Description

The invention relates to a self-climbing unit, a self-climbing system and a method for implementing such a self-climbing unit on a concrete structure.

In the building industry, self-climbing units are used, for example, in the construction of vertically oriented concrete structures, in particular so-called building cores, bridges, dams and the like, as self-climbing formwork and / or self-climbing protection screen and / or in the form of self-climbing framework units. The self-climbing units are usually provided with a working platform 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 concreting section of the concrete structure located above. Lifting cylinders, so-called climbing cylinders, are used for such a climbing or relocating process, which can mostly be operated hydraulically. The climbing cylinders are supported so-called climbing brackets, which are each releasably anchored in anchor points of a lower concrete wall section of the concrete component. The work platform and, if necessary, the concrete formwork elements to be used for formwork work are each attached to or supported on so-called work consoles. The work consoles are anchored to the concrete component above the climbing consoles. During the climbing process, the work consoles are first moved upwards in the climbing or plumbing direction on the concrete structure and anchored in anchor points of the concrete structure. The climbing brackets can then be pulled upwards in the climbing or plumbing direction using the climbing cylinders and anchored in additional anchor points on the concrete structure. If the concrete structure is aligned perpendicularly, the climbing direction coincides with the vertical, ie the vertical direction. In the case of a concrete structure to be created, which is arranged at least in sections at an angle to the direction of the solder, such as, for example, a dam (dam), the climbing direction naturally deviates from the direction of the solder in a corresponding manner.

So-called anchor bolts are used for fastening, ie for anchoring the work and climbing brackets in the concreting sections. The anchor bolts mostly have a screw shape. The anchor points are formed by concrete wall anchors that are concreted in the respective concreting sections of the concrete component. Such concrete wall anchors have to be arranged in the concrete wall sections at precisely specified positions and therefore regularly collide with the reinforcing steel to be embedded there. The reinforcing steel must therefore z. Parts are laboriously led around the anchor points or, if necessary, removed in some areas in the area of the anchor points before concreting. Overall, this can lead to an undesirable structural weakening of the concrete structure, in particular with a large number of anchor points. At the same time, the number of anchor points and therefore the concrete wall anchor should also be kept as low as possible for cost reasons.

In JP S64 29573 A describes a self-ascending device in which an anchoring frame is temporarily attached to a concrete base so that the frame is freely attachable / detachable to C-bolts erected on a concrete surface, with a self-ascending mast 20 mounted on a slide frame provided by the anchoring frame is slidably held over the self-climbing device. In JP S63 261064 A describes a self-lifting formwork device with a fixed frame which is detachably mounted on a wall of the concrete, a cylinder which is fixed to the fixed frame, a guide sleeve which is slidably inserted into the cylinder, which slidably guides a leading end of the guide sleeve , a first hydraulic bushing on the cylinder, which is arranged on the cylinder and parallel to the guide sleeve and has a distal end which is connected to a support plate, a frame which is movably supported and the lower edge of which is detachably on the upper edge of an existing concrete wall surface is fixed, one end of which is connected to the support plate and the other end of which is connected to the frame, and to a second hydraulic bushing which holds said fixed frame at an arbitrary angle. In DE 196 39 038 C1 describes a climbing formwork system which has a supporting structure, to which a plurality of concrete formwork elements are attached hanging downwards, and which is connected to and supported on at least one first, upper support beam. The upper support carrier has means by which it can be supported laterally on a finished wall section. The climbing formwork system also has at least one lower support which can be supported laterally on a finished wall section. Furthermore, there is at least one lifting device through which a relative movement between the two spacers can be achieved. The upper support is designed for support on a largely flat surface. In US 4,147,483 describes a climbing formwork device comprising a plate or a series of plates with a support structure and means for successively lifting the plate to define the surface of successive superimposed layers of a cast structure, the plate being connected to a main frame which is connected by an upright element to an underframe which can be fixed to the hardened lower part of the cast structure by means of anchoring elements which are embedded in the structure during casting. The frame is hinged to the lower end of the upright element and is additionally connected to it by a linear actuator. The US 4,147,483 discloses all features of the introductory part of claim 1.

