Definitions
- 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.
- 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.
- 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.
- 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.
- the number of anchor points and therefore the concrete wall anchor should also be kept as low as possible for cost reasons.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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 .
- the anchor holes of at least part of the anchor points are used both for anchoring the work and climbing brackets.
- 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.
- 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.
- 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.
- 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.
- 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.
- the aforementioned concrete formwork elements in particular suspended. This means that small and large storey heights can be realized.
- the support columns are each designed as a hollow profile. This allows the weight of the self-climbing unit to be minimized.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the climbing cylinders used in the construction sector are also subject to inevitable manufacturing tolerances.
- this can be compensated for by the volume flow-based control of the climbing cylinders.
- 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 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.
- 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.
- 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).

- 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 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.
