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 noise can be reduced by increasing the height of the bottom layer, 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 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 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 is a sound insulation of the structure so that each ventilation hole is replaced irregularly by drilling a hole of the small hole in the upper plate and the lower plate, and drilled through a larger ventilation hole in the middle plate and laminated them. Moisture proof 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.

In another attempt to improve the shock absorption of the soundproof plate material, a soundproof plate of a composite plate structure using rubber or waste rubber is proposed, and Korean Patent Laid-Open Publication No. 1998-084997 configures waste rubber into a board and polystyrene foam on the rubber plate. Laminated structure is proposed, such a structure is difficult to secure sufficient strength as a base plate, and the polystyrene foam layer must be formed at a certain height to obtain the desired interlayer sound insulation effect and shock absorption effect to meet this interlayer There is a disadvantage that the height must be too large, and accordingly the construction cost is significantly increased, there was a limit that is not realistic.

The present invention provides a soundproof plate of a laminated structure of a plate material so that a space is formed inside, so that the plate formed in the intermediate layer made of corrugated cardboard of rubber material to obtain the effect of subtracting noise and vibration by the valley formed in the intermediate layer. And it aims to be able to effectively absorb the impact applied from the bottom.

To this end, the present invention in the soundproof plate structure for preventing the interlayer noise of the structure in which the upper plate and the lower plate is attached to the upper and lower portions of the intermediate plate of the structure in which the space is formed inside, the intermediate plate is made of an uneven type as a rubber material It proposes a sound insulation plate for preventing the interlayer noise of the structure in which the upper plate and the lower plate is integrally attached to the upper and lower portions.

In addition, the present invention provides a structure in which the concave-convex intermediate plate is laminated so that the valleys are orthogonal to each other.

In addition, the present invention proposes a structure that improves the sound-absorbing effect by forming a stick between the intermediate plate in the structure in which the intermediate plate is laminated.

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

1 is for illustrating the basic configuration of the present invention, the present invention is composed of a lower plate 10, the upper plate 20 and the concave-convex intermediate plate 30 inserted in the middle.

The lower plate 10 and the upper plate 20 is made of a rubber plate, a wooden plate or a synthetic resin plate or compressed styrofoam having a thickness of approximately 2 ~ 10mm.

The uneven type intermediate plate 30 may be formed by bending a rubber plate having a thickness of about 2 to 5 mm into an uneven shape or bending it into a wave shape to force-bond the upper plate and the lower plate to upper and lower surfaces. In the step can be carried out with a structure in which the intermediate plate is formed in a corrugated plate structure of irregular or wavy.

The intermediate plate of the corrugated structure provides an advantage that the manufacturing and lamination of the unit board is very easy while easily securing the necessary sound absorbing space layer compared to the conventional sound absorbing groove structure or honeycomb shock absorber.

1 illustrates an embodiment in which an intermediate plate is formed in an uneven shape, and FIG. 2 illustrates an embodiment in which a middle plate is formed in a wave shape. The intermediate plate may be configured by recycling waste tires for recycling general rubber or resources.

The intermediate plate may be composed of a single layer, and may be formed of the double layer in order to improve sound insulation, sound absorption, and buffering effect. To form an attachment.

Figure 3 shows an embodiment in which the intermediate plate is a multi-layer structure, by this structure each intermediate plate is formed integrally attached to each other forming a lattice point has the effect of improving the shock absorbing ability.

4 illustrates an embodiment of a structure in which the foil 40 is coupled between the intermediate plate without directly attaching the intermediate plate and the intermediate plate.

The foil is a thin vinyl film or thin plastic sheet or cloth or paper with high nodule strength. Such a structure can effectively reduce noise and vibration by isolating the bone formed in the intermediate plate to absorb sound pressure.

In other words, the foil placed between the middle plate and the middle plate absorbs the sound pressure by vibration (vibration) by the thin film when noise and vibration are introduced, and reduces the influence of air bonding by forming the interface in the space and the medium by the foreign material By increasing the transmission loss caused by the change of, it reduces the noise and vibration.

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 a rubber plate 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.

In the case of using a rubber plate in the above, there is an advantage that the resources can be recycled by configuring the waste tire powder, which has been pulverized into the waste tires, by molding and pressing.

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.

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 applying the A to 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, and the upper and lower layers, the middle layer and the foil are composed of heterogeneous materials, respectively, to prevent noise and vibration at each interface. There is an effect that the deduction effect is achieved, and the recycling of resources can be obtained by forming a plate by mixing waste tire with powder of sawdust.
