一、电梯门套：电梯的 “脸面” 和 “防护盾”

　　1、 Elevator door frame: the "face" and "protective shield" of the elevator

　　想象一下，电梯门就像家里的大门，门套就是门框 —— 既得好看，又得能扛住每天上百次的开关碰撞。合格的电梯门套得像医院的无菌门一样严丝合缝，又得像银行金库门一样结实耐用。制作标准里藏着哪些让门套 “颜值与实力并存” 的秘密？

　　Imagine that the elevator door is like the main entrance of a home, with the door frame being the door frame - it has to look good and withstand hundreds of switch collisions every day. A qualified elevator door frame should fit tightly like a sterile hospital door, and be as sturdy and durable as a bank vault door. What are the secrets hidden in the production standards that allow door frames to have both appearance and strength?

　　二、选材篇：门套 “骨架” 决定寿命

　　2、 Material selection article: The "skeleton" of the door frame determines its lifespan

　　1. 不锈钢：电梯门套的 “钢铁战士”

　　1. Stainless steel: the "steel warrior" of elevator door frames

　　厚度标准：至少用 1.2mm 厚的 304 不锈钢，像硬币厚度的 2 倍，用手按不会凹进去；

　　Thickness standard: Use at least 1.2mm thick 304 stainless steel, which is twice the thickness of a coin, and will not sink in when pressed by hand;

　　防锈测试：滴一滴盐水在表面，24 小时后擦干净，合格的不锈钢不会出现锈点（就像海边的栏杆不生锈）。

　　Rust prevention test: Drop a drop of salt water on the surface and wipe it clean after 24 hours. Qualified stainless steel will not have rust spots (just like the railing on the beach does not rust).

　　2. 石材：高端电梯的 “大理石外衣”

　　2. Stone: The "marble coat" of high-end elevators

　　材质要求：必须选花岗岩（如芝麻黑），硬度比瓷砖高 3 倍，用钥匙划不会留痕；

　　Material requirements: Granite (such as sesame black) must be selected, with a hardness three times higher than ceramic tiles, and will not leave any marks when scratched with a key;

　　厚度底线：地面以上门套石材厚度≥20mm，地坎处要≥30mm，防止被行李箱撞裂。

　　Thickness bottom line: The stone thickness of the door frame above the ground should be ≥ 20mm, and at the sill, it should be ≥ 30mm to prevent it from being cracked by luggage.

　　3. 木质门套：住宅电梯的 “温柔选择”

　　3. Wooden door frame: the "gentle choice" for residential elevators

　　木材种类：优选榉木或胡桃木，密度高像硬木家具，用指甲掐不会留印；

　　Wood type: preferably beech or walnut, with a high density similar to hardwood furniture, will not leave marks when pinched with nails;

　　防潮处理：木材必须泡过防水剂，像给木头穿雨衣，泡水 24 小时膨胀率≤1%。

　　Moisture proof treatment: Wood must be soaked in a waterproof agent, such as wearing a raincoat on wood, and the expansion rate after soaking in water for 24 hours should be ≤ 1%.

　　三、尺寸篇：差 1 毫米就可能 “卡门”

　　3、 Size article: A difference of 1 millimeter could lead to 'Carmen'

　　1. 门套垂直度：比门框还严格的 “身材管理”

　　1. Verticality of door frame: stricter "body management" than door frame

　　标准要求：每米垂直度误差≤1mm，用靠尺测量时，缝隙塞不进 A4 纸（类似贴瓷砖不能歪）；

　　Standard requirement: The verticality error per meter is ≤ 1mm. When measuring with a ruler, the gap cannot be filled with A4 paper (similar to tiling, it cannot be tilted);

　　后果警示：某小区电梯门套歪了 3mm，导致电梯门开关时 “咯噔” 响，修了半个月。

　　Consequence warning: The elevator door frame in a certain residential area was misaligned by 3mm, causing a "clunking" sound when the elevator door was opened and closed. It was repaired for half a month.

　　2. 对角线误差：像量正方形一样精准

　　2. Diagonal error: as precise as a square

　　测量方法：用卷尺量门套对角线，两边长度差≤2mm，否则门会关不严（类似家里衣柜门歪了关不上）；

　　Measurement method: Use a tape measure to measure the diagonal of the door frame, with a length difference of ≤ 2mm on both sides, otherwise the door will not close tightly (similar to a crooked wardrobe door at home that cannot be closed);

　　施工技巧：安装时用激光水平仪打线，误差比头发丝还细（0.5mm 以内）。

　　Construction technique: Use a laser level to mark the line during installation, with an error smaller than a hair thread (within 0.5mm).

　　3. 地坎间隙：防止夹鞋的 “安全距离”

　　3. Gap between sills: a "safe distance" to prevent shoe pinching

　　标准规定：门套地坎与电梯门之间缝隙≤4mm，能塞进铅笔但塞不进手指（避免高跟鞋卡住）；

　　Standard requirement: The gap between the door sill and the elevator door should be ≤ 4mm, and a pencil can be inserted but not fingers (to avoid high heels getting stuck);

　　某商场案例：缝隙太大夹坏过女士凉鞋，整改后用 4mm 厚的塞尺检查，确保万无一失。

　　A certain shopping mall case: The gap was too large and damaged women's sandals. After rectification, a 4mm thick feeler gauge was used for inspection to ensure that everything was foolproof.

