DEVICE AND METHOD FOR ARRANGING BUILDING PANELS

Abstract: Method and device for creating building plates in a building consisting of a tiltable support table with an under­ frame having wheels.

Description: The invention relates to a method for arranging building panels in a building frame, whereby a series of building panels lying adjacently on their long edges is set up in a compartment of a building frame, whereby said panels rest with their ends on at least two supports placed at a distance from each other and whereby each time one building panel is removed from said series and is set up in its place in said building frame with its both long edges upright, whereby a supporting table of a device for arranging building panels is tilted about two axes transverse to each other relatively to a rolling sub-frame bearing said supporting table. Such a method is disclosed in DE-A-3434367. With said known method the mentioned device is used in combination with a car picking up the building panels in upright position and bringing them to a remote place in the building structure. Said known device may be useful in great buildings with large floors, but is not useful on small floors. Building panels in a building frame with small floors are completely manually brought from the series up to their place in the building frame. In this method the movements of the building panels are also manually tilted. Setting up building panels is heavy work, which, for building panels of lightweight concrete with measurements in the order of magnitude of 10 x 60 x 270 cm at a weight of for example 130 kg, must be carried out by two people. Even then it is a heavy and difficult job that results in many back complaints. The present invention has for its object to facilitate the work of erecting building panels with the use of a simple device, particularly useful on small floors. To this end the method of claim 1 is proposed. It is noted that US-A-3335883 discloses a device for lifting and moving elongated items, such as beams, pipes etc., said device comprising a supporting table which can tilt on at least two axes transverse to each other and a sub-frame bearing said supporting table, said sub-frame having a substantially centrally located wheel shaft, said supporting table being able to pivot substantially about said central wheel shaft, said supporting table being attached for pivoting to said sub-frame on a swivel axle located between the two wheels of said central wheel shaft and extending transversely to said shaft and said pivot table having supports between said swivel axle and a table panel of said supporting table, which supports leave free a space for receiving a wheelpart and said supporting table in the standing receiving position pivoted on said swivel axle receiving the wheel in said receiving space between said swivel axle and said table panel. This device has a lever which is rigidly connected to the supporting table and which protrudes beyond the side thereof. In the method according to the invention however, the lever is brought in lever-engagement with the supporting table before the swinging movement and is taken out of engagement afterwards so that the device has a small size which is advantageous when operating on small floors. Features and preferred embodiments of the invented method are designated in the subclaims and explained in the description following hereafter with reference to a drawing. In the drawing in diagram form: Fig.1 shows an exploded perspective view of a preferred embodiment of a disassembled device used with the method according to the invention, with the auxiliary tools to be preferably used, Figs. 2 and 3 show a partially broken away, perspective view of the device from Fig. 1 in assembled state in the two outermost tilted positions of the supporting table relative to the sub-frame, Fig. 4 is a side view of the device from Fig. 3, Figs. 5-10 show perspective views of successive steps in the performance of the method according to the invention with the device of Fig. 2, and Fig. 11 is a front view of another device for performing the method according to the invention. The device 1 with the method according to the invention that is shown in Fig. 2, is assembled from a sub-frame 2 and a supporting table 3 which are disconnectably attached together by means of a pivot rod 4. The sub-frame 2 consists of a non-rotating shaft 5 which has at both ends a freely rotatable wheel 6 mounted with bearings and having a pneumatic tyre 7. Close to the one wheel 6 there is welded on the shaft 5 and directed at right angles to it a pivot bar 8 which has two pivot ears 19, one on either side of the shaft 5. Close to the other wheel 6 a support 10 is present to which is fastened the end of a chain 11. The supporting table 3 is built up of two longitudinal girders 13 and 18 having three transversely directed corner profiles 14 to the top side of which are attached protruding wooden beams 15 on which a building panel 9 can rest while running little risk of being damaged. A rectangular small frame 16 having longitudinal girders 27 and 28 is rigidly connected to longitudinal girders 13 and corner profiles 14 with supports 17 directed inclining upwards. At the longitudinal girder 27, that is, close