Abstract

The method involves fitting a support frame-suspending-device at the support frame (20) for suspending another support frame to be mounted. The support frame-suspending-device is supported or carried by the component on a component of the scaffold, particularly on an already mounted support frame (20.1). The other support frame is detachably supported or suspended on the support frame-suspending-device. An independent claim is included for a method for disassembling a scaffold.

Description

The invention relates to a method for mounting and a method for disassembling a rolling tower, which can also be referred to as a mobile work platform. Such a scaffold is or is usually constructed of vertical support frame, each having at least two stems and a plurality of connecting them rungs for raising and / or dismounting people and / or for hanging and / or laying or supporting scaffold floors, diagonal Contain connection elements and / or horizontal connection elements.

Such scaffoldings have become common knowledge for many years, for example, from the DE 43 06 732 A1 , Such scaffolds are usually constructed starting from two support frames, at the lower end of the handlebar lockable wheels or rollers are attached. Alternatively, the support frame can each be mounted on a moving beam, preferably by their stems are placed on or in matching vertical recordings that are fixed, possibly horizontally displaceable, connected to the respective moving beam, wherein in the region of the transverse ends of each driving bar at least two detectable Wheels or wheels are attached. The two lowest support frames are viewed perpendicular to their respective rungs, constructed in a support frame distance parallel to each other in each case in a vertical position or in the vertical. Between the support frame, a scaffold floor is releasably attached to the rungs, preferably with the help of so-called latching claws. It can also be a scaffold board. In this way you get a first layer or floor of the scaffold. Such Einrastklauen are for example from the DE 37 02 152 A1 and the DE 38 22 215 A1 known. They allow a secure setting of these latching jaws containing components, such as scaffold floors, diagonal and / or horizontal struts or rods to, in particular having a round cross-section, other struts or rods. The latching claws or the components equipped therewith can be attached to the struts or rods so as to be pivotable relative thereto.

To build other floors can be attached to the lower support frame more support frame, preferably plugged, wherein between each two of these further support frame another scaffold floor is releasably attached. Usually, each floor is stiffened by means of two diagonal struts, which are preferably arranged crosswise. For this purpose, these diagonals, preferably also with the aid of provided at the ends Einrastklauen, at two horizontally spaced in one or the support frame distance support frame, preferably on each one of their rungs, are releasably secured. The attachment of the diagonal is carried out in a lateral distance to the stems or near the stems of the support frame so that enough space remains for a person staying on a scaffold floor and thus also an advantageous stiffening of the scaffold is achieved.

Not only in the assembled state, but also in the construction or in the dismantling of such scaffolds, the safety of persons staying on the scaffolding floors plays an outstanding role. It must always be ensured that the persons staying on the scaffolding floors are safely protected against falling off the scaffold floors or from the mobile scaffold. Specifically, according to the Equipment and Product Safety Act (GPSG), it is stipulated and required that a product may only be placed on the market if it is designed so that the safety and health of users or third parties are not jeopardized if used as intended or foreseeably misused. In addition, according to the Operational Safety Ordinance (BetrSichV), the necessary measures for the safe provision and use of work equipment must be determined. Also in this respect, a safe assembly and disassembly of mobile work platforms or rolling stands must be guaranteed.

In order to avoid that a person on a scaffold floor is not secured against falling down during the construction or dismantling of the scaffold, a number of different measures have been taken according to the state of the art.

A first of these measures has become known in the English-speaking world under the name "3T Method" or "Through The Trap (Door)". According to be assembled or disassembled mobile scaffolds by the English company "Turner Access Ltd." under the name "Octo" and offered by the English company "SGB Group" under the name "Boss" and by the Irish company "Instant Upright" under the name "Span". In this case, the assembly or disassembly of the balusters is done in such a way that the fitter stands on a rung under a scaffolding floor arranged rung of a support frame and at the same time with his upper body through the closable with a flap access opening of the access scaffold floor in this position, the balusters at a sufficient distance above of the access ladder floor on the rungs of these access ladder floor upwards protruding parts of the support frame supporting this access floor floor mounted or dismounted. When dismantling the balusters, however, there is the problem that the Railing bars already have to be solved at their remote from the access opening of the access ladder floor end, while the fitter is still on the top level, that is still on the topmost access ladder floor. In any case, under the conditions mentioned above, this method leads to unacceptable safety risks, at least when dismantling the mobile scaffolds.

Another measure according to the prior art is to provide a so-called "leading" railing. Here, the handrails of the next higher floor to protect a person against falling from the next higher scaffold floor are mounted by the standing on the scaffold floor of a lower floor fitter. Such scaffolds to be mounted or dismounted are manufactured by the French company "COMABI" under the names "GENERIS" and "JUNIOR" ( FR 2 908 804 A ) and by the German company "Hymer AG" under the name "SC 80 comfort structure" become known ( DE 10 2007 011 777 A1 ).

The "COMABI" system uses a leading double railing in which a hip guard rail and a knee guard rail are integrated in a common railing facility. To mount the leading double railing is first from the ground or from the scaffold floor of a lower floor, a hinged attached to the double railing lifting-auxiliary rod of a transport layer in which this is clamped approximately parallel to the hip or back railing rod, in repositioned an actuation sheet in which the elevating-auxiliary rod projects downward from the double railing at an angle of about 70 to 80 degrees to the railing bars. Subsequently, this unit of double railing and lifting auxiliary rod is given by a mechanic up to a standing on the next higher scaffold floor of the next higher floor second mechanic. This second installer then hangs this unit via a hook attached to the other end of the double railing at one above the next higher scaffold floor attached rung of a support frame relative to this or this pivotally mounted a. Subsequently, the fitter pivots the suspended double railing upwards and hangs it over two, at the lower end, ie where the lifting auxiliary rod is clamped, attached hooks in a horizontal position on a further rung of another support frame, which in one of the length of the scaffold floor or the double railing corresponding horizontal distance from the first-mentioned support frame is mounted. Then the jamming of the lifting-auxiliary rod is solved on the double railing, so that after installation of the next higher scaffolding floor, which is to be secured with the previously mounted double railing, the lifting-auxiliary rod then when the fitter on the mounted top scaffold floor climbed up, again in a position parallel to the top scaffold pole of the double railing, can be clamped. Alternatively, said double guardrail and lift-and-off bar assembly may also be relocked by the second installer, whereupon the double guardrail can then be mounted by means of the lift-and-off bar, as previously described, to the next higher level to realize leading railings. The assembly and disassembly of this leading railing is relatively expensive and due to the fixed with each double railing lifting-auxiliary rod, the fitters always have to handle a correspondingly large weight during assembly and disassembly.

