Anchor-bolt layout (count ↔ spacing)

Q: "Why can input and actual spacing differ?"

"With Equal spacing, the actual interval is recalculated so the effective length is filled exactly."

Q: "What does the fit-priority badge mean?"

"The requested count did not fit the fixed-spacing rule, so it was adjusted automatically to a value that fits."

Q: "What does the centered-symmetry quick action do?"

"It sets both offsets to the larger value and switches the layout rule to Centered."

Q: "Can I use this output as a structural approval?"

"No. This tool supports placement only; it does not perform structural verification."

Important notice

This tool supports placement only. It does not cover strength, pullout, anchorage length, or concrete design checks.
For final decisions, follow applicable standards, site procedures, and supervisor instructions.

How to use the tool

Choose count → spacing or spacing → count.
Enter total length L and left/right offsets, then review effective length Le.
Select equal, centered, or flush layout and use quick actions when needed.
Review the summary, schematic, and coordinate table, then export TSV or CSV.

Examples

Count → Spacing

Input

L=6000, leftOffset=100, rightOffset=100, n=5

Output

Le=5800, pitch=1450, x=[100,1550,3000,4450,5900]

Spacing → Count (Centered + Ceil)

Input

L=6000, leftOffset=100, rightOffset=100, pitch=450, rounding=ceil

Output

nCandidate=14 does not fit, so it is auto-adjusted to n=13

Layout formulas

Le = L − leftOffset − rightOffset
n2p: actual spacing = Le / (n − 1)
p2n: candidate count = floor / ceil / round(Le / pitch) + 1
equal: actual spacing = Le / (n − 1), remainder = 0
centered: start = leftOffset + remainder / 2
flush-right: start = leftOffset + remainder

Frequently asked questions

Why can input and actual spacing differ?

With Equal spacing, the actual interval is recalculated so the effective length is filled exactly.

What does the fit-priority badge mean?

The requested count did not fit the fixed-spacing rule, so it was adjusted automatically to a value that fits.

What does the centered-symmetry quick action do?

It sets both offsets to the larger value and switches the layout rule to Centered.

Can I use this output as a structural approval?

No. This tool supports placement only; it does not perform structural verification.
