According to the present invention, there is provided a leg fixing device, such as a pedestal, having a pair of right and left side walls extending over the entire length of each of inner surfaces of left and right side walls provided on a joist having a cross-sectional shape. Crosspiece, a washer member having mounting bolt insertion holes horizontally mounted on these crosspiece members, and a vertical piece and a horizontal piece having a screw hole are formed into an L shape, and the vertical piece is formed as described above. A mounting tool that can be fixed to the upper end of the leg to be fitted into the joist, a horizontal piece is superimposed on the washer member laid on the beam member, and a mounting bolt insertion hole of the washer member. And a mounting bolt which is screwed in a threaded manner into the screw hole of the horizontal piece superimposed on the washer member, and whose upper end is abutted against the upper wall of the joist material.

[0007]

In the leg fixing device having the above-mentioned structure, a washer member is horizontally mounted on a pair of right and left cross members provided on the joist, and the vertical piece of the fixture is fixed to the upper end of the leg. The upper end of the body is fitted from below the joist and the horizontal piece of the mounting tool is overlapped on the washer member, and the mounting bolt is inserted into the screw hole of the horizontal piece through the mounting bolt insertion hole of the washer member. When the upper end of the mounting bolt is screwed into the upper wall of the joist, the upper wall of the joist and the horizontal piece of the mounting tool are pushed away from each other as the mounting bolt is screwed. For this reason, the washer member is strongly sandwiched between the pair of cross members on the joist material side and the horizontal piece of the fixture, and the leg is fixed so as not to move. In the state where the leg is fixed in this manner, the mounting tool and the mounting bolt are housed in the inner space of the joist together with the upper end of the leg, and the washer member is also housed in the inner space of the joist. They are obscured by joists so that they cannot be seen from the outside.

In the state where the mounting bolt is loosened, the washer member can be slid on the pair of cross members on the joist material side. Therefore, the mounting bolt is loosened and the washer member is mounted on the cross member. It is possible to freely change the fixing position of the leg by sliding.
