【産業上の利用分野】本考案は床材特に家屋の階上部分
に使用して床面の衝撃による固体音の階下への伝搬を防
止する防音床材に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof flooring material which is used for flooring materials, especially for the upper floor of a house, and which prevents solid sound from being transmitted downstairs due to impact of a floor surface.
【０００２】[0002]
【従来技術およびその問題点】従来の建材への衝撃によ
る固体音の伝搬を防止する防音建材としては、床板基板
の裏面に弾性を有するシート状物として合成樹脂性シー

の発泡体または、不織布等、種々の緩衝材を貼着したも
のが知られている。2. Description of the Related Art Conventional soundproof building materials for preventing propagation of solid sound due to impact on building materials include synthetic resin sheets, natural rubber sheets, and synthetic rubber sheets having elasticity on the back surface of a floor board. A sheet, or a sheet to which various cushioning materials such as a foam or a nonwoven fabric thereof are adhered is known.
【０００３】そしてこれらのシート状物は、合成の低い
緩衝材であり、その緩衝効果により直ちに衝撃力を受け
た場合、その緩衝材の変形される間、緩衝時間が長くな
り、運動量の変化、すなわち力積、衝撃力の時間的積分
値は一定であっても、衝撃力のピーク値や衝撃固有周波
数を低下させ、基盤への衝撃入力エネルギーは低減され
衝撃による音や振動は共に低下される。[0003] These sheet-like materials are low-synthetic cushioning materials. If the cushioning material is immediately subjected to an impact force due to the cushioning effect, the buffering time increases while the cushioning material is deformed. That is, even if the time integrals of the impulse and the impact force are constant, the peak value of the impact force and the natural frequency of the impact are reduced, the input energy to the base is reduced, and the sound and vibration due to the impact are both reduced. .
【０００４】またこれらの緩衝材を建材の裏面に複合し
た時、衝撃力は建材の曲げ振動で生じる緩衝材の伸縮変
形によって、エネルギー吸収を行なうものである。When these cushioning materials are combined on the back surface of a building material, the impact force absorbs energy by expansion and contraction of the cushioning material caused by bending vibration of the building material.
【０００５】しかしながら、防音機能は建材と緩衝材と
の厚さ比の影響が大きく、防音機能を向上させるために
は、建材に対する緩衝材の厚さ比を２−３倍にする必要
がある。このため緩衝材が厚くなりすぎてしまい、建材
全体のたわみがひどく建材の接続部の破損の発生、床材
に用いた場合には、歩行の不安感の原因となるという問
題点を残している。However, the soundproofing function is greatly affected by the thickness ratio between the building material and the cushioning material. In order to improve the soundproofing function, the thickness ratio of the buffering material to the building material needs to be 2-3 times. For this reason, the cushioning material becomes too thick, and there is a problem that the bending of the entire building material is severe and the connection portion of the building material is damaged, and when used as a floor material, it may cause anxiety of walking. .
【０００６】特にこの緩衝材の収縮に起因するたわみの
問題は、発泡体シートを用いた緩衝材において問題とな
っている。[0006] In particular, the problem of bending caused by shrinkage of the cushioning material is a problem in cushioning materials using foam sheets.
【０００７】一方、不織布を緩衝材として用いた防音床
材は、収縮の問題は少ないものの、実際に施工された状
態の防音床材の有する防音性能が、試験段階で認定され
た防音性能に比べひどく低下するという問題を持ってい
た。On the other hand, the soundproofing flooring using the nonwoven fabric as a cushioning material has a small shrinkage problem, but the soundproofing performance of the actually installed soundproofing flooring material is lower than the soundproofing performance certified at the test stage. Had the problem of severe decline.

た防音床材の防音性能が大きく影響を受けるという問題
点を有していた。[0008] This is because the adhesive used to fix the floorboard to the ground surface permeates into the non-woven fabric and hardens in the non-woven fabric at the working stage, thereby reducing the buffer effect of the non-woven fabric. The amount of adhesive applied to the ground surface during construction varies greatly depending on the site installer, and the amount of adhesive greatly affects the soundproofing performance of the installed soundproof flooring. Had a point.

For example, plywood, particle board, hard board,
L. V. L. A floor board substrate 1 made of (parallel plywood) or the like and a non-woven sheet 2 adhered to the back surface of the floor board substrate 1. The non-woven sheet 2 is made of synthetic resin fibers such as polyester, polypropylene, and nylon. A non-woven fabric is formed by forming a water-impermeable coating layer 2a on the back side surface layer.

The portion forms an impermeable coating layer.

【００１５】また、裏溝により基板の一部が分割され音
が伝播しにくくなり防音効果をさらに向上させることが
できる。Further, a part of the substrate is divided by the back groove, so that sound is not easily transmitted, and the soundproofing effect can be further improved.

As shown in FIG. 3, for example, an intermediate synthetic resin foam sheet 4 having an excellent buffer effect is laminated in the middle of the substrate 1 such that a foam synthetic resin sheet is sandwiched between plywoods, or as shown in FIG. As described above, a material laminated on the back surface of the floor board substrate via the back surface synthetic resin sheet 5 having a buffer effect can also be used.
