How to take fire separation measures between the fire shutter and the surrounding wall
-
frequently asked questions
There is a large area of opening between the fire shutter and the floor, beam, wall, column, etc., and there is no fire separation or blocking, and the material below the fire resistance limit of the fire separation part is used for separation or blocking.
-
Regulatory basis
Clause 6.5.3 of the Code for Fire Protection Design of Buildings GB50016-2014 (2018 Edition).

Reference method
The main reason for this problem is that the installation of fire shutter is not standardized, do not pay attention to the control and sealing of the gap, the construction unit should be plugged with the fireproof sealing material used in the opening, gap, etc., after installation, so that the fire resistance limit of the overall opening part is not lower than the fire resistance limit requirements of the wall of the setting part.
Therefore, the following reference practices can be adopted:
The larger opening between the fireproof roller shutter and the floor, beam and side wall is filled with non-combustible materials such as rock wool and glass wool in the middle of the fireproof board and fireproof chain plate, and the orifice between the beam and the column is blocked with rock wool that is not lower than the fire resistance limit of the wall at the set part, so that it has smoke-proof performance.
