Problems solved by technology

[0002] Fire door refers to the door body that can meet the fire resistance stability, integrity and heat insulation within a certain period of time. The gaps between fire or smoke are usually provided with expansion fireproof sealing strips. The current type of sealing strips for fire doors is single, which only expands to seal when a fire occurs. In most of the daily time (that is, no fire danger) time) has no other effect
Moreover, the embedded strip-shaped sealing strip is slow in the process of expanding and sealing the gap, and cannot block the flames and poisonous smoke in time

Embodiment Construction

[0029] The scheme of this application is further described in conjunction with the accompanying drawings as follows:

[0030] See attached Figure 1-7 , a fireproof door, comprising a door leaf 1 and a door frame 2, one side of the door frame 2 is connected to a wall, and the other side is provided with a groove 20 corresponding to the periphery of the door leaf 1.

[0031] Two first fireproof sealing strips 3 are embedded on the side where the door frame 2 is connected to the wall. The first fireproof sealing strip 3 is flat and integrally formed of expanded graphite material. There is an installation gap between the door frame 2 and the wall due to the installation process or the size of the wall, which is generally 2-20mm. The first fireproof sealing strip 3 can expand by more than 20 times when heated, and can effectively fill the installation gap , to prevent the installation gap through the fire and the entry of poisonous smoke.

[0032] The groove 20 is embedded with...

Abstract

The invention provides a fireproof door, comprising a door leaf and a door frame, one side of the door frame is connected with a wall, a groove corresponding to the periphery of the door leaf is formed in the other side of the door frame, and a first fireproof sealing strip is embedded in the face, connected with the wall, of the door frame; a second fireproof sealing strip and a third fireproof sealing strip are embedded in the groove; the first fireproof sealing strip is in a flat strip shape; the second fireproof sealing strip comprises a strip-shaped main body, one side of the main body horizontally extends to form a wide edge, one side, away from the main body, of the wide edge is obliquely bent to form an elastic folded edge, the main body of the second fireproof sealing strip on thedoor frame is embedded in the groove wall of the groove, the wide edge is attached to the surface of the door frame, and the elastic folded edge abuts against the door leaf. According to the fireproof door, through cooperation of the fireproof sealing strips of multiple structures, an installation gap can be blocked in time when a fire disaster occurs, fire penetration and poisonous smoke invasion of the installation gap are prevented, the anti-collision effect can be achieved, and the applicability of the fireproof door is improved.

Description

technical field [0001] The invention relates to a fire door. Background technique [0002] Fire door refers to the door body that can meet the fire resistance stability, integrity and heat insulation within a certain period of time. The gaps between fire or smoke are usually provided with expansion fireproof sealing strips. The current type of sealing strips for fire doors is single, which only expands to seal when a fire occurs. In most of the daily time (that is, no fire danger) time) has no other effect. And the embedded strip-shaped sealing strip is slow in the process of expanding and sealing the gap, and cannot block flames and poisonous smoke in time. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a fireproof door, through the cooperation of fireproof sealing strips of various structures, the installation gap can be blocked in time when a fire occurs, preventing the installation gap from being penetrated by ...
