Description

The invention relates to a lifting drive for a rail-guided climbing system, which can be used in particular as climbing formwork, climbing frame, climbing protection wall and / or climbing work platform, with climbing shoes that can be arranged in a stationary manner on a structure, and at least one climbing rail guided by the climbing shoes, which is in a scaffolding unit can be integrated or attached to the scaffolding unit. The invention further relates to a rail-guided climbing system with this lifting drive and a method for climbing a rail-guided climbing system, which can be used in particular as climbing formwork, climbing frame, climbing protection wall and / or climbing work platform, with this lifting drive.

Such lifting drives with hydraulic cylinders are in the German laid-open application DE 10 2016 205 956 A1 and in the international disclosure document WO 2009/117986 A1 described as state of the art for a climbing system. In the construction industry, climbing systems are used e.g. B. in the construction of vertically oriented concrete structures, in particular so-called building cores, bridges, dams and the like Climbing formwork and/or climbing protection walls and/or used in the form of climbing frames. The climbing systems are usually provided with a work platform as a scaffolding unit and can be moved independently of a crane from a lower completed concrete wall section of the concrete structure to be created or completed to a hardened further concreting section of the concrete structure arranged above it. A climbing rail can then be moved upwards, i.e. climbed, using a hydraulic cylinder that is supported on a climbing shoe. Alternatively, a work console or work platform can be raised using climbing cylinders, which are attached to a climbing console that is attached to a concrete wall using anchor bolts below the work console and to the work console. In addition, sick climbing systems are known that work without hydraulic cylinders.

A disadvantage of the known lifting drives for climbing systems is that the hydraulic cylinder has to be carried to the next higher floor each time for the next climbing section or concreting section. Depending on the lifting drive used, a leading rail may also be necessary, which must be attached manually to the structure, whereby the climbing direction on the climbing system must be switched manually while climbing in order to tighten the rail. The manual effort is therefore high after each lifting process, and continuous climbing is not possible. In addition, existing lifting drives for rail-guided climbing systems can be made so large that when using the climbing system, due to the length of the climbing rails, a building height must first be reached that is sufficient so that the lower free ends of the climbing rails do not come into contact with the ground on which the first concreting section is built or a floor ceiling that can be built below the first concreting section, collide. Climbing systems driven by geared motors, on the other hand, are expensive and prone to repairs, so drives with gears cannot provide an adequate alternative to the much simpler lifting drives.

The document KR 20090020246 discloses a lifting drive according to the preamble of claim 1.

The object of the present invention is, in contrast, to provide a simply constructed lifting drive that enables continuous climbing. In addition, a lifting drive is to be provided with which gradual, continuous climbing is possible without the previously required high manual effort after each lifting process. Ultimately, the lifting drive should have a compact design so that it can be used as versatile as possible with a rail-guided climbing system.

This object is achieved by a lifting drive with the features of patent claim 1 and a method for climbing a rail-guided climbing system with the features of patent claim 14. The subclaims indicate appropriate further training.

The object according to the invention is thus achieved by a lifting drive for a rail-guided climbing system, which can be used in particular as climbing formwork, climbing frame, climbing protection wall and / or climbing work platform, with climbing shoes that can be arranged in a stationary manner on a structure, at least one climbing rail guided by the climbing shoes can be integrated into a scaffolding unit or can be attached to the scaffolding unit, a climbing lifting rail which is displaceable relative to the climbing rail and is guided by the climbing rail. The climbing rail and the climbing lifting rail can each be hooked into at least one of the climbing shoes in one direction and in this direction can be unhooked in the opposite direction and moved relative to at least one of the climbing shoes. The lifting drive further comprises a lifting device which is fixed at one end to the climbing rail and at the other end to the climbing lifting rail in such a way that a length of a stroke of the lifting device corresponds to a displacement of the climbing lifting rail relative to the climbing rail. When the climbing lifting rail is attached, the length of the stroke of the lifting device is sufficient to hang the climbing rail offset by a hanging distance of the climbing rail.

According to the invention, a climbing lifting rail is provided as a unit guided by the climbing rail and displaceable relative to the climbing rail, which is connected to the climbing rail via the lifting device. So a climbing lifting rail, which is limited in its movement by the climbing rail and moves up and down relative to the climbing rail, is movably connected to the climbing rail. The climbing lifting rail is held or guided on the climbing rail, for example, via guide shoes of the climbing rail. A movement of the climbing lifting rail relative to the climbing rail is realized by a retractable and extendable lifting device. The lifting device can be releasably fixed to the climbing rail at its upper or lower end, i.e. at one end, whereby the lifting device can have an engagement and fastening tab at its lower or upper end, i.e. at the other end, which is connected to the climbing rail is firmly connected, i.e. not easily detachable.

