PURPOSE: To increase dimension accuracy of a backing wall.
CONSTITUTION: Side panels 12, 14 are fixed so that these are projected from a wall panel 10 and a front panel 16 is fixed at the front face of the side panels 12, 14. And joint metal blocks 38 are attached to the upper part of the side panels 12, 14 and the distance between the side panels 12, 14 can be adjusted by long bolts 52. And L angles 51 are fixed to be adjustable in the level by a long hole 51c and bolts 53 at the rising piece 41 of the joint metal blocks 38. And the upperface panel 18 is placed on the L-angles 51 to fix by screws 62 with blades. And hence, the distance between the side panels 12, 14 can be adjusted accurately by turning the long bolts 52 and the height of upperface panel 18 can be adjusted.
