As described above, when the outer wall panel (18) is supported, in order to adjust the vertical level of the outer wall panel (18), the hexagonal hole (15) at the upper end of the support bolt (14) is pushed from above. When you lock the tool and rotate this support bolt (14),
Since the height of the brim (13) supporting the bracket (19) is changed, this adjusts the level. This level adjustment can be easily done from above the bracket (19) and is not disturbed by the floorboard (16) inside the fixed base (2).

To adjust the lateral position of the outer wall panel (18), loosen one of the left and right nuts (42) (42) of the head left and right adjuster (37) and rotate the other in the tightening direction. The left and right adjusters (37) themselves cannot move because the bolt holes (38) of the plate material (39) are fitted to the support bolts (14), and as a result, the horizontal portion of the bracket (19) is The outer wall panel (18) will move in the same direction within the length of the bolt hole (23).
The left and right position of will change. This right / left adjustment can be easily performed because it is only necessary to rotate the nut (42) from the outside of the bracket (19).

On the other hand, the leg left and right adjusting tool (32) is installed by inserting the male screw rod (30) into the left and right slits (27) and (27) of the leg supporting member (25). Insert the leg support bolt (44) into the bolt hole (34) of (35), and from the notch (29) portion of the tip, the outer wall panel (18) supported on the head side as described above. Secure it by screwing it into the screw hole (45) at the lower end. As shown in FIG. 3, the screw hole (45) is formed by an insert nut (46) embedded in the outer wall panel (18), and further, on the outside of the insert nut (46), a rectangular contact plate (45) is formed. 47) is installed so as to be exposed on the back surface of the outer wall panel (18).

A notch (49) is interposed between the leg plate support bolt (44) and the contact plate (4) between the contact plate (8) and the contact plate (4). This adjustment liner (48) is different in thickness,
Alternatively, by changing the number of inserted sheets, the distance between the contact plate (47) and the center piece (28) is changed, and thus the outer wall panel is changed.
The entrance and exit of the leg of (18) are adjusted.

To adjust the left and right positions of the legs of the outer wall panel (18), loosen one of the nuts (36) (36) at both ends of the male screw rod (30) of the leg left and right adjuster (32). , If the other is screwed in the tightening direction, the left / right adjusting tool (32) moves left / right with respect to the leg supporting member (25), so that the leg supporting bolt (44) is within the range of the notch (29). By moving, the position of the legs will be adjusted. For horizontal force during an earthquake, this leg support bolt (44)
The panel (18) is allowed to rock in the left-right direction while sliding vertically within the range of (34).

In the above, the head left / right adjuster (37) and the leg left / right adjuster (32) are both screwed with nuts (36) (42) at the ends of the male screw rods (30) (40). Then, the left and right are adjusted and positioned by the turning operation of the nuts (36) (42) .For example, a bolt is screwed into the plate material (35) (39) side and the bolt It is also conceivable to perform the rotation. In short, these adjusting tools (37) and (25) may be those that can move in the left-right direction with respect to the bracket (19) by the screw mechanism and can be fixed at arbitrary positions.

Alternatively, the head left / right adjuster (37) has a structure in which it can be pulled out upward at the slit (31) as shown in the figure, but by some means so as not to move upward with respect to the bracket (19). If constrained, the plate material (39) may be placed directly on the collar (13) of the head support bolt (14). Further, the collar (13) may be fixed to a nut, for example, regardless of the circular shape as shown in the figure. Further, it is conceivable to adjust the height with the nut as the support with the nut, but in that case, the work must be done on the back side of the horizontal part (21), which makes the work a little troublesome.

[0032]

As described above, according to the present invention, the vertical height of the wall panel can be adjusted by the support bolt portion for suspending and supporting the wall panel, and the head left / right adjuster can also be used for the same wall. It is possible to adjust the position of the panel in the left-right direction, and thus, while avoiding interference between the dry joint materials, like a wall panel with dry joint materials pre-installed,
Since the wall panels can be installed vertically or horizontally apart from each other and displaced, and then fixed while adjusting the positions vertically and horizontally so that the dry joint materials are in close contact with each other. There is an effect that the construction work of the outer wall panel to which such a dry joint material is attached can be performed extremely easily.

The adjustment of the left and right positions of the wall panel is performed by the screw part of the left and right adjusting tool provided on the bracket.
Fine adjustment is possible, and since the panel can be moved while rotating the screw part, it is not necessary to move the panel by hand, and the adjustment work is easy.

On the other hand, the screw adjustment of the support bolt portion for height adjustment is performed by engaging the tool locking hole at the upper end of the support bolt and rotating the support bolt to easily perform work from above. In addition, by providing a support member that supports the leg portion of the outer wall panel on the bracket side of the outer wall panel, compared to the case where the support member is provided on the fixed base around the support bolt, the rotation operation of the tool is hindered. There is no such thing, and the work becomes easier.