The measure or solution of a leading railing, as it uses the company Hymer, seems to solve this problem. Because there is used as a lifting-auxiliary rod a separate component, here in the form of an assembly / disassembly auxiliary rod, called "Hymer-Lifter", which therefore not firmly connected to the to be mounted or dismantled railing rod is. This assembly / disassembly auxiliary rod has at its actuating end a laterally open, C-shaped hook. For the purpose of mounting a scaffold rod already attached to a rung of the uppermost support frame by means of a latching claw, it can then, from the lower floor or location out, be hooked in the region of its free end on the hook of the assembly / disassembly auxiliary rod or added to this. Subsequently, this railing rod can be pivoted by means of the assembly / disassembly auxiliary rod upwards and fastened there via their provided at the still free end further latching claw on the uppermost rung of the second uppermost support frame. The disassembly of the railing rod is also done with the help of the assembly / disassembly auxiliary rod. For this purpose, first the latching claw attached to one end of the railing rod is released from the rung of the uppermost support frame by means of a nose attached to the operating end of the assembly / disassembly auxiliary rod, whereupon the railing rod can be lifted off the rung and pivoted downwards , In the same way, then the other latching claw of the railing rod can be released from the rung of the other support frame, after which the railing rod can also be removed from this rung and removed from the frame. Also in this solution, an additional component in the form of a long pole is mandatory for mounting / dismounting of the railing rods.

It is accordingly an object of the invention to provide a method for assembling and a method for disassembling a mobile scaffold or a mobile work platform, by the use of which the greatest possible safety in every situation, ie. H. Both during construction and during assembly of the mobile scaffolding and in the assembled state of the mobile scaffold, as well as during dismantling or during disassembly of the scaffold is achieved, without the need for an additional component would be mandatory.

This object is achieved by the features of claims 1 and 6 and by the methods described below.

In other words, the object can also be achieved by a method for assembling a mobile scaffold, which is constructed from vertical support frames, each having at least two stems and connecting them rungs for raising and / or dismounting people and / or for hanging scaffolding floors , Diagonal and / or horizontal fasteners, in particular struts or rods included, and which is composed of at least one lower scaffold floor and at least one upper scaffold floor, wherein the upper scaffold floor is constructed above the lower scaffold floor, and wherein said scaffolding floors Support frame of the support frame, preferably at the rungs thereof, supported and / or fixed, and wherein a support frame of the support frame is constructed, on which either a at least two railing elements comprehensive railing device is attached or are attached to the at least two railing elements, wherein the railing elements, in Direction d when viewed in a horizontal railing element spacing, laterally side by side, and wherein either the railing device is pivotally attached thereto relative to the support frame, or the railing elements are pivotable relative thereto to the support frame are attached, and wherein a support frame-suspension means for attaching a further support frame to be mounted, the support frame is or is attached to an already mounted support frame of the support frame, in particular at least one of its rungs, preferably at its uppermost rung , supported and / or which is supported by the support frame, and that the further support frame is releasably supported and / or suspended on the support frame suspension device and assumes a transient position in the supported there and / or hinged state and / or starting from the there abge supported and / or hinged state in a transition position arrives or is transferred, starting from which the further support frame is built into the scaffold or is installed, and that the railing device or the railing elements at the other Support frame is pivotally mounted relative to this or be, and that supported in the transition position on the support frame suspension device and / or hinged further support frame is detached or suspended from the support frame-suspension device and either together with the on the another support frame and also on the other support frame relative to this support frame pivotally mounted railing device or together with the other support frame and also on the other support frame pivotally mounted relative to these support frame railing elements, in particular of a person standing on the lower scaffold floor person in a position is raised, in which the further support frame is above the transition position or above the transition positions, or wherein the further support frame on or on the support frame and in, preferably viewed in the transverse direction or perpendicular to its rungs, a horizontal support frame distance, preferably parallel, is attached to the other support frame, and that the upper scaffold floor on the other support frame and also on the other support frame so, preferably at a distance below the railing device or the railing elements, arranged and fixed or is supported, that either the railing device, preferably as a back or hip protection element, to protect a person staying on the upper scaffold floor person from falling down or that the railing elements, preferably as back or hip protection elements, to protect yourself on the upper scaffolding floor rescuing person serve against falling off.

By the above measures, a mobile scaffold can be constructed on the principle of a "leading railing", at any time during assembly a great security against falling of people from the scaffold under construction and also of the built mobile scaffold is guaranteed.

In the Figures 14 . 37 and 51 are exemplary embodiments of three inventively constructed mobile scaffolds 1.1; 1.2 .; 1.3 shown. Each mobile scaffold 1.1; 1.2; 1.3 is made up of a plurality of vertical support frames 20; 120; 220 built. These each have two parallel stems 16.1, 16.2; 160.1, 160.2 and these connecting and perpendicular to these rungs 17; 217 for ascending and / or descending persons 52 and / or for suspending scaffolding floors 30; 130; 230, diagonal connection elements 50.1, 50.2; 51.1, 51.2 and / or horizontal connecting elements 18.1, 18.2; 18.3, 18.4. Each mobile scaffold 1.1; 1.2; 1.3 is here with or on two moving beams 2.1, 2.2 constructed. These are essentially formed of a horizontal beam, each of which has at each end in the assembled state vertically standing plug-in 3.1, 3.2. The insertion tubes 3.1, 3.2 each serve to receive a spindle 5 of a height adjustable by a nut 6 foot 4. Each foot 4 comprises a bottom plate 7, to which a conventional locking roller 8 is attached in a conventional manner. On the front spindles 5 here vertical tubes 10.1, 10.2 of a designated also as a base tube frame rod 9 are attached. This component provides a cohesion of the respective driving beams 2.1, 2.2 in the area each one of their ends. Under each horizontal beam of each trolley 2.1, 2.2 is attached to this in the case of the scaffolds 1.1 and 1.2, an auxiliary rung 11 and in the case of the scaffold 1.3 an auxiliary rung 111 by means of two vertical rung holders 12.1, 12.2. The auxiliary rungs 11, 111 are in such an altitude that when completely turned nuts 6 no ground contact occurs. So they are in the free space created by the feet 4 and the rollers 8 (see FIGS. 1 and 51 ). On the auxiliary rungs 11, 111 scaffold floors or planks can be placed and / or there, preferably by means of latching claws, releasably secured. In the case of the mobile scaffold 1.1 no scaffold floor is placed on the auxiliary rungs 11, while in the case of the scaffold 1.2 on the auxiliary rungs 11, a lowermost or first scaffold floor is placed 130.1. In the wider mobile scaffold 1.3, two lowermost or first scaffolding floors 230.1.1 and 230.1.2 are placed next to each other on the auxiliary rung 111.

Subsequently, the fitter with the frame bar 9 attached at one end to the first driving beam 2.1 goes to the second moving beam 2.2, whereby he slides the frame bar 9 by his hand and then also inserts the second vertical tube 10.2 of the frame bar 9 onto the free end of a spindle 5. which protrudes from the insertion tube 3.1 of the second driving beam 2.2 upwards. In this way, then the spindles 5 of the two moving beams 2.1 and 2.2 vertically or vertically aligned, so that the moving beams 2.1 and 2.2 are then prepared for further construction of the rolling stand 1.1. For this purpose, the fitter 52 arranges the two moving beams 2.1 and 2.2 approximately perpendicular to the frame rod 9. It is understood that at the other ends of the moving beam 2.1 and 2.2, in particular on or on the there vertically upwardly projecting spindles, a further horizontal connecting element, such as another frame bar, can be arranged or fixed.

