Description

Shuttering element with identification means

Dxe invention relates to a formwork element with a formwork skin and with at least one on one edge or close to an edge of the formwork facing away from this on the concrete m use position facing away from the existing metal edge web or outer frame or the formwork supporting the support, wherein on the formwork element at least one transponder is arranged as identification means.

An example of a circuit element with an edge web or outer frame projecting on the edge of the formwork skin is described in EP 0 573 450 B1.

Another example is disclosed in EP 0 729 536 B1.

A formwork element with supports supporting the formwork facing is shown in DE 24 26 708 C3, wherein the formwork elements may or may be curved, but comparable formwork elements in the form of rigid formwork panels with corresponding, for example, parallel supports are also known.

Formwork and thus the formwork elements are leased to a large extent or claimed by leases from customers temporarily, that is, there is in such formwork and formwork elements, the problem that the shuttering elements used must be withdrawn after a certain time again.

It is often not possible to determine exactly whether the temporary User really returns those formwork elements he had rented or leased and there is a risk that the user retains still in good condition formwork elements or formwork parts and returns in his possession located worse or more worn formwork or formwork parts.

It is therefore desirable to characterize formwork elements or at least more valuable formwork panels so that they can be identified and recognized when taking back.

In addition to color markers transponders have become known.

From DE 100 55 060 A1 it is known to provide a through hole for accommodating a transponder in the frame sheet of a formwork panel, in which a special holder for the transponder can be accommodated, which has to be regarded as expensive and also prone to breakdown, especially since Holder could be removed if necessary unauthorized. In addition, the through holes for this special holder is to be regarded as weakening of the edge web or frame at the same time.

It is therefore an object to provide a formwork element of the type mentioned, the edge webs or outer frame or support may be made of metal without a special holder for the transponder or is required and must be installed.

To achieve this object, it is provided in a shuttering element of the type defined at the outset that on the edge web or outer frame or support on its from the formwork facing off. facing, in use position a neighboring formwork element or building end facing surface is provided at least one recess which is larger than a flat transponder, and that the transponder is arranged and held in this recess of the boundary.

Instead of a complex holder is thus introduced into the corresponding metallic part of the formwork element, which is well accessible especially when stacking formwork elements stacked from the outside, a depression, m which m position of use of the transponder is housed isolated, so that its electromagnetic signals from the transponder can be dispensed or picked up well, without being disturbed or "swallowed" by the surrounding metal of the edge web, frame or carrier, since a special holder is avoided, no special mounting of such a holder is required Advantage that their attachment means virtually no extra effort, the edge bar, frame or carrier but less or not weakened.

It is particularly expedient and simple in this case if the transponder m the recess is held or fixed by a plastic and / or adhesive.

The transponder can therefore be easily introduced together with the recess or together or after or before the attachment of a corresponding plastic or adhesive mass m or set or then fixed with the mentioned mass, whereby it can be protected at the same time against mechanical or pollution originating damage.

It is expedient, if the recess on the in Rieh closed to the middle of the formwork panel side of the edge web or frame or carrier or - optionally subsequently - is closed. Thus, the open side of this recess for a corresponding sensor or scanner or detector from the outside is easily accessible.

A particularly expedient embodiment can provide that the formwork element is a formwork panel with a metallic outer frame, which consists of approximately perpendicular to the formwork facing edge webs from Flachmateπal or from a profile, the cross-section of the edge web of the formwork facing away up to a free or spaced edge is, with the edge webs m use position edge webs of neighboring formwork panels rest directly or indirectly and attack connecting means for mutually securing the adjacent or adjacent edge webs, and that the transponder receiving recess located on the m direction away from the center of the formwork panel outside of or the edge web or the outer frame is formed against this outside in the direction of the center of the form panel hm recessed.

The marginal edge web or outer frame can therefore at the surface, which faces an eventual neighbor panel, have the corresponding recess which opens to this outside, that is, the transponder can be inserted from this outside into the recess and then be well detected from this outside.

An advantageous embodiment may consist in that the / the edge webs are formed from flat material and the depression is impressed. Em such embossing process is easy feasible and ergxbt an effective way to form the open to the outside hm recess for the transponder, without affecting the stability of the edge web or frame part.

But it is also possible that the edge web about as EP 0 729 536 B1 a profile or extruded profile or a hollow profile, and a hollow profile made of steel, and the recess worked by cutting or non-cutting removal of material, in particular milled. In addition to a cutting process, erosion of the corresponding depression would also be conceivable.

It may be advantageous if the edge web is an aluminum extruded profile with cavities running in its longitudinal direction-in order to save weight with good rigidity-and if the depression is arranged at a location at which the extruded profile has a solid cross-section-ie no cavity - Has.

