Description

Foldable room scaffolding

The innovation relates to a so-called room scaffolding, i.e. a scaffolding that is primarily intended for indoor work is.

The scaffolding of this type has so far been assembled from individual elements in the same way as the one on the outside of the building erected scaffolding, i.e., for example, from two scaffolding forming the narrow side of the scaffolding Vertical frames, which are interconnected by longitudinal grooves; el and be connected by diagonal braces and in their upper Crossbars, for example, scaffolding frames of a known type are used, which are used to lay gangplanks. jJiece Scaffolding can of course be made as high as desired by stacking several vertical frames,

be attached to which backrests or railings "attached can be. A large number of different components required, which are put together in a relatively lengthy operation so that a considerable loss of working time has to be accepted. In addition, the transport f these items awkward.

It has already been suggested for the construction of such Scaffold a large number of core parts into units unite and connect the longitudinal bars and diagonal struts with the vertical frame so firmly that de.ss them in one Can be pivoted in the vertical plane and the scaffolding can be collapsed. However, it is not possible to find a solution for this to find in which neither the longitudinal bars nor the diagonal struts are not connected to one of their ends by a coupling to the other scaffolding elements must be connected. It has therefore already been suggested that such compounds should be used Units to provide the struts or lugs with joints, which allow them to be bent in a vertical plane. However, these solutions are technically complex and expensive, so that such scaffolding is disproportionately expensive. In addition, when these frameworks are folded together, there is a shift of the scaffolding into itself and it is not possible when the scaffolding is folded, at the same time

to set up borrowed vertical elements on the floor, so that the erection of such a scaffolding is made considerably more difficult

and requires a considerable amount of time.

It is now to eliminate these difficulties as well it has been proposed to carry out a room scaffolding in such a way, that it is designed to be foldable in such a way that two vertical frames forming the two narrow sides of the erected scaffolding with an atis also formed as a Yertical Rare Longitudinal part are connected by hinge-like joints, so that the two form the narrow side of the frame Vertical frame can be pivoted against the longitudinal frame Terseh can and the frame stisaamengefold for transport

The task of the fire is now to create a framework of the suletst described Kind of so improve that it is the case with Sranspori; occupies a minimum of space. To this end, will a Zimuergerüüt, in which each of the two the narrow sides the vertical frame forming the genist can be pivoted to the set up at. Scaffolding lengthways part by means of hinges or are articulated in another suitable manner, designed in such a way that the longitudinal part consists of consists of at least two single frames, which are hinged in a horizontal direction, drawn on the erected scaffolding can be pivoted against each other by at least 180 °.

In the next section of the haying process, the scaffolding will be reinforced & erüstrahiaen or scaffolding frames, for example made of Hola cavity plates, inserted, which are on the same side as Ijaufflächen serve \ md as they are from the external scaffolding "already are known. Lie dimensions of the G-scaffold must then accordingly chosen and the scaffolding designed so that such G-erüstran_entafeln without difficulty can be used.

Sin G-rüst of this kind has the advantage that it is easy to use Can be set up in a way that always includes all

vertical scaffolding elements stand up on the floor that it on the other hand, it can be folded up in a very small space, as the lengthways element is also can be folded to a sufficiently small dimension. In this way one achieves that scaffolding of this kind even housed in the trunk of a passenger car can be.

In the following, based on the accompanying drawing, an exemplary embodiment for such a room frame according to FIG Innovation are described without, however, excluding a different implementation of the inventive concept shall be. In the drawing show: ρ

Vertical frames 1 and 2. Each of these Yertilcalrahmen 1 and 2 is composed of the spars 11 and 12, for example by the rungs-like and in relatively small distance from each other arranged crossbars 13 are connected to one another. The crossbars 13 are inseparably connected to the spars 11 and 12, for example by welding.

The bars 12 of the two frames 1 and 2 are connected to the longitudinal part 3 by means of the hinges 14 provided thereon swiveling verbundsn. These hinges each grip like a clamp around the bars 12 and are preferably se arranged that they slide for example through the top and bottom crossbars 13 of each frame hindered from above or below.

In the example chosen, the longitudinal part 3 consists of two individual frames 3a and 3b, each of which consists of There are two longitudinal bars 15, which are connected to one another by two perpendicular sLarre connecting struts 16 and are stiffened by a diagonal strut 17. The ends of the longitudinal bars 15 of each of these frames 3a, 3b protrude the attachment points of the connecting struts 16 hinaui. Those Ends 3 a are movably connected to these, for example

by welding, firmly connected. The other üaiden 3a £ and 3bp are connected to each other via a hinge 21 so that that they 'can be rotated against each other about a vertical axis. To set up the scaffolding, the two Frame 3a and 3b rotated against each other so that they are within lie on one level and in this way the longitudinal part

make it 3. The joint 21 is designed in such a way that / in the position in which the two holers 15 form an angle of 180 °, engages and is released by a special measure, for example by operating a lever 22 can. The two frames 1 and 2 forming the narrow sides are brought into a position by pivoting in which they are at right angles to the rope 3 forming the long side. Then a scaffolding frame panel 4 is placed on two rungs 13 corresponding in height to one another (not shown in FIG. 1, see FIG. 2). The length of the backbone Rahn Table 3 corresponds to the distance between the two narrow side forming frame 1 and 2, and the total length of the longitudinal side forming member 3. T) Ie scaffolding frame panel 3 is placed in the usual scaffolding manner by means of its fastening elements 18 on the crossbar 13 .

