Abstract
A high-strength steel fireproof access door includes a door frame (1) and a door flank. The door frame (1) and the door flank (2) are hinged together through pivot hinges (3) to constitute the access door. The high-strength steel fireproof access door is characterized in that the door frame (1) comprises a hinge side upright frame (101), an upper frame (102), a lock side upright frame (103), and a door sill (104), wherein the hinge side upright frame (101), the upper frame (102), the lock side upright frame (103), and the door sill (104) are sequentially and fixedly connected to constitute the square door frame (1). The side, where the pivot hinges are arranged, of the door frame, is in a clamp groove structure. A step-shaped clamp strip is arranged on the hinge side of the door flank. After the door flank is closed, the clamp strip is embedded in the clamp groove to lock firmly. By adoption of the pivot hinges, the door flank and the door frame are convenient to install and adjust, and evenness of cracks between the door frame and the door flank is ensured. A multipoint push rod escape lock and a door shutter are arranged on the door so as to bring convenience to escape of people and automatic close of the door at emergency time.
