The invention relates to a scaffolding system with at least one scaffold decking (30). The scaffold deckings (30) preferably have identical fittings (10) which are connected to decking profiles (32) of different heights, in particular in an identical manner. Particularly preferably, the scaffolding system has at least two scaffolding deckings (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the length (L.sub.32) of the decking profile (32) with lower maximum height (H.sub.32) is shorter than for the decking profile with higher maximum height (H.sub.32). In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffold decks (30), each having identical fittings (10) but decking profiles (32) with different maximum heights (H.sub.32), wherein further preferably the decking profiles (32) are of different lengths and have greater maximum heights (H.sub.32) with increasing length (L.sub.32).

[0034] FIG. 4 shows a side view of a third framework decking with a fitting according to FIGS. 1a and 1b and a third decking profile. There, a method of connection (three connection points arranged in an L-shape for bolting, riveting, toxing or welding) between the third fitting and the third decking profile is shown, preferably being the same as that shown in FIGS. 2 and 4.

[0035] FIG. 5a shows a side view of a scaffold decking according to FIG. 2, but with a different connection of the first decking profile to the fitting. A second type of connection by welding is shown here.

[0036] FIG. 5b shows a side view of the scaffold covering according to FIG. 5a without hidden edges.

[0037] FIG. 6a shows a side view of a scaffold decking according to FIG. 3, but with a different connection of the second decking profile to the fitting, whereby this connection is in particular identical to the connection shown in FIG. 5a.

[0038] FIG. 6b shows a side view of the scaffold covering according to FIG. 6a without hidden edges.

[0039] FIG. 7a shows a side view of a scaffold decking according to FIG. 4, but with a different connection of the third decking profile to the fitting, whereby this is in particular identical to the connection shown in FIGS. 5a and 6a.

[0040] FIG. 7b shows a side view of the scaffold covering according to FIG. 7a without hidden edges.

[0041] FIG. 1a shows a first fitting 10 for connection to a first horizontal ledger of a scaffold. The first fitting 10 has a fitting body 12. The fitting body 12 can be made of metal, in particular sheet metal. Support hooks 14a, 14b are provided for supporting the first fitting 10 on the first horizontal ledger. In the assembled state of the fitting 10, the first horizontal bar is overlapped by at least one gripping hook 16a, 16b, in particular by two gripping hooks 16a, 16b. A bracket 18 arranged movably relative to the fitting body 12 secures the first fitting 10 against lifting off, for example in the event of a gust of wind.

[0042] The first fitting 10 has two corner regions 20a, 20b into which a decking profile can be received. The corner regions 20a, 20b each have surfaces 22a, 22b, 22c, 22d formed at right angles to one another that both facilitate receiving the decking profile and allow effective load transfer from the decking profile into the first fitting 10. The corner portions 20a, 20b may be connected to a front face 24, the front face 24 preferably being connected to the face 22b and/or 22d at right angles.

[0043] FIG. 1b shows a front view of the first fitting 10 according to FIG. 1a. It can be seen from FIG. 1b that the front panel 24 has downwardly tapered side panels 26a, 26b to save weight. The gripping hooks 16a, 16b are formed offset from the horizontal center of the first fitting 10 so that another identical fitting can be arranged on the same first horizontal bar. The load capacity of the gripping hooks 16a, 16b is increased by at least one stiffening web 28a, 28b, 28c, 28d, preferably several stiffening webs 28a-28d.

[0044] FIG. 2 shows a first framework decking 30 with a first fitting 10 according to the first fitting 10 shown in FIGS. 1a and 1b, which is fixedly connected to a first decking profile 32, i.e., not detachable without tools. The vertical maximum height H32 of the first decking profile 32 exceeds the vertical maximum height H12 of the first fitting body 12, in particular by a factor max Kh=1.5 to 2.5.

[0045] FIG. 3 shows a second framework decking 34 with a second fitting 10′ according to the first fitting 10 shown in FIGS. 1a and 1b, which is fixedly connected to a second decking profile 36. The vertical maximum height H36 of the second decking profile 36 exceeds the vertical maximum height H12 of the second fitting body 12′, in particular by the factor mid Kh=1.1 to 1.5.

