Definitions
- the present invention relates to a device according to the preamble of claim 1.
- Ceiling panels are usually lifted for mounting under the ceiling and held in this position. In this position, the ceiling panels must then be attached to the ceiling. However, this requires precise alignment and positioning. The adjacent ceiling tiles must sit against each other with a predetermined gap. Only then can the assembly be carried out. At least two people are required to lift the ceiling panels into the fastening position. The movements of the people must then be coordinated in such a way that the adjacent ceiling tiles adjoin each other with a predetermined gap.
- a mechanical lifting device is known from US Pat. No. 3,910,421, with which the ceiling plate can only be brought into its approximate end position.
- the ceiling-side transverse edge of a ceiling panel to be mounted is squeezed when swung up.
- the lift frame can therefore only be used sensibly in the wall area because there is no need to pinch it under the ceiling.
- the ceiling panel to be assembled is lifted like a millimeter under the ceiling, where it can still be aligned and positioned in the raised position before it is finally held in the fastening position so that it is with the underside of the ceiling can be firmly connected.
- the invention keeps the ceiling plate which has not yet been installed practically in its final mounting position.
- the second clamp support works in cooperation with the parallel supports of the first clamp support.
- the plate lift in the mounting position of the plate support can be moved so high in the vertical direction that the ceiling plate lies directly under the ceiling over its entire length that the vertical movement of the plate lift is hindered by touching the ceiling.
- the pre-clamp support is supported under the ceiling.
- the top of the board can be moved down to the thickness of the board under the underside of the ceiling.
- the invention provides that the lift frame is formed by two clamp supports, both of which are clamped between the floor and ceiling.
- the lift frame including the plate lift can consist of individual removable elements that are also transportable if necessary.
- the length of the pinch support is somewhat greater than the clear distance between the floor and the ceiling. Then both pinch supports can simply be under axial Compressive stress between the floor and ceiling.
- the pre-clamp support can also be moved apart to achieve the clamping. Ensure that the plate support can move freely into the fastening position.
- the plate lift is designed in such a way that it offers a pivotable plate support which is connected at one end to the pre-clamping support via a rotation axis that is practically parallel to the ceiling.
- the axis of rotation parallel to the ceiling is offset at least by the plate thickness from the underside of the ceiling, while the top of the plate support should then have the distance of the plate thickness from the underside of the ceiling.
- the respective swivel position of the plate support corresponds to the sloping roof angle, after which the ceiling plate to be installed then reaches its fastening position flush and parallel to the sloping roof.
- the top of the plate support can be pivoted practically flush with the underside of the fully assembled ceiling panels under the ceiling.
- the pivotal movement of the plate support is generated via a practically parallel axis of rotation on the pre-clamping support, via which the plate support is connected to the pre-clamping support.
- This clamp support is referred to as the pre-clamp support because it is clamped under the ceiling on the plate support in the laying position before placing the ceiling plate and provides a first fixed bearing for the lift frame with plate lift.
- the plate support In this lowered position, the plate support is fitted with the ceiling plate to be installed and then swiveled under the ceiling around the axis of rotation parallel to the ceiling on the pre-clamping support.
- another clamp support is moved under the swung-up plate support and clamped under it so that the swiveled-up plate support is held in this position by clamping.
- the swivel angle - related to the vertical - can be ⁇ 90 ° and slightly above.
- a ball joint is preferred so that the post-clamping support can move freely in all directions.
- a height adjustment of the clamp supports is proposed.
- the height can be adjusted continuously or discreetly.
- a fine height adjustment can also be provided. Exemplary embodiments are given for this.
- a lift frame with only two clamp supports can therefore be considered for the invention.
- a lift frame should be included, which is designed as a so-called tripod and can therefore stand independently in each room.
- a high degree of lateral stability is also achieved when several support points are connected by a common bridge, on which only one clamp support is located centrally.
- the reaching bridge should be positioned directly below the ceiling, so that lateral tilting is prevented.
- the panel support can be positioned exactly.
- the plate support can be adjustable in length and / or adjustable in width.
- Another important aspect is based on the fact that when the pre-clamping support is clamped in with the plate support pivoted down, that is to say when the plate support is to be fitted with the ceiling plate, there is a risk that the ceiling plate placed on it will slide down.
- the favorable lever ratios in the case of a swiveling plate support can be additionally improved if the swiveling movement of the plate support takes place via a swivel gear.
- the slewing gear is to be supported with a support strut on the one hand on the plate support and on the other hand on the pre-clamping support. Exemplary embodiments are given for this. The invention is explained in more detail below on the basis of exemplary embodiments. Show it
- Fig. 1 a first embodiment of the invention
- Fig. 2 an embodiment of the invention with height-adjustable clamp supports
- Fig. 3 a perspective view of the invention with various embodiments
- Fig. 4 a sketchy illustration of the invention with a continuously variable lifting gear
- Fig.5 an embodiment of the invention with discretely lockable lifting gear
- the figures show a device for the assembly of ceiling panels 8.
