Definitions

  • the invention relates to a method for dismantling slab formwork formed from a plurality of formwork panels, in particular which can be assembled at the edges, which are accessed with a lifting device, released from the composite of the slab formwork, let down and set down.
  • the invention further relates to a device for striking ceilings and / or for carrying out the above-mentioned method, with a hoist with a height-adjustable arm or the like, on the free end of which a holder for detecting formwork parts is arranged.
  • a stripping device detects formwork parts, lowers and tilts into an inclined position so that the entire device can then be moved into the open through door openings.
  • the device is designed as a vertically variable length mast, which has a holder for the formwork panels at its end.
  • Such a support mast which can often be extended in the longitudinal direction over considerable heights, is not only difficult to manufacture, but also sensitive on the sliding surfaces of the telescopic rods which can be pushed into one another.
  • this support which can be extended vertically in its longitudinal direction, must be very stable if sufficiently large formwork parts are to be able to be gripped and even tilted without the sensitive, mutually guided parts of the longitudinally adjustable support suffering. Above all, dismantling an inclined formwork wall is problematic and also dangerous. On the other hand, it is not possible to completely put down the formwork parts fastened to the height-adjustable support without further aids, because this support has a minimum height when retracted.
  • the method according to the invention consists in the fact that formwork parts consisting of several formwork panels after detachment from the ceiling formwork partially, at least half of its extent parallel to a swivel axis, lowered and turned with its underside upwards and then finally stored. Now they can be disassembled on their upward rear side, whereby no gravity, supporting forces or the like is more effective on the formwork part. There is also no danger to the person performing the dismantling, since the formwork parts are already on the floor.
  • a device for stripping ceilings and / or for carrying out the aforementioned method with a hoist with a height-adjustable arm or the like, at the free end of which a holder for detecting formwork parts is arranged can be characterized according to the invention in that the height-adjustable arm as is designed pivotable extension arm and the holder for the formwork elements is in turn pivotally mounted.
  • the height-adjustable arm as is designed pivotable extension arm and the holder for the formwork elements is in turn pivotally mounted.
  • extension arms can be designed sufficiently stiff to handle the corresponding weights, while at the same time by the one-sided pivot bearing of such an extension arm z. B. enough space for the turning movement according to the invention is created in a middle position below the free end, which is not given on a vertical support arm.
  • a device designated as a whole with 1 is used for stripping and at least for preparing the dismantling of formwork panels 2 of a slab formwork, whereby it should be avoided that the individual formwork panels must be released from the formwork assembly in a dangerous manner at great heights.
  • the device 1 has a pivotable and thus with its free end 3 height-adjustable arm 4, which has a pivotally mounted bracket 5 for the formwork parts or elements 2 at its free end 3. 1 and 4 it is indicated how a formwork structure 2 consisting of several formwork panels is attached to this holder.
  • the extension arm 4 can be placed vertically or almost vertically, while the holder 5 retains its approximately horizontal position and can reach under a formwork area. Now couplings or other fasteners can be actuated, after which the formwork area to be released is separated at its edges from the rest of the formwork. For this purpose, only a relatively few connections can be made at a greater height compared to the overall connection points of the formwork panels. Thereafter, the entire formwork, formed by swiveling the extension arm 4 downward, can first be partially lowered, namely by at least half of its extent parallel to the swivel axis 6 of the extension arm 4. In the exemplary embodiment according to FIGS.
  • the pivotable holder 5 can then be turned around in this position independently of the extension arm 4 by approximately 180 °, so that the underside of the formwork 2 is turned upwards. Thereafter, the formwork structure by further lowering the off low-legged finally put down and disassembled on the rear facing upwards. A large part of the disassembly takes place in a safe position on the floor.
  • the formwork 2 is turned directly on the hoist 1 after a partial lowering and then finally lowered.
  • the holder 5 as a holding head or the like.
  • the swivel arm 4 can be swiveled by at least 180 ° with respect to a horizontal position in order to be able to carry out the desired complete reversal.
  • the pivot axis 6 of the extension arm 4 and that of the holding head 5 are arranged in parallel in the exemplary embodiment.
  • the holding head 5 can be turned around an axis which extends approximately in the direction of the extension arm 4.
  • a hoist in which the holding head 5 is carried by an at least two-arm extension arm 4 a, the two spars 7 have parallel pivot axes and lead to a parallel displacement of the holding head 5 when pivoting the entire arm 4 a.
  • pivoting means in the form of working cylinders 8 are provided for the extension arm 4 or 4 a and the holding head 5, which, however, can also be designed as lifting spindles.
  • the pivoting means for the extension arm 4 on the one hand and the holding head 5 on the other hand can be actuated independently of one another, while in the exemplary embodiment according to FIG of holding Head 5 leads, whereby this maintains the aforementioned parallel position.
  • the extension arm 4 is adjustable in length, in particular can be extended telescopically. Compared to a vertical support arm that can be extended telescopically to reach the ceiling, this extension option need not be provided with such careful tolerances and, above all, not with drive means. Rather, nested pieces of pipe with cross holes 10 and corresponding cross bolts can be used, so that overall a very simple device is created, in which heights of different sizes can be taken into account in a simple manner.
