Description

The invention relates to a lifting drive for 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 climbing shoes that can be arranged in a fixed position on a building, and at least one climbing rail guided by the climbing shoes, which in a scaffolding unit can be integrated or attached to the scaffold 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 scaffold, climbing protection wall and / or climbing work platform with this lifting drive.

Such lifting drives with hydraulic cylinders are in the German published application DE 10 2016 205 956 A1 and in the international patent application WO 2009/117986 A1 described as prior art for a climbing system. In construction, climbing systems such. 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 equipped with a work platform as a scaffold unit and can be moved independently of the crane from a lower finished concrete wall section of the concrete structure to be created or completed to a cured further concrete section of the concrete structure located above. Then a climbing rail that can be moved upwards, i.e. climbed, via a hydraulic cylinder that is supported on a climbing shoe. Alternatively, a work console or work platform can be raised by means of climbing cylinders which are fastened to a climbing console fastened by means of anchor bolts in a concrete wall 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 for the next climbing section or concreting section has to be carried to the next higher floor each time. Depending on the lifting drive used, a leading rail may also be necessary, which must be attached to the structure manually, whereby the climbing direction on the climbing system must be manually switched when 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 designed to be so large that when using the climbing system, the length of the climbing rails means that a height of the building must first be sufficient so that the lower free ends of the climbing rails do not touch the floor on which the first concreting section is built will collide, or a floor slab that can be erected below the first concreting section. Climbing systems driven by geared motors, on the other hand, are expensive and prone to repairs, so that drives with gearboxes cannot provide an adequate alternative to the much simpler lifting drives.

In contrast, the object of the present invention is to provide a simply constructed lifting drive which enables continuous climbing. In addition, a lifting drive is to be provided with which step-by-step climbing is possible without the high manual effort previously required after each lifting operation. After all, the linear actuator should be of a compact design so that it can be used as flexibly as possible with a rail-guided climbing system.

This object is achieved by a lifting drive with the features of claim 1 and a method for climbing a rail-guided climbing system with the features of claim 18. The subclaims indicate appropriate further training.

The object of 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 scaffold, climbing protection wall and / or climbing work platform, with climbing shoes that can be arranged in a fixed position on a building, at least one climbing rail guided by the climbing shoes, the can be integrated into a scaffolding unit or can be fastened 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 hung in at least one of the climbing shoes in one direction and can be removed in the opposite direction to this direction and displaceable relative to the 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 such that a length of a stroke of the lifting device corresponds to a displacement of the climbing lifting rail relative to the climbing rail. The length of the stroke of the lifting device is sufficient when the climbing lifting rail is suspended in order to hang the climbing rail offset by a hanging distance of the climbing rail.

According to the invention, a climbing lifting rail is as guided by the climbing rail and Compared to the climbing rail slidable unit is provided which is connected to the climbing rail via the lifting device. A climbing lifting rail that is restricted in its movement by the climbing rail and that moves up and down relative to the climbing rail is movably connected to the climbing rail. The climbing lifting rail is held or guided, for example, by guide shoes on the climbing rail on the climbing rail. A movement of the climbing lifting rail relative to the climbing rail is realized by a lifting device that can be extended and retracted. The lifting device can be detachably fixed to the climbing rail at its upper or lower end, that is to one end, the lifting device at its lower or upper end, that is to say the other end, that is to say the other end, to have an engagement and fastening tab which is connected to the climbing rail firmly, that is, not easily detachable, connected.

In order to achieve an upward movement of the climbing rail both when the lifting device is extended and when it is retracted, the length of the lifting device stroke is selected such that it is sufficient to hang 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 attaching the climbing rails, at least one hanging distance of the climbing rail from the lifting device must therefore be covered when the climbing lifting rail is attached. 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 scaffold 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 hung in at least one of the climbing shoes in one direction and can be removed in the opposite direction to this direction and can be displaced with respect to the at least one of the climbing shoes, each extension and retraction step of the lifting device can be dispensed with manually. For the next climbing section or concreting section, the lifting device no longer has to be carried dismantled to the next higher floor.

