Abstract

The invention relates to a support 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. In this case, a clamping device is provided which holds the lower region of the vertical support and is designed to releasably attach the vertical support without tension to only a single building ceiling or floor slab.

Description

The invention relates to a support device for fastening railing and / or shuttering elements for the creation of multi-storey buildings, with a extending over more than one storey height vertical beam. 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 z. B. 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 beams 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 shuttering 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 extending beyond the building ceiling to be created vertical girders, it is also expensive to implement them floor by floor up, in particular, since the vertical support must be attached in each case to several, already completed building ceilings.

Furthermore, it is known from the prior art DE 10 2005 045 527 A1 known to erect a protective wall on the outsides of a building to be created, which is anchored to two superimposed, already created building ceilings by means of cantilevers and can be raised after erecting a building ceiling for the construction of another building ceiling by a drive to the corresponding floor level. 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 the object of the invention to provide an easy-to-install 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, which is characterized by a lower portion of the vertical support holding clamping device, which is adapted to the vertical support to only a single building ceiling or floor plate to releasably fasten.

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, but also at least one additional bracing between the support device and the building ceiling can 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 attached to the support device, so that selbige then without much additional effort in addition to providing a mounting option for handrail elements can still take on another function.

According to a preferred embodiment, the clamping device has at least a first and at least a second horizontal cantilever and a tensioning device, in particular a spindle for generating a force acting between the cantilevers force to clamp the clamping device to a building ceiling. As a result, a simple to manufacture, but still secure attachment of the support device on the building ceiling in the manner of a screw clamp is achieved without necessarily special Attachment positions, such. B. 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 the building ceiling from where the support device is clamped.

Preferably, the upper and lower Kragträger are vertically adjustable relative to each other. This allows adaptation 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 supporting device not only the building ceiling, but also a lower or upper Kragträger the other, mounted on the corner 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, since 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, mutually parallel and spaced-apart cantilevers, which rest 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 tilted 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 is adjustable in the vertical direction 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 inclination angle of the vertical support with respect to the clamping device, d. H. 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 with respect to the Main body is height adjustable. For height adjustment may also be provided a spindle. The coupling sleeve can be designed both with and without bottom.

Preferably, the vertical support in an upper region one or more vertically spaced mounting positions for attachment of 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 support device of the same type can be used both for the above-described clamp mounting and in those cases in which an encompassing the building ceiling or floor plate is not possible, as for example in the presence of wall sections immediately below the building ceiling or just in one Attachment to a base 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, only the lower cantilevers of a first support device lie directly on 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. To ensure a secure contact with the building ceiling with multiple 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 Kragträgers. 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 carrying device comprises a railing element which can be fastened to the vertical carrier and which comprises a vertical profile with a plurality of horizontally spaced-apart horizontal profiles whose free end sections point in opposite directions with respect to the vertical profile. 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 support devices at least within a certain range, without having to provide railing elements of different widths or gaps between adjacent railing elements. 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 to 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 by slightly displacing the attachment positions of adjacent railing elements at their respective vertical supports in the vertical direction, this offset preferably being approximately half the vertical distance of the horizontal profiles from one another.

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 safety bolts or by means of a Clamping on the vertical support of the support device 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 fastening of the support device to a building ceiling or floor plate and to the attachment of the railing element to the Mount the supporting device, so that the construction of the slab formwork can be simplified by the inclusion of the supporting device as a statically 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, z. B. 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, i. H. Torsion stability achieved. When the hooks are coupled to vertically spaced portions of one or more railing elements, torsional stability relative to a horizontal axis, i. H. Tilting stability, 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 element 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 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 fixing 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 offset of the horizontal profiles, so that the hooks are preferably suspended immediately adjacent to the vertical support when coupled with a railing element on two pointing in opposite directions horizontal profiles.

Preferably, the railing element in addition to the areas provided for the hook on a contact surface for supporting the shuttering element below the hook.