Following the preparation of the approximately U-shaped or rectangular base unit consisting of the two moving beams 2.1 and 2.1 with their respective two locking rollers 8 and the frame bar 9 connecting the two moving beams 2.1 and 2.2, the installer 52 places or inserts one Support frame 20.2 vertically on the moving beam 2.2. Subsequently, the fitter fastened the two railing elements 18.1 and 18.2 with their provided at one end Einrastklauen 55 releasably and relative to the support frame 20.2 pivotally on or on the upper rung 17.1. Following this, the fitter 52 or another fitter, who is not shown in the figures, fetches a second support frame 20.1, wherein the fitter 52 holds the two railing elements 18.1 and 18.2 with their latching claws 55 at the other end Rung 17.1 of the second support frame 20.1, relative to this support frame 20.1 pivoted and also releasably attached. Following this, the fitter 52 can guide the supporting frame 20.1, which has hitherto still been supported on the ground, together with the two railing elements 18.1 and 18.2 fastened thereto and also to the other supporting frame 20.2 in a position upward, wherein he or she supports the second supporting frame 20.1 on the Position or attach the moving beam 2.1.

The construction situation in which the two support frames 20.1 and 20.2 are placed or plugged onto the respective moving beam 2.1 or 2.2 is in FIG. 2 shown. It also follows that, following the above-described assembly of the two support frames 20.1 and 20.2 and the two railing elements 18.1 and 18.2, the fitter installs the two diagonals 51.1 and 51.2 and a first scaffold floor 30.1. This is a so-called access ladder floor. It is understood, however, that instead of an access ladder floor and a scaffold floor can be used without access opening. The fitter then rises from the outside, especially from the ground, on this scaffold floor. Accordingly, this scaffold floor 30.1 has a passage opening 31, through which a person or a fitter 52 from a lower level, ie here from the ground, on the corresponding scaffold floor, that can rise to the scaffold floor 30.1. The access opening 31 can be closed by a cover not shown in the figures or with a flap, not shown, so that then the person or the fitter 52 can also stand on the lid or on the flap. How out FIG. 2 it can be seen, the diagonals 51.1 and 51.2 are parallel to each other between the two support frames 20.1 and 20.2 attached that their one-sided Einrastklauen 55 are respectively attached to the lowest rung 17.8 of the support frame 20.1 and that the other end provided Einrastklauen 55 of the diagonals 51.1 and 51.2 respectively on a rung 17.5 of the other support frame 20.2, also releasably secured. Subsequently or previously, the scaffolding floor 30.1 was fastened to the two support frames 20.1 and 20.2, which are constructed in a support frame spacing 21, such that this scaffold floor 30.1 is on or on the respective rung 17.5 of the respective support frame 20.1 and 20.2, preferably likewise with the aid of latching claws , detachable, fastened.

The further construction is in the FIG. 3 illustrated. This is initially compared to FIG. 2 shows that the fitter 52, after he has climbed from the ground through the access opening 31 of the scaffold floor 30.1 down to this here or a scaffold floor 30.1, below the serving as back and hip protection elements railing elements 18.1 and 18.2 other handrail elements in the form of knee rails 18.3 and 18.4 again detachably attached to the rungs 17.3 of the two support frames 20.1 and 20.2. Following this, the fitter 52 standing on the scaffold floor 30.1 picks up two elongated scaffolding components in the form of diagonals 50.1 and 50.2, which have been handed over to him by a second fitter not shown in the figures. These two diagonals 50.1 and 50.2 have latching claws 55 at their respective ends. The two diagonals 50.1 and 50.2 now mounted the fitter 52 in a horizontal distance 84 to each other such that they one end with one of their respective latching claw 55 on or on a rung 17.4 of the support frame 20.2 are fastened, so that these ends then form attachment ends 68. In the area of their other, free, ends, which are also provided with latching claws 55, the diagonals are 50.1 and 50.2 respectively on the top rung 17.1 of the support frame 20.1. The said free ends of the diagonals 50.1 and 50.2 protrude with the formation of Einhängeenden 67 over the spanned by the stems 16 and rungs 17 of the first support frame 20.1 vertical plane in the direction of the second support frame 20.2 away to the outside. These two diagonals 50.1 and 50.2 then, when mounted in the manner described above, together form a support frame suspension device 50 for suspending another support frame 20.4. How out FIG. 3 It can also be seen that a further support frame 20.4, which has been passed to the fitter 52 by the other fitter not shown in the figures, can thus be suspended in the support frame suspension device 50 formed from the two diagonals 50.1 and 50.2 in that a rung of the further support frame 20.4, here its rung 17.5, rests in the region of the free hook-in ends 67 of the respective diagonal 50.1 and 50.2 or is supported there. Due to the oblique installation position of the two diagonals 50.1 and 50.2, the fitter 52 can release the so hung on the support frame suspension device 50 further support frame 20.4, so that this then in the vertical position shown, ie perpendicular to the two diagonals 50.1 and 50.2 in a transition position 40 depends, and also secured against falling due to any occurring wind forces. Before or after suspending the additional support frame 20.4 on or on the support frame suspension device 50 forming diagonals 50.1 and 50.2, the fitter 52 can fix a third support frame 20.3 on the second support frame 20.2, preferably attach. Subsequently, the fitter 52 fastened to the uppermost rung 17.1 of the third support frame 20.3, another railing element 18.2 by releasably secured thereto by means of one end provided Einrastklaue 55 on the rung 17.1 of the third support frame 20.3 relative to this. Subsequently, the fitter 52 with the railing element 18.2 in the hand go to the other support frame 20.4. This is based on a support frame-suspension device 50 forming diagonals 50.1 and 50.2 on the top rung 17.1 of the first support frame 20.1 and protrudes me a substantial part 82 on the support frame 20.1 upwards. Subsequently, the fitter 52, who holds in one hand the railing element 18.2 in the region of its free end or the detent pawl 55 provided there, with his other hand, the further support frame 20.4, in particular at its upwards on the support points on the diagonals 50.1 and 50.2 or beyond the first support frame 20.1 also protruding part 82 and can then the other support frame 20.4 in a pivoting, the in FIG. 3 is marked with an arrow 86, pivot in the direction of the oppositely mounted third support frame 20.3 until he attaches the provided at the free end of the railing element 18.2 Einrastklaue 55 on or on the top rung 17.1 of the other or fourth support frame 20.4 can, whereupon he then makes the appropriate attachment. Subsequently, a construction position is reached as in FIG. 4 is shown. In this construction position, therefore, the further or fourth support frame 20.4 is still supported on the hooking ends 67 of the two diagonals 50.1 and 50.2 forming the support frame suspension device 50, but in an angular position relative to the perpendicular, namely in a further transitional position 40.1. Following the attachment of the railing element 18.2 to the respective uppermost rung 17.1 of the support frame 20.3 and 20.4, a same railing element 18.1 at one end with its Einrastklaue 55 on the uppermost rung 17.1 of the third support frame 20.3 and the other end of the upper rung 17.1 of the other or fourth Support frame 20.4 are releasably secured by means of the latching claw provided there, in a horizontal distance 19 of these railing elements 18.1 and 18.2 to each other. The assembly situation subsequently reached is in FIG. 4 illustrated. Starting from this further transition position 40.1, in which the further or fourth support frame 20.4 is still supported on the support frame suspension device or on the diagonals 50.1 and 50.2, it is now possible, as in FIG FIG. 5 illustrates the further or fourth support frame 20.4 together with the thereto and also on the third support frame 20.3 each releasably and respectively relative to these two support frames 20.3 and 20.4 pivotally mounted railing elements 18.1 and 18.2 are transferred upwards into a position in which the further or fourth support frame 20.4 attached to the first support frame 20.1, preferably attached, can be.

