Description

Climbing Systems for Construction with Climbing Shoe or Guide Shoe {CLIMBING SYSTEM IN THE CONSTRUCTION COMPRISING A CLIMBING- OR GUIDE-SHOE}

The present invention relates to a climbing system for construction with a climbing shoe or a guide shoe.

It is known in the field of construction to use automatic climbing systems, in particular for the construction of multi-storey buildings, preferably high-rise buildings. Such automatic climbing systems are provided with the formwork necessary for the construction of the vertical walls of the building. As soon as the stretching walls have sufficiently hardened, a lift drive is supported on the wall via a suitable profile to lift the so-called frame unit supporting the formwork, resulting in a vertical wall being further "extended" in the upper region. It becomes possible. As soon as the stretch section is fully cured, the drive of the frame unit is "followed" upward while the vertical wall is erected, in order to lift the frame unit further from the stretch section.

Such a system is known from US Pat. No. 4,962,828. In this case, the frame unit does not necessarily have to have a formwork, but rather a safety net protruding outward from the building to be built, for example, to facilitate access to the new building including the roof to be placed on the new building. And / or a platform. The safety net and / or platform is installed in the frame unit. Additional profiles can be installed at individual points in the building, and a drive is provided that can be switched to lift a frame unit or profile provided for installation in the building.

Climbing formwork systems of the same applicant configured to be installed in buildings with a vertical profile capable of supporting a drive for lifting the frame unit are known under the name SKE. In another alternative operating position, the drive is supported on the frame unit, at which point the frame unit is hang-up and / or fixed to the building in order to be able to lift the vertical profile into a new section.

German Patent No. 10 2005 045 527 of the same applicant describes a protection and access device having a vertical profile, which is guided by a bracket which can be installed on an existing building roof. The bracket may be provided with a guide shoe for guiding the vertical profile.

U.S. Patent No. 4,530,648 describes a climbing system in which an emergency brake mechanism with a locking arm is configured to act on a rod in the lifting device.
U.S. Patent No. 4,838,382 describes a climbing system for a safety net with a climbing bracket, a climbing profile and a guide shoe that interacts with the climbing profile and is installed in a building. The guide shoe also has a friction brake.
British Patent Publication No. 2 366 828 A relates to an automatic climbing system with a climbing profile fixed to a building, in which case the climbing bracket is driven by a hydraulic drive and a toothed wheel on the basis of the climbing profile. Can be. Also mentioned are automatic brake systems.

An object of the present invention is to manufacture a climbing system for construction improved in terms of safety.

This problem is solved by the subject matter of patent claim 1.

According to patent claim 1, a climbing system provided with a climbing shoe or a guide shoe comprises at least one climbing bracket (kletterkonsole) and at least one climbing profile. The climbing profile can typically be installed in a building, as a result of which the climbing bracket is supported on the climbing profile for the purpose of ascending, and the climbing profile can be drawn with the climbing bracket installed in the building.

The climbing shoe or guide shoe can be installed in a building or climbing bracket. When a climbing shoe or a guide shoe is installed in a building, the shoe functions as a guide shoe. In an alternative case in which the climbing shoe or guide shoe can be mounted to the climbing bracket, the shoe functions as a climbing shoe if it has a latch or similar element that supports the shoe climbing bracket to the climbing profile. Relative motion occurs between the climbing profile and the climbing shoe when the climbing profile is raised or drawn. According to the invention, the climbing shoe or guide shoe is preferably provided with at least one brake which acts on the climbing profile directly and in a frictionally engaged manner. The brake prevents slipping or falling of the climbing profile in a preferred manner even in the event of a malfunction or in the event of a blocking latch or the like. In such situations, there is a risk of falling when the climbing profile is dragged if intentionally and accidentally engaged in the reciprocating device. At this time, the brake according to the present invention maintains the coupling state to fix the climbing profile even when there is a failure and / or malfunction in other safety devices.

The reliability of the brakes is increased by applying pretension to the climbing profile at least one brake. Thus, the brake remains in engagement with the climbing profile under the action of pretension, thereby ensuring the function described above.
Preferred improvements are described in further claims.

With regard to the engagement of the frictional engagement mode it has proved to be desirable if the at least one brake has at least one replaceable brake member. Thereby, the brake member, which must have special characteristics to fulfill its function, can be formed in a suitable manner, in which case the other members of the brake or other members of the climbing shoe or the guide shoe are formed in the same way as the brake. It doesn't have to be.