It is therefore the object of the invention to provide a self-climbing unit and a self-climbing system which require less material and assembly work and in which the risk of a structural weakening of the reinforcement of the concrete structure by anchor points for the self-climbing unit is reduced. In addition, a simplified and less time-consuming method for implementing a self-climbing unit mentioned above is to be specified.

The task relating to the self-climbing system is achieved by a self-climbing system with the features specified in claim 12, and the task relating to the self-climbing unit is achieved by a self-climbing unit according to claim 1. The method according to the invention has the features specified in claim 13.

Lotrichtung zueinander paarweise fluchtend angeordnet sind;

The self-climbing system according to the invention comprises a first concrete wall section and a second concrete wall section, which are arranged one above the other in the climbing or plumbing direction. The self-climbing system has a self-climbing unit, comprising:

• Climbing brackets, each having first anchor receptacles for anchor bolts, by means of which the climbing brackets can be releasably anchored in anchor holes from first anchor points of the first concrete wall section;
• Work consoles with second anchor receptacles for anchor bolts, by means of which the work consoles can each be detachably anchored in anchor holes from second anchor points of the second concrete wall section, one of the first anchor points of the first concrete wall section and one of the second anchor points of the second concrete wall section are arranged in pairs in the climbing or perpendicular direction;

• a work platform that can be attached to the work consoles;
• Climbing cylinders that can be attached at one end to one of the climbing brackets and at the other end to one of the work consoles and by means of which the work brackets can be moved from the second anchor points to third anchor points of a third concrete wall section of the concrete component that adjoins the second concrete wall section above the second concrete wall section are.

According to the invention, the first anchor receptacles of the climbing brackets and the second anchor receptacles of the work consoles match each other in their pattern with regard to their relative positions, in particular with respect to their longitudinal axis or a longitudinal center plane comprising the longitudinal axis. In this way, after anchoring the work consoles in the anchor holes of the third anchor points of the third concrete wall section, the climbing brackets can be moved by a return stroke movement of the climbing cylinders to the second anchor points of the second concrete wall section and anchored in the (meanwhile) free anchor holes of the second anchor points of the second concrete wall section . In the self-climbing system according to the invention and the self-climbing unit according to the invention, the anchor holes of at least part of the anchor points are used both for anchoring the work and climbing brackets. As a result, the number of anchor points or anchor holes required for anchoring the self-climbing unit in the respective concrete wall sections of the concrete structure can be significantly reduced compared to the self-climbing systems or self-climbing units available on the market. The number of anchor points or anchor holes can thus be halved or almost halved. Separate anchor points or anchor holes are only required for the lowest and lowest concrete wall section of the concrete structure to be created for the climbing and work consoles. The material and time required for the concrete wall anchors to be introduced in the area of the anchor points in the concrete wall sections is further reduced. This offers cost advantages. About that In addition, the assembly effort for the self-climbing system and the self-climbing unit is reduced and accelerated. The climbing cylinders allow the self-climbing formwork to be implemented on a floor-by-floor basis, whereby the individual concrete wall sections can have a uniform or different floor height. An external lifting device, such as a crane, is no longer required for moving the self-climbing unit on the concrete structure and in the climbing direction.

According to the invention, the assembly effort of the self-climbing unit can be further reduced by the fact that the climbing brackets and the work consoles each have (only) two anchor receptacles and each anchor point has only two corresponding anchor holes for each anchor bolt. This further reduces the risk of structural weakening or damage to the concrete structure through anchor points. The planning effort with regard to the reinforcement to be introduced into the concrete structure, which can collide with the anchor points, can also be reduced.

According to the invention, the self-climbing unit has concrete formwork elements. The concrete formwork elements are carried by or supported on the work consoles. The concrete formwork elements allow the concrete structure to be expanded successively, particularly on a storey-by-floor basis, in the vertical direction. For example, a concrete structure that functions as a building core or elevator shaft of a house can be expanded or created using the self-climbing unit.

