CBQGT Column Base

CBQGT

On This Page

This product is only available in Canada

The CBQGT uses Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws, which allow for fast installation, reduced reveal, high capacity and provide a greater net section area of the column compared to bolts.

Material

  • See table

Finish

  • Simpson Strong-Tie® gray paint, available in HDG

Installation

  • Use all specified fasteners; see General Notes.
  • Install 1/4" x 2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column base. (Lag screws will not achieve the same load.)
  • Minimum 3" side cover on concrete is required.
  • Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non-top-supported installations (such as fences or unbraced carports).

Options

  • Other sizes available. Check with Simpson Strong‐Tie for details.

Load Tables

  1. Factored uplift resistances have been increased 15% for earthquake or wind loading, with no further increase allowed; reduce where other loads govern.
  2. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the tables reflect installation into the wide face.
  3. Designer is responsible for concrete design.
  4. Factored resistances shown assume dry service condition (KSF = 1.00). Multiply table values by 0.67 under wet service conditions.
  5. Minimum f'c shall be 20 MPa.