Especially good results have been tested in the case where the brake is implemented at least partially in steel, in particular when at least one replaceable brake member is implemented in steel as described above. In this way, not only the brake function but also the durability associated with the engagement of the friction engagement method can be ensured. A hardness of 50 HRC to 60 HRC, preferably 55 HRC to 60 HRC, and especially about 58 HRC, has been found to be preferred. In such hardness, advantageous braking action appears in the case where the quality of the roller is conventional, especially when interacting with a climbing profile that is formed significantly softer than the brake or brake member. In this case, it is preferable to wear the braking profile with a relatively long length when the braking operation is performed, but not with a brake having a relatively short length. It is further noted that the climbing profile and / or the brake and / or brake member may be formed of other materials suitable for each, and need not necessarily be implemented in steel.

With regard to the engagement between the brake and the climbing profile, it has also been found to be advantageous to have the climbing profile have at least one flange so that at least one brake acts on the edge of the flange.

In addition, in the present embodiment, for the coupling between the flange of the climbing profile and the climbing shoe or the guide shoe, it is preferable that the flange is engaged with the at least one guide member of the brake at the rear so that linear contact is made between the at least one guide member and the climbing profile. Do. This allowed us to reach particularly good characteristics during the test run.

It is particularly preferable when the climbing shoe described above can be installed in the climbing bracket as the lower climbing shoe of the two climbing shoes. Thus, the advantage that the braking force can be overcome if the lower climbing shoe is dragged in the operating state in which the climbing bracket is raised. In this case, relatively little power can be provided, so that a conventionally reserved spare (hydraulic-driven) drive device is sufficient to overcome the braking force. In the operating state where the climbing profile is being dragged, the braking force must be overcome as well. In any case, however, the climbing profile is lighter than the climbing brackets, and consequently, in this case, a spare drive is enough to overcome the braking force. At the same time, however, the safety improvement as described above can also be achieved by always engaging the brakes.

In a preferred embodiment the climbing profile can be installed in the building and the climbing shoe can be installed in the climbing bracket. Thus, when the climbing profile is dragged, the above-described braking function appears to prevent the climbing profile from slipping or falling.

In an alternative embodiment, the shoe may be installed in a building as a breaking-guide shoe. As a result, even when the climbing profile is raised, continuous braking of the climbing profile can be achieved, and as a result, safety is increased in this case.

It is also preferable for the climbing system according to the invention that the climbing bracket of the climbing system has a double profile, in which case the climbing profile can be arranged between the individual profiles of the double profile. Thereby, the entire climbing bracket can be installed particularly close to the building, and the power resulting from the torque can be reduced in a desirable manner. This situation makes it possible to implement a thinner, longer and lighter profile of the climbing bracket, preferably reducing the weight. The double profile also forms a kind of "frame" around the climbing profile, in which the upper climbing shoe can be integrated, in particular in a space saving and accessible manner.

Detailed Description of One Preferred Embodiment of the Invention
The structure of the climbing shoe or the guide shoe according to the invention is in the form of a housing having one upper surface 30 and two side walls as a whole, the two side walls being formed by a brake 18 to be described below. One of the two side walls is covered by the climbing profile 14. In the illustrated embodiment, the upper surface 30 is provided with two lugs 32 each having openings 34, by which the climbing shoe is driven as described in detail below. Is connected to. The brakes 18 each have one guide member 36, which engages with the flange 16 of the climbing profile at the rear. In the illustrated embodiment, the guide member 36 is said to be formed in a dual wave form, so that linear contact with the climbing profile is made in the region of the wave trough facing inward. In the case shown, the wave troughs are present in the upper and lower regions of the guide member 36, respectively.

At the edge of the flange (not shown in FIG. 1), a brake member 20 in the form of a strip acts, which in each of the illustrated embodiments are interchangeably installed on the brake 18. In the example shown, a disc spring packet 38 is provided which allows the brake 18 to apply pretension to the climbing profile 14. In particular, since the brakes 18 are pretensioned in the direction in which they merge with each other, the climbing profile 14 consequently "tightens" between the brakes. Since the brake 18 can move in the horizontal direction, it is advantageously possible to compensate for the dimensional tolerances that may appear in the climbing profile, and furthermore to keep the climbing shoe approximately in the center of the engagement area of the latch described below. have. In the illustrated embodiment the pretension is applied not only to the lower region of the brake 18 by the disk spring packet 38 but also to the upper region.

