Soundproofing board to prevent noise between floors {BOTTOM SOUNDPROOF PANEL}

The present invention is a sound insulation plate structure for preventing the interlayer noise of the multi-layer structure formed by stacking the lower plate and the intermediate plate, the upper plate, the air filling unit is filled between the lower plate and the intermediate plate and the intermediate plate and the upper plate at regular intervals A plurality of plate-shaped air caps are inserted and stacked, and the lower plate, the middle plate, and the upper plate are made of a corrugated plate structure or formed with a plurality of through holes, and a protective plate and a thin film layer on the outer side of the upper plate and the lower plate. It relates to a sound insulation plate structure for preventing the interlayer noise, characterized in that it is further laminated.

In multi-storey buildings such as multi-unit houses, noise between floors is a serious problem, and efforts are being made to reduce it.

The main cause of the noise between floors is the sound generated by children playing or moving things, which are transmitted in the form of vibration and noise.

Such vibrations and noise can be reduced by raising the floor advice, and it is known that the structure can be reduced more effectively by laying a soundproof plate on the slab.

Background Art [0002] A bottom plate for reducing interlayer noise and vibration is conventionally known as a method of stacking plates, forming hollows between sheets, or configuring a honeycomb structure.

The hollow part formed in the soundproof plate is known to reduce the noise and vibration caused by various factors to block the expansion of the excitation at the resonant frequency of the structure and to increase the transmission loss by reducing the influence of air coupling to reduce the noise.

The soundproof vibration proof material having such a member structure has been proposed and used in a wide variety of structures, and various application structures such as filling a sound absorbing material into a space based on such member principle are also known.

Soundproof dustproof material having such a member is proposed and used in a variety of structures, various application structures such as filling the sound absorbing material in the interior space is also known.

For example, the Republic of Korea Utility Model Registration No. 0293443 is perforated through the ventilation holes of the small hole in the upper plate and the lower plate, and through the ventilation holes larger than that in the middle plate material and laminated by combining them so that each ventilation hole irregularly replaced sound insulation Moisture proof board is presented.

However, the dual structure or the laminated structure of the hollow plate as described above is a hard-board structure, and the noise and vibration subtraction due to the impact is not effectively made as it is delivered as it is, as a complement to the bottom plate Although the bottom layer structure is improved by forming a bubble concrete layer before finishing, the overall soundproofing and soundproofing effect is obtained, but the sound absorbing plate itself has a low impact absorption.

As another attempt to improve the shock absorbing properties of the soundproof plate, a soundproof plate having a composite plate structure using rubber or waste rubber is proposed, and Korean Patent Laid-Open Publication No. 1998-084997 configures waste rubber in a plate shape and laminates polystyrene foam on the rubber plate. The structure suggests that it is difficult to secure sufficient strength as a floor plate, and the polystyrene foam layer must be formed at a certain level or higher to obtain a desired interlayer sound insulation effect and shock absorption effect. There is a disadvantage that must be excessively large, and accordingly there is a limit that is not realistic as the construction cost is significantly increased.

The present invention is a sound insulation plate structure for preventing the interlayer noise of the multi-layer structure to laminate the lower plate, the middle plate and the upper plate so that the space is formed therein, the insertion plate is further laminated between the intermediate plate of the multilayer structure The insertion plate is formed of an air cap to reduce noise and vibration at the boundary and boundary surfaces of each layer, and to absorb shocks from the floor.

In addition, it is an object to further protect the inside by adding a protective plate on the outer side of the upper and lower plates, and to further waterproof by vinyl and silver foil further laminated.

The present invention is a sound insulation plate structure for preventing the interlayer noise of the multi-layer structure formed by stacking the lower plate and the intermediate plate, the upper plate, the air filling unit is filled between the lower plate and the intermediate plate and the intermediate plate and the upper plate at regular intervals It is characterized in that a plurality of plate-shaped air caps are inserted and stacked.

In addition, the lower plate, the middle plate and the upper plate is made of a corrugated plate structure or a plurality of through holes are formed.

In addition, the intermediate plate inserted between the upper plate and the lower plate is made of two or more layers, characterized in that the air cap is inserted between the intermediate plate.

In addition, the outer side of the upper plate and the lower plate is characterized in that the protective plate and the thin film layer is further laminated.

The present invention is effective in the sound-absorption, sound-absorbing and buffering effect by absorbing the noise and vibration of the air-filled portion formed in the laminated structure and the air cap to block each space formed inside.

In addition, it is configured to further laminate the vinyl or silver foil on the outer side of the upper and lower plates, to protect the interior of the soundproof panel, there is an effect that also provides a waterproof effect.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the sound insulation plate for preventing the inter-layer noise according to an embodiment of the present invention.

1 and 2 are a basic configuration diagram and a cross-sectional view of the sound insulation board according to an embodiment of the present invention.

1 and 2, the soundproof plate according to the present invention is the lower plate 20, the intermediate plate 30 and the upper plate 10 is laminated, the upper plate 10 and the intermediate plate and intermediate plate An air cap 40 is formed between the 30 and the lower plate 20, and the protective plate 50 and the thin film layer 60 for waterproofing are formed on the outer side of the upper plate 10 and the lower plate 20. It is.

The upper plate 10, the intermediate plate 30 and the lower plate 20 is made of a plate material, it can be composed of a rubber plate or synthetic resin plate or compressed styrofoam and can be selected according to the use environment.

In addition, the material of the upper plate 10, the lower plate 20 and the material of the intermediate plate 30 can be used differently.

The top plate 10, the bottom plate 20, and the intermediate plate 30 may be formed with a plurality of through holes 11, 21, and 31, as shown in FIGS. 1 and 2. As shown, it may be formed of a corrugated structure (15, 25, 35).

The upper plate 10, the lower plate 20 and the intermediate plate 30 has a thickness of about 3 ~ 10mm, the through hole formed in the upper plate 10, lower plate 20 and the intermediate plate 30 is At the interval of 3 ~ 5mm, make a diameter of 10 ~ 20mm. ,

The through holes 11, 21, and 31 may be formed in a circular or quadrangular shape. When noise or vibration flows into the through holes 11, 21, and 31, the through holes 11, 21, and 31 may be formed in the plurality of through holes 11, 21, and 31. By dispersing the noise or vibration, the noise or vibration is reduced.

In addition, the air cap 40 is inserted and stacked between the upper plate 10 and the intermediate plate 30, and the intermediate plate 30 and the lower plate 20, and flows into the through holes 11, 21, and 31. Thus, the air filled portion 41 formed in the air cap 40 absorbs the dispersed noise or vibration, thereby improving soundproofing, sound absorption, and cushioning effects.
