A ₁ and A _{2 could} also be measured to the center of the respective perforated disc 42. As will be explained below, the two distances A ₁ and A _{2 are} preferably substantially identical to one another and, given a total length of the vertical stems 32, 34, 36, 38 of z. B. about 220 cm each in the range of z. B. are about 10 cm.

The vertical stems 32, 34, 36, 38 positioned in the four module corner areas 24, 26, 28, 30 are connected to each other by a plurality of groups of horizontal bars. In this case, a lower group G _U of horizontal bars comprises four horizontal bars 52, 54, 56, 58 detachably connected to the perforated discs 42 in the lower pedestal end regions 46. An upper group _G.sub.O of horizontal bars likewise comprises detachably connected to the perforated discs 42 in the upper pedicle end regions 44 Tied horizontal bars 60, 62, 64, 66. Between the lower group G _U and the upper group G _O can further, not designated by reference numerals groups of horizontal bars with in Zwischenlängenpositionen the vertical stems 32, 34, 36, 38 provided perforated discs 42 are connected to increase the stability of the stairwell modules while also providing a safety-enhancing railing around the perimeter of the stairwell modules.

As in Fig. 4 11, the horizontal bars, also illustrated generally as hollow bars, illustrated here with reference to the horizontal bars 66, 58, may have wedge heads 68 fork-likely engaging around their perforated discs 42 on which the unrecognizable holes in the perforated discs 42 are supported by wedges 70 that can be positioned throughout , By moving or pivoting the wedges 70, a stable connection between the Horizontalriegeln and the perforated discs 42 and thus also this carrying vertical stems 32, 34, 36, 38 are made.

To the stability of in Fig. 3 To further increase staircase scaffolding module M ₁ as shown, can at all four sides of the rectangular peripheral contour diagonal bar 72, 74, 76, are provided 78th For example, these can each be connected to a perforated disc 42 in the lower stem end region 46 of a vertical stem and to a perforated disc 42 in the upper stem end region 44 of an immediately adjacent vertical stem in a similar manner as in the case of horizontal bars. Also is It is possible, by means of fastening elements, to securely couple such diagonal bars 72, 74, 76, 78 to horizontal bars as an alternative or in addition to the connection to the vertical posts.

In the Fig. 3 Stair unit 16 identifiable in the stair frame module M ₁ comprises a staircase section 86 constructed, for example, with two beams 80, 82 and the steps 84 extending therebetween. Above, in upper staircase end region 20, an upper pedestal section 88 adjoins the stairway section 86. Below, in the lower staircase end region 22, a lower pedestal section 90 adjoins the stairway section 86. With the respective platform sections 88, 90 or provided thereon, not shown in the figures but hook-like connecting elements, the stair unit 16 can be detachably connected to the horizontal bar 62 of the upper group G _O of horizontal bars and equally releasably connected to the diametrically opposite side of the quadrangular Peripheral contour positioned horizontal bar 58 of the lower group G _{U are connected} by horizontal bars.

The coupling of the horizontal gear unit 18 likewise takes place in the same way. In the example shown, this has two horizontal gear plates 94, 96 positioned next to one another. In a first horizontal gear unit end portion 98 and a second horizontal gear unit end portion 100, these horizontal gear plates 94, 96 are detachably connected to horizontal hooks 54, 58 of the lower group G _U by horizontal hooks, for example with hook-type connecting members provided thereon with diametrically opposite sides of the quadrangular peripheral contour. This results in such an arrangement that the horizontal gear unit 18 is located at the same height and laterally next to the lower pedestal portion 90 of the stair unit 16. If the same height is used here, reference may be made, for example, to the surface of the horizontal gear unit 18 or the stair unit 16 in its lower pedestal section 90, which is positioned upwards and exposed for access.

When positioning several such stair module units M ₁ , M ₂ , M ₃ one above the other results in an overall arrangement in which, for example, in the in Fig. 2 recognizable structure of the vertical offset between an upper pedestal portion 88 of a stair unit 16 in a lower of two immediately adjacent stair frame modules to a horizontal gear unit 18 in the lower region of the upper of the two stair frame modules is approximately determined by the distances A ₁ and A ₂ of the horizontal bar of the two Groups G _U and Go of horizontal bars on the vertical stems 32, 34, 36, 38 coupling perforated discs 42 to the upper vertical stem end 50 and the lower vertical stem end 48. Advantageously, these two distances A ₁ and A ₂ are chosen so that they are approximately in sum Step height between two stages 84 of the staircase portion 86 correspond. This results in a corresponding spacing of the horizontal bars of the two groups G _U and G _O in the adjoining area of two stair frame modules M ₁ , M ₂ , M ₃ in a step height corresponding extent. This in turn results in that the upper pedestal portion 88 of the stair unit 16 of the stair tower module M _{1 has} a vertical distance corresponding to the step height to Horizontalgangeinheit 18 of the overlying stair scaffold module M ₂ , which may also be referred to the upwardly exposed to the surfaces of these again, for example two assemblies.

