【発明の詳細な説明】 （産業上の利用分野） 本発明は、建築物内の暖房、給湯等の水まわりの施工
に用いられる流体管の二重配管における消音構造の組付
方法に関する。Description: TECHNICAL FIELD The present invention relates to a method of assembling a sound deadening structure in a double pipe of a fluid pipe used for surrounding water such as heating and hot water supply in a building.

がかからず、また、流体管（Ｒ）の更新が容易である等
メンテナンスが簡単に行なえるというメリットを有して
いる。(Prior art) In recent years, as shown in FIG. 3, for the heating of buildings and construction around water such as hot water supply, as shown in FIG. 3, a water supply unit (A) such as a water heater (10) and a water tap (20), etc. The used portion (B) of the above is connected with a flexible fluid pipe (R), and the fluid pipe (R) is inserted into a flexible sheath pipe (S) to be piped to the back wall (C) or the like. The so-called sheath pipe construction method has become popular. Since this construction method allows free piping under the wall (C), it requires less labor than the piping method using metal pipes performed before that, and the fluid pipe (R) can be easily renewed. This has the advantage that maintenance can be performed easily.

により発生した音に対しては、流体管（Ｒ）が鞘管
（Ｓ）内に保護されているため、鞘管（Ｓ）による防音
効果によって、その音を消すことができていた。In the above sheath pipe construction method, since the fluid pipe (R) is protected in the sheath pipe (S) against the sound generated by such a water hammer phenomenon, the sound insulation effect of the sheath pipe (S) causes I was able to turn off the sound.

問題が生じた。However, in such a sheath pipe construction method, as shown in FIG. 4, since the fluid pipe (R) is flexible, when the flow of water in the pipe suddenly stops, the fluid pipe (R) is accompanied by a water hammer phenomenon. (R) creates a wavy state, which collides with the inner wall of the sheath tube (S) and causes the fluid tube (R) to
A new problem arose that a loud collision sound was generated between the sheath tube and the sheath tube (S).

体管（Ｒ）の損傷を招いたりする。Such a collision sound is mainly generated in the curved portion of the pipe by rubbing the fluid pipe (R) against the inner wall of the sheath pipe (S), and cannot be prevented by the soundproof effect of the sheath pipe (S) like a water hammer. . Then, such a collision sound makes a person who uses the water faucet uncomfortable and causes damage to the fluid pipe (R).

A method of assembling a sound deadening structure for silencing a collision noise between a fluid pipe and a sheath pipe that occurs with a water hammer phenomenon in a double pipe of a fluid pipe to be installed as a pipe. By inserting the fluid pipe into the sheath pipe while winding the cushion sheet-shaped cushioning material, the cushioning material is interposed in the space formed between the fluid pipe and the sheath pipe.

Since a cushioning material is interposed in the space formed between the pipe and the cushioning material winding operation and insertion operation into the fluid pipe are performed simultaneously, the cushioning material is wrapped around the fluid pipe in advance. After that, or as compared with the case where the fluid pipe and the cushioning material are joined and integrated with an adhesive or the like and then these are inserted into the sheath pipe, the work is simplified and the cushioning material is easily attached to the fluid pipe and the sheathing material. It can be interposed in the space between the tubes.
また、緩衝材は長尺シート状を使用しているので、安
価に消音構造を形成できる。Further, since the cushioning material is in the form of a long sheet, the sound deadening structure can be formed at low cost.

る。And, the sound deadening structure assembled by this assembly method is caused by a water hammer phenomenon in which the flow of water in the pipe suddenly stops and the pressure in the pipe rapidly increases, and by the return, water collides with the inner wall of the pipe. In addition to preventing the generation of sound, the cushioning material prevents the flow of water in the pipe from suddenly stopping and causing the fluid pipe to become wavy, and prevents the collision noise between the fluid pipe and the sheath pipe from occurring. Can be completely eliminated.

Therefore, the flow of water in the pipe suddenly stops, the pressure in the pipe rapidly increases, and the return of the water collides with the inner wall of the pipe to prevent the generation of sound due to the water hammer phenomenon. The buffer material (1) prevents the flow of water from suddenly stopping and causing the fluid pipe (R) to become wavy, and prevents the collision noise between the fluid pipe (R) and the sheath pipe (S) from being generated. However, the generation of sound can be completely eliminated. As a result, the person using the faucet does not feel uncomfortable due to the collision noise. Further, the fluid pipe (R) will not be damaged by colliding with the sheath pipe (S).