The transponder can be recessed in the position of use m the depression so far that it is covered or covered on its side facing the outside with the plastic and / or adhesive, and this cover of the transponder can preferably with the outer surface of the edge web or outer frame or support finish flush. It results in such a flush conclusion then a surface of the edge web or carrier on which the position of the transponder is not readily apparent to unauthorized persons and contamination of the transponder are largely avoided. Nevertheless, it is also due to the cover against even more aggressive materials such as concrete milk or the like dirt and also against mechanical loading protected.

It is particularly favorable when the transponder is embedded in the recess in the plastic and / or adhesive mass. It can therefore first this plastic and adhesive filled into the depression and then pressed the transponder in the still compliant mass and thereby embedded, or it can first inserted the transponder and then filled the mass m the recess already containing the transponder and this be covered by the mass at least outwardly.

It is particularly advantageous if the plastic and / or adhesive is a two-component adhesive based on epoxy resin. On the one hand, after setting or curing, this results in a stable conclusion that protects the transponder and, on the other hand, permits long-term secure fastening of the transponder in its recess.

So that the position of the transponder does not have to be taken into consideration when stacking such formwork elements and yet the identification of the respective formwork panel is possible without difficulty, it is expedient if the formwork element is a rectangular formwork panel which is perpendicular or parallel to at least two transponders in recesses m spaced apart from one another Having arranged to each other edge webs or carriers. Parallel edge webs or carriers close to the edge are each located at mutually spaced edges, so that the formwork panels, even when stored in a position rotated by 180 degrees, again turn to the user an edge web or carrier m which then one of the transponder is housed. Of course, all transponders of a formwork panel can have the same identification features. It may be beneficial if in at least two edge webs or carriers each near a corner of the rectangular

Shuttering element per a recess for a transponder is provided. By means of such an arrangement near a corner, the transponder may possibly also be well detected if the edge web containing it runs away from the user, because the transponder is still close to it

User at the corresponding corner of the formwork element.

The use of the transponder or transponders may be even easier if the two depressions on the formwork element lie approximately in the center and / or on a line running through the middle of the formwork element. Even at 180 degrees rotated position is then in each case one of the transponder m a portion of the stack, which can be detected well.

It is advantageous in particular for the manufacturing costs of the formwork panels if the transponder is a passive transponder, although the use of an active transponder would also be conceivable in an analogous manner.

Especially when combining one or more of the above-described features and measures results in a formwork element with metallic edge webs or carriers on which transponder well detectable and yet protected can be accommodated without special holders are required. Nevertheless, the corresponding edge webs, support or outer frame may be made of metal, since the transponders are housed in the corresponding embossed or milled depressions shielded and protected, but without this edge webs, frame parts or carrier weakening Through holes and matching special holder for the transponder required.

Hereinafter, embodiments of the invention are described in more detail with reference to the drawing. It shows m partly schematized representation:

Fig. 11 is a side view of the large-scale panel according to Fig.10 overlooking a near-edge support.

In the following description, parts which correspond to one another in terms of their function receive matching reference numbers even with different configurations.

A generally designated 1 formwork element may be a formwork panel of different construction, as can be seen for example with reference to Figures 1 to 5, 6 and I ₁ 8 and 9 or 10 and 11 recognizes. Common to these differently shaped formwork elements 1, that they have a formwork skin 2, which is also indicated in Figures 4, 6 and 8 by broken lines. This makes it clear that at or near the edge of the respective formwork skin 2 projecting therefrom on the side facing away from the concrete in the position of use metal edge webs 3, which can also form an outer frame in the embodiment of Figures 1 to 3.

In the embodiment according to FIGS. 10 and 11, the formwork skin 2 is supported by vertical use parallel support 4 m, wherein m this case near the edge of the formwork 2 such support 4 extend, which can be additionally connected by a harness 5. Depending on the design of the harness 5, this rigid or optionally analog DE 24 26 708 C3 is also variable in length to bend the formwork skin.

All exemplary embodiments have in common that at least one transponder 6 is arranged on the respective shuttering element 1 as an identification means.

It can be seen m all embodiments and particularly well in Figures 4 to 9, that at the respective edge web 3 or support 4 facing away from the formwork facing 2, in use position a neighboring formwork element 1 or a building part or a corner facing surface at least a depression 7 is provided, which is larger than a flat transponder 6, and that the transponder 6 is arranged and held in this depression 7 by its boundary.

Above all m Fig.4, 6 and 8 can be seen clearly that the Recess 7 surrounds the transponder both on its underside and on its circumference and includes and only leaves its top free, which can be detected well in this way.

