The invention relates to a prefabricated Schaltisch, such as in the field of construction, in particular for the Formwork of ceilings is used.

When concreting a floor slab of a concrete structure is a substantially horizontally arranged Formwork skin created whose edges by so-called Stirnabschalungen be limited. The formwork can be through a variety of formwork panels are formed, the are placed on so-called cross members, which in turn are placed perpendicular to so-called Jochträger. The yoke beams are usually through in several places so-called ceiling supports supported to the ground.

State of the art

From EP 0 945 564 A1 a Deckenschaltisch is known, the insofar prefabricated, as the formwork in the form of several formwork panels attached to the cross members, and these are attached to the yoke beams. At the yoke carriers Furthermore, connecting elements are provided with the Connecting elements can cooperate on the Top of ceiling supports are provided. By the prefabricated unit consisting of the formwork panels, the transverse and the yoke beams can be modular elements are provided, which only with the supports must be provided to together with other such Elements to form a complete slab formwork. The prefabricated elements can be used in particular in time and cost-effective way between individual floors be implemented to successively cover the ceilings Concrete multi-storey building.

From DE 100 56 831 C1 is a similar Ceiling scarf device, in which at least the Yoke beams are made of steel. The supports are on so-called supporting frames connected, each between be attached to two adjacent yoke beams.

Presentation of the invention

The object of the invention is a Deckenschaltisch to create that in an efficient manner its possible uses is improved.

The solution of this problem is achieved by the in claim 1 Schaltisch described.

Accordingly, the inventive, prefabricated Schaltisch a formwork on, on several cross members is attached. The formwork skin can, for example, consist of several Formwork panels exist. For the cross member is preferred that these are made of wood. In contrast, are at least two yoke beams made of steel, on which the Cross members are attached. At the yoke carriers are the required supports fastened by connecting heads, which serve the attachment of the supports, in each case one single Jochträger are attachable. This will be done realized that at least two of the existing yoke beams along essentially its entire length in regular Distances are provided with holes. At these holes the said connection heads are attached. This can for example, by means of inserted and secured Bolt be made. With regard to the attachment of Supports on the connecting heads is to mention that these can be done via a spline connection. This will be a or more wedges wrapped in such a way that they support by means of a head plate provided at its upper end firmly clamp with the connection head. To that Connecting head should be mentioned that this also simple referred to as "head", "head connection" or the like can be. In essence, is suitable as a connection head in the context of the invention, any element on which a Ceiling support is attachable, and in turn to a single Jochträger by means of the holes provided therein is fastened.

The possibility according to the invention, the connection heads each to be attached to a single Jochträger leads compared to DE 100 56 831 C1 to the advantage that the therein shown supporting frame are dispensable, between two Yoke beams are to be fastened. According to the invention can Connection heads comparatively simple and inexpensive be designed by connecting directly to a single Jochträger are fastened. To interact with Markings that can be provided on the yoke beams, can improve on the connection head one each Marking be provided so that if the two Markings are brought into alignment with each other, the Holes of the carrier on the one hand and the connecting head on the other hand are aligned with each other.

The provision of holes at regular intervals along essentially the entire length of the Jochträger leads to one to the advantage that the connection heads almost stepless along the entire length of a yoke beam can be attached. This can be on and the same Schaltisch supports in a flexible manner be attached as they fit for customization different ceiling thicknesses and thus different Concrete pressures is required. In other words, the Distances between the supports as needed to identical designed Schaltisch be made so that a sufficient derivation of the forces occurring over the Support is guaranteed. The attachment of the heads to the Jochträgern is also comparatively fast too accomplish, for example, only bolts through Holes in the connection head on the one hand and the On the other hand, yoke beams have to be inserted and secured. This leads to a considerable time saving compared to the Attachment by means of metric screws, which are threaded into are to turn the yoke carrier.

