Abstract

(57) [Summary] [Purpose] To provide drainage plumbing equipment for an apartment house that can reduce leakage of drainage noise generated at a toilet in the uppermost dwelling unit from the drain of the kitchen into the living room. [Composition] The ventilation pipes 3 and 5 of the toilet and the kitchen are integrally connected by the ventilation header 7 in the dwelling unit on the uppermost floor, and the trap cover 9 is attached to the drain of the kitchen. By inserting the silencer 8 in the middle of the header, drainage noise generated in the toilet is silenced and reduced by the silencer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage pipe facility for an apartment house, and more particularly to a drainage pipe facility for an apartment house that prevents drainage noise from flowing into a living room.

[0002]

[Prior art]

 Conventionally, in a drainage pipe facility in a dwelling unit on the top floor of an apartment house, for example, as shown in FIG. 4, a ventilation pipe 33 provided on an extension of a drainage pipe 32 of a toilet bowl 31 of a toilet is opened to the roof while a kitchen is opened. The ventilation pipe 37 provided on the extension of the drain pipe 35 of the sink 34 is integrally connected to the ventilation pipe 33 of the toilet by the ventilation header 37 which is piped in the ceiling, and the trap cover 38 is attached to the drain port of the sink 34. ing.

[0003]

[Problems to be solved by the device]

 However, in the conventional drainage piping system of an apartment, since the ventilation pipes of the toilet on the top floor and the kitchen are integrally connected by the ventilation header, the muffling performance of the trap cover of the kitchen is also low. , There is a problem that the drainage sound of a toilet leaks as drainage noise through the ventilation header and ventilation pipe and then out of the kitchen drainage port. Therefore, it is an object of the present invention to provide drainage piping equipment for an apartment house that can reduce drainage noise generated in a toilet on the top floor of the dwelling unit from leaking into the living room from the drainage outlet of the sink.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the drainage piping equipment of the present invention, the ventilation pipes of the toilet and the kitchen are integrally connected by the ventilation header in the uppermost dwelling unit, and the trap cover is attached to the drainage port of the kitchen. In the drainage piping equipment of the apartment house, a silencer is inserted in the middle of the ventilation head. The trap cover is preferably made of a solid and critical material.

[0005]

[Action]

 In the drainage piping system of the apartment house of the present invention, the drainage noise generated in the toilet is reduced by the silencer. By forming the trap cover with a solid and critical material, its sound insulation performance is enhanced. The muffler is preferably inserted near the ventilation pipe of the toilet, and is preferably made of a solid and critical material such as iron. Further, the material of the trap cover is preferably iron or the like, and is preferably covered with plastic.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of drainage piping equipment of an apartment house of the present invention. In the figure, reference numeral 1 is a drain pipe of a toilet bowl 2 of a toilet in the uppermost dwelling unit of an apartment house. An extension of the drain pipe 1 is provided with a vent pipe 3 open to the roof. In addition, the ventilation pipe 6 provided on the extension of the drain pipe 5 of the kitchen sink 4 in the dwelling unit on the top floor is integrally connected to the ventilation pipe 3 of the toilet by the ventilation header 7 that is laid in the ceiling. A silencer 8 is provided near the ventilation pipe 3 of the toilet in the middle of 7. The muffler 8 is a muffler to prevent the drainage noise of the toilet from propagating to the kitchen through the ventilation header 7 and the like. It is made of solid iron and the like. As shown in FIG. Inside the tubular body 8b provided with the flange 8a, the three baffles 8c having two through holes are arranged so that the through holes are not located on the same straight line and are appropriately separated in the axial direction. Is configured. On the other hand, the drain port of the sink 4 is equipped with a trap cover 9 for preventing leakage of drainage noise from a toilet or the like. In order to improve the sound insulation performance, the trap cover 9 has a surface of a cover body 9a made of solid iron or the like having a large specific gravity as shown in FIG. It is coated.

Here, the sound insulation effect in the uppermost dwelling unit of the apartment house having the drainage piping facility is as follows. First, since the average transmission loss of an iron plate (0.76 mm thick, areal density 5.86 kg / m ² ) is 28 dB, if the cast iron pipe + collecting pipe joint in Table 1 and the drainage flow rate 5.0 l / s, The noise that flows in is 52-28 = 24 dB.

[0008]

[Table 1]

As can be seen from Table 2, this numerical value becomes a very quiet indoor noise and has a sufficient sound insulation effect.

[0010]

[Table 2]

[0011]

[Effect of device]

 As explained above, according to the drainage piping system of the apartment house of the present invention, the drainage noise generated in the toilet is reduced by being silenced by the silencer, so that it is generated in the toilet on the top floor dwelling unit as in the past. It is possible to drastically reduce the generated drainage noise from leaking into the living room from the drainage port of the sink, and it is possible to obtain a very quiet living environment. In addition, since the trap cover is made of a solid and relatively important material, its sound insulation performance is enhanced, so that the drainage noise can be further reduced.
