Description

Prefabricated Bathroom with the Integrated Polyurethane Wall}

The present invention relates to a prefabricated bathroom using an integral wall, and more particularly, an electric wire, an outlet, a hot water pipe, and a cold water pipe are embedded in a polyurethane layer surrounded by a frame, a polyurethane layer tile and a ceiling panel upper groove, and polyurethane. A prefabricated bathroom using a polyurethane integral wall of wood panels and gypsum board on the other side of the floor.

The prior art of such a prefabricated bathroom is a "prefabricated bathroom using an integral wall" which the applicant has filed in 1999 patent application No. 10,991.

1 is a cross-sectional view of a unitary wall of a conventional prefabricated bathroom, in which a lightweight composite panel composed of foamed polystyrene cement board 41 and non-asbestos cement boards 42 and 43 on both sides of foam polystyrene cement board 41 in the middle thereof. In the foamed polystyrene cement board 41, an electric wire, a pipe 44, and the like are embedded, and a tile 45 is attached to one non-asbestos cement board 43, and a ceiling panel upper groove 46 for mounting a ceiling panel is provided. The integral wall 40 is formed.

FIG. 2 is a view illustrating the installation of a prefabricated bathroom using such a conventional integrated wall. After the floor slab 1 and the ceiling slab 2 are completed, the waterproof plate frame 20 is placed on the floor slab 1 of the building. After installing the piping or the like on the waterproof plate 30, the watertight plate 30 on which the pipe is installed is placed on the waterproof plate frame 20, and then an integral wall 40 is formed on the four edges of the waterproof plate 30. And fix the unitary wall 40 to the waterproof plate frame 20 with the lower bracket 52 and fix the unitary wall 40 to the ceiling slab 2 with the upper bracket 51 and then install the unitary wall ( After assembling the bracket 53 to the ceiling panel upper groove 46 of 40), the ceiling panel 50 is placed in the groove 46 to which the bracket 53 is assembled, and then the outer surface of the unitary wall 40 is mounted. In other words, the prefabricated bathroom 10 is completed by applying a wallpaper or paint to the bathroom wall facing the living room or the room.

This conventional prefabricated bathroom 10 has the advantage of not requiring a separate masonry wall by using an integral wall 40, while the integral wall 40 has one foamed polystyrene cement board 41. ) And two non-asbestos cement boards 42 and 43, which has a heavy disadvantage and also takes a week to harden the cement and takes a lot of time and is difficult to manufacture.

Accordingly, in the present invention, in order to solve the problem of the prefabricated bathroom using the conventional integrated wall as described above, the electric wire, outlet, hot water pipe and cold water pipe are embedded and surrounded by a frame polyurethane frame, polyurethane layer tile and ceiling on one side It is intended to provide a prefabricated bathroom using a polyurethane integral wall made of wood paneling and gypsum board on the other side of the paneling groove, the polyurethane layer.

The polyurethane integral wall of the present invention is composed of tiles, polyurethane layers, wood paneling and gypsum board, which is light in weight and does not take time to manufacture because cement is not used, and is easy to manufacture. Solve it.
