A pre-embedded frame fire door with supporting function

Abstract

The invention discloses a pre-embedded type frame fireproof door with a support effect. The pre-embedded type frame fireproof door comprises a doorframe structure and a door leaf structure. The doorframe structure is pre-embedded in an installation wall and comprises an upper doorframe, a left doorframe, a right doorframe and a lower doorframe. The upper doorframe, the left doorframe, the right doorframe and the lower doorframe are welded end to end to form a rectangular frame, and the door leaf structure is rotationally connected in the rectangular frame of the doorframe structure. A limitingstructure is installed on the side, close to the inner side end face of the door leaf structure, of the bottom face of the door leaf structure. According to the pre-embedded type frame fireproof door, the doorframes of the fireproof door and the wall can be fixedly installed in a pre-embedded type connection mode, thus no gap exists when the doorframes are installed on the wall, the support effect is achieved on the wall, fireproof performance of installation and use of the fireproof door is promoted, potential safety hazards in specific use are lowered, and the support effect of an existingfireproof door on the wall is extended accordingly.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a pre-embedded frame fire door with a supporting function. 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. It can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. Fire doors are an important part of fire protection equipment and an important part of social fire prevention. Fire doors should be equipped with fire door closers or door closing devices that allow normally open fire doors to automatically close the door leaf when a fire occurs. [0003] However, when the existing fire doors are installed and used, the door frame is usually fixed in the body of wall through the fixture, an...

Problems solved by technology

[0005] The purpose of the present invention is to provide a pre-embedded frame fire door with supporting function, which aims to improve the existing fire doors. When the specific installation and use, the door frame is usually fixed in the wall through the fixing piece, and the door frame is installed in the door frame at the same time. The installation method of the fire door leaf, this installation method not only causes the installation gap between the fire door frame and the wall during specific installation and use, but the installation airtightness of the fire door and the wall is not good, which may easily lead to a decrease in fire resistance during use. At the same time, the existing fire doors do not have the function of supporting the wall in specific use, and cannot support the wall in a high temperature environment, which poses a high safety hazard.
