Description

The invention relates to an arrangement of a climbing rail and a climbing lifting rail, which can be displaced relative to the climbing rail and is guided by the climbing rail, for a rail-guided climbing system which can be used in particular as a climbing formwork, climbing scaffold, climbing protection wall and/or climbing work platform, the climbing system being used for climbing shoes , which can be arranged in a fixed manner on a structure, and comprises a lifting device which is fixed at one end to the climbing rail and at the other end to the climbing lifting rail. The invention further relates to a rail-guided climbing system with this arrangement and a method for climbing a rail-guided climbing system, which can be used in particular as climbing formwork, climbing scaffold, climbing protection wall and/or climbing work platform, with this arrangement.

A rail-guided self-climbing formwork system is in the international patent application WO 2009/11 7986 A1 and in the Publication WO 2018/190584 A1 described as state of the art for a climbing system. In construction, 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, used as climbing formwork and / or climbing protection walls and / or in the form of climbing frames. The climbing systems are usually provided with a working platform as a scaffolding unit and can be moved, independently of a crane, from a lower, finished concrete wall section of the concrete structure to be created or finished to an overlying, hardened further concrete section of the concrete structure. After that, a climbing rail, which is supported by a hydraulic cylinder supported by a climbing shoe, can be moved upwards, i.e. climbed. Alternatively, raising a work console or work platform can be achieved by means of climbing cylinders which are attached to a climbing console fixed in a concrete wall by means of 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 for the next climbing section or concreting section. Depending on the lifting drive used, a leading rail may also be necessary, which must be manually attached to the structure, with the climbing system having to be switched over by hand when climbing in order to pull the rail. The manual effort is therefore high after each lifting process, with continuous climbing not being possible.

The climbing systems provided with a working platform as a scaffolding unit can only be used for shuttering after moving from a lower finished concrete wall section to an overlying further concreting section of the concrete structure when the further concreting section has fully hardened. Because only then can a climbing shoe reliably absorb the vertical load of the climbing rail to which the scaffolding unit is attached. Waiting for the concrete to fully harden before the next shuttering process costs time and thus drives up costs on the construction site. If the formwork was switched on while the climbing rail was supported on a climbing shoe that was anchored in a concrete section that was not fully hardened, this could lead to the climbing shoe shifting in the concrete due to the concrete's insufficient load-bearing capacity and, in the worst case, to the climbing rail falling with the scaffolding unit guide the climbing shoe.

In contrast, the object of the present invention is to provide a simple and compact arrangement with a climbing rail for a climbing system that enables step-by-step, continuous climbing without a great deal of manual effort after each lifting process in such a way that after the climbing process has been completed without waiting for the entire curing time of the last completed concreting section, the next concreting section to be completed can be shuttered with the climbing system. In particular, it should allow the arrangement with a climbing rail for a climbing system, immediately after climbing over a recently completed one hardened concreting section to form the next concreting section to be completed with the climbing system.

This object is achieved by an arrangement with a climbing rail having the features of patent claim 1 and a method for climbing a rail-guided climbing system having the features of patent claim 17 . The subclaims indicate appropriate developments.

The object according to the invention is thus achieved by an arrangement of a climbing rail and a climbing lifting rail, which can be displaced relative to the climbing rail and is guided by the climbing rail, for a rail-guided climbing system which can be used in particular as a climbing formwork, climbing scaffold, climbing protection wall and/or climbing work platform. wherein the climbing system comprises climbing shoes, which can be arranged in a stationary manner on a structure, and a lifting device which is fixed at one end to the climbing rail and at the other end to the climbing lifting rail, the climbing rail being guided by the climbing shoes, the climbing rail and the climbing lifting rail each being in one Climbing direction can be hooked into at least one of the climbing shoes in the opposite direction and can be detached in the climbing direction from the at least one of the climbing shoes and can be displaced relative to the at least one of the climbing shoes, with a fixing means being provided to fix the climbing rail and the climbing lifting rail to one another independently of being fixed to one another by the lifting device to be reversibly fixed to one another.

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. A climbing lifting rail, which is restricted 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 controlled by a lifting device that can be retracted and extended realized. The lifting device can be releasably fixed to the climbing rail at its upper or lower end, i.e. one end, with the lifting device having an engagement and fastening strap at its lower or upper end, i.e. the other end, i.e. the other end, which is connected to the climbing rail fixed, so not easily solvable connected. The climbing direction can indicate an upward direction, ie an upward direction, although a sideways direction is also possible, for example in tunnel construction. Oblique linear translational or also curved, for example rotational, directions are possible as a climbing direction.

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 can be chosen so that it is sufficient to mount the climbing rail offset by a hanging distance of the climbing rail. Depending on the design of the connection between the climbing shoe and the climbing rail for hanging the climbing rail, at least one hanging distance of the climbing rail and also a climbing shoe travel distance of the lifting device should preferably be covered when the climbing lifting rail is hooked. The climbing shoe crossing path in the climbing direction is used in a climbing shoe to cause a hanging in the climbing shoe after crossing this crossing path during a movement in the direction opposite to the climbing direction. 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 with 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 unhooked in the opposite direction to this direction and can be displaced relative to at least one of the climbing shoes, there is no need for manual effort after each extension and retraction step of the lifting device. The lifting device no longer has to be dismantled and carried to the next floor up for the next climbing section or concreting section.

The climbing lifting rail is guided by the climbing rail when the climbing lifting rail is displaced relative to the climbing rail, so that it is ensured that the respective expansions of the climbing rail and the climbing lifting rail in the longitudinal direction do not add up even when the lifting device is fully extended, resulting in a compact design of the lifting drive leads. Since the lifting device can remain fixed at one end on the climbing rail and at the other end on the climbing lifting rail both when retracting and extending and apart from the guidance of the climbing rail and the independent fixing means with regard to the lifting device for the reversibly detachable fixing of the climbing rail and the climbing lifting rail to one another only via the climbing lifting rail the lifting device is connected to the climbing rail, the lifting drive is of extremely simple design and can be implemented correspondingly inexpensively, can be operated with low losses and is not prone to repairs.

If the climbing lifting rail is reversibly and detachably fixed to the climbing rail with the fixing means according to the invention, a vertical load on the climbing rail, for example a scaffolding unit and/or protective wall, into which the at least one climbing rail is integrated or to which the at least one climbing rail is attached, can be the climbing lifting rail and a climbing shoe, in which the climbing lifting rail is suspended, are derived into the structure. This condition can last for the duration of a formwork that is carried out using the climbing system, because the lifting device does not have to fix the climbing lifting rail to the climbing rail and is therefore freed from the vertical load to be introduced into the structure and hanging on the climbing rail. The lifting device can consequently be dimensioned in such a way that it only has to accompany the climbing process, but not the shuttering process that follows the climbing process.

If, during operation of the climbing system, the climbing lifting rail is suspended in at least one climbing shoe, the climbing lifting rail is thus reversibly detachable and fixed to the climbing rail by means of the fixing means, independently of any further fixing of both rails by the lifting device, i.e. independently of the lifting device, in order to immediately then to be able to start the shuttering. The fixing means is of the lifting device with regard to its fixing effect both rails independently of each other, i.e. mechanically. The fixing means can also fix the two rails to one another in a reversibly detachable manner when the lifting device is not in operation, or in other words, when there is no lifting device. However, there may be a temporal dependency of the fixing by the fixing means on the operation of the lifting device. An operation of the fixing means can therefore depend on an operating state of the lifting device or a movement of the lifting device in terms of time and control technology.

