2. Description of the Related Art In order to install the above-mentioned outer wall material on a building frame or the like to form an outer wall, the outer wall material is raised vertically from a horizontally placed state, and transported while maintaining that state. Here, in order to change the posture of the horizontally placed outer wall material and to stand it vertically, first suspend horizontally with a plurality of (2 to 4) wire ropes, and then use the fulcrum (normally the outer wall material) when vertically raised. End on the floor, etc., with a cushion of old tires in between, so that the fulcrum is not damaged.
Next, two wire ropes for vertical suspension are used to lift and raise the end opposite to the fulcrum.

[0003]

[Problems to be Solved by the Invention] As described above, in the work of changing the posture of the horizontally placed outer wall material to stand vertically, it is necessary to change the wire rope from a horizontal suspension to a vertical suspension, In addition, it is necessary that a cushion for preventing damage to the outer wall material is sandwiched between the fulcrum and the floor due to the outer wall material, and furthermore, when standing upright, the fulcrum portion does not come off the cushion and fall on the floor or the like. Since the operation is performed while the wire rope is moved laterally, it takes time, effort and time, and there is a complaint that the carrying operation cannot be performed at once. In addition, there is a risk that the wire rope may fall off the outer wall material and fall, and in the case of a heavy material such as concrete, a heavy burden is imposed on the worker.

[0004] The present invention has been made in view of the above circumstances, and when the outer wall material is lifted upright from a state where it is placed horizontally, the labor and labor for the worker is reduced, and the outer wall material is shortened. It is an object of the present invention to provide an external wall material lifting device that can be implemented in a timely and safe manner.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above-mentioned object, and an outer wall material is set up on at least the vicinity of the center of gravity of the outer wall material on the upper surface of the horizontally placed outer wall material. A beam that supports the outer wall material is detachably attached so as to extend along the direction in which the outer wall material stands over the upper end surface when the outer wall material is erected, and the beam can be moved along the beam length direction. A suspension bracket to be engaged and to which a hook of a lifting machine such as a crane is hung; and a suspension bracket driving device provided on the beam and moving the suspension bracket along the beam.
And the suspension bracket driving device is arranged along the beam.
And the spin screwed into the suspension bracket
And the spindle, rotate the
And a motor for moving the object along the beam .

[0006]

According to the external wall material lifting device of the present invention, the beam extends along the length direction of the external wall material from the center of gravity of the external wall material on the upper surface of the horizontally placed external wall material to the upper end surface when it is erected. At first, the hanging bracket is positioned on the center of gravity of the outer wall material, the outer wall material is lifted in a horizontal state via this hanging bracket, and then the hanging bracket is gradually moved to the upper end of the beam by the hanging bracket driving device. Move to the part side. Then, the outer wall material changes its posture at the bevel, and when the suspension bracket reaches the upper end of the beam, the outer wall material becomes vertical.

[0007] Therefore, the posture changing operation of the outer wall material can be performed in a series of steps, so that the labor and labor for the worker can be reduced, the working time can be shortened, and the operation can be performed safely. Further, since the outer wall material is not brought into contact with the floor or the like, there is no possibility of damaging the outer wall material.

Next, the suspension bracket 30 is moved by the geared motor 41, the suspension point bearing portion 31 is stopped on the center of gravity G of the entirety of the outer wall material 1 and the lifting device 10, and the crane is inserted into the hook hole 34a of the bracket body 34. And the outer wall material 1 is lifted. At this time, the outer wall material 1 is in a state of being suspended in the horizontal center of gravity. At this time, each of the bearings 36 and 39 comes into contact with each of the holding plates 23 of the beam 20.

Next, the suspension bracket 30 is gradually moved toward the upper end 28 of the beam 20 by the geared motor 41. The bearings 36 and 39 roll the respective holding plates 23 of the beam 20. Then, the outer wall material 1 gradually rotates around the suspension point bearing portion 31 of the suspension bracket 30, and inclines with the upper end surface 1a upward as shown in FIG. Then, when the suspension point bearing portion 31 reaches the upper end portion 28 of the beam 20 and further reaches the distal end portion, as shown in FIG. 7, the outer wall material 1 stands vertically, that is, the vertical gravity center suspension.

Therefore, in the posture changing operation of the outer wall material 1, the labor and labor for the operator can be reduced, the operation time can be reduced, and the operation can be performed safely. Further, since the outer wall material 1 is not brought into contact with a floor or the like, there is an advantage that the outer wall material 1 is not likely to be damaged.

Further, for example, in order to install the outer wall material 1 on a frame of a building or the like, a plurality of outer wall materials 1 are placed horizontally on each floor, and the posture is changed from a horizontal state to a vertical state as described above. Alternatively, it can be implemented by transferring the outer wall material 1 as it is by the crane while changing the posture.

When the outer wall 1 is lifted, if a balance cannot be maintained only with the above configuration, a counterweight may be attached to an appropriate position of the beam 20.
