Description

Vibration-resistant soundproofing material

[0001] The present invention relates to an active controllable vibration-insulating soundproofing material for slabs such as floors and ceilings of apartment buildings, and is intended to reduce inter-floor noise used in the floors of multi-story buildings and the floor structures of apartment buildings.

[0002] Modern urban architecture is often formed as a multi-layered structure that divides multiple spaces vertically to maximize land utilization. However, the walls and slabs that divide multiple spaces require basic requirements to allow each space to maintain an independent environment.

[0003] Among these basic requirements, the most important is to prevent the temperature and noise generated within a space from being transmitted to neighboring spaces through walls or slabs.

[0004] In particular, in the case of slabs, hot water pipes are laid to transmit temperature to the target space due to the characteristics of residential spaces in our country, and the frequency of noise generation, such as floor impact noise, is high compared to other structures such as walls.

[0005] Therefore, when constructing a multi-story building, special efforts are required to reduce heat loss and inter-floor noise in the slab. To this end, a soundproofing layer of a certain thickness is formed on top of the already formed slab, and after installing hot water pipes, the soundproofing layer and the upper part of the hot water pipes are again laid with finishing mortar.

[0006] Recently, multi-family housing such as apartments and villas have been built in multiple floors and housed in multiple generations. However, these multi-family buildings generate noise between upper and lower floors, which has raised many problems, and the problem is becoming increasingly serious in modern society.

[0007] Korean Patent Publication No. 2005-0094625 relates to an inter-floor noise prevention agent (hereinafter referred to as an inter-floor noise prevention agent) having a performance structure for reducing noise and impact noise generated between floors of a building formed of concrete and concrete structures, such as an apartment or multi-family house, and a mold and molding thereof. The invention discloses an inter-floor noise prevention agent, a mold and molding thereof, which is buried between slabs and lightweight foam concrete layers between floors of a building and absorbs, disperses, attenuates, and extinguishes impact (noise) energy applied to the floor surface of the upper floor, thereby preventing noise and vibration caused by impact and contributing to a comfortable living environment.

[0008] In addition, Korean Patent Publication No. 10-1803777 relates to a plywood panel and a soundproofing material using the same, and more specifically, discloses a plywood impregnation liquid containing polystyrene resin, which impregnates and coats the inside of the plywood, thereby improving structural durability while compensating for the disadvantages of paper plywood that is vulnerable to moisture, and maintaining a uniform thickness of the outer coating layer to achieve high strength, a plywood panel impregnated therewith, a method for manufacturing the same, and a soundproofing material using the same.

[0009] In addition, Korean Patent Publication No. 1998-0023716 relates to a method for manufacturing a plate-shaped polyurethane foam sound-absorbing material having a rough surface and the sound-absorbing material, and more specifically, discloses a method for manufacturing a plate-shaped polyurethane foam sound-absorbing material having a rough surface, characterized in that the plate-shaped polyurethane foam sound-absorbing material is formed into a plate shape so as to have a rough surface in which grooves and protrusions are continuously formed on one side before and after foaming of polyurethane into a foam.

[0010] Korean Patent Publication No. 10-1274414 relates to a method for manufacturing an interlayer sound-insulating material using a crosslinked waste foam made of a synthetic resin, and comprises a heating and pressing step of putting crushed or cut crosslinked waste foam into a mold and pressing it with a mold while heating it with hot air to form a first molded body, a cutting step of cutting the first molded body of the heating and pressing step into a plurality of plates to form a second molded body, and a final forming step of forming a plurality of sound passages that are parallel or alternate with each other on one side of the second molded body of the cutting step, and in the heating and pressing step, hot air of 115°C to 200°C is blown into the crosslinked waste foam inside the mold while pressing the crosslinked waste foam inside the mold to 40% to 80% by volume, and in the final forming step, the second molded body is heated with a heating roll or a heating mold for 10 to 20 seconds. A method for manufacturing an interlayer soundproofing material characterized by forming a sound passage by applying pressure is disclosed.

[0011] However, the prior art discloses a technology for manufacturing by adding separate additional equipment, materials, etc. to prevent inter-floor noise, and thus, a technology for reducing inter-floor noise through secondary molding utilizing existing materials without adding additional equipment or materials, as in the present invention, has not been disclosed.
