Description

SINGLE SCAFFOLDING STICK

The invention relates to a single scaffold post made of metal, in particular steel, for a facade scaffold or a facade scaffold.

EP 1 91 1 907 A1 by the applicant shows a vertical frame element with a first handle, to which a single perforated disk is attached by welding in the region of its upper handle end. A first connection head of a transverse arm designed with a round tube, which extends perpendicularly away from the first stem, is plugged onto the perforated disc and has a slot. The first connection head formed on the round tube of the cross arm is welded to the perforated disc of the first arm and to its outer circumference. At its end pointing away from the first stem, the cross arm has a separate, second connection head which is welded to the round tube. The second connection head also has a slip-on slot with which it is plugged onto a perforated disk of a second handle and is there again detachably wedged by means of a wedge. The perforated disc of the second stem is attached to the second scaffold stem below the longitudinal center. 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 lateral frame which is resistant to bending and torsion. Two railing fastening devices in the form of bolts are fastened to the second arm above the perforated disk, which are of identical design and which extend perpendicularly to the longitudinal axis of the scaffold arm. The second stem is on a short stem, forming a lateral vertical frame for connecting 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 the said second handle, railing devices, in particular those which are designed with at least one railing rod or as a railing rod, the railing rod ends of which have a fastening or hanging recess which face away from one another. stretching side surfaces and is open at the bottom, not to be secured against falling without additional components. Said separate, second stem has the features a) to g) of claim 1.

A similar scaffold frame with two scaffold posts has become known from EP 1 672 140 A2. This scaffold frame also contains a single, second scaffold post. A single perforated disc is also attached to this second scaffold post below its longitudinal center. This second scaffold post is provided with vertical bushings and with horizontal bushings, on each of which a hook-shaped end of a diagonal or side scaffolding element (not described in more detail) can be hung. A first horizontal bushing is fastened close below the perforated disc and a second horizontal bushing appears to be fastened above the perforated disc at a distance from the lower end of the stem which, measured from the figures, corresponds to approximately 80% of the stem length. A first vertical bush appears to be attached in the area of the upper stem end. A second vertical bush appears to be attached at a height close to the longitudinal center between the top of the stem and the perforated disc. Although one said frame element, not described in more detail, can be hooked onto the respective bushings, it is unclear how. This second stand has the features a) to d) and h) to m) of claim 1.

A similar, similar scaffold post has become known from EP 2 083 132 A2 in the form of a scaffold stand for system scaffolds for scaffolding buildings. This in turn bears one close below its longitudinal center Perforated disc and has two fastening devices above the perforated disc, either in the form of tilting 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, which is aligned at right angles to the tube of the scaffold post. A vertical slot is provided at its end facing away from the tube. The cylinder sections adjacent to the slot are each penetrated by a hole in which a bolt is arranged. A pivoting element is rotatably arranged on the bolt, which is arranged at a point at its gravitationally hanging end. The alternatively provided, upwardly open mounting brackets 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 bottom, a receiving opening is formed, which results from the distance between the free end of the receiving pin and the tube. Adjacent to the receiving opening, the receiving pin is bent approximately at a right angle to the tube of the scaffold stem. The two alternative fastening devices enable the struts forming a railing to be assembled from a secured position. This is guaranteed by the fact that the struts forming the railing can be threaded onto the mounting 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 said mounting opening and then threaded onto the mounting pin. The exact method with which this scaffold post is used to perform a premature assembly of the railing struts is not disclosed. In theory, contrary to the teaching there using the railing devices disclosed therein, other railing devices, namely those railing devices which are designed with at least one handrail rod or as a handrail rod, could theoretically be hung in with the holding brackets open at the top, contrary to the teaching there - The railing rod ends have a fastening or hanging recess, the side surfaces extending away from one another and downwards is open and which could be placed on or attached to the wedge-shaped design of one of the holding brackets, but these railing devices would then not be secured against unintentional lifting out of the holding brackets which are open at the top. This scaffold stem has the features a) to f), partially h), k) and m) to o) of claim 1.

