    ref. P 2020 NL 018 Title: Method and device for dismantling roofing sheets
    FIELD OF THE INVENTION The invention relates to the dismantling of external roof sheets from pitched roofs. More in particular, these are elongate roof panels which lie on horizontal girders (purlins), bridging the mutual distance between at least two adjacent purlins.
    BACKGROUND OF THE INVENTION Corrugated sheets can be used, for example, in the application of roof cladding to pitched roofs, and corrugated sheets containing asbestos have been widely used in the past. When these corrugated sheets have to be removed, this must be done carefully, with as little damage as possible to the sheets, in order to avoid the release of asbestos fibres.
    It has hitherto been customary for the corrugated sheets to be removed from the outside. The plates are loosened, and then lifted. A crane standing on the ground must be used for this. Detaching, lifting or attaching to the crane is done by human hands, as illustrated for example in DE-
    19618212. If people cannot or are not allowed to stand on the roof, they must be lifted above the roof in a work basket carried by a crane. The building in question is not always easily accessible for a nearby crane, so that a crane standing at a greater distance, and thus larger and more expensive, is required.
    SUMMARY OF THE INVENTION A Purpose! The aim of the invention is to provide an alternative whereby it is no longer necessary for workmen to stand outside on the sloping roof, and whereby it is no longer necessary to use lifting cranes.
    According to a first aspect of the present invention, the roof panels are removed from the underside, i.e. from the inside of the relevant building. The mounting bolts with which the roof panels are attached are cut or sawn at the bottom. Then the roof sheets are lying on a support, lifted from the purlins, moved further out, turned to a horizontal position, and then brought in between the purlins.
    According to a second aspect of the present invention there is provided a supporting lifting aid for performing the method,
    BRIEF DESCRIPTION OF THE DRAWINGS These and other aspects, features and advantages of the present invention will be further illustrated by the following description of one or more exemplary embodiments with reference to the drawings, in which like reference numerals designate like or similar parts, in which references "under/ above", "higher/lower", "left/right" etc exclusively relate to the orientation shown in the figures, and in which: figure 1 shows schematically a cross-section of a building with an oblique | roof clad with roofing sheets; figure 2 schematically shows a device according to the present invention; Figures 3-7 schematically illustrate the use of the inventive device.
    DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows schematically a cross-section of a building B with a pitched roof, which roof comprises horizontal purlins G, and roof sheets P mounted on said purlins.
    Figure 2 shows schematically a device 1 according to the present invention for removing said roof plates P from the inside. Here "from the inside" means that the device 1 is located in the building B under the roof plates P.
    The device 1 is intended for mounting on a working arm of a tractor or loader or similar working vehicle V, and for this purpose it comprises a quick-coupling adapter 70 for coupling to the end of said working arm.
    The device 1 further includes a lower frame 10 having a proximal end 11 proximal to the quick coupler adapter 70, and a distal end 12 remote from the quick coupler adapter 70. The direction from proximal end to distal end will be referred to as lateral direction; a horizontal direction perpendicular to the lateral direction will be referred to as transverse direction.
    The device 1 further comprises an upper frame 20 resting on the lower frame having a proximal end 21 and a distal end 22. The distal ends 12; 22 of the lower frame 10 and the upper frame 20 are pivotally coupled to each other by a hinge 30 having a pivot shaft 31 directed in said transverse direction.
    The device 1 comprises at least one controllable adjusting member 40 for adjusting a pivotal position of the upper frame 20 relative to the lower frame 10;
    in the embodiment shown, said controllable adjusting member 40 is designed as a hydraulic cylinder/piston combination.
    Mounted on top frame 20 is a controllable support conveyor 50 for supporting roof sheets P and for displacing said roof sheets in lateral direction relative to top frame 20 .
    Said support conveyor can for instance comprise a conveyor belt.
    In the embodiment shown, the support conveyor is a wheel conveyor, and comprises a set of wheels 51 arranged on the top of the upper frame 20, which are rotatable about rotation axes 52 directed in said transverse direction. The wheels 51 are preferably provided with pneumatic tires for carrying the to damage roof panels as little as possible.
