Description

The invention relates to an arrangement of scaffolding components for a facade scaffolding or a facade scaffolding with the features of the preamble of claim 1.

Today, such facade scaffolding is often constructed in such a way that the railings are installed in advance. In this context one speaks of leading railings. For this purpose, a fitter who is standing on the ground or on a lower floor designed with at least one scaffolding floor can, from there, first install a first railing and, if necessary, on a first scaffolding post that has already been set up or mounted to build a next higher floor Releasably attach a second railing with one or a first railing end. The fitter can then releasably attach the second railing end or the respective second railing end of the respective railing to a second scaffolding pole, which he holds with one hand, preferably while supporting the second scaffolding pole with its lower pole end on the ground or on the scaffolding floor the lower floor. In the case of two railings, these are each detachably attached to the respective scaffolding post at a longitudinal distance from one another. The fitter, still standing on the floor or on the scaffolding floor of the lower floor, can then install the first railing, or simultaneously the first and second railings, starting from an assembly position in which the respective railing is at an angle to the first scaffolding post this extends downwards, with the help of the second scaffolding handle by manually grasping the second scaffolding handle Hand and by manually placing it upwards, pivot the railing(s) upwards and attach the second scaffolding pole, with the railing(s) releasably attached to it, onto a third scaffolding pole. In this or a similar way, the railing or railings on the next higher floor are transferred to a horizontal installation position and form a pre-installed railing there. The fitter, still standing on the ground or on the scaffolding floor of the lower floor, can then attach another scaffolding floor at a desired height to complete the next higher floor, which is then already counteracted by the railings installed in advance or by the railings installed in advance prevent people from falling. If only a first railing is mounted in advance, this is preferably mounted at a first height at which it forms a hip or back railing with respect to the further scaffolding floor arranged immediately below. If a second railing is also mounted in advance at the same time, this is preferably mounted at a second height below the first height, which is selected so that the second railing forms a knee railing with respect to the further scaffolding floor.

From the EP 1 983 129 A2 and the WO 2008/128500 A2 The applicant has become aware of a rigid U-shaped scaffolding frame for a facade scaffolding or a facade scaffolding. In this scaffolding frame, two parallel vertical supports are rigidly connected to one another in the area of their upper support ends at fastening positions provided at the same height via a single cross arm extending perpendicular to the vertical supports. A single perforated disk, which is provided with through openings, is attached to each support by welding at the respective fastening position. The through openings are used to wedge rod elements provided with so-called connection heads onto the vertical supports. Longitudinal beams and cross beams are usually used as bar elements. The cross arm has a connection head with an insertion slot at its fastening ends that extend away from each other, via which the respective connection head is plugged onto the respective perforated disk and there and on the respective one Vertical support is welded in place. On one of the two vertical supports, two railing fastening devices are attached below the perforated disk at a longitudinal distance from one another, with a first railing fastening device of the railing fastening devices being attached just below the longitudinal center of the associated vertical support, and a second railing fastening device the railing fastening devices are attached approximately in the middle between the first railing fastening device and the lower support end of this vertical support. Each railing fastening device comprises a holder and a locking lever which can be pivoted about a pivot axis relative to the holder. The bracket is attached to the associated vertical support by welding. The holder is a U-shaped bracket. A through opening in the form of a vertical receiving slot is formed between the bracket wall parts of the bracket and the outer wall of the support, which extends parallel to the longitudinal axis of the support. The locking lever can be pivoted from an open position into a locking position. The railing devices in the form of balusters can be installed both from the same scaffold layer or, if necessary, from a scaffold layer or floor below to create a leading railing. For this purpose, the respective railing bar can be hooked or threaded into the bracket designed as a bracket from below, in particular diagonally from below, preferably with the locking lever in its locking position, i.e. closed. For this purpose, the railing bar is inserted with part of a railing bar end of its railing bar ends into the vertical receiving slot placed or suspended on a horizontal support surface of a support element of the holder and then pivoted upwards into a horizontal installation position. The railing bars used there each have a hanging hook on their respective two railing bar ends, by means of which these railings can be releasably hung or fastened to the U-bolts. These railing bars cannot be hung with their hanging hooks in the through openings of the respective perforated disk. The lifting of these railings from the U-bolts can only be prevented if when the assigned locking levers are pivoted into their locking position.

