Definitions

  • the invention relates to a method for disassembling formwork units consisting of a plurality of formwork panels, which can be assembled in particular at the edges, from ceiling formworks, which are accessed with a hoist, released from the composite formwork of the ceiling formwork, pivoted down, and set down.
  • the invention further relates to a device for stripping ceilings, in particular for carrying out the above-mentioned method, with a hoist with a height-adjustable arm or the like.
  • a pivotable holder for detecting shuttering panel units consisting of a plurality of shuttering panels is arranged at the free end of which a pivotable holder for detecting shuttering panel units consisting of a plurality of shuttering panels 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 is 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 the shuttering units are partially lowered after being removed from the slab formwork, at least by half of their extent parallel to a pivot axis, and are turned upside down and then finally deposited. Now they can be dismantled on their upward rear side, whereby no gravity, supporting forces or the like is any longer effective on the formwork panel unit. There is also no danger to the person performing the disassembly, since the formwork panels are already on the floor.
  • a device for stripping ceilings in particular 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 pivotable holder is arranged for detecting formwork units consisting of several formwork panels, can be characterized according to the invention in that the height-adjustable arm is designed as a pivotable cantilever arm and the holder for the panel units is in turn pivotally mounted.
  • the height-adjustable arm is designed as a pivotable cantilever arm and the holder for the panel units is in turn pivotally mounted.
  • Such cantilever arms can be designed to be sufficiently rigid to be able to handle the corresponding weights, while, at the same time, due to the one-sided pivot bearing of such a cantilever arm. B. enough space for the reversing 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 cantilever arm 4, which is therefore adjustable in height with its free end 3, and which has a holder 5 for the control panels 2, which in turn is pivotably mounted on its free end 3. 1 and 4 it is indicated how a formwork consisting of several formwork panels 2 is attached to this holder 5.
  • the cantilever arm 4 can be placed vertically or almost vertically, while the holder 5 maintains its approximately horizontal position and can reach under a formwork area. Now couplings or other fasteners can be actuated, after which the formwork panel unit to be released is separated at its edges from the rest of the formwork. For this purpose, in comparison to the total connection points of the formwork panels 2, only relatively few connections have to be made at a greater height. Thereafter, the entire formwork panel unit can first be partially lowered by pivoting the cantilever arm 4 downward, namely by at least half of its extent parallel to the pivot axis 6 of the cantilever 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 control panels 2 is turned upwards. Then the formwork panel unit can be finally put down by further lowering the cantilever arm 4 and dismantled on the upward-facing rear side. A large part of the disassembly takes place in a safe position on the floor.
  • the formwork unit consisting of several formwork panels 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 cantilever arm 4 is pivotable by at least 180 ° relative to a horizontal position in order to be able to carry out the desired complete reversal.
  • the pivot axis 6 of the cantilever 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 cantilever arm 4.
  • a hoist is shown in which the holding head 5 is carried by an at least two-arm boom 4 a, the two bars 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 cantilever arm 4 or 4 a and the holding head 5, but these 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 embodiment according to FIG of the 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 cantilever arm 4.
  • a thread 11 adjustable in height on a shoulder 12 of the pivot bearing 13 at the free end 3 of the cantilever arm 4.
  • the pivotable cantilever arm 4 or 4 a is mounted on a frame 14 which is respectively movable in the exemplary embodiment, this movable frame 14 having steerable wheels 15, preferably provided with caster.
  • this movable frame 14 having steerable wheels 15, preferably provided with caster.
  • the shuttering of ceilings can be facilitated under certain circumstances by mounting larger panel units on the floor and then using the device 1 to detect them, turn them over and bring them into position.
  • the device 1 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 protection, a turning device 16 shown in FIGS. 4 to 6, which is arranged in the region of the swing-out arm 4 a and supports or Has receiving openings 17 for pivot pins 18 attachable to the panel units 2.
  • a turning device 16 shown in FIGS. 4 to 6, which is arranged in the region of the swing-out arm 4 a and supports or Has receiving openings 17 for pivot pins 18 attachable to the panel units 2.
  • One of the supports 17 and a pivot pin 18 are shown separately in FIG. 6.
  • This turning device 16 which is also part of the invention and on which formwork panel units 2 can also be placed with the aid of a device 1 according to FIGS. 1 and 2, is formed by a scaffold consisting of two independent parts, which has a chassis 19 with preferably steerable wheels 20 is provided.
  • a formwork panel unit 2 can also be transferred to another location and finally dismantled there or be used again.
  • the turning device 16 itself as well as the lifting device of the device 1 can be easily adapted to the different locations at which stripping or possibly stripping work must be carried out.
  • the device according to the invention includes the rail 21, clearly shown in FIG. 6, which can be attached to the panel edges of the panel unit 2 to be handled, with a bolt 18 projecting from the panel 2 parallel to the formlining, such rails 21 with bolts 18 each at two opposite edges are to be attached, 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 panel unit can then be turned.
  • the pivot pins 18 which can be attached to the formwork panels 2 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 becomes clear on the basis of FIG. 6 in connection with FIG. 4, where the arrangement of a suspended formwork panel unit 2 is indicated in the upper area in dashed lines.
  • the pivot pins 18 can have on their head 21 a and / or on their area 22 facing away from the head a cone directed towards the support 17, which causes an automatic centering between the pin 18 and the turning device 16 when inserted.
  • the two turning devices 16, which together receive a formwork panel unit are mobile, because they can follow the forces exerted by the cone and gravity well.
  • the supports or receiving openings 17 of the turning devices 16 are height-adjustable and preferably adjustable and fixable by means of working cylinders 23.
  • the supports 17 for the pivot bolts 18 of the turning devices 16 are guided such that they can be adjusted in height in a turning frame 24 and that 17 tension elements 25, in particular chains, act on these supports Lead via an upper deflection wheel 28 to the movable part, namely the piston rod 27 of the working cylinder 23. If this working cylinder is now actuated, the stroke movement is practically doubled compared to its stroke, and the supports 17 can also be lowered to the floor below the highest position of the piston rod.
  • the 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 entire device is independent of any power connections.
  • the turning devices 16 in the exemplary embodiment consist of two scaffolds which can be set up in mirror symmetry and can be moved independently of one another, the facing feet 29 or the like. Bearings with the wheels 20 which fit under the cantilever arm 4 or 4 a of the hoist 1. These feet 29 are lower than z. B. a squared timber or the like. So that 29 squared lumber can be placed parallel to these support feet, on which the formwork unit 2 detected by these turning devices 16 can be finally deposited after turning. The turning devices 16 can then be pulled out on both sides and moved away and used for further use.
  • 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.
