There is. Therefore, the support in the stubbin cone (7) is a point joint (
9) For example, first, the deck (6) and the noise generating section I [compartment (6) are transported and installed on a single arm, and then transported and installed together with the single residential section (3) ''+accommodation skid base 0). The implementation is just a matter of course.

るものである。The simple diagram shows that the stubbin cone (7) has a structure O point connection (9) and the other implementation side, and the stubbin cone (70 tip) is located a little deeper inside the noise source compartment side.
A recess (b) having a conical recess is formed, and the stubbin cone (7b) on the residential section side has a smaller diameter than the stubbin cone (Ym) on the noise generating section side, and its lower end fits into the recess box. It is formed into a truncated conical convex part. Then, as shown in the figure, concrete (2) is filled between the concave part ■ and the convex part C@ and corresponding to the conical part C@ of the convex part HO1iii1, and noise is generated as shown in the figure. Mortar 4 is injected to fill the gap between the inner surface of the end of the source section m side stubbin cone (mayJc) and the lower end outer corner of the residential section side stubbin cone (τk). The difference is that this 0@degree change #:lf:Yoru II! reduces the amount of noise energy transmitted, similar to the hard rubber trout shown in the figure.
