Description

Assembly basket and method for safe erection

a scaffold or a scaffolding tower

The present invention relates to a mounting basket for use in erecting a scaffold or a shoring tower, and a mounting method for safely erecting a scaffolding tower.

Shoring towers of the type in question are commonly used in construction as a support structure and are able to safely remove relatively large loads. As in the case of scaffolds, such scaffold towers generally generally consist of a large number of individual components such as, for example, supports, bars, diagonals and frames

FR 2 939 464 AI described shoring tower is the case. The individual components are assembled by a fitter, whereby the shoring tower successively grows in height. However, as the altitude increases, the danger of falling for a fitter on the shoring tower increases. Although in every second frame level of the support tower described in FR 2 939 464 AI support grids are installed, which are mounted in opposite bars; However, these support grids must be mounted from below in overhead mounting, which proves to be problematic from a working ergonomic point of view. In addition, after installation of these grids, the installer has the opportunity to enter the assembly level so created before the bars of the next higher scaffold level are mounted, which could secure him from any crash. Since occupational safety and ergonomics not only in Germany and France, but also in other European and non-European states increasingly important, the invention has for its object to provide at least one implementation, with the occupational safety and ergonomics in the establishment of a Basement tower or scaffolding in general.

According to a first aspect of the present invention, a solution according to claim 1 for use in the construction of a scaffold or a supporting tower is proposed to solve this problem, which has a walk-on flooring and a railing arrangement extending above the flooring. The floor covering is at least partially surrounded by the railing arrangement. In addition, the assembly basket has two perpendicular to the plane of the flooring offset from each other coupling devices, via which the mounting basket can be coupled to a support of a scaffold or shoring tower to be built. The construction of, for example, a shoring tower using at least one assembly basket according to the invention proceeds in such a way that a mounting basket is coupled via its coupling devices with an already installed support of the shoring tower, in particular with the rosettes of the support, so that a fitter located on the floor covering of the assembly basket in the protection of the floor covering at least partially surrounding railing assembly can install other scaffolding components such as bars, columns or diagonals. Preferably, in this case, the assembly basket can be coupled with the already installed support of the support tower so that the floor covering of the assembly basket is approximately level with the bar of the support frame. ten platform level, which requires that at least one of the coupling devices is located below the floor covering. The railing arrangement of the assembly basket thus extends above the bolt of the uppermost scaffold level, so that an installer located in the assembly basket does not have to act overhead when installing further scaffold components. By using the assembly basket according to the invention thus not only the work safety, but also the working ergonomics is improved in the construction of a shoring tower.

For the construction of shoring towers with a maximum bolt or side length of about 1, 5 m while only two mounting baskets according to the invention are required because a fitter who is in a coupled with a support of the shoring tower assembly basket, from this basket from a second mounting basket over the distance of 1, 5 m away easily seize and implement. However, a second mounting basket is required to build a shoring tower in any case, otherwise an installer who is in a coupled with a support mounting basket would have to leave the same to lift this mounting basket and to connect with another support can. Since the fitter would not be protected against falling, therefore, two mounting baskets according to the invention are used, so that the fitter starting from one of the mounting baskets each other raise, implement, pair with another support and finally can enter to from this other mounting basket then to install additional scaffolding components.

The fitter is thus in the construction of a shoring tower alternately in one of the two mounting baskets and is thus always secured by the respective railing arrangement against falling. The change between the two mounting baskets is not critical, since at a maximum bolt length of about 1, 5 m only a small distance or gap between the two mounting baskets exists, the fitter must overcome when changing between the two mounting baskets. With a maximum bar length of about 1.5 m, this distance is even so small that the installer can not crash through it.

Accordingly, in the construction of shoring towers with a maximum bar or side length of about 2 to 3 m four assembly baskets are used, each of which is coupled to one of the four supports of the shoring tower. With a bar or side length of about 2 m and more, namely, the distance between two mounting baskets would be too large, that an umdendeter change between the mounting baskets would be possible. In addition, an installer can take over this large bolt length away a mounting basket and implement poorly, which is why for reasons of ergonomics from a bolt length of about 2 m four mounting baskets in the construction of a shoring tower are used, in which case the shorter bolt length also should not be larger than about 1, 5 m. The assembly is carried out by two fitters who are alternately in those mounting baskets, which are spaced from each other by the respective shorter latch.

