Furthermore, the invention relates to a climbing unit for arrangement on a building, comprising:
Furthermore, the invention relates to a climbing device comprising:
The invention further relates to a climbing system comprising:
Finally, the invention relates to a method for erecting a building from concreting portions arranged one above the other.
It is known from EP 3 440 283 B1 to use a different type of self-climbing unit in the construction of building cores. The self-climbing unit is provided with a working platform and can be converted from a lower, completed concrete wall section to a further concrete wall section placed above another without the need of a crane. For such a climbing process, lifting cylinders are used, which are supported on climbing brackets, which are each releasably anchored in anchoring points of a lower concrete wall section. The working platform and the concrete formwork elements are attached to work brackets, which are anchored to the concrete component above the climbing brackets. For fastening the work and climbing brackets in the concreting portions, anchor bolts are used, which are introduced into the respective concreting portion. EP 3 440 283 B1 addresses the problem that the concrete wall anchors must be arranged in predetermined positions, but they may collide with the reinforcement steel rods to be embedded there. Therefore, the reinforcing steel rods must be partially guided around the anchoring points. However, this can lead to a structural weakening of the concrete body. The number of anchoring points in the concrete should be kept as low as possible. To achieve this goal, EP 3 440 283 B1 proposes an embodiment with climbing brackets and working brackets. The climbing brackets have first anchor receiving arrangements on a first concreting portion, and the working consoles have second anchor receiving arrangements on a second concreting portion, which correspond in their pattern with respect to their relative positions. In this way, after anchoring the working brackets in anchor holes at third anchoring points of a 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 anchor holes, which have become free in the meantime, of the second anchor points of the second concrete wall section. This allows the number of anchor holes to be halved.
A disadvantage of this state of the art, however, is that the self-climbing unit requires three concreting portions for anchoring to the concrete body for each climbing process (anchoring the climbing brackets in the first concreting portion—climbing the working brackets upwards with the working platform from the second into the third concreting portion—anchoring the working brackets in the third concreting portion—pulling the climbing brackets from the first into the second concreting portion). This requires a very complex and high-level design of the self-climbing unit. Furthermore it is disadvantageous in that the state of the art provides working and climbing brackets with receiving openings for the concrete wall anchors. However, this leads to unfavourable tensile loads at the anchoring points. In addition, the state of the art is only designed for the erection of a building core, wherein the self-climbing unit is supported between opposite wall sections. For this purpose, two support columns are connected to each other at their upper ends via a support frame with cross members. This state of the art would be unsuitable for use on the outside of a building, without support between opposite wall sections.
Furthermore, suspension shoes for climbing formwork are known in the state of the art. From these suspension shoes, a single climbing component, in particular a climbing rail, is suspended. A working platform can be mounted on the climbing rail. For climbing upwards to the next floor, cylinder-piston drives can be used, which are supported on the building or on the suspension shoe fastened to it. The lifting is carried out gradually, i.e. with short forward and backward movements of the cylinder-piston drive. Examples of this are shown in EP 1 899 549 B1 and WO 2008/061922 A1.
Accordingly, the object of the invention is to mitigate or eliminate at least individual drawbacks of the state of the art. This object is achieved with a suspension shoe, a climbing, and a method as described herein.
The invention provides a suspension shoe in which the suspension part has a first mount for releasably holding the first climbing component of the climbing unit, in particular the climbing rail, and a second mount for releasably holding the second climbing component of the climbing unit, in particular the climbing carriage.
With the first and the second mount, the suspension shoe has two fastening points at which, depending on the application and phase of the climbing process, one of the first and the second climbing components can be suspended, or the first and the second climbing components can be suspended at the same time. The first and the second climbing components can be moved relative to one another in the climbing or height direction when repositioning the climbing unit. The first and the second mounts are spaced from each other. If the suspension shoe has a single anchor for anchoring in the concrete, the number of anchoring points in the concrete can be reduced accordingly. A significant advantage over the state of the art is thus that two fastening points are created per anchor. Thus, the suspension shoe only needs a single anchoring point in the concrete. In a preferred embodiment, the first and the second mounts are used for selectively suspending the climbing rail and the climbing carriage. For example, the climbing rail may first be suspended from the first mount of the suspension shoe before the climbing carriage climbs upwards and is suspended from the second mount of the same suspension shoe. With the suspension shoe according to the invention, two independent fastening or suspension points are created by the first and the second mount. The suspension shoe according to the invention (or a plurality of such suspension shoes) may be part of a climbing unit during the cyclical erection of the building from concreting portions. It is advantageous that when moving from one concreting portion to the next, no more than two concreting portions arranged one above the other are required for anchoring in the concrete. In contrast to the state of the art, it is not absolutely necessary to temporarily suspend the climbing unit from a third concreting portion when climbing upwards to the next floor.
