Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a toilet structure and a toilet construction method, and more particularly, to a structure and a method in which an old toilet bowl and a new toilet bowl can be easily exchanged.
[0002]
[Prior art]
In general, the floor structure around the toilet bowl in a toilet is a mortar layer formed on a concrete slab, and after forming a waterproof layer, concrete is placed as a waterproof press, and the floor surface material such as tiles is placed on the surface. There are many examples of constructions that are attached.
[0003]
In such a floor structure, for example, the case of exchanging from a Japanese style toilet to a Western style toilet will be described. First, the old toilet is demolished to form a recess in the floor, and the piping is exposed while leaving a waterproof layer. Subsequently, the cement is poured by placing a mold in the recess.
[0004]
Then, the old and new drainage portions are aligned by adding another pipe to the exposed pipe, and a waterproof layer is wound around the pipe to ensure the continuity of the waterproof layer. Finally, after applying tiles and other makeup on the floor surface, a new toilet is attached to the floor. In addition, when the age of the building has passed to such an extent that the toilet bowl is replaced in this way, the waterproof layer is often deteriorated, and even the waterproof layer may be removed.
[0005]
[Problems to be solved by the invention]
In the above-described method, the new and old drainage portions are aligned by adding another pipe to the exposed pipe. However, since this adjustment work is performed at the site, there is a problem that work efficiency is lacking. Conventionally, there are many cases where lead pipes are used as drainage pipes, but they are connected to new toilet pipes by forcibly bending or expanding the inner diameter.
[0006]
For this reason, there is a problem that the cost is increased and the construction period is extended, and the reliability of the joint portion is also lacking.
[0007]
Further, when cement is placed in a hole opened in the floor, it is difficult to maintain the same flatness with the surrounding floor surface, and as a result, there is a case where undulation that cannot be hidden by a decorative tile or the like occurs.
[0008]
The present invention has been made in view of the above matters, and even when exchanging old and new toilets, it is not necessary to perform on-site alignment due to the difference in the positions of the drainage ports of both, and the construction is easy, and the finish after construction is also excellent. It is an object to provide a toilet and a method of constructing the toilet.
[0009]

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the toilet and the construction method of the present invention will be described in more detail with respect to the embodiment shown in FIGS. The following form shows an example of adapting to a toilet on the second floor of a building.
<Embodiment 1>
Embodiment 1 is demonstrated based on FIGS.
[0016]
The existing floor surface 1 is laminated in the order of the deep layer portion to the concrete slab 12, the middle layer to the waterproof layer 13 and the upper layer to the mortar layer 14, and the construction plate 1a is pasted on the surface after the construction is completed.
[0017]
The old toilet (not shown) is, for example, a Japanese style toilet, and is first removed from the floor surface 1. After removing the old toilet, the inner wall 3a is cut and shaped to form the recess 3. When the old toilet is a Japanese-style toilet, it is often embedded in the floor, so the recess 3 may be formed by first cutting (3a) the periphery of the old toilet with a cutter or the like.
[0018]
At this time, the work is performed so as not to damage the waterproof layer 13 (asphalt layer of about 10 mm) as much as possible, and the work is cut to such a degree as not to reach the deepest concrete slab 12.
[0019]
Next, the case portion 6 is installed inside the recess 3. The case part 6 is a stainless steel case formed in a substantially funnel shape having an upper surface receiving port 4 and a drain port 5 at the bottom.
[0020]
Since this case part 6 is formed in a shape similar to that of the lower part of the Japanese-style toilet, the sewage can be flowed from any position from the upper surface receptacle 4. Further, a flange 6 a for attachment is provided around the case portion 6.
[0021]
The drain port 5 of the case part 6 is provided at a position where it can be connected to the existing drain pipe 7. That is, in the case of a Japanese style toilet, since the drain outlet is usually installed near the rear, the existing piping is also located near the rear of the case portion 6. Therefore, when the old toilet is a Japanese-style toilet, the drain port 5 of the case unit 6 is also set in advance toward the rear. If the old toilet is a Western-style toilet, the existing drainage pipe is installed closer to the front (the opposite side of the Japanese-style toilet), so the case section 6 has the drain outlet 5 installed closer to the front. Should be used.
[0022]
The waterproof layer 13 is sandwiched between the upper surface of the concrete slab 12 and the lower surface of the mortar layer 14, and is raised as shown in the figure so as not to break this. Moreover, it is good to join the new waterproof layer 15 to the waterproof layer 13 as needed.
[0023]
And the case part 6 is put into the recessed part 3, and it fixes to the concrete slab 12 through the volt | bolt 20 from the bolt hole (not shown) provided in the flange 6a.
[0024]
Subsequently, after the mortar 21 is filled below the flange 6a, the waterproof layer 13 or the new waterproof layer 15 is brought into close contact with the case portion 6 while being placed on the flange 6a. As the waterproof layer 13 or the new waterproof layer 15, for example, a melted asphalt between paper materials may be used, and the waterproof layer 13 or the new waterproof layer 15 may be configured to have a thickness of about 10 to 12 mm by overlapping three or four layers. Although the end of the old waterproof layer 13 is easily damaged, sufficient waterproofness can be obtained by bonding a new new waterproof layer 15. When such waterproof treatment is completed, the waterproof layer 13 is filled with cement or the like.
