Description

{INTERLAYER SOUND INSULATION MATERIAL}

More particularly, the present invention relates to a soundproofing material for building, and more particularly, to a soundproofing material for building, which is installed at an upper part of an interlayer slab of a multi-story building such as an apartment, absorbs noise and shocks to prevent noise, shock, (Hereinafter referred to as " acoustic attenuator ").

Generally, apartment houses and villas, such as multi-storey buildings, are built in multi-storey buildings. However, such multi-storey buildings generate interstory noise between the upper and lower floors, resulting in many problems.

Accordingly, although the noise transmission can be minimized by increasing the spacing of the floor concrete (slab) forming the boundary between the slabs, in such a case, the number of the floors of the apartment building, which is constructed within a limited height, Thickness expansion is not considered in the art.

Therefore, when building a multi-storey house, it is used as a soundproofing system to block the impact and noise of the upper floor. It is used to put air-cooled concrete, which acts as a sound insulation and interlayer sound insulation, It has been installed and finished by finishing.

The foamed concrete is a product that mixes water and air into cement and cures it after curing. It has a very high strength and a very low specific gravity. It is a floating material in water and its thermal conductivity is very low, so it is excellent as an insulation product. It is excellent.

In addition, in some cases, a sound absorbing plate having a sound absorbing member mounted on its bottom surface is widely used so as to relieve an impact by lowering the impact to the bottom, and an inner groove is formed in the bottom surface of the plate body to insert a sound absorbing member made of an elastic spring And a plurality of sound absorbing panels are closely attached to each other in the front, rear, left, and right sides, and are installed at the upper part of the bottom surface of the building.

That is, the foamed cement mortar layer is applied to the upper portion of the sound absorbing plate provided on the bottom surface of the building, and the pipe layer, the cement mortar layer and the finishing material are stacked on the upper portion.

However, when the above-mentioned conventional interlayer noise prevention method is used, the impact vibration generated in the upper layer due to the fine structure of the cement and high strength can not be absorbed by the foamed concrete layer and is transferred to the interlayer slab as it is. Vibration and the like can not be prevented.

In addition, the conventional sound-absorbing plate has a problem that it is expensive because the material is expensive, the installation cost is high due to the difficult installation process, and the construction period is long.

Meanwhile, a sound insulating material for construction has been disclosed in Patent No. 10-0773156.

1 to 3, a description will be made of an embodiment of a building-floor sound insulating material according to the present invention as follows.

According to one embodiment of the present invention, there is provided a soundproofing material for attenuating noise and vibration generated in a space between a first shockproof member 100 and a second shockproof member 100, A second shock-absorbing member 200 coupled to the first shock-absorbing member 100 and a second shock-absorbing member 200 interposed between the first shock-absorbing member 100 and the second shock- (100) and the second shock-absorbing member (200) to attenuate the first shock-absorbing member (hereinafter, referred to as 'noise') of the first shock- And the second impact preventing member 200 are attached to each other so that they are not separated from each other.

The first shock absorber 100 is located at the lower part of the foamed concrete and mortar layer 20 which is located at the upper part and is formed with the pipe 30 and has a plurality of first protrusions 111 and a plurality The first concave portions 110 are formed of the first concave portions 112. [

The shapes of the first convex portion 111 and the first concave portion 112 may have various shapes having a regular pattern.

The second shock-absorbing member 200 is positioned on the upper portion of the slab 10 while being positioned below the first shock-absorbing member 100.

A second concavo-convex portion 210 composed of a second convex portion 211 and a second concavo-convex portion 212 corresponding to the first concavo-convex portion 110 in the upper direction is formed on the upper surface of the second impact- .

The first impact-preventing member 100 and the second impact-preventing member 200 may be made of any one of EPS, neopol, and EVA, and preferably a neopol.

EPS and neo-poles are excellent in strength and improve the overall strength of the sound insulation materials for construction, and EVA has the property of excellent sound insulation effect.

The impact damping member 300 is fastened and fixed by the double-sided attaching member 400 without being joined by another bonding means or fastening means.

The impact damping member 300 may be made of polyester or EVA, preferably made of polyester.

Polyester is most effective in preventing noise, but due to the characteristics of polyester, it is not possible to maintain the noise preventing effect because of the high compression force when composing layered sound insulating material for construction is made of polyester only.

Therefore, as in the present invention, the first and second shock-absorbing members 100 and 200 are disposed between the first and second shock-preventing members 200 and 200, The compressive force of the polyester is lowered and the excellent noise preventing effect is obtained.

The double-sided attachment member 400 may be composed of a crosslinked foamed resin, a PE foamed foam, and an EVA, and is preferably composed of a crosslinked foamed resin.

The upper and lower surfaces of the double-sided attachment member 400 are each formed of a pressure-sensitive adhesive so as to be adhered to each other between the first and second impact-preventing members 100 and 200 so that they are not separated from each other.

Another important point of the present invention is that both the first impact-preventing member 100, the second impact-preventing member 200, and the impact-damping member 300 are fastened through the double-sided attaching member 400 .

This eliminates the need for a complicated process for separate bonding or bonding in the fabrication process and is advantageous in that the end of each of the first recess 112 and / So that the manufacturing process is greatly simplified, the work efficiency is enhanced, and the manufacturing cost is greatly reduced.

That is, it is preferable that the double-side attachment member 400 determines its position and number in consideration of the weight and the like of the building-floor sound insulating material. As shown in FIG. 2, But it is preferable that it is formed at the end portion in order to maintain the continuity of the impact damping member 300.
