Edge sealing structure of high-protection-performance fireproof door

Abstract

The invention discloses an edge sealing structure of a high-protection-performance fireproof door, and relates to the technical field of fireproof doors. The edge sealing structure comprises a door frame and a door plate. A strip-shaped groove is formed in the inner side wall, close to hinges, of the door frame. One side wall of the strip-shaped groove is evenly and fixedly connected with buffer springs. One ends of the buffer springs are fixedly connected with a fireproof barrier strip. A round cavity is formed in the inner side wall, away from the hinges, of the door frame. A fireproof softrubber roller is rotationally connected between the inner bottom and the inner top of the round cavity through a rotating shaft. The peripheral side face of the fireproof soft rubber roller penetratesthrough the outer portion of the inner side wall of the door frame and is in rolling connection with the side face of the door plate. Through the design of the strip-shaped groove, the buffer springs, the fireproof barrier strip and the fireproof soft rubber roller, a gap generated after the edge of the door plate is wrapped can be blocked conveniently, and the problems that the edge of an existing fireproof door is prone to suffering from wrapping, bending and other deformation, consequently, gaps happen to the fireproof door, safety protection performance is reduced, and the fireproof effect is poor are avoided.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a fire door edge sealing structure. Background technique [0002] Fire doors are common openable and closed 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 is determined. [0003] Existing fire doors are prone to deformation such as warping and bending when the temperature is high, resulting in gaps in the fire doors, and flames or thick smoke are easy to escape from the gaps, thereby reducing the safety protection performance, and the fire prevention effect is poor. Accident prone. Contents of the invention [0004] The purpose of the present invention is...
