201安徽不锈钢包口安装费计算

　　201 Anhui stainless steel package installation fee calculation

　　一 计量口径与工程量计算

　　Measurement caliber and engineering quantity calculation

　　计量单位以“米（m）”为主，按包口“中心线展开长度”计量；装饰线条类通常按米计价与计量。若采用金属板折边做包口，也可按“平方米（m?）”计量，再折算为米用于安装费核算。

　　The unit of measurement is mainly "meter (m)", measured according to the "centerline unfolded length" of the package; Decorative lines are usually priced and measured in meters. If metal sheet folding is used as the packaging, it can also be measured in square meters (m?) and converted into meters for installation cost accounting.

　　计算规则

　　calculation rule

　　直线段：按实际净长计。

　　Straight line segment: calculated based on actual net length.

　　阳角/阴角：按“外包线长度”计（含包角展开），不重复计量直线段。

　　Positive/negative angle: calculated based on the "length of the outer edge" (including the unfolded edge), without repeating the measurement of straight line segments.

　　门套/门楣等：按可见外轮廓展开长度计。

　　Door frame/lintel, etc.: Calculated based on the visible outer contour unfolded length.

　　损耗：安装费通常不计损耗，损耗体现在材料采购（常见按**3%–5%**计）。

　　Loss: Installation fees usually do not include loss, which is reflected in material procurement (usually calculated at * * 3% -5% * *).

　　示例

　　example

　　单开门包口：2（侧边）+（门楣长度）+（底边长度）= 总安装米数。

　　Single door package: 2 (side)+(lintel length)+(bottom edge length)=total installation meters.

　　阳角包边：两面外包线长度之和（含阳角折弯展开）。

　　External corner edge wrapping: the sum of the lengths of the external wrapping lines on both sides (including the bending and unfolding of the external corners).

　　以上口径与计量做法与行业常见规则一致：装饰线按米计算，包边条在工厂可折弯加工，现场以米为安装计量单位。

　　The above caliber and measurement methods are consistent with common industry rules: decorative lines are calculated in meters, edge banding can be bent and processed in the factory, and on-site installation measurement units are in meters.

　　二 单价构成与参考区间

　　Two unit price composition and reference range

　　安装费通常拆分为：

　　The installation fee is usually divided into:

　　基层处理/找平（如需）

　　Grassroots treatment/leveling (if necessary)

　　定位放线、试拼、切割下料

　　Positioning and laying out, trial assembly, cutting and cutting of materials

　　粘贴/铆接/焊接、打磨、清洁

　　Paste/rivet/weld, polish, clean

　　成品保护、垃圾清运、成品验收

　　Finished product protection, garbage disposal, and finished product acceptance

　　市场常见参考价（仅指“安装费”，不含材料、辅材、机械与成品保护等）

　　Common reference prices in the market (only referring to "installation fees", excluding materials, auxiliary materials, machinery, and finished product protection, etc.)

　　常规室内直线包边：5–8 元/米（含粘接/打胶、常规切割与收口）

　　Regular indoor straight edge wrapping: 5-8 yuan/meter (including bonding/gluing, regular cutting and closing)

　　复杂部位（如大量阳角、弧线、灯槽、与石材/金属/玻璃多材质交接）：在上述基础上上浮 20%–50%

　　Complex parts (such as a large number of external corners, curved lines, lamp troughs, and intersections with multiple materials such as stone/metal/glass): increase by 20% -50% on the above basis

　　基层处理（如需）：

　　Grassroots treatment (if necessary):

　　砖墙基层：约 3.7 元/米·单/双层50内

　　Brick wall base: about 3.7 yuan/meter, single/double layer within 50 yuan

　　夹板基层：约 2.5 元/米·单/双层50内

　　Plywood base layer: about 2.5 yuan/meter, single/double layer within 50 yuan

　　每增加50 mm基层厚度：另加约 2 元/米

　　For every 50mm increase in base thickness, an additional fee of approximately 2 yuan per meter will be charged

　　计价口径：按“安装延长米”计，不随板宽变化（10 cm 与 30 cm 包边安装工序差异已体现在单价中）。

　　Pricing caliber: Calculated based on "installation extension meters" and does not vary with the width of the board (the difference between the 10 cm and 30 cm edge wrapping installation processes has been reflected in the unit price).

　　以上区间与做法要点来源于行业报价与节点做法资料，适用于201不锈钢包口的常见室内装饰场景。

　　The above intervals and practice points are sourced from industry quotations and node practice data, and are applicable to common interior decoration scenarios with 201 stainless steel cladding.

