It is what I did.
[0004]
[Problems to be solved by the invention]
However, in the former piping structure, since the piping member 104 having elasticity is used, it is possible to absorb the construction variation of the hot water supply pipes 102 and 103 and to improve the waterproofness of the piping portion. However, for example, when the hot water pipes 102 and 103 are not raised at the construction site when the system bus is constructed (the hot water pipes 102 and 103 are not piped in the pipe hole of the pipe portion 101), the indoor pipe of the system bus The problem is that it is inferior in the work efficiency of the construction and that the construction period of the system bus is likely to be prolonged, such as the necessity of performing indoor piping at the site after the plumbing of the hot water hot water pipes 102 and 103. Have.
[0005]
Further, in the latter piping structure, the resin plate 107 has a structure in which two holes 107a are formed in the resin plate 107 according to the piping state of the hot water supply pipes 102 and 103 at the construction site. Although the configuration can be simplified and the cost can be reduced, the indoor piping cannot be performed when the hot water supply pipes 102 and 103 are not raised at the construction site, similarly to the former piping structure. Has a problem. In this latter case, if the faucet adapter is attached to the bored hole 107a, the indoor piping can be performed first, and the above problem can be solved, but the hole in the resin plate 107 to which the faucet adapter is attached. The 107a portion needs to be waterproofed, so that the workability of the construction is inferior, and there are problems that the waterproofing work is likely to vary and it is difficult to maintain a stable waterproof property over a long period of time.
[0006]
That is, both the former and the latter piping structures can be used for indoor piping regardless of the state of the hot water supply pipes 102, 103, or when the hot water supply pipes 102, 103 are standing up, facilitating waterproofing processing, Or, in reality, it is very difficult to easily cope with the case where the rising positions of the hot water supply pipes 102 and 103 vary. The present invention has been made in view of such circumstances, and an object of the present invention is to perform indoor piping regardless of the piping state of the hot water supply pipe, as well as facilitating waterproofing and piping variations in the hot water supply pipe. It is another object of the present invention to provide a set part for a piping structure of a hot water pipe that can easily cope with the above.
[0007]

In FIG. 1, a pipe portion 1 provided at a predetermined position such as a lower part or a bottom part of a waterproof pan of a system bus has, for example, a substantially elliptical pipe hole 1 a formed when the waterproof pan is formed. The water supply pipe 2 and the hot water supply pipe 3 are vertically piped by the plate member 4 and the two waterproof members 5 in the pipe hole 1a. That is, the plate-like member 4 made of, for example, ABS resin shown in FIG. 2 is fixed to the upper surface of the pipe hole 1a by the wood screws 7 using the mounting holes 4b at the four corners. The waterproof members 5 are respectively fitted and arranged in the two holes 4a.
[0011]
The waterproof member 5 is formed in a substantially cylindrical shape shown in FIG. 3 by a molded product of an elastic material such as rubber, and includes a lower fitting portion 8 and a through portion 9 provided on the upper portion of the fitting portion 8. Yes. An annular fitting groove 8a is formed in the outer peripheral wall of the fitting portion 8, and the through portion 9 has a large diameter portion 9a having an inner diameter larger than the outer diameter of the water supply pipe 2 or the hot water supply pipe 3, and this diameter. The small diameter portion 9b is provided on the large portion 9a and has an inner diameter substantially the same as the outer diameter of the water supply pipe 2 or hot water supply pipe 3.
[0012]
The fitting groove 8a of the fitting portion 8 of the waterproof member 5 is fitted and fixed to the hole 4a of the plate-like member 4 via an adhesive or the like as will be described later, and the fitting portion 8 of the waterproof member 5 is fixed. And the large diameter part 9a and the small diameter part 9b are arrange | positioned in the state which the water supply pipe | tube 2 and the hot water supply pipe | tube 3 penetrate from upper direction to the downward direction. The small diameter portion 9 b of the waterproof member 5 is fastened to the water supply pipe 2 and the hot water supply pipe 3 by the hose band 10, so that the water supply pipe 2 and the hot water supply pipe 3 are made watertight by the plate-like member 4 and the waterproof member 5. It has been piped to the piping part 1.
