Base fittings for structural support systems and framework foundations.
Structure Fittings Base Overview
The base fitting serves as the anchoring point for vertical structural tubes in glass support systems. Designed for foundation mounting, these base fittings include pre-drilled holes to accommodate foundation bolts and secure the support framework to floors or base slabs. They allow the vertical tubes to be fixed rigidly at their bottom end, transferring the full column load to the structure beneath. By utilizing these dedicated base fittings rather than generic flanges, the structural system ensures precise alignment, rigidity, and ease of leveling during installation. The presence of standard base models (e.g. BS25, BS30, BS40, BS50) simplifies component selection and integration into the broader modular framing system.

**Function & Interface**
– Designed to interface with the matching tube external diameter to receive the vertical tube
– Pre-drilled for foundation bolts to anchor the column base to concrete or support slabs
– Height (H) ensures correct elevation above foundation for leveling and grout clearance
– PCD (pitch circle diameter) corresponds to the spacing of bolt holes to match foundation layout
**Installation & Structural Considerations**
– The vertical tube must be fully seated into the base fitting and aligned before final tightening
– The base must be anchored to a structurally rigid substrate to prevent deflection or movement
– Grouting under and around the base fitting is recommended to distribute load and maintain levelness
– In cases of heavy loads or lateral forces, base fittings should be supplemented with lateral bracing or tie-downs
– For corrosive or aggressive environments, stainless steel or coated base fittings should be selected to resist degradation
Applications
Base fittings find usage in all applications where vertical structural tubes must be rigidly anchored, including:
– Foundation mounting of glass column support frameworks
– Fixed support for pipelines or vessels where structural roughness or movement must be minimized
– Systems where precise leveling and structural stiffness at the base are essential
– Installations requiring robust base fixation in chemical, laboratory, or pilot plant environments
– Modular glass support frameworks that interface with building foundations or floor slabs
