Therefore, in such conventional construction methods, in order to install a toilet bowl, the method for installing the toilet bowl itself must be created at the same time as the toilet bowl construction, that is, simultaneous construction with the floor slab is required. Therefore, the construction work becomes large-scale and the work efficiency deteriorates, resulting in a large amount of time, labor, cost, etc. being spent on toilet construction.

Therefore, the present invention has been made in order to solve such conventional problems, and its purpose is that the installation of the toilet bowl to the floor is carried out separately and independently from the formation of the floor slab after the formation of the floor slab. To provide a method for constructing a Japanese-style toilet that simplifies the work of installing a toilet bowl, improves the work efficiency, and 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 an opening 1 that vertically penetrates the floor slab 2, and a stepped portion on the periphery of the opening. 1a, and a supporting frame 5 having an open upper surface and a locking flange 5b on the outer periphery of the upper end and a toilet locking portion 5c on the inner periphery is inserted into the opening 1, and the flange 5b is inserted into the support frame 5. A Japanese-style toilet bowl 6 is inserted into the stepped portion 1a from above the support frame 5, and a predetermined position on the outer periphery thereof is locked and supported by the locking portion 5c of the support frame 5, and the support frame 5 is locked. A fixing material 11 is filled from above the stepped portion 1a facing the flange 5b so as to be substantially flush with the floor surface, and a finishing layer 12 is applied to the upper surface.

According to this method, as long as an opening for installing the toilet bowl is provided when the floor slab is formed, subsequent installation of the toilet bowl can be performed independently and independently of the formation of the floor slab. Installing a toilet bowl is easy and can improve work efficiency.
