Description

Technical field

The invention relates to a stage element and a stage system with several stage elements that are in the field of Construction is usable.

When building structures are scaffolding that made numerous stage elements can be built for all kinds of work required. For example, must the reinforcements are attached from scaffolding. Further are usually the ones required for concreting Formwork elements set up from scaffolding. Even during of concreting workers are on scaffolding, to those containers or devices from which the Concrete flows between the formwork to handle. Also Work on the facade is carried out from scaffolding. Finally, climbing formwork systems are common scaffolding mounted on climbing brackets to get from these scaffolding from all of the above activities in With regard to the new above the climbing console to be able to carry out the concrete section of the building.

State of the art

A wide variety of scaffolds are known in the prior art adapted to each of the above activities are. For example, there are facade scaffolds where vertical beams in a certain grid like this be set up between four in the Top view of a rectangle forming a stage covering can be hung up. It is from EP 0 195 806 B1 especially known to provide an entire scaffolding module, at which the stage coverings are hinged to the beams, so that those arranged on one side of the work surfaces Beams on the beams arranged on the other side can be folded so that the scaffolding module as a whole can be collapsed comparatively small.

In WO 90/14479 a scaffold is also disclosed all four corners of rectangular work platforms Has carrier, the work platforms either foldable or foldable attached to the straps, which are in the installed state on the back of the building.

Such scaffolds are for certain work on the structure quite usable. In particular for reinforcement such scaffolds are worked out, with those Beams that are arranged towards the building interfere can. However, before the formwork elements are used, it is necessary that described in the above Dismantle scaffolding designed in this way. Setting up the Formwork elements is not possible if the scaffolding stay set up because the formwork elements in exactly that Area to be handled by the scaffolding, and here in particular those arranged towards the building Carriers is taken.

For this reason, it doesn't offer an alternative, To build facade scaffolding on work platforms, which on the already built part of the building are anchored. Next the above disadvantages there is a problem that the facade scaffolding on the work platform is tensile would have to be anchored, what for the known stages there are no connections. After all, they are Facade scaffolds are therefore not suitable for this purpose, because material is often used to carry out subsequent work what has to be put on the stages Facade scaffolding is only possible on the top stage.

These disadvantages are also the subject of DE 197 18 650 A1 has not been rectified, in the case of additional parts a possibility is created, common facade scaffolding frames to be attachable to a building wall To expand the console frame. This will only be a replacement created for separate console frames.

In the field of climbing formwork, it is known Attach working platforms to formwork elements, which means that Possibility is created, for example during the To work on these platforms. Since the Working platforms fixed above the formwork elements are, however, they are useless for reinforcement, so that own auxiliary scaffolds are required for this. Hence it also applies to these solutions that they are only for certain activities are suitable, and further scaffolding for the other activities are required.

Finally, DE 89 09 026 U1 is a folding platform known that a frame and a foldable on it attached stage covering. By means of the frame the folding platform can be attached to the building anchors. With this stage can therefore never be a section of a building that is on the same level as the stage. Furthermore, any work required on the building due to the frame attached directly to the building with special needs.

Presentation of the invention

The invention has for its object a stage element and a stage system with several stage elements create that can be used flexibly and that is for the Implementation of numerous different activities in the Suitable for the construction of a building.

This problem is solved by the features of Claim 1.

Detailed description of preferred embodiments of the invention

In Fig. 1 is in an unfolded state and one Attachment state appropriate orientation from the side Stage element 14 according to the invention in a first Embodiment shown. This points as part of the Stage element 14 does not have a support, but rather an im Attachment condition on the side facing away from the building arranged support element 18 with which the stage element can be attached to a carrier, as will be described below 3 is explained in more detail. In the shown Case has the stage element 14 on both (from the front or Back from the considered) side marginal areas shown support member 18 (see. Fig. 3).

From the support element 18 extends in the attached Cantilevered state in the direction of (not shown) Building a stage covering 22, which is towards the support element is supported by a strut 36. According to the invention Stage covering 22 is designed to be foldable, which is shown in the Embodiment is realized in two forms. To the one is located at the transition between stage covering 22 and carrying element 18, a first folding hinge 38, by means of the stage surface 22 of which is shown in FIG. folded position can be brought. As below is explained in more detail, this function in the Use of the stage element 14 together with other stage elements arranged above can be used to Stage covering 22 of the top stage element 14 completely fold back to the material from above underneath stage coverings or the reinforcement bring in.

As in the course of the extension of the stage covering 22 in The stage covering shows the direction of the building 22 of the embodiment shown in Fig. 1 another Folding hinge 40 between the foremost area 42 and a rear area 44 of the stage covering 22. Means of the hinge 40, the front area 42 can be entirely or partially folded back towards the rear area 44 so that in the area where the foremost Area 42 is in the extended state without mutual interference a formwork element can be arranged can. This is from a stage system that through several of the stage elements 14 shown are formed, both the reinforcement for which the fully unfolded Stage covering 22 is used as well as the following Setting up the formwork elements possible, with the foremost region 42 at least slightly upwards or is completely folded back onto the rear area 44. In Fig. 1 it can finally be seen that from the Support element 18 from upwards a protective device 24, usually in the form of a grid, extends around the To secure the rear of the building.

