Description

Climbing or guiding shoe of a climbing system in construction and climbing system with such a climbing or Forsung shoe

Technical area

The invention relates to a climbing or guide shoe of a climbing system in construction and a climbing system with such a climbing or guide shoe.

In particular, for the creation of multi-storey, preferably particularly high buildings, it is known in the field of civil engineering to use self-climbing systems. On these the formwork are provided, which are required for the creation of vertical walls of the building. As soon as the newly created walls are sufficiently hardened, lifting drives are supported by suitable profiles to lift the so-called scaffolding units that support the formwork so that the vertical walls can continue to "grow" in an area above. As these walls are being created, the scaffold assembly drives are "retraced" upward to further raise the scaffold assembly from the newly created portion as soon as it has sufficiently hardened. State of the art

Such a system is known from US 4,962,828. In this case, the scaffolding unit does not necessarily have formwork, but, for example, a safety net projecting outwards from the building to be constructed, and / or platforms for access to the building to be constructed, including ceilings to be created therefrom. The latter elements are attached to the scaffold unit. Other profiles are attachable to individual parts of the structure, and a reversible drive is provided to raise either the scaffolding unit or the profiles intended for attachment to the structure.

Under the name SKE a climbing formwork system of the applicant is known in which vertical profiles, on which the drives can be supported for lifting the scaffold unit, are attachable to the building. In an alternative operating position, the drives are based on the scaffolding unit, which is suspended and / or anchored to the building at this time in order to be able to lift the vertical profiles in a new section.

DE 10 2005 045 527 of the applicant describes a protection and access device having vertical profiles which are guided by cantilever beams, which are attachable to existing building ceilings. On the cantilevers may be provided to guide the vertical profiles guide shoes.

US 4,530,648 describes a climbing system in which an emergency braking mechanism having locking arms acts on a rod within the lifting mechanism. Presentation of the invention

The invention has for its object to provide a climbing or guide shoe climbing a system in construction as well as equipped with a climbing system, which is improved in terms of safety.

The solution of this object is achieved by the subject matter of patent claim 1.

Accordingly, the climbing system for which the climbing or guide shoe is provided has at least one climbing console and at least one climbing profile. The climbing profile is usually attached to a structure, so that the climbing console is supported for climbing on the climbing profile, and the climbing profile in the state that the climbing console is attached to the building, can be tightened.

The climbing or guide shoe can be attached to a building or the climbing console. In the case that the shoe is attachable to a building, it acts as a guide shoe. In the alternative case that the shoe is attachable to the climbing console, it acts as a climbing shoe insofar as it is provided with pawls or similar elements, over which the climbing console is supported on the climbing profile. When climbing and when tightening the climbing profile there is a relative movement between the climbing profile and the climbing shoe. According to the invention, at least one preferably directly and preferably frictionally acting on the climbing profile brake is provided on the climbing or guide shoe. This brake advantageously prevents slipping or crashing of the climbing profile, even at Operating error or failure of pawls or the like. In such situations, or if willfully and incorrectly intervened in the lifting mechanism, there is a risk that the climbing profile crashes when tightening. Here, the brake according to the invention intervenes and holds the climbing profile even in the case that others

Safety mechanisms fail and / or there is a user error.

The brake can act directly and / or directly on the climbing profile. However, it is also an indirect action conceivable, for example by means of a safety rope or an arrangement in which the climbing profile drives in its movement, for example, a pinion, which is connected to a viscous coupling. By means of all such arrangements, a crash of the climbing profile can be prevented in an advantageous manner, so that the security is significantly increased.

Preferred developments are described in the further claims.

The reliability of the brake is increased by the fact that at least one brake is biased against the climbing profile. The brake is thus constantly engaged with the climbing profile under bias and thereby ensures the function described above.

With regard to the frictional connection, it has proved to be advantageous if at least one brake has at least one replaceable brake element. As a result, the brake element, which must be provided for the fulfillment of its function with special properties, suitable Be fashioned without this being required for other parts of the brake or the climbing or guide shoe.

