Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a bathroom unit comprising a bathtub and a bathroom substrate to which the bathtub is combined.

Generally, a bathroom unit has a bathroom board 3 having a washing area 1 and a bathtub mounting part 2, as shown in FIG.
The bathtub 4 is combined to form a bathroom unit, and the bathtub 4 is inserted into the mounting opening 5 of the bathtub mounting part 2 from above, and its flange 6 is brought into contact with the upper surface of the mouth edge of the mounting opening 5, and the said abutment The joints were glued together with adhesive.

With such a structure, a step is created by the flange 6 on the bathtub attachment part 2, and the adhesive protrudes onto the surface, reducing the commercial value.

For this reason, we have considered bonding the bathtub 4 to the bottom surface of the bathtub mounting portion 2 of the bathroom board 3. By the way, since the bathtub 4 has a fairly large shape, it is necessary to fix it in position using a large jig or mold when gluing it, which increases the size of the manufacturing equipment and does not make the work easy. .

SUMMARY OF THE INVENTION The present invention has been made in consideration of these problems, and an object of the present invention is to easily connect a bathtub to a bathroom board. In order to achieve this object, the present invention provides a bathtub opening in the bathtub attachment part of a bathroom board, and also provides an annular hanging wall along the mouth edge of the bathtub opening, and provides the annular hanging wall on the lower surface of the bathtub attachment part. A plurality of fixing base materials are glued so as to be located on the outside of the wall, the top surface of the flange of the bathtub is brought into contact with the lower end of the annular hanging wall, and the flange is temporarily fixed to the fixing base material with screws. A method for manufacturing a bathroom unit, in which the recess formed by the bathtub attachment part, the annular hanging wall, and the flange and the lower part of the flange are filled with an adhesive made of an adhesive thermosetting resin and solidified to join the bathtub and the bathroom board. It is.

According to this manufacturing method, no fixing jig or fixing mold is required when bonding large-sized bathtubs.
The manufacturing equipment is simplified and manufacturing is easy. Of course, the bathtub is firmly fixed to the bathroom board, and there is no step on the top surface of the bathroom board.
It has the advantage of good drainage and easy cleaning.

An embodiment of the present invention will be described below based on FIGS. 2 to 4.

In the figure, reference numeral 7 denotes a bathroom board made of reinforced fiber resin, which integrally has a washing area 8, a side wall 9, and a bathtub mounting part 10 formed above the washing area 8. The bathtub mounting portion 10 is formed with a bathtub opening 12 having an annular hanging wall 11 along the mouth edge. A plurality of fixing base materials 13 made of wood are arranged on the lower surface of the bathtub attachment part 10 and near the outer periphery of the annular hanging wall 11 so as to surround the annular hanging wall 11 at appropriate intervals. It is fixed to the bathtub attachment part 10 of the fixation base material 13 by applying an adhesive coating film 14 to the fixation base material 13 and the bathtub attachment part 10 . Reference numeral 15 designates a metal bathtub, the upper edge of which protrudes outward and whose outer shape matches the bathtub opening 12.
It has a flange 16 larger than the size of.
This flange 16 has a hanging piece 17 over the entire outer circumference.
are connected. A side plate 18 is bonded to the bathroom board 7 so as to surround the annular hanging wall 11 of the bathtub opening 12. The lower part of the annular hanging wall 11 is brought into contact with the upper surface of the flange 16 of the bathtub 15, and the flange 16 and the annular hanging wall 11 are bonded with caulking material 19, and the flange 1 is attached with screws 20.
6 is temporarily fixed to the fixing base material 13. and the side plate 18, the lower surface of the bathtub attachment part 10, and the annular hanging wall 11.
An adhesive 21 made of an adhesive thermosetting resin such as polyurethane, epoxy, or polyester is injected into the recess formed by the flange 16 of the bathtub 15 and the space between the side plate 18 and the lower surface of the flange 16 of the bathtub 15, and After curing, the flange 16 of the bathtub 15 is fixed to the lower part of the bathtub attachment part 10 with the flange 16 and hanging piece 17 wrapped in the adhesive 21.

Note that 22 in the figure is a support member, and 23 is a contact member that is fixed to the outer bottom of the bathtub 15 and comes into contact with the support member 22.

In the above, since the flange 16 of the bathtub 15 is temporarily fixed to the fixing base material 13, the adhesive 21
When injecting, the bathtub 15 is accurately fixed without shifting, and no special jig or mold is required for temporary fixing, so manufacturing equipment is simplified and manufacturing is easy. It is. Furthermore, since the flange 16 of the bathtub 15 is attached to the lower side of the bathtub attachment part 10 of the bathroom board, there is no step caused by the flange 16 on the upper surface of the bathtub attachment part 10, and water drainage and cleanability on the upper surface of the bathtub attachment part 10 are improved. It has the advantage that there is no adhesive leakage.

In addition, as shown in FIG. 2, there is a wall 24 rising from the washing area 8 on the side of the washing area 8 of the bathtub 15.
The side plates 18 are attached to the other three sides of the bathtub 15 excluding the wall 24 side.
Shape it so that it surrounds the two outer sides. In addition, in the case where a mold is used when injecting the adhesive 21, the side plate 18
may be omitted.

As explained above, according to the present invention, the bathtub can be easily and reliably fixed to the bathroom board, and its value is great.