[0046] FIG. 4 shows a third framework decking 38 with a third fitting 10″ according to the first fitting 10 shown in FIGS. 1a and 1b, which is fixedly connected to a third decking profile 40. The vertical maximum height 1140 of the third decking profile 40 exceeds the vertical maximum height H12 of the third fitting body 12″, the latter preferably being coordinated with the maximum height H40 of the third decking profile 40.

[0047] As exemplarily shown in FIGS. 2 and 3, the decking profile 32, 36 can be rounded or have a rounding R on its underside towards the fitting 10, 10′ in order to avoid a notch effect when the framework decking 30, 34 is loaded.

[0048] The scaffold decks shown in FIGS. 2 to 4 each form, individually or together, a scaffolding system. The same fittings 10, 10′, 10″ are used within this scaffolding system, so that the scaffolding system can be completed in a particularly cost-effective manner. The scaffold decks 30, 34, 38 are preferably connected to the fittings 10, 10′, 10″—as shown in FIG. 4 with reference signs—by means of connections of identical type and manner (e.g. three connection points arranged in an L-shape for bolting, riveting, toxing or welding on side surfaces of the fittings 22a and 22c), in particular by means of welded connections 42a, 42b, 42c. The lower the maximum height H.sub.32, H.sub.36, H.sub.40 of the framework planks 30, 34, 38, the shorter they are preferably formed (see indicated lengths L.sub.32, L.sub.36 and L.sub.40). Since scaffold decks 30, 34, 38 of different lengths L.sub.32, L.sub.36, H.sub.40 preferably do not all have the same large maximum height H.sub.32, H.sub.36, H.sub.40, significant weight, energy used and costs are saved during transport and assembly of the scaffolding system.

[0049] FIGS. 5a and 5b show a first framework covering 30′ which corresponds to the first framework covering 30 according to FIG. 2 except for the differently formed welded joints 42d, 42e (in particular second type of welding).

[0050] FIGS. 6a and 6b show a second framework covering 34′ which corresponds to the second framework covering 34 according to FIG. 3 except for the differently formed welded joints 42d, 42e (in particular second method of welding according to FIGS. 5a and 5b).

[0051] FIGS. 7a and 7b show a third framework facing 38′ which is similar to the third framework facing 38 according to FIG. 4 except for the differently formed welded joints 42d, 42e (in particular second way of welding according to FIGS. 5a and 5b or FIGS. 6a and 6b).

[0052] Taking a synopsis of all figures of the drawing, the invention relates in summary to a scaffolding system with at least one scaffolding decking 30, 30′, 34, 34′, 38, 38′. The scaffolding decks 30, 30′, 34, 34′, 38, 38′ preferably have identical fittings 10, 10′, 10″ which are connected to decking profiles 32, 36, 40 of different heights, in particular in an identical manner. Particularly preferably, the scaffolding system has at least two scaffold deckings 30, 30′, 34, 34′, 38, 38′, each having identical fittings 10, 10′, 10″, but decking profiles 32, 36, 40 with different maximum height H.sub.32, H.sub.36, H.sub.38, wherein further preferably the length L.sub.32, L.sub.36, L.sub.40 of the decking pro-file 32, 36, 40 with lower maximum height H.sub.32, H.sub.36, H.sub.38 is shorter than in the case of the decking profile with greater maximum height H.sub.32, H.sub.36, H.sub.38. In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffold decks 30, 30′, 34, 34′, 38, 38′, each having identical fittings 10, 10′, 10″, but decking profiles 32, 36, 40 with different maximum heights H.sub.32, H.sub.36, H.sub.38, wherein further preferably the decking profiles 32, 36, 40 are of different lengths and have greater maximum heights H.sub.32, H.sub.36, H.sub.38 with increasing length L.sub.32, L.sub.36, H.sub.40.
