Description

Floor noise prevention material of apartment}

The present invention relates to an interfloor noise prevention material of an apartment house, and more particularly, an interfloor noise prevention material of an apartment house installed on the slab to block the transmission of the impact sound generated on the upper floor of the ondol heated apartment house to the lower floor. It is about.

Interfloor noise (層間騷音) is noise pollution that occurs mainly in multi-family houses or apartment houses such as apartments.

Floor noise is collectively called the sound of toilet water, floor impact sound, piano sound, audio sound, dialogue sound, TV sound, etc., among floor noises, floor impact sound is lightweight impact sound (floor impact sound due to relatively light and hard impact, legal standard 58㏈) Below) and weight impact sound (floor impact sound caused by heavy and soft impact, legal standard less than 50㏈).

In the past, a problem began to emerge as apartments and other apartments became more common in the past, and due to the characteristics of apartments where many households live with a single layer of walls and floors between floors, the noise between floors is causing the problem. Conflicts can arise.

In particular, among the inter-floor noise, the floor impact sound (solid transmission sound) generated by the direct impact on the concrete surface is easily transmitted to neighboring households, and this noise is mainly caused by the sound of children running upstairs and downstairs and attracting objects. It is the sound of falling or falling, and the interfloor noise, like other noise pollution, adversely affects mental and physical health, and it has been a long time since it has emerged as a social problem such as many problems and complaints between neighbors.

In order to solve such an interfloor noise problem, the Ministry of Land, Infrastructure and Transport Notification No. 2016-824, Apartment House Floor Impact Sound Blocking Structure Recognition and Management Standard, Presidential Decree No. 28628, Housing Construction Standard, etc., the interfloor floor impact sound blocking structure standard for noise prevention, etc. It presents housing construction standards related to the prevention of inter-floor noise.

In addition, various research papers to prevent inter-floor noise (experimental study on the effect of reducing floor impact sound according to changes in slab thickness and stiffness-Taehee Kim, performance evaluation by alternative floor finish structures considering floor impact sound in apartment houses, etc.) have been published and published. have.

Therefore, in order to prevent interlayer noise, which is a social problem even in the past, as published in Patent No. 10-1740046, it is placed on the floor of the interlayer slab and is a gel material, so as to block the floor impact sound that belongs to vibration. One gel sheet; A rubber sheet laminated on the top of the gel sheet and made of a rubber material to block a weight impact sound belonging to a low frequency; A foam sheet laminated on top of the rubber sheet and having a foam material to block a lightweight impact sound belonging to a high frequency; And an adhesive sheet laminated between the foam sheet, rubber sheet, and gel sheet, respectively.

However, since the interfloor noise prevention material of the conventional multi-family housing is a structure in which several panels are stacked to prevent noise, when an instantaneous load (a bang-type instantaneous load, which is a measurement method of weight impact sound) is applied about 4,500N/m2, the impact As energy and vibration energy are converted into heat energy by the interfloor noise prevention material of an apartment house, there was a problem in that the shock energy and vibration energy generated by the instantaneous load applied to the floor before the noise is absorbed are transferred to the lower floor as it is. .

Republic of Korea Utility Model Registration No. 20-0322187 (Registration Date: August 06, 2003) Republic of Korea Patent Publication No. 10-2015-0031580 (Publication date: March 25, 2015)

An object of the present invention was conceived to solve the conventional problems as described above, and the main raw material is a rubber having excellent elastic resilience and vibration damping properties to attenuate the interfloor noise of apartments or buildings. The instantaneous load (the bang type instantaneous load, which is a method for measuring the weight impact sound) is about 4,300kg/m2 on the upper floor plate by the interlayer noise prevention material equipped with an air pocket having a thickness of ∼2.5mm and a height of 10mm∼30mm. Even when applied, the impact energy and vibration energy are converted and absorbed into heat energy by the air pocket formed between the slab and the foamed concrete layer, and the purpose is to provide an interfloor noise prevention material for an apartment house that prevents the impact sound and vibration from being transmitted to the lower floors.

