The present invention relates to an interlayer noise vibration prevention device of a building, and more particularly to an interlayer noise vibration prevention device of a building capable of concentrating vibrations by concentrating vibrations while increasing a dust layer.

In multi-unit houses and buildings such as apartments, living spaces or work spaces are separated up and down with concrete slabs in between. As a result, the noise or vibration generated from the upper floor is transmitted directly to the lower floor, which often causes great disruption to residential life and work. In order to prevent this, in recent years, various structures for reducing noise between floors of buildings have been studied, and some of them are described below.

Korean Registered Utility Model Publication No. 337780 discloses an example of a shock absorbing sound absorbing member, and its cross-sectional structure is shown in FIG. As shown, the conventional sound insulation member 100 is laminated on top of the first fibrous material layer 110 and the first fibrous material layer 110 made of synthetic resin, but made of synthetic resin and irregularly bent Of the three-dimensional network mat layer 120 forming a plurality of mountains and valleys, the second fiber material layer 130 made of a synthetic resin laminated on top of the three-dimensional network mat layer 120, and the second fiber material layer 130 The third fibrous material layer 140 made of a synthetic resin laminated on top, the styrofoam 150 stacked on the third fibrous material layer 140, and the shock absorbing sound insulating sheet 160 laminated on the styrofoam 150 Consists of. Here, reference numeral 30 denotes a finish mortar, 32 denotes a heating pipe, and 20 denotes aerated concrete. In addition, the sound insulation member 100 is disposed on the concrete slab 10.

On the other hand, Korean Utility Model Publication No. 312358 discloses a "layer interlayer dustproof material laminated structure for building", the cross-sectional structure is shown in FIG. As shown, the conventional interlayer dustproof material 11 is buried between the floor slab 1 of the building and the foam concrete 12 and the finishing mortar 18 to reduce the interlayer noise caused by the floor impact. After the irregularities 13 are formed and the air layer 14 is formed at regular intervals at the bottom and the high-density layer 15 made of synthetic rubber damping sheet is provided, the lower or upper and lower ends of the high-density layer 15 are centered. The multi-density layer 16 composed of crosslinked PE foam and the low density layer 17 composed of non-crosslinked PE foam are thermocompressed to form a multilayer structure.

However, in such a conventional building floor noise vibration prevention structure, due to the strength problem, the air layer can not be wide, there is a disadvantage that it is difficult to control the vibration is dispersed in a large area.

The present invention has been made to solve the above problems, an object of the present invention is to provide an inter-layer noise vibration prevention of the building that can increase the dust-proofing effect by maintaining a relatively large air layer in the vicinity of the upper surface of the slab.

In addition, it is an object of the present invention to provide an interlayer noise and vibration prevention device of the building to induce the concentration of the vibration unit and at the same time prevent the relative shaking to concentrate the dust-proofing effect, and also to effectively control the vibration.

In order to achieve the above object, the inter-layer noise vibration preventing device of the building according to the present invention,

A lower dustproof part in which a plurality of rubber plates and resin plates are laminated;

An upper cover part disposed to cover an upper surface of the lower dustproof part;

It is configured to include,

A protrusion protruding downward is formed on an upper inner surface of the upper cover part, and a rubber dustproof plate 610 is attached to an upper surface of the lower dustproof part so as to face the protrusion.

A locking protrusion is formed on an outer circumferential surface of the lower dustproof part, and a guide groove is formed on an inner surface of the upper cover part, and it is preferable to be coupled to each other by pressing and rotating the upper cover part.

In addition, when the upper cover portion and the lower dustproof portion are coupled, the protrusion and the rubber dustproof plate are preferably in contact with each other.

In addition, the locking projection is preferably formed on the outer surface of the resin plate.

In addition, the rubber dustproof plate is preferably attached on the resin plate.

On the other hand, it is preferable that at least one of the rubber plates is formed of a plurality of bands having different diameters.

In this case, a space portion is formed between the plurality of bands, and the band-shaped rubber plate may have a hole formed along the circumferential direction.

The lower sound absorbing material may be attached to the bottom surface of the lower dustproof part.

In addition, an upper sound absorbing material may be attached to an upper surface of the upper cover part.

Moreover, it is preferable that the adhesive bond layer is formed in the upper surface of the said upper cover part.

Hereinafter, with reference to the accompanying Figures 3 to 7 will be described in detail a preferred embodiment of the present invention.

As illustrated, the floor noise vibration preventing device 1000 of the building according to the present embodiment includes a lower dustproof part 600 in which a plurality of rubber plates 650 and a resin plate 660 are stacked, and the lower dustproof part ( The upper cover part 700 is disposed to cover the upper surface of the 600. In this case, the inner side surface of the upper cover portion 700 and the outer side surface of the lower dustproof portion 600 may be separated.