In this case, the transponder 6 in the recess 7 by a plastic and / or adhesive 8, hereinafter also referred to as "mass 8", held and fastened, which is easily recognizable, especially when jointly viewing Figures 4 and 5. Above all In the exemplary embodiment according to FIG. 7, the mass 8 also engages over the outer edges of the recess 7 in order to achieve a good mounting, as is the case with the embodiment according to FIGS.

In all embodiments, it is provided that the depression 7 is closed on the side of the edge web 3 or frame or carrier 4 located in the direction of the center of the formwork element or the formwork element 1, optionally subsequently also closed, that is to say the edge web 3 or support 4 is not weakened by a through hole or through hole.

The exemplary embodiments according to FIGS. 1 to 7 disclose a formwork element 1 m in form of a formwork panel with a metallic outer frame which consists of edge webs 3 of flat material or optionally of a profile projecting approximately at right angles to formwork skin 2, the cross section of the respective edge web 3 of FIG the formlining 2 is directed away to a free edge 3a, wherein at the edge webs 3 m use position edge webs of neighboring formwork panels rest directly or indirectly and Verbmdungsmittel for mutual attachment of such contiguous edge webs can attack continuing formwork panels. The the Transponder 6 receiving recess 7 is formed on the outside in the direction of the center of the formwork panel 1 away 3 b of the respective edge web 3 with respect to this outer side 3 b m direction towards the center of the formwork panel towards springing back. The same applies to an edge web 3 designed as an extruded profile according to FIGS. 8 and 9.

In the embodiments according to Figures 1 to 7, the edge webs 3 are formed from flat material and the recess 7 is embossed, that is generated by a cold deformation. The strength of the edge web is also correspondingly high in the region of this depression 7.

In the embodiment according to Figures 8 and 9, the edge web 3, as already mentioned, an extruded profile and the recess 7 is machined by a machined or non-cutting removal of material, for example, milled. In this case, this edge web 3 may be an aluminum extruded profile with extending in its longitudinal direction cavities 3c and the recess 7 may be disposed at a location at which this extruded profile has a solid cross-section, so that again a weakening of this edge web 3 is largely avoided by the recess 7.

However, the transponder 6 can also be arranged in a depression 7 of at least one of the boundary webs of a hollow profiled web, for example a closed hollow profile or rectangular profiles, as far as this web has sufficient strength. For example, the flat profiles shown in FIG. 4 or 6 could also each be a particular outer boundary of such a hollow profile, which could be arranged or also circulated on the edge of a corresponding formwork element 1. The transponder 6 is in all embodiments in the position of use far enough sunk into the recess 7, that on its outside of the 3b side facing the plastic and / or adhesive 8 is covered or covered and this cover of the transponder is shown in FIG , 6 and 8 flush with this outer surface of the outer side 3b of the edge web 3 or carrier 4, so that the transponder 6 is not only well protected, but also hidden, so that unwanted manipulations and mechanical damage are largely excluded.

In particular, the already mentioned representations in FIGS. 4, 6 and 8 illustrate that the transponder 6 is embedded in the recess 7 in the mass 8, that is, it is practically enclosed by it on all sides. In this case, this mass 8 may be a two-component adhesive based on epoxy resin, which gives a good support of the transponder 6 in the recess 7 and this also protects well against damage of all kinds.

In Figures 1, 3 and 10 is still indicated that the formwork element 1, which is each a rectangular formwork panel, at least two transponders 6 m spaced recesses 7 m rectangular or parallel to each other arranged edge webs 3 or supports 4, so that at Stacking these formwork panels does not have to be paid attention to the location of the transponder 6, but always one of the transponder 6 m is arranged a convenient location for detecting.

In the exemplary embodiments, at least one depression 7 for a transponder 6 is provided in each case in at least two edge webs 3 or supports 4 each near a corner of the rectangular formwork element 1. As cheap or still It is more favorable, however, if the two recesses 7 on the formwork element 1 approximately centrally of an edge web 3 or support 4 and / or on a running through the middle of the formwork element 1, imaginary line.

In this case, a passive transponder 6 is provided in the embodiment, so that it does not increase the cost of the formwork element 1 appreciably.

The formwork element 1 with a formlining 2 and at least one arranged on an edge or near an edge of the formwork 2, made of metal edge web 3 or outer frame or the formwork skin 2 supporting carrier 4 has as Identiflzierungsmittel on a transponder 6, the m a recess 7 of a Edge web 3 or outer frame or support 4 is remote from the formwork facing 2, in the use position a neighboring formwork element facing surface is arranged. This recess 7 encloses the transponder 6 laterally and on a surface, so that only one surface is accessible to the outside for a detector, because the recess 7 on the located in the direction of the center of the formwork panel or formwork element 1 side of the edge web 3 or frame or carrier 4 is closed. The holder of the transponder 6 m of the recess 7 by means of a plastic and / or adhesive. 8
