DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 to 5, A is a floor flange of the present invention, and more specifically, a floor flange for fixing a sanitary fixture (a stool type toilet is shown in the drawing) B to an installation floor F as shown in FIG. The connecting pipe 1 includes a tubular connecting pipe 1 connected to an open end C1 of the pipe C, and an annular flange 2 extending substantially horizontally outward continuously to an upper opening edge of the connecting pipe 1.

An annular locking edge 2a surrounding the drain port B1 of the sanitary ware B is formed on the upper surface side of the flange portion 2, and a sealing material 10 described later is filled outside the locking edge 2a. An annular concave portion 2b is formed. In addition, the floor flange A is installed on the outer periphery of the flange portion 2 on the floor surface F.
Hole 3a through which a wood screw 11 or the like is inserted for fixing
The left and right fixing portions 3 having the shape are extended like ear pieces.

The fixing portions 3 are provided symmetrically on the outer periphery of the flange portion 2, and the through holes 3 a are provided at appropriate positions of the respective fixing portions 3. Further, a bolt insertion hole 4 for inserting a mounting bolt 12 for fixing the sanitary fitting B to the floor flange A is formed in each fixing portion 3 separately from the through hole 3a. The bolt insertion hole 4 is
Can not be inserted, but the threaded rod portion 12b
It is formed in the shape of a long hole having a width enough to insert
It extends along the circumferential direction of the flange portion 2. At the end of the bolt insertion hole 4, an opening 5 having a size enough to insert the seat plate 12 a is formed continuously with the bolt insertion hole 4.

On the back surface of the fixing portion 3, a concave portion 6 located below the bolt insertion hole 4 and the opening 5 is formed. The recess 6 is provided between the floor flange A and the installation floor surface F when the floor flange A is installed.
2a can be stored.

Thus, the present invention is characterized in that a stopper piece 7 is provided between each bolt insertion hole 4 and the opening 5 in the floor flange A having such a structure. As shown in an enlarged manner in FIGS. 2 and 3, the stopper piece 7 projects slightly downward at the lower surface of the opening edge 5a of the opening 5 on the bolt insertion hole 4 side. Between the mounting floor 12 and the floor 1
Bolts are provided on the left and right sides of the bolt insertion hole 4 with a dimension capable of forming a gap s through which the bolt 2a can be inserted.

In the drawings, reference numerals 8a and 8b denote floor flanges A at predetermined positions indicated by cross-shaped score lines G drawn on the installation floor F.
It is an alignment mark for setting up.

Hereinafter, the procedure for installing the sanitary ware B using the floor flange A of the present embodiment having the above configuration will be described.
This will be described with reference to FIG. First, as in the case of the conventional floor flange, the connecting pipe 1 is inserted into the opening end C1 of the drain pipe C piped below the installation floor F to connect the connecting pipe 1 to the drain pipe C. The flanges 2 are fixed to the installation floor F with the wood screws 11 with the 8a and 8b positioned on the score line G. Next, an annular seal member 10 having a U-shaped cross section is disposed in the concave portion 2b on the upper surface of the flange portion 2, and a foam packing 13 is disposed above the seal member 10. Further seat plate 1
After the screw 2a is inserted into the opening 5, the screw rod 12b is inserted into the bolt insertion hole 4 and the mounting bolt 12 is mounted, and the mounting bolt 12 is raised at a predetermined position. Of the mounting bolt 12 is not prevented by the stopper piece 7.

The sanitary fixture B is set by inserting the threaded rod portion 12b of the mounting bolt 12 into the bolt hole B3 provided in the pedestal portion B2 of the sanitary fixture B, and the nut 14 is screwed from the upper surface of the pedestal portion B2. The sanitary fitting B is temporarily fixed so as to be rotatable. At this time, as the screw rod portion 12b is screwed upward, the seat plate 12a is raised to a position where it can abut against the stopper piece 7. At the same time, the sealing material 10 is crushed by the back surface of the pedestal portion B2 and the concave portion 2b of the flange portion 2 to seal the connection portion. Locking edge 2a so as not to slip off from tube C
Regulates its position. The foam packing 13 is formed in a thin ring shape using a desired foam material, and is previously fixed to the back surface of the pedestal portion B2 with an adhesive or the like to absorb irregularities on the back surface of the pedestal portion B2, and A gap is prevented from being formed between the sealing member 10 and the sealing member 10. Finally, the nut 14 loosely fitted to the mounting bolt 12 is tightened to fix the sanitary ware B. In the temporary fixing state, for example, when the flange portion 2 is not installed at a predetermined position and the installation position (angle) of the sanitary ware B is shifted,
The sanitary fitting B is rotated to slide the mounting bolt 12 in the bolt insertion hole 4, whereby the sanitary fitting B is rotationally adjusted so as to be arranged according to the initially set layout.
At this time, the seat plate 12a collides with the stopper piece 7 to prevent the mounting bolt 12 from dropping to the opening 5 side. Then, after the adjustment, the nut 14 is tightened to fix the sanitary ware B.

Although the sanitary ware B is a toilet in the drawings, the floor flange of the present invention is not limited to a toilet.
It is used for fixing urinals and various other sanitary appliances. Further, in the above-described embodiment, the connecting pipe portion 1 of the floor flange A is formed in a cylindrical shape, but may be formed in a funnel shape as shown in FIG.