In the parallel US 2010/0089697 A1 The applicant is illustrated using additional figures and describes how a leading railing can be constructed. As part of this, an alternative embodiment of a scaffolding frame is also shown and described, which is a rigid H-shaped scaffolding frame. There, the two parallel vertical supports are rigidly connected to one another in the area of their longitudinal center at fastening positions provided at the same height via a single cross arm extending perpendicular to the vertical supports. Here, too, a single perforated disc, which is provided with through openings, is attached to each support by welding at the respective fastening position. On each of the two vertical supports, two railing fastening devices are attached above the perforated disk at a longitudinal distance from one another, with a first railing fastening device of the railing fastening devices being attached approximately in the longitudinal center between the perforated disk and the upper support end of the associated vertical support, and wherein the second railing fastening device of the railing fastening devices is fastened in the area of the upper support end of this vertical support. The brackets and locking levers are designed in the same way as already described and shown in the parallel intellectual property rights. However, it is also possible for other H-shaped scaffolding frames to be used instead of these H-shaped scaffolding frames, in which only one vertical support of the two vertical supports, which are rigidly connected to one another by means of a corresponding cross arm, can be provided with at least one of the same railing fastening device, but can preferably also be provided with two identical railing fastening devices. To set up a leading railing, the scaffolder must manually raise the H-shaped scaffolding frame together with a railing device that is releasably attached to it. The railing bars disclosed there cannot be hooked into the through openings of the respective perforated disc with their hanging hooks become. Even with these designs, the railings can only be prevented from being lifted out of the U-brackets if the associated locking levers are pivoted into their locking position.

In the WO 02/057569 A1 The installation of leading railings is also covered. Scaffolding posts are disclosed there, to which one or more rosettes are permanently attached. These rosettes can each be a perforated disk with several through openings. The balusters disclosed there have hooks on each baluster end of their two baluster ends. These hanging hooks are designed in such a way that they can each be releasably attached to the rosette or a rosette of the rosettes by inserting the free hook part of the respective hanging hook through a through opening of the through openings of the associated rosette. When a railing of these railings is pivoted upwards with the help of a scaffolding pole of these scaffolding poles, this railing can be lifted vertically out of the rosette of the associated other, already erected or assembled scaffolding pole. This

Document discloses the features of the preamble of claim 1. Also WO02072977 discloses the features of the preamble of claim 1.

It is an object of the invention to provide an arrangement of scaffolding components of the type mentioned at the outset, in which the risk of the railing being lifted out of the associated rosette during the early assembly of the railing and the resulting risk of injury, in particular to people, is reduced or is eliminated.

several assembly phases that occur during an advanced assembly of the in the Figures 4.1 and 4.2 shown railing device can occur one after the other.

The Figure 1 shows a partially constructed facade scaffolding 20, to illustrate a starting position before an advance assembly of the two railing bars 22.1.1, 22.1.2 shown on the left of the associated two identical railing devices 21.1.1, 21.1.2. These railing devices 21.1.1, 21.1.2 are each equipped with a long scaffolding pole 23 that has already been set up vertically; 23.1 detachably connected and pivotable relative to it. The two railing devices 21.1.1, 21.1.2 extend parallel to each other and each obliquely to the horizontal and also obliquely to the scaffolding pole longitudinal axes 24, 24.1, 24.2.

The Figure 1 shows the partially constructed facade scaffolding 20 in an intermediate assembly phase before the two railing devices 21.1.1, 21.1.2 are pivoted upwards and placed on the short scaffolding stem 23.3 shown on the left, using the long, second scaffolding post 23.2 shown on the left.

This in Figure 1 The partially constructed facade scaffolding 20 shown is shown in a very simplified manner. It is known to those skilled in the art with the help of which additional scaffolding components, such as base spindles, horizontal longitudinal beams, horizontal cross beams and diagonals, such facade scaffolding in the form of so-called modular scaffolding can be erected safely and stably.

The facade framework 20 includes several individual vertical posts 23; 23.1, 23.2, 23.3, which are each modular scaffolding posts. The facade scaffolding 20 is or is constructed from individual, short modular scaffolding posts 21.3. These each have a pipe connector 25. The short modular scaffolding poles 21.3 are or will be set up in such a way that their pipe connector 25 projects vertically upwards. The short scaffolding poles 21.3 each have an effective scaffolding pole length 26.3, which is approximately 1 m. There are two perforated disks 30 on each of the short modular scaffolding posts 21.3; 30.1, 30.2 permanently attached. The two perforated disks 30; 30.1, 30.2 are, viewed in the direction of the respective scaffolding post longitudinal axis 24.3 of the respective short scaffolding post 21.3, fastened to one another at a longitudinal distance 27 of approximately 50 cm corresponding to a grid dimension.

On the in the Figure 1 shown, front, first long side 28.1 of the facade scaffolding 20 are or are plugged onto the pipe connectors 25 of the vertical, individual, short modular scaffolding stems 23.3 vertical, individual, long modular scaffolding stems 23, 23.1, 23.2. These long modular scaffolding stems 23; 23.1, 23.2 extend in the direction of their scaffolding handle longitudinal axes 24, 24.1, 24.2 in a straight line from their lower handle end to their upper handle end over an effective handle length 26, 26.1, 26.2. The effective still length 26, 26.1, 26.2 is approximately 2 m. At their upper ends, these individual scaffolding posts 23; 23.1, 23.2 each have a pipe connector 25 for attaching another vertical post, in particular a scaffolding post or modular scaffolding post.

