In the flooring material described in Japanese Patent Publication No. 17, a soft high-foaming layer having an expansion ratio of 3 to 10 times and a soft low-foaming layer having an expansion ratio of 1.5 to 3 times to be embossed are sequentially laminated on the back surface of the flooring body. Become. The flooring material described in Japanese Utility Model Laid-Open Publication No. 61-47339 has a sound insulation foam composed of a plurality of layers attached to the entire lower surface of a wooden board, and the foaming ratios of adjacent upper and lower layers are different from each other. It is assumed. The composite of foams having different expansion ratios as in the prior art functions as a cushioning material that gives a buffering effect by deformation when subjected to an impact force, and is performed through deformation because of its low rigidity. The buffer time becomes longer. Therefore, even though the momentum change, that is, the time integral of the impulse and the impact force is constant, the peak value of the impact force and the natural frequency of the impact are reduced, the energy input to the substrate is reduced, and the sound due to the impact is reduced. And vibration can be reduced. Further, when these cushioning materials are combined with the back surface of a building material such as a floorboard, energy of an impact force is absorbed through expansion and contraction of the cushioning material caused by bending vibration of the building material.

感が悪化する等の問題をもたらしていた。The soundproofing function is greatly affected by the thickness ratio between the building material and the cushioning material. To improve the soundproofing function, the thickness ratio of the cushioning material to the building material must be 2 to 2.
Must be tripled. However, if the thickness of the composite foam in the above-mentioned conventional soundproof floorboard is in such a range, the cushioning material becomes too thick, and the entire floorboard becomes excessively bent. For this reason, there have been problems such as breakage at the connecting portion of the floorboard and deterioration of walking feeling due to excessive sinking.

The present inventor has conducted extensive research to solve the above-mentioned problems of the prior art, and has completed the present invention.

より一層の向上に寄与する。As the floor board substrate, plywood, particle board, hard board, LVL (parallel plywood) or the like can be used as needed. When a synthetic resin foam sheet having an excellent buffer effect is sandwiched between the substrates, the soundproofing effect can be improved. Further, by forming a back groove on the back surface of the substrate, the rigidity of the substrate can be reduced, and the impact energy applied to the surface can be absorbed in the substrate, and a part of the substrate is divided by the back groove. As a result, the transmission of sound is hindered, and the soundproofing effect is further improved.

As the makeup, a method such as laminating and bonding a surface decorative material such as a veneer, a synthetic resin or a synthetic resin foam decorative sheet, decorative paper or a synthetic resin impregnated decorative paper, or printing a pattern after applying an undercoat. Is exemplified.

吸収される。On the back surface of the substrate, an open-cell foam synthetic resin sheet and a closed-cell foam synthetic resin sheet are sequentially laminated and bonded as a cushioning material. By selecting an open-cell foam as the foamed synthetic resin sheet directly adhered to the back surface of the substrate, the energy applied from the front surface is simply absorbed by the synthetic resin itself constituting the foamed synthetic resin sheet. Instead, it is effectively absorbed by the viscous resistance of the gas entering and exiting the porous body as it deforms, that is, air damping.

When it is less than 40 times, the ability to absorb the energy applied from the surface becomes insufficient, and when it exceeds 60 times, the sheet becomes too soft although the energy absorbing ability is excellent, and the compressive strength against the load applied from the surface becomes sharp. ,
It is not preferable because only a slight load is applied and it contracts. The resin used as the foamed synthetic resin sheet is not particularly limited as long as it forms an open cell type.
Specific examples include polyurethane, polyvinyl chloride, polyvinyl alcohol, natural rubber, and synthetic rubber.

示される。A closed cell foam is selected as the second foam synthetic resin sheet laminated and adhered to the back side of the open cell foam synthetic resin sheet. The expansion ratio is preferably 20 to 30 times. By making the expansion ratio smaller than the expansion ratio of the open-cell type synthetic resin sheet and the foaming mode different from that of the closed-cell type, the function of absorbing impact energy is slightly impaired, but the strength against the compressive load is reduced. Can be increased. That is, when the energy applied from the surface cannot be sufficiently absorbed by the open-cell type synthetic resin sheet, it can be absorbed by the closed-cell type synthetic resin sheet. If the expansion ratio of the closed-cell foam synthetic resin sheet is less than 20 times, the sheet becomes hard, and the energy that cannot be absorbed is directly transmitted downstairs, so that the soundproofing performance is reduced. On the other hand, if the expansion ratio exceeds 30 times, the sheet becomes too flexible,
The sink due to the expansion and contraction of the cushioning material composed of the two foamed synthetic resin sheets increases, and when walking, the floor surface is too soft, which causes anxiety and fatigue, which is not preferable. The synthetic resin used as the closed cell foam synthetic resin sheet is not particularly limited as long as it forms a closed cell foam. Specifically, polyethylene, polypropylene, polyurethane, polystyrene, vinyl chloride and the like are exemplified.

効果が向上する。On the front and back surfaces of the closed-cell type foamed synthetic resin sheet constituting the backmost layer, a large number of projections preferably having an arbitrary shape are formed. Thereby, a large number of air chambers are formed on the bonding surface with the open-cell foam synthetic resin sheet, and a large number of air chambers are formed on the bonding surface with the floor substrate when the floorboard is constructed on the floor substrate. The presence of these air chambers further improves the soundproofing performance and improves the effect of preventing sound from propagating downstairs.
