[0042] FIG. 9 the self-climbing system according to FIG. 1 after a complete story-by-story movement of the self-climbing unit on the concrete building structure in the vertical or climbing direction in a partial sectional view;

[0043] FIG. 10 a block diagram of a self-climbing unit of FIG. 1; and

[0044] FIG. 11 a diagrammatic representation of a method for moving a self-climbing unit according to FIG. 1.

[0045] FIG. 1 shows a self-climbing system 10 having a self-climbing unit 12 that is anchored in this case to a first concrete wall section 14 and to a second concrete wall section 16 of a concrete building structure 18. First concrete wall section 14 and second concrete wall section 16 are arranged one above the other in climbing direction 20, which in this case coincides with the vertical direction, for example. It should be noted that relevant climbing direction 20, such as in the case of construction of retaining walls or the like, can be arranged obliquely to the vertical direction. In the exemplary embodiment depicted in FIG. 1, concrete building structure 18 is to be expanded upward floor-by-floor in the vertical or climbing direction 20 in fresh concrete operations. Shown above second concrete wall section 16 is a third concrete wall section 22 of structure 18 which is to be constructed and which adjoins second concrete wall section 16 in climbing direction 20.

[0046] It should be noted that concrete wall sections 14, 16, 22 of concrete building structure 12 can each have a uniform or else a respectively different (story) height 24. Concrete structure 18 may in particular be a so-called building or infrastructure core that is used for the subsequent vertical transportation or technical infrastructure of a building not shown in detail. Such infrastructure cores usually represent the static backbone of buildings and in particular can also form supports for ceilings of the building. Concrete building structure 18 may basically have a polygonal, in particular a rectangular, elliptical or circular cross-sectional shape. A freeform cross-section is also conceivable. In the case of concrete building structure 18 functioning as a building core, each concrete wall section 14, 16, 22 has two wall segments located opposite one another or is (at least partially) closed 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 concrete building structure 18.

[0047] Self-climbing unit 12 comprises according to FIG. 1 several so-called climbing brackets 26 and several so-called working brackets 28. Climbing brackets 26 are preferably of identical design. Working brackets 28 are preferably also of identical design. Climbing and working brackets may have different designs due to their different functionality.

[0048] Climbing brackets 26 are releasably anchored by anchor bolts 30 in anchor holes 32 of first anchor points 34 of first concrete wall section 14. Working brackets 28 are releasably anchored by anchor bolts 30 in anchor holes 32 of second anchor points 36 of second concrete wall section 16.

[0049] First and second anchor points 34, 36 of two concrete wall sections 14, 16 are arranged with their anchor holes 32 in vertical or climbing direction 20 in pairs to each other one above the other and are aligned to each other. In each case a third anchor point 38 of third concrete wall section 22 is arranged in alignment with its anchor holes 32 in climbing/vertical direction 20 to one of first anchor points 34 and one of second anchor points 36 of first and second concrete wall section 14, 16.

[0050] The self-climbing unit comprises an accessible first working platform 40, which is attached and supported on working brackets 26. Platform 40 is also referred to in the construction sector as so-called “Level 0”.

[0051] Self-climbing unit 12 can be moved by means of several climbing cylinders 42 without the use of a crane in vertical direction 20 along concrete wall sections 14, 16, 22. Climbing cylinders 42 may be designed in particular as hydraulic cylinders and then in the usual way each have a cylinder 44 and a fluid-actuated piston 46 guided within cylinder 44 that can be hydraulically extended from cylinder 44 and retracted into cylinder 44.

[0052] Climbing cylinders 42 are attached at one end to one of the working brackets 28 and at the other end, in this case to the free end of its piston 46, to one of climbing brackets 26 arranged underneath.

[0053] A so-called base platform 48 may be attached to climbing brackets 26. Base platform 48 is shown in FIG. 1 by a dashed line. A supporting pillar 50 may be arranged on each of working brackets 28. In this case, supporting pillars 50 preferably extend upward from associated working brackets 28, at least in sections, in vertical or climbing direction 20. A support frame 52 is attached to the upper end of supporting pillars 50. Support frame 52 includes a plurality of crossbeams 54 which are interconnected. It is understood that support frame 52 is matched in its shape and its design to the cross-sectional shape of concrete building structure 18. In the direction of a transverse axis 56, which extends orthogonally to vertical direction 20, support frame 52 protrudes outwardly in the shape of a gallows in the radial direction over first and second concrete wall sections 14, 16.