The climbing shoe into which the climbing rail was hooked before the climbing lifting rail was hooked in by extending the lifting device, whereby the climbing rail was unhooked, can be located further in the climbing direction than the climbing shoe into which the climbing lifting rail is hooked by extending the lifting device. According to the invention, it is provided that the climbing shoe, into which the climbing rail was suspended before the climbing lifting rail was suspended by the extension of the lifting device, is anchored in a concrete that has not yet fully hardened and the climbing shoe into which the climbing lifting rail was fixed independently of the lifting device hooked into the climbing rail is anchored in a previously completed concreting section with fully cured concrete. In this case, immediately after climbing over the last completed concreting section that has not yet fully hardened, which is indicated by the hanging of the climbing rail into the climbing shoe of this concreting section, the next concreting section to be completed can be shuttered with the climbing system, because the climbing system cannot withstand the vertical load during shuttering into this climbing shoe, but rather into the next climbing shoe, which is arranged counter to the climbing direction relative to this climbing shoe and is anchored in an already fully cured concreting section.

After the climbing rail has been hooked into the next climbing shoe of a fresh and therefore not yet fully hardened concreting section, no vertical loads occur in this shoe during a shuttering process for shuttering the next concreting section that has not yet been concreted, since from the use of the fixing independent of the lifting device, for example in the form of a latch, i.e. the fixing of the climbing rail and climbing lifting rail to one another independently of the lifting device, no vertical loads have to be dissipated in the climbing shoe, which is anchored in the fresh concrete section, during the shuttering process. Closing the pawl diverts the vertical loads into a climbing shoe which is arranged below the climbing shoe of the fresh concrete section and is located in a fully hardened concrete section. This enables the formwork for the next concreting section to be set up as early as possible.

The arrangement according to the invention therefore makes it possible to temporarily hang the climbing rail in a climbing shoe of a concrete section that has not yet fully hardened and then to hang the climbing lifting rail in another climbing shoe of an already fully hardened concrete section that is arranged counter to the climbing direction, for example arranged below this climbing shoe in the case of a multi-storey structure to connect the climbing rail to the climbing lifting rail by means of the reversibly detachable fixation in such a way that the lifting device is relieved and the shuttering can take place in this fixed state.

Advantageously, the climbing rail and the climbing lifting rail are coupled to one another via the fixing means so that they can be fixed manually or automatically. Manual fixation is simple, inexpensive and requires less maintenance than automatic fixation, which may be technically more complex. On the other hand, automatic fixation excludes sources of human error and does not tie up valuable working time.

In one embodiment, the fixing means is designed as a snap-in or snap-in connection and comprises at least one snap-in/snap-in element and at least one holding element for holding the at least one snap-in/snap-in element. In particular, the fixing means can comprise either the at least one latching/snapping element and a multiplicity of holding elements or a multiplicity of latching/snapping elements and the at least one holding element for holding the at least one latching/snapping element of the multiplicity of latching/snapping elements. Snap-in or snap-in connections as fixing means are simple in design, inexpensive, low-maintenance and reliable.

In particular when the latching/snapping element is designed as a movable element, which is designed in particular to be pivotable, foldable or displaceable, in the form of a pawl, in particular a latch or fixing pawl, a latch, in particular a latching lug, a bolt, in particular a latching bolt, or a slide , the result is a simple and therefore reliable and low-maintenance fixing agent.

The holding elements in the form of fixing recesses for engagement with the at least one locking/snapping element fixed to the climbing rail can be introduced one after the other into the climbing lifting rail, or holding knobs can be applied, for example welded, to the climbing lifting rail. This results in a compact and cost-effective solution for the fixing means.

Advantageously, the climbing rail can have the fixing recesses on at least one side in such a way that the climbing rail is in the form of a profile with a hanging contour, in particular with teeth, or, in particular if only one locking/snapping element is fixed to the climbing rail, the climbing rail has the fixing recesses in the form of completely bordered holes, also called ears, which are, for example, quadrangular, in particular rectangular or square. The climbing lifting rail is then not only used as an alternative to the climbing rail for hanging into and/or unhooking from a climbing shoe, but also to accommodate the fixing recesses as part of the fixing means. In this case, the fixing recesses can be introduced in one operation with the introduction of the contour for hanging in and/or unhinging from a climbing shoe, which reduces the production costs compared to multi-stage processing and the material expenditure compared to separate elements for the climbing lifting rail and the fixing cutouts. Instead of the climbing lifting rail, the fixing recesses can also be provided in the climbing rail, for example in the form of teeth or holes.

If a fixed in or on the climbing rail locking / snap element in the form of fixing pawl for engaging in at least one fixing recess in the Climbing lifting rail is formed, resulting in a simple, low-maintenance and reliable embodiment for the fixative.

The fixing pawl can be rotatably connected to the climbing rail and, in the connected state, can be arranged on the climbing rail in such a way that a fixing lug of the fixing pawl, for example due to gravity, spring force, electrostatic force, magnetic force and/or electromagnetic force, can slide into the at least one fixing recess for Fixation of the climbing lifting rail with respect to the climbing rail, ie the fixing of the climbing lifting rail on the climbing rail, can intervene when the fixing recess is at the level of the fixing lug. In an embodiment using gravity, spring force and/or magnetic force, the climbing lifting rail can be automatically fixed or locked relative to the climbing rail without the introduction of further energy, for example from an external power source or a hydraulic unit.

The fixing pawl can be rotatably connected to the climbing rail in such a way that the fixing lug of the fixing pawl rests against an end face of the climbing lifting rail facing the fixing lug when the fixing recess is above or below, ie not at the level of, the fixing lug. This ensures that the fixing lug of the climbing rail can engage in the fixing recess of the climbing lifting rail when the fixing recess is at the level of the fixing lug. The attachment of the fixing lug to the front side of the climbing lifting rail facing the fixing lug can be done manually or by motor.

If a slot is provided in the fixing pawl, which has a vertical orientation in relation to the climbing rail when the climbing lifting rail is fixed with the fixing means, a pin fixed to the climbing rail, for example in the form of a screw, can run through the slot in such a way that the Fixing pawl is coupled translationally and / or rotationally to the climbing rail. This results in a very simple and yet fully functional coupling of the fixing pawl to the climbing rail.

In the fixed state, in one embodiment of the invention, a stop fixed to the climbing rail is arranged above the fixing lug between the fixing pawl and the climbing lifting rail in such a way that when an underside of the fixing lug rests on a fixing underside facing the underside of the fixing recess engaged with the fixing pawl Fixing pawl is canted with respect to a stop underside of the stop and the underside of the fixing recess facing the underside. This results in a fixing means with a reliable fixing or locking of the climbing rail relative to the climbing rail.

In a state of the climbing lifting rail that is not fixed with the fixing means with respect to the climbing rail, in which the fixing lug protrudes from a front side of the climbing lifting rail facing the fixing lug, a contact element can be provided on the climbing rail below the pin in such a way that when the fixing pawl is positioned with the pin in the fixing pawl rests against the contact element in an upper area of the elongated hole in order to protrude from the end face of the climbing lifting rail facing the fixing lug. In this open position, the fixing pawl can remain in a defined manner before the fixing lug of the fixing pawl rests against an end face of the climbing lifting rail that faces the fixing lug in the applied position.

A fixing flange which is fixed to the climbing rail and comprises the pin and/or the stop and/or the contact element can advantageously be arranged between the fixing pawl and the climbing rail. In this way, a climbing rail can be expanded and retrofitted with the fixing means in a simple and cost-effective manner without the fixing means being self-sufficient in relation to the lifting device and independent of a fixing of the lifting device. The fixing flange on the one hand and the pin and/or stop and/or the contact element on the other hand can be present in an integral form or in a form that is connected to one another.

If a maximum distance from each other in a longitudinal direction of the climbing lift tickets arranged one behind the other fixing recesses corresponds to a maximum stroke length of the lifting device, over part of the maximum stroke length or at maximum stroke length, i.e. fully extended lifting device, the fixation can be carried out independently of a fixation by the lifting device. Fixing the climbing lifting rail on the climbing rail according to the invention is therefore possible in all operating states of the lifting device with regard to its lifting length and its lifting power.

A distance between adjacent fixing recesses from one another can essentially correspond to a distance between adjacent retaining elements in the form of retaining recesses introduced into the climbing lifting rail one behind the other in one/the longitudinal direction of the climbing lifting rail or retaining knobs applied to the climbing lifting rail for engaging with at least one locking/snapping element of the climbing shoe. This simplifies the manufacture of such a climbing lifting rail.

