Description

TECHNICAL AREA

The invention relates to a lifting platform and a method for building a lifting platform.

In the field of construction so-called Schaltische are known for the encasing of building ceilings. These consist on their upper side substantially of one or more formwork panels, which form part of the formwork for a building ceiling to be created. The formwork panels are usually supported by formwork beams, which may be arranged like a lattice, for example as longitudinal and transverse beams. The formwork beams are to the bottom, i. to an existing building ceiling or the ground, supported by supports. If a building ceiling has been concreted using such shingles, it is desirable for reasons of efficient construction progress to bring these tables as quickly and easily as possible "on" the newly created building ceiling to concretes the building ceiling overlying.

STATE OF THE ART

For the transport of Schaltisch to a higher level, so-called Ausfahrbühnen known. These cantilevers of the building essentially from an existing building ceiling to the outside, so that a Schaltisch can be arranged on it, the following from a crane a higher level can be lifted. To be independent of a crane, scissor tables are also known, which can be arranged on Ausfahrbühnen or on brackets that are hung on the building. The respective switch table is placed on the lowered scissor table, the scissor table is raised, and subsequently the switch table can be set at the higher level.

In addition, elevators or hoist platforms are known which are supported on the ground and allow lifting from one floor level to a higher level. Furthermore, there are relatively heavy running consoles, which are attached to higher parts of the building. On these console solutions a lifting unit is provided. The process for repositioning or raising such a console is relatively complicated, since the lifting unit must be lifted and parked, for example, on the floor. Subsequently, the console is struck and implemented, and subsequently the lifting unit can be replaced.

From the US 3,207,263 a climbing system is known which has a comparatively small lifting platform for lifting formwork. The climbing system must be hung on a building.

The JP 06115858 A relates to a liftable platform, which can be attached to a building on several building ceilings via suitable fasteners and liftable along a rail.

The described arrangements can be referred to as lifting platforms insofar as they have a liftable platform.

PRESENTATION OF THE INVENTION

The invention has for its object to provide a lifting platform and a method of its construction, which are improved so that the lifting platform with little effort for different situations in the context of the construction progress is suitable to bring Schaltische to a higher level.

The solution of this problem is on the one hand by the subject of claim 1.

Consequently, the lifting platform according to the invention has a base, which can be set up on a floor. On the other hand, the base can be converted to a console, which can be hung on a building at a distance from the ground. The lifting platform further includes a platform that is liftable with respect to the base both in the grounded condition and in the building hinged condition. In the appropriate situation, usually at the beginning of a construction project, the lifting platform according to the invention can be placed with its base on the ground, and in this state formwork tables, which were used for concreting the ceiling of a ground floor projectile, can be raised to the ceiling of this first floor, to concretise the overlying building ceiling. The platform may be provided on the base, for example by means of one or more masts, so as to extend to further levels in the grounded condition of the base. to a second, third or higher building ceiling, counted from the ground, can be raised. In this state, the lifting platform according to the invention is thus supported on the ground.

However, the novel lifting platform has the advantage that its base is convertible to a console that can be hung on a building. As a result, the console is in other words at a distance to the ground. This offers on the one hand, the advantage that, especially in tall buildings, the masts or other components that make an elevator to higher levels, need not be extended to the extent necessary for systems whose base remains on the ground. Rather, the console can be at a certain level, away from the ground, and from there, with comparatively short masts or similar components, can enable lifting of gangways to higher levels. Furthermore, the fact that the base of the lifting platform according to the invention can be converted to a bracket attachable to a building, the area of the floor where the base was initially "released", and in this area, other work is no longer hindered.

In addition, lifting the shifter to a higher level can be done independently of a crane. The lifting of the converted to a console base of the lifting platform according to the invention can be done on the one hand by a crane. On the other hand, it is conceivable, as explained in more detail below, that the base is provided with one or more climbing profiles, by means of which the console can "climb up" on the building, as is fundamentally known for self-climbing formwork. To the console described above, which has a liftable platform and is provided with a climbing mechanism, it should be noted that this is also independent of the inventive measure, according to which the console results by retrofitting a floor-mounted base, is advantageous. Accordingly, a console having a liftable platform provided with the ability to climb on a structure in any of the above or below described embodiments, with or several of the above or below features to be considered as the subject of the application.

Preferred developments of the lifting platform according to the invention are described in the further claims.

For the base, it has proven to be advantageous if this has at least one vertical and / or horizontal profile. The vertical profile can be used advantageously to mount the console to which the base can be converted to a building. With the horizontal profile, the base can be set up in the manner of rails on the floor. However, in addition or in addition, it is conceivable that spindle feet are provided on a horizontal profile in order to set up the base in a suitable manner.

