Description

Scaffolding system and method for manufacturing the scaffolding system

Background of the Invention

The invention relates to a scaffolding system according to the preamble of patent claim 1. The invention further relates to a method for producing such a scaffolding system. It is known to provide scaffolding systems, especially work and facade scaffolding systems, with a certain load class. Such scaffolding systems in particular comprise several scaffolding coverings. The known scaffolding coverings of a load class have covering profiles of the same height. The height of the covering profiles corresponds to the height of the fittings of the scaffold coverings that are connected to the covering profiles. The height of the decking profiles is generally independent of the length of the scaffolding decking. However, since the load capacity of the scaffolding decking depends on the length of the respective scaffolding decking, short scaffolding decking is oversized compared to long scaffolding decking with the same height of the decking profile. Object of the invention

It is therefore an object of the invention to provide a scaffolding system and a method for producing this scaffolding system, the scaffolding system being able to remove loads particularly effectively and at the same time being easier to manufacture.

Description of the invention

This object is achieved according to the invention by a scaffolding system according to patent claim 1 and a method for producing this scaffolding system according to patent claim 14. The subclaims represent preferred embodiments.

The designations "height", "length", "width", "top", "bottom" etc. refer to the assembled state of the scaffolding system. The scaffolding system can only include the first scaffolding covering or also other scaffolding covering.

The object according to the invention is thus achieved by a scaffolding system with a first scaffolding covering, the first scaffolding covering having a first covering profile for supporting an accessible first covering plate and a first fitting for connecting the first scaffolding covering to a first horizontal bar. The first fitting has a one-piece first fitting body which is fixedly connected to the first covering profile. The maximum height of the first covering profile exceeds the maximum height of the first fitting body, in particular by the factor max Kh = 1.5 to 2.5.

According to the invention, it is therefore provided that the first scaffolding covering has a fitting for reversibly releasably connecting the first scaffolding covering to a first horizontal bar. The height of this fitting (in the vertical direction) falls below the height of the first covering profile, which is preferably permanently connected to the first fitting. In this way, the first scaffolding covering is suitable for removing large loads and can nevertheless have a standardized first fitting. The first fitting body is preferably formed from sheet metal. This enables particularly simple and inexpensive production. The first fitting body can have two corner regions, each with surfaces bent at the right angle, on which the first covering profile rests in sections. As a result, the load transfer from the covering profile to the fitting is particularly reliable. The first scaffold covering can have an anti-lift device. The anti-lift device preferably has a bracket that can be moved relative to the fitting body for reaching under the first horizontal bar.

In a preferred embodiment of the first scaffold covering, the first covering profile is fastened 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 manufacture of the first scaffold covering.

The first covering profile is particularly preferably rounded on its underside toward the first fitting. In this way, notch stresses in the area of the underside of the first scaffold covering can be avoided.

The advantages according to the invention can be seen particularly clearly in a previously described scaffolding system with a second scaffolding covering, the second scaffolding covering having a second covering profile for supporting an accessible second covering plate and a second fitting for connecting the second scaffolding covering to a second horizontal bar, the second Fitting has a one-piece, ie one-piece, second fitting body which is fixedly connected to the second covering profile, the second fitting having the same design as the first fitting and the maximum height of the second covering profile being lower than the maximum height of the first covering profile. The factor mid Kh is preferably 1.1 to 1.5. As a result, covering profiles of different heights with the same, in particular identically designed, fittings can be used and preferably connected in an identical manner (screws, rivets, toxins and / or welding).

The second covering profile is particularly preferably shorter than the first covering profile. The second, shorter covering profile then has a lower covering profile height than the first covering profile. In other words, the second, shorter, covering profile is not oversized as a result and can be formed more easily.

The scaffolding system further preferably has a third scaffolding covering, the third scaffolding covering having a third covering profile for supporting an accessible third covering plate and a third fitting for connecting the third scaffolding covering to a third horizontal bar, the third fitting having a fixed connection with the third covering profile connected one-piece third fitting body; wherein the third fitting is of the same design as the second fitting and the maximum height of the third covering profile is lower than the maximum height of the second covering profile.

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

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

The object of the invention is further achieved by a method for producing a previously described scaffolding system, with the method step:

A) Fastening, in particular in the same manner, preferably by welding, the first covering profile to the first fitting body.

The method preferably has the following additional method step: B) fastening, in particular in the same way, preferably welding, the second covering profile to the second fitting body.

The method further preferably has the following additional method step:

C) Fastening, in particular in the same manner, preferably welding, the third covering profile to the third fitting body.

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

The method further preferably comprises the following method step:

D) Reversibly releasable arrangement of the first fitting on the first horizontal bar.

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

Further advantages of the invention result from the description and the drawing. Likewise, according to the invention, the features mentioned above and those which have been elaborated further can be used individually or in combination in any combination. The embodiments shown and described are not to be understood as an exhaustive list, but rather have an exemplary character for the description of the invention.

