🧱 铺路砖用量计算器Paver Calculator

使用说明与常见问题How-to & FAQ

「铺路砖用量计算器」是什么？What is the Paver Calculator tool?

按铺装面积、砖块尺寸、缝宽和损耗率计算需要多少块铺路砖，以及碎石垫层和找平砂的体积（立方码 / 立方米）。Work out how many pavers you need from the patio area, paver size, joint width and waste allowance, plus the volume of gravel base and bedding sand (cubic yards / cubic meters).

如何使用「铺路砖用量计算器」？How do I use the Paver Calculator tool?

在「铺路砖用量计算器」中，填写「单位」、「铺装长度（英尺 / 米）」、「铺装宽度（英尺 / 米）」、「砖长（英寸 / 厘米）」、「砖宽（英寸 / 厘米）」等参数，结果会随输入实时计算并显示在下方。In the Paver Calculator: Fill in "Units", "Area length (ft / m)", "Area width (ft / m)", "Paver length (in / cm)", "Paver width (in / cm)"; results are recalculated instantly as you type.

铺路砖数量怎么算？How is the number of pavers calculated?

块数 = 铺装面积 ÷ [(砖长 + 缝宽) × (砖宽 + 缝宽)]，再乘以 (1 + 损耗率) 并向上取整。切割边角、图案拼法越复杂，损耗率应越高，常见 5%–10%。Pavers = area ÷ [(length + joint) × (width + joint)], times (1 + waste) and rounded up. More cutting and complex patterns need more waste; 5%–10% is common.

垫层体积怎么算？How is the base volume calculated?

体积 = 面积 × 厚度。英制结果同时给出立方英尺和立方码（1 立方码 = 27 立方英尺）。压实后的碎石会比松散时少，购买时可多备一些。Volume = area × depth. Imperial results show cubic feet and cubic yards (1 cu yd = 27 cu ft). Gravel compacts, so buy a little extra.