In order to achieve an upward movement of the climbing rail both when extending and retracting the lifting device, the length of the stroke of the lifting device is selected so that it is sufficient to hang the climbing rail offset by a hanging distance of the climbing rail. Je After executing the connection between the climbing shoe and the climbing rail for hanging the climbing rail, at least one hanging distance of the climbing rail must be covered by the lifting device when the climbing lifting rail is suspended. With the upward movement of the climbing rail relative to the structure when extending and the upward movement of the climbing lifting rail relative to the climbing rail when retracting the lifting device, continuous climbing of the scaffolding unit is achieved in a simple manner. The lifting drive according to the invention therefore climbs due to its lifting movements. Since the climbing rail and the climbing lifting rail can each be hooked into at least one of the climbing shoes in one direction and can be unhooked in the direction opposite to this direction and can be moved relative to the at least one of the climbing shoes, manual effort can be dispensed with in each extension and retraction step of the lifting device. The lifting device no longer needs to be dismantled and carried to the next higher floor for the next climbing section or concreting section.

The climbing lifting rail is guided by the climbing rail when the climbing lifting rail is moved relative to the climbing rail, so that it is ensured that the respective dimensions of the climbing rail and the climbing lifting rail do not add up in the longitudinal direction, even when the lifting device is fully extended, resulting in a compact structure of the lifting drive leads. Since the lifting device can remain fixed at one end to the climbing rail and at the other end to the climbing lifting rail both when retracting and extending and, apart from the guidance of the climbing rail, the climbing lifting rail is only connected to the climbing rail via the lifting device, the lifting drive is very simply constructed and correspondingly inexpensive Realizable, operable with low losses and not susceptible to repairs.

In a preferred embodiment of the invention, the length of the stroke is also sufficient to cover a hook-in stroke distance of the climbing lifting rail. In this way, the climbing rail can be hung offset by the hanging distance, even if a complete hanging stroke distance of the climbing lifting rail has to be covered beforehand in order to hang the climbing lifting rail. The suspension stroke distance can be chosen to be smaller than the suspension distance in order to use a larger part of the full length of the stroke of the lifting device for the upward movement of the climbing rail relative to the structure than for the downward movement of the climbing lifting rail relative to the climbing rail.

The climbing shoe, from which the climbing rail is guided when the climbing lifting rail is suspended, can be arranged above or below the climbing shoe into which the climbing lifting rail is suspended. According to the exemplary embodiments described with reference to the figures, the climbing shoe, by which the climbing rail is guided when the climbing lifting rail is suspended, is arranged above the climbing shoe into which the climbing lifting rail is suspended, which is therefore not necessary.

The climbing shoe can be designed either for hanging the climbing rail or the climbing lifting rail or for hanging both the climbing rail and the climbing lifting rail. In this way, conventional climbing shoes can be used to attach the climbing rail. On the other hand, the size and in particular the required number of climbing shoes can be reduced if the climbing shoe is designed to hang both the climbing rail and the climbing lifting rail.

The connection between the climbing lifting rail and the climbing shoe is preferably made in such a way that the climbing lifting rail is inserted into the climbing shoe designed for hanging the climbing lifting rail by means of at least one latching/snapping element and a plurality of holding elements for holding the at least one latching/snapping element or by means of a plurality of latching /Snap elements and at least one holding element for holding at least one latching/snapping element of the plurality of latching/snapping elements. Here, the one or more latching/snapping elements are located on the climbing shoe designed for hanging the climbing lifting rail and the one or more holding elements are on the climbing lifting rail, or the one or more holding elements are on the climbing shoe designed for hanging the climbing lifting rail and the one or more latching/snapping elements are on the Climbing lifting rail. In this way, the climbing lifting rail with the climbing shoe can be manufactured easily and reliably.

