Description

Anti-vibration panel for reducing noise between floors and a method of constructing an anti-vibration structure using the same{Vibration Isolation Panel}

The present invention relates to the field of dustproofing and soundproofing, and more specifically, it is easy to cut and install, so that it is possible to secure construction convenience, but it also has a high level of dustproofing and soundproofing. How to do.

Due to the change in the architectural structure due to the high-rise of the multi-family house, residents' discomfort is caused by inter-floor noise such as floor impact noise between the houses. In particular, inter-floor noise generated in multi-family houses acts as a social conflict factor that, of course, causes extreme actions due to conflict between neighbors. It is necessary to prepare urgently both institutionally and technically.

Noise may be divided into a solid transmission sound transmitted through a solid and an air transmission sound transmitted through a space such as air according to a transmission path.

Interlayer noise refers to the conversion of solid transmission sounds, such as floors and walls, into air transmission sounds in space. That is, in the multi-family house structure, various living noises on the upper floor are noises transmitted to the lower floor through the walls leading to the upper floor and lower floor.

The types of interlayer noise can be divided into lightweight impact sound and heavy impact sound.

Lightweight impact sound is a floor impact sound caused by a relatively light and hard impact, such as when a small object falls or when furniture is moved. The high-pitched sound transmitted to the lower layer by the lightweight impact sound is characterized by weak impact and short sound duration.

On the other hand, the heavy impact sound is a low-pitched sound transmitted to the lower floor by the sound of heavy and soft impact applied to the floor. Unlike the lightweight shock sound, it has a high impact power and a long sound duration.

In order to disperse and absorb the noise between the floors, an interlayer sound insulation material (interior cushioning material or interlayer sound insulation vibration-proof panel) is currently installed between the floor slab layer and the finished mortar layer during the construction of the apartment.

Use it as a comprehensive concept until each contact is made.

The present invention relates to an anti-vibration panel for reducing noise between floors.

In general, the vibration-proof structure adopts a configuration that reduces vibration transmitted from the upper portion by installing an elastic member (a vibration-proof mount) between the bottom of the anti-vibration panel and the floor slab.

However, since the dustproof panel is generally cut and used in the field, the lighter and easier to cut, the more convenient the construction can be secured.

However, since the anti-vibration panel must secure a certain level of anti-vibration effect, it is difficult to form a light and easy-to-cut material. In addition, when it is formed of a material that is light and easy to cut, there is a problem in that it is difficult to perform work on the upper portion of the anti-vibration panel due to the problem of drooping the panel.

The present invention is to provide a dust-proof panel for reducing inter-layer noise, which improves workability by securing a dust-proof effect of a certain level or more and solving a problem of sagging of a panel while being light and easy to cut to solve the above-mentioned problem.

The anti-vibration panel according to an embodiment of the present invention is installed on a multi-layer structure including the floor slab 1 and the wall 2, and is constructed on the floor slab 1 (FIG. 3).

The anti-vibration panel is basically an extruded insulation 120, a first polypropylene board 110 attached to the upper surface of the extruded insulation 120, and a second polypropylene board 130 attached to the lower surface of the extrusion insulation 120. ).

The extrusion method heat insulating material 120 is called'iso pink', and is abbreviated as XPS as a material made by melting and compressing and foaming raw materials. Because it does not absorb moisture, it is mainly used for the construction of bases and basements of buildings.

In the present invention, the extrusion method heat insulating material 120 is utilized as a core member of a dustproof panel forming a dustproof structure.

Since the extrusion method heat insulating material 120 is a soft material, the first polypropylene board 110 and the second polypropylene board 130 are attached to both sides of the extrusion method heat insulating material 120 to be reinforced (FIG. 2).

Referring to Figure 11, it can be confirmed the physical properties of the dust-proof panel according to an embodiment of the present invention.

In the dustproof panel according to an embodiment of the present invention, a plurality of dustproof mounts 200 are attached to a predetermined area below (FIG. 6).

The anti-vibration mount 200 is a plate-shaped elastic material and serves to reduce vibration transmitted from the upper portion. According to an embodiment of the present invention, the anti-vibration mount 200 may be formed of a polyurethane material.

According to an embodiment of the present invention may further include a support member 140 attached to the bottom of the dustproof panel (Fig. 5, Fig. 6).

Since the anti-vibration panel is generally installed in the entire area of the lower slab 1, the subsequent construction work proceeds with the operator positioned at the top of the anti-vibration panel. In this case, the sagging of the anti-vibration panel may occur, resulting in damage to the anti-vibration panel or damage to the anti-vibration mount 200 under the anti-vibration panel. Accordingly, in order to support the anti-vibration panel when the anti-vibration panel sags, a support member 140 is attached to the bottom of the anti-vibration panel.

The support member 140 is attached to an area where the anti-vibration mount 200 is not attached.

However, when the support member 140 is always in contact with the floor slab 1, the ratio of the noise load transmitted to the anti-vibration mount 200 is reduced, or the behavior of the anti-vibration mount 200 is limited and substantially anti-vibration The same problem may occur as the number of mounts 200 is increased. The anti-vibration effect is because the smaller the installation number of the anti-vibration mount 200, the better the effect is exhibited.

Therefore, as illustrated in FIG. 5, the anti-vibration mount 200 should be installed in contact with the floor slab 1, and the support member 140 should be installed at a predetermined distance from the floor slab 1.

Accordingly, the support member 140 serves to support the anti-vibration panel only when the anti-vibration panel is struck, and is installed spaced apart from the floor slab 1 after the construction is completed, so the behavior of the anti-vibration mount 200 Do not limit.