The assembly basket according to the invention thus provides the fitter during the construction of a scaffold or shoring tower at any time during installation optimal protection, since it is reliably secured by the railing assembly of the assembly basket against falling. In addition, the use of the assembly basket according to the invention proves to be advantageous in that, in addition to the framework components which are required for static reasons, no further scaffolding components are required. necessary. Thus, only the structural material required for static reasons must be moved, whereby weight, working time and thus costs can be saved. According to a further aspect of the present invention, the object underlying the same is also achieved by a mounting method for safely erecting a scaffold or a supporting tower, in which first a scaffolding plane with circumferential bars, which are supported by first supports located in the corners of the first scaffolding plane, is produced is before then a first inventive mounting basket is coupled to one of the first supports such that its railing assembly extends beyond the first frame level also upwards. In a corresponding manner, a second mounting basket according to the invention is then coupled to another of the first supports in such a way that its railing arrangement extends upwards beyond the first frame plane. A fitter can then mount further scaffolding components and, in particular on the first struts, at least indirectly standing second struts, under the protection of the railing arrangements of the two assembly baskets, with which the two assembly baskets can then be coupled in subsequent assembly steps. In the

Assembly of the second supports and other scaffolding components, which are coupled with these second supports, the alternately located in the two mounting baskets fitter is thus always secured against falling.

In the following, reference will now be made to advantageous embodiments of the invention; Further advantageous embodiments may also be apparent from the dependent claims, the description of the figures and the drawings. The following, explained with reference to the assembly basket according to the invention and the assembly method according to the invention features apply in a corresponding manner for the not explicitly taken into account each item.

Thus, it is provided according to a first embodiment of the assembly basket according to the invention that the railing arrangement comprises a first and a second railing element, which are provided to form two access areas at the periphery of the flooring spaced from each other. The access areas are preferably aligned at right angles to each other and can taper downwards in the vertical direction. The tapering of the access areas can thereby be realized in that extend the first and / or the second railing element obliquely outwards from the floor covering, whereby at the same time the work area available to the installer is increased inside the mounting basket.

The passage areas between the two guardrails ensure that an installer can easily access and leave the assembly basket. Thus, in order to get into the assembly basket, the installer does not have to climb over the railing arrangement; Rather, the installer can easily get from a mounting basket in an adjacent mounting basket through the respective access area, which not only the work safety, but also the work ergonomics is promoted.

The fact that the two access areas of the assembly basket according to the invention preferably extend at right angles to each other has the further advantage that thereby the assembly basket in accordance with the geometrical conditions of a supporting tower to be built in two can be entered and left at right angles to each other aligned directions. An installer who is in a coupled with a support mounting basket, so can easily get into another mounting basket, regardless of which adjacent support this other mounting basket is coupled.

In order that an installer located in a mounting basket can not inadvertently pass through one of the access areas, it is provided according to a further embodiment that a shut-off means such as a chain, a bolt or the like is provided for each of the passage areas with which the respective access area can be shut off when needed. To enter the assembly basket, the respective blocking means can be brought into a position in which the associated access area can be passed unhindered. After the fitter has entered in this way through one of the access areas into the interior of the mounting basket, he can then bring the shut-off again in its locking position in which then the respective access area is blocked by the shut-off. However, even if the fitter refrained from obstructing one of the passage areas through the associated shut-off means, however, the fall-resistance is nevertheless increased when the passage areas taper downwards in the vertical direction. In order to get through the passage area with your knees and feet, a little less space is needed than for the pelvic and abdominal area. In this respect, the fact that the passage areas preferably taper downwards in the vertical direction, the human anatomy is taken into account by only as much access width is provided as is absolutely necessary for the respective body region. As has already been explained above, the two access areas of the assembly basket according to the invention are preferably aligned at right angles to each other in order to leave or be able to access the assembly basket both in the longitudinal and in the transverse direction of a supporting framework tower to be erected. Accordingly, it is provided according to a further embodiment, that the first railing element is located on a side facing away from the two coupling devices of the mounting basket, whereas the second railing element is provided on one or more of the two coupling devices facing sides of the mounting basket.

