每平方米需要多少块砖？

含灰缝时模数砖每平方米约 74 块。queen 规格约 62 块，king 约 50 块，utility 约 32 块。

标准砖的尺寸是多少？

模数砖名义为 20 × 6.8 × 10 厘米，实测 19.4 × 5.7 × 9.2。差值就是 1 厘米灰缝，所以估算用名义尺寸。

砌砖需要多少砂浆？

按 1 厘米灰缝，每 1,000 块模数砖约需七袋 32 公斤装。砖的用量是砌块的两倍以上，因为灰缝多得多。

砖饰面和实心砖墙有什么区别？

饰面是单层非承重砖，通过拉结件固定在框架墙上，后面留排水空腔。现代住宅的砖几乎都是饰面做法。

砖墙为什么要留排水孔？

因为饰面墙的设计就是让水进入再排出。空腔底部的排水孔就是出口，用砂浆堵死会把墙变成蓄水陷阱。

砖块计算器

按砖块规格计算墙体或饰面所需砖数，并给出砂浆袋数，同时扣除门窗洞口。

公式

砖数 = 净面积 × 每平方英尺砖数 × (1 + 损耗)

参考资料

Measure what the tool asks for
This calculator works from 墙体长度 in ft, 墙体高度 in ft and 门窗面积 in ft². Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
砖数 = 净面积 × 每平方英尺砖数 × (1 + 损耗) Every figure on the page comes out of that one expression, so you can check it by hand.
Why it adds 10% waste
10% 用于破损、洞口切割以及为混色而必需的挑选。
Choosing a 砖块规格
提示：模数砖是美国标准。queen 和 king 规格更高，每块覆盖墙面更多，砌筑速度也更快。
Where the numbers come from
The constants are taken from Brick Industry Association — Technical Notes on Brick Construction and ASTM C216 — Standard Specification for Facing Brick, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

常见问题

用墙面面积乘以所选规格的每平方英尺砖数，再加损耗。6 × 2.4 米的模数砖墙约需 1,098 块。
