Description of the Related Art In recent years, as shown in FIG. 3, a water supply unit (A) such as a water heater (10) and a water faucet (20) have been used for the construction of water around a building for heating and hot water supply. And a flexible fluid pipe (R), and the fluid pipe (R) is inserted into a flexible sheath pipe (S) and piped to the back of the wall (C), etc. ,
The so-called sheath tube method has become widespread. Such a construction method,
Free piping on the back of the wall (C) is possible, so less work is required compared to the previous piping method using metal pipes, and maintenance such as easy replacement of the fluid pipe (R) is possible. Has the merit that it can be easily performed.

を消すことができていた。However, in a plumbing system for water, when the water tap is used, if the valve is closed and the flow of water is suddenly stopped, the pressure in the pipe near the water tap suddenly increases, and the pipe returns. As a result, water collides with the inner wall of the pipe, causing a water hammer phenomenon in which sound is generated. In the above-mentioned 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 sheath pipe (S) has a soundproofing effect. I was able to mute that sound.

題が生じた。However, in such a sheath tube method,
As shown in FIG. 4, the fluid pipe (R) is flexible, so that when the flow of water in the pipe suddenly stops, the fluid pipe (R) undulates with the water hammer phenomenon. This collides with the inner wall of the sheath tube (S), and the fluid tube (R)
A new problem arises in that loud collision noise is generated between the tube and the sheath tube (S).

Can not do. Such a collision sound may cause discomfort to a person using the water tap, or may cause damage to the fluid pipe (R).

に消音構造を形成できる。According to the sound deadening structure of the present invention, the flow of water in the pipe suddenly stops and the pressure in the pipe sharply increases, and when the water returns, the water collides with the inner wall of the pipe. The buffer material prevents the flow of water in the pipe from suddenly stopping and the fluid pipe from waving, preventing the sound of collision between the fluid pipe and the sheath pipe, and generating sound. Can be completely eliminated.
In addition, since the cushioning material is in the form of a long sheet, a sound-absorbing structure can be formed at low cost.

In such a case, a cushioning material can be interposed in the space formed in such a case. In this case, the cushioning material is wound around the outer periphery of the fluid pipe in advance, or the fluid pipe and the cushioning material are further joined by an adhesive or the like. As compared with a case where these are inserted into the sheath tube after being integrated, the operation is simplified, and the buffer material can be easily interposed in the space between the fluid tube and the sheath tube.

衝突することによる損傷をひき起こすこともない。As described above, in the sound deadening structure of the present invention, the flow of water in the pipe is suddenly increased by interposing the cushioning material in the space formed between the fluid pipe and the sheath pipe. It is possible to effectively prevent the stoppage of the fluid pipe and the waving state of the fluid pipe, and the generation of collision noise between the fluid pipe and the sheath pipe. Therefore, the flow of water in the pipe suddenly stops and the pressure in the pipe sharply increases, and the return of the water prevents the water from hitting the inner wall of the pipe, thereby preventing the sound generated by the water hammer phenomenon. The buffer material prevents the flow of water from suddenly stopping and the fluid pipe becoming wavy, preventing the sound of collision between the fluid pipe and the sheath pipe from being generated, and completely eliminating the generation of sound. . As a result, the person using the water tap does not feel uncomfortable due to the collision sound. In addition, the fluid pipe does not cause damage due to collision with the sheath pipe.
