The fixture 50 is fixed to the floor surface 100 and fixes the inflow port 31 (inflow pipe portion 36 ) to the position of the drain port 16 of the toilet body 10 . The fixture 50 is open upwardly, downwardly, forwardly and rearwardly for the drainage socket 30 to pass through. The fixture 50 includes a socket fixing portion 51 for fixing the drainage socket 30 , a leg portion 52 for supporting the socket fixing portion 51 , and a fixed portion 53 fixed to the floor surface 100 .

The socket fixing portion 51 integrally includes a plate-like portion 57 having a substantially rectangular flat plate shape in plan view, and a tubular portion 54 provided substantially at the center of the plate-like portion 57 and having openings on both sides in the vertical direction. I have. When the fixture 50 is fixed to the floor surface 100, the plate-like portion 57 is arranged substantially parallel to the floor surface 100 at a predetermined height position, and the cylindrical portion 54 opens vertically upward.

The tubular portion 54 protrudes from both the upper and lower sides of the plate portion 57 . A portion of the cylindrical portion 54 that protrudes upward from the plate-like portion 57 is a toilet connecting portion 54B to which the drain port 16 of the toilet body 10 is connected.

A packing 60 made of an elastic material is attached to the toilet connection portion 54B. A locking projection 55 for locking the packing 60 in the axial direction is provided on the outer peripheral surface of the toilet bowl connection portion 54B. The packing 60 has an annular outer fitting portion 61 fitted to the outer peripheral side of the toilet connecting portion 54B, and an extension portion 62 extending to the inner peripheral side of the toilet connecting portion 54B.

The fastening member 56 is fixed to the floor surface 100 at four locations (four corners) around the cylindrical portion 54 substantially at the center.

Next, an example of a construction method for the flush toilet T of this embodiment will be described. The drain connector C of the flush toilet T is composed of an underfloor drainage system (see FIG. 1) for draining sewage to a drain pipe 101 provided on the floor of the toilet body 10, and a drain pipe 102 provided on the wall of the toilet room. It can be used with both the floor drainage system (see Fig. 5) that drains wastewater directly into the system.

The construction method of the flush toilet T consists of a drain pipe connecting step of connecting the outlet port 32 of the drain socket 30 to the floor drain pipe 101 or the wall drain pipe 102, and aligning the inlet port 31 of the drain socket 30 to a predetermined position. and a toilet connection step of connecting the drain port 16 of the toilet bowl body 10 to the drain port 31 of the drain socket 30 . The toilet connection step is performed after the drain pipe connection step and the inlet fixing step.

Either the drain pipe connecting step or the inflow port fixing step may be performed first. That is, after connecting the outlet port 32 of the drain socket 30 to the floor drain pipe 101 or the wall drain pipe 102, the inlet port 31 of the drain socket 30 may be fixed by the fixture 50, or the drain socket 30 may be The outlet 32 of the drain socket 30 may be connected to the floor drain 101 or the wall drain 102 after the inlet 31 is secured by the fixture 50 .

In the drain pipe connecting process or the inlet fixing process, the position of the inlet 31 and the outlet 16 of the toilet body 10, and the position of the outlet 32 and the floor drain pipe 101 or the wall drain pipe 102 are aligned with each other. The drainage socket 30 is modified. For example, in construction of the underfloor drainage system, as shown in FIG. 1, the middle part of the drainage socket 30 can be deformed into a stepped shape, and in construction of the above floor drainage system, as shown in FIG. The intermediate portion of 30 can be bent substantially at a right angle.

In the inflow port fixing step, a floor fixing work of fixing the fixture 50 to the floor surface 100 and a socket fixing work of fixing the drain socket 30 to the fixture 50 are performed. Either the floor fixing work or the socket fixing work may be performed first. That is, after fixing the fixture 50 to the floor surface 100 , the drainage socket 30 may be fixed to the fixture 50 , or after fixing the drainage socket 30 to the fixture 50 , the fixture 50 may be fixed to the floor surface 100 . You may

In this way, after the drain pipe connecting step and the inlet fixing step, the toilet bowl connecting step is performed. In the toilet connecting step, the drain port 16 of the toilet body 10 is connected to the inlet 31 of the drain socket 30 fixed at a predetermined position by the fixture 50 . The inflow port 31 of the drain socket 30 is aligned with the drain port 16 of the toilet body 10 in both the height direction and the horizontal direction, and opens vertically upward.

The toilet bowl body 10 is lifted, the drainage projecting pipe part 17 is aligned with the toilet bowl connection part 54B of the fixture 50, and the toilet bowl body 10 is lowered onto the floor surface 100 so as to cover the drainage socket 30. - 特許庁The drainage protruding pipe portion 17 of the toilet body 10 is inserted into the toilet bowl connecting portion 54B, and the extending portion 62 of the packing 60 is brought into close contact with the outer peripheral surface of the drain protruding pipe portion 17 and the inner peripheral surface of the toilet bowl connecting portion 54B. , the cylindrical portion 54 and the drainage projecting pipe portion 17 are connected. As a result, the drainage projection pipe portion 17 and the inflow pipe portion 36 are connected in the axial direction, and the drainage port 16 and the inflow port 31 are communicated with each other. Also, the drain socket 30 fits inside the skirt portion 18 .
By the above, the installation work of the flush toilet T is completed.
