  Further, it goes without saying that the noise / vibration reduction plate between the layers of the building can be arranged vertically so as to be applied to a wall separated from the next.

  The operation of the present invention will be described with reference to FIGS. 3 and 4 as follows.

  First, the noise / vibration generated in the upper layer starts to be transmitted through the bottom of the room, and the noise / vibration thus transmitted is first absorbed by the upper rubber pad layer 1300.

  The remaining vibration components after being absorbed are transmitted through the plastic plate 1210 and the plastic column 1220. At this time, the vibration generated in the plastic column 1220 is a sound-absorbing vinyl tube in contact with the plastic column 1220. Is transmitted to 1230 and absorbed and exhausted therein.

  The remaining noise / vibration is absorbed by the nonwoven fabric 1240 and continuously absorbed by the lower rubber pad layer 1100.

  With such a structural and material structure, the vibration and sound insulation effect is realized almost completely.

<Test example>

  4, in the structure according to FIG. 4, only the intermediate sound insulation layer 1200 excluding the upper rubber pad 1300 and the lower rubber pad 1100 is tested, and the plastic is a reinforced plastic mixed with PC and PBT. . And the comparative example made the reinforced plastic board which mixed PC and PBT the object material.

  In the intermediate sound insulation layer of the present invention, the plastic plate was formed in a width of 17 cm × 20 cm, a thickness of 1 cm, and a distance of 3 cm. The diameter of the plastic column was 1.5 mm.

  The thickness of the nonwoven fabric was set to 1 cm, and the diameter of the vinyl tube was set to 1 cm.

  On the other hand, the board to be tested was surrounded by a sound absorbing film 1700, and the noise measuring instrument 1900 was placed at a position 10 cm below the board.

  Then, a wooden ball 1600 having a weight of 5.6 g was dropped from a height of 50 cm, and the noise that passed through the board was measured.

  The noise measurement time at this time is 1 minute, and the measured values are as follows. Here, MaxP indicates the maximum noise value, and Leq indicates the equivalent noise value.

  As a result of the test, a large noise reduction effect was obtained. If a rubber pad is additionally applied, a greater noise blocking effect will be obtained.

  According to the present invention configured as described above, it is possible to absorb almost all the noise and vibration transmitted down through the sound-absorbing vinyl tube, so even if an intermediate material is used, an expensive material is used. There exists an advantage that there exists the above effect.