At the upper end of each scaffolding stem 23; 23.1, 23.2, 23.3 a contact area is designed for setting up the next highest scaffolding pole. The respective contact area forms the respective upper end of the handle and limits the effective handle length upwards. The respective pipe connector 25 extends upwards over the respective contact area. Each individual scaffolding post 23; 23.1, 23.2, 23.3 consists of a round tube made of galvanized steel with an outer circumference and an outer diameter. The scaffolding pole longitudinal axes 24; 24.1, 24.2, 24.3 of the individual scaffolding posts 23; 23.1, 23.2, 23.3 are arranged or set up parallel to one another. Adjacent individual scaffolding posts 23; 23.1, 23.2, 23.3 of these individual scaffolding posts 23; 23.1, 23.2, 23.3 are arranged at a longitudinal distance from one another. On each of these individual scaffolding posts 23; 23.1, 23.2, 23.3 are several rosettes 30 in one grid dimension corresponding longitudinal distance 27 to one another permanently attached by welding. The uppermost perforated disc or rosette 30 is attached at a rosette distance from the respective upper end of the handle. The lowest rosette 30 in each case has a second rosette distance from the respective lower stem end of these scaffolding stems 21.1, 21.2. The second rosette spacing is larger than the first rosette spacing.

Each rosette is designed as a perforated disk 30. Like in particular Figure 3 illustrated, each perforated disk 30 has eight through openings 31.1, 31.2. These are designed as through holes. Each perforated disk 30 has four, oval-shaped, small through-openings 31.1 and four, trapezoidal, large through-openings 31.2. The small and large through-openings 31.1 and 31.2 are each arranged offset from one another in the circumferential direction, so that each small through-opening 31.1 is followed in the circumferential direction by a large through-opening 31.2, and vice versa. Immediately adjacent through openings 31.1, 31.2 are each arranged offset from one another in the circumferential direction at an equally large circumferential angle 32. The circumferential angle 32 is 45 degrees.

The through openings 31.1, 31.2 of each perforated disk 30; 30.1, 30.2, 30.3, 30.4 are outward, i.e. in a radial, first direction perpendicular to the respective scaffolding pole longitudinal axis 24; 24.1, 24.2, 24.3, 24.4 away from this, limited by outer rosette wall parts 33.1. These outer wall parts are each a rosette web. The no through openings 31.1 of the through openings 31.1, 31.2 of each perforated disk 30; 30.1, 30.2, 30.3, 30.4 are delimited inwards, i.e. in a second direction opposite to the first direction, by inner rosette wall parts 33.2. These form inner webs. Immediately adjacent through openings 31.1, 31.2 are delimited by radially extending separating webs 34.

Each perforated disk 30 completely surrounds the scaffolding tube of the associated scaffolding post 23, which is designed as a round tube. Each perforated disc is 30 designed as a circular disk. The inner diameter of each perforated disk 30 is slightly larger than the respective outer diameter of the respective scaffolding tube of the respective scaffolding post 23 onto which they are attached. Each perforated disk 30 is welded to the associated scaffolding tube of the respective scaffolding post 23. Each perforated disk 30 has a substantially constant disk thickness 35, for example 9 mm or 10 mm. Each perforated disk 30 has a first side surface 36.1 and a second side surface 36.2 pointing in an opposite direction and extending parallel to the first side surface 36.1. In the erected state of each scaffolding post 23, the first side surface 36.1 of each perforated disk 30 forms the top side and the second side surface 36.2 forms the underside of the perforated disk 30. Each perforated disk 30 is delimited radially inwards by an inner end face which has an inner diameter. Each perforated disk 30 is limited radially outwardly by an outer front edge 37 with an outer front surface 38 which has an outer diameter. The inner end face and the outer end face 38 are arranged concentrically to one another. The circumferential outer end face 38 extends perpendicular to the first side surface 36.1 and perpendicular to the second side surface 36.2. The first side surface 36.1 of each perforated disk 30, which is upper in the erected state, goes over a circular first perforated disk edge 39.1, which is an upper edge of the perforated disk 30 in the erected state of the scaffolding pole in question, into the circumferential outer end face 38 of the circumferential outer Front edge 37 across. The second, lower side surface 36.2 of each perforated disk 30 when erected goes over a circular second perforated disk edge 39.2, which is a lower edge of the perforated disk 30 in the erected state of the affected scaffolding post 23, into the circumferential outer end face 38 of the circumferential outer -Front edge 37 across.

In the Figures 4.1 and 4.2 a first exemplary embodiment of a first railing device is shown. This railing device is referred to as the first railing device 21.1.