The invention also includes a rail-guided climbing system which comprises the arrangement according to the invention of a climbing rail and a climbing lifting rail, the overall length of the at least one climbing rail being sufficient to guide the climbing rail from at least two climbing shoes which are at a predetermined distance, for example one storey height, are spaced apart. The climbing system can be held by one of the at least two climbing shoes and the climbing shoes can be arranged in the climbing direction in such a way that the climbing shoe, into which the climbing rail was hung before the lifting device was extended by the lifting device, in concrete that has not yet fully hardened is anchored and the climbing shoe, in which the climbing lifting rail is hung when being fixed to the climbing rail independently of a fixing by the lifting device, is arranged in a previously completed concreting section with fully hardened concrete. The climbing system can include a scaffolding unit and/or protective wall into which the at least one climbing rail is integrated or to which the at least one climbing rail is attached.

A method for climbing a rail-guided climbing system, which can be used in particular as a climbing formwork, climbing scaffold, climbing protection panel and/or climbing work platform, with the inventive arrangement of a climbing rail and a climbing lifting rail also belongs to the invention. The procedure includes the following steps:

• Applying the fixing pawl, which is rotatably connected to the climbing rail, to a front side of the climbing lifting rail facing the fixing lug, with the fixing recess being located above or below, i.e. not at the level of, the fixing lug,
• Extending the lifting device when the climbing rail is suspended, the climbing lifting rail being displaced relative to the climbing rail in the opposite direction to the climbing direction until the climbing lifting rail is suspended,
• Continuation of the extension movement of the lifting device, with further displacement of the climbing lifting rail against the climbing direction being prevented by the completed hooking of the climbing lifting rail and the climbing rail being unhooked and shifted in the climbing direction relative to the climbing lifting rail until the fixing lug of the fixing pawl is in the at least one fixing recess for fixing the climbing lifting rail engages in relation to the climbing rail, the fixing recess being located at the level of the fixing lug, and
• Retraction of the lifting device, the climbing rail being displaced counter to the climbing direction relative to the climbing lifting rail until the fixing lug of the fixing pawl engaged in the at least one fixing recess picks up a load of the climbing system hanging on the climbing rail.

After applying the fixing pawl, which is rotatably connected to the climbing rail, to a front side of the climbing lifting rail that faces the fixing lug, the climbing lifting rail is hung in at least one climbing shoe. Thereafter, the lifting device is extended in order to hang the climbing lifting rail, which leads to the climbing rail being unhinged. The climbing lifting rail is then fixed in a reversibly detachable manner and independently of fixing by the lifting device on the climbing rail by engaging the fixing lug of the fixing pawl in the at least one fixing recess for fixing the climbing lifting rail with respect to the climbing rail. By retracting the lifting device, the vertical load of the climbing system is diverted via the climbing rail, the fixing pawl, the fixing recess, the climbing lifting rail and the climbing shoe into the concrete section in which the climbing shoe is anchored. Then you can immediately start with the shuttering.

The climbing shoe into which the climbing rail was hooked before the climbing lifting rail was hooked in by extending the lifting device, whereby the climbing rail was hung out can be located further in the climbing direction than the climbing shoe into which the climbing lifting rail is hung when the lifting device is extended. The climbing shoe into which the climbing rail was hung before the climbing lifting rail was hung by extending the lifting device can be anchored in a concrete that has not yet fully hardened and the climbing shoe into which the climbing lifting rail is fixed independently of a fixation by the lifting device on the Climbing rail is hooked in can be arranged in a previously completed concreting section with fully hardened concrete. Immediately after climbing over the last completed concreting section that has not yet fully hardened, which is indicated by the hanging of the climbing rail into the climbing shoe of this concreting section, the next concreting section to be completed can be shuttered with the climbing system, because during shuttering the vertical load of the climbing system is not in this Climbing shoe, but is derived in the relative to this climbing shoe against the climbing direction arranged next climbing shoe, which is anchored in an already fully cured concreting section.

In a further method for climbing a rail-guided climbing system, which can be used in particular as a climbing formwork, climbing scaffold, climbing protection panel and/or climbing work platform, with the arrangement of a climbing rail and a climbing lifting rail according to the invention, the following steps are carried out:

• Extending the lifting device when the climbing rail is suspended, the climbing lifting rail being displaced relative to the climbing rail in the opposite direction to the climbing direction until the climbing lifting rail is suspended,
• Continuation of the extension movement of the lifting device, with further displacement of the climbing lifting rail against the climbing direction being prevented by the completed hanging of the climbing lifting rail and the climbing rail being unhooked and displaced relative to the climbing lifting rail in the climbing direction, for example by at least one hanging distance of the climbing rail and additionally a climbing shoe travel path,
• Retraction of the lifting device, with the climbing rail being displaced in the opposite direction to the climbing direction relative to the climbing lifting rail, until the climbing rail is hooked in, displaced in the climbing direction, for example by at least the one hanging distance,
• Continuation of the retraction movement of the lifting device, with further displacement of the climbing rail against the climbing direction being prevented by the completed hanging of the climbing rail and the climbing lifting rail being unhooked and shifted in the climbing direction, for example by at least the one hanging distance of the climbing rail relative to the climbing rail,
• Applying the fixing pawl, which is rotatably connected to the climbing rail, to a front side of the climbing lifting rail facing the fixing lug, with the fixing recess being located above or below, i.e. not at the level of, the fixing lug,
• Extending the lifting device, further displacement of the climbing lifting rail counter to the climbing direction after the climbing lifting rail has been hooked in is prevented and the climbing rail is unhooked and displaced relative to the climbing lifting rail in the climbing direction until the fixing lug of the fixing pawl, for example due to gravity, into the at least one Fixing recess for fixing the climbing lifting rail with respect to the climbing rail engages, the fixing recess being at the level of the fixing lug, and
• Retraction of the lifting device, the climbing rail being displaced counter to the climbing direction relative to the climbing lifting rail until the fixing lug of the fixing pawl engaged in the at least one fixing recess picks up a load of the climbing system hanging on the climbing rail.

This method results in the same advantages and effects as in the previously described method, with the climbing rail also being fixed independently of the lifting device and independently of the lifting device on the climbing lifting rail, the climbing rail is shifted, for example, by at least one mounting distance of the climbing rail in the climbing direction.

The process steps according to the invention are preferably defined as a cycle and the cycle is run through until the scaffolding unit and/or protective wall has reached one or more further storeys of the building or a concrete section of the building to be concreted.

In Figure 1a a rail-guided climbing system 10 with a scaffolding unit 11 for climbing on a building 1 is shown in a three-dimensional external view. The structure 1 comprises several storeys with outer walls 40, 44, 48, 52, the storeys comprising floor slabs 42, 46, 50 and 54 and being arranged one above the other in the Y direction, which corresponds to a climbing direction of the climbing system 10. On the outer walls 40, 44, 48, 52 of the building 1, climbing shoes, for example the climbing shoe 32, are fastened one above the other in the Y direction and next to one another in the Z direction for each outer wall. The framework unit 11 of the climbing system 10 is suspended in at least one climbing shoe via an arrangement of a climbing rail and a climbing lifting rail, both of which are aligned in the Y direction, and can be displaced in the Y direction and in the negative Y direction. The arrangement occurs twice in the climbing system 10 such that both arrangements are in the Z direction next to each other and parallel to each other and the scaffold unit 11 in at least one climbing shoe is attached to each arrangement of climbing rail and climbing lifting rail.

The scaffolding unit 11 comprises a formwork platform 12 with a formwork 13, which can be moved together in the horizontal direction, i.e. the X direction and/or the negative X direction, toward the building 1 and/or away from the building 1, in order to create a concrete section For example, to complete a floor of the building 1. The formwork 13 is fastened to horizontal supports, which in turn are fastened to vertical supports 13' of the formwork 13. A railing 13" is fastened to the vertical supports 13' as part of the formwork platform 12 in order to be able to pour liquid concrete behind the formwork 13 in the negative X-direction to complete the concrete section to be concreted, and to be able to secure it against falling from the formwork platform 12 be.