According to the invention, the work consoles each have support columns which, when the self-climbing unit is in operation, extend upward from the work consoles in the soldering or climbing direction at least in sections. The support columns each have a plurality of fastening points for one of the climbing cylinders, which are arranged at a distance from one another along the support column. This allows the climbing cylinders to be attached (attached) to the support pillars in a graduated manner. In addition, in a Embodiment of the invention attached to the support columns, the aforementioned concrete formwork elements, in particular suspended. This means that small and large storey heights can be realized.

According to a preferred development of the invention, the support columns are each designed as a hollow profile. This allows the weight of the self-climbing unit to be minimized. In addition, the support columns can perform a protective cage function for the climbing cylinders. If the climbing cylinders each extend into one of the support columns, they are protected against mechanical damage or excessive contamination, for example by fresh concrete, without additional effort.

For the purpose of simplified attachment, in particular simplified bolting, of the climbing cylinders on the support columns, these are preferably each attached to the climbing brackets with a (slight) axial play. The axial play can be up to 15 millimeters in particular.

The lifting or climbing cylinders are preferably each designed as a hydraulic cylinder. Such hydraulic cylinders are durable, inexpensive to manufacture. On the one hand, the forces required to implement the self-climbing unit can be applied. On the other hand, hydraulic cylinders allow the self-climbing unit to be moved sensitively, relatively quietly and quickly.

According to the invention, a so-called trailing platform can be attached or supported on the climbing brackets for work in the area below the working platform or for safety reasons.

To actuate the hydraulic climbing cylinders, a hydraulic pump device with a control device is provided according to the invention, by means of which the climbing cylinders can be actuated in a synchronized manner.

The hydraulic pump device preferably has a plurality of pump units, i. H. Pump up. on. According to the invention, each pump unit can be connected to one or more of the climbing cylinders via a fluid valve that can be individually controlled by the control device. The control device preferably has a sensor for each hydraulic cylinder for detecting a respective volume flow of a hydraulic medium to / from the hydraulic cylinder. Based on the volume flow, the control device can regulate the (adjustment) speed or the actual extension length of the individual hydraulic climbing cylinders precisely synchronized with little effort. On the basis of the volume flow of the hydraulic medium recorded individually for each climbing cylinder, each climbing cylinder can be individually controlled by the control device in such a way that the climbing cylinders are adjusted (extended / retracted) exactly synchronously with one another when they are actuated. Of course, the climbing cylinders used in the construction sector are also subject to inevitable manufacturing tolerances. However, this can be compensated for by the volume flow-based control of the climbing cylinders. For example, a characteristic curve for the dependency between a volume flow of the hydraulic medium and a length adjustment of the climbing cylinder per unit of time can be stored in the control device for each climbing cylinder. The characteristic curve can be present, for example, in electronic form as table values or as an analytical function. The respective characteristic curve of a climbing cylinder can be adjusted if necessary, in particular experimentally by using an alternative time / distance measurement (scale / distance measurement by means of a laser or also by means of a light barrier system) when the climbing cylinder is actuated.

The self-climbing unit according to the invention is preferably designed as a self-climbing formwork unit.

The method according to the invention for the vertical implementation of a self-climbing unit explained above comprises the following steps:

1. a. Anchoring the climbing brackets in the anchor holes of the first anchor points of the first concrete wall section with anchor bolts which engage in the first anchor receptacles of the climbing brackets;
2. b. Anchoring the work consoles in the anchor holes of the second anchor points of the second concrete wall section by means of anchor bolts which engage in the second anchor receptacles of the work consoles, the first anchor points and the second anchor points being arranged one above the other in pairs in the climbing or soldering direction;
3. c. Detaching the work consoles from the second anchor points of the second concrete wall section;
4. d. Lifting the work consoles from the second anchor points to the third anchor points in the third concrete wall section in the climbing / plumbing direction by means of climbing cylinders which are fastened to one of the climbing brackets and one of the work consoles and anchoring the work consoles in anchor holes of the respective third anchor points using the anchor bolts;
5. e. Loosening the climbing brackets from the first anchor points of the first concrete wall section and lifting the climbing brackets in the perpendicular or climbing direction to the second anchor points of the second concrete wall section by means of the climbing cylinders; and
6. f. Anchor the climbing brackets in the free anchor holes of the second anchor points of the second concrete wall section using anchor bolts.

