钢门（包括防火门）安装作业指导书 Installation instruction of steel door (including fireproof door) 一、安装前准备 Preparation for installation 安装前安装单位要准备好以下工具及材料： Prepare follow tools and materials before installation 工具：电焊机、橡皮锤、铁锤、钢凿、对拔木楔、托线板、吊线坠、水平尺（或激光水平仪）、钢卷尺、角尺、粉线包。 Tools: electric welding machine, rubber hammer, iron hammer steel chisel, fixed timber, line support plate, plummet,level ruler, steel roll ruler, angle ruler, line bag. 辅助材料：预埋铁件、电焊条、连接板（垫铁）、水泥砂浆、岩棉或矿棉。 Subsidiary material: built-in iron, electric welding strip, connect plate(support iron) concrete, rock cotton or mineral cotton. 2、检查洞口尺寸是否与钢门安装要求的条件相符。 Check wall to wall size whether answer for the condition of door installation. 3、有预埋铁件的洞口，还要检查洞口内预埋铁件的构造、位置和数量能否满足安装要求。 Checking built-in iron structure,location and quantity whether answer for the requirement of installatio. 4、检查钢门的规格、型号、开启方向与设计要求要一致。 Checking steel door size,model,open direction whether consist with design requirement. 5、检查钢门锁具、闭门器、铰链及连接螺栓等配套五金的数量和质量。 Checking quality and quantity of steel door lock set,closer,hinge and other assemblies. 6、基数为无下槛的钢门，其洞口两侧地面须预留凹槽，以便埋入防火门两边框的下端；若有槛则在地面留出槽口，以便安装防火下槛。 Leave rabbet for the installation of door with threshold,it will be facilitated for threshold installation. 二、安装步骤： Installation step: 划线定位：根据甲方提供的三线（水平线，中心线，完成线）的要求划出定位线，按设计图纸规定尺寸、标高和开启方向在洞口内用“托线板”弹出门框的安装位置线。 Line oriented: line oriented according to three line(level line, central line,finishing line) which provide by Part A. (need figure) 门框安装： Door frame installation: ⑴ 立框定位校正：用对“拔木楔”将门框定位，然后用“吊线锤”吊垂直线调整门框的水平和垂直及与内外墙面的位置，门框竖框对地面的垂直误差不能大于2mm。 （需插图） Erect frame for emendation: fix door frame by fixed timber,and then adjust its location between level and erect by plummet ,the erect error of frame don’t exceed 2mm. (need figure). ⑵ 检查：测量门框槽口尺寸（长、宽、对角线），将其调整到与设计要求一致。 Checking: adjust the frame rabbet size(length,width, diagonal)till it meet the design requirement. ⑶ 连接固定：固定前对门框的位置进行复核，以保证安装尺寸准确，框口上下尺寸允许误差≤1.5mm。对角线允许误差≤2mm，并
