Description

[0001] The invention relates to a climbing rail for guiding a climbing shoe along a structure, comprising: a first rail part and a second rail part.

[0002] Furthermore, the invention relates to a climbing frame comprising: a climbing rail for guiding a climbing shoe along a structure, a working platform on a first level, and a trailing platform on a second level below the first level.

[0003] Furthermore, the invention relates to a climbing frame comprising: a climbing rail for guiding a climbing shoe along a structure, and a protective shield with a first shield element and a second shield element.

[0004] Furthermore, the invention relates to a structure with at least one concreting section, with a climbing rail and with a climbing shoe, wherein the climbing rail is held on the concreting section via the climbing shoe.

[0005] Finally, the invention relates to a method for constructing a building.

[0006] The state of the art is defined by FR 2 370 150 A1, US 4 892 169 A and WO 2017 / 072654 A1.

[0007] From EP 2 279 310 B1, a self-climbing formwork system is further disclosed, in which climbing rails are guided in climbing shoes. The climbing rails are integrated into a scaffold unit that includes a working platform for erecting external formwork. A trailing platform is also provided, which, like the working platform, is attached to the climbing rail. Extension pieces for the climbing rails can be detachably or pivotably attached to their lower free ends. However, a disadvantage is the considerable effort required to provide and install the extension pieces. Furthermore, the climbing rails can only be extended by the predetermined lengths of the extension pieces.

[0008] In contrast, the object of the present invention is to alleviate or eliminate at least some disadvantages of the prior art. The invention preferably aims to create a climbing rail and a climbing frame equipped with it, which can be easily, compactly, and stably adapted to different construction situations.

[0009] This task is solved with a climbing rail according to claim 1, a climbing frame according to claim 5 or claim 10, a structure according to claim 11 and a method according to claim 12.

[0010] Preferred embodiments are specified in the dependent claims.

[0011] According to the invention, the second rail part is telescopically connected to the first rail part between a collapsed and an extended state.

[0012] To extend the climbing rail, for example after starting the concreting of higher concrete sections, the climbing rail comprises a first rail section and a second rail section. The second rail section is telescopically connected to the first rail section, allowing the first and second rail sections to be moved between their retracted and extended positions. In a preferred embodiment, the second rail section can be extended relative to the first rail section to increase the length of the climbing rail, i.e., the longitudinal extension from the upper end of the first rail section to the lower end of the second rail section, to accommodate different floor heights of the structure. Advantageously, the climbing rail according to the invention can be adjusted in multiple stages, preferably essentially steplessly, in length.Furthermore, it is advantageous that the second rail section can be permanently connected to the first rail section and can be collapsed or extended depending on the phase of the climbing process. This simplifies logistics on the construction site. The design according to the invention can also be advantageous at the beginning of the construction of the structure if the climbing rail, in the collapsed state of the first and second rail sections, can be arranged in a space-saving manner. In the extended state, depending on the position of the climbing rail relative to the climbing shoe, a guide surface of the first rail section or a guide surface of the second rail section can be guided in the climbing shoe. In a preferred embodiment, the second rail section, in the extended (i.e., telescoped) state, is designed to extend the first rail section downwards.

[0013] For the purposes of this disclosure, location and direction specifications such as "top," "bottom," "vertical," and "horizontal" refer to the intended state of use of the climbing rail in a vertical orientation on a structure. In a preferred application, a climbing frame with the climbing rail is a component of a climbing formwork for concreting the concrete sections. Vertical concrete sections can be cast using the climbing formwork. Of course, inclined concrete sections can also be produced using the climbing formwork, whereby the location and direction specifications are to be transferred accordingly.

[0014] In one preferred application, a climbing formwork is connected to the climbing rail. In another application, a protective shield is connected to the climbing rail.

[0015] In a preferred embodiment, the second rail section has a stop to limit the telescoping of the second rail section from the retracted state to the extended state.

[0016] In order to ensure reliable guidance of the climbing rail along the climbing shoe, a guide device is provided according to the invention for displacing the second rail part in a direction perpendicular to the longitudinal direction of the first rail part, i.e., in the case of vertical orientation of the climbing rail, in a horizontal direction, in particular forwards, i.e., towards the attachment side of the climbing shoe on the structure.

[0017] According to the invention, the guide device is designed to move a guide surface on the front of the second rail section forward, towards the attachment side of the climbing shoe to the structure, such that, in the extended state, the guide surface on the front of the second rail section is arranged essentially in the same (vertical) plane as the guide surface on the front of the first rail section. Thus, in the extended state, the guide surface on the front of the second rail section extends the guide surface on the front of the first rail section. During climbing, this allows for a continuous transition from the guidance of the first rail section on the climbing shoe to the guidance of the second rail section on the climbing shoe.

[0018] To achieve the displacement of the second rail section substantially perpendicular to the extension direction of the second rail section, the guide device can have at least one sliding bearing and / or at least one roller bearing. The sliding bearing has at least one sliding surface on one side of the first and second rail sections and a sliding element on the other side of the first and second rail sections, wherein the sliding element slides on the sliding surface as the second rail section is telescoping. The roller bearing has at least one rolling surface on one side of the first and second rail sections and a rolling element on the other side of the first and second rail sections, wherein the rolling element rolls on the rolling surface.

