耐火窗安装注意事项：

Precautions for installing fire-resistant windows:

(1). 耐火窗安装按设计预留洞口的尺寸，不应该将耐火窗的外框直接就埋入墙体，否则将会影响整体的窗墙契合度，那么以后的使用会受到影响。

(1).  The installation of fire-resistant windows should be based on the size of the reserved openings in the design. The outer frame of the fire-resistant window should not be directly embedded in the wall, otherwise it will affect the overall fit between the window and the wall, and its future use will be affected.

(2). 对于轻质墙体材料砌成的洞口，应提前在连接处或洞口周边作相应处理，确保**性连接，不能把连接件直接与轻质砌块连接固定。

(2).  For openings made of lightweight wall materials, corresponding treatment should be carried out in advance at the connection or around the opening to ensure a reliable connection. The connecting components should not be directly fixed to the lightweight blocks.

(3). 安装塑料门窗五金配件时，应将螺钉固定在内衬增强型钢或内衬局部加强钢板上，或使螺钉至少穿过塑料型材的两层壁厚，确保其稳定不易发生变形等情况。

(3).  When installing plastic door and window hardware accessories, screws should be fixed on the reinforced steel or locally reinforced steel plate of the lining, or the screws should pass through at least two layers of the plastic profile wall thickness to ensure stability and prevent deformation.

(4). 推拉式耐火窗窗扇安装设置可调整限位卡等防脱落措施，限位卡适宜安装在窗扇侧面的上方。推拉式耐火窗安装后框扇应无可视变形，开关非常灵活，门扇关闭严密。

(4).  The installation of push-pull fire-resistant window sashes is equipped with adjustable limit cards and other anti fall measures. The limit cards are suitable for installation above the side of the window sash. After installation, the frame of the sliding fire-resistant window should have no visible deformation, the switch should be very flexible, and the door leaf should be tightly closed.
