[Effect of device]

Since the present invention is configured as described above, the mounting height of the floor plate can be adjusted from above or below the floor plate regardless of before and after the laying of the floor plate, and each floor plate has its own level. Adjustment is possible, high construction accuracy can be obtained, and moreover, the leg members are laid at the intersections of the vertical and horizontal dimension lines that match each floor board drawn on the foundation floor, and the screw bolts of each leg member are installed. Insert the screwed-in level adjustment nuts into the insertion holes formed in the corners of each floor plate, and receive each floor plate at the middle step of each level adjustment nut. The floor board material can be stably connected and supported.
Also, by using the body length nut as the level adjustment nut, the height of the floor board can be freely adjusted without replacing the leg member, and moreover, the body length nut can be adjusted from the upper end of the screw bolt of the leg member. By turning it as high as possible, the height of the adjustable range can be further expanded compared to the conventional unit column. Also, when the engaging part of the rotating tool is provided at the upper end of the insertion part of the level adjustment nut, the outer diameter of the insertion part is set as the outer diameter inscribed in the insertion hole of the floor plate material and It is possible to prevent the formation of a gap in the inner wall of the floor plate, and when the engaging part of the rotating tool of square tube shape is provided on the outer peripheral surface of the insertion part of the level adjusting nut, By molding the outer peripheral surface of the insertion portion having the outer diameter of the above so that the outer peripheral surface is square, the diameter of the outer peripheral surface is reduced, and the difference between the insertion hole of the floor plate and the level adjusting nut is reduced. Since the gap between the recess and the insertion portion can be made minute, there is an advantage that the finish can be improved.