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:

1a to 1c Side views of a clamping device of a supporting device according to the invention,

1d and 1e perspective views of two corner mounted clamping devices of a supporting device according to the invention,

2 to 7 perspective views of a formwork system according to the invention in various assembly states,

8th a side view of a variant of a railing element for mounting to a support device according to the invention, and

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

A carrying device according to the invention comprises according to 1a to 1e a clamping device 12 which two vertically extending, spaced-apart base body 14 comprises, at their 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 1a to 1c only one visible at a time. As in particular in 1d . 1e and 3 it can be seen, are the two main body 14 or lower cantilever beam 16 over footbridges 38 connected with each other.

Between the basic bodies 14 is a vertically adjustable (see double arrow in 1a ) and pivotable about a horizontal axis (see double arrow in 1b ) upper cantilever 18 arranged. The basic body 14 For this purpose, several vertically spaced, horizontal holes 20 for receiving safety bolts 22 for fixing the upper cantilever 18 in the respective desired vertical position. Two different vertical positions are in the 1a and 1b once with solid lines and once shown with dashed lines. The safety bolts 22 can through these holes 20 and by also vertically spaced, horizontal holes 20 of the upper cantilever 18 be passed.

If both safety bolts 22 through the holes 20 in the upper cantilever 18 passed through, this is verschwenksicher to the bodies 14 fixed ( 1a ). At the in 1b shown adjustment position is the lower safety bolt 22 out of the hole 20 of the upper cantilever 18 pulled out. After the upper cantilever 18 has been pivoted slightly upward, which is indicated by the double arrow, is the pulled out lower safety bolt 22 back in one of the holes 20 the main body 14 been inserted, so that this now a stop for the upwardly pivoted upper Kragträger 18 Form and adjust it in the pivoted position 1b holds. The associated increase in the distance between the upper Kragträger 18 and the lower cantilevers 16 facilitates the assembly of the clamping device 12 on an existing building ceiling.

At the free end of the upper cantilever 18 is a tensioning device 24 provided, which is shown in the embodiment as a spindle. In principle, however, other, preferably self-locking adjusting means can be used. The lower end portion of the tensioning device 24 has a circulation 25 for the top of the building ceiling.

At the lower cantilevers 16 opposite side of the main body 14 is a coupling sleeve 26 for receiving a vertical support 34 (please refer 1c ) arranged. The coupling sleeve 26 is by means not shown adjusting means with respect to the main body 14 vertically adjustable in height. The vertical beam 34 is as well as the coupling sleeve 26 with holes 20a respectively. 20b for safety bolts 22 provided for mutual locking. Between the vertical support 34 and the coupling sleeve 26 There is a certain play, so that the vertical support 34 by a small amount to that in the coupling sleeve 26 locked safety bolts 22 can be pivoted. The coupling sleeve 26 has a bottom in the embodiment, 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 of the body 14 is a frame-shaped support element 28 fastened, in which a guide sleeve 30 horizontally in the main extension direction of the cantilevers 16 . 18 slidably received. For horizontal adjustment of the guide sleeve 30 is one between the guide sleeve 30 and the basic bodies 14 effective spindle 32 intended.

With reference now to 1c be the various adjustment options, the clamping device 12 are provided, explained again. Within the circle A, a double arrow F is shown, which shows the vertical adjustment of the clamping device 24 or of the upper cantilever 18 suggests.

First, a coarse adjustment of the distance between the Kragträgern 16 . 18 by selecting a suitable hole pair 20 in the main body 14 , in which the safety bolts 22 be plugged in.

To reach the in 1c shown mounting position is the clamping device 12 then first with the top cantilever pivoted upwards 16 ( 1b ) on the existing building ceiling 36 ( 1c ) postponed or "threaded". This relative movement between the building ceiling 36 and the clamping device 12 is in 1c indicated by the arrow in the mark B.

Subsequently, the upper Kragträger 18 in the working position 1c pivoted downwards and with a second (lower) safety pin 22 fixed.

