钢制防火窗就是指能够满足稳定性、完整性要求的钢质材料的防火窗。门框内填满水泥砂浆，对门框的整体刚度有着不错的承托。确保了门框不变形，这样门框和门扇间才会有相当大缝隙，使火焰冒出。

Steel fireproof windows refer to fireproof windows made of steel materials that can meet the requirements of stability and integrity. The door frame is filled with cement mortar, which provides good support for the overall stiffness of the door frame. Ensure that the door frame does not deform, so that there is a considerable gap between the door frame and the door leaf, allowing flames to burst out.

保证钢质防火窗的质量是保证进度的重要因素，若施工过程中不小心造成了局部损坏，应立即使用专用修补料修补。

Ensuring the quality of steel fireproof windows is an important factor in ensuring progress. If local damage is accidentally caused during the construction process, specialized repair materials should be used immediately for repair.

安装窗户前应对实际的尺寸再进行复核。在安装的时候应严格按照施工图上的要求、排版图的节点来进行施工。防火窗进场之后，再根据现场对窗子的规格和尺寸进行确认，并对它的外观质量进行抽检，验收查看产品的质保书和合格证等资料，保证质量有保障。

Before installing windows, the actual dimensions should be rechecked. During installation, construction should be carried out strictly in accordance with the requirements on the construction drawing and the nodes on the layout diagram. After the fireproof window enters the site, its specifications and dimensions will be confirmed based on the site, and its appearance quality will be randomly inspected. The quality assurance certificate and certificate of conformity of the product will be checked for acceptance to ensure quality assurance.

由于门体的外形和尺寸可能有一定的几何偏差，因此在安装时要根据房屋的水平控制线和平面控制线，每安装完一个窗户就进行水平高度位置和平整度的再次检查，做到横缝要水平沟通连接、平面要平整。

Due to the possible geometric deviations in the shape and size of the door body, it is necessary to check the horizontal height position and flatness again after installing each window according to the horizontal and plane control lines of the house during installation, ensuring that the horizontal joints are connected horizontally and the plane is flat.

在吊运和安装钢质防火窗的过程中，采用适当的运输和施工工具，避免人员受伤和窗子损伤。

During the lifting and installation of steel fireproof windows, appropriate transportation and construction tools should be used to avoid personal injury and window damage.