The connection head 52 forms the second railing end 40.2 of the first railing device 21.2. The connection head 52 is captively connected to a fastening wedge 53, which can be pushed through a through opening 31.1, 31.2 of the through openings 31.1, 31.2 of a perforated disk 30 and by means of which the connection head 52 can be releasably attached to a perforated disk 30 of another or second scaffolding post 23.2. The connection head 52 has an upper head part 54.1 and a lower head part 54.2, which are connected to one another in one piece via a connecting part 55. The upper head part 54.1 and the lower head part 54.2 are separated from one another by a slip-on slot 56 which is horizontal in the installed position. The connection head 52 can be plugged onto a perforated disk 30 of the perforated disks 30 via its attachment slot 56. Such connection heads, for example those of the applicant, have been known for many years and are also referred to as wedge heads due to their wedge-shaped outer contour. Each connection head 52 is permanently connected via its respective connection part 55 by welding to a U-bracket 57, which is open in the direction away from the connection head 52. The U-bracket 57 is secured to the second railing bar end 41.2 of the first railing bar 22.1 of the first railing device 21.1 by means of a joint 58, for example a cylinder screw 59, preferably with a hexagon head, which is secured with a nut 60, preferably a hexagon nut, screwed onto its thread. preferably releasable, attached. The connection head 52 provided with the U-bracket 57 can be pivoted relative to the first railing bar 22.1 about a pivot axis or joint axis 61 of the joint 58 relative to the first tube 44.1 or to the first railing bar 22.1. The pivot axis 61 extends perpendicular to the first baluster longitudinal axis of the first baluster and extends parallel to a slot center plane 62 of the slip-on slot 56 of the connection head 52. In addition, the pivot axis 61 extends perpendicular to a slot center plane 63 of the first receiving slot 46.1.1 of the first tube 44.1 or extends perpendicular to a longitudinal center plane 64 of the suspension hook 50 formed from a flat material, which forms the other, first railing bar end 41.1 of the first railing bar 22.1 of the first railing device 21.1.

The hook 50 is manufactured in the form of a separate component which is Figures 6 and 7 is shown. The suspension hook 50 is designed as a plug-in component which is intended to be inserted into the first tube end 45.1.1 of the first tube 44.1 of the first railing rod 22.1. The suspension hook 50 is a hook plate 51. The suspension hook 50 consists of a flat material, preferably flat steel. The suspension hook 50 or the hook plate 51 has a flat first side surface 65.1 and a flat second side surface 65.2, which is formed parallel to the first side surface 65.1. The two side surfaces 65.1, 65.2 extend away from each other in opposite directions. The suspension hook 50 or the hook plate 51 is delimited around its circumference by an end surface 66, which is formed perpendicular to the side surfaces 65.1, 65.2.

The hanging hook 50 has a hook nose 67 at its front end facing away from the first 44.1 tube. The hook nose 67 extends away from a hook wall part 68 which is upper in the installed position and downwards in the installed position. The hook nose 67 has a front outer contour 69 in the form of a front edge. The front edge 69 has a cross-section that is rounded towards the front in a cutting plane parallel to the parallel side surfaces 65.1, 65.2. The hook nose 67 has a free gripping hook end 70. The rear-grip hook end 70 extends in the direction of the second railing bar end 41.2 to the rear 77, parallel to the first first railing bar longitudinal axis 42.1.

The first railing bar end 41.1 has a first recess 73 on the underside 72 in the horizontal installation position 71.1 of the first railing bar 22.1. The recess 73 is open to the side surfaces 65.1, 65.2 and downwards 74 which extend away from one another. The first recess 73 of the hanging hook 50 is delimited by contact support surfaces 78.1 to 78.7 of a railing bar end support part 79. The recess 73 comprises a rosette wall part receiving space 80, which is suitable and intended for at least partially accommodating a rosette wall part 33.1 of the rosettes 30, which has a through opening 30.1 of the through openings 30; 30.1, 30.2 of the respective perforated disk 30 limited radially outwards.

The hook nose 67 of the hanging hook 50 goes in one piece into the upper hook wall part at its end facing away from the free hook end 70 68 over. The upper hook wall part 68 is limited by an upper contact support surface 78.1 of the contact support surfaces 78.1 to 78.7, which limits or delimits the rosette wall part receiving space 80 of the recess 73.

The upper hook wall part 68 merges in one piece towards the rear 77 and downwards 74 into a recess-limiting wall part 81 of the hanging hook 50. This has a contact support surface 78.2 of the contact support surfaces 78.1 to 78.7, which limits the rosette wall part receiving space 80 of the recess 73 to the rear 77. This contact support surface 78.2 is referred to as the upper contact support surface. This contact support surface 78.2 of the recess-limiting wall part 81 encloses a first angle 82 with the first railing bar longitudinal axis 42.1 of the first railing bar 22.1, which is preferably 90 degrees.

