Extra Quality - Double Stringer Staircase Detail Dwg

Detail how the stringer attaches to the upper floor joist or concrete slab. Include weld symbols or bolt specifications (e.g., A325 structural bolts).

*Note: IBC requires 44 inches minimum width for occupant loads over 50, and 36 inches if the total occupant load is under 50. The 4-Inch Sphere Rule

The following design data is included in the DWG drawing:

: Shows how steps (e.g., 40mm wooden planks or steel plates) are mounted. Raised Treads

The core of a double stringer system consists of two primary load-bearing beams positioned on either side of the staircase or slightly offset toward the center. Common materials and profiles include: double stringer staircase detail dwg

: Includes floor-to-floor heights, riser/run calculations (typically 7" rise and 10-11" run), and total step count. Common Styles & Materials

: Open riser designs omit the vertical face between steps to maximize light filtration. Closed riser designs feature solid vertical plates for a traditional, secure enclosure. Core Components Included in a DWG Detail

A complete double stringer staircase package usually requires three specific view types within the DWG file. Detail how the stringer attaches to the upper

A complete, construction-ready DWG file must look beyond a basic side profile. To be highly functional for fabricators, ensure your file contains the following detailed views and callouts: A. Base Connection Detail (Footing)

: Often constructed from UPN profiles (channel) or IPE beams . Steel is preferred for its high strength-to-weight ratio, allowing for thinner structural members.

Always draft your staircase at actual size (1:1) in Model Space. Use Paper Space viewports to scale your detail sheets to standard printing sizes (such as 1-1/2" = 1'-0" or 3" = 1'-0").

Complete Guide to Double Stringer Staircase Details in CAD Double stringer staircases are a staple of modern architectural design. They offer an ideal balance of structural stability and minimalist aesthetics. For architects, engineers, and fabricators, having an accurate is essential for ensuring precise manufacturing and code compliance. The 4-Inch Sphere Rule The following design data

Before finalizing your DWG layouts, cross-reference your geometry with local building codes (such as the International Building Code [IBC] for commercial or International Residential Code [IRC] for residential structures):

: If creating a reusable asset, build the stringer detail as a dynamic block. This allows users to stretch the total rise and run while the risers and treads automatically recalculate and distribute uniformly.

Explicitly call out weld types (e.g., fillet welds with size symbols) and material grades (e.g., ASTM A36 Steel). 5. Conclusion
