Abstract

The invention relates to a support device (10) for fastening railings and/or shuttering elements for the erection of multi-storey buildings, having a vertical support member (34) extending over more than one floor height. A clamping device (12) holding the lower region of the vertical support member is provided and is designed to releasably fasten the vertical support, without guying, to just a single building ceiling (36) or floor slab.

Description

The invention relates to a carrying device for fastening railing and / or formwork elements for the construction of multi-storey buildings, with a vertical support extending over more than one storey height. Furthermore, the invention relates to a formwork system.

In accordance with current regulations, fall protection must be provided when creating formwork for building ceilings. For this purpose it is e.g. customary to create a bottom-supported external scaffolding, which projects beyond a newly created building ceiling so far that the required fall protection can be installed before the installation of the necessary for the building ceiling formwork elements on the outer frame. Alternatively, vertical carriers are each attached to a plurality of already completed building ceilings, which in turn protrude above the next, to be created building ceiling, so that there already a fall protection can be provided before the formwork elements are mounted for the next building ceiling.

A disadvantage of these known fall protection is that they are complex to create. When using an external scaffolding, a large number of scaffolding elements must be provided and installed, especially in higher buildings, even if the scaffolding is ultimately not required for work on the exterior facade. In the alternative use of projecting beyond the building ceiling to be created vertical beams, it is also complex, this floor by floor to implement above, in particular, since the vertical support must be attached to each of several, already completed building ceilings. Furthermore, it is known from the prior art according to DE 10 2005 045 527 AI, to erect a protective wall on the outer sides of a building to be created, which is anchored to two superimposed, already created building ceilings by means of cantilevers and after building a building ceiling for Erection of another building ceiling can be raised by means of a drive around the corresponding floor height. At the upper end of this protective wall are fixed platforms secured by railings, which ensure access to the new building ceiling.

Even with this protective wall, the adaptation to the respective newly to be created next higher floor designed very complex, since all belonging to a particular barrier drives must be operated more or less synchronously. In addition, at each building ceiling several attachment points in the form of concreted cones or holes must be provided. On each newly created building ceiling finally more Kragträger must be fixed to allow a new lifting to the height of the next, to be created building ceiling.

It is therefore an object of the invention to provide an easy-to-build fall protection for the creation of slab formwork for multi-storey buildings, which is already used for the first building ceiling to be created.

The object is achieved by the features of claim 1 and in particular by a support device of the type mentioned, the is characterized by a holding the lower portion of the vertical support clamping device, which is adapted to releasably attach the vertical support to only a single building ceiling or floor plate.

The support device according to the invention is characterized in that it can be mounted in the manner of a screw clamp only in an area of a single building ceiling, ie without supports that would have to be attached to two or more superimposed building ceilings. In addition, it is not absolutely necessary to clamp the attached to a single building ceiling support device in addition to this building ceiling, so that ultimately a non-tension attachment is possible. If necessary, however, at least one additional bracing between the support device and the building ceiling can also be provided. The support device according to the invention thus provides a stable, relatively easy and quick to install mounting option for at the height of the next, yet to be concreted bullet to be mounted railing elements for securing the concerned with the formwork creation and concreting persons ready. At the same time, formwork elements for the next building ceiling to be created can be fastened to the support device so that the same can then assume a further function in addition to the provision of an attachment possibility for railing elements without great additional expenditure.

According to a preferred embodiment, the clamping device has at least one first and at least one second horizontal cantilever and a tensioning device, in particular a spindle for generating a force acting between the cantilevers force around the

Clamp clamping device to a building ceiling. This will a simple to manufacture, but still secure attachment of the support device on the building ceiling in the manner of a screw clamp achieved without mandatory special mounting positions, such as concreted cones or holes must be provided in the building ceiling.

Preferably, the clamping device is provided on the upper cantilever and effective in a mounting position between the upper cantilever and the top of a building ceiling. In this embodiment, the clamping device is particularly well accessible from that building ceiling from where the support device is clamped.

Preferably, the upper and lower Kragträger are vertically adjustable relative to each other. This makes it possible to adapt to different thicknesses of building ceilings or an interlocking fastening of two mounted on a building ceiling corner support devices, in which between the two cantilevers of a support device not only the building ceiling, but in addition a lower or upper Kragträger the other, about Corner mounted carrying device comes to rest.

