Thus, the scaffolding plate 1 is released from holding at the target position P2.

The second holding mechanism 10b is provided with arms 15 and 15 with claws that are opposed to each other by a driving source such as a longitudinal cylinder provided in the longitudinal frames 11a and 11a and rotated in the forward and backward directions. By rotating 15 in the advancing direction, the bottoms of the spar-side frames 3 and 3 of the scaffolding plate 1 located at the starting position P1 are held from the outside, and by rotating the arms 15 and 15 in the backward direction, The holding of the scaffold board 1 is released at the target position P2.

(Control device)
As shown in FIGS. 2 to 4, the airframe 11 is provided with a control device 16 for controlling the hanging bracket 8 of the scaffolding plate 1 during transfer.

In the case of the illustrated embodiment, the body 11 is provided with mount members 17 and 17 composed of a pair of rods extending in parallel with the long frame 11a, and the mount members 17 and 17 are bushes provided on the short frame 11b and the like. The bearing member 18 is slidably supported.

The control device 16 includes an attaching / detaching means 19 disposed so as to face the window hole 7 of the flooring 2 of the scaffold plate 1 when the machine body 11 holds the scaffold plate 1 by the holding mechanisms 10a and 10b. Up and down moving means 20 configured by a driving source such as a vertical cylinder that moves the attaching and detaching means 19 up and down, and a driving source such as a horizontal cylinder that moves the attaching and detaching means 19 forward and backward in the axial direction of the frame 5 of the scaffold plate 1. It is comprised by the comprised forward / backward moving means 21. FIG.

In the case of the illustrated embodiment, the control device 16 has a bracket 22 that supports the vertical movement means 20 fixed to the mount members 17 and 17 by a fixing means 23 such as a clamp, and the forward / backward movement means 21 includes: It is mounted on the short frame 11b of the body 11 and is connected to the vertical movement means 20 of the control means 16 located in the vicinity of the short frame 11b. Accordingly, the advancing / retreating movement means 21 is configured to move the mounting members 17, 17 along the shaft support member 18 together with the attaching / detaching means 19 and the vertical movement means 20.

At this time, as shown in the figure, the scaffolding plate 1 has a plurality of window holes 7 formed in the flooring 2 at intervals in the axial direction of the frame 5, and a hanging metal fitting 8 is provided facing each window hole 7. Correspondingly, as shown in FIG. 3, the control device 16 includes a plurality of units 16 a having the vertical moving means 20 and the attaching / detaching means 19 in the axial direction of the mount members 17, 17 at a predetermined interval. An advancing / retreating means 21 is provided which is fixed by the adhering means 23 with a gap and moves at least one unit 16a.

With this configuration, the plurality of units 16a are simultaneously moved in the axial direction of the frame 5 by sliding the mount members 17 and 17 through the at least one unit 16a by the forward / backward moving means 21. Since it can be moved forward and backward, it is not necessary to provide the forward / backward moving means 21 in all the units 16a arranged at intervals, and there is an advantage that it is sufficient to provide it in at least one unit 16a.

However, the present invention is not limited to such a configuration, and the mount members 17 and 17 are fixed to the airframe 11 so as not to be slidable, and the unit 16 a is slidable with respect to the mount members 17 and 17. It may be configured so that all the units 16a are individually moved forward and backward by the forward / backward moving means 21.

As shown in FIG. 4B, the attaching / detaching means 19 includes a groove member 25 having a groove portion 24 extending in the axial direction of the mount member 17 on the lower surface, and an electromagnet 26 is constituted by the groove member 25. . Therefore, the suspension fitting 8 is magnetically attached to the groove member 25 when the electromagnet 26 is turned on, and the suspension fitting 8 magnetically attached when the electromagnet 26 is turned off is separated from the groove member 25.

As shown in the figure, it is preferable that the cross-sectional shape of the groove portion 24 is formed with tapered surfaces 24b and 24b inclined downward and diverging from both sides of the concave portion 24a provided in the central portion.

(Operation of control device)
As described above, when the body 11 is lowered toward the starting position P1 and the scaffolding plate 1 is held by the holding mechanisms 10a and 10b, the attaching / detaching means 19 of the control device 16 is attached to the floor of the scaffolding plate 1 as shown in FIG. It faces the window hole 7 of the material 2.

