Description

  The present invention relates to a floor flange for fixing a drain socket to a floor surface.

  In general, the drainage port of the flush toilet and the drain pipe provided on the floor are connected via a drain socket (see Patent Document 1). Therefore, when an existing flush toilet is removed and another flush toilet is attached, the drain socket connecting the flush toilet and the drain pipe may be replaced. In addition, there are cases where drainage pipes, wiring for underfloor heating, and the like are embedded in the floor surface of the toilet room.

JP-A-9-291582

  Since the drain socket is fixed to the floor with screws, if the location of the existing drain socket's floor fixing screw hole is different from that of the new drain socket's floor fixing screw hole, it will be different from the existing screw hole. In some cases, a new screw hole was opened at the position.

  At this time, if the screw hole position of the new drain socket overlaps with the position of the wiring for underfloor heating, opening the new screw hole may damage the drain pipe or the wiring for underfloor heating. It was.

  The present invention has been made in view of such problems, and its purpose is to reuse the existing screw holes provided in the floor surface when replacing the drain socket, and thereby to the floor surface. To provide a floor flange capable of fixing a drain socket without providing a new screw hole.

  In order to solve the above-mentioned problem, the first aspect is a floor flange that is screwed to the floor surface where the end of the drain pipe is exposed, and that fixes the drain socket connected to the drain pipe to the floor surface, An opening through which the drainage pipe is inserted, and a flange portion having an upper end surface formed on the opposite side of the installation surface and the installation surface to be installed on the floor surface around the opening, and the flange portion And a mark flange formed in at least three directions from the opening.

When replacing the existing drainage socket with a new drainage socket using the floor flange having such a configuration, first, the position of the screw hole of the existing drainage socket removed from the floor surface is transferred to the floor flange.
In the drain socket, in order to make the center of the drain pipe connection portion of the drain socket coincide with the center of the drain pipe, position adjustment marks are provided on the side surfaces of the drain socket in at least three directions from the center of the drain pipe connection portion. Therefore, when transferring the position of the screw hole of the existing drain socket to the floor flange, the floor is formed by the mark portion formed on the flange portion and the position adjustment mark formed on the drain socket. The position of the existing drain socket with respect to the flange is aligned and the position of the screw hole is transferred.
Next, the position of the screw hole of the new drain socket is transferred to the floor flange. Also at this time, transfer is performed in a state where the position of the existing drainage socket with respect to the floor flange is aligned by the mark portion formed on the flange portion and the position adjustment mark formed on the drainage socket. By doing in this way, the position of the screw hole of the existing drain socket and the position of the screw hole of the new drain socket are transferred to the floor flange.
The existing drainage socket and the new drainage socket are transferred to the floor flange by marks formed in at least three directions from the opening. The front and rear, left and right positions of the drainage core can be matched with the mounting angle of the drainage socket. Thereby, when a new drain socket is attached via the floor flange, it is possible to prevent the drain core of the new drain socket from shifting from the drain core of the drain pipe or from the mounting direction of the existing drain socket.
And when fixing a new drain socket to the floor surface through this floor flange, for example, the floor surface in a state where the installation surface of the floor flange is directed to the floor surface using the position of the screw hole of the existing drain socket. The new drain socket is fixed to the upper end surface of the floor flange by using the position of the screw hole of the new drain socket transferred to the floor flange. Thereby, since a floor flange is fixed to a floor surface using the position of the screw hole of the existing drain socket, the existing screw hole provided in the floor surface can be reused. Therefore, a new drain socket can be fixed without providing a new screw hole on the floor surface.

  Moreover, a 2nd aspect is a 1st aspect. WHEREIN: The said flange part has an intermediate surface formed between the said installation surface and the said upper end surface, and the said intermediate surface makes the said flange part a floor surface. It is a floor flange spaced apart from the floor surface when installed on the floor.

