Description

The invention relates to a stage platform test element, with a composed of several profile elements frame, wherein the profile elements are connected to each other via connecting components, and wherein at the top of at least one profile element is formed a receiving surface for receiving a pedestal.

Such stage platform test elements have, for example, a size of 1 × 2 m. The individual platform elements are put together to form a stage platform. If necessary, this stage podium has to be of different height, meaning that no differences in height may occur between the individual podium elements, since even low edges in the stage area can give rise to accidents.

For this purpose, different stage platforms are known, which are connected to each other, for example, after installation by means of additional brackets or fittings. Some pedestals have grooves in their frame profiles, in which then corresponding connection profiles are inserted and partially additionally screwed.

From the DE 10 2005 051 966 A1 For example, a platform platform is known, wherein a receiving profile and a support profile are formed so that when joining several pedestals by suspending the support profiles of the attached pedestal in the respective receiving profiles of the adjacent pedestal a positive connection between the assembled stage platforms arises. However, this has proved to be disadvantageous in practice, since each stage platform requires its own storage on four legs.

A also known from the prior art stage platform reveals the utility model DE 84 18 502 U1 , Shown there is a height-adjustable stage platform, which consists of a plate with continuously adjustable support legs. Here, too, every single pedestal needs its own storage on four feet.

The DE 37 01 906 A1 relates to a generic stage platform test element for the construction of platforms, stands or the like, which is provided with releasable legs, wherein the pedestal block has a platform-carrying upper frame, which is held together via corner joint angle pieces.

In the prior art also stage platforms are known, which are stored on a so-called support traverse or Event Traverse. A scaffolding substructure serves, for example, to compensate for uneven ground over large spans. This is not possible with the limited foot adjustment alone. In order to place a stage pedestal on such an event traverse, it requires a special embodiment of the support frame of a stage pedestal.

In most cases, a bearing direction is always specified. The event traverse will be relocated in a specific grid. In order to achieve a fixation of the stage platforms on the traverse, the support frames of the pedestals on one side must be specially adapted. For this purpose, in the state of the art usually two opposite profile elements of a stage platform are slotted accordingly. The disadvantage, however, is that the stage platform can only be placed in one direction on the event Traverse. Furthermore, the construction is usually weakened so much that the attachment of a foot on the landing frame is no longer possible. In the edge area of the stage podium no scaffold substructures should be used. Come. In the solutions described therefore can not complete a last podium field of a stage Podium with a foot pair.

The aim of the invention is to avoid these and other disadvantages of the prior art and to provide a stage platform test element which has a composite and torsionally rigid frame of a plurality of profile elements and can be used on a scaffold carrier or a so-called event traverse. Furthermore, it should be inexpensive to produce and durable in use. Also, the pedestal should not be used exclusively on an event Traverse. An inventive pedestal should continue to be usable with normal feet. Of course, the simple installation of a stage platform is likewise an object of the invention.

The object is achieved by a stage platform test element according to claim 1. Embodiments are the subject of claims 2 to 7.

In a stage platform test element, with a composite of several profile elements frame, wherein the profile elements are connected via connecting components, and wherein at the top of at least one profile element is formed a receiving surface for receiving a pedestal plate, wherein on the underside of a profile element, a support portion is formed, wherein parallel to the support portion a oriented to the inside of the stage platform element leg is arranged, the invention provides that each support portion has a bearing surface for placing the profile element on an event Traverse and that the leg is arranged at a distance from the support portion and together with the Supporting portion forms a receiving cavity for a centering of the event Traverse, and wherein the connecting member from a substantially L-shaped angle with a first portion and a second portion is formed and that at the first portion to the second portion arranged in parallel fourth section and second section is a first portion parallel to the arranged third portion is formed, wherein the four mutually perpendicular sections forming a Steckbeinaufnahme.

Such a stage platform test element according to the invention can be optimally integrated into all event constructions based on modular scaffolding systems. The circumferentially similar profile element is interrupted at the corners of the stage platform element. This thus enables the installation of the stage platforms according to the invention in any desired direction within an event construction. In this case, the support section of the profile element is supported on an event traverse and is centered on the event traverse by the leg arranged parallel to the inside of the stage platform.

The load-bearing support portion may have on its outer side an inclined surface, which thus rounds off the support portion. This considerably facilitates the assembly of the platform elements, since a fitter will not feel any sharp edge at this "grip position". A fatigue-free work over a longer period is thus guaranteed.