WO 98/07934 A discloses an individual vertical support, again similar, for assembling a dismantled facade scaffold and a method for assembling or dismantling the dismantled facade scaffold. Two special fastening means for railing elements, for example railing rods, are fastened to this vertical support at a longitudinal distance from one another above a single rosette provided for a base plate, which has openings for hanging the base plates. This vertical support has an effective total length that is approximately 2 m. The special fastening means for the balusters are extension pieces which extend essentially perpendicular to the vertical support, two alternatives of attachment pieces being disclosed. In the first alternative, each end piece has two projections extending away from one another on its upper and lower sides, offset from one another. Each railing rod has two identical railing rod ends that extend away from one another in opposite directions. Each railing rod end is designed as a continuous, 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 railing rod, has a length and perpendicular thereto a width with a transverse dimension which is smaller than the length of the opening. The transverse dimension of the opening is selected so that the railing rod can be threaded onto the respective extension piece by performing alternating pivoting movements. In the second alternative, each extension 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 railing rod end this is also threaded with its tab under the execution of alternating pivoting movements over the lower section. To set up a facade scaffold, the fitter initially stands on a floor slab on a first floor. In this case, the fitter is secured by at least one railing element, which is detachably coupled to vertical supports assigned to fastening means from the first floor. After another vertical support has been plugged onto the lower vertical support by means of a plug-in connection, the fitter hangs another railing element with one of its ends at a fastening position of a fastening element of the further vertical support which is attached to the lower vertical support. After this further railing element has been pivotally coupled at its other end to a further vertical support relative to this, the further railing element is pivoted upwards together with said vertical support with the aid of said further vertical support, specifically from that on the base plate of the Installer standing on the lower floor, holding the additional vertical support in his hand, whereupon the said further vertical support is plugged onto the additional vertical support already set up below. In this installation position, the additional railing element for the second floor above the first floor is therefore already erected before the additional floor slab required for the second floor has been attached. After installing the additional floor slab for the second floor, the installer can enter it for the first time. At this point in time, said further railing element is already premounted, so that the fitter already has side protection when he enters the further base plate. Although this scaffold post enables an advantageous assembly of a leading railing from a secured position, the railings can only be attached to the extension pieces at an angle from below, ie from the scaffolding position underneath, by the railing at an angle of less than 90 degrees to the longitudinal axis of the scaffold stems is attached to the extension from below. Horizontal installation of railings from the same scaffolding position is not possible with these constructions. This scaffold stem has the features a) to g) of claim 1. From 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 which are formed from two tubes. The two pipes are connected to each other by a crossbar that is welded to the pipes. The vertical frame has fastening devices which serve to arrange rods which serve as fall protection devices. Two of the fastening devices are fastened to each tube above the traverse. 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 essentially at right angles. On the side facing away from the bottom, a receiving opening is formed between the pin and the tube. Adjacent to the receiving opening, the pin is bent approximately at right angles, so that there is a substantially vertical section. A support section is formed at right angles to this section, which is oriented at right angles to the pipe and which is welded to the pipe. This fastening device also serves to arrange rods which form the railing and thus a fall protection device. The rods have flat pieces at their ends, in each of which through holes are arranged. To attach the fall arrest device from a secured position, the rods that form the fall arrest device are hung on the fastening position by the scaffolding engineer, from which the hatch provided with a covering stands 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 same way in the area of the opening hatch. With this assembly, the area provided with the hatch is secured between the vertical frames on the upper floor, so that the scaffolding builder can enter the scaffolding floors in this secured area of this upper floor. In order to further create the fall protection, it is necessary to attach the railing rods in the next scaffolding field between adjacent vertical frames, in which scaffolding floors have already been attached from below. To prevent the scaffolders from entering this scaffold bay, which is still unsecured against falling, before a fall protection in the form of a railing rod is also installed there a releasably locked cross strut is provided, which forms a barrier for the scaffolders in the further construction of the scaffolding. This is intended to encourage the scaffolding builder to hang the railing bar for the next scaffolding field from the already secured position in front of the cross strut forming the barrier, on the fastening devices of the vertical supports of the vertical frame of the neighboring scaffolding field. This method of assembling a leading railing is time-consuming and forceful for the scaffolding engineer and therefore not very practical. Each vertical frame of this scaffolding contains vertical supports, but none of these supports is an individual support. When viewed from the H-shaped vertical frame, one of the supports has the features a), b), partially d), e) to g), partially h), i), k), m) and o) of the claim 1 on.

