材１２を取付けて製造される。前記表面材１２は、高い
遮音性能を得るうえで、曲げ剛性が小さく面密度の高い
金属板１３、たとえば鉛板、鋼板等を使用し、その表面
に突板合板等の化粧板を貼着してなる。Conventionally, soundproof doors have been used in audio rooms, musical instrument practice rooms, and the like. As shown in FIG. 2, such a soundproof door is manufactured by filling a void portion 11 in the door frame 10 with a sound insulating material such as glass wool or a honeycomb core, and attaching surface materials 12 to both surfaces of the door frame. In order to obtain high sound insulation performance, the surface material 12 uses a metal plate 13 having a small bending rigidity and a high surface density, such as a lead plate or a steel plate, and a decorative plate such as a veneer plywood is attached to the surface thereof. Become.
しかしながら、かかる従来の防音ドアにおいては、製造
時または施工時のドアの寸法調整にドアの４周を切断す

FIG. 1 is a sectional view of a soundproof door according to this embodiment, in which a door frame 1 has notched step portions 1a and 1a on both inner surface sides thereof. The side edges of the metal plates 2 attached to both sides of the door frame 1 are locked to the step 1a. Further, a decorative plate 3 such as a decorative plywood attached to the outer surface of the metal plate 2 is fixed so that its side edges conceal both sides of the door frame 1.
金属板２，２とドア枠１とによって形成される空間内に
は遮音材としてグラスウール４と紙製のハニカムコア５
とが交互に充填される。In the space formed by the metal plates 2 and 2 and the door frame 1, glass wool 4 as a sound insulating material and a honeycomb core 5 made of paper.
And are filled alternately.
