Double Stringer Staircase Detail Dwg

Zoom in on how the tread carrier is welded to the stringer face. Specify fillet weld sizes (typically 1/4" or 6mm minimum continuous welds). Structural Engineering & Material Specifications

: Usually angle irons or flanged plates that are welded or bolted to the stringers to hold the tread in place.

Indicate the path of travel and clear width between handrails. 3. Connection Details (Scale 1:2 or 1:5) double stringer staircase detail dwg

A professional CAD drawing for this type of staircase must include several critical views and technical specifications:

The DWG drawing includes the following views:

Use these standard layers for a professional CAD file: Zoom in on how the tread carrier is

You can build your own from scratch (using the steps above), but for production work, consider these sources:

When working with dimension lumber, one standard method is to notch the stair stringers and consider only the depth of wood beneath the tread/riser notches as effective in resisting the applied load. However, engineering judgment should be used in its implementation.

The is far more than a set of lines on a computer screen. It is a legal document, a fabrication instruction manual, and a safety certification rolled into one. Whether you are designing a grand helical staircase with double stringers or a simple back-of-house utility stair, the quality of your DWG determines the quality of the build.

While DWG is the industry standard for 2D shop drawings, the AEC industry is moving toward BIM (Building Information Modeling). When you create your double stringer detail:

Open-riser designs are highly popular for double stringers to maximize light filtration. Connections and Anchors

Draw the main section at 1:10 or 1:20. Use 1:2 or 1:5 for specific weld symbols and bolt placements.
