FIG. 2 is a view illustrating an example in which a planar divided sound insulation structure of a dwelling house according to the present invention is divided and installed in a certain section, and FIG. 3 is a cross- Sectional view.

First, a planar divided sound insulation structure of a dwelling unit according to an embodiment of the present invention is divided into a fixed area and a divided area, It is possible to attenuate the impact efficiently.

That is, the cushioning material board 200 installed in the selected section (a, b) is made thicker than the cushioning material board 200 installed in the unselected section (c), effectively attenuating the impact.

Here, the selected section (a, b) means the corner (a) and the center (b) of the foundation floor 110 and the unselected section c means the remaining part .

The reason and effect of dividing the sound insulation structure into the selected sections (a, b) and the unselected sections (c) will be described in detail with reference to a sound insulation structure described later.

The planar divided sound insulation structure of the apartment house according to an embodiment of the present invention includes a cushioning material board 200, a lightweight foamed concrete 300, a finishing mortar 500, a side cushioning material 600, and a dustproof material 700 do.

In addition, the sound insulation structure is installed in the area of the apartment house divided into a certain area, and the divided area is divided into a predetermined section and dividedly installed.

The cushioning material board 200 is dividedly installed in the selected section (a, b) and the unselected section (c).

The cushioning material board 200 is a light and elastic board having a buffering function and a sound insulating function. The board is not deformed by the load and impact transmitted from the upper part, and is excellent in heat insulation and car sound.

The cushioning material board 200 may also be formed of a material selected from the group consisting of Expanded Polypropylene (EPP), Expanded Polystyrene (EPS), Expanded Polyethylene (EPE), Ethylene Vinyl Acetate (EVA) A material that can function as a cushioning material can be selectively applied to a cushioning material such as an expanded polyolefin (EPO), a polyvinyl chloride (PVC), a soft PVC foam, a urethane foam (sponge), a polyester fiber, Board 200 as shown in FIG.

The cushioning board 200 is installed in each of the selected compartments a and b and the unselected compartment c so that the cushioning board 200 installed in the selected compartment a and b has a non- The cushioning material board 200 is thicker than the cushioning material board 200.

For example, a buffer material board 200 having a thickness of 30 mm is provided at an edge (a) and a center (b) of the bottom floor layer 110 as a selected partition a and b, The cushioning material board 200 of FIG.

On the other hand, the magnitude and the height of the interlayer noise are related to the amplitude.

That is, the smaller the amplitude is, the lower the sound is transmitted, and the larger the amplitude, the louder is transmitted.

For example, when both ends of an elastic rubber band are fixed, the rubber band is repeatedly moved in a repulsive direction. At this time, the rubber band has the largest amplitude in the middle portion, that is, The smaller the amplitude, that is, the smaller the size of the braille, the repetitive motion will be.

Thus, when an impact sound is generated in the bottom floor layer 110, an impact sound having a large amplitude is generated near the center of the bottom floor layer 110 and is transmitted to the upper / lower floor.

When noises and vibrations are generated in the unselected section (c), that is, the side wall surface 121 connected to the bottom floor layer 110 or the side wall surface 122 connected to the bottom floor layer 110, Noise and vibration are transmitted to the upper and lower layers only through the longitudinal side wall 122, thereby transmitting noise and vibration with much attenuation.

On the other hand, in the selected section (a, b), the edge (a) transmits noise and vibration to the upper / lower layer, especially the lower layer, through the transverse side wall 121 and the side wall 122, So that noise and vibration with low attenuation are transmitted.

That is, noise and vibration, which are less attenuated than the unselected section (c), are transmitted to the upper and lower layers in the selected section (a) and (b) in the center (a) and the center (b) of the base bottom layer 110.

Thus, the cushioning material board 200 installed in the selected section a and b is made thicker than the cushioning material board 200 installed in the unselected section c, thereby effectively reducing the noise and vibration generated.

Depending on the design conditions, a waterproof coating material 210 may be attached to the upper surface of the buffer material board 200 to prevent the penetration of moisture.

Accordingly, the damping material board 200 is durable by the waterproof coating material 210, so that the damping material board 200 can be prevented from being broken or broken during construction.

