DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a bathroom ceiling.

[0002]

2. Description of the Related Art Conventionally, bathrooms have been installed in houses and the like. As shown in FIG. 8, the bathroom 1 has a waterproof pan 2 having a washing area, a bathtub 3 integrated with or separate from the waterproof pan 2, and standing upright on the periphery of the waterproof pan 2 and the bathtub 3. A wall panel 4 which surrounds the periphery of the waterproof pan 2 and the bathtub 3;
And a ceiling panel 5 which covers a rectangular upper opening formed by the above.

[0003] The bathroom 1 is usually assembled by a panel construction method in which a waterproof pan 2 is installed, and a wall panel 4 is fixed with screws from the outside of the bathroom 1.

[0004] The wall panel 4 includes a surface material 41 such as a calcium silicate plate, a backing material 42 such as a gypsum board adhered to the back surface of the surface material 41, and a cross section fixed to the back surface periphery of the surface material 41. The upper reinforcing frame 43 of the reinforcing frame 43 has a locking protrusion 431 having a locking portion 431a, and is formed to protrude upward (see FIG. 9).

The ceiling panel 5 is made of a PVC steel plate 51,
A backing material 52 such as a gypsum board adhered to the back surface of the PVC steel plate 51, and a fitting portion 511 having a U-shaped cross section that opens downward is folded at the outer peripheral edge of the PVC steel plate 51. The song is formed. A plurality of ceiling connecting members 6 made of plastic, for example, hard vinyl chloride are fitted at appropriate intervals to the fitting portion 511 of the PVC steel plate 51 of the ceiling panel 5. The ceiling connecting member 6 is formed in a shape substantially matching the fitting portion 511 of the ceiling panel 5, has a hollow portion 61 therein, and has the hollow portion 6.
A pair of holding portions 62 protruding inward are formed at one inlet (see FIG. 9).

The upper reinforcing frame 43 of the wall panel 4
A backup material S1 is disposed on the upper surface of the PDP. A PVC steel plate 51 of the ceiling panel 5 is placed on the backup material S1 in close contact with the backup material S1.

The butting portion between the wall panel 4 and the ceiling panel 5 is filled with a silicon caulking material S2.

Therefore, in order to attach the ceiling panel 5, the ceiling connection member 6 is fitted to the fitting portion 511 of the PVC steel plate 51 of the ceiling panel 5, and then the ceiling panel 5 is sucked by a suction cup (not shown) to form the wall panel 4. Lift up. When the ceiling connecting member 6 provided on the ceiling panel 5 is opposed to the locking projection 431 of the wall panel 4 and the ceiling panel 5 is dropped by lowering the suction cup, the locking projection 43 of the wall panel 4 is lowered.
The first locking portion 431a enters the hollow portion 61 of the ceiling connection member 6, and at this time, the pair of holding portions 62 hold the locking projection 431. As a result, the ceiling panel 5 is prevented from separating from the wall panel 4 (for example, see Japanese Patent Application Laid-Open No. 10-1).
No. 69219).

By the way, the ceiling panel 5 of the bathroom 1 described above.
Since the is formed in a flat plate shape, the design is poor, and if the ceiling is low, the bather may feel a feeling of oppression.

Therefore, in recent years, the ceiling panel 5 of the bathroom 1 has been
Proposing a curved shape that protrudes toward the back of the ceiling, such as a dome shape, arch shape, or shell shape, enhances the design and proposes to make the ceiling surface look higher so that it does not suffer from oppression. (See, for example, Japanese Utility Model Registration No. 2516502).

[0011]

However, since the curved ceiling panel 5 cannot be sucked by the suction cup, the curved ceiling panel 5 is dropped and the ceiling connecting member 6 is engaged with the locking projection 431 of the wall panel 4. There is a problem that it cannot be fitted into the device.

In this case, an inspection opening is formed in the curved ceiling panel 5, the body leans out from the inspection opening, the outer peripheral edge is pushed in, and the ceiling connecting member 6 is fitted into the locking projection 431 of the wall panel 4. Although it is conceivable, the appearance of the curved ceiling panel 5 is impaired by forming the inspection port, and the interval between the skeleton side ceiling and the curved ceiling panel 5 which is convex toward the ceiling backside is narrowed. Ceiling panel 5
In some cases, it is not possible to secure a space on the back side of the vehicle for a worker to lean on. Further, even if the user can lean into the narrow space behind the ceiling from the inspection opening, the workability is reduced, and the working radius is larger than that of the flat ceiling panel 5, and the outer peripheral edge of the curved ceiling panel 5 The operator cannot reach the edge, and the work of fitting the ceiling connection member 6 cannot be performed.
