The present application claims priority to the filing of German patent application number 10 2020 134 812.6 filed on Dec. 23, 2020, this disclosure of which is hereby incorporated by reference.
The invention relates to a climbing shoe device fora rail-guided climbing system which can be used in particular as a climbing formwork, climbing frame, climbing protective wall, and/or climbing working platform, comprising a shoe base body, at least one rail guide element coupled to the shoe base body and first and second latching/snap-action elements. The invention further relates to a rail-guided climbing system comprising said climbing shoe device and a method for climbing a rail-guided climbing system which can be used in particular as a climbing formwork, climbing frame, climbing protective wall, and/or a climbing working platform, in which the climbing shoe device is arranged in a stationary manner on a structure.
In construction, climbing systems are used, e.g., in the construction of vertically oriented concrete structures, in particular so-called building cores, bridges, dams, and the like, as climbing formwork and/or climbing protective walls and/or in the form of climbing frames. The climbing systems are usually provided with a working platform as a frame unit and can be moved independently of a crane from a lower finished concrete wall portion of the concrete structure to be constructed or finished to a further hardened concreting portion of the concrete structure arranged above. In rail-guided climbing systems, a climbing shoe with a controllable latch is usually installed for each anchor point. In order to climb with climbing systems, a holding point and a climbing point are always required, as is described, for example, in connection with the climbing shoe, which is described in DE 10 2005 030 333 A1. In many current climbing systems, the second climbing point necessary for climbing is formed in the operating state by installing a mobile climbing mechanism cylinder on the climbing shoe. The climbing mechanism cylinder has, on the end opposite the climbing shoe, a latch for holding a climbing rail and thus forms the second climbing point. A functioning climbing system is only possible through the alternating interaction of a climbing point, formed by the climbing mechanism cylinder between the climbing shoe and climbing rail sockets, and a holding point, formed by a climbing shoe latch and a climbing rail socket. In addition to the known climbing rail, there can be a climbing lift rail, also called a climbing saw, installed in this climbing rail. In the case of the climbing lift rail installed in the climbing rail, two anchor points or climbing shoes are always required for climbing the system. By alternately holding and climbing/lifting between the two climbing shoes used, the system can climb, as described, for example, in DE 1020 18 117 727 A1. The climbing lift rail presses the entire climbing system upward via a lower climbing shoe until the climbing cylinder is completely extended. The climbing cylinder is then retracted. The socket of the climbing rail latches on the upper climbing shoe after a short downward movement. The climbing system therefore hangs on the upper climbing shoe, as a result of which the load is held by the upper climbing shoe. The climbing cylinder retracts and “pulls” the climbing lift rail at the lower, now load-free climbing shoe “past” so that the climbing lift rail can be pulled along in order to carry out the next stroke.
A disadvantage is that, in the case of the climbing systems which are usually used on the market, which work with a mobile climbing work cylinder, a conversion of the climbing work cylinders into the finished floor plane is necessary in order to reach the next floor section to be produced. The implementation of large, heavy components, such as the mobile climbing work cylinder(s), is carried out by the worker and is ergonomically very complex. Furthermore, there is a risk of falling components. In the case of systems with non-mobile climbing mechanism cylinders, which therefore do not have to be dismantled and implemented, a preliminary climbing of the climbing rail is necessary, which is highly disadvantageous and time-consuming. In order to operate a climbing mechanism system having a climbing lift rail integrated in the climbing rail, it is also necessary for two climbing shoes to be connected to two anchor points to be always available for climbing. This is necessary to provide a holding point in the form of a first climbing shoe and a climbing point in the form of a second climbing shoe on which the system climbs up. In this case, one must also check, on both anchor planes, that is to say where the first and second climbing shoes are each located, whether the two climbing shoes are correctly connected.
In contrast, the object of the present invention is to provide a simple and compact climbing shoe device with which the disadvantages of the prior art are avoided. In particular, it is intended to enable the climbing shoe device to reduce the effort that is associated with the fact that one must check, on both anchor planes, that is to say where the first and second climbing shoes are each located, whether the two climbing shoes are correctly connected. In addition, the climbing shoe device is to be provided in such a way that it is possible to climb continuously step-by-step without the previously required high manual effort after each lifting process.
This object is achieved by a climbing shoe device and a method for climbing a rail-guided climbing system.