[0019] In a preferred embodiment, the sliding or rolling bearing has at least one first sliding or rolling surface inclined to the longitudinal direction of the first rail part, i.e., running at an angle of inclination deviating from 0° or 180°, for converting the vertical movement of the telescoping of the second rail part into a horizontal movement for moving the second rail part forwards.

[0020] In a preferred embodiment, the sliding element, which is provided in particular on the second rail part, slides on the first sliding surface, which is provided in particular on the first rail part, when the second rail part is telescoping, such that the second rail part is moved forward when the extended state is reached.

[0021] In a first embodiment, a wedge element is provided as the sliding element, which has a second sliding surface that is preferably inclined to the longitudinal direction of the first rail section (at an angle of inclination other than 0° or 180°) in accordance with the first sliding surface. Thus, in this embodiment, a wedge guide is provided for converting the telescoping movement, i.e., the extension movement of the second rail section relative to the first rail section, into the horizontal movement for displacing the second rail section essentially perpendicular to it.

[0022] In a second design variant, a round element, for example a round steel bar, is used as the sliding element, which slides on the first sliding surface. This design is characterized by good sliding properties.

[0023] In a preferred embodiment, the sliding bearing has two first sliding surfaces spaced apart from each other in the longitudinal direction of the first rail section. In this embodiment, the sliding bearing also has two sliding elements on the second rail section, spaced apart from each other in the longitudinal direction of the second rail section, wherein the two sliding elements can slide on the two first sliding surfaces on the first rail section. In a first variant, two wedge elements are provided as the two sliding elements. In a second variant, one wedge element and one round element are provided as the two sliding elements.

[0024] In a preferred embodiment, a holding device is provided which, in the extended state of the second rail section, is configured to block the second rail section against movement in a direction perpendicular to the longitudinal direction of the first rail section, preferably forwards and backwards. The holding device can have at least one holding surface on the first rail section and one holding surface on the second rail section, which, in the extended state, are arranged side by side, and in particular abut each other, such that the second rail section, in the extended state, is essentially immobilized in a direction perpendicular to the longitudinal direction of the first rail section, particularly forwards and backwards. Advantageously, this secures the second rail section laterally and creates a rigid rail joint. Preferably, the holding surfaces are essentially parallel to the longitudinal direction of the first rail section, i.e.,When the climbing rail is oriented vertically, it is arranged essentially vertically. For a rigid arrangement in the extended state of the second rail section, it is advantageous to provide two retaining surfaces spaced apart longitudinally on the first rail section and two retaining surfaces spaced apart longitudinally on the second rail section.

[0025] In a preferred embodiment, a locking device is provided to block the telescoping of the second rail section relative to the first rail section, particularly in the retracted and / or extended state. The locking device may, in particular, comprise a locking bolt and a bolt opening.

[0026] In a preferred embodiment, the climbing rail has a third rail section for guiding the climbing shoe along the structure, wherein the third rail section is telescopically connected to the first rail section. Preferably, the third rail section is mounted so as to be slidably upwards on the first rail section. In this embodiment, the third rail section is designed as a further telescopic element. The first rail section and the third rail section can be moved between a retracted and an extended state. Thus, the third rail section can be extended upwards relative to the first rail section. The third rail section can be shorter than the first rail section.

[0027] This design is particularly advantageous when a single climbing shoe is used, on which the climbing rail is guided in a climbing position, as the additional rail section reduces the unguided section within the climbing shoe during climbing. Furthermore, the third rail section can be used to connect to a self-climbing drive, for example, an electric and / or hydraulic drive, especially a linear actuator or hydraulic cylinder.

[0028] Preferably, the climbing rail comprises a first rail section, a second rail section, and a third rail section. In the extended position, the second rail section extends the first rail section downwards. The third rail section extends the first rail section upwards in the extended position. Preferably, the third rail section can be telescoped independently of the second rail section relative to the first rail section. Similarly, the second rail section can preferably be telescoped independently of the third rail section relative to the first rail section.

[0029] The third rail section preferably has a further stop to limit the telescoping of the third rail section from a retracted state to an extended state.

[0030] In a preferred embodiment, a further guide device, in particular with at least one further sliding or roller bearing, is provided for displacing the third rail section in a direction perpendicular to the longitudinal direction of the first rail section, i.e., in a horizontal direction when the climbing rail is vertically oriented, particularly forwards, i.e., towards the attachment side of the climbing shoe on the structure. With the aid of the further guide device, a guide surface on the front of the third rail section can be displaced forwards, towards the structure, such that, in the extended state, the guide surface on the front of the third rail section is arranged essentially in the same (vertical) plane as the guide surface on the front of the first rail section.

[0031] The additional guide device can be designed according to one of the above-described embodiments of the guide device. Thus, the additional guide device can have at least one further roller or sliding bearing, preferably an upper and a lower sliding bearing.

[0032] Depending on the design, the first and / or the second and / or the third rail section has longitudinally spaced retaining elements, each designed to connect to a bracket of the climbing shoe in order to hold the climbing frame in a concreting position at a predetermined height. In a preferred embodiment, the retaining elements of the climbing rail are designed as claws. Furthermore, it is preferred if the bracket of the climbing shoe has at least one retaining bolt.