In general, the gap between the drain pipe and the floor is closed by mortar or the like. Therefore, the mortar may be raised around the drain pipe. In addition to the rise of mortar, there may be some unevenness (unevenness) on the floor. If a drain socket or a toilet bowl is fixed to the floor on which the unevenness is formed, the floor flange may be deformed by the unevenness.
According to such a configuration, there is a space between the floor surface and the flange portion around the opening of the flange portion by the intermediate surface that is spaced and opposed to the floor surface when the flange portion is installed on the floor surface. Is formed. Therefore, this space makes it difficult for the unevenness formed around the flange portion and the drain pipe to come into contact. Therefore, it can suppress that a floor flange deform | transforms by contacting a floor flange to the non-land.

  In addition, in the first aspect or the second aspect, a third aspect is that when the center point of the opening is a vertex, an angle formed by the mark parts adjacent to each other is different from that of the other mark parts adjacent to each other. The floor flange is equal to the angle formed.

According to such a configuration, the angle formed by the mark portions adjacent to each other is equal to the angle formed by the other mark portions adjacent to each other. Therefore, the mark portion formed on the flange portion is based on the center point of the opening. On the circumference, the angles between a plurality of adjacent mark portions are all made equal.
Therefore, when aligning the drain socket with respect to the floor flange, it is possible to easily check the deviation between the mark portion of the floor flange and the position adjustment mark of the drain socket. Therefore, the drain socket can be accurately aligned with the floor flange.

  According to the present invention, when the drain socket is replaced, the existing screw hole provided in the floor surface is reused so that the drain socket can be fixed without newly providing a screw hole to the floor surface. A flange can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In order to facilitate the understanding of the description, the same constituent elements in the drawings will be denoted by the same reference numerals as much as possible, and redundant description will be omitted.

<First Embodiment>
FIG. 1 is a plan view and a cross-sectional view of the floor flange 100 of the first embodiment. 1A is a plan view of the floor flange 100, FIG. 1B is a cross-sectional view taken along line B-B in FIG. 1A, and FIG. 1C is AA in FIG. It is arrow sectional drawing in a line.

  As shown in FIG. 1, the floor flange 100 of the first embodiment is configured by a substantially flat flange portion 110. The flange portion 110 is formed with a circular opening 112 through which a drain pipe 20 rising from the floor surface 10 to be described later is inserted, and is installed so that the lower end surface 118 of the flange portion 110 is in contact with the floor surface 10. . Therefore, the lower end surface 118 of the flange portion 110 is an installation surface for the flange portion 110.

  On the upper end surface 114 formed on the opposite side of the lower end surface 118 of the flange portion 110, mark portions 120 are formed in four directions around the opening 112. Specifically, of the four mark portions, two mark portions 120 are formed along the line AA that is a straight line passing through the center point of the opening 112, and the flange portion 110 is sandwiched between the openings 112. It is formed on both sides. The remaining two mark portions 120 are formed along the BB line, which is a straight line that passes through the center point of the opening 112 and is perpendicular to the AA line, and both sides of the flange portion 110 across the opening 112. Is formed.

  Since the AA line and the BB line intersect at a right angle, when the center point of the opening 112 is the vertex, the angle formed by the adjacent mark portions 120 is 90 degrees, and the other adjacent mark portions 120 are adjacent to each other. The angles formed by are all 90 degrees.

  Further, as shown in FIGS. 1B and 1C, the opening 112 is expanded from the upper end surface 114 to the lower end surface 118 of the flange portion 110 so that the diameter of the opening 112 increases. The cross-sectional shape is trapezoidal. Therefore, in the opening 112, the intermediate surface 116 formed between the upper end surface 114 and the lower end surface 118 of the flange portion 110 does not contact the floor surface 10. Further, since the intermediate surface 116 is an inclined surface, the flange portion 110 faces the floor surface 10 when the flange portion 110 is installed on the floor surface 10. Therefore, the intermediate surface 116 is spaced apart from the floor surface 10, and when the flange portion 110 is installed on the floor surface 10, a gap is formed between the intermediate surface 116 and the floor surface 10.

  Next, a method for replacing the existing drain socket 40 with a new drain socket 60 using the floor flange 100 of the first embodiment will be described with reference to FIGS.

  First, the process of removing the existing flush toilet 30 and the existing drainage socket 40 will be described with reference to FIG. FIG. 2A is a view showing a state in which the existing flush toilet 30 and the existing drain socket 40 are attached to the floor surface 10.

