Abstract

PROBLEM TO BE SOLVED: To easily expand the space in a unit bathroom, by forming an opening at the external wall of a building frame body and projecting a bay window formed on the external wall panel of the unit bathroom, from the opening to the outside of the external wall. SOLUTION: An opening 3 is provided on the external wall 2 of a building frame body 1 and a bay window 4 is fitted to the opening 3 and a part of a bathtub 6 in a unit bathroom 5 is projected to the external wall 2 of the building frame body 1. A decorative frame 4b is widened by aluminum sashes or the like from the external frame 4a so that the bay window 4 is used for the external wall 2 of the building frame body 1 in common and closely stuck on the surface of the external wall 2 to hide repair traces between the opening 3 and the bay window 4. The edge 6a of the bathtub 6 is hooked onto the counter 4c of the bay window 4 to put it close to the external wall as much as possible. And further, a piping unit is arranged at the lower part of the outside of the bay window 4 so that the connection works of all pipes in the bathroom can be carried out through the piping unit.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for expanding a space in a unit bathroom installed in a building body.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional unit bathroom 100 has a floor panel 1 inside a building frame 101. As shown in FIG.
02, since the outer wall panel 103 and the ceiling panel are constructed in a box structure by on-site assembly, the space becomes smaller than the unit bathroom construction space 104 of the building frame 101. Also, when the unit bathroom 100 is installed in contact with the surface of the outer wall 105 of the building frame 101, in most cases, the bathtub 106 is installed so as to be located on the outer wall 105 side, and the bathtub 106 is opened on the outer wall 105 surface. A part 107 is provided and a window 108 and a ventilation fan are attached thereto.

[0003]

As described above, in the conventional unit bathroom, in order to construct the unit bathroom 100 in the building frame 101, the mortar, tiles, etc. are laminated on the surface in the frame 101 to form a bathroom. The space in the bathroom is smaller than that of the construction method. In addition, when the bathroom part is desired to be expanded at the time of renovation, it is impossible unless the outer wall of the bathroom is broken and expanded to the outside, or another room is narrowed.

[0004] However, when the bathroom is expanded outward, there are cases in which a building confirmation application procedure is required in accordance with the provisions of Article 6 of the Building Standards Law accompanying the extension, so various precautions are taken for the expansion of the bathroom. There is a need. An object of the present invention is a construction method capable of easily expanding the space in a unit bathroom,
It is to provide this construction device.

[0005]

The construction method and the construction apparatus according to the present invention proposed to achieve the above object are as follows. 1. A unit bath for extending a bathroom space by the bay window space by forming an opening in the outer wall of the building frame and projecting the bay window formed in the outer wall panel of the unit bathroom from the opening to the outside of the outer wall. How to expand the room. 2. 2. The method for expanding the unit bathroom according to the above item 1, wherein the position of the bathtub in the unit bathroom is protruded to the outer wall of the building frame using the bay window to perform the operation.

[0006] 3. 2. The method of expanding the unit bathroom according to the above item 1, wherein the position of the bathtub in the unit bathroom is partially extended to a position across the base of the building frame using the bay window and constructed. 4. By attaching a decorative frame to the frame of the bay window and covering the opening for mounting the bay window provided on the outer wall with this decorative frame, it is possible to hide repair marks in the gap between the bay window and the outer wall opening and impair the appearance of the outer wall. 4. The method of expanding a unit bathroom according to any one of the above items 1, 2 and 3, wherein the method is performed so as not to be performed.

[0007] 5. 5. The method for expanding a unit bathroom according to any one of the above items 1, 2, 3 and 4, wherein a connection port for various pipes is provided in a portion below the bay window. 6. An outer wall of a building frame having an opening for a bay window, a bay window unit for a unit bathroom constructed so as to protrude from a wall panel through an outer wall surface of the building frame via the opening, and a bay window unit; And a decorative frame formed by enlarging the outer frame so as to be in contact with the outer wall.

[0008]

Since the bay window projects from the unit bathroom through the outer wall of the building frame, the space associated with the bay window is substantially expanded. With the construction of the bay window, the counter can be constructed so as to straddle the outer wall with this bay window, so if this counter is also used as the edge of the bathtub, the bathtub can be protruded to a place very close to the outer wall,
Thus, the floor area on the washing side can be increased.
Further, the floor area of the washing place can be further expanded by projecting the bathtub to a position where a part of the base straddles the bathtub.
By providing a connection port unit such as a gas pipe, a water pipe, and a drain pipe below the outside of the bay window, these piping works can be easily performed.

[0009]

Embodiment 1 In this embodiment, as shown in FIGS. 1 and 2, an opening 3 is provided in an outer wall 2 of a building frame 1, a bay window 4 is attached to the opening 3, and This is an embodiment in which a part of the bathtub 6 is protruded to the outer wall 2 of the building frame 1, and corresponds to claim 1 or 2 or 4 or 5 or 6. The bay window 4 is extended from the outer frame 4a with an aluminum sash or the like so that the bay window 4 also serves as the outer wall 2 of the building frame 1, and is adhered to the surface of the outer wall 2 to repair the gap between the opening 3 and the bay window 4. I try to hide the scars.

The edge 6a of the bath tub 6 is hung on the counter 4c of the bay window 4, so that the bath tub 6 can be placed on the outer wall 2 as much as possible.
So that you can approach the side. In practice, the edge 6a of the bathtub 6 rests on the base 1a. Numeral 8 denotes a piping unit provided at a lower portion outside the bay window 4, and connection work of all the pipes in the bathroom can be performed here, thereby simplifying the work. 9 is a foundation, 10 is a waterproof pan,
11 is a ceiling panel, 12 is a girder.

[0011]

Embodiment 2 In this embodiment, as shown in FIG. 3, when the bay window 4 is constructed, the bathtub 6 is partially protruded to a position over the base 1a. 5, 6, and 7 are supported. In the first and second embodiments, the load of the bay window 4 is the foundation 9 of the building, the pillars, the girders 12, and the like, and is provided on the building frame 1 side.

[0012]

As described above, according to the present invention, a bay window is constructed in a unit bathroom, and a bath tub can be brought close to the window by this bay window, or the bath tub can be partially protruded to the outside of an outer wall. . As a result, the following effects are obtained. 1. The bay space for the bay window is enlarged, and the area of the washing area can be particularly enlarged. For example, in the case of bathroom repair of 3/4 tsubos type,
By projecting the bay window by about 300 mm, it is possible to realize a space almost equivalent to that of the 1-tsubo type. 2. There is no need to change the size of rooms other than the bathroom.

3. Because the bay window has a decorative frame,
There is no need to separately finish the exterior walls. 4. If the bathtub is protruded to the same plane as the outer wall, it is possible to enlarge the washing area by about 200 mm. However, since the floor area of the building does not increase, it is not necessary to apply for confirmation at the time of renovation.

5. If the bathtub is partly protruded above the base and part of the bathtub protrudes outside the outer wall, a confirmation application is required, but it has the merit that the bathroom and washing area can be further expanded. 6. By providing the various pipe connection ports below the bay window, there is an advantage that piping work can be easily performed and water leakage from the connection portion can be eliminated.
