CCCQM Cross Column Cap for GFCMU and Concrete Piers
Product Details
The CCCQM embedded column cap is designed for use in raised pier foundations and applications where heavy beams rest on concrete or concrete block columns. The heavy-gauge beam seat and unique Simpson Strong-Tie® SSTB® anchor bolts provide the high uplift and lateral resistance needed to help resist high-wind events. The CCCQM is for use along a floor support beam with a stirrup on each side of the main channel to accommodate intermediate support beams at 90° angles.
Key Features
- Screws are configured to provide high uplift design values
- Certified welds for confidence in strength and loading
- SSTB offset allows flush installation to edge of pier
- SSTBs spaced to fit standard CMU cells
Material
- 7 gauge
Finish
- Hot-dip galvanized or Simpson Strong-Tie gray paint; see Corrosion Information
Installation
- Install 1/4" x 2 1/2" Strong-Drive® SDS Heavy-Duty Connector screws (provided) in all round holes. (Lag screws will not achieve the same load.)
- Min. (4) #7 vertical rebar (total for pier).
- No additional welding is allowed.
Options
- Available in widths up to nominal 7-1/8" width.
- For variable widths on side stirrups, specify W3 or W4 (3 1/4" to 7 1/8") and add an "X" to the end of the core model name. Example: CCCQM5.50X-SDS, W3 = 3 5/8", W4 = 3 5/8".
Ordering Information
- Configurations for many different beams or beam-to-beam combinations can be manufactured (refer to Post-to-Beam Selector).

- Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
- Total uplift load and lateral load is based on tested anchor failure in the pier.
- Allowable loads are based on either a 16" square grout-filled CMU pier with f'm of 1,500 psi or a 16" square CMU shell filled with 3,000 psi concrete. A minimum of (4) #7 vertical rebars are required. The designer shall design and detail the GFCMU/concrete pier to resist all forces including uplift, shear and moment.
- Pier height per designer.
- Side beam and main beam uplift loads assume DF/SP members and are not additive.
- The allowable loads listed for grout-filled CMU apply to solid concrete piers of 2,500 psi concrete a minimum of 16" square.
- The allowable loads listed for CMU shell-filled with 3,000 psi concrete apply to solid concrete piers of 3,000 psi concrete a minimum of 14" square.
- Any side stirrup not fully supported by grout- or concrete-filled CMU has an allowable download of 7,000 lb.
- Fasteners: SDS screws are Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
