撃音に対する遮音性能の改善が要望されていた。(Conventional Technique #@) Conventionally, as a double floor, multiple support bolts are attached to the floorboard, and an elastic body (
It is generally known that a rubber pedestal (rubber pedestal) is attached, which is laid out on a floor base, and a floor finishing material is placed on the floor board. However, with such a double floor, the impact force during heavy floor impact vibration is large, so the rebound of the elastic body (
Since the vibration of the floorboard is large and difficult to attenuate, its sound insulation performance is compared to the sound insulation performance of the floor base in the frozen field (state II where there is no finish on the floor base).
LH-55) was always inferior. For this reason, there has been a demand for improved sound insulation performance against heavy floor impact noise.

As disclosed in Japanese Patent No. 59-173456, the above-mentioned floorboard or the flooring material to be placed on the floorboard is formed by forming a plurality of cavities between two boards (by providing a space material, and filling the cavities with polyurethane foam). A double floor using a sound insulating flooring material equipped with a panel-shaped dynamic vibration absorbing material with a weight board of thick steel plate attached to one side of the spring material of the cape, and as disclosed in Japanese Patent Publication No. 58-47546. , Support?# A method has been proposed in which the physical properties of the rubber of the rubber elastic body at the bottom of the leg are specified.

い間罷点がある。(Problem to be Solved by the Invention 11) However, in the case of the double floor described in Patent Publication If! Since it is formed by attaching a flannel-shaped dynamic vibration absorbing material inside the nine cavities, the process is difficult and time consuming, and the thickness of the floor becomes even larger, which tends to impair the vibration damping effect. In addition, in the case of the double bed described in Japanese Patent Publication No. 58-47546, although the physical properties of the rubber of the rubber elastic body have been improved, it is difficult to avoid problems with large impact forces such as weight impact sources. The drawback is that the rubber elastic body turns into a solid solid that is a good conductor of vibration before the impact, so it cannot be expected to be particularly effective in reducing low-frequency sounds.

性能が向上する急様を選定しうる。Once compressed and deformed, an elastic body rebounds to return to its original shape due to its elasticity. This rebound effect is suppressed by the weight of the weight, and the weight of the weight is applied to the elastic body, thereby shifting the natural frequency of the double bed to a lower frequency range. Shock vibrations are suppressed in the region above this natural frequency, so select an appropriate weight of the weight depending on the load on the floor and the elastic body. The wave number slope can improve the sound insulation performance of coulometric floor impact sound. In addition, depending on the shape and dimensions of the double floor,
By changing the mounting position of the support leg and weight, and the method of fixing the weight, it is possible to select the configuration that will most improve the sound insulation performance.

Alternatively, since the support leg is mounted on a receiver at an arbitrary position via a cushioning seat plate, the sound insulation performance of the floor base against heavy floor impact noise in frozen fields can be easily improved. In addition, since the weight is simply attached to the support #, there is no loss of workability and construction can be done quickly and easily. Installation can be done economically.