For the purposes of this disclosure, the location and direction indications, such as “horizontal,” “vertical,” “one above the other,” “next to one another,” refer to the intended use of the suspension shoe, the climbing unit, and the climbing device in the mounted state on a building having a vertical concreting portion. Depending on the design, concreting portions inclined to the vertical may also be produced with the suspension shoe, the climbing unit and the climbing device, in which case the location and direction indications can then be transmitted accordingly.
In a first climbing position, i.e. when climbing from one concreting portion to the next, the first climbing component, in particular the climbing rail, can be fixed in its respective height position relative to the suspension shoe by the suspension on the first mount of the suspension shoe. Thus, in this embodiment, the first climbing component, in particular the climbing rail, is secured in the first climbing position not only against a downward movement, but also against an upward movement. The load of the climbing unit is transmitted to the suspension shoe via the first climbing component and diverted from the suspension shoe into the concreting portion of the building. In the first climbing position, the second climbing component, in particular the climbing carriage, may be detached from the second mount of the suspension shoe to allow the second climbing component to climb upwards by a displacement relative to the first climbing component.
In a second climbing position, the second climbing component, in particular the climbing carriage, can be fixed by the suspension on the second mount of the suspension shoe in its respective height position relative to the suspension shoe and thus to the building. Thus, in this embodiment, the first second climbing component, in particular the climbing carriage, is secured in the second climbing position not only against a downward movement, but also against an upward movement. The load of the climbing unit is transmitted to the suspension shoe via the second climbing component and diverted from the suspension shoe into the concreting portion of the building. In the second climbing position, the first climbing component, in particular the climbing rail, may be detached from the first mount of the suspension shoe to allow the first climbing component to climb upwards by a displacement relative to the second climbing component.
In addition, in a holding position, the first climbing component may be attached to the first mount and the second climbing component may be attached to the second mount. In an application as climbing formwork, the holding position may be a concreting position when concreting a concreting portion.
In a preferred embodiment, the first mount has a first holding opening for the passage of a first holding bolt and/or the second mount has a second holding opening for the passage of a second holding bolt. As a result, the suspension of the first and the second climbing components can be provided and released quickly and reliably, depending on the phase of the climbing process. In the mounted state on the building, the first and/or the second holding bolt preferably extends substantially perpendicular to the main plane of the suspension part, in particular substantially perpendicular to a base plate of the suspension part. With respect to a neutral position of the suspension part, the first and/or the second holding bolt therefore preferably extends substantially perpendicular to the outer side of the concreting portion facing the suspension part.
As the first and/or second holding bolt, a plug bolt or a threaded screw bolt can be provided in each case.
In order to arrange the fastening points for the suspension of the climbing components in an easily accessible way, the first and the second mounts are preferably provided at substantially the same height on both sides of the anchor.
In order to achieve load or tolerance compensation, it is advantageous if the suspension part is connected to the anchor such that it can be tilted, in particular about a horizontal axis. The maximum tilt angle with respect to a substantially vertical starting position of the suspension part is preferably at least 5° in both tilting directions, i.e. at least +/−5° with respect to the substantially vertical starting position of the suspension part.
In a preferred embodiment, the anchor comprises a ball element and the suspension part comprises a ball socket, wherein the ball element of the anchor is tiltably arranged in the ball socket of the suspension part. This embodiment has the advantage, on the one hand, that an effective force transmission is achieved by reducing the tensile forces. The suspension part can be held directly by the (wall) anchor via the ball joint formed from the ball socket and the ball element. In the mounted state on the building, the suspension part is spaced from the outside of the concreting portion facing the suspension part in order to release the tiltability of the suspension part with respect to the anchor. Since the suspension part, unlike in the state of the art, is not supported on the concrete, the tensile forces of the anchor can be significantly reduced. As a result, the weight of the suspension shoe can be significantly reduced. This embodiment is also particularly advantageous when two such suspension shoes are used in pairs, which in particular can be arranged next to one another at essentially the same height in order to guide the first climbing component, in particular the climbing rail, between the two suspension shoes. Since the ball socket is freely rotatable, tolerance compensation of the anchors of the two suspension shoes in the concrete can be obtained. The two ball sockets can be precisely aligned with each other, so that the climbing components have a common axis of rotation, whereby the two concrete anchors receive essentially the same load. Thus, a type of balance beam can be realised.