For this purpose, the fitter 52 starts from the in FIG. 4 shown transition position 40.1 the other or fourth support frame 20.4 as far as possible down, preferably on the stems 16.1 and 16.2, and then moves the other support frame 20.4 such a kind of curved track up that its lowest rung 17.8 at the free ends 67 of the diagonal 50.1 and 50.2 can pass upwards, as exemplified in the sub-phase according to FIG. 5 is illustrated.

Subsequently, the fitter 52, as already described above, the further or fourth support frame 20.4 put on the lower or first support frame 20.1 or attach, so that then the in FIG. 6 Example shown construction position is achieved. In this mounting position, therefore, are the first and the fourth support frame 20.1 and 20.4 and also the second and the third support frame 20.2 and 20.3 respectively in a vertical position, in which spanned by the respective support frame or its stems and rungs vertical planes of the mutually mounted support frame aligned with each other or coincide. Furthermore, in this, in FIG. 6 shown assembly position, then the attached to the upper ends or to the uppermost rungs 17.1 of the two support frames 20.3 and 20.4 railing elements 18.1 and 18.2 parallel to the at a distance from here eight consecutive rungs 17 further down the same railing elements 18.1 and 18.2 parallel to arranged this. This vertical distance between the railing elements 18.1, 18.1 and 18.2, 18.2 of the first and second floor or layer 15.1 and 15.2 is here 200 cm.

Following this, the fitter 52 releases the two diagonals 50.1 and 50.2 from the second support frame 20.2, respectively from its rung 17.5, and then installs these two diagonals 50.1 and 50.2 in the mobile scaffold 1.1 under construction, as exemplified in FIG FIG. 7 shown. In other words, the support frame suspension device 50, which is formed here by the two diagonals 50.1 and 50.2, are subsequently installed in the mobile scaffold 1.1 to be set up, or are subsequently installed in the mobile scaffold 1.1 to be built or constructed. For this purpose, the diagonal 50.1 can be fixed to the rung 17.4 of the first support frame 20.1 with the latching claw 55 provided at one end and can be fastened at the other end to the rung 17.5 of the third support frame 20.3 with the latching claw 55 provided there. In addition, the other diagonal 50.2 can be fixed at one end with its locking claw 55 on the rung 17.4 of the second support frame 20.2 and at the other end can be fastened with its latching claw 55 on the rung 17.5 of the further or fourth support frame 20.4. Subsequently, the two diagonals are 50.1 and 50.2 in the erected or constructed mobile scaffold 1.1 crosswise to each other or installed crosswise.

Following this, the fitter 52, still standing on the lower or first scaffolding floor 30.1, can install another or second or upper scaffold floor 30.2 in a position or position, as shown for example in FIG FIG. 8 is shown. Accordingly, the second or further or upper scaffold floor 30.2 can be releasably secured respectively to the rungs 17.5 of the third support frame 20.3 and the fourth support frame 20.4, so that subsequently the further or second upper scaffold floor 30.2 parallel to the lower or first scaffold floor 30.1 and can be arranged at a vertical distance, which is 200 cm here. In this case, the upper or further or second scaffold floor 30.2, which is likewise a scaffolding floor, is installed in such a way that its access opening 31 is arranged here perpendicular above the access opening 31 of the lower or first scaffold floor 30.1. It goes without saying, in that the access ramp floors on successive levels 15 can also be installed, each offset by 180 degrees relative to one another, so that their access openings 31 are arranged alternately with respect to the perpendiculars. This type of assembly has the advantage that a person can not fall completely down to the bottom, but only maximally to the down immediately following scaffold floor at any open access opening. The assembly of the further or second or upper scaffold floor 30.2 takes place at a distance 53 below the uppermost railing elements 18.1 and 18.2, such that or where these railing elements 18.1 and 18.2 then form a leading railing. Incidentally, these railing elements 18.1 and 18.2 then form back or hip protection elements for protecting a person staying on the second or further or upper scaffolding floor 30.2, here the fitter 52, against falling down.

Following installation of the further or second or upper scaffold floor 30. 2, the fitter 52, who has hitherto remained in the first floor 15. 1 or position on the first or lower scaffolding floor 30. 1, can pass through the access opening 31 of the second or upper scaffold floor 30 Climbing the upper or further scaffold floor 30.2 onto this further or second or upper scaffold floor 30.2, and when it stands on the second or further or upper scaffold floor 30.2, is already effectively prevented from falling through the leading railing, the is formed by the two railing elements 18.1 and 18.2, which form back and hip protection elements to protect against falling.

• Zunächst einmal baut der Monteur 52 die beiden Knieleisten 18.3 und 18.4 ein. Anschließend werden die beiden zukünftigen Diagonalen 50.1 und 50.2 als bzw. unter Ausbildung einer Stützrahmen-Einhänge-Einrichtung 50 eingebaut. Anschließend wird auf deren freie Einhängeenden 67 ein weiterer Stützrahmen 20 gehängt, der hier entsprechend der erfindungsgemäßen Aufbaufolge mit einer Aufbaueinheit aus vier einzelnen Stützrahmen, mit dem Bezugszeichen 20.4' gekennzeichnet ist. In der vertikalen bzw. lotrechten Einhängestellung befindet sich dann dieser weiteren Stützrahmen 20.4' in der Übergangsstellung 40', in welcher er an der von den Stielen 16.1 und 16.2 und Sprossen 17 des Stützrahmens 20.4 bzw. nunmehr 20.1' begrenzten Außenseite 81 des Fahrgerüsts 1.1 angeordnet ist und in welcher er, vorzugsweise wiederum mit etwa der Hälfte seiner Länge, den betreffenden Stützrahmen 20.4 bzw. 20.1' nach oben überragt. Vorher oder anschließend kann der weitere Stützrahmen 20.3' auf den Stützrahmen 20.3 bzw. nunmehr 20.2' aufgesetzt bzw. gesteckt werden und es kann daran, vorzugsweise wiederum an dessen oberster Sprosse 17.1, ein Geländerelement 18.2 mit einer einerends vorgesehenen Einrastklaue 55 lösbar befestigt werden. Daran anschließend kann der weitere Stützrahmen 20.4' bzw. dessen nach oben hinaus ragender Teil 82 in der Verschwenkrichtung 86 verschwenkt werden, worauf das andere Ende des Geländerelements 18.2 mit seiner Einrastklaue 55 an der obersten Sprosse 17.1 des weiteren Stützrahmens 20.4' lösbar befestigt werden kann. Daran anschließend kann dann auch ein weiteres Gerüstelement 18.1 mit Hilfe seiner Einrastklauen an bzw. auf der obersten Sprosse 17.1 des Stützrahmens 20.3' und an bzw. auf der obersten Sprosse 17.1 des weiteren Stützrahmens 20.4' lösbar befestigt werden. Anschließend befindet sich der weitere Stützrahmen 20.4' in einer gegenüber der Lotrechten geneigten weiteren Übergangsstellung, die in Figur 10 veranschaulicht ist. Daran anschließend kann, wie in Figur 11 veranschaulicht, der weitere Stützrahmen 20.4' zusammen mit den an diesem und an dem Stützrahmen 20.3' lösbar und relativ zu diesen Stützrahmen 20.4' und 20.3' verschwenkbar befestigten Geländerelementen 18.1 und 18.2 nach oben verschwenkt werden, und zwar bis in eine Stellung, von wo aus der weitere Stützrahmen 20.4' auf dem Stützrahmen 20.4 bzw. 20.1', vorzugsweise durch Aufstecken, befestigt werden kann und demgemäß auch befestigt bzw. aufgesteckt wird, so wie dies beispielhaft in Figur 12 gezeigt ist.