The latching/snapping element is designed as a movable element, which is in particular designed to be pivotable, foldable or displaceable, in the form of a pawl, in particular a latching pawl or climbing pawl, a detent, in particular a latching lug, or a bolt, in particular a latching bolt. On the climbing lifting rail, the latching/snapping elements will be one behind the other in the form of climbing latches or folding latching lugs. Alternatively, the holding elements in the form of holding recesses are introduced one behind the other into the climbing lifting rail for engagement with the at least one latching/snapping element of the climbing shoe, as is given below in the embodiments described with reference to the figures, or holding nubs are applied to the climbing lifting rail, for example welded on.

In a preferred embodiment, the climbing lifting rail has the holding recesses on at least one side such that the climbing lifting rail is in the form of a profile with a hanging contour, in particular with teeth. Alternatively, in particular if there is only a latching/snapping element on the climbing shoe designed for hanging the climbing lifting rail, the climbing lifting rail can have the holding recesses in the form of completely bordered holes, also called ears. Completely bordered holes as holding recesses have greater stability than not completely bordered recesses between teeth, especially if only one latching/snapping element has to support the climbing system when the lifting device is extended. On the other hand, serrations that arise between rectangular or square recesses, for example, are easier to manufacture and therefore more cost-effective than hole patterns. The climbing lifting rail can be used depending on the application, e.g. B. required stability and / or cost specification, made from solid material, for example pressed or embossed, or present as a hollow profile, for example in lasered form.

A latching/snapping element arranged in or on the climbing shoe is preferably designed in the form of a climbing latch for hanging both the climbing rail and the climbing lifting rail. Because of the dual function of this climbing latch, the climbing shoe can be set up more easily than in the case in which a climbing latch has to be provided for hanging the climbing rail and the climbing lifting rail.

Depending on the application, the climbing rail and the climbing lifting rail can be arranged one inside the other or lying next to one another.

When arranged one inside the other, the guidance of the climbing lifting rail by the climbing rail may be more effective than when arranged next to one another, which can be easier to implement than the one inside the other.

The climbing lifting rail preferably has a rectangular profile or cross-sectional profile in the shape of an L, T or I, also called a double T. This ensures a simple and stable design of the climbing lifting rail.

A hydraulic cylinder, spindle drive or rack drive can be used as the lifting device, whereby the spindle or rack drive can be driven by an electric motor, for example, an actuator or a linear drive. According to the invention, an ordinary standard hydraulic cylinder can therefore be used.

If the climbing rail is designed to be pivotable by at least 4 degrees relative to a vertical axis, the lifting drive is also suitable for creating non-vertical designs of the outer wall or outer walls of a building without modifications.

The invention also includes a rail-guided climbing system with the lifting drive according to the invention, the scaffolding unit, into which at least one of the climbing rails is integrated or to which the at least one climbing rail is attached, with a total length of the at least one climbing rail being sufficient to guide the climbing rail of at least two climbing shoes , which are spaced apart from each other at a predetermined distance. By using several climbing rails at the same time, the load-bearing capacity of the climbing system can be increased. To completely cover a building with a climbing system provided, it may be necessary to provide a large number of climbing rails for the climbing system. The heights of several climbing rails are preferably synchronized via an end position compensation after each extension and retraction of the lifting device.

The at least two climbing shoes are preferably spaced apart from one another at a distance which corresponds approximately to a floor height of the structure or a fraction thereof. With a spacing of approximately one floor height, the climbing shoes can be placed or removed in the outer wall of the structure with each climbing cycle with which the climbing system is moved up one floor height. Intermediate climbing steps just to put on or remove the climbing shoes without any further work, such as formwork, concreting, etc., can be avoided.

A method for climbing a rail-guided climbing system, which can be used in particular as climbing formwork, climbing frame, climbing protection wall and/or climbing work platform, with the lifting drive according to the invention is also part of the invention. The procedure includes the steps:

• Extending the lifting device with the climbing rail attached, the climbing lifting rail being moved downwards relative to the climbing rail until the climbing lifting rail is attached,
• Continuing the extension movement of the lifting device, whereby a further downward displacement of the climbing lifting rail is prevented by the successful hanging of the climbing lifting rail and the climbing rail is unhooked and moved upwards by at least one hooking distance of the climbing rail relative to the climbing lifting rail,
• Retracting the lifting device, the climbing rail being displaced downwards relative to the climbing lifting rail until the climbing rail is suspended upwards by at least one hooking distance, and
• Continuing the retraction movement of the lifting device, whereby a further downward displacement of the climbing rail is prevented by the successful hanging of the climbing rail and the climbing lifting rail is unhooked and moved upwards relative to the climbing rail by at least the one hanging distance of the climbing rail.