A working platform 16 is arranged below the formwork platform 12 and 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 10 can be arranged on the working platform. The lifting device 26 is located on a trailing platform 22 which is arranged below the working platform 16 and is fixed to the working platform 16. The scaffolding unit 11 therefore comprises, in the case of the Figure 1a Climbing system 10 shown includes formwork platform 12, working platform 16 and trailing platform 22, with a climbing rail that can be inserted into the climbing shoes in the opposite direction to the climbing direction and detachable from the climbing shoes in the climbing direction, being integrated into scaffolding unit 11 or attached to scaffolding unit 11. The trailing platform 22 is used, among other things, for attaching and removing the climbing shoes, for example the climbing shoe 32 , which are stationarily arranged on the building 1 and serve to guide and support the climbing rail which carries the scaffolding unit 11 . In Figure 1a two climbing rails, each running in the Y direction, are arranged parallel to one another in the Z direction on the scaffolding unit 11 .

In Figure 1b For example, the climbing shoe 32 attached to the outer wall 40 is shown in cross-section in the X/Z plane along with a climbing rail 18 and a climbing lifting rail 24 . The climbing shoe 32 is inserted into a recess in the outer wall 40 in the negative X-direction and fixed to the outer wall 40 . In the Z-direction, the climbing shoe 32 has opposite legs 32' facing one another for engaging in the climbing rail 18 and a climbing pawl 32'' for engaging in the climbing lifting rail 24. The climbing lifting rail 24 has an I-shaped cross section, also known as a double T -shaped cross-section. The climbing lifting rail 24 is arranged in the climbing rail 18 between two U-shaped elements of the climbing rail 18, with the side of the climbing lifting rail 24 facing the outer wall 40 being able to engage in the climbing pawl 32", which in Figure 1b can be seen because, in addition to the cross section of the climbing rail 18 and the climbing lifting rail 24, a top view of the climbing shoe 32 is shown.

The climbing pawl 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 40. In addition, the climbing shoe 32 has the two legs 32', the lugs of which rest on the sections of the climbing rail 18 facing the outer wall 40 The legs 32" can each be pivoted about the vertical axis, which runs in the Y direction, and can be fixed in their position with locking pins. Other legs are possible that cannot be pivoted and/or used without a locking pin. The climbing pawl 32" can engage in both the climbing lifting rail 24 and the climbing rail 18 in order to enable both the climbing lifting rail 24 and the climbing rail 18 to be hung in the climbing shoe 32. However, designs of climbing shoes are also conceivable in which different climbing pawls are present in order to be able to attach and detach either the climbing rail 18 or the climbing lifting rail 24.

In the top view of Figure 1b An upper end 28 of a lifting device 26 can be seen, which is arranged between the two U-shaped elements of the climbing rail 18 and is connected to these elements and consequently to the climbing rail 18, for example via the in Fig. 1b shown oriented in the Z direction screw connection. The climbing rail 18 is guided by the climbing shoe 32, with the climbing rail 18 and the climbing lifting rail 24 each being able to be hooked into at least the climbing shoe 32 in the opposite direction to the climbing direction, i.e. the negative Y direction, and in the climbing direction, i.e. the Y direction are detachable from the climbing shoe 32 and slidable relative to this climbing shoe.

In Figure 2a is that in Fig. 1a Climbing system 10 shown shown in a side view. The scaffolding unit 11 of the climbing system 10 is attached to the climbing rail 18 with the shuttering platform 12, the working platform 16 and the trailing platform 22. It is also possible for the platforms 12, 16 and 22 and the climbing rail 18 to be an integral part of the scaffolding unit 11. The climbing rail 18 is guided by climbing shoes 32, 34 and 36 and is always suspended in at least one of the climbing shoes 32, 34, 36. The climbing shoe 38 in the outer wall 52 with the floor slab 54 extending in the negative X-direction serves to guide and suspend the rail 18 when the next outer wall in the Y-direction above the outer wall 52 is to be concreted. Since the outer wall 52 with the floor slab 54 is concreted last, a load capacity of the outer wall 52 by hanging the climbing system 10 in the climbing shoe 38 is lower than a load capacity of the outer wall 48, which is arranged below the outer wall 52 in the negative Y-direction and earlier than the outer wall 52 was concreted. It is therefore possible that the scaffolding unit 11, whose vertical load is dissipated into the building 1 by the climbing rail 18, may not be suspended in the climbing shoe 38 of the outer wall 52 as long as the concrete in this outer wall has not hardened sufficiently. Instead, the climbing system 10 should be suspended in at least one of the climbing shoes 32, 34 and/or 36, since the outer walls 40, 44 and 48 with the floor slabs 42, 46 and 50 have already hardened sufficiently to be able to support the climbing system 10. The climbing lifting rail 24 at the level of the climbing shoe 32 and the climbing shoe 34 can be displaced relative to the climbing rail 18 and is guided by the climbing rail 18, with the climbing lifting rail 24, like the climbing rail 18, in the opposite direction to the climbing direction, i.e. in the negative Y direction, in each of the Climbing shoes 32, 34, 36, 38 can be hooked in and in the climbing direction, ie in the positive Y direction, from each of the climbing shoes 32, 34, 36, 38 can be unhooked and slidable relative to each of these climbing shoes.

The climbing system 10 also includes the lifting device 26 which is fixed at one end to the climbing rail 18 with its upper end 28 in the Y direction and at the other end to the climbing lifting rail 24 with a lower end in the negative Y direction of the lifting device 26 . The climbing rail 18 and climbing lifting rail 24 are therefore fixed to one another by the lifting device 26 and can be displaced relative to one another by means of the lifting device 26 in order to bring about a climbing movement in the Y direction. The hydraulic unit 6 is arranged on the trailing platform in order to supply the lifting device 26 with energy for operating the lifting device 26 . As already described, the hydraulic unit 6 can also be used to shift the casing 13, which is attached to the vertical supports 13' for shifting in the negative X-direction and/or in the X-direction. The railing 13" attached to the vertical supports 13' is used to secure a worker who fills with concrete a cavity of a concrete section to be concreted, for example a next outer wall of the building 1 to be concreted.

In Figure 2b is a section A of Figure 2a shown enlarged. Climbing rail 18 has support bolts 19', which can each be hooked into one of the climbing shoes 32, 34, 36 and removed from each of these climbing shoes, in the Y direction, with three bores 19 between adjacent support bolts 19' of climbing rail 18 in the Climbing rail 19 are arranged. The support bolts 19' are spaced apart from one another by a suspension distance 20 in the Y direction, with the lifting device 26 having a stroke which is able to cover the suspension distance 20 and also a climbing shoe travel path in order to offset the climbing rail by a suspension distance 20 into a the climbing shoes 32, 34, 36 to be able to hang. The climbing lifting rail 24 can be displaced relative to the climbing rail 18 and is guided by the climbing rail 18 by at least one guide shoe 19" or another type of guide. In addition, the climbing lifting rail 24 is, for example in an end section of the climbing lifting rail in the negative Y direction, via the lower end 27 of the lifting device 26 with the upper end 28 of the lifting device 26, for example via a piston and a lifting cylinder, connected to the climbing rail 18.

In addition, a fixing means 7 is provided in order to fix the climbing rail 18 and the climbing lifting rail 24 to one another in a reversibly detachable manner, independently of the fixing to one another by the lifting device 26 . The fixing means 7 is in a closed position such that the climbing rail 18 is reversibly and detachably fixed to the climbing lifting rail 24 . The two rails are fixed to one another independently of any further fixing of the two rails to one another by the lifting device 26. In this respect, the fixing means 7 is able to fix the climbing rail 18 and the climbing lifting rail 24 to one another independently, i.e. as if the lifting device 26 would not exist.

