Problems solved by technology

Not only the production and installation cost of the fire shutter itself is very high, but also the installation location is limited, which cannot form a sufficient and ideal fire protection area, and the repair and maintenance costs during use are also quite high
Since the steel fireproof shutter itself is very heavy, it cannot be stretched freely when a fire occurs, so that the fire and smoke cannot be blocked in time when multiple tunnel fires occur, so that the entire tunnel is filled with smoke and fire. caused many casualties

Abstract

The invention relates to a tunnel fire-proof rolling shutter, which comprises a front-end fixing component, more than two rolling shutter pieces, a rear-end fixing component and a trigger device, and the front-end fixing component and the rear-end fixing component are both fixedly installed in the hole of the tunnel The roof and the hole wall, one end of the shutter sheet is connected to the front-end fixing assembly, and the other end is connected to the rear-end fixing assembly, and the shutter sheets are partially overlapped in sequence, and the trigger The device is installed on the hole wall of the tunnel, and is connected with the rolling shutter sheet through the rear end fixing component. The number of fire shutters in the tunnel can be determined according to the actual length and needs of the tunnel. The invention is low in cost, low in maintenance and repair costs, simple in structure, light and convenient, easy to install and use, convenient and flexible, purely mechanical structure, easy to manufacture, low in failure rate, safe and reliable, energy-saving and environmentally friendly, easy to operate, and can promptly and quickly block fires And smoke, easy to escape.

Description

technical field [0001] The invention relates to a tunnel fireproof roller shutter. Background technique [0002] Generally, the special-purpose expressway tunnel fire shutter is a steel fire shutter with an escape door. All fire shutters are prone to derailment, and the escape door is easy to collapse or even completely collapse. Not only the production and installation cost of the fire shutter itself is very high, but also the installation location is limited, which cannot form a sufficient and ideal fire protection area, and the repair and maintenance costs during use are also quite high. Since the steel fireproof shutter itself is very heavy, it cannot be stretched freely when a fire occurs, so that the fire and smoke cannot be blocked in time when multiple tunnel fires occur, so that the entire tunnel is filled with smoke and fire. caused many casualties. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tu...
