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 created on the ground surface where the Japanese-style toilet was removed was backfilled with mortar to form a new floor surface on which to place the seated toilet. Before pouring the tar into this mortar-1-, it is necessary to assemble a formwork to close the lower surface of the opening, and a seated toilet cannot be installed until the mortar has completely hardened.

Therefore, there were problems in that the replacement work required a considerable amount of time, which increased the cost of the work, 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 structure of the present invention is to remove the existing flush-type Japanese-style toilet from the floor, fix a floor panel to the floor so as to cover the opening after removal, 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.

2- The existing flush-type Japanese style toilet (A>) is well known in the field of this type of toilet, and the one shown has a water supply port (
al), a trap part (C3) is formed at the front of the lower part, and a drain port (C2) is formed at the rear of the lower part.The water supply port (al) is equipped with a flush valve, tank, etc. A water supply pipe (1) is connected to a water supply system @ (not shown), and a drainage pipe (2) such as a lead pipe or a vinyl chloride pipe is connected to the drain port (C2).

First, remove the water supply pipe (1) from the water supply port (al) of this Japanese-style toilet (A), and install the water supply pipe (1) from the water supply port (al) under the floor or downstairs.
) and the defecation pipe (2), and then crush the Japanese-style toilet (A) and remove it from the floor (F)).

Next, extend the defecation pipe (2) by adding it in the middle or replacing it in the middle to raise its upper end higher than the floor (D), and then install the floor panel (D) on the floor (D).
Install C).

The floor panel (C) is made of synthetic resin, FRP, or fire-resistant material such as cement, which has strong toughness and load-bearing properties, and is installed on the floor surface (D) after removing the Japanese-style toilet (A). It is formed to a size that can cover the upper surface of the opening (d).

In this example, the surface of the floor panel (C) is
It is molded into a flat plate using painted glass fiber reinforced cement to reduce its wall thickness and prevent it from easily breaking due to heat or fire.

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 into the four corners in the vertical direction. By screwing these fixing bolts (C2) into the floor surface (D), the floor panel (C) is fixed immovably.

Further, on the lower surface of the floor panel (C), a hanging wall (C3) that fits into the inner circumferential surface of the opening (d) is protruded in an annular shape, and the hanging wall (C3) and the inner circumferential surface of the opening (d) are provided. and the floor panel (
A sealing material (3) such as asphalt or silicone is filled between the lower peripheral edge of C) and the floor surface (D) over the entire circumference to provide a watertight seal.

4- On the other hand, the through hole (C1) has a drain flange fitting (C5) whose inner circumferential surface is inclined in a funnel shape or has a flange portion (C4) bent diagonally downward toward the center as shown in the drawing.
) to the floor panel (C) with bolts and nuts (C6).

After fixing the floor panel (C), cut the upper end of the defecation pipe (2) that protrudes upward from the through hole (C1) of the floor panel (C) at an appropriate position, and ) after expanding along the flange part (C4) formed on the inner circumferential surface of
A seat toilet (B) is installed on the floor panel (C) and fixed immovably with bolts (not shown), and the drain port (bl) of the seat toilet (B) is connected to the defecation pipe (2). It is fixed to the widening part (2') formed at the upper end of the housing via a sealing material (4).

At this time, the drainage pipe (2) is prevented from moving in the horizontal direction by the drain flange fitting (C5), and is also sandwiched between the seated toilet bowl (B) and the drain flange fitting (5), preventing it from moving in the vertical direction. Therefore, water leakage will not occur due to movement of the defecation pipe (2) due to the drainage force generated when flushing the seated toilet bowl (B).

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

In the front claw embodiment, the hanging wall (C3) was formed on the lower surface of the floor panel (C), but it is not necessary to form the hanging wall (C3), and the seated toilet (B) is placed in front of or in front of the hanging wall (C3). Since you sit on the toilet bowl (B) with your feet on the sides of the floor panel (C), make sure to provide space for your feet in front of the floor panel (C).
The shape of is not limited to that shown in the figure.

Furthermore, the drainage flange fitting (C5) is attached to the floor panel (C).
Although the drain flange fitting (C5) can be attached to the floor panel (C) in advance, the drain flange fitting (C5) can be attached to the floor panel (C) in advance.
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 frontage after removal, the floor Since the seated toilet is installed on the panel 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 past.

Therefore, (1) it is possible to shorten the work time and reduce construction costs, and also to make the toilet ready for use on the same day.
