Roller-shutter-type fireproof door

Abstract

The invention discloses a roller-shutter-type fireproof door which comprises a fireproof reel sleeve, a roller shutter fireproof door body and a first decoration frame. A square reel is arranged outside driving key teeth, a connecting piece is welded to the front side of the square reel, and threaded mounting shafts matched with threaded fixing cylinders are arranged on the outer side of a mounting piece. Skeleton connecting strips are arranged on the two sides of the roller shutter fireproof door body correspondingly, mounting clamping blocks are arranged on the lower portions of the skeletonconnecting strips, water passing holes are formed in the middles of sliding shafts, roller shutter fireproof rods are arranged on the inner sides of mounting holes, and hydraulic pressure slopes arearranged in the middles of the roller shutter fireproof rods. A plurality of fire hydrant connecting openings are formed in the front side of the first decoration frame. The square reel is arranged outside the driving key teeth, and thus the roller shutter fireproof door body is advantageously curled and stored; the threaded mounting shafts matched with the threaded fixing cylinders are arranged on the outer side of the mounting piece, and thus the fireproof reel sleeve is advantageously fixed to a wall; the hydraulic pressure slops are arranged in the middles of the roller shutter fireproof rods, thus hydraulic pressure of different heights advantageously keeps balance; and a fireproof groove is formed in a second decoration frame, so that fire extinguishing is faster.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a rolling shutter type fire door. Background technique [0002] Existing fire doors are installed separately and are mostly installed at the entrance of stairs or corridors, while the doors of ordinary houses are not equipped with fire protection devices. As a result, when a fire occurs, the fire spreads rapidly and brings huge economic losses and personal injuries to the fire scene. . [0003] Chinese patent CN201721306357.8 discloses a fire-proof rolling shutter with a new type of fire-proof and heat-insulating escape door, including a rolling shutter device, a fire-proof rolling shutter, a fire-proof and heat-insulating escape door structure, a rolling shutter guide rail and a control device, and a fire-proof and heat-insulating escape door structure Including door frames, fireproof hinges, fireproof door leaves, composite fireproof insulation panels, fireproof door closer...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, the principle of fire prevention is basically that fire doors are flame retardant and the purpose of fire prevention is achieved through space separation. However, with the development of modern technology, the application of a batch of new materials can achieve twice the result with half the effort in function. The existing technology Insufficient consideration or abuse of new material technology leads to high cost and difficult promotion and application. In addition, the degree of automation is not high enough, and the monitoring effect and fire extinguishing effect are not ideal.