For example, the lifting device extends until the lower one of at least three climbing shoes, which are able to guide the climbing rail at the same time, is hooked into the climbing lifting rail. A further downward movement of the climbing lifting rail relative to the structure is then no longer possible and the further stroke of the lifting device pushes the climbing rail, to which the scaffolding unit is attached, over the climbing lifting rail, which is now stationary relative to the building and is connected to the lifting device, in the direction the climbing rail upwards in the opposite direction until it is hooked in. The climbing rail is therefore supported by the lifting device on the climbing lifting rail in order to move the climbing system upwards. The climbing rail is thereby lifted out of the middle of the three climbing shoes for guiding the climbing rail, which was previously responsible for the vertical load transfer, and the vertical load is transferred in the lower climbing shoe, into which the climbing lifting rail is suspended. Since the length of the stroke of the lifting device is sufficient to hang the climbing rail offset by a hanging distance, the climbing rail passes over the upper of the three climbing shoes. After the climbing stroke has been completed, the vertical load entry changes when the lifting device is retracted lower onto the upper climbing shoe, into which the climbing rail is now hooked. Other embodiments are possible, whereby any climbing shoe of the climbing lifting rail that is located in the area of the climbing lifting rail can be used to push upwards. In the above exemplary embodiment, the climbing shoe with a holding function for holding the climbing rail is located above the climbing shoe for hanging and supporting the climbing lifting rail. The climbing shoe with a holding function for holding the climbing rail, which can be designed as a climbing shoe with an additional latch, can, however, be arranged anywhere relative to the climbing shoe for hanging and supporting the climbing lifting rail, e.g. B. in the area of the middle climbing shoe or below the climbing shoe for hanging and supporting the climbing lifting rail.

The method steps according to the invention are preferably defined as a cycle and the cycle is repeated until the scaffolding unit has reached another or more additional floors of the building or a section of the building to be concreted.

Fig. 1a shows a starting position of a climbing system 10 with the lifting drive according to the invention in cross section in a sequence of Climbing processes for climbing a scaffolding unit 11 around a floor of a building 1. The building 1 comprises several floors with outer walls 40, 44, 48, 52, which in the cross-sectional view through cutouts 41, 45, 49, 53, for example for installing windows vertical direction Y are shown separately from each other. The floors of building 1 lying one above the other with floor heights 42, 46, 50, 54 are connected to one another by floor ceilings 43, 47, 51, 55.

The climbing system 10 comprises a scaffolding unit 11 with a formwork platform 12 with a formwork 13, which can be moved together in the horizontal direction 14 towards the building 1 and/or away from the building 1 in order to complete a concreting section, for example of a floor of the building 1. Below the formwork platform 12 there is a work platform 16 which is fixed to the formwork platform 12. A control unit for operating a drive for moving the formwork and/or a lifting device 26 for climbing the climbing system can be arranged on the work platform 16. The lifting device 26 is located on a follow-up platform 22 arranged below the work platform 16 and fixed to the work platform 16. The scaffolding unit 11 therefore comprises in the in Fig. 1a Climbing system 10 shown, the formwork platform 12, the work platform 16 and the trailing platform 22, with a climbing rail 18 being integrated into the scaffolding unit 11. Attaching the climbing rail 18 to the scaffolding unit 11 is also possible. The trailing platform 22 serves, among other things, for attaching and removing climbing shoes 32, 34, 36, 38, which are arranged in a stationary manner on the structure 1 and serve to guide and support the climbing rail 18, which carries the scaffolding unit 11.

The climbing rail 18 has bores 19 and support bolts 19' which are vertically spaced apart from one another at a hanging distance 20, also called spacings, which engage in each of the climbing shoes 32, 34, 36, 38 in such a way that the climbing rail 18 each fits into at least one of the climbing shoes 32 , 34, 36, 38 in the vertical direction, e.g. B. when moving downwards, can be hooked in and in the opposite direction to this direction, i.e. upwards, can be unhooked and moved relative to the respective climbing shoe 32, 34, 36, 38.

