Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to an installation structure for connecting and fixing a drain port provided on the bottom of a sitting toilet bowl to a floor drain with a floor flange.

[Conventional technology]

Stool flush toilets are mainly classified into floor drain type and wall drain type. Among them, the floor drain type has a structure in which a drain outlet 51 is opened on the bottom surface of the toilet body 50 as shown in FIG. 6, and the waste is discharged from the drain outlet 51 to the drain pipe of the building together with washing water. To do. As shown in the figure, the drainage port 51 is provided with a tubular portion 52 protruding downward from the bottom surface of the toilet body 50, which is connected to floor piping.

FIG. 8 is a vertical cross-sectional view of a main part showing a connection structure of the drainage port 51 and the floor pipe. The drainage pipe 53 which is erected under the floor A is connected to the drainage port 51 by the floor flange 1 for connection. ing.
The floor flange 1 is a drain pipe as shown in the plan view of FIG.
A connection port 1a into which the upper end of 53 is fitted is opened, and screw holes 1b for fixing to the floor through fixing screws 2 are provided at four places. The peripheral edge of the connection port 1a is formed as a tapered portion 1c that narrows like a mortar toward the lower end as shown in FIG.
The upper end of 53 is machined on site along the tapered portion 1c. In addition, the toilet body via the floor flange 1 fixed to the floor
Mounting holes 54 for the bolts 3 for mounting the 50 are opened at two places. The mounting hole 54 is formed in a long hole shape so as to run in the circumferential direction of the floor flange 1, and one end side in the long axis direction serves as a bolt insertion portion 55 having a large opening area, and the other end side has an opening area. Form a small bolt engaging portion 56.

On the other hand, the bolt 3 is a so-called T-bolt protruding in a direction in which the head 3a is orthogonal to the shaft portion 3b as shown in FIG. 9, and a male screw is engraved on the peripheral surface of the shaft portion 3b. Then, after fixing the floor flange 1 to the floor A with the fixing screw 2, the head 3a is inserted into the bolt insertion portion 55 of the mounting hole 54,
The shaft portion 3b is moved into the bolt engaging portion 56. This rear shaft
Rotate 3b as it is or rotate it around the axis a little,
The head 3a is set so as to engage with the lower surface of the floor flange 1.

After fixing the floor flange 1 to the floor as described above, the toilet body
The 50 is installed so that its drain port 51 fits into the upper end of the drain pipe 53. At this time, the bolt 3 is passed through the fixing hole 57 formed in the lower surface of the toilet body 50, and the nut 3c is screwed. In addition,
A sealing material 58 is provided between the tubular portion 52 and the floor flange 1 and the drainage pipe 53.

[Problems to be solved by the device]

However, since the mounting hole 54 is long in the circumferential direction of the floor flange 1, the bolt 3 moves in the circumferential direction in the mounting hole 54 with respect to the floor flange 1 fixed to the floor A. Therefore, the floor flange 1
Fixed floor flange 1 when connecting the toilet body 50 to the
On the other hand, the toilet body 50 is in a state of being able to rotate a little around the drainage port 51. This means that when installing the toilet body 50,
This may result in poor connection with the drain pipe 53. For example, as shown in FIG. 8, it suffices that the drain port 51 and the drain pipe 53 are aligned with each other. The surrounding sealing pressure cannot be made uniform, resulting in a defective seal.

There is also a structure in which the floor flange 1 is connected without providing the tapered portion 1c. In this case, it is necessary to scrape off the tubular portion 52 to match the upper surface level of the floor flange 1. However, as shown in FIG. 7, since the tubular portion 52 does not fit into the floor flange 1, when the toilet body 50 is moved, the toilet body 50 is displaced regardless of the position of the floor flange 1. For this reason, the connection is not visible in the actual construction, so the drain 51 and drain 53
There is a risk that water will leak due to defective sealing after installation because the two are connected with their cores misaligned.

Thus, in the case where the bolt 3 is easily displaced from the fixed position with respect to the floor flange 1 or the displacement is too large,
There is a problem in that the connection between the toilet body 50 and the drain pipe 53 is hindered and the number of repairs and the like increases.

The problem to be solved in the present invention is to prevent the fixing bolt from being unnecessarily greatly changed in position with respect to the floor flange, and to ensure the connection between the toilet body and the drain pipe.

[Means for Solving the Problems]

The toilet body is provided with a floor flange for connecting the drainage port of the toilet body to the floor drainage pipe with a sealing structure and for fixing the toilet body to the floor, and the plan shape thereof rises through a mounting hole formed in the floor flange. In a toilet installation structure in which the toilet body is connected and fixed by a T-shaped bolt that engages a substantially rectangular plate-shaped head with the lower surface of the floor flange, the attachment hole allows the long side of the head of the bolt to be inserted. The longer side of the mounting hole has a substantially rectangular opening shape in which the longer side opening edge is made to extend along the circumferential direction of the floor flange and the shorter side opening edge is shorter than the short side length of the head. A notch-shaped escape allowance capable of receiving the shaft portion of the bolt is formed substantially at the center of the opening edge toward the outside from the opening area, and the head is provided when the shaft portion of the bolt is fitted in the escape allowance. In front Wherein the insertable and the it into the mounting hole.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a plan view of a floor flange used in the installation structure of the present invention, FIG. 2 is a sectional view taken along the line II of FIG. 1, and FIG. 3 is a longitudinal section showing a connecting portion between the toilet body and the drain pipe. It is a figure.
For the same members as those shown in the conventional example,
The common reference numerals used in FIGS. 9 to 9 are used for the description, and detailed description thereof will be omitted.

