Description

The invention relates to a collapsible hanging scaffold, in particular for shipbuilding purposes, with vertical, parallelogram-like displaceable and tiered one above the other Scaffolding panels made of crossbars and hanging rods articulated to these at both ends, whereby the top and bottom crossbars can be connected to the building wall and in the topmost scaffolding bay a variable-length, detachable diagonal bar is arranged in each case.

In a known hanging scaffold of the generic type (patent specification 26 176 of the Office for Invention and patents in East Berlin) with several working platforms arranged one above the other are the hanging rods and those for adapting to the outer shape of the object to be scaffolded in each Floor provided, variable-length diagonal bars with vertical tabs, which the crossbars limit on both sides, articulated, the diagonal bars designed as tension straps are and have clamping elements. The tabs have the purpose of collapsing the frame a different length, with one at each of the ends of the crossbars lying one below the other Alternate a long flap and a short flap. It is on Cirund this type of training possible to adapt the scaffolding to the external shape of the object to be scaffolded and also the scaffolding Not in use, to be folded from bottom to top. This is the result of the erection and folding of the hanging scaffolding. Difficulty insofar as when building the scaffolding the one pulling up the scaffolding: the crane has to drive continuously forwards and backwards. an unintentional Inclined corner of the framework, where /.

to avoid. When folding the scaffolding «Ind furthermore several workers are necessary for the proper location of the scaffolding parts must ensure the required lengthy and labor-intensive Assembly and disassembly is explained by this * ,, that with the known scaffolding cmc zu.l - zag-shaped posture of the individual Gerustfekki vorKCSL-l.cn is. namely in each case a Querriegcl is retained in its position and then shifted to one or the other side in this way becomes that the diagonals egg strivings become slack The zigzag folding of the Geriisu also harbors a considerable risk of accidents: ür the workers who organize the individual scaffolding levels, since the crane operator is often the workers cannot see and is dependent on a show of hands.

The object of the invention Ix on the other hand, in the case of a scaffolding, it says:;, Consideration / u zk-honden type through improved addition Reduction in assembly and disassembly, saving time and labor.

Starting from a hanging scaffold of the cingan: mentioned type, this object of the invention is achieved . follow solved by the fact that each cross-section at the end facing the building has a redirected and at its other end an 11. · Has an upward-facing set, each carrying a joint eyelet, for connecting the hanging rods. This measure according to the invention is achieved. that the framework can be folded up by a single folding path, a flat structure hanging in an approximately vertical plane, and transported away in this form. Only one worker is required for the assembly and disassembly, who is solely responsible for hanging and unhooking the crane hook or hooks. Another advantage of the scaffolding according to the invention is that each attachment of the crossbar has only one eyelet for connecting the hanging rods.

According to a further feature of the invention is it is provided that the crossbars of two adjacent scaffolding fields are firmly connected to working platforms, thereby the very wage-intensive work of laying planks or decrease is no longer necessary.

Finally, the invention is also characterized in that the diagonal bar is resistant to tension and compression is trained. The arrangement of such a diagonal bar, which is only provided in the top scaffolding bay serves the purpose of using the new type of scaffolding for scaffolding such objects can, which have a bulging outer skin protruding outwards, with the framework then in side view seen approximately assumes a circular arc shape.

In the drawing, an exemplary embodiment of the invention is shown. It shows

Fig. I a collapsed hanging scaffold in the Side view and

Fig. 2 shows the same hanging frame in the position of use.

The hanging scaffold essentially consists of the Hängesäbcn 3, 4 and 4, which are designed as tubular struts the Qiierriegeln S. Hiingest rods and crossbars are in Gclenkösen 6 non-articulated and form rectangular in the position of use or with an inclined wall of the building 100, /. B. on a ship's wall, par-

., 'ldogram-shaped scaffolding fields, with at least /v.ei scaffolding fields are t.ordered one below the other. As the drawings show, the hinge eyes 6 are not in the corners of the scaffolding fields, but are offset from one another. For this purpose, the cross nails 5 by their Thread arranged, oppositely directed, hook-shaped Approaches 51, in which. End areas which are (hinge eyes 6, Z-shaped. When folding of the hanging frame, a certain space remains between the hanging rods 3, 4 and the crossbars 5 (Fig. 1). This space is enough to allow on the crossbars 5 by means of Maliern 71 screwed-on working platforms 7 to take between them.

A suspended crag is formed, among other things, that two scaffolding fields, consisting of crossbars 5 ι · ,, d hanging rods 3, 4 are connected to one another by screwing on the working platforms 7. Of course, instead of two framework fields, three or, under certain circumstances, several can also be added be combined in a unit, as well as adapting the number of floors to the respective requirements is.

The drawing also shows that the hinge-like connection between crossbars 5 and hanging rods