Here, the resin plate 660 prevents the buckling phenomenon due to the vertical load of the rubber plate 650 attached to the upper or lower side, and serves to suppress the lateral expansion of the rubber plate 650 during compression deformation.

At this time, the laminated rubber plate 650 is preferably made of the same material, and serves to block the vibration transmitted from the upper cover portion 700. Of course, you may have slightly different physical properties.

In the present embodiment, the rubber plate 650 and the resin plate 660 is composed of three layers, but the number of stacked layers can be arbitrarily adjusted.

On the other hand, the upper cover portion 700 is made of a resin, the upper inner surface is formed with a protrusion 710 protruding downward, the upper surface of the lower dustproof portion 600 and the protrusion 710 and A rubber dustproof plate 610 is attached so as to face each other. In addition, it is advantageous in strength that the rubber dustproof plate 610 is attached on the resin plate.

A locking protrusion 620 is formed on an outer circumferential surface of the lower dustproof part 600, and a guide groove 720 is formed on an inner surface of the upper cover part 700. Accordingly, the upper cover part 700 may be coupled to each other so as not to fall out by rotating the upper cover part 700 while being pressed against the lower dustproof part 600. To this end, the guide groove 720 is formed of a "c" shape, the locking projection 620 may be coupled along the guide groove 720. In this case, the locking projection 620 is preferably formed on the outer surface of the resin plate 660.

As such, when the coupling between the upper cover 700 and the lower dustproof part 600 is completed, the protrusion 710 and the rubber dustproof plate 610 may be in contact with each other, but are spaced apart at a slight interval. You may be. This is because, when a relatively large load acts on the upper surface of the upper cover part 700, the rubber layer of the lower dustproof part 600 comes into contact with each other while being compressed.

Furthermore, as shown in FIG. 4, at least one of the rubber plates 650 is formed of a plurality of bands having different diameters, and is cut in two or more portions along the circumferential direction, thereby providing a space portion between the plurality of bands ( 654 and the through hole 656 in the incision is preferably formed.

Of course, as shown in FIG. 6, the through hole may not be formed and may be configured as a simple circular strip.

Since the space communicating with the outside is formed by the space 654 and the through hole 656 of the rubber plate 650, it is possible to effectively disperse the noise transmitted from the top. This is an application of the principle of the interference-type soundproof wall that forms the noise reduction region by generating an interference effect due to the phase difference of the sound by the space 654 and the through hole 656.

In addition, the upper sound absorbing material 500 is attached to the upper surface of the upper cover portion 700, it is preferable to absorb the vibration and noise transmitted to the first dustproof opening. The lower sound absorbing material 400 may be a soft high density sponge or a superimposed cloth.

In addition, the lower sound absorbing material 400 is attached to the bottom surface of the lower dustproof part 600, it is good to absorb the vibration and noise lastly transmitted to the slab. The lower sound absorbing material 400 may be a soft high density sponge or a superimposed cloth.

In addition, the adhesive 800 is applied to the upper surface of the upper cover 700, it is preferable to be firmly attached to the upper panel.

According to this configuration, when the dynamic load acts on the actual slab, the primary dust is made by the upper dustproof structure (not shown), and the dust is made by the noise vibration preventing device according to the present invention.

Specifically, as shown in FIG. 7, first, the upper vibration absorbing material 500 is attached to the upper surface of the upper cover part 700 by vibrating the panel 910 and the sound absorbing and insulating material 920. Proceeds in a partially absorbed state.

In addition, the vibration acting on the upper cover part 700 is transmitted to the rubber dustproof plate 610 through the protrusion 710 to make additional dustproofing. At this time, the sharp protrusion 710 is embedded in the rubber dustproof plate 610, the shaking of the upper cover 700 is effectively prevented.

Next, vibration and noise are gradually reduced by the laminated structure of the rubber plate 650 and the resin plate 660 in the lower dustproof part 600.

Finally, final vibration and sound absorption are achieved by the lower sound absorbing material 400 attached to the bottom surface of the lower dustproof part 600.

According to the present invention having the above-described configuration, the rubber dustproof plate is attached to the upper surface of the lower dustproof part, and the upper cover part is provided with a protrusion to face the rubber dustproof plate, so that the vibration is stuck to each other during vibration, so the effective dustproof effect You can expect.

In addition, since the air layer is widely distributed around the noise vibration preventing device according to the present invention, the buffering effect is further increased.

In addition, according to the present invention, since the upper cover portion can be rotated to be firmly installed on the lower dustproof portion, there is also an advantage in that the manufacturing and assembly are easy.