  As shown in FIG. 2A, an existing flush toilet 30 is attached to the floor surface 10. Specifically, the existing flush toilet 30 has a rear portion fixed by a bolt 42 provided in an existing drain socket 40, and a front portion fixed to an existing front fixing piece 50 by screws. Yes. Thus, the existing flush toilet 30 is fixed to the floor surface 10 via the existing drain socket 40 and the existing front fixing piece 50. Further, the drainage port of the existing flush toilet 30 is connected to the drainage pipe 20 provided on the floor surface 10 via the existing drainage socket 40.

  Therefore, when the existing flush toilet 30 is removed, the existing drain socket 40 and the existing front fixing piece 50 attached to the floor surface 10 are left as shown in FIG. The existing drain socket 40 and the existing front fixing piece 50 are fixed to the floor surface 10 with screws 44 and screws 52. Therefore, the existing drain socket 40 and the existing front fixing piece 50 can be removed from the floor surface 10 by removing the screw 44 and the screw 52.

  When the existing drain socket 40 and the existing front fixing piece 50 are removed, the drain pipe 20 is exposed as shown in FIG. Further, the screw hole 45 of the screw 44 that has fixed the existing drain socket 40 and the screw hole 53 of the screw 52 that has fixed the existing front fixing piece 50 remain on the floor surface 10. Since the screw hole 45 and the screw hole 53 are provided when the floor surface 10 is constructed, the positions of the underfloor heating wiring 12 and the underfloor piping part 22 are known in advance, and are opened so as to avoid them. ing.

  Next, a process of transferring the screw hole position 46 of the existing drain socket 40 to the floor flange 100 of the first embodiment will be described with reference to FIG. FIG. 3A is a diagram illustrating a state in which the existing drain socket 40 is stacked on the floor flange 100 of the first embodiment, and FIG. 3B is an existing drain socket 40 on the flange portion 110 of the floor flange 100. It is a figure showing the state by which the screw hole position 46 of this was transferred.

  First, the screw hole position 46 of the existing drain socket 40 is transferred to the floor flange 100 shown in FIG. For this purpose, as shown in FIG. 3A, the existing drain socket 40 removed from the floor surface 10 is placed on the upper end surface 114 of the flange portion 110 and aligned with the mark portion 120 formed on the flange portion 110. . In the existing drain socket 40, a position adjusting convex portion 48 (position adjusting mark) is provided in order to align the center of the drain pipe connecting portion (drain core) (not shown) of the existing drain socket 40 with the center of the drain pipe 20. Is formed. Therefore, when the position of the position adjusting convex portion 48 and the mark portion 120 are aligned and the screw hole position 46 of the existing drain socket 40 is transferred to the flange portion 110, the transferred floor fixing screw hole 122 is used. When the floor flange 100 is fixed to the floor surface 10, the center of the opening 112 and the drain pipe 20 can be aligned.

  In order to transfer the screw hole position 46 of the existing drain socket 40 after aligning the existing drain socket 40 with respect to the floor flange 100, for example, with the existing drain socket 40 aligned, a punch or the like With this tool, the screw hole position 46 of the existing drain socket 40 is marked on the flange portion 110 of the floor flange 100, and then drilled using a drill or the like. By doing in this way, as shown in FIG.3 (b), the screw hole position 46 of the existing drain socket 40 can be transcribe | transferred with respect to the floor flange 100 as the screw hole 122 for floor fixation.

  Next, a process of transferring the screw hole position 66 of the new drain socket 60 to the floor flange 100 of the first embodiment will be described with reference to FIGS. 4 and 5. FIG. 4 is a view showing a pattern 90 in which the screw hole position 66 of the new drain socket and the position of the bolt 72 of the new flush toilet 70 are depicted. 5A is a plan view showing the floor flange 100 to which the screw hole position 66 and the position of the bolt 72 are transferred using the pattern 90 of FIG. 4, and FIG. 5B is a view of D in FIG. 5A. FIG. 5C is a sectional view taken along the line CC in FIG. 5A.