  • the holding head 5 can engage with its central support 5 a, for example by means of a thread 11, adjustable in height on a shoulder 12 of the pivot bearing 13 at the free end 3 of the extension arm 4.
  • a thread 11 adjustable in height on a shoulder 12 of the pivot bearing 13 at the free end 3 of the extension arm 4.
  • the pivotable extension arm 4 or 4 a is mounted on a frame 14 which is respectively movable in the exemplary embodiment, wherein this movable frame 14 can have steerable wheels 15, preferably provided with caster.
  • this movable frame 14 can have steerable wheels 15, preferably provided with caster.
  • shuttering of ceilings can be facilitated under certain circumstances by mounting larger formwork areas on the floor and then using the device to detect, turn and position them.
  • the device according to the exemplary embodiment according to FIG. 3 includes, according to the invention and according to a feature of the invention of its own worthy of protection, a turning device 1 6 shown in FIGS. 4 to 6, which is arranged in the region of the pivotable extension arm 4 a and supports 17 for has to be attached to the formwork 2 pivot pin 18.
  • a turning device 1 6 shown in FIGS. 4 to 6 which is arranged in the region of the pivotable extension arm 4 a and supports 17 for has to be attached to the formwork 2 pivot pin 18.
  • One of the supports 17 and a pivot pin 18 are shown separately in FIG. 6.
  • This turning device 16 which also belongs to the invention and on which formwork 2 can also be placed with the aid of a device according to FIGS. 1 and 2, is formed by a scaffold consisting of two independent parts, which is provided with a chassis 19 with preferably steerable wheels 20 is.
  • a formwork panel structure 2 can also be transferred to another location and finally dismantled there or used again.
  • the turning device 16 itself as well as the lifting device of the device 1 can be easily handled adapt to the different places where formwork or possibly formwork work has to be carried out.
  • the device according to the invention includes the rail 21, clearly shown in FIG. 6, which can be attached to the edges of the formwork 2 to be handled, with a bolt 18 projecting from the formwork panels parallel to the formlining, such rails 21 with bolts 18 being attached to two mutually opposite edges are, which then fit into corresponding receiving openings or supports 17 of the turning device 16. If, for example, two such turning devices 16 are juxtaposed, the bolts 18 projecting from one another can be inserted into the corresponding supports 17, so that the formwork 2 can then be turned.
  • the pivot pins 18 which can be attached to the formwork panels have at their free end a head 21 a which can engage behind the end face of the receiving openings 17 in the use position. This is clear from FIG. 6 in connection with FIG. 4, where the arrangement of a suspended formwork 2 is indicated in the upper area in dashed lines.
  • the pivot bolts 18 can have on their head 21a and / or on their area 22 facing away from the head a cone directed towards the actual bearing point, which causes an automatic centering between the bolt 18 and the turning device 16 when inserted.
  • the two turning devices 16, which together receive a formwork structure 2 can be moved, because they can follow the forces exerted by the cone and gravity well.
  • the bearing points or receiving openings 17 of the turning devices 16 are adjustable in height and preferably adjustable and fixable by means of working cylinders 23.
  • the bearing points 17 for the pivot bolts 18 of the turning devices 16 are guided in a height-adjustable manner in a turning frame 24 and that 17 tension elements 25, in particular chains, attack these bearing points Lead via an upper deflection wheel 26 to the movable part, namely the piston rod 27 of the working cylinder 23. If this working cylinder is now actuated, the lifting movement is practically doubled compared to its stroke, and the bearing points 17 can also be lowered to the floor below the highest position of the piston rod.
  • the chain 25, which is anchored at a medium height, for example, to a plate 28, then hangs downward in the retracted position of the working cylinder via the correspondingly now lower deflection wheel 26.
  • the one or more working cylinders 23 and also 8 of the turning devices 16 and the pivotable cantilever arm 4 can be actuated with a hand pump, so that the whole device becomes independent of any power connections.
  • the turning devices 16 in the exemplary embodiment consist of two frames that can be set up mirror-symmetrically to one another and moved independently of one another facing feet 29 or the like.
  • These support feet 29 are lower than z.
  • B. is a dumbbell or the like. So that 29 square timbers can be placed parallel to these supports, on which then the formwork structure 2 detected by these turning devices 16 can be finally deposited after its turning. The turning devices can then be pulled out on both sides and moved away and used for further use.
  • the formwork panels 2 with the hoist 1 are first placed on these turning devices 16, turned on them and then finally lowered.
  • the turn itself can be done practically by hand because the formwork structures can be rotated very easily due to the centrally arranged bolts 18.
  • the bolts 18 can be fastened with the aid of keyhole-like perforations 30 which match corresponding perforations on the front edges of the formwork panels 2 and allow the use of the same fastening elements with which the formwork panels 2 can also be coupled to one another.
  • a great advantage of the device according to the invention is also that, with the aid of the pivotable holder 5, switchboards can also be removed from or attached to a switched wall, the holder then being used pivoted by 90 ° with respect to the illustration in FIG. 1.
  • the formwork panels can be removed directly from the wall and lifted into the area of the ceiling.
  • the device according to the invention not only simplifies the removal and removal of formwork from ceilings, but also, in particular, relatively high walls, and the upper formwork panels of a wall can be immediately implemented in order to form a ceiling located above it.
