如何使用「混凝土砌块计算器（墙体、门窗扣除、损耗）」？How do I use the Concrete Block Calculator (Wall, Openings, Waste) tool?
在「混凝土砌块计算器（墙体、门窗扣除、损耗）」中，填写「单位」、「墙长」、「墙高」、「门窗洞口总面积（m² 或 ft²）」、「砌块规格」等参数，结果会随输入实时计算并显示在下方。In the Concrete Block Calculator (Wall, Openings, Waste): Fill in "Units", "Wall length", "Wall height", "Openings total area (m² or ft²)", "Block size"; results are recalculated instantly as you type.
每平方米要多少块？How many blocks per square metre?
390 × 190 mm 的块加 10 mm 灰缝，模数为 400 × 200 mm，每平方米 12.5 块。美国 8 × 16 英寸标准块每平方英尺 1.125 块（每 100 ft² 约 113 块）。A 390 × 190 mm block with a 10 mm joint is a 400 × 200 mm module, so 12.5 per square metre. A US 8 × 16 in standard block is 1.125 per square foot, about 113 per 100 ft².
损耗取多少？How much waste should I allow?
常见为 5–10 %，切块多、转角多或运输破损风险高时取上限。5–10 % is typical; use the top end when there is a lot of cutting, many corners or a risk of breakage.
门窗怎么扣除？How are openings handled?
把所有门窗洞口的面积加起来填入，单位与墙面积一致。过梁、圈梁占用的部分请自行扣除。Add up the area of all doors and windows in the same units as the wall. Take off lintels and bond beams yourself.
能举个计算实例吗？Can you show a worked example?
例如在「混凝土砌块计算器（墙体、门窗扣除、损耗）」中填 单位 = 米，墙长 = 10，墙高 = 2，门窗洞口总面积（m² 或 ft²） = 0，砌块规格 = 390 × 190 mm，灰缝 10 mm，损耗 % = 0，结果区显示：净墙面积：20 m²；每平方米块数：12.5；需要砌块：250；含损耗订购：250；砌筑行数：10；ℹ 按“块 + 灰缝”的模数计算；转角、柱和半块未单独考虑。For example, entering Units = Metres, Wall length = 10, Wall height = 2, Openings total area (m² or ft²) = 0, Block size = 390 × 190 mm, 10 mm joint, Waste % = 0 in the Concrete Block Calculator (Wall, Openings, Waste) gives: Net wall area: 20 m²; Blocks per m²: 12.5; Blocks needed: 250; Order with waste: 250; Courses: 10; ℹ Uses the block plus joint module; corners, piers and half blocks are not counted separately.
哪些输入会被检查？Which inputs are validated?
「混凝土砌块计算器（墙体、门窗扣除、损耗）」会检查这些输入——「墙长」、「墙高」：必须填写，须大于 0；「门窗洞口总面积（m² 或 ft²）」：不能为负数；「自定义块长 mm」、「自定义块高 mm」：所选方式用到时必须填写，须大于 0；「自定义灰缝 mm」、「损耗 %」：可留空；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 Block Calculator (Wall, Openings, Waste) checks its inputs — "Wall length", "Wall height": required, must be greater than 0; "Openings total area (m² or ft²)": cannot be negative; "Custom block length mm", "Custom block height mm": required when the chosen option uses it, must be greater than 0; "Custom joint mm", "Waste %": optional; 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?
「混凝土砌块计算器（墙体、门窗扣除、损耗）」的设置：「单位」可选 米、英尺（默认 米）；「墙长」默认 10；「墙高」默认 2；「门窗洞口总面积（m² 或 ft²）」默认 0；「砌块规格」可选 390 × 190 mm，灰缝 10 mm、440 × 215 mm，灰缝 10 mm、8 × 16 英寸标准块 (7⅝ × 15⅝ + ⅜ 灰缝)、8 × 12 英寸、自定义（默认 390 × 190 mm，灰缝 10 mm）；「自定义块长 mm」默认 390；「自定义块高 mm」默认 190；「自定义灰缝 mm」默认 10；「损耗 %」默认 5。每次生成结果都按当前设置处理。Settings in the Concrete Block Calculator (Wall, Openings, Waste) — "Units": Metres, Feet (default Metres); "Wall length" default 10; "Wall height" default 2; "Openings total area (m² or ft²)" default 0; "Block size": 390 × 190 mm, 10 mm joint, 440 × 215 mm, 10 mm joint, 8 × 16 in standard block, 8 × 12 in, Custom (default 390 × 190 mm, 10 mm joint); "Custom block length mm" default 390; "Custom block height mm" default 190; "Custom joint mm" default 10; "Waste %" default 5. The result always uses the current…
