(1) First, in step (c), a series of steps including attaching a support frame to the opening, attaching a Japanese-style toilet to this support frame, and applying a non-drying sealant to the gap between this Japanese-style toilet and the support frame. It is troublesome to carry out the work one after another at the construction site, and if possible, the efficiency of the construction work can be improved if a series of these works can be performed all at once at the construction site.

(2) Next, when attaching the Japanese-style toilet to the support frame in step (c), the height of the installation is determined by the height position of the support part of the support frame, so it is difficult to make subtle height adjustments of the toilet. becomes.

(3) Also, when connecting piping in step (d),
Since the position of the piping connector is determined by the mounting position of the support frame, that is, the opening position provided in the base slab, it will be difficult to connect the piping later unless the series of operations for the piping position are performed accurately.

(4) Furthermore, in step (e), mortar and a waterproof layer are applied on the base slab, and then mortar is applied again, and then a finishing layer is applied.The work is complicated and the work area is wide. Therefore, the work is troublesome and increases costs.

(5) Furthermore, the work of removing the attached formwork in step (b) is troublesome, and if this work could be omitted, the work efficiency would be further improved.

Therefore, this invention was made in order to solve such conventional problems, and its purpose is to quickly and easily install a Japanese-style toilet, and also to easily adjust its height and connect piping. To provide a method for constructing a Japanese-style toilet bowl that can be carried out at low cost.

(Means and Effects for Solving the Problems) In order to solve the above problems, the method for constructing a Japanese-style toilet according to the present invention provides a method for constructing a Japanese-style toilet 5 by attaching a predetermined position on the outer circumference of the Japanese-style toilet 5 to a fireproof cover 6 having a substantially box-like shape. The fireproof cover 6 has a height adjustment mechanism 1 at a predetermined position on the outer periphery of the fireproof cover 6.
2, and at the bottom thereof, a through hole 61 for connecting the drain port 13a of the Japanese style toilet 5 to the piping 15,