If a mobile scaffold even greater height to be built, then, as in the FIGS. 9 to 14 illustrates that the scaffold with at least one other floor, here the floor 15.3, continue to be built. The basic procedure in the further construction is the same, as already described above in connection with the structure of the components for the second equipment days 15.2. Accordingly, the other structure starting from FIG. 9 , which of the construction sequence from FIG. 4 corresponds as follows:

• First of all, the fitter 52 builds the two knee rails 18.3 and 18.4. Subsequently, the two future diagonal 50.1 and 50.2 are installed as or to form a support frame suspension device 50. Subsequently, a further support frame 20 is hung on the free Aufhängeenden 67, which is here according to the construction sequence according to the invention with a structural unit of four individual support frame, designated by the reference numeral 20.4 '. In the vertical or vertical Einhängestellung is then this further support frame 20.4 'in the transition position 40', in which he arranged on the of the stems 16.1 and 16.2 and rungs 17 of the support frame 20.4 and now 20.1 'limited outside 81 of the mobile scaffold 1.1 is and in which he, preferably in turn with about half its length, the respective support frame 20.4 and 20.1 'surmounted above. Before or subsequently, the further support frame 20.3 'on the support frame 20.3 or now 20.2' put on or stuck and it can, preferably in turn on the top rung 17.1, a railing element 18.2 are releasably secured with a one-end latching claw 55. Subsequently, the further supporting frame 20.4 'or its upwardly projecting part 82 can be pivoted in the pivoting direction 86, whereupon the other end of the railing element 18.2 can be releasably secured with its latching claw 55 on the uppermost rung 17.1 of the further supporting frame 20.4'. Subsequently, a further scaffold element 18.1 can then be detachably fastened by means of its latching claws on or on the uppermost rung 17.1 of the supporting frame 20.3 'and on or on the uppermost rung 17.1 of the further supporting frame 20.4'. Subsequently, the further support frame is 20.4 'in a relation to the perpendicular inclined further transition position, the FIG. 10 is illustrated. Then, as in FIG. 11 illustrates the further support frame 20.4 'together with the on this and on the support frame 20.3' detachable and relative to these support frame 20.4 ' and 20.3 'pivotally mounted railing elements 18.1 and 18.2 be pivoted upwards, to a position from where the further support frame 20.4' on the support frame 20.4 or 20.1 ', preferably by plugging, can be attached and accordingly also fixed or . is plugged, as exemplified in FIG. 12 is shown.

Subsequently, the elongated scaffolding components 50.1 and 50.2, which previously functioned as support frame suspension elements, can be removed and installed in their function as diagonals 50.1 and 50.2 in the mobile scaffold 1.1 to be set up, as described, for example, in US Pat FIG. 13 is illustrated.

Subsequently, the fitter 52 'standing on the scaffold floor 30.2 or now 30.1' mounts the third scaffolding floor 30.3 (FIG. Fig. 14 ). This scaffold floor is in the current construction sequence with four support frames to the upper and then second scaffold floor 30.2 '. This is mounted in a vertical distance 53 below the two now uppermost, a leading railing forming railing elements 18.1 and 18.2, again at a vertical distance to an underlying scaffold floor 30.2 and 30.1 ', the distance of this scaffolding floor from the first scaffold floor Corresponds to 30.1 and therefore in the exemplary embodiment is about 200 cm.

Following this, the fitter, who has previously been on the second scaffolding floor 30.2 or 30.1 ', climb through the access opening 31 of the third scaffold floor 30.3 or 30.2' through this top scaffolding floor 30.3 or 30.2 'and then it is from the beginning at by the respective a back or hip protection element forming railing elements 18.1 and 18.2 secured against falling. Subsequently, the fitter 52 can also mount the two knee strips 18.3, 18.4 and the toe boards 85.1 and 85.2, so that 15.3 or position, which is formed with the uppermost scaffold floor 30.3 or 30.2 ', then in the top floor 15.3, an optimally secure Working is possible. Accordingly, the shows FIG. 14 a with three floors 15.1 to 15.3 inventively constructed mobile scaffold 1.1.

The disassembly of this mobile scaffold 1.1 according to the invention is based on the FIGS. 14 to 24 and the resulting sequence and is described in more detail below:

Starting from the fully assembled mobile scaffold 1.1 according to FIG. 14 dismantled the fitter 52 first, the two knee bars 18.3 and 18.4 in the top floor 15.3 and gives them down. Subsequently, the fitter 52 climbs through the access opening 31 of the uppermost scaffolding floor 30.2 'or 30.3 through to the scaffold floor 30.2 or 30.1' located underneath. From there, the fitter 52 then dismantles the uppermost scaffold floor 30.2 'or 30.3 and also gives it down. Subsequently, the fitter dismantles the two diagonals 50.1 and 50.2 and then builds them as a support frame suspension device 50, for example in the in FIG. 15 shown position again. For this purpose, ie the diagonals 50.1 and 50.2 are provided with their one-stop Einrastklauen 55 on a rung 17.4 of under the uppermost support frame 20.3 "or 20.4 'mounted support frame 20.2", 20.4, 20.3 "', in a horizontal distance 84th In the region of their other free ends, the diagonals 50.1 and 50.2 rest on the uppermost rung 17.1 of the support frame 20.3, 20.1 ", 20.4"'mounted opposite, as likewise in FIG FIG. 15 illustrated. The then with their attachment ends 68 on the rung 17.4 of the support frame 20.2 ", 20.4, 20.3"'attach diagonal 50.1 and 50.2 then protrude with their free ends in the direction of their attachment ends 68 away over the support frame 20.3, 20.1 ", 20.4"' to the outside, so that the free ends of the diagonal 50.1 and 50.2 can then serve as a free hooking 67 for hanging a support frame to be demounted, here the support frame 20.3 ', 20.4 ", in an intermediate position.

