Detailed description of preferred embodiments of the invention

In Fig. 1 the formwork table according to the invention is 10 denotes and forms together with on the underside attached supports 24, attached to the top Connecting elements 14, attached to this Formwork beams 18 and numerous placed thereon Concrete formwork panels 20 an arrangement for forming a horizontal formwork level for concreting a ceiling. In practice are used to concreting a ceiling with larger ones Dimensions of many of the arrangements shown side by side erected and thus form a continuous formwork level. The arrangement shown, the combination according to the invention is subsequently described in detail in a direction of explained below up. In the case shown, the Schalisch 10 four support elements 32 on their Bottom not, as was previously the case, for the Are set up on level ground, but for the attachment of a support 24 with its top are trained. The supports 24 are on their underside each by means of a suitable foot plate 34 for installation trained on level ground. The supports can be commercially available length-adjustable supports made of steel or Aluminum, for example act according to DIN EN 1065. Through peg holes 36 in the lower, as an inner tube provided tube of the support 24, and by a Pin 38 and one on a thread of the top, as Outer pipe provided pipe 40 located the nut Experts who are all known will be a big one The length of the support can be adjusted.

The support 24 has one on its upper side Head plate 26, for example in the standard mentioned is described. Furthermore, the support is in this area usually with an opening for a centering mandrel Mistake. To fast and reliable attachment of the respective support 24 on the support member 32 of the To ensure formwork 10, the support member 32nd on the bottom with one in the drawing Provide centering mandrel that cannot be recognized. This Centering mandrel defines the position of the support 24 with respect to the Bottom of the support member 32 in all horizontal Directions. This is essentially supported by two L-shaped collars 42 that extend from the footplate to the Extend bottom of the support member 32. If the prop 24 with its head plate 26 in the direction of its axial Extension into the centering mandrel of the support element 32 was introduced in the case shown by suitable Openings in the collars 42 hammered a double wedge 44 and thereby fix the support 24 over its head plate also in the vertical direction.

The measures described above for fixing the Support 24 on its top are associated with the present invention as second attachment elements 22 designated. As at the top of the formwork table 10 too can be seen, the connecting elements 14, the Connection between the formwork beams 18 and the top of the formwork table 10 serve, also such, second Attachment elements 22. As mentioned, these are for the Connection with supports 24 adjusted over the top plates and well known to those skilled in the art. In this respect, the Details described in connection with the in Fig. 1st illustrated embodiment to explain the invention suffice. According to the invention it is important that the sound table 10 according to the invention on its underside each through the formation of the second attachment elements 22 such is designed that here in a previously unknown manner and Ways supports 24 are attachable.

The formwork table 10 itself has in the shown case four support members 32 by two Cross 46 and a diagonal strut 48 to one two-dimensional structure, a so-called frame 28 connected are. The formwork table 10 shown has two such frames which are connected to one another by diagonal struts 30, so that a stable, three-dimensional structure is created. The Struts 30 can be detachable, so that the frame 28 at a special embodiment with respect to its top the arrangement consisting of connecting elements 14, Formwork beams 18 and concrete formwork panels 20 swivel are. This is discussed in more detail below with reference to the further figures explained. It should be mentioned that the Formwork table 10 with regard to the support elements 32 and Struts 30, 46 and 48 can also be designed so that four individual support elements 32 on all four sides Diagonal struts 30 are connected. In other words in this case not two, as shown in FIG. 1 Support elements 32 through the struts 46 and 48 into one Frame 28 connected. Rather, it would be three-dimensional stable formwork table 10 by four support elements 32 and several, preferably a total of eight, diagonal struts 30 educated.

At the top of the respective support element 32 is over Attachment elements that correspond to the so-called second attachment elements 22 correspond, each have a connecting element 14 attached. In particular, the support elements 32 have on their top one head plate and one opening for one Centering mandrel on how they are used for the tops of Supports are known. Over extending upwards Leg 16 of the connecting elements 14 are shown in the Case close to the respective connecting element 14 two Formwork beams arranged to each other in a first Direction, the so-called longitudinal direction, can be attached. On the are a total of four formwork beams 18 in the longitudinal direction numerous formwork beams 18 in one direction perpendicular for this, the so-called transverse direction. To this Formwork beams are in turn several concrete formwork panels hung up.

Overall, this creates an arrangement, on the one hand due to the extensive adjustability of the individual Supports 24 in an extremely advantageous manner Has flexibility in height adjustment. Furthermore, the Combination overall inexpensive, because in the lower area the inexpensive supports used as standard components can be, and no struts 30, 46, 48, as for the Schalisch 10 recognizable, are required. Furthermore is due to the lack of these struts a free passage in the guaranteed lower area. Both the supports 24 can on the formwork table 10, as well as the frame 28 of the formwork table 10 can be pivotally attached to the formwork beams 18 his.

A suitable connecting element in the form of a so-called. Swivel head 52 is shown in FIGS. 2 and 3. The swivel head 52 forms a certain element between the Head plate 26 of the support 24 or the support element 32 of the Formwork table and the underside of the support element 32 of the Formwork table 10 or the connecting element 14 to attach is. For this purpose, the swivel head 52 has on it Bottom of a centering pin 54, in one appropriate opening in the head plate 26 is to be introduced. The swivel head 52 is also provided with collars on its underside 42 corresponding to those shown in Fig. 1, in which Openings are formed, into which parts 44 are hammered can be. 2 is a Head plate fixed above the wedges 44 shown. At his The swivel head has a top plate 56 with an upper side Opening 58 for a centering mandrel. Thus the Swivel head 52 on its top according to the standardized Supports 24 designed and can accordingly Bottom of the support member 32 of the formwork table 10 or the underside of the connecting element 14 are attached. This can either be at the bottom of the Swivel head 52 attached support 24 pivotally on the Formwork table 10 are attached. Alternatively, it can respective support member 32 pivotable on the Connection element 14 are attached.

As can be seen in Fig. 2, the fixation takes place in the not pivoted position by a suitable pawl 60, which is articulated on the upper part of the swivel head 52. By a suitable hook contour 62 is engaged with pin 64 formed on the lower part. When the pawl 2 pivoted to the top right as shown in FIG this intervention is released and the lower part of the Swivel head 52 can be pivoted about the pivot point 66 become.

The pivoted-out position is shown in Fig. 3. In this Position can be fixed in the swiveled position take place by a second hook contour 66 on the pawl 60, the one shown in another case is provided as the first hook contour 62, with a further pins 68 on the lower part of the swivel head 52 in Intervention comes. As is readily apparent from FIG. 3 is conceivable, the arrangement above the Swivel head 52 still in the position shown in FIG. 2 are located on the lower part of the swivel head 52 support no longer vertically down, but instead extends diagonally down to the left. This allows the Overall arrangement lowered and for example by lower passages are moved through. foregoing a case has also been described that such Swivel head between the respective support element 32 and the Connecting element 14 is provided so that the frame 28 of the formwork table 10 with respect to the formwork beams are pivotable after the struts 30 have been released.

In Fig. 4 a case is additionally shown that the Supports 24 are pivotally attached to the formwork table 10. The design of the so-called swivel head 52 varies somewhat from that shown in Figs. 2 and 3, however, does the same Functions. The remaining elements of that shown in FIG. 4 Combination correspond to those according to Fig. 1. Regarding the connection between the top of the formwork table 10 and the formwork girders 18 are also with regard to FIG. 1 still mentioned that the intermediary here Fasteners 14 are not absolutely necessary. Rather, the respective support elements 32 of the Schalisches 10 on its top also directly for the Connection with formwork girders.
