Description

DESCRIPTION

Ladder scaffold module

The present invention relates to a ladder scaffold module according to the preamble of claim 1.

A ladder scaffold module according to the preamble of claim 1 is known from the "PERI PD 8 Stair Tower" standard design assembly and use instructions, edition 04/2008.

From DE 201 05 346 U1 the structure of a ladder scaffold tower can be used, for example in the area of a construction site, with a plurality of vertical struts placed side by side in a rectangular arrangement or one on top from others in this arrangement to provide a stair scaffold tower plan. In the construction of such a stair tower, the vertical struts are connected to each other at different height positions by means of horizontal pins, for which the horizontal pins are removably coupled to the vertical struts. The stair units are fixed to the horizontal beams connected to the vertical struts at different height positions respectively with their stair unit lower end and their stair unit upper end. Stair units can be positioned in opposite directions, so that a zigzag arrangement is achieved with stair units offset laterally alternately with respect to each other. In an alternative mounting possibility, the ladder units can be placed on top of each other without lateral movement in the same direction.

In stair towers of this type, the assembly is carried out successively from the bottom up. Consequently, dismantling is also carried out successively from top to bottom. In the case of suspended structures, a tower suspended in this way can be assembled from top to bottom and consequently disassembled from bottom to top.

Another ladder scaffold module is known from JP H08-199799 A.

The task of the present invention is to provide a ladder scaffold module for the assembly of a ladder scaffold tower of modular construction, especially for use in construction sites or the like, with which the assembly and disassembly of a tower , which meets the requirements of static stability, can be carried out more easily and quickly, even at a higher height.

This task is solved with a ladder scaffold module according to claim 1 which can be used in a ladder scaffold tower of modular construction. This ladder scaffold module comprises:

- in each module corner zone, a vertical prop with an upper prop end zone and a lower prop end zone,

- in the upper end zones of the vertical struts, an upper group of horizontal pins removably connected to them,

- in the lower end zones of the vertical struts, a lower group of horizontal pins removably connected to them,

- a stair unit with an upper stair unit end zone and a lower stair unit end area, the upper stair unit end area being removably attached with a horizontal pin to the upper horizontal group of pins and the zone of lower ladder unit with a horizontal pin to the lower horizontal pin group,

providing in the upper strut end areas and in the lower strut end areas of the vertical struts connection elements of vertical struts in the form of perforated discs connection for detachable connection with the horizontal pins of the upper horizontal pin group and the horizontal pins lower horizontal pin group.

A ladder scaffold module represents in itself a complete building unit that can be stacked in any desired number for the construction of a ladder scaffold tower, logically meeting the static stability requirements. Since in each of these building units the vertical struts and horizontal pins, which on the one hand connect the vertical struts and on the other hand also serve to connect a respective ladder unit, are removably connected to each other, there is a high degree of variability in assembly and the possibility of space-saving transport and storage in the disassembled state.

For a stable and symmetrical embodiment of a ladder scaffold module constructed according to the invention, it is envisaged that all the horizontal pins of the upper horizontal group of pins are detachably connected to the vertical struts in the same height position and that all The horizontal pins of the group of horizontal pins are removably connected to the vertical struts in the same height position.

A particularly stable embodiment with a comparatively small footprint for mounting a ladder scaffold tower with a plurality of ladder scaffold tower modules is ensured by configuring the ladder scaffold tower module with a square perimeter contour with a vertical strut in each of the four corner areas of the module, comprising the upper group of horizontal pins by one of the sides of the square perimeter contour a horizontal pin for the removable connection to the end zone of the upper stair unit, and the group of horizontal pins on the other side of the square perimeter contour opposite said side of the square perimeter contour a horizontal pin for the connection removable to the end area of the lower stair unit.

The stability of the various ladder scaffolding modules itself is enhanced by the fact that the two groups formed by the upper horizontal pin group as well as the lower horizontal pin group comprise, in their assignment, all the sides of the square perimeter contour respectively a pin removably coupled to two of the vertical struts provided in the four corner areas of the modules.

