Description

  The present invention relates to a structure of a wall panel constituting a wall surface of a bathroom.

Conventionally, as shown in FIG. 6, when the wall faucet 2 is attached to the wall panel 1 constituting the wall surface of the unit bath, the rising pipe 4 that is raised from the housing side to the back side of the bathtub 3 or the like. On the other hand, as shown in the longitudinal sectional view of FIG. 7, the flexible pipe 5 is connected on the indoor side, the back wall pipe 6 is connected to the back side of the wall panel 1, and the back wall pipe 6 and the faucet fitting 2 are connected. Connected.
Conventionally, as shown in the partially enlarged view of FIG. 8, since the wall piping 1 is provided so as to protrude further back than the gypsum board 1b on the back side of the wall panel 1, the protrusion D of the wall back is large. Therefore, a considerable space is required behind the wall.

However, recently, in order to increase the internal dimensions of the adjacent room or the unit bath itself, it has become difficult to take a sufficient space behind the wall panel 1.
Therefore, as disclosed in Patent Document 1, the back wall pipe 6 is formed in a flat shape to reduce the protruding dimension D.
JP 2002-106001 A

  However, if the back wall pipe 6 is made flat, it is easy to bend and is likely to be deformed during construction and transportation. Also, if dust enters the back wall pipe 6 for some reason, the pipe itself is easy to flatten. There was a problem of being easily clogged.

The present invention has been devised in view of the above-mentioned conventional problems, and the wall faucet fitting 2 is good even if the projecting dimension from the back of the wall is reduced and the gap between the unit bath and the building frame is narrow. is intended to St. provide wall panels that can be placed in its first aspect, the wall panels constituting the wall surface of the unit bus lined gypsum board is provided on the back surface, both ends through the wall pipe In the back side portion through which the pipe passes, the lining is not provided, but instead a thin plate reinforcement such as a U-shape is provided, the pipe is attached in the thin plate reinforcement, and screw portions provided at both ends of the pipe are provided. It is configured to protrude through the wall .

Further, according to claim 2, in the wall panel constituting the wall surface of the unit bus lined gypsum board is provided on the back surface, the back surface of the portion through which pipe ends through the wall, without providing the backing Instead, a wall-back pipe reinforced with a thin plate reinforcement such as a U-shape is attached , and the screw portions provided at both ends of the wall-back pipe are configured to protrude through the wall. .
A third aspect of the present invention is that the backing is cut out.

In the part where the pipe on the back side of the wall panel passes, a thin plate reinforcement is provided instead of the lining, and the pipe is attached therein so that the screw parts provided at both ends of the pipe protrude through the wall. Because it is configured , the projecting dimension of the back of the wall can be reduced without making the piping flat, etc. Even if the gap between the unit bath and the building frame is narrow, the wall faucet is installed well It will be possible.
In addition, in the wall panel production line, the pipe can be satisfactorily attached to the back of the wall through thin plate reinforcement.

In addition, instead of lining, wall back piping reinforced with thin plate reinforcement such as a U-shape is attached to the part where the piping on the back side of the wall panel passes, and screw parts provided at both ends of the wall back piping by but configured to protrude through the wall, Kabeura pipe is reinforced by the thin plate reinforcement, it is assumed that the strength is secured, the piping assembly line, can be assembled Kabeura pipe and sheet reinforcement Moreover, even if the wall panel is thin, the strength can be secured at the piping portion.
Moreover, the protrusion dimension to a wall back can be suppressed, without changing the diameter of wall back piping.

  Further, since the backing is hollowed out, the wall panel backing can be hollowed out at the time of manufacturing the wall panel or later.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a plan cross-sectional configuration diagram in which a wall panel 1 constituting a wall surface of a bathroom is cut in a horizontal direction, and FIG. 2 is a cross-sectional configuration diagram in a vertical direction. Further, FIG. 3 is a perspective configuration view of the main part of the wall panel as viewed from the back side.

The wall panel 1 is provided with a backing 1b such as a gypsum board on the back side of the surface material 1a inside the bathroom, and a hollow portion 1c that does not have the backing 1b is formed at a predetermined position of the backing 1b. In the portion 1c, a thin plate reinforcement 9 having a U-shaped cross section is bonded and integrated on the back side of the surface material 1a.
The surface material 1a and the thin plate reinforcement 9 are formed with through holes H at the matching positions.

  The connecting screw portion 7a of the lower end L portion 7 provided at the lower end of the back wall pipe 6 is passed through the through hole H from the back side, and as shown in FIG. The flexible pipe 5 can be connected by being fastened to the portion 7 a, and the flexible pipe 5 is connected to the rising pipe 4.

In addition, as shown in the perspective view in FIG. 4 and in FIG. 5, the cross section along line AA in FIG. 4, the back wall pipe 6 can be attached in the U-shaped thin plate reinforcement 9. The lower end L portion 7 at the lower end of the back pipe 6 and the upper end L portion 10 at the upper end can be attached in advance by projecting only the connecting screw portions 7a and 10a on the front surface of the thin plate reinforcement 9, respectively.
In this way, in the pipe assembly line of the back wall pipe 6, the back wall pipe 6 is assembled in advance in the thin plate reinforcement 9 to ensure the strength of the back wall pipe 6 itself, and carried into the site in such a state. Then, the thin plate reinforcement 9 can be adhered and fitted into the cut-out portion 1 c of the wall panel 1 and integrated with the wall panel 1.

It is to be noted that a cut-out portion 1c is formed on the back side of the wall panel 1 at the site, and a thin plate reinforcement 9 is attached, and the back wall pipe 6 can be attached in the thin plate reinforcement 9, and the wall panel 1 is preliminarily installed in the factory. In the state where the thin plate reinforcement 9 and the back wall pipe 6 are attached to the cut-out part 1c on the back side of the steel sheet, it can be transported to the site.
The cut-out portion 1c may be formed by cutting the backing 1b over the entire back surface of the surface material 1a, and then cutting out the portion of the cut-out portion 1c when the backing 1b is attached to the surface material 1a. It may be any of those formed by sticking the backing 1b.

  In this example, since the back wall pipe 6 is mounted in the thin plate reinforcement 9 having a U-shaped cross section, the protrusion dimension D ′ to the back wall is smaller than the conventional size. Without using a flat shape or the like as in the prior art, a perfect circular wall pipe 6 can be used, and even when the back surface of the wall panel 1 constituting the wall surface of the unit bath and the gap between the building frame are narrow, It is possible to provide the wall back pipe 6 well and install the faucet fitting 2 on the indoor side.

It is a plane cross-section block diagram of the state which attached thin plate reinforcement to the back side of a wall panel, and also attached wall back piping in this thin plate reinforcement. It is a longitudinal section lineblock diagram of the state where wall back piping was attached. It is the perspective block diagram seen from the back side of the wall panel. It is the perspective block diagram which attached and integrated wall back piping in the thin plate reinforcement previously. It is the sectional view on the AA line of FIG. It is a perspective block diagram of the state which installed the faucet metal fitting in the wall panel of the bathroom. It is a longitudinal cross-sectional block diagram of the conventional piping structure which shows the attachment state of a faucet metal fitting. It is an enlarged block diagram of the principal part of FIG.
