Description

Self-climbing system and method for concreting a sub-assembly and / or assembling a product by means of a self-climbing system

Technical area

The invention relates to a self-climbing system in the field of civil engineering and to a method for concreting a substructure and / or mounting a precast element by means of a self-climbing system.

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. These are the formwork that is required for the creation of vertical walls of the building. As soon as the newly finished walls are sufficiently hardened, lifting drives are supported by suitable profiles to lift the so-called scaffolding units, which 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

In DE 10 2006 026 201 the Aniuelderin such a self-climbing system is described.

Furthermore, DE 10 2005 045 527 of the applicant relates to a protection and access device which can similarly climb and serve to secure a not yet provided with a facade outdoor area of a building and to provide an access connection between adjacent floors of the building,

Presentation of _, invention

The invention has for its object to improve a self-climbing system in the field of civil engineering in terms of applications. Furthermore, a simplified method for concreting a beam and / or mounting of a finished part is to be created.

The solution to this problem is on the one hand by the self-climbing system according to claim 1.

Accordingly, this has at least one horizontal support, which is adapted for the support of at least one finished part and / or at least one formwork. As is known to those skilled in the art, a self-climbing system of the basic type usually consists of a plurality of vertical profiles, by means of which the self-climbing system can be suspended from suspension points on the building. Furthermore, the lifting of the self-climbing system takes place, for example, by a crane, which acts on one or more vertical profiles, or by means of one or more drives which, between the building, in particular the suspension points provided thereon, and the vertical profiles act. On the side facing away from the building, one or more largely horizontal support may be provided on which, for example, work platforms or platforms may be provided. Further formwork can be slidably provided in the horizontal direction on the Horizontalträgem to create the outer walls of the building.

The inventively provided horizontal beam, which is provided for the support of at least one finished part and / or at least one formwork, differs from these previously provided horizontal beams insofar as it protrudes in the direction of the building to be created. In the position in which it allows the support of a finished part and / or formwork, it is at least largely aligned horizontally. The horizontal beam typically projects not only toward the structure, but into it insofar as it extends, as seen in elevation, into areas in which columns and / or ceilings of the structure may be present. In this area, that is, for example, between columns that are provided in the area of the later outer walls, it may be desirable in certain applications to mount beams as precast, or to concretise them by means of suitable formwork. Here, the self-climbing system according to the invention enables the corresponding work steps, by providing a possibility for assembling a finished part and / or for concreting a beam to a self-climbing system, which may be provided as already required protection and access device. The horizontal support may be provided for example as an I-beam and along its longitudinal extent a plurality of mounting holes exhibit. However, it can also be designed as a double I-profile. To support a formwork can be mounted on one or more horizontal beams largely extending transversely thereto formwork beams to which in turn shuttering panels can be firmly attached. To support a finished part, an assembly aid in the form of a holder, which can cooperate with a further holder provided, for example, on the vertical profile, can be present on one or more horizontal carriers.

The requirement to "weiterklettern" after the assembly of the finished part or after stripping the beam, although the horizontal beam initially projects into an area of the building in which above now a beam and possibly ceilings are, is taken into account that the Horizontal support is pivotally mounted on a vertical profile of the self-climbing system. In this way, it can be swung out into the largely horizontal position described in order to enable the described support of a finished part or formwork. After the assembly of the finished part has been completed or the formwork has been removed, the horizontal beam can be pivoted away from the building and into the area of the self-climbing system, so that there is no risk of collision with existing beams, ceilings and the like, and further climbing becomes possible. Here, the advantage can be maintained, which results from the above-mentioned "protection and access device", namely that with a single vertical profile plane, which is comparatively close to the building, all functions in terms of climbing and wearing the desired formwork, platforms and protection and access devices can be realized. With regard to the assembly of a finished part, such as a beam prefabricated part, as well as with respect to the sheathing of a beam, the self-climbing system according to the invention has the advantage that the processes are simplified. To date, it has been necessary to convert those slab formwork tables used to cover the ceilings, to allow the sheathing of a beam or the support of a suitable finished part. The slab tables can now advantageously remain unchanged and be transported to the next higher level, while the assembly or concreting of a beam can be made by the self-climbing system according to the invention.

