Description

Floor noise prevention material of apartment

The present invention relates to a noise prevention material between floors of an apartment house, and more particularly, an interfloor noise prevention material installed on a slab to block the impact sound generated on the upper floor of an ondol heating apartment house from being transmitted to the lower floor. is about

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

Inter-floor noise is a generic term for toilet water, floor impact sound, piano sound, audio sound, dialogue sound, and TV sound. Below) and heavy impact sound (floor impact sound caused by heavy and soft impact, legal standard 50dB or less).

In the past living mainly in single-family houses, the problem started to arise as multi-family houses such as apartments became common today. quarrels may arise.

In particular, among floor noise, floor impact sound (solid-transmission sound) generated by a direct impact on the concrete surface has the property of being easily transmitted to adjacent households. Like other noise pollution, inter-floor noise has a bad effect on mental and physical health, and it has long been raised as a social problem such as many problems and complaints between neighboring residents.

In order to solve the inter-floor noise problem, Ministry of Land, Infrastructure and Transport Notification No. 2016-824 Standards for Recognition and Management of Floor Impact Sound Blocking Structures for Apartment Houses, Presidential Decree No. 28628 Regulations for Housing Construction Standards, etc. It suggests housing construction standards related to noise prevention between floors.

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

Therefore, in order to prevent inter-floor noise, which has become a social problem even in the prior art, as disclosed in Patent Registration No. 10-1740046, it is placed on the floor surface of the inter-floor slab and is a gel material to block the floor impact sound belonging to the vibration. one gel sheet; a rubber sheet laminated on top of the gel sheet and made of a rubber material to block a heavy impact sound belonging to a low frequency; a foam sheet laminated on top of the rubber sheet and made of a foam material to block a light 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 such a conventional apartment house has a structure in which several panels are stacked for noise prevention, an instantaneous load such as a weight impact sound (a bang-type instantaneous load that is a weight impact sound measurement method) of 4,500N/m2 is applied. As the energy and vibration energy are converted into thermal energy by the noise prevention material between floors of the apartment building, there is a problem that the shock energy and vibration energy generated by the instantaneous load applied to the floor before the noise is absorbed is transmitted as it is to the lower floor. .

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

The object of the present invention was devised to solve the conventional problems as described above, and even when an instantaneous load (a bang-type instantaneous load that is a weight impact sound measurement method) of about 4,300 kg/m2 is applied to the bottom plate of the upper floor, the impact energy and vibration energy is effectively absorbed and dispersed by the interlayer noise prevention material installed between the insulating material and the aerated concrete layer, and at the same time, it is converted into thermal energy and absorbed. there is

In order to achieve the above object, the noise prevention material between floors of the apartment house of the present invention is a plate-shaped body 110 having a thickness (T) of 1.0 mm to 2.5 mm using rubber having excellent elastic restoring force and vibration damping characteristics as the main raw material. And, a first reinforcing part 120 having a thickness of 2mm to 3mm at the lower portion of the body 110 and protruding a plurality of protruding portions at regular intervals, and an inclined surface 131 protruding from the lower portion of the first reinforcing portion 120 ) and a second reinforcing part 130 protruding to a height of 4 mm to 5 mm, and a cylindrical support protrusion formed to protrude downward having a height of 4 mm to 7 mm below the second reinforcing part 130 It is achieved by being composed of (140).

On the other hand, since the support protrusion 140 has a diameter of 3.5 mm to 4.5 mm, the second reinforcing part 130 formed on the upper part of the support protrusion 140 absorbs the remaining shock energy and vibration energy efficiently. It turns out that it is more preferable to let it be discharged to the outside while converting it into thermal energy.

In addition, it should be noted that the first reinforcing part 120 is formed in the horizontal and vertical directions of the bottom surface of the body 110 , respectively.

According to the present invention, a body having its own elastic force of rubber having excellent elastic restoring force and vibration damping characteristics, a first reinforcing part formed under the body, a second reinforcing part formed under the first reinforcing part, and the second Even when an instantaneous load (a bang-type instantaneous load, which is a method of measuring a weight impact sound) of about 4,500 N/m2 is applied by the cylindrical support protrusion formed in the reinforcing part, the impact energy and vibration energy are effectively sequential As it is absorbed and converted into thermal energy at the same time, there is an effect of preventing transmission to the lower layer.

On the other hand, since only the lower end of the support protrusion, which is formed with a diameter of 3.5 mm to 4.5 mm on the upper surface of the concrete slab, is in contact, the impact energy and vibration energy generated in the upper layer are effectively converted into thermal energy and absorbed, so that the upper layer There is an effect that the occupants living downstairs do not feel any discomfort due to the impact load and noise generated from the

In addition, according to the present invention, as the support protrusion is supported by the first reinforcing part and the second reinforcing part, the stable standing state is maintained between the upper surface of the concrete slab and the lower part of the body, and thermal energy introduced between the body and the concrete slab is effectively absorbed and dispersed, so that the occupants living in the lower floor do not feel uncomfortable due to the impact load and noise generated in the upper floor, which is a very useful invention.

