The present invention relates to a soundproofing member, and more particularly, to an interlayer dustproofing member which prevents breakage of a plurality of irregularities formed in the dustproofing material, and is provided with additional soundproofing means to maximize soundproofing function.

In general, floor impact sounds generated in residential buildings divided into multiple floors such as townhouses, multi-family houses and apartments are caused by the vibration of the floor structure caused by the impact applied to the floor during the fall or movement of an object or when a person walks. As such noise, floor impact sounds are again classified into light sounds such as door opening and closing, shoehorns of stairs, doorbells and the like, and heavy sounds such as children's playing sounds and walking barefoot indoors.

Here, the light sound is not a noise that is directly transmitted to the lower part through the inhabited floor, and thus may be blocked by a heat insulating material laminated to the floor, but in the case of heavy sound, the light is directly transmitted to the lower part through the inhabited floor. Therefore, in order to block this, there is a method of increasing the thickness of the slab (slab) in the configuration of the layer forming the laminated configuration.

However, in the case of increasing the thickness of the slab, there is a problem that it is difficult to apply to a multi-storey residential building because the load between floors is greatly increased.

As an improvement of such a problem, FIG. 1 is a cross-sectional view of an interlayer sound insulation member that is commercially available.

As illustrated, the dustproof material 2 having irregularities formed at predetermined intervals on the lower surface thereof is laminated on the upper side of the slab 1, and the lightweight concrete 3 is laminated on the upper side of the dustproof material 2, and the lightweight concrete 3 At the upper side of the) is a finish mortar 4 is inserted into the circulation pipe 5 for the heating is laminated.

Thus, the conventional interlayer soundproofing member is constructed between the slab 1 and the light-weight concrete (3) is provided with a dustproof material (2) formed with irregularities at predetermined intervals between the dustproof material (2) and the slab (1) in the laminated configuration The space S is formed.

Due to this, the heavy sound transmitted to the finishing mortar 4 and the light concrete 3 through the bottom surface of the room is transmitted through the space S when delivered to the slab 1 through the dustproof material 2. At this time, the heavy sound that is transmitted to the dustproof material 2 through the light concrete 3 is a low frequency or long sound that is moved to the space S through the dustproof material 2 having a long wavelength is soundproofed when passing through the space S. By dispersing at high frequency having a short wavelength (or sound absorption) to be easily transmitted to the slab 1, some of the sound is absorbed in the slab 1 and only the remaining part passes through the slab 1.

However, in the conventional interlayer soundproofing member, since the load of the finishing mortar 4 and the light concrete 3 is concentrated on the part (point) where the unevenness formed on the lower surface of the slab 1, the dustproof material 2 is in contact with the long-term use, It causes the problem that the uneven part of 2) is broken. As a result, the space S formed between the dustproof material 2 and the slab 1 disappears, and the dustproof material 2 and the slab 1 come into contact with each other face to face and have a low frequency weight sound having a long wavelength due to dispersion. There is a problem that the sound insulation function is remarkably inferior because it does not provide a function to convert the high frequency heavy sound having a short wavelength.

In addition, there is a problem that the sound insulation function is lowered because it does not provide additional sound insulation means.

The present invention has been made to solve the above problems, an object of the present invention is to provide a cushioning means so that a plurality of irregularities formed on the lower surface of the dustproof material is not damaged, thereby maintaining a constant sound insulation function at all times even during long-term use To provide a soundproof member.

Another object of the present invention is to provide an interlayer soundproofing member with additional soundproofing means by installing a plurality of members constituting the interlayer soundproofing member to be installed in a plurality, when installed on the floor so that a predetermined space is formed between adjacent members. .

Hereinafter, the configuration and operation of embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a cross-sectional view of the interlayer soundproofing member of the present invention, Figure 3 is a partially enlarged cross-sectional view showing a state of use after the installation of the interlayer soundproofing member of the present invention.

As shown, the interlayer soundproofing member of the present invention is laminated on the slab 10 and the upper side of the slab 10, a plurality of shock absorbing material which is installed to be spaced at a predetermined interval to form a plurality of spaces ( 20) and a plurality of anti-vibration materials 30 which are formed to be stacked on the upper side of the shock absorbing material 20, are formed to have a plurality of concavities and convexities formed on the lower surface thereof, and are spaced at predetermined intervals to form a plurality of spaces S. The heat insulating material 40 laminated on the upper side of the dustproof material 30, the lightweight concrete 50 laminated on the upper side of the heat insulating material 40, and the finishing mortar 60 installed on the upper side of the lightweight concrete 50. )

The buffer material 20 has a continuous bubble (open cell) structure, the material is a high density of 50 ~ 200kg / ㎥ and has a heat insulation effect of about 0.00300 ~ 0.00500㎉ / mhr ℃ polyurethane, expanded polypropylene (EPP) , Foamed ethyl vinyl acetate (EVA), polyethylene foam (PE foam), non-woven fabric, any one of glass wool can be used.