From this state, as shown in FIG. 6, the attachment / detachment means 19 is moved downward by driving the vertical movement means 20, and the upper arc portion 8 b of the hanging metal fitting 8 is magnetized by turning on the electromagnet 26. Although only the top part of the upper arc part 8b is slightly exposed from the window hole 7 in the hanging metal fitting 8, according to the illustrated embodiment, the recess 24a of the groove member 25 constituting the attaching / detaching means 19 is formed in the upper arc part 8b. Since the taper surfaces 24b and 24b are in contact with the two sides on both sides of the top of the upper arc portion 8b in an oblique state, the suspension fitting 8 is magnetically attached so that it can be pulled up.

Next, as shown in FIG. 7, when the vertical movement means 20 is driven and the attachment / detachment means 19 is moved upward in a state where the hanging metal fitting 8 is magnetically attached, the hanging metal fitting 8 is pulled up from the window hole 7 (above-mentioned Pulling process). At this time, the lifting is preferably performed so that the lower arc portion 8c of the hanging metal fitting 8 does not contact the lower surface of the frame 5, that is, the frame 5 is positioned between the upper arc portion 8b and the lower arc portion 8c. .

Next, as shown in FIG. 8, when the advancing / retreating means 21 is driven and the attaching / detaching means 19 is advanced in the axial direction of the frame 5 with the hanging metal fitting 8 magnetized, the hanging metal fitting 8 tilts. Thus, the inclined posture X is set (the tilting step). As described above, the hanging metal fitting 8 is lifted to such an extent that the lower circular arc portion 8c does not contact the lower surface of the frame 5, so that the hanging fitting 8 accompanies in the forward direction while being magnetically attached to the attaching / detaching means 19 as shown in the figure. However, it abuts against the edge of the window hole 7, and the lower arc portion 8 c is tilted toward the direction of contacting the lower surface of the frame 5 with the corresponding contact portion as a fulcrum.

In order to ensure that the hanging fitting 8 is tilted, the attaching / detaching means 19 advances to the overrun position F even after the hanging fitting 8 is set to the inclined posture X as shown by a chain line in FIG. It is preferred that As described above, the groove member 25 constituting the attaching / detaching means 19 has the tapered surfaces 24b, 24b in point contact with both sides of the upper arc portion 8b of the hanging metal fitting 8 in an oblique state, so that it resists magnetic force. The upper arc portion 8b can slide while rubbing along the groove portion 24. That is, the groove member 25 can be advanced to the overrun position F even when the hanging metal fitting 8 is constrained to the state of the inclined posture X in which the lower arc portion 8c is in contact with the lower surface of the frame 5. It is configured as follows.

The pulling-up process and the tilting process are performed while the machine body 11 holding the scaffold plate 1 is transferred from the starting position P1 to the target position P2. Then, the airframe 11 is lowered toward the target position P2, and the pressing step of pressing down the hanging bracket 8 is performed immediately before or immediately after the transferred scaffold plate 1 is placed on the lower scaffold plate 1x.

As shown in FIG. 9, the attaching / detaching means 19 is lowered by driving the vertical movement means 20 in a state where the hanging fitting 8 is magnetically attached, and is pushed down while the hanging fitting 8 is in the inclined posture X ( The pressing step). As shown in FIG. 9B, when the hanging fitting 8 is pushed down in the inclined posture X, it may be displaced in the direction of increasing the inclination angle by coming into contact with the edge of the window hole 7. As described above, since the upper arc portion 8b is slidable along the groove portion 24 against the magnetic force by the point contact of the taper surfaces 24b and 24b, the suspension fitting 8 is provided. As shown in FIG. 9 (C), it is preferably pushed down in the inclined direction while sliding on the groove 24.

After placing the scaffolding plate 1 on the lower scaffolding plate 1x, the attaching / detaching means 19 detaches the suspension fitting 8 by turning off the electromagnet 26, and then moves up and down the moving means 20 and retreats the advancing / retreating moving means 21. , Returned to the original position.

As described above, the transferred scaffold plate 1 is placed on the lower scaffold 1x in a state in which the hanging metal fitting 8 is suitably stored in the lower space. That is, it is placed on the spar-side frame 3 of the lower scaffolding plate 1x in a state where the spar-side frame 3 of the scaffolding plate 1 is in contact, and by repeating the above, from the starting position P1 to the target position P2, By sequentially transferring the scaffold plate 1, a large number of scaffold plates are laminated in a stable state.