The rear-grip wall part 83 has a free rear-grip element end 84, which extends forward 76 in the direction of the free rear-grip hook end 70 of the hook nose 67 of the hanging hook 50. The rear gripping element 83 encompasses the rosette wall part receiving space 80 of the recess 73 with its rear gripping element end 84. The hook nose 67 also engages with its rear gripping hook end 70 over the rosette wall part receiving space 80 of the recess 73. The free rear gripping element end 84 of the rear-grip element 83, viewed in the direction of the railing bar longitudinal axis 42.1, 42.2, has a distance 99 corresponding to the smallest recess width of the recess 73 from the free rear-grip hook end 70 of the hook nose 67 of the hanging hook 50.

The rear gripping element 83 is limited at the top 75 by an upper contact support surface 78.3 of the contact support surfaces 78.1 to 78.7. This extends from the free rear-grip element end 84, which is a Edge, which extends perpendicular to the two side surfaces 65.1, 65.2, diagonally upwards 75.

The upper contact support surface 78.3 of the rear gripping element 83 merges over a very small radius into the contact support surface of the recess boundary wall part 81, forming a bend 85 in the form of a transverse edge. The upper contact support surface 78.3 of the rear gripping element 83 encloses a second angle 86 with the first railing bar longitudinal axis, which is preferably approximately 66 degrees.

The upper contact support surface 78.3 of the rear gripping element 83 encloses a third angle 87 with the upper contact support surface 78.2 of the recess boundary wall part 81, which is preferably approximately 156 degrees.

The rear gripping element 83 is limited at the bottom 74 by a lower contact support surface 78.4 of the contact support surfaces 78.1 to 78.7. Starting from the free rear-grip element end 84, this extends obliquely downwards 74 and rearwards 77. This lower contact support surface 78.4 extends obliquely to the first railing rod longitudinal axis 41.1 at a fourth angle 88, which here is approximately 45 degrees.

The rear gripping element 83 merges obliquely downwards 74 and rear 77 in one piece into a lower support wall part 89, which is delimited by an inclined contact support surface 78.5 of the contact support surfaces 78.1 to 78.8. The lower contact support surface 78.4 of the rear gripping element 83 merges downwards 74 and behind 77 without kinks into the contact support surface 78.5 of the support wall part 89, so that these two contact support surfaces 78.4, 78.5 have a common, preferably flat, contact surface. Form support surface 78.6.

The second railing bar 22.2 extends in a straight line in the direction of its second railing bar longitudinal axis 42.2. The second railing bar 22.2 has the first railing bar end 90.1 and a second railing bar end 90.2 pointing in an opposite direction. The first railing bar end 90.1 is designed with a first hanging hook 50 and the second railing bar end 90.2 is designed with a second hanging hook 50. The second baluster end 90.2 is designed in the same way as the first baluster end 90.1.

The second railing bar 22.2 comprises an elongated, straight second tube 44.2, preferably a round tube. The tube 44.2 has a first tube end 45.2.1 and its second tube end 45.2.2 extending therefrom in an opposite direction. The tube 44.2 extends in the direction of its longitudinal axis 91.2. In each pipe end 45.2.1, 45.2.2 of the pipe 44.2, a hook plate 51 of the two identical hook plates 51, 51 is inserted into a receiving slot 46.1.1, 46.1.2 and is permanently connected to the pipe 44.2 by welding. The two suspension hooks 50, 50 or the two hook plates 51, 51 extend parallel to the pipe's longitudinal axis and contain the pipe's longitudinal axis 91.2. The two hanging hooks 50, 50 or hook plates 51, 51 extend with their parallel side surfaces along a longitudinal central plane 92.1, 92.2, which contains the pipe longitudinal axis 91.2 or the baluster longitudinal axis 42.2.

The second railing bar 22.2 is designed symmetrically to a bar center plane 93 containing the two longitudinal center planes 92.1, 92.2 of the two suspension hooks 50, 50. This can also be referred to as the longitudinal center symmetry plane. In addition, the second baluster 22.2 is designed symmetrically to a transverse center plane 94, which is perpendicular to the pipe longitudinal axis 91.2 or perpendicular to the second baluster longitudinal axis 42.2. The transverse center plane 94 can also be marked with .

The second railing device 21.2 is a second railing bar 22.2. The second railing device 21.2 has a first railing end 43.1 and a second railing end 43.2, which extends away from the first railing end 43.1 in an opposite direction. The second baluster 22.2 has a first baluster end 90.1 and a second baluster end 90.2, which extends away from the first baluster end 90.1 in an opposite direction. The first railing end 43.1 or the first railing bar end 90.1 of the second railing device 21.2 and the second railing end 43.2 or the second railing bar end 90.2 of the second railing device 21.2 are designed the same. In this second exemplary embodiment, the first railing end 43.1 and the second railing end 43.2 are designed the same. In addition, in this second exemplary embodiment, the first baluster end 90.1 of the second baluster 22.2 and the second baluster end 90.2 of the second baluster 22.2 are designed the same.

