Description

  The present invention relates to a partition wall structure and a reforming method for a sanitary room, and more particularly, a partition wall structure and a reforming room for a sanitary room suitable for changing the size of a unit bath or the floor area of a dressing room to a size different from that before the reform. Regarding the method.

  When remodeling an aged unit bath, there is a need to change the size of the unit bath to a size different from that before the remodeling. Normally, when making a new unit bath larger than the old unit bath, the old partition wall that separates the bathroom and the dressing room is removed, and some of the skeleton walls and ceiling panels around the partition wall are also removed. Install a unit bath. Therefore, after that, in addition to the work of installing the new partition wall, the work of restoring the skeleton wall and ceiling plate is required. Restoration work includes reworking gypsum board, wallpaper, cloth, etc. Such work requires materials and time, and is expensive. On the other hand, when only the sanitary room of a building is partially remodeled, the work is often done in the presence of residents, and it is desirable to shorten the construction period.

  In Patent Document 1, the bathroom is expanded by inserting a part of the bathtub of the bathroom into a partition space on the base between the bathroom and the dressing room.

Japanese Unexamined Patent Publication No. 3491611

In Patent Document 1, the bathtub size of the bathroom can be expanded, but the washroom size cannot be expanded.
In view of the above circumstances, the present invention changes the size of the unit bath including the bathtub and the washing room of the bathroom and the floor area of the dressing room to a size different from that before the reform while substantially leaving the body wall and ceiling plate of the sanitary room. An object of the present invention is to provide a partition wall structure and a reforming method that can be performed, can shorten the construction period, and can reduce the construction cost.

In order to solve the above problems, the structure of the present invention is a partition wall structure including a partition wall that partitions a bathroom and a changing room of a sanitary room,
The partition wall includes a partition unit having a door frame, and a hanging wall provided on the upper side of the partition unit, and an upper end portion of the hanging wall has an overhead ceiling via a connecting crosspiece provided on a ceiling surface. It is characterized by being supported by the ceiling joists.

  According to the partition wall structure, by supporting the upper end portion of the partition wall to the ceiling joist via the connecting crosspiece, it is possible to reduce the required connection strength between the side portion of the partition wall and the body wall. Further, since the connecting crosspiece may be provided on the ceiling surface, that is, the lower surface of the ceiling plate, it is not necessary to remove the ceiling plate. Therefore, the frame wall and the ceiling plate can be left without breaking them. In addition, the installation position of the partition wall can be easily adapted to the size of the new unit bath by adjusting the position and the length of the connecting beam. Therefore, the size of the unit bath and the floor area of the dressing room can be changed to a size different from that before the reform, the construction period can be shortened, and the construction cost can be reduced.

The superposed material has a superposed portion extending vertically and a unit side fixing portion provided on a side portion of the superposed portion on the unit body side, and the unit side fixing portion is joined to the unit main body It is preferable that the overlapping portion overlaps with the gap adjusting portion.
By adjusting the overlapping width of the gap adjusting material and the overlapping material, the width of the partition wall can be adapted to the width of the sanitary room. It can also accommodate sanitary rooms of different widths.

A cushioning material is preferably interposed between the overlapping portion and the wall-side fixing portion.
With the cushioning material, it is possible to keep the gap between the overlapping portion and the gap adjusting portion substantially free from each other. In addition, it is possible to reduce the impact when the door is opened and closed.

Here, when the width of the dressing room is narrow, it may be difficult to secure a flow line from the dressing room to the bathroom if an attempt is made to secure a space for disposing the vanity and the washing machine storage space. It may be possible to secure the flow line by reducing the storage space and changing the layout of the vanity and the washing machine storage space, but it is inconvenient if the storage space in the dressing room is small or small.
In view of such circumstances, it is preferable that a storage shelf is provided on the partition wall.
As a result, the partition wall structure can be used to maximize the space in the dressing room. That is, even if the dressing room is narrow, the vanity and the washing machine storage space can be arranged so as to secure the flow line for entering and leaving the bathroom, and the storage space can be secured.

It is preferable that the storage rack is arranged at an intermediate height of the partition wall.
As a result, an arrangement space such as a laundry water supply unit can be set below the storage rack.