In Figure 2c is the in Figure 2b Section A shown is shown in a three-dimensional external view. The support bolts 19', which are spaced apart from one another in the Y direction by the hanging distance 20 of the climbing rail 18, allow the climbing rail 18 to be hooked into each of the climbing shoes 32, 34, 36, with the lifting device 26 having a stroke length 3 by the hanging distance 20 and additionally to sweep over the climbing shoe crossing path if the climbing rail is to be hung in one of the climbing shoes 32, 34, 36 offset in the Y direction by the hanging distance 20. The climbing shoe crossing path is to be swept over by the support bolt 19' at the height of one of the climbing shoes 32, 34, 36, ie horizontally in the X direction, in the Y direction in order to enable a subsequent hanging of the climbing rail 18 with a movement in the negative Y direction. to reach direction. Sweeping over the climbing shoe travel path therefore puts the climbing shoe in an operating state in which the climbing rail 18 can be hooked in during a movement in the direction opposite to the climbing direction, ie the negative Y-direction, after this movement has ended.

The climbing lifting rail 24 is displaceably guided on the climbing rail 18 and the climbing lifting rail 24 is fixed to the climbing rail 18 via the lifting device 26 .

In addition, the fixing means 7, which is arranged, for example, above the lifting device 26 in the Y-direction, is present in order to reversibly fix the climbing rail 18 and the climbing rail 24 to one another independently of the fixing to one another by the lifting device. The fixing means 7 is in the closed position G in such a way that the climbing lifting rail 24 is fixed to the climbing rail 18 independently of an operating state of the lifting device 26 . If the climbing system 10 is attached to the outer wall of the building 1 via the climbing rail 18 and the climbing lifting rail 24 by introducing a vertical load of the climbing system 10 into at least one of the climbing shoes 32, 34, 36, the lifting device 26 can be deactivated or switched off. in order to avoid compressive and/or tensile loading of the lifting device 26 and to save energy from the hydraulic unit 6 for supplying the lifting device 26 when the climbing system 10 is connected via the climbing lifting rail 24 to one of the climbing shoes 32, 34, 36 for introducing the vertical load of the climbing system 10 is connected to the building 1.

In Figure 3a is that in Figure 2a shown rail-guided climbing system 10 with the arrangement of the climbing rail 18 and the climbing lifting rail 24 and the fixing means 7 in an open position O shown in a side view. The framework unit 11 of the climbing system 10 is fastened to the structure 1 in such a way that the climbing lifting rail 24 is suspended in the climbing shoe 34 in an upper section of the climbing lifting rail in the Y direction. The scaffolding unit 10 attached to the climbing rail 18 or present integrally with the climbing rail 18 is not fixed to the climbing lifting rail 24 via the fixing 7, since the fixing 7 is in the open position O, in which the climbing lifting rail is fixed to the climbing rail not available. Instead, the vertical load of the scaffolding unit 10 acting on the climbing shoe 34 and introduced into this climbing shoe via the climbing lifting rail 24, for example from an upper section of the climbing lifting rail in the Y direction to a lower section of the climbing lifting rail in the negative Y direction, to the lower Out end 27 of the lifting device 7, as shown by the arrow F1. The vertical load of the scaffolding unit 11 is guided from the lower end 27 of the lifting device 26 to the upper end 28 of the lifting device 26 that is connected to the climbing rail 18 . At the location of the upper end 28 of the lifting device i.e. the vertical load of the scaffolding unit 11 of the climbing system 10 into the lifting device 26, then into its lower end 27 and from there via a lower section of the climbing lifting rail 24 to an upper section of the climbing lifting rail 24 and from there into the climbing shoe 34 and from there into the structure 1 derived.

In Figure 3b the arrangement of climbing rail 18 and climbing lifting rail 24 with the fixing means 7 in the open position O is shown enlarged in a three-dimensional external view. The climbing lifting rail 24 is guided on the climbing rail 18 by means of two guide shoes 19", the first guide shoe 19" being located in an upper section of the climbing lifting rail 24 and the second guide shoe 19" being arranged in a lower section of the climbing lifting rail 24. The lifting device 26 is extended by the stroke length 3, with a further extension of the lifting device in the Y-direction leading to the climbing lifting rail 24 being lifted out of the guide by the guide shoe 19" on the lower end section of the climbing lifting rail 24 in the Y-direction. The climbing lifting rail 24 has fixing recesses 24', into which a fixing pawl 8 of the fixing means 7 can engage. At a given point in time, when the fixing pawl 8 is at the level of one of the fixing recesses 24 ′, ie horizontally in the Y direction, the fixing pawl can engage in the fixing recess 24 ′ at the level of the fixing pawl 8 . The fixing pawl is not latched into any of the fixing recesses 24', so that the fixing means 7 is in the open position O. In addition to the fixing recesses 24 ′ for engaging in the fixing pawl 8 of the fixing means 7 , the climbing lifting rail has holding recesses 61 which serve to hang the climbing lifting rail 24 in one of the climbing shoes 32 , 34 , 36 . Both the fixing recesses 24' and the holding recesses 61 are spaced apart from one another at essentially equal distances and are each aligned in the climbing direction, ie the Y direction. The fixing pawl 8 is rotatably mounted on a fixing flange 9 about an axis of rotation 9 ′, which can be formed, for example, by a screw of a screw connection and is aligned in the Z direction. The fixing pawl 8 is therefore rotatably connected via the axis of rotation 9 ′ to the fixing flange 9 which is fixed to the climbing rail 18 , for example by using a further screw connection through the bore 19 in the climbing rail 18 . A distance from adjacent to each other Retaining recesses 61 can correspond to a spacing of mutually adjacent fixing recesses 24'. Different distances between adjacent holding recesses 61 compared to a distance between adjacent fixing recesses 24' are possible.

In Figure 4a is that in Figure 2a shown rail-guided climbing system 10 with the arrangement of the climbing rail 18 and the climbing lifting rail 24 and the fixing means 7 in the closed position G shown in a side view. In contrast to the state of the fixing means 7 as shown in Figure 3a the fixing means 7 is reversibly releasably closed in such a way that the climbing lifting rail 24 is fixed to the climbing rail 18 and is therefore not movable relative to the climbing rail 18 in the climbing direction and in the opposite direction to the climbing direction. The vertical load of the scaffolding unit 11 of the climbing system 10, which is dissipated via the climbing shoe 34 into the outer wall 44 of the building 1, is transferred from an upper section of the climbing lifting rail 24 in the Y direction, via which the climbing lifting rail 24 is connected to the climbing shoe 34 and into the Climbing shoe 34 is hung, guided approximately in a middle section of the climbing lifting rail 24, where a fixing recess 24' is present, into which the fixing pawl 8 of the fixing means 7 engages. The vertical load is therefore introduced from the fixing recess 24 ′ into the fixing pawl 8 of the fixing means 7 and from there via the axis of rotation 9 ′ into the fixing flange 9 which is fixed to the climbing rail 18 . The vertical load of the scaffolding unit 11 of the climbing system 10 applied to the climbing rail 18 is therefore transferred to the fixing flange 9 and from there via the axis of rotation 9' to the fixing pawl 8 and from there to the fixing recess 24' in the climbing lifting rail 24 and from there to the one holding recess 61 in the climbing lifting rail 24, which is hung in the climbing shoe 34 in order to derive the vertical load via the climbing shoe 34 into the outer wall 44 of the building 1. Fixing the climbing rail on the climbing lifting rail allows the lifting device 26 to be switched off, which is connected to both the climbing lifting rail 24 and the climbing rail 18, but when switched off does not allow the vertical load of the scaffolding unit 11 to be diverted from the climbing rail to the climbing lifting rail. Instead, the fixing of the climbing lifting rail and the climbing rail takes over one another that fixing means 7 in the closed position G, so that the Lifting device 26 can be switched off, is not subject to tensile and / or pressure loads and the hydraulic unit 6 does not have to provide energy to maintain the operation of the lifting device 26.

