[0039] FIG. 8 shows a top view of a further ceiling formwork;

[0040] FIG. 9 shows a perspective view of a dual support; and

[0041] FIG. 10 shows top views of various possible applications of the formwork parts according to the invention.

[0042] FIG. 1 shows a ceiling formwork 10. The ceiling formwork 10 is used to produce a concrete ceiling, which is supported on the walls 12a, 12b. The ceiling formwork 10 has multiple formwork elements, of which only one formwork element 14 is provided with a reference numeral for reasons of clarity. The formwork elements 14 are supported on ceiling supports, of which only one ceiling support 16 is likewise provided with a reference numeral in FIG. 1 for reasons of clarity. The ceiling support 16 has a formwork support 18 and a support head 20 situated thereon. The formwork elements 14 have a frame 22 with a formwork shell 24 situated thereon. The formwork elements 14 have a rectangular design, so that ceilings having arbitrary shapes are producible without using solely the formwork elements 14 illustrated in FIG. 1.

[0043] The ceiling formwork 10 therefore has formwork parts 26a-c. The formwork parts 26a-c, the same as the formwork elements 14, are supported by ceiling supports 16. In addition, the formwork parts 26a-c, the same as the formwork elements 14, are suspendable at one end in at least one support head 20, and may then be swiveled up from below. This is apparent in FIG. 1 with reference to the formwork part 26a. After the swiveling up, the formwork parts 26a-c may be supported on the swiveled-up end by at least one further ceiling support 16.

[0044] FIG. 2 shows a base frame 28 of a formwork part 26a-c (see FIG. 1). The base frame 28 has a first transverse support 30a, a second transverse support 30b, and a longitudinal support 32. The longitudinal support 32 connects the transverse supports 30a, 30b. The connection of the transverse supports 30a, 30b is strengthened by a longitudinal connector 34. The longitudinal connector 34 is fixedly connected to the transverse supports 30a, 30b, opposite from the longitudinal support 32.

[0045] FIG. 3 shows an outer support 36. The outer support 36 has outer support guide strips 38a-d.

[0046] FIG. 4 shows the formwork part 26c according to FIG. 1. The outer support 36 (see FIG. 3) is situated on the base frame 28 (see FIG. 2). The outer support 36 with its outer support guide strips 38a-d (see FIG. 3) engages behind transverse support guide strips 40a-d. In the present exemplary embodiment, the outer support 36 is displaceably guided in the direction of the longitudinal axes 42a, 42b. In the present case, the outer support 36 is also displaceable in parallel alignment with the longitudinal support 32. In other words, the longitudinal axis 44 of the outer support 36 extends in parallel to the longitudinal axis 46 of the longitudinal support 32. At least one stop 48a, 48b prevents the outer support 36 from slipping out and falling off the transverse supports 30a, 30b. Each transverse support 30a, 30b preferably has at least one stop 48a, 48b.

[0047] FIG. 5 shows a center support 50a. The center support 50a is preferably virtually identical to the outer support 36 (see FIG. 3). However, the center support 50a has only two center support guide strips 52a, 52b. In addition, the center support 50a has movably guided pins 54a, 54b.

[0048] FIG. 6 shows the formwork part 26a (see also FIG. 1). It is apparent from FIG. 6 that the transverse supports 30a, 30b of the formwork part 26a have pegging openings into which the pins 54a, 54b (see FIG. 5) are partially insertable. Only two pegging openings 56a, 56b are provided with a reference numeral in FIG. 6 for reasons of clarity. When the center support guide strips 52a, 52b (see FIG. 5) engage behind the transverse support guide strips 40a, 40c (see FIG. 4) and the pins 54a, 54b (see FIG. 5) are partially inserted into the pegging openings 56a, 56b, the center supports 50a, 50b are fixedly connected to the transverse supports 30a, 30b. In contrast, by loosening the pins 54a, 54b (see FIG. 5), the center supports 50a, 50b may be either moved in parallel in the direction of the longitudinal axes 42a, 42b, or removed from the transverse supports 30a, 30b without removing the longitudinal support 32 and/or the outer support 36 from the transverse supports 30a, 30b.