As can be seen from Fig. 2, the inventive Stage element 14 advantageously in a small space fold. For this purpose, the stage covering 22 is a total of the hinge 38 upwards, in the direction of the guardrail 24 folded, the strut 36 being released from the support element and is folded in the same orientation. In the in 2, collapsed state can be several stage elements on top of each other with little space requirement store by placing it in a opposite of the representation brought by Fig. 2 rotated by 90 °, flat orientation become.

FIG. 3 shows how three of those in FIGS. 1 and 2 shown stage elements 14 to a stage system 10th be combined. For this purpose, the three stage elements 14 one above the other by means of their respective support elements 18 two columnar supports 20 attached and by bolts or fastened with a quick connector. The carriers 20 point a grid of openings or, for example, projections so that the stage elements are each at a suitable height can be assembled. As shown in Fig. 3 in combination 1 results in the collar Stage elements 22 each forward, that is, according to the 3 from the plane of the drawing, from, so that there are none in the area facing the building additional support elements or supports are located, and in this Area can be worked freely. Of course you can the stage system 10 shown in Fig. 3 with ease additional sections arranged laterally or above of the stage system can be combined to make a total multi-storey, large-scale facade scaffolding or a scaffold to train a climbing system. In particular, the shown carrier 20 with further, arranged above Carriers for example via a flange or Plug connection to be coupled.

This applies in the same way to that in FIG Side view shown second embodiment of the Stage element 12 according to the invention. This corresponds with regard to the two foldable in the case shown Training of the stage covering 22 and its support by a strut 36 of that shown in Figs. 1 and 2 Embodiment. Instead of the support element 18 of the first Embodiment is the stage covering 22 with a Carrier 16 connected. In the carrier 16, of which as in the 3 on both side edges one is provided in each case (see FIG. 6) essentially vertically aligned in the mounted state Strive through suitable fasteners 46 the carriers 16 designed in the same way Stage elements are attachable, so that one multi-storey scaffolding, each with freely cantilevered Stage coverings 22 results. Even with the one shown Embodiment of the second embodiment is in the rear area, a protective device 24 is attached.

5, the second is also Embodiment of the stage element 12 according to the invention by means of the hinge 38 over which the stage covering 22 is mounted in a foldable manner on the carrier 16 in one flat shape collapsible. This can also a plurality of stage elements 12 of the second embodiment small space can be stacked flat on top of each other. This results in comparison to the first described above Embodiment the further advantage that no additional Carrier must be stored, since this in the form of the carrier 16th are provided as part of the stage element 12.

6 is in accordance with the representation of FIG. 3 Example of a stage system 10 shown that consists of three stacked stage elements 12 of the second Embodiment consists. As can be seen from Fig. 6, the Carrier 16 is provided on both side edges. It is mentions that the beams 16 of the second embodiment in FIG their lower area can be designed so that they not only with the beams of 16 other stage elements are connectable, but also on level ground can be set up and on the console of a climbing formwork system are attachable, as will be explained in more detail below. Of course, this applies in the same way to the at of the first embodiment provided supports 20 on which preferably several stage elements 14 can be attached. It is still mentioned that the carrier 16 currently has a height of 2 m is preferred, so that accordingly a Stage system can be set up, the stage coverings 22nd are at a distance of 2 m from each other in height.

In Fig. 7 is a side view of the use of Stage system 10 according to the invention shown in the reinforcement. In the situation shown, the inner formwork 48 is already in place set up and supported against the floor 30. For the Stage system 10 can be seen that it is also on the flat floor 30 is set up. It should be mentioned that in the 7 to 9 a stage system consisting of several Stage elements of the second embodiment is shown, and that of course also consists of a stage system Stage elements of the first embodiment can be used.

As can be seen in FIG. 7, the top stage covering is 22 folded back, what for attaching the reinforcements 50 was beneficial. In the situation shown in Fig. 7 are now from the two lower stage coverings 22 the reinforcement work was carried out. It is advantageous here unfold the stage coverings 22 completely so that the workers as close as possible to the reinforcement 50 can get close. The freely cantilevered training of the Stage coverings 22 have the advantage that in the area of Reinforcement work no disturbing girders or supports available.

8 shows the advantageous usability of the novel stage system 10 also for those after the reinforcement necessary work. For one thing, it's like the two lower stage coverings can be seen, the respective front Area 42 advantageously partially folded back that space for a formwork element 34 is created. This is also appropriate Fastening and adjustment devices 52 on the respective Carriers 16 of the stage elements connected. So how 8 shows the stage system 10 according to the invention also for setting up and fixing the formwork elements 34 usable. In addition, as in the upper area of the Fig. 8 can be seen, the concreting work of the stage system 10 according to the invention can be carried out from without being displaced or by another stage system or scaffolding needs to be replaced. The cantilever Training of stage coverings 22 offers in this context the advantage that the concreting work is not carried out by beams or supports are disturbed. This advantage is particularly compared to the conventional facade scaffolding that can replace the stage system according to the invention. The For completeness, it should be noted that in a similar way, as shown in Fig. 8, the concreting of Ceiling is possible by placing inside the building instead of the inner formwork 48 shown in FIGS. 7 and 8 Slab formwork system is set up on the following also from the top stage covering in FIG. 8 is concreted. Furthermore, this is when concreting on the Personnel located on the ceiling through the top stage covering protected from a crash.

