木质防火门和钢制防火门有什么不一样？

1. There are differences in materials.

木制防火门是木制的。门框、门板一般都采用木材，其耐火性能符合有关规定。

Wooden fire doors are made of wood. Wood is generally used for door frame and door panel, and its fire resistance meets relevant regulations.

钢制防火门是钢制的。除门框外，其骨架、面板、填料等均要求为无毒环保的防火保温材料，其次为五金配件，形成符合规定的防火门。

Steel fire doors are made of steel. In addition to the door frame, its skeleton, panel, filler, etc. are required to be non-toxic and environment-friendly fire insulation materials, followed by hardware accessories to form a fire door that meets the regulations.

2.安装上存在差异。

2. There are differences in installation.

木质防火门安装时，门框规格距洞口小于20mm，门框埋入地下20mm。门框与墙面固定牢固，立框与支撑架应平直，角度一致，防止刨距。门框两侧不少于三个固定点，间距不超过800mm。

When installing wooden fire doors, the door frame specification shall be less than 20mm from the opening, and the door frame shall be buried underground for 20mm. The door frame shall be firmly fixed to the wall, and the vertical frame and support frame shall be straight with the same angle to prevent planing distance. There shall be no less than three fixed points on both sides of the door frame, and the spacing shall not exceed 800mm.

钢制防火门安装时，应考虑门框的弯曲变形。门框的宽度方向需要木支撑。门框应埋在地下20 mm处。嵌入门框和墙壁中的部件应进行焊接。门框上方的墙壁应打开，并用掺有水泥、砂和膨胀珍珠岩的混凝土填充。固化后即可使用。

When installing the steel fire door, the bending deformation of the door frame shall be considered. The width direction of the door frame needs wood support. Door frames shall be buried 20 mm underground. Components embedded in door frames and walls shall be welded. The wall above the door frame shall be opened and filled with concrete mixed with cement, sand and expanded perlite. It can be used after curing.

3.性能要求存在差异。

3. There are differences in performance requirements.

木质防火门门框及厚度应大于50mm，门扇采用双榫连接。门框与门扇拼接时，榫槽应嵌紧，用橡胶拼接，用橡胶楔固定。

The frame and thickness of wooden fire door shall be greater than 50mm, and the door leaf shall be connected with double tenon. When the door frame is spliced with the door leaf, the tenon and groove shall be embedded tightly, spliced with rubber and fixed with rubber wedge.

钢制防火门门扇与门框的搭接不小于10mm，两侧门扇与门框的间隙不大于4mm。安装后间隙不得过大。密封性能将受到影响，火灾和烟雾将无法被阻止。

The overlap between steel fire door leaf and door frame shall not be less than 10mm, and the gap between door leaf and door frame on both sides shall not be more than 4mm. The clearance shall not be too large after installation. The sealing performance will be affected and fire and smoke will not be stopped.