In the example shown, it is assumed that dat> Scaffolding without castors at the lower ends of the spars 11, 12 is carried out. Of course it is also possible * ii to provide the bars 11 and 12 with such.

In order to be able to expand the scaffolding upwards as desired, are on the upper ßiden of the spars 11 and 12 tube connector 19 is provided, on which the lower Biden of the spars of a similar Scaffolding can be attached. Of course, such scaffolding can also be designed at different heights be used, for example, in cases in which the tread on the top crossbars of the two narrow Pages 1 and 2 is placed in order to be able to attach a railing or a backrest.

In Pig »2 there is a framework that is different from two such high, foldable ornamental scaffolding elements formed by clipping is presented, layed out. Here are the lower sides of the spars of the upper frame element at 20 on the Attached ends of the spars of the lower frame element Plug connector 19 (see Fig. 1). Ji e individual Parts of the upper lower frame element are identified with the same reference numerals as the corresponding ones Part of Fig. 1, but these reference numbers are preceded by a prime (').

Instead of having a detent in the binding position (180 °), which can be unlocked e.g. by pressing the lever, it is possible to design the joints 21 so that they have, for example, several locking points or in any Position, for example by means of a clamping device, can be set

be able. In this way it is then possible to create a scaffold possibly to give an M-shaped position in plan view by laying the longitudinal connection in a bent position, similar to that shown in Fig./, whereby a smaller distance is reached between the two narrow sides 1 and 2, which is then e.g. adapted to a shorter form of the scaffolding frame panels Can be used if, for example, several standard lengths are provided for this.

The room scaffolding according to the innovation can be made of metal frames, whereby, for example, the tubes 11, 12 forming the vertical spars can have a larger diameter than the crossbars 13 or the connecting struts M and the diagonal struts 17 Suitable profiles can be used, such as U, T or I profiles. There are also a wide variety of options for hanging the scaffolding frame panels. For example, the frame panels can be provided with fittings at their ends, which grip around the tubular crossbars and are shaped so that after these fittings have been inserted, the crossbars are reliably prevented from sliding or sliding out of the hook. On the other hand, it is also possible to use an upwardly open U-profile with straight or angled flaps for the cross bar 13, into which the hook-shaped fittings engage. Instead of two, the

both corners of a narrow side of the scaffolding frame panel provided fittings a continuous profile attached to this narrow side can be provided, which is designed in this way is that it encompasses either the tubular crossbars or engages in a U-profile. Instead of a U-profile the QLier ledger can also be made from a T-profile with an upward side directed web exist, the web for hanging the fittings or on the front side of the frame panels attached profile is used.

Furthermore, it is also entirely possible to use the crossbars Provide special fastening elements, such as pins or Tilting pins into the eyelets attached to the scaffolding frame panels be hooked. In this case, the crossbars forming profiles can be arranged so that they are with a smooth surface, for example the web of a U-profile, face upwards, with the fasteners on this Surface are fastened for example by welding, screwing or riveting. When the crossbar is indicated in the saeben Way show a curved or flat surface pointing upwards, holes or can also be used in this surface Slots can be provided into which hooks attached to the end faces of the scaffolding frame panels engage. It is so it is possible to adapt the scaffolding to any system for external scaffolding, so that in connection with the scaffolding according to the Neuerting elements of the system in question

- 11 can be used for external scaffolding.

In Figure 4 the scaffold is in a semi-susceptible folded condition in plan view; shown to see below in which Way the process of 2tosanmenfolding is carried out. Fig. 5 shows the folded frame. It is easy to see that the skeleton is in a siisaiinnengex ^ old Condition outside of extremely small space.

In the example described in the door, it was assumed that the part 3 forming the long side consists of two individual frames 3a and 3b connected to one another by hinges 21. Of course, it is also possible to divide the long side out of more than two such individual frames susaiasiensrusetsen, for example in order to be able to fold longer Q-frames in this way. If so, is it an advantage, for example, in the middle of the middle frame to attach a downwardly v / ironing stub on the lower longitudinal ledger _? who stands as a foot on the ground.

Of course, the possibilities described above are only examples and it is possible to use a Simmergerüst in accordance with the innovation concept also in others V / form out. For example, the two can use the Longitudinal bars 15 'forming the backrest instead of the parts 16 'and 17' in another way, for example by a
