Such a framework and such a method is from EP 1 845 215 A1 and from the parallel EP 1 961 886 A2 known. There, a suspension hook of a scaffolding floor is secured against lifting out of a U-profile of a U-profile carrier formed with two parallel support legs by means of an anti-lift body in the form of a perforated disk that overlaps the suspension hook. On its side facing away from the U-profile, the U-profile support has a connecting part which is integrally connected to it. The connection part has two fastening legs, each extending laterally beyond the two support legs of the U-profile, via which the U-profile carrier is releasably fastened to an elongated scaffolding tube by means of a connection pipe coupling designed with a coupling half-shell. The perforated disk has a through hole through which a securing tab is inserted, which at its securing tab end facing the U-profile has a slot nut which is releasably fastened in a guide groove of the U-profile support. The perforated disk is clamped against the hook of the scaffold floor in the area of one end of the securing tab facing away from the U-profile by means of a securing wedge that extends over the perforated disk, which in turn is clamped to the corresponding support edge of the U-profile relative to the latter via the perforated disk. As a result, the suspension hook and consequently the scaffolding floor cannot be displaced relative to the longitudinal axis of the U-profile of the U-profile support. In order to make this possible, the securing wedge would first have to be released by means of a tool such as a hammer, removing the jamming. But then there would be the risk of the hook of the scaffolding floor being unintentionally lifted out of the U-profile and consequently the scaffolding floor falling down, which would pose a risk to life and limb. In addition, if the anti-lift device could only then be moved along the U-profile, the perforated disk would, due to gravity, tip over into a free space between adjacent hooks either on the scaffold floor or from adjacent scaffold floors or slide down completely into this free space between the two adjacent hooks, so that then another move the anti-lift device would not be possible without lifting the perforated disk back to at least its clamping height position.

From the CH 439 679 PS scaffolding has become known in which the catwalks, which are formed from catwalk frames and in these wooden shutters, and in which the catwalk frames are provided with transverse parts made from downwardly open hook-on U-profiles. The suspension U-profiles each extend along a cross-connecting web of a vertical support frame of the scaffolding. The cross-connecting web is a U-shaped web that is open at the top. To secure the suspension of the suspension U-profiles of the scaffolding floors, a cylindrical screw penetrates the cross-connecting web in a through-hole and is rigidly connected at the top to a stop plate. A spacer made of an upwardly open U-profile piece, which has a through hole through which the screw extends, is arranged under the stop plate between this and a base of the upwardly open U-profile cross-connecting web. The stop plate of the screw, also referred to as a pressure plate, is designed as a rectangular plate, its stop plate longitudinal axis extending transversely, ie perpendicular to the longitudinal axis of the cross-connecting web. The screw is provided with a nut on its screw end protruding from the underside of the cross-connecting web. By tightening the nut, the stop plate of the screw is pressed onto the suspended U-profiles and the latter is secured against unhooking. The spacer avoids unnecessary cross play between the hanging U-profiles of the scaffolding decks in the U-profile cross-connecting web, which is open at the top. As a result, this safety device has the same disadvantages as the above-mentioned construction.

As a result, accessories, such as one or more suspension shoes for carrying or hanging up the U-profile carrier and / or one or more post adapters for connecting one or more scaffolding posts to the U-profile carrier despite the anti-lift device installed in Longitudinal areas where no hooks are arranged can be easily attached to the U-profile support.

According to a further development, it can be provided that the anti-lift-out and support body is designed as an elongated rail extending in the direction of the longitudinal axis of the anti-lift-off body. As a result, several scaffolding floors lying next to one another, viewed in the direction of the U-profile beam longitudinal axis, can be secured particularly easily and safely by means of one and the same anti-lift and support body against their hooks being lifted out of the U-profile.