In a ladder scaffold module constructed according to the invention, it is further provided that the coupling elements of the vertical strut arranged in the end regions of the vertical struts have a first distance from the upper end of the vertical strut and that the coupling elements of the vertical strut arranged in the end zones of the vertical struts have a second distance with respect to the lower end of the vertical strut, the first distance corresponding primarily to the second distance. By providing a total distance of the connection elements of the vertical strut with respect to the strut ends, it is ensured that, when positioning the ladder scaffold modules one above the other, a distance generated by the summation is also produced. of these two distances, between the respective upper or lower ladder unit end zone of a ladder scaffold module and a ladder unit end zone with respect to a directly adjacent ladder scaffold module or, where appropriate, a horizontal aisle unit. Therefore, the stepped elevation of the path provided in the ladder unit can be continued by means of a ladder scaffold tower. In addition, a higher step height can be achieved, particularly when the stair units directly overlap in the same direction.

In order to ensure a step height that continues uniformly in a ladder scaffold tower module and / or a ladder scaffold tower constructed therewith, it is further proposed that at least a distance from the removably attached horizontal pins to the end zone of the upper ladder unit and / or of a horizontal corridor unit of the upper group of horizontal pins relative to the ends of upper vertical struts and / or a distance from the horizontal pins removably attached to the end zone of lower ladder units of the lower group of horizontal pins relative to the ends of vertical struts corresponds essentially to half a step height of the ladder unit.

Since the connecting elements of the vertical strut are configured in the form of perforated discs, a high variability is achieved in the connection between the vertical struts to the horizontal pins. At the same time, this connection of the various rod-shaped components can be easily and stably established and just as easily undone.

Furthermore, in assignment to at least two directly adjacent vertical struts, a diagonal pin is provided which is removably coupled thereto.

A vertical strut, which can be used in a ladder scaffold module described above, may comprise a tubular strut body with a first strut body end region and a second strut body end region, it being possible to provide on the strut body strut a plurality of vertical strut connecting elements in the form of perforated discs, a vertical strut connecting element provided in the end region of the first strut body having a first distance in the range of 5 to 20 cm, preferably about 10 cm, relative to a first strut body end and a vertical strut connection element provided in the end region of the body of the second strut body end a second distance in the range of 5 to 20 cm, preferably about 10 cm , relative to a second end of the strut body.

A vertical strut such as this can therefore be used particularly advantageously, since the vertical strut connecting elements provided in the respective strut body end regions have a distance from the assigned strut body ends which, If the vertical profiles assigned to different ladder scaffolding modules are positioned on top of each other, the vertical strut connection elements provided in the limitation zones thus created between two ladder scaffold modules have a total distance from each other which allows a constant continuation of a path through a ladder scaffold tower constructed in this way, especially also with regard to the height of the steps.

In a particularly advantageous improved embodiment, provision can be made for the first and second spacing to be substantially equal to each other, which means that at least in their two end regions of the strut body the vertical struts are configured symmetrically with each other, preferably also with respect to a longitudinal center of the respective strut body.

According to a further particularly advantageous aspect, the vertical strut connecting elements provided on the respective vertical strut have a substantially equal distance, which, on the one hand, promotes the symmetrical structure of the strut body with the strut connecting elements provided therein allowing, and on the other hand, that the other components or construction groups coupled to these vertical strut connection elements, for example horizontal pins, also have a uniform distance.

According to another particularly advantageous aspect, the strut body can have a length in the range from 210 cm to 240 cm, preferably about 220 cm. This allows the mounting of ladder scaffold modules or ladder scaffold towers or scaffolding in general, in which the modules or scaffold sections placed one on top of the other have a distance or separation such that there is a comfortable accessibility or also a working height that meets the requirements formulated for the work to be performed.

Four to six, preferably five, vertical strut connecting elements can be provided on a respective strut body.

In order to be able to provide a stable connection of vertical struts superimposed in the vertical direction, it is further proposed that in an end zone of the first and second end zone of the strut body a coupling rod is arranged protruding from the end of the strut body of a of the strut body end zones for insertion into the other strut body end zone of the other vertical strut. The end zone of the strut body may correspond, for example, to an end zone of the upper strut of the respective vertical strut, so that the coupling bars provided on these vertical struts protrude upwards, the positioning of other vertical struts being able to be carried out from upwards by sliding them on the respective coupling bar.