1 a shows a first fitting 10 for connection to a first horizontal bar of a scaffold. The first fitting 10 has a fitting body 12. The fitting body 12 can be formed from metal, in particular from sheet metal. Support hooks 14a, 14b are provided for supporting the first fitting 10 on the first horizontal bar. In the assembled state of the fitting 10, the first horizontal bolt is overlapped by at least one gripping hook 16a, 16b, in particular by two gripping hooks 16a, 16b. A bracket 18, which is movable 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 covering profile can be received. The corner regions 20a, 20b each have surfaces 22a, 22b, 22c, 22d formed at right angles to one another, which both facilitate the inclusion of the covering profile and also enable effective load transfer from the covering profile into the first fitting 10. The corner regions 20a, 20b can be connected to a front side 24, the front side 24 preferably being connected at right angles to the surface 22b and / or 22d.

FIG. 1b shows a front view of the first fitting 10 according to FIG. La. It can be seen from FIG. 1b that the front side 24 has side walls 26a, 26b tapering downwards in order to save weight. The gripping hooks 16a, 16b are offset from the horizontal center of the first fitting 10, so that a further 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 a plurality of stiffening webs 28a-28d.

FIG. 2 shows a first scaffold covering 30 with a first fitting 10 according to the one shown in FIGS. La and lb shown first fitting 10, which is fixed with a first covering profile 32, i.e. not detachable without tools, is connected. The vertical maximum height H32 of the first covering profile 32 exceeds the vertical maximum height H 12 of the first fitting body 12, in particular by the factor max Kh = 1.5 to 2.5. FIG. 3 shows a second scaffold covering 34 with a second fitting 10 'according to the one shown in FIGS. La and lb shown first fitting 10 which is fixedly connected to a second covering profile 36. The vertical maximum height H36 of the second covering profile 36 exceeds the vertical maximum height H 12 of the second fitting body 12 ', in particular by the factor mid Kh = 1.1 to 1.5.

FIG. 4 shows a third scaffold covering 38 with a third fitting 10 ″ in accordance with the first fitting 10 shown in FIGS. 1 a and 1 b, which has a third fitting Cover profile 40 is firmly connected. The vertical maximum height H40 of the third covering profile 40 exceeds the vertical maximum height H12 of the third fitting body 12 ″, which is preferably coordinated with the maximum height FUo of the third covering profile 40.

As exemplified in FIGS. 2 and 3, the covering profile 32, 36 can be rounded on its underside towards the fitting 10, 10 'or have a rounding R in order to avoid a notch effect when the scaffolding covering 30, 34 is loaded.

The in Figs. 2 to 4 scaffold coverings 30, 34, 38 each individually or together form a scaffolding system. The same fittings 10, 10 ', 10 "are used within this scaffolding system, so that the scaffolding system can be manufactured particularly cost-effectively. The connection of the scaffolding coverings 30, 34, 38 to the fittings 10, 10', 10" is preferably carried out - as in FIG 4 shown with reference numerals - by means of connections of an identical manner (for example three L-shaped connection points for screwing, riveting, toxing or welding on side surfaces of the fitting 22a and 22c), in particular by means of welded connections 42a, 42b, 42c . The lower the maximum height H 32, H 36, FUo of the scaffolding coverings 30, 34, 38, the shorter they are preferably designed (see indicated lengths L32, L36 and L40). Since scaffold coverings 30, 34, 38 of different lengths L32, L36, L40 preferably do not all have the same large maximum height H 32, H 36, H ₄ O, significant weight, energy and costs are saved when transporting and assembling the scaffolding system.

The figures 5a and 5b show a first scaffold covering 30 'which corresponds to the first scaffolding covering 30 according to FIG. 2 except for the differently designed welded connections 42d, 42e (in particular the second type of welding). The figures 6a and 6b show a second scaffold covering 34 ', which corresponds to the second scaffolding covering 34 according to FIG. 3 except for the differently designed welded connections 42d, 42e (in particular the second type of welding according to FIGS. 5a and 5b). The figures 7a and 7b show a third scaffold covering 38 'which, apart from the differently designed welded connections 42d, 42e (in particular the second type of welding according to FIGS. 5a and 5b or FIGS 6a and 6b).

Taking all the figures of the drawing together, the invention relates in summary to a scaffolding system with at least one scaffold covering 30, 30 ', 34, 34', 38, 38 '. The scaffold coverings 30, 30 ', 34, 34', 38, 38 'preferably have the same fittings 10, 10', 10 ", which are connected to cover profiles 32, 36, 40 of different heights, in particular in an identical manner. The scaffolding system particularly preferably has at least two scaffolding coverings 30, 30 ', 34, 34', 38, 38 ', each with identical fittings 10, 10', 10 ", but covering profiles 32, 36, 40 with different maximum heights H32, H36, H38, the length L32, L36, L40 of the covering profile 32, 36, 40 with a lower maximum height H32, H36, H 38 being more preferably shorter than in the covering profile with a larger maximum height H32, H36, H38. In a further preferred embodiment of the invention, the scaffolding system comprises at least three scaffolding coverings 30, 30 ', 34, 34', 38, 38 ', the identical fittings 10, 10', 10 ", but covering profiles 32, 36, 40 with lower have different maximum heights H32, H36, H38, further preferably the covering profiles 32, 36, 40 are of different lengths and, with increasing length L32, L36, L ₄ o, have greater maximum heights H32, H36, H38.
