/diy/ - Do It Yourself

two options:

A: hope bolt unscrews. Screw in rod in bolt and unscrew it.

B: Drill hole for new bolt

C: dunno lol :3

hahahahaha such a faggot rust

well now you have to drill new holes to bolt a new column down

I just realized that my old thread is still alive >>597325

But could someone help me out in this one?

>>598772
im more interested in how you removed the first column without everything come crushing down

>>598770
yes, rust is a huge faggot

>>598771
I just bought this house, so I have no idea how far down this goes. I don't think it will unscrew.


Could I jsut drill out the bolt and use the same hole with epoxy? Maybe with just a new smaller diameter bolt?

>>598772
I took some 2x6s and made a frame to take the weight in place of the beam I had to replace. Then I used a jack and another board to lift the awing up about a half inch. I removed the old beam and put the weight down on the frame I made.

>>598777
I should point out that I have this awning up on the temporary framing right now while I post this, so time is a factor. Though I wouldn't call this an emergency just yet.

>>598775
not recommanded... you dont know the condition of the broken end, you dont know whether it turns or when it will turn, so if you use it to secure things it will always be in queistionable sequrity, do u liek my spelimg

What if I just drill out the broken bolt as far down as I can go, and I put a new one in with epoxy?

>>598767
Dig out the anchor, pour new concrete, do it right?

>>598788
what do you mean as far down as you can go?

also... i dont know about using epoxy as a building material, it sounds like a stupid idea (that doesnt work kind of stupid)

>>598788
that will probably work, they also make nailguns for mounting things to concrete

Why not just offset the new post. A few inches to either side to allow for a new bolt shouldn't make a big deal

>>598813
When I say epoxy I mean proper sealant used in concrete/anchor applications

Update: What I have done so far is to drill out the bolt about 2.5 inches. I believe it goes all the way down to the bottom of the concrete pour. According to the instructions on this sealant stuff I have, 2.5 inches is enough for a half inch anchor bolt. After I used up all my darn drill bits I seated the new bolt with sealant, and it was "work ready" in 5 minutes. I didn't tighten down much on it, since I only need it for lateral stability.

I was giong to do this, but it is on the corner of the concrete so I don't want to move it

>>598767

Use a core drill to take out a slug around the broken bolt. Get new bracket and cement it in place as normal. Remember to use non-expanding cement.

Use a chisel and hammer to remove a 'small cone' of concrete from around the bolt.
Use Vice Grip® pliers to grip the exposed end to remove the bolt.
You may need to allow some version of rust breaker to penetrate around the bolt before it will turn.
Use enough epoxy to fill the cone void when you replace the bolt and bracket.
(this is why i suggested just raising the post, knocking out the rusted part and using treated material glued to the concrete instead of trying to replace the bracket in your first thread)

This will not work. If it could, the bolt would have turned out of the concrete before it snapped off. The fact that it broke at the surface proves the concrete holds with more force than can be applied as torque through the bolt.

>>598868
Drill two new smaller holes at diagonals to the one in the concrete.
Drill matching holes in the bracket.
Use two smaller bolts to replace the one larger that you're leaving in the concrete.

expensive

>>complicated
simple and cheap

OP here

I drilled out the bolt and put in a new one with sealant. The brackets replaced. The beams replaced. Done. Vertical stability is reduced, and lateral stability is as well but I have enough lateral stability to get by. I live in an area without any severe weather or wind.