- Such ceiling panels 8 usually have dimensions that require processing by at least two employees.
- Such ceiling panels 8 are lifted under the ceiling 3 and in the raised position e.g. nailed, screwed or the like to a ceiling battens 10.
- the exemplary embodiments shown show that a lift frame 1 is provided for this purpose, which is formed from clamp supports 11a, 11b, which can be clamped between the floor 2 and the ceiling 3 under an inclined position.
- the length of the clamp supports 11a, 11b is slightly larger than the clear height of the room in which the ceiling panels are to be mounted. Therefore, the clamp supports 11a, 11b are not exactly vertical but at an angle of approximately up to 5 ° to the vertical.
- the clamp supports 11a, 11b are wedged under the ceiling 3 in the fastening position 7 shown and are immovably fixed.
- a pivotable plate support is provided here as the plate lift 4, which is connected to the one clamp support 11a at a ceiling-side end 13 via a rotation axis that is practically parallel to the ceiling.
- the clamp support 11a is referred to as a so-called pre-clamp support. This will be discussed later.
- the axis of rotation 48 extends in such a way that the top 14 of the plate support 4 can be pivoted practically flush with the bottom 15 of the fully assembled ceiling panels under the ceiling 3.
- a further clamping support 11b can be clamped under the pivoted-up plate support 4 at the opposite end 16 of the plate support.
- the original bottom end of the plate support 4 is wedged under the ceiling and held there by the clamping support 11b, which acts there and is referred to as the post-support, after it has been swung up into the fastening position 7.
- the process of lifting the ceiling panel 3 to be assembled is therefore two-stage.
- the entire assembly device with the post-clamping support 11b pivoted away must be brought into the laying position 6.
- the pre-clamping support 11a is wedged under the ceiling.
- the plate support 4 has the distance of the plate thickness from the underside of the ceiling, while in addition the corner-parallel axis of rotation 48 the plate support 4 is offset at least by the distance of the plate thickness from the underside of the ceiling. This distance will practically have to be increased by the distance which arises between the top of the plate support 4 and the axis of rotation 48 parallel to the ceiling.
- a clamp-parallel support 50 is used to clamp the pre-clamp support 11a under the ceiling, which is arranged at the upper end of the pre-clamp support 11a so as to be pivotable about a further axis of rotation 52 provided there parallel to the ceiling.
- the ceiling-parallel support 50 has, on its edge facing the plate support 4, an upright stop flange 51, the height of which corresponds to the plate thickness above the support 50 or falls below this by 1-2 mm.
- a fixing tip 55 can also be provided, which digs into the ceiling / fastening battens from below. The fixing tip 55 projects above the already installed ceiling plate 8 by a few mm.
- the height 53 of the stop flange 51 is not greater than the thickness 54 of an already installed ceiling panel, but falls below it as little as possible. This will pinch the Pre-clamp support 11a under a previously assembled one
- the material thickness of the stop flange 51 thus determines the width of the expansion joint that is to be left free between adjacent ceiling panels in order to enable thermal expansion.
- the pre-clamping support 11a determines the exact joint width of two adjacent ceiling panels as soon as it is wedged under the ceiling.
- the post-clamping support 11b is pivotally connected to the plate support 4 in such a way that it can be pivoted about the ball joint or about the pivot axis 17 at an acute angle 18 to the plate support 4 when it is in the resting position 6.
- the principle of the invention thus also consists in that with the plate support 4 fitted, when the plate supports move in the direction of movement 5, the top of the ceiling plate 8 is lifted over its entire length up to just below the fastening brackets 10 until its top there and with its underside is flush with the neighboring already installed ceiling panel.
- the pivoting mobility of the post-clamping support 11b is made possible by the pivot axis 17.
- the pivot axis 17 sits on the bottom end 16 of the plate support 4 when it is in the resting position 6.
- a swivel movement of up to 180 ° in all directions can be made possible by a ball joint.
- devices 19 for height adjustment are provided. These devices are divided into devices for stepless height adjustment 20 or for stepwise height adjustment 21.
- the pre-clamping support and / or the post-clamping support 11a or 11b is provided with a thread 23, which can be adjusted to the required length dimension in connection with the thread engagement of a threaded counterpart 24 on the ceiling.
- the thread 23 is an external thread, which is attached to a foot piece 22 of the pre-clamping support or the post-clamping support.
- the pre-clamping support 11a and / or the post-clamping support 11b is divided into an upper part 25 and a lower part 26, and the upper part 25 and lower part 26 can be displaced in the longitudinal direction relative to one another and are fixed in the displaced positions.
- the height can be adjusted in predetermined height steps 21 in that the upper part or lower part are constructed from tubes which are inserted into one another.
