Description

The invention relates to a connection arrangement having the features of the preamble of claim 1.

From the EP 1 911 907 A1 the applicant shows a vertical frame element with a first post, to which a single perforated disc is fastened by welding in the region of its upper post end. A first connection head, provided with a slip-on slot, of a transverse arm designed with a round tube, which extends perpendicularly away from the first post, is plugged onto the perforated disk. The first connection head formed on the round tube of the transverse arm is welded to the perforated disk of the first post and its outer circumference. At its end pointing away from the first post, the transverse arm has a separate, second connection head which is welded to the round tube. The second connection head also has a plug-on slot with which it is plugged onto a perforated disk of a second stem and wedged again releasably there by means of a wedge. The perforated disk of the second post is attached to the second scaffold post below the longitudinal center of the latter. Accordingly, the second connection head is connected via a separate, second stem of the same length, but with a perforated disk attached at different heights, to form a bending and torsion-resistant lateral frame. Two railing fastening devices in the form of bolts are attached to the second post above its perforated disk, which are identical in design and which extend away from the scaffolding post perpendicular to the longitudinal axis thereof. The second stem is on a short stem with the formation of a lateral vertical frame installed to connect a leading railing. A scaffold can be built from this vertical frame element, which is created with the formation of a facade frame with a leading railing. With the railing fastening devices of said second post, railing devices, in particular those which are designed with at least one handrail or as a handrail, the handrail ends of which have a fastening or suspension recess that is open to side surfaces extending away from one another and at the bottom, cannot be hooked in and secured against falling without additional components. Said separate, second handle has the features a) to g) of claim 1.

A similar scaffolding frame with two scaffolding standards is from the EP 1 672 140 A2 known. This scaffolding frame also contains a single, second scaffolding post. A single perforated disk is also attached to this second scaffolding post below its longitudinal center. This second scaffolding post is provided with vertical sockets and with horizontal sockets, on each of which a hook-shaped end, not described in detail, of a diagonal or lateral scaffolding element can be suspended. A first horizontal bushing is fastened close below the perforated disk and a second horizontal bushing appears to be fastened above the perforated disk at a distance from the lower end of the handle which, measured from the figures, corresponds to about 80% of the handle length. A first vertical socket appears to be attached in the area of the upper end of the stem. A second vertical bushing appears to be attached at a level just below the longitudinal center between the upper end of the stem and the perforated disc. A scaffold element, which is not described in detail, can be attached to the said sockets, but it is unclear how. This second scaffolding post has the features a) to d) and h) to m) of claim 1.

Another similar, single scaffolding standard is from the EP 2 083 132 A2 become known in the form of a scaffolding stand for system scaffolding for scaffolding structures. This in turn carries a near below its longitudinal center Perforated disc and has two fastening devices above the perforated disc, either in the form of tilt pins or in the form of mounting brackets that are open at the top. The tilting pins consist of a base in the form of a bolt with a cylindrical cross-section, aligned at right angles to the tube of the scaffolding post. A vertical slot is provided at its end facing away from the tube. The cylinder sections adjoining the slot are each penetrated by a bore in which a bolt is arranged. A tilting element is rotatably arranged on the bolt and is arranged to be pointed at its end hanging down due to the force of gravity. The upwardly open mounting brackets, which can be provided as an alternative, are each made from a mounting pin which is welded to the tube at an acute angle. Each mounting bracket therefore has a wedge-shaped design on its side facing the floor. On its side facing away from the floor, a receiving opening is formed, which results from the distance between the free end of the receiving pin and the pipe. Adjacent to the receiving opening, the receiving pin is bent over approximately at right angles to the tube of the scaffolding post. The two alternative fastening devices enable the struts forming a railing to be mounted from a secured position. This is ensured by the fact that the struts forming the railing can be threaded onto the receiving pins from the secured position. When using the mounting bracket, a through opening provided at the free end of the strut forming the railing of the strut forming the railing must be inserted into the said receiving opening and then threaded onto the receiving pin. The precise method with which a leading assembly of the railing struts is carried out when this scaffolding post is used is not disclosed. The upwardly open mounting brackets provided in this publication could theoretically - contrary to the teaching there using the handrail devices disclosed there - hang in other handrail devices, namely those handrail devices which are designed with at least one handrail rod or as a handrail rod, the handrail rod ends of which one Have fastening or suspension recess, the side surfaces extending away from one another and downward is open and which could be placed on the wedge-shaped formation of one of the mounting brackets or could be hung there, but these railing devices would then not be secured against unintentional lifting out of the mounting brackets which are open at the top. This scaffolding post has the features a) to f), partially h), k) and m) to o) of claim 1.