According to a particularly preferred development it can be provided that the anti-lift and support body by means of a first fastening device and by means of a second fastening device with the U-profile carrier against lifting of the hook or the hook of the at least one scaffold floor from the U-profile of the U-profile support is secured, the first fastening device and the second fastening device, viewed in the direction of the U-profile support longitudinal axis of the U-profile support, are arranged at a distance from one another, and that the first fastening device the clamping device and the second fastening device is the quick-locking device or that it is the first fastening device the clamping device and the second fastening device is a corresponding or the same clamping device or that the first fastening device is the quick-locking device and the second fastening device is a corresponding or the same quick-locking device , and that the anti-lift body has a number of through openings corresponding to the number of fastening devices, each of which is designed such that the respective locking body together with a fastening body part of the respective fastening body in the direction of its fastening body longitudinal axis and perpendicular to the longitudinal axis of the fastening groove can be plugged through the respective through opening. By means of these measures, particularly flexible options for securing the anti-lift device on the U-profile carrier can be achieved, as a result of which the assembly flexibility can be improved even further.

It goes without saying that the aforementioned measures can be combined with one another in any way within the scope of the attached claims within the scope of the feasibility.

The Figure 1 shows a scaffold 20, which can be suspended as a hanging scaffold on structures not shown, for example on a bridge not shown. For this purpose, at least two suspension devices 21.1, 21.2 are provided. Each suspension device 21.1, 21.2 comprises a support device 22, which is preferably to be arranged vertically, and a fastening device 23 detachably fastened to it for the detachable fastening of a respective U-profile support 24.1, 24.2. In the embodiment shown, both U-profile supports 24.1, 24.2 are designed the same. For this reason, the reference symbol 24 is used uniformly below for U-profile girders. The fastening device 23 is a suspension shoe (see also Figure 3 ). Each support device 22 comprises a threaded rod 25 which is to be releasably fastened to the structure (not shown) with its upper threaded rod end 26 pointing away from the suspension shoe 23. A similar support device is from DE 10 2016 103 224 A1 became known to the applicant. Each suspension shoe 23 comprises several, preferably welded together, metal plates, namely a support plate 27 for placing the associated U-profile support 24.1, 24.2, a first trapezoidal side plate 28.1 for laterally supporting the associated U-profile support 24 and a second trapezoidal side plate 28.2 for the lateral support of the associated U-profile beam 24, which are each fastened in the region of their wider trapezoidal side to the support plate 27 and which extend perpendicularly and parallel to each other, as well as a support plate 29, which is attached to the two trapezoidal side plates 28.1, 28.2 are each attached in the region of their narrow trapezoidal side. The support plate 27, the two side plates 28.1, 28.2 and the support plate 29 enclose a receiving space 30, which is rectangular in cross section, for detachably receiving the associated U-profile support 24. Each U-profile support 24 is supported on the support plate 27 of the associated receiving shoe 23. Each U-profile support 24 can be moved relative to the associated suspension shoe 23 for positioning, as long as the latter is not yet attached to the associated U-profile support 24 by means of fastening means.

In Figure 1 two U-profile girders 24 are shown, which extend parallel and at a transverse distance from one another. Each U-profile support 24 is a support made of aluminum using an extrusion process.

This can also be referred to as an extruded aluminum U-profile beam. Each U-profile support 24 extends as an elongated profile in a straight line in a direction parallel to its U-profile support longitudinal axis 34. In the embodiment shown, the two U-profile supports 24 have the same U-profile support. Length of, for example, about 4 m or about 5 m or about 6 m or about 7 m. It goes without saying, however, that the U-profile girders can also have different U-profile girder lengths. In particular, each U-profile support 24 has the same cross-section in an imaginary sectional plane perpendicular to its U-profile support longitudinal axis 34 (see FIG Figure 3 ). The U-profile girders 24 can be connected by means of longitudinal connectors (not shown) to one or more other corresponding U-profile girders, also not shown, in order to achieve a desired or required span.