- the inner tube has transverse bores 27 which are arranged at predetermined intervals from one another.
- the outer tube is provided with at least one transverse bore, which is referred to as the positioning bore 28.
- the positioning bore 28 can be brought into alignment with the transverse bore 27. In the aligned position, the plug pin 29 should then be inserted into the positioning bore 28 together with the transverse bore 27 aligned therewith.
- the plate support 4 can have at least three support points 30, 31, 32, which together span a tripod. In this way, there is also an independently standing lift frame to which the plate support 4 is articulated. In addition, provision can be made to connect two of the support points 30, 31, 32 by a bridge 33, to which only a clamp support is then to be attached.
- the plate support 4 In order to adapt the plate support 4 to the respective plate dimension, it should be formed by at least two parallel support struts 34, 35 which run practically parallel between the pre-clamp support 11a and the post-clamp support 11b and are adjustable at least to the length of a ceiling plate 8.
- a length adjustment and fixing device 36 which consists, for example, of a hollow profile strut and an inner strut which is slidable and fixable relative thereto.
- a plate system 37 is provided on the side of the reclamping support 11b on the plate support 4, which protrudes over the top of the plate support 4 and there provides a contact edge for the ceiling plate.
- the plate system 37 should have an overhang dimension 38 which is 1-2 mm less than the plate thickness dimension 39. In this way it is achieved that when the plate support 4 is swung up in the fastening position, the upper edge of the plate system 37 ends unobstructed in front of the underside of the ceiling. Nevertheless, the ceiling plate is located directly under the mounting brackets 10 and can preferably be attached.
- the plate system 37 makes it possible, on the one hand, to set the exact length of the plate support 4 in accordance with the length of the ceiling plate 8 to be installed.
- the plate system 37 offers a defined contact edge for the ceiling plate 8 to be assembled.
- the length of the plate support 4 is then to be set so that the axis of rotation 48, about which the plate support 4 can rotate, lies in the rear plate plane 49 of the ceiling plate 8.
- the further function of the plate system 37 is that, with the correct length adjustment of the plate support 4, each placed ceiling plate 8 can be pivoted in a defined position under the ceiling 3.
- a swivel gear 40 can be provided, which can be fixed in the fastening position 7.
- at least one support strut 41 can be provided on the swivel gear 40, which is articulated on the plate support 4 and which is adjustable with a swivel drive and can be fixed on the pre-clamping support 11a.
- the support strut 41 can be provided with latching recesses 43 which can be hooked into latching projections 42 as an abutment.
- the support strut is used in the hooked position as a rigid connection between plate support 4 and pre-clamping support 11a.
- a continuously variable lifting gear can also be provided for the exact positioning of the plate support 4 under the ceiling 3.
- the lifting gear comprises a toothed drive 44 which, in conjunction with a toothed locking strut 45, enables the vertical movement of the plate support 4.
- the upper side 14 of the plate support 4 when the plate support is swung up, lies in one plane with the underside 46 of the ceiling, so that the ceiling plate 8 to be assembled is in flush contact with the underside 46 of the ceiling.
- the relevant underside of the ceiling 46 coincides with the surface enveloped by the lower fastening surfaces of the battens 10.
- the foot pieces 47 can be made of a soft, elastic material that does not slip on the usual floor materials even when tilted under load.
- the pre-clamping support 11a must be wedged under the ceiling so that the support 50 parallel to the ceiling is practically fixed at a distance from the panel thickness below the ceiling.
- a spacer plate or the like which can be produced from the plate material, should alternatively be clamped between the parallel support 50 and the underside of the ceiling.
- the upright stop flange 51 is positioned so that the basic alignment of the first ceiling panel to be installed is ensured.
- the upright stop flange 51 thus practically specifies the wall-parallel alignment of the ceiling panels.
- a ceiling panel 8 to be assembled is placed on the panel support 4 and this then up to the flush contact swung under the covers.
- the ceiling panel 8 to be assembled is then held under the ceiling without play. For example, it can be screwed onto an existing mounting bracket 10.
- the assembly device can then be moved into the next position.
- the upright stop flange 51 is now placed on the end edge of the ceiling plate 8 which has just been installed and the pre-clamping support 11a is then wedged under the ceiling.
- the material thickness of the stop flange 51 therefore defines the joint spacing between two adjacent ceiling panels so that a gap of defined width is created (e.g. 2 mm), which can then be filled.
- the height 53 of the stop flange 51 does not exceed the plate thickness 54 of already installed ceiling panels 8 but preferably falls below by 1-2 mm in order to place the ceiling-parallel support 50 exactly parallel on the underside of already installed ceiling panels 8 to be able to.
- the parallel point is not prevented by the centering tip, but the upper end of the pre-clamp support is practically already fixed when the pre-clamp support is not yet clamped.
