When the member 3 is opened and the bearing member 23 is pushed in, the movable holding member 3 side of the panel material P is released (see FIG. 2C).

After the panel material is installed, when the second signal for releasing the gripping member 6 is sent and the manual valve 111 is opened, the solenoid 101b operates to hold the gripping member through the circuit 114 and the circuits 115a and 115b. The pressure oil is supplied to the contraction operating side of the cylinder 9, and the pressure oil is returned from the circuits 108a and 108b via the manual valve 111, and the gripping cylinder 9 operates in the contraction direction to move the fixed clamping member 4 side. The grip member 6 is opened to release the panel material (see FIG. 2 (d)).

As described above, according to the present hydraulic circuit, since each operation described above can be performed by one set of solenoid valves, as compared with the case where a single circuit having a solenoid valve is formed for each cylinder. The number of control signals can be reduced, and the control circuit can be configured with a simple control circuit.

In addition, in the above-mentioned embodiment, in order to prevent the panel material from dropping due to vibration during transportation, a gripping member is provided at the tip of each sandwiching member so that the panel material is securely held. However, even if the gripping member is provided only on the fixed holding member side, the carrying and construction can be performed in the same manner, so that the gripping member on the movable holding member side can be omitted.

Further, in the above embodiment, one of the sandwiching members is fixed to the frame and only the other is formed so as to be rotatable and movable. However, both sandwiching members should be formed so as to be rotatable and movable on the frame. This allows the panel material to be installed in both directions.

Further, in the above-mentioned embodiment, an example in which the wall material is applied as the panel material has been described, but depending on the structure of the work vehicle or the like in which the panel material gripping device is mounted, various types of ceiling material and other materials can be used. Of course, it can also be applied to the construction of panel materials.