The continuous formation of holes at the yoke beams In addition, it offers the advantage of having numerous add-on parts can be easily attached to the yoke beams. For example, via the holes a so-called Post connection to be mounted such that a support in a tilted orientation can be connected to a Schaltisch on the ground in the horizontal direction both secure against pressure and tension and / or adjustment operations make. Furthermore, by means of the holes easily Connections of different elements by means of Connecting straps possible. About connecting straps can For example, two adjacent Schaltische each other get connected. Furthermore, by means of one or more Connecting straps a compensation formwork element or a Platform can be connected as a stage. A However, such table stage can also directly to the Jochträgern be attached, even for such a Purpose the holes provided in the Jochträger used become. A connecting strap can also be used as an angle strap be formed and in this way the attachment of a Jochträgers serve for so-called beams. This acts These are scarf sections that are on a deeper level Level than the level of the actual slab formwork are located. It should also be noted that for the drilling of the Jochträger the switching table according to the invention is preferred that they be provided with a division of division common steel wall bolt corresponds. This is it essentially around the steel girders of Wall formwork elements. In a novel way the this customary division between the holes used can, numerous attachments, which are in the range of Wall formwork have proven useful for the invention Schaltisch be used. Thus, the total is the Usability of a switch table together with others Formwork components expanded, and it becomes more efficient Way, greater flexibility in the use of a Schisch achieved. It should also be noted that on the Schaltisch instead of individual supports also one or more Frame elements may be provided which the function take over several supports and / or the Schaltisch and individual supports are interposed.

Preferred developments are in the further claims described.

For the Jochträger is preferred that these at least one U-profile have. Here is the "bottom" of U usually largely perpendicular to the formlining aligned so the holes in this "bottom" are formed. The legs of the U can be in Advantageous for the connection of two U-profiles with each other and / or the connection of the Jochträger with the Use cross members and their support at the yoke beams. Furthermore, in particular that leg of the U-profile, which is facing away from the formwork, for the tension of Anchors are used. In this context is for the Schaltisch invention a thought from the field the wall formworks picked up by a plate-like Clamping element of an anchorage is provided so that it is supported on the said leg.

Alternatively or additionally, the yoke beam have at least one forming tube. Also in this Embodiment can be an advantageous design of the Jochträgers realize.

For the bore spacings, as mentioned, it is preferred that these correspond to the hole spacings that on Steel wall bolts are provided. This results in the described advantageous compatibility of the novel Schaltisches with numerous components in the field of Wall formwork.

In the context of the invention it is further preferred that individual Holes are associated with visually perceptible markings. For example, those holes can be special Be marked in "standard situations" for the Attachment of the connection heads are to be used. Under Standard situations here are to be understood that with it In a sense, as standard, the formwork for ceilings up to is to support a certain thickness. Only at thicker ceilings would require more and / or other holes be used to lower in a then required Distance the connection heads for attaching in this Case provide more supports than in the standard cases. The holes to be used here could also be in be suitably marked. By different Colors could be different groups of holes be distinguished from each other, each in particular Cases, i. up to a respective maximum load to choose. In this context, of course just as conceivable that only those holes provided for certain cases. The flexibility of use increases, however, by additional holes are provided, in which case how is preferred, which in certain cases too mark the holes to be used. Finally, one could Bore at the middle of the yoke carrier in a special way be marked to indicate to the workers that here the center is located, and that conversion devices with a limited edition width for the yoke carrier, with which the Shifter is lifted to transfer, at this center are to be set in order to avoid tilting of the Schaltisches. In this context it should be mentioned that supplementary or as an alternative to the previously described markings as well Markers can be provided that are not necessarily associated with individual holes. These Markers can be used, for example, as bearing markings serve to indicate at what points the Schaltisch on underlying Schaltische can be placed, or at which Place on the switch table further Schaltische auflegbar are.

To the basic connection and Anchoring possibilities as extensive as possible from the The area of wall formwork will be used for the Jochträger further preferred that they consist of two profiles consist of 15 cm or less, preferably 10 cm or less and in particular about 5 cm apart are. The two profiles can each be around U-profiles act whose "bottoms" are directed towards each other. These floors can also be called webs, and the "Thighs" of the U, which could extend from the ground also be referred to as flanges. In this way, the respective yoke carrier formed by two such profiles and, as a result, is essentially structured like the so-called steel wall latches of wall formwork elements. This allows the proven connection and Anchoring possibilities at one in this way constructed carrier can be realized in an advantageous manner. The arrangement of the two profiles one in this way constructed carrier comparatively close to each other offers the advantage that the required forces without Intermediate elements and support frames as previously required can be transmitted. In this context is particular note that in a raised off the ground Condition of a shift table from the free ends of some Meters long supports considerable moments from the supports the carriers can be transmitted, resulting in advantageous Way facing away from each of the formwork skin Leg of the U-profiles is added.