Then the tensioning device 24 pressed, so that the circulation 25 moved down in the direction of arrow F and the building ceiling 36 between the lower cantilevers 16 and the edition 25 is clamped. The through the two lower cantilevers 16 defined, sufficiently dimensioned surface ensures a reliable fixation of the clamping device 12 at the bottom of the building ceiling 36 , causing a tilting of the clamping device 12 is excluded by a horizontal axis.

The double arrow bounded by the mark C symbolizes the subsequently possible vertical adjustment of the vertical support 34 above 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 shows the still possible tilt adjustment of the vertical support 34 in relation to the on the building ceiling 36 fixed body 14 by means of the spindle 32 at. The importance of this adjustment of the vertical support 34 will be explained below.

1d and 1e show an arrangement of two largely formed in the manner described above clamping devices 12 . 12 ' for an over-corner attachment to an outside corner of the building ceiling 36 in which, due to space constraints or for static reasons, the lower cantilevers 16 . 16 have to overlap. 1d shows the at the building ceiling 36 mounted arrangement obliquely seen from below with a view towards the underside of the building ceiling 36 while in 1e the arrangement is shown without the building ceiling obliquely seen from above.

For this purpose, the lower cantilevers 16 ' the one clamping device 12 ' at its top with two spacers 39 Mistake. The spacers 39 have a T-shaped configuration, wherein the transverse bar of a T performing portion on the two cantilevers 16 ' rests and a the foot of a T performing section between the Kragträger 16 ' protrudes into and the Kragträger 16 ' connecting webs 38 is fastened for example by means of screwing.

The crossbar of a T performing section is at least as strong as the Kragträger 16 the other clamping device 12 so that the support base of the cantilevers 16 at the bottom of the building ceiling 36 in an outside corner mounting according to 1d in comparison to an exclusive edition of the cantilevers 16 is increased accordingly in a mounting without spacers and that of the two spacers 39 spanned surface corresponds.

With reference now to the 2 to 7 the structure of a formwork system according to the invention will be explained in more detail.

On an existing building ceiling 36 , on the already pillars 40 were built as a support for a new building ceiling to be created, several clamping devices 12 , Vertical beam 34 and further to be described railing elements 42 and formwork elements 44 provided ( 2 ). In each case a clamping device 12 and a vertical beam 34 become a carrying device 10 ( 3 ) joined together.

As in 3 is clearly visible, is at an upper end portion of the vertical support 34 a railing element 42 attached. In order to enable at least a large-scale adaptation to the desired floor height of the new building ceiling to be created, both the upper end of the vertical support 34 as well as a vertical profile 46 the railing element 42 with a plurality of vertically spaced holes 20 Mistake. The attachment takes place by means of unrecognizable security bolts, which through the holes 20 the two parts to be joined 34 . 46 be put through.

Several vertically spaced horizontal profiles 48 are with their one end on the vertical profile 46 attached. 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 points in the opposite direction so that the horizontal profiles 48 on both sides of the vertical profile 46 each offset from one another.

On the pre-assembled carrying device 10 becomes a carrying rope or a carrying chain in the area above its center of gravity 50 a lifting device attached to the carrying device 10 in a mounting position according to 4 (see upper support 10 ) to transport. For attaching the carrying chain 50 on the vertical support 34 is one with an eyelet for hanging the carrying chain 50 provided fastener 51 provided, which by means of a safety pin 22 located in one above the center of gravity of the support device 10 in the vertical beam 34 introduced further drilling 20a is recorded on the vertical support 34 is fixed ( 3 ). The carrying device 10 is in the manner described above on the existing building ceiling 36 tightened.

These steps are repeated until the building ceiling 36 along their respective desired peripheral area with supporting devices 10 is provided ( 5 ). It is possible, two or more support devices 10 z. B. by diagonal struts (not shown) to a unit and couple these coupled support devices 10 to assemble together and / or implement from one building ceiling to the next, thereby reducing the time required for assembly or implementation reduced.