It goes without saying that the method according to the invention requires the use of the self-climbing unit explained above. A climbing process, ie moving the self-climbing unit in the perpendicular or climbing direction along the concrete structure, can thus be carried out overall with less material, assembly and personnel expenditure. At the same time, the number of required anchor points in the respective concrete wall sections of the finished or still to be erected concrete structure and an associated risk of structural weakening of the concrete structure can be further reduced.

With the self-climbing unit, the third concrete wall section of the concrete structure adjoining the second concrete wall section in the soldering or climbing direction above the second concrete wall section can be created by means of the concrete formwork elements between the aforementioned steps b) and d). In this case, the self-climbing unit is therefore used as a self-climbing formwork (unit).

The invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing.

Fig. 1 shows a self-climbing system 10 with a self-climbing unit 12 , which is anchored here to a first concrete wall section 14 and to a second concrete wall section 16 of a concrete structure 18 . The first concrete wall section 14 and the second concrete wall section 16 are arranged one above the other in the climbing direction 20 , which coincides here, for example, with the perpendicular direction. It should be noted that the relevant climbing direction 20, for example in the construction of dams or the like, can be arranged at an angle to the perpendicular direction. At the in Fig. 1 In the exemplary embodiment shown, the concrete structure 18 is to be expanded upwards in the direction of plumb or climbing 20 in fresh concrete construction. Above the second concrete wall section 16, a third concrete wall section 22 of the building body 18 is shown, which connects to the second concrete wall section 16 in the climbing direction 20.

It should be noted that the concrete wall sections 14, 16, 22 of the concrete structure 12 can each have a uniform or also a different (storey) height 24 . The concrete structure 18 can in particular be a so-called building or access core, which is used for the later vertical traffic or technical development of a building, not shown. Such access cores generally represent the static backbone of buildings and can in particular also form supports for the ceilings of the building. The concrete structure 18 can basically have a polygonal, in particular rectangular, an elliptical or a circular cross-sectional shape. A free-form cross section is also conceivable. In the case of a concrete structure 18 functioning as the core of the building, each concrete wall section 14, 16, 22 has two mutually opposite wall segments or is designed to be closed (at least partially) on three or even four of its sides. In the latter case, the self-climbing unit can be guided or supported on all sides on the concrete wall sections of the concrete structure 18.

According to the self-climbing unit 12 Fig. 1 several so-called climbing consoles 26 and several so-called work consoles 28 . The Climbing brackets 26 are preferably constructed identically. The work consoles 28 are also preferably identical in construction. The climbing and work consoles can have a different construction due to their different functionality.

The climbing brackets 26 are releasably anchored by means of anchor bolts 30 in anchor holes 32 from first anchor points 34 of the first concrete wall section 14. The work consoles 28 are releasably anchored by means of anchor bolts 30 in anchor holes 32 from second anchor points 36 of the second concrete wall section 16.

The first and the second anchor points 34, 36 of the two concrete wall sections 14, 16 are arranged with their anchor holes 32 in pairs in the perpendicular or climbing direction 20 one above the other in alignment. In each case, a third anchor point 38 of the third concrete wall section 22 is aligned with its anchor holes 32 in the climbing / plumbing direction 20 to one of the first anchor points 34 and one of the second anchor points 36 of the first and second concrete wall section 14, 16.

The self-climbing unit comprises a walk-on first work platform 40 which is fastened and supported on the work consoles 28. This work platform 40 is also referred to as "level 0" in the construction sector.

The self-climbing unit 12 can be moved along the concrete wall sections 14, 16, 22 by means of a plurality of climbing cylinders 42 without the use of a crane in the vertical direction 20. The climbing cylinders 42 can in particular be designed as hydraulic cylinders and then each have in the usual way a cylinder 44 and a fluid-operated piston 46 guided in the cylinder 44, which can be hydraulically extended from the cylinder 44 and retracted into the cylinder 44.