The invention relates to a climbing shoe device fora rail-guided climbing system which can be used, in particular, as a climbing formwork, climbing frame, climbing protective wall, and/or a climbing working platform. The climbing shoe device which can be arranged in a stationary manner on a structure comprises a shoe base body, at least one rail guide element that is coupled to the shoe base body and is designed such that, in a guide position of the rail guide element, a first climbing shoe rail and a second climbing shoe rail, which, by means of a lifting device, are connected to one another and can be moved relative to one another, can be guided directly or indirectly from the climbing shoe device relative to the shoe base body, and first and second latching/snap-action elements. The first and second latching/snap-action elements are each designed such that, in a hooked-in position pivoted-out and/or extended relative to the shoe base body, the first climbing shoe rail can be hooked by the first latching/snap-action element and the second climbing shoe rail by the second latching/snap-action element into the climbing shoe device counter to a direction and, in a traversed position pivoted-in and/or retracted relative to the shoe base body, the first latching/snap-action element can be traversed by the first climbing shoe rail and the second latching/snap-action element can by the second climbing shoe rail in the direction. The first and second latching/snap-action elements are coupled to the shoe base body in each case so as to be displaceable between the hooked-in position and the traversed position in such a way that, when the first or second latching/snap-action element is in the hooked-in position, the other of the first and second latching/snap-action elements can be in the traversed position, the hooked-in position, or a position in between.
The climbing shoe device can be formed integrally as a climbing shoe or assembled into a climbing shoe device made up of several parts. The shoe base body can be designed as a frame, wherein a formation as a flat body with or recesses is possible. The shoe base body can consist of one or more parts/components which are detachably connected, that is reversibly, or irreversibly, to one another. The parts or components of the shoe base body can be manufactured from different materials, for example steel, aluminum, or carbon fiber composite materials, or a combination thereof, in order to keep the weight of the shoe base body and thus of the climbing shoe device low. The first and second climbing shoe rails can be identical or different from one another.
In addition to the one rail guide element, a further rail guide element can be coupled to the shoe base body, wherein at least the one rail guide element, in particular the one rail guide element and the further rail guide element, are arranged on the shoe base body so as to be pivotable and/or extendable in such a way that, in a pivoted and/or extended guide position, that is to say in the “closed” position, the first and second climbing shoe rails are guided by the rail guide elements by portions of the first and/or second climbing shoe rails being enveloped by the rail guide elements. It is possible for the first and second climbing shoe rails to be guided only by the one rail guide element in the “closed” position by portions of the first and/or second climbing shoe rails being enveloped by the rail guide element. If the second climbing shoe rail is guided displaceably from the first climbing shoe rail with respect to the first climbing shoe rail and portions of the first climbing shoe rail are enveloped by the rail guide element, portions of the second climbing shoe rail are also enveloped by the rail guide element, and therefore the second climbing shoe rail is also guided by the rail guide element in addition to the first climbing shoe rail. Therefore, one or both of the first and second climbing shoe rails can be guided indirectly by the rail guide element(s). In addition to the “closed” position, there can be an “open” position, in which the one rail guide element and/or the further rail guide element is/are in an unpivoted or pivoted-in and/or retracted position relative to the shoe base body. In the “open” position, one or both of the first and second climbing shoe rails can be released from the guidance of the climbing shoe device or the climbing shoe device can be removed between the structure and the first and second climbing shoe rails, for example by pulling in or counter to a climbing direction.
The first and second latching/snap-action elements can be formed identically or differently from one another and can each be coupled by means of a linear, that is translational, movement in the form of a retraction or extension and/or a rotational movement in the form of a pivoting in or out on the shoe base body. The direction for traversing the first and/or second latching/snap-action element can be a vertical or horizontal direction or a direction which is inclined, linear, or curved relative to the direction of gravity, in particular a climbing direction. The first and second climbing shoe rails can each have bulges and/or cutouts in order to be able to interact with the first and second latching/snap-action elements, respectively.
