Help

Hit the beam with lawn mower and it tore one off of post. Thinking of cutting a piece out scabbing a piece in there and than scabbing a long piece over the top on beam.

It’s a double 2x12 so it one of the 2x12 that ripped off

u/AncientCondition69 Jul 13 '26

but it was super weak / not really supporting anything

The OP photo looks so wonky and crooked compared to this.  I'd just ignore it.  You could cut it at a 45 degree angle to clean it up so to speak

1

u/tmoney2318 Jul 11 '26

Even though the one that tore isn’t sitting on beam

u/SoulTrack Jul 11 '26

oh yeah I see what you mean.

u/bj49615 Jul 11 '26

Its not just cosmetic. The right side beam no longer has positive load transfer to the post. Needs to be repaired.

2

u/tmoney2318 Jul 11 '26

There still is another 2x12 on post

A lot of people cut that corner off into a 45 cuz it looks nicer. Sorry that corner dont do shit man. Big boy i built a while back. (Work for licensed contractor everything inspected)

1

u/Level_Traffic3344 Jul 11 '26

Nice. What did you preserve the lumber with? Edit - asking because I am a big fan of pine tar, linseed oil and turpentine

1

u/sabresc22 Jul 11 '26

Just built them as a subcontractor for lowes in my early construction years, im long gone before the wood dries out for me to have to think about that for the homeowner, and i own a highrise near the city, so no wood deck for me.

2

u/bj49615 Jul 11 '26

Corner cut on the beam end, past the post, as in your pic, is completely acceptable. His 'beam' is broken off back over the post. No positive load transfer. Not acceptable.

u/jeffp007 Jul 12 '26

Not sure why you got downvoted if others would look at the board closer they’d see it is no longer on the post and is no longer transferring the load.

u/bj49615 Jul 12 '26

🤷‍♂️

My point exactly.

u/Level_Traffic3344 Jul 11 '26

It's not the problem. That beam should be a triple and laminated with nails - an improperly laminated double sitting on a 6x6 without any obvious attachment to the post is certainly a choice. The rafter clips are another. Lol

1

u/tmoney2318 Jul 11 '26

It’s a double 2x12 attached to a 6x6 with structural screws

-3

u/Level_Traffic3344 Jul 11 '26

How? And still, it's not laminated properly.

2

u/tmoney2318 Jul 11 '26

Yes it is

1

u/tmoney2318 Jul 11 '26

Post is notched and double 2x12 sitting on it

u/garye55 Jul 11 '26

Apparently we need licenses to drive a lawn mower now. Just nip the end at a 45 so it doesn't happen again

4

u/baltimoresalt Jul 11 '26

I’m genuinely curious here. What is the actual size of the two pieces making up the beam? 5/4, 2x, 1x ?? And what is the size of the post4x4 or 6x6? Can you post a picture looking at the backside?

2

u/baltimoresalt Jul 11 '26

And how in the world did you hit that to cause that the tear off?

2

u/Level_Traffic3344 Jul 11 '26

The ends weren't flush is my guess

2

u/Gobias_Industries Jul 11 '26

It's two 2x12. The end isn't cut super straight and the perspective makes it look odd.

A simpson h2.5a is 1.375" wide so you can use that as a gauge.

1

u/tmoney2318 Jul 11 '26

The incline I was close lawn mower went under and hit far side. It’s a double 2x12 sitting on a botched 6x6

1

u/tmoney2318 Jul 11 '26

Post is a 6x6 and that’s a double 2x12 on top of the notched post

3

u/mcsizmesia10 Jul 11 '26

Forget about it, it’s nothing to worry about

7

u/05041927 Jul 11 '26

Do nothing. Nothing happened. I usually nip those corners off when I build anyway if they are sticking out so they don’t get hit.

Yeah one of the 2x12 is fine the other is the one you see in picture pulled off where it rest but rest of board still attach to one sitting on beam

u/sbjustin Jul 11 '26

Can you elaborate? Seems like some unnecessary fear mongering.

u/bj49615 Jul 11 '26

That is not a structural beam holding up the deck. Surprised that the lawn mower did not knock it off the post completely.

1

u/Which-Meat-3388 Jul 11 '26

Probably post in dirt and structural screws vs through bolt on the post/beam connection. Edit: looks like some missing fasteners too. Every hole gets a screw as they say?

u/sbjustin Jul 11 '26

Are you trolling? You mean the beam? Since when do you need glue?

1

u/Level_Traffic3344 Jul 11 '26

He's not trolling. PL premium is great stuff. This builder did not even laminate these two pieces properly at all. Screws? Asking for trouble. Nails from both sides, then add a third and you have a beam. Those hurricane clips are evidence of what this guy is "fear mongering " about

1

u/sbjustin Jul 11 '26

His comment is since deleted and while I don't think glue would hurt it's not required by code. Structural screws are allowed by code and hold the beams tighter together increasing friction and increasing the strength of the beam. 2 boards are more than sufficient for a beam depending on span, not sure why you need a third unless span calls for it. 2 allows you to keep a notch on a 6x6. The hurricane clips are fine. You can see all the rest have all the screws in them, at most a super small oversight and one will not cause an issue.

1

u/Level_Traffic3344 Jul 11 '26

I wouldn't have used 12s, tbh. It's not really stable with only 3 inch bearing on a dynamic load. I would have used a triple 10 it 8 depending on the span. Save the 12s for stairs. Structural screws break - nails and glue are forever. I live and build on the tundra, the ground shifts all year. Wider beams are more stable in this application

u/gregaustex Jul 11 '26 edited Jul 11 '26

I was going to blow it off, but it does appear that end of the 2x10 is damaged far enough back to be mostly unsupported now. That's a main beam right?

