The ceiling table (10) has at least one formwork element, in particular multiple formwork elements, which can be assembled on a lower frame (16) of the ceiling table (10) in a nondestructive manner and which can be disassembled from the lower frame (16). The ceiling table (10) has a support skeleton (14) on which at least one formwork element, in particular multiple formwork elements, is/are arranged. The support skeleton (14) can have multiple braces which can be connected together and separated from one another in a nondestructive manner. The support skeleton preferably has a pair of main supports, in particular parallel running main supports, on which a pair of edge supports and at least one central support that is arranged between the edge supports are arranged. The edge supports and the central support run preferably parallel to one another. The invention further relates to a ceiling formwork comprising such a ceiling table (10).

[0038] FIG. 13 a perspective view of two ceiling tables according to FIG. 12.
[0039] FIG. 1 shows a ceiling table 10 comprising multiple formwork elements of which only formwork elements 12a-c are provided with a reference character for the sake of clarity. Formwork elements 12a-c are arranged on a support skeleton 14 of ceiling table 10 in such a way that they can be removed without being destroyed. Support skeleton 14 is arranged on a lower frame 16 comprising multiple supports of which only supports 18a-c are provided with a reference character for the sake of clarity. Support skeleton 14 is arranged on lower frame 16 in a reversibly detachable manner. Individual parts of support skeleton 14 are explained below.
[0040] FIG. 2 shows a first main support 20a of support skeleton 14 (see FIG. 1) comprising attachment points 22a-c for lower frame 16 (see FIG. 1).
[0041] FIG. 3 shows a first edge support 24a of support skeleton 14 (see FIG. 1). First edge support 24a has attachment points 22d, 22e for mounting first edge support 24a to first main support 20a in a reversibly detachable manner (see FIGS. 2 and 4).
[0042] FIG. 4 shows a support skeleton 14 comprising a first edge support 24a and a second edge support 24b. Edge supports 24a, 24b are arranged on first main support 20a and a second main support 20b in a reversibly detachable manner.
[0043] FIG. 5 shows a first central support 26a of support skeleton 14 (see FIG. 1). First central support 26a has attachment points 22f, 22g. Attachment points 22f, 22g of first central support 26a are designed identical to attachment points 22d, 22e (see FIG. 3) of first edge support 24a. First central support 26a can, as a result, be arranged on main supports 20a, 20b (see FIG. 4) in a simple mannerjust like first edge support 24a.
[0044] FIG. 6 shows a support skeleton 14 comprising multiple main supports 20a, 20b as well as edge supports 24a, 24b and central supports 26a-e arranged on main supports 20a, 20b in a reversibly detachable manner. Longitudinal axes 28a, 28b of main supports 20a, 20b run parallel to each other. Longitudinal axes 30a, 30b of edge supports 24a, 24b run offset and perpendicular to longitudinal axes 28a, 28b of main supports 20a, 20b. Furthermore, longitudinal axes 32a-e of central supports 26a-e run offset and parallel to longitudinal axes 28a, 28b of main supports 20a, 20b. As a result, support skeleton 14 forms receiving frame that can be expanded and reduced in size flexibly for multiple rectangular formwork elements 12a-c (see FIGS. 7 and 8).
[0045] FIG. 7 shows first formwork element 12a (see also FIG. 1). First formwork element 12a has a formwork element frame 34. Formwork element frame 34 preferably has at least one carrying aperture 36a-d. A formwork shell 38 is arranged on formwork element frame 34. Formwork element frame 34 is made from metal, in particular from steel or aluminum. To manufacture formwork element frame 34 in a simplified manner and easily repair damage to a corner of first formwork element 12a, first formwork element 12a has plastic cladding 42a-c on its corners 40a-d, only plastic cladding 42a-c of corners 40-ac being visible in FIG. 7 due to the perspective representation of first formwork element 12a.
[0046] FIG. 8 shows support skeleton 14 according to FIG. 6 with formwork elements 12a-c arranged thereon (see also FIG. 7). Formwork elements 12a-c are identical in design. In each case, two formwork elements 12a-c can be arranged between two central supports 26a-e or between an edge support 24a, 24b and the central support 26a, 26e nearest to edge support 24a, 24b. Formwork elements 12a-c can be mounted to support skeleton 14 and removed from support skeleton 14 independently of one another.