According to a further preferred embodiment, the lower cantilever has a plurality of support points for resting on the underside of the building ceiling and the tensioning device of the upper cantilever at least one support point for resting on the top of the building ceiling, wherein the support points of the lower cantilever span a surface. As a result, tilting moments acting on the vertical carrier in different directions are reliably intercepted. In this embodiment, it is sufficient to provide only a single clamping device, as a tilt-stable and secure against rotation of the support device is given by the flat support on the underside of the building ceiling.

It is preferred if the clamping device has two lower, parallel to each other extending and spaced apart Kragträger, which abut in a mounting position on the underside of a building ceiling. Thus, a sufficiently flat plant is guaranteed.

In an advantageous embodiment, the clamping device has a base body, on which the or the lower Kragträger fixed and the upper Kragträger is mounted vertically adjustable. In this way, in a pre-assembly, in which the lower cantilevers are already near the bottom of the building ceiling, a frictional connection is not yet established, a necessary to adapt to the thickness or thickness of the building ceiling vertical adjustment of the upper cantilever preferably from the top the building ceiling are made from. This facilitates the mounting of the support device, since initially a comparatively large distance between the lower and upper cantilevers can be adjusted, which facilitates the threading on the building ceiling. Subsequently, the adaptation to the thickness of the building ceiling takes place. In principle, however, it would also be possible to fasten the upper cantilever beam fixedly and the lower cantilever beam vertically adjustable on the base body. According to a further advantageous embodiment, the vertical support is adjustable relative to the clamping device in the vertical direction and / or tiltable about a horizontal axis. As a result, in particular, an accurate vertical and / or horizontal adjustment of formwork elements can take place, which can be fastened to the vertical support as part of a formwork for the next building ceiling. Preferably, the vertical support is releasably received in its lower end portion in a coupling sleeve. This makes it possible to separate the vertical support for transport purposes of the clamping device and to mount different length vertical support on the same clamping device to adapt to different floor heights.

It is preferred if the coupling sleeve in the vertical direction adjustable and / or disposed about a horizontal axis tiltable on the clamping device, wherein the clamping device comprises an adjusting device for a height adjustment or tilt adjustment of the coupling sleeve, in particular in each case a spindle for each adjustment. For compensating for deformations by forces exerted on an end formwork fastened to the vertical support, the vertical support can also be prestressed by means of the inclination adjustment.

Advantageously, a spaced from the lower end portion of the vertical support is slidably received in a direction of the clamping device guide sleeve in the vertical direction, wherein preferably the guide sleeve with respect to the clamping device in the horizontal direction is adjustable, in particular by means of a spindle. The guide sleeve thus allows a relative to this vertical displacement of the vertical support and still ensures a secure fixation in the horizontal direction. By means of the horizontal adjustment of the guide sleeve, the angle of inclination of the vertical support with respect to the clamping device, ie be changed to the building ceiling, so that ultimately a horizontal adjustment of a fastened to the vertical support formwork element can be done. According to an advantageous embodiment, the coupling sleeve and / or the guide sleeve are arranged on the base body, wherein preferably the coupling sleeve is height-adjustable with respect to the base body. For height adjustment may also be provided a spindle. The coupling sleeve can be designed both with and without bottom.

The vertical carrier preferably has one or more vertically spaced mounting positions in an upper region for fastening railing and / or formwork elements. In the case of several attachment positions which can be used as an alternative to one another, the height of the railing and / or formwork elements can be adapted to the floor height of the new building ceiling to be created. According to a further advantageous embodiment, the upper and / or lower cantilever beams have bores for screw fastening to the top of a building ceiling or floor plate. As a result, the carrying device of the same type can be used both for the above-described clamp fastening and in cases in which it is not possible to reach around the building ceiling or floor slab, for example in the presence of wall sections immediately below the building ceiling or even when attached to a bottom plate is the case. Advantageously, the maximum vertical distance of the upper and lower Kragträger is greater than / equal to the strength of a building ceiling plus the height of at least one Kragträgers. This results in a very variable use of the support device, as cantilevers can cover two adjacent support devices, as may be required in particular in an arrangement over the corner. For example lie only the lower cantilever of a first support device directly to the underside of the building ceiling, while the lower cantilever beams of a second support device abut the lower cantilever beams of the first support device. In order to ensure a secure attachment to the building ceiling with several support points for both support devices, it may be necessary under certain circumstances, to use on the underside of the building ceiling spacers whose thickness is at least equal to the strength of a lower cantilever. In this case, then the lower cantilever beams of the second support device are not on the lower cantilever beams of the first support device, but at one or more spacers.

