濰坊電梯門套安裝需兼顧安全性、美觀性與耐用性，受當地氣候（夏季多雨、冬季寒冷）和建筑風格影響，安裝過程需注重細節把控，從前期準備到后期驗收，每個環節的規范操作都直接影響最終效果與使用安全，尤其需適應本地環境特點，確保門套長期穩定使用。

　　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.

　　安裝前的測量與材料檢查是基礎，直接決定安裝精度。需使用激光水平儀和卷尺精確測量電梯洞口的寬度、高度及垂直度，誤差超過 5mm 需提前處理（如鑿平墻體或填充修補），避免門套安裝后出現縫隙或傾斜。濰坊地區建筑墻體多為混凝土或加氣塊，需根據墻體材質選擇適配的固定件（混凝土墻體用膨脹螺栓，加氣塊墻體用專用尼龍錨栓），防止固定不牢導致后期松動。材料檢查重點關注門套線條的平整度（彎曲度不超過 2mm/m）、表面光潔度（無劃痕、凹陷），以及配套膠水的耐候性（需適應 - 10℃至 40℃溫差），避免因材料質量問題影響安裝效果和使用壽命。

　　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.

　　基層處理需適應濰坊氣候特點，增強防潮與穩固性。電梯井口周邊墻體常因冷凝水出現返潮，安裝前需清理基層浮灰、油污，用防水砂漿抹平墻面，陰陽角做圓弧處理，干燥后涂刷防潮底漆，防止潮氣滲透導致門套變形（尤其木質或復合材質門套）。對于老舊小區改造項目，需檢查原洞口是否有裂縫、空鼓，空鼓面積超過 10% 需鏟除重做，確保基層承載力達標。若洞口與門套間隙過大（超過 3cm），需用細石混凝土填充而非發泡劑，增強結構穩定性，抵御濰坊春季多風天氣可能帶來的振動影響。

　　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.

　　安裝固定過程注重垂直度與牢固性，避免安全隱患。門套線條拼接處需預留 1-2mm 伸縮縫（應對溫度變化引起的熱脹冷縮），拼接角度保持 90°，用角尺實時校準。固定時遵循 “先上后下、先內后外” 原則，頂部線條用 2-3 個固定點，兩側線條每 50cm 設一個固定點，確保受力均勻。膨脹螺栓埋入墻體深度不小于 5cm，擰緊后做防松處理（加彈簧墊圈），防止長期使用后松動。對于不銹鋼等金屬門套，需注意與墻體間的絕緣處理（墊橡膠墊片），避免電化學腐蝕（濰坊空氣濕度較高時更易發生），同時預留 3-5mm 安裝間隙，方便后期調整。

　　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.

　　密封與收口處理影響美觀與防潮性能，細節決定品質。門套與墻體間隙用中性硅酮密封膠填充（避免酸性膠腐蝕金屬件），膠線寬度控制在 3-5mm，表面用工具壓平刮光，確保無氣泡、無斷縫。木質門套底部需高出地面 5-10mm，防止拖地時污水浸泡；石材門套與地面接觸處做斜坡處理，引導水流遠離門套。濰坊部分地區有地暖，安裝時需確認門套底部與地暖管道的安全距離（不小于 10cm），避免高溫導致材質變形。收口線條對接處需齊平，誤差不超過 0.5mm，用同色密封膠填補微小縫隙，提升整體美觀度。

　　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.

　　安裝后養護與驗收需覆蓋短期與長期使用需求。安裝完成 24 小時內避免碰撞、重壓，密封膠完全固化前（通常 72 小時）保持通風干燥，避免潮濕環境影響膠黏效果。驗收重點檢查：垂直度（用靠尺測量誤差≤3mm）、平整度（≤2mm）、拼接處縫隙（≤0.5mm），以及開啟電梯門時門套是否有異響（判斷是否與電梯轎廂干涉）。交付使用前，需告知用戶日常維護注意事項（如避免硬物撞擊、定期用中性清潔劑擦拭），尤其濰坊冬季供暖期，需提醒保持室內濕度（40%-60%），防止木質門套因干燥出現開裂。

　　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.