After installation of the diagonals 50.1 and 50.2 to form a support frame suspension device 50 of standing on the scaffold floor 30.2, 30.1 'fitter 52 lifts the support frame 20.3', 20.4 "together with the attached thereto and on the support frame 20.3", 20.4 ' Railing elements 18.1 and 18.2 of the support frame 20.3, 20.1 ", 20.4"'and then moved the support frame 20.3', 20.4 "down so that its lowest rung 17.8 passes the free hooking 67 of the diagonal 50.1 and 50.2 over, whereupon the support frame 20.4 ", as in FIG. 16 illustrated, preferably supported by the rung 17.5 on the free hooking ends 67 of the diagonal 50.1 and 50.2. Then the support frame is 20.4 "in the in FIG. 16 shown skew, which is a transition position. Starting from this oblique or transitional position of the support frame 20.4 "the fitter 52 then solves the two railing elements 18.1 and 18.2 of the support frame 20.4", whereupon he fixes these two railing elements 18.1 and 18.2, preferably by depositing them on his shoulders or by he fixed it on a shoulder and holding in one hand, whereupon he can let go of the demounting support frame 20.4 ".This then causes the support frame 20.4" in a pivoting direction according to the arrow 87 in FIG. 16 shown, pivoted alone by the force acting on it gravity in a vertical or vertical transition position 40 ", as in FIG. 17 is shown, wherein the support frame 20.4 "to the in the Figures 16 and 17 illustrated horizontal pivot axis 57 pivoted. Subsequently, the fitter 52 can raise the two guardrails 18.1 and 18.2 in the direction of the arrows 58 or to the support frame 20.3 "or fold by gravity, so that then the two still on their Einrastklauen 55 at the top rung 17.1 of the support frame 20.3 "fixed and there hanging railing elements 18.1 and 18.2 are in a position as in FIG. 18 is illustrated.

The release of the railing elements 18.1 and 18.2 of the support frame 20.3 "respectively of the top rung 17.1 may conveniently with Help an elongated scaffolding component done, which was previously installed in the scaffold 1.1. Particularly suitable for this is a knee bar 18.3 or 18.4, wherein in FIG. 18 the knee bar 18.3 is used. For the purpose of solving the respective railing element 18.1 and 18.2 of the support frame 20.3 "is the knee bar 18.3 on the immediately below that rung 17.1, to which the respective railing element 18.1 and 18.2 is attached, then serving as an operating end end 62 on the rung 17.2 of the support frame 20.3 "and simultaneously applied to a locking finger, not shown in the figures, of the respective latching claw 55 with which the respective railing element 18.1 and 18.2 is fastened to the support frame 20.3" the rung 17.2 extending pivot axis 63 so far pushed back in a vertical pivot plane in the direction of arrow 88 of the locking fingers against the spring forces acting on him until the affected railing element 18.2 and 18.1 can be solved by the rung 17.1, after which the respective railing element 18.2 bzw. 18.1 from this rung 1 7.1 is solved. This method is used for releasing or disassembling both upper railing elements 18.1 and 18.2 from the support frame 20.3 ", whereupon these two railing elements 18.1 and 18.2 can be given downwards, then the support frame 20.3" is removed and also the support frame suspensions previously Device 50 acting diagonals 50.1 and 50.2 be expanded as well as the previously mounted knee bar 18.4, whereupon these scaffolding components can be down against. The then remaining components of the rolling stand 1.1 are in FIG. 19 shown.

To remove the now uppermost scaffolding floor 30.2 of the hitherto residing installer 52 climbs down through the access opening 31 of this scaffold floor 30.2 down to the lowest or first scaffold floor 30.1, from where the installer 52 remove the top or second scaffold floor 30.2 and down can give. Following this, the remaining diagonals 50.1 and 50.2 are removed and again under Forming a support frame suspension device 50, as previously described, reinstalled. The diagonals 50.1 and 50.2 are thus fastened with the provided at one of its ends Einrastklaue 55 on the rung 17.4, ie here at the lowest rung of the support frame 20.3 "', wherein they mounted in the region of their other ends on the top rung 17.1 of the opposite Support frame 20.1 '"are placed so that then their free ends can act as Einhängeenden 67 for suspending the demounting further support frame 20.4"' Next, the support frame 20.4 "'from the support frame 20.1"' lifted and preferably with his rung 17.5 the Aufhängeenden 67 of the diagonals 50.1 and 50.2 supported or hooked there, again in an oblique or transitional position, as in FIG. 20 is illustrated.

Starting from this oblique or transition position of the support frame 20.4 '', the fitter 52 can then solve the two upper railing elements 18.1 and 18.2 of the support frame 20.4 "'and then the support frame 20.4"' in the in FIG. 21 shown vertical or vertical transition position 40 '"can pivot, in which the support frame 20.4"' then alone by the diagonal 50.1 and 50.2 depends on these. Then the fitter 52 can pivot the two uppermost railing elements 18.1 and 18.2, which are still attached to the uppermost rung 17.1 of the support frame 20.3 "'in the direction of the arrows 58 on or on the support frame 20.3"' or pivot there, so they finally get out in the FIG. 22 emerging vertical position on the top rung 17.1 of the support frame 20.3 "hang '.

Subsequently, the fitter 52 again builds one of the knee rails 18.3 and 18.4, here the knee bar 18.3 from the remaining part of the frame 1.1 and then uses this knee bar 18.3 as disassembly aid for releasing the railing elements 18.2 and 18.1 of the top rung 17.1 of the support frame 20.3 "'For this purpose, the corresponding knee strip 18.3 is again supported on the second highest rung 17.2 and at the same time on the Not shown locking finger of the latching claw of a disassembled railing element 18.2 and 18.1 applied and then so far pivoted in the direction of arrow 88 until the respective railing element 18.2 or 18.1 of the top rung 17.1 of the support frame 20.3 "'is solvable 52 the corresponding railing elements 18.1 and 18.2 and then can give them down.

As a result, the fitter 52 removes the second knee bar 18.4 and the two remaining diagonals 50.1 and 50.2, which have hitherto served as the support frame suspension device 50 or support frame suspension elements, as well as the support frame 20.3 "' from the still remaining scaffold floor 30.1 through its access opening 31 to the floor, from where it can dismantle the last remaining scaffold floor 30.1 The remaining components of the scaffold 1.1 are in FIG. 23 shown. Now, the fitter 52 standing on the ground can see one of the remaining supporting frames, for example as in FIG FIG. 24 shown, the support frame 20.2 "', lift off the moving beam 2.1 and put on the ground.After this, the fitter of this support frame 20.2"' can solve the two remaining railing elements 18.1 and 18.2. Subsequently, the support frame 20.2 "'away be cleared and the two railing elements 18.1 and 18.2, which are still attached by means of their Einrastklauen 55 on the top rung 17.1 of the remaining support frame 20.1"', can be pivoted on or on these in a vertical position Whereupon these two handrail elements 18.1 and 18.2 can also be released manually from the support frame 20.1 "." Finally, the support frame 20.1 "'is also removed from the moving beam 2.2. Thereafter, the frame rod 9 is removed and also the remaining parts can be dismantled or put away.

