Description

INVENTION BACKGROUND

The invention relates to a scaffolding system according to the generic term of claim 1. The invention further relates to a method for manufacturing such a scaffolding system.

It is known to provide scaffolding systems, especially working and facade scaffolding systems, with a certain load class. Such scaffolding systems comprise in particular several scaffold deckings. The known scaffold deckings of a load class have decking profiles of the same height. The height of the decking profiles corresponds to the height of the fittings of the scaffold deckings connected to the decking profiles in each case. The height of the decking profiles is generally independent of the length of the scaffold deckings. However, since the load capacity of the scaffold deckings depends on the length of the respective scaffold deckings, short scaffold deckings are oversized compared to long scaffold deckings with the same height of the decking profiles.

OBJECT OF THE INVENTION

It is therefore the object of the invention to provide a scaffolding system and a method for manufacturing this scaffolding system, whereby the scaffolding system can carry loads particularly effectively and at the same time can be finished in a simplified manner.

DESCRIPTION OF THE INVENTION

This object is solved according to the invention by a scaffolding system according to claim 1 and a method for manufacturing this scaffolding system according to claim 14. The subclaims give preferred embodiments.

The designations “height”, “length”, “width”, “top”, “bottom”, etc. refer to the assembled state of the scaffolding system.

The scaffolding system can include only the first scaffold decking or additional scaffold deckings.

The object according to the invention is thus solved by a scaffolding system with a first scaffolding decking, wherein the first scaffolding decking has a first decking profile for supporting a walkable first decking panel and a first fitting for connecting the first scaffolding decking to a first horizontal ledger. The first fitting comprises a one-piece first fitting body fixedly connected to the first decking profile. The maximum height of the first decking profile exceeds the maximum height of the first fitting body, in particular by a factor max Kh=1.5 to 2.5.

According to the invention, it is thus provided that the first scaffold decking has a fitting for reversibly releasably connecting the first scaffold decking to a first horizontal ledger. The height of this fitting (in the vertical direction) is less than the height of the first decking profile, which is preferably non-detachably connected to the first fitting. In this way, the first scaffold decking is suitable for carrying large loads and can still have a standardized first fitting.

Preferably, the first fitting body is made of sheet metal. This enables particularly simple and cost-effective production.

The first fitting body can have two corner areas, each with surfaces bent at right angles, on which the first decking or covering profile rests in sections. This ensures particularly reliable load transfer from the decking profile to the fitting.

The first scaffold decking can have an anti-lift device. The anti-lift device preferably has a bracket that can be moved relative to the fitting body to engage under the first horizontal ledger.

In a preferred embodiment of the first scaffold covering, the first decking profile is attached to the first fitting body with at least one L-shaped screw, rivet, tox and/or welded connection. Such a welded connection enables reliable and simple fabrication of the first scaffold decking.

Particularly preferably, the underside of the first decking profile is rounded towards the first fitting. Notch stresses in the area of the underside of the first framework covering can thus be avoided.

The advantages of the invention are particularly evident in a previously described scaffolding system with a second scaffold deck, the second scaffold decking having a second decking profile for supporting a walkable second decking and a second fitting for connecting the second scaffold decking to a second horizontal ledger, the second fitting having a one-piece, i.e. integral, second fitting body firmly connected to the second decking profile, the second fitting being of the same design as the first fitting and the maximum height of the second decking profile being lower than the maximum height of the first decking profile, the second fitting having a one-piece second fitting body fixedly connected to the second decking profile, the second fitting being of the same design as the first fitting and the maximum height of the second decking profile being lower than the maximum height of the first decking profile. Preferably, the factor mid Kh is equal to 1.1 to 1.5. In this way, decking profiles of different heights can be used with identical, in particular identically designed, fittings and can preferably be connected in an identical manner (bolting, riveting, toxing and/or welding).

Particularly preferably, the second lining profile is shorter than the first lining profile. The second, shorter lining profile then has a lower lining profile height than the first lining profile. In other words, the second, shorter, decking profile is thus not oversized and can be formed more easily.

Further preferably, the scaffolding system comprises a third scaffold deck, the third scaffold decking comprising a third decking profile for supporting a walkable third decking and a third fitting for connecting the third scaffold decking to a third horizontal ledger, the third fitting comprising a one-piece third fitting body fixedly connected to the third decking profile;

wherein the third fitting is formed the same as the second fitting and the maximum is height of the third decking profile is lower than the maximum height of the second decking profile.

The maximum height of the third decking profile can be matched to the maximum height of the third fitting body, in particular it can correspond to the maximum height of the third fitting body.

In a further preferred embodiment of the scaffolding system, the third decking profile is shorter than the second decking profile. The height of the decking profile is preferably lower the shorter the decking profile. In this way, the scaffolding system can be designed to be particularly weight- or load-effective.

The object according to the invention is further solved by a method for manufacturing a previously described scaffolding system, comprising the method step:

• A) Fastening, in particular in the same way, preferably welding, of the first decking profile to the first fitting body.

Preferably, the method comprises the following additional process step:

• B) Fastening, in particular in the same way, preferably welding, of the second decking profile to the second fitting body.

Further preferably, the method comprises the following additional process step:

• C) Fastening, in particular in the same way, preferably welding, of the third lining profile to the third fitting body.

Process steps A), B) and C) can be carried out in any order.

Further preferably, the method comprises the following process step:

• D) Reversibly detachably arranging of the first fitting on the first horizontal bar.

Previously, simultaneously or subsequently, the second fitting (and/or the third fitting) can be reversibly releasably arranged on the first horizontal latch.

Further advantages of the invention can be seen from the description and the drawing. Likewise, the above-mentioned and the still further elaborated features can be used according to the invention in each case individually or as a plurality in any desired combination. The embodiments shown and described are not to be understood as a conclusive list, but rather have an exemplary character for the description of the invention.

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

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.

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

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.

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.

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.

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.

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.

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.

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.

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 H₃₂, H₃₆, H₄₀ of the framework planks 30, 34, 38, the shorter they are preferably formed (see indicated lengths L₃₂, L₃₆ and L₄₀). Since scaffold decks 30, 34, 38 of different lengths L₃₂, L₃₆, H₄₀ preferably do not all have the same large maximum height H₃₂, H₃₆, H₄₀, significant weight, energy used and costs are saved during transport and assembly of the scaffolding system.

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).

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).

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).

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 H₃₂, H₃₆, H₃₈, wherein further preferably the length L₃₂, L₃₆, L₄₀ of the decking pro-file 32, 36, 40 with lower maximum height H₃₂, H₃₆, H₃₈ is shorter than in the case of the decking profile with greater maximum height H₃₂, H₃₆, H₃₈. 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 H₃₂, H₃₆, H₃₈, wherein further preferably the decking profiles 32, 36, 40 are of different lengths and have greater maximum heights H₃₂, H₃₆, H₃₈ with increasing length L₃₂, L₃₆, H₄₀.