For this purpose, for example, the peripheral portion of the floor covering, which faces the two coupling devices are formed by two right angles forming sides of the floor covering, and the peripheral portion of the floor covering, which faces away from the two coupling devices, can be formed by one side of the floor covering which preferably extends at an angle of approximately 45 ° to the two right-angled sides of the floor covering, which means that the floor covering has essentially the shape of a rectangle, preferably a square, from which a corner area has been removed at 45 ° , In this case, then extends the first railing element along the at an angle of 45 ° to the two forming a right angle sides of the floor covering, whereas the second railing element extends along the right angles forming sides of the floor covering.

In coupled to a support of a shoring tower state is thus the second railing element in the corner of the shoring tower, whereas the first railing element faces the interior of the shoring tower. This relative arrangement of the two With regard to the coupling devices, it is possible not only to orient the passage areas defined by the two railing elements in such a way that they are aligned at right angles to each other; Rather, by this relative arrangement of the two Gelanderele- elements with respect to the coupling devices, the passages are oriented so that they are aligned perpendicular to the respective neighboring scaffolding bar, so that the fitter is not hindered by scaffolding bars when leaving and entering the assembly basket. As explained earlier, it is during the construction of a

Supporting tower using at least two inventive mounting baskets required starting from one of the baskets each other lift the baskets and implement. In order to improve working ergonomics, the second handrail element can have two handling handles, wherein a handling handle is provided spaced apart from the passage areas delimited by the second handrail element above the upper free end of the second handrail element. By this measure, the distance of the handling handles is reduced to the heavy axis of the assembly basket, so that this tends to tilt to a slight extent when it is lifted and implemented using the handling handles.

As has also been explained above, during the construction of a shoring tower using at least two inventive mounting baskets, it is necessary for the mechanic to move from one of the mounting baskets to the other. Since the two mounting baskets can be located at different heights, it is provided to facilitate the change between the mounting baskets that the first railing element and / or the second railing element above the Flooring has a horizontal strut, which is preferably in a range between 15 to 35 cm, in particular preferably in a range between 20 to 30 cm above the floor covering. This strut can thus be used by the fitter as a step when changing between two adjacent mounting baskets so that he does not have to cope with the difference in height between the assembly baskets with a single step.

The present strut 15 to 35 cm, preferably provide in a range between 20 to 30 cm above the floor, proves to be advantageous because the mounting baskets are preferably hung with their coupling devices located in the supports rosettes, which usually have a vertical distance of about 50 cm to each other. Accordingly, the height difference between two adjacent assembly baskets is also about 50 cm. Due to the arrangement of serving as a tread strut in the specified areas thus this height difference is divided into two approximately equal areas, which can then handle the fitter without much effort. Although an embodiment will be explained in the following description, in which the mounting baskets are mounted with their coupling devices in rosettes located on the supports, it should be mentioned for the sake of completeness at this point that the mounting baskets on any other, provided on a support attachment means with the Support can be coupled, which are suitable for hanging the coupling devices. In addition, it should be noted that according to the following description, the mutual distance of the two coupling devices while approximately corresponds to the rosette spacing; However, the mutual distance between the two coupling devices can also differ from the rosette spacing, since the lower coupling device, for example, directly to a can support any support section to prevent tilting of the mounting basket.

In order to be able to couple the assembly basket in the desired manner with a support of a shoring tower, the two coupling devices are provided according to a further embodiment in each case at the free end of a laterally projecting over the railing assembly in the vertical direction supporting structures. Preferably, a first supporting structure below the floor covering extends laterally beyond the railing arrangement and carries a first of the coupling devices, whereas a second supporting structure extends laterally beyond the railing arrangement substantially in the plane of the floor covering or laterally and carries a second one of the coupling devices ,

The fact that the support structures in question extend laterally beyond the railing arrangement ensures that the assembly basket can be coupled to a support without the railing arrangement of the assembly basket colliding with the bolts of the supporting tower. Rather, because the supporting structures extend laterally beyond the railing arrangement, the railing arrangement has a certain distance from the adjacent structural bars, so that the diagonals of the latter can be mounted between them in the interior of the supporting frame tower.

Although the assembly basket according to the invention has two coupling devices, it is inventively provided that the vertical loads of the assembly basket are removed only via one of the coupling devices, preferably on the upper. For this purpose, the upper or second coupling device comprises a hook, via which the mounting basket on a support ze to be erected shoring tower can be hung. Below the hook, a Aufreitfläche is provided, which extends obliquely away from the region of the hook portion down. In other words, the Aufreitfläche thus forms an overhang, which faces the hooked on bending hook portion or the free end of the hook and tapers towards the top of this hook portion or the free end of the hook.

