The truss comprises 2x4s

top and bottom chords are 2x4s

Although 2x4s are (technically) dimensional lumber, no one would ever confuse them for capital-D Dimensional capital-L Lumber, i.e. Anything you'd use for a floor joist

which means this floor is not framed from 2x4s "on flat" as Nola hastily assumed. Rather it is a floor with truss-joist framing. Which trusses just so happen to be made from 2x4s.  

Which is very different

you can't frame a floor of any significant span with 2x4 dimensional lumber

but you can sure as hell span a decent distance with a truss comprising 2x4s

(ex-architect with a concentration in structural engineering)

I'm thoroughly appreciative of trusses and how they work as a system to be greater than the sum of their parts (compared to being used as components alone, just as joists).

I'm just saying it's the first time I've seen that configuration in particular.  I've seen it with the 2x4s 90 degrees oriented from the picture.  I understand it's easier to nail the diagonals as shown in the picture, just not as strong as it's covered on both sides by flooring and ceiling.

Almost all of this type of truss as well as steel bar joists are made in this general pattern. There are some perpendicular members, but the triangular panel points are key to their design. I don't think it has anything at all to do with ease of assembly, rather it provides the highest strength in relation to the overall weight of the truss or joist. 
 We might be saying the same thing as I'm not 100% sure I understand what you wrote. Sorry if that is the case. Prolly is.

I think it is fairly common for floor trusses to be constructed "flat" - http://andersontrussnc.com/floor-trusses/

Always kind of puzzles me why roof trusses don't also have the top cord "flat" to provide more nailing surface. Far too many tract house builders don't get the nails into the "meat" of the truss when nailing down roof sheathing which can dramatically impact a roofs resistance to maintaining its integrity in a hurricane.

I trussed a chicken once. I'm no engineer but it probably wouldn't support a roof.

Just opened up the floor in our bedroom. Happens to be directly over where we want to install a light fixture in the LR below. Now I get to snake wires in the walls and in the crawl space. Fun times!

@NC_Egghead  Hey, that looks familiar...

I got my electric roughed in all the way to the switch in the LR. Had to change a single gang box to a double. Under the house in the crawl space was the worst part of the job. I've got 2 inspection holes to fix which isn't too bad.

Here's the room below where the fixture is hanging:


And the the opposite corner of the room where the junction box is:

Started working on patching the 2 inspection holes up...

St. Louis cut spare ribs, slice about 75℅ of the way between each rib. Rub all exposed surface. More bark and rub flavor is the idea.

Just finished lunch. Cooked fast, ran around 300* +/-, around 2.5hours. Not sure I'll do them like this again or not, they didn't texture wasn't consistent. The exposed area cooked faster than where they were still attached. Might need to work on how I cut them before cooking. Anyway, they tasted good.

See that rib 5 in from the right? Looks kind of funny, huh? Yeah, I pulled a piece off before the rack came off.


Here's the rest.

Well, that was quick.  Just shy of four hours, started at 230 and crept up to 290, never looked or flipped and they're bendy and soft.

Went healthy tonight since we are doing a cul de sac breakfast tomorrow on the blackstone. Costco stir fry veggies and squash and other stuff. Cooked them down then added quinoa and eggs like fried rice and some liquid amino. Can't believe I waited so long to get the blackstone.

I didn't think the Blackstone could cook anything but proteins??

It's actually stronger to have the 2x4s on flat in that truss than vertical

in a H profile (what a lot of people call an I-beam), the flat flange is what provides the (majority of the) moment of inertia. The thicker that flange (and of course the further from center), the stronger it is

if you had two trusses both twelve inches deep (total overall dimension) one with a flat top/bottom chord and one with vertical top/bottom chords, the 'on-flat' version wood be stronger

Big pizza and football night with a bunch of friends.  Someone brought a few cauliflower pizza doughs, so for the last we had to balance the healthy by making a triple pig.  Rib meat, bacon and prosciutto on a garlic sriracha sauce base with some candied jalapeños.  No other pics.