  As shown in FIG. 4, two center lines 92 for position adjustment are drawn on the pattern 90 to align with the mark part 120 provided on the flange part 110. The two center lines 92 for position adjustment are drawn so as to intersect at right angles at the center of the drain pipe 20. Further, the pattern 90 has a screw hole position 66 of the new drain socket 60 and a bolt 72 for fixing the rear portion of the new flush toilet 70 with reference to the center of the drain pipe 20 and the center line 92 for position adjustment. The position is filled in full size.

  Accordingly, by using the pattern 90, the screw hole position 66 of the new drain socket 60 and the position of the fixing bolt 72 of the new flush toilet 70, which are written on the pattern 90, can be transferred to the flange portion 110. . In this transfer, the screw hole position 66 of the new drainage socket 60 and the bolt for fixing the new flush toilet 70 are fixed by a tool such as a punch in the same manner as when the screw hole position 46 of the existing drainage socket 40 is transferred. 72 is marked on the flange portion 110 of the floor flange 100, and then drilled using a drill or the like. In this way, as shown in FIG. 5A, the screw hole position 66 of the new drainage socket 60 and the position of the fixing bolt 72 of the new flush toilet 70 with respect to the floor flange 100 are changed to the drainage socket. The fixing screw hole 124 can be transferred.

  Further, as shown in FIGS. 5B and 5C, the fixing bolt 72 is provided at the hole position of the fixing bolt 72 of the new flush toilet 70 transferred to the flange portion 110. It is inserted from the lower end surface 118 side. At this time, in order to prevent the head 72 a of the fixing bolt 72 from protruding from the lower end surface 118 of the flange portion 110, a recess 126 is formed on the lower end surface of the flange portion 110.

  In order to designate the position of an object on a plane, information on two directions on the plane, such as a horizontal position and a vertical position, and information defining the direction of the object are required. Therefore, in order to make the positions and orientations of the two drain sockets coincide with each other, at least three mark portions 120 are required. In this regard, since the floor flange 100 of the first embodiment is provided with the mark portions 120 in the four directions around the opening 112, the position of the existing drain socket 40 and the new drain socket 60 in the front-rear direction with respect to the drain pipe 20 is determined. And the mounting angle can be matched. Thereby, when the new drain socket 60 is attached via the floor flange 100, the drain pipe connection portion (not shown) of the new drain socket 60 is displaced from the drain pipe 20 or is displaced from the mounting direction of the existing drain socket 40. Can be prevented.

  Further, in the floor flange 100 of the first embodiment, the mark portion 120 has the center point mark portion 120 of the opening 112 and the center point of the opening 112 is the apex, so that the angle between the mark portions 120 adjacent to each other is 90 degrees. It is formed in 4 places. By doing in this way, for example, it becomes easier to confirm the displacement with respect to the floor flange 100 than in the case where the mark portion 120 is formed to be biased to a certain angle range. The case where the mark portion 120 is formed so as to be deviated within a certain angle range means, for example, that three of the four mark portions 120 are formed together within a range of 90 degrees from the center of the opening 112. Etc. Therefore, in the floor flange 100 of the first embodiment, when the existing drain socket 40 or the paper pattern 90 is aligned with the floor flange 100, it is easy to check the deviation from the mark portion 120 of the floor flange 100. Therefore, the existing drain socket 40 and the new drain socket 60 can be aligned with respect to the floor flange 100 with high accuracy.

Subsequently, referring to FIG. 6, the screw hole position 54 of the existing front fixing piece 50 and the screw hole 83 of the new front fixing piece 80 are attached to the fixing piece floor flange 200 for attaching the new front fixing piece 80. A process of transferring the position will be described.
6A is a plan view of the fixed-piece floor flange 200, FIG. 6B is a cross-sectional view taken along the line EE of the fixed-piece floor flange 200 shown in FIG. 6A, and FIG. FIG. 6D shows a pattern 94 in which the position of the screw hole 83 of the front fixing piece 80 is drawn. FIG. 6D shows the screw hole position 54 of the existing front fixing piece 50 and the screw hole 83 of the new front fixing piece 80. It is the top view of the floor flange 200 for fixed pieces transferred.