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 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, which results in a compact construction 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 extremely simple and, accordingly, inexpensive feasible, low-loss operation and not prone to repairs.

In a preferred embodiment of the invention, the length of the stroke is also sufficient to cover a suspension stroke distance of the climbing lifting rail. In this way, the climbing rail can be suspended 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 in the climbing lifting rail. The suspension stroke distance can be selected 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, from 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 either be designed to hang in the climbing rail or the climbing lifting rail or to hang in both the climbing rail and the climbing lifting rail. In this way, conventional climbing shoes can be used to hang 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 in both the climbing rail and the climbing lifting rail.

The connection between the climbing lifting rail and the climbing shoe is preferably established in such a way that the climbing lifting rail in the climbing shoe designed to hang the climbing lifting rail by means of at least one latching / snap element and a plurality of holding elements for holding the at least one latching / snap element or by means of a plurality of latching elements. / Snap elements and at least one holding element for holding at least one latching / snap element of the plurality of latching / snap elements. Here, the one or more locking / snap elements are located on the climbing shoe designed to hang the climbing lifting rail and the or the holding elements are on the climbing lifting rail or the holding element or elements are on the climbing shoe designed to hang the climbing lifting rail and the locking or snap elements are on the climbing lifting rail. In this way, the climbing lifting rail can be manufactured simply and reliably with the climbing shoe.

The locking / snap element is preferably designed as a movable element, which is in particular pivotable, foldable or displaceable, in the form of a pawl, in particular locking pawl or climbing pawl, a notch, in particular locking nose, or a bolt, in particular locking bolt. On the climbing lifting rail, the latching / snap elements can be provided one behind the other in the form of the climbing pawls or folding latches. Alternatively, the holding elements in the form of holding recesses for engaging with the at least one locking / snap element of the climbing shoe can be introduced one after the other in the climbing lifting rail, as is given below in the embodiments described with reference to the figures, or holding knobs can be applied, for example welded, onto the climbing lifting rail , his.

In a preferred embodiment, the climbing lifting rail has the holding recesses on at least one side in such a way that the climbing lifting rail is in the form of a profile with a hanging contour, in particular with serrations. Alternatively, in particular if there is only one latching / snap element on the climbing shoe designed to hang the climbing lifting rail, the climbing lifting rail can have the holding recesses in the form of completely bordered holes, also called ears. Fully bordered holes as holding recesses have a higher stability than incompletely bordered recesses between toothings, in particular if only one latching / snap element has to carry the climbing system when the lifting device is extended. On the other hand, serrations that arise, for example, between rectangular or square recesses, are easier to manufacture and therefore less expensive than perforated patterns. The climbing lifting rail can be depending on the application, e.g. B. required stability and / or cost specification, made from solid material, for example pressed or embossed, or as a hollow profile, for example in a lasered form.

A latching / snap element arranged in or on the climbing shoe is preferably designed in the form of a climbing pawl for hanging in both the climbing rail and the climbing lifting rail. Because of the double function of this climbing pawl, the climbing shoe can be constructed more easily than in the case in which a climbing pawl is to be provided for attaching both the climbing rail and the climbing lifting rail.

The climbing rail and the climbing lifting rail can be arranged one inside the other or side by side, depending on the application.

In the case of an arrangement lying one inside the other, the guidance of the climbing lifting rail by the climbing rail may be more effective than in the case of an arrangement lying next to one another, which arrangement can be easier to implement than the arrangement lying one inside the other.

The climbing lifting rail preferably has a rectangular profile or cross-sectional profile in the form 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 and pinion drive can be used as the lifting device, wherein the spindle or rack and pinion drive can be driven, for example, by an electric motor, an actuator or a linear drive. An ordinary standard hydraulic cylinder can therefore be used according to the invention.

If the climbing rail is designed to be pivotable by at least 4 degrees with respect 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 scaffold unit, into which at least one of the climbing rails is integrated or to which the at least one climbing rail is fastened, 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 by a predetermined distance. The load capacity of the climbing system can be increased by using several climbing rails at the same time. In order to provide a building with a complete climbing system, 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 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, which corresponds approximately to a floor height of the building or a fraction thereof. With a spacing of approximately one storey 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 storey height. Intermediate climbing cycles only for setting or removing the climbing shoes without further work, such as boarding, concreting, etc. can be avoided.

