Since the height of the flange (13) supporting the bracket (19) changes, the level is adjusted accordingly. Adjustment of this level can be easily performed from above the bracket (19) and is not hindered by the floor plate (16) inside the fixing base (2).

To adjust the position of the outer wall panel 18 in the left-right direction, loosen one of the left and right nuts 42 of the head left-right adjuster 37 and rotate the other in the tightening direction. The left and right adjuster (37) cannot be moved 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) The outer wall panel (18) will move in the same direction within the length of the bolt hole (23).
Is changed. This left-right 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 its male screw rod (30) into the left and right slits (27) and (27) of the leg support member (25). Insert the leg support bolt (44) into the bolt hole (34) of (35), and insert the tip of the leg support bolt (44) from the notch (29) portion, the outer wall panel (18) supported on the head side as described above. Screw it into the screw hole (45) at the lower end and fix it. 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, outside the insert nut (46), a rectangular contact plate ( 47) are installed so as to be exposed on the back surface of the outer wall panel (18).

The notch (49) is interposed between the (8) and the abutment plate (4) such that the notch (49) is fitted to the leg support bolt (44). This adjustment liner (48) uses different thickness,
Alternatively, by changing the number of sheets to be inserted, the distance between the plate (47) and the central piece (28) is changed, thereby
(18) The legs are adjusted in and out.

To adjust the left and right positions of the legs of the outer wall panel (18), one of the nuts (36) and (36) at both ends of the male screw rod (30) of the leg left and right adjuster (32) is loosened. When the other is screwed in the tightening direction, the left / right adjustment tool (32) moves in the left / right direction with respect to the leg support member (25), so that the leg support bolt (44) is moved within the range of the cut (29). It will move and the position of the legs will be adjusted. In the event of a horizontal force during an earthquake, the leg support bolts (44)
The rocking operation in which the panel (18) swings left and right while sliding up and down within the range of (34) is allowed.

In the above description, both the head left-right adjustment tool (37) and the leg left-right adjustment tool (32) are screwed with nuts (36, 42) at the ends of the externally threaded rods (30, 40). Then, the left and right adjustment and positioning are performed by rotating the nuts (36) and (42) .For example, a bolt is screwed into the plate material (35) (39) side, and the bolt is tightened. It is also conceivable to perform the rotation. In short, these adjustment tools (37) and (25) are only required to be able to be moved in the left and right directions by the screw mechanism with respect to the bracket (19) and fixed at an arbitrary position.

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 restrained, the plate member (39) may be directly mounted on the flange (13) of the head support bolt (14). Further, the flange (13) may be, for example, a nut fixed thereto, regardless of the circular shape as shown in the figure. Further, it is conceivable to adjust the height with the nut as a support with the nut, but in that case, the work has to be performed on the back side of the horizontal portion (21), so that the work is somewhat troublesome.

[0030]

As described above, according to the present invention, the leg supporting portion at the lower end of the outer wall panel suspended and supported by a beam or the like is provided on the bracket for supporting the lower outer wall panel head, and this leg portion is provided. Since it can be fixed with the left and right adjustment tool of the support part adjusted in the left and right direction, the wall panel can be moved up and down at the legs while avoiding interference between the dry joint materials like a wall panel with dry joint materials pre-installed. Or, it can be fixed by adjusting the position up and down and left and right so that the dry joints are closely attached to each other. There is an effect that the construction work of the outer wall panel to which the material is attached can be performed extremely easily.

Further, since the left and right positions of the wall panel legs are adjusted with the screw portion of the left and right adjusting tool, fine and fine adjustment is possible, and the panel can be moved while rotating the screw portion. Since it is possible, there is no need to move the panel by hand, and the adjustment work is easy.

Further, by providing the support member for supporting the leg portion of the outer wall panel on the bracket side of the outer wall panel, the support member is located at a position distant from the fixed base supporting the head of the lower outer wall panel. Because the leg support part comes, the adjustment of the head and the adjustment of the leg at the fixed base part can be performed at a distance from each other without interfering with each other, and each work is not disturbed by obstacles It can be done easily.