In order, as indicated above, to enable a "climbing" of the console of the lifting platform according to the invention, it is presently preferred to design at least one vertical profile as a climbing profile. This has suitable contours, for example protruding climbing cams, teeth, recesses, openings or the like, to allow engagement with suitable climbing drives. With regard to the design of the console of the lifting platform according to the invention as a "climbing console" is on June 6, 2006 entitled "Self-climbing system" filed by the Applicant patent application 10 2006 026 201.8 and its disclosure in view of all the details of the climbing system is made the subject of the application. The scaffold unit mentioned there is comparable in this respect with the console of the lifting platform according to the invention. A similar arrangement goes out of the DE 10 2005 045527 the applicant show, where the vertical profiles mentioned there correspond to the vertical profiles of the console of the lifting platform according to the invention. Furthermore, said climbing profile can be attached to cantilever beams of a building in the manner described in the last-mentioned application. Alternatively or additionally, the climbing profile can be provided with one or more guide shoes, by means of which the climbing profile can be hung and / or guided on wall shoes, as disclosed in the application mentioned above in the first place. With regard to the possibilities of lifting the protection and access device described in said application whose disclosure is also made the subject of the present application.

For the conversion of the base which can be placed on the floor to a bracket which can be suspended on a building, it is presently preferred to provide at least one profile extension which can likewise be designed as a climbing profile. Such a profile extension is preferably adjustable, which offers advantages in particular in connection with climbing profiles.

For the profile extension, it has proven to be advantageous if it can be inserted into a profile and / or hinged to a profile attachable. In particular, the articulated attachment may already be provided on the base in the grounded state. In other words, the base is placed in a condition on the ground in which at least one profile extension is already hinged thereto. Likewise, it is conceivable to attach one or more profile extensions to the base in an articulated manner and / or to insert them into profiles of the base, after the base had already been placed on the ground for some time. In any case, after the lifting of the base, the conversion to a console, inter alia, by the fact that the articulated profile extension is pivoted, for example, brought into a vertical orientation, and is rigidly connected to an existing vertical profile of the base.

Alternatively or additionally, it offers advantages if at least one plug-in profile extension is displaceable in a profile of the base. For example, it may be desirable for the console if a profile is at a level below the liftable platform. As long as the base is on the ground, in an area below the platform, i. below the base, no profile extension will be provided. According to the described preferred embodiment, however, the profile extension can first be inserted, or be provided in the inserted state at the base, and in the context of conversion of the base to a console, after lifting, are moved so that they subsequently in a level below the platform extends.

For the design of the console is currently preferred that at least one profile of the base has a suspension device with which the console to which the base has been converted to the building and / or a carrier attached thereto is suspended.

For at least one hinged attachable profile extension, it has proven to be beneficial to provide them with a preferably adjustable support device. For example, in an area below the liftable Platform made an oblique support to a vertical profile. Such, serving as a support profile extension may initially be provided on the base articulated and folded in the context of raising the base and / or the conversion thereof to a console in the correct orientation and connected to at least one profile.

As mentioned, it is basically conceivable to provide the platform in a suitable manner such that it can only be raised to the next level above it. However, it is currently preferred to design the platform so that multiple levels, i. E. several storey heights can be bridged. For this purpose, it is currently preferred to provide the lifting platform with at least one lifting masts, which can be extended in an advantageous manner.

For a stable connection between the base or the console of the lifting platform according to the invention and the masts described, it has proven to be beneficial to connect the masts with at least one profile of the base / console. This is advantageous in that additional anchors in the upper area of the masts are unnecessary.

In order to make the lifting platform according to the invention suitable for as many applications as possible, it is presently preferred to make the platform widenable. This is preferably done by individual modules that can be added to the site. Alternatively, it may be convenient to make the platform telescopic.

On the other hand, the invention provides a method for constructing a lifting platform in which, with few individual parts and in an efficient manner, a possibility can be created of bringing shift tables to higher levels.

According to the method of the invention, a lifting platform having a base and a platform is constructed by first placing the base on the ground such that the platform is liftable with respect to the base. In this state, it is thus possible to bring shingles from the level of the floor to the level of higher floors to concretes ceilings there. However, the base will later be raised and converted into a console that can be hung on a building. This console can be subsequently hung on the building in a state that the platform is in turn liftable. As a result, it is also possible to raise shift tables to higher levels, even from higher levels. In addition, the floor is not permanently occupied by the established base, as is the case for known elevator or lifting mast systems. Finally, those components, such as lifting masts, which allow lifting to higher levels, can be kept comparatively short during the entire construction step, as the console, as mentioned, can be suspended at a certain level on the building, and from there the possibility of Lifting of Schaltischen can be guaranteed to higher levels.

The preferred developments of the method according to the invention essentially correspond to the preferred developments of the lifting platform created thereby.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

As in Fig. 1 can be seen, the base 12 of the lifting platform 10 according to the invention in the embodiment shown at least two vertical 22 and at least two horizontal profiles 24, of which in Fig. 1 only the right profile can be seen, while the respective left or rear profile covered by the platform 20 is. It will be understood that further profiles may be present below and behind the platform and that the profiles are interconnected to form a rigid base 12 which, as in FIG Fig. 1 shown, can be set up on a floor 14. In the embodiment shown, the base is further provided, for example on its outer sides, with lifting masts 30.1, 30.2, which enable lifting of the platform 20 to a higher level via suitable drives. The masts 30 may be extendible. In particular, they can be so extensible that lifting the platform 20 to the level of an overlying building ceiling 18 (see. Fig. 2 ) or to an even higher level is possible. For stability of the respective mast 30 is firmly connected by a respective strut 32 with a profile 22 of the base.

