FIG. 5 is a front view showing a conventional floor panel. Conventionally, the floor panel 1 has a floor surface material (plywood, particle board, etc.) 7 on an upper surface of an extruded cement panel 5 having a plurality of hollow portions 3 or a solid ALC plate (not shown), and a tapping screw 9 or the like. It was configured by screw fixing. The floor panel 1 is placed and fixed between beams (not shown) to form an upper floor.

図ることを目的とする。However, in the conventional floor panel 1 described above, the surfaces of the floor surface material 7 and the extruded cement panel 5 are joined over the entire surface.
Although the sound due to conversation and the like can be effectively sound-insulated, the impact sound due to, for example, falling objects or the jumping of the upper floor, where the floor is a sound source, is directly transmitted from the floor surface material 7 to the extruded cement panel 5. The sound could not be isolated because it was transmitted to the lower floor. In particular, in the case of an ALC plate which is a solid member, the sound insulation performance could not be improved unless a composite structure with other members was used. In addition, rock wool,
If a sound absorbing material such as glass wool is filled, sound due to conversation and the like can be sound-insulated, but this has no effect on the above-mentioned floor impact sound and only increases the cost of the floor panel. The present invention has been made in view of the above circumstances, and provides a sound insulation floor capable of effectively reducing an impact sound to a lower floor side caused by a direct impact applied to a floor, and a sound insulation of the floor. It aims at improvement.

As the aggregate 21 of sandy grains, for example, silica sand mainly composed of quartz grains, fly ash collected from a flue of a pulverized coal combustion boiler of a thermal power plant, or the like can be used. The aggregate 21 of the sand-like particles is not limited to the above-mentioned silica sand and fly ash as long as the particles can freely move in the hollow portion 19 by the vibration energy given to the extruded cement panel 13.

和され、衝撃音が低減することになる。Next, the operation of the thus-configured sound insulation floor 11 will be described. When an object falls on the sound insulation floor 11 or a person jumps, an impact at that time is transmitted to the extruded cement panel 13 via the floor surface material 15, and the extruded cement panel 13 vibrates. When the extruded cement panel 13 vibrates, the particles of the aggregate 21 of the sand-like particles filled in the hollow portion 19 vibrate, and a part of the vibration energy for vibrating the extruded cement panel 13 is converted into particles of the aggregate 21. Will be absorbed as energy for vibrating. Therefore, by the absorption of this energy, the impact propagating to the extruded cement panel 13 is reduced, and the impact noise is reduced.

遮音性を向上させることができる。According to the sound insulating floor 11, since the aggregates 21 of the sand-like grains are filled in the hollow portion 19 of the extruded cement panel 13, the extruded cement panel 1 is formed by jumping or the like.
3 can be absorbed as the vibration energy of the particles of the aggregate 21, and the impact sound transmitted directly from the floor surface material 15 to the extruded cement panel 13 and transmitted to the lower floor side can be reduced. . As a result, it is possible to improve the sound insulation on the lower floor side of the impact sound generated when the impact is directly applied to the floor.

Further, since the hollow portion 19 is filled with the inorganic material, the fireproof performance can be improved. Furthermore, aggregate 2 of sandy grains
Since the effect can be obtained by filling the hollow portion 19 with 1,
An extruded cement panel 13 of the conventional standard can be used without increasing the thickness.

が好ましい。Next, another embodiment of the sound insulation floor according to the present invention will be described with reference to FIG. FIG. 2 is a front view showing another embodiment of the sound insulation floor according to the present invention. In the sound insulation floor 23, a plurality of rib-shaped joists 25, which are long in the front-rear direction of the panel, are provided on the upper surface of the extruded cement panel 13. The joist portion 25 is made of a material of the same quality as the extruded cement panel 13, which is integrally molded at the time of extrusion, a material of a different material integrally molded, or a material of the same or different material which is fixed after extrusion. There may be. In addition, in order to increase the load resistance, the joist portion 25 is preferably provided so as to protrude above the partition wall 27 that partitions the hollow portions 19 from each other.

Is placed. The floor surface material 15 is fixed to the joist portion 25 with a tapping screw 17. Therefore, the sound insulation floor 23 having the floor surface material 15 attached to the upper surface forms a gap 31 between the floor surface material 15 and the extruded cement panel 13. The sound insulation floor 23 is made of a floor surface material 15 and a joist 25.
When mounting and fixing to the device, a shock absorbing material (for example, a rubber plate or the like) may be interposed therebetween. With such a structure, the impact that propagates from the floor surface material 15 to the joist 25 can be reduced. Other structures are the same as those of the above-mentioned sound insulation floor 11.

As in the case of the sound insulation floor 11 described above, vibration energy due to jumping or the like is absorbed as vibration energy of the particles of the aggregate 21, and the impact sound transmitted to the lower floor side can be reduced to improve sound insulation. Since the joist portion 25 is provided, the contact area between the floor surface material 15 and the extruded cement panel 13 is reduced, and the impact is directly applied to the extruded cement panel 13.
This makes it difficult for the sound to be transmitted, which can also reduce the impact sound.