If the first latching/snap-action element is in the hooked-in position, the second latching/snap-action element is designed such that it can be in the traversed position, the hooked-in position, or a position in between, that is to say in any of its possible positions. Conversely, if the second latching/snap-action element is in the hooked-in position, the first latching/snap-action element is designed such that it can be in the traversed position, the hooked-in position, or a position in between, that is to say in any of its possible positions. Therefore, for the other of the first and second latching/snap-action elements, which is not in the hooked-in position, no locking occurs in one of its possible positions. Instead, this other element of the first and second latching/snap-action elements, which is not in the hooked-in position is unlocked. The first or second latching/snap-action element which is in the hooked-in position can be locked in its hooked-in position when the other of the first and second latching/snap-action elements is in any of its possible positions. The two latching/snap-action elements can thus be coupled in such a way that the first or second latching/snap-action element is locked in the hooked-in position when the other of the first and second latching/snap-action elements can be in the traversed position, the hooked-in position, or a position in between. The coupling, after which one of the first and second latching/snap-action elements is locked in the hooked-in position when the other of the first and second latching/snap-action elements is unlocked, can switch between the first and second latching/snap-action elements one after the other. It is therefore possible that, when the first latching/snap-action element is locked in the hooked-in position, the second latching/snap-action element is unlocked, and then, when the second latching/snap-action element is locked in the hooked-in position, the first latching/snap-action element is unlocked. Alternatively, the two latching/snap-action elements can be brought into each of their possible positions independently of one another so that, when the first or second latching/snap-action element is in the hooked-in position, the other of the first and second latching/snap-action elements can be in the traversed position, the hooked-in position, or a position in between. According to the invention, therefore, the possibility that, when one of the first and second latching/snap-action elements is in the hooked-in position, the other of the first and second latching/snap-action elements must be in the hooked-in position, the traversed position, or a position in between is excluded. There is no exclusivity for the pivoted-in and/or retracted traversed position with respect to the traversal, wherein positions between the hooked-in position and the traversed position can be traversed. One or both of the first and second latching/snap-action elements can be coupled to the shoe base body so as to be pivotable and/or retractable and extendable, for example by means of a spring element or actively controllable, such that the respective latching/snap-action element can be traversed in a position between the hooked-in position and the traversed position from the first or second climbing shoe rail. In this respect, the term traversed position serves merely to demarcate from the hooked-in position, that is to say to define both end positions of the first or second latching/snap-action element.
The first or second latch/snap-action element that is in the hooked-in position forms, together with the first or second climbing shoe rail hooked into this latching/snap-action element, the holding point. The other of the first and second latching/snap-action elements, which is in the traversed position, the hooked-in position, or a position in between, forms the climbing point when it is traversed by the other of the first or second climbing shoe rails. It is thus possible to combine the holding point and the climbing point on an anchor plane, that is at an anchor point. By eliminating the second anchor plane, it is possible in a simple manner to check whether both latching/snap-action elements are correctly connected. The previously complex check as to whether both climbing shoes are correctly connected can be done away with due to the discontinuation of the distancing of both climbing shoes away from one another. Instead, the holding and climbing points are combined in only one climbing shoe device. Climbing a climbing system which is hooked into the climbing shoe device according to the invention at only one anchor point is possible, wherein the lifting device is carried along by both climbing shoe rails during climbing and does not have to be moved separately. In addition, the climbing shoe device is of simple and compact design, since only two latching/snap-action elements that are movable relative to one another are to be provided. As a result of the double latching/snap-action elements, for example in the form of double latches, or twice the holding possibility for the climbing shoe rails on the climbing shoe device or on a bracket or anchor point on which the climbing shoe device is arranged in a stationary manner, a climbing process that works on only one anchor location can be achieved. The double holding possibility is achieved by designing the climbing shoe with a latching/snap-action element for holding a climbing rail such that, in addition to this holding possibility for a climbing shoe rail in the form of a climbing lift rail, the climbing shoe also has the second holding possibility for holding the second climbing shoe rail in the form of a second latching/snap-action element (either for a climbing rail or for a second climbing lift rail).
For developments in climbing mechanisms in the form of lifting devices which are integrated in a climbing rail or are at least connected to one of the two climbing shoe rails and do not have to be implemented by hand, several advantages result from double latching/snap-action elements on the climbing shoe devices:
In a preferred embodiment, the climbing shoe device comprises a first climbing shoe part with a first shoe base body part and a second climbing shoe part with a second shoe base body part. The first climbing shoe part comprises the rail guide element and additionally comprises the first or second latching/snap-action element, and the second climbing shoe part comprises the other of the first and second latching/snap-action elements, wherein the first and second climbing shoe parts are reversibly detachably connected to one another in such a way that they can be arranged on the structure together as a climbing shoe device on the same anchor point. In this way, a conventional climbing shoe, which comprises, as the first climbing shoe part, the rail guide element and the first or second latching/snap-action element, can be supplemented with an additional component, which comprises, as the second climbing shoe part, the other of the first and second latching/snap-action elements, to form the climbing shoe device according to the invention. The additional component can be placed “piggy-back style” on the conventional climbing shoe and reversibly connected thereto or reversibly attached thereto below the conventional climbing shoe. This allows an existing climbing shoe to be simply and cost-effectively retrofitted to the climbing shoe device according to the invention. Therefore, the possibility that the second holding option in the form of the other of the first and second latching/snap-action elements is realized as an additional component on a standard climbing shoe is not excluded. As a result, the standard climbing shoe takes on the additional component “piggy-back style,” as a result of which the climbing shoe device according to the invention is produced with the two holding possibilities, which, however, are slightly offset from one another. However, the double holding possibility for the first and second climbing shoe rails at only one anchor point is maintained, since the “piggy-back additional component” does not have to be separately anchored but can be placed on the anchored climbing shoe.
