BACKGROUND OF THE INVENTION
The present invention relates to a construction structure and a construction method of a sanitary facility, and more particularly, to a sanitary facility construction method capable of performing construction from a Japanese-style toilet to another sanitary facility in a short construction period only by work from an installation floor.
[0002]
[Prior art]
In renovation work from Japanese-style toilets to other sanitary facilities in multi-story buildings,
Conventionally, there is one as seen in JP-A-59-224738. This was invented to eliminate work from downstairs when renovating sanitary facilities on the floor, and the existing drainpipe was exposed by removing the toilet bowl of an existing Japanese-style toilet. After the connecting pipe is erected, mortar and the like are backfilled inside the connecting pipe and the toilet bowl.
[0003]
[Problems to be solved by the invention]
By the way, when performing such renovation work, if the drainage pipe of a newly installed sanitary facility is inside an existing Japanese style toilet, it can be constructed with the technology described in Japanese Patent Laid-Open No. 59-224738 as it is. Met. If it is necessary to install drainage pipes for newly installed sanitary facilities outside the existing Japanese-style toilet bowl due to the type, number, orientation, etc. of the new sanitary facilities, the floor under the outside of the Japanese-style toilet bowl will be combined in a short period of time. Construction related to is required.
[0004]
Therefore, according to the present invention, even if it is necessary to install the piping outside the existing Japanese-style toilet bowl due to circumstances such as the type, number and direction of the new sanitary facilities, the work is repaired in a short period of time only from the installation floor. It aims at providing the construction structure which can be done.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the present invention, the construction structure is constructed from an existing Japanese-style toilet bowl to another sanitary equipment, and is removed by cutting the upper part of the toilet bowl of the Japanese-style toilet bowl. and water outlet, by removing the connection pipe insertion opening formed so as to expose the drain port of the Japanese-style toilet, a bed specifications upper corresponding to the position where the connection pipe is embedded connecting to said connection pipe does not protrude depth to form a subfloor unit, said for passing the connecting pipes to the toilet bowl side wall of Japanese bowl, the bowl side wall removed portion by removing a portion of the side wall corresponding to the subfloor unit has been formed position forming a, around the side wall removed portion, after placing the asphalt sheet to straddle said side wall removed portion and the underfloor section, is inserted one end of the connecting pipe to the connecting pipe insertion port The other end of the connection pipe By connecting the regulations sanitation water outlet, said to directly connect the new sanitation drainage port and the existing said connecting pipes and Japanese toilet drainage port of the said connecting pipe through the side wall removed portion Provided is a sanitary facility construction structure that is installed in a floor foundation part, and a filler is poured into the floor foundation part and the existing Japanese-style toilet.
[0006]
In this invention, even if it is necessary to provide the piping outside the existing Japanese-style toilet bowl due to the circumstances of the type, number, orientation, etc. of the new sanitary equipment, without pulverizing and removing all the existing Japanese-style toilet bowl, It is possible to perform repair work in a short period of time only from the installation floor.
In addition, since a connecting pipe is buried outside the Japanese-style toilet and an asphalt sheet is placed so as to straddle the removal part and the floor base part, the Japanese-style toilet can be flowed at once without leaking the filler downstairs. The inside of the toilet bowl and the external connection piping buried part can be watertightly constructed at the same time.
Furthermore, when the material for the drainage pipe of a newly installed sanitary facility is PVC, the drainage pipe is covered with a filler, so that a fireproof structure can be obtained.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a plan view showing the positional relationship between existing Japanese-style toilets and piping of new sanitary equipment. FIG. 2 is a cross-sectional view taken along the line AA in FIG.
[0008]
In the existing Japanese style toilet 5 in FIG. 1, in order to make the installation surface of the new sanitary equipment flush with the conventional floor finish surface, the front rim portion 16 and the outer peripheral rim portion 14 protruding above the floor finish surface 100 are provided. Cutting is in progress. Unless the installation surface of the new sanitary equipment is the same as the conventional floor finish surface 100, the outer peripheral rim portion 14 of the Japanese-style toilet 5 protruding from the floor finish surface 100 does not need to be cut. The cutting method is disclosed below.
[0009]
In FIG. 3, when cutting the placket part 16, a marking line 15 is inserted with a magic 12 about 10 mm above the upper surface of the rim part 14 of the Japanese-style toilet 5. When placing the marking line 15 inside the placket 16, it is easy to work with the marking jig 13. The marking jig 13 is made of a simple material such as paper or a veneer board, but the material is not particularly limited.
[0010]
Next, a marking line 17 for cutting the rim portion 14 is inserted. FIG. 4 is a perspective view when the marking line 17 is inserted. The method of putting the marking line 17 can be performed by a method that is not different from that of the above-described placket 16.
[0011]
Here, the cutting dimension of the rim portion 14 will be described. FIG. 5 is a cross-sectional view of the vicinity of the rim portion 14 of the Japanese-style toilet 5. The existing Japanese style toilet 5 is fixed such that the lower water bag 24 is caught by the slab 23 via the support base 25.
[0012]
D in FIG. 5 represents the range of the rim to be cut. When the rim is cut deeper than the protrusion 24 is caught on the floor slab 23, that is, when the rim portion 14 is cut at a position deeper than the depth d, the Japanese-style toilet 5 loses the fixing means to the floor slab 23 and goes downstairs. There is a possibility of falling.
Although there is no clear standard for the rim depth dimension of the Japanese-style toilet bowl 5, according to the test by the sample conducted by the present applicant, if the depth d from the upper surface of the rim is set to a dimension of 70 mm or less, it protrudes from the floor. Even if the rim portion 14 of the Japanese-style toilet 5 is cut, the Japanese-style toilet 5 does not seem to fall downstairs.