A similar H-shaped vertical frame for tubular scaffolding has become known from the publication DE 10 2008 005 813 A1. From this, too, a vertical frame has already become known, which has a fastening device, which enables a premature assembly of crash-proof railing rods from a secured position. However, this vertical frame is unable to prevent the scaffolder from entering the scaffolding floor of a scaffold bay that has not yet been provided with fall protection. In this respect, the procedure used there for premature installation of the fall arrest system does not meet the high safety requirements. Incidentally, the method already described there for the premature installation of the fall protection devices is correspondingly complex and not very practical. This vertical frame also contains vertical supports, but none of these supports is a single support. When viewed 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 the claim 1 on.

From EP 1 983 129 A2 and WO 2008/128500 A2 from the applicant, a rigid U-shaped scaffolding frame for a facade scaffold or a facade scaffold has become known. There are two parallel ones on this scaffold frame 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 transverse arm extending perpendicular to the vertical supports. At the respective fastening position, a single perforated disk is welded to each support and is provided with openings. The breakthroughs are used to wedge bar elements with so-called connection heads onto the vertical supports. Longitudinal bars and cross bars are usually used as bar elements. At its fastening ends, which extend away from one another, the cross arm each 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 fastened to one of the two vertical supports below the perforated disc 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 assigned vertical support , and wherein a second railing fastening device of the railing fastening devices is fastened approximately midway 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 relative to the holder about a pivot axis. 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 is formed between the bracket wall parts of the bracket and the outer wall of the support and 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 railing rods can be installed both from the same scaffolding level and, if necessary, to create a leading railing, from a scaffolding level or floor underneath. For this purpose, the respective railing rod can be hung or threaded from below, in particular obliquely from below, into the bracket designed as a bracket, preferably with its locking mechanism position, i.e. closed locking lever. For this purpose, the railing rod is inserted or suspended with a part of a railing rod end of its railing rod ends into the vertical receiving slot on a horizontal support surface of a support element of the holder and then pivoted upwards into a horizontal installation position. This scaffold frame also contains vertical supports, but none of these supports is a single support. However, this scaffolding stand frame with its special railing fastening devices has a number of advantages compared to other railing fastening devices of other scaffolding frames or also individual scaffold posts. There are particularly advantageous possibilities for securing or locking the railing device and / or for assembling and / or disassembling the railing device and for a particularly stable construction. A connection arrangement consisting of this scaffolding frame and a railing device detachably attached to its special railing fastening device is particularly simple and inexpensive to manufacture, particularly simple and quick to assemble and dismantle, and offers particularly advantageous possibilities for installing and removing the Railing device both from the same scaffolding position and from below as a leading railing and enables the railing device to be removed without the need to remove an adjacent railing device. When viewed in a form detached from the U-shaped scaffolding frame, one of the two supports has the features a) to c) and e) to v) of claim 1.

