Description
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.
Load Tables
These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.
For stainless-steel fasteners, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
- Uplift loads have been increased for earthquake or wind loading with no further increase allowed. Reduce where other loads govern.
- Downloads shall be reduced where limited by capacity of the post.
- 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.
- Spliced conditions must be detailed by the Designer to transfer tension loads between spliced members by means other than the column cap.
- 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.
- 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.
- Beam depth must be a minimum of 7".
- For 5 1/4" engineered lumber, use 5 1/2" models.
- 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.