For the described construction of a yoke carrier of two Profiles are preferred that they by means of tabs connected to each other, where also the cross member are attached. These flaps can be stiffening ribs and can, for example, on the two profiles be welded to the yoke beam. The connection of Cross beams can be made through holes, each in the Tabs on the one hand and the cross members on the other are formed.

Preferably, the connection heads are detachably connected to the switch table appropriate. This will be a particularly space-saving Stacking for transport and storage of the table achieved by the connecting heads detached from the table become. The connection heads are very fast and easy easily detachable and refastenable, because of this For example, only the insertion or striking of for example, two bolts per connection head is required. This is, after the space-saving Stacking for transport and storage, a fast Completion of the invention Schaltisches am Location itself possible. The space-saving stacking for For example, the transport leads to the advantage that less transport space is needed, and thus the Transport costs can be reduced.

Although it is for the Schaltisch invention only What matters is that connecting heads, the connection with Serving supports, attached to them, is part of a preferred embodiment provided that at least one Connecting head is designed to pivot. This offers the Advantage that the mounted on a Schaltisch supports to save space need not be removed, but can be pivoted so that they are inclined and / or Aligned almost parallel to the formwork. In a Alignment parallel to the formwork can the Schaltisch invention in a space-saving manner be transported and stored. Furthermore, in this Alignment a moving out of a structure, like described in more detail below, also from extremely small openings in the building possible. In one at least tilted alignment of the supports, the Schaltisch of a projectile into an overlying projectile, whose Ceiling is to be brought by himself for example, from the already created floor over a Building opening, such as a window or parapet, is moved out. This process can also be used by a so-called swivel head without dismantling the supports respectively. In particular, due to the fact that the Connection between the connecting heads and the yoke beams can be designed significantly different than in the state of Technique, the invention allows the use of Jochträgern with comparatively low height. This is currently preferred at about 12 cm.

For the described swivel head is preferred that this a locking tab or pawl, the Fixation of the swung-out position of the support with a Exzenterkurve is provided. Under the swung out Position becomes the position in this context understood, in which the supports at an angle of extend about 90 ° to the formwork skin. The latch is on the Swivel head pivotally provided and can by means of described, for example, on a hook-like projection trained eccentric curve with a pin or bolt the counterpart are engaged in such a way that turning the pawl to the locking position increasing pressure of the counterpart on the yoke beam he follows. On the described counterpart can be a support be attached for example by a wedge mechanism, so that thereby the support particularly reliable and strong is fixed.

For the latch described is further preferred that they at least one locking possibility in the pivoted-in Has position of the support. Under the swiveled Position is understood as a position in which the Support with respect to the formwork inclined or parallel extends to this. For example, a lock in a (with respect to the formwork) 10 ° position of the support be provided to a significantly reduced orientation reach the Schaltisches to this example by a window opening in a building in the overlying To implement projectile. Furthermore, as storage and Transport position a catch for the alignment of the Supports should be provided parallel to the formwork.

For the latch, it also offers advantages when these in one swung out position of the support of one at the Connecting head fastened support is curved away. In this Design is not the pawl in unnecessary way diagonally down from the bottom of the switch table before, but settles to a certain extent by the course of the curvature of the Switching on. This will be a hindrance to work prevented in the region of the connection head. Furthermore, will by this "applying" to the Schaltisch the height of the Schaltisches particularly small, so that several Schaltische can be stacked particularly space-saving.

Further advantages can be achieved by an embodiment be in which the connection head at its bottom has at least a comparatively soft support. There the bottom of the connection head, in the state that the supports are removed, the underside of the switch table forms, by such a condition a favorable Stackability can be achieved. With the soft pad can namely the Schaltisch namely on the formwork of a underlying Schaltisches be placed without that the risk of damage to the formwork of the underlying Schaltisches consists. Under comparatively soft is understood in this context that the Edition example of plastic or the like is executed, so that damage caused by the rest a made of steel element on the formwork, the usually made of wood, is avoided. To that previously described, pivotable connecting head, the can also be referred to as a swivel head, it should be mentioned that this also independent of the invention Schaltisch unfolds its advantages. It is thus as stand-alone object a swivel head for the connection described between a ceiling support and a carrier, the both steel and wood, as well as any one may consist of other suitable material, and which head in any combination the preceding and following may have specified characteristics.