[0033] In a preferred embodiment, the climbing rail comprises a first rail section, a second rail section, and a third rail section. Depending on the embodiment, further rail sections may also be provided. For example, a fourth rail section may be telescopically connected to the second rail section.

[0034] The first and / or the second and / or the third rail section preferably has a profile section, in particular a double U-profile, which preferably extends substantially over the entire length of the first, second, or third rail section, respectively. The guide surface for guiding the climbing shoe can be provided on a front flange of the respective profile section, in particular the double U-profile, which faces the structure.

[0035] In a double-U profile configuration, two U-profiles are connected to each other, each having a front flange, a rear flange, and a web connecting the front and rear flanges. The two front flanges of the U-profiles are preferably arranged substantially parallel to the vertical outer surface of the structure on which the climbing shoe is mounted.

[0036] In a preferred embodiment, the U-profiles of the double U-profile of the second rail section are guided in receptacles of the U-profiles of the double U-profile of the first rail section. Preferably, the U-profiles of the double U-profile of the second rail section are connected to each other at their upper end by a stop element. Furthermore, an additional connection between the U-profiles of the double U-profile of the second rail section can be provided at the lower end of the second rail section. The U-profiles of the double U-profile of the first rail section can be connected to each other via connections between the webs.

[0037] In an alternative embodiment, the first and / or the second rail section can have an I-profile. The profiles of the first or second rail section are guided in recesses of the first or second rail section, respectively.

[0038] A climbing frame according to the invention has: a climbing rail for guiding a climbing shoe along a structure, a working platform on a first level, a trailing platform on a second level below the first level, wherein the climbing rail is designed according to one of the embodiments described above.

[0039] In a preferred embodiment, the first rail section is provided on a work platform unit comprising the work platform and the second rail section is provided on a trailing platform unit comprising the trailing platform.

[0040] The work platform preferably comprises a platform element with a preferably horizontal support or working surface, which defines the first level of the climbing frame. In a preferred application, wall formwork is provided on the work platform in a sliding and / or tilting manner. Furthermore, the trailing platform preferably comprises another platform element with a further, preferably also horizontal, support or working surface, which defines the second level of the climbing frame. The trailing platform is preferably used for transferring climbing shoes.

[0041] In a preferred embodiment, the trailing platform has a support, in particular a horizontal support, which is preferably attached to the climbing rail. A platform element with a further, preferably horizontal, work surface for workers can be arranged on the support. The trailing platform serves to remove and transfer climbing shoes in preparation for climbing to the next concreting section.

[0042] To adjust the depth of the working platform and / or the trailing platform (i.e., its horizontal extension perpendicular to the climbing rail away from the structure) depending on the application, it is advantageous if the support beam of the trailing platform and / or a support of the working platform is telescopic. Extending or retracting the telescopic beam or support lengthens or shortens the beam accordingly.

[0043] In a preferred embodiment, a support device with a support element, in particular with a support roller, is provided for support on the outside of the structure, wherein the support device has a telescopic element for adjusting the height of the support element, wherein the second rail part of the climbing rail is provided as the telescopic element.

[0044] To provide load support, especially when climbing the climbing frame, the support device with its support element is designed for external mounting on the structure. Because it is mounted externally, the support element does not penetrate the concrete structure and is not anchored to it. This reduces assembly effort. The support element can, in particular, replace an additional climbing shoe.

[0045] A support roller for rolling along the outside of the structure is preferably provided as a support element of the support device. The support roller forms a pressure point on the structure, which transfers the load of the climbing frame.

[0046] To adapt the climbing frame to different floor heights of the concrete pouring sections, the support device preferably includes a telescopic element for adjusting the height of the support element. If the second rail section of the climbing rail is provided as the telescopic element, both the length of the climbing rail and the height of the support element can be adjusted. In this embodiment, the support element, in particular the support roller, is provided on the second rail section, especially at its lower end. For climbing, the climbing rail can be extended into the extended position of the first and second rail sections, with the support element, in particular the support roller, being supported against the structure.

[0047] This version can be independent of the previously described version of the telescopic climbing rail.

[0048] Thus, the present disclosure further relates to a climbing frame, in particular for a climbing formwork, comprising: a climbing shoe, a climbing rail for guiding the climbing shoe along a structure, a work platform on a first level, a trailing platform on a second level below the first level, a support device with a support element for bracing on the outside of the structure.

[0049] To adapt the climbing frame to different floor heights of the concrete pouring sections, it is advantageous if the support device has a telescopic element for adjusting the height of the support element, wherein the telescopic element is preferably slidable on the climbing rail, in particular on the second rail section of the climbing rail. In one embodiment, the telescopic element is formed by the second rail section. In another embodiment, the telescopic element is formed by a cantilever that is not guided in the climbing shoe.

[0050] The climbing shoe is provided for during the construction of the structure, with the climbing rail guided in the climbing shoe.