  First, the screw hole position 54 of the screw hole 53 of the existing front fixing piece 50 is transferred to the fixing piece floor flange 200 shown in FIGS. 6 (a) and 6 (b). For this purpose, the existing front fixing piece 50 removed from the floor surface 10 is placed on the upper end surface 202 of the fixing piece floor flange 200, and the center of the existing front fixing piece 50 is formed on the upper end surface 202 of the fixing piece floor flange 200. Align with the groove 208 formed. Since the existing front fixing piece 50 and the new front fixing piece 80 have a bilaterally symmetric shape, the positions of the existing front fixing piece 50 and the new front fixing piece 80 in the left-right direction can be obtained by aligning the center with the groove 208. Can be combined.

  Further, with respect to the front and rear positions, the screw hole position 54 of the existing front fixing piece 50 to be transferred is aligned with the position where the floor fixing hole processing portion 210 overlaps. As shown in FIG. 6B, the fixing piece floor flange 200 is formed with a recess 206 having a recessed lower end surface 204 at a portion other than the floor fixing hole processing portion 210. Therefore, if the screw hole position 54 of the existing front fixing piece 50 is transferred to the recess 206, the fixing piece floor flange 200 may be deformed when the fixing piece floor flange 200 is fixed to the floor surface 10. The front and rear positions are aligned so that the screw hole position 54 of the existing front fixing piece 50 overlaps the floor fixing hole processing portion 210.

  Next, using the pattern 94 on which the position of the screw hole 83 of the new front fixing piece 80 shown in FIG. 6C is drawn, the position of the screw hole 83 of the new front fixing piece 80 is set on the floor flange 200 for fixing piece. Transcript. A center line 96 for position adjustment is drawn on the pattern paper 94 in order to align with the groove 208 of the floor flange 200 for the fixed piece. Therefore, the position of the screw hole 83 is transferred by aligning the position adjusting center line 96 with the groove 208. When the position of the screw hole 83 is transferred using the pattern paper 94, the front and rear positions are aligned so that the screw hole 83 overlaps the recess 206. This is because the new front fixing piece 80 is fixed by the bolt 212 so that the head of the bolt 212 fits in the concave portion 206 of the fixing piece floor flange 200. Thus, when the screw hole position 54 of the existing front fixing piece 50 and the screw hole 83 of the new front fixing piece 80 are transferred to the fixing piece floor flange 200, the fixing piece floor flange 200 is The state shown in FIG.

  Subsequently, a process of attaching the new drain socket 60 to the floor surface 10 using the floor flange 100 to which the screw hole position 46 of the existing drain socket 40 and the screw hole position 66 of the new drain socket 60 are transferred is shown in FIG. A description will be given with reference to FIG.

  7A is a plan view showing a state in which the floor flange 100 of the first embodiment is attached to the floor surface 10, FIG. 7B is a cross-sectional view taken along the line FF of FIG. 7A, and FIG. c) is an enlarged view of a dotted line portion P in FIG. 8A is a plan view showing a state in which a new drain socket 60 is attached via the floor flange 100, and FIG. 8B is a cross-sectional view taken along the line GG in FIG. 8A.

  As shown in FIG. 7A, the floor flange 100 is fixed to the floor surface 10 using floor fixing screw holes 122 provided in the flange portion 110. Since the screw hole 122 for fixing the floor is a transfer of the screw hole position 46 of the existing drain socket 40, the screw hole 122 for fixing the floor coincides with the screw hole 45 already formed on the floor surface. The floor flange 100 can be fixed to the floor surface 10 by reusing the holes 45.

  Similarly to the floor flange 100, the fixed piece floor flange 200 is also fixed to the floor surface 10 using a screw hole position 54 provided in the fixed piece floor flange 200. Since the screw hole position 54 provided in the fixed piece floor flange 200 is a transfer of the screw hole 54 of the existing front fixed piece 50, the screw hole position 54 of the fixed piece floor flange 200 is formed on the floor surface 10. It coincides with the screw hole 53 that has already been opened. Therefore, the fixing piece floor flange 200 can be fixed to the floor surface 10 by reusing the screw holes 53. Further, as shown in FIG. 7B, the new front fixing piece 80 is fixed by a bolt 84 inserted through a screw hole 83 transferred to the fixing piece floor flange 200.