[0054] Self-climbing unit 12 is designed as a self-climbing shuttering and has a plurality of concrete shuttering elements 58a, 58b. By means of the concrete shuttering elements, third concrete wall section 22 was created by the method of fresh concrete casting. Shuttering elements 58 are attached to supporting pillar 52 and can in particular be suspended on it. In each case two of shuttering elements 58a, 58b are arranged opposite each other in the radial direction. Shuttering elements 58a, 58b are preferably mounted displaceably in the direction of transverse axis 56 on support frame 52 of self-climbing unit 12 in order to shutter the concrete wall sections to be produced in climbing direction 20 above third concrete wall section 22 and to be able to strip the shuttering again after its completion. In addition, due to the displaceable mounting of shuttering elements 58a, 58b, different wall thicknesses (=wall strengths) can be set in the respective concreting sections at minimal expense.

[0055] A working platform 60 may be arranged on support frame 52. Working platform 60 is thus arranged in the operational use of self-climbing unit 12 above working platform 40. This working platform is commonly referred to in the construction industry as “Level +1”. Working platform 60 preferably has through-holes (=discharge openings) 62 for introducing fresh concrete between shuttering elements 58a, 58b. Discharge openings 62 can be closed if necessary. Working platform 60 is provided on the edge side with a railing 64 for fall protection. Support frame 52 may be supported by additional support struts 66 on working brackets 28.

[0056] For weight reasons, supporting pillars 50 are each designed as a hollow profile and can extend downward and upward from a working platform seat 68 of respective working bracket 28 in vertical direction 20. In self-climbing unit 12 shown in FIG. 1, climbing cylinders 42 each extend in the axial direction into one of supporting pillars 50. Support columns 50 thereby function as a protective cage for climbing cylinder 42. Climbing cylinders 42 are thus largely protected against mechanical damage from the outside or from contamination.

[0057] Working brackets 28 can be moved after completion of third concrete wall section 22 by means of a synchronized feed motion of climbing cylinder 42 in climbing direction 20 of second anchor points 36 of second concrete wall section 16 to third anchor points 38 of third concrete wall portion 22 of concrete building structure 18.

[0058] In FIG. 2 an example of one of supporting pillars 50 of self-climbing unit 12 from FIG. 1 is shown. Supporting pillars 50 have a plurality of attachment points 70 for climbing cylinders 42 that are arranged along supporting pillars 50 and are spaced apart from each other. Attachment points 70 of supporting pillar 50 for climbing cylinder 42 include through-openings 72 on at least two oppositely arranged sides of the supporting pillar. Through-holes 72 are arranged in alignment to each other in pairs in the radial direction. A climbing cylinder 42 can be bolted to supporting pillar 50 via through-holes 72, meaning it can be fixed in place in the axial direction on supporting pillar 50. Climbing cylinders 42 are preferably attached at the other end to the climbing bracket, each with a small axial clearance (0.5 cm-2 cm), so that climbing cylinder 42 at respective attachment point 70 of respective supporting pillar 50 can be more easily staked/bolted.

[0059] FIG. 3 shows an exemplary embodiment of climbing bracket 26 of self-climbing unit 12 from FIG. 1 in an exposed side view and in FIG. 4 shown in a frontal view.

[0060] Climbing bracket 26 has an upper wall shoe section 74 and a lower support portion 76, each having a contact surface 78 for a respective concrete wall section 14, 16, 22 (i.e., its vertical viewing surface). Wall shoe section 74 serves to anchor climbing bracket 26 to one of respective concrete wall sections 14, 16, 22. Support section 76 essentially serves as a horizontally directed support of working bracket 28 on respective concrete wall section 14, 16, 22. Wall shoe section 74 and support section 76 are interconnected via a longitudinal profile 80. Cantilever beams 82 are used to attach the base platform or a climbing cylinder (FIG. 1).

[0061] Climbing bracket 26 has two first anchor receptacles 84a for anchor bolts 30 (FIG. 1). First anchor receptacles 84a can each be formed as through-holes of wall shoe section 74. Anchor receptacles 82 are arranged as shown in FIG. 4 on a transverse axis 88 that runs orthogonal to bracket longitudinal axis 86 and is spaced apart from it at a distance 90. The two first anchor receptacles 84a are arranged here in mirror symmetry with respect to a longitudinal center plane 92 of climbing bracket 26 that encompasses the bracket longitudinal axis and is oriented orthogonally to contact surfaces 78.

[0062] Climbing bracket 26 in the installed state on one of concrete wall sections 14, 16, 22 of concrete building structure 18 (FIG. 1) that is vertically oriented here, for example, is vertically aligned or essentially vertically aligned with its bracket longitudinal axis 84 in a manner corresponding to concrete wall sections 14, 16, 22. As a result, transverse axis 88 is arranged in the installed state of climbing bracket 26 horizontally or substantially horizontally.

