Special fireproof inorganic double-track double-shutter rolling door

Abstract

The invention discloses a special fireproof inorganic double-track double-shutter rolling door. The rolling door comprises shutter surfaces, guide rails, a pedestal plate, rollers, a fireproof door roller and a fireproof rolling controller. The rolling door has the following beneficial effects: the shutter surfaces are formed by overlapping multiple layers of materials with corresponding functions, so that the temperature rise can be effectively reduced; the loads of the shutter surfaces are hung by steel wire ropes, so that the service life can be prolonged, and breakages caused by fire can be prevented; the installation cascade structures of the two shutter surfaces can be reversely installed, so that fire coming from different directions can be effectively prevented; the two rollers are controlled by a same shutter rolling machine, so that resources can be saved; reflecting cloth is additionally arranged in the shutter surfaces, so that heat added to the shutter surfaces can be effectively reduced; by arranging smoke control devices in the guide rails, sealing strips are swollen after heated, and gaps between the shutter surfaces and the guide rails can be extruded and eliminated; by additionally arranging expansion spray devices in the guide rails, after water which is contained in cavities of ear channels is swollen after being heated the bottom walls of small holes can be extruded and punched, so that the water in the cavities of the ear channels can be sprayed to the shutter surfaces, the temperatures of the shutter surfaces can be reduced, and the fire-resistant time can be effectively prolonged.

Description

technical field [0001] The invention relates to a fireproof rolling door, in particular to a double-track double-curtain inorganic super fireproof rolling door. Background technique [0002] Compared with ordinary rolling doors, fire-resistant rolling doors have higher requirements on fire protection. They must meet the requirements of national standards and regulations for TF3 fire protection ratings. The temperature rise of the back-fired surface is used as the judgment condition, and the fire-resistant rolling shutters with a fire resistance limit of not less than 3H are special grades. Fireproof Shutter. [0003] In order to meet the requirements of super fire protection, various products have been produced. The more popular ones are aerosol fire shutter door, evaporative fire shutter door, double-track double curtain inorganic fire shutter door, water service type fire shutter door, etc. These shutter doors have their own characteristics, and generally It can meet the ...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many problems in the existing double-track double-curtain inorganic fire-proof rolling doors, such as the material on the fire surface is not high in temperature resistance, and only absorbs heat without releasing heat, and the sewing thread on the curtain surface is not temperature-resistant, and it is easy to fall apart when it encounters fire. There is a gap between the curtain surface and the guide rail, which cannot prevent the smoke from overflowing. The functions of the double curtains are exactly the same, and it is impossible to achieve a better coordinated fire protection effect.
