The present invention refers to incombustible, adiabatic effects and excellent in noise is obtained a soundproof that allows manufacturing method thereof bent by a rope. is provided.
I.e., the present invention refers to sound door (1) constituting fore-aft door panel (3, 4) and, said door panel (3, 4) is fixed longitudinally welded quadrant on an engagement groove (5a) and coupling piece (6a) in response by using the mutual-fit arrangement with the is integrally combined with a section of the reinforcing rib different from (5, 6) and a, said door panel (3, 4) from the arc gas to the interphase the enclosed area of the (7) and reinforcement rib (5, 6) from the arc gas to the interphase the enclosed area of the (8) cap opener and the charge material in an area (2) and a, said sound door (1) is pivot hinge (9) in ceiling by a rack to be integrally moved with an acoustically isolating door (10) the re-with brilliant manufacturing packing (11) is attached, in parallel bar characterized by,
In the present invention provides an acoustically isolating door (1) the existing cap opener compared unstable multilayer constructions for acoustically insulating a source (2) and flame-retardant packing (11) is integrally III-V compound semiconductors when a fire breaks out in using and not which protect, by adiabatic effects and/or ice in order to save energy, is in preventing noise the recording operation. given. |
