电梯门套作为电梯井道与建筑结构的衔接部件，其安装质量直接影响电梯运行安全与建筑美观。潍坊地区因气候特征与施工规范差异，门套安装检验需结合地域特性制定专项方案。本文从材料验收、安装精度、功能测试三大环节，详细阐述标准化检验流程。

　　As a connecting component between the elevator shaft and the building structure, the installation quality of the elevator door frame directly affects the safety of elevator operation and the aesthetics of the building. Due to differences in climate characteristics and construction standards in Weifang area, a special plan for door frame installation inspection needs to be developed based on regional characteristics. This article elaborates on the standardized inspection process from three major aspects: material acceptance, installation accuracy, and functional testing.

　　一、材料进场检验

　　1、 Material entry inspection

　　材质与规格核查

　　Material and specification verification

　　检查门套材质证书，确认不锈钢板厚度≥1.2mm，石材吸水率≤0.5%，复合材料防火等级达B1级。某项目因使用厚度不足的不锈钢门套，导致变形率超标，后更换为1.5mm厚板材后通过验收。

　　Check the material certificate of the door frame, confirm that the thickness of the stainless steel plate is ≥ 1.2mm, the water absorption rate of the stone is ≤ 0.5%, and the fire rating of the composite material reaches B1 level. A certain project had an excessive deformation rate due to the use of stainless steel door frames with insufficient thickness, which were later replaced with 1.5mm thick plates and passed the acceptance inspection.

　　核对门套尺寸与电梯井道预留洞口匹配度，宽度偏差需控制在±2mm以内，高度偏差≤3mm。

　　Check the matching degree between the size of the door frame and the reserved opening in the elevator shaft. The width deviation should be controlled within ± 2mm, and the height deviation should be ≤ 3mm.

　　外观质量检查

　　Appearance quality inspection

　　不锈钢门套表面应无划痕、凹坑，镜面抛光处理的光泽度≥600Gu。

　　The surface of the stainless steel door frame should be free of scratches and pits, and the glossiness of the mirror polishing treatment should be ≥ 600Gu.

　　石材门套需检查色差与裂纹，采用色差仪测量ΔE值≤1.5，敲击听声排查空鼓。

　　The stone door frame needs to be checked for color difference and cracks. A colorimeter should be used to measure the Δ E value ≤ 1.5, and knocking and listening should be used to check for hollowing.

　　二、安装过程检验

　　2、 Installation process inspection

　　基层处理验收

　　Grassroots treatment acceptance

　　确认井道墙体垂直度≤3mm/2m，平整度≤2mm，使用2米靠尺与塞尺检测。某老旧小区改造项目因墙体倾斜，导致门套安装后缝隙不均，后经凿平处理达标。

　　Confirm that the verticality of the shaft wall is ≤ 3mm/2m and the flatness is ≤ 2mm, and use a 2-meter ruler and a feeler gauge for inspection. The renovation project of an old residential area resulted in uneven gaps after the installation of door frames due to the inclined walls, which were later chiseled and leveled to meet the standards.

　　检查防潮层施工，确认聚乙烯薄膜搭接宽度≥100mm，胶粘剂涂抹均匀。

　　Check the construction of the moisture-proof layer, confirm that the overlap width of the polyethylene film is ≥ 100mm, and apply the adhesive evenly.

　　门套定位与固定

　　Door frame positioning and fixation

　　采用激光投线仪校准门套垂直度与水平度，偏差需≤1mm。某商业综合体项目因未使用激光定位，导致门套倾斜引发电梯门碰撞故障。

　　The verticality and levelness of the door frame are calibrated using a laser projector, with a deviation of ≤ 1mm. In a commercial complex project, the door frame tilted due to the lack of laser positioning, resulting in elevator door collision failure.

　　检验固定点间距，膨胀螺栓锚固深度≥50mm，焊接部位需做防锈处理。

　　Check the spacing between fixed points, anchor the expansion bolt to a depth of ≥ 50mm, and perform rust prevention treatment on the welding area.

