CCQ/ECCQ Column Caps

CCQ/ECCQ

On This Page

Column caps provide a strong connection for column-beam combinations. This design uses Strong-Drive® SDS Heavy-Duty Connector screws to provide faster installation and provides a greater net section area of the column compared to bolts. The SDS screws provide for a lower profile compared to standard through bolts.

Material

  • CCQ3, ECCQ3, CCQ4, CCQ4.62, ECCQ4, ECCQ4.62, CCQ6, ECCQ6 — 7 gauge; all others — 3 gauge

Finish

  • Simpson Strong-Tie gray paint; available in HDG and stainless steel; CCOQ and ECCOQ — no coating

Installation

  • Install 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. (Lag screws will not achieve the same load.) Install stainless-steel Strong-Drive screws with stainless-steel connectors.
  • CCOQ and ECCOQ column caps only (no straps) may be ordered for field welding to pipe or other columns. Dimensions are same as CCQ and ECCQ. Weld by Designer.
  • For rough-cut lumber sizes, provide dimensions. An optional W2 dimension may be specified with any column size given. (Note that the W2 dimension on straps rotated 90° is limited by the W1 dimension.)

Options

  • For end conditions, specify ECCQ.
  • Straps may be rotated 90° where W1 ≥ W2 and for CCQ5-6.
  • Other custom column caps are available. Contact Simpson Strong-Tie.

CCQ/ECCQ Load Table
  1. Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
  2. Downloads shall be reduced where limited by capacity of the post.
  3. Uplift loads do not apply to spliced conditions. Spliced conditions must be detailed by the Designer to transfer tension loads between spliced members by means other than the post cap.
  4. Spliced conditions must be detailed by the Designer to transfer tension loads between spliced members by means other than the column cap.
  5. Column sides are assumed to be aligned in the same vertical plane as the beam sides. CCQ4.62 models assume a minimum 3 1/2"-wide post.
  6. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions resulting from narrow-face installations.
  7. Beam depth must be a minimum of 7".
  8. For 5 1/4" engineered lumber, use 5 1/2" models.
  9. CCOQ and ECCOQ welded to a steel column will achieve maximum load listed as CCQ and ECCQ. The steel column width shall match the beam width. Weld by Designer.