Each U-profile support 24 comprises a plate-shaped lower wall 35 and two plate-shaped side walls 36.1, 36.2 extending perpendicularly away from it in the same direction, which extend parallel to one another at a transverse distance 37 corresponding to the width of the lower wall 35. The transverse distance corresponds to the width of the U-profile beam 24, for example 52 mm. The lower wall 35 and the two side walls 36.1, 36.2 are outer walls of the U-profile beam 24. The outer surfaces of the side walls 36.1, 36.2 and the lower wall 35 are designed essentially flat. At a distance from the lower wall 35, which is much greater than the width of the lower wall, a transverse wall 38 is formed, which extends transversely to the two side walls 36.1, 36.2 between them. Each side wall 36.1, 36.2 is provided with a plurality of, preferably circular, fastening holes 39 for fastening the suspension shoe 23 and other accessories, in particular those in FIG Figure 1 Connection adapters 40 shown are provided for the detachable connection of further scaffolding components such as scaffolding handles and / or scaffolding bars. The fastening holes 39 are arranged in two parallel longitudinal rows 41.1, 41.2 which are arranged at a height distance 42 from one another. The mounting holes 39 point in the direction of respective longitudinal row 41.1, 41.2 viewed, each have an identical hole spacing 43 to one another. An equal number of fastening holes 39 is provided in each longitudinal row 41.1, 41.2. All fastening holes 39 are preferably designed in the same way.

Each U-profile support 24 comprises a box-shaped, in cross-section essentially rectangular, cross-sectionally closed, elongated hollow profile 45, the cavity 69 of which with the lower wall 35 delimiting a bottom of the hollow profile 45, with the two side walls 36.1, 36.2 and with the transverse wall 38 is limited. The hollow profile 45 of each U-profile support 24 has, viewed in a direction perpendicular to its longitudinal center plane 46, a hollow profile width 47 and, viewed perpendicular to this direction in an imaginary sectional plane formed perpendicular to the longitudinal center plane 46, a hollow profile height 48 which is much larger than the hollow profile width 47.

Each U-profile support 24 has a U-profile 31 on its side opposite the lower wall 35. Each U-profile 31 is formed with the respective transverse wall 38 and with two support legs 33.1, 33.2, which are arranged parallel to one another and parallel to the longitudinal center plane 49 of the U-profile 31. Each side wall 36.1, 36.2 merges on the outside in an aligned manner into the associated support leg 33.1, 33.2, which extends the respective side wall 36.1, 36.2. Each support leg 33.1, 33.2 has an outer surface which is designed essentially flat and which is flush with the outer surface of the associated side wall 36.1, 36.2. Each U-profile support 24 is designed symmetrically to its longitudinal center plane 46, which contains the longitudinal center plane 49 of the respective U-profile 31. Each U-profile support has a U-profile support height 112 of, for example, 280 mm.

Each U-profile support 24 has a guide and fastening groove 51 which is delimited by the respective transverse wall 38 and which is open in the direction of the support edges 50.1, 50.2 of the support legs 33.1, 33.2 and on the inside thereof and which opens transversely in a transverse direction the support legs 33.1, 33.2 and in one The longitudinal direction perpendicular to the transverse direction in the direction of its longitudinal axis 52 extends parallel to the U-profile support longitudinal axis 34 of the U-profile support 24. The guide and fastening groove 51 is delimited by groove-behind gripping webs 53.1, 53.2 which are arranged at the same height along the inner sides of the two support legs 33.1, 33.2 and which, starting from the support legs 33.1, 33.2, extend inwardly towards one another to extend. A longitudinal slot 55, for example 16 mm wide, is formed between the opposite ends 54.1, 54.2 of the groove-behind-engagement webs 53.1, 53.2. The groove behind engagement webs 53.1, 53.2 delimit a locking space 56 of the guide and fastening groove 51, in which a locking body 74.1, 74.2 can be releasably arranged at several positions along the guide and fastening groove 51. The guide and fastening groove 51 and the longitudinal slot 55 extend in the longitudinal direction of the U-profile support 24 parallel to its U-profile support longitudinal axis 34 continuously over the entire U-profile support length. The U-profile 31 of each U-profile support 24 is symmetrical to its longitudinal center plane 46 containing the U-profile support longitudinal axis 34.