[0051] In a preferred embodiment, the climbing shoe is the only climbing shoe on which the climbing rail is guided in a climbing position. The climbing position refers to the climbing frame's ascent from one concreting section to the next. This design offers numerous advantages. For example, a second trailing platform is unnecessary. Preferably, the climbing frame therefore has only a single trailing platform. Furthermore, stresses during climbing can be reduced. The material is protected, and peak loads are avoided. Additionally, a simple drive system can be used for climbing. Finally, attaching the climbing frame to the structure is simplified by connecting the climbing frame to the climbing shoe.

[0052] A version with a single climbing shoe per climbing rail in a climbing position can be provided regardless of the specific design of the climbing rail.

[0053] Thus, the present disclosure further relates to a climbing frame, in particular for a climbing formwork, comprising: a climbing shoe, a climbing rail for guiding along the climbing shoe on a structure, a working platform on a first level, a trailing platform on a second level below the first level, wherein the climbing rail is guided in a climbing position in a single climbing shoe, preferably also a support device with a support element for support on the outside of the structure.

[0054] As is common with climbing frames, a further climbing rail can be provided, which is arranged at a lateral distance from the main climbing rail. In this design, the climbing frame has at least two climbing rails, particularly at the same height, each of which is held to the structure by at least one, preferably a single, climbing shoe. The climbing shoe, on which the climbing rail is guided, is provided for connecting the frame to the structure. In a design with a second climbing rail, at least a second climbing shoe is provided, on which the second climbing rail is guided.

[0055] For independent climbing to the next concreting section, a self-climbing drive, such as a linear drive, is preferred. Alternatively, the climbing frame can be lifted using a crane.

[0056] A climbing frame according to the invention has: A climbing rail for guiding a climbing shoe along a structure, a protective shield with a first shield element and a second shield element, wherein the climbing rail is designed according to one of the embodiments described above, the first shield element being attached to the first rail section and the second shield element to the second rail section. The protective shield provides temporary fall protection at the edge of floor slabs.

[0057] In a structure according to the invention, at least one concreting section, a climbing rail in one of the embodiments described above and a climbing shoe are provided, wherein the climbing rail is held on the concreting section via the climbing shoe.

[0058] In a method according to the invention for erecting a building, at least the following steps are carried out: Attaching a climbing shoe to a first concreting section, connecting a climbing rail according to one of the embodiments described above to the climbing shoe on the first concreting section, concreting a second concreting section, climbing the climbing rail, concreting a third concreting section.

[0059] In a preferred embodiment, the second rail part is moved from the retracted state to the extended state, particularly before or during climbing the climbing rail.

[0060] In a preferred embodiment, the climbing rail is guided section by section in a single climbing shoe during climbing.

[0061] The invention is further explained below with reference to preferred embodiments.

[0062] Fig. 1 Figure 1 shows a climbing frame 1, here as part of a climbing formwork system, which has an elongated climbing rail 2 and a climbing shoe 3 in which the climbing rail 2 is received. The climbing frame 1 can alternatively be used with a protective shield for edge protection (not shown). Also not shown is another climbing rail, which is arranged at a lateral distance and parallel to the climbing rail on another climbing shoe. The climbing frame 1 is used in the construction of a structure 4, which has several superimposed concrete pouring sections 5 (see Figure 3). Fig. 2 ) exhibits. A horizontal support 6 of a work platform 7 is attached to the climbing rail 2. The support 6 carries a platform element with a horizontal work surface (cf. Fig. 2 ). The work area is enclosed on the side facing away from structure 4 with barrier elements 7a (see below). Fig. 2 ) secured to a post 7b, which is connected to the end of the support 6 facing away from the structure 4. A wall formwork 8 is slidably mounted on the support 6 between a closed and an open position. The working platform 7 serves to open and close the wall formwork 8. The climbing frame 1 also has a support 9 for a trailing platform 10 (see figure). Fig. 3 ) on. The support 9 carries another stage element with another horizontal work surface. The additional work surface of the trailing stage 10 is located on a second horizontal plane below the first horizontal plane of the work surface of the work platform 7. Like the work surface of the work platform 7, the additional work surface of the trailing stage 10 is also secured by further locking elements 10a (see Fig. 3 ) secured to a further support 10b, which is attached to the end of the beam 9 facing away from the structure 4. Furthermore, a concreting platform 11 can be provided on a third horizontal level above the first horizontal level. From the concreting platform 11, the closed formwork is filled with concrete and then compacted.

[0063] In the embodiment shown, the climbing frame 1 has a support truss 12 below a first diagonal brace 13, which supports the work platform 7 on the climbing rail 2. The support truss 12 has a first brace triangle 14, which is formed by a section of the first diagonal brace 13, a second diagonal brace 15, and an upper section of a longitudinal brace 16. The first brace triangle 14 has a first node 14a between the longitudinal brace 16 and the first diagonal brace 13. In the embodiment shown, the first node 14a is located essentially midway between the ends of the first diagonal brace 13. A second node 14b is formed between the second diagonal brace 15, the first diagonal brace 13, and the climbing rail 2. A third node 14c is formed between the second diagonal strut 15 and the longitudinal strut 16.Furthermore, a connecting strut 17 extends between the first node 14a of the first strut triangle 14 and the climbing rail 2 above the second node 14b.