As described, the Schaltisch invention unfolds its advantages, especially with regard to Compatibility and connectivity with a variety of Extension units. In a preferred embodiment is therefore provided that the Schaltisch with at least a connection tab and / or at least one Anchoring element and / or at least one stage is provided. This reflects some of the different ones Extension possibilities of the switching table according to the invention as well as the possibility of several, juxtaposed Connecting Schaltische with each other. Towards the Jochträger this, as mentioned, by suitable Connecting straps happen. In the direction vertical For this purpose anchoring elements can be used, the inserted through the holes provided in the yoke beams become. Using the holes in the yoke carrier can Furthermore, an attachment, such as an anchoring element, that is provided in a direction perpendicular to the formwork skin is to be secured against falling down.

Detailed description of preferred embodiments of invention

As can be seen in Fig. 1, the inventive Schaltisch first a formwork skin 12, which in the shown case of a plurality of adjacent to each other arranged shuttering panels consists. When using is This formwork skin is aligned horizontally and serves the Concreting of ceilings. The variety of formwork panels are on attached to a plurality of cross beams 14, which in the case shown made of wood. The cross members stand upright and are in turn largely perpendicular to so-called Jochträgern 16 aligned and attached to this. In which shown embodiment are exactly two Jochträger 16th made of steel. The Jochträger 16 exist in the shown embodiment of two U-profiles 24, whose Trays or webs, as described above, to each other are directed. This results in both the upper and also at the bottom a comparatively wide Bearing surface, which is favorable for the transmission of moments is. At the top of this bearing surface are the Cross member 14 placed and by means of connecting straps 26th rigidly attached to it. The connecting straps 26 are in each case on the two U-profiles of a yoke carrier 16 welded, so by the variety of connections the plurality of connecting straps 26 a firm connection between the two U-profiles arises, and thereby one stable yoke support 16 is generated.

The connecting straps 26 are in the example shown with two largely vertically extending amplification or stiffening ribs provided. Furthermore, they have in their lower section on a paragraph, so that it to the contour the cross member, each at the top and bottom widened straps and in between a narrower bridge have, are adapted. The attachment between the Connecting straps 26 and the cross members 14 takes place by Screw connections. It is final to mention that in the example shown, the connection tabs 26 in left area of the table from the right side to the Cross member 14 abut, and in the right part of the table the Concerns from the left side. Finally is Note that the spacing between the several Crossbeams 14 is irregular to the particular at certain Make the shift table prevailing load situation Take into account. The fastening of the formwork panels, which form the formwork skin 12, takes place otherwise by nails, Screws or the like.

As can also be clearly seen in FIG. 1, the two are Jochträger 16 over substantially its entire length in periodically provided with holes 18, which, like will be explained in more detail below, different Serve purposes. As can already be seen in FIG. 1, done via these holes the attachment of so-called Connecting heads 20, which pivot in the case shown are executed and more precisely from Figs. 2 and 3 emerge. With reference to Fig. 1 should be mentioned that to the Bottoms of the connecting heads each supports (see. Fig. 4) are attachable, so that the entire Schaltisch on can be supported on a substrate. In Fig. 1 is Finally, still recognizable that individual holes visually Perceptible marks 42, in the case shown in the form of Triangles, are assigned to indicate that for example in numerous "standard situations" at these Make the connection heads 20 are to be fastened. To this Purpose, the connection heads each have counter marks, for example in the form of an upwardly tapered Triangle, to easily align with the triangle to allow the yoke support 16, with its tip directed downwards. Finally, at the shown For example, the yoke beams 16 at their respective ends and on the side facing away from the formwork facing 12 legs of the U-profiles provided with further holes 44, which also for the Attachment of various attachments can be used.

In Fig. 2 is a connection head in the form of a detail Swivel head 20 shown, incidentally, regardless of the Schaltisch invention unfolds its advantages. The swivel head 20 consists essentially of a curved or saber-shaped pawl 28 and a holder 46th The holder 46 is essentially double-walled, the two walls are by pins 48, 70 or bolts and Cross sheets joined together and each at the attached to the plate 60 of the holder 46 mentioned below, for example, welded. Between the walls is located the pawl 28. The holder 46 and the pawl 28 are almost independently of each other on a carrier, for example the in 1 recognizable Jochträger 16, by means of bolts 50th appropriate. The bolts 50 are flat at their free end tapered running to the introduction in a To facilitate drilling. Further, they are by a Fuse element 52, such as e.g. a sapwood, against Falling out secured. By attachment by means of Bolts 50 are both the holder 46 and the pawl 28th pivotable or rotatable with respect to the carrier. The in Fig. 2 shown position corresponds to a position in which a Support, which is attached to the holder 46, with respect to a Carrier or shown in Fig. 1 shift table total is swung out, i. in a perpendicular to it Alignment is located. In this orientation, the Shunt supported on a support via the supports become.