Now, if the mounting basket hooked on the hook of the upper coupling device to a support of a supporting framework tower to be erected, so rides the Aufreitfläche on a provided on the support rosette when the mounting basket is lowered while maintaining the entanglement. The vertical forces of the assembly basket are thus transferred by pressure from the Aufreitfläche on the rosette, at the same time the free end of the hook portion is subjected to bending. The Aufreitfläche comes here, for example at two defined locations in the form of two adjacent convex rosette sections with the rosette in Appendix, whereby an anti-rotation is achieved, which prevents the mounting basket can be inadvertently pivot about the support axis.

Since the hook of the upper coupling device comes to lie slightly above the escutcheon in the mounted state, there is basically the problem that without further precautions fastening wedges, via which the bars are wedged with the rosettes, can collide with the hook of the upper coupling device. To counteract this, the hook may have three 90 ° offset from each other recesses.

Through these recesses, the mounting wedges can thus pass unhindered without colliding with the hook. For the sake of completeness it should be mentioned at this point that the opening of the hook itself is in some way a fourth recess, so that Seen from this point of view, even four 90 ° offset from each other can have recesses so as to be able to attach in spite of the presence of a hook in all four directions extending latch on a rosette can.

In contrast to the upper coupling device, the lower or first coupling device has no hook, as it would be relatively difficult due to the weight of the mounting basket to make a hook connection simultaneously via two hooks. In order to facilitate the handling of the assembly basket, it is therefore provided according to a further embodiment that the lower coupling device comprises a vertically oriented mandrel whose free end is directed downwards. The mandrel of the lower coupling device serves only as a position assurance to prevent tilting of the mounting basket about a horizontal axis. In coupled with a support state namely the mandrel of the lower coupling device is threaded into an opening of a lower rosette, which is arranged below the upper rosette with which the Aufreitfläche the upper coupling device is in abutment, whereby ver a tilting of the mounting basket about a horizontal axis - can be prevented.

Although it would in principle be possible to remove the vertical loads of the assembly basket exclusively via pressure and bending over the upper coupling device, which would require a sufficiently rigid design of the second support structure. However, in order not to stress too much on bending the second support structure, it is provided according to a further embodiment, that the lower coupling means comprises a parallel to the mandrel running slide whose sliding surface faces the mandrel and spaced from it. In the assembled state, this sliding surface is then on the outside of the Rosette, in which the mandrel of the lower coupling device is threaded, so that the resulting from the vertical load of the mounting basket bending moment can be removed by pressure on the first support structure and train on the second support structure.

According to a further embodiment, the slide rail of the lower coupling device may further comprise a freely cantilevered end projecting beyond the free end of the mandrel and having a distance increasing from the longitudinal axis of the mandrel. In other words, in other words, the cantilevered end of the slide rail is convexly bent with respect to the mandrel and thus can be used as an insertion aid facilitating threading of the mandrel into the rosette, as will be explained in more detail below. According to a possible embodiment of the assembly method according to the invention, starting from the two assembly baskets coupled to the first supports, after installation of the second supports, a second framework level can be created with circumferential bars supported by the second supports. Alternatively, it would also be conceivable to lift at least one of the assembly baskets immediately after the installation of the second supports and to couple with one of these second supports.

According to yet another embodiment of the assembly method according to the invention, the first assembly basket is raised starting from the second assembly basket and coupled to a support of the second supports, preferably after the second assembly basket is raised starting from the first assembly basket and coupled with another support of the second supports. The assembly baskets are thus raised alternately starting from the respective other assembly basket and implemented as needed, so that the installer is always secured during the construction of a shoring tower against falling through the railing assembly of the mounting cage in which he is currently located.

The invention will now be described by way of example only with reference to the accompanying drawings, in which:

Fig. 1 shows a perspective view of the assembly basket according to the invention;

Fig. 2 is a perspective view of the upper Koppelein direction shows;

Fig. 3 shows a perspective view of the lower coupling device;

Fig. 4 is a perspective view of a shoring tower erected using four assembly baskets according to the invention; and

Fig. 5 shows a plan view of the shoring tower of Fig. 4.

