Benefits of technology
[0009]Accordingly, it is an object of the present invention to provide a soundproof panel for an impact sound insulation which is able to resolve an inter-floor noise by providing a soundproof panel for an impact sound insulation which has an excellent impact sound absorption performance.
[0012]The hexagonal soundproof material 29 is preferably waste iron or waste aluminum which has low manufacture cost and has excellent inflammable property and anti-abrasion property and reliable strength.
Problems solved by technology
So, disputes may occur between neighbors due to noises.
In particular, among noises, vibration noises transferred from an upper stair to a down stair are most serious problems which disturb a neighbor's sleeping and personal life.
However, there is not disclosed a method for obtaining a soundproof effect by changing a structure of a floor material.

Embodiment Construction
[0018]The preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0019]Expanded vermiculite, which is an important element of a lower panel, consists of chemical components of CMg, Fe3+, Al3(Al, Si)4O10(OH)2·4H2O. It is a kind of clay formed of aluminum, magnesium, silicate hydroxide of iron. The hardness of expanded vermiculite is 1˜2, and viscosity is 2.76. It is split across in a flat shape. The color of expanded vermiculite is light gray or brown and is lustrous like pearl. In addition, the expanded vermiculite well dissolves in acid solution and has strong positive ion exchange ability. Being heated, it well expands. The expanded vermiculite has numerous porous thus having good absorption ability, so that it is used as an anti-heat material and soundproof material.

Abstract
A soundproof panel for an impact sound insulation is disclosed, which is able to resolve an inter-floor noise by providing a soundproof panel for an impact sound insulation which has an excellent impact sound absorption performance. The soundproof panel for an impact sound insulation comprises a lower panel which is made of a porous material; a hexagonal soundproof material which is adhered to an upper surface of the lower panel, with hexagonal holes having different sizes passing through the hexagonal soundproof material; and an upper panel which is adhered to an upper surface of the hexagonal soundproof material and is made of an expandable polymer material.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a combined material designed to prevent a propagation of floor impact sound generating between floors of a building, and in particular to a soundproof panel for an impact sound insulation which is able to prevent noises generating between floors of a building (apartment or public housing complex) formed of multiple floors.[0003]2. Description of the Background Art[0004]As city population increases, a public housing complex such as a multiple family housing complex or apartments increases as compared to a single-family type house. In such a public housing complex, multiple families live with a wall boundary being provided between the neighboring houses. So, disputes may occur between neighbors due to noises.[0005]In particular, among noises, vibration noises transferred from an upper stair to a down stair are most serious problems which disturb a neighbor's sleeping and personal life.[000...
