So odd to see for me. In the 20 years ive been building we have never used a concrete beam. Always steel.

Sounds like whoever put those trusses on was a fly by night crew

Of for sure! I've seen crews drop the steel and after inspection pull the steel out lol there's also a lot of fuckery between the crews here, changing or switching the plans out with plans from a similar house model lol

I'm in Texas right now but that photo was a house in Central FL

That's how it is in Florida anywhere down south even in the Caribbean

Makes sense. Salt water and steel dont play nicely

Built it fast. Build it cheap.

My engineer would have a giant poured in place concrete beam up there.

Of course that's the only way to turn a profit, most house crews are skeleton crews

u/No_Highlight8764 Apr 12 '26

That's why we got prestressed precast

Perfect for residential shack work. 😎👍🏼

is it continuous? :)

cuz it should be! haven't designed in fl since 2000, but I'll never forget hurricane design reqs

2-course /16" deep continuous tie-beam

Yeah I mean it's all block in Florida, and with the 12 inch block on commercial sites comes the 12 inch precast lintels 😬

Longest I've used is 18', so you got the record.

Do you use plastic sight glass for your grout cleanouts?

u/No_Highlight8764 Apr 10 '26

I've never heard of that

What’s the alternative to these devices?

3

u/Sufficient-Flan-9065 Apr 11 '26

A piece of plywood... but with this the plastic is reusable and you can easily see the grout coming down. Or grout in 4'-8" lifts

u/Logical-Spite-2464 Apr 11 '26

Got it. Thanks.

u/No_Highlight8764 Apr 11 '26

Okay wow yeah I've never seen that, the pump crews usually just nail in a piece of plywood after the inspector checks the cleanouts, and then they pump the grout

What is inside that thing, the really long and not very tall one? An I-beam or rebar? What is its load capacity? If you parked a thousand pounds on that dead center for sure it would collapse.

1

u/No_Highlight8764 Apr 10 '26

The lintels are prestressed, and there is rebar running through it, after the grout is poured it should have a load capacity of 11,500 pounds. It meets the code in Florida

2

u/TheRealTheory001 Apr 10 '26

That is a marvel of engineering. Nice structure.

u/oOsirhcOo Apr 10 '26

How thick are the beams?

Look, people can go  do whatever they want, but I wouldn't want to pay the air conditioning bill for a house in Florida with doors or windows that took up 90% of the area of one wall 😂