Inside the climbing shoe shown in FIG. 2, one latch 40 of the two latches is visible, and when the climbing bracket is lifted, the climbing shoe is supported in the climbing profile by the latch. It should be noted that the climbing profile 14 shown in the figure is implemented as an I-profile, in this case a flange with an opening 44 on the other side of the intermediate bar 26 as well. There is an extension of 16). In this area the climbing shoe is provided with an additional latch. In addition, there is an additional brake in this region, which is formed approximately mirror symmetrically with respect to the brake 18 as seen in FIG. 1. In an alternative operating state in which the climbing profile is to be dragged, the power transfer between the drive profile provided on the climbing bracket and the climbing profile is also made through the latch.

2, the interaction between the latch 40 of the climbing shoe 10 and the climbing profile can be seen more clearly. In the upper region of FIG. 2, it can be seen that the protrusion 32 of the climbing shoe 10 is provided with a driving device 42 in the form of a hydraulic cylinder. In the operating state in which the climbing bracket is installed in the building, the lower guide shoe 10 shown in FIG. 2 may be raised by pulling the hydraulic cylinder 42. In this case, the latch 40 is inserted into the opening 44 formed in the climbing profile 14 so that the upper edge of the latch engages with the climbing profile 14. Such coupling can of course also be achieved through a protruding cam or the like. The latch 40 is moved to the position shown in the figure by the shift lever 46. In order to allow the lower climbing shoe 10 to move down relative to the climbing profile 14, the engagement between the shift lever 46 and the latch 40 is elastic. This process is carried out when the hydraulic cylinder 42 is fully inserted and the climbing profile is fixed to the upper climbing shoe, which is started to be lifted further by using the withdrawal motion of the hydraulic cylinder 42. It is for sending the climbing shoe 10 to the position. It can be seen in FIG. 2 that the latch 40 prevents the climbing profile 14 from falling down. However, this fall protection does not apply to malfunctions or other abnormal events, so in that case the brake according to the invention acts in one direction perpendicular to the projection plane with respect to the flange of the climbing profile with the opening. Falls are prevented by

The direction change of the latch device is achieved by turning down the direction change lever 46 to pass through a dead point. Thereby the lower edge of the latch 44 is then engaged with the climbing profile 14, whereby the climbing shoe 10 can be supported by the climbing profile 14 installed in the building in its operating state. The climbing bracket is lifted by the withdrawal of the hydraulic cylinder 42 in the supported state. The climbing shoe 10 is then pulled up so that the climbing shoe is moved to a higher position where an additional climbing step of the climbing bracket can begin.

For clarity, the climbing bracket 12 is shown in FIG. 3 as having a vertical profile formed of double profiles 48, 50 on the side facing the building (not shown in the figure). The upper surface of the climbing bracket 12 is provided with a horizontal profile 52, for example, a slide is installed on the horizontal profile so as to be movable in a horizontal direction, whereby a form member provided on the slide. Can be sent to a location for applying concrete to the wall. The support operation of the vertical profile 52 is made by the diagonal support 54.

In the upper region of FIG. 3, the upper climbing shoe 28 installed in the bracket 12 can be seen. The upper climbing shoe is connected to the lower climbing shoe 10 via a drive of the hydraulic cylinder 42. In the illustrated embodiment, the climbing profile 14 is accommodated between the profiles 48, 50 of the vertical profile of the climbing bracket 12 and is somewhat surrounded by the vertical profile. As such, the entire apparatus, as described above, is installed particularly close to the building in order to keep the power and moment generated small. For a complete configuration the individual profiles 48, 50 of the vertical profile of the climbing bracket 12 were formed as I-profiles in the example shown, with the middle bars of the I-profiles respectively extending to the extension of the horizontal carrier 52. Proceed in a generally parallel direction. This shape applies equally to the climbing profile of the illustrated embodiment. In the embodiment shown, the openings 44 are provided in two rows on the flange facing the climbing bracket 12 on the opposite side of the building, and only one row of openings are visible in the figure. As described above, two latches arranged side by side of the climbing shoes 10, 28 are inserted into the opening. Complementaryly speaking, the lower region of the climbing bracket 12, not shown in the figure, may be provided with a supplementary guide shoe for guiding the climbing profile.
