DEVICE FOR INSTALLING LIGHT ELEMENTS

FIELD OF THE INVENTION The present invention relates to a lifting device for installing lightweight elements in a mounting location, such as a building wall, ceiling or the like, comprising a lightweight intermediate storage compartment associated with a lifting device, a lift for.

10 As the construction industry is now highly industrialized, many different elements are used in construction. The elements can range from heavy load-bearing elements to lightweight wall surface elements or dielectric elements. Lifting and moving heavy elements generally requires that the element have, for example, lifting loops from which they can be hung on the crane 15 hook. Instead, lightweight elements can be lifted, for example, by gripping the plane surface of the element with suction cups. Alternatively, the lightweight element may also be raised by gripping a tongue or other similar groove formed at the edge of the lightweight element.

Light elements commonly used in buildings include wall elements with insulating wool in the center 20 and thin metal plates on both sides. The surface of the element is so smooth that it can easily be grasped by the suction cup lift. However, lightweight elements made of insulating wool and metal plates can also be lifted with a tongue and groove crane. This is because the metal plate on the surface of the element is turned over the edge of the element so that. . it forms a groove on the edge of the lightweight element. When lifting the element, the gripping element • 25 is guided to the tongue where it is caught.

. 'The suction cup hoist can also be used to mount other flat elements used in buildings, such as window elements, window glasses, stone surface elements, etc.'. · In view of the above, it can be said that almost all those used in buildings; '': 30 elements may be considered lightweight regardless of the way they are lifted, possibly with the exception of solid concrete load-bearing wall elements.

According to the known installation method, lightweight elements '!' For wall or ceiling mounting lifted individually to the wall or ceiling. However, the installation work will be substantially enhanced when a ':' ': interim storage of the applicant's prior invention is provided in connection with the hoist. This solution is disclosed in International Publication No. WO 95/25210.

According to the publication, the elements will be mounted more effectively on walls, ceilings or other installation sites 2 108636 because the lift will take a new element in the vicinity of the installation from the intermediate storage in the lift. Previously, the lift had to fetch each element further from the ground or from the actual warehouse.

It is an object of the present invention to provide a lifting device which further enhances the installation of lightweight elements. The problem with known lifting devices is that even if the elements are received at the installation site, the attachment of the elements is still difficult.

The device according to the invention is characterized in that the workstations are connected to the lifting device by means of spacers such as joints, projections or the like, so that the workstations are independently movable vertically and / or horizontally to achieve the desired workstation and height for each installer.

15

The workstation may be a platform or, for example, a platform. The installer workstation is primarily movable near the installation site for the lightweight panel. However, it can be so mobile that it moves the person to the intermediate storage unit as needed, or even lifts the person from the ground to the desired location. By means of the mounting device 20 according to the invention, the installation of the element is substantially enhanced. After all, it is possible to move one or more installers to the required installation site (s) at all times. Another advantage of the invention is that no separate lifting device is required in addition to the lightweight element. Often, site conditions are so cramped that. . there are several separate lifts that cannot fit there.

According to the embodiment shown in Figure 1, the workstations are personal lifting baskets 26a and 26b located at the ends of booms 25a and 25b attached to the frame 24 of the lifting device 20. Hydraulic cylinders 27a and 27b are connected to booms 25a and 25b, which allow the positioning of the lifting baskets 26a and 26b to be changed both horizontally and vertically. Thus, the personnel lifting baskets 26 can be moved almost anywhere to which only booms 25a and 25b reach. The baskets 26 can be moved in the vicinity of the lightweight element 21c to be installed, but they can also be lowered or raised so that the person installing the elements can rise from the ground to the baskets 26 and move to the desired mounting position.

Fig. 2 shows the lifting device 20 in a situation where the lifting unit 22, by means of suction cups 23, engages the upper lightweight element 21 in the intermediate storage of the lifting device 20. The work platform hoists 26a and 26b are located on the sides of the lifting device. The figure shows that the vertical columns 28a and 28b of the wall structure 15 are adjacent to the lifting baskets 26a and 26b, whereby both ends of the lightweight element 21c can be easily attached to the vertical columns 28a and 28b, for example by screws.