[0013]
The Japanese-style toilet 5 is cut in accordance with the marking line thus inserted. The tool uses a disc grinder 18. First, the placket 16 is cut according to the marking line 15. Next, the rim portion 14 is cut according to the marking line 17. The disc grinder 18 is a hand work, but if the disc grinder 18 is fixed to an aluminum frame or the like so that it can be cut at a certain height, the efficiency is further improved.
[0014]
In order to make it easy to remove the cut pieces, it is easy to remove the cut pieces by inserting a plurality of marking lines 19 as shown in FIG. 6 and making a cut vertically with the disc grinder 18 along the marking lines 19.
In this way, the Japanese-style toilet 5 having the entire upper surface cut from the floor finish surface 100 as shown in FIG. 1 is obtained.
[0015]
Next, the portion where the connection pipe 6 is to be buried is deleted, and the floor foundation 3 is formed.
When removing the portion where the connection pipe 6 is to be installed, the floor foundation 3 is formed to a depth such that the connection pipe 6 does not protrude from the floor finish surface 100. The shallower the depth to be removed, the easier the construction, but it is necessary to secure at least 100 mm in consideration of the dimensions from the upper surface of the flange to the lowest part of the connection pipe 6 and the thickness of the asphalt sheet 9 to be constructed later. .
[0016]
Next, the toilet bowl side wall of the Japanese style toilet bowl 5 through which the connection pipe 6 should pass is cut. The cutting is similar to the cutting of the placket and rim 14 described above, and has the same cross section as the floor base 3 in this embodiment. FIG. 7 shows the state after cutting.
[0017]
In the above-described embodiment, the floor base portion 3 where the connection pipe 6 is to be buried first is removed, and then the toilet bowl side wall of the Japanese-style toilet 5 is cut, but the order may be reversed.
Further, in the present embodiment, the toilet bowl side wall has the same cross section as the floor base 3 by cutting, but it is also possible to make a hole through which the connection pipe 6 passes.
[0018]
When the above-described Japanese style toilet 5 is cut, the relationship with the floor slab 23 is the AA cross section of FIG. 1, which is shown in FIG. Here, due to the difference in the construction method of the Japanese-style toilet 5, the gap 7 may be generated due to the relationship between the floor slab 23 and the Japanese-style toilet 5. In addition, even when the floor slab 23 wraps around the drainage outlet of the Japanese-style toilet 5 and the gap 7 is not necessarily generated, when the filler is poured to cover the connecting pipe 6, There is concern about the outflow of filler.
[0019]
Therefore, the asphalt sheet 9 covers the side wall removing portion and the floor foundation portion 3 of the Japanese-style toilet 5. FIG. 8 shows a state where the asphalt sheet 9 is covered. The asphalt sheet 9 has water tightness, strength and followability at the same time. Examples of the sheet having the same kind of performance include a vinyl chloride sheet and an aluminum tape. The thickness of the asphalt sheet 9 is desirably 0.4 mm or less. If the thickness is 0.4 mm or more, the Japanese style toilet 5 and the floor 8 cannot be followed. The asphalt sheet 9 can be made to follow more easily by cutting with a cutter 10 or the like.
[0020]
It is also possible to apply a pasty epoxy resin in advance just before the asphalt sheet 9 is attached. In this way, the gap 7 can be filled more reliably. FIG. 9 shows a state in which an epoxy resin 11 is applied around the gap 7 immediately before the asphalt sheet 9 is attached. The epoxy resin 11 is two-component and is cured by mixing the main agent and the curing agent. The main component is an epoxy resin. The component of the curing agent is polythiol, and it is desirable that it has low fluidity and is quick-drying.
[0021]
In the present invention, an asphalt sheet is used to fill the gap 7. This requires watertightness, follows the floor foundation and Japanese toilet bowl removal shape, further maintains the strength to support the weight of the mortar described later, withstands the reaction heat of the mortar, and is inexpensive. It is because it is satisfied. As an alternative to asphalt sheets, PVC sheets or aluminum sheets can withstand use under the same conditions. The thickness in this case must be at least 1 mm to ensure strength. When it is thicker, the followability is poor. A glass fiber sheet can also be used. In this case, it is only necessary to use a sheet having a minimum roughness of 300 series and impregnated with unsaturated polyester as a backup resin.
[0022]
A connecting pipe 6 is installed on the floor base 3 formed in this way. FIG. 2 shows a perspective view thereof. It is common to insert the connection pipe 6 into the connection pipe insertion port 1 and secure the water tightness using the adhesive 20 around it, but if it is a structure that prevents the outflow of the filler to be poured later, This structure is not particularly specified.
[0023]
By pouring the filler into the Japanese-style toilet 5 and the floor foundation 3, the connection pipe 6 is fixed in a watertight manner, and at the same time, fireproof coating can be achieved. As the type of filler, normal Portland cement may be used, but cracks of the Japanese-style toilet 5 are generated, so that a material having a significant difference in expansion and contraction upon curing is not suitable.
[0024]
【The invention's effect】
The present invention, even if it is necessary to provide the piping outside the existing Japanese-style toilet bowl due to circumstances such as the type, number and orientation of the new sanitary equipment, without pulverizing and removing all the existing Japanese-style toilet bowl, It is possible to perform repair work in a short period of time only from the installation floor.
In addition, a connecting pipe is embedded outside the Japanese-style toilet, and an asphalt sheet is placed so as to straddle the removal part and the floor base part, so that the mortar flows through the mortar all at once without leaking downstairs. The inside of the pot and the external connection piping buried part can be constructed watertight at the same time.