[0013]
Next, a specific piping method using the plate-like member 4 and the waterproof member 5 will be described with reference to FIGS. First, as shown to Fig.4 (a), when the water supply pipe 2 and the hot water supply pipe 3 are piped by the predetermined piping pitch p1 in the piping hole 1a of the piping part 1 of a waterproof pan, FIG.4 (b) As shown in FIG. 2, the plate-like member 4 has two holes 4a having a hole pitch p2 corresponding to the pipe pitch p1 and an inner diameter corresponding to the outer diameter of the fitting groove 8a of the waterproof member 5, and mounting holes at the four corners. 4b is drilled.
[0014]
When the hole 4a is drilled, the fitting grooves 8a of the two waterproof members 5 that are set together with the plate member 4 are formed in the hole 4a, and an adhesive or the like is formed in the hole 4a of the drilled plate member 4. A state shown in FIG. 4C is obtained by fitting through silicon or the like. In this state, the plate-like member 4 is pushed down while the upper part of the water supply pipe 2 or the hot water supply pipe 3 is positioned in the fitting part 8 and the large diameter part 9b of the waterproof member 5, and the small diameter part 9b of the waterproof member 5 is placed. The lower surface of the plate-like member 4 is brought into close contact with the upper surface of the pipe portion 1.
[0015]
In addition, since the waterproof member 5 has elasticity when the water supply pipe 2 or the hot water supply pipe 3 penetrates the penetration part 9 of the waterproof member 5, the penetration part 9 is deformed as shown by a two-dot chain line a in FIG. While being penetrated, a smooth penetration state can be obtained, and the displacement of the piping pitch p1 and the hole pitch p2 can be easily absorbed. Further, when the fitting portion 8 of the waterproof member 5 is fitted into the hole 4a of the plate-like member 4, it can be smoothly performed by the elastic deformation.
[0016]
Then, when the plate-like member 4 is brought into close contact with the pipe portion 1, for example, a pilot hole is formed in the pipe portion 1 of the waterproof pan corresponding to the attachment holes 4 b at the four corners of the plate-like member 4. The plate-like member 4 to which the waterproof member 5 is fitted and fixed by screwing the wood screw 7 from the hole 4a to the lower hole of the pipe portion 1 (or directly without the lower hole) via a sealing agent such as silicon or the like. It is fixed to the piping part 1.
[0017]
In this state, as shown in FIG. 4 (d), the small diameter portion 9 b of the waterproof member 5 is fastened to the water supply pipe 2 and the hot water supply pipe 3 by the hose band 10, and the end portions of the water supply pipe 2 and the hot water supply pipe 3 are connected. By connecting the indoor pipe with a pipe joint or the like (not shown), the indoor piping work of the system bus can be performed when the hot water pipes 2 and 3 are piped on the pipe portion 1. The mounting hole 4b of the plate-like member 4 can be drilled in advance, or can be drilled at an appropriate position on the spot according to the situation at the construction site.
[0018]
The above is the piping method when the water supply pipe 2 and the hot water supply pipe 3 are installed in the piping hole 1a of the piping part 1, but the water supply pipe is inserted into the piping hole 1a due to a delay in the piping work when the system bus is constructed. When the 2 and the hot water supply pipe 3 are not piped, the indoor pipe is provided as shown in FIG. That is, as shown in FIG. 5A, in a state where the water supply pipe 2 and the hot water supply pipe 3 are not piped in the pipe hole 1a of the pipe section 1, as shown in FIG. Two holes 4a and four mounting holes 4b are formed in the plate-like member 4 at the piping pitch p3 set in step (1).
[0019]
Then, the two faucet adapters 6 that are set together with the plate-like member 4 and the two waterproof members 5 are inserted into the holes 4 a of the plate-like member 4 by using the tightening of the pair of nuts 11. To a state shown in FIG. The faucet adapter 6 is configured such that the indoor piping is connected to the connection portion 6a on the upper side in the figure, and the water supply pipe 2 and the hot water supply pipe 3 can be connected to the connection portion 6b on the lower side in FIG. 5 (d). ing.
