Wait a minutes, the rivets had to be hot? Of course, to make them smaller so that they'd lock in and never budge, but... why not lift them up and then heat them?

Heat them... in what? The furnaces used to heat rivets to a cherry red glow were heavy, cumbersome things. You'd have a single furnace that would supply all the riveters on the construction site. That's not something you can just lug around to within reach of each individual worker, especially if they're working on a level that doesn't even have a floor.

Maybe they had to re-heat them using butane torches as they passed them along or something?

Do they have to be THAT hot that they need to be heated in a furnace? That sounds so bloody dangerous that just the idea gives me shivers.

Steel is a lot harder to deform when it isn't red-hot. Cold riveting is fine in a factory setting, but for the large rivets historically used in construction, it would require impractically heavy tools.
Hot rivets have the desirable property of contracting as they cool, clamping the joint together. At lower starting temperatures, this effect becomes less pronounced, resulting in a looser joint.
I'm out of rivets~ (a tool)
Unless I'm missing the nuance of the word 工具, the artist might be mistaken here —rivets are a building material, not a tool
The 23rd of December is
The Day of the Completion of the Tokyo Tower!
Japan's largest radio tower, built back in 1958 in just a year and a half by a group of elite workers with basically no safety equipment at the time!
There goes—hoopDamn, if I fail to catch this I'll just die, right?!(Due to delays in construction work) The workers played a game of "death catch ball" by throwing tools as hot as 800ºC, at a height of 300m with no lifeline, to workers that were 20m above.
Same as above, what they threw was the rivets, that needed to be hot to be fastened to the tower. Apparently, they would catch them with a bucket before putting them.