In a further advantageous embodiment, the support device comprises a vertical carrier fastened Gelä derelement, which comprises a vertical profile with a plurality of attached vertically spaced apart horizontal profiles, the free end portions with respect to the vertical profile in opposite directions. This railing element is a fall protection, which is particularly easy to assemble, since it must be attached to only a single vertical support.

Preferably, provided in an upper region of the vertical support, vertically spaced mounting positions for a railing element are adapted to the distance of the horizontal profiles, which can extend in a mounting position of the support a horizontal profile with its free end between two horizontal profiles of a railing element of a neighboring mounted support device. This configuration makes it possible to freely choose the distance between two adjacently mounted carrying devices at least within a certain range, without holding railing elements of different widths or gaps between adjacent railing elements must occur. As it were, there is an entanglement of the horizontal profiles of adjacent railing elements, wherein all horizontal profiles can be located in the same vertical plane.

Preferably, two horizontal profiles, pointing in opposite directions, of a railing element are alternately offset from each other. Thus, an entanglement or toothing of adjacent railing elements is possible even if they are each mounted at the same height on their respective vertical beams.

However, it can also be provided that in each case two horizontal profiles are arranged offset each other without offset or a continuous horizontal profile is fixed in its central portion on the vertical profile. In this case, the desired entanglement of the horizontal profiles of adjacent railing elements is then achieved in that the attachment positions of adjacent railing elements are offset slightly relative to each other at their respective vertical supports in the vertical direction, said offset may preferably be about half of the vertical distance of the horizontal profiles from each other.

It is advantageous if the railing element comprises at least one coupling element which is provided for releasably coupling at least one free end region of a horizontal profile with at least one free end region of a horizontal profile of a further adjacently arranged railing element. As a result, the stability of the railing elements can be further increased, since the risk of bending is reduced when larger forces occur. Preferably, the railing element by means of securing bolts or by means of a clamping connection on the vertical support of the support device can be fastened. The invention further comprises a formwork element, in particular an end formwork, with coupling means for attachment to a railing element according to one of claims 10 to 12. Such formwork elements can be connected to the attachment of the support device to a building ceiling or floor plate and to the attachment of the country element Mount on the support device, so that the construction of the slab formwork can be simplified by the inclusion of the support device as a structurally effective element.

Preferably, the coupling means comprise hooks for coupling to a horizontal profile of the railing element. The formwork element can thus be easily hooked into the railing element, for example by means of a crane, whereby a very simple and quick attachment of the formwork element is achieved on the railing element. In another advantageous embodiment, the formwork element has a plurality of first hooks and a plurality of second hooks, which can each be coupled with different horizontally and possibly also vertically spaced apart areas of one or more railing elements. When the respective hooks are hooked on opposite sides of the vertical beam, a high stability is achieved both with respect to a vertical axis, ie torsional stability. When the hooks are coupled to vertically spaced portions of one or more railing elements, a torsional stability with respect to a horizontal axis, ie tilt stability, is achieved. The object of the invention is further achieved by the features of claim 13 and in particular by a formwork system with a plurality of supporting devices, each comprising a railing element according to one of claims 7 to 9 and at least one formwork belt according to one of claims 10 to 12. In such a formwork system the slab formwork only has to reach to the front formwork. A shuttering serving as shuttering formwork element is simply attached to the railing element. It is no longer necessary to provide the slab formwork with a projection, which is required in conventional formwork systems for fastening the Stirnabschalung. The formwork system according to the invention makes it possible to first produce a border of Stirnabschalungselementen whose interior is subsequently filled with slab formwork elements. According to a preferred embodiment of the formwork system, the horizontal profiles of the railing elements are alternately offset from each other with their one end portion on two opposite sides of the vertical profile. The formwork element has in this case a plurality of hook arrangements, which each comprise at least a first hook and at least one second hook, wherein the first and second hooks of a respective hook arrangement are horizontally spaced apart and have a vertical offset from one another. This vertical offset corresponds to the alternate displacement of the horizontal profiles, so that the hooks are preferably suspended immediately adjacent to the vertical carrier when coupled with a railing element on two pointing in opposite directions horizontal profiles.

In addition to the areas provided for the hooks, the railing element preferably has a contact surface for supporting the formwork element below the hooks. Further advantageous embodiments of the invention are specified in the subclaims, the drawings and the description of the figures. The invention will be described below with reference to the drawings. Show it:

Fig. 9 is a side view of the support device according to the invention in an alternative mounting state.