In tests, particularly good results have been achieved when the brake is at least partially, in particular at least one replaceable brake element, as described above, made of particularly hard steel. As a result, both the braking function and the durability in view of the frictional connection can be ensured. A hardness of 50 HRC to 60 HRC, preferably 55 HRC to 60 HRC and in particular about 58 HRC has proven particularly advantageous. With such a hardness results in a favorable braking effect, especially in the interaction with a climbing profile in a usual rolling quality, which is correspondingly softer than the brake or the brake element. Here occurs in an advantageous manner, when braking, the wear on the comparatively long climbing profile and not on the relatively short brake. It should also be noted that the climbing profile and / or the brake and / or the brake element may be formed of another material suitable for this purpose and does not necessarily have to be made of steel.

With regard to the engagement between the brake and the climbing profile, it has also been found to be favorable to form the climbing profile with at least one flange, acting on the edge of which at least one brake.

Further, for the connection between the climbing or guide shoe and the flange of the climbing profile in this embodiment, it is preferred that the flange of at least a guide element of the brake is engaged behind, and between at least one guide element and the climbing profile is a line contact. As a result, particularly good properties could be achieved during the test operation.

As mentioned, the invention further relates to a climbing system with at least one climbing or guide shoe in one of the preceding embodiments.

It is particularly advantageous if the climbing shoe described above can be attached to the climbing console as the lower of two climbing shoes. This results in the advantage that the braking force is then overcome when the lower climbing shoe is retightened in the operating condition that the console is raised. In this case, comparatively small forces have to be applied, so that the usual reserves of the (hydraulic) drives are sufficient to overcome the braking forces In the operating state in which the climbing profile is retightened, the braking force must also be overcome However, in any case lighter than the climbing console, so that in this case the reserves of the drives are sufficient to overcome the braking force.At the same time, however, can be achieved by the continuous intervention of the brake, the described improvement in safety.

In a preferred embodiment, the climbing profile is attachable to a building, and the climbing shoe on the climbing console. This results in the described braking function when tightening the climbing profile to prevent it from slipping or falling. In an alternative embodiment, the shoe can be attached to a building as a brake guide shoe. As a result, a constant braking of the climbing profile when lifting the same can also be done, so that here too safety is increased.

For the climbing system according to the invention is further preferred that the climbing console has a double profile, between the individual profiles of the climbing profile can be arranged. As a result, the entire climbing console can be brought particularly close to the building, and the forces resulting from the torques can be reduced in an advantageous manner. This allows a slimmer and lighter version of the profiles of the climbing console and leads to an advantageous weight reduction. The double profile also forms a kind of "frame" around the climbing profile, in which the upper climbing shoe can be integrated particularly space-saving and easily accessible.

To the above-described embodiment of Kletterkonεole with a double profile is to emphasize that this embodiment is independent of the brake described above, and also without this brake, but optionally in combination with this and / or one or more of the features described above and below advantages unfolded and thus be regarded as the subject of the application.

Detailed description _in a preferred embodiment of the invention

Overall, the structure of the climbing shoe or guide shoe according to the invention is in the nature of a housing with a top 30 and two side walls or cheeks formed by the brakes 18 described below, one of which is covered by the climbing profile 14. On the upper side 30, two tabs 32 are provided with respective openings 34 in the case shown, by means of which the climbing shoe, as described in more detail below, is connected to a drive. The brakes 18 each have a guide element 36 which engages behind a flange 16 of the climbing profile. In the embodiment shown, the guide elements 36 are designed to be somewhat doubly wave-shaped, so that there is a line contact with the climbing profile in the region of the inwardly directed wave troughs. These troughs are in the case shown in each case in the region of the upper and lower end of the guide member 36th

On the edge of the flange act {in Fig. 1 unrecognizable) strip-shaped brake elements 20, which are mounted in the case shown in each case replaceable on the brakes 18. In the case shown disc spring packages 38 are provided to bias the brakes 18 against the climbing profile 14. In particular, the brakes 18 are biased toward each other in one direction, so that the climbing profile 14 is "sandwiched" between them. The mobility of the brakes 18 in the horizontal direction advantageously makes it possible to compensate for the dimensional tolerances which can occur on the climbing profile and, moreover, ensure that the climbing shoe always remains approximately centrally in the engagement region of the pawls described below. In the example shown, the bias is provided by means of the disc spring assemblies 38 both in the lower and in the upper region of the brakes 18.

