本発明は、特に床衝撃音を低減させることのできる防音
床に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention particularly relates to a soundproof floor that can reduce floor impact noise.
〔従来の技術］

ト貼りではあまり問題とならなかった床衝撃音が、木質
床では大きなりレームとなって顕在化しつつある。[Prior Art] Conventionally, the floors of apartment complexes and the like were often covered with carpets, and floor impact noise from the upper floors was not transmitted to the lower floors due to the softness of the carpet. However, in recent years, carpeting has been replaced by wooden floors due to hygiene and maintenance concerns such as the occurrence of dust mites. As a result, floor impact noise, which was not much of a problem with carpeted floors, is becoming more noticeable with wooden floors.
そこで、最近防音木質床が開発されてきており、その下
地材として、ゴムや樹脂などの発泡体シートや樹脂など

性能が劣下するという問題点がある。Therefore, soundproof wooden floors have recently been developed, and foam sheets made of rubber or resin or fibrous sheets made of resin are used as the base material, but the former is thicker due to its soundproofing performance. is required, and the sinking width against the floor load increases, causing problems with the walking feel and load resistance.Also, while the latter is thin and provides soundproofing performance, when applied to slabs etc. with adhesive, Since the adhesive is impregnated and fixed into the fibers and the diameter becomes thinner, there is a problem that the soundproofing performance deteriorates when applied.
本発明は、上記欠点を鑑みてなされたもので、その目的
とするところは、歩行感や耐荷重性を満足させながら、
床衝撃音を低減させ、かつ、施工後の防音性能の劣下を
防ぐことにある。The present invention was made in view of the above-mentioned drawbacks, and its purpose is to satisfy the walking feeling and load capacity, while
The objective is to reduce floor impact noise and prevent deterioration of soundproofing performance after construction.
本発明の要旨とするところは、表面板の下部に、下地材

を用いる。The gist of the present invention is that a fibrous sheet made of synthetic resin or the like and an elastic sheet made of synthetic resin, rubber, etc. are sequentially laminated as a base material under the surface plate. Here, as the fibrous sheet, a nonwoven fabric or felt made of synthetic resin such as polyester or polypropylene, or a natural fiber sheet is used. As the elastic sheet, synthetic resin, rubber, or a foam sheet thereof is used.
床衝撃音は、軽衝撃の場合、加えられる衝撃力に比例し
、床の衝撃力緩和能力が大きいものほど、床衝撃音の低
減能力が大きい。衝撃力Ｆは、床の構成材の単位面積当
りのバネ定数Ｋ及び反発係数μによって、次式で表わさ
れる。In the case of a light impact, floor impact sound is proportional to the applied impact force, and the greater the floor's impact force mitigation ability, the greater the floor impact noise reduction ability. The impact force F is expressed by the following equation using a spring constant K and a restitution coefficient μ per unit area of the floor constituent material.
Ｆ＝Ｃ（ｌ＋μ）Ｋ３ （１）ただ
し、Ｃは衝撃源による定数である。バネ定数の小さい材
料を用いれば、同じ衝撃源に対して、衝撃力が小さ（な
り、床衝撃音が低減されるのである。F=C(l+μ)K3 (1) However, C is a constant depending on the impact source. If a material with a small spring constant is used, the impact force will be small for the same impact source, and floor impact noise will be reduced.
そこで、本発明では、下地材の一部に低弾性の繊維状シ
ートを用いている。Therefore, in the present invention, a low elastic fibrous sheet is used as a part of the base material.
さらに、繊維状シートは、スラブへの接着剤による施工

劣下があるため、繊維状シートの下部に接着剤が含浸し
ないように弾性シートを設けた。なお、床衝撃音の低減
能力を付与するため、比較的低弾性である弾性シートを
用いているのである。Furthermore, when fibrous sheets are installed on slabs with adhesive, the ability to reduce floor impact noise due to the impregnation and fixation of the adhesive deteriorates. A seat was provided. In addition, in order to provide the ability to reduce floor impact noise, an elastic sheet with relatively low elasticity is used.

As the base material 2, a fibrous sheet 3 of several thickness made of synthetic fibers or natural fibers is laminated under the fibrous sheet 3 of several thickness, and an elastic sheet 4 of several thickness thick made of synthetic resin, rubber, or their foams is laminated underneath. This is what I did.

床衝撃音の低減能力を付与することができる。In this embodiment, the low elasticity of the fibrous sheet 3 is used to alleviate the impact force and reduce floor impact noise, and the elastic sheet 4 at the bottom of the fibrous sheet 3 is used to reduce the fibrous sheet 3 during construction. This prevents the adhesive from being impregnated and fixed, and furthermore, due to the relatively low elasticity of the elastic sheet 4, it is possible to provide the ability to reduce impact force and floor impact noise.

例に比べて床衝撃音の低減効果が明らかに認められる。In this example, the surface plate 1 is made of 2.5 mm thick lauan plywood, 8 times foamed 1.7 mm thick urethane sheet, and 7 m thick lauan plywood.
The fibrous sheet 3 is a polypropylene fiber sheet with a thickness of 3 m and an areal density of 100 g/rrf, and the elastic sheet 4 is made by foaming 3 times as much as 211I11.
JISA 1418 when made into a 1-thick natural rubber sheet
Figure 2(a) shows the floor impact sound level based on . Also,
As a conventional example for comparison, FIG. 2(b) shows a case in which the base material 2 of this embodiment is composed only of the fibrous sheet 3 of the same thickness (hereinafter referred to as conventional example 1), and If the sound insulation grade specified in JIS A 1419 shown in FIG. 2(C) is applied to the one constructed only of the elastic sheet 4 (conventional example 2) of the same thickness, this example is L-45, conventional example 1. is L47, and Conventional Example 2 is L-48, and the effect of reducing floor impact noise in this example is clearly recognized compared to the conventional example.

止効果がわかる。Furthermore, in this example and Conventional Example 1, the amount of deterioration in the ability to reduce floor impact noise after adhesive construction on the slab was determined according to JIS A
1419, expressed as the amount of deterioration in the sound insulation class.
Shown in the table. In this example, the amount of deterioration after construction was smaller than in Conventional Example 1, which shows the effect of preventing the adhesive from impregnating and fixing into the fibrous sheet 3 in Table 1.

The material and composition of the surface board, the desired soundproofing performance, and the type and type of fiber.
Although it varies depending on areal density, fiber diameter, etc., it is generally desirable that the Young's modulus is 105 N/po or less in order to have a soundproofing performance of 155 or less, which is called a soundproof floor. Further, the Young's modulus of the elastic sheet 4 is also the same, but if the soundproofing performance is to be ensured only by the fibrous sheet 3, the Young's modulus of the elastic sheet 4 is not limited to the above.

。As described above, the soundproof floor of the present invention has a fibrous sheet made of synthetic fiber or the like and an elastic sheet made of synthetic resin, rubber, etc. laminated as base materials in the lower part of the surface board. The low elasticity reduces impact force and reduces floor impact noise, and the elastic sheet at the bottom of the fibrous sheet prevents deterioration in soundproofing performance due to adhesive impregnation and fixation in the fibrous sheet during construction. It can be prevented.
