This invention relates to a floating floor structure with excellent sound insulation performance.

であつた。(Prior art) Floor impact noise is caused by the impact force caused by people walking, jumping, etc. that causes the floor structure to vibrate, and the vibrations emit sound to the lower floor. be. This floor impact sound includes the floor impact sound caused by a light impact force such as when a person walks, and the weight impact sound caused by a child jumping (effective impact force of 3875N in a heavy floor impact sound generator specified in JIS-A1418). There is a floor impact sound caused by the corresponding impact force). Among the floor impact sounds mentioned above, those caused by light impact force can be reduced by absorbing the impact force by using floor finishing materials such as carpets, but those caused by weight impact force have a large impact force and can be reduced under the floor. This vibration is easily transmitted to the ground and causes the subfloor itself to vibrate, making it difficult to reduce the vibration.

うにしたものである。 A floating floor structure is known as a floor structure for reducing such floor impact noise. This conventional floating floor consists of a glass wool cushioning layer placed on a concrete floor slab, a floor panel material placed directly on top of it, and a floor finishing material such as carpet or wood floor placed on top of that. Alternatively, as shown in FIG. 13, a support c such as a joist material is placed on the buffer material layer b on the concrete floor slab a, and a floor panel material d is placed on top of the support material c between the buffer material layer b and the buffer material layer b. air layer e
There is also a floor finishing material f which is placed on the concrete floor while holding it, and in both cases, the shock force is prevented from being directly transmitted to the concrete floor slab a due to the cushioning properties of the glass wool cushioning material layer b. It is designed to prevent this.

ある。 According to the above-mentioned conventional floating floor structure, in the former one in which the floor panel material is placed directly on the cushioning material layer, when floor impact force acts, the floor panel material bends and deforms, and the impact force is applied to the cushioning material layer. It becomes concentrated,
It is transmitted to the floor slab without much absorption or relaxation in the buffer material layer, resulting in poor cushioning properties. On the other hand, in the latter case, in which the floor panel material d is placed on the cushioning material layer b via the support c, the impact force P is dispersed by the support c, as shown in FIG. transmitted to layer b,
This dispersion force P1 is absorbed and relaxed by the cushioning material layer b, so that the impact force applied to the floor slab a is reduced and dispersed, and the floor impact noise emitted downstairs is reduced. Compared to the case without it, the floor impact sound is lower overall, and the sound insulation grade based on the floor impact sound level according to the Architectural Institute of Japan standards is L-55, so please be careful as the sound caused by impact is a little bothersome in daily life. It is possible to reduce floor impact noise to a level where it does not become a problem if you live with it.
（発明が解決しようとする課題）
しかしながら、近年、プライバシーの尊重と住
宅の高層化に伴つて、さらに優れた遮音性能が要
求されており、上記従来の浮床構造では、Ｌ−55
の性能までが限界であり、遮音等級としてＬ−50
やＬ−45という、床衝撃音がほとんど気にならな
い範囲まで低減することは困難であつた。(Problem to be solved by the invention) However, in recent years, with respect for privacy and the rise in the height of residential buildings, even better sound insulation performance has been required.
The performance is limited to L-50 as a sound insulation grade.
It was difficult to reduce the floor impact noise to a level where it was hardly noticeable, such as the L-45 and the L-45.
その理由について考察するに、上記従来の浮床
構造では例えばJISで規定するところの3875Nと
いう大きな衝撃力が作用すると、第１３図に示す
如く瞬間的に大きな曲げ変形を生じて、床面に大

ブａに対して上記周波数の振動が付加されてしま
い、その結果階下への放出音が大きくなつて床衝
撃音レベルが基準値を満足出来なくしているもの
と推定される。 Considering the reason for this, when a large impact force of 3875N as specified by JIS is applied to the conventional floating floor structure mentioned above, for example, a large bending deformation occurs instantaneously as shown in Figure 13, resulting in large bending of the floor surface. Vibration occurs. The vibration frequency of this bending vibration changes depending on the size of the floor panel material d and the spacing of the supports c placed below it, but the larger the vibration is, or the longer the vibration continues, the more the It is presumed that vibrations of the above frequency are applied to the slab a, and as a result, the sound emitted downstairs becomes louder, making the floor impact sound level unable to satisfy the standard value.

