Abstract

The invention discloses an expansion and sealing type movable fireproof door. The expansion and sealing type movable fireproof door comprises a fireproof door frame, a connection hinge and a fireproofmain bracket body, wherein the inner side of the fireproof door frame is provided with a fireproof door sheet, the left side of the fireproof door sheet is provided with the connection hinge, the fireproof door sheet is connected with the fireproof door frame through the connection hinge, the fireproof door sheet is provided with a lock, a sealing ring is arranged between the fireproof door sheetand the fireproof door frame, the inner side of the fireproof door sheet is provided with an insulated door sheet, a vertical rod is provided with a third board body, and the third board body is located in a fireproof auxiliary bracket body. The expansion and sealing type movable fireproof door has the advantages that after high-temperature combustion is carried out, the fireproof door sheet, a fireproof door frame framework, the fireproof main bracket body and the fireproof auxiliary bracket body which are made from a stainless material still provide a good protective capacity, so that a burned penetration phenomenon is avoided, thereby preventing the situations of fire spreading and flue gas leakage, and the escape time can be prolonged for related personnel, thereby improving the escape probability of the related personnel.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to an expansion-sealed movable fire door. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, it also has the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel; [0003] 1. The fireproof performance of the existing fire doors is not high. After high-temperature combustion, there will be burnt penetration, which is prone to fire spread and smoke leakage, which is not conducive to the timely escape of relevant personnel, thus improving the safety of related personnel. personal danger to persons; [0004] 2. Existing fire doors are prone to deformation after being subjected to high temperature, so th...