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 the lifting drive according to the invention also belongs to the invention. The process includes the steps:

• - Extending the lifting device with the climbing rail suspended, the climbing lifting rail being moved downwards relative to the climbing rail until the climbing lifting rail is suspended,
• Continuation of the extension movement of the lifting device, further downward displacement of the climbing lifting rail being prevented by the climbing lifting rail being hooked in, and the climbing rail being detached and being displaced upwards by at least one hanging distance of the climbing rail relative to the climbing lifting rail,
• - Retracting the lifting device, the climbing rail being shifted downward relative to the climbing lifting rail until the climbing rail is hooked in displaced upwards by at least one hanging distance, and
• - Continuation of the retracting movement of the lifting device, wherein a further downward displacement of the climbing rail is prevented by the climbing rail being hooked in and the climbing lifting rail is unhooked and displaced upwards by at least the one hanging distance of the climbing rail relative to the climbing rail.

For example, the lifting device extends until the lower of at least three climbing shoes, which are able to simultaneously guide the climbing rail, hooks into the climbing lifting rail. A further downward movement of the climbing lifting rail relative to the building is then no longer possible and the further lifting of the lifting device pushes the climbing rail to which the scaffold unit is attached, via the climbing lifting rail, which is now fixed relative to the building and is connected to the lifting device, in the direction the climbing rail upwards until it is hooked in. The climbing rail is thus 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 carried off in the lower climbing shoe in 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 hooking distance, the climbing rail runs over the top of the three climbing shoes. After completing the climbing stroke, when the lifting device is retracted, the vertical load is changed from the lower to the upper climbing shoe, in which the climbing rail is now suspended. Other embodiments are possible, wherein each climbing shoe that is located in the area of the climbing lifting rail can serve for the upward push-off. In the above embodiment, the climbing shoe with a holding function for holding the climbing rail is above the climbing shoe for hanging and supporting the climbing lifting rail. The climbing shoe with holding function for holding the climbing rail, which can be designed as a climbing shoe with an additional pawl, can however be arranged at any point 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 further floors of the building or a concreting section of the building to be concreted.

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 operations for climbing a scaffold unit 11 around a floor of a building 1 , The construction 1 comprises several floors with outer walls 40 . 44 . 48 . 52 in cross-sectional view through cutouts 41 . 45 . 49 . 53 , for example for installing windows, in the vertical direction Y are shown separately from each other. The superimposed floors of the building 1 with storey heights 42 . 46 . 50 . 54 are through floor ceilings 43 . 47 . 51 . 55 connected with each other.

The climbing system 10 includes a scaffold unit 11 with a formwork platform 12 with a formwork 13 that together in the horizontal direction 14 to the building 1 there and / or from the building 1 can be moved away around a concreting section, for example of a floor of the building 1 finish. Below the formwork platform 12 is a working platform 16 arranged on the formwork platform 12 is fixed. On the work platform 16 can be a control unit for operating a drive for moving the casing and / or a lifting device 26 be arranged for climbing the climbing system. The lifting device 26 is located on a below the work platform 16 arranged and on the work platform 16 fixed caster platform 22 , The scaffolding unit 11 therefore includes in the 1a shown climbing system 10 the formwork platform 12 who have favourited Working Platform 16 and the caster stage 22 , taking a climbing rail 18 into the scaffold unit 11 is integrated. A fastening of the climbing rail 18 on the scaffolding unit 11 is possible, too. The trailer platform 22 is used for attaching and removing climbing shoes 32 . 34 . 36 . 38 working on the structure 1 are stationary and a guide and support of the climbing rail 18 serve the scaffolding unit 11 wearing.