In the applicant's parallel US 2010/0089697 A1, additional figures are used to illustrate and describe how a leading land can be built up. As part of this, an alternative exemplary embodiment of a scaffolding stand frame is also shown and described, which is a rigid H-shaped scaffold stand 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 transverse arm that extends perpendicular to the vertical supports. prevented. At the respective fastening position, a single perforated disc is also attached to each support by welding, which is provided with openings. On each of the two vertical supports, two railing fastening devices are fastened at a longitudinal distance from one another above the perforated disk, a first railing fastening device of the railing fastening devices being fastened approximately in the longitudinal center between the perforated disk and the upper support end of the associated vertical support and where the second railing fastening device of the railing fastening devices is fastened in the region of the upper support end of this vertical support. The brackets and locking levers are designed the same as already described and shown in the first embodiment of a scaffolding frame. It is also possible, however, 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 with at least one same railing frame - Fastening device can be provided, but preferably can also be provided with two identical railing fastening devices. To erect a leading railing, the scaffolding engineer must manually raise the H-shaped scaffolding frame together with a railing device that is detachably attached to it. However, it has been shown that this is not possible for the scaffolding builder, or is only possible with great effort, and is associated with the corresponding security risks. When viewed in a form detached from the H-shaped scaffolding frame, one of the two supports has the features a) to v).

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

From US 3,656,580 A, cross members and cross member elements for a modular scaffold have become known which, at at least one of their ends, disclose a connecting body with a guide pin widening downwards in a wedge shape and with a fastening wedge which can be placed on its rear contact surface, by means of which the respective cross member or the respective cross member element can be releasably clamped to one of a plurality of holders of a scaffold post. 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 stems 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 have become known from AU 518 442 B2. These have the same disadvantages. The individual scaffolding stems have the features a), b), partially d), e) to g) and k) (detached), m) and u) to x) of claim 1.

The applicant has been selling a pioneering modular scaffolding system in large quantities for many decades, which has become known as the “Layher all-round scaffolding”. Such modular scaffolds are mainly used as surface or room scaffolds, for example in industry as work and protective scaffolds. But they can also be used as facade scaffolding. With this modular scaffold, the stick axes of the individual scaffold stems are to be set up parallel to each other at special system center distances. For this purpose, a variety of scaffold bars are offered in different system lengths. These scaffold bolts have so-called connection heads at their bolt ends, each with an upper head part and a lower head part and with a slot arranged between them to the horizon tale are placed on perforated discs of the scaffold posts. The scaffold bolts can be releasably fixed to the scaffold posts by means of a connection wedge attached to their two mutually pointing bolt ends by means of a wedge which can be plugged or inserted into the scaffold posts through a through opening of the through openings of the respectively assigned perforated disk. These modular scaffolds are system scaffolds in which the perforated disks are welded onto the scaffold posts at regular intervals, preferably with a grid dimension of 50 centimeters. The perforated disks are used for the detachable fastening of other scaffolding components such as bolts, diagonals, brackets or other scaffolding components. Certain of these bars can be installed as railings. Scaffolding stems of this type are disclosed, for example, in DE 10 201 1 001 796 A1 or in parallel WO 2012/136198 A1. The perforated disks usually have eight through holes, which are each offset from one another at a circumferential angle of 45 degrees. Such perforated disks are disclosed, for example, in DE 200 12 598 U1 or in the applicant's parallel WO 02/06610 A1. These individual scaffolding posts disclose the features a) to g) of claim 1. If façade scaffolding is to be built from these individual scaffolding components, it is desirable if they are built with a leading railing for safety reasons so that rope protection is no longer necessary.

It is an object of the invention to provide a single first scaffold post for a facade scaffold or a facade scaffold which is releasably connected to a railing device which is designed with at least one railing rod or as a railing rod which is in the opposite direction - Has railing rod ends pointing away from one another, each of which has a railing rod support part with a recess for hanging in or for resting on a support part of a holder of the individual first scaffold arm fastened to the individual first scaffold arm, the respective recess facing each other away extending side surfaces of the respective railing rod end and is open at the bottom, and the railing rod hanging freely on the holder of the individual first scaffolding arm and can be pivoted upwards relative to the individual first scaffold arm before the railing rod is moved upwards into its horizontal installation position, and the railing rod not only with a free, vertical downward hanging on the holder and with a vertical inclination during one Swiveling upwards for the purpose of transferring to a horizontal installation position, in particular as a leading railing, as well as in the horizontal installation position, but also during its disassembly, in which its free second railing rod end starting from the horizontal installation position or starting from the or released from an inclined position, is always secured against falling, and with the help of the individual first scaffold post and the railing device, a facade scaffolding can be assembled and disassembled particularly easily, quickly and particularly safely with a leading railing. At the same time, the disadvantages of the above prior art are to be avoided while maintaining the advantages.