In Figure 4b is the arrangement of climbing rail 18, climbing lifting rail 24 and fixing means 7 according to Figure 4a shown enlarged in a three-dimensional external view. The climbing lifting rail 24 is in accordance with in Figure 3b shown state of the climbing lifting rail 24 by two guide shoes 19" and fixed via one of the fixing recesses 24' and a fixing pawl 8 of the fixing means 7 engaging in the fixing recess 24' on the climbing rail 18. The fixing pawl 8 can be rotated via the axis of rotation 9' relative to the Fixing flange 9 is mounted, which is connected to the climbing rail 18, for example via the bore 9 and a screw connection in the Z direction. which, like the holding recesses 61, lie next to one another in the Y direction, i.e. the climbing direction is greater than the stroke length 3 of the lifting device 26. The distance 60 between mutually adjacent holding recesses 61 corresponds to the distance 24A between mutually adjacent fixing recesses 24'. Due to the fixing of the climbing lifting rail 24 to the climbing rail 18 by means of the fixing means 7, which is in the closed position G and is therefore closed or locked, further or additional fixing of the two rails to one another by the lifting device 26 is not necessary. Instead, the lifting device 26 can be switched off and, without being able to divert a vertical load applied to the climbing rail 18 via the lifting device 26 into the climbing lifting rail 24, only be connected to the climbing rail 18 with the upper end 28 and with the lifting rail 24 with the lower end 27 .

In Figure 5a is the same fixing means 7 in different operating states in combination with the climbing lifting rail 24 in the open position O, laid-down position A and closed position G shown in side view. The climbing lifting rail 24 with the fixing recesses 24' is therefore not to be regarded as a continuous rail in the Y direction, but rather the same fixing means 7 is located on the same climbing lifting rail 24, with the fixing means 7 in the X direction being at different heights relative to the Climbing lifting rail 24 is located. The fixing means 7 therefore has the same elements in each of the three operating states, so that although there are several fixing recesses 24', there is only one fixing lug 8', for example, which engages in one of the fixing recesses 24' in the closed position. This is illustrated by horizontal lines in the X direction, which separate the illustrated operating states of the same fixing means 7 from one another. Correspondingly, in Figure 5b the same fixing means 7 in the open position O, applied position A and closed position G shown spatially in cross section, as in FIG Figure 5a the same fixing means 7 is shown in the different operating states on the same climbing lifting rail 24 (see horizontal lines for delimiting the illustrated operating states from one another).

In the upper area of each Figure 5a and 5b the fixing means 7 is shown in the open position O as the operating state. The fixing means 7 comprises the fixing pawl 8 with a fixing lug 8', the fixing pawl 8 having a slot 8" which, when the climbing lifting rail 24 is fixed with the fixing means 7, i.e. in the closed position G, which is in the lower area of the Figure 5a and the Figure 5b shown, has a vertical orientation in the Y-direction. Arranged between the fixing pawl 8 and the climbing rail 18 (not shown) is a fixing flange 9 which is fixed to the climbing rail and comprises a pin 9' and a stop 9'' as well as a bearing element 9‴. The pin 9' is designed in the form of a screw, which runs through the slot 8" and is fixed to the climbing rail in such a way that the fixing pawl 8 is coupled to the climbing rail 18 in translation and rotation via the fixing flange 9. In the open position O, i.e. the unfixed state of the climbing lifting rail 24 with respect to the climbing rail 18, the fixing lug 8' protrudes from an end face 24" of the climbing lifting rail 24 facing the fixing lug 8', with below the pin 9', i.e. in the negative Y-direction, the contact element 9 ‴ on the fixing flange 9, which in turn is attached to the climbing rail 18, such it is provided that when the fixing pawl 8 is positioned with the pin 9' in an upper region of the elongated hole 8", the fixing pawl 8 rests against the contact element 9‴ in order to protrude from the end face 24" of the climbing lifting rail 24 facing the fixing lug 8'. Arranged between the fixing pawl 8 and the climbing rail 18 is the fixing flange 9 fixed to the climbing rail 18, which includes the pin 9', the stop 9'' and the contact element 9‴. In the open position O there is a contact lug 8‴ of the fixing pawl 8 below the upper point of the contact element 9‴ in the Y-direction in such a way that, without moving the fixing pawl 8 in the Y-direction, the open position O of the fixing means 7 cannot be moved into the applied position A by moving the fixing pawl 8 into the negative X-direction can be transferred.

In the middle area of each of the Figures 5a and 5b the fixing means 7 shown in the open position in the upper region of these figures is shown in the applied position A. The fixing pawl 8 is connected to the climbing rail 18 via the axis of rotation 9' in the embodiment of a screw connection in such a way that the fixing lug 8' of the fixing pawl 8 rests against the end face 24'' of the climbing lifting rail 24 facing the fixing lug 8' when the fixing recess 24' above or below, ie not at the level in the X-direction, the fixing lug 8 'is, as in the middle section of the Figures 5a and 5b is shown in each case. Although in the open position O the fixing lug 8' is at the level of the fixing recess 24', the fixing lug 8' does not bear against the climbing lifting rail 24 because the contact element 9‴ attached to the fixing flange 9 is arranged in relation to the fixing pawl 8 that a movement of the fixing lug 8 'and thus the fixing pawl 8 in the direction of the climbing lifting rail 24 in the negative X-direction due to gravity is prevented by the attachment of the fixing pawl 8 to the contact element 9‴. This is not the case in the applied position A, because the fixing pawl 8 was moved in the Y direction, guided through the slot 8" and the axis of rotation 9', in order to lift the fixing pawl 8 over the contact element 9‴ and into the negative X direction to the end face 24" of the climbing lifting rail 24 facing the fixing lug 8'. The contact lug 8‴ of the fixing pawl 8 is in the applied position A below an upper point of the contact element 9‴ in the Y direction in such a way that without moving the fixing pawl 8 in the Y-direction, the fixing pawl 8 cannot leave the applied position to return to the open position.

In the bottom of each of the Figures 5a and 5b the fixing means 7 shown in the middle section in the applied position A and in the upper section in the open position O is shown in the closed position G. The fixing pawl 8 is rotatably connected to the climbing rail 18 via the fixing flange 9 and is arranged in such a way that the fixing lug 8' of the fixing pawl 8 engages in the fixing recess 24' for fixing the climbing lifting rail 24 with respect to the climbing rail 18 due to the force of gravity, with the fixing recess 24 'At the height of the fixing lug 8', ie in the horizontal or in the X-direction at the same height as the fixing pawl 8'. In the fixed state of the climbing rail 18 relative to the climbing rail 24, i.e. in the closed position G as a further operating state of the fixing means 7, above the fixing lug 8', i.e. in the Y direction, between the fixing pawl 8 and the climbing lifting rail 24 stop 9" fixed to the climbing rail via the fixing flange 19. The stop 9" is arranged in such a way that when an underside of the fixing lug 8' rests on a fixing underside 24‴ facing the underside of the fixing recess 24' that engages with the fixing pawl 8, the fixing pawl 8 is canted with respect to a stop underside of the stop 9" and the fixing underside 24‴ of the fixing recess 24' facing the underside. In the closed position G, the contact lug 8‴ of the fixing pawl 8 is no longer on the contact element 9"', but on the Fixing lug 8' facing the end face 24" of the climbing lifting rail 24. The elongated hole 8" is vertical, i.e. in the Y direction, thus aligned parallel to an alignment of the climbing lifting rail 24, with a fixing pawl 8"" at the lower end of the fixing pawl 8 in the negative Y-direction on a side facing away from the climbing lifting rail 24 of the contact element 9‴.

