実用的な硬さにすると、肝心の軽量床衝撃音遮音
性能が不足してしまうという欠点があつた。(Prior Art) For the floors of apartment complexes such as buildings, the direct pasting method of directly pasting flooring materials onto concrete surfaces has become widespread. Due to the demands of the times, carpet and vinyl chloride floors are being replaced by wood floors, but even with wood floors, foamed plastic foam is attached to the back side and a direct attachment method is used. Foamed plastic foam, rubber, urethane rubber, etc. do not have the effect of damping impact energy due to friction between fibers, and can only absorb impact energy by using trapped air as an air spring. There are methods such as processing, and there are some improvement effects, but in order to achieve the same level of improvement as fiber pine, the number of air springs must be increased, and as a result, it becomes impractical as a flooring material. In many cases, foamed plastic foam becomes soft, and if the expansion ratio is increased to make it soft, it relies on the air spring created by the trapped air, so if a load is applied over a long period of time, the air will evaporate. Air tends to leak through the enclosing plastic membrane, reducing its cushioning effect, and ultimately, if it were made to be hard enough for practical use, it would lack the critical sound insulation performance of a lightweight floor impact sound.

出来るものがなかつた。 A dry floating floor construction method has also been devised that uses high-density glass wool on the underside of the wooden flooring, but in this case,
Although lightweight impact noise has been improved, weight impact noise has not been improved, and sagging due to local loads can make the floor surface uneven.Therefore, none of them has been practically satisfactory.

ある。(Problem that the invention aims to solve) Generally, in order to improve lightweight impact noise, it is best to use a cushioning material in the middle or on the back side of the base material. There is a need to. In this case, as mentioned above, sagging and unevenness become a problem. On the other hand, the most effective way to improve weight impact noise is to make the concrete slab thicker, and it is preferable to increase the rigidity and density of the flooring material on the slab, but this is disadvantageous to improving lightweight impact noise, so both impact It is extremely difficult to improve the sound at the same time.

ある。 Therefore, with direct-laminated flooring, the light impact noise is usually improved, and the weight barrier sound is prevented by increasing the thickness of the slab to the extent that it does not deteriorate more than the bare slab characteristics, but this invention not only improves the light impact noise, but also The present invention provides a sound insulating flooring material that also slightly improves weight impact noise.

(Means for Solving the Problems) An embodiment of this invention will be described below with reference to the drawings. On the front surface of a vibration-proof sheet 4 made of a viscoelastic substance, a plywood 2 with a thickness of 6 mm or less and a decorative veneer 1 is placed on the back side. A plywood 3 with a thickness of 6 mm or less is pasted on each of the plywood 3 on the back side, and a first gap 7 in a linear shape, for example, reaching the vibration-proof sheet 4 is carved on the back side of the plywood 3, and a foamed plastic foam or rubber is further attached on the back side. A carpet 5 having a buffer layer 6 such as the above is attached to the plywood 3 with a second cavity 8 having a shape different from the first cavity 7, for example a circular shape.
この構成の衝撃音低減の要素は一つ一つの要素

制振材に吸収されるため、充分に発揮でき、総合
的に大きな効果を発揮しているものである。 The impact sound reduction element of this structure is not just a collection of individual elements, but a combination of individual elements that are related to each other.In other words, the carpet is glued to the back side, and the plywood part has a viscoelastic sheet inside. By adopting the sandwich sandwich structure, the damping effect of the viscoelastic sheet is supported by the appropriate cushioning properties of the carpet, and the vibration energy is absorbed by the damping material, so that it can be fully exerted, and the overall It has been shown to have a significant effect.
先ず粘弾性物質からなる防振シート４について

防振シートが衝撃音減衰に効果が大きい。 First, regarding the vibration-proof sheet 4 made of a viscoelastic substance, there are various sheets that can be made from various combinations of rubber, rigid resin, etc., but vibration-proof sheets that are made of asphalt and urethane resin and inorganic substances are particularly suitable. Great effect on impact sound attenuation.
この防振シートの両面に６mm厚以下の合板〔表

好ましくは表面側合板については４mm以下がよ
い。 Plywood with a thickness of 6 mm or less (with a decorative veneer on the front side) is pasted on both sides of this anti-vibration sheet to form the basic base material A. At this time, the thinner the plywood, the better. If it is too thick, it will lose its function as a floorboard, such as causing dents against heavy objects, and if it is too thick, the rigidity will increase and light impact noise will worsen, so preferably the surface plywood should be 4 mm or less.

染むようにするために用いる。 Furthermore, the reason why the first void portion 7 is carved on the back surface of the basic base material A is that the moment an impact force acts on the flooring material, the impact force is absorbed as deformation energy of the base material, and then the cushioning material absorbs the impact force as deformation energy. It is absorbed by the buffering effect, that is, it is absorbed by two buffering effects, so it improves the sound insulation effect, eliminates the rigidity of the wooden flooring, and gives it flexibility to adapt to the unevenness of the concrete slab surface. be. At the same time, a buffer layer 6 made of foamed plastic foam or rubber is also used to improve the sound insulation effect and to adapt to the unevenness of the concrete slab surface.