The assembly and disassembly of the scaffold 1.2 is based on FIGS. 25 to 46 illustrated. The structure of a leading railing, here also in each floor 15.1 to 15.3 each with two back respectively Hüftschutzelemente forming railing elements 18.1 and 18.2 is constructed, and also the dismantling, takes place in principle the same, as based on the embodiment of the mobile scaffold 1.1 according to the FIGS. 1 to 24 shown and described. A principal difference in the construction or dismantling of the rolling stand 1.2 is that this is built from the lowest support frame 120.1 and 120.2, the body length here is only half as large as the body length of the lowest support frame 20.1 and 20.2 of the mobile 1.1. The preparation for setting up said two support frames 120.1 and 120.2 of the rolling stand 1.2 on the moving beam 2.1 and 2.2 takes place in the same manner as described above in connection with the structure of the rolling tower 1.1, so that it can be referred to for simplicity. It is therefore in turn a unit consisting at least of the two moving beams 2.1 and 2.2, attached thereto a total of four locking rollers 8 and at least one frame bar 9 is formed, which connects the two running frame 2.1 and 2.2. In contrast to the mobile scaffold 1.1 is to build the scaffold 1.2 on or on the respective auxiliary rungs 11, which are below the respective horizontal beam of the respective moving beams 2.1 and 2.2 attached to this, a first or bottom or bottom scaffolding floor 130.1 supported or attached, which may be, for example, a scaffold board. On the moving beams 2.1 and 2.2, one of the short supporting frames 120.1 and 120.2 is set up or attached respectively. In this way you get the in FIG. 25 shown construction situation. On the basis of this, two diagonals 50.1 and 50.2 are fastened to one another at the lowest rung 17.4 of the second support frame 120.2 at a horizontal distance 84 by means of their latching claws 55 provided at one end, so that these ends then function as attachment ends 68. In the region of their other ends, the diagonals 50.1 and 50.2 rest on the uppermost rung 17.1 of the opposite first support frame 120.1, their free ends extending away from the support frame 120.2 extending beyond the support frame 120.1 and extending outwardly in this way Hanger 67 to hang for mounting another support frame 20.4 to be mounted in a transition position 40.

After mounting the diagonals 50.1 and 50.2 for the purpose of forming a support frame suspension device 50 is on or on the free ends 67 of the diagonal 50.1 and 50.2 another supporting frame 20.4 supported or suspended such that this with its rung 17.5 there rests. In this transitional position 40, therefore, the further support frame 20.4 hangs in a vertical or vertical position on the free hooking ends 67 of the diagonals 50.1 and 50.2 and is supported only by these diagonals 50.1 and 50.2.

On the support frame 120.2, a support frame 20.3 is fastened or attached to it, in such a way that the vertical planes formed by the support frame 120.2 and by the support frame 20.3 coincide. At the uppermost rung 17.1 of the support frame 20.3, a railing element 18.2 is releasably secured by means of a one-end latching claw 55 and pivotable relative to the support frame 20.3. Subsequently, the fitter holds this railing element 18.2 in the region of the other, still free end and pivots the other support frame 20.4 about the horizontal pivot axis 57 in the direction of arrow 86 as long or so far until he the railing element 18.2, respectively at the free end provided latching claw 55 can attach to the uppermost rung 17.1 of the support frame 20.4, whereupon he attached the railing element 18.2 according to the rung 17.1 of the support frame 20.4 again releasably and relative to the support frame 20.4 pivotally attached.

Then the fitter attaches another equal railing element 18.1 with a one-piece provided latching claw turn on the top rung 17.1 of the support frame 20.3 and the other with a further latching claw 55 on the top rung 17.1 of the located in a sloping and transition position 40.1 support frame 20.4. The assembly position then reached is in FIG. 27 shown. Thereupon, the fitter 52 moves the support frame 20.4, together with the support frame 20.3 pivotally attached thereto and also to the support frame 20.3 already mounted at a distance to these two support frames 20.4 and 20.3, thus upwards into a position above the transition position 40 and also above Transitional position 40.1, that the support frame 20.4 can be performed with its lowest rung 17.8 at the free ends of the diagonals 50.1 and 50.2 over up to a position from which then the support frame 20.4 attached to the bottom support frame 120.1 or put can FIG. 29 ). Subsequently, the upper or further support frame 20.4 is mounted on the lower support frame 120.1, or put on this, then according to the Aufbaufolge invention of a construction unit of four support frame then the first four support frames 120.1, 120.2, 20.3 and 20.4 are constructed, as in FIG. 30 illustrated.

Then the fitter builds the two diagonals 50.1 and 50.2, which previously served as a support frame suspension device 50 for the other support frame 20.4, from where he now these two elongated scaffolding elements in their function as diagonals 50.1 and 50.2 back into the mobile scaffolding to be built 1.2 installed or installed there, as for example in FIG. 30 is illustrated. In this case, the diagonal 50.1 is fastened with its latching claw 55 provided at one end to the lowermost rung 17.4 of the first support frame 120.1 and is fastened with its latching claw 55 provided at its other end to the rung 17.5 of the third support frame 20.3. The other diagonal 50.2 is fastened with one of its latching claws 55 to the lowest rung 17.4 of the second support frame 120.2 and is fastened with its other latching claw 55 to the rung 17.5 of the fourth or further support frame 20.4. Accordingly, the two lowermost diagonals 50.1 and 50.2 are also installed over the cross or intersecting to build the scaffold 1.2.

Subsequently, the fitter 52 standing on the lowest scaffold floor 130.1 installs a further or upper or second scaffold floor 30.2, which is an access scaffold floor with an access opening 31. The installation of this upper or second scaffold floor 30.2 is carried out in such a manner at a distance 53 below the upper railing elements 18.1 and 18.2 that they form a leading railing, such that they as back or hip protection elements to protect themselves on the upper or serve the second scaffolding floor 30.2 restraining person against falling.

The further construction of the mobile scaffold 1.2 is the same as the structure of the mobile scaffold 1.1 according to the FIGS. 9 to 14 , wherein this further construction of the rolling stand 1.2 in the FIGS. 32 to 37 also according to the resulting construction sequence can take place.

An inventive disassembly of in FIG. 37 shown, completed with three floors 15.1 to 15.3 or layers finished scaffold 1.2 is carried out in the same manner as the dismantling of the rolling tower 1.1, namely as there on the basis of FIGS. 15 to 19 illustrated and described above. The corresponding disassembly or disassembly sequence during disassembly of the rolling stand 1.2 is in the Figures 37 to 42 illustrated.

The subsequent disassembly of the mobile scaffold 1.2 is similar to the further disassembly of the mobile scaffold 1.1, starting from the FIG. 20 , If you go for the further disassembly of the scaffold 1.2 of the in Figure 42 dismantling situation shown, the next dismantling of the now top, second scaffolding floor 30.2, of a fitter standing on the lowest scaffold floor 130.1, in particular of the fitter who was previously on the top scaffold floor 30.2 and from there through the Durchgangssfifnung 31 has passed through the bottom of the scaffold floor 130.1.

After the scaffolding floor 30.2 has been removed, the fitter 52 removes the two remaining diagonals 50.1 and 50.2 and subsequently constructs them, as in FIG FIG. 43 shown again as a support frame suspension device 50 for a support frame still to be demounted, here for the support frame 20.4 "', for this purpose the two diagonals 50.1 and 50.2 are each provided with a latching claw 55 provided at one end thereof. on the lowest rung 17.4 of the support frame 120.2 "', so that these ends then act as attachment ends 68. The thus secured diagonal 50.1 and 50.2 are installed so that they rest in the region of their other ends on the top rung 17.1 of the spaced opposite support frame 120.1 "', with their free ends outwardly beyond this support frame 120.1"' out of this way and after installation of the diagonals 50.1 and 50.2 as a support frame suspension device 50, the installer 52 releases and moves the support frame 20.4 "'from the underlying support frame 120.1 with the railing elements 18.1 and 18.2 fastened to its uppermost rung 17.1 so downwards into an oblique and transitional position 40.1 that the rung 17.5 of the supporting frame 20.4 "'rests on the hooking ends 67 of the diagonals 50.1 and 50.2 FIG. 43 illustrated.