Fig. 3 shows a situation similar to Fig. 2, in which the lifting device 20 is in the vicinity of the inner corner of the building 20. The figure shows that the elevator car 26a can then be moved closer to the frame 24 of the lifting device 20, thus reaching the lifting device 20 to the very corner of the building. If the lifting basket 26 is suspended by the boom 25 shown in Fig. 1, the lifting basket can be easily moved laterally either at an angle to the pillar 28a,. near or away.

25 '. Fig. 4 illustrates a situation in which the work platform 26a of the second work station is displaced by a boom v '25a in the vicinity of the lightweight element 21c to be installed temporarily. This situation corresponds to the situation of Fig. 3 where the lifting device 20 must

Figure 7 illustrates another embodiment of the invention in which the frame 24 of the lifting device 20 is fitted with only one boom 25 and has only one workstation at its end. Such a structure is advantageous when the lightweight elements 21 are mounted vertically in a space where the elements do not need to be superimposed. In this case, the installer in the lifting platform 26 10 secures the upper ends of the light elements 21c and the second installer in the ground 29 secures the lower ends of the light elements 21c.

Fig. 8 illustrates a third embodiment of the invention in which a lifting device 20 is provided with stairs 30 through which the installer can ascend to a platform 31 and 15 connected to the boom 25 and then move to the workstation 26.

In Figure 9, the lifting device 20 is suspended at the end of a boom crane or similar boom. The figure does not show the boom crane itself but its attachment unit 32. This solution also allows the lifting device 20 to be easily moved to high positions 20 which do not reach the ground.

Fig. 10 shows an embodiment in which a boom 33 having no wheels supported on the ground is connected to the boom 33 of the boom crane. In the figure, the lifting basket 26a of the first work station is connected to the lifting device 20 in the manner shown in Fig. 1, * · '· 25 to the upper part of the frame 24. The second work platform lift platform 26b, on the other hand, is connected to: 'the lower part of the frame 24 of the lifting device 20 so that the lower ends of the light elements to be mounted vertically can be fixed by this lifting platform 26b.

Fig. 11 shows a lifting device 20 according to the invention positioned on a wheeled: * i ': 30 scissor lift 34. Also connected to the lifting device 20 is a workstation according to the invention, i.e. a personal lifting basket 26. The figure shows that the installer 35 is exactly. In the embodiment shown in Fig. 11, the lifting device 20 is provided with a lifting unit 22 having a tongue lifting means 36 for lifting the lightweight element 21 from the tongue. Therefore, the lightweight elements 21 in the intermediate storage 37 of the lifting device 20 are: '' · Side by side in upright position. 1 I I »β 108636

Figure 12 shows the lifting device 20 of Figure 11 positioned in the fork of the forklift truck 38. In other respects, the lifting device 20 with the work platform lifting platform 26 corresponds to the lifting device 20 shown in Figure 11.

In the embodiment of Figure 13, the lifting device 20 is disposed in the fork of a forklift truck 38, where the lifting device 20 can be raised to a desired height. The work platform hoist 26 for the installer 35 also moves to a suitable mounting height. Also in this lifting device 20, the lifting unit 22 is provided with a clamping member 36 for lifting the light element 21 instead of a lightweight element 10 21 located in the intermediate storage 37 of the lifting device 20. engaging the uppermost light element 31 in the intermediate storage 37, presses the light element against the upright body 24 of the lifting device 20. The advantage of this arrangement is that, when the gripping member 36 engages the tongue of the lightweight element 21, the lightweight element 21 cannot slip and thus remain in place to facilitate tongue gripping.

Figure 14 shows a lifting device 20 having wheels for moving on the ground. The machine's hydraulic system is driven by an electric motor that is powered by cable 39. In this embodiment, the workstation for the installer 20 35 is a platform 26 mounted on the hydraulic cylinder 40, which can be raised to the desired height by the hydraulic cylinder.