Particularly preferably, the first climbing shoe part comprises rail guide elements and the second climbing shoe part comprises at least one further rail guide element. In this way, the additional component for guiding the two climbing shoe rails can also be used, which increases safety when the first or second climbing shoe rail is being hooked into and out of the additional component. The guidance can take place by portions of the first and/or second climbing shoe rails being clasped by the further rail guide element.
In the case of a lifting device that is permanently connected to the climbing shoe rail and, after an executed stroke, must not be separated from the climbing shoe rail and must be moved by hand, a second holding possibility for one of the climbing shoe rails is realized by mounting the second climbing shoe part as a second climbing shoe on a conventional climbing shoe, for example in the form of a “piggy-back climbing shoe,” which can guide at least one of the two climbing shoe rails and into which one of these rails can be hooked. As a result of the possibility of additional mounting and dismounting of the second climbing shoe part onto and from a conventional climbing shoe, which can be arranged in a stationary manner at any anchor point, a flexible selection of the anchor point is possible in order to additionally introduce the climbing point with the holding point and consequently the forces occurring on the climbing system into the structure via an anchor point.
The second climbing shoe part advantageously comprises first and secand further rail guide elements, wherein at least the first further rail guide element, in particular the first and second further rail guide elements, is/are arranged on the second basic shoe body part so as to be pivotable and/or extendable in such a way that, in the pivoted and/or extended guide state, the first and second climbing shoe rails arranged displaceably between the first and second further rail guide elements are guided by the further rail guide elements by portions of the first and second climbing shoe rails being enveloped by the further rail guide elements, and a displacement element provided with a handle. The displacement element is designed such that it is mechanically coupled to the second shoe base body part and the first further rail guide element, and, when the first further rail guide element is in the guide state, a displacement of the displacement element in a decoupling direction relative to the second shoe base body part produced by actuating the handle results in the first further rail guide element being shifted into the non-pivoted and/or retracted initial state in order to release the second climbing shoe part from a guidance of the first and second climbing shoe rails.
The second climbing shoe part therefore has a handle on the displacement element, with the actuation of which the second climbing shoe part, when the displacement of the displacement element relative to the second shoe base body part produced by actuating the handle occurs in the decoupling direction, can be separated in a simple manner from the first climbing shoe part and the first and/or second climbing shoe rails can be released from the guidance. The second climbing shoe part on the handle can preferably be recoupled with the first climbing shoe part, when the displacement of the displacement element relative to the second shoe base body part produced by actuating the handle occurs in the coupling direction counter to the decoupling direction. By actuating the handle, for example by means of a pulling movement, that is “pulling,” the further rail guide elements, which engage around the first and/or second climbing shoe rails for guiding, open.
The first latching/snap-action element can comprise a first latch and the second latching/snap-action element can comprise a second latch, wherein, when the first and second climbing shoe rails are guided by the climbing shoe device, the first latch is arranged next to the second latch, substantially on an axis perpendicular to a longitudinal axis of the first climbing shoe rail or the second climbing shoe rail. This allows for a compact design of the climbing shoe device.
The second latching/snap-action element preferably comprises two second latches and, when the first and second climbing shoe rails are guided by the climbing shoe device, the first latch is arranged between the two second latches, in particular at the same distances of the first latch to the two second latches, on the axis perpendicular to the longitudinal axis of the first climbing shoe rail or the second climbing shoe rail. If the climbing direction points vertically upward, the two second latches are arranged substantially horizontally at a distance from the longitudinal axis. In this way, the climbing shoe device can divert a load of the first and second climbing shoe rails into the wall or the ceiling which is higher than a load that is only received by one or two latches when the first and/or second climbing shoe rail is hooked in. The symmetrical orientation of the two second latches relative to the longitudinal axis simplifies the design of the climbing shoe device. In addition, the load capacity of the climbing shoe device is optimized with a symmetrical alignment of the two second latches to the longitudinal axis.
