Capital Block for Post and Beam

Capital Block for Post and Beam - 12/13/17 04:13 PM

I've got an old post and beam that we're are installing a new post in. The two beams above lap over the main beam and it was suggested that we install a capital block under the lapped joints that will then be above the new post.
I've tried to research capital blocks for ideas, but only found one reference in an old timber frame article.
My questions: how thick should the capital be? And are there any images out there of examples?

Thanks in advance,
Chris

This is a Jim Rogers drawing and the term most used is bolster.

Hello Chris,

I believe that possibly your difficulty in getting good web research results is due to terminology usage???

I am providing a link to a new Pinterest Pages below that covers...Corbels. This is another proper and common term in English for these timber frame structural element.

I will add to this Pinterest page in due time to have other examples from other timber framing cultures. Corbels are part of the bracketing family of structural elements and distribute loads over a greater area while also bracing the frame to lesser or greater amounts depending on application...

In there "half version" they would be called a bracket, corbel bracket or half corbel, which is also a Corbelling element. However, they serve and function differently.

Full Corbels (what it seems you are looking for...not a Capital which is typically more decorative than structural) can serve many different functions. I will also attach a link to a project recently finished that uses many of the in stead of oblique bracing...

Let me know if I can be of further assistance...and good luck.

Regards,

j
