PBV Post Base (for Viga Post)

PBV

On This Page

The PBV is designed to make a hidden connection between viga posts and concrete. This circular, hidden standoff post base attaches to concrete with threaded rod and epoxy to the bottom of the viga post with Strong-Drive® SDS Heavy-Duty Connector screws for a secure connection. The PBV comes in two different sizes to support a variety of projects.

Key Features

  • Round shape to match viga-style posts
  • Black powder-coated finish
  • 1" standoff to help prevent rot at the end of the post

Material

  • 14 gauge

Finish

  • Black powder coat or galvanized

Installation

Post:

  • Drill a 3/4"-diameter hole, 10" into the center of the post.
  • Clean out sawdust. Fill hole halfway with Simpson Strong-Tie® SET-3G™ epoxy anchoring adhesive.
  • Insert all-thread rod while twisting the rod, and allow the epoxy to set and cure.
  • Secure standoff to post using four Strong-Drive SDS Heavy-Duty Connector screws (sold separately).

Concrete:

  • Drill a 3/4"-diameter hole per anchor design a min. 4 3/4" from the edge.
  • Clean out dust. Fill hole halfway with Simpson Strong-Tie SET-3G epoxy anchoring adhesive. Insert post subassembly into hole, and allow the epoxy to set and cure.
  • 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).

Ordering Information

  • For black powder coat, order PBV6PC or PBV10PC. For galvanized coating, order PBV6 or PBV10.

Load Tables

CPS/PBV Standoff Bases Load Table
  1. Allowable uplift load capacities are based on round “Viga” (ponderosa pine) wood posts.
  2. All allowable uplift loads are based on a lowest ultimate load from testing divided by a safety factor of 4. Concrete anchorage to be designed by others; refer to the Simpson Strong-Tie® Anchoring, Fastening and Restoration Systems for Concrete and Masonry catalog. Uplift loads shall not exceed those shown in the table.
  3. Downloads are calculated based on the standoff bearing area and a concrete strength of 2,500 psi — except the PBV, which is based on the wood’s bearing strength (700 psi for ponderosa pine).
  4. Allowable loads may not be increased for the duration of the load.
  5. 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.
