DETAILED DESCRIPTION

[0021] The utility model is further described in conjunction with the accompanying drawings and embodiments.

[0022] like Figures 1 to 5As shown, the single-opening soundproof fireproof door described in the utility model comprises a door frame 1, a door leaf 2, a door handle 3, and a fireproof sealing strip 4. The door leaf 2 is installed on the inner wall of one side of the door frame 1, and the door handle 3 is installed on the door leaf 2. The surfaces of the door leaf 2 and the door frame 1 that contact each other after closing are relatively complementary corrugated inclined surfaces, and the fireproof sealing strip 4 is arranged between the inclined surfaces of the door leaf 2 and the inclined surfaces of the door frame 1. The door leaf 2 comprises a first steel plate 21 arranged on the top surface and a second steel plate 22 arranged on the bottom surface, a cavity 23 is arranged between the first steel plate 21 and the second steel plate 22, and a sound insulation layer 24 is arranged on one side of the first steel plate 21 and the second steel plate 22 close to the cavity 23, and the first steel plate 21 and the second steel plate 22 are connected to the sound insulation layer 2 4, a transition layer 25 is provided between the first steel plate 21 and the second steel plate 22, and a concave structure 251 is provided on the surface where the first steel plate 21 and the second steel plate 22 are connected to the transition layer 25, and the material of the transition layer 25 is filled in the concave structure 251. By providing an uneven transition layer 25 in the middle between the first steel plate 21 and the second steel plate 22 and the sound insulation layer 24, the adhesion strength between the first steel plate 21, the second steel plate 22 and the sound insulation layer 24 is enhanced, the sound insulation layer 24 is prevented from falling off, and a good sound insulation effect is ensured; a reinforcing rib 26 is connected between the two layers of the sound insulation layer 24, and a sound-absorbing cotton 27 is attached to the outer wall of the reinforcing rib 26. The setting of the reinforcing rib 26 can improve the strength of the fire door on the one hand, and prevent the sound insulation layer 24 from falling off on the other hand, and ensure a good sound insulation effect.

[0023] The thickness of the sound insulation layer 24 is greater than that of the transition layer 25, and the reinforcing ribs 26 are corrugated, so that the sound absorption area of ​​the sound-absorbing cotton 27 can be increased and the sound insulation effect can be improved; the size and shape of the fireproof sealing strip 4 are adapted to the contact surface of the door leaf 2 and the door frame 1 after closing, which further improves the sealing performance;

[0024] In actual work, when the door leaf 2 is in a closed state, since the contact surfaces of the door leaf 2 and the door frame 1 after closing are relatively complementary corrugated slopes, the gap between the two is smaller, and in addition, a fireproof sealing strip 4 is provided between the slope of the door leaf 2 and the slope of the door frame 1, which makes the airtightness stronger, thereby greatly improving the sound insulation and fire resistance of the fire door; by providing a sound insulation layer 24, the sound insulation layer 24 is filled with rock wool or glass fiber, so as to improve the sound insulation of the fire door, and by providing a cavity 23, and reinforcing ribs 26 are connected between the two layers of the sound insulation layer 24, and sound-absorbing cotton 27 and sound insulation strips 11 are attached to the outer wall of the reinforcing ribs 26, such a setting further improves the sound insulation performance of the fire door.