According to the invention, not only the climbing rail 18, but also a climbing lifting rail 24, which is displaceable relative to the climbing rail 18 and guided by the climbing rail 18, is present, each of which can be hooked into at least one of the climbing shoes 32, 34, 36, 38 in one direction and in can be unhooked in the opposite direction to this direction and displaceable relative to at least one of the climbing shoes 32, 34, 36, 38. In addition to being guided by the climbing rail 18, the climbing lifting rail 24 is only connected to the climbing rail 18 via the lifting device 26. In the present exemplary embodiment, the lifting device is connected with its lower end 27 to the climbing lifting rail 24 and with its upper end 28 to the climbing rail 18.

At the beginning of the climbing process, the lifting device, more precisely a lifting cylinder or stamp of the lifting device, is completely retracted, so that a stroke length 2 of the lifting device is zero. When the lifting device 26 is retracted, there is a distance 2' between a height 25 of an upper edge of the climbing lifting rail 24 and that of a height 21 of an upper edge of the climbing rail 18. The climbing rail 18 is suspended in the climbing shoe 34, so that vertical load transfer takes place via this climbing shoe.

In Fig. 1b the lifting device 26 is extended by a stroke length 3 that is not equal to zero. The climbing rail 18 is still suspended in the climbing shoe 34 and the climbing lifting rail 24 moves downwards in such a way that the height 25a of the upper edge of the climbing lifting rail 24 is a distance 3 'from the height 25 of the climbing lifting rail 24, which is in Fig. 1a shown is shifted downwards. Since the climbing rail 18 is in relation to its height Fig. 1a has not moved, the length 3 of the stroke of the lifting device 26 corresponds to the displacement 3 'of the climbing lifting rail 24 relative to the climbing rail 18. The lifting device 26 extends until the climbing lifting rail 24 is hooked into the climbing shoe 32, which, however, in Fig. 1b is not yet the case.

In Fig. 1c the lifting device 26 is extended by the stroke length 4, which is greater than the stroke length 3, so that the climbing lifting rail 24 is now hooked into the climbing shoe 32. Because the climbing lifting rail 24 cannot move further downwards due to its attachment to the climbing shoe 32, the climbing rail 18 is now moved upwards instead of the climbing lifting rail 24. This means that the entire climbing system 10 including the scaffolding unit 11 is raised upwards. Compared to the height 21 of the top edge of the climbing rail 18 in Fig. 1a and Fig. 1b is the height 21a of the upper edge of the climbing rail in Fig. 1c shifted upwards by a distance of 4'. The length 4 of the stroke of the lifting device 26 is therefore composed of the distance 3 'by which the climbing lifting rail 24 is relative to its height Fig. 1a has moved downwards, and from the distance 4 'by which the climbing rail 18 relative to its height in Fig. 1a moved up. The length 4 of the stroke of the lifting device 26 is sufficient with the climbing lifting rail 24 attached to hang the climbing rail 18 in the climbing shoe 36 offset by the hanging distance 20. At least the hanging distance 20 is covered. The lifting device 26 So pushes the climbing rail 18, supported on the climbing lifting rail 24, which is supported on the lower climbing shoe 32, upwards by at least the hanging distance 20. In the case of Fig. 1c the climbing rail 18 is offset by the hanging distance 20 and additionally by a breakpoint distance that is required to hang the climbing rail 18 in the climbing shoe 36. The holding point of the climbing shoe 36 from the climbing rail 18 is climbed over in order to be able to hang the climbing rail 18 in this climbing shoe. The support bolt 19 'of the climbing rail 18 is therefore located above a hanging height 36' of the climbing shoe 36. The breakpoint distance is approximately the vertical distance between two adjacent bores 19 of the climbing rail 18. In other embodiments, the breakpoint distance can be smaller or reduced to zero. In this case, it is sufficient if the lifting length 4 can cover the hanging distance 20 of the climbing rail 18 when the climbing lifting rail 24 is attached. Since the climbing rail can be moved upwards by the hanging distance 20, it is not necessary to provide a stroke length greater than the stroke length 4. The stroke length 4 is therefore the maximum stroke length in the present exemplary embodiment. Higher maximum stroke lengths are still possible.

