…Don't just dismiss the hotmix. Concrete is a lot of money. 

The slab could cost as much as the rest of the hangar!

 

Regarding joint lines in concrete slabs: good idea to make sure they’re in the right place, because some pilots use them as aiming points when taxiing into the hangar.

 

After smashing a club-mate’s wingtip strobe, I painted white guidelines on the floor and extending outside onto the apron, to make it easy to line up wide aeroplanes.

 

Our neighbour has built a new hangar to accommodate three Air Tractors; it’s wide, but not deep, so no aircraft has to be moved to get another one out (which is the problem with our club’s building).

 

We added bi-fold doors. They might be cheaper, but are a menace in any sort of breeze.

A typical light industrial slab is 125-150mm thick and reinforced with a single layer of SL72, SL82 or perhaps SL92 mesh laid about 40mm down from the top surface. The edges should be thickened to abo

All concrete can bend and reinforced concrete is load carrying. It does not need to be pre stressed or post tensioned. those processes only increase the load carrying ability. As far as bending g

Question re: hangar doors.  Wouldn't it make sense to use a hell of a lot of hinges and build extremely big concertina doors?  Tall but narrow, running in tracks top and bottom.  Thinking maybe 1 - 1.5m wide, hinged to the next one.  Shouldn't be an issue with wind, pretty strong because of the track connections every panel, allows pretty much full width opening apart from the combined thickness of the panels, can be built from whatever you can get cheaply.

Downsides would be hard to seal especially top and bottom (maybe a rubber flap fixed to the frame), and the cost of the track hardware - although you could design/manufacture that yourself.

It is a good idea to limit door size. that is what decides if it is too windy to fly for me. If I cannot control the doors I can't fly, even though the plane would be able to handle the wind.

will probably be sliders now due to structural excesses for supporting a rather heavy tilt door.

Yes fabric on them is quite common.

The traditional set up is heavy overlapping sliders that leave the entire opening available and hang on wheels at the top in a "U" section with a slot guide at the bottom sitting in concrete.. The supports are adjustable to allow for wear and readjustment.  When closed up there's a pin to each overlap and a padlock for the last one. That gives you a bit of security.. Are you putting power to it?  Nev