For the secure suspension of the climbing components, it is advantageous if the suspension part has a receiving groove, in particular extending in the horizontal direction, for receiving a first coupling strip on the first climbing component and/or a second coupling strip on the second climbing component.
With regard to a stable yet lightweight design, the suspension part preferably has a base plate, in which the receiving groove and/or the ball socket are preferably integrated. For example, the base plate may be designed as a milled part. Preferably, the base plate has one respective recess for the receiving groove and/or the ball socket. Preferably, the suspension part with the base plate in the mounted state on the building is spaced apart from the outside of the concreting portion facing the suspension part, in order to reduce the tensile forces of the anchor and thus enable a particularly weight-saving design. With respect to the neutral position, the main plane of the base plate in the mounted state on the building preferably extends substantially parallel to the planar outer side of the concreting portion.
The climbing unit according to the invention for arrangement on a building, has at least:
Thus, a climbing bracket and a working bracket as in the state of the art can be dispensed with. Instead, a suspension shoe with a suspension part is provided, on which, in one phase of the climbing process when moving to the next floor, the climbing carriage, but not the climbing rail, can be suspended, and in a second phase, the climbing rail, but not the climbing carriage, can be suspended from the suspension shoe.
In an embodiment variant, in particular for climbing on an outside of the building, i.e. during façade climbing, the holding device is arranged at the upper end of the climbing rail. In another embodiment variant, in particular for climbing between opposite wall sections of a shaft, the holding device can be arranged on a central longitudinal section, between the opposite ends.
In a holding position, in particular a concreting position, the holding device on the climbing carriage can be connected to the second mount of the first suspension shoe and the fastening device on the climbing rail can be connected to the first mount of the first suspension shoe.
For a quick and stable connection, the fastening device connected to the climbing rail preferably has a fastening opening for arranging the first holding bolt and/or the holding device connected to the climbing carriage has a suspension opening for arranging the second holding bolt. The suspension opening of the holding device and the second holding opening of the suspension shoe can be arranged in alignment, wherein the second holding bolt passes through the suspension opening and the second holding opening for connection. Accordingly, the fastening opening of the fastening device and the first holding opening of the suspension shoe can be arranged in alignment, wherein the first holding bolt passes through the fastening opening and the first holding opening for connection.
For stable and secure suspension, the fastening device on the climbing rail has a first coupling strip and/or the holding device on the climbing carriage has a second coupling strip, in each case for preferably substantially precisely fitting arrangement in the receiving groove of the first suspension shoe. If the suspension part is tiltably arranged on the anchor, undesired rotation of the suspension part about the longitudinal axis of the anchor can also be prevented by the engagement of the first or second coupling strip in the receiving groove of the first suspension shoe.
In a preferred embodiment, a second suspension shoe, which is designed according to one of the embodiments of the suspension shoe described above, is provided for anchoring to the same concreting portion.
In the first climbing position, the holding device on the climbing carriage is connected in each case to the second mount of the first and the second suspension shoes, the fastening device on the climbing rail being released in each case from the second mount of the first and the second suspension shoes. This allows the climbing rail to be moved along the first and the second suspension shoes.
In the second climbing position, the fastening device on the climbing rail is connected to the first mount of the first and the second suspension shoes, respectively, the holding device on the climbing carriage being detached from the second mount of the first and the second suspension shoes, respectively. This allows the climbing carriage to be moved along the climbing rail.
In order to fix the climbing rail and the climbing carriage in their respective height positions depending on the phase of the climbing process or to release the climbing upwards, the first and the second suspension shoes are preferably arranged substantially at the same height on both sides of the climbing rail. In this embodiment, the first and the second suspension shoes are located adjacent to the opposite longitudinal sides of the climbing rail. In the second climbing position, the climbing rail can be guided upwards between the first and the second suspension shoes relative to the climbing carriage.
Preferably, the first mounts of the first and the second suspension shoes are located on the side of the climbing rail, relative to the vertical plane through the longitudinal axis of the anchor, and the second mounts of the first and the second suspension shoes are located, again relative to the vertical plane through the longitudinal axis of the anchor, on the side facing away from the climbing rail. This makes it possible to create structurally simple suspensions for the climbing rail and the climbing carriage.
In a preferred embodiment, the climbing carriage has a holding fork with two fork elements on both sides of the climbing rail, wherein the two fork elements, in particular at their free ends, each carry a holding element, in particular a holding plate, of the holding device, which in the first climbing position, in particular via the second holding bolt, are connected to the second mounts of the first and the second suspension shoes. Due to the holding fork, the two holding elements of the holding device can be reversibly detachably connected to the second mounts of the first and the second suspension shoes on both sides of the climbing rail. Preferably, a vertical centre plane of the holding fork between the two fork elements contains the longitudinal axis of the anchor of the suspension shoe.