It should be mentioned that the horizontal support provided according to the invention can also be provided on the vertical profile of the self-climbing system such that it can be displaced in the direction of the building. Also in this way, the horizontal support can be brought into that position in which it allows the support of a finished part and / or a formwork. Similar to pivoting back a pivotal horizontal beam, a sliding horizontal beam can be quickly and easily retracted from the structure to allow for further climbing.

Preferred developments of the self-climbing system according to the invention are described in the further claims.

For the rapid adjustment of the height of the horizontal beam in the vertical direction, it has proved to be advantageous proven to mount the horizontal beam on a carriage which is displaceable along the vertical profile of the self-climbing system.

Here, furthermore, the displacement position of the carriage along the vertical profile by means of a spindle can be adjusted continuously. In other words, a spindle between a fixedly provided on the vertical profile support and the carriage may be present, on which the horizontal support is mounted. As a result, the vertical position of the carriage and thus of the horizontal support can be adjusted quickly and efficiently. It should be noted that this is, so to speak, an "indirect" attachment of the horizontal support on the vertical profile, namely by means of the carriage located therebetween.

Advantageously, the pivoting of the horizontal support can be accomplished "mechanically" by using at least one detachable drive which can be attached to the horizontal support. The drive may, for example, act between the horizontal support and an attachment point on the carriage mentioned above. As a result, a unit is created, which can be adjusted by means of the described spindle with respect to the vertical support in height. The swinging in and out of the horizontal carrier can be made in a particularly simple manner by the described drive. In an advantageous manner, this may be a drive which is provided on the self-climbing system anyway, in order to raise it with respect to the structure. Here, the drive is supported at suitable points on the structure and gradually raises the self-climbing system. As in the above-mentioned DE 10 2005 045 527 of the applicant executed, the corresponding drives can be removable, so that they can be used on the self-climbing system according to the invention in an advantageous manner for swinging in and out of the horizontal carrier. It should be noted that the disclosure of the applicant's DE 10 2005 045 527 with regard to the drives, the climbing operations and the support to the building by the reference fully made the subject of the present application. This applies equally to the guide shoe described in DE 10 2007 018 851 of the applicant and to the self-climbing system described in DE 10 2006 026 201 of the applicant with regard to the climbing operations and the support on a building.

It has also proved to be advantageous to attach at least one platform to the horizontal beam. This platform can in particular replace that area of a platform already present on the self-climbing system, which must be recessed and / or removed in order to enable the described pivoting in of the horizontal carrier. In order to create the space required for swiveling in the area of the existing platform and at the same time bring the existing platform as far as possible to the building, in particular the finished part to be supported or the beam to be scarfed, a platform can be provided on the horizontal beam.

For the support of a finished part in the context of its assembly or for the support of at least one formwork by means of the horizontal support, it may be necessary due to the forces occurring, the horizontal support in addition to its attachment to the vertical profile in addition support. This can be done for example by one or more supports between the horizontal beam and an already created building ceiling. Advantageously, these columns can be stored after the pivoting of the horizontal beam for Weitererkletter the self-climbing system on a stage of Selbstklettersystems to be lifted together with this and placed in a position in which a beam of an overlying level can be mounted and / or switched ,