The following describes the assembly of a leading railing using two identical first railing devices 21.1.1, 21.1.2, which are shown in the Figures 4.1 and 4.2 are shown and each of which is a railing device 21.1, which is shown in the Figures 4.1 and 4.2 are shown.

The procedure is based on a first erected scaffolding field 95.1, which is in Figure 1 , greatly simplified, is illustrated by the scaffolding posts 23, 24, 23.1, 24.1 shown in the middle of the sheet and on the right edge of the sheet and by the two upper, identical railing devices 21.1, which have their respective railing ends on the upper, long one shown in the middle of the picture Scaffolding handle 23.1 as well as on the upper, long scaffolding handle 23 shown on the right edge of the sheet are releasably attached. The upper railing device 21.1 is fastened to the top, fourth perforated disk 30.4 of the four perforated disks 30 of the two long scaffolding poles 23.1, 23 in a horizontal installation position 71.1, while the lower railing device 21.1 is attached to the third perforated disk 30.3 immediately below the fourth perforated disk of the respective scaffolding post 23.1, 23 is fastened in a horizontal installation position 71.2.

For the purpose of early assembly of the railing devices 21.1.1, 21.1.2 for the in Figure 1 left, greatly simplified, second scaffolding field 95.2 shown on the left can be proceeded as follows:
First, a fitter, not shown in the figures, hangs a first railing device 21.1.1 with its hanging hook 50 on its first railing end 40.1, i.e. on its first railing bar end 41.1, in a first through opening 31.1 of the third perforated disk 30.3 of the already erected, long, first scaffolding post 23.1 a. The fitter can then let this first railing device 21.1.1 hang down due to gravity. The fitter then hangs a second, identical railing device 21.1.2 with its hanging hook 50 at its first end of the railing, i.e. at its first end of the railing bar, into a first through opening 31.1 of the fourth perforated disk 30.4 of the long, first scaffolding post 23.1 that has already been erected. The fitter can then also let this second railing device 21.1.2 hang down due to gravity. It goes without saying that the reverse procedure can also be carried out, i.e. the second railing device 21.1.2 can be hung first and then the first railing device 21.1.1.

The fitter then takes another, second, long scaffolding pole 23.2, which is designed in the same way as the first scaffolding pole 23.1, which also carries four of the perforated disks 30, and transports it manually into an area in which he can use the second one formed with the connection head 52 Railing end of the second railing device 21.1.2 can be reached with one hand. There the fitter then manually brings together the connection head 52 of the second railing device 21.1.2, which is already suspended on the fourth perforated disk 30.4 of the first scaffolding post 23.1, with the fourth perforated disk 30.4 of the second scaffolding post 23.2, onto which he then attaches this second connection head 52 with its slot 56 . The fitter then aligns this second connection head 52 relative to the fourth perforated disc 30.4 of the second scaffolding post 23.2 in such a way that its fastening wedge 53 can be pushed through a small, first through-opening of the through-openings 31.1, 31.2 of the fourth perforated disc 30.4 of the second scaffolding post 23.2. The fitter then inserts this fastening wedge 53 through this small, first through opening of the fourth perforated disk 30.4 without wedged it there.

The fitter then manually brings together the first connection head 52 of the first railing device 21.1.1, which is already suspended on the third perforated disk 30.3 of the first scaffolding post 23.1, with the third perforated disk 30.3 of the second scaffolding post 23.2, onto which he then attaches this first connection head 52 with its slot 56 . The fitter then aligns this first connection head 52 relative to the third perforated disk 30.3 of the second scaffolding post 23.2 in such a way that its fastening wedge 53 can be pushed through a small, first through opening of the through openings 31.1, 31.2 of the third perforated disk 30.3 of the second scaffolding post 23.2. The fitter then inserts this fastening wedge 53 through this small, first through opening in the third perforated disk 30.3 without wedgeing it there.

The fitter can then attach the first connection head 52 and the second connection head 52 to the by means of their respective fastening wedge 53, 53 Wedge the second scaffolding post 23.2, for example by hitting each with a hammer. Now an assembly phase has been reached in which the second scaffolding post 23.2 is aligned vertically and the in Figure 1 is illustrated on the left.

Now the fitter can manually guide the second scaffolding post 23.2 upwards together with the two railing devices 21.1.1, 21.1.2 which are releasably attached to it and can be pivoted relative to it, into an assembly position in which the fitter can place the second scaffolding post 23.2 on a lower, third scaffolding pole 23.3 can be attached. This is the case in Figure 1 The example shown is about the short scaffolding post 23.3 with two perforated disks 30 shown on the left. It goes without saying that in order to build the next higher floor, the next long scaffolding posts can be placed on the long scaffolding posts that have already been assembled.