The present invention also relates to a ladder scaffold tower of modular construction comprising a plurality of the above-described ladder scaffold tower modules superimposed and removable from one another.

A ladder scaffold tower is constructed from a plurality of ladder scaffold tower modules that can be placed on top of each other. Each of these ladder scaffolding modules is in turn composed of individual rod-shaped components, i.e. especially vertical struts and horizontal pins, which in their entirety form the basic structure on which further subsets are provided, for example, respectively a stair unit. On the one hand, this structure of a plurality of individual pieces in the form of a rod allows, thanks to the possibility of compact placement, easy transport to the place of use, for example to a construction site, but on the other hand it also allows great variability in the assembly of the basic structure itself. There is also the possibility of assembling all the ladder scaffolding modules required for the construction of a ladder scaffolding tower individually on the ground and to place the already assembled ladder scaffolding modules subsequently, for example by means of a crane, place the various assembled ladder scaffolding modules on top of each other to build a modular ladder scaffold tower. Obviously, disassembly can be done in reverse by removing the individual ladder scaffolding modules from above and then disassembling them on the ground.

In a particularly advantageous embodiment variant, provision can be made for the ladder units to be arranged laterally offset from one another in the case of at least two directly adjacent ladder scaffolding modules. By laterally shifting the ladder units from two adjacent ladder scaffold modules, it is ensured that there is practically no space restriction above the individual ladder units upwards that could make access to the ladder scaffold tower difficult. , at least for people of greater stature. Only in one out of every two ladder scaffold modules do the ladder units run directly above each other and in the same direction, while in the case of directly adjacent ladder scaffold modules the ladder units are positioned laterally displaced and in the opposite direction.

If for structural reasons the construction of a ladder scaffold tower with respectively superimposed ladder units is desired or required, it is further proposed that, in assignment to at least one of the groups of the upper horizontal group of pins and of the group of pins horizontal aisle unit, a horizontal aisle unit is arranged with a first horizontal aisle unit end zone and a second horizontal aisle unit end zone, the first horizontal aisle unit end zone being removably coupled to a horizontal pin of one from the horizontal pin groups and the second horizontal aisle unit end zone removably to another horizontal pin from the horizontal pin group. Consequently, the horizontal pins of the two groups of horizontal pins, also provided for the fixed connection of the ladder units in the different ladder scaffolding modules, can be used interchangeably for the connection of the horizontal corridor units.

Advantageously, it is further provided that, in the case of at least two directly superimposed ladder scaffolding modules, the ladder units are arranged one above the other and that, in assignment to the bottom ladder unit end zone of the upper module of the two ladder scaffold modules and / or in assignment to the upper ladder unit end zone of the lower module of the two ladder scaffold modules a horizontal corridor unit is arranged. This ensures that, downstream from the respective upper ladder unit end zone or the lower ladder unit end zone, the horizontal corridor unit constitutes a continuation of the accessible path of the ladder scaffold tower in the respective directly adjacent ladder scaffold module.

In order to increase the tread safety of people accessing the ladder scaffold tower it is further proposed that a distance between the upper or lower ladder unit end zone of a ladder scaffold module and a horizontal corridor unit or the end zone of the lower or upper stair unit of another module of ladder scaffold immediately adjacent to a ladder tower module is substantially equal to the step height of the ladder unit. Therefore, the step height provided in the respective stair unit has its continuation in the transition zone between a stair unit and a horizontal corridor unit. The same is true if the path from one ladder scaffold module to another ladder scaffold module is formed by adjacent end zones of two ladder units.

The present invention is explained in detail below with reference to the accompanying figures. It is shown in:

FIG. 1 is a perspective representation in principle of a ladder scaffold tower of modular construction;

FIG. 2 a representation corresponding to FIG. 1 of a ladder scaffold tower of alternative construction;

Figure 3 a ladder scaffold module for the ladder scaffold tower shown in figure 2;

Figure 4 in an enlarged representation, the adjacent area of two vertical struts of superimposed ladder scaffolding modules.

