Abstract

The invention discloses a composite steel fireproof roller shutter door, and relates to the technical field of fireproof roller shutter doors. According to the technical scheme, the composite steel fireproof roller shutter door is characterized by comprising a door frame and a shutter plate, wherein a reel is rotatably connected to the upper end of the door frame; the upper end of the shutter plate is fixedly connected to the reel; guide grooves allowing the two ends of the shutter plate in the horizontal direction to be embedded and move are formed in the opposite inner sides of the door frame in the vertical direction; fireproof sealing pieces are arranged on the inner side walls of the guide grooves; each fireproof sealing piece comprises a fireproof sealing strip and a fireproof air bag; the fireproof sealing strip is arranged on the inner side wall of the corresponding guide groove in the vertical direction; the section of the fireproof sealing strip is in a U shape; the fireproofair bag is arranged in a U-shaped cavity of the fireproof sealing strip; and sodium bicarbonate is arranged in the fireproof air bag. The fireproof sealing pieces are arranged, when fire is close tothe fireproof roller shutter door, the fireproof air bags are heated to expand, so that the fireproof sealing strips are tightly attached to the end face of the shutter plate, the sealing performanceof the shutter plate and the guide grooves is enhanced, thus smoke penetrating from the two sides of the roller shutter door is reduced, and the smoke isolation effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of fireproof rolling doors, more specifically, it relates to a composite steel fireproof rolling door. Background technique [0002] Composite steel fire shutter doors are composed of double-layer steel curtain panels filled with fire protection materials. The curtain panels are all made of steel plates, and each unit of the curtain panel is formed by compounding two layers of steel plates, and the fire protection material is filled between the two layers of steel plates. [0003] For example, the Chinese invention patent whose patent number is CN108533151A discloses a steel fireproof rolling door, including a rolling door, a frame, a reel, a guide rail, a door panel and a rotating shaft, a frame is installed on the front surface of the rolling door, and a reel is installed on the top of the rolling door. The middle part of the inner side is provided with a guide rail, the bottom of the shaft is fixedly con...
