PURPOSE:To facilitate work by providing a slope leg member whose top face tilts when it is put on a horizontal face and a lift device which changes the height of one end of the slope leg member by turning it. CONSTITUTION:A slope leg member 1 is put on a lift device 2 after the lift device 2 is put at a desired position of slab, and a slope plate 4 is provided on the slope leg member 1. Next, the slope leg member 1 is put on a support member 35 so that an upper tip section 33a of a male screw bar body 33 of the lift device 2 is stored in a hole 12a of a connecting member 12. Then, a screwdriver is inserted into a groove 34 of the male screw bar body 33 from the hole 12a of the slope leg member 1, and the male screw bar body 33 is turned for adjustment so that the top face of an end 11 of the slope leg member 1 becomes the height of double floor. Consequently, it is possible to simplify the height adjusting work and shorten the construction period. |