A supporting device according to the invention comprises according to Fig. La to le a clamping device 12, which comprises two vertically extending, spaced-apart base body 14, at the lower end portions in each case a horizontally extending lower cantilever beam 16 is attached. Of the two basic bodies 14 and lower Cantilevers 16 is in the side views of Fig. La to lc only one visible. As can be seen in particular in FIGS. 1 d, 1 e and 3, the two base bodies 14 and lower cantilever beams 16 are connected to one another via webs 38.

Between the base bodies 14 is a vertically adjustable (see double arrow in Fig. La) and pivotable about a horizontal axis (see double arrow in Fig. Lb) upper cantilever 18 is arranged. For this purpose, the base bodies 14 have a plurality of horizontally spaced, horizontal bores 20 for receiving securing bolts 22 for the

Attaching the upper Kragträgers 18 in the respective desired vertical position. Two different vertical positions are shown once in FIGS. 1a and 1b with solid lines and once with dashed lines. The securing bolt 22 can be passed through these holes 20 and also vertically spaced from each other, horizontal holes 20 of the upper Kragträgers 18.

If both securing bolts 22 are passed through the holes 20 in the upper cantilever beam 18, this is verschwenksicher fixed to the basic bodies 14 (Fig. La). In the illustrated in Fig. Lb adjustment position of the lower locking bolt 22 is pulled out of the bore 20 of the upper Kragträgers 18. After the upper cantilever beam 18 has been pivoted slightly upwards, which is indicated by the double arrow, the withdrawn lower securing bolt 22 has been inserted back into one of the holes 20 of the main body 14, so that this now a stop for the upwardly pivoted upper cantilever 18th forms and keeps him in the pivoted position shown in FIG. Lb. The associated increase in the distance between the upper Kragträger 18 and the lower cantilevers 16 facilitates the installation of the clamping device 12 to an existing building ceiling. At the free end of the upper Kragträgers 18, a clamping device 24 is provided, which is shown in the embodiment as a spindle. In principle, however, other, preferably self-locking Ver adjusting agents can be used. The lower end portion of the clamping device 24 has a support 25 for the top of the building ceiling.

At the lower Kragträgern 16 opposite side of the base body 14 is a coupling sleeve 26 for receiving a vertical support 34 (see Fig. Lc) arranged. The coupling sleeve 26 is vertically adjustable by means of adjusting means, not shown, with respect to the base body 14 in height. The vertical support 34 as well as the coupling sleeve 26 is provided with holes 20 a and 20 b for securing bolts 22 for mutual locking. There is a certain play between the vertical support 34 and the coupling sleeve 26, so that the vertical support 34 can be pivoted by a small amount about the locking pin 22 locked in the coupling sleeve 26. The coupling sleeve 26 has in the embodiment on a bottom, which, however, can also be omitted.

For completeness, it should be mentioned that each of the holes 20, 20a, 20b may have a different diameter, especially if they are located on different components. At the upper end portion of the base body 14, a frame-shaped support member 28 is fixed, in which a guide sleeve 30 is slidably received horizontally in the main extension direction of the cantilever beams 16, 18. For horizontal adjustment of the guide sleeve 30 between the guide sleeve 30 and the bodies 14 effective spindle 32 is provided. Referring now to Fig. Lc, the various adjustment options that are provided in the clamping device 12, again explained. Within the circle A, a double arrow F is shown, which indicates the vertical adjustment of the tensioning device 24 and the upper Kragträgers 18.

First, a coarse adjustment of the distance between the cantilevers 16, 18 by selecting a suitable pair of holes 20 in the base body 14, in which the locking pins 22 are inserted.

In order to achieve the mounting position shown in FIG. 1c, the clamping device 12 is then first pushed or "threaded" onto the existing building ceiling 36 (FIG. 1c) with the upper cantilever 16 pivoted upwards (FIG. 1b). This relative movement between the building ceiling 36 and the clamping device 12 is indicated in Fig. Lc with the arrow in the mark B.

Subsequently, the upper cantilever beam 18 is pivoted downwards into the working position according to FIG. 1 c and fixed with a second (lower) securing bolt 22.