Another similar single vertical support for building a collapsible facade scaffolding and a method for assembling and dismantling the collapsible facade scaffolding are from FIG WO 98/07934 A known. Two special fastening means for railing elements, for example railing rods, are fastened to this vertical support above a single rosette provided for a base plate at a longitudinal distance from one another, which has openings for hanging the base plates. This vertical support has an effective total length which is approximately 2 m. The special fastening means for the balusters are extension pieces extending essentially perpendicular to the vertical support, two alternatives of extension pieces being disclosed. In the first alternative, each extension piece has two projections extending away from one another on its upper and lower sides, offset from one another. Each handrail has two equal handrail ends extending in opposite directions away from one another. Each end of the handrail is designed as a continuously circumferential tab which has a rectangular opening. The opening is designed as an elongated hole which, viewed in a direction parallel to the longitudinal axis of the balusters, has a length and a width perpendicular thereto with a transverse dimension that is smaller than the length of the opening. The transverse dimension of the opening is chosen so that the handrail can be threaded onto the respective extension piece with alternating pivoting movements. In the second alternative, each extension piece is formed by two sections arranged one above the other, one section having two projections extending in the direction of the other section and the other section having two recesses aligned with the projections. For threading a handrail end this is threaded with its tab also with alternating swivel movements over the lower part. To erect a facade scaffolding, the fitter initially stands on a floor slab of a first floor. The fitter is secured by at least one railing element which is releasably coupled to fastening means from vertical supports assigned to the first floor. After attaching another vertical support to the lower vertical support via a plug-in connection, the fitter hangs another railing element with one of its ends at a fastening position provided for a fastening element of the further vertical support attached to the lower vertical support. After this further railing element has been pivotably coupled at its other end to another vertical support relative to this, the further railing element is pivoted upwards together with said further vertical support by the fitter standing on the base plate of the lower floor, the while holding the further vertical support in his hand, whereupon said further vertical support is plugged onto a further vertical support that has already been set up underneath. In this installation position, the further railing element for the second floor above the first floor is consequently already erected before the further floor plate required for the second floor was attached. After attaching the further floor plate for the second floor, this can be entered by the fitter for the first time. At this point in time, the said further railing element is already mounted leading, so that there is already a side protection for the fitter when he steps on the further floor slab. Although this scaffold post allows an advantageous assembly of a leading railing from a secured position, the railing can only be slipped onto the extension pieces at an angle from below, ie from the scaffolding level below, by placing the railing at an angle of less than 90 degrees is attached to the extension piece from below to the longitudinal axis of the scaffolding standards. A horizontal attachment of railings from the same scaffolding level is not possible with these constructions. This scaffolding post has the features a) to g) of claim 1.

From the EP 2 503 075 A1 a scaffolding with at least two H-shaped vertical frames has become known. Each of the H-shaped vertical frames consists of supports made up of two tubes. The two pipes are connected to one another by a traverse that is welded to the pipes. The vertical frame has fastening devices that are used to arrange rods that serve as fall protection. Two of the fastening devices are attached to each pipe above the cross-member. Each of these fastening devices is designed as an upwardly open receiving bracket. Each mounting bracket is made with a pin that is bent twice at essentially right angles. On the side facing away from the floor, a receiving opening is formed between the pin and the tube. Adjacent to the receiving opening, the pin is bent over approximately at right angles, so that a substantially vertical section results. A support section is formed at right angles to this section, which is aligned at right angles to the pipe and which is welded to the pipe. This fastening device is also used to arrange rods that form the railing and thus a fall protection. The rods have flat pieces at their ends, in each of which through holes are arranged. To attach the fall protection from a secured position, the rods forming the fall protection are hung in the fastening position by the scaffolding erector from the hatch provided in a covering on a staircase. This is done by inserting the pin of the mounting bracket into the through hole of the rod. The other end of the rod is then attached to the vertical frame in the area of the opening hatch in the same way. This assembly secures the area provided with the hatch between the vertical frames on the upper floor, so that the scaffold builder can access the scaffolding floors in this secured area of this upper floor. To further create the fall protection, it is necessary to attach the handrails in the next scaffolding bay between adjacent vertical frames, in which scaffolding decks have already been attached from below. In order to prevent the scaffolding erector from entering this scaffolding bay, which is still unsecured against falling, before a fall protection in the form of a handrail is installed there as well a releasably locked cross brace is provided, which forms a barrier for the scaffold builder when the scaffolding continues to be built. This is intended to encourage the scaffold builder to hang the handrail for the next scaffolding bay from the already secured position in front of the cross brace forming the barrier onto the fastening devices of the vertical supports of the vertical frames of the neighboring scaffolding bay. This method of assembling a leading handrail is time-consuming and energy-consuming for the scaffold builder and is therefore not very practical. While each vertical frame of this scaffolding contains vertical supports, none of these supports is a single support. Viewed in a detached form from the H-shaped vertical frame, one of the supports has the features a), b), partly d), e) to g), partly h), i), k), m) and o) of the claim 1 on.

