DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor pan for a bathroom having a floor pan and a gantry for supporting the pan.

[0002]

2. Description of the Related Art Conventionally, piping work on a floor pan has been carried out by placing the floor pan on a gantry and then diving below the floor pan.

[0003] Therefore, after the positioning of the floor pan is completed, the piping work is performed, and the piping work can be performed without making a mistake in the position of the water distribution pipe.

[0004]

However, in the above-mentioned prior art, there is a problem that the construction is difficult because it sinks below the floor pan.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bathroom floor pan which can easily perform plumbing work.

[0006]

In order to achieve the above object, in a bathroom floor pan according to the present invention, in a bathroom floor pan having a floor pan and a gantry for supporting the pan, the gantry has a pipe-shaped frame. And a water distribution space is provided inside the frame.

[0007] Thereby, piping work can be easily performed. Since the water distribution space is provided inside the frame, piping work performed under the floor pan can be omitted. Once the frame is installed, the plumbing has been completed and it is very convenient.

In the bathroom floor pan, it is preferable that a pipe is provided inside the frame and the inside of the pipe serves as a water distribution space.

In this case, since the pipe has a double structure in which the pipe is provided inside the frame, inspection and maintenance are facilitated. Since water passes through the inside of the pipe, deterioration due to water flow will occur in the pipe. When water leaks due to deterioration of water flow, the pipes may be replaced, which is easier than replacing the entire frame. To replace the entire frame, it is necessary to remove the floor pan, which is very difficult. In addition, the life of the frame can be extended by replacing the tube. This is very convenient for housing equipment requiring a long service life.

The above-mentioned bathroom floor pan has a pipe as a water supply pipe, and this water supply pipe has one set of an in-floor connection port protruding above the floor pan on the outlet side, and an outside-floor connection connected to external piping on the inlet side. Preferably, a plurality of sets of mouths are provided.

In this case, the connection with the external piping can be selected from a plurality of outside floor connection ports. Since a plurality of sets of out-of-floor connection ports are prepared, it is possible to select a convenient one from among them and connect them. The location of the external piping is limited on the architectural design side, and it is unlikely that the location of the external piping will be convenient. Since the bathroom floor pan according to the present invention includes a plurality of sets of out-of-floor connection ports, the out-of-floor connection ports can be selected according to the location of the external piping. This allows
Connection to external piping can be easily performed without making special ones corresponding to the architectural design. Also, it is possible to cope with a sudden change in the location of the external piping at the construction site.

[0012] Preferably, the bathroom floor pan is provided with connection terminals outside the floor at both ends of the frame.

In this case, it is possible to cope with the left and right of the floor pan. By providing the outside-floor connection ports at both ends of the frame, it is possible to cope with the left and right of the floor pan. By providing at both ends of the frame, both the left side of the frame and the right side of the frame can be connected to the external piping, and it can respond to the left and right of the floor pan.

[0014] In the bathroom floor pan, it is preferable that a drain pipe for receiving drainage from the floor pan is provided in the frame, and the drain pipe is disposed immediately below a drain port provided in the floor pan.

In this case, there is no need to separately prepare a drain pipe, and drain pipe work is simplified. Further, the drainage from the drainage port can be directly sent to the drainage pipe. If the drain pipe and the drain port are far apart, it is necessary to connect with a hose or the like, which is troublesome. By providing a drain pipe immediately below the drain port, such trouble can be saved.

In the bathroom floor pan, the drain pipe is preferably formed as a rotatable elbow.

In this case, the drainage direction of the drainage pipe can be adjusted at the construction site, which is very convenient. The location of the external piping for drainage is determined by the architectural design side in the same way as the water supply pipe. If the drain pipe of the bathroom floor pan is rotatable, it can be connected to the external pipe in any direction of 360 degrees, which is very convenient. Also, it can respond to a sudden change in the construction site.