The transverse wall 38 of the respective U-profile support 24 has a guide groove 58, which is open towards the locking space 56 of the guide and fastening groove 51, for at least one support body 59.1, 59.2, 59.3 of an anti-lift and support body 60 according to the invention. The guide groove 58 extends in a longitudinal direction of the guide groove parallel to the longitudinal axis 52 of the guide and fastening groove 51 continuously over the entire U-profile support length of the U-profile support 24. The guide groove 58 is at the same distance from the guide groove to the outer surfaces of the U-profile support 24. The longitudinal center plane 61 of the guide groove 58 coincides with the longitudinal center plane 49 of the U-profile 31. The groove base 62 of the guide groove 58 is delimited by a transverse wall part 63 of the transverse wall 38 that extends into the interior of the hollow profile 45 of the U-profile support 24.

On each U-profile carrier 24 there are optional additional components such as the connection adapter 40 for connecting and supporting scaffolding posts and scaffolding bars, such as cross bars, longitudinal bars and diagonals, on the respective U-profile carrier 24 by means of fastening means such as bolts 64 releasably set. These bolts 64 are inserted through two aligned fastening holes 39 of the fastening holes 39 provided in the side walls 36.1, 36.2 of the U-profile support 24 concerned. At the connection adapters 40, as in Figure 1 shown, scaffolding posts, in particular of a modular scaffolding, can be releasably attached to which further scaffolding components, in particular longitudinal bars, cross bars and diagonals can be attached directly or indirectly.

With the aim of being flexible for the respective local conditions, in particular with regard to height ratios and inclinations, at least one carrier connection device 65 can optionally be detachably attached to one or to each U-profile carrier 24. The at least carrier connection device 65 can optionally according to a first alternative, which is shown in FIG Figure 1 is shown, using a scaffolding tube to be connected to a scaffolding post which is releasably attached to the U-profile support 24 by means of at least one connection adapter 40. According to a second alternative, not shown, the carrier connection device can optionally be detachably fastened directly to the U-profile carrier. By selecting the fastening holes 39 for the bolting, the storage condition of the U-profile support 24 can be realized in an articulated or rigid manner and the height of the U-profile support 24 can be varied, albeit to a lesser extent than in the said first alternative. On the U-profile girders 24, girder connection devices 65 for flexible direct or indirect support and / or fastening of the respective U-profile girder 24 to the structure, not shown, can therefore optionally be attached, preferably releasably.

In the U-profiles 31, which are open to the outside and at the top, the U-profile supports 24, which extend parallel to one another at a transverse distance, are alongside one another horizontal scaffolding floors 44 extending perpendicular to the U-profile girders 24 are suspended with their suspension hooks 32. The suspension hooks 32, which are each designed as so-called U-claws in the exemplary embodiment, are fastened to the narrow end faces 66 of the scaffolding floors 44, preferably by welding. In contrast to so-called O-claws, which are designed and intended for hanging in O-profiles like scaffolding tubes having a round cross-section, U-claws 32 are designed and intended for hanging in U-profiles, in particular in U-profiles 31. In the exemplary embodiment shown, two suspension hooks 32 are arranged at a transverse distance from one another on each narrow end face 66 of each scaffold floor 44. When viewed in one direction away from the respective running and working surface of the associated scaffolding floor 44, each suspension hook 32 is open, that is to say in the installed position downwards, and on both sides.

It goes without saying that three or more parallel U-profile supports 24 can also be provided, which can each be arranged at a transverse distance from one another. Then in the U-profile 31 at least one U-profile support 24, which is arranged in the transverse direction, between two other parallel U-profile supports, i.e. viewed in the transverse direction, on the inside, further scaffolding floors 44 with their hooks 32 can be hung in this way be that the suspension hooks 32 rest on both support legs 33.1, 33.2 of the U-profile 31 of this inner U-profile carrier 24 from transversely or perpendicularly from the inner U-profile beam 24 extending away from each other scaffolding floors 44, as for example in the Figures 5 , 7th , 8th and 10 shown.

