Description

Inter-floor noise prevention material and multi-story building construction structure using the same {INTER-FLOOR NOISE PREVENTION MATERIAL AND ITS CONSTRUCTION STRUCTURE}

The present invention relates to an interfloor noise prevention material and a construction method thereof, and more particularly, to an interfloor noise prevention capable of preventing vibration or impact sound from being transmitted to the side of the lower floor through the floor and walls of the upper floor in a multi-story building. It is about materials and their construction methods.

In general, in the case of interlayer noise prevention materials, it is desirable to satisfy the following six conditions.

The first condition is that the noise transmission rate of less than 58db for light impact sound and 50db for heavy impact sound must be provided as the minimum performance, and the first grade of less than 43db for light impact sound and 40db for weight impact sound performance should be close to .

The second condition is that the installation and construction height must be low. As the height of the floor increases, the height of the indoor space decreases. Therefore, in the case of inter-floor noise prevention materials, it is preferable to manufacture them with a thickness of 5 mm to 50 mm or less, but under the condition that performance is maintained, it is possible to It is preferable that the thickness is made thin.

The third condition is that since 40 mm of aerated concrete and 40 mm of finishing mortar are added above the floor base, the load of the aerated concrete and finishing mortar is applied to the inter-floor noise prevention material, so that the thickness does not change over time in the case of the inter-floor noise prevention material. It must be durable enough to withstand the load.

The fourth condition is that the installation and construction are not difficult and complex, and the transportation installation and construction must be easy and simple.

The fifth condition is that the material of the interlayer noise prevention material should not be made of a material that is harmful to the human body or has a bad effect on the environment.

The sixth condition is that it should have a durability equivalent to 30 years or more, which is the durability period of reconstruction of an apartment building.

As a method for preventing noise between floors that must have such conditions, a method for preventing noise using a solid vibration transmission mechanism is generally used, and a method for preventing noise using the solid vibration transmission mechanism uses a synthetic resin as a main material. There is a mat-type noise blocking material manufactured to have high elasticity by foaming or processing and thus reducing the transmission rate of noise.

In the case of such a conventional general mat-type anti-noise material, there are advantages in that the price is low, the height of the installation space is low, and the construction is simple.

However, in the case of the above mat-type anti-noise material, if the mechanical strength is made hard by increasing the mass to support the load of the finishing cement layer including the hot water pipe stacked on the top of the noise material, the noise transmission rate is increased, and the noise transmission rate is reduced. There is a correlation between the mechanical strength of the material and the noise transmission rate, such as when the material is softened to lower the load, such as being distorted because it cannot withstand the load.

Referring to the following drawings, preferred embodiments of the present invention will be described in more detail.

1 is a cross-sectional view for explaining an interlayer noise prevention material according to a first embodiment of the present invention.

Referring to FIG. 1, in the interlayer noise prevention material 100 according to the first embodiment of the present invention, a plurality of gas pockets 120 filled with gas are formed at predetermined intervals between a pair of synthetic resin sheets 110. It may be manufactured by attaching a pair of synthetic resin sheets 110 by stacking them up and down.

For example, the gas pocket 120 may be filled with at least one of air, hydrogen, helium, argon, oxygen, carbon dioxide, and nitrogen.

2 is a diagram for explaining an energy conversion rate when shock vibration energy is transferred between a solid wall and a gas space.

As shown in FIG. 2 , energy is transferred to the gas within the section of the adjacent space B 220 by the vibration of the cement wall A 210 and gas vibration or sound is generated. At this time, the vibration energy transmitted to the gas, which is the medium, depends on the material density of the gas. Since the gas has a low material density, the amount of energy transmitted from the wall to the gas is very small even though the sound is loud to the human ear.

When the gas vibration or sound energy is transmitted back to the cement wall C (230) as solid vibration, a large amount of sound is diffusely reflected, and the vibration is converted into heat, resulting in heat loss. As the density and mass of the cement wall C (230) increase, The solid vibration transmitted from the gas vibration is further reduced, resulting in a drastically lowered vibration conversion factor.