[0049] It is apparent from FIG. 6 that the longitudinal support 32, the center supports 50a, 50b, and the outer support 36 have a nail strip 58a-d, respectively. The nail strips 58a-d are preferably made of plastic or wood. They are used to fasten a customized-to-fit compensation element formwork shell (not shown).

[0050] The longitudinal support 32, the center supports 50a, 50b, and the outer support 36 at their respective lengthwise ends have support head receptacles in the form of connecting protrusions 60a-k, of which only some are provided with a reference numeral in FIG. 6 for reasons of clarity. The connecting protrusions 60a-k are preferably provided on sheet metal strips. The connecting protrusions 60a-k are designed to partially engage behind support heads 20 (see FIG. 1).

[0051] FIG. 7 shows a ceiling formwork 10 together with the formwork element 14 and the formwork parts 26b, 26c. The formwork element 14 has a width A perpendicular to its longitudinal axis and parallel to its formwork shell 24 (see FIG. 1). The formwork part 26b has a width B perpendicular to its longitudinal axis and parallel to a plane in which the transverse supports 30a, 30b extend (see FIG. 6), corresponding to the maximum span width of the formwork part 26b. The formwork part 26c has a width C perpendicular to its longitudinal axis and parallel to a plane in which the transverse supports 30a, 30b extend (see FIG. 6), corresponding to the minimum span width of the formwork part 26c. The width A corresponds, at most, to the difference between the widths B and C. Any given distances between the formwork element 14 and the wall 12b are achievable: If the distance of the formwork element 14 from the wall 12b exceeds the maximum span width of the formwork part 26c, a further formwork element 14 may be inserted. On the other hand, if the distance of the formwork element 14 from the wall 12b is less than the minimum span width of the formwork part 26c, the formwork element 14 may be removed, and, in its place, a formwork part 26c may be inserted which has a span width greater than the width A of the formwork element and less than the maximum span width B of the formwork part 26c. The transverse supports 30a, 30b of the formwork part 26c may partially engage beneath the formwork element 14.

[0052] FIG. 8 shows a ceiling formwork 10 in which the formwork parts 26a-c are used in the case of a wall 12b that runs at an angle with respect to the wall 12a.

[0053] FIG. 9 shows a dual support 62. The dual support 62, the same as the center support 50a (see FIG. 5), may be individually inserted between formwork elements 14 to allow narrow distances between formwork elements 14 to be provided with a compensation element formwork shell (not shown).

[0054] FIG. 10 shows multiple ceiling formworks 10, which indicate by way of example various possible applications of formwork elements 14, formwork parts 26a-c, dual supports 62, and center supports 50a. Only some of these elements are provided with a reference numeral for reasons of clarity. It is apparent that dual supports 62 may also be supported on transverse supports 30a, 30b.

[0055] Considered in an overview of all figures of the drawing, the invention in summary relates to a formwork part 26a-c having a compensation element. The compensation element has a longitudinal support 32, and two transverse supports 30a, 30b that are connected to the longitudinal support 32. An outer support 36 is displaceably situated on the transverse supports 30a, 30b. In addition, at least one center support 50a, 50b may be fastened to the transverse supports 30a, 30b so as to be detachably removable from the transverse supports 30a, 30b. The longitudinal support 32, the outer support 36, and/or at least one center support 50a, 50b preferably have/has at least one support head receptacle at both ends, in particular in the form of a connecting protrusion 60a-k, in particular at least two support head receptacles, preferably in the form of connecting protrusions 60a-k. The connecting protrusions 60a-k may be hooked into ceiling supports 16 of the ceiling formwork 10. The invention further relates to a ceiling formwork 10 comprising such a formwork part 26a-c and a formwork element 14. The formwork element 14 preferably has at least one support head receptacle, in particular in the form of a connecting protrusion 60a-k, that may be hooked into the ceiling support 16 of the ceiling formwork 10. The ceiling formwork 10 may include the ceiling support 16. The ceiling formwork 10 may have a dual support 62.
