Abstract

PURPOSE:To shorten the term of construction by installing a wall interval holding fixture on the existing wall section of a prefabricated bath room, and thereby fixedly erecting a new wall section to the wall interval holding fixture. CONSTITUTION:Each wall interval holding fixture 3 composed of a fitting metal in a V-shape, is fixed on an existing wall section 1 with screw 4, and a plane stiffening plate 6 is mounted on the apex 5 of the wall interval holding fixture 3 in parallel with the existing wall section 1. And the outer panel 8 having an opening section 7 in a hook shape to which the upper end of the stiffening plate 6 is inserted, is attached on the outer surface of a new wall section 2. In addition, after the new wall section 2 has been fixedly erected, a ceiling plate which is larger in area than that of a prefabricated bath room, is curved at its center section, so that each end section of it is thereby fixed onto the upper section of the new wall section 2. By this constitution, the term of construction can thereby be shortened to a great extent.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for installing a prefabricated bathroom interior in a bathroom to be renovated.

Conventional technology Generally, when renovating an existing bathroom, the existing walls are removed leaving the floor intact, the foundation is repaired, waterproofing and moisture proofing work is performed, and finishing work is done using mortar, tiles, etc. Therefore, various types of skilled workers are required to carry out renovation work, and the construction period is relatively long (20 days to 1 day).
(months).

Therefore, it is not possible to take a bath during the construction period.

Therefore, in order to shorten the construction period, unit baths and prefabricated prefabricated baths are provided, but unit baths are manufactured to a certain standard size, so they can be used as they are in the existing bathroom. It is impossible to store without it. However, prefabricated baths are created by individually designing a new bathroom to fit within an existing bathroom.
A prefabricated bathroom is produced in a factory based on the design, then delivered to the site in a disassembled state and assembled and constructed in a short period of time (1 to 2 days), which solves the problem of construction time. Recently, the response has been remarkable and the number of orders for its construction is increasing.

Problems to be Solved by the Invention However, when installing the above-mentioned prefab bathroom inside an existing bathroom, the prefab bathroom is disassembled into the bottom of the new floor, the new walls, and the new ceiling, and then transported and handled. The installation of the new floor bottom can be done relatively easily by fitting and fixing the new floor bottom into the existing floor bottom, but the installation of the new wall and new ceiling can be done because there are existing walls and existing ceilings. The task becomes particularly difficult.

Therefore, the purpose of this invention is to provide a construction method that is simple, quick, easy, effective, and highly profitable when installing a prefabricated bathroom inside an existing bathroom for new walls and ceilings. It was done as.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a method for maintaining the wall spacing by attaching a wall spacing holder to the existing wall of the prefabricated bathroom when a prefabricated bathroom is installed inside the bathroom to be renovated. fixing the new wall section upright by locking the new wall section, and after setting and fixing the new wall section upright, curve the ceiling board having an area slightly larger than the ceiling area of the prefabricated bathroom at approximately the center thereof;
The interior installation of a prefabricated bathroom, which consists of fixing the opposite ends of the curved wall to the upper part of the new wall part facing each other, and also having both of these, constitutes a construction method.

Function: According to the above construction method, the new wall section is erected by being locked to the wall spacing holder fixed to the existing wall section, and the new ceiling section is fixed to the top of the new wall section by curving the ceiling board. Installation of new walls and ceilings is extremely simple, as all you have to do is
It's quick and easy.

In addition, since the ceiling board is curved inward, water droplets formed by steam adhering to the ceiling board will flow toward the new wall.
To prevent cold water droplets from dripping onto bathers from the ceiling.

EXAMPLES The present invention will be explained below with reference to the drawings. FIG. 1 is a cross-sectional side view showing an example of construction in which a new wall is erected. In the figure, 1 is an existing wall, 2 is a new wall, and 3 is a wall spacing holder. The wall spacing holder 3 is an eight-shaped metal fitting fixed to the existing wall l with screws 4, 4, and a plate-shaped backing plate 6 is attached to the top 5 in a vertically long manner parallel to the existing wall 1. ing. Then, an outer panel 8 provided with an opening 7 having a hook-shaped cross section into which the upper end of the backing plate 6 is inserted is attached to the outer surface of the new wall 1t (2. When the pillar has a pillar, the pillar and the wall spacing holder may be fixed by providing a member similar to the opening 7 into which the backing plate 6 is inserted. It may be formed over the entire width of the newly installed wall portion 2 or may be formed partially.

Therefore, when installing the new wall part 2, the worker holds the new wall part 2 of a predetermined width with both hands, inserts the opening on the back side into the upper end of the cover plate 6, and then All you have to do is place the parts on the bottom of the newly constructed floor and connect and fix them.

Fig. 2 is a cross-sectional side view showing an example of construction in which a newly constructed ceiling section is installed. It is a beam material. The ceiling board 9 is made of a board whose surface is waterproofed and whose area is slightly larger than the ceiling area of the prefabricated bathroom, and whose approximately central part is made to protrude upward and the whole is curved.
The opposing ends 12, 12 are connected and fixed to the lower edge of the frame 10, which is placed on the upper part of the opposing new wall parts 2, 2 and connected and fixed thereto. Note that instead of the frame 10, it may be connected and fixed to the upper end of the newly installed wall 2.

Any method may be used to connect the ceiling plate 9 and the frame 10. It is preferable that the ceiling board 9 is made up of a single plate as much as possible, but if the ceiling surface of the prefabricated bathroom is large, the only option is to make the ceiling board 9 consist of several pieces, and in that case,
As shown in FIG. 3, if the ceiling surface is rectangular, the short sides thereof are curved, for example, two ceiling panels 9.
9 are arranged adjacent to each other or partially overlapped. Note that the beam material 11 for maintaining the ceiling board 9.9 in a curved state is automatically maintained in a curved state since both opposing ends of the ceiling board 9.9 are connected and fixed to the frame 10. , is not necessarily provided.

Effects of the Invention According to the invention described above, a prefabricated bathroom can be simply, quickly and easily installed inside in one to two days without requiring maintenance of the existing bathroom itself, such as removing existing walls. , the construction period can be significantly shortened, and the situation where it is impossible to take a bath during the construction period can be avoided to the minimum extent possible.
