New type double-track double-curtain fire resistance rolling shutter door

Abstract

The invention provides a new type double-track double-curtain fire resistance rolling shutter door, comprising two same rolling shutter door bodies, double-groove guide rails, fire resistance rolling door machines, first reels and second reels, automatic sprinkler protection devices, and a controller, wherein the upper end of each rolling shutter door body is respectively fixed on a first reel and a second reel, two sides of the rolling shutter door body are installed in the double-groove guide rails and can move up and down; each automatic sprinkler protection device comprises a first water pipe fixed at the bottom of the outside of a fire resistant box cover and connected with a fire-prevention pipe, a plurality of rotatable shower nozzles are arranged on the first water pipe for realizing water spraying protection, a magnetic valve is connected between the first water pipe and the fire-prevention pipe; the controller is located at the same side where the fire-prevention pipe is loacated, and is connected with a temperature sense probe in a matching manner, the on-off of the magnetic valve is controlled by a relay according to temperature variation. The automatic sprinkler protection devices are additionally installed at the tops and two sides of the rolling shutter doors, so that not only is the temperature of the rolling shutter door lowered, but also the role of fire active fighting is realized, and the fire behavior extending to the direction of the rolling shutter door is slowed down.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a novel double-track double-curtain fireproof rolling door. Background technique [0002] Fire shutter door is a kind of fire prevention and heat insulation facility suitable for large openings of buildings. In addition to the function of ordinary doors, it also has special functions of fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. Fire shutter curtain Through the transmission device and the control system, the rolling shutter can be lifted to realize the fire partition, so as to control the fire within the predetermined range, so as to effectively prevent the fire from spreading, ensure the safe evacuation of people, and the smooth passage of firefighters to fight the fire. Preventing and reducing the loss of people's lives and national property caused by fire is an indispensable fire prevention facility in modern...

Problems solved by technology

[0003] Since steel fire shutters cannot meet the requirements of separation of fire compartments and are heavy in weight, they cannot fully meet the fire protection needs of modern buildings. In recent years, with the entry of inorganic fiber fire shutters into the market, steel fire shutters have "ruled" The situation in the market was quickly broken. Due to the low backfire temperature of the inorganic fire-resistant shutter, low weight, small footprint, and the ability to reduce the load-bearing capacity of the building, many places currently require the use of inorganic super-grade fire-resistant shutter doors, which makes the steel fire-resistant shutter. The amount used is less and less, and inorganic super fire shutters are widely used

Among them, the double-track double-curtain fire-proof and heat-insulating roller shutter is mainly used as the fire-fighting partition device, but there are many problems in the existing double-track double-curtain inorganic fire-proof rolling door, such as the material of the fire-receiving surface is not high in temperature resistance, and there is a gap between the curtain surface and the guide rail. The gap cannot prevent the smoke from overflowing, and there is no fire extinguishing protection device, so it cannot achieve better coordination of fire protection