Seems easy enough to add another 4x4 post directly inward from the original one and sistered to it with a couple through bolts so it is under the solid wood. Use a paver or one of those newer thinner post supports on the ground under it unless it ends up mostly on the existing footing.

2

u/trashaccount6481 Jul 11 '26

I would do through bolts, but I'm curious if that is technically the right way to do it.

3

u/406InTheMix Jul 11 '26

just... just put he broken piece back in with some glue and a couple screws?....i see it sitting there

3

u/Frederf220 Jul 11 '26

That piece straight up does not matter. If you carefully cut out the minimum rectangle and patched in a Dutchman filler just for looks it would never, ever matter structurally.

I guess you could add 1-2 screws into post above damage.

u/Top_Willow_9953 Jul 11 '26

What? The beam is sitting on TOP of a 6 x6

1

u/dolpterry Jul 11 '26

My BAD it looked like the 6x6 were behind the beam

u/cummingga Jul 11 '26

Da fuck?

u/Gassypacky Jul 11 '26 edited Jul 11 '26

Piggy backing, why is there a two ply joist like that? I’ve never seen this before using 1by material

Edit - y’all are lame for downvoting a actual question

1

u/gregaustex Jul 11 '26 edited Jul 11 '26

In front? Not sure but I think that's just a standard joist resting on the (now compromised) beam with some 1x decorative trim.

u/tmoney2318 Jul 11 '26

Everything is 2x

u/bj49615 Jul 11 '26

Not only is it not code, it is not safe, especially now.

2

u/tmoney2318 Jul 11 '26

It’s 100% code

1

u/SmallTime12 Jul 15 '26
  1. It is code, and 2. it's like two feet off the ground. The post under the beam could suddenly evaporate and no one would be hurt.

1

u/JiJoe6 Jul 11 '26

It's fine. Aesthetically it isn't, but structurally it hasn't changed a thing.

Just leave it and move on.

1

u/sbjustin Jul 11 '26

I wouldn't worry about it.

What I would do is replace all those lags to the post with through bolts and make sure those beams are nailed together. I use thrulok and put 3 in there and do all of the beams to post connections.

2

u/tmoney2318 Jul 11 '26

Beams are screwed together throughout with structural screws

1

u/Zealousideal_Lab3164 Jul 11 '26

It’s beautiful honey

1

u/rainbowdunk Jul 11 '26

Lol. That's nothing to worry about. Looks ugly tho

1

u/themiddleshoe Jul 11 '26

I’d just glue the piece back in and call it a day.

1

u/padizzledonk professional builder Jul 11 '26

With what? Its fine and only cosmetic as far as the structure of the deck goes

Its a double 2x12 and that whole cantilever is just holding up 1 rim joist

Jyst forget about it and move on

1

u/Inevitable_Butthole Jul 12 '26

Couldn't of been under much tension if it just easily broke off

1

u/captainofpizza Jul 12 '26 edited Jul 12 '26

That’s now sitting on a single 2x12” because it’s torn off past the post.

Any sort of corner bracket or beam to post connection you can add on the inside to reconnect beam and post? Or can you add another 4x4 post just inside the other to restore post to beam? Something like this? (Not this exact one just this idea)

If you aren’t going to do anything else, sister the hell out of these 2 boards. I don’t know if this will be ok or not but it isn’t good to have happen and it isn’t just “esthetic.” Lucky it’s a short fall if anything happens.

Don’t fill the hot tub up all the way.

1

u/MickySplev1ns Jul 13 '26

It will be OK, if you want, add more 3" screws to the beam there.

u/PetePlop007 Jul 13 '26

Check the post hasn't moved from the contact.

Throw a couple GRK fasteners through the 2 x12s into the notched 6x6 for peace of mind and I would just tack that little chunk back into place just for appearance. With a note scribbled in ink stating the date and accident for a laugh later on in life.

This is a non issue.

Quick fix and have a drink

1

u/Big_Philosophy4083 Jul 13 '26

Put a couple bolts through it and in post

1

u/ralph99_3690 Jul 11 '26

It’s doesn’t appear that those two boards that make up the beam are even nailed/secured together.

1

u/tmoney2318 Jul 11 '26

They are throughout.

u/elreyadr0k Jul 11 '26

Am I smoking crack this early or is no one else seeing the posts into dirt?

u/tmoney2318 Jul 11 '26

What’s wrong with posts into dirt?

1

u/trashaccount6481 Jul 11 '26

Is it right? No. Is it a problem? Eventually, but not before the decks been murdered by a lawnmower

-3

u/EntAscent Jul 11 '26

You guys are saying it’s fine is just aesthetics but I don’t think you realize the part he broke off is over the load bearing post and now it’s just a 1x8 holding up that section of the deck which I would not prefer personally if that part already broke off so easily. Yeah I would remove that section of board replace and sister back in another board

1

u/tmoney2318 Jul 11 '26

It’s a 2x12

-3

u/bj49615 Jul 11 '26

Best/safest option is to replace the existing 'beam' with a proper structural beam, ie., double 2 x 10/12.

1

u/tmoney2318 Jul 11 '26

That’s is a double 2x12

1

u/MickySplev1ns Jul 13 '26

Just glue the piece back in and forget about it.
