Abstract

The invention provides a sound-and-fire proof door leaf structure. The sound-and-fire proof door leaf structure comprises a door frame and a door sheet, wherein the door sheet is connected to the door frame through a hinge; the door sheet is provided with a door lock; the door sheet comprises a first door sheet and a second door sheet; the first door sheet is connected to a first frame; the second door sheet is connected to a second door frame; a first keel is arranged on the tops of the first door frame and the second door frame; a second keel is arranged at the bottoms of the first frame and the second frame; the first frame is provided with a first sound-absorbing plate; the second frame is provided with a second sound-absorbing plate; a sealed cavity is formed between the first sound-absorbing plate and the second sound-absorbing plate; the sealed cavity is in a vacuum state; the sealed cavity is suspended on the first keel; the second keel is provided with an elastic support for connecting the sealed cavity. The sound-and-fire proof door leaf structure is characterized in that a sound-insulating material and a vacuum sealed cavity are arranged between the two layers of door sheets, so that transmission of sound is effectively blocked.

Description

technical field [0001] The invention belongs to the field of fire doors, in particular to a soundproof and fireproof door structure. Background technique [0002] Fire doors are common openable and closable fire separation components in various buildings. Fire doors that meet the requirements can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. The high temperature resistance and heat insulation performance of fire doors is mainly determined by the performance of the fireproof filler layer in the door body. According to the different functions and uses of houses, there are corresponding requirements for fire doors. For example, some high-end office places, conference rooms, lounges, etc. need a relatively quiet environment, so higher sound insulation requirements are put forward for fire doors. Existing High-quality fire doors cannot meet this requirement. Contents of the invention [0003] In view of this...
