Fireproof rolling shutter door is a kind of fire prevention and thermal insulation facility suitable for large openings of buildings. The product plays a certain role in design and installation. Fireproof rolling shutter door is widely used in the fire partition area of industrial and civil buildings. It can effectively prevent the spread of fire and ensure the safety of life and property. It is an indispensable fire prevention facility in modern buildings. There is no strict distinction between fireproof rolling shutter and fireproof rolling shutter door, and the function is the same. The full name of the fireproof rolling shutter is the fireproof rolling shutter door.

防火卷簾門的種類主要有：復合型鋼質防火卷簾（防火防煙）、無機特級防火卷簾（雙軌雙簾）、鋼質復合型水噴汽霧式防火卷簾、鋼質復合型側向式防火卷簾、鋼質復合型水平式防火卷簾、無機特級折疊式防火卷簾以及帶各種簾中門的防火卷簾。按材質分鋼質、復合、無機等。

The main types of fireproof rolling shutter doors are: composite steel fireproof rolling shutter (fire and smoke prevention), inorganic special grade fireproof rolling shutter (double track double curtain), steel composite water spray steam mist fireproof rolling shutter, steel composite lateral fireproof rolling shutter, steel composite horizontal fireproof rolling shutter, non machine special folding fireproof rolling shutter and fireproof rolling shutter with various curtain middle doors. According to the material, it is divided into steel, composite, inorganic, etc.

防火卷門如何安裝導軌1、在防火卷簾門的兩側確定導軌安裝位置，用錘線放出導軌基準線，放出導軌連接件固定螺栓十字線，導軌超過吊頂不小于75cm。

How to install the guide rail for the fireproof rolling shutter 1. Determine the installation position of the guide rail on both sides of the fireproof rolling shutter door, set out the guide rail reference line with the hammer line, set out the cross line of the fixing bolt of the guide rail connector, and the guide rail shall not exceed the ceiling by less than 75cm.

2、用沖擊鉆在墻柱上打出連接件固定膨脹螺栓孔，連接件的間 距不得大于600 mm，兩端距導軌口100 mm。先上下固幾塊連接件，將導軌貼上，校正其垂直并點焊，導固定后再復一下導軌的垂直度，每米不得大于5 mm，全長垂直度不得超過20 mm，復合簾面嵌入導軌深度(見GBl4102—2005)。

2. Use the impact drill to punch the expansion bolt hole for fixing the connector on the wall column. The spacing of the connector shall not be greater than 600 mm, and the two ends shall be 100 mm away from the guide rail opening. First fix several connectors up and down, paste the guide rail, correct its verticality and spot weld it. After the guide rail is fixed, reset the verticality of the guide rail, which shall not be greater than 5 mm per meter, and the verticality of the whole length shall not exceed 20 mm. The depth of the composite curtain surface embedded in the guide rail (see gbl4102-2005).

3、將其余連接件裝上，連接件與導軌之間采用點焊，每件連接件與一導軌間點焊點不少于5點，點焊的寬度不小于5 mm，焊接處 絕不應穿現象發生。采用不銹鋼導軌時焊條采用不銹鋼焊條。

3. Install other connectors. Spot welding shall be adopted between the connector and the guide rail. The spot welding point between each connector and a guide rail shall not be less than 5 points, and the width of spot welding shall not be less than 5 mm. The welding place shall not be penetrated. When stainless steel guide rail is used, stainless steel electrode shall be used.
