{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 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.

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.

In addition, the construction stability, such as cracking of the insulation during the construction process, also became a problem.

1 to 3, the constructional interlayer sound insulating material of the present invention will be described as follows.

A heat insulating member (100) having a plurality of grooves (110) formed in a lower portion thereof in the longitudinal direction of either one of a horizontal direction and a vertical direction; A vibration absorbing portion 210 coupled to the groove 110 at a length corresponding to the length of the groove 110 to absorb vibration and noise generated at the upper portion of the vibration absorbing portion 210, A vibration damping part 220 which is formed to be wider than a width of the vibration damping part 220 at a lower part of the vibration damping part 220 to transmit vibration and noise absorbed in the vibration damping part 220 And a vibration dispersing unit 230 for dispersing vibrations and noise transmitted through the vibration dispersing unit 220. And a buffer auxiliary member 300 which is orthogonal to the buffer member 200 and is coupled in the longitudinal direction of the thermal insulating member 100.

The upper part of the heat insulating member 100 is further provided with a waterproof member 400 for preventing the heat insulating member 100 from breaking and preventing water from penetrating the heat insulating member 100.

Preferably, the waterproofing member 400 is made of nonwoven fabric, and the heat insulating member 100 is made of EPS or neopol.

The heat insulating member 100 primarily serves to absorb and attenuate vibration (shock) and noise (hereinafter referred to as 'noise') transmitted from the upper part together with the function of the heat insulating material.

The groove 110 is formed at a predetermined depth from the lower part to the upper part of the heat insulating member 100. The bottom surface of the groove 110 formed on the upper part is flat and the groove 110 is formed on the lower surface of the heat insulating member 100, Both side surfaces leading to the bottom surface may be formed in a right angle, but it is preferable that the side surfaces are inclined in consideration of manufacturing characteristics.

The buffer member 200 serves to absorb and attenuate the noise secondarily, and most of the noise is extinguished in the buffer member 200.

The cushioning member 200 absorbs noise in a wide area of the initial vibration absorbing portion 210 and then receives the noise from the vibration damping portion 220 having a small area and transmits the vibration to the lower portion. And the noise is dissipated.

That is, the noise absorbed by the vibration absorbing part 210 is transmitted to the narrow area of the vibration attenuating part 220, and the noise is canceled in the process of canceling each other.

It is preferable that the thickness of the vibration absorbing portion 210 is smaller than the depth of the groove 110 and the total thickness of the buffer member 200 is greater than the depth of the groove 110.

In addition, the remaining noise that has not completely disappeared is transmitted to the vibration dispersing unit 230 having a larger area than the vibration attenuating unit 220, and is completely annihilated.

That is, the noise canceled by the noise in the vibration damping unit 220 is transmitted to the vibration dispersing unit 230 having a large area and is completely broken down.

Although the vibration dispersing parts 230 are shown as being separated from each other in the drawing, they may be formed in a continuous shape.

The buffer member 200 is preferably made of EVA, urethane or the like.

On the other hand, if the interval between the vibration dispersing units 230 is wide, if the pressure exceeds a predetermined pressure, the heat insulating member 100 may be damaged (broken or cracked) during the construction process.

Therefore, as shown in the figure, the buffering auxiliary member 300 is attached between the vibration dispersing parts 230 in a direction perpendicular to the buffering member 200. [

The buffer member 200 may be attached using an adhesive or the like so as not to fall off the groove 110, but it may be attached using the buffer assistant member 300.

The buffering auxiliary member 300 may be attached to the lower surface of the vibration absorbing portion 210 and the lower surface of the thermal insulating member 100 so that the buffering member 200 is fixed to the thermal insulating member 100, Can be configured.

The buffer assistant member 300 is also used as a fixing means, but is also used as a sound attenuating means for attenuating the secondary attenuated noise in the buffer member 200 in a tertiary manner.

That is, when the buffer member 200 is pressed by the upper pressure, the noise is absorbed and attenuated in the buffer assisting member 300.

The buffer aid 300 is also preferably made of EVA, urethane or the like.

In addition, since the buffering auxiliary member 300 is provided between the vibration dispersing portions 230, it is possible to prevent the thermal insulating member 100 from being damaged even under a constant pressure, thereby improving the stability of the construction.

As shown in FIG. 3, the building-floor sound insulating material of the present invention is formed between foamed concrete and a mortar layer 20 provided with a pipe 30 and a slab 10 to block noise transmitted from an upper layer to a lower layer The waterproof member 400 prevents the water in the upper layer from flowing into the lower portion and prevents the heat insulating member 100, the buffer member 200 and the buffer assistant member 300 from being wetted with water and losing the sound insulating function do.