In Figure 1, a ladder scaffold tower of modular construction, such as those that may be used in the field of house construction sites or the like, is generally identified by the number 10. The ladder scaffold tower 10 comprises in the illustrated example three ladder scaffolding modules M1, M2, M3 placed one on top of the other. The three ladder scaffold modules M1, M2, M3 are basically identical in construction and each of them can be self-mounted on the ground for 10 ladder scaffold tower construction and placed after completion on top of other. The lowest ladder scaffold module M1 is placed on scaffold legs 12, which can be supported on the ground and adjusted, for example by means of a threaded spindle connection, in order to compensate for uneven ground. On the highest ladder scaffold module M3 a railing unit 14 is placed, the perimeter contour of which conforms to the rectangular perimeter contour and which, in the example shown, completely surrounds the ladder scaffold tower, preventing a fall of the stairs. people standing on top of ladder scaffold tower 10.

In each of the ladder scaffold modules M1, M2, M3 which will be described in more detail later on, a ladder unit 16 is provided. The ladder units 16 of the three ladder scaffold modules M1, M2, M3 are positioned so that in the directly superimposed ladder scaffold modules M1, M2, M3 the ladder units 16 are offset laterally with respect to the longitudinal direction of the ladder, so that in one out of every two ladder scaffold modules M1, M2, M3 superimposed the ladder units 16 are on top of each other and in the same direction, while in the directly adjacent ladder scaffold modules M1, M2, M3 the ladder units 16 are offset relative to each other. others and develop in opposite directions. This results in a comparatively large height distance between the directly overlapping stair units 16, so that such a stair scaffold tower 10 can be comfortably stepped on even by tall persons.

Despite the necessary mutual displacement of the ladder units 16 of the directly superimposed ladder scaffold modules M1, M2, M3 and the opposite orientation of the ladder units 16 results in a structure like this of the ladder scaffold tower 16 It is possible to use ladder scaffold modules M1, M2, M3 identical to each other, turning the ladder scaffold modules M1, M2, M3 directly superimposed by 180 ° relative to each other around a vertical axis.

An alternately mounted ladder scaffold tower 10 is depicted in Figure 2. Here, components that have the same function or structure as the components shown on the ladder scaffold tower 10 of Figure 1 are identified by the same numbers. reference.

The ladder scaffold modules M1, M2, M3 used in the ladder scaffold tower 10 of figure 2 correspond in their basic structure to the ladder scaffold modules M1, M2, M3 also illustrated in figure 1. However , the positioning of the ladder scaffold modules M1, M2, M3 in figure 2 is such that the ladder units 16 of all these ladder scaffold modules M1, M2, M3 are located one above the other without displacement and in the same direction. This means that, compared to Figure 1, the central module of the three ladder scaffold modules, that is, the M2 ladder scaffold module, has been rotated by 180 °.

In order to achieve a continuous path from bottom to top in such a ladder scaffold tower 10 also, a horizontal corridor unit generally designated with the number 18 is provided in each of the ladder scaffold modules M1, M2, M3. These horizontal corridor units 18 respectively connect an upper ladder unit end zone 20 of a ladder scaffold module with a lower ladder unit end zone 22 of the immediately higher ladder scaffold module. In the case of the upper ladder scaffold module M3 or the railing unit 14, the horizontal corridor unit 18 forms, for example, a working platform.

The assembly of such a ladder scaffold module is described in detail below in view of the ladder scaffold module M1 shown in Fig. 3. It goes without saying that this mounting can also be carried out correspondingly in the case of modules. ladder scaffold M2, M3 located above and apply to both the ladder scaffold tower 10 of figure 2 and the ladder scaffold tower 10 of figure 1.

The ladder scaffold module M1 shown in figure 3 has, according to its rectangular perimeter contour, in each of the four module corner areas 24, 26, 28, 30, a vertical strut 32, 34, 36, 38 which in a ladder scaffold module M1 or in a mounted ladder scaffold tower 10 extends essentially vertically. The vertical struts 32, 34, 36, 38 can have, for example, a total length of 210 cm to 240 cm respectively, preferably about 220 cm. At a uniform distance of, for example, 40 to 60 cm, preferably about 50 cm, there are provided on the vertical struts 32, 34, 36, 38 five vertical strut connecting elements 40 in the form of so-called perforated discs 42. These are attached to the vertical struts 32, 34, 36, 38, which are generally tubular, that is, shaped like hollow rods, for example by welding. The vertical struts 32, 34, 36, 38 used in the four corner areas of the modules 24, 26, 28, 30 are advantageously constructed identically to each other, so that in an entire ladder scaffold tower they can be used also in the respective module corner areas 24, 26, 28, 30 vertical struts 32, 34, 36, 38 built identically to each other as well.