Since the fixing underside 24‴ of the fixing recess 24′ rests against the underside of the fixing lug 8′, the fixing pawl 8 and thus the climbing rail 18 cannot be displaced in the negative Y-direction in relation to the climbing lifting rail 24, i.e. counter to the climbing direction. As long as, for example due to the vertical load applied to the climbing rail 18, a force in the negative Y-direction, ie in the Climbing direction opposite direction on which the fixing pawl 8 acts, due to the contact of the underside of the fixing lug 8' on the fixing underside 24‴ of the fixing recess 24', the fixing pawl 8 and thus the climbing rail 18 and consequently the scaffolding unit 11 cannot move in the direction opposite to the climbing direction, i.e. the negative Y-direction. When the fixing pawl 8 is raised in the climbing direction, i.e. the Y direction, by raising the climbing rail 18 due, for example, to an extension movement of the lifting device 26, the fixing lug 8' together with the stop 9" can be displaced in the climbing direction in such a way that when the fixing pawl tab 8 "" the fixing pawl 8 is rotated about the axis of rotation 9 ′ in the X direction in such a way that the fixing pawl 8 can be moved from the closed position G into the applied position A and/or into the open position O.

Both the contact element 9‴ and the axis of rotation 9′ are, as in Figure 5b can be seen in the lower section, each designed as a screw connection with cylindrical screws. Since the fixative 7 in each of the Figures 5a, 5b shown in cross section, the fixing flange 9 does not have an L-shape as in FIG Figure 5b shown, but a U-shaped form with an open U in the X-direction, as is the case, for example, in Figure 4b is shown. The screw connections of both the axis of rotation 9' and the contact element 9‴ are therefore each guided through bores in two opposite sides of the fixing flange 9 (see Figure 4b ). Since the fixing lug 8' automatically engages in the fixing recess 24' due to gravity when the fixing recess 24' is at the level of the fixing lug 8', i.e. at the same height as the fixing lug 8' in the X direction, this is the fixing means 7 to a semi-automatic manually operated fixing device. Other, manual or fully automatic, fixing means 7 are possible. That in the Figures 5a and 5b Fixing means 7 shown in each case has a mechanically simple structure, requires little maintenance, is inexpensive to produce and is reliable in such a way that it can be used efficiently for use in a climbing system. Due to the interaction of the fixing pawl nose 8‴ and the fixing pawl tab 8″″ with the contact element 9‴ with the guidance of the fixing pawl 8 through the axis of rotation 9′ and the elongated hole 8″, defined operating states in the open position, Applied position and closed position achieved, which serves the operational safety of the fixing means 7.

In the Figures 6a - 6k are climbing states of the in 1 Climbing system 10 shown with the fixing means 7 in the open position O for the Figures 6a - 6f , Moored position A in the Figures 6g - 6i and closed position G in the Figures 6j and 6k shown in side view. In Figure 6a the scaffolding unit 11 of the climbing system 10 is suspended in the climbing shoe 34 via the climbing rail 18. The elevator 26 is fully retracted and a stroke length 2 is zero. The fixing pawl 8 faces away from the climbing lifting rail 24, i.e. in the X-direction, opposite the fixing flange 9 in such a way that the fixing means 7 is in the open position O (see the upper sections of each of the Figures 5a, 5b ).

In Figure 6b the climbing lifting rail 24 is shifted in the negative Y-direction, ie in the direction opposite to the climbing direction, in such a way that the climbing lifting rail 24 is suspended in the climbing shoe 32 . In this operating state of the arrangement of climbing rail 18 and climbing lifting rail 24 , the scaffolding unit 11 is suspended via the climbing rail 18 in the climbing shoe 34 and additionally via the climbing lifting rail 24 in the climbing shoe 32 . The lifting device 26 is supplied with energy via the hydraulic unit 6 in such a way that the lifting device extends and a stroke length 3A which is greater than the stroke length 2 is present. A distance 3A' from the upper edge of the climbing rail 18 to the upper edge of the climbing lifting rail 24 is greater than the distance 2' in by the stroke length 3A Figure 6a the upper edge of the climbing rail 18 to the upper edge of the climbing lifting rail 24. A distance 3A" of the upper edge of the climbing rail 18 to the upper edge of the floor slab 50 is in Figure 6b equal to the distance 2" in Figure 6a because the climbing lifting rail 24 is only shifted in the direction opposite to the climbing direction, without changing the position of the climbing rail 18 relative to the floor slab 15 and thus to the building 1. The fixing means 7 with the fixing pawl 8 is still in the open position.

In Figure 6c the lifting device 26 moves further and, since the climbing lifting rail 24 is suspended in the climbing shoe 32, lifts the scaffolding unit 11 attached to the climbing rail 18 in the climbing direction, ie the Y direction. The stroke length 3b is therefore greater than the stroke length 3a in Figure 3b and the distance 3B" from the top edge of the climbing rail 18 to the top edge of the floor slab 50 is smaller than the corresponding distance 3A" according to FIG Figure 6b . Since the climbing rail 18 is displaced in the climbing direction relative to the climbing lifting rail 24 due to the lifting device 26, the distance 3B' between the top edge of the climbing rail 18 and the top edge of the climbing lifting rail 24 is greater than the corresponding distance 3A' in Figure 6b . The fixing means 7 is still in the open position.

In Figure 6d the scaffolding unit 11 is still hooked into the climbing shoe 32 by means of the climbing lifting rail 24, the stroke length 4 of the lifting device 26 being significantly greater than the stroke length 3B according to FIG Figure 6c is enlarged. Consequently, the distance 4' from the top of the climbing rail 18 to the top of the climbing lifting rail 24 is greater than the distance 3B' from the top of the climbing rail to the top of the climbing lifting rail according to the difference in stroke lengths 4 and 3B Figure 6c . The difference in stroke lengths 3B and 4 therefore results in the distance 4" from the top edge of the climbing rail 18 to the top edge of the floor slab 50 in contrast to the corresponding distance 3B" in Figure 6c is now zero. The fixing means 7 is still in the open position. In comparison of Figures 6c and 6d it becomes clear that the climbing rail is 18 in Figure 6d drive through the climbing shoe 36 in the Y-direction and has thus passed through the climbing shoe crossing path.

In Figure 6e the scaffolding unit 11 is lowered onto the climbing shoe 36 by retracting the cylinder of the lifting device 26 and the scaffolding unit 11 is thereby hooked into the climbing shoe 36 via the climbing rail 18 . The stroke length 3D is consequently smaller than the stroke length 4 of the lifting device 26 in Figure 6d and the upper edge of the climbing rail is arranged below the upper edge of the floor in such a way that the distance 3D" between the upper edge of the climbing rail 18 and the upper edge of the floor 50 corresponds approximately to the thickness of the floor 50. By driving over the climbing shoe crossing path (see movement of the climbing rail 18 according to the figures 6c to 6d) and a movement of the climbing rail 18 in the direction opposite to the climbing direction, ie the negative Y-direction, the climbing rail 18 is suspended in the climbing shoe 36. Due to the displacement of the climbing rail 18 relative to the climbing lifting rail 24 in the direction opposite to the climbing direction, the distance 3D' of the upper edge of the climbing rail 18 to the upper edge of the climbing lifting rail 24 is smaller than the corresponding distance 4' according to FIG Figure 6d . The fixing means 7 is still in the open position.

In Figure 6f the climbing lifting rail 24 is completely retracted relative to the climbing rail 18, ie shifted by the maximum stroke length of the lifting device 26 relative to the climbing rail 18, which is stationary relative to the structure 1, in the climbing direction, ie the Y direction. Consequently, the stroke length 2 of the lifting device 26 is zero, as has already been shown in Figure 6a is shown. The distance 3D" from the upper edge of the climbing rail 18 to the upper edge of the floor slab 50 is according to the corresponding distance in Figure 6e unchanged because the climbing rail is still hooked into the climbing shoe 36. On the other hand, the distance 2' from the upper edge of the climbing rail 18 to the upper edge of the climbing lifting rail 24 is smaller by the stroke length 3D than the corresponding distance 3D' according to FIG Figure 6e . The fixing means 7 is still in the open position.

