(2) Guide rail

2.1 The depth of the curtain embedded in the guide rail should meet the following requirements:

2.3 Guide rails with smoke prevention performance must have smoke prevention devices. The materials used should be non-combustible materials. The smoke-proof device and the roller blind table should be evenly and closely fitted, and the bonding surface should not be less than 80%. 2.2 The top of the guide rail shall be rounded and its length shall be at least 75 mm beyond the opening.

2.4 The slideway of the guide rail shall be smooth and straight. The straightness shall not exceed 1.5mm per meter, and the straightness of the full length shall not exceed 0.12%. No distortion, bump or burr shall be allowed.

2.5 On-site installation of the guide rails should be firm. The verticality after installation should not exceed 5mm per meter, and the vertical length of the full length should not exceed 20mm.

2.6 The roller blind should run smoothly and smoothly in the guide rail, and no collision or impact is allowed.

(3) Threshold

3.1 The structure of the threshold must effectively prevent the spread of fire.

3.2 Thresholds with smoke resistance, smoke control devices must be installed to effectively prevent smoke from spilling out. All materials of smoke control devices should be non-combustible materials.

3.3 The door smoke prevention device shall be in uniform contact with the sealing surface of the sill and the surface of the roller blind. The contact surface shall not be less than 80% of the width of the door opening, and the gap of the non-contact surface shall not be greater than 2 mm.

3.4 The installation of the door sill shall be firm and the distance between the pre-buried steel parts shall not exceed 600mm.

(4) seat plate
