「砖块用量计算器」是什么？What is the Brick Calculator tool?
按墙面长度、高度、门窗洞口面积、砖块尺寸和灰缝厚度计算需要多少块砖，内置美国标准砖、英国砖和中国标准砖（240×115×53 mm）尺寸，可加损耗。Find how many bricks a wall needs from its length, height, openings, brick size and mortar joint, with US modular, UK standard and Chinese standard (240×115×53 mm) bricks and a waste allowance.
如何使用「砖块用量计算器」？How do I use the Brick Calculator tool?
在「砖块用量计算器」中，填写「单位制」、「墙长（英尺/米）」、「墙高（英尺/米）」、「门窗洞口面积（平方英尺/m²）」、「砖块」等参数，结果会随输入实时计算并显示在下方。In the Brick Calculator: Fill in "Units", "Wall length (ft / m)", "Wall height (ft / m)", "Openings area (ft² / m²)", "Brick"; results are recalculated instantly as you type.
每平方米要多少块砖？How many bricks per square metre?
每平方米块数 = 1 ÷ [(砖长 + 灰缝) × (砖高 + 灰缝)]。10 mm 灰缝时，中国标准砖单层墙约 63.5 块/m²，英国砖约 59 块/m²，美国模数砖约 73 块/m²（约 6.8 块/ft²）。Bricks per m² = 1 ÷ [(length + joint) × (height + joint)]. With 10 mm joints that is about 63.5/m² for Chinese standard brick, 59 for UK brick and 73 for US modular (about 6.8/ft²) in a single leaf.
双层墙怎么算？What about thicker walls?
“双层”按两层顺砌（如中国的 240 mm 一砖墙或英国双层墙）计算，砖数翻倍；不同砌法（如一顺一丁）用量略有差异。Double leaf counts two layers of stretchers (such as a Chinese 240 mm wall or a UK double-skin wall), doubling the bricks; bonds like English bond use slightly different counts.
砖块尺寸和损耗的依据？Where do the brick sizes and waste come from?
中国标准砖 240×115×53 mm 来自 GB/T 5101-2017《烧结普通砖》；英国砖 215×102.5×65 mm 是 BS EN 771-1 常用工作尺寸；美国模数砖 7⅝×3⅝×2¼ in 见美国砖业协会（BIA）技术说明 10。默认损耗 5% 是常用估算值（示例值），切砖多或异形墙面应加大。Chinese standard brick 240×115×53 mm is from GB/T 5101-2017 (fired common bricks); UK 215×102.5×65 mm is the usual BS EN 771-1 work size; US modular 7⅝×3⅝×2¼ in is per the Brick Industry Association Technical Note 10. The 5% waste default is a common estimating value (example default); allow more for lots of cutting or irregular walls.