[0047] FIG. 9 shows support skeleton 14 according to FIG. 8 with all formwork elements 12a-l that can be attached to support skeleton 14. Formwork elements 12a-l can optionally be inserted between central supports 26a-e or between central supports 26a, 26e and edge supports 24a, 24b nearest to them. The locking of formwork elements 12a-l is done via end stops 44a-e of central supports 26a-e that are releasably screwed on, of which only the end stops 44a-e arranged on central supports 26a-e at one end are visible in FIG. 9 (see also FIG. 6 with respect to the end stops arranged at the other end). End stops 44a-e are preferably plate-shaped.
[0048] FIG. 10 shows a ceiling formwork 46 comprising ceiling table 10. According to the illustration in FIG. 10, further formwork elements 48a-c can be added onto ceiling table 10. Other formwork elements 48a-c are connected to ceiling table 10 via support heads, only the support heads 50a, 50b used for attachment to ceiling table 10 being visible in FIG. 10 due to the perspective representation. Support heads 50a, 50b connect formwork elements 12g, 12k to other formwork elements 48a, 48b.
[0049] Formwork elements 12a-l are identical in design to other formwork elements 48a-c. Both formwork elements 12a-l and other formwork elements 48a-c have coupling points (see coupling points 56a-d according to FIG. 11) for the connection of a support head 50a, 50b. Support heads 50a, 50b are arranged on formwork supports 52a, 52b. Support heads 50a, 50b form ceiling supports 54a, 54b together with formwork supports 52a, 52b.
[0050] FIG. 11 shows by way of example further formwork element 48c to illustrate the flexible connectability of further formwork elements 48a-c (see FIG. 10) to formwork elements 12a-l (see FIG. 10). In FIG. 11, formwork shell 38 (see FIG. 7) is not visible. It can be seen from FIG. 11 that the further formwork element 48c has coupling points 56a-d in the area of its corners 40a-d. As shown by way of example with reference to coupling point 56a, coupling points 56a-d preferably have locking projections 58a-c. Coupling points 56a-d provide the possibility of a corner connection of a support head 50c-f. It can be seen from FIG. 11 that support heads 50c-f can be mounted on further formwork element 48c with various degrees of engagement such that respective support head 50c-f can support different numbers of other formwork elements (not shown in FIG. 11).
[0051] Further formwork element 48c has middle coupling points 60a, 60b to make central support of further formwork element 48c possible via support heads 50g, 50h.
[0052] Support heads 50a-h (see also FIG. 10) of ceiling formwork 46 (see FIG. 10) are preferably identical in design.
[0053] FIG. 12 shows a ceiling table 10. Ceiling table 10 corresponds to ceiling table 10 according to FIG. 1. However, formwork element 12j (see FIGS. 9 and 10) was not mounted. As a result of this, ceiling table 10 can be used at the construction site despite a concrete column 62.
[0054] FIG. 13 shows a ceiling formwork 46 in which two ceiling tables 10 are fitted together according to FIG. 12 to frame concrete column 62.
[0055] When viewing all figures of the drawing together, the invention relates, in summary, to a ceiling table 10 for the partial formwork of a concrete ceiling. Ceiling table 10 has at least one formwork element 12a-l, in particular multiple formwork elements 12a-l, that can be assembled on a lower frame 16 of ceiling table 10 in a nondestructive manner and can be disassembled from lower frame 16. Ceiling table 10 has a support skeleton 14 on which at least one formwork element 12a-l, in particular multiple formwork elements 12a-l, is/are arranged. Support skeleton 14 can have multiple struts that can be connected together and separated from one another in a nondestructive manner. The support skeleton preferably has a pair of main supports 20a, 20b, in particular parallel running main supports, on which a pair of edge supports 24a, 24b and at least one central support 26a-e that is arranged between the edge supports 24a, 24b are arranged. Edge supports 24a, 24b and central support 26a-e preferably run parallel to each other. The invention further relates to a ceiling formwork 46 comprising such a ceiling table 10.
