A few days ago I had a doctor’s appointment at a local hospital. We parked in the garage and walked over an enclosed pedestrian bridge to the office building.
Though I’d made a couple of other trips to this site, this time I saw something I hadn’t noticed before:
Yes, it’s this assemblage of oversized bolts, screws, and rods that caught my eye. I immediately saw the structure of this bridge very differently – as from the standpoint of – how is this thing actually put together and holding itself up so that I can travel across it without a thought?
Well, it’s simple. As you can see, there is a series of diagonal supports from ceiling to floor.
Halfway over the bridge they switch direction.
You saw the giant screw threads:
and how about these cotter pins?
I would have loved to see them putting this structure together. Below is the original view of the bridge I showed. Now, if you were to take a seat and relax here for a while, you’d feel pretty good about the glass tube this bridge pretends to be, right? Because it’s really a pretty brawny entity.
Keep your eyes open next time you’re in an office building or other such structure. Even if they put in ceiling tiles and so on…there are clues as to how the building works. It’s interesting to follow the clues.
By the way, above these ceiling tiles, which don’t cover the whole surface, it’s possible to see utility pipes carrying the building services over the bridge. Painted a slimming and hiding black, but they are up there…
