Problems solved by technology

[0002] At present, most of the fire doors used in land building residences and ship cabins are filled with heat insulating materials between the inner and outer metal panels, and then an additional steel plate wrapping structure is used at the edge of the door leaf to cover the gap between the door leaf panels to achieve better protection. Fireproof effect, this traditional door leaf wrapping structure is simple and rough, not only wastes steel plate materials, but also needs to make special molds for processing, the manufacturing process is complicated, and the installation is cumbersome. Deformation or falling off due to frequent collisions, which affects the appearance and performance of fire doors and shortens their service life

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0021] Such as figure 1 As shown, the high sound insulation fireproof door of the present invention includes a door frame 1 and a door leaf 2, one side of the door leaf 2 is hinged to the door frame 1 through several hinges 8, and a door lock 4 is provided on the other side. Such as figure 2 and Figure 4 As shown, the door leaf 2 further includes: an outer panel 21 , an inner panel 22 , two perforated sound-absorbing panels 28 sandwiched in the interlayer between the outer panel 21 and the inner panel 22 , and a heat-insulating and sound-insulating core material 23 . The heat and sound insulation core material 23 is filled between each punched sound-absorbing panel 28 and its adjacent outer panel 21 or inner panel 22 and is combined with the outer panel 21 or inner panel 22 with an adhesive. An air cavity 29 is formed between the perf...

Abstract

The invention provides a high-sound-insulation fireproof door. The high-sound-insulation fireproof door comprises a door frame (1) and a door leaf (2), wherein one side of the door leaf is hinged to the door frame (1). The door leaf (2) further comprises an outer panel (21) and an inner panel (22). Two punching acoustical boards (28) are further arranged between the outer panel (21) and the inner panel (22). Heat insulating and sound insulating core materials (23) are filled into an interlayer between each punching acoustical board (28) and the outer panel (21) or the inner panel (22). An air-filled cavity (29) is formed between the two punching acoustical boards (28). Due to the fact that the air-filled cavity composed of the two punching acoustical boards is formed in the door leaf of the high-sound-insulation fireproof door, the sound insulating effect is good, the heat preserving, airtight and fireproof functions are further possessed, an edge covering structure does not need to be arranged, the structure and the process are simple, and the appearance is attractive and high-grade.

Description
