[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor pan level adjusting device for placing a floor pan of a unit bath on an installation base.

[0002]

2. Description of the Related Art Conventionally, adjustment bolts have been provided at four corner positions in a floor pan of a unit bath. FIG. 5 is a diagram showing a conventional technique. However, in the case of the conventional technique, nuts are formed at the four corners of the floor pan base 4 in the floor pan, and four adjustment bolts 3 are screwed onto the nuts. The adjusting bolt 3 is screwed from above by the long special screwdriver 2. However, the long special screwdriver 2 can be inserted from the side because the foundation 12 of the house is on the side of the installation base 5. Instead, by inserting the long special driver 2 from the driver insertion hole 13 provided in the floor pan assembly edge, the engaging projection 2a at the tip of the long special driver 2 is connected to the plus or minus portion of the adjustment bolt 3. , And the adjusting bolt 3 is screwed in a rotating manner.

[0003]

In the case of the prior art, since the adjusting bolt 3 is arranged in a narrow portion between the foundation 12 and the portion of the bathtub-side floor pan 1, it is engaged from the side. When the tip of the projection 2a and the upper end of the adjustment bolt 3 are aligned with each other, it is not possible to peep from the side, and the engagement projection 2a and the adjustment bolt 3 are aligned by looking through the driver insertion hole 13 directly above.
There was a problem that the two did not fit easily. The present invention is configured so that the engagement protrusion 2a and the upper end of the adjustment bolt 3 are easily matched.

[0004]

The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.
That is, in order to adjust the level between the floor pan and the installation base of the unit bath, a pipe-shaped guide cylinder 7 is provided at the head of the adjustment bolt provided at the corner on the floor pan side.

[0005]

When the floor pan is first placed on the mounting base 5 with the level raised, the mortar or the adhesive is first placed on the four mounting bases 5 before placing the floor pan. Apply 8 to about 40 mm. Before the mortar or the adhesive 8 hardens, the adjusting bolt 3 screwed to the nut portion of the floor pan base 4 is set as high as possible. In this state, the four adjusting bolts 3 are mounted on the mounting base 5. Place on. Next, while looking at the level controller, the four adjusting bolts 3 are shortened and adjusted in the direction of lowering the floor pan to obtain the level. Then, the adjustment is stopped at the position where the level comes out. As a result, the floor pan base 4 appropriately crushes the mortar or the adhesive 8 and the level comes out in a state where the mortar or the adhesive 8 is solidified.
Thus, a state in which the floor pan base 4 is supported by the solidified mortar or the adhesive 8 is created from the state supported by the base.

Next, an embodiment of the present invention will be described. 1 is a side sectional view showing a floor pan level adjusting device of the present invention, FIG. 2 is a plan view of the floor pan, and FIG. 3 is a perspective view of a long special driver 2, a pipe-shaped guide cylinder 7, and an adjustment bolt 3. FIG. 4 is a side sectional view showing an embodiment of the spiral guide tube 6, and FIG. This will be described with reference to FIGS. The floor pan of the unit bath is inserted into the base 12 of the bathroom part of the house, and four adjustment bolts 3 are screwed into nuts provided at the four corners of the floor pan 4 constituting the floor pan. Therefore, the mortar or the adhesive 8 is placed on the mortar or the adhesive 8 placed on the installation base 5 before the mortar or the adhesive 8 dries, with the adjusting bolt 3 extended out 40 mm or more. Since the mortar or the adhesive 8 has not been dried yet, the floor pan base 4 is deformed when it is lowered, and the floor pan base 4 is deformed.
Allow for the decline of The mortar or the adhesive 8 is placed in an undried state on the installation base 5 with a thickness of 40 mm or more.

Reference numeral 11 denotes a base ballast, and reference numeral 10 denotes a concrete floor. The mounting base 5 is placed at four corners on the concrete floor 10. The mortar or the adhesive 8 in an undried state is placed on the installation base 5, and the floor pan base 4 with the adjustment bolt 3 protruding thereon is placed thereon. The floor pan is composed of a floor pan base 4, a bathtub side floor pan 1, and a washing floor floor pan 14. A floor pan assembly edge 25 surrounding the washing floor floor pan 14 and the bathtub side floor pan 1 is provided. The driver insertion hole 13 is formed, and the adjustment bolt 3 is disposed at a position directly below the driver insertion hole 13. The floor pan assembly edge 25 is a portion on which the wall portion of the unit bath is placed. Then, the long special driver 2 is inserted from the driver insertion hole 13, the portion of the engaging protrusion 2a is engaged with the head of the adjustment bolt 3, and the level is output while turning the long special driver 2.

The embodiment in FIG. 3 will be described. In this embodiment, a pipe-shaped guide cylinder 7 is fitted over the adjustment bolt 3. The pipe-shaped guide cylinder 7 is used by inserting a cut pipe or hose of PVC. By inserting the pipe-shaped guide tube 7 into the head of the adjusting bolt 3 as described above, the upper end of the pipe-shaped guide tube 7 comes out above the base foundation 12. When the long special driver 2 is further inserted from the driver insertion hole 13 by aligning the engagement projection 2a with the pipe-shaped guide cylinder 7 at the position shown in FIG. It can be matched to the head. In the embodiment shown in FIG. 4, a spiral guide tube 6 is used instead of the pipe-like guide tube 7. The spiral guide cylinder 6 is also inserted into the head of the adjusting bolt 3, and its upper end is close to the upper end of the foundation 12.

[0009]

[Effects of the Invention] The present invention is constructed as described above, and has the following effects. That is, it is arranged at a position below a narrow portion sandwiched between the floor pan and the foundation base 12, and can be seen only through the driver insertion hole 13 formed in the floor pan assembly edge 25 at the top. In other words, the same effect as when the head of the adjustment bolt 3 is extended to a position about the upper surface of the foundation 12 is exerted. In addition, the engagement protrusion 2
If a is matched with the head of the pipe-shaped guide cylinder 7, the head of the adjustment bolt 3 and the engagement protrusion 2 a can be automatically matched by further inserting the long special driver 2. You can. If the adjusting bolt 3 is a long bolt, the same effect can be exerted. However, if the long bolt is screwed on the floor pan base 4, it is easy to bend in contact with an obstacle, and The cost of shaku bolts is high. In the present invention, the pipe-shaped guide tube 7 and the helical guide tube 6 which are inexpensive can substitute for this.