Fig. 1 shows a mounting basket 10 according to the invention in a perspective view, which consists essentially of a walkable floor covering 12, a first railing element 14, a second railing element 16 and two mutually perpendicular to the plane of the floor covering 12 mutually offset coupling means 20, 22, via the Mon- 10 basket can be coupled with a support, not shown, of a scaffold or shoring tower to be erected.

The floor covering 12 is preferably made of aluminum sheet, which is provided with a non-slip coating or is designed as Riffelblech. The floor covering 12 has two sides 24, 26 forming a right-angled angle, above which the second railing element 16 extends. Furthermore, the floor covering 12 has a side 28 extending at an angle of 45 ° to the two sides 24, 26 forming a right angle, above which the first railing element 14 extends. The first railing element 14 is formed inter alia by a V-shaped bent tube which is welded in the region of its two free ends to the side 45 of the floor covering 12 which extends at 45 °. The second railing element 16 extends over the corner and is formed inter alia by three welded to the floor covering 12 railing rods 30, which are connected at their upper free ends via a likewise extending over corner handrail 32 with each other.

The floor covering 12 is thus surrounded in sections by the two railing elements 14, 16 extending above it. The two railing elements 14, 16 do not go over each other seamlessly, but are at the periphery of the floor covering 12 to form two access areas 15, 17 spaced from each other, through which a fitter can enter and leave the assembly basket 10. The two access areas 15, 17 are aligned at right angles to each other and extend parallel to the respective opposite sections of the second railing element 16. In particular, if four mounting baskets are used for non-square support tower tower sections, but assembly baskets can be used, each having only one passage area , in which case two different types of mounting baskets are to be provided, the passage areas have in different directions and are preferably aligned perpendicular to each other. 1, the first railing element 14 is slightly inclined and extends from the floor covering 12 in the direction of its free end obliquely outwards, with the result that the two access areas 15, 17 taper downwards, whereby the human anatomy is taken into account. In order for an installer located in the assembly basket 10 is not unintentionally by one of

Passage areas 15, 17 can get out of the mounting basket 10, two chains 36 are attached to one of the two legs of the first railing element 14 connecting handrail portion 34 whose respective free end can be hooked into each one provided on the handrail 32 of the second railing element 16 hook 38 so as to shut off the respective access area 15, 17.

The two coupling devices 20, 22 shown in FIG. 1 and more particularly in FIGS. 2 and 3 are provided on the side of the assembly basket 10, where the second railing element 16 is located, which means that the first railing element 14 at the two Coupling devices 20, 22 opposite side of the mounting basket 10 is provided. Specifically, the two coupling devices 20, 22 are in the region of that corner of the floor covering, which is formed by the sides 24, 26. The upper and second coupling device 22 has a hook 40 formed of a metal plate, which serves to hang the mounting basket 10 on a support of a supporting framework tower to be built, for which purpose the hook 40 behind the support and partially surrounds. As can be seen in FIGS. 1 and 2, the plate forming the hook 40 has three recesses 108 offset from one another at 90 °. The opening which serves to hook the hook 40 on a support, so to speak, also forms a recess 108, so that the hook 40 has, as it were, four recesses 108 offset from one another by 90 °, two of which are mutually opposite recesses 108 parallel to the longitudinal direction of a the two mutually perpendicular sides 24, 26 of the floor covering 12 are aligned.

The hook 40 is welded at the free end of a laterally projecting beyond the second railing assembly 16 supporting structure 44, which in turn consists of a welded to the floor covering 12 plate portion 46 and two each provided with a recess stiffening ribs 48 which on the underside of the plate portion 46 and on the other hand are welded to an extended portion 54 of the middle railing rod 30 of the second railing element 16, whereby viewed in cross section, a cantilevered Pi carrier is formed. At the free end of the stiffening ribs 48 a Aufreitplatte 50 is welded, which is inclined so that its outwardly facing surface 52 forms an overhang. As can best be seen from FIG. 2, the treading plate 50 or its tread 52 is below the hook 40, wherein the tread 52 is inclined so that it slopes away from the region of the free hooked portion which is subjected to bending. extending down the free end of the hook 40.