In the event that the horizontal beam according to the invention is used to support a formwork, it also offers advantages to support the formwork by means of at least one support. This is particularly useful between two adjacent horizontal beams. In this connection, it should be mentioned that any formwork carriers which can be attached to two or more horizontal carriers and run transversely thereto must be interrupted in order to enable the horizontal carriers to swing in "alongside" the respective vertical profile. In other words, such formwork supports are interrupted in the region of the vertical profiles. In these areas, a support of the formwork by means of the above-mentioned additional supports offers. Advantageously, these supports can also stand after pivoting the horizontal beams, so that the horizontal beams at a time when the concrete is not fully cured, can already be pivoted, and the system can be prepared for Weitererklettern. The further required support of the not yet fully cured concrete is done by the described additional supports. At least one of the supports described can in a first embodiment a demountable console in a simple manner for support have an oäer several horizontal carrier. In this case, the support initially serves both to support the not yet fully cured concrete and, by means of said console, for supporting at least one horizontal support. Preferably, it is arranged between two horizontal carriers. After dismantling the described console, the horizontal beams can be swung in, and the support can remain in place until the concrete is completely cured. According to a second embodiment, the support is adapted to directly support the horizontal beam. For example, two columns can be used here. At a time when the concrete has not yet fully cured, first a support for supporting the not yet fully cured concrete may preferably be arranged centrally between two horizontal beams, and subsequently the second support can be removed from the horizontal beam to swing it. Thus, the not yet fully cured concrete is supported at all times.

Furthermore, it offers considerable advantages for the construction progress when the self-climbing system according to the invention has a part of a column formwork. For this purpose, it should be explained that the construction progress usually takes place in such a way that first the pillars of the building, some of them in the area of the later outer walls, are concreted, subsequently the necessary drawstrings are formed between the pillars, and in a further step the roofs are concreted , If the self-climbing system according to the invention comprises a part of a column formwork, preferably a facade-side part of a column formwork, this part can serve as a template for the reinforcements be used so that they can be introduced at a very early stage. Immediately, after the remaining three sides of the column formwork, for example, have been implemented, concreting of the respective column can be started.

To solve the above object, a method for concreting a beam and / or for mounting a precast element with the features of claim 9 is further presented. The method, which is repeated several times to create a multi-storey building, brings the swinging a horizontal beam for supporting a precast or formwork in a largely horizontal position, the shelling and concreting a beam or the mounting of a precast and the (back) pivoting of the Horizontal carrier with itself. As a result, an efficient method for the formation of beams is created.

The further advantages and preferred refinements of the method according to the invention predominantly correspond to the preferred embodiments of the self-climbing system described above.

Detailed description of a preferred embodiment of the invention

As can be seen in FIG. 1, the self-climbing system according to the invention has one or more vertical profiles 18, of which, however, only one vertical profile 18 can be seen in the side view of FIG. Further such vertical profiles may be located "behind" or "before" the vertical profile 18 shown in the viewing direction of FIG. 1. Suitable shoes 30, of which at least two are provided along the height, and which in the case shown are designed as slipper shoes, since they are attached to an already created building ceiling 32, the support of the system takes place on the building. The attachment to the shoe 30 takes place, in particular, by means of so-called climbing cams 34. Furthermore, a detachable drive, for example in the form of a hydraulic cylinder, can act on this climbing cam 34 in order to lift the self-climbing system. For details, reference is made to the above referenced applications. On the vertical profile 18 various extending away from the building platforms 36 are provided, which interposed supports may be supported on beams 38, which in turn are attached to the vertical profile 18. For safety reasons, railings 40 are preferably located in the rear area of the platforms 36.

In a novel way, a Horizσntalträger 12 is further provided, which extends in the direction of the building and is pivotally mounted on the vertical profile 18. In the embodiment shown, this pivotal mounting is carried out on the top of the horizontal beam 12 and on a carriage 20 whose height position along the vertical profile 18 by means of a spindle 22 is adjustable, on the one hand to the carriage 20 and on the other to one attached to the vertical profile 18 Support 42 is attached. The carriage 20 extends over a certain height along the vertical profile 18 and has, in addition to the attachment point for the spindle 22, which is provided in its lower region, in particular at its lower end, an attachment point 44 provided in the upper region, preferably at the upper end for a removable drive 24 in the form of a hydraulic cylinder. The horizontal beam 12 extends in the direction away from the building a certain distance beyond the vertical profile 18 addition. In this area, the drive 24 can be mounted so that the horizontal support 12 can be switched on and swung out with a certain degree of leverage.

