Smoke vertical wall is installed in the ceiling or floor or hidden in the ceiling, fire can prevent smoke and hot gas horizontal flow of the vertical divider. Smoke vertical wall is used in large-scale shopping malls and supermarkets. It is the necessary smoke-proof equipment in the crowded area of the building fire protection code. It is mainly used in high-rise or super-high-rise large-scale shopping malls, office buildings and warehouses, etc. . It can effectively block the lateral flow of smoke under the roof of buildings, so as to improve the smoke exhaust effect in the smoke control zones, it will play a positive role in ensuring the safety of people's lives and property.

The technical performance requirements: 

1, appearance 

(1) the sign of the smoke screen should be firm, the sign should be clear. 

(2) no cracks, craters and obvious defects such as bump, hammer marks, burrs and holes are allowed on the surface of the metal parts with smoke-proof vertical walls, there shall be no mottling or flowing. 

(3) there are no defects of tear, corner gap, patch, hole, incline, jumper, broken thread, obvious uneven density of warp and weft yarn and color difference in the vertical wall of rolling shutter type smoke screen; Its surface should be straight, clean, beautiful. 

(4) no dislocations are allowed in the assembly and splicing of the parts.

2. Materials and parts: all kinds of raw materials used in smoke-screen vertical wall must conform to the relevant national standards or industry standards.

    The main material of fixed transparent fire-proof glass is high-strength single-piece fire-proof glass, which can keep the integrity and heat insulation of smoke-proof wall in the specified fire-proof time test. The product has the advantages of good smoke-proof effect, convenient installation and low cost. It not only conforms to the national fire-proof design specifications, but also has good permeability due to the use of fully transparent glass panels, the biggest characteristic is the beautiful degree is good, may satisfy the indoor decoration design the request maximally. Its extensive use in the flow of people, logistics is not large, but the requirements of high decoration places, such as high-end hotels, conference centers, cultural centers, high-end office buildings, etc. , its disadvantage is that the whole smoke retaining wall will collapse when it is impacted by external force, and it will injure or destroy the people or equipment below..

    A fixed or movable smoke barrier made of non-combustible material that hangs not less than 500mm from the ceiling. The movable smoke-blocking vertical wall refers to the smoke-blocking vertical wall that automatically droops due to the effect of temperature-sensing, smoke-sensing or other control equipment in fire. The fire-resistant fiber cloth is used for rolling curtain type smoke-blocking vertical wall, which is usually curled above the ceiling or fixed on the ceiling, fall automatically in case of fire. Widely used in the subway, high-rise buildings, underground garages and other places smoke division.