At least one suspension hook 32 of the suspension hook 32 or several or all of the suspension hook 32 of the suspension hook 32 are secured against being lifted out of the respective U-profile 31 of the respective U-profile support 24 by means of several anti-lift devices 70.1, 70.2 according to the invention . The anti-lift devices 70.1, 70.2 are releasably attached to the U-profile support 24.

Each anti-lift device 70.1, 70.2 preferably contains at least two fastening devices 71.1, 71.2 and one anti-lift and support body 60. Each fastening device 71.1, 71.2 comprises a fastening body 73.1, 73.2, a locking body 74.1, 74.2 and a securing body 75.1, 75.2. The respective rod-shaped fastening body 73.1, 73.2 extends in the direction of its fastening body longitudinal axis 76.1, 76.2. Each locking body 74.1, 74.2 extends in the direction of its locking body longitudinal axis 77.1, 77.2 perpendicular to the fastening body longitudinal axis 76.1, 76.2 of the respective fastening body 73.1, 73.2. Each locking body 74.1, 74.2 is rigidly connected to the associated fastening body 73.1, 73.2. The respective securing body 75.1, 75.2 is arranged on the respective fastening body 73.1, 73.2 at a distance 78.1, 78.2 from the respective locking body 74.1, 74.2. The securing body 75.2 extends transversely or perpendicularly to the fastening body longitudinal axis 76.2 of the fastening body 73.2.

According to the invention, the anti-lift body 67 extending in the direction of its anti-lift body longitudinal axis 68 is part of a anti-lift and support body 60. The latter is in particular in the Figures 11 , 12.1, 12.2 and 12.3 shown. The anti-lift and support body 60 extends in a straight line in a direction parallel to the longitudinal axis 68 of its anti-lift body 67.

Based on the in Figure 8 Locking position 97.2 shown, the locking body 74.2 can be rotated about the fastening body longitudinal axis 76.2 into an unlocking position 98.2 by means of the fastening body 73.2 of the quick-locking device 96.2 designed with the flat web 121, which is shown in FIG Figure 10 is shown. In this unlocked position 98.2, the locking body 74.2 can by means of or by means of the fastening body 73.2 designed with the flat web 121 in a direction perpendicular to the longitudinal axis 52 of the guide and fastening groove 51 away from the transverse wall 38 of the U-profile support 24 away from the guide and Fastening groove 51 can be moved through the longitudinal slot 55.

The following is based on the Figures 17 to 19 and with reference to the Figures 7 to 9 a method for securing a plurality of scaffolding floors 44 of a scaffold 20, which can preferably be suspended or suspended as a hanging scaffold, against lifting of the hanging hooks 32 arranged on its narrow end faces 66 from the U-profile 31 of the U-profile support 24 is described, one being a quick-lock -Vorrichtung 96.2 designed fastening device 71.2 is used. The quick locking device 96.2 has already been described above and is in the Figures 15 , 16.1, 16.2 and 16.3 shown.

If not already done, the scaffolding floors 44 are first hung with their hooks 32 in the U-profile 31 of the U-profile support 24 in such a way that their hooks 32 on the support edges 50.1, 50.2 of the two support legs 33.1, 33.2 of the U-profile 31 of the U-profile support 24 rest. In the in the Figures 17 to 19 Shown embodiment are on each side of the U-profile 31 of the U-profile support 24 several scaffolding floors 44 with their opposite longitudinal end faces, viewed in the transverse direction, arranged side by side. The suspension hooks 32 of a first number of scaffolding floors 44 rest on the support edge 50.1 of a first support leg 33.1 of the two support legs 33.1, 33.2 of the U-profile 31 of the U-profile support 24 and the suspension hooks 32 of a second number of additional scaffolding floors 44 rest the support edge 50.2 of the second support leg 33.2 of the support legs 33.1, 33.2 of the U-profile 31 of the U-profile support 24. These scaffolding floors 44 are arranged in such a way that two of the scaffolding floors 44 lying on both sides of the U-profile 31 of the U-profile support 24 lie approximately in a straight line.

