Strange construction sighting

[drsportster]

A building in my town had concrete walls with large steel braces on an angle like they were holding up the concrete wall . I have seen this before the next day they were gone and the holes where they were mounted were already patched up . A wall can't stand on its own gravity ?

Likely precast wall panels. The braces come off after the roof structure is installed.

Precast walls. Those braces are what holds the walls up until you put the roof on. Then the braces can come off.

It is the commercial construction method of choice in Australia. Called ' Tilt up slabs ' construction it has almost completely replaced concrete block masonry.
The walls are self supporting and bracing once at least two at right angles are erected. Unusual forged steel " hairpins ' are used to link the tops of the slabs erected inline , they resemble large hair pins with flat tops that are belted into inserts in precast slots .

Obviously it can, because as you said the braces were gone the next day.

Not sure why you think bracing wall panels is "strange." Have you ever seen a conventionally-framed wooden house being built? Braces are used to hold the walls plumb and straight until enough of the structure has been assembled for them to stand on their own. The forms of poured concrete walls are braced to hold the walls straight and plumb until the concrete hardens. Even block walls are braced temporarily.

Poured concrete or block? Could have been braced for wind until more of the structure was on.

Here in Texas the process is called “tilt wall construction”. Most all of warehouse or big box stores are built using this form of construction. Cheaper & faster than any other form of construction.

Lot of tilt up around here. I worked on a few before I retired. Walls are poured on site with a lifting system installed in the wall. Let cure for 5-7 days rig'em and stand'em up. Then bar joist ties the tops together and waula you got a building. Back a few years ago the Amazon tornado (10 miles from my house) took the roof off one and the walls came down. I can't remember now how many got killed. Google I-255 I-270 interchange and you'll see a bunch.

So the walls are poured on site laying down Then raised up

Not down here . They are made at a factory and transported vertically or close to it by truck .

There are a couple outfits in this region that make the wall panels at their facility, then truck them to the construction project. Notably a couple Amazon warehouses a few years ago, and a data center that is under construction. It's also worth noting that moving oversize loads is a non issue here.

Sometimes, yes. Never seen it done that way "here". Panels are all made at the precast plant and then trucked to the jobsite.

The large steel braces were holding the wall up. They are temporary until they tie the sections together and get the roof on.

When one of those tilt ups contents catches fire, you better be able to calculate the height of the wall, and stay farther away than that distance. When the steel connectors fail from heat impingement, they have a tnedency to fall outward, in a dramatic fashion. Safest place is at the corners.

Yup. They built a big plant by where i worked by pouring a very large floor then forming individual wall panels and pouring them. Then after curing standing them up.