A similar H-shaped vertical frame for tubular scaffolding is from the publication DE 10 2008 005 813 A1 known. From this, too, a vertical frame has already become known, which has a fastening device which, from a secured position, enables the advanced assembly of guardrail poles to prevent falls. However, this vertical frame is not able to prevent the scaffold builder from entering the scaffolding floor of a scaffolding bay that has not yet been provided with fall protection. In this respect, the method used there for an early installation of the fall protection does not meet the high safety requirements. Incidentally, the method already described there for the early installation of the fall protection devices is correspondingly complex and impractical. Although this vertical frame also contains vertical supports, neither of these supports is a single support. Viewed in a detached form from the H-shaped vertical frame, one of the supports has the features a), b), partially d), e), partially h), i), k), m), and o) of claim 1 .

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. With this scaffolding frame there are two parallel Vertical supports are rigidly connected to one another in the region of their upper support ends at fastening positions provided at the same height via a single transverse arm extending perpendicular to the vertical supports. At the respective fastening position, a single perforated disk is fastened to each support by welding and is provided with openings. The openings are used to wedge bar elements provided with so-called connection heads to the vertical supports. Longitudinal bars and cross bars are usually used as bar elements. At its fastening ends extending away from one another, the transverse arm has a connection head with an insertion slot, via which the respective connection head is plugged onto the respective perforated disk and welded there and to the respective vertical support. Two railing fastening devices are attached to one of the two vertical supports below the perforated disk at a longitudinal distance from one another, a first railing fastening device of the railing fastening devices being fastened just below the longitudinal center of the associated vertical support, and a second railing fastening device of the railing fastening devices is fastened approximately in the middle between the first railing fastening device and the lower 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 bracket is a U-shaped bracket. A through opening in the form of a vertical receiving slot, which extends parallel to the longitudinal axis of the support, is formed between the bracket wall parts of the bracket and the outer wall of the support. The locking lever can be pivoted from an open position into a locking position. The railing devices in the form of handrails can be installed from the same scaffolding level as well as, if necessary, from a scaffolding level or floor below, in order to create a leading railing. For this purpose, the respective handrail rod can be suspended or threaded into the bracket designed as a bracket from below, in particular obliquely from below, preferably in its locked position located, so closed locking lever. For this purpose, the handrail rod with part of a handrail end of its handrail ends is inserted into the vertical receiving slot, placed or hung on a horizontal support surface of a support element of the holder and then pivoted upwards into a horizontal installation position. This scaffolding frame also contains vertical supports, but neither of these supports is a single support. However, this scaffolding frame with its special railing fastening devices has a number of advantages over other railing fastening devices of other scaffolding frames or even individual scaffolding posts. There are particularly advantageous possibilities for securing or locking the railing device and / or for assembling and / or dismantling the railing device and for a particularly stable construction. A connection arrangement consisting of this scaffolding assembly frame and a railing device detachably attached to its special railing fastening device is particularly easy and inexpensive to manufacture, can be assembled and dismantled particularly easily and quickly, offers particularly advantageous options for installing and removing the railing device from the same scaffolding position from as well as from below as a leading railing and enables the railing device to be expanded without the need to remove an adjacent railing device. Viewed in a form detached from the U-shaped scaffolding frame, one of the two supports has features a) to c) and e) to v) of claim 1.