Particularly preferably, the first latching/snap-action element comprises two first latches and the second latching/snap-action element comprises two second latches. When the first and second climbing shoe rails are guided by the climbing shoe device and a longitudinal axis of the climbing shoe is oriented in a climbing direction, the two first latches of the first latching/snap-action element are arranged on a first axis substantially perpendicular to the longitudinal axis and at a distance from the longitudinal axis, in particular at substantially equal distances from the longitudinal axis, and the two second latches of the second latching/snap-action element are arranged on a second axis substantially perpendicular to the longitudinal axis and at a distance from the longitudinal axis, in particular at substantially equal distances from the longitudinal axis, in or counter to the climbing direction thereof or at the same height in the climbing direction. Due to the distribution of the load on two latches of the first and second latching/snap-action elements respectively, wherein the two first and two second latches can be actuated in pairs, the permissible load can be higher than in one embodiment in which the first and/or second latching/snap-action element each have only one latch. In order to keep the structural form perpendicular to the longitudinal axis of the climbing shoe compact, the two first latches of the first latching/snap-action element can be arranged so as to be offset relative to the two second latches of the second latching/snap-action element in or counter to the climbing direction.
Depending on the design of the first and second climbing shoe rails, it can be advantageous to arrange the two first latches of the first latching/snap-action element on the first axis substantially perpendicular to the longitudinal axis and at a distance from the longitudinal axis at substantially the same first distances from the longitudinal axis and, arranged at a distance therefrom in or counter to the climbing direction thereof or at the same height in the climbing direction, the two second latches of the second latching/snap-action element on the second axis substantially perpendicular to the longitudinal axis and at a distance from the longitudinal axis at substantially the same second distances from the longitudinal axis, wherein the first and second distances differ from one another, in particular the first distances are selected to be smaller than the second distances.
It serves the purpose of safety during climbing when, as already mentioned, the first and second latching/snap-action elements are coupled to one another in such a way that, when the first or second latching/snap-action element can be in the traversed position, the hooked-in position, or a position in between, the other of the first and second latching/snap-action elements is locked in the hooked-in position. The coupling of the two latching/snap-action elements can occur mechanically, for example by a locking element, by means of which the movement of the first or second latching/snap-action element is limited in each case. The locking element can be arranged tiltably and/or displaceably between the two latching/snap-action elements for engagement in one of the latching/snap-action elements. Motorized coupling by means of a controllable actuating element for limiting movement of the first or second latching/snap-action element is also conceivable. Thus, the tilting movement and/or the displacement movement of the locking element can be performed in a motorized manner, for example by means of an electric motor. It is also possible to unlock the motorized coupling manually by means of a switch or a software command.
The invention also comprises a rail-guided climbing system with the climbing shoe device according to the invention and the first and second climbing shoe rails. In a particularly advantageous embodiment, climbing shoe devices are provided in a climbing direction or counter to the climbing direction only for guiding the first climbing shoe rail and/or second climbing shoe rail, but not for engaging the first and second climbing shoe rails. In this way, the holding point and the climbing point are combined in only one climbing shoe device, which simplifies the process of checking whether the first and second latching/snap-action elements are connected correctly.
A simple rail-guided climbing system is present when either the first climbing shoe rail is designed as a climbing rail which can be integrated into a frame unit or can be fastened to the frame unit, and the second climbing shoe rail is designed as a climbing lift rail which is displaceable relative to the climbing rail and guided by the climbing rail or the first climbing shoe rail is designed as a climbing lift rail and the second climbing shoe rail as a climbing rail. It is now possible for the climbing shoe to hold both the climbing rail and the climbing lift rail. A latching/snap-action element, for example in the form of a latch, always operates with the climbing rail, and the other latching/snap-action element, for example in the form of a further latch, always operates with the climbing lift rail.
The rail-guided climbing system is particularly advantageous when the first climbing shoe rail is designed as a first climbing lift rail and the second climbing shoe rail is designed as a second climbing lift rail and a climbing guide rail is additionally provided which can be integrated into a frame unit or can be fastened to the frame unit, wherein the first and second climbing lift rails are guided displaceably from the climbing guide rail relative to the climbing guide rail and, by means of the lifting device, are connected to one another and are coupled to the climbing guide rail. In this way, when the first and second climbing lift rails are synchronized with one another and are each displaced relative to the climbing guide rail by means of the lifting device, a climbing system can be achieved in which the climbing guide rail can be continuously climbed with the frame unit relative to the climbing shoe device arranged in a stationary manner. This serves the purpose of safety in the climbing process. It is now possible for the climbing shoe device to hold both alternately operating climbing lift rails. If the one climbing lift rail is pushed upward by means of the lifting device, the climbing guide rail is pulled along. The climbing guide rail is no longer held by the climbing shoe device but is only guided via the at least one rail guide element, also called a “lug”. This allows for a continuously operating climbing process for the climbing guide rail relative to the climbing shoe device. The above-described “piggyback climbing shoe device” can be applied for both variants of climbing shoe rails, that is both for the first variant in which the first climbing shoe rail is designed as a climbing rail and the second climbing shoe rail as a climbing lift rail, and also for the second variant in which the first climbing shoe rail is designed as a first climbing lift rail and the second climbing shoe rail is designed as a second climbing lift rail and, additionally, the climbing guide rail is provided, wherein the first and second climbing lift rails are guided displaceably from the climbing guide rail relative to the climbing guide rail and, by means of the lifting device, are connected to one another and coupled to the climbing guide rail.
