When constructing the vibration isolation assembly 1, a plurality of vibration isolation assemblies 1 may be connected in such a way that their edges are in contact with each other, and the plurality of vibration isolation assemblies 1 may be arranged along the same plane.

When the dust-proof assembly (1) is constructed in an apartment complex, a coating layer (3) for waterproofing may be formed on the top of the dust-proof assembly (1). The coating layer 3 may be in the form of a thin film.

When the dust-proof assembly (1) is constructed in an apartment complex, foamed concrete (4) and/or cement mortar (5) may be stacked on the upper side of the dust-proof assembly (1), and the boiler pipe (6) This can be additionally constructed, and the floor surface layer 7 can be formed at the top (see Figure 11).

In addition, when the dust-proof assembly (1) is constructed in an apartment complex, the floor surface layer (7) can be formed on the top of the dust-proof assembly (1) without foamed concrete (4) and/or cement mortar (5). .(see Figure 12)

The floor surface layer 7 may be made of various materials such as wood, plastic, or stone, and may be made of various forms such as flooring, panels, tiles, or flooring.

In the dustproof assembly 1 according to one embodiment, the upper plate 330 forming the panel 300 may be made of polyethylene foam, the middle plate 320 may be made of Styrofoam, and the lower plate 310 may be made of polypropylene corrugated cardboard. It can be done. This panel 300 can form an overall stable structure, and thus the first cap 100 and the second cap 400 can be stably fixed to the panel 300, and As the vibration and noise due to the applied external force progress downward, the vibration and noise can be significantly alleviated in the upper plate 330 and the middle plate 320, and can also be distributed along the horizontal direction while passing through the lower plate 310. You can.

In the panel 300, the middle plate 320 may be thicker than the upper plate 330 and the lower plate 310, and the middle plate 320 is provided with a plurality of intermediate holes 321 repeatedly along the horizontal plane. As the vibration and noise caused by the external force applied from the top of the vibration isolation assembly 1 progress downward and pass through the panel 300, it may be transmitted along the formation direction (horizontal direction) of the panel 300. At this time, the panel ( A plurality of intermediate holes 321 are formed in the middle plate 320 of the panel 300, so that vibration transmitted in various directions along the horizontal surface of the panel 300 is blocked and extinguished as it passes through each middle hole 321, When the vibration passes through each intermediate hole 321, it can be distributed radially around the intermediate hole 321, and the vibration can be effectively dispersed and attenuated.

In this way, the vibration and noise transmitted in the horizontal direction of the panel 300 are further dispersed and dissipated as they pass through the middle hole 321, so that the dispersion and attenuation effects of noise and vibration can be excellently achieved.

In addition, as the vibration and noise caused by the external force applied from the top of the vibration isolation assembly 1 progress downward, it passes through the first noise reduction space 345 and the second noise reduction space 355, and the first noise reduction space 345 ) and is reduced or eliminated in the second noise reduction space 355, and then the first elastic supporter 200, the first noise reduction hole 250, the second elastic supporter 500, and the second noise reduction hole 550. It is further reduced or eliminated through the process.

In the vibration isolation assembly 1 according to an embodiment of the present invention, the second elastic supporter 500 is made softer or harder than the first elastic supporter 200. Accordingly, the first elastic support 200 and the second elastic support 500 may have different elastic moduli and may be elastically deformed into different shapes in response to the same external force.

In one embodiment, the first elastic support 200 may be made of hard rubber and the second elastic support 500 may be made of soft rubber. In another embodiment, the first elastic support 200 may be made of soft rubber and the second elastic support 500 may be made of hard rubber.

Based on the Shore A hardness tester, one of the first elastic support 200 and the second elastic support 500 has a hardness of 70 (±5), and the other has a hardness of 60 (±5). You can.

