I am building two support collumns for a porch out of brick-----what is the pattern to get the smallest size?

Question

I would like to not go 12"x12"----I would like to go 7x7 0r 8x8
two brick ns two brick ew is the only way I can see it

Answer 1

It would depend if you want it perfect square, or have an unusual yet strong design in mind. Two on two, three on three,
three on three in reversed triangles, four on four, and four on four staggered . all have strength for support, but if you are limited to the number of brick,Two on two is the cheapest.

Answer 2

i would wind 4 brick around each course and add rebar in the center, each course would have one whole face and an end. the next course would wind the other direction.

never skimp on a foundation. if you make it too slender it won't be able to resist the lateral forces it'll see. and a slender column could only safely rise a few courses.

you really should have one or two rebar in the center with the void filled with grout.

i agree that you should have someone qualified review your plans. your local building dept should have an engineer you can talk to.

good luck

Answer 3

I would advise you to go with at least the 12 x 12 option. At that size, brick wouldn't have very much resistance to lateral forces and could be dangerous if it was the only means of supporting your deck. You should think about supporting your deck with 4 x 4 wood posts or 4" dia. pipe columns setting on appropriate foundations and then enclose them with a brick veneer. You should probably consult with a qualified contractor.

Answer 4

i agree with michael above. 12x12 is best. you might go 8x12 , but dont go 8x8. even with weight on an 8x8 pier, you can still knock it over with relative ease.