In Fig. 1, the swung-out position is shown, in which the horizontal support 12 is in a substantially horizontal orientation and in the case shown via two formwork beams 46, a formwork panel 14 and a side formwork 16 is supported to concrete a joist 48 to be able to. In the case shown, a diagonal support 28 is further attached to the horizontal support 12. In the situation shown, the further support is additionally provided by a vertical support 50. It can also be seen in FIG. 1 that a platform 26 is provided in the region of the horizontal support 12 which faces away from the building. This complements the platform 36, which is recessed in the area below the provided on the horizontal beam 12 platform 26 to allow the pivoting of the horizontal beam 12. Furthermore, the described "shortening" of the platform 36 facilitates the operation of the spindle 22 for the continuous adjustment of the height position of the carriage 20 and thus of the horizontal support 12th

The pivoted position is shown in Fig. 2. The drive 24 in the form of a hydraulic cylinder has been retracted, and by an upward pull on the remote from the building end of the horizontal beam 12, this was about its pivot point, which is provided in the example shown on the carriage 20 in one direction pivoted clockwise. In the fully pivoted position shown in Fig. 2, the horizontal support, for example, largely aligned vertically. Thus, the clambering is no longer hindered. In other words, the self-climbing system can pass by the existing building ceilings 32 and the freshly-concreted undercarriage 48. In the embodiment shown, it can also be seen that the formwork beams 46 and the formwork panel 14 can remain mounted on the horizontal beam 12. Advantageously, the side mold 16 can be placed on the platform 36 of the self-climbing system 10 and lifted together with this to the next level. This applies in the same Way for the two supports 28, 50, which may be stored for example on the platform 36 of a lower level.

It can also be seen from Fig. 2 why the platform 36 should be recessed in the (upper) area in which the horizontal beam 12 is located at the end facing the building. When swinging out of the horizontal support 12 moves in this area and is in particular, as shown in Fig. 2, for example, at the building end of the platform 36 at. Through the recess of the platform 36, the space required for this purpose is created. At the same time, the platform 26 provided on the horizontal support 12 continues the platform 36 in the direction of the building (see Fig. 1).

In Fig. 3 is shown in addition, as the self-climbing system according to the invention can also be used for mounting a precast element 52. The situation shown in Fig. 3 corresponds substantially to that of Fig. 1. At the horizontal beam 12, however, mounting aids 54 are attached, which hold the precast member 52, which forms a beam during mounting and support. The horizontal support 12 may be referred to as a support for the finished part 52 extent. In the embodiment shown, another mounting aid 56 is attached to the vertical profile 18. With these additions, the self-climbing system according to the invention can thus be used in an advantageous manner for supporting the finished part 52, in particular during its assembly.

4 shows the self-climbing system according to the invention additionally in a plan view. Here, the vertical profiles are again denoted by ^{! I} 18 ", and it is it can be seen that two horizontal supports 12 are located adjacent to each vertical profile 18. At two horizontal beams 12, two formwork beams 46 are mounted, which are interrupted in the region of the vertical profiles 18 to the pivoting of the horizontal beams 12 including the formwork beams 46 and attached thereto

To allow shuttering panels 14 (see Fig. 1). This space in the area of the vertical supports 18, in which the formwork beams 46 are interrupted, can be advantageously used for setting up supports 58, with which further formwork panels, which cooperate with the formwork panels 14 (see FIG In particular, the formwork panels supported by the supports 58 can remain while the remainder of the created beam is already turned off and the horizontal beams 12 are pivoted back, since some support is still provided by the supports 58, the remaining stripping and pivoting back of the horizontal beams 12 can be achieved advantageously take place very early, so that no unnecessary delays arise.

This applies in the same way for the further measure, according to which a part 60 of a column formwork is provided on the self-climbing system according to the invention in the embodiment shown. As can be seen in Fig. 4, a support 62 can be concreted by the interaction with another three sections of a column formwork. Here, the provided on the self-climbing system part of a column formwork can be used as a template for the reinforcements, so that they can be introduced early.