After raising and placing the long, second scaffolding post 23.2 on the short, third scaffolding post 23.3, an assembly phase is reached, which is in Figure 2 is illustrated. In this assembly phase, the first railing device 23.1.1 is in a horizontal installation position 71.1 and the second railing device 21.1.2 is also in a horizontal installation position 71.2. If a scaffolding floor, which is not shown in the figures, is mounted at the level of the second perforated disk 30.2 of both the first scaffolding post 23.1 and the second scaffolding post 23.2, the first railing device 21.1.1 can function as a knee railing or as a knee bar and the second railing device 21.1.2 can function as a handrail or as a hip or back railing. In the exemplary embodiment according to Figure 2 Both the first railing device 21.1.1 and the second railing device 21.2.2 are mounted in advance.

Below, using the example in the Figures 4.1 and 4.2 shown first railing device 21.1, based on Figures 8.1 to 8.8 several assembly phases are described that can occur during an early assembly of this first railing device 21.1.

In the Figure 8.1 a first assembly phase is illustrated, in which the first railing bar 22.1, which has the first railing bar end 41.1, is fed to the first railing device 21.1 for the purpose of its advance assembly of a first perforated disk 30 of a first scaffolding post 23.

In the Figure 8.2 a subsequent, second assembly phase is illustrated, in which the first railing bar 22.1 of the first railing device 21.1 is guided with its first railing bar end 41.1 up to just in front of the first perforated disk 30 of the first scaffolding post 23 in the area of a first through opening 31.1 whose through openings 31.1, 31.2.

In the Figure 8.3 a subsequent, third assembly phase is illustrated, in which the first railing bar 22.1 of the first railing device 21.1 is brought further up to the first perforated disk 30 in such a way that it is connected to an oblique stop surface 78.6, which is also referred to as a common contact support surface The outer end face 38 of a first rosette wall part 33.1 of the rosette 30, designated with the outer boundary surface, bears against a first through opening 31.1 of the through openings of the rosette 30 in a direction perpendicular to the first scaffolding post longitudinal axis 24.1 of the first scaffolding post 24.1 away from this to the outside limited. This oblique stop surface 78.6 is the contact support surface 78.6 which is formed from the lower contact support surface 78.4 of the rear gripping element 83 and from the contact support surface 78.5 of the lower support wall part 89 of the hanging hook 50.

In the Figure 8.4 a subsequent, fifth assembly phase is illustrated, in which the first railing bar 22.1 of the first railing device 21.1 starting from the assembly position according to Figure 8.3 with an inclination that remains the same or with an inclination angle 98.1 of the first railing bar 22.1 that remains the same of approximately 45 degrees, with the hook nose 67 of its hanging hook 50 downwards due to gravity was dropped, so that its hook nose 50 extends through the first through opening 31.1 of the perforated disk 30 and the hanging hook 50 is supported on the first rosette wall part 33.1. The hanging hook 50 is supported with the upper contact support surface 78.1 of the upper hook wall part 68, which delimits the rosette wall part receiving space 80 of the recess 73, on the front outer edge 39.1 of the first rosette wall part 33.1 of the rosette 30 and is supported the rear contact support surface 78.7 of the hook nose 67 delimiting the rosette wall part receiving space 80 of the recess 73 on the inner edge 39.3 of the first rosette wall part 33.1 of the first rosette 30. From this assembly phase onwards, the first railing bar 22.1 is in a first railing bar assembly intermediate position, from which the first railing bar 22.1 can be pivoted upwards relative to the first scaffolding post 23.1 to build a leading railing with the aid of the second scaffolding post 23.2, not shown here . is pivoted upwards.

In the Figure 8.5 a subsequent, sixth assembly phase is illustrated, which is achieved when the first railing bar 22.1 of the first railing device 21.1, for example in the direction of the in Fig. 8.4 arrow 96 shown at the bottom left, i.e. in the direction of the railing bar longitudinal axis 42.1 of the first railing bar 22.1 of the first railing device 21.1 is moved forward 76, in particular in the course of a simultaneous upward pivoting of the first railing bar 22.1 relative to the first scaffolding post 23.1. This can result in the formation of compressive forces that are so great that the first railing bar end 41.1 of the first railing bar 22.1 moves in the direction of the Figure 8.4 shown arrow 96 can come. The first railing bar 22.1 can be moved with its first railing bar end 41.1 until the hook nose 67 with its rounded front outer contour 69 rests on an inner contour 29 of the first through opening 31.1 of the first perforated disk 30 of the first scaffolding post, viewed in the direction forward 76 23.1 is present. As can be seen, the free hook end is 70 the hook nose 67 of the hanging hook 50 compared to the one in Figure 8.4 shown support position moved forward 76 and upwards 75. Even in this support position, the hanging hook 50 is still supported by the upper contact support surface 78.1 of the upper hook wall part 68, which delimits the rosette wall part receiving space 80 of the recess 73, on the front outer edge 39.1 of the first rosette wall part 33.1 of the rosette 30 away.

