In addition, the sound insulation sheet 30 is sandwiched between the two layers of the core material 20.

(4) Fourth Embodiment: Center and Both Sides Sound Insulation Sheet The sound insulation panel 4 of the fourth embodiment shown in FIG. 4 is in a state where the core material 20 having non-combustible heat insulation properties is between two metal plates 10. In addition to being sandwiched, the sound insulating sheet 30 is sandwiched between the metal plate 10 and the core member 20 on both sides and between the two layers of the core member 20.

  The sound insulation panels 1 to 4 of each of the above embodiments have an overall thickness of about 30 to 250 mm, the metal plate 10 has a thickness of about 0.2 to 2.0 mm, and the sound insulation sheet 30 has a thickness of 0.5 to 5. It is about 0 mm.

  As the metal plate 10, a color steel plate, a fluorine steel plate, a vinyl chloride steel plate, a stainless steel plate such as SUS, or the like is used. The core material 20 is made of a panel-like material made of inorganic fibers having nonflammability and heat insulation properties. For example, lime or the like is mixed with glassy iron furnace slag obtained by an iron making process and melted at a high temperature. Inorganic artificial fibers such as panel-like rock wool or panel-like glass wool are preferably used. As the sound insulating sheet 30, a sheet having sound insulating properties obtained by processing vinyl chloride, non-vulcanized rubber or the like into a sheet shape is preferably used.

  The sound insulation panels 1 to 4 have a basic manufacturing method of manufacturing a metal sandwich panel by bonding the two-layer core material 20 with an adhesive and then bonding the metal plate 10 to both surfaces of the two-layer core material 20. Is applied and the sound insulating sheet 30 is bonded to a necessary place.

  For example, in order to manufacture the sound insulation panel 1 of the first embodiment, the two-layer core material 20 is bonded with an adhesive, and then the sound insulation sheet 30 is bonded to the surface of the one core material 20 and then the metal is formed on both sides. The plate 10 is bonded. In order to manufacture the sound insulation panel 4 of the fourth embodiment, after the sound insulation sheet 30 is bonded to one surface of the single core material 20, the other core material 20 is adhered to the sound insulation sheet 30, and then both After the sound insulation sheets 30 are bonded to the surface of the core member 20, the metal plate 10 is bonded to the sound insulation sheets 30.

  The sound insulation panels 1 to 4 of the above embodiments can be suitably used as a wall material having sound insulation properties. For example, the walls of expressways and general roads where noise reduction is required in the surrounding environment, wall materials for rooms such as karaoke boxes and music studios when building rooms that are difficult to leak sound, and wall materials for clean rooms where noise reduction is required Used for etc. When using as a sound insulation panel, what the sound insulation sheet 30 is arrange | positioned only at one side like 1st Embodiment is constructed so that the sound insulation sheet 30 side may be distribute | arranged to the side which a sound source generate | occur | produces.

  According to the sound insulation panels 1 to 4 of each of the above embodiments, damage such as cracks due to shrinkage / expansion due to heat or adhesion of a snow melting agent is suppressed as in a conventional concrete panel, and high durability is exhibited. . Moreover, since it is comparatively lightweight, there is also an advantage that the workability is improved and the burden on the installer is reduced. Moreover, since it has not only sound insulation but also non-combustible heat insulation, it can be applied to places where such performance is required.