The mutual connection of two superimposed vertical struts 38, for example, in the corner area of module 30, is shown in Figure 4. Here one can see, for example, an end area of upper strut 44 of vertical strut 38 provided in the lowest ladder scaffold module M1 and then above, a lower strut end zone 46 of the ladder scaffold module M2 positioned on the ladder scaffold module M1. The vertical struts 38 are respectively constructed with a tubular strut body 39. A first strut body end region 45 may correspond respectively to an upper strut end region 44 of a vertical strut 38, and a second strut body end region 47 may correspond respectively to a lower strut end region 46 of a vertical strut 38. The vertical strut 38 located in the upper part of Figure 4 rests with its lower vertical strut end 48, which may correspond to a body end of strut 49 in the second strut body region 47, at the vertical strut end 50, which may correspond to a strut body end 51 in the first strut body end region 45, of the vertical strut 38 assigned to the ladder scaffold M1. To prevent mutual slippage, the vertical struts 32, 34, 36, 38 can be constructed, for example, so that coupling rods are arranged in their upper strut end regions 44 or in a respective first strut end region 45. protrude from the respective upper vertical strut end regions 50 or the first strut body ends 51, and which can be inserted into the lower strut end region 46 or the second strut body end region 47 of the vertical struts 38 positioned directly above and fixed, for example by means of shear pins.

In Figures 3 and 4 it can be seen that the perforated discs 42 provided in the respective upper strut end region 44 or in the first strut body end region 45 are arranged at a distance A1 with respect to the upper vertical strut end 50 or the first strut body end zone 51. In the same way the perforated discs 42 provided in the lower strut end zones 46 or in the second strut body end zones 37 are arranged at a distance A2 relative to the respective end vertical lower strut 48 or the second end of the strut body 49. It should be noted that these distances A1 and A2 could logically also be measured towards the center of height of the respective perforated disc 42. As will be explained later, the two distances A1 and A2 are preferably essentially identical and can be, in the case of a total length of the vertical struts 32, 34, 36, 38 of, for example, 220 cm, of the order of 10 cm, approximately amente.

The vertical struts 32, 34, 36, 38 positioned in the four module corner areas 24, 26, 28, 30 are linked together by a plurality of groups of horizontal pins. A lower group Gu of horizontal pins comprises four horizontal pins 52, 54, 56, 58 connected in the lower strut end regions 46 respectively removably to the perforated discs 42. An upper group Go of horizontal pins also comprises horizontal pins 60, 62, 64, 66 connected in the upper strut end zones 44 removably to the perforated discs 42. Between the lower group Gu and the upper group Go other groups of horizontal pins not identified with reference numbers can be connected to the discs drilled holes 42 provided in intermediate longitudinal positions of the vertical struts 32, 34, 36, 38, in order to increase the stability of the ladder scaffold modules and at the same time provide a handrail that increases safety around the perimeter of the modules of ladder scaffolding.

As illustrated in Figure 4, the horizontal pins, which are generally also provided in the form of hollow rods, shown here by means of the horizontal pins 66, 58, may have wedge-shaped heads 68 surrounding the discs in their end areas. drilled 42 similar to a fork, supported by wedges 70 that can be positioned so as to pass through the non-recognizable holes of the perforated discs 42. By moving or rotating the wedges 70 a stable connection can be established between the horizontal pins and the perforated discs 42 and, therefore, also the vertical struts 32, 34, 36, 38 that support the latter.

In order to further increase the stability of the ladder scaffold module M1 shown in FIG. 3, diagonal pins 72, 74, 76, 78 can be provided on all four sides of the rectangular perimeter contour. These can be attached, for example, to individual discs 42 in the lower strut end region 46 of a vertical strut and to separate perforated discs 42 in the upper strut end region 44 of a directly adjacent vertical strut, in a similar manner to Typically used for horizontal pins. It is also possible to couple these pins diagonals 72, 74, 76, 78 alternatively or additionally fixed to horizontal pins by clamping elements, in addition to connection to vertical struts.