The climbing cylinders 42 are attached at one end to one of the work consoles 28 and at the other end, here each with the free end of its piston 46, to one of the climbing brackets 26 arranged underneath.

A so-called trailing platform 48 can be attached to the climbing brackets 26. The trailing stage 48 is in Fig. 1 shown with a dashed line. A support column 50 can be arranged on each of the work consoles 28. In this case, the support columns 50 preferably extend at least in sections upward from the assigned work console 28 in the perpendicular or climbing direction 20. A support frame 52 is attached to the upper end of the support columns 50. The support frame 52 comprises a plurality of cross members 54 which are connected to one another. It goes without saying that the shape and construction of the support frame 52 is matched to the cross-sectional shape of the concrete structure 18. The support frame 52 protrudes outward in the direction of a transverse axis 56 running orthogonally to the plumb direction 20 in the radial direction beyond the first and the second concrete wall sections 14, 16.

The self-climbing unit 12 is designed as a self-climbing formwork and has a plurality of concrete formwork elements 58a, 58b . The third concrete wall section 22 was created using the concrete formwork elements in fresh concrete construction. The formwork elements 58 are fastened to the support frame 52 and can in particular be suspended from the latter. Two of the formwork elements 58a, 58b are arranged opposite one another in the radial direction. The formwork elements 58a, 58b are preferably displaceably mounted on the support frame 52 of the self-climbing unit 12 in the direction of the transverse axis 56, in order to form the other concrete wall sections to be created in the climbing direction 20 above the third concrete wall section 22 and to be able to remove the formwork after their completion. In addition, due to the displaceable mounting of the formwork elements 58a, 58b, different wall thicknesses (= wall thicknesses) can be set in the respective concreting sections with little effort.

A work platform 60 can be arranged on the support frame 52. The work platform 60 is thus arranged above the work platform 40 when the self-climbing unit 12 is in operation. This work platform will be in Construction area generally referred to as "Level +1". The working platform 60 preferably has passage recesses (= pouring openings) 62 for introducing fresh concrete between the formwork elements 58a, 58b. The pouring openings 62 can be closed if necessary. The work platform 60 is provided with a railing 64 on the edge to prevent it from falling. The support frame 52 can be supported on the work consoles 28 by additional support struts 66 .

For reasons of weight, the support columns 50 are each designed as a hollow profile and can extend downwards and upwards from a work platform support 68 of the respective work console 28 in the vertical direction 20. At the in Fig. 1 Self-climbing unit 12 shown, the climbing cylinders 42 each extend in the axial direction into one of the support columns 50. The support columns 50 thereby have a protective cage function for the climbing cylinders 42. The climbing cylinders 42 are thereby largely protected against mechanical damage from the outside or against contamination.

After completion of the third concrete wall section 22, the work consoles 28 can be moved from the second anchor points 36 of the second concrete wall section 16 to the third anchor points 38 of the third concrete wall section 22 of the concrete structure 18 by means of a synchronized forward stroke movement of the climbing cylinders 42.

In Fig. 2 is an example of one of the support columns 50 of the self-climbing unit 12 Fig. 1 shown. The support columns 50 have a plurality of fastening points 70 for the climbing cylinder 42, which are arranged spaced apart from one another along the support column 50. The fastening points 70 of the support column 50 for the climbing cylinder 42 comprise through openings 72 on at least two sides of the support column arranged opposite one another. The passage recesses 72 are each aligned in pairs in the radial direction. A climbing cylinder 42 can be bolted to the support column 50 via the passage recesses 72, that is to say it can be fixed in position on the support column 50 in the axial direction. The climbing cylinders 42 become the other end preferably each fastened to the climbing brackets with a slight axial play (0.5 cm - 2 cm), so that the climbing cylinders 42 can be easily detached / bolted to the respective fastening point 70 of the respective support column 50.