The lifting platform according to the invention is in Fig. 1 in a situation where she is already prepared for conversion to a console. This manifests itself in that in the two vertical profiles 22 each have a profile extension 26 is inserted from the top, which is displaceable in the profile 22, as soon as the lifting platform is raised. On the horizontal profiles 24 each have a second profile extension 28 is articulated by means of a hinge 34. The base can be placed with the already provided thereon profile extensions 26, 28 on the floor. Alternatively, it can be placed on the ground without said profile extensions, and these can be subsequently attached. As part of the conversion to a console, the lifting platform is raised in total, ie including the base 12, so that the profile extensions 26 are displaced in the profiles 22, but remain substantially stationary, while the lifting platform is raised. This lifting further allows the profile extensions 28 to be pivoted into the area below the base 12 and subsequently secured to the profile extensions 26 now below the base 12 for support. As a result, when viewed from the side, substantially the shape of a right triangle consisting of the horizontal profile 24, the profile extension 26 and the downwardly folded profile extension 28 is formed. The right angle is formed between the horizontal profiles 24 and the profile extension 26. After this conversion, the aforementioned profiles and profile extensions form a console that can be hung on a building.

This condition is in Fig. 2 shown. Compared with in Fig. 1 situation shown, the base 12 was raised, so that they, in Fig. 2 by way of example, located in the area of a lower building ceiling 18.2 of two building ceilings 18.1, 18.2. In connection with the lifting, the profile extensions 26 have been pushed downwards by the profiles 22, so that a support of the base 12 by means of the further profile extensions 28 folded downwards in the meantime can be made on the profile extensions 26 pushed downwards. In the manner described, the base 12 has thus been converted to a console, which is suspended on a building, in the case shown on the lower ceiling 18.2 at a distance from the ground. In the embodiment shown, a safety gate 36 is provided on the building ceilings 18.1, 18.2 to the lifting platform 10 out. When the safety gate 36 is open, shunting tables, as in FIG Fig. 2 shown by way of example in the form of the switching table 38, are placed on the liftable platform 20 of the lifting platform 10. After lifting the Platform 20 by means of the masts 30 and suitable drives the Schaltisch 38 can be discharged to the higher building ceiling 18.1 and used there for shuttering the next building ceiling. To bring the Schaltische to even higher levels, the masts 30 can be further extended. In this context, they may be attached separately from the base 12 to one or more building decks 18. Further, the lifting platform 10 can be brought to higher levels including the hanging on the building serving console 16 by the console is detached from the building ceiling 18.2, and brought for example by means of a crane to a higher level and hooked there.

Alternatively, as in Fig. 3 and 4 shown lifting the console done by a climbing system. The embodiment of Fig. 3 corresponds to much of the embodiment described above with the exception that the vertical profiles 22, of which in the side view of Fig. 3 only one is visible, are designed as climbing profiles, which are provided in the example shown with the climbing climbing cam 40. It is understood that instead of the climbing cam 40 also protruding teeth, recesses, a hole profile, or other suitable contour can be used. In addition, in connection with the details of a climbing system, reference should be made to the above-mentioned applications of the Applicant.

Another difference between the embodiment of the Figures 3 and 4 and those of FIGS. 1 and 2 is that the vertical profile 22 by a pivotable profile extension 42 is extended, which is also designed as a climbing profile. In an area of the Horizontal profile 24, which is spaced from the building (see building ceilings 18), further profile extensions 28 are provided so that the in Fig. 3 shown base 12 can be converted to a console 16, the in Fig. 4 is shown. to Fig. 3 it should be mentioned that here the parked on the floor 14 state of the base 12 is shown. For this purpose, a plurality of feet 44 may be provided on the base 12, in particular on the horizontal profiles 24, which create a space below the base 12 to the bottom 14 in which the profile extensions 42 are receivable.

The conversion to the in Fig. 4 shown bracket 16 is carried out in this embodiment, characterized in that the base 12 is raised, so that the profile extensions 28 can be folded into the area below the vertical profiles 22, and are subsequently bolted to the hinge point 46, so that they are rigidly interconnected. As in the embodiment of FIGS. 1 and 2 a support of the Horizoritalprofile 24 by the obliquely provided in the final state profile extensions 28, which are preferably adjustable in this case. By means of the climbing cam 40, the climbing profiles 22, 28 can be suspended in guide or wall shoes, which are attached to the building ceilings 18. By suitable drives (not shown), the entire console can be raised, as described in detail in the referenced applications. Alternatively, a lifting by means of a crane is also possible for this embodiment. In particular, a guidance of the console by the engagement of the climbing profiles 22, 28, which may be embodied for example as I-profiles, with the wall or guide shoes, also possible when lifting by means of a crane.