The material of the dustproof material 30 may be positioned between the heat insulating material 40 and the buffer material 20 to support the load of the finishing mortar 60 and the light concrete 50 and at the same time may use a high-density plastic having a predetermined or more durability. have.

The material of the insulation 40 is a high density of 50 ~ 200kg / ㎥ and having a heat insulation effect of about 0.00200 ~ 0.00400m / mhr ℃ as polyurethane, expanded polystyrene (EPS), extrusion board (ExPS), expanded polypropylene ( EPP), foamed ethyl vinyl acetate (EVA), polyethylene foam (PE foam), vinyl chloride foam (PVC foam) can be used.

The plurality of spaces S formed by being spaced apart from the plurality of shock absorbing materials 20 and the plurality of irregularities formed on the bottom surface of the dustproof material 30 are disposed to be staggered with each other.

The operation of the present invention configured as described above will be described.

As described above, the shock absorbing material 20 constituting the interlayer soundproofing member of the present invention constituted is installed separately into a plurality when installed on the floor, but the other adjacent member (for example, adjacent to the shock absorbing material 20) Between the cushioning material) is provided spaced apart a predetermined interval so that a predetermined space (S) is formed.

In addition, the plurality of vibration isolators 30 are also spaced apart by a predetermined interval so that a predetermined space S is formed between a plurality of adjacent members in the same manner as the above-described mounting structure of the buffer member 20.

Due to this, the heavy sound transmitted radially through the finishing mortar 60, light weight concrete 50, the heat insulating material 40, the dustproof material 30 and the buffer material 20 at the bottom of the room is the finishing mortar 60, light weight Some of the sound insulation (or sound absorption) while being delivered to the concrete 50 and the heat insulating material 40.

Subsequently, the weight sound transmitted radially to the dustproof material 30 is a space existing between the dustproof material 30 and the other dustproof material 30 when the soundproof material 30 is transferred from the dustproof material 30 to another adjacent dustproof material 30 ( The low frequency heavy sound having a long wavelength because it is transmitted through S) is a high frequency heavy sound having a short wavelength that is easy to be soundproofed (or absorbed) due to the flow resistance corresponding to the viscosity of air present in the space S. Is converted to sound insulation.

In addition, the heavy sound transmitted to the shock absorbing material 20 through the anti-vibration material 30 is converted into the low sound heavy sound again in the space S formed by the unevenness between the dustproof material 30 and the shock absorbing material 20. Here, the space S formed by the unevenness between the dustproof material 30 and the shock absorbing material 20 is not converted to high frequency because the space S has a wider space S than the space S formed between the plurality of dustproof materials 30. Most of the low frequency heavy weights are converted so that each member constituting the interlayer soundproofing member of the present invention is easily soundproofed (or sound absorbed).

Referring to FIG. 3, the anti-vibration material 30 constituting the interlayer soundproofing member of the present invention is in contact with the upper side of the shock absorbing material 20, but a plurality of irregularities formed on the bottom surface of the anti-vibration material 30 are elastic surfaces of the shock absorbing material 20. The surface area where the plurality of unevennesses of the dustproof material 30 come into contact with the buffer material 20 is widened so that the load of the finishing mortar 60 and the light concrete 50 is in contact with the plurality of unevennesses of the bottom surface of the dustproof material 30. Because it is dispersed in the (surface), even if used for a long time to prevent a plurality of unevenness of the heat insulating material and the dustproof material 30 is not damaged, the space (S) is always maintained even during long-term use to maintain a constant sound insulation function.

And since the buffer material 20 has a continuous bubble (open cell) structure, the lower layer of the low frequency transmitted sound is absorbed or converted into high frequency heavy sound so that the slab 10 can be easily soundproofed (or sound absorbed). Minimize the amount of noise that is a heavy sound transmitted to the system.

In addition, due to the plurality of spaces S formed to be spaced apart from each other, the plurality of shock absorbing materials 20 may convert some of the low frequency heavy sound into high frequency heavy sound to finally transmit only the minimum amount of heavy sound to the slab 10. By maximizing the sound insulation effect.

Here, the plurality of irregularities formed on the lower surface of the dustproof material 30 are alternately disposed with the spaces S formed between the plurality of shock absorbing materials 20, thereby damaging the unevenness of the dustproof material 30 and both ends of the plurality of shock absorbing materials 20. To be minimized.

 As described above, the present invention provides a constant sound insulation function even when used for a long time by providing a buffer means at the bottom to prevent breakage of a plurality of irregularities formed on the lower surface of the dustproof material so as to prevent the recession of the space formed between the unevenness of the slab and the dustproof material. Maintains the effect that keeps.

In addition, when installing some members constituting the inter-layer sound insulation member on the floor is installed in a plurality of pieces to install a predetermined space between the adjacent members by forming a plurality of spaces to further maximize the sound insulation or sound absorption of the noise have.
