潍坊电梯门套安装需兼顾安全性、美观性与耐用性，受当地气候（夏季多雨、冬季寒冷）和建筑风格影响，安装过程需注重细节把控，从前期准备到后期验收，每个环节的规范操作都直接影响最终效果与使用安全，尤其需适应本地环境特点，确保门套长期稳定使用。

　　The installation of elevator door frames in Weifang needs to balance safety, aesthetics, and durability. Due to the influence of local climate (rainy summers, cold winters) and architectural style, attention should be paid to detail control during the installation process. From early preparation to later acceptance, the standardized operation of each link directly affects the final effect and safety of use, especially adapting to local environmental characteristics to ensure long-term stable use of door frames.

　　安装前的测量与材料检查是基础，直接决定安装精度。需使用激光水平仪和卷尺精确测量电梯洞口的宽度、高度及垂直度，误差超过 5mm 需提前处理（如凿平墙体或填充修补），避免门套安装后出现缝隙或倾斜。潍坊地区建筑墙体多为混凝土或加气块，需根据墙体材质选择适配的固定件（混凝土墙体用膨胀螺栓，加气块墙体用专用尼龙锚栓），防止固定不牢导致后期松动。材料检查重点关注门套线条的平整度（弯曲度不超过 2mm/m）、表面光洁度（无划痕、凹陷），以及配套胶水的耐候性（需适应 - 10℃至 40℃温差），避免因材料质量问题影响安装效果和使用寿命。

　　The measurement and material inspection before installation are the foundation, which directly determines the installation accuracy. It is necessary to use a laser level and tape measure to accurately measure the width, height, and verticality of the elevator opening. If the error exceeds 5mm, it needs to be treated in advance (such as chiseling the wall or filling and repairing) to avoid gaps or tilting after the installation of the door frame. The walls of buildings in Weifang area are mostly made of concrete or aerated blocks, and suitable fixing parts need to be selected according to the wall material (expansion bolts are used for concrete walls, and special nylon anchor bolts are used for aerated block walls) to prevent loosening in the later stage due to weak fixation. The material inspection focuses on the flatness of the door frame lines (with a curvature not exceeding 2mm/m), the surface smoothness (without scratches or dents), and the weather resistance of the matching adhesive (to adapt to a temperature difference of -10 ℃ to 40 ℃), in order to avoid affecting the installation effect and service life due to material quality issues.

　　基层处理需适应潍坊气候特点，增强防潮与稳固性。电梯井口周边墙体常因冷凝水出现返潮，安装前需清理基层浮灰、油污，用防水砂浆抹平墙面，阴阳角做圆弧处理，干燥后涂刷防潮底漆，防止潮气渗透导致门套变形（尤其木质或复合材质门套）。对于老旧小区改造项目，需检查原洞口是否有裂缝、空鼓，空鼓面积超过 10% 需铲除重做，确保基层承载力达标。若洞口与门套间隙过大（超过 3cm），需用细石混凝土填充而非发泡剂，增强结构稳定性，抵御潍坊春季多风天气可能带来的振动影响。

　　Grassroots treatment needs to adapt to the climate characteristics of Weifang, enhance moisture resistance and stability. The walls around the elevator shaft often become damp due to condensation water. Before installation, it is necessary to clean the floating ash and oil stains on the base layer, smooth the wall surface with waterproof mortar, make circular arcs on the internal and external corners, and apply moisture-proof primer after drying to prevent moisture from penetrating and causing deformation of the door frame (especially wooden or composite door frames). For the renovation project of old residential areas, it is necessary to check whether there are cracks or hollows in the original openings. If the hollowing area exceeds 10%, it needs to be removed and redone to ensure that the grassroots bearing capacity meets the standard. If the gap between the opening and the door frame is too large (more than 3cm), it is necessary to fill it with fine aggregate concrete instead of foaming agent to enhance structural stability and resist the vibration effects that may be caused by the windy weather in Weifang in spring.