[0020]
Next, when the faucet adapter 6 is fixed to the plate-like member 4, it is fixed on the pipe portion 1 with the wood screw 7 using the mounting hole 4 b of the plate-like member 4, as shown in FIG. The indoor pipe 12 is connected to the connecting portion 6 a at the top of the faucet adapter 6. Thereby, indoor piping when the hot water supply pipes 2 and 3 are not piped in the piping hole 1a can be performed, and the hot water supply pipes 2 and 3 indicated by a two-dot chain line are connected to the connecting portion 6b below the faucet adapter 6. Are connected, and the final piping work is completed.
[0021]
That is, by attaching one plate-like member 4, two waterproof members 5, and two faucet adapters 6 as a set to the system bus as construction parts, a water supply pipe is installed in the pipe hole 1 a of the pipe part 1. 2 and the hot water supply pipe 3 are of course selected, and even if the water supply pipe 2 and the hot water supply pipe 3 are not piped in the pipe hole 1a, the waterproof member 5 and the faucet adapter 6 can be selected. The indoor piping can be done with typical use.
[0022]
Thus, according to the piping structure and piping method of the above embodiment, when the hot water pipes 2 and 3 are piped in the piping portion 1 of the waterproof pan, the plate-like member 4 and the waterproof member 5 are used. Since indoor piping can be performed, and when the hot water pipes 2 and 3 are not piped in the piping part 1, indoor piping can be performed using the plate-like member 4 and the faucet adapter 6. Regardless of the piping condition of the hot water pipes 2 and 3, indoor piping can be performed on a predetermined construction day, and it is not necessary to go to the construction site again. Can be shortened.
[0023]
Moreover, since the plate-like member 4 capable of drilling the holes 4a is used as the piping member, the holes 4a are drilled according to the piping pitch p1 of the hot water supply pipes 2 and 3 piped to the piping portion 1. In addition, it is possible to easily cope with variations in piping, and by using a resin plate as the plate-like member 4, the hole 4a can be easily processed, or the cost of the component itself can be reduced. .
[0024]
Further, since the waterproof member 5 fitted and disposed in the hole 4a of the plate-like member 4 is integrally formed of an elastic material, the piping pitches p1 and p3 of the hot water pipes 2 and 3 are caused by the elastic deformation of the through-hole 9. And the hole pitch p2 of the perforated plate-like member 2 can be absorbed, and it is possible to easily cope with various variations, and for the piping member 104 in which eight conventional through portions 104a are integrally molded. Thus, the shape can be simplified, and the cost of the waterproof member 5 itself can be reduced.
[0025]
Further, since the annular fitting groove 8a is formed in the fitting portion 8 of the waterproof member 5, it is only necessary to fit the fitting groove 8a into the hole 4a of the plate-like member 4 while applying silicon or the like. As a result, a good sealing effect can be obtained, the workability of the sealing work can be improved, the waterproofness can be greatly improved as compared with the case where only the conventional resin plate 107 is used, and the variation of the sealing work can be improved. Occurrence can be suppressed, and stable waterproofness can be maintained over a long period of time.
[0026]
Furthermore, it is possible to cope with various piping states with a total of five minimum parts including the plate-like member 4, the two waterproof members 5 and the two faucet adapters 6, and the shape of the waterproof member 5 is simplified as described above. Although the number of parts increases due to the increase in the number of parts, the reduction of the number of parts, the elimination of the conventional fixing plate 105, the increase in the efficiency of various operations related to the construction, and the like can be achieved.
[0027]
In addition, in the said Example, although the case where two waterproofing members 5 and the faucet adapter 6 were provided was demonstrated, when two water supply pipes 2 and two hot water supply pipes 3 are piped, four waterproof members 5 grade | etc., Are provided. Use and pipe. Moreover, in the said Example, although the resin board was used as the plate-shaped member 4, a stainless steel board may be used, for example, and the shape of the waterproof member 5 employ | adopts the suitable shape which has a fitting part and a penetration part. The fixing structure to the plate-like member 4 is not limited to the adhesive or the like, and other appropriate fixing structures can be adopted. Furthermore, in the said Example, although the case where the piping part 1 was a waterproofing pan of a system bath was demonstrated, this invention is applicable to waterproofing pans, such as a washroom and a toilet, and the piping part of an appropriate floor member. it can.
