SOUND-PROOF DOOR
To suppress looseness and rattling of an iron core assembled inside a flush structure sound-proof door.SOLUTION: A flush structure sound-proof door includes an outer frame F having a predetermined thickness T, an inner vertical frame 6 on one side and an inner vertical frame 7 on the other side, each of which has the predetermined thickness T and has an iron core 8 fitted thereto, an outer sound insulation plate 28 having the predetermined thickness T and abutting against the vertical frame 16 on one side of the outer frame F and the inner vertical frame 6 on one side, an outer sound insulation plate 29 having the predetermined thickness T and abutting against the vertical frame 17 on the other side of the outer frame F and the inner vertical frame 7 on the other side, an inner sound insulation plate 25 abutting against the inner vertical frame 6 on one side and the inner vertical frame 7 on the other side on one surface side of the outer frame F, a plurality of horizontal crosspieces 4 and a plurality of sound absorbing materials abutting against the inner vertical frame 6 on one side and the inner vertical frame 7 on the other side on the other surface side of the outer frame F, and a first surface material 41 and a second surface material 42 provided on one surface side and the other surface side of the outer frame F. The sum of the thickness of the inner sound insulation plate 25 and the thickness of each horizontal crosspiece 4 is the predetermined thickness T.SELECTED DRAWING: Figure 8
【課題】フラッシュ構造の防音ドアの内部に組まれた鉄芯の緩みやがたつきを抑制する。【解決手段】所定の厚さＴを有する外枠Ｆと、鉄芯８がそれぞれ嵌め込まれた所定の厚さＴを有する一方側の内部縦枠６及び他方側の内部縦枠７と、外枠Ｆの一方側の縦枠１６、及び一方側の内部縦枠６に当接する所定の厚さＴを有する外側遮音板材２８と、外枠Ｆの他方側の縦枠１７、及び他方側の内部縦枠７に当接する所定の厚さＴを有する外側遮音板材２９と、外枠Ｆの一方の表面側で一方側の内部縦枠６及び他方側の内部縦枠７に当接する内側遮音板材２５と、外枠Ｆの他方の表面側で一方側の内部縦枠６及び他方側の内部縦枠７に当接する複数の横桟４及び複数の吸音材と、外枠Ｆの一方の表面側及び他方の表面側に設けられた第１面材４１及び第２面材４２とを備え、内側遮音板材２５の厚さと各横桟４の厚さとの和は、所定の厚さＴである。【選択図】図８