In the Figure 8.6 a subsequent, seventh assembly phase is illustrated, which is achieved when the first railing bar 22.1 of the first railing device 21.1, in particular with a simultaneous upward pivoting or by a simultaneous upward pivoting of the first railing bar 22.1 relative to the first scaffolding post 23.1, further in In the direction of the railing bar longitudinal axis 42.1 of the first railing bar 22.1, compressive forces are applied which are so large that the hook nose 67, due to its rounded front outer contour 69, moves in the direction of the in the Figure 8.5 arrow 97, further forward 76 and upwards 75 is moved. As can be seen, the free hook end 70 of the hook nose 67 of the hanging hook 50 is opposite that in Figure 8.5 Support position shown moved further upwards, with the free hook end 70 now located in the first through opening 31.1 of the first perforated disk 30. As can also be seen, in this position of the first railing bar 22.1 of the first railing device 21.1, the rear recess-limiting wall part 81 of the hanging hook 50, which delimits the rosette wall part receiving space 80, is supported with its contact support surface 78.2 on the lower edge or lower perforated disk edge 39.2 of the first rosette wall part 33.1 of the first rosette 30. In this assembly phase, a second intermediate railing rod assembly position 48 is reached.

In the Figure 8.7 A subsequent, eighth assembly phase is illustrated, which is achieved when the first railing device 21.1 with its second railing end 40.2 is pivoted further upwards relative to the first scaffolding post 23.1 by lifting the second scaffolding post 23.2 (not shown here), a larger one being used as an example Tilt angle 98.2 of approx. 55 degrees relative to the horizontal is reached. In complex tests it has been shown that the problem of the formation of compressive forces and that the resulting risk of the suspension hook 50 being lifted out with its lower, free hook end 70 can increase significantly at angles of inclination relative to the horizontal that are greater than 45 Degree. So if the second scaffolding post 23.2 is raised further, so that the first handrail 22.1 is pivoted upwards even more relative to the first scaffolding post 23.1, so that the angle of inclination of the first handrail longitudinal axis 42.1 relative to the horizontal is increased to more than 45 degrees, increases the risk of the formation of compressive forces through which the first railing bar 22.1 of the first railing device 21.1 is acted upon further in the direction of its railing bar longitudinal axis 42.1. These compressive forces can, as in the example according to Figure 8.6 shown, become so large that the hook nose 67 of the hanging hook 50, which is rounded at the front and continues to be supported on the inner contour 29 of the first through opening 31.1, is raised there further upwards 75 relative to the rosette 30. As a result, the free rear-grip hook end 70 of the hanging hook 50 of the first railing bar end 41.1 can be raised to such an extent that it is only just arranged in the first through opening 31.1 of the first perforated disk 30, i.e. it has not yet been lifted out.

According to the invention, the lifting of the free rear-grip hook end 70 and thus the suspension hook 50 of the first railing bar 22.1 and consequently the one-sided lifting of the first railing device 21.1 is prevented by the fact that the first railing bar end 41.1 of the first railing bar 22.1 is designed with the rear-grip element 83 the rosette wall part receiving space 80 of the recess 73 and partially overlaps it, and which lies opposite the first hook nose 67 of the first hanging hook 50, and that extends forward in the direction of the free rear-grip hook end 70 of the hook nose 67 of the hanging hook 50 extending, free rear-grip element end 84, which also delimits the rosette wall part receiving space 80 of the recess 73 and partially overlaps it.

Like in the Figure 8.7 shown, the rear gripping element 83 of the hooking hook 50 comes into contact with the lower outer edge 39.2 of the first rosette wall part 33.1 of the first rosette 30 due to the upward pivoting of the first railing bar 22.1 of the first railing device 22.1 by means of the second scaffolding post 23.2, not shown here Engages and engages behind the first rosette wall part 33.1, which is located to a large extent in the rosette wall part receiving space 80, on its underside with its free rear grip element end 84. This results in the free rear grip hook end 70 of the hanging hook 50 of the first railing bar end being lifted out 41.1 of the first railing bar 22.1 of the first railing device 21.1 and thus effectively prevents the railing device 21.1 from being lifted out on one side from the first through opening 31.1 of the first rosette 30.

In the Figure 8.8 a subsequent, ninth assembly phase is illustrated, in which the first railing bar 22.1 of the first railing device 21.1 was pivoted further upwards relative to the first scaffolding pole 23.1 with the aid of the second scaffolding post 23.2, not shown here, and in which the second scaffolding post 23.2 is pivoted onto one in this figure lower scaffolding post 23.3, also not shown, was placed (see Figures 1 and 2 each on the outside left), whereby the first railing device 21.1 with its first railing bar 22.1 has now been transferred to its horizontal installation position 71 as a leading or leading railing.