Based on this, the fitter 52 releases the two upper railing elements 18.1 and 18.2 from the support frame 20.4 "'and then releases them, so that the support frame 20.4''then moves into the in FIG. 44 shown vertical or vertical transition position 40 '"can pivot, in which the support frame 20.4"' depends on the formed with the two diagonals 50.1 and 50.2 support frame-suspension device 50 only supported by this.

Subsequently, the fitter 52 pivots the two railing elements 18.1 and 18.2 in the direction of the arrows 58 on or on the support frame 20.3 '' in one vertical position in FIG. 45 The two railing elements 18.1 and 18.2 are thus suspended vertically at the uppermost rung 17.1 of the support frame 20.3 "'by means of their latching claws 55. To release the two railing elements 18.1 and 18.2, an elongate scaffolding element is again used, preferably one previously described in US Pat the mobile scaffold 1.2 built knee bar 18, here the knee bar 18.3, the disassembly or release process is the same, as already described above in connection with the disassembly of the rolling tower 1.1.

After the two railing elements 18.1 and 18.2 have been detached from the support frame 20.3 "', this support frame 20.3"' is also dismantled, ie detached and detached from the support frame 120.2 "The remaining components of the rolling stand 1.2 are in FIG. 46 shown. Then only the two short support frames 120.1 "'and 120.2"' have to be released from their respective moving beam 2.2 or 2.1 and the lowest framework floor 130.1 has to be lifted or released from the two auxiliary rungs 11. Then also the remaining unit of the two moving beams 2.1 and 2.2 and attached thereto four locking rollers and the frame bar or base pipe 9 can be dismantled.

The assembly and disassembly of the in FIG. 51 shown further embodiment of a scaffold 1.3 is carried out substantially the same as the assembly and disassembly of the scaffold 1.2, with the difference that are mounted on the correspondingly wider support frame 220 per layer or floor 15.1 to 15.4 two scaffolding floors side by side, which accordingly during disassembly be dismantled again. It is sufficient if from the second floor 15.2 to the highest floor 15.4 only one of the two scaffolding floors 30.2, 30.3, 30.4 designed as a scaffold floor with a access opening 31, while all other scaffold floors 230.1.1, 230.1.2; 230.2, 230.3, 230.4 can be designed as full-scaffold floors, ie without access opening, as exemplified in FIG. 51 is shown.

An alternative embodiment of a support frame suspension device 150 is shown in FIGS FIGS. 47 to 50 shown in connection with some relevant mounting positions during the assembly of a mobile scaffold. This support frame suspension device 150 is a separate additional component 70 which is not installed or installed in the mobile scaffold that is to be built or finished with other, in particular load-bearing, scaffolding components. This additional component 70 can be designed as a U-profile 72, which can be formed or produced with a plate-shaped base body 73 and two support legs 74.1 and 74.2 extending away from it in the same directions. Preferably, the support legs 74.1 and 74.2 are bent or bent from the base body 73. Regardless, the support legs 74.1 and 74.2 may be made in one piece with the base body 73.

The support legs 74.1 and 74.2 are approximately perpendicular to the base body 73 and each have a support frame hook-in hooks 71.1, 71.2 at their upper ends in the mounting position. The support frame suspension hooks 71.1 and 71.2 are arranged at a horizontal distance 75 from each other. The suspension hooks 71.2 and 71.1 define recesses 89.2 and 89.1, which are each intended to receive a rung 17.1, 17.2 of a support frame 20.4 to be suspended, mounted or demounted there in a transitional position 40, 40.1. At the back of the additional component 70 is a, preferably integrally formed with the base body 73, hooking device 76 is formed, which is designed here with four hooks 76.1 to 76.4. In this case, two upper hooks 76.1 and 76.2 are provided for suspending the additional component 70 and the support frame-Einhänge-device 150 at an upper rung 17.1, and spaced therefrom two lower hooks 76.3 and 76.4 are provided which an additional hooking or support of the Additional component 70 or the support frame-Einhänge-device 150 at a lower rung 17.2 of the same support frame 20 allows. The Suspension hooks 76.1 to 76.4 are formed out of the base body 73 in the embodiment shown and manufactured by bending or folding relative to the base body 73 in a position perpendicular thereto.

The distances of the hooks 76.1 and 76.2 and their rung support surfaces of the lower hooks 76.3 and 76.4 or of their rung support surfaces are chosen so large that they correspond to the distance between two rungs 17, preferably two immediately adjacent rungs 17.1 and 17.2. It is understood, however, that a support frame suspension element designed as an additional component can also have only one or only two suspension hooks for hanging on a support frame, preferably on a rung 17 of a support frame 20, 120, 220.

For a mounting of a mobile scaffold according to the invention, the support frame suspension device 150 or the additional component 70 can be hung on the rungs 17.1 and 17.2 of a mounted support frame 20, 20.1, whereupon in the limited by the support frame hooks-71.1 and 71.2 recesses 89.1 and 89.2 a rung 17, for example, the rung 17.4 of a, for example, eight rungs comprehensive support frame 20, 20.4 can be hung, as for example in FIG. 48 is shown.

In order to allow a vertical or vertical Nachuntenhängen there suspended support frame 20, 20.4 in a corresponding transitional position, the support legs 74.1 and 74.2 taper in the direction of their Einhängehaken 71.1 and 71.2 away, so in the assembled state down. As a result, a support frame 20, 20.4 suspended there in its transition position 40 can be suspended vertically or vertically and securely, preferably only from the support frame suspension device 150 or from the additional component 70.

Starting from the in FIG. 48 shown transition position 40, the suspended there support frame 20, 20.4 relative to the support frame-suspension device 150 and also relative to the supporting these lower support frame 20, 20.1 are pivoted about a coincident with the longitudinal axis of the rung 17.4 of the support frame 20.4 pivot axis 57 in an inclined and transitional position 40.1, as exemplified in FIG. 49 is shown. In this position, the two railing elements 18.1 and 18.2 can be connected to the uppermost rung 17.1 of the further support frame 20.4. After removing the support frame 20.4 from the support frame-Einhänge-device 150 and lifting the support frame 20.4 together with the attached railing elements 18.1 and 18.2 up to a position from where the support frame 20.4 attached to the support frame 20.1, preferably plugged can, the support frame 20.4, as in FIG. 48 shown mounted on the support frame 20.1 or placed on this. Then the results in the partial view according to FIG. 50 illustrated assembly position.

The additional component 70 functioning as a support frame suspension device 150 can then be unhooked and hung again at another location for assembly or disassembly of a or the mobile scaffolding, in order also to build up a leading railing or an assembly according to the invention at this further position to allow a scaffold or a disassembly of a mobile scaffold according to the invention.