[0025]
The drain port 5 is set to have a larger inner diameter than the drain pipe 7 and is devised so that both can be easily joined even after the case portion 6 is attached.
[0026]
That is, the connecting pipe 22 is inserted from the drain port 5, and the tip of the connecting pipe 22 and the drain pipe 7 are connected. At this time, a sealing material 27 is filled between the connection pipe 22 and the drain pipe 7. Further, a packing ring 23 formed of soft rubber or high elasticity synthetic resin is inserted into the gap between the drain port 5 and the connecting pipe 22. At this time, it is desirable to use the caulking agent 24 together. As shown in FIG. 5, the packing ring 23 is C-shaped as shown in FIG. 5 or divided into two as shown in FIG.
[0027]
A fixing band 24 is attached to the outer peripheral portion of the packing ring 23 so that it can be firmly fixed. In addition, you may use together the locking tool 25 so that the connection pipe | tube 22 may not fall out during adhesion | attachment etc. The locking tool 25 is fixed to the upper part of the connection pipe 22. The caulking agent 24 causes the inner bottom surface of the case portion 6 to be at the same height as the top portion of the connection pipe 22, so that the sewage and the like in the case portion 6 is discharged well in the direction of the drain pipe 7. .
[0028]
In addition, since it is ideal that the drain port 5, the connection pipe 22, and the drain pipe 7 are located on a straight line, it is necessary to prepare a plurality of types of case portions 6 in which the positions of the drain ports 5 are changed as described above. Good. However, since the drainage port 5 is formed to have a larger diameter than the drainage pipe 7 and the connection pipe 22, a certain amount of positional deviation can be allowed.
[0029]
In the present embodiment, it is assumed that the old toilet is a Japanese-style toilet, but in the case of a Japanese-style toilet, the drain pipe 7 often rises only to a relatively low position. For this reason, the connection between the drain pipe 7 and the drain port 5 was made via the connection pipe 22. If the tip of the existing drain pipe 7 is at a sufficiently high position, it may be connected directly to the drain port 5. Further, after adjusting the height by cutting the upper portion of the drain pipe 7, it can be directly connected to the drain port 5 or connected via the connection pipe 22.
[0030]
As described above, according to the toilet and the toilet construction method in the present embodiment, all pipe connection operations can be performed from the upper part of the floor, so that it is less likely to affect the downstairs during construction. There is no hindrance to the use of the toilet.
[0031]
Thus, after connecting a pipe | tube, the cover board 9 which covers the upper surface receptacle 4 is installed. The cover plate 9 has an opening 8 at a position corresponding to the drainage portion 11 of the toilet 2, and a decorative plate 9 a is stretched on the upper surface thereof. Then, the lid plate 9 is placed on the support portion 30 provided at a position below the top portion by the thickness of the lid plate 9 in the upper portion of the inner surface of the case portion 6, and the upper surface of the lid plate 9 is the floor surface 1. It will be the same.
[0032]
And after a floor part is completed, the toilet bowl 2 is mounted | worn with the cover plate 9, and a new toilet is completed. The new toilet 2 may be installed over the floor surface 1 adjacent to the lid plate 9.
<Embodiment 2>
Next, a second embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the member same as the said Embodiment 1, and description is abbreviate | omitted.
[0033]
The toilet of this embodiment is particularly advantageous when used by an unspecified large number of people like a station toilet. That is, the toilet is capable of efficiently draining water sprayed on the floor by cleaning or the like, and water on the floor surface can be dropped into the case portion 6.
[0034]
The floor surface (for example, the floor surface of a single booth of a private toilet) is used as a full waterproof pan (floor construction with high water tightness), and a slit 17 is formed between the outer periphery of the lid plate 9 and the floor surface 1. . The slit 17 is formed as an annular gap by forming the size of the cover plate 9 slightly smaller than the inner periphery of the recess 3. Below the slit 17, a trap 18 made of a stainless material having a cross-sectional [U] shape (opening is upward) is disposed.
[0035]
As shown in FIG. 10, the trap 18 is provided so as to surround a wall portion 26 extending downward from the outer periphery of the lid plate 9 from the left and right, and an unevenness 18 a is formed at the upper end of the trap 18 located inside. Has been. The back surface of the cover plate 9 comes into contact with the convex portion of the unevenness 18a to support the cover plate 9. And the water in the trap 18 flows into the case part 6 from the recessed part of the unevenness | corrugation 18a. In addition, since this unevenness | corrugation is formed at regular intervals, the water which flowed in the trap 18 will fall into the case part 6 on average.
[0036]
When water flows in from the slit 17, as shown in FIGS. 7 and 8, the water in the trap 18 is divided by the wall portion 26 at the upper part. Thus, since it acts as a kind of siphon tube, the odor in the case part 6 does not go out and is hygienic.
[0037]
Further, in this embodiment, by using the waterproof pan, it is not necessary to consider much the waterproofness inside the floor.
[0038]
【The invention's effect】
According to the present invention, since the case part functions as a relay device that absorbs the difference in position of each pipe, even when replacing old and new toilets, it is not necessary to perform on-site alignment due to the difference in the position of the drainage outlets of both Is easy. For this reason, construction can be performed at low cost and the construction period can be shortened. In addition, it is highly reliable because there is no excessive machining on the piping.
[0039]
Moreover, since the lid plate is located around the toilet bowl, the finish after construction is excellent.