　　接缝与收口处理

　　Seam and closing treatment

　　检查门套与墙面缝隙，填充发泡胶需密实无空洞，硅酮密封胶施打宽度≥8mm，表面光滑无流挂。

　　Check the gap between the door frame and the wall, fill the foam adhesive tightly without voids, apply silicone sealant with a width of ≥ 8mm, and ensure a smooth surface without sagging.

　　阴阳角拼接处需采用45°斜角对接，拼缝误差≤0.5mm。

　　The joint between the yin and yang corners should be connected at a 45 ° angle, with a joint error of ≤ 0.5mm.

　　三、功能与安全测试

　　3、 Functional and safety testing

　　开关门顺畅性测试

　　Smooth door opening and closing test

　　模拟电梯运行1000次，检查门套与轿门间隙是否恒定，间隙偏差≤2mm。某医院电梯因门套变形导致轿门卡阻，后增设限位装置解决。

　　Simulate elevator operation 1000 times, check whether the gap between the door frame and the car door is constant, with a gap deviation of ≤ 2mm. A hospital elevator had a door frame deformation causing the car door to jam, and later added a limit device to solve the problem.

　　测试门锁触点接触可靠性，确认门闭合时电阻≤0.1Ω。

　　Test the contact reliability of the door lock contacts and confirm that the resistance is ≤ 0.1 Ω when the door is closed.

　　抗冲击与耐候性验证

　　Impact resistance and weather resistance verification

　　对石材门套进行落球冲击试验，500g钢球1米高度自由落体，表面无裂纹。

　　Conduct a drop ball impact test on the stone door frame, with a 500g steel ball freely falling from a height of 1 meter and no cracks on the surface.

　　模拟潍坊夏季高温环境，将门套置于60℃恒温箱72小时，检查变形率≤0.2%。

　　Simulate the high temperature environment in Weifang during summer, place the door frame in a 60 ℃ constant temperature box for 72 hours, and check that the deformation rate is ≤ 0.2%.

　　防火与防烟性能检测

　　Fire and smoke prevention performance testing

　　核查防火门套燃烧性能报告，确认耐火极限≥1小时。

　　Verify the combustion performance report of the fireproof door frame and confirm that the fire resistance limit is ≥ 1 hour.

　　使用烟雾发生器测试门套密封性，烟雾渗透率≤5%。

　　Use a smoke generator to test the sealing of the door frame, with a smoke penetration rate of ≤ 5%.

　　四、验收文件与标识管理

　　4、 Acceptance documents and identification management

　　资料完整性审查

　　Data integrity review

　　收集材料合格证、检测报告、隐蔽工程记录，确保可追溯性。某安置房项目因缺失焊接记录，导致验收延期一周。

　　Collect material qualification certificates, testing reports, and concealed engineering records to ensure traceability. Due to the lack of welding records, the acceptance of a certain resettlement housing project was delayed by one week.

　　绘制门套安装位置图，标注关键尺寸与固定点坐标。

　　Draw a diagram of the installation position of the door frame, and mark the key dimensions and fixed point coordinates.

　　标识与维护指导

　　Identification and maintenance guidance

　　在门套内侧粘贴维护标签，注明清洁方法与禁令事项。

　　Stick maintenance labels on the inside of the door frame, indicating cleaning methods and prohibited items.

　　提供石材养护周期表，建议每半年进行结晶硬化处理。

　　Provide a stone maintenance cycle table, and it is recommended to perform crystallization hardening treatment every six months.

　　潍坊电梯门套安装检验需构建“材料-工艺-功能”三位一体管控体系。通过精准测量、严格测试、完整存档，可显著提升安装质量与长期可靠性。随着BIM技术的应用，未来的门套安装将实现数字化模拟与实时监控，为电梯工程安全提供更坚实的保障。

　　The installation inspection of elevator door frames in Weifang requires the establishment of a "material process function" integrated control system. By precise measurement, rigorous testing, and complete archiving, installation quality and long-term reliability can be significantly improved. With the application of BIM technology, the installation of door frames in the future will achieve digital simulation and real-time monitoring, providing a more solid guarantee for elevator engineering safety.