On the other hand, the KS standard density of cement is 3.10 to 3.15 g/cm 3 , and the density of air is 0.00122 g/cm 3 at 1 atmospheric pressure of 15° C. That is, when there is a cement wall and an air wall of the same volume, the difference in the amount of vibration energy passing through is approximately 1/2500, and accordingly, when the vibration energy passes through the cement wall and the air wall in series, It can be seen that the decrease

Therefore, when the cement wall and the air wall pass through the wall connected in series twice as shown in FIG. 220) is reduced to 1/2500 to 0.0004, and when transmitted to the cement wall C (230), the vibration energy is transferred to the gas in space D (240) and reduced to 1/2500 again to a very small amount of vibration energy of 0.00000016. When hydrogen (density: 0.00009 g/cm 3 ) or helium (density: 0.00019 g/cm 3 ), which is lower in density than air, is filled in space B (220) and space D (240), the effect is even greater. It can be improved, and it can be seen that when vibration energy passes through materials with different densities, the energy decreases according to the density of the material, which can be an effective interlayer prevention material.

Accordingly, a pair of synthetic resin sheets 110 are stacked up and down so that a plurality of gas pockets 120 filled with gas are formed at predetermined intervals between the pair of synthetic resin sheets 110. The interlayer noise prevention material 100 according to an embodiment of the present invention in which the pocket 120 is filled with any one gas selected from air, hydrogen, and helium is air, hydrogen, helium, etc. When the gas is filled in the gas pocket 120 and the vibration hits the cement wall or the floor, some of it is reflected or disappears, and only the remaining reduced energy is transmitted as sound, thereby effectively blocking noise between floors in a multi-story building.

The pair of synthetic resin sheets 110 are bonded together so that they can be continuously formed.

On the other hand, as shown in (b) of FIG. 3, when the gas pocket 120 is manufactured to protrude in both the vertical direction of the interlayer noise prevention material 100, a plurality of pluralities are formed on the outer circumferential surface of the first circular roller mold 310. Two pocket forming grooves 311 may be formed at predetermined intervals.

As shown in FIG. 4, the gas pocket 120 of the interlayer noise prevention material 100 according to the present embodiment is formed by stacking a pair of synthetic resin sheets 110 vertically and then forming a plurality of holes provided in a flat mold 330. It may also be formed by bonding a portion pressed by the pocket forming adhesive 331 by applying pressure using the pocket forming adhesive 331 .

5 is an exemplary diagram illustrating a process of manufacturing a synthetic resin sheet.

For example, the synthetic resin sheet 110 is laminated so that the metal thin film 112 is interposed between the pair of synthetic resin films 111, as shown in (a) of FIG. 5, and then a pair of high-temperature compression rollers ( 340) can be manufactured by adhering by passing between them.

Here, as the metal thin film 112, any one of an aluminum thin film and a copper thin film may be selected and used.

Referring to FIG. 8, in order to construct floors and walls of a multi-story building using the inter-floor noise prevention material according to an embodiment of the present invention, the inter-floor noise prevention material 100 is applied to the base cement floor 410 of the multi-story building.

9 is a view showing another example of constructing a floor and a wall of a multi-story building using an inter-floor noise prevention material according to an embodiment of the present invention.

Referring to FIG. 9, in order to construct the floor and walls of a multi-story building using the inter-floor noise prevention material according to one embodiment of the present invention, the floor leveling correction bubble cement layer is placed on the upper surface of the base cement floor 410 of the multi-story building. 440 and the finishing cement layer 420 are sequentially stacked, and a plurality of gas pockets 120 are filled with gas between a pair of synthetic resin sheets 110 on top of the finishing cement layer 420 at predetermined intervals. After stacking the interlayer noise prevention material 100 formed by stacking and attaching a pair of synthetic resin sheets 110 up and down to form, and then attaching the floor finishing material 450 on top of the interlayer noise prevention material 100, The floor finishing material 450 can be supported in the form of a support body by the plurality of gas pockets 120 filled with gas.

Here, the inter-floor noise prevention material 100 may be attached to the wall 460 of the multi-story building in such a way that two layers are stacked.