In the parallel US 2010/0089697 A1 the applicant is illustrated and described with the aid of additional figures how the construction of a leading railing can take place. In the context of this, an alternative exemplary 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 region of their longitudinal center at fastening positions provided at the same height via a single transverse arm extending perpendicular to the vertical supports. At the respective fastening position, a single perforated disk is fastened to each support by welding, which is provided with openings. On each of the two vertical supports, two railing fastening devices are fastened above the perforated disk at a longitudinal distance from one another, with a first railing fastening device of the railing fastening devices being fastened approximately in the longitudinal center between the perforated disk and the upper end of the support of the associated vertical support. and wherein the second railing fastening device of the railing fastening devices is fastened in the region of the upper column end of this vertical column. The brackets and locking levers are designed in the same way as already described and shown in the first exemplary embodiment of a scaffolding frame. However, it is also possible that instead of these H-shaped scaffolding frames, other H-shaped scaffolding frames are used, in which only one vertical support of the two vertical supports rigidly connected to one another by means of a corresponding transverse arm can be provided with at least one identical railing fastening device. but can preferably also be provided with two identical railing fastening devices. To set up a leading railing, the scaffold erector must manually set the H-shaped scaffolding frame together with a railing device detachably attached to it upwards. It has been shown, however, that this is not possible for the scaffold builder or only with great effort and is associated with corresponding safety risks. Viewed in a form detached from the H-shaped scaffolding frame, one of the two supports has features a) to v).

Facade scaffolding (system scaffolding) is constructed from the vertical frames and scaffolding assembly frames mentioned above. Such facade scaffolding is mainly used as work and protective scaffolding for the safe processing of facades or as protective scaffolding that prevents people or material from falling. However, the above-mentioned vertical frames and scaffolding frames are too heavy for a scaffold builder to work with them without risks to the health of the scaffolders and without further safety risks to set releasably hinged railing device from a lower floor or from the ground to form a leading railing in the next higher floor.

From the U.S. 3,656,580 A Cross members and cross member elements for a modular framework have become known which, at at least one of their ends, disclose a connection body with a wedge-shaped widening guide pin and a fastening wedge that can be placed on its rear contact surface, by means of which the respective cross member or the respective cross member element is attached to one of several brackets of a scaffolding post can be releasably clamped. The brackets are vertical sockets for vertical insertion of the respective guide pin. These sockets do not allow the guide pins to be inserted horizontally. The individual scaffolding posts have the features a), b), partially d), e) to g), k) (detached) and m) of claim 1.

Similar connection nodes of a connection arrangement of a module frame are from AU 518 442 B2 known. These have the same disadvantages. The individual scaffolding standards have the features a), b), partially d), e) to g) and k) (detached), m) and u) to x) of claim 1.

For many decades, the applicant has been selling a pioneering modular scaffolding system in large numbers, which has become known as "Layher Allround Scaffolding". Such modular scaffolds are mainly used as surface or space scaffolding, for example in industry as work and protective scaffolding. But they can also be used as facade scaffolding. With this modular scaffolding, the standard axes of the individual scaffolding standards must be set up parallel to one another at special system axis spacings. A large number of scaffolding bars in different system lengths are available for this purpose. These scaffold bars have so-called connection heads at their bar ends, each with an upper head part and a lower head part and with a slot arranged between these to the horizontal Attachment to perforated disks of the scaffolding standards are provided. The scaffold bars can be releasably secured to the scaffold posts by clamping by means of the connection heads attached to their two bar ends pointing away from each other by means of a wedge that can be plugged or inserted through a passage opening of the passage openings of the respective assigned perforated disk. These modular scaffolds are system scaffolds in which the perforated disks are welded to the scaffold posts at regular intervals, preferably in a grid dimension of 50 centimeters. The perforated disks are used to releasably attach other scaffolding components such as bars, diagonals, consoles or other scaffolding components. Certain of these bars can be installed as railings. Such scaffolding standards are for example in the DE 10 2011 001 796 A1 or in the parallel WO 2012 / 136198A1 disclosed. The perforated disks usually have eight through holes, which are each arranged offset from one another at a circumferential angle of 45 degrees. Such perforated disks are for example in the DE 200 12 598 U1 or in the parallel WO 02/06610 A1 disclosed by the applicant. These individual scaffolding posts reveal features a) to g) of claim 1. If facade scaffolding is to be built from these individual scaffolding components, it is desirable if, for safety reasons, they are built with a leading railing so that rope protection is no longer necessary.