　　安装固定过程注重垂直度与牢固性，避免安全隐患。门套线条拼接处需预留 1-2mm 伸缩缝（应对温度变化引起的热胀冷缩），拼接角度保持 90°，用角尺实时校准。固定时遵循 “先上后下、先内后外” 原则，顶部线条用 2-3 个固定点，两侧线条每 50cm 设一个固定点，确保受力均匀。膨胀螺栓埋入墙体深度不小于 5cm，拧紧后做防松处理（加弹簧垫圈），防止长期使用后松动。对于不锈钢等金属门套，需注意与墙体间的绝缘处理（垫橡胶垫片），避免电化学腐蚀（潍坊空气湿度较高时更易发生），同时预留 3-5mm 安装间隙，方便后期调整。

　　During the installation and fixation process, attention should be paid to verticality and firmness to avoid safety hazards. 1-2mm expansion joints should be reserved at the junction of door frame lines (to cope with thermal expansion and contraction caused by temperature changes), with a splicing angle of 90 °, and calibrated in real time with an angle ruler. When fixing, follow the principle of "from top to bottom, from inside to outside". Use 2-3 fixing points for the top line, and set a fixing point every 50cm for both sides of the line to ensure even force distribution. The expansion bolt should be buried in the wall to a depth of not less than 5cm, and after tightening, anti loosening treatment should be carried out (with spring washers added) to prevent loosening after long-term use. For metal door frames such as stainless steel, attention should be paid to insulation treatment with the wall (using rubber gaskets) to avoid electrochemical corrosion (which is more likely to occur when the air humidity is high in Weifang), and a 3-5mm installation gap should be reserved for later adjustment.

　　密封与收口处理影响美观与防潮性能，细节决定品质。门套与墙体间隙用中性硅酮密封胶填充（避免酸性胶腐蚀金属件），胶线宽度控制在 3-5mm，表面用工具压平刮光，确保无气泡、无断缝。木质门套底部需高出地面 5-10mm，防止拖地时污水浸泡；石材门套与地面接触处做斜坡处理，引导水流远离门套。潍坊部分地区有地暖，安装时需确认门套底部与地暖管道的安全距离（不小于 10cm），避免高温导致材质变形。收口线条对接处需齐平，误差不超过 0.5mm，用同色密封胶填补微小缝隙，提升整体美观度。

　　Sealing and sealing treatment affect aesthetics and moisture resistance, while details determine quality. The gap between the door frame and the wall should be filled with neutral silicone sealant (to prevent acidic adhesive from corroding metal parts), and the width of the adhesive line should be controlled within 3-5mm. The surface should be flattened and scraped with tools to ensure no bubbles or broken joints. The bottom of the wooden door frame should be 5-10mm above the ground to prevent soaking in sewage when mopping the floor; Slope treatment should be applied to the contact area between the stone door frame and the ground to guide water flow away from the door frame. Some areas in Weifang have underfloor heating, and during installation, it is necessary to confirm the safe distance between the bottom of the door frame and the underfloor heating pipeline (not less than 10cm) to avoid material deformation caused by high temperatures. The joint of the closing line should be flush with an error of no more than 0.5mm, and small gaps should be filled with sealant of the same color to enhance the overall aesthetics.

　　安装后养护与验收需覆盖短期与长期使用需求。安装完成 24 小时内避免碰撞、重压，密封胶完全固化前（通常 72 小时）保持通风干燥，避免潮湿环境影响胶黏效果。验收重点检查：垂直度（用靠尺测量误差≤3mm）、平整度（≤2mm）、拼接处缝隙（≤0.5mm），以及开启电梯门时门套是否有异响（判断是否与电梯轿厢干涉）。交付使用前，需告知用户日常维护注意事项（如避免硬物撞击、定期用中性清洁剂擦拭），尤其潍坊冬季供暖期，需提醒保持室内湿度（40%-60%），防止木质门套因干燥出现开裂。

　　After installation, maintenance and acceptance should cover both short-term and long-term usage needs. Within 24 hours after installation, avoid collisions and heavy pressure. Before the sealant is completely cured (usually 72 hours), keep it ventilated and dry to avoid damp environments affecting the adhesive effect. Key inspection points for acceptance: verticality (measurement error with a ruler ≤ 3mm), flatness (≤ 2mm), joint gap (≤ 0.5mm), and whether there is any abnormal noise from the door frame when opening the elevator door (to determine whether it interferes with the elevator car). Before delivery for use, users should be informed of daily maintenance precautions (such as avoiding hard object impact and regularly wiping with neutral cleaning agents), especially during the winter heating period in Weifang, it is necessary to remind to maintain indoor humidity (40% -60%) to prevent wooden door frames from cracking due to dryness.
