The present invention relates to a sound insulation board structure having a structure that can reduce the noise between floors in a multi-story building such as an apartment or an office.

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 reason for the noise between floors is that children are playing or scratching while moving things. Vibration and noise are two main reasons.

Such vibrations and noises can be reduced by increasing the floor height, and it is known that the structure of finishing the soundproof plate on the slab can be more effectively reduced.

Background Art [0002] A bottom plate for reducing interlayer noise and vibration is generally 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 noise by blocking noise and vibration generated by various factors from being excited at the resonance frequency of the structure and increasing the transmission loss by reducing the influence of air coupling.

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. For example, the Republic of Korea Utility Model Registration No. 0293443 perforates the air holes of the small holes in the upper plate and the lower plate, and drilled through the larger air holes in the middle plate material and laminated them, so that each ventilation hole is irregularly replaced with soundproofed moistureproof The board is presented.

However, the laminated structure of the double structure or the hollow plate as described above is a hard-board structure, and the noise and vibration reduction due to the impact is not effectively made as it is transmitted as it is, as a complement to the bottom plate Although the bottom layer structure was improved by forming a foam concrete layer before finishing, the overall soundproof and soundproof performance was achieved, but there was a disadvantage that the shock absorption of the soundproof panel itself was not high.

As another attempt to improve the shock absorbing properties of the soundproof plate material, a soundproof plate having a composite plate structure using rubber or waste rubber has been proposed, and Korean Patent Laid-Open Publication No. 1998-084997 consists of waste rubber in a plate shape and a polystyrene foam on the rubber plate. Laminated structure suggests that it is difficult to secure sufficient strength as a bottom plate, and the polystyrene foam layer must be formed to 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 was a limit that is not realistic as the construction cost is significantly increased.

According to the present invention, in presenting a soundproof plate having a structure in which a plate is laminated to form a space therein, each layer is newly formed by presenting a soundproof plate structure in which a space is formed in each plate and a laminate is placed between each space. The purpose of the present invention is to obtain a subtraction effect of noise and vibration at the boundary surface and the boundary surface of the space, and to effectively absorb the impact from the floor.

To this end, the present invention forms a sound absorbing groove arranged in a checkerboard structure on the lower plate and the upper plate, respectively, and the middle plate is formed of a through hole to be paired with the sound absorbing groove, the sound absorbing groove and the middle of the upper and lower plates when stacked The through-holes of the plate are configured to be paired with each other, and the soundproof plate structure for preventing the interlayer noise of putting the foil between the upper plate and the middle plate and the middle plate and the lower plate is laminated integrally with the foil. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is for illustrating the basic configuration of the present invention, the present invention is between the lower plate 10, the upper plate 20 and the intermediate plate 30, intermediate plate 30 and the upper and lower plate inserted in the middle It consists of a foil 40 is inserted and molded integrally compressed.

The lower plate 10 and the upper plate 20 is made of a rubber plate, a wooden plate or a synthetic resin plate having a thickness of approximately 4 ~ 10mm, the plate has a circular or saga of 10 ~ 20mm size formed at intervals of about 3 ~ 5mm Sound absorbing grooves 11 and 21 are formed.

In addition, the sound absorbing grooves 11 and 21 are formed to have a depth of about 2 ~ 7mm to have a bottom thickness of about 3mm or more.

The sound absorbing grooves formed in the upper and lower plates may be formed directly on the plate, and may be formed in a structure in which the plate having the through holes and the plate attached thereto are integrally attached and formed.

The sound absorbing groove blocks noise and vibration from being excited at the resonant frequency of the structure and increases the transmission loss by reducing the influence of air coupling to exert the noise and vibration reduction effect.

The intermediate plate 30 is stacked to be positioned between the lower plate and the upper plate, and absorbs the shock by the buffering action and reduces the propagation of noise and vibration by the foreign material. Accordingly, the intermediate plate is a foam used as a compression sheet formed with a rubber plate or a through hole of an elastic material.

The intermediate plate is formed with a through-hole 31 corresponding to the sound absorbing groove formed in the upper and lower plates, the through-hole is divided by the space portion inside the soundproof plate by a foil to be described later to block the propagation of noise and vibration and to absorb sound pressure It acts to effectively reduce noise and vibration.

The foil 40 is for absorbing sound pressure to effectively reduce noise and vibration, and a thin vinyl film or Hanji is used. The foil is located between the lower plate and the middle plate and the middle plate and the upper plate, and when noise and vibration flow into the sound absorbing groove and the through hole, the sound pressure is absorbed by the vibration (vibration) by the thin film, thereby forming an interface in the space part. It reduces the effect of air bonding and increases the transmission loss due to the change of the medium caused by the foreign material, thereby reducing noise and vibration.

3 illustrates a structure in which the lower plate-paper-intermediate plate-paper-top plate is integrally stacked as an example in which the soundproof plate is configured by the above configuration.

In the above, the upper plate and the lower plate may be composed of various materials such as rubber plate, wood plate or synthetic resin plate, the intermediate plate is composed of rubber plate or compressed styrofoam to improve the shock absorption effect.

Thus, by configuring the upper and lower plates, the intermediate plate and the foil with different materials, the effect of reducing noise and vibration at the boundary of each medium is improved.

The rubber plate is advantageous in that the resources can be recycled by forming a compressed material of the waste tire powder in which the waste tire is pulverized.

In addition, by mixing the waste tire powder and sawdust in a ratio of 6 to 8: 4 to 2 and by applying an adhesive, forming the upper plate and the lower plate can improve the strength of the soundproof plate.

FIG. 4 illustrates a structure in which the middle plate is formed in two layers between the lower plate and the upper plate, and a foil is formed on the boundary surface of each plate in the structure of the soundproof plate.

The structure has the effect of improving the noise and vibration reduction effect, and the impact absorption performance by forming one more intermediate plate layer.

5 is a view showing the construction of the soundproof plate according to the present invention by laying the soundproof plate according to the present invention on the concrete floor 100 constituting the floor of the building and applying the foam concrete 110 thereon, the final finishing material 120 By including the various noises and vibrations applied from the floor can be reduced.

The present invention can improve the noise and vibration subtraction effect by the laminated structure formed space therein and the foil blocking each space, the upper and lower layers, the middle layer and the foil is composed of heterogeneous materials, noise and vibration at each boundary surface There is an effect that the deduction effect of the, and by recycling the waste tire powdered by the method of mixing the sawdust with the sawdust can obtain the recycling effect of resources.
