Single-shutter type steel composite thermal-insulation fire-resistance rolling shutter door

Abstract

The invention discloses a single-shutter type steel composite thermal-insulation fire-resistance rolling shutter door. The rolling shutter door comprises transmission mechanisms, a case, a slide, a guide rail and roller shutters. The transmission mechanisms comprise a main transmission mechanism and an auxiliary transmission mechanism which are mounted in the case respectively. The slide is fixed between the main transmission mechanism and the auxiliary transmission mechanism, the guide rail is perpendicularly mounted below main and auxiliary supporting plates, a lifting mechanism is arranged in the guide rails, and the roller shutters are hinged to the lifting mechanism which is connected with the main transmission mechanism and the auxiliary transmission mechanism. According to the rolling shutter door, an independent water supply system is not needed, so that a large number of water resources are saved, the rolling shutter door is convenient to design and mount, and detection can be performed according to a GB / T7633 fire resistance test method without the water curtain protection, so that 2-to-3-hour heat insulation property (the unexposed surface average temperature is lower than 140 DEG C, and the peak temperature is lower than 180 DEG C) and completeness of the rolling shutter door can be met. Shutter plates are made of non-poisonous environment friendly materials and are harmless to human.

Description

technical field [0001] The invention relates to a rolling shutter door, in particular to a single-curtain type steel composite heat-insulating fireproof rolling door. Background technique [0002] There are two types of heat-insulating fire-proof rolling doors in the fire-proof shutter market: one is the double-track double-curtain inorganic heat-insulating fire-proof rolling door, and the other is the water mist heat-insulating fire-proof rolling door. The disadvantages of the above two heat-insulating fire-proof rolling doors are as follows: [0003] The double-track double-curtain inorganic heat-insulating fireproof rolling door is made of inorganic refractory materials such as aluminum silicate fiber blanket, glass fiber cloth, ceramic fiber fireproof cloth (or high silica cloth, asbestos cloth), and radiation-proof aluminum foil cloth. A large amount of dust is produced during production, installation and transportation, and the dust is scattered in the air, which is ve...

AI Technical Summary

Problems solved by technology

[0004] The water mist heat-insulated and fire-proof rolling shutter door realizes heat insulation by spraying water on the surface of the rolling shutter to cool down the temperature through an independent water supply system. The cost of related supporting facilities is high, which brings a lot of inconvenience to design and installation. Meet energy saving requirements
