DETAILED DESCRIPTION

[0026] In the figures, functionally identical elements are provided with the same reference signs.

[0027] FIG. 1 shows an assembly and shifting trolley 1 for use in a method according to the invention for assembling or dismantling at least one slab table 2 (see FIGS. 9 and 10) for at least partial formworking of a concrete slab (not shown). The shifting trolley 1 has a raisable and lowerable receiving device 3 which is designed to receive a first main girder 4a and a second main girder 4b of a carrier skeleton 5, shown in FIGS. 2 through 10, of a slab table 2. The shifting trolley 1 can be provided with at least one winch 6, via which the receiving device 3 can be raised and lowered. Furthermore, the receiving device 3 has holding regions 3a which are adapted to a cross-sectional shape of the main girders 4a, 4b. As can be further seen from FIG. 1, the shifting trolley 1 is provided with rollers 1a for movement. The main girders 4a, 4b are provided with receptacles 12 for at least one support 10.

[0028] In addition, edge girders 7 and central girders 8 for the carrier skeleton 5 are shown in FIG. 1. In addition, a stack having formwork elements 9 is present. To complete the slab table 2, the at least one support 10 is required, which is shown in FIGS. 9 and 10.

[0029] According to the invention, a method for assembling at least one slab table 2 for at least partial formworking of a concrete slab is proposed, which has a carrier skeleton 5, at least one formwork element 9, and at least one support 10, wherein the method comprises, in sequence, at least the following steps indicated in FIGS. 1 through 10.

[0030] In FIG. 1, in a step a), the—in particular, movable—shifting trolley 1 is provided with the raisable and lowerable receiving device 3, which is designed to receive the carrier skeleton 5 of the slab table 2.

[0031] FIGS. 2 through 5 show, as step b), mounting of the carrier skeleton 5 of the slab table 2 on the receiving device 3 of the shifting trolley 1. In this case, in a substep b1) of step b), as shown in more detail in FIG. 2, the first main girder 4a and the second main girder 4b spaced apart therefrom are arranged in the receiving device 3 of the shifting trolley 1, wherein the longitudinal axis of the first main girder 4a runs parallel to the longitudinal axis of the second main girder 4b. FIG. 3 shows a substep b2) of step b), in which first and second edge girders 7 are reversibly detachably fastened to the main girders 4a, 4b, wherein the longitudinal axes of the edge girders 7 run perpendicular to the longitudinal axes of the main girders 4a, 4b.

[0032] FIGS. 4 and 5 show, as substep b3) of step b), reversibly detachably fastening the at least one central girder 8 to the main girders 4a, 4b, wherein the longitudinal axis of the central girder 8 runs parallel to the longitudinal axes of the edge girders 7.

[0033] FIGS. 6 and 7 show a step c), in which the at least one formwork element 9 is fastened to the carrier skeleton 5 of the slab table 2. The at least one formwork element 9 has a formwork skin 9a, which is arranged on a formwork element frame 9b.

[0034] As shown in FIG. 8, in a step d), the carrier skeleton 5 is raised together with the at least one formwork element 9.

[0035] Mounting of the at least one support 10 on an underside 11, which faces away from the at least one formwork element 9, of the carrier skeleton 5 of the slab table 2 according to a step e) is shown in FIG. 9. For this purpose, the supports 10 can be introduced into the receptacles 12 of the main girders 4a, 4b.

[0036] In a step f), the shifting trolley 1 is positioned and aligned at the intended mounting location of the slab table 2. In a step g), the slab table 2 is positioned at the installation height by means of the raisable and lowerable receiving device 3 of the shifting trolley 1. Finally, in a step h), the at least one support 10 is adjusted in order to place the slab table 2 on the at least one support 10. Steps f), g), and h) are indicated in FIG. 9.

[0037] As can be seen from FIG. 10, in a step i), the receiving device 3 is lowered, and the shifting trolley 1 is removed.

[0038] The dismantling of the at least one slab table 2 takes place in the reverse sequence, as it were, by means of the following method steps:

a) providing the—in particular, movable—shifting trolley 1 with the raisable and lowerable receiving device 3, which is designed to receive the carrier skeleton 5 of the slab table 2;
b) positioning and aligning the shifting trolley at the installation location of the slab table 2 to be dismantled;
c) positioning the raisable and lowerable receiving device 3 at the mounting height of the slab table 2, and receiving the carrier skeleton 5 of the slab table 2 in the receiving device 3 of the shifting trolley 1;
d) dismantling the at least one support 10;
e) lowering the carrier skeleton 5, provided with the at least one formwork element 9, of the slab table 2 to a working height;
f) dismantling the at least one formwork element 9;
g) dismantling the carrier skeleton 5 of the slab table 2, wherein central girders 8, edge girders 7, and the main girders 4a, 4b are dismantled; and
h) removing the shifting trolley 1.