Meanwhile, a noise prevention vibration block layer 430 may be further attached to the inter-floor noise prevention material 100 attached to the wall 460 of the multi-story building.

Again, with reference to FIGS. 1 to 9, the effect of the inter-floor noise prevention material according to an embodiment of the present invention and the construction structure of a multi-story building using the same will be described.

1 to 9, according to the inter-floor noise prevention material according to an embodiment of the present invention and the construction structure of a multi-story building using the same, the inter-floor noise prevention material 100 is a pair of metal thin films 112 formed It is formed by stacking and attaching a pair of synthetic resin sheets 110 up and down so that a plurality of gas pockets 120 filled with gas are formed at predetermined intervals between the synthetic resin sheets 110.

Therefore, the gas pocket 120 filled with the gas is sealed with the synthetic resin film 111 and the metal thin film 112 so that the gas inside the gas pocket 120 does not leak out without increasing the mass of the synthetic resin sheet 110. As a result, even if a continuous load is applied to the gas pocket 120 by the high load finishing cement 420 or the floor finishing material 450, the gas pocket 120 finishes the cement 420 without changing the thickness of the gas pocket 120. ) or the floor finishing material 450 can be firmly supported in the form of a support body.

That is, when the floor height of a multi-story building increases, the height of the indoor space decreases, so the inter-floor noise prevention material 100 must be manufactured so that the height of the installation space is within 5 mm to 50 mm. good night.

However, in the case of a conventional general noise floor covering in which the gas pocket supports a high-load finishing cement or floor finishing material in the form of a support, a plurality of gas pockets filled with gas inside are simply laminated with a pair of synthetic resin films. It is manufactured by attaching it so that it is formed at predetermined intervals.

Therefore, when a thin synthetic resin film is used to keep the construction height low, the noise transmission rate is reduced because the noise barrier between floors is soft, but the gas pocket is not able to withstand the high load of the finishing cement or floor finishing material and is crushed, or the inside of the gas pocket is damaged. Gas leaks out of the synthetic resin film, and the gas pocket is crushed and adhered to, thereby losing the function of the gas pocket that can significantly reduce the transmission rate of noise.

On the other hand, in order to solve this problem, if the mechanical strength is hardened by increasing the mass of the synthetic resin film, the noise transmission rate is increased and the function as an interlayer noise prevention material is lost.

On the other hand, in the interlayer noise prevention material 100 according to an embodiment of the present invention, the gas pocket 120 filled with the gas is sealed with the synthetic resin film 111 and the metal thin film 112, so that the synthetic resin sheet 110 Even without an increase in mass, the gas inside the gas pocket 120 does not leak to the outside, so even if a continuous load is applied to the gas pocket 120 by the high load finishing cement 420 or floor finishing material 450, the gas pocket The gas pocket 120 can firmly support the finishing cement 420 or the floor finishing material 450 in the form of a support body without changing the thickness of the 120.

As such, the inter-floor noise prevention material and the method for constructing a multi-story building using the same according to an embodiment of the present invention use a synthetic resin sheet 110 in which a metal thin film 112 is formed on a synthetic resin film 111, and a plurality of gas pockets 120 ) is formed at predetermined intervals, so that the gas inside the gas pocket 120 does not leak out to the outside even without an increase in the mass of the synthetic resin sheet 110, and the gas pocket 120 does not change its shape for a long time, and the finishing cement 420 with a high load The floor finishing material 450 may be firmly supported in the form of a support body.

Therefore, the inter-floor noise prevention material and the method of constructing a multi-story building using the same according to an embodiment of the present invention can minimize the height of the installation space while keeping the sound transmission characteristics low, and can be applied to high-load finishing cement without shape deformation for a long time. (420) or the floor finishing material (450) can be firmly supported, so that the interior space of the multi-story building is not reduced due to the construction of the inter-floor noise prevention material (100), and the inter-floor noise generation rate of the multi-story building can be significantly reduced In addition, it is possible to significantly increase the service life of the interlayer noise prevention material 100.