The attachment of the supports is essentially by a wedge mechanism. Here, first in Fig. 2 recognizable double wedge 54 from the position shown in Fig. 2 knocked out or moved to the right.

Below is a support with its head plate arranged so to speak below the holder 46, so that in turn the upper edges 56 of the two wedge elements inserted below the top plate and essentially be brought back into the position shown in Fig. 2 can. By the running of the lower wedge surfaces 58 of the Wedge elements on a suitable counter bearing moves the Double wedge 54 increasingly upward and clamps the top plate the support between the upper flanks 56 of the wedge elements and the plate 60 of the holder. This will be a reliable fixation achieved.

The swivel head shown in Fig. 2 is under other synonymous by the fact that at its bottom on both Side angled flanges 62 are formed, with which the swivel head 2 alone or in his at a Schaltisch attached state (see Fig. 1) on a base or also the formwork 12 of an underlying switching table can be hung up. In order to damage this avoid, the said flanges 62 are each with a provided comparatively soft pad 34, which is about the bottom of the respective flange 62, over a part its top and the edge surface extends. After all It should be noted that in FIG. 2 that mark 66 in FIG Shape of an upwardly tapered triangle and in the shown case in the form of an opening in the side wall of the Halters 46 can be seen, the alignment with the Countermarking on a yoke support 16 of the Schaltisches 10th serves.

In Fig. 2 is further a locked position between the Holder 46 and the latch 28 are shown. In this position will the holder 46 including the attached support with its plate 60 firmly against the lower support surface a yoke support 16 pressed so that here a rigid Connection is achieved, with which the occurring Moments can be transferred. In the shown locked state is in the case shown a projection formed eccentric curve 68 with a pin 70 in engagement. This contour is eccentric in that with respect to the axis of rotation of the pawl 28, which by the (in Fig. 2 left) bolt 50 is formed, not circular runs. Rather, the eccentric curve approaches in her Progressing from their free end increasingly to the Axis of rotation, so that when "tightening" the holder 46, i. by a rotation of the pawl of FIG. 2 against the Clockwise, an increasing tensioning of the holder 46 in Direction of the yoke wearer takes place. This puts together with the yoke beam 16 a solid connection safely.

For releasing and pivoting the holder 46 from the in Fig. 2 shown position, the latch 28 is initially a little raised so that the cam 68 of the pin 70th is disengaged. The rotation in the direction of Clockwise is thereby by the upper area recognizable pin 48 limited. After releasing the holder 46 and the attached thereto support, not in Fig. 2 is shown by a counterclockwise rotation be pivoted, i. be put in a position in which they (see Fig. 1) inclined relative to the Jochträgers 16 or even aligned parallel to it. In the context of this Pivoting movement of the upper pin 48 of the holder 46 runs in Essentially on the upper edge 72 of the pawl off and twist it counterclockwise. Due to the against End of this movement assumed center of gravity of the pawl then the latch falls when the pin 48 in the latch formed recess 74 reaches a small piece in Clockwise direction back and locked so that Holder 46 and the attached support in one certain position. This may, for example, to act a 10 ° position with respect to the yoke carrier. By Continuation of the pivoting movement, the pawl released again and continue to be deflected, leaving another recess 76, also, as described, due to Center of gravity position, in engagement with the pin 48 device and the Holder 46 including the attached support for example, locked in a position in which they are extends substantially parallel to the yoke support 16. In this Position is the space requirement of a Schaltisches with it attached columns significantly reduced, so that For example, a moving out of the Schaltisches, without the supports must be removed from one Building opening (as well as in the inclined, for example 10 ° position of the support) as well as in the parallel position a storage as well as a moving out of a particular small building opening is possible.

In Fig. 3 is shown for clarity in FIG Swivel head 20 shown in a side view. As mentioned, the pawl 28 extends curved so that they from a mounted on the holder 46 support is curved away and attached to a (in the shown Alignment horizontal) Jochträger 16 "applies". hereby as little obstruction of work as possible takes place in the Area of the holder 46, for example in the context of Fixing a support, must be made. In Fig. 3 is well formed on a projection 78 Exzenterkurve 68 to recognize, which for the engagement with the Pin 70 provides.