When the first elastic support 200 is made of hard rubber and the second elastic support 500 is made of soft rubber, the amount of deformation of the second elastic support 500 is greater than that of the first elastic support 200 for the same external force. do. In this case, when an impact is applied from the upper side of the vibration isolation assembly 1, the first elastic support 200 may undergo relatively little elastic deformation and the second elastic support 500 may undergo relatively large elastic deformation, The first elastic support 200 can first absorb strong shocks, and the second elastic support 500 can absorb weak shocks, and shocks of various sizes can be absorbed and dissipated, and can absorb and dissipate a wide range of shocks. Vibration attenuation can be achieved.

According to the vibration isolation assembly 1 according to an embodiment of the present invention, when vibration and noise due to impact are transmitted to the first elastic support 200 and the second elastic support 500, the first elastic support 200 and the second elastic support 500 2 It may be attenuated and extinguished in different ways in the elastic support 500, and the vibration is attenuated while one of the first elastic support 200 and the second elastic support 500 absorbs a relatively strong shock, and the other one absorbs a relatively strong shock. Vibration can be attenuated by absorbing relatively weak shocks. In addition, the pattern of vibration damped while passing through the first elastic support 200 and the pattern of vibration damped while passing through the second elastic support 500 may appear different from each other, and the dispersion and extinction of vibration and noise can be easily achieved. It is possible to provide a vibration-proof assembly (1) for floors with excellent noise and vibration reduction effects.

Among the vibrations and noises transmitted from the top to the bottom of the vibration isolation assembly 1, the vibrations and resulting noises passing through the area immediately above the first elastic supporter 200 (first area A1) will be described.

Vibration passing through the first area A1 is not directly transmitted to the first cap 100 or the first elastic support 200, and most of it can move to the first noise reduction space 345 located below. And, by passing through the first noise reduction space 345, which is made up of space, the dispersion effect increases and a significant portion disappears.

When a load is applied from the top to the bottom of the first elastic support 200 according to the present invention, a reaction force according to this load acts on the bottom of the first elastic support 200, and in addition, the first elastic support 200 ) is made so that bending stress and shear force act. Due to the action of these forces, the first elastic support 200 elastically deforms and vibrates to disperse external forces, thereby very effectively reducing noise and vibration.

In the first elastic supporter 200 according to an embodiment of the present invention, the first noise reduction hole 250 is formed to be biased toward the upper side of the first elastic supporter 200, and thus the radial direction of the first elastic supporter 200 The thickness (t1) of the upper part (201) may be thinner than the thickness (t2) of the lower part (203). In this case, when a load is applied from the top to the bottom of the first elastic supporter 200, most of the force is applied to the upper part 201 of the first elastic supporter 200 than to the lower part 203 of the first elastic supporter 200. Elastic deformation is achieved, and vibration is distributed in the upper part 201 of the first elastic support 200. In other words, the vibration and noise are dispersed and eliminated in the vibration isolation assembly 1 while minimizing the vibration transmitted to the lower floor.

Since the first noise reduction hole 250 is provided immediately below the upper part 201 of the first elastic support 200, the noise and vibration transmitted downward from the first elastic support 200 are reduced by the first noise reduction hole 250. It passes through the hole 250 and is dispersed and dissipated in the first noise reduction hole 250.

In addition, in the vibration isolation assembly 1 according to an embodiment of the present invention, a first communication channel 115 is provided between the first cap 100 and the first elastic support 200, and the first communication channel 115 The vibration of the transmitted air may move to the lower space (C) of the panel 300. Accordingly, vibration can be distributed and eliminated throughout the entire area of the vibration isolation assembly (1), and an excellent noise and vibration reduction effect can be achieved when an impact occurs on the upper side of the vibration isolation assembly (1).

As described above, the vibration caused by the external force applied from the upper side of the first elastic support 200 can be primarily dispersed and dissipated in the first noise reduction space 345, and can also be distributed through the first noise reduction hole 250. It can be dispersed and destroyed secondarily. Additionally, some of the vibrations may be dispersed and dissipated three times while passing through the first communication channel 115.