Then, the clamping device 24 is actuated, so that the support 25 moves in the direction of the arrow F down and the building ceiling 36 is clamped between the lower cantilever beams 16 and the support 25. The sufficiently dimensioned surface defined by the two lower cantilever beams 16 ensures reliable fixing of the clamping device 12 on the underside of the building ceiling 36 so that tilting of the clamping device 12 about a horizontal axis is ruled out. The double arrow bounded by the mark C symbolizes the subsequently possible vertical adjustment of the vertical support 34 via a corresponding vertical displacement of the coupling sleeve 26 by means of a spindle (not shown). Finally, the double arrow bounded by the mark D indicates the further possible tilt adjustment of the vertical support 34 with respect to the base body 14 fixed to the building ceiling 36 by means of the spindle 32. The meaning of these adjustment possibilities of the vertical support 34 will be explained below.

FIGS. 1 d and 1 e show an arrangement of two clamping devices 12, 12 'designed largely in the manner described above for an over-corner fastening on an outer corner of the building ceiling 36, in which the lower cantilever beams 16 are due to predetermined space conditions or for static reasons , 16 'must overlap. Fig. Ld shows the mounted on the building ceiling 36 arrangement obliquely viewed from below with a view towards the underside of the building ceiling 36, while in Fig le the arrangement without the building ceiling is seen obliquely from above.

For this purpose, the lower Kragträger 16 'of a clamping device 12' on its upper side with two spacers 39 are provided. The spacers 39 have a T-shaped configuration, wherein the transverse bar of a T performing portion rests on the two cantilevers 16 'and a foot of a T performing section between the cantilever 16' protrudes and to the cantilever 16 'connecting webs 38th is fastened for example by means of screwing. The transverse bar of a T performing section is at least as strong as the cantilever 16 of the other clamping device 12 so that the support base of the cantilever 16 'on the underside of the building ceiling 36 in an outer corner mounting of FIG. Ld in comparison to one of - Final edition of the cantilever beams 16 is increased accordingly in a mounting without spacers and corresponds to the spanned by the two spacers 39 surface.

Referring now to FIGS. 2 to 7, the structure of a shuttering system according to the invention will be explained in more detail.

On an existing building ceiling 36 on which pillars 40 have already been erected as a support for a new building ceiling to be created, a plurality of clamping devices 12, vertical beams 34 and handrail elements 42 and shuttering elements 44 to be described in more detail are provided (FIG. 2). In each case a clamping device 12 and a vertical carrier 34 are joined together to form a carrier device 10 (FIG. 3).

As can be clearly seen in FIG. 3, a railing element 42 is fastened to an upper end region of the vertical support 34. In order to enable at least a large-scale adaptation to the desired storey height of the new building ceiling to be created, both the upper end region of the vertical support 34 and a vertical profile 46 of the railing element 42 are provided with a plurality of vertically spaced-apart bores 20. The attachment takes place by means of security bolts which can not be recognized here, which are inserted through the bores 20 of the two parts 34, 46 to be connected.

A plurality of vertically spaced horizontal profiles 48 are attached with its one end portion to the vertical profile 46. The other End area is free. The horizontal profiles 48 extend alternately in opposite directions, ie between two horizontal profiles 48, which point in one direction, there is a horizontal profile 48, which faces in the opposite direction, so that the horizontal profiles 48 on both sides of the vertical profile 46 each offset are arranged.

At the preassembled supporting device 10, in the region above its center of gravity, a carrying cable or carrying chain 50 of a lifting device is fastened in order to transport the carrying device 10 into a mounting position according to FIG. 4 (see upper carrying device 10). To attach the support chain 50 to the vertical support 34 is provided with an eyelet for suspending the support chain 50 fastener 51 is provided, which by means of a safety pin 22, in a above the

Focus of the support device 10 is added in the vertical support 34 introduced further bore 20a is fixed to the vertical support 34 (Fig. 3). The support device 10 is clamped in the manner described above to the existing building ceiling 36. These steps are repeated until the building ceiling 36 is provided along its respective desired peripheral area with supporting devices 10 (Figure 5). It is possible to use two or more supporting devices 10, e.g. by means of diagonal struts (not shown) to couple into a unit and to mount these coupled support devices 10 together

and / or convert from one building ceiling to the next, which reduces the time required for assembly or implementation.

In Fig. 5 can be clearly seen that the railing elements 42 already form a complete fall protection for work on a still to be created slab formwork. In particular, it is easy to see how the zontalprofile 48 of a railing element 42 extend between the horizontal profiles 48 of an adjacent railing element 42, without the need for an adjustment of the railing elements 42 in dependence on the distance of adjacent support devices 10. As a result, it is also not necessary to pay attention to a precise adherence to a predetermined grid temperature when fastening the carrying devices 10 to the building ceiling 36. Only a predetermined by the width of the railing elements 42 maximum distance is taken into account. Alternatively, instead of the railing elements 42, railing elements 42 'according to FIG. 8 can be used, in which, in contrast to the railing element 42 (FIGS. 2 to 7), two horizontal profiles 48 pointing in opposite directions are arranged without offset on the vertical profile 46. Optionally, instead of two individual horizontal profiles 48, a continuous horizontal profile can be used.