The floor flange 1 is a drainage pipe as in the conventional example shown in FIG.
A connection port 1a into which the upper end of 53 is fitted is opened, and a mortar-shaped tapered portion 1c is formed around it. In addition, fixed seats 1d are formed on the outer periphery at two locations in the radial direction.
A screw hole 1b and a mounting hole 4 are formed in the hole.

FIG. 4 (a) is an enlarged plan view of the fixed seat 1d portion, and FIG. 4 (b).
FIG. 2 is a sectional view taken along line II-II of FIG.

A rim 1e protruding downward is formed on the peripheral portion of the fixed seat 1d. The rim 1e is provided not only on the fixed seat 1d but also on the entire circumference of the floor flange 1, and the height thereof creates a gap between the floor A and the head 3a of the bolt 3 for insertion. Further, the mounting hole 4 is formed as a substantially rectangular plane shape in which the long side is in a posture orthogonal to the radial direction of the floor flange 1. And the opening edge of the outer long side when viewed in the radial direction,
An escape allowance 4a that bulges outward in a circular shape is formed. The clearance 4a is provided so that the head 3a of the bolt 3 can be inserted as shown in FIG. 3 after the floor flange 1 is fixed to the floor A by the fixing screw 2.

FIG. 5 is a perspective view showing how to set the bolt 3 in the mounting hole 4. With respect to the floor flange 1 fixed to the floor A, the bolt 3 has its head 3a facing downward and the shaft portion 3b is inclined outward with respect to the floor flange 1 as shown in FIG. 5 (a). . After that, the head 3a is obliquely inserted from above the mounting hole 4 as shown in FIG. 3B, and the shaft portion 3b is fitted into the clearance 4a. At this time, the head 3a inserted into the mounting hole 4 fits between the lower surface of the floor flange 1 and the floor A at an outer side portion than the shaft portion 3b, and when viewed from above, the inner edge of the head 3a is mounted. It is located inside the opening edge inside the hole 4. This is the opening length of the short side of the mounting hole 4, the size of the head 3a and the clearance.
It can be realized by appropriately setting the dimensional relationship between the outer diameters of 4a and the shaft portion 3b. Next, the shaft 3b is placed in a substantially vertical posture so that the inside of the head 3a is submerged in the mounting hole 4, and as shown in FIG. 5 (c), the entire bolt 3 is placed at the center of the floor flange 1. Move it a little to the side. By such handling, the head 3a comes to engage with the lower surface of the peripheral edge of the mounting hole 4, and the bolt 4 can be set on the floor flange 1.

After the shaft 3b of the bolt 3 is vertically raised and integrated with the floor flange 1 in the manner described above, the fixing hole 57 of the toilet body 50 is aligned with the bolt 3 as shown in FIG. Pass it through the fixing hole 57. Then, by screwing the nut 3c into a male screw formed on the peripheral surface of the shaft portion 3b, the drainage port 51 of the toilet body 50 and the drainage pipe 53 are connected and at the same time the toilet body 50 is fixed to the floor A.
Fixed to. It should be noted that, when connecting the drainage port 51 and the drainage pipe 53, the sealing material 58 is sealed in exactly the same way as in the conventional example.

Here, the mounting hole 4 provided in the floor flange 1 has a shape only provided with a clearance 4a for allowing the head 3a of the bolt 3 to be inserted into the mounting hole 4 so as to allow the shaft portion 3b to escape to the outside. Has become. Therefore, as in the conventional example, the bolt insertion portion 55
And the bolt engaging part 56 are extended in the circumferential direction to extend the mounting hole 4.
The movement of the bolt 3 with respect to the floor flange 1 is less than in the case where the floor flange 1 is opened. This enables the construction in which the toilet body 50 can be fixed at the set position via the floor flange 1 fixed to the drain pipe 53 at a fixed position. That is, the position of the toilet body 1 is determined by the fixing hole 57 and the rising position of the bolt 3, and if the bolt 3 does not deviate from the proper position, the drain outlet 51 can be connected to the drain pipe 53 in the correct posture and positional relationship. Therefore, the drainage port of the toilet body 50
It is possible to perform construction without the core of 51 being displaced with respect to the drain pipe 53, and it is possible to eliminate construction defects such as tilting of the toilet body 50 and the level not matching, and to maintain a good seal.

[Effect of device]

As described above, in the toilet installation structure of the present invention, the mounting hole is opened in the floor flange so that the displacement of the mounting bolt is small, and the drain outlet of the toilet body can be properly connected to the drain pipe. I am trying. Therefore, compared with the conventional shape of the long hole-shaped mounting hole, the displacement of the bolt is suppressed, so that the connection between the drain port of the toilet body and the drain pipe is maintained well and the toilet body can be set to the correct level. At the same time, water leakage due to poor sealing is prevented.
