播しやすいという問題があった。(Problems to be solved by the invention) However, according to the conventional floating floor, when a floor impact force is applied, the air in the air layer below the floor panel is rapidly compressed due to sinking or bending deformation of the floor panel, This compressed air acts as an air spring because there is no escape area below the floor panel, and a large reaction force acts on the floor panel to increase vibration of the floor panel. Further, there is a problem in that the above-mentioned air pressure acts on the floor base and the buffer under the floor panel, and as a result, the floor impact sound is easily propagated.
本発明は、このような浮床構造における床パネル下方の
空気圧の上昇による弊害を、床パネル自体の構造に改良

にある。(Means for Solving the Problems) In order to achieve the above object, in the present invention, a hollow panel is used as a floor panel for a floating floor, and the hollow portion of the hollow panel is used to remove compressed air below the floor panel. It is to diffuse once in the hollow portion, and then discharge and diffuse from the hollow portion to the panel surface.

めの空気導入孔が設ける構成としたものである。Specifically, the solution means taken by the present invention is intended for a floor panel for a floating floor, which is placed on a floor base material while being elastically supported via a buffer such as a glass wool mat and with an air layer interposed. And The floating floor panel comprises a hollow panel having a proper number of hollow portions inside, and a groove forming an air flow passage for laterally flowing air is formed on the panel surface directly above the hollow portion of the hollow panel. Etc., and the bottom of the recess is provided with an air discharge hole for communicating the air flow passage with the hollow portion, and the lower surface of the panel communicates the air layer with the hollow portion. The air introduction hole is provided to reduce the pressure.

When the air pressure in the hollow portion further rises, the air pressure is discharged from the upper air discharge hole to the recess on the panel surface and is diffused to the panel surface along the air flow passage formed by the recess on the panel surface. As a result, the increase in air pressure below the floor panel is instantaneously reduced to a small level.

気の吸入・排出がなされる。Further, in this case, since the compressed air that locally rises in pressure under the floor panel is once diffused in the hollow portion, even if the air introduction hole on the lower surface of the panel has a small diameter, uniform air can be introduced. There is no reduction in the rigidity of the floor panel.
Further, the compressed air introduced from the air introduction hole expands in the hollow portion, its flow resistance decreases, and is rapidly diffused. At the same time, the compressed air below the floor panel can be quickly taken into the hollow portion, and the air below the floor panel is instantaneously sucked and discharged.

を有効に低減することができる。Therefore, in the above-described embodiment, when the impact force P is applied to the floor surface as shown in FIG. 1, the impact panel P bends and deforms the floor panel A, and sinks by the amount of the compressive strain of the buffer body 2. The air in the air layer 4 below it is compressed, but this compressed air not only escapes laterally between the supports 3, but also the hollow portion 1 is formed on the lower surface of the hollow panel 11 as shown in FIG.
Hollow part 1 through an air introduction hole 16 communicating with 0 and opening.
It flows into 0 and is diffused. Further, when the air pressure in the hollow portion 10 rises, it flows out of the hollow portion 10 through the air discharge hole 15 into a recess on the panel surface, and then laterally along the air flow passage 12 formed by the recess on the panel surface. Diffused in the direction.
As a result, the air pressure of the air layer 4 below the floor panel A is rapidly reduced, and the movement (compression / expansion force) of the air acting vertically in the air layer 5 is reduced as in the conventional case.
The impact force is generated through this air pressure and impact body 2 below floor panel A
Also, the transmission to the floor base 1 is reduced, and the transmission of the reaction force of the air pressure to the upper floor panel A is reduced. Thereby, the vibration of the floor base 1 is suppressed, and the bending vibration and the vertical vibration of the floor panel A are reduced, and the synergistic effect can effectively reduce the propagation of the floor impact sound to the downstairs. .

遮音性能を得た。(Experimental example) Next, specifically, a floor panel having a width of 909 mm and a length of 18
Prepare a wooden hollow panel with a thickness of 18 mm and a thickness of 52 mm. This hollow panel is a 20mm thick particle board with 2mm deep and 20mm wide concave grooves crossed vertically and horizontally at a pitch of 40mm. As the material, about 30 wooden splints each having a thickness of 12 mm and a width of 20 mm are arranged between the both side materials at intervals of 40 mm and arranged in parallel along the short side direction and bonded with an adhesive. Furthermore, a diameter of 10 mm is provided at the bottom of the groove on the hollow.
300 air discharge holes are uniformly formed over the entire panel, and the back surface material is provided with air introduction holes communicating with the hollow portion with the same diameter and the same number as the air discharge holes.

A plurality of 0 mm plywood supports are arranged side by side at a 450 mm pitch, a plurality of the above hollow panels are placed, and a 12 mm thick wood floor material is used to finish the floor to create a floating floor. On the other hand, when a floor impact sound was measured from the downstairs by applying an impact force with a heavy impact sound generator specified in JIS-A1418, the sound insulation performance as shown by the line A in FIG. 18 was obtained.

されることが判明した。As is clear from FIG. 18, the sound insulation performance of the comparative example is L-
The performance is about 60, which is a level up to the point where the floor impact sound is heard to be "worrisome", whereas in the embodiment of the present invention, the sound insulation performance is reduced to L-47, and the floor impact sound is "almost noticeable". It was found that the vibration of the floor panel is large in the comparative example and easily propagates to the floor substrate in the comparative example, whereas the noise of the floor substrate is significantly improved in the examples of the present invention. .

することが可能である。(Effects of the Invention) As described above, according to the floor panel for a floating floor of the present invention, when a floor impact force is applied, the air layer below the floor panel is compressed in response to bending deformation or sinking of the floor panel. Since the air can be instantaneously smoothly discharged and diffused to the panel surface, the increase in the air pressure below the floor panel can be instantaneously suppressed to a small level, and vibration caused by the reaction force of the air pressure of the floor panel and the floor base of the air pressure can be suppressed. It is possible to reduce the transmission of the impact force due to the action on the floor impact noise and to reduce the floor impact sound emitted downstairs.

ものとすることができる。Further, the floor panel of the present invention is a hollow panel, and since the air introduction hole communicates with the hollow portion of the hollow panel, the resistance when air passes through the inside of the panel is small and the compressed air can be quickly discharged. . Moreover, since the air flow passage formed by the recess is provided on the panel surface and the air discharge hole is opened at the bottom of the recess, even if the floor finishing material is provided on the floor panel, the air discharge hole is blocked. The air discharged on the upper surface of the floor panel can be smoothly diffused in the lateral direction. As a result, the effect of suppressing the increase in air pressure can be ensured.
