fire shutter door

Abstract

The invention provides a fireproof rolling shutter door. The fireproof rolling shutter door comprises a guide rail, a shutter body and a winding device; the shutter body is positioned in the guide rail; the winding device comprises a door winding machine and a winding shaft; a driving shaft of the door winding machine drives a rotating shaft of the winding shaft; the winding shaft is fixedly connected with the shutter body; the shutter body comprises a support piece, a first shutter surface, a second shutter surface, a fireproof bar and a bottom beam; the first shutter surface is outwards provided with a first inorganic fiber cotton, first inorganic fiber cloth and first silica gel cloth in sequence from the support piece; the second shutter surface is outwards provided with a second inorganic fiber cotton, second inorganic fiber cloth and second silica gel cloth in sequence from the support piece; the first shutter surface and the second shutter surface are respectively positioned on two sides of the support piece; the fireproof bar is arranged between the support piece and the first shutter surface; the fireproof bar is arranged between the support piece and the second shutter surface; and the bottom beam is connected between the bottom of the first shutter surface and the bottom of the second shutter surface. The fireproof rolling shutter door has the advantages of simple structure, excellent fire resistance, thermal insulation and flame isolation effect and excellent fire resistance.

Description

technical field [0001] The invention relates to the technical field of rolling doors, in particular to a fireproof rolling door. Background technique [0002] With the development of national modernization, various types of industrial buildings are developing rapidly. During the construction process, people pay more and more attention to the prevention of fire, especially. The fire shutter doors are mainly used in the fire compartments of various industrial, civil and public buildings. They are used for the special functions of fire prevention, smoke isolation, suppression of fire spread, and protection of personnel evacuation. They are widely used in high-rise buildings and large shopping malls. And other crowded occasions. [0003] In addition, compared with ordinary rolling doors, fire-resistant rolling doors have stricter requirements on fire protection. They must meet the requirements of national standards and regulations for TF3 fire protection ratings. The temperatur...

AI Technical Summary

Problems solved by technology

For example, the material on the fire-facing surface is not high in temperature resistance, and only absorbs heat without releasing heat; the sewing of the curtain surface is not temperature-resistant, and it is prone to fall apart and off-line when encountering fire; There are easy gaps between the curtain surface, the curtain body and the guide rail, which cannot prevent the smoke from overflowing, etc.

It can be seen that the above shortcomings will reduce the fire prevention, heat insulation and flame isolation effect of the fire shutter door, and affect the fire resistance of the fire shutter door