In order to achieve the above object, the interfloor noise prevention material of the apartment house of the present invention is made of rubber, which has excellent elastic resilience and vibration damping properties, as the main raw material, with a thickness (T) of 1,0mm to 2.5mm, and a height of 10mm to 30mm ( h) is achieved by forming a plurality of cylindrical air pockets 110 at regular intervals.

On the other hand, the air pocket 110 is formed in a wide upper portion and a narrow upper light narrow shape, so that the shock energy and vibration energy generated from the upper portion are efficiently introduced into the air pocket 110 and are converted into thermal energy to the outside. It turns out that it is more desirable to allow it to be discharged.

According to the present invention, the rubber itself has excellent elastic restoring force and vibration damping characteristics, and the shape of the cylindrical air pocket having a height of 10 mm to 30 mm provides excellent cushioning effect, as well as the air in each air pocket. By exerting an effect, there is an effect that the buffering effect is doubled.

On the other hand, the air cushion effect of the air filled in the air pocket is a very useful invention that has the effect of being able to semi-permanently maintain durability by doubling the restoring force when an excessive load or impact is applied.

The interfloor noise prevention material of the apartment house of the present invention is made of rubber, which has excellent elastic resilience and vibration damping properties, as the main raw material, and has a thickness (T) of 1,0mm to 2.5mm and a height (h) of 10mm to 30mm. A plurality of pockets 110 are formed at regular intervals.

On the other hand, the air pocket 110 has a wide upper portion and a narrow upper light lower narrow shape.

The effect of the construction of the interfloor noise prevention material 100 of the present inventors multi-family house constructed as described above will be described.

4 is a cross-sectional view showing an interlayer floor slab of a general apartment, etc., in which an insulating material 200 made of a foam resin such as an EPS material and a prevention material 100 is sequentially mounted on the concrete slab 500, and air bubbles thereon Concrete 300 and finishing mortar 400 are sequentially constructed.

In such a floor slab construction process, the prevention material 100 of the present invention not only exhibits a buffering ability by its own elastic force, but also air compression occurs as the heat insulating material 200 is in close contact with the upper portion of the air pocket 110 to buffer the air cushion. You will show your ability.

That is, when an instantaneous load (bang-type instantaneous load, which is a method of measuring weight impact sound) is applied to the upper floor plate of about 4,500N/m2, the shock is primarily transmitted to the insulating material 200 to absorb the shock energy and vibration energy. After being transferred to the present inventors prevention material 100, the shock energy and vibration energy transmitted from the insulation material 200 are absorbed so that secondary attenuation is achieved by the self-elastic force of the prevention material 100. The impact energy and vibration energy remaining after being absorbed by the prevention material 100 are introduced into the air pocket 110 formed between the slab 500 and the foamed concrete 300, and then the air pressure contained in the air pocket 110. The shock energy and the vibration energy are absorbed by this, and at the same time, the energy is converted into thermal energy, thereby being distributed to the outside of the air pocket 110.

At this time, the air pocket 110 is formed to have a height h of 10 mm to 30 mm because performance is degraded when the height is too low.

On the other hand, if the thickness (T) of the prevention material 100 is too thin, stability is insufficient, and if it is too thick, it is formed in a thickness (T) of 1,0mm to 2.5mm because the performance decreases and the manufacturing cost increases. As the phenomenon occurs, the insulation characteristics are exhibited.

In addition, even if an excessive load or impact is applied to the prevention material 100, the air pocket 110 is prevented from being excessively crushed due to the internal pressure of the air confined in the air pocket 110.

In addition, even when a light weight load or impact sound occurs on the upper floor plate 600, the prevention material 100 installed between the slab 10 and the foamed concrete 300 acts as a secondary buffer, while the light and heavy sound Is effectively attenuated correspondingly.

In addition, the air pocket 110 of the interfloor noise prevention material 100 of the multi-family house of the present invention is formed in a narrow upper and lower part of the upper and lower sides, so that the prevention material 100 and the prevention material 100 ) Are stacked and transported easily, and at the same time, it is easy to produce the interlayer noise prevention material 100 so that residual deformation is excellent during production.