In 5 is good to see that the railing elements 42 already provide a complete fall protection for work on a slab formwork still to be created. In particular, it is easy to see how the horizontal profiles 48 a railing element 42 yourself between the horizontal profiles 48 an adjacent railing element 42 extend without it being an adaptation of the railing elements 42 depending on the distance between adjacent support devices 10 requirement. As a result, it is not necessary in the attachment of the support devices 10 on the building ceiling 36 to pay attention to a precise adherence to a given grid size. Only one by the width of the railing elements 42 given maximum distance is to be considered.

Alternatively, instead of the railing elements 42 also railing elements 42 ' according to 8th are used, in which, in contrast to the railing element 42 ( 2 to 7 ) Each two pointing in opposite directions horizontal profiles 48 offset from each other opposite each other on the vertical profile 46 are arranged. 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 becomes the desired entanglement of the horizontal profiles 48 adjacent railing elements achieved in that the mounting positions of adjacent railing elements at their respective vertical beams 34 slightly offset from each other in the vertical direction, this offset preferably about half the vertical distance of the horizontal profiles 48 may amount to each other.

Especially when considering the outer and inner corner areas ( 5 ) it becomes clear that building ceilings 36 create any dimensions and secure with both handrail element variants, without that specially adapted handrail elements 42 requires, as the horizontal profiles 48 adjacent railing elements 42 both when arranged on a longitudinal side of a building ceiling 36 as well as in 5 shown outer corner (see arrows A) and inner corner assemblies (see arrow B) can be interlocked with each other at an angle over a wide distance range easily.

To increase the stability of the guardrail can be between individual horizontal profiles 48 adjacent railing elements 42 additional coupling means are provided. However, this is due to the torsional stiffness of the vertical beam 34 and the flexural rigidity of the horizontal profiles 48 not mandatory.

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

In the in 5 illustrated embodiment includes a formwork element 44 three formwork panels each 54 , which by means of several continuous, on the back of the formwork panels 54 arranged coupling profiles 56 are rigidly coupled together. In principle, the use of formwork elements with a different number of formwork panels 54 possible. For example, a formwork element with only one formwork panel 54 be used.

Also on the back of each board 54 are hooks 52a . 52b provided which have a vertical offset against each other, the offset of the opposite sides of the vertical profile 46 fixed horizontal profiles 48 equivalent.

So that the guardrail has a sufficient effective height, the formwork elements 44 preferably in the respective lowest horizontal profiles 48 hooked. One on the vertical profile 46 intended contact surface 60 ensures reliable vertical alignment of the formwork elements 44 (see also 3 and 8th ).

After all formwork elements 44 in the corresponding railing elements 42 can be hung according to the 6 and 7 a supporting structure 62 be erected for a slab formwork. On this support structure 62 can now formwork floor elements 64 be attached. To support the formwork floor elements 64 to ensure even in the edge area, are the formwork panels 54 on its front with a support 58 for the formwork floor elements 64 Mistake.

Out 6 It can be seen that by means of the vertical and tilt adjustment of the vertical support 34 an exact and fine adjustment or leveling of the formwork elements 44 in relation to the height and lateral dimensions of the new building ceiling.

Finally, the formwork created in this way with concrete 66 be replenished ( 7 ), which forms the newly created building ceiling after curing. To avoid being affected by the load of the concrete 66 individual formwork elements 44 pushed outward, allows the tilt adjustment of the vertical support 34 an additional bias on the formwork elements 44 exercise, so that the predetermined dimensions for the new building ceiling can be met.

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

The other end of the carrying chain 50 gets into an adjustable clamping element 68 hung, which in turn in a on the building ceiling 36 attached coupling element 70 is mounted. By pressing the clamping element 68 is about the carrying chain 50 a tensile force on the vertical beam 34 exercised and the carrying device 10 pretensioned 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.
