使用说明与常见问题How-to & FAQ

「混凝土方量计算器（板、柱、数量、损耗、袋数）」是什么？What is the Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags) tool?

计算浇筑所需混凝土：长方形板/基础（长 × 宽 × 厚）或圆柱（直径 × 高），可填数量和损耗率，结果给出立方米、立方码、立方英尺，以及预拌干混料袋数（25 kg、40 kg、60 lb、80 lb）。本地处理。Concrete needed for a rectangular slab or footing (length × width × thickness) or a round column (diameter × height), with quantity and waste allowance. Results in cubic metres, cubic yards and cubic feet, plus premix bag counts (25 kg, 40 kg, 60 lb, 80 lb). Processed locally.

如何使用「混凝土方量计算器（板、柱、数量、损耗、袋数）」？How do I use the Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags) tool?

在「混凝土方量计算器（板、柱、数量、损耗、袋数）」中，填写「形状」、「尺寸单位」、「长」、「宽」、「厚度」等参数，结果会随输入实时计算并显示在下方。In the Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags): Fill in "Shape", "Units", "Length", "Width", "Thickness"; results are recalculated instantly as you type.

损耗率取多少合适？How much waste should I allow?

一般取 5–10%：模板变形、地面不平和撒漏都会多用料。地基不平整或第一次施工时取 10%。Usually 5–10%: formwork movement, uneven ground and spills all use extra. Use 10% for uneven subgrades or a first pour.

10 cm 厚的板每平方米要多少混凝土？How much concrete per square metre for a 10 cm slab?

0.1 m³（1 m × 1 m × 0.1 m）。20 m² 的 10 cm 板约 2 m³，加 5% 损耗为 2.1 m³。0.1 m³ (1 m × 1 m × 0.1 m). A 20 m² slab 10 cm thick needs about 2 m³, or 2.1 m³ with 5% waste.

能举个计算实例吗？Can you show a worked example?

例如在「混凝土方量计算器（板、柱、数量、损耗、袋数）」中填 形状 = 板/基础，尺寸单位 = 米 m，长 = 5，宽 = 4，厚度 = 0.1，数量 = 1，结果区显示：所需混凝土：2.1 m³；立方码：2.747 yd³；立方英尺：74.16 ft³；净体积（不含损耗）：2 m³；25 kg 袋：175；40 kg 袋：111；60 lb 袋：166；80 lb 袋：124；ℹ 袋数按常见出方量估算：25 kg ≈ 0.012 m³、40 kg ≈ 0.019 m³、60 lb ≈ 0.45 ft³、80 lb ≈ 0.6 ft³；大于约 1 m³…For example, entering Shape = Slab or footing, Length = 5, Width = 4, Thickness = 0.1, Quantity = 1, Waste (%) = 5 in the Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags) gives: Concrete needed: 2.1 m³; Cubic yards: 2.747 yd³; Cubic feet: 74.16 ft³; Net volume (no waste): 2 m³; 25 kg bags: 175; 40 kg bags: 111; 60 lb bags: 166; 80 lb bags: 124; ℹ bag counts use typical yields: 25 kg ≈ 0.012 m³, 40 kg ≈ 0.019 m³, 60 lb ≈ 0.45 ft³, 80…

哪些输入会被检查？Which inputs are validated?

「混凝土方量计算器（板、柱、数量、损耗、袋数）」会检查这些输入——「长」：须大于 0且不大于 1,000,000；「宽」：须大于 0且不大于 1,000,000；「厚度」：须大于 0且不大于 1,000,000；「直径」：须大于 0且不大于 1,000,000；「高」：须大于 0且不大于 1,000,000；「数量」：必须填写，须为不小于 1且不大于 1,000,000的整数；「损耗（%）」：必须填写，须不小于 0且不大于 50；绝对值超过 10¹⁵ 的数也会被拒绝。不符合时结果区显示具体提示，不会给出数字。The Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags) checks its inputs — "Length": must be more than 0 and at most 1,000,000; "Width": must be more than 0 and at most 1,000,000; "Thickness": must be more than 0 and at most 1,000,000; "Diameter": must be more than 0 and at most 1,000,000; "Height": must be more than 0 and at most 1,000,000; "Quantity": required, must be at least 1 and at most 1,000,000 (a whole number); "Waste (%)": required, must be at least 0 and at most 50; numbers above 10¹⁵ in absolute value are rejected too. When a value fails, the result area names the problem instead of showing a number.

有哪些选项可以调整？What options can I adjust?

「混凝土方量计算器（板、柱、数量、损耗、袋数）」的设置：「形状」可选 板/基础、圆柱（默认 板/基础）；「尺寸单位」可选 米 m、厘米、英尺、英寸（默认 米 m）；「长」默认 5；「宽」默认 4；「厚度」默认 0.1；「直径」默认 0.3；「高」默认 3；「数量」默认 1；「损耗（%）」默认 5。每次生成结果都按当前设置处理。Settings in the Concrete Volume Calculator (Slab, Column, Quantity, Waste, Bags) — "Shape": Slab or footing, Round column (default Slab or footing); "Units": 4 choices; "Length" default 5; "Width" default 4; "Thickness" default 0.1; "Diameter" default 0.3; "Height" default 3; "Quantity" default 1; "Waste (%)" default 5. The result always uses the current settings.