In the interior of the climbing shoe in Fig. 2 one of two pawls 40 can be seen, by means of which the climbing shoe is supported on the climbing profile when the climbing console is to be raised. It should be mentioned at this point that the climbing profile 14 is designed in the case shown as an I-profile, and on the other side of the central web 26 is the continuation of the flange 16, which is also provided with openings 44. In this area, a further pawl is provided on the climbing shoe. Furthermore, there is in this area a further brake, which is designed in approximately mirror image to the brake 18 to be recognized in FIG. In the alternative operating condition, when the climbing profile are retightened should, the power transmission between the provided on the climbing console drive and the climbing profile also done via this latch.

From Fig. 2, the interaction between the pawls 40 of the climbing shoe 10 and the climbing profile is even clearer. In the upper area of FIG. 2, it can first be seen how a drive 42 in the form of a hydraulic cylinder is provided on the lugs 32 of the climbing shoe 10. In the operating state in which the climbing console is attached to a building, by drawing in the hydraulic cylinder 42, the lower guide shoe 10 shown in FIG. 2 can be raised. The pawl 40 engages with an upper edge with the climbing profile 14 by protruding into an opening 44 formed therein. It should be noted that this intervention can of course also be made on projecting cams or the like. The pawl 44 was brought by means of a switching lever 46 in the position shown. The connection between the switching lever 46 and the pawl 40 is resiliently formed to allow the lower climbing shoe 10 to move downwardly with respect to the climbing profile 14. This is done when the hydraulic cylinder 42 is fully retracted, and the climbing profile is held on the upper climbing shoe to bring the climbing shoe 10 by extending the hydraulic cylinder 42 to a position from which the climbing profile 14 can be raised further. In Fig. 2 it can be seen that a crash of the climbing profile 14 is prevented downwards by the pawl 40. However, this does not apply to operating errors or other unusual events, so that in this case the brake according to the invention, which in a direction perpendicular to the plane of the drawing with the openings provided flange of the climbing profile acts to prevent a crash.

The conversion of the pawl mechanism is carried out by pivoting the Umstellhebels 46 down over a dead center. As a result, the pawl 44 is below with its lower edge with the climbing profile 14 into engagement, so that the climbing shoe 10 can be supported on the climbing profile 14, which is mounted in this operating condition on the building. In the corresponding support is carried out by extending the hydraulic cylinder 42 lifting the climbing console. By subsequent tightening of the climbing shoe 10 upwards this is brought into a higher position, starting from which a further climbing step of the console can be done.

3, the climbing console 12 is shown, which has a vertical profile designed as a double profile 48, 50 on its side facing the structure (not shown) may be slidably mounted in a horizontal direction in order to bring the formwork elements provided thereon into a position for concreting walls. The vertical profile 52 is supported by a diagonal support 54.

In Fig. 3, an attached to the console 12 upper climbing shoe 28 can be seen in the upper part. This is connected via the drive of a hydraulic cylinder 42 with the lower climbing shoe 10. In the example shown, the climbing profile 42 is received between the profiles 48, 50 of the vertical profile of the climbing console 12 and surrounded by this as it were. This can be as above described, the entire arrangement be brought particularly close to the building to keep the forces and moments occurring low. For the sake of completeness, it should be mentioned that the individual profiles 48, 50 of the vertical profile of the climbing console 12 are designed as I-profiles in the case shown, whose center webs each extend in a direction which is substantially parallel to the extension of the horizontal beam 52. This design applies in the example shown in the same way for the climbing profile. On the flange, which faces away from the building and thus points to the climbing console 12, two rows of openings 44 are provided in the example shown, of which only one row can be seen. Two juxtaposed pawls of the climbing shoes 10, 28 engage in these openings, as described above, a. It should be added that in a lower portion of the climbing console 12, not shown, a complementary guide shoe for guiding the climbing profile can be provided.