In Fig. 1d the lifting device 26 is retracted so that the stroke length 5 is smaller than the stroke length 4 in Fig. 1c . Compared to the height 21 of the top edge of the climbing rail 18 in Fig. 1a and Fig. 1b the height 21b of the upper edge of the climbing rail is shifted upwards by the distance 5'. This distance is smaller than the distance 4' in. by the breakpoint distance Fig. 1c and is the hanging distance 20, so that the climbing rail 18 is hooked into the climbing shoe 36. This can be seen from the fact that the support bolt 19 'is at the height of the hanging height 36' of the climbing shoe 35. Since the lifting device 26 with the stroke length 5 is more than the stopping point distance compared to the stroke length 4 is retracted and the climbing rail 18 cannot move further downwards due to its hooking into the climbing shoe 36, the climbing lifting rail 24 is now moved upwards instead of the climbing rail 18. Compared to the height 25 of the top edge of the climbing lifting rail 24 in Fig. 1a the height 25b of the upper edge of the climbing lifting rail is only a distance of 5" downwards, whereby this distance is smaller than the distance 3' in Fig. 1b and Fig. 1c . The length 5 of the stroke of the lifting device 26 is made up of the distance 5" by which the climbing lifting rail 24 is relative to its height Fig. 1a has moved downwards, and from the distance 5 'by which the climbing rail 18 is relative to its height Fig. 1a moved up. Without moving the scaffolding unit 11, which is suspended in the climbing shoe 36 via the climbing rail 18, the climbing lifting rail 24 is pulled upwards.

In Fig. 1d the lifting device 26 is completely retracted. Therefore the stroke length 2 is zero. As in Fig. 1c shown, the height 21b of the upper edge of the climbing rail 18 is shifted upwards by the distance 5 ', which corresponds to the hanging distance 20. The support bolt 19 'is at the height of the hanging height 36' of the climbing shoe 35 and the climbing rail 18 is at the hanging distance 20 compared to its height Fig. 1a offset upwards, as in a comparison of the heights 21 and 21b of the upper edges in Fig. 1a and Fig. 1d can be recognized. The height 25c of the upper edge of the climbing lifting rail 24 is also 25 inches compared to its height Fig. 1a around the hanging distance 20, which is a distance of 5‴ in Fig. 1d is shown, offset upwards so that the distance 2" of the upper edges 21b and 25c of the climbing rail from the climbing lifting rail is the distance 2' in Fig. 1a corresponds. The climbing rail 18 therefore hangs when the lifting device 26 is retracted Fig. 1d in the climbing shoe 36. In Fig. 1a The climbing rail 18 hung in the climbing shoe 34 when the lifting device 26 was retracted.

Fig. 2 shows that in Fig. 1b Climbing system 10 shown in a side view. The climbing lifting rail 24 lies in the climbing rail 18 in such a way that the climbing lifting rail cannot be seen. The formwork 13 is mounted on a vertical support 13 'for the formwork. A 13" railing is attached to the upper end of the vertical beam 13' to ensure safe work in this area.

In Fig. 2b is a top view of the in Fig. 1b and 2a Climbing system 10 shown with two climbing rails 18 arranged parallel to one another. In addition to the formwork platform 12, the work platform 16 and the trailing platform 22, the formwork 13 with vertical support 13 'and railing 13" as well as the cutouts 41, 45, 49 in the outer wall 44 of the building 1 shown.

Fig. 3a shows section B of the lower area in Fig. 2a in an enlarged view in cross section. In this respect shows Fig. 3 the one already in Fig. 1b shown section with guide shoes 19" of the climbing rail 18, in which the climbing lifting rail 24 are guided. The climbing rail 18 is suspended in the climbing shoe 34, with the support bolt 19 'being suspended approximately centrally in the vertical direction to the climbing shoe 34.

Fig. 3b shows in cross section along plane AA in Fig. 3a the climbing rail 18, which comprises two opposing U-shaped elements, and the climbing lifting rail 24, which has an I-shaped cross section, also called a double T-shaped cross section. The climbing lifting rail 24 is arranged in the climbing rail 18 between the U-shaped elements of the climbing rail 18 and by guide shoes 19", which are also between the U-shaped elements the climbing rail 18 are arranged, guided. The guide shoe 19" only guides the side of the climbing lifting rail 24 facing away from the outer wall 40, whereby the side of the climbing lifting rail 24 facing the outer wall 40 can engage in a climbing pawl 32", which is in Fig. 3b can be seen because in addition to the cross section of the climbing rail and climbing lifting rail, a top view of the climbing shoe 32 is shown. The climbing latch 32" has two lugs arranged parallel to one another, which can engage in the side of the climbing lifting rail 24 facing the outer wall. The climbing shoe 32 has two legs 32 'with which the side of the climbing rail 18 facing the outer wall 40 is guided.