[0064] In the embodiment shown, the supporting truss 12 also has a second brace triangle 18, which connects to the underside of the first brace triangle 14. The second brace triangle 18 is formed by the second diagonal brace 15, a third diagonal brace 19, and a section of the climbing rail 2. The third diagonal brace 19 is attached to the third node 14c of the first brace triangle 14. The section of the climbing rail 2 extends below the upper section of the climbing rail 2, which is formed between the point of application of the first diagonal brace 13 and the connecting brace 17 on the climbing rail 2.

[0065] In the embodiment shown, the supporting truss 12 also has a third brace triangle 20, which connects to the underside of the second brace triangle 18. The third brace triangle 20 is formed by the third diagonal brace 19, a further section of the longitudinal brace 16 directly below the first section of the longitudinal brace 16, and a fourth diagonal brace 21.

[0066] As from Fig. 1 As can be seen, the third diagonal brace 19 and the longitudinal brace 16 are each formed by two parallel and adjacent longitudinal profiles, here U-profiles or hollow profile elements, which are arranged at a distance from each other via connections 22. This leaves openings between the connections through which the support 9 for the trailing platform 10 passes.

[0067] In the embodiment shown, the climbing frame 1 further comprises a trailing platform unit 23 comprising the trailing platform and a work platform unit 25 comprising the work platform, wherein the trailing platform unit 23 is pivotably connected to the work platform unit 25 via a joint 24. Fig. 1 The climbing frame 1 is shown in the fixed position of the trailing platform unit 23, in which a releasable locking device 26 blocks the pivoting of the trailing platform unit 23 relative to the work platform unit 25. The trailing platform unit 23 has the longitudinal strut 16, which is connected via the joint 24 to the first diagonal strut 13 on the work platform unit 25. The joint 24 defines a horizontal pivot axis perpendicular to the support 6. In the embodiment shown, the climbing rail 2 consists of a first rail section 2a and a second rail section 2b, wherein the first rail section 2a is located on the work platform unit 25 and the second rail section 2b of the climbing rail 2 is located on the trailing platform unit 23.

[0068] In the embodiment shown, the climbing frame 1 further features a support device with a support element 27 for support on the outside 4a of the structure 4 (see figure). Fig. 5 A support roller is provided as a support element 27, which is attached to the lower end of a telescopic element 28. The telescopic element can be extended to varying degrees from the lower part of the climbing rail 2b to adjust the height of the support element 27. The support device also includes a telescopic support strut 29, one end of which is pivotally attached to the lower end of the telescopic element 28. Furthermore, the support strut 29 is connected to a node between the fourth diagonal strut 21 and the longitudinal strut 16.

[0069] The construction of structure 4 using climbing frame 1 is illustrated by the further drawings.

[0070] In the Fig. 2 bis 6 The starting phase is shown.

[0071] In a first step (see Fig. 2 The climbing shoe 3 is anchored to a first concreting section 5a, which can be, for example, a ground floor or basement wall of the structure 4, and which may be constructed at ground level without the climbing formwork 1. The first concreting section 5a therefore does not necessarily have to have been constructed using the climbing formwork 1. The working platform unit 25 is then connected to the climbing shoe 3, with the first rail section 2a of the climbing rail 2 being hooked into the climbing shoe 3. A pressure shoe 30 is attached to the lower end of the first rail section 2a, which supports the lower end of the first rail section 2a on the outside of the structure 4. The trailing platform unit 23 is not connected to the working platform unit 25. On the working platform 7, the wall formwork 8 is closed to construct a second concreting section 5b directly above the first concreting section 5a.

[0072] In a second step (see Fig. 3 The trailing platform unit 23 is reversibly and detachably connected to the working platform unit 25. For this purpose, the upper end of the longitudinal strut 16 is connected to the joint 24 on the first diagonal strut 13. In the embodiment shown, the longitudinal profiles of the longitudinal strut 16 have openings which are aligned with a corresponding opening in the first diagonal strut 13. To form the joint 24, a joint bolt is inserted through the openings in the longitudinal strut 16 and the first diagonal strut 13 and secured. The trailing platform unit 23 is arranged in a pivoted position. The support roller 27 at the lower end of the telescopic element 28 is supported on a base 31 under the first concreting section 5a. The wall formwork 8 is moved away from the second concreting section 5b into the open position. Two further climbing shoes 3 are anchored to the second concreting section 5b. An extension piece 32 is attached to the upper end of the first rail section 2a.Furthermore, a self-climbing drive 33, here with a linear drive, is brought into an attack position. After retracting into the second climbing shoe 3 above it, the pressure shoe 30 is removed from the ground (cf. . Fig. 3 and Fig. 4 ).

[0073] In a third step (see Fig. 4 The self-climbing drive 33 is activated to move the climbing rail 2 upwards. The trailing platform unit 23 tilts towards the unpivoted position, with the support roller unrolling on the floor 31.

[0074] In a fourth step (see Fig. 5 The first rail section 2a is fully raised to the level of the second concreting section 5b. The trailing platform unit 23 is in the non-pivoting position. The second rail section 2b extends downwards immediately following the lower end of the first rail section 2a. The first rail section 2a and the second rail section 2b are connected to each other via the locking device 26, which may, for example, include a locking bolt. The support roller at the lower end of the telescopic element 28 rolls along the outside of the first concreting section 5a.