Furthermore, the invention provides that the leg is arranged at a distance from the support portion. This allows for easy installation, since the stage platform test element can not jam during assembly on the scaffolding structure. Rather, between the leg and the support portion enough assembly game, which makes it easier to engage and disengage the stage platform elements on the scaffolding construction. The construction of a stage platform by means of stage platforms according to the invention is thereby not only simpler than the prior art but also faster.

Preferably, the profile element has on its inside at least one T-shaped groove. This is particularly advantageous because a particularly secure attachment of a holding means is ensured within this T-shaped groove. A recessed into the T-shaped groove holding means of the connecting member creates a good bonding effect with this. As a result, a plurality of connection components and profile elements are permanently and securely joined together to form a common frame. This support frame can thus be produced without complex welding operations and can be disassembled at any time.

Particularly preferably, a sliding block is also formed on the connecting component. This engages in the T-shaped groove of the profile element and serves as a holding means between the profile element and connecting member. This positive connection is particularly durable, but still offers the possibility of a frame dismantling.

Particularly preferably, an angle section is formed on the leg. This angle section forms a support for the connecting component. Because connecting component and profile element thereby have a further common contact surface. The torsional rigidity of the frame increases. Furthermore, an unintentional release of the profile element from the connecting member is practically excluded.

A development of the invention also provides that a cantilever is arranged at the top of the profile element. The cantilever extends over the actual extent of the profile element to the inside of the stage platform test element. As a result, on the one hand, the support surface for the pedestal is increased. Together, in effect with the angle section of the cantilever arm also provides a centering for the connecting member within the profile element. The load capacity of the frame as well as the longevity of the entire platform element is thereby significantly increased. The overall torsional rigidity of the stage platform test element is substantially improved by a skirting of the connecting elements between the angle section and the cantilever.

Preferably, the profile element has an upper cell and a lower cell. These closed cell structures ensure a high bending stiffness of the entire stage element. These cells are free of recesses and openings and thus ensure a high static strength of the profile element. The frame of the stage platform test element thus becomes more stable without at the same time increasing the weight of a pedestal element. The platform pedestal is thus easy to assemble, but still provides sufficient support reserves.

In addition, the invention provides that the connecting member is formed of a substantially L-shaped at an angle with a first portion and a second portion. The inventive design of the type mentioned above, causes the profile elements are always aligned correctly with each other. The connection component is pre-assembled. There are thus according to the invention, the orientation of the profile elements in Mounting state before. An elaborate adjustment of the profile elements can thus be omitted. By virtue of this development, a connecting component always picks up two profile elements and aligns them with one another at the same time. The assembly work of a stage platform test element according to the invention is reduced considerably. At the same time, the L-shaped angle ensures good load transfer between two adjacent profile elements.

Furthermore, according to the invention, a fourth section arranged parallel to the second section is integrally formed on the first section and a third section arranged in parallel to the first section is formed on the second section. This development of the invention makes it possible not to use the stage platform test element according to the invention exclusively on event constructions of modular scaffolding systems. The four mutually perpendicular sections at the same time form a Steckbeinaufnahme. This split leg holder allows the use of all leg systems.

So far, platform pedestals were either suitable to be stored on scaffold substructures, or to stand on four legs or feet. Thanks to the further development of the invention, a foot receptacle in the corners of the stage platform test element can be realized. Dis was not possible in the prior art, because the legs had to move through complicated designs of the profiles to the inside. In the edge area of the pedestal elements, an outward force was always created which caused a tilting moment around the respective leg. The podium elements were thus not stable. Thanks to the invention, it is now possible to relocate the legs in the outermost edge region. An outgoing force can be reduced so far that a tilting moment is negligible.

Particularly preferably, a clamping device is arranged on the connecting component. The clamping device achieves the clamping effect either via an eccentric or via set screws. Thus, a plug leg is clamped in the inventively designed cut leg recording. The stage platform test element is thus stable but nevertheless fast.

The connection component is produced in a development of the invention in the zinc die-casting process. In zinc die casting, the liquid melt of a zinc alloy is forced under high pressure and extremely quickly into a die casting mold. This process takes place depending on the required surface quality and wall thickness within milliseconds. The connecting component thus produced has a high degree of manufacturing precision, an extraordinary hardness and strength and is thus particularly durable. A equipped with such a connection component pedestal is inexpensive to manufacture and very durable.
