40 厘米中心距怎么快速估算？

把墙长（英尺）乘以 0.75 再加一。20 英尺的墙为 15 + 1 = 16 根。60 厘米中心距则乘以 0.5 再加一。

一个门洞要增加几根立柱？

基本情况是四根：两侧各一根主柱和一根承重短柱。过梁上方还要按墙体间距增加短柱，窗台下方同理。

主柱和短柱有什么区别？

主柱从下横梁通到上横梁，紧靠洞口。短柱较矮，贴着主柱承托过梁。两者缺一不可：主柱抗侧移，短柱传荷载。

一面墙需要几根横梁？

一根下横梁加两根上横梁是标准做法，即墙长的三倍线性长度。双层上横梁在转角和交接处搭接，把各面墙连成整体。

2.44 米高的墙用多长的立柱？

235 厘米的预裁立柱。加上 3.8 厘米下横梁和两根 3.8 厘米上横梁，正好 244 厘米——预裁立柱之所以是这个尺寸就是这个原因。

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 立柱中心距 in in. 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
标准立柱 = 向下取整(墙长 ÷ 间距) + 1 · 每个洞口 + 4 · 每个转角 + 2 Every figure on the page comes out of that one expression, so you can check it by hand.
Where the numbers come from
The constants are taken from IRC R602 — Wood wall framing and American Wood Council — Wood Frame Construction Manual, 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

用墙长除以间距再加一根收尾。6 米长的墙按 40 厘米中心距需要 16 根标准立柱，再加每个洞口四根、每个转角两根。
