[Detailed description of the device] [Industrial applications]

The present invention relates to a waterproof floor pan that forms the floor of a bathroom.

2. Description of the Related Art A bathroom unit is formed by assembling a waterproof floor pan, a wall panel, and a ceiling panel, and the waterproof floor pan forming the floor of the bathroom unit is a bathtub mount for installing a bathtub. It is composed of a storage part and a washing part which is the floor of the washing part. The conventional waterproof floor pan is made of FRP, stainless steel, or the like, in which the bathtub mounting portion and the washing area are integrally formed.

[Problems to be solved by the device]

However, if the waterproof floor pan is formed by integrating the bathtub placement part and the washing place part in this way, the whole size becomes large, making it difficult to manufacture and the workability such as carry-in and installation at the construction site is poor. In particular, when the entire size is increased, it becomes difficult to align the drainage part formed in the waterproof floor pan with the drainage pipe, and the workability is deteriorated in terms of pipe connection. In order to solve this problem, the applicant for utility model registration filed Japanese Patent Application No. 63-61344. This is to separately form a bathtub placing pan and a washbasin pan for installing a bathtub, and to form an engaging recess that opens upward along one edge of either the bathtub placing pan or the washbasin pan. An engaging piece that is provided and protrudes downward along the other edge is provided, and the engaging piece is inserted into the engaging recess to engage the engaging piece with a waterproof material filled in the engaging recess. A seal is provided between the engaging recesses. With this, the pan can be divided into two pans, the bath pan and the wash pan, to be manufactured in a small size and the manufacturing cost can be reduced, but the engaging piece is engaged with the engaging recess to engage. Since the structure is such that the recess is sealed with the waterproof material that is fully filled and joined together, if the waterproof material is overfilled, the waterproof material may overflow from the upper edges of the rising edges on both sides of the engaging recess. If the waterproof material overflows from the outer rising edge that cannot be seen, there is a problem that the waterproof material cannot be collected, and loss of the waterproof material occurs. There is a problem that water may leak beyond the outer rising edge. The present invention has been made in view of the above points, and it is possible to reduce the size and manufacturing cost as well as to fill the engagement recess without loss of the waterproof material. An object of the present invention is to provide a waterproof floor pan for a bathroom, which can be filled with a waterproof material and can be reliably sealed, and can prevent water from leaking even when the seal is broken.
