Why?

[bluedog225]

This is the door for the elevator control room in the garage of a houston hospital. I like it but can’t imagine why this door was needed.

It’s not waterproof. There’s a 1/2 gap around the edge.

It would look good on my cabin though.

Maybe if the elevator comes crashing down (wait- is this at the bottom or the top of the elevator shaft?) it will keep pieces of the elevator car from blowing a normal door off the hinges?

Strange that there's a gap. The manufacturer of that door "Presray" makes watertight flood containment doors. I'm thinking the edge seal is inflatable, hence the gauges on the door.

Maybe somebody FUBAR'd the door over the years? I can see them wanting a watertight room to prevent damage to the lift equipment.

Inmate/arrestee elevator? Probably a retrofit for a condition that wasn’t anticipated during design and construction.

 

[bluedog225]

The hospital was built after Harvey. I bet it’s just not finished out yet. Typical big organization nonsense.

Someone in procurement had a buddy working at presray?

 

[bluedog225]

There’sa pressure fitting in the door. And a compressor mounted on the wall.

It’s rehab hospital. “Finished” in 2019.

Good pics to clarify. It's a pressurized flood containment door.

 

[whitesco]

I was going to make a wild-**** guess and say a door to contain a sudden release of high-pressure hydrolics or something used by the elevator. But yeah, flood containment makes a lot more sense.

That is actually an airlock for a stargate that was hidden by building a hospital over it.

You go in there and you'll get sucked out into space.

will soon be a thread on GJ

"Show us your watertight/floodproof door"

Hopefully there is an interlock to keep the elevator from going down into a flooded space.

Why?

Seems to me that's in a basement, and for the control room. Sealed door keeps the control room dry and let's the elevator run.

built in LOTO on each of the latches?

 

[bluedog225]

A woman died in Andrew by taking an elevator down into the floodwaters. Rough way to go.

 

[bluedog225]

Loto?

Hey I forgot to order the machine room door, what do have in stock? Ah..well we've got a door off an old submarine, I'll make you a deal. Sure!

I like your positive attitude!

 

[Lassen Forge]

If you picture an elevator car in an elevator shaft, as it goes up and down, it (like a hydraulic cylinder and piston) displaces the volume above and below it. The door is designed like that to keep nosey people and ne'er do wells out of the access to the bottom of the elevator shaft but allow the air to vent out of the shaft at the bottom, so the walls don't blow out.

It is for the jerk that farts in the elevator.

 

[GreenIron]

The door is swung into place during a flood event. Slide locks are engaged. Are supply is connected to manifold to inflate the perimeter seals, preventing water entry.

Now that makes sense.

i like that, it be great for my concrete hurricane shelter

Fixed it for you.

Inflatable gasket? I think that's the reason you're seeing the gap. Nobody ever inflates it. In fact it looks like you have two inflatable gaskets.

Yes.

Yes.


Notice that one slide lock is slid in place and padlocked to keep the riff raff out in the OP's pictures.

When downtown flooded (not just downtown) few years ago it was a disaster. The city not wanting a repeat of that, supposedly installed doors to prevent it from happening again.