In Fig. 3 12 is an exemplary embodiment of the climbing console 26 of the self-climbing unit 12 Fig. 1 in an optional side view and Fig. 4 shown in an end view.

The climbing bracket 26 has an upper wall shoe section 74 and a lower support section 76 , each of which has a contact surface 78 for a respective concrete wall section 14, 16, 22 (ie its vertical visible surface). The wall shoe section 74 serves to anchor the climbing bracket 26 to one of the respective concrete wall sections 14, 16, 22. The support section 76 essentially serves to horizontally support the work console 28 on the respective concrete wall section 14, 16, 22. The wall shoe section 74 and the support section 76 are connected to each other via a longitudinal profile 80 . Cantilever girders 82 are used to attach the trailing platform or a climbing cylinder ( Fig. 1 ).

The climbing bracket 26 has two first anchor receptacles 84a for the anchor bolts 30 ( Fig. 1 ) on. The first anchor receptacles 84a can each be designed as passage recesses in the wall shoe section 74. The anchor receptacles 82 are in accordance with Fig. 4 arranged on a transverse axis 88 running orthogonally to the longitudinal axis 86 of the console and spaced apart from one another by a distance 90 . The first two anchor receptacles 84a are here arranged in mirror symmetry with respect to a longitudinal center plane 92 of the climbing bracket 26 which comprises the longitudinal axis of the bracket and which is orthogonally oriented to the contact surfaces 78.

The climbing bracket 26 is in the assembled state on one of the concrete wall sections 14, 16, 22 of the concrete structure 18 ( Fig. 1 ) with its console longitudinal axis 84 in one of the concrete wall sections 14, 16, 22 correspondingly aligned vertically or essentially vertically. As a result, the transverse axis 88 is arranged to run horizontally or substantially horizontally in the assembled state of the climbing bracket 26.

In Fig. 5 is a work console 28 of the in Fig. 1 Self-climbing unit 12 shown in an isolated side view and in Fig. 6 shown in an end view. The work console 28 points in one to that in the Fig. 3 and 4 Climbing console 26 shown in a corresponding manner has an upper wall shoe section 74 and a lower support section 76, which are each provided with contact surfaces 78 for a respective concrete wall section 14, 16, 22 (ie their vertical visible surface). The wall shoe section 74 and the support section 76 are connected to one another purely by way of example via two longitudinal profiles 80. Cantilever beams 82 serve to support the work platform 40 or one of the support columns 50 ( Fig. 1 ).

Analogous to the climbing console 26, the work console 28 each has two second anchor receptacles 84b for anchor bolts 30 ( Fig. 1 ) on. The second anchor receptacles 84b are arranged at a distance 90 from one another on a transverse axis 88 of the climbing bracket 26 which runs orthogonally to the longitudinal axis 86 of the bracket. The two second anchor receptacles 84b are arranged in mirror symmetry with respect to a longitudinal center plane 92 of the climbing console 26 which comprises the longitudinal axis 86 of the bracket and which is oriented orthogonally to the contact surfaces 78 of the climbing bracket 26. In the assembled state, the work console 28 has on one of the concrete wall sections 14, 16, 22 a console longitudinal axis 86 running in the direction of the climbing direction 20, that is to say here perpendicular or essentially perpendicular. As a result, the transverse axis 88 is arranged horizontally or essentially horizontally in the assembled state of the climbing bracket 26.

The second anchor receptacles 84b of the work consoles 28 and the first anchor receptacles 84a of the climbing consoles 26 are therefore correct in their pattern with each other with respect to their relative positions on their respective wall shoe part.

In Fig. 7 the first and the second concrete wall section 14, 16 and the third concrete wall section 22 of the concrete structure 18 after its completion (hardening) are shown in sections and together with a climbing bracket 26 and a working bracket 28. The climbing console 26 and the work console 28 are reproduced in a highly schematic manner.