The first coupling device 20 (see FIGS. 1 and 3) is perpendicular to the plane of the floor covering 12 in comparison to the second coupling device 22 down and is located at the free end of a first support structure 42 which extends laterally below the floor covering 12 via the second railing assembly 16 to the outside. The support structure 42 is formed by extended portions 54 of the three railing bars 30 of the second railing member 16, which are bent to extend laterally outwardly beyond the second railing assembly 16 and to a common point where they are welded together. More specifically, the extended portions 54 of the two outer railing bars 30 are welded to a vertically extending portion of the extended portion 54 of the center railing bar 30, this vertically extending portion of the extended portion 54 performing the function of a slide rail 56, the purpose of which will be described more fully hereinafter will be received. The slide rail 56 forms on the side opposite to the side on which the two extended portions 54 of the two outer railing bars 30 are welded, a sliding surface 58, to which a downwardly cantilevered mandrel 60 is welded, which is parallel to the slide rail 56 runs. As best seen in FIG. 3, the slide rail 56 has a downwardly cantilevered end 62 which projects beyond the free end of the mandrel 60 and progressively extends away from the longitudinal axis of the mandrel 60 in the direction of its free end. When coupling the assembly basket 10 according to the invention with a support 100 (see FIGS. 2 and 3) of a shoring tower, the procedure is such that initially the hook 40 of the upper coupling device 22 is hooked onto a support 100 without at the same time being coupled to the lower one Coupling 20 with the support 100 must be respected. After the mounting basket 10 via the hook 40 with the Support 100 was hooked, then the mounting basket 10 is lowered while maintaining the Hakverbindung parallel to the support 100, wherein due to the conical shape of the free end of the mandrel 60 and the convexity of the free end 62 of the slide 56 does not have to take care that the Mandrel 60 is exactly aligned with the opening 104 of a lower rosette 102, in which it is to be threaded. Rather, serves during lowering of the mounting basket 10, the convex free end 62 of the slide 56 as an insertion aid for the mandrel 60, as this comes during the lowering of the mounting basket 10 with the convex portions 106 of the lower rosette 102 into abutment (in FIG .. 3 the concealed convex portion 106 indicated by dashed lines), which are formed on the outer periphery of the lower rosette 102 adjacent to the opening 104. When the assembly basket 10 is then further lowered, the free end of the mandrel 60 is inserted into the opening 104 due to the convexity of the free end 62 of the slide 56, thus providing the free end 62 of the slide 56 as an insertion or threading aid. In the lowered state, the slide rail 56 is then located on the concave lying between two adjacent convex peripheral portions 106

Section 105 of the lower rosette 102, whereby the mounting basket 10 is supported on the support 100 in the horizontal direction. In contrast, the mandrel 60 is free of forces in the lowered state of the mounting basket 10, which later lifting the mounting basket 10 is facilitated.

During lowering of the assembly basket 10 rides the Aufreitfläche 52 of the upper and second coupling device 22 on an upper rosette 102 of the support 100 (see Fig. 2) whereby the vertical loads of the mounting basket 10 via pressure in the rosette 102 and from there into the support 100 are removed. The Aufreitfläche 52 rides on two adjacent hard convex peripheral portions 106 of the rosette 102, thereby ensuring that the mounting basket 10 can not rotate about a vertical axis. Thus, the drive-up plate 50 of the upper coupling device 22 not only serves for load transfer, but also as an anti-rotation device.

Although not shown in FIG. 2, in the four mutually offset by 90 ° recesses 107, which are formed in the equally offset by 90 ° to each other convex portions 106 of the upper rosette 102, the bolt of a supporting tower to be built with their are hooked free ends and wedged with wedges, which then protrude from the upper rosette 102 parallel to the support 100 upwards. So that these fastening wedges, not shown, do not collide with the hook 40 of the upper coupling device 22 during the lowering of the assembly basket 10, the three or four recesses 108 offset from one another by 90 ° are formed in the hook 40. Because of these recesses 108, the fastening wedges can pass unhindered during the lowering of the assembly basket 10, without colliding with the hook 40.

The construction of a supporting tower using four assembly baskets 10 according to the invention will now be explained below with reference to FIG. 4. FIG. 4 shows a snapshot during the construction of the shoring tower, which has a rectangular geometry in plan view (see FIG. 5), wherein the shorter side is approximately 1.5 m and the longer side is slightly more than 2 m long , The assembly state according to FIG. 4 was created by firstly producing a first framework level with circumferential upper bars 120, 122 from the bottom, which are carried by first supports 100 located in the corners of the first framework level. At the foot are the Supports 100 are also connected to each other via lower bars 120, 122, wherein these foot-side bars 120, 122 are connected to the head-side and upper bars 120, 122 for stiffening purposes via diagonal 124 with each other.