[0075] In a fifth step (see Fig. 6 ) the wall formwork 8 is moved into a closed position in order to pour a third concreting section 5c directly above the second concreting section 5b.

[0076] Fig. 7 and Fig. 8 Figure 5d shows the production of a fourth concreting section after completion of the start-up phase. Any number of further concreting sections 5 can be produced accordingly. Fig. 7 is the wall formwork in the closed position, according to Fig. 8 arranged in the disclosure.

[0077] Fig. 9 and Fig. 10 show Fig. 7 and Fig. 8 corresponding views. However, greater floor heights are planned. For example, in this design, the concrete pouring sections 5a, 5b, 5c, 5d can have a height of 4.20 meters (versus 2.70 meters according to Fig. 7 and Fig. 8 ). In order to achieve optimal support with favorable leverage ratios, the telescopic element 28 is extended from the second rail section 2b.

[0078] As from Fig. 11 As can be seen, the support element 27 enables the climbing rail 2 to be guided in a single climbing shoe 3 as it climbs to the next concreting position. Only shortly before reaching the concreting position does the climbing rail move into a second climbing shoe 3.

[0079] For example, from Fig. 12 As can be seen, the first rail section 2a and the second rail section 2b of the climbing rail 2 are designed as hollow profiles 33 with a completely closed cross-section (viewed perpendicular to the longitudinal or climbing axis of the climbing rail 2). The hollow profile 33 has a substantially square cross-section with rounded corners 34, which are guided in corresponding recesses 35 in the inner contour of the climbing shoe 3 projecting plates. The hollow profile has a constant cross-section in the longitudinal direction of the climbing rail 2.

[0080] As can be further seen from the drawing, the four outer sides of the hollow profile 33 are arranged at an angle of essentially 45° to the vertical plane perpendicular to the outer side of the concreting section 5.

[0081] On two adjacent outer sides of the hollow profile 33, a plurality of longitudinally spaced, essentially horizontally extending retaining edges 36 are formed, on which claws 37 (cf. Fig. 14 bis 18 ) of the climbing shoe 3. In addition, a plurality of longitudinally spaced ramps 38 for the claws 37 of the climbing shoe 3 are provided on the same two outer sides of the hollow profile 33 to enable climbing up the climbing rail 2. Furthermore, two plate parts 39 are provided on the outer side of the hollow profile 33, each plate part 39 having recesses 40 for forming the holding edges 36 and ramps 38.

[0082] In the embodiment shown, the climbing shoe 3 has a base body 41 and two climbing shoe jaws 42, which are attached to the base body 41 between an open position (cf. Fig. 16 and Fig. 18 ) and a closed position (cf. Fig. 14 , Fig. 15 and Fig. 17 The climbing shoe jaws 42 are pivotably mounted. The closed position of the climbing shoe jaws 42 is used when climbing up the climbing rail 2 along the climbing shoe 3 and when supporting the climbing rail 2 on the climbing shoe 3. To remove and reposition the climbing shoe for the next concreting section 5, the climbing shoe 3 is moved into the open position. The climbing shoe jaws 42 each have a claw (or latch) 37, which holds one of the retaining edges 36 when the climbing rail 2 is supported.

[0083] In the embodiment shown, each climbing shoe heel 42 has a recess 43 into which a lateral corner section 33A of the hollow profile 33 is guided. The recesses 43 can each have a rounded corner, with correspondingly rounded lateral corner sections 33A of the hollow profile 33 being arranged in the recesses 43 with a substantially precise fit.

[0084] Furthermore, the climbing shoe 3 in the illustrated embodiment has a substantially vertical guide surface 44 on each climbing shoe jaw 42, in the illustrated embodiment a standing sheet, for one of the plate parts 39.

[0085] In the illustrated embodiment, the climbing shoe 3 has two locking elements 45, here designed as locking bolts, with which both climbing shoe jaws 42 can be secured against pivoting into the other position in both the open and closed positions. For this purpose, the base body 41 has a locking opening 46 on the vertical central or symmetry plane of the climbing shoe 3 and two further lateral locking openings 47. The climbing shoe jaws 42 have through-holes 48 which, in the closed position, are aligned with the locking opening 46 on the base body 41. One of the locking elements 45 is inserted through the aligned locking opening 46 on the base body 41 and the through-holes 48 on the climbing shoe jaws 42. This secures the guide jaws 42 together in the closed position by a single locking element 45.Furthermore, the climbing shoe jaws 42 have additional through-holes 49 which, in the open position, are aligned with the additional securing openings 47 on the base body 41. By arranging the securing elements 45 on the additional through-holes 49 of the climbing shoe jaws 42 and the additional securing openings 47 of the base body 41, the climbing shoe jaws 42 are fixed in the open position.

[0086] Fig. 19 bis Fig. 22 The figures show the process of the start-up phase in the construction of a building using a further embodiment of the climbing frame 1, with only the essential differences to the preceding embodiments being explained below.