The climbing lift rails can each form a unit. The one climbing lift rail can be arranged in parallel with the other climbing lift rail and within/centrally from the other climbing lift rail. Alternatively, however, it is also conceivable for the two climbing lift rails to be designed and arranged differently, for example that the two climbing lift rails run next to one another, for example perpendicularly to a climbing direction, and not the one inside the other. Embodiments in which more than two climbing lift rails are arranged are also conceivable. An advantage of such an embodiment is that a smaller lift is necessary per climbing lift rail in order to climb a given distance than is necessary if only two climbing lift rails are present. In the case of a given stroke length and a lifting process, the climbable distance is thus produced as the number of climbing lift rails multiplied by the stroke length.
Advantageously, holding elements in the form of holding recesses are introduced into the climbing lift rail or in the first climbing lift rail and/or the second climbing lift rail one behind the other, or holding knobs are applied, for example welded, either to the climbing lift rail or to the first climbing lift rail and/or the second climbing lift rail for engagement in the first and/or second latching/snap-action element of the climbing shoe device. The climbing lift rail has the retaining recesses on at least one side in such a way that the climbing lift rail is present in the form of a profile with an engaging contour, in particular with teeth. It is also possible for the climbing lift rail to have the retaining recesses in the form of completely outlined holes, also called ears, which have a higher load-bearing capacity than the retaining recesses of the engaging contour which are not completely outlined.
In the climbing system with two climbing lift rails and a climbing guide rail, the lifting device can advantageously comprise a first lifting cylinder as the first lifting device part and a second lifting cylinder as a second lifting device part, wherein the first lifting cylinder is connected in its first end region to the first climbing lift rail and in its second end region to the climbing guide rail and the second lifting cylinder is connected in its first end region to the second climbing lift rail and in its second end region to the climbing guide rail. In this way, the climbing guide rail, with which the two lifting device parts are connected to one end region respectively, can be continuously climbed in a movement of the climbing system by means of the two lifting device parts. The two lifting device parts can be coupled to one another on the control side in such a way that only one of the two lifting device parts is in operation in order to ensure a continuous movement of the climbing guide rail relative to the climbing shoe device. Alternatively, the two lifting device parts can be coupled to one another such that lifting movements of the two lifting device parts take place simultaneously and in opposite directions to one another in order to ensure a continuous movement of the climbing guide rail relative to the climbing shoe device.
The first and second lifting cylinders can be designed pneumatically or hydraulically, for example filled with oil. In the case of hydraulic lifting cylinders, the two lifting cylinders can be connected to one another via a common oil line in order to share a common oil reservoir. When a first piston of the first lifting cylinder is completely retracted, a first cylinder chamber of the first lifting cylinder is completely filled and a second piston of the second lifting cylinder is completely extended such that no oil is located in a second cylinder chamber of the second lifting cylinder. All of the oil is then located in the first cylinder chamber of the first lifting cylinder, which keeps the first piston of the first lifting cylinder completely retracted. Two valves can be arranged at each of the first and second pistons, wherein a first valve operates when the piston is fully retracted and a second valve operates when the piston is fully extended. The oil flow from the first cylinder chamber into the second cylinder chamber and vice versa can be controlled by means of the first and second valves. The two lifting cylinders are thus coupled via the common oil reservoir such that simultaneous and counter-rotating lifting movements of the two lifting cylinders can be carried out in a simple manner. The amount of the oil in the common oil reservoir remains constant, wherein, depending on the position of the pistons of the two lifting cylinders, the amount of the oil is distributed to both cylinder spaces of the two lifting cylinders.
Alternatively, the lifting device can be designed as a crankshaft drive with a rotary motor, in particular an electric motor, for driving the crankshaft, wherein a first end region of a crank of the crankshaft is rotatably coupled to the first climbing lift rail, a second end region of the crank is rotatably coupled to the second climbing lift rail, and the rotary motor in which the crankshaft is rotatably mounted is connected to the climbing guide rail. Any motor that can drive an axis in at least one direction of rotation is considered to be a rotary motor. In this way, a continuous movement of the climbing guide rail relative to the climbing shoe device can be ensured when the crankshaft is rotated by the rotary motor. In addition, the design of the lifting device is simple because only one motor of the two climbing lift rails can be displaced with respect to the climbing shoe device.
