Taking these conventional problems into account, the inventors of the present invention conducted various experiments. So As a result, it was previously known that the sound insulation performance would not deteriorate if the finishing material was soft. In addition to being soft, it is also important to use a relatively soft material for the base layer. For example, it was found that it has excellent sound insulation performance against light impact sound. However, if you put furniture Regarding the pressure resistance performance caused by walking, the amount of distortion will be too large if a soft material is used. , its performance deteriorates. In other words, there is a contradictory relationship between light impact sound insulation performance and pressure resistance performance. It's in charge. In addition, simply using a soft material for the base layer improves the sound insulation performance of lightweight impact sounds. However, the sound insulation performance for weight impact sound tends to deteriorate due to resonance. Ru.

0010 Figure 1 shows the concrete structure of the frame structure according to the present invention as a floor structure of a concrete building. A longitudinal cross-sectional view of the state in which it is opened is shown. 1 in the figure is the structure of a concrete building. Horizontal slab, 2 is a plate-shaped cushioning material installed using adhesive on top of it, 3 is on top of it A plate-shaped base material was also laid on the surface using adhesive, 4 is for providing a heavy base layer 5. The mortar dumplings are scattered almost regularly on top of the mortar dumplings. A plate-shaped base material that was leveled and laid before conversion, 7 is a base material 6 with adhesive and Wood material such as natural wood composite flooring installed by using nailing together with the provided mounting member 8 It is a plate-shaped finishing material made of various materials.

Here, the cushioning material 2 is made of foamed polyolefin resin such as urethane foam, foamed polypropylene, foamed polyethylene, glass wool, rock wool, natural rubber, synthetic rubber, foamed natural rubber, foamed synthetic rubber, etc. It is a soft or relatively soft material that can be elastically deformed. The cushioning material has a 5% strain compressive strength of 0.01 to 0.1 Kg/cm ² , preferably 0.02 to 0.05 Kg/cm ² , and a compressive modulus of 5×10 ⁴ N/m ² to 5× 10 ⁵ N/m ² , preferably within the range of 1 to 2 × 10 ⁵ N/m ² , and furthermore, the spring constant is 2.0 × 10 ⁷ N/m・m ² or less, preferably 1 to 8 × 10 ⁶ N/m 2 Those within the range of m・m ² are used. If this 5% strain compressive strength is less than 0.01Kg/cm ² , the pressure resistance will be poor, and if it exceeds 0.1Kg/cm ² , the sound insulation performance for heavy impact sound will be poor, and the sound insulation performance for lightweight impact sound will be poor. The performance improvement effect becomes smaller.

Further, the base materials 3 and 6 have higher rigidity than the cushioning material 2 and are hard or semi-hard, and their 5% strain compressive strength is, for example, 0.5 Kg/cm ² or more. Suitable and usually a foamed synthetic resin body such as plate-shaped expanded polystyrene or other plate-shaped urethane foam of the same type as conventional base materials, or a non-foamed synthetic resin body such as plate-shaped polystyrene, polypropylene, polyethylene, vinyl chloride, etc. is used. The thickness of each of these layers is preferably within the range of 25 to 95 mm.

A heavy base layer 5 consisting of mortar balls 4 with a thickness of 10 mm and a weight of 20 kg/ ^m2 , a base material 6 consisting of a 40x molded polystyrene foam with a thickness of 25 mm, and a finish consisting of natural wood composite flooring with a thickness of 12 mm. In the case of the floor structure with material 7, it was LL-50 and LH-55. Moreover, when urethane foam with a thickness of 30 mm and a 5% strain compressive strength of 0.03 kg/cm ² was used as the cushioning material 2, the results were LL-45 and LH-55. On the other hand, on a horizontal slab with a thickness of 150 mm, a mortar dumpling with a thickness of 10 mm and a weight of 20 kg/ ^m2 , a base material made of a 40 times expanded polystyrene molded product with a thickness of 50 mm, and a finishing material made of a natural wood composite flooring with a thickness of 12 mm are placed in order. In the case of a conventional floor structure with wood, it was LL-70 and LH-55. Further, as shown in Fig. 4, on top of the 150 mm thick horizontal slab 1, mortar balls 4 with a thickness of 10 mm and a weight of 20 kg/m ² , a base material 3 made of a 40 times expanded polystyrene molded product with a thickness of 25 mm, and a base material 3 with a thickness of 20 mm are placed in order. A cushioning material 2 made of urethane foam with a 5% strain compressive strength of 0.03 Kg/cm ² , a base material 6 made of a 40x molded polystyrene foam with a thickness of 25 mm, and a finishing material 7 made of natural wood composite flooring with a thickness of 12 mm. In the case of the installed floor structure, the sound insulation performance for weight impact sound decreased in LL-50 and LH-60. This result also shows that the floor structure according to the present invention has excellent sound insulation performance for lightweight impact sounds without any loss in sound insulation performance for heavy impact sounds.

[0015] Next, FIG. 2 shows another embodiment of the floor structure according to the present invention. Here, water A plate-shaped cushioning material 2 is provided on the flat slab 1 with a space 9 left between the side edges, and this is attached to the base material 3.