[0063] FIG. 5 shows a working bracket 28 of the self-climbing unit 12 shown in FIG. 1 in an exposed side view and in FIG. 6 in an end view. Working bracket 28, in a manner corresponding to climbing brackets 26 shown in FIGS. 3 and 4, has an upper wall shoe section 74 and a bottom support section 76, each of which are provided with contact surfaces 78 for a respective concrete wall section 14, 16, 22 (i.e., its vertical viewing surface). Wall shoe section 74 and support section 76 are connected to each other purely via two longitudinal profiles 80 as an example. Cantilever beams 82 serve to support working platform 40 or one of supporting pillars 50 (FIG. 1).

[0064] Working bracket 28 has, analogously to working bracket 26, two second anchor receptacles 84b for anchor bolts 30 (FIG. 1). Second anchor receptacles 84b are arranged at a distance 90 from each other on transverse axis 88 of climbing bracket 26 that runs orthogonally to bracket longitudinal axis 86. The two second anchor receptacles 84b are arranged mirror-symmetrically with respect to a longitudinal axis 92 of climbing bracket 26 that encompasses bracket longitudinal axis 86 and is oriented orthogonally to contact surfaces 78 of climbing bracket 26. Working bracket 28 has in the assembled state on one of concrete wall sections 14, 16, 22 a bracket longitudinal axis 86 that extends in this case vertically or essentially vertically in the direction of climbing direction 20. As a result, transverse axis 88 is arranged horizontally or essentially horizontally in the installed state of climbing bracket 26.

[0065] Second anchor receptacles 84b of working brackets 28 and first anchor receptacles 84a of climbing brackets 26 correspond with one another in their pattern with respect to their relative positions on their respective wall shoe part.

[0066] In FIG. 7, first and the second concrete wall section 14, 16 and third concrete wall section 22 of concrete building structure 18 are shown after its completion (curing) in segments and together with climbing bracket 26 and working bracket 28. Climbing bracket 26 and working bracket 28 are rendered very schematically.

[0067] Anchor points 34, 36, 38 of concrete wall sections 14, 16, 22 situated one over the other each have two anchor holes 32 for anchor bolts 30 in a way corresponding to anchor receptacles 84a, 84b of working bracket 28 and climbing bracket 26 that correspond with one another in their patterns with respect to their relative positions as well as also respectively with the relative position of anchor receptacles 84a, 84b of climbing bracket 26 and working bracket 28 on wall shoe parts 74.

[0068] Thus, in each case one anchor hole 32 of anchor point 34 of first concrete wall section 14, one anchor hole 32 of second anchor point 36 of second concrete wall section 14 and one anchor hole 32 of third anchor point 38 of third concrete wall section 22 and one anchor hole of each further overlying anchor point of any further concrete wall section in climbing direction 20 are aligned with each other.

[0069] As a result, climbing bracket 26 anchored in first anchor point 34 of first concrete wall section 14 after being raised to anchor holes 32 of third anchor points 38 of third concrete wall section by a return stroke movement (=retraction of pistons 46 into cylinders 44) of climbing cylinders 42 is moved to second anchor points 36 of second concrete wall section 16 and anchored in the anchor holes 32 of second anchor points 32 of second concrete wall section 16 that are being freed.

[0070] In FIGS. 8 and 9, the self-climbing unit from FIG. 1 is shown in two successive phases of a climbing or movement process. According to FIG. 8, working brackets 28 have been released from their anchoring to second anchor points 36 of second concrete wall section 16 and moved upward to third anchor points 38 of finished (hardened) third concrete wall section 22 by means of a feed motion of climbing cylinder 42 in vertical or climbing direction 20. Working brackets 28 are anchored by means of anchor bolts 30 in anchor holes 32 of third anchor points 38. The climbing cylinders are dimensioned in such a way so that they are able to span two full story heights 24 of the concrete wall sections. A corresponding static design of the climbing cylinder is therefore indispensable.

[0071] According to the illustration of the self-climbing system in FIG. 9, climbing brackets 26 were released from their anchoring in anchor holes 30 of first anchor points 34 of first concrete wall section 14 and moved by a return stroke movement of climbing cylinders 42 to second anchor points 36 of second concrete wall section 16. Climbing brackets 26 are anchored in freed anchor holes 30 of second anchor points 36 of second concrete wall section 16 and each have two anchor bolts 30, which engage in first anchor receptacles 84a of climbing brackets 26. Concrete shuttering elements 58a, 58b of self-climbing unit 12 are then available for enclosing a further, here fourth concrete, wall section, which directly adjoins third concrete wall section 22 above third concrete wall section 22 in climbing direction 20.

