Layer-formed Chinokumi Kaiho No. 50-49917), a sound insulation foam consisting of multiple layers is attached to the entire bottom surface of a wooden board, and the foaming ratio of the sound insulation foam is made different in adjacent layers. (Utility Model Application Publication No. 61-47339) has been proposed. In these soundproof flooring materials, foam is used as a cushioning material, and since the foam is compressed or deformed by impact, the collision time becomes longer during the deformation, and changes in momentum, i.e., impulse and impact force. Even if the temporal integral value is constant, it is possible to reduce the peak value of the impact force and the impact natural frequency, reduce the impact input energy to the board, and thereby reduce the sound and vibration caused by the impact.

等の問題点があった。<Problems to be Solved by the Invention> In order to provide a sufficient soundproofing effect with these conventional soundproof flooring materials, it is necessary to appropriately set the thickness ratio between the flooring material and the tlI street material. Street materials are used as 2 to 3 times thicker than flooring materials. However, when the thickness of the cushioning material is set in this way, the flooring material itself becomes deflected to a large extent, and the real portion of the flooring material may be damaged or the real portion may become uneven. In addition, because the cushioning material is too soft, walking on the floor gets worse, and when heavy objects such as pianos, refrigerators, and furniture are placed on the flooring material and a concentrated load is applied to the flooring material, the cushioning material becomes too soft. The material will be compressed and its cushioning effect will be significantly reduced.Furthermore, if such a large load is applied over a long period of time, the restoring force of the M member itself will be weak, causing the floor surface to deteriorate. There were problems such as waving and unevenness at the butt part with adjacent flooring materials.

This is a soundproof flooring material invented as a soundproof flooring material, which is made by adhesively laminating a sheet-like cushioning material having a plurality of convex portions formed on both the front and back surfaces on the back surface of a flooring substrate. Preferably, the positions of the convex portions on the front and back surfaces of the sheet-like MfR material are different from each other on the front and back surfaces.

分になされず、防音効果を低下させるからである。The hardness of the material of the cushioning material is preferably about 30 to 65 degrees. If it is less than 30 degrees, it will likely sink when installed as a floor due to the load of heavy objects such as pianos, refrigerators, and furniture, and if it is more than 65 degrees, it will be susceptible to impact forces. This is because energy absorption is not sufficient and the soundproofing effect is reduced.

あってもよい。The convex portions formed on both the front and back surfaces of the cushioning material are generally integrally molded with a circular cross section, but the shape is not limited to, for example, a polygonal prism shape such as a square or trapezoid, a truncated cone, or a pyramid. The shape may be a hollow cylinder or a rectangular cylinder.

収すること、の２つの要素を考える必要がある。As described above, by forming a plurality of convex portions on both the front and back surfaces of the T- and FI materials, an excellent soundproofing effect can be obtained, and the reason is considered to be as follows. Furthermore, the mechanism by which solid sound acting on flooring materials is sensed by people downstairs is that solid vibrations are transmitted from the source to the flooring materials.
Propagates as vibration through the flooring material, is finally radiated into the air as sound, or is transmitted directly to the human body as vibration,
It is sensed by human hearing, and in order to prevent solid sound in this propagation system, there are two steps: buffering, that is, absorbing impact energy, and damping, that is, absorbing vibration energy. elements need to be considered.

９エネルギーを低下させることができる。かくして本発
明の構成によれば顕著な緩衝効果が得られる。First, the impact energy applied to the floor surface or the floor material substrate is propagated from the convex part on the front side of the sheet-like L shock material bonded to the back side to the convex part on the back side. However, since the contact area with the substrate is small and the amount of expansion/contraction deformation per unit area is large, the sheet-like Mf
The M, fft effect is improved compared to the case where the jR material is bonded to the entire surface of the substrate without providing a convex portion. Further, since the protrusions are provided, when impact energy is applied, deflection occurs between the protrusions, so the amount of deformation becomes larger, and the viscoelasticity of the sheet-like JUFi material itself is effectively exhibited. Furthermore, since the amount of deformation of the sheet-like cushioning material increases in this way, the 80 hours become longer, and as a result, [
9 energy can be lowered. Thus, according to the configuration of the present invention, a remarkable buffering effect can be obtained.

ができる。Next, damping is achieved by converting the applied vibrational energy into intermolecular frictional energy while propagating through the material, in other words, into thermal energy and attenuating it. Since the convex portions are formed on both the front and back surfaces of the painting material, the transmission distance of vibrational energy is correspondingly longer, and the conversion into thermal energy can be performed more efficiently.

、制振効果をもより向上させることができる。In particular, when the convex portions on the front side and the convex portions on the back side of the sheet-like <Kf'E material are formed at different positions, the deflection between the convex portions formed at different positions on the front and back surfaces becomes larger. In addition to absorbing impact energy more effectively, since the vibration energy is propagated through a zigzag path and the propagation distance is longer, the damping effect can be further improved.

To work as a
The soundproofing effect is further improved.

とができる。In addition, when the convex part of the sheet-like cushioning material is formed into a hollow cylindrical shape or a rectangular cylinder shape, the hollow part of the convex part is closed by the substrate to form a sealed space, which acts as a sound absorption chamber and at the same time plays the role of an air cushion. It also serves to further enhance the soundproofing effect.

性を向上させることができる。Note that a known damping sheet (also called a sound insulation sheet) and/or an elastic sheet may be further attached to the back side of the sheet-like cushioning material, and the material may be adhered to the flooring through these sheet materials. Damping sheets generally have synthetic rubber and synthetic resin as their main components, such as ethylene propylene rubber (EPDM), with a rubber hardness of about 60 to 80 degrees, and materials such as iron powder or iron oxide powder. Heavy substances are mixed 1
Some have a mass of ~1.2 or more and have improved sound insulation. Such a damping sheet absorbs vibration energy to enhance sound insulation and provides tensile strength to resist bending of the entire composite flooring. In addition, the elastic sheet is, for example, a polyolefin foam with a foaming ratio of 3 to 30 times, and as a second [FI material] absorbs vibration energy, prevents and absorbs unevenness, and provides an appropriate walking feeling through its elasticity. It produces effects such as increasing 4. Further, by interposing these sheets 1 to 1 between the sheet cushioning material and a floor base such as concrete, adhesiveness can be improved.

In the illustrated embodiment, the formation positions of the convex portions 4 do not match on the front and back surfaces of the cushioning material 3, but are displaced, that is, the convex portions 4a on the front side and the convex portions 4b on the back side of the cushioning material 3.

Since the MFR material 3 is joined to the substrate 1 and the subfloor 5 via the convex portions 4a' and 4b on the front and back surfaces, a space 6 serving as a sound absorption chamber is formed between them.