In 6g the fixing pawl 8 is applied to the side of the climbing lifting rail 24 facing the fixing pawl 8 in such a way that the fixing means 7 is in the applied position A. The scaffolding unit 11 is still hooked into the climbing shoe 36 via the climbing rail 18 and, compared to the position of the climbing lifting rail 24 in relation to the climbing rail 18, there is in 6g to Fig. 6f no change such that the distance 2' of the top edge of the climbing rail 18 to the top edge of the climbing lifting rail 24 and the distance 3D" of the top edge of the climbing rail to the top edge of the floor slab 50 are unchanged. Consequently, the lifting device is still in the fully retracted position State with stroke length 2, which is zero.

In Fig. 6h a cylinder of the lifting device 26 is extended in such a way that the climbing lifting rail 24 absorbs the load in the climbing shoe 34 . You can see in the comparison Figures 6e and 6f that an upper edge of the climbing lifting rail has passed through the climbing shoe 34 and has passed the climbing shoe crossing path. Compared to 6g it becomes clear that in Fig. 6h the climbing lifting rail has moved in the opposite direction to the climbing direction, i.e. negative Y-direction, with the climbing rail stationary, as a result of which the climbing lifting rail 24 can be suspended in the climbing shoe 34 in order to absorb the vertical load of the scaffolding unit 11 of the climbing system 10. Since the lower end of the hoist is connected to the climbing rail and the upper end of the hoist is stationary relative to the structure 1 corresponding to the climbing rail, the stroke length 3A is greater than the stroke length 2 in FIG Figure 6g such that the climbing lifting rail is displaced in the opposite direction to the climbing direction in order to be hooked into the climbing shoe 34 in its upper section. The fixing means 7 is still in the applied position A. While the distance 3D" from the upper edge of the climbing rail to the upper edge of the floor slab is equal to this distance in Figure 6d remains, the distance 3A' from the upper edge of the climbing rail 18 to the upper edge of the climbing lifting rail 24 is opposite the corresponding distance 2' Figure 6g increased by the stroke length 3A.

In Figure 6i the lifting device is further extended and the climbing system 10 is raised in the climbing direction in order to transfer the fixing means 7 from the applied position to the closed position. Since the scaffold unit 11 is hung on the climbing shoe 34, by extending the hoist with the stroke length 3C, which is greater than the stroke length 3A, according to FIG Figure 6h , the climbing rail is shifted in the climbing direction such that the distance 4" of the top edge of the climbing rail to the top edge of the floor slab is in contrast to the corresponding distance 3D" according to Figure 6h is now zero. Since the climbing lifting rail is stationary in relation to the building 1 due to the suspended state of the climbing lifting rail in the climbing shoe 34, the extension movement of the lifting device increases the distance 3C' between the upper edge of the climbing rail and the upper edge of the climbing lifting rail compared to the corresponding distance 3A' Fig. 6h enlarged. There is one of the fixing recesses 24' is not yet level with the fixing lug of the fixing pawl 8, the fixing means 7 is still in the applied position A.

In Fig. 6j the scaffolding unit 11 of the climbing system 10 is lowered by moving the climbing rail in the opposite direction to the climbing direction, i.e. negative Y-direction, with the climbing lifting rail stationary in relation to the building 1, so that the fixation 7 moves from the applied position A to the closed position G is transferred. Since the vertical load of the climbing system 10 and in particular the scaffolding unit 11 is transferred to the structure 1 via the climbing lifting rail and the climbing shoe 34, the climbing shoes 32 and 36 are free of vertical loads. The lowering of the climbing rail relative to the climbing lifting rail in the opposite direction to the climbing direction is reflected in the fact that the stroke length 3B is smaller than the stroke length 3C according to FIG Figure 6i . The distance 3B' from the upper edge of the climbing rail to the upper edge of the climbing lifting rail is smaller than the corresponding distance 3C' according to the difference between the stroke lengths 3B and 3C Figure 6i . The difference in stroke lengths 3B and 3C is reflected in the distance 3E" from the top of the climbing rail to the top of the floor, which is in contrast to the corresponding distance 4" according to Figure 6i is no longer equal to zero. Immediately after the fixing lug 8' engages in the fixing recess 24', which is arranged at the same height as the fixing lug 8', no load is yet absorbed by the closed fixation, because the movement of the climbing lifting rail 24 to the climbing rail 18 in the climbing direction must continue until the underside the fixing lug 8' comes to rest on the fixing underside 24‴ of the fixing recess 24'.

In Figure 6k the climbing rail is therefore lowered in relation to the climbing lifting rail suspended in the climbing shoe 34 until, after the fixing lug 8' engages in the fixing recess 24', the underside of the fixing lug 8' is on the fixing underside 24‴ facing the underside of the fixing recess engaged with the fixing pawl 8 24' rests in such a way that the vertical load of the scaffolding unit 11 is diverted via the climbing rail 18, the fixing means 7, the climbing lifting rail 24 and the climbing shoe 34 into the outer wall of the building 1. The distance 3F" from the upper edge of the climbing rail to the upper edge of the floor slab is therefore slightly larger than that corresponding distance 3E" according to Fig. 6j . Because the climbing rail 24 is resting against the floor 50, the climbing rail is offset from the top of the climbing rail by the distance 3A' from the top of the climbing rail, which is less than the corresponding distance 3B' in FIG Fig. 6j is. After the fixing nose 8' engages in the fixing recess 24' according to FIG Fig. 6j , through which the closed position G of the fixing means 7 is effected, is in Figure 6k the climbing rail by the difference in stroke lengths 3A and 3B according to Fig. 6j further displaced in the direction opposite to the climbing direction relative to the climbing lifting rail until the fixing lug 8' rests against the fixing underside 24‴ of the fixing recess 24' in order to transfer the vertical load of the scaffolding unit 10 via the climbing lifting rail 24 and the climbing shoe 34 into the outer wall of the structure 1 derive.

The last concreting section to create the floor slab 50 has a stability that does not yet allow the climbing system 10 to be suspended in the climbing shoe 36 . This condition is avoided in that the climbing lifting rail 24 is fixed to the climbing rail 18 by means of the fixing means 7 in the closed position G in such a way that the vertical load is not dissipated into the building 1 via the climbing shoe 36 but via the climbing shoe 34 . In this way, the last concreting section concreted is freed from dissipating the vertical load of the climbing system and another concreting section can be started earlier, which follows the last concreted concreting section with the floor slab 50 in the Y direction, i.e. in the climbing direction. this is in Figure 6k indicated by the formwork 13 mounted on the vertical beams 13' being positioned in the negative X direction relative to their position according to FIG Fig. 6j shifted in such a way that further concreting can proceed. Therefore, a side of the formwork 13 facing the building 1 is aligned with the outside of the last concreted concrete section of the building 1.

It is also possible that instead of hanging the climbing lifting rail 24 in the climbing shoe 34, the climbing lifting rail is suspended in the climbing shoe 32, which is located in the opposite direction to the climbing direction, i.e. the negative Y-direction, below the climbing shoe 34. In the illustrated embodiment according to the Figures 1 to 6 the upper edge of the climbing rail 18 is arranged above the upper edge of the climbing lifting rail 24 in the climbing direction. It is also possible for the upper edge of the climbing rail 18 to be arranged below the upper edge of the climbing lifting rail 24 in the opposite direction to the climbing direction. In this case, too, a vertical load of the climbing system 10 can be dissipated via the fixing means 7 in the closed position G via the climbing rail 18 suspended in a climbing shoe into the structure 1 such that a formwork 13 attached to the climbing lifting rail 24 in the climbing direction above the climbing rail 18 can be used earlier for concreting the next concreting section than would be the case if the fixing means 7 were not present and the climbing rail 18 or climbing lifting rail 24 were hooked into the climbing shoe that is attached to the last concreted section.

The features of the invention described with reference to the illustrated embodiment, such as the tab 8"" of the fixing pawl 8 for mechanically actuating the fixing pawl 8, can also be present in other embodiments of the invention, such as a motor-operated fixing pawl 8 for automatic operation of the Fixing agent 7, unless otherwise stated or prohibited for technical reasons.
