概述
尖头密拼围栏(Stockade Fence)借鉴经典要塞木栅栏结构,立板紧贴且顶端切尖,具备良好的隐私遮蔽与防护功能。
既可在现场逐根逐块手工拼装,也可采购预制的8英尺成型木栅栏单元快速吊装在立柱之间。
假设前提
- Pickets are 1x4 or 1x6 pointed-top stockade boards installed with zero gap.
- Standard height is 6 feet with 3 horizontal 2x4 support rails per post bay.
- Post spacing is set to 8 feet on center, with 4x4 or 6x6 ground-contact posts.
- Material counts include a 10 percent contingency for trimming, split boards, and leveling cuts.
常见错误
- 将尖头朝下安装或顶端高低不齐形成锯齿状破损外观。
- 采用过薄的横梁,在沉重密拼木料自重下发生永久性下坠弯曲。
- 将木板底部直接杵入松软潮湿泥土加速烂根。
- 未使用拉线校准立柱垂直度,导致整面围墙产生歪扭。
围栏计算公式
和计算器相同的数学,用大白话写出来。没有黑箱。
-
跨数
sections = max(ceil(effective run / post spacing), 1)
-
立柱数
posts = (sections + 1) along the run, minus named corner and end posts already placed, plus 2 gate posts per gate
-
有效长度
effective run = total length - sum of gate widths
-
横梁数
total rails = sections x rails per section
-
板条数
pickets = ceil(run in inches / (picket width + gap)); total = ceil(raw x (1 + waste %))
-
交错叠放式间距
pitch = picket width - 1 inch overlap
-
围栏板数
full panels = floor(run / panel width); add 1 cut panel if the remainder is over 0.01 ft; total = ceil(raw x (1 + waste %))
-
混凝土体积
per-hole = pi x (diameter / 2)^2 x depth; total = per-hole x posts; bags = ceil(total / bag yield)
-
坡度调整后长度
slope run = effective run / cos(atan(slope % / 100)); shown alongside, counts use the flat run
-
成本
materials = (posts x post price + rails x rail price + infill x unit price + 60 lb bags x bag price) x regional multiplier; labor = effective run x labor per ft x terrain multiplier x regional multiplier; installed total = materials + gate hardware + removal + permit + labor

A stockade fence sets closely spaced vertical pickets with pointed tops, built with zero gap for complete visual privacy, a style that traces back to historic defensive fortifications and today reads as a solid, clean-lined residential fence. In material terms it is close to a butted privacy fence: same zero-gap picket formula, same post and rail structure, with the pointed top and typically a 6 foot height as the defining details rather than anything that changes the underlying take-off.
Spruce, white pine and pressure-treated southern yellow pine are the most common stockade materials, chosen mainly for affordability and how easily they mill into pointed tips. Pressure-treated pine is the budget-friendly default for ground-contact posts on a stockade build, while cedar is the step up for anyone who wants the natural rot resistance and tighter grain without the chemical treatment.
Because stockade is a solid, zero-gap fence, it catches wind the way any tall privacy style does, which is why 3 horizontal rails per section is standard at 6 feet and tighter post spacing, commonly 6 feet rather than 8, is worth considering in open or windy sites. The fence rail calculator and fence post calculator are the places to fine-tune both numbers independently of the picket style, since rail and post counts here follow the same height-based formulas as every other wood style on this site.
Stockade differs from an open picket fence mainly in height and gap: picket fencing runs shorter with a visible gap for a decorative boundary look, while stockade runs taller and fully closed for privacy and a more defensive-looking line. How to install a wood privacy fence and the wood fence installation guide cover the build sequence, how many pickets for 100 feet of fence covers the zero-gap picket math stockade shares with privacy fencing, and the fence materials guide compares stockade's common species against the others covered on the wood fence calculators hub.
Pre-assembled stockade panels install faster than building the fence picket by picket on site, but stick-building allows the fence to be racked smoothly to follow sloped terrain without the stepped gaps that pre-made panels can leave on uneven ground. That tradeoff between installation speed and how well the fence follows the grade is worth weighing against the property's actual terrain before choosing a method, since it does not show up in the material count itself.
Because the pointed pickets run with zero gap and sit flush with their neighbors, any misalignment along the post string line shows up as a visible zigzag across the whole run, more so than on a style with a gap that can hide minor variation. In windy areas, a solid stockade fence catches wind load the same way a solid privacy fence does, which is why tighter post spacing and larger corner posts are worth considering on an exposed site rather than defaulting to the widest spacing the style allows.
Stockade fencing is also sometimes built with a scalloped top instead of individually pointed pickets, where the tops are cut in a shallow curve across several boards rather than each picket ending in its own point. That variation changes the top profile and the cutting labor involved but not the underlying picket, rail or post counts, which still follow the same zero-gap formula this calculator uses.
Because the style reads as a solid, uniform wall once built, small inconsistencies in picket height along the top are more visible on stockade than on a style with varied top profiles or a visible gap that already breaks up the sightline, which is part of why careful layout and consistent picket length matter more here than on some other wood styles.
The pointed top itself is more than decorative: the angled cut sheds rainwater off the end grain rather than letting it pool on a flat top, which is one of the practical reasons the style persisted long after its original defensive purpose became irrelevant. A flat-top picket on the same fence would be more exposed to standing moisture at the most vulnerable part of the board, the end grain.
A consistent picket length cut before installation, rather than trimming each picket to height after it is nailed up, is the more reliable way to keep the pointed tops level across a long stockade run, since on-site trimming compounds small errors from post to post.
Gate openings on a stockade run are handled the same way as on any other zero-gap wood style: the gate width comes out of the run before the picket count is computed, and two gate posts plus a hardware set are added on top of the line and corner posts the rest of the run needs. Because stockade pickets are cut tight with no gap, a gate opening that is measured even slightly wrong tends to show up as a visible mismatch in picket alignment on either side of the gate, more so than it would on a style with some gap to absorb a small error.
常见问题
木板顶部的尖头有什么实际作用?
除了具备防攀爬警示作用外,倾斜切削的尖顶能迅速排走雨水,减少端头木纹积水腐朽。
买现成单元板好还是单板现场拼装好?
现成单元板吊装速度快;逐根拼装则能平滑顺应地面的自然坡度,避免底部留出悬空缺口。
一块8英尺单元板包含多少根板条?
使用1x4板(实宽3.5英寸)约27至28根;使用1x6板(实宽5.5英寸)约17至18根。
实心密拼围栏在强风中安全吗?
实心围栏阻风面积大。在大风开阔地区,建议将立柱间距缩窄至6英尺并加深地基混凝土。
每根立柱孔需要几袋混凝土?
直径10英寸、深度24英寸的标准立柱孔,通常需消耗2至3袋60磅装干拌混凝土。
密拼围栏通常选用什么树种?
云杉、辐射松和加压黄松最为常见,易于机器裁切且性价比较高。
板条底部距离地面多少公分?
离地保持至少2英寸(约5厘米),避免雨水飞溅与土壤泥泞导致下缘吸湿霉烂。
密拼围栏需要多久维护一次?
建议每2至3年喷涂或滚涂一次半透明渗透型保护漆,防止木质干裂。
