| Abstract: | Based on the analysis of the advantages and disadvantages of the fire wall being replaced by the steel fire shutter in the fire compartment of high rise building and large scale construction, the article further analyzes the fire proof property of the fire shutter and further lists the fire protection problems in the steel element of the double-rail fire shutter. It is suggested that the steel element of the shutter should be fully coved by silicic calcium fire board. |