    The support conveyor 50 comprises drive means 53 for synchronously driving the wheels 51 for rotation.
    In one embodiment, said drive means 53 may comprise a hydraulic motor, and the output motor shaft may be coupled to the respective wheels via V-belts.
    The number of wheels 51 is suitably equal to four, with two wheels mounted at the proximal end 21 and two at the distal end 22, always transversely spaced from each other.
    The respective wheel axles are aligned with each other.
    Also, the two proximal wheels can be mounted on a | common shaft, so as to always rotate equally, and the same applies to the distal wheels.
    If desired, more wheels can be present per axle, and if desired more wheel axles can be present.
    The quick coupler adapter 70 is pivotally coupled at its underside to the lower frame 10, pivotally relative to a transversely directed pivot shaft 71. A locking member 72, shown as a perforated locking strip, with matching locking pins 73 therein, fixes a selected pivot position of the quick coupler adapter. 70 relative to the lower frame 10. This effectively defines a pivotal position of the lower frame 10 relative to the tool arm, making it possible to adjust a working height. | With reference to Figs. 3-7, the use of the inventive device 1 will be explained.
    Figure 3 shows that the device 1 is lifted and placed under the roof plate P to be removed, wherein the top frame 20 is pivoted in such a way | with respect to the lower frame 10, which the orientation of the upper frame 20 conforms to the oblique orientation of the roof plate P and the wheels 51 touch the roof plate P (in the figure, the wheels 51 are shown remote from the roof plate P). Fastening elements (not shown for the sake of simplicity) which fasten the roof sheet P to the purlins G can now be removed, or have already been removed beforehand.
    Figure 4 shows that the device 1 is now moved slightly in vertical and/or horizontal direction in order to lift the roof plate P from the purlins G. This is possible because the stationary vehicle V moves its implement arm, and/or because the vehicle V a little forward.
    Figure 5 shows that the device 1 is then moved further outwards in the horizontal direction until an upper edge P1 of the roof plate P is positioned beyond the outer edge G1 of the upper of the two purlins G. This may be because the stationary vehicle is V. implement arm moves, and/or because the vehicle V moves slightly forward. It is also possible that the wheels 51 are driven to transport the roof plate 51 outwardly relative to the top frame 20.
    The upper frame 20 is pivoted downwards towards the lower frame 10, with the upper edge P1 of the roof sheet P passing the outermost edge G1 of the upper of the two purlins G and the roof sheet is given a smaller angle of inclination, such that the roof sheet is vertically between the fits two purlins. The roof plate P can come to lie exactly horizontal, but this is not necessary. The roof plate can even be pivoted horizontally to a position shown in figure 6 .
    Figure 6 shows that the device 1 with the roof plate P resting thereon is moved horizontally inwards into the building B. The working vehicle V can now lower its working arm, so that the device 1 is moved to the floor. In this case, the device as a whole can be held at an angle, and/or the top frame 20 can be tilted relative to the bottom frame 10, and the wheels 51 can be driven to gently lay the roof plate P down on the floor, as shown in figure 7 , or on a pile of previously removed roofing sheets.
    The device 1 is then immediately ready for the removal of a next roof plate. The device 1 will always be placed between two purlins under a roof plate in order to give this plate a horizontal orientation and to pull it in between the purlins. Due to the correct use of the working arm of the working vehicle, the device 1 will have a large working range in height.
    It will be clear to a person skilled in the art that the invention is not limited to the exemplary embodiments discussed above, but that various variants and modifications are possible within the scope of protection of the invention as defined in the appended claims.
    Even if certain features are stated in several dependent claims, the present invention also relates to an embodiment having these features in common.
    Even if certain features are described in combination with each other, the present invention also relates to an embodiment in which one or more of those features are omitted.
    Features not expressly described as being essential may also be omitted.
    Any reference numerals used in a claim are not to be construed as limiting the scope of that claim.
