Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides sound insulation for pipes to prevent the sound of fluid flowing in pipes such as drainage pipes of buildings such as houses from being transmitted to living spaces and becoming noise. Regarding the cylinder.

[Prior Art] Conventionally, as a means of preventing the sound of fluid flowing through pipes such as tough water pipes in buildings such as houses from being transmitted to the living space, after the pipes are installed on site, the pipes are first wrapped in sound-absorbing material. The method used was to fix the sound insulator and then cover it with a sound insulating board formed from sheet metal on site.

[Problems to be Solved by the Invention] By the way, although the above-mentioned construction method has a soundproofing effect, since all construction is done on-site, it is very time-consuming and has extremely low construction efficiency.

Therefore, in the above conventional construction method, the present invention saves labor in the work of wrapping the sound absorbing material, forming the sound insulation board, and the work of the cover, which were all carried out on site, and makes it possible to efficiently perform soundproofing work on drainage pipes, etc. It is an object of the present invention to provide a sound insulating tube for piping.

[Means for solving the problems] The sound insulation tube for piping of the present invention for solving the above problems has the following features:
The sound-absorbing material is placed on the inside, and the sound-insulating plate is placed on the outside to form an integral body, and is formed into a slotted cylindrical shape to provide spring properties.

[Function] Since the sound insulating cylinder for piping of the present invention is constructed as described above, it is only necessary to seal the slotted part with tape at the piping construction site, so that the sound insulating tube for piping can be carried out efficiently. It can be carried out.

[Embodiment] An embodiment of the sound insulating tube for piping according to the present invention will be explained with reference to FIGS. , in this example, are colored iron plates, which are bonded together with an adhesive and formed into a slotted cylindrical shape to provide spring properties.

The sound absorbing material 1 inside the lengthwise one end 4 of the sound insulating tube 3 for piping having such a structure is cut to form a sound insulating pipe n3 to be connected.
The other end portion 5 is fitted. Further, the sound absorbing material 1 inside one end 6 in the circumferential direction of the sound insulating tube 3 for piping is cut so that the other end 7 in the circumferential direction can be wrapped.

The sound-absorbing material 1 inside the sound-insulating tube 3 for piping is provided with J slits 1-8 in the longitudinal direction so as to divide one section in the circumferential direction. 9 in the figure is a quarter portion.

Next, a case will be described in which the sound insulating cylinder 3 for piping constructed as described above is applied to a drainage standpipe 10 of a medium-to-high rise housing complex shown in FIG. 2. In the figure, 11 is a sewage side branch pipe from the toilet bowl 12 connected to the drainage standpipe 10, and 13 is a waste water side branch pipe also connected to the drainage standpipe 10. In such drainage piping, toilets 12) washbasins, bathtubs, etc.
When the appliance (not shown) is drained, the drain water flows into the side branch piping 11.13 and \'1. Pipe 10 pipe flow 0 included falls. As a result, the sound of falling wastewater is generated in the standpipe 10, and this sound of falling wastewater is transmitted through the standpipe 10 and surrounds the living space such as a living room, causing discomfort.

Therefore, the piping tube 3 having the above structure is coated on the standpipe 10, and the method of coating is as shown in FIG. teC
When formed into a letter shape and placed over the standpipe 10, the sound insulating tube 3 automatically restores its cylindrical shape due to its own spring properties, and the slotted portion 9 closes as shown in FIG. That is, the other @ part 7 in the circumferential direction enters into the inner side where the sound absorbing material 1 at one end 6 in the circumferential direction is cut, and the ends of the sound insulating plate 2 overlap. Then tape 14 at the seam of this wrapped part.
Paste and seal. Further, the sound insulating tube 3 has one end (upper end) 4 where the sound absorbing material 1 is cut in the vertical direction as shown in FIG.
Fit the inside of the sound insulating plate 2 to the other end (lower end) 5 of the upper sound insulating tube 3, wrap both upper and lower ends of the sound insulating plate 2, and apply tape 15 to the seam of this wrapped part to seal it. block

The drainage standpipe 10 covered with the sound insulating tube 3 in this way is
Transmission of the sound of falling water flowing through the standpipe 10 is reduced, and a soundproofing function is exhibited.

[Effects of the Invention] As can be seen from the above explanation, the sound insulating tube for piping of the present invention can be restored to a cylindrical shape and covered by simply opening the slotted portion against the spring force and covering the piping at the piping construction site. After that, all you have to do is seal the slotted part with tape.
Unlike conventional methods, there is no need to cut the sound absorbing material and sound insulating board one by one to match the pipe size on site, or to wrap them around the pipes individually, making soundproofing work for drainage pipes labor-saving and more efficient. It will be constructed.

In addition, the sound insulating tube for piping of the present invention has a structure in which the sound insulating plates at the joint portion in the circumferential direction and the connection portion when connected continuously in the vertical direction completely wrap, so that the sound insulation tube at the joint portion and the connection portion are completely wrapped. It is possible to suppress sound leakage from the ground, and has a better soundproofing effect than conventional construction methods.
