DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, three or more cylindrical protrusions 2 are formed on the surface of a floor pan 1 such as a bathroom. As shown in FIG. 2, the convex portion 2 projects to the back side of the floor pan 1. A through hole 2 a extending from the front surface of the floor pan 1 to the back surface of the floor pan 1 is formed in the convex portion 2. A plurality of reinforcing ribs 3 are formed on the back surface of the floor pan 1 so as to connect to the portions of the protrusion 2 that project to the back surface side of the floor pan 1.

As shown in FIG. 2, a cylindrical member 4a having a screw hole 4a ₁ formed on the inner surface thereof, a flange 4b formed on the outer surface of the central portion of the cylindrical member 4a in the longitudinal direction, and the cylindrical member 4a. The nut member 4 having a plurality of reinforcing ribs 4c extending from one end portion to the outer edge of the flange 4b is provided with the nut 2 having a portion from the other end portion of the tubular member 4a to the flange 4b. Through hole 2a of the portion projecting to the back side of floor pan 1
In addition, the floor pan 1 is fitted from the back surface side, and the flange 4b is brought into contact with the end of the portion of the convex portion 2 projecting to the back surface side of the floor pan 1. As shown in FIGS. 2 and 3, a plurality of pairs of sandwiching plates 4d formed on the flange 4b in the same number as the reinforcing ribs 3,
The nut member 4 is locked to the floor pan 1 by sandwiching the reinforcing ribs 3, respectively.

As shown in FIG. 2, a height adjusting support bolt 5 having a slot 5a is screwed into the screw hole 4a ₁ of the tubular member 4a from the back side of the floor pan 1. A full locking screw bolt 6 having a slot 6a is screwed into the screw hole 4a ₁ of the tubular member 4a from the front surface side of the floor pan 1 and is in contact with the height adjusting support bolt 5. Tap bolt 7, is inserted from the surface side of the floor pan 1 into the through hole 2a of the convex portion 2 is screwed into the screw hole 4a ₁ of the tubular member 4a. The head portion 7 a of the headed bolt 7 is in pressure contact with the convex portion 2 via the packing 8 and covers the through hole 2 a of the convex portion 2.

The procedure for adjusting the height of the floor pan by the height adjusting apparatus for the floor pan according to this embodiment having the above-mentioned structure will be described with reference to FIG. With the floor pan 1 turned upside down and the back side facing up,
The nut member 4 is fitted to a portion of the convex portion 2 that projects to the rear surface side of the floor pan 1, the reinforcing ribs 3 are sandwiched between the pair of sandwiching plates 4d, and the nut member 4 is locked to the floor pan 1. The height adjusting support bolt 5 is screwed into the nut member 4 from the back surface side of the floor pan 1. The floor pan 1 is turned upside down, the back surface is faced downward, and the floor pan 1 is placed on the floor surface A of the building frame. The height of the floor pan 1 is adjusted by engaging the slot 5a of the adjustment support bolt 5 and appropriately rotating the height adjustment support bolt 5 by the driver B.

After the height adjustment of the floor pan 1 is completed, the locking full-screw bolt 6 is screwed into the nut member 4 from the front surface side of the floor pan 1 through the through hole 2a of the projection 2 to form the projection. Driver B inserted from the front side of floor pan 1 into through hole 2a of 2
The full screw bolt 6 for locking is screwed into the nut member 4 by using, and the full screw bolt 6 for locking is brought into contact with the support bolt 5 for height adjustment to lock the support bolt 5 for height adjustment. The head bolt 7 is inserted into the packing 8, and further inserted from the front surface side of the floor pan 1 into the through hole 2a of the convex portion 2 and screwed into the nut member 4, and the head 7a of the head bolt 7 is inserted through the packing 8. The head portion 7a of the headed bolt 7 covers the through hole 2a of the convex portion 2 to seal the through hole 2a and fix the nut member 4 to the floor pan 1.

By the above work, the height adjustment of the floor pan 1 and the lock of the height adjustment support bolts 5 after the height adjustment,
The sealing of the through hole 2a of the convex portion 2 is completed. Since the load from the floor pan 1 is applied to the height adjusting support bolt 5, the height adjusting support bolt 5 rotates in the direction of coming out of the nut member 4 even if the floor pan 1 is vibrated by an earthquake or the like. There is no fear. On the other hand, the rotation of the height adjusting support bolt 5 in the direction of biting into the nut member 4 is prevented by the locking full screw bolt 6 that abuts on the height adjusting support bolt 5. That is, the height adjusting support bolt 5 is locked by the locking full screw bolt 6.

In the floor pan height adjusting device according to this embodiment, the height adjusting support bolts 5 are provided from the front surface side of the floor pan 1.
Can be operated. In the floor pan height adjusting device according to the present embodiment, the headed bolt 7 is inserted into the through hole 2a of the convex portion 2 from the front surface side of the floor pan 1 and screwed into the nut member 4,
The nut member 4 can be firmly fixed to the floor pan 1 by pressing the head portion 7 a of the headed bolt 7 against the convex portion 2. As a result, the nut member 4 is firmly fixed to the floor pan 1 even under a strong impact load due to an earthquake or the like,
The situation where the floor pan becomes unstable is prevented.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, if you can sufficiently stop the water in the through hole for driver insertion,
Instead of forming the convex portion on the floor pan surface and forming the through hole in the convex portion, the through hole may be directly formed in the floor pan. In this case, the head bolt is screwed into the nut member from the floor pan surface side, and the head of the head bolt is pressed against the floor pan surface to close the through hole of the floor pan, thereby fixing the nut member to the floor. Not only can it be firmly fixed to the pan, but the water in the through holes can be stopped.

[0017]

As described above, in the floor pan height adjusting device according to the present invention, the height adjusting support bolt can be operated from the floor pan surface side. In the floor pan height adjusting device according to the present invention, the headed bolt is inserted into the through hole of the convex portion from the floor pan surface side and screwed into the nut member, and the head of the headed bolt is pressed against the convex portion. Thereby, the nut member can be firmly fixed to the floor pan.

If the through hole for inserting the driver can be sufficiently stopped, instead of forming a convex portion on the surface of the floor pan and forming a through hole in the convex portion, the through hole is directly formed in the floor pan. You may form. In this case, the head bolt is screwed into the nut member from the floor pan surface side, and the head of the head bolt is pressed against the floor pan surface to close the through hole of the floor pan, thereby fixing the nut member to the floor. Not only can it be firmly fixed to the pan, but the water in the through holes can be stopped.