　　四、安装篇：三步装出 “稳如泰山” 的门套

　　4、 Installation: Three step installation of door jamb "as stable as Mount Tai"

　　1. 基层处理：给门套 “打地基”

　　1. Grassroots treatment: lay the foundation for the door frame

　　墙面要求：用水泥砂浆找平，平整度误差≤3mm，像铺地板前要找平地面；

　　Wall requirements: Use cement mortar for leveling, with a flatness error of ≤ 3mm. Before laying the floor, the ground should be leveled;

　　固定方式：用膨胀螺栓固定基层钢架，间距≤30cm，每个螺栓能扛 50 公斤拉力（相当于吊住一袋水泥）。

　　Fixing method: Use expansion bolts to fix the base steel frame with a spacing of ≤ 30cm. Each bolt can withstand a tensile force of 50 kilograms (equivalent to hanging a bag of cement).

　　2. 面板安装：像拼乐高一样精准

　　2. Panel installation: as precise as assembling Lego bricks

　　不锈钢门套：板材之间用折边扣合，缝隙≤0.5mm，用手摸感觉不到台阶（类似手机边框的无缝衔接）；

　　Stainless steel door frame: The plates are fastened with folded edges, with a gap of ≤ 0.5mm, and the steps cannot be felt by hand (similar to the seamless connection of a phone frame);

　　石材门套：板块之间用 AB 胶 + 不锈钢挂件双重固定，抗震测试时，8 级地震模拟下不会脱落。

　　Stone door frame: The panels are double fixed with AB glue and stainless steel hangers, and will not fall off during seismic testing under a simulated earthquake of magnitude 8.

　　3. 密封处理：给门套 “穿雨衣”

　　3. Sealing treatment: put a raincoat on the door frame

　　缝隙填充：用中性硅酮密封胶填缝，颜色要和门套一致，挤胶时要像拉面条一样均匀；

　　Gap filling: fill the gap with neutral silicone sealant, the color should be consistent with the door pocket, and the extrusion should be as uniform as the Lamian Noodles strip;

　　防水测试：往缝里喷水 5 分钟，背面不能渗水（类似卫生间防水测试）。

　　Waterproof test: Spray water into the seam for 5 minutes, and there should be no water seepage on the back (similar to a bathroom waterproof test).

　　五、验收篇：四招判断门套合不合格

　　5、 Acceptance section: Four methods to determine whether the door frame is qualified or not

　　1. 看外观：像选衣服一样挑 “颜值”

　　1. Look at appearance: Choose "looks" like choosing clothes

　　检查方法：站在 1 米外看，门套表面不能有划痕、气泡，拼接处颜色要一致（像看瓷砖是否有色差）；

　　Inspection method: Standing 1 meter away, the surface of the door frame should not have scratches or bubbles, and the color of the joints should be consistent (such as checking whether there is color difference in the tiles);

　　不合格案例：某写字楼门套有焊接黑斑，返工打磨 3 次才达标。

　　Unqualified case: There are welding black spots on the door frame of a certain office building, which need to be reworked and polished three times before reaching the standard.

　　2. 摸手感：比摸家具还讲究

　　2. Touch sensation: More important than touching furniture

　　测试方式：用手掌从门套顶部摸到底部，不能有毛刺、凹凸感，转角处要圆润（类似摸婴儿玩具的边角）；

　　Testing method: Use your palm to touch the door frame from top to bottom, without any burrs or bumps, and the corners should be rounded (similar to touching the corners of a baby toy);

　　安全意义：尖角可能划伤老人小孩，合格门套转角弧度≥R2mm（像手机圆角）。

　　Safety significance: Sharp corners may scratch the elderly and children. The qualified door frame has a corner radius of ≥ R2mm (similar to the rounded corners of a mobile phone).

　　3. 听声音：敲一敲辨 “虚实”

　　3. Listen to the sound: knock to distinguish between "virtual and real"

　　验收技巧：用指关节轻敲门套，声音沉闷表示安装牢固，空洞声说明里面有空鼓（类似敲墙壁查空鼓）；

　　Acceptance technique: Lightly tap the door frame with fingertips. A dull sound indicates a firm installation, while a hollow sound indicates a hollow drum inside (similar to tapping a wall to check for a hollow drum);

　　处理方法：有空鼓的地方必须拆开重装，某酒店曾因空鼓导致门套半年后脱落。

　　Solution: The area with hollowing must be disassembled and reassembled. A hotel once had its door frame fall off after six months due to hollowing.

　　4. 测功能：开关门像滑滑梯一样顺

　　4. Testing function: Opening and closing the door is as smooth as a slide

　　测试流程：连续开关门 50 次，门套不能有异响、卡顿，门缝宽度始终一致（像抽屉推拉顺畅）；

　　Test process: Open and close the door continuously 50 times, without any abnormal noise or jamming of the door frame, and the width of the door gap is always consistent (like smooth sliding of a drawer);

　　关键数据：开关门阻力≤50N，相当于提 5 公斤大米的力气，老人小孩都能轻松推动。

　　Key data: The resistance of opening and closing the door is ≤ 50N, which is equivalent to the force of lifting 5 kilograms of rice. Both the elderly and children can easily push it.