る。 Furthermore, in a floating floor structure in which a support body c is disposed on a cushioning material layer b, when the floor panel material d is bent and deformed due to a floor impact force, the air between the floor panel material d and the cushioning material layer b is The air in layer e is compressed as its flow is blocked by support c, and part of this air pressure escapes laterally between supports c and c, but part of it acts vertically as an air spring. A force P' is transmitted to the floor slab a via the buffer material layer b, and the reaction force of this air pressure from the buffer material layer b acts on the floor panel material d, causing bending vibration in the floor panel material d. . In other words, it is estimated that the vibrations of the floor slab a and the floor panel material d are amplified due to the compression and expansion forces acting on the air layer e, and the floor impact sound is amplified.

This reduces not only bending vibrations on the floor material surface, but also vibrations in the subfloor itself, achieving sound insulation performance higher than the floor impact sound level L-55, which was the limit of conventional floating floor structures, such as L-50. The purpose is to demonstrate the sound insulation performance of L-45 etc.

せることが可能である。(Function) With the above configuration, in the first to third inventions of the present application, when an impact force is applied to the floor surface, this impact force is dispersed by the cushioning material and transmitted to the floor base, and the cushioning material is compressively deformed. It is effectively absorbed and alleviated by At the same time, the panel material bends and deforms due to the above-mentioned floor impact force, compressing the air in the air layer below it, but this compressed air not only escapes laterally, but also passes through the ventilation holes on the sides of the panel material. Or, since it flows out from the top surface, the action of air acting perpendicularly to the bottom surface of the panel material in this air layer, that is, the compression and expansion force, is rapidly reduced, and this reduces the force transmitted to the subfloor via air pressure and this The force transmitted to the panel material as a reaction force of air pressure is reduced, and bending vibration of the flooring and panel material is reduced. Therefore, the propagation of the floor impact sound generated by the vibration of the subfloor to the lower floors is effectively reduced, and high sound insulation performance such as L-50 and L-45, which was difficult to achieve with conventional dry floors, is achieved. It is possible to demonstrate this.

At the same time, the panel material 3 bends and deforms due to the floor impact force P, and sinks by the compressive strain of the cushioning material 2, compressing the air in the air layer 5 below. In addition to escaping laterally between the materials 2 and 2, the inside of the panel material 3 also escapes through the ventilation holes 7 that are opened on the bottom surface of the panel material 3 so as to communicate with the air layer 5, as shown in FIG. 8 or 9. (Hollow hole 4) and flows out from the side surface or both the side surface and the top surface, and the air pressure in the air layer 5 sandwiched between the cushioning materials 2, 2 decreases quickly.
Air movement acting in the vertical direction (compression/expansion force)
is reduced, and the transmission of the impact force to the flooring 1 below the panel material 3 via this air pressure is reduced, and the transmission of the reaction force of this air pressure to the panel material 3 above is reduced. As a result, the vibration of the floor subfloor 1 is suppressed, and the bending vibration and vertical vibration of the panel material 3 are reduced, and this synergistic effect can effectively reduce the propagation of floor impact sound downstairs. .

しく低減できるものである。 As is clear from FIG. 12, in the example of the present invention,
Even though the hollow panel is placed on a cushioning material, when the air layer below the hollow panel is subjected to impact compression, the side surface (or both the side surface and the top surface) may be damaged through the hollow part of the panel. Since the compressed air pressure is discharged almost simultaneously when an impact force is applied, the compressed air pressure decreases, reducing the impact force being transmitted directly to the lower part of the hollow panel via the air pressure, and also reducing the air pressure reaction. It can be seen that the bending vibration of the hollow panel due to force is also reduced, and that it is possible to significantly reduce passing sound, especially in the 63Hz frequency band. Therefore, in the example of the present invention, the sound insulation grade is reduced to L-44, and the floor impact sound can be significantly reduced to "not noticeable" or "to be heard from far away."

有する。(Effects of the Invention) As explained above, according to the floating floor structure of the first to third inventions of the present application, when a floor impact force is applied, the air pressure in the air layer below the panel material is instantly applied to the side surface of the panel or the top surface of the panel. This reduces the transmission of impact force to the subfloor via the air pressure and the promotion of bending vibration of the panel material due to the reaction force of the air pressure, thereby reducing the vibration of the subfloor itself and the panels. The bending vibration of the material is reduced, the vibration of the subfloor is reduced, the emission of floor impact noise is small, and excellent sound insulation performance can be achieved. In addition, the reaction of the floor panel itself is small, and vibrations on the floor surface are quickly stopped, reducing the impact on the legs and hips when walking or running on the floor. Therefore, it is possible to provide a floor structure suitable for a high-rise building or a floor structure for various sports facilities. moreover,
The flow of air under the floor reduces the accumulation of moisture and prevents condensation under the floor.