The ladder unit 16 visible in figure 3 in the ladder scaffold module M1 comprises a ladder section 86 constructed, for example, with two beams 80, 82 and steps 84 extending between them. In the upper part it follows the stair section 86, in the upper stair unit end zone 20, an upper landing section 88. In the lower part it follows the stair section 86, in the stair unit end zone 22, a lower landing section 90. With the respective infill sections 88, 90 or with the hook-type connecting elements provided therein, but not shown in the figures, the ladder unit 16 can be removably coupled to the pin. horizontal 62 of the group of upper horizontal pins Go and also the horizontal pin 58 of the group of lower horizontal pins Gu positioned on the diametrically opposite side of the square perimeter contour.

The coupling of the horizontal aisle unit 18 also takes place in a similar way. In the example shown, it has two horizontal aisle plates 94, 96 placed side by side. In a first end zone of horizontal corridor unit 98 and in a second end zone of horizontal corridor unit 100, these horizontal corridor plates 94, 96 are detachably connected, for example, by means of provided hook-shaped connection elements in this regard, to the horizontal pins 54, 58 of the group of lower horizontal pins Gu located on the two diametrically opposite sides of the square perimeter contour. This results in an arrangement in which the horizontal corridor unit 18 is at the same height and laterally adjacent to the lower landing section 90 of the stair unit 16. Insofar as the same height is referred to herein Reference may be made, for example, to the free and accessible surface positioned upward of the horizontal corridor unit 18 or of the stair unit 16 in its lower landing section 90.

With the superposition of several of these stair module units M1, M2, M3 a general arrangement is obtained in which, for example, in the structure shown in figure 2, the vertical displacement between an upper landing section 88 of a ladder unit 16 at the bottom of two directly adjacent ladder scaffold modules and a horizontal corridor unit 18 at the bottom zone of the top module of the two ladder scaffold modules is roughly determined by the distances A1 and A2 between the disks holes 42, which connect the horizontal pins of the two groups of horizontal pins Gu and Go to the vertical struts 32, 34, 36, 38 with respect to the upper vertical strut end 50 and to the lower vertical strut end 48. Advantageously, these two Distances A1 and A2 are selected so that they correspond in sum approximately to the step height between two steps 84 of the stair section 86. As a consequence s e produces a corresponding spacing of the horizontal pins of the two groups Gu and Go in the adjacent area of the two modules of the ladder scaffold M1, M2, M3 in a measure corresponding to the height of the step. This in turn results in the landing section 88 of the ladder unit 16 of the ladder scaffold module M1 having a vertical spacing corresponding to the step height of the horizontal corridor unit 18 of the ladder scaffold module M2. located above, whereby reference can be made here again, for example, to the upwardly exposed and accessible surfaces of these two building groups.

When accessing the ladder scaffold tower 10 shown in FIG. 2, it is always provided where a step-like separation occurs, that is, between two directly successive steps 84 or between the upper landing section 88 and the step unit. horizontal aisle 18 next, a uniform distance, which results in a very high degree of footprint safety. The same logic proceeds in the case of the arrangement of the ladder scaffold tower 10 shown in Figure 1. In this figure, a lower landing section 90 respectively adjacent to an upper landing section 88 has, due to the relative height positioning of the two groups Go and Gu of horizontal pins, a vertical distance corresponding to the step height in the respective stair sections 86.

This horizontal spacing also ensures that, in case of a standard height of the stair units between the upper landing section and the lower landing section of about 2 meters, adapted to the height distance of the perforated discs 42 provided in the upper strut end zones 44 and the lower strut end zones 46, the height distance of the overlapping ladder scaffolding modules M1, M2, M3 from the directly overlapping ladder units 16 is, in the case of the complete structure with stair units 16 located in the same direction shown in figure 2, greater, that is, increased by a distance that fundamentally corresponds to the sum of the two distances A1 and A2.

