It is formed with a necessary number, for example, vacuum suction pads 47 arranged at 4 to 6 places at appropriate positions on the front side surface.

Reference numeral 49 in the drawing denotes an operation unit for adjusting the flow rate of the supply air to the cylinder 35 and the like, and for evacuating the vacuum suction pad 47 to give suction force to the vacuum suction pad 47. The required control for each required site connected via the book piping system 48 is possible. The vacuum generator for the vacuum suction pad may be attached to the suction attachment device.

Next, a method for constructing a glass sheet as a plate-like object at a construction site of a building by using the plate-like object applying apparatus of the present invention will be described.

First, the construction apparatus A of the present invention is carried into a room where a glass plate is not yet attached to the outer wall, window or opening above the floor where the glass plate is constructed, for example, the room on the first floor or the second floor above,
The carriage main body 1 is fixed to the floor by traveling to a predetermined position and lowering the supporting leg 10. The suction attachment device 5 is moved to the position of the pallet of the glass plate previously carried to the floor by raising and lowering the swing mast 2, turning up and down, raising and retracting the telescopic arm 3, and hoisting and rewinding the wire 4. The vacuum suction pad 47 is brought into contact with the glass plate G surface using 31.

At this time, since the position adjusting mechanism 31 capable of adjusting the position in any direction is interposed in the suction attachment device 5, even if the glass plate G has an inclination and is leaned against the pallet, its inclination is increased. The suction pad 47 can be brought into close contact with the angle according to the angle. In this way, the suction pad 47 is brought into close contact with the suction pad 47, and then the glass plate G is held by the suction holding portion 30 by drawing air to suck the suction pad 47.

Next, the suction attachment device 5 to which the glass plate G has been sucked performs necessary operations such as raising and lowering of the lifting mast 2, swinging, raising and lowering and stretching of the telescopic arm 3, winding and rewinding of the wire 4, and rotation of the suction attachment device 5. At the very least, the glass plate, wall material, window frame, and other unconstructed outer wall surfaces are moved from the space to the outside, and are guided to a substantially accurate position in the place to be constructed.

When the suction attachment device to which the glass plate is sucked is taken out of the outdoors, the glass plate G is operated by an operator of an outdoor workbench such as a gondola to operate the position adjusting mechanism 31 which is arranged to move forward or backward. Is applied to the tilt adjusting section 32, the rightward or leftward tilt is given to the left and right adjusting section 34, and the rotation in the plane direction with respect to the glass plate G is adjusted by the rotation adjusting section 33.
The respective positions are finally adjusted with respect to the position to be constructed, and further the predetermined work of attaching the glass plate G is performed. The final position adjustment work of the glass plate can be easily performed from the outdoor side by passing the operation handle of the suction attachment device to the outdoor worker. Further, when such a mounting work is completed and the user is going to evacuate to the rooftop, the work opposite to the work of moving the glass plate to the outside is performed to carry out the suction attachment device 5.
Put the inside indoors and do the next work.

[Effects of the Invention] As described above, according to the present invention, the elevating mast is in the lowered position, the telescopic arm is in the lowered position, and the electrically driven traveling device is actuated so that the building is relatively narrow. In addition to being able to easily carry in the construction equipment indoors, the suction attachment of the plate-shaped body is performed by the necessary operations such as raising and lowering of the lifting mast, turning up and down of the telescopic arm, raising and retracting the telescopic arm, and winding and rewinding the wire The suction work to the device, the movement work of the plate-shaped body to the outside, the position adjustment work to the construction site of the plate-shaped body, and the construction work of the plate-shaped body can be easily performed. Moreover, the work range can be widened by selecting the above-mentioned various operations, and can be applied to various construction sites by various operations. Further, since the plate-like body held by the suction holding unit can be adjusted in position in any direction by the position adjusting mechanism interposed therebetween,
Even a plate-shaped body such as a plate glass plate having a large size and weight can be easily operated by an operator on a workbench outdoors, and the plate-shaped body can be easily constructed.

Therefore, a large plate with a large size and weight can be constructed by a small number of people, and the position adjustment mechanism has a degree of freedom such as vertical alignment, angle adjustment, etc., which is manually performed by a worker, so that a plate The body can be finely positioned, which facilitates the construction of the plate-shaped body on the window frame, the spandrel attachment member, various other construction members, and the construction structure.

As described above, the construction device of the present invention is placed on the floor surface of the floor above the floor where the construction is performed at the construction site of the building, the plate-like body is made to adsorb the adsorption attachment device, and the outer wall portion of the floor is not adsorbed. It is possible to take out the suction attachment device indoors and outdoors using the construction part, pull it down to the construction site downstairs, adjust the construction position, and work from the outside can be done by a worker only on the workbench. Therefore, it is not necessary to use a scaffold for exterior work, the construction time is shortened, and the safety and workability are high.
