Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of replacing an existing flush-type Japanese-style toilet with a seated toilet, and specifically relates to a method in which a Japanese-style toilet is embedded in a concrete floor.

Conventionally, when replacing this type of Japanese-style toilet with a seated toilet, the opening in the floor was backfilled with mortar after removing the Japanese-style toilet to form a new floor on which to place the seated toilet. Before pouring this mortar, it was necessary to assemble a formwork to close the lower surface of the opening, and the seated toilet could not be installed until the mortar had completely hardened.

Therefore, there were problems in that the replacement work required a considerable amount of time, increased the construction cost, and that the toilet could not be used for several days until the work was completed.

The present invention aims to solve these problems, shorten the construction time, reduce construction costs, and make the toilet usable on the same day.

The basic configuration of the present invention is to remove an existing flush-type Japanese-style toilet from the floor, fix a floor panel to the floor so as to cover the removed opening, and install a seated toilet on the floor panel. This makes it possible to install a seated toilet bowl without backfilling the opening.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The existing flush-type Japanese-style toilet A is well known in this type of technical field, and the one shown has a water supply port a1 at the front of the top and a trap part a at the front of the bottom.
3 and a drain port a2 at the rear of the lower part.The water supply port a1 is connected to a water supply pipe 1 that connects to a water supply device (not shown) such as a flush valve or a tank. and drain part a2
A defecation pipe 2 such as a lead pipe or a vinyl chloride pipe is connected to the pipe.

First, remove the water supply pipe 1 from the water supply port a1 of this Japanese-style toilet A, and install the water supply pipe 1 from the water supply port a1 under the floor or downstairs.
After cutting off the connection between the toilet bowl A and the defecation pipe 2, the Japanese-style toilet bowl A is crushed or otherwise removed from the floor surface D.

Next, the above-mentioned defecation pipe 2 is extended by adding or replacing it midway, and its upper end is raised higher than the floor surface D, and then the floor panel C is attached on the floor surface D.

The floor panel C is made of synthetic resin, FRP, or fire-resistant cement, etc., and has strong and load-bearing properties, and can cover the upper surface of the opening d that will be formed on the floor surface D after the Japanese-style toilet A is removed. Form to size.

In this embodiment, the floor panel C is formed into a flat plate using glass fiber-reinforced cement whose surface is decoratively coated to reduce its thickness and prevent it from easily breaking due to heat or flame.

A through hole c1 is drilled in the center of the floor panel C, through which the upper end of the defecation pipe 2 is inserted, and fixing bolts c2 are screwed in the four corners in the vertical direction, and these fixing bolts c2 are attached to the floor. By screwing into surface D, floor panel C is fixed immovably.

In addition, a hanging wall c3 that fits into the inner circumferential surface of the opening d is protruded in an annular shape on the lower surface of the floor panel C, and between the hanging wall c3 and the inner circumferential surface of the opening d and the lower circumferential edge of the floor panel C. A sealing material 3 such as asphalt or silicone is filled over the entire circumference between and the floor surface D to provide a watertight seal.

On the other hand, the above-mentioned through hole c1 has a drain flange fitting c5 whose inner peripheral surface is inclined in a funnel shape or has a flange part c4 bent diagonally downward toward the center as shown in the drawing, and is fixed to the floor panel C with bolts and nuts c6. do.

After the floor panel C is fixed, the upper end of the defecation pipe 2 that protrudes upward from the through hole c1 of the floor panel C is cut at an appropriate position, and a flange portion is formed at the tip on the inner peripheral surface of the through hole c1. c4, the seat toilet B is installed on the floor panel C and fixed immovably with bolts or the like (not shown), and the drain port b1 of the seat toilet B is connected to the above-mentioned defecation pipe 2. It is fixed to the expanded portion 2' formed at the upper end via a sealing material 4.

At this time, the drainage pipe 2 is prevented from moving in the horizontal direction by the drainage flange fitting c5, and the stool B
Since it is held between the drain flange fittings 5 and prevented from moving in the vertical direction, there is no possibility that the toilet pipe 2 will move due to the drainage force generated when the seated toilet bowl B is flushed, thereby causing water leakage.

Finally, the water supply pipe 1 is connected to the seated toilet bowl B, and the replacement work is completed.

In the above embodiment, the hanging wall c3 was formed on the lower surface of the floor panel C, but the hanging wall c3 may not be formed, and the seated toilet B can be used with feet placed in front or on the side of the front part. Since you will be sitting on toilet B, floor panel C
The shape of the floor panel C is not limited to what is shown in the figure, such as providing a space in front of the floor panel for placing feet.

Furthermore, the drainage flange fitting c5 is the floor panel C.
After fixing it to the floor surface, it was attached to the through hole c1, but it is not limited to this.
can be attached to the floor panel C, or the floor pallet C and the drainage flange fitting c5 may be fixed and integrated.

Since the present invention has the above configuration, it has the following advantages.

After removing the existing flush-type Japanese-style toilet from the floor and fixing a floor panel with a hole through which the defecation pipe is inserted to cover the removed opening, Since the seated toilet is installed in the seated toilet and the defecation pipe is connected to the drain port of the seated toilet, the seated toilet can be installed without backfilling the opening as in the conventional method.

Therefore, construction time can be shortened, construction costs can be reduced, and the toilet can be used on the same day.