In order to achieve reliable guidance during climbing upwards, in a preferred embodiment, the climbing carriage has a guide shoe for guiding along the climbing rail, in particular for gripping around a climbing profile of the climbing rail.
Preferably, a horizontal central axis of the guide shoe extends substantially along a vertical central plane of the climbing rail perpendicular to the adjacent concreting portion of the building. When the climbing carriage has the holding fork, the horizontal central axis of the guide shoe extends substantially centrally between the two fork elements. As a result, a particularly favourable load transfer between anchoring points arranged one above the other can be achieved.
In order to suspend the climbing rail in the second climbing position, in a preferred embodiment, the fastening device has a fastening plate with a bearing section and two fastening sections on both sides of the bearing section, wherein the bearing section is connected to the climbing rail, preferably via a bearing journal, and the fastening sections are connected to the first mounts of the first and the second suspension shoes, preferably via the two first holding bolts, in the second climbing position.
Preferably, the climbing carriage has a pivot axis about which the holding fork can be pivoted. This pivot axis is preferably arranged substantially in line with the longitudinal axis of the bearing journal, which allows the fastening plate to pivot. The holding fork can thus be pivoted together with the fastening plate on the climbing rail, for example, in order to compensate for anchoring points in the concrete of the first and the second suspension shoes that are not exactly arranged in the horizontal. As a result, a uniform load transfer in the anchoring points in the concrete is achieved.
Preferably, the longitudinal axis of the bearing journal extends along the vertical centre plane of the guide shoe.
In a preferred embodiment, a support part for support on the outside of the building, in particular on the lower end of the climbing rail, is connected to the climbing rail.
In a preferred embodiment, in particular for an embodiment when climbing on the outside of the building, a climbing scaffold is provided with the climbing carriage.
In this embodiment, the climbing scaffold may have a preferably vertical column element, which preferably extends substantially parallel and preferably at a horizontal distance perpendicular to the vertical outer side of the building to the climbing rail. This embodiment is particularly suitable for climbing on the outside of the building.
In addition, the climbing scaffold preferably has a supporting element for support on the outside of the building. The support element is preferably arranged on a horizontal beam. The horizontal beam is preferably attached to the lower end of the column element.
In a preferred embodiment, the climbing scaffold has a guide element for guiding along the climbing rail, the guide element preferably being arranged below the guide shoe. The guide element can engage around a flange of a climbing profile of the climbing rail. Furthermore, it is advantageous if the guide element is connected to the column element of the climbing scaffold via a support element.
For climbing upwards into the next concreting portion, it is advantageous if the climbing unit has a self-climbing drive, in particular with a cylinder-piston drive, for displacing the climbing carriage relative to the climbing rail and vice versa. The self-climbing drive is configured for power transmission between the climbing rail and the climbing carriage, so that an actuation of the self-climbing drive in the first climbing position moves the climbing rail upwards, in particular by a single stroke of the cylinder-piston drive, i.e. by a single retraction or extension of the piston, and a further actuation of the self-climbing drive in the second climbing position moves the climbing carriage upwards, by a single stroke of the cylinder-piston drive.
Preferably, the longitudinal axis of the cylinder-piston drive is arranged substantially vertically to allow a maximum stroke.
In a preferred embodiment, in particular for climbing on the outside of the building, a boom is provided, which extends from the climbing rail, in particular from the lower end of the climbing rail, to the rear, i.e. away from the adjacent concreting portion of the building.
In a preferred embodiment, the self-climbing drive, in particular the first longitudinal end of the cylinder-piston drive, is connected to the boom.
In a preferred embodiment, in particular for climbing on the outside of the building. the climbing scaffold has the column element to which the self-climbing drive is connected. With this embodiment, the power of the self-climbing drive can be effectively transferred to the climbing scaffold to allow the climbing scaffold to climb upwards.
In an alternative embodiment, a crane for raising the climbing unit is provided instead of the self-climbing drive.
In a preferred embodiment, the climbing scaffold has a further column element, wherein a strut truss is preferably provided between the column element and the further column element. In use, the further column element preferably extends at a horizontal distance perpendicular to the vertical outer side of the building behind the column element.
For purposes of this disclosure, “forward” means closer to the building and “rearward” means facing away from the building.