It is an object of the invention to provide a connection arrangement comprising a single first scaffolding post for a facade scaffolding or a facade scaffolding, which is releasably connected to a railing device, which is formed with at least one railing rod or as a handrail rod that extends in opposite directions from one another having away-pointing handrail rod ends each having a handrail support part with a recess for hanging in or for placing on a support part of a holder of the individual first scaffolding post attached to the individual first scaffolding post, the respective recess to side surfaces of the respective one extending away from one another The end of the handrail and open at the bottom, and wherein the handrail is attached to the bracket of the individual first Scaffolding post hanging freely downward and pivotable upward relative to the individual first scaffolding post before the handrail is transferred upwards into its horizontal installation position, and the handrail not only in a free, vertical downward hanging on the bracket and in a vertical inclination during an upward pivoting for the purpose of transferring into a horizontal installation position, in particular as a leading railing, as well as in the horizontal installation position, but also during its dismantling, in which its free second handrail end starting from the horizontal installation position or starting from the or an inclined position is released, is always hung secured against falling, and with the help of the individual first scaffolding post and the railing device, a facade scaffolding can be assembled and dismantled particularly easily, quickly and particularly safely with a leading railing. At the same time, while maintaining the advantages of the above prior art, its disadvantages are to be avoided.

This object is achieved by the features of claim 1.

The handrail bar 21.1 is made from a round tube which is shaped at its two tube ends to form a flattened handrail bar end 27.1, 27.2. Each flattened handrail end 27.1, 27.2 has flat side surfaces 28.1, 28.2 which extend parallel to one another and away from one another in opposite directions. The handrail 24; 24.1, 24.2 has a flattened first handrail end 28.1 and a flattened second handrail end 28.2, which extend away from one another in opposite directions parallel to the longitudinal axis 29 of the handrail. The first handrail end 28.1 and the second handrail end 28.2 are designed in the same way. The handrail 24; 24. Since the first and the second handrail end 28.1, 28.2 of each handrail 24; 24.1, 24.2 are designed in the same way, only one of these handrail ends is described in more detail below with reference to the first handrail end 28.1:

The first handrail rod end 28.1 has, in the horizontal installation position 53 of the first handrail rod 24.1 on the underside 36, a first recess 83 which leads to the side surfaces 28.1, 28.2 and downward 84 is open. The first recess 83 is delimited by recess support surfaces 86.2, 86.3, 97, 99, 102, 104 of a handrail end support part 71.1 for resting on the horizontal support surface 64 of the bracket contact part 60 of the bracket 55 of the scaffolding post 21.1. The first recess 83, viewed in the direction of the free end 88.1 of the first handrail end 28.1, is delimited by a concave wall part 90 of a suspension hook 89. This wall part forms a hook base 90 of the suspension hook 89. The hook base 90 is designed to be circular-cylindrical with a concave radius 91. The radius is preferably 4 mm. The radius 91 of the hook base 90 spans a diameter, preferably about 8 mm. This diameter is slightly larger than the wall thickness 74 of the bracket system part 60 and is less than twice the wall thickness 74 of the bracket system part 60. The suspension hook 89 encloses a first recess part 92.1 of the first recess 83 with its rearward direction 93 or in the direction of the other or second handrail end 27.2 extending free hook end 94. The free hook end 94 of the suspension hook 89 has hook end support surfaces 86.3, each of which is recess support surfaces of the first recess 83 delimiting recess support surfaces of the handrail end -Support part 71.1 of the first handrail 24.1 is. The hook end support surfaces 86.3 are flat and are arranged at an angle 96, preferably about 30 degrees, to the handrail end longitudinal axis 48 and to the handrail longitudinal axis 29 of the first handrail 24.1. The recess support surfaces 86.2 of the hook base 90 merge continuously, that is to say continuously, without kinks and steps or tangentially, into the hook end support surfaces 86.3 of the free hook end 94 of the suspension hook 89. In a direction pointing away from the free hook end 94, the recess support surfaces 86.2 of the hook base 90 continuously merge into a flat first support surface 97, which extends parallel to the handrail end longitudinal axis 48 and parallel to the handrail longitudinal axis 29 of the first handrail 24.1. The first support surface 97 merges at a first longitudinal distance 98 from the hook base 90 into a first support surface 99 of a first support wall 100, which is perpendicular thereto. The first longitudinal distance 98 is preferably approximately 22 mm. the First support wall 100 has a first support wall height 101, preferably 9 mm. The first support wall 100, viewed in a direction away from the hook base 90 or from the free hook end 94 and parallel to the handrail end longitudinal axis 48 or to the handrail longitudinal axis 29, merges into a second bearing surface 102 of a second support wall 103, which extends parallel to the handrail end longitudinal axis 48 or parallel to the handrail longitudinal axis 29. The second support surface 102 in turn merges into a second support surface 104 of a concave wall part 105 which is designed with a radius 106. This radius 106 is preferably approximately 10 mm. At a second longitudinal distance 107 from the free hook end 94 of the suspension hook 89, this wall part 105 again merges into a rear, lower outer end face 108 of the first handrail end 27.1, which extends parallel to the handrail end longitudinal axis 48 or parallel to the handrail longitudinal axis 29 extends. The second longitudinal distance 107 is preferably approximately 52 mm. Said rear, lower outer end face 112 is aligned with a lower hook outer end face 112 delimiting the free hook end 94. The hook outer end face 112 has a preferably approximately 15 mm from the first support surface 97 extending parallel to it. first transverse distance 109. The free hook end 94 of the suspension hook 89 has a third longitudinal distance 110 from the free end 88.1 of the first handrail end 27.1. The third longitudinal distance 110 is preferably approximately 21 mm. The second support surface 102 of the second support wall 103 has a second transverse distance 111 from the rear, lower outer end face 108, which corresponds to a height or depth 113 of a second recess part 92.2 of the first recess 83. This height or depth 113 is preferably approximately 6 mm.

In the Figures 10 to 14 the facade scaffolding 20 is shown in a second assembly or dismantling phase, in which two balusters 24.1, 24.2 each in the area of their two baluster ends 27.1, 27.2 on each of a bracket 55 of the associated balustrade fastening device 50.1, 50.2 and the scaffold post shown approximately in the center of the picture 21.1 as well as the front right further scaffolding post 21.1 shown are suspended, the balusters 24.1, 24.2 each extending in a vertical inclined position 130 approximately parallel to one another at an angle 131 to the horizontal 132.

The first recess 83 has in its first recess part 92.1 delimited by the hook base 90 and by the first support surface 97 as well as by the first support surface 99, in a direction parallel to the railing rod end longitudinal axis 48 and in a direction parallel to the railing rod longitudinal axis 29 considered, a minimum first recess length corresponding to the first longitudinal distance 98. The minimum first recess length 98 is accordingly preferably approximately 22 mm. The minimum recess length 98 of the first recess 83 is greater than the height 72 of the bracket contact part 60. The free hook end 94 of the suspension hook 89 has a fourth longitudinal distance 114 from the first support surface 99 of the first support wall 100. The fourth longitudinal distance 114 is preferably approximately 14 mm. By means of the above measures it can be achieved that the first handrail rod 24.1, which is suspended by means of its suspension hook 89 on the bracket contact part 60 of the bracket 55 of the individual first scaffolding post 21.1, can hang freely vertically, at least approximately vertically, downwards in a first assembly or disassembly phase (please refer Figures 8 and 9 ).

The fourth longitudinal spacing 114 is greater than the wall thickness 74 of the bracket contact part 60 in the area of the horizontal bearing surface 64, so that the handrail 24.1 can lock there in its horizontal installation position 53 in a form-fitting manner. The fourth longitudinal distance 114, which can also be referred to as the support surface distance, is preferably about 2 to 3 times the wall thickness 74 of the bracket contact part 60 in the area of its support surface 64 Railing rod 24.1, in any case, can be hung reliably and securely in the area of its two railing rod ends 27.1, 27.2 in each of a bracket 55 of the scaffolding posts 21.1 according to the invention in the horizontal installation or use position 53.