After hooking the hooks 32 of the scaffolding floors 44 into the U-profile 31 of the U-profile support 24, an anti-lift and support body 60 according to the invention is mounted on the U-profile support 24 in such a way that it is connected to support body ends 79.1, 79.2.1, 79.2.2, 79.2.3, 79.3 of its support bodies 59.1, 59.2, 59.3 is supported on the groove base 62 of the guide groove 58 of the transverse wall 38 of the U-profile beam 24 and, with its anti-lift body 67, the associated hooks 32 of the scaffolding floors 44 overlaps. For this purpose, the anti-lift and support body 60 with its support bodies 59.1, 59.2, 59.3 is inserted vertically downwards from above between the opposing hooks 32 of the scaffolding floors 44.

Subsequently, in the exemplary embodiment shown, one of the fastening devices 71.2 designed as a quick-locking device 96.2 is mounted. For this purpose, a fitter, not shown, grips the safety flap 111 with one of his hands, preferably by reaching through the reach-through opening 131 of the safety flap 111 with one or two of his fingers. Because of the articulated connection of the fastening body 73.2 to the securing flap 111, the fastening body 73.2 then hangs vertically or perpendicularly downward together with the locking body 74.2 due to the force of gravity. If not already done, the fitter then rotates the safety flap 111, still holding the safety flap 111 freely in his hand so that the locking body 74.2 reaches an inserted position 99.2 in which it can be inserted from above through one of the through openings 81.1 of the anti-lift body 67 of the anti-lift and support body 60 (see FIG Figure 17 ). Subsequently, the fitter, still holding the safety flap 111 freely in his hand, leads or sticks the locking body 74.2 vertically downwards through the said through opening 81.1 of the anti-lift body 67 of the anti-lift and support body 60 and continues this insertion or insertion movement vertically at the bottom until the securing body 75.2 of the securing flap 111 rests on the outer surface 88 of the anti-lift body 67 of the anti-lift and support body 60 (see FIG Figures 18 and 10 ).

The fitter then, still holding the safety flap 111 in his hand, rotates the safety flap 111 through an angle of approximately 90 degrees around the fastening body longitudinal axis 76.2 of the fastening body 73.2, whereby, due to the design, the locking body 74.2 also rotates this angle around the fastening body. Longitudinal axis 76.2 is also rotated (see Figure 18 ). The locking body 74.2 is then in a locking position 97.2 (see FIG Figure 18 ), in which it engages behind the groove-behind-engagement webs 53.1, 53.2 of the guide and fastening groove 51 of the U-profile support 24 (see Figure 8 ).

Meanwhile, or at the same time or afterwards, the fitter, still holding the safety flap 111 in his hand, rotates the safety flap 111 about the transverse axis 114 in the direction of the outer surface 88 of the anti-lift body 67 of the anti-lift and support body 60 until the plate-shaped safety flap 111 Section 129 rests on said outer surface 88 of anti-lift-out body 67, so that a locking position 116 of safety flap 111 is reached in which its anti-rotation body 134 engages in an associated safety opening 135 of anti-lift body 67 (see FIG Figures 19 and 9 ). In this locking position 116 of the locking flap 111 is a Securing against unintentional turning of the safety flap 111 about the fastening body longitudinal axis 76.2 and consequently against unintentional turning of the locking body 74.2 from its locking position 97.2 into its unlocking position 98.2 achieved.

The anti-lift and support body 60 is even when the locking body 74.2 of the quick-locking device 96.2 is in its locking position 97.2, in a displacement direction parallel to the U-profile beam longitudinal axis 34 relative to the U-profile beam 24 or along the U-profile support 24, regardless of the pivoted position in which the securing flap 111 is located relative to the fastening body or to the anti-lift-out body 67, i.e. in particular also in the securing position 116 of the securing flap 111 .