In Fig. 9 is finally shown how that Stage system 10 according to the invention in an advantageous manner a climbing formwork system that can be combined Has console 32 on which the stage formwork system 10 can be mounted with its lowest support 16. To do this the stage system 10 usually largely assembled state to that by means of Climbing devices attached to the outside of the structure Consoles 32 raised. Below is the stage system 10 as Part of the climbing formwork system in turn for all of the necessary work can be used. First of all, in the Fig. 7 corresponding situation from the complete unfolded stage coverings 22 performed from the reinforcement become. As can be seen in FIG partially folded stage coverings 22 the Formwork elements 34 of the outer formwork introduced and to the Carriers 16 of the stage system 10 are fixed. Finally can in particular from the top stage covering 10 Concreting can be carried out. If the outer formwork too has to be removed at any time, so it offers itself turn on, the stage coverings 22 at least partially fold back so that there is enough space for handling the Formwork elements 34 is available. It was still mentions that the full scaffold that is created by the stage system 10 according to the invention is formed together with the formwork elements 34 attached to it, the console 32 and the suspended platform 54 below using a Crane can be implemented if this instead of one Climbing systems are used.

Furthermore, the stage covering 22 can each have an integrated one Have access, so that in a scaffold that through numerous stage elements arranged side by side and one above the other 12 or 14 is formed by combination with appropriate ladder elements a complete step can guarantee.

10 is an alternative in a side view Embodiment of the stage system 10 according to the invention shown. This embodiment agrees with the embodiment 4 to 6 to the extent that the individual Stage element 12 has a support 16 on which a free cantilevered stage covering 22 is attached foldable. The 10 differs from 4 to 6 in that the stage surface 22 in the region of the upper end of the individual carrier 16 of the Stage element 12 is attached. This results in the Advantage that the massive support 16 of the top Stage element (see FIG. 6), which in itself is static Reasons no longer required to be saved can. As shown in Fig. 10, the top one ends Stage element 12 in the area of the topmost attachment point Stage covering 22, and above the level extends in In contrast to the embodiment from FIG. 6, no carrier 16 more. To meet the security requirements is in the upper end of the two arranged parallel to each other top carrier 16 is only a comparatively light Plug railing 24 inserted as a protective device.

As can be seen from the lower area of FIG. 10, extends in this embodiment of the invention Stage system 10, the respective protective device 24, that is Railing of the individual stage element 14 from the lower one End of the carrier 16 to the required height. The Stage covering for the lowest level (apart from the Suspended platforms 54) arranged underneath will be supported by the Stage surface of the console 32 formed, in which the Dashed indicated step is formed. Regarding the attachment of the carrier 16 is still noted that this, as can also be seen from the figure is, in the case shown on the console 32 or at other applications on a suitable shelf support are additionally supported by support struts 56. Hereby the individual carriers 16 can be dimensioned somewhat more easily become what increases their economy.

Another difference between the embodiment according to Fig. 10 and the embodiment shown in Figs. 4 to 6 is that the stage surface 22 is down overall can be folded down. As can be seen from FIGS. 2 and 5, is at the embodiments described so far, an upward folding intended. Since the stage surface 22 at 10 in the region of the upper Carrier end of the individual carrier 16 is a Folding down is advantageous, as this makes the Dimensions of each prefabricated and folded stage element 12 within appropriate limits can be held. Specifically, the stage covering 22nd folded down for transportation and storage, that it rests on the protective device 24. In Agreement with those described above Embodiment is the foremost portion 42 of the individual stage covering 22 also in the embodiment of Fig. 10 foldable upwards.

With regard to the console 32, it should also be mentioned that the Area on the rear of the building between the support struts 56 can advantageously be used to material put down and to the stage covering from the back of the building feed. For this purpose, for example, the on furthest edge of the console 32 from the building as well as to the building in the area of the respective Support struts 56 extending a railing, and the railing 24 shown in FIG. 10 at the lowest Stage element 12 is eliminated. Similarly, it is of course also on all other stage elements 12 of the stage system shown possible on the back of the building own consoles for storing and feeding material to attach, but this is not shown in the figures.

Finally, it should be mentioned that the one at the bottom of the Console 32 attached suspended platforms 54 made of prefabricated and easy to assemble stage elements exist Stage covering is also foldable attached. Finally, in the area of the suspended platforms in advantageously bridging girders, for example for Bridging building openings, used as they are are known for conventional folding platforms.