Fig. 18 shows a lifting device 20 suspended, for example, on a crane boom by means of a fastening unit 32. This mounting unit 32 is locked during installation so that the lifting device 20 cannot move relative to the top of the crane boom. This ensures that the lifting device 20 is securely held in place when the lightweight element 21c is attached to the vertical column 28 of the building frame. However, the fitting 32 15 can be released so that the lifting device 20 can pivot through the joint 42. In this case, the lifting device 20 may be allowed to tilt, for example, when the crane boom makes a large movement when raising the lifting device 20 from the ground up to the mounting height. However, for the mounting situation, the joint 42 is again locked in motion.

Fig. 22 shows a machine feeder 47 connected to a workstation personal lifting basket 26 of the work platform according to the invention. In the embodiment shown, the feeder 47 is formed by a cylinder 48 whose piston 49 is movable, for example, by foot pedal 50. The structure may be implemented mechanically, pneumatically or hydraulically. In Figure 22, the hose between foot pedal 50 and cylinder 48 is designated by reference numeral 51. Essentially, the installer 35 does not need to support the work machine, which in Figure 22 is a drilling machine 52. However, the work machine 52 can equally well be a screwdriver, for example. In the figure, the installer 35 can move the drill machine 52 supported by the eccentric arm 53 to the desired position and then depress the foot pedal 50, whereby the feed motion of the piston 49 also provides the feed motion of the drill machine 52.

Fig. 23 is a horizontal view of the machine feeder 47 connected to the work platform hoist basket 26 of Fig. 2. The cylinder 48 of the feeder 47 is secured to the lifting basket 26 by means of a joint 54 20, whereby the cylinder 48 is pivotable from the vertical position shown in Figure 22 to the horizontal position of Figure 23. When the cylinder 48 is in the horizontal position, the foot pedal 50 provides a horizontal feed movement of the piston 49 and also the drill 52. The eccentric arm 53 allows the drill machine 52 to be moved to the desired position before. . actual drilling feed. It is clear that fitter 35's work will be faster and lighter '· 25 when he does not have to support a heavy duty drill 52 or I 1 ·. 'Screwdriver in his hands. 2 2 1 t • ', · Fig. 24 shows the lifting device 20 and the installation situation in which it has been performed; the first step of installing the lightweight element 21c. By means of the boom 57 of the lifting unit 22, the vertical lightweight element 21c supported by the suction cups 23 is positioned against the vertical pillars 28a and 28b of the building wall. The lifting unit 22 also includes, 1 1 ·, a joint 59, by means of which the light element 21c can be brought parallel to the wall plane. In addition, the lifting unit 22 includes a longitudinally movable slide 60 of the lightweight element 21c, by means of which the element is positioned at the point of installation in this direction.

Fig. 24 shows that there is a gap 55 between the previous fastened light element 21b and the light element 21c to be installed. This is because the tongues 56a and 56b of the light elements 21b and 21c require a final mounting movement in the direction of the element plane, as shown. It is only after this that the tongues 56a and 56b of the lightweight elements 21b and 21c are tightly seated against each other, thereby locking the joint between the elements 21b and 21c.

Figure 25 illustrates the attachment of the lightweight element 21c after the second step of installing the lightweight element 21c, i.e., a lateral mounting movement parallel to the plane of the lightweight element. The lateral movement is achieved by means of a slide 58 between the boom 57 and the frame of the lifting device 20. The slide 58 moves the boom 57 always 10 horizontally, but the slide 60 at the opposite end of the boom always moves the light element along its length. As shown in the previous Figure 24, this adjusting movement of the lightweight element 21c in the vertical direction is also in the vertical direction.

When, in Fig. 25, the light element 21c is displaced laterally by means of the lifting boom 15 57 and its slide 58, the joint between the tongues 56a and 56b is tight. Thereafter, the installer 35a in the work platform lifting platform 26a drills a hole 52 in the drill machine at the end of the light element 21c, after which the installer screws a screw that locks the end of the light element 21c into the vertical column 28a of the building wall. Similarly, the installer in the second lifting platform 26b attaches the opposite end 20 of the lightweight element 21c to the vertical column 28b. The lifting device 20 then takes the next light element from its intermediate storage and moves to where it is intended to be mounted. Of course, self-drilling screws can also be used, requiring only a screwdriver for installation. The drill can also be used as a screwdriver. 1 to 25 It will be apparent to one skilled in the art that various embodiments of the invention may vary within the scope of the following claims.