  Further, as shown in FIGS. 7A and 7B, the floor flange 110 is fixed to the floor surface 10 using the floor fixing screw holes 122, so that the center of the opening 112 is the center of the drain pipe 20. Therefore, as shown in FIGS. 7A and 7B, the drain pipe 20 can be fixed to the opening 112 of the floor flange 100.

Here, the unevenness 14 formed on the floor surface 10 will be described with reference to FIG. As shown in FIG. 7C, when a gap is formed between the floor surface 10 and the drain pipe 20, it is generally blocked by a mortar 16 or the like. Therefore, a portion where the mortar 16 is raised above the floor surface 10 is formed around the drain pipe 20, and a portion where the mortar 16 is raised above the floor surface 10 is uneven. When the floor flange 100 is fixed to the floor surface 10 in a state where the floor flange 100 is in contact with the uneven surface 14, the floor flange 100 is deformed.
However, the opening 112 of the floor flange 100 of the first embodiment is formed with an intermediate surface 116 that is inclined so that the diameter of the opening 112 increases from the upper end surface 114 to the lower end surface 118 of the flange portion 110. When the floor flange 100 is fixed to the floor surface 10, a gap is formed between the intermediate surface and the floor surface 10, and contact with the non-land 14 formed around the drain pipe 20 can be prevented. Therefore, when the floor flange 100 is fixed to the floor surface 10, the floor flange 100 can be prevented from coming into contact with the non-land 14 and being deformed.

  Subsequently, a new drain socket 60 is attached to the floor flange 100 attached to the floor surface 10. The new drain socket 60 is fixed to the drain socket fixing screw hole 124 transferred to the flange portion 110 of the floor flange 100 by screws 62. The screw 62 has a length that does not exceed the lower end surface 118 of the floor flange 100 when the new drain socket 60 is fixed to the floor flange 100. Therefore, by fixing the new drain socket 60 using the drain socket fixing screw hole 124, no screw hole is formed in the floor surface 10.

As described above, by using the floor flange 100 of the first embodiment, a new drain socket 60 can be attached by reusing the screw hole 45 of the existing drain socket 40 opened in the floor surface 10. When the new drain socket 60 is attached, a new screw hole is not formed in the floor surface 10. Therefore, it can suppress that the underfloor piping part 22 of the drain pipe 20, the underfloor heating wiring 12, etc. are damaged.
The fixed piece floor flange 200 can also fix the new front fixed piece 80 by reusing the screw hole position 53 of the existing front fixed piece 50. Therefore, in the fixed piece floor flange 200, when a new front fixed piece 80 is attached, no new screw hole is made in the floor surface 10. Therefore, the underfloor piping portion 22 of the drain pipe 20, the underfloor heating wiring 12, etc. Can be prevented from being damaged.

  Finally, the process of attaching a new flush toilet 70 to a new drain socket 60 and a new front fixing piece 80 will be described with reference to FIG. 9A is a plan view showing a state in which a new flush toilet 70 is attached to the floor surface 10, and FIG. 9B is a cross-sectional view taken along the line HH in FIG. 9A.

  As shown in FIGS. 9A and 9B, the bolt 72 provided on the floor flange 100 of the first embodiment fixed to the floor surface 10 and the fixed piece fixed to the floor surface 10. The new flush toilet 70 is fixed to the new front fixing piece 80 attached to the floor flange 200. As shown to Fig.9 (a) and (b), the new flush toilet 70 is fixed with the volt | bolt 72 provided in the floor flange 100 of 1st Embodiment in the rear part. Further, the front portion is fixed by inserting a screw 74 from the outer surface portion of the new flush toilet 70 and screwing it to a new front fixing piece 80 attached to the floor flange 200 for the fixing piece. Further, since the new drain socket 60 and the new front fixing piece 80 are fixed to the floor surface 10 via the floor flange 100 and the fixing piece floor flange 200, the floor flange 100 and the fixing piece floor flange are fixed. A gap is generated between the new flush toilet 70 and the floor 10 by the thickness of 200. Therefore, a gap filling member 84 is sandwiched between the new flush toilet 70 and the floor surface 10 in order to close this gap.

<Modification>
As mentioned above, although embodiment of the technique which this application discloses was described, the technique which this application discloses is not limited above.