The anchor points 34, 36, 38 of the concrete wall sections 14, 16, 22, arranged vertically one above the other, each have two anchor holes 32 for the anchor bolts 30 in a manner corresponding to the anchor receptacles 84a, 84b of the work console 28 and the climbing console 26 their relative positions correspond to each other and also to the relative position of the anchor receptacles 84a, 84b of the climbing 26 and work console 28 on the wall shoe parts 74.

Thus, an anchor hole 32 of the first anchor point 34 of the first concrete wall section 14, an anchor hole 32 of the second anchor point 36 of the second concrete wall section 14, and an anchor hole 32 of the third anchor point 38 of the third concrete wall section 22, or respectively an anchor hole of each additional anchor point arranged above it another concrete wall section in the climbing direction 20 aligned with each other.

As a result, the climbing bracket 26 anchored in the first anchor point 34 of the first concrete wall section 14 can, after lifting the work consoles to the anchor holes 32 of the third anchor points 38 of the third concrete wall section, by a return stroke movement (= insertion of the pistons 46 into the cylinders 44) of the climbing cylinders 42 second anchor points 36 of the second concrete wall section 16 are moved and anchored in the exposed anchor holes 32 of the second anchor points 32 of the second concrete wall section 16. In the Figures 8 and 9 the self-climbing unit is off Fig. 1 shown in two successive phases of a climbing or relocating process. According to Fig. 8 the work consoles 28 were released from their anchoring at the second anchor points 36 of the second concrete wall section 16 and, by means of a forward stroke movement of the climbing cylinders 42 in the vertical or climbing direction 20, were moved up to the third anchor points 38 of the finished (hardened) third concrete wall section 22. The work consoles 28 are anchored by means of anchor bolts 30 in the anchor holes 32 of the third anchor points 38. The climbing cylinders are dimensioned such that they can span two full storey heights 24 of the concrete wall sections. A corresponding static design of the climbing cylinders is therefore essential.

According to the representation of the self climbing system in Fig. 9 the climbing brackets 26 were released from their anchorage in the anchor holes 30 of the first anchor points 34 of the first concrete wall section 14 and moved by a return stroke movement of the climbing cylinders 42 to the second anchor points 36 of the second concrete wall section 16. The climbing brackets 26 are anchored with two anchor bolts 30, which engage in the first anchor receptacles 84a of the climbing brackets 26, in the exposed anchor holes 30 of the second anchor points 36 of the second concrete wall section 16. The concrete formwork elements 58a, 58b of the self-climbing unit 12 are then available for shuttering a further, here fourth, concrete wall section, which directly adjoins the third concrete wall section 22 in the climbing direction 20 above the third concrete wall section 22.

In the self-climbing system according to the invention, the same anchor holes of the anchor points of superimposed concrete wall sections of a concrete structure can thus be used alternately for the work consoles and for the climbing consoles.

Fig. 10 shows a block diagram of the self-climbing unit 12 explained above. The climbing cylinders 42 are each connected to a hydraulic pump device 96 via one or more hydraulic lines 94 . The Hydraulic pump device has a control device 98 for controlling the individual pump units 99 (pumps) of the hydraulic pump device 96. Each pump unit 99 can serve to actuate a climbing cylinder 42 or, if necessary, also a plurality of climbing cylinders 42. It goes without saying that the pump assemblies 99 in the latter case have at least one fluid valve F which can be controlled by the control device 98 for each climbing cylinder 42 fluidly connected to the pump assembly 99. In this case, too, the volume flow of the hydraulic medium can be regulated individually for each individual climbing cylinder. When relocating the self-climbing unit 12, which can have several dozen of the climbing cylinders shown, the work consoles 28 with their second anchor receptacles 84b and the climbing consoles 16 with their first anchor receptacles 84a all have to be as exact as possible in front of the predefined anchor holes 32 of the respective anchor points 34, 36, 38 of the relevant concrete wall section 14, 16, 22 are positioned. The control device 100 can therefore have a sensor 100 for each climbing cylinder 42 for detecting a respective volume flow 102 of a hydraulic medium for actuating the climbing cylinder 42. The sensors 100 can also be arranged in the housing of the control device designated 98. On the basis of the individually recorded volume flow of the hydraulic medium, each hydraulic cylinder 42 can be individually controlled by the control device 98, in such a way that the climbing cylinders are adjusted (extended / retracted) exactly synchronously with one another when they are actuated. The climbing cylinders 42 of the self-climbing unit 12 are of course subject to unavoidable manufacturing tolerances and are subject to varying degrees of wear. An individual characteristic curve 104 for the dependency between a volume flow of the hydraulic medium and an associated actual length adjustment of the climbing cylinder 42 per unit of time can therefore be stored in the control device 98 for each climbing cylinder 42. The characteristic curve 104 can be present, for example, in electronic form as table values or as an analytical function. It goes without saying that the control device 98 must have a CPU (not shown) and a suitable storage medium 106 for storing the characteristic curve 104.