The waterproof coating material 210 is made of a nonwoven fabric or paper having a waterproof function and is attached to the upper surface of the buffer material board 200 when wet concrete is applied. The cushioning material board 200 prevents the penetration of moisture to prevent changes in the physical properties of the cushioning material and the impact sound reduction performance, and suppresses the generation of mold.

The nonwoven fabric is a polypropylene non-woven fabric having a waterproof coating layer. The nonwoven fabric may be provided on the upper surface of the cushioning material board 200 to prevent moisture from penetrating and increase the durability and heat insulation of the cushioning material board 200 .

The lightweight foamed concrete 300 is laid on the upper surface of the cushioning material board 200.

Here, the lightweight foamed concrete (300) is a structure for transferring the load of the upper structure to the ground safely, and means a concrete having a lot of voids produced by mixing chemicals that generate water and bubbles in the cement.

The lightweight foamed concrete (300) is excellent in light weight and heat insulation, and is easy to construct, and is also used as a thermal insulation material under the floor of apartment houses.

The finishing mortar 500 is arranged by arranging the hot water heating pipe 400 on the upper surface of the lightweight foamed concrete 300 and placing it on the flattened concrete pipe 300 so that the hot water heating pipe 400 is flatly closed.

The side cushioning material 600 is made of expanded polyethylene (EPE), and is installed on the wall surface 120 extending on the top surface of the bottom floor layer 110.

According to the design conditions, the side cushioning material 600 may be provided on the inside of the wall surface 120 with a waterproof coating material 210 made of nonwoven fabric or paper having a waterproof function.

Accordingly, when the lightweight foamed concrete 300 and the closed mortar 500 are laid, moisture can be prevented from permeating toward the side cushioning material 600.

The vibration damping material 700 is divided into a living room, a room and a certain area of the kitchen, and is installed between the respective areas, thereby preventing noise and vibration generated in one area from being transmitted to other areas.

Preferably, the dustproof material 700 has a thickness of 80 to 120 mm and a height of 40 to 80 mm, and is formed so as to be in close contact with the hot water heating pipe 400 by forming a groove or a through hole so that the hot water heating pipe 400 can pass therethrough desirable.

And an embossed buffer material board 150.

The air layer 152 is formed in the space formed between the embossments 151 so that when the impact is applied from the upper portion of the embossing 151, The air layer 152 formed on the air layer 152 exhibits elasticity to more reliably absorb the shock.

That is, when an impact is applied from above, the transmitted impact is concentrated on the embossment 151. At this time, since the contact area of the bottom floor layer 110 contacted with the embossment 151 is small, the impact transmitted to the embossment 151 is attenuated and transmitted to the bottom floor layer 110, so that vibration and noise can be reduced. In addition, since the impact transmitted to the air layer 152 formed between the embossments 151 is dispersed, vibration and noise can be more effectively blocked.

The cushioning material board 200 is made of the same material as the embossed cushioning material board 150 and is provided in a portion where the embossed cushioning material board 150 is not provided, that is, in the non-selected portion c.

That is, the embossed cushioning board 150 is installed in the selected sections a and b, and the cushioning board 200 is installed in the unselected section c, thereby effectively attenuating the generated noise and vibration.

Therefore, the embossed cushioning board 150 installed in the selected section (a, b) has better sound insulation performance than the cushioning board 200 installed in the unselected section (c), thereby effectively attenuating noise and vibration.

The mesh network 160 may be constructed such that mesh-like sheets having a mesh network of a certain size are stacked in two layers in different directions to absorb impact and noise transmitted from the upper portion.

That is, the mesh networks 160 are stacked in two layers, so that the mesh networks overlap each other and have a more uniform and stable buffering effect.

According to the design conditions, the mesh net 160 can be made of expanded polyethylene (EPE), and it is a highly charged, independent air conditioner. It is excellent in buffering property, easy to install and excellent in waterproof property and chemical resistance The mesh network 160 may be selectively applied to materials other than expanded polyethylene (EPE).

The mesh network 160 and the cushioning board 200 are jointly installed in the selected section a and b of the bottom floor 110 and the selected partition c and By constructing the cushioning material board 200, the generated noise and vibration are effectively attenuated.