The free hook end 94 of the hooking hook 89 has a third longitudinal distance 110 from the free end 88.1 of the first railing rod 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 1 1 1 from the rear, lower outer end face 108, which corresponds to a height or depth 1 13 of a second recess part 92.2 of the first recess 83. This height or depth 1 13 is preferably approximately 6 mm.

FIGS. 10 to 14 show the facade scaffold 20 in a second assembly or disassembly phase, in which two guardrail rods 24.1, 24.2 each in the area of their respective two guardrail rod ends 27.1, 27.2 on a holder 55 of the associated guardrail fastening device 50.1, 50.2 both of the scaffold stick 21.1 shown in the middle of the picture and the one on the front right shown further scaffold post 21 .1 are suspended, the railing rods 24.1, 24.2 each extending approximately parallel to one another at an angle 131 to the horizontal 132 in a vertical inclined position 130.

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 and by the first support surface 99, in a direction parallel to the longitudinal axis 48 of the handrail rod and in a direction parallel to the longitudinal axis 29 of the handrail rod 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 hooking hook 89 is at a fourth longitudinal distance 114 from the first support surface 99 of the first support wall 100. The fourth longitudinal distance 1 14 is preferably approximately 14 mm. As a result of the above measures, the first railing rod 24.1 hanging by means of its hooking hook 89 on the bracket contact part 60 of the bracket 55 of the individual first scaffold post 21 .1 is freely vertical, at least approximately, in a first assembly or disassembly phase perpendicular, can hang down (see Figures 8 and 9).

The fourth longitudinal distance 1 14 is greater than the wall thickness 74 of the bracket contact part 60 in the region of the horizontal support surface 64, so that the railing rod 24.1 can snap there in a form-fitting manner in its horizontal installation position 53. The fourth longitudinal distance 114, which can also be referred to as the support surface distance, is preferably approximately 2 to 3 times the wall thickness 74 of the stirrup attachment part 60 in the area of its support surface 64. This allows manufacturing and in particular installation tolerances to be compensated for, so that it is set that the railing rod 24.1, in any case reliably and securely in the region of its two railing rod ends 27.1, 27.2, can be hung in a bracket 55 of the scaffolding posts 21 .1 according to the invention in the horizontal installation or use position 53. The first handrail rod end 27.1, viewed in a transverse direction 115 perpendicular to the first handrail rod longitudinal axis 48 or to the handrail rod 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 1 16 corresponds to an end face distance between the hook outer end face 1 12 of the free hook end 94 and a front, upper outer end face pointing away therefrom in an opposite direction and extending parallel thereto 1 17 of the first railing end 27.1.

The front, upper outer end face 11 17 merges towards the other or second handrail rod end 27.2 at a fifth longitudinal distance 118 from the free end 88.1 of the first handrail rod end 27.2 to an upper, second recess 120 of the first handrail rod end 27.1 , This second recess 120 is open to the mutually facing side surfaces 28.1, 28.2 of the first railing bar 27.1 and upwards 85. The fifth longitudinal distance 1 18 is preferably approximately 27 mm. In this case, the front, upper outer end face 11 first merges into a first inclined surface 122. This encloses an angle 123 with the first longitudinal axis 48 of the railing rod end or with the longitudinal axis 29 of the railing rod. This angle 123 is preferably approximately 18 degrees. The first inclined surface 122, in the direction of the other or second railing rod end 27.2, merges into a surface 125 which is rounded concavely with a radius 124 and 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 convexly in the direction of the other or second railing rod end 27.2 into a rear, upper outer end surface 128 of the first railing rod end 27.1. This is aligned with the front, upper outer end face 117 of the first railing rod end 27.1. The upper, second recess 120 has a recess depth or height 129, which is preferably approximately 14 mm.