The self-climbing unit 12 explained above is designed as a self-climbing formwork unit. The self-climbing unit 12 can also be used without the concrete formwork elements 58a, 58b, i.e. H. in the form of a self-climbing scaffold, can be used in the construction sector, but this is not part of the invention. The concrete structure 18 can then, for example, be a completed building core, for example in the unfinished state.

The following is a method 200 according to the invention for implementing the self-climbing unit 12 explained above with additional reference to FIG Fig. 11 explained. In a first step 202 , the climbing brackets 26 are anchored with the anchor bolts 30 in the anchor holes 32 of the first anchor points 34 of the first concrete wall section 14.

Each anchor bolt 30 engages in one of the second anchor receptacles 84b of the climbing brackets 26.

In a further step 204 , the work consoles 28 are anchored with anchor bolts 30 in the anchor holes 32 of the second anchor points 36 of the second concrete wall section 16. The anchor bolts 30 each engage in one of the in Fig. 6 shown anchor recordings 84b of the work consoles 28.

In a further step 206 , the climbing cylinders 42 are attached to one of the climbing and working consoles 26, 28 arranged in pairs in the climbing direction 20 and here, for example, at the same time vertically one above the other, provided that this has not yet been done. For this purpose, the climbing cylinders 42 are preferably pushed into the support columns 50 of the respective work consoles 28 from above.

In a further step 208 , the work platform 40 and / or the work platform 60 is attached to the work consoles 28.

In a subsequent optional step 210 , the third concrete wall section to be created can be switched on with the formwork elements of the self-climbing unit and subsequently produced using the fresh concrete method.

To implement the self-climbing unit, the work consoles 28 are detached in a further step 212 from the second anchor points 36 of the second concrete wall section 16 by removing the respective anchor bolts 30 from the anchor holes 30 of the second anchor points 36. The work consoles 28, together with the work platform 60 arranged thereon and the concrete formwork elements 58a, 58b, are now carried solely by the climbing cylinders 42, which are supported on the foot side of each of the climbing brackets 26.

In a further step 214 , the work consoles 28 are moved (raised) by means of a forward stroke movement of the climbing cylinders 42 controlled by the control device 98 of the hydraulic pump device 96 from the second anchor points 36 to the third anchor points 38 of the third concrete wall section 22 in the climbing direction 20, and the work consoles 28 by means of the Anchor bolts 30 are anchored in the anchor holes 32 of the respective third anchor points 38.

In a further step 216 , the climbing brackets 26 are released from the first anchor points 34 of the first concrete wall section 14. The climbing brackets 26 and the trailing stage 48 of the self-climbing unit 12, which may be attached to it, are held on the working brackets at this point solely by the climbing cylinders 42.

In a final step 218 , the climbing brackets 26 are moved (raised) in the climbing direction 20 by means of a return stroke movement of the climbing cylinders 42 from the first anchor points 34 of the first concrete wall section 14 to the second anchor points 36 of the second concrete wall section 16, and subsequently by means of the anchor bolts 30 into the free ones Anchor holes 32 of the second anchor points 36 of the second concrete wall section 16 are anchored.

The self-climbing unit 12 can then be used for concreting a further concrete wall section, which adjoins the third concrete wall section 22 above the third concrete wall section 22 in the climbing direction 20.
