More particularly, the present invention relates to a soundproofing material for building, and more particularly, to a soundproofing material for building, which is installed on an upper part of an interlayer slab of a multi-story building such as an apartment, absorbs noise and shocks to prevent noise, impact, To a flooring sound insulating material for construction.

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.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of a constructional layered sound insulating material according to an embodiment of the present invention, and FIG. 2 is a front view of FIG. 1.

1 and 2, the following will be described.

For reference, it is difficult to show a single module of a building-floor sound insulating material in the drawing, only a part thereof is shown.

The size of the module may vary depending on the work environment and sound insulation material installation standards, but it is preferable to manufacture the module with a width of 900 mm and a length of 1,800 mm on the basis of the first buffer member.

The present invention relates to a sound insulating material which attenuates noise and vibration generated by being installed between layers, comprising: a first cushioning member (100) having a concave portion and a convex portion formed on one side thereof in a concave / convex portion; The upper surface of the first buffer member 100 is coupled to the lower surface of the first buffer member 100 in a flat surface shape having a predetermined thickness and a plurality of coupling holes 210 are formed at regular intervals in the longitudinal direction of either the horizontal or vertical direction A second buffer member 200; And a third buffer member 300 coupled to the lower surface of the first buffer member 100 through the fastening hole 210. As shown in FIG.

It is preferable that the material of the first cushioning member 100 is made of neoprene and the material of the second cushioning member 200 is made of the PE foamed foam and the material of the third cushioning member 300 is made of EVA.

The first cushioning member 100 is made of a neoprene which is made by compression, so that the strength is excellent and the overall strength of the building-floor sound insulating material is improved.

Meanwhile, in order to enhance the sound insulation effect, it is necessary to secure an empty space over a certain space. The hollow space generated due to the concavo-convex portion, in particular, the concave portion is formed by the shock, vibration and noise (hereinafter, It is used as a space for attenuation effect.

As shown in FIG. 1, the second buffer member 200 is formed with a fastening hole 210 at regular intervals.

Although the second buffer member 200 is shown as being integrally formed on the drawing, it may be formed in a prefabricated structure and attached.

However, it is preferable to fabricate them integrally for the convenience of production, and it is made of PE foam foam, and the sound insulation effect is very excellent.

However, when only the second cushioning member 200 is constituted, the PE foam foam can not withstand the upper load due to the characteristics of the foam foam, so that the sound insulation effect is deteriorated.

Therefore, the additional structure of the third cushioning member 300 to be described below can make the PE foam foam sound insulation effect, which is the core of the present invention.

The third cushioning member 300 is made of EVA, and its upper surface is attached to the lower surface of the first cushioning member 100 through the fastening hole 210.

EVA has a disadvantage of high sound insulation effect but high production cost, and it has a characteristic that it is maintained at a constant thickness when it is compressed by a certain thickness.

FIG. 3 is a bottom view of an embodiment of a building-floor sound insulating material according to the present invention, and FIG. 4 is a sectional view showing the state of use of the building A-A portion of FIG.

Fig. 3 shows a bottom view of the combined state of Fig. 1. Fig.

Referring to FIGS. 3 and 4, the following will be described.

The third cushioning member 300 is formed on the upper surface thereof with a coupling convex portion 310 which is coupled to the odd-numbered or even-numbered concave portion of the concavo-convex portion of the first buffer member 100 in correspondence with the shape and size of the concave portion .

A first support convex portion 320 is formed on the lower surface of the third cushioning member 300 for each opposed position of the concave convex portion 310 and a first support convex portion 320 is formed on one side or both sides of the first concave convex portion 320, The second support convex portion 330 is formed to be longer than the first support convex portion 320 by a predetermined length.

In addition, the third buffer member 300 is formed to be thicker than the thickness of the second buffer member 200 (upper and lower thickness with reference to Fig. 4).

3, the first supporting convex 320 and the second supporting convex 330 are only partially described. However, the first supporting convex 320 and the second supporting convex 330 are not limited to the above- Are sequentially formed successively in the rightward direction, and the configuration thereof can be seen in more detail through Fig. 2 and Fig.

As shown in FIG. 4, the present invention is provided between a foamed concrete in which a pipe 30 is formed and a mortar layer 20 and a slab 10 so as to attenuate noise generated between the slabs, The second support convex portion 330 attenuates noise at the time of an impact or an impact.

Thereafter, after the noise is attenuated in the second cushioning member 200, the noise is reduced in the first supporting convex portion 320, the noise is again reduced in the first cushioning member 100, and finally, The noise is completely attenuated in the empty space formed inside the sound insulating material and is extinguished.

The principle of sound insulation of the present invention will be described in more detail as follows.

The second support block 330 is formed of EVA, and when pressed to a predetermined thickness, is not further compressed, the second support block 330 maintains a predetermined thickness.

The lower surface of the second support block 330 pressed to a predetermined thickness has the same height as the lower surface of the second buffer 200 made of the PE foam foam from the slab 10, The excellent sound insulation effect of the PE foam foam is maintained without being squeezed by the second support block part 330. (The PE foam foam is less likely to have a sound insulation effect as it is compressed)

In addition, when a heavier load is applied or an impact occurs, the first support block portion 320 is secondarily compressed to a predetermined thickness secondarily to the second support block portion 330.

However, since the second support block 330 is compressed to a maximum value and is not further compressed, the first support block 320 is maintained at a constant thickness, so that the compression force applied to the first support block 320 is not large.

The fastening block 310 is coupled to the recess of the first cushion 100 and the fastening block 310 and the first supporting block 310 320).

In addition, the thickness of the second buffer member 200 due to the compression is not greatly affected by the compression thickness of the third buffer member 300, and it is possible to maximize the sound insulation effect of the PE foam foam.

In other words, the second buffer member 200 and the third buffer member 300 each have an excellent sound insulating effect, and the sound absorbing effect of the third buffer member 300 due to the pressing thickness retention force of the third buffer member 300 The effect of the second buffer member 200 and the third buffer member 300 can be further enhanced by the synergy effect between the second buffer member 200 and the third buffer member 300.

In the present invention, both the second buffer member 200 and the third buffer member 300 are made of EVA and the material of the second buffer member 200 and the third buffer member 300 can be changed. However, since the price of the EVA is high, It is preferable that the third buffer member 300 is made of a PE foam foam, and the third buffer member 300 is made of EVA.