In the vibration isolation assembly 1, the second cap 400 has the same shape and coupling structure as the first cap 100, and the second elastic support 500 has the same shape and coupling structure as the first elastic support 200. Since it is composed of a structure, among the vibration and noise transmitted from the top to the bottom of the vibration isolation assembly 1, the vibration and resulting noise passing through the area immediately above the second elastic support 500 are the first elastic support 200 described above. It can be dispersed and destroyed in the same way as in.

That is, among the vibration and noise transmitted from the top to the bottom of the vibration isolation assembly 1, the vibration and resulting noise passing through the area immediately above the second elastic support 500 (fourth area B1) are the second noise reduction. It can be primarily dispersed and extinguished in the space 355, and also secondarily dispersed and extinguished through the second noise reduction hole 550. Additionally, some of the vibrations may be dispersed and dissipated three times while passing through the second communication channel 415.

In this way, according to the floor vibration isolation assembly 1 according to an embodiment of the present invention, vibration and noise generated on the upper side of the vibration isolation assembly 1 can be dispersed and extinguished while passing through sequential spaces.

Among the vibration and noise transmitted from the top to the bottom of the vibration isolation assembly 1, the vibration passes through the upper area (second area A2 and/or third area A3) on both sides of the first elastic supporter 200. and the resulting noise are explained.

Some of the vibration passing through the second area A2 and/or the third area A3 may be transmitted to the lower side of the panel 300.

The interior of the lower plate 310 forming the panel 300 is provided with a horizontal passage 314 in the horizontal direction, and this horizontal passage 314 is formed over the entire area of the panel 300. The lower side of the panel 300 Since the transmitted vibration can be distributed over the entire area of the panel 300, vibration and noise can be reduced and eliminated very effectively.

Meanwhile, some of the vibrations passing through the second area A2 and/or the third area A3 may be transmitted toward the first cap 100 and the first elastic support 200. At this time, a significant portion of this vibration can move to the first noise reduction space 345 and the middle hall 321 located on the side, and the first noise reduction space 345 and the middle hall 321 made up of spaces. By filtering, the dispersion effect increases and a significant portion disappears. In addition, the vibration transmitted toward the first cap 100 through the portion where the panel 300 and the first cap 100 are in direct contact is also the first elastic supporter 200 and the first noise reduction hole 250 mentioned above. And it can be dispersed and extinguished by the first communication channel 115.

In the vibration isolation assembly 1, the second cap 400 has the same shape and coupling structure as the first cap 100, and the second elastic support 500 has the same shape and coupling structure as the first elastic support 200. Since it is composed of a structure, among the vibration and noise transmitted from the top to the bottom of the vibration isolation assembly 1, the upper area (fifth area B2 and/or sixth area B3) on both sides of the second elastic supporter 500 )) Vibration and resulting noise can be dispersed and dissipated in the same manner as in the first elastic support 200 described above.

As described above, according to the floor vibration isolation assembly (1) according to an embodiment of the present invention, the vibration and noise due to the external force applied from the upper part of the vibration isolation assembly (1) progress downward and directly toward the installation surface (B). It is not transmitted, but the first noise reduction space 345, the first cap 100, the first elastic support 200, the first noise reduction hole 250, the middle hole 321, and the horizontal passage 314. It moves through the air, and in this process, vibration and noise are reduced or eliminated.

In addition, as the vibration and noise caused by the external force applied from the top of the vibration isolation assembly (1) progress downward, they are not directly transmitted toward the installation surface (B), but are transmitted to the second noise reduction space (355) and the second cap (400). , it moves through the second elastic support 500, the second noise reduction hole 550, the middle hole 321, and the horizontal passage 314, and in this process, vibration and noise are reduced or eliminated.

Accordingly, the floor vibration isolation assembly (1) according to an embodiment of the present invention can fundamentally block vibration and noise due to external force applied from the upper side of the panel (300) from being transmitted directly to the installation surface (B). do.