The interlayer noise prevention material of the apartment house of the present invention is made of rubber having excellent elastic restoring force and vibration damping properties as a main raw material, and a plate-shaped body 110 having a thickness (T) of 1.0 mm to 2.5 mm, and the body 110 A first reinforcing part 120 having a thickness of 2 mm to 3 mm at the lower portion and protruding at regular intervals at regular intervals, and an inclined surface 131 protruding to the lower portion of the first reinforcing part 120, and having a height of 4 mm to 5 mm It is composed of a second reinforcing part 130 protruding from the bottom, and a cylindrical support protrusion 140 having a height of 4 mm to 7 mm below the second reinforcing part 130 and protruding downward.

Meanwhile, the support protrusion 140 has a diameter of 3.5 mm to 4.5 mm.

In addition, the first reinforcing part 120 is formed in the horizontal and vertical directions of the bottom surface of the body 110, respectively.

The effect of the construction of the inter-floor noise prevention material 100 of the present invention, which is the present invention, configured as described above will be examined.

4 is a cross-sectional view of an interfloor floor slab of a general apartment, etc., on the concrete slab 500, the insulating material 200 made of the foaming resin such as the prevention material 100 and the EPS material is sequentially seated and provided thereon. The concrete 300 and the finishing mortar 400 are sequentially constructed.

In this floor slab construction process, the interlayer noise prevention material 100 of the present invention not only exhibits a buffering ability by its own elastic force, but also air in the space 600 between the lower part of the body 110 and the concrete slab 500 Compression occurs and the air cushion cushioning capacity is exhibited.

That is, when an instantaneous load (a bang-type instantaneous load, which is a method of measuring a weight impact sound) is applied to the floor plate of the upper floor about 4,500 N/m2, the impact is first transmitted to the insulating material 200 and the shock energy and vibration energy are absorbed Then, it is transmitted to the preventive material 100 of the present invention, and the shock energy and vibration energy transferred from the insulating material 200 are secondary attenuated by the elastic force of the body 110 of the preventive material 100 itself. Impact energy and vibration energy are absorbed and dispersed.

On the other hand, the remaining shock energy and vibration energy absorbed by the body 110 is absorbed while being attenuated by the first reinforcing part 120 formed on the bottom surface of the body 110 again, and the first reinforcing part 120 . The remaining vibration energy and impact energy absorbed by the second reinforcing part 130 are absorbed through the second reinforcing part 130 and at the same time converted into thermal energy, the space formed between the bottom surface of the body 110 and the upper part of the concrete slab 500 through the inclined surface 131 ( 600), and the thermal energy introduced into the space 600 is widely dispersed and dissipated.

On the other hand, the remaining vibration energy and impact energy absorbed by the second reinforcing part 130 are finally transferred to the support protrusion 140, and the vibration energy and septal energy transferred to the support protrusion 140 are the concrete slab ( 500) as it moves in the lower direction of the support protrusion 140 in contact with the upper surface of the lower end, vibration energy and impact energy are finally absorbed and converted into thermal energy at the same time between the lower surface of the body 110 and the upper part of the concrete slab 500 Discharge is made to the space portion 600 formed in the space portion 600, the thermal energy introduced into the space portion 600 is widely dispersed and dissipated.

In addition, when the entire amount of impact energy and vibration energy is not absorbed by the support protrusion 140, the diameter of the support protrusion 140 is formed within 3.5 mm to 4.5 mm and is in contact with the lower end of the concrete slab 500. will be done

At this time. Since the support protrusion 140 has a diameter of 3.5 mm to 4.5 mm, the minimum vibration and impact energy is transmitted while absorbing and dispersing the impact energy and vibration energy, and the vibration energy and noise caused by the impact energy are generated to the lower layer. will prevent

On the other hand, the support protrusion 140 is supported by the second reinforcing portion 130 having an inclined surface formed at the upper end and the first reinforcing portion 120 formed in the upper portion of the second reinforcing portion 130 and having a diameter of 3.5 mm to Even in a state of 4.5 mm, the lower end is stably maintained in contact with the upper surface of the concrete slab 500.

Due to this, the state in which the space portion is stably formed between the bottom surface of the concrete slab 500 and the body 110 is maintained, and in the space portion 600, the body 110 and the first reinforcing portion 120 and the second reinforcing portion are maintained. As the vibration energy and the septum energy are absorbed in 130 and the support protrusion 140, the converted thermal energy is widely dispersed and destroyed.
