The stringers are inset slightly from the edges of the treads, creating a floating effect while maintaining dual-beam rigidity. 2. Key Structural Components in a DWG Detail
In architectural and structural engineering, the staircase serves a dual purpose: it is a means of vertical circulation and a significant design element. Among the various structural configurations, the —characterized by two parallel structural supports running along the sides of the treads—offers a balanced solution that is structurally robust yet visually lighter than traditional bulkhead or concrete stairs.
Designing a double stringer system involves calculating specific geometry and load distributions:
S-STRS-CONN : Connection plates, bolts, and weld symbols (Continuous, Fine weight). double stringer staircase detail dwg
: Detail the specific timber members and connections, often including L-angle plates for fixing the stringers to the ground and landings. Adaptability
Detailed CAD files typically include these critical elements to ensure structural integrity and aesthetic alignment: Stringer Profiles : Often specifies steel sections like 100x100x9mm SHS (Square Hollow Section). Tread Details
Open look (no central stringer), suitable for widths up to ~1200 mm (48″). The stringers are inset slightly from the edges
Understanding the key components of a double stringer staircase is essential for preparing a comprehensive detail DWG:
A stringer is the primary structural support of a staircase—a diagonal framing member that runs along the length of the steps, holding the treads and risers in place and ensuring overall stability. Every staircase has at least one stringer, but most are built with two: a wall string fixed to the adjacent wall and a face string on the open, visible side.
A high-quality DWG detail is useless if it does not comply with local building regulations (such as IBC or IRC codes). Your CAD drawings should reflect the following standard benchmarks: Among the various structural configurations
Indicate the connection point of the balustrade to the stringers or treads. 2. Sectional Elevation (Side View)
Incorporating a double stringer system into your AutoCAD drafting workflow provides several distinct advantages:
Look for files providing a Plan View , Sectional Elevation , and Connection Details (top and bottom attachments).
