The present invention relates to an interlayer floor impact sound absorbing material of a multi-family house installed in a wall or a floor structural material of a multi-family house, such as an alliance, a multi-family house, an apartment, and the like, in which a floor and a wall must be shared with a neighboring generation. The present invention relates to an interlayer floor impact sound absorbing material of a multi-family house that forms a floating floor structure for preventing shock vibration applied to the floor from being walked by a person, falling of an object, moving furniture, etc. to the lower floor.

In general, in buildings such as multi-family houses, townhouses, and schools, where walls and floors must be shared with neighboring households, such as walking in the room, children jumping, falling objects, and other furniture, etc. Dust-proofing, sound-proofing materials, and heat insulators are used, respectively, to exhibit the effect of absorbing the floor impact sound generated by the impact applied to the floor or the noise of the room transmitted to the neighboring generation through the wall and blocking the sound.

One example of such building materials is as follows.

Glass insulation, urethane foam board, foamed polystyrene foam (Styrofoam), rock wool, foamed polyethylene insulation, and carbonized cork board are mainly used as thermal insulation materials for sound absorption and thermal insulation of buildings.

The above products are somewhat different depending on the density, but in general, only a product having a thickness of 30mm-50mm can exhibit a certain degree of insulation effect. In particular, as the sound absorbing material, foamed polystyrene foam (Styrofoam) and foamed polyethylene foam (PE Foam) are used in addition to the natural wood fibers and polyester fibers. There is a disadvantage that can not expect a complete sound insulation effect as it passes through as it is not absorbed.

In addition, conventionally, a light-weight foamed concrete layer or a foamed polystyrene foam layer is provided as a buffer layer on the floor concrete slab for the purpose of thermal insulation and to reduce the inter-floor impact sound of an apartment house or a high-rise building. have. This is because apartment buildings are mostly constructed in the same way as above, but the reality is that vibrations caused by falling objects or jumping impacts of children are transmitted to the lower floors as they are, resulting in noise.

Recently, in order to increase the effect of interlayer floor impact sound, special vibration isolators such as anti-vibration rubber pads having a thickness of 10 mm to 50 mm are used to block the vibration caused by the impact applied from the upper layer. .

1A and 1B are cross-sectional views of the structure of the bottom layer and the bottom layer using the anti-vibration rubber pads. Here, Figure 1a is a cross-sectional view of a general floor structure material, Figure 1b shows a floor structure material with a built-in anti-vibration rubber pad.

In FIG. 1B, unlike the conventional floor structure of FIG. 1A, a vibration damping rubber pad having a thickness of about 10 mm to 50 mm is installed below the lightweight foam concrete layer to absorb the shock applied from the upper layer by the elasticity of the rubber pad and to be transmitted to the lower layer. It has been shown to play a role in reducing.

However, because the concrete slab layer, anti-vibration rubber pad layer, lightweight foam concrete layer, and floor plastering mortar layer are bonded together, the anti-vibration effect on the impact can be halved, and it is essentially floated to reduce the floor impact sound. Flooring (floating floor) structure or the hypothesis of the auxiliary ceiling can be said to be the most effective, in this case, the floor height is low, there is a problem that the construction cost is high.

On the other hand, Patent No. 0495041 registered by the applicant of the present invention is molded by extruding the copolymer (PP, PE Copolymer) raw material of polypropylene and polyethylene, and the sound absorbing on both sides of the plastic double board with an air layer in the middle The interlayer noise absorbing material formed by attaching the polyester fiber sheet with excellent insulation effect is embedded in the floor structure of the new building, so that the vibration is absorbed by the shock and the sound insulation by sound absorption and sound insulation And has suggested a structure that maximizes the insulation performance by the air layer.

However, while the above structure exhibits excellent effects in soundproofing, dustproofing, and heat insulation, there is a concern that the impact sound generated in the upper layer through the connection joint grip is transmitted to the lower slab through the connection joint grip of the plastic injection molding. This may act as a cause of reducing the interlayer noise preventing performance of the structure.

Therefore, the present invention has been proposed to solve the above problems, the sound-absorbing and excellent heat-insulating performance (synthetic fiber board) on the top and bottom of the plastic double board as a central substrate riveting of elastic rubber material By installing a thin plate partially bonded through the member into the floor structure when constructing a building, it is equipped with a floating floor structure that can maximize the anti-vibration effect as the vibration absorption due to the shock vibration of the floor layer, and the sound insulation and insulation performance by sound absorption and sound insulation. The purpose is to provide a shock absorbing material between the floors of the MDU.

In addition, the present invention forms a primary floating bottom structure between the slab layer and the lightweight foam concrete layer through the thin plate attached to the sound-absorbing fiber board on the plastic double board as a central substrate having an air layer formed therebetween, By contacting the convex head part of the made rivets with the slab layer, the sound absorbing fiber board and the slab layer are separated, thereby forming a secondary floating floor structure, thereby minimizing the transmission of impact sound applied to the floor of the apartment house to the concrete slab layer. Another object is to provide a shock absorbing material between floors of an MDU that forms a floating floor structure.

In addition, the present invention by providing the insulation effect through the air layer between the sound absorbing board and the slab layer through the air layer and the rivet head portion of the board member as the center substrate in addition to the dustproof, soundproof effect, the manufacturing cost is much higher than the existing dustproof, soundproofing, insulation Another object of the present invention is to provide a shock absorbing material between floors of a multi-family house that forms a floating-floor structure that is less expensive and saves energy due to an insulation effect.

In addition, the present invention has another object to provide an interlayer floor impact sound absorbing material of a multi-family house that forms a floating floor structure that can be used as an interior finishing material, such as machine room, air conditioning room, performance hall, gymnasium.

In order to achieve the above object, in the present invention, the high-density plastic resin raw material is manufactured by extrusion molding, the center board member having a first air layer in the middle portion to block the impact sound flowing from the upper layer and at the same time have a heat insulating function; It is bound to the upper and lower surfaces of the center board member, the synthetic fiber board that absorbs and extinguishes the first impact sound flowing from the upper layer; Bonding means which firmly bonds between the center board member and the synthetic fiber board, and partially protrudes from the lower synthetic fiber board to a predetermined height so as to space between the lower synthetic fiber board and the slab layer to form a second air layer. Including,

An interfloor floor of a multi-family house, wherein the floor plaster mortar layer and the slab layer are separated by the first air layer of the center board member and the second air layer of the binding means to form a floating floor structure in which the floor is floating in the air. Provides a shock absorber.

Here, the first embodiment of the board member, the upper and lower plates are installed with a predetermined vertical height interval; And partition plates arranged in a straight line at a predetermined interval between the upper and lower plates.
