The RPBZ retrofit post base is designed to reinforce existing posts and columns. The single, versatile model will fit on any size post consisting of a double 2x4 or larger. RPBZ can also be used to reinforce new post-base connections, such as braced carports, patio covers, decks and other structures. The RPBZ can be installed with the CPS composite plastic standoff to meet a 1 in. post standoff code requirement. A single RPBZ can be installed on a post that is flush to a corner, and two RPBZs can be installed at away-from-edge conditions to fortify the post-base connection to resist both wind and seismic forces.

Would these be good to put up 4x4 on existing wood deck?

• The RPBZ retrofit post base is designed to reinforce existing posts and columns. • The RPBZ can also be used to reinforce new post-base connections, such as braced: carports, patio covers, decks and other structures. (braced is the important word here). • The RPBZ post bases do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations (such as fences or unbraced carports). The top of the post must be restrained from moving horizontally by some other means, e.g., by tying the roof into a supporting structure or by adding knee bracing between the posts and beams. • Please see https://www.strongtie.com/products/connectors/wood-construction-connectors/technical-notes/bases-caps-general-notes Failure to follow all of the notes and instructions provided by Simpson Strong-Tie Company Inc. may result in improper installation of products. Improperly installed products may not perform to the specifications set forth in this catalog and may reduce a structure’s ability to resist the movement, stress and loading that occurs from gravity loads as well as impact events such as earthquakes and high-velocity winds.

can I use for existing concrete foundation to 6X6 post for screen in porch? for 6X6 post, i have ...

Asked by happyhome April 29, 2019

Answers

Hi. Couple of things. 1) these are designed for double 2x4s, which conjoined are slightly smaller than a 4x4 post, so it's too small to completely support the 6x6. 2) It's unattractive and difficult to trim around, if aesthetics are important to you with this project. There are much better options for attaching structural support posts to concrete, such as the Simpson CPT 66Z (6x6) & Simpson CPT 44Z (4x4) when aesthetics are of concern. Otherwise, try the ABA 6x6 or ABA 4x4. But will be to be secured in the concrete with concrete epoxy adhesive. I'm giving you the 4x4 codes because using 6x6 posts for a screened porch may be overkill. 6x6s are commonly used for decks exposed to the elements and that by code in most Maryland jurisdictions, must be built self-supporting. Screened porches see roofed and generally you'd want the roof support posts closer together so your screening fits nicer. Anyway, that's just a thought--definitely check with your architect, engineer, or the county engineers to ensure you're in compliance. Hope that helps.

will a post sleeve fit over this

Asked by will April 23, 2019

Answer

If you are using a 3-1/2 P T post the post sleeve will fit over the post base, it you have one that is tight take a pencil mark the outline of the post base, then take a chisel and a hammer and trim it until it fits, best to measure each post and measure the post sleeve before you buy them at the home depot store, we use the same post base a lot never had a problem with them fitting.

Can these be used to anchor 4x4 posts on a carport that has one side attached to a brick wall?

Asked by DYIGuy March 16, 2019
2
Answers

If I understand correctly, one side of your carport roof is attached to a brick wall, and the other will be supported by 4x4’s. I would say yes, these would work, I would probably use 2 on each post. Another consideration is that using these brackets will mean your posts will be sitting directly on the slab, which may ultimately lead to water degradation of the wood. I believe Simpson makes other brackets that create a separation between the two. Google may be your friend here.

Answer

We use these corner brackets a lot, the PVC sleeve will fit over the bracket if you counter sink, or tapper the holds slightly and use a flat head galv. screw, The best way is to trim the corners of the post and recess the bracket, you can modify the base a little if you have a grinder with a metal cutting disk to make the trim fit, beware you will lesson the structural integrates of the bracket when you modify it.