The invention also comprises a method for climbing a rail-guided climbing system which can be used in particular as a climbing formwork, climbing frame, climbing protection wall, and/or climbing working platform. The method comprises the following steps:
The effects and advantages of this method according to the invention for climbing a rail-guided climbing system correspond to those of the above-described climbing shoe device according to the invention for a rail-guided climbing system.
In a preferred embodiment, the first climbing shoe rail is designed as a climbing rail which is integrated into a frame unit or is fastened to the frame unit, and the second climbing shoe rail is designed as a climbing lift rail which is displaced relative to the climbing rail and guided by the climbing rail in order to achieve a simply constructed and cost-effective method for climbing, in which the holding and climbing point are combined in a climbing shoe device.
Alternatively, the first climbing shoe rail can be designed as a first climbing lift rail and the second climbing shoe rail can be designed as a second climbing lift rail and, in addition, a climbing guide rail can be provided which is integrated in a frame unit or fastened to the frame unit, wherein the first and second climbing lift rails are displaced relative to the climbing guide rail and guided by the climbing guide rail and, by means of the lifting device, are connected to one another and coupled to the climbing guide rail.
The method for climbing can proceed as follows:
The embodiment of the first and second climbing shoe rails as climbing lift rails together with the climbing guide rail makes it possible to continuously displace the climbing rail guide relative to the climbing shoe device when the first and second climbing lift rails are synchronized with one another and each displaced by means of the lifting device in such a way. This serves the purpose of safety in the climbing process.
The two climbing lift rails can therefore be driven by the lifting device as a drive system such that the climbing lift rails move in opposite directions to one another, for example up and down in a building or sideways in a tunnel construction. For example, if the one climbing lift rail is pushed downward by the drive system, the other climbing lift rail is pushed upward. The movement can be realized by various drive systems, such as, for example, two lifting cylinders as first and second lifting device parts, wherein each cylinder is coupled to a climbing lift rail. Alternatively, instead of two lifting cylinders, a rotary drive system can also be used, which connects the two climbing lift rails via a crankshaft drive with rotary motor, for example with an eccentrically arranged fastening point in each case of an end region of the two climbing thrust rails.
The method steps for climbing the rail-guided climbing system according to the invention are preferably defined as a cycle, wherein the cycle is repeated until the frame unit has reached a further or a plurality of further floors of the structure or a concreting section of the structure to be concreted.
Further features and advantages of the invention will become apparent from the following detailed description of an embodiment of the invention, from the patent claims and from the figures of the drawings, which show details essential to the invention. The features shown in the drawings are depicted in such a way that the special features according to the invention can be made clearly visible. The different features can each be realized in isolation or as a plurality in any combination in variants of the invention. In the figures, the same reference signs denote the same or corresponding elements.
In the drawings:
The state of the climbing shoe 1 in the “closed” position of the rail guide elements 3a, 3b coupled to the climbing rail 9 with the climbing lift rail 9b is shown in
In
In contrast to the arrangement of the climbing rail 9 relative to the climbing shoe 1 according to
In
By actuating the handle 7 in the decoupling direction, for example in the Z direction, the climbing shoe 1 can be shifted into the state in which the rail guide elements 3a, 3b and the latching/snap-action elements 10, 10′, 10″ are each in their initial state, that is to say in the traversed position or “open” position. This is possible since the displacement element 6 is arranged so as to be displaceable relative to the shoe base body 2 and is mechanically coupled to the shoe base body 2, the rail guide elements 3a, 3b, and the latching/snap-action elements 10, 10′, 10″, and, when the rail guide elements 3a, 3b are in the guide state and the latching/snap-action elements 10, 10′, 10″ are in the pivoted holding state, a displacement of the displacement element 6 relative to the shoe base body 2 produced by actuating the handle 7 results in the rail guide elements 3a, 3b and the latching/snap-action elements 10, 10′, 10″ each being shifted into the non-pivoted initial state, that is to say into the “open” position, in order to decouple the climbing shoe 1 from a bracket element and/or from the climbing lifting rail 9b and to release it from the guidance of the climbing rail 9 and/or the climbing lifting rail 9b. The climbing shoe can have a receiving element 5 which is arranged on the shoe base body 2 and is designed to interact with a first portion of the bracket element arranged in a stationary manner on a concreting portion of a structure such that, when the receiving element 5 abuts the first portion of the bracket element, a load of the climbing shoe 1 can be introduced into the bracket element.