The climbing rail 18 has holes 19 and each at a hook-in distance 20 vertically spaced support bolts 19 ' on, also called spacings, which are so in each of the climbing shoes 32 . 34 . 36 . 38 intervene that the climbing rail 18 each in at least one of the climbing shoes 32 . 34 . 36 . 38 in the vertical direction, e.g. B. with a downward movement, can be hooked in and in the opposite direction to this direction, ie upwards, can be unhooked and opposite the respective climbing shoe 32 . 34 . 36 . 38 is movable.

According to the invention, it is not only the climbing rail 18 , but also a climbing lifting rail 24 that are relative to the climbing rail 18 slidable and off the climbing rail 18 is present, in each case in at least one of the climbing shoes 32 . 34 . 36 . 38 Can be hung in one direction and unhooked in the opposite direction and opposite to at least one of the climbing shoes 32 . 34 . 36 . 38 displaceable. In addition to the tour through the climbing rail 18 is the climbing lifting rail 24 only via the lifting device 26 with the climbing rail 18 connected. In the present exemplary embodiment, the lifting device is at its lower end 27 with the climbing lifting rail 24 and with their top end 28 with the climbing rail 18 connected.

At the beginning of the climbing process, the lifting device, more precisely a lifting cylinder or plunger of the lifting device, is completely retracted, so that a stroke length 2 the lifting device is zero. With the lifting device retracted 26 lies between a height 25 an upper edge of the climbing lifting rail 24 and that of a height 21 an upper edge of the climbing rail 18 a distance 2 ' in front. The climbing rail 18 is in the climbing shoe 34 mounted so that a vertical load is transferred via this climbing shoe.

In 1b is the lifting device 26 by a stroke length 3 extended that is non-zero. The climbing rail 18 is still in the climbing shoe 34 hooked in and the climbing lifting rail 24 moves down so that the height 25a the top edge of the climbing lifting rail 24 about the distance 3 ' versus height 25 the climbing lifting rail 24 , in the 1a shown is shifted down. Because the climbing rail 18 versus their height in 1a has not moved, the length corresponds 3 the stroke of the lifting device 26 the shift 3 ' the climbing lifting rail 24 relative to the climbing rail 18 , The lifting device 26 extends until the climbing lifting rail 24 in the climbing shoe 32 attaches, which however in 1b is not yet the case.

In 1c is the lifting device 26 around the stroke length 4 that are larger than the stroke length 3 fails, extended, so that the climbing lifting rail 24 now in the climbing shoe 32 has attached. Because the climbing lifting rail 24 due to their attachment to the climbing shoe 32 cannot move further down, is replaced by the Kletterhubschiene 24 now the climbing rail 18 moved up. So the whole climbing system 10 including scaffolding unit 11 raised upwards. Opposite the height 21 the top edge of the climbing rail 18 in 1a and 1b is the height 21a the top edge of the climbing rail in 1c about the distance 4 ' moved up. The length 4 the stroke of the lifting device 26 is composed of the distance 3 ' around which the climbing lifting rail 24 versus their height in 1a drove down, and from a distance 4 ' around which the climbing rail 18 versus their height in 1a has gone up. The length 4 the stroke of the lifting device 26 is sufficient with the climbing lifting rail attached 24 out to the climbing rail 18 by the hanging distance 20 put in the climbing shoe 36 mount. There will be at least the hanging distance 20 painted over. The lifting device 26 so push the climbing rail 18 based on the climbing lifting rail 24 that on the lower climbing shoe 32 is supported by at least the hanging distance 20 up. In case of 1c becomes the climbing rail 18 by the hanging distance 20 offset and additionally by a stopping point distance, which is required to the climbing rail 18 in the climbing shoe 36 mount. The stopping point of the climbing shoe 36 from the climbing rail 18 is climbed over to the climbing rail 18 to be able to hang in this climbing shoe. The support bolt 19 ' the climbing rail 18 is therefore above a hanging height 36 ' of the climbing shoe 36 , The breakpoint distance is approximately the vertical distance between two adjacent holes 19 the climbing rail 18 , In other versions, the breakpoint distance can be smaller or reduced to zero. In this case, it is sufficient if the climbing lifting rail is attached 24 the stroke length 4 the hanging distance 20 the climbing rail 18 can paint over. Since the climbing rail by the hanging distance 20 can be moved upwards, it is not necessary to have a stroke length greater than the stroke length 4 provided. The stroke length 4 is therefore the maximum stroke length in the present exemplary embodiment. Higher maximum stroke lengths are still possible.