To this end, the thickness d of the anti-vibration mount 200 should be thicker than the thickness of the support member 140.

Since the anti-vibration mount 200 is not attached to the bottom front of the anti-vibration panel, the anti-vibration space 4 is formed between the anti-vibration panel and the lower slab 1.

That is, an elastic member is placed between the anti-vibration panel and the floor slab, so that an empty space (hereinafter referred to as a'vibration-proof space') is formed in an area where the elastic member is not installed, and the behavior of the elastic member is limited due to the air pressure on the anti-vibration space. Occurs.

According to a conventional study, the reason for the reduction of the anti-vibration effect due to the air in the anti-vibration space 4 was determined as a resonance phenomenon, and an attempt was made to solve the problem of reducing the anti-vibration effect by inserting a sound absorbing material into the anti-vibration space.

However, the humidity of the dust-proof space is increased by the sound absorbing material inserted in the dust-proof space, and the moisture on the dust-proof space is moved to the wallpaper to be installed later, and there are problems such as mold formation on the wallpaper.

Moreover, inserting a sound absorbing material into the dustproof space did not solve the problem of reducing the dustproofing effect.

In the present invention, the reason for the above-mentioned problem was grasped by the air pressure on the dust-proof space, and an experiment was performed to prove this.

That is, since the dust-proof space is sealed by cast-in-place concrete and the upper finishing material placed on the upper part, the air on the dust-proof space cannot be discharged to the outside. In this case, there is a problem that the behavior of the anti-vibration mount due to vibration transmitted from the upper portion is limited by the air pressure on the anti-vibration space, and accordingly, the anti-vibration efficiency due to the behavior of the anti-vibration mount is lowered.

These results can be confirmed through the experimental data attached to FIG. 10. Referring to the experimental data, it was confirmed that the air flow was secured as much as the amount of dynamic deflection depending on the presence or absence of the sealing, and thus it showed a difference depending on the area of the sealing.

The present invention proposes an anti-vibration structure provided with an open anti-vibration space (4) to solve the problem that the air pressure limits the behavior of the anti-vibration mount as the anti-vibration space is closed as described above. In addition, a unique configuration is proposed to facilitate the construction of the anti-vibration structure proposed in the present invention.

The anti-vibration structure according to an embodiment of the present invention is formed on a multi-layer structure including the floor slab 1 and the wall 2, and is installed on the floor on the anti-vibration panel and the anti-vibration panel installed on the floor slab 1 It includes a cast-in-place concrete 500 and a finishing member 300 installed on the cast-in-place concrete 500 (FIGS. 3 and 4 ).

In this case, the ventilation space 3 is formed between the dustproof panel and the wall 2 so that the air on the dustproof space 4 is not closed (FIG. 6).

The ventilation space 30 is connected to the dustproof space 4 formed between the dustproof panel and the floor slab 1.

The dustproof structure according to an embodiment of the present invention may further include a side finishing material 400 installed in the ventilation space 3 for closing the ventilation space 3 (FIGS. 4 and 8 ).

The side finishing material 400 includes a side panel 410 connected to the dustproof space 4 and a finishing panel 420 installed on the side panel 410 (FIG. 8).

The side panel 410 is installed on the side of the anti-vibration panel, the cast-in-place concrete 500 and the finishing member 300, the side panel 410 is pre-installed, and the anti-vibration panel, the cast-in-place concrete 500 and the finishing member (300) ) Is preferable from the viewpoint of convenience of construction.

After the finishing member 300 is constructed, the finishing panel 420 may be installed on the side panel 410. The finishing panel 420 can also serve as a so-called bedboard.

Although the side panel 410 and the finishing panel 420 are installed, vent holes are formed in the side panel 410 and the finishing panel 420 so that the dustproof space 4 and the upper space 5 can communicate.

Specifically, a first vent hole 411 connecting the dustproof space 4 and the upper space 5 is formed in the side panel 410, and the first vent hole 411 and the upper space ( 5) a second vent hole 421 is formed.

In this case, since the air on the anti-vibration space 4 can be moved to the upper space 5, the problem of generating air pressure limiting the behavior of the anti-vibration mount 200 can be solved.

The first vent holes 411 are formed in plural along the longitudinal direction of the side panel 410, and the second vent holes 421 are formed in plural along the longitudinal direction of the finishing panel 420.

The finishing panel 420 may include a front panel 422 mounted on the side panel 410 and a rear panel 423 formed at the rear of the front panel 422 and formed with a second vent 421 ( Figure 7, Figure 8).

In this case, in order to prevent the top of the first vent hole 411 from being closed by the bottom (b) of the rear panel 423, the bottom (b) of the rear panel 423 is located at the bottom of the front panel 422 ( It is preferable to be spaced apart upward by a predetermined interval from a) (FIG. 6).

Accordingly, even if the first vent holes 411 and the second vent holes 421 are not vertically arranged, the dustproof space 4 and the upper space 5 may be connected to ensure convenience of construction.

The cast-in-place concrete 500 may include a lightweight foam concrete layer 210 formed on the dust-proof panel and a mortar layer 220 formed on the lightweight foam concrete layer.

In this case, the buffer board 150 may have a protrusion 152 formed under the panel-shaped panel 151 (FIG. 9).

The buffer board 150 may be formed of EVA (Ethylene-Vinyl Acetate).

Hereinafter, a method of constructing a dustproof structure according to an embodiment of the present invention will be described.

The construction method of the anti-vibration structure according to the present invention is the first step (S100) of installing the anti-vibration panel on the top of the floor slab 1 and installing the side panel 410 between the anti-vibration panel and the wall 2 (S100).