In Fig. 4, the switching table 10 is in use shown. At the connecting heads 20 are supports 22nd mounted over which the Schaltisch on a substrate 80, for example, the concrete ceiling of an underlying Projectile, is supported. In the area of the free end of the Ceiling is a guardrail 82 provided. As it is at the table shown in Fig. 4 to the "last table" on the edge a ceiling to be concreted 84, must be a Attach in a horizontal direction. this happens in the example shown by a tension belt 86, the a holder 88 is attached to the ceiling 80, the Substrate forms, is fixed. It should be mentioned that in the Schaltisch according to the invention in a favorable manner by means of Holes 18 in addition to or instead of the tension belt 86th the connection of a (inclined) support can be made, which can take over the horizontal fixation. By the Use of a support results in addition to one pressure-resistant fixation.

In the upper right area of Fig. 4 are different To recognize attachments, in a favorable manner to the Schaltisch invention 10 can be attached. This is, for example, a stage stage 40, either directly or, as shown in Fig. 4, over one or more connecting tabs 36 on the switch table can be attached. For this purpose, the Holes 18 used, which is essentially the entire length of the Jochträger 16 extend. Because of that Jochträger 16 is constructed substantially as the out in the field of wall formwork known steel wall bars can appropriate anchoring elements are used. In which shown example, an anchoring element 38 with a Hammer head 90 (see Fig. 5) clamped such that a Edge formwork 92, the edge of the ceiling to be concreted 84th defined, anchored. Here it shows in especially the cheap usability of common Components in a novel manner on a Deckenschaltisch 10th Further, in the left portion of Fig. 4 is a connection of two Schaltischen each other, in the direction of the Jochträger 16, to recognize. This connection is in Fig. 6 with a Length compensation shown and described below. Out Fig. 4, however, arises as this connection between two Schaltischen without length compensation can be displayed. In particular, the existing holes 18 are used, and at a Connecting tab trained holes arranged so Be that correct alignment of the two tables gives each other.

Fig. 5 serves to illustrate the anchoring of Edge form 92 by means of the hammer heads 90, each supported on the lower support surface of the Jochträger 16. The Fixation of a prefabricated formwork element 94 takes place by angle bracket 96, which, as mentioned, by means of Anchoring elements 38 on the Schaltisch invention are anchored.

In Fig. 6 is shown how two Schaltische 10 for a with each other and with another with a compensating tab 98th can be connected. In the case shown serves the Equalizing tab 98, in a favorable manner by means of the Jochträgern 16 existing holes are attached can, the laying on of other cross member 14 via brackets 100, such that a balancing formwork element 102, typically a formwork panel can be hung up. It is, however, without Further recognizable that shown in Fig. 6 Equalizing tab 98 replaced by a connecting strap could be, which the two Schaltische 10 directly connects together so that a continuous formwork skin 12 arises. For this purpose, only the holes on the Form connecting tab so that the two Schaltische 10 are arranged with respect to each other so that the Scarf skins of both tables are aligned directly with each other. The connection between any tab and the Jochträgern can be done by bolts 50, as shown in FIG. 2 are shown for the swivel head. Through the conical end results in a simple manner a correct Alignment of the elements to be connected to each other.

In Fig. 7 is additionally the connection of two Schaltische in Direction of the cross member 14 shown while the situation in Fig. 6 shows the connection of two Schaltische 10 in the direction of Jochträger 16 was concerned. In the direction of the cross member 14, so perpendicular to the yoke beams, this connection can be made by a Anchoring element 38 done, in a favorable manner by put the existing in the Jochträgern 16 holes and can be clamped by suitable clamping devices. In FIG. 7 shows an embodiment in which the respective Schalhäute 12 a small piece in front of the respective Cross members 14 ends, so that a compensation switching element 102nd is required. Such a compensation switching element 102nd For example, it may be necessary to make an adjustment make given space geometries. It goes without saying, that the two Schalhäute 12 also a small piece could extend beyond the cross member 14, so that in Connected state immediately a continuous formwork skin is trained.

In Fig. 7, the positional relationship between the respective yoke carrier and the swivel head 20 to recognize. It shows that the swivel head 20 with the two Side plates of the holder 46 between the U-profiles of the Jochträgers 16 is arranged and in the tensioned state with its top plate 60 fixed to the bottom Support surface of the yoke carrier 16 rests. This is going through formed the two lower legs of the U-profiles.