After the first framework level has been created from circulating bars 120, 122 carried by posts 100 located in the corners of the first framework level, a first assembly basket 10 is coupled to one of the first posts 100 in the manner previously discussed so that the railing elements 14, 16 of the assembly basket 10 extend beyond the first frame level or above the upper bar 120, 122 of the first frame level upwards. Subsequently, a second mounting basket 10 is then coupled analogously to the first mounting basket 10 with another of the first supports 100, which is closest to the support 100, with which the first mounting basket 10 has been coupled. In other words, therefore, two mounting baskets 10 according to the invention are attached to those first supports 100 which are connected by one of the shorter bars 120, as is the case with the two assembly baskets 10 shown on the right in FIG. Since FIG. 4 is a snapshot during the erection of the shoring tower, the assembly baskets 10 in question may have been previously coupled in a corresponding manner slightly further down to the respective first support 100, from where they are to be used by a mechanic, which is located in each one of the mounting baskets 10, alternately raised and coupled again with the respective support 100 in the manner previously explained.

In addition to the two right-hand mounting baskets 10 of FIG. 4, two further mounting baskets 10 are coupled in a corresponding manner to the other two first supports 100, of which in FIG. 4 the rear mounting basket 10 already above the upper end of the first support 100 has been lifted and coupled to a second support 101, which is supported by the underlying first support 100.

As can be seen from the two right-hand assembly baskets 10 of FIG. 4, the fitter in the front assembly basket 10 is already above the first framework level, which is defined by the upper bars 120, 122, from which the second scaffolding level is conveniently located including the required second supports 101 to install. However, the installer is not in the desired way in the fall, because he is within the assembly basket 10, the sections of surrounding railing assembly 14, 16 secures him at any time during installation against falling.

In order to be able to install further scaffolding levels including the supports required for this purpose, the two respectively immediately adjacent mounting baskets 10 are lifted by one assembler alternately starting from the other assembly basket 10 by a respective rosette distance and again coupled to the respective support 100, 101. The installer passes from one mounting basket 10 into the other by hanging the shut-off chains 36 and passing through the immediately adjacent access areas 15, 17 of the two assembly baskets 10. Since in this case he has to overcome a vertical distance which corresponds to a distance between the rosettes, a horizontal strut 33 is provided on the second railing element 16 in a range between 15 and 35 cm, preferably in a region between 20 and 30 cm above the floor covering 12, which the installer can use to overcome the difference in height between the two mounting baskets 10 as a step, so that he can easily get from one to the other mounting basket 10. In order for the installer shown on the left in FIG. 4 to be able to raise the assembly basket 10 immediately adjacent to him, it is necessary for him to bend down over the blocking chain 36 in order to be able to grip the assembly basket 10 located underneath. So that the installer does not have to stoop down too much in this case, the assembly basket 10 according to the invention has two handling handles 64, wherein a handling handle 64 is spaced apart from the access areas 15, 17 bounded by the second railing element 16 above the upper free end of the second railing element 16 is provided on the same (see in particular Fig. 1). The installer can thus grasp the lower assembly basket 10 on the one hand on one of the two handling handles 64 and on the other hand on the V-shaped bent portion 66 of the first railing element 14, which again the occupational safety and ergonomics is improved. In addition, due to the fact that the two handling handles 64 are displaced in the direction of the axis of gravity of the assembly basket 10, the assembly basket 10 does not tilt when it is raised, so that the installer does not have to counteract unwanted tilting of the assembly basket 10 by additional effort.

For the sake of completeness it should be mentioned at this point that in the event that no side length of the shoring tower should be longer than 1.5 m, the construction of the shoring tower could be carried out using only two assembly baskets by a single mechanic, in this case If the two baskets not only successively raised but also be implemented, so as to be able to reach the respective mounting area comfortably. In this conversion process, starting from a mounting basket, the respective other assembly basket is released from the support, with which it is coupled, and then hung in the diagonally opposite support or coupled with this. Then then the fitter can go in this way converted assembly basket and from this then also those mounting basket in a corresponding manner diagonally implement, in which he was previously.

In summary, it should therefore be stated that for the first time a mounting cage is provided by the present invention, the structural safety and ergonomics of the construction of a scaffold or a supporting tower significantly and for the installer practically mandatory and without realistic bypass options is improved.