It is particularly preferred if the climbing rail, the column element, and the further column element are arranged along a vertical plane perpendicular to the outside of the building. In this embodiment, the climbing unit is designed as a substantially two-dimensional climbing pulley. This embodiment is particularly suitable for use as part of a climbing device described in more detail below, having a plurality of climbing units arranged at a horizontal distance in the direction parallel to the outside of the building.
The climbing unit preferably has at least one further climbing shoe, in particular a pair of further climbing shoes arranged next to one another, above the first suspension shoe (and optionally the second suspension shoe), in particular on an overlying concreting portion.
The climbing device according to the invention has at least:
two climbing units, which are formed according to one of the embodiments of the climbing unit described above, the two climbing units being arranged next to one another at a horizontal distance on the same concreting portion.
The climbing device preferably has at least one working platform. The working platform preferably has individual platform supports, which can extend in the horizontal direction parallel to the outside of the building. A working platform flooring can be arranged on the platform supports.
In one embodiment, in particular for climbing on the outside of the building, the working platform is connected to the climbing scaffolds having the climbing carriages. In this embodiment, the working platform is moved together with the climbing scaffolds at the level of the next concreting portion.
In another embodiment, in particular for climbing within a shaft, the working platform is connected to the climbing rails of the climbing units, so that the working platform is moved together with the climbing rails at the level of the next concreting portion. In a preferred application of the climbing device, a formwork, in particular a wall formwork, is provided. The formwork has at least one formwork element, in particular a wall formwork element, which is movable between a forming position and a stripping position, in particular at least in the horizontal direction perpendicular to the outside of the building.
In one embodiment, in particular for climbing on the outside of the building, the formwork is supported on a scaffolding part of the climbing scaffold from below and/or is suspended from a cantilever part of the climbing scaffold from above.
In another embodiment, in particular for climbing within a shaft, a bridging frame is connected to the climbing rail, wherein the formwork is suspended from the bridging frame.
The climbing system according to the invention comprises at least:
Preferably, the climbing system comprises a climbing device having a plurality of climbing units of one of the embodiments described above, the anchors of the first suspension shoes of the climbing units each being anchored within the same concreting portion of the building.
Preferably, the climbing system comprises at least one further suspension shoe, in one of the embodiments described above, which is anchored to a second concreting portion above the first concreting portion. Upon completion of the climbing process, the first suspension shoes (or parts of the first suspension shoes) can be recovered and used when erecting a concreting portion higher up.
In the method according to the invention for erecting a building from concreting portions arranged one above the other, at least the following steps are carried out, preferably in the order indicated:
The method preferably also comprises the step of:
If the method is used for climbing formwork, the method can be extended by additional steps. In this embodiment, the following steps can also be carried out, in particular in a holding position of the climbing unit:
The stripping position is configured to release the movement of the climbing rail into a fourth concreting portion (i.e. into a position overlapping with the third concreting portion).
Depending on the number of floors, the preceding steps can be repeated as often as desired.
In a preferred embodiment, the movement of the climbing rail along the first suspension shoe, i.e. step v. above, and/or the movement of the climbing carriage along the climbing rail, i.e. step vii. above, in particular by the height of the first or second concreting portion, is effected in each case by a single stroke (i.e. by a single extension or a single retraction) of a cylinder-piston drive of a self-climbing drive.
In a first embodiment, when climbing along an outside of the building, the method is performed with a climbing device having a plurality of climbing units, wherein the climbing scaffolds and the climbing rails of the climbing units are each moved substantially parallel and at the same height.
In a second embodiment, the method is performed while climbing between opposing wall portions of a shaft of the building.
The present disclosure also relates to a self-climbing device, particularly a self-climbing formwork, as follows.
A self-climbing device, in particular a self-climbing formwork, comprising:
In this embodiment, the suspension shoe can be designed according to one of the embodiments described above. However, another embodiment of the suspension shoe, in particular with only one fastening point for the climbing rail or the climbing scaffold, may also be provided. The climbing rail, the climbing scaffold, the self-climbing drive, and optionally other components of the self-climbing device may be configured as in the embodiments of the climbing device described above.
On the one hand, façade climbing formworks with climbing rails, which are guided on climbing shoes on the façade, are known in the state of the art. However, the climbing drive is supported on the building or suspension shoe and must be activated in short strokes. On the other hand, the state of the art according to EP 3 440 283 B1 is not designed for climbing on the outside of the building. The self-climbing device in the above embodiment combines the advantages of known façade climbing systems with an efficient self-climbing drive, with which the climbing scaffold and the climbing rail can be quickly and easily moved into the next concreting portion, in particular by a single stroke of a cylinder-piston drive.
The invention will be further discussed below with reference to a preferred exemplary embodiment.
