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

Embodiment Construction

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0049] A new type of tunnel fire shutter, such as Figure 1 to Figure 21 As shown, it includes a front-end fixing component, more than two rolling shutter sheets 1, a rear-end fixing component and a trigger device. One end of the rolling shutter sheet 1 is connected to the front-end fixing assembly, and the other end is connected to the rear-end fixing assembly, and the rolling shutter sheet 1 is partially overlapped in sequence, and the trigger device is installed in the tunnel On the wall of the hole, and connected with the roller blind sheet through the rear end fixing component.

[0050] The front-end fixing assembly includes a front-end fixing guide rail 2, a T-shaped curtain fixing part 3 and a guide rail end f...

Abstract

The invention relates to a novel tunnel fireproof roll shutter. The novel tunnel fireproof roll shutter comprises a front-end fixing assembly, two or more roll shutter pieces, a rear-end fixing assembly and a triggering device, wherein the front-end fixing assembly and the rear-end fixing assembly are both fixedly installed on the top and the wall of a tunnel, one end of each roll shutter piece is connected with the front-end fixing assembly, the other end of each roll shutter piece is connected with the rear-end fixing assembly, the roller shutter pieces are sequentially and partially overlapped, and the triggering device is installed on the wall of the tunnel and is connected with the roller shutter pieces through the rear-end fixing assembly. The number of the fireproof roller shutters in the tunnel is determined according to the actual length of the tunnel and needs. The novel tunnel fireproof roll shutter is low in cost, low in maintenance cost, simple in structure, light, convenient and rapid to use, easy to install and use, flexible, of a pure mechanical structure, easy to manufacture, low in failure rate, safe, reliable, convenient to operate and capable of rapidly blocking fire and smoke, saves energy, protects the environment, and allows people to escape easily.

Description

technical field [0001] The invention relates to a novel tunnel fireproof 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 new...