The first and second climbing lift rails 9a′, 913′ are arranged inside a climbing guide rail 9′, which comprises outer climbing guide rail outer elements 9′1, 9′2. No direct holding function takes place with the climbing guide rail 9′ with respect to hooking into a latching/snap-action element of the climbing shoe and it consequently serves to receive and guide the climbing lift rails 9a′, 913′, which are connected to the climbing guide rail 9′ by a lifting device (not shown). The climbing lift rails 9a′, 913′ and lifting device form a climbing mechanism. In addition, a frame unit, for example, that can comprise platforms and formwork is fastened to the climbing guide rail 9′.
With the same distance of the inner sides of the climbing rail outer elements 9a1, 9a2 from one another and the inner sides of the climbing guide rail outer elements 9′1, 9′2 from one another, the second latches 10′, 10″ are further together relative to the first latch 10 than in the first embodiment of the climbing shoe 1 shown in
The climbing shoe 1 comprises rail guide elements 3a, 3b pivotably coupled to the shoe base body 2 which are in the “closed” position in order to envelop sections of the climbing guide rail outer elements 9′1, 9′2 facing the climbing shoe 1 in order to guide the climbing guide rail 9′ and the first and second climbing lift rails 9a′, 913′ coupled thereto via the lifting device. In this guide position of the rail guide elements 3a, 3b, the moving element 6, which is provided with the handle 7 and mechanically coupled to the shoe base body 2 and the rail guide element 3a, 3b, is inserted in the coupling direction, which corresponds to the negative Z direction, relative to the shoe base body.
In
The climbing shoe is in a state when the handle 7 is not actuated, that is to say in the “closed” position, with the finger grip 13 not actuated in the unlocking direction in the Z direction. The latching/snap-action element 10′ is therefore in a hooked-in position, that is in the holding state, wherein a pressure is exerted on the locking element 4 via an upper bearing surface of the locking element by means of a spring element (not shown). The finger displacement element 12 is not latched into a central axle element 2c (latching recess of the finger displacement element 12 for the central axis element 2c not shown). The handle 7 is not actuated in the decoupling direction in the Z direction and the latching/snap-action element 10′ engages in a holding element of the second climbing lift rail 9b′1.
The two latches 10a, 10b are each rotatably mounted in an end region facing the shoe base body 2 by means of a latch axle element which forms a part of the shoe base body 2. The mounting takes place such that the first latching snap-action element in the form of the first latch 10a interacts only with the first climbing lift rail 9a″ and the second latching snap-action element in the form of the second latch 10b only interacts with the second climbing lift rail 9b″. Therefore, the first latch 10a can be coupled via a first spring element (not shown) and the second latch 10b via a second spring element (not shown) to the latch axis element so that when the first latch is in the hooked-in position, the second latch 10b can be in the traversed position, the hooked-in position, or a position in between, and vice versa. The latching snap-action element elements 10a, 10b are shown in simplified form.

The second climbing shoe part 1b has a displacement element which is mechanically coupled to the second shoe base body part 2a and has a handle 7. The mode of operation of the second climbing shoe part 1b corresponds to that which is described in connection with the climbing shoes 1 in each case, which are shown in
At substantially equal distances from the longitudinal axis L, the two first latches 101, 102 of the first latching/snap-action element are at a distance from the longitudinal axis L substantially on a first axis substantially perpendicular to the longitudinal axis L of the climbing shoe. Counter to the climbing direction, which is directed vertically upward, the two second latches 10′, 10″ of the second latching/snap-action element are arranged so as to be at a distance from the two first latches 101, 102 on a second axis substantially perpendicularly to the longitudinal axis L at a distance from the longitudinal axis L at substantially equal distances from the longitudinal axis L. The two first latches 101, 102 of the first latching/snap-action element and the two second latches 10′, 10″ of the second latching/snap-action element can be actuated in pairs. To keep the design perpendicular to the longitudinal axis L compact, the two first latches 101, 102 of the first latching/snap-action element are arranged so as to be offset relative to the two second latches 10′, 10″ of the second latching/snap-action element counter to the climbing direction.
First distances from the longitudinal axis L of the two first latches 101, 102 differ from distances of the two second latches 10′, 10′ from the longitudinal axis, wherein the first distances are selected to be smaller than the second intervals. The two first latches 101, 102 interact with the first climbing shoe rail and the two second latches 10′, 10″ interact with the second climbing shoe rail. An inverted embodiment in which the two first latches 101, 102 interact with the second climbing shoe rail and the two second latches 10′, 10″ interact with the first climbing shoe rail is also possible. The first climbing shoe rail can be designed as a climbing lift rail and the second climbing shoe rail can be designed as a climbing rail.
The features of the invention described with reference to the illustrated embodiment, such as the latches 10a, 10b arranged next to each other according to