[0087] The climbing rail 2 in turn comprises the first rail section 2a and the second rail section 2b, wherein the first rail section 2a is connected to the work platform unit 25 comprising the work platform 7 and the second rail section 2b of the climbing rail 2 is connected to the trailing platform unit 23 comprising the trailing platform 10. In the embodiment of the Fig. 19 bis Fig. 22 The second rail section 2b is designed as a telescopic element, which is telescopic relative to the first rail section 2a, i.e., it can be moved from a retracted to an extended state. The support element 27, in particular the support roller, is provided at the lower end of the second rail section 2b. By telescoping the second rail section 2b relative to the first rail section 2a, a height adjustment of the support element 27 is also achieved.

[0088] In a first step (see Fig. 19 The climbing shoe 3 is anchored to the first concreting section 5a. The climbing rail 2, along with the work platform unit 25 and the trailing platform unit 23, is then connected to the climbing shoe 3. The first 2a and the second rail section 2b are arranged in the collapsed position, overlapping longitudinally. The support roller at the lower end of the second rail section 2b is supported on the outside of the first concreting section 5a. Advantageously, this design requires less space on the side facing away from the first concreting section 5a compared to the previous embodiment with the joint 24 between the trailing platform unit 23 and the work platform unit 25.

[0089] In a second step (see Fig. 20 ) the first rail section 2a together with the work platform unit 25 is lifted, whereby the second rail section 2b is pulled downwards relative to the first rail section 2a.

[0090] In a third step (see Fig. 21 The climbing rail 2 is raised further when the second rail section 2b is extended. The second rail section 2b extends the first rail section 2a downwards.

[0091] In a fourth step (see Fig. 22 The first rail section 2a is fully raised to the level of a second concrete section 5b, which is positioned above the first concrete section 5a. The upper end of the first rail section 2a is connected to another climbing shoe 3 on the second concrete section 5b.

[0092] Fig. 23 bis Fig. 27 Figure 1 shows the initial phase of the construction of structure 4 using a further embodiment of the climbing frame 1, in which the climbing rail 2 additionally has a third rail section 2c for guiding it along the climbing shoe 3 on structure 4. The third rail section 2c is telescopically extendable upwards, i.e., in the longitudinal direction away from the support element 27, relative to the first rail section 2a.

[0093] In a first step (see Fig. 23 ) the first 2a, the second 2b and the third rail section 2c are arranged in the pushed-together state.

[0094] In a second step (see Fig. 24 ) the third rail section 2c is extended upwards relative to the first rail section 2a, whereby the self-climbing drive 33 is connected to the climbing rail 2.

[0095] In a third step (see Fig. 25 ) the second rail section 2b is pulled downwards relative to the first rail section 2a when climbing up the climbing rail 2.

[0096] In a fourth step (see Fig. 26 The climbing rail 2 is raised further when the second rail section 2b and the third rail section 2 are extended. The second rail section 2b extends the first rail section 2a downwards. The third rail section 2c extends the first rail section 2a upwards.

[0097] In a fifth step (see Fig. 27 ) the upper end of the third rail section 2c is connected to another climbing shoe 3 at the second concreting section 5b.

[0098] Fig. 28 bis Fig. 30 Figure 1 shows the construction of a structure 4 using a protective shield climbing frame 50 with a protective shield 51, which temporarily secures the edge areas of the floor slabs 4a of the structure 4. The protective shield climbing frame 50 has the climbing rail 2, which comprises the first rail section 2a, the second rail section 2b, and the third rail section 2c. The climbing rail 2 is guided in climbing shoes 3, which in this embodiment are attached to the floor slabs 4a via supports 52. In the embodiment shown, the protective shield 50 has a first shield element 51a on the first rail section 2a, a second shield element 51b on the second rail section 2b, and a further shield element 51c on the further rail section 2c.

[0099] Fig. 28 Figure 1 shows a first position in which the first rail section 2a and the second rail section 2b are arranged in a pushed-together state. This causes the first shield element 51a and the second shield element 51b to overlap longitudinally with the first rail section 2a. The third rail section 2c is extended relative to the first rail section 2a.

[0100] Fig. 29 shows a second position in which both the second rail section 2b and the third rail section 2c are extended relative to the first rail section 2a.

[0101] Fig. 30 shows a third position in which the second rail section 2b is extended relative to the first rail section 2a, but the third rail section 2c is pushed onto the first rail section 2a in order to adapt the height of the protective shield 51 to the structural conditions, here a protruding foundation plate 4b.

[0102] Fig. 31 bis 34 The climbing rail 2 is shown during the telescoping of the second rail section 2b relative to the first rail section 2a. If the third rail section 2c is present, the third rail section 2c can be telescoped relative to the first rail section 2a in the same way, so that the following explanations are to be transferred accordingly.

[0103] Fig. 31 The second rail section 2b, before reaching its extended position, extends downwards to extend the first rail section 2a. The second rail section 2b is moved downwards in the longitudinal direction of the first rail section 2a, i.e., when the climbing rail 2 is vertically oriented. The first rail section 2a has a front guide surface 53, which can slide along a corresponding guide surface of the climbing shoe 3. The second rail section 2a correspondingly has a front guide surface 54 for the guide surface of the climbing shoe 3. However, when the first 2a and second rail section 2b are retracted, the front guide surface 54 of the second rail section 2b is offset backwards relative to the front guide surface 53 of the first rail section 2a, i.e., away from the corresponding guide surface of the climbing shoe 3.This would make guiding the front guide surface 54 of the second rail section 2b in the guide shoe 3 more difficult or even impossible. For this reason, a guide device 55 is provided with which the second rail section 2b can be moved forward in a direction perpendicular to the longitudinal direction of the first rail section 2a so far that the front guide surface 54 of the second rail section 2b can be arranged in a plane with the front guide surface 53 of the first rail section 2a.

