The invention discloses a sound insulation fireproof door which comprises a door frame, a door leaf, a rib core plate, corrugated plates and a heat insulation and sound absorption material. The door leaf is pivoted to the door frame, the rib core plate is arranged in the middle of the door leaf, the corrugated plates are arranged on the two sides of the rib core plate, and the door leaf is filledwith the heat insulation and sound absorption material; the strength of the door leaf is enhanced through the rib core plate, and the corrugated plates arranged on the two sides of the rib core plateplay a role in assisting in enhancing the door leaf; the two sides of the door leaf are separated through the rib core plate and the corrugated plates, so that the effect of thermal bridge cutoff is achieved, and heat transfer is prevented; the door leaf forms a solid gas-solid double structure through the corrugated plates on the two sides, the sound insulation effect of the door leaf is enhanced. And the fireproof and sound insulation effects are further supplemented through the heat insulation and sound absorption material arranged in the door leaf; and compared with a traditional door, thesound insulation effect can be improved to over 45 db.

    本发明公开了一种隔声防火门,包括门框、门扇、肋骨芯板、波纹板和隔热吸音材料。通过在门框上枢接一门扇,门扇中部设置有肋骨芯板,肋骨芯板两侧设置有呈波浪状的波纹板,门扇内填充有隔热吸音材料,通过肋骨芯板加强门扇的强度,而通过设置于肋骨芯板两侧的波纹板,一是辅助起到增强门扇的作用,二是通过肋骨芯板和波纹板对门扇两侧进行隔断,从而起到热桥断桥的作用,进而防止热量传递,三是通过两侧的波纹板,使门扇形成固体‑气体‑固体的双重结构,使得门扇的隔音效果得到增强,并通过设置于门扇内的隔热吸音材料进一步补足防火和隔音的效果,相对于传统的门具而言,可以使隔音效果提升至45db以上。
