  In the present invention, at least a part of the exposed surface of the Japanese-style toilet 10 may be scratched with an iron brush or the like prior to the attachment of the sheet 20 for preventing falling and scattering. If it does in this way, the joint strength of the sheet | seat 20 for fall and scattering and the Japanese style toilet bowl 10 will increase, and the holding strength of the Japanese style toilet bowl 10 will become very high.

  In the above embodiment, the fall and scattering prevention sheet 20 is constituted by a self-adhesive sheet. However, in the present invention, the fall and scattering prevention sheet 20 is constituted by a material other than the self-adhesive sheet and bonded. You may make it stick on the Japanese-style toilet bowl 10 with an agent.

  As the falling and scattering prevention sheet 20, various fiber mats such as a glass fiber mat, a metal fiber mat, and a carbon fiber (carbon fiber) mat impregnated with an adhesive may be used. In addition, a glass fiber mat is suitable from the viewpoint of cost, good handleability, and high holding strength of the Japanese-style toilet 10 after bonding. In this case, as the adhesive, an epoxy resin-based adhesive is preferable because of the high adhesive force between the glass fiber mat and the vitreous material on the surface of the Japanese-style toilet 10.

  Even when the sheet 20 for preventing falling and scattering made of glass fiber mat or the like is attached to the exposed surface of the Japanese-style toilet 10 with an adhesive, the exposed surface is rubbed with an iron brush prior to the attachment. Thus, by attaching at least a part of the exposed surface, preferably the entire part to which the adhesive is attached, the adhesive force between the scattering prevention sheet 20 and the Japanese-style toilet 10 can be increased.

  In the present invention, the adhesive may be used by adhering to or impregnating a fiber mat such as a glass fiber mat on site.

  In the present invention, prior to fitting the lid material 22 into the Japanese-style toilet 10, the Japanese-style toilet 10 may be filled with foamed resin beads.

  In this way, the Japanese toilet bowl 10 is filled with foamed resin beads, and the lid 22 is placed on the beads so as to be fitted into the Japanese toilet bowl 10, so that the lid 22 is filled. It can prevent falling in the Japanese style toilet bowl 10 by the weight of 23, a load on the floor, etc. Since the beads 26 are made of foamed resin and are lightweight, even if the beads 26 are filled into the Japanese-style toilet 10, the Japanese-style toilet 10 is not excessively loaded.

  Even if water enters the Japanese-style toilet 10, the beads 26 are filled in the Japanese-style toilet 10 in this way, so that water does not easily accumulate in the Japanese-style toilet 10, and the Japanese-style toilet 10 Even when the toilet 10 is damaged such as cracks, a large amount of water does not leak downstairs.

  In the present invention, the Western-style toilet 30 may be installed such that the front-rear direction at the time of installation is crossed with the front-rear direction of the Japanese-style toilet 10 originally installed in the toilet room. It may be made to become.

  In the above embodiment, after the high-strength plate 23 is installed, the self-hardening material 26 is supplied and leveled, but the self-hardening material 26 is first cut into the cut surface of the Japanese-style toilet 10 or the upper surface of the lid material 22. You may make it supply according to a level and level, and may install the high intensity | strength board 23 after that.