[0104] In the embodiment of the Fig. 31 bis Fig. 34 The guide device 55 has a sliding bearing for converting the telescoping, i.e., the extension movement, of the second rail section 2b into the forward displacement of the second rail section 2b. In the embodiment shown, the sliding bearing has at least one first sliding surface 56 on the first rail section 2a, inclined to the longitudinal direction of the first rail section 2a, and at least one second sliding surface 57 on the second rail section 2b, inclined accordingly to the longitudinal direction of the first rail section 2a. In the embodiment shown, two first sliding surfaces 56 are provided on the first rail section 2a and two second sliding surfaces 57 on the second rail section 2b, which are spaced apart from each other by the same longitudinal distances in the longitudinal direction of the first 2a and second rail section 2b, respectively. In the embodiment shown, the sliding elements with the second sliding surfaces 57 are... Fig. 31 bis 34 two wedge elements are provided.

[0105] Fig. 32 Figure 1 shows the contact of the second sliding surfaces 57 of the wedge elements on the second rail section 2b with the first sliding surfaces 56 on the first rail section 2a. This superimposes the lowering movement of the second rail section 2b relative to the first rail section 2a with a movement of the second rail section 2b perpendicular to it forwards.

[0106] Fig. 33 Figure 1 shows the completion of the forward displacement of the second rail section 2b, whereby the flat guide surface 54 of the second rail section 2b is now arranged in the same plane (here vertical) as the flat guide surface 53 of the first rail section 2a. The two first sliding surfaces 56 and two second sliding surfaces 57 cause a parallel forward displacement of the second rail section 2b.

[0107] Fig. 34 Figure 1 shows the achievement of the extended state. The second rail section 2b has a stop 58 which, in the extended state of the second rail section 2b, is abutted against a corresponding stop surface 59 on the first rail section 2a. This limits the downward telescoping of the second rail section 2b. Furthermore, the second rail section 2b has an upper retaining surface 60 which, in the extended state of the second rail section 2b, is arranged laterally to a corresponding upper retaining surface 61 of the upper sliding element on the first rail section 2a. Similarly, the second rail section 2b has a lower retaining surface 60 which, in the extended state of the second rail section 2b, is arranged laterally to a corresponding lower retaining surface 61 of the lower sliding element on the first rail section 2a. The retaining surfaces 60, 61 at the different longitudinal positions of the first 2a and 2b, respectively, are located on the first rail section 2a.The second rail section 2b forms a holding device which essentially blocks forward and backward movement of the second rail section 2b in the extended state (except for minimal play). Advantageously, this achieves a rigid arrangement of the second rail section 2b in the extended state.

[0108] In the version shown, the first rail section 2a and the second rail section 2b each have a double U-profile.

[0109] The Fig. 35 bis 38 Figure 1 shows an alternative embodiment of the climbing rail 2, in which the guide device 55 also has two sliding bearings. As in the preceding embodiment, the lower sliding bearing has a wedge element. The upper sliding bearing has an upper sliding surface 62 on the first rail section 2a, inclined to the longitudinal direction of the first rail section 2a, and a round element 63 on the second rail section 2b, which slides on the upper sliding surface 62. In the embodiment shown, the upper sliding surface 62 on the first rail section 2a is formed on an upwardly directed hook 64, which is provided on the rear side of the first rail section 2a.

[0110] Fig. 35 The second rail section 2b is shown before reaching its extended position, extending the first rail section 2a downwards. The second sliding surface 57 is spaced apart from the first sliding surface 56. The round element 63 is spaced apart from the upper sliding surface 62.

[0111] Fig. 36 Figure 1 shows the contact of the second sliding surface 57 of the lower wedge element on the second rail section 2b with the first sliding surface 56 on the first rail section 2a. Simultaneously, the round element 63 on the second rail section 2b slides along the upper sliding surface 62 on the first rail section 2a. This displaces the second rail section 2b forward relative to the first rail section 2a.

[0112] Fig. 37 shows the completion of the forward displacement of the second rail section 2b, whereby the front guide surface 54 of the second rail section 2b is now arranged in the same vertical plane as the front guide surface 53 of the first rail section 2a.

[0113] Fig. 38 Figure 1 shows the achievement of the extended state. The round element 63 is secured against lateral backward movement on the hook 64. Accordingly, in the extended state, the holding surface 60 of the lower wedge element on the second rail section 2b rests against the corresponding holding surface 61 of the first rail section 2a in such a way that horizontal displacement of the second rail section 2b is blocked.

[0114] The previously described variants of the climbing rail 2 can be used in the climbing formwork of the Fig. 19 bis 26 and at the protective shield climbing frame of the Fig. 28 bis 30 be planned.
