Description
【考案の詳細な説明】 〔技術分野〕 本考案は、軽量床において衝撃に伴って発生する音をで
きるだけ小さくするための下地材に関する。[Technical Field] The present invention relates to a base material for reducing noise generated by impact on a lightweight floor as much as possible.
従来、軽量床において、衝撃に伴って発生する音を小さ
くするための下地材としては、発泡ポリエチレン、発泡
ポリウレタン、発泡ゴムなどの発泡体シートが使用され
ていた。Conventionally, in a lightweight floor, a foam sheet such as foamed polyethylene, foamed polyurethane, or foamed rubber has been used as a base material for reducing the sound generated due to impact.
しかしながら、これら発泡シートのみでは、衝撃音を防
止するのに有効な厚みにすると、局部凹みが大きくなる
のに加えて、人に揺動感を与え、居住性を害する面があ
った。However, with these foamed sheets alone, when the thickness is effective to prevent impact noise, there is a problem that the local dent becomes large, and in addition, it gives a feeling of rocking to a person and impairs comfortability.
そこで、本考案者は鋭意研究を重ねた結果、ゴムを結合
剤としたパーム材よりなる弾力層１の上に支持体層２、
表面硬度（ショアーＤ）20〜50、厚さ0.5〜３mmの物体

層）３および繊維質シート層５を順次積層した下地材を
使用することにより、従来の課題を一挙に解決すること
に成功したものである。Therefore, as a result of earnest studies by the present inventor, as a result of the research, the support layer 2, on the elastic layer 1 made of palm material with rubber as a binder,
Uses a base material in which a layer (pronunciation layer) 3 and a fibrous sheet layer 5 are sequentially laminated to prevent the generation of impulsive sound when an object having a surface hardness (Shore D) of 20 to 50 and a thickness of 0.5 to 3 mm collides. By doing so, it has succeeded in solving the conventional problems all at once.
弾力層は、パーム材を通常ゴムラテックスを用いて成形

して弾性を補強したものが好ましい結果を与える。For the elastic layer, a palm material is usually formed by using rubber latex, and is finished to have a thickness of about 4 to 12 mm and a weight of about 600 to 1500 g / m 2 . In particular, a palm-lock commercially available as a cushioning material obtained by crimping coconut fiber and spraying an elastic adhesive to solidify it and impregnating it with rubber latex gives a preferable result.
ゴムを結合剤としたパーム材は他の二層との結合によ

る。Surface hardness (Shore D hardness) of 20-
A foamed synthetic resin sheet having a thickness of 50, particularly 30 to 40, and a thickness of 0.5 to 3 mm, and particularly 1.0 to 2.0 is used, but these may be a single layer or a plurality of layers, a fiber layer on the back surface, or It is also possible to line a sheet of non-foaming type synthetic resin, rubber or the like. The expansion ratio of the foam is preferably 3 to 20 times, especially about 5 times. In any case, when the surface hardness (Shore D hardness) of the foam is measured, it is necessary to select one having a value of 20 to 50. If it is too small, a local dent is generated or the comfortability is deteriorated, and if it is too large, it does not serve as a sound-preventing layer. The material constituting the foam is not particularly limited, but examples thereof include crosslinked polyethylene, polyurethane, polyvinyl chloride and the like.