　　三 快速报价公式与示例

　　Three Quick Quotation Formulas and Examples

　　公式

　　formula

　　安装费合计 = Σ（各段“中心线展开长度” × 对应安装单价） + 基层处理费 + 复杂节点上浮 + 其他费用（成品保护、清运等）

　　Total installation cost=∑ (length of each section's "centerline expansion" multiplied by the corresponding installation unit price)+base treatment fee+complex node uplift+other costs (finished product protection, cleaning, etc.)

　　示例（单开门包口，201不锈钢，板宽100 mm，室内直线）

　　Example (Single door package, 201 stainless steel, plate width 100mm, indoor straight line)

　　假设：侧边各2.10 m，门楣1.00 m，底边1.00 m，合计安装米数 = 6.20 m

　　Assumption: 2.10m on each side, 1.00m on the lintel, and 1.00m on the bottom edge, with a total installation distance of 6.20m

　　安装单价：6.0 元/米（取5–8元/米的中值）

　　Installation unit price: 6.0 yuan/meter (taking the median of 5-8 yuan/meter)

　　安装费小计：6.20 × 6.0 = 37.20 元

　　Subtotal installation fee: 6.20 × 6.0=37.20 yuan

　　如需砖墙基层（单层50内）：3.7 × 6.20 = 22.94 元

　　If you need a brick wall base (within 50 units per layer): 3.7 × 6.20=22.94 yuan

　　合计：约 60.14 元（未含辅材如结构胶、保护、清运等，若含按合同口径另计）

　　Total: Approximately 60.14 yuan (excluding auxiliary materials such as structural adhesive, protection, and transportation, if included, it will be calculated separately according to the contract scope)

　　该示例仅演示“按米计量、分部分项计价”的方法，复杂节点与基层条件按实际调整。

　　This example only demonstrates the method of "measuring by meter and pricing by sub item", and adjusts complex nodes and grassroots conditions according to actual conditions.

　　四 影响价格的关键因素与管控要点

　　Four key factors affecting prices and key control points

　　影响因素

　　influencing factors

　　基层状况与找平难度（砖墙、夹板、是否需加衬板/龙骨）

　　Grassroots condition and leveling difficulty (brick walls, plywood, whether to add lining boards/keels)

　　线条宽度与折弯数量（阳角、阴角、弧线、多段拼接）

　　Line width and number of bends (male angle, female angle, arc, multi segment splicing)

　　工艺方式（胶粘、自攻螺丝/铆接、焊接、背栓/卡槽等）

　　Process methods (adhesive, self tapping screws/riveting, welding, back bolt/slot, etc.)

　　收口与细节（与石材/木作/玻璃/金属交接、缝隙控制、打磨抛光要求）

　　Closing and details (requirements for handover with stone/wood/glass/metal, gap control, and polishing)

　　现场条件（高空、狭小空间、成品保护难度、交叉作业）

　　Site conditions (high altitude, narrow space, difficulty in protecting finished products, cross operation)

　　质量要求（直线度、接缝顺直、表面洁净度、返工风险）

　　Quality requirements (straightness, straight seams, surface cleanliness, rework risk)

　　管控要点

　　Key Control Points

　　合同中明确：计量口径（米/平方米）、单价包含/不包含的工作内容与辅材、基层处理责任与计价、复杂节点上浮比例、验收标准与返工条款。

　　The contract specifies: measurement caliber (meters/square meter), work content and auxiliary materials included/excluded in the unit price, grassroots processing responsibilities and pricing, floating ratio of complex nodes, acceptance standards and rework clauses.

　　现场先试拼、统一下料尺寸，减少拼缝与打磨返工。

　　On site trial assembly and uniform cutting size to reduce joint and polishing rework.

　　对弧形/大尺寸包边，优先工厂折弯，现场仅做定位与固定，降低误差与工时。

　　For curved/large-sized edging, priority should be given to factory bending, and only positioning and fixing should be done on site to reduce errors and labor hours.

　　上述做法与注意点在行业节点与报价说明中被反复强调，尤其是“先打基底（最好有衬板）、工厂折弯、现场安装”的流程与“计价按米、复杂上浮”的原则。

　　The above methods and precautions are repeatedly emphasized in industry nodes and quotation explanations, especially the process of "laying the foundation first (preferably with lining plates), factory bending, and on-site installation" and the principle of "pricing by meter and complex upward adjustment".