When committing the in Fig. 2 illustrated stair tower 10 is always where a step-like distance arises, so either between two immediately successive stages 84 or between the upper pedestal portion 88 and then the following horizontal gear unit 18 provided a uniform distance, resulting in a very high slip resistance. The same applies, of course, also for in the stair tower 10 of the Fig. 1 illustrated arrangement. There, in each case adjacent to an upper pedestal portion 88 lying lower pedestal portion 90 due to the relative height positioning of the two groups G _O and G _U of Horizontal latching to the step height in the respective stair sections 86 corresponding vertical distance thereto.

This horizontal spacing also ensures at the same time that at a standard height of the stair units between the upper pedestal section and the lower pedestal section of about 2 meters, adapted to the vertical spacing of the perforated discs 42 provided in the upper pedicle end regions 44 and the lower pedicle end regions 46, in the case of stacked staircase modules M ₁ , M ₂ , M _3, the height distance of directly superimposed stair units 16 in the in Fig. 2 shown overall structure with the same running stair units 16 is greater, namely increased by a distance which substantially corresponds to the sum of the two distances A ₁ and A ₂ .

It should be noted that in the stair tower 10 of the Fig. 1 Staircase modules shown M ₁ , M ₂ , M ₃ the in Fig. 3 may have structure described. Only the horizontal gear units 18 are in the in Fig. 1 illustrated structure not provided. To increase the security when walking the stair units 16 can there, as well as in the stair tower 10 of Fig. 2 existing stair units 16, along the respective stair section 86 extending and lateral falling down preventing handrails 102 and / or 104 may be provided.

With the structure described above, it is possible to build in a simple, but nevertheless more stable and variable in terms of design staircase modules that can then be stacked on their individual structure then, for example by means of a construction crane, thus generating a stair tower tower of any height. For the stair scaffold modules unified components can be used, due to the fact that virtually all components, such as vertical handles, horizontal bars, diagonal bars, stair units and Horizontalgangeinheiten, can be detached from each other in space-saving Store manner or can be transported to a site.

It should be noted that, of course, in the construction of such a stair tower module a variety of variations can be provided. Thus, not necessarily each group of horizontal bars must comprise four such horizontal bars. It is important in each case that the connection of the stair units or the Horizontalgangeinheiten on two diametrically opposite sides of the generally quadrangular or rectangular peripheral contour of the stair frame modules each have a horizontal bar in the lower region, ie in the lower group of horizontal bars, is provided and a Horizontal bar in the upper area, ie in the upper group of Horizontalriegeln provided. For stability reasons, it is of course advantageous to provide four horizontal bars for each or at least the upper and lower groups of horizontal bars. How the particular Fig. 3 However, this illustrated, does not have to be provided in association with each provided for the connection of horizontal bars perforated disc on the vertical stems actually such a group of horizontal bars.

Furthermore, in the case of the base structure constructed from vertical stems and horizontal bars and possibly diagonal bars, on which the stair units or horizontal gait units are carried, it may be provided that further vertical stems are provided in different sides of the circumferential contour in sections lying between module corner areas, depending on the required module size , so that, for example, modules with greater length and / or greater width can be built. Also, the vertical stems, for example, be shared and made of several, z. B. two, stem sections be composed.

It should also be noted that in a stair tower tower in Fig. 1 illustrated construction with opposite arrangement of immediately successive stair units and in Fig. 2 illustrated construction can be combined with superimposed and concurrently oriented stair units. It is also possible that in a stair tower with several of the above-described stair tower modules, other modules or construction sections with non-modular design can be provided or incorporated. For example, the above-described terrain unit after completion of a stair tower by stacking individual stair scaffolding modules on top of each other in the upper end, ie on the top stair frame module, be assembled on the tower itself and not necessarily also modular in construction initially assembled on the ground and then as a finished module on the top of the Staircase modules are positioned.

In the stair frame modules, the structure could be further such that the Horizontalgangeinheiten are each assigned to the upper Treppeneinheitend intended for such a module stair unit, so are connected to this lying at the same level at two horizontal bars of the upper group of horizontal bars. At the bottom of the then stacked stair tower modules could be provided, for example, in association with the upper Treppeneinheitendbereich and the lower Treppeneinheitendbereich a horizontal gear unit.

The vertical stems used for the construction of stair frame modules are advantageously constructed so that they are symmetrical to each other at least in their two Stielendbereichen or Stielkörperendbereichen to each other, ie, provided at the respective end perforated discs or possibly differently designed Vertikalstielanbindungsorgane point to the respective stem end or stem end an equal distance. Accordingly, also advantageously over the length of the vertical stems or their stem body distributed Vertikalstielanbindungsorgane each have a uniform spacing, so that the two stem ends or stem body ends of the vertical stems have a symmetrical, for example, with respect to a length center substantially symmetrical structure. Of course, a deviating from such a symmetrical configuration variant may be provided in which, for example, provided in the two Stielendbereichen or Stielkörperendbereichen Vertikalstielanbindungsorgane each associated stem end or stem body end have a different distance, but advantageously the distance of such a Vertikalstielanbindungsorgans to the associated stem end or stem end should not exceed a predetermined maximum dimension of, for example, 20 cm.
