Abstract

The invention discloses a fireproof partition door structure, comprising a door frame with a door opening, and a door leaf hinged with the door frame, the door leaf is used to open or close the door opening; the door leaf includes a first door panel and a second door panel arranged in parallel and at intervals, and The door frame connected between the first door panel and the second door panel, the outer wall surface of the first door panel forms a fire receiving surface, the door edges of the first door panel and the second door panel are equipped with sealing strips, and the sealing strips are along the periphery of the corresponding door panels Extending to the door edge of the corresponding door panel; the sealing strip includes a U-shaped clamping part in cross section, and a hollow sealing part connected with the clamping part. The door edge of the door panel is clamped in the U-shaped groove of the clamping part and is hollow The sealing part is used to abut against the door frame, so that a seal is established between the door edge and the door frame. The fireproof partition door has good structural sealing, meets the requirements of fireproof heat insulation and integrity, and has the advantages of simple structure, convenient installation, easy maintenance, and high safety.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a fireproof partition door structure. Background technique [0002] At present, the existing locomotive partition wall structure in China only has the functions of connecting the driver's cab and equipment room / passenger room and observing and looking out. However, as the industry's requirements for safety performance increase, the corresponding standards clearly state that rail vehicles need to be equipped with fireproof partition structures. The fire partition door is set between the driver's cab and the equipment room / passenger room, and is specifically arranged at the connection between the driver's cab area and the equipment room / passenger room. In the event of a fire emergency, the function of the fireproof partition is to block the spread of the flame within a certain period of time, giving the drivers and passengers a chance to escape, and at the same time, it is n...