In 1d becomes the lifting device 26 retracted so the stroke length 5 is smaller than the stroke length 4 in 1c , Opposite the height 21 the top edge of the climbing rail 18 in 1a and 1b is the height 21b the top edge of the climbing rail by the distance 5 ' moved up. This distance is smaller than the distance by the breakpoint distance 4 ' in 1c and is the hanging distance 20 so the climbing rail 18 in the climbing shoe 36 is attached. This can be seen from the fact that the support bolt 19 ' at the height of the hanging height 36 ' of the climbing shoe 35 located. Because the lifting device 26 with the stroke length 5 by more than the breakpoint distance from the stroke length 4 is retracted and the climbing rail 18 due to their attachment to the climbing shoe 36 cannot move further down instead of the climbing rail 18 now the climbing lifting rail 24 moved up. Opposite the height 25 the top edge of the climbing lifting rail 24 in 1a is the height 25b the top edge of the climbing lifting rail only by the distance 5 ' downwards, this distance being smaller than the distance 3 ' in 1b and 1c , The length 5 the stroke of the lifting device 26 is composed of the distance 5 ' around which the climbing lifting rail 24 versus their height in 1a drove down, and from a distance 5 ' around which the climbing rail 18 versus their height in 1a has gone up. Without moving the scaffolding unit 11 that over the climbing rail 18 in the climbing shoe 36 is attached, so the climbing lifting rail 24 pulled up.

In 1d is the lifting device 26 completely retracted. Hence the stroke length 2 zero. As in 1c shown is the height 21b the top edge of the climbing rail 18 about the distance 5 ' , which is the insertion distance 20 corresponds, shifted upwards. The support bolt 19 ' is at the height of the hanging height 36 ' of the climbing shoe 35 and the climbing rail 18 is about the hanging distance 20 versus their height in 1a offset upwards, like a comparison of the heights 21 and 21b the top edges in 1a and 1d can be seen. Even the height 25c the top edge of the climbing lifting rail 24 is opposite their height 25 in 1a by the hanging distance 20 that as a distance 5 '' in 1d is shown, offset upwards, so that the distance 2 ' the top edges 21b and 25c the climbing rail from the climbing lifting rail the distance 2 ' in 1a equivalent. The climbing rail 18 hangs with the lifting device retracted 26 in 1d in the climbing shoe 36 , In 1a hung the climbing rail 18 with the lifting device retracted 26 in the climbing shoe 34 ,

2 shows that in 1b illustrated climbing system 10 in a side view. The climbing lifting rail 24 lies in the climbing rail 18 such that the climbing lifting rail cannot be seen. The formwork 13 is on a vertical support 13 ' assembled for the formwork. At the top of the vertical beam 13 ' is a railing 13 " attached to ensure safe working in this area.

In 2 B is a top view of the in 1b and 2a illustrated climbing system 10 with two climbing rails arranged parallel to each other 18 , Next to the formwork platform 12 , the working platform 16 and the trailer platform 22 are the formwork 13 with vertical support 13 ' and railings 13 " as well as the clippings 41 . 45 . 49 in the outer wall 44 of the building 1 shown.

3a shows the detail B of the lower area in 2a in an enlarged representation in cross section. In this respect shows 3 the already in 1b shown section with guide shoes 19 " the climbing rail 18 in which the climbing lifting rail 24 are led. The climbing rail 18 is in the climbing shoe 34 hooked in, the support bolt 19 ' approximately in the middle in the vertical direction to the climbing shoe 34 is hooked into this.

3b shows in cross section along the plane AA in 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 double T-shaped cross section. The climbing lifting rail 24 is in the climbing track 18 between the U-shaped elements of the climbing rail 18 arranged and made of guide shoes 19 " , which is also between the U-shaped elements of the climbing rail 18 are arranged, guided.