[0072] In the self-climbing system according to the invention, the same anchor holes of the anchor points of concrete wall sections of a concrete building structure positioned one over the other can thus be used alternately for the working brackets and for the climbing brackets.

[0073] FIG. 10 shows a block diagram of the above-explained self-climbing unit 12. Climbing cylinders 42 are each connected via a plurality of hydraulic lines 94 to hydraulic pumping device 96. The hydraulic pumping device has control device 98 for actuating individual pumping units 99 (pumps) of hydraulic pumping device 96. Each pumping unit 99 may serve the operation of climbing cylinder 42 or, if necessary, a plurality of climbing cylinders 42. It is understood that pump units 99 in the latter case have at least one fluid valve F that is controllable by control device 98 for each climbing cylinder 42 that is fluidly connected to pumping unit 99. As a result, in this case as well, the volume flow of the hydraulic medium can be regulated individually for each individual climbing cylinder. During movement of self-climbing unit 12, which may have several dozen of the shown climbing cylinders, working brackets 28 must be positioned with their second anchor receptacles 84b or climbing brackets 16 with their first anchor receptacles 84a all as accurately as possible in front of the predetermined anchor holes 32 of respective anchor points 34, 36, 38th of respective concrete wall section 14, 16, 22. Control device 100 can therefore have a sensor 100 for each climbing cylinder 42 to detect a respective volume flow 102 of a hydraulic medium for the actuation of climbing cylinder 42. Sensors 100 may also be arranged in the housing of the control device designated as 98. On the basis of the individually detected volume flow of the hydraulic medium, each hydraulic cylinder 42 can be controlled individually by control device 98, such that the climbing cylinders are moved (are extended/retracted) exactly synchronously with one another during their actuation. Climbing cylinders 42 of self-climbing unit 12 are naturally subjected to unavoidable manufacturing tolerances and are subject to varying degrees of wear and tear. In control device 98, for each climbing cylinder 42 an individual characteristic curve 104 can therefore be stored for the dependency between a volume flow of the hydraulic medium and an associated actual length adjustment of climbing cylinder 42 per time unit. The characteristic 104 can exist, for example, in electronic form as table values or as an analytical function. It is understood that control device 98 must have a CPU (not shown) as well as suitable storage medium 106 for storing characteristic curve 104.

[0074] The above-explained self-climbing unit 12 is formed as a self-climbing shuttering unit. Self-climbing unit 12 can also be used in the construction industry without the shown concrete shuttering elements 58a, 58b, i.e. in the form of a self-climbing scaffolding unit. Concrete building structure 18 can then be, for example, a finished building core, for instance in its raw construction state.

[0075] Inventive method 200 for moving above-explained self-climbing unit 12 will be explained below with reference to FIG. 11. In first step 202, climbing brackets 26 are anchored with anchor bolts 30 in anchor holes 32 of first anchor points 34 of first concrete wall section 14.

[0076] Each anchor bolt 30 engages in one of second anchor receptacles 84b of climbing brackets 26.

[0077] In further step 204, working brackets 28 are anchored with anchor bolts 30 in anchor holes 32 of second anchor points 36 of second concrete wall section 16. Anchor bolts 30 in each case engage in one of anchor receptacles 84b of working brackets 28 shown in FIG. 6.

[0078] In further step 206, climbing cylinders 42 are attached to each one of the climbing and working brackets 26, 28 arranged in pairs in climbing direction 20 and in this case, for example, also vertically one over the other, if this has not yet been done. Climbing cylinders 42 are preferably inserted from above into supporting pillars 50 of respective working brackets 28.

[0079] In a further step 208, working platform 40 and/or working platform 60 is attached to working brackets 28.

[0080] In subsequent optional step 210, the third concrete wall section to be constructed can be shuttered with the shuttering elements of the self-climbing unit and subsequently produced via the fresh concrete method.

[0081] To move the self-climbing unit, working brackets 28 are released in further step 212 from second anchor points 36 of second concrete wall section 16 by the respective anchor bolts 30 being removed from anchor holes 30 of second anchor points 36. Working brackets 28, along with working platform 60 arranged on them and concrete shuttering elements 58a, 58b, are now carried solely by climbing cylinders 42, which are supported at the base on at least one of climbing brackets 26.

[0082] In further step 214, working brackets 28 are moved (raised) by means of a controlled feed motion which is actuated by controlling device 98 of hydraulic pumping device 96 of climbing cylinder 42 from second anchor points 36 to third anchor points 38 of third concrete wall section 22 in climbing direction 20, and working brackets 28 are anchored in anchor holes 32 of respective third anchor points 38 by means of anchor bolt 30.