る。 Here, providing a gap between the carpet having a buffer layer and the plywood 3, and further making the shape of the gap different for each, has a very large effect on the sound insulation effect. Basically, the shape of the void may be any shape, but circular, non-circular, and linear shapes are preferred from the standpoint of workability, strength maintenance, etc., and curved shapes are difficult to carve. The shape of this gap can be provided in accordance with the frequency for which attenuation is desired. That is, a shape with a damping effect can be found by adjusting the shape and the gap. For example, if it is circular and has a porosity of 15%, it will have a large damping effect at 250Hz. Furthermore, in the first gap, 250Hz,
By finding a shape that has a damping effect at 125 Hz in the second cavity, it is possible to find attenuation for both frequencies at once. Although there is no particular data on the method of adjusting the shape of the void and the frequency at which the attenuation of the porosity is to be determined, it is possible to conduct experiments by conducting tests on a large number of specimens with various shapes and porosity. , the shape of the void and the porosity are determined empirically. Also, because the shapes of the two voids are different, the material has appropriate rigidity while maintaining flexibility, so it does not cause extreme stiffness when loaded with heavy objects. The reason for this is that the gap has a cross-sectional defect, so its strength is lower than that of the other parts. Therefore, if the shapes and installation positions of the two gaps were the same, The cross-sectional loss of this part is extremely large, and this part is extremely prone to breakage when local loads are applied.Even if the sound insulation performance is good, it is easy to break.
It becomes less practical. However, if the shapes and positions of the two voids are different, the above-mentioned cross-sectional defect will be only a partial one, and breakage will be less likely to occur.

果が発揮されるのである。 On the other hand, carpet is usually effective in reducing lightweight impact noise when used as a surface material.
If it is used on the back side of a rigid wooden flooring material, it will be almost ineffective, but in the case of this invention, it is extremely effective by using the carpet and the voids carved on the back side of the wooden flooring material. A method was established. This means that absorption of impact energy places a burden on the carpet, which is a cushioning material, and no matter how effective the cushioning effect of the carpet is, it cannot fully absorb the impact energy. However, although it is not as good as carpet, if you use viscoelastic damping sheets, saw grooves, voids, and other softening treatments, it will become relatively softer than if it were not done. Impact energy is absorbed not only by the carpet, which acts as a cushioning material, but also by the softened base material of the wooden flooring, providing a sound insulation effect.

ーがかなり消費されてしまうからである。 Among carpets, this effect is particularly large for needle punch carpets. After various studies, synthetic resin fibers such as polyester, polypropylene, acrylic, and nylon are usually used as threads, but the size of these threads is too thick. If it is too thin, or if the amount used per unit area (basis weight) is too large or too small, the improvement in lightweight impact sound will be weak. The one with the best one was the best. Within this range, the effect of improving lightweight impact noise is significant, and heavy impact noise does not particularly deteriorate. Furthermore, since the rigidity of the plywood substrate is considerably lost due to the carving of the voids in the plywood 3, the otherwise ineffective carpet is now once again serving as a damping effect. Regarding the influence of carpet yarn thickness (denier) and area weight (g/m 2 ) on the sound insulation effect, if the thickness and area weight are outside this range, it may be too hard and the cushioning effect may be insufficient. ,
Or, if it is too soft, the so-called double-strike phenomenon occurs, in which the base material bottoms out on the carpet base before absorbing the impact, especially in the case of heavy impact sound.
On the contrary, the sound insulation performance tended to deteriorate, so this is the empirical value obtained through the test.Also, the reason why the carpet helps in damping effect by carving voids is that the plywood base This is because the rigidity of the material is lost, and a considerable amount of impact energy is consumed in deforming the base material.

It may be formed into a seal shape while foaming in a heating furnace. It would be better if they were strongly integrated.

According to this invention, the impact sound applied to the surface of the wooden floor material is greatly attenuated by the vibration isolating sheet 4 made of a viscoelastic material, and then the first cavity provided on the back surface of the basic base material A is used. In other words, at the moment when the impact force acts on the floor material, the impact force is absorbed as deformation energy of the base material, and the back surface of the vibration isolating sheet 4 is
The vibrations are dispersed through the plywood 3 existing between the saw grooves of the plywood, and are then finely dispersed into the short fibers of the carpet 5, and at the same time are also dispersed through the second voids, and finally absorbed into the foamed plastic foam. The vibration damping effect is extremely large, and sound insulating flooring absorbs impact energy in a complex manner through its multilayered structure, including saw grooves and viscoelastic damping materials. Therefore, if the performance is the same as that of the conventional method, it is possible to make the cushioning material that much harder. Since a sufficient sound insulation effect can be obtained even if the material is not soft, there is little deformation after construction, the floor surface does not become uneven, and it has extremely beneficial effects such as being able to be used without any problem.