to the ears 19, the frame 16 has pivot holes 20, with the result that the pivot rod 4 provided with a handle can be placed through these pivot holes 20 and ears 19, whereby the parts 2 and 3, which are in themselves light and can be carried separately from each other by hand, can be easily combined into a device 1 according to the invention. During assembly the free end of chain 11 is hooked onto a hook 24 which is attached to the longitudinal girder 28, which can be seen in the drawing. The longitudinal girder 27 has an upright, U-shaped gripper member 30 welded to it. During performance of the method according to the invention building panels 9, as a series 33 of building panels 9 which are positioned against each other with their long side 34 on two wooden supports 35 located at a good distance from each other (fig. 6), are placed in a building frame 36. These building panels 9 have then to be arranged on end (see fig. 10). The method according to the invention can be carried out easily and quickly by one person using the device 1. To this end the supporting table 3 is first tilted relative to sub-frame 2 from the position in fig. 2 into the slightly inclining, downward position of fig. 3. The chain 11 determines the maximum tilt position. Teeth 37 attached to the lower longitudinal girder 13 thereby protrude sideways outside the supporting surface 38. The teeth 37 are situated symmetrically on either side of shaft 5 at a substantial interval a from each other. The teeth 37 are located at a low level beneath the long side 34 of the foremost building panel 9 when the device 1, being manoeuvred at a slight slant, is moved against this building panel 9. When this device 1 arrives it will possibly come up against this building panel 9 with an end of the supporting table 3, while the other end of supporting table 3 is located a short way from it. The building panel 9 is then pulled a little towards the device 1 at this point with the hook 40 as according to arrow 41 with the result that it comes parallel to the lower edge of supporting table 3. As according to fig. 6 a separate lever 42, for example steel pipe, is then inserted into the gripper member 30, the hook 40 is hooked around a support 17 close to the upper longitudinal girder 13 and the supporting table 3 is tipped over together with the building panel 9 as according to arrow 44 on pivot rod 4 by means of lever 42. By making a good choice of the arrangement of pivot rod 4, that is, at a height of for example 30 to 40 cm from the ground, little force is necessary when tipping over. The last part of the tipping movement is slightly decelerated with the same lever 42. When this tipping movement is carried out the hook 40 can if necessary be first pulled slightly to help start the tipping movement and if required the movement is cushioned somewhat at the end with the hook The lever 42 is removed (see fig. 7). A piece of the building panel 9 is then if necessary sawn off, whereby an end 46 is then laid on a table 47. The device 1 then also serves as sawing table. The building panel 9 is then moved with device 1 to the set-up location 48, whereby the lower side 49 of building panel 9 is set down near the set-up location 48, whereby the supporting table is tilted on the shaft 5. As in fig. 9 the building panel 9 is then lifted from the device 1, whereby building panel 9 is tilted on its lower edge 49 so as to be pointed upright as according to arrow 50. The person 51 hereby walks around the device, whereby the building panel 9 is also turned on the corner 52 in arrow direction 53, so that the corner 54 comes approximately up against the already arranged adjacent building panel 9. The building panel 9 to be handled is if necessary moved a little with swivel steps, which is not a heavy operation. When the building panel 9 is standing in position it is raised slightly with a kind of crow-bar 56 with the result that its upper edge 57 comes to rest in a U-profile 59 attached against the ceiling 58 of the frame 36. In this raised position wedges 60 are driven beneath the edge 49 whereby the setting-up of this building panel 9 is completed. The device 61 of fig. 11 corresponds with device 1, with the understanding that the sub-frame 62 of the former has a bush 63 which can slide on the shaft 5, to which bush the pivot bar 8 is welded. As a result the downward tilted supporting table 3 can be placed against the foremost building panel 9 somewhat more easily, so that the first operation of placing the supporting table 3 parallel to the building panel 9 is superfluous. There are several conceivable variants of the device 1. The sub-frame 2, instead of having one wheel axle with two wheels, can thus have for example three or four wheels, at least one of which is a swivelling wheel. In order to then still be able to swivel the supporting table 3 on a shaft which stands perpendicular to the tilting pivot rod 4, the third and possibly the fourth wheel can be raised during tilting on the fulcra of the other two wheels. Also conceivable is that for example one of the both ends of supporting table 3 has a fixed support which functions as the legs of a wheelbarrow for setting down the supporting table during sawing without a table 47 being necessary.