The first handrail end 27.1, viewed in a transverse direction 115 perpendicular to the first handrail end longitudinal axis 48 or to the handrail longitudinal axis 29, has a maximum width or maximum height 116. This width or height 116 is preferably approximately 50 mm. This width or height 116 corresponds to an end face distance between the hook outer end face 112 of the free hook end 94 and a front, upper outer end face 117 of the first handrail end 27.1 which points away in an opposite direction and extends parallel thereto.

The front, upper outer end face 117 merges in the direction of the other or second handrail end 27.2 at a fifth longitudinal distance 118 from the free end 88.1 of the first handrail end 27.2 into an upper, second recess 120 of the first handrail end 27.1. This second recess 120 is open to the side surfaces 28.1, 28.2 of the first handrail 27.1 pointing away from one another and at the top 85. The fifth longitudinal spacing 118 is preferably approximately 27 mm. The front, upper outer end face 117 initially merges into a first inclined face 122. This forms an angle 123 with the first handrail end longitudinal axis 48 or with the handrail longitudinal axis 29. This angle 123 is preferably approximately 18 degrees. The first inclined surface 122 merges, in the direction of the other or second handrail end 27. 2, into a concave surface 125 rounded with a radius 124, which in turn merges into a second inclined surface 126. This second inclined surface 126 forms an angle 127 with the first inclined surface 122. This angle 127 is preferably greater than 90 degrees. In particular, the angle 127 is approximately 102 degrees. This second inclined surface 126 merges in the direction of the other or second handrail end 27.2 with a convex rounded shape into a rear, upper outer end face 128 of the first handrail end 27.1. This is aligned with the front, upper outer end face 117 of the first handrail end 27.1. The upper, second recess 120 has a recess depth or height 129 that is preferably approximately 14 mm.

As in particular in the Figures 10 and 13th shown, can in a second assembly or dismantling phase, in which at least one handrail 24.1, 24.2 in the area of its two handrail ends 27.1, 27.2 on each of a bracket 55 of the associated railing fastening device 50.1, 50.2 each of a scaffold post 21.1, 21.2 is or is hung , but preferably two balusters 24.1, 24.2 each in the area of their baluster ends 27.1, 27.2 on a bracket 55 of the associated balustrade fastening device 50.1, 50.2 each of a scaffold post 21.1, 21.1 of adjacent scaffold posts 21.1, 21.1 are or will be suspended. A first scaffolding post 21.1 is in its installed and use position, in which it is attached to the short scaffolding post 21.1 located below, while an adjacent second scaffolding post 21.1 is either not yet attached to the associated short scaffolding post 21.2 in an assembly phase or in a Disassembly phase has already been released from the associated short scaffolding post 21.2 and then placed with its lower post end 41.1 on a scaffolding floor 23 of the lower floor 54.1. In this second assembly or disassembly phase, the at least one handrail post 24.1, 24.2 or the two handrail posts 24.1, 24.2 are arranged in a vertical inclination 130 at an angle 131 to the horizontal 132. The hanging situation shown in this inclined position 130 in the area of a bracket 55 of the first scaffolding post 21.1 is shown in FIG Figure 11 illustrated. There it can be clearly seen how, in this inclined position 130, a part of the first handrail end 24.1 of the handrail 24.1 which contains the suspension hook 89 extends through the through opening 70 of the holder 55, which is designed as a vertical receiving slot, and the bracket contact part 60 of the bracket 55 at least partially is received in the first recess 83 of the first handrail end 27.1 and the free hook end 94 of the suspension hook 89 engages behind the bracket contact part 60 of the bracket 55. In the angular position of the handrail 24.1 shown, the hook end support surfaces 86.3 of the free hook end 94 of the suspension hook 89 extend approximately parallel to that in FIG Figure 11 Side surface 75.1 of the bracket contact part 60 of the bracket 55, shown on the right.

As from the Figures 12 and 13th can be seen, the railing post longitudinal axis 29 includes each railing post 24; 24.2, 24.2 form an angle 131 with the imaginary horizontal 132 formed perpendicular to the shaft longitudinal axes 40.1. This angle 131 is about 20 degrees here. In this intermediate assembly or disassembly position, the upper, second recess 120 of the second handrail end 27.2 of the respective handrail 24; 24 Figure 13 ).