When using railing elements 42 'without offset of the horizontal profiles 48, the desired entanglement of the horizontal profiles 48 adjacent railing elements is achieved by the attachment positions of adjacent railing elements at their respective vertical beams 34 in the vertical direction are slightly offset from each other, said offset preferably about half of vertical distance of the horizontal profiles 48 may be from each other.

Especially when looking at the outer and inner corner regions (FIG. 5), it becomes clear that building ceilings 36 of arbitrary dimensions can be created and secured with both railing element variants without the need for specially adapted railing elements 42, since the horizontal profiles 48 of adjacent railing elements 42 both at Order on a long side of a building ceiling 36 as well as in shown in Fig. 5 outer corner (see arrows A) and inner corner arrangements (see arrow B) smoothly intermesh with each other over a wide distance range at an angle.

To increase the stability of the protective railing, additional coupling means can be provided between individual horizontal profiles 48 of adjacent railing elements 42. However, this is not absolutely necessary due to the torsional rigidity of the vertical supports 34 and the bending stiffness of the horizontal profiles 48.

After mounting the support devices 10 together with the railing elements 42 formwork elements 44 can now be suspended in the railing elements 42.

In the embodiment shown in FIG. 5, a formwork element 44 each comprises three formwork panels 54, which are rigidly coupled together by means of several continuous, arranged on the back of the formwork panels 54 Koppelpro file 56. In principle, the use of formwork elements with a different number of formwork panels 54 is possible. For example, a formwork element with only one formwork panel 54 can be used.

Also on the rear side of each formwork panel 54 are provided hooks 52a, 52b which have a vertical offset with respect to one another which corresponds to the offset of the horizontal profiles 48 fastened on opposite sides of the vertical profile 46.

So that the guardrail has a sufficient effective height, the formwork elements 44 are preferably in the respective lowest Horizontal profiles 48 mounted. A contact surface 60 provided on the vertical profile 46 ensures reliable vertical alignment of the formwork elements 44 (see also FIGS. 3 and 8). After all shuttering elements 44 have been hooked into the corresponding railing elements 42, according to FIGS. 6 and 7, a supporting structure 62 for a slab formwork can be erected. Formwork floor elements 64 can now be attached to this support structure 62. In order to ensure a support of the shuttering floor elements 64 in the edge region, the shuttering panels 54 are provided on its front side with a support 58 for the shuttering floor elements 64.

From Fig. 6 it can be seen that by means of the vertical and tilt adjustment of the vertical support 34, an exact and fine-level adjustment or leveling of the formwork elements 44 in relation to the height and the lateral dimensions of the new building ceiling to be created is possible.

Finally, the formwork created in this way can be filled with concrete 66 (FIG. 7), which forms the new building ceiling to be created after hardening. In order to avoid that individual formwork elements 44 are pressed outwards as a result of the load of the concrete 66, the inclination adjustment of the vertical support 34 makes it possible to exert an additional pretension on the formwork elements 44, so that the predetermined dimensions for the new building ceiling to be created can be maintained.

If higher loads are to be intercepted during concreting, all or part of the supporting devices 10 on the existing building ceiling 36 in addition to the attachment by means of the clamping device 12 can also be removed, as shown in Fig. 9. For this purpose, the carrying cable or the carrying chain 50 can be used, which was already hooked with its one end in the fixed to the vertical support 34 fastener 51 for the previous transport. The vertical support 34 is provided with a plurality of vertically spaced holes 20 a, which optionally allow a selection of another fastening position for the fastening element 51 (see also Fig. 3). As a rule, however, no re-assembly of the fastening element 51 takes place.

The other end of the support chain 50 is suspended in an adjustable clamping element 68, which in turn is mounted in a fastened to the building ceiling 36 coupling element 70. By pressing the clamping element 68, a tensile force is exerted on the vertical support 34 via the support chain 50 and the support device 10 is biased accordingly.

With the formwork system according to the invention, it is therefore possible to create a formwork for a newly created building ceiling and at the same time to establish a fall protection for work on this slab formwork or for the concreting of the building ceiling.