It should also be noted that the ladder scaffold modules M1, M2, M3 illustrated in the ladder scaffold tower 10 of figure 1 may have the structure described in figure 3. Only the horizontal corridor units 18 are not provided in Figure 1. To increase safety when accessing the stair units 16, as in the stair units 16 of the stair scaffold tower 10 of Figure 2, handrails 102 and / or 104, which extend along the respective stair section 86 and prevent a side fall.

With the structure described above it is possible to construct ladder scaffolding modules in a simple, but also stable and design-variable manner, which, after individual assembly, can be stacked on top of each other, for example by means of a construction crane. , to create a ladder scaffold tower of any height. For ladder scaffolding modules, uniform components for stair scaffolding modules can be used which, thanks to the fact that practically all components, such as struts vertical, horizontal pins, diagonal pins, stair units and horizontal corridor units, can be separated from each other, can be stored in a small space or transported to a place of use.

It should be noted that, of course, in the assembly of a ladder scaffold module of this type, multiple variations can be envisaged. Therefore, it is not necessary for each group of horizontal pins to comprise four of these horizontal pins. In any case, it is important that for the coupling of the stair units or horizontal corridor units to two diametrically opposite sides of the generally square or rectangular perimeter contour of the stair scaffold modules, a horizontal pin is respectively arranged in the zone lower, that is, in the lower group of horizontal pins, and a horizontal pin in the upper area, that is, in the upper group of horizontal pins. For stability reasons it is logically advantageous to provide four horizontal pins in each one or at least in the upper and lower groups of horizontal pins. However, as especially illustrated in FIG. 3, one of these groups of horizontal pins need not actually be arranged in assignment to each perforated disc intended for engagement of horizontal pins in the vertical struts.

Furthermore, in the case of the basic structure built from vertical struts and horizontal pins and, where appropriate, diagonals, on which the stair units or horizontal corridor units rest, it can be foreseen that, depending on the required module size, more vertical struts are arranged on different sides of the perimeter contour in sections located between the corner areas of the module, so that, for example, modules of greater length and / or width can be built. Vertical struts can also be divided and composed, for example, of several strut sections, for example two sections.

It should also be noted that in a ladder scaffold tower the construction method illustrated in figure 1 with ladder units arranged in opposite directions and directly in succession can be combined with the construction method illustrated in figure 2 with ladder units overlapping and oriented in the same direction. It is also possible that in a ladder scaffold tower with several of the ladder scaffold modules described above, other non-modular building modules or sections are arranged or incorporated. For example, once a ladder scaffold tower is finished, the railing unit explained above could be mounted on the tower itself by stacking different ladder modules on top of each other in the upper end zone, i.e. on the ladder scaffold module. higher, and not necessarily also in a modular way, being assembled first on the ground and then placed as a finished module on the highest of the ladder scaffolding modules.

In the case of ladder scaffolding modules, the assembly could be carried out in such a way that the horizontal corridor units are respectively assigned to the upper ladder unit end zone of the ladder unit provided in such a module. , that is, they will be coupled to it at the same height in two horizontal pins of the upper group of horizontal pins. At the lowest of the superimposed staircase scaffold modules, for example, in assignment to the upper stair unit end area and to the lower stair unit end area, a horizontal corridor unit could be provided.

The vertical struts used for the construction of ladder scaffolding modules are advantageously constructed so that they are symmetrical with each other at least in their two strut end zones or strut body end zones, that is, the perforated discs provided in the respective end zones or, the vertical strut connection elements constructed, where appropriate, differently, have an equal distance in relation to the respective end of the rod or the rod body. Accordingly, the vertical strut connecting elements distributed through the length of the vertical struts or their strut bodies also advantageously have a uniform distance from each other, whereby the two strut ends or the strut body ends have , for example, relative to the center of length, a fundamentally symmetrical structure. Obviously, it is also possible to provide a variant that differs from this symmetrical configuration, in which, for example, the vertical strut connecting the vertical strut connection elements provided in the two strut end zones or in the body end zones strut body end regions of the strut have a different distance from the respectively assigned strut end or strut body end, however it is advantageous that the distance between such a vertical strut connecting element and the end Strut length or the assigned strut body end does not exceed a predetermined maximum measurement of, for example, 20 cm.
